    The friction brake is a special feature made on the pet leash that can be used to brake the unwinding of the strap. The brake function can be activated by pressing the thumb button. Once the function is activated, there is no need to press the thumb button and the brake remains active until the belt is no longer pulled out, but the return spring begins to rewind the tape onto the spool. Rewinding brings the friction brake back to its basic position. The friction brake eliminates the sudden stop of the pet, causing the walker and not the pet to squeak or jerk.

    Functional description Figure 1 The leash has a tape reel (2.) from which the tape (6.) is unwound by pulling out the tape. In this case, the spring (2b.) Inside the tape reel (2.) is tightened. With the force of the spring (2b.) The strip (6.) returns to the spool (2.). The strip (6.) runs between the pins (5.) of the track brake (4.). The gear brake (4) has a groove (1a) toothed on one side of the frame (1) against which the gear brake teeth (4a) are positioned. The belt (6) makes a bend at the pin (5) of the gear brake (4), whereby the force of the return spring (2a.) Of the spool holds the gear brake (4) in place. In this case, the track brake (4.) is in the home position and no braking takes place. The thumb button (3.) has a pusher (3a.) For pushing the gear brake (4.). When the thumb button (3.) is not pressed, the pusher (3a.) Does not affect the sprocket brake (4.). Fig. 2 Procedure for braking when the belt (6.) is pulled out: Pressing the thumb button (3.) causes the pusher (3a.) To move the sprocket brake (4.) in the toothed groove (1a.). The gear brake teeth (4a.) Allow the gear brake (4.) to move in the toothed groove (1a.) Only by rotation. The rotation of the sprocket brake (4.) starts to wrap the belt (6.) slightly around the pins (5.). In this case, the belt (6.) rubs against the two pins (5.) and the friction increases so much that the gear brake (4.) can rotate to its extreme position. Figure 3 In the extreme position, the belt (6.) rotates around the pins (5.) so that the belt is partially pressed against itself. The braking force can be adjusted by influencing how much compression occurs. This can be influenced by adjusting the point where the sprocket brake (4.) stops in the extreme position and by adjusting the height of the mouth opening (1b.) From which the belt comes out. At this point, it is no longer necessary to press the thumb button (3.) but the mechanism must be held in place until the belt (6.) is lowered and the spool return spring (2a.) Starts rewinding the belt (6.) back onto the spool (2.). The same force caused by the return spring (2a.) Acts through the belt (6.) on the gear brake (4.) which rotates back to the home position.

    Claims (4)
    [1]
    Coupling comprising a body (1), a handle (1C), a spool (2) with straps (6) and a thumb button (3), characterized in that the strap (6) runs between 5 pins (5) in a wheel brake (4) which is placed in a latch (1a) which is toothed on one side, where the wheel brake (4) can rotate in a limited area and a slider (3A) which acts on the wheel brake (4).
    [2]
    Method according to claim 1, characterized in that braking force arises from friction when the belt (6) moves around the pins (5), the belt (6) pressing against itself and from braking force control with which it is limited how much the belt (6) presses against himself.
    [3]
    Method according to claims 1 and 2, characterized in that as a result of the pusher (3A) being pushed forward, which pusher can be arranged on the thumb button (3), the wheel brake (4) is moved by rotation forward in the latch (1A) which is toothed on one side, causing the belt (6) to rotate around the pins (5) of the wheel brake (4) and causing braking of the belt (6), as a result of which the wheel brake (4) rotates to its extreme position, the belt (6) which goes around the pins (5) in the wheel brake (4) presses against itself and begins to brake the unwinding of the belt (6) without the pusher (3A) having to be pushed forward.
    [4]
    Method according to claims 1 and 2, characterized in that the wheel brake (4) returns to the home point by means of spring force (2A) of the spool (2) of the belt (6), when the spooled belt (6) becomes looser and the wheel brake (4 ) does not prevent the belt (6) from being rewound.
