Description

Roller board

The invention relates to a roller board with an elongated footboard and with arranged at its front and rear end, provided with castors which are steerably attachable to the footboard, wherein a lateral movement of weight by the person standing on the footboard, a steering movement can be transmitted to the axles .

Known roller boards of the type mentioned are known under the category "skateboard". In skateboards, the axles provided at the front and rear ends each have two lateral rollers on which one can stand up by pushing off the ground with one leg or by means of a special technique of alternating pressure of both feet can move to the outside of the skateboard by shifting weight.

From DE 20 2010 010 576 Ul, for example, a skate board is known which, due to its material properties and shape of the base, can be used in a targeted manner to enable deformability which, when the weight is shifted, leads directly to a steering movement of the wheel axles attached to the base . The steering option is very limited in this construction.

Another skateboard is known from DE 10 2010 034 908 Al, which already has a flexible steering option Has axes. The restoring force that returns the axles to the central position after the steering process is applied by a metal torsion spring, one leg of which is firmly connected to the running board, while the other leg acts on the respective axle. However, such a mechanism is structurally relatively complex and difficult to effect.

The invention is therefore based on the object to provide a rolling board in the manner of a skateboard, which with very simple means enables improved maneuverability and easier operation.

According to the invention, this object is achieved in that

that an essentially rigid boom is provided at the front and rear ends of the running board,

that on each arm a support arm pointing in the direction of the central axis of the footboard is rigidly attached, that on each support arm there is a hub which is inclined by 40 ° to 50 °, preferably about 45 °, with respect to the plane of the footboard in the direction of travel Swivel axis is pivotable to both sides, and that in or on each hub, the axis of a single roller is rotatably mounted, the swivel joint is located inside the respective roller.

The new steering mechanism allows the roller board according to the invention, which differs considerably from known skateboards, to be steered very easily by shifting the weight, with both the rear roller and the front roller swiveling to the side in question, which due to the shift in weight of the operator toward un th is pressed. Furthermore, the two casters, which are arranged in front of and behind the footboard and can have a relatively large diameter, allow a comfortable one Driving, with good driving behavior guaranteed even on poor road surfaces and minor obstacles.

The substantially rigid arms, which are attached in front of the front and behind the rear end of the running board, are expediently arranged on the same side of the running board.

It is also possible to make the angle of the boom adjustable in the vertical plane relative to the level of the running board, so that influence on the height of the running board above the ground and on the driving behavior of the rolling board can be exerted.

The roller provided at the front and rear end of the footboard can not only have a relatively large diameter, but is also expediently designed to be relatively wide, approximately as wide as the footboard, so that safe and comfortable driving behavior is made possible. The outer edges of the rollers act as a lever when the weight is shifted and steer the roller board in the desired direction.

The hub provided on each support arm, which is used to support the respective roller, can be hollow.

In a first embodiment, the support arms are ga-shaped, with mounting holes being provided on the fork ends of the support arms, while pins are formed on the inside of the hollow hubs, which engage in the mounting holes of the fork ends.

Alternatively, the pins can of course also be provided as an equivalent on the fork ends, while receiving bores are formed on the inside of the hollow hubs into which the Engage the pin of the fork ends.

In another exemplary embodiment, the likewise fork-shaped support arms can have receiving bores at the fork ends, while pins are provided on the outside of the hubs, which engage in the receiving bores of the fork ends. The axes of the Laufrol len can be stored in the hubs. In this embodiment, for example, the pin and the mounting holes can be exchanged.

In a further embodiment, a steering head which is offset by approximately 45 ° with respect to the running board can be provided on the outer side of the axles, the steering heads being pivotally connected to the support arm.

In a further exemplary embodiment, the end of the support arm can be designed as a ring which engages around a cross pin provided in the interior of the hub.

In a further embodiment of the invention, a roller bearing can be articulated on each support arm, the inner ring of the roller bearing being pivotally connected to the support arm and forming the fixed hub, while the outer ring of the roller bearing serves as the rotating axis of the roller.

In the latter embodiment, a cross pin is expediently attached to each support arm, which engages pivotably in radially opposite bores of the inner ring of the rolling bearing.

Ball bearings are preferably used as rolling bearings.

All embodiments of the roller board according to the invention can be provided at the front end of the footboard with a vertical, removable handle, by the more Safety and comfort when driving is guaranteed.

A motor can be arranged inside at least one of the rollers, the output shaft of which drives the axis of the roller. The motor can be operated via a remote control or a controller provided on the handle.

According to FIGS. 1 and 2 of the drawing, the roller board according to the invention consists of an elongated footboard 1 and rollers 2 and 3 arranged in front of and behind its front or rear end.

To hold and mount the rollers 2 and 3 are at the front and rear ends a front and rear ge, essentially rigid boom 4 and 5 respectively. On each of the arms 4 and 5, a support arm 6 or 7 pointing in the direction of the central axis of the running board 1 is rigidly attached. In the illustrated embodiment, the boom 4 and 5 are arranged on the same side of the footboard.

On each of the two support arms 6 and 7, a hub 8 is easily seen, which is about a 45 ° to the plane of the

Running boards 1 in the direction of travel inclined pivot axis 19 is pivotable to both sides, as shown schematically in Fig. 2. The hub 8 is connected to the respective support arm 6 or 7 via a swivel joint 9 such that it can be swiveled in both directions to the plane of the running board 1 by approximately 25 °.

As can further be seen from FIG. 1, at the front end of the running board an approximately vertical holding handle 10 reaching to the belly height of the person standing on the running board 1 can be provided, which can optionally be attached to or removed from the running board 1. By attaching the handle 10 can be achieved under safe and comfortable driving for the operator.

As can also be seen from FIGS. 1 and 2, there is only one at the front and rear end of the running board 1 Roller 2 or 3 is provided, which is relatively wide and preferably has approximately the width of the footboard 1. The rollers 2 and 3 are expediently cylindrical, but deviations are possible, for example, a slightly spherical or flattened shape can be selected to the side edges. The arms 4 and 5 are substantially rigidly attached to the footboard 1, a slight pivoting movement can be generated by the elasticity of the material. There is, however, the possibility of adjusting the angle of the two arms 4 and 5 in a vertical plane relative to the plane of the running board 1, so that the height of the running board 1 can be changed relative to the rollers 2 and 3.

As can be seen in particular from FIG. 2, a lateral movement of weight by a person standing on the running board in the direction of arrow 11 can transmit a steering movement to the axes of the rollers 2 and 3. If the running board tilts to the left, as shown in FIG. 2, the front roller 2 also pivots to the left and the rear roller 3 to the right, so that the roller board travels to the left.

In the following figures, various Ausführungsbei games for the pivot joints 9 between the support arms 6 and 7 and the respective hub 8 are illustrated.

3 and 4, the front end of the footboard 1 is provided, to which the boom 4 is rigidly attached. At the free end of the boom 4, a fork-shaped support arm 12 is rigidly attached, on the fork ends 13 receiving holes 14 are formed. The two fork ends 13 of the support arm 12 overlap a hollow hub 15, on the outer circumference of which pins 16 are formed on opposite sides, which engage in the receiving bores of the fork ends 13.

The axis 17 of the roller 2 is inside the hollow Hub 15 stored. The axis 17 is connected to the roller 2 via a plurality of struts 18 distributed over the circumference.

The fork-shaped support arm rigidly attached to the boom 4

12 is arranged such that a plane running through the fork ends 13 is inclined approximately 45 ° to the horizontal.

So if the footboard 1, as shown in Fig. 2, is inclined to the left, the pivotable on the fork-shaped support arm 12 also rotates the hub 15 slightly to the left and takes the axis 17 and thus the roller 2 with it.

In Fig. 5, the steering mechanism of the embodiment ge according to FIGS. 3 and 4 is shown again schematically. It can be clearly seen that the pivot axis 19 extending in the direction of the pins 16 is inclined by approximately 45 ° to the vertical or horizontal.

On the right side of FIG. 5 is a schematic view of the inner region of the swivel joint in the direction of arrow V, which clearly shows that the forked support arm 12 engages over the hollow hub 15 and the hub 15 through the through the receiving holes 14 Hing pin 16 is pivotally gela between the fork ends 13.

In Fig. 6, an analog steering mechanism to the embodiment example of FIG. 5 is shown. The difference to the embodiment according to FIG. 5 is that the fork ends

13 engage in the interior of the hollow hub 15 and create a pivotable connection between the fork-shaped support arm 12 and the hub 15 via the pin 16.

The axis 17 of the roller 2 is in this case on the outer periphery of the hub 15 is mounted and is connected to the roller 2 via struts 18. A view of the central region of the roller 2 in the direction of the arrow VI is shown on the right side of FIG. 6.

7 and 8 a further embodiment of the swivel joint of the roller 2 is shown. In this exemplary embodiment, a steering head 20 is provided on the outside of the hollow hub 15, which is offset by approximately 45 ° with respect to the footboard plane. The steering head 20 is pivotally connected via a joint 21 to the support arm 6 rigidly arranged on the arm 4. The axis 17 of the roller 2 is mounted half inside the hollow hub 15, the axle 17 via struts 18 being connected to the roller 2.

9 and 10 a further embodiment of the swivel joint in the front roller 2 is shown. The roller 2 is mounted on the boom 4 and the support arm 6. The support arm 6 has, at its end located inside the roller 2, a ring 22 which surrounds a bearing pin 23 extending transversely through the hub 15. Between the ring's 22 and the bearing pin 23 there is a sliding sleeve 24. The axis 17 of the roller 2 is rotatably supported on the hub 15 and is connected via struts 18 to the roller 2. The bearing pin 23 is approximately 45 ° to the plane of the footboard 1 inclined. 11 and 12 show a further exemplary embodiment of the invention, which in principle is very similar to the exemplary embodiment according to FIGS. 9 and 10.

In this embodiment, the arm 6 seated on the boom 4 has at its inside the roller 2 be sensitive end a firmly connected to this cross pin 25, which in turn is inclined by approximately 45 ° with respect to the plane of the running board 1. This cross pin 25 serves as a pivot axis for the hub 15. The pivotability is achieved in that the cross pin 25 engages in corresponding La ger bores, which are provided in the inner wall of the hub 15.

The axis 17 of the roller is rotatably supported on the hub 15 and connected to the roller 2 via struts 18.

13 and 14 show a further exemplary embodiment of the invention, specifically in this case the swivel joint is constructed with the aid of a ball bearing 26, the ball bearing 26 having an outer ring 27, an inner ring

28 and a plurality of balls between the two rings
