Description

  The present invention relates to a helmet for working, driving, sports, military, disaster prevention, etc., and more specifically, a helmet capable of reducing the volume of the helmet by turning a part of the helmet when not in use. About.

As a helmet having a mechanism capable of reducing the volume of the helmet (volume reduction) when not in use, various structures such as a separable type, a flip type, and a fold type have been developed.
For example, the helmet described in Patent Document 1 is a separable helmet, and the helmet body is vertically divided into two, and the upper cap can be integrated by engaging the lower transparent protective body, In use, the cap is pressed from above to release the engagement with the transparent protective body, and the suspension body is housed in the transparent protective body with the cap suspended by the hanging body provided inside the transparent protective body. Has a structure that
Further, the helmet described in Patent Document 2 is a flip type helmet, and the helmet body is divided into two in the vertical direction, and the upper dome-like shell member is via a pivot extending in the left and right direction of the lower annular shell member. It has a structure that can be connected in an invertible manner.

Unexamined-Japanese-Patent No. 2004-084145 Patent No. 5908929 gazette

However, the helmet according to Patent Document 1 has at least one of the problems described below.
(1) Since the engagement state between the cap and the transparent protective body is released by the pressing force from the upper side, there is a problem in the protective function by the impact of a dropped object or the like.
(2) When the engagement mechanism becomes sweet, the cap is dropped, and the feeling of use is bad.
(3) When it is raining, rain is likely to be accumulated at the engagement portion between the cap and the transparent protective body, and water may leak inside the helmet through the clearance at the engagement portion.
(4) Since the cap and the transparent protective body are connected by the hanging body, if the hanging body is broken and each member is separated, it is not possible to know whereabouts of the members.

Further, the helmet according to Patent Document 2 has at least one of the problems described below.
(5) The inverted movement of the dome-like shell member is realized by sliding the pivot in the long hole to shift the relative position between the dome-like shell member and the annular shell member, so that the impact of dropped objects etc. There is a possibility that the dome-shaped shell member may slide and turn over due to the pressing force from above, and in non-inverted state, locking means for positioning the dome-shaped shell member is essential.
(6) In order to shift the relative position between the dome-like shell member and the annular shell member, it is necessary to flatten the contact surface between the dome-like shell member and the annular shell member. Water easily leaks inside the helmet through the gap between the member and the annular shell member.
(7) Since the reversing operation of the dome-like shell member is realized by shifting the relative position of the dome-like shell member and the annular shell member, it is generated by forward and backward rocking of the dome-like shell member in the non-reversal state In order to avoid water leakage from the gap, the lock means shown in the above (5) is essential.

  As described above, it is an object of the present invention to provide a more convenient and safe helmet in a helmet whose volume can be reduced.

The first invention of the present application made to solve the above problems is a pivoting helmet, which comprises a base and a movable part formed by dividing a helmet main body into upper and lower parts in parallel with the horizontal direction as the rotation axis direction. At least a pivoting portion, the first rotating shaft being connected to the movable portion, and the second rotating shaft being connected to the base The movable part is rotated with the pivoting part so that part or all of the movable part can be accommodated inside the base from the lower side of the base with the top of the movable part facing upward. It features.
Further, according to a second invention of the present application, in the first invention, a step having an outer peripheral side as a recess is provided in an upper portion of the base, and a lower edge of the movable portion is fitted to the recess to make the base and the movable portion It is characterized by connecting.

According to the present invention, at least any one of the effects described below is provided.
(1) The outer surface of the helmet can be made continuous.
The vertical relationship between the base and the movable part can be exchanged by the pivoting part interposed between the base and the movable part.
Therefore, the continuity of the outer surface of the helmet, which could not be realized without the separate type helmet where the base and the movable part are completely independent, can be realized.
If the continuity of the outer surface of the helmet can be secured, no step or large gap will be generated on the outer surface at the connection portion between the base and the movable portion in the use state.
(2) It is difficult to flood water from the gap between the base and the movable part.
Since the connecting surface which becomes a gap between the base and the movable portion includes a substantially horizontal surface, water hardly enters the gap when the helmet is used.
(3) It is possible to suppress the possibility of flooding inside the helmet.
The stepped surface provided at the base prevents the interior of the helmet from being flooded.
(4) The movable part can be prevented from sinking.
Since the convex portion provided on the base is sandwiched between the lower edge of the movable portion and the overhang portion, the movable portion does not open and sink downward under a pressing force from above.
