1. A shock absorber for supporting a protective faceguard relative to a head-engaging member, the shock absorber comprising:
a support structure adapted for attachment to one of the head-engaging member and the faceguard; a guide rod supported by said support structure in a fixed position relative to said support structure, said guide rod having first and second end portions, a length, and a longitudinal axis; a sliding member guided by said guide rod for rectilinear movement in a direction parallel to said longitudinal axis of said guide rod, said sliding member being adapted for attachment to another one of the head engaging member and the faceguard; and a resilient member acting on said sliding member to bias said sliding member toward said first end portion of said guide rod, wherein said resilient member can absorb at least a portion of the impact energy of an object impacting the faceguard when the impact causes said sliding member to move toward said second end portion of said guide rod, wherein said sliding member has an opening therethrough and said guide rod extends through said opening, and wherein said support structure supports said guide rod at said first end portion of said guide rod and at said second end portion of said guide rod. |
