BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety light for traffic.

[0002]

2. Description of the Related Art As a conventional safety light, for example, a safety light for displaying the width of a road at night is a reflector plate type which receives and illuminates an illumination display section in front of the safety light base. , Or a lamp type that self-luminesces using a battery as a power source. In order to fix this to a cylindrical strut such as a guardrail, a screw hole is provided in the safety light, and both ends of the belt wound around the cylindrical strut are fixed by screwing the screw hole into the screw hole. A pair of left and right mounting protrusions having a rectangular cross section, which extend in the vertical direction and parallel to each other and which are arranged on the back surface, are inserted into the pair of mounting protrusions in a transverse direction in a state in which the support column is fitted. There is a type in which a tightening belt is inserted through the insertion hole for inserting the belt, and the belt is wound around the support and is fastened and fixed to the support. Therefore, a safety light of the type using a tightening belt is preferred and used because of its ease of fixing work.

[0003]

However, in the case of the type in which the safety light is fixed to the column by tightening with the tightening belt, the pair of left and right mounting protrusions having a rectangular cross section disposed on the back surface of the safety light is not provided. During tightening with the tightening belt, the horizontal movement of the column is merely controlled between the vertically opposed surfaces of these protrusions, and the force for pressing and pinching the column is not generated. Therefore, the safety light cannot be securely fixed to the column, and the security light often rotates during use,
This is a problem in that it deviates from a predetermined illumination direction and lacks reliability as a safety light.

[0004]

SUMMARY OF THE INVENTION The present invention solves the problem of such a type of safety light and provides a safety light that can be stably fixed to a cylindrical support by a tightening band. Is provided on the front surface of the, and the rear surface thereof is provided with mounting projections for a pair of left and right cylindrical columns extending in a vertical direction and parallel to each other, and at the bases of the pair of mounting projections, in a transverse direction. In a safety lamp having an insertion hole for inserting a penetrating tightening belt, the pair of left and right mounting projections are formed so that the facing surfaces are inclined surfaces that are closer to each other toward the lower end.

[0005]

Since the opposed inner surfaces of the pair of left and right mounting projections are formed as inclined surfaces, these opposed inclined surfaces exert a strong pressing and fixing action of holding the cylindrical projections against each other when tightened by the tightening band. Therefore, this prevents the safety light from rotating during use. Further, since they are the opposite inclined surfaces, they can be applied even if the diameters of the columns are slightly different, and the same clamping and fixing action as described above is performed.

In this case, by chamfering the outer edge of the belt insertion hole provided in each of the base portions of the pair of left and right mounting protrusions into an arcuate surface, the outer edge becomes a right angle when tightening the tightening belt. There is no concentration of tightening force on the tightening belt, which occurs in the case of the conventional safety light, and it is possible to prevent the belt from prematurely deteriorating at the portion that contacts the outer edge and extend the service life.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show an example of a safety light of the present invention. Reference numeral 1 denotes a casing-type safety light base made of synthetic resin having a circular peripheral surface, and inside the base 1, a storage battery such as a lead storage battery or a nickel-cadmium storage battery, a brightness / darkness detection device, a blinking circuit, a light emitting diode, etc. Is provided with a light-emitting illuminating device (not shown), the front surface of which is provided with an illuminating display portion 2 formed of a red or orange diffusion lens, and the solar cell 3, 3 is provided on the left and right on the upper surface of the circumferential wall. Is provided.

Thus, when the internal storage battery is charged by the solar cells 3 and 3 during the daytime and the night is detected by the brightness detection device, power is supplied from the storage battery to the light emitting diode through the blinking circuit to turn on the light emitting diode. The light is made to blink, and the light is diffused and emitted to the outside through the illumination display unit 2. For example, this is attached to a cylindrical column of a guard rail in a predetermined direction, and the illumination indicates the width of the road.

A pair of left and right protrusions 4 and 4 for attaching to the cylindrical column are provided on the rear surface of the base 1 so as to integrally project from the rear wall plate. The pair of left and right attachment projections 4 and 4 are provided by integral molding in the molding of the base body 1 and generally have a long length, and the rear surface thereof has an equal interval with respect to the center line. They are arranged vertically and parallel to the left and right. According to the present invention, the opposing surfaces of the pair of left and right protrusions 4 and 4 are formed on the inclined surfaces 4a and 4a that approach each other at the inner end, in other words, on the inclined surfaces 4a and 4a facing upward. And In the example shown,
The cross-sectional shape of each of the longitudinal projections 4 and 4 is formed in a substantially mountain shape or a substantially triangular shape as shown in FIG. Thus, the opposing inclined surfaces 4a, 4a are suitable for bearing contact with the circumferential surface of the column when the cylindrical columns such as guard rails are abutted between these protrusions 4, 4.

Furthermore, it is preferable that the tops of the pair of left and right protrusions 4 and 4 are formed on the rounded top surfaces 4b and 4b.
This softens the contact with the stanchion, prevents damage and provides a smooth guide into the groove-shaped space formed between the projections 4, 4.

Further, since the safety light of the present invention is of a type in which it is fixed to the column by tightening with a tightening band, a belt insertion penetrating in the width direction at the base of the pair of left and right protrusions 4 and 4 as in the conventional case. Although the holes 5 and 5 are provided, according to the present invention, it is preferable that the outer edge 5a of each of the insertion holes 5 has an arcuate surface. As a result, in the tightened state of the tightening band that occurs when the outer edge of the conventional belt insertion hole is at a right angle, the force does not concentrate at the position where the band hits the angular outer edge, and therefore at that portion. The tightening belt is prevented from being deteriorated at an early stage, the service life is increased, and a smooth and good tightening force can be maintained for a long period of time.

Although it is sufficient to provide one belt insertion hole 5 for each protrusion 4, a plurality of belt insertion holes 5 are provided at intervals in the lengthwise direction as shown in the figure, and three in the illustrated example. It is preferable that either one can be selected and used as desired.

FIGS. 4 and 5 show a state of use in which the safety lamp of the present invention constructed as described above is fixed to the cylindrical support by a tightening band. That is, as apparent from FIGS. 4 and 5, the cylindrical support 6 such as a guard rail is used.
, The inclined surfaces 3a of the pair of left and right protrusions 3 on the rear surface facing each other,
3a is applied, and a pair of left and right belt insertion holes 5 and 5 arranged on the pair of left and right protrusions 4 and 4 that are aligned in the width direction
The tightening belt 7 inserted in the above is wound around the outer peripheral surface of the support column 6 and fixed by tightening members at both ends of the band. Thus, due to this tightening force, the peripheral surface of the column 6 is crimped and sandwiched between the inclined surfaces 4a, 4a of the left and right protrusions 4, 4 facing each other. Thus, the force for sandwiching and fixing the strut 6 by the opposing inclined surfaces 4a, 4a increases as the tightening band 7 is tightened, and the securing light can be more firmly fixed to the strut 6. it can.

Further, since the facing surfaces of the pair of left and right projections 4 and 4 are formed as inclined surfaces 4a and 4a, the diameter of the cylindrical support column 6 to which the safety light is attached and fixed is, for example, as shown by an imaginary line. Even if they are different from each other, these pillars can be clamped and fixed, and like a conventional safety light, the fixed space formed between the vertically facing surfaces of the protrusions having a rectangular cross section protruding from the back surface is constant. In this case, one security light can be freely applied to columns having different diameters.

The indicator lamp of the present invention is of the type having a self-luminous illumination display section in the above-described embodiment, but instead of this, the base body is a plate body, It goes without saying that the surface may be modified to have a reflection plate type illumination display section for receiving and illuminating light.

[0016]

As described above, in the safety light of the present invention, the opposing surfaces of the pair of left and right projections provided on the back surface of the safety lamp are inclined upwards. When tightening on the pillar, the tightening force can clamp and fix the pillar between the opposing inclined surfaces of these projections, and therefore, the rotation during use such as the safety can be reliably prevented, and a safety lamp with improved reliability can be provided. Bring In addition, it has the effect of providing flexibility that can be applied to cylindrical columns having different diameters. Further, the outer edge of the tightening belt insertion hole is formed into an arcuate surface, so that the service life of the belt can be extended.
