Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to system furniture.

[0002]

2. Description of the Related Art Furniture belonging to a new category called system furniture has begun to be produced mainly in Europe. This product uses one indoor wall, and on this wall, various functions such as bookshelf, desk, TV stand, etc.
A part having a purpose is systematically three-dimensionally arranged. In this way, it is easier to harmonize the texture, color, and the like, and it is easier to obtain a uniform appearance as compared to a case where single furniture such as a bookshelf, a desk, and a TV stand are simply arranged along the wall surface.

[0003] The system furniture can take various combinations, and a minimum unit which is simplified as much as possible in structure is shown in FIG. 37. That is, the minimum unit is two side plates 1, 2 standing upright.
And a horizontal top plate 3 located at the upper end of the side plates 1 and 2 and a bottom plate 4 located at the lower end (a skirting board may be substituted).
And a middle shelf 5, which are combined to form a three-dimensional shape.

Then, in order to have sufficient strength in this structure without using a jig which is exposed to the outside and impairs the appearance like an L-shaped bracket, as shown by arrows,
The top plate 3, the bottom plate 4, and the shelf plate 5 are fixed to the side plates 1 and 2 using screws 6 from the outside of 2. That is, in this structure, the ends of the plurality of horizontal plates (top plate 3, bottom plate 4, and shelf plate 5) are brought into contact with the facing surfaces of the side plates 1 and 2, and the ends of the plurality of horizontal plates are connected. , Must be linearly coupled to the side plates 1 and 2.

If an attempt is made to construct only a single horizontal plate, as shown in FIG. 38, the posture of the side plates 1 and 2 is not stable, and the strength is insufficient. Also, on the back of the side plates 1 and 2,
It is conceivable that the backboard (not shown) is fixed and reinforced, but there are cases where it is desired to make the wall behind the system furniture visible, so that sufficient strength should be provided without the backboard. is there.

[0006]

From the above, in the conventional system furniture, the minimum unit as shown in FIG. 37 must be adopted. However, the system furniture is often arranged on the entire wall surface of the room, and the top plate 3 is often located at a high place, so that the work of screwing the top plate 3 becomes difficult.

Further, separate members are often arranged on the left and right of the minimum unit in FIG. 37, and a stop S for screwing the screw 6 is closed by another member, and the screwing itself is stopped. May be impossible. Of course, in such a case, if you select another position that does not interfere with another member and screw it,
Although screwing itself is possible, the degree of freedom of layout of the shelf plate 5 and the like is reduced.

Accordingly, an object of the present invention is to provide a system furniture that can easily connect adjacent side plates and has a high degree of freedom in layout.

[0009]

According to the system furniture of the present invention, a plurality of side plates which stand upright and parallel so that the distance between the centers becomes a predetermined value, and a pair of right and left rigidly connected so as to be orthogonal to each other. A connection box having a vertical plate and a pair of upper and lower horizontal plates, and wherein the vertical plate is formed so as to be able to adhere to the opposing surface of the adjacent side plate, at least one connection box between the opposing surfaces of the adjacent side plates. Are arranged, and a pair of left and right vertical plates of the connection box are fixed in a planar manner to opposing surfaces of the side plates that are in close contact with each other, so that adjacent side plates are rigidly connected. With this configuration, it is possible to easily connect adjacent side plates and realize a system furniture having a high degree of freedom in layout.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the system furniture according to the first aspect, a plurality of side plates which stand vertically and in parallel so that a distance between centers becomes a predetermined value, and a pair of left and right rigidly connected so as to be orthogonal to each other. A connection box having a vertical plate and a pair of upper and lower horizontal plates, and wherein the vertical plate is formed so as to be able to adhere to the opposing surface of the adjacent side plate, at least one connection box between the opposing surfaces of the adjacent side plates. Are arranged, and a pair of left and right vertical plates of the connection box are fixed in a planar manner to opposing surfaces of the side plates that are in close contact with each other, so that adjacent side plates are rigidly connected. With this configuration, the adjacent side plates are rigidly connected in a planar manner by the connection box. Therefore, the adjacent side plates and the connection box sandwiched therebetween constitute a structural minimum unit, and sufficient strength can be obtained only with the minimum unit. Also,
The connection box does not necessarily need to be fixed at a high position like a top plate, and the connection operation can be easily performed at a position where the operator can easily reach. Note that the horizontal plate of the connection box can be used as a shelf plate or a table.

Then, a pair of left and right vertical plates of the connection box are fixed in a planar manner to the opposing surfaces of the side plates that are in close contact with each other, thereby forming a single-type storage furniture. With this configuration, a structurally stable and self-supporting storage furniture can be configured only by fixing the connection box between the two side plates in a planar manner.

[0013] In the system furniture according to the third aspect, the pair of left and right vertical plates of the connection box is stopped by a jig from the inside of the connection box to the side plate closely contacted. With this configuration, the worker can easily perform the fixing work by putting his hand inside the connection box. In addition, even if another member exists outside the side plate, the stop is inside the connection box, so that screwing can be performed without interfering with another member. Further, the connection box can be fixed at an arbitrary position without being disturbed by another member, and the degree of freedom in layout can be improved.

In the system furniture according to the fourth aspect, a arbitrarily selected one of a top plate, a shelf plate, and a baseboard is attached between adjacent side plates. With this configuration, not only can various functions and applications be realized, but also it is not necessary to fix the shelf boards and the like for the purpose of securing structural strength. be able to.

In the system furniture according to the fifth aspect, the back plate is attached to the back of the adjacent side plate, and the door is attached to the front of the adjacent side plate so as to be openable and closable. With this configuration, a closed space can be formed between the adjacent side plates, and a part or all of the system furniture can exhibit functions such as a closet and a cupboard.

In the system furniture according to the sixth aspect, one or more drawers are housed in the connection box so that they can be freely taken in and out. With this configuration, the drawer can be incorporated into the system furniture.

Next, an embodiment of the present invention will be described with reference to the drawings. As described above, in the system furniture according to the present embodiment, the adjacent side plates and the connection box fixed to the adjacent side plates form a structural minimum unit. The connection box has a pair of left and right vertical plates and a pair of upper and lower horizontal plates rigidly connected to be orthogonal to each other, and is formed so that the vertical plates can be in close contact with the opposing surfaces of the adjacent side plates. .

As will be described later, the system furniture of the present embodiment can take various forms (single type or composite type) depending on the combination of components. The components used will be described. Here, FIG. 1 is a horizontal sectional view of the system furniture in one embodiment of the present invention.

In FIG. 1, reference numerals 10 and 11 denote side plates which stand upright and parallel to each other.

In this example, in the case where the cupboard is the main element, the depth D is 300 mm, and similarly, D = 4 in the bookcase and the lower foot box.
00 mm, and D = 560 mm in the closet. The distance DW between the centers of the side plates 10 and 11 is a predetermined value (in this example, 500 mm (FIG. 3A)) or 1000 mm.
(FIG. 3B)). In addition, the configuration in FIG. 3 is a single type, but it can be a composite type by connecting this along a wall surface and sharing a side plate.
Further, as shown in FIGS. 4A and 4B, a single type may be combined horizontally. The side plates 10 and 11 are essential components of a minimum unit. When the side plates 10 and 11 are installed, a correction bracket for position correction is attached to a lower end thereof, and the position is finely adjusted with the correction bracket to perform accurate positioning. .

In FIG. 1, reference numeral 12 denotes side plates 10, 1;
1 is a back plate attached to the back of the vehicle 1 according to the dimensional system of FIG. Here, as shown in FIG. 6A, when the baseboard 15 is not used, when the baseboard 15 is used, as shown in FIG. It is shortened by the height of the baseboard 15. In FIG. 1, reference numeral 13 denotes the side plate 1.
The front doors 0 and 11 are doors that can be freely opened and closed using, for example, hinges or the like. The door 13 is based on the dimensional system shown in FIG. 7 when it is made of a wooden plate, and is based on the dimensional system shown in FIG. 8 when it is made of a framed glass plate. Here, depending on whether the baseboard 15 is used or not, the height is set as shown in FIG.

With this dimensional system, door 1
3 is located at the center of the side plates 10 and 11. More specifically, in the case of a single opening, the state is as shown in FIG. 9A, and in the case of a double opening, the state is as shown in FIG. 9B. Further, also in the vertical direction, as shown in FIG. 10, the upper and lower ends of the door 13 are positioned at the center of a shelf plate, a top plate, a bottom plate and the like that open and close.
In this way, even if the door 13 is opened and closed, it can be prevented from interfering with other members such as doors and drawers.

The top plate 14 and the bottom plate (not shown)
According to the dimensional system shown in FIG. The top plate 14 and the bottom plate are shown in FIG.
As shown in FIG. 1 (c), the side plates 10 and 11 are supported in an inward manner at the upper ends thereof.

When the shelf board is made of a wooden board, FIG.
In the case of using a glass plate according to the dimensional system of (a) and (b), the dimensional system of FIGS. 12C and 12D is used. Like the top plate 14, the shelves are to be stored in secret.

The baseboard 15 is constituted by the dimensional system shown in FIGS. 13A and 13B, and as shown in FIG.

The side plates 10 and 11 are essential components, but a top plate, a shelf plate,
The baseboard and the bottom plate are optional components that are added as needed.

Then, when these parts are combined,
A block that fits within a virtual prism based on the dimension system shown in FIGS. 14A to 14E can be configured. Further, when these blocks are stacked vertically, a virtual prism as shown in FIGS. 15A to 15C can be formed.

The imaginary prisms shown in FIGS. 14A to 14E are determined in consideration of the housing situation, ease of use of the user, and the like. If
Within these virtual prisms, a block that fits exactly can be configured, and by combining this block with the functions required by the user, similar to conventional system furniture,
The organic combination of functions can be realized while ensuring the uniformity of appearance.

Next, a connection box, which is an essential component of the minimum unit, will be described with reference to FIGS. Here, as shown in FIG. 16, it is assumed that the positioning of the side plates 10, 11 has already been completed. At this time, as shown by the broken line in FIG. 16, the connection box 20 is sandwiched between the opposing surfaces of the side plates 10 and 11. The connection box 20 includes a pair of left and right vertical plates 21 and 22 and a pair of upper and lower horizontal plates 23 and 24 that are rigidly connected to be orthogonal to each other.

Here, preferably, the thickness D2 of the vertical plates 21, 22 is made smaller than the thickness D1 of the horizontal plates 23, 24. In this way, the volume occupied by the connection box 20 can be effectively reduced. In addition, the connection box 20 is fixed at the storage location of the drawer 25 and the drawer 25 is connected to the connection box 2.
When the connection box 20 is stored so as to be freely taken in and out, the connection box 20 can be stored around the drawer 25 (a space that cannot be used originally), and the substantial occupied volume of the connection box 20 can be virtually eliminated. it can.

Then, as shown in FIG. 16, the vertical plates 21 and 22 of the connecting box 20 are brought into close contact with the opposing surfaces of the side plates 10 and 11, and as shown by arrows N, the vertical plates 21 and , 22 to the side plates 10, 11, and the side plates 10, 11 are fixed to the connection box 20 in a planar manner.
The side plate 1 is only fixed by the vertical surfaces 21 and 22.
Nos. 0 and 11 are usually rigidly connected with sufficient strength, and do not perform the posture deformation as shown in FIG.

Further, as is apparent from FIG. 16, the screw stop is secured inside the connection box 20, and the side plate 10,
Even if another member is present outside of 11, it can be easily screwed without being disturbed by this other member. In addition, the position of the connection box 20 is arbitrary and is not restricted to a high position unlike the top plate 14, so that a height that can be easily reached by the operator can be selected, and the fixing work can be further performed. Becomes easier. In addition, doors 13 and shelves can be added according to the user's request to configure a single-unit (one using one virtual prism in FIG. 14 or 15) system furniture as shown in FIG. . Further, the connection box 20 does not have to be a single connection box, and a plurality of connection boxes 20 and 20 ′ may be adopted for a single system furniture as shown in FIG.

FIGS. 16 and 17 show the simplest form of the connection box. However, as long as the two vertical plates and the two horizontal plates are rigidly connected so as to be orthogonal to each other, the upper horizontal plate may be formed into a shape that is easy to use as a desk base as shown in FIG. It can have various valuations, such as by making it easy to use as a computer desk like.

And as a single type system furniture,
