Description of the Related Art In a plurality of desks, counters, tables, and the like, connecting bolts are passed through the top plate in the length direction of the top plate, and the bolts are tightened at both ends. Accordingly, the inventors of the present invention have disclosed a connecting top plate structure in which a leg member for supporting a vertical load applied to the top plate is not provided on the lower surface of the top plate located in the middle, as disclosed in Japanese Patent Application Laid-Open No. 57-96619. It has been proposed as Japanese Patent Publication No. 1-1486, etc., and has since been commercialized and has been well received by users in various fields.

[0003] In the above-mentioned connection top plate, since no leg member is provided below the middle top plate, when forming the top plate connection body, the left and right outside edges of the top plate located on both outer ends are formed. A panel-shaped or modified type leg member is arranged, and this leg member is also fixedly attached to the outer end surface of the side end top plate together with each top plate by the connection bolt.

However, in the above configuration, since the panel-shaped leg members are necessarily attached to the left and right ends of the top plate connector, the planar shapes of the left and right side end surfaces of the top plate connector are not limited. It had to be formed in a straight line according to the form of the leg member. Therefore, when the above-described top plate connecting body is formed on a desk of a free address system, the plane shape of the desk becomes rectangular, and there are panel-shaped leg members at the left and right side edges of the desk. Even if it is a desk of the free address system, a person cannot directly reach the short side of the desk, but can only take a use form in which the person reaches the long side of the desk.

In view of this point, the left and right outer ends of the connection desk using the above-described rectangular top plate connection body, that is, the side where the panel-shaped leg members are located, have the same depth as the top plate connection body. A so-called side desk (or side table) using a semi-circular top plate having a diameter or a rectangular top plate having a long side having the same length as the depth is applied and joined, and the planar shape of the entire top plate is lengthened. There has been provided a connection desk formed in a circular shape or a rectangle larger than the top plate connection body.

[0006] As described above, the connection desk formed so as to have an apparently oblong top plate surface or the like is formed by connecting the left and right outer ends and half of the rectangular top plate connection body when viewed from the plane. Since the upper end surface of the panel-shaped leg member is located between the contact end surfaces of the circular top plate, an uneven joint is formed on the surface of the top plate by the upper surface of the leg member, and the appearance is not preferable only. In addition, there is a problem that the joints become an obstacle in use. Also, when assembling the connection desk, the leg member is attached to the rectangular top plate connection body and assembled, and then the side desk having a semicircular top plate or the like is applied and joined, so that assembling time is also increased. There is a problem.

Although not shown, the end top plate connected to the single-type top plate connection body is formed to have a width corresponding to the depth of the left and right ends of the connection body. This is equivalent to the end top plate C described above.

[0030]

The connection desk of the present invention constructed as described above has the following unique effects as compared with conventional desks of this kind.

The intermediate top plate and the end top plate are connected by a connecting rod penetrating the inside of the intermediate top plate in a state where the side end surfaces of the respective top plates are in direct contact with each other. There is no joint due to different members such as the upper surface of the ceiling, so that not only does the whole look like a top plate formed as a single sheet, but the joints due to different members are not formed at all on the top plate surface. Not only is there no unevenness on the plate surface, the appearance is good, but also the free addressability is improved, so that there is no inconvenience in use.

When the intermediate top plates are joined by direct joining, a coupling fitting having only an intermediate portion formed into an L-shaped cross section is used. Therefore, an L-shaped cross-section formed as an intermediate spacer between the fittings and serving as a spacer. Accordingly, when the intermediate top plates are joined to face each other, the gaps to be formed on the facing surfaces can be uniformly defined, and the L-shaped cross section connects the top plate connecting body to the leg member. Since they act as both positioning keys when they are combined with each other, the assemblability is significantly improved.

Further, when the front side edge shape of the intermediate top plate is formed into a flat concave / convex curved surface, the whole connected body of the top plate forms a wavy concave / convex continuous curve, and accordingly, the left and right ends of this connected body When the end top plate having a curved shape such as a semicircle is arranged and connected to the connection desk, the end top plate is formed as a connection desk having a planar top plate that cannot be seen as a conventional connection desk as a whole, so that the appearance is excellent. In particular, the bulge formed by the convex curved surface formed on the front side of the intermediate top plate has a space due to the bulge portion on the front side even when a desktop type OA device having a relatively large depth is placed on the top plate. Even with a free address type connection desk, there is an advantage that the usability when the OA device is placed is not impaired.

Further, in the intermediate top plate of the oppositely coupled type, a lip-shaped band made of a flexible material is provided between the two rows of wiring duct covers and the two duct covers in the gap between the opposed surfaces.
Even if the desk panel is erected in the length direction of the intermediate top plate on the center of this gap, the wiring of the wiring from the wiring duct cover is not damaged at all, and the desk panel is located between the lower surface and the upper surface of the top plate. Because it is erected with a gap in it,
It does not hinder the attachment / detachment of the duct cover or the insertion / removal of the wiring from / to the lip-shaped band portion, and is convenient in handling the wiring. As described above, the present invention is extremely useful in manufacturing or using a so-called free address type connection desk.
