Patent Description:
Knee joint is one of the j oints in the human body that has a high load-bearing capacity and a complex structure. Knee joint diseases often occur in daily life, leading to limited human movement and seriously reducing the quality of life. In order to alleviate the damage of the knee joint diseases to the human body and improve the quality of life, a knee-joint brace is provided in the existing technologies, with which a support structure (such as a support arm) is arranged on the periphery of the knee joint to assist in supporting the knee joint associated bones, whereby assisting in fixing and supporting the knee joint. Therefore, the knee-joint brace can provide great protection and support for those people with knee joint discomfort, can reduce the pain and discomfort of the knee joints, and can provide walking support to certain extent for those people with walking disabilities, thereby reducing the condition of limited human movement and improving the quality of their lives.

However, for most of those patients with knee-joint diseases, their self-care abilities are greatly limited, and they often have problems in wearing and removing the knee-joint braces.

<CIT> discloses a belt buckle device including a tongue piece connected to an end of a belt extending in a longitudinal direction and a hook member configured to be selectively connected to the tongue piece by engaging a first lateral bar of the tongue piece in a hook opening defined by a hook portion thereof. A longitudinal dimension between the free end of the tongue piece and a base end side of the first lateral bar is substantially equal to or smaller than a width of the entrance of the hook opening, and the effective thickness of the first lateral bar is greater than the width of the entrance of the hook opening. Thus, the first lateral bar is held inside the hook opening as long as the tongue piece is kept in a flat position in a reliable manner. In particular, the first lateral bar can be freely introduced into the hook opening simply by raising the base end of the tongue piece while the first lateral bar is applied to the entrance of the hook opening so that the belt buckle device can be readily fastened even when the belt buckle device cannot be viewed from a proper viewing angle. Also, the belt buckle device can be readily fastened with a minimum dexterity requirement and very quickly.
