Abstract

A retractable bicycle pedal which allows passengers to ride along on the luggage rack. Specifically, the invention is characterized in that the pedal is mounted independently for the passenger and can be pulled out via the extended pedal axle.

Description

Description • · ·· ····

The invention relates to a bicycle pedal, in particular for the simultaneous use of two persons.

Bicycle pedals are known in various forms, but always designed only for the foot width of a person. If a second person is carried along on the luggage carrier as a passenger, this normally can not contribute to the propulsion of the bicycle. An existing product (Vigurvant) approaches this problem by allowing the pedal to unfold. Here, the passenger has due to the narrow design of the folding pedal little stop on the pedal. In addition, the fold-out pedal can only be loaded from one side and the forces to be transmitted are unfavorably introduced into the pedal.

My invention is intended to eliminate these problems by the displaceable pedal body 11 for the passenger, via an axis 1, extendable and at the same time is mounted independently rotatable.

The invention provides a retractable bicycle pedal which optionally provides space for two feet side by side. The bicycle pedal consists of a main pedal body 5 which is mounted by means of two bearing sleeves 4, and 6 radially on the pedal axle 1. A sealing ring 2 reduces vibrations in the axial direction and allows a play-free fit of the main pedal body 5 in the axial direction. The slip rings 3 and 7 reduce the friction of the bearing sleeves. The detachable fixing of the main pedal body 5 is achieved by a washer 8 and a retaining ring 9.

The extendable bicycle pedal is characterized in that a second pedal body 11 is movably mounted on the extended pedal axle 1 by means of two bearing sleeves 10 and 15 in the axial and radial directions.

In order to ensure the fixed position of the second pedal body 11 on the pedal axle 1 is provided (in the radial direction) positive connection between the pedal body 5 and the pedal body 11 and a frictional connection (in the axial direction). The latter consisting of two round grooves in the pedal axle 1 and a pin 12, which obtained by a compression spring 13 and a threaded pin 14, the necessary biasing force to hold the pedal body 11 in the respective groove and thus in position.

In order that the displaceable pedal body 11 can not slide off the axle, a washer 17 and a securing ring 18 are also attached to the outer end of the pedal axle 1.

A sliding ring 16 reduces the friction occurring between the bearing sleeve 15 and washer 17.

The slidable pedal body 11 is conically shaped. The tapering of the tread surfaces of the pedal body 11 towards the outside allows an ergonomically better foot position of the passenger on the pedal body 11.

Grub screws 19 are screwed into the Auftritttsflächen the pedal body 5,11 to guarantee the necessary hold of the shoes on the pedals.

The invention will now be further elucidated with reference to an embodiment shown schematically in the drawings.

Claims (8)

Extendable bicycle pedal, characterized in that the extended pedal axle (1) next to the main pedal body (5), which is mounted in the radial direction freewheeling, a displaceable pedal body (11) aufweisst due to the extended pedal axis (1) and the use of Bearing sleeves (10, 15) mounted in free running in the axial and radial directions, whereby it can be pulled out, if necessary, coaxially to the pedal axle (1) to allow a second person pedaling on the same bicycle pedal. 2. bicycle pedal according to claim 1, characterized in that to ensure the fixed positioning of the displaceable pedal body (11) on the pedal axle (1) in addition to a positive connection in the radial direction between the main pedal body (5) and displaceable pedal body (11) and a frictional connection is provided in the axial direction, which consists of two round grooves [radially to the pedal axle (1)] in the pedal axle (1) and a pin (12) which is designed at its contact surface to the pedal axle (1) spherical and by a compression spring ( 13) and a threaded pin (14) receives the necessary biasing force engage in the respective groove and thus to keep the sliding pedal body (11) in position. 3. Bicycle pedal according to claim 1, characterized in that on the screw thread of the pedal axle (1) opposite end, a sliding ring (16), a washer (17) and a locking ring (18) are mounted, so on the one hand due to the sliding ring ( 16) the friction between the displaceable pedal body (11) and the washer (17) is minimized and, secondly, due to the securing ring (18), the unwanted slipping of the displaceable pedal body (11) from the pedal axle (1) is avoided. 4. bicycle pedal according to claim 1, characterized in that both for the storage of the main pedal body (5) and for the storage of the displaceable pedal body (11) bearing sleeves (4,6,10,15) find use that allow a low installation height, With minimized total height of the bicycle pedal, to be able to dimension the heavily loaded pedal axle (1) larger. 5. bicycle pedal according to claim 1, characterized in that the displaceable pedal body (11) has a bilateral, conical taper of the Aufstandsfiäehen, which causes a rotation of the knee to the outside thereby for the person traveling along an ergonomically better position of the lower extremities and at the same time avoiding collisions with that at the main pedal body (5) kicking is achieved. 6. bicycle pedal according to claim 1, characterized in that in the footprint of the main pedal body (5) and in the displaceable pedal body (11) threaded pins (19) are screwed, which a non-slip grip of the shoes on the pedal bodies (5, 11) allow. 7. bicycle pedal according to claim 1, characterized in that due to the elastic properties of a sealing ring (2) and the unchangeable position of the securing ring (9) a constant, easy press fit of the main pedal body bearing is achieved by unwanted play in the axial direction, as well as the contamination Contact surfaces between the pedal axle (1) and the bearing sleeves (4, 6) to prevent. 8. Bicycle pedal according to claim 1, characterized in that slip rings (3,7) reduce the frictional forces between the flanges of the bearing sleeves (4, 6) and the sealing ring (2) or the washer (8). 4/13 Florian Novak
