1. Field of the Invention
The present invention relates to an auxiliary folding device, and more particularly to an auxiliary folding device for a treadmill.
2. Description of Related Art
FIG. 1 is a perspective schematic view of an auxiliary folding device for a treadmill in accordance with the present invention;
FIG. 2 is an exploded perspective view of the auxiliary folding device for a treadmill in FIG. 1;
FIG. 3 is a side cross sectional view of the auxiliary folding device for a treadmill if FIG. 1;
Referring to the drawings and initially to FIGS. 1-3, an auxiliary folding device (3) for a treadmill in accordance with the present invention is adapted to be mounted between a main frame (1) and a platform (2) of the treadmill. The main frame (1) includes a first post (11) and a second post (12) opposite to each other. A first connecting rod (14) is provided to connect the first post and the second post (12) to form a U-shape. A first pivot seat (15) centrally extends from the first connecting rod (14) and a rack (13) upwardly extends from the main frame (1) opposite to the first connecting rod (14). The platform (2) is pivotally connected to the main frame (1) between the first post (11) and the second post (12). The platform (2) includes a second connecting rod (22) transversely secured on a bottom of the platform (2), and a second pivot seat (23) extending from the second connecting rod (22) and corresponding to the first pivot seat (15).
The auxiliary folding device (3) has two opposite ends respectively pivotally connected to the first pivot seat (15) and the second pivot seat (23). The auxiliary folding device (3) includes a first post (31) pivotally connected to the first pivot seat (15), a second post (32) received in the first post (31) and a locking device (33) mounted on an outer periphery of the first post (31).
A spreading post (311) is movably received in the first post (31) between the first post (31) and the second post (32). The spreading post (311) is capable to longitudinally extend from the first post (31). The second post (32) has a spreading rod (321) movably received therein. The spreading rod (321) is capable to longitudinally extend from the second post (32). The spreading post (311) is moved with the spreading rod (321). In the preferred embodiment of the present invention, the second post (32) is an air cylinder and the spreading rod (321) is the piston of the air cylinder.
