Description

    The present invention relates to a helmet covering capable of notifying danger, and to a helmet equipped with the helmet covering.

    Conventionally, helmets or protective caps are used for various purposes such as construction sites, disaster sites, motorcycles, etc., and basically provide safety to the wearer's head. Depending on the purpose used, different conditions such as strength must be satisfied. These helmets and protective caps have been proposed in various ways for the wearer's safe and free multifunctional behavior, or for providing safety to the wearer more widely beyond the head. ing.

For example, in the case of a construction site, the supervisor monitors the surrounding situation, and when a dangerous situation is likely to occur, the worker is informed of the danger to ensure the safety of the worker. Yes. For example, the supervisor has been devised to notify the dangerous state using radio, and as disclosed in Patent Document 1, the supervisor incorporates a radio device into a conventionally used guide light. In addition, the use of wireless is further added to the conventional danger notification method to improve the danger avoidance of the worker. Alternatively, as described in Patent Document 2, a device that enables communication between guide lights is also devised.

    The present inventors have attempted various improvements and improvements in view of the fact that these conventional methods have not yet sufficiently avoided danger and are still reporting on various accidents. For example, a radio alarm device was incorporated into a helmet to be worn at a construction site and tried to be used in addition to the conventional safety improvement method. I found it best to communicate. However, this method cannot be used to confirm whether or not all of the workers at the construction site knew each other's danger prediction, and the supervisor or the supervisor who made the dangers said the worker or all workers There was a problem that it was not possible to confirm whether the prediction was confirmed. In addition, a plurality of light emitting devices combined with a reflective portion that reflects light emitted from the light emitting portion in multiple directions are incorporated into a construction vest worn during construction, and the operation of the light emitting device makes it dangerous for the workers. We also tried a method to confirm the prediction. However, none of them are sufficient, and further improvements are necessary, and various attempts have been made.

    In such an improvement trial, the present inventors are detachable from the helmet and, when attached to the helmet, are coverings that cover at least a part of the outside of the helmet, and include a plurality of light generating portions. It has been found that a helmet covering having a plurality of reflecting portions that reflect light generated from the light generating portion around the outside of the helmet is very effective.

    The main body of the covering body of the present invention is basically formed in a belt shape, a hat shape or the like using plastic, cloth or the like as a material, and at least a part of the body is firmly fixed to the helmet when worn. Is configured using a fixing tool (for example, a buckle such as a belt) that is elastically fixed to the helmet or detachable, and is detachable when not required. The substrate, the light emitting device, and the reflecting device used in combination with the light emitting device are used as the main body, the light emitting unit, and the reflecting unit, respectively.

    The light emitting unit and the reflecting unit are arranged on the main body. Preferably, there are a plurality of the light emitting units and the reflecting unit, respectively, and light emission can be seen from any angle when viewed from the surroundings when worn on the helmet. In this way, it is arranged so as to surround the helmet. The reflecting part is disposed below the light emitting part, and preferably, the light emitting part is sandwiched between the transparent fluorescent part and the reflecting part, and is fixed to a support part provided on the reflecting part. The transparent fluorescent part is preferably a yellow light-emitting phosphor kneaded with a transparent resin or the like. From the viewpoint of recognition, a yellow light-emitting phosphor that is most easily seen is generally preferable. It is also possible to use a phosphor emitting red light, for example, by alternately arranging a plurality of the light emitting parts covered separately with a yellow light emitting body and a red light emitting body, In addition to the distinction, it can be configured so that the use of a large number of signals can be clearly distinguished by the proper use of yellow and red colors.

    Preferably, the light emitting part and the reflecting part are preferably configured so that they can be arranged also on the upper part of the helmet so that they can be seen from above the helmet. Even in the shape of surrounding, it can be seen from above because of the inclination. Therefore, it is preferable that the light emitting portion and the reflecting portion are configured to be visible from at least the front, rear, left, and right of the user who wears the covering on the helmet.

    As the light emitting part, a light emitting element having a small size and high luminous efficiency such as an LED is used, and as the reflecting part, those already used in the waistcoat as described above are preferably used. Reflectors used in the reflecting portion are used in various things, for example, used for attaching to a bicycle tire cover or school bag. In addition, it is preferable to use one that is easy to recognize the reflection of light even from a distance and is used for improving safety. The light emitting elements are electrically coupled to each other, or when using the resulting multi-color combination, for example, the light emitting elements having the same color when viewed from the outside are electrically coupled to each other for power supply. A terminal to be connected is provided, or connected to a power source via a control device that controls on / off, for example, blinking, lighting, and the like.

    Accordingly, the covering body may have a power source connected to the front light emitting unit, and the power source is configured to be worn separately on a user's waist, shoulder, chest pocket, etc. The covering may have a terminal connected directly or indirectly to the separate power source. In the case of a separate body, the control device can be configured to be integrated with a power source so as to be separate from the covering body. The power source preferably has a large capacity and is preferably a rechargeable secondary battery, but preferably has a small or light volume. Moreover, it is also possible to divide and arrange them as the covering body and the separate body. For example, a plurality of AAA rechargeable batteries can be used and divided, for example, to reduce the load on each body part.

    The covering may include a receiving device connected to the power source. The receiving device receives a signal from a transmitting device, for example, a transmitting device of a construction supervisor, and transmits a signal of contents to be controlled to the control device. For example, in the case of track construction, the construction supervisor monitors the movement of the construction worker, and always generates a danger signal when the train approaches. When the receiving device receives the danger signal, the operation of the control device is started, and the light emitter is caused to blink, for example. As a result, surrounding construction workers confirm each other's danger. At this time, the distance to the train and the meaning of the change in blinking and lighting, or the change in color, etc. are determined by the distinction between blinking and lighting or the color of blinking. You can also notify or recognize your level.

    Similarly to the control device, the receiving device can be separated from the cover, and preferably, the power source, the control device, and the receiving device are integrated into a separate body. Desirable above. Based on the signal from the receiving device, the control device controls on / off of the light emitting element. Depending on the type of the signal, control of lighting, blinking, etc. and which light emitting element is controlled. Control can also be performed. For example, in the case of the covering capable of generating two colors of yellow and red, yellow can be turned on and red can be blinked. Thereby, it can be notified that the danger is imminent. In this way, the urgency of danger avoidance can also be notified.

    The covering may include an oscillation device. The oscillating device preferably oscillates in response to a signal from the receiving device, and more preferably transmits vibrations to the helmet in synchronization with the operation of the light emitting device. Can inform you of the danger. For example, the construction site has a strong ambient sound, so even if the sound is erased by the noise and cannot be heard, the head can feel the vibration and know the operation of the oscillation device.

    The method of notifying the user of the helmet wearing the covering body of the danger can also use the oscillation device and / or the light emitting body. For example, the shape of the covering body is devised, If the light emitting part is provided at both the upper and lower parts of the base of the collar part in such a manner that the tip of the collar part is passed through, the light emitting part at the lower part emits light and the use is performed. The person himself / herself can be aware of the danger as well as its danger level.

    Alternatively, the user himself / herself knows the danger by providing a transparent part at the base of the heel part of the helmet and knowing the light emission of the light emitting part outside the helmet through the transparent part. it can. Of course, the combined use of the oscillation device and the light emission notification means to the person enables the helmet user to know the danger more reliably and also informs the surroundings of the danger and the user recognizes the danger. It is possible to inform the surroundings of the situation.

    The present invention also relates to a helmet or protective cap equipped with the covering. The helmet may incorporate the power supply in addition to, or instead of, the covering and / or the separate body. Furthermore, the helmet may incorporate the receiving device and / or the control device. The helmet can also incorporate the oscillation device. The mutual relationship and operation of the power source, the receiving device, the control device, and the oscillation device can be configured to have the respective relationships as described above. In addition, the helmet can also incorporate a transmission device, and when receiving a notice of danger from the supervisor, other operations that operate the transmission device and are unable to receive the same work. It is possible to prevent the reception omission by transferring the signal from the supervisor or transmitting the same signal to the supervisor.

    Since the present invention is configured as described above, the progress of the work situation and the supervisor or supervisor who monitors the surrounding situation, the movement of the light reflected on the reflection portion, the position of the worker, In addition to being able to recognize the movement, placement, etc. from a distance, in addition to risk avoidance efforts by confirming the plan progress status of the workers themselves or colleagues and attention to changes in surroundings, notification of the danger status by the supervisor or the supervisor So that you can work more safely. Moreover, it becomes safer by the notification of the danger level. It is possible to confirm the danger and the level of each other and the operator by a combination of colors depending on the blinking or lighting of the illuminator mounted on the helmet.

    In addition, in the case of a waistcoat with a light emitter, it becomes possible to confirm cases where the worker is hidden and difficult to check because of the work equipment, and it is also possible to work while sitting in a leaning position. In addition, a case where the waistcoat is hidden and a mutual confirmation could not be made is possible, such as confirmation from the height of the helmet or confirmation from the top of the helmet has been made possible. . Especially in the case of night work such as night work and night disaster site work, the safety confirmation effect is higher.

    In addition, it is not necessary to attach to all helmets in advance, and since it can be attached when necessary by work, the generation of unnecessary costs can be suppressed. In addition, since the worker can always wear his / her helmet, there is an advantage that safety in terms of hygiene is ensured. Therefore, the covering according to the present invention has various excellent effects, but other effects will be further clarified from the following description.

    Hereinafter, the present invention will be described more specifically with reference to the drawings, and specific examples will be described. 1 to 4 show an embodiment of the present invention. 1 is a side view of a helmet equipped with a covering according to the present invention, FIG. 2 is a plan view of the helmet, FIG. 3 is a view of the helmet viewed from the back, and FIG. 4 is an enlarged cross-sectional view of a light emitting unit.
