Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a grating lid with an opening/closing auxiliary device.

(Prior Art) Conventionally, grating covers have been used in places that require opening and closing, such as public ditches, mini-community ditches, and drifting snow ditches. For example, in the case of drifting snow ditches, the snow input port is large, so a heavy grating lid is used, and as a result, it is very difficult to open and close the lid manually, so a gas spring is used to constantly bias it in the opening and closing direction. There is a grating cover for the drifting snow gutter to assist with this.

When in use, it is necessary to open the grating lid at an angle of 90 degrees or more to allow a large amount of snow to fall into the groove and make it easier to wash away. To do this, the mounting end of the gas spring on the frame side must be pivoted inward from the fixed frame. In addition, an application has been filed in which a gas spring is pivoted to a fixed frame via a swing bracket so that when the groove is closed, the gas spring is compressed using the wall surface of the groove as a reaction force.

However, the grating lid is simply placed on the gutter of the secondary concrete product, and naturally there are clearances and manufacturing errors, and using the concrete wall surface as a reaction force is not preferable for reliability.

In order to adjust this, it is necessary to change the mounting position of the cylinder of the gas spring fixed to the lid side, which not only makes the work extremely complicated, but also requires the use of such an adjustable structure. The disadvantage of doing so was that it was expensive.

(Problems to be solved by the invention) Therefore, this invention was devised in order to eliminate the above-mentioned drawbacks.In other words, even when a secondary concrete product is placed on a side gutter, it can always be reliably maintained. To provide a grating for a drifting snow gutter with an opening/closing device whose lid can be tightly closed.

[Structure of the idea]

(Means for Solving the Problems) Hereinafter, an embodiment of this invention will be described with reference to the drawings. , one end of the grating 1 is pivotally mounted, a bracket 5 having a stopper 5a is provided on the raising member 3 located at the lower part of the receiving frame 2, one end of a rotating bracket 6 is pivotally coupled to the bracket 5, and the rotating bracket is The other end of 6 is pivotally attached to the rod attachment end 7a of gas spring 7, and the cylinder attachment end 7b of gas spring 7 is pivotally attached to the other end of grating 1, so that when grating 1 is closed, rotation is prevented. It is characterized in that the bracket 6 is received by a stopper 5a.

Reference numeral 4 designates a snow cutter attached to the raising member 3, which is used to cut the snow thrown into the groove into an appropriate size.The shapes of the bracket 5 and the rotating bracket are shown in FIG. It may be formed as follows.

[Effect of idea]

According to this invention, when the grating 1 is closed, the gas spring 7 contracts, but in this case, the gas spring 7 is received by the stopper 5a of the bracket 5 via the rotating bracket 6, and as a result, the grating is accurately closed, so that the gutter of the secondary concrete product is closed. Even if this invention is mounted and used, the cratering lid can be opened and closed regardless of clearance or manufacturing error, and has extremely beneficial effects.
