Patent Application
20220062094
The present invention relates to a massaging apparatus and, more particularly, to a mat (or pad) transmission structure.
A conventional massaging structure was disclosed in the Taiwanese Patent Publication No. M580961, and comprises two massaging rollers 10, base 20, a massaging roller motor 33, a swinging motor 34, and a swinging aim 30. Each of the two massaging rollers 10 includes two circular disks 11 and multiple massaging units 12 mounted between the two circular disks 11. Each of the two circular disks 11 has multiple through holes 112. A shaft 111 is connected between the two circular disks 11. Each of the massaging units 12 includes an elastic thread 121 and multiple massaging balls 122. The elastic thread 121 extends through the massaging balls 122 and is secured to each of the through holes 112 of each of the two circular disks 11 such that each of the massaging units 12 is mounted between the two circular disks 11.
The conventional massaging structure has the following disadvantages.
1. When the massaging roller motor 33 and the swinging motor 34 are started, each of the massaging units 12 is driven and rotated by the massaging roller motor 33, and the swinging arm 30 is driven and moved by the swinging motor 34, such that the two massaging rollers 10 are moved to massage the user's lower body. However, the conventional massaging structure is not expandable and cannot be used to massage the other part of the user.
2. The two massaging rollers 10 are mounted on the two sides of the massaging end 31. The swinging arm 30 has a determined weight to support the two massaging rollers 10 such that the two massaging rollers 10 can be rotated relative to the base 20. In addition, the massaging roller motor 33 and the swinging motor 34 are mounted in the swinging arm 30 to increase the weight of the swinging arm 30. Further, the two massaging rollers 10 and the swinging arm 30 are mounted on the base 20 to increase the volume and weight of the base 20. Thus, the conventional massaging structure is heavy and is not carried easily.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a mat transmission structure that is expandable and is placed on any plane to provide a massaging effect to any part of the user's body.
In accordance with the present invention, there is provided a mat transmission structure comprising a first body, a plurality of first operation units, and a power unit. The first body is provided with a first recess and a plurality of first pivot portions. The first operation units are pivotally mounted in the first recess. Each of the first operation units is pivotally mounted on each of the first pivot portions. The first operation units are rotated simultaneously in the first recess. Each of the first operation units includes a rod, a plurality of first operation members, and a first driving member. The rod is provided with a first fitting portion, two first pivoting sections, and a first mounting portion. Each of the first operation members is provided with a first surface and a second fitting portion. The first driving member is mounted on the first mounting portion. The power unit drives the first driving member of each of the first operation units such that each of the first operation units is rotated in the first recess.
According to the primary advantage of the present invention, the mat transmission structure is placed on any plane. Thus, when any part of the user's body rests on the mat transmission structure, the mat transmission structure provides a patting and massaging effect to the user. The mat transmission structure is expandable, and multiple mat transmission structures are provided and arranged linearly to provide a massaging effect to more parts of the user's body.
According to another advantage of the present invention, the eccentric construction is defined between the second fitting portion and each of the first operation members, such that the first surface of each of the first operation members has a height variation when the rod and the first operation members are rotated. Thus, the first operation members of each of the first operation units are mounted at the same angle or at different angles such that when each of the first operation units is rotated, the first surfaces of the first operation units are flush or not flush with each other. In such a manner, the second surfaces of the second operation units are driven by the first operation units and in turn moved to press and massage the user's body.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

When the toothed rack is moved linearly and reciprocatingly, the first driving member 23 is driven and rotated through an angle in the clockwise or anticlockwise direction such that each of the first operation units 20 is rotated through an angle. Alternatively, the first driving members 23 of the first operation units 20 engage each other, and the power unit 30 drives and rotates one of the first driving members 23.
In another embodiment of the present invention, the length of the first body 10 and the rod 21 is substantially equal to that of a bed, such that the mat transmission structure functions as a bed.
Accordingly, the mat transmission structure has the following advantages.
1. The mat transmission structure is placed on any plane. Thus, when any part of the user's body rests on the mat transmission structure, the mat transmission structure provides a patting and massaging effect to the user. The mat transmission structure is expandable, and multiple mat transmission structures are provided and arranged linearly to provide a massaging effect to more parts of the user's body.
2. The mat transmission structure is placed on any plane. Thus, when any part of the user's body rests on the first surfaces 221 of the first operation units 20, the power unit 30 is driven to drive and rotate the first operation units 20 which drive the first surfaces 221 to pat and massage the user.
3. The mat transmission structure is placed on any plane. Thus, when any part of the user's body rests on the second surface 511 of each of the second operation units 50, the power unit 30 is driven to drive and rotate the first operation units 20 which simultaneously drive the fourth driving member 52 and the second receiving portion 513 of each of the second operation units 50 to move upward and downward in each of the first receiving portions 41, such that the second surface 511 of the second operation member 51 is moved upward and downward to pat and massage the user.
4. The eccentric construction is defined between the second fitting portion 222 and each of the first operation members 22, such that the first surface 221 of each of the first operation members 22 has a height variation when the rod 21 and the first operation members 22 are rotated. Thus, the first operation members 22 of each of the first operation units 20 are mounted at the same angle or at different angles such that when each of the first operation units 20 is rotated, the first surfaces 221 of the first operation units 20 are flush or not flush with each other. In such a manner, the second surfaces 511 of the second operation units 50 are driven by the first operation units 20 and in turn moved to press and massage the user's body.
5. Each of the first operation units 20 only includes the rod 21, the first operation members 22, and the first driving member 23, such that each of the first operation units 20 has a simplified construction, and each of the first operation members 22 has a height variation.
6. The mat transmission structure presents a cubic or cuboid seat with a flat shape after assembly to facilitate storage, transportation and packaging of the mat transmission structure.
7. The power mechanism 33 drives the third driving member 34 which drives the second driving member 32 which drives the drive shaft 31, and the drive portion 311 drives the first driving member 23 of each of the first operation units 20 such that each of the first operation units 20 is rotated.
8. The fourth driving member 52 presses the first surface 221 each of the first operation members 22. The power unit 30 drives and rotates each of the first operation units 20, and each of the first operation units 20 drives the fourth driving member 52 and the second receiving portion 513 of each of the second operation units 50 to move upward and downward in each of the first receiving portions 41, such that the second surface 511 of the second operation member 51 is moved upward and downward. The fourth driving member 52 of each of the second operation units 50 is rotated relative to each of the first operation members 22 to enhance the lifetime thereof.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
