CABINET HAVING THE BRAKE IN DRAWER "

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cabinet having a brake on a drawer portion, and more particularly, to a cabinet capable of controlling the sliding of a drawer portion by configuring a brake for controlling the rotation of the roller portion according to whether the handle portion is operated.

In general, a cabinet refers to a field for storing office documents or goods, and is an upright box made of metal or synthetic resin.

Such a cabinet is divided into a door type cabinet and a sliced type cabinet depending on the configuration of the door and the drawer.

A door-type cabinet consists of a main body divided into one or several spaces for storing articles and a door that can be opened or closed on one side or both sides.

A sliding cabinet is a cabinet which can open and close a plurality of drawers including a storage space by using sliding parts such as rails. The cabinet includes a longitudinal sliding cabinet in which a plurality of drawers are vertically arranged according to the aligning direction of a sliding drawer, And a lateral sliding cabinet in which the drawers are arranged to the left and right.

Of the above cabinets, the transverse sliding cabinet is provided with a rail so that the storage portion can slide, and the storage portion protrudes toward the front portion side along the rail. Therefore, the storage portion is exposed to the outside and is suitable for storing heavy objects.

Therefore, the transverse sliding cabinet must be able to easily open and close the cabinet door while preventing heavy bending of the drawer bottom plate caused by the load of the stored object.

A tool cabinet and / or a material cabinet is disclosed in European Patent Publication No. 1154879 in order to realize a more natural sliding operation while avoiding the tilting phenomenon due to the weight of the object stored in the drawer.

In the above-described configuration of the cabinet, one or more supports such as rollers, cylinder cylinders, or bearings may be provided at the front and rear portions of the plurality of vertical drawer bottoms so that the weight of the drawer is completely supported on the floor, And more particularly to a tool and / or article cabinet in which a drawer is opened and closed by providing a support portion at the front of the bottom surface and providing a drive trajectory for driving the drawer on the bottom surface of the main body.

FIG. 1 shows a conventional cabinet. As shown in the drawing, a plurality of vertical drawers 3 are provided with rollers 7 on the bottom surface thereof so that the drawer 3 can be opened and closed from the main body 2. At this time, since the roller 7 has a function of supporting not only the opening and closing but also the bottom surface of the drawer 3, the drawer 3 is opened and closed while maintaining the horizontal.

However, when the conventional cabinet is installed on a floor having a predetermined inclination, the drawer is forcibly closed or opened. That is, the drawer may be opened or closed in the inclined direction of the floor, thereby causing a safety accident, and the object stored in the drawer may fall and the object may be damaged. In order to solve this problem, it is possible to arrange the rollers by providing a support for restraining the rollers. However, it is very troublesome to install a support for each sliding position of the drawer.

In addition, even when the above-described conventional cabinet is installed on the floor which is kept horizontal, even if the user expects the unintended operation, for example, the drawer, the drawer is slid and closed, .

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cabinet in which a brake is provided in a drawer portion to solve the above problems. And a cabinet in which a brake is provided in a drawer part which can be released.

First, the configuration of the roller unit 400 will be described, and the brake unit 500 for controlling the rotation of the roller unit 400 will be described.

The roller unit 400 includes a roller case 410, bearings 420 and 421, a shaft 430, and rollers 440 and 441.

The roller case 410 is coupled to the coupling body 450 to be installed in the inner lower portion of the front plate 210 and has a through hole in which bearings 420 and 421 are installed in a pair of protruded brackets (411).

The bearings 420 and 421 are installed in the through holes 411 and a shaft 430 is provided between the bearings 420 and 421. Both ends of the shaft 430 are protruded from the bearings 420 and 421 do.

Rollers 440 and 441 are provided on the portions protruding from both sides of the bearings 420 and 421, respectively.

The shaft 430 is rotated by the rotation of the rollers 440 and 441 and the rotation is smoothly performed by the bearings 420 and 421 provided on the shaft 430 and the roller case 410. [

In the configuration of the roller unit 400, the brake unit 500 may be configured to intermittently rotate the shaft 430.

The brake portion 500 is configured to include a bracket 510, a disk 520, an operating piece 530, a bar 540, and a return spring 550.

The bracket 510 is coupled to the roller case 410 and the disc 520 is hinged to the bracket 510 to be rotatable at a certain range of angles.

The shaft 520 is positioned within the rotation range of the disk 520 so that the disk 520 contacts the shaft 430 (see FIG. 6). At this time, the disk 520 may be formed in an arc shape so as to enlarge an area in contact with the outer circumferential surface of the shaft 430, and may be formed in a bent shape as in the accompanying drawings.

Meanwhile, the operation piece 530 is installed on the handle 300 and is operated by the user holding the handle 300.

7, the operation piece 530 is hinged between the left cover 310 and the right cover 320 of the handle 300, and the operation member 530 is hinged between the left cover 310 and the right cover 320, And a flow pin (531) is provided in the part (530) to flow within a predetermined range.

The bar 540 is installed between the actuating piece 530 and the disc 520 and transmits the driving force of the actuating piece 530 to the disc 520. The bar 520 is rotated And tilted within a predetermined range. At this time, one side of the bar 540 coupled to the handle 300 is coupled to the moving pin 531, and a predetermined clearance is generated according to the hinge rotation of the operating piece 530, and the bar 540 is driven . The bar 540 has a bending portion depending on the position of the handle 300 and the disc 520.

It goes without saying that the bar 540 may be composed of a wire.

The return spring 550 returns the disc 520 to bring the disc 520 into contact with the shaft 430 so that the operating piece 530 driven by the handle 300 by the return of the disc 520 is also initialized Position.

At this time, the return spring 550 may be installed at any position capable of returning the driving of the bar 540.

That is, as shown in FIG. 6 of the accompanying drawings, a bar 540 is installed through a central portion of the return spring 550 so that the return spring 550 is installed on the outer side of the bar 540, Is supported on the disc 520 and the other end is supported by the roller case 410. Or may be installed in the disc 520 and the roller case 410, as shown in FIG. 6A of the accompanying drawings.

The return spring 550 in Fig. 6 is retracted by the action of the actuating piece 530 and the inflated force of the return spring 550 is actuated by frictional forces acting on the disc 520 and the shaft 430 in contact , The return spring 550 in Fig. 6A is inflated by the action of the operating piece 530 and the retracting force of the return spring 550 acts on the frictional force acting on the disc 520 and the shaft 430 in contact with each other do.

At this time, in order to further enhance the frictional force between the disc 520 and the shaft 430, a surface where the disc 520 and the shaft 430 are in contact with each other may further include a screw thread or a structure capable of increasing frictional force corresponding thereto.

However, even if the drawer unit 200 is installed on a predetermined inclined bottom surface, it may suffice that the drawer unit 200 is configured so as not to be pulled in or drawn out from an arbitrary position. For example, when the user pushes the front plate 210 of the drawer unit 200 without operating the operating member 530 of the handle 300 in a state where the drawer unit 200 is drawn out, The user can be impacted by the unexpected fixed state of the drawer unit 200 if the position of the drawer unit 200 does not change in that state.
