Abstract

It is a kind of continuous movement and reciprocating transmission structure of a rolling compression massage device, the main part of which is a massage device installed on the middle part of the drive shaft with a bottom plate installed with a long rod-type drive shaft pedestal and a hole penetrating in the middle of the lower pedestal. Is configured. Among them, the middle part of the drive shaft is arranged so that the clockwise and counterclockwise two-way spiral bones intersect, forming a cross-shaped two-way spiral bar circulating at both ends. The middle part of the hole through the pedestal has a straight guide plate protruding from the bottom of the cylindrical interlocking piece that has been injected and installed above, so that it is properly engaged with the broken bone in the form of a spiral. This allows the drive shaft to rotate and at the same time the guide plate, which is inserted into the spiral bone of the drive shaft, circulates along the inner valley, causing the massager on the top to move continuously in the axial direction. In addition, the sliding goal, which consists of two-way spiral arrangements in the clockwise and counterclockwise direction, is characterized by achieving the continuous driving effect of the reciprocating stroke.

Description

Rolling compression massage device for continuous movement and reciprocation {ROLLING MASSAGE DEVICE CONTINUOUS MOTION RECIPROCAL DRIVE STRUCTURE}

The continuous movement and reciprocating transmission structure of the present invention compression compression massage device is for assembling a massage device or a massage device inside a chair or an object in contact with the body for back massage use, and the movement and reciprocation can be performed by a single axis direction. It is an electric drive to go forward.

This structure has shaft support at the top and bottom, and long rod drive shaft is installed between the shaft support at both ends to form the bottom plate. It consists of a massage device installed in the middle of the rod of the drive shaft by making a hole through the middle of the lower support plate.

Characteristically, the middle part of the drive shaft, located between the two shaft rests, is a cross-wise two-way spiral bar that circulates at both ends by alternately arranging two-way spiral grooves in a clockwise and counterclockwise direction.

The middle part of the hole through the base plate is equipped with a cylindrical interlocking piece injected from above. Thus, when the drive shaft rotates, the sliding goal on this cross-shaped two-way spiral bar realizes continuous rotation in a constant direction, allowing the guide plate fitted to this goal to circulate along the bone internal trajectory. This allows the base plate, the massage part on the top, to move continuously along the axial direction.

The clockwise and counterclockwise bidirectional spiral cross-circulating arrangements switch the direction of travel automatically each time it moves along the axial direction and reaches either end, resulting in a continuous drive effect of the reciprocating stroke.

And since the electrode does not need a positive / negative switching device, it can avoid the impact of electric current expansion that occurs during the instantaneous positive / negative electrode switching of the motor, which has a practical effect of extending the life of the motor.

In general, a massage device installed inside a massage chair or an object in contact with the body and used for the massage of the user's back should massage the large area of the entire back, so it must be reciprocated in the vertical direction to the back. Of driving design is required.

Easily seen in everyday life, this massage-type reciprocating device features two different rotational directions, one shaft in one rotational direction, or one using a shaft or a leather belt, chain, etc. The direction is used to create a linear reciprocating movement of the massage structure or massager, resulting in cost increases and equipment installation space. Therefore, there are many inconveniences in manufacturing and use, and it is not practical.

In addition, the one-way rotary drive unit is a current that undergoes a process in which the positive and negative poles are generated each time in contact with each end of the drive shaft reciprocating operation in a DC or AC motor driving the axial rotation. The control unit must be installed.

When the massage device is moved by using the rotational direction changer of the drive shaft, when it reaches either end, it moves back and forth. Although this structure saves cost and reduces the occupied area compared to the above-described method, the motor has a high current because the operation of the current is not avoided due to the instantaneous impact of instantaneous switching between the positive and negative poles each time. Due to the continuity impact of the low conversion, the life is shortened and the noise is caused by the high load caused by the torsion.

This phenomenon is caused by frequent back and forth massage of the back massage device under frequent use, which often causes motors used in these types of devices to fail or burn out. This is ineffective because of the inconvenience of repairing or replacing them, and the loss of money.

The main creative purpose of the present invention is to install only one long rod drive shaft between two shaft supports on the bottom plate, so that both the clockwise and counterclockwise two-way spiral slides are arranged in the middle of the drive shaft. Completing the cross-shaped bidirectional spiral rod structure that circulates the ends together, the guide plate protruding from the bottom of the cylindrical interlocking piece injected from above into the middle part of the hole penetrating the massage device support plate is fitted inside the sliding shaft of the drive shaft. Blows.

This allows the drive shaft to circulate internally along the two-way, two-way helical sliding goal, and the support plate with the massage part on top moves continuously along the axial direction. Since the helical sliding goal is a two-way spiral intersecting arrangement in a clockwise and counterclockwise direction, each time one end of the axial movement stroke is reached, the direction is automatically changed to create a continuous driving effect of the reciprocating stroke. It is. It is characterized by simple and economical structure with one motor and drive shaft.

The second creative purpose of the present invention is to fix the rotating shaft to rotate the rotating shaft when the motor rotates in the opposite direction by selecting the current supply of the opposite electrode in the connector for the one-way rotation control between the motor and the drive shaft. A method of vertex massage that causes the massage device to stop in its original position by deviating from its shape. This increases the type of change operation of the unit, and attains the multiple benefits of simple structure and operation effect.

The structure, features, effects and practical purpose of the present invention are explained in detail together with the drawings. See FIGS. 1, 2, 3, and 3A.

The present invention is suitable for assembling the inside of a chair or an object in contact with the body for back massage use, all massage devices or massage devices (2) used for back massage or physiotherapy of the user (of this massage device The structure type is not limited, and is not used for the purpose of the present invention), it is used for the pedestal, and proceeds continuously moving in one axial direction, and has a reciprocating electric structure.

The transmission structure has one shaft support 41 at the upper and lower ends, respectively, so that the bottom plate 4 and the support plate 21 are positioned so that the long rod-shaped drive shaft 3 is positioned between the support holes 411. It consists of a massage device (2) which has a hole (211) through the middle part and is inserted into the middle of the drive shaft (3).

Its characteristic is that the middle part of the drive shaft 3 located between the two shaft pedestals 41 has a clockwise spiral sliding goal 311 and a counterclockwise spiral sliding goal 312 intersecting and arranged between both ends. It consists of a revolving cross-shaped bidirectional spiral bar (31).

The middle part of the hole (211) penetrating the base plate is connected to the hole (22) made from the upper part, and a cylindrical interlocking piece (23) is installed in this hole. In addition, the fixing piece 231 at the upper end of the interlocking piece 23 is inserted through the center hole 2211 of the fixing lock cover 221 above the hole so that the interlocking piece 23 is inserted into the hole 22. To be fixed.

At the bottom of the interlocking piece (23), there is a straight guide plate (232), which is inserted into the clockwise spiral sliding goal (311) or the counterclockwise spiral sliding goal (312).

See FIGS. 3A and 4A, B, and C. According to the above-described structure, the drive shaft 3 rotates in the fixed direction by the motor 5 which directly transmits power or indirectly transmits power from the rear (indirect transmission type in which two umbrella-shaped gears in the figure are connected to each other). ), This crosswise two-way helix bar (31) also rotates continuously in a fixed direction.

Thus, the guide plate 232 inserted into the clockwise spiral sliding goal 311 and the counterclockwise spiral sliding goal 312 is moved along the direction of the sliding goal so that the supporting plate 21 of the massage device 2 is moved. To move them up (Figure 4a) or to move them down (Figure 4c).

It is arranged to circulate and intersect both ends of the clockwise helical sliding goal 311 and the counterclockwise helical sliding goal 312 of the crosswise bidirectional spiral bar 31, so that the delivery plate (at 232 to another slip goal (clockwise slip goal 311 to counterclockwise slip goal 312, or counterclockwise slip goal 312 to clockwise slip goal 311: see FIG. 4B). As you move, it automatically reverses the direction of the move and continues along the sliding goal. This causes the base plate 21 of the massage device 2 to move up or down (continuous stroke from b to c back in FIG. 4a, or b back to a in FIG. 4c).

Under the premise that it does not need to switch directions or arrange other parts by supplying current, the massage device 2 can massage the entire back part of the user in the axial direction of the drive shaft 3 so that the massage can be performed continuously and repeatedly. By enabling the operation, the effect of the automated operation of the massage device 2 is realized.

Furthermore, if the massage device is to be massaged while stopped at the position selected by the user during the reciprocating stroke of the massage device 2 (see FIGS. 1 and 2), the power transmission is performed between the motor 5 and the drive shaft 3. Gear is used to control the rotation in one direction.

In addition, there is an electric gear part at the top and the bottom, respectively, and it is a coupler (51) of a manual gear (3A) installed in front of the motor shaft (5a) and the drive shaft (3) in front of the motor (5) to transmit power. One-way clutch with directional drive rotation and counterclockwise orbital deviation or counterclockwise drive rotation and clockwise orbital deviation; it is well known as a structure that is installed in front of the motor shaft and the detailed structure is omitted.)

As such, when the user does not select the current supply of the opposite electrode, the motor 5 rotates in one direction and operates the drive shaft 3 as described above, thereby reciprocating the massage device 2 in the entire back portion of the user. And massage.

On the contrary, if the user selects the current supply of the opposite electrode (e.g., connects the operating electric circuit of the current supply of the opposite electrode to the selection button of the vertex massage additionally mounted on the operation panel), the motor 5 is reversed. When rotating in the direction, drive shaft 3 is out of the motorized relationship.

The massage device (2) thus performs a vertex massage in a fixed position that cannot be moved. This makes it possible to diversify the operation of the device and gain many benefits from the simple structure and operation.

In addition, the c-shaped position limiting track 42 formed on the bottom plate 4 by installing the fixed shaft rotating wheels 24 on both sides of the support plate 21 to further increase the stability during the movement of the massage device (2). (See Figures 1,2,3) This assists the massage device (2) with a stable effect on both the left and right sides of the reciprocating movement.
