Benefits of technology

[0009]Because plastic material is used to over-mold the fixation device in the above-mentioned footrest structure according to the present invention, the whole weight of a product gets lighter without sacrifice of strength and other engineering properties.
[0010]Furthermore, because the present invention uses the injection molding to manufacture the fixation device, and fix the ring frame and the fixation device together, the fixating device does not need to be welded or riveted to the ring frame. It simplifies the assembling process. The manufacture cost can be reduced.

Problems solved by technology

The conventional footrest of a one-legged stool is made of metal, so its weight is pretty heavy.
Because the fixation device is riveted or welded to the ring frame, it is expensive and time consuming.

Abstract

A footrest of a one-legged seating device includes a fixation device and a ring frame. The fixation device is integrally molded of plastic and includes a hub having a central hole and a plurality of spokes around the hub. The ring frame is a metal tube shaped into a ring. Using injection molding, the ring frame is wrapped by and fixed to circumferential ends of the spokes. A sleeve and a pressed sheet are provided between the central hole of the hub and a supporting post. A locking bolt is screwed into the fixation device. The locking bolt presses to the pressed sheet, the pressed sheet to the sleeve, and the sleeve to the supporting post. Therefore the footrest is fixed to the supporting post at a desired height.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an improved structure of a footrest of a one-legged seating device.[0003]2. The Prior Arts[0004]A one-legged stool usually provides a footrest at a proper height of the supporting post for the consideration of comfortable seating. When a user sits on the cushion, he / she can tread on the footrest to let his / her feet get relaxed.[0005]The footrest structure of the prior art comprises a metal ring frame and a fixation device. The fixation device includes a plurality of spokes and a hub to fix the ring frame in place. The spokes are arranged in radial directions, and the hub is provided at the center where the spokes meet. The hub has a central hole to fix the footrest on the supporting post. The ends of spokes are riveted or welded to the ring frame.SUMMARY OF THE INVENTION[0006]The conventional footrest of a one-legged stool is made of metal, so its weight is pretty heavy. Because the fixa...
