Description

Detailed Description of the Invention (Field of Application on L-leaf) The present invention has a shutter frame that forms a moving space for door panels and a door bag frame that configures a door pocket adjacent to the shutter frame, This invention relates to an electric storm door i that uses a motor to perform operations such as pulling it out from a door pocket and storing it in the door pocket.

(Prior Art) A conventional electric storm door has a shutter frame that forms a movement space for the door plate, and a door bag frame that configures a door bag adjacent to the shutter frame. The shutter frame is provided with a rail for guiding the door panels on the lower frame of -L, so that the plurality of door panels run smoothly along this rail. Furthermore, adjacent door panels are connected by connecting metal fittings, and when the door panels are moved in and out of the door pocket, the following door panels can follow the movement of the first door panel. ! A motor and a motor are installed at the rear of the door, and in order to transmit the driving force of this motor to the door panel, a motor and a chain are also used. Although the door boards are arranged in series within the shutter frame, they are stored in parallel in the door pocket.

Therefore, the force-receiving end of the connecting fitting is adapted to slide along the groove of the door plate from one end of the door plate to the other end when the door plate is stored in the door bag.

(Problem to be solved by the invention) Conventional electric storm doors C are connected in a daisy chain from the first door plate to the last door plate so that the desired j. It is easy to leave only the panel in the desired position, or replace only the damaged door panel.In case of an emergency, you can manually Even in L2, the door plate can only be opened in one direction, so it is not possible to secure the m ffi [cr] quickly. 3. (Means for Solving the Problems) The present invention provides a means for solving the problems. In order to solve the above problem, we have a shutter frame that forms a moving space for the door board and a door box frame that forms a door pocket adjacent to this rain door frame, and it is possible to pull out a plurality of door boards from the door pocket or store them in the door pocket. In the electric storm door which performs the operation using a motor, a door plate guide block provided at a corner of the door bag, a first endless belt provided reciprocatingly in a door plate running groove of the shutter frame, and the The first endless belt includes a second endless belt that is reciprocally movable for moving a door plate provided over the entire bottom surface of the door pocket, and a driving means that drives these endless belts in the same direction,
The second endless bell F is such that its upper running surfaces are adjacent to each other at almost the same height so that the door plate can be passed between both belts at the doorway of the door compartment, and the bottom surface of each door plate is A caster holder that has two casters installed near both ends in the longitudinal axis direction and an end that can freely move in and out of the door plate, and elastically holds the wheels of each caster obliquely with respect to the longitudinal axis direction of the door plate. An electric storm door is provided, characterized in that it includes a spring member attached to the electric storm door.

(Function) In the electric storm door described above, when closing the storm door, the driving means is first activated to pull out the door plate stored in the door pocket. This causes the first and second endless belts to move in the same direction, and! :Mona-, the door plate closest to the entrance of the lower door bag is sent out from the exit by the second belt. Thereafter, the door panel is transferred to the first belt and further pulled out into the space of the shutter frame by the first belt.

The casters of the next door plate, which was housed adjacent to the above door plate, are angled by the action of the spring member, and the second belt is rotated.
Moving in the direction of the non-exit, these angled casters and the guide tab [ ] on the exit 1 side Ea move the door board to the first
It moves laterally so as to align with the direction of movement of the belt, and comes to be adjacent to the inner wall of the door pocket. The inner wall restores the angle of the caster to the original position, and the caster is moved linearly along the direction of movement on the second belt and sent out from the outlet. Furthermore, the next door panel is moved in the same way and sent out from the door pocket.

On the other hand, when storing the door plate in the door pocket, the first and second endless belts move in the opposite direction to the above case and in the same direction, and as a result, the door plate closest to the entrance of the door pocket moves in the same direction. It is fed from the entrance by the first belt, handed over to the first belt by the second belt, and moved inside the door compartment. The first belt and the second belt have different belt moving speeds, and are adjusted so that the first belt is faster than the second belt. As a result, when the door plate near the door pocket moves to the first belt in the door pocket, the distance between it and the door plate on the second belt increases, making it easier to store the door plate in the door pocket.

When the door plate near the door pocket moves on the first endless belt and the tip of the door plate hits the guide block at the back of the door pocket, the guide block causes the tip of the door plate to turn slightly sideways.

As a result, the angle of the casters at the front of the door plate changes, and the front part of the door plate moves further back on the belt.

As the door plate moves diagonally forward, the angle of the casters at the rear of the door plate also changes. By means of the angled casters and the guide block, the door plate is moved laterally in parallel and stored in the innermost part of the door compartment. Thereafter, the next door panel is similarly moved and arranged in parallel so as to be adjacent to the previous door panel.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the shutter is composed of a plurality of door panels l. The movement space is defined by the shutter frame 2. A door pocket: ( is provided adjacent to this shutter frame 2. This door pocket 3 occupies a closed rectangular parallelepiped space.
It is formed by.

The vertical and horizontal lengths of this rectangular parallelepiped space are at least larger than the vertical and horizontal lengths of the door panel 1, and its width is larger than the length corresponding to the thickness of a plurality of door panels. Furthermore, an entrance 5 for the door plate 1 is formed at one corner of the rectangular parallelepiped door pocket 3. The corners on both sides of the corner where this entrance/exit 5 is are located.
A guide block 6.7.8.9 is attached to the two lower ends. The guide blocks 6.7 and 8.9 are fixed to the door case frame 4 so as to be located diagonally on the rectangular bottom and top surfaces of the door case 3, respectively. The guide blocks 6.7.8.9 each have a guide surface that is oblique to the side of the door pocket.

An endless belt 10 is provided on the bottom surface of the door pocket 3, and this endless belt 10 is wound between a driving roller 11 and a driven roller 12 that are rotatably supported by the door pocket frame 4. With this endless belt 10, the door plate inside the door pocket is moved as shown by the arrow A.
, B.

On the other hand, as shown in FIGS. 2 and 3, the upper and lower frames 13 and 14 of the shutter frame 4 are provided with grooves 15 and I6 for guiding the door plate. The upper and lower ends of the door plate 1 are fitted into these grooves 15 and 16. Furthermore, the lower frame 14
An endless belt 17 is movably attached to the groove 16. This endless belt 17, as shown in FIG.
A drive roller 18 rotatably supported at both ends of the shutter frame 4
and the driven roller 19.

The width of this endless belt 17 is equal to the width of the door plate, and the door plate moves together with the belt 17 within the shutter frame in either direction of arrows Δ and B due to the contact friction between the endless belt 17 and the door plate.

Endless belts 17, 11 running in the grooves of the shutter frame: The endless belts 10 inside the door pocket are placed against each other so that their upper running surfaces are at the same height at the entrance 5 of the door pocket.

Referring again to FIG. 1, a driving sprocket 20 is connected to the driving roller 11, and a driving sprocket 21 is connected to the driving roller 18. A chain 22 is stretched between these drive subs 2.21, and this chain 22 is further connected to a motor connection sprocket 25 via a guide sprocket 23.24.
It is also built on This motor connection sub-hooket 2
5. is attached to the rotating shaft of the motor 26. With this structure, the rotation of the motor is simultaneously transmitted to the endless belts 10 and 17, and both belts move in the same direction.

The speeds of the first and second endless belts (10.17) are not exactly the same, and by changing the gears of the sprockets 20 and 21, the speed of the belt 10 is usually made faster.

This is useful for eliminating contact between the door panels and ensuring smooth operation when storing the door panels in the door pocket.

As shown in FIGS. 3 to 6, casters 27 and 28 are attached to the lower end portion of each door plate. Each caster is rotatably attached to a caster holder 29 by a fixed pin 31. The casters are installed near both ends in the longitudinal axis direction of the bottom of the door plate, spaced apart from each other. : are each provided with a corner block 32. This corner block 32 has rollers at both ends, so that this corner block serves to soften the impact between the door plate and the guide block when they come into contact with each other in the door pocket. Fifth
As shown in the figure, the caster] Ruder 29
As will be described later, a mechanism is provided for changing the direction of the caster's λl (wheel).With this mechanism, the wheels of each caster are normally aligned in the longitudinal axis direction of the door plate, as shown in Figure 4. It has an angle of 1° to

FIG. 5 is an exploded illustration of the mounting structure of the casters to the door plate. Caster 27 is caster holder 29
The caster holder 29 is inserted into four parts 33 provided at the lower end of the door plate. The caster holder 29 is a cylindrical member with a conical tip, into which a caster support 36 is inserted via an adjustment plate 34 and a cylindrical bearing 35.

This caster support 36 also has a conical tip, similar to the Toyaster holder. This conical tip portion is adapted to fit into a conical recess on the bottom surface of the adjustment plate 34 when the caster holder 29 is mounted. An adjustment screw 37 is screwably attached to the conical portion at the tip of the caster holder 29, and the tip of this screw penetrates into the inside of the caster holder.
It is in contact with the outer surface of the adjustment plate 34.

The caster support body 36 is composed of a cylindrical portion having large, medium, and small diameters, and the conical tip portion. The cylindrical bearing 35 is fitted into this small-diameter cylindrical portion, and the adjustment plate 34 is placed over it.

A slit is formed in the medium diameter and large diameter cylindrical parts, and the central part of the caster bracket 39 is attached thereto.
Casters are attached by fixed pins 31. This fixing bin 31 also fixes the caster bracket 39 to the caster support 136 at the same time.
The caster bracket (39), the caster support 36, and the casters move together.

A bracket tab 40 and a swing roller 41 are attached to both ends of this special file bracket, respectively. This bracket block! 10 serves as a bridge when the door plate is passed between the belt 10 in the door pocket and the belt 17 in the shutter frame, and as a result, the relatively small caster can be caught between the two belts. When the door plate moves, the movement of the door plate stops and U'L+Mauko.
It works to relieve friction with the inner wall surface of the door pocket, the inner wall surface of the shutter frame, and the side surfaces of other adjacent door panels within the door pocket.

The caster holder 29 is fitted into a mounting plate 42 having an opening in the center, and its upper half is in the recess 33 of the door plate, and its lower half is attached to the bottom of the door plate with blind rivets or the like, with the lower half protruding outward. Fixed. As a result, as shown in FIGS. 7 and 8, only the caster supporting portion of the caster holder is attached to this mounting plate 4.
It protrudes downward from 2 (upward in Figure 7).

Referring to FIGS. 5 and 6, the lower end portion of the door plate is provided with a lower stile extending in the longitudinal direction on both sides thereof. Two large notches 44 and a small window 45 are formed in one of the stiles at the positions where the caster holders are attached, adjacent to the corner blocks at both ends of the door plate.

On the other hand, a spring bracket 46 is attached to the caster bracket 39. This spring bracket 46 is a box-shaped member, and a plate-shaped spring 47 with both ends open in a V-shape is attached inside the spring bracket 46. Moreover, two protrusions 48 are provided on the outside thereof. As shown in FIG. 9, the caster bracket 39 has surfaces at both ends that are slightly inclined inward. The spring 47 is in constant contact with this inclined surface and presses it in the opposite direction.

The protrusion 48 of the spring bracket is attached so as to protrude laterally from the small window 45 of the lower sill when the caster holder is attached to the door plate. The spring bracket 46 can be moved left and right by gripping the protrusion 48, thereby easily changing the contact points between the two tips of the spring 47 and the slope of the caster bracket 39.

Under normal conditions, the position of this spring bracket 46 is slightly shifted to one side with respect to the position of the caster bracket, so that the caster bracket is inclined to one side. (See FIG. 9) At this time, the ends of the caster brackets are designed not to protrude outside through one of the large notches 44 of the lower gusset. If the position of the spring bracket 46 is shifted to the opposite side, the opposite end of the caster bracket will not protrude from the other notch 44.

In either case, such a structure allows the wheels of the casters to form an angle with the longitudinal axis of the door panel. On the other hand, when a sufficient force is applied to push the caster bracket back into the stile, for example in the case of the door plate IA shown in FIG. 10, the wheels of the casters become parallel to the longitudinal axis of the door plate.

Next, the operation of the electric storm door using the door plate of the present invention that holds the casters so that the direction of the wheels of the casters can be changed will be explained.

Referring to FIG. 10, there is shown an explanatory diagram of the operation of the electric storm door using a sectional view of the lower end portion of the door plate. In this figure, only the swing roller 41, caster bracket 39 and caster holder 29 are shown in a simplified form.

In A of Fig. 10, when pulling out multiple door panels stored in the door pocket, the belt 1 in the shutter frame must be removed. Toto'A
The inner belt IO is driven by a motor so as to move together in the direction of the arrow.

The door panel IA closest to the exit 5 of the door pocket is regulated by the inner wall of the door pocket, and its casters 27 and 28 are both oriented parallel to the longitudinal axis of the door panel.

The door plate IA is sent in the direction of the arrow 1 by the bell 1-10 and is delivered to the belt 17 on the extension line of the door plate IA at the exit 5 of the door pocket. At this time, as described above, the bracket block 40 of the caster bracket serves as an Iff between both belts. The casters are attached to the caster holder so that they can rotate freely, but in this case, the force exerted on the casters by the door plate's own weight is much greater than the rotational force transmitted to the casters by the belt. The casters hardly rotate and move as the belt moves.

As shown in FIG. 10, the caster brackets on only one side of the door plate IB adjacent to the door plate IA protrude outward when the door plate IA passes.

As a result, the direction of the wheels of the casters 27 on the back side of the door bag becomes oblique with respect to the longitudinal axis direction of the door plate. The door plate IB is also sent in the direction of the arrow by the belt 10, but its tip is immediately stopped by the guide surface 7A of the guide block 7. Therefore, the door plate IB cannot move forward despite the movement of the belt, and only the casters 27 and 28 start rotating on the spot.

Eventually, as shown in Figure 10C, the door plate I A (7)
When the rear end comes out from the door pocket exit, the wheels of the door pocket exit side casters 28 of the door board IB also become oblique with respect to the longitudinal axis direction of the door board, similar to the door pocket back side casters 27. As a result, the rotation of the casters and the movement of the belt combine to make the door plate IB
is translated in parallel to the upper right direction along the guide surface 7Δ. Thereafter, the door plate IB is sent out into the shutter frame from the door bag exit 5 following the door plate IA, as shown in the 10th diagram.

Similarly, the door plate IC is also moved diagonally upward and to the right in parallel to follow the door plate IB. (See Figure 10, E) After that, this door plate IC is also sent out from the door bag exit 5 into the shutter frame, following the door plate IB.
, IB, and IC in the door pocket 3, the operation is substantially the opposite of the above-mentioned operation. Zunawara, belt 1 inside the shutter frame
7 and the belt lO in the door pocket are both driven by a motor to move in the direction a. As shown in FIG. 10F, the first door plate IC] closest to population 5 of the door pocket is sent by the belt 17 within the shutter frame in the direction of the person [,
, I 5 to the belt 10. This door plate IC is moved within the door pocket by the belt 10, and its tip abuts against the guide surface ()Δ of the guide block 6. At this time, as mentioned above, the corner blocks of the door plate work to soften the contact with the guide block.

The tip of the rear door plate IC is the guide slope 6Δ of the guide block 6.
Move diagonally downward to the left along the . As a result, the door plate IC
moves away from the top wall of the door pocket, and the restrictions on the caster brackets are relaxed. Therefore, in addition to the wheels of the rear caster 27,
The wheels of the population side caster 28 also change their direction, and the 1st O
Shown at G in the figure. become a state. As mentioned above, Toita I
The forward movement of C is blocked by the guide block 6, so that the casters 27, 28 will rotate in place. As a result, the rotation of the casters and the movement of the belt combine to move the door plate IB in parallel to the lower left along the guide surface 6A.

The subsequent door plate IB is similarly moved by the bell (10) in the door pocket and placed parallel to and adjacent to the door plate IC. Subsequently, the last door plate I△ is also fed into the door pocket from the passenger 5 by the belt 17, and further advanced in the direction of arrow a by the belt 10, and its tip abuts against the guide surface 6A.

At time 2, the motor operation stops and the storage operation is completed. The speed of both belts is adjusted so that the belt 10 inside the door pocket moves faster than the belt 17 inside the shutter frame, so the door plate IC moves faster than the belt 17 inside the shutter frame.
When moving to -C, the door plate IB gradually separates from -C, and the storage operation of the door plate is continuously and smoothly performed without colliding with each other.

FIG. 11 shows a modification of the guide blocks 6, 7, 8, and 9 used at the corners of the door pocket shown in FIG. 58.
It has a rare fish number of 59.

The guide blocks 56 and 57 provided on the bottom of the door pocket each have a guide slope provided only in the portion near the entrance/exit of the door pocket. Therefore, when such a guide block ``]tsuku'' is used, the door plate will move in parallel in the horizontal direction within the door compartment except around the entrance/exit L. A guide slope, or tapered surface 57A15713, is formed in each section.This is because when a door plate is fed out from the door bag, as the door plate closest to the exit is fed out, the rear end of the adjacent door plate comes into contact with this door plate. This is to ensure that the movement is not obstructed.

This will be explained as follows with reference to FIG.

That is, in A of FIG. 10, when the door plate IA near the exit is sent out, only the rear caster 27 of the two casters of the adjacent door plate IB changes its direction first (see B of FIG. 10). The back side portion of the door plate IB is pressed toward the door plate IA that is being sent out, and comes to interfere with the sending out operation. Therefore, by providing such a tapered surface 57B, the adjacent door plate IB
This kind of movement of the inner part of the body is prevented.

Although the guide block 59 is formed with only one guide surface, the upper part of the door plate normally follows the door plate a little later than the lower part of the door plate where the movement of the belt is directly transmitted, so there is only one guide surface. One is enough. However, the guide surface may be formed in exactly the same way as the block 57.

Further, the guide block 58 is wedge-shaped, and its tip extends obliquely downward toward the doorway 5. With this shape, when the door plate is sent out from the exit 5, as the lower part of the door plate advances toward the exit 5 along the guide surface of the guide block 56, the upper part of the door plate also collapses toward the back of the door bag. He quickly gets up and heads toward the exit. Therefore, when pulling out the door plate from the door pocket, the upper part of the door plate does not get stuck and prevent smooth movement.

Note that in the present invention, the operation of the motor can be started by a switch installed indoors, similar to conventional electric storm doors. Furthermore, it can be stopped using this switch, but for example, a reed switch is provided at the end of the shutter frame on the side opposite to the door pocket, and on the inner wall opposite to the doorway inside the door pocket, and the reed switch and the motor can be stopped. The operations may be linked.

In the electric storm door of the present invention, in order to stop the door plate at a desired position, for example, when storing the door plate in the door pouch, hold the last door plate with your hand and feed the belt 17 emptyly to stop only the other door plates. You can store it in a door bag. After the motor is stopped, the door panel remaining within the shutter frame may be manually moved to a desired position. Furthermore, when pulling out the door plate from the door pocket, the first door plate may be manually stopped at a desired position to stop the operation of the motor. As a result, only a portion of the door panel is pulled out from the door pocket.

Furthermore, according to the invention, the moving speeds of belts 10 and 17 may be the same or different. belts 10 and 17
If there is a difference in the moving speeds of the belts 10 and 17, it is preferable to make the speed of the belt 10 faster than the speed of the belt 17 when storing the door plate in the door pocket, as shown in the embodiment. This results in various additional advantages. That is, when storing door panels with high sealability between door panels in a door pocket, the door panels can be easily separated from each other within the door pocket. Further, when the door plate is pulled out from the door pocket, a gap is created between the door plates, so that the door plate can be fixed at a desired position within the shutter frame by inserting a hand into the gap.

(Effects of the Invention) According to the present invention, the door panels are not connected in a row but can be separated from each other, making it easy to leave only the desired door panel in the desired position or replace only the damaged door panel. . Additionally, in the event of an emergency evacuation, the door panels can be opened manually in any direction, making it possible to quickly secure an evacuation exit. Even if the motor fails or the door plate gets caught in the door bag, the chained door plates will not prevent escape to the outdoors, which is extremely advantageous in terms of safety.
