Some of the shelves on the side are linked so that they can be folded, but the back of the shelves is pivotally attached to both legs, and the front and rear middle part is simply connected to the front of the top plate with a hanging support rod When the shelf is not used, there is an inconvenience that when the shelf is not used, a sufficient space for putting the foot can not be secured. Also, since the curtain plate is folded so as to overlap the rear side of the leg, the front and rear thickness at the time of folding is thick, not only the stacking efficiency is poor, but also the curtain plate cannot increase the support strength of the leg. There is such a disadvantage. In addition, this type of folding table has a limitation that the rotation angle of the grounding body is limited in order to keep the tabletop upright even when the top plate is folded. Inherent. In addition, since the grounding body is rotatable, there is also a problem that the grounding body may cause lateral shake due to a structural cause during use.

である。As shown in FIGS. 3 to 5, the curtain plate 8 is disposed between the support rods 3 and 3, and the upper end of the curtain plate 8 is provided at a beam rearward of the pivot portion 11. The rear end of the member 9 is pivotally supported by a support shaft 58 and the lower side surfaces 8A of the curtain plate 8
Guide pins 60 projecting from the inner surfaces of the upper and lower intermediate portions of the support rod 3 are slidably engaged with guide grooves 59 provided along
The curtain plate 8 is folded along the two supporting rods 3 and 3 between the two supporting rods 3 and 3 in conjunction with the upright rotation of the top plate 1 (see FIG. 5). In the present embodiment, the upper end of the curtain plate 8 is pivotally supported by the rear end of the beam member 9, but the upper end of the curtain plate 8 may be pivotally supported by the lower surface of the top plate 1. By arranging the curtain plate 8 between the two support rods 3 and 3 as described above, the curtain plate 8 is accommodated between the support rods 3 and 3 when the top plate 1 is turned upright and folded. Therefore, the front and rear width of the table in the folded state can be reduced, and the stacking efficiency increases,
In addition, a lateral reinforcing effect on the supporting rods 3 is also achieved.

を高めることができる。As described above, the folding table according to the present invention is constructed such that the rear portions on both sides of the shelf disposed between the both supporting rods are pivotally supported on the upper inner surfaces of the respective supporting rods below the pivot portion. A long engaging hole is provided along both side surfaces of the front and rear intermediate portion of the body, and the upper end of the hanging support rod is pivotally supported on the beam member in front of the pivoting portion, and the hanging member is set in front of the pivoting portion. A support pin protruding from the lower end of the support rod is slidably engaged with the engagement long hole, and the support pin is held at both ends of the engagement long hole so as to be held and linked, so that the link is connected. In the normal use condition where the board is in a horizontal state, not only can the shelf be supported horizontally below the top plate, but also the front of the shelf is inclined so that it is close to the bottom surface of the top plate so as not to interfere with the feet It can be supported in the state, and further linked with the vertical rotation of the top plate from the horizontal state to the folded state. It can be folded along the top plate of the rack member between the two support leg 杆間 and both beams member, it is possible to increase the stacking efficiency.
