Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is designed to be worn by workers engaged in various live line construction works such as power transmission, substation, and distribution, as well as other general construction work, and The present invention relates to a work helmet that protects workers and at the same time allows communication between workers and between workers and a control room, etc.

(Prior Art) Helmets incorporating wireless equipment for mutual communication have been known for a long time, as shown in Japanese Patent Application Laid-Open No. 48-30809, but conventional helmets have a circuit board with the required functions. In order to store the helmet, it inevitably becomes larger and heavier, and wearing it for a long time causes significant fatigue and reduces work efficiency. Furthermore, as shown in the above publication, the helmet in which the control circuit storage part protrudes from the lower surface of the cap body cannot buffer the impact when the top of the head is hit, and the original function of the helmet is not satisfied. Not only is it not possible to remove the control circuit and other electronic functional parts during repairs, the entire helmet must be disassembled, and a specially shaped helmet cap body must be manufactured. However, there were drawbacks such as high manufacturing costs.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned conventional problems, provides less fatigue even when worn for a long time, provides excellent head protection against impact, and provides electronic functional components. It was developed with the aim of creating a work helmet that was easy to replace and inexpensive to manufacture.

(Means for Solving the Problems) The present invention is characterized in that the cushioning body provided on the inner surface of the helmet cap body is sufficiently thickened to form recesses on the top and side surfaces of the head, and the cushioning body is A curved parts mounting plate with a parts storage part shaped corresponding to the recessed part is provided between the above-mentioned recessed part and the helmet cap body.
This is characterized by the fact that it is installed with batteries etc.

(Example) Next, the present invention will be described in more detail with reference to the drawings.
In Figure 1, (1) is a helmet cap made of fiber-reinforced plastics, polyethylene, polycarbonate, etc., and (2) is a hammock for fixing the helmet to the head. is provided with a buffer body (3) made of a material with excellent shock absorption performance, such as styrofoam resin. The thickness of this cushioning body (3) shall be sufficiently thick at the top of the head, approximately 30 to 50 mm, in order to pass the legal shock absorption test. Recesses (4) and (5) as shown in the figure are formed on the top of the head and the upper surface of the left and right temporal regions of the buffer (3). The depth of these recesses (4) and (5) is the same as that of the bottom buffer (3).
The thickness is determined to be at least about 101). (6) is a curved component mounting plate attached between the helmet cap body (1) and the buffer body (3). This component mounting plate (6) is made of a synthetic resin plate with a thickness of about 1), and includes a component storage part (7) with a shape corresponding to the recesses (4) and (5) of the above-mentioned buffer body (3). In addition to (8), the entirety of the component mounting plate (6), which is equipped with lead wires (9) and a small storage area (1) for storing the microphone Ql, is shaped like the inner surface of the helmet cap body (1). Although it has a curved surface that follows the curve, parts that do not need to support parts or lead wires are cut out as shown in the figure to reduce weight. Electronic functional components for communication (12) mounted on the board are set in the component storage area (7) at the top of the head of the component mounting plate (6), and the component storage area (8) at the side of the head is set. ) has a battery (1
3) is inserted into the forehead bone, and a narrow directional microphone Oal is also inserted into the forehead bone via a lead wire (9).

Furthermore, the lead wire (9) to the receiver (15) set in the earmuff (14) and the lead wire (9) to the antenna (18) attached to the component mounting plate (6) above it. Antenna (18) attached to the upper component mounting plate (6)
(91 is also set in the parts mounting plate (6) in advance, and the parts mounting plate (6) is installed between the helmet cap body (1) and the buffer body (3). Generally, studs (16) for fixing the hammock (2) are provided on the inner surface of the helmet cap body ill, and the above-mentioned component mounting plate (6) uses these studs (16) to attach the helmet to the helmet. It is attached to the helmet body (1).The ear flaps (14) are also attached by inserting the bifurcated bracket (17) at the upper end into the lower end of the helmet body (1), and then using these studs (16). If these parts are attached using the rivets (16) of the helmet cap body (1) in this way, a commercially available helmet cap body can be used as is, reducing manufacturing costs. can do.

Although radio waves are normally used as a communication medium, infrared rays and visible light can also be used when used inside specific buildings. In either case, electronic functional components ( In addition to the communication circuit, 12) is preferably equipped with a position display circuit that emits a signal (No. 3) to indicate the worker's current location.This allows the worker's current location to be constantly monitored in the control room, etc. In the event of an emergency, it is also possible to instruct each worker on the optimal evacuation route through the telephone line.

(Function) Items constructed in this way can be worn by workers engaged in various types of live wire construction work and general construction work to protect the workers' heads, as well as between workers and between workers and control rooms, etc. In the present invention, a recess (4) is provided on the upper surface of a sufficiently thickened buffer body (3).
(5), and electronic functional components (12), batteries (13), etc. are set on a component mounting plate (6) that has component storage sections (7) and (8) of corresponding shapes. Then, the parts storage areas (
7) and (8), the thick cushioning body (3) absorbs the shock even if a shock is applied to the head, and it also protects the electronic functional parts (12) and batteries (13). Since the parts mounting plate (6) and the buffer body (3) are interposed between the worker's head and the worker's head, these protrusions will not hit the head, resulting in excellent safety. Become.

In addition, by removing the component mounting plate (6) from the helmet body (1), the electronic functional component (12), battery (13), etc. can be taken out as one unit, making repairs and battery replacement easier. Since the helmet cap body (1) also serves as a lid for these parts, an increase in weight can be suppressed.

In addition, as in the embodiment, the production cost is low because the component mounting plate (6) is fixed using the rivets (16) because the ready-made helmet cap body can be used as is.
Since there is no need to add additional mounting parts, there are advantages such as suppressing weight increase. In addition, if the microphone Ql has narrow directivity and is embedded inside the buffer body (3), external noise is less likely to enter, and there is no trouble when wearing it, and it is also excellent in safety. Furthermore, the antenna (1
Similarly, if 8) is built-in, the antenna will not be exposed to the outside, so it will have excellent electrical insulation.
Ideal for live wire work.

(Effects of the Invention) As is clear from the above description, the present invention suppresses weight increase, reduces fatigue, provides excellent head protection, allows easy removal of electronic functional parts, and reduces manufacturing costs. It has many advantages such as being inexpensive. Therefore, the present invention eliminates the problems of conventional work helmets of this type and greatly contributes to the development of industry.
