Description

TECHNICAL FIELD The present invention relates to a mounting structure, a mounting kit, and a mounting method for a washbowl, and more particularly to a mounting structure, a mounting kit, and a mounting method for mounting a standing washbowl to a top plate of a washbasin counter.

2. Description of the Related Art Conventionally, washbowls used in washstands (also referred to as washstand counters) include an embedded type that is used by being embedded in the counter and a standing type that is used by being placed on the counter. Washbowls are made of various materials such as ceramic, metal, glass, and resin. The present applicant provides washbowls made of ceramic, metal, glass, acrylic, and PET (polyethylene terephthalate) as stationary washbowls (for example, see Non-Patent Document 1). .

As described in this non-patent document 1, when a standing washbowl is mounted on the top plate of the washstand counter, the through hole of the washbowl and the through hole of the top plate below it are installed from the inside of the washbowl. A cylindrical drain plug is inserted into the top plate, a cleaning pipe is attached to the drain plug projecting downward from the back surface of the top plate, and the cleaning pipe is fixed with a nut on the back side of the top plate.

In the case of such a mounting structure, it is necessary to perform the work of attaching and detaching the washbowl in a narrow space below the top plate of the washstand counter, and the work is difficult. In addition, it is possible to replace several types of stand-alone washbowls, but in the case of the above mounting structure, not only the washbowl but also the cleaning pipe must be removed, so this work is not necessary. Unfamiliar general users sometimes felt hesitation and resistance to replacement due to fear of water leakage.

The mounting structure uses screws to attach parts to the front side of the wall of the bathroom. A mounting structure is known in which a component can be mounted on a wall by tightening a screw from the front side of the component to a reinforcing member adhered to the back side (see, for example, Patent Document 1).

With the mounting structure described in Patent Literature 1, there is no need to tighten screws from the back side of the wall. However, this mounting structure cannot be applied as it is to fix a standing-type washbowl to a washbasin counter. This is because, in the case of a washbowl, it is necessary to run a pipe from the front side to the back side of the top plate of the washstand counter so that the water can drain from the washbowl to a drain pipe attached to the back side of the top plate. In the case of the mounting structure described in Patent Document 1, such drainage cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and enables a washbowl to be easily attached to or detached from a top plate of a washstand counter by working from the front side of the top plate. for the purpose.

In order to solve the above-described problems, the mounting structure for a washbowl according to the present invention provides a cylindrical tube inserted through a bowl through-hole formed in the washbowl and a top plate through-hole formed in the top plate of a washstand counter.

The drain pipe includes a back side drain pipe having a female threaded portion formed on the inner peripheral surface thereof to be screwed with the male threaded portion of the front side drain pipe. The front drain pipe passes through the bowl through-hole and the top plate through-hole from the inside of the washbowl, and the male threaded portion is screwed into the female threaded portion until the flange is locked inside the washbowl. It is structured to be fastened to the pipe, and the cylindrical part of the front drain pipe is configured in a cylindrical shape with an inner diameter slightly smaller than the diameter of the cylindrical part of the wrench, which has a cylindrical part made of an elastic member. .

According to the present invention configured as described above, the front drain pipe is rotated from the front side of the washbowl until the flange formed at one end of the cylindrical portion of the front drain pipe is locked inside the washbowl. Then, screw the male screw part of the front drain pipe into the female screw part formed on the inner peripheral surface of the cylindrical back drain pipe fixed to the back of the top plate to fasten the front drain pipe to the back drain pipe. By doing so, the wash bowl can be attached to the top plate of the wash counter. Conversely, by rotating the front drain pipe in reverse from the front side of the washbowl and loosening the fastening state between the male and female screw parts, The wash bowl can be removed from the top plate of the wash counter by releasing the screwed state between the male screw part of the front drain pipe and the female screw part of the back drain pipe. As described above, according to the present invention, the wash bowl can be easily attached to or removed from the top plate of the wash counter by working from the front side of the top plate of the wash counter.

An embodiment of a mounting structure and a mounting kit for mounting a stand-type washbowl to a top plate of a washstand counter will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a mounting structure and a stationary washbowl 100 to be mounted according to this embodiment. As shown in FIG. 1 , the washbowl 100 includes a body portion 101 and a cylindrical projecting portion 102 projecting downward from the lower end of the center position of the body portion 101 .

The shape of the body part 101 is arbitrary. In FIG. 1, the shape of the top peripheral edge seen from the top surface shows a circular, approximately hemispherical shape (for example, one of two shapes obtained by cutting a hollow sphere with a plane), but this is an example. Not too much. For example, the body portion 101 may have an elliptical shape, a rectangular shape, or another shape at the upper peripheral edge when viewed from above. Also, the body portion 101 may have an uneven shape.

The projecting portion 102 has a through hole (hereinafter referred to as a bowl through hole) 103 inside. The bowl through-hole 103 is a cylindrical hole through which the cylindrical portion 11 of the front drain pipe 10, which is one element of the mounting structure, is inserted. It should be noted that the projecting portion 102 is not an essential component of the washbowl 100, and a configuration in which the lower end of the center position of the body portion 101 is circularly opened may be employed. In this case, this opening corresponds to the bowl through hole.

The material of washbowl 100 is arbitrary. For example, the washbowl 100 can be made of PET (polyethylene terephthalate), but the material is not limited to this. For example, the washbowl 100 may be made of materials such as acrylic, polycarbonate, vinyl chloride, or other resins in addition to ceramics, metal, and glass.

The mounting structure according to the present embodiment for mounting the washbowl 100 configured as described above to the top plate 200 of the washstand counter comprises a front side drain pipe 10 made of metal and a back side drain pipe 20 made of metal. . In addition, as accessory parts used when attaching the washbowl 100 to the top plate 200, a bowl packing 30, a base 40, a base packing 50, a back side packing 60 and a fixture 70 are provided.

The front drain pipe 10 has a cylindrical portion 11 that is inserted through a bowl through hole 103 formed in the washbowl 100 and a through hole 201 formed in the top plate 200 (hereinafter referred to as a top plate through hole). are doing. The cylindrical portion 11 has a cylindrical through hole 12 inside, and a male screw portion 13 is formed on the outer peripheral surface of the cylindrical portion 11 . A ring-shaped flange 14 is formed at one end of the cylindrical portion 11 and projects outward from the circumferential edge thereof.

A ring-shaped bowl packing 30 is fitted to the outer peripheral surface of the tubular portion 11 . The bowl packing 30 is configured in a shape and size to fit in a recess 104 formed in the lower end of the central position of the washbowl 100 . The bowl packing 30 prevents water from leaking out of the cylindrical part 11 from the opening formed at the lower end of the washbowl 100, and the flange 14 directly hits the lower end of the washbowl 100 to damage the washbowl 100. It is intended to prevent damage, and is made of, for example, silicon. In FIG. 1, the shape of the bowl packing 30 is shown as a flat packing with a two-stage structure, but the shape is not limited to this. For example, a flat packing having a single-stage structure may be used.

When attaching the washbowl 100 to the top plate 200, the pedestal 40 is placed on the top plate through hole 201, and the washbowl 100 is placed on the pedestal 40.例文帳に追加The pedestal 40 has a cylindrical through hole 41 into which the protruding portion 102 of the washbowl 100 can be inserted. Further, the protruding portion 102 of the washbowl 100 is fitted inside the packing 50 for the pedestal. The pedestal 40, the pedestal packing 50, and the protruding portion 102 have substantially the same height. The pedestal packing 50 is made of silicon, for example, and has the role of enabling the washbowl 100 to be stably placed on the pedestal 40 .

The pedestal 40 and the pedestal packing 50 are not essential components for attachment. For example, if the top plate through-hole 201 is configured to have a size that allows the protrusion 102 of the washbowl 100 to be inserted, the protrusion 102 may be directly inserted into the top plate 200 . Alternatively, the protruding portion 102 may be inserted into the top plate 200 while the pedestal packing 50 is fitted to the protruding portion 102 .

The back side drain pipe 20 is a cylindrical drain pipe that is fixed to the back surface of the top plate 200 with a fixing bracket 70 . On the inner peripheral surface of the cylindrical portion 21 located on the upper side of the back side drain pipe 20, a female thread portion (see FIG. not shown) are formed. A male locking portion 22 having a hexagonal outer peripheral surface is formed near the upper end of the back drain pipe 20 . This male locking portion 22 has a role of positioning the fixture 70 .

The fixing metal fitting 70 has a female locking portion 71 formed in a size to just fit with the male locking portion 22 of the back drain pipe 20 . The female locking portion 71 is a prismatic through hole with a hexagonal cross section. A plurality of screw holes 72 are provided around the female locking portion 71 . A screw with a sharp tip is passed through the screw hole 72 and the screw is inserted into the back surface of the top plate 200 to fix the back drain pipe 20 to the back surface of the top plate 200 . At this time, the back side packing 60 is sandwiched between the back side drainage pipe 20 and the top plate 200.例文帳に追加

Here, an example in which the male locking portion 22 and the female locking portion 71 are configured with a hexagonal cross section has been described, but the shape is not limited to this shape. It is sufficient that the rear side drainage pipe 20 does not move in the rotational direction by fitting the male locking portion 22 into the female locking portion 71. For example, the shape may be a pentagon, a square, a triangle or other polygons, or an ellipse. and so on. Moreover, although the example which provided the screw hole 72 in the fixing metal fitting 70 here and fixed the fixing metal fitting 70 with a screw was demonstrated here, it is not limited to this. The back side drain pipe 20 should just be fixed to the back side of the top plate 200, and the fixing method is arbitrary.

FIG. 2 is a diagram showing a state in which the back side drainage pipe 20 of this embodiment is fixed to the back side of the top plate 200. As shown in FIG. As shown in FIG. 2, the back side drain pipe 20 is screwed to the back side of the top plate 200 using a fixing bracket 70. The back side drainage pipe 20 is not removed from the top plate 200. - 特許庁

FIG. 3 is a diagram showing a state in which the back side drainage pipe 20 is fixed to the back side of the top plate 200 as in FIG. As shown in FIG. 3, the front drain pipe 10 passes through the bowl through-hole 103 and the top plate through-hole 201 from the inside of the washbowl 100 until the flange 14 is locked inside the washbowl 100. As shown in FIG. The pipe 10 is fastened to the back side drain pipe 20 by screwing the male threaded portion 13 of the pipe 10 with the female threaded portion of the back side drain pipe 20 .

When the flange 14 is locked inside the washbowl 100, it means that the threading of the screw reaches the limit or near the limit, the flange 14 is locked at the bottom of the washbowl 100, and the flange 14 does not penetrate the bowl any more. It means a state in which it is impossible to advance in the direction of the hole 103 . In this embodiment, as shown in FIG. 3, the male threaded portion 13 of the front drain pipe 10 is screwed into the female threaded portion of the back drain pipe 20 until the flange 14 fits into the recess 104 at the bottom of the washbowl 100. and the locked state is reached. At this time, the bowl packing 30 is sandwiched between the flange 14 and the bottom of the washbowl 100 and accommodated inside the recess 104 in a compressed state.

The procedure for attaching the washbowl 100 to the top plate 200 as shown in FIG. 3 (the mounting method for attaching the washbowl 100 to the top plate 200) is as follows. As described above, when attaching the washbowl 100 to the top plate 200 , the back drain pipe 20 is fixed to the back surface of the top plate 200 in advance.

First, the pedestal 40 is placed on the top plate 200 , and the washbowl 100 is placed on the pedestal 40 with the pedestal packing 50 fitted to the projecting portion 102 of the washbowl 100 . In this state, the front drain pipe 10 is inserted through the bowl through-hole 103 and the top plate through-hole 201 . That is, the cylindrical portion 11 of the front drain pipe 10 is inserted from the front side of the bowl through-hole 103 to the back side of the top plate through-hole 201 . At this time, since the back side drain pipe 20 is fixed to the back surface of the top plate 200, the front side drain pipe 10 is rotated and the front side drain pipe is attached to the female screw portion formed on the inner peripheral surface of the back side drain pipe 20. The male threaded portion 13 of 10 is screwed.

Here, as shown in FIG. 4, when the front side drain pipe 10 is in a state where it somewhat protrudes from the front side of the bowl through hole 103, it is possible to hold the flange 14 of the front side drain pipe 10 by hand and rotate it. . However, as the screwing between the male screw portion 13 and the female screw portion progresses and the front drain pipe 10 enters deeply into the bowl through-hole 103, it becomes difficult to hold the front drain pipe 10 by hand, and the front drain pipe 10 is removed. It becomes difficult to turn by hand. In order to stably attach the washbowl 100 to the top plate 200, it is necessary to rotate the front drain pipe 10 to a state where it cannot be rotated any more, and then strongly fasten the front drain pipe 10 to the back drain pipe 20. Although desirable, this is difficult when working solely by hand.

Therefore, a dedicated wrench 80 as shown in FIG. 5B prepared for rotating the front drain pipe 10 is used. The attachment kit of this embodiment is configured by the front side drain pipe 10, the back side drain pipe 20, and the dedicated wrench 80. As shown in FIG. FIG. 5 is a diagram showing a configuration example of the wrench 80 according to this embodiment together with the front drain pipe 10. As shown in FIG. 5(a) shows a configuration example of the front drainage pipe 10, and FIG. 5(b) shows a configuration example of the wrench 80. As shown in FIG. As shown in FIG. 5B, the wrench 80 of this embodiment includes a gripping portion 81 and a cylindrical portion 82 erected from the gripping portion 81 .

In FIG. 5(b), the grasping portion 81 is configured by a substantially square prism, but the shape is not limited to this. For example, it may be a cylinder. The cylindrical portion 82 is a cylindrical body having a diameter R2 slightly larger than the inner diameter R1 of the cylindrical portion 11 of the front drain pipe 10, and is made of an elastic member. Rubber, for example, can be used as the elastic member, but the material is not limited to this. For example, elastomers or other resin materials may be used. Although the material of the grasping portion 81 is arbitrary, if it is formed integrally with the cylindrical portion 82 with an elastic member, the manufacturing cost can be reduced.

The difference between the inner diameter R1 of the cylindrical portion 11 and the diameter R2 of the cylindrical portion 82 is, for example, approximately 0.5 to 1 mm. This diameter difference enables the cylindrical portion 82 to be pushed into the cylindrical portion 11 and inserted, and after being pushed in, the wrench 80 is held by the elastic force and frictional force of the cylindrical portion 82. It is designed to allow it to be strongly fixed to the Since the larger the contact area between the inner wall of the cylindrical portion 11 and the columnar portion 82, the stronger the fixation, the columnar portion 82 preferably has a certain height or more. For example, the height of the cylindrical portion 82 is set to 1 cm or more.

FIG. 6 is a diagram showing a state in which the front drain pipe 10 is rotated using the wrench 80 of the present embodiment configured as shown in FIG. 5(b). As shown in FIG. 6, the front drainage pipe 10 is rotated by rotating the wrench 80 with the cylindrical portion 82 of the wrench 80 inserted into the cylindrical portion 11 . As a result, the male screw portion 13 of the front drain pipe 10 and the female screw portion of the back drain pipe 20 are screwed together until the flange 14 is locked inside the washbowl 100, and the front drain pipe 10 is connected to the back drain pipe. 20 can be strongly fastened.

After attaching the washbowl 100 to the top plate 200 by fastening the front drain pipe 10 to the back drain pipe 20 until the state shown in FIG. It is possible to attach a drain plug from the front side of the washbowl 100 to the inside of the washbowl 100 . As the drain plug, for example, as disclosed in Non-Patent Document 1, it is possible to use a type that allows the lid to be opened and closed by being pushed by hand.

As described in detail above, in this embodiment, the front drain pipe 10 and the back drain pipe 20 constitute the mounting structure of the washbowl 100 . The front drain pipe 10 has a cylindrical tubular portion 11 that is inserted through the bowl through-hole 103 and the top plate through-hole 201. A male screw portion 13 is formed on the outer peripheral surface of the tubular portion 11. A flange 14 is formed at one end of the shaped portion 11 . In addition, the back side drain pipe 20 is a cylindrical drain pipe fixed to the back side of the top plate 200 by the fixing bracket 70, and has a female threaded portion that is screwed with the male threaded portion 13 of the front side drain pipe 10 on the inner peripheral surface. forming. Then, the front side drainage pipe 10 is passed through from the inside of the washbowl 100 to the back side of the top plate 200, and the male screw part 13 is screwed with the female screw part until the flange 14 is locked inside the washbowl 100.例文帳に追加Thus, the front drain pipe 10 is fastened to the back drain pipe 20 with the top plate 200 sandwiched therebetween.

According to the mounting structure of this embodiment configured as described above, the front drain pipe 10 is rotated from the front side of the washbowl 100 until the flange 14 is locked inside the washbowl 100, and the top plate 200 is attached. By screwing the male screw portion 13 of the front drainage pipe 10 into the female screw portion formed on the inner peripheral surface of the back drainage pipe 20 fixed to the back surface and fastening the front drainage pipe 10 to the back drainage pipe 20 , the wash bowl 100 can be attached to the top plate 200 of the wash counter.

Conversely, by rotating the front drain pipe 10 in reverse from the front side of the washbowl 100 and loosening the fastening state between the male screw portion 13 and the female screw portion, the rear drain pipe 20 is fixed to the back surface of the top plate 200. The washbowl 100 can be removed from the top plate 200 by releasing the threaded state between the male threaded portion 13 of the front side drain pipe 10 and the female threaded portion of the back side drain pipe 20 while being fixed by 70.例文帳に追加As described above, according to the mounting structure of the present embodiment, the washing bowl 100 can be easily attached to or removed from the top plate 200 of the washing counter by working from the front side of the top plate 200 .

Moreover, in this embodiment, a dedicated wrench 80 for rotating the front drain pipe 10 is provided. By using this wrench 80, the male threaded portion 13 and the female threaded portion are deeply screwed together until the flange 14 is locked inside the washbowl 100, and the front side drain pipe 10 is firmly attached to the back side drain pipe 20. It is possible to conclude. In addition, since the front drain pipe 10 can be rotated simply by fitting the cylindrical portion 82 made of an elastic member into the tubular portion 11, the operation is easy. Moreover, since the columnar portion 82 is an elastic member, it does not damage the inner surface of the cylindrical portion 11 . In addition, since it is not necessary to provide the front drainage pipe 10 with a special mechanism for rotating the front drainage pipe 10, the front drainage pipe 10 is simple and functional in that problems such as water leakage and puddles during drainage are unlikely to occur. configuration.

In addition, although the said embodiment demonstrated the example which uses a straight pipe as the back side drainage pipe 20, it is not limited to this. For example, it may be a drainage pipe with a curve or bend.

In addition, the above-described embodiments are merely examples of specific implementations of the present invention, and the technical scope of the present invention should not be construed in a limited manner. Thus, the invention may be embodied in various forms without departing from its spirit or essential characteristics.
