Definitions

  • the present invention relates to an extension system for the power-assisted method of a linearly movably mounted on a body thrust element with a between the thrust element and the body mediating a force spring element.
  • pusher is used in the context of the present application on behalf of all elements that are retracted into a body and extended, such as drawers and drawers for living, kitchen, office and storage furniture, sanitary facilities, electronics cabinets, computer racks etc.
  • push elements also includes, for example, linearly movable parts in vehicles, for example drawers or console elements in cars.
  • body in connection with the present application refers to the mostly stationary counterpart to the linearly displaceably mounted thrust element.
  • the pull-out system serves to provide power assistance in the movement of a push element movably mounted on a carcass by means of a linear guide.
  • a linear guide may be a conventional plain bearing in a simple design or a roller or roller bearing or a ball bearing in a higher quality design.
  • Ball bearing telescopic slides are usually used for a comfortable and stable movement of push elements on a carcass.
  • the pusher element is moved between a fully extended position (off zugsendposition) and a fully inserted position (insertion end position) moved or moved.
  • Power assisted feed systems for linear guides have long been known and are constantly being developed. They usually provide the power assist on the last leg just before the plug-in end position.
  • the thrust element is first inserted by an operator to a predetermined insertion depth, from where then takes place on the last stretch of a force support when retracting through the feeder system to Einschubendposition. The operator then usually has to spend no more own power, but the rest of insertion or collection is accomplished by the feeder system alone.
  • the power assistance is usually done using spring forces.
  • a disadvantage of known feeder systems is that a locking element is biased held in a standby position and this must be brought to perform the power assisted feed with another element engaged or coupled. In the reverse direction of travel, it must be disengaged again or decoupled.
  • Such intake systems are mechanically complex, susceptible to failure and damage and practice only on the last stretch of a force in the direction of insertion, which starts only at a certain retraction position. The power assistance is thus abruptly when reaching this retraction position.
  • a support the extraction or extension of the push element is not provided by the known feeder systems.
  • the object of the present invention was thus to overcome the known disadvantages of the prior art.
  • the present invention can provide force assistance with both a single push-pull system on insertion in the push-in end position and on pull-out in the direction of the pull-out end position.
  • the provided on the thrust element first articulation point is spring-biased via the spring element with the body in combination.
  • the resilient bias thus exerts a force on the first articulation point on the push element from a support point on the carcass. If this force is not perpendicular to the direction of travel, it has a component acting parallel to the direction of travel, which acts either in the insertion direction or in the extension direction and provides a force assistance in this direction.
  • a second articulation point is provided on the carcass and the spring element is arranged between the first articulation point and the second articulation point, wherein the spring element is directed to increase the propriety between the first articulation point and the second articulation point exercises.
  • the spring element is connected to the body and there is provided a second pivot point, which is supported on the one hand via the spring element resiliently biased on the body and on the other hand connected via a push rod to the first pivot point.
  • a push rod is provided between the first articulation point and the second articulation point, which keeps the distance between the two articulation points constant.
  • the supported on the body spring force acts first on the - A -
  • the spring element comprises a compression spring, i. a spring in which the spring force causes an extension of the spring, preferably a gas spring or a coil spring.
  • the spring element comprises a gas spring with a cushioning, d. H. a damping device which exerts a damping effect in each case before reaching the insertion and / or Auszugendposition on the movement.
  • a hydraulically acting end position damping is particularly preferred.
  • the spring element comprises a tension spring, preferably a gas tension spring or a spiral tension spring.
  • means are provided which direct the spring force so that a thrust force is exerted on the first articulation point on the thrust element. This is particularly important in those embodiments in which not a compression spring is provided directly between the first articulation point on the thrust element and the second articulation point on the body. In the case of a tension spring, the tensile force which normally results in a shortening of the spring is to be deflected so that the spring force acts in the direction of an extension of the spring and thus of a thrust.
  • the force of the spring element acts perpendicular to the direction of travel of the push element.
  • a proportion of this force acting perpendicular to the travel direction at an angle to the push element for a power assisted retraction or extension is transmitted.
  • the spring force can act obliquely to the direction of travel of the thrust element, but the angle should not be more than 45 ° to the vertical, preferably not more than 20 ° to the direction of travel, otherwise in one direction parallel to the direction of travel thrust, in the opposite Direction, however, a train is exerted on the pusher. However, it is desirable that a thrust be exerted in both directions.
  • the extension of the thrust element takes place, starting from the Einschubendposition, initially under force against the bias of the spring element.
  • the spring force of the spring element counteracts the extension until the first articulation point in the direction of travel is at the same height as the second articulation point, ie, until the first articulation point is in a plane perpendicular to the linear travel path and through the second articulation point.
  • This position of the first articulation point is also referred to herein as the "dead center" of the force assisted method
  • the force of the spring element exiting the spring element and acting on the first articulation point is perpendicular to the linear travel
  • the force on the push element no longer acts in the insertion direction, but in the extension direction and provides a force support for the pull-out.
  • the force support preferably acts on the pull-out until the pull-out end position.
  • the maximum extension of the thrust element is then determined or limited, inter alia, via the maximum travel.
  • the disengagement of the system with the body or pusher element may, for example, occur at the articulation points or within the spring element and is achieved by means known per se which are familiar to the person skilled in the art on the basis of his general expert knowledge. Such means for disabling or disengaging are not central to the present invention.

  • the pull-out system according to the invention is mounted in or parallel to the plane of the bottom plate.
  • the articulation points can be arranged on the bottom plate of the thrust element and a corresponding plate on the body.
