Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A single lever joy-stick apparatus comprising a housing, first and second slotted motion transmitting members pivotally mounted in said housing such that their respective pivot axes perpendicularly intersect, a joy-stick having a spherical ball having a smooth, uninterrupted convex outer surface attached to its shaft, portions of said shaft of said joy-sTick engaging said motion transmitting members at bearing surfaces defined by said slots, each of said motion transmitting members having oppositely disposed substantially concave bearing surfaces intermediate their respective ends, mating with the convex outer surface of said spherical ball for supporting said ball in its operational position, the center of said spherical ball corresponds to the point at which the respective pivot axes of said first and second motion transmitting members intersect.
Claim 2
Dependent Claim
124 words
A single lever joy-stick apparatus comprising a housing, first and second slotted motion transmitting members pivotally mounted in said housing such that their respective pivot axes perpendicularly intersect, a joy-stick having a spherical ball having a smooth, uninterrupted convex outer surface attached to its shaft, portions of said shaft of said joy-sTick engaging said motion transmitting members at bearing surfaces defined by said slots, each of said motion transmitting members having oppositely disposed substantially concave bearing surfaces intermediate their respective ends, mating with the convex outer surface of said spherical ball for supporting said ball in its operational position, the center of said spherical ball corresponds to the point at which the respective pivot axes of said first and second motion transmitting members intersect.
Claim 3
Dependent Claim
32 words
A single lever joy-stick apparatus according to claim 1 wherein each of said motion transmitting members are provided with at least one output extension for driving the cores of a push-pull cable.
Claim 4
Dependent Claim
31 words
A single lever joy-stick apparatus according to claim 2 wherein said core is disposed for axial movement within a conduit, said conduit being rockably attached to said housing by holding means.
Claim 5
Dependent Claim
29 words
A single lever joy-stick apparatus according to claim 3 wherein there are two push-pull cables the core of each respectively attached to the first and second motion transmitting members.
Claim 6
Dependent Claim
37 words
A single lever joy-stick apparatus according to claim 4 wherein said conduit has a grooved end fitting attached thereto and said holding means further includes a substantially U shaped member engaging said end fitting at said groove.
Claim 7
Dependent Claim
60 words
A single lever joy-stick apparatus according to claim 1 wherein said ball is attached to said shaft at a distance from its end, the upper portion of said shaft engaging said first motion transmitting member and said lower portion of said shaft engaging said second motion transmitting member at each of their respective bearing surfaces as defined by said slots.
Claim 8
Dependent Claim
60 words
A single lever joy-stick apparatus according to claim 2 wherein said output extensions include a bar fixedly attached at one of its ends to each of said motion transmitting members and said bars being provided with an aperture at the opposite ends thereof, said cores being provided with attaching means for attaching said cores to said bars at said apertures.
Claim 9
Dependent Claim
44 words
A single lever joy-stick apparatus according to claim 7 wherein said attaching means includes a yoke fixedly attached to end of said core, said yoke having aligned apertures therein, holding pin means disposed at said apertures and engaging said bars at said bar apertures.
Claim 10
Dependent Claim
34 words
A single lever joy-stick apparatus according to claim 1 wherein first and second slotted motion transmitting members are pivotally mounted in bearings in said housing and said joy-stick is further provided with a knob.
