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.

FIG. 1 and FIG. 2 each schematically show an embodiment of the roller pressure adjustment structure of a roller gusset surge device according to the present invention, and this embodiment is shown as a bed-type roller gusset surge device. 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 at the center 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 is configured so that the rotating shaft 6 can 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 body receiving parts 8 are formed along both sides of the roller movable part 4 on the base 2. This body receiving part 8 is made up of a receiving part frame 9 made of synthetic resin or the like and having a substantially L-shaped cross section as shown in FIG. 10 and an outer cover 11 that covers the outside of the cushion pad 10, and a guide piece 1 extending in a direction perpendicular to the longitudinal direction of the body receiving part 8 is provided at the lower part of the receiving part frame 9.
2 is formed protrudingly. This guide piece 12 fits into a guide groove 13 formed on the upper part of the base 2,
The body receiving part 8 is formed to be slidable in a direction perpendicular to the longitudinal direction of the roller movable part 4. Although not shown, the body receiving portion 8 is configured to be locked at an appropriate position on the base 2.

As shown in FIG. 3B, if the cushion pad 10' of the body receiving part 8 is formed so as to be inclined diagonally upward as it goes outward, the body receiving part 8 is provided with a pair of body receiving parts 8 on both sides. It is possible to hold the body securely and with a good sense of stability.

The above is the structure of one embodiment of the roller pressure adjustment structure of the roller pine surge device according to the present invention. 4, when the body lies on the upper part of the roller pine surge device 1, the body is held by the body receiving part 8 and the body is not pressed sufficiently against the roller 5, and the upper end of the roller 5 gives a light feeling of contact to the body, and can receive the pine surge effect even when the roller pressure is low. Moreover, as shown by the chain line in FIG. 2, if the body receiving part 8 is used in a state where it is gradually moved away from the roller movable part 4, the distance between the pair of body receiving parts 8, 8 will gradually increase.
As the body part supported by the body receiving part 8 gradually decreases and sufficient weight is applied to the roller 5, the reaction of the body part causes a strong feeling of contact with the roller 5.
In other words, the pine surge effect can be applied in a state where the roller pressure is high.

According to the present invention, there is no need to vertically adjust the roller and the roller movable part with respect to the base, and the body receiving part can be adjusted according to the physique, weight, preference, etc. of the person receiving the pine surge with a simple configuration. Thus, it is possible to obtain a roller pressure adjustment structure for a roller pine surge device which is excellent in economic efficiency and can adjust the roller pressure extremely easily.

The embodiment described above merely shows one embodiment of the present invention, and the adjustment of the body receiving portion 8 is limited to moving the body receiving portion 8 in a direction perpendicular to the longitudinal direction of the roller movable portion 4. Instead, for example, as shown in FIG. 4, the body receiving part 8 may be mounted so as to be tiltable about a pivot shaft 15 extending parallel to the longitudinal direction of the roller movable part 4. Any device may be used as long as it can adjust and maintain the position of the body receiving pine surge with respect to the roller movable part 4 and roller 5 fixedly disposed in the vertical direction, and adjust the roller pressure, as shown in FIG. as,
The body receiving part 8 is divided into a plurality of parts along the longitudinal direction of the roller movable part 4, and each body receiving part 8 is independently moved and adjusted in the width direction, so that different roller pressures are obtained in each part of the body receiving part 8. You can also do this.
