Abstract

A joint rehabilitation device consists of a first frame, a second frame, a control lever, an elastic member and an engaging structure. The first frame defines a limiting slot by a first and a second side board to be inserted by the ratchet of the second frame, and the limiting slot is arranged transversely by a central shaft pivotally connected with the ratchet center and a first shaft pivotally connected with the control lever. The first and second side boards are further provided with an angle adjustment hole set for clutching the blocking bolt; one end of the control lever is provided with teeth for engaging the ratchet, and the other end is protruded from the limiting slot to form a toggle part for force application; the elastic member provides preset resilience to the control lever such that the teeth and the ratchet are ready for engagement so as to control the second frame rotation and positioning along one direction toward the blocking bolt relative to the central shaft as the fulcrum; the engaging structure comprises a buckling block at the first frame such that when the toggle part forces the teeth to disengage the ratchet, the buckling block switchably supports the control lever positioned at the position so as to enable the second frame to perform idle return relative to the central shaft as the fulcrum.

Description

Joint rehabilitation device

The present invention relates to a joint rehabilitation device having a fixed or limited joint angle of motion.

Press, the conventional joint rehabilitation device is like the "Knee joint fixture adjustment device", No. 097220383 "Joint support adjustment device", No. 096210485 "Knee joint fixator positioning structure", etc. As shown in the case, however, the structure of the patents is quite complicated, resulting in inefficient processing costs and inconvenient operation.
The present inventors have developed the present invention by continually conceiving and innovating in view of the shortcomings of the prior patents.

The present invention provides an articulation device comprising at least:
a first frame body, wherein the first side plate and the second side plate define a limiting slot, wherein the limiting slot respectively has a middle shaft and a first shaft, and the first and second side plates are further provided with an angle adjusting hole group For providing a bolt latch;
a second frame, the ratchet wheel is inserted into the limiting slot, the center of the ratchet has a middle hole for the middle shaft, and the outer peripheral ring of the ratchet is provided with an external tooth portion;
a control rod is inserted into the limiting slot, and is provided with a latching tooth at the one end edge thereof for engaging the external tooth portion of the ratchet, and a protruding end portion for projecting the limiting slot at the other end edge to form a pulling portion for applying force. Further, a first hole for the first shaft to be pivoted is disposed between the latch and the trigger portion;
An elastic element is mounted in the limiting slot so as to provide a preset elastic force to the control rod, so that the engaging teeth have the potential to engage the outer teeth of the ratchet at any time, thereby controlling the second frame to be only supported by the central axis. And a buckle structure, wherein the buckle body is mainly provided with a buckle block in the first frame body, and the support lever is configured to be switched when the clamp portion forces the card tooth to be away from the ratchet position. At this position, the second body can be vacant with the central axis as a fulcrum.
Therefore, the configurations of the present invention can greatly reduce the structural configuration of the pre-existing patent application, so as to achieve economical principles and novel functions under the substantial saving of labor and efficiency, in order to remove the patent before the disclosure. The problem of the case, and can effectively improve the convenience of handling, is indeed a novel technology of joint rehabilitation device.
