Abstract

Pulley lifting drive, which is mechanically driven mainly by means of an up and down movement by raising and lowering a foot or both feet of the operator with the help of its own weight and the necessary physical strength, because the pulley lifting drive with its pulleys and cables between its 2 construction parts A and B is attached to them, since they move apart mechanically during operation from Pos. 1, to reach Pos. 2 and then come back to Pos. 1, characterized in that a driven pulley by rolling its pre-rolled rope, which around the Multiple is longer than the lift height of the drive, is driven and drives a driven wheel or more drive wheels, said rope length described, which is responsible for many turns, can only be used because it is also wound in part by the extension pulley, which is their turn from the arranged next to her frictionally composite The translation pulley also gets its power from the automatic unwinding of its previously unrolled rope end ...

Description

State of the art

By former searches by the German Patent Office and the latest own searches of the usual I have experienced sources that drives through the use of dead weight and Muscle strength a lifting height take advantage and a sports equipment forward moving, using racks, gears, gears, chains etc. in their mechanics such as inline skaters or scooters.

There is a US patent P US 5,492,345 A ; There are running shoes described on two different sized wheels. The drive is made by simply rolling a rope end that is determined by the lifting height by lifting a foot.

These Construction is very problematic because of a very short rope end preferably many powerful turns for the drive wheel must be generated. To create an improvement and speed-up of the mileage, need to drive wheels with a much faster speed than the other wheels or Rollers in the running action intervene. The oversized drive wheel already points out that in this version no more satisfactory, more powerful and longer Propulsion can be done. Furthermore allows the long design and low ground clearance of the chassis no safe driving over Bumps. The holder of the mechanism does not allow more To arrange roles to the benefits of to be able to use several roles.

In another patent WO 03/084621 A1 a running shoe is described on 4 wheels. Although this construction is driven by means of a rope belt and pulleys, it bears no resemblance to a Seilrollenhubantrieb.

The oversized long and heavy design prevents normal, free running as with inliners, where the feet including sports equipment far from Can take off the ground. Because of the low ground clearance, running is over bumps life threatening with this construction. The designer has apparently more intermediate roles that an uncontrolled resting on the ground would avoid not scheduled.

problem

The until now designed drives for sports equipment, which by using dead weight and muscle power of the operator and a sports equipment moves forward were mostly too heavy, too big and in design the production too expensive. For drives on sports equipment such as z. As inline skaters or roller skates, etc., it comes on every gram Weight and a relatively small design in order to be able to deal with it safely and with good trade. There were also some Drives are not effective enough because their design has a lot of resistance and little propulsion generated.

The including sports equipment with cable drive to the aforementioned disadvantages have more technical problems.

Either is the rope end that for responsible for the drive revolution is too short or the construction does not include any other castors or wheels. Inliners preferably have 4 or 5 rollers to load while rolling out split into several roles, also ensure several roles the Tracking with little ground clearance on uneven road surfaces.

Solution of the previous disadvantages

Around the listed To avoid problems, I developed a pulley lifting drive.

This Pulley lifting drive is very light, relatively small, smooth, effective and uses the lifting height optimal. While a drive roller unrolls its rope and drives one or more drive wheels, her unrolled rope is simultaneously replaced by an extension pulley rolled up. The extension pulley is driven by a drive pulley.

By this brilliant idea stands for a drive pulley a multiple rope length available. The Tensile force, number of revolutions and acceleration time per operation can be controlled so unproblematically, optimally. Since the construction A from the outside movable from each side in the area of the other wheels or wheels Attached to construction b and a suitable space for the other Rollers or wheels If construction A is free between positions 1 and 2 move. It can This also several roles or wheels arranged in this position become. The size Ground clearance achieved in position 1 allows as well as in pos. 2, where all wheels or wheels touching the road, a sure, forward-looking forward movement on uneven, undulating roads. The light and relatively short Construction with all the advantages described allows a good deal with Inline skater and built-in pulley lift drive.

When running with inline skaters or similar sports equipment, in which a pulley lifting drive is installed, the respective user experiences the feeling ei Unusual, carefree moving forward.

Of the Pulley lifting drive is a drive that is mainly a Up and down movement with the use of its own weight and the necessary muscle power driven by the operator and mechanically by pulleys and the belonging to it Ropes and other required mechanical and technical parts in Connection with one or more drive wheels a sports equipment in motion puts.

Example:

When An example is the running process of an athlete with inline skater described in which the pulley lifting drive with a drive wheel is grown. If the athlete is running with these inline skaters lift one foot, a drive wheel moves mechanically controlled, that on the construction A fastened down, so that the drive wheel a clear greater distance to the lower edge of the foot Athletes occupy as the rest Wheels of the Inline Skarter. This is referred to as Pos. 1.

At the Placing the respective foot moves the drive wheel with construction A up to the height level the rest Skater wheels while driving the inliner.

is the drive wheel in height level the rest Skater wheels arrived, Pos. 2 is reached.

In This position can then lifted the respective foot with inliner again be attached so that the drive wheel to the construction A as described again moves down to pos. 1 of the mechanics again take.

One Pulley lifting drive is placed between its 2 moving construction parts A + B built in, characterized by the action of dead weight and the necessary Muscle power of the operator during one Move mechanically away from each other and approach each other again.

The structurally provided closest approach of the structural parts A + B is designated Pos. 1.

Of the Pulley lifting drive consists of at least one drive roller with freewheel and return spring, mounted on a drive shaft attached to construction A. is.

It now Pos. 1 is described.

In this position is the drive pulley with a corresponding Rope end pre-rolled to make the planned turn when unrolling to be able to.

At the Construction part B is a double pulley, positively connected for 2 separate Ropes mechanically connected to the drive pulley.

The Twin pulley is in an extension pulley and a translation pulley divided. In pos. 1, the rope end of the drive pulley is on the extension pulley ready to roll up.

The translation pulley has for enough for her work Rope rolled forward and is with its rope end to the construction A attached.

Becomes the pulley lifting drive by its own weight and necessary force set in motion of the operator from pos. 1, the construction points wander A + B apart.

The Drive pulley is by unrolling the pre-rolled rope in Rotation displaces and drives the drive shaft in this process at.

The Drive shaft in turn drives one or more drive wheels simultaneously, with which she is constantly connected mechanically and constructively.

The Extension cable pulley rolls a planned part of the unrolled rope end of the drive pulley at the same time to make more turns for the drive roller and the drive wheels to generate per stroke. The extension pulley is from the translation pulley driven, because this automatically rolls off, as her rope end on Construction part Pos. A is attached.

are the construction parts A + B diverge as planned, the return spring has become automatic curious; excited. Now Pos. 2 has occurred.

At the Relieving the mechanics and the pulley lifting drive is the Initial state restored. The whole mechanical process goes with the help of the freewheel and the return spring in the initial position 1 back.

Now everything can be repeated smoothly, rhythmically over and over again.
