Description
SPECIFICATION
Toy vehicle
This invention relates to a toy vehicle such as a
toy motor car.
According to the invention, there is provided a toy
vehicle which comprises a first member adapted to
be moved across a surface, a second member,
which is reciprocably or pivotally connected to the
first member, and means for storing energy in
response to reciprocation or pivotal movement of
the second member with respect to the first
member.
One aspect of the invention provides a toy car of
simple construction in which energy is imparted to
and stored in an internal clockwork mechanism by
pushing down a frame of the car in order
subsequently to release the accumulated energy
from the clockwork mechanism for running the toy
car. Preferably, pushing the frame downwards
causes disengagement of a driving axle of the car
from the clockwork mechanism whilst the release of
the accumulated energy from the clockwork is
accompanied by disengagement thereof from means associated with the frame for winding up the
clockwork, such as a vertically movable rack.
A preferred toy motor car according to the
invention comprises a chassis, a frame pivotally
mounted on the chassis, a coil spring disposed
between the chassis and the frame for resiliently
biassing the same apart, and driving means for
imparting energy to an internal clockwork
mechanism through a rack by pushing the frame
down towards the chassis, the driving means
comprising a driving gear secured to one end of the
winding spring of the clockwork mechanism, an
intermediate driving gear train meshed with the
driving gear, a rack associated with the intermediate
driving gear train and disposed for vertical
movement within the frame and a driving axle
meshed through an intermediate follower gear with
the driving gear, the rack being normally kept at an
upper position by means of a spring and being
disengaged from the intermediate driving gear train
at the upper position but engaged with the
intermediate driving gear train on downward
movement and the intermediate follower gear being
supported on a shaft which extends through an
elongate aperture disposed on an arc of a circle
centring on a shaft of the driving gear, the elongate
hole allowing the intermediate follower gear to
deviate upwardly on rotation of the driving gear for
winding the clockwork, thereby disengaging the
intermediate follower gear from the driving axle.
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 and 2 are side sectional views of a toy
motor car in accordance with the present invention
at different stages in the operation thereof, and
Figure 3 is an eniarged view, partially cut away, of
the driving mechanism of the toy motor car of
Figures 1 and 2.
Referring now to the drawings, a chassis 1 is provided at its front upper end with a supporting plate 2 having a pin 3. The chassis 1 supports a frame 5 having an outer shell 4 in the form of a car body by means of the pin 3 of the chassis 1 which extends rotatably into a hole 6. Thus, the frame 5 is pivotally connected to the chassis 1 through the pin 3.
In addition the chassis 1 is provided at its rear end with driving means 9 for imparting energy to an internal clockwork mechanism 8 through a rack 7 by urging the frame 5 towards the chassis 1. The driving means 9 comprises a frame 10, a driving gear 11 supported within the frame 10 and secured to one end of the winding spring of the clockwork mechanism 8, an intermediate driving gear train 12 meshed with the driving gear 11, a rack 7 associated with the intermediate driving gear train 12 and disposed for vertical movement within the frame 10, and a driving axle 14 meshed through an intermediate follower gear 13 with the driving gear 11.
As shown in Figure 3, the clockwork mechanism 8 is disposed in a housing 15 formed on an inner face of the frame 10 opposite the driving gear 11. An inner end 8A of the winding spring is fixed in a groove 16 of the driving gear 11, and the outer end 8B of the winding spring is engaged in one of a plurality of recesses 17 formed in the circumference of the housing 15. Thus, the outer end 8B of the winding spring and the recesses 17 of the housing 15 prevent over-winding of the clockwork mechanism 8, because, if over-winding occurs, the outer end 8B of the winding spring slips out of one recess 17 and then slides on the inner circumference of the housing 15 to engage the next adjacent recess 17.
The rack 7 is provided with a guide pin 19, which is guided in a guide groove 18 formed in the frame 10. Thus, the rack 7 is vertically movable within the frame 10 through engagement of the guide groove 18 with the guide pin 19. The rack 7 is normally kept at the uppermost position thereof by means of a coil spring 20 which is secured at one end to a pin 29 extending from the frame 10 and at the other end to the guide pin 19. Also, the rack 7 is disengaged from the intermediate driving gear train 12 when in the uppermost position thereof, but meshes with the intermediate driving gear train 12 upon downward movement, because an input gear of the intermediate driving gear train 12, namely a driving wheel 21A of an accelerating gear 21 is adjacent a portion 22 of the rack 7 which is free of teeth when the rack 7 assumes the uppermost position thereof.
The intermediate driving gear train 12 comprises an accelerating gear train consisting of two accelerating gears 21,23 meshed with each other, the driving wheel 21A of the input accelerating gear 21 being meshed with the rack 7. A driven wheel 21 B of the accelerating gear 21 is meshed with a driving wheel 23A of the output accelerating gear 23, while a driven wheel 23B of the output accelerating gear 23 is meshed with the driving gear 11. The input accelerating gear 21 is supported on a shaft which extends normally to the frame 10 through an elongate aperture 24.
The intermediate follower gear 13 is supported on a shaft which extends through an elongate aperture 25 disposed on an arc of a circle centring on a shaft 1 1A of the driving gear 11. The elongate aperture 25 allows the intermediate follower gear 13 to deviate upwardly on rotation of the driving gear 11 in the anticlockwise direction, so as to disengage the same
From a driving gear 26 of the driving axle 14 of the toy motor car.
A coil spring 27 is disposed between the chassis 1 and the frame 5 biassing the frame 5 upwardly.
In operation, the frame 5 is urged downwards to contact an upper portion of the rack 7, which in turn is then pushed down. The motion of the rack 7 effects rotation of the intermediate driving gear train 12 and then the driving gear 11,so that the clockwork mechanism 8 is wound up. After repeating lowering of the frame 5, the energy stored in the winding spring may be released by freeing the toy motor car. Rotation of the driving gear 11 is then transmitted to the driving axle 14 through the intermediate follower gear 13 meshed with the driving gear 11,thus rotating driving wheels 28 fixed to the driving axle 14 for moving the chassis 1.
In conclusion, the toy motor car comprises the chassis 1 and the frame 5 pivotally connected together at the ends thereof, the coil spring 27 disposed between the chassis 1 and the frame 5 for resiliently biassing the same apart and the driving means 9 for imparting energy to the internal clockwork mechanism 8through the rack 7 by pushing the frame 5 down towards the chassis 1.
Thus the clockwork mechanism 8 may be wound up by carrying out a very simple operation, unlike previously proposed toy motor cars in which energy is imparted to a driving mechanism by turning the wheels, for example by repeatedly moving the toy motor car in contact with a surface. Thus, a toy vehicle in accordance with the present invention can conveniently be operated by a younger child.
Also, the driving means 9 comprises the driving gear 11 secured to one end of the winding spring of the clockwork mechanism 8, the intermediate driving gear train 12 meshed with the driving gear 11, the rack 7 associated with the intermediate driving gear train 12 for vertical movement within the frame 5, and the driving axle 14 meshed through the intermediate follower gear 13 with the driving gear 11, the rack 7 being normally kept at its uppermost position by means of the spring 20 and being disengaged from the intermediate driving gear train 12 at the uppermost position thereof but meshed therewith on downward movement and the intermediate follower gear 13 being supported on a shaft which extends through an elongate aperture 25 disposed on an arc of a circle centring on the shaft 1 1A of the driving gear 11, the elongate aperture 25 allowing the intermediate follower gear 13 to deviate upwardly on rotation of the driving gear 11 so as to wind up the clockwork mechanism 8, thereby disengaging the same from the driving gear 26. Thus, the driving means 9 is relatively simple and inexpensive to manufacture.
Furthermore, the shaft of the intermediate follower gear 13 is supported in the elongate aperture 25 disposed on an arc of a circle centring on the shaft 1 lA of the driving gear 11, the elongate aperture allowing the intermediate follower gear 13 to deviate upwardly upon rotation of the driving gear 11 for winding up the clockwork mechanism 8, thereby disengaging the same from the driving gear 26, so that the frame 5 can be pushed down to actuate the clockwork 8 without the toy car running.
The frame 5 can be repeatedly pushed down to wind up the clockwork mechanism 8 fully. The rack 7 is restored to its upper position by the elastic force of the coil spring 20 aftertheframe 5 has been pushed down. When the rack 7 has been restored to its upper position, it is disengaged from the driving wheel 21A of the input accelerating gear 21 of the intermediate driving gear train 12.However, the stored energy is not released from the clockwork as long as the axle 14 is prevented from rotating, because the intermediate follower gear 13 rotates anticlockwise and moves downwards within the elongate aperture 25 to mesh with the driving gear 26 of the driving axle 14, so that driving gear 11 is locked and cannot rotate even when the rack 7 is disengaged from the intermediate driving gear train 12, because, for example, the wheels 28 fixed to the driving axle 14 are being urged against the floor.
Any upward movement of the rack 7 when in mesh with the driving wheel 21A of the gear train 12 will cause the input accelerating gear 21 to ride up in a similar elongate aperture 24, where it can rotate freely. Thus, the toy car operates relatively efficiently.
Thus, in summary, the present invention enables the provision of an amusing toy car of simple construction in which a clockwork mechanism may be fully wound up so as to run the car by repeatedly pushing down the body of the car whilst holding the car stationary.
