Abstract

A front cabinet panel piece, a back panel cabinet piece, a first side cabinet panel piece, and second side cabinet panel piece, each having a plurality of pre-formed openings, are arranged relative to one another to form an amusement game cabinet. The plurality of pre-formed openings are used to accept a corresponding plurality of knock-down hardware pieces each including a fastener locking component and a fastener. The fastener locking components are held within respective first ones of the pre-formed openings and the fastener is inserted into second ones of the pre-formed openings that are aligned with the first ones of the plurality of pre-formed openings. Each fastener is mated to its corresponding fastener locking component to complete assembly of the amusement game cabinet. The assembled amusement game cabinet is used to support a playfield and the playfield, in turn, is used to provide additional structural support to the amusement game cabinet.

Claims (27)

1. An electromagnet assembly for use in connection with an amusement game having a playfield and an object which moves across a first surface of the playfield, comprising:

a magnet core constructed from a ferromagnetic material;

a protector element constructed from a non-ferromagnetic material attached to a first end of the magnet core, the protector element encircling the magnet core and arranged relative to the magnet core such that a first planar surface of the protector element which is to be exposed on the first surface of the playfield is flush to a planar surface of the magnet core which is also to be exposed on the first surface of the playfield; and

a magnet connector assembly disposable around the magnet core for activating the magnet core under control of a processing device of the amusement game;

wherein the protector element is sized to define an area on the first surface of the playfield that is larger than an area on the first surface of the playfield in which the object may oscillate when the magnet core is activated for the purpose of capturing the object upon the first surface of the playfield.

2. The electromagnet assembly as recited in claim 1 , wherein the protector element is constructed from stainless steel.

3. The electromagnet assembly as recited in claim 1 , further comprising a magnet mounting plate for carrying each of the magnet core and the magnet connector assembly and for attaching the magnet core and the magnet connector assembly to a second surface of the playfield opposite to the first surface of the playfield.

4. The electromagnet assembly as recited in claim 3 , wherein the magnet mounting plate has an opening in which is positioned the magnet core.

5. The electromagnet assembly as recited in claim 4 , wherein the magnet mounting plate has a first surface upon which the magnet connector assembly is disposed.

6. The electromagnet assembly as recited in claim 5 , further comprising a locking element attachable to a second end of the magnet core adjacent to a second surface of the magnet mounting plate for securing the magnet connector assembly between the first surface of the magnet mounting plate and a second surface of the protector element and wherein the second surface of the protector element is opposite to the first surface of the protector element and the second surface of the magnet mounting plate is opposite to the first surface of the magnet mounting plate.

7. The electromagnet assembly as recited in claim 6 , further comprising at least a pair of mounting blocks attachable to the first surface of the magnet mounting plate, the mounting blocks each accepting at least one fastener for allowing the magnet mounting plate to be attached and adjustably positioned relative to the second surface of the playfield.

8. An amusement game, comprising:

a game cabinet;

a playfield mounted within the game cabinet;

a processing device;

an object which moves across a first surface of the playfield; and

an electromagnet assembly coupled to the processing device and associated with the playfield, the electromagnet assembly comprising:

a magnet core constructed from a ferromagnetic material;

a protector element constructed from a non-ferromagnetic material attached to a first end of the magnet core, the protector element encircling the magnet core and arranged relative to the magnet core such that a first planar surface of the protector element which is exposed on the first surface of the playfield is flush to a planar surface of the magnet core which is also exposed on the first surface of the playfield; and

a magnet connector assembly disposed around the magnet core for activating the magnet core under control of the processing device of the amusement game;

wherein the protector element is sized to define an area on the first surface of the playfield that is larger than an area on the first surface of the playfield in which the object may oscillate when the magnet core is activated for the purpose of capturing the object upon the first surface of the playfield.

9. The amusement game as recited in claim 8 , wherein the protector element is constructed from stainless steel.

10. The amusement game as recited in claim 8 , wherein the electromagnet assembly further comprises a magnet mounting plate for carrying each of the magnet core and the magnet connector assembly and for attaching the magnet core and the magnet connector assembly to a second surface of the playfield opposite to the first surface of the playfield.

11. The amusement game as recited in claim 10 , wherein the magnet mounting plate has an opening in which is positioned the magnet core.

12. The amusement game as recited in claim 11 , wherein the magnet mounting plate has a first surface upon which the magnet mounting assembly is disposed.

13. The amusement game as recited in claim 12 , wherein the electromagnet assembly further comprises a locking element attachable to a second end of the magnet core adjacent to a second surface of the magnet mounting plate for securing the magnet connector assembly between the first surface of the magnet mounting plate and a second surface of the protector element and wherein the second surface of the protector element is opposite to the first surface of the protector element and the second surface of the magnet mounting plate is opposite to the first surface of the magnet mounting plate.

14. The amusement game as recited in claim 13 , wherein the electromagnet assembly further comprises at least a pair of mounting blocks attachable to the first surface of the magnet mounting plate, the mounting blocks each accepting at least one fastener for allowing the magnet mounting plate to be attached and adjustably positioned relative to the second surface of the playfield.
