Abstract
Abstract The invention relates to a play feature for a pinball game able to assume a plurality of scoring positions. Various embodiments are disclosed, including two-position targets and four-position targets. The devices are actuated by a solenoid which cooperates with a cam to provide linear or rotary output to change the target position. The solenoids are actuated by a switch associated with the targets. The positions of the targets are sensed to provide different scoring values for each of the different positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
In a flipper-type pinball game machine of the type having an inclined playfield which supports a rolling ball and one or more play features, the improved play feature comprising: (1) a ball target means; (2) a positioning means for movably positioning said ball target means comprising a solenoid having a plunger-shaft arranged perpendicular to and extensible above the playfield to carry said ball target means, a camming pin carried by said plunger-shaft, and a cam means having a cam track into which said camming pin extends to control movement of said plunger shaft; (3) a sensing means for sensing the position of said camming pin and plunger shaft for registering a score based on the position; and (4) an activating means for activating said positioning means.
Claim 2
Dependent Claim
126 words
In a flipper-type pinball game machine of the type having an inclined playfield which supports a rolling ball and one or more play features, the improved play feature comprising: (1) a ball target means; (2) a positioning means for movably positioning said ball target means comprising a solenoid having a plunger-shaft arranged perpendicular to and extensible above the playfield to carry said ball target means, a camming pin carried by said plunger-shaft, and a cam means having a cam track into which said camming pin extends to control movement of said plunger shaft; (3) a sensing means for sensing the position of said camming pin and plunger shaft for registering a score based on the position; and (4) an activating means for activating said positioning means.
Claim 3
Dependent Claim
39 words
The play feature of claim 1, wherein said cam track has a substantially triangular path for locking said camming pin in a first and second position, said path gradually becoming shallower as it is traversed by said camming pin.
Claim 4
Dependent Claim
13 words
The play feature of claim 1 wherein said sensing means comprises a microswitch.
Claim 5
Dependent Claim
21 words
The play feature of claim 1, wherein said activating means comprises a switch means operatively connected to said ball target means.
Claim 6
Dependent Claim
106 words
A playfield feature for a pinball game having an inclined playfield which supports a rolling ball for movement thereon comprising: a. a ball target; b. A solenoid having a shaft on which said ball target is disposed, whereby actuation of said solenoid moves said shaft and target from a first position to a second position; c. a camming pin carried by said shaft; and d. camming means traversed by said pin for holding said pin upon movement of the shaft from said first position to said second position and for releasing said pin upon a second actuation of said solenoid, and means for activating said solenoid.
Claim 7
Dependent Claim
106 words
A playfield feature for a pinball game having an inclined playfield which supports a rolling ball for movement thereon comprising: a. a ball target; b. A solenoid having a shaft on which said ball target is disposed, whereby actuation of said solenoid moves said shaft and target from a first position to a second position; c. a camming pin carried by said shaft; and d. camming means traversed by said pin for holding said pin upon movement of the shaft from said first position to said second position and for releasing said pin upon a second actuation of said solenoid, and means for activating said solenoid.
Claim 8
Dependent Claim
26 words
The playfield feature of claim 5 further including means for returning said shaft and target to said first position upon said second actuation of said solenoid.
Claim 9
Dependent Claim
19 words
The playfield feature of claim 6 wherein said returning means is a concentrically mounted spring disposed on said shaft.
Claim 10
Dependent Claim
30 words
The playfield feature of claim 5 wherein said camming means includes a cam track with a triangular path, a portion of said path configured to releasably secure said camming pin.
