Abstract
Abstract The present invention provides a ball and net game device having several levels of net board whose mesh is just large enough to let a ball pass through, a projector free to change its projection angle to project said ball on an uppermost net board and a detector microswitch to detect said ball dropping in a specified mesh, said detector in electric connection to operate a prize ball discharger and a slide-film projector.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
In a ball and net game device, a plurality of net boards respectively situated at given levels one above the other and including at least one uppermost net board and at least one net board situated beneath and being parallel to said uppermost net board, said net boards each having meshes of a predetermined cross-sectional area, a ball to be projected onto said uppermost net board to fall through a mesh of the latter and then through a mesh of the next lower net board, said ball having a diameter which renders each mesh of each net board just large enough to permit the ball to fall through any mesh of the net boards, each net board carrying at the region of at least one mesh thereof a microswitch situated in the path of movement of the ball when the latter falls through said one mesh of each net board so that the microswitch will then be actuated by the ball, and means responding to actuation of a microswitch for providing a predetermined response to the falling of the ball through that one mesh of a given net board where the microswitch is located.
Claim 2
Dependent Claim
194 words
In a ball and net game device, a plurality of net boards respectively situated at given levels one above the other and including at least one uppermost net board and at least one net board situated beneath and being parallel to said uppermost net board, said net boards each having meshes of a predetermined cross-sectional area, a ball to be projected onto said uppermost net board to fall through a mesh of the latter and then through a mesh of the next lower net board, said ball having a diameter which renders each mesh of each net board just large enough to permit the ball to fall through any mesh of the net boards, each net board carrying at the region of at least one mesh thereof a microswitch situated in the path of movement of the ball when the latter falls through said one mesh of each net board so that the microswitch will then be actuated by the ball, and means responding to actuation of a microswitch for providing a predetermined response to the falling of the ball through that one mesh of a given net board where the microswitch is located.
Claim 3
Dependent Claim
61 words
The combination of claim 1 and wherein a screen is situated at the region of said uppermost net board in a position to be viewed by a player of the game, and a projector for projecting slides onto the screen to be viewed by the player, said projector forming the means which responds to actuation of a microswitch by said ball.
Claim 4
Dependent Claim
95 words
The combination of claim 1 and wherein a projector is situated at an edge region of said uppermost net board for projecting said ball onto said uppermost net board, guide means coacting with said projector for guiding balls thereto, a reservoir of prize balls, and conveyer means cooperating with said reservoir for conveying prize balls from the latter to said guide means to be delivered to said projector, said conveyer means forming said means which responds to actuation of a microswitch by falling of a ball through said one mesh of a given net board.
Claim 5
Dependent Claim
70 words
The combination of claim 3 and wherein a screen is situated at the region of said uppermost net board in a position to be viewed by a player, and a slide projector for projecting slides onto said screen, said slide projector forming also part of means which responds to actuation of a microswitch by said ball for changing the slides to change a scene which is projected onto said screen.
Claim 6
Dependent Claim
66 words
The combination of claim 1 and wherein a series of net boards are respectively situated at predetermined elevations one above the other terminating at the uppermost level in said uppermost net board, said uppermost net board carrying a plurality of said microswitches at a plurality of predetermined meshes thereof while each of the successive lower net boards carries only one microswitch at a given mesh thereof.
Claim 7
Dependent Claim
51 words
The combination of claim 1 and wherein at least at said uppermost net board there is a U-shaped ball-receiving element aliGned with said one mesh where said microswitch is located for receiving a ball which approaches said one mesh and aiding in the guiding of said ball through said one mesh.
Claim 8
Dependent Claim
39 words
The combination of claim 1 and wherein a ball-projector means capable of being swivelled by the operator for aiming a ball is situated at the region of an edge of said uppermost net board for projecting said ball therealong.
