Abstract
The present apparatus comprises a manually adjustable tilt control mechanism which permits adjustable control of the front to back tilt of a chair assembly on a support frame, including a chair assembly having a lowermost seat portion, a column and forwardly extending support arm, for supporting the chair seat portion, a pair of dissimilarly sized resilient blocks, disposed between the end of the support arm and the bottom side of the chair seat portion. The resilient blocks may be adjustably compressed or decompressed between the bottom of the seat portion and the support arm, to adjust the tiltability of the seat.
Claims16
A manually adjustable tilt control mechanism permitting adjustable control of the front to back tilt of a chair assembly on a support frame, comprising:
- a chair assembly having a lowermost seat portion;
- a column and forwardly extending support arm, for supporting the chair seat portion;
- a pair of commonly-controlled compressible, spaced-apart dissimilarly-sized resilient blocks each sandwiched between a top face plate and a lower face plate, and are disposed between the end of said support arm and the bottom side of said chair seat portion, which blocks have an adjustable threaded bolt means disposed therebetween, for commonly adjusting the compression or decompression of both of said blocks, to affect the tiltability of said chair seat.
A method of adjusting the tiltability of a chair seat, comprising the steps of:
- attaching a pair of differently sized spaced-apart resilient blocks to the lower side of said seat;
- arranging a support arm onto the lower side of said resilient blocks, to provide support for said chair seat;
- placing a compression adjustment means between said resilient blocks, so as to adjustably commonly compress or decompress each of said blocks;
- and
- adjusting said compression adjustment means, so as to tighten and squeeze each of said spaced apart blocks, to commonly reduce their further compressibility, and thus reduce the tiltability of said chair seat.
A manually adjustable tilt control mechanism permitting adjustable control of the front to back tilt of a chair assembly on a support frame, comprising:
- a chair assembly having a lowermost seat portion;
- a column and forwardly extending support arm, for supporting the chair seat portion;
- a pair of dissimilarly sized spaced-apart resilient blocks having a thin gap therebetween, said blocks being disposed between the end of said support arm and the bottom side of said chair seat portion, both of said blocks being commonly compressible by an adjustable compression member disposed in said gap therebetween, to affect the tiltability of said chair seat.
