Abstract
A slide rail assembly includes first to third rails and an engaging mechanism movably mounted on the second rail. The second rail is displaceable with respect to the first rail, and the third rail is displaceable with respect to the second rail. The three rails define a length when the second rail is displaced from a first to a second position in a first direction and the third rail, to a third position in the same direction, extending out of the second rail. Once the second rail is displaced from the second to a fourth position in a second direction, the length is reduced, and the second rail is kept at the fourth position by the engaging mechanism.
Claims14
A slide rail assembly, comprising:
- a first rail having a front end and a rear end;
- a second rail displaceable with respect to the first rail;
- a third rail displaceable with respect to the second rail, the third rail having a front end and a rear end;
- a first engaging mechanism movably mounted on the second rail;
- at least one stopping member arranged on the first rail and including a disengaging portion;
- and
- a second engaging mechanism movably mounted on the second rail, the third rail including a rear stop and being configured to push the second engaging mechanism via the rear stop and thereby displace the second rail from a first position in a first direction, and the disengaging portion of the at least one stopping member disengages the second engaging mechanism from the rear stop when the third rail is displaced to a predetermined position;
- wherein the rear end of the first rail and the front end of the third rail define a first length therebetween when the second rail is displaced from the first position to the second position with respect to the first rail in the first direction and the third rail is displaced to a third position with respect to the second rail in the first direction and therefore extends out of the second rail;
- wherein when the second rail is displaced from the second position to a fourth position in a second direction, the first length between the rear end of the first rail and the front end of the third rail is reduced to a second length, and the second rail is kept at the fourth position with respect to the first rail by the first engaging mechanism.

A slide rail assembly, comprising:
- a first rail having a front end and a rear end;
- a second rail displaceable with respect to the first rail;
- a third rail displaceable with respect to the second rail, the third rail having a front end and a rear end;
- a first engaging mechanism movably mounted on the second rail;
- a first working member mounted on the third rail and being displaceable between a first working position and a second working position by user operation;
- a stopping base arranged on the second rail and having a stopping portion, the first working member being in the first working position and pressed against a side of the stopping portion of the stopping base when the third rail is displaced to a predetermined position in a first direction, and the first working member being no longer pressed against the stopping portion of the stopping base when the first working member is displaced from the first working position to the second working position by user operation, thus allowing the third rail to be detached with respect to the second rail;
- and
- a switching member mounted on the third rail, wherein the switching member is displaceable between a first switching position and a second switching position by user operation, in which the switching member is not aligned with the stopping portion of the stopping base when in the first switching position but is aligned with the stopping portion of the stopping base when in the second switching position;
- wherein the rear end of the first rail and the front end of the third rail define a first length therebetween when the second rail is displaced from a first position to a second position with respect to the first rail in a the first direction and the third rail is displaced to a third position with respect to the second rail in the first direction and therefore extends out of the second rail;
- and
- wherein when the second rail is displaced from the second position to a fourth position in a second direction, the first length between the rear end of the first rail and the front end of the third rail is reduced to a second length, and the second rail is kept at the fourth position with respect to the first rail by the first engaging mechanism.

A slide rail assembly adapted for mounting an object to a rack, the slide rail assembly comprising:
- a first rail mountable on the rack, the first rail having a front end and a rear end;
- a second rail displaceable with respect to the first rail;
- a third rail displaceable with respect to the second rail, the third rail being configured to carry the object and having a front end and a rear end;
- a first stopping member arranged on the first rail;
- a first engaging mechanism movably mounted on the second rail;
- a first working member mounted on the third rail, the first working member being displaceable between a first working position and a second working position by user operation;
- a second stopping member arranged on the first rail and including a disengaging portion;
- and
- a second engaging mechanism movably mounted on the second rail, the third rail including a rear stop and being configured to push the second engaging mechanism via the rear stop and thereby displace the second rail from a first position in a first direction, and the disengaging portion of the second stopping member disengages the second engaging mechanism from the rear stop when the third rail is displaced to a predetermined position;
- wherein the rear end of the first rail and the front end of the third rail define a first length therebetween when the second rail is displaced from the first position to a second position with respect to the first rail in the first direction and the third rail is displaced to a third position with respect to the second rail in the first direction and therefore extends out of the second rail;
- wherein when the second rail is displaced from the second position to a fourth position in a second direction, the first length between the rear end of the first rail and the front end of the third rail is reduced to a second length, and the second rail is kept at the fourth position with respect to the first rail by the first engaging mechanism;
- wherein the third rail is detachable with respect to the second rail when the first working member is displaced from the first working position to the second working position by user operation.
9 more elements
A method for operating a slide rail assembly, comprising the steps of:
- providing a first rail;
- providing a second rail displaceable from a first position to a second position with respect to the first rail in a first direction;
- providing a third rail displaceable with respect to the second rail to a third position beyond the second position;
- providing a first working member displaceable between a first working position and a second working position by user operation, wherein when the first working member is in the first working position, the third rail is at the third position with respect to the second rail such that the first rail, the second rail, and the third rail define a first length;
- providing a first engaging mechanism such that, when the second rail is displaced from the second position to a fourth position with respect to the first rail in a second direction, the first engaging mechanism keeps the second rail at the fourth position with respect to the first rail, thereby reducing the first length to a second length;
- displacing the first working member from the first working position to the second working position by user operation when the second length prevails, so that the third rail is detachable with respect to the second rail;
- and
- providing a at least one stopping member arranged on the first rail and including a disengaging portion;
- and
- providing a second engaging mechanism movably mounted on the second rail, the third rail including a rear stop and being configured to push the second engaging mechanism via the rear stop and thereby displace the second rail from the first position in the first direction, and the disengaging portion of the at least one stopping member disengages the second engaging mechanism from the rear stop when the third rail is displaced to a predetermined position.
