Embodiment Construction

[0089] figure 1 A schematic perspective view of a first spring assembly 2 according to an embodiment is shown.

[0090] The first spring assembly 2 comprises a first helical spring 4 whose inner space 8 is formed by its spring winding 6 . The first helical spring 4 in the figure stretches obliquely from the upper left corner to the lower right corner. The spring windings 6 are combined into a lower winding 10 at one end of the first helical spring 4 and into an upper winding 12 at the upper end. It is also possible to provide a plurality of upper and lower end windings 10 , 12 respectively, which then for example directly adjoin one another, thereby forming a particularly stable end of the first helical spring 4 , wherein the windings 10 , 12 adjoin. Between the end windings 10 and 12 , the spring windings 6 have a greater pitch, and adjacent spring windings 6 do not abut but form a space therein. In the region of the end windings 10 , 12 , the pitch of the first helical sp...

Abstract

The invention relates to a spring assembly (2, 34, 46), comprising: a coil spring (4, 36) having an interior space formed by the turns (6, 38) of the coil spring; and an anti-entanglement element (14,26, 48) for protecting the spring assembly (2, 34, 46) from entanglement, in particular from entanglement with at least one further spring assembly (2, 34, 46) or with at least one other coil spring(4, 36), the anti-entanglement element (14, 26, 48) being arranged at least partly in the interior space formed by the turns (6, 38) and extending through at least part of the interior space in the longitudinal direction, and the anti-entanglement element (14, 26) being formed as an anti-entanglement bow (14, 26), in particular an anti-entanglement wire bow separate from the coil spring (4, 36), which is retained in the interior space in a clamping manner; or the anti-entanglement element (48) being formed as an anti-entanglement pin (48), in particular an anti-entanglement plastic pin separate from the coil spring (4, 36), said pin having a front retaining end and a rear stop end.

Description

technical field [0001] The present invention relates to a spring assembly comprising a helical spring and an anti-wrap element extending within the coil spring windings. The invention also relates to a method for introducing an anti-wrap element into the inner space of a helical spring and a method for removing the anti-wrap element from the inner space of a helical spring. Background technique [0002] When coil springs are manufactured, usually a plurality of coil springs are dispensed into a common container, and the coil springs are transported to their destination in this container. This often causes problems with the coil springs wrapping and being difficult to separate from each other at the destination. Sometimes intertwined helical springs simply cannot be separated without damage. [0003] From DE 38 09 494 A1 it is known to manufacture helical springs which are loosely strung on steel wires and stored in a container as a "spring chain". During further processin...
