Abstract

A joy stick assembly is characterized by a joy stick resiliently mounted in an aperture through a hand holdable housing and normally biased to a neutral position. The joy stick is manually pivotable at one of its ends in any one of a plurality of directions through a 360° arc, and has a conductive sphere at its opposite end. Four contacts are positioned at 90° increments around the sphere and out of contact therewith when the sphere is in its neutral position, and the joy stick is manipulatable to establish electrical connections between the sphere and individual ones or adjacent pairs of the contacts to provide a signal from the sphere to the contact or contacts. With separate electrical connections established between the sphere and the four contacts and a tv video game, the joy stick is manipulatable to apply nine discrete signals to the game, four upon electrical connections between the sphere and individual ones of the contacts, another four upon electrical connections between the sphere and adjacent pairs of contacts and a further one when the sphere is in its neutral position.

Claims

1. A joy stick assembly, comprising a housing having top, bottom and side walls and an opening through said top wall;

a joy stick extending through said opening, said joy stick having a resilient member around a medial portion thereof secured to said top wall in said opening and pivotally mounting said joy stick therein and on said housing in said opening for pivotal movement within said opening in any direction throughout a 360°

arc from an equilibrium position to an operative position and return and a member of electrically conductive material at a lowermost end thereof; and

a plurality of contact elements of electrically conductive material on said housing bottom wall in an array in surrounding relationship to said conductive member, said conductive member being out of engagement with said contacts when said joy stick is in said equilibrium position and each said contact being engageable by said conductive member upon movement of said conductive member through an arcuate path as a function of pivotal movement of said joy stick away from said equilibrium position in a predetermined direction to electrically connect said conductive member and said contacts.

2. A joy stick assembly as in claim 1, wherein said housing bottom wall has upwardly extending surface extensions for mounting said contacts above said bottom wall in said array around said conductive member.

3. A joy stick assembly as in claim 1, wherein said plurality of contacts comprises an array of four contacts positioned 90°

apart in surrounding relationship to said conductive member with the spacings between adjacent pairs of contacts being such that said joy stick is pivotable from said equilibrium position both to engage and electrically connect said conductive member with selected individual ones of said contacts and to simultaneously engage and electrically connect said conductive member with selected adjacent pairs of said contacts to electrically connect said selected adjacent pairs of contacts and said conductive member.

4. A joy stick assembly as in claim 1, wherein said joy stick comprises a tire valve stem having a resilient outer casing with an annular groove therein receiving said housing top wall around said opening to pivotally mount said joy stick on said housing, a manually manipulatable knob at an upper end of said tire valve stem for accommodating manual pivotal movement of said joy stick and a rod connected at its upper end to a lower end of said tire valve stem and mounting said conductive member at its lowermost end.

5. A joy stick assembly as in claim 1, wherein said conductive member comprises an electrically conductive sphere.

6. A joy stick assembly as in claim 1, including means for establishing separate electrical connections with each of said contacts and said conductive member.

7. A joy stick assembly as in claim 1, including switch means on said housing having a pair of switch contacts, said switch means being separate and distinct from said conductive member and said contact elements and being manually actuable to establish an electrical connection between said switch contacts.

8. A joy stick assembly as in claim 7, said housing top wall having a second opening therethrough and said switch means comprising a manually manipulatable actuator slidably received through said second opening, an electrically conductive surface on one end of said actuator, said pair of switch contacts being supported on said housing bottom wall in alignment with said conductive surface for contact therewith upon sliding movement of said actuator toward said switch contacts, and means for yieldably urging said actuator to an upper position to normally maintain a spacing between said switch contacts and said conductive surface, said actuator being manually movable downwardly against said urging means to bring said conductive surface into engagement with said switch contacts to establish said electrical connection therebetween.

9. A joy stick assembly as in claim 8, wherein said housing bottom wall has surface extensions for mounting said pair of switch contacts.

10. A joy stick assembly as in claim 1, wherein said housing comprises first and second housing portions connectable to define a chamber therebetween, said first housing portion having said top wall with said opening therein for pivotally mounting said joy stick with a lower end of said joy stick and said conductive member extending to the interior of said chamber, said second housing portion having said bottom wall and said contacts being mounted on said bottom wall in said array around said conductive member and to the interior of said chamber.

11. A joy stick assembly as in claim 1, including a plurality of electrical conductors, and means for connecting individual ones of said electrical conductors with respective ones of said contacts and with said conductive member, said housing having a second opening therethrough and said conductors extending through said second opening to the exterior of said housing.

12. A joy stick assembly, comprising a housing having an opening therethrough, a joy stick extending through said opening, said joy stick having a resilient member therearound pivotally mounting said joy stick on said housing in said opening for movement in any direction throughout a 360°

13. A joy stick assembly, comprising a housing having an opening therethrough;

a joy stick extending through said opening, said joy stick having a resilient member therearound pivotally mounting said joy stick on said housing in said opening for movement in any direction throughout an 360°
