JPS6014870Y2 - Watertight mounting structure for water tank and top plate - Google Patents

Description

[Detailed description of the invention] This invention relates to a watertight mounting structure between a water tank such as a sink or washstand and a top plate.

Conventionally, a wooden top plate with a synthetic resin decorative thin plate attached to the surface,
For a watertight installation structure with a metal aquarium such as stainless steel,
The upper end flange 8 of the metal water tank 5 is overlapped on the lower surface of the extended edge 11 of the decorative board 2 on the upper surface of the top plate 3 shown in FIG. From aquarium 5
There was one in which the top plate and the water tank were connected in a watertight manner by installing a smooth sloped surface vertically.

Alternatively, the mounting structure shown in FIG.
Adhered with adhesive or filler 13, and on the back side of the rim,
The aquarium 5 and the top plates 2 and 3 are fixed together by pouring a reinforced polyester resin 14 through an intermediate material 12 with good adhesion such as wood or resin, and hardening and adhering it.

In addition, recently, a hole 2 with a larger diameter than the opening of the aquarium 3 is provided in the top plate 1 with the decorative board 1a attached to the wooden part 1b, and the aquarium is fitted therein to absorb the dimensional error of the opening and to The third
There was a structure in which a thermosetting resin 5 was poured between a water tank with bent flanges 4a and 4b shown in the figure and a recess 1' on the lower surface of the top plate.

However, the structure shown in Figure 1 has poor adhesive performance.
There is a problem with deterioration due to changes over time, and although the one in Figure 2 is better than the one in Figure 1 because it uses a combination of adhesive, reinforcing resin, and intermediate material, it still has the problem of deterioration due to changes in adhesive and resin. There is a problem similar to that shown in Fig. 1, and during long-term use, transportation, and installation, there is a risk that the resin will be damaged due to vibrations and knocks, making it impossible to ensure watertightness.

In addition, the water tank cannot be fitted from above the opening of the top plate, which is so-called lower attachment, and must be attached from the bottom side of the top plate, which is time-consuming.

The structure shown in Figure 3 is easy to install, but since it is a bonded structure made only of thermosetting resin, there is a risk of cracking or chipping due to knocking or vibration during installation of a drain trap, etc., or during transportation. Since there is no other means of connecting the top plate and the aquarium, there is a risk that the aquarium may tilt, leak, or even fall in the unlikely event of an accident.

The present invention has an improved structure that eliminates the above-mentioned conventional drawbacks, and the water tank is fitted from above the top plate so that it cannot be pulled out.
It is a combination.

Examples will be described below with reference to the drawings.

FIG. 4 is a longitudinal sectional side view showing one embodiment of the present invention.

FIG. 5 is an enlarged view of the main part.

1 is a top plate, with a synthetic resin decorative board 11 on the surface of a wooden base plate 12.
The lower part of the large-diameter opening 3 is provided with an inward stepped part 4 in a cross-sectional shape (step-like shape), and a small-diameter lower opening 3' (toward the lower end) is formed. There is.

Reference numeral 2 denotes a metal water tank made of stainless steel or the like, which has a curved flange 2' extending outward at its upper end, which is fitted into the opening 3 of the top plate, and the flange 2' is fitted into the inner step 4 of the top plate. The dimensions are such that it can be supported on.

The back surface of the flange edge is ground to form a rough surface.

Reference numeral 5 denotes a connecting auxiliary piece which also serves as a spacer, and is mainly made of bent metal and has a parallel cross section.

The connecting auxiliary pieces 5 are cut to an appropriate width and are supported and placed on the inner edge line of the top plate stepped portion 4 at appropriate intervals, typically 100 rrL/rrL to 200 rrL/wind.

Further, the arrangement direction is such that the upper long side faces inward and the flange 2' of the water tank 2 is placed on it, and the lower short side is supported on the step portion 4 described above.

Further, the height of the upper surface of the flange 2', which is fitted into the top plate opening 3 and supported by the connecting auxiliary piece, is lower than the top end of the top plate, as described in 1.2. 3 and other parts commonly used in conventionally known aquarium equipment of this type.

6 is a resin for filling and bonding, that is, urethane resin or other thermosetting resin, and various jigs, surface plates, etc. It is filled and solidified using a known method of injecting the material into the container.

During the filling and solidification, in order to obtain sufficient watertightness,
As shown in FIG.
The liquid is poured from the upper surface to the outer end surface of the container, and is then bent and filled into the top plate step portion 4 and the lower opening 3'.

The solidified resin 6 is tightly bonded to the back surface of the flange 2', which has a rough surface, to prevent slippage, and the connecting auxiliary pieces 5 are also integrally included and solidified here and there.

Furthermore, since the water tank also has a bent recessed step at its upper end, the resin 6 is also fixed to the outer surface of the bent recessed step.

Note that since the properties of the adhesive member tend to become hard and brittle due to cold temperatures, it is desirable for a structure suitable for cold regions to buffer sudden changes in the temperature difference between cold and heat.

The desired structure is achieved not only by simply bonding materials with widely different coefficients of expansion, such as urethane resin and metal water tank, but also by applying primer treatment for buffering.

That is, by applying a primer treatment with epoxy resin or the like between the metal surface and the urethane resin on the upper and lower surfaces of the metal flange edge and the outer surface of the connecting auxiliary piece, hot water for washing and cleaning operations can flow in cold regions. The epoxy resin acts as a buffer between the metal urethane resin and does not adversely affect the watertight mounting structure between the top plate and the aquarium even if it is poured or shrinks due to cold air.

The auxiliary connection piece shown in FIG. 6 has an integral structure in which the rim of the metal water tank is extended and bent, and notches are provided at predetermined intervals.

The one in which convex portions are provided at appropriate positions on the stepped portion of the top plate is also made of wood and serves as a connecting auxiliary piece to further improve adhesiveness.

In the figure, 7 indicates a front curtain plate, 8 indicates a cabinet, and 13 indicates a rising portion.

As described above, both the opening of the top plate and the opening at the upper end of the water tank constitute a bent step - the water tank opening 8 is connected via the waist connecting auxiliary piece 5
is supported on the step part 4 of the top plate, and the resin 6 is sufficiently filled in this bent mounting gap and solidified, so that the top plate 1 and the water tank 2 are
is an integrally connected structure.

The aquarium 2 has a bent upper opening and a lower body.
There is no difference whether they are molded separately or integrally.

Of course, the connection auxiliary piece 5 may also be formed by extending and bending from the aquarium rim, instead of being a separate piece.

The watertight structure of the present invention with the above configuration has the following effects.

■ Because the aquarium rim is supported on the step of the top plate,
There is no risk of the aquarium falling under any circumstances.

The rough back surface effectively acts on the adhesive solidification of the resin and strengthens it.

■ The aquarium can be easily fitted into the top plate from above.

■ The connecting auxiliary piece also serves as a reinforcing frame.

■ The bending shape of the resin 6 and the configurations described in ■ and ■ above prevent the aquarium from tilting involuntarily, and the resin remains straight throughout, even against the strong tensile forces that act when connecting the drain trap and the drain pipe to the aquarium. There is no risk of cracking or chipping, and the resin adhesive is used to sandwich the upper and lower surfaces of the rim, ensuring watertightness.

■ The bonding structure is strong against vibrations during transportation and use.
