Abstract
Official abstract text for this publication.
An exoskeleton for supporting an arm of a user includes 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, and a spring element. A force is exertable on the cantilever and the lifting rod by the spring element.
First claim
Opening claim text (preview).
The invention claimed is: 1. An exoskeleton for supporting an arm of a user, comprising: a torso attachment device releasably connecting the exoskeleton to a torso of the user; a bracket connected to the torso attachment device; a lifting rod connected 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 configured to support an upper arm of the user, wherein the cantilever is releasably connectable to the upper arm of the user; and a spring element configured to exert a force on the cantilever and the lifting rod so as to assist in supporting a load lifted overhead by the user while the upper arm of the user is supported by the cantilever which simultaneously moves the lifting rod in the first 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.
