Abstract
The present disclosure relates to a torso of a support device. The torso may include an axle assembly including an axle block and an axle passing through the axle block. The torso may also include a pelvic block assembly that includes a first pelvic block and a second pelvic block overlapping with the first pelvic block, the axle passing through the first pelvic block and the second pelvic block. The torso also includes a spreader pin passing through a spreader pin hole of the pelvic block assembly, the spreader pin and spreader pin hole being configured to adjust an angle between the first pelvic block and the second pelvic block.
Claims20
An adjustable support device comprising:
- a torso comprising:
- an axle assembly including an axle block and an axle passing through the axle block;
- a pelvic block assembly comprising:
- a first pelvic block, the axle passing through the first pelvic block;
- and
- a second pelvic block overlapping with the first pelvic block and the axle passing through the second pelvic block;
- and
- a spreader pin passing through a spreader pin hole of the pelvic block assembly, the spreader pin hole and the spreader pin being configured to adjust an angle between the first pelvic block and the second pelvic block;
- a first telescopic leg coupled to the first pelvic block, the first telescopic leg comprising:
- a first tube;
- a second tube slidably disposed inside of the first tube, the second tube extendable from and retractable into the first tube;
- a third tube slidably disposed inside of the second tube, the third tube extendable from and retractable into the second tube;
- and
- an extension mechanism associated with the first tube, the second tube, and the third tube, the extension mechanism being configured to:
- allow extension of the second tube away from the first tube and away from the torso;
- lock the second tube with respect to the first tube to inhibit retraction of the second tube into the first tube and toward the torso;
- and
- unlock, in response to the third tube being at least partially retracted into the second tube toward the torso, the second tube with respect to the first tube to allow the second tube to be retracted into the first tube and toward the torso;
- and
- a second telescopic leg coupled to the second pelvic block.

A device comprising:
- a torso including:
- a connection block configured to be coupled to an object;
- an axle block connected to the connection block;
- and
- a pelvic block assembly connected to the axle block;
- a telescopic leg coupled to the pelvic block assembly via a hip block and comprising:
- a first tube having a first end coupled to the hip block and a second end opposite the first end;
- a second tube slidably disposed inside of the first tube at the second end of the first tube, the second tube extendable from and retractable into the first tube;
- a third tube slidably disposed inside of the second tube, the third tube extendable from and retractable into the second tube;
- and
- an extension mechanism associated with the first tube, the second tube, and the third tube, the extension mechanism being configured to:
- allow extension of the second tube away from the first tube and away from the torso;
- lock the second tube with respect to the first tube to inhibit retraction of the second tube into the first tube and toward the torso;
- and
- unlock, in response to the third tube being at least partially retracted into the second tube, the second tube with respect to the first tube to allow the second tube to be retracted into the first tube and toward the torso.
