Embodiment Construction

[0031] 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

The invention provides a connection system consisting of at least an inner plastic part and an outer plastic part which are functionally rotatable relative to each other. The inner plastic part is an anchoring member(15) comprising a fin forming an elastic support at the lower side of a board and a column(20) protruding from the upper side; a cover (21) can rotate on the protruding column. According to the invention, the plastic parts are made of different plastic materials, wherein the inner part or at least one portion thereof is used as a core for the outer part, and the two materials are not adhesive or sticking to each other; the column(20) protruding from the anchoring member(15) has external thread; the cover(21) has a blind hole(23) with internal thread.

Description

[0001] This application is a divisional application with the application number 200480011648.X, the filing date is April 14, 2004, and the title of the invention is "the manufacturing method of the connection system and the connection system manufactured by this method". technical field [0002] The invention relates to a method for the manufacture of a connection system consisting of at least two plastic parts which are functionally capable of relative rotational movement, and to a connection for the detachable connection of the two parts produced in this way system. Background technique [0003] 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 ca...
