CABINET WITH A ROLL DOOR

Abstract

A cabinet includes two opposite sidewalls and a roll door apparatus. Each sidewall longitudinally defines a number of cutouts. The roll door apparatus includes a first pole rotatably mounted between tops of the sidewalls, a roll door reeled about the first pole. The roll door has a first end mounted to the pole, and a second end opposite to the first end. A fixing piece extends from the second end of the roll door. Opposite ends of the fixing piece are engaged in two of the cutouts of the sidewalls.

Description

BACKGROUND

1. Technical Field

The present disclosure relates to a cabinet.

2. Description of Related Art

Doors of cabinets are generally made of armor plates and mounted to the cabinets with screws, which can be difficult and time-consuming because the doors are heavy. Furthermore, in opening a cabinet, the door of the cabinet is generally rotated about one of the sidewalls of the cabinet. A space for the door rotation is needed, which requires additional space.

DETAILED DESCRIPTION

The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to FIGS. 1 and 2, an exemplary embodiment of a cabinet with a roll door includes a top wall 10, a bottom wall 20, two opposite sidewalls 30 perpendicularly connected between opposite sides of the top and bottom walls 10 and 20, a front board 50 perpendicularly connected between upper portions of front sides of the sidewalls 30, and a roll door apparatus 40.

A plate 32 perpendicularly extends from the front side of each sidewall 30 toward the other sidewall 30 and longitudinally defines a slide slot 320 from top to bottom and facing the other sidewall 30. Each plate 32 defines a plurality of cuneiform cutouts 324 (referring to FIG. 7) communicating with the corresponding slide slot 320 in a rear wall 322 bounding the slide slot 320. Each sidewall 30 defines two fixing holes (not shown) in tops of front and rear sides of the sidewall 30.

Referring to FIG. 3 to FIG. 5, the roll door apparatus 40 includes a first pole 44, a second pole 42, two clockwork springs 440, a resilient belt 460, and a roll door 46.

The clockwork springs 440 fitted about opposite ends of the first pole 44. The resilient belt 460 made of rubber or leather. Each clockwork spring 440 includes an inner end 444 mounted to the first pole 44, and an outer end 446 opposite to the inner end 444 and mounted to the top wall 10 or one of the sidewalls 30 to which a corresponding one of opposite ends of the first pole 44 is pivotably fixed.

Two pins 420 extend out from opposite ends of the second pole 42. Two pins 442 extend out from opposite ends of the first pole 44.

The roll door 46 includes a plurality of main pieces 462 each including two hooks 470a at a top end and a bottom end of the main piece 462, a plurality of C-shaped connection piece 464 each including two latches 472 at top and bottom ends of the connection piece 464, an M-shaped operation portion 466 forming two hooks 470b at a top and a bottom ends of the operation portion 466, and a C-shaped engaging portion 468 forming a hook 470c at a top end of the engaging portion 468. Each main piece 462 defines a plurality of vents 476. An engaging piece 474 extends toward the hook 470 from a bottom end of the engaging portion 468 opposite to the top end.

Referring to FIGS. 6 and 7, in assembly, the latches 472 of a first connection piece 464 are movably latched with one of the hooks 470a of a main piece 462 and one of the hooks 470b of the operation portion 466. The latches 472 of a second connection piece 464 are movably latched with the other hook 470b of the operation portion 466 and the hook 470c of the engaging portion 468. The latches 472 of each of the remaining connection pieces 464 are movably latched with two hooks 470a of two adjacent main pieces 462. Thereby, a connection piece 464 is connected between every two adjacent main pieces 462, and the roll door 46 capable of being reeled. The resilient belt 460 includes a first end fixed to the first pole 44. The resilient belt 460 is reeled about the first pole 44. A second end of the resilient belt 460 opposite to the first end is connected to a main piece 462 opposite to the engaging portion 468. The pins 442 are inserted into the front side fixing holes of the sidewalls 30, to pivotably mount the first pole 44 between tops of the front sides of the sidewalls 30. The pins 420 are inserted into the rear side fixing holes of the sidewalls 30, to pivotably mount the second pole 42 between tops of the rear sides of the sidewalls 30. The roll door 46 is reeled about the first pole 44, and is rounded about the second pole 42 from bottom to top. The roll door 46 passes a top of the first pole 44 and extends downward. Thereby, opposite sides of a distal end of the roll door 46 opposite to the resilient belt 460 are slidably received in the slide slots 320 of the sidewalls 30. Opposite sides of the engaging piece 474 are engaged in two topmost cutouts 324 of the sidewalls 30, to fix the roll door 46 to the sidewalls 30. The front board 50 covers the distal end of the roll door 46 (referring to FIG. 1).

In use, the engaging portion 468 is pulled away from the rear wall 322, to disengage the engaging piece 474 from the topmost cutouts 324. The operation portion 466 is then moved down toward the bottom wall 20, to pull down the roll door 46. The clockwork springs 440 and the resilient belt 460 are deformed. When the cabinet is needed to be partly closed, opposite ends of the engaging piece 474 are correspondingly engaged in two corresponding cutouts 220 to fix the roll door 46 in a certain height, such as a middle of the cabinet, as shown in FIG. 2. When the cabinet is needed to be closed completely, the engaging piece 474 is engaged in the lowest cutouts 324.

In opening the cabinet, the engaging portion 468 is pulled away from the rear wall 322, to disengage the engaging piece 474 from the cutouts 324. The operation portion 466 is then released, the clockwork springs 440 and the resilient belt 460 are restored, thereby, the roll door 46 are automatically reeled about the first pole 44.

In another embodiment, the second pole 42 may be omitted.

In another embodiment, the resilient belt 460 may be omitted.

In another embodiment, the clockwork springs 440 may be omitted.

In another embodiment, the resilient belt 460 and the second pole 42 may be omitted.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
