Description

[Detailed description of the invention] This invention relates to a door opening/closing storage device used when attaching doors to various types of cabinets, and allows a door that covers the front of the cabinet to be stored in the cabinet so that it can be opened and closed freely. be.

Conventionally, in racks for storing audio equipment, the first
As shown in Figures a and b, the rear end of the glass door 3 is rotatably attached to the front end of the cabinet 1 via a hinge 2 consisting of screws 2a, metal fittings 2b and 2C as shown in Figure 1. The front side of the cabinet 1 is opened and closed by a door 3.

However, in this case, when door 3 is opened, door 3 always opens.
protrudes from the front of the cabinet 1, making it difficult to put in and take out records from the shelves installed on the side of the cabinet 1, and also cause external force to be applied to the door 3 by mistake, damaging the hinge 2 and door 3. There was a problem with this.

To solve this problem, see Figure 2a.

As shown in b and c, a storage section 5 for the door 4 is provided on the bottom of the cabinet 1, a pin 4b provided on the door 4 is loosely fitted into a groove 6a provided on the side plate 6 of the cabinet 1, and a pin 4b provided on the side of the door 4 is provided. Groove 4
Loosely fit the pin 6b provided on the side plate 6 into the pin 4b.
, 6b are moved along the grooves 5a, 4a.

With this configuration, the door 4 can be rotated from the position shown by the broken line in FIG.

However, in this case, since the door 4 is stored at an angle, the height of the storage section 5 must be made considerably large, which causes the problem that the internal space of the cabinet 1 becomes small.

Furthermore, if a door that opens and closes in the vertical direction is made of glass, it will be very heavy and there is a risk that the door will be damaged during opening and closing operations, so it cannot be used in cabinets that use glass doors. There wasn't.

Also, by using the configuration shown in Figure 2, Figure 3 a, l)
As shown in FIG.
, 7b are provided, and the upper and lower ends of the glass door 7 are slidably inserted into the grooves 8a of the rotor 8 rotatably mounted on the top and bottom surfaces of the cabinet 1. It is also possible to store the door 7 by sliding it along grooves 9a and 9b provided on the upper and lower inner surfaces.

However, in this case, since the door 7 itself has a considerable weight, when the door 7 is opened, the door 7 tilts forward as shown by the broken line in Figure 3C, making it difficult to open and close the door 7 smoothly. The problem is that it cannot be done.

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

An embodiment of the present invention will be described below with reference to FIGS. 4 to 7.

In the figure, 10 is a cabinet, 10a is a side plate, 10
b is the bottom plate, 10C is the top plate, 10d is the back plate, 10e is the shelf board, 10f is the partition plate, 11 is the partition plate 10f and the side plate 10a
12 is a glass door, 13 is a guide rail attached to the front and back direction of the partition plate 10f, and 14 is four connecting arms 14a to 1 as shown in FIG.
4d, a cylindrical spacer 14e, a fixing screw 14f that serves as a fixed fulcrum, pins 14g and 14h that are inserted into the intersections of the connecting arms 14C and 14d and the through hole 15a of the door support plate 15 and serve as movable fulcrums; A roller 14 rotating within the guide rail 13 fixed to pins 14g and 14h.
i, 14j, pins 14k inserted into the long holes 15b, 15C of the door support plate 15 and the tips of the connecting arms 14C, 14d;
141 is a link mechanism, and 16 is a hinge consisting of a winding portion 15C provided at the front end of the door support plate 15, a pin 16a, a metal fitting 16b, and a screw 16C.

In the above configuration, the parts are joined together from the state shown in FIG. 6, these are attached to the partition plate 10f, and the respective plate materials 10a to 10f are joined from the state shown in FIG. 5. The cabinet is completed as shown.

Therefore, if you extend the knock mechanism and pull out the rear end of the door 12 to the front end of the cabinet 1 as shown in FIG. 4a or FIG.
It can be opened and closed at an angle of 180° (arrow A in FIGS. 4 to 7 a) or 180° (arrow B in FIGS. 4 to 7 a).

Then, when the door 12 is pushed in in the direction of arrow C shown in FIG.
It is stored in the door storage section 11 of 0.

FIG. 8 shows another embodiment of the present invention, in which the link mechanism 17 is composed of six connecting arms 17a to 17f,
The rear end is fixed to the partition plate 10f with a spacer 17g and a screw 17h, and one roller 17 is attached to the moving fulcrum.
i is mounted inside the guide rail 13.

If such a link mechanism 17 is used, the guide rail 1
Since the number of rollers rolling inside the door 12 is small, the operation of storing and pulling out the door 12 becomes easier.

In FIG. 8, parts with the same reference numerals as in FIGS. 4 to 7 have the same functions.

Further, the present invention has a cabinet 10 as shown in FIG.
It can also be applied to a system in which door storage sections are provided on both sides of the door 12a12b to store double doors 12a12b.

As described above, the present invention provides a guide rail in the front-rear direction of a vertically arranged surface inside the cabinet, and connects the movable fulcrum of the telescopic link mechanism vertically along the surface to the guide rail. Attach one of the moving fulcrums of the link mechanism to the center of the door support plate, and
The free ends of the forwardmost pair of connecting arms constituting the link mechanism are movably attached to a pair of elongated holes provided at the top and bottom of the door support plate, respectively, and The rear end of the door is rotatably attached at least at two points, upper and lower.

In this way, not only can the front of the cabinet be opened and closed with a door, but this door can also be pushed into the cabinet when it is not needed. By storing the door inside the cabinet, when the door protrudes into the aisle, the usability of the cabinet can be greatly improved.

Moreover, one of the moving fulcrums of the link mechanism is fixed to the center of the door support plate, and the free ends of the pair of connecting arms that are the most forward of the connecting arms that make up the link mechanism are provided above and below the door support plate. They are movably attached to a pair of elongated holes, and these three points connect the door support plate to the link mechanism, but the door support plate does not tilt forward or backward, and the depth of the cabinet increases as the link mechanism expands and contracts. Move smoothly in the direction.

And because the front end of this door support plate is rotatably attached at least two points on the rear end of the door, top and bottom, even though the door is arranged vertically, it can be taken in and out very smoothly without tilting forward or backward. Wear.

Therefore, even if the door is made of a heavy material such as glass, the operation of putting in and taking out the door can be made extremely stable.
