Problems solved by technology

The disadvantage of this solution is that at the connection point the part with the rectangular dowel is first pressed into the anchor and then the anchor is pre-inserted into the connection hole before the final connection is established by turning the dowel

Embodiment Construction

[0030] figure 1 Shown is a first embodiment of a connection system manufactured in a manner to be described in more detail below. The system consists of an anchor 1 and a dowel 2 which together with the anchor 1 form a complete unit which looks like a unit and is handled like a unit when it is in use. From Figures 2 to 4 It can be clearly seen that the anchor 1 consists of a disc 3 with a central hole 4, from which two mutually opposite claws 5 protrude downwards and inwards, these two claws are in the The free ends each have an inwardly pointing shoulder 6 . On the upper side of the disk 3, two mutually opposite bosses 7 are integrally formed along the circumference, the respective ends of which form stops 8 . Such as Figures 5 to 7 As shown, the tenon member 2 is composed of a circular plate 9 from which two positioning pins 10 protrude radially from the side of the circular plate. From the center of the plate 9 projects a tenon 11 downwards. The bolt has a rectangul...

Abstract

Production of connection system out of at least two plastic components, where components can be rotated relative to each other, comprises initially molding inner part (1), followed by outer part (2). The inner part or a section of it, is used as core for outer part, and the two materials do not stick to each other. The connection has pin (11) and anchor with claws (5) that are forced apart by twisting pin. A process for producing a connection system out of at least two plastic components, where the components can be rotated relative to each other, comprises initially molding the inner part (1), followed by the outer part (2). The inner part or a section of it, is used as a core for the outer part, and the two materials do not stick to each other. The connection has a pin (11) and an anchor with claws (5) that are forced apart by twisting the pin. The pin is used as a core for the anchor during production. Pin rotation is limited to 90 degrees by stops. The anchor consists of a plate (3), and the claws extend from it.

Description

technical field [0001] The invention relates to a connection system having at least one inner plastic part and one outer plastic part, which are functionally movable relative to one another in rotation. Background technique [0002] However, in the case where parts are to be connected to each other, detachability and reconnection of the connection are often required without damaging the parts and without connecting tools. Up to now, connection systems consisting of at least two separate parts must be connected every time when the connection is established. Fit together and functionally engage together, then can be disassembled from each other again, and can be reused when re-establishing a connection or to make another identical connection, such as screws and nuts. [0003] The disadvantage of this connection system is that it can only be used for connection points that are accessible from both sides of the parts to be connected. The connection of the two parts of such a co...
