Abstract
The invention relates to a device producing a stance flexion. This goal is achieved according to the invention by virtue of the fact that in the initial position of the multi-element joint system one element (joint element) can execute two movements with respect to the other elements (joint elements) connected to it, with at least one movement, after its initiation, at least predominantly blocking the other possible movement.
Claims18
A pivot device for use between parts of an orthopedic aid comprising:
- a multi-element kinematic joint chain having at least four joint elements;
- rotation means connecting respective ones of said joint elements, wherein the elements connected with one another have a common rotational axis, and said rotation means are positioned parallel to one another,
- wherein said joint chain, in a first position representing full extension, provides two different modes of joint flexion,
- wherein, in said first position, a first element of said joint elements executes a first type of movement and a second type of movement with respect to other elements of said joint elements connected to a first side of said first element,
- wherein said first type of movement, when initiated before said second type of movement, blocks said second type of movement and said second type of movement, when initiated before said first type of movement, blocks said first type of movement.
2 more elements
A pivot device for an orthopedic aid, comprising:
- first and second limb members;
- first and second rods positioned between said first and second limb members;
- at least four joint elements connecting said first and second rods to said first and second limb members, each of said joint elements having parallel rotational axes;
- and
- means for moving at least one of said four joint elements in at least two different movements with respect to a remaining three joint elements of said four joint elements, an initiation of a first of said two different movements immediately blocking execution of a second of said two different movements.
