Abstract
An adjustable height tiltable footrest comprises a plate having an upper surface adapted to support the feet of a human user, a base for supporting the plate and having front and rear guide surfaces which are oblique with respect to each other. The plate has roller assemblies with rollers which rest on the guide surfaces to support the plate tiltably, and the roller assemblies snap into recesses formed on the underside of the plate so that the spacing between the roller assemblies can be adjusted to vary the overall height of the plate.
Claims11
An adjustable height, tiltable footrest comprising:
- a plate having upper and lower surfaces, the upper surface being adapted to support the feet of a human user;
- base means comprising track means with front and rear guide surfaces, the front guide surface being in non-parallel relationship to the rear guide surface;
- first support means on said plate for engaging, and moving on, the front guide surface, and second support means on said plate for engaging, and moving on, the rear guide surface;
- and
- means, on the plate, for mounting said first and second support means on the plate in any selected one of multiple, fixed, spaced, relationships to each other;
- said plate being free to tilt as the first and second support means move on said front and rear guide surfaces while being mounted on the plate in fixed relationship to each other;
- whereby concurrent movement of the first support means on the front guide surface, and the second support means on the rear guide surface, results in a change in the pitch of the and alteration of the spacing between the first and second support means adjusts the height of the plate.

An adjustable height, tiltable footrest comprising:
- a plate having first and second side edges, and an upper surface adapted to support the feet of a human user;
- base means for supporting the plate while permitting tilting movement thereof, the base means having a front guide surface, and a rear guide surface;
- first and second roller means, secured to the plate and spaced from each other, for supporting the plate on the guide surfaces, the first roller means resting on the front guide surface and the second roller means resting on the rear guide surface, and the front and rear guide surfaces being in non-parallel relationship to each other so that the plate can be tilted by movement of the roller means on the guide surfaces;
- and
- means on said plate for adjusting the spacing between the first and second roller means, whereby the height of the plate can be adjusted.
