Ankle-foot support assistive device

Abstract

This disclosure provides an ankle and foot support assistive device, comprising: a composite shoe upper; a composite sole attached to the bottom of the composite shoe upper; and a skeleton, which includes components such as a base, an anchor, a joint axis, a support column, a balancer, a biomimetic vertebra, and a lateral brace; through the coordinated operation of the components of the skeleton, stress can be distributed and locked in real time, solving the problems of uneven support and limited rigidity of traditional ankle and foot braces during dynamic movement. Furthermore, the skeleton can simulate biological ligaments, maintaining flexibility during normal walking and providing rigid protection through structural interlocking in the event of a rollover.

Claims

1. An ankle-foot support assistive device, comprising: A composite shoe upper includes an outer shell and an inner lining, the inner lining being disposed inside the outer shell; a composite sole is attached to the bottom of the composite shoe upper; and a skeleton is disposed between the outer shell and the inner lining, the skeleton including a base, an anchor, a joint axis, a support column, a balance component, a bionic vertebra, and a lateral protective gear; the base has a bottom wall and a surrounding wall extending upward from the bottom wall; the anchor is attached to the rear side of the base, the anchor has a longitudinally extending load-bearing portion and a connecting portion extending horizontally forward from both sides of the load-bearing portion, the connecting portion being attached to the outer side of the surrounding wall, a pivot block is provided on the outer side of the top of the load-bearing portion, and a first limiting groove is provided on the inner side of the top of the load-bearing portion; the joint axis is transversely disposed on the pivot block; the bottom end of the support column forms a pivot lug and is pivotally connected to the joint axis, so that the support column can be pivotally connected to the joint axis. The axis pivots relative to the anchor in a back-and-forth direction. The top of the support column has a longitudinally extending track and a slot extending laterally through the track. The bottom of the balancer has a longitudinally extending slide rail, which allows the balancer to slide up and down with the support column. The balancer also has a slot extending laterally through the slide rail. A second limiting groove is formed on the front side of the balancer. The bottom of the bionic vertebra forms a first limiting block, and the top of the bionic vertebra forms a second limiting block. The first limiting block is connected to the first limiting groove, and the second limiting block is connected to the second limiting groove. One end of the lateral guard forms an insert plate, which is inserted into the slot of the balancer and the slot of the support column. The lateral guard supports one side of the lower leg.

2. The ankle and foot support assistive device as described in claim 1, wherein, A longitudinally extending groove is formed on the front side of the support column, and a groove connected to the second limiting groove is formed on the front side of the balance member. When the support column pivots forward, the balance member squeezes the bionic vertebra. When the support column pivots backward, the balance member pulls the bionic vertebra. The groove of the support column and the groove of the balance member accommodate the bionic vertebra.

3. The ankle and foot support assistive device as described in claim 1, wherein, The frame further includes a shoe shield, which is located between the outer shell and the inner lining. A C-shaped mounting wall is provided on the front side of the shoe shield. A C-shaped mounting wall is provided on the outer side of the lateral support. The ankle and foot support device further includes a shoelace fastening knob, which is located on the composite shoe body and is connected to the mounting wall of the lateral support or the mounting wall of the shoe shield.

4. The ankle and foot support assistive device as described in claim 3, wherein, The outer side of the surrounding wall is provided with a plurality of rope hooks, and the front side of the lateral protective gear is provided with a rope hook. The shoelace fastening knob is composed of a turntable and a plurality of ropes. The turntable is rotatable and is provided on the mounting wall of the lateral protective gear or the mounting wall of the shoe shield. The turntable has a built-in gear and is connected to the ropes. The ropes are connected in series to the rope hook of the base and the rope hook of the lateral protective gear.

5. The ankle and foot support assistive device as described in claim 1, wherein, The joint is provided with a non-circular joint hole, and the base is provided with a non-circular joint block corresponding to the joint hole, and the joint hole is engaged with the joint block.

6. The ankle and foot support assistive device as described in claim 1, wherein, The base has multiple openings.

7. The ankle and foot support assistive device as described in claim 1, wherein, The support column is H-shaped, the balancing component is T-shaped, the biomimetic vertebra is I-shaped, and the base has a U-shaped cross-section.

8. The ankle and foot support assistive device as described in claim 1, wherein, The lining is made of a multi-layer structure, consisting of a stress-dispersing layer, an energy-absorbing layer, and a skin-friendly and hygienic layer.

9. The ankle and foot support assistive device as described in claim 1, wherein, The composite sole includes an outsole and an insole placed on the bottom wall, the surrounding wall being located between the outer shell and the inner lining, and the outsole being made of abrasion-resistant rubber.

10. The ankle-foot support assistive device as described in claim 9, wherein, The insole is made of a multi-pad structure, which consists of a wedge-shaped foot pad, an arch support pad, and a heel shock-absorbing pad.
