Further, the front edge of the top plate can be used to some extent without being supported by a costly member such as a suspension rail.

  More preferably, it is desirable that the first engaging portion engages with the first engaged portion to restrict the downward movement of the front edge side of the top plate.

Moreover, the furniture with a top plate according to another configuration of the present invention can slide the top plate back and forth on the structure by sliding the movable roller provided on the top plate back and forth in a horizontal groove provided on the structure. in made by supported, the top plate in the rear sliding position, the second engagement portion is separate from the movable roller provided on the top plate side, the top plate attached to the horizontal groove of the front edge of the structure The upper movement of the top plate is restricted by engaging with a second engaged portion provided on the housing of the fixed roller that supports the lower surface of the front edge.

  In this way, even if a lifting force acts on the front edge of the top plate while the top plate is in the rear slide position, the second engaging portion engages with the second engaged portion, so that Since the upward movement is restricted, it is possible to effectively prevent an excessive external force from acting on the slide support portion. Therefore, it is possible to effectively improve the strength during transportation of furniture with a top plate.

  More preferably, it is desirable that the second engaging portion is engaged with the second engaged portion to restrict the downward movement of the top edge side of the top plate.

  Since the present invention is configured as described above, it provides furniture with a top plate that effectively avoids adverse effects on the slide support portion even when an external force in the vertical direction acts on the front edge of the top plate. It becomes possible to do.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 3, the furniture with a top plate of this embodiment can slide the top plate 2 and the drawer 3, which are moving bodies, on the top plate support 1, which is a structure, independently of each other. It is supported like this.

  More specifically, as shown in FIGS. 4 and 5, the top plate support 1 connects the left and right legs 1a, 1a with a rear horizontal member 11 and an intermediate horizontal member 12, and a front horizontal member. The leg portion 1a has a gate shape in which a pair of support pillars 13 and 13 are connected by a side frame member 14. The rear horizontal member 11 and the side horizontal member 14 have a frame member F1 having a horizontal groove f that continuously opens inward along the longitudinal direction, and the intermediate horizontal member 12 continues to both sides along the longitudinal direction. A frame member F2 having an open horizontal groove f is used. As shown in FIG. 7 and the like, the groove width fx of the horizontal groove f is slightly narrower than the vertical inner dimension FX of the hollow portion formed inside the frame members F1 and F2, and A nut member 8 (see FIG. 18), which will be described later, can be locked on the inner surface.

  The top plate 2 is a thin plate having a thickness dimension of about 10 mm, and two movable rollers 20 as movers are arranged in a horizontal groove f continuously opened inside the side frame member 14 as shown in FIG. The first movable bracket 21 and the second movable bracket 22 are attached to the support shaft of the movable roller 20, and the intermediate portion and the rear edge portion of the top plate 2 are mounted on the top plate mounting surface formed above these movable brackets 21 and 22. Is fastened. Both the movable brackets 21 and 22 hold the horizontal state of the top plate mounting surface by inserting convex portions 21a and 22a provided on a part thereof between the upper and lower edges of the horizontal groove f. As shown in FIGS. 1 and 8, the top plate 2 is slid forward to open the back region 1B of the top plate support 1 upward as shown in FIGS. It is possible to move between a rear slide position 2B (normal use position) that slides backward to close the back area 1B. At that time, the lower surface of the front edge side is supported by the first fixed roller 23 which is a front edge side support provided on the side frame member 14, and the front slide position 2F shown in FIG. 7 and the rear slide shown in FIG. The lower surface on the front edge side of the top plate 2 is backed up between the position 2B. Further, the top plate 2 is attached to a second fixed roller 24, which is an intermediate support body provided with the lower surface of the central portion on the intermediate horizontal member 12, as shown in FIG. 4, in order to prevent bending of the central portion in the width direction. The lower surface of the center part of the top plate 2 is backed up between the front slide position 2F shown in FIG. 9 and the rear slide position 2B shown in FIG. 10 to prevent its bending.

  Accordingly, on the top plate 2, a first latch member 41 for locking to the front slide position 2F shown in FIG. 12 and a second latch member 42 for locking to the rear slide position 2B shown in FIG. And a third latch member 43 for locking to the intermediate slide position 2M shown in FIG. 13, and the top plate 2 is in the state of FIGS. 7 and 8 in the front slide position 2F and the rear slide position 2B. Engaging structures 51 and 52 that restrict the vertical movement of the front edge side of the top plate 2 are employed, and the top plate 2 is in the state of FIGS. 9 and 10 with the top plate 2 at the front slide position 2F and the rear slide position 2B. Restriction portions 61 and 62 for restricting the vertical movement on the rear edge side are provided.

  The latch members 41, 42, 43 are provided at three locations along the depth direction of the top plate 2, and the latch members 41, 42, 43 are forwarded and returned to the outer surface of the intermediate horizontal member 12 at a predetermined movement position. The top plate 2 is brought into contact with a predetermined movement position.

  As shown in FIGS. 11 to 17, these latch members 41, 42, and 43 are in the form of a balance attached around the support shaft m, and the intermediate horizontal member 12 has a first contact perpendicular to the moving direction. In relation to forming a substantially square pipe shape having an upright surface 12a as a contact surface and an upper surface 12b as a second abutting surface parallel to the moving direction, the upright surface in a normal posture elastically biased by a spring 44c. The vertical surface 4a that can face the surface 12a and the downward surface 4b that can face the upper surface 12b, and from the intermediate height of the vertical surface 12a of the intermediate horizontal member 12 below the vertical surface 4a than the vertical surface 12a. An inclined surface 4c that is inclined to a slightly higher position is provided. For example, when the top plate 2 is slid forward, the latch member 41 moves over the upper surface 12b of the intermediate horizontal member 12 while performing the balance operation around the support shaft m along the inclined surface 4c. 12 (a), the latch members 41, 42, and 43 return to the normal posture through the reverse balance operation, so that the upright surface 4a and the downward surface 4b of the latch member 41 are connected to the intermediate horizontal member 12. It is made to contact | abut or adjoin to the standing surface 12a and the upper surface 12b. Then, when receiving a moving force in the direction in which the top plate 2 is pushed in, the latch member 41 moves in a direction in which the contact force between the rising surfaces 4a and 12a and between the downward surface 4b and the upper surface 12b increases. The intermediate horizontal member 12 is stretched so as to hold the latched state of the top plate 2 at the front slide position 2F.

  In addition, the latch release lever 45 described later is operated from this position to bring the latch members 41, 42, 43 into a horizontal posture that does not interfere with the intermediate horizontal member 12 as shown in FIG. Is moved to the normal position through the balance operation at the position where the inclined surface 4c of the latch member 41 gets over the upper surface 12b of the intermediate horizontal member 12, and the slide operation is continued by the following slide operation. 13, the upright surface 4 a and the downward surface 4 b are brought into contact with or close to the upright surface 12 a and the upper surface 12 b of the intermediate horizontal member 12. Therefore, even if it receives a moving force in the direction in which the top plate 2 is continuously pushed after that, the latch member 43 remains in the direction in which the contact force between the rising surface 4a and the rising surface 12a and between the downward surface 4b and the upper surface 12b increases. In order to stretch against the intermediate horizontal member 12, the latched state of the top plate 2 at the intermediate slide position 2M is maintained.

  Furthermore, after operating the latch release lever 45, which will be described later, from this position to bring the latch member latch members 41, 42, 43 into a horizontal position as shown in FIG. 5B, the top plate 2 is slid backward. Then, at the position where the inclined surface 4c of the latch members 42, 43 gets over the upper surface 12b of the intermediate horizontal member 12, the latch members 41, 42, 43 return to the normal posture of FIG. The vertical surface 4a and the downward surface 4b are brought into contact with or close to the vertical surface 12a and the upper surface 12b of the intermediate horizontal member 12. Therefore, even if it receives a moving force in the direction in which the top plate 2 is pulled forward thereafter, the latch member 42 is increased in the direction in which the contact force between the rising surface 4a and the rising surface 12a and between the downward surface 4b and the upper surface 12b increases. However, the latching state at the rear slide position 2B of the top plate 2 is maintained.

  Incidentally, these latch members 41, 42, 43 are accommodated in a latch housing 40x as shown in FIGS. The latch housing 40x is a thin plate that is disposed in a gap of about 10 mm between the top plate support 1 and the top plate 2, and has through holes 40a, 40b, and 40c at a plurality of locations. The latch members 41, 42, 43 that protrude from the thickness only when the top plate 2 is locked to the horizontal member 12 within the thickness of the through holes 40 a, 40 b, 40 c. A transmission member 44 that transmits a lever operating force of the latch release lever 45 described below to the latch member is incorporated. A part of the through hole 40c is a bottomed groove. The latch release lever 45 is incorporated in a latch housing 40y configured separately from the latch housing 40x.

  The latch release lever 45 is attached so as to be rotatable about the vertical axis n, and the transmission member can be operated regardless of which of the operation edges 45a and 45b positioned at the left and right positions on the lower surface of the front edge of the top plate 2. The latch members 41, 42, and 43 are rotated via 44 so that the locked state with the horizontal member 12 can be released. The transmission member 44 includes a rod 44a that moves back and forth in the depth direction as the latch release lever 45 is rotated, and an operating body that scoops the latch members 41 and 43 around the support shaft m when the rod 44a moves rearward. 44b, and a spring 44c that biases the rod 44a forward and offsets the latch release lever 45 to the normal position. 15 (a) → (b), when the actuating body 44b moves rearward, the latch members 41 and 43 are supported by sinking into the tapered force receiving portions 41a and 43a provided integrally with the latch members 41 and 43. A state of scooping up around the axis m is shown. The latch member 42 is attached around the support shaft m in association with a position where the tip 42 b is pushed down by the tip 43 b of the latch member 43, and is configured to operate synchronously with the latch member 43.
