Definitions

  • the invention relates to a drawer slide with automatic feeder according to the General term of the independent claim.
  • Such drawer guides with automatic feed have the purpose of a Drawer inside a drawer guide in an opening of a Automatically pull in the cabinet. If the user put the drawer in retracts the furniture body, then the automatic feeder is in the last area retracting the drawer so effectively that the drawer without further effort of the user is drawn into the furniture body and is held there. If the drawer is then opened again, the Users first overcome the closed holding force of the automatic feeder and then continue against the pulling force of the automatic feeder open until the point at which the automatic feeder becomes ineffective again.
  • the object of the present invention is to have a drawer slide To provide automatic feeder, the feed spring a cheaper Has force curve than in the prior art.
  • the initial Pull-in force of the pull-in spring which acts on the drawer to be closed, should not be larger than that at the end of the closing process on the Drawer holding force.
  • An essential feature here is that as an automatic feeder for the drawer on the drawer guide a two-armed lever that can be rotated around a pivot bearing is arranged, the first lever arm by the rotary movement one in Dependency of the closed position existing positive and / or frictional connection between a linearly moving part and a forms the body-fixed part of the drawer guide, and the second Lever arm is attached to a first end of the retraction spring, and the second end the feed spring spaced therefrom under spring preload on a linear Moving or fixed part of the drawer guide is attached, wherein when inserting the drawer through the positive locking of the first Lever arm of the lever from a rest position over a dead center position in one Automatic position is rotated in which, with further rotation of the lever preloaded spring on the second lever arm automatically shortened and thus the Drawer guide and drawer are pulled into the cabinet opening.
  • the drawer guide with the automatic feeder is that after snapping the dead center position of the lever, the Spring force of the retraction spring acts on the rotating lever in such a way that the torque on the lever with increasing feed distance Drawer increases. This ensures that the drawer acting pull-in force that is directly proportional to the torque on the lever is small at the beginning of the pulling in, with increasing moving-in distance becomes larger and the holding force in the fully retracted state of the Drawer is largest.
  • the two-armed lever rotatably attached to a moving part of the drawer guide especially on the decor of the drawer or the drawer slide itself first lever arm of the two-armed lever is then from a certain Closed position of the drawer by a fixed stop on the Body rail or on the body angle in positive engagement with it or brought this. If the drawer is inserted further into the Furniture body then turns the two-armed lever over a dead center position and the feed mechanism starts automatically by turning the two-armed lever around the pivot bearing. This is due to automatic shortening the biased feed spring, which with its first end on second lifting alarm is attached and with its second end to the decor of the Drawer or the drawer slide itself, like the two-armed one Lever.
  • the two-armed lever also on another moving part of the Drawer guide can be rotatably arranged, such as the Middle rail (with a full extension) or on synchronous racks of the linear moving carriage (if any) or on any other linearly moving part of the drawer slide.
  • the attachment of the fixed stop for the positive Coupling between the two-armed lever and a fixed part of the Drawer guide can be chosen arbitrarily.
  • the stop can not only on the cabinet rail or cabinet angle, but e.g. also on the synchronous racks of the fixed carriage (if available) or on any other fixed part of the drawer slide.
  • the kinematic Reversal of the first embodiment of the invention can be claimed.
  • the two-armed lever can be rotated at any fixed or Body-fixed part of the drawer guide attached, especially on the Carcase rail or on the carcase angle.
  • the first arm of the two-armed lever is then from a certain closed position of the drawer by a linear moving stop on the decor of the drawer or the drawer slide even brought into positive engagement with it.
  • the feed spring is there fastened again with its first end to the second lifting alarm and with hers but the second end at any fixed or body-fixed part of the Drawer guide, especially on the cabinet rail or on Body angle, like the two-armed lever itself.
  • lever and the suspension point of the second end of the spring are attached to the same component. But this is not absolutely necessary, so that in the first version e.g. also the lever on Decor and the second end of the spring to be attached to the drawer rail can or vice versa, and in the second embodiment e.g. the lever on the Body rail and the second end of the spring attached to the body bracket can be or vice versa. It is only important that there is no relative movement between the pivot point of the two-armed lever and the attachment point of the Spring on one of the drawer parts takes place, otherwise the spring is constantly in would proceed to its shortest state.
  • the point of attachment of the spring to one of the drawer parts lies here preferably in a common horizontal and / or vertical plane the fulcrum of the two-armed lever, but this is not a solution is because other positions outside of these levels are possible.
  • pivot bearing of the lever as well as the Fastening point of the spring on the second lever arm in the direction of insertion seen in front of the point of attachment of the spring on the linearly moved or fixed part of the drawer guide is arranged. It is also preferred that the point of attachment of the spring on the second lever arm in The direction of insertion is always in front of the Pivot bearing, or at most directly vertically above it. Of course, too all other relative arrangements of the pivot bearing and the points of attack the spring possible.
  • the design of the two-armed lever is preferably designed such that the both lever arms have different lengths.
  • the ratio of Lever arm lengths are preferably between 2 and 3, depending on the drawer the longer first lever arm forms the positive connection and the shorter second one Lever arm forms the attachment point for one end of the spring and thus the torque of the lever or the pulling force of the drawer.
  • the angle between the lever arms is approximately 120 °, including angles slightly below or above 120 °, e.g. 100 °, 110 °, 130 ° or 140 °.
  • the dead center position (rest position) in which the automatic feeder does not work is for the short second lever arm at approx. minus 10 °, which angle then must be overcome against the pulling force of the spring until the Automatic feeder starts to work at or above dead center. Can too other angles between about minus 1 ° and minus 30 ° may be provided, the one unintentional triggering of the automatic feeder or an unintentional Should prevent the lever from rotating.
  • the long first lever is then included approx. minus 135 °.
  • the short second lever with the spring application point is included about plus 45 ° and the long first lever at about minus 80 °.
  • the length of the spring corresponds approximately to the length of the first lever arm, which enables favorable lever ratios and spring dimensions.
  • Rotary stops are provided for the end positions of the lever. The rotary stop for the position of the lever when the drawer is completely retracted can be included by the stop for triggering the automatic feeder.
  • This stop for triggering the automatic feeder has one Recess in which the long second lever arm can engage and at completely retracted state of the drawer canted there so that a further insertion of the drawer is not possible.
  • This recess will delimited by a low and a high wall, the lower wall in Insertion direction is and when inserting the drawer through the long Lever is run over. If the drawer is retracted further then the long levers on an incline of the high wall so that the lever starts rotating.
  • the two-armed lever In the disengaged, inactive position of the retraction mechanism, i.e. when the drawer has been pulled out of the opening of the body sufficiently, the two-armed lever is in a position slightly above the dead center of the maximum deflection of the spring.
  • the drawer If the drawer is now inserted into the opening of the body, it runs the two-armed lever on the stop and the two-armed lever begins to turn his pivot.
  • the spring will pull itself out of its maximally extended position from the dead center with maximum spring preload with a lever distance equal to zero in a shorter one Position together with optimal / maximum lever distance. In this condition then the (less dead center) spring force acts on you optimal / maximum lever distance, so that when retracted the drawer has the optimal, possibly maximum torque on the lever and thus the optimal, possibly maximum pull-in force on the drawer.
  • the two-armed lever of the Automatic feeder can also be provided with a damping of its movement, which is a subdued, harmonious linear retraction movement of the drawer in causes the opening of the furniture body.
  • a damping of its movement which is a subdued, harmonious linear retraction movement of the drawer in causes the opening of the furniture body.
  • the damping in Area of the pivot bearing of the two-armed lever in the form of a Rotation damper used but all other damping principles according to the prior art from the present invention should.
