Abstract

The invention relates to an ankle support comprising an one-piece shell having: a lateral shell section, a medial shell section which has an elongated reinforced zone for providing support in the ankle support such that by means of the elongated reinforced zone the lateral shell section is substantially less stiffer than the medial shell section, and a sole shell section connecting the lateral shell section and the medial shell section, wherein the medial shell section comprises a medial edge configured to run upwards from the sole shell section along the medial side of lower leg and defining an open recess in the medial shell section for the medial malleolus.

Claims (35)

1 . An ankle support including a one-piece shell comprising:

a lateral shell section;

a medial shell section that is larger than the lateral shell section, the medial shell section including an elongated reinforced zone for providing support in the ankle support, wherein the lateral shell section is less stiff than the medial shell section;

a sole shell section connecting the lateral shell section and the medial shell section; and

an elastic cover;

wherein:

the medial shell section includes a medial edge configured to extend upwards from the sole shell section along the medial side of lower leg and defining an open recess in the medial shell section for receiving the medial malleolus;

the lateral shell section includes a lateral edge configured to extend upwards from the sole shell section along the lateral side of the lower leg and defining an open recess in the lateral shell section for receiving the lateral malleolus;

the medial shell section extends farther upward from the sole shell section along the medial side of the lower leg than the lateral shell section extends from the sole shell section along the lateral side of the lower leg, the elongated reinforced zone extending along at least a portion of the upward extent of the medial shell section;

at least a portion of the lateral edge is connected to the elastic cover; and

a portion of the elastic cover opposite the lateral edge is configured to be releasably connected to an upper portion of the medial shell section.

2 . The ankle support according to claim 1 , wherein at least a majority of a length of the lateral edge is connected to the elastic cover.

3 . The ankle support according to claim 1 , wherein the elastic cover comprises at least one strap section and a textile section, and wherein the textile section is more elastic than the at least one strap section.

4 . The ankle support according to claim 3 , wherein:

the at least one strap section comprises a first layer and a second layer arranged in a stacked configuration;

the first layer is less elastic than the textile section; and

the second layer is formed by the textile section.

5 . The ankle support according to claim 3 , wherein the textile section comprises a double folded textile.

6 . The ankle support according to claim 5 , wherein an edge of the elastic cover, between the portion to be releasably connected to the upper portion of the medial shell section and the lateral edge, is provided by a fold line of the double folded textile of the textile section.

7 . The ankle support according to claim 5 , wherein an edge area of the elastic cover, extending between the sole section and the portion of the elastic cover to be releasably connected to the upper portion of the medial shell section, is provided by the at least one strap section.

8 . The ankle support according to claim 7 , wherein a further edge area of the elastic cover, connected to the lateral edge of the lateral shell section, is formed by the at least one strap section.

9 . The ankle support according to claim 1 , further comprising:

at least one strap including two strap portions, wherein each of the two strap portions is connected to the sole shell section; or

two separate straps, wherein each strap is connected to the sole shell section;

wherein one of the two strap portions or one of the two straps is connected proximal to the sole shell section to the lateral shell section, and the other of the two strap portions or the other of the two straps is connected proximal to the sole shell section to the medial shell section.

10 . The ankle support according to claim 9 , further comprising at least one notch for guiding the at least one strap.

11 . The ankle support according to claim 1 , wherein circumferential edges of the one-piece shell are more flexible than the elongated reinforced zone of the medial shell section.

12 . The ankle support according to claim 1 , wherein the medial shell section and the lateral shell section together define a heel recess.

13 . The ankle support according to claim 12 , wherein the medial shell section and the lateral shell section merge into another at a position above the heel recess.

14 . The ankle support according to claim 1 , wherein in use, the one-piece shell is configured to leave a front part of a lower leg free such that the one-piece shell provides a semi-rigid frame defining an open instep space for receiving a foot and a lower leg of a user.

15 . The ankle support according to claim 1 , wherein the sole shell section comprises a reinforced sole zone that extends between the medial and lateral shell sections, and wherein the reinforced sole zone is stiffer than the lateral shell section.

16 . The ankle support according to claim 15 , wherein the elongated reinforced zone of the medial shell section is stiffer than the reinforced sole zone.

17 . The ankle support according to claim 1 , wherein the elongated reinforced zone of the medial shell section extends from or proximal to the sole shell section along the medial malleolus further upwards.

18 . The ankle support according to claim 1 , wherein the one-piece shell is made by multi-material injection molding.

19 . The ankle support according to claim 1 , wherein the lateral shell section comprises at least one zone that is stiffer than another zone of the lateral shell section and is less stiff than the elongated reinforced zone of the medial shell section.
