Abstract
A riot faceshield assembly is provided which can be utilized with a wide range of protective helmet designs and sizes, which provides a positive sealing relationship between the faceshield and the front brim of the helmet, which may be pivoted into and conveniently locked in the protective position, and which includes a positive stop member to prevent the faceshield from pivoting downwardly into contact with a wearer's neck or chest when impacted. The faceshield assembly includes a three point or triangular retention system which assures integrity of the unit in the event of either upwardly or downwardly directed impacts.
Claims8
A riot faceshield assembly adapted for use with a variety of protective helmets of varying sizes, comprising:
- a transparent protective faceshield member for protecting the face of a user;
- first and second bracket members, each of said bracket members including intermediate faceshield member fastening means for pivotally securing said faceshield member for movement between a protective orientation and an upraised position, each of said bracket members further including front and rear helmet engaging arms for engaging the edge of said helmet at positions in front of and behind the position of said intermediate faceshield member fastening means to limit the upward movement of said faceshield assembly relative to said helmet;
- said intermediate faceshield member fastening means including at least two distinct pivot points to which said faceshield member may be pivotally secured, to permit said faceshield member to be adjusted in position relative to said front edge of said helmet to maintain said generally sealing relationship with helmets of different dimensions;
- strap means secured at one end adjacent one of said bracket members and at its other end adjacent the other of said bracket members and adapted to be positioned over the top of said helmet to provide an upward bias upon said bracket members to urge said engaging arms against said edge of said helmet;
- further wherein said bracket members are configured relative to said helmet to bring said faceshield member into a generally sealing relationship with the front edge of said helmet when said faceshield member is pivoted into its protective orientation;
- and
- means for preventing said faceshield member from pivoting beyond said protective orientation, wherein said preventing means includes a solid pin member secured within each of said bracket members and positioned to rest in groove means in said faceshield member when said faceshield member is pivoted into said protective orientation, said pin members being movable to different positions relative to said bracket members to correspond to movement of said faceshield member between said at least two distinct pivot points.
