Definitions

  • the invention relates to a drawer pull-out guide with at least one drawer rail of the type to be described, as well as a piece of furniture with a furniture body and a drawer that is movably mounted relative to the furniture body. Furthermore, the invention relates to a method for connecting a first rail to a second rail of a drawer rail on a drawer pull-out guide.
  • a locking device for releasably attaching drawers to an extendable guide rail of a drawer pull-out guide, the drawer being placed on the guide rail during assembly and being pushed backwards until a by a spring-loaded locking bar automatically engages in a locking opening of the drawer.
  • This ensures that the drawer is mounted immovably relative to the guide rail in normal operation.
  • the latching bolt In the installed position, the latching bolt is mounted so that it can be displaced linearly in a vertical direction and has a handle at the lower end region, the locking between the drawer and the guide rail being able to be released by manually pulling the latching bolt downwards.
  • the disadvantage of this is that the installation space for the drawer pull-out guide has to be dimensioned to be relatively large due to the locking bolt projecting downwards.
  • U1 shows a drawer pull-out guide with a body rail to be fastened to a furniture body, a drawer rail to be fastened to a drawer and with a center rail which is movably mounted between the body rail and the drawer rail.
  • An elastic pressing element in the form of a spring tongue is arranged at the front end of the drawer rail, which can be bent upwards when the drawer is pushed onto the drawer rail and then locks the drawer relative to the drawer rail.
  • the disadvantage of this is that the spring tongue is visible even when the drawer is installed.
  • a drawer assembly having a drawer slide and a drawer side wall, with a support rail fixedly connected to the drawer side wall.
  • an actuator is pivotally mounted, which at Sliding the drawer side wall can be releasably locked with the drawer rail of the drawer extension guide.
  • each drawer has to be equipped with an actuating element for locking with the drawer extension guide.
  • the object of the present invention is to specify a drawer rail of the type mentioned at the outset while avoiding the disadvantages discussed above.
  • the locking element is arranged on the second rail and when the first rail is pushed onto the second rail, starting from the locking position, against the force of the energy accumulator about an axis that runs horizontally in the installed position in the direction of the cabinet rail or the center rail of the drawer pull-out guide can be pivoted into a release position.
  • the locking element is pivotably mounted about a horizontally running axis when the drawer rail is in a mounting position, so that the drawer can be placed on the first rail during assembly on the drawer pull-out guide and moved backwards until the locking element is pushed against the force by the weight of the drawer of the force accumulator dodges down in the direction of the release position and the drawer at a continued insertion movement can be releasably locked by the force of the force accumulator.
  • the feature of the locking element which is mounted pivotably about a horizontally extending axis in the mounting position of the drawer rail, is based on the initially mentioned DE 198 28 718 A1 also not an obvious measure, because the downwardly projecting handle according to the DE 198 28 718 A1 is an essential technical feature for releasing the lock between the drawer and the guide rail.
  • An advantage of the invention lies in the fact that the first rail arranged on the drawer does not require a suspension stroke in a vertical direction when it is pushed onto the second rail. During assembly, the drawer can therefore be slid onto the second rail in a horizontal plane until the locking element first deflects downwards and then snaps up again by the force of the energy accumulator, thereby automatically locking the drawer relative to the second rail.
  • the locking element is mounted on the second rail.
  • the locking element on a front end of the second rail is movably mounted.
  • the locking element is guided through an opening in the second rail. This results in a compact and optically unobtrusive design because the locking element is arranged for the most part within a rail cross-section of a rail and only the part of the locking element provided for locking protrudes from the second rail. Provision is preferably made for the opening to be arranged on a central web of the second rail, which web preferably runs horizontally in the installed position.
  • the at least one locking element and the force accumulator can be designed in one piece together or else be designed as components that are separate from one another.
  • the energy accumulator can be formed by a material elasticity of a plastic part.

Due to the interaction of the rail 12 with the second stop surface 37b of the locking element 21, the second rail 12 can be pulled from a fully closed position into an open position.
