Toy finger operated bicycle

A toy bicycle that is a scale model including frame, seat, handlebar, front and rear wheel and drive assemblies comparable to a full-sized bicycle. There is also included front and rear braking mechanisms that can be readily and easily finger operated. The bicycle includes pedal and foot pegs that are oversized relative to the other components to facilitate finger operation of the bicycle. The handlebar is provided with projections to enable one playing with it to perform stunts.

BACKGROUND OF THE INVENTION 
Bicycles have long been a popular means of transportation for children and 
adults. Younger children although not old enough to ride are also very 
fascinated by bikes and while small toy-like plastic versions have been 
around they do not truly resemble a typical bicycle since they do not have 
the various moving parts such as moving wheels, pedals, brakes, sprockets, 
belts etc. so that the toy bicycle truly simulates a bicycle they see 
their brothers, sisters and friends riding down the street. Thus, there 
has long been a need for an essentially true-scale model of a bicycle so 
that one not old enough to ride can pretend and play with a bicycle very 
much like his older brother and sister. The toy bike must be capable of 
being operated by ones finger to pedal the bicycle, apply brakes to the 
front or rear wheels, do "wheelies" which consists of pulling the front 
wheel of the ground and riding on the rear wheel and other tricks and 
movements one can do on a full-sized bicycle. 
SUMMARY OF THE INVENTION 
In accordance with the present invention there is illustrated and disclosed 
a bicycle that in a preferred embodiment is essentially a toy size such as 
a 1/15.sup.th version of a full-sized bicycle that is capable of being 
operated like a regular bicycle by ones fingers. It contains the basic 
parts of a bicycle such as front and rear tire wheels; pedals, sprockets 
and a belt drive assembly for the rear wheel, seat, handle bars and frame 
and novel front and rear brake assemblies so that one playing with the toy 
bike can do everything one riding a regular bicycle is doing. 
The foregoing and other objects, features and advantages of the present 
invention will become apparent from the following description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
The present invention as illustrated in perspective in FIG. 1 is 
approximately a 1/15.sup.th scale replica of bicycles having features for 
accommodating the fingers of the user in order to control the bike and 
perform tricks and/or stunts. While a preferred embodiment has been 
illustrated other accessories may be provided and may be included in play 
sets along with the basic features of a bicycle. 
The component parts of the bicycle 10 can best be understood by reference 
to the exploded view thereof shown in FIG. 3 in conjunction with FIGS. 1 
and 2. Other features such as the front and rear brake assemblies will be 
dealt with when discussing FIGS. 4-10. 
It is intended that the bicycle is finger operated and in describing the 
various components of the bike the features that facilitate the finger 
operation will be described in greater detail. 
As illustrated in FIG. 3 the bike consists of a main frame member 20 that 
includes a tubular portion 22 that is designed to slidably and 
frictionally receive one end of a seat post 24. The other end of the seat 
post 24 securely receives a seat 26. That seat 26 is fitted with a seat 
cover 28 that is made of rubber or some other high frictional material so 
that one placing a finger F thereon such as shown in FIG. 1 the finger 
will readily grip and move the bike. 
Secured to the tubular post 30 is a fork member 32 that at its upper end 
has a tubular extension 34 that fits into the tubular post 30 as shown in 
FIG. 4. Within the tubular extension 34 is located a front braking member 
which will be described in greater detail with respect to FIGS. 4 and 5. 
Also, secured to the tubular extension 34 as shown in FIG. 4 is the handle 
bar assembly 36. The handle bar assembly 36 included handgrips 38 and also 
has inwardly extending projections 40. As shown in FIG. 1 these 
projections may be engaged by a finger F to raise the front wheel and thus 
perform a "wheelie" that is a stunt that one sees an expert bike rider do 
to impress his friends. In place of the projection a single curved bar 
could be used if desired 
Connected to the fork member 32 at its lower end by an axle 42 is a wheel 
44 on which is located a tire 46 having a soft gripping surface. Threadly 
secured to the ends of the axle 42 are oversized foot pegs 48 so that one 
can finger grip the axle and move the bike as shown in FIG. 1 
Secured to the horizontally disposed tubular support 50 at the midsection 
of frame 20 is a pedal-crank-axle-sprocket assembly 52 that when operated 
will drive the rear wheel 54 in a manner to be later described. 
The pedal-crank-axle-sprocket assembly includes oversized pedals 56, which 
facilitate finger actuation as shown in FIG. 2. A pedal 56 is connected to 
right crank 58 and also to left crank 60. Connected to the cranks 58, 60 
and drivingly connected to a front sprocket 62 and cranks and extending 
through the tubular support 50 is an axle 64. The sprocket 62 drives the 
rear wheel 54 through the connected belt 66 and sprocket 68. The sprocket 
68 is connected to the wheel 54 covered by tire 70 by the rear axle 72. 
Connected to the ends of the axle 72 are rear pegs 74, which are oversized 
to facilitate finger gripping thereof to drive the bicycle. 
Having now described the various structural components of the toy bicycle 
reference is made to FIGS. 4-12, which disclose details of the novel 
braking systems for the front and rear wheels. 
Referring now to FIGS. 4 and 5 there is illustrated the novel braking 
system for applying a stopping action to the front wheel 44. The essence 
of the system is to push down on a brake pin 80 to engage the tire 46 to 
stop the wheel 44 and thus the bicycle. When one releases the brake pin 80 
it will become disengaged and the brake is no longer applied. In the 
illustrated embodiment a resilient plug 82 is connected to the pin and 
when pushed down as shown in FIG. 5 the tire is engaged and when released 
will return to the position shown in FIG. 4 where it is disengaged from 
the tire. Other equivalent systems could be used. In FIGS. 6-10 there is 
illustrated one of two novel rear braking assemblies. In the preferred 
embodiment wherein the frame is relatively rigid the rear brake is 
actuated by movement of the seat and seat post. Another type of rear 
braking system is also illustrated such as a member secured to the frame 
and positioned to engage the rear wheel when a flexible frame is flexed as 
shown in FIGS. 11 and 12. 
Essentially, the seat post 24 extends through the tubular portion 22 and 
fits tightly into a recess 90 formed in the braking member 92 (see FIG. 
6). The braking member 92 includes an upstanding tubular section 93 and a 
downwardly projecting member 94 connected to section 93 by plate 95. 
Member 94 has a braking pad 96 secured to its lower end. This when the 
seat 26 and seat post 24 are pushed downwardly as shown in FIG. 7 the 
member 92 will fulcrum about the frame 20 at 98 to move the braking pad 96 
into engagement with the tire 70 to stop wheel 54. It is noted that 
downwardly projecting member fits into slot 100 in frame 20 to prevent the 
seat post 24 and seat 26 from rotating. When the finger is removed from 
the seat the resilience of the braking member which in the illustrated 
embodiment is plastic will return the braking member to the disengaged 
position as shown in FIG. 6. 
In the rear braking embodiment illustrated in FIGS. 11 and 12 the frame 110 
is considered to be a flexible frame in which the seat 26 is on the seat 
post 24 that fits into tubular portion 22. 
Extending from the tubular portion 22 at the upper intermediate portion of 
the maid frame 110 is a downwardly depending member 112. The depending 
member 112 extends between tow upwardly extending spaced arms 114 of the 
maid frame 110 surrounding the tire 70 (FIG. 7). The frame 110 is 
sufficiently flexible whereby applying downward pressure on the seat 26 as 
shown in FIG. 11 the end of member 112 engages tire 70 to stop wheel 54. 
Removing one's finger from the seat 26 will result in frame 20 returning 
to its unflexed position and member 112 moving away from the tire to 
release the braking action. 
It is intended to cover by the appended claims all modifications and 
features which fall within the true spirit and scope of the invention.
