DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage lid for closing an opening of a drainage trap.

[0002]

2. Description of the Related Art Conventionally, the opening of a drainage basin has generally been closed by dropping a lid made of a concrete block or a metal lattice into a lid receiving frame. However, when the lid is dropped, there is a problem that it is troublesome to handle the lid during inspection and cleaning of the drainage basin. In view of the above, a metal grid lid is pivotally attached to a lid receiving frame so as to be pivotable, and its handleability is improved. However, the pivotable lid may not be able to open and close the lid sufficiently depending on the installation location because there is another object such as a building on the pivotal locus of the lid.
In such a case, a drop-down type lid must be used, and inevitably, the manufacturer must prepare two types of drop-down type and pivot type lids, and inventory management becomes complicated. However, there is a problem that it is difficult to obtain a mass production effect. In addition, since the pivot type lid must be attached to the collecting and draining basin in a state where the lid body and the lid receiving frame are integrated, there has been a problem that the handling is heavy and troublesome and requires a great deal of labor. In addition, the pivotable lid pivots on the lid with a cantilever pin attached to the lid receiving frame, so when a large load is applied to the lid, the pin is easily bent, and if the lid is used for a long period of time, There was also a problem that the rattle was easily rattled and it was difficult to pivot the lid smoothly.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a lid for collecting and draining water, which can facilitate inventory control and reduce costs by mass production.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a hinge plate attached to one side of a lid body, in which an inverted U-shaped notch is formed downward and engaged with the notch. The drainage cover in which the hinge pin is stretched over a hinge box attached to the lid receiving frame is the invention of claim 1, wherein in the invention of claim 1, the drainage is drainage whose opening is regulated by a stopper. In the invention of claim 2, the lid for collecting and draining water is a back plate of a hinge box in which the stopper contacts the upper edge of the hinge plate. Alternatively, in the invention of the second or third aspect, the drainage / collecting lid provided with the hinge box outside the lid receiving frame is the invention of the fourth aspect, and the hinge box of the first, second, third, or fourth aspect of the invention is provided. Bottom The drainage and drainage lid having an inclined surface is the invention of claim 5, and the invention of claim 1 or 2 or 3 or 4 or 5 is the invention of the invention of claim 1 or 2 wherein the spacer is interposed on both sides of the hinge plate. Item 6 is the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1,
Reference numeral 1 denotes a double-opening lid. Each of the lids 1 has a main member 3 made of an I-shaped rope arranged at a fixed pitch between end plates 2 at both ends, and a plurality of auxiliary members 4 are arranged in parallel therebetween. In addition, it is a lattice-like structure in which the horizontal members 5 are arranged at a constant pitch orthogonal to the main member 3 and the auxiliary member 4. A base plate 6 is attached to the front and rear lower ends of the main member 3. Reference numeral 7 denotes a rubber packing attached to the lower surface of the base plate 6 for reducing the collision sound generated when the lid 1 is closed by the rubber packing 7. 8 is each lid 1
The hinge plate 8 is provided with an inverted U-shaped notch 9 which is engaged with a hinge pin 13 described later and is formed downward in the hinge plate 8.

[0006] Reference numeral 10 denotes a lid receiving frame to which the lid 1 is attached.
1 is formed in a square frame shape by a frame plate 12 formed on an opposing surface, and a hinge box 14 having hinge pins 13 stretched forward and backward on both sides is provided so as to protrude outward. The hinge box 14 is formed by fixing a U-shaped frame body to the notch opening 15 of the frame plate 12, and has a slope 17 having a bottom portion inclined toward the lid receiving frame 10. For this reason, dust and pebbles that enter from the upper part are discharged into the collecting and draining basin, and the hinge box 14 is removed.
Does not accumulate inside. Reference numeral 18 denotes a stopper for restricting the opening of the lid 1 to 110 degrees, and the stopper 18 is a hinge box 1 to which an upper edge of the hinge plate 8 abuts.
4 as a back plate 14a. Reference numeral 19 denotes a spacer made of rubber or resin, which is fitted on both sides of the hinge pin 13 by opening the slits thereof, and is made of rubber or resin. This is for opening and closing the lid 1 smoothly without rattling.

[0007] In the construction of the drainage basin, the rebar constructed in the form is firstly provided with
After the anchor of the lid receiving frame 10 (not shown) is welded, concrete is cast, and the lid receiving frame 10 is attached to the collecting and draining basin. After the concrete has hardened, the lids 1 and 1 are set on the lid receiving frame 10. The set of the lids 1 and 1 has an inverted U-shaped notch 9 of a hinge plate 8 and a lid receiving frame 1.
It is completed by dropping from above so as to engage with the hinge pins 13 of the hinge box 14 formed on the left and right of the zero. After the lids 1 and 1 have been attached to the collecting and draining basin in this way, when checking and cleaning the collecting and draining basins, use the hooks or special tools to attach the center of the lids 1 and 1 When lifted, the left and right lids 1, 1 are pivotally opened about the hinge pins 13 of the hinge box 14 with which the hinge plates 8 are engaged, and are opened. The edge is in contact with the upper edge of the back plate 14a of the hinge box 14, and the hinge box 14 is double-opened with a 110-degree opening as shown in FIG.

At the time of this opening operation, the hinge plate 8 is held by the spacer 19 fitted to the hinge pin 13, so that the lids 1 and 1 can be opened smoothly without peeling. Then, inspection and cleaning of the collecting and draining basin may be performed through the opening and closing of the collecting and draining basin in which the lids 1 and 1 are double-opened. At this time, the notch 9 of the hinge plate 8 of the lids 1 and 1 is substantially horizontal and is in contact with the back plate 14a as the stopper 18, so that the lids 1 and 1 do not come off. You can work safely. When the drains are installed in a place where the lids 1 and 1 cannot hit each other and cannot be opened, do not pivot the lids 1 and 1, When pulled up, the notch 9 engaged with the hinge pin 13 is in a downward state, so the notch 9 of the hinge plate 8 engaged with the hinge pin 13 is pulled out of the hinge pin 13 and the left and right lids Since items 1 and 1 are to be removed, inspection and cleaning of the drainage basin may be performed through the opened opening.

In the preferred embodiment, the hinge box 14 extends outside the lid receiving frame 10 to reduce the gap formed between the lids 1, 1 and the lid receiving frame 10. , May be formed in the lid receiving frame 10.
Also, the bottom of the hinge box 14 is an inclined surface 17 and
Although dust and pebbles can be discharged therefrom, when the hinge box 14 is formed in the lid receiving frame 10, the bottom may be opened. Further, in the preferred embodiment, the lids 1 and 1 are double-opened, but it is needless to say that the lid 1 may be one-sided with one lid. Further, although the lid 1 has a lattice shape, it is needless to say that the lid 1 may have a plate shape.

[0010]

As apparent from the above description, the present invention provides a hinge plate provided with an inverted U-shaped notch on a lid, and a hinge pin engaged with the notch of the hinge plate and a hinge of a lid receiving frame. Since it is stretched over the box, the opening of the drainage basin can be opened by pivoting the lid or by pulling it upwards. Since installation and construction can be performed, design and construction work becomes extremely easy. Moreover, since the lid and the lid receiving frame can be separated, the lid is lighter than a conventional rotary type that cannot be separated, and does not require labor for carrying and construction. In addition, since the hinge pin is pivotally supported on both sides by the hinge box, the hinge pin does not bend even when a large load is applied to the lid, and the hinge pin can be prevented from rattling even after long use. Thus, the lid can be opened and closed smoothly over a long period of time. Moreover, when the lid is opened, the notch of the hinge plate is substantially horizontal, so that the hinge plate does not come off from the hinge pin, and the lid does not come off during the operation, which is extremely safe.

Further, by providing the stopper of the lid as the back plate of the hinge box as in the third aspect, it is not necessary to separately provide a stopper, so that the structure can be made simple and inexpensive. Furthermore, by forming the hinge box outside the lid receiving frame as in claim 4, the gap generated between the lid on the pivot side and the lid receiving frame can be made small, and the design can be improved. In addition to improving the performance, it is possible to reduce the room for pebbles and the like to enter the gaps and prevent the occurrence of open / close failure. In addition, by forming the bottom of the hinge box with an inclined surface as described in claim 5, it is possible to reliably prevent dust and pebbles from accumulating in the hinge box and causing the pivoting failure of the lid. Further, as in claim 6,
By interposing a spacer between the hinge pins to which the hinge plate is engaged, the rattle of the lid can be suppressed and the opening / closing operation can be smoothly performed. Therefore, the present invention is extremely large in that it contributes to the development of the industry as a drainage and drainage lid that solves the conventional problems.
