Embodiments of the present invention will be described below with reference to FIGS. FIG. 4 shows a bathtub 1 according to the present invention. The bathtub 1 includes a bathtub body 2 and a lid 3. As shown in FIG. 5, the bathtub main body 2 has a substantially rectangular parallelepiped shape, and a concave portion is formed on an upper surface thereof. A water tank part 2 for this recess to hold hot water
It is 1. One side 2a extending in the longitudinal direction of the bathtub body 2 on the upper surface of the side wall of the bathtub body 2 surrounding the water bath portion 21
And the other side part 2b is formed with locking recesses 22 and 23 extending along the longitudinal direction thereof, respectively. The locking recesses 22 and 23 are formed in the same shape and the same size as each other, but may be formed in different shapes and sizes.

On the other hand, the lid 3 is for opening and closing the upper end opening of the water tank 21 and is formed in a rectangular plate shape as shown in FIGS. Are arranged in the short width direction. The one end and the other end in the longitudinal direction are placed on one side 2a and the other side 2b of the bathtub main body 2, thereby closing the upper end opening of the water tank 21. The lid 3 has such a strength that it can sufficiently withstand a person riding on it while both ends in the longitudinal direction are supported.

In this embodiment, a plurality of the lids 3 are used. However, only one lid may be used to open and close the water tank 21 with one lid. However, the lid 3
In the case where only one is used, if the water tank portion 21 is large, the lid 3 also becomes large accordingly, making it heavy and difficult to handle. Therefore, it is desirable to use a plurality of lids 3 as in this embodiment. Of course, the number of the lids 3 is not limited to four as in this embodiment, but may be two.
, Three or five or more sheets may be used.

At one end and the other end of the cover 3 in the longitudinal direction, locking protrusions (locking protrusions) 31 and 32 extending in the width direction (longitudinal direction of the bathtub body 2) are formed, respectively. ing. The locking ridge 31 is arranged on one edge of the lid 2 in the longitudinal direction. The locking ridge 32 is disposed at a position slightly toward one end from the other end of the lid 2 in the longitudinal direction. The two locking projections 31 and 32 are formed in the same shape and the same size, but may be formed in different shapes and sizes. In this case, the locking ridges 31 and 32 are
It is formed so that it can fit into each of 2 and 23, respectively.

As shown in FIG. 3, when one end and the other end of the lid 3 are placed at appropriate positions on one side 2a and the other side 2b of the bathtub body 2, two locks are formed. Ridges 31, 32
Are inserted into and engaged with the locking concave portions 22 and 23, respectively. Here, the interval between the locking projections 31, 31 is substantially the same as the interval between the locking recesses 22, 23. Accordingly, the locking ridges 31 and 32 are formed by the locking recesses 22 and
When each of the lids 3 is fitted to the lid 23, the lid 3 is immovably locked to the bathtub main body 2 in its longitudinal direction (the short width direction of the bathtub main body 2). Moreover, the width of the locking recess 22 adjacent to the washing place is set to be approximately twice the width of the locking ridge 31. Therefore, when the locking ridge 31 is fitted into the locking recess 22, a space is formed outside the locking recess 22, and another locking ridge 31 can be fitted into the space. Then, the two lids 3 can be arranged side by side in the short direction on the washing place and the water tank 21. Here, the number of the locking recess 22 is one, but two locking recesses having the same width as the locking ridge 31 may be provided. However, from the viewpoint of easiness of manufacturing and easiness of cleaning, it is preferable that one locking recess is provided. On the lower surface of the lid 3, four fitting recesses 33 having a circular cross section are formed. Each fitting recess 33 is provided on the lower surface 4 of the lid 3.
It is arranged at each corner.

Next, a transfer table used for the bathtub 1 having the above-described structure will be described. As shown in FIGS. 1 to 3, in the transfer table 4 of this embodiment, two lids 3 are used. ing. One lid 3 is placed on the upper surface of one end in the longitudinal direction of the bathtub body 2, and locking projections 31, 32 are fitted into locking recesses 22, 23. Therefore, the lid 3 has the same situation as the case where it is used as a lid for shielding one end in the longitudinal direction of the upper end opening of the water tank 21. It is not always necessary to install this one lid 3, and only the other lid 3 may be used as the transfer table 4.

The other lid 3 is oriented such that its longitudinal direction is perpendicular to the longitudinal direction of the bathtub body 2.
And at the same height as one of the lids 3,
In addition, they are arranged at the same position in the longitudinal direction of the bathtub body 2. Moreover, the other lid 3 is, as shown in FIG.
One end is placed on one side 2 a of the bathtub body 2, and the locking ridge 31 is fitted into a portion outside the locking recess 22. Thereby, the other lid 3 has one end supported by the side 2a and is connected to the bathtub main body 2 so as to be immovable in the short direction. Moreover, the end face of the end of the other lid 3 where the locking ridge 31 is formed abuts against the end face of the end where the locking ridge 31 of the one lid 3 is formed.

The portion other than the one end supported by the side portion 2a of the other lid 3 is supported by the support portion 5. The support part 5 is installed on the floor F (see FIG. 3) of the washing place, and has four legs 51 that stand substantially vertically. Of the four legs 51, a lid receiving member 52 is located between the upper ends of a pair of legs 51, 51 located on the side away from the bathtub body 2 and separated in the lateral direction of the lid 3. Is provided. On the upper surface of the lid receiving member 52, a locking ridge 3
2 is formed with a locking concave portion 52a which is removably engaged. A connecting member 53 is provided between a pair of legs 51, 51 separated in the longitudinal direction of the lid 3. Connecting member 53
Are the other pair of legs 51,
51 are also provided. The connecting member 43 is disposed slightly below the lid receiving member 42.

The upper ends of the four legs 51 of the supporting portion 5 configured as described above are fitted into fitting recesses 33 formed on the lower surface of the other lid 3. Moreover, the other lid 3
The end of the tub body 2 away from the tub body 2 is placed on the lid receiving member 52. Thus, the other lid 3 is supported by the support 5. In this case, it is desirable that the lid 3 be supported so as to form a slight downward slope from the bathtub body 2 side toward the washing place side, rather than being supported horizontally. By doing so, it is possible to prevent hot water from accumulating on the lid 3. The locking projections 32 of the lid 3 are engaged with the locking recesses 52 a of the lid receiving member 52. Thereby, the other lid 3 and the support portion 5 are immovably connected in the short direction of the bathtub body 2.

In the above-described bathtub 1, since the cover 3 is used as a part of the transfer table 4, the number of parts of the transfer table 4 can be reduced by at least the cover 3. Therefore, the installation cost of the transfer table 4 can be reduced.

Next, another embodiment of the present invention will be described. In the following embodiment, only the components different from those in the above embodiment will be described, and the same components will be denoted by the same reference numerals and description thereof will be omitted.

FIG. 7 shows a second embodiment of the present invention. In this embodiment, a part of the side wall W of the bathhouse is used as a leg instead of the leg 51 of the support portion 5 of the transfer table 4. That is, the support recess Wa is provided on the side wall W.

Is formed in such a shape and size that an end portion on which the locking ridge 32 is formed can be inserted. And lid 3
Is placed on one side 2a of the bathtub body 2 with the locking ridge 31 formed thereon, and the other end is formed with a support recess Wa.
By being placed on the lower surface of the, it is supported substantially horizontally (actually, it is slightly inclined as described above). As will be apparent from the above description, a portion of the side wall W between the support recess Wa and the floor F of the washing place is also used as a leg for supporting the other end of the lid 3. Therefore, four legs are not necessarily required, and two of the legs 51 of the support portion 5 of the above embodiment on the side of the bathtub body 2 are omitted, and two legs separated from the bathtub body 2 are omitted. 51, 51 alone may be used.

In this embodiment, the side wall W of the bath is
It is only necessary to form the support recess Wa in the first embodiment, and no new member is required to constitute the transfer table 4A. Therefore, the installation cost of the transfer table 4A can be further reduced.

FIGS. 8 to 10 show a third embodiment of the present invention. In this embodiment, the transfer table 4
Three lids 3 are used. The three lids 3 are arranged in a state where the short direction is directed to the longitudinal direction of the bathtub main body 2 and the side surfaces extending along the longitudinal direction are in contact with each other. As a result, the length of the support portion 5 along the longitudinal direction of the bathtub body 2 is approximately three times the length of the support portion 5 in the above embodiment in the same direction, and the support portion 5 is enlarged. Therefore, in order to be able to easily store the support portion 5, two legs 51 provided with the lid receiving member 52 are provided.
The lower part 51A and the upper part 51B are provided between a place where the lid receiving member 52 is provided and a place where the connecting member 53 is provided.
And is divided into two. As shown in FIG.

The lower part 51A and the upper part 51B are rotatably connected to each other by rotatably fitting the protrusion 51a to b. Then, by rotating the lower portion 51A with respect to the upper portion 51B, the connecting member 53 can be positioned substantially on the same plane as the lid receiving member 52, whereby the volume of the support portion 5 can be reduced. Therefore, when the transfer table 4 is not used, it can be easily stored.

It should be noted that the present invention is not limited to the above embodiment, but can be changed as appropriate. For example, in the above-described embodiment, the locking projections 31 and 32 are formed linearly as the locking projections, and the locking recesses 22 and 23 are formed linearly correspondingly. The locking projections and locking recesses may be circular, square, or other shapes.
