Description

Technical Field

[0001] The present invention relates to a lifting structure of a leg massage wheel of a massage chair, and more particularly to a lifting structure of a leg massage wheel of a massage chair with smooth mechanism movement and stable center of gravity. Background Art

[0002] The existing leg massager of a massage chair is composed of Figure 9 and Figure 10 As shown, it includes a base 70, a massage member 80, and a chair body 90. The base 70 is fixed to the bottom of the chair body 90. A power source 81 is provided inside the massage member 80 to rotate a crank 82 to drive a connecting rod 83. The connecting rod 83 is pivotally connected to the base 70. A user can sit on the chair body 90. Through the cooperation of the massage member 80, the crank 82, and the connecting rod 83, the mechanism can move to pivot and lift the massage member 80 to massage the legs. However, it can be easily seen that such a structure has the following problems: The massage member 80 and the base 70 are only supported by the crank 82 and the connecting rod 83, and the power source 81 is provided inside the massage member 80, which raises the center of gravity of the structure. When the weight of the user's legs is applied to the massage member 80, the power source 81 also has to resist gravity when rotating, which may cause the crank 82 and the connecting rod 83 to fail to perform the mechanism movement normally, resulting in the massage member 80 moving smoothly and unable to achieve the massage effect.

[0003] Therefore, in view of this, the inventor has come up with the idea of the invention, and then designed it with years of experience, discussed it in many ways, made sample tests, and made multiple corrections and improvements, and finally launched the present invention. Summary of the Invention

[0004] Technical problem to be solved:

[0005] The present invention provides a lifting structure of a leg massage wheel of a massage chair, which has the effects of smooth mechanism movement and stable center of gravity, and can massage the inner side of the legs more smoothly.

[0006] Technical features for solving the problem:

[0007] The present invention provides a lifting structure for the leg massage wheels of a massage chair, which includes a leg massage machine and a seat. Among them, the leg massage machine has a fixed base, which is combined with the bottom of the seat. A power source part and a pivot seat are provided on the fixed base. A pivot frame is provided at the bottom of a massager. A massage motor is provided inside the massager. A massage wheel rotates on each side of the massage motor. The pivot frame is pivotally connected to the pivot seat. A power motor is provided inside the power source part. A rocker arm rotates on each side of the power motor. The rocker arm is pivotally connected to a push-pull rod, and the push-pull rod is pivotally connected to the pivot frame. When in use, when the user sits on the seat and leans the inner side of the leg against the massage wheel, when the power motor drives the rocker arm to rotate, the rocker arm drives the push-pull rod to perform a mechanism movement to push and pull the pivot frame, so that the massager swings back and forth, and the massage wheel presses the inner side of the leg to achieve the massage effect.

[0008] Optionally, only the massager of the leg massage machine protrudes from the front side of the seat, and the rest are located under the seat.

[0009] Optionally, the seat is a folding chair.

[0010] The first main object of the present invention is that the power source part is fixed on the fixed base, and the massager is pivotally arranged on the pivot seat, so that the weight is dispersed and the center of gravity is more stable. Moreover, the power motor pushes and pulls the massager to swing back and forth, and its mechanism movement is more stable and not easily disturbed. When the user sits on the seat, the center of gravity of the leg massage machine can be further stabilized, and the stability of the leg massage machine during use can be improved.

[0011] The second main object of the present invention is that the power source part is fixed on the fixed base, and the massager is pivotally arranged on the pivot seat. Therefore, the power motor can push, pull, pivot and rotate the massager in a relatively horizontal direction in cooperation with the rocker arm and the push-pull rod, and the mechanism movement is also more stable. Even if the massager bears a large weight, it will not affect the operation of the leg massage machine.

[0037] To further understand and recognize the purpose, features, and effects of the present invention, the following is a detailed description in conjunction with the [Brief Explanation of the Drawings] as follows:

[0038] First, please refer to Figures 1 to 3 As shown, the present invention provides a lifting structure for the leg massage wheels of a massage chair, which includes a leg massager 10 and a seat 20. Among them, the leg massager 10 has a fixed base 11, and the fixed base 11 is combined with the bottom of the seat 20. A power source part 12 and a pivot seat 13 are provided on the fixed base 11. A pivot frame 141 is provided at the bottom of a massager 14, and a massage motor 142 is provided inside the massager 14. A massage wheel 143 is rotated on each side of the massage motor 142. The pivot frame 141 is pivotally connected to the pivot seat 13. A power motor 121 is provided inside the power source part 12, and a rocker arm 15 is rotated on each side of the power motor 121. The rocker arm 15 is pivotally connected to a push-pull rod 16, and the push-pull rod 16 is pivotally connected to the pivot frame 141. From Figures 4 to 6 As shown, when in use, when the user sits on the seat 20 and leans the inner side of the leg against the massage wheel 143, when the power motor 121 drives the rocker arm 15 to rotate, the rocker arm 15 drives the push-pull rod 16 to perform a mechanism movement to push and pull the pivot frame 141, so that the massager 14 swings back and forth, and the massage wheel 143 presses the inner side of the leg to achieve a massage effect.

[0039] Through the above structure, the power source part 12 is fixed on the fixed base 11, and the massager 14 is pivotally arranged on the pivot seat 13, so that the weight is dispersed and the center of gravity is more stable. Moreover, the power motor 121 pushes and pulls the massager 14 to swing back and forth, and its mechanism movement is more stable and not easily interfered. Also, when the user sits on the seat 20, the center of gravity of the leg massager 10 can be further stabilized, and the stability of the leg massager 10 during use can be improved.

[0040] Again, refer to Figures 4 to 6 As shown, it is a schematic diagram of the mechanism movement during the actual use of the present invention. When the massager 14 is in the initial position, when the power motor 121 rotates to drive the rocker arm 15, the rocker arm 15 will rotate and push the push-pull rod 16, and then push the pivot frame 141, so as to pivot and push the massager 14 forward. Then, when the rocker arm 15 rotates and pulls the push-pull rod 16, the push-pull rod 16 will pull the pivot frame 141 to pivot and pull the massager 14 back. The pivoting process of the massager 14 conforms to the natural shape of the leg when sitting down, and the massage wheel 143 can completely move up and down to massage the inner side of the leg back and forth.

[0041] The power source unit 12 is fixed on the fixed base 11, and the massager 14 is pivotally arranged on the pivot seat 13. Therefore, the power motor 121, in cooperation with the rocker arm 15 and the push-pull rod 16, can push and pull and pivot the massager 14 in a relatively horizontal direction, making the movement of the mechanism more stable. Even if the massager 14 bears a large weight, it will not affect the operation of the leg massager 10.

[0042] As Figure 7 shown, this is another embodiment of the present invention. The present invention provides a lifting structure for the leg massage wheels of a massage chair. Among them, only the massager 14 of the leg massager 10 protrudes from the front side of the seat 20, and the rest are located under the seat 20, so that the user will not be involved in hair or trouser skirts due to the movement of the mechanism of the leg massager 10, causing danger.

[0043] As Figure 8 shown, this is yet another embodiment of the present invention. The present invention provides a lifting structure for the leg massage wheels of a massage chair. Among them, the seat 20 is a folding chair.

[0044] The above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of implementation of the present invention; that is, all equivalent changes and modifications made according to the scope of the patent application of the present invention should still fall within the scope covered by the patent of the present invention.
