Claims
I claim:
1. A multi-purpose toy vehicle comprising a platform having a width
comparable to its length and having a pair of rear wheels, flanges
attached to the sides of said platform for separately mounting said
rear wheels independently of each other, a front steering wheel
mounted on a caster on the front of said platform for providing a
swivel joint, said caster comprising a bracket attached to the
front center of said platform, said bracket having an upwardly
extending bearing portion from its front end portion, a swivel rod
extending through said bearing portion, a bifurcated steering wheel
mount connected to the bottom of said rod, and a semi-circular tube
connected to said rod in a manner so that its lower edge is
rotatably slidable on the top edge of said bearing portion, a
handle extending upwardly at an acute angle from the vertical axis
of said caster for steering said front wheel, so that when the
handle extends forwardly of the vehicle, it may be used to pull or
tow the vehicle, and when rotated 180.degree. about said vertical
axis, it may be used by the driver, while standing on the platform,
for steering the vehicle.
2. A vehicle as recited in claim 1, including wheel mounting plates
attached to the sides of said platform each carrying an axle for
providing separate mountings for said rear wheels at a position
slightly below the lower surface of said platform to provide a low
bed.
3. A vehicle as recited in claim 2, together with angles irons
attached to the sides of said platform, wheel mounting plates
attached to the outside of said angle irons, each including axles
for rotatably supporting said rear wheels.
4. A vehicle as recited in claim 3, together with a brake operating
rod having ends rotatably supported on said angle irons, a brake
pedal rigidly attached to the top portion of said brake operated
rod, and brake equalizing linkage means mounted underneath said
platform for braking said rear wheels.
5. A vehicle as recited in claim 4, wherein said brake equalizing
means comprises a pin rigidly secured to said braking rod and
extending through a slot in said platform and into a hole in the
center of an equalizing bar, brake operating bars extending
longitudinally along the sides and underneath said platform and
including brake shoes at the rear end thereof for braking the rear
wheels as a result of longitudinal rearward movement of said bars
as a consequence of rearward movement by said pin of said
equalizing bar.
Description
This invention relates to a scooter-like toy vehicle but which is
mounted on three wheels instead of two.
An outstanding disadvantage of conventional, foot operated, two
wheeled scooters is that small children have difficulty in
balancing themselves thereon, making the vehicle unsafe for small
children.
Another disadvantage is that scooters have no utilitarian use other
than to provide a ride for the driver.
An object of the present invention is to provide a novel, three
wheeled toy vehicle which is devoid of the above named
disadvantages of scooters and which provides greater safety for
small children in that little or no skill is required for balancing
the driver.
Another object of the present invention is to provide a dual
purpose, three wheeled, scooter-like toy vehicle which serves both
as a wide track scooter and which, by turning the steering wheel
handle 180.degree. will enable such handle to be used to tow the
vehicle to enable carrying of very heavy objects, such as a load of
groceries, stacks of newspapers to facilitate delivery thereof by
newsboys, etc.
Other objects and advantages will become more apparent from a study
of the following description taken with the accompanying drawing
wherein:
FIG. 1 is a top or plan view of a three wheeled toy vehicle
embodying the present invention;
FIG. 2 is a side view thereof;
FIG. 3 is a bottom view thereof;
FIG. 4 is a cross sectional view taken along line IV--IV of FIG.
1;
FIG. 5 is a similar view showing the brake in applied position;
and
FIG. 6 is a fragmentary side view of the braking element.
Referring more particularly to the drawing, numeral 1 generally
denotes a scooter-like vehicle embodying the invention and
comprising a platform or base 2 of very substantial width and area
mounted on three wheels, namely, two rear wheels 5 and a front
steering wheel 8.
The front steering wheel 8 is pivotally mounted on a caster
comprising a supporting bracket 9 rigidly secured to a vertical
shaft 10 which is journaled within an integral sleeve or bearing
portion 7 of a front bracket 6. A semi-circular sleeve portion 10a
is attached to the front of shaft 10 so that its bottom is slidably
rotatable on the top of bearing portion 7. A handle 11, 12 is
rigidly secured to an integral extension of the semi-circular
sleeve portion 10a by bolts or similar fastening elements. Thus as
the handle is steered to the right or left, it will rotate the
shaft 10 within the bearing portion 7 so as to correspondingly
steer the front steering wheel 8 to the right or left,
respectively.
It will be noted that when the handle 11, 12 is in the dotted-line
position shown in FIG. 2, it will be used for steering the vehicle,
such as the handle of an ordinary scooter. However, when the handle
is rotated 180.degree. so as to assume the position shown in full
lines in FIG. 2, it will be useful as a tow, so that the housewife
or newsboy may pull the handle and tow the vehicle when loaded with
groceries, newspapers, or other objects resting on platform 2.
Attached to the upper sides of platform 2 are angle irons 3 whose
bottom flanges are bolted to the side edge portions of platform 2
and onto the side flanges of which are bolted wheel mounting plates
or brackets 4, which carry the axles for mounting the rear wheels
5.
In order toaid the driver in steadying or balancing himself, rods
or handles 14 are mounted, at their lower ends, on clamps or
brackets 13 which are attached to the front ends of angle irons
3.
A braking system is provided comprising a metal rod or tube 16
whose end portions extend through snugly fitting holes in the front
portions of the angle irons 3 to provide journals therefor. A brake
pedal 17 is rigidly secured to the right side portion of said rod
or tube 16. The brake is applied by depressing the front portion of
the pedal, since the tube is turned within its bearings in the
angle irons 3 and by virtue of a link 18 which extends through the
center of the rod or tube 16 and is rigidly bolted thereto, which
link 18 passes through a hole 21 of an equalizing bar 20, which bar
is pivoted at its ends to the front ends of braking bars or links
22 which have downturned ends 24 serving as brake shoes which
frictionally engage the rear wheels 5. Slots 23 are provided in the
braking bars 22 so that such bars may be guided in their forward
and rearward sliding movement with respect to similarly shaped top
supporting plates (not shown) rigidly fastened to the underside of
the platform 2. A return spring (not shown) may encircle tube 16 to
normally release the brakes.
In operation, brake pedal 17 is pushed forwardly so as to rock the
tube 16 as well as the driving pin 18 from the position shown in
FIG. 4 to that shown in FIG. 5. This will push the equalizing bar
20 rearwardly together with the braking bars 22 so as to bring the
braking shoes, that is, the rear, downwardly turned flanges 24 (see
FIG. 6) of the braking bars, into frictional engagement with the
rear wheels 5 in the dotted line position 24'. Of course, brake
shoes (not shown) may be attached to the downwardly turned ends 24
of the braking bars, if so desired.
It should be particularly noted that the three-wheeled toy vehicle
described has an extremely low bed or platform 2 relative to the
height of the ground by virtue of the specific construction shown
for mounting the rear wheels, which is devoid of the usual axle
therebetween. This provides greater safety because of the
considerably reduced likelihood of overturning when negotiating a
turn.
Moreover, it will be noted that very simple and inexpensive
standard parts are used for assembling the entire vehicle,
therefore considerably reducing the manufacturing cost thereof
while at the same time improving the performance of the toy
vehicle.
It will be further noted that while handles 14 are shown on both
sides of the vehicle to allow steadying of the driver, one or both
may be omitted if so desired.
Thus it will be seen that I have provided an extremely versatile
toy vehicle which is useful either as a wide track, low bed
scooter-like toy for steering by the driver while pushing with one
foot while the other foot rests on the platform, or which by
turning the steering handle 180 .degree., from the dotted line
position 11' to the full line position in FIG. 2, may be used as a
dolly or towing vehicle for towing groceries, newspapers, or other
heavy loads which are otherwise very difficult to carry.
While I have described a single specific embodiment of my
invention, it will be understood that this is by way of
illustration only, and that various changes and modifications may
be made within the contemplation of my invention and within the
scope of the following claims.
