2. Description of the Related Art On the back side of cabinets such as sinks and sinks, there is a connection work for water supply pipes, hot water supply pipes, and drainage pipes with equipment installed on the building side where the sinks and washbasins are installed. There is an inspection port for performing or checking or repairing it.

Conventionally, this inspection port 10a is formed on a back plate 10 of a cabinet 9 as shown in FIG. 6, and is closed by a lid 11 having four screws fixed to the back plate 10 on four sides. At the time of installation work or inspection, the screw 12 is loosened to remove the lid 11 from the rear plate 10 so that the connecting portion of the pipe located at the rear of the cabinet 9 is operably exposed from the inspection port 10a. After completion of the work, the lid 11 is put on the front surface of the inspection port 10a so that its screw holes are aligned with the screw holes of the rear plate 10 and the screw 1 is attached.
It was supposed to be fixed at 2.

In the case of fixing the lid 11 with the screw 12 as described above, the rear plate 10 with which the tip of the screw 12 is screwed is relatively thin, and its holding is insufficient. Therefore, conventionally, as shown in FIG. 7, a reinforcing member 13 for screwing the screw 12 is attached to the back side of the back plate 10.

[0005]

In the above-mentioned conventional method of fixing the lid by the screws, it is necessary to attach a reinforcing member for screwing the screws to the back side of the back plate, so that a cabinet such as a sink or a washbasin is manufactured. However, there is a problem in that it takes time and effort to attach this reinforcing member, and this causes a cost increase.

In addition, the lid must be attached and detached at a narrow and dim place in the inner part of the cabinet by using a tool such as a screwdriver for attaching and detaching the screw, and when attaching the lid, There is also a problem that it is necessary to align the screw holes provided on the back plate, which makes the work difficult and requires a lot of working time.

Further, in the lid fixed with the screw as described above, if the screw is frequently attached and detached, the screw and the screw hole are loosely screwed, and the lid may be accidentally dropped. Had.

An object of the present invention is to solve the problems that the conventional attachment of the inspection port lid has.

[0009]

In the method of attaching the inspection port lid according to the present invention, in order to solve the above-mentioned problems, a lid for closing the inspection port formed on the plate is provided on the front surface side and the back surface side of the substrate. It is a method of mounting by using a fixture with a substantially S-shaped cross section in which a sandwiching piece and a hanging piece each having elasticity are projected, and the peripheral edge of the inspection port is inserted between the board and the sandwiching piece and clamped. The tool was attached to the plate body, and the edge of the lid was inserted between the substrate and the hanging piece so as to pinch and close the inspection port.

The fixture used in this attachment method is
The board has a substantially S-shaped cross section in which an elastic clamping piece and a supporting piece are provided on the front and back sides of the board. The supporting piece is slightly shorter than the clamping piece, and the peripheral edge of the inspection port is Is adapted to be inserted and clamped between the clamping piece and the substrate, and the end edge of the lid can be inserted and supported between the retaining piece and the substrate.

[0011]

The clamping piece formed on the back surface side of the fixture clamps the edge of the plate body having the inspection port formed between it and the central substrate to detachably attach the fixture to the plate body. Also, the hanging piece formed on the front side of the fixture hooks the edge of the lid with the board when the fixture is moved toward the lid, so that the lid closes the inspection port. Fix it to the plate. This lid can be easily attached and detached without using a fixing tool such as a screw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a lid 7 of an inspection port 6a according to the method of the present invention.
It is a front side perspective view of the washbasin cabinet 1 showing an example of attachment. As shown in the figure, a washbasin cabinet 1 to which a lid 7 according to the method of the present invention is attached has a substantially box shape, and a wash bowl 3 and a mixed water faucet 2 are provided on the upper surface thereof. An opening / closing door 4 is pivotally attached to the front surface at one end thereof, and a space below the washbasin 3 serves as a storage portion 5.

The washbasin cabinet 1 is used by being installed at a predetermined position in a building. At that time, a pipe (not shown) connected to the mixing faucet 2 and a washbasin 3 are used.
It becomes necessary to connect the drainage pipe 3a and the like communicating with the water supply pipe, the hot water supply pipe, or the drainage pipe (not shown) provided on the building side. This connection is normally made after the washbasin cabinet 1 is placed at a predetermined position, so that the rear plate 6 of the washbasin cabinet 1 is subjected to this work or an inspection after installation. An inspection port 6a is provided for this purpose. A lid 7 is attached to the front surface of the back plate 6 so that the washbasin cabinet 1 can be attached to and detached from the storage section 5 side, and the inspection port 6a is closed.

Here, in the method of the present invention, the lid 7 is attached to the periphery of the front side of the inspection port 6a formed in the back plate 6a via the attachments 8 provided on the four sides.

FIG. 5 is a perspective view showing an embodiment of the fixture 8 used in the method of the present invention. This fixture 8 is, for example, formed by folding back both ends of a metal plate to the front surface side and the back surface side to form a substantially S-shaped cross section. An elastic sandwiching piece 8a is formed, and a hanging piece 8c shorter than the sandwiching piece 8a is formed on the front surface side of the substrate 8b.

The fixture 8 may be integrally formed of a flexible synthetic resin material.

Next, a method of attaching the lid 7 using the attachment 8 will be described. First, as shown in FIG.
An inspection port 6 is provided between the substrate 8b in the center and the sandwiching piece 8a on the back side.
The back plate 6 having the a formed therein is inserted so as to sandwich the edge thereof. In this way, the fixtures 8 are attached above and below the inspection port 6a. At this time, the surface side of the fixture 8 (the side on which the hanging piece 8c is provided) is positioned on the front surface of the back plate 6. Then, the hanging piece 8c formed to be shorter than the substrate 8b is
Since it is located further outside the peripheral edge of the inspection port 6a, in this state, the lower edge of the lid 7 is inserted into the hanging piece 8c of the lower fixture 8 as shown by the arrow, and then the lid 7 is inserted.
The upper side of is pressed in the direction of the back plate 6. Then, as shown in FIG. 4, the lid 7 is brought into contact with the front surface of the back plate 6 so as to close the inspection port 6a. Next, as shown by the arrow in FIG. 4, when the upper fixture 8 is pushed down, the upper edge of the lid 7 enters the inside of the hanging piece 8c of the fixture 8, which causes the lid 7 to move. As shown in FIG. 2, the upper and lower edges are hooked by the hooking pieces 8c of the upper and lower fittings 8 and the inspection opening 6a is closed. At this time, the holding piece 8a is the hanging piece 8a.
Since it is formed longer than c, there is no fear that the sandwiched state with the back plate 6 will be released.

When it is necessary to remove the lid 7,
In the opposite of the above, the upper mounting member 8 may be pushed upward, which releases the hooked state of the upper edge of the lid 7. After that, the upper end of the lid 7 is pulled out to the front (inside of the cabinet), and then the lid 7 is pulled upward,
The hooked state between the lower part and the lower fixture 8 is also released, the lid 7 is removed from the back plate 6, and the inspection port 6a is opened.

As described above, the method of attaching the lid 7 of the inspection port 6a of the present invention is such that the edge of the back plate 6 having the inspection port 6a is clamped and can be attached to and detached from this edge. The lid 7 can be attached to the front surface of the back plate 6 and the inspection port 6a can be closed only by inserting it through the attachment 8.

In this embodiment, an example in which a lid is attached to the inspection port formed on the back plate of the washbasin is shown.
The inspection port to which the lid is attached by the method of the present invention or using the attachment of the present invention may be any inspection port formed on the plate body, and may be an inspection port such as a sink or a bath in addition to the washbasin. good.

In this embodiment, the upper and lower edges of the lid are hung by the upper and lower fittings, but the lid is hung on the back plate by this fitting and the inspection port is closed. For example, the lower end of the lid may be rotatably attached to the back plate using a hinge, and only the upper edge of the lid may be hung by this attachment. Although the embodiment shown in FIG. 1 shows an example in which the lid is attached to the back plate using four attachments, the width of the attachment is long enough to hold the lid without rattling. If it has, it may be used in a pair of upper and lower sides.

If the lid attached by this attachment may move laterally, a stopper or the like may be provided on one side of the hanging piece that hooks the edge of the lid.

Further, in the embodiment, a plate-shaped cover is shown as the cover to be attached by the method of the present invention, but the cover may be formed with an insertion hole for a drain pipe or the like,
This does not affect the gist of the present invention at all.

[0024]

As described above, in the method of mounting the inspection port lid according to the present invention, the mounting tool which is mounted while holding the edge of the back plate forming the inspection port is slid up and down, and is attached to the surface side of the mounting tool. The lid can be attached to the front surface of the back plate in a secure manner by simply hanging the edge of the lid with the protruding hanging piece, and the inspection port can be closed. This makes it easier to perform pipe connection work and subsequent maintenance when installing a wash basin or sink.

Further, in the fixture used in the method of the present invention, since the hooking piece on the front surface side is formed shorter than the sandwiching piece on the back surface side, the edge of the lid is hooked between the hooking piece and the substrate. Even when the mounting tool is slid so that it can be held, the state of the back plate sandwiched between the substrate and the sandwiching piece does not come off, and the lid is securely held by the back plate.

Further, it is not necessary to attach a reinforcing member for screwing around the inspection port or to provide a screw hole, and the work of screwing the lid at the time of shipping is also unnecessary. The productivity is improved and the cost is reduced.

Further, the fixture used in the method of the present invention is
Since it can be formed only by integrally molding synthetic resin or bending a metal plate, it does not require complicated processing requiring dimensional accuracy, it can be easily manufactured, and since it has flexibility, some dimensional error can be tolerated, It can be used to attach various inspection lids, resulting in cost reduction. In addition, the attachment strength is not likely to be lowered due to repeated attachment and detachment like a screw, and many excellent effects such as excellent durability and reliability are achieved.
