Description

Title : BICYCLING TRAINING DEVICE

BACKGROUND OF THE INVENTION The present invention relates to a device for training novice bicyclists on how to maintain balance on the bicycle. The present invention provides a safe and easy transition from training wheels to unaided mastery of bicycling skills. Numerous bicycle training devices are taught in the prior art. These include U.S. Pat. Nos. 5,791,675; 5,338,204; 4,917,398; 4,903,975; 5,028,066; 5,395,130; 5,407,222; 5,176,395; 5,344,171; 5,303,944; 5,217,240, and others. The present invention offers a stable learning platform giving direct feedback to the parent/trainer on the readiness of the child/operator to ride unassisted. The parent/trainer has complete control over the bicycle and can run at speeds necessary to get passed the instability of slow speed. An additional design benefit of the present invention is that the child is unable to see the parent/trainer and actually has no idea if he/she is riding solo. This builds confidence quickly, thinking that he/she is riding all by him/herself expediting the learning curve. The most important benefit is no more painful crashes and happy kids. SUMMARY OF THE INVENTION The present invention provides a bicycle training device mountable to a conventional bicycle frame and operable by a non-rider (parent/trainer) to guide and control the actions of the bicycle. A mounting bar may be affixed to the seat neck. A leg of the mounting bar extends rearwardly behind the bicycle seat above the rear wheel. Arms of the mounting bar extend outwardly. A clamping member is releasably attached at a first end by a clasp member to the outwardly extending arms. A release lever is attached to a second end of the clamping member at some distance behind the bicycle. Operation of the release lever causes the clasp member to engage or disengage from the arms, thereby releasing the non-riders control over the bicycle. In one embodiment of the invention the clamping member is attached at a first end to the bicycle frame at the seat neck and is released by pulling a release lever at the second of the clamping member.

Fig. 13 illustrates an embodiment of the present invention with a universal joint having a connection tab releasably engageable with a hollow tube of the clamping member. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Fig. 1 shows a perspective view of the training device 10 attached to a conventional seat neck bar 12 of a bicycle 14. The device 10 has a T-shaped mounting bar 16 attached generally perpendicularly to the neck bar 12 and extending rearwardly beneath the seat 18 and above the rear wheel 20. The mounting bar 16 has a pivot joint 22 which allows for rotation in the horizontal plane (± 40°). Attached to the mounting bar is the clamping member 24. In the position shown in Fig. 1 , a rider could be controlled and balanced by a non-rider guiding the bicycle 14 through the training device 10. As shown in Fig. 2, clamping member 24 has a generally cylindrical main shaft portion 26. At a first end 28, the clamping member has a forked section 30. The forks are two, spaced-apart, generally parallel, tubes which provide stability and strength to the device. One end of the fork has the junction of the two tubes and is attached to the main shaft 26. The other end of the fork has opposed, spaced-apart, C-shaped yokes 32 which fit around the arms of the mounting bar 16 as will be described below. Also, at the second end 28 is a clasp member 34 which engages around the mounting bar arms upon operation of a spring-loaded release clamp 36. At a second end of the main shaft 26 is a handle bar 38 with spaced-apart grip portions 40a and 40b. A grip closure lever 42 similar to the well-known bicycle hand brake is attached to the handle bar 38 at one of the grips. The lever 42 controls the opening and closing of the clasp member 34 via a cable 44 extending from the lever 42 to the spring-loaded release clamp 36. The main shaft 26 may be extended or shortened through well-known mechanisms such as telescoping action controlled by tightening collars 46. Thus, the non-rider may control the distance the handle bar 38 is away from the clasping member and the distance from the rider. The T-shaped mounting bar 16 is shown in Figs. 3 and 4. An attachment collar 50 may be tightened around the seat neck bar 12. The main leg portion 51 is divided by pivot joint 22 into front leg section 52 and rear leg section 53. The pivot joint allows for rotation of the rear leg section from + 40° in a horizontal plane (see Fig.4). Alternative pivot joints will be discussed below. At the end of the rear leg section 53, opposite the collar 50, is the horizontal arm 55 which has a left and right arm section (57 and 59, respectively). Each arm 57 and 59 has a recessed clasp notch 56 and 58, respectively, along a length of each arm section. These notches receive, engage, and center C-shaped yokes 32 on the clamping member 24. Fig. 5 illustrates a side elevation view of the T-shaped mounting bar 16. Pivot or swivel joint 22 is clearly shown. The leg is divided into a front leg section 52 and a rear leg section 53. The horizontal arm portion 55 extends left and right of the seat. A detailed top plan view of the second end 28 of the clamping member 24 is shown in Fig. 6. At the end of the fork section 30 are the opposed and spaced-apart C- shaped yokes 32. The clasp 34 is shown with spring-loaded release clamp 36 and activation cable 44. Fig. 7 shows the clasp 34 in the open position as pulled open by cable 44. An adjustment screw system 70 and pivot 72, well-known in the bicycle hand brake art, allows for closure adjustments to the clasp 34. C-shaped yokes 32 shown in Fig. 7 engage around the recessed notches 56 and 58 in the arms 57 and 59. Downwardly depending hooks 74a and 74b on clasp 34 wrap around the arms 57 and 59, respectively, when engaged by the release mechanism at the handle bars on the opposite end of the clamping member. Fig. 8 illustrates the clamping member 24 attached to the mounting bar 16, but the clasp 34 is in the open or release position. In this position the bicycle could be released by the non-rider by allowing the bicycle to slide out of the yokes 32. Fig. 9 shows the clasp 34 closed, but not engaged with the mounting bar 16. This figure simply illustrates how the hooks 74a and 74b may wrap around and form a closure about the arms. In Fig. 10, it may be seen how the closed clasp 34 holds the clamping member 24 to the mounting bar 16 so that the non-rider has control of the bicycle. The yokes 32 are retained in the notches 56 and 58 and centered on the horizontal arm 55 by the shoulders 76 on arms 57 and 59. In operation the mounting bar or T-bar 16, attaches to the seat neck 12. The T-bar 16 becomes the center of gravity once the child sits on the bicycle. The T-bar 16 incorporates a pivot joint 22 that rotates approximately + 40° in the horizontal plane. This feature dampens out the pendulum effect once the device 10 is attached and allows for "true free riding feel" by the rider without being out of control. The ends or shoulders 76 of the T-bar 16 are rounded to provide added safety. On the T-bar horizontal arm 55 indentation guides (or recess notches) 56 and 58 are provided to eliminate side-to-side slippage of the clamping member 24. An essential feature of the system is the clamping member 24. The design function is a controlling feedback device that secures the parent/trainer (non-rider) to the child (rider) learning to ride the bicycle. The clamping member 24 is approximately 4.5 feet long but may be varied by a telescoping action previously discussed. The clamping member 24 breaks down in two pieces for easy storage. This variable length ensures that the clamping member 24 safely clears the rear wheel 20 of the bicycle. With this clearance the parent/trainer can run behind the bicycle at full stride as necessary, thereby avoiding the unstable slow speed which results in crashes. Another important feature of the clamping member 24 is the bicycle style fork section 30. The fork section 30 attaches to the T-bar 16 at the C-shaped yokes 32 giving the parent/trainer the ability to prevent the child from falling sideways. The fork 30 also provides the strength to initially propel the rider to speeds that are comfortable. The fork 30 attaches to the T-bar 16 in the indentation portion (or recessed notches) 56 and 58 of the bar. The connection of the T-bar 16 and the clamping member 24 gives full rotation in the vertical making it comfortable to use for a short or tall person. Another unique feature that makes the present invention 10 successful is the release mechanism 34. This mechanism gives the invention a quick connect and disconnect capability. The release mechanism is spring-loaded closed or opened with the conventional arrangement of a traditional brake handle 42. Another important grappling feature is the full stopping control of the bicycle when attached in the closed position. This is the result of the hooks 74a and 74b in the release mechanism firmly securing over the horizontal arm 55 of the T-bar 16. The handle bar style clamping member 24 with fork 30 design gives the parent trainer the fulcrum capability to overcome the momentum of falling sideways. This ability along with the stopping capability due to the release mechanism are significant reasons for the present invention being a complete success at teaching kids to transition away from training wheels. Fig. 11 illustrates an embodiment of the present invention wherein the clamping member 24a utilizes a vertically oriented fork section 30a and a vertically oriented release mechanism 34a. Pivot 22a is provided to couple the fork section 30a to the main shaft section 26a. In the Fig. 11 embodiment, the clamping member 24a releasably attaches to the bicycle frame 70 at the seat neck 12. The clamping member 24a operates as has previously been discussed by action of a grip closure lever (42 in Fig. 2) which opens and closes the release mechanism 34a. Fig. 11 A shows how C-shaped yokes 32a engage the seat neck 12. Hook 74a on release mechanism 34a may be locked around the neck 12 to hold the clamping member 24a on the bicycle frame. Fig. 11 A shows the hooks 74a in the released position by action of activation cable 44a connected to the grip closure lever (not shown). An alternative embodiment of the mounting member and clamping member are shown in Fig. 12. At the first end 90 of the alternative clamping member 84 is a release mechanism 34b having an engagement lip 86. The release mechanism 34b may be moved from an attached (engaged) position to a second disengaged position by operation of the grip closure lever on the second end of the clamping member. The release mechanism 34b operates, as previously discussed, when the grip closure lever pulls on the activation cable 44b. When the lever is released the release mechanism 34b returns to the first engaged position. In Fig. 12, the mounting bar 16b has a pivot 22b as seen in Figs. 3 and 4, but rather than using a T-shaped mounting bar, the rear leg section 53b is provided with a pivotable engagement block 80 having a transverse notch 84. Block 80 is attached to rear leg section 53b by a pivot pin 82. In operation, the lip 86 is releasably received into notch 84 and the bicycle may be controlled by the non-rider. By activating the grip closure lever, the lip is able to disengage from the notch and the bicycle is released. The embodiment of Fig. 12 may pivot in both the vertical and horizontal planes. Fig. 13 illustrates yet another embodiment of the present invention. The mounting bar 16c is provided with a universal joint 23 which allows pivoting in both the vertical and horizontal planes. Mounting bar 16c may be attached to the bicycle neck as previously discussed with the other embodiments. A connector tab 91 having a locking hole 93 is attached to the rear yoke of the universal joint 23. The clamping member 85 has a locking pin release member 87 on the first end of the clamping member 87. Pin release member 87 passes through a hole 95 in the clamping member tube 89. In operation, the tab 91 is inserted into the open end 99 of hollow tube 89. Pin 87 engages and locks into the tab hole 93 and the bicycle may be controlled by the non-rider. Activation of the grip closure lever disengages the pin 87 from the tab 91 and the bicycle is freed from the non-rider's control. Although the invention has been described with reference to a specific embodiment, this description is not meant to be construed in a limiting sense. On the contrary, various modifications of the disclosed embodiments will become apparent to those skilled in the art upon reference to the description of the invention. It is therefore contemplated that the appended claims will cover such modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.
