Description
[0034] In the following, a number of embodiment examples of the invention will be explained in more detail with the aid of the accompanying figures.
[0035] They show
[0036] FIGS. 1 to 4—schematic representations of a dimensionally stable element with at least one fastening device,
[0037] FIGS. 5 to 7 schematic representations of various deflection eyelets,
[0038] FIGS. 8 to 11 schematic representations of various fastening devices,
[0039] FIGS. 12 to 14—schematic representations of different elements according to further embodiment example of the present invention,
[0040] FIGS. 15 to 17—schematic representations of different elements according to further embodiment example of the present invention and
[0041] FIG. 18—a representation of an orthopedic device according to a further embodiment of the present invention.
[0042] FIG. 1 depicts a dimensionally stable element 2 of an orthopedic device according to a first embodiment example of the present invention. It is a lower leg shell that is used, for example, for an ankle orthosis and can be arranged on a lower leg of a wearer of the orthosis. The dimensionally stable element 2 features multiple fastening devices 4, which protrude outwards from the base body of the dimensionally stable element 2. The shape and configuration of the fastening devices 4 are described in more detail below. A deflection eyelet 8 is arranged on the top fastening device 4 via a connection element 6, which is designed in the shape of a very short cord.
[0043] FIG. 2 shows a dimensionally stable element 2, which also comprises a plurality of fastening devices 4. These are designed as a single element. Each fastening device 4 has a feed-through 10, the feed-throughs 10 and thus the fastening devices 4 being arranged equidistantly in the embodiment example shown. In FIG. 2 there are two deflection eyelets 8, each of which is connected to the fastening devices 4 via a connection element 6. Each of the connection elements 6 extends through a feed-through 10, which is, however, only schematically indicated in FIG. 2.
[0044] FIG. 3 shows the dimensionally stable element 2 from FIG. 2 from a different perspective. In FIG. 3, it is clear that the two connection elements 6, by each of which one of the two deflection eyelets 8 is attached, extend into one of the feed-throughs 10.
[0045] FIG. 4 shows a different configuration. Here, the dimensionally stable element 2 is part of a foot section of an ankle orthosis. The deflection eyelet 8 is connected via the connection element 6 to a fastening device 4, which comprises a feed-through 10 through which the connection element 6 passes.
[0046] FIGS. 5 to 7 each show a deflection eyelet 8 through which a strap can be guided and deflected. Each of the deflection eyelets 8 exhibit an eyelet feed-through 12, which is designed differently in each of the FIGS. 5 to 7. In FIG. 5, the eyelet feed-through 12 features a slit 14 which, the embodiment example shown, extends across the entire longitudinal extension of the eyelet feed-through 12. The slit 14 has a width that is greater than a diameter of a connection element 6 that can be guided through the eyelet feed-through 12. At the lower end of the eyelet feed-through 12 in FIG. 5 is a section 16 that exhibits a larger diameter than the rest of the eyelet feed-through 12. In FIG. 5, a connection element 6, which has an anchor at its end and is guided through the eyelet feed-through 12, can be displaced upwards until the anchor is partially, but preferably completely, accommodated in this section 16. From this point onwards, it is not possible to pull the connection element 6 further in this direction through the eyelet feed-through 12.
[0047] FIG. 6 shows a similar shape, which only differs from the shape of eyelet feed-through 12 shown in FIG. 5 in that it does not have a slit. FIG. 7, on the other hand, depicts an eyelet feed-through 12 in which the section 16 can be clearly seen. The eyelet feed-through 12 in FIG. 7 also features the slit 14 and as such is open at the top. The slit 14 also has a greater width in the section 16, which has a larger cross-section in comparison to the rest of the eyelet feed-through 12. A connection element 6, at the end of which an anchor is located, can therefore be inserted from above through the slit 14 into the eyelet feed-through 12. Only when a tensile force acts on the connection element 6 is it no longer possible, due to the resulting friction, to remove connection elements 6 from the eyelet feed-through 12.
[0048] FIGS. 8 to 11 depict different embodiments of a fastening device 4. FIG. 8 shows a first configuration in which the feed-through 10 features a slit 14, i.e. it is designed to be open at the top. A section 16 can be seen inside the feed-through 10, the former having a larger cross-section than the rest of the feed-through 10. This section is configured to completely accommodate an anchor, which is located at an end of a connection element 6. In order to be able to position this anchor in the section 16, the fastening device 4 has an insertion opening 18, the dimensions of which are such that the anchor can be completely accommodated.
[0049] FIG. 9 shows a fastening device 4 in which the feed-through 10 has the slit discussed above. It is possible to see the section 16 with the larger cross-section at the rear of the fastening device 4 in FIG. 9. The fastening device 4 shown in FIG. 10 differs from the fastening device 4 in FIG. 9 in that the feed-through 10 does not feature a slit.
[0050] FIG. 11 shows a fastening device 4 which is very similar in function and design to the fastening device 4 shown in FIG. 8. It is designed merely as a raised element and is consequently placed on a base body of a dimensionally stable element.
[0051] The feed-through 10 features the slit 14 and the insertion opening 18 is shown in the rear region, through which an anchor can be inserted into the fastening device 4 and then into the section 16.
[0052] FIGS. 12 to 14 schematically depict a different embodiment. FIG. 12 first shows a connection element 6 that has a first end 20 with a first anchor 22 and a second end 24 with a second anchor 26. FIG. 12 also shows another form of the deflection eyelet 8, which is in the form of a hose. The two ends 20, 24 of the connection element 6 are arranged to interact with a fastening device 4.
[0053] This is shown in FIG. 13. The connection element 6 extends through the deflection eyelet 8, which is shown by the dashed lines. The two ends 20, 24 of the connection element 6 are inserted into a first feed-through 10 and into a second feed-through 28, so that the connection element 6 forms a loop. FIG. 14 shows the situation in a schematic top view. The ends 20, 24 of the connection element 6 are arranged in the fastening device 4 and cannot be seen. A strap 30 is placed around the deflection eyelet 8.
[0054] FIGS. 15 to 17 show a slightly different embodiment, which differs from the embodiment in FIGS. 12 to 14 in particular in that the deflection eyelet 8 not only includes the tunnel through which the connection element 6 is guided, but itself forms an eyelet through which the strap 30 is guided.
[0055] FIG. 18 shows an orthopedic device in the form of an ankle orthosis. It has a first dimensionally stable element 2 in the form of a foot section, which is arranged on a foot of a wearer of the orthopedic device. It also has a second dimensionally stable element 2 in the form of a lower leg section, which can be mounted on a lower leg of the wearer. Both dimensionally stable elements 2 each have at least one fastening device 4, each of which has a feed-through 10. A connection element 6 is or can be guided through said feed-through. A deflection eyelet 8 is arranged on each of the depicted connection elements 6.
