Abstract

PURPOSE:To eliminate the need for control of small parts when using independently each desk by fixing on the corresponding ceiling of the desk the penetrating part on both ends of a connecting plate the both ends of which can be penetrated into right and left slits of a desk by using a fixing device. CONSTITUTION:Desks 1L, 1R is constituted with a texture 4 which includes a texture bottom on the external periphery of the upper end between the side end surface 2b of the ceiling plate 2 and the external side surface 3b of a side plate 3. Then the side end surfaces 2b are bonded together so as to be placed in an adjacent position. Then a connecting plate 6 having a bolt through hole 6a on both ends are inserted from a slit 5 of one of the desks 1R (1L) to pass through the slit to the outside. A bolt 8 is penetrated through a bolt through hole 6a on the connecting plate 6 to connect the ceilings 2. In this connecting structure the bolt 8 is removed from the lower surface of the plate 2 and each desk 1L, 1R can independently be used. Besides the slit 5 is located on the bottom texture. Since the slit is located on the same position with the texture 4, it becomes obscure.

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, recently, when desks are placed adjacent to each other, connection structures have been considered in which the top plates or the side plates are removably connected to each other using fasteners.

Figure 6 is related to the connection structure that connects the top plates.
The top plate of desk a has a recess d that opens toward the lower surface C near the side edge, and a bolt insertion hole f is horizontally formed between this recess d and the side end surface e of the top plate. It is drilled in. Then, when bringing the side end surfaces e of adjacent top plates into close contact with each other, bolts g are inserted into both bolt insertion holes f,
The top plates can be connected to each other by screwing a nut h into each of the through ends in the recessed part d.

Moreover, FIG. 7 relates to a connection structure for connecting side plates to each other, and a bolt insertion hole k is horizontally bored through the side plate j of the desk i in the thickness direction. And the adjacent top plate g
With their side end faces m in close contact with each other, the bolt n inserted from the bolt insertion hole k of one desk i is passed through the bolt insertion hole of the other desk i, and in this state, the through end of the bolt n is inserted. By screwing in nuts 0, the side plates j can be connected to each other. The bolt p and nut q shown in FIG. 8 are designed so that they can be screwed together in 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 machine i that adopts the connection structure shown in FIGS. 7 and 8,
When the bolts n and p are removed and the desk i is used alone, the bolt insertion hole k is exposed in the side plate j as shown in FIG. 10, which also causes an unsightly appearance. Although these inconveniences can be alleviated to some extent by blocking the bolt insertion holes f and k with resin caps, etc.
Modern offices are rapidly becoming more intelligent, and all types of furniture are now required to be highly sophisticated in terms of functionality and design. There is no way that this would be easily accepted by discerning users. 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.

The present invention aims to effectively solve such problems.

[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, desks each having a top plate, a side plate, a joint, and a slit are adjacent to each other on the left and right, and the top plates of each desk are connected to each other via a connection plate. That's what I do. The side plates are joined to the lower surface of the top plate along the left and right edges of the top plate, and the joint is formed between the side end surface of the top plate and the outer surface of the side plate, and the joint is located at the bottom of the joint. The slit extends horizontally from the joint bottom in the thickness direction of the side plate and communicates with the inner surface of the side plate, and the connecting plate has both ends inserted into the slits of the left and right desks, respectively. It's something you get. The connecting plate is characterized in that the through-end portions of the connecting plate are fixedly attached to the corresponding desk top plate from the lower surface side using fasteners.

In order to realize a variety of connection forms by combining a plurality of desks with different shapes, at least the depth dimensions of the desks should be made 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.

An example of a mode in which the effects of the present invention are particularly noticeable is when the top plate and side plates are made of wood.

[Function] With such a connecting structure, when the fasteners are removed from the lower surface of the rain top plate, the connecting plate is pulled out from the slit, and the top plates are separated, they can be used 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 to see the angle of view of the human eye, and
Even if it's in your field of vision, it won't feel too strange because it's in the same position as the joint. 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.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 5.

As shown in Fig. 1, the connection structure of this desk consists of a top plate 2,
The same desk 1□1, each equipped with a side plate 3, a joint 4, and a slit 5, adjoining JR on the left and right, 6 desks IL,
The top plates 2.2 of the IR can be connected to each other via a connecting plate 6.

To explain specifically, the top plate 2 has the following structure as shown in FIG.
It is made of wood with a decorative board 22 attached to the inner surface of a frame-shaped core material 21, and blind nuts 23 are driven into the lower surface 2a near the side edge at two locations on the front and back.

On the other hand, the side plate 3 has a decorative plate 32 on the inner surface of a frame-shaped core material 31.
As shown in FIGS. 2 and 3, the vicinity of the upper end surface 3a is cut at a constant width along the outer periphery, and the area between the upper end surface 3a and the outer surface 3b, and A step portion 34 is formed between the upper end surface 3a and the front end surface 3c. Also,
As a result, a groove 36 is cut out in the thin upper end portion 35 at a position corresponding to the blind eye nut 23 in the assembled state, and this groove 36 is continuous with the step portion 34.

Then, with the side end surface 2b of the top plate 2 and the outer surface 3b of the side plate 3, as well as the front end surface 2c of the top plate 2 and the front end surface 3c of the side plate 3, aligned flush with each other, the bottom surface 2a of the top plate 2 is and side plate 3
The upper end surface 3a of the dowel 7 is bonded to the upper end surface 3a of the dowel 7 with an adhesive applied thereto.

As shown in FIG. A joint 4 having the outer periphery of the upper end portion 35 as the joint bottom is formed between the groove 36 and the lower surface 2 of the top plate 2.
A slit 5 that extends horizontally from the joint bottom in the thickness direction of the side plate 3 and communicates with the inner surface 3d of the side plate 3 is formed between the joint and the side plate a.

As shown in FIGS. 1 and 4, these desks I
The side end surfaces 2b of L and IR are brought into close contact with each other and adjacent to the left and right,
Connecting plate 6 with bolt insertion holes 6a at both ends is attached to one desk I.
Insert it through the slit 5 of R(li,) and insert it into the other desk IL.
(IR), and insert the bolt 8 into the bolt insertion hole 6a of the connecting plate 6 to correspond to the machine IL, J.
The top plates 2.2 are connected to each other by being fixed to a blind nut 23 provided on the R top plate 2 from the lower surface 2a side.

With such a connection structure, when the bolts 8 are removed from the lower surfaces 2a of both top plates 2, the connection plates 6 are pulled out from both slits 5, and the top plates 2 are separated, each desk IL and IR can be connected independently. becomes possible to use. In this state, as shown in FIGS. 1 and 5, the desk IL11R
The joint 4 is exposed on the side of the joint, and the slit 5 is opened at the bottom of the joint, but the joint 4 itself is originally useful for improving the aesthetic appearance of the desk, and the slit 5 is placed at the bottom of the joint. Because of this position, it does not come into the human visual field angularly (and even if it does, it is in the same position as the joint 4, so it does not feel so strange.For this reason, the conventional connection Compared to structures where bolt insertion holes are unnaturally opened in places that should be flush with each other, the unsightliness can be significantly reduced.

In addition, with this configuration, when the six IL%IR units are used alone, there is no need to cover the slit 5 with a resin cap or the like, so there is no need for troublesome management of small parts.

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, it is effective to provide at least six desks with the same depth dimension so that the desks can be connected in various combinations. Alternatively, one desk may be a side table-shaped desk with a larger depth than the other desk.

Furthermore, the top plate and side plates may be made of steel or the like. However, whereas steel products can be processed in relatively complex ways, and other connection structures can be used as a means of solving the problem, wooden products are difficult to process in complex ways, and conventionally Considering the fact that large-scale machining parts such as recesses and bolt insertion holes had to be provided as shown in FIGS. 6 to 8, the present invention can also solve these problems at the same time. This can be a particularly suitable application target. In addition, the cross-sectional shapes of the joints and slits 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 one adjacent desk can be reliably connected to each other by the connection plate, and when the connection plate is removed and six desks are used alone. In addition, the slit into which the connecting plate was inserted opens at the bottom of the joint where it is not noticeable, so it has almost no effect on the appearance, and there is no need to cover the slit with a resin cap, etc., which eliminates troublesome small items. The effect of being freed from managing parts can be obtained.
