Abstract

This multifunction device was designed to retain a panhead screw to a steel bar (pressure bar) while allowing access to the head for driving the screw. It prevents the driving tool from losing contact with the screw head (sliding off) and damaging the circuit board below. It provides a handle to the bar, to which it is fastened, so as to allow the user to lift the bar from within a deep crevice of the system in which this device is used. This handle automatically maintains proper orientation for use, regardless of the position of the bar. Furthermore, a molded feature on the retainer provides a method to hold the bar in a vertical position so as to allow user access to the circuit board to which the bar fastens. Molded features of this retainer engage the end of the bar and snap into features at the top of the bar. This device is an elegant, simple, low cost, efficient solution to a complicated problem. Figure 1, illustrates the retainer installed onto the steel bar with the retained screw, and the attached handle. Also visible is the tip of the screw driver, as it is held in contact with head of the screw. 1

Multifunction Screw Retainer

This multifunction device was designed to retain a panhead screw to a steel bar (pressure bar) while allowing access to the head for driving the screw. It prevents the driving tool from losing contact with the screw head (sliding off) and damaging the circuit board below. It provides a handle to the bar, to which it is fastened, so as to allow the user to lift the bar from within a deep crevice of the system in which this device is used. This handle automatically maintains proper orientation for use, regardless of the position of the bar. Furthermore, a molded feature on the retainer provides a method to hold the bar in a vertical position so as to allow user access to the circuit board to which the bar fastens. Molded features of this retainer engage the end of the bar and snap into features at the top of the bar.

This device is an elegant, simple, low cost, efficient solution to a complicated problem.

Figure 1, illustrates the retainer installed onto the steel bar with the retained screw, and the attached handle. Also visible is the tip of the screw driver, as it is held in contact with head of the screw.

Figure 2, highlights the retainer's attachment features as they engage the steel bar at its top and end. The head of the screw is confined to a elongated spherical area under the top of the retainer and the handle snaps onto the end of the retainer.
