Description

  The present invention relates to a helmet including a hard shell for covering and protecting a wearer's head.

  The shell included in the helmet is formed of a hard material to protect the wearer's head. For this reason, when carrying a helmet, it was very bulky, and also when storing a helmet when not in use, a large storage space was required.

  Therefore, conventionally, the shell body is composed of a plurality of members that can be separated into a plurality of layers in the vertical direction, and the members of each layer separated when not in use are separated into a larger lower layer member of an upper layer smaller than that. There has been proposed a helmet that can be folded and compacted so as to accommodate a member (see Patent Document 1).

JP 2000-192320 A

  However, when the helmet shell is made compact when separated into a plurality of members, it is necessary to perform an operation of accommodating other members in the member while checking the size of each member separated from each other. Therefore, there is an inconvenience that cannot be made compact quickly. Moreover, when assembling the shell from the folded state to the worn state, there is an inconvenience that it is troublesome to join each member and cannot be worn quickly.

  In view of the above inconveniences, an object of the present invention is to provide a helmet that can not only make the shell compact when not in use, but can also perform assembly work at the time of wearing extremely quickly.

In order to achieve such an object, the present invention includes a hard shell that covers a wearer's head, and the shell includes a dome-shaped shell member that covers an upper portion of the wearer's head, and the wearer's head. An annular shell member that covers the entire circumference of the side portion of the portion, the dome-shaped shell member is connected to the annular shell member in a reversible manner through a pivot on an axis extending in the left-right direction, and the annular shell member is In the helmet that houses the dome-shaped shell member in an inverted posture inside, the annular shell member has a lower end of the dome-shaped shell member in a non-inverted posture at both the front end portion and the rear end portion of the annular shell member. And a contact portion for maintaining the non-inverted posture of the dome-shaped shell member by releasably contacting the portion.

  According to the present invention, the dome-shaped shell member in an inverted posture is accommodated inside the annular shell member simply by reversing the dome-shaped shell member around the pivot axis. The height of the body can be shortened, and the body can be easily made compact. In addition, the dome-shaped shell member housed inside the annular shell member can be returned to its original non-inverted state simply by rotating around the pivot, so that the folded shell can be worn very quickly. Can be assembled to the state.

In the present invention, the dome-shaped shell member is movable in a direction perpendicular to the reversal axis of the dome-shaped shell member by the pivot, and both contact portions of the annular shell member are the dome-shaped members. When the shell member is moved to one side in the front-rear direction orthogonal to the reversal axis, the reversal of the dome-shaped shell member is regulated by contacting the lower edge of the dome-shaped shell member, and the annular shell member The one abutting portion is released from the abutting to the lower edge of the dome-shaped shell member when the dome-shaped shell member is moved to the other side in the front-rear direction orthogonal to the reversal axis. It characterized that you permit inversion of the domed shell member.

  According to this, the state where the reversal of the dome-shaped shell member is restricted by the contact portion of the annular shell member and the reversal of the dome-shaped shell member is allowed only by moving the reversal axis of the dome-shaped shell member Can be easily switched by a simple operation.

In the present invention, when the dome-shaped shell member is in a non-inverted posture, the dome-shaped shell member has locking means for releasably locking the dome-shaped shell member with respect to the annular shell member, and the locking means includes the annular shell A locking member provided on the rear side of the member is provided, and the locking member includes a contact portion of the rear end portion among the contact portions of the front end portion and the rear end portion .

  By providing the locking means, it is possible to prevent inadvertent reversal of the dome-shaped shell member with respect to the annular shell member, and the shell body is assembled so that the shell body can be worn with the non-reversed dome-shaped shell member and the annular shell member Can be reliably maintained.

The side view of the helmet which is one Embodiment of this invention. Side surface sectional drawing of a shell. Front sectional drawing of a shell. Side surface sectional drawing of the shell which the dome-shaped shell member was in the reverse posture. Explanatory drawing of inversion operation. Side surface sectional drawing which shows the helmet of the form which provided the locking means.

  An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the helmet of this embodiment includes a shell 1 made of a hard synthetic resin material. Although not shown, a wearing body such as a hammock or a headband can be provided inside the shell 1.

  As shown in FIGS. 1 and 2, the shell 1 is composed of two members, a dome-shaped shell member 2 and an annular shell member 3. The dome-shaped shell member 2 is formed in a shape that covers the upper part of the wearer's head in a dome shape, and the annular shell member 3 is located at the lower part of the dome-shaped shell member 2 and covers the entire side of the wearer's head. It is formed in a covering shape.

  Further, as shown in FIGS. 2 and 3, the lower edge outer diameter, which is the maximum outer diameter of the dome-shaped shell member 2, is slightly smaller than the upper edge outer diameter, which is the minimum outer shape of the annular shell member 3. Yes.

  The dome-shaped shell member 2 is connected to the upper portion of the annular shell member 3 via the pivot 4. As shown in FIG. 3, the pivot 4 protrudes from the outer surface of the dome-shaped shell member 2, and is provided on the same axis at positions facing the left and right sides of the dome-shaped shell member 2.

  As shown in FIGS. 1 and 3, the annular shell member 3 is formed with a shaft hole 5 serving as a bearing for the pivot 4. The shaft hole 5 is formed in a long hole shape extending in the front-rear direction, and the pivot 4 can be moved in the front-rear direction by a guide along the longitudinal direction of the shaft hole 5.

  Although not shown, the pivot 4 can be provided not on the dome-shaped shell member 2 but on the inner surface of the annular shell member 3. In this case, the shaft hole 5 may be provided in the dome-shaped shell member 2. In the present embodiment, the pivot 4 is protruded from the outer surface of the dome-shaped shell member 2, so that the pivot 4 is not exposed to the inside of the shell 1 and does not obstruct the wearing body or the wearer.

  Although the dome-shaped shell member 2 and the annular shell member 3 are not separable by the pivot 4, the dome-shaped shell member 2 is rotatable around the pivot 4. And the dome-shaped shell member 2 can be made into an inversion attitude | position with respect to the cyclic | annular shell member 3, as shown in FIG. Regarding the state of the dome-shaped shell member 2, in the following description, the state that is exposed above the annular shell member 3 and can be worn is called a non-inverted posture. The state accommodated inside the shell member 3 is referred to as an inverted posture.

  The axis of the pivot 4 is the reverse axis of the dome-shaped shell member 2. Since the pivot shaft 4 is movable in the front-rear direction along the shaft hole 5, the dome-shaped shell member 2 is movable in the front-rear direction within a range corresponding to the length of the shaft hole 5 with respect to the annular shell member 3. It has become. That is, the dome-shaped shell member 2 is movable in a direction (front-rear direction) orthogonal to the reversal axis along with the reversal axis.

  The annular shell member 3 is formed to have a size that can accommodate the inverted dome-shaped shell member 2. In this case, you may set the magnitude | size of the dome-shaped shell member 2 to the magnitude | size accommodated in the inside of the cyclic | annular shell member 3 in the inversion attitude | position.

  Further, as shown in FIG. 2, a front protrusion 6 that protrudes toward the inside of the annular shell member 3 is formed at the upper end of the annular shell member 3 on the front side. Similarly, a rear protrusion 7 that protrudes toward the inside of the annular shell member 3 is formed at the upper end of the annular shell member 3 on the rear side.

  When the dome-shaped shell member 2 is in the non-inverted posture, when the pivot 4 of the dome-shaped shell member 2 is located at the rear end of the shaft hole 5 of the annular shell member 3 (the state shown in FIG. 2), the lower edge of the dome-shaped shell member 2 Is in contact with both the upper surface of the front protrusion 6 and the upper surface of the rear protrusion 7 of the annular shell member 3. Thereby, the inversion of the dome-shaped shell member 2 is restricted and the non-inverted posture is maintained.

  When the dome-shaped shell member 2 in the non-inverted posture is horizontally moved forward, the pivot 4 of the dome-shaped shell member 2 is moved to the front end of the shaft hole 5 of the annular shell member 3 accordingly. This state corresponds to when the dome-shaped shell member 2 is moved to the other side (front side) orthogonal to the reverse axis in the present invention.

When the pivot 4 of the dome-shaped shell member 2 is positioned at the front end of the shaft hole 5 of the annular shell member 3, the rear lower edge of the dome-shaped shell member 2 is displaced inward as shown in FIG. The contact of the protrusion 7 with the upper surface is released. As a result, the dome-shaped shell member 2 is allowed to be reversed, and can be freely reversed as indicated by a virtual line in FIG .

  When the dome-shaped shell member 2 is inverted with respect to the annular shell member 3 in this state, the inverted dome-shaped shell member 2 is accommodated inside the annular shell member 3, and the height of the shell body 1 is Shortened and made compact. Thus, according to the present embodiment, the shell 1 can be made compact by an extremely simple operation when the helmet is not used.

  When the dome-shaped shell member 2 in the inverted posture housed inside the annular shell member 3 is returned to the non-inverted posture and the dome-shaped shell member 2 is horizontally moved rearward, the lower edge of the dome-shaped shell member 2 Is brought into contact with both the upper surface of the front projection 6 and the upper surface of the rear projection 7 of the annular shell member 3 to maintain the non-inverted posture and become a wearable state.

In the present embodiment, when the dome-shaped shell member 2 is moved rearward, the lower edges of the dome-shaped shell member 2 are positioned on the upper surface of the front projection 6 and the upper surface of the rear projection 7 of the annular shell member 3. When the dome-shaped shell member 2 is moved forward, the contact of the dome-shaped shell member 2 with the rear protrusion 7 at the rear lower edge is released. Thus, the configuration in which the dome-shaped shell member 2 is reversible is shown. However, the present invention is not limited to this, and conversely, when the dome-shaped shell member 2 is moved forward, the lower edge of the dome-shaped shell member 2 becomes the upper surface and the rear surface of the front protrusion 6 of the annular shell member 3. The reverse operation of the dome-shaped shell member 2 is restricted by coming into contact with both the upper surface of the side protrusion 7, and when the dome-shaped shell member 2 is moved backward, the front-side protrusion 6 at the lower front edge of the dome-shaped shell member 2. You may comprise so that contact | abutting to may be cancelled | released and the dome-shaped shell member 2 may become reversible .

  As described above, according to the present embodiment, the state in which the reversal of the dome-shaped shell member 2 is restricted with respect to the annular shell member 3 only by moving the reversal axis of the dome-shaped shell member 2, and the dome-shaped shell It can be switched to a state in which the reversal of the member 2 is allowed. Moreover, when the dome-shaped shell member 2 is in the non-inverted posture, the lower edge of the dome-shaped shell member 2 contacts both the upper surface of the front protrusion 6 and the upper surface of the rear protrusion 7 of the annular shell member 3. In addition, the occurrence of a gap between the non-inverted dome-shaped shell member 2 and the annular shell member 3 can be extremely reduced, and a sense of unity between the dome-shaped shell member 2 and the annular shell member 3 can be obtained. .

  In the present embodiment, as a preferred example, the shaft hole 5 of the annular shell member 3 has a long hole shape and the front protrusion 6 and the rear protrusion 7 are provided. The configuration is not limited to this. For example, although not shown, the shaft hole 5 of the annular shell member 3 may not be elongated, and the dome-shaped shell member 2 may be reversed at a fixed position without moving in the front-rear direction. This configuration also prevents inadvertent reversal of the dome-shaped shell member 2 when the dome-shaped shell member 2 is worn in a non-inverted posture, and easily reverses the dome-shaped shell member 2 when not worn. be able to.

  By the way, in order to maintain the non-inverted posture of the dome-shaped shell member 2 with certainty, a locking means for releasably locking the dome-shaped shell member 2 with respect to the annular shell member 3 may be provided. Various forms are conceivable as the locking means, and an example thereof is the locking means 8 configured as shown in FIG.

  As shown in FIG. 6, the locking means 8 is configured by a locking hole 9 provided in the lower rear edge of the dome-shaped shell member 2 and a locking member 10 provided on the rear side of the annular shell member 3. ing. The locking member 10 is slidably attached to the annular shell member 3 via the swing shaft 11, and has a locking claw 12 that locks in the locking hole 9 and a finger hooking protrusion for performing a swinging operation of the locking member 10. Part 13. Further, the locking member 10 is biased in a direction in which the locking claw 12 is locked in the locking hole 9 by a biasing means (not shown).

  When the locking claw 12 of the locking member 10 is locked in the locking hole 9, the dome-shaped shell member 2 cannot be reversed with respect to the annular shell member 3 (locked state). From this state, when the finger-hanging convex portion 13 is pulled outward and the locking member 10 is slid, the locking claw 12 of the locking member 10 is detached from the locking hole 9 and the annular shell member 3 of the dome-shaped shell member 2. The lock state for is released.

  According to this, inadvertent reversal of the dome-shaped shell member 2 in the non-reversing posture can be prevented, and the dome-shaped shell member 2 can be easily reversed by swinging the locking member 10 when desired. It can be made compact.

In the present embodiment, the dome-shaped shell member 2 has a configuration in which the reversal axis extends in the left-right direction of the shell 1 and the dome-shaped shell member 2 is reversed in the front-rear direction .
