Abstract
The invention relates to an adjustable helmet having a front shell and a back shell that are movably secured to one another and that comprise engaging members that may be held together by a locking mechanism comprising a cam that pivots about an axis extending in a direction that is substantially parallel to a side portion of the helmet. The locking mechanism of the present invention has the advantage of exerting a compressive force on a substantial portion of the engaging members thereby providing a more solid engagement. The locking mechanism also has the advantage of being easily replaceable by a conventional mounting screw assembly. The helmet of the present invention is particularly well suited for use in hockey or other like sports.
Claims11
An adjustable helmet comprising a front shell and a back shell moveable relative to one another, each of said front and back shells comprising a plurality of engaging members to allow said front shell to be secured to said back shell in a selected position, said helmet further comprising a locking mechanism having a cam being pivotable about a pivot axis to acquire either one of a locking position and an adjustment position, in said locking position, said cam exerting a force on said engaging members of either one of said front and back shells so that they interact with corresponding engaging members of the other one of said front and back shells to secure said front and back shells in a selected position, and in said adjustment position, said cam being pivoted about said axis so as to allow said front shell to move relative to said back shell, said pivot axis extending in a direction that is generally transverse relative to said engaging members, said axis being defined by the projecting arms of a clevis member, said arms extending through longitudinal slots located on either one of said front and back shells, said cam being pivotally connected to said arms.
