Description

[Detailed Description of the Invention] The present invention relates to a vanity washstand having a ceramic part mounted on a housing part, and particularly relates to an improvement in the mutual connection and fixing structure.

This type of vanity washstand has a ceramic part equipped with a wash bowl and a back guard mounted on a housing made of decorative plywood or the like. This ceramic part must be connected and fixed by some means to prevent it from shifting. Conventionally, a mounting hole is provided on the bottom side during the manufacture of the pottery part, one end of the connecting fixture is engaged with this mounting hole, and the other end is fixed to the casing part.

By the way, in order to manufacture the above-mentioned pottery parts, raw materials such as clay are usually poured into a mold made of gypsum material and baked and hardened. At this time, water evaporates from the raw materials and the mold becomes hollow. Next, it needs to be dried, but since the bottom of the wash bowl protrudes from the bottom side, the pottery part must be placed in an upright position with the back guard facing down so as not to damage its shape. Since it would be impossible to stand on its own in this state, legs are provided protruding from the bottom rear side of the pottery section, and together with a back guard, the pottery section can stand in an upright position.

By the way, when drying the pottery part, by placing it in an upright position, the weight of the pottery part itself is applied to the back guard and the leg side. Therefore, the shape of the mounting hole is easily distorted and misalignment often occurs, so that the connecting fixture cannot be used in some cases. Particularly, since most of the weight of the ceramic part is applied to the attachment hole near the back side, which is the back guard side, deformation is large, and no effective preventive measures can be taken.

The present invention was developed with attention to the above circumstances, and its purpose is to prevent the deformation and positional shift of the mounting holes during the manufacturing process of the pottery part by providing mounting holes in the legs of the pottery part. It is an object of the present invention to provide a vanity washstand that can prevent such problems and improve the workability of connecting and fixing the connection with the casing.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a vanity washstand, which consists of a housing part 1 and a ceramic part 2. The casing 1 is provided with a front door and side panels (not shown) made of a decorative board made of, for example, melamine plywood, and the bottom plate 3 and the back plate 4 are made of veneer plywood. This housing portion 1 and the ceramic portion 2 are connected and fixed by means described later. The pottery section 2 is constructed as shown in FIG. That is, a back guard 5 protrudes upward from the back side, and a washing bowl 6 is integrally provided in the center. An overflow protrusion 7 is provided along the washbowl 6 and communicates with an overflow hole opened at the upper end of the washbowl 6 and a drainage hole (neither shown) opened at the lower surface. On the bottom surface of the pottery part 2, leg parts 8 are integrally protruded from both sides of the washing bowl 6. The leg portion 8 has a substantially triangular cross section that is higher on the back guard 5 side and gradually lowers toward the front side. A rectangular attachment hole 9a is provided in the bottom surface of the leg portion 8. A similar shaped mounting hole 9b is also provided on the bottom front side of the ceramic part 2.

In order to manufacture the pottery part 2, a raw material made of clay or the like is poured into a mold made of gypsum, baked, and after solidification, the mold is broken and dried. At this time, as shown in FIG.
The pottery part 2 is held in an upright position with the side facing down, and the washing bowl 6 is not brought into contact with the support surface R. Due to gravity, the closer it is to the support surface R, the more its own weight will naturally be applied. However, only the weight of the leg 8 is applied to the attachment hole 9a provided in the leg 8, and a force component is applied thereto since the leg 8 has a substantially triangular cross section. In other words, since it only adds a small amount of weight,
This deformation and positional shift can be ignored. The weight involved in the mounting hole 9b provided on the front side of the bottom is also very small. That is, in the standing state, since the distance between the upper end and the mounting hole 9 is short, only a part of the weight is added, and there is almost no deformation or positional shift.

The pottery part 2 constructed in this way is attached to the housing part 1.
In order to connect and fix it, do it as shown in Fig. 4. That is, the rectangular stop plate 11 fixed to the end of the screw 10 is inserted into the mounting hole 9a and rotated approximately 90 degrees. Therefore, the stop plate 11 engages with the mounting hole 9a, and the screw 10 is suspended from it. A reinforcing bar 12 is applied along the upper end of the back plate 4 constituting the casing part 1, and a hanging tool 13 is applied from the opposite side to fix it. This hanging tool 13 is bent into an inverted L shape, and a through hole 14 is bored in this horizontal piece.
The back plate 4 is fixed via the hanger 13 by inserting the through hole 14 into the screw 10 and screwing the wing nut 15 from the lower end. That is, the screw 10, wing nut 15, and hanging tool 13 constitute a connecting fixture 16. Similarly, the mounting hole 9b on the front side of the bottom surface and the side plate constituting the housing portion 1 may be connected and fixed via the connecting fixture 16. In any case, since there is no positional deviation between the mounting holes 9a and 9b, accurate mounting is possible.

As explained above, according to the present invention, the mounting holes are provided in the legs of the ceramic part, so that even if the ceramic part is made into a three-dimensional shape during the manufacturing process, the mounting holes will not deform or shift in position. Therefore, the connection and fixing for connecting and fixing the ceramic part to the case part can be performed accurately, and the workability can be improved.
