Description

4 shoe with a central closure

~ \

The present invention relates to a shoe with a central closure according to the preamble of An¬ award. 1

Such a shoe is known from DE-90 16 325 and Ü has proven very useful in sporting and leisure shoes with a low shaft and with a single circumferential clamping element. From the DE-U-90 16 325 it is also known to use a single central shutter for two clamping elements.

When using a central closure for a shoe with a high upper, the problem arises that, depending on the foot or leg design of the user and depending on the used stockings and / or any trousers, which may still reach into the shoe upper, in Vorder¬ foot or in the instep region other locking paths are given as the area of ​​the high shaft or in other shoe areas. Moreover, the high shaft must normally be opened wider than the shoe or in Vorderfu߬, in the instep area, to ensure easy entry and exit. Therefore, with the present invention, the object is to be solved to make a central lock of the aforementioned type in such a way that even with different sizes closing Because of the entering for use clamping elements a perfect closure of the shoe upper portions of both over the instep and in the shank portion adjoining the Rist or is possible in other areas shank.

This object is achieved by the features specified in the characterizing part of claim 1.

By the use of the two from one another both unab¬ pending and jointly actuatable tensioning means of the central closure and the possibility of simultaneous opening or expansion of the same is ensured individual adjustment and optimization of the effect of the central shoe closure. The central locking can be applied and is thus independent of the high shank design a shoe, although it is particularly suitable for this at different points of a shoe, even on a shoe, with equally good or an¬ approaching equal success.

Further advantageous details of the invention are specified in the dependent claims and will be described in more detail below with reference to the embodiment illustrated in the drawings embodiments.

In Figure 1, a central closure is designated by 1, which is arranged on a shoe 2, in particular a sport, leisure or rehabilitation shoe, in the joint region. 3 In the illustrated shoe is a shoe Hochschaft-, as commonly used for example for basketball, handball, baseball or the like. The shaft 4 can also be formed even higher than shown in the drawing.

Below the central closure 1 is a preferably made of hard-elastic material Ristab¬ begins cover 5, which may extend into the region 6 of the metatarsophalangeal joints. Optionally, the instep cover 5 is formed of soft in the range 6 by softer material is used there and / or there are transverse grooves 7 there are provided, in order to allow elastic bending in the area. 6

The central closure 1 is assigned two clamping elements 8 and 9, which is also operable in accordance with the present invention either individually or in common via coupling means in closing and opening direction. To this end, in. Central closure comprising two independently operable clamping devices 10 and 11 are provided 1, as can be seen from the illustrated partly in section central closure 1 of FIG. 2 These clamping devices are formed as pulleys 10 and 11 in the illustrated embodiment. Each pulley 10 and 11, a clamping element 8 and 9 respectively fixedly connected. The upper pulley 10 is connected to the clamping member 9 which extends downwardly and forwardly in the forefoot over the instep and attack via suitable deflecting means on the lateral shaft portions 12,. 13 Therefore, this clamping device 10 of the shoe 2 can be closed over the instep and tensioned.

At the coaxial with the pulley 10 and below the same mounted pulley 11, the clamping element 8 is mounted extending in the joint region 3 or above to the closing parts 14, 15 of the high stem 16 rearwardly. In this way, the high shaft 16 in the ankle area or above can be closed.

Figure 3 schematically shows the aforementioned closing areas. In the region 17 of the instep the closing or opening via the clamping element 9 and in the region 18 of the high stem 16 8 via the clamping element takes place suitable deflection elements 19 are to tension respectively provided on the shoe or stem parts, as is indicated by dashed lines in FIG. 3 In the illustrated arrangement, the clamping member 9 crosses over the instep once, for example in guides of the instep cover. 5

However, it is also a cross-free tensioning of the tensioning element 9 possible by suitable 5, indicated by dashed lines deflection elements are provided on the instep covering 20.

To prevent contraction of the front part of the boot and high shaft 16 in the joint region 3, and thus the mobility thereof not to limit, the portions 21 of the tension member 9 are guided in this region in not or hardly contractible or collapsible guides 22nd These guides 22 are indicated by dashed lines in the figure 3 and forms ausge¬ in Figure 1 as a relatively rigid tube. For example, the guides 22 may be made of a coiled pipe to a wire, such as in Bowden cables usual. but it can also be used suitable metal or plastic pipes or the like, or they can in the. 5 instep covering, or incorporated into another element or be provided therein.

In order to obtain a shoe with only slightly protruding over the surface elements, the central closure is advantageously formed with flat disks as clamping devices. Such embodiments are shown in Figures 4 to 13 in detail and will be described in accordance with the following.

4 shows this central closure 1 from the side according to the section II of Figure 7, wherein in the left half of the drawing the sheaves are shown in section and in the right half of the drawing, only the housing 23 of the central closure 1 shown in section is.

The substantially dosenformige housing wall 23 with the bottom part 24 has a central or rotational axis 25 on the housing 23 resilient tabs 26 are attached downward radially inward and obliquely upward. In the housing, an axially displaceable pressure disk 27, an axially displaceable and rotatably mounted sheave 11 and a rotatable and optionally axially displaceably mounted sheave 10 are each housed. The pressure plate 27 may possibly be omitted for space reasons. On the pulley 10, a disk-shaped rotary handle 28 (dashed lines) and are rigidly coupled thereto. The rotary handle 28 engages behind a circumferential snap edge 29 and holds the assembly against the spring force of the resilient tabs 26 in the position shown.

The sheaves 10, 11 are coupled via side cross with each other in the clamping direction coupling agent unlatched. The coupling means here consist of a respective toothed ring 30 and 31 respectively with the same type and at the same toothing. The coupling means are designed such that upon actuation of the rotary handle 28 and thus the pulley 10 in the closing direction - is rotated, the lower sheave 11 - in the embodiment in plan view in a clockwise direction. Here, each steep tooth flanks 32 and 33 together to engage. The respective other tooth flanks 34 and 35 extend to the tooth bottom 36 each relatively flat.

The lower pulley 11 has a second ring gear 37 with preferably radially projecting teeth. This is formed similar to the teeth of the first ring gear 31 and can latch with snap prongs 38 which are resiliently deflectable is provided on the housing wall 23rd may be the housing 23 is preferably made of a resilient material so that the locking zinc spring 39 formed of this material, in particular cut free, as shown in FIG. 6 The ring gear 37 and the locking prongs 38 are wide and arranged to each other and the axial stroke 40 of the lower pulley 11 against the spring force of the flaps of such a size 26 such that with sufficient axial displacement of the sheave 11 downwardly of the ring gear 37 out of engagement with the locking prongs 38 is coming. Thereby, the unlatching of the sheave 11 is possible. For winding and unwinding of the clamping elements the pulleys 8 and 9 are 10,11 provided on the periphery 41 thereof, each having a Seilführungsnut 42 and 43rd The attachment of the clamping elements 8 takes place 9 by turning on or conducting in direction of the arrow P of the same in a to the center 44 (Figure 9 a) or to the central axis 25 (Fig. 4) laterally offset Inappropriate bore 5X (Fig. 9, 10) which opens out in each case in the Seilführungsnut 42 and 43rd The clamping can take place by deformation of the bore wall 46th

The mode of operation of the central closure 1 during closing of the shoe 2 from the open state is the following:

The sheaves 10, 11 are in the position shown in Fig. 4 position. Is now the upper pulley 10 is rotated by rotating the handle 28 clockwise, the lower pulley 11 via the sprockets 30, coupled force or form-fitting 31 and is rotated. In this case, the locking prongs 38 skip the teeth of the second ring gear 37 of the lower sheave 11 and lock it in the final rotational position. both clamping elements are tensioned 8 and 9 consequently. The shoe 2 is then closed over the instep and the upper shaft portion and brought into a part closed position.

When the desired closed position is in the forefoot, so over the instep, achieved is not yet closed usually the high shank 16 since the closing path is significantly greater. To produce the desired closing effect here too, the lower sheave 11 must further rotated in the closing direction and the upper clamping element 8 are tensioned without the upper pulley 10 is further rotated in the closing direction. This is done by decoupling the two pulleys 10, 11. For this purpose, the upper pulley 10 is rotated via the rotary handle 28 counterclockwise, ie in the opening direction. The lower sheave 11 remains in its rotational position as it is latched by the latching prongs 38th

During turning the .- steep flanks 32, 33 of the sprockets 30, 31 to slide out of engagement and the flat tooth flanks 34, 35 come. Successively. Thereby, the lower sheave 11 is pressed axially against the force of the resilient tabs 26 downwardly until the tips of the teeth 47 of the ring gear 30, the tips of the teeth 48 of the ring gear 31 (Fig. 8 and 11) skip and snap into the respective following tooth groove. However, the latching between the latching teeth 38 and the ring gear only the contact length is not yet canceled 37, but reduced. By subsequently turning the handle 28 in the closing direction are again both pulleys 10, moves in the closing direction. 11 Thereby, the lower sheave 11 is further rotated, while the upper pulley 10 is optionally brought into their closed position prior. By repeatedly back and forth the turning handle 28, only the lower sheave 11 thus the clamping element 8 further tensioned and the closing action of the high stem thus is further rotated 16 increases to the desired closed position.

If this closing position is to be maintained, it is necessary after, the release of the rotary handle 28 and the upper sheave 10 maintain their rotary position. This is accomplished in the embodiment by a sufficiently large frictional force can be obtained over the rotating handle 28 with the housing wall 23rd However, it is also possible, similar to lock the upper pulley 10 of the lower pulley 11 and also to permit unlatching by an axial displacement, for example by pressing on the knob 28 or by means of a valve provided in or under this actuator. A clamping device suitable type can be provided. Likewise, the lower sheave 11 could be provided instead of a locking via the second ring gear 37 and the locking prongs 38 with a similarly acting clamping device.

To both clamping devices 10, 11 to bring the same into the open position, an actuating or Entrastglied 25a may be provided with which the latching and / or clamping effect of the two clamping devices 10, 11 can be lifted simultaneously. one, two clamping devices 10, 11 common actuating or Entrastglied 25a for this purpose is preferably provided.

Finally, the upper pulley 10 may be driven via a reduction or step gear. This would, where appropriate, in place of the rotary handle 28 to attach and provided with a rotary handle in turn. The drive can take place in this case three offset by 120 ° are arranged axes 49, 50, 51 (Fig. 13), for example via a planetary gear, as known from EP-OS 0255869, Figure 12, or through other on known central locking is known to take place.

It will be recalled that provided with the new central locking shoe does not necessarily have to have an ankle-high or even higher stem. There are also possible cases where also shoes or the like. With the central lock and the double slide described can be provided in order to ensure better locking effects in different closed ranges. By the use of two mutually independent, but also jointly adjustable clamping devices 10, 11 is allowed to span a particular shoe portion or slack, while the other shoe is already the range of the necessary closing voltage.
