Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a massage bed, more specifically, a massage ring provided on a massage member running along the longitudinal direction of the bed, which covers the entire back of the body of a person lying supine on the bed. This relates to a pine surge bed that performs a pressing pine surge operation.

Generally, in this type of pine surge bed, side rollers are used to support the body on the bed on both sides of the massaging rings in order to enhance the massaging effect of the massaging rings. I am running along it. However, conventionally, as shown in FIGS. 1 and 2, two pairs of four side rollers 5,
Because they are placed on both sides of the axis 6,
As shown in the figure, when massaging the area from the neck to the shoulders with the massage ring 4, one of the side rollers 5 hits the shoulder and lifts the shoulder, resulting in the massage ring 4 There was a problem in that the force was not effectively transmitted to the treatment area and a sufficient pine surge effect could not be obtained. Furthermore, when the side rollers 5 move together with the kneading ring 4 from the neck to the shoulders, the small diameter side rollers hit the shoulders before the large diameter kneading rings 4, causing pain in the shoulders.

The present invention has been made in view of the above points, and its main purpose is to allow the side rollers adopted to support the body on both sides of the kneading ring to support the body from the neck to the shoulders. The massage ring does not get in the way when performing pine surgery, and the massage ring can effectively apply pine surgery to this area, and when the massage ring is moved from the neck to the shoulder with the side rollers, it softly touches the shoulder and gives a gentle massage to the shoulder. To provide a pine surgery bed that does not cause pain.

The present invention will be described in detail below based on embodiments shown in the figures. As shown in FIG. 3, the massage bed according to the present invention includes a bed 1 whose upper surface is covered with a flexible cover sheet 2, and a pair of massage rings 4.
and a pair of side rollers 5 disposed on both sides of the kneading ring. The kneading ring 4 is mounted eccentrically on the rotating shaft 6, and the kneading ring 4 receives the rotational force around the rotating shaft 6 and performs an eccentric movement, thereby displacing the cover sheet 2. A massage operation is performed to press the body lying on its back from below through the cover sheet 2. The side rollers 5 are rollers that support the body on the bed 1 on both sides of the massage ring 4, and the rotation shaft 6 One end of the bed 1, where the head of the body is located along the longitudinal direction of the bed 1, is attached at a shifted position with its axial direction matching the width direction of the bed 1, and the massage ring 4 along the longitudinal direction of the bed 1. As shown in FIG. 4, the bed 1 is composed of a rectangular frame 12 having legs 10 and a wooden box 11 on the lower surface of both longitudinal ends, and a flexible cover sheet 2 stretched over it. A cushion material 13 is attached to both edges in the width direction, and a pillow 15 and a handle bar 16 are attached to one end in the longitudinal direction. Rack 8 is attached to the inner surface of the frame 12.
Rails 7 equipped with the following are arranged along the longitudinal direction, and the above-mentioned pine surge member 3 is installed between both rails 7. As shown in the figure, this massaging member 3 consists of a main block including a pair of massaging rings 4 and a pair of side rollers 5 having a smaller diameter than the massaging rings 4, and a shaft 18 parallel to the rotating shaft 6 of the massaging rings 4. A sub-roller 19 is rotatably mounted. It is composed of a sub-block, and both are integrally connected by a pair of connecting plates 20. The main block is equipped with a motor block 22 having a motor M and a gear box 23. Cylindrical bodies 24 are freely rotatably attached to both ends of the rotating shaft 6.
The guide rollers 25 attached to both ends of the rail 7
By rolling within the bed 1, the pine surge member 3 moves along the longitudinal direction of the bed 1. The rotating shaft 6 is
As shown in FIG. 5, it is hollow and has a drive shaft 30 mounted therein, and the aforementioned cylindrical body 24 is fixed to both ends of this drive shaft 30. Each cylindrical body 24 is formed with a pinion 26 that meshes with a rack 8 attached to the rail 7, so that when the drive shaft 30 is driven to rotate, the mechanism section runs along the rail 7.

The motor M in the motor block 22, which can freely rotate forward and reverse, and the rotating shaft 6 and the driving shaft 30 are connected by a gear group and a planetary part in the gear box 23, and the rotational force of the motor M is transmitted between the rotating shaft 6 and the driving shaft 30. 30, so that one is driven to rotate while the other remains stationary.

As shown in the figure, the massage ring 4 is composed of an eccentric inclined shaft part 31 fixed to the rotating shaft 6, and an outer ring 32 freely rotatable around the outer circumference of the eccentric inclined part 31. A steel ball 34 and a retainer 33 are arranged between the outer ring 32 and the eccentric inclined shaft portion 31. This pair of kneading rings 4 attached to the rotating shaft 6 at a predetermined interval rotate together with the rotating shaft 6, but both kneading rings 4 are eccentric by the same amount in the same direction and tilted symmetrically. Therefore, as the rotating shaft 6 rotates, the amount of protrusion of the massage ring 4 toward the cover sheet 2 side changes, and at the same time, the distance between the respective contact parts of both massage rings 4 with the cover sheet 2 changes. Thus, in addition to the pressing force from below by the massage ring 4, compressive and tensile forces to the left and right act on the body lying supine on the bed 1 via the cover sheet 2, thereby applying massage to the body. In addition, a permanent magnet (not shown) is attached to the outer surface of the eccentric inclined shaft portion 31 of the massaging ring 4 on the gearbox 23 side, and the gear,
A pair of reed switches (not shown) arranged on the sides of the gearbox 23 are made to respond. Here, one reed switch is sensitive to the permanent magnet when the amount of protrusion of the kneading ring 4 toward the cover sheet 2 side is small, and the other reed switch is sensitive when the amount of protrusion of the kneading ring 4 toward the cover sheet 2 side is large. As will be described later, the strength of the pressure applied to the back during the sari pine surge is adjusted.

On the other hand, as shown in FIG. 4, FIG. 7, and FIG. 8, the side rollers 5 are arranged at positions where the pillow 15 at one end of the bed 1 is shifted from the rotating shaft 6 of the massage ring 4, respectively. These are disposed on the outside and are freely rotatable on support shafts 9 that are parallel to the rotating shaft 6, and are used to support the body B on the bed 1 on both sides of the massage ring 4 through the cover sheet 2. While supporting it, when the pine surge member 3 travels, it advances together with the kneading ring 4 while rotating along the cover sheet 2.

Next, the operation of the present invention will be explained. When the driving force of the motor M is switched to the drive shaft 30 and the massage member 3 is moved along the longitudinal direction of the bed 1, the massaging ring 4 freely rotates its outer ring 32 and passes through the cover sheet 2 to the human body. While pressing both sides of the back side along the spine, the sub roller 19 presses the massage ring 4.
The massage is performed by pressing the back of the foot at regular intervals. The movement range and reversal position of this pine surge member 3 are controlled by a microcomputer, so that pine surge can be performed intensively at any desired location. Furthermore, if only the rotary shaft 6 is rotated without rotating the drive shaft 30, the massaging ring 4 rotates at a fixed location.
Since the kneading ring 4 is eccentric and inclined with respect to the rotating shaft 6, as it rotates, the amount of protrusion toward the cover sheet 2 side is large and the distance between the upper ends of both kneading rings 4 is small, and the cover sheet 2 A state in which the amount of lateral protrusion is small and the distance between the upper ends of both kneading rings 4 is large alternately occurs, and this is how the kneading massage is performed. Also, when performing the above-mentioned pine massage, the pressure applied to the back by the massage ring 4 changes as the rotational position of the massage ring 4 changes, so the strength can be adjusted. This is provided to detect the rotational position of the massage ring 4 for adjustment.

The side rollers 5 are used to adjust the strength of this rubbing pine surge and to perform the massaging pine surge more effectively, and when the amount of protrusion of the massaging ring 4 toward the cover sheet 2 side is large, the side rollers 5 However, when the amount of protrusion of the kneading ring 4 is small, both sides of the body are supported by the side rollers 5. Since the side rollers 5 move along with the kneading ring 4 and the auxiliary roller 19, when performing the pine surge, the side rollers 5 also move in contact with the body when doing this at a low speed, allowing a wide range of motion. It is possible to perform pine surgery on the body part and to give a soft feel to the pine massage.Furthermore, if only the massage rings 4 are used during massage pine surgery, the body will always be supported by two massage rings 4, so the body will be I am constantly in a state of tension, which hinders treatment, but the massaging ring 4
When the amount of protrusion becomes small, the body is also supported by the side rollers 5, so the tension is relieved while the body is supported by the side rollers 5 as well. In other words, the treatment is more effective because the patient is repeatedly brought into a state of being relieved of tension. In addition, as described above, the side rollers 5 are arranged at a position where the pillows 15 are shifted from the massaging ring 4 along the longitudinal direction of the bed 1, so as shown in FIGS. 7 and 8. When massaging the area from the neck to the shoulders using the massaging ring 4, the side rollers 5 support the cover sheet 2 at the parts that are separated from each other on both sides of the neck. The massage ring 4 does not interfere with the massage operation by the massage ring 4, and sufficient massage can be applied to this area. Also, when performing the above-mentioned rubbing pine surge by running the pine surge member 3 and moving the pine rings 4 from the neck toward the shoulders, the large diameter pine surge is applied to the shoulders before the small diameter side rollers 5. Unlike when the side rollers 5 first contact the shoulder, the kneading ring 4 touches the shoulder gently and does not cause pain.

In addition, the handle bar 16 provided at one end of the bed 1 is
It is provided so that a person on the bed 1 can grasp this handle bar 16 to prevent the body from shifting due to the movement of the pine surge member 3 when performing rubbing pine surgery. The lower end is fixed to one end of the bed 1. Also pillow 15
When massaging the neck and shoulders, it is better to remove this and lower the head position so that the massaging ring 4 will come into contact with the massaging ring 4 better and the massaging effect will be more effective. When in use, the handle bar 16 is folded aside, and the width of the base of the handle bar 16 is made shorter than the width of the pillow 15, and the pillow 15 is held on the base of the handle bar 16 when not in use. When the pillow 15 is to be used again, the person on the bed 1 can set the pillow 15 on the bed 1 by extending his hand while lying on his back.

As described above, the present invention is characterized in that the side rollers that support the body lying supine on the bed on both sides of the massage ring are arranged at a position offset from the rotation axis of the massage ring to the part where the head is located at one end of the bed. When massaging the area from the neck to the shoulders with a kneading ring, the side rollers are positioned next to the head and do not come into contact with the shoulders and lift the shoulders as in the past, and as a result, the side rollers interfere with the massage. There is an advantage that pine surgery can be performed effectively in this area using the fir ring without causing any damage.
