Definitions

  • the invention relates to a system for attaching a furniture leg to a piece of furniture and a method for attaching the furniture leg to the piece of furniture, in particular a system for attaching a furniture leg to a piece of furniture and a method for attaching the furniture leg to the piece of furniture, which enable simple assembly.
  • a customer purchases such furniture, it must be transported to the customer by the manufacturer, the wholesaler or the retailer. For space-saving transport, the furniture is transported disassembled into its individual parts. At the end customer, for example, the individual furniture legs have to be mounted on the furniture.
  • Constructions are known from the prior art by means of which a furniture leg can be attached to a piece of furniture without the aid of tools, for example by means of a latching device.
  • Such constructions according to the prior art have the disadvantage that the furniture legs attached to a piece of furniture are not fastened without play. This results in the furniture being susceptible to vibration.
  • a system for fastening a furniture leg to a piece of furniture has a fastening element which is adapted to be fastened to the furniture leg, and a holding element which is adapted to be fastened to the furniture.
  • the holding element has one on one side first projection and a second projection spaced apart from the first projection.
  • the fastening element has a first side, a second side adjoining the first side and a third side opposite the first side.
  • the fastening element has a recess which is open to the first side and which is designed to receive the first projection, a preloading surface extending from the second side along the third side and a stop surface adjoining the preloading surface and protruding from the third side.
  • the holding element with the first projection and the second projection, and the fastening element with the recess, the preloading surface and the stop surface are designed to ensure that the system is in a state in which the first projection is at a predetermined depth from the first side rests against the recess on both sides without play and the second projection rests against the prestressing surface and the stop surface without play, enabling the furniture leg to be fastened to the furniture without play.
  • Axles are easy and inexpensive to procure or manufacture and store, so that inexpensive manufacture is supported.
  • the first axis and the second axis are arranged protruding between opposite sides of the holding element, and the fastening element has two recesses, each of which is designed to receive the first axis, and two Preload surfaces and two stop surfaces, on each of which the second axis rests.
  • the axis can be easily and quickly mounted on the holding element.
  • the first projection rests against the recess at the predetermined depth from the first side and without play on both sides, and the second projection rests against the preload surface and the stop surface without play, i.e. in the assembled position, is through the two contact points an absolutely backlash-free and statically determined fixation possible.
  • At least one opening has an oval cross section.
  • the fastening element is set up so that a distance between a central axis of the first axis and the prestressing surface along the course of the prestressing surface from the second side to the stop surface is not constant, the first axis being at the predetermined depth and it rests against the recess on both sides without play.
  • the non-constant distance enables the system to be free of backlash in the position in which the second axis rests against the stop surface and without play against the preload surface, or that a preload force between the projections, the recess and the biasing surface is simply created in a desired manner by adjusting the distance accordingly in advance.
  • the preload surface has a first area, along which the distance increases from the second side, and a second area adjoining the first area, along which the distance decreases or remains constant starting from the second area stay on.
  • the behavior of the fastening element in relation to the holding element can be influenced during assembly. Since the distance increases in the first area, when the axis moves along the preload surface, there is either a gradual zero backlash or the preload force is applied in a controlled manner. In the second area, the freedom from backlash or the pretensioning force can simply be retained, since no force component acts to loosen the connection.
  • a transition from the first to the second area can be detected tactilely by a fitter, so that the fitter can detect when the fitter reaches the final position.
  • the recess has a dimension in the direction of the second side, which diminishes from the first side towards the third side.
  • Such a shape of the recess is easy to produce and the position of the first axis in which it rests against the recess from the first side at the predetermined depth and with no play on both sides can be easily determined by coordinating with the diameter of the axis.
  • the system has a locking device.
  • the locking device fixes the fastening element to the holding element in the state in which the first projection is in contact with the recess from the first side at a predetermined depth and on both sides and the second projection is in contact with the stop surface and without play on the preloading surface.
  • the position in which the second projection rests on the stop surface can be secured so that the play-free connection between the holding element and the fastening element is not released, for example, even when the table is raised on the table top.
  • the locking device is attached to the holding element and has a bolt that can be moved relative to the holding element and a biasing element which is set up to urge the bolt in a locking direction into a locking position in which the locking device is attached to the stop surface locked position of the second projection on.
  • the locking device is arranged on the holding element and designed such that the locking direction runs parallel to a direction of protrusion of the first and second protrusions. This arrangement makes it possible to subsequently release the lock ergonomically.
  • a method for fastening a furniture leg to a piece of furniture has the following steps: introducing the first projection of the holding element into the recess of the fastening element that is open towards the first side; Executing a pivoting movement between the fastening element and the retaining element so that the second projection of the retaining element moves along the preload surface, so that the first projection rests in the recess at the predetermined depth and on both sides without play and the second projection on the stop surface and without play on the Preload surface is applied.
  • This method makes it possible, with simple and inexpensive means, to mount the furniture leg on the furniture easily and without play.
  • the position in which the second projection rests against the stop surface is locked.
  • the position in which the second projection rests against the stop surface can be secured so that the connection between the holding element and the fastening element is not released, for example, even when the table is lifted on the table top.
  • the second projection is first moved into a first area of the prestressing surface in which a distance between a central axis of a first axis lying at the predetermined depth and free of play on both sides of the recess extends as the first projection and the prestressing surface the course of the biasing surface from the second side to the stop surface is enlarged.
  • a prestressing force is to be applied between the projections, the recess and the prestressing surface, or freedom from play is created.
  • the second projection moves in a second area of the prestressing surface in which the distance decreases or remains constant, in order to automatically maintain the position of the second projection lying against the stop surface.
  • a transition between the first and the second area of the prestressing surface can be detected in a tactile manner.
  • a fitter can be reported back by a noticeable and / or audible latch that a final assembly position, namely the position in which the second projection rests against the stop surface and the backlash-free connection is established, has been reached.
