Abstract: This disclosure relates to a golf club holder configured to support a golf club with an offset head in a grip-up, head-down orientation. More specifically, the disclosed golf club holder includes a body having a shaft-engaging portion, a head-engaging portion, and a middle portion between the shaft-engaging portion and head-engaging portion. A ground-engaging base extends from the head-engaging portion, supporting the body in a substantially vertical orientation. The shaft-engaging portion removably secures the shaft of a golf club. The middle portion includes an opening providing clearance for a bent club shaft or hosel. The head-engaging portion removably secures the angled offset head of the golf club. Pushing the club downwards presses the club head against a lower stop, forcing the ground-engaging base into the ground. Pulling the club upwards presses the club head against an upper stop, lifting the ground-engaging based from the ground.

Abstract: A push and release operator control for selectively opening or closing the discharge blocking flap of a lawnmower. The first portion of travel of the actuator raises the discharge blocking flap toward its balance point. As the blocking flap reaches the balance point the actuator is released which allows the blocking flaps momentum to carry it through the balance point where gravity takes over to finish the travel. The actuator is reset by the blocking flaps motion after passing the balance point. Once the actuator is reset by the blocking flaps travel the same push and release of the actuator will return the blocking flap to it original starting position.

Abstract: A force indicating device for monitoring acceleration forces developed during the motion an object. The device, when attached to a swinging or rotated sports implement, can be used to improve the speed and consistency with which the implement is swung.
