The present invention relates to a leg massager and more particularly to an attachable leg massager for chair that features smooth and stable mechanical motion.
Referring to
However, the conventional leg massager has following disadvantages: the massaging member (80) is only supported by the crank (82) and the connecting rod (83), and the power source (81) is located in the massaging member (80) so as to raise the center of gravity of the structure. Thus, when the weight of the user's leg is applied to the massaging member (80), the power source (81) has to counteract gravity during operation, which may cause the crack (82) and the connecting rod (83) to fail in performing proper mechanical motion, and then result in the massaging member (80) moving unevenly and lowering the massage effect. Therefore, there remains a need for a new and improved design for an attachable leg massager for chair to overcome the problems presented above.
The present invention provides an attachable leg massager for chair comprising a leg massager and a chair. The leg massager has a fixed base which is connected to the bottom of the chair, and the fixed base comprises a power source and a pivot base. A massaging member has a pivot frame at the bottom thereof, and a massage motor is installed in the massaging member, and each of two lateral sides of the massage motor is connected to a massage wheel. The pivot frame is pivotally connected to the pivot base, and a power motor is installed in the power source. Each of two lateral sides of the power motor is connected to a rocker arm, and 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, the user sits on the chair and leans the inner sides of legs on the massage wheels. The power motor is adapted to drive and rotate the rocker arms, and the rocker arms drive the push-pull rods to push and pull the pivot frame, so that the massaging member swings back and forth, and the massage wheels press the inner sides of legs to achieve the massage effect.
In one embodiment, the leg massager has the massaging member protruding from the front side of the chair, and other portions are located under the chair.
In another embodiment, the chair is a folding chair.
Comparing with conventional leg massager, the present invention is advantageous because: (i) the power source is fixed on the fixed base, and the massaging member is pivotally connected on the pivot base, so that the weight of legs is distributed on the leg massager and the center of gravity of structure is more stable; and (ii) the power source is fixed on the fixed base, and the massaging member is pivotally installed on the pivot base, so that the power motor, together with the rocker arms and the push-pull rods, are adapted to push and pull and pivotally rotate the massaging member in a relatively horizontal direction, which also makes the movement of the mechanism more stable, even if heavy weight borne on the massaging member not affects the operation of the leg massager.
The detailed description set forth below is intended as a description of the presently exemplary device provided in accordance with aspects of the present invention and is not intended to represent the only forms in which the present invention may be prepared or utilized.

In order to further understand the goal, characteristics and effect of the present invention, a number of embodiments along with the drawings are illustrated as following:
Referring to
The power source (12) is fixed on the fixed base (11), and the massaging member (14) is pivotally connected on the pivot base (13), so that the weight of legs is distributed on the leg massager and the center of gravity of structure is more stable. Also, the mechanism movement is more stable when the power motor (121) pushes and pulls the massaging member (14) to swing back and forth, and when the user sits on the chair (20), the center of gravity of the leg massager (10) is configured to be further stabilized, so as to improve the stability of the leg massager (10) when used.
Referring to
The power source (12) is fixed on the fixed base (11), and the massaging member (14) is pivotally installed on the pivot base (13), so that the power motor (121), together with the rocker arms (15) and the push-pull rods (16), are adapted to push and pull and pivotally rotate the massaging member (14) in a relatively horizontal direction, which also makes the movement of the mechanism more stable, even if heavy weight borne on the massaging member (14) not affects the operation of the leg massager (10).
