この発明はマツサージ機に用いられるもみ輪に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kneading wheel used in a pine surge machine.
従来、第１図ないし第４図に示すマツサージ機

に腰掛けた人の背中を押圧してマツサージする。 Conventionally, a pine surge machine shown in FIGS. 1 to 4 has been used. In the figure, reference numeral 1 indicates the main body of the pine-surge machine serving as a chair, and a pair of kneading wheels 3 are attached to a support shaft 2 within the cover of the backrest 1a.
is located. The kneading wheel 3 is raised and lowered by a drive device (not shown) while rotating within the backrest portion 1a within the range of a stroke l,
Press down on the back of the person sitting on the chair to perform a pine surge.

め、疲労破壊の原因となる。 The kneading ring 3 includes a contact ring 4 made of rubber, an annular frame 5 provided concentrically inside the ring, and a large number of rings that integrally protrude from the annular frame 5 in an inclined direction and whose tips are embedded in the contact ring 4. It consists of an elastic support piece 6. However, with this kneading wheel 3, the kneading force and the concave displacement of the contact ring 4 increase almost proportionally, so that the kneading force is weak even if the kneading wheel 3 is greatly deformed. However, if the rigidity of the elastic support piece 6 is increased, the kneading force increases, but the contact against the back is hard and causes pain, resulting in a poor feeling of use. Further, if the rigidity of the elastic support piece 6 is weakened, a large stress is generated near the base of the elastic support piece 6, which may cause fatigue failure.
したがつて、この発明の目的は、弱いもみ力と
強いもみ力とに分けて使用することができて、も

み輪を提供することである。 Therefore, the object of this invention is to be able to use a weak kneading force and a strong kneading force separately, to obtain both increased kneading effect and soft contact, and to reduce fatigue fracture. The aim is to provide a massaging wheel that can be used for massaging.

れている。 An embodiment of this invention is shown in FIGS. 5 to 10. In the figure, 7 is a contact ring made of rubber and has a circular cross-sectional shape. A synthetic resin annular frame 8 is provided concentrically inside the contact ring 7, and has elastic support pieces 9 integrally provided on the outer periphery at regular intervals in the circumferential direction. Each elastic support piece 9 is inclined in the circumferential direction with respect to the radial direction of the annular frame 8, and a contact ring embedding piece 11 provided in a T-shape at the tip is embedded in the contact ring 7. Near both ends of the elastic support piece 9,
It is slightly curved so as to approach the radial direction of the annular frame 8. 10 is a hardness adjustment adapter, which includes a disk-shaped adapter body 10a and this adapter body 1.
It consists of a large number of protrusions 10b that protrude laterally at regular intervals in the circumferential direction on the outer peripheral edge of Oa. Projection 10b
The hardness adjustment adapter 10 is detachably attached to the annular frame 8 by fitting the protrusion 10b onto the annular frame 8.
The protrusion 10b has a semicircular cross-sectional shape, and the protrusion height from the annular frame 8 is set to a height at which the elastic support piece 9 comes into contact with the elastic support piece 9 in a state of being bent to some extent.
このように構成したため、接触リング７を背中
で押えたときに、しばらくは柔らかく弾性支持片
９が撓み、弾性支持片９が硬さ調整アダプタ１０
の突部１０ｂに当たると急に荷重が大きくなる。
すなわち、荷重と変形の特性は、従来では第１０

で示すようになる。そのため、もみごたえ感が高
まり、効果的なマツサージが行なえ、しかも背中
１３の当たりが柔らかになる。また、弾性支持片
９を大きく撓ませなくても済むことから、弾性支
持片９の疲労破壊が緩和される。 Because of this configuration, when the contact ring 7 is pressed with the back, the elastic support piece 9 is soft for a while and bends, and the elastic support piece 9 becomes the hardness adjustment adapter 10.
When it hits the protrusion 10b, the load suddenly increases.
In other words, the characteristics of load and deformation are conventionally
What was supposed to be indicated by the broken line a in the figure is now the solid line b.
It will be shown as follows. Therefore, the feeling of massaging increases, effective pine surge can be performed, and the back 13 feels softer. Further, since the elastic support piece 9 does not need to be bent significantly, fatigue failure of the elastic support piece 9 is alleviated.
なお、硬さ調整アダプタ１０に突部１０ｂの高
さの異なるものを種々準備しておけば、硬さ調整
アダプタ１０を取換えることにより、第１０図に

曲線ａとｂの傾斜が低荷重の場合でも変わつてい
るのは、弾性支持片９の数を従来のものに比べて
少なくしたためであり、同じ傾斜になるようにし
てもよい。 If you prepare various hardness adjustment adapters 10 with different heights of protrusions 10b, you can change the hardness adjustment adapter 10 as shown by chain lines b' and b'' in FIG. , the load deformation characteristics can be changed, and the load deformation characteristics can be selected according to the user's preference.In addition, in Fig. 10,
The reason why the slopes of curves a and b change even when the load is low is because the number of elastic support pieces 9 is reduced compared to the conventional one, and the slopes may be the same.

る。 As described above, the massaging ring of the present invention includes a flexible contact ring, an annular frame provided concentrically inside the contact ring, and an appropriate interval in the circumferential direction between the annular frame and the contact ring. This is because the contact ring is provided with elastic support pieces that are provided at intervals to elastically support the contact ring, and a deflection prevention portion that prevents the elastic support pieces from deflecting when the elastic support pieces are bent to a certain extent. When you press the contact ring, it will be soft for a while, but if you press it too hard, the deformation resistance will suddenly increase. As a result, the feeling of massage increases, effective pine massage can be performed, and the back feels softer. moreover,
This has the effect of improving the durability of the elastic support piece.
