Driving mechanism for a massage chair
First Claim
1. A driving mechanism for a massage chair, the massage chair comprising a primary frame and a massaging set, the primary frame having a vertical bidirectional screw rod, a passive member connected to the massaging set jacketed onto the bidirectional screw rod;
- the driving mechanism characterized in that;
the massaging set comprises an integration space on a side for accepting a driving motor, an active end of the driving motor having an engaging gear inserted through the integration space;
the bidirectional screw rod vertically disposed on the primary frame and adjacent to the driving motor, the bidirectional screw rod having a first sliding slot and a second sliding slot, each having a stroke opposite the other, and both upper and lower ends of each stroke of the first and second sliding slots respectively forming a connecting slot connecting to each other;
a passive member jacketed onto the bidirectional screw rod and providing an engaging member that engages with the first and second sliding slots of the bidirectional screw rod such that the passive member is capable of moving along the bidirectional screw rod, and the passive member is disposed in the integration space of the massaging set, a plurality of driving teeth and a plurality of engaging teeth respectively formed on an upper and lower end of the passive member, and the engaging teeth engaging with the driving motor via the engaging gear in the integration and the driving teeth of the passive member engage a transmission gear coupled to a first shaft.

Abstract
A driving mechanism for a massage chair, the massage chair has a primary frame and a massaging set, the primary frame having a vertical bidirectional screw rod, a passive member connected to the massaging set jacketed onto the bidirectional screw rod. The massaging set utilizes the driving motor to provide synchronized massage movements and vertical movements, and the massaging set engages with the passive member and the bidirectional screw rod such that when the massaging set reaches to the very top end or the very bottom end the bidirectional screw rod it directly changes its direction of movement without any sensor, which can reduce and simplify structural costs.
