Abstract
An example gas lift cylinder removal device described herein includes a collar assembly having a guide pin, a set screw, and a lead screw. The example cylinder removal device is disposed on a gas lift cylinder and provided proximate to and below a seat plate assembly of an example task chair. Operation of the gas lift cylinder removal tool from a first position to a second position provides a mechanical advantage to impart an upward force on a bushing of the seat plate assembly, thereby displacing the cylinder from the seat plate assembly. An example task chair having the gas lift cylinder removal tool is described herein comprising a support surface, a seat plate assembly, and a base assembly, the seat plate assembly including a bushing, an upper plate and a lower plate.
Claims20
An apparatus comprising:
- a collar assembly disposed beneath a surface;
- and
- a screw provided to move from a first position to a second position, a movement of
- the screw from the first position to the second position imparting mechanical displacement of the collar assembly from the surface.
A chair comprising:
- a seat plate;
- a gas lift cylinder coupled to the seat plate;
- and
- an apparatus disposed on the gas lift cylinder and beneath the seat plate, the apparatus comprising:
- a collar assembly;
- and
- a screw provided to move from a first position to a second position,
- wherein movement of the screw from the first position to the second position imparts mechanical displacement of the gas lift cylinder from the seat plate.
A method of removing a gas lift cylinder from a chair comprising:
- providing a chair comprising
- a seat plate,
- a gas lift cylinder being coupled to the seat plate, and
- an apparatus disposed on the gas lift cylinder and beneath the seat plate, the apparatus comprising
- a collar assembly, and
- a screw provided to move from a first position to a second position;
- and
- rotating the screw from the first position to the second position such that the screw makes contact with the seat plate urging the gas lift cylinder to uncouple from the seat plate.
