Abstract
A sandal having detachable strap fastening, comprising a sole, at least one strap, and at least two anchor buckles, in which the sandal is modularly constructed and can be easily assembled and disassembled. The sole and the at least one strap are connected to each other by guiding the at least one strap through apertures in the sole, and that each end of the at least one strap is secured to an aperture in the sole by means of one of the anchor buckles. The at least two anchor buckles function by friction-locking and can be opened manually after closing and are detachable from the at least one strap.
Claims
1. A sandal having detachable strap fastening, comprising a sole (1), at least one strap (2), and at least two anchor buckles (5), in which the sandal is modularly constructed and can be easily assembled and disassembled, in which the sole (1) and the at least one strap (2) are connected to each other by guiding the at least one strap (2) through apertures (5) in the sole (1), and that each end of the at least one strap (2) is secured to an aperture (5) in the sole (1) by means of one of the anchor buckles (5), characterized in that the (at least two) anchor buckles (4) function by friction-locking and can be opened manually after closing and are detachable from the at least one strap (2).
2. The sandal according to claim 1, wherein the anchor buckles (3) are configured to be fastened to the strap (2) ends, thus preventing the at least one strap (2) from slipping through the aperture (5) and affixing the at least one strap (2) to the sole (1).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0049] FIG. 1 schematically shows an embodiment example of the sandal in which it is disassembled into its individual components, i.e. is available as a kit. Said kit comprises a sole 1 with the integrated apertures 5, a strap 2, a simple anchor buckle 3 and a cam buckle 4 with an open long clamping lever 8
[0050] FIG. 2 shows the same embodiment example in the assembled state. Here the strap 2 is guided through all apertures 5 and anchored at one end with the simple anchor buckle 3 to one of the apertures 5 and with the other end, after passing through another one of the apertures 5, turned over and fastened to the strap 2 with the cam buckle 4.
[0051] FIG. 3 shows a fully assembled embodiment example where the sole 1 consists of a softer sub-component 6 for cushioning and shaping the footbed and a harder sub-component 7, both forming the apertures 5 and shaping the outsole to provide abrasion resistance and puncture resistance. For each sandal, right and left, there is only one strap 2 used each. Both ends of the strap 2 are guided through apertures 5 and are folded back to be attached by a slidable cam buckle 4 each. In this embodiment there are two cam buckles 4 used for one of the soles 1, right or left. The cam buckles 4 are designed with two clamping levers, while in each case the strap end is fastened to one of the clamping levers and, after building the loop through the aperture 5, the strap 2 is guided under the opened second clamping lever and afterwards securely locked at a designated position. In this embodiment it is possible to adjust the strap fastening to the size and shape of the user's foot via the two slidable cam buckles 4.
[0052] FIG. 4 shows a slidable cam buckle 4 with two clamping levers 8 and 9. Both clamping levers 8 and 9 are in an open state. The cam buckle 4 is ready to be used to compose a sandal or in case of its end of use it is ready to be recycled, consisting of three sub-components all made of the same material and thus building a buckle of single-variety.
[0053] FIG. 5 shows the same slidable cam buckle 4 as shown in FIG. 4 additionally having a strap 2 attached to the short clamping lever 9, which is closed. The long clamping lever 8 is in an open state.
[0054] FIG. 6 shows the same slidable cam buckle 4 as shown in FIG. 5 with the one end of the strap 2 affixed by the short clamping lever 9 and additionally guided under the open long clamping lever 8. This shows the attaching principle by forming a loop which must be guided through one of the apertures 5 in the sole 1 to attach the strap 2 to the sole 1. In this configuration the cam buckle 4 can be slid on the strap 2 and the loop can be reduced or enlarged. When adjusted to the right fit, the long clamping lever 8 will be closed by pushing it down and thus locking the strap 2 by friction-locking at the desired position.
