The connecting cover portion 8 above the connecting portion. According to the invention of the present invention, in the invention described in the claim 8, the end faces of the "connecting portions 8 and 5 covering the plurality of connecting portions 5 and 5 or the connecting portion cover 8 above the connecting portion" are formed so as to form the end faces. Chimeric means of fitting.

According to the invention of claim 1, the cap body 1 having a generally hemispherical shell shape is divided into two half caps along a center line passing through the center of the top of the head, and not only the two half caps that are divided, They are divided into a central shell and a plurality of peripheral shells adjacent to the central shell. Next, the zoning central shell and the peripheral shell are connected by a rotatable hinge device, and the corresponding peripheral shell and the peripheral shell of the two half-hat bodies are joined by a rotatable hinge device.

By forming the structure, the hinge structure of the central shell and the peripheral shell of each half-hat body is bent in a flat unfolding direction, and the hinge structure of the peripheral shell of the two half-cap bodies and the peripheral shell is formed toward the opposite side. The sharp angle direction "bend" folds the hemispherical shell into a flat shape.

That is, a cap body 1 having a slightly hemispherical shell shape can be folded into a state of "stacking the two halves of the unfolded body", and can be formed without being inflated during storage or carrying (meaning: the volume is too large) )shape.

The most important feature of the present invention is that the cap body 1 having a slightly semi-shell shape can be divided into a central shell and a peripheral shell while maintaining the shape of the curved surface, and can be folded and assembled. Therefore, the shape at the time of use after assembly can maintain the shape of the slightly hemispherical shell which is the most suitable for the helmet, and does not damage the shape of the helmet like the conventional folding helmet. Then, the divided central shell and the peripheral shell can realize a folded hard hat having excellent strength since a free flesh thickness (meaning material thickness) can be formed.

Therefore, it is easy to reflex the half cap having the thickness, and it is possible to realize a structure in which "the inside of the component is easily accommodated in the folded state". In the invention described in claim 2, the entire cap body 1 is composed of two half cap bodies and a coupling member 20.

Therefore, the connecting member 20 which is "the skeleton constituting the center of the cap body 1" can be made of a material different from the two half-hat bodies, for example, a material having a stronger strength, and a solid folding helmet can be realized.

Further, by changing the color or material of the joint member 20, various ingenious designs are added.

According to the invention described in claim 3, the helmet can be safely worn by providing a locking means for maintaining the hemispherical shell shape of the helmet shape.

According to the invention described in claim 4, the structure of the "the hemispherical shell locking means for maintaining the shape of the helmet" can be realized by a simple structure.

The natural cap shape of the helmet is usually a hemispherical shell shape that is slightly longer in the front and rear direction. According to the invention of claim 5, since the cap body 1 is cut in the longitudinal direction and folded, the shape of the helmet is easy to use, and the folded state can be made as small as possible. Further, the two half-caps divided by the center line passing through the center of the center of the head, although preferably presenting the symmetrical shape as possible, can be made according to the invention described in claim 5, the front portion and the rear portion. A helmet with a different shape, such as a safety helmet with a front cymbal, as a folding helmet that is "divided into a right-handed cap 2 and a left-half cap 3 that exhibit a symmetrical shape" Shi.

According to the invention of claim 6, the half-cap body having the center shell and the plurality of peripheral shells and having a hinge structure between the center shell and the peripheral shell can be integrally molded by using a synthetic resin material, so that it is easy to manufacture. The folding helmet of the present invention is provided as cheaply as possible.

According to the invention of the present invention, the connection structure and the hinge structure of the two half-hat bodies are integrally formed in the "each half-cap body molded by the synthetic resin material", so that it is not necessary to use other than the half-cap body. The joining member is easy to manufacture, and the folding helmet of the present invention can be provided as cheaply as possible.

In addition, the connection structure between the half cap body and the half cap body, more specifically, the connection structure between the corresponding peripheral shells of the two half cap bodies and the peripheral shell forms "used to perform the dovetail fitting. The connecting portion is located at the center, and the "hinge structure in which the thin portion is connected" is located on the side of the connecting portion. Therefore, when the two half-hat bodies are folded back, the joint portion can function as a spacer member having a certain thickness, so that the half-cap body having the thickness can be easily folded back, and it is possible to easily accommodate the inner-mounted parts in the folded state. Construction.

According to the invention of claim 8, the joint portion cover 8 can be used to decoratively cover the surface of the joint portion to form a good appearance. In this way, it is possible to mask "the recessed portion and the hinge structure which may be exposed due to the presence of the joint portion 5, and the upper surface of the joint portion cover 8 and the surface of the peripheral shell adjacent to the left and right sides. The uniform surface is formed, and in the state of use, the entire body of the cap forms a slightly hemispherical shell shape of the same surface (meaning: no step, uniform surface). In addition, once the joint cover 8 is made The "dimension protruding from the surface of the peripheral case" is formed, and the cross-sectional area of the joint cover 8 protruding from the surface of the helmet is also increased, and the joint cover 8 located on the center line of the helmet functions as a structural member. effect. Moreover, since the joint cover 8 is formed with another body different from the half cap body, the design of the design can be added to the design by changing the material or color of the joint cover 8.

In addition, the joint cover may be made of a material different from the two half caps, such as a material having a higher strength.

According to the invention of claim 9, the plurality of connecting portions 5 and 5 or the connecting portion covers 8 and 8 which are separated from each other are formed in a folded state, and when assembled in the use state, the adjacent portions are fitted to each other, and There will be a sway to form a true connection. Therefore, the line "being a strong skeleton" is formed on the center line of the cap body 1 by the connecting portions 5, 5 or the connecting portion cover, and the effect of "strength required as a helmet" is further improved.

Hereinafter, an embodiment of the folding helmet of the present invention will be described with reference to the drawings.

Fig. 1 is a front perspective view of the entire cap of the helmet, Fig. 2 is a rear perspective view, and Fig. 3 is a plan view showing the folding helmet of the embodiment, which is formed of a synthetic resin material and will be slightly omitted. The hemispherical shell-shaped cap 1 is divided along the center line passing through the front and rear center of the head Cut into two half caps, that is, the right half cap 2 and the left half cap 3.

The right half cap body and the left half cap body are divided at respective opposite positions: a central shell occupying a certain range from the lower end opening edge, and a plurality of peripheral shells adjacent to the central shell.

The right half cap 2 and the left half cap 3 form a symmetrical shape. As shown in Fig. 3, the right half cap body 2 is divided into: a right central shell 2a positioned at a substantially central position, facing upward from the lower opening edge, and a right upper peripheral shell 2b joined above the right central shell And a right front peripheral casing 2c connected to the front side of the center casing; and a right rear peripheral casing 2d connected to the rear of the right central casing. The right central casing 2a, the upper right peripheral casing 2b, the right front peripheral casing 2c, and the right rear peripheral casing 2d are connected by a rotatable hinge structure. The upper right peripheral shell 2b is separated from the boundary between the right front peripheral shell 2c and the right rear peripheral shell 2d to form an abuttable state.

The left half cap body 3 forms a symmetrical shape with the right half cap body 2, and the left half cap body 3 is divided into: a left central shell 3a, a left upper peripheral shell 3b, and a left rear peripheral shell 3d, a left central shell 3a, and a left upper peripheral shell. 3b, the left front peripheral case 3c, and the left rear peripheral case 3d are connected by a rotatable hinge structure, and the left upper peripheral case 3b and the left front peripheral case 3c and the left rear peripheral case 3d are separated from each other to form an abuttable state. The shape and size of the left central shell 3a, the upper left peripheral shell 3b, the left front peripheral shell 3c, and the left rear peripheral shell 3d of the left half cap body 3 are respectively opposite to the right central shell 2a and the upper right peripheral shell 2b of the right half cap body 2, The right front peripheral shell 2c and the right rear peripheral shell 2d correspond to each other.

In the illustrated embodiment, as shown in Figures 13 and 14, the central shells 2a, 3a are formed in a trapezoidal shape, and in addition to the lower end opening edge, the upper region is The three sides are formed in a straight line, and are disposed on the outer sides of the respective sides: an upper right peripheral shell 2b and a left upper peripheral shell 3b, a right front peripheral shell 2c and a left front peripheral shell 3c, a right rear peripheral shell 2d, and a left rear peripheral shell 3d. The shape of the central shell may also form a shape other than a trapezoid. That is, the shape of the central casing may be set to be slightly triangular, and the number of upper sides may be formed into two sides, and two peripheral casings may be disposed. Alternatively, the number of the upper side of the center case is set to four or more sides, and the peripheral case is disposed on the outer side of each side.

Further, the size (size) of the center case may be made smaller, and the shape of the peripheral case may be formed to approximate a sector shape. However, in consideration of the strength of the hinge structure and the bending state of a center case and a peripheral case, the size (size) of the center case is preferably formed to have a size (size) balanced with the peripheral case.

The hinge structure between the center case and the peripheral case may be a structure in which a hinge is formed by a metal hinge shaft, but the folded helmet of the illustrated embodiment is a right center case 2a and a left center case 3a. The outer peripheral portion is linearly formed, and the thin shell portions 4 and 4 are used to connect the central shells 2a and 3a to the peripheral shells 2b to 2d and 3b to 3d, respectively, to realize thin meat (meaning that the material thickness is thin). The hinged structure and the whole shape is integrated.

In the illustrated embodiment, the division between the central casing and the peripheral casing is linear. For example, the central casing and the peripheral casing may be curved, and the hinge structure may be used only at both ends of the curve. A connection is formed to be a rotatable structure.

The peripheral shell of the right half cap 2 and the left half cap 3 More specifically, the peripheral casings 2b and 3b, 2c and 3c, 2d and 3d are respectively connected by a rotatable hinge structure.

Although the outer peripheral shells of the above-mentioned peripheral shells and the outer peripheral edges of the peripheral shells can be directly connected by a pin structure, in the illustrated embodiment, it can be understood from Fig. 15 that "the mutual fitting is formed. The connecting portion 5 of the dovetail 5a and the dovetail groove 5b" is integrally formed by being connected to the peripheral shell by the thin flesh portion 6. According to this configuration, as shown in Fig. 12, the right half cap body 2 and the left half cap body 3 are rotated around the center of the thin meat portions 6, 6 on both sides of the joint portions 5, 5 to form a fold. Therefore, a certain degree of space is formed inside the folded cap body, so that the inner body (interior part) not shown in the drawing can be reasonably accommodated.

The connection between the peripheral shells 2b, 2c, 2d of the right cap body and the peripheral shells 3b, 3c, 3d of the left cap body is not detachable, but is maintained in a connected state. Therefore, in the illustrated embodiment, as shown in Fig. 12, the lower cover 7 covers the lower portion of the "connecting portion 5 for forming the dovetail fitting", and the connecting portion cover 8 is fixed to the connected state. Above the part 5. By arranging the connecting portion cover 8 above the connecting portion 5, as shown in Fig. 8, the groove-like connection "may be exposed on the upper surface of the cap body 1" can be covered by the presence of the connecting portion 5 unit. Further, by fixing the joint portions 8 and 8 to the joint portions 5 and 5, for example, the outer surface of the cap body 1 can be formed into a uniform surface.

In the illustrated embodiment, the connecting portion cover 8 is closer to each of the peripheral shells (2b, 2c, 2d) of the right cap body 2 and the peripheral shells (3b of the left cap body 3). The surface of 3c, 3d) is more prominent. In this embodiment, since the cross-sectional area of the joint portion cover 8 is inevitably increased, it contributes to an increase in the strength of the entire cap. In addition, some ingenious designs can be added by the protruding structure of the center.

a connection structure between the right half cap 2 and the left half cap 3, a connection position of the right upper peripheral case 2b and the left upper peripheral case 3b, a connection position between the right front peripheral case 2c and the left front peripheral case 3c, and a right rear peripheral case 2d. The joint positions of the left rear peripheral casing 3d respectively form independent positions. Next, in the folded state, as shown in Fig. 13, the connecting portion and the connecting portion cover 8 separate the adjacent portions, and in the assembled state used as the helmet, as shown in Figs. The connecting portion 5 and the connecting portion cover 8 are formed such that adjacent portions are brought into contact with each other.

In the case where the helmets in the assembled state shown in FIGS. 1 to 8 are folded, the hinge structure of the center case and the peripheral case of the right half cap 2 and the left half cap 3 can be used. The thin meat portions 4 and 4 are bent in a direction in which they are flattened, and the connecting portion 5 which is a "hinge structure between the right half cap body 2 and the peripheral shell of the left half cap body 3" is more specifically The thin portion 6 of the joint portion 5 is bent in an acute angle direction in which the folds are formed, and is formed in a folded state as shown in Figs.

As can be seen from Figures 9 and 13, the spacing of the joint portions 8, 8 in the folded state; the spacing between the central shell 2a and the peripheral shells 2b, 2c, 2d; the central shell 3a and the peripheral shells 2b, 2c, 2d The intervals are all expanded. In order to make the helmet in the assembled state form the folded state described above, the right half cap 2 and the left half cap 3 can be pressed from the left and right sides. The hinge structures are bent in the folding direction, and the folding is simply formed.

In order to assemble the cap body in a folded state into a hemispherical shell shape in the shape of a helmet, the cap may be assembled by pressing the helmet in the front-rear direction to urge the adjacent joint portions 5, 5 and 8, 8 to approach each other.

The plurality of connecting portions 5 and 5 are separated from each other. Therefore, for example, in the assembled state, even if they are in a state of abutting each other, it is difficult for the cap to maintain its shape, and it is difficult to maintain the strength as a helmet. Therefore, in the folding helmet of the embodiment shown in the figure, the adjacent connecting portions 5 and 5 or the connecting portion covers 8 and 8 are fitted to each other, so that the shape of the helmet can be stably maintained. More specifically, a projection 10 and a fitting hole 10 into which the projection 10 can be fitted are provided in the longitudinal end surface of the joint cover 8 which is "over the joint portion 5 and has a large cross-sectional area". In the assembled state, the projection 10 is fitted into the fitting hole 10, and a "stable connection state in which the positional deviation does not occur" is maintained.

In the illustrated embodiment, the projection 10 and the fitting hole 10 are provided on the longitudinal end surface of the coupling portion cover 8. However, the fitting means for the projection and the fitting hole may be provided in the coupling portions 5 and 5. End face. Further, the fitting means may have a fitting structure other than the projection 9 and the fitting hole 10 as shown in the embodiment.

As shown in Figs. 13 and 14, the opposite side faces of the peripheral casings 2b and 2c and the opposite side faces of the peripheral casings 2b and 2d are provided by the projections 11 and the recesses 12 which are engageable with the projections 11 The side of the peripheral casing forms a shape in which the cap 1 which is in the shape of a hemisphere can be more stably maintained.

Folding helmet, in the case of wearing as a helmet, The shape of the helmet as a cap must be maintained and there must be no accidental folding. As long as the "shape to be worn as a helmet" can be maintained, it is possible to simply form a snap by simply clicking on a click mechanism.

Having said that, when used as a helmet, it is preferable to maintain a reliable assembly state and use it with peace of mind. This problem can be solved by having a locking means for "stablely maintaining the assembled state as a helmet".

The locking means for maintaining the hemispherical shell shape in the shape of a helmet is a locking cord 13 which is "a helmet which can be used to assemble a folded state". The locking cord 13 is a member that is "connected to the peripheral shells of the right half cap 2 and the left half cap 3", and is attached to the "connecting portion 5 at one end thereof, and located at Between the other end connecting portions 5", the connecting portion 5 at one end and the connecting portion 5 at the other end are pulled together by the locking cord 13, and assembled into a shape of a helmet. Therefore, the lock structure for "maintaining the assembled state of the helmet" can be realized by locking the lock cord 13 "presenting the state in which the joint portions 5, 5 are brought closer" by the lock claws 14.

As shown in Fig. 7, the locking cord 13 is supported by a support shaft 15 provided to "connect the right rear peripheral shell 2d and the left rear peripheral shell 3d" and is attached to the "right front peripheral shell". The rewinding shaft 16 of the front connecting portion 5" of the left front peripheral casing 3c and the left front peripheral casing 3c are pulled out from the window hole 17 formed in the rear connecting portion 5 toward the accommodating portion. Accordingly, the cap in the folded state can be folded by tightening the locking cord 13 that has been pulled out of the housing portion. The body 1 is mounted in the shape of a hemispherical shell.

As shown in Fig. 7, the lock claws 14 are rotatably disposed by the shaft 18 such that a part thereof protrudes from the "connection portion 5 formed in the window hole 17" or the "hole of the joint portion cover 8". Partial position. On the outer surface of the locking claw 14, a serration 14a that "can be engaged with the surface of the locking cord 13 to form a slip-proof" is formed, and "the locking claw 18 that is engaged with the locking cord 13" can be formed without being idling. Constructed to achieve. The locking cord 13 can be released by, for example, being lifted up (raised) to release the engagement with the locking pawl 14, so that the portion that has been pulled out of the receiving portion is again fed into the recovery portion to form a foldable portion. The lock cord 13 that has been pulled out of the accommodating portion is located at the joint portion 5, more specifically, "the accommodating groove 19 formed on the outer surface of the joint portion cover 8", and the front end of the lock rope 13 is locked. In the part of the helmet, such as the inner surface of the back head, the locking cord 13 is not obstructed and is convenient to use.

Of course, the locking means is not limited to the above-described locking mechanism for configuring the locking claws 14, and a ratchet mechanism or the like which is well known to the public can be used.

When the peripheral shells (2b, 2c, 2d) of the right half cap 2 and the peripheral shells (2b, 2c, 2d) of the left half cap 3 are joined, it is not limited to the right half cap and the left half previously described. The outer peripheral portion of the peripheral shell of the cap body is connected by the connecting portions 5 and 5 which are integrally formed and used to perform the dovetail fitting. Alternatively, as shown in Fig. 17, the independent individual connecting member 20 may be used.

In the embodiment shown in Fig. 17, the connecting member 20 has a substantially trapezoidal cross section and has a length that coincides with the "outer periphery of the peripheral casing". Of course Thereafter, on the right side of the joint member 20, the upper side of the peripheral shells (2b, 2c, 2d) of the right cap body 2 is pivotally supported by the shaft 21, respectively. On the left side of the joint member 20, the upper side of the peripheral shells (3b, 3c, 3d) of the left cap body 3 is pivotally supported by the shaft 22, respectively.

That is, the peripheral shell of one of the half caps is coupled to one side of the joint member 20 by the hinge structure, and the peripheral shell of the other half cap body is joined to the other side.

As in the embodiment shown in Fig. 17, in the case where the right half cap 2 and the left half cap 3 are connected members 20 of independent members, the material thereof can be arbitrarily selected. Therefore, the connecting member 20 can be formed of a synthetic resin material having the same material as that of the half-hat body. However, the connecting member 20 can be formed of a high-strength material, and the center of the cap body 1 after the mounting functions as a skeleton passing through the front-rear direction. In addition, by using different materials, or materials with different colors, you can also add some ingenuity in design.

The hinge structure between the joint member 20 and the peripheral shell of the half-hat body can be formed by forming the shaft support by the shafts 21 and 22 having a full length in the longitudinal direction or having a certain length. In this case, the side of the connecting member 20 and the upper side of the periphery of the peripheral case are formed linearly. On the other hand, the connecting member 20 and the peripheral case can have a structure in which "the both ends in the longitudinal direction form a shaft support". In this case, the side of the connecting member 20 and the upper side of the peripheral shell of the half-hat body may be curved.

In the end surface of the connecting member 20 in the longitudinal direction, a projection and a fitting hole corresponding to the projection 9 and the fitting hole 10 of the coupling portion cover 8 in the above-described embodiment, or other engaging means can be formed. this When the engaging member 20 is engaged with the engaging hole or the engaging hole or the other engaging means, and the hemispherical shell shape is assembled as a helmet, the position of the connecting member 20 and the connecting member 20 that are adjacent to each other is not caused. The case of offset.

It is very common to install a part inside a helmet called a "hammock or cushioning material". In the folding helmet of the present invention, the built-in parts can also be installed as needed. Therefore, in the illustrated embodiment, the inner surface of the right half of the right half cap 2 and the left half cap 3 is formed with the inner component mounting rod 23 on the inner surface of the front and rear positions. ,twenty three. The built-in component mounting rod 23 of the embodiment shown in the figure is simplified in structure by being integrated with the half cap body, and the "forming portion of the inner component mounting rod 23" is formed by a thick material thickness. Ensure the necessary strength.
