Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The invention will now be described by way of example with reference to the accompanying drawings based on particularly preferred embodiments.

[0020] FIG. 1 shows a perspective side view of a shoe according to the invention.

[0021] FIG. 2 shows a front view of a shoe according to the invention.

[0022] FIG. 3 shows a cross-sectional view of a layer arrangement in the vicinity of a rivet.

DETAILED DESCRIPTION OF THE INVENTION

[0023] FIG. 1 shows a perspective side view of a shoe according to the invention. FIG. 2 shows a front view of a shoe according to the invention. The shoe 10 is, in the present case, a shoe 10 having a raised collar as common in, for example, hiking shoes, working shoes, and, in particular, in cut-resistant safety shoes. The shoe 10 has a profiled sole 12 made of rubber. The upper material 14 of the shoe 10 is, in the present example, at least in parts, made of fabric. The sole 12 is adjoined by a rand 16 adhesively bonded to the sole 12. The rand 16 is, in the present example, also made of rubber. The lateral reinforcement of the shoe 10 provided for by the rand 16 may completely surround the shoe 10 or may only be provided in sections. An edge 18 of the rand 16 is, in parts, designed so as to be undulated or serrated. The rand 18 is connected to the upper material by rivets 20. These rivets 20 are arranged in the wave crests 22 or spikes 24 of the undulated edge 18. In addition, the rand 16 may be sewn and/or adhesively bonded to the upper material 14.

[0024] The rivets 20 provide for a reliable connection between the rand 16 and the upper material 14. Furthermore, they provide for cut protection, for if a saw tool hits a rivet 20 it will bounce off with a high probability so that the foot of the wearer of the shoe 10 is protected and will remain uninjured. Moreover, the rivets 20 protect a possibly provided seam joining the rand 16 and the upper material 14 so that wear of the seams is reduced, and the shoe 10 remains durable in the area of the connection between the rand 16 and the upper material 14.

[0025] FIG. 3 shows a cross-sectional view of a layer arrangement in the vicinity of a rivet. A rivet 20 connects the rand 16 disposed on the outer side to the upper material 14. Between the rand 16 and the upper material 14, a connecting layer 34 may be provided. Further, a lining layer 26 and a cut protection layer 28 may be arranged on the inside of the upper material 14. In the present embodiment, the rivet 20 penetrates the upper material 16, the connecting layer 34, the rand 14, and the lining layer 26. A cut protection layer 28 disposed on the inside of the lining layer 26 is not penetrated by the rivet 20 in the present embodiment. However, this is nevertheless possible. Likewise, it is conceivable that the lining layer 26 is not penetrated by the rivet 20 either. It may likewise be contemplated that the arrangement of the lining layer 26 and of the cut protection layer 28 is reversed. Then again, it is possible that both layers are not penetrated by the rivet 20, or that only the layer arranged further to the outside or both are. The rivet 20 is provided with a flat head 30 on the inner side so that as little pressure as possible is exerted on the wearer's foot. On its outer side, the rivet 20 has a domed head 32 so as to provide for more engagement surface and mass with regard to the protection of the outer side of the shoe and for the purpose of cut protection.

[0026] The features of the invention disclosed in the above description, in the drawings as well as in the claims may be important for the realisation of the invention both individually and in any combination.
