Description

Technical Field

[0001] The present invention relates to a lifting structure of a leg massage roller of a massage chair, and more particularly to a lifting structure of a leg massage roller of a massage chair that realizes smooth mechanism operation and stable center of gravity.

Background Art

[0002] As shown in FIGS. 9 and 10, a conventional leg massager of a massage chair includes a base (70), a massage piece (80), and a chair (90). The base (70) is fixed to the bottom of the chair (90), and a power source (81) is provided in the massage piece (80). By rotating the crank (82), the link (83) can be moved, and the link (83) and the base (70) are pivotally connected. A user can sit on the chair (90), and through the cooperation of the massage piece (80), the crank (82), and the link (83), the mechanism operates to rotate and lift the massage piece (80) to massage the feet. However, it is not difficult to understand that such a structure has the following problems, that is, the massage piece (80) and the base (70) are supported only by the crank (82) and the link (83), and the power source (81) is provided in the massage piece (80). Therefore, the center of gravity of the structure is increased. When the weight of the user's feet is applied to the massage piece (80), when the power source (81) rotates, it must simultaneously resist gravity, and there is a risk that the mechanism operation of the crank (82) and the link (83) may not be performed smoothly, and the operation of the massage piece (80) is not smooth, and the massage effect cannot be achieved.

[0003] Therefore, in view of this, the inventor has come up with the idea of the invention, designed it with years of experience, and after many discussions, sample trial production tests, and several modifications and improvements, the present invention has been completed.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention provides a lifting structure for a leg massage roller of a massage chair, which can achieve smooth mechanism operation and a stable center of gravity effect, and can massage the sole of the foot more smoothly.

Means for Solving the Problems

[0005] The present invention provides a lifting structure for a leg massage roller of a massage chair. The structure includes a leg massage mechanism and a chair. The leg massage mechanism has a fixed base, and the fixed base is coupled to the bottom of the chair. A power source part and a pivot base are provided on the fixed base. A rotating frame is provided at the bottom of the massage device, and a massage motor is provided inside the massage device. Massage rollers rotate on the left and right sides of the massage motor respectively. The rotating frame is pivotally connected to the pivot base. A power motor is provided in the power source part, and rocker arms rotate on the left and right sides of the power motor respectively. The rocker arms are pivotally connected to a push rod, and the push rod is pivotally connected to the rotating frame. When in use, when a user sits on the chair and leans the sole of the foot against the massage roller, when the power motor moves and rotates the rocker arm, the rocker arm interlocks the push rod to perform a mechanism operation, pushing and pulling the rotating frame, thereby repeatedly rocking the massage device back and forth, kneading the sole of the foot with the massage roller, and achieving a massage effect.

[0006] Here, it is preferable that only the massage device of the leg massage mechanism protrudes in front of the chair, and all other parts are provided under the chair.

[0007] Here, it is preferable that the chair is a folding chair.

[0008] In the first main object of the present invention, the power source part is fixed to the fixed base, and the massager is pivotally connected to the pivot base, so that the weight can be dispersed and the center of gravity can be made more stable. Also, the power motor pushes and pulls the massager, repeatedly moving it back and forth and shaking it, making the mechanism operation more stable and less affected. Further, when a user sits on the chair, the center of gravity of the leg massager is further stabilized, and the stability when the leg massager is used can be improved.

[0009] In the second main object of the present invention, the power source part is fixed to the fixed base, and the massager is pivotally connected to the pivot base. In this way, the power motor cooperates with the rocker arm and the push rod to push, pull and rotate the massager in a more horizontal direction, making the mechanism operation more stable. Even if the weight received by the massager becomes larger, it does not affect the operation of the leg massager. Other objects, advantages, and features such as the novelty of the present invention will become more apparent from the following detailed description and the related drawings.

Embodiments for Carrying Out the Invention

[0011] In order to better understand and recognize the object, features, and effects of the present invention, the following will be described in detail with reference to the drawings in a brief description of the drawings.

[0012] First, as shown in FIGS. 1 to 3, the present invention provides a lifting structure for a leg massage roller of a massage chair. The structure includes a leg massage machine (10) and a chair (20). The leg massage machine (10) has a fixed base (11), and the fixed base (11) is coupled to the bottom of the chair (20). A power source unit (12) and a pivot base (13) are provided on the fixed base (11). A rotating frame (141) is provided at the bottom of the massager (14), and a massage motor (142) is provided inside the massager (14). Massage rollers (143) rotate on the left and right sides of the massage motor (142). The rotating frame (141) is pivotally connected to the pivot base (13). A power motor (121) is provided in the power source unit (12). Rocker arms (15) rotate on the left and right sides of the power motor (121). The rocker arms (15) are pivotally connected to a push rod (16), and the push rod (16) is pivotally connected to the rotating frame (141). As shown in FIGS. 4 to 6, when in use, when a user sits on the chair (20) and leans the sole of the foot against the massage roller (143), when the power motor (121) moves and rotates the rocker arm (15), the rocker arm (15) interlocks the push rod (16) to perform a mechanism operation, pushing and pulling the rotating frame (141), thereby repeatedly reciprocating and shaking the massager (14), and kneading the sole of the foot with the massage roller (143) to achieve a massage effect.

[0013] According to the above structure, the power source unit (12) is fixed to the fixed base (11), and the massager (14) is pivotally connected to the pivot base (13). In this way, the weight can be dispersed, the center of gravity can be made more stable, and the power motor (121) can push and pull the massager (14) and repeatedly move it back and forth, making the mechanism operation more stable and less affected. Also, when a user sits on the chair (20), the center of gravity of the leg massager (10) can be further stabilized, and the stability of the leg massager (10) when in use can be improved.

[0014] Subsequently, as shown in FIGS. 4 to 6, which are schematic diagrams showing the mechanism operation when the present invention is actually used, when the massager (14) is in the initial position and the power motor (121) moves and drives the rocker arm (15), the rocker arm (15) rotates to push and move the push rod (16), and further push and move the rotating frame (141). As a result, the massager (14) pivotally rotates and can be pushed forward. Then, when the rocker arm (15) rotates to pull the push rod (16), the push rod (16) pulls the rotating frame (141), causing the massager (14) to pivotally rotate and return. The pivotal rotation flow of the massager (14) matches the shape of the feet that naturally hang down when the body is sitting, and the repeated back-and-forth lifting and lowering movement of the massage roller (143) can evenly massage the sole of the foot.

[0015] Since the power source unit (12) is fixed to the fixed base (11) and the massager (14) is pivotally connected to the pivot base (13), the power motor (121) can cooperate with the rocker arm (15) and the push rod (16) to push, pull, and rotate the massager (14) in a more horizontal direction, making the mechanism operation more stable. Even if the weight received by the massager (14) becomes larger, it will not affect the operation of the leg massager (10).

[0016] As shown in FIG. 7, which is another embodiment of the present invention, the present invention provides a lifting structure for the leg massage roller of a massage chair. In the leg massage machine (10), only the massage device (14) protrudes in front of the chair (20), and all other parts are provided under the chair (20). Therefore, it is possible to prevent the user's hair or trousers from being caught by the mechanism operation of the leg massage machine (10) and causing danger.

[0017] As shown in FIG. 8, which is yet another embodiment of the present invention, the present invention provides a lifting structure for the leg massage roller of a massage chair, and the chair (20) is a folding chair.

[0018] The above is only one embodiment of the present invention and does not limit the scope of implementation of the present invention. That is, changes, modifications, etc. made within the scope of the claims of the present invention should also belong to the scope of the present invention.
