【０００２】
【従来の技術】
従来の事務用机には、天板上に載置したＯＡ機器や照明装置等に接続する給電線や通信線等の配線処理を、体裁よく、簡単に行なえるようにするため、天板の後端、もしくは天板と幕板の上端部との間、または側板の内面等に、配線収容用のダクトを設けたものがある（例えば実開平７−１１１９１６号公報参照）。
【０００３】
【発明が解決しようとする課題】
しかし、従来のものは、天板、配線用ダクト、及び幕板等をそれぞれ別個に脚や袖箱等に取付けていたため、組立てに手間がかかるだけでなく、例えば、天板の後端と幕板の上端部との間にダクトを形成し、その上面にカバーを配設するような場合、天板の後端と幕板との間の寸法精度を出しにくく、カバーをうまく装着できなかったり、天板の上面と幕板の上端との平面性が損なわれたりする。
【０００４】
本発明は、天板を前部部材と後部天板とに分けて前後方向に若干離し、かつ両者を、前部天板の厚さより薄い連結部材により連結することにより、天板自体に横送り用の配線空間を形成し、この天板を脚等に組付けるだけで、横送り配線ができるようにし、もって、上述のような問題点を解決した机等の天板を提供することを目的としている。

The flatness between the upper surface of the top plate and the upper end of the curtain plate may be impaired.
[0004]
In the present invention, the top plate is divided into a front member and a rear top plate, separated slightly in the front-rear direction, and connected to each other by a connecting member thinner than the thickness of the front top plate, thereby laterally feeding the top plate itself. The purpose is to provide a top board for a desk or the like that solves the above-mentioned problems by forming a wiring space for use and enabling horizontal feed wiring only by assembling the top board to a leg or the like. It is said.
[0005]
[Means for Solving the Problems]
According to the present invention, the above problem is solved as follows.
(1) A connecting member is provided at the rear lower part of the rear top of the front top plate. The connecting member is provided with a U-shaped base that is recessed upward so that the central portion is thinner than the thickness of the front top plate. By connecting the rear top plate to the rear so that the upper surface of the rear top plate is flush with the upper surface of the front top plate, a wiring space for lateral feed is provided between the front top plate and the rear top plate. Form.
[0006]
(2) In the above item (1), by connecting the front top plate and the rear top plate with a plurality of connecting members having appropriate spacing in the left-right direction, between two adjacent connecting members, A wiring space for vertical feeding that faces in the vertical direction is formed.
[0007]
