Foldable leg rest
First Claim
1. A foldable leg rest comprising:
- a slide base including;
a slide frame having two sides and a front end; and
two supporting arms respectively slidably mounted on the sides of the slide frame and each supporting arm having;
a front end;
a projection extending from the front end of the supporting arm; and
a rolling bearing and a roller mounted on the projection;
a first folding assembly including;
a first frame having;
a front end;
a rear end pivotally connected to the front end of the slide frame; and
a bottom surface having two side portions; and
two guide pieces respectively secured to the side portions of the bottom surface of the first frame and each guide piece having a guide slot for allowing the projection of a corresponding supporting arm to extend therethrough and to move therealong;
a second folding assembly including a second frame having a rear end pivotally connected to the front end of the first frame;
a first stage drive mechanism mounted on the slide base and operated to drive the supporting arms to slide relative to the slide frame and to make the projections of the supporting arms move along the guide slots of the guide pieces so that the first frame is pivoted relative to the slide base; and
a second stage drive mechanism mounted on the first frame and operated to drive the second frame to pivot relative to the first frame.

Abstract
A foldable leg rest has a slide base, a first folding assembly, a second folding assembly, a first stage drive mechanism and a second stage drive mechanism. The slide base has a slide frame. The first folding assembly has a first frame pivotally connected to the slide frame. The second folding assembly has a second frame pivotally connected to the first frame. In use, the first stage drive mechanism is operated to drive the first frame to pivot relative to the slide frame and the second stage drive mechanism is operated to drive the second frame to pivot relative to the first frame. Therefore, the legs of a sitter can be stretched and placed on the folding assemblies so as to enhance comfort and minimize fatigue.
