Abstract
The present invention relates generally to a fastener retaining system (FRS) and kit for securing a fastener (such as a screw) to a driver (such as a screwdriver) to facilitate one-handed use of the driver in both fastening and un-fastening operations.
Claims17
A system for retaining a fastener against a driver bit, the system comprising:
- a resiliently flexible sleeve having an inner surface, a longitudinal axis and at least one driver shaft engaging surface for frictional engagement against a driver shaft having at least one driver shaft surface, the sleeve including at least three of an odd number of evenly-sized generally arcuate leaflets, the generally arcuate leaflets each having a generally arcuate outer edge extending inwardly from the inner surface of the resiliently flexible sleeve for engagement over and around the head of a fastener wherein the inwardly projecting generally arcuate leaflets are sized to promote centering a fastener within the system.
A system as in claim l, wherein the generally arcuate outer edges of adjacent leaflets abut adjacent generally arcuate outer edges of an adjacent leaflet thereby defining an abutment region and wherein the abutment region extends greater than 50% of the distance between the sleeve and a central axis of the sleeve.
A system for retaining a fastener against a driver bit, the system comprising:
- a resiliently flexible sleeve for frictional engagement against a driver shaft, the sleeve having an inner surface, a longitudinal axis and a triangular cross section having three inwardly convex shaft engaging surfaces, the sleeve further including three evenly-sized generally arcuate leaflets each having a generally arcuate outer edge extending inwardly from the inner surface of the resiliently flexible sleeve for engagement over and around the head of a fastener and wherein each leaflet has a horizontal length from the inner surface of the sleeve to the longitudinal axis of the sleeve that is less than the vertical displacement of each leaflet from the first end of the sleeve.
A system for retaining a fastener against a driver bit, the system comprising:
- a resiliently flexible sleeve portion with an outer surface and a driver shaft engaging inner surface for frictional engagement with an outer surface of a driver shaft, said sleeve portion having an upper driver shaft opening;
- and
- a resiliently flexible fastener engagement sleeve lower section formed integrally with said resiliently flexible sleeve portion, said sleeve lower section having a sleeve lower section outer surface forming a continuation of said sleeve portion outer surface having a sleeve lower section inner surface forming a continuation of said sleeve portion inner surface, said sleeve lower section having a lower edge defining a fastener opening for receiving a head portion of a fastener through said fastener opening and said sleeve lower section having at least three evenly-sized generally arcuate leaflets comprising an odd number of said generally arcuate leaflets connected to said sleeve lower section inner surface adjacent to said fastener opening, each of said generally arcuate leaflets projecting radially inwardly from said sleeve lower section inner surface toward a central axis of said sleeve lower section and having a generally arcuate outer edge extending inwardly from the lower section inner surface of the sleeve defining fastener centering means for engagement over and around the head portion for centering the head portion within said sleeve lower section and relative to said inner driver shaft engaging surface.
