    The invention relates to a windlass for shutters, blinds and the like. According to the preamble of claim 1.
    DE 23 47 582 A1 and the product data sheet from Gerhard Geiger GmbH & Co. KG entitled "GEIGER bevel gear for the roller shutter " is under the number 100W0308 de 0511 a windlass according to the preamble of claim 1, in which the coupling ring is provided with coupling elements, at the end faces inclined surfaces are provided. These inclined surfaces are directed so that the edge of the Getriebekörperausnehmung or claw deflects the coupling element against the spring force in one Windendrehrichtung and thus eliminates the frictional connection between the gear body and head, while the coupling element provides in the other Windendrehrichtung for a frictional connection between the gear body and head. This can be avoided in the unwinding of the pad from the winding hollow shaft and reaching the lower pad end, a winding of the pad in the wrong winding direction.
    Now, if a mounting or repair of a windlass required, the installer often does not know whether the customer has or wants a version for a left-hand drive or for a right-hand transmission. The fitter will therefore have to carry both types of windlass with him. This is very complicated. The cited prior art is not intended for conversion from left to right.
    It is an object of the invention to provide a windlass according to the preamble of claim 1, wherein the adjustment of the overrunning clutch to the left or right position of the transmission is possible by simply switching.
    This object is solved by the features of claim 1.
    The invention is realized in any case, if it is a windlass for shutters, blinds and the like. With a manually operated transmission, a rotating through this hollow shaft hollow shaft and with a coiled with the winding hollow shaft overrunning clutch. The overrunning clutch may consist of a cylindrical gear body, a cylindrical head and an acting between the gear body and head axially displaceable coupling ring. The gear body and the head are mounted on a fastened to the side wall of a crankcase cylinder socket. The head can be frictionally connected via a cap with the winding hollow shaft. The gear body and the head may have on their facing end faces a plurality of rectangular, on the gear body end face jaws forming recesses, between which act essentially quadrangular elements of the coupling ring against the spring force of at least one spring mounted in the head. The coupling ring elements in a Windendrehrichtung couple the gear body and the head with each other. In the other wind direction they are deflected axially. This repeals the frictional connection between the gear body and the head.
    The coupling ring element is designed according to the invention is substantially edged. A collar is provided with at least one oblique or rising side surfaces corresponding adjusting ring element between the coupling ring and gear body. The length of the gear body recess is preferably matched to the coupling ring element and the adjusting ring element in the Getriebekörperausnehmung so that they fit into the Getriebekörperausnehmung.
    The adjusting ring element can now be moved in the deflected state of the coupling ring elements from one edge to the other edge of a Getriebekörperausnehmung.
    Advantageous embodiment of the windlass can be found in the dependent claims. Thus, it is provided that the overrunning clutch consists of a cylindrical gear body (7), a cylindrical head (22) and between the gear body (7) and head (22) acting axially displaceable coupling ring (16), and that the gear body (7) and the head (22) are mounted on the attachable to the side wall of a crankcase cylinder socket (4) and that the head (22) via a cap with the winding hollow shaft is non-positively connectable and the transmission body (7) and the head (22) their mutually facing end faces a plurality of rectangular, on the gear body end face jaws (9) forming recesses (8, 26) between which substantially quadrangular elements (17) of the coupling ring (16) against the spring force at least one in the head (22) mounted Spring (20, 21) act.
    According to a further embodiment of the invention, four recesses in the gear body end face and the head end face are formed in each case. As a result, a better load distribution is achieved, with more or fewer recesses are possible.
    According to a further embodiment of the invention, the adjusting ring is provided with four equally distributed on the circumference adjusting ring elements, so that a tolerable "rockers". the winding hollow shaft is possible.
    According to a further advantageous embodiment of the invention, the adjusting ring is mounted on an annular shoulder formed on the gear body end face.
    According to a further advantageous embodiment of the invention, the adjusting ring element is provided with a rough outer surface or a rough recess. Thus, the collar is more handy to use.
    According to a further advantageous embodiment of the invention, the adjusting ring element is axially and radially connected to the gear body in the operating position. Thus, an accidental switching can be avoided by the coupling ring.
    The invention will now be explained in more detail with reference to an embodiment. Show it:

    Fig. 4c is a perspective view of the coupling ring of Figures 4a and 4b and
    Figures 5a to 5c are side views of the overrunning clutch of Fig. 1 with different actuating states of the adjusting ring.
    The exploded view of the windlass in Fig. 1 shows a plate 1 with mounting holes 2, with which the windlass can be attached to a side wall of a roller shutter box or the like, not shown fastened. The plate 1 is fixedly connected to a gear box 3 and a cylinder socket 4. In the gearbox 3 performs a connected to a not shown pinion hollow shaft 5, in the opening 6, a hand crank, not shown, is non-positively insertable. The pinion engages in a ring gear, not shown, arranged at the lower end of a cylindrical gear body 7, so that the mounted on the cylinder neck 4 gear body 7 can be rotated.
    The upper end face of the gear body 7 is provided with four evenly distributed on the circumference recesses, such as the recess 8. As a result, claws, such as the claw 9, are formed. Furthermore, this end face has a ring neck 10 surrounding the cylinder neck 4. The gear body 7 is shown enlarged in Figures 2a to 2c.
    On the ring shoulder 10, a collar 11 is placed. The adjusting ring 11 is shown enlarged in Figures 3a to 3c. It is provided with four uniformly distributed on the circumference, outwardly projecting control elements, such as the actuator 12, hen. The actuator 12 has two sloping or rising side surfaces 13, 14 and a corrugated outer surface 15.
    After the attached adjusting ring 11 is a coupling ring 16 rotatably supported on the cylinder neck 4. This coupling ring is shown enlarged in Figures 4a to 4c. The coupling ring 16 has four uniformly distributed on the circumference coupling elements, such as the coupling element 17, on. The coupling element 17 is substantially square with a here exemplified lower tapered portion 18 which is slightly chamfered at its outer edges. Each coupling element 17 is provided with a guided in the axial direction blind bore, such as the blind bore 19, as a spring support.
    In this blind holes, one or more helical compression springs 20, 21 engage opposite to FIG. 1. The choice of spring strength can be freely selected or changed according to the customer's request in terms of ease of the overrunning clutch.
    Further, a rotatably mounted on the cylinder neck 4, cylindrical head 22 is shown in Fig. 1, which is secured by means of washers 23 and an O-spring ring 24 which engages in an annular groove 25 of the cylinder nozzle 4, on this cylinder neck. The head 22 is provided with four circumferentially uniformly distributed rectangular recesses, such as the recess 26. In the recess 26, the coupling element 17 of the coupling ring 16 matches. The width of a coupling element 17 corresponds approximately to the width of a Kopfausnehmung 26. In the adjoining the recesses 26 parts of the coupling ring 16 not shown blind holes are provided, in which the upper ends of the Helical compression springs 20, 21 are insertable.
    The length of the recesses in the gear body is dimensioned such that the coupling ring member 17 and the adjusting ring member 12 fit into the Getriebekörperausnehmung 8 side by side.
    In the figures 5a to 5c three phases of the overrunning clutch from right to left operation are shown. In Fig. 5a, the adjusting ring member 12 is located to the left of the coupling ring member 17; the helical compression springs 20, 21 are relaxed. The fitter now turns the head 22 from the top to the right until the position shown in Fig. 5b of the coupling ring member 17 is reached. Now he can move the adjusting ring member 12 to the other stop in the Getriebekörperausnehmung 8 and turn back the head 22, so that the state shown in Fig. 5c is reached, in which the adjusting ring member 12 is located to the right of the coupling ring member 17. Thus, the switch from right to left operation is completed.
    The advantages of the windlass according to the invention are that the proven Geiger system is still used that the freewheeling torque is defined as usual on the helical compression springs, that little effort is required change that only one part, namely the collar, is additionally necessary and that no disassembly of other parts is necessary.
