Besides, interposed frames 15 fitted to the upper ends of coil springs 11 are provided, the spherical pressers 4 are protruded from the guide cylinders 3 at the main body 2 while overlaying the interposed frames 15, and the main body 2 and a mount base 1 are coupled by engaging lock pawls 9 on the mount base 1 into recessed parts 17 recessed on the inner peripheral surface of the main body 2. Then, screws 18 are put into central holes 19 opened at the center of the main body 2 and the screw 18 is screwed into a female screw pipe 20 projected at the center of the mount base 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a press-type massage device which is widely sold not only in Japan but also around the world under the trade name of Nakayama type healing device.

[0002]

SUMMARY OF THE INVENTION An object of the present invention is to improve the structure in which each part is bonded and fixed by using an adhesive like a conventional type of anoma, and to assemble robustly without using any adhesive. It is an object of the present invention to provide a possible press type bellows.

[0003]

The means of the present invention are as follows. A base plate molded using a synthetic resin mold,
A main body also serving as a cover of the same material to be put on it, a spherical pressing element protruding from a plurality of guide cylinders protruding from the main body,
In a pressing type annealer composed of a base plate and a coil spring interposed between a spherical pressing element, an upright engaging piece in which a peripheral cut portion of a main body is engaged around the base plate is formed around the base plate. And a plurality of sets of notches are formed at predetermined intervals in the engaging pieces to derive a locking claw between the notches, and to a portion of the base plate surrounded by the engaging pieces. A plurality of circular projections that receive the lower end of the guide cylinder and a plurality of guide annular portions into which the coil springs are fitted are provided concentrically and integrally, and a reinforcing edge that receives the pressure of the coil springs is provided at the lower end of the guide annular portions. And an intermediate piece that fits on the upper end of the coil spring fitted on the guide ring and covers the spherical presser, and is provided on the inner peripheral surface of the main body. An internal thread that locks and connects the main body and the base board with a locking claw on the base board, and screws a screw inserted into the center hole of the main body The pressing-type massage machine erected on the base surface plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a base plate, and 2 denotes a main body that also serves as a cover, both of which are molded using a synthetic resin mold. On the surface of the main body 2, four guide cylinders 3 are integrally protruded,
The spherical pressing element 4 is made to protrude from the guide cylinder 3. An upright engagement piece 6 with which the peripheral step portion 5 of the main body 2 engages around the base plate 1 is integrally protruded over the entire circumference, and the upright engagement piece 6 has a pair of cutouts 7, 7 'at required intervals. A plurality of sets are formed, and the locking claws 9 are derived between the notches 7, 4 'of each set. A circular ridge 10 for receiving the lower end of the guide cylinder 3 and a guide ring portion 14 in which a coil spring 11 is fitted are provided integrally and concentrically in the interior surrounded by the upright engagement pieces 6. A reinforcing edge 12 for receiving the pressure of the coil spring 11 and a stopper 13 for the coil spring 11 project radially from the lower end. Also, an intermediate piece 15 fitted on the upper end of the coil spring 11 fitted on the guide ring portion 14 is provided, and the spherical pressing element 4 is put on the intermediate piece 15 so as to protrude from the guide cylinder 3 of the main body 2. Recessed part 1 recessed on the inner peripheral surface
The main body 2 and the base board 1 are connected by engaging the locking claws 9 of the base board 1 with the base 7, and a center hole 19 into which a screw 18 enters is formed at the center of the main body 2, and At the center, a thread tube 20 for screwing the screw 18 inserted into the center hole 19 is provided in a protruding manner.

[0005]

According to the present invention, the following effects can be obtained.
Practical value as a press type massage device is improved.

[0006] Since the base plate and the main body are connected to each other by the locking action of the claws without using any adhesive having a strong odor, it is extremely advantageous in terms of work.

All the structures can be securely fixed with one screw at the center.

Since the lower end of the coil spring is received by the reinforcing edge having the radial stopper 13, even if there is a slight deviation, the coil spring is accurately received, falls off from the reinforcing edge, and does not fall.

[0009] Since the coil spring, the intermediate piece and the spherical pressing element are all assembled simply by mounting them on the base plate, covering the main body and fixing them with claws, the assembling work is performed quickly.
