Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a disc plate which can rotate between a substantially vertical standing state and a substantially horizontal lying state, and can be slid forward and backward in the horizontally lying state. Related to furniture.

[0002]

2. Description of the Related Art Furniture equipped with the above disc plate is usually called a writing disc. Not only can it be used for both desks and storage furniture, but when it is not used as a desk, the disc plate can be raised. It has the advantage that the occupied space can be reduced.

The disc plate is not only rotatably provided, but also slidable in the front-rear direction, and has a protruding length from the front surface of the main body of a box-shaped piece of furniture depending on the use form. It can be changed.

As a structure in which the disc plate is rotatably and slidably provided with respect to the main body, it is disclosed in Japanese Utility Model Publication 62-37.
The one shown in Japanese Patent No. 485 is known. In the structure disclosed in this publication, as shown in FIG. 6, a horizontal groove rod 3 having a circular bearing housing 2 at its tip is embedded in the inner surface of the side plate 1 of the writing disc. A circular rotary bearing 5 having a groove 4 is rotatably accommodated in the circular bearing accommodating portion 2.

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

Therefore, the deck 6 slides in the front-rear direction by sliding the horizontal slide piece 8 on the horizontal groove rod 3, and the horizontal slide piece 8 is positioned in the groove portion 4 of the circular rotary bearing 5. If it is slid forward until then, it can be rotated and raised with the circular rotary bearing 5 at that position.

A receiving plate 9 is installed between the side plates 1, and support pieces 10 are provided on both ends of the upper surface in the width direction.
The support 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 at the rear end side by the engagement of the groove portion 4 of the circular rotary bearing 5 and the horizontally long sliding piece 8 and the lower surface of the middle portion is supported by the supporting piece 9. Become.

According to this structure, when a load is applied to the top end of the upper surface of the deck 6 supported in the horizontal state, the load causes the deck 6 to rotate in the direction of rotation in the direction indicated by the arrow in FIG. -Mention occurs. The moment will be received by the laterally long sliding piece 8 engaged with the groove portion 4 of the circular rotary bearing 5.

However, the laterally long sliding piece 8 is the deck 6
It is joined and fixed to the side end surface of the with screws. for that reason,
There is a risk that the laterally elongated sliding piece 8 may be separated from the side end surface of the deck 6 due to a moment applied to the deck 6, and the deck 6 cannot be supported horizontally.

By increasing the length of the above-mentioned laterally long sliding piece 8,
By improving the joint strength to the side end surface of the deck 6,
It is considered that it is difficult to peel off. However, if the horizontally long sliding piece 8 is lengthened, not only does the sliding resistance increase and it becomes difficult for the deck 6 to slide smoothly, but also the horizontally long sliding piece 8
There was a case where the joint strength with the deck 6 could not be sufficiently enhanced even if the length was increased to some extent.

[0011]

As described above, when the conventional disc plate is laid down substantially horizontally and used, it is provided on both widthwise end faces of the rear end of the disc plate by the load applied to the upper face thereof. Since the horizontally long sliding member is easy to peel off,
There was a case where sufficient supporting rigidity could not be obtained.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent the supporting state from being easily damaged even if a load is applied to the upper surface of the disk plate in a horizontally supported state. The purpose is to provide the furniture.

[0013]

The invention according to claim 1 has a main body formed in a substantially box shape, and a disc plate is erected substantially vertically on the front surface of the main body and is laid down substantially horizontally. In a furniture that is held to be slidable in the front-rear direction in a state in which it is pivotable between the states and lying substantially horizontally, a locking member erected along the width direction at a middle portion in the height direction of the main body, A front member that is provided on the front surface side of the main body with its upper end positioned below the locking member, and supports the lower surface by the upper end when the disc plate is laid down substantially horizontally; , A slide groove formed on the lower surface side of the locking member along the front-rear direction and having a front end side curved downward, and a state in which the lower end portion of the disk plate is bent toward the inner surface side of the upright disk plate. Horizontally lying de A movable member that is rotatably connected between the disk member and the disk member, and a shaft-shaped member that projects from both ends of the movable member in the width direction and that is slidably engaged with the slide groove. The shaft-shaped member engages with the front end of the slide groove in a state where the disc plate is erected, and when the disc plate is laid down substantially horizontally and slid backward, the movable member is It is characterized in that it is held in a state of being joined to or close to the locking member.

According to the first aspect of the present invention, the horizontally lying disk plate has a movable member which is flush with the disk plate and abuts against the lower surface of the locking member, and a front member whose upper end abuts against the lower surface. Supported by and. Therefore, since the disk plate is supported by the movable member that is in contact with the lower surface of the locking member over substantially the entire width direction, the disk plate has sufficient rigidity with respect to the load applied to the upper surface thereof.

[0015]

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

On the front surface of the main body 12, the first shelf 1
A band plate-shaped front member 16 is provided below 3 along the width direction. A pair of hinged doors 17 are provided below the front member 16 so as to be openable and closable. As a result, a lower housing 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 portion 15 is opened and closed by a disc plate 19. At the lower end of the disc plate 19, a strip-shaped movable member 21 is provided, one end of which is rotatably connected by a hinge 22. The hinge 22 connects the movable member 21 to the disc plate 19
Is rotatably connected within a predetermined range.

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

The movable member 21 is inserted into the lower housing portion 18 from between the first shelf plate 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 thereof are provided with the side plates. The inner surface of 12a is slidably engaged with a slide groove 23 formed in the lower portion of the first shelf plate 13.

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

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

When the apparatus is erected from a substantially vertical state shown in FIG. 1 to a substantially horizontal state as shown in FIG.
Is 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 straight portion 23a. That is, the movable member 21 slides inward of the main body 1 by the dimension indicated by dimension A in FIG.

From this state, the disc plate 9 is pressed inwardly of the main body 2, and the shaft member 12 is moved to the linear portion 13 as shown in FIG.
When it is slid to the rear of a, since the linear portion 13a is inclined upward, the upper surface of the movable member 21 comes close to the lower surface of the first shelf plate 13 in a state of being joined or slightly separated. In this embodiment, they are joined together.

The diameter of the shaft member 22 is set slightly smaller than the width of the slide groove 23.
As a result, the shaft-shaped member 22 can be displaced in the vertical direction, so that even if the movable member 21 is not joined 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-shaped 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 plate 13.

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

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

According to the writing disc 11 thus constructed, when a load is applied to the upper face of the disc plate 19 which is laid down substantially horizontally and slid rearward, the upper end of the front member 16 is attached to the disc plate 19. The curved surface 16a is used as a fulcrum to raise the rear end side.

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

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

[0030]

As described above, according to the present invention, the horizontally lying disc plate is flush with the disc plate, is in contact with the lower surface of the locking member, and the upper end is in contact with 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 by contacting the lower surface of the locking member with the movable member and the rear end of the disk plate over substantially the entire width direction. The supporting rigidity of the plate can be sufficiently increased.
