Abstract

The invention relates to a single-track scooter vehicle for locomotion in mountainous terrain, which has a support element (4), in particular for the knee and / or shin, which is also designed as a backpack element. The design of the rolling vehicle enables quick transfer from the operating position to the transport position and vice versa, the rolling vehicle allowing safe departure (3-5) or scooter ride (2) in the operating position and due to its low weight and small dimensions in the transport position can be easily carried along (1). The carrying / stowing / supporting element (4) of the scooter vehicle can also be used as a storage space in the manner of a rucksack.

Description

Critical consideration of the state of the art:

By the AT 409754 B is a "sports equipment for locomotion in Alpine terrain" known in which walking sticks are used as a steering device in a scooter-like vehicle. The integration of the poles prevents their own habitual hiking poles to use, also the sticks must be made massive by the double use, this leads to a high weight of the poles compared to conventional hiking poles. The Guided is unsprung and equipped with very small wheels, so it is hardly off-road and can only be used on very well-developed trails.

By the DE 19508047 A1 is a "non-powered wheeled vehicle for driving off slopes" known in which a sitting or lying driving position comes to bear. It is equipped with three wheels, which inevitably leads to a higher weight compared to a two-wheeler, as well as tilting when cornering to the inside of the curve not possible or only with technical extra effort. A sitting / lying driving position makes it almost impossible to react quickly and agilely to obstacles. In addition, back-friendly driving off on rough ground is not possible in this situation.

Furthermore, a is known in DE 29516837 U1 described "two-wheeler for mountain descents". The construction comes close to a scooter. The frame is designed as a footboard as a truss-like connection with both sides mounted footrests. The vehicle is designed to be pivotable about the pedal axle hinged. For the uphill transport of the two-wheeler, which is not exactly compact when folded, there is no solution.

After DE 10 2006 012 938 A1 is a "scooter with at least one laterally folding tread unit" known. The geometry is similar to the one in DE 29516837 U1 , but with a sprung suspension. Although the two-wheeler described here is foldable or foldable, a transport on the back was not considered, which was represented by the bulky design, even in the folded state, as very difficult.

Common to the acquaintances of downhill suitable companions is the disadvantage that they do not provide a total system solution, off-road, comfortable and safe vehicle, combined with a skilful stowage and carrying system and at the same time weight-optimized, as a prerequisite for such a means of transportation.

Tasks:

The present invention is therefore an object of the invention to provide a single-track scooter vehicle for locomotion in mountainous terrain, which is suitable for safe, healthy and fun-intensive locomotion in mountainous terrain, while gently rising, flat and sloping tar roads, forest roads, gravel roads, paths, Trails, cart paths and the like can be traveled.

The present invention is further based on the object to provide a vehicle that can be compressed quickly and easily and is combined with a back carrying system, the highest level of comfort offers to carry this even in tight spaces, comfortable over longer distances and rough terrain away to be able to. This ensures the effortless change between running and rolling, which makes efficient and varied movement in mountainous terrain possible.

Another object of the invention is to provide a sports equipment that can be created with a minimum of cost and very low weight.

Solution:

These objects are inventively achieved in that the Rückentrage- and stowage system is combined according to claim 1 with the scooter vehicle, while the back part of the support member at the same time a knee or knee and shin pad there.

The design of the trolley allows a quick transfer from the operating position to the transport position and vice versa, the trolley in the operating position safe downhill ( 3 to 5 ), even in rough terrain represents, or scooter ride ( 2 ), in a level slightly ascending or sloping terrain and in the transport position ( 1 ) can be easily carried by the low weight, the close storage and the small dimensions.

The descent is possible depending on the terrain, gradient and personal preferences in different positions. On the one hand, a standing position ( 3 ) taken in which shocks are bounced in uneven terrain by bending the knees. On the other hand, it is possible to assume a knee position by placing the knees, or knees and shins, on the support element. In this case, hardly any body tension is necessary, in addition, the upper body is approximately horizontal and thus back-relaxed position. The thighs can on the one hand the lower legs are stored ( 5 ), but also be positioned horizontally ( 4 ).

Further embodiment of the invention:

The frame ( 1 ) of the vehicle is fixed or via a clamping mechanism ( 14 ) detachable on the carrying element ( 4 ) attached. The control head ( 13 ) protrudes at the top of the support element ( 4 ) or is integrated in this. The frame ( 1 ) is the carrying system ( 4 ) hinged, foldable, dismantled and / or pluggable designed.

For example, the frame ( 1 ), be carried out according to claim 3, at least two parts and are telescopically compressed, he receives this purpose a main pipe ( 11 ) and a rear triangle ( 12 ). For this, the rear triangle ( 12 ) from the main pipe ( 11 ), via a quick release device and after or without removal of the rear wheel ( 3 ) into the main pipe ( 11 ), whereby it is possible that the rear triangle ( 12 ), according to claim 5, first from the main pipe ( 11 ), rotated 90 degrees and after or without removal of the rear wheel ( 3 ) is reintroduced, so that the rear wheel ( 3 ) is approximately plane-parallel to the back part. By this way of reducing it is possible, with minimal effort, the frame ( 1 ) extremely stowable and close to the carrying element ( 4 ), which represents a high wearing comfort.

To the frame ( 1 ) can stow even more compact the main pipe ( 11 ), are mounted laterally on the control head according to claim 6 ( 16 ), so that it is open to the front and the interior of the profit is consistent, so a telescopic element can be pushed through until it protrudes on the steering head side. In such a design of the frame ( 1 ), the rear fork must be either at the same distance to the center, or at an angle to the frame ( 1 ) are attached to the front wheel ( 2 ) and the rear wheel ( 3 ) in a lane.

According to claim 7, it would be possible in principle, the rear wheel ( 3 ) not on a fork, but the rear hub only on one side of the frame ( 1 ) or rear triangle ( 12 ). Further, such a frame profile, which can be made telescopic, parallel or approximately parallel to the wheel track from the rear wheel to the control head ( 13 ), which can then be attached laterally to the frame profile, lead.

Preferably, the telescopic frame member consists of hollow profiles to optimally absorb the torsional load. According to claim 4 square tubes or square tubes with radius, which prevent the rotation of the tubes without additional design effort by positive engagement can be used.

The frame ( 1 ) could also by a hinged joint, known in folding bicycles, about an axis parallel to the control head ( 13 ) or slightly angled to the control head ( 13 ) and in the middle of the frame ( 1 ), be worked out. Through a joint, which is mounted parallel to the rear wheel axle or slightly angled to the rear wheel axle, can / could the rear triangle ( 12 ), with or without rear wheel ( 3 ) from the front to the front side of the carrying / stowing / supporting element ( 4 ) are folded.

The frame ( 1 ) or rear triangle ( 12 ) can be carried out both rigidly and sprung. In the case of a sprung version via a rocker, the joint of the rocker can be used both as a spring joint and as a folding joint.

The carrying / stowing / supporting element ( 4 ) can provide additional storage space for accompanying equipment and food in the manner of a backpack, or serve only to transport the scooter companion. In both cases, it may be specially modified for stowing or attaching the individual components of the companion, for example by mounting brackets for attaching an impeller and / or openings for inserting the fork ( 5 ) and / or the rear triangle ( 12 ) or frame ( 1 ) having. According to claim 15 is on the backpack base a zipper that towers on both sides of the backpack and approximately in a plane that is parallel to the back, attached. The rear triangle ( 12 ) can thereby without removing the rear wheel ( 3 ) close to the carrying / stowing / supporting element ( 4 ). The knee and / or shin pad, as well as the back, are designed according to ergonomic considerations.

The front wheel ( 2 ) can with fork ( 5 ) to the carrying / stowing / supporting element ( 4 ) by folding the front wheel ( 2 ) transversely and by a lockable folding joint, known from folding bicycles for folding the handlebar assembly, which is according to claim 16 above the fork crown ( 19 ), to the front side of the carrying / stowing / supporting element ( 4 ) is folded down. The fork ( 5 ) can be designed as a fork.

Substituting a parallelogram suspension fork, it is possible to use one of the spring joints of claim 17 as Einschwenkgelenk the fork. This happens by a joint axis ( 21 . 22 . 23 . 24 ) of the fork by a quick release, known as Acherspannverschluss for wheels, is released from the respective rocker (s) and the fork is rotated without or after removal of the impeller to the frame member. To release the joint axes can also be Quick-release fastener which clamps the fork crown with the respective axle. Example becomes in 9 the articulation fork fork single swing ( 22 ), then the fork spar ( 20 ) counterclockwise about the joint axis fork crown double rocker ( 23 ) is pivoted towards the frame element ( 10 ). For this pivoting movement, the joint axis can / could also be the fork crown single rocker ( 21 ) instead of fork spar ( 22 ) are solved. To mount the individual wings ( 25 ), these can be rigidly interconnected. If you choose the joint axis Gabelkrone-Doppelschwinge ( 23 ) ( 11 ) as the axle to be released, so the fork can be clockwise to the storage fork crown single swing ( 21 ) and about the free joint axis Gabelholm-single swing ( 22 ) to the front of the carrying system. The bearing holes of the fork wings ( 25 . 26 ), which are located on the joint to be solved, are designed according to claim 18 slotted ( 8th ). To facilitate the mounting and dismounting of the fork wings ( 25 . 26 ), the slot flanks can be inclined towards the bearing hole according to claim 19. This Einklapp principle of a parallelogram suspension fork can be used in all companions. For example, this mechanism can also be found in folding wheels or other two- or Mehrradkonzepten, both with and without removal of the impeller, application.

The handlebar body made of head tube ( 9 ) and handlebars ( 8th ) or head tube ( 9 ), Handlebars ( 8th ) and stem ( 7 ), can through the shaft tube ( 15 ), after removal or folding away the front wheel 2 , lowered down until the handlebar ( 8th ) slightly lower than the back part of the carrying / stowing / supporting element ( 4 ) stands. The driver ( 8th ) can be rotated about the control axis, for example by 180 °, or remain in the same driving position.

To the head tube ( 9 ) to solve or fix, the shaft tube ( 15 ) the head tube ( 9 ), lock in the manner of conventional seat post clamping.

Instead, the shaft tube ( 15 ) are slotted at the bottom or in the lower area at least once and by spreading the head tube ( 9 ) are clamped from the inside in the slotted area. This is done, for example, by a mechanism known from fork steerer extension adapters. It is about a clamping axis ( 18 ) an obliquely separated wave piece ( 17 ) against an inclined surface at the same angle of a pipe section ( 16 ), which is located inside the head tube and is fixedly connected to it, pressed ( 12 and 13 ). Due to the obliquely superimposed surfaces creates a radial force, the control tube ( 9 ) aufspreitzt and to the inner wall of the shaft tube ( 15 ) presses. The clamping axis ( 18 ) can above the head tube ( 9 ) are tensioned by a quick release, which is mounted eccentrically in the manner of a seat post quick release. According to this principle of clamping, the control tube ( 9 ) are separated even at its bottom obliquely and the obliquely separated shaft piece on the clamping axis ( 18 ) directly to the inclined surface of the head tube ( 9 ) are pressed and so a radial force on the shaft tube ( 15 ), which the control tube ( 9 ) is stuck.

The handlebar assembly can also analog conventional Faltradkonstruktionen after releasing a hinged joint, about an approximately perpendicular to the control axis storage, located above the control head ( 14 ), to the carrying / stowing / supporting element ( 4 ) are pivoted.

On the frame ( 1 ) are on both sides footrests or pedals ( 10 ), these may be rotatably mounted or have a standing approximately parallel to the ground tread surface and / or an inclined tread, which is ideal for driving in kneeling or squatting position ideal. They can be fixed, removable or folded to the frame. If one selects detachable pedals, then on the frame ( 1 ) Latching elements are mounted in order to fix them in the transport position.

The low center of gravity coming from the low-mounted pedals ( 10 ) and the kneeling driving position results in good stability and maneuverability, both in straight and cornering. Because the side treads ( 10 ) very far back, just in front of the rear wheel ( 3 ), an extremely far rearwardly displaced center of gravity is achieved, which allows to ensure a high braking effect without risking the risk of a frontal rollover. This downhill geometry, with the center of gravity shifted far to the rear, results in a stable, safe and intuitive driving concept.

In order to be able to regulate the speed of the sports equipment, a brake acts on at least one running wheel. A brake, known as a V-Break, can be installed in such a way that the frame ( 1 ) mounted brake bearing as a supporting element, acts and / or is not bolted to the frame, but within a profile ( 17 . 18 ) or between two sheets ( 19 . 20 ) is attached. This can for example be realized by the brake bearing is mounted between a U-profile, as it 17 and 18 demonstrate. To incorporate this type of brake further brings the advantage of protecting the brake from collisions with other objects when inserted into the backpack, which could lead to the adjustment of the brake.

The choice of wheel sizes is the ideal compromise between off-road capability, while the largest possible wheels make it possible to discuss the optimum and compactness of the system. For example, the use of different sized wheels to a good compromise to create a vehicle with high driving safety, which is designed as compact as possible in its design. So, as a rear wheel ( 3 ) a slightly smaller impeller are installed, this has the advantage of reducing the missing slope to the actual slope. The slightly larger front wheel ( 2 ) ensures track stability of the sports equipment by rolling over obstacles easily.

To improve ride comfort in squatting driving position ( 1e ), a buttock support on the frame ( 1 ) or rear triangle ( 12 ). It can, for example, by the Acherspanner the rear wheel ( 3 ), so that the buttocks support when releasing the clamping around the wheel axle to the frame ( 1 ) or rear triangle ( 12 ) can be swung out.
