## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority from the United States provisional patent application entitled MODIFIABLE BICYCLE SYSTEM, which was filed on Jun. 29, 2015, and assigned the Ser. No. 62/185,802.


BACKGROUND OF THE INVENTION
Field
The present invention relates generally to bicycles, and more specifically, to a bicycle system modifiable for use as a balance bike, scooter or pedaled bike.
Related Art
There are a variety of types of bicycles, herein defined as human-powered vehicles having two wheels attached to a frame, one wheel behind the other. One type of bicycle, a “balance bike” also known as a “Laufrad bike”, is propelled by the rider's feet striking the ground while the rider sits on a seat. Another type, a “scooter”, is propelled by one or the other, or by alternating both of, the rider's feet, typically while the rider is standing. A “pedaled” bike is propelled by the rider's feet exerting force on a mechanism that forces a wheel to turn.
It is difficult for some people to learn to ride a pedaled bicycle. For these people it may be useful to start with a simple bike using gross motor skills and balance, and incrementally transition to a pedaled bicycle which requires finer motor skills and more acute balance. Alternatively, some people simply want to ride different types of bikes depending on factors such as terrain, desired workout, and mood. Thus, it is desirable to have a single bicycle system that is modifiable for use as a Laufrad bike, scooter and pedaled bike. It is desirable that this modifiable bicycle is easy to modify, and easy to use.
SUMMARY OF THE INVENTION
A modifiable bicycle includes a frame that supports two wheels aligned one behind the other, a handlebar that can be raised and lowered, and a seat that can be removed. The bottom side of the frame includes a frame mount to which various components with mounting plates can be attached. The bottom side of the frame can include a couple of downward protrusions that can be used individually or together as a connection point for components. The bicycle can be modified in a variety of ways by adding and removing components so as to function as a pedaled bike, a balance bike, or a scooter.

Broadly, the bicycle system of the present invention includes a bicycle that has an elongated frame mount attached to, and protruding from, the frame. This elongated mount is the attachment point for a pedal assembly or for a foot rest assembly, depending on whether the bike is to be configured as a pedaled bike or a scooter. Alternatively, if nothing is attached to the elongated mount, the bicycle can be used as a balance bike.
Bicycle system of the present invention, generally referred to herein as 10, can be configured to be pedaled bike 10a (FIG. 1), balance bike 10b (FIG. 2), or scooter 10c (FIG. 15). The various bike configurations are achieved by employing specific components, for example pedal assembly 70, foot rest assembly 80, or foot board deck assembly 90, respectively.
Referring to FIG. 3, frame 60 includes elongated frame mount 25 which protrudes downwardly from frame and is longitudinally parallel to the frame. Frame mount 25 includes a means for attaching a plate, here shown as apertures 50.
Frame mount plate 25 serves as a connection site for a variety of component assemblies. By way of example, pedaled bike 10a has a pedal assembly 70 which includes a sprocket, chain and pedals, plus pedal mount plate 30 which releasably engages with frame mount 25. Similarly, balance bike 10b includes foot rest assembly 80 having peg rests 82 and peg mount plate 35. For simplicity FIGS. 3-5 show peg mount plate 35, but it should be understood that pedal mount plate 30 could likewise be used.
Referring to FIG. 8, peg mount plate 35 preferably includes two substantially parallel blades 37 with a space there between. As shown in FIG. 4, frame mount 25 fits between blades 37 of peg mount plate 35, with apertures 50 aligned. FIG. 5 depicts securing pedal mount plate 30 to frame mount 25 through aligned apertures 50 using bolt 40. As stated earlier, pedal mount plate 30 and peg mount plate 35 are similarly attached, and interchangeable.
Upon attachment of pedal mount plate 30 the chain must be connected to the sprocket of the rear wheel, in order to achieve pedal driven propulsion of the bike.
Referring to FIG. 7, foot rest assembly 80 is rotatable such that peg rest 82 can be oriented horizontally as shown, vertically, as shown in phantom, or in any position there between. In this manner a rider may use balance bike 10b in a manner where they can rest one or both feet on peg rest 82, or the rider can rotate peg rest 82 vertically so they have full range of motion during propulsion without the risk of inadvertently coming in contact with peg rest 82.
As shown in FIG. 8, each blade 37 preferably includes tapered edge 38, which helps guide peg mount plate 35 (or pedal mount plate 30) into position surrounding frame mount 25.
It is preferable for bicycle system 10 to employ a relatively tall handlebar system so the rider is comfortable regardless of the configuration as a pedaled, bike, balance bike, or scooter. As shown in FIG. 9, elongated handlebar is preferably achieved using male neck extension 100 that engages with frame 60, and female neck extension 105 that engages with male neck extension 100. Undesirable free rotation of female neck extension 105 relative to male neck extension 100 is achieved by engagement of projection 106 within groove 107. As shown in FIG. 10. Clamp 110 secures female neck extension 105 over male neck extension plug 100 (not shown). In this manner handlebars, female neck extension 105, male neck extension 100 and front wheel 109 all rotate as one unit. The handlebar stem is preferably approximately 28 to 32 inches high from the ground to the center of the handle bar.
Referring to FIG. 11, in an alternative embodiment, frame 60 has protruding lower front frame tube 65 and lower rear frame tube 66. Lower rear frame tube 66 is preferably permanently attached to frame, for example by welding, however these structures are not necessarily present in lieu of frame mount 25. As shown in FIG. 11, foot rest assembly 80 is engaged with lower front frame tube 65. Lower front frame tube is engaged with frame 60 at alternative peg mount plate 64. In this manner the bicycle system can be used as a balance bike.
As shown in FIG. 12, the bicycle system can be used as a scooter by engaging post mount 92 of foot board deck assembly 90 with lower rear frame tube 66, and resting front end of foot board deck assembly 90 on top of peg rests 82. Foot board deck assembly 90 is secured to peg rest 82 using straps 95 that are secured by buckles 96, as best shown in FIGS. 13 and 14. Referring to FIG. 14, post mount support 93 provides an abutment to post mount 92 (FIG. 13). As shown in FIG. 15, scooter 10c is normally operated without a seat.
Frame mount 25 and lower rear frame tube 66 are preferably constructed of steel, but other materials such as alloy or carbon fiber could also be used. The majority of the structures of the bicycle system are preferably constructed of steel, but other materials such as alloys could also be used. Such structures include: pedal mount plate 30; peg mount plate 35; blade 37; lower front frame tube 65; lower rear frame tube 66; peg rest 82; post mount 92; post mount support 93; buckle 96; male neck 100; female neck extension 105; projection 106; and clamp 110. Foot board deck assembly 90 is preferably constructed of plastic, but other materials such as wood or allow could also be used. Strap 95 is preferably constructed of nylon, but other materials such as leather could also be used.
In use, a user of bicycle system 10 selects a desired bicycle configuration from pedaled bike 10a, balance bike 1013, or scooter 10c. They then attach the corresponding component, pedal assembly 70, foot rest assembly 80, or foot board deck assembly 90, respectively. In the case of pedal assembly 70 and foot rest assembly 80, attachment is achieved by connecting pedal mount plate 30 or peg mount plate 35 to frame mount 25. In the case of pedaled bike 10a, the chain of pedal assembly 70 is attached to the back wheel. In the case of scooter 10c, foot board deck assembly 90 is engaged with lower front frame tube 65 and lower rear frame tube 66, with front end of foot board deck assembly 90 preferably resting on peg rests 82. In the case of scooter 10c the bicycle seat is removed. The user then may operate the bicycle in the desired configuration.
Specifications of certain structures and components of the present invention have been established in the process of developing and perfecting prototypes and working models. These specifications are set forth for purposes of describing an embodiment, and setting forth the best mode, but should not be construed as teaching the only possible embodiment. Rather, it should be understood that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
