Securing device for a counter-balancing device for a door leaf.

摘要

Securing design for one or more counterbalancing torsion springs (1) of a door leaf, having holding bodies (2) which are provided for the spring ends (8) and at least one of which is so designed for connection to a holding block (3) that securing, maintained without screwing preferably only under spring force, takes place in that there is provided on the collar region (19) of the holding body (2) facing away from the connected spring end (8) a T-shaped shaped-out connection piece (14) which engages into a recess (13) of the holding block (3) in the manner of a bayonet fastening. At the same time, preferably the securing of the helix end region (30) of the connected spring (1) in the region of the collar (19) is maintained only under spring force as a result of hook-shaped engagement acting in the circumferential direction.
