Description

The invention relates to a shoe, for example a high-heeled shoe, such as hiking boots, hiking boots or the like, according to the preamble of claim 1.

In such shoes, the problem often occurs that the tongue slips laterally after some gestation, due to the anatomy of the foot regularly to the foot outside. Especially with footwear for recreational sports, such as hiking boots, mountain boots and the like, in which the foot is frequently and strongly moved, and rubbing accordingly strong on the shoe, painful bruises or abrasions can be the result, if the tongue is not in their "correct or desired central position with respect to the slot is. One cause of the mentioned slippage is the so-called "blasting", i. a preforming of the tongue according to the contour of foot and possibly lower leg. If the forefoot is now bent towards the tibia while walking, the tongue is deflected correspondingly strongly in the instep area. The tongue now tries to dodge the forwardly pressing lower leg and maintain its preformed position. The result is that she dodges sideways. The fact that they mostly evades the outside of the foot depends on the anatomical differences between the outside of the foot and the inside of the foot.

In order to prevent this lateral slippage of the tongue and to keep the tongue in the desired relative position with respect to the foot, it is well known in the art, a hook or on the tongue to provide loop-shaped retaining element. This holding element is when inserting the shoe into the closure device, for example, the two ends of a shoe lace, hung or inserted to prevent by pulling upwards lateral slipping of the tongue. This effect can only be achieved effectively by the known holding element when the tongue is in an ideal position in which it runs in accordance with the instep of a "standard foot" of an ideal carrier defined for the respective shoe construction.

If the wearer has a low instep, the position of the holding element changes together with the tongue starting from this ideal position downwards, whereby the holding element is loaded by the laces running at this point in such a way that ultimately the risk of tearing off of the holding element of the tongue exists. On the other hand, if the wearer of the shoe has a high back of the foot, then the retaining element position moves upwards with the tongue. As a result, the crossed ends of the shoelace can hardly grasp the holding member, so that it loses its effect.

In addition, in the known holding elements emanating from the crossed ends of the shoe lace holding or centering force due to the flat pressure angle between the holding element and shoelace relatively low.

From the generic US-A-6,158,096 For example, a shoe is known with a tongue holding unit formed separately from its tongue, in which the hook plate of the tongue holding unit extends substantially in the longitudinal direction of the tongue.

The WO 2006/129939 discloses a shoe on the tongue of which a plurality of eyelet elements are secured, which cooperate with other eyelet elements attached to the edges of the tongue gap via a lace.

And from the US-A-1,386,985 For example, a shoe with a tongue holding unit inserted into an opening of the tongue is known.

It is therefore an object of the invention to provide a shoe of the generic type, in which the tongue holding device also effectively filled their function when the foot of the wearer does not correspond to the "standard foot" for this shoe.

This object is achieved by a shoe according to claim 1.

While in the shoes of the prior art, the tongue-holding unit can be properly engaged with the crossed ends of the lace only when the wearer has the "standard foot" for which this shoe is designed, or a lower instep foot than the " Normfuß ", ie can not be brought into engagement with the intersecting ends of the lace when the foot of the wearer has too high instep, the tongue holding unit according to the invention can be brought into engagement with the two holding elements, regardless of the shape of the foot. Namely, there is a problem with the shoes of the prior art that the engagement of the tongue-holding unit with the lace due to the oblique course of the lace from one edge of the slot to the other edge to a kind of "slope force", the amount of which has a relatively low value due to the relatively shallow slope of the lace. In addition, the value of this force depends on which force directed in the direction of the longitudinal extent of the slot, the shoelace ends act from below on the retaining element. In contrast, the holding elements according to the invention can be brought into positive holding engagement with the tongue holding unit. This ensures that the pulling force originating from the holding elements and directed essentially in the transverse direction of the shoe can be introduced in full into the tongue holding unit. Due to the interaction of the two opposite edges of the slot associated holding elements, the tongue can thus be kept regardless of the shape of the foot of the shoe wearer in the desired desired position.

The at least one retaining element may comprise, for example, a retaining loop which extends from the associated edge of the slot and after deflection by the tongue retaining unit to the associated edge is returned. In a particularly simple embodiment, this retaining loop may be formed by a portion of a shoe lace serving to close the shoe. Note that, in this connection, since the lace is guided from a first hook and loop member disposed at a contemplated edge of the slot to the tongue holding unit and after deflection, the course pattern of the lace in the tongue holding unit area deviates from the conventional cross pattern returns to the same slot edge by the tongue holding unit. Nevertheless, the lace can fulfill its closing function, since, when a pulling force is exerted on both free ends of the lace, which has already been deflected by the tongue holding unit, this tensile force is transmitted to the other edge of the slot by the tongue holding unit.

The tongue holding unit may for example comprise an abutment element, which is associated with both holding elements together. In this case, the abutment element may be a deflecting element, which is associated with both holding straps together.

According to the tongue holding unit is formed separately from the tongue and attached thereto . This, too, on the one hand facilitates the manufacture of the shoe according to the invention and on the other hand ensures a sufficient strength of the tongue holding unit, since in this case it can be made of a relatively rigid material, in contrast to the relatively soft material of the tongue. In this case, the tongue holding unit, for example, as a stamped and bent part, preferably made of sheet metal, be made.

In order to increase the stability of the tongue holding unit on the tongue, the tongue holding unit according to the invention comprises a spacer which can be placed on the tongue by means of a contact plate, and a hook plate, which is arranged at the end facing away from the tongue of the spacer and at least in two both opposite circumferential edges of the slot facing radially projecting beyond the spacer element. In this case, the two sections of the hook plate projecting beyond the spacer element form hook elements which, in the closed state of the shoe, secure the holding elements on the tongue holding unit.

Another such hook element can be formed in that the hook plate also projects radially beyond the spacer element in a peripheral region facing the shoe tip, preferably over the entire circumference of the spacer element. For those shoe wearers who can not make friends with the new way to tie the laces, this additional hook element can take over the function of a conventional hook element, as it is also present in the conventional shoes of the prior art.

For example, the hook elements discussed above may all be formed by the hook plate projecting beyond the spacer over substantially its entire circumference, including at least a portion of greater radial extent and at least a portion of minor radial extent beyond the spacer. In this case, the largest radial extent does not necessarily have to be present in the circumferential areas facing the two opposite edges of the slot or the peripheral area facing the toe. Taking into account the course of the holding elements, for example the laces, the invention provides that the radial extent of the hook plate projecting beyond the spacer element is greatest in at least one circumferential section, preferably those four circumferential sections, which or which intersect with the tongue longitudinal axis at an angle of about 30 degrees and about 60 degrees, preferably about 45 degrees. It should not be excluded according to the invention that at least two of the peripheral portion are connected to each other with the largest radial extent, as long as the associated peripheral portion only two subsections which includes an angle of between about 30 ° and about 60 °, preferably about 45 ° with the tongue longitudinal axis and as long as the entire circumference of the hook plate comprises at least a portion of greater radial extent and at least a portion of minor radial extent beyond the spacer.

In order to ensure a secure holding of the holding elements, for example the shoelace, it is advantageous if the radial extension of the hook plate projecting beyond the spacer element in the at least one section of greatest radial extent between about 4 mm and about 7 mm, preferably about 5.5 mm, is.

In addition, it is proposed in a further development of the invention that the hook plate is curved at least partially curved away from the tongue at its peripheral edge and / or that the abutment plate has a curvature adapted to the shape of the tongue. In this way can - an insertion of the retaining elements, such as the laces, facilitating instruction bevel provided.

In order to ensure a good grip of the holding elements, such as the laces, the length of the spacer may be between about 2.5 mm and about 3.5 mm, preferably about 3.0 mm. These dimensions are based on the fact that the laces usually used in the untensioned state have a diameter of about 4 mm and in the tensioned state, a diameter of about 3 mm. It should be noted that the value specifications for the "lace diameters" refer to effective diameters, i. Diameter of a circular disc, which has the same cross-sectional area as the laces.

In addition, the tongue holding unit may be attached to the tongue by means of a single fastener, for example by means of a single rivet.

Regardless of how the tongue holding unit is attached to the tongue, the spacer may be tubular but advantageously the only fastener penetrates the lumen of the tube.

If the tubular spacer element is penetrated by a fastening element, preferably by the single fastening element, this fastening element serves at the same time for fastening the tongue retaining unit to the tongue and for deflecting the two retaining elements, in particular shoelace loops.

In FIG. 1 a shoe according to the invention is generally designated 10. The shoe 10 includes a high shaft 12, ie, a shaft that extends beyond the ankle of the wearer. From an upper edge 12a of the shaft, a slot 14 extends, which extends in the direction of the toe 12b. The slot 14 is covered on the inside of the shaft 12 by a tongue 16, which is usually connected in the region of the lower slot end 14a with the shaft 12, for example sewn thereto. To close the shoe 10 is a shoe lace 18 which is guided in the forefoot and ridge portion 12c of the shaft 12 following a crossed course through eyelet members 20 which are secured along the edges 14b and 14c of the slot 14 on the shaft 12. Furthermore, in the region of the lower leg region 12d of the shank 12, hook elements 22 adjacent to the slot edges 14b and 14c are provided. Finally, a tongue holding unit 24 is mounted on the tongue 16 substantially at the level of the hook elements 22.

As well as in the FIGS. 3 and 4 is shown, the tongue holding unit 24 comprises a contact plate 26, with which it rests on the surface of the tongue 16. On the contact plate 26 integrally closes a tubular formed spacer 28, at its side facing away from the contact plate 26 end turn a hook plate 30 is formed. Further, in the tongue holding unit 24, a through-hole 24 a is formed, which serves for passing through a fastening element 36, by means of which the tongue holding unit 24 can be fastened to the tongue 16. The fastening element 28 may be formed, for example, by a fastening rivet.

In the illustrated embodiment, the hook plate 30 projects beyond the spacer 28 on its entire circumference, forming hook elements in both the portions 30a and 30b facing the two edges 14b, 14c of the slot 14 and the portion 30c facing the shoe tip 12b serve the secure hold of the lace 18 on the tongue holding unit 24.

According to a in FIG. 1 At the level of the tongue holding unit 24, a lace loop 18a1 exits from a first hook element 22 in the region of the slot edge 14c, is deflected by the spacer element 28 of the tongue holding unit 24 and returns to another hook element 22 in FIG Area of the same slot edge 14c back. Similarly, at the level of the tongue holding unit 24, a lace loop 18b1 extends from a first hooking element 22 in the region of the slit edge 14b, is deflected by the spacer element 28 of the tongue holding unit 24 and returns to another hooking element 22 in the region of the same slotted edge 14b. The spacer element 28 thus forms an abutment element for the loops 18a1 and 18b1.

According to the above, the tongue holding unit 24 is held by the two loops 18a1 and 18b1 at the position given to it when the lace 18 is laceed in the transverse direction Q, irrespective of the position of the tongue holding unit 24 in the height direction predetermined by the instep height of the wearer's foot 12 H. doing so For example, the adjustment to the height position of the tongue holding unit 24 is also easily accomplished by the loops 18a1 and 18b1.

How to get in FIG. 1 recognizes, the two loops 18a1 and 18b1 intersect below the hook plate 30. The length of the spacer 28 is therefore dimensioned so that both loops 18a1 and 18b1 safe place under the hook plate 30 place. In addition, a mark 32 is mounted on the top of the hook plate 30, in the in FIG. 3 illustrated embodiment in the form of intersecting grooves 34, the graph of the intersecting loops 18a1 and 18b1 graphically to make the wearer of the shoe 10 in the new Schnürungsart attentive.

In addition, the hook plate 30 adjacent those locations at which the loops 18 a 1 and 18 b 1 protrude below the hook plate 30, the largest radial extent beyond the spacer 28 on. These projections 30d are located in peripheral portions of the hook plate 30, which with the tongue longitudinal axis A an angle α of between about 30 ° and about 60 °, preferably about 45 ° include. By the cooperation of these projections 30d, the loops 18a1 and 18b1 are securely held under the hook plate 30. In addition, facilitate as in FIG. 4 illustrated Einlegeungsschrägen 30 d1 on the underside of the projections 30 d, the insertion of the loops 18 a 1 and 18 b 1 under the hook plate 30th

In the event that a wearer of the shoe 10 of the invention does not comply with the in FIG. 1 allows the fact that the tongue holding unit 24 also has a hook element on its side facing the toe 12b in the area 30c of the hook plate 30, that the lace 18 can also be bound in the conventional, purely crossed manner, like this in FIG. 2 is shown. At this time, the tongue holding unit 24 is used in the same manner as known from conventional high-heel tongue-holding shoes. Ie in this case would the two sections 18a, 18b of the lace 18 coming from the two opposite edges 14b and 14c cross below the spacer 28 and then proceed to the other of the slot edges 14c and 14b, respectively. In this case, the lower two projections 30 d ensure the secure retention of the lace 18 on the tongue holding unit 24.

It should also be added that in order to ensure a secure hold of the straps 18a1, 18b1 it is advantageous if the value of the radial extent E of the hook plate 30 protruding beyond the spacer element 28 is between approximately 4 mm and approximately 7 mm in the at least one section 30d of greatest radial extent , preferably about 5.5 mm.

It should also be added that the length L of the spacer 28 between the top of the abutment plate 26 and the underside of the hook plate 30 may be between about 2.5 mm and about 3.5 mm, preferably about 3.0 mm.
