Fastening device for a securing data storage device

[0002] 1. Field of the Invention

[0003] The present invention relates to fastening devices, and more particularly to a fastening devices which readily and firmly secure computer data storage devices.

[0004] 2. Description of Related Art

[0005] Conventionally, a computer data storage device is directly secured to a bracket using screws. Installation and removal of screws requires a tool. This is unduly complicated and laborious, and reduces the efficiency of assembly in mass production facilities.

[0006] A common means to overcome the above shortcomings is to have a pair of slideways formed in a bottom portion of opposite side walls of the bracket. A sliding rail is then attached to each side of the data storage device. Thus, the data storage device can be readily slid into and secured to the bracket. Unfortunately, the sliding rails themselves are secured to the data storage device with screws. Thus use of the sliding rails does not significantly simplify the assembly procedure.

[0007] A common means for further simplifying assembly is to have a pair of plastic plates attached to opposite sides of the data storage device. The plates can secure the data storage device to a bracket without any tool. However, gaps are formed between the data storage device and the bracket. This results in increased risk of Electromagnetic Interference (EMI).

[0008] Examples of the abovementioned mechanisms are disclosed in Taiwan Patent Applications Nos. 81207129, 78201813, 79209891, 82207667, and 82202204; and U.S. Pat. Nos. 5,510,955 and 5,262,923.

[0009] Accordingly, an object of the present invention is to provide a fastening device which readily and firmly secures a data storage device.

[0010] A further object of the present invention is to provide a fastening device having simple structure,

[0011] In order to achieve the objects set out above, a fastening device of the present invention for securing a data storage device comprises a locating plate and a bracket. The bracket receives the data storage device therein, and the locating plate secures the data storage device to the bracket. The bracket includes first and second side panels. The first side panel defines a slot. The second side panel defines a groove for slidingly receiving a screw of the data storage device. The locating plate comprises an engaging section and an elastic section. The engaging section forms a latch stamped toward and received in the slot of the bracket, and engaged with the data storage device. The elastic section extends from the engaging section, and provides the locating plate with elastic deformation capability so that the latch can move in and out of the slot of the bracket.

[0012] Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0014] FIG. 2 is an exploded view of the fastening device of FIG. 1 fully assembled, together with a data storage device;

[0015] FIG. 3 is similar to FIG. 2, but showing the data storage device partly received in a bracket of the fastening device; and

[0016] FIG. 4 is similar to FIG. 3, but showing the data storage device completely received in the bracket and secured thereto by the fastening device.

[0017] Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.

[0018] Referring to FIGS. 1 and 2, a fastening device in accordance with the present invention comprises a locating plate 10 and a bracket 26. The fastening device secures a data storage device 50. The data storage device 50 defines a hole 54 in a side wall thereof, and a screw hole (not visible) in an opposite side wall thereof. A screw 52 is inserted in the screw hole of the data storage device 50.

[0019] The locating plate 10 of the fastening device is stamped from a metal plate. The locating plate 10 comprises an elongated central engaging section 12, an operating section 14, an arcuate elastic section 16 and a rectangular positioning section 18. A latch 22 is perpendicularly stamped from the engaging section 12 in a first direction. The latch 22 is disposed in the vicinity of one end of the engaging section 12. The operating section 14 is perpendicularly bent from an end of the engaging section 12 that is nearest the latch 22, in a second direction which is opposite to the first direction. The operating section 14 facilitates operation of the locating plate 10. A pair of reinforcing flanges 20 is bent from opposite longitudinal edges of the engaging section 12 respectively. The flanges 20 are bent to be oriented at obtuse angles relative to an outer face of the engaging section 12, and to be generally symmetrically opposite each other. An elongated guideway 24 is defined in the operating section 14. The elastic section 16 extends generally coplanarly from an end of the engaging section 12 which is opposite to the operating section 14. The elastic section 16 is arcuate, and provides the locating plate 10 with elastic deformation capability. The positioning section 18 extends generally coplanarly from a free end of the elastic section 16. A height of the positioning section 18 is greater than a height of the elastic section 16. The locating plate 10 is secured to the bracket 26 via the positioning section 18.

[0020] The bracket 26 comprises a bottom panel 28, and a pair of opposite first and second side panels 30, 40 extending vertically from the bottom panel 28. An L-shaped stopping tab 34 is outwardly stamped from a rear portion of the first side panel 30, for being received in the guideway 24 of the locating plate 10. A slot 32 is thereby defined in the first side panel 30 at the stopping tab 34. The slot 32 provides the latch 22 of the locating plate 10 with access to the hole 54 of the data storage device 50. The latch 22 can be moved in and out of the slot 32 due to elastic deformation of the elastic section 16. A pair of L-shaped hooks 36 is outwardly stamped from a middle portion of the first side panel 30. A blocking protrusion 38 is outwardly formed on the first side panel 30, forward of and generally between the hooks 36. The hooks 36 and blocking protrusion 38 cooperatively define a space (not labeled) therebetween for pressingly receiving the positioning section 18 of the locating plate 10. A horizontal groove 42 is defined in a middle of a front portion of the second side panel 40 of the bracket 26, for slidingly receiving the screw 52 secured to the data storage device 50. A plurality of support tabs 44 is inwardly and horizontally stamped from the first and second side panels 30, 40, for supporting the data storage device 50.

[0021] Referring to FIGS. 1-2, in assembly of the fastening device, the positioning section 18 of the locating plate 10 is pressingly received in the space between the hooks 36 and blocking protrusion 38. The hooks 36 clasp edge portions of the positioning section 18 at the elastic section 16, and the blocking protrusion 38 abuts against a free end of the positioning section 18. The latch 22 of the locating plate 10 is accommodated in the slot 32 of the bracket 26.

[0022] Referring to FIGS. 2-4, in use, the screw 52 is engaged in the screw hole (not visible) of the data storage device 50. The operating section 14 of the locating plate 10 is pulled outwardly, to cause the latch 22 of the locating plate 10 to exit the slot 32 of the bracket 26. With the latch 22 remaining outside the slot 32, the data storage device 50 is placed onto the support tabs 44 of the bracket 26. The data storage device 50 is then pushed into the bracket 26, with the screw 52 sliding in the groove 42. The data storage device 50 is pushed until the hole 54 thereof opposes the latch 22. The operating section 14 is then released to allow the locating plate 10 to resiliently return to its original position. In this process, the latch 22 is inserted into the hole 54 of the data storage device 50. The data storage device 50 is thereby readily and firmly secured to the bracket 26 by the locating plate 10.

[0023] During the above assembly procedure, the stopping tab 34 of the bracket 26 prevents the operating section 14 of the locating plate 10 from being pulled out too far. When the locking plate 14 is pulled out as far as is safely permissible, the stopping tab 34 engages with an end portion of the engaging section 12 remote from the elastic section 16 (see FIG. 3). Thus the elastic section 16 is protected from excessive deformation.

[0024] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
