Abstract

Abstract A balloon package is folded onto an ejection platform which becomes propelled outwardly from an enclosure. A gas cartridge inflates the balloon as the latter is ejected from the enclosure causing the balloon''s inflation. A radio transmitter attached to the balloon is actuated when the balloon is ejected so that a coded radio signal can issue forth from the location of the balloon. Manual and automatic trigger means are provided for ejecting the balloon.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 165 words
A signal device stored in a housing and comprising a visual indicator, means for propelling the indicator to a point removed from the housing, means responsive to indicator displacement for maintaining the indicator in an area removed from the housing, the propelling means comprising a spring member disposed between the indicator and a supporting base, hold-down means normally restraining the indicator against the spring member, trigger means for releasing the hold-down means thereby allowing the spring means to propel the indicator outwardly from the housing, support means supporting the base to allow movement of the base relative to the housing, the trigger means comprising a member projecting from the housing for rotating a first pivotally mounted section of the hold-down means from engagement with the indicator when the base moves, and means connected between a second pivotally mounted section of the hold-down means and the housing for rotating the second hold-down section free from engagement with the indicator thereby allowing propulsion thereof from the housing.
Claim 2
Dependent Claim 165 words
A signal device stored in a housing and comprising a visual indicator, means for propelling the indicator to a point removed from the housing, means responsive to indicator displacement for maintaining the indicator in an area removed from the housing, the propelling means comprising a spring member disposed between the indicator and a supporting base, hold-down means normally restraining the indicator against the spring member, trigger means for releasing the hold-down means thereby allowing the spring means to propel the indicator outwardly from the housing, support means supporting the base to allow movement of the base relative to the housing, the trigger means comprising a member projecting from the housing for rotating a first pivotally mounted section of the hold-down means from engagement with the indicator when the base moves, and means connected between a second pivotally mounted section of the hold-down means and the housing for rotating the second hold-down section free from engagement with the indicator thereby allowing propulsion thereof from the housing.
Claim 3
Dependent Claim 224 words
A signal device stored in a housing and comprising a visual indicator, means for propelling the indicator to a point removed from the housing, means responsive to indicator displacement for maintaining the indicator in an area removed from the housing, the propelling means comprising spring member disposed between the indicator and a supporting base, hold-down means normally restraining the indicator against the spring member, trigger means for releasing the hold-down means thereby allowing the spring means to propel the indicator outwardly from the housing, the trigger means comprising cam means connected to the hold-down means through linkage members and a trigger member for displacing the cam means thereby causing displacement of the linkage members which results in disengagement between the hold-down means and the indIcator followed by propulsion thereof from the housing, support means supporting the base to allow movement of the base along a preselected path relative to the housing, second trigger means independent from the first trigger means are provided comprising a member projecting from the housing for rotating a first pivotally mounted section of the hold-down means from engagement with the indicator when the base moves, and means connected between a second pivotally mounted section of the hold-down means and the housing for rotating the second hold-down section free from engagement with the indicator thereby allowing propulsion thereof from the housing.
Claim 4
Dependent Claim 224 words
A signal device stored in a housing and comprising a visual indicator, means for propelling the indicator to a point removed from the housing, means responsive to indicator displacement for maintaining the indicator in an area removed from the housing, the propelling means comprising spring member disposed between the indicator and a supporting base, hold-down means normally restraining the indicator against the spring member, trigger means for releasing the hold-down means thereby allowing the spring means to propel the indicator outwardly from the housing, the trigger means comprising cam means connected to the hold-down means through linkage members and a trigger member for displacing the cam means thereby causing displacement of the linkage members which results in disengagement between the hold-down means and the indIcator followed by propulsion thereof from the housing, support means supporting the base to allow movement of the base along a preselected path relative to the housing, second trigger means independent from the first trigger means are provided comprising a member projecting from the housing for rotating a first pivotally mounted section of the hold-down means from engagement with the indicator when the base moves, and means connected between a second pivotally mounted section of the hold-down means and the housing for rotating the second hold-down section free from engagement with the indicator thereby allowing propulsion thereof from the housing.
