CI. 46-15 Claims ABSTRACT OF THE DISCLOSURE A toy device for simulating the attitudes of a vehicle in flight. The device comprises a cockpit structure for accommodating at least one child, the device employing a base structure having a curved bottom surface which permits the child to position the cockpit in any attitude of elevation (i.e., level flight, ascent or descent) within the limits of the curved bottom surface. A second embodiment of the invention further includes means for suspending the cockpit in a manner to permit rotation thereof about a longitudinal axis of the cockpit that is inclined from the front to the rear of the cockpit. The curved base structure and the rotation about the inclined axis permits the cockpit to assume the three basic attitudes of a vehicle in flight, namely, elevating, turning and banking.
BACKGROUND OF THE INVENTION The present invention relates generally to a toy vehicle device, and particularly to a toy airplane capable of accommodating at least one child, and in which the child can operate the toy in the manner of an airplane or space vehicle in flight. This is accomplished in a safe, simple and easy manner without the use of arm-foot controls which require arm-foot coordination, without costly power assist means and with a control arrangement that will not permit the toy to turn completely over and dump the child onto the floor. Further, the toy is economical and simple to build and manufacture.
BRIEF SUMMARY OF THE INVENTION Broadly, the above operation and advantages are accomplished by use of a body structure, including a cockpit for accommodating a child, the body structure having a base portion provided with a curved bottom surface for resting on a smooth horizontal surface of a base plate. A control arm is pivotally attached to the body structure and to the base plate, and extends into the cockpit for operation by the child. By a forward thrust or a rearward pull on the control arm the child can position the body structure and cockpit in any descending or climbing attitude (within the limits of the curved bottom surface of the base portion) as well as a level flight position by intermediate positioning of the control arm.
In a second embodiment of the invention, a cockpit structure is suspended for rotation along a longitudinal axis that is inclined from the front to the rear of the cockpit, the plane of the axis extending above the center of gravity of the cockpit. The control arm is mechanically connected to the cockpit in a manner to effect rotation thereof about the inclined axis. The rotation provides a banking attitude for the cockpit and for the child contained therein. Because of the axis being inclined from front to rear and extending above the center of gravity of cockpit, the cockpit also turns in the direction of the bank thereby providing a third basic attitude of flight (turning) while using the same basic motion for banking, namely, that of rotation. Thus, the structure of the second embodiment provides three basic attitudes of flight using only the two simple motions provided by (1) the curved base structure and by (2) the rotational movement of cockpit about its inclined axis.
THE DRAWINGS The invention, along with its advantages and objectives, will be more apparent from consideration of the following detailed description and the accompanying drawings in which:

FIG. 2 is a side diagrammatic view of a second embodiment of the invention;
FIG. 3 is a front end view of the embodiment shown in FIG. 2;
FIG. 4 is a perspective view of a control arrangement for the embodiment shown in FIGS. 2 and 3; and
FIGS. 5 and 6 are perspective views of the second embodiment showing simultaneous turning and banking attitudes of flight.
PREFERRED EMBODIMENTS OF THE INVENTION Specifically, the three FIGS. 1a to c show diagrammatically a toy airplane or toy space capsule device 10 in which a child can be accommodated to control and position the device in the manner indicated by the three figures. More particularly, the airplane or capsule comprises a cockpit structure 12 shown with a seat 14 (for seating the child therein), and a control arm 16 extending within the cockpit and to a position in'front of the seat. The bottom portion of the cockpit is provided with a rocker surface 18 curved in the longitudinal direction of the cockpit. The curved rocker surface rests on the flat horizontal surface of a base plate 20.
The cockpit structure 12 and seat 14 can be made from any suitable rigid material, for example, plywood, plastic, sheet metal or the like sufliciently durable for toy purposes. The curved bottom 18 need only support the weight of the structure and that of the child or children seated therein, and may be made in any suitable manner, for example, as shown in the succeeding figures presently to be described.
Similarly, the base plate 20 may be any structure capable of providing a substantially smooth, planar surface for the curved or rocker surface 18.
The lower end of the control arm 16 has a forward extension 21 pivotally attached to the cockpit at 22 while the lower end of the arm is attached to a link means 24- at 25. The link means is further pivotally attached to the plate 20 at 26. Any means or hardware suitable for the purposes of the toy can be used to attach the arm and link in the manner shown. A slotted opening (not shown) is provided in the curved bottom 18 of cockpit for accommodating the link 24 and the pivot means 26.
The cockpit 12 of the embodiment shown in FIGS. 10: to 0 can be made to assume any attitude of elevation by a simple forward thrust (FIG. lb) or rearward pull (FIG. 10) of the control arm 16 by the child (not shown) operating the toy. [The term elevation, as used herein, describes simply the three forward attitudes of flight, namely, descending, ascending (climbing) and level flight] Specifically, when the child pushes forward on the control arm 16, the bottom end of the arm operates about the pivots 22 and 25 to force the cockpit 12 to roll forward on its curved bottom surface 18 so that the cockpit assumes a descending attitude of flight as shown in FIG. 1b.
For the cockpit .to assume a climbing or ascending position of flight, the child simply pulls back on the control arm 12, the bottom forward extension 21 of the 3 arm forcing the cockpit to roll back on its curved bottom portion 18.
For level flight, the control arm is simply moved to an intermediate position as shown in FIG. 1a.
As can be readily appreciated from the diagrammatic views of FIGS. la to c, a simple aircraft or space capsule toy is provided requiring only a minimum number of inexpensive parts. Further, the toy is safe, there being nothing in the way of electrical power or mechanical assists (motors, gears, or hydraulics) to harm the child. Rather, a simple control arm 16 provides the child with all the power and leverage he needs to operate the toy.
FIGS. 2 to 6 are views of a second embodiment of the invention in which banking and turning attitudes of flight can be provided for a toy, or added to the toy described above in connection with FIGS. la to c.
More particularly, in the second embodiment of the invention, a cockpit structure is suspended for rotation about an inclined axis 31 by a bracket 32 located between the front wall 33 of the cockpit and a vertical support structure 34, and a pivot pin 36 extending between the rear wall of the cockpit and a second vertical support structure 38, the two vertical structures supporting the cockpit above a platform 40. The backet 32 is rigidly attached to both the wall 33 and the vertical support 34 and, as best seen in the view of FIG. 2, is lower than the rear pin 34 so that the axis 31 is inclined for the front to the rear of the cockpit.
It will be noted further, from the view of FIG. 2, that the inclined axis 31 extends through the cockpit 30 above its center of gravity CG.
The vertical support structures 34 and 38 are provided respectively with stabilizing ribs 42 and 44 to stablize the support structures and thereby provide longitudinal stability for the cockpit structure 30.
The platform is supported on and fixed to a pair of rocker members 46 (FIG. 3) curved in the direction of flight and shown resting on the upwardly facing, planar surface of a second platform or plate structure 48 for location on a floor or the ground.
To control the cockpit 30 in a manner similar to that described above in connection with FIGS. 1a to c, a wheel 50 attached to one end of a control shaft 52 extending into the cockpit is provided, the shaft extending from the cockpit to an L-shape arm 54 pivoted adjacent its center to a support structure 56 attached to the front stabilizing rib 42. The support structure 56 extends forwardly of the rib 42, and, as seen in the perspective view of FIG. 4, the L-shaped arm is spaced from its support 56 by a circular spacer or washer 57 so that the lower portion of the arm, which extends to one side of the rib 42, is clear thereof for movement about the pivot of the arm.
The lower portion of the arm 54 is pivotally connected to one end of an elongated stick or bar 58 extending through the platform 40, the other end of the bar being pivotally attached to the plate 48 by a suitable bracket 59. A slotted opening 60 is provided in the platform to accommodate the bar extending therethrough.
The control shaft 52 is pivotally linked to the upper end portion of the L-shaped arm 54 by a Yshaped bracket 61 and a universal attaching means 62. The arms of the Y extend along opposite sides of the universal means, and are pivotally connected or linked to a fixed center portion thereof in such a manner that the shaft 52 can rotate about its longitudinal axis while simultaneously being positively attached to the arm 54 which cannot ratates with the shaft.
As best seen in FIG. 4, the shaft 52 extends through the vertical support structure 34 through a bushing 64 supported in a corresponding opening in the support structure.
Between the vertical support 34 and the cockpit 30, the shaft 52 extends axially through the backet 32 and through the front wall 33 of the cockpit. The portion of the shaft near the center of the bracket has a pulley 66 mounted thereon in such a manner that the pulley is forced to rotate with rotation of the shaft yet the shaft is free to slide through the pulley along the axes of the pulley and shaft. This can be accomplished by a feathered key, for example, in which a key in the shaft and a mating keyway in the pulley has a clearance suitable to allow easy sliding of the shaft through the pulley. A similar result can be accomplished with a splined shaft.
In order to make the movement of the shaft as easy as possible, flat portions can be provided on opposed sides thereof, and rollers mounted in or on the pulley in engagement with the flat portions. With translation of the shaft through the pulley, the rollers roll on the fiat portions. With rotation of the shaft, the pulley and rollers rotate therewith.
Directly beneath the pulley 66 and the bracket 32 are two axially aligned pulleys 68 attached to the wall 33 of the cockpit 30 for rotation about their aligned axes. The center portion of a cable or rope 69 is located on the pulley 66 and properly seated in an accommodating groove in the pulley. From each side of the pulley, the rope extends down to and around the two pulleys 68 as the two ends thereof extend outwardly from the pulleys 68 to two tab means 70 and 71 fixed respectively on the left and right lower sides of the cockpit. In the figures, the bracket 70 is visible only in FIG. 3. The two ends of the rope are respectively suitably tied or otherwise fixed to the two tabs.
To cover the above-described components located forwardly of front wall 33 of the cockpit 30, a nose cone or cover 72 can be suitably attached to the front of the cockpit as seen in FIGS. 5 and 6, and as shown in phantom outline in FIG. 2.
In the operation of the toy airplane or capsule as described in connection with FIGS. 2 to 6, a child (not shown) is seated in the cockpit 30 behind the wheel 50. The child, by pulling back on the wheel and the shaft 52, rotates the L-shaped arm 54 about its pivot which rolls the platform 40 back on its curve rockers 46 by virtue the upper force directed upon the arm support 56. In this manner, the cockpit assumes a climbing position such as that shown in FIG. 2.
In a similar manner, by thrusting the shaft 52 forward, the L-shaped arm 54 pivots about its center portion in a manner to lower the nose of the airplane to a descending flight position on rockers 46, the L-shaped arm also pivoting at the point of its attachment to the bar 58. A stop means 74 (FIG. 2) is shown located between the platforms 40 and 48 to prevent the cockpit from assuming too steep a position. In changing the attitudes of elevation, the platform 40 is free to move along the bar 58 by virtue of the slotted opening 60 in the platform.
For the child to turn and bank the cockpit 30, he or she merely rotates the wheel 50 which rotates the pulley 66 about its axis. With rotation of the pulley, the cable or rope 69 is translated thereabout and about the pulleys 68 to translate the cockpit about the axes ofthe bracket 32 and rear pivot pin 36, and thus about the inclined axis 31. The rope rotates the cockpit by pulling the lower portron of the cockpit in the direction opposite to the bank, one end of the line shortening as the other end lengthens as shown in dashed outline in FIG. 3. By turning the wheel and shaft, the child can bank the cockpit left or right while the cockpit is simultaneously positioned in any attitude of elevation provided by a rearward pull or a forward thrust of the wheel and shaft as explained above.
However, because of the inclined axis 31 of rotation for the cockpit 30 extending above the center of gravity CG of the cockpit (see FIG. 2), the cockpit (and the child therein) actually turns in the direction of the bank, as seen in FIGS. 5 and 6. Thus, with a single, basic movement (i.e., the movement of rotation about the inclined axis), the air plane device of the present invention provides two basic attitudes of flight, namely, banking and turning. And, with the provision of the rockers 46 (with the means 54, 56 and 58 linking the shaft 52 to the platforms 40 and 48) a third basic attitude of flight is provided using the basic motion provided by the curved surfaces of the rockers on a planar surface.
In order to prevent the cockpit and rockers from walking off the platform or 48 with a rocking motion of the toy, two notched, angle plates '76 are shown suitably attached to the platform 48 adjacent the periph eral center of each rocker 46, and two rollers 77, respectively attached to the rockers, are disposed to seat respectively in the notches of the angle plates. In this manner, the toy vehicles, as described above, are free to rock about the rollers and angle plates without moving off the platform '20 or 48. The invention, however, is not limited to such means. Other devices may be used to prevent the toy structure from moving off its platform.
From the foregoing description, it should now be apparent that a new and useful toy structure has been disclosed, the operation of which is simple and safe. Further, the structure is essentially economical to build and manufacture. By use of a minimum number of relatively inexpensive components, the present invention provides an airplane or space capsule toy in which a child can be accommodated to operate the toy to assume attitudes of elevation (in the first embodiment of the invention), or to provide banking, turning and elevating attitudes (in the second embodiment) using only two basic motions of (1) rotation about an inclined longitudinal axis of a cockpit structure, and (2) the motion provided by a curved bottom or rocker surface operatively associated with the cockpit. No third pivoting structure is needed to provide the airplane of the invention with a turning function in a horizontal plane. And, as explained earlier, no costly and possibly unsafe power assists are provided or needed since the user can fully operate the toy with the simple use of his hands.
Though the invention has been described with a certain degree of particularity, changes may be made therein without departing from the spirit and scope thereof.
