Abstract
An erection system (22) which is responsive to the flow of air for erecting a gyroscope (1) is diclosed. The erection system includes a plurality of channels (26,28,30,32) having balls (42) disposed therein. The balls (42) are responsive to the gyroscope (1) being tilted from an erect attitude by a first relatively small predetermined angle (0.5.degree.) for rolling in the channels (20,28,30,32) to create an unbalanced flow of air through the erection system (22), which provides a force to erect the gyro (1), and are responsive to the gyroscope (1) being tilted by a second relatively large predetermined angle (10.degree.) for rolling in the channels (26,28,30,32) to negate the unbalanced air flow which disables the erection system (22).
Claims5
For a gyro of the type having a spinning rotor and means spinning therewith for providing a flow of air, and erection system characterized by:
- a plurality of channels, each of which extends in a different direction;
- means associated with the gyro and the erection system for directing the flow of air through the channels;
- air flow control means arranged with the channels and including
- a pair of balls disposed within each of the channels so as to roll therealong, each of the channels having a gate near an air inlet end and a gate near an air outlet end, the balls remaining stationary in the channels and away from the gates for permitting air to flow through the gates when the gyro is erect, whereby the flow of air through the erection system is balanced, one of the balls in a first of the channels rolling in said channel to the gate near the inlet end thereof and cooperating with said gate to prevent air from entering the channels and thereby blocking the flow of air through the first channel when the gyro is tilted from the erect by more than a first relatively small predetermined angle and less than a second relatively large predetermined angle, and one of the balls in a second of the channels rolling in said channel to the gate near the outlet end thereof and cooperating with said gate to prevent air from exiting the channel and thereby blocking the flow of air through the second channel when the gyro is tilted from the erect by more than the second angle.
For a gyro of the type having a spinning rotor and means spinning therewith for providing a flow of air, an erection system characterized by:
- a base having a centrally disposed air inlet channel and plurality of channels formed in the base, each of which extends in a different direction and has an air inlet end communicating with the centrally disposed air inlet channel and an air outlet end;
- means associated with the gyro and the erection system for directing the flow of air through the channels;
- air flow control means arranged with the channels and effective for permitting air to flow through the channels when the gyro is erect, whereby the flow of air through the erection system is balanced and including balls arranged to roll in the channels for blocking the air inlet and outlet ends of the channels in accordance with the tilting of the gyro from the erect;
- a cover which fits over the base for maintaining the balls in the channels;
- the air flow control means being effective for blocking the flow of air through one of the channels when the gyro is tilted from the erect by more than a first relatively small predetermined angle and less than a second relatively large predetermined angle, whereupon the flow of air through the erection system is unbalanced, which provides a torque for erecting the gyro;
- and
- said air flow control means being effective for blocking the flow of air through another of the channels when the gyro is tilted from the erect by more than the second angle, with the unbalanced air flow being thereupon negated which renders the erection system disabled.
