SUMMARY OF THE INVENTION [0006] The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a helmet which is bulky and bulky to be stored and carried after use.

In order to attain the object, in a helmet including a plurality of body parts, at least two of the body parts are connected to each other by a folding connection part, and a connecting part in which a plurality of body parts are folded together by two or more hinges, And the bars are crossed with each other at the projecting end of the main body when the projecting portion of the helmet is opened by the connecting portion, thereby preventing the departure of the intersection.

In the present invention, the folded body portion of the folded body is intersected with the depressed portion and the protruded portion of the different body portions, thereby reducing the volume of the helmet and facilitating storage and carrying.

The present invention relates to a foldable helmet. Here, the folding helmet is a foldable helmet that makes it easy to move by reducing the volume and making it easy to carry.

The process of collapsing the helmet according to the present invention is shown in the order of FIGS. 1, 3, and 5.

1 is a perspective view of a folding helmet as viewed from the outside.

The first body part 1 and the second body part 2 are connected to each other by the connecting parts 7 and 8 in the form of a helmet.

The plurality of connecting portions 7 and 8 serve to connect the first body portion 1 and the second body portion 2 with each other, The first main body portion 1 and the second main body portion 2 are folded over each other with the connecting portions 7 and 8 as a center.

The main body 1 and the second main body 2 protect the periphery of the back of the head while the first and second main bodies 1 and 2 protect the periphery of the forehead.

The main body part (1, 2) is connected by the connecting parts (7, 8) to form a rounded rim that can be worn on the head. The protruding parts And depressed portions 5 and 6 are formed.

The order of installation of the projections 3 and 4 and the depressions 5 and 6 of the main body 1 and 2 is in the order of the depressions 3 and 4, the projections 3 and 4, and the depressions 5 and 6 .

The protrusions (3, 4) serve to protect the head in a semi-circular shape.

Between the protrusions 3, 4 there are depressions 5, 6, which serve as vents for empty spaces.

The protrusions 3, 4 and the depressions 5, 6 are the same in size so that the first protrusions 3 can be cross-inserted into the second depressions 6.

The connecting portions 7 and 8 have a first connecting portion 7 attached to the end of the first main body portion 1 and a second connecting portion 8 attached to the end of the second main body portion 2.

As shown in FIG. 2, the depressions 5 and 6 formed on the upper side of the main body 1 and 2 and the protrusions 3 and 4 as a whole are hemispherical.

The first bar (9) is attached to the end of the first projection (3).

The second bar (10) is attached to the end of the second projection (4).

The first projection 3 is projected to the second depression 6 or the second projection 5 is projected to the first depression 6 at the thickness and width depth of the sum of the first bar 9 and the second bar 10, 4).

Due to the first bar 9 and the second bar 10,

The first protrusion 3 prevents the second depression 6 from deviating from the point where the second protrusion 4 intersects the first depression 5. [

Fig. 3 shows a process of folding in the helmet shape of Fig. 1 due to the connection portions 7, 8.

In the crossing means as the folding process, the first projection 3 and the second depression 6 intersect with each other to form different intersections at an angle shifted diagonally as the crossing progresses.

The point of intersection is a point where the protrusions 3 and 4 and the depressions 5 and 6 meet, and at the end of each of the protrusions 3 and 4 and the depressions 5 and 6 in the process of folding the helmet, , 2).

The connecting portions (7, 8) are perforated in the center of a flat conical column and are installed standing on both ends of the body portions (1, 2).

The connecting portions 7 and 8 are formed such that the flat surfaces of the first connecting portion 7 and the second connecting portion 8 are connected and the pins 11 are inserted in the middle, As a hinge.

Fig. 4 is a view from inside of the helmet folding process.

The first bar 9 and the second bar 10 attached to each other in FIG. 2 are separated from each other in the process of folding the helmet.

Fig. 5 shows a state in which the helmet is folded.

The first and second main body portions 1 and 2 can be brought into contact with each other by the connection portions 7 and 8 connected to each other.

The size of the fully collapsed state is reduced by about half the size of the helmet condition.

6 shows a folded state of the helmet seen from the inside.

The binding apparatus 12 is installed in order to prevent the wearer from deforming from the shape of Fig. 1 to the shape of Fig. 4 to Fig. 6 without the wearer's intention.

The binding device 12 is installed between the first bar 9 and the second bar 10 when the present invention is in a helmet state, and prevents the first bar 9 and the second bar 10 from being separated.

When the present invention is used as a helmet state, an undesirable folding situation may occur due to the influence of the outside.

In order to prevent such a situation, it is necessary to prevent the bars 9 and 10 from being separated from each other.

The binding device 12 provides a binding force to prevent the bars from falling apart.

The binding device 12 can be a hook, a clip, an adhesive, a bolt, a squeak, a string, or other means.
