Description

The present invention is an invention related to a working vest that is used by emitting light.

For example, at road construction sites, workers often wear vests that reflect the illumination of automobile lights when they work. However, the reflector may not reflect depending on the irradiation angle. In addition, the light was weak and could not be recognized by a driver approaching at high speed from a distance.

Therefore, there is a case where a work vest in which a light emitting member such as a miniature bulb or an LED light is arranged is used instead of a simple reflector. However, when the light emitting members are arranged on the back body together with the front body, it is necessary to perform complicated wiring according to the arrangement of a plurality of light emitting members. There is a risk that the wiring will be broken by moving the body during construction work, and since the wiring is continuous, it may be necessary to replace the entire wiring due to a partial disconnection. Therefore, the cost of replacing the work vest is high.

Therefore, there has been a demand for a work vest having a wiring structure that does not easily break and an arrangement of light emitting members that facilitates replacement.

Provided is a working vest comprising a tape-shaped light source whose other end is terminated by a non-light emitting member and which is used by emitting light.

Next, as a second invention, the storage band is formed by joining a long film on the vest body side and a transparent long film laminated thereto at both ends in the width direction, and the long film on the vest body side. The transparent long film side provides a working vest according to the first invention, which is composed of a member having a light reflecting function and is used by emitting light.

<Explanation of Embodiment 1 Configuration>
<Embodiment 1 Best Body>
The "vest body" is a cloth-like member on which all the components in the present embodiment can be arranged. 3 to 8 are views showing an example of the configuration of the vest main body in the present embodiment. For example, as shown in FIG. 3, it is conceivable that the left and right sides are closed near the waist of the front body. As a closing means, as shown in FIG. 4, a hook-and-loop fastener (0401) can be considered. By using a hook-and-loop fastener structure, it can be worn by people with a certain width. Further, as shown in FIGS. 3 and 5, it is conceivable that the members (0301, 0501) having a light reflecting function make one round around the waist of the vest body. By arranging the member having the reflecting function, the reflected light can be irradiated even in the portion where the tape-shaped light guide body is not arranged, so that the overall light emitting area can be increased. Further, as shown in FIG. 6, the rear view is configured to substantially cover the back. On the other hand, as shown in FIG. 7, it is conceivable that the front body has a large open chest. With such a configuration, the vest body is stable because it is in wide contact with the human body on the back surface, and it is less likely to shift when worn. By widening the chest of the front body, even if the contact area of the back part with the human body is large, it is alleviated that it becomes tight as a whole or it becomes difficult to move the body. Further, as shown in FIG. 8, it is preferable that the areas other than the waist members are wide open on the left and right body sides. In this case, the waist area is removable by the hook-and-loop fastener near the left and right waist. It is conceivable to connect to. By making it removable with a hook-and-loop fastener, it is possible to provide an appropriate fit to a wide range of people. In the work vest of the present embodiment, the back surface of the vest near the abdomen is provided with means for holding the respective light source boxes independently on the left and right sides. The light source box held here has the chest and left and right parts of the vest body wide open so that the left and right hands can be easily reached even when worn. Also, it is preferable to border any end of the vest with bias tape. By edging with bias tape, the threads on the cross section of the cloth-like member are less likely to fray.

<Embodiment 1 Light Source Box>
The "light source box" is arranged on the back surface of the vest body to hold the end of the tape-shaped light guide, and to introduce light from the end of the tape-shaped light guide, and to emit light from the light source. It has a power supply and. Since it is placed on the back side of the vest body, it prevents dust and water droplets generated during work from entering the light source box. If dust or water droplets get inside the light source box, it may cause electric leakage or rust, and the function of the light source box may be impaired. Holding the end of the tape-shaped light guide indicates that the end of the tape-shaped light guide is housed in the light source box. There is one light source box corresponding to one tape-shaped light guide. Therefore, the light source box is connected only to one end of the tape-shaped light guide.

As a method of storing the end of the tape-shaped light guide in the light source box, a gap through which the tape-shaped light guide can enter is created in the light source box, and the gap through which the tape-shaped light guide can enter is used as an entry port to guide the tape. A method of inserting a light body is conceivable. Alternatively, when the light source box can be opened and closed, a groove for arranging the tape-shaped light guide is formed in the lid and / or the box body, and the box lid is sandwiched after the tape-shaped light guide is placed. By closing it, it is conceivable that the end portion of the tape-shaped light guide body is housed in the light source box. By storing the end of the tape-shaped light guide in the light source box, the light source situation can also be stored in the light source box. Since the light source may be cracked by an impact, it can be expected to be highly effective in preventing damage by storing it inside the light source box. Further, since it is possible to store all of the light source, the power supply, and the wiring in the light source box, the wiring distance is minimized, the exposed wiring is eliminated, and the risk of disconnection during work is greatly reduced. In addition, since everything is housed in the light source box, the risk of damage or disconnection of each member due to impact during work is greatly reduced.

FIG. 9 shows holes (0903) provided on the left and right sides near the tip of the tape-shaped light guide body (0902), which is an example of the light source box (0901), in the tape-shaped light guide body guide groove (0904) of the light source box body. ) Is passed through the two protrusions (0905) to fix the tape-shaped light guide to the main body of the light source box. Most preferably, the light source box is made entirely of plastic and is configured to be waterproof. As an example, the exposed part of the light source (0906) is a transparent plastic lens, and after arranging the tape-shaped light guide as described above, the upper sliding lid is slid to only the tape-shaped light guide. It is configured to extend from the light source box. In this case, it is preferable that the internal power supply of the light source box is configured to be charged by a non-contact charging mechanism so that it cannot be opened or closed. However, charging may be configured to be contact-charged by the only exposed airtight terminal. As a result, the structure can be made strong against shock, vibration, dust, water droplets, and the like. In addition, the hole may easily come off from the protrusion simply by passing the hole made in the tape-shaped light guide through the protrusion. Therefore, as described above, in order to prevent the tape-shaped light guide from coming off. , It is conceivable to cover with a sliding lid (0907). In the sliding lid, when the tape-shaped light guide is movable along the protrusion, the amount of light source incident on the tip of the tape-shaped light guide becomes unstable, and the light emission intensity of the tape-shaped light guide becomes unstable. Becomes unstable. Therefore, it is preferable that the gap between the sliding lid and the tape-shaped light guide is as small as possible. As shown in FIG. 10, it is preferable that the structure is such that the tape-shaped light guide body (1003) housed in the light source box (1002) is pressed by the sliding lid (1001).

Further, it is preferable that the light source box is configured to be detachable from the vest body. Charging can be easily performed by making it removable. This point, coupled with the fact that the tape-shaped light guide is detachable from the light source box, facilitates charging. The detachability of the light source box from the vest body can be achieved by, for example, arranging a hook-and-loop fastener on one side of the light source box and arranging a pair of hook-and-loop fasteners at a predetermined position on the back surface of the front body of the vest body. In addition, it is conceivable to provide a pocket capable of storing the light source box at a predetermined position on the back surface of the front body of the vest body and put it there. When using a pocket, for example, when the body posture is upside down, there is a danger that the light source box will come off the pocket due to gravity, but the vest body is free and extends on the back side of the front body. If the length of the light guide body is sufficiently shortened, the portion will not be bent, so that the danger does not occur even in an upside-down posture. Although it depends on the thickness of the tape-shaped light guide, if the thickness of the tape-shaped light guide is within the range of 2 mm to 5 mm, the length of the free tape-shaped light guide is about 3 cm to 6 cm. It should be. If it is shorter than 3 cm, it becomes difficult to separate the light source box from the pocket, and if it is longer than 6 cm, the free portion bends and the light source box is freely separated. It is preferable that the pocket has an opening at the top when a person wears a work vest. It is also conceivable to add a lid cloth to the pocket so that the light source box does not come off freely.

The light source in the present embodiment is assumed to be an LED light source, but may be a light source other than the LED light source as long as it emits light with an illuminance capable of guiding the tape-shaped light guide. As an alternative to the LED light source, an organic EL light source, a plasma light source, various light bulbs, and the like can be considered. It is desirable that the light source emits light with stable illuminance for a long time with low power consumption. The LED light source is suitable because it saves power and emits light with a stable illuminance. In the case of a light source that lights or blinks at a point like a light bulb without using a tape-shaped light guide as in some conventional techniques, it is clearly recognized at least 10 cd to recognize its existence from 100 m away in the dark. It is believed that 15 cd is required for this. This is because point light sources are difficult for the human eye to recognize. On the other hand, if it is a flat light source, it can be easily recognized by the human eye, and if it is a flat light emitting body, it may be about one-third to one-fourth of that of a point-shaped issuer. In order to illuminate a transparent plastic having a length of about 1 m to 1.5 m on average about 2 cd to 5 cd, it is sufficient that the brightness is about 6 cd to 15 cd near the contact point of the tape-shaped light guide body of the light source box. .. This is bright enough to be filled with a few LED light sources.

Generally, as the cd value increases, the amount of power consumed per unit time increases, so that the amount of battery consumption increases. When the battery consumption increases, the continuous usable time is extended by increasing or increasing the battery, or the battery is frequently replaced. In the former case, since the size and weight of the light source box become large and heavy, it tends to get in the way during work, which increases the burden on the operator. On the other hand, in the latter case, the cost is high, and there remains anxiety that it is not possible to know when the energy will run out when working for a long time. When the effect can be expected even with a light source having a relatively small cd value as in the present embodiment, the battery consumption is relatively small, so that it is necessary to increase the battery, and many batteries are used. You don't even have to. Therefore, since the light source box does not become relatively large, it does not get in the way so much during the work, and the burden on the operator can be small. Furthermore, since the continuous usable time is relatively long, there is no need to worry about running out of energy during work. Of course, also in the present embodiment, by using a light source having a brighter illuminance, the visible distance becomes longer and the safety can be further improved. Therefore, it is recommended to use a light source having a larger cd value. It can be said that it should be done.

The color of the light source is not particularly limited. The light source may be configured by one LED light or may be configured by combining a plurality of LED lights. For example, depending on how the plurality of lights are combined, it is conceivable to combine lights having different colors so that the emission color can be selected by switching the switch arranged in the power supply box. It is more noticeable that a plurality of colors shine at the same time or a plurality of colors shine alternately than a single color, so that the wearer's recognizability can be enhanced. Alternatively, for example, it is possible to indicate the content of caution by the color of the light, such as blinking in blue when indicating that there is a water leak, or blinking in red when cautioning against collapse. Even when communication is difficult, it is possible to appropriately alert workers.

<Embodiment 1 Tape-shaped light guide body>
The end of the "tape-shaped light guide" is held by the light source box, and the storage band is formed from the vest insertion hole provided on the back surface of the front body of the vest body through the storage band insertion hole provided on the back surface of the storage band. And the other end is terminated with a non-luminous member. As shown in FIG. 2, the "vest insertion hole" (0207) is a vest body formed for inserting the tape-shaped light guide into the band of the storage band provided in the vest body. It is a hole made in. The "storage band insertion hole" (0203) is opened on the storage band vest side opened for inserting the tape-shaped light guide into the inner band of the storage band material on the vest body side. It is a hole. The vest insertion hole and the storage band insertion hole may be opened at different positions so as not to overlap each other, but in order to facilitate the insertion of the tape-shaped light guide, the vest insertion hole and the storage band insertion hole and the storage band are as shown in FIG. It is preferable that the band insertion holes are drilled at the same position so as to overlap each other.

One end of the tape-shaped light guide is held inside the light source box arranged on the back surface of the vest body as described above. Therefore, most of the tape-shaped light guides are arranged on the outer front side of the vest, but one end thereof is arranged on the back side of the vest body in which the light source box is arranged. It is required to have a configuration that penetrates the vest body so that it can rotate to the back side of the vest body. The vest insertion hole is preferably arranged near the lower body side of the vest body in order to make the visible light emitting surface as long as possible. In order to lengthen the most visible light emitting surface, the vest insertion hole is arranged at the switching portion between the front body vest surface and the front body vest back surface. Even in that case, it is preferable to arrange the light source box at a position where it is covered by the back side of the vest body.

The tape-shaped light guide body is a tape-shaped band-shaped material capable of introducing light into its cross section from a light source installed at an end portion and guiding light from the light source installation side end portion toward a paired end portion. .. It has a function similar to that of a light guide plate of a so-called liquid crystal display. That is, it has a light diffusion function as well as a light guide function. Since the scattered light tends to be stronger near the light source, the light diffusion function can make the light emission of the light guide body uniform by weakening the side near the light source and strengthening the side far from the light source. The strength of the light diffusion function can be adjusted by, for example, the size of the emboss formed on the surface (emboss diameter large → small: diffusion function weak → strong), or the strength of the surface roughness (surface roughness small → large: diffusion function). It is possible by adjusting (weak → strong). Since the surface of the tape-shaped light guide body facing the vest main body side does not need to diffuse light, it can be designed to have a surface texture different from that of the front side. That is, it is preferable that the surface treatment on the side of the tape-shaped light guide body facing the best surface is designed so as to totally reflect the light emitted from the tape-shaped light guide body toward the surface as much as possible. That is, it is preferable that the surface is made of a material having a refractive index smaller than that of the material of the core portion without having a light diffusing function.

It is conceivable that the material constituting the tape-shaped light guide body in the present embodiment has a sheath structure as shown in the cross-sectional view of FIG. It is conceivable that the material of the core portion (1101) is made of an acrylic resin containing PMMA or the like, and the material of the sheath portion (1102) is made of a light-transmitting material containing milky white fluorine. The length of the core portion a is 10 mm or more and 20 mm or less, the thickness is 1 mm or more and 5 mm or less, and as shown in FIG. 2, it may be formed by an ellipse or formed on a polygon. You may be. The sheath portion has a size and shape that closely covers the core portion, and has a thickness of 0.1 mm or more and 0.4 mm or less.

<Embodiment 2>
<Characteristics of Embodiment 2>
In the invention of the present embodiment, in addition to the features described in the first embodiment, the configuration of the storage band for accommodating the tape-shaped light emitting band is such that the width of the vest body side long film and the transparent long film superimposed on the vest body side long film. It is joined at both ends in the direction, and the transparent long film side of the long film on the vest body side is made of a member having a light reflecting function.

<Structure of Embodiment 2 Invention>
As shown in FIG. 12, the storage band of the invention of the second embodiment is formed by joining a long film (1201) on the vest body side and a transparent long film (1202) superposed on the long film (1202) at both ends in the width direction. The transparent long film side (1203) of the long film on the vest body side is made of a member having a light reflection function.

<Explanation of Embodiment 2 Configuration>
<Embodiment 2 Best body side long film>
The "vest body side long film" is a member fixed to the vest side, and the surface side thereof is composed of a member having a light reflection function. As described above, since the tape-shaped light guide is transparent or translucent, the light diffused from the tape-shaped light guide leaks not only to the front side but also to the vest side. However, by configuring the surface side of the long film on the vest body side to have a light reflection function, the amount of light absorbed by the vest body side can be reduced unnecessarily.

Further, for example, when the tape-shaped light guide is worn by a road worker, the tape-shaped light guide is irradiated by the headlight of an automobile approaching the vicinity, but as described above, the tape-shaped light guide is transparent or Since it is made of a translucent material, it reaches the surface of the long film on the vest body side without being attenuated by the tape-shaped light guide. Therefore, since this portion has a light reflection function, it is possible to reflect the external light emitted to the tape-shaped light guide body such as the light of the headlight of an automobile, and the visibility can be further improved. ..

<Embodiment 2 Transparent Long Film>
The "transparent long film" is for covering the tape-shaped light guide while transmitting the light of the tape-shaped light guide housed in the storage band and fixing it to the work vest. Therefore, it is required to be a highly transparent film. Further, since it is a member located on the outermost side, it is preferable that it also has strength. Further, when dirt is attached, it is preferably made of a material having high antifouling property so that the dirt can be easily removed by wiping it off.

Further, the tape-shaped light guide body retains light energy, and heat is generated when a part of the light energy becomes heat energy. Therefore, the temperature inside the storage band may be higher than the temperature of the outside air, and in that case, there is a risk of dew condensation occurring inside the storage band. If condensation forms, there is a risk that water droplets will enter the inside of the light source box and cause an electric leakage. In order to prevent dew condensation, the inside of the storage zone should be configured so that air can enter and exit so that it does not become too warm. The transparent long film is preferably made of a material that does not hinder the exchange of air.

Examples of materials constituting the transparent long film include plastic materials and resins including agricultural polyolefin films (agricultural poly, PO film), fluororesin films (hard films), fluoropolymers, thermoplastic elastomers, and the like. The material can be considered. These are breathable and water resistant.

<Embodiment 3>
<Outline of Embodiment 3>
The invention in the present embodiment is characterized in that, in addition to the features described in the first or second embodiment, the material of the vest body is made of an antifouling mesh material.

<Structure of Embodiment 3 Invention>
In the present invention, the vest body is made of an antifouling mesh material. The work vest has a structure that is inherently vulnerable to water because the light source box is arranged and the tape-shaped conductor is arranged from the front body to the back body. It is certainly possible to wash only the vest body by separating the light source box and the tape-shaped conduction band from the vest body, but as shown in the case of the second embodiment, the storage band is made of a reflector and a transparent member. If configured, there is a risk of deterioration of these. From this, it can be said that washing should be avoided as much as possible, and it is preferable to use an antifouling material. It is also made of a mesh material in order to enhance the effect of preventing stains. When using a mesh, most of the dirt passes through the holes in the mesh and does not adhere to the vest body. Therefore, the dirty area situation can be minimized.

Furthermore, since the body is moved during work, the body temperature tends to rise and sweating tends to be promoted. Therefore, by using a mesh material, ventilation is improved and the effect of preventing heat buildup can be expected. The material used is preferably a chemical fiber that is resistant to putrefaction and deterioration and has high water repellency. For example, polyethylene-based materials such as high-density polyethylene, polyamide-based materials such as nylon, and polyester-based materials such as tetron may be used as materials. ..

<Embodiment 4>
<Outline of Embodiment 4>
The invention in the present embodiment is characterized in that, in addition to the features of the first to third embodiments, the width range of the tape-shaped light guide is limited.

<Structure of Embodiment 4 Invention>
When the width of the tape-shaped light guide is W and the width of the storage area of the storage band is T,
1.5W ≤ T ≤ 2.5W
It is configured to satisfy the relationship of.
It is preferable that a maximum of two tape-shaped light guides can be stored in the storage band. When composed of two tape-shaped light guides, the luminous intensity can be increased as compared with the case where the same width is configured by using one tape-shaped light guide. Therefore, the wearer can be made more conspicuous. If two or more tape-shaped light guides are used in one step, the width of the light source box will inevitably increase and the number of light sources will increase due to the convenience of arranging the light sources at the ends of each tape-shaped light guide. As a result, the power consumption increases, and the amount of batteries arranged in the light source box is increased or the continuous usable time is shortened. From the above, it is most suitable to be composed of at most two tape-shaped light guides.

<Embodiment 5>
<Outline of Embodiment 5>
In addition to the features of the third or fourth embodiment based on the second embodiment or the second embodiment, the invention in the present embodiment includes a long film on the vest body side constituting a storage band and a transparent long film superimposed on the long film. It is characterized in that the bonding at both ends of the film is a double or more bonding.

<Structure of Embodiment 5>
The long film on the vest body side that constitutes the storage band and the joints at both ends of the transparent long film that is layered on it are each composed of double or more joints. FIG. 13 is a diagram showing a case of double joining of the present embodiment. A and b shown in the figure are joints at both ends and are doubled. By making it double, it is possible to prevent the seam of the storage band from being torn when the tape-shaped light guide body is taken in and out of the storage band.

<Embodiment 6>
<Outline of Embodiment 6>
In the invention of the present embodiment, in addition to the features described in any one of the first to fifth embodiments, the storage band insertion hole and the vest insertion hole are arranged more than half in the height direction of the front body, respectively. It has the characteristic of being.

<Structure of Embodiment 6 Invention>
The invention in the present embodiment is configured such that the storage band insertion hole and the vest insertion hole are arranged more than half in the height direction of the front body, respectively. Since it is placed below half in the height direction of the front body, it is possible for a person other than the wearer to see the light emission of the tape-shaped light guide body at least up to half the height direction of the front body when wearing the vest. It becomes. As the visible length of the tape-shaped light guide becomes shorter, the effect of calling attention to the wearer becomes weaker. It is preferable to arrange it.
