Referring to FIG. 3, the first preferred embodiment of a storage device box according to this invention is shown to include a casing unit 1, a releasing unit 4, and a front cover 18.
The storage device box of this embodiment is applicable for installing removably a storage device, such as a disk drive, therein, in a manner that will be described hereinafter.
The casing unit 1 includes a casing 13 and a frame 14. The casing 13 of the casing unit 1 includes opposite left and right walls and opposite top and bottom walls that cooperatively define an accommodating space 130, and has front and rear ends 131, 132 that are opposite to each other in a longitudinal direction. The rear end 132 of the casing 13 of the casing unit 1 defines a rear opening 11 that is in spatial communication with the accommodating space 130. The frame 14 of the casing unit 1 is mounted on the front end 131 of the casing 13. In particular, the frame 14 is provided with a first latching unit 141 that engages and is fastened to the left and right walls of the casing 13. In this embodiment, the frame 14 of the casing unit 1 defines a front opening 10 that is in spatial communication with the accommodating space 130 in the casing 13.
The storage device box further includes a guide rail 16 disposed in the accommodating space 130 in the casing 13 of the casing unit 1, provided on the right wall of the casing 13 of the casing unit 1, and formed with a rail groove 160.
With further reference to FIG. 4, the releasing unit 4 extends movably into the accommodating space 130 in the casing 13 of the casing unit 1 through the front opening 10 in the frame 14 of the casing unit 1. In this embodiment, the releasing unit 4 includes a releasing member 41 and a pushing member 42. The releasing member 41 of the releasing unit 4 extends in a longitudinal direction, is received slidably in the rail groove 160 in the guide rail 16, and has opposite first and second ends 411, 412 that are respectively distal from and proximate to the rear opening 11 in the casing unit 1. The pushing member 42 of the releasing unit 4 is disposed in the accommodating space 130 in the casing 13 of the casing unit 1, is provided on the second end 412 of the releasing member 41, and extends in a direction transverse to the longitudinal direction. In this embodiment, the pushing member 42 has a protruding portion 421 that protrudes toward the front opening 10 in the frame 14 of the casing unit 1.
The releasing unit 4 is movable relative to the casing unit 1 in the longitudinal direction between a first position, where the pushing member 42 is disposed distal from the front opening 10 in the frame 14 of the casing unit 1, and a second position, where the pushing member 42 is disposed proximate to (or at least more proximate to) the front opening 10 in the frame 14 of the casing unit 1.
The front cover 18 is coupled pivotably to the first end 411 of the releasing member 41 of the releasing unit 4 for covering and uncovering the front opening 10 in the frame 14 of the casing unit 1. In particular, the storage device box further includes a coupler 2 connected fixedly to the first end 411 of the releasing member 41 of the releasing unit 4. The front cover 18 is disposed externally of the casing unit 1, and has free end portion 181, and a pivot end portion 182 that is opposite to the free end portion 181 and that is connected pivotably to the coupler 2. In this embodiment, the front cover 18 is pivotable relative to the releasing member 41 of the releasing unit 4 between a closed position, where the front cover 18 covers the front opening 10 in the frame 14 of the casing unit 1, and an open position, where the front cover 18 uncovers the front opening 10 in the frame 14 of the casing unit 1.
It is noted that when the front cover 18 is disposed at the closed position, the front cover 18 extends in a direction transverse to the longitudinal direction. On the other hand, when the front cover 18 is disposed at the open position, the front cover 18 extends in the longitudinal direction and aligns with the releasing member 41 of the releasing unit 4.
In addition, the front cover 18 is co-movable with the releasing unit 4 relative to the casing unit 1 in the longitudinal direction. That is, the front cover 18 is movable in the longitudinal direction toward and away from the casing unit 1 so as to dispose the releasing unit 4 at the first and second positions, respectively.
The storage device box further includes a resilient padding 6 that is provided on the front cover 18, and that extends into the front opening 10 in the frame 14 of the casing unit 1 when the front cover 18 is disposed at the closed position.
The storage device box further includes a rear cover 15 that is mounted on the rear end 132 of the casing 13 of the casing unit 1 and that covers the rear opening 11 in the casing 13 of the casing unit 1. In particular, the rear cover 15 is provided with a second latching unit 151 that engages and is fastened to the left and right walls of the casing 13.
The storage device box further includes an electrical connector 3 mounted on the rear cover 15, and coupled electrically to a terminal (not shown) of a storage device 8 (see FIG. 5) when the storage device 8 is received in the accommodating space 130 in the casing 13 of the casing unit 1.
In use, when it is desired to install the storage device 8 in the casing unit 1, the storage device 8 is first partially inserted into the accommodating space 130 in the casing 13 through the front opening 10 in the frame 14. Then, the front cover 18 is moved from the open position to the closed position. During this operation, the resilient padding 6 pushes the entire storage device 8 into the accommodating space 130 in the casing 13 of the casing unit 1, as best shown in FIG. 5. Referring to FIGS. 6 and 7, when it is desired to remove the storage device 8 from casing unit 1, the front cover 18 is first moved from the closed position to the open position. During this operation, the pivot end portion 182 of the front cover 18 is brought to press against the frame 14 of the casing unit 1. This results in movement of the releasing unit 4 relative to the casing unit 1 in the longitudinal direction toward the second position, pushing of the storage device 8 by the pushing member 42, and disconnection of the terminal of the storage device 8 from the electrical connector 3, as best shown in FIG. 6. Thereafter, the front cover 18 is moved in the longitudinal direction away from the casing unit 1 so as to dispose the releasing unit 4 at the second position. During this operation, the pushing member 42 of the releasing unit 4 further pushes the storage device 8 such that the storage device 8 extends out of the casing unit 1 through the front opening 10 in the frame 14 of the casing unit 1, as best shown in FIG. 7.
The storage device box further includes a retaining unit 7 for retaining releasably the front cover 18 at the closed position. In this embodiment, the retaining unit 7 includes a movable member 71 that is provided on the free end portion 181 of the front cover 18, and a fixed member 72 that secures the movable member 71 on the free end portion 181 of the front cover 18. The movable member 71 is movable relative to the front cover 18 between a retaining position, where the movable member 71 engages the frame 14 of the casing unit 1, as best shown in FIG. 5, and a releasing position, where the movable member 71 is disengaged from the frame 14 of the casing unit 1.
The storage device box further includes a limiting unit for preventing movement of the releasing member 41 of the releasing unit 4 beyond the second position. In this embodiment, the limiting unit includes a first limiting member 52 that is disposed in the accommodating space 130 in the casing 13 of the casing unit 1 and that is provided on the releasing member 41 of the releasing unit 4, and a second limiting member 51 that is provided on the casing 13 of the casing unit 1 and that abut against the first limiting member 52 when the releasing member 41 of the releasing unit 4 is disposed at the second position. In this embodiment, the first limiting member 52 includes a recess-defining wall 521 that is formed on the releasing member 41 of the releasing unit 4 and that defines a recess 520. Further, in this embodiment, the second limiting member 51 includes a screw 511 that extends into the accommodating space 130 in the casing 13 of the casing unit 1 through the top wall of the casing 13 of the casing unit 1, and into the recess 520 in the releasing member 41 of the releasing unit 4. The construction as such permits the screw 511 of the second limiting member 51 to abut against the recess-defining wall 521 when the releasing unit 4 is disposed at the second position, thereby preventing the storage device 8 from dropping out of the storage device box of this embodiment before a user has a chance to grab onto the storage device 8. This also prevents the inadvertent removal of the releasing unit 4 from the casing unit 1.
The storage device box further includes a protective covering 17 that is provided on the top wall of the casing 13 of the casing unit 1. In this embodiment, the protective covering 17 is made from one of leather and metal.
FIG. 8 illustrates the second preferred embodiment of a storage device box according to this invention. When compared to the previous embodiment, the releasing unit 4 is dispensed with the pushing member 42 (see FIG. 3.
The releasing member 41 of the releasing unit 4 is formed with a plurality of holes 410 therethrough.
The releasing unit 4 further includes a plurality of fastening members 43, each of which extends through a respective one of the holes 410 in the releasing member 41 and engages threadedly the storage device 8, thereby fastening the storage device 8 to the releasing member 41. In this embodiment, each of the fastening members 43 is a screw.
The electrical connector 3 is provided on the second end 412 of the releasing member 41 of the releasing unit 4, and connects electrically to the terminal of the storage device 8 when the storage device 8 is fastened to the releasing member 41.
In use, when it is desired to install the storage device 8 in the casing unit 1, the storage device 8 is first fastened to the releasing member 41 of the releasing unit 4. Then, the releasing unit 4, together with the storage device 8, is inserted into the accommodating space 130 in the casing 13 of the casing unit 1 through the front opening 10 in the frame 14 of the casing unit 1. Thereafter, the front cover 18 is disposed at the closed position. On the other hand, when it is desired to remove the storage device 8 from the casing unit 1, the aforementioned operation is simply performed in a reverse order.
While the present invention has been described in connection with what are considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
