Description

The invention relates to a roller board according to the preamble of Claim 1 or 2.

Similar roller boards, commonly referred to as skateboards have one as a common stand for footplate serving one user or one Tread plate on the underside of which rollers are mounted, whose axes are essentially parallel to the plane of the tread plate and run perpendicular to their longitudinal extension. Usually four castors are in the basic position on two Axles arranged parallel to one another rotatably, wherein at least one of the axes is opposite to the other below Exertion of force by the user in one plane in parallel Swivel to the step plate level by shifting weight leaves.

From US 4,795,181 is a modified in its basic construction Skateboard known that next to the two on the End of the footboard arranged a pair of rollers essentially central, much larger wheel and whose footboard is angled near this central wheel. This skateboard is a tricycle in every driving situation It is from the longitudinal shift of weight depends on the user which one is on the ends of the foot board arranged pairs of roles together with the central Wheel has ground contact.

From WO 95/27541 a skateboard is known, which one large central ball mounted in a horizontal axis of rotation, in the front area on a horizontal, fixed axis of rotation mounted pair much smaller Bullets and at the rear end a single, in a pivotable Has axis of rotation mounted ball. The ball suspensions and balls are dimensioned so that in horizontal Location of the footboard only the central ball has ground contact and by shifting the user's weight either the front wheel, the fixed pair of balls or the rear, steerable single Ball be brought into contact with the ground. With this construction should be maneuverability over a conventional Skateboard improves and the frictional resistance when Driving be reduced.

US 5,419,570 and US 5,601,299 are different Versions of so-called "inline skateboards" known in which several rollers arranged in a row one behind the other are. While the inline skateboard according to US 5,601,299 The skateboard has poles in the manner of ski poles according to US 5,419,570 a hoisted at the front end Handlebar that enables balancing. In the former, Skateboard maneuvered with sticks is in one special version instead of the front wheel one in a spherical ball bearing axleless ball provided. This version serves as a training device for increasing driving safety on demanding routes and terrain profiles.

From EP 0 500 991 B1 is a roller board for street "skiing" according to the preamble of claim 1 or 2 known. This roller board shows one after the other in neutral position arranged, a steerable front wheel and a track-proof Rear wheel on the side in the plane of symmetry sweeping as well as over the front and rear axles far protruding footboard. This roller board too is maneuvered with ski poles.

The invention is based, with regard to the task maneuverability and achievable driving speed and the realization of various types of sport Requirements for the user improved roller board of the generic type Specify type.

This task is solved by a roller board with the characteristics of claim 1 or 2.

The invention includes the essential aspect, a steerable front wheel axle on one opposite the vertical inclined forward and approximately at the height of the front axle to provide steering axle mounted on the chassis.

According to a further essential aspect, the invention closes the basic idea, essentially one arranged between the front and rear wheel axles Provide tread plate that is at least partially deeper lies as the highest point of the wheel circumference. According to this aspect are - compared to conventional skateboards - relatively large sized wheels in connection with a comparatively low positioned tread plate provided.

According to a first preferred embodiment, the front one or rear suspension on a wheel fork that the steering axis in the area of the front wheel guide or the rear wheel axle encompasses on both sides and in the chassis of the roller board holds. In a particularly practical version are here both wheel forks by two between the steering axle and the rear wheel axis and in an intermediate area frame tubes rigidly connected to each other. The rigid one Connection is made in particular through the tread plate itself or a carrier for one with the two Frame tubes, for example, welded or screwed is. Depending on the specific positioning of the step plate, in an additional one near the two wheel axles Connection between the two frame tubes may be provided. These can also go forward over the longitudinal axis or (in particular) reach back over the rear wheel axle and a portion of one in this protruding area continuous tread plate or a separate front or hold the rear step plate.

In an appropriate design, the front and rear wear Wheel axle each a single front or rear wheel, whereby these run in one track in neutral position.

In an alternative embodiment, the front one and rear wheel axle each a pair of front and rear wheels, the wheelbase in the rear wheel pair is much larger than is in the front wheel pair.

It is also a combination of these two designs insofar possible as a single, steerable front wheel with a pair of rear wheels combined in the manner of a tricycle chassis is.

In an alternative to the fork guide mentioned above or also combinable with one of the two wheel axles Execution of the chassis has the front and / or the rear wheel suspension has a one-sided wheel axle bracket on. In the special version in which both wheel suspensions are articulated on one side, are the articulation points in the area of the front and rear wheel axles on different Sides of the front or rear wheel or front wheel or rear wheel pair arranged. Supporting element of the Chassis is here in an appropriate design single frame tube, which is bent obliquely or S-shaped runs to the track of the roller board.

Also in this version of the chassis there are either a single wheel or on the front or rear axle a pair of wheels is provided.

In a snowboard-like driving style challenging and favoring execution of the roller board has the between the front and rear wheel axles Tread plate on a foot holder or binding, which by one Axis rotated perpendicular to the level of the tread plate is and its center in particular on the track of the roller board lies. When using the roller board, one foot becomes of the user is fixed in this binding while the other remains free to move and especially on one in the area extension of the tread plate located at the rear wheel axle or additional step plate can be put on.

The one between the front and rear wheel axles Step plate or the corresponding step plate section and / or the tread plate section located above the rear wheel axle or a separate step plate provided there can either be essentially horizontal or light be inclined forward.

If one is provided from the area of the steering axle (i.e. before the front wheel axle) up to the area of the rear wheel axle continuous tread plate this can be an immediate have a section lying behind the front wheel axle, which is tilted backwards a lot and a support for the user's front foot.

The steering wheel is especially in the single wheel version preferably a return element is provided, which the front wheel tends to return to neutral. In a simple execution it is a between Wheel guide and wheel fixed torsion spring element. In the This guide element is a version with a pair of front wheels possibly unnecessary, since a pair of wheels anyway when driving in pushes the neutral position back.

In view of the explosively growing market for Kick scooter or roller boards with a steering rod (kickboards) a corresponding embodiment of the roller board according to the invention particularly interesting when near the front Wheel guide (behind this) a handlebar or steering rod is arranged. This is in the middle level of the running board or the tread plate essentially perpendicular from this on.

If the step plate is inclined forward so he also prefers to lean forward a little. He can but also have a different orientation or, especially in the Execution as kick scooter handlebar, in its rising Part be angled. The storage or articulation of the Handlebar or steering rod is preferably slightly above that Step plate arranged.

1 to 3 shows a roller board 1 in an inline design a steerable front wheel 3 and a rigid rear wheel 5, which in a double tube frame 7 from a first frame tube 7a and a second frame tube 7b are guided. The frame tubes 7a, 7b are (seen in the direction of travel) in front of the geometric Front axle A1 welded to a steering head 9 and thus rigidly connected to each other here, and still they are about halfway between the front axle A1 and a rear axle A2 arranged first tread plate 11 as well as the entire rear wheel 5 and in the area of it largest extension also covering both frame tubes 7a, 7b second tread plate 13 connected to each other. The connection takes place according to Fig. 1 by screwing the frame tubes 7a, 7b with the tread plates 11, 13 over in the figure recognizing, but not separately designated holes in the Frame tubes, in the embodiment according to FIGS. 2 and 3 - where none Bores are shown - but z. B. by welding or Gluing the parts. The second tread plate 13 is otherwise over molded suitable supports on the rear ends of the Frame tubes 7a, 7b attached.

1 and 2 that the frame tubes 7a, 7b are cranked outwards in the region of the front wheel 3 to allow a sufficient steering angle of the front wheel. The first tread plate 11 essentially has one rectangular basic shape with a circular plateau area 11a, on the by means of bolts 15 a binding or foot holder 17 is screwed on, which is about the vertical center axis A3 of the plateau area 11a is rotatable. The second step plate 13 is - in some areas adapting to the rear wheel 5 - convexly curved and has an elongated central recess 13a. The frame tubes 7a and 7b and the plateau area 11a and thus also the bottom surface 17a of the binding 17th are in the embodiment shown here in the use position of the Rollboards horizontal.

4a to 5b are front and rear wheels and the front wheel Wheel guide of the roller board 1 based on sectional views and side views shown in more detail. The front wheel 5 has one, as can be seen in Fig. 4a and 4b inner wheel rim 3a and outer wheel rim divided in the center plane 3b on, easily rotatable with each other via a ball bearing 3c are connected. The outer wheel rim 3b has one Rubber or plastic tread 3d. The inner rim 3a is, as can best be seen in FIG. 4b, in adaptation to the shape and position of the steering head 5 in such a way that the wheel 3 via a (not shown) the steering head 9 penetrating in the longitudinal direction and on both sides of the steering head fastening axis engaging in the inner wheel rim 3a or via corresponding pin sections on the steering head is attached. As a return element for returning the deflected Wheel 3 in neutral is between the inner one Wheel rim 3a and the upper end face of the steering head 9 fixed torsion spring element 9a provided.

1 via a thru-axle 19 along the geometric Rear axle A2 held in the frame tubes 7a, 7b Rear wheel 5 is - as can be seen in Fig. 5a and 5b - as All-plastic wheel divided in a central plane. A ball bearing 5a is provided for rotatable mounting about the axis 19 provided, and the outer periphery is of an elastic Tread 5b covered.

6 is a sketch of a driving position of a user M. sketched on the roller board 1, in which this by appropriate Weight shift a side tilt of the roller board 1 and thus a steering lock of the front wheel 3 caused to the right. It can be seen that the right foot of the user M is fixed in the binding 17 during the left foot above the rear wheel 5 freely on the second step plate 13 is attached.

A roller board in the embodiment described above can driven without foot drive solely by shifting weight and providing one through weight shift Steerable front wheel in caster ensures a high Maneuverability combined with high driving stability, what - supported by the return element for the steered Front wheel - enables "flutter-free" driving. The in Compared to common skateboard wheels a lot wheels with larger diameters also allow a relatively fast and safe even on uneven ground Drive.

7 to 11 are overall views and cutouts of a roller board 21 in inline construction shown according to a second embodiment of the invention. A steerable front wheel 23 and a rear wheel 25 are hung and guided here in a chassis, the core of which is a single frame tube 27. The frame tube 27 runs as is clear in Fig. 8, obliquely to one by the Determine front wheel 23 (in neutral position) and rear wheel 25 Track S 'of the roller board 21 and is at the ends each bent towards track S '.

The front end of the frame tube 27 takes a steering head 29 on which a torsion spring element also in this version 29a to assist the return of the front wheel 23 in Neutral position is assigned. The steering head 29 is here as a total of approximately U-shaped part executed in the front Area is penetrated by the steering axis A4 'and there in a manner described in more detail below on the chassis is held and that in the rear area of the geometric Front axle A1 'is penetrated and there a front axle 30 of the front wheel 23 picks up. In the middle area between the front wheel 23 and the rear wheel 25 is also at this embodiment, a first tread plate 31 is provided a flat plateau area 31a for fastening a (here not shown) rotatable binding similar to that shown in Fig. 1 Has bond. At the rear end of the frame tube 27, the rear wheel 25 is guided via a rigid rear axle 32. Above the rear wheel 25 is a second tread plate 33 provided.

As can be seen in FIG. 7, this embodiment runs the frame, d. H. the frame tube 27, not horizontally, but climbs towards the rear wheel. At the front end of the frame tube 27 is its central axis below the geometric Front axle A1 'while its extension on the rear End is above the geometric rear axle A2 '. In this area is the frame tube 27 for receiving the rear axle 32 bent down again. Both the plateau area 31a of the first tread plate 31 - and thus also its central axis A3 '- as well as the surface of the second tread plate 33 are thus somewhat inclined.

9a and 9b and FIG. 11 are the front wheel and the there wheel suspension and in Fig. 10a and 10b the rear wheel shown in more detail. Both the front wheel 23 and that Rear wheel 25 are, as can be seen in these figures, here as all-plastic wheels with pronounced spherical and edgeless running surfaces running into the side surface. The axle bearing is carried out via a ball bearing 23a and 25a.

The principle of holding and guiding the front wheel 23 is in the synopsis of Figures 9a, 9b and 11 clearly. It it can be seen that the U-shaped steering head 29 in its front, approximately cylindrical area on the upper and lower End face of a fork attached to the frame tube 27 27a is encompassed, being between the upper end face of the (not separately designated) cylinder section of the Steering head 29 and the upper fork section fork 27a Torsion spring element 29a rests. This can be, for example with the lower surface of the upper fork part as well as the upper end face of the cylindrical portion of the steering head 29 be glued elastomer element that acts as a torsion spring works. The ends of the fork 27a, the cylinder section of the Steering head 29 and the torsion spring element 29a are one Threaded bolt 34 with (not shown) nut lengthways the steering axis A3 'penetrated and held together by this. In the area of the rear axle, as can be seen in FIG. 10a is, the frame tube 27 is an inserted solid end piece 36 on, in which the rear axle 32 is inserted and on which the rear wheel 25 is held on the ball bearing 25a.

The advantages mentioned above are also in this embodiment the first embodiment in substantially the same way given. In addition, the simpler frame construction enables saving weight and cost-effective production, and the latter version is also special agile and places specific demands on skill of the user.

12 to 14 is a third embodiment after the Tricycle principle built roller board 41 with a pair of front wheels 43, a pair of rear wheels 45 and a connecting both Central profile frame 47 (best seen in the bottom view acc. Fig. 13) shown. (The sketch according to Fig. 12 as well the bottom and side view acc. 13 and 14 differ in some design details, however, will be here regardless of one embodiment described.)

Basically analogous to the first and second embodiment, is the front wheel pair 43 with the geometric front axle A1 '' via a steering head 49 with a geometric steering axis A4 '' mounted on the frame 47 in the follow-up guide. The steering head 49 is here via a mounting plate 49a with the central profile frame 47 screwed. On one through the steering head 49 held front axle 50 are the front wheels 43a, 43b in short distance of less than one wheel width over (not shown) ball bearing rotatably mounted.

The central profile frame 47 has, as best in FIG. 14, too is recognizable, a flat in the rear and middle area and forward inclined surface and shows in the front area, above the front pair 43, several bends in the form of a crank so that it is the top of the pair of front wheels 43 surrounds relatively closely. Over the entire length of the Frame 47 is continuous and conforms to the shape of the frame 47 angled footboard 51 provided that a straight, perpendicular to the axis of symmetry Has trailing edge and tapers streamlined towards the front. A rear axle 52 on which the rear wheels 45a, 45b are attached at a relatively large distance is via a rear axle suspension 53 and an associated mounting plate 53a attached to the central profile frame 47.

The third embodiment also essentially has the advantages mentioned above compared to conventional skateboards on, but is stronger than that described above Designs on their basic shape and driving characteristics oriented. The continuous running board enables a practiced Skateboard users deal with this skateboard without it fundamental change of driving technique.

15A to 15C is the fourth embodiment of the invention a constructively essentially the third embodiment corresponding kickboard variant of the invention Rollboards shown. With the third embodiment 12 to 14 essentially (apart from modifications in the dimensions or in the design) Parts are based on the third embodiment Designated reference numbers. These parts are not here explained further. The main difference is in the existence a steering rod 54 having an outer tube 54a and a adjustable in height and by a locking ring 54b includes fixable inner tube 54c with a steering knob 54d.

in einem mit diesem verschraubten Rahmenelement 55, welches die Trittplatte 51 mit der Führung des Vorderradpaares 43 verbindet, ein Lenkstab-Haltestift gehaltert ist, und zwar etwas oberhalb der Ebene der Trittplatte im vorderen Bereich.15c that above the level of the actual running board 51st

in a frame element 55 screwed to this, which the tread plate 51st with the guidance of the front wheel pair 43 connects, a steering rod holding pin is held, and something above the level of the tread plate in the front area.

With the steering rod 54, the roller board can be moved as a kickboard, with the advantages of caster guidance mentioned above the front wheels also come into play here in a favorable way.

The implementation of the invention is not based on those described above Examples limited, but also in a variety of modifications possible within the framework of professional action lie. In particular, there are appropriate combinations of Features and elements of the described embodiments within the scope of the invention.
