Abstract
Abstract A wind actuated rotatable tubular device comprising a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof with rigid rods secured to said tubular member to define the inlet and outlet openings and with a blade-like member secured across at least one of said openings. A flexible line is attached to the rods at the inlet opening centrally of said opening with the opposite end of the flexible line attached to an anchoring member so that the wind passing through the tubular member will strike and impinge against the blade-like member to cause the tubular member to rotate with respect to the anchoring member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rods which are detachably secured to said tubular member, said rods at said outlet end having a plurality of generally flat blade-like members secured thereto, said rods at said inlet end being connected to each other and said rods at said outlet end being connected to each other, each of said rods having stop means positioned adjacent its opposite ends but spaced from the ends of respective rods to provide tips on said rods which tips fit in openings in said tubular member for holding said tubular member in expanded or extended position, means for attaching said tubular member to an anchoring member so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said anchoring member.
Claim 2
Dependent Claim
180 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rods which are detachably secured to said tubular member, said rods at said outlet end having a plurality of generally flat blade-like members secured thereto, said rods at said inlet end being connected to each other and said rods at said outlet end being connected to each other, each of said rods having stop means positioned adjacent its opposite ends but spaced from the ends of respective rods to provide tips on said rods which tips fit in openings in said tubular member for holding said tubular member in expanded or extended position, means for attaching said tubular member to an anchoring member so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said anchoring member.
Claim 3
Dependent Claim
138 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rods which are detachably secured to said tubular member, said rods at said outlet opening having a blade-like member, a flexible line attached to said rods at said inlet opening and detachably secured to a kite line of a kite in flight to hold said device in spaced relation to a kite in flight, swivel means connected to said flexible line so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said kite line.
Claim 4
Dependent Claim
138 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rods which are detachably secured to said tubular member, said rods at said outlet opening having a blade-like member, a flexible line attached to said rods at said inlet opening and detachably secured to a kite line of a kite in flight to hold said device in spaced relation to a kite in flight, swivel means connected to said flexible line so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said kite line.
Claim 5
Dependent Claim
181 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rigid rods which are detachably secured to said tubular member, said rigid rods spanning said inlet and outlet openings, with said rigid rods at said inlet and outlet openings being connected respectively to each other only through said tubular member, said rigid rods at at least one of said inlet and outlet openings having a blade-like member, a flexible line attached to said rigid rods at said inlet opening centrally of said inlet opening with said flexible line secured to a kite line of a kite in flight to hold said device in spaced relation to a kite in flight so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said kite line through said flexible line.
Claim 6
Dependent Claim
181 words
A knock-down wind actuated rotatable tubular device comprising, a generally tubular member formed of a collapsible and flexible material having an inlet opening at one end and an outlet opening at the other end thereof, rigid means defining said inlet and outlet openings, said rigid means comprising rigid rods which are detachably secured to said tubular member, said rigid rods spanning said inlet and outlet openings, with said rigid rods at said inlet and outlet openings being connected respectively to each other only through said tubular member, said rigid rods at at least one of said inlet and outlet openings having a blade-like member, a flexible line attached to said rigid rods at said inlet opening centrally of said inlet opening with said flexible line secured to a kite line of a kite in flight to hold said device in spaced relation to a kite in flight so that the wind passing through said tubular member will strike and impinge against said blade-like member to cause said tubular member to rotate with respect to said kite line through said flexible line.
Claim 7
Dependent Claim
79 words
A device as set forth in claim 3 in which the rods at the inlet end are connected to each other and the rods at the outlet end are connected to each other and each of the rods has stop means positioned adjacent its opposite ends but spaced from the ends of respective rods to provide tips on said rods which tips fit in openings in the tubular member for holding said tubular member in expanded or extended position.
Claim 8
Dependent Claim
24 words
A device as set forth in claim 3 in which a portion of said flexible line is positioned within a substantially rigid sleeve member.
Claim 9
Dependent Claim
48 words
A device as set forth in claim 3 in which a clip is secured to one end of the flexible line with said clip having a slot whereby it is slipped on to the kite line to hold said clip in fixed position relative to the kite line.
