(Effects of the Invention)

According to the invention as set forth in claim 1, the usual hemispherical shell-shaped mother shell 1 is divided into two half shells along the center line passing through the center of the two shells, and the two half shells themselves are divided into a central shell , And a plurality of peripheral shells adjacent to the central shell. Then, the divided central shell and peripheral shell are connected by a pivotable hinge structure, and the corresponding peripheral shells and peripheral shells of the two shells themselves are connected by a rotatable hinge structure.

By this structure, the hinge structure of the central shell and the peripheral shell of each of the half-shells themselves is bent in a direction to flatten out, and the hinges of the two shells themselves and the peripheral shells are folded in an acute angle , The hemispherical shell shape can be folded flatly.

In other words, the mother board 1, which is an approximately hemispherical shell shape, can be folded in a folded state so that the developed two half shells themselves can be folded into a shape that does not become bulky in storage or carrying.

The feature of the present invention is that the mother shell 1, which is an approximately hemispherical shell shape, can be folded and assembled by dividing the shell 1 into a central shell or a peripheral shell while maintaining the shape of the curved surface. Therefore, the shape at the time of assembled use maintains an approximately hemispherical shell shape which is optimum as a helmet, and the shape as a helmet is not damaged like a conventional folding helmet. Since the partitioned central shell or peripheral shell can be formed with a free thickness, a folding helmet having an excellent strength can be realized.

According to the invention as set forth in claim 2, the gap between the blank itself and the blank itself can be maintained by the presence of the connecting member (20) when the two blank halves themselves are folded back. Therefore, it is possible to realize a structure that is easy to fold back the thick bristles themselves and easily accommodates the built-in items and the like in the folded state. According to the invention as set forth in claim 2, the entire mother body (1) is constituted by the two half shells themselves and the connecting member (20). Therefore, it is possible to realize a rigid folding helmet by making the connecting member 20 constituting the frame beyond the center of the mother body 1 different in material from the two half-shells themselves, for example, having a larger strength.

In addition, by changing the color or the material of the connecting member 20, various kinds of design tastes can be considered.

According to the invention as set forth in claim 3, the helmet can be safely worn by providing the locking means for holding the hemispherical shell shape which is the helmet shape.

According to a fourth aspect of the present invention, a reliable locking mechanism can be realized by a simple structure with respect to the concrete structure of the locking means for holding the helmet-like hemispherical shell shape.

The natural shape of the helmet itself is generally a hemispherical shell shape that is slightly longer in the anteroposterior direction. According to the invention as set forth in claim 5, since the mother body 1 is cut in the longitudinal direction and is folded, it can be easily used as a helmet and can be compactly formed in a folded state. In addition, it is preferable that the two halves dividing along the center line passing through the centers of the two centers are as accurate as possible. However, according to the invention described in claim 5, the helmet having a different shape of the front part and the rear part, The helmet can be realized as a folding helmet which divides a helmet into a symmetrical right half half 2 itself and a left half half 3 itself.

According to the invention described in claim 6, since the half shell itself having the central shell and the plurality of peripheral shells and having the hinge structure between the central shell and the peripheral shell can be molded integrally with the synthetic resin material, And the folding helmet of the present invention can be provided as cheaply as possible.

According to the invention as set forth in claim 7, since the connecting structure and the hinge structure of the two semi-square hosepipes themselves are integrally formed in each of the half-hosepipes themselves formed by the synthetic resin material, the connecting member separate from the half- So that the folding helmet of the present invention can be provided as cheap as possible.

In addition, the connection structure of the half shell itself and the half shell itself, specifically, the connection structure of the peripheral shell and the peripheral shell corresponding to the two half shells themselves, has a connection portion for dovetail fitting at the center and a thin- The hinge structure is located. Therefore, when the two halves themselves are folded back, the connecting portion functions as a clearance member having a certain thickness, so that it is easy to fold back the thick bristles themselves, and it is possible to realize a structure that is easy to accommodate the interior products in the folding state.

According to the invention as set forth in claim 8, it is possible to make the surface of the connecting portion cosmetically covered by the connecting portion cover (8). This is because the concave portion or the hinge structure which may be exposed due to the presence of the connection portion 5 is covered and hidden, and the upper surface of the connecting portion cover 8 is flush with the surface of the peripheral shell adjacent to both the left and right sides And the entire shell may be formed in an approximately hemispherical shell shape having the same height as the shell in use. When the connecting portion cover 8 is dimensioned to protrude from the surface of the peripheral shell, the cross-sectional area of the connecting portion cover 8 protruding from the surface of the helmet becomes inevitably enlarged so that the connecting portion cover 8 positioned on the center line of the helmet As a member, the reinforcing effect is exerted. Since the connecting portion cover 9 is formed separately from the semi-covering itself, it is possible to consider a preference for the portion by changing the material or the color of the connecting portion cover 8. [

In addition, the connection cover may be formed of a material different from the two semi-caps, for example, a material of higher strength.

According to the invention as set forth in claim 9, when a plurality of connecting parts (5, 5) or connecting part covers (8, 8) which are separated from each other in a folding state are adjacent to each other at the time of assembly in use, It is certainly connected without work. Therefore, there is an effect of further enhancing the strength as a helmet by forming a line which is reinforced by the connecting portions (5, 5) or the connecting portion cover on the center line of the mother body (1).

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a folding helmet according to the present invention will be described with reference to the accompanying drawings. Fig. 1 is a front perspective view of the entire body of the helmet, Fig. 2 is a rear perspective view, and Fig. 3 is a plan view.

The folding helmet according to the embodiment of the present invention is formed by molding a synthetic resin material as a whole, and has a structure in which an approximately hemispherical shell-shaped mother body 1 is divided into two half-shells themselves, that is, a half- ) And the left half mask itself (3).

The right half shell itself and the left half shell itself are partitioned into a central shell occupying a certain range above the lower opening edge at the opposed position and a plurality of peripheral shells adjacent to the central shell.

The right half mirror itself (2) and the left half mirror itself (3) are symmetrical. As shown in Fig. 3, the right half shell itself 2 has a right central shell 2a which is substantially at the center and occupies a certain range from the bottom opening edge upward, and a right upper peripheral shell 2b A right front peripheral shell 2c continuous to the front of the center shell and a right rear peripheral shell 2d continuous to the rear of the right central shell. The right central shell 2a, the right upper peripheral shell 2b, the right front peripheral shell 2c and the right rear peripheral shell 2d are connected by a rotatable hinge structure. The boundary between the right upper peripheral shell 2b and the right front peripheral shell 2c and the right rear peripheral shell 2d are separated and brought into contact with each other.

The left half shell 3 itself is symmetrical with the right half shell itself 2 and the left half shell 3 itself is made up of a left central shell 3a, a left upper peripheral shell 3b and a left rear peripheral shell 3d And the left upper peripheral shell 3b and the left front peripheral shell 3c and the left rear peripheral shell 3d are connected by a rotatable hinge structure and the left upper peripheral shell 3b, And the boundary between the left front peripheral shell 3c and the left rear peripheral shell 3d are separated and brought into contact with each other. The shapes and sizes of the left central shell 3a, the left upper peripheral shell 3b, the left front peripheral shell 3c and the left rear peripheral shell 3d of the left half shell 3 itself are the same as those of the right half shell itself Respectively correspond to the right central shell 2a, the right upper peripheral shell 2b, the right front peripheral shell 2c, and the right rear peripheral shell 2d.

In the illustrated embodiment, as shown in Figs. 13 and 14, the center shells 2a and 3a are formed in a trapezoid, and the upper portion excluding the lower opening edge is divided into three straight sides, The left front upper peripheral shell 2b and the left upper peripheral shell 3b and the right front peripheral shell 2c and the left front peripheral shell 3c and the right rear peripheral shell 2d and the left rear peripheral shell 3d are disposed, The shape of the center shell may be a shape other than a trapezoid. That is, the shape of the central shell is substantially triangular, and the number of the upper side is set to two sides, and two peripheral shells are arranged. Alternatively, the number of upper sides of the central shell may be four or more sides, and the peripheral shells may be disposed outside the respective sides.

It is also possible to make the size of the central shell small and make the shape of the peripheral shell close to the fan shape. However, in consideration of the strength of the hinge structure and the curved state of one central shell and the peripheral shell, it is preferable that the size of the central shell be in balance with the peripheral shell.

In the folding helmet according to the embodiment of the present invention, the outer periphery of the right central shell 2a and the left central shell 3a are arranged in a straight line And the central shells 2a and 3a and the peripheral shells 2b to 2d and 3b to 3d are connected to each other by the thin portions 4 and 4 in the straight portion to realize a thin hinge structure, Are formed integrally.

In the illustrated embodiment, the central shell and the peripheral shell are arranged in a straight line. However, for example, the central shell and the peripheral shell may be divided into curved lines and connected at both ends of the curved line by a hinge structure It is possible.

The corresponding peripheral shells and peripheral shells, specifically the peripheral shells 2b and 3b, 2c and 3c, 2d and 3d, of the right half shell itself 2 and the left half shell itself 3 are connected by a rotatable hinge structure.

The corresponding peripheral shells may be connected directly to the outer peripheral sides of the peripheral shells by, for example, a hinge structure. However, in the illustrated embodiment, as understood from Fig. 15, the dovetail 5a and the dovetail A connecting portion 5 having a dovetail groove 5b is formed and the connecting portion 5 is formed integrally with the peripheral shell 6 by continuous connection with the peripheral shell. 12, the right half mirror itself 2 and the left half mirror itself 3 are rotated about the thin-walled portions 6, 6 located on both sides of the connecting portions 5, 5 Folded. As a result, a certain amount of space is formed inside the folded mother body, so that the inner body (not shown) can be positively positioned.

The connection between the peripheral shells 2b, 2c, and 2d of the right-side mother body and the peripheral shells 3b, 3c, and 3d of the left-side mother body is not made detachable but the connection state is maintained. Therefore, in the embodiment shown in Fig. 12, the lower cover 7 covers the underside of the connecting portion 5 to be Dovetail fitting, and at the same time, the connection cover 5 8 are fixed. The connecting portion cover 8 is disposed above the connecting portion 5 so that it is possible to cover the groove-like connecting portion which is likely to be exposed on the upper surface of the mother 1 by the presence of the connecting portion 5 have. Further, by fixing the connecting portion covers 8 and 8 to the connecting portions 5 and 5, for example, the outer surface of the mother body 1 can be formed to have the same height.

In the illustrated embodiment, the connection cover 8 is projected from the peripheral shells 2b, 2c, and 2d of the right mother shell 2 and the peripheral shells 3b, 3c, and 3d of the left mother shell 3 have. In this embodiment, since the cross-sectional area of the connecting portion cover 8 is inevitably large, it is effective in improving the strength of the entire frame. In addition, the protruding structure of the central portion can be considered a design taste.

The connection structure between the right half shell itself 2 and the left half shell 3 is a connecting position of the right upper peripheral shell 2b and the left upper peripheral shell 3b and a connecting position between the right front peripheral shell 2c and the left front peripheral shell 3b 3c and the connection positions of the right rear rear shell 2d and the left rear rear shell 3d. In the folding state, as shown in Fig. 13, the connecting portion and the connecting portion cover 8 are separated from each other. In the assembled state used as a helmet, as shown in Figs. 1 to 8, The adjacent ones of the covers 8 come into contact with each other.

When the helmet in the assembled state shown in Figs. 1 to 8 is folded, the center shell of each of the right half shell itself 2 and the left half shell itself (3) and the thin parts (4, 4) The connecting portion 5 which is a hinge structure between the peripheral shells of the right half piece itself 2 and the left half piece itself 3 and more specifically the thin portion 6 of the connecting portion 5 are folded in two. To the folded state shown in Figs. 9 to 13 by folding in the acute angle direction.

9 and 13, the distance between the central shell 2a and the peripheral shells 2b, 2c and 2d, the distance between the central shell 3a and the peripheral shells 2b and 2c, The intervals between the shells 2b, 2c and 2d are all widened. In order to fold the helmet in the assembled state into the folded state, the right half body 2 and the left half body 3 are pressed from the left and right sides so that the respective hinge structures can be folded in the folding direction and folded simply.

In order to assemble the parent in a folded state into a hemispherical shell shape like a helmet shape, the helmet can be compressed in the forward and backward directions so that the adjacent connecting portions 5, 5 or the connecting portion covers 8, 8 are brought close to each other and assembled into a mother body.

The plurality of connecting portions 5 and 5 are separated from each other. Therefore, for example, even in a state in which they are in contact with each other in an assembled state, it is difficult to maintain the shape as a mother and it may be difficult to maintain the strength as a helmet. Therefore, in the folding helmet according to the illustrated embodiment, the adjacent connecting portions 5 and 5 or the connecting portion covers 8 and 8 are mutually folded so that the helmet shape can be firmly maintained. Concretely, the projection 9 and the fitting hole 10 in which the projection 9 is fitted are formed on the longitudinal end surface of the connecting portion cover 8 having a large cross-sectional area covering the connecting portion 5, The projection 9 and the fitting hole 10 are fitted to each other so that a strong connection state in which the positional deviation does not occur can be maintained.

Although the protrusion 9 and the fitting hole 10 are formed in the end surface in the longitudinal direction of the connecting portion cover 8 in the illustrated embodiment, it is also possible to provide a fitting means for fitting the protrusion and the fitting hole in the end surface of the connecting portion 5 It is possible. Further, the fitting means may have a fitting structure other than the projection 9 and the fitting hole 10 as in the embodiment.

13 and 14, the projections 11 and the protrusions 11 are formed on the sides of the peripheral shells on the opposite sides of the peripheral shells 2b and 2c and on the opposite sides of the peripheral shells 2b and 2d, And the shape of the hemispherical shell-like mother body 1 can be maintained firmly in the form of a hollow.

It is necessary for the folding helmet to be maintained in a hat-shaped helmet shape without being inadvertently folded when mounted as a helmet. As long as the shape to be mounted as a helmet can be held, for example, it may be simply engaged with the punch by a clip structure.

However, in order to use it as a helmet, it is desirable to ensure that the assembled state is maintained and that it can be worn safely. This problem can be solved by providing a locking means for firmly holding the assembled state as a helmet.

The locking means for holding the hemispherical shell shape, which is a helmet shape, uses a fastening string 13 that can be used to assemble the folded helmet. The fastening cords 13 are provided at the connecting portions 5 connecting the peripheral shells of the right half shell itself 2 and the left half shell itself 3 with the connecting portions 5 located at one end and the connecting portions 5 located at the other end, And the connecting part 5 at one end and the connecting part 5 at the other end are pulled together with the fastening strap 13 to assemble in the form of a helmet. Therefore, the locking structure for maintaining the assembled state as the helmet can be realized by locking the fastening cords 13 in the state in which the connecting portions 5, 5 are pulled to each other by the locking claw 14. [

7, one end of the fastening strap 13 is supported by a support shaft 15 provided at a rear connecting portion 5 connecting the right rear rear shell 2d and the left rear peripheral shell 3d The windshield 16 provided on the front connecting portion 5 for connecting the right front peripheral shell 2c and the left front peripheral shell 3c and the window hole 17 formed in the rear connecting portion 5 It is withdrawing from the device. Therefore, by pulling out the fastening strap 13 drawn out of the apparatus, the folded mother body 1 can be assembled into a hemispherical shell-like helmet shape.

7, the locking claw 14 is rotatably disposed at a position where a part of the locking hole 14 protrudes from the window 5 of the window hole 17 or the window hole of the coupling portion cover 8 . The outer surface of the locking claw 14 is formed with a tooth 14a engaged with the surface of the fastening claw 13 to prevent slipping and a structure in which the locking claw 18 engaged with the fastening claw 13 does not revolve . The fastening cords 13 are lifted up, for example, to release engagement with the locking claws 14, and a portion drawn out of the device is pulled into the device to enable folding. The fastening cords 13 drawn out of the apparatus are placed in the accommodating grooves 19 formed on the outer surface of the connecting portion cover 8 of the connecting portion 5 and the tip of the fastening cords 13 is connected to a part of the helmet, It is convenient to lock the fastening cords 13 on the inner surface of the occiput, for example, so as not to interfere with the fastening cords 13.

Above all, the locking means is not limited to the locking mechanism by the locking claw 14 of the above structure, but may adopt a known ratchet mechanism or the like.

When the peripheral shells 2b, 2c and 2d of the right half shell itself 2 and the peripheral shells 3b, 3c and 3d of the left half shell itself 3 are connected to each other, It is also possible to use a star chain connecting member 20 as shown in Fig. 17, as well as to connect them to dovetail fitting portions 5, 5 integrally formed on the outer peripheral portion of the shell.

In the embodiment shown in Fig. 17, the connecting member 20 is formed to have a substantially trapezoidal cross-section and a length coinciding with the outer periphery of the peripheral shell. The upper sides of the peripheral shells 2b, 2c and 2d of the right side shell 2 are axially supported by the shaft 21 on the right side of the connecting member 20, respectively. The upper side of the peripheral shells 3b, 3c and 3d of the left side shell 3 is supported by a shaft 22 on the left side of the connecting member 20, respectively.

That is, the peripheral shell of one half shell itself is connected to one side of the connecting member 20, and the peripheral shell of the other half shell itself is connected to the other side by a hinge structure.

When the connecting member 20, which is a member different from the right half knife itself 2 or the left half knife itself 3, is used as in the embodiment shown in Fig. 17, the material thereof can be arbitrarily selected. For this reason, the connecting member 20 can be formed of a synthetic resin material of the same material as the half-shell itself, but it can function as a framework that passes through the center of the assembled mother body 1 formed of a high- . Also, a design taste may be considered by using materials different in color or material.

The hinge structure of the connecting member 20 and the peripheral shell of the half shell itself can be supported by the shafts 21 and 22 extending over the entire length in the longitudinal direction or having a certain length dimension. In this case, the lateral sides of the connecting member 20 and the outer peripheries of the peripheral shell are formed in a straight line. On the other hand, the connecting member 20 and the peripheral shell may be supported at both ends in the longitudinal direction. In this case, the upper side of the peripheral shell of the side surface of the connecting member 20 and the half shell itself may be curved.

In the longitudinal end surface of the connecting member 20, protrusions 9 formed on the connecting portion cover 8 and protrusions corresponding to the fitting holes 10, fitting holes, or other engaging means can be formed have. At this time, the connecting member 20, which is engaged with the projection by the fitting hole or another engaging means, does not cause the positional deviation of the adjacent connecting member 20 and the connecting member 20 when assembled as a hemispherical shell as the helmet .

In helmets, it is common to install interior items such as hammocks or cushioning materials. Also in the folding helmet according to the present invention, the interior part is mounted as required. Therefore, in the illustrated embodiment, the internal-product attaching levers 23, 23 are protrudingly formed on the inner surfaces of the front and rear two places of the center shells 2a, 3a of the right half body 2 and the left half body 3 itself have. The built-in attaching lever 23 of the illustrated embodiment is integrally formed with the half-shell itself to simplify the structure, and the formed portion of the built-in attaching lever 23 is thickened to secure the necessary strength.
