Description
BACKGROUND

1. Technical Field

The present disclosure relates to a slide assembly for a server, a drawer, or the like.

2. Description of Related Art

Computer network systems include many separate computer units or servers mounted in a rack. Slide assemblies allow the servers to be pulled out from the rack for maintenance. Current devices and techniques to secure the slide assembly to the rack are complicated and require mounting installation tools. Some techniques involve loose hardware, such as screws and bolts that can be lost and inconvenient to keep track of. Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIGS. 1 and 2 illustrate two exploded views of an embodiment of a slide assembly. The slide assembly includes a first slide 10, a second slide 30, a third slide 50, and a locking member 40 attached to the first slide 10.

The first slide 10 is mounted to a rack column 100 for receiving servers, drawers, or the like. The first slide 10 defines a locking hole 11, two first slots 13, and an engaging hole 15. In the illustrated embodiment, the two first slots 13 are substantially parallel to each other and defined at opposite sides of the first locking hole 11. The first locking hole 11 is substantially trapezoidal, and the first engaging hole 15 is rectangular.

Referring to FIG. 3, the locking member 40 includes a body 41. The body 41 includes a first end portion 411 and a second end portion 412. In one embodiment, the first end portion 411 and the second end portion 412 are resilient and located at opposite ends of the body 41. A first locking tab 42 and two ridges 43 protrude from the first end portion 411, and an engaging tab 45 protrudes from the second end portion 412. Each of the two ridges 43 is arcuate. In the illustrated embodiment, the two ridges 43 are substantially parallel to each other and located at opposite sides of the first locking tab 42.

An outer side of the second slide 30 includes two fixing boards 33, and a depressed recess 35 defined between the two fixing boards 33. A web 31 is located on a bottom of the depressed recess 35. The web 31 is rectangular and extends along a latitude direction. A second locking tab 311 protrudes from the second slide 30 toward the first slide 10. A second engaging hole 315 is defined in the second slide 30. In the illustrated embodiment, the second engaging hole 315 is rectangular. Two second slots 313 (as shown in FIG. 2) are defined in the second slide 30 at opposite sides of the second locking tab 311.

FIGS. 4-7 illustrate four assembled states of the slide assembly. In assembly, the body 41 of the locking member 40 may be mounted to an outer side of the first slide 10 through fasteners (not shown). The first locking tab 42 is received through the locking hole 11, and each ridge 43 is received through a corresponding first slot 13. The engaging tab 45 is received through the first engaging hole 15. The second slide 30 is slidably mounted to a first groove defined in an inner side of the first slide 10. The third slide 50 is slidably mounted to a second groove defined in an inner side of the second slide 30 away from the first slide 10. The two ridges 43 are pressed out of the first slots 13 by the third slide 50, such that the first end portion 411 is raised from the outer surface of the first slide 10. The slide assembly is retracted in a retracted position, and the first slide 10, the second slide 30, and the third slide 30 are aligned side by side.

To extend the slide assembly, the second slide 30 and the third slide 50 are slid toward an extending direction. When the second locking tab 311 slides over the first locking tab 42, the engaging tab 45 extends to the second engaging hole 315 and abuts against a flange 316 to prevent the second slide 30 from sliding further. The third slide 50 is then slid toward the extending direction. When a back end of the third slide 50 moves away from the first locking tab 42 and the ridges 43, the ridges 43 are released and are received through the first slots 13 and the second slots 313, and the first locking tab 42 is received through the locking hole 11. The first locking tab 42 blocks the second locking tab 311 to prevent the second slide 30 from sliding toward a retracting direction, which is opposite to the extending direction. Thus, the second slide 30 and the third slide 50 are in an extended position and are fully extended relative to the first slide 10.

To retract the slide assembly, the third slide 50 is slid along the retracting direction from the extended position, until the third slide 50 presses the two ridges 43 out of the first slots 13 and the second slots 313. The first locking tab 42 is removed from the locking hole 11, such that the first locking tab 42 does not block the second locking tab 311. The second slide 30 is slid towards the retracted position. The second slide 30 presses and disengages the engaging tab 45 from the first engaging hole 15. Thus, the second slide 30 and the third slide 50 are retracted.

It is also understood, that even though numerous characteristics and advantages have been set forth in the foregoing description, together with details of the structures and functions, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
