Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bonito-shaped marker light installed at airports and the like.

Generally, when installing this type of marker light, due to construction reasons, a recess is formed on the installation surface of the marker light, and
A base is buried in this recess, and then the marker light body is mounted on the base.

For this reason, when installing the Haru Shiji Light on the runway of an airport, there are construction errors when burying the base in the runway, and the runway itself has to be installed from the center to the south side due to drainage. ．．
Since the runway is designed to have a downward slope of approximately 5% and the vertical slope of the runway is also approximately 1%, the above-mentioned errors are corrected when installing the beacon light itself. Therefore, in the case of beacon lights that touch down on runways, the "U.S. Federal Aviation Administration (FAA) L-857
Adjustable bag hawks such as these were used to honor the main body of the beacon light as a base. This kind of adjustment device measures the difference between the maximum and minimum values of the difference between the runway surface and the top of the base, that is, the difference between the runway surface and the top of the base, at the runway construction site. The method of submitting an order by presenting relevant information to the manufacturer lengthens the period from ordering to delivery, that is, the delivery date, and also has the disadvantage that the adjustment device becomes expensive for the manufacturer as it is made to order.
As mentioned above, the information presented to the manufacturer is only about the slope, so there may be a difference in level between the runway surface and the marker lights, and the light distribution performance of the marker lights may be ignored. The marker lights were installed lower than the runway surface, and some of the light was cut off by the edges of the recesses, resulting in the amount of light emitted by the marker lights not reaching the required brightness. The present invention was made in view of the above points, and by combining a plurality of standard tapered annular plates so that their mutual positional relationship can be adjusted in the circumferential direction, an arbitrary oblique angle can be obtained. So,
This allows you to adjust the slope angle when installing the marker light body,
The aim is to achieve the required luminous intensity by aligning the indicator lights with the runway surface in the direction in which they are emitted, and also to solve the problem of delivery time and provide the product at a low cost. That is.

Next, one embodiment of the present invention will be described based on the drawings.

In Fig. 1, reference numeral 1 denotes an annular base frame, and a mounting plate 4 is attached to the lower surface of this base frame with screws 3 via a collar 2, and a lamp 5 is detachably attached to this mounting plate 4. A concave mirror 7 as a reflector is mounted operatively opposite the socket 6 and the lamp 5.

This upper surface cover i3 has a protrusion 15 in the center of the lower surface side, and the back of this protrusion is connected to the prism 1 and is connected to the light control body 9 as shown in FIG. A light guide port turtle 6 is formed to guide the light of the controlled lamp 5. In addition, 17 is a lower cover that houses the optical system unit 11 together with the upper cover wing 3 to form a marker lamp body 18. The lower surface cover 17 is formed in the shape of a cylindrical box and abuts the lower surface of the base frame 1 via a gasket 20 on the upper surface of an annular rim 19 formed at the entrance of the upper surface. Competitive green 2! is arranged around the outer periphery of the base frame and fixed to the bottom surface of base frame 1 with screws.

A bush 23 into which a conductive wire 22 connected to the lamp socket 6 is inserted is attached to the inner bottom of the lower cover 17. In addition, "the base frame 1, the prism IQ, the top cover 13
A marker light main body 18 consisting of a lower cover 17, etc.
The inside of is gasket 8, turtle 2, 28 and push 23
The airtightness is maintained. Further, 24 is an annular frame body, and a recess 25 is formed on the upper surface of the second base of this annular frame body, and the marker lamp body 18 is inserted into this recess 25 through a gasket 26. Combine the base frame 1,
Attach the upper magic bar 13 and the lower cover 17 with screws 2? It is fixed to the annular frame 24 at.

A light guide portion 28 facing the light guide port 16 of the top cover 13 is cut out in the upper surface of the annular frame 24 . Further, a plurality of, for example, four
This annular frame body 24 has a mounting hole 29 in the shape of an elongated circular arc hole, and the annular frame body 24 has a figure body 3 embedded and fixed in a recess 31 formed on the runway surface 3 as an installation surface as shown in FIG.
A mounting hole 29 is attached to the annular base 33 fixed near the closing part of the love.
It is fixed with a screw 34 inserted in the horizontal direction so that the horizontal direction can be adjusted. Furthermore, a pair of tapered annular plates 35936 constituting an adjustment device are inserted between the annular frame 2 supporting the wing fins of the marker lamp body and the base 33. As shown in FIGS. 4 and 5, these tapered annular plates 35 and 36 are arranged opposite to the through hole in the center of the base 33, and together with this through hole, the lower part of the marker lamp body 18 is It has a circular through hole 3 a, 362 to house it, and the cross section has a thickness a
It is formed in a tapered shape that changes linearly from the maximum part of wall thickness b and a' to the minimum part of wall thickness b and b', and four mounting holes 37 corresponding to the mounting holes 29 of the annular frame 24 are formed, and their respective tapers or obliques are represented by (a-b) outside diameter] and (a'-b') outside diameter 1. Then, when combining the pair of tapered annular plates 353 and 36 and installing them between the annular frame 2 and the base 33 using the three screws through the mounting holes 37, each tapered annular plate By changing the mutual positional relationship of the bodies 36, 36, (a0a'-bHb')/1
The annular frame 24 and the marker light main body 18 can be tilted in four stages with respect to the base 33 between the ``pair of combined tapered annular plates''. Depending on the mounting direction of the bodies 35 and 36, the head diagonal directions of the annular frame 24 and the marker light body 18 can be set in four directions.Thereby, when installing the marker light body turtle 8 on the runway,
As shown in FIGS. 1 and 3, even if the runway surface 30 and the upper surface of the base 33 are not parallel, the outer edge A of the annular frame body 24 on the light guide portion 28 side and the recess 3 formed on the runway The height of the edge B of the marker light can be made to match the height of the marker light body 8, so that a part of the light emitted from the light guide port 6 of the marker light body 8 is cut off by the edge B, resulting in insufficient light emitted from the marker light. In this way, when installing recessed marker lights on a runway, if the top surface of the base 33 is obliquely inclined relative to the runway surface 301 as shown in FIG. ~ Conventionally, the maximum value h of the difference between the runway surface 30 and the top surface of the base 33, and the maximum value h of the difference between the runway surface 30 and the top surface of the base 33,
・In contrast to measuring values such as h2 after the runway construction and ordering adjustment equipment, it is now possible to install recessed marker lights on-site using a pair of standardized and manufactured tapered annular plates 35 and 36. Can be installed properly.

In addition, in this embodiment, each tapered annular plate body 36, 3
The mounting holes 37 of No. 6 are provided at four locations corresponding to the mounting holes 29 of the annular frame 24, but the invention is not limited thereto. In addition, the forehead oblique direction may be set in eight directions, and each mounting hole 37 may be formed into an arcuate long hole shape so that the inclination angle and the oblique direction can be finely adjusted. Furthermore, the number of tapered annular plates may be three or more.

Further, although this embodiment has been described with respect to a recessed marker light installed on a runway, the present invention is not limited to this, and may be applied to an embedded marker light installed in other locations, such as a ceiling surface or a wall surface.

In addition, when the light emitting direction of a recessed marker light is not only in one direction but in multiple directions, multiple tapered annular plates can be used to adjust only the inclination angle and diagonal direction of the marker light. Appropriate light distribution and amount of light can be obtained by adjusting the unevenness using a plate member such as a smoother ring having a uniform wall thickness.

According to the present invention, by combining a plurality of tapered annular plates with mutual alignment pupils shifted in the circumferential direction, any oblique angle can be obtained, so that the recessed indicator light can be properly adjusted on-site. It can be installed at
When installing marker lights at airport runways, etc., ``a large number of marker lights can be installed easily and inexpensively.

Further, since a part of the marker light main body can be accommodated in the through hole of the tapered annular plate, there is no need to make the recess into which the marker light is embedded particularly large.
