Abstract
Description
[Technical Field]
[0001] The present invention relates to a leg massage roller lifting structure for a massage chair, and more particularly to a leg massage roller lifting structure for a massage chair that achieves smooth mechanical operation and a stable center of gravity. [Background technology]
[0002] As shown in Figures 9 and 10, a conventional leg massager for 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). A power source (81) is provided in the massage piece (80). A crank (82) is rotated to move a link (83), which pivotally connects the base (70). A user can sit on the chair (90). The massage piece (80), the crank (82), and the link (83) cooperate to operate the mechanism, causing the massage piece (80) to rotate and move up and down, thereby massaging the feet. It is easy to understand that such a structure has the following problems: the massage piece 80 and the base 70 are supported only by the crank 82 and link 83, and the power source 81 is installed inside the massage piece 80. Therefore, the center of gravity of the structure is elevated. When the weight of the user's feet is placed on the massage piece 80, the power source 81 must simultaneously resist gravity while rotating. This may cause the mechanism of the crank 82 and link 83 to not work properly, resulting in the massage piece 80 not working smoothly and failing to provide a satisfactory massage effect.
[0003] Therefore, the present inventors have taken this into consideration and conceived the concept of the invention, designed it based on their many years of experience, and completed the present invention after much discussion, prototype testing of samples, and several modifications and improvements. Summary of the Invention [Problem to be solved by the invention]
[0004] The present invention provides a lifting mechanism for the leg massage rollers of a massage chair, which can achieve smooth mechanism operation and a stable center of gravity, allowing for smoother massage of the soles of the feet. [Means for solving the problem]
[0005] The present invention provides a leg massage roller lifting structure for a massage chair, which includes a leg massage machine and a chair, the leg massage machine has a fixed base, the fixed base is connected to the bottom of the chair, a power source unit and a pivot base are provided on the fixed base, a rotating frame is provided on the bottom of the massage machine, a massage motor is provided in the massage machine, and massage rollers rotate on the left and right of the massage motor, respectively, the rotating frame is pivotally connected to the pivot base, a power motor is provided in the power source unit, and the power The rocker arms rotate to the left and right of the motor, and the rocker arms are pivotally connected to push rods, which are pivotally connected to the rotating frame. When using the chair, the user sits on the chair and leans the soles of their feet against the massage rollers. When the power motor moves and rotates the rocker arms, the rocker arms link with the push rods to perform mechanical operations, pushing and pulling the rotating frame, thereby causing the massager to repeatedly rock back and forth, and the massage rollers knead the soles of the feet, providing a massage effect.

[0011] In order to better understand and appreciate the objects, features, and advantages of the present invention, the following detailed description will be made with reference to the drawings in which: BRIEF DESCRIPTION OF THE DRAWINGS
[0012] First, as shown in Figures 1 to 3, the present invention provides a leg massage roller lifting structure for a massage chair, which includes a leg massager (10) and a chair (20). The leg massager (10) has a fixed base (11), which is connected to the bottom of the chair (20). A power source unit (12) and a pivot base (13) are mounted on the fixed base (11). A massager (14) has a rotating frame (141) mounted on the bottom. A massage motor (142) is mounted in the massager (14). Massage rollers (143) rotate to the left and right of the massage motor (142). The rotating frame (141) is pivotally connected to the pivot base (13). A power motor (121) is mounted in the power source unit (12). The rocker arms (15) are provided on the left and right sides of the power motor (121), and rotate on the left and right sides of the power motor (121). The rocker arms (15) are pivotally connected to the push rods (16), and the push rods (16) are pivotally connected to the rotating frame (141). As shown in Figures 4 to 6, when a user sits on the chair (20), he or she leans the soles of his or her feet against the massage rollers (143). When the power motor (121) moves and rotates the rocker arms (15), the rocker arms (15) interlock with the push rods (16) to operate the mechanism, pushing and pulling the rotating frame (141), which causes the massage device (14) to repeatedly rock back and forth, and the massage rollers (143) knead the soles of the feet, thereby providing a massage effect.
[0013] According to the above structure, the power source part (12) is fixed to the fixed base (11), and the massager (14) is pivotally connected to the pivot base (13), which distributes the weight and stabilizes the center of gravity. The power motor (121) pushes and pulls the massager (14) and swings it back and forth repeatedly, making the mechanism operation more stable and less susceptible to influences. When the user sits on the chair (20), the center of gravity of the leg massager (10) is further stabilized, which improves the stability of the leg massager (10) when it is in use.
[0014] Continuing with FIG. 4 to FIG. 6, which are schematic diagrams showing the mechanism operation when the present invention is actually used, the massager (14) is in the initial position, and when the power motor (121) moves and interlocks the rocker arm (15), the rocker arm (15) rotates and pushes the push rod (16), which further pushes the rotating frame (141), thereby pivoting the massager (14) and pushing it forward. After that, when the rocker arm (15) rotates and pulls the push rod (16), the push rod (16) pulls the rotating frame (141), causing the massager (14) to pivot and pull back. The flow of the pivot rotation of the massager (14) matches the shape of the legs that naturally hang down when the body is sitting, and the repeated up and down movements of the massage rollers (143) can massage the soles of the feet evenly.
[0015] The power source unit (12) is fixed to the fixed base (11), and the massager (14) is pivotally connected to the pivot base (13). This allows the power motor (121) to work in conjunction 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 more stable. Even if the weight of the massager (14) increases, it will not affect the operation of the leg massager (10).
[0016] As shown in Figure 7, this is another embodiment of the present invention, which provides a leg massage roller lifting structure for a massage chair. The leg massager (10) has only the massager (14) protruding in front of the chair (20), and the rest of the leg massager (10) is installed under the chair (20), so that the user's hair or trousers can be prevented from getting caught in the mechanism of the leg massager (10), which can cause danger.
[0017] As shown in FIG. 8, in yet another embodiment of the present invention, the present invention provides a leg massage roller lifting structure for a massage chair, and the chair (20) is a folding chair.
[0018] The above is merely one embodiment of the present invention and is not intended to limit the scope of the present invention, and all changes and modifications made within the scope of the claims of the present invention are also within the scope of the present invention.
