In addition, the above-ground type marker light installation device has a structure in which the light body 2 is attached to the side of the mount 1 using the conventional joint 3. Although the amount of protrusion of the marker light above the ground can be reduced, the installation requires many parts and is difficult to install. There was a problem with the construction.

The above-mentioned conventional above-mentioned above-mentioned equipment for installing above-ground marker lights has the problem of requiring wiring within the pavement, making installation difficult and expensive.

The present invention was made in view of the above problems, and it is possible to reduce the height of the marker light by reducing the amount of protrusion from the ground surface, and also to provide bendability, improve safety, and connect power cables. The present invention provides a device for installing ground-type marker lights that is easy to install and has improved installation workability.

[Structure of the Invention] (Means for Solving the Problems) The terrestrial marker light installation device of the present invention includes a pedestal and a light body attached to the upper part of the pedestal, and the pedestal has an opening on its outer circumferential surface. and an electric wire outlet and an electrical connection contact disposed on the top surface, and the lamp body has a mounting portion formed therein;
The lamp body includes a light control cover, an optical system disposed within the light control cover, and is electrically connected to the optical system and connected to an electrical connection contact of the mount when it is attached to the mount. an electrical connection contact, and the pedestal is attached to the part and the object to be attached forms a part; The device is characterized in that the fastening is performed using a screw member having a portion formed therein.

(Function) The above-ground type marker light installation device of the present invention mounts the light body directly on the pedestal, so the amount of protrusion of the light body to the ground surface can be reduced. The electrical connection contacts and the electrical connection contacts of the lamp body are in contact, and the electric wires connected to the electrical connection contacts of the mount do not need to be routed into the pavement through the wire outlet opened on the outer circumferential surface of the mount. Wiring can be done on the surface, installation is easy, and when an aircraft or the like comes into contact with the light body, the screw member that attaches the light body to the mount will break at the bendable constriction, and there will be no damage to the aircraft. This can improve safety.

(Example) The configuration of an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 10 denotes a pedestal, and the pedestal 10 has a light body 11 attached to the top thereof.

The pedestal 10 has an electric wire outlet 12 opened on its outer peripheral surface, and a pair of electrical connection contacts 14 arranged on its upper surface surrounded by an annular wall 13. The electrical connection contact 14 is connected to a power supply connection wire pulled out from the wire outlet 12, and this electric wire is inserted into a conduit placed on the paved surface outside the wire outlet 12 and wired. . Further, on the outer circumferential surface of the pedestal 10, two fixing attachment portions 15 are integrally protruded on both sides along the running direction of the runway, for attaching the pedestal 10 to the paved surface with anchor bolts. This fixing attachment portion 15 is formed with an anchor bolt insertion portion 16 that is open upwardly and downwardly and outwardly. Further, on the outer circumferential surface of this pedestal 10, there are mounting portions 17 for light bodies on both sides in the direction perpendicular to the running direction of the runway.
are prominently displayed. A screw hole 18 penetrating vertically is formed in the lamp mounting portion 17.

Reference numeral 20 denotes a lamp body, and on the outer circumferential surface of both sides of the lamp body 20, the lamp body mounting part 17 faces the part 17, and the part 2! is integrally formed in a protruding manner, and the mounting portion 21 has a screw or insertion hole 22 that is open upwardly and downwardly and outwardly.

Further, an annular fitting groove 23 is formed on the upper surface of the lamp body 20, and a light control cover 25 such as a glove is fitted into this fitting groove 23 via a backing 24. Furthermore, a board 26 is attached to the lamp body 20. This board 2
A lamp socket 27 is attached to the upper surface of the lamp 6, and a lamp 28 constituting the optical system is mounted in the lamp socket 27.
is detachably attached, and this lamp 28 is disposed within the light control cover 25. Further, a pair of electrical connections protrudes from the lower surface of the substrate 26 and is electrically connected to the lamp socket 27, and is brought into contact with the electrical connection contacts 14 of the pedestal 10 when the lamp body 20 is attached to the pedestal 10. A contact 29 is attached.

Further, 30 is a threaded member such as a screw or bolt made of aluminum, plastic, etc., and a bendable constricted portion 31 is formed in the middle of this threaded member 30. Then, the light body 20 is placed on the pedestal 10, and the pedestal 10 is placed on the pedestal 10.
To attach the lamp body 20, attach the part 17 to the part 17, and attach the screw member 30, which has a bendable constricted part 31 in the middle, from the insertion hole 22 of the part 17 to the mounting frame 10. It is adapted to be screwed into a screw hole 18 formed in the portion 17.

Next, the operation of this embodiment will be explained.

The frame 10 is fixed to the paved surface of the edge of a runway or the like using anchor bolts inserted into the anchor bolt insertion portions 16 of the section 15. The electrical connection contact 14 of this pedestal 10 is connected to the power supply connection wire drawn out from the wire outlet 12 . This electric wire is inserted into an electric conduit placed on the paved surface outside the electric wire outlet 12 and wired.

The light body 20 is placed on the upper part of the pedestal 10, and the mounting part 17 of the pedestal 10 is aligned with the part 17 to which the light body 20 is attached. The screw member 30 having the fin part 31 is attached to the pedestal 10 at the part 17.
