Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to an improvement of a pine surge device, and particularly provides a pine surge device with excellent acupressure effects.

<Prior Art> Various types of pine surge devices have been known for relieving back stiffness.

For example, one is known in which a long pressure roller made of an elastic material is rotatably held in the middle of a support shaft. This is used by gripping both ends of the support shaft, which functions as a gripping part, and rotating the pressing roller while pressing it against the back. However, the above-mentioned pine massage device, which rotates a pressure roller while pressing it against the back, has not been able to provide a sufficient acupressure effect because it is difficult to adjust the pressure depending on the affected area.

<Purpose of the invention> The present invention provides a pine surge device with excellent acupressure effect.In particular, the pressing force of the pressing protrusion attached to the outer circumferential surface of the disc body can be adjusted depending on the strength of the stiffness. This is what I did.

<Configuration of the invention> In order to achieve the above object, the pine surge device of the invention has the following configuration. In other words, a pair of disc bodies are rotatably held at a predetermined interval in the middle of a support shaft, and both ends of the support shaft serve as gripping parts, and spring pressure is constantly applied to the outer peripheral surface of each disc body. This is characterized in that a plurality of pressing protrusions are attached at predetermined intervals and are urged to protrude in the outer circumferential direction.

<Embodiment> Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a pine surge device main body, and this pine surge device holds a pair of disk bodies 3, 3 rotatably at a predetermined interval in the middle part of a support shaft 2, and
Both end sides of the support shaft 2 serve as gripping parts 4, 4, and on the outer peripheral surface of each of the disc bodies 3, 3, there are predetermined pressing protrusions 5, which are always urged to protrude in the outer peripheral direction by spring pressure. It is constructed by attaching multiple pieces at intervals.

The pair of disk bodies 3, 3 are connected to a support shaft 2 made of metal.
It is held at a predetermined interval by being arranged via a synthetic resin interval adjustment ring 6 held in the holder, and the outer surface of the support shaft 2, which corresponds to the grip part 4, is firmly attached to both ends of the support shaft 2. Further, it is rotatably held on the support shaft 2 by being held by the inner end surfaces of the rubber covers 7, 7, which are removably fitted, via synthetic resin sliding rings 8, 8. Incidentally, since the disk body 3 shown in this embodiment is formed of a metal material, the contact surface 3a of the disk body 3 with the support shaft 2
is made of synthetic resin to ensure smooth rotation.

A plurality of pressing protrusions 5 attached to the outer peripheral surface of each disc body 3 are formed in a cylindrical shape, and the protruding surface 5a located on the outside is formed in a loose rounded shape and is located on the inside. The base surface has a recess 5b into which one end of a spring to be described later is inserted;
A screw through hole 5c is formed passing through the ring center of the cylinder, and a locking step portion 5d is formed on the inner wall surface of the screw through hole 5c. The pressing protrusion 5 is slidably inserted into a loose insertion hole 9 formed at a predetermined interval on the outer peripheral surface of the disc body 3, and is inserted between the recess 5b of the pressing protrusion 5 and the bottom of the loose insertion hole 9. The locking step 5d formed in the screw through hole 5c of the pressing projection 5 due to the spring pressure of the installed spring 10
An adjustment screw 11 passes through the screw through hole 5c and is screwed onto a female screw 9a formed in the loose insertion hole 9.
It is urged to protrude in the outer circumferential direction to a position where it is locked with the head 11a. Note that 12 is a cap made of an elastic material such as rubber, which is attached to the protrusion of the pressing projection 5.

When using the present invention, the protruding state of the pressing protrusion 5 is adjusted in advance with the adjusting screw 11, and then,
The gripping parts 4, 4 are gripped with both hands, and the pressing protrusions 5 are sequentially pressed to predetermined positions on the back while rotating the disc bodies 3, 3. At this time, the pressing protrusion 5 is biased with spring pressure in the outer circumferential direction by the spring 10, so that the pressing protrusion 5 has a severe stiffness, as shown in the lower right of FIG. When pressing a hard affected area, the pressing protrusion 5 is configured to be slightly depressed against the spring pressure of the spring 10, and the protrusion state of the pressing protrusion is adjusted depending on the affected area.

The pair of disk bodies 3, 3 are set at a predetermined distance L by a distance adjustment ring 6, but by changing the width of the distance adjustment ring 6 or increasing or decreasing the number of adjustment rings, the distance between each of the disk bodies 3, 3 can be adjusted. Of course, the interval L between 3 and 3 can be set to any width. In addition, in the embodiment, the position of the pressing protrusions 5 attached to each disc body 3, 3 is aligned on the left and right when used.
Since each disc body 3, 3 is formed separately,
Of course, by slightly rotating one disc body 3, the position of one protrusion may be slightly shifted from the position of the other protrusion, and the pressure may be applied in a state where each protrusion position is shifted.

<Effects of the invention> The pine surge device according to the invention rotatably holds a pair of disc bodies at a predetermined interval in the middle part of a support shaft, and both ends of the support shaft serve as gripping parts. The outer circumferential surface of each disc body is constructed by attaching a plurality of pressing protrusions at predetermined intervals, which are constantly urged to protrude in the outer circumferential direction by spring pressure. When pressing, the pressing protrusion is slightly depressed against the spring pressure of the spring, and the protruding state of the pressing protrusion is automatically adjusted according to the stiffness of the affected area.

Therefore, the present invention can provide a pine surger that has an excellent acupressure effect and can provide a pressing force that corresponds to the state of stiffness in the affected area.
