Description

Joint bracket adjustable device

The present invention relates to a stent, and more particularly to an adjustable stent device.

Generally, when a limb is injured, especially near a joint (such as a knee), in order to avoid re-injury or deterioration of the injured part due to excessive activity during the treatment/rehabilitation process, it is often used with an auxiliary device. Limiting the range of relative activities of the limbs for protection purposes; however, it can be understood that such accessories can also be used for body posture correction of the human body, such as the joint bracket adjustable device disclosed in TWM336776 and TWM414216. class.

In the TWM336776 patent, the positioning method is inserted into the positioning hole through the positioning pin to achieve the purpose of adjusting the positioning; however, when used for the elderly and young children who are weaker in the body, because the activity itself is less convenient and the manipulation is not Accurate, often can not be quickly and accurately inserted and removed, so that the joint bracket can not be properly positioned, it can not effectively achieve the purpose of the original protection, there are shortcomings to be improved.

The above-mentioned shortcoming is improved by the TWM 414216 patent, which adopts a positioning method in which the positioning pin is engaged with the tooth concave, wherein the opening direction of the tooth concave is toward the center of the disk body, and the positioning pin is normally oriented away from the disk through the elastic member. The center of the body moves so that the joint bracket can remain positioned. When the user wants to adjust the angle, the adjustment is moved by pressing the push button. However, when During the movement of the user, since the pressing button protrudes radially from the outside of the disk, the pressing button is often easily accidentally collided, so that the positioning pin is separated from the tooth concave, and cannot be securely positioned, but is safe. Doubt, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive joint bracket adjustable device to solve the above problems.

The main object of the present invention is to provide an adjustable joint bracket device, which can easily move the adjusting mechanism to adjust the angle of the desired movement, and considers the occurrence of an unintended collision, changing the direction of the positioning and matching the magnetic attraction mode. The positioning component and the base have better and stable positioning effects, thereby improving the safety and reliability during use.

To achieve the above object, the present invention provides a joint bracket adjustable device comprising a base, two connecting members and a positioning mechanism. The base has a center and two opposite and spaced side walls, at least one of the side walls having a plurality of concavities disposed in an arcuate configuration and communicating with respect to the center, the openings of the concavities being away from the center. The two connecting members are respectively connected to the base, and at least one of the two connecting members is pivotally connected to the base, and the connecting members are respectively connected to the limbs of the human body. The positioning mechanism has a fixing member disposed between the two side walls, and at least one adjusting mechanism connected to the base, each adjusting mechanism has a positioning component for external operation and movable around the center, the positioning component can be Selectively moving radially to engage or disengage from a concavity, at least one of the positioning assembly and the fixing member is magnetic and magnetically attracts the other, thereby causing the positioning assembly to move toward the center The trend.

Moreover, one of the connecting members 3 is fixed between the two side walls 25, and the other connecting member 3 is pivotally connected to the base 2. More specifically, each of the pieces 6 is provided with the plurality of teeth. a recess 26 and a wing portion 61 extending radially, each of the wing portions 61 is fixedly coupled to the connecting member 3, and the other connecting member 3 is pivotally connected to the pivot shaft 231, and along the pivot shaft 231 In the direction of extension, the outline of each of the sheets 6 is a "9" shape.

Further, in this embodiment, each of the adjusting mechanisms 42 further includes a moving base 421 pivotally connected to the pivot shaft 231, and each of the moving bases 421 spans the first and second components 21, 22, The two positioning components 5 are movably disposed on the two moving seats 421 . In use, the positioning component 5 is first moved away from a tooth recess 26 to release the positioning state of the phase-locking card, and then the moving seat 421 and the positioning component 5 are rotated around the center 24 to rotate to a desired position. To position, only the hand is released, and the positioning assembly 5 can be moved relative to the moving seat 421 to be engaged with a tooth recess 26, so that the positioning mechanism 4 is in a positioning state. Preferably, the base 2 is separately provided There is a plurality of angular scales 27, which respectively correspond to the plurality of dents 26. During the rotation of the movable seat 421, the user can quickly and accurately adjust to the range of yaw amplitudes to be set by visual observation. More preferably, each of the movable seats 421 is further provided with an identification hole 422.
