Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for fixing a lid in a U-shaped groove, a drainage ditch, etc.

(Prior Art) Conventionally, the lid of this type of U-shaped groove, drain, etc. was simply fitted onto the upper part of the U-shaped groove, drain, etc. Gaps often formed and caused instability, which caused noise due to jumping and rattling.
On the other hand, in cases where the lid is directly fixed to a U-shaped groove, drainage ditch, etc. with a fixing device such as a bolt or nut, this fixing device may wear out due to the passage of vehicles, etc. It is difficult to unfit and disengage, making it impossible to clean the U-shaped groove and the drainage area, and a solution to this problem has been desired.

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned viewpoints, and in particular, the present invention has a simple structure to provide a lid body that is closed at the top of a U-shaped groove, a drain, etc. It is an object of the present invention to propose a fixing device for a lid that closes the upper part of a U-shaped groove, a drainage ditch, etc., which can be securely fixed and supported.

(Means for Solving the Problems) As a technical means for solving the above-mentioned problems, the fixing device for a lid body that closes the upper part of a U-shaped groove, a drainage ditch, etc. according to the present invention has a U-shaped groove, It is characterized in that a pressing contact member is provided via an elastic member on the outer surface of a support piece formed on the back surface of a lid body that closes the upper part of a drainage ditch or the like.

(Operations and Effects of the Invention) As in the above configuration, by providing the pressing abutting member on the outer surface of the support piece formed on the back surface of the lid body via the elastic member, the pressing abutting member is attached to the elastic member. Therefore, the state of being pressed outward is maintained at all times. Therefore, when this lid body is closed on the upper part of a U-shaped groove, a drain groove, etc., the above-mentioned pressing contact member is firmly attached to the inside back surface of the U-shaped groove or drain groove, causing it to wobble or jump up. etc., noise is eliminated, and installation is also simple.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral A indicates a U-shaped groove main body, and this U-shaped groove main body A is formed by the lid 1 and the U-shaped groove 12.

The lid 1 has a pair of support pieces 2, 2 formed on the outside in the longitudinal direction of the back surface thereof, and bolts 3, 3 and nuts 4, 4 are attached to the support pieces 2, 2.
A fixing device 5, 5 consisting of is attached. The bolts 3, 3 of the fixing devices 5, 5 are connected to the support pieces 2,
2 is loosely inserted into the elongated holes 6, 6. Pressing contact members 7, 7 are fixed to the heads of the bolts 3, 3, and the surfaces of the pressing contact members 7, 7 narrow downward from the top when viewed from the side. It is formed at an angle. Reference numerals 8, 8, . . . indicate uneven rough surface portions formed on the surfaces of the pressing contact members 7, 7. Note that the rough surface portions 7, 7 are not limited to this, and may have the shapes shown in FIGS. 4a to 4d, for example. Reference numerals 9 and 9 indicate elastic members made of coil springs that are fitted into portions of the bolts 3 and 3 attached to the support pieces 2 and 2, which are located outside of the support pieces 2 and 2; , 10 indicate receiving bolts for the elastic members 9, 9 which are screwed onto the heads of the bolts 3, 3.

The U-shaped groove 12 has L-shaped notches 13, 13 extending inward from the center of the upper surface of both side walls.
is cut out. And this notch 13,1
L-shaped protective fittings 14, 14 are installed on the upper surface of the protective fittings 14, 14, and support protrusions 15, 15 integrally provided on the bottom surfaces of the protective fittings 14, 14 are provided inside the both side walls of the U-shaped groove 12. It is buried in. Thereby, the protective fittings 14, 14 can be reliably fixed to the notches 13, 13 of the U-shaped groove 12.

The fixing device for the lid that closes the upper part of the U-shaped groove, drainage ditch, etc. is constructed as described above. The lid body 1 is fitted into the parts 13, 13, and the upper part of this U-shaped groove 12 is closed. In this case, the pressing contact members 7, 7 of the fixing devices 5, 5 provided on the support pieces 2, 2 on the back surface of the lid body 1 are brought into abutment engagement with the inner surface of the side wall while being slightly pressed inward. ,
Since they are always urged outward by the elastic force of the elastic members 9, 9 made of coil springs, their close contact can be ensured, thereby preventing accidental disengagement. It can be prevented. As described above, the fixing device for the lid that closes the upper part of the U-shaped groove, drain, etc. has a simple structure, so it is easy to manufacture and an inexpensive product can be obtained. Further, when the lid 1 is fitted into the upper part of the U-shaped groove 12, the pressing contact member 7 of the fixing device 5, 5 provided on the back surface of the lid 1,
7 is always urged outward by the elastic force of the elastic members 9, 9, and is maintained in close contact with the inner surfaces of both side walls of the U-shaped groove 12. It is safe because it eliminates rattling, prevents noise, and prevents accidental disengagement.

In addition, although the above-mentioned embodiment described in detail the fixing device for the lid body in the U-shaped groove, the device is not necessarily limited to the U-shaped groove.
