Helmets are always available as disaster prevention tools in schools and companies, even in factories that are not always used. It is usually a semi-circular shape that fits the human head and is large. Because of its shape, it gets in the way if it is placed in a familiar place such as on a desk. It is often placed in a warehouse, etc., but if it is placed in a warehouse, etc., there is a problem that it cannot be worn immediately when needed, such as in a disaster.
In some patent documents, a dividing mechanism and a folding mechanism make it small and easy to store, which saves space and solves the problem of storage. It takes time to assemble, but many of them are easy to understand and can be done in a short time. However, such a helmet has a split mechanism and a folding mechanism, but also secures the strength as a helmet, so that it tends to have a complicated structure and is more expensive than a conventional helmet. In addition, although it can be made into a form that is easier to store than a conventional helmet, it does not have a perfect plate shape, so there still remains a problem during storage.
In summary, conventional helmets have the problem of requiring a large space for storage, and helmets with a split mechanism and folding mechanism according to numerous patent documents solve some storage problems with that mechanism. Is not enough, and the cost tends to be high.

Since the helmet of the present invention has a perfect plate shape when stored, it can be placed in a drawer of a desk. It is also possible to stack and store in large quantities, and there is little trouble with the storage location. It is easy to assemble and anyone can change from a plate to a helmet. The protection ability is the same as a normal helmet, it has a double structure of a cap body and a hammock, and it can firmly protect the head. The price is basically composed of two plate-shaped substances and removable parts such as wire fasteners, which is inexpensive. It has all the conditions to be popular at home, school, workplace, etc. In addition, if necessary, a headband, a chin strap, or the like can be attached and used in the same manner as other helmets.

According to the present invention, a plate-shaped substance is fixed in a bent state and used as a helmet. Using the force to return when the plate-shaped material is bent and the restoring force due to elasticity, both the cap body that absorbs the impact on the outside of the helmet and the hammock that wraps and protects the head on the inside are constructed, and the restoration by the elasticity. The force is also useful for absorbing shock from the outside. When used as a helmet, the plate-shaped substance is bent and used, but when not in use, it can be made into a plate-like shape, so it can be made compact when stored. A helmet or hood, safety cap, or hat that saves space, is inexpensive, and can ensure high safety.

The present invention comprises three points: a cap body part (1) that becomes the outer side when it becomes a helmet type, a hammock part (2) that becomes the inner side and comes into contact with the head, and a detachable part (3) such as a wire fastener. However, if necessary, like other helmets, a headband for fixing the head and a chin strap for keeping the helmet on the head can be joined to the helmet of the present invention for use.

The cap body part (1) uses a substance such as resin, cardboard, metal, etc., which has a force to return when bent and a restoring force due to elasticity. Soft cloths that are not elastic are not suitable for use. It is a tough substance that is flexible, can be bent manually, and does not crack or break even when bent, and uses a substance that has the power to return to its original state and the restoring force when bent. The restoring force of this substance also helps absorb shocks and protects the head as it is. A substance that is strong against impact and a substance that can absorb impact are preferable.

The hammock part (2) is made of cloth, resin, paper, metal, or the like, and is a substance that is flexible to some extent and can withstand the force pulled by the restoring force of the cap body part (1). Since it touches the head directly, it is safe to touch the skin, and a soft substance is preferable. And, like the cap body part (1), a substance that is strong against impact and a substance that can absorb impact are preferable.

As the detachable part (3) such as a wire fastener, a wire fastener, a hook-and-loop fastener, a button and a buttonhole attachment, a bolt and a nut, a male and female fastener, and other objects that can be attached and detached are used. Further, when this is closed, the cap body part (1) can be used as a bending helmet, and when opened, it returns to a plate shape and becomes a shape suitable for storage.

When the detachable part (3) is closed, the cap body part (1) bends and is pulled outward by the restoring force of the cap body part (1), so a substance that can withstand the force is used. And a substance that can withstand the impact of the helmet is preferable. Further, the method of joining the detachable part (3) to the hammock part (2) or the cap body part (1) may be any method such as stitching, welding, adhesion, etc., but the force pulled by the restoring force of the cap body part (1). Use a joining method that can withstand.

The cap body part (1) and the hammock part (2) are joined to each other at two or more points, and this is a detachable part such as a wire fastener without directly joining the cap body part (1) and the hammock part (2). It may be joined via (3). Since it is joined at two or more points, pulling either the cap body part (1) or the hammock part (2) between the jointed parts will pull the other as well. The two points are spaced apart to some extent, and normally the ends of the cap body part (1) and the hammock part (2) are joined to each other, but the cap body part (1) is sufficiently bent so that it can be used as a helmet. If possible, it does not have to be the edge. Then, the detachable part (3) such as the wire fastener is joined to the cap body part (1) and the hammock part (2) between the two points, and is normally in an open state, and when closed, the cap body part. When the (1) and the hammock part (2) are pulled inward and opened, the pulling force disappears, and no force is exerted on the cap body part (1) and the hammock part (2).

When the detachable part (3) is closed, the cap body part (1) is bent to form a helmet type, but if the detachable part (3) is attached to the hammock part (2) side, the hammock part (2) shrinks. , The cap body part (1) bends in an inverted U shape by being pulled by the hammock part (2). At this time, the hammock part (2) is usually in a taut state, but depending on the characteristics, shape, and mounting method of the cap body part (1), hammock part (2), and detachable part (3), the cap is partially stretched. If you make a strong part or a weak part to bend the body part (1), the cap body part (1) will bend sufficiently due to the strong part, and the hammock part (2) will not be taut in the weak part. Can be dented inward. It is a structure that creates a space to put the head in this recessed part, and if it is based on this structure, it is not necessary to follow the following embodiment.

The cap body part (1) and the hammock part (2) are not necessarily one-to-one, and either one or both may be multiplexed. By multiplexing the cap body part (1) and the hammock part (2), the impact resistance of the helmet can be increased.

If necessary, a headband that more secures the head and a chin strap that keeps the helmet from coming off the head can be used by joining to the cap body part (1) and / or the hammock part (2). As for the wire fastener in the first embodiment, in the case where the detachable part (3) is excessively exposed to the outside, the excess portion (7) can be used as a headband or a chin strap.

By using a disposable material such as thick paper for the cap body part (1) and a non-woven fabric for the hammock part (2), it is possible to make a disposable helmet.
