Description
[0033] In the Drawings:
[0034] FIG. 1 is a partially-sectioned perspective view of a first exemplary embodiment of a shoe insert according to the invention;
[0035] FIG. 2 is a plan view of an exemplary embodiment of the damping layer of the shoe insert according to the invention;
[0036] FIG. 3 is a cross section of a second embodiment of a shoe insert according to the invention; and
[0037] FIG. 4 is a partial section from a shoe insert according to the invention together with a fragrance container.
[0038] FIG. 1 shows a first exemplary embodiment of a shoe insert according to the invention in a schematic three-dimensional view, wherein the individual layers are shown partially cut away for a better understanding of the selected layer structure.
[0039] According to FIG. 1, the first exemplary embodiment of the shoe insert 1 according to the invention comprises a cover layer 2 as the uppermost layer of the shoe insert 1 and a damping layer 3 in combination with a further fabric cover 5 which is arranged as an additional layer below the damping layer 3 and completely covers its underside 32 in the depicted embodiment. In the depicted embodiment, the damping layer 3 has a depression 31 on its upper side 30, in which the absorbent core 4 is accommodated, wherein the cover layer 2 is arranged above, and covers, the damping layer 3 and the absorbent core 4, wherein in FIG. 1 part of the cover layer 2 and the damping layer 3 have been cut away for better illustration.
[0040] As can also be seen from FIG. 1, the depression 31 for receiving the absorbent core 4 is formed by a circular punched-out portion on the upper side 30 of the damping layer 3. In the depicted exemplary embodiment according to FIG. 1, the layers 2, 3 and 5 are in this case based substantially on the shape and dimensions of a footbed of a left shoe, wherein the shoe insert in the depicted embodiment is designed as an insole. In the depicted embodiment, the individual layers 2, 3, 5 lie on top of one another and are inseparably connected to one another, for example, by providing an adhesive bond using neoprene adhesive.
[0041] FIG. 2 shows the design of the damping layer 3 according to the invention, wherein the damping layer 3 in the depicted embodiment has a depression 31 in the form of a circular punched-out portion 33 on the upper side 30 of the damping layer 3. As can be seen from the comparison of FIGS. 1 and 2, both the position and the dimensions of the depression 31 on the surface 30 for receiving the absorbent core 4 can be varied according to the invention. In particular, the depression 31 and thus the absorbent core 4 can be positioned in regions of the shoe insert 1 in which, due to the geometry of the arch of the foot of the shoe wearer, a low local pressure is to be expected during use.
[0042] FIG. 3 shows a second exemplary embodiment of a shoe insert 1 according to the invention, wherein the shoe insert 1 comprises a cover layer 2 and a damping layer 3 as well as an additional layer formed by the fabric cover 5 below the damping layer 3, which completely covers the underside 32 of the damping layer 3. As can be seen from the cross section in FIG. 3, the damping layer 3 has a depression 31 on its upper side 30, in which the absorbent core 4 is accommodated. In the depicted exemplary embodiment, the cover layer 2 completely covers the damping layer 3 but, in the region of the absorbent core 4, it has a valve device formed, by way of example, by a hole-shaped recess 21, via which the absorbent core 4 can be supplied with liquid fragrances 8 (not shown in FIG. 3). The exemplary embodiment in FIG. 3 of the shoe insert 1 according to the invention has a middle region 34 and edge regions 35 and 36, wherein the damping layer 3 in the edge regions 35 and 36 tapers from a maximum thickness in the middle region 34 to a minimum thickness in the region of the peripheral edge of the shoe insert 1 according to the invention, and the edges 35 and 36 of the damping layer 3 taper off all around to be thinner than in the middle of the damping layer 3.
[0043] As can also be seen from FIG. 3, the absorbent core 4 has substantially the dimensions of the depression 31 of the damping layer 3, wherein the absorbent core 4 is embedded in the depression 31. In the embodiment provided, the absorbent core 4 is designed to be minimally smaller than the dimensions of the depression 31 such that the absorbent core 4 can be glued into the depression 31 via an adhesive such as a neoprene adhesive.
[0044] FIG. 4 shows parts of a system according to the invention, comprising a left and right shoe insert 1 according to the invention and a fragrance container 7. For the sake of clarity, only a partial section of a shoe insert 1 according to the invention in combination with a fragrance container 7 is shown in FIG. 4, wherein the shoe insert 1 according to the invention is once again designed to have a cover layer 2 arranged on top, a subjacent damping layer 3, and a fabric cover 5 forming an additional layer. The absorbent core 4 for receiving the liquid fragrance 8 is arranged in the depression 31 of the damping layer 3. FIG. 4 shows the process of supplying the absorbent core 4 with the fragrance 8. In this case, the fragrance 8 is accommodated in the fragrance container 7 as a liquid and introduced into the absorbent core 4 via the container outlet 70 through the hole-shaped recess 21 in the cover layer 2. The drawing shows the application of a liquid drop of the fragrance 8 to the upper surface of the absorbent core 4. For this purpose, the container outlet 70 is adapted to the shape and dimensions of the hole-shaped recess 21 of the cover layer 2 such that accidental application of fragrance 8 to the cover layer 2 is prevented.
