The double roller guide device for transferring the massage module according to the present invention as described above will be described with reference to the accompanying drawings.

First, if the terms used in this specification are defined, upper contact and lower contact refer to the contact point between the roller and the rail, and the case where the top dead center of the roller is in contact with the rail is It is called 'top contact', and the case where the rail is located below the roller and the bottom dead point of the roller is in contact with the rail is called 'bottom contact'.

As shown in Figures 1 to 4, the double roller guide device for transporting the massage module according to the present invention includes a guide rail 10 having a main rail 11 and an auxiliary rail 13 spaced apart from each other on the left and right, and a guide Includes a transfer roller 20 composed of a main roller 21 sliding along the main rail 11 of the rail 10 and an auxiliary roller 23 sliding the auxiliary rail 13 of the guide rail 10 It is composed by

First, the double roller guide device according to the present invention is configured so that rollers are mounted on both sides of the massage module 1, and guide rails 10 are formed on the massage device body so that the rollers can slide along the guide rails 10.

In this case, the power transmission method for moving the massage module 1 can be divided into a method of directly transmitting power to the massage module 1 and a method of directly driving a roller.

In the method of directly transmitting power to the massage module 1, sprockets are provided on the front and rear of the main body, a motor is mounted on one sprocket to drive rotation, and a chain or time connecting the sprockets and the massage module 1 is provided. This is the case where the massage module is driven by a belt or the like.

In this case, the roller serves to support the movement of the massage module 1.

In addition, a method of directly driving the roller is a method in which a motor is mounted on the massage module 1 to directly drive the roller, and if necessary, a massage module by replacing the roller with a pinion gear and the guide rail 10 with a rack gear. There is a way to move (1), etc.

The power transmission method of the double roller guide device according to the present invention introduces a method of directly transmitting power to the massage module 1, but the latter power transmission method of directly driving the rollers through a simple design change can be adopted is of course

In general, in a conventional guide device for moving the massage module 1, one roller drives the massage module 1 by moving along the guide rail 10 injection-molded on the main body. In this case, the guide rail 10 ) The upper part is provided with a guide that is not in contact with the roller.

This guide is introduced for the purpose of preventing separation of the roller and preventing contact between the roller and other components of the massage device.

However, when the massage device is used, when the user's load acts, the injection-molded guide also directly or indirectly receives the user's load, so that the bending or deflection of the guide occurs.

In this case, contact between the guide and the roller may occur due to bending or deflection of the guide. A phenomenon in which the roller is caught may occur.

In this case, the roller may move without rotation due to the pressure of the guide rail 10 and the guide. As a result, the roller, the guide rail 10 and the guide may be worn due to mutual friction, or noise may be generated. In severe cases, problems such as failure of the driving device or operation errors may occur due to an overload acting on the motor or the rotating shaft 3 connected to the roller due to the pressure caused by the guide rail 10 and the guide.

Particularly, in the case of rollers, uneven wear may occur, and uneven wear of these rollers may affect the running of the rollers, hinder smooth movement, and cause inconvenience in use.

In addition, when such abrasion is severe, there may be a problem of dust generation and scattering, and in order to solve the problem of dust and dust scattering, work for maintenance of the device must be performed frequently, so unnecessary maintenance There are problems such as cost and time consumption due to maintenance work.

Therefore, hereinafter, the double roller guide device according to the present invention proposed to solve the conventional problems as described above will be described in more detail.

First, as shown in FIGS. 1 to 4, the guide rail 10 according to the present invention is disposed on both sides of the main body and has a double rail structure.

The guide rail 10 for this purpose is composed of a main rail 11 disposed on the lower part and an auxiliary rail 13 disposed on the upper part, and the main rail 11 and the auxiliary rail 13 are virtually drawn between them. It is arranged on one side and the other side based on the vertical line.

In addition, the guide rail 10 is disposed on the main rail 11 or the auxiliary rail 13, or both, and guides 15 and 17 for preventing contact between the main roller 21 and the auxiliary roller 23 are provided. are provided

The guide according to the present invention includes a first guide 15 connected to the side of the auxiliary rail 13 and a second guide 17 connected to the side of the main rail 11.

1 to 4, the conveying roller 20 according to the present invention is mounted on both sides of the massage module 1 and is configured to correspond to the guide rail 10 of the double rail structure.

That is, the conveying roller 20 is in contact with the main roller 21 that is in lower contact with the main rail 11 of the guide rail 10 and the auxiliary rail 13 of the guide rail 10. It consists of an auxiliary roller 23 that does.

In this case, the main roller 21 and the auxiliary roller 23 are mounted on the rotational shaft 3 provided in the massage module 1, and the auxiliary roller 23 is rotatably connected to the rotational shaft 3 so that the main roller ( 21), that is, it is configured to be capable of relative rotation.

In addition, the first guide 15 of the guide rail 10 is disposed above the main roller 21 so as not to contact the main roller 21, and the second guide 17 is an auxiliary roller so as not to contact the auxiliary roller 23. (23) is placed at the bottom.

In the dual roller guide device configured as described above, the main roller 21 moves along the main rail 11 and serves to directly move the massage module 1 regardless of the power transmission method.

In particular, when the user's load acts on the auxiliary roller 23 during use of the massage device, the auxiliary rail 13 disposed on the top also receives the user's load, and at this time, the auxiliary rail 13 is bent by a predetermined amount, Deflection occurs, and at this time, the auxiliary roller 23 supports the bending or deflection of the auxiliary rail 13.

In this case, since the contact point between the main rail 11 and the main roller 21 and the contact point between the auxiliary rail 13 and the auxiliary roller 23 are located at different points up and down, the load bearing points of each roller are two different points. occurs at the point.

Therefore, since the load acting from the top is distributed to different points between the main rail 11 and the main roller 21, and between the auxiliary rail 13 and the auxiliary roller 23, the applied load of the main roller 21 can be reduced. be able to

At the same time, since the auxiliary roller 23 supports the auxiliary rail 13, contact between the main roller 21 and the first guide 15 is prevented by supporting the bending or deflection of the auxiliary rail 13, and the main By supporting the load by the roller 21, contact between the auxiliary roller 23 and the second guide 17 can be prevented.

In this case, as shown in FIG. 5, when the contact force between the auxiliary rail 13 and the auxiliary roller 23 is large due to the bending or deflection of the auxiliary rail 13, or the auxiliary roller 23 is the second guide ( 17), a phenomenon such as being caught between the auxiliary rail 13 and the second guide 17 may occur.

In this case, since the auxiliary roller 23 can be driven independently of the main roller 21, the pressure applied to the auxiliary roller 23 by the auxiliary rail 13 or the auxiliary rail 13 and the second guide 17 According to this, the auxiliary roller 23 rotates in reverse or is not driven to rotate, and is movable.

Therefore, during the operation of the massage module 1, the main roller 21 as well as the auxiliary roller 23 can prevent wear due to friction with rails or guides, generation of dust and noise.

In addition, the conveying roller 20 according to the present invention is configured to prevent contact between the main roller 21 and the auxiliary roller 23 and is provided with a spacer 40 in the form of a bush.

That is, the spacer 40 is disposed between the main roller 21 and the auxiliary roller 23 to maintain a constant distance between the main roller 21 and the auxiliary roller 23, thereby preventing contact between the rollers 21 and 23. This can ensure smooth operation.

In addition, the space 40 maintains the distance between the rollers 21 and 23 so that the outer surface of the main roller 21 where the main roller 21 and the auxiliary roller 23 face each other is the main rail 11 and the second By preventing the guide 17 from contacting the wall that divides it, it plays a role in fundamentally blocking the generation of noise due to contact between the main roller 21 and the wall or generation of dust due to abrasion during the operation of the guide device. do.

Furthermore, the double roller guide device according to the present invention can be modified in various forms,

First, as described above, the main roller 21 and the auxiliary roller 23 become the main roller 21 when they are in contact with the main rail 11 according to the position in contact with the main rail 11 and the auxiliary rail 13 , The case of contacting the auxiliary rail 13 becomes the auxiliary roller 23.

In addition, the main roller 21 and the auxiliary roller 23 of the conveying roller 20 can be arranged in various forms according to the diameter, and the diameters of the main roller 21 and the auxiliary roller 23 of the conveying roller 20 are mutually As another case, as shown in FIG. 2, the main roller 21 is manufactured with a relatively small diameter compared to the auxiliary roller 23, and as shown in FIG. 3, the main roller 21 is auxiliary. Compared to the roller 23, there are cases in which it is manufactured with a relatively large diameter.

In this case, when the diameters of the main roller 21 and the auxiliary roller 23 are different from each other, as described above, the contact position of each roller, the main rail 11 and the auxiliary rail 13 and the position of the conveying roller and the guide rail Various modifications are possible depending on the placement position.

In this case, in the illustration of FIG. 2 (a) and (a) of FIG. 3, the main rail and the main roller are disposed on the outside, and the auxiliary rail and the auxiliary roller are disposed on the inside. (b) and (b) of FIG. 3 shows a case in which the main rail and the main roller are arranged on the inside, and the auxiliary rail and the auxiliary roller are arranged on the outside.

In addition, when the diameters of the main roller 21 and the auxiliary roller 23 of the conveying roller 20 are the same, as shown in FIG. 4, the contact position between the main rail 11 and the auxiliary rail 13 and the conveying roller Depending on the arrangement position of the guide rail, the main roller 21 is in contact with the main rail 11, and the auxiliary roller 23 is in contact with the auxiliary rail 13.

On the other hand, a certain clearance may be generated between both side surfaces of the massage module 1 and the guide rail 10, especially the upper guide rail 10, by each roller sliding the guide rail 10 according to the present invention. The clearance may not only cause the movement of the massage module 1 in both directions during driving of the massage module 1, but also cause each roller to be separated from the guide rail 10, or the massage module 1 and the guide rail (10) Noise due to friction between them may be generated.

In order to solve this problem, an annular separation prevention member 30 is mounted on the main roller 21 or the auxiliary roller 23 of the conveying roller 20 according to the present invention, and the separation prevention member 30 is a massage module. The guide rail 10 disposed on the side and top of (1) is spaced apart so that it can be maintained at regular intervals.

In this case, the separation preventing member 30 is formed in a form protruding vertically from the inside of the roller disposed inside of the main roller 21 and the auxiliary roller 23, that is, the roller close to both sides of the massage module 1.

Therefore, by the anti-separation member 30, the massage module 1 can travel without flow, and friction between the massage module 1 and the guide rail 10 can be eliminated, as well as being transported from the guide rail 10. It is possible to prevent the roller 20 from being separated.

In the above description of the dual roller guide device for transporting the massage module of the present invention with reference to the accompanying drawings, the specific shape and direction have been mainly described, but the present invention is capable of various modifications and changes by those skilled in the art, and these modifications and changes It should be construed as being included in the scope of the present invention.
