摘要

1375650 Golf ball ejector McCULLOCH CORP 27 Sept 1972 [5 Oct 1971 8 Sept 1972] 44668/72 Heading A6D A golf ball ejector apparatus 1 which may be sunk in a putting green comprises a ball receiving cup 6, a diaphragm 10 operable to impact a golf ball 73 out of the cup, energising means operable to effect ball impacting movement of the diaphragm and control means 37 operable to actuate the energising means in response to flexing of the diaphragm 10. In the embodiment shown the diaphragm 10 has a bellows formation and is supported on a cup 13 having an extension 78 carrying a coil 12 which extends into a recess 17 in a magnet assembly 14. The cup 13 is mounted with slight resilience so that a ball contacting the diaphragm 10 will slightly depress the cup 13 and the coil 12 in the recess 17 thereby producing a signal in the coil which is transmitted to. the control circuit panel 37. The signal is used to operate the energising device consisting of a battery pack 29 which sends current back to the coil 12 thereby causing an upward impact movement of the cup 13 which is transmitted through the diaphragm 10 to the ball 73 to eject it in a random manner from the cup 6. The device is constructed so as to be sealed from environmental conditions. A second embodiment with slight variations is described.
