Abstract

The invention relates to an orthopedic device with
a joint with
a first joint element with
a first joint arm and a first positive-locking element, and
a second joint element that can be swivelled relative to the first joint element, said second joint element comprising
a second joint arm and a force application lever with a second positive-locking element, and a mechanical energy store, which is arranged between the force application lever and the second joint arm,

wherein the mechanical energy store can be charged and discharged by swivelling the first joint arm relative to the second joint arm when the positive-locking element engages with the second positive-locking element, wherein the device has a safety device which ensures that, irrespective of the position of the first positive-locking element and the second positive-locking element relative to one another, the two positive-locking elements can be engaged with one another in such a way that a force exerted by the charged mechanical energy store is transmitted from the second positive-locking element to the first positive-locking element.

First claim

1 . An orthopedic device which comprises
a joint with
a first joint element with
a first joint arm and a first positive-locking element, and

a second joint element that is swivellable relative to the first joint element, said second joint element comprising
a second joint arm, and
a force application lever with a second positive-locking element, and
a mechanical energy store which is arranged between the force application lever and the second joint arm,

wherein the mechanical energy store is chargeable and dischargeable by swivelling the first joint arm relative to the second joint arm when the positive-locking element engages with the second positive-locking element; and
a safety device which ensures that, irrespective of the position of the first positive-locking element and the second positive-locking element relative to one another, the two positive-locking elements are engageable with one another in such a way that a force exerted by the charged mechanical energy store is transmitted from the second positive-locking element to the first positive-locking element.

2 . The orthopedic device according to claim 1 , wherein the safety device is configured to rotate the positive-locking elements relative to one another when or after the two positive-locking elements are engaged with one another.

3 . The orthopedic device according to claim 2 , wherein the first positive-locking element and second-positive locking element comprise frontal projections and/or recesses and the safety device features a guide spindle that protrudes axially from one of the positive-locking elements, said guide spindle comprising frontal recesses and/or projections and being configured to engage with the respective other positive-locking element.

4 . The orthopedic device according to claim 3 , wherein the guide spindle is displaceable in the axial direction relative to the positive-locking element from which it protrudes axially, the guide spindle being configured in such a way that, upon axial displacement, the guide spindle is rotated about its longitudinal axis such that a torque is applied to the positive-locking element that engages with the frontal projections and/or recesses of the guide spindle.

5 . The orthopedic device according to claim 1 , wherein the first positive-locking element and/or the second positive-locking element has at least two partial positive-locking elements which can be moved independently of each other in the axial direction.

6 . The orthopedic device according to claim 5 , wherein the at least two partial positive-locking elements have the same projections and/or recesses which are arranged at an offset from each other in the circumferential direction.

7 . The orthopedic device according to claim 5 , wherein the at least two partial positive-locking elements are spaced apart from one another in the axial direction when the first positive-locking element and the second positive-locking element are not engaged.

8 . The orthopedic device according to claim 1 , wherein the first joint element is an upper body element and the second joint element is an upper leg element, and the orthopedic device further comprises a pelvic element, wherein the two positive-locking elements are configured to be brought in and out of engagement with one another by moving the upper body element relative to the pelvic element.

9 . The orthopedic device according to claim 2 , wherein at least some projections of the two positive-locking elements comprises an undercut toothing.

10 . The orthopedic device according to claim 1 , wherein the positive-locking elements are configured to be brought into engagement with each other by moving one of the positive-locking elements towards the other positive-locking element, which is mounted relative to the component on which it is arranged such that it is rotatable in one direction.

11 . The orthopedic device according to claim 9 , wherein all of the projections of the two positive-locking elements comprise an undercut toothing.
