Abstract
A helmet is provided which is to be worn on the head of a helmet wearer and can be removed from the head with a comparatively small force. Operation for removing the helmet, including preliminary operation for it, can be performed easily and quickly. A recess-projection engaging mechanism to attach a blockish inside pad to a head protecting cap portion side includes an engaging pin on the inside pad side or head protecting cap portion side, and a notched engaging hole on the head protecting cap portion side or inside pad side. When pulling the inside pad outward from inside the head protecting cap portion at least partly, the engaging pin moves relative to outside the engaging hole through a notch of the engaging hole.
Claims36
A helmet comprising:
- (a) a head protecting cap portion comprising an inner surface;
- (b) at least one blockish inside pad, wherein said at least one blockish inside pad is configured to be disposed within said head protecting cap portion;
- and
- (c) at least one connecting mechanism comprising:
- (i) a recess-projection engaging mechanism comprising;
- (A) an engaging pin non-slidably and mechanically coupled to either said at least one blockish inside pad or said inner surface;
- and
- (B) a channel disposed on the other of said at least one blockish inside pad or said inner surface, the channel comprising;
- (I) a notched engaging hole;
- (II) a mouth;
- and
- (III) a narrow portion, wherein said narrow portion connects said mouth to said notched engaging hole to form said channel, wherein said channel is substantially parallel to said inner surface of said head protecting cap portion when said at least one blockish inside pad is retained within said head protecting cap portion;
- wherein said at least one connecting mechanism is configured to removably attach said at least one blockish inside pad to said inner surface of said head protecting cap portion by retaining said engaging pin within said notched engaging hole by moving said engaging pin into said channel at said mouth through said narrow portion to said notched engaging hole, and by directly pulling said at least one blockish inside pad to substantially below the helmet from inside said head protecting cap portion at least partly, said engaging pin exits said channel from said notched engaging hole through said narrow portion and out said mouth simultaneously as the at least one blockish inside pad is directly pulled, thus disengaging said engaging pin from said notched engaging hole, and pulling said at least one blockish inside pad outward from inside said head protecting cap portion at least partly.
A method of removing, from a head of a helmet wearer, a helmet comprising a head protecting cap portion with one or a plurality of blockish inside pads disposed therein, at least one of the blockish inside pads being attached to the head protecting cap portion in advance by one or a plurality of connecting mechanisms, wherein the method comprises, when attaching the at least one blockish inside pad, using, as at least one of the connecting mechanisms, a recess-projection engaging mechanism including one of an engaging pin and a notched engaging hole disposed on the at least one blockish inside pad side, and a corresponding one of a notched engaging hole and an engaging pin disposed on the head protecting cap portion side to be able to engage with one of the engaging pin and the engaging hole, when removing the helmet worn on the head of the helmet wearer, first, pulling the at least one blockish inside pad outward from inside the head protecting cap portion to cause the engaging pin to relatively come out from the engaging hole through a notch of the engaging hole, thus disengaging the engaging pin from the engaging hole, and pulling the blockish inside pad outward from inside the head protecting cap portion at least partly, and removing the head protecting cap portion from the head of the helmet wearer.
A helmet comprising:
- (a) a head protecting cap portion comprising an inner surface;
- (b) at least one blockish inside pad, wherein said at least one blockish inside pad is configured to be disposed within said head protecting cap portion;
- and
- (c) a plurality of connecting mechanisms comprising:
- (i) a recess-projection engaging mechanism comprising;
- (A) an engaging pin non-slidably and mechanically coupled to either said at least one blockish inside pad or said inner surface, said engaging pin comprising a first male hook and a first female hook that form an engaging shaft portion;
- and
- (B) a channel disposed on the other of said at least one blockish inside pad or said inner surface, the channel comprising;
- (I) a notched engaging hole, wherein said engaging shaft portion engages said notched engaging hole;
- (II) a mouth;
- and
- (III) a narrow portion, wherein said narrow portion connects said mouth to said notched engaging hole to form said channel,
- wherein said channel is substantially parallel to said inner surface of said head protecting cap portion when said at least one blockish inside pad is retained within said head protecting cap portion;
- wherein at least one of said plurality of connecting mechanisms is configured to removably attach said at least one blockish inside pad to said inner surface of said head protecting cap portion by retaining said engaging pin within said notched engaging hole by moving said engaging pin into said channel at said mouth through said narrow portion to said notched engaging hole, and by directly pulling said at least one blockish inside pad from inside said head protecting cap portion to a position partly below the helmet so that said engaging pin exits said channel from said notched engaging hole through said narrow portion and out said mouth simultaneously as the at least one blockish inside pad is directly pulled, thus disengaging said engaging pin from said notched engaging hole.
A helmet comprising:
- (a) a head protecting cap portion comprising an inner surface;
- (b) at least one blockish inside pad, wherein said at least one blockish inside pad is configured to be disposed within said head protecting cap portion;
- and
- (c) a plurality of connecting mechanisms comprising:
- (i) a recess-projection engaging mechanism comprising;
- (A) an engaging pin non-slidably and mechanically coupled to either said at least one blockish inside pad or said inner surface;
- and
- (B) a channel disposed on the other of said at least one blockish inside pad or said inner surface, the channel comprising;
- (I) a notched engaging hole, wherein said engaging shaft portion engages said notched engaging hole;
- (II) a mouth;
- and
- (III) a narrow portion, wherein said narrow portion connects said mouth to said notched engaging hole to form said channel, wherein said channel is substantially parallel to said inner surface of said head protecting cap portion when said at least one blockish inside pad is retained within said head protecting cap portion;
- and
- (d) an inclined guide surface adjacent said notched engaging,
- wherein at least one of said plurality of connecting mechanisms is configured to removably attach said at least one blockish inside pad to said inner surface of said head protecting cap portion by retaining said engaging pin within said notched engaging hole by moving said engaging pin into said channel at said mouth through said narrow portion to said notched engaging hole, and by directly pulling said at least one blockish inside pad from inside said head protecting cap portion to a position partly below the helmet so that said engaging pin exits said channel from said notched engaging hole through said narrow portion and out said mouth simultaneously as the at least one blockish inside pad is directly pulled, wherein said inclined guide surface is configured to support said engaging pin after said engaging pin has exited said mouth of the channel thus disengaging said engaging pin from said notched engaging hole.
