Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A control stick for a game comprising: a housing; support means within said housing having a frusto-conical surface with a flattened central area defining a rest area with at least four channels in said frusto-conical surface displaced from each other by 90° and inclined with respect to the horizontal when said housing is in a reference orientation and extending from common rest position at said rest area; detecting means mounted at a position of each said channel remote from said common rest position for each indicating displacement of said stick in one of four directions; a ball within said housing for rolling movement along any of said channels from said rest position in response to manual movement of said housing from said reference orientation and for causing a different control signal to be produced when said ball rolls into contact with each one of said detecting means.
Claim 2
Dependent Claim
147 words
A control stick for a game comprising: a housing; support means within said housing having a frusto-conical surface with a flattened central area defining a rest area with at least four channels in said frusto-conical surface displaced from each other by 90° and inclined with respect to the horizontal when said housing is in a reference orientation and extending from common rest position at said rest area; detecting means mounted at a position of each said channel remote from said common rest position for each indicating displacement of said stick in one of four directions; a ball within said housing for rolling movement along any of said channels from said rest position in response to manual movement of said housing from said reference orientation and for causing a different control signal to be produced when said ball rolls into contact with each one of said detecting means.
Claim 3
Dependent Claim
147 words
A stick as in claim 1 including second means disposed opposite said support means and having a frusto-conical surface with a flattened central area at a common rest position defining a rest area and at least four channels in said frusto-conical surface of said second means displaced from each other by 90° and inclined with respect to the horizontal when said housing is in said reference orientation and extending from said rest area of said second means, the inclination of said channels of said second means being opposite the inclination of said channels of said support means so that said ball rolls from the rest position of said second means along any of said channels of said second means in response to manual movement of said housing and a different control signal is produced when said ball rolls into contact with each one of said detecting means.
Claim 4
Dependent Claim
19 words
A stick according to claim 1, wherein at least one of the detecting means is a double-blade electric contact.
