Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe as described in the preamble part of claim 1 and particularly to a shoe for sports.

[0002]

2. Description of the Prior Art Shoes of the type described in the preamble of claim 1 are of various constructions known to the person skilled in the art, in particular constructions in the form of relatively sports shoes. For example, race shoes, tennis shoes,
These include basketball boots, trekking and hiking shoes, military shoes and cross-country shoes. In such a case, the shoe is generally of the type having a relatively flexible upper and a rear hard heel cap, the upper being adjustable relative to each other in the instep portion of the foot. It has two flap-like parts. Such a shoe has a rotary tensioner as a central fastener, which is guided by a flexure guide attached to a flap-like portion of the upper or a strap attached to the upper. A pull cord, which is used to pull or loosen the flap-like portion of the instep together,
It is wound around the string pulley and unwound from the string pulley. A rotary tensioner of this type is described in European patent EP-A-4.
12290. The above-mentioned shoes known to the person skilled in the art show that the fastener housing, together with the fastening elements of the rotary tensioner supported on it, is generally arranged in the instep part of the instep, in particular provided on it. Placed on the tongue. The two flap-like parts of the upper, which are pulled together with each other, or the lateral straps attached to it, are arranged on both sides of the upper part.

[0003]

The object of the present invention is to improve a shoe of the type described in the preamble part of claim 1 of the appended claims, which shoe, on the one hand,
It is characterized in that the mounting part of the rotary tensioner can be manufactured relatively easily and easily, while on the other hand it can be mounted particularly well on the foot.

[0004]

This object is achieved by an invention combining the features described in the characterizing part of claim 1 of the present invention.

According to the invention, a flexible upper part having two flap-like parts 1a, 1b which can be clamped against one another at the upper part of the foot and a rear rigid heel cap 4 1, a fastener housing 6, a cord pulley 7 rotatably mounted in the fastener housing 6 and drivable therein, a rotation actuating knob 8 and a single pull cord 9; 9 is guided by a cord bending guide portion 10 arranged on the flap-shaped portions 1a, 1b of the instep portion 1, and in order to repeatedly pull and release the flap-shaped portions 1a, 1b of the instep portion together, the cord pulley 9 In a shoe having a rotary tensioner 5 wound around and unwound from 7, carried by the instep 1, the rotary tensioner 5 is housed in the central part on the rear side. A heel cap 4 having an upwardly projecting extension 13 configured as a fastener support for securing and fixing, and tightening of the instep portion 3 extending from the rotary tensioner 5 carried by the heel cap 4. The pull string loop 9b extending beyond the portion 11.

[0006]

The first feature that is fundamental to the present invention is the heel cap. Such heel caps are made slightly wider by very simple means compared to the known constructions. That is, such a heel cap has an upwardly projecting extension in the rear central part (ie, substantially symmetrically with respect to the vertical center plane in the longitudinal direction of the shoe), which extension is rotationally tensioned. Configured as a support device for the clamp, it houses and secures the rotary pull clamp. Thus, the heel cap has a structure which is substantially identical to that of known shoe heel caps, the heel cap being merely wide enough in the rear central part and an additional flap projecting sufficiently upwards. Has an extended portion. Thus, this heel cap constructed in accordance with the present invention not only functions for the practical purpose of stiffening the heel of the instep of a shoe, but it also accommodates a rotary tensioner in a favorable condition. It also functions to hold it securely. The extension of the heel cap, which serves as a support for the fastener, is very easily, in particular integrally, attached to the rear central part of the heel cap. For example, suppose that the heel cap is molded of a corresponding synthetic resin. The extension of the heel cap, which then functions as a support for the fastener, is molded over the heel cap very easily and preferably during the manufacture of the heel cap.

In the arrangement according to the invention, in contrast to the known shoes mentioned above, the rotary tensioner is attached to the heel part of the shoe or to the upper part of the shoe and, by judicious combination, enables the use of a single pull cord. The formed loop extends beyond the rotary tensioner carried on the heel cap, passes around the foot, and extends beyond the tightening region of the instep portion. Thus, in a shoe constructed according to the present invention,
Not only is a secure tightening ensured on the instep, but the instep is pulled together in a very favorable condition between the instep and the heel, especially below the ankle. Or it can be tightened. This allows the foot to be attached to the shoe in a particularly favorable and secure manner.

In accordance with a preferred embodiment of the present invention, a recess is provided for receiving a fastener, the recess being at the extension of the heel cap, the longitudinal axis of the shoe or the vertical center plane of the shoe. With respect to, the center-aligned fastener housing of the rotary tensioner is received and mounted to form a lock in this recess. Such recesses are formed at the same time as the heel cap is manufactured and molded, for example by a relatively simple and suitable matching molding or stamping tool. Thus, the rotary tensioner is not only easily attached to the extension of the heel cap,
It can be formed or integrated into this extension.

In the above description, assuming at least the heel cap is covered, in the usual manner, by the skin used for the outer material, ie, the upper, the rotary tensioner is located within the fastener receiving recess. It is provided at a predetermined depth, which is set such that the rotary actuating knob with the relatively shallow outer curve of the fastener projects outwardly and beyond the outer material. A shoe of particularly attractive construction is thus obtained.

In many shoes, especially in sports shoes where it is desirable to have the shoe fit well, a recess for receiving the fastener is provided at the extension of the heel cap along with the rotary tensioner. Conveniently, it is located in the area above the actual heel portion of the foot. In this regard, if in the upper area of the actual heel portion of the foot (as seen in a cross-sectional view of the foot) the anterior and inwardly curved area of the back of the foot (outer part of the Achilles tendon) Imagine the existence of. This forward inwardly curved part of the foot is then particularly suitable for mounting a rotary tensioner, because it prevents the foot from slipping out of the shoe, It can be mounted particularly suitably. Of course, a rotary tensioner is attached to this area of the foot or in order to avoid undesired pressure on the Achilles tendon. It is convenient for the rotary tensioner to have a relatively flat construction.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first example of the shoe according to the present invention will be described with reference to FIGS. The shoe shown in FIG. 1 is in the form of a sports shoe such as a race shoe or a tennis shoe, and the structure of one of the shoes is shown.

According to FIG. 1, this sports shoe comprises a relatively flexible upper part 1 and a sole 2 of conventional construction.

The instep part 1 has two parts 1a, 1b pulling on each other on the instep part 3 and a rigid heel cap 4 attached or provided on the rear side, which heel cap 4 of FIG. It is shown in a perspective view and will be described in detail later.

The rotary tensioner 5 functions as a central fastener and is carried by the instep 1. The rotary tensioner 5 has a relatively flat structure and corresponds to, for example, EP-A-41290 (in particular, the example shown in FIGS. 4 to 7). Therefore, although it is somewhat clear from FIG. 5, this rotary tensioner 5 has as its basic part a fastener housing 6
It has a cord pulley 7 rotatably and drivably mounted in such a fastener housing 6, a rotary actuating knob 8 rotatable in one direction or the other, and a single pull cord 9.
Both ends 9a of the pull cord are preferably fixed and particularly preferably welded in the cord pulley 7. Thereby, a pull string loop 9b is formed on the outside of the fastener housing 6.

As shown in FIG. 1, several cord flexure guides 10 are distributed along the longitudinal direction of the shoe and are attached to the ends of the instep parts 1a, 1b facing each other. The pull cords 9, in particular the loops 9b of the pull cords, are guided by these cord flexure guides 10, whereby the portions of the pull cords cross each other along the part of the instep, ie at the tightening portion 11. And crossing 12, 12
a is formed. The good construction and the corresponding length of the fastening part 11 ensure that the shoe is fastened at the front side and the upper part of the shoe.

Known per se from rotary tensioners (for example EP-A-41290), it is repeated by a corresponding rotary movement of the rotary actuating knob 8, and thus by a corresponding rotary drive of the lace pulley 7. In order to pull or loosen the flap-like parts 1a, 1b of the upper part together, the pull cord 9 is wrapped around or unwound from the cord pulley 7.

As is apparent from FIG. 1, the shoe according to the invention carries a rotary tensioner 5 on the heel of the shoe. For this purpose, which is shown in detail in FIG. 2, the heel cap 4 has a generally flap-like or strip-like upwardly extending extension 13 at the center 4a of the heel thereof.
The extension 13 has a sufficiently wide width and extends upwards sufficiently high so that it can be configured as a fastener support for receiving and fixing the rotary tensioner 5. There is.

To this end, a recess 14 for receiving a fastener is provided in such an extension 13, for example
Is aligned in a central position with respect to the longitudinal axis A of the shoe or with respect to the vertical center plane of the longitudinal direction of the shoe,
As shown in FIG. 2, the recess 14 is formed in the form of a through hole at the upper end of the extension 13, and its inner diameter is adapted to the outer diameter of the fastener housing 6. Thereby, the fastener housing 6 is received and secured in such fastener receiving recess 14 in such a manner as to form a lock. To that end, as shown in FIGS. 2 and 5, the fastener housing 6 has two hook-shaped projections 15, which are arranged substantially diametrically opposite one another, On the other hand, in the region of the fastener receiving recess 14 of the extension portion 13, a notch 16 having a corresponding shape is formed. Furthermore, a channel-shaped or groove-shaped guide 17 for the part of the pulling string 9 running there.
Are formed in lateral portions of the extension 13 and such guides 17 are arranged substantially diametrically opposite one another with respect to the fastener receiving recess 14.

The heel cap 4 is preferably manufactured in a manner known per se, so as to include wholly or the extension 13. Moreover, the heel cap 4 is formed of a relatively hard material so that a desired hardness can be ensured in this portion of the upper 1. However, the material must be slightly or partially flexible so that the fastener housing 6 snaps into the fastener receiving recess 14 by a corresponding gentle bend of the heel cap 4. However, if necessary for the replacement or repair of the rotary tensioner 5 or the drawstring 9, it can be removed again by bending such a heel cap 4 as well.

By arranging and mounting the rotary tensioner 5 according to the invention on the heel part of the shoe or on the upper part 1 of the shoe, the following is possible. The drawstring loop 9b formed by the drawstring 9 is, in a preferred embodiment, guided generally over the upper 1 of the shoe, whereby the drawstring loop 9b (see dashed line 18 in FIG.
(Represented by), around the foot, from the rotary tensioner 5 carried by the heel cap 4 to the instep portion 3
Extending over or straddling over the tightening portion 11. As a result, as can be seen by FIG. 1, the foot 18 as a whole is particularly well fitted to the shoe. If desired, such mounting can be further enhanced as follows, as indicated by the dashed line 5 in FIG.
That is, the clamp receiving recess 14 with the rotary pull clamp 5 is actually located above the heel of the foot 18 and the loop 9b of the drawstring is the opening 1 for inserting the foot into the shoe.
It is guided along a region just below the upper end 1c of the instep part 1 around 9. As a result, the upper part 1 is the upper end part 1 of the upper part 1.
Even in the area of c, it is located relatively close to the corresponding part of the foot, which makes the wearing of the foot 18 on the shoe particularly strengthened and further improved.

Another example of the shoe according to the present invention will be described with reference to FIGS. 3 and 4. The shoe has a higher instep, i.e. the shoe has a structure in the form of a slightly higher shoe, for example basketball shoes, trekking or hiking shoes and the like. The general or basic construction of the boot according to FIGS. 3 and 4 is substantially the same for one of the shoes shown in FIGS. Accordingly, substantially identical parts of the boot of the second example of the invention according to FIGS. 3 and 4 are provided with the same reference numerals as the example of one shoe of FIGS. 1 and 2, and It is omitted to repeat the detailed description of the light boot portion.

The shoe or boot according to FIGS. 3 and 4 therefore has, apart from the sole, a sufficiently flexible upper part 21 and a rigid heel cap 24 provided on the rear side.
Likewise has two flap-like parts 21a, 21b which can be clamped together on the instep part 23. In this example also, the rotary tensioner 5 is carried by the instep portion 21 at the heel portion, and in fact, it is projected upward in the same manner as in the first example of the present invention shown in FIGS. 1 and 2. The extension 1 is carried by an extension 13 and
3 is configured as a fastener support, in this case reference 2
4 is a heel cap 24.

The structure and function of the rotary tensioner 5 and the guidance of the associated drawstring 9 are accomplished by a suitably configured method substantially similar to that described with reference to FIGS. . In particular, again in this example, the fastener housing 6 is received and secured in the fastener receiving recess 14 of the extension 13 in such a manner as to form a lock, which is described above with reference to FIGS. 2 and 5. As
The same applies to the guide portion 17 and the pull cord 9.

One particular feature of the shoe construction illustrated in FIGS. 3 and 4 will be understood by the following facts.
Heel cap 24 has in its basic design a structure similar to and manufactured in the same manner as the example of FIGS. 1 and 2, but with the sides extending upwards, ie (at least FIG. Stabilizing supports 24a, 24b are formed on both sides at the ankle portion (indicated by the dashed line 20). These stabilizing supports 24a, 24b provide the boot with sufficient and particularly reliable rigidity against bending strains of the ankle joint, without thereby compromising the overall comfort of the shoe.

In this structure, the pull string loop 9
a is preferably guided along the outer surface of the stabilizing supports 24a, 24b, as shown in FIGS. If the corresponding portion of the drawstring is guided along the outer surface of the stabilizing supports 24a, 24b, it is ensured that the stabilizing support will preferably contact the corresponding portion of the foot. One foot against the shoe
The lateral mounting of 8 is preferably done. However, in such a construction, it is a requirement that the heel cap 24 (and its stabilizing supports 24a, 24b and extension 13) be covered by the outer material of the shoe.

However, in many shoe constructions, it may be one shoe as shown in FIG. 1, or
Even in a boot-type shoe having an upwardly projecting upper as shown in FIGS. 3 and 4, the stiff heel cap is located outside the material on the outside of the upper. In such a case, furthermore, the pull cord 9 or its corresponding part (loop 9a) is guided along the inside of the side of the heel cap, approximately between this side and the outer material of the upper, preferable.

In shoes having a high instep as shown in FIGS. 3 and 4, the rotary tensioner 5 described with reference to FIGS. 1 and 2 is located above the actual heel 18a of the foot 18. Preferably, as shown in FIG. 3, the rotary tensioner 5 is now provided in the posterior part of the foot which is the most curved anteriorly and inwardly, without problems and without obstructing the foot. Can be placed.

As is apparent with reference to FIGS. 4 and 5, in the case of a shoe having a structure in which at least the heel cap 4 or 24 is covered by the outer material (outer skin) 25 of the upper 1 or 21, Advantageously, the tensioner 5 or fastener housing 6 is provided within the fastener receiving recess 14 of the heel cap 4 or 24. That is, it is preferable that the rotary operation knob 8 of the fastener 5 has a relatively shallow curved portion and protrudes outwardly beyond the outer material 25 to some extent. This means that the rotary tensioner is provided in the heel cap or its extension 13 so that the rotary actuation knob 8 is sufficiently accessible to rotationally actuate it.

A further preferred example of this shoe will be described with reference to FIG. According to this example, a tension flap 26 is arranged below the uppermost part of the intersection 12 of the tension cords of the tightening portion 11, such a flap 26 extending substantially linearly and in the shape of a substantially strip. And has at least one grip end 26a for pulling the uppermost part of the intersection 12 of the pull cord from the instep part 3,
Is symmetrical about the central axis A of the shoe in the longitudinal direction. This is particularly convenient when the rotary tensioner is constructed in substantially the same manner as the example of EP-A-41290 mentioned above (for example, the examples of FIGS. 4 to 7 thereof). That is, the cord pulley 7 can be released by the thrust motion (reference numeral 27 in FIG. 5) imparted to the lock element in order to release the rotational drive and quickly release the pull cord.

Further, in the construction of this example, the portion of the pull flap 26 located below the uppermost portion of the pull cord intersection 12 forms a sliding guide support for the corresponding portion of the pull cord. You can

Further, the grip end portion 26a of the pulling flap 26 is attached to the outer surface of the instep portion 1 at the tightening portion 11,
It is attached so that it can be loosened. In particular, if the pull flap 26 is relatively long, it may be attached, for example, by hook and loop fasteners, push buttons, or the like. In such a case, as shown in FIG.
If the majority of the tension flaps 26 extend generally centrally in the longitudinal direction beyond the fastening section 11, such tension flaps 26 can cover at least part of the intersections of the tension cords.

[0032]

According to the present invention, a rotary tensioner can be easily and securely attached and, in addition, the shoe can be very well globally tightened and thus securely and firmly held. it can.
