[0005]

1 to 4 show a first embodiment of a lid hinge device for a water control valve casing according to the present invention, in which a frame body 10 has a substantially cylindrical shape and an upper end thereof has an opening 11. The portion constitutes a lid receiving frame. The lid 12 is for closing the opening 11 so as to be openable and closable, and the lid 12 is reversibly attached to the frame 10 by a lid hinge device provided between an edge of the opening 11 and the inside of the opening 11.

Hinge plate 1 for reversing the lid 12
3 is formed of a material having elasticity into a plate shape having a required length. As the material of the hinge plate 13, rubber or a synthetic resin having elasticity similar to rubber is suitable. In the embodiment, silicon rubber is used and is molded to have the following structure.

That is, the hinge plate 13 and the lid 1 are attached to one end of the hinge plate 13.
The first shaft portion 14 for connecting the second shaft 19 is integrally provided, and the mounting portion 15 for the second shaft 19 for connecting the hinge plate 13 and the frame body 10 is provided at the other end portion. . The illustrated first shaft portion 14 projects to the left and right of the upper end portion of the hinge plate 13, and has an integral structure that is molded at the same time when the hinge plate 13 is molded.

Since the second shaft 19 is used as a retaining member, a horizontal hole is formed at the lower end of the hinge plate 13 as a mounting portion 15, and the second shaft 19 is inserted thereinto from the rear. Since the first shaft 14 is provided and the mounting portion 15 of the second shaft 19 is provided, both ends of the hinge plate 13 are made larger than the plate-shaped portions. The enlarged portion 17 of the inner upper end is used as a locking portion for preventing the first shaft portion 14 from coming out after inserting the first shaft portion 14 into the shaft supporting portion 16 from the inside of the lid. The lid 12 such as a small water control valve casing or a sewage basin is usually made of cast iron, but since it is relatively lightweight, the hinge plate 13 may be made of rubber in most cases. However, if necessary, a core material can be conveniently used for each shaft portion or the like to increase the strength.

A pair of left and right shaft support portions 16 are provided on the lower surface of the edge portion of the lid body 12 with the insertion opening 16a facing inward.
The pair of shaft supporting portions 16 and 16 are provided at intervals corresponding to the width of the plate-shaped hinge plate 13, and the pair of first shaft portions 1 is provided therein.
4, 14 are inserted inward from the insertion openings 16a, 16a. In the enlarged portion 17 between the shaft support portions 16, the enlarged portion 17 is cut left and right at a position facing the lower surface of the lid body 12 when the hinge plate 13 is in a state of being substantially horizontal, and the flat portion 17a is formed. To form. This flat portion 17a is the hinge plate 1
The hinge plate 13 is brought close to the lower surface of the lid so that the first shaft portion 14 can pass through the narrow path between the insertion openings 16a only when the 3 is substantially horizontal. The portion between the insertion ports 16a is
It is a protrusion 20 that forms a bottleneck that prevents the first shaft portion 14 from slipping out when the first shaft portion 14 passes therethrough and assumes a posture other than horizontal. However, the flat portion 17a is not essential, and the hinge plate 13 can be attached to the shaft support portion 16 by pushing it in due to the elasticity of the enlarged portion.

A through hole 18 into which the other end of the hinge plate 13 is inserted is provided inside the opening 11 of the frame body 10 so as to project in a U-frame shape. The width of the through hole 18 is the width of the hinge plate 13. Slightly larger. The lower portion of the hinge plate is inserted therein, and the second shaft 19 is inserted into the attachment portion 15 at the lower end to be attached.
The illustrated shaft 19 utilizes bolts and has a nut 1
9a is screwed to prevent it from coming off.

[0011] Figure 5 below, shows a second embodiment of the engaging Ru equipment to the present invention. In this example, the first shaft portion 14 is provided at one end of the hinge plate 13, and the enlarged portion 17 is provided between them in a cylindrical shape. Bloated part when inserting the first shaft portion 14 into the insertion opening 16a of the shaft support 16, and elastic deformation by elasticity, and restoration to the first shaft portion 14 intrudes into the insertion opening 16a To prevent it from slipping out.

Further, the lower end of the hinge plate 13 provided with the mounting portion 15 for the second shaft 19 is a protrusion 15 which is projected to the left and right.
A and 15a are used to make the retainer using bolts and nuts more complete. When the hinge plate 13 is inserted into the through hole 18, the protrusion 15a is deformed and pushed in.

As the material of the hinge plate 13 used in each embodiment, a relatively hard material is suitable among the above rubbers or synthetic resins having elasticity similar to rubber.

The lid hinge device constructed as described above can be easily inverted by the elasticity of the hinge plate 13 when the lid 12 is removed from the opening 11, and when the lid 12 is closed, Even if it comes into contact with a water control valve or the like installed in the frame body 10, the hinge plate 13 has elasticity so that it is easily deformed, and the enlarged part 17 causes the hinge plate 13 to slip out of the shaft stopper 16. Prevent.

[0015]

Since the present invention is constructed and operates as described above, it does not disturb the lid 12
You can smoothly open and close the
Moreover, there is an effect that the lid body 12 does not come off during opening and closing. Especially in the device of the present invention, the inside of the lid 12
A pair of shaft support portions 16 each having an insertion opening 16a directed toward
16 is provided on the lower surface of the edge portion of the lid body 12, and the first shaft portion 14 is
By elastically deforming the insertion opening 16a from the inside of the lid
After that, insert it into the shaft support 16 and restore it after insertion to prevent it from coming out.
Enlarged portion that is made larger than the insertion opening 16a for cutting
Since 17 is formed at one end of the hinge plate 13, the hinge plate
Simple work of inserting one end of 13 into the insertion part 16
Can be attached to the lid 12 with
There is a feature that it can be easily replaced.
