Description

    The present invention relates to a protective cap or helmet used for a construction site, a disaster site, etc., and more particularly to a helmet in which a multifunctional unit can be easily mounted, and further to a helmet equipped with the multifunctional unit. .

    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 or protective caps tend to be multifunctional to satisfy various demands while satisfying the safety of the wearer's head, and are more widely worn by the wearer beyond the purpose of protecting the head. Various ideas have been proposed to provide safety, collect information, and take corrective actions.

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 made.

    In view of the fact that these conventional methods have not yet sufficiently avoided the risk of helmet wearers and that various accidents are still reported by construction workers, various ingenuity has been proposed. And trying to improve. 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 is a problem that it is impossible to confirm whether or not each of the workers at the construction site knew all of the danger predictions, and the supervisor or the supervisor who made the danger made the worker or all the workers dangerous. 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. Along with the multi-functionality of these helmets, we found the advantage of using the multi-functional part as a unit and using it as a multi-functional unit. In order to reduce the size of the multi-function unit, various types of multi-function units are being tried according to the purpose. Therefore, there is a need for a helmet that can easily replace the various multifunctional units, and when the function as an electric cap can be achieved, the range of application is further expanded.

The inventors of the present invention provided an inner shell inside at least a part of the outer shell of the helmet, and formed a storage unit for a multi-functional unit mainly by the outer shell and the inner shell. an opening for loading and unloading of the functional unit has been closed below the helmet, the shape change of the multifunction unit and / or the housing part, the multi-function unit is detachably secured to the housing section A helmet is provided as claim 1.

The helmet according to any one of claims 8 and 9, wherein the helmet is retracted and arranged by a distance greater than 30 millimeters from the outer edge of the outer shell, is provided as claim 10.

    Since the multi-function unit attached to the helmet can be easily replaced in the present invention, the multi-function unit corresponding to each purpose of use created with the same shape and size can be easily replaced without replacing the helmet body. Yes, you can use a personal helmet and wear different functional units to suit your purpose. Furthermore, since it conforms to the standard as an electric cap, it is possible to provide a helmet that is desirable for an operator and has the effect of further expanding the purpose of use. Furthermore, although it has various effects, it will be clarified from the following description.

    As the material of the helmet according to the present invention, a normal material is used, but the transparent window is made of a material having high transparency such as acrylic resin and high hardness. The outer shell body and the inner shell body of the helmet are generally made of the same material, but of course, different materials can be used according to the purpose. Preferably, the outer shell body and the inner shell body can be firmly fixed because the adhesiveness is good when they are made of the same material. Moreover, depending on the case, it can shape | mold with one metal mold | die. The transparent window may be formed by insert molding. However, after forming the outer shell and the inner shell, a transparent resin plate having an appropriate size and thickness is welded or bonded to the outer window. The shell can be integrated by welding or bonding from the inside or the outside. In any case, when the helmet is immersed in water with the top facing down, at least the outer edge portion of the outer shell body does not enter the inside through the outer shell body so long as it does not become smaller than 30 mm above the water surface. It is configured.

    In some cases, the inner shell body is formed with the end portions substantially aligned so that the outer edge portion of the inner shell body is in the same or substantially the same plane as the plane defined by the outer edge portion of the outer shell body. There is. The inner shell is preferably extended and integrated with the inner surface of the outer shell, and forms the storage portion together with the outer shell. Further, the inner shell body and the outer shell body can be combined with another member to form the storage portion. In any case, an opening of the storage part formed by the outer edge of the inner shell and the outer edge of the outer shell is provided below the helmet. The opening is used for taking in and out the multifunctional unit. In some cases, except for an opening basically composed of an outer edge portion of the outer shell body and an outer edge portion of the inner shell body, it may be sealed, and the inside of the helmet (the housing portion of the inner shell body) Even if water is put into the outside, it can be configured so that water does not enter the storage portion. Preferably, the inner shell body has a through hole so as to be circulated with the inside of the helmet. The through hole may be singular or plural, and in the case of plural, the shape may be the same or different. Moreover, when it has a some through-hole, the one or more can be utilized for the said engaging part. The outer edge portion of the inner shell body may be configured more inward than the outer edge portion of the outer shell body, and may be preferably configured closer to the inner side of the helmet by a distance greater than 30 millimeters. However, there is an advantage that the through hole can be omitted. In this case, when the helmet is placed on a flat body in a state where the outer edge portion of the outer shell body is substantially in contact, the outer edge portion of the inner shell body floats upward by the distance. Further, the outer shell and / or the inner shell may have a radio wave blocking property as required.

    Preferably, the inner shell body is disposed around an outer edge portion of the outer shell body, and is arranged along the entire outer edge portion of the outer shell body or in front of the helmet along the outer edge portion of the outer shell body. It is formed on the head or part of the back of the head. Preferably, the upper part of the head when the helmet is worn does not have the inner shell but exists around the head, so that the weight of the multi-function unit can be dispersed on the entire head of the wearer on average. It is desirable to do so. The interior of the headband that supports the head and the hammock is provided inside the helmet in the same manner as a conventional helmet. The outer shell body, the inner shell body, and the exterior body of the multi-function unit can protect the head of the helmet wearer with total strength, so that the thickness of each can be adjusted, and in some cases, The thickness of the exterior body can be reduced, and the weight of the multifunctional unit can be reduced.

    The multi-function unit is preferably of a shape and size adapted to the storage unit, in other words, the storage unit is formed according to the shape and size of the multi-function unit. The multi-functional unit is preferably a still and / or video camera, a video and / or audio transmitter and / or receiver, a danger alarm sound generator or vibrator or LED emitter, respectively. A function including all or an appropriate combination of an LED display device, a power source, and the like indicating the operation state of the device is unitized.

    The transparent window is provided at a position where the photographing window of the photographing camera or the LED light emitter and / or the LED display device can be seen from the outside. Thereby, the necessary part of the multi-function unit stored in the storage unit can be viewed from the outside.

    When the multi-function unit is stored in the storage portion, the engagement portion is provided so that the multi-function unit does not fall when the helmet is worn. A plurality of outer shell inner walls and / or inner shell inner walls can be provided. However, the shape of the storage portion is slightly distorted compared to the multi-function unit, and the shape is changed during storage. It is also possible to adopt a method in which the shape change force and the friction force are firmly fixed. When the multifunctional unit is removed from the storage unit, the multifunctional unit can be pulled out with an instantaneous strong force, and it is preferable because the multifunctional unit can be easily taken in and out. Further, the engaging portion may be a lid that covers at least a part or the entire surface of the opening. One end of the lid is integrated with the inner shell body or the outer shell body by hinge coupling (it can be formed by extending the inner shell body or the outer shell body), and the other end is integrated with the other The multifunctional unit can be securely received by engaging the shell. Further, as described above, a part of the through hole is used as an engaging portion, and an elastic protrusion (including a non-elastic protrusion that can be put in and out) is provided on the multi-function unit to engage with the through hole. It can also be. Known means can be used as the engaging means. Further, the multi-function unit may be covered to prevent the multi-function unit from falling by a method in which a part of a protective band so-called hammock is applied to the outer shell body.

    Therefore, the multifunctional unit prepared for disaster prevention and the multifunctional unit prepared for construction are stored in the storage unit according to the purpose at the time of use. Used as Alternatively, a necessary wearer can wear the desired multifunction unit, and the multifunctional unit can be replaced when an operator changes on the way. In addition, even when a new helmet is used due to the life of the helmet, there is an advantage that the multifunctional unit can be shared.

    Personal helmets tend to be unfavorable for workers to be used by others, and tend not to prefer those for others, so while using your own helmet, The operator is glad that only the multifunctional unit can be replaced, and it is possible to prevent accidents based on emotional and psychological matters.
