Description

Motion assembly Technical Field The invention relates to a movement assembly, in particular for drawers, sliding doors, sliding windows or similar movable sliding elements (in particular furniture parts), comprising a retraction device, wherein the retraction device has a housing, which is provided with a damper, which comprises a cylinder and a piston guided therein, wherein an actuator (in particular a piston rod) is connected to the piston, such that the cylinder and the actuator are respectively provided with a trigger, indirectly or directly, wherein the trigger can be adjusted from a blocking position to a parking position in order to lock an actuator provided to the trigger in the blocking position and to release the actuator in the release position. Background Such a movement assembly is known from EP 2 247,812 B1. The motion assembly described in this document has two triggers. Wherein one trigger is pivotally secured to the piston rod of the damper and the other trigger is pivotally secured to the cylinder. The cylinder is guided laterally on bearings, and can thus be adjusted in the housing of the movement assembly. In order to be able to achieve a longer damping path, a relatively longer piston rod is used. In an alternative variant, EP 2 247,812 B1 describes a movement assembly in which the damper has a cylinder in which the two pistons are guided adjustably. Each piston carries a piston rod leading out of the cylinder on opposite sides. In the moving assemblies known from the prior art, the service life of the damper is limited, in particular when the moving assembly is subjected to a pulsed load frequently. Disclosure of Invention The object of the present invention is to provide a movement assembly of the type mentioned at the outset which is distinguished by a reliable and high-load-bearing construction. This object is achieved in that the actuator and the cylinder are guided independently of the trigger by means of the guide element. Since the actuator and the cylinder are guided independently of the two triggers, the force input via the triggers can be reliably received and output to the damper. This functional separation of the guides enables reliable load transfer even under strong impact loads. According to a variant of the invention, it can be provided that the housing is provided with a damper guide device which holds the damper adjustably on the housing. The damper is thus simultaneously mounted on the housing together with the support and guided there. The damper is thereby stabilized on the housing during the adjusting movement of the damper such that the damper is not displaced transversely to the load direction (in particular transversely to the longitudinal extension of the cylinder and thus transversely to the longitudinal extension of the piston rod) under sudden loads. It is thereby avoided that under such stresses the piston in the cylinder is tilted, i.e. skewed, transversely to the adjustment direction. Such an inclined position may lead to increased wear and thus to a lack of sealing in the area of the piston. The invention thus achieves a durable and reliable function of the damper, that is to say, whichever of the two triggers is pressurized during the adjustment of the damper. According to a variant of the invention, the support limits the freedom of adjustment of the damper, preferably the linear movement of the damper. The linear movement can extend in the direction of the adjustment direction of the actuator or parallel to this direction. According to a variant of the invention, the damper guiding device may have a holding section which holds the damper on the housing in a non-lost manner perpendicular to the longitudinal extension of the cylinder, and which enables guiding for adjusting the damper, preferably in the direction of the longitudinal extension of the damper, in particular in the direction of the longitudinal extension of the piston rod. In particular, in this case, the damper guide arrangement may prevent adjustment in a plane extending transversely to the longitudinal direction of the cylinder. By supporting the damper on opposite sides by means of the holding sections, a good guidance of the damper on the housing and at the same time a stable fastening of the damper can be achieved, wherein, for example, a three-point support can also be achieved. If a damper guide device is provided, in which the outer wall of the cylinder has a guide surface, in which the guide surface is guided, to adjustably hold the damper on the housing at its cylinder, guiding of the damper and at the same time supporting of the damper is particularly simple. Preferably, the guide surface is designed in a cylindrical shape so that the damper can be easily installed. A preferred inventive variant may be that the damper guide arrangement has at least one abutment, the cylinder of the damper being opposite the abutment on one side and on the side of the cylinder facing away from
