Abstract
Abstract A toy which is entertaining and educational in that the toy may be used to teach basic principles of landing an airplane. A model airplane having a pair of supports is slidingly supported on a monofilament support line. One end of the support line is secured to a fixed vertical support, and the other end is attached to a universally movable vertical support, which is modeled after a joystick. A landing surface is positioned below the support line. The model joystick is utilized to regulate the tautness of the support line in order to control the rate of vertical movement of the model airplane.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
104 words
A toy comprising, in combination, a support line having one end fixed at a given height, a vehicle having a support movably engaging the support line and being supported thereby, a movable vertical support connected to the other end of the support line at a second given height for adjusting the slack of the support line to regulate the rate of descent of the vehicle along the support line, and a landing surface positioned below a portion of the support line engageable with the vehicle, whereby manipulation of the movable vertical support provides a control for the rate of vertical movement of the vehicle.
Claim 2
Dependent Claim
104 words
A toy comprising, in combination, a support line having one end fixed at a given height, a vehicle having a support movably engaging the support line and being supported thereby, a movable vertical support connected to the other end of the support line at a second given height for adjusting the slack of the support line to regulate the rate of descent of the vehicle along the support line, and a landing surface positioned below a portion of the support line engageable with the vehicle, whereby manipulation of the movable vertical support provides a control for the rate of vertical movement of the vehicle.
Claim 3
Dependent Claim
15 words
A toy as defined in claim 1 wherein the support line is a monofilament line.
Claim 4
Dependent Claim
24 words
A toy as defined in claim 2 wherein the vehicle support is a pair of longitudinally spaced wire hooks engageable with the monofilament line.
Claim 5
Dependent Claim
26 words
A toy as defined in claim 3 wherein the diameter of the wire of the hooks is not less than the diameter of the monofilament line.
Claim 6
Dependent Claim
87 words
A toy as defined in claim 4 including a fixed vertical support connected to the one end of the support line, said one end of the support line being spaced horizontally from the movable vertical support a distance 10 times greater than the difference in height between the one end of the support line and the other end of the support line, and a vehicle catch mounted on the vertical support and engageable with the vehicle to hold releasably the vehicle adjacent to the fixed vertical support.
Claim 7
Dependent Claim
60 words
A toy as defined in claim 1 including, a fixed vertical support connected to one end of the support line, a vehicle catch mounted on the vertical support and engageable with the vehicle to hold releasably the vehicle adjacent to the fixed vehicle support, and an arrester mounted on the landing surface engageable with the vehicle to stop the vehicle.
Claim 8
Dependent Claim
70 words
A toy as defined in claim 1 including, a fixed vertical support connected to the one end of the support line and a vehicle catch mounted on the vertical support and engageable with the vehicle to hold releasably the vehicle adjacent to the fixed vertical support, whereby the vehicle is releasable from the vehicle catch by movement of the movable vertical support to increase the tautness of the support line.
Claim 9
Dependent Claim
23 words
A toy as defined in claim 1 including an arrester mounted on the landing surface engageable with the vehicle to stop the vehicle.
Claim 10
Dependent Claim
49 words
A toy as defined in claim 1 including an obstacle positioned below the support line adjacent to the landing surface in the path of the vehicle, whereby the movable vertical support must be appropriately adjusted to raise the vehicle over the obstacle prior to engagement with the landing surface.
Claim 11
Dependent Claim
94 words
A toy as defined in claim 1 including, a fixed vertical support connected to one end of the support line, a vehicle catch mounted on the vertical support and engageable with the vehicle to hold releasably the vehicle adjacent to the fixed vertical support, and an obstacle positioned below the support line and between the end of the landing surface and the fixed vertical support, whereby the movable vertical support must be appropriately adjusted during the descent of the vehicle to raise the vehicle over the obstacle prior to engagement with the landing surface.
