DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a construction in which gratings are hinged so that each grating is opened in the same direction in a continuous laying, and is particularly used in a place where the frequency of opening and closing such as a snow melting groove is high.

[0002]

2. Description of the Related Art Conventionally, there is a hinged structure in a water collecting basin lid in which one receiving frame is combined with one grating.

[0003]

SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for continuously laying gratings, particularly in a structure used for snowmelt grooves, etc., when the frequency of opening and closing of the gratings is high.
The treatment when the grating is opened is a problem, and a hinged structure for preventing the escape is provided, and obtaining the structure is a technical problem to be solved.

[0004]

The technical means for solving the above-mentioned problem is that one of the two receiving frames on which the grating is placed is provided with a hinge at an equidistant portion where each of the plurality of gratings is adjacent. A hinge fitting having a through hole through which a pin is inserted is erected, and a through hole is formed in each surface of the grating facing the hinge fitting, that is, an outer end member of the bearing bar, and adjacent to the bearing bar. Cut out the main part of at least one piece of wood (at the adjacent grating)
Each is connected by a hinge pin that penetrates adjacent gratings and hinge bearing hardware.

[0005]

According to the above-mentioned hinged grating, the hinge mounting portion, that is, the hinge receiving metal has no projecting portion outside the receiving frame, so that the receiving frame can be easily constructed, and the hinge pin is inserted into the receiving frame after the grating is disposed. In the work, the work is easy by notching the material adjacent to the outer end material of the bearing bar, and the opening angle can be selected around 150 degrees by using the hinge structure as a pin hinge. It is a safe configuration for use.

[0006]

An embodiment of the present invention will be described with reference to the drawings.
1, reference numerals 1 and 2 denote receiving frames on which the grating 3 is placed.
Is a hinge supporting hardware having a hinge pin insertion through hole 5 erected on the mounting surface of the receiving frame 1, A in the figure, a state in which the grating 3 has not been mounted, B in an open state, and C, a closed state. The state is shown in FIG.
1 is an enlarged detail of a portion D in FIG. 1, wherein reference numeral 6 denotes a bearing bar outer end material which constitutes the grating 3 and has a hinge pin insertion through hole 7, and 8 denotes a bearing bar outer end material 6 adjacent to the bearing bar outer end material 6. A bearing bar 10 having a notch 9 is a reinforcing member. In FIGS. 3 and 4, a hexagon bolt 11, a hexagon nut 12, and a double nut 1 constitute a hinge pin.
Alternatively, the pin 14 having the grooves 15 and 16 and the E-stop ring 17 may be used.

[0007]

As described above, according to the present invention, in the grating construction for continuous laying, conventionally, the grating is simply placed or fixed to the receiving frame with bolts, and the adjacent grating is adjacent to the grating. And share the hinge pin
Therefore, in use conditions in places where frequent opening and closing work such as snow melting grooves are performed, the trouble of attaching and detaching the bolt fixing portion is eliminated, grating escape at the time of lid closing is prevented, and the state at the time of lid opening is further improved. The arrangement is orderly and the opening angle is approximately 150 degrees in structure, so that the structure is safe, and furthermore, the whole construction work is easy and its practical effect is high.

Claims (1)

(57) [Claims] 1. One of two receiving frames on which grating is placed.
In the book, hinge supporting hardware having a through hole through which a hinge pin is inserted is provided upright at equidistant portions where the plurality of gratings are adjacent to each other, and bearings constituting respective surfaces of the grating which are in contact with the hinge supporting hardware. A through hole is also formed in the outer end member of the bar, through which the hinge pin is inserted, and at least one of the adjacent members of the bearing bar is cut out at a portion where the head of the hinge pin protrudes. A hinged grating characterized in that it is connected by a hinge pin which penetrates the grating and the hinge bearing hardware.
