Description

[Detailed Description of the Invention] The present invention relates to a roller pressure adjustment structure for a roller pine surge device, and more specifically, it includes a roller movable section provided in the longitudinal direction of the center of the base, and a roller movable section that is rotatably disposed in the roller movable section. The present invention relates to a roller pressure adjustment structure for a roller pine surge device, which has a roller provided therein, and performs a pine surge action by reciprocating or circulating a roller movable portion.

In conventional roller pine surge devices, the height of the base is constant, and the roller pressure that drives the roller movable part in reciprocating or cyclical motion may be too strong or too weak depending on the physique, weight, etc. of the person receiving the pine surge. In many cases, it is difficult to obtain the optimal roller pressure.
Further, adjusting the position of the roller in the roller movable section up and down requires a complicated mechanism and is not economical.

The purpose of this invention is to be able to easily and quickly adjust the roller pressure according to the physique, weight, preference, etc. of the person undergoing pine surgery without having to adjust the position of the roller vertically relative to the base. The present invention provides a roller pressure adjustment structure for a roller pine surge device, which will become clear from the detailed description below with reference to the drawings.

FIGS. 1 and 2 each schematically show an embodiment of a roller pressure adjustment structure of a roller pine surge device according to the present invention, and in this embodiment, it is shown as a bed type roller pine surge device 1. However, it can also be applied to a chair-type roller pine surge device.

This roller pine surge device 1 has a bed-type base 2, a head support portion 3 is formed at one end in the longitudinal direction of the base 2, and a roller movable portion is formed in the longitudinal direction of the central portion of the base 2. 4 is formed, and a roller 5 is disposed in this roller movable portion 4 so as to be freely rollable. The roller 5 rotates around a rotating shaft 6, and the rotating shaft 6 is configured to reciprocate or circulate in the longitudinal direction of the roller movable section 4.Detailed explanation of the drive mechanism of the roller 5 is omitted.

A pair of air bags 8 are provided on both sides of the roller movable section 4.
An air chamber 9 is formed. This air bag 8
is an air pipe 10 formed of synthetic resin or rubber material to maintain airtightness and connected to the air bag 8.
Air is supplied from the air pump 11 via the air pump 11. Note that this air pump 11 can be of an electric type as well as a manual type.

If the air chamber 9 is inflated by the amount of air supplied to the air chamber 9, and the air bag 8 is formed so that it can expand only upwards as shown in FIG. The height can be adjusted. Moreover, the air bag 8 can also be constructed so as to be able to expand toward the roller movable portion 4 side in the left-right direction.

By forming the head support portion 3 so that it can be moved and adjusted in the vertical direction, it is also possible to vary the pine surge effect. Furthermore, by disposing appropriate cushion pads on the upper parts of the roller movable part 4 and the air bags 8 and covering them with skin, the cushioning properties and feel of the base 2 and the rollers 5 can be improved.

The above is the configuration of one embodiment of the roller pressure adjustment structure of the roller pine surge device according to the present invention.
As shown by the solid line in the figure, if the roller pine surge device 1 is used with the roller 5 protruding a large amount, the upper end of the roller 5 will come into sufficient contact with the human body, and sufficient weight will be applied to the human body. When the contact feeling is strong, that is, when the roller pressure is high, the pine surge effect can be applied. From this state, the air pump 11 is activated to supply air to the air chamber 9, and the second
As shown by the two-dot chain line in the figure, when the air bag 8 is inflated, the relative height of the roller 5 is lowered, and since the human body is held by the air bag 8, the upper end of the roller 5 lightly hits the human body. It is possible to receive the pine surge effect even when the roller pressure is low. Although not shown, if the air is gradually extracted from the air chamber 9,
Roller pressure can be gradually increased. Furthermore, by adjusting the vertical position of the head holder 3, a roller pine surge effect can be obtained at the neck.

According to the present invention, the physique of the person undergoing pine surge can be improved with a simple configuration that only adjusts the air in the air chamber without adjusting the position of the roller vertically relative to the base.
It is possible to obtain an economical roller pressure adjustment structure for a roller pine surge device that can extremely easily adjust the roller pressure according to body weight, preference, etc.

As shown in Fig. 3, a plurality of pairs of air chambers 9 are formed in a divided state along the longitudinal direction of the roller movable portion 4, so that each air chamber 9 can adjust air independently. At this time, if an adjustment section 13 is formed in which the exhaust valves of each air chamber 9 are concentrated in one place, the air can be adjusted extremely easily.
