Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a desk connection structure suitably used in offices and the like.

[Prior Art] In offices and the like, it is not uncommon for desks, which are normally used alone for individual work, to be grouped together or placed adjacent to each other in the necessary number for use as desks for reception. Conversely, multiple desks that are used adjacent to each other may be separated and used again as individual desks. For this reason, in recent years, various efforts have been made to keep desks adjacent to each other and to connect them detachably. One of these is a connection structure in which top plates or side plates are connected relatively simply via fasteners, as is often seen in wooden desks that are difficult to process. .

Fig. 13 relates to a connection structure that connects top plates to each other.The top plate of desk a has a recess d that opens toward the lower surface C near the side edge, and this recess d and the top A bolt insertion hole f is bored horizontally between the side end surface e of the board. When the side end surfaces e of adjacent top plates are brought into close contact with each other, bolts g are inserted into both bolt insertion holes f, and nuts h are screwed into each of the through ends of the bolts in the recesses d. , the top plates can be connected to each other.

Further, FIG. 14 shows a connection structure for connecting side plates to each other, and a bolt insertion hole k is horizontally bored through the side plate of the desk i in the thickness direction.

Then, with the side end surfaces m of adjacent top plates ρ in close contact with each other, the bolt n inserted through the bolt insertion hole k of one desk i is passed through the bolt insertion hole of the other desk i, and this state is maintained. By screwing the nut o into the through end of the bolt n, the side plates j can be connected to each other. The bolt p and nut q shown in FIG. 15 are designed so that they can be screwed into each other within the bolt insertion hole to improve the appearance.

[Problems to be Solved by the Invention] However, in desk a that adopts the connection structure shown in FIG. The bolt insertion hole f is exposed on the side end surface e of the frame, resulting in an unsightly appearance. Also, in the case of the desk i that adopts the connection structure shown in FIGS. 14 and 15, when the desk i is used alone after removing the pole nSp, the bolt insertion hole k is inserted into the side plate j as shown in FIG. 17.
exposed, which also causes the inconvenience of being unsightly.

These inconveniences can be alleviated to some extent by covering the bolt insertion holes f and k with resin caps, etc., but offices these days are rapidly becoming more intelligent, and all types of furniture are becoming more functional. With the increasing demand for highly sophisticated designs, there is no way that discerning users will be willing to accept such inconveniences. In addition, small parts such as resin caps tend to be poorly managed during periods when they are not used, and if the period is long, they are often lost and unusable when you want to use them again.

On the other hand, for wooden desks, etc., where such complicated processing is difficult, it is not easy to provide a top plate and side plates that can be assembled and disassembled, and conventionally, the top plate and side plates were coated with adhesive. Usually, they are simply connected using dowels or the like. For this reason, most of the desks are completed at the factory stage, and there is a problem in that subsequent handling related to loading/unloading and inventory management is extremely inconvenient.

An object of the present invention is to provide a desk connection structure that can solve these problems all at once.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the following structure.

That is, in the desk connection structure according to the present invention, the top plates of adjacent desks are connected to each other via the connection plate. For this purpose, the six desks are fixed to the left and right side plates, a connecting fitting whose outer edge half is in contact with the upper end surface of the side plate, and a connecting fitting whose outer edge half is attached to the side plate from the upper surface side. A first fixing bolt to be attached to the top plate, a top plate whose side edge is attached to the upper end surface of the side plate via the connecting fitting, and a half half of the inner edge side of the connecting fitting attached to the top plate from the bottom side. a second fastening bolt fastened to the top plate, and a joint having the outer edge of the connecting fitting as the joint bottom is formed between the side end surface of the top plate and the outer surface of the side plate; By cutting out a portion of the connecting fitting within this joint, a slit that communicates with the inner surface of the side plate is formed.

Further, the connecting plate has one end side connected to the slit of one desk.
The other end can be inserted into the slit of the other desk. The device is characterized in that the through-end portions of the connecting plate are fixed to the corresponding desk top plates from the bottom side using connecting bolts.

In order to prevent the appearance of the top plate from increasing in thickness and becoming unsightly due to the interposition of connecting metal fittings between the top plate and the side plates, a step is formed on the bottom surface of the top plate so that it can be removed from the outside. It is effective to make the visible side edge portions thinner than the middle portion. In this case, there is a possibility that the connecting plate cannot be inserted, so a concave portion that is continuous with the lower surface of the side edge is formed at a portion of the lower surface of the intermediate portion corresponding to the slit, and the connecting plate is inserted into this concave portion. It must be guided so that it will stick to the large board. Moreover, as a result of this, it is no longer possible to simply use a flat plate-shaped connection fitting, but in that case, the connection fitting has a horizontal outer half half and a horizontal inner half half. It shall be continuous by the vertical plate part,
It is preferable that the slit is formed by partially cutting out a half portion of the outer edge side. Furthermore, in order to connect the desks that have been assembled together, a through hole is provided in the inner edge half at a portion corresponding to the recessed portion to allow insertion of a connecting bolt. It is better.

In order to freely realize a variety of connection forms by combining a plurality of desks having different shapes, it is sufficient to at least make the depth dimensions of the desks the same.

When one desk is used in conjunction with the other desk, the one desk can be a side table-shaped desk with a larger depth than the other desk.

A desk in which the top plate and copper plate are made of wood is an example of an embodiment in which the effects of the present invention are particularly noticeable.

[Function] With such a connection structure, by removing the connection bolt from the bottom of the rain top plate, pulling out the connection plate from the slit, and separating the top plates, it becomes possible to use them as independent desks. However, in this state, joints are exposed on the sides of each desk, and slits are opened at the bottom of the joints, but the joints themselves are essentially useful for improving the aesthetic appearance of the desk. Because the slit is located at the bottom of the joint, it is difficult for the slit to enter the human field of vision, and even if it does enter the field of view, it is at the same position as the joint, so it does not feel too strange. Therefore, compared to conventional connection structures in which bolt insertion holes are opened in locations that should be flush with each other, unsightliness can be significantly reduced. In addition, with such a device, there is no need to use resin caps or the like when six desks are used alone, so there is no need for troublesome management of small parts.

In addition, if the top plate and side plate are connected using such a connecting fitting, the outer edge half and the first fastening bolt will be completely covered by the side edge of the top plate and will not be exposed to the outside when the assembly is completed. Although the inner edge half and the second fixing bolt are exposed under the top plate, they are no longer visible to humans unless they look very far under the top plate. For this reason, it becomes possible to simply connect the top plate and the side plates without making them look unsightly, without having to perform complicated processing on them. Moreover, by loosening the second fastening bolt, the top plate can be removed from the connecting fitting, and from this state, by further loosening the first fastening bolt, the connecting fitting can be removed from the side plate. A desk that adopts a connecting structure allows the top plate, side plates, and connecting fittings to be easily assembled and disassembled at any time.

[Example 1] An example of the present invention will be described below with reference to FIGS. 1 to 11.

Desk A to which this connection structure is applied, as shown in FIG. It is equipped with Also,
A joint 6 and a slit 7 are formed on the sides. The desks A are adjacent to each other on the left and right, and the top plates 4 can be connected to each other via a connecting plate 8.

To explain specifically, the side plate 1, as shown in FIG.
It is made of wood and has a decorative board 12 attached to the entrance surface of a frame-shaped core material 11, and the upper end surface 1a has a total of 3 parts near the used edge, near the non-used edge, and in the middle part thereof. (Hereinafter, this will be referred to as "stopping position X."

(See Fig. 2) has an onime nut 13 driven into it.

As shown in FIGS. 1, 3, and 6 to 8, the connecting fitting 2 has a horizontal outer half half 21 and a horizontal inner half 22 connected by a vertical plate 23. Bolt insertion holes 24 that expand toward the upper surface 2b are formed at three locations on the outer edge half half 21 corresponding to the fixing positions X, and at these fixing positions Corresponding inner half half 2
Bolt insertion holes 25 that expand toward the bottom surface 2C at three locations in 2.
is drilled. In addition, a cutout portion 26 of a constant width is provided in the outer edge side half portion 21 corresponding to the area between the anchoring position X and the anchoring position In addition, a through hole 27 used as a hole is bored in the inner edge side half portion 22. Then, the lower surface 2C of the outer edge side half part 21 of this connection fitting 2 is
As shown in the figure, the first fixing bolt 3 is brought into contact with the upper end surface 1a of the side plate 1, and in this state, insert the first fixing bolt 3 into each bolt insertion hole 24 from the upper surface 2b side, and It is fastened to 13.

As shown in FIG. 3, the top plate 4 is made of wood and has a decorative board 42 attached to the entrance surface of a frame-shaped core material 41.
, there are onime nuts 4 at three locations corresponding to the fixing position X.
3 is entered. Further, the lower surface 4a has a side edge 4.
A stepped portion 44 is formed to make the thickness of the intermediate portion 1 thinner than the intermediate portion 4□. By attaching the lower surface 4a of the side edge portion 41 to the upper surface 2b of the outer edge side half portion 21 of the connection fitting 2, the stepped portion 44 is disposed along the vertical plate portion 23, and the intermediate portion 42 The lower surface 4a of the connecting fitting 2 is partially attached to the upper surface 2b of the inner half half 22 of the connecting fitting 2. and,
In this state, the second fixing bolt 5 is inserted into each bolt insertion hole 25 from the lower surface 2C side, and its tip is fastened to each blind nut 43. As shown in FIGS. 4 and 5, this top plate 4 has a concave portion 45 continuous to the lower surface 4a of the side edge portion 41 on the lower surface 4a of the intermediate portion 42 corresponding to the fastening position Y. (corresponding to the width and depth dimensions of the connecting plate 8 to be described later) is formed, and a blind nut 46 is also driven into this recessed portion 45.

In this way, the side plate 1 and the top plate 4 of this desk A are connected via the connecting fittings 2. In this state, as shown in FIG. 3, the outer edge 2a of the connecting fitting 2 is set to be recessed with respect to the outer surface 1b of the side plate 1 and the side end surface 4b of the top plate 4. It is used as a joint 6 for appearance. Also, the side plate 1 is inserted through the notch 26.
A slit 7 is formed to communicate the inside and outside of the case.

Then, as shown in FIGS. 1 and 11, the side end surfaces 4b of these desks A are brought into close contact with each other and adjacent to each other on the left and right, and bolts that expand downward at both ends as shown in FIGS. 9 and 10 are installed. A connecting plate 8 having an insertion hole 8a is inserted into both slits 7,
In this state, pass the bolts 9 inserted through the through holes 27 of the connecting fitting 2 into the bolt insertion holes 8a of the connecting plate 8, and tighten them from the lower surface 4a side to the corresponding nuts 46 provided on the top plate 4 of the desk A. By attaching the top plates 4 to each other, the top plates 4 are connected to each other.

With such a connection structure, each desk A can be used independently by removing the connection bolt 9 from the lower surface 4a of the rain top plate 4, pulling out the connection plate 8 from both slits 6, and separating the top plates 4 from each other. becomes possible. In this state, as shown in FIGS. 1 and 2, the joint 6 is exposed on the side of the desk A, and the slit 7 is opened at the bottom 2a of the joint, but the joint 6 itself is Since slit 7 is located at the bottom of the joint, it is difficult to see the human field of view, and even if it is in the field of view, it is useful for improving the aesthetic appearance of desk A. Since they are in the same position, you won't feel any discomfort. Therefore, compared to conventional connection structures in which bolt insertion holes are unnaturally opened in locations that should be flush with each other, it is possible to significantly reduce unsightliness. In addition, with such a device, when the six desks A are used alone, there is no need to cover the slit 7 with a resin cap or the like, so there is no need for troublesome management of small parts.

Furthermore, if the connecting fitting 2 that connects the top plate 4 and the side plate 1 is of this type, the outer edge half half 21 and the first fastening bolt 3 will be completely covered by the top plate 4 in the assembled state. Therefore, it is no longer exposed to the outside, and the inner edge side half 22 and the second
Although the fixing bolts 5 are exposed on the lower surface 4a of the top plate 4,
If you don't look very closely into that part, it won't come into the human field of vision. For this reason, it is possible to simply connect the top plate 4 and the side plates 1 without making them look unsightly without performing any additional processing on them. Furthermore, by loosening the second fastening bolt 5, the top plate 4 can be removed from the connecting fitting 2, and from this state, by further loosening the first fastening bolt 3, the connecting fitting 2 can be removed from the side plate 1. Therefore, in this desk A, the top plate 4, side plate 1, and connection fittings 2 can be easily assembled and disassembled at any time. This makes it possible to effectively eliminate handling problems related to loading/unloading and inventory management that conventional wooden desks have had.

Note that the present invention is not limited to the illustrated example. For example, in the above embodiment, the same desk is used for the left and right desks, but the present invention can also be applied to desks with different shapes. In this case, if at least six desks are provided with the same depth dimension, these desks can be combined and connected in a variety of ways, which is effective in improving functionality. Also,
As shown in FIG. 12, one desk B is replaced by desk A of the above embodiment.
It is also possible to use a desk in the form of a side table with a larger depth dimension. This desk B has a top plate 10 in the same manner as in the above embodiment.
A joint 106 is formed between the side end surface 104b of No. 4 and the outer surface 101b of the side plate 101, and at the bottom of the joint,
A communicating slit 107 is formed on the inner surface of the side plate 101. Desks A and B can be connected to desk B by inserting the connection plate 8 of the above embodiment into both slits 107 and fixing it to the lower surface of the top plate 104. Furthermore, this connection structure is not limited to those in which the top and side plates are made of wood, and can be applied to desks with similar problems to obtain similar effects. In addition, the cross-sectional shapes of the connecting fittings, joints, slits, etc. are not limited to the illustrated examples, and various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] According to the desk connection structure according to the present invention, the top plates of adjacent desks can be reliably connected by the connection plate, and moreover, when the connection plate is removed and six desks are used alone, Since the slit into which the connecting plate was inserted opens at the bottom of the joint where it is not conspicuous, it has little effect on the appearance.Furthermore, there is no need to cover the slit with a resin cap, which is a hassle. This frees you from managing small parts, and furthermore, by attaching and detaching the first and second fixing bolts, you can easily assemble and disassemble the top plate, side plates, and connecting fittings, so you can easily use wooden desks, etc. This has the effect of effectively resolving the handling problems that the company had.
