Embodiment Construction

[0033] Figure 1a A cross-sectional view of the sleeve 14 with a closed head 24 is shown and shows the coil spring 12 inserted into the sleeve 14 as indicated by the arrow 20 . The sleeve 14 is made of thermoplastic and the helical spring 12 is a metal spring.

[0034] Figure 1b The state in which the helical spring 12 has been inserted into the sleeve 14 is shown in a sectional view. Projecting from the peripheral wall, three ribs 11 are formed on the inner surface offset from one another by 120°, and these ribs accommodate fastening sections 13 of the helical spring 12 . The helical spring 12 is here inserted into the sleeve 14 with a sliding fit, wherein the various parts of the helical spring 12 abut or nearly abut on the region 16 of the sleeve, in particular on the ribs, close abutment means that it is only close to the sleeve. with small spacing. The helical spring 12 is inserted into the sleeve 14 so far that the helical spring does not bear against the tapered reg...

Abstract

The present invention relates to a spring sleeve (10) or a spring pin, consisting of a helical spring (12) made of metal, and at least one sleeve (14) fit on an end of the helical spring (12), said sleeve having a closed head (24), wherein the helical spring (12) protrudes from the sleeve (14), or at least one pin inserted at one end of the helical spring (12) with a head, wherein the head of the pin protrudes over the helical spring (12). The sleeve (14) or the pin consists of a thermoplastic plastic and the sleeve (14) or the pin is connected to the helical spring (12) by means of induction welding.

Description

technical field [0001] The invention relates to a spring sleeve or spring pin comprising a helical spring and at least one sleeve over one end of the helical spring, said sleeve having a closed head, Wherein the helical spring protrudes from the sleeve, or comprises a helical spring and at least one pin inserted at one end of the helical spring, the pin having a head protruding from the helical spring. Background technique [0002] To produce such spring sleeves, until now, helical springs have been inserted into sleeves made of metal. The sleeve is then deformed in a point-like manner such that the helical spring remains inside the sleeve. This is achieved, for example, by embossing, wherein embossing pins are pressed into the sleeve wall on one side of the sleeve, whereby the embossed wall projections are pressed between the turns of the helical spring and the helical spring is fixed in place. in the sleeve. In the case of spring pins, a helical spring is screwed or sli...
