专利汇可以提供Glider with automatically releasing foldable wings专利检索，专利查询，专利分析的服务。并且A toy glider with pivotally mounted wings movable from an extended, flight position to an overlapped, swept back, launch position is provided with axially movable weighted means for retaining the wings in the swept back position during launching against tension normally urging the wings toward the extended position and automatically releasing the wings to the extended position as the launched glider reaches a maximum altitude and noses down to begin its descent. The axially movable weighted means comprises an elongated rod suspended beneath the glider fuselage registering with means on the fuselage for limiting its back and forth movement, and having a concentrated weight attached thereto in general alignment with the extended wings. The amount and positioning of such concentrated weight influences the angle and range of the descent glide and means may be provided as by employing an axially adjustable weight for permitting the user to adjust and vary the flight characteristics of the glider.，下面是Glider with automatically releasing foldable wings专利的具体信息内容。
1. A toy glider comprising an elongated fuselage having pivotally mounted wings movable from an extended, flight position to an overlapped, swept back launch position, resilient means normally urging said wings to the extended flight position, an elongated rod extending parallel to and supported longitudinally of said fuselage, said rod having a concentrated weight thereon in substantial alignment with the extended wings, stop means at forward and rear portions of said fuselage for providing limited longitudinal movement of said rod and weight, and loop means at the outer trailing edges of said wings slidably engageable by said rod in the rearmost position thereof for supporting said wings in the swept back, launch position against the action of said resilient means.
2. A toy glider as defined in claim 1 wherein the concentrated weight on said rod includes means for moving the weight center thereof longitudinally of said rod.
3. A toy glider as defined in claim 2 wherein said last named means comprises an externally threaded member coaxially mounted on said rod and an internally threaded, weighted member in coaxial engagement with said first member to provide longitudinal movement thereof when rotated with respect to said first member.
4. A toy glider as defined in claim 1 wherein the foldable wings are pivotally mounted toward the forward end of said fuselage, and said forward end includes laterally extending means substantially perpendicular to the center line of said fuselage forming stop members aligning said wings in the extended, flight position thereof.
5. A toy glider as defined in claim 4 wherein the pivot mounting of said wings comprises parallel pivot axes and means for positioning the wings with respect to said axes so that the planes of said wings are sufficiently offset to perMit free overlap of the wings when moved to the swept back, launch position.
6. A toy glider as defined in claim 4 wherein said resilient means extend from points on the leading edges of said wings, outwardly spaced from the pivot mounting thereof, to a point forwardly of said pivot mounting and above the plane of said wings.
7. A toy glider as defined in claim 6 wherein said resilient means comprising a longitudinally yieldable strand member passing through a transverse aperture in the plane and having ends thereof secured to leading edges of said wings.
8. A toy glider as defined in claim 7 wherein the location of said aperture is such that in the swept back, launch position of said wings said resilient means, as extended, lies outwardly of the pivot mountings of said wings.
9. A toy glider comprising an elongated fuselage having a tail assemblage at one end and an enlarged and elongated nose portion at the other end thereof means at the juncture of said fuselage and nose portion for pivotally mounting wings beneath said fuselage for movement from extended, flight position to a swept back, launch position, means suspending an elongated rod beneath said fuselage and wings in alignment with said fuselage, and in a manner to have limited longitudinal movement with respect to said fuselage, said rod carrying a concentrated weight at a point in substantial alignment with said wings, resilient means extending from points on the leading edges of said wings outwardly of the pivot mounting thereof to a point in said nose portion forwardly of said pivot mounting for normally urging said wings to extended, flight position, and means at the outer trailing edges of said wings engageable by said rod in the rearwardly oriented position thereof for supporting the wings in the swept back, launch position, said last named means being automatically disengaged to permit extension of the wings to flight position when said rod is moved by said weight to a forwardly oriented position.
10. A toy glider as defined in claim 9 wherein said resilient means engages said nose section at a point somewhat above the plane of said wings.
11. A toy glider as defined in claim 9 wherein the concentrated weight on said rod includes means for moving the weight center thereof longitudinally of said rod.
12. A toy glider with pivotally mounted wings movable from an extended, flight position to a swept back, launch position, said glider comprising an elongated fuselage terminating at one end in a tail assemblage and at the other end in an enlarged and streamlined nose and wing mounting assemblage, the nose portion of said assemblage having a transverse dimension two or three times greater than said fuselage and including at the rear portion thereof an essentially flat surface extending downwardly from and perpendicularly to said fuselage, laterally extending vanes of generally triangular contour projecting from opposed sides of said nose portion having swept back leading edges and following edges in common alignment with said perpendicularly disposed surface of the nose portion providing wing stops for the extended wing position, other transversely protruding means at opposed sides of said nose portion above and extending rearwardly from said perpendicularly disposed surface thereof, pivotally supporting wings for swinging movement beneath said fuselage, axially aligned means in said nose section and in substantial alignment with said tail assemblage for supporting beneath said wings and parallel to said fuselage an axially moveable lightweight rod having a concentrated weight in substantial alignment with said wings, restraining means on the rear trailing edges of said wings engageable by said rod in the rearwardly oriented position thereof, and resilient means extending from a forward portion of said nose section to points on the leading edges of said wings outwardly spaced from the pivot mounting thereof for urging said wings to the extended, flight position when forward movement of said rod has dIsengaged said restraining means.
13. A toy glider as defined in claim 12 wherein said resilient means engages said forward portion of the nose section at a point somewhat above the plane of said wings.
14. A toy glider as defined in claim 12 wherein the concentrated weight on said rod includes means for moving the weight center thereof longitudinally of said rod.
