Abstract: A reversible golf club holder for use with a display rack in which the holder is adapted to hold either a left handed or right handed golf club wood in an inverted position. The holder consists of a club interface attached to the top of a shaft support and a bracket. An inverted golf club head is supported by the club interface, and the shaft of the golf club is oriented in a preferred alignment by the shaft support. The shaft support comprises at least one lug that releasably attaches to a receptacle of the bracket. Separate lugs are used depending on if the club is right handed or left handed, which ensures that each type of club is in the preferred alignment. Multiple brackets can be attached to the same display rack allowing multiple golf clubs to be displayed on the same rack.

Abstract: A trigger assist system. The system utilizes a means to detect cycle progress of a pneumatic gun and communicates to a means to forcibly return the trigger to a released position. The trigger is forcibly released against the user's applied finger pressure allowing the gun to complete a cycle and come to position whereby the gun is ready to be fired, or cycled, again. The trigger assist system then relaxes the trigger allowing the user's applied pressure to again pull the trigger. In one embodiment, the means to detect cycle progress is a switchable pneumatic valve in communication with the bolt of the gun. In another embodiment, the means to detect cycle progress is an electronic circuit in communication with the trigger system. In one embodiment, the means to forcibly return the trigger to a released position is a pneumatic piston. In another embodiment, the means to forcibly return the trigger to a released position is an electronic solenoid.
