ASSEMBLY FOR ABSORPTION OF THE SHOCK CAUSED BY ONE-WAY BEARING ON THE ROLLER-SKI WHEEL

Abstract

The assembly for the amortization of the impact of the roller-ski wheel, caused by one-way bearing, generally relates to the field of sports training equipment. More closely, it relates to the field of skates, skis, and rollerblades, and specifically refers to the classic roller-ski. The assembly for absorption of the impact of the roller-ski wheel caused by one-way bearing (I) of the wheel (C) of the roller-ski (A), characterized by the axle (H) of the wheel (C) being rotationably inserted into the body of roller-ski (A), while two discs (G) are fixed on the axle (H) bilaterally and symmetrically relative to the wheel (C), with each disc (G) having the springs (E) bilaterally and symmetrically attached to it with its one end while being attached to the body of roller ski (A) by the bolt (J) with its other end.

The assembly for absorption of the impact of the roller-ski wheel caused by one-way bearing (I) of the wheel (C) of the roller-ski (A), characterized by the axle (H) of the wheel (C) being rotationably inserted into the body of roller-ski (A), while two discs (G) are fixed on the axle (H) bilaterally and symmetrically relative to the wheel (C), with each disc (G) having the springs (E) bilaterally and symmetrically attached to it with its one end while being attached to the body of roller ski (A) by the bolt (J) with its other end.

2. The invention according to the patent claim 1, characterized by the disc (G) being unilaterally fixed to the axle (H) of the wheel (C), with the axle (H) being rotationably inserted into the roller-ski body (A), while the spring (E) is unilaterally fixed to the disc (G) with its one end, while its other end is attached to the body of roller ski (A) by the bolt (J).

Description

BRIEF DESCRIPTION OF DRAWINGS

[0008] The invention is described in detail on the example of performing shown in the drawing in which:

[0009] FIG. 1 is a side view of a roller-ski with its back wheel and spring in a neutral and strained position.

[0010] FIG. 2 is a cross-sectional view of the invention from above.

BEST MODES FOR CARRYING OUT OF THE INVENTION

[0011] The presentation of the invention shown in FIGS. 1 and 2 shows the body of the roller-ski A in the direction of movement B. Into the roller-ski body A, a sliding insert has been put, through which a free rotation of the axle H of the wheel C is allowed inside the roller-ski body A. On such placed axle H of the wheel C into the roller-ski body A, on its both sides symmetrically, discs G are fixed, so that the turning of the axle H is transferred to the rotation of the discs G. On the discs G the springs E are attached by their one end, while their other ends are attached to the roller-ski body A over the bolts J. At the moment when the blockade of the one-way bearing I is activated, the wheel C, the axle H and the discs G turn backwards, because the axle H is rotationally incorporated into the roller-ski body A, but this provokes the straining of the springs E within their elasticity zone until they reach the fully strained position F, which all is a result of the straining force calculations. By straining the springs E, which with their strength and geometry, are progressively blocking the rotation of the wheel C in direction D, until they reach the fully strained position F, which is a progressive process from 0% to 100% of the force engaged, and all of this eliminates the impact of the blockade of turning the wheel C backwards.

[0012] FIG. 1 clearly shows the connection and position of the spring E and the axle H, as well as the freedom of rotation of the axle H inside the body of the roller-ski A, before and after activation of the blockade, showing the stopping of the rotation of the wheel C which is directly proportional to the elasticity of spring E and its geometry, which represents the element of regulation of the path length L until the final stop.

[0013] FIG. 2 shows a bilaterally symmetrical construction of the invention, while a one-sided construction is possible in which a disk G with a fixed connection to the axle H of the wheel C is placed on one side of the axle H of the wheel C so that the rotation of the axle H is transmitted to the rotation of disk G. On the disc G, the spring E is fixed to one end, while the other end is attached to the body of the roller-ski A over the bolt J.
