US Patent 11384583 Retraction device for two end positions

A retraction device for two end positions has two driving elements which are connected to one another by a spring energy accumulator. Each driving element is displaceably mounted in a respective guide housing. A sliding door has such a retraction device, and a sliding door arrangement has such a sliding door. Each driving element is coupled or can be coupled to a cylinder-piston unit mounted in the respective guide housing. Both guide housings are adjustable relative to one another in the longitudinal direction of the retraction device by means of at least one sliding joint. This provides a retraction device for two end positions, which can be used for a range of door widths without design modifications.
