The base 20 includes a bottom panel 25, a pair of side panels 21 extending perpendicularly upward from opposite side edges of the bottom panel 25, and a front panel 23 extending perpendicularly upward from a front edge of the bottom panel 25. The front panel 23 is lower than the side panels 21 in height. A pivot 211 is arranged on an inner side of each side panel 21, and a projection 213 is projected inwardly from the inner side of each side panel 21. A flange 27 is bent inward from a top edge of each side panel 21, and a pair of slots 271 is defined in the flange 27 corresponding to the tabs 117 of each sidewall 11. A pair of fasteners 70 such as screws is provided corresponding to the pivots 211. A pair of fixing holes 231 is defined in the front panel 23 corresponding to the spring screws 131 of the bracket 10.
Each connecting piece 30 is generally an elongate strip. Each connecting piece 30 defines an aperture 31 in a distal end thereof, corresponding to the protrusions 111, the aperture 31 includes an entrance portion 311 and a pivot portion 313 in communication with the entrance portion 311, the entrance portion 311 is dimensioned to allow a corresponding protrusion 111 extending therethrough, and the pivot portion 313 is dimensioned to prevent the corresponding protrusion 111 existing theretfrom. A pair of rivets 33 is formed on each connecting piece 30 adjacent the aperture 31. An elongate guideway 35 is defined in each connecting piece 30 corresponding to the projections 213, an entrance hole 351 is defined in communication with a first end of the guideway 35 adjacent the rivets 33, and a retaining hole 353 is defined in a proximal end of the connecting piece 30 in communication with a second end of the guideway 35. The retaining hole 353 is generally perpendicular to the guideway 35. The guideway 35 and the retaining hole 353 are dimensioned to prevent corresponding projection 213 from withdrawing therefrom.
A pair of fixing plates 50 is provided to attach the connecting pieces 30 to the bracket 10. Each fixing plate 50 defines a notch 51 in a distal first end thereof, corresponding to the pivot portion 313 of the aperture 31 of each connecting piece 30, and a pair of rivet holes 53 in a second end thereof, for receiving the rivets 33 of each connecting piece 30.
In assembly, the bracket 10 is rotatably attached to the base 20 via the pivots 211 of the side panels 21 extending through corresponding pivot holes 113 of the bracket 10, and the fasteners 70 are engaged in the pivots 211 for preventing the pivots 211 from withdrawing from the pivot holes 113.
Each fixing plate 50 is attached to corresponding connecting piece 30 with the rivets 33 engaging the rivet holes 53, the notch 51 of each fixing plate 50 overlaps the pivot portion 313 of the aperture 31 of the corresponding connecting piece 30, and the first end of the fixing plate 50 covers the entrance portion 311 of the aperture 31. Each assembled connecting piece 30 and fixing plate 50 is attached to corresponding side panel 21 of the base 20 by means of the projection 213 extending through the entrance hole 351 and relatively sliding in the guideway 35, the distal end of the connecting piece 30 is pressed toward the protrusion 111 of corresponding sidewall 11 of the bracket 10, the protrusion 111 extends through the entrance portion 311 of the aperture 31 of the connecting piece 30 and pushes the first end of the fixing plate 50 outwardly, the bracket 10 is rotated outwardly until the protrusion 111 enters the pivot portion 313 of the aperture 31, the fixing plate 50 is restored to cover the entrance portion 311, and the notch 51 engages the protrusion 111 to attach the assembled connecting piece 30 and fixing plate 50 to the bracket 10. Alternatively, each connecting piece 30 can be pivotally attached to corresponding side panel 21 of the base 20 directly via other fixing means such as screws.
In use, FIG. 2 shows the bracket 10 is fixed to the base 20. The bracket 10 is generally accommodated in the base 20 with the protrusions 111 of the bracket 10 and the pivots 211 and the projections 213 of the base 20 being substantially in alignment with one another, and a plurality of components 90 including, for example, motherboard, hard disc drives, etc. is fixed on the bottom panel 25 under the bracket 10. The tabs 117 of the bracket 10 are engaged in the slots 271 of the base 20 respectively. The spring screws 131 of the bracket 10 are engaged in the fixing holes 231 of the front panel 23 of the base 20.
To maintain the components 90 under the bracket 10, the spring screws 131 are disengaged from the front panel 23 of the base 20, the bracket 10 is rotated outwardly from inside the base 20 by the rings 133. The bracket 10 is rotated around a first fixed axis defined by the pivots 211 of the base 20. The connecting pieces 30 are stretched slantingly outwardly, and the projections 213 of the base 20 are relatively slid along the guideways 35 of the connecting pieces 30 respectively, until the projections 213 engage in the retaining holes 353 of the connecting pieces 30 respectively such that the bracket 10 is suspended over the base 20, while the distal ends of the connecting pieces 30 are rotated around a second fixed axis formed by the protrusions 111 of the bracket 10. The protrusions 111 of the bracket 10, and the pivots 211 and the projections 213 of the base 20 together form a triangular shape during the bracket 10 being rotating away from the base 20 around the first fixed axis. The components 90 in the base 20 are exposed to facilitate servicing thereof.
To close the bracket 10, the connecting pieces 30 are pulled by the proximal ends thereof to disengage the projections 213 from the retaining holes 353 of the connecting pieces 30 respectively. The bracket 10 is then rotated back toward the base 20 until the front wall 13 of the bracket 10 seats on the front panel 23 of the base 20. The tabs 117 of the bracket 10 are engaged in the slots 271 of the base 20 respectively. The spring screws 131 of the bracket 10 are engaged in the fixing holes 231 of the front panel 23 to fix the bracket 10 to the base 20.
As an alternative embodiment, the connecting pieces 30 can be reversely connected to the bracket 10 and the base 20. That is, the apertures 31 of the connecting pieces 30 are respectively engaged with the projections 213 of the base 20 respectively, and the guideways 35 of the connecting pieces 30 engage with the protrusions 111 of the bracket 10 respectively.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
