ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mounting device for mounting a peripheral device on a casing of an electronic apparatus, more particularly to one which facilitates installation and detachment operations of the peripheral device to and from the electronic apparatus.
2. Description of the Related Art
An electronic apparatus is typically installed with a peripheral device, such as a hard disk drive, a floppy disk drive, or a CD-ROM drive, which is connected electrically to a central processing unit (CPU) of the electronic apparatus for providing desired data storage and/or retrieval functions. Referring to
FIGS. 1 and 2
, conventionally, the peripheral device
12
is mounted within a casing
11
of the electronic apparatus using a mounting unit
13
which includes a pair of L-shaped mounting plates
131
, and a plurality of screw fasteners
132
,
133
. The casing
11
includes a horizontal base wall
111
, and a rectangular surrounding wall
112
which extends upwardly from the base wall
111
and which is formed with a horizontal top flange
113
that extends horizontally toward an interior of the casing
11
. Each of the mounting plates
131
includes a vertical plate portion
135
for attaching to a respective outer side wall of the peripheral device
12
, and a horizontal plate portion
134
for attaching to the base wall
111
of the casing
11
. A first set of the screw fasteners
132
extends through the vertical plate portions
135
of the mounting plates
131
and into the outer side walls of the peripheral device
12
for fastening the mounting plates
131
to the peripheral device
12
. A second set of the screw fasteners
133
extends through the horizontal plate portions
134
of the mounting plates
131
and into the base wall
111
of the casing
11
for fastening the mounting plates
131
to the casing
11
, thereby mounting the peripheral device
12
on the base wall
111
. The peripheral device
12
is typically disposed adjacent to one side of the surrounding wall
112
. The casing
11
is mounted with a front cap
114
at the surrounding wall
112
to permit access to the peripheral device
12
. The top flange
113
of the surrounding wall
112
on said one side adjacent to the peripheral device
12
is formed with notches
115
to permit extension of a tool therethrough for operating the screw fasteners
133
.
Since the screw fasteners
132
,
133
are relatively small and need to be operated one at a time using the tool, installation and detachment of the peripheral device
12
to and from the electronic apparatus are labor and time consuming.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a mounting device which facilitates installation and detachment operations of a peripheral device to and from a casing of an electronic apparatus.
Accordingly, the mounting device of the present invention includes a parallel pair of upright mounting plates, and a pair of anchoring members. Each of the mounting plates has a lower edge adapted to be fixed to a base plate of the casing, and a mounting side which confronts the other one of the mounting plates and which is formed with a mounting recess with an open upper end. The mounting recess is defined by a pair of upright clamping walls which are opposite to each other and which extend transverse to a longitudinal direction of the mounting plate, and a connecting wall which extends parallel to the longitudinal direction of the mounting plate and which interconnects the clamping walls. Each of the anchoring members has an upright engaging wall with two opposite vertical edges, and a pair of wing portions extending transversely from the vertical edges of the engaging wall. The engaging wall is formed with an engaging projection which projects in a direction opposite to the wing portions and which is adapted to extend into and engage a respective one of two opposite outer side walls of the peripheral device. The anchoring members are inserted respectively into the mounting recesses via the open upper ends. Each of the wing portions of the anchoring members engages a respective one of the clamping walls in the mounting recesses of the mounting plates such that each of the anchoring members is clamped between the clamping walls of the mounting recess of the respective one of the mounting plates.
