Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixture for attaching a safety light to a fence at a construction site.

[0002]

[Prior art]

 Conventionally, flashing safety lights that use dry batteries have been used at road construction sites, etc., but the batteries are exhausted quickly, and it is troublesome to operate the power switch in the morning and evening. Therefore, instead of the battery type, the solar type safety light 1 is used in some parts. This will be explained with reference to FIG. 1. A mushroom-shaped plastic case 2 has a solar cell 3 housed in an umbrella portion 2a and a storage battery 5 stored in a handle portion 2b. The light emitting element (LED) 6 is housed so that light is emitted from around the umbrella 2a.

In the safety lamp 1, the electric power obtained from the solar battery 3 is stored in the storage battery 5 when it is bright in the daytime, and when the surroundings become dark, the LED 6 blinks by the electric power supplied from the storage battery.

[0004] Such solar type safety lights have been taken away from the construction site due to their rarity, and there has been a demand for anti-theft measures.

[0005]

[Problems to be solved by the device]

 The present invention provides a device for attaching a safety light to a fence so that it cannot be easily stolen.

[0006]

[Means for Solving the Problems]

 The safety light fixture of this invention fixes the tubular body to the clamp, inserts the handle portion of the mushroom-shaped safety light into this tubular body, and secures the screw hole formed on the tubular body with a socket such as a hexagonal hole. The screw is screwed in and the safety light is tightened at the tip of the set screw.

[0007]

[Action]

 To remove the security light, you need a wrench that fits into the socket for the setscrew, and the prankster usually doesn't have such a thing, so it won't be stolen easily.

[0008]

【Example】

 This fixture is made of metal and, as shown in FIGS. 1 and 2, comprises a pipe clamp 10 and a tubular body 11 welded thereto. A screw hole is formed in the cylindrical body 11, and a set screw 12 is screwed into this. The set screw 12 has a hexagonal socket 12a at the head. Insert the handle portion 2b of the mushroom-shaped safety light 1 into the cylindrical body 11, insert a wrench 13 as shown in FIG. Tighten it so that it does not come off.

The pipe clamp 10 is the same as that used when assembling an iron pipe construction scaffold, and has a pair of jaws 15 pivoted to each other, and a crotch 16 is formed at the tip of the upper jaw 15a. A bolt 17 is rotatably attached to this with a pin 19. A bracket 20 is extended from the tip of the lower jaw, and a U-shaped notch 21 for engaging the bolt 17 is formed in the bracket 20.

The jaw 15 of the clamp 10 holds the lateral pipe 22 such as a fence, the bolt 17 is engaged with the bracket 20 of the lower jaw, and the nut 23 is tightened, so that the safety light 1 can be set. .

However, such a clamp does not prevent theft because it can be easily removed by removing the nut 23. Therefore, a screw hole is formed in the crotch portion 16 of the upper jaw, and a set screw 25 with a socket is screwed into this. This set screw is similar to the set screw 12. The head of the bolt is provided with a hole 26 into which the tip of the set screw 25 is engaged. If the setscrew 25 is tightened after mounting the clamp, the tip of the set screw enters the hole 26 in the head of the bolt, and the bolt 17 does not rotate largely. Therefore, the bolt 17 cannot be removed from the bracket 20 of the lower jaw only by loosening the nut 23, and the clamp cannot be removed after all.

Since a general person does not have a special tool such as the hexagonal wrench 13, the set screw 25 cannot be removed. Therefore, the clamp 10 cannot be removed. Of course, the set screw 12 with the tubular body cannot be loosened, so the safety light 1 cannot be removed from the fixture. It should be noted that a tape may be wound around the tubular body 11 in order to hide the set screw 12 with the tubular body.

In the above embodiment, the set screw is provided to prevent the bolt from rotating, but it is also possible to prevent the lower jaw from opening. FIG. 3 shows an example thereof. A set screw 30 is screwed into the upper jaw, and the tip of the screw is put into a hole 31 formed in the lower jaw.

5 and 6 show a vertical pipe 40 such as a column. The clamp 41 is composed of a pair of left and right arcuate strips 42 joined by a hinge, and the tips of the strips are fastened with bolts 43 and nuts 45. A semi-circular plate 46 is welded to the tip of one strip of the clamp, and a cylinder 47 for receiving the safety lamp 1 is welded to this plate. In the same way as before, the cylinder 47 is provided with a set screw 49 having a hexagonal hole to prevent the safety light from coming off. A semi-circular blind plate 50 is pivotally supported on the plate 46 so as to hide the screw so as to be openable and closable, and is tightened with bolts 43 and nuts 45. To prevent theft, after mounting, the screw thread at the tip of the bolt 43 is crushed so that the nut 45 does not come off.

[0015]

[Effect of device]

 In the safety light fixture according to claim 1, the tubular body is fixed to the clamp, the handle portion of the mushroom-shaped safety light is inserted into the tubular body, and the set screw with a socket is screwed into the screw hole formed in the tubular body. The safety light is tightened at the end of this screw. It cannot be removed without a wrench that fits the socket of the set screw, so it cannot be stolen easily.

According to a second aspect of the present invention, the clamp has a pair of jaws that are pivotally supported with respect to each other, a bolt that is pivotally supported at the tip of one jaw and that engages with a notch formed in the other jaw, and the bolt. It consists of a nut that can be screwed into the and can be easily attached to a fence or the like. Claim 3 has a set screw with a socket for preventing the rotation of the bolt, and claim 4 has a set screw with a socket for preventing the jaw from wide opening. However, it is unlikely that the safety lights will be stolen together with the fixtures.
