Abstract
Official abstract text for this publication.
An exoskeleton for supporting an arm of a user includes a torso attachment device, a bracket which is connectable to the torso attachment device, a lifting rod which is connectable to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket, a cantilever for supporting the arm of the user which is releasably connectable to the arm of the user, a ratchet mechanism that connects a first end of the lifting rod to a first end of the cantilever, and a blocking device. The ratchet mechanism is adjustable by the blocking device from a release position into a blocking position where, in the release position, the cantilever is pivotable relative to the lifting rod and where, in the blocking position, a pivoting movement of the cantilever relative to the lifting rod is blocked.
First claim
Opening claim text (preview).
What is claimed is: 1. An exoskeleton for supporting an arm of a user, comprising: a torso attachment device for releasably connecting the exoskeleton to a torso of the user; a bracket which is connectable to the torso attachment device; a lifting rod which is connectable to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket; a cantilever for supporting the arm of the user which is releasably connectable to the arm of the user; a ratchet mechanism, wherein the ratchet mechanism connects a first end of the lifting rod to a first end of the cantilever; and a blocking device, wherein the ratchet mechanism is adjustable by the blocking device from a release position into a blocking position, wherein in the release position the cantilever is pivotable relative to the lifting rod about an axis of rotation in a first direction of rotation and in a second direction of rotation, wherein in the blocking position of the cantilever is blocked from being pivotable relative to the lifting rod is blocked in the second direction of rotation but not in the first direction of rotation, and wherein, when pivoting the cantilever in the first direction of rotation, the lifting rod is moved in an upward direction, and, when pivoting the cantilever in the second direction of rotation, the lifting rod is moved in a downward direction. 2. The exoskeleton according to claim 1 further comprising a coupling rod having a first end and a second end, wherein the coupling rod is rotatably connected to the cantilever by the first end and to the lifting rod via a compensating mechanism by the second end. 3. The exoskeleton according to claim 2 , wherein the compensating mechanism comprises a slot at the second end of the coupling rod and a pivot bearing on the lifting rod and wherein the pivot bearing is disposed in the slot. 4. The exoskeleton according to claim 2 , wherein the compensating mechanism comprises a slotted guide disposed between the second end of the coupling rod and the lifting rod. 5. The exoskeleton according to claim 2 , wherein the compensating mechanism comprises a sector gear and a rack and wherein the sector gear is rotatably connected to the lifting rod such that teeth of the sector gear mesh with teeth of the rack. 6. The exoskeleton according to claim 5 , wherein the lifting rod and the rack are configured as a piston-cylinder unit. 7. The exoskeleton according to claim 1 further comprising an actuating mechanism for the blocking device, wherein the actuating mechanism is operable by a head movement of the user.
