Abstract: A driver tool for small nails and brads having a tubular body within which a plunger is reciprocal. The upper end of the plunger and the body are connected by an elastomeric member so that a manual force may be applied to draw the plunger upward. Upon release, the plunger descends to impact the nail or brad within the lower end of the tubular body. The lower driver head end of the plunger is magnetized.

Abstract: A lockable quick release assembly for securing removable parts such as a wheel to the fork of a bicycle frame with the assembly including a specialized handle which not only rotates a cam shaped member within the interior of the assembly but has a key means which allows locking of the assembly to the frame to prevent theft of the wheel. The assembly also has means to secure the handle to the assembly so it will not fall off during normal use of the bicycle, but can be removed if desired.

Abstract: A pitching and batting conditioning device which is characterized in a first preferred embodiment by single and multiple drum conditioning devices having a drum spool for receiving a weight line attached to a weight and one or more drums of the same or different diameters for receiving a conditioning line or lines attached to a baseball bat or ball. Conditioning of the arm or arms and upper body is achieved by grasping the bat or ball and swinging the bat or simulating throwing the ball against the resistance of the weight. In another embodiment a multiple spring conditioning device also includes a conditioning line attached to a bat or ball and an adjustable feature for engaging springs of varying tension for application to the conditioning line. In a third embodiment a torsion spring is mounted in a housing with an adjustable torsional feature and includes a drum, upon which is wound a conditioning line attached to a bat or ball.
