[0001]

[Industrial applications]

 The present invention relates to a so-called writing bureau in which a top plate is rotatably provided upward and can be stored in an upright state when it is not needed.

[0002]

[Prior art]

 Conventionally, as this type of writing bureau, there are those described in, for example, Japanese Utility Model Publication No. 57-330 and Japanese Utility Model Publication No. 58-87538. The structure of the rotating part of the top plate in these writing bureaus is as shown in FIGS. 5 and 6, for example. That is, the rotating top plate 104 is rotatably fixed to the front end portion of the fixed top plate 102 fixed inside the desk body 101 by the hinge 103. Further, below the rotating top plate 104, a rotator 108 attached to an inner surface of a side plate 107 of the desk body 101 is slidably fitted in a rail 106 fixed to both side surfaces 105. 109 is attached to the desk body 101 so as to be slidably pulled out forward. Further, a drawer 110 is slidably provided on the moving member 109. Between the rotary top plate 104 and the moving member 109, the upper ends of the connecting rods 11 1 formed in a substantially V-shape or L-shape as shown in the drawing are located at both side positions thereof. 104 is rotatably fixed to the side surface of 104 by a rotation shaft 111a, and the lower end of the connecting rod 111 is rotatably fixed to the side surface 105 of the moving member 109 by a rotation shaft 111b. It is configured such that the forward pivoting pull-out operation of the top plate 104 and the forward sliding pull-out operation of the moving member 109 are interlocked with each other. That is, when the rotary top plate 104 is pivotally pulled out forward, the lower surface of the rotary top plate 104 is supported in a substantially horizontal state by the moving member 109 slidably pulled out forward from the desk body 101. In addition, when the rotating top plate 104 is housed in the desk body 101 in a standing state, the moving member 109 is also housed in the desk body 101 accordingly.

[0003]

However, in the table top rotating structure in the conventional lighting bureau as described above, as shown in FIG. 5, the table top 104 can be rotated and pulled forward from the standing state. When the moving member 109 is slid out and slid out from the desk body 101, the intermediate bending portion 111c of the connecting rod 111, which connects the rotating top plate 104 and the moving member 109, is moved downward. Since it protrudes and tilts so as to overlap the rail 106 provided on the side surface 105 of the moving member 109, there is a risk that a finger or the like may be caught between the connecting rod 111 and the rail 106. Further, when the rotating top plate 104 is rotated and pulled out forward, a connecting rod 111 fixed to the side surface of the moving member 109 which is slidably pulled out from the desk body in conjunction with this is pulled out from the desk body 101. By projecting a large amount forward, it was not very desirable in appearance. Moreover, since the conventional connecting rod has a relatively long length, it cannot be said that the supporting state of the top plate is always stable.

In view of the above problems, in the present invention, in a lighting bureau in which a rotating top plate and a moving member that supports the rotating top plate in a horizontal state are interlockingly connected, the rotating top plate is rotated and pulled out. In doing so, there is no fear of pinching a finger or the like between the connecting rod that connects the rotating top plate and the moving member and the rail that slidably supports the moving member with respect to the desk body. In addition, the length of the connecting rod is relatively short so that the top plate pulled out can be stably supported without rattling, and the connecting rod does not significantly project from the desk body, which is also preferable in appearance. It is intended to provide a writing bureau.

[0005]

[Means for Solving the Problems]

 A lighting bureau according to the present invention for achieving the above-mentioned object includes a rotating top plate rotatably attached to a desk main body, and a sliding drawer that can be slid forward from the main body below the rotary top plate. The movable member attached to the rotary member is attached to the rotary top plate so that one end is rotatably fixed and the other end is rotatably fixed to the movable member. In a lighting bureau in which the rotary pull-out operation of the top plate and the sliding pull-out operation of the moving member are interlocked with each other, in the state in which the rotary top plate is erected in a substantially vertical state as the connecting rod, It is formed of a vertical portion along the side surface of the rotating top plate, a horizontal portion along the side surface of the moving member, and an inclined portion provided between the vertical portion and the horizontal portion.

[0006]

[Action]

 In the lighting bureau according to the present invention as described above, when the rotary tabletop is pivotally pulled out to the front of the desk body, the movable member that is interlocked with the rotary tabletop by the connecting rod is the desk body. It is slid out to the front of and supports the rotating top plate in a substantially horizontal state. Further, when the rotating top plate is stored in a standing state in the desk body, the moving member is also stored in the desk body in conjunction with the rotating top plate. At this time, when the top plate is erected in a substantially vertical state, the connecting rod has a vertical portion along a side surface of the rotating top plate, a horizontal portion along a side surface of the moving member, the vertical portion and the horizontal portion. Since it is formed of an inclined portion provided between the vertical rod and the horizontal portion, the connecting rod is provided with an inclined portion between the vertical portion and the horizontal portion when the rotating top plate is pivotally pulled out forward from the desk body. Is substantially horizontal, the bent portion of the connecting rod does not project greatly downward, and the connecting position between the connecting rod and the moving member can be provided relatively rearward and upward in the moving member. The length of the connecting rod may be short.

【Example】

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a writing bureau A according to the present invention. In the figure, reference numeral 1 is a desk body of the writing bureau A, 2 and 2 are both side plates of the desk body 1, 3 is a drawer cabinet provided at the bottom of the desk body 1, and a desk is provided above the drawer cabinet 3. A rotating top plate 4 which doubles as a door for opening and closing the upper front surface of the main body 1 is provided so as to be rotatable and drawn out to the front of the desk main body 1. The inside of the main body 1 of the rear side is used as a storage space as appropriate although not shown. In addition, in the example shown in the figure, a shelf cabinet 5 is attached to the upper part of the desk body 1. A moving member 6 that supports the rotating top plate 4 drawn out from the desk body 1 in a horizontal state is interlocked with the rotating top plate 4 and the lower drawer cabinet 3. It is provided so that it can be slid forward from the desk body 1.

As shown in FIGS. 2 to 4, the rotatable top plate 4 is rotatable by a hinge 8 at a front end portion of a fixed top plate 7 fixed in the desk body 1 between the side plates 2 and 2. It is fixed. The moving member 6 has a rail 9 fixed to the side surface thereof, and a trochanter 10 attached to the inner surface of the side plate 2 of the desk body 1 is slidably fitted in the rail 9 to slide forward from the desk body 1. The movable member 6 is attached so that it can be pulled out, and a drawer 12 is attached to the moving member 6 so as to be drawn forward.

As shown in FIG. 2, recesses 13 are provided on both sides of the lower portion of the rotating top plate 4 in a stepped state over a predetermined length, and fixing fittings 14 are fixed to the recesses 13. The upper end of the connecting rod 11 is rotatably fixed to the fixing member 14 by a rotating shaft 15. On the other hand, the lower end of the connecting rod 11 is rotatably fixed to a fixing member 16 fixed to the side surface of the moving member 6 by a rotating shaft 17. As shown in FIG. 3, the shape of the connecting rod 11 is such that the vertical portion 11a along the side surface of the rotating top plate 4 and the moving member 6 when the rotating top plate 4 is erected in a substantially vertical state. It is composed of a horizontal portion 11b along the side surface and an inclined portion 11c provided between the vertical portion 11a and the horizontal portion 11b.

In the lighting bureau A according to the present invention configured as described above, when the top plate is not used, the rotating top plate 4 stands substantially vertically on the front surface of the desk body 1 as shown in FIG. It is stored in a raised state, and the front surface of the desk body 1 is closed by the rotating top plate 4. From this state, when the rotary top plate 4 is tilted forward of the desk body 1, the rotary top plate 4 rotates forward around the hinge 8 connected to the fixed top plate 7. Then, as the rotating top plate 4 rotates, the connecting rods 11 attached to both sides thereof rotate about the rotating shaft 15 with the rotating top plate 4, and as a result, the rotating shaft 17 at the lower end. Is pushed forward, and the movable member 6 to which the rotating shaft 17 is fixed is slid forward from the desk body 1 together with the drawer 12 while the rails 9 on both sides are supported by the trochanter 10 of the desk body 1. Move dynamically. Then, as shown in FIG. 4, when the rotating top plate 4 is rotated until it becomes substantially horizontal, the rotating top plate 4 is rotated on the support projection 20 provided on the upper surface of the moving member 6 pulled out from the desk body 1 forward. The lower surface of the top plate 4 abuts, and the top plate 4 is supported on the moving member 6 in a substantially horizontal state.

In the above case, according to the present invention, when the rotating top plate 4 is erected in a substantially vertical state, the rotating top plate 4 and the moving member 6 are connected to each other when the rotating rod 4 is erected in a substantially vertical state. Since it is formed of a vertical portion 11a along the side surface of the moving top plate 4, a horizontal portion 11b along the side surface of the moving member 6, and an inclined portion 11c provided between the vertical portion 11a and the horizontal portion 11b, When the rotating top plate 4 rotates from the upright state shown in FIG. 3 to the state in which it is horizontally supported by the moving member 6 as shown in FIG. 4, the rotating top plate 4 and the moving member are moved. 6, the connecting rod 11 rotates, but the inclined portion 11c in the middle thereof does not project downward, and even when the rotating top plate 4 is supported by the moving member 6 and is positioned in the horizontal state, 11c is positioned in a substantially horizontal state with a predetermined distance from the rail 9. Thus, unlike the conventional connecting rod that is bent and formed in a substantially V shape or a substantially L shape, the middle bent portion of the connecting rod does not largely project downward, and the rail 9 on the side surface of the moving member 6 and the connecting rod are connected. There is no fear of pinching a finger or the like with 11. Moreover, by providing the inclined portion 11c in the middle as described above, the position of the rotating shaft 17 connecting and fixing the lower end of the connecting rod 11 and the moving member 6 is also higher than that of the conventional one in the moving member 6. In addition, since it can be positioned further rearward, even if the movable top 6 is tilted and the moving member 6 is pulled out forward as shown in FIG. Can be shortened, which is preferable in terms of appearance. Moreover, since the entire length of the connecting rod 11 can be made shorter than that of the conventional one, the supporting state of the rotating top plate 4 by the connecting rod 11 can be made more stable. .

[Effect of device]

 As described above, in the lighting bureau according to the present invention, the connecting rod formed by connecting the rotating top plate and the moving member to the rotating top plate when the rotating top plate is erected in a substantially vertical state. It is composed of a vertical portion along the side surface of the plate, a horizontal portion along the side surface of the moving member, and an inclined portion provided between the vertical portion and the horizontal portion. Since the inclined portion is positioned in a substantially horizontal state when it is pulled out, the bent portion located at the intermediate portion of the connecting rod does not greatly project downward unlike the conventional connecting rod, and the inclined portion is not moved to the rail of the moving member. There is no danger of pinching your fingers with the connecting rod. In addition, since the horizontal portion is formed by unfolding the inclined portion from the vertical portion along the rotating top plate of the connecting rod, the rotational connecting position between the connecting rod and the moving member is relatively large. It can be installed on the upper side and relatively on the rear side, and the length of the connecting rod can be short. As a result, the supporting state of the rotating top plate by the connecting rod is stable, and the protruding part of the connecting rod toward the front of the desk body when the rotating top plate is rotationally pulled out is small, which is preferable in terms of appearance.
