Abstract
This invention relates to a clamping and holding device and more particularly to a clamping and holding device which can be attached to articles such as patio chairs to mount a holder for umbrellas and the like in a variety of positions. The device provides a first clamping arm and a second clamping arm pivotally connected to one another to engage an article. A holder extending laterally from the first clamping arm is provided to hold a tray, umbrella or the like. The holder may be locked in a variety of positions. A cam, cam follower and locking member or nut and bolt system prevents the inadvertent opening of the clamping arms.
Claims16
A clamping and holding device comprising
- a first clamping arm;
- a second clamping arm pivotally connected to the first clamping arm for cooperation with the first clamping arm to engage an article upon which the clamping and holding device is to be mounted;
- a holder extending laterally from the first clamping arm, said holder having a first position permitting pivotal movement of the holder with respect to the first clamping arm and a second position in which the holder is locked to prevent pivotal movement of the holder with respect to the first clamping arm;
- locking means for selectively inhibiting pivotal movement of the first clamping arm with respect to the second clamping arm from a closed position, the locking means including a cam on the second clamping arm and a cam follower on the first clamping arm to cooperate with the cam to bias the second clamping arm to the closed position.
A clamping and holding device comprising
- a first clamping arm;
- a second clamping arm pivotally connected to the first clamping arm for cooperation with the first clamping arm to engage an article upon which the clamping and holding device is to be mounted;
- a holder extending laterally from the first clamping arm, said holder having a first position permitting pivotal movement of the holder with respect to the first clamping arm and a second position in which the holder is locked to prevent pivotal movement of the holder with respect to the first clamping arm;
- locking means for selectively inhibiting pivotal movement of the first clamping arm with respect to the second clamping arm from a closed position, the locking means including a nut and bolt extending through the first and second clamping arms, wherein the first clamping arm is provided with a channel to enable the bolt to pass through the first clamping arm in an arc as the second clamping arm is moved from the closed position.
A clamping and holding device comprising:
- a first clamping arm;
- a second clamping arm pivotally connected to the first clamping arm for cooperation with the first clamping arm to engage an article upon which the clamping and holding device is to be mounted;
- a holder extending laterally from the first clamping arm with a mounting portion, the mounting portion telescopically received in the first clamping arm, said holder having a first position permitting pivotal movement of the holder and a second position in which the holder is locked to prevent pivotal movement of the holder, the mounting portion also with a conically shaped surface with its narrow diameter close to the holder, a compression spring acting on the mounting portion normally to retain it in the second position extending laterally from the mounting portion and acting to urge a locking button against the conically shaped surface;
- a nut and a bolt extending through the first and second clamping arms when the second clamping arm is in the closed position for selectively inhibiting pivotal movement of the first clamping arm with respect to the second clamping arm from a closed position and where the first clamping arm is provided with a channel to enable the bolt to pass through the first clamping arm as the second clamping arm is moved from the closed position.
