Definitions

  • the present invention relates to a locking device for movable furniture parts, with a guide rail with a large number of blocking elements, which is held so that it can be displaced along the guide rail, each blocking element having a starting bevel which can be contacted by an activator attached to a movable furniture part, and each blocking element has one Has a wall that can form a stop for the activator in order to lock the movable furniture part with the activator in a closed position, the guide rail with the locking element between an anti-tilt position in which all activators are arranged adjacent to a starting bevel on different locking elements, and a blocking position in which all activators arranged in the closed position are arranged adjacent to a wall on different blocking elements, can be moved, and a method for locking at least one movable furniture part on a furniture body with a lock owing device.
  • U1 discloses a locking system for pull-out furniture parts, in which a locking bar with a large number of sliding parts is provided.
  • a movable furniture part acts on a driver which is in engagement with one of the sliding parts in order to move the sliding parts from an unlocked position into a locked position.
  • the driver is slidably mounted on a housing and can be coupled to a movable piece of furniture over a short distance. The interposition of such a driver between the movable furniture part and the locking strip means increased manufacturing and assembly costs.
  • DE 10 2005 054 006 B4 discloses a pull-out protection for pull-out furniture elements, in which a large number of locking elements can be displaced along a linear guide.
  • the locking members can be moved by a bolt that is attached to a movable furniture element.
  • the bar is designed in the form of a strip and extends almost over the entire length of the furniture element.
  • the structural complexity is disadvantageous due to the great length.
  • the pointed ends of the bars can easily be damaged.
  • each blocking element has a starting bevel which can be contacted by an activator attached to a movable furniture part.
  • Each blocking element also has a wall that can form a stop for the activator in order to lock the movable furniture part with the activator in a closed position.
  • the guide rail with the blocking elements can be moved between an anti-tilt position, in which all activators are arranged adjacent to a starting bevel on various blocking elements, and a blocking position, in which all activators arranged in the closed position are arranged adjacent to a wall of various blocking elements.
  • the guide rail In the anti-tilt position, the guide rail can be displaced into the blocked position, in particular in the longitudinal direction of the guide rail, and then held in the blocked position by a holding device when an activator moves against a contact slope.
  • a holding device In the anti-tilt position, the guide rail can be displaced into the blocked position, in particular in the longitudinal direction of the guide rail, and then held in the blocked position by a holding device when an activator moves against a contact slope.
  • the holding device holds the guide rail in this locked position until the furniture part in the open position is moved back into the closed position and the guide rail is unlocked by the holding device so that the guide rail is again arranged in the anti-tilt position.
  • the activator can be moved together with the movable furniture part, in particular the activator can also be fixed directly to the movable furniture part. This reduces the number of components required for the locking device and enables easy operation in which the activator can be made compact.
  • the holding device preferably holds the guide rail in the blocking position in a form-fitting and/or force-fitting manner, in particular in a clamping or latching manner.
  • This enables the guide rail to be easily fixed using clamping elements or latching elements such as latching webs, latching receptacles or latching projections.
  • the use of magnetic holding means is also possible here in order to create an almost wear-free holding device.
  • the guide rail can be moved from the blocking position to the anti-tilt position via an activator, which is moved from the open position in the closing direction with the movable furniture part, the activator then being movable along a guiding slope on a blocking element.
  • the blocking element can then release the guide rail from the blocking position via the guide bevel and then move it into an anti-tilt position.
  • the guide bevel can be arranged on the opposite side of a blocking element to the run-on slope, with the term “opposite” referring to the direction of movement of the activator, which is moved against the run-on slope during a movement on the movable furniture part in the opening direction and in the opposite direction Movement is moved in the closing direction against the guide slope.
  • the blocking elements are preferably biased into a raised position by an energy accumulator.
  • the activator can move at least some of the blocking elements against the force accumulator into a lowered position by means of an activator that can be moved along the guide slope.
  • the locking elements can be prestressed against an end stop on the guide rail via the force accumulator, so that the locking elements can be moved along the guide rail via the activator, regardless of whether the activator is moved against the starting slope or the guiding slope. As a result, at least part of the blocking elements can be displaced, which form a gap through which the activator can then be passed.
  • the energy store can automatically move the locking elements back to a closed position and close the gap created by the activator again.
  • the force accumulator can be supported on one side on a stop that is fixed to the guide rail and on the opposite side of one of the locking elements or on a component between the locking elements and the other end of the force accumulator.
  • the energy accumulator can be designed as a separate spiral, shaped or leaf spring or integrally as an elastic element on a stop of the guide rail.
  • a latching mechanism is preferably provided, by means of which the guide rail is fixed in a raised position. This leads to greater security during operation.
  • the latching mechanism can, for example, comprise a heart-shaped curve or a latching web, which ensures that the guide rail is secured in a raised locking position.
  • Each blocking element preferably comprises a channel-shaped receptacle through which an activator can be passed without displacing the blocking elements.
  • This channel-shaped receptacle can be used to move the locking device into a release position in which all activators are arranged adjacent to a channel-shaped receptacle, so that all movable furniture parts are also moved simultaneously in the opening direction.
  • This release position makes sense if the moveable furniture parts are to be removed for disassembly, for example during assembly, for cleaning or for a move.
  • a switching mechanism, in particular a lock, on the locking device can therefore have three positions, the release position in which all movable furniture parts can be moved in the opening direction, the anti-tilt position in which only one of the movable furniture parts can be moved in the opening direction at the same time, and a locking position , in which all movable furniture parts are locked in the closed position.
  • Each activator is preferably designed as a pin that can be fixed on the movable furniture part.
  • the pin can be fixed directly, for example, in a side wall or side frame of the movable furniture part.
  • the moveable furniture part and the activator can also be fixed to one another via holders or other components, for example via the pull-out guide.
  • a first movable furniture part is first moved from a closed position in an opening direction, with an activator held on the furniture part being moved against a run-up slope on a blocking element which is held on a guide rail, wherein the blocking element moves the guide rail from an anti-tilt position to a locking position in which all other movable furniture parts, except for the first furniture part, are locked in the closed position.
  • the guide rail is then held in the locking position by a holding device, with the blocking elements blocking a movement of at least one second furniture part, in particular all other furniture parts apart from the first furniture part, from the closed position in the opening direction.
  • the holding device can hold the guide rail in the locking position in a form-fitting and/or force-fitting manner, in particular in a clamping or latching manner.
  • the first furniture part is moved back into the closed position, with the activator on the first furniture part being moved against a guide slope on a locking element in order to release the guide rail from the locking position and move it into the anti-tilt position in which a movable furniture part can be moved in the opening direction.
  • the movement of the blocking elements via the activator is thus used to move the guide rail from an anti-tilt position to a locking position and hold it there, which makes it possible to move the activator in an opening area independently, in particular at a distance from the locking device. Only when the activator moves in the closing direction can the activator move the guide rail again from the closed position to the anti-tilt position via a blocking element shortly before the closed position.
  • the blocking elements When the activator moves on the first furniture part against the contact slope, at least part of the blocking elements is preferably displaced against an energy accumulator along the guide rail.
  • the blocking elements can thereby form a gap in order to guide the activator through two adjacent blocking elements.
  • This movement of the blocking elements against the force accumulator can allow a brief formation of a gap between two adjacent blocking elements for the activator to pass through.
  • the guide rail is simultaneously moved into a blocking position and can be held there in a latching or clamped manner until the activator is moved back into the closing direction.
  • the activator moves on the first furniture part against the guide slope, i.e.
