Human-powered vehicles are being introduced to the popularity of pedal-driven bicycles, known as bicycles, and the popularity of sports equipment is evolving in the use of the machine as a result of 'vehicle traffic and thus air purity requirements'.

Costly manufacture and weight as well; that only the rear wheel can be used as a hub brake so it is used on strap machines. ✓.

The solution is to find a way through the many known handbrake solutions, each of which is called "frictional" braked by a separate hand lever on the rear wheel and individually on the front wheelchair. Its disadvantages in emergency situations are the rush of the hand leaving the handlebars and the mesh of the wires running to the hand lever. - ^Λ .

It is known to the rear wheel to brake the rear wheel by means of a pendulum actuated foot pedal as a pedal-operated freewheel. the 'safe operation' of the freewheel is therefore a 'prerequisite' for total reliable operation. Known solution is the handle and handle wheel solution or perfect;

The smooth operation of these in addition to the minute sound is a function of the degree of spring pressure and the wear on the edges.

-12 / 4Family known as a folding bicycle frame Csepel Müvek and the Swinn Bicycle Factory also use camping bikes. The disadvantage of the solution they use is that for the sake of folding the strong durable tubular frame has to be interrupted by the folding hinge which weakens the bicycle frame.

Type-testing led to my invention. I have found that it is expedient that the rollers placed in each of the teeth of the coupling as ball-bearings, due to the elastic element or elements - * double the coupling rolls with the leading planes of their orbits. ; forced movement and I used this on a bicycle so that the internal glide of the teeth always corresponds to the negative outer surface of the rollers.

Further, since the block brake applied to the belt brake prevents the blocking of the brake line from engaging in a blocking action, the addition of a spring delaying the transmission of the full brake action on the spring-loaded brake also prevents the accidental bell actuated at the same time.

When designing the bicycle frame, I realized that the purple design of the bicycle saddle was not just for comfort; not only serves to improve the suspension but also allows inflation of the bicycle hoses by providing a proper connection to the saddle carrier.

I also realized that if I make the saddle tube out of pivoting coaxial tubes, the bike frame will also be foldable at the saddle axle _x

In the center of the axle coupling according to the invention, a toothed fork with a bore in the center of the tooth can be fitted with a pedal which connects the drive dial includes rollers designed to engage the pins or elastic rings it is submerged in the opposite direction when turning in the opposite direction.

The present invention relates to a belt brake which comprises a belt spring partially surrounding the drum rim and the belt spring being coupled to a power transmission such that a brake block is secured to the transmission and the brake block is released by the brake spring.

A spring-loaded brake according to the invention is formed by a friction wheel drum arranged on a brake shaft having a cylindrical spring pulley preferably having a spring-loaded torsion spring at one end of the bracket to the other end of the spring housing fastened and an adjusting wire attached to the brake housing, preferably connected to the brake control thread.

Preferably, the free end of the bell hammer, which is centered symmetrically to the brake shaft, contacts the friction wheel in contact with the concave side of the bell.

The above brakes can be actuated when the toothed disc is mounted on one end of the brake control wire and the other end is mounted on the transmission connected to the belt brake, and the belt brake and spring-loaded brake control wire are engaged.

- ύ / 6 The above brakes can also be actuated advantageously if there are two opposite holes in the circumference of the toothed drive disc: brake control struts are attached, one of which is connected to the transmission of the belt brake and the other to the brake housing.

The bicycle frame of the present invention comprising a saddle support tube clutch assembly having a front and a rear fork is formed by securing the saddle tube and the first fork stiffened delta base to a hinged hinge, preferably a hinged hinge equipped with a valve.

Preferably, the double plate is secured to the saddle tube by inserting a ball seat, further comprising a guide bar on the double plate and a clamping bracket attached to the guide bar.

One end of the belt brake spring 10, the rotor of the brake block 12 and the bore at one end of the transmission 11 are co-axially rotated through an opening in the brake housing 47. The other end of the belt brake spring 10 is movably secured to the next bore of the transmission 11. The brake drum pad 48 is preferably secured to the brake drum face side 9 of the brake block 12 by adhesive. The brake control thread 5 is connected to the next bore of the transmission 11 in series. If the coupling / other half is to be operated synchronously with the belt brake 29, a further hole is formed in the transmission 11, into which the guide wire 30 can be coupled. The brake control thread 5 and the control thread 30 are housed within the guard 50. The protective cover 50 is fixed to the bicycle frame.

When actuated, the brake control filament 5 is tensioned on the transmission drum 9 by operating the principle of lever 11, acting on the lever, and clamping the brake drum 10 on the drum shell 9 and, if appropriate, tensioning the first brake with the control wire 30. When the brake control thread 5 is loosened, the belt brake spring 10 loosens around the brake drum body 9 and, if necessary, forces the belt brake lip 10 and the brake plug 12 from the drum body 9 with all-wheel drive. If both brakes of the bicycle are actuated directly by two independent brake control filaments 5 directly connected to the toothed drive disk 3, the control wire 30 is not connected to the transmission 11 to actuate the other brake, for example the spring-loaded brake.

The above was mounted on a folding bicycle frame Seu ^, which is shown in Figs. 13-16. are shown. Accordingly, the bicycle frame consists of a first fork 21, an attached stiffened groove delta base 22, a saddle tube 20, a piston 24 therein, a valve 25 mounted on the saddle tube 20 and a double plate 23 secured to the ends of the saddle tube 20. The piston 24 has a piston seal 46 and the bottom of the saddle support tube 20 is closed by a bottom sealing plate 45. The double plate 23 surrounds the saddle carrier tube 20 with the guide shaft 32, which is secured to the saddle carrier tube 20 by a clamping 33 of the guide shaft 32. The bore 26 has a pedal shaft 27 and a clutch 28 which actuates the belt brake 29 and the spring-loaded brake.

The operation of the folding bicycle frame and the pump is as follows. The bicycle frame can be folded around the saddle support tube 20 and the first fork 21 by loosening the clamp 33 or can be opened and opened by tightening the same clamp 33 when threaded. The saddle support tube 20 of the bicycle frame can also be used as a pump by moving the plunger 24 to which the saddle is mounted, when the bicycle hose is connected to the valve 25 by means of a suitable cable. When not in use, the valve 25 is closed, providing the saddle mounted on the piston 24 with height adjustment and suspension.

-ι? / ϊδThe freewheel solution of the coupling device according to the present invention, while providing secure coupling, is quieter and requires less material than conventional solutions. Two main pieces are sufficient to make the structure, and as a result, it can be produced at a lower cost.

Accident-free braking of the bicycle requires simultaneous braking of the rear wheel to a greater degree than the front wheel. Only braking the front wheel can cause accidents. In the event of an emergency, the consequence of improper ordering, failure, is prevented by the braking system included in my invention, according to which the front wheel is structurally delayed with respect to the rear. The bell integrated in the spring-loaded brake also serves to prevent accidents.

The weight of a bicycle is critical. The bicycle frame of the present invention provides sufficient mechanical strength at a lower weight. The assembly of known tubular frames with separate fittings does not increase their total weight. In a modern way, the bike frame made with direct bindings provides less deadweight. The solution of the present invention, combined with the use of a lightweight bicycle rider with state-of-the-art technology and material utilization, and the bicycle brake system described herein provides the ideal conditions for safer traffic.
