Massage unit and chair-type massage machine having the unit

Abstract

The invention provides a massage unit of reduced weight and low cost which is adapted to grip and knead the affected part of the user with upper and lower therapeutic members. The massage unit comprises: a kneading shaft (30) rotatably supported on a chassis (21), two output shaft portions (32) provided on the kneading shaft and inclined in directions opposite to each other with respect to an axis of the kneading shaft, a pair of left and right pivotal levers (60) each rotatably fitted at a base end thereof around the output shaft portion and having a free end portion projecting toward the person to be treated, the pivotal levers being movable by the rotation of the kneading shaft axially of the shaft, a first therapeutic member (40) provided on a forward end of each of the pivotal levers, an auxiliary lever (70) pivoted to an inside portion of the pivotal lever, an angle limiting member (90) having one end connected to a base end portion of the auxiliary lever and the other end connected to the chassis for limiting the angle of pivotal movement of the auxiliary lever, a pivotal arm (80) pivoted to the pivotal lever and so supported as to be slidable relative to the auxiliary lever, and a second therapeutic member (50) provided on an end of the pivotal arm, the first therapeutic member and the second therapeutic member being movable toward and away from each other by rotating the kneading shaft.

Description

technical field [0001] The invention relates to a massage mechanism and a chair-type massage machine with the massage mechanism. The massage mechanism makes the first treatment finger and the second treatment finger approach and separate, so that the shoulder of the treated person can be kneaded. Background technique [0002] A seat-type massage machine having a massage mechanism for massaging the shoulders, back and waist of a person to be treated is known. [0003] In this seat-type massage machine, a massage mechanism (for example, referring to Patent Document 1). [0004] In the massage mechanism of Patent Document 1, a first treatment finger is arranged via a swing arm relative to a swing bar that swings up and down and left and right, and a second treatment finger is supported on the swing bar and is slidable relative to the swing arm. [0005] The two ends of the swing arm are connected to the chassis in a manner to limit the swing angle through spherical balls, and...

AI Technical Summary

Problems solved by technology

If a strong force is applied to the affected area (such as the shoulder), the pendulum will deflect and cause more damage

In order to reduce losses and obtain a massage feeling, it is necessary to have a strong structure for the swing rod and the swing arm that transmit force to the first treatment finger. However, if the above two are formed with a strong structure, it will inevitably lead to enlargement of the massage mechanism, Increase in weight and cost

[0009] In addition, because the power transmission path of the second treatment finger also passes through the swing arm like the first treatment finger, it will not transmit enough force to the second treatment finger. In addition, the force acting on the swing arm is very large, which will also cause Increase in size, weight and cost of massage mechanism
