Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
Launch support apparatus for a gas powered missile device, said apparatus comprising: a cylindrically shaped, hollow launch tube including first and second open end portions; a front cover detachably enclosing said first end portion of said tube; and means including a rear cover detachably engaging the launch tube for directing a pressure wave generated by said device against said front cover to separate said front cover from said tube and thereby prevent direct contact between said front cover and said device as said device exits through said first opening.
Claim 2
Dependent Claim
89 words
Launch support apparatus for a gas powered missile device, said apparatus comprising: a cylindrically shaped, hollow launch tube including first and second open end portions; a front cover detachably enclosing said first end portion of said tube; and means including a rear cover detachably engaging the launch tube for directing a pressure wave generated by said device against said front cover to separate said front cover from said tube and thereby prevent direct contact between said front cover and said device as said device exits through said first opening.
Claim 3
Dependent Claim
35 words
An apparatus according to claim 1, wherein said means comprises a rear cover member detachably engaging the second end portion of said tube and positioned in a direct exhaust path of said gas powered device.
Claim 4
Dependent Claim
101 words
Launch support apparatus for a gas powered missile device, said apparatus comprising: a cylindrically shaped, hollow launch tube including first and second open end portions; a front cover member detachably enclosing the first end portion of said tube; means including a rear cover detachably engaging the launch tube for directing a pressure wave generated by said device against said front cover to separate said front cover from contact with said tube; and guide means engaging said front cover and said tube to force said front cover to move along a trajectory deviating from a longitudinal axis extending through said launch tube.
Claim 5
Dependent Claim
101 words
Launch support apparatus for a gas powered missile device, said apparatus comprising: a cylindrically shaped, hollow launch tube including first and second open end portions; a front cover member detachably enclosing the first end portion of said tube; means including a rear cover detachably engaging the launch tube for directing a pressure wave generated by said device against said front cover to separate said front cover from contact with said tube; and guide means engaging said front cover and said tube to force said front cover to move along a trajectory deviating from a longitudinal axis extending through said launch tube.
Claim 6
Dependent Claim
34 words
An apparatus according to claim 3, wherein said means comprises a rear cover detachably engaging the second end portion of said tube and positioned in a direct exhaust path of said gas powered device.
Claim 7
Dependent Claim
61 words
An apparatus according to claim 3, wherein said guide means comprises a bifurcated hook member including a first end portion pivotally attached to a central boss portion formed on said front cover and extending into said launch tube, said hook member further including a claw shaped end portion pivotally engaging a recess formed in an inner wall surface of said tube.
Claim 8
Dependent Claim
41 words
An apparatus according to claim 5, wherein said claw portion of said hook member rotates within said recess as said front cover initially separates from said tube forcing said front cover to move in a trajectory deviating from said longitudinal axis.
Claim 9
Dependent Claim
32 words
An apparatus according to claim 6, wherein said hook member rotates a certain degree and then detaches from said tube with said front cover continuing in a path deviating from said axis.
