Description

The invention relates to a device for Attaching and detaching rollers on single-track roller skates, at which the roller axes through aligned openings of a frame and in the openings are stored.

Such a device for attaching and detaching Rolling in single-track roller skates is for example from the US 5 088 748 A or US 5 183 275 A known. The Roller axes through aligned openings of one Frame inserted and stored in the openings, the Roller axes with the help of releasable locking members on Frame to be attached. Are as releasable locking members Screw nuts provided on the respective bolt end be screwed on. In the case of US 5,088,748 two nuts each for securing to the free end of the bolt screwed on, in the case of US Pat. No. 5,183,275 there is a fixation with to a mother, and in both cases the bolt lies with a bolt head provided on its other bolt end on the frame.

For the exact storage of rolls in a frame, which with connected to the shoe, or integrally formed with the shoe can be bearings in the openings of the frame can be used, such as those described in US Pat. No. 4,909,523 have become known. This US 4 909 523 A is also an education the bearing piece can be seen, which two different Elevation of the roller axes enables; however for one such training requirement that the breakthroughs in Frame deviate from the circular shape so that the bearing pieces in two different positions in the openings can be inserted.

AT 153 259 B is a single-track roller skate with one spring-loaded roller frame is known, with bolts as roller axles can be used with a bolt head attached to the frame stuck through the frame and the respective role and at the free End instead of a nut attachment using a general only shown releasable locking member are secured.

US 988 533 A also discloses a roller skate with a Device for attaching and detaching the rollers, in which the Roller axes with heads in recesses open at the bottom Frames are inserted and stored; in the heads of the roller axes are non-circular, e.g. square circumferential grooves provided with which the roller axes in the Ausnebmungen the yoke-like frame ends are inserted, then with With the help of detachable locking members in Form of tabs, which are hinged to the frame, are fixed. These tabs must be fixed to the yoke by stud screws will.

The known devices for attaching and detaching the Rollers therefore use tools such as wrenches or Allen keys, ahead, and therefore it's a carry certain tools for the exchange of roles. Furthermore, the individual parts, and especially the fasteners, such as nuts, not against Loss secured, and therefore they can be lost.

From GB 668 710 A is a device for fastening and Knocking out a wheel axle at driving edges is known. Here is that passed through an opening in a hub approach Screwed to the end of the axle with a U-shaped bracket part axially displaceable within a hollow cylindrical head part is arranged. Between the legs of the bracket part is a Eccentric clamping lever on one in the legs across the wheel axis attached bolt pivotally mounted; this eccentric clamping lever enables pressure transmission in the locked position over one below its eccentric area Block on the headboard, which in turn is on the support frame supports; at the same time, a pull on the Axis exercised on the other end of not explained in more detail Way is held.

In FR 2 536 290 A there is a two-track roller skate described, the frame of two telescopically telescopic Frame parts exist to adapt to different Allow shoe sizes; to fix the two Frame parts are provided by toothed racks a bolt pivotally mounted tensioning lever with eccentric Area can be engaged and released again.

The invention aims to be a particularly simple one Device for attaching and detaching the rollers in single-track To create roller skates, which are for the safe Definition of axes and roles required components in can be easily secured against loss and a particularly quick replacement or assembly without the aid of a user of tools is possible.

The invention provides a solution to this problem Device for attaching and detaching rollers in single-track Roller skates with the features of claim 1. As a result of that the axis has a circumferential groove or a free end Has opening, can be pivoted or over a flexible tension member fixed locking member, such as a locking bolt or a swiveling hook, with the circumferential groove or the opening of the roller axes in Be brought into engagement, whereby the roller axis against axial Movements in the pull-out direction can be secured. By the one at the other end of the roller axis transverse to the roller axis the respective roller axis can be pivoted be set, with a simple pivoting this Clamping lever exerts an axial pull on the roller axle and immediately a tension of the roller axis against the releasable Locking member results. So overall, by simply flipping the tensioning lever securely take place, the solution of the roller axis and thus the roles can be done in that the clamping lever is released, whereby the locking pin or the releasable locking member without effort disengaged and the roller axis removed can be. This results in a particularly quick and without With the help of tools removable roller axis, in which all Parts that are required for locking against loss are secured. A quick exchange of roles, in particular to achieve different running properties, is on this way possible.

The training is particularly simple met that the releasable locking member than by one to Roller axis essentially parallel axis pivotable hook is formed, which in the locking position in the Circumferential groove of the roller axis engages. Such training leads to a side-lying and against loss secured locking member, which due to the extremely Small dimensions are not easy even in tough use destroyed or not without simultaneous loosening of the tensioning lever can be disengaged again.

Alternatively, instead of such a swiveling hook a locking pin or cotter pin are used, whereby here of course, the loss protection via a flexible fastener should take place, which in turn has the consequence that the rough use of such fasteners can be destroyed can, the loss protection in the exchange phase would be lost from roles.

With the device according to the invention can also in a height-adjustable fixing in a particularly simple manner individual rollers and thus an exact adjustment of the altitude achieve. It is advantageously provided that the Roller axis height and with a bearing part relative to the frame can be set in a side-adjustable manner.

2 shows a view in the direction of arrow II of FIG. 1;

3 shows a view in the direction of arrow III of FIG. 1; and

4 shows a detail of the design of the roller bearing in accordance with the section according to FIG.

In Fig. 1, an axis 1 is shown, which openings 2 interspersed in a frame. Axis 1 points to a free one End of a circumferential groove 3 in which a hook-shaped locking member 4, as clearly shown in Fig. 2 is engaged by pivoting about the axis 5 and the axis 1 thus prevents pulling out in the direction of arrow 6.

The circumferential groove is formed in a particularly simple manner by that the free end of axis 1 is a blind hole 7, which is equipped with a thread in which a screw 8 is screwed in, between the Front of the axis 1 and the head of the screw 8, the circumferential groove remains in which the pivoting locking lever or hook 4 engages.

The end opposite the end defined by the hook 4 End of the axis 1 has a tension lever 9, which by a Axis 10 is pivotable. In the closed position shown an eccentric cam 11 is supported on the outside of the bearing component 12, whereby axis 1 in the direction of arrow 6 put under tension and between the two bearing parts 12, which are inserted into the openings in the frame, clamped becomes. The bearing parts 12 mentioned are eccentric formed so that by rotating these bearing parts 12 the Axis 1 in its height in the direction of the double arrow 13 is adjustable, with the locking member, of course is formed by the hook 4, relative to the axis 5 also must follow the position of axis 1 in the vertical direction.

On the axis 1 are 14 roles with the interposition of bearings 15 rotatably mounted.

2, as already mentioned above, is the hook-shaped locking member 4 shown in side view. Alternatively Such a hook-shaped locking member can in particular then when using eccentric inserts find, a locking pin can be provided here, which the axis 1 enforced. To make sure that in the locked position, in which the clamping lever 9 is pressed into its closed position the side walls of the frame will not be with the rollers collide, are spacers 16, as can be seen in FIG. 1, intended.

As can be seen from Fig. 3, the clamping lever 9 can be in any Swivel rotational positions, with a non-rotatable connection with eccentric bearing parts 12 depending on the selected rotational position a certain eccentricity in the dimension e, as they are results from the representation in Fig. 1 can be achieved. Of the Tensioning lever 9 is corresponding to the side view in FIG. 3 represented by arrow III.

4 are instead of the spacers 16 directly in one piece with the side cheeks 17 of the frame molded spacer elements 18 are provided. The remaining reference numbers correspond to the reference numerals in FIG. 1.
