Definitions

  • the invention relates to a pull-out guide for pull-outs from a body, with two mutually slidably guided in the pull-out guide rails, of which the outer overlaps the inner C-shaped and of which the inner is either connected to the pull-out or the body.
  • the two guide rails are preferably guided displaceably against one another by means of roller bodies mounted in a roller body cage.
  • pull-out guides have the disadvantage that when the inner guide rail is firmly held on the pull-out or on the body and the outer guide rail is firmly held on the body or pull-out, the pull-out cannot be completely pulled out of the body, since the rolling body cage has a length that cannot be neglected which the two guide rails must still be arranged overlapping in their extended position.
  • the invention is therefore based on the object of improving a pull-out guide of the type described at the outset in such a way that full pull-out can be achieved with the simplest and cheapest possible means.
  • the outer guide rail is displaceably guided at least two points apart from one another by at least one holding piece parallel to the pull-out direction, that the holding piece can be firmly connected to the body or the pull-out, that the outer guide rail is held by the holding piece its top and bottom is guided that with the outer guide rail with the holding piece cooperating stop elements are provided and that the stop elements are arranged so that they move the outer guide rail relative to the holding piece from an insertion end position, in which the extract fully into the Body is pushed in, allow in a pull-out end position in which the pull-out is fully pulled out of the body when the guide rails are pulled out to the maximum.
  • the joke of the invention is thus to be seen in the fact that, unlike the known full extension rails, a further guide rail is provided, but that one only starts from two slidably guided guide rails and only the outer guide rail is in turn slidably supported in a holding piece, which at the same time serves to fasten the entire pull-out guide to the part to which the inner guide rail is not fastened .
  • the holding piece supports the outer guide rail at two points arranged at a distance from one another.
  • the outer guide rail is supported at each of the two spaced-apart locations by a respective holding piece, ie a total of two holding pieces.
  • the outer guide rail is indirect, i.e. via intermediate links, supported by the holding piece.
  • a particularly simple solution is one in which the holding piece supports the outer guide rail directly on its top and bottom.
  • the holding piece rests on the upper and lower side of the outer guide rail, with upper and lower supporting surfaces curved in the pull-out direction has, so that on the top and bottom of the outer guide rail the support surfaces are essentially only linear and thus jamming is prevented.
  • the support surfaces have an apex and if the apices of the upper and lower support elements each lie on a perpendicular which is at right angles to the direction of extension, i.e. are not offset from each other. With this arrangement, jamming of the outer guide rail in the holding pieces can be prevented particularly advantageously.
  • the design of the support elements no further details have been given above.
  • the lower support surface is formed by a roller, so that when the pull-out is pushed in in the last piece before reaching the insertion end position, in which the outer guide rail essentially extends from the lower one Support elements is worn, the outer guide rail can slide easily in the holding piece.
  • rollers it has also proven to be advantageous if the roller has an axis of rotation which intersects the perpendicular through the vertices of the support surfaces.
  • the support surfaces are sliding surfaces, that is to say that the support surfaces consist of a good fit on the outer guide rail sliding material, preferably a plastic material, are formed.
  • the support elements should primarily support the outer guide rail upwards and downwards.
  • the holding pieces have a support surface which is adapted to a cross section of the top and bottom of the outer guide rail, so that they also serve as side guides for the outer guide rail and thus guide them on all sides.
  • a cost-effective solution also comes about if the two holding pieces assigned to the outer guide rail are of identical design, so that only one type of holding piece has to be produced.
  • the solution according to the invention can be used with all types of pull-out guides.
  • one embodiment of the solution according to the invention offers particular advantages in which the holding piece can be fastened to the body via a spacer and in which the spacer holds the holding piece at a distance from the body.
  • This solution is intended for pull-out guides with concealed guide rails, that is to say, guide rails which are arranged in a cavity in a side wall of a pull-out.
  • the inner guide rail is preferably firmly connected to the respective extension and holders are generally required, to connect the concealed outer guide rail to the body.
  • the holders which are required anyway can thus be replaced by the holding pieces according to the invention, so that full extension can be achieved at the same time and thus the costs of this exemplary embodiment of the solution according to the invention rise only insignificantly above the costs of a pull-out guide with concealed guide rails according to the prior art.
  • the holding piece is part of a side wall of the pull-out, and thus the inner guide rail is connected to the body while the Holding piece as part of the side wall of the pull-out is displaceable relative to the outer guide rail.
  • This solution can also be advantageously integrated into drawers with concealed guide rails.
  • the holding piece is integrally formed on the side wall, i.e. is an integral part of the side wall
  • a bottom of the pull-out piece is integrally formed on the side wall, so that the bottom side wall and holding piece are a one-piece and inexpensive to manufacture Represent part.
  • the pull-out guide is provided with at least one slide.
  • the holding piece has a slideway for the slider.
  • the holding piece forms a longitudinal member for the pull-out, so that this longitudinal member is already part of the pull-out and a relatively simple structural solution for the pull-out is possible.
  • one of the stop elements is arranged on the holding piece.
  • the holding piece has a shock-absorbing stop element.
  • Such a holding piece can be realized particularly easily if the stop element comprises elastic segments.
  • the holding piece is made of plastic, it is expedient for manufacturing reasons if the stop element is integrally formed on the holding piece, so that the entire part can then be produced particularly simply and inexpensively.
  • the longitudinal member is provided with a stop element.
  • the longitudinal member is preferably designed such that it comprises a movable tongue with an abutment surface, the latter protruding spring-loaded into an interior thereof.
  • the outer guide rail has a front stop cooperating in the inserted end position with the stop body of the front holding piece and a rear stop interacting in the extended end position with the stop body of the rear holding piece, so that the holding pieces, for example, after the Attach one stop can be pushed onto the outer guide rail and then the other stop is brought into position.
  • the pull-out guide according to the invention is particularly easy to handle when a rear stop can be moved out of a position interacting with the stop body against the force of a spring element.
  • the rear stop is a nose held on the spring element and projecting beyond the outer guide rail.
  • the nose has an insertion slope that decreases in the direction of insertion towards the guide rail, so that only the outer guide rail into the already assembled holding piece must be inserted.
  • the spring element is a leaf spring.
  • an advantageous exemplary embodiment provides that a front holding piece carries a front support for the front pull-out, which can be attached without great additional costs and thus shows all the advantages in this regard, in particular in the case of guide rails which are connected to one another in the insertion end position Rolling bodies standing approximately in the middle of the guide rail are mounted.
  • This front support is preferably arranged such that it projects from the holding piece on a side facing away from the body.
  • the front support is a projection formed in the area of the lower support element, which can then easily reach under the pull-out.
  • front support With regard to the type of front support, several options are conceivable. For example, in the case of pull-out guides which are to run as easily as possible into the insertion end position, it is advantageous if the front support has a support surface which runs essentially parallel to the pull-out direction, so that no force is required to make the front support effective.
  • the front support has a support surface which rises in the insertion direction, on which the pull-out can then slide and which thus fully supports the extension in the insertion end position.
  • the front holding piece in particular in the exemplary embodiment in which the lower support elements are designed at least as rollers, it is appropriate for the front holding piece to have a pull-in element by means of which the pull-out can detect a pull-in distance before the end of insertion position and acted upon by a force component of a spring is displaceable into the insertion end position.
  • a pull-in element by means of which the pull-out can detect a pull-in distance before the end of insertion position and acted upon by a force component of a spring is displaceable into the insertion end position.
  • the pull-in element is a swivel lever on which the spring engages in such a way that it moves from the end of insertion position against a first force component to a dead center, in which it experiences no force component in one direction of movement, and from this with the participation of a second force component in a pull-out position and vice versa and that the pivot lever is coupled during this movement with the movement of the pull-out via a cooperating connecting member.
  • a pivoting range from the dead center to the end of insertion position is substantially larger than a pivoting range from the dead center to the pull-out position, in particular if the latter is so close to the dead center that the pivot lever in the pull-out position still remains securely in this position.
  • connection between the pivot lever and the pull-out can be realized particularly easily if the pivot lever has a fork into which the connecting element can be inserted, so that the connecting element interacts with the pivot lever over the draw-in distance, but the remaining pull-out distance without interaction with the pivot lever can drive through.
  • the connecting member is a cam that can be inserted into the fork.
