Ski binding with screw retaining construction

Claim 1

A screw retainer for retaining a screw having an enlarged head with a predetermined diameter in a first member which is to be attached to a second member, such as a ski binding part and a base plate, by means of said screw retainer, said screw retainer comprising: an outer wall in the first member defining a longitudinal bore having an outer entrance and a head receiving portion with a diameter larger than the diameter of the head of the screw, at least one first elastic projection near said entrace extending from said outer wall into said bore in the projected area of the head of a screw in said head receiving portion for blocking the withdrawal of a screw whose head is in said head receiving portion, and at least one second elastic projection spaced longitudinally inwardly from said first projection by at least the length of the head of the screw and extending from said outer wall into said bore in the projected area of a screw head in said head receiving portion, said first and second projections being adapted to bend away from said entrance to permit entry of the screw head into said bore past said projections and to resist removal of the screw from said bore by engaging the top of the screw head, and said first and second projections being further adapted to retain a screw head between said first and second projections in the first member prior to attachment to the second member.
