Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit bath with a washroom which is obtained by appropriately connecting components such as a bathtub and a waterproof pan incorporated in a unit room.

[0002]

2. Description of the Related Art As has been known, as a unit bath constructed in a unit room, a waterproof pan for a washing place, a bathtub, etc., which have been integrally molded, have been adopted. Is good,
Particularly, in the case of remodeling, since considerable restrictions based on the carry-in space and the construction space are derived, the construction of the above-mentioned integrated unit bath is considerably difficult. Therefore, in order to solve the above-mentioned difficulties, what has already been presented are a two-division type unit bus A which is the first conventional example of FIG. 11 and a floor half-division type unit bus B which is the second conventional example of FIG. Has been done.

The above-mentioned waterproof pan two-divided unit bath A
As shown in the figure, the waterproof pan of the above-mentioned integrated unit bath is divided into two parts, and is divided into a bath pan waterproof pan a1 and a washroom waterproof pan a2. A total of two components, a bathtub a3 and an apron a4, is added to this. It is composed of four parts. And of course, the apron a4 above is the bath flange a5
And the waterproof pan flange portion a6 for the washing place and the waterproof pan flange portion a7 for the bathtub are sandwiched and connected to each other so as to be detachably erected.

With the above-mentioned construction, in the case of the first conventional example, the apron a4 is removed to expose the bath a3 side, so that various inspections and repairs on the bath a3 side can be easily performed at any time. Therefore, it can be implemented with good workability. Further, as an advantage of the conventional example, it is also possible to adopt different color selections for each of the four components, that is, the bathtub a3, the apron a4, the bathtub waterproof pan a1 and the washroom waterproof pan a2. As a result, it is possible to improve the color value of the product. However, on the other hand, the two-division type unit bus A has a large number of constituent parts as described above, and thus the mold cost and various material costs are inevitably increased, and as a result, the defect that the manufacturing cost becomes high is avoided. Can not do it.

Next, in the above-mentioned floor half-division type unit bath B, as illustrated in FIG. 12, the parts corresponding to the washing pan waterproof pan a2 in the above-mentioned two-division type unit bath A are eliminated and the wall is erected. The unit bath can be assembled with only two components, which are a bathtub with a flange b1 that can be installed and a waterproof pan b2 with an apron having an L-shaped side surface. And the above-mentioned waterproof pan b2 with apron for washing place is the waterproof pan part b3 for washing place,
It is integrally formed with an apron plate part b4 which is integrally erected from one side thereof, and working apices b5 and b5 are opened in the apron plate part b4, which are opened and closed by opening and closing small caps b6 and b6. It is designed to be detachable. Furthermore, the bathtub with flange b1 and the waterproof pan b2 with apron for the washroom are the upper end edge b of the flange b7 on one side and the apron plate part b4 in the bathtub with flange b1.
The floor half-divided unit bath B is configured by connecting 8 and 8 by appropriate means.

Due to the above-mentioned structure, the second conventional example requires only two parts as compared with the first conventional example, namely, a bathtub with a flange b1 and a waterproof pan b2 with apron for a washing place. Therefore, the workability is improved. However, since a special form is required for the two parts, it is impossible to use other types of components including the first conventional example as they are, and as a result, a new mold is inevitable for both parts. This will eventually force you to make a significant investment. Further, as described above, since the work mouth b5 is opened in the apron plate part b4 integrally formed with the aquarium waterproof pan b2 with the apron, and this is closed by the opening / closing small lid b6, the work can be performed even when the lid is opened. The workability in inspection and repair from the small edge b5 is poor, and because the configuration is made up of two parts, the color selection is limited to two colors, and the degree of satisfaction is low in terms of improving the color product value. .

[0007]

DISCLOSURE OF THE INVENTION The present invention has been studied in view of the deficiencies of the above-mentioned first and second prior arts. When the unit bath with a washing basin according to claim 1 is used, it is for a bathtub and a washing basin. A watertight pan and both parts are connected by a simple standing frame, and a large bath opening for opening is installed in the standing frame to be opened and closed. I am trying.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The unit bath with a wash basin according to claim 1 of the present application will be described below in detail with reference to FIG. 1. A bathtub 1 and a waterproof pan 2 for a wash basin, and a standing connection frame that is smaller and lighter than these. 3 and the bathtub shield plate portion 4. And the above-mentioned standing connection frame 3
As shown in FIG. 1 (B), the standing position is established by being connected between the higher bathtub flange portion one side 1a of the bathtub 1 and the lower washroom flange portion one side 2a of the washroom waterproof pan 2. Is held. Further, the bathtub shield plate portion 4 is detachably mounted on the washing pan waterproof pan 2 side of the work opening portion 3a which is largely opened in the standing connection frame 3. Here, as a portion equipped with the bathtub shielding plate portion 4, of course, as will be described later in detail, any one part or two parts of the bathtub 1, the washing pan 2 for the washing place, and the standing connection frame 3, and further three parts are provided. It can be selected as a target.

In the example shown in FIG. 1 (B), the bathtub shield plate portion 4 is fixed to the outer peripheral side surface 3b of the standing-up connecting frame 3 having a rectangular shape on the side of the waterproof pan 2 for washing place with screws or screws. It is fixed so as to be removable by appropriate means such as fitting and locking. Therefore, according to claim 1, the ready-made product can be used as it is as the waterproof pan 2 for the washing place which has been conventionally used, and the upright connecting frame 3 formed in a small and lightweight frame shape can be easily and quickly incorporated. Since it becomes possible to fix the work opening 3a, which is an opening in the standing connection frame 3, it can be freely closed by the bathtub shield plate portion 4, so that the bathtub 1 is normally shielded in a state where it cannot be viewed directly. A good appearance can be guaranteed.
Here, the material of the standing connection frame 3 may be synthetic resin, steel, etc., as long as it has a strength capable of sufficiently withstanding the load of the bathtub 1, the hot water and the bather, etc. A stainless steel plate is preferable, but a synthetic resin plate, a metal plate, or the like can also be used. Thus, according to claim 1, the working opening 4 of the upright connecting frame 3 can be largely opened by appropriately removing the bathtub shielding plate portion 4 as described above. Various work such as connection repair of pipes can be performed quickly and easily.

When the second aspect is explained, the bathtub 1 having the wall panel erection flange portion 1b attached thereto is used in the configuration of the first aspect. In the example illustrated in FIG. 1, the wall panel standing flange portion 1b is erected from the three side ends other than the bathtub flange portion one side 1a. Although such a bathtub with the wall panel standing flange portion 1b is known, the standing connection frame 3 formed in a rectangular shape as in the present invention.
In the unit bath with a washroom adopting as a component, the strength as a whole is enhanced by the standing of the wall panel standing flange portion 1b of the bathtub 1, and the durability is improved as compared with the case of claim 1. It can be improved.

Further, the contents of claims 3, 4 and 5, which are preferable to be adopted in carrying out the above-mentioned claims 1 and 2, will be described in detail below with reference to FIGS. 1 to 9. First, in claim 3, the bathtub shielding plate portion 4 is provided as shown in FIG.
(B) Then, as disclosed by the perspective view of FIG. 2, it can be detachably attached to the standing connection frame 3, whereby the working opening 3a is formed.
Is formed only by the opening lid 4A that can be opened and closed. Here, according to FIG. 1B, the standing connection frame 3
A concrete example of the standing configuration and the attachment configuration of the opening lid 4A will be explained. As a general construction procedure for the unit bath with a washing place, a waterproof pan 2 for the washing place and a bathtub 1 are installed. After that, the upright connecting frame 3 is airtight with respect to the boss 6 projecting on the backside of the bathtub flange portion one side 1a via the airtight material 5a with respect to the washroom flange portion one side 2a of the washroom waterproof pan 2. It will be sandwiched by interposing 5b. Further, in this embodiment, the upright connecting frame 3 is fastened and fixed to the washing place flange portion one side 2a by the screw 7a and to the boss 6 by the bolt 7b.

Then, the above-mentioned bathtub shielding plate portion 4 is pressed against the outer peripheral side surface 3b of the standing connection frame 3 via the airtight material 5c,
In the illustrated example, by fixing with a plurality of small screws 7c,
The working opening 3a of the standing connection frame 3 is closed. As understood from the above explanation, FIG. 3 is a perspective view showing the standing connection frame 3 and the opening cover 4A as the bathtub shielding plate portion 4, and in this figure, it is not shown. An airtight material 5c is provided along the inner peripheral edge 3c of the working opening 3a on the outer peripheral side surface 3b of the mounting and connecting frame 3, and the small screw 7c is inserted into the opening closing lid 4A. The wear holes 4a are opened by a required number of times.

Further, FIG. 4 shows a lid 4A for an opening portion, which is different from FIG. 3 in that an airtight material 5c is arranged. Therefore, as clearly shown in FIG. 2B, the fitting peripheral groove 4b is formed on the inner peripheral surface of the opening cover 4A.
The airtight material 5c is fitted around the above so as to be in a protruding state. In addition, in FIG.
A positioning side plate 8 is added to the content explained in (B). That is, the positioning side plate 8 is sandwiched between the standing plate portion 2b bent upward from the one side 2a of the washing place flange portion of the washing pan waterproof pan 2 and the standing connection frame 3 to thereby sandwich the positioning side plate 8. The upright connecting frame 3 can surely maintain the upright state and can obtain a strong connected state.

Next, FIG. 5 (B) is also provided with a positioning side plate 8 as described above, except that an anchor bolt 7d is provided for fixing the standing connection frame 3 to the washing place flange portion one side 2a. A guide holding bullet piece that is used and has its upper end fixed to the standing connection frame 3 and its lower end pressed against the standing plate portion 2b of the washing pan waterproof pan 2 so as to sandwich the positioning side plate 8 therebetween. Is added.

Further, in the example illustrated in FIG. 6, when the upright connecting frame 3 is fixed to the boss 6 on the one side 1a of the bathtub flange portion by using bolts 7b or the like, the fixing strength is further enhanced. It is an embodiment of the above. That is, the attachment plate portion 3e is bent outward from the inner plate portion 3d which opens the working opening portion 3a of the standing connection frame 3, and the guide plate is vertically guided from the outer end of the attachment plate portion 3e. The plate portion 3f is bent and bent. And the guide plate portion 3f
The airtight material 5d is interposed between the boss 6 and the hanging edge portion 1c of the bath flange 1 side 1a and between the boss 6 and the attachment plate portion 3e.
By fixing the attachment plate portion 3e to the boss 6 by b or the like, the guide plate portion 3f is sandwiched between the boss 6 and the hanging edge portion 1c via the airtight material 5d.

Next, the fourth aspect will be described in detail below with reference to FIG. 7, which also shows an embodiment of the first or second aspect. Here, unlike the case of the third aspect, the bathtub shield plate portion is shown. 4 is not only on the opening cover 4A described above, but also on the side of the waterproof pan 2 for the washing place of this and the opening cover 4A, and the main parts of the bathtub 1, the waterproof pan 2 for the washing place and the standing connection frame 3 It is configured by an apron 4B installed so that it can be attached to and detached from any one or more of the three parts. That is, as is known, the apron 4B itself may be sandwiched by the hanging edge portion 1c of the bathtub 1 or the like, may be locked to the washing pan waterproof pan 2, or may be supported by the both 1c and 2 and may be installed upright. It is also possible to selectively adopt the connecting frame 3 for use as an attachment point.

The apron 4B, which is one embodiment disclosed in FIG. 7, will now be described. An upper hooking portion 4d and a lower hooking portion 4e, which are bent inward in a hook shape, are formed above and below the apron body 4c. Is provided projectingly, and the locking vertical portion 4f of the upper locking portion 4d is inserted and locked between the standing connection frame 3 and the hanging edge portion 1c of the bathtub 1 via the airtight material 5e, The lateral portion 4g of the upper locking portion 4d is opposed to the lower end of the hanging edge portion 1c. On the other hand, a locking recess 3 formed by fixing a protruding locking projection 4h in the lower locking part 4e to the standing connection frame 3
g so as to be engageable with and disengageable from g, and the lower engaging portion 4e
A water draining port 4j is formed through the lower end sideways portion 4i.

Further, the following is a detailed description of claim 5.
Here, in the structures of claims 1 and 2, various embodiments of the standing connection frame 3 are disclosed. FIG. 8A shows a rectangular frame shape as already explained, which is assembled in a rectangular shape by the long side frame material 3h and the short side frame material 3i, but as shown in FIG. 8B. With respect to the standing connection frame 3 of (A) above, one or more aggregates 3j are detachably laid between a pair of long side frame members 3h and 3h as shown by phantom lines, and thereby, for working. You may make it divide the opening part 3a into a vertically divided state. By doing so, of course, the strength of the standing connection frame 3 can be increased, and by removing the aggregate 3j at a proper time, it hinders various works to be performed through the work opening 3a. In addition, as a mechanism for attaching and detaching the aggregate 3j, it is possible to adopt an appropriate means such as a fitting structure or a screw stop. It should be noted that here, 3k in FIG.
Shows a plate-like aggregate, which is equivalent to the above-mentioned aggregate 3j.

The standing connection frame 3 disclosed in FIGS. 8 (C) and 8 (D) is formed in a U shape in plan view (FIG. 8 (C)) formed by processing a metal plate-like material. 8 (D) is a perspective view thereof, showing a frame plate part 3m in which a work opening 3a is opened and a waterproof pan 2 for a washing place orthogonally from both side ends thereof.
It is formed by both side plate portions 3n and 3n bent toward the side, and thus the strength of the standing connection frame 3 is reinforced as in the case of FIG. 8B, and the weight is reduced. I am trying to get it.

The above-mentioned standing connection frame 3 and another embodiment of the opening cover 4A as the bathtub shield 4 will be described below with reference to FIG. This standing connection frame 3 is also the same as that shown in FIGS. 8 (C) and 8 (D) above in that it is U-shaped in a plan view, but the difference lies in the outer lower end of the standing connection frame 3. In this section, a U-shaped mounting edge surface 3p curved from the frame plate portion 3m to the side plate portion 3n is projected. On the other hand, in the opening closing lid 4A as the bathtub shielding plate portion 4, the side surface flat plate portions 4m, 4m are bent at right angles from both ends of the front flat plate portion 4k in the same manner as the standing connection frame 3 described above. Thus, the lower end edges of the front flat plate portion 4k and the side flat plate portions 4m, 4m can be placed on the U-shaped mounting edge surface 3p of the opening closing lid 4A. Thus, since the opening cover 4A is entirely fitted and locked in the standing connection frame 3, the small screws 7c and the like are inserted from the mounting hole 4a to remove both 3 and 4A. Work opening 3 as worn
a will be opened. With this structure, the overall strength is further strengthened as compared with the case illustrated in FIG. 8, and the work of integrating the two can be easily performed.

Next, the claim 6 will be described in detail with reference to FIG. 10 below. As in the case of claim 1 described above, the bathtub 1, the waterproof pan 2 for the washing space, and the high side bath flange portion one side 1a of the bathtub 1 are described. And a standing-up connecting frame 3 connected between the lower side of the wash-basin flange portion 2a of the wash-pan waterproof pan 2 and three main parts. Note that the above-mentioned waterproof pan 2 for the washing place is omitted in FIG. 10. According to claim 6, a bathtub having a small window 10a for work which is detachably attached to the outer peripheral side surface 3b of the standing connection frame 3 on the waterproof pan 2 for washing area. A shielding apron 10 is provided, and at this time, the work small window 10a can be opened and closed by a work small lid 10b detachably attached to the bathtub apron 10, and in the illustrated example, the work small window 10a Small working lid 10
Only b and b are provided.

Therefore, in the illustrated example, the bathtub shield apron 10 is used.
The upper edge plate 10c for mounting and the lower edge plate 10d for mounting are projected, and these are attached to the upper and lower outer peripheral side surfaces 3b of the standing connection frame 3 by screws (not shown) or the like. The small window 10a is opened in a window frame recess 10f provided on the protruding front plate 10e of the bathtub apron 10, and the working small window 10a has the working small lid 10b dropped into the window frame recess 10f. In this state, it is fixed so as to be detachable with screws or the like.

Therefore, according to claim 6, the number of parts is reduced and the bathtub apron 10 is one component as compared with the above case in which the bathtub shield plate portion 4 is constituted by the opening cover 4A and the apron 4B. By itself, the product value in appearance can be improved as compared with the case where only the opening lid 4A is used. Moreover, in the case of maintenance that can be performed by simple work, not only can the small work lid 10b be removed and the small work window 10b be opened to simply and swiftly respond, but also large-scale work is required. In this case, by removing the bathtub apron 10 from the standing connection frame 3 and opening the work opening 3a, it is possible to carry out a sufficient work without any hindrance, and the shape of the bathtub apron 10 may be uneven. Sufficient strength can be retained if appropriate deformation is added.

[0032]

Since the present invention is constructed as described above, according to the first aspect, the bathtub and the waterproof pan for the washroom, the lightweight and compact standing connection frame, and the working opening thereof. Since it is possible to obtain a unit with a washbasin only with a small bathtub shield plate that can open and close the part, compared to the conventional two-division type unit bath,
Since the main components can be halved and the waterproof pan for bathtub is not required, it can be provided at a low price. In addition, even if compared with the floor half-divided unit, the waterproof pan for the washing place, which is an existing part, can be used as it is, so that the die cost can be reduced and the product cost can be dramatically reduced. Furthermore, in the present invention, the conventional waterproof pan for a washroom with an apron is not used, but is separately manufactured into a standing connection frame and a waterproof pan for a washroom, and is vertically connected between the bathtub and the waterproof pan for a washroom. Since the frames are connected, the workability can be greatly improved. Moreover, since the working opening of the standing connection frame can be opened sufficiently large by removing the bathtub shielding plate at a proper time, the workability in the inspection, maintenance, etc. on the bathtub side is dramatically improved, and With regard to color selectivity, it is possible to effectively use the three colors to obtain satisfactory results in terms of color commercial value.

In the case of claim 2, the above-mentioned claim 1
In addition to the effect of the above, the wall panel erection flange portion is further provided in the bathtub, so that the connection strength with the bathtub can be secured even if the above-described standing connection frame is used. , More desirable results can be obtained. In the third to fifth embodiments, since the bathtub shielding plate is formed only by the opening lid, the number of parts can be minimized to achieve the above effect. It will be. Further, according to claim 4, since the shielding plate portion for the bathtub is configured so as to add not only the lid for the opening portion but also the apron, the commercial value can be further improved, and the standing value according to claim 5 can be obtained. It is designed to specify the form of the connecting frame, and by adding a square frame, aggregate, and U-shape in plan view, it is possible to increase the strength of the shielding plate for the bathtub, respectively. Claims 1 and 2
The effect of is made more certain.

Further, in the case of the unit bath with a washing room according to claim 6, a bathtub apron with a small window for work is adopted instead of the bathtub shield plate part in the above-mentioned claim 1, 2 Since it is configured so that it can be opened and closed with a small work lid, it is possible to reduce costs by reducing the number of parts, and when it is necessary to perform considerable work on the bathtub side, If you can open the work opening by removing the bathtub apron and can perform a relatively simple inspection or work, the work small lid can be easily and quickly removed to work from the small work window. It is possible to choose flexible measures.
