ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an anti-rattle pad and to a chair control mechanism incorporating such a pad.
BACKGROUND OF THE INVENTION
To minimize manufacturing cost, it is desirable to minimize the complexity of chair control mechanisms. On the other hand, it is also desirable to provide chair control mechanisms which give a user an impression of quality. These two desirata may conflict which may result in a manufacturing compromise. Since chair control mechanisms are generally made of metal or hard plastic, one problem encountered by simplified mechanisms is rattle.
This invention seeks to provide a simple chair control mechanism incorporating a gas cylinder which avoids raffle of the gas cylinder lever.
SUMMARY OF THE INVENTION
A chair control mechanism has a gas cylinder with a valve control finger extending from one end overlain by an actuator. An annular resilient pad is mounted to this end of the gas cylinder surrounding the valve control finger and maintains a spacing between the valve control finger and actuator when the actuator is not in use to avoid rattle. To allow retrofitting of a pad to the chair control mechanism, the pad may comprise an adhesive layer covered by an annular release tape.
Therefore, according to the present invention, there is provided a pad, comprising: an annular disk fabricated of a resilient material having an adhesive layer on a face, which face extends from an annulus of said disk; and an annular release tape releasably adhered to said adhesive layer.
In another aspect, there is provided a chair control mechanism, comprising: a gas cylinder with a valve control finger extending from one end; a gas cylinder actuator disposed over said valve control finger; and an annular disk fabricated of a resilient material mounted on said one end of said cylinder surrounding said valve control finger and perpetually deformed into a compressed state by said gas cylinder actuator so that said disk perpetually urges said actuator away from said valve control finger.
