Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for closing a drain of a gutter covering a top surface of a gutter formed along a road surface. 2. Description of the Related Art Conventionally, gutters formed along a road surface,
In order to cover the upper surface of the drain, a number of square groove covers mainly made of concrete are laid on the upper surface of the groove. As shown in FIG. 1, an elongated hole C for engaging a claw such as a hand or a lift hanger at the time of construction and draining rainwater or accumulated water at the time of rain as shown in FIG. Are formed between adjacent groove lids. [0003] However, the drainage port C catches a pedestrian's toe or a child's foot, a heel of a high heel fits in, or a small front wheel of a wheelchair for a disabled person. There is a problem in that falling leaves and garbage fall into the ditch from the drain port while being dangerous. SUMMARY OF THE INVENTION Accordingly, it is a main object of the present invention to provide a cap which can be easily attached to and detached from a drain port of a groove lid, and which has a simple structure and can be manufactured at low cost. [0005] To achieve the above object, the present invention takes the following technical measures. That is, the cap according to the present invention is a cap for closing the drain port C formed between the adjacent groove lids B, B,
A flat top plate 1 having an area sufficient to close the drain port C and having a small hole 1a for draining the water; A leg member 2 and a hook piece 3a which is incorporated so as to be movable only in the vertical direction along the leg member 2 and has a hook piece 3a at its lower end bent in a direction perpendicular to the length direction of the top plate 1. The top plate 1 includes a mounting piece 3 and a bolt 4 for moving the holding piece 3 up and down.
A fitting portion 4a is formed on the upper surface of the top plate 1 so as to be held therein and to be fitted with a tool for rotating the bolt 4. The leg member 2 and the holding piece 3 guided by the fitting portion 4a The vertical portion 3b is formed in such a size that it can rotate in the drain port C. DESCRIPTION OF THE PREFERRED EMBODIMENTS The top plate 1 and the sandwiching piece 3 are preferably made of a metal material such as stainless steel or rust-proofed iron, but a synthetic resin material having sufficient strength is used. It may be. The small drain hole 1a formed in the top plate 1 is formed as a small hole such that the heel of the high heel does not fit. The vertical movement range of the holding piece 3 due to the rotation of the bolt 4 is determined by the thickness of the corresponding groove cover B.
Since the thickness of the concrete groove cover is usually 7 cm to 15 cm, it is preferable to set the moving range so as to be applicable to all these groove covers. An embodiment of the present invention will be described below with reference to FIGS. In the drawings, reference numerals B and B are concrete groove covers laid in order to close an upper surface opening of a groove formed on the side of a road or the like, and are generally known.
An elongated drain port C is provided at an adjacent edge of the groove lids B. The present invention relates to a cap for closing the drain port C, which has a sufficient area for closing the drain port C, and has a rectangular flat top plate 1 having a small hole 1a for draining water. And a leg member 2 suspended downward from a central lower surface of the top plate 1 is fixed to the top plate 1. The leg member 2 has a slide groove 2a opened downward, and a holding piece 3 is incorporated along the slide groove 2a so as to be movable only in the vertical direction.
The holding piece 3 is screwed to a bolt 4 suspended from the top plate 1, and has a structure that moves up and down by rotating the bolt. The bolt 4 is held by the top plate 1 so as to be rotatable only, and a fitting portion 4 a into which a tool for rotating the bolt 4 is fitted is exposed on the top plate 1. At the lower end of the holding piece 3, hook pieces 3a bent in a direction perpendicular to the length direction of the top plate 1,
3a are formed. Further, the leg member 2 and the vertical portion 3b of the holding piece 3 sliding along the slide groove 2a thereof are formed to have a size capable of freely rotating in the drain port C. The material of the cap, particularly the top plate 1 and the sandwiching piece 3, is preferably a metal material such as stainless steel or rust-proof iron. However, it is also possible to mold with a synthetic resin material as long as it has sufficient strength. Also,
It is preferable to form a large number of small holes 1a for drainage formed in the top plate 1 with small holes that do not fit the heels or the like of the high heel. When the cap constructed as described above is attached to the drain port C, the direction connecting the hook pieces 3a, 3a of the sandwiching piece 3 is matched with the length direction of the drain port C as shown in FIG. Insert the hook pieces 3a, 3
The top plate 1 is rotated by 90 degrees as shown in FIG. 3 in a state in which a protrudes below the groove lids B, B. In this rotated position, the length of the hook pieces 3a is set in advance so that the tip portions of the hook pieces 3a, 3a sufficiently engage with the lower surfaces of the adjacent groove covers B, B. Next, a predetermined turning tool is inserted into the bolt fitting portion 4a exposed on the upper surface of the top plate 1 from the state of FIG.
The holding piece 3 is raised, and the groove cover B is held between the hook pieces 3a, 3a and the top plate 1, so that the cap can be firmly fixed. The vertical movement range of the holding piece 3 due to the rotation of the bolt 4 is determined by the thickness of the corresponding groove cover B. Since the thickness of the concrete gutter is 7 cm to 15 cm, it is preferable to set the moving range so that it can be applied to all these gutters. Although the representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the above-described embodiment structure alone, and may be appropriately modified within the range having the constituent requirements and the effects. Of course, it can be implemented. Since the cap of the present invention is constructed as described above, the cap can be attached only by inserting it into the drain port, rotating it by 90 degrees, and tightening one bolt. Thus, the mounting operation can be simplified and the running cost can be reduced. In the attached state, since the groove lid is firmly clamped between the hook piece of the clamping piece and the top plate, there is an effect that the top plate does not shift or rotate during use. .
