Abstract
A telescoping slide assembly includes interconnected load-carrying, intermediate, and stationary slides. A retainer is used to retain a piece of equipment in a fixed position on the load-carrying slide.
Claims31
A telescoping slide assembly comprising
- interconnected load-carrying, intermediate, and stationary slides movable relative to one another to extend and retract the load-carrying and intermediate slides relative to the stationary slide, the load-carrying slide being formed to include a keyhole-shaped slot providing an enlarged-diameter entry and exit portion and a narrow-width post-retainer portion, the keyhole-shaped slot being adapted to receive a mounting post coupled to a piece of equipment to be carried on the load-carrying slide, and
- a post retainer including a base coupled to the load-carrying slide and an arm formed to include a retention aperture and being coupled to the base to move relative to the load-carrying slide between a slot-opening position lying away from the load-carrying slide to allow movement of the mounting post into the enlarged-diameter entry and exit portion of the keyhole-shaped slot and a slot-closing position receiving the mounting post in the retention aperture upon movement of the mounting post from the enlarged-diameter entry and exit portion into the narrow-width post-retainer portion of the keyhole-shaped slot.
A telescoping slide assembly comprising
- interconnected load-carrying, intermediate, and stationary slides movable relative to one another to extend and retract the load-carrying and intermediate slides relative to the stationary slide, the load-carrying slide having a generally flat wall and being formed to include a slot surrounded in the plane of the wall by the generally flat wall, and
- a post retainer coupled to the load-carrying slide and formed to include a retention aperture adapted to receive a mounting post coupled to a piece of equipment to be carried on the load-carrying slide and arranged to extend through the slot formed in the load-carrying slide, the post retainer being movable relative to the load-carrying slide between a slot-closing position adapted to retain at the same time the mounting post in the slot and the retention aperture and a slot-opening position adapted to release the mounting post from the slot and the retention aperture.
A telescoping slide assembly comprising
- interconnected load-carrying, intermediate, and stationary slides movable relative to one another to extend and retract the load-carrying and intermediate slides relative to the stationary slide, the load-carrying slide being formed to include a slot,
- a post retainer coupled to the load-carrying slide and formed to include a retention aperture adapted to receive a mounting post coupled to a piece of equipment to be carried on the load-carrying slide and arranged to extend through the slot formed in the load-carrying slide, the post retainer being movable relative to the load-carrying slide between a slot-closing position adapted to retain at the same time the mounting post in the slot and the retention aperture and a slot-opening position adapted to release the mounting post from the slot and the retention aperture, and
- wherein the post retainer further includes a distal end formed to include a lift tab arranged to extend at an angle relative to the base in a direction toward the intermediate slide upon movement of the load-carrying and intermediate slides to a retracted position within the stationary slide.
A telescoping slide assembly comprising
- interconnected load-carrying, intermediate, and stationary slides movable relative to one another to extend and retract the load-carrying and intermediate slides relative to the stationary slide, the load-carrying slide being formed to include a slot,
- a post retainer coupled to the load-carrying slide and formed to include a retention aperture adapted to receive a mounting post coupled to a piece of equipment to be carried on the load-carrying slide and arranged to extend through the slot formed in the load-carrying slide, the post retainer being movable relative to the load-carrying slide between a slot-closing position adapted to retain at the same time the mounting post in the slot and the retention aperture and a slot-opening position adapted to release the mounting post from the slot and the retention aperture, and
- wherein the post retainer includes, in series, a base, a body formed to include the retention aperture, an actuator arranged to intercept a mounting post moving into an entry and exit portion of the slot, and a lift tab arranged to extend at an angle relative to the body.
A telescoping slide assembly comprising
- interconnected load-carrying, intermediate, and stationary slides movable relative to one another to extend and retract the load-carrying and intermediate slides, a generally flat wall of the load-carrying slide being formed to include forward and rearward slots, each slot being adapted to receive a mounting post coupled to a piece of equipment to be carried on the load-carrying slide, at least one of said slots being formed to permit the post only to enter the slot by moving generally perpendicular to the plane of the generally flat wall, and
- a post retainer including a body formed to include a retention aperture and a base coupled to the post retainer and to the load-carrying slide, the body being arranged to move relative to the base from a slot-closing position blocking exit of a mounting post located in the rearward slot and in the retention aperture from the rearward slot to a slot-opening position allowing movement of a mounting post into and out of the rearward slot.
