Description

[Detailed Description of the Invention] The present invention relates to a door opening/closing storage device in which a door is attached to the opening surface of a cabinet so as to be openable and closable, and the door can be stored within the cabinet.

Conventionally, as shown in FIG. 1, a partition plate 3 parallel to a side plate 2 is provided inside a cabinet 1, and a door 4 provided at the front of the cabinet 1 so as to be openable and closable is housed between the side plate 2 and the partition plate 3. It is known that this was done.

However, conventionally, in this type of door storage device, a telescopic moving member 5 as shown in FIG. Since it is designed to be attached freely, even when the movable member 5 is retracted to its maximum extent and the door 4 is retracted to the farthest point, the movable member 5 itself has a considerable thickness in the front and rear direction, so that the door 4 cannot be completely retracted. There was a problem in that the depth of the cabinet 1 had to be considerably increased.

The present invention provides a door opening/closing storage device that solves these conventional problems.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 9.

In the figure, 3 is the same partition plate as mentioned above, 4 is a door made of glass or the like, 7 is a stay, 8, 8 is a hinge for rotatably attaching the rear end of the door 4 to the stay 7, 9, 9 is a guide roller, 10.10' is a locking pin, and 11 is a fall prevention arm 13 rotatably connected to the stay 7 by a pin 12.
14 is a moving roller provided at the tip of the arm 11; 14 is a connecting arm whose one end is rotatably pivotally connected to the anti-falling arm 11 by a pin 15; and whose other end has a locking portion 14a;
6 and 16 are door guide rollers attached to the upper and lower ends of the partition plate 3, 17 and 17 are rails provided on the upper and lower sides of the inner surface of the partition plate 3, and 18 and 18 are provided near the rear end of the rail 17 and 17. This is the roller guide plate.

Note that one surface of the rail 17 is horizontal, and the rear end of the other surface is curved toward the one surface along the curved surface of the roller guide plate 18.

Further, the pin 12 that pivotally connects the fall prevention arm 11 is the fifth pin.
As shown in the figure, the stay 7 is fixed to a retaining plate 19 through a long hole (not shown), and both sides of the retaining plate 19 are connected to angles 21 and 21 with screws 20° and 20. .

In the above configuration, as shown in FIG.
When the door 4 is inserted between 6 and 16, the guide rollers 9 and 9 are placed on the horizontal surface of the rail 17 and 17, and the movable roller 13 is placed along the lower surface of the upper rail 17, that is, the curved surface, the door 4 opens. It is attached to the side surface of the partition plate 3 as shown in FIG.

This is a state in which the door 4 is pulled out, and in this state, the door 4 is rotated around the hinge 8, so that the front surface of the cabinet can be opened and closed.

Next, from this state, when the door 4 is pushed in the direction of the arrow hole in FIG. When the curved portion and the roller guide plate 18 move upward along the curved portion, the fall prevention arm 11 moves upward according to the curved portion of the roller guide plate 18.
It rotates in the direction of arrow B in the figure.

When the door 4 is retracted to its deepest position, the fall prevention arm 11 rises along the stay 7 as shown in FIG. 8, and in this state, the door 4 is completely retracted.

On the other hand, when the door 4 is to be pulled out, it can be pulled out to the front of the cabinet through the steps shown in FIGS. 8, 7, and 6 in reverse order to the above.

In this embodiment, the stay 7 is provided with two locking pins 10 and 10' centered around the pin 12, so that the connecting arm 14 can engage with any of the locking pins as shown in FIG. Moreover, since the rails 17, 17 are provided symmetrically above and below the partition plate 4, the door 4 can be stored on either the left or right side of the cabinet.

Further, since the mounting position of the pin 12 of the anti-falling arm 11 can be freely changed by the holding plate 19, the screw 20, and the angle 21, variations in the mounting dimensions of each component can be easily accommodated.

In this way, the present invention provides a rotatable fall-prevention arm on the stay, and the arm is arranged along the stay when the door is stored all the way. Therefore, the longitudinal dimension of the door storage member can be adjusted. can be made significantly smaller, and the entire cabinet can be made smaller.

Claims (1)

[Scope of utility model registration request] In a door opening/closing storage device in which a partition plate is provided parallel to the side plate of the cabinet, and a door provided on the opening surface of the cabinet so as to be freely openable and closable is stored between the side plate and the partition plate, the rear end of the door is hinged. A fall prevention arm is rotatably attached to the stay through the stay, and has a guide roller on the stay and a moving roller at the tip, and is suspended between the stay and the fall prevention arm, so that the fall prevention arm can be freely moved at a predetermined angle. A connecting arm that rotates is provided, a rail having a horizontal upper surface and an upwardly curved lower surface is provided on the partition plate, and a guide roller provided on the stay is placed on the upper surface of the rail and moved. The moving roller provided on the fall prevention arm is moved along the lower surface of the rail, and the layer is rotated until the moving roller enters the curved part of the lower surface of the rail and the fall prevention arm is aligned with the stay. A door opening/closing storage device that is housed in the above-mentioned cabinet.
