- (A) an integral, tubular metal frame having (i) a midsection in the form of a unitary goose-neck shaped body tube, said goose-neck shaped body tube having an upwardly extending rear portion, an inclined forward portion and a bow-shaped midportion intermediate said rear and forward portions;
- (ii) a rear section in the form of a metal tube bent in double to provide (a) a first "U"-shaped bend extending in a first plane, and bent again to provide (b) a second and a third "U"-shaped bend extending in two separate substantially parallel planes which are substantially perpendicular to said first plane and (c) a pair of generally parallel terminal portions, each of said terminal portions being shaped to conform to the periphery of the bow-shaped portion of said integral tubular, metal frame and fixedly attached thereto by brazing or welding, and said first "U"-shaped bend being positioned adjacent the upwardly extending rear portion of said body tube and being affixed thereto by brazing or welding, (iii) a forward section in the form of a metal head tube being fixedly attached to said body tube by brazing or welding, said forward section being engaged to (B) a steerable front wheel assembly rotatably engaged with said head tube, said steerable assembly comprising (i) a handle bar connected to a handle bar stem (ii) a front wheel having an axle rotatably coupled to said handle bar stem and fixedly attached to pedal arms to enable front wheel drive, said rear section of said metal frame being engaged to (C)(i) a seat post slidably engaged with said upwardly extending rear portion of said body tube (ii) clamping means to fixedly attach said seat post to said rear portion of said goose-neck shaped body tube;
- and (D) said rear section of said metal frame being engaged to a rear wheel assembly comprising (i) a pair of training wheel metal brackets, each of said brackets being fixedly engaged to opposite sides of the rear section of the metal frame (ii) a pair of traning wheels, each of said wheels being rotatably engaged to an opposite bracket (iii) a rear wheel having an axle rotatably engaged to said rear section.
A frame assembly for a miniature bicycle of a size suitable for children 11/2 to 3 years old comprising:
- (A) an integral, tubular metal member having (i) a midsection in the form of a unitary goose-neck shaped body tube, said goose-neck shaped body tube having an upwardly extending rear portion, an inclined forward portion and a bow-shaped midportion intermediate said rear and forward portions;
- (ii) a rear section in the form of a metal tube bent in double to provide (a) a first "U"-shaped bend extending in a first plane, and bent again to provide (b) a second and a third "U"-shaped bend extending in two separate substantially parallel planes which are substantially perpendicular to said first plane and (c) a pair of generally parallel terminal portions, each of said terminal portions being shaped to conform to the periphery of the bow-shaped portion of said integral tubular, metal member and fixedly attached thereto by brazing or welding and said first "U"-shaped bend being positioned adjacent the upwardly extending rear portion of said body tube and being affixed thereto by brazing or welding (iii) a forward section in the form of a metal head tube being fixedly attached to said body tube by brazing or welding.
A miniature bicycle of a size suitable for children 11/2 to 3 years old comprising:
- (A) an integral, tubular metal frame having (i) a midsection in the form of a unitary goose-neck shaped body tube, said goose-neck shaped body tube having an upwardly extending rear portion, an inclined forward portion and a bow-shaped midportion intermediate said rear and forward portions;
- (ii) a rear section in the form of a metal tube bent in double to provide (a) a first "U"-shaped bend extending in a first plane, and bent again to provide (b) a second and a third "U"-shaped bend extending in two separate substantially parallel planes which are substantially perpendicular to said first plane and (c) a pair of generally parallel terminal portions, each of said terminal portions being shaped to conform to the periphery of the bow-shaped portion of said integral tubular, metal frame and fixedly attached thereto by brazing or welding, and said first "U"-shaped bend being positioned adjacent the upwardly extending rear portion of said body tube and being affixed thereto by brazing or welding (iii) a forward section in the form of a metal head tube being fixedly attached to said body tube by brazing or welding, said forward section being engaged to (B) a steerable front wheel assembly rotatably engaged with said head tube, said steerable assembly comprising (i) a handle bar connected to a handle bar stem (ii) a front wheel having an axle rotatably coupled to said handle bar stem and fixedly attached to pedal arms to enable front wheel drive, said rear section of said metal frame being engaged to (C)(i) a seat post slidably engaged with said upwardly extending rear portion of said body tube (ii) clamping means to fixedly attach said seat post to said rear portion of said goose-neck shaped body tube;
- (D) said rear section of said metal frame being engaged to a rear wheel assembly comprising (i) a pair of training wheel metal brackets, each of said brackets being fixedly engaged to opposite sides of the rear section of the metal frame (ii) a pair of training wheels, each of said wheels being rotatably engaged to an opposite bracket (iii) a rear wheel having an axle rotatably engaged to said rear section, and (E) a "U"-shaped metal tube fixedly attached to the rear section of the metal frame above the first "U"-shaped bend extending opposite thereto and at an upward angle therewith to provide means for carrying packages or for pushing the bicycle.
