Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recessed marker light that is buried in the road surface of an airport, a road, or the like.

For example, recessed marker lights that are buried in road surfaces such as airport runways and VJ4 roads are formed of a base and a light body supported by this base. The floodlight window is exposed and buried above the road surface so that a beam of light is emitted from the floodlight window.

There is also an I-wire wire that connects to the lamp rung buried underground.

By the way, road surfaces such as airport runways have been uneven for many years and the ground has subsided, so there are cases where the road surface is uneven. Then, the marker light C was buried before the elevation was raised.
The height of the increased height makes the legs less comfortable. For this reason, conventionally, the marker lights that were buried before raising the height are left buried, and new marker lights are installed after the raise. However, if the marker lights that were buried before the elevation are left buried, the marker lights cannot be used and new wiring work must be performed, which is inconvenient, such as being uneconomical.

Therefore, when carrying out the raising work, the light body is removed, the base buried in the road surface 42 is covered with a lid body, and the raising work φ is carried out. Then, after the construction is completed, a hole is made at the base burial point (one hole is made and a joint frame corresponding to the thickness of the raised part is inserted between the base and the light body to maintain the height). Please make use of the marker light in front of you.

However, the design of the conventional tread joint frame is that it has an inner cone so that its height matches the height of the height.
After the road surface is raised, measure the height and make a fence, or measure the height by stacking thin boards (T-1) or square boards on a joint frame that maintains the approximate height. I'm making adjustments. Therefore, in the former case, the joint frame is manufactured after raising the road surface level, which leads to a long construction period and makes it difficult to adjust the height due to design errors. Since a plurality of plates must be prepared, the number of parts increases, management of the parts becomes troublesome, and there are disadvantages such as insufficient airtightness between the plates 9 and poor corrosion resistance.

The present invention was made in consideration of the above-mentioned circumstances, and it is an object of the present invention to provide a built-in marker light whose height can be easily adjusted according to the height of the road surface and which can maintain sufficient airtightness. shall be.

The non-inventive feature is that between the base and the lamp body (1 the inner circumferential surface (2) an annular first frame member formed with two threaded portions, and the outer circumferential surface of the above-mentioned threaded portion (2);
The present invention is characterized in that an adjustment frame is interposed which includes a second frame member whose threaded portion is adjustable by an M-screwed screw.

The details of the present invention will be explained below with reference to the illustrated embodiments.

Reference numeral 2 denotes a base, and this base 1 is formed into a cylindrical shape with a bottom and a double opening 2 at the top, and is buried in the road surface.

The base 1 has four mounting holes (not shown) formed in the opening edge 3 at approximately 90 degree intervals. 4 is a joint frame,
The height of this joint frame 4 has been significantly reduced due to the elevation of the road surface. An aluminum or iron cast product having four screw holes 5 provided at approximately 90 degree intervals along the circumferential direction and four through holes 6 provided between these screw holes 5. This joint frame 4 is attached to the 4 mortar 1 by screwing a bolt (not shown) into the hole 6t-.7 is a device attached to the top surface of the joint frame 4. Adjustment frame C1 This adjustment frame 7 includes a first frame member 9 which is annular and has a threaded portion 8 formed on its inner circumferential surface, and a second frame member 9 which is annular and has a screw $10 that is screwed into the threaded portion 8 in the outer circumferential direction. frame member-
11, and the screwing amount of the second frame member 11 is adjustable.
In the non-embodiment, the first frame member 9 includes a peripheral wall 12, an annular protrusion 413 protruding inward from the lower surface of the peripheral wall 12, a threaded portion 8 formed on the inner peripheral surface of the peripheral wall 12, and the protruding wall 13. (
2. The screw hole 5 (=corresponding mounting hole 14) of the above-mentioned joint frame 4 is formed, and the second frame member 11 is an annular plate-shaped body, and the screw hole of the first frame member 9 is formed on the outer peripheral surface. The threaded part 10 screwed into the part 8 is M, and is formed with threaded holes 15 provided at approximately 90 degree intervals on the plate surface. Screw the second frame member 11 into the
The height can be adjusted by the amount of screwing in, and after adjustment, the tip of the screw 16 screwed in from the inner circumferential surface of the second frame member 11 is joined to the inner circumferential surface of the first frame member 9, and the first and A second frame member 9.11 is fixed. Reference numeral 17 denotes a lamp body, which houses an optical system 18 therein, has a light projection window 19 on its upper surface for guiding light from the optical system 18, and is mounted on a holding frame. The lamp body 17 has a disc shape, for example, and has a light projection window 19 that opens laterally on the upper surface, and has bolts 27 (installed in a two-piece unit) on the support surface 21 of the holding frame 20.An optical system 18 is formed so that the light from the lamp 22 is irradiated from the light projection window 19, and includes the lamp 22, a reflector n provided opposite to the lamp 22, and a lens 24t provided opposite to the light projection window 19. A screw insertion hole is formed in the holding frame portion 20 of the lamp body 17, and the screw insertion hole is inserted into the second frame member 1 of the adjustment frame 7.
It is fixed by a bolt b screwed into the screw hole 15 of No. 1. A is a bolt that fixes the first frame member 9 to the joint frame 4.

Next, the effect will be explained. After raising the road surface, in order to support the light body 17 on the base 1 buried in the road surface, first, if necessary depending on the height of raising the surface g, move the joint frame 4 to the base l.
l: Maintain the device at the approximate height.

At that time, the joint frame 4 is the through hole 6? :The mounting provided on the through base l is fixed to the base l by a bolt screwed into the hole. Next (2) install the first frame member 11 of the adjustment frame 7 to the joint frame 4. At that time, the first frame member 11 is installed by aligning the holes 14 with the screw holes 5 of the joint frame 4, and using the bolts 26 The first frame member 9 is fixed to the joint frame 4 by screwing the second frame member 11 into the threaded portion 10i of the first frame member [1], and the height is determined by the screwing amount. Once the adjustment is complete, screw in the screw 16 and connect the tip to the inner circumferential surface of the first frame member 9 and fix it. 11, and then screw the bolt 6 into the screw hole 15 through the through hole (- υ, so that the lamp body 17 is fixed at the required height. Therefore, raise the height. The adjustment distortion frame 7 absorbs the height mllffi error and the design error due to this, so that the lamp body 17 can be maintained at the required height.

Further, since the adjustment frame 7 is adjusted by the amount of screwing, airtightness is maintained and corrosion resistance does not deteriorate.

Although the invention has been described with reference to the illustrated embodiments described above, the invention may include various embodiments. As described in detail above, the present invention includes a first annular frame member formed with a thread on the inner circumferential surface between the base 2 and the lamp body, and the above-mentioned threaded part (two threaded parts) on the outer circumferential part. Since an adjustment frame including a second frame member whose height is adjustable depending on the amount of screwing is inserted, it is possible to adjust the taste and maintain sufficient airtightness. ■Since the straight frame can be formed by a pair of annular bodies, it is possible to make a four-structure structure with a single unit, and it is also inexpensive because the number of parts is small.
