Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applied to an automatic machine, a robot, a production line, a parking lot,
The present invention relates to a signal indicator lamp which is installed in a dangerous place or the like and is used for signal notification of various states such as lack of material, jammed work, full vehicle, and danger.

<Prior Art> This type of indicator lamp gives a signal notification by irradiating the surrounding area with light of one or a plurality of colors, thereby alerting or guiding the user such as a worker, and thus the user. It is installed in order to maintain the safety of the machine and maintain it for automatic machines and equipment.

In the related art, the indicator lamp has conventionally formed an independent display structure for each emission color and stacked them in multiple stages. For example, as shown in FIG. 9, the signal indicator lamp has a plurality of socket plates 32 accommodating the respective light sources 33 stacked on each other via a shaft 31, and each step is colored and has a substantially cylindrical colored transparent shape. It is covered with a light-glove 34. With the glove 34,
The light from the light source 33 can be colored and diffused and emitted laterally to improve the visibility of the indicator lamp itself.

As described above, in the conventional indicator light, since the globes 34 are laminated in a plurality of stages according to the number of colors, the structure becomes vertically long, compact, and the height of the installation place is restricted. In particular, the larger the number of colors, the longer the size, which is a disadvantage for the installation conditions.

In addition, in the structure of the conventional signal indicator lamp of FIG.
Since you will be mounting the signal indicator using, you can fix it on a flat surface or mount it on a wall using a bracket, but for example, hook it on a hook or attach it to the end of the wall I couldn't.

Moreover, since the number of stages must be changed to change the number of colors, the structure of the signal indicator lamp changes, and the shaft 31 must be replaced.

An object of the present invention is to provide a signal indicator lamp which can be compactly constructed regardless of the number of colors, does not change its overall shape even if the number of colors changes, and has a large degree of freedom in mounting. .

<Means and Actions for Solving the Problem> A signal indicator lamp of the present invention for achieving the above-mentioned object is a cylindrical casing and a cylindrical casing for emitting light from one opening end of the cylindrical casing. A signal indicator light having a plurality of lamps mounted on an internal chassis and a globe covering the opening end, wherein the tubular housing has a side surface of the housing having an elongated cut along the direction of the cylinder axis, and the cut. At the same time, the joint portion that forms the connecting groove portion is integrally formed.

As described above, since the tubular housing has the housing side surface and the joint portion integrally formed, it can be cut to a desired length, and the length is the number of lamps mounted on the internal chassis. It doesn't depend on.

Also, since it can be attached using the connecting groove of the joint,
The degree of freedom of installation increases.

The joint part is cut off obliquely toward the center part of the cylinder at the opening end of the cylindrical housing, and the plurality of lamps are from the filament of any one lamp to the opening end of the cylindrical housing. It may be arranged at a position where it is not blocked by any other lamp or joint portion.

According to this structure, compared to a structure in which multiple colored lamps are prepared and covered in a single globe, even if one lamp is lit, the other unlit lamp radiates Since it does not block light, the shadow of other lamps and joints is not reflected on the globe.

<Embodiment> An embodiment will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a signal indicator lamp, and the signal indicator lamp is
A tubular casing 1, two lamps 6a and 6b mounted on an internal chassis 7 of the tubular casing 1 for emitting light from an open end 9 of the tubular casing 1, and a milky white hemispherical globe covering the open end 9
Have 10 and.

The tubular casing 1 is formed by extruding a casing side face 2 having an elongated notch 3 along the direction of the cylinder axis and a joint part 4 for joining the casing side faces 2 on both sides of the notch 3 from inside the casing 1 by extrusion molding or the like. It is obtained by cutting the product formed into a desired length.

The joint part 4 is cut off obliquely toward the center part of the cylinder at the open end 9 of the cylindrical housing 1 (the cut surface is indicated by 5) so as not to block the light of the lamps 6a, 6b. Has been done.

8 is for fixing the hemispherical globe 10, so the hemispherical globe 10
It is an insertion hole into which a protrusion (not shown) is inserted. Reference numeral 20 denotes a power cord, which can be put in and taken out from the notch 3 as shown in FIG. 1, which is advantageous when the bottom of the tubular housing 1 is directly attached to the installation surface.

FIG. 2 is a transverse sectional view of the signal indicator lamp, and FIG. 3 is a side sectional view of the signal indicator lamp. The joint portion 4 with the opening side cut off.
One end of the metal fitting 11 is hooked on the metal fitting 11, and the square internal chassis 7 is fixed to the other end of the metal fitting 11. Lamp sockets 12a and 12b are attached to the diagonal positions of the internal chassis 7, and the lamps 6a and 6b are detachably attached.

The above two lamps 6a and 6b are lamps as shown in FIG.
From the filament 61a of 6a to the opening end 9 end, it is arranged at a position where it is not blocked by the globe 62b of the other lamp 66b or the notch 3 of the joint portion 4, and from the filament 61b of the lamp 6b to the opening end 9 end. The lamp 62a is arranged at a position where it is not blocked by the globe 62a of the other lamp 66a or the notch 5 of the joint portion 4.

With the above-described configuration, even if either of the lamps 6a and 6b is turned on, the shadows of the globes 62a and 62b of the other lamps and the joint portion 4 are not reflected on the hemispherical globe 10. In addition, by using a milky white object on which the light of the lamp is projected uniformly and softly on the hemispherical globe 10, the appearance design becomes excellent.

If the lamps 6a and 6b are color lamps and are mixed and turned on, an arbitrary display color can be obtained. For example, simultaneous lighting of the red and yellow lamps results in orange, and simultaneous lighting of the red and blue lamps results in magenta.

Further, when fixing the tubular housing 1 to the installation location, the tubular housing 1 is installed by using the notch 3 of the tubular housing 1 and the connecting groove portion 41 of the joint portion 4. That is, as shown in FIG. 6, an elongated plate 14 having holes is prepared and fitted in the connecting groove portion 41 in the vertical direction (see FIG. 7). Then, the signal indicator lamp is fixed by hooking it on the outer hook 15 (see FIG. 6). Further, instead of the single hook 15, a plurality of hooks can be hooked on a flat plate having an end surface. It is also possible to construct a large machine housing with this flat plate.

The plate 14 may have a convex cross section, as shown in FIG. In this case, the notch 3 is closed when it is inserted into the cylindrical housing 1, which is good in appearance.

Further, since the tubular housing 1 can be cut into a desired length, for example, if it is cut into a short length, it becomes compact and can be easily installed in a low place.

In the above embodiment, the light of the lamp may leak out through the elongated cut 3 provided on the side surface 2 of the housing.
To prevent this, as shown in FIG.
May be attached to the cut surface 5 of the joint portion 4.

Although the invention has been described in detail with reference to the accompanying drawings, the invention is not limited to the above specific embodiments. For example, although the number of lamps is two in the above embodiment, the number of lamps is not limited to two, and any number of lamps can be mounted as long as the shadow of the lamp does not occur. This way you can get different kinds of light colors. Moreover, unlike the conventional example (see FIG. 9), the length of the tubular casing 1 does not depend on the number of lamps mounted on the internal chassis 7, so the tubular casing 1 is cut into short pieces. If you do so, you can choose the installation conditions. Besides, various modifications can be made without departing from the scope of the invention.

<Effect of the Invention> Since the signal indicator lamp is configured as described above, the length and shape of the signal indicator lamp do not change regardless of the number of colors, so that the installation location can be easily selected.

In addition, it can be attached in various ways such as hooked on a hook or attached to an end surface of a wall.

Moreover, since the shadows of other lamps can be prevented from appearing on the globe, the globe can be uniformly illuminated and various signal notifications can be reliably performed.
