Description

  The present invention relates to a safety vest, and more particularly to a vest that can be worn without a sense of incongruity and that is less likely to damage an LED.

  For example, many traffic guards and traffic directors (hereinafter simply referred to as traffic guides) are engaged in security and traffic guidance at road construction sites, and many police officers at traffic accident sites and traffic control sites. Are active. Such traffic directors and police officers are required to wear a safety vest because they must be clearly and surely visible to the driver of the vehicle at night.

  Conventionally, in this type of safety vest, the vest is sewn using a base material such as fabric or mesh, and a belt-like retroreflective sheet is attached to the chest and back by sewing or welding, and the vehicle headlight is received at night. Thus, the presence of traffic guides and police officers can be recognized (Patent Document 1, Patent Document 2).

  However, in the safety vest using a retroreflective sheet, the retroreflective sheet does not reflect light and is difficult to be visually recognized unless light from the vehicle headlight is irradiated.

  On the other hand, a safety vest has been proposed in which a plurality of LEDs are attached at intervals before and after the front body, and light is emitted by energizing the LEDs regardless of the light from the vehicle headlights ( Patent Document 3 and Patent Document 4).

  However, in the safety vest described in Patent Documents 3 and 4, since a plurality of LEDs are attached at intervals in the front and rear bodies, the LEDs protrude from the front and rear bodies, and the LEDs collide with each other and may be damaged. There was a problem that the LED hit the chest and back and felt uncomfortable.

  This invention makes it a subject to provide the safety vest which can be worn without a sense of incongruity and made LED hard to be damaged in view of this problem.

  Therefore, the safety vest according to the present invention is a safety vest in which a belt-like retroreflective sheet is attached to the front and back of the vest obtained by cutting and sewing the fabric, and the retroreflective sheet transmits light emitted from the back side forward. A light emitting cable that is made of a sheet material, and is configured by coupling LEDs to both ends of an optical fiber that allows a part of the light propagating through the core to pass through the clad between the retroreflective sheet and the front view or the back view Inserted into the LED of the light-emitting cable, the other end of the power-supply line is connected to a power source, a switch is provided between them, and the lighting or flashing of the light-emitting cable passes through the retroreflective sheet. It is characterized by being visible.

  One of the features of the present invention is that the retroreflective sheet is made of a sheet material that can transmit the light emitted from the back side forward, and light is emitted by coupling LEDs to both ends of the optical fiber between the retroreflective sheet and the front or back view. The cable is inserted, and the LED is turned on or blinked to light the entire light emitting cable.

  As a result, the LED is positioned on the shoulder and waist of the user of the safety vest, and there is less risk of the LED hitting an obstacle or the like, and the LED hits the user's chest or back and feels uncomfortable. There is nothing.

  The light-emitting cable is obtained, for example, by configuring so that light propagating through the core of the optical fiber is not totally reflected by the clad of the optical fiber, but partially transmits through the clad.

  The light emitting cable may be inserted between the retroreflective sheet and the front view or the back view, but a storage space for the light emitting cable is preferably provided on the back side of the retroreflective sheet.

  That is, by laminating a narrow strip film on the back surface of the retroreflective sheet and fixing both side edges to the retroreflective sheet over the entire length in the length direction, a storage space is provided between the retroreflective sheet and the strip sheet. It is preferable to configure and insert a light emitting cable and a conducting wire into the storage space.

  Further, by laminating a strip-like film of the same width on the back surface of the retroreflective sheet, and fixing the strip-like film and the retroreflective sheet linearly continuously or discontinuously over the entire length in the length direction at a predetermined interval. A storage space can be formed between the retroreflective sheet and the belt-like sheet, and a light emitting cable and a conductive wire can be inserted into the storage space.

  When a belt-like film is stacked on the back surface of the retroreflective sheet, if the belt-like film is configured so as not to transmit light, the amount of light to the front increases and it becomes easier to visually recognize.

  The vest fabric is not particularly limited, and for example, a cloth using a synthetic resin yarn or a natural material yarn, or a mesh fabric made of a synthetic resin or a natural material can be used.

1 is a front view showing a preferred embodiment of a safety vest according to the present invention. It is a rear view which shows the said embodiment. It is a figure which shows the storage space and light emitting cable in the said embodiment in the said embodiment. It is a figure which shows the structural example of the light emitting cable in the said embodiment. It is a figure which shows the example of the LED drive circuit in the said embodiment.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 5 show a preferred embodiment of a safety vest according to the present invention. In the figure, the vest 10 is cut into a sheet shape in which a front view 11 and a rear view 12 are developed using a black mesh fabric made of a synthetic resin material as a base material.

  A belt 13 made of, for example, a retroreflective sheet having a width of 70 mm is attached to both sides of the body portion of the front viewing time 11 and the rear viewing time 12 by stitching the both side edges. A hook-and-loop fastener 14 is fixed to the front view 11 on the back side of the end portion by sewing or the like, and the left and right of the front view 11 can be coupled to each other by fastening the hook-and-loop fastener 14 to each other. Further, the peripheral edges of the front viewing time 11 and the rear viewing time 12 are covered with a hem and sewn.

  For example, a belt-like white retroreflective sheet 15 having a width of 70 mm extends obliquely from the center of the body portion of the front view 11 to both shoulders, and further from the shoulders to the back body 12 of the back body 12. It is arranged to extend obliquely toward the center, and is sewn and pasted with a suture thread. On the back side of the retroreflective sheet 15, a strip-like film 16 having the same width as that of the retroreflective sheet 15 made of a material that hardly transmits light is overlapped, and both side edges thereof are stitched together with both side edges of the retroreflective sheet 15.

  The retroreflective sheet 15 and the belt-like film 16 are continuously fixed linearly over the entire length in the length direction at a predetermined interval in the center, whereby the storage space 17 is provided between the retroreflective sheet 15 and the belt-like sheet 16. Are formed in the storage space 17 from the center of the trunk portion of the front view 11 to the shoulder portion of the rear view 12, and the storage space 17 from the shoulder portion of the rear view 12 to the center of the trunk portion is provided with the light emitting cable 20 and the conducting wire 21. Has been inserted.

  The light emitting cable 20 is configured by coupling the LED 22 to both ends of the optical fiber 21 in which a part of the light propagating through the core 21A can pass through the clad 21B, and the entire light emitting cable 20 is turned on or blinks by energizing the LED 22. It has become.

  As shown in FIGS. 5 and 6, the LED 22 is connected to the energization line 23 and is connected to the control circuit 26 of the energization line 23, and the control circuit 26 is connected to the power supply 24 via the switch 25. When the switch 25 is closed, the control circuit 26 energizes the LED 22 with a constant or pulsed direct current so as to light or blink the LED 22.

  For example, at night, when a traffic director, a traffic guard, a police officer, etc. wearing the safety vest 10 of this example closes the switch 25 (ON), the light emitting cable 20 is turned on or blinked, and the light emission is performed. Since it can be visually recognized through the retroreflective sheet 15, the driver of the vehicle illuminates forward traffic guides, traffic guards, police officers, etc. with the vehicle headlight, and the reflected light of the retroreflective sheet 15 and the lighting of the LED 22 or By flashing, the presence of traffic guides, traffic guards, police officers, etc. can be confirmed reliably.

  Moreover, in the safety vest 10 of this example, the LED 22 is located near both shoulders of the waist and the back, so that the LED 22 is not damaged by hitting anything, and the LED 22 does not hit the wearer's body and gives a sense of incongruity.

  Although the strip-like film 16 has the same width as the retroreflective sheet 15 in the above, both side edges may be fixed to the retroreflective sheet 15 as the width of the storage space 17, and the strip-like film may not necessarily be provided.
