DE102005061455B3 - Drive e.g. for bicycle with steering wheel that can be tilted in driving direction, has eccentric driving disk which sits directly on multi-speed gear hub of front wheel with disk and drive hub having common fulcrum - Google Patents

Abstract

The drive has an eccentric driving disk (1) which sits directly on a multi-speed gear hub (3) of a front wheel. The eccentric disk and drive hub having a common fulcrum. A ring having ball bearings (2) is provided radially outside the eccentric disk, to which a strength-exercising articulation arm (4) is fastened vertically from above and connected by a joint to a steering wheel.

Description

Previous Drive structures are designed on conventional bicycles and designed as an auxiliary drive. The driving force acts via a in the direction of travel swivel handlebars by means of linkage on a Gearbox on the drive hub. The seating position of a conventional bicycle leads This type of drive to dangerous balance problems.

A bicycle with a swivel handlebar is out of the DE 85 03 367 U1 known.

The Invention is a cost-effective, low maintenance, easy to handle and healthy Design a vehicle with arm drive. Also handicapped people should get the opportunity to move in this way sporty outdoors.

The invention has a drive eccentric disc ( 1 ) directly on a standard multi-speed transmission hub ( 3 ) of the front wheel is seated. This gives eccentric disc ( 1 ) and drive hub ( 3 ) a common fulcrum.

A ball-bearing ring ( 2 ) comprises the eccentric disc, on which is the force-exerting articulated arm ( 4 ), which runs vertically from above, attached. At the joint of the articulated arm ( 4 ) are two spring bars ( 10 ), these overcome the top and bottom dead center.

With the steering head ( 5 ) are two tubes ( 6 ) connected. These run horizontally parallel to the rear wheel. The pipes ( 6 ) receive an adapted radius bent to the rear wheel axle ( 7 ). In the end, the pipes ( 6 ) recessed and take the rear wheel axle. Due to the bending radius ( 7 ) results in a good stability for the rear wheel.

The pipes ( 6 ) receive for stabilization three connecting elements ( 8th ), the torsion of the tubes ( 6 ) prevent. These fasteners ( 8th ) are displaceable in the tube longitudinal direction and lockable in the appropriate position. At the connecting elements ( 8th ) are the front footrest ( 9 ), behind the seat and behind the rim brake attached.

The at the front connecting element ( 8th ) fixed footrest ( 9 ) is connected to the connecting element ( 8th ) of the seat and thus receives the necessary stability.

The Invention provides today's fun and fitness society a new possibility to move around in the fresh air. Even people who You may have problems with the lower limbs Ride the two-wheeler.

Function of invention

The driver of the rowing wheel sits in chair height on a seat with backrest, on the frame tubes ( 6 ) in front of the rear wheel. The feet rest on the footrest ( 9 ) directly behind the front wheel. The footrest ( 9 ) is braced to the rear, so that the driver can stomp it firmly. Both feet can be placed on the ground as quickly as possible for safety. Due to the dimensioning and course of the frame tubes ( 6 ) also gives a pleasant suspension.

It is driven by the handlebar which can be swiveled back and forth in the direction of travel, a short articulated arm pointing forwards and a vertically extending articulated arm ( 4 ), which on the ball-bearing ring ( 2 ) of the eccentric disc ( 1 ) is attached. At the joint, between the articulated arms, are two spring bars ( 10 ), which overcome the top dead center forward, the bottom dead center to the rear. This also results in the necessary direction of rotation of the eccentric disc ( 1 ) in the direction of travel.

In essence, the inner eccentric disc ( 1 ) with the vertical articulated arm ( 4 ) on the ring ( 2 ), pulled up when retracting the handlebars and pushed forward while pushing the handlebar forward. As a result, the eccentric disc ( 1 ) brought to a full turn. The drive joint arm ( 4 ) pivots in each case by half the eccentricity back and forth from the vertical center position.

With the multi-speed freewheel hub can be the rudder movement fast for a steering maneuver interrupt.

By the choice of translation lets in one Adjust adjusted rudder rhythm and appropriate power development.

The featured rowing wheel allows Upper body workout outdoors, promotes Coordination, fitness and the experience of driving through the environment is a not to be underestimated Enrichment.

Also handicapped persons have the possibility to drive the rowing wheel.

Claims (5)

Drive for a bicycle with a pivotable handlebar in the direction of travel, characterized in that a drive eccentric disc ( 1 ) directly on a commercial multi-speed transmission hub ( 3 ) of the front wheel sits eccentric disc and drive hub have a common pivot point, a ball bearing ring ( 2 ) the eccentric disc ( 1 ) radially outward, at this a force-exerting articulated arm ( 4 ), which extends vertically from above and is connected via a hinge to the handlebar, is attached. Drive according to claim 1, characterized in that a steering head ( 5 ) is provided that with the steering head ( 5 ) two pipes ( 6 ) are connected, which run horizontally parallel to the rear wheel. Drive according to claim 2, characterized in that the tubes ( 6 ) with adjusted radius ( 7 ) bent down to the rear wheel axle, are recessed for receiving the axle at the end and thereby the stable rear fork ( 7 ) form. Drive according to claim 3, characterized in that the tubes ( 6 ) for stabilizing three longitudinally adjustable fasteners ( 8th ), front a footrest ( 9 ), a seat at the back and at the end of the horizontal part of the pipes ( 6 ) a rim brake are attached thereto. Drive according to claim 4, characterized in that the front of the connecting element ( 8th ) fixed footrest ( 9 ) is tightened to the rear, and thus obtains the necessary stability.
