Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a counter with a low tank.

<Prior art> Conventionally, for a counter with a low tank, the wash counter and the low tank are molded separately, and these are carried to the site and installed and fixed.

The counter must be reinforced in order to maintain sufficient strength to withstand hanging the low tank, but in the prior art counters, support frames are fixed at appropriate intervals on the back side, and the low tank is attached to this support frame. There is a type with a fixed screw bush for installation.

However, the above-mentioned prior art counters have the following problems.

(1) Since the structure has support frames fixed to appropriate locations on the back of the counter, the entire counter is not reinforced, and the weight of the low tank acts on the counter itself, causing deformation such as bending and causing damage to walls such as bathrooms and washrooms. cannot be installed accurately.

(2) Due to bending or other deformation of the counter, there is a risk that the low tank fixed to the back side of the counter may fall off due to the peeling of the support rod and threaded bushing.

(3) Condensation forms on the back of the counter.

In addition, since the low tank can be hung on a counter, it needs to be lightweight, so in order to meet this demand, it is integrally molded from synthetic resin, and vertical protrusions are formed on the side wall at appropriate intervals to provide strength. It has been devised in such a way.

However, when attaching a low tank to a counter with screws, the vertical protrusions formed for reinforcement get in the way, resulting in poor workability.

<Technical Issues> The technical issue of this invention is to line the back of the counter body on which the low tank is hung with a material with excellent heat insulation and strength, and embed and fix the screw bushing for installing the low tank within the material. This gives the counter body insulation properties and sufficient strength to hang the low tank, and even if there are vertical reinforcing ridges formed on the side wall of the low tank, there is no need to use a special screwdriver with a long handle. The purpose is to enable the low tank to be attached to a counter body.

<Means for achieving the technical problem> The technical measures taken to achieve the above technical problem are: an apron surface on the front edge facing the interior of the room; In a counter with a low tank, the counter body consists of a counter body whose inspection port can be opened and closed with a lid that is flush with the top surface, and a low tank connected to the back side of the counter body. It consists of a main counter body with The screw bush for attaching the low tank is embedded and fixed, and the bottom wall of the low tank that connects the drain pipe is made one step lower than the other bottom wall parts and is integrally molded with synthetic resin. By recessing vertical grooves at regular intervals, reinforcing vertical protrusions are formed between the vertical grooves, and mounting flanges are formed at the opening edge portions on the vertical grooves. Of the protrusions, leave the upper area and reduce the protrusion amount of the outer surface of the entire length of the lower area to form a mounting space when attaching the low tank to the counter body, and use the mounting space to install. The flange portion is screwed to the screw bushing.

<Example> Next, an example of the present invention will be described based on the drawings.

In the figure, reference numeral 1 denotes a counter body, which includes a main counter body 1a having a substantially square planar shape with its front portion protruding in a substantially semicircular shape, and a sub-counter body 1b extending from one side edge into a rectangular planar shape. are integrally formed with FRP, other resin, or a metal plate, and the back surface is filled with a heat insulating material 22.

The main counter body 1a has a hanging opening 4 for the washbasin A at the center of its upper edge surface 1a', and the upper edge surface 1a' near the hanging opening 4 is equipped with a water supply tap, a hot water tap, or a hot water mixing tap 5. A communication hole 6 is opened, and in addition, a soap receptacle 7 is recessed.

The sub-counter body 1b has a stepped fitting step 9 for the inspection lid 8 formed on the upper edge surface 1b', and an inspection opening 1d is opened in the step 9.

In addition, the main counter body 1a, the sub counter body 1
b, an apron surface 10 is vertically formed on the front edge facing into the room C when the unit room C is inserted into the wall surface 1c in a protruding manner.

The heat insulating material 2 is formed by pouring resin concrete with high heat insulating effect flush onto the back surface of the counter 1 in a liquid state, and before the heat insulating material 2 solidifies, it is used for a hanging fitting 11 for suspending the washbasin A, and The screwing bush 3 for attaching the low tank D is positioned and embedded.

The low tank D is made of resin and is molded into a box-like shape with an opening 1D on the top surface using a molding method such as blowing or resin injecting, and the side wall 2D is left with a small area near the upper edge of the opening 1D at appropriate intervals. By recessing the vertical groove 3D up to the bottom wall 8D and forming the mounting flange portion 4D with the back surface of the sub-counter body 1b on the upper edge of the opening 1D, the side wall 2D portion is connected to the vertical groove 3D and the vertical groove 3D. The reinforcing shape is a continuous vertical striped pattern 6D with the reinforcing vertical protrusions 5D sandwiched between the grooves 3D.

In addition, in the low tank D, the bottom wall portion 8D to which the drain pipe 106 is attached is lowered one step lower than the other bottom wall portions 8D to form a recessed step portion _d1 , thereby eliminating dead water and allowing complete drainage. We take this into consideration.

The vertical grooves 3D are formed in the side wall 2D of the low tank D at appropriate intervals, so that the sub-counter body 1
Securing the mounting flange part 4D to b, and also attaching the low tank D with the vertical reinforcing ridge 5D that is inevitably formed.
It is designed to reinforce the The reinforcing longitudinal protrusion 5D is left in the upper region (for example, a position facing the apron surface 10 of the counter body 1), and the protruding outer surface 5D' of the entire length of the lower region is made shallow to create a mounting space 7D when installing the low tank. Configure.

This mounting space 7D is the mounting flange portion 4D.
The installation space 7D functions as a working space for screwing the screw into the screwing bush 3 embedded and fixed in the resin concrete, and due to the existence of this installation space 7D, a general screwdriver Z with a short handle can be used to screw the low tank D.
can be attached to the sub-counter body 1b.

In addition, the low tank D has a ball tap faucet 103 which opens the main valve by raising and lowering a float 100 floating on the water surface inside and supplies water from the tank water spouting part 101.
Then, by operating the operating lever 104 protruding from the side wall 2D, the float valve 105 is opened and the drain pipe 106 is opened.
Drainage device 1 that supplies flushing water to the toilet bowl X via
Equipped with 02.

The hanging fitting 11 is composed of a stud bolt 11a, a basin push-up piece 11b, and a lock nut 11c.

The washbasin push-up piece 11b is a vertical piece 11 of the main body A, which consists of a horizontal piece 11b' and a vertical piece 11b''.
A bent piece ``b'' is formed at the tip of the vertical piece 11b'' through a curved surface, and a through hole 13 for the stud bolt 11a is formed at the end of the horizontal piece 11b' on the vertical piece 11b'' side.

Therefore, the screw mounting button 3 of the main counter body 1a
Insert the washbasin push-up piece 11b into the stud bolt 11a, which has one end screwed, by fitting the through hole 13 into the stud bolt 11a, and insert the washbasin push-up piece 11b from the other end. The wash basin A is lifted up through the portion 11b' and is closely attached and fixed to the lower surface of the heat insulating material 2 on the back surface of the main counter body 1a.

On the other hand, the low tank D can be attached to the sub-counter by screwing and tightening the mounting screw 15, which is inserted into the insertion hole 14 formed in the mounting flange portion 4D, to the screwing bush 3 using a screwdriver Z through the mounting space 7D. The edge of the opening 1D is brought into contact with the bottom of the inspection opening 1d of the body 1b, and the body 1b is mounted and fixed in a suspended manner.

<Operations and Effects of the Invention> Since the invention is constructed as described above, it has the following effects.

Resin concrete was poured into the back of the counter body and allowed to harden, and the screw bushings for attaching the low tank were embedded and fixed in this resin concrete.This gives the counter body strength and heat insulation properties, and the screw bushings are attached to the counter body. Can be firmly fixed to the back of the body.

Therefore, we provide a counter with a low tank that does not cause bending deformation or rattling noise in the counter body, which prevents the risk of the low tank falling off, and which also has no condensation and is highly durable and easy to install on the mounting wall. be able to.

Of the reinforcing vertical protrusions formed on the side wall of the low tank, we created a space for mounting the low tank by reducing the amount of protrusion of the outer surface of the entire length of the lower part while leaving the upper part, so that the installation space when installing the low tank was created. When screwing the mounting flange part onto the screw using the screwdriver, your hand does not touch the reinforcing longitudinal protrusion. Therefore, the installation work can be carried out using a general screwdriver with a short handle, without using a special screwdriver with a long handle.

In addition, since the bottom wall of the low tank that connects the drain pipe is formed one step lower than the other bottom wall parts, there is no dead water and internal water can be completely drained.

Thus, the intended purpose can be achieved.
