When the second rail 12 is pulled out relative to the first rail 10 to a extreme position, the second restriction portion 36 of the second rail 12 is against the first restriction portion 28 of the first rail 10 so that the second rail 12 can lead the first rail 10 to move toward a front end of the first bracket 16. Preferably, a third rail 38 is slidably connected to the second rail 12 such that the slide assembly can be further extended to a longer distance.
The support member 14 is located adjacent to the front end 22 of the first rail 10 and has an opening 40 and a stop portion 42. In detail, the support member 14 and the first rail 10 can be two individual parts which are connected to each other by way of riveting, threading or any known method, to let the support member 14 be located adjacent to the front end 22 of the first rail 10.
The first bracket 16 is slidably connected to the support member 14 and has an aperture 44 and a contact portion 46. The contact portion 46 is shaped corresponding to the stop portion 42 of the support member 14. As shown in FIG. 4A, when the support member 14 moves toward a rear end of the first bracket 16 and reaches a predetermined position (as shown in FIG. 4A), the contact portion 46 is against the stop portion 42 of the support member 14 so that the support member 14 is stopped.
The engaging member 18 is fixed to the first bracket 16 and has a resilient arm 48 and an engaging portion 50. The engaging portion 50 is connected to the resilient arm 48 and located corresponding to the aperture 44 of the first bracket 16. When the opening 40 of the support member 14 overlaps the aperture 44 of the first bracket 16, the engaging portion 50 of the engaging member 18 can be inserted into the opening 40 of the support member 14 by a force from the resilient arm 48 or be released from the opening 40 of the support member 14 by the release member 34 of the second rail 12. In detail, the engaging member 18 and the first bracket 16 can be two individual parts which are connected to each other by way of riveting, threading or any known method, to let the engaging member 18 be connected to the first bracket 16.
Referring to FIG. 3A, the stop portion 42 of the support member 14 is located on an edge of the opening 40 of the support member 14 so that when the engaging portion 50 of the engaging member 18 is inserted into the opening 40 of the support member 14, the engaging portion 50 is against the stop portion 42 and stuck in the opening 40 of the support member 14. Further referring to FIG. 3B, the engaging portion 50 extends from the resilient arm 48 and has a engaging face 52 which is perpendicular to the resilient arm 48 for engaging with the opening 40 of the support member 14. Moreover, a release slant 54 extends from an end of the engaging portion 50 toward the resilient arm 48 and faces the aperture 44 of the first bracket 16.
As shown in FIGS. 4A and 4B, preferably, the first bracket 16 has a sidewall 56 and an end plate 58 which is perpendicular to the sidewall 56. The sidewall 56 has the aperture 44 defined therein, and the contact portion 46 extends from the sidewall 56. That is, the aperture 44 and the contact portion 46 both are located on the side wall 56. An installation member 60 is connected to the end plate 58, and a movable connection member 62 is connected to the installation member 60. The connection member 62 has a connection portion 64 and a release portion 66.
The release portion 66 can be operated via an operation space 68 to move the connection portion 64. The sidewall 56 has a through hole 70 through which the release portion 66 extends. The support member 14 has a fixing portion 72. Specifically, the movable connection member 62 is pivotable relative to the installation member 60, the fixing portion 72 of the support member 14 has a notch 74 which is bounded by two stop walls 76, and when the notch 74 of the fixing portion 72 overlaps the operation space 68, the release portion 66 of the connection member 62 is inserted into the notch 74 and flanked by the stop walls 76, thereby restricting an operation of the release portion 66.
The second bracket 20 is slidably connected to the rear end 24 of the first rail 10. Specifically, the second bracket 20 has a side plate 78 which has a pair of bent portions 80, and a path 82 is bounded by the two bent portions 80 such that the rear end 24 of the first rail 10 can be inserted into the path 82 and slide relative to the second bracket 20.
FIG. 5 is a top view of the slide assembly, wherein the slide assembly is connected to a first post 92 of a rack 90 by the first bracket 16 and connected to a second post 94 of the rack 90 by the second bracket 20, and one side of a chassis 96 is positioned on the slide assembly.
FIGS. 6A and 6B are a perspective view and a top cross section view, respectively, of the slide assembly, wherein the slide assembly is in an extended status. In the extended status, the first rail 10 and the support member 14 are led by the second rail 12 to move toward the front end of the first bracket 16, and when the opening 40 of the support member 14 overlaps the aperture 44 of the first bracket 16, the engaging portion 50 of the engaging member 18 is inserted into the opening 40 of the support member 14 by a force from the resilient arm 48 and against the stop portion 42 of the support member 14 to be stuck in the opening 40; in more detail, the engaging face 52 of the engaging portion 50 is engaged with the opening 40 of the support member 14, and thus the support member 14 is positioned. In other words, the support member 14 can be positioned after sliding toward the front end of the first bracket 16 for a distance. Moreover, since the first rail 10 and the support member 14 are connected to move simultaneously, the first rail 10 also can be positioned after sliding, together with the support member 14, toward the front end of the first bracket 16 for a distance as shown in FIG. 7. The first rail 10 and the support member 14 can be moved from the predetermined position (as shown in FIG. 4A) to an extended position (as shown in FIG. 6A) such that the extended length of the slide assembly is adjustable to provide sufficient space for the installation of the chassis 96, which is installed on the rack 90 as shown in FIG. 5.
Furthermore, as shown in FIGS. 6A and 6B, when the support member 14 slides toward the front side of the first bracket 16 and is positioned at the extended position, the notch 74 of the fixing portion 72 of the support member 14 overlaps the operation space 68 such that the release portion 66 of the connection member 62 of the first bracket 16 is flanked by the two stop walls 76 of the fixing portion 72 and thus the operation of the release portion 66 is restricted, whereby ensuring that the connection portion 64 of the connection member 62 (in FIG. 4A) to be hooked to the first post 92 of the rack 90 to prevent the slide assembly from dropping from the rack 90 and to prevent the chassis 96 from dropping to the ground and damaged.
Further referring to FIG. 8, when the second rail 12 is retracted toward the rear end of the first bracket 16 to collapse the slide assembly, the release member 34 of the second rail 12 pushes the engaging portion 50 along the release slant 54, so that the engaging portion 50 of the engaging member 18 is released from the opening 40 of the support member 14, thereby, the support member 14 can move back to the predetermined position as shown in FIG. 4A.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
