A linkage mechanism for foot massager

Abstract

The invention relates to a linkage mechanism for a foot massager. The linkage mechanism comprises a first wheel disc, a second wheel disc, a crank-rocker mechanism, a massage stick and a first cam, the first wheel disc, the second wheel disc and the crank-rocker mechanism can rotate, the massage stick is used for massaging foot dorsum, the first cam rotates along with the second wheel disc to drive a first sole massage plate to move along a straight line, the second wheel disc and the first wheel disc are directly or indirectly linked each other in the rotating aspect, one end of a crank of the crank-rocker mechanism is fixedly connected with the first wheel disc, so that the crank circumferentially moves along with the first wheel disc, and one end of the massage stick is rotatably connected on a rocker of the crank-rocker mechanism, so that the other end of the rocker massages the foot dorsum backwards and forwards under driving of the rocker. A plurality of positions of the sole andthe foot dorsum can be comfortably and effectively massaged in a simple transmission manner, the massage stick not only can massage the foot dorsum, but body feet are suitably positioned, downward pressing action force is applied to the feet, and manual downward stepping force application or the complicated process of using a foot fixing device is omitted.

Description

technical field [0001] The invention relates to the field of physical therapy devices, in particular to a linkage mechanism for a foot massager. Background technique [0002] Due to historical reasons, the development of the rehabilitation industry in my country is later than that in developed countries. However, under the attention and promotion of the Chinese government and relevant departments, some achievements have been made by drawing on the development models and ideas of the rehabilitation industry of developed countries in the world. With the steady progress of economic development and the period of population transition, my country is facing problems such as high work pressure and population aging. The foot massager can effectively help people relax and exercise. [0003] At this stage, most of the foot massagers on the market only repeatedly massage the sole of the foot, because the instep is not massaged, and it is necessary to artificially apply downward force...

AI Technical Summary

Problems solved by technology

However, the foot rollers and instep rollers of this foot bath are not linked, and multiple driving sources are needed. Moreover, after the feet are put in place, the position of the instep rollers cannot move back and forth along the instep, and can only massage a small part of the instep area, massage effect is limited

In addition, since the rocker arm uses a spring to exert a downward force on the foot, after the foot is placed in place, the clamping force exerted by the foot changes little, and there is no time for the foot to relax during the massage

[0008] By studying the above five technical solutions, even if those skilled in the art combine them, they cannot obtain a satisfactory foot massager

Especially to make a foot massager with simple structure, few driving sources, massage soles and insteps at the same time, wide instep massage area, and compress and relax the feet during the massage process, the challenge is even greater
