Description

[Detailed description of the invention] The present invention relates to a barricade used for safety at civil engineering and construction sites, and particularly relates to a barricade equipped with a warning light so that a clear warning can be given even at night. .

At construction sites such as civil engineering and construction, it is common practice to notify workers there, other passersby, passing vehicles, etc. of dangerous areas, and to use barricades to prevent them from entering the areas. In addition, other terms such as fence or protective fence are also generally used, but in this specification, these are also included in the term barricade.
By the way, barricades must perform their functions day and night, so red warning lights are also used to improve visibility, especially at night.
However, according to the conventional method of installing this type of barricade, the barricade and the warning light are completely separate bodies, and after the barricade is installed, the warning light is hung separately from it, and the power supply to the warning light is also required. The wiring was extended so that it was wrapped around the barricade. However, when using this method, it has been said that the red warning light is not secured sufficiently, causing it to shake and fall in strong winds, or that the cord becomes entangled with the barricade itself, making it difficult to handle. Various problems arose. Moreover, each time the work site is moved, the barricade and the warning light containing the cord must be stored and transported separately. Damage was inevitable. By the way, some relatively large-scale road signs and construction signs contain light bulbs and other objects to give them a light-emitting function, but such signs rarely move, and even if they do, they do not move at all. Since barricades are transported by special vehicles, the problems described above with relatively simple barricades do not occur as much. Furthermore, if the light emitting body is simply attached to the barricade as one piece, it is somewhat easier to handle, but the problem of the light emitting body being easily broken each time the barricade is stored or transported remains unsolved.

The present invention was developed in view of the current situation, and is mainly aimed at relatively simple barricades.A warning light is attached to the barricade body so that it can be protruded and retracted, and the warning light can be retracted when not in use. By doing so, it is possible to prevent damage to the part of the warning light that is most likely to be damaged, and to obtain a barricade that is easy to handle.

The present invention will be explained in detail below based on the illustrated embodiments. FIG. 1 shows a state in which barricades 1 according to the present invention are used, and a large number of barricades 1 are installed at appropriate intervals in a place where construction work is being carried out. The specific structure of the barricade body 4 is a combination of a front leg part 2 and a rear leg part 3.
However, as an example, a warning light 6 is attached to the upper frame 5. Of course, it is provided on the upper surface of the upper frame, but it may also be provided on the front surface of the upper frame, or on the legs of the barricade body or any other suitable location. This warning light is configured to be able to protrude from and be retracted from the barricade body, and has the following configuration as an example. That is, as shown in an enlarged view in FIG.
is provided to support the base of the lid plate 11 there.

And this rotation fulcrum 10 has a lifting spring 1.
2 is wound, and the active end of the spring is locked near the base of the cover plate 11, so that the cover plate 11 always has a tendency to protrude. A light bulb 13, which is the main body of the warning light, is attached to the cover plate 11, and a reflector 14 is provided as necessary so that the light source spreads in an appropriate direction. Of course, when such a reflector 14 is not needed, it is not necessary to attach it. Lenses 15 of red color or the like are provided in front and on the sides so as to surround this light bulb. Furthermore, this upper frame 5 is provided with a slidable opening/closing catch 16, and correspondingly, the lid plate 11 is provided with an opening/closing catch 16.
A receiving portion 17 is provided. Furthermore, the reference numeral 18 is a micro switch for detecting the opening/closing state of the cover plate 11, and is configured to close the power supply circuit to the warning light 6 when the cover plate 11 is opened. Next, a power supply circuit to this warning light 6 will be explained. Of course, this power supply circuit itself is already a well-known method, and only one barricade that draws in power is equipped with a transformer T and a photosensitive element that detects the brightness of the surroundings and automatically lights up when it gets dark. A so-called pulsar unit _P0 , which is mainly made of bimetal and supplies power intermittently, is installed. Of course, such a transformer T and pulser unit P ₀ are appropriately housed in the barricade body 4, but these are not required for the second and subsequent barricades.

A pair of left and right connection cords are then attached along the support legs of the barricade body 4. That is, one cord 20 has a socket 21 attached to its tip, and the other cord 22 has a plug 23 attached to its tip. This allows continuous barricade connection. Of course, this situation is a configuration in which a 100-volt power source is used from a nearby utility pole at a construction site, etc., but in consideration of cases where such a power source is not available, each barricade 1 is equipped with a battery of about 3 volts. Incorporate a circuit that will work. That is, a circuit configuration is constructed in which a battery is housed as shown by reference numeral E in FIG. 6, a pulser unit _P1 is similarly interposed therein, and power is supplied to the light bulb via the microswitch. Of course, such a power battery is only used when 100 volt power is not available or in an emergency such as a power outage, so it is best to use 100 volt power at all times.
If this is not possible, a switching circuit C is automatically activated to switch to operation using the power source battery.

Since the present invention has the above-mentioned configuration, when it is used, the barricades are arranged at appropriate intervals and the sockets 21 and plugs 23 of the cords 20, 22 of each barricade are connected, and the tip of the barricade is connected to the nearby barricade. The 100 volt power source is taken in from utility poles, etc. At such times, the pulsar unit _P0 is activated by detecting the brightness of the surrounding area and stands by in a power supply state. Then, when the operator pulls the opening/closing catch 16, the opening/closing catch 16 and the cover plate 1
1 is disengaged, the cover plate 11 is lifted upward by the action of the lifting spring 12, and the warning light comes to protrude from the upper surface of the barricade body 4. At that time, the micro switch 18 also closes its circuit and supplies power to the light bulb 13 to turn it on, and the light bulb 13 lights up intermittently by the action of the pulser unit _P0 . On the other hand, if a 100 volt power source is not available, the DC power from the power source E is supplied to the pulser unit _P1 , which is further supplied to the light bulb 13 via the micro switch 18 to turn it on. And when not in use, the opening/closing catch 16
By pulling the button and pushing the cover plate 11 away, the warning light 6 is stored inside the barricade body 4. and code 20 for each barricade 1,
By separating the socket 21 and plug 23 at 22, the barricade can be transported and moved in a folded state. In such a state, there is no risk of damage to the warning light during transportation or movement since it is not exposed at all.

As described above, according to the present invention, the warning light is integrally installed within the barricade body, and the warning light itself is configured to be stored within the barricade body, so it can be used by protruding only when in use. It is extremely convenient to handle, as it does not require a long power cord.
