Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed on the bottom of a bath tub to make it easier for a person, such as the elderly or the disabled, to enter or leave the bath tub or to stand and sit in the bath tub, and to maintain a bathing posture. The present invention relates to a bathtub having a suction cup on a leg portion for facilitating ease of use.

[0002]

2. Description of the Related Art FIGS. 5 to 6 show a first example of a conventional bathtub table having a suction cup on a leg portion. This bathtub table 100 has a seating surface 1
01 and a leg 102. A suction cup 103 with a bolt is attached to the lower end of the leg 102 by screwing a bolt 103a attached to the upper end thereof.

FIGS. 7 to 9 show a second example. The bathtub table 200 includes a seat surface 201 and a leg pipe 202. A suction cup 203 is attached to the lower end of the leg pipe 202 by press-fitting the lower end of the leg pipe 202 into a leg pipe insertion groove 203 a provided at the upper end of the suction pipe 203.

[0004]

In the bathtub of the first example, it is necessary to insert a bolt into the suction cup.
It is necessary to provide a female screw for screwing a bolt or a nut at the lower end of the leg, and there is a problem that the manufacturing and processing costs thereof are increased.

[0005] Further, the bathtub base of the second example includes a leg pipe 2
02 is provided with a leg pipe insertion groove 203a
Since the lower end of the leg pipe 202 is press-fitted and just attached, the press-fit may loosen during use and may come off, and when the bathtub is lifted up to remove the bathtub from the bathtub, the suction cup is attached to the bottom of the bathtub. Removed from the leg pipe while adsorbing,
There is a problem that only the suction cup may remain on the bottom of the bathtub.

[0006] Furthermore, when the suction cup 202 is installed at a rising R portion near the inner wall of the bathtub at the bottom of the bathtub in an attempt to install the bathtub table at a corner in the bathtub as much as possible.
The leg pipe 202 attempts to maintain vertical while the leg pipe 202 tries to maintain the vertical while the upper end of the leg pipe 202 is inclined in accordance with the portion, so that the deformation such that the groove width of the leg pipe insertion groove 203a is widened as shown in FIG. As a result, there is a problem that the press fitting is loosened and the suction cup may come off from the leg pipe.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a suction cup attached to a leg with a simple and low-cost structure, so that the suction cup does not come off during use or at the time of attachment and detachment. Another object of the present invention is to provide a bathtub having a suction cup that can be fixed to a rising R portion near the inner wall of the bathtub at the bottom of the bathtub without coming off from the bathtub leg.

[0008]

In order to achieve the above object, the invention according to claim 1 is provided with a suction cup at a lower end of a leg pipe supporting a seating surface, and the suction cup is provided on a bottom surface of a bathtub. In the bathtub table installed by suction, the suction cup is inserted from a lower end of the leg pipe and the fixing member inserted from a hole provided at a predetermined height from the lower end of the leg pipe. It has an insertion part fixed to a pipe, and a suction part of the above-mentioned suction cup and the above-mentioned insertion part are formed by the same material, and are characterized by the above-mentioned.

In the present invention, since the suction cup is securely fixed to the leg pipe with a simple and low-cost structure, the suction cup does not come off during use or detachment, and is safe. When a suction cup is installed in a part, even if the suction part of the suction cup is inclined, the insertion part formed integrally with the suction part expands and contracts by elastic deformation, and the insertion part remains fixed by the fixing member. Without falling off the leg pipe,
It is safe because it can be absorbed and fixed to the inside of the bathtub.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described. 1 to 4 are diagrams showing an embodiment of the present invention. The bathtub base 1 of this embodiment includes a seating surface 2 and a leg pipe 3, and a suction cup 4 is attached to a lower end of the leg pipe 3.

The suction cup 4 comprises an insertion portion 4a, a base portion 4b, and a suction portion 4c, and is integrally formed of a soft material having a hardness capable of being elastically deformed and sucked. The base portion 4b has a substantially cylindrical shape and extends vertically from the upper center of the suction portion 4c, and its outer diameter is slightly larger than the outer diameter of the leg pipe 3. The insertion portion 4a also has a substantially cylindrical shape and extends vertically from the upper center of the base portion 4b, and its outer diameter is substantially the same as the inner diameter of the leg pipe 3. Further, as shown in FIG. 2, two groove portions 5 are provided continuously to the insertion portion 4a and the base portion 4b.

Then, as shown in FIG. 3, the insertion portion 4a is inserted into the lower end of the leg pipe 3 until the base portion 4b reaches the lower end of the leg pipe 3, and is inserted at a predetermined height from the lower end of the leg pipe 3. The sucker 4 is fixed to the leg pipe 3 by tightening the tap screw 7 from the countersunk hole 6 provided in the hole. At this time, the suction cups 4 are inserted so that the projections 6a of the countersunk holes 6 protruding into the inside of the leg pipes 3 fit into any one of the two grooves 5 without contact, and the remaining suction cups are inserted. One groove 5 functions as a drain groove for draining water accumulated in the leg pipe 3.

The bathtub table 1 of the present embodiment is constructed as described above, and the suction cup 4 is securely fixed to the leg pipe 3, so that it does not come off during use or detachment and is safe. Further, when the suction cup 4 is installed at the rising R portion near the inner wall of the bathtub at the bottom of the bathtub, the insertion portion 4a is fixed by the tap screw 7 even if the suction portion 4c is inclined as shown in FIG. Since the lower part of the insertion portion 4a below the tightening position of the tap screw 7 expands and contracts by elastic deformation and follows the inclination, the suction cup 4 does not come off from the leg pipe 3 and can be suction-fixed and fixed to the inner surface of the bathtub for safety.

The bathtub according to the present invention is not limited to the above embodiment. For example, the bathtub table 1 of the above embodiment
In the above, a tap screw was used as a fastening member of the suction cup. However, a through hole may be provided in an insertion portion of the leg pipe and the suction cup, and the suction pipe may be fixed through a rivet pin.
