Anti-rotation target assembly for an amusement game device
A target assembly for an amusement device includes a switch stack comprising a target leaf spring, a contact leaf spring, and a spacer electrically isolating the target leaf spring from the contact leaf spring. An anti-rotation shell is mounted to the switch stack and at least partially surrounds one end of the target leaf spring and the contact leaf spring. The anti-rotation shell is sized and configured to substantially prevent relative movement between the target leaf spring and the contact leaf spring. In some examples, a switch mount bracket includes slot to receive side walls of the anti-rotation shell.
1. A target assembly for an amusement device comprising:
a switch stack comprising a target leaf spring, a contact leaf spring, and a spacer electrically isolating the target leaf spring from the contact leaf spring; and
an anti-rotation shell mounted to the switch stack and at least partially surrounding one end of the target leaf spring and the contact leaf spring, the anti-rotation shell sized and configured to substantially prevent relative movement between the target leaf spring and the contact leaf spring.
2. The target assembly as defined in claim 1 , further comprising a fastener mounting the anti-rotation shell to the switch stack and extending through apertures defined in the target leaf spring, the contact leaf spring, the spacer, and the anti-rotation shell.
3. The target assembly as defined in claim 2 , further comprising a switch mount bracket coupled to the switch stack and the anti-rotation shell for mounting the target assembly to the amusement device.
4. The target assembly as defined in claim 3 , wherein the anti-rotation shell comprises a back wall, a first side wall extending generally perpendicular from a first edge of the back wall, and a second side wall extending generally perpendicular from a second edge of the back wall.
5. The target assembly as defined in claim 4 , wherein the anti-rotation shell comprises an electrically non-conductive material.
6. The target assembly as defined in claim 4 , wherein the switch mount bracket comprises a first slot to receive the first side wall of the anti-rotation shell and a second slot to receive the second side wall of the anti-rotation shell.
7. The target assembly as defined in claim 6 , wherein the first side wall comprises a notch to size the first side wall to fit into the first slot.
8. The target assembly as defined in claim 7 , wherein the second side wall comprises a notch to size the second side wall to fit into the second slot.
9. The target assembly as defined in claim 3 , further comprising a deflection stop coupled to the anti-rotation shell and extending parallel to the target leaf spring and the contact leaf spring.
10. The target assembly as defined in claim 9 , wherein the anti-rotation shell is disposed between the deflection stop and the contact leaf spring.
11. An anti-rotation shell for housing a switch stack of a leaf spring target assembly, the anti-rotation shell comprising:
a back wall;
a deflection stop coupled to the back wall;
a first side wall extending generally perpendicular from a first edge of the back wall;
a second side wall extending generally perpendicular from a second edge of the back wall; and
a switch mount bracket located opposite the back wall, wherein the switch stack is to be located between the switch mount bracket and the back wall, the switch mount bracket comprising a first slot to receive the first side wall of the anti-rotation shell and a second slot to receive the second side wall of the anti-rotation shell,
wherein together, the back wall, the first side wall, and the second side wall define a space for receiving the switch stack at least partially therein.
12. The anti-rotation shell as defined in claim 11 , wherein the first side wall comprises a notch to size the first side wall to fit into the first slot.
13. The anti-rotation shell as defined in claim 11 , wherein the second side wall comprises a notch to size the second side wall to fit into the second slot.
14. The anti-rotation shell as defined in claim 11 , wherein the first side wall and the second side wall comprise an electrically non-conductive material.
