There is one described in JP-A-8-87538. The structure of the rotating part of the top plate in these lighting bureaus is, for example, as shown in FIGS. That is, the hinged top plate 104 is rotatably fixed to the front end of the fixed top plate 102 fixed in the desk body 101 by the hinge 103. Below the rotating top plate 104, a moving member 109 in which a trochanter 108 attached to an inner surface of a side plate 107 of the desk main body 101 is slidably fitted on a rail 106 fixed to both side surfaces 105. Is attached so as to be slidable forward from the desk body 101. Further, a drawer 110 is slidably provided on the moving member 109. The upper end of the connecting rod 111, which is formed in a substantially L-shape or a substantially L-shape as shown in the figure, is formed between the rotating top plate 104 and the moving member 109 at both sides thereof. Rotating shaft 111a on the side of
And the lower end of the connecting rod 111 is rotatably fixed to the side surface 105 of the moving member 109 by the rotating shaft 111b, and the rotating top plate 104 is rotated forward. The pulling-out operation and the sliding and pulling-out operation of the moving member 109 forward are linked to each other.
In other words, in a state where the rotating top plate 104 is rotated forward and pulled out, the lower surface of the rotating top plate 104 is supported in a substantially horizontal state by the moving member 109 which is slid forward and pulled out from the desk body 101. In addition, when the rotating top plate 104 is stored in the desk main body 101 in an upright state, the moving member 109 is also stored in the desk main body 101 accordingly.

[0003]

However, in the above-described conventional rotating structure of the top panel of the lighting bureau, as shown in FIG. 5, the rotating top panel 104 is pivotally pulled out from the upright state. When the moving member 109 is slid and pulled out forward from the desk body 101, the intermediate bent portion 111c of the connecting rod 111, which interlocks and connects the rotating top plate 104 and the moving member 109, projects downward. Rail 1 provided on the side surface 105 of the moving member 109
06, the finger may be pinched between the connecting rod 111 and the rail 106. Further, when the rotating top plate 104 is pivotally pulled out forward, the moving member 10 which is slid forwardly pulled out of the desk body in conjunction with this.
Since the connecting rod 111 fixed to the side surface of the projection 9 protrudes greatly from the desk main body 101, the appearance is not very favorable. Moreover, since the conventional connecting rod has a relatively long length, the supporting state of the top plate is not always stable.

In view of the above problems, the present invention provides a lighting bureau in which a rotating top plate and a moving member that supports the rotating top plate are connected in an interlocked manner.
A finger is provided between a connecting rod that connects the rotating top plate and the moving member when the rotating top plate is pulled out, and a rail or the like that slidably supports the moving member with respect to the desk body. There is no danger of pinching, etc., and the length of the connecting rod is relatively short so that the drawn-out top plate can be stably supported without rattling, and the connecting rod does not protrude greatly from the desk body, It is intended to provide a visually appealing lighting bureau.

[0005]

A lighting bureau according to the present invention for achieving the above object has a rotating top plate rotatably mounted on a desk body, and a lower part of the rotating top plate. A moving member slidably and withdrawn from the desk body to the front, and a connecting rod having one end rotatably fixed to the rotating top plate and the other end rotatably fixed to the moving member. In the lighting bureau in which the pivoting and pulling-out operation of the pivoting top and the sliding and pulling-out operation of the moving member are interlocked with each other, the pivoting top is set in a substantially vertical state as the connecting rod. The vertical portion along the side surface of the rotating top plate in a state of standing up, a horizontal portion along the side surface of the moving member, and an inclined portion provided between the vertical portion and the horizontal portion , and, The horizontal part compared to the vertical part
It is formed short .

[0006]

In the lighting bureau according to the present invention as described above, when the rotating top is pivotally pulled out to the front of the desk main body, the moving member interlockingly connected to the rotating top by a connecting rod. Is slid out to the front of the desk body to support the rotating top plate in a substantially horizontal state. When the rotating top is stored in the desk body in an upright state, the moving member is also stored in the desk body in conjunction with the rotating top. At this time, when the top plate is erected in a substantially vertical state, the connecting rod includes a vertical portion along the side surface of the rotating top plate, a horizontal portion along the side surface of the moving member, and the vertical portion and the horizontal portion. And the rotating top plate is pivoted forward from the desk body.
To change the orientation from horizontal to vertical.
The horizontal part from the vertical direction to the horizontal direction at the same time.
Because it is formed shorter than the vertical part to be changed ,
When the rotating top board is pivotally pulled out from the desk body forward, the connecting rod has an inclined portion between a vertical portion and a horizontal portion in a substantially horizontal state, and a horizontal portion that has turned in the vertical direction. Short form
With this configuration, the bent portion of the connecting rod does not protrude significantly downward, and the connecting position between the connecting rod and the moving member can be provided relatively behind and above the moving member. The length of the connecting rod may be short.
