Description

  The present invention relates to a table in which a top plate is mounted on a plurality of legs, and more particularly to an improvement in the mounting structure of the top plate.

Many work tables used in offices such as offices have a structure in which a top plate is attached to a plurality of legs via a support bracket (for example, Patent Document 1 and Patent Document 2). reference).
Moreover, the thing of the structure which connected several legs with the crosspiece via the connection member in the vicinity of the upper end part is also proposed (for example, refer patent document 3).
JP-A-5-285013 (FIG. 1) JP-A-7-222625 (FIG. 7) JP 2001-169832 A (FIGS. 2 and 3)

  However, in the conventional techniques described in Patent Document 1 and Patent Document 2, since the legs are not connected to each other and the top board is supported in an independent state, sufficient mounting strength of the top board can be obtained. If the table is shaken, it is difficult to attenuate the shake. In order to solve this problem and secure the mounting strength of the top plate, it is necessary to enlarge the support bracket and use a high-strength one. In this case, the cost increases and the appearance also deteriorates.

  In the conventional technique described in Patent Document 3, since the connecting member is fixed to the upper end of the leg by welding, there is a problem that it takes time and labor and processing / assembly and cannot be applied to a wooden leg. is there.

  Others have screw holes and engagement holes on the legs to screw or engage the connecting member and support bracket, but the connection strength is sufficient by simply engaging and screwing. Is difficult to obtain.

  In view of the above-mentioned problems of the prior art, the present invention can stably and firmly support the top plate by increasing the mounting strength of the cross rail and the support bracket to the legs. Another object of the present invention is to provide a table that can reduce assembly man-hours and costs.

According to the present invention, the above problem is solved as follows.

(2) In the above item (1), the vertical dimension of the attachment part of the connecting member fixed to the end face of the horizontal beam is made larger than the vertical dimension of the horizontal beam, and screws are inserted into the upper and lower ends. A fixing hole that can be fixed is provided.

(3) An engagement groove having a projecting piece that opens outwardly and protrudes inward opposite to the opening edge portion is provided on the outer peripheral surface of the plurality of legs that support the top plate. In the table connected with the horizontal beam, the upper plate part of the support bracket having an L-shaped cross section is brought into contact with the upper end surface of the leg, and the side plate part hanging from the side edge of the upper plate part is connected to the end surface of the horizontal beam. They are sandwiched between members and fastened by fastening means, and the connecting members are fixed to the legs, and the top plate is mounted on the upper plate portion.

(4) In the above item (3), the upper plate portion of the support bracket is fixed to the upper end surface of the leg with a screw.

(5) In the above item (3) or (4), an engaging protrusion is provided on the surface of the connecting member facing the horizontal rail, and the engaging protrusion is formed on the side plate of the support bracket. Fit into the engagement hole.

(6) In any one of the above (3) to (5), a fitting protrusion having a width substantially the same as the width of the engaging groove of the leg is formed on the surface of the connecting member facing the leg. The connecting protrusion is fixed to the leg by fitting the mating convex portion into the engaging groove.

(7) In the above item (5) or (6), an attachment hole for screwing the screw into the female screw hole of the leg is formed in the engaging convex portion of the connecting member, and at least one of the upper and lower sides of the horizontal rail A concave groove facing in the longitudinal direction is formed on one surface, and the engagement protrusion is positioned in the concave groove, whereby a screw is inserted into the mounting hole from the concave groove, and the female screw hole of the leg is inserted. Screw together.

According to the present invention, the following effects can be achieved.
(a) According to the first aspect of the present invention, the upper plate portion of the support bracket is fixed to the upper end surface of the leg, and the side plate portion is fixed by being sandwiched between the side surface of the leg and the end surface of the horizontal rail. The support bracket is firmly fixed, and the mounting strength of the top plate attached thereto is increased.
Further, it is not necessary to enlarge the support bracket or use a high-strength one, so that the cost can be reduced.

  (b) According to the invention described in claim 2, since the holding area of the side plate portion of the support bracket is increased, the mounting strength of the support bracket is further increased, and the workability when being fixed to the side plate portion of the support bracket is improved. It becomes good.

(c) According to the invention of claim 3, since the side plate portion of the support bracket is held between the end face of the horizontal beam and the connection member, the connecting member, the side plate portion, and the horizontal beam are fixed. In addition, the connecting member, the support bracket and the crosspiece are integrally and firmly connected, and the top plate can also be firmly supported.
Moreover, the cross-sectional shape of the leg can be freely selected by simply changing the shape of the attachment surface of the connecting member with the leg.

  (d) According to the invention of claim 4, the mounting strength of the support bracket to the leg is further increased.

  (e) According to the invention described in claim 5, the support bracket can be firmly and accurately positioned and attached between the connecting member and the cross rail.

  (f) According to the invention described in claim 6, the connecting member can be firmly and accurately positioned and attached to the leg.

  (g) According to the invention described in claim 7, since the engaging convex portions of the connecting member are located in the concave grooves of the horizontal rail, there is no possibility that they are relatively displaced laterally, and the concave portions are recessed. A screw can be easily inserted into the female screw hole of the leg by inserting a screw from the groove into the mounting hole of the engaging convex portion.
