Abstract

PURPOSE:To execute the massage action by inclined crumpling rings corresponding to each part of the body by controlling the rotation of a spiral shaft to change and regulate the space between the inclined crumpling rings. CONSTITUTION:When a driving motor is started, each roller 7 are rotated along a cylindrical orbit, and a pair of inclined crumpling rings 8 are also rotated to exhibit the massage effect by the roller and the crumpling massage effect by the inclined crumpling ring. In this case, when a spiral shaft 10 is positively or reversely rotated as the pair of inclined crumpling rings 8, 8 are partly spirally fitted to the respective opposite directional spiral parts 10A, 10B of the spiral shaft 10, the pair of inclined crumpling rings 8, 8 are horizontally moved in opposite directions, so that the space between the inclined crumpling rings 8, 8 can be regulated. Thus, in spite of a compact device, the contact position of the inclined crumpling rings can freely be regulated to perform wide crumpling action.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a pine surge device, specifically a group of multiple roller rollers that rotate freely while rotating along a cylindrical trajectory;
The present invention relates to a compact pine surgery device for general household use, which is equipped with a pair of inclined massage wheels that rotate at the central position, and the interval between the massage wheels can be freely adjusted.

(Problems to be Solved by the Invention) The above-mentioned conventional pine surge device cannot freely change the interval between the left and right rubbing wheels, so there is a problem in that the range of action of pine surge by the inclined rubbing wheels is specified. In addition, since the cylinder on the outer wall of the motor is used as the rotational drive shaft, the fit between the cylinder on the outer wall of the motor and the motor must be precisely fixed to prevent it from becoming an eccentric rotating body, otherwise vibration will occur and cause noise, so advanced machining is required. In addition to requiring precision and high production costs, rotating the motor body as a rotary drive shaft has problems such as a large moment of inertia of the rotating body and high power consumption.

The present invention has been made for the purpose of solving the disadvantages described in 1- in a composite pine surge device comprising a plurality of rollers and a pair of inclined rubbing wheels.

A single helical shaft extending across the center plate and having helical portions in opposite left and right directions on one half and the other half thereof is rotatably supported by the center plate and both side plates. A part of the inclined kneading wheels is screwed onto the spiral portions in opposite directions, and a control means for rotating the helical shaft in forward and reverse directions is installed at one end of the screw shaft. This allows the interval between the two to be adjusted. The control means for rotating the above-mentioned screw shaft in the forward or reverse direction is not particularly limited and can be achieved by using an adjustment knob, etc., but when it is performed by operating a switch using the rotation of the drive motor, the above-mentioned A pinion is placed at one end of the screw shaft, and a gear is fitted to the axis of the cylindrical body so that it can rotate freely, and the gear is engaged with the pinion, and at the same time, the gear is fixed or rotates freely. For example, an electromagnetic brake is provided, and when the device is in operation, the first stage of the iMi brake is activated by operating a switch to fix the gear rotating in the tree,
As a result, the gear which was rotating together with the cylindrical body is stopped, and the above-mentioned binion is transferred along the outer periphery of the gear, and the rotation of this binion rotates the screw shaft. If you press the reverse switch to reverse the motor, the screw shaft will reverse, allowing you to adjust the spacing between the rubbing wheels.

Also, 1. The maximum and minimum distance between the pair of inclined rubbing wheels by controlling the rotation of the screw shaft described above is preferably regulated by a proximity switch or a rimino 1 switch.

(Function) When the drive motor is started, each of the rollers rotates along a cylindrical locus, and the pair of inclined rubbing wheels also rotates, so that the rollers perform a pine surge effect and the inclined massage wheels perform a massaging effect.

The screw shaft allows adjustment of the interval between the left and right inclined massage wheels, and although it is a compact device, the contact position 1 of the inclined massage wheels can be freely adjusted to provide a wide range of massaging effects to the human body. carry out.
