Abstract
Abstract The disclosure relates to a stabilizer attachment for a bicycle, and includes a clevis or furcated member positionable over a bicycle wheel and affixed to the wheel axle. A stabilizer mast projects upwardly from the clevis member and a ring-like loop member is adapted to be used in conjunction with the stabilizer mast. The loop member is preferably hand-held in a circumscribing position with relation to the mast so that the periphery of the loop member is spaced from the mast and a person holding the loop member and moving alongside the bicycle can use the periphery of the loop member to engage the stabilizer mast when it is desired to prevent the bicycle, while in motion, from tipping over and to thereby restore the cyclist''s balance. In an alternate embodiment the stabilizer mast is provided at one end with a rotatably mounted loop member. A suspended cable is passed through the loop member so that the periphery of the loop member will engage the cable when the bicycle tends to tip over and will thus stabilize the bicycle as it moves along a path parallel to the cable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A training device for teaching and improving bicycle riding skills, said device being attachable to a bicycle having a frame portion including front and rear fork members for respectively receiving a front and a rear wheel, and also including a seat for supporting a cyclist, said training device comprising a stabilizer mast, said mast having an unsecured upper end and means for detachably securing a lower end of said mast to the bicycle, said securing means including a member adapted for attachment to the rear wheel of said bicycle for supporting said mast in a substantially vertical position spaced rearwardly from and extending above said bicycle seat, and balancing means cooperating with said mast for applying a manual force to the bicycle when necessary to restore equilibrium to the bicycle and cyclist.
Claim 2
Dependent Claim
132 words
A training device for teaching and improving bicycle riding skills, said device being attachable to a bicycle having a frame portion including front and rear fork members for respectively receiving a front and a rear wheel, and also including a seat for supporting a cyclist, said training device comprising a stabilizer mast, said mast having an unsecured upper end and means for detachably securing a lower end of said mast to the bicycle, said securing means including a member adapted for attachment to the rear wheel of said bicycle for supporting said mast in a substantially vertical position spaced rearwardly from and extending above said bicycle seat, and balancing means cooperating with said mast for applying a manual force to the bicycle when necessary to restore equilibrium to the bicycle and cyclist.
Claim 3
Dependent Claim
34 words
A bicycle training device as claimed in claim 1, wherein said securing means includes a clevis member having bifurcated legs with each of said legs extending over an opposite face of said rear wheel.
Claim 4
Dependent Claim
42 words
A bicycle training device as claimed in claim 2, wherein the balancing means comprises a loop member adapted for accommodation over the unsecured upper end of the mast for selective engagement with the mast to manually apply a force thereto when necessary.
Claim 5
Dependent Claim
81 words
A training device as claimed in claim 3, further including a mounting bracket for supporting said mast, said bracket comprising a brace member attachable at one end to the bicycle frame below the seat and having a bifurcated portion including a plurality of spaced apertures extendible toward the clevis member, said clevis member being provided with oppositely directed arms for respective accommodation within said apertures to thereby secure the mast and to provide adjustability to the length of the brace member.
Claim 6
Dependent Claim
50 words
A training device as claimed in claim 3, further including a mounting bracket for supporting said mast, said bracket comprising a brace member attachable at one end to the bicycle frame below the seat, the other end of said brace member being provided with collar means for securing the mast.
Claim 7
Dependent Claim
56 words
A training device as claimed in claim 3, wherein the mast is comprised of an upper section and a lower section, said lower section being affixed to the clevis member and being adapted to telescopically receive said upper section therein, and clamping means for adjusting the extensible length of the upper section from the lower section.
Claim 8
Dependent Claim
99 words
A training device attachable to a conventional bicycle for teaching bicycling skills, said training device comprising a substantially vertical mast affixed to the bicycle and having an unsecured upper portion extending upwardly above said bicycle, means for securing a lower portion of the mast to the bicycle to prevent independent movement thereof with respect to the bicycle, and balancing means adapted to circumscribe the upper portion of the mast to permit the selective application of a manual force on the mast for restoring proper balance to the bicycle and cyclist thereon without restricting the forward movement of the bicycle.
Claim 9
Dependent Claim
99 words
A training device attachable to a conventional bicycle for teaching bicycling skills, said training device comprising a substantially vertical mast affixed to the bicycle and having an unsecured upper portion extending upwardly above said bicycle, means for securing a lower portion of the mast to the bicycle to prevent independent movement thereof with respect to the bicycle, and balancing means adapted to circumscribe the upper portion of the mast to permit the selective application of a manual force on the mast for restoring proper balance to the bicycle and cyclist thereon without restricting the forward movement of the bicycle.
