DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a bathroom unit supporting leg for supporting a bathroom unit.

[0002]

2. Description of the Related Art Bathroom units used in houses and the like are:
It is important that the floor is properly and horizontally installed at a predetermined height on the floor of the installation site. Therefore, as shown in FIG. 6, for example, a plurality of support legs S (normally 4 to 8) are provided under a steel reinforcing frame F fixed under a bathtub section U with a washing place made of FRP.
The height h1 from the lower end surface of the reinforcing frame F to the lower end of each support leg S is adjusted.

FIG. 6 will be described in more detail. A nut N1 is fixed to a reinforcing frame F assembled with a square steel pipe by welding or caulking, and a fool hole H1 is formed in the reinforcing frame F where the nut N1 is fixed. Sa is a bowl-shaped ground contact leg which is formed in a prone bowl shape, and has a fool hole H2 formed in the center of the top. B is a hexagon bolt
The head Ba is in the grounding leg Sa, and the tip of the male screw portion Bb extends upward through the fool hole H2 and is screwed to the nut N1 fixed to the reinforcing frame F. It penetrates the bored hole H1. A lock nut N2 is screwed into the hexagonal bolt B at a portion below the nut N1.

A nut N3 is fixed to the hexagonal bolt B immediately above the grounding leg Sa by welding or caulking. However, a gap c is provided between the inner surface of the top of the grounding leg Sa and the head Ba of the hexagonal bolt B. When the nut N3 is rotated with a spanner, the male screw Bb of the hexagonal bolt B is turned. With the nut N1 moving forward and backward, the distance h1 between the reinforcing frame F and the floor surface FL is adjusted. Similarly, for all the supporting legs, the reinforcing frame F and the floor surface F
The distance h1 of L is adjusted and locked by the lock nut N2.

In the above-described conventional bathroom unit supporting leg S, the grounding leg Sa is formed so as to be higher in a bowl shape, so that the lock nut N2 and the nut N3 on the grounding leg Sa are formed. There is a disadvantage that the distance h2 is narrow and the adjustable range of the distance h1 between the reinforcing frame F and the floor surface FL is small. Also, when the bathroom unit is moved on the floor by dragging the floor surface with many irregularities or the soft floor surface, the peripheral edge of the grounding leg Sa sticks into or penetrates the floor surface, making the movement extremely difficult. There is. Further, there is another problem that the structure of the screw portion such as the grounding leg Sa and the hexagonal bolt B sandwiching the top of the grounding leg Sa is complicated and the manufacturing cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has a wide adjustable range between the reinforcing frame and the floor surface, and drags the bathroom unit. It is an object of the present invention to provide a bathroom unit supporting leg structure which does not become difficult to be moved by being caught on a floor surface when moving.

[0007]

In order to achieve the above object, a supporting leg structure for a bathroom unit according to the present invention comprises a center portion of an upper surface of a horizontal supporting plate whose peripheral edge is formed obliquely upward in the shape of a dish. A male screw member and a spanner hook member for rotating the male screw member are vertically fixed to the portion, and the tip of the male screw member is screwed into a female screw portion provided on a reinforcing frame supporting a bathtub with a washing basin. A lock nut is screwed into a lower portion of the portion.

In the present invention, even when the female screw is formed by directly threading the female screw on the reinforcing frame, a member having the female screw threaded, such as a nut, may be formed on the reinforcing frame by means such as welding. It may be fixed.

(Operation) A spanner is hung on a spanner hooking member fixed vertically upward on a dish-shaped horizontal support plate having a low height, and the male screw member is rotated to raise the height of the reinforcing frame from the floor surface. Since the distance is adjusted, the distance between the lock nut and the spanner hook member is wider than that in the related art, and the adjustable range of the distance between the reinforcing frame and the floor surface is increased.

In addition, since the peripheral edge of the horizontal support plate is raised at a gentle angle to the edge of the dish, when the bathroom unit is dragged on the floor surface, even if the floor surface has irregularities or steps. The rim can ride on a high part of the floor surface and slide. Further, even if there is a weak portion, the peripheral edge is raised and the entire bottom surface portion receives a load, so that the horizontal support plate is prevented from biting into the floor surface.

The horizontal support plate has a shallower shape than that of the prior art grounding leg, and furthermore, the head of a hexagonal bolt, for example, may be directly welded to the upper surface thereof. Simpler than legs.
