It must be ensured that the door automatically closes again at a small opening angle of, for example, 0 ° to 15 °, when the user releases it, stops at a mean opening angle of for example 15 ° to 50 ° in the respective angular position and only at large opening angles of, for example, 50 ° to 90 ° completely and gently falls into the open position. Since the weight of such a door can amount to several kilograms, high demands are placed on their training for a reliable continuous use of such spring units. They must also be mounted with a relatively high bias, which makes installation difficult. Such a spring unit is also referred to as a door weight balance spring system.
