Description

[Detailed description of the invention] (a) Purpose of the invention (industrial field of application) This invention relates to a bed-type pine surgery machine whose purpose is to perform pine surgery in a supine position.

(Conventional Known Technology) This type of conventional pine surge machine uses a plurality of massage balls that are driven back and forth by an electric motor via a chain or belt to pine surge the back of the human body. Despite the fact that the most important areas are the nape of the neck and lower back, no bed-type pine surge machine has been developed that focuses on these areas.

(Problems to be Solved by the Present Invention) In order to improve the above-mentioned drawbacks, the present invention provides a frame body that seesaws at the bottom of the bed, and an actuating device equipped with massage balls at both ends of the frame body. By connecting one side of the frame body and the elevating body, the actuating device on the side requiring pine surgery is raised via the elevating body, thereby making it possible to perform pine surgery on the nape of the neck or lower back.

(b) Structure of the present invention (means for solving the problem) A machine frame 2 is installed in the lower part of the bed main body 1, a support shaft 3 is installed in the upper part of one side of the machine frame, and this is attached to the support shaft. A frame body 4 that seesaws as a fulcrum is attached. Gearboxes a and a' containing worm gears are respectively attached to the lower surfaces of both ends of the swinging frame, the upper ends of each worm shaft 5 protrude upward and a pulley 6 is fixed, and electric motors M and A' are installed on one side of each gearbox.
Belt 8 between the motive wheels 7, 7' of M' and the above pulley
are respectively constructed, both ends of a driven shaft 10 to which a worm gear 9 is fixed are used as eccentric shafts, and base parts 12 and 12' to which kneading balls 11 and 11' are attached are rotatably attached to the eccentric shaft parts, The base is swingably supported by a support rod 16 provided with ball heads 14 and 15 at both ends of a support portion 13 provided at the lower stage of the frame, but rotation is prevented. One side of the above frame (rear side in the drawing)
A rotating screw shaft 17 is set upright on the side, and an elevating body 18 that is threadedly engaged with the shaft to move up and down is provided, and the elevating body and the frame are connected to each other so that the ends of the frame are moved up and down as the elevating body moves up and down. Pulley 1 is fixed to the rotating screw shaft so that it moves up and down.
9 and a driving vehicle 20 of an electric motor M''.

(Function) Since the present invention has the above configuration, the electric motor
M'' to rotate the screw shaft 17 and lift the elevating body 18.
When the frame body 4 is raised, the inner end of the frame 4 rises using the support shaft 3 as a fulcrum, so that the inner kneading balls 11' rise. Therefore, when the electric motor M' is rotated to rotate the worm shaft 5 via the pulley 6 and the belt 8, and the worm gear 9 that meshes with the worm shaft 5 is rotated, the driven shaft 10 to which the gear is fixed forms an eccentric shaft at both ends. Because of this, the base 11' swings and the massage balls 1
1' will perform pine surgery on the lumbar surface of the human body.

Next, when performing a massage on the nape of the neck, the electric motor M'' is rotated in the opposite direction and the lifting body 18 is lowered, so that the frame body 4 uses the support shaft 3 as a fulcrum and the massage balls 11 on the front side rise. The nape of the neck can be massaged in the same manner as described above.Although not shown, each electric motor is rotated by a switch operation.

(Example) To describe an example regarding the drawing, the bed main body 1
A machine frame 2 for mounting is installed in the lower part of the frame, a support shaft 3 is installed in the upper part of one side of the frame, and the center part of the frame body 4 is attached to the support shaft so as to be able to see-saw freely. Gearboxes a and a' each containing a worm gear are attached to both lower surfaces of the frame. The upper end of each worm shaft 5 is projected upward and a pulley 6 is fixed thereto, and a belt 8 is installed over a driving wheel 7 of an electric motor M, M' installed on one side of each gear box. A driven shaft 10 to which a worm gear 9 that meshes with the worm is fixed has an eccentric shaft at both ends, and a base 12, 12' to which kneading balls 11, 11' are attached is rotatably attached to the eccentric shaft, The base includes a support rod 16 provided with ball heads 14 and 15 at both ends of a support section 13 provided at the lower stage of the frame.
It is supported so that it can swing freely, but rotation is prevented. 1
Reference numeral 7 denotes a screw shaft installed near the rear side of the frame, and an elevating body 18 that is screwed onto the shaft and can be raised and lowered is provided, and the elevating body and the frame are connected 19 to allow the elevating body to be raised and lowered. Accordingly, the frame body can freely see-saw around the support shaft 3.

Motor vehicle 20 of electric motor M″ that rotates the above screw shaft
A belt 21 is installed between the pulley 19 and the pulley 19 fixed to the screw shaft.

In the drawing, reference numeral 22 indicates an exposure hole provided in the main body of the bed, from which the massage balls are partially exposed for operation.

23 is the leg of the bed.

(c) Effect As mentioned above, since the actuating device is attached to both sides of the frame body 4, the front side can be raised using the support shaft 3 as a fulcrum, and the nape of the neck can be massaged with the massaging balls 11, or the back side can be raised. You can freely set whether you want to massage your lower back with the massage ball 11'. Unlike conventional products, it can concentrate on the lower back or neck while lying on your back, so the pine surge effect is excellent. Of course, if the frame is kept horizontal, it can be used as a normal bed.
