Next, the operation of this embodiment will be described.

In this furniture T with a flap top plate, the usage posture (U) in which the top plate 2 is almost horizontal and the top plate 2 stand up by operating the lever-type flap operation operation unit 630 as in the conventional one. The flip-up posture (F) can be selectively taken. When the top plate 2 is in the working posture (U), the caster interlocking member 13 is moved to the final retracted position (B) by the force of the spring S2 as shown in (a) of FIG. 14 and (a) of FIG. It is held, and the first and second casters 4 and 5 are in the wheel locked state (L). In other words, the left and right leg bodies 1A and 1B are maintained in the braking state, respectively. When the top plate 2 is flapped from this state, the lower surface 2a of the top plate 2 comes into contact with the planar cam surface 32b of the interlocking cam 32 during the flap operation, and then the top plate 2 and the interlocking cam 32 Are united and rotate around the axis to reach the flip-up posture (F) shown in FIG. At that time, the interlocking cam 32 rotates counterclockwise in the figure together with the top plate 2, and the vertically interlocking shaft 33 rises accordingly. As a result, the caster interlocking hinge 36 rotates around the hinge support shaft 30, and the drive pin 38 of the caster interlocking hinge 36 rotates forward. When the drive pin 38 rotates forward, the movement of the drive pin 38 is transmitted to the caster interlocking member 13 via the cam receiver 39, and the caster interlocking member 13 resists the urging force of the spring and is in the final retracted position ( Slide and move from B) to the most advanced position (Z). By this movement, the operating portions 46 and 56 of the first and second casters 4 and 5 move forward, and the lock bodies 45 and 55 of the casters 4 and 5 descend to switch to the wheel unlocked state (N). Therefore, the legs 1A and 1B, which were in the braking state, are automatically put into the non-braking state simply by flipping up the top plate 2, and can be freely moved. When the top plate 2 is returned from the flip-up posture (F) to the original usage posture (U), the operation opposite to the operation described above is performed, and both the legs 1A and 1B are in the braking state again.

In such a usage state, when it is desired to temporarily release the braking state of the legs 1A and 1B without flipping up the top plate 2, the operation buttons 71 of the temporary release operation units 7A and 7B provided on the top plate 2 are provided. May be pressed upward. Since this pressing operation can be performed simultaneously by grasping the used edge x or the side edge z of the top plate 2, the unlocking operation and the operation of grasping the edge of the top plate 2 and moving the whole are continuously performed. It can be carried out. That is, when the operation button 71 is pressed upward, the upper end edge of the operation button 71 slides into contact with the inclined cam surface 81a of the slider 81, and the ascending operation of the operation button 71 causes the slider 81 to slide in the counter-use edge y direction. Will be converted. When the slider 81 slides in the counterclockwise edge y direction, this operation is transmitted to the outer periphery of the interlocking cam 32 via the front-rear interlocking shaft 82, and the interlocking cam 32 is rotated counterclockwise in FIG. 14 (b). Move. As a result, even though the top plate 2 is in the use posture (U), the vertical interlocking shaft 33 moves upward due to the rotation of the interlocking cam 32, the caster interlocking member 13 advances, and the casters 4 and 5 move forward. The wheel locked state (L) is switched to the wheel unlocked state (N). Since this switched state is maintained while the operation button 71 is pressed, the entire furniture T with the flap top plate is temporarily held while pressing the operation button 71 while holding the top plate 2. It becomes possible to move to.

In this embodiment, since the temporary release operation portions 7A and 7B are provided in the vicinity of the corner portion where the used edge x and the side edge z of the top plate 2 intersect, the used edge x side is also provided. The above-mentioned operation can be performed reasonably from the side edge z side as well. Moreover, in this embodiment, such temporary release operation units 7A and 7B are provided on both the left and right sides of the top plate 2, and can be integrally rotated with the left and right interlocking cams 32 engaged with the front-rear interlocking shaft 82. Since the interlocking drive shaft 31 is connected by the caster lock operation interlocking beam 93 as described above, the wheel lock state (L) is temporarily set by applying an operation to either the left or right temporary release operation unit 7A or 7B. Can be released as a target.

As described above, in the present embodiment, since the engaging portions that engage with the outer surface 12a of the leg columns 12 are provided at both left and right ends of the curtain plate M, even if the curtain plate main body M1 is thinned, the engagement portions are provided. Due to the presence of the joint, the curtain plate M looks thick. Therefore, it is possible to reduce the weight without impairing the profound feeling of the appearance. Further, since both ends of the curtain plate M engage with the left and right leg columns 12 in the flip-up posture (F), the movement of the curtain plate M can be suppressed. Further, a design that can be expected to increase the rigidity of the entire table in the flip-up posture (F) becomes possible.

In the present invention, any configuration of the legs may be adopted. However, as in the above-described embodiment, the leg body includes a base extending back and forth and a leg strut erected on the base, and the outer surface of the leg strut is the outer surface of the base. The width dimension in the left-right direction of the curtain plate can be set as large as possible as long as it is erected on the base by shifting it outward so as to be substantially flush with each other.

In addition, the engaging portions formed on the left and right ends of the curtain plate are not limited to those using caps attached to the left and right sides of the curtain plate main body as in the above-described embodiment, and the engaging portions with the curtain plate main body. Any configuration may be adopted, such as one that integrally forms with.
