The above-mentioned leg fitting has the advantage of being able to mount a relatively heavy panel with a simple structure and to adjust the height thereof, There are also points that need to be improved. That is, the up and down movement of the leg fittings is performed by screwing the screws, and the movement interval is exclusively dependent on the screw spacing. Therefore, in order to increase the vertical movement interval as much as possible, it is necessary to increase the vertical interval between the male screw and the female screw, but the processing of the male screw is relatively easy, but the female screw is It is difficult to increase the vertical distance. In particular, it is generally troublesome to form a female screw on the inner periphery of a cylindrical body such as the body. Further, when an internal thread is formed on the inner periphery of the cylindrical body, the thickness must be increased by the amount of the threaded portion, so that the thickness becomes relatively large, and it is difficult to reduce the labor of parts. Becomes Further, the body is usually formed by bending stainless steel or the like and welding the abutting edges, but the hardness of this welded portion is increased, and when forming an internal thread on the inner periphery, cutting is sometimes performed. Blade (bite)
The inconvenience of breaking is also occurring.

Therefore, the present invention proposes a leg fitting which can be manufactured easily while maintaining a simple structure similar to the above-mentioned conventional one, and which can expand the height adjustment range. Is what you do.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a seat having a seat placed on a floor, a body standing upright on the seat, and a panel placement surface at an upper end. A leg having a threaded portion at a lower portion of the panel mounting surface portion, wherein the threaded portion of the leg is screwed into the body portion and the leg is rotated up and down to move the leg up and down. In the above, at the upper end of the body, a separate leg receiving portion to be screwed with the screw portion of the leg is mounted,
The leg receiving portion includes a tubular portion press-fitted into the trunk portion, and a flange formed at an upper end of the tubular portion, and the tubular portion slides on an outer peripheral surface thereof with an inner wall of the trunk portion. A contacting slip surface is formed, and an internal thread is formed on an inner peripheral surface thereof, the female screw being screwed with the screw portion of the leg body, and the flange portion is positioned above an upper end edge of the trunk portion. It is a leg fitting provided in. Still preferably, the slip surface of the cylindrical portion is formed by knurling.

[0007]

The foot metal fitting of the present invention is placed on the floor, and a panel or the like is mounted on the floor. Height adjustment is performed by screwing the panel mounting surface portion of the leg fitting to the lower portion of the panel or the like, and turning the body screwed to the leg while temporarily lifting and gripping the panel or the like. The threaded portion of the leg is screwed with a female screw of the cylindrical portion that is press-fitted into the body, and the body and the seat are moved up and down by rotating the body. The female screw is different from the conventional one, that is, it is not formed on the body part as in the prior art, but is provided on the cylindrical part attached to the body part, so that the interval between the female screws can support the leg The smallest one will be fine. In other words, in the conventional case, the threaded portion of the leg is screwed with the trunk, so that the female screw must be formed in the trunk only for the interval in order to move a certain range in the vertical direction. I had to. Therefore, the amount of movement is equal to the processing range of the internal thread, and since increasing the amount of movement requires increasing the number of female threads,
Its production has been difficult in proportion to the amount of movement. On the other hand, in the case of the present invention, since the condition of the working range of the equal amount internal thread is removed, the production is facilitated, and at the same time, the range in which the height can be adjusted is not restricted by the processing range of the internal thread. It is easy to extend the adjustment range.
