DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0027] Referring to FIGS. 5-20, reinforced server sliding rail mounting structures in accordance with the present invention are shown. The reinforced server sliding rail mounting structures shown in FIGS. 5-20 are intended for use with a server rack 95 and server 96, as shown in the view of the prior art device in FIG. 3. The first example reinforced server sliding rail mounting structure shown in FIGS. 5-18 includes an inner sliding rail 1, comprising a main rail wall 11 (see FIGS. 12-15) for connection to a server (not shown) and opposing upper and lower rail walls 12, 13 respectively and perpendicularly extended from opposing top and bottom sides of the main rail wall 11; an intermediate sliding rail 3, comprising a main rail wall 31 (see FIG. 15), an upper rail wall 32 and a lower rail wall 33 respectively and perpendicularly extended from opposing top and bottom sides of the main rail wall 31, inner ball grooves 321, 331 respectively longitudinally located on respective inner surfaces of the upper and lower rail walls 32, 33 and outer ball grooves 322, 332 respectively longitudinally located on respective opposing outer surfaces of the upper and lower rail walls 32, 33; a first ball bushing 2 slidably mounted between the inner sliding rail 1 and the intermediate sliding rail 3; an outer sliding rail 5, comprising a main rail wall 51 (see FIGS. 12, 13 and 15), upper and lower rail walls 52, 53 respectively and perpendicularly extended from opposing top and bottom sides of the main rail wall 51 and inner ball grooves 521, 531 respectively longitudinally located on respective inner surfaces of the upper and lower rail walls 52, 53; a second ball bushing 4 (see FIG. 12) slidably mounted between the intermediate sliding rail 3 and the outer sliding rail 5; and a front bracket 6 and a rear bracket 7 respectively fixedly fastened to opposing front and rear ends of the outer sliding rail 5 by fastening members 50 for mounting on an opposing front side 8 (see FIGS. 5, 9 and 11) and rear side (not shown) of a server rack, which front bracket 6 includes a bracket body 61 and upper and lower bracket walls 62, 63 respectively extended from opposing top and bottom sides of the bracket body 61.
[0028] Thus, the inner sliding rail 1 can be pulled outward while connected to the server (not shown) to carry the intermediate sliding rail 3 outward to an extended position (see FIGS. 5-8 and 12-15), or pushed inward with the server (not shown) to carry the intermediate sliding rail 3 to the inward position (see FIGS. 9 and 10). Since the act of moving a server sliding rail assembly inward or outward between an extended position and an inward position is known in the art, it will not be further detailed here.
[0029] The main features of the example reinforced server sliding rail mounting structures are outlined hereinafter.
[0030] The front bracket 6 further comprises an upper reinforcing rib 621 and a lower reinforcing rib 631 respectively mounted on the upper bracket wall 62 and the lower bracket wall 63 (see FIGS. 8 and 10). Thus, when the intermediate sliding rail 3 is moved outward into the front bracket 6 (see FIGS. 5-8, 12 and 14), the upper and lower reinforcing ribs 621, 631 are respectively engaged into the outer ball grooves 322, 332 of the intermediate sliding rail 3 to reinforce the structural strength of the intermediate sliding rail 3, and thus, when the server is moved outward with the inner sliding rail 1, the intermediate sliding rail 3 is well reinforced against deformation by the upper and lower reinforcing ribs 621, 631.
[0031] The front bracket 6 further comprises top and bottom reinforcing components 622, 632 (see FIGS. 10, 11 and 13) respectively mounted on respective rear ends of the upper and lower reinforcing ribs 621, 631 at the upper and lower bracket walls 62, 63 of the front bracket 6. The top and bottom reinforcing components 622, 632 each have a portion 6221, 6321 thereof adapted for engagement with the outer ball grooves 322, 332 (see FIG. 13) of the intermediate sliding rail 3 respectively, and an opposite portion 6222, 6322 thereof adapted for engagement with the inner ball grooves 521, 531 of the outer sliding rail 5 respectively. Thus, the top and bottom reinforcing components 622, 632 significantly reinforce the structural strength of the coupling area between the intermediate sliding rail 3 and the outer sliding rail 5, avoiding deformation of the server sliding rail assembly due to the heavy loading or human factors when in the extended position.
[0032] Further, the rear ends of the upper and lower reinforcing ribs 621, 631 of the upper and lower bracket walls 62, 63 of the front bracket 6 are respectively connected to the top and bottom reinforcing components 622, 632 (see FIGS. 11, 13 and 14), i.e., the upper reinforcing rib 621 and the upper reinforcing component 622 are integrally formed in one piece (for example, formed of zinc alloy integrally); the lower reinforcing rib 631 and the lower reinforcing component 632 are integrally formed in one piece (for example, formed of zinc alloy integrally). Alternatively, the upper and lower reinforcing ribs 621, 631 of the upper and lower bracket walls 62, 63 of the front bracket 6 can be kept apart from the top and bottom reinforcing components 622, 632 outer sliding rail 5 (see FIG. 16).
[0033] FIGS. 19-20 illustrate portions of another example of the present invention in the form of an alternative reinforced server sliding rail mounting structure for connection to a server rack and to a server. This alternative example is identical to the first example shown in FIGS. 5-18, other than with respect to the portions shown in FIGS. 19-20. Upon closer inspection, the upper reinforcing rib 621 of the upper bracket wall 62 of the front bracket 6 is integrally formed in one piece, and the lower reinforcing rib 631 of the lower bracket wall 63 of the front bracket 6 is integrally formed in one piece. The upper and lower reinforcing ribs 621, 631 engage the outer ball grooves 322, 332 respectively longitudinally located on respective opposing outer surfaces of the upper and lower rail walls 32, 33 of the intermediate sliding rail 3 to provide reinforcement when the reinforced server sliding rail mounting structure is extended outward to an outward position. The front bracket 6 also is shown as being connected to the outer sliding rail 5 by alternative fasteners, in the form of rivets 50.
[0034] In conclusion, the reinforced server sliding rail mounting structure in accordance with the present invention has advantages and features as follows.
[0035] An upper reinforcing rib 621 and a lower reinforcing rib 631 are respectively mounted on the upper bracket wall 62 and the lower bracket wall 63, so that when the intermediate sliding rail 3 is moved outward into the front bracket 6 (see FIGS. 5-8, 12, 14 and 19), the upper and lower reinforcing ribs 621, 631 are respectively engaged into the outer ball grooves 322, 332 of the intermediate sliding rail 3 to reinforce the structural strength of the intermediate sliding rail 3, and thus, when the server is moved outward with the inner sliding rail 1, the intermediate sliding rail 3 is well reinforced against deformation by the upper and lower reinforcing ribs 621, 631.
[0036] In the first example of FIGS. 5-18, top and bottom reinforcing components 622, 632 (see FIGS. 10, 11 and 13) are respectively mounted on respective rear ends of the upper and lower reinforcing ribs 621, 631 at the upper and lower bracket walls 62, 63 of the front bracket 6, wherein the top and bottom reinforcing components 622, 632 each have a portion 6221, 6321 thereof adapted for engagement with the outer ball grooves 322, 332 (see FIG. 13) of the intermediate sliding rail 3 respectively, and an opposite portion 6222, 6322 thereof adapted for engagement with the inner ball grooves 521, 531 of the outer sliding rail 5 respectively, and thus, the top and bottom reinforcing components 622, 632 significantly reinforce the structural strength of the coupling area between the intermediate sliding rail 3 and the outer sliding rail 5, avoiding deformation of the server sliding rail assembly due to heavy loading or human factors when in the extended position.
