Abstract
A hinge includes an upper hinge component and a lower hinge component. A cover plate is pivotally connected at first location point to the upper hinge component and at a second location point to the lower hinge component. First and second plates are pivotally connected at a third location point to the upper hinge component and at a fourth location point to the lower hinge component. The first plate is positioned between the cover plate and the upper and lower hinge components. The upper and lower hinge components are positioned between the first and second plates. The cover plate is mounted on an outer side of the hinge and the connection of the cover plate at the first location point rotates around the third location point and the connection of the cover plate at the second location point rotates around the fourth location point.
Claims19
A hinge having inner and outer sides opposed to one another, the hinge comprising:
- an upper hinge component;
- a lower hinge component;
- a cover plate pivotally connected at a first location point to the upper hinge component and at a second location point to the lower hinge component;
- first and second plates pivotally connected at a third location point to the upper hinge component and at a fourth location point to the lower hinge component, the first plate positioned between the cover plate and the upper and lower hinge components, and the upper and lower hinge components positioned between the first and second plates, wherein the cover plate is mounted on the outer side of the hinge such that the connection of the cover plate at the first location point rotates around the third location point and the connection of the cover plate at the second location point rotates around the fourth location point;
- and
- at least one friction plate pivotally attached to the upper hinge component at the third location point and to the lower hinge component at the fourth location point, the at least one friction plate arranged to create a friction surface between the upper and lower hinge components and the first plate or the second plate.
A hinge having inner and outer sides opposed to one another, the hinge comprising:
- an upper hinge component;
- a lower hinge component;
- a long linkage pivotally connected at a first location point to the upper hinge component and at a second location point to the lower hinge component;
- a short linkage pivotally connected at a third location point to the upper hinge component and at a fourth location point to the lower hinge component, the short linkage including a first plate positioned between the long linkage and the upper and lower hinge components and a second plate;
- a first rotation stop connected at a fifth location point between the first and second plates;
- wherein the long linkage is mounted on the outer side of the hinge, the connection of the long linkage at the first location point rotates around the third location point in a first direction, and the connection of the cover plate at the second location point rotates around the fourth location point in a second direction opposite the first direction.
An orthopedic device comprising:
- a hinge having inner and outer sides opposed to one another, the hinge including:
- an upper hinge component;
- a lower hinge component;
- a cover plate pivotally connected at a first location point to the upper hinge component and at a second location point to the lower hinge component;
- a first and second plate pivotally connected at a third location point to the upper hinge component and at a fourth location point to the lower hinge component, the first plate positioned between the cover plate and the upper and lower hinge components and the upper and lower hinge components positioned between the first and second plates, wherein the cover plate is externally mounted on the hinge and the connection of the cover plate at the first location point rotates around the third location point and the connection of the cover plate at the second location point rotates around the fourth location point;
- and
- a first rotation stop connected at a fifth location point between the first and second plates.
A hinge having inner and outer sides opposed to one another, the hinge comprising:
- an upper hinge component;
- a lower hinge component;
- a cover plate pivotally connected at a first location point to the upper hinge component and at a second location point to the lower hinge component;
- first and second plates pivotally connected at a third location point to the upper hinge component and at a fourth location point to the lower hinge component, the first plate positioned between the cover plate and the upper and lower hinge components, and the upper and lower hinge components positioned between the first and second plates, wherein the cover plate is mounted on the outer side of the hinge such that the connection of the cover plate at the first location point rotates around the third location point and the connection of the cover plate at the second location point rotates around the fourth location point;
- and
- a condyle plate secured to and located adjacent the second plate.
