Helmet visor support apparatus

Helmet visor support apparatus, comprising:

• a visor support arm having an attachment end and a visor-holding end, pivotally attached at the attachment end to the helmet at a pivot point, for moving the visor between a raised and a lowered position;
• a positioning means rotatably attached to the helmet at the pivot point, said positioning means having at least two bores extending thereinto corresponding to the raised and lowered positions;
• a locking pin for retractably engaging either one of the bores in said poisitioning means, said locking pin comprising a head at one end thereof which has a diameter sized to engage the bores, and a stem which has a diameter smaller than that of said head;
• a hollow, generally cylindrical encasement fixed to said visor support arm and sized to closely encase said locking pin therwithin, whereby said locking pin is operatively connected to lock said visor support arm in position when said locking pin is engaged in one of the bores;
• a spring coiled around said stem and having a diameter less than or equal to the diameter of said head;
• an inner rim fixed to one end of said cylindrical encasement to urge said spring against said head of said locking pin, said inner rim being sized to provide a circular hole through which said stem slidably fits;
• a handle attached to said locking pin for retracting said locking pin from the one of the bores, thereby allowing said visor support arm to pivot;
• a narrow tab extending from said handle and oriented to slidably fit through a slot in said visor support arm, for preventing rotation of said locking pin;
• and
• a curved spring washer rotatably fixed to the helmet at the pivot point for providing sufficient friction for controllably moving the visor between the raised and lowered positions.

Helmet visor support apparatus, comprising:

• a visor support arm having an attachment end and a visor-holding end, pivotally attached at the attachment end to a helmet at a pivot point, for moving the visor between a raised and a lowered position;
• a positioning means attached to the helmet at the pivot point, said positioning means having at least two bores corresponding to the raised and lowered visor positions;
• a locking pin for retractably engaging either one of the bores in said positioning means, and operatively connected to lock said visor support arm in position when so engaged, said locking pin comprising a head at one end thereof which has a diameter sized to engage the bores, and a stem which has a diameter smaller than that of said head;
• a hollow, generally cylindrical encasement fixed to said visor support arm and sized to closely encase said locking pin therewithin, whereby said locking pin is operatively connected to lock said visor support arm in position when said locking pin is engaged in one of the bores;
• a biasing means operatively connected to said visor support arm to normally bias the locking pin in engagement with one of the bores, said biasing means comprising a spring coiled around said stem of said locking pin and having a diameter less than or equal to the diameter of said head, and an inner rim fixed to one end of said cylindrical encasement to urge said spring against said head of said locking pin;
• and
• a manually activatable retracting means attached to said locking pin and operatively connected to release said biasing means and retract said locking pin from the one of the bores upon being manually activated thereby allowing said visor support arm to pivot, said retracting means being mounted on said visor support arm between the two ends thereof and positioned to be activated by manual movement away from the attachment end of said visor support arm and towards the visor-holding end thereof.
