Description
SPECIFICATION
Improvements in or relating to toy vehicles
This invention relates to improvements in or relating to toy vehicles, such as toy aeroplanes.
According to the present invention there is provided a toy vehicle, which comprises a body and a wheel axle which extends rotatably through the body, the wheel axle being pivotally movable with respect to the body so that, in use of the toy vehicle on a planar surface, the wheel axle pivots with respect to the body in a plane which intersects, but is not perpendicular to, the planar surface, whereby the toy vehicle turns and tilts alternately to the left and to the right.
Preferably, the toy vehicle comprises a toy aeroplane.
For a better understanding of the present invention, and to show how the same may be put into effect, reference will now be made, by way of example, to the accompanying drawings, in which:
Figures 1 to 3 inclusive are plan views of a toy aeroplane in accordance with the invention, showing the body of the toy aeroplane in respective different orientations relative to the wheel axle of the toy aeroplane,
Figures 4 to 6 inclusive are front views corresponding to Figures 1,2 and 3, respectively,
Figure 7 is an exploded perspective view of the toy aeroplane of Figures 1 to 6, and
Figure 8 is an exploded perspective view of a gear box of the toy aeroplane of Figures 1 to 7.
Referring now to the drawings, and, in particular, to Figure 7, a toy aeroplane comprises a main structural body or fuselage which is formed in two halves, a left half 42 and a right half 40. An elevator 41 extends through respective slots formed in the left and right halves of the fuselage and a cockpit 50 and an antenna 57 are secured in position by engagement between the left and right halves of the fuselage. The antenna 57 comprises flexible resilient polyvinyichloride (PVC). A wheel supporter 54 is provided with a planar projection which extends between the left and right halves of the fuselage in the assembled toy aeroplane and through which a metal screw 52 extends to secure the wheel supporter 54 to the right half 40 of the fuselage. A nose landing wheel 53 is rotatably mounted on the wheel supporter 54.A cylindircal iron balancing weight 56 is disposed inside the nose of the toy aeroplane and a light bulb 55 is disposed inside the cockpit 50. A single pole double throw switch 45 is secured underneath a tail portion of the toy aeroplane by engagement between the left and right halves of the fuselage, and each of the light bulb 55 and the switch 45 is provided with two wires 43, 44 for connecting the same to a source of electricity as will be described in detail hereinafter. The toy areoplane further comprises four jet propellers 48, a left propeller cover 49 and a right propeller cover 58, which are adhered or otherwise rigidly secured to the fuselage.The fuselage 40,42, the elevator 41, the jet propellers 48, the propeller covers 49, 58, the cockpit 50, the nose landing wheel 53 and the wheel supporter 54 are all made of rigid moulded polystyrene, the cockpit being translucent and the jet propellers 48 and the propeller covers 49, 58 being reflective.
A gear box is disposed within the fuselage and extends downwardly therefrom to define an undercarriage of the toy aeroplane. A wheel axle extends through the gear box 51 and is drivable in rotation on operation of the switch 45 to propel the toy aeroplane, as will be described hereinafter. Also, an upper portion of the gear box 51 is adapted to receive two batteries, as will be described hereinafter.
So that the toy aeroplane may be assembled, there is provided a plurality of metal screws. One screw (not shown) passes through a front portion of the gear box 51 and secures the same to the right half 40 of the fuselage. Another screw 47 passes through the left half 42 of the fuselage and through a projection formed at the rear of the gear box 51 to secure both to the right half 40 of the fuselage. A screw 46 is provided to a tail portion of the toy aeroplane to join the two halves of the fuselage and three further screws are also provided at front and intermediate portions of the toy aeroplane for the same purpose.
In the assembled toy aeroplane, the two halves of the fuselage define in an upper portion thereof an aperture through which two batteries may be inserted. This apertue is normally covered by wings 37 of the toy aeroplane. The wings 37 comprise rigid moulded polystyrene and are provided thereunder with left and right panels 59,60 which are adhered or otherwise rigidly secured to the upper portion of the wings 37. The wings 37 define an aperture therein through which extends a latching mechanism comprising a button 36 and a clip 38, both of which are made of rigid moulded polystyrene, and a metal screw 39 which secures the clip 38 to the button 36.
The latching mechanism can be moved using the button 36 to a "closed" position in which a rear portion of the clip 38 engages in a slot formed in a rear edge of the aperture defined in the upper portion of the fuselage. Also, a projection formed on the front edge of the wings 37 engages in a slot formed in the fuselage in front of the aperture. In order to insert batteries into the toy aeroplane, the latching mechanism is moved to an "open" position and the wings 37 are slid rearwardly to remove the same from the aperture.
Referring now to Figure 8, the gearbox 51 comprises a casing which is formed in two halves, a left half and a right half 1. A lightweight metal wheel axle 21 extends rotatably through the gear box casing and carries a left wheel 12 and a right wheel 33. The left wheel 12 is rigidly mounted to one end of the wheel axle 21 by means of a metal rivet or eyelet 13 which passes through the left wheel 12 and frictionally engages round the wheel axle 21.The right wheel 33 is rigidly mounted to the other end of the wheel axle 21 by means of a metal rivet or eyelet 30 which passes through right wheel 33 and frictionally engages round the axle 21, a metal washer 32 through which the eyelet 30 passes and which abuts the inner face of the right wheel 33 and a metal compression spring 31 surrrounding the eyelet 30 and disposed between the washer 32 and a flanged end portion of the eyelet 30, so that the right wheel 33 is biased towards the respective end of the wheel axle 21. The gear box casing 1, 11 and the right wheel 33 comprise a rigid, moulded acrilonitrile/butadiene/ styrene copolymer (ABS) and the right wheel 33 is provided with a flexible resilient PVC tyre 34. The left wheel 12 comprises rigid moulded polystyrene.
An upper portion of the gear box casing 1, 11 defines a battery housing containing indicators 35 which may, for example, comprise paper labels adhered to the gear box casing. A resilient copper series contact 4 is disposed in the battery housing at one end thereof and is secured in position by means of parallel slots defined in the right half 1 of the gear box casing, which slots engage opposed edge portions of the contact 4. A copper positive contact 29 is secured to the battery housing at the other end thereof by means of a metal eyelet or rivet 28 which passes through the positive contact 29 and through a hole formed in the right half 1 of the gear box casing, so that part of the positive contact 29 extends outside the gear box casing 1, 11 and part of the positive contact 29 extends resiliently into the battery housing.A copper negative contact 15 is secured to the battery housing adjacent the positive contact 29 by means of a metal eyelet or rivet 16 which passes through the negative contact 15 and through a hole formed in the left half 11 of the gear box casing, so that part of the negative contact 15 extends outside the gear box casing 1, 11 and part of the negative contact 15 extends resiliently into the battery housing. Thus, two batteries may be inserted into the battery housing as hereinbefore described and are then resiliently held in place by the contacts 4,29,15.
An electric DC motor 17 is supported by walls of the gear box casing 1, 11 and is connected in series with the batteries in the battery housing and the switch 45 by means of the positive and negative contacts 29, 15 and the two wires 43, 44 with which the switch 45 is provided. The light bulb 55 and a means for making the light bulb 55 flash are also connected in series with the batteries and the switch 45, as will be described in detail hereinafter.
In use, rotation of the drive shaft of the motor 17 is transmitted to the wheel axle 21 by means of a gear chain comprising a pinion 18, which is fixed on the drive shaft for rotation therewith, first, second, third and fourth gears 23,25,22 and 24, which are journalled in the gear box casing 1, 11, a crown gear 10 and a pinion 19 which is fixed on the wheel axle 21 for rotation therewith. The crown gear 10 comprises coaxial and integrally formed driving and driven wheels and is rotatably mounted on a mid portion of a wheel axle holder 20, which is journalled in the gear box casing 1, 11 and through which the wheel axle 21 rotatably and slidably extends. Each of the first, second, third and fourth gears 23, 25, 22 and 24 comprises a driving wheel and a driven wheel coaxially and integrally formed therewith.The motor pinion 18 meshes with the driving wheel of the first gear 23, the driven wheel of the first gear 23 meshes with the driving wheel of the second gear 25, the driven wheel of the second gear 25 meshes with the driving wheel of the third gear 22, and the driven wheel of the third gear 22 meshes with the driving wheel of the crown gear 10 and the driven wheel of the crown gear 10 meshes with the wheel axle pinion 19. The motor pinion 18, the gears 22,23,24 and 25, the crown gear 10, the wheel axle pinion 19 and the wheel axle holder 20 all comprise a tough abrasion resistant material. For example, the crown gear 10 and the wheel axle holder 20 comprise a rigid moulded acetal resin.A resilient flexible member 27, also comprising a moulded acetal resin, is secured to the interior of the gear box casing 1, 11 so as to be vibrated by contact with the rotating motor pinion 18. This produces a sound which simulates that of a jet aeroplane in flight.
In addition to the means described above for effecting rotation of the wheel axle 21 and thus propelling the toy aeroplane, there is provided a means for effecting limited rotation of the wheel axle holder 20 within the gear box casing, comprising the fourth gear 24, a worm gear 27 which is provided at one end with an integral driving wheel therefor, a lightweight conducting metal gear axle 8 which extends through and is fixed to the worm gear 7, the worm gear 7 and the gear axle 8 being journalled in the gear box casing 1, 11, a crank 6, which is also journalled in the gear box casing 1, 11 and which is provided with an integral driving wheel, and a guide member 9 which is secured to an end portion of the wheel axle holder 20 by means of cooperating portions of non-circular cross-section provided on the guide members 9 and the wheel axle holder 20 respectively.In use, the driven wheel of the third gear 22 meshes with the driving wheel of the fourth gear 24, the driven wheel of the fourth gear 24 meshes with the driving wheel of the worm gear 7, the worm of the worm gear7 meshes with the driving wheel of the crank 6, the crank 6 engages the guide member 9 and the guide member 9 effects limited rotation of the wheel axle holder 20 in alternating directions. Slots are provided in the gear box casing 1,11 to accommodate the associated turning of the wheel axle 21. The crank 6, the worm gear7 and the guide member 9 comprise a tough moulded acetal resin.
As can more clearly be seen in Figures 1 to 6 inclusive, when the switch 45 is closed and the toy aeroplane is placed on a smooth surface, the toy aeroplane is not only propelled along but also effects turning and tilting movements. Because the wheel axle 21 repeatedly turns in the clockwise and anticlockwise directions, the toy aeroplane repeatedly turns to the left and to the right. In addition, because the plane in which the wheel axle 21 moves is inclined with respect to the aeroplane body, and in particularwith respect to the plane containing the wings 37, the aeroplane body repeatedly tilts to the left and to the right. Thus, the toy aeroplane can simulate the movement of a jet aeroplane in flight.
Referring again to Figure 8, a means for making the light bulb 55 flash comprises a first resilient copper contact 5, which is secured within the gear box casing 1,11 by means of a metal eyelet or rivet 26 which passes through the contact 5 and through a hole in the gear box casing 1, 11, and a second resilient copper contact 3, which is seated in a slot formed in an inner wall of the gear box casing 1, 11.
The first contact 5 is connected to the light bulb 55 by one of the wires 43,44 with which the light bulb 55 is provided. The second contact 3 is connected by a wire 2 to the positive contact 29 of the battery housing. In addition, the other of the wires 43,44 with which the light bulb 55 is provided and one of the wires 43, 44 with which the switch 45 is provided are both connected to a first contact of the motor 17, the other of the wires 43,44 with which the switch 45 is provided is connected to the negative contact 15 of the battery housing and a second contact of the motor 17 is connected to the positive contact 29 of the battery housing.
The first contact 5 of the means for making the light bulb 55 flash resiliently contacts one end of the gear axle 8 and the second contact 3 resiliently contacts the gear axle 8 adjacent the other end thereof. During rotation of the gear axle 8, contact between the second contact 3 and the gear axle 8, is periodically broken, beacuse an extension of the worm gear 7, which comprises an insulating material, passes between the second contact 3 and the gear axle 8. Thus, the light bulb 55 flashes on and off once during each revolution of the gear axle 8.
In order that the gear box 51 may be assembled, three metal screws 14 are provided which pass through holes formed in the left half 11 of the gear box casing and engage in internally threaded projections formed on the inner face of the right half 1 of the gear box casing.
Thus, the toy aeroplane described and illustrated can imitate the movements of a jet aeroplane baking and turning alternately to the left and to the right and is provided with a flashing light in the cockpit. Means are also provided for making a noise imitating that of a jet engine.
