Normally, the underground structure is constructed of concrete, etc., but in order to improve the tightness of the lid and protect the concrete surface of the opening, the receiving frame made of the same cast iron should be attached to the opening. Since it is attached and used to fit into the receiving frame, the lid plate and the receiving frame are manufactured as one set.

が望まれている。The lid for the underground structure is made of a lid plate and a receiving frame and attached, but when the lid plate is locked to the receiving frame with a hinge, etc., the lid plate should be opened at an angle of about 110 degrees with respect to the ground surface. However, in the case of a disk-shaped lid plate, the diameter is 3
Except when the weight is 0 cm or less, the lid plate is heavy, so use a special hinge or the like and rotate it 180 degrees and put it on the ground surface with the back side up, or lift the lid plate and rotate it horizontally to contact the ground surface. It was usual to open it and perform work. Therefore, when the cover plate is opened, it is necessary to install a moving shelf around the opening of the underground structure to prevent danger, and it is necessary to lift and close the cover plate placed on the ground surface again. It was a job that involved me. In order to solve these inconveniences, the emergence of a product that can hold a disc-shaped lid plate at an angle of about 110 degrees with respect to the ground surface, particularly when the lid plate is opened, is desired.

Locking projections of the two brackets parallel to the center line of the receiving frame and arranged at equal intervals from the center line. This is solved by projecting two locking pieces so that they are located inside parallel arms. Therefore, inside the arm projecting portion of the light-handed metal fitting of the receiving frame, there is provided a hole into which the locking piece protruding from the outer wall of the lid plate is inserted when the lid plate is fitted to the receiving frame.

When opening the lid plate 1 on the inner wall surface, it is preferable to project a strip 10 that supports the locking pieces 3 and 3 of the lid plate 1. Also, the locking pieces 3 and 3 of the lid plate 1 are as shown in FIG. It does not matter if it is bent downward so that it projects from the lower end of the outer wall of the lid plate 1. In addition, the locking fitting 4 of the receiving frame 2
The carrying rack 8'of the cover plate 1 located between the arms 5 and 5 is preferably inclined downward.
