Welch ABSTRACT: A rectangular board, a pivot at one corner thereof joumaling an arm carrying at the free end thereof a toy airplane thus having a 90 segment of takeoff and landing space on said board, a unitary control and throttle lever based on said board, and a source of electric power for operation of the motor and propeller of the plane.

PATENTEI] JAN 1 9 l97l SHEET 1 OF 2 10v AIRPLANE ASSEMBLY BACKGROUND OF THE INVENTION The invention relates to a motor-driven captive airplane operable about a pylon mounted on a board. Devices in the prior art involving captive airplanes have had the necessity for balance weights. The present plane is airborne by the propeller driven by an electric motor and the rudder elevator control.

The present invention has for its object to provide a motordrivencaptive airplane rotatable about a pylon on one comer of a board a portion of which constitutes a 90 takeoff and landing space.

BRIEF DESCRIPTION OF THE DRAWING:

FIG. I is a view in perspective of a captive airplane assembly embodying the invention.

FIG. 2 is an enlarged view in vertical cross section of the pylon and the control and accelerator lever mounted in the board.

FIG. 3 is a plan view of the plane showing the electric wire and the rudder elevator control wire in broken lines.

FIG. 4 is a side view in elevation of the plane.

FIG. 5 is a cross-sectional slipring connection to the plane.

Referring more particularly to the drawing, the numeral refers to the base of the device, provided adjacent one corner 11, with the pylon or standard 12, which latter has an enlarged portion at 13. An angular swivel element 14 is freely retained on portion 13 by means of the rings 15 and 16. Within the top of the standard 12 is a vertically reciprocable pushpull element 17 connected with the rudder elevator means 18, and a rotatable element 19 provided with sliprings 20 in contact with brushes 2! for supplying electrical current. The horizontal portion 22 of the swivel element 14 is connected to the tubular arm 23 by the pin 24 horizontally disposed in portion 22.

The opposite end of the tubular arm 23 with a push-pull and slipring element 25 housed in a nascelle of the near wing 27 of the plane 30.

A control handle 31 is pivoted in a trunnion 32 mounted on the base 10. The lower end 33 of handle 31 is secured to the pull wire 34, which is fastened by its opposite end to the pushpull element 17, which latter is connected by a similar wire 35 to the push pull element 25 on the plane. The element 25 is wired through the plane to rudder elevator 36.

Electric power enters the assembly through a transformer 40, to reduce the voltage, thence into the rheostat 41 in the control handle 31. The accelerator button 42 governs the current fed to the motor 43 connected with propeller 44.

It will be understood that the control handle will regulate both the speed of the motor and the action of the rudder elevator 36.

I claim:

1. A toy airplane assembly including a base board, a standard adjacent comer thereof, a tubular elbow element pivoted on said standard, a tubular arm extending transversely of the board pivoted on a horizontal axis to said elbow, a toy plane connected laterally with the free end of said tubular arm, an electric motor driven propeller on said plane, a pivoted elevator rudder on said plane, a control lever mounted on said board for limited movement about a horizontal axis, a pushpull accelerator element slidably axially disposed in said handle, means connecting the control handle with the elevator rudder, and an electrical circuit connecting the accelerator element with the propeller motor.

Claims

1. A toy airplane assembly including a base board, a standard adjacent corner thereof, a tubular elbow element pivoted on said standard, a tubular arm extending transversely of the board pivoted on a horizontal axis to said elbow, a toy plane connected laterally with the free end of said tubular arm, an electric motor driven propeller on said plane, a pivoted elevator rudder on said plane, a control lever mounted on said board for limited movement about a horizontal axis, a push-pull acceleratOr element slidably axially disposed in said handle, means connecting the control handle with the elevator rudder, and an electrical circuit connecting the accelerator element with the propeller motor.
