Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a cabinet assembly with a slidable drawer and a drawer limiting device therefore, more particularly to a drawer limiting device which can ensure controlled removal of the drawer from a cabinet body.




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


has a rear end portion provided with a generally hemi-spherical stop member


14


, and is slidable along a respective support rod


13


that is provided in the cabinet body


10


and that extends in a front-to-rear direction transverse to the horizontal bars


12


. The stop member


14


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


to climb over the corresponding horizontal bar


12


, thereby permitting removal of the drawer


11


from the cabinet body


10


. However, the tilting operation for removing the drawer


11


is difficult to conduct, especially when heavy objects are received in the drawer


11


. In this case, the horizontal bar


12


and the stop member


14


are likely to be deformed or even damaged.




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.
