Description

Roller bearing for skating equipment

Technical field

It skates for centuries and has been known dawn, and leisure, movement and the body-building for being referred to as preferred of skating Activity.Roller bearing skating is to simulate and skate and create on solid ground.First item ice skate are referred to as double-row type and slip Skating boots (quad skate).Double-row type ice skate have four wheels for lining up two rows.Double-row type ice skate unlike skate so It is fast and flexible but still popular to people in six the seventies.The new era of roller-skating starts from the nineties, at that time straight-line family Outer roller skates is led to masses.Straight-line ice skate are faster and more more flexible than double-row type ice skate, but experience still incomplete Similar to skating.Straight-line ice skate have no chance to stop (hockey stop) and braking of breakking away using hockey.

Several trials have been made to be further improved straight-line ice skate.

For US 6,508,335 (B2) characterized by omni-directional wheel, which includes: frame, which has for by frame Be attached to the upper part of the following side of load bearing surface, at least two side walls and by side wall limit for receiving at least one ball The central chamber of shape wheel；At least two wheel load-bearing parts, the wheel load-bearing part is axially aligned with side wall to be connected for making wheel around solid The rotation of dead axle line；At least two wheel seats, the wheel seat respectively have with wheel carriage shaft to a side of connection and opposite Tapered surface, wherein tapered surface with it is opposite it is axially aligned be arranged for take turns be mounted between these faces, and surrounded in wheel Stiction is applied relative to tapered surface and wheel when fixed axis rotates, and surrounds the axis vertical with fixed axis in wheel Kinetic force of friction is applied relative to tapered surface and wheel when rotation；And it is connected to the upper load carrying member of frame, load is held on this Holder is biased against the upper surface of wheel.

For US 5,397,138 (A) characterized by straight row type roller skate, which includes elongated base Plate, the elongated substrate have the following side of four wheel assemblies of the top side portion for being fixed with boots and installation, and there is front component fixation to take To and remaining component respectively there is foot wheel-like structure.Spring by each foot wheel assemblies in foot wheel assemblies along straight line forward Orientation biasing, and first exists close to vertically extending fixation brake area and second close to vertically extending fixation brake area It is spaced apart in the opposite side of wheel after, as soon as so that wheel rubs when wheel substantially turns to a direction or opposite direction Engage brake area.

Detailed description of the invention

Hereinafter, exemplary embodiments of the present invention are described with reference to the accompanying drawings.There is provided these examples with to A further understanding of the present invention is given, rather than limits range.

In the following description, a series of elements are described.It will be appreciated by those skilled in the art that unless being referred to by context Fixed, otherwise the number of element or position are not crucial for final configuration and its effect.

Fig. 1 shows the schematic cross sectional views of the roller bearing 20 of an embodiment in embodiment according to the present invention, Roller bearing 20 includes wheel shaft 25, ball bearing 30 and surface 22.Skating equipment 1 (Fig. 3) may be adapted to provide to skater certain In degree with skating and/or the comparable experience of roller bearing skating.In order to realize this experience, which is adapted to allow for spin 15 in institute Have and rotated on direction, wherein friction depends on the direction of rotation of spin, wherein minimized friction can skating equipment 1 to Before/backward directions on, and maximum friction is on the direction perpendicular to forward/backward direction.Roller bearing 20 is by spin 15 (Fig. 3) In It is maintained in skating equipment 1 at the position of spin 15.Single spin 15 (Fig. 3) can be at least at a point, preferably two It is contacted at a point with the roller bearing 20 with generally concave shape.In this embodiment, roller bearing 20 is to abut with ball bearing Mode is placed on wheel shaft.It should be understood, however, that any other bearing is acceptable.For example, fast pulley can be set The rotary motion of roller bearing is assigned at axis and bearing between wheel shaft 25 and chassis 5 via bearing 30.

It can be seen that the part comprising the first material and/or layer 27 are attached on the core made of the second material, thus one Aspect realizes various performances and on the other hand ensures that the amount of friction between roller bearing 20 and spin 15 (Fig. 3) is as small as possible.

Roller bearing 20 in the embodiment of Fig. 2 a has hourglass shape, wherein the straight circular cone 23 of a butt and second section The straight circular cone 23 of head disposes on the contrary at the small diameter of the straight circular cone of butt.It can be equipped in the joint place of the two cones Spacer, the spacer can have tubular and/or polygon or analogous shape.Outer diameter D and internal diameter d are sized such that can be with Realize preferred angle [alpha].Angle [alpha] is the angle between wheel shaft 25 and surface 22.

Surface 22 can be attached to core 23.The component 23 and 22 can be attached to wheel shaft 25 in rotary manner.In the reality It applies in mode, core 23 is fixed at least one ball bearing 30 to realize smaller friction when roller bearing 20 rotates.

Fig. 2 b is concentrated in the angle on surface 22 of roller bearing 20.The wheel shaft 25 (Fig. 2 a) and roller bearing of angle [alpha] expression roller bearing 20 Angle between 20 surface 22.The angle, which can be assumed into, allows spin 15 to be guided by roller bearing 20, thus by as small as possible Friction so that skating equipment 1 be readily able to using.

Angle beta can be set to prevent spin 15 due to the badly damaged or lateral control of user from rolling The desired location of axis 20 is detached from.

Fig. 3 shows skating equipment 1 and generally comprises at least one spin 15 and chassis 5.
