Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lid for collecting and draining water that closes the opening of the drainage and drainage tank.
[0002]
[Prior art]
Conventionally, the opening of the drainage drain was generally closed by dropping a lid made of a concrete block or a lid made of metal lattice into a lid receiving frame. However, when the lid is dropped, there is a problem that the handling of the lid is troublesome when checking and cleaning the drainage drain. In view of this, a product with improved handleability by pivotally attaching a metal grid lid to the lid receiving frame has been commercialized. However, the pivot type lid may not be able to fully open and close because there are other objects such as buildings on the pivot locus of the lid depending on the installation location. In such a case, a drop-in type lid must be used, and the manufacturer must prepare two types, a drop-in type and a pivot type lid, and inventory management becomes complicated. There was a problem that it was difficult to obtain a mass production effect. In addition, since the pivot type lid must be attached to the drainage with the lid body and the lid receiving frame integrated, there is a problem that it is heavy and cumbersome and requires a lot of labor. In addition, the pivoting lid is pivotally attached by a cantilevered pin attached to the lid receiving frame, so if a large load is applied to the lid, the pin will bend easily and the pin will be bent over a long period of use. There was also a problem that it was difficult to rattle and it was difficult to smoothly pivot the lid.

Reference numerals 1 and 1 denote double-open lids, and each lid 1 has a main member 3 made of an I-shaped rope arranged at a constant pitch between end plates 2 and 2 at both ends, and a plurality of auxiliary members 4 therebetween. Are arranged in parallel, and the cross member 5 is arranged in a lattice shape orthogonal to the main member 3 and the auxiliary member 4 at a constant pitch. 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 that is attached to the lower surface of the base plate 6, and reduces the impact sound that is generated when the lid 1 is closed by the rubber packing 7. Reference numeral 8 denotes a hinge plate that is attached to the front and back sides of each lid 1, and the hinge plate 8 is formed with an inverted U-shaped notch 9 that is engaged with a hinge pin 13 described later.
[0006]
Reference numeral 10 denotes a lid receiving frame to which the lid body 1 is attached. The lid receiving frame 10 is formed in a square frame shape by a frame plate 12 having an inner flange portion 11 for receiving the lower end surface of the lid body 1 formed on an opposing surface, and on both sides. A hinge box 14 with a hinge pin 13 stretched before and after is extended outward. The hinge box 14 has a frame body 12 having a U-shaped cross section fixed to a notch opening 15 of the frame plate 12, and a bottom portion of the hinge box 14 has an inclined surface 17 inclined toward the lid receiving frame 10 side. For this reason, dust, pebbles and the like entering from the upper part are not discharged into the drainage and are not accumulated in the hinge box 14. Reference numeral 18 denotes a stopper for restricting the opening degree of the lid 1 to 110 degrees. The stopper 18 is a back plate 14a of the hinge box 14 with which the upper edge of the hinge plate 8 abuts. Reference numeral 19 denotes a rubber or resin-made elastic spacer that is fitted on both sides of the hinge pin 13 by opening the slit, and the spacer 19 is provided on the left and right sides of the hinge plate 8 engaged with the hinge pin 13 and the hinge box 14. This is to narrow the gap formed between the side surfaces and smoothly open and close the lid 1 without rattling.
[0007]
First, when constructing a collection and drainage machine, the structure constructed in this way is welded with an anchor of a cover receiving frame 10 (not shown) to a reinforcing bar assembled in a mold, and then casted into a concrete, Attach the frame 10 to the drainage drain. Then, after the concrete is hardened, the lids 1 and 1 are set on the lid receiving frame 10. The setting of the lids 1 and 1 is completed by dropping from above so that the inverted U-shaped notches 9 of the hinge plate 8 are engaged with the hinge pins 13 of the hinge box 14 formed on the left and right of the lid receiving frame 10. To do. In this way, when the lids 1 and 1 are attached to the drainage drainage, the central part of the lids 1 and 1 is used with a hook or a special tool when checking or cleaning the drainage drainage. When pulled up, the left and right lids 1 and 1 are pivoted and opened around the hinge pin 13 of the hinge box 14 with which the hinge plate 8 is engaged, The edge is abutted on the upper edge of the back plate 14a of the hinge box 14 and is double-opened in the form of a double door at an opening of 110 degrees as shown in FIG.
[0008]
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 are opened smoothly without being peeled off. And what is necessary is just to inspect and clean in the collection / drainage through the opening of the collection / drainage which the lids 1 and 1 are opened in a double-spreading manner. At this time, the notch 9 of the hinge plate 8 of the lid 1, 1 is substantially in the horizontal direction and is in contact with the back plate 14 a as the stopper 18, so that the lid 1, 1 does not come off. You can work safely. In addition, when a drainage collector is installed in a place where the lids 1 and 1 cannot collide with other objects, the lids 1 and 1 can be moved upward without being pivoted. When pulled up, the notch 9 engaged with the hinge pin 13 is in a downward state. Therefore, the notch 9 of the hinge plate 8 engaged with the hinge pin 13 is extracted from the hinge pin 13, and the left and right lids Since 1 and 1 are removed, inspection and cleaning in the drainage can be performed through the opened opening.
[0009]
In the preferred embodiment, the hinge box 14 is extended outward from the lid receiving frame 10 to reduce the gap formed between the lids 1, 1 and the lid receiving frame 10. It may be formed in the frame 10. Moreover, although the bottom of the hinge box 14 is used as the inclined surface 17 so that dust, pebbles, etc. can be discharged, when the hinge box 14 is formed in the lid receiving frame 10, the bottom may be opened. . In the preferred embodiment, the lids 1 and 1 are double-opened, but it is needless to say that the lid 1 may be single-opened. Furthermore, although the lid 1 has a lattice shape, it is needless to say that it may have a plate shape.
[0010]
【The invention's effect】
As is apparent from the above description, in the present invention, a hinge plate provided with an inverted U-shaped notch is provided on the lid, and a hinge pin engaged with the notch of the hinge plate is stretched over the hinge box of the lid receiving frame. Since the opening of the drainage drainage can be opened by pivoting the lid or by opening it upward, it can be freely installed without distinguishing it from the rotary type or the drop-in type depending on the installation location. Design and construction work are extremely easy. Moreover, since the lid and the lid receiving frame can be separated, they are lighter than the conventional rotary type that cannot be separated, and no labor is required for carrying and construction. In addition, since both sides of the hinge pin are pivotally supported by the hinge box, the hinge pin will not bend even if a large load is applied to the lid, and it will be possible to prevent the hinge pin from rattling even after long-term use. The lid can be opened and closed smoothly over a long period of time. In addition, when the lid is opened, the notch of the hinge plate is substantially lateral, so that the hinge plate does not come off from the hinge pin, and the lid does not come off during work, which is extremely safe. Further, by providing a spacer between the hinge plate and the hinge box, it is possible to suppress the rattling of the lid and smooth the opening / closing operation.
[0011]
Further, as described in claim 3, by using the stopper of the lid as the back plate of the hinge box, it is not necessary to provide a separate stopper, and the structure can be simple and inexpensive. Furthermore, as in claim 4, by forming the hinge box outside the lid receiving frame, the gap generated between the lid on the pivot side and the lid receiving frame can be made small. In addition to improving the performance, it is possible to prevent the occurrence of opening and closing defects by reducing the room for pebbles and the like to enter the gap. Furthermore, as according to claim 5, by an inclined surface of the bottom portion of the hinge box, Ru can be reliably prevented to deposited dust and pebbles in the hinge box generating defective pivoting of the lid etc It has various advantages.
Therefore, the present invention contributes to the development of the industry as a lid for collecting and draining water that has solved the conventional problems, and is extremely large.
