Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an airport ground marking light system including a plurality of types of ground marking lights each having a different light distribution.

(Prior Art) A conventional terrestrial marker light installed at an airport is composed of a marker light body housing an optical system and a base for fixing the body to the ground. If these marker lights are classified according to their basic light distribution patterns, there are unidirectional types, bidirectional types, and all-round types. The marker light body and its mounting structure are different for each light distribution pattern. Furthermore, if classified according to the installation location, there are multiple types such as approach lights, terminal lights, runway edge lights, taxiway lights, etc. Each type has different desired projection angles and optical system characteristics, so the structure and specific light distribution are different. are different.

For this reason, in the past, marker lights suitable for each purpose were manufactured separately, which resulted in the following drawbacks.

Since a dedicated base is designed for each marker light body, many types of bases are required, which is disadvantageous in terms of manufacturing and maintenance.

When the marker light body is removed from the base, the light projection angle and the optical system related to the light distribution characteristics must be adjusted each time it is reattached at the site, resulting in poor work efficiency.

Flexibility was poor because it was not possible to attach different marker light bodies to a certain base.

Due to the above drawbacks, inspection and replacement work is troublesome and takes a long time.

Although it is not a beacon light for airports, it is
There was a marker light like the one shown in Publication No. 2274. Since this product does not require many types of indicator lights, the above problem does not occur in the first place, but if you try to create many types of indicator lights, the above problems and others will still occur. be. Furthermore, since this product does not pass the electric wire through the ball shaft (8 shown in Figure 1 of the same publication), the electric wire (14 shown in Figure 1 of the same publication) is outside the indicator light. The wire must be exposed, and there is a risk that the wire may break due to external force.

(Problems to be Solved by the Invention) The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and only requires preparing multiple types of marker lamp bodies each containing an optical system, and the base is common. To provide a terrestrial beacon light system for an airport that is inexpensive and easy to maintain by reducing costs related to design, manufacturing, inventory management, etc. for the base and other parts. With the goal.

[Structure of the Invention] (Means for Solving the Problems) The present invention comprises a common specification base fixed to the ground, and a common specification base fixed to the base so that the position can be adjusted. A support part, multiple types of marker light bodies that are detachably attached to the support part,
The marker lamp is configured to include an electric wire for supplying electric power to the marker lamp body, and a fixing means for fixing to the base.

The base has a cylindrical shape with a hollow part for passing electric wires that communicates from the lower part to the upper part, the lower part is directly or indirectly fixed to the ground, and the upper part has a recessed part along a substantially spherical surface.

The support part has a convex part on the lower part that engages with the recessed part in a position-adjustable manner, has a first hole for passing the electric wire at the substantially lowermost part, and has a holder on the upper periphery for attaching the indicator light main body. It has a seat.

The marker light main body has a second hole corresponding to the first hole in the substantially central part of the bottom surface, and a base body whose bottom periphery is removably attached in close contact with the receiving seat of the support section; It has a light projector mounted in close proximity to the light projector, and a light source housed in the space formed by the light projector and the base and powered by the electric wire, each of which has a and an optical system imparted with optical properties, and the bottom peripheral edge of the base body is removably attached to the receiving seat of the support part. Each of them houses an optical system provided with the required optical characteristics. As for optical characteristics, there are three types of basic light distribution characteristics: unidirectional, bidirectional, and all-round direction, but the specific light distribution characteristics, light output, light color, etc. differ depending on the type of marker light. It is allowed to do so.

The fixing means contributes to fixing the support part to the base after adjusting the projection angle by adjusting the relative position between the convex part and the concave part.

It should be noted that all types of the above-mentioned marker light bodies do not have to be used at the same airport; for example, the marker light of the present invention may be applied to ground-type marker lights within a certain area. Further, in the present invention, the shape and specific structure of the base and the support portion are arbitrary. Furthermore, the marker light main body can also have any structure including the structure for attaching it to the support part. What is required is that the base and the support have common specifications, and that the position between the base and the support can be adjusted to adjust the projection angle.

(Function) According to the present invention, the base is attached to the ground, and then the support section is attached to the base. Thereafter, the base of the marker lamp body, whose optical system has been adjusted in advance, is attached to the support. After installing in this way,
Position adjustment is performed to adjust the projection angle between the base and the support. Of course, the base of the marker light body may be attached to the support section in advance, and then the support section may be attached to the base. Note that the electric wire is connected to the light source from inside the marker lamp, that is, from the bottom of the base, through the first hole and the second hole. The means for connecting the electric wire to the light source is arbitrary.

According to the present invention, multiple types of terrestrial marker lights with different light distributions, light colors, light outputs, etc. are manufactured separately into the base, the support part, the marker light body, and the fixing means, and the base and the support part Since these are common specifications, a desired marker light can be easily constructed by combining desired parts. For example, runway lights that use bidirectional marker lights, approach centerline lights that use unidirectional marker lights, approach crossbar lights, approach row lights, terminal lights, terminal auxiliary lights, terminal lights, all-around lights. By appropriate combinations of taxiway lights and approach lights that use marker lights,
Can be provided.

In addition, the projection angle can be easily adjusted between the concave part of the base and the convex part of the support part, and if the optical adjustment of the indicator light body is done in advance at the factory, the projection angle can be easily adjusted at the site. It is easy to understand that all that is required is adjustment and attachment to the indicator light body and support. In addition, it is basically not necessary to adjust the projection angle when the marker light body is removed from the support and a new marker light body is installed, or when the marker light body is reinstalled after an inspection. Needless to say, there is no harm in implementing it.

Furthermore, the internal space of the marker light body communicates with the outside only through the first hole at the approximate center of the bottom surface of the base, while the support part communicates with the outside only through the second hole at the bottom. However, by closely attaching the peripheral edge of the base and the receiving seat of the support, measures such as waterproofing can be easily achieved. Furthermore, since the electric wire is routed from the bottom of the base of the marker light via the second hole, first hole, and hollow part inside the marker light, if the electric wire is routed underground, the marker light Signal lights can be turned on without exposing electric wires to the outside.

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

It is composed of 2.

To explain in detail the angle adjustment of the support part B with respect to the base A, first, a screw 20 is inserted from inside the support part B into the elongated hole 4 of the base A through the through hole 11, and this screw 20 is inserted into the long hole 4 of the base A. Adjust the angle by moving the washer 21 along the long hole 4 and set the washer 21 at the desired angle.
It is tightened with a wing nut 22 through the . In this embodiment, the screw 20 is attached to the inner surface of the support part B.
The screw 20 can be prevented from rotating by providing a frame portion 16 into which the head of the screw 20 fits. Note that the elongated hole 4 can be circular.

Next, each of the marker lamp bodies C1, C2, and C3 is removably attached to the receiving seat 15 of the support part B, and has a common attachment structure. First, the bidirectional marker light main body C1 will be explained with reference to FIG. 11. That is, in this embodiment, there is a base body 31 which has a second hole 30 in the center and is detachable from the support part B, and a bottomed base body 31 which is open at one end and which is attached in close contact with the base body 31. A light projecting section 32 made of a cylindrical cover, a light source 33 inserted through the second hole 30 of the base 31 and detachably attached from the opening side of the light projecting section 32 of the base 31, and this light source 33. two reflectors 34 such as ellipsoids of revolution or paraboloids of revolution that are provided opposite to each other and project light emitted from the light source 33; the base 31 and the light projector 32;
and a band-shaped fixture 35 for removably attaching. The attachment portion of the light source 34 is attached to the base body 3, for example.
This is a support plate 36 that straddles the second hole 30 of 1. In this embodiment, the reflector 34 is also fixed to the support plate 36. Then, the base 3

The configuration for attaching and detaching the marker light main body C1 and the support portion B will be explained. The claw 37 of the marker lamp main body C1 is engaged with the support shaft 13 of the support section B, and is supported rotatably around this engagement section. The screw 38
is attached to the notch 14 and the wing nut 40 is screwed together, thereby bringing the bottom periphery of the base body into close contact with the receiving seat. When removing it, the opposite is true. In this way, the marker light main body is removably mounted on the receiving seat 15. An optical system such as a light source 33 is mounted on the base body 31, and a light-transmitting portion 32 is attached thereto. Note that in this embodiment, a colored filter 41 can be provided on the light-transmitting portion of one of the reflectors 34.

The light source 33 can be easily replaced through the second hole 30 of the base body 31 by removing the marker light body C1 from the support portion.

Note that the electric wire is connected to the second hole 30, the first hole 12,
Since the wire is inserted through the hollow part 5 and connected to the light source 53 from the bottom of the base A, there is no problem in adjusting the projection angle within the range of wiring play, and the electric wire is connected from the marker light body to the bottom of the base. It is safe because the indicator light is not exposed to the outside.

Next, as shown in FIG. 7, the one-way type marker light main body C2 has a light projection opening 50 opened laterally in the upper part.
a base body 52 having a second hole 51 on the bottom surface; a light source 53 that is detachable from the second hole 51 of the base body 52; and a light source 53 that emits light from the light source 53 through the light projection opening 50. It has a reflector 54 that emits light, and a light projecting section 55 made of transparent glass and closely attached to the light projecting aperture 50. The light source 53

Therefore, similarly to the two-way marker light body C1, this marker light body C2 can also be attached and detached by using a wing nut 60 or the like to bring the bottom periphery of the base 52 into close contact with the common support portion B. Installed.
Note that a colored filter can be provided.

Since the all-round marker light body C3 differs from the two-way marker light body C1 only in the reflector 70, the same parts are given the same reference numerals and a description thereof will be omitted.

The present invention may include other different marker light bodies as long as they are unidirectional, bidirectional, or all-round. These different marking lamp bodies include, for example, those with different light colors and different light outputs depending on the light source, and in any case, those skilled in the art can form them according to the purpose, and if necessary, use lenses etc. may also be used.

Next, FIG. 12 shows an example of the layout of marker lights at an airport. D is the runway and E is the taxiway. F is a runway light, and a two-way marker light is used. G is the center line light, H is the approach center line light,
The approach crossbar light, I is the approach side row light, J is the end light, K is the end auxiliary light, and L is the end light, each of which is a unidirectional marker light and has a different light color, light distribution, etc. Also, M is a taxiway light, N is an approach light,
All-round marker lights are used. In the present invention, all of these marker lights have a common base and a support part, and also have a common mounting structure for each marker light body to the support part.

Note that the present invention is not limited to the above embodiments. For example, the shapes of the base and the support part are arbitrary. Further, the marker light main body can also have any structure including the structure for attaching it to the support part. What is required is that the mounting structure to the support portion be common to each marker light body.

[Effects of the Invention] As described in detail above, the present invention comprises a marker light separated into a plurality of types of marker light bodies, a base of common specifications, a support part, and a fixing means, and an upper part of the base. a concave portion is formed in the support portion, a convex portion that engages with the concave portion in a position-adjustable manner at the lower part of the support portion, and a receiving seat at the upper portion;
The light emitting angle of the marker light body can be adjusted between the base and the support part by forming the respective parts, and after the light emitting angle is adjusted, the support part is fixed to the base by the fixing means. , the following effects are achieved.
Since parts can be shared and costs related to design, manufacturing, and inventory management can be reduced, an airport terrestrial beacon light system can be provided at a low cost. The projection angle can be adjusted between the base and the support part, and the marker light body can be attached to and removed from the support part, so
When replacing a new marker light body with the same light distribution or reinstalling a marker light body that has been inspected, there is almost no need to adjust the projection angle again when installing the marker light body. Furthermore, since the optical system is housed within the marker lamp body, if the optical system is adjusted in advance at the factory, it is only necessary to attach the marker lamp body to the support portion at the site.

Therefore, work can be done easily and quickly, and maintenance management is easy.

Furthermore, the first hole and the second hole are holes that communicate between the inside of the marker lamp body or the inside of the base and the external space, but each hole can be connected by simply attaching the lower periphery of the base body closely to the receiving seat. can be isolated from the outside space and can prevent rainwater from entering.

Furthermore, since the electric wire is routed from the bottom of the base of the marker light via the second hole, first hole and hollow part inside the marker light, the projection angle can be adjusted within the range of wiring play. The electric wire can be routed from the marker light body to the bottom of the base without being exposed to the outside of the marker light without causing any hindrance. Therefore, for example, by wiring the electric wires underground, the marker light can be safely turned on without exposing the electric wires to the outside of the marker light.
