The modesty panel 61 is configured to extend both left/right ends onto the front legs of the left/right leg bodies 1A, and is supported by the top board 2 via coupling elements 86 that move along trajectories deviated from a circular arc track using the main shaft 37 as a center.

Description

  The present invention relates to furniture with a flap top board provided with a curtain.

  Conventionally, the left and right legs with the front legs extending forward from the lower end of the column, and the main legs are arranged on these legs via the main shafts, from the top plate use posture to the flip-up posture around the main shafts. There is known a flap table having a top plate that performs a flap operation and a curtain plate that is supported on the opposite side of the top plate and that operates from the curtain use position to the stowed position in accordance with the flap operation of the top plate. (For example, see Patent Document 1).

  The flap table includes a link stay whose base end is fixed to the counter-use end side of the top plate, a pin-like connecting element provided at the tip of the link stay, and the link element so as to rotatably support the connecting element. And an attachment base provided on the upper end side of the curtain. Then, the movement of the top plate that moves from the top plate use posture to the flip-up posture is changed to the movement that moves from the curtain plate use posture to the storage posture via the link stay, the connecting element, and the mounting base described above. It is done. At that time, the conventional one is restricted so that the connecting element passes through the circular arc track centering on the main axis.

  By the way, in such a flap table, there is a demand for increasing the vertical dimension of the curtain plate so as to largely hide the front surface of the lower limb space. However, when the vertical dimension of the curtain plate is increased, the upper surface of the front leg and the lower end of the curtain plate in the stowed position tend to interfere with each other. When the lower end side of the curtain plate comes into contact with the leg, an excessive force is applied to the link stay that connects the curtain plate and the leg, and in this state, the flap table itself is moved or an impact is applied from the outside. If there is an added, there is a risk that the lower end of the curtain plate in contact with the leg will be damaged or deformed.

  Under such circumstances, there has been a problem that the vertical dimension of the curtain must be shortened.

As shown in FIGS. 17 and 18, the long hole 87 has a central portion 871 for stably holding the connecting element 86, and the first curtain plate 61 extends upward from the central portion 871 so that the first curtain plate 61 is in the curtain plate use posture (U). And a floating portion 872 for allowing the connecting element 86 to reciprocate in the vertical direction when moving between the center portion 871 and the first curtain plate. And a lock portion 873 for prohibiting the 61 from moving more than a certain amount in the direction away from the column 11.

  As shown in FIGS. 5, 6, 10 to 14, 17, and 18, the curtain plate side bracket 85 has a clearance that allows the connecting element 86 to move freely in the thickness direction of the curtain plate 61 on the tip side. A hole 88 is provided. As shown in FIGS. 17 and 18, the escape hole 88 has a central portion 881 that stably holds the connecting element 86 by gravity acting on the first curtain plate 61, and extends obliquely downward and rearward from the central portion 881. A rear half portion 882 for allowing one curtain plate 61 to move in a direction away from the column 11, and the first curtain plate 61 extending from the central portion 881 obliquely downward and forward and away from the top plate 2. And a first half portion 883 for allowing movement in the direction.

  As shown in FIGS. 5, 6, and 10 to 14, the connecting element 86 passes through the escape hole 88 and the long hole 87 so as not to fall off. Therefore, the connecting element 86 can be appropriately moved along the long hole 87 and the escape hole 88 and is moved along a trajectory deviating from the arc trajectory centered on the main shaft 37. . That is, the connecting element 86 has a pin shape that connects the top plate 2 and the curtain plate 61 so as to be rotatable and slidable.

  The link stay 82 is of a free end type as shown in FIGS. 1, 3, 5, 7, and 10 to 14, and one end is provided near the lower edge of the first curtain plate 61. The other end is pivotally attached to the support 11 of the legs 1A and 1B. The length of the link stay 82 is such that the first curtain plate 61 hangs substantially vertically in the curtain use posture (U), and the lower edge of the first curtain plate 61 is the leg 1A in the storage posture (F). , 1B so as to be located very close to the front leg 13.

  As shown in FIGS. 5, 6, and 10 to 14, the hinge 83 is for supporting the second curtain plate 62 on the lower surface 21 of the top plate 2 so as to be pivotable in the front-rear direction. .

  Next, the operation of this embodiment will be described.

  In the top plate use posture (U), as shown in FIGS. 1 to 5, 7, 10, and 13, the top plate 2 is held horizontally, and the lock claw 33 is moved to the first engagement portion 301. And the top board use posture (U) is maintained. From this state, when the operating lever 330 is pivoted upward to disengage the lock claw 33 from the first engaging portion 301 and the use end x side of the top plate 2 is lifted, the top plate 2 causes the main shaft 37 to move. Rotates as the center. At that time, after passing through the intermediate stage as shown in FIG. 11, the lock pawl 33 is moved to the second engaging portion 302 in the flip-up posture (F) as shown in FIGS. 6, 8, 12, and 14. Is engaged and locked.

  In the top plate use posture (U), the first curtain plate 61 is maintained in a state of hanging substantially vertically by the cooperation of the suspension mechanism 81 and the link stay 82. On the other hand, the second curtain plate 62 is suspended by its own weight and its lower end is in contact with the inner surface of the upper edge of the first curtain plate 61. It should be noted that a magnet catch (not shown) may be provided at the contact portion of the first and second curtain plates 61 and 62 for maintaining the contact state of both of them by magnetic force.

  When the top plate 2 is turned to the flip-up posture (F) as described above from this state, the second curtain plate 62 is moved to the first curtain plate as shown in FIG. It is pressed by the upper edge of 61 and rotates to the top plate 2 side, and finally turns around to the front side of the first curtain plate 61 as shown in FIG. The movement of the first curtain 61 when such an operation is performed is as follows. That is, in the top plate use posture (U), the connecting element 86 is positioned at the lower end that is the central portion 871 of the long hole 87 of the top plate side bracket 84 and the central portion 881 of the escape hole 88 of the curtain plate side bracket 85. The first curtain plate 61 is suspended and supported by the top plate 2 in a state of being positioned at the position. When the top plate 2 is rotated from the top plate use posture (U) to the flip-up posture (F) direction, the first curtain plate 61 is lowered and retracted while maintaining this state. At that time, in the final operation region from the vicinity of the flip-up posture (F) to the jump-up posture (F), the lowering degree of the first curtain plate 61 is suppressed by the action of the link stay 82, and the flip-up is performed. When the posture (F) is reached, the lower end of the first curtain plate 61 comes close to the upper end of the front leg 13. When the final operating region is reached, the connecting element 86 supporting the first curtain plate 61 moves up relative to the top plate side bracket 84. For this reason, the trajectory deviates from the arc trajectory centered on the main shaft 37. Thus, the connection element 86 once moves to the upper side of the floating portion 872 of the long hole 87 and then moves back to the central portion 871 until it reaches the flip-up posture (F).

  When the above operation is performed, as shown in FIG. 17, if there is an interposition F such as a finger or a hand between the first curtain plate 61 and the support 11, the first curtain plate 61. The forward biasing force will work. Therefore, it is possible to suppress the connection element 86 from moving from the central portion 881 to the rear half portion 882 of the escape hole 88 of the curtain plate side bracket 85 and applying a large clamping pressure to the inclusion F. At this time, the connecting element 86 has shifted to the lock portion 873 of the long hole 87 of the top plate side bracket 84.

  On the other hand, as shown in FIG. 18, when an inclusion F such as a finger or a hand exists between the first curtain plate 61 and the top plate 2, a rearward biasing force is applied to the first curtain plate 61. Will work. Therefore, it is possible to suppress the connection element 86 from moving from the central portion 881 of the escape hole 88 of the curtain plate side bracket 85 to the front half portion 883 and applying a large clamping pressure to the inclusion F. When the inclusion F is present near the upper end portions of the top plate 2 and the first curtain plate 61, the first curtain plate 61 not only escapes backward as described above, but also the second curtain plate 62. Is rotated forward, and a large clamping pressure is prevented from acting on the inclusion F. At this time, the connecting element 86 has shifted to the lock portion 873 of the long hole 87 of the top plate side bracket 84.

<Effect of this embodiment>

A top plate 2 which is disposed above the main shaft 37 and flaps around the main shaft 37 from the top plate use posture (U) to the flip-up posture (F), and the counter-use end y of the top plate 2 A curtain plate 61 that is suspended and supported on the side and operates between a curtain use posture (U) and a storage posture (F) in accordance with the flap operation of the top plate 2. 61 has left and right ends extending on the front legs 13 of the left and right legs 1A and 1B, and this curtain plate 61 is moved along a track deviating from an arc track centering on the main shaft 37. The top plate 2 is supported via a connecting element 86.

  Thus, since the curtain plate 61 is supported on the top plate 2 by the connecting element 86 that moves away from the arcuate track, the vertical dimension of the curtain plate 61 can be freely designed. That is, as in the present embodiment, if the support location of the curtain plate 61 is set so as not to be lowered too much so as to suppress interference between the upper surface of the front leg 13 and the lower end of the curtain plate 61, The direction dimension can be set large. Therefore, it is possible to increase the concealed area even if the curtain 61 has rigidity, not cloth or the like.

  In particular, in this embodiment, the left and right end portions of the curtain plate 61 extend to the top of the front legs 13, so that the horizontal width dimension of the curtain plate 61 can be increased. Therefore, the curtain 61 can be designed large in the vertical and horizontal directions, and can be concealed over a wide range.

  Further, since the connecting element 86 of this embodiment is a pin-shaped connecting the top plate 2 and the curtain plate 61 so as to be rotatable and slidable, the movement of the connecting element 86 described above with a relatively simple configuration. Can be realized.
