Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention has a grip portion and a light emitting portion extending from the grip portion. The present invention relates to a rod-shaped signal light that gives a signal to.

[Prior Art and Its Deficiencies] In the past, the rod-shaped signal light illuminates a transparent colored hood such as red, which is a light emitting part, from a miniature light bulb with a base provided in the grip, and the light emitting part emits light to the outside. Since the light source emits a small amount of light, and the light emitted from the light emitting portion is indirect light and is attenuated when the light passes through the hood, the visibility is poor and the effective light reaching distance is small. Therefore, recently, a large number of light emitting diodes (LEDs) have been installed in the transparent colored hood, which is a supporting member in which a large number of miniature bulbs with bases or non-baseless miniature bulbs are mounted in the transparent colored hood that is the light emitting part. An extension of the support member has come into use.

And improvement of the attachment of the above-mentioned luminous body to the support member,
In order to reduce the manufacturing cost of the illuminating body and avoid the difficulty of the irradiation directivity of the illuminating body, an illuminating body configured by connecting an omnidirectional light emitting bulb in parallel between two parallel conducting wires is provided. A light-emitting part signaling lamp that is inserted into a transparent synthetic resin hood and has a colored transparent sheet on the inner circumference of the hood is

However, in this rod-shaped signal light, the diffusion of light from the light bulb is not good, so when the signal light in the lit state is viewed from a distance, it emits dots from the same number of light emission points as the number of light bulbs. However, there is a problem that the visual recognition performance is low. In order to improve this, it is necessary to shorten the interval between the light bulbs, so there is a problem that an increase in the number of light bulbs leads to higher cost and higher power consumption. In addition, since the bulb is connected in parallel between the pair of conducting wires, the stability of the support of the bulb and the conducting wire is low, and there is a problem that electrical contact failure, failure such as disconnection is likely to occur during use of the rod-shaped signaling light. is there. Furthermore, since a synthetic resin hood having a relatively thin and uniform thickness is used as a whole, it has poor impact resistance, and there is a problem that end portions are likely to be damaged when dropped or hit by another object. .

In order to improve the visibility from a distance and to improve the stability of the support of the conductor and the bulb, connect the bulb to the conductor by alternately projecting the bulb on both sides of the printed wiring board. A rod-shaped signal light in which a reflecting plate having a corrugated inner surface is attached and a part of the light bulb is exposed to the outside through holes formed at intervals in the longitudinal direction of the reflecting plate is disclosed in Japanese Utility Model Laid-Open No. 63-20299. The specification and drawings of Japanese Utility Model Application No. 61-112142).

However, in the case of this rod-shaped signal light, the light bulbs are arranged so that they alternately project on the front and back of the printed wiring board, are connected by conducting wires, and each light bulb is fitted into the holes in the front and back reflection plates. Therefore, a printed wiring board for supporting the light bulb and the conducting wire and front and back reflectors for light diffusion are required, and holes for mounting and exposing the light bulb are required. There is a problem that cost and processing cost increase the product price.

Further, since the reflector and a part of the light bulb are exposed to the outside, they may be damaged during use of the signal light. further,
Since there is little light irradiation in the direction parallel to the reflector, there is a problem in that the visibility is poor depending on the direction.

[Technical problem to be solved by the invention] In this invention, an illuminating body in which a light bulb is connected in parallel between two parallel conductive wires is inserted into a transparent synthetic resin hood, and a colored transparent sheet is placed in the hood. In a rod-shaped signal light having a structure, the support stability of a light bulb and a conductor is improved, and the diffusion of light emitted from each light bulb is improved by a simple structure.
Moreover, it is an object of the present invention to provide a rod-shaped signal light in which the light-emitting portion becomes a rod-shaped light-emitting body that irradiates in all directions even if a small number of light bulbs are used, and visibility from a distance is improved.

Another object of the present invention is to prevent damage to the end portion due to an impact that may be applied during use when using a single synthetic resin cylinder in order to reduce the manufacturing cost of the rod-shaped signal light. .

[Means for Solving the Problems] In order to solve the above-mentioned problems, the rod-shaped signal light according to claim 1 according to the present invention has a grip portion and a light emitting portion, and the grip portion is formed in a hollow shape, and is internally formed. The blinking circuit is provided, and the light emitting portion is provided in the tubular transparent hood that is connected to one end of the gripping portion, and is provided in the hood and has a length substantially equal to that of the hood, and one end of the blinking circuit is connected to the blinking circuit. In a signal light including a connected lighting body, the lighting body includes a strip-shaped support member made of a transparent synthetic resin in which conductive wires are embedded at both ends in the width direction, and holes provided at positions separated in the longitudinal direction of the support member. The omnidirectional light-emitting bulb that is accommodated so that the emitted light enters the support member and is connected in parallel to the lead wire, and has an inner diameter approximately equal to the width of the support member, and is inserted in the hollow portion. The transparent circular tube that fixes the support member and the outer circumference of the circular tube It is characterized in that it is composed of a cylindrical transparent colored sheet which surrounds.

Further, in the rod-shaped signal light according to claim 2, the grip portion and the hood are formed of a single transparent synthetic resin cylindrical body, and end reinforcing rings are fitted and fixed to the outer peripheral surfaces of both ends of the cylindrical body, It is characterized in that an intermediate portion reinforcing ring that also serves as a finger retaining ring is fitted and fixed to the outer periphery of the boundary between the grip portion and the hood, and lids are fitted and adhered to the inside of both end portions of the tubular body.

[Operation] Since the omnidirectional light-emitting bulb is used as a light-emitting body and is installed in the hole provided in the transparent synthetic resin band-shaped support member, the light emitted from the light bulb is emitted from the hole of the support member in both front and back directions. The light emitted and entering from the cut surface of the hole is diffusely reflected in the support member and emitted from the entire surface of the support member. Since the outer circumference of the support member is covered with a transparent synthetic resin circular tube and the outer circumference is surrounded by a transparent coloring sheet, the light from the light bulb is diffusely reflected and diffused in all directions by the circular tube to be transparently colored. Since the light is transmitted through the sheet and radiated outward and further transmitted through the transparent hood, the entire illumination body becomes a rod-shaped light emitting body. Therefore, since the light from the light bulb is directly transmitted to the outside, the effective reach distance of the light is large and the visibility is remarkably improved.

Further, even when the grip portion and the hood are formed of one synthetic resin cylinder, the reinforcing rings are fitted and fixed to the outer circumferences of both ends of the cylinder, and the lids are fitted and adhered to the inside thereof. The impact resistance of the end portions is increased, and damage such as dropping is prevented.

[Embodiment] Next, the present invention will be described with reference to the drawings.

In the rod-shaped signaling light according to the present invention (sometimes simply referred to as a signaling light), lids 2 and 3 are fitted and adhered inside both ends of one transparent synthetic resin cylinder 1 to seal the inside, Between the reinforcing rings 4a and 4c, by fitting and adhering the reinforcing rings 4a and 4b to the outer circumferences of both ends, and fitting and bonding the reinforcing rings 4c at positions separated by a length necessary to grasp with one hand from one end to the other end. The portion A constitutes the gripping portion A, and the portion between the reinforcing rings 4b and 4c constitutes the transparent hood 5 of the light emitting portion B.

Since the cylindrical body 1 is made of synthetic resin, its ends are inferior in impact resistance, but the lids 2 and 3 are fitted and adhered to the inside of both ends of the cylindrical body 1, and the reinforcing rings a and 4b are attached to the outer circumferences of both ends. Since they are fitted and fixed to each other, the mechanical strength of the ends is sufficiently reinforced, and damage such as dropping is prevented.

As shown in FIG. 2, a blinking circuit 6 and an illuminating body 7 connected to the blinking circuit 6 are housed in the hollow portion of the cylindrical body 1 that communicates from the gripping portion A to the transparent hood 5. The illuminator 7 is positioned and is held in the hood 5.

The illumination body 7 has a length substantially equal to the length of the hood 5,
The hood 5 and the hood 5 constitute a light emitting section B. This illuminating body 7 has a support member 9 formed in a flat strip shape from a transparent synthetic resin material in which conductors 8 are embedded in parallel at both ends in the width direction, and a hole provided at a position separated in the longitudinal direction of the support member.
An omnidirectional light-emitting bulb 11 housed in 10 and connected in parallel to the conductor 8 of the supporting member, and a tubular transparent colored sheet colored in red or orange surrounding the outer periphery of the supporting member.
It consists of 12.

More specifically, as shown in a partially enlarged view in FIG. 4, a large number of convex holes 10 are formed in the supporting member 9 at appropriate intervals, and a part of the pair of left and right conducting wires 8 is formed in each hole. The omnidirectional light-emitting bulb 11 such as a reddish neon miniature bulb is housed in the hole, and the electrode terminals 13 of the bulb are soldered or joined to the conductors 8 by caulking or the like to support the luminous body. It is arranged on the member 9. In this case, it is desirable that a part of the bulb of the light bulb projects from the hole 10 to the outside of both the front and back surfaces of the support member 9. Thereby, it is possible to irradiate light from one light bulb in all directions on both sides of the support member.
However, since the supporting member 9 is transparent, even if the light bulb is housed so as not to project outward from the hole, there is a diffusion effect in the irradiation direction and an effect of protecting the light bulb from external force in the process of assembling the signal light. can get.

The support member 9 in which the light bulb is arranged is surrounded by a transparent colored sheet 12. When the support member 9 is formed to be thin, when the width is smaller than the diameter of the transparent hood 5, the support member 9 may bend due to its own weight or when the signal lamp is shaken. In order to prevent this, the support member 9 is inserted and fixed in a transparent circular tube 14 having a diameter substantially equal to this width, and the circular tube is inserted through a cylindrical transparent coloring sheet 12. As a result, the support member 1 to which the light emitter is attached is held in a straight line. Also, a transparent circular tube
The light emitted from the light bulb is repeatedly reflected by the curved surface of the light bulb 14 to diffuse the light, so that the entire circular tube becomes like a rod-shaped light emitter.

Further, the coloring sheet 12 may be held by the inner peripheral surface of the hood 5, as shown by the dotted line in FIG. However, as shown in FIG. 2, when the outer peripheral surface of the circular pipe 14 is fitted, the consumption amount of the coloring sheet material can be remarkably reduced. The seat 2 has such a waist strength that it does not buckle under its own weight.

The ends of both conducting wires of the illuminating body 7 are electrically connected to the output side of the blinking circuit 6. On the input side of the blinking circuit, a socket 15 is provided which communicates from the lid 2 on the gripping section A side to the outside, and a plug at one end of a cord 16 can be connected to this socket. A connector (not shown) is provided at the other end of the cord 16, and the connector can be carried in a clothes pocket of a person who uses the signal light or attached to a belt or the like, and can be a dry battery or a rechargeable battery. It can be connected / disconnected to a DC power source such as a battery.

Thus, the signal light can be connected by cord 16 to a pocket or hanging power supply.

The blinking circuit 6 is, for example, a thyristor circuit composed of a combination of a capacitor and a resistor or a non-contact switch such as an oscillation circuit and a transistor, and changes the current from the power supply into an intermittent current of a certain frequency that can be visually confirmed. To give to 7.

The combination of the illumination body 7 and the blinking circuit 6 having the above-mentioned configuration is inserted into the hood 5 and the grip portion A before the lid 2 is attached, and the tip of the illumination body is pressed against the lid 3 to be fixed. By fixing the socket 15 and / or the socket 15 to the inner surface of the cylinder 1 and / or the lid 2, and fixing the lid 2 to the cylinder 1, the illuminating body and the blinking circuit are immovably mounted. In FIG. 2, 1
7,18 are reflectors.

With the above configuration, when a power source is connected to this signal light by the cord 16, the pulsating current is supplied to each miniature light bulb of the illuminating body through the blinking circuit 6, so that the light bulb blinks at a predetermined frequency. Since the light bulb is attached to the hole penetrating the support member 9, light is emitted from each light bulb to both sides of the support member.

Further, since the support member 9 is formed of a transparent material, the light emitted from the light bulb 11 to the cut surface of the hole of the support member passes through the material, and the portions between the holes of the support member and the adjacent holes. Since the light is emitted from the cut surface of, the whole support member becomes like a luminous body. Therefore, the radiant light amount distribution of the illumination body is made uniform in the longitudinal direction.

Therefore, to the viewer of the signal light, the entire light emitting portion looks like a rod-shaped light emitting body and blinks, so that the visibility of the signal light is improved and a remarkable appealing effect is obtained. Since the light bulb is surrounded by the transparent circular tube 14, the light generated from the light bulb is further diffused by the circular tube and radiated to the outside from the entire circumference of the circular tube. Therefore, this signal light has wide-angle visibility by using only one illuminating body.

In addition, since the reinforcing ring 4c between the grip portion A and the light emitting portion B has a finger-holding action, the tip of the finger gripping the grip portion can be stopped by hitting it, so that the signaling lamp can be easily gripped. Further, if all or part of the reflector 18 is removed, white light is emitted from the tip of the signal light, which can be used for reading characters on a document or for illuminating other objects.

When the support member 9 has such a thickness that it does not bend when the signal light is shaken, if the width of the support member is made substantially equal to the inner diameter of the cylinder 1 as shown in FIG. Since the support member 9 can be directly held in a straight line, the circular pipe 14 can be omitted, and the structure can be simplified. However, also in this case, the coloring sheet 12 is fitted to the inner circumference of the cylindrical body 1.

As shown in FIG. 1, in the preferred embodiment of the present invention,
An auxiliary band 19 is attached to the outer side surface of the grip portion A so that the fingers for gripping the grip portion can be pushed to the grip portion side. When the single cylinder 1 is used, it is not easy to attach the band 19, but since the reinforcing rings 4a and 4c are provided on both sides of the grip portion A as shown in FIG. The band 19 can be easily attached using the.

The auxiliary band 19 is formed of a material having a good texture, such as cloth, rubber, or soft synthetic resin, in the shape of a round cord or a flat belt, and preferably has elasticity. Accordingly, even when the force is removed from the hand holding the grip portion through the finger, the finger can hold the signal light only by the force of the auxiliary band. Therefore, when the hand holding this signal light for a long time becomes tired, the muscle used for grasping the hand is relaxed, so that the signal light can be prevented from dropping even if the hand is opened and closed occasionally.

In the above-described embodiment, the grip portion A is provided with only the blinking circuit 6 and does not have a power source as in the conventional case. However, in the present invention, the power source may be housed in the grip portion A in a replaceable manner.

[Advantages of the Invention] As described above, in the rod-shaped signal light according to the present invention, the illuminating body is configured by accommodating the omnidirectional light-emitting bulb in the hole provided in the support member made of transparent synthetic resin. Not only the front and back sides of the support member emit light, but also the support member emits light over the entire length, and the support member is inserted and fixed in a transparent circular tube, and the outer circumference of the circular tube is surrounded by a tubular transparent colored sheet for illumination. Since the body is configured, the circular tube further diffuses and diffuses light, and the entire illumination body becomes a rod-shaped light emitting body, so that the visibility is markedly improved and the appealing effect to the subject is large.

Further, since the supporting member has both the function of supporting the conductive wire and the light bulb and the function of diffusing light, the material cost is remarkably reduced, and the supporting member to which the light bulb is attached is inserted into one hood, Since the assembly is performed simply by inserting the tubular colored transparent sheet, the assembly is easy and the cost is reduced.

Further, according to the invention of claim 2, since the tubular body is made of synthetic resin, the end portions are inferior in impact resistance, but lids are fitted and adhered inside both end portions of the tubular body, and the outer peripheries of both end portions are reinforced. Since the ring is fitted and fixed, the mechanical strength of the end portion is sufficiently reinforced, and damage such as dropping is effectively prevented.
