DETAILED DESCRIPTION OF THE INVENTION The present invention provides a hemispherical locking portion 4 on the lower surface of the flange 2 of the bathtub 1, a hole serving as a locked portion 5 on the upper surface of the apron 3, and a locking portion 4 on the outer surface of the apron 3. A handle A is provided, and the lower part of the apron 3 is removably placed on the apron receiver 6 at the lower part of the bathtub 1, and the apron 3 is
A lower hole 18 provided at the lower part of the apron receiver 6 is removably engaged with a protrusion 15 provided on the apron receiver 6, and a lower hole 18 provided at the lower part of the apron receiver 6 is attached to a lower hole 16 provided on the bathtub 1 side than the protrusion 15 of the apron receiver 6. An apron attachment/detachment structure for a bathtub characterized in that the edges of the bathtub 1 side are opposed to each other, and a hole serving as a locked part 5 is removably inserted and locked into a hemispherical locking part 4. It is.

Conventionally, the apron 3' is fixed to the bathtub 1' with bolts 7' as shown in Figures 1a, b, and c, so it is difficult to remove the apron 3' after construction. Therefore, when cleaning the lower part of the bathtub 1', conventionally a water hose was inserted from under the apron 3' and the water jet was used to clean it, but with this method, cleaning is easier. Parts cannot be visually confirmed, cleaning is incomplete,
Moreover, it was difficult to remove bulky dirt and the like. Furthermore, it is also possible to remove and clean the entire bathtub 1', but with this method, the bathtub 1' can be removed from the pot and the connecting pipe.
The problem was that the bathtub 1' and the bathroom were likely to be damaged, which required removal, which was time-consuming and expensive because it could not be done by amateurs.

The present invention was invented in view of the above-mentioned conventional drawbacks, and its purpose is to make the apron removable so that it is easy to clean the floor surface where the bathtub is installed and the surrounding area. Another object of the present invention is to provide a structure for attaching and detaching the apron of a bathtub, which is easy to attach and detach by providing a handle.

The present invention will be explained in detail below with reference to Examples. In the figure, 1 is a stationary bathtub, and 3 is an apron that is detachably attached to the bathtub 1. A receiver 8 is attached to the side end of the lower surface of the flange 2 having a U-shaped cross section of the bathtub 1 with screws 9 and nuts 10, and the tip of the receiver 8 forms a U-shaped portion 11. Here, the hemispherical head of the screw 9 forms the locking portion 4.
On the other hand, a hole in which the hemispherical head of the screw 9 is removably locked is provided in the upper horizontal piece 3a projecting backward from the upper surface of the apron 3, and this hole is connected to the locked part 5.
It is becoming. Bolts 12 are attached to the legs 24 of the bathtub 1,
An apron receiver 6 is attached with a nut 13, and an apron mounting surface 1 is attached to this apron receiver 6.
4, a protrusion protruding upward on the apron placement surface 14, and a lower abutment 16 rising upward from the rear end of the apron placement surface 14, and the other at the back of the lower end of the apron 3. Lower horizontal piece 17 protruding towards
A lower hole 18 that is engaged with the protrusion 15 is bored in the lower hole 18 . Also, there are mounting holes 19 on the top left and right of the apron 3.
The handle A is attached using a screw or the like using this attachment hole 19. Of course, the handle A may be formed integrally with the apron 3. Further, holes 20 are bored in the left and right portions of the lower horizontal piece 17 of the apron 3 or in other parts, and a protective member 21 such as rubber or synthetic resin is attached to the hole 20.
This protective member 21 can be installed by removing the apron 3.
As shown in the figure, when leaning against the wall 22, the protective member 21 touches the floor 23, and the apron 3 directly touches the floor 23.
This is to prevent the floor 23 and the apron 3 from being damaged. Therefore, it is preferable that the protective member 21 has elasticity or flexibility. Therefore, when installing the apron 3, first hold the handle A of the apron 3 with both hands as shown in FIG. By applying it to the lower part 16 of the tool 6 and joining the protrusion 15 of the apron receiver 6 and the lower hole 18 of the lower horizontal piece 17, in this state, hold the handle A and push it in as shown in Fig. 5b. At the same time, the head of the screw 9, which is the locking part 4 of the flange 2, is fitted into the hole, which is the locked part 5, provided on the top surface of the apron 3, and at the same time, the U-shaped part 11 of the receiver 8 is inserted into the apron 3. The upper horizontal piece 3a is inserted and held, and the apron 3 is attached below the flange 2 of the bathtub 1. Here, as shown in FIG. 6c, the tip of the upper horizontal piece 3a comes into contact with or comes close to the vertical piece 11a of the U-shaped portion 11 of the receiver 8, so that the upper horizontal piece 3a does not go in too far. ing. By the way, if you want to clean the area below and around the bathtub 1, hold the handle A with both hands and remove the apron 3 in the reverse order of installing the apron 3 above, and clean the area below the bathtub 1, the floor, and the surrounding area while visually checking the area. It is something that does. As shown in the figure, if the hole serving as the locked portion 5 of the upper horizontal piece 3a of the apron 3 and the lower hole 18 of the lower horizontal piece 17 are made long holes, errors in attaching the apron 3 can be absorbed. . In the embodiment, the apron 3 is made of enameled steel plate, and the holder 8, apron holder 6, screws 9, etc. are made of diuracon. The apron receiver 6 is provided with a fitting protrusion 25, and the fitting protrusion 25 is fitted into the fitting hole 26 of the leg 24 of the bathtub 1. In this state, the bolt 12 and nut 1 are inserted.
If the apron receiver 6 is attached to the leg 24 in step 3, the apron receiver 6 can be attached to the leg 24 accurately and easily, and there is a risk that the apron receiver 6 may rotate even after attachment. There is no such thing. Further, 27 in the figure is a leg rubber provided at the lower end of the leg 24 of the bathtub 1.

Thus, in the present invention, as described above, a hemispherical locking portion is provided on the lower surface of the flange of the bathtub, a hole is provided on the top surface of the apron as a locked portion, and the lower portion of the apron is detachably attached to the apron receiver. At the same time, the lower hole provided at the bottom of the apron is removably inserted and locked into the protrusion provided on the apron receiver, and the hole that becomes the locked part is removably connected to the hemispherical locking part. Now that the apron has stopped, place the lower part of the apron on the apron receiver, insert and lock the lower hole in the lower part of the apron into the protrusion of the receiver, and then push the top of the apron into the hemispherical locking part. It can be locked in the hole on the top surface that becomes the locked part, and when removing the apron, pull the top of the apron toward you to release the hole from the hemispherical locking part, and then slightly remove the apron. The apron can be removed by simply lifting it up and removing the hole from the protrusion, and when installing and removing the apron, there is no need for tools such as screwdrivers or pliers without using bolts, nuts or screws. It is easy to work, and even housewives can easily install and remove it.Furthermore, the edge of the lower part of the apron on the bathtub side faces the lower part provided on the bathtub side from the protrusion of the apron holder. Therefore, by placing the lower part of the apron on the apron holder first, locking the lower hole in the lower part of the apron to the protrusion, and rotating the apron to attach the apron, it is easy to install even relatively heavy aprons. Although it is easy to install, the lower hole at the bottom of the apron, which is difficult to see and position, can be easily engaged with the protrusion by using the lower part as a guide, making it extremely easy to install the apron. In this way, the apron can be easily attached and detached from the bathtub, so when cleaning the floor below the bathtub and its surroundings, you can leave the apron on and insert the water hose from below the apron, as in the conventional method. You can easily and reliably clean the floor below the bathtub and its surroundings without having to clean the bathtub or remove the entire bathtub for cleaning.Also, you can easily remove bulky garbage, dirt, etc. It is possible to prevent rotting and generate no bad odor. Moreover, the top surface of the apron is close to the bottom surface of the flange, so even though the apron is removable, there is no part to touch when removing it, and a jig such as a screwdriver is used to connect the bottom surface of the flange to the top surface of the apron. The apron must be removed by inserting the apron in between, or by holding both sides of the apron with your hands, but this makes removal work difficult, and if you use a jig such as a screwdriver, the flange and apron may be removed. However, in the present invention, since a handle is provided on the outer surface of the apron, the apron can be attached and detached easily and quickly by holding the handle in the hand and performing the operation of attaching and detaching the apron. Become.

In the embodiment, an example was shown in which the handle protruded from the outer surface of the apron, but it goes without saying that the outer surface of the apron may be recessed and the recessed portion may be used as the handle.
