Apparatus for controlling the movement of a rail guide, rail guide, and furniture

Abstract

An apparatus for controlling the movement of a rail guide which comprises a fixed rail and a moving rail that is linearly displaceable in an opening direction and in a closing direction. The apparatus is designed for force-assisted displacement of the moving rail in the opening direction and has an energy accumulator, a main component and a carriage that is displaceable with respect to the main component. The carriage is movable in the opening direction under the effect of the loaded energy accumulator and, when the apparatus is mounted on the rail guide, carries along the moving rail in the opening direction. The apparatus has a locking arrangement with a cardioid and a locking body that can be brought into contact along the cardioid. When the energy accumulator is loaded, a displacement of the carriage in the opening direction is blocked. The carriage has the cardioid.

1 . An apparatus for controlling the movement of a rail guide which comprises a fixed rail, connectable to a furniture carcass, and a moving rail, couplable to a furniture part, wherein the moving rail is linearly movable in an opening direction and in a closing direction relative to the fixed rail, wherein the apparatus is designed, when arranged on the rail guide, for force-assisted movement of the moving rail out of a closed position of the moving rail in the opening direction, wherein the apparatus has an energy accumulator, a main component and a slide that is movable with respect to the main component, wherein the slide is movable in the opening direction under the effect of the loaded energy accumulator and, when the apparatus is mounted on the rail guide, takes the moving rail along in the opening direction, and wherein the apparatus has a locking arrangement with a cardioid and a locking member that can be brought into contact along the cardioid, so that, when the energy accumulator is loaded, movement of the slide in the opening direction is blocked in a locking position of the apparatus, wherein the slide is capable of being moved linearly backward and forward while being guided on the main component, wherein a synchronization device having a connecting element is provided, wherein the connecting element is designed to connect the apparatus to another, corresponding apparatus, wherein the two apparatuses are present in such a way as to be spaced apart, wherein the two apparatuses are designed, when connected, for controlling the movement of two rail guides for a shared furniture part, wherein the connecting element connects the two slides of the two apparatuses to one another in such a way that synchronized cancellation of the blocked position of the slide of one apparatus and of a slide of the other apparatus is enabled, wherein a linear movement of the slide and a rotary movement of the connecting element about its longitudinal axis take place in a mechanically coupled manner, and wherein the slide comprises the cardioid. 
     
     
         2 . The apparatus as claimed in  claim 1 , wherein the slide comprises a gear contour, wherein the gear contour is designed for the geared movement coupling of the linear movement of the slide and of a rotary movement of the connecting element about its longitudinal axis. 
     
     
         3 . The apparatus as claimed in  claim 1 , wherein, based on the apparatus being arranged on the rail guide, the cardioid is formed on an upper side of the slide. 
     
     
         4 . The apparatus as claimed in  claim 1 , wherein the cardioid and the locking member are matched to one another in such a way that the locking position of the apparatus can be canceled by a movement of the slide in the closing direction. 
     
     
         5 . The apparatus as claimed in  claim 2 , wherein the gear contour of the slide is designed as a toothed contour. 
     
     
         6 . The apparatus as claimed in  claim 2 , wherein the gear contour of the slide is present in such a way as to be adjacent to a receiving portion of the apparatus, wherein the receiving portion is designed to accommodate a gear element. 
     
     
         7 . The apparatus as claimed in  claim 2 , wherein the gear contour of the slide is linearly movable in a tangential direction with respect to an axis of rotation of the connecting element. 
     
     
         8 . The apparatus as claimed in  claim 6 , wherein the gear contour of the slide is in geared engagement with a mating gear contour formed on the gear element. 
     
     
         9 . The apparatus as claimed in  claim 6 , wherein the gear element is designed as a separate component, wherein the gear element is in geared connection with the slide. 
     
     
         10 . The apparatus as claimed in  claim 6 , wherein the gear element is configured for releasable attachment of an end portion of the connecting element. 
     
     
         11 . The apparatus as claimed in  claim 6 , wherein the receiving portion has a wall which is present circumferentially with respect to the axis of rotation of the gear element. 
     
     
         12 . A movement control system for two rail guides, which are used for joint guidance of the movement of a furniture part, wherein the movement control system comprises two apparatuses as claimed in  claim 1 . 
     
     
         13 . A rail guide having a fixed rail, connectable to a furniture carcass, and having a moving rail, couplable to a furniture part, wherein the rail guide comprises an apparatus as claimed in  claim 1 . 
     
     
         14 . An item of furniture having a furniture carcass and a movable furniture part, wherein the item of furniture comprises two rail guides as claimed in  claim 13 . 
     
     
         15 . An item of furniture having a furniture carcass and a movable furniture part, wherein the item of furniture comprises a movement control system as claimed in  claim 12 .
