BRIEF SUMMARY
FIELD OF THE ART

This invention relates to a desk in which the top plate and the legs can be assembled and disassembled.


BACKGROUND ART

In prior art desks of this type it is customary to connect right and left legs by cross members, on which a top plate is placed and fixed to them.
In other words, in the prior art desks legs and various types of cross members are combined to form a rigid body, on which a top plate is mounted.
In the prior art the top plate is so designed as to be reinforced by cross members, so that it is apt to be curved or warped unless it is fixed to the cross members at many positions. In addition, unless both the legs are securely fixed to the cross members, it is difficult to give to the body a sufficient degree of rigidity to support the top plate.
Therefore, in the prior art desks, it is customary to use bolts to connect the legs to each other or the top plate to the cross members, so that much time and labor are required for assembly or disassembly.
In offices or the like places many desks of the same standard or design are often connected side by side. To this end it is customary to simply connect the top plates or legs of adjacent desks by using metal fittings. This arrangement leads to a problem that the legs of the connected adjoining desks stand side by side and become so bulky as to reduce usability, with many of the component parts being used redundantly and with a difficulty of making the top plates flush with each other.
In addition to the above inconvenience, in modern offices various office machines are installed which are provided with much wiring. In the previously mentioned conventional desks wires or cables are exposed on the top plate and hang down onto the floor to extend thereon. This is not only unsightly but also obstructive to persons walking on the floor, and if the wires on the floor are trod on or hooked by feet, they are likely to be cut or broken.
The object of the invention is to solve the above problem once and for all.


DISCLOSURE OF THE INVENTION

To attain the above object, the invention has adopted the following construction.
The desk of the invention is provided with a top plate, legs, tapered engaging means, and claw-type engaging means. The top plate has rigidity. Each of the legs is provided with an upwardly facing surface adapted to be in contact with the under surface of the top plate and at the top end thereof with an arm extending along the front edge of the top plate. The tapered engaging means comprises a concavely tapered surface formed in either one of the front edge of the top plate and the arm of each leg, and a convexly tapered surface formed on the other. The concavely and convexly tapered surfaces can be brought into contact with each other by sliding the leg relative to the top plate toward the user's side. The claw-type engaging means comprises bent claws formed on either one of the under surface of the top plate and the upper surface of each leg and claw-receiving holes formed in the other. The claws are brought into engagement with the holes formed by putting the claws into the holes and sliding the leg relative to the top plate toward the user's side. Under the condition that the engaging means are engaged, the previously described arm is fixed by fasteners to the front edge of the top plate.
With the above basic construction, the under surface of the top plate is put on the upwardly facing surface of the leg, and the leg is slid relative to the top plate toward the user's side, whereupon the claws of the claw-type engaging means engage the claw-receiving holes, and at the same time the arm of the leg approaches the front edge of the top plate until the convexly tapered surface of the tapered engaging means enters the concavely tapered surface thereof. Under the condition, the arm is secured by a fastener to the top plate, whereupon the convexly tapered surface closely contacts the concavely tapered surface so that the arm is fixed to the top plate. Since the arm is rigidly fixed to the leg, the secure connection of the ar
