DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a disk plate which can be rotated between a state of standing substantially vertically and a state of lying down substantially horizontally, and which can be slid in the front-rear direction while lying down horizontally. About furniture.

[0002]

2. Description of the Related Art Furniture provided with the above-mentioned disk plate is usually called a writing disk, and can be used not only as a desk and storage furniture, but also when the disk plate is not used, the disk plate can be raised. This has the advantage that the occupied space can be reduced.

The above-mentioned disk plate is provided not only rotatably but also so as to be slidable in the front-rear direction, and the length of the furniture protruding from the front surface of the box-shaped body is determined according to the usage. It can be changed.

A structure in which the disk plate is provided rotatably and slidably with respect to the main body is disclosed in Japanese Utility Model Publication No. 62-37.
No. 485 is known. In the structure disclosed in this publication, as shown in FIG. 6, a horizontal grooved rod 3 having a circular bearing housing 2 provided at the end is embedded in the inner surface of a side plate 1 of a writing disk. A circular rotary bearing 5 in which a groove 4 is formed is rotatably stored in the circular bearing housing 2.

On the other hand, a rising plate 7 is provided at the rear end of a deck 6 (disk plate) of the writing disk, and a horizontally long sliding piece 8 is attached to both ends in the width direction. It is slidably engaged with the horizontal groove type rod 3.

Therefore, the deck 6 slides in the front-rear direction by the horizontal sliding piece 8 sliding on the horizontal grooved rod 3, and the horizontal sliding piece 8 is positioned in the groove 4 of the circular rotary bearing 5. If it is slid forward until it does, it can rotate with the circular rotary bearing 5 at that position and stand up.

[0007] A receiving plate 9 is provided between the side plates 1, and supporting pieces 10 are provided at both ends in the width direction of the upper surface.
The supporting piece 10 supports the lower surface of the deck 6 in a horizontal state. That is, the deck 6 in the horizontal state is supported by the engagement between the groove 4 of the circular rotary bearing 5 and the horizontally long sliding piece 8 at the rear end side, and the lower surface of the halfway portion is supported by the supporting piece 9. Become.

According to such a configuration, when a load is applied to the top end of the upper surface of the deck 6 supported in a horizontal state, the load causes the deck 6 to rotate in the rotational direction indicated by the arrow in FIG. -Ment occurs. The moment is received by the horizontally long sliding piece 8 engaged with the groove 4 of the circular rotary bearing 5.

However, the horizontally long sliding piece 8 is
Is fixedly joined to the side end surface with screws or the like. for that reason,
Moment applied to the deck 6 may cause the horizontally long sliding piece 8 to be separated from the side end surface of the deck 6 and may not be able to support the deck 6 horizontally.

The length of the horizontally long sliding piece 8 is increased,
By improving the bonding strength to the side end surface of the deck 6,
It is conceivable to make peeling difficult. However, when the length of the horizontally long sliding piece 8 is increased, not only the sliding resistance is increased and it becomes difficult to slide the deck 6 smoothly, but also the horizontally long sliding piece 8
However, there is a case in which the bonding strength with the deck 6 cannot be sufficiently increased even if the length is increased to some extent.

[0011]

As described above, the conventional disk plate is provided on both widthwise end surfaces of the rear end of the disk plate due to the load applied to the upper surface when the disk plate is used while lying down substantially horizontally. Because the horizontally long sliding member is easy to peel off,
In some cases, sufficient support rigidity could not be obtained.

The present invention has been made based on the above circumstances, and an object of the present invention is to prevent a disc plate from being supported horizontally even if a load is applied to its upper surface while the disc plate is supported horizontally. To provide customized furniture.

[0013]

According to the first aspect of the present invention, there is provided a main body formed substantially in a box shape, and a disk plate is erected almost vertically and substantially horizontally on the front surface of the main body. In a furniture that is held slidably in a front-rear direction while being rotatable and substantially horizontally laid down with a state, a locking member erected along a width direction in a height direction halfway portion of the main body, A front member provided on the front side of the main body with an upper end positioned below the locking member, and a lower surface supported by the upper end when the disc plate is laid down substantially horizontally; A sliding groove formed along the front-rear direction on the lower surface side of the locking member and having a front end curved downward, and a state in which the lower end of the disk plate is bent toward the inner surface side of the disk plate standing upright. A horizontally lying de A movable member rotatably connected to a state in which the movable member is substantially flush with the scoop plate; and a shaft-like member protruding from both ends in the width direction of the movable member and slidably engaged with the slide groove. The shaft-shaped member is engaged with the front end of the slide groove in a state where the disc plate is raised, and the movable member is moved when the disc plate is laid down substantially horizontally and slid backward. It is characterized in that it is configured so as to be joined to or close to the locking member.

According to the first aspect of the present invention, the disk plate which has fallen horizontally has a movable member which is flush with the disk plate and abuts on the lower surface of the locking member, and a front member whose upper end abuts on the lower surface. And supported by. Therefore, the disk plate is supported by the movable member abutting on the lower surface of the locking member for substantially the entire length in the width direction, and thus has sufficient rigidity against a load applied to the upper surface thereof.

[0015]

An embodiment of the present invention will be described below with reference to the drawings. A writing disc 11 as furniture of the present invention shown in FIGS. 4 and 5 includes a box-shaped main body 12 having an open front surface. A first shelf plate 13 as a locking member whose both ends are supported and fixed between a pair of side plates 12a is installed substantially horizontally at an intermediate portion in the height direction in the main body 12. Above the first shelf 13, a second shelf 14 having a smaller depth dimension is provided in parallel with the first shelf 13. The upper section defined by the first shelf 13 in the main body 12 is an upper storage section 15.

At the front of the main body 12, the first shelf 1
A band-shaped front member 16 is laid along the width direction below 3. A pair of hinged doors 17 are provided below the front member 16 so as to be freely opened and closed. Thereby, a lower storage portion 18 that is opened and closed by the hinged door 17 is formed inside the main body 12.

The front opening of the upper housing 15 is opened and closed by a disk plate 19. At the lower end of the disk plate 19, a strip-shaped movable member 21 is provided with one end rotatably connected by a hinge 22. The hinge 22 connects the movable member 21 to the disk plate 19.
Are rotatably connected within a predetermined range.

That is, the movable member 11 is prevented from rotating downward from the horizontal state, which is flush with the disk plate 19, which is substantially horizontal as shown in FIG. From this state, as shown in FIG. 1, the disk plate 19 can be turned inward.

The movable member 21 is inserted into the lower accommodating portion 18 from between the first shelf 13 and the upper end of the front member 16, and the shaft-like members 22 projecting from both end surfaces in the width direction are connected to the side plate. The inner surface 12a is slidably engaged with a slide groove 23 formed in the lower part of the first shelf plate 13.

The slide groove 23 has a straight portion 23a and a curved portion 23b which is continuous with the front end of the straight portion 23a. The straight portion 23a is slightly higher inclining toward the rear of the main body 12, and the curved portion 23b is curved downward in an arc shape.

When the disk plate 19 is erected substantially vertically, the shaft-like member 22 bends the movable member 21 and is located at the tip (lower end) of the curved portion 23b of the slide groove 23. As a result, the disk plate 19 that stands substantially vertically is prevented from moving forward from a state where the lower end is joined to the upper end of the front member 16.

When the robot is laid down substantially horizontally as shown in FIG. 2 from the state of standing substantially vertically as shown in FIG.
Are substantially flush with the disk plate 19. Thereby, the shaft-shaped member 22 automatically slides from the curved portion 23b of the slide groove 23 to the linear portion 23a. That is, the movable member 21 slides inward of the main body 1 by the dimension indicated by the dimension A in FIG.

In this state, the disk plate 9 is pressed inward of the main body 2, and as shown in FIG.
When the slider is slid rearward, the upper surface of the movable member 21 comes closer to the lower surface of the first shelf plate 13 while being joined or slightly separated because the linear portion 13a is inclined upward. In this embodiment, they are joined.

The diameter of the shaft member 22 is set slightly smaller than the width of the slide groove 23.
As a result, the shaft-like member 22 can be displaced in the up-down direction, so that the movable member 21 does not join to the lower surface of the first shelf plate 13 when the disk plate 19 is slid backward, When a force is applied, the shaft member 22 is displaced upward in the width direction of the slide groove 23, so that the upper surface of the movable member 21 is joined to the lower surface of the first shelf 13.

Therefore, the disk plate 19 is supported in a substantially horizontal state by the first shelf plate 13 whose upper surface is joined and the front member 16 whose outer surface (lower surface) is joined to the lower end (rear end). ing.

The upper end of the front member 16 has an arcuate curved surface 16a so that the disk plate 19 can be easily slid.
Is formed. In addition, as shown in FIG. 5, the upper part of the disk plate 19 which is erected substantially vertically is held by a metal part 24 provided on the inner surface of the upper part thereof by magnetic coupling with a magnet part 25 provided on the upper part of the main body 12. It has become so.

According to the writing disk 11 configured as described above, when a load is applied to the upper surface of the disk plate 19 laid down substantially horizontally and slid backward, the upper end of the front member 16 is applied to the disk plate 19. A moment of raising the rear end side with the curved surface 16a as a fulcrum occurs.

When a moment is generated in the disk plate 19, the movable member 21 and the disk plate 19 come into contact with the lower surface of the first shelf plate 13 to receive the moment. That is, the substantially entire length of the movable member 21 and the rear end of the disk plate 19 in the width direction is joined to the lower surface of the first shelf plate 13 to receive the moment.

Accordingly, the load applied to the substantially horizontally supported disk plate 19 is limited to the first shelf plate 13 and the movable member 2.
1 and the rear end of the disk plate 19 are received by contact over the entire length in the width direction, so that the disk plate 19 is supported with sufficient rigidity against the load applied to the upper surface.

[0030]

As described above, according to the present invention, the disk plate which has fallen horizontally has the same plane as the disk plate, and the movable member abutting on the lower surface of the locking member and the upper end abutting on the lower surface. It is supported substantially horizontally by the front member.

Therefore, when a load is applied to the upper surface of the disk plate, the load is received substantially in the width direction of the movable member and the rear end portion of the disk plate in contact with the lower surface of the locking member. The support rigidity of the plate can be sufficiently increased.
