Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to massage machines, especially the shafts of massage rollers, etc. This relates to a receiving device.

0002

[Conventional technology]

Conventionally, multiple rollers were attached to the outer circumferential surface of a cylindrical body arranged horizontally, and motor-driven The cylinder is rotated and the foot or calf placed on the cylinder is struck by vibration. Massage machines that provide relief are known. Also, a massager in which a pair of disc-shaped massage members are attached to the main shaft arranged horizontally. Machines are also known. The massaging member has opposing surfaces inclined in opposite directions, and It is formed so that the distance between the massaging members can be adjusted. User is calf etc. Adjust the spacing of the kneading members appropriately according to the width of the The kneading member rotates together with the main shaft, and the opposing surfaces of the inclined kneading member open and close. It has a kneading effect.

0003 Furthermore, it is equipped with a roller and a kneading member, and can perform multiple roller massages and kneading massages. Massage machines with the following functions are also known.

0004

[Problem that the idea aims to solve]

The massage machine mentioned above massages the human body by contacting the rollers or massaging members. Corresponds to both the radial direction and thrust direction for the main axis of movable, roller and fir members. load is applied. Therefore, bearings are required to have sufficient load-bearing performance. Also, kneading parts Massage machines that can adjust the spacing have a lead screw inside the main shaft to adjust the spacing. The main shaft and lead screw rotate independently, so the bearing The configuration is complicated and the cost is high.

[0005] Therefore, we provide a bearing device with a simple structure and high load-bearing performance, which is low cost. Technical issues that need to be solved arise in order to reduce The purpose is to decide.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, this idea is based on the shape of a pipe driven by a motor. A lead screw is arranged coaxially within the shaft, and a slider is screwed onto the lead screw. A massager in which a key is engaged with a key groove drilled in the main shaft and is loosely fitted into the main shaft. In a massage machine in which a member is coupled to the slide key so as to be freely movable in the axial direction. , forming a double-structured cap consisting of a bearing part and an outer cylinder part, and extending the cap to both ends of the main shaft, respectively. When the outer cylindrical part of the cap is mounted and the lead screw is supported by the bearing part, In both cases, a bearing that fits into the outer cylindrical portion is fixed to the massage machine main body, and the main shafts are aligned. A massage machine characterized by having a lead screw pivotally supported. This is a proposal.

[0007]

[Effect]

A lead housed in the main shaft connects to the bearing part of a pair of caps consisting of a bearing part and an outer cylindrical part. Insert both ends of the screw, and attach the outer cylinder to both ends of the main shaft. massager Attach the bearing that fits the cap to the main body of the machine, loosely fit the cap, and connect the main shaft and A lead screw is pivoted in place.

[0009] The main shaft 7 passes through the input gear case 10 in the center, and has a wall in the center as shown in FIG. Power is supplied via a worm gear 12 fitted with a worm wheel 11 and connected to a motor 4. is transmitted. A cylindrical body that is a massage member loosely fitted on the main shaft 7 so as to be freely movable in the axial direction 13, 13 are large-diameter end plates 15 at both ends of the central cylindrical portions 14, 14 shown by chain lines in FIG. , 16, 15, and 16 are fixedly installed. Near the periphery of the end plates 15, 16, 15, 16 The rollers 17, 17..., 18, 18..., which are pivotally supported nearby, are arranged at appropriate intervals, and in this implementation In the example, wide rollers 17, 17... and short rollers 18, 18... are arranged at 60 degree intervals. are arranged alternately. In addition, 19, 19... are ribs provided in the central cylinder portions 14, 14. It is.

0010 The end faces of the inner end plates 16, 16 on the input gear case 10 side are inclined with respect to the main shaft 7. The inclined plates 20, 20 which are parallel to this end surface are protruded, and the inclined plates 20, 20 The kneading members 22, 22 are freely rotatably attached via ball bearings 21, 21 to the It is being The massaging members 22, 22 are rubber pressing pieces 2 provided with protrusions at appropriate intervals. 3 and 23 are attached to resin rings 24 and 24. Two massage members 22, 22 are inclined in opposite directions, so when the main shaft 7 is rotated by the motor 4, , the kneading members 22, 22 continuously open and close, and knead the human body such as the calf. Can be done.

[0011] FIG. 4 is an exploded view of the mechanism section 2. The main shaft 7 inserted into the input gear case 10 is hollow. It is a pipe, and 25, 25 are key grooves opened from both left and right ends toward the center. The inner diameters of the cylinders 13, 13 are approximately equal to the main shaft 7, and the cylinders 13, 13 can slide along the main shaft 7. 26 is a lead screw housed in the main shaft 7, and there are screws in opposite directions near the left and right ends. Threaded portions 27, 27 are carved. 28, 28 are outer ends of the cylinders 13, 13 It is a guide member that is fixed to the As shown in FIG. into the keyway 25 of the lead screw 26, and screw the threaded portion 27 of the lead screw 26 into the screw receiver 30. match. Then, the holding plates 32, 32 shown in FIG. 4 are screwed to the outer end plates 15, 15. Then, the guide members 28, 28 are fixed.

0012 Next, the bearing parts 34, 34 of the resin caps 33, 33 are screwed onto the lead screw 2. 6 to make the end of the lead screw 26 protrude, and the outer cylinder part 35, 35 is attached to the end of the main shaft 7. 36, 36 are fixed in the predetermined positions of the upper and lower cases 3, 8. It is a cap-shaped thrust bearing with a fixed diameter, and is mounted on the caps 33, 33. . 37 is a brake plate fixed to the left end of the lead screw 26; A rubber ring 38 is attached to the rubber ring 38.

[0013] 6 and 7 show the cap 33, in which the bearing part 34 and the outer cylinder part 35 are integrally molded. However, the inner diameter of the bearing portion 34 is formed to be able to pivotally support the lead screw 26. Ru. A radial engaging portion 39 is provided in the recess between the outer cylinder portion 35 and the bearing portion 34, as shown in FIG. 6, the engaging portion 39 is fitted into the keyway 25 of the main shaft 7 to connect the main shaft 7 and the cap. The top 33 rotates integrally with the top 33.

[0014] As shown in Fig. 1, the bearing fixing parts 9, 9 formed in the lower case 3 and upper case 8 The mechanism section 2 is attached by fitting the thrust bearings 36, 36 together. Fixed left bearing A solade 40 is fixed further to the left side of the portion 9, and a plunger ( The brake plate 37 is inserted into the inner peripheral part of the band brake 41 attached to the entered. When the solenoid 40 is energized, the band brake 41 is pulled downward, and the band brake 41 is pulled downward. It comes into pressure contact with the rake plate 37 to prevent the lead screw 26 from rotating.

[0015] When the motor 4 is energized, the main power is The shaft 7 is rotated. Engage the slide keys 29, 29 with the key grooves 25, 25 of the main shaft 7. The cylinder bodies 13, 13 rotate in conjunction with the main shaft 7. At this time, the solenoid 4 0 is turned off, the lead screw screwed into the guide members 28, 28 shown in FIG. -26 also rotates in conjunction with the cylinders 13,13. Now, turn on solenoid 40. When the lead screw 26 is braked, the guide rotates together with the cylinders 13, 13. The members 28, 28 are fed in opposite directions on the lead screw 26, and rotate the main shaft 7. Depending on the direction of rotation, the cylindrical bodies 13, 13 as a whole move to expand or approach each other, and the kneading members 22, 22 intervals can be adjusted freely. Forward/reverse rotation of the motor 4 mentioned above and solenoid The switch 40 is turned on/off by switches 42, 42, etc. arranged on the operation switch board 6. It is done by manipulation.

[0016] This invention may be modified in various ways as long as it does not depart from the spirit of this invention. Naturally, this invention extends to modified versions of these.
