Abstract
An ankle foot orthotic foot brace device includes a primary elongated resistance member attached to and extending from a base disposable under a user's foot. The primary resistance member includes means for attachment to the user's leg, and is deflectable through a deflection range and resilient or elastic to provide an initial resistant force to pivoting of the user's foot with respect to user's leg. A secondary elongated resistance member is engagable by the primary resistance member within a subsequent or distal portion of the deflection range of the primary resistance member. Also included is means for intercoupling the secondary resistance member to the primary resistance member during the subsequent portion of the deflection range of the primary resistance member.
Claims22
An ankle foot orthotic brace device, comprising:
- a) a base, engagable by a user's foot;
- b) a rearward elongated resistance member, having one end attached to the base and extending to an opposite end attachable to the user's leg, being deflectable through a deflection range and resilient to provide a primary resistant force to deflection of the rearward member with respect to the base and pivoting of the user's foot with respect to user's leg;
- and
- c) a forward elongated resistance member disposed forwardly of the rearward member and engagable by the rearward member within a subsequent deflection range of the rearward member in a forward direction, and spaced apart from the rearward resistance member forwardly with respect to the rearward member along an entire length of the forward resistance member;
- and
- d) the forward and rearward resistance members include a composite material with a fiber in a resin matrix.
An ankle foot orthotic brace device, comprising:
- a) a foot plate configured to be disposed under a user's foot and between the user's foot and a shoe worn on the user's foot;
- b) a rearward elongated spring having a proximal end attached to the foot plate and extending substantially vertically to an opposite end configured to be coupled to the user's leg;
- c) the rearward spring being flexible and deflectable during use through a deflection range and resilient or elastic to provide a resistance force to deflection and movement of the rearward spring with respect to the foot plate and between the user's foot and leg;
- d) a forward elongated spring having a proximal end attached to the foot plate and extending substantially vertically therefrom to a distal end configured to be engaged by the rearward spring;
- e) the forward spring being flexible to deflect and resilient or elastic to provide additional resistance force to deflection and movement when engaged by the rearward spring;
- f) the forward spring being spaced-apart forwardly with respect to the rearward spring from the proximal end at the foot plate to the distal end and positioned so that the rearward spring engages the forward spring during a distal portion of the deflection range;
- and
- g) the forward and rearward springs include a composite material with a fiber in a resin matrix.
