Definitions
- the object of the invention concerns a very light pedal bicycle, built mainly in light metal alloys and plastic parts with a structural format and specially simplified design so that with a minimum of movements or operations, a particularly extra-folded operation can be carried out of the complete bicycle. Extra folding operation that minimizes the whole of the bicycle.
- the development of the folded bicycle of the invention would be inscribed in the diameter of this regular bicycle wheel and its volume would be the equivalent of the same folded in two parts, so that it can be stored in a cover, bag or case and be comfortable and easily transportable in hand and not to mention in another higher volume vehicle, car, van, boat, motorcycle, light aircraft etc.
- the folding bike of the invention built on wheels with a much smaller diameter, equivalent to 30% of the diameter of a regular bicycle wheel, requires an appropriate transmission system so that with a comfortable ride pedal it develops a reasonable speed of travel. equivalent to 51.5% of the speed of a regular ride bike.
- An extra-folding bicycle according to the invention that without substantially altering its essential characteristics, can be equipped with a gear change; front or rear suspensions; or both means or front suspensions.
- a transmission system according to the bicycle of the invention in any of the aforementioned versions, which likewise, without essentially changing its main characteristics, can be carried out by traditional chain or pulley transmission with toothed transmission belt; by means of a plate with internal gearing also to chain or pulley with transmission belt and by means of transmission of concatenated gears in multiplier development, logically.
- folding bicycles have not been found and in no case bicycles folding by a system of rearticulation of its different members.
- the object of the invention has the special feature of being reduced to a minimum expression that, being a bicycle for use by adults of any size, although other smaller proportional models can be made for children, it is folded by means of simple operations, reducing it, as has said above, in a body of irregular quadriform configuration less than the size of a regular bicycle wheel, with a volume of +/- 65 x 45 x 25 cm.
- It is another advantage of the invention is that the folding and unfolding operations are very simple.
- the frame folds down the center of the bicycle in a compass shape without altering the distance between the centers of the drive axles of the original wheel drive transmission set. It is only necessary to unlock the hinge or hinge, remove the upper bar from one end and unplug the rear bar; loosen the respective flanges and lower the saddle and the telescopic handlebar stem;
- the front wheel is folded and the handlebar is removed by placing it on the folded body in respective pressure clamps. To unfold it, proceed in reverse. Once folded, it can be stored in some of the luggage described above.
- the armed / unfolded bicycle has the height necessary to be used by an adult of any size, so that a comfortable pedaling allows it, despite the smaller diameter of its wheels, to develop a very high speed. reasonable and proportional to that of regular size bicycles due to a multiplier effect compensated transmission system to drive more revolution of the rear driving wheel with the same or less effort than would be applied to a traditional bicycle.
- the bicycle object of the invention is built with the most modern traditional means and materials. In very light and highly resistant metal alloys and plastic materials. It is also built in the traditional way with most of its parts being affordable on the market. It is the design of the structure, the mode of the arrangement of its means, the folding solution achieved and the mechanical action chosen and a smaller diameter of its wheels - about 30% of the diameter of a traditional bicycle regular wheel, those that have concluded with a high-performance, extra-folding and absolutely portable bicycle.
- the structure of the bicycle object of the invention is formed by an irregular trapezoid definition frame cut by the seatpost, where the chassis composed of two parts coaxially connected are joined by a hinge or hinge that articulates on an axis that is the axle. of a set of intermediate gears of the transmission and that is the pivot axis on which it articulates, to open and close, the aforementioned hinge or hinge on which the assembly folds, closing in the form of a compass on the central shank of said saddle having previously released the upper bar and unplugged the rear bar by folding them against said central rod and, the lower part of the rear one, on the chassis.
- the frame of said frame is made up of two tubular rods.
- the previous prismatic section (according to this example) is attached to the steering stem, the rear cylindrical, consists of the corresponding fork for the rear wheel.
- the male part of the hinge and folding hinge and the female part are mounted in the rear shank.
- the hinge or articulation hinge that pivots on the axis of the multiplier intermediate pinion has a device for locking / unlocking the hinge or hinge open and closed positions.
- the rear shank and rear wheel and the entire drive mechanism rotates flattened against the central shank at an angle of less than 90 ° so that the distance between centers of the axles of rotation of the platter (or catalina) and of the intermediate sprocket, it is not altered, it is kept constant, which allows ensuring the simplicity of the folding that is completed by folding the fork and front wheel against the front frame of the chassis and disassembling the handlebar that logically comes out releasing the prisoner that fixes it to seatpost of the front wheel and logically having complied with the lowering of the upper and rear bar; having folded the pedals and being able to turn the saddle to align it with the rear wheel and the handlebar stem.
- the folding is carried out in the form of a compass closing it against the central stem of the saddle so that the handlebar, a crosshead with respective brake sleeves and handles, is placed on top of the folded block and can be held by its vertical stem by means of plastic clamps located in the central seatpost and in the rear seat of the chassis, conveniently aligned.
- the brake cables are not convenient, since when removing the handlebar they are loosened and have more than enough margin to bring the handlebar to its referred folding position.
- the first axis consists of well-known pedals and a plate with an internal crown and the second axis can have a ring gear for chain or toothed pulleys for a belt. toothed or gear for the ring gear ring.
- the folding hinge system is located in front of the first axle of pedals and chainring, but with this system the folding size of the bicycle is greater than in other cases.
- two or three sprockets can be added to the second or third axle in the case of using a chain to incorporate a classic bicycle gear change.
- a compensating device incorporated in the hinge compensates it to re-tension said chains to the extent, reasonably small, that they could be slackened, but maintaining the distance between centers of the respective axes of the chain. transmission unalterable or with variation "0" when folded, (see figures 28 and 29 in the drawings).

- Said lever (a triangular prismatic piece) (19) of the interlocking mechanism has a flange (19B) protruding below the hinge as an end to be able to press it (for example with the toe) to release it and thus proceed more easily folded to the bicycle, a fold that is fixed when the pin (23) locks in the notches (17C) and that is fixed again in the mounted position when the pin (23) locks in the extreme notches (17D). Positions that in its different phases can be seen in Figures 3 to 7B.

- a slot (17G) that has an arc sufficient to optionally and previously graduate or position said part (17) and consequently its bar (7) with the angle necessary to tension the chain (103) or (112) if, when folded, it caught a some clearance due to the position in which the aforementioned hinge (16) would have been mounted.
- This device can be used in any of the versions described, but the most logical thing would be to use it with the chain, since it is probable that with use, it has gaps due to wear on its various axes.
- the rear chain or second chain or belt (112) if this device is used, will have a slight variation between centers of the axes (11) and (14), but it is compensated by the traditional tensioning wheel (12) that will have its corresponding dock.
