2. Description of the Related Art
Referring to
FIG. 1
, a conventional cabinet is shown to include upper and lower drawers
11
mounted slidably in a cabinet body
10
. The cabinet body
10
has upper and lower horizontal bars
12
provided at a front end thereof for limiting extension of the upper and lower drawers
11
from the front end of the cabinet body
10
. Each of the drawers
11

projects relative to a bottom side
111
of the drawer
11
, and abuts against the corresponding horizontal bar
12
when the drawer
11
is pulled forwardly relative to the cabinet body
10
to an extended position.
When it is desired to remove the drawer
11
from the cabinet body
10
, the drawer
11
is first moved to the extended position, and is then tilted to raise its rear end portion so as to enable the stop member
14

SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a cabinet assembly with a slidable drawer and a drawer limiting device which can ensure controlled removal of the drawer from a cabinet body.
According to a first aspect of the present invention, a cabinet assembly includes a cabinet body, a drawer, and a drawer limiting device. The cabinet body has an open front end, a rear end, a horizontal support rod extending between the front and rear ends, and a horizontal bar disposed adjacent to the front end and extending transverse to the support rod. The drawer is mounted slidably in the cabinet body, and is slidable forwardly and rearwardly along the support rod so as to be movable between an extended position, in which the drawer is extended from the front end of the cabinet body, and a retracted position, in which the drawer is retracted into the cabinet body. The horizontal bar on the cabinet body is disposed below the drawer. The drawer has a lower end and a rear end portion. The drawer limiting device is mounted on the rear end portion of the drawer, and includes a mounting plate fastened to the drawer, and a resilient limiting member which has a head portion secured to the mounting plate and a tail portion extending rearwardly from the head portion. The tail portion of the limiting member has an abutment section adjacent to the head portion and projecting downwardly relative to the lower end of the drawer. The abutment section abuts against the horizontal bar to limit forward extension of the drawer relative to the cabinet body when the drawer is moved to the extended position. The tail portion of the limiting member is deformable and is pushed upwardly by the horizontal bar by virtue of resiliency of the limiting member when the drawer is further applied with a forward pulling force at the extended position such that the limiting member ceases to limit forward extension of the drawer, thereby permitting removal of the drawer from the cabinet body.
According to a second aspect of the present invention, a drawer limiting device is adapted for use in a cabinet assembly which includes a cabinet body with an open front end provided with a horizontal bar and a drawer mounted slidably in the cabinet body and disposed above the horizontal bar. The drawer is slidable in forward and rearward directions transverse to the horizontal bar for moving between an extended position, in which the drawer is extended from the front end of the cabinet body, and a retracted position, in which the drawer is retracted into the cabinet body. The drawer limiting device includes a mounting plate and a resilient limiting member. The mounting plate is adapted to be fastened to the drawer. The limiting member has a head portion secured to the mounting plate, and a tail portion extending rearwardly from the head portion. The tail portion of the limiting member has an abutment section adjacent to the head portion and adapted to project downwardly relative to a lower end of the drawer. The abutment section is adapted to abut against the horizontal bar so as to limit forward extension of the drawer relative to the cabinet body. The tail portion of the limiting member is deformable, and is adapted to be pushed upwardly by the horizontal bar by virtue of resiliency of the limiting member when the drawer is further applied with a pulling force at the extended position in the forward direction such that the limiting member ceases to limit forward extension of the drawer, thereby permitting removal of the drawer from the cabinet body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIG. 4
, the preferred embodiment of the cabinet assembly according to the present invention is shown to include a hollow cabinet body
20
, upper and lower drawers
21
mounted slidably in the cabinet body
20
, and drawer limiting devices
4
mounted respectively on the drawers
21
.
The cabinet body
20
has an open front end
201
, a rear end
202
, upper and lower horizontal support rods
23
extending in a front-to-rear direction between the front and rear ends
201
,
202
, and upper and lower horizontal bars
22
disposed adjacent to the front end
201
and extending transverse to the support rods
23
.
The drawers
21
are mounted in the cabinet body
20
, and are disposed on the support rods
23
, respectively. Each of the drawers
21
is slidable along a respective one of the support rods
23
in forward and rearward directions.
Referring to
FIG. 2
, each of the drawers
21
has a slide rail
24
secured to a bottom side
211
thereof. The slide rail
24
extends in the front-to-rear direction transverse to the corresponding horizontal bar
22
, and is formed with a downwardly opening slide groove
243
, which extends along the length of the slide rail
24
. The slide groove
243
is formed as a dovetail groove, and engages slidably a respective one of the support rods
23
to enable sliding movement of the drawers
21
along the support rods
23
, respectively. Each of the horizontal bars
22
of the cabinet body
20
is disposed immediately below a lower end
215
of a respective one of the drawers
21
.
Referring to
FIGS. 2
to
4
, each of the drawer limiting devices
4
is mounted on a lateral side surface
242
of the slide rail
24
of a respective one of the drawers
21
, and is disposed at a rear end portion of the respective drawer
21
. Each of the drawer limiting device
4
includes an L-shaped mounting plate
30
with an upright plate portion
33
fastened or adhered to the lateral side surface
242
of the slide rail
24
of the respective drawer
24
, and a horizontal plate portion
31
disposed adjacent to a bottom surface
244
of the slide rail
24
. The upright plate portion
33
is provided with vertically spaced apart markers
32
.
Each of the drawer limiting device
4
further includes a limiting member
40
which is formed integrally from a resilient material of a relatively high strength, such as plastic steel. The limiting member
40
has a head portion
41
secured to the upright plate portion
33
of the mounting plate
30
, and a tail portion
42
extending rearwardly from the head portion
41
. The tail portion
42
has an abutment section
422
adjacent to the head portion
41
, a distal end
43
opposite to the head portion
41
, and a retaining section
44
between the abutment section
422
and the distal end
43
. The abutment section
422
extends downwardly and rearwardly from the head portion
41
along a curved path, and projects downwardly relative to the lower end
215
of the respective drawer
21
. The abutment section
422
defines a convex abutment face
421
that faces forwardly. The retaining section
44
extends rearwardly from the abutment section
422
, and has a curved configuration that defines a downwardly opening retaining groove
441
. The distal end
43
turns upwardly from the retaining section
44
.
In use, each of the drawers
21
is operable to slide between an extended position, in which the drawer
21
is extended from the front end
201
of the cabinet body
20
, such as the state of the lower drawer
21
shown in
FIG. 4
, and a retracted position, in which the drawer
21
is retracted into the cabinet body
20
, such as the state of the upper drawer
21
shown in FIG.
4
. At the extended position, the abutment face
421
on the abutment section
422
of the limiting member
40
abuts against an upper rear edge of the horizontal bar
22
to resist further sliding movement of the drawer
21
in the forward direction away from the cabinet body
20
.
Referring to
FIG. 5
, when the drawer
21
is further applied with a greater pulling force in the forward direction while it is at the extended position, the abutment section
422
will deform and will be pushed upwardly by the upper rear edge of the horizontal bar
22
so as to move past the same by virtue of the resiliency of the limiting member
40
. The upper rear edge of the horizontal bar
22
then engages the retaining groove
441
in the retaining section
44
, such as the state of the upper drawer
21
shown in FIG.
5
. The resiliency and the deformation of the abutment section
422
provide a buffering effect to retard forward sliding movement of the drawer
21
once the latter reaches the extended position. When the horizontal bar
22
engages the retaining groove
441
, the drawer limiting device
4
applies a resisting force to once again limit further sliding movement of the drawer
21
in the forward direction. Under this state, when the drawer
21
is continued to be pulled in the forward direction, the retaining section
44
would be pushed upwardly by the horizontal bar
22
and thus ceases to hinder forward sliding movement of the drawer
21
, such as the state of the lower drawer
21
shown in
FIG. 5
, thereby permitting removal of the drawer
21
from the cabinet body
20
.
Referring to
FIG. 6
, during fastening of the mounting plate
30
to the slide rail
24
of the drawer
21
, the position of the mounting plate
30
can be adjusted by aligning a selected one of the markers
32
with the bottom surface
244
of the slide rail
24
so as to ensure that the abutment section
422
of the limiting member
44
is disposed at a level lower than the lower end
215
(see
FIG. 2
) of the drawer
21
. This allows the drawer limiting device
4
to be adapted for use with drawers of different sizes.
Therefore, with the provision of the resilient limiting member
40
, the drawer limiting device
4
can limit extension of the drawer
21
, and can also buffer the fast sliding movement of the drawer
21
during the drawer removal operation when the drawer
21
reaches the extended position. As there is no need for tilting the drawer
21
, the drawer limiting device
4
thus provides added convenience when the drawer
21
is to be removed.
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment 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.
