Description

Law motivation

The present invention is a kind of motive, especially a kind of motive that provides vertical reciprocating motion.

The motive is a kind of fitness equipment, which can provide vertical reciprocating movement up and down. The user can perform exercises like skipping rope while standing on the motive.

The conventional motive part adopts the design of belt pulley and connecting rod. For example, the reciprocating vibration exercise device of Republic of China Patent Publication No. I660762, the vibration fitness machine No. I664004, and the vibration fitness training device No. I302469 are all belt pulleys and connecting rods. Design, but the elasticity of the belt will cause relative sliding between the belt and the pulley (also called elastic sliding). Elastic sliding will cause power loss and poor transmission efficiency, and make the belt easy to aging and slack.

Furthermore, the conventional motive may shake slightly from side to side. As shown in the first figure, when the conventional motive is driven by the connecting rod 10 to move the cover 20 up and down, the fulcrum of the connecting rod 10 is fixed at On the base 30, therefore, the connecting rod 10 will link the cover 20 in an arc motion, so that the cover 20 does not completely reciprocate up and down in a vertical direction, but slightly shakes left and right. This kind of shaking is easy to cause the user to dizzy slightly, but under long-term use, it is also easy to have a negative impact on the body, such as a burden on the knee joints, especially the elderly or people with knee joint problems or knee joint injuries People.

Furthermore, such as the vibrating machine of the Republic of China Patent Publication No. I492773, the abstract of the case mentioned that there is an angle between the second link and the first link, and the included angle is used to reduce the horizontal deviation during arc motion.
