    535 615 2 Ang P.ans nr 1 100288-8 For locking the wheel 1 to its wheel axle 2 there is a locking wheel 6. This locking wheel 6 has on its one side a cylindrical hub plug 7 fitting in the hub sleeve 3, which with easy sliding fit can be inserted into the open outer end 8 of the hub sleeve 3 and is rotatable in this hub sleeve 3.
    Through the hub plug 7 and the locking wheel 8 a second hole 9 for the wheel axle 2 is occupied.
    This second hole 9 is as much eccentrically offset a distance e2 (fi g. 3 and fi g. 4 - dotted lines) in relation to the center of the hub plug 7 as the hub sleeve 3 is eccentrically offset a distance e (fi g. 3 and fi g. 4 - solid lines ), relative to the first central hole 4 of the wheel axle 2 on the wheel 1.
    Hereby the wheel 1 can be locked on the wheel axle 2 by means of the locking wheel 6 after the locking wheel 6 is threaded on the free end of the wheel axle 2 and insertion of the hub plug 7 of the locking wheel 6 into the hub sleeve 3 on the wheel 1 and on the wheel axle 2 1 and the second hole 9 for the wheel axle 2 in the hub plug 7 opposite each other. After an insertion of the wheel axle 2 through both of these holes 4 and 9 and after a rotation of the locking wheel 6 relative to the wheel 1, a locking occurs.
    To release the lock between the wheel 1 and the wheel axle 2, the locking wheel 6 only needs to be turned in the opposite direction compared to when the lock was established. Then the locking wheel 6 and the wheel 1 can be easily pulled by the wheel axle 2.
    In the i fi g. In the sketch of the device according to the invention shown in Fig. 1, the wheel 1 is shown in perspective with the open outer end 8 of the hub sleeve 3 clearly visible. The locking wheel 6 is shown offset by about 90 degrees compared to the viewing direction of the wheel 1.
    The wheel axle 2 has been shown inserted into the wheel 1 and is shown Dashed between the wheel 1 and the locking wheel 6 to show the interaction between the hub sleeve 3 and the hub plug 7.
    I fi g. 3 shows a circle corresponding to the hub sleeve 3 and how this is eccentrically displaced a distance e 1 in relation to the first central hole 4 in the wheel 1.
    The circle also corresponds to the hub plug 7 and it is shown how this is eccentrically displaced a distance e; in relation to the second hole 9 for the wheel axle 2.
    Within the same type of circle used in fi g. 3 is shown in fi g. 4 with solid lines the position of the hub sleeve 3, and with dashed lines the position of the hub plug 7 after rotation of the locking wheel 6 is shown clockwise relative to the wheel 1 for locking.
    The rotation is shown to be greatly exaggerated for illustrative purposes. To clearly show the rotation, the position of the hub sleeve 3 has been shown with solid coordinate axes and the position of the hub plug 7 with dashed coordinate axes. 535 615 3 Ang P. ans no. 1100288-8 By using an elastically resilient material in at least one of the parts hub plug / hub sleeve, it becomes possible to arrange distinct locking positions between hub plug and hub sleeve. This resilience of the materials can be combined with specially designed cooperating cam surfaces in the hub plug and hub sleeve. In addition to the eccentricity in relation to the common shaft, these cam surfaces can, under the resilience of the materials, assume secure mutual locking positions, ie a certain minimum torque is needed to turn the parts back to an open position.
    The invention is not limited to the exemplary embodiment shown in the drawings, but modifications may be made within the scope of the following claims.
    权利要求:
    Claims (3)
    [1]
    Locking mechanism for releasable locking between two mutually rotatable, perforated elements (1, 6) on a common shaft (2) extending through said holes (4, 9), characterized in that one element (1) has a sleeve or hub sleeve ( 3) and the second element (6) has a pin or hub plug (7) fitting in the hub sleeve (3), the hub sleeve (3) and the hub plug (7) being arranged eccentrically with respect to the common shaft (2) in such a way that a relative rotation between the two elements (1, 6) causes them to be locked on the common shaft (2).
    [2]
    Locking mechanism according to claim 1, characterized in that at least one of the hub sleeve / hub plug (3, 7) consists of an elastically resilient material.
    [3]
    Locking mechanism according to Claim 1 or 2, characterized in that the common shaft (2) forms part of a cleaning tool.
