Definitions
- the present invention relates to a shoe provided with a locking device, in particular sports, leisure or rehabilitation shoe, with a shaft material which is flexible with respect to tensile stresses in the closing area or with a plurality of flexible shaft materials according to the preamble of claim 1.
- a sports shoe, namely football boots, with a locking device of this type is known from DD-PS 89 796.
- each side of the instep shield can be tied in the instep area with a tab provided on the side parts of the shoe upper by a lacing by threading a shoelace through tying holes in the instep plate and in the side flaps and tying behind the heel part of the football boot.
- a lacing arrangement punctual pressures when tightening a lacing that usually runs over the instep are reduced and thus the blood circulation in the instep area is no longer impaired as much.
- the closing flaps are also attached directly to the sole, namely between the sole and the upper. This prevents tension between the riser plate and the upper material.
- the riser plate should only be able to be pulled down and back towards the instep of the wearer.
- the present invention is intended to achieve the object of improving the previously known double lacing with an instep plate in the instep area in such a way that it is possible to simply insert the instep plate and the side parts of the shoe shaft over the entire closing area and with closing or Tension the clamping force against each other in order to ensure the most uniform possible pressure distribution along the entire closing area, if possible also over the area of the arch of the instep of the foot, that is to say transversely to the longitudinal direction of the shoe.
- the present invention ensures that the mutual position of the tensioning element guides in the riser plate or is precisely defined and optimized with respect to one another in the locking tabs and that the clamping element (s) is not or will not be pinched by the closing pressure of the riser plate and the locking tabs, and also not selectively and / or in partial areas of the closing area.
- a largely continuous adjustment of the bracing is possible in a simple manner by means of the central turnbuckle.
- the locking device designed according to the invention can be prefabricated as a unit when using an assembled arrangement of instep shield and locking tab, pre-tested and attached to the corresponding shoes, in particular sports, leisure or rehabilitation shoes, as a securely functioning clamping unit.
- the arrangement of the clamping element (s) can in principle be carried out without crossing.
- one or more crossings of the tensioning element (s) can also be present, depending on the shaft height of the shoe.
- a special configuration of the intersecting grooves ensures that the clamping element (s) crosses with little or no friction in these embodiments of the present invention, since these can be designed such that they do not lie on one another at any point.
- the locking device can be easily tensioned and relaxed and, in addition, wear is avoided completely by avoiding high pressure at the point of intersection of the clamping element (s).
- the use of elastic or resilient material for the closing device creates a relatively stable end edge at the shoe opening at the end of the closing area.
- this can be used by a special configuration of the tongue end part to stabilize or fix the position of the tongue with respect to the closing device and also to enable targeted guidance of the opening or closing upper end parts of the shoe upper.

- the sliding foils 17 enable the closing flaps 3, 4 to be pulled up easily, with little friction, against the riser plate 2, and the same kind of low-friction suspension in the relieved state.
- the sliding films 17 thus support the parallel or wedge-shaped closing movements of the locking tabs 3, 4 towards the riser plate 2 or away from it.
- round or rounded recesses 18 are provided at the connection points in the lower region of the riser plate 2, that is to say at the beginning of the opening gap 16, in order to reduce the notch effect at these connection points.
- a steel wire or a wire rope can be used as the tensioning element or tensioning elements 11, which can possibly also be surrounded by a plastic sleeve with good sliding properties.
- the clamping element 11 can also consist of a Bowden cable 19, as shown in Fig. 4.
- the casing 20 of the Bowden cable 19 has compressible areas 22 between the fixed articulation points 21a, 21b on the riser plate 2 and on the locking tabs 3, 4.

- the deflection elements or blocks 23 are provided or attached to the closing flaps 3, 4 at mutually opposite locations and the riser plate 2 has no guide channels 13 and / or deflection elements or blocks 23 here.
- the tensioning element 11 is thus alternating in the center area MB looped from one to the other locking tab 3 or 4 around the corresponding deflection elements or blocks 23 and can be tensioned and relaxed from the central lock 12. This results in a crossing point 26 of the clamping element 11 in the central area MB of the locking device, whereas in the upper part 27 and in the lower part 28 of the locking area SB the locking tabs 3, 4 are connected to one another without crossing.
- the tensioning element 11 is guided in grooves 29 to 33 over the riser plate 2. This ensures good guidance of the tensioning element or the tensioning elements 11 in these areas and also the pressure of the tensioned tensioning element 11 on the riser plate 2 is reduced and thus the friction is reduced.

- a flap cover 36 or 37 can be provided on the locking tabs 3, 4 in order to cover the, for example, curved guides for the tensioning element 11 or the guide grooves 25 shown in FIG. 5A.
- the flap covers 36, 37 have openings 38 in corresponding locations, into which the deflection elements or blocks 23 engage or, for example, snap in with the projecting upper edge 24.
- a sliding film 17 can be provided between the riser plate cover 34 and the adjacent tab covers 36, 37, as was described with reference to FIGS. 1 and 2.
- the instep shield cover 34 and the flap covers 36, 37 consist of a single component, for example a stamped, injection-molded or cast part.
- a membrane 39 connected to the adjacent components can also be provided, in particular molded on, for example splashed. This membrane 39 is preferably collapsible or collapsible, primarily in the form of a bellows (FIG. 6 A).
- At least one tensioning strap 41 or 42 can be attached to each closing flap 3, 4 in the region 40 of the midfoot (FIGS. 8 and 9), which straps laterally around the foot into the sole region 43 (FIG. 10) of the shoe and is preferably or exclusively firmly connected to the sole material of the shoe, for example glued, sewn or riveted.
- tensioning straps 41, 42 are indicated by dashed lines in FIG. 5, it being possible for one tensioning strap 41 to be present on one, preferably on the inner locking tab, and two tensioning straps 42 on the outer locking tab.
- two tensioning straps 41 and 42 are provided on the two locking tabs 3, 4, each of which runs parallel or approximately parallel to one another.
- the tensioning straps 41, 42 can advantageously be connected to one another by a bracket 44 which extends through the entire sole 45 (FIGS. 7 and 10).
- the riser plate 2, the locking tabs 3, 4 and the tensioning straps 41, 42 including the bracket 44 advantageously consist of a uniform injection, casting or molded part.
- the straps 41, 42 can, for example, on the inside 46 of the shaft material 47, or within the same between the outer material and the lining of the shaft, or on the outside of the shaft (Fig. 10). In the arrangement on the outside of the shaft material, these tensioning straps 41, 42 can also be arranged under or over trimmings of the shaft material.
- the tensioning straps 41, 42 advantageously end below the insole 48 or the bracket 44 runs below this shoe part.
- the central lock 12 thus fulfills a multiple function in these embodiments of the present invention. It not only serves to produce a uniformly adjustable closing pressure which is evenly distributed via the riser plate 2, but at the same time it requires increased stability of the entire shoe in the sense that the risk of overexpansion of the sensitive joints and tendons, preferably in the outer area of the shoe, is largely reduced becomes.
- the tongue 10 is held in the correct position relative to the closing area and especially prevented from slipping into the shoe.
- This advantage is particularly given if the stop wall 54 of the thickened tongue part 53 forms at least approximately a right angle with the non-thickened part of the tongue 10.
- the protruding tongue part 53 tapers towards its upper free end and ends there with a rounding 55, as can be seen from FIG.
- the lateral edge regions 56, 57 of the tongue 10 taper - as is known - towards the tongue edges, as shown in FIG. 13.
- the shoes designed according to the invention with the described central locking device are suitable not only for normal street shoes, sports and leisure shoes, but also for rehabilitation shoes, i.e. for shoes in which the described advantages in operation and in the strength of the central locking system are particularly important.
- connection of the locking tabs 3, 4 to the end 5 of the riser plate 2 is designed to be as easily movable as possible. This can be done, for example, by the hinges or joints mentioned above, in particular spring joints.
- connection of these parts of the central locking device in the connection area 58 takes place via corrugated or folded membranes 39.1, each of which is also the continuation of one provided between the riser plate 2 and the locking tabs 3, 4 in FIG. 14 can be membrane 39.2 shown in the left part of the closing device and extend up to or almost up to the end edge 5.1 of the end of the riser plate 2.

- a connection of the locking tabs 3, 4 to the riser plate 2 may be omitted entirely.
- the folded membrane 39.1 or 39.11 preferably runs in the direction of a real or imaginary connection point 59 between the riser plate 2 and the locking tabs 3, 4, as shown in FIG. 14, or from the connection point 59.1 between the riser plate cover 34 and the tab covers 36, 37 - corresponding to the representation according to FIG. 15 - from to the end edge 5.1 of the end 5 of the instep shield 2 according to FIG. 14 or to the end edge 5.11 of the end 34.1 of the instep shield cover 34 according to FIG. 15.
- connection areas 58 and 58.1 of the riser plate 2 and, if necessary, the riser plate cover 34 their ends 5.1 and 34.1 are preferably provided by suitable measures, for example by means of low material thicknesses and / or by additional transverse grooves or transverse shafts 15.1 (see FIGS. 14 and 15), in particular in the form of a corrugated or folded membrane, highly resilient.
- transverse grooves 15.1 can overlap the folds of the membranes 39.1 and 39.11.
- openings 38 are provided in the tab covers 36, 37 at corresponding points, into which the deflection elements or blocks 23 engage or, for example, snap in with a projecting upper edge.
- Reference numbers 39 preferably denote collapsible or collapsible membranes.
- tensioning straps 41, 42 When tensioning straps 41, 42 are used, they can, as shown in FIG. 7, be molded directly onto the locking tabs 3, 4 during their manufacture. But they can also be attached to them in an otherwise suitable manner, for example by sewing, riveting, gluing or the like.
- the deflection elements or blocks 23 are expediently arranged on the locking tabs 3, 4 in such a way that they are aligned with the tensioning straps 41, 42, as shown in FIG. 16. As a result, the tension of the tensioning element 11 is transmitted directly to the tensioning straps 41, 42.
- the tensioning straps 41, 42 can be separated from the locking tabs 3, 4, as shown in FIG. 17, the deflection elements or blocks 23 then being provided at the ends 41.1 and 42.1 of a tensioning strap 41, 42 each.
- deflection elements or blocks 23 deflection elements or blocks of a suitable other shape and construction, in particular in the form of loops, holes, eyelets, ghilly eyelets or the like, can also be provided.
- the deflection elements or blocks 23 can be formed on the tensioning straps 41, 42, clipped on, glued, riveted or fastened in some other way.

- the ends 41.1 and 42.1 of the tensioning straps 41, 42 are inserted through slots 60 from below, overlapping the locking tabs 3, 4.
- Each deflecting element 23 or each deflecting block advantageously has a stop edge 61 at the upper end.
- This stop edge 61 is expediently first removed from the upper slot edge 62 by a certain amount, for example 5 mm to 20 mm, when the closing device is open.
- a certain amount for example 5 mm to 20 mm
- the tensioning straps 41, 42 first occur during the closing operation through the tensioning element 11, as a result of which the foot is held in the shoe. Only when the tensioning element 11 is tightened further does the abutment edge 61 abut the upper slot edge 62 and thereby bring the locking tabs 3, 4 into the closed position. This ensures a good fit of the foot in the shoe. Accordingly, when the central turnbuckle 12 is unlocked, the locking device first opens, and then the foot is loosened in the shoe by further relaxation of the tensioning straps 41, 42.
- the deflection elements or blocks 23 on the tensioning straps 41, 42 can be connected to one another by a web 23a, as is shown schematically in dashed lines in FIG. 20.
- the common stop edge 61 thus abuts the respective locking tabs 3 and 4 over a wide area.
- the area of the width adjustment is to be as uniform as possible with straps 41, 42
- the tensioning straps 41, 42 can be provided at their end regions adjacent to the locking tabs 3, 4 with latching elements 41.2 or 42.2 of a known type, such as pin-hole connections, screw connections or the like, which fasten the deflection elements or allow blocks 23 or the differently configured deflection elements at different locations on the end regions of the tensioning straps 41, 42.
- latching elements 41.2 and 42.2 are shown schematically in FIG. 19.
- one or more lateral connecting webs 63 are advantageously provided between the adjacent tensioning straps 41, 42.
- the tensioning straps 41, 42 can also be connected to each other on one or on each side of the locking device with a bracket 44 and adjacent brackets 44 can also be connected to one another by a further fastening web 64, as can also be seen in FIG. 20. This ensures easy installation of the complete cage consisting of the tensioning straps 41, 42, the connecting webs 63, 64, the brackets 44 and the riser plate 2 or - in the case of a separate riser plate 2 - the partial cage then present.
- the connecting webs 63 and the further webs 44 and 64 ensure easy positioning of the tensioning straps 41, 42 on the finished shoe upper, because the aforementioned complete cage or partial cage is easily pushed onto the shoe upper and very much there due to the material elasticity can be easily fixed
- a further advantageous embodiment of the invention consists in that, according to FIG. 21, with tensioning straps 41, 42 not connected to the locking flaps 3, 4 (only tensioning straps 42 are shown in the drawing) on the tensioning straps 41, 42 deflection elements or blocks 23 and the side areas of the Instep plate 2 further deflection elements or blocks 23 are provided.
- further deflection elements or blocks 23 are provided on the locking tabs 3, 4, which are provided between the deflection elements or blocks 23 on the tensioning straps 41, 42 and on the riser plate 2.
- the deflecting elements or blocks 23 or otherwise configured deflecting elements can, however, also in slots 65 in each case on the edge of the riser plate 2, the locking tabs 3, 4 and / or the tensioning straps (FIG. 24) or only in slots 65 on the locking tab 3, 4 and if necessary be arranged on the tensioning straps (Fig. 25).
- the deflection elements or blocks 23 can in this case be designed as a semicircular disk 66 or also as a pin, bolt or the like (cf. FIGS. 24 and 25).
- the deflection elements or blocks 23 or the otherwise configured deflection elements are provided on the outside of the riser plate 2 and only on the adjacent locking tabs 3, 4 in slots 65.
- a material which is clear as glass or cloudy and which can also be transparent in color can be used as the material for the tensioning straps 41, 42. be used. This makes it possible to quickly identify and remove any contamination under the tensioning straps 41, 42.
- the shaft material 47 underneath is also visible, as a result of which the aesthetic effect of the shoe is retained and, if appropriate, trademark markings on such a shoe remain visible.
- the guide channels 13 are formed according to the invention in that the locking tabs 3, 4 each have at least one inwardly extending slot 101 groove 101 on the narrow sides 3.1, 4.1 facing the riser plate 2. At least one deflecting element or block 23 for receiving the tensile forces occurring during tensioning of the tensioning element 11 are inserted into the grooves 101 on both sides of the riser plate 2 and fixedly arranged in the grooves 101, the tensioning element 11 each having an arcuate sliding surface of the deflection elements or blocks 23 wraps around.
- the width 101.1 of the grooves 101 is the same or only slightly larger than the thickness of the deflection elements or blocks 23.
- at least one deflection element or block 23 is inserted and fastened, for example glued and / or welded in.
- a guide groove 25 (FIG. 27A) serving as a sliding surface is provided, in which the tensioning element 11 comes to rest.
- the deflection elements or blocks 23 consist of a material which is harder and more abrasion-resistant than the material of the riser plate 2 and that of the locking flaps 3, 4, such as polyamide, polyethylene, polyurethane or the like, with a hardness of preferably greater than 75 Shore A.
- the material of the instep plate 2 and that of the closing flap 3, 4 can therefore preferably be selected from the point of view of elasticity or spring elasticity and less from that of abrasion resistance.
- the guide channels 13 run in the plane of the riser plate 2 or the closing flaps 3, 4 and are arranged offset with respect to one another in such a way that the tensioning element 11 extends at least approximately in an S-shape or in a serpentine manner. This ensures that the tensioning element 11 is not clamped in partial areas, such as the central area MB, during tensioning over the entire closing area SB.
- the arrangement of the guide channels 13 is selected such that in the case of closing flaps 3, 4 used on the riser plate 2, an opening 14 of a guide channel 13 is congruent with the opening 14 of the opposite guide channel 13.
