A sliding belt 4 is placed in such a manner as to slidably contact with the inner side face of the front body 1 and the outer side face of the rear body 2. An angle-adjusting tool 5 to adjust the tilting angle of the bodies is formed around the connection shaft 3. The gap between the bodies 1 and 2 is sealed with an elastic belt 6 extending between the connection shafts 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding helmet which is convenient to carry.

[0002]

2. Description of the Related Art Foldable helmets are actually
The helmets described in Japanese Patent No. 75 and Japanese Utility Model Publication No. 56-55213 are known. In each of these helmets, a helmet member that is divided into three or more parts and is formed so as to be superposed is developed in the front and rear to form a helmet.

[0003]

However, such a conventional folding helmet has a problem in the overlapping portion of the divided members. That is, in the past,
In order to overlap the small-diameter member with the inner-diameter member of the large-diameter member, the developing position of each member is fixed by a fixing screw on the side surface of the helmet that bundles these members. Therefore, looseness is likely to occur in the overlapping portion of each member. In addition, each polymerized portion is likely to come off, leaving a problem in impact resistance.

Moreover, since the respective members are fixed by engaging the engaging portions, which are folded back to the side edges adjacent to each other, by engaging with each other, the respective engaging portions are stable. However, when fixing with this locking part not locked,
Each member will be fixed only with the fixing screws on the side of the helmet, and it will be extremely unstable. As a result, the shape of the helmet that can be used safely is limited to one, and the shape is limited depending on the purpose of use, such as a work helmet and a motorcycle helmet. Further, when the respective locking portions are in the engaged state, the entire helmet is in a hermetically sealed state, and the air permeability is extremely poor.

Therefore, the present invention was created in order to solve the above-mentioned problems, and is excellent in impact resistance, has good breathability, prevents rattling, and can be used in various shapes according to the purpose of use. The purpose is to provide a folding helmet that can

SUMMARY OF THE INVENTION In order to achieve the above object, according to the present invention, a front body 1 covering a front head and a rear body 2 covering a back head are swingably connected by a connecting shaft 3 on a side surface. It is a folding helmet that has an inner surface of a front body 1 and a rear body 2.
The slidable contact strips 4 that are in contact with the outer side surfaces of the strips are arranged. An angle adjusting tool 5 for adjusting the swing angle of each face piece is provided around the connecting shaft 3. Further, providing an elastic belt 6 for covering the gap between the face bodies 1 and 2 between the connecting shafts 3 is a means for solving the problem.

[0007]

That is, according to the present invention, the front body 1 and the rear body 2 are
And swing back and forth around the connecting shaft 3 as a fulcrum. Sliding band 4
Prevents backlash between the face bodies 1 and 2 and forms a ventilation gap between the face bodies 1 and 2. Angle adjustment tool 5
Fixes the angle between the front body 1 and the rear body 2. The elastic belt 6 covers the gap between the face bodies 1 and 2 formed by the sliding contact belt body 4 and prevents rainwater from entering.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 shown in the drawings is a front body that covers the front head, and the front body 1 is connected to a front and rear swingable front and rear by a connecting shaft 3 together with a rear body 2 that also covers the back head. Further, the sliding contact band body 4 is provided on the inner side surface of the front body 1 and the outer side surface of the rear body 2. The sliding contact strips 4 are in contact with each other and form a gap between the face bodies 1 and 2 and fix the overlapping position of the face bodies 1 and 2. The sliding contact strip 4 in the illustrated example is provided at the top position of each of the face bodies 1 and 2.

The angle adjuster 5 is mounted around the connecting shaft 3 to fix the swing angle of each of the face bodies 1 and 2. The illustrated angle adjusting tool 5 includes a slide rod 5A provided on the inner side surface of the front body 1 and a plurality of locking groove portions 5B radially provided around the connecting shaft 3 on the upper surface of the rear body 2. Then, when adjusting the angle, the slide rod 5A is inserted and fixed in the locking groove portion 5B selected at an arbitrary position (see FIGS. 1 and 5). At this time, the reinforcing portion 1A having a thick wall is formed on the inner surface of the front body 1, and the sliding groove portion 1B on which the slide rod 5A slides is provided on the reinforcing portion 1A, whereby the structure of the angle adjusting tool 5 is strengthened. Can be achieved (see FIGS. 3 and 6). In addition, the reference numeral 7 shown in FIG. 5 is a spout projectingly provided on the rear face body 2,
This spur 7 is locked to a holding body 5C for holding the slide rod 5A provided on the inner side surface of the front body 1, and the swinging angle of each of the face bodies 1 and 2 is fixed at the maximum angle.

The elastic belt 6 covers the gap between the face bodies 1 and 2 and is used in rainy weather to prevent rainwater from entering. Except when it is raining, the gap between the face bodies 1 and 2 is opened and the gap is used as a ventilation hole. Although the elastic belt 6 shown in the figure is preliminarily attached between the connecting shafts 3, it may be detachably provided and attached only when in use.

Reference numeral P in the drawing denotes an interior body mounted inside the helmet of the present invention.

[0012]

The present invention achieves the original object by having the above-mentioned configuration. That is, by disposing the sliding contact strips 4 that are in contact with each other on the inner side surface of the front body 1 and the outer side surface of the rear body 2, it is possible to provide excellent impact resistance and prevent rattling. Further, since the gap between the face bodies 1 and 2 formed by the sliding contact belt body 4 serves as a ventilation hole, it is possible to prevent stuffiness inside the helmet during sweating and provide an extremely comfortable working environment.

Further, together with the sliding contact strip 4, an angle adjusting tool 5 for adjusting the swing angle of each face piece is provided around the connecting shaft 3, so that each face piece 1, 2 is fixed at an arbitrary angle. Things are possible. As a result, it has become possible to properly use a helmet for work or a helmet for motorcycles according to the purpose of use.

Moreover, since the elastic belt 6 covering the space between the face bodies 1 and 2 is provided, it is possible to prevent rainwater from entering the helmet even in rainy weather.

As described above, according to the present invention, there are various industrially useful materials such as excellent impact resistance, good breathability, prevention of rattling, and different shapes according to the purpose of use. It is effective.
