Description

Umbrella with anti-reverse mechanism

The invention relates to umbrellas, and more particularly to umbrellas designed to resist reversal in adverse conditions including strong winds and the like.

It is well known that an umbrella is a device that protects the user from the effects of the natural environment and particularly from the effects of liquid and ice precipitation or even sunlight. A traditional umbrella has the following parts: a pole, a canopy, a rib, a slider, a spring, and an umbrella hoop. The umbrella pole is a metal or wooden shaft that extends between the handle at the bottom of the umbrella (or abutment in the case of an outdoor model) and the umbrella cover at the top of the umbrella. The umbrella cover is the woven part of the umbrella that captures rain, wind and sunlight. The ribs are things that give the structure and shape of the umbrella. The outer ribs hold the umbrella cover upwards, and the inner ribs (sometimes called extensions) serve as supports and connect the outer ribs to the umbrella rod. The slider slides up and down along the rod, is connected to the ribs / extensions, and is responsible for opening and closing the canopy. Many umbrella designs include: a top spring to hold the slider up when the canopy is open, a bottom spring to hold the slider down when the canopy is closed, and sometimes a center ball spring to extend the umbrella rod in the telescoping model length. For decorative purposes only, a finial (also known as an umbrella hoop) is provided on the top of the umbrella, above the umbrella cover.

The umbrella ribs play a role in supporting the folded structure of the umbrella cover fabric. Under normal operating conditions, the force acting on the canopy fabric increases towards the peak when the canopy becomes fully deployed and when gusts tend to flip the canopy. These forces are transmitted from the canopy to the ribs of the canopy and can act on the ribs in opposite directions depending on the wind direction. Therefore, the ribs have to be strong enough to withstand the forces acting on the ribs from either of the two main opposing directions.

The above configuration is the most common configuration for umbrellas, and the umbrella cover assumes a downward convex shape. A major problem with this design occurs when there is a strong wind or sudden gust, which exerts a force against the inner surface of the umbrella cover, causing the umbrella cover to protrude from its normal position to the upward position. Position reversed.

Umbrellas have been proposed to address the problem of gusts, one of which is an arrangement of holes in the canopy that allows air to flow through the canopy, thereby reducing the total force experienced by the canopy. However, the pores are not large enough to provide sufficient airflow to greatly reduce the force, and in most cases the canopy is still inverted. Another solution to this has been to add a string from the umbrella pillar to the tip area. However, this solution suffers from drawbacks because these strings can become loose or cut or tangled over time during use.

It is therefore an object of the present invention to provide a windshield that functions to prevent the umbrella from reversing in strong winds.

According to an exemplary embodiment of the present invention, the umbrella includes an elongated shaft having a first end portion and an opposite second end portion, and a slider, the slider is slidably disposed around the elongated shaft and is movable along the length of the shaft . The umbrella has a plurality of ribs attached to the slider by a plurality of main struts moving between an open position and a closed position, wherein in the open position the ribs are in the open extended position, And in the closed position, the ribs are in the closed folded position.

According to the present invention, the umbrella has an anti-reverse mechanism formed by a plurality of anti-reverse pillars. Each anti-reverse post is pivotably coupled to a corresponding main post and is pivotally connected to a floating joint member that is freely movable along the length of the rib. The anti-reverse mechanism also includes a stopper that is fixedly attached to the rib and restricts the extent to which the floating joint member can travel along the rib, and is positioned to prevent the corresponding rib from reversing in response to the applied force.

As discussed herein, the present invention is an improvement over several components of the umbrella, including, but not limited to, shaft construction and its rib assemblies. As discussed herein, the features of the present invention may be implemented by a manual type umbrella and an automatic type umbrella. In addition, other features can be implemented by other types of umbrellas. Accordingly, the following discussion and drawings describe exemplary embodiments implementing the teachings of the present invention.

FIG. 1 shows a side view of an umbrella 100 according to an exemplary embodiment of the present invention, where only one assembly is shown for clarity and to simplify the discussion of the present invention. The umbrella 100 has a type commonly referred to as a golf umbrella, which is known as an oversized umbrella, which is used to protect golfers and their carts from rain. The long axis of a golf umbrella is usually not foldable. It will be appreciated and understood that the various features of the invention described herein may be implemented in other types of umbrellas than golf umbrellas.

As shown in FIGS. 1 and 14, the umbrella 100 includes a shaft 110 having a first (top) end portion 112 and an opposite second (bottom) end portion 114. The shaft 110 itself may be formed from any number of different components to cooperate to provide the shaft 110, and the shaft 110 illustrated in FIG. 1 is where a user manually opens And part of the manual umbrella assembly of the closed umbrella, as described herein. At the first end 112, a cover or decorative umbrella hoop (not shown) is typically provided to close the shaft 110, and at the second end 114, a handle 130 is provided for grasping by a user.

14-16, the illustrated shaft 110 is formed from a plurality of different shaft sections that fit together to form an assembled shaft. More specifically, the shaft 110 may be formed of three disparate shaft sections, that is, a first shaft section 111, a second shaft section 113, and a third shaft section 115. The first shaft section 111 is attached to the cover / umbrella hoop at one end and to one end of the second shaft section 113 at the other end thereof. The second shaft section 113 is attached to one end of the third shaft section 115 at the other end thereof. The third shaft section 115 is attached to the handle 130 at the other end thereof. Therefore, the first shaft section 111 represents a top shaft section; the second shaft section 113 represents a middle shaft section; and the third shaft section 115 represents a bottom shaft section. The dimensions of the individual shaft sections 111, 113, 115 may be different, and in detail, at least one of the length and / or width (e.g., diameter) may be different. In the illustrated embodiment, the sections 111, 113, 115 have the same width, but the middle section 113 has a greater length than the sections 111, 115, and the sections 111, 115 are shown to have the same length. For example, the three shaft sections 111, 113, 115 may be 14mm shaft sections made of carbon.

The shaft sections 111, 113, 115 are connected to each other by a coupling member 105. One coupling member 105 is attached between two adjacent shaft sections 111, 113, 115. The coupling member 105 may be considered as a shaft locking member (locking insert) and may be formed of a metal material such as aluminum. The locking member 105 may be a hollow member (tube) having a first annular ridge (lip) 107 formed along an outer surface thereof and a second annular ridge (lip) 107 formed along an outer surface thereof and spaced from the first annular ridge 107 Ring ridge (lip) 109. The space 108 is formed between the ridges 107 and 109. The annular ridges 107, 109 define stops for the respective shaft section. More precisely, the outer diameter of the locking member 105 outside the annular ridges 107, 109 is selected so that the locking member 105 can be inserted into the hollow interior of the respective shaft section 111, 113, 115 so as to form friction therebetween Fit (mechanical fit). Since the annular ridges 107, 109 have a larger diameter than the inner diameter of the shaft sections 111, 113, 115, the locking member 105 cannot be inserted into the corresponding shaft section. Alternatively, these annular ridges 107, 109 serve as stoppers and prevent the locking member 105 from being further inserted into the corresponding shaft section. When assembled, the surface of the locking member 105 between the two ridges 107, 109 is visible.

Therefore, the locking member 105 provides a rigid coupling member, which rigid coupling members The shaft sections 111, 113, 115 are firmly attached to form a fully assembled shaft.

As described above, one of the main components of the umbrella is the slider 150. The slider 150 is a part of the umbrella that opens and closes the umbrella 100, wherein the slider 150 moves along the shaft 110. Therefore, the slider 150 is a hollow member that surrounds the shaft 110 and can move along the shaft 110 and can be locked into one or more different positions. 17A, 17B, 18A, and 18B show the slider 150 in more detail. The slider 150 is formed from several components or portions including a generally cylindrical base portion 152 and a shaft slider lock 154. The top portion 153 of the slider 150 is configured to receive and securely attach to a plurality of struts, as discussed below, in order to effectuate the movement of the rib 200. Accordingly, the top portion 153 includes a plurality of slots 155 formed circumferentially therearound for receiving a pillar. The shaft slider lock 154 is located between the top portion 153 and the base portion 152.

The shaft slider lock 154 is designed to selectively lock the slider 150 into one of a plurality of locked positions along the shaft 110. 18A and B are cross-sectional views of the sliding member 150. 17A and 17B show the slider 150 in an unlocked (open) position relative to the locking member 105, and FIGS. 18A and 18B show the slider 150 in a locked position in which the slider 150 is locked with respect to the shaft (Ie, locked with respect to the locking member 105) in place.

Thus, the locking member 105 may be in the form of a machined part of aluminum (or other material) that provides a recess (space 108) for the slider 150 to connect to lock in place.

The shaft slider lock 154 is designed to lock and engage the shaft locking member 105. The shaft slider lock 154 is a push / pull slider that moves along the shaft. More specifically, the shaft slider lock 154 has an elastic locking member (slider detent) 157 which is engaged and disposed in a space 108 formed between the annular ridges 107, 109. The elastic locking member 157 may include a ring-shaped locking member 157 having an inwardly directed lip that is disposed within the space 108 when it is aligned with the space 108. The elasticity (deflection) of the locking member 157 allows the locking member 157 to flex outward, thereby allowing disengagement from the space 108. When the locking member 157 (and, more specifically, its lip 159) is disengaged from the shaft locking member 105, the slider 150 can move freely along the shaft 110.

In use, when the slider 150 reaches a point where it can no longer be moved vertically upwards, and then the pressure is directed to the slider detent 157, which locks itself to the locking insert 105. One advantage of this design is that usually one needs to swage or reduce the diameter of the shaft in some way in order to allow the slider to engage the locking mechanism, otherwise one would have to Add material to the outside of the shaft itself to make a locked position. However, adding material to the shaft is unsightly and also makes the folded diameter of the umbrella larger.

17A and 17B show the slider 150 in an unlocked position, in which the slider 150 is free to move along the axis. In this unlocked position, the slider detent 157 is not actively engaged with the space (recess / channel) 108, and in FIGS. 18A and 18B, the slider detent 157 is actively engaged with the space (recess) 108, and the slider 150 is then engaged. Lock to shaft. As mentioned herein, when the slider 150 is pushed, it reaches a point where it can no longer move in the vertical direction (such as the points shown in FIGS. 17A and 17B). The continuous application of the force against the slider in the vertical direction causes a force to be applied to the slider detent 157, and this causes the slider detent 157 to deform in a radially inward direction toward the locking insert 105.

The slider pawl 157 can be disengaged from the locking recess 108 by overcoming the holding force, which means that when a user applies sufficient force to the slider 150, the slider pawl 157 is disengaged from the locking recess 108, and the slider 150 Move freely.

As described herein, the locking member 105 is thus positioned along the shaft 110 to lock the slider 150 into desired positions, such as the fully open position and the fully closed position illustrated herein.

It will be appreciated that the slider 150 is merely exemplary and is not a limitation of the scope of the present invention, as other slider configurations may be used with the umbrella of the present invention.

In order to move the slider 150 along the shaft 110 in either direction (up and down), the user applies only sufficient force to cause the locking member 157 to disengage from the locking slot (space 108).

The umbrella 100 also includes a top notch 119, which is a ring-shaped member that is attached to and surrounds the shaft 110. The top notch 119 is configured to receive the ribs 200 and thus serves as an attachment point for such ribs. The ribs are attached to the shaft 110 by fitting into the top notch 119 and can then be held by wire or other means. The top notch 119 may be a thin circular nylon or plastic part with teeth around the edge.

As will be understood from the following description, each rib 200 is coupled to both the top notch 119 and the slider 150, and this results in the rib 200 and the attached umbrella cover (not shown) based on the movement direction of the slider 150. Show) opening and closing. The connection between the rib 200 and the slider 150 is facilitated by a pillar 300 (main pillar). The pillar 300 is an elongated structure having a first end portion 302 and a relatively first Two end portions 304, wherein the first end portion 302 is pivotably attached to the slider 150, and the second end portion 304 is pivotally attached to the rib 200. The pivotal connection between the pillar 300 and the sliding member 150 and between the pillar 300 and the rib 200 can be achieved by fasteners such as rivets or pins. More specifically, the first pillar joint 310 is formed between the pillar 300 and the slider 150 at the first end portion 302, and the second pillar joint 320 is formed between the pillar 300 and the rib 200 at the second end portion 304. between.

As shown in FIG. 6, the first pillar joint 310 may be in the form of a convex end joint configured to be pivotably attached to the slider 150 to allow the pillar 300 to pivot between an open position and a closed position.

The second strut joint 320 is in the form of a double joint, and is best shown in FIGS. 6 and 7A-D. The second post joint 320 can also be considered to be a post-to-rib joint and includes: a first end 321 attached to the distal end of the post 300; and a second end 322 including a pair of spaced fingers An object 323 parallel to each other and defining an open space 324 therebetween and forming an alignment opening therein to allow the passage of a fastener or the like to couple the head to another structure (rib ), As discussed below. As shown in FIGS. 7A-D, the second pillar joint 320 also includes a joint connector 315, which may be in the form of a fin, which protrudes outward from the main body of the joint 310 (that is, the connector 315 is perpendicular to the connection Body of the device 315). The joint connector 315 has an opening formed therein to allow a fastener to pass therethrough to allow another structure to be pivotally attached to the joint connector 315.

The pillar 300 may be formed from any number of different materials, including metals (eg, zinc alloys).

As shown in the figure, the rib 200 is an elongated structure that is coupled to other parts of the umbrella to provide a rib assembly defined by a plurality of ribs 200 that are opened and closed.

Each rib 200 is an elongate flexible structure having a first end portion (proximal end) 210 and an opposite second end portion (distal end) 212. The first end 210 may be pivotally attached to the top notch 119, and more specifically, the first rib joint 220 may be provided at the first end 210 and designed to allow the rib 200 to be relative to the top notch 119 pivoted. In the illustrated embodiment, the first rib joint 220 may be in the form of a convex end joint, which may have a structure similar to or the same as the first rib joint 310 as a part of the pillar assembly.

As best shown in FIG. 6, the rib 200 also includes Placing the second rib joint 230. The second rib joint 230 may be fixedly attached to the rib 200 at a specific position of the rib 200. The second rib joint 230 may thus be in the form of a hollow structure that receives the rib 200 and is fixedly attached to the rib 200 so that during use, the second rib joint 230 does not move but stays at a fixed position. The second rib joint 230 has a connector portion 232 in the form of a fin (projection) extending radially outward therefrom. The connector portion 232 may thus be formed perpendicular to the main body of the second rib joint 230. The connector portion 232 includes an opening formed therethrough.

6 and 7A-D, the connector portion 232 is sized and configured to be placed in an open space 234, where the open space 234 is defined between the pair of spaced apart fingers 323 of the second post joint 320. When inserted into the open space 234, the opening formed in the connector portion 232 is axially aligned with the opening in the finger 323 so as to allow the passage of a fastener such as a pin or a rivet or a wire, etc. The two-pillar joint 320 can be pivotally attached to the rib 200 (and therefore, the pillar 300 can be pivotally attached to the rib 200).

According to one aspect of the invention, the anti-reverse mechanism (feature) 400 is provided and configured to counter the reversing force applied to the umbrella during the selection of operating conditions and, more specifically, during windy conditions or other adverse conditions. As is well known to users of umbrellas, if a sudden gust of wind is directed upwards toward the inside of the umbrella, the pressure exerted by the wind will reverse the umbrella cover, causing the ribs to act in the opposite direction, forcing it outward. When the reversal occurs, the canopy usually assumes a concave shape, and similarly, the ribs are forced to pivot in unexpected directions, which can cause one or more ribs to break. This makes the umbrella unusable. The umbrella of the present invention has an anti-reverse mechanism 400, which is composed of several parts individually discussed below.

As shown in FIGS. 6 and 8A-C, the anti-reverse mechanism 400 includes an anti-reverse post 410. The anti-reverse post 410 has a first end portion 412 coupled to the pillar 300 and a relatively Two ends 414. More precisely, the first end portion 412 is coupled to the second post joint 320 and the second end portion 414 is coupled to the rib 200. The anti-reverse post 410 has a first end joint 411 at a first end 412 and a second end joint 413 at a second end 414. The illustrated first end joint 411 and second end joint 413 are in the form of a concave end joint, and in detail, the first end joint 411 is defined by a pair of spaced-apart fingers 415, the pair The spaced-apart fingers 415 have an open space formed therebetween, and the second end joint 413 is also defined by a pair of spaced-apart fingers 417 having an open space formed therebetween. space. Connector The connector 315 (male connector) is received into the open space between the fingers 415 (female connector) of the first end connector 411, and in such a manner that the anti-reverse post 410 can pivot relative to the post 300 The anti-reverse pillar 410 is coupled to the pillar 300.

The first end joint 411 and the second end joint 413 may be mechanically fixed to the elongated pillar body, or the end joints 411, 413 may be molded over existing pillar materials.

The anti-reversion post 410 may be formed from any number of different materials, including metals and synthetic materials. In one exemplary embodiment, the anti-reverse post 410 includes a 6 mm carbon fiber rod.

The anti-reverse mechanism 400 also includes a floating joint 500 which is slidably coupled to the rib 200 and is configured to cooperate with the second end joint 413. 8A-D illustrate a floating joint 500. The floating joint 500 has a main body 510 including a bore 512 formed in the main body 510 and representing a through hole passing from one end of the main body 510 to the other end thereof. The floating joint 500 also includes a joint connector 520 in the form of a fin extending radially outward from the main body 510. The connector 520 may be formed perpendicular to the main body 510. The connector 520 has an opening formed therein. Therefore, the connector 520 represents a male connector.

The anti-reverse post 410 is coupled to the rib 200 by inserting the connector 510 between the spaced fingers 417 of the second end joint 413. As in another joint, a fastener or the like may be used to couple the connector 510 to the finger 417.

The rib 200 is received in the bore 512 and passes through the bore 512, and the size (diameter) of the bore 512 and the size (diameter) of the rib 200 are selected so that the floating joint 500 can be longitudinally along the length of the rib 200 Free movement in the direction. This allows the floating joint 500 to travel freely up (toward the top notch 119) and down (toward the tip of the rib) along the rib 200 when the umbrella is opened and closed.

It will be appreciated that in another embodiment, the floating joint may be a convex portion including a male connector 520; however, it is positioned inside the rib 200 such that the floating joint is within the rib 200 (e.g., an aluminum extrusion rib) Or shaped steel ribs) move freely inside the hollow inside. The rib 200 may thus have a linear slot formed therein, with the connector 520 passing through the linear slot. The operation of the floating joint is otherwise the same. Therefore, in this alternative embodiment, the "floating action" of the floating joint occurs internally in the rib 200, rather than on the outside of the rib 200 in the illustrated embodiment.

6 and 9A-D, the anti-reverse mechanism 400 also includes a floating joint stopper 530 fixedly attached to the rib 200. The floating joint stopper 530 is disposed between the floating joint 500 and the second rib joint 230 and remains at a fixed position along the rib 200. The stopper 530 includes a bore 532 that extends through the stopper and receives the rib 200. The stopper 530 is fixed to the rib 200 using a conventional technique so as to fix the stopper 530 at a specific target position along the length of the rib 200. The stopper 530 may be fixed by mechanical or overmolding, which is a preferred method in this case. The stopper 530 is configured such that it restricts movement of the floating joint 500 in a direction toward the top notch 119.

It will be appreciated that when the umbrella is in the open position, the floating joint 500 advances along the rib 200 until it contacts the floating joint stop 530. The floating joint 500 combined with the floating joint stopper 530 prevents the rib 200 from reversing when under the force of strong wind. Reversal is prevented because the ribs cannot bend upwards, which is due to the blocking effect of the floating joint stop 530.

10A-D and 11-13 illustrate details of the tip 600 of the rib 200. The tip 600 includes a structure attached to the distal end of the rib 200. The tip 600 is defined by a hollow body 602 having a bore 603 that receives a distal end of the rib 200 and is fastened to the distal end. The tip 600 generally has a triangular wing shape and is defined by a first wing section 620 and a second wing section 630. The first wing section 620 and the second wing section 630 are outward and rearward from the main body 610. extend. Each of the wing sections 620, 630 has an angled leading edge 625, 635 and an angled tail edge 627, 637, respectively. In addition, as shown in FIG. 10D, the wing sections 620, 630 are angled relative to each other because the wing sections are not completely placed in the same plane. The tip 600 is constructed and designed so that it is angled to match the angle of the canopy when the canopy is in the open position.

11-13 illustrate another feature of the tip 600, wherein the bore 603 of the body 602 includes a biasing member 640, such as a spring. The spring 640 is disposed between the distal end of the rib 200 and a stopper 605 formed in the main body 602. The stopper 605 indicates the end of the bore 603. The bore 603 is designed to allow movement of the distal end of the rib 200 so as to allow the rib 200 and the umbrella to move in this regard between an open position and a closed position. Therefore, the spring 630 will store and release energy based on the way in which the ribs 200 act on it. Figure 12 shows the tip assembly in a closed / uncompressed state, and Figure 13 shows the tip assembly in an open / compressed state. In FIG. 13, the relationship between the umbrella cover and the tip when the umbrella is opened due to the compressed state of the spring 640 within the tip.

In an alternative embodiment, the tip may include a convex unit (structure) with a protruding portion that receives an opening formed in the distal end of a rib (e.g., an aluminum extrusion rib or a shaped steel rib) ( (Such as boring). Therefore, the coupling is formed by inserting the protruding portion of the tip into the opening (boring) of the rib. As in the above embodiment, a biasing member such as a spring may be placed in an opening (boring hole) formed in the rib and in contact with a protruding portion of the tip, which is similarly placed in the opening (boring hole) of the rib. )Inside.

FIG. 2 shows the umbrella 100 and details a single rib assembly in a half-open position, and FIG. 4 shows the umbrella and details a single rib assembly in a fully closed position.

Fig. 4 shows an umbrella 100 having a plurality of rib assemblies in a fully open position, and Fig. 5 shows an umbrella 100 having a plurality of rib assemblies in a fully closed position.

Although each part of the umbrella is necessary for its operation, the slider 150 is the part that opens and closes the umbrella. When the slider 150 is all the way down, the pillar 300 is folded flat against the shaft, and the umbrella is "closed", wherein the waterproof material and ribs are wrapped around the shaft. To open the umbrella, the user slides the slider 150 all the way to the top. The pillar 300 is extended to raise the rib 200 to which it is attached and spread the material (an umbrella cover) tightly on the rib 200.

19-21 illustrate an umbrella 700 according to another embodiment. The umbrella 700 is similar to the umbrella 100 and, therefore, the same elements are numbered the same. The umbrella 700 includes a shaft 110 and a slider 150 that slides along the shaft 110. As in the previous embodiment, the connection between the rib 200 and the slider 150 is facilitated by the pillar 300. Unlike the first embodiment, there is no anti-reverse pillar 400 between the pillar 300 and the rib 200. Alternatively, the umbrella 700 of FIGS. 19-21 includes a different anti-reverse strut mechanism 800.

In this embodiment, the anti-reverse strut mechanism 800 includes an anti-reverse strut 810 having a first end portion 812 and an opposite second end portion 814. The first end 812 is operatively coupled to a floating notch 815 that is movably disposed about the shaft 110. More precisely, the floating notch 815 is slidingly coupled to the shaft 110 and travels up and down along the shaft 110, much like the slider 150. The floating notch 815 is located between the slider 150 and the top notch 119.

The floating notch 815 may be similar to the top notch 119 in its configuration, and may be in the form of a ring-shaped member attached to and surrounding the shaft 110. Floating notch 815 is configured To receive anti-reversal pillars 810 and thus serve as attachment points for such pillars. The post 810 is attached to the shaft 110 by fitting into the floating notch 815 and can then be held by wire or other means. The floating notch 815 may be a thin circular nylon or plastic part with teeth around the edge.

The first end portion 812 of the anti-reverse post 810 is operatively coupled to the floating recess 815, and the second end portion 814 of the anti-reverse post 810 is operatively coupled to the rib 200.

Figures 19-21 show details of pillar 810. The anti-reverse post 810 is formed of a first parallel rod 820 and a second parallel rod 830. The first ends of the first parallel rod 820 and the second parallel rod 830 are coupled to the first joint 840 at a first end portion 812, and the second ends of the first parallel rod 820 and the second parallel rod 830 are at a second end portion 814 Coupled to the second joint 850. The first joint 840 may be one of a male joint and a female joint, and the second joint 850 may be one of a male joint and a female joint. For example, the first joint 840 may be in the form of a convex joint (a pair of stick convex joints), and the second joint 850 may be in the form of a concave joint (a pair of stick concave joints). A male joint (e.g., joint 840) is defined by a single protrusion (finger) 841, while a female joint (e.g., joint 850) is defined by a pair of spaced apart protrusions (fingers) 843, with space 845 Defined between the protrusions 843.

The first joint 840 is configured to be pivotably attached to the floating notch 815 and the second joint 850 is configured to be pivotally attached to the rib 200. With respect to the coupling between the joints 840, the protrusion 841 of the first joint 840 is received in a complementary space (slot) formed in the floating recess 815.

The second joint 850 is operatively coupled to a floating joint, such as the floating joint 500. As previously discussed, the floating joint 500 is slidingly coupled to the rib 200 and configured to mate with the second joint 850. 8A-D illustrate a floating joint 500. The floating joint 500 is defined by a main body 510 including a bore 512 formed in the main body 510 and representing a through-hole passing from one end of the main body 510 to the other end thereof. The floating joint 500 also includes a joint connector 520 in the form of a fin extending radially outward from the main body 510 (FIG. 8A). The connector 520 may be formed perpendicular to the main body 510. The connector 520 has an opening formed therein. Therefore, the connector 520 represents a male connector.

The anti-reverse post 810 is coupled to the rib 200 by inserting the connector 520 into the space 845 formed between the spaced-apart fingers (protrusions) 843 of the second end joint 413. As in another joint, a fastener or the like may be used to couple the connector 520 to the finger 843.

The rib 200 is received in and passes through the bore 512 (FIG. 8A), and the boring The size (diameter) of the hole 512 and the size (diameter) of the rib 200 are selected so that the floating joint 500 can move freely in the longitudinal direction along the length of the rib 200. This allows the floating joint 500 to travel freely up (toward the top notch 119) and down (toward the tip of the rib) along the rib 200 when the umbrella is opened and closed.

The pillar 300 passes in an open space formed between the first parallel rod 820 and the second parallel rod 830 formed in the anti-reverse pillar 810. This open space between the rods 820, 830 extends from the first joint 840 to the second joint 850 and accommodates the post 300 in all positions of the umbrella from the fully closed position to the fully folded position.

As in the first embodiment, the rib 200 of the umbrella 700 includes a floating joint stopper 530 that is fixedly attached to the rib 200. The floating joint stopper 530 is disposed between the floating joint 500 and the second rib joint 230 and remains at a fixed position along the rib 200. The stopper 530 includes a bore 532 that extends through the stopper 530 and receives the rib 200. The stopper 530 is fixed to the rib 200 using a conventional technique so as to fix the stopper 530 at a specific target position along the length of the rib 200. The stopper 530 may be fixed by mechanical or overmolding, which is a preferred method in this case. The stopper 530 is configured such that it restricts movement of the floating joint 500 in a direction toward the top notch 119. As in the first embodiment, the stopper 530 prevents the rib 200 from being reversed under pressure.

Therefore, in contrast to the first embodiment in which the anti-reverse mechanism is located between the pivotable pillar and the rib, the anti-reverse mechanism in the umbrella 700 is formed between the floating recess 815 and the floating joint 500 and is used to The floating recess is connected to the floating joint.

It will also be understood that the male / female type connection described herein is reversible because the portion described herein as containing a male connector may alternatively contain a female connector and, conversely, in this article The part described as containing a female connector may alternatively contain a male connector. For example, the floating joint 500 is shown as having a male connector 520; however, the floating joint 500 may alternatively be formed to have a pair of spaced fingers (flange) defined between the spaced fingers Space (female connector). Therefore, the distal end of the anti-reverse strut will be formed to have a male connector, as opposed to the female connector shown. The coupling is the same because the male connector is inserted into the space formed in the female connector. Similarly, the properties of other joints, such as the connection between a pillar and a fixed joint (eg, joint 230) can be reversed.

The slider locking feature of the present invention also provides several advantages over conventional designs. In particular, the locking insert provides a connection feature between the shaft segments that allows a method to lock the slider in place by not adding additional locking features that would undesirably increase the size of the slider. diameter.

22-32D illustrate an umbrella 900 according to another embodiment. Umbrella 900 is similar to other umbrellas, and therefore system elements are numbered the same. The umbrella 900 includes a shaft 110 and a slider 150 that slides along the shaft 110. There is also a top notch 910 along the axis 110 that slides along the axis 110. The top notch 910 is disposed above the slider 150 and there is a fixed notch, that is, a compression notch 920, which is disposed at the top of the shaft 110. Therefore, the top notch 910 is located between the compression notch 920 and the slider 150.

The compression notch 920 is pivotably connected to the first rib 930 at a first end portion of the first rib 930. A second end portion of the first rib portion 930 is pivotably connected to a second end portion of the compression arm portion 950. The first end of the compression arm portion 950 is pivotably connected to the top notch 910. 32A-D illustrate the first rib 930. The first rib 930 is an elongated structure having an asymmetrical property. The first end of the first rib 930 has a convex feature in the form of a single angled extension (finger) 931 that protrudes outward from the main body 932 of the first rib 930. As shown, the body 932 has a generally U-shaped configuration. A through hole is formed through the extension portion 931. The extension 931 is configured to mate with the compressible recess 920 (eg, a fastener may extend through a through-hole of the extension 931 to be coupled to both together). At the opposite second end, the first rib 930 has a concave feature in the form of a pair of spaced apart arm portions 933 that are parallel to each other. As shown in the top plan view of FIG. 32C, an open space 934 is formed between the two arm portions 933.

As shown in the side view of FIG. 32B, the extension portion 931 is angled downward in the first direction, and the two arm portions 933 are angled upward in the second direction. Along the two arms 933, there are two attachment points, that is, a first attachment point 935 and a second attachment point 936. The second end of the compression arm 950 is pivotably attached to the first rib 930 at the first attachment point 935 (eg, by using a fastener or the like).

As best shown in FIGS. 23 and 30C, a space 934 formed between the arms 933 allows the first pillar 960 to pass therethrough. A first end of the first pillar 960 is pivotably connected to the slider 150. The second end of the first post 960 is pivotably connected to the second rib joint 970. second The first end of the strut 980 is pivotally connected to the first rib 930 at the second attachment point 936 (eg, by using a fastener or the like). The second end of the second post 980 is pivotably connected to the second rib joint 970.

31A-D illustrate a second rib joint 970. The second rib joint 970 is formed by a substantially U-shaped body 971. As shown in the figure, the second rib joint 970 has a slight curvature along its length. The main body 971 has a first attachment point 972 and a second attachment point 973. The first attachment point 972 is located in the middle of both ends of the main body 971, and the second attachment point 973 is located at one end of the main body 971. The first post 960 is pivotably attached to the second attachment point 973 using a fastener or the like. The second pillar 980 is pivotably attached to the first attachment 972 at its end. The end of the main body 971 opposite the end containing the second attachment point 973 includes a shaped opening 974 guided into the hollow interior space. The illustrated opening 974 and the hollow interior space have a D shape.

The second rib joint 970 is also attached to the second rib 990 at its first end. More precisely, the first end of the second rib 990 is inserted into the hollow interior space via the opening 974. A second end of the second rib 990 is attached to a tip, such as the tip 1400 described herein. An exemplary tip 1400 is illustrated in Figures 27A-D. The tip 1400 includes a main body 1410 having a first end portion 1412 that is open and a second fin-shaped end portion 1414 that is closed.

The length of the first pillar 960 is greater than the length of the first rib portion 930 and the compression arm portion 950.

As is the case with the previous embodiment, the umbrella 800 includes an anti-reverse mechanism 1000. The anti-reverse mechanism 1000 operates in a manner similar to the anti-reverse mechanism described herein.

The anti-reverse mechanism 1000 includes an anti-reverse post 1010, an anti-reverse sliding joint 1100, and a sliding joint stopper 1200.

As best shown in FIGS. 30A-D, the anti-reverse strut 1010 is an elongated structure having a first end portion 1012 and an opposite second end portion 1014. 30A-D best illustrate the shape and structure of the anti-reverse strut 1010. In some aspects, the anti-reverse strut 1010 is similar to bone. As shown in the figure, the anti-reverse strut 1010 is asymmetric, but instead has a central inflection point 1011 which defines a first strut portion 1020 that extends to the first end portion 1012 and Terminated at the first end portion 1012; and a second pillar portion 1030 that extends to the second end portion 1014 and terminates at the second end portion 1014. As will be described in more detail herein, according to the end view (Figure 30D), due to the curvature incorporated in each of the first pillar portion 1020 and the second pillar portion 1030, the anti-reverse pillar 1010 has a substantially H shape.

As viewed from the side view of FIG. 30B, the anti-reverse strut 1010 is defined by a first face 1013 and an opposite second face 1015. As can be seen in the drawings and will be described in more detail below, the first pillar portion 1020 has a concave shape along the first face 1013 and a convex shape along the second face 1015, and, conversely, the second pillar portion 1030 It has a convex shape along the first surface 1013 and a concave shape along the second surface 1015.

As can be seen in the plan view of FIG. 30C, each of the first end portion 1012 and the second end portion 1014 has a U-shaped notch (opening) 1040 formed therein. The formation of the U-shaped notch 1040 defines a first finger extension 1050 and a second finger extension 1052 that are spaced apart and parallel to each other. The free ends of the first finger extension 1050 and the second finger extension 1052 have an axially aligned opening 1060 formed therein for receiving a fastener or the like to turn the anti-reverse post 1010. Coupling to another structure, as described herein.

As best shown in the perspective view of FIG. 30A, the recessed section of each of the first strut portion 1020 and the second strut portion 1030 defines a slot 1018, which is defined by a pair of opposing upright side walls 1019. Due to the shape of the anti-reversal pillar 1010, the depth of the groove formed along the first face 1013 of the first pillar portion 1020 and the depth of the groove formed along the second face 1015 of the second pillar portion 1030 are toward the center inflection point 1011 Gradually decreases in direction. At the central inflection point 1011, each of the first surface 1013 and the second surface 1015 transitions between a concave shape groove at one end and a convex shape surface at the other end.

The profile of the upright side wall 1019 is the same in the first pillar portion 1020 as it is in the second pillar portion 1030. In other words, the height of the upright side wall 1019 is the same in the two pillar portions 1020, 1030, but faces opposite directions, as described herein.

The first pillar portion 1020 is attached to the second pillar 980. More specifically, an AIS (anti-reverse strut) joint 1070 is provided along the position of the second strut 980 and is configured to fit to the first strut portion 1020. In particular, the AIS joint 1070 may have a protrusion or flange (marked portion) that is inserted into the space 1040 between the arm portions 1050, 1052. The fastener passes through the opening 1060 and through the opening in the protrusion of the AIS joint 1070 to pivotally couple the two together. The AIS connector 1070 may be located at an intermediate position between the ends of the second pillar 980 and Keep at the selected fixed position. As described below, the slot 1018 of the first pillar portion 1020 is sized and shaped to receive the second pillar 980 when the umbrella is folded and assumes a closed position.

The anti-reverse mechanism 1000 also includes a floating (sliding) joint 1100, which is slidably coupled to the second rib 990, and is configured to cooperate with the second pillar portion 1030 of the anti-reverse pillar 1010. 28A-D illustrate a floating joint 1100 that is configured such that it can slide along the second rib 990. The floating joint 1100 has a main body 1110 including a bore 1112 formed in the main body 1110 and representing a through hole passing from one end of the main body 1110 to the other end thereof. The floating joint 1100 also includes joint connectors 1120 in the form of a pair of spaced fins that extend radially outward from the main body 1110. The connector 1120 may be formed perpendicular to the main body 1110. The connector 1120 has an opening formed therein. Therefore, the connector 1120 represents a male joint and is located below the bore 1112 so as not to interfere with it.

The second part 1030 of the anti-reverse post 1010 is fitted to the sliding joint 1100 by inserting a joint connector (two fins) 1120 internally between the arms 1050, 1052 of the second post part 1030 so as to pass therethrough The openings formed are aligned axially. Fasteners or the like are then passed through the holes to allow attachment therebetween.

As shown in FIG. 24, when the anti-reversal pillar 1010 is attached to the surrounding components in the manner described herein, the convex first surface 1013 of the second pillar portion 1030 and the concave first surface 1013 of the first pillar portion 1020 Facing the second rib 990. Similarly, the concave second surface 1015 of the second pillar portion 1030 and the convex second surface 1015 of the first pillar portion 1020 face the second pillar 980.

Therefore, the anti-reverse strut 1010 is coupled to the second rib 990 by being coupled to the sliding joint 1100.

It will be appreciated that in another embodiment, the floating joint may be a convex portion including a male connector (part 1120); however, it is positioned inside the second rib 990 such that the floating joint is on the second rib 990 (for example, aluminum extrusion ribs or shaped steel ribs) moves freely inside the hollow inside. The rib 990 may thus have a linear slot formed therein, with the connector 1120 passing through the linear slot. The operation of the floating joint is otherwise the same. Therefore, in this alternative embodiment, the "floating action" of the floating joint occurs internally in the second rib 990, as opposed to what happens on the outside of the second rib 990 in the illustrated embodiment.

Referring to FIGS. 22 and 29A-D, the anti-reverse mechanism 1000 also includes a floating joint stop Piece 1200 which is fixedly attached to the second rib 990 at a selected fixed position. The floating joint stopper 1200 is disposed between the floating joint 1100 and the second rib joint 970 and remains at a fixed position along the rib 200. The stopper 1200 includes a bore 1210 that extends through the stopper 1200 and receives the second rib 990. The stopper 1200 is fixed to the second rib 990 using a conventional technique so as to fix the stopper 1200 at a specific target position along the length of the second rib 990. The stopper 1200 may be fixed by mechanical or overmolding, which is a preferred method in this case. The stopper 1200 is configured such that it restricts movement of the floating joint 1100 in a direction toward the second rib joint 970.

It will be appreciated that when the umbrella is in the open position, the floating joint 1100 travels along the second rib 990 until it contacts the floating joint stop 1200. The floating joint 1100 combined with the floating joint stopper 1200 prevents the second rib 990 from being reversed when under the force of strong wind. Reversal is prevented because the ribs cannot bend upwards due to the blocking effect of the floating joint stop 1200.

As described herein, the shape of the anti-reverse strut 1010 is designed to facilitate folding of the umbrella into a small footprint (ie, a thin profile), as shown in FIG. 25. More precisely, and as best shown in FIG. 25, the anti-reverse strut 1010 is designed so that when the umbrella 900 is folded to its fully folded position, the anti-reverse strut 1010 abuts against the second rib 990 and Between the second pillars 980, thereby allowing for a more compact assembly when folded. As shown in FIG. 25, the groove 1018 of the second pillar portion 1030 receives the distal end portion (the portion between the tip 1400 and the joint stopper 1200) of the second rib 990 in a nest manner, and similarly, the first pillar The slot portion 1018 of the portion 1020 receives the second pillar 980 in a nested manner. This nesting of the second rib 990 and the second pillar 980 reduces the total occupied area of the umbrella 900 in the fully folded position of FIG. 25.

The rib 1600 also includes a second rib joint 1525 (which may be the same as the joint 230) that is disposed along the length of the rib 1600. The second rib joint 1525 may be fixedly attached to the rib 1600 at a specific position of the rib 1600. The second rib joint 1525 may thus be in the form of a hollow structure that receives the rib 1600 and is fixedly attached to the rib 1600 so that during use, the second rib joint 1525 does not move but remains in a fixed position. The second rib joint 1525 has a connector portion 1527 (FIG. 38) in the form of a fin (projection) extending radially outward thereof. The connector portion 1527 may thus be formed perpendicular to the main body of the second rib joint 1525. The connector portion 1527 includes an opening formed therethrough.

The connector portion 1527 is sized and configured to be placed in an open space, wherein the open space is defined between the pair of spaced apart fingers of the second post joint 1520. When inserted into the open space, the opening formed in the connector portion 1527 is axially aligned with the opening in the finger so as to allow the passage of a fastener (such as a pin or a rivet or a wire) through which the second pillar is passed The joint 1520 may be pivotally attached to the rib 1600 (and therefore, the pillar 1500 may be pivotally attached to the rib 1600).

As in the case of the previous embodiments described herein, the umbrella 1300 has an anti-reverse mechanism. The anti-reverse mechanism includes an anti-reverse post 1010, an anti-reverse sliding joint 1100, and a sliding joint stopper 530.

The anti-reverse post 1010 used in the umbrella 1300 has been described in great detail above and is shown in several drawings including FIGS. 30A-D. As is the case with the previous embodiment, one end of the anti-reverse strut 1010 is pivotably coupled to the strut 1500, and the other end is pivotally coupled to the rib 1600 through a sliding joint 1100. As previously mentioned and according to some aspects, the anti-reverse strut 1010 is similar to bone. As shown in the figure, the anti-reversal pillar 1010 is asymmetric, but instead has a central inflection point 1011 which defines a first pillar portion 1020 that extends to the first end and is at Terminate at the first end; and a second pillar portion 1030 that extends to the second end and terminates at the second end. As will be described in more detail herein, according to the end view (FIG. 30D), attributed to each of the first pillar portion 1020 and the second pillar portion 1030 is incorporated. Among the curvatures, the anti-reverse strut 1010 has a substantially H shape.

The first pillar portion 1020 is attached to the pillar 1500.

The anti-reverse mechanism also includes a floating (sliding) joint 1100 that is slidingly coupled to the rib 1600 and is configured to cooperate with the second pillar portion 1030 of the anti-reverse pillar 1010. 28A-D illustrate the floating joint 1100, and the connection between the second portion 1030 of the anti-reverse strut 1010 and the sliding joint 1100 is described herein.

The anti-reverse mechanism also includes a floating joint stopper 530 fixedly attached to the rib 1600. The floating joint stopper 530 is disposed between the floating joint 1100 and the second rib joint 1525 and remains at a fixed position along the rib 1600. The stopper 530 includes a bore 532 that extends through the stopper 530 and receives the rib 200. The stopper 530 is fixed to the rib 200 using a conventional technique so as to fix the stopper 530 at a specific target position along the length of the rib 200. The stopper 530 may be fixed by mechanical or overmolding, which is a preferred method in this case. The stopper 530 is configured such that it restricts movement of the floating joint 1100 in a direction toward the top notch 1320.

It will be appreciated that when the umbrella is in the open position, the floating joint 1100 travels along the rib 1600 until it contacts the floating joint stop 530. The floating joint 1100 combined with the floating joint stopper 530 prevents the rib 1600 from reversing when under the force of strong wind. Reversal is prevented because the ribs cannot bend upwards due to the blocking effect of the floating joint stop 530.

Umbrella 1300 also includes a tip 600 or 1400, which is described herein and illustrated in Figures 10A-D and 11-13 and Figures 27A-D.

The anti-reverse post 1010 is designed such that when the umbrella 1300 is folded to its fully folded position, the anti-reverse post 1010 abuts between the rib 1600 and the post 1500, thereby allowing a more compact assembly when folded. The groove of the first pillar portion 1020 receives the distal end portion of the rib 1400 (the portion between the tip 1400 and the joint stopper 530) in a nested manner, and similarly, the groove portion of the second pillar portion 1030 is a nested manner. Receive pillar 1500. This nesting of the ribs 1400 and the pillars 1500 reduces the total occupied area of the umbrella 1300 in the fully folded position of FIG. 35.
