Title:
METHOD FOR THE PRODUCTION OF CONNECTION SYSTEMS, AND CONNECTION SYSTEMS PRODUCED ACCORDING TO SAID METHOD
Document Type and Number:
WIPO Patent Application WO2004096518
Kind Code:
A3
Abstract:
Disclosed is a novel method for producing connection systems consisting of at least two plastic parts which are functionally movable relative to each other in a rotating manner. According to said method, the inner (1; 15) of the two parts (1, 2; 15, 16) that are rotationally movable relative to each other is first cast or injected from a plastic material in a mold, whereupon the outer (2;16) of the two parts (1, 2; 15, 16) that are rotationally movable relative to each other is cast or injected from a different plastic material over the inner part (1; 15). The inner part (1; 15) or at least one portion thereof is used as a core for the outer part, the two materials which are used for the inner and the outer part not being adhesive or sticking to each other. Such a connection system is provided with a pin part (2) comprising a pin (11), and an anchor part (1) comprising claws (5) that are forced apart by twisting the pin (11), for example. The pin part (2) is used as a core for the anchor part (1) during the production process.
