Abstract

PURPOSE:To enable a massage machine to be used in a state as relaxing as possible without giving an unpleasant feeling to a user's back by setting a massaging body, which is equipped with two or more rotatable rollers, movable in longitudinal direction of a base stand of bed. CONSTITUTION:A massaging body 6, which is equipped with two or more rotatable rollers 8 around a supporting shaft 7, is screwed with and supported by two threaded bar shafts 5 at the both end parts, so that it is made possible to move in longitudinal direction of a flat base stand 1 of a bed. To operate this massage machine, it is sufficient only to drive a motor 2, which makes worms 4 turn around through couplings 21 for the driving motor 2 and couplings 31 for driving shafts and makes both threaded bar shafts 6, which mesh with respective worms 4, turn around. There are no fears of either giving an unpleasant feeling caused by a threaded shaft situated at near center of a user's back or bringing about a breakdown caused by cutting of a wire or a steel belt.

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a bed-type pine surgery machine capable of performing whole-body pine surgery in a supine state, and in particular, to a bed-type pine surgery machine that reliably supports a rotatable roller for pine surgery. This invention relates to a drive mechanism for a bed-type pine surgery machine which can move the machine forward and backward, and perform pine surgery without causing discomfort to the user during use.

(Prior art and its problems) A bed-type pine surge machine is generally equipped with a rotatable pine surge roller that is driven and driven by a drive device inside the bed base, and guide rails provided on both sides of the bed base. The above-mentioned rotatable roller is configured to move and run on the upper part of the body, and when the user lies down on this head-type pine surge machine, the pine surge roller slides and rotates on the back side of the human body, applying acupressure to the back of the human body. This allows for dynamic pine surge.

By the way, in the drive mechanism of this kind of conventional bed-type pine surge machine, a screw shaft that is interlocked with the drive motor via a belt is disposed approximately in the width direction of the bed base, and a screw shaft for pine surge is attached to the screw shaft. A rotary roller is screwed together to move the rotatable roller in the longitudinal direction of the bed base, and a wire or steel belt is connected to a drive motor in the forward and reverse directions.

In this case, the rotatable rollers for pine surge are pulled by wires or steel belts, so if too much load is applied to the rotatable rollers, these wires or steel belts may break. ,
There was also the problem that this caused the device to become unusable.

(Object of the Invention) The present invention has been made in view of the above-mentioned problems, and it is possible to avoid causing discomfort to the back of the user's body when performing pine surgery while lying down on a bed base. The purpose of the present invention is to provide a drive mechanism for a bed-type pine surge machine that can be used in a relaxed state and that does not cause the wire or steel belt to break during use, making it unusable and causing spinal injuries. It was created as a.

(Structure of the Invention) That is, the drive mechanism of the bed-type pine surge machine of the present invention includes a drive motor mounted on one end of a flat bed base in a longitudinal direction perpendicular thereto, and both drive shaft ends of the drive motor. A pair of rod-shaped screw shafts are arranged along both sides of the bed base in the longitudinal direction and have one end engaged with each of the worms so as to be interlocked with each other. , both sides of the bed are threaded onto both rod-shaped screw shafts to hold the structure, and a pine surge body having a plurality of rotatable rollers mounted on the support shaft is configured to be movable in the longitudinal direction of the bed base. It is something to do.

(Action of the invention) Therefore, the drive mechanism of the bed type pine surge machine of the present invention is as follows:
The configuration described above brings about the following effects.

That is, the drive mechanism of the bed-type pine surge machine of the present invention includes a pair of bar-shaped screw shafts arranged along both longitudinal sides of the bed base via worms at both drive shaft ends of the drive motor, respectively. The rod-shaped screw shaft allows the pine surge body to move, so when performing pine surge while lying down on a flat bed base, the pine surge can be performed while supporting the back of the user's body as the pine surge body passes through. By burying the back part in the lower part, it is possible to perform pine surgery safely and comfortably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drive mechanism of the bed-type pine surge machine of the present invention will be described in detail below based on an embodiment shown in the drawings.

(Embodiment) FIG. 1 shows an embodiment of the drive mechanism of the bed type pine surgery machine of the present invention. A mounted drive motor 2, a worm 4 connected to both ends of the drive shaft 3 of the drive motor 2 and rotated in synchronism, and the bed base 1.
A pair of rod-shaped screw shafts 5 are disposed along both longitudinal sides of the worms 4 and have one end interlocked with each of the worms 4. Both sides of the pine serge body 6 are screwed together and held so that the pine surge body 6 can be moved in the longitudinal direction of the flat bed base 1.

That is, as shown in FIG.
The bed is made up of a cloth 12 that is wrapped around the opening surface of the bed so as to cover the entire upper surface thereof, and the user can lie down on the bed base 1 in a relaxed state as much as possible. It is.

As shown in FIG. 2, the drive motor 2 is mounted perpendicularly to one end of the flat bed base 1 in the longitudinal direction, and its motor shafts (not shown) each protrude on an extension line. Fixed to set.

Incidentally, a coupling 21 for the motor shaft and a coupling 31 for the drive shaft are provided between the motor shaft and the drive shaft 3 disposed on an extension line of the stiffness, and both couplings 2
1.31, the two are configured to be linked.

Further, worms 4 are attached to the ends of both moving shafts 3 of the drive motor 2, and are rotated in synchronization with the rotation of the drive motor 2, and the rotation is transmitted to each of the rod-like screws! 1iII
15, and each rod-shaped screw IPI15 is rotated in synchronization.

As shown in the figure, the bar-shaped screw shaft 5 is rotatably held at one end by a screw holding case 51 and rotatably held at the other end by a holding cylinder 52, so that no additional load is applied to the screw shaft 5. The deflection of the screw shaft 5 caused by this is prevented as much as possible.

Therefore, both rod-like screws @5 of the drive mechanism of the bed-type pine surge machine configured as described above have screws on both sides of the pine surge body 6, which has a plurality of rotatable rollers 8 mounted on the support @7. This allows the pine surge body 6 to be moved in the longitudinal direction of the flat bed base 1.

A limit switch 9 is provided at the end of the flat bed base 1, that is, at the end of the movement of the pine serge body 6, so that the pine surge body 6 can move repeatedly. When the ends of the body 6 come into contact with each other, the direction of rotation of the motor shaft of the drive motor 2 can be reversed, and the direction of movement of the pine surge body 6 can be reversed.

(Function of the Embodiment) The drive mechanism of the bed type pine surge machine of the present invention is constructed as shown in the above embodiment, so in order to use it, all that is required is to operate the drive motor 1. The worms 4 can be rotated through the motor shaft coupling 21 and the drive shaft coupling 31 of the drive motor 2, and each rod-shaped screw shaft 5 meshed with each worm 4 can be rotated. The pine surge body 6 provided with a plurality of rotatable rollers 8 can be repeatedly moved along the longitudinal direction of the flat bed base.

(Effects of the Invention) As described above, the drive mechanism of the bed type pine surge machine of the present invention is for moving the pine surge body in which a plurality of rotatable rollers are mounted on the support shaft in the longitudinal direction of the flat bed base. This mechanism rotates a pair of bar-shaped screw shafts arranged on both sides of a flat head base in synchronization by the operation of a drive motor.
Since the pine serge body is screwed and held on the screw shaft, unlike conventional bed bases, the screw is connected to the drive motor via a belt and is interlocked with the reverse rotation of the screw located approximately at the widthwise center of the bed base. When performing pine surgery by pulling a wire or steel belt while lying on a bed base, the spiral shaft located approximately in the middle of the user's body may cause discomfort, or the wire or steel belt may break during use. There is no need to worry about the pine serge body becoming unusable or causing a breakdown, and you can use it with confidence while being as relaxed as possible.Furthermore, the present invention uses a pair of rod-like screw shafts on both sides to hold the pine surge body. The pine serge body can maintain a stable state at all times, there is no need to provide a guide rod for holding the pine surge body as in the conventional method, and manufacturing costs can be reduced.

Therefore, the drive mechanism of the bed type pine surge machine of the present invention is as follows:
This is an epoch-making product that can eliminate the various problems that arise when driving conventional bed-type pine surge machines.
