Description

TECHNICAL FIELD The present invention relates to a desk connecting structure preferably used in an office or the like.

[Prior Art] In offices and the like, it is often the case that desks, which are normally used individually for individual work, are grouped together or arranged in a required number so as to be used as reception desks. On the contrary, a plurality of desks that are adjacent to each other may be separated and used again as desks for individual work. Therefore, recently, a connecting structure has been considered in which the top plates or the side plates are detachably connected by a fastener when the desks are adjacent to each other.

FIG. 6 relates to a connecting structure for connecting the top plates together,
The top plate b of the desk a is formed with a concave portion d that opens to the lower surface c side near the side edge, and the bolt insertion hole f is horizontal between the concave portion d and the side end surface e of the top plate b. Has been drilled. Then, when the side end surfaces e of the adjacent top plates b are brought into close contact with each other, the bolt g is inserted into both the bolt insertion holes f,
The top plates b can be connected to each other by screwing nuts h into both the through ends in the recessed portions d.

Further, FIG. 7 relates to a connecting structure for connecting side plates to each other, and a side plate j of the desk i has a horizontal bolt insertion hole k penetrating in the thickness direction. And the adjacent top plate l
In a state where the side end surfaces m of the two desks are in close contact with each other, the bolt n inserted through the bolt insertion hole k of one desk i is penetrated to the outside of the bolt insertion hole k of the other desk i, and in this state, the through end of the bolt n is inserted. The side plates j can be connected to each other by screwing the nut o. Bolt p and nut q shown in FIG.
Has been devised so that they can be screwed together in the bolt insertion hole k in order to improve the appearance.

[Problems to be Solved by the Invention] However, in a desk a adopting the connecting structure shown in FIG. 6, when the bolts g are removed and the desks a are used alone, as shown in FIG. The bolt insertion hole f is exposed at the side end surface e of b, which is unsightly. Also,
Also in the desk i which employs the connection structure of FIGS. 7 and 8, when the bolts n and p are removed and the desk i is used alone, the side plate j has a bolt insertion hole k as shown in FIG. It is exposed, and again it causes the inconvenience of being unsightly. Such inconvenience can be solved to some extent by closing the bolt insertion holes f and k with a resin cap or the like.
These inconveniences have been noticed as offices in recent years have rapidly become more intelligent and require highly sophisticated functional and design for all furniture. It shouldn't be acceptable to the discerning user. Moreover, management of small parts such as resin caps tends to be ambiguous during the period when they are not used, and if the period is long, they are often lost and unusable when they want to be used again.

The present invention aims to effectively solve such problems.

[Means for Solving the Problems] The present invention adopts the following structure in order to achieve such an object.

That is, in the desk connecting structure according to the present invention, desks having a top plate, side plates, joints, and slits are laterally adjacent to each other, and the top plates of the desks are connected to each other via the connecting plate. I am trying. The side plate is 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 side surface of the side plate. A slit is opened in the slit, and the slit extends horizontally in the thickness direction of the side plate from the joint bottom and communicates with the inner surface side of the side plate.The connecting plate has both ends penetrating into the slits of the left and right desks, respectively. I will get it. The connecting plate is penetrated at both ends to the top plate of the corresponding desk by using fasteners from the lower surface side, respectively.

In order to realize a variety of connection modes by combining a plurality of desks having different shapes, at least the depth dimensions of those desks should be unified.

When one desk is attached to the other desk and used, the one desk may be a side table type desk having a larger depth dimension than the other desk.

As a mode in which the effect of the present invention is particularly remarkable, there is a case where the top plate and the side plates are made of wood.

[Operation] With such a connection structure, by removing the fasteners from the lower surfaces of both top plates, pulling out the connection plates from the slits, and separating the top plates from each other, it becomes possible to use them as independent desks. . In this state, joints are exposed on the side of each desk, and a slit is opened at the bottom of the joint, but the joint itself is originally useful for improving the aesthetics of the desk. Yes, because the slits are located at the bottom of the joint, it is difficult for the slits to enter the human visual field angularly.
Even if you are in the field of view, you will not feel a lot of strangeness because it is in the same position as the joint. For this reason, it is possible to significantly reduce the unsightlyness as compared with the conventional connection structure in which the bolt insertion hole is opened at a place that should be flush with the original connection structure. In addition, when such a desk is used, it is not necessary to use a resin cap or the like when each desk is used alone, so that it is not necessary to manage cumbersome small parts.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

As shown in FIG. 1, the connecting structure of the desks includes a top plate 2 and
The same desks 1 _L and 1 _R each having a side plate 3, a joint 4 and a slit 5 are adjacent to each other on the left and right, and the top plates 2 and 2 of the desks 1 _L and 1 _R are connected to each other by a connecting plate 6. It is possible to connect via.

More specifically, the top plate 2 is, as shown in FIG.
It is made of wood in which a decorative plate 22 is attached to the six sides of a frame-shaped core material 21. On the lower surface 2a near the side edges, two front and rear devil nuts 23 are provided.
Has been driven in. On the other hand, the side plate 3 is made of wood in which a decorative plate 32 is attached to six sides of a frame-shaped core material 31, and as shown in FIGS. 2 and 3, the vicinity of the upper end face 3a is along the outer periphery. By cutting with a constant width, a stepped portion 34 is formed between the upper end surface 3a and the outer side surface 3b and between the upper end surface 3a and the front end surface 3c. Further, a groove 36 is cut out at a position corresponding to the demon nut 23 in the assembled state with respect to the thin upper end portion 35 by this, and the groove 36 is continuous with the step portion 34. Then, with the side end surface 2b of the top plate 2 and the outer side surface 3b of the side plate 3 and 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 And the upper end surface 3a of the side plate 3 are joined together via a dowel 7 coated with an adhesive.

As shown in FIG. 1, these desks 1 _L and 1 _R are arranged between the side end surface 2b of the top plate 2 and the outer side surface 3b of the side plate 3, and the front end surface 2c of the top plate 2 and the side plate 3R. Between the front end face 3c and the front end face 3c, a joint 4 having the outer periphery of the upper end portion 35 as a joint bottom is formed, and between the groove 36 and the lower surface 2a of the top plate 2, the joint is formed. A slit 5 is formed which extends horizontally from the bottom of the ground in the thickness direction of the side plate 3 and communicates with the inner surface 3d side of the side plate 3.

Then, as shown in FIG. 1 and FIG.
1 _L , 1 _R side end faces 2b are in close contact with each other and are adjacent to each other on the left and right, and a connecting plate 6 having bolt insertion holes 6a at both ends is attached to one desk 1 _R (1 _L )
Through the slit 5 of the other desk 1 _L (1 _R ) to the outside of the slit 5 and the bolt 8 through the bolt insertion hole 6a of the connecting plate 6 of the corresponding desk 1 _L , 1 _R By attaching to the demon nut 23 provided on the plate 2 from the lower surface 2a side,
It connects each other.

With such a connecting structure, when the bolts 8 are removed from the lower surfaces 2a of the top plates 2, the connecting plate 6 is pulled out from the slits 5 and the top plates 2 are separated from each other, the desks 1 _L and 1 _R are respectively separated. It can be used alone. Then, in this state, as shown in FIGS. 1 and 5, the joint 4 is exposed to the side of the desks 1 _L and 1 _R , and the slit 5 is opened at the bottom of the joint. By itself, it is useful for improving the aesthetics of the desk. Since the slit 5 is located at the bottom of the joint, it is difficult for the slit 5 to enter the human's visual field angularly. Since it is in the same position as 4, it does not feel strange. For this reason, compared with the conventional connection structure where the bolt insertion hole unnaturally opens in a place that should be flush with itself,
It is possible to significantly reduce unsightlyness. Moreover, with such a structure, when each of the desks 1 _L and 1 _R is used alone, it is not necessary to close the slit 5 with a resin cap or the like, so that it is not necessary to manage small accessory parts.

The present invention is not limited to the illustrated example. For example, although the same desks are used for the left and right desks in the above embodiment, the invention can be applied to desks having different shapes. In this case, if at least the depth dimensions of the desks are set to be the same, the desks can be variously combined and connected, which is effective. Further, one desk may be a side table type desk having a larger depth dimension than the other desk. Further, the top plate and the side plates may be made of steel or the like. However, steel and the like can be processed in a relatively complicated manner, and other connection structures can be used as means for solving the problem, while wooden ones are difficult to perform complicatedly, and in the past, it has always been necessary. Considering the situation that a large-scale processed portion such as a concave portion and a bolt insertion hole has to be provided as shown in FIGS. 6 to 8,
The present invention can solve that point at the same time, and can be a particularly suitable application target. In addition, the joint and the cross-sectional shape of the slit are not limited to the illustrated examples, and various modifications can be made without departing from the spirit of the present invention.

[Advantage of the Invention] According to the desk connecting structure of the present invention, the top plates of the adjacent desks can be reliably connected by the connecting plate, and moreover, when the connecting plate is removed and each desk is used independently. Since the slit in which the connecting plate is inserted opens in the joint bottom where the position is not conspicuous, there is almost no effect on the external appearance, and the slit does not have to be covered with a resin cap or the like, which is a troublesome accessory part. The effect of being freed from the management of is obtained.
