Description

[Detailed Description of the Invention] <Industrial field of application> The present invention is a bathtub with a washroom made of glass fiber reinforced plastic used for a unit bath. The present invention relates to a structure in which ribs are individually provided so as to project, and the ribs are connected by a connecting body.

<Prior art> Conventionally, as a bathtub with a washing place of this type, for example, Jitsuko Sho 60-196
As disclosed in Japanese Patent Publication No. 79, the ribs of the bathtub portion and the washing area are respectively arranged in a straight line in the direction in which these two portions are connected, and the connecting body is formed in the shape of a strip plate longer than the distance between the both ribs. The end of each rib in the lengthwise direction is brought into contact with the end of each rib, and the screw is screwed in and fixed to prevent deformation or damage of the connecting portion between the bath and washbasin. is there.

<Problems to be solved by the invention> However, in such a conventional bathtub with a washing basin, the connecting body is easily deformed by the strip-shaped plate in the thickness direction and the twisting direction. , For example, when forces are applied to the bathtub and the washing area in a lateral direction orthogonal to the direction in which these two parts are connected, the connecting body is deformed and this force is concentrated on both screw fixing parts, and the screws are deformed. There is a problem that the ends of the ribs buckle and break.

Further, as in Japanese Utility Model Laid-Open No. 58-166795, an outer peripheral side rib and an inner peripheral side rib are projected from each bottom wall of the bathtub part and the washbasin part so that the bathtub part bottom wall outer periphery and the washbasin part bottom wall outer periphery are provided. A fitting groove is continuously formed between both ribs, and a frame-shaped leg is fitted into the fitting groove,
Although there is a prior art that gives strength to the bathtub part and the washbasin part against stress in alternate directions, since the foot stand that retains the strength is the same size as a bathtub with a washbasin, it can be carried into the construction site. Not only was it a big deal, but it was never cheap.

The present invention has been made in view of the above-mentioned conventional circumstances, and its technical problem is to prevent the concentration of force on each screw fixing portion by using a robust connecting body structure with a small size and a simple structure.

<Means for Solving the Problem> The technical means taken by the present invention to solve the above-mentioned problems are as follows. Claim 1 is a rib for the outermost part of the bathtub portion which faces in parallel with the back space of the bathtub apron. A long-side component piece end for connecting and fixing the connecting body to both of the ribs by fitting the connecting body into contact with each of the facing surfaces of the outermost ribs of the washing area and connecting and fixing the connecting body to the both ribs. The gist of the present invention is to have a structure in which the parts are formed in a rectangular frame shape in which short side constituent pieces are continuously provided.

A second aspect of the present invention is characterized in that a plurality of reinforcing ribs are installed in parallel over the facing long side component pieces at appropriate intervals.

<Operation> According to the above technical means, there is the following operation.

(Claim 1) Even if a force (twisting force) is applied to the bathtub section and the washroom section in alternate directions, the long-side component piece ends are formed into a rectangular frame shape in which the short-side component piece ends are connected in series. The ribs in the bathtub and the washing area cannot be moved alternately due to the corner reinforcement of the connected structure.

(Claim 2) The strength of the connected body is further strengthened by internal reinforcement in which a plurality of reinforcing ribs are provided in parallel in parallel with each other across the opposing long side component pieces.

<Effect of the Invention> The present invention, which is configured as described above, has the following advantages.

(Claim 1) A connecting body which is fitted and connected and fixed to the outermost ribs of the bathtub section and the outermost ribs of the washroom section that face each other in parallel across the back space of the bathtub apron is fixedly connected to the ribs. The long-side component pieces are formed into a rectangular frame shape with the ends connected to each other by the short-side component pieces, so that the bathtub part and the washroom part have a rectangular frame shape even when twisting forces act in alternating directions. Since both ribs cannot be moved alternately due to the corner strength of the body,
It is possible to effectively prevent stress concentration on each screw fastening part by using a connecting body that is small and easy and has a robust structure.
The screw will not be deformed and the end of each rib will not buckle and be damaged.

(Claim 2) Moreover, since a plurality of reinforcing ribs are installed in parallel in parallel with each other over the opposing long-side component pieces at appropriate intervals to internally reinforce the connecting body, the bath portion and the washing area are respectively provided. Even if a twisting force acts in a staggered direction, the above-mentioned corner reinforcement and inner reinforcement of the connecting body do not synergize and both ribs can be firmly connected so that they cannot be moved alternately. The buckling can be prevented more reliably.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, as shown in FIG. 1, ribs (3) and (3) are integrally projected in a lattice pattern on the bottom surface and back surface of the bathtub (1) and the washing area (2), respectively, and both ribs (3) ( 3) The inner ends (the outermost ribs of the bathtub and the outermost ribs of the washing area) (3a) (3a) that face each other across the back space (6) of the bathtub apron are attached to the bathtub (1) and the washing area. The parts (2) are arranged in parallel to each other at right angles to the connecting direction.

A connecting body (4) is fitted between the inner ends (3a), (3a) of both ribs that face each other across the back space (6) of the bathtub apron, and a connecting means is provided at a portion contacting with the connecting body (4). A plurality of insertion holes (3b) through which the screws (5) are inserted are formed facing each other at regular intervals.

The connecting body (4) is formed of glass fiber reinforced plastic, metal, or the like into a plane rectangular frame shape, and the vertical height dimension thereof is formed to be substantially equal to the protruding length of the rib inner end portions (3a) (3a). The outer width dimension of the pair of long side component pieces (4a) (4a) facing each other is formed to be substantially equal to the inner width dimension between the rib inner end portions (3a) (3a). (4a) (4a) is opened by a through hole (4b) at a position corresponding to the insertion hole (3b), and the long side component pieces (4a) and (4a) end portions are short side component pieces. Parts (4e) (4e) are installed in series, and long side component pieces (4a) (4a)
It has a structure in which it is reinforced by a plurality of reinforcing ribs (4c), which are installed in parallel at appropriate intervals, and the upper surface is closed by an integrated closing surface (4d).

Then, the screws (5) are inserted and screwed into the through holes (3b) and the through holes (4b), respectively, and the connecting body (4) is inserted between the rib inner end portions (3a) and (3a). Connect and fix.

On the other hand, what is shown in FIG. 4 is a modified example of the connecting body (4), which is one in which the blocking surface (4d) is not formed and is penetrated in the vertical direction.

The number and spacing of the reinforcing ribs (4c) formed inside the connecting body (4) are not limited to those shown in the figures, and are arbitrary.
Further, the closing surface (4d) may be formed on the lower surface of the connecting body (4) or the upper and lower intermediate portions.

Therefore, in the present invention, the long side component piece (4a) for fixing the connecting body (4) to the inner ends (3a) (3a) of the rib with the screw (5).
(4a) Long-side component pieces (4a) (4a) which are formed into a rectangular frame in which end portions are connected by short-side component pieces (4e) (4e) and which face each other.
Since a plurality of reinforcing ribs (4c) are installed in parallel at appropriate intervals over a) and have a structure that is strong against torsional forces, it is small and easy to provide only in the area directly below the bathtub apron space (6). By using a robust connecting body (4) with a different structure, it is possible to effectively prevent stress concentration on each screw (5) stop part and deform the screw (5) or the end of each rib (3a) (3a). Make sure the part does not buckle and break.
