As shown in FIG. 5A, the first and second ground bodies 8 and 9 are arranged substantially in series so that the centers thereof are located on or near a common imaginary straight line L0. Specifically, each of the grounding bodies 8 and 9 is a disk-like grounding body 81, 91 having a grip on the outer periphery, and a screw rod 82 extending upward from the central portion of the grounding body 81, 91 And the screw rod 82 of the first ground body 8 is screwed into the female screw hole 7y provided on the lower surface of the tip portion 7b of each leg vane 7 so as to be able to move forward and backward. The screw rod 92 of the second ground body 9 is screwed on the lower nut 612 provided at the lower end of the vertical pipe 61 of each core portion 6 so as to be capable of advancing and retracting.

  The height adjustment range of the first and second ground bodies 8 and 9 is from the state where the first ground body 8 is grounded to the floor surface F and the second ground body 9 is separated from the floor surface F The first ground body 8 is separated from the floor surface F, and the second ground body 9 is set to such a value as to be in contact with the floor surface F. Therefore, according to this setting, all the grounding bodies 8 and 9 can be in contact with the floor surface F. Further, the first ground body 8 is mainly grounded to the floor surface F, and the second ground body 9 is relatively lightly grounded to the floor surface F due to the deflection of the leg vanes 7; It is also possible to adopt an aspect in which the first ground body 8 is grounded to the floor surface F and the second ground body 9 is lifted from the floor surface F.

  If it is a thing of such a structure, the leg 2 of a different form is realizable only by using the leg blade 7 as it is, and making the core part 6 into a thing from which a dimension and shape differ. Therefore, it is possible to cope with various specifications while sharing the main components of the leg blades 7 with each other. That is, since the core portion 6 is a structure mainly composed of a square pipe member which is a general-purpose member, those having different depth dimensions can be relatively easily prepared. On the other hand, the same leg vane 7 can be used for various legs 2 having different depth dimensions, and a mold for molding the leg vane 7 can be one type. . Therefore, it becomes possible to manufacture many kinds of legs 2 relatively easily. In other words, although a new mold is needed to change the leg vane 7 which is a molded body, the core portion 6 made using a general-purpose member relatively easily produces various shapes and sizes. be able to. Therefore, various legs 2 having different shapes and sizes as a whole can be manufactured without preparing a plurality of molds.

Further, even if the legs 2 of various sizes and shapes are realized corresponding to the depth dimension of the top board 1, the leg blades 7 can be used in common, so that the image of the appearance can be unified. The lower extremity space on the use end side is also standardized. In other words, the distance between the user and the core portion 6 of the leg 2 can be kept constant regardless of the depth dimension of the top plate 1. Furthermore, the leg 2 is paired with the first ground contact 8 And at least one second ground body 9 located between the first ground bodies 8 in a substantially series manner, and the first ground body 8 and the second ground body 9 are set high. Since the height can be adjusted, by adjusting the heights of the grounding bodies 8 and 9, it is possible to cope with various lands on the floor surface F, and the load is distributed to the floor surface F. It is possible to freely select the setting to be applied, and the setting to apply loads to the floor surface F intensively through a specific grounding body.

  In addition, the first ground body 8 mainly contacts the floor F, and the second ground body 9 contacts the floor F relatively lightly due to the deflection of the leg vanes 7. Since the height adjustment range of the ground bodies 8 and 9 is set so that it can be taken, bending stress acting on the leg vanes 7 can be reduced, and the leg vanes 7 can be made as thin and light as possible. can do. That is, in a state where no load is applied, as shown in FIG. 6, the height position of the first ground body 8 is a predetermined minute distance d considering the deflection of the leg vane 7 more than the height position of the second ground body 9 When the leg 2 is set low and installed in a state where a load is applied to the floor F, as shown in FIG. 7, the first ground body 8 is grounded to the floor F, and The deflection of the leg vanes 7 also makes it possible to lightly install the second ground body 9 on the floor F. In this way, bending stress acting on the leg vanes 7 can be reduced, and the need for making the leg vanes 7 robust can be reduced.

  When weight saving of the leg vanes 7 is not regarded as the most important, or when the weight of the furniture (table T1) itself is not excessive, the first ground body 8 is placed on the floor F as shown in FIG. It is of course possible to adopt an aspect in which the second ground body 9 is lifted from the floor surface F while being grounded. In this aspect, the load can be concentrated on the floor surface by only the farthest first grounding body 8, so that stable installation is possible.

Furthermore, as shown in FIG. 9, only the second ground body 9 is grounded to prepare for the case where it is necessary to replace the leg vanes 7 with the furniture (table T 1) installed and the first ground body 8. Can be separated from the floor surface F.
