Definitions
- the invention relates to a ball coupling for lamellar according to the preamble of claim 1.
- the Cord represents the connection between the carrying cord and, depending on Embodiment of the slat blind, the turning device ago, the the slats over the carrying cords, depending on the desired direction, swings up and down, d. H. the store opens or closes.
- the cross section of the cord is usually round. Because the cord is exposed to high tensile loads, it is preferably made plaited several individual threads.
- the cord is by means of a Retaining element at its end with the ball coupling such connected, that the retaining element is under tensile load of Insert cord firmly in the ball coupling. This is done by a Rejuvenation ensured in the ball coupling. This rejuvenation is opposed by an extension through which the retaining element is introduced in the ball coupling.
- the retaining element may be in the form of a sphere or a sphere, for example oval or round and flattened, be formed. Is this Retaining a ball, then the ball as a ball cord designated.
- the carrying cord is because they too exposed to high tensile loads is also made of plaited monofilaments. In contrast The cord is not round, but flat. The Carrying cord is on the opposite end of the cord Ball coupling attached.
- Ball couplings in various embodiments are already known in the art (e.g., US-A-4,678,360).
- plastics which is the use requires injection molding, thereby reducing the production of Ball couplings is very expensive.
- a such ball coupling is the connection of the support cord with the coupling by a screw, which by means of a Allen key is moved.
- This embodiment has the Advantage that the lamellar curtain when the completion of the Carrying cord is long enough, can be adjusted in height.
- the carrying cord if the Screw is not tightened enough, from the ball coupling can slip out. If the screw is too strong attracted, the plastic can be blown up.
- Another Disadvantage is that a so-called cold flow occur can, whereby the clamping force is insufficient over time.
- the positioning of the plastic part proves to be very difficult on the carrying line, as the carrying line slips easily can until the screw is tightened.
- the invention is based on the object, a ball coupling create, in which the ball cord easily and safely mountable and is removable, and the carrying cord is not undesirable dissolves and is much cheaper to manufacture than the previously used hooks.
- a clutch with an overload protection discloses a connecting part comprising a mounting device with two elongated, mutually curved, a receiving space for a retaining element a cord forming, extending along the longitudinal direction of the coupling Has legs and a clamping means for a carrying cord.
- the resilient legs a receiving space for the retaining element.
- This reception room features at its curved, resilient legs opposite side an inside protruding Embossed on, providing an additional support for the retaining element the cord represents.
- the entry and exit of the Retaining element takes place in the space provided for him receiving space against the resistance of the coinage.
- the Ball coupling of the present invention one of two lobes existing clamping means for the carrying cord on which Fixing the carrying cord to be bent inwards.
- the hanging hook is the present invention made of sheet metal.
- Figure 1 shows a section through a ball coupling according to the present invention.
- the two shown in Figure 2) after inside bent resilient leg 4 of the mounting device. 2 form a receiving space 5 and hold the ball 8 of the ball cord 7 such that the ball 8 can not solve independently.
- the embossment 6 is opposite (see also FIG 4).
- the embossment 6 comprises a circular elevation in the interior of the Receiving space 5. This stamping 6 causes the ball 8 against the two resilient legs 4 is pressed and not undesirable can slide out of the mounting device 2.
- the ball 8 is against the resistance of the coin 6 from the receiving space in and out.
- the approximately flush course of the ball cord 7 with the Carrying cord 10 is ensured by the opening 9.
- the opening 9 is formed by two zueiander curved leg 11, the only so far bent that the ball cord axially aligned Can take position positions.
- the carrying cord 10 is by the two tabs 12 in position held by the tabs 12 after insertion of the carrying cord 10 in the connecting part, for example by means of a clamping pliers be compressed and thereby the carrying cord 10 in her Permanently fix the position.
- Figure 5 shows a section through a ball coupling in the area of the receiving space 5 for the ball cord 7. Shown are the two resilient legs 4 and surrounding the opening 9 Leg 11, over which the ball cord runs.

Description
- Die geometrische Ausbildung der federnden Schenkel der Haltevorrichtung und die im definierten Abstand angeordnete Rückhalte-Prägung ermöglicht eine sichere Verbindung und Lösbarkeit zwischen der Kugelkordel und der Tragschnur.
- Die Montage der Kugelkupplung an die Tragschnur kann durch eine einfache Klemmzange erfolgen, was die Verwendung eines Imbusschlüssels unnötig macht.
- Nach dem Positionieren der Kugelkupplung auf der Tragschnur wird mit einer Klemmzange eine dauerhafte Verbindung hergestellt. Ein Verrutschen der Tragschnur oder ein Lösen der Verbindung tritt bei der erfindungsgemässen Kugelkupplung nicht auf, da dessen Material und die Art der Befestigung der Tragschnur dies ausschliessen.
- Die Herstellung der erfindungsgemässen Kugelkupplung ist wesentlich kostengüstiger als diejenige der bereits bekannten Kupplungen, da sie durch einfaches Stanz-Biegen aus Blech hergestellt wird. Auf die Verwendung von mehreren Teilen, d.h. einem Spritzgussteil und einer Schraube kann verzichtet werden.
