Abstract

Abstract A foldable, portable bicycle in which the handlebar, its elongated post, the seat assembly, the pedal crank and the frame are foldable quickly and easily into a compact and regular-shaped package that is easily portable and storable, and are unfoldable with similar speed and ease into a safe, durable and comfortable bicycle that accommodates adults of normal size. The frame is designed with a low profile that is substantially the same in height and thickness as the dimensions of the wheels and their supports, and the handlebar and seat assemblies extend upwardly to normal height, but fold and collapse in novel ways, along with the pedals, to substantially within the confines outlined by the folded frame. Unique quick-release latches are provided for the handlebar post, the seat post sections, the frame hinge and the pedal hinges, and the pedal cranks are specially designed for effective performance and easy, compact folding. Optional features include an enclosed front carrying compartment, a bracing cable permitting the seat post to be made of lighter materials, a rear carrying rack that extends the flat and low profile across the rear frame section, and a shopping cart mode in which the partially folded frame is held with the two bicycle wheels parallel, and an auxiliary wheel assembly stored in the mid-portion of the frame is swung out to form a 3-wheel cart with a carrying deck. Numerous additional detailed features are included in the disclosure.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 154 words
In a foldable and portable bicycle, the combination of: first and second members that normally are disposed in side-by-side relation in a normal operating position and are swingable apart about a hinge between said members defining a hinge axis along one side; and a latch for holding said members releasably in said normal operating position, comprising an actuator arm, a first pivot spaced from and parallel to said hinge axis between one end of said actuator arm and said first member, a second arm lying alongside said actuator arm, a second pivot parallel to said hinge axis overlying said first pivot and connecting one end of said second arm to said second member, and a pivotal connection between the free ends of said arms, said pivotal connection being movable in one direction relative to said pivots into an overcenter latched position, and in the opposite direction relative to said pivots to an unlatched position.
Claim 2
Dependent Claim 154 words
In a foldable and portable bicycle, the combination of: first and second members that normally are disposed in side-by-side relation in a normal operating position and are swingable apart about a hinge between said members defining a hinge axis along one side; and a latch for holding said members releasably in said normal operating position, comprising an actuator arm, a first pivot spaced from and parallel to said hinge axis between one end of said actuator arm and said first member, a second arm lying alongside said actuator arm, a second pivot parallel to said hinge axis overlying said first pivot and connecting one end of said second arm to said second member, and a pivotal connection between the free ends of said arms, said pivotal connection being movable in one direction relative to said pivots into an overcenter latched position, and in the opposite direction relative to said pivots to an unlatched position.
Claim 3
Dependent Claim 31 words
A foldable and portable bicycle as defined in claim 1 in which said actuator arm is channel shaped and said second arm lies within the actuator arm in the latched position.
Claim 4
Dependent Claim 29 words
A foldable and portable bicycle as defined in claim 2 in which said second arm has reversely threaded connections at its ends for selective adjustment of its effective length.
Claim 5
Dependent Claim 100 words
A foldable and portable bicycle as defined in claim 1 in which said first member is a hinge base with said hinge axis along one of its sides, and said second member is a base plate for a steering post and being swingable upwardly when unlatched, said arms extending upwardly from said members to be alongside the steering post in the latched condition, and being swingable away from the post to the unlatched position to permit upward swinging of said base plate, and being extended across said hinge base as the base plate is swung away from the hinge base.
Claim 6
Dependent Claim 95 words
A foldable and portable bicycle as defined in claim 1 in which said first member as an upright end of a first frame section and said second member is an upright end of a second frame section and is swingable away from said first frame section as the frame is folded, said arms extending longitudinally along one of said frame sections in said latched condition and being movable laterally to the unlatched position, and being extended across said ends as the end of the second section swings away from the end of the first section.
