Definitions
- the invention refers to an undercarriage for a roller skate or a skateboard / scooter board with at least one steering axle which pivots on a swivelling axis provided in a retaining framework.
- the swivelling axis slants in or against the direction of travel.
- an undercarriage (AT 005006 U1 ) exists with at least one steering axle pivoted on a swivelling axis provided in a retaining framework.
- the swivelling axis slants in or against the direction of travel and goes with a radial distance to the steering axis. Due to the slant of the swivelling axis, a swivelling of the foot board around a longitudinal axis causes an additional swivelling adjustment of the steering axle that is supported on the ground by wheels on both sides, around an axle which is positioned in vertical position to the ground, resulting in a corresponding deflection of the steering mechanism.
- the invention is intended to provide an undercarriage design of the above mentioned kind that is aimed at an importantly reduced overall width and road performance, mainly comparable to a one track undercarriage.
- the invention solves this problem in the way that the swivelling axis, which is integrated in the steering axle, is arranged on a support forming part of a bearing fork.
- the support is axially retained in the steering axle in a recess which is vertically positioned to the swivelling axis and provides clearance for the steering turn. Since, due to these arrangements, the swivelling axis within the steering axle is arranged on a support, which is axially retained in the steering axle, the steering axle can be of reduced length, since it is required to only take up the bearing of at least one wheel that encloses the steering axle and the swivelling axis and is integrated in the bearing fork for the support of the swivelling axis.
- the recess in the steering axle for the retention of the support of the swivelling axis must, however, allow a horizontal-swing of the support determining the deflection of the steering mechanism in relation to the steering axle.
- a simple, narrow overall width results for the undercarriage which allows it to be used not only for skateboards / scooter boards, but also for roller skates.
- the overall width is mainly determined by the width of its rest.
- the overall width is mainly determined by their axial distance.
- the width of the wheel rest and the axial distance of the wheels respectively are dictated by the support of the steering axis on the ground needed for the steering and for tilt resistance. This can already be achieved with a comparably short wheel width or a small distance of the wheels, thereby achieving a road performance that can otherwise only be achieved by one-track undercarriages.
- the wheel coating may exceed the axial length of the steering axle, thus the wheel coating juts out on both sides over the face of the steering axle.
- the reduced length of the steering axle, which is set back to the wheel coating allows, in spite of its restricted diameter, enough steering movement in relation to the support which is retained in the steering axle within the provided clearance between the support of the steering axle and the steering axle recess taking up the support.
- the geometrical axes of the swivelling axis and the steering axle may cut across each other.
- Such an arrangement can do without the reset forces during a steering action, whereas of course, the corresponding reset forces can be provided, for example by spring elements between the support for the swivelling axis and the steering axle.
- the drawing shows an example of the object of invention.
- FIG. 1 an undercarriage according to the invention for a roller skate in a simplified, partial cross section view Fig 2 a larger scale profile of the undercarriage in the area of the swivelling axis Fig. 3 a section according to line Ill-Ill of fig. 2 Fig. 4 a front view of a wheel and its running carriage according to the invention in steering lock position Fig 5 a skateboard / scooter board with an undercarriage according to the invention in a simplified lateral view
- the undercarriage assembled on a roller skate 1 shows a retaining framework 2 that takes up a front and rear wheel 3.
- These wheels consist of a wheel body 4 with a basically cylindrical coating 5 of elastic rubber material.
- the wheel body 4 pivots by means of two bearings 6 on a steering axle 7, which itself can be swivelled around a swivelling axis 8.
- the steering axle 7 retains the swivelling axis 8 in the bushings 9.
- the swivelling axis is assembled on a support 10 which is retained in the steering axle 7 in a recess 11 vertically positioned to the swivelling axis 8 while providing sufficient clearance to swivel steering axle 7 around the swivelling axis 8 for a steering turn without obstruction by support 10.
- Support 10 itself is retained in the • lateral sides 12 of a fork 13 forming part of the retaining framework 2. Since the swivelling axis 8 slants in relation to the direction of travel, as especially illustrated by fig.
- a horizontal-swing of the retaining framework around an axis going in the direction of travel causes a swivelling adjustment of the steering axle around the swivelling axis 8, since the steering axle 7 which is supported on the ground by means of wheel 3 cannot join in the swivelling movement of the swivelling axis 8 which is fixed on the support.
- the only possible compensation of movement is a turn of the steering axle 7 around an axis positioned vertically to the ground as graphically illustrated in fig. 4.
- a steering movement, for the front as well as for the rear wheel 3, can be produced by a bending movement to the sides of the retaining framework 2 by means of the roller skate 1. It is probably unnecessary to particularly stress that not both wheels 3 have to be supported on a steering axle.
- an inclination to the sides of the retaining framework 2 must be provided. This can be guaranteed by an unguided wheel that allows an inclination to the sides or by a wheel that is supported with limited swivelling clearance in relation to the support around an axis in the direction of travel.
- wheel 3 of each steering axle 7 could be replaced by two conventional wheels, the axial distance of which corresponds with the length of the contact area of the cylindrical coating 5 of one single wheel 3.
- the use of the undercarriage according to the invention is not only restricted to roller skates. Undercarriages according to the invention can also be used with advantage for skateboards / scooter boards where the stepboard 14 is provided at both ends with a steering axle 7, as described above.
- the undercarriage is formed by two separate retaining frameworks 2 that are fixed to the bottom side of the stepboard 14 and form a fork to carry the support 10 as described in correlation with fig. 1 to 4.
