Description

TECHNICAL FIELD The present invention relates to a wooden bathtub.

[Conventional technology]

BACKGROUND ART A conventional wooden bathtub is, for example, processed into a plate shape by naturally drying or naturally dried cypress, and is assembled as a side plate and a bottom plate.

[Problems to be solved by the invention]

In the bathtub, when water supply for bathing and drainage for cleaning and the like are repeated, the plate material forming the bathtub alternately repeats a wet state and a dry state. As a result, the plate material will be cracked and water will be leaked. The above-mentioned cracks occur earlier in particular when the hot water (or water) in the bathtub is left undrawn for several days due to water saving or the like. In such a case, repairing such as filling the cracked part with a filling material such as resin is extremely labor-intensive and costly, and even if such partial repair is performed, use of the bathtub As long as the above is continued, cracks will occur at other points, requiring frequent repairs. In addition, the bathtub repaired in this way has a problem that the aesthetic appearance is deteriorated.

[Means for solving problems]

The present invention has been made in view of the above problems, and the feature of the present invention bathtub is that the wooden board materials are pasted together via a water-resistant sheet, and each wooden mouth of a plurality of laminated boards Butt and solidify in a state in which the laminated resin is impregnated from the recesses by filling a synthetic resin liquid into the voids defined by the groove-shaped recesses formed along the longitudinal direction of each of the mouths. And formed by joining the laminated plates with each other by a joined body formed by, and consisting of a side plate and a bottom plate, and
The gap formed between the lower part of the side plate and the mouth of the bottom plate is filled with a synthetic resin liquid, and is hardened and impregnated in both the lower part of the side plate and the mouth of the bottom plate. The side plate and the bottom plate are combined. It is characterized by that.

[Action]

In the bathtub configured in this manner, even if the laminated plate material on one side is cracked, the water-resistant sheet interposed between the plate materials does not cause water leakage in the direction of the plate material on the other side, therefore, Semi-permanently with no water leakage and aesthetics can be maintained.

〔Example〕

An embodiment of the bathtub according to the present invention will be described below with reference to the drawings.

In FIG. 2, reference numeral 1 is a bathtub, which is composed of front and rear side plates 2, 3, left and right side plates 4, 5, a bottom plate 6 and an edge frame 7. More specifically, the side plate 2 (only the side plate 2 will be described because the other side plates 3, 4, and 5 and the bottom plate 6 have the same configuration) is shown in FIGS. 1, 3, and 4. like,
The laminated plate 12 having two layers by bonding two plate materials 12A and 12B to both sides of the water resistant sheet 9 with the adhesives 10 and 10 in the width direction (vertical direction for the side plates 2 to 5, that is, the height of the bath). Direction,
A plurality of bottom plates 6 are joined together in the horizontal direction. Here, as the plate materials 12A and 12B, as used in a conventional bathtub, a plate material that has been subjected to a treatment such as drying by a conventional method may be used, but in addition to that, Patent No. 1204986 (the title of the invention: "Method of processing wood into embedded wood"; Japanese Patent Application No. 55-39212, Japanese Patent Publication No. 58-18205)
You may use the board | plate material processed by the wood processing method concerning. Moreover, as the water resistant sheet 9, for example, 0.1 to 0.6
Use a vinyl chloride sheet with a thickness of mm, an aluminum sheet with a thickness of 0.1 to 0.15 mm, or a stainless steel sheet with a thickness of 0.1 to 0.8 mm. In addition, the joint portion between the laminated plates 12 is formed by notching groove-shaped concave portions 12D along the longitudinal direction (horizontal direction of the side plate 2) in each facing wooden mouth 12C of the laminated plates 12 to be joined. The synthetic resin liquid is filled in the void formed by the recess 12D by abutting the wooden mouths 12C, and the synthetic resin liquid is filled in the recess.
The laminated plates 12 are joined together by a joined body 13 which is solidified and molded in a state of being impregnated with 13A from the surface of 12D. Note that it is desirable to interpose an adhesive between the facing wood openings 12C, 12C.

Further, as shown in FIG. 5, notches 2A are provided at both ends of each inner side surface of the side plates 2 and 3 (only one end of the side plate 2 is shown).
Notches 4B are formed in the top and bottom of the side plates 4 and 5 (only one of the side plates 4 on the left side is shown) in the vertical direction so that the end of the side plate 2 and the side plate 4 can be opposed to each other. They are brought into close contact with each other, and in this state, the synthetic resin liquid is filled in the void formed by the notches 2A and 4B. Cut out this synthetic resin liquid 2A
The side plates 2 and 3 and the side plates 4 and 5 are connected by the combined body 15 which is hardened and molded in a state of being impregnated with 15A on both surfaces of 4 and 4B. Furthermore, as shown in FIG. 6, the side plates 2, 3,
Notches 2B (only the side plate 2 is shown) are also formed on the inner surfaces of the lower portions of 4,5, respectively, and the notches 2B and the bottom plate 6 facing the notches 2B are formed.
Similarly, the gap between the wood and the mouth 6A is filled with a synthetic resin liquid, and the side plates 2, 3, 4, 5 and the bottom plate are formed by the combined body 16 that is cured and molded while impregnating 16A in both the notch 2B and the wood mouth 6A. Combine 6 and. As each of the synthetic resin liquids described above, for example, a thermosetting resin liquid is used, and the synthetic resin liquid is injected or injected into the cavity formed by the joint portion and the joint portion and the mold mounted around them.

Then, the edge frame 7 is coupled so as to cover the upper and lower end portions 2G, 3G, 4G, 5G of the front and rear side plates 2 and 3 and the left and right side plates 4 and 5 which are coupled as described above. The edge frame 7 has a recess 7A formed on the lower surface as shown in FIG. 7, and is joined to the upper ends 2G to 5G by an adhesive 17 interposed between the recess 7A and the upper ends 2G to 5G. I am allowed. As shown in FIG. 6, the bottom plate 6 has a drainage hole 18 as shown in FIG. 2 and the water from the floor on which the bathtub 1 is installed is not guided to the bottom plate 6. The legs 19 made of synthetic resin are screwed to the four corners of the lower surface.

In the bathtub 1 having such a configuration, even if one or both of the plate materials 12A and 12B may be repeatedly wetted and dried and cracked due to the use thereof, hot water or water is removed from the bathtub 1 by the waterproof sheet 9. There is no leakage. In particular, in the case of using a plate material subjected to the treatment according to the above patent, in this plate material, moisture and sap of wood are completely removed by evaporation, and its composition changes to a state in which only fibers remain, and therefore, It exhibits water absorption similar to that of conventional dry wood, but has the characteristic that the drainage of absorbed water is much higher than that of conventional dry wood. As a result, the bathtub 1 composed of the side plates 2 to 5 and the bottom plate 6 made of such wood.
When the hot water is discharged after bathing, since it dries in a short time, cracks are less likely to occur, and therefore, the life of the bath is further extended in combination with the above-described water leakage prevention effect of the water resistant sheet 9. In addition, in this bathtub 2, the side plate 2
5 and the joints between the laminated plates 12 in the bottom plate 6, that is, the facing wood openings 12C, 12C are synthetic resin joints 1 with impregnation 13A.
3, and the joints between the side plates 2 and 3 and the side plates 4 and 5, and the joints between the side plates 2 to 5 and the bottom plate 6 are completely completed by the joint bodies 15 and 16 with impregnation 15A and 16A, respectively. Water leakage is prevented.

FIG. 8 shows a side plate (similarly for the bottom plate) for forming a bathtub according to another embodiment. The side plate 21 has a plate member 22A with three sets of the water resistant sheet 9 and the adhesive 10 as described above interposed. ~ 2
The case where the laminated plate 22 to which 2D is pasted is joined by the above joined body 13 is shown. Reference numeral 23 denotes an adhesive which is interposed between the wood openings 22A and 22A of the joint portion between the laminated plates 22.

According to the configuration in which a plurality of water resistant sheets 9 are interposed in this way, even if the outermost plate material 22A or 22D is broken, the innermost plate material is broken.
Since the crack does not spread up to 22B or 22C, the waterproof property is further enhanced.

In addition, in each of the above-described embodiments, the side plates 2 to 5, 21 and the bottom plate 6 are configured by joining a plurality of laminated plates 12 and 22 in the direction of the mouth, but such a joining structure should not be adopted. Needless to say, it may be configured by a single laminated plate with the waterproof sheet 9 interposed therebetween.

〔The invention's effect〕

The bath according to the present invention, from the above-mentioned configuration, even if the plate material is temporarily cracked by repeating wetting and drying with use, water leakage is prevented by the waterproof sheet, and repair is not necessary, and , Aesthetics are also maintained for a long time.
