Abstract
Abstract A helmet comprising a main cap body (2) and an auxiliary cap body (3) mounted on left and right opposite sidewalls of the main cap body (2). The main cap body (2) is of "open-face" construction and has a large window opening (4). The auxiliary cap body (3) is turnable between a lowered position in which it covers a lower portion of the large window opening (4), and a lifted position in which the entire large window opening is exposed. A lock mechanism (39) is provided for automatically locking the auxiliary cap body (3) to the main cap body (2) in the lowered position of the auxiliary cap body (3). Thus, when the auxiliary cap body (3) is in the lowered position the locking of the auxiliary cap body (3) to the main cap body (2) is achieved reliably and easily and the helmet is given the appearance and structural advantages of a "full-face" design.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A helmet comprising: a cap body which comprises a main cap body provided at a front surface thereof with a large window opening opened at a lower edge thereof, and an auxiliary cap body pivotally supported at left and right opposite sidewalls of the main cap body; the auxiliary cap body being turnable between a lowered position for covering a lower portion of the large window opening so as to make an upper portion of the large window opening serve as a smaller window opening, and a lifted position for opening the entire large window opening; and a lock mechanism provided between the main and auxiliary cap bodies for automatically locking the auxiliary cap body, when the auxiliary cap body is turned to the lowered position.
Claim 2
Dependent Claim
129 words
A helmet as claimed in claim 1, wherein the lock mechanism comprises a lock plate mounted on one of the main and auxiliary cap bodies, a lock pin mounted on the other of the main and auxiliary cap bodies for engaging with the lock plate at the lowered position of the auxiliary cap body, a spring means for biasing the lock pin in a direction to engage the lock plate, and a releasing element mounted on the auxiliary cap body such that the lock pin is disengaged from the lock plate against a biasing force of the spring means, the lock pin being provided with a slant for inducing the lock plate into engagement with the lock pin when the auxiliary cap body is turned toward the lowered position.
Claim 3
Dependent Claim
58 words
A helmet as claimed in claim 1 or 2, further including a shield plate pivotally carried on the auxiliary cap body for opening and closing the smaller window opening, and a click stop mechanism for retaining the shield plate at different angular positions, the shield plate being coupled to the auxiliary cap body through the click stop mechanism.
Claim 4
Dependent Claim
89 words
A helmet as claimed in any one of the preceding claims, wherein the auxiliary cap body comprises a chin covering portion curved to extend forwardly, and a pair of ear portions which extend upwardly from left and right opposite ends of the chin covering portion and are pivotally supported on the main cap body, and the lock mechanism is disposed such that the pair of ear portions can be locked on the main cap body at their end portions connected to the opposite ends of the chin cover portion.
Claim 5
Dependent Claim
164 words
A helmet as claimed in claim 1, wherein the main cap body includes a pivot detachably secured to left and right outer surfaces thereof, the auxiliary cap body having a boss retained on the pivot, and the helmet further includes: a shield plate pivotally carried on the boss inside the auxiliary cap body to open and close the small window opening; a control plate secured at one end thereof to the auxiliary cap body to clamp the shield plate between the control plate itself and the auxiliary cap body, the control plate being penetrated by the pivot; and a click stop mechanism provided between the control plate and the shield plate for retaining the shield plate at different angular positions; wherein the control plate is provided with an elasticity for flexing the control plate from a side of its other end so as to disengage the shield plate to slip off from the pivot when the pivot is detached from the main cap body.
Claim 6
Dependent Claim
119 words
A helmet as claimed in claim 1, further including: a control plate secured to an inner surface of the auxiliary cap body; and an upper limit restraining means provided between the control plate and the main cap body, the upper limit restraining means comprising a stop arm formed on the control plate and an upper limit stop member fixed on an outer surface of the main cap body; wherein the upper limit stop member is provided with a stop wall for receiving the stop arm to restrain the lifted position of the auxiliary cap body, and a crest portion over which the stop arm climbs while being resiliently deformed, immediately before the auxiliary cap body reaches the lifted position.
Claim 7
Dependent Claim
45 words
A helmet as claimed in claim 6, wherein the stop arm is in abutment against the inner surface of the auxiliary cap body so that a resilient deformation is also generated in the auxiliary cap body, when the stop arm climbs over the crest portion.
Claim 8
Dependent Claim
63 words
A helmet as claimed in claim 6 or 7, wherein the upper limit member is provided on the main cap body at a position separated radially from a position where the auxiliary cap body is pivotally carried on the main cap body, and the lock mechanism is disposed at a position further separated radially than the position of the upper limit stop member.
