Definitions

  • the invention relates to a device for closing a movable furniture part, in particular a drawer, door or flap, with a retraction device which has a first retraction unit with a first retraction element having an energy store and a second retraction unit with a second retraction unit, which is connected downstream of the first retraction unit in a closing direction of the movable furniture part Having force accumulator having second retraction element, the retraction elements each exerting a closing force closing direction of the movable furniture part when the movable furniture part is closed.
  • Such devices for closing a movable furniture part in the form of a drawer have been known for a long time.
  • the retraction unit supports the closing up to the fully closed position or takes over the closing automatically. In the latter case, handling of the drawer is no longer necessary once the automatic feed mechanism has been triggered.
  • This automatic retraction is made possible by an energy storage device integrated in the intake unit, which is charged when the drawer is opened.
  • the energy store can be, for example, a spring that is tensioned when the drawer is opened. The energy storage device is charged when the drawer is extended.
  • the feed unit After a certain extension path, the feed unit will be removed from the drawer decoupled, the energy storage device is charged, for example the spring is tensioned, the subsequent extension of the drawer taking place decoupled from the retraction unit.
  • the energy storage device When the drawer is opened, the energy storage device must first be charged, in particular the spring must be tensioned, which requires an opening force.
  • a locking device of the type mentioned is for example from the WO 2010/143352 A1 known.
  • There two draw-in units connected one behind the other in the closing direction are provided, which are arranged on a common base plate, which in turn is mounted on the inner wall of the furniture compartment receiving a drawer above the body rail.
  • the drawer On the side wall of the drawer there is a driver which, when it is closed, first triggers the front first retraction unit, which releases the spring force of a previously pre-tensioned spring.
  • the second draw-in unit is triggered by a component of the first draw-in unit that moves with it.
  • the two springs of the draw-in units are tensioned synchronously until the second rear draw-in unit is first decoupled and then the first draw-in unit is decoupled.
  • the object of the invention is to create a device for closing a movable furniture part of the type mentioned at the beginning, which is characterized by greater reliability and greater flexibility compared to the prior art mentioned above. This object is achieved with a device for closing a movable furniture part having the features of independent claim 1. Further developments of the invention are presented in the subclaims.
  • the feed units are separate, uniformly manageable assemblies, they are completely self-sufficient. For example, in the event of damage, one of the feed units can be replaced by another without the non-defective feed unit having to be dismantled in any way. Furthermore, the two feed unit assemblies, which can be handled separately from one another, offer a redundancy, which the aforementioned prior art does not offer. In the prior art mentioned above, in order to trigger the second rear draw-in unit, it is necessary that the first draw-in unit has triggered, since a component arranged on the first draw-out unit triggers the second draw-in unit.
  • the second pull-in unit does not trigger either.
  • the retraction units are designed in such a way that, when the movable furniture part is closed, they can each be triggered by a component belonging to the device and assigned to the movable furniture part are.
  • the component can, for example, be a driver or a latch.
  • the first intake unit has a first intake unit housing that receives the first intake element and the second intake unit has a second intake unit housing that is separate from the first housing and that receives the second intake element.
  • the draw-in element and further components of the draw-in unit may be mounted on a mounting plate.
  • the energy store of the first and / or second draw-in element is designed as a draw-in spring.
  • other types of energy storage mechanisms would also be possible.
  • the draw-in spring is a compression or tension spring.
  • the first and / or second retraction unit has a damper for damping the closing movement of the movable furniture part. It is possible, for example, for the first draw-in unit to have a damper and, in contrast, the second draw-in unit to be equipped more cost-effectively without a damper.
  • the energy store of the first pull-in element is larger than the energy store of the second pull-in element.
  • the spring force is the draw-in spring of the first feed unit is greater than the spring force of the feed spring of the second feed unit.
  • the Figures 1 to 6 show a preferred embodiment of the device according to the invention for closing a movable furniture part (not shown).
  • the device 11 can be used, for example, on a movable furniture part designed as a drawer. It is of course possible to use the device 11 on other movable furniture parts, for example on a door or on a flap.

  • the guide units 13 each have a body rail 14, which can be configured, for example, as a bent sheet metal component.
  • the body rail 14 has at least one, for example, two body brackets 15 arranged one behind the other in the longitudinal direction of the body rail 14, each of which has a mounting leg 16 which has several fastening holes 17, for example in a row, via which the body bracket 15 can be fastened with the aid of suitable fastening means can be fixed in position on an associated side wall (not shown) of a drawer receptacle formed in the furniture body.
  • the body brackets 15 each have a support section 18 protruding at an angle from the mounting leg 16, the support sections 18 of the body bracket 15 being connected by a rail element 19 also belonging to the body rail 14.
  • a middle rail is displaceable in the carcass rail 14 by means of bearing means stored.
  • Rolling bodies arranged in carriages 21 serve as bearing means, in particular rollers which run along a guide track formed on the body rail 14.
  • a running rail 22 which could also be referred to as a drawer rail, is again mounted displaceably relative to the middle rail 20 by means of bearing means in the form of carriages 21.
  • the running rail 22 is assigned to the drawer and runs in the depth direction of the drawer.
  • the combination of body rail 14, middle rail 20 and running rail 22 is called full extension.
  • guide units 13 without a central rail 20.
  • Two pull-in units 23, 24 are provided in order to move the running rail 22 together with the drawer into the closed position after a certain closing path has been covered, either automatically or with the aid of force.
  • a closing force is exerted on the drawer in the closing direction.
