Definitions

  • the invention relates to a catch fitting according to the preamble of claim 1.
  • Such locking fittings are used to pivot functional parts, such as backrests or headrests from a basic position in a modified support position.
  • the latching lever carrying the part to be pivoted is pivotable into different angular positions and can be locked against pivoting back there. From a pre-pivoted use end position, the functional part can be pivoted backward, for which purpose the lock is disabled.
  • a generic catch fitting is from the DE 83 18 928 U1 known.
  • a ratchet mechanism is provided therein, which consists of an external toothing of the locking lever and a locking member forming a pawl which engages in the locking position in a tooth gap of the external toothing of the locking lever.
  • the locking lever and the tab which is usually attached to a fixed furniture part to which the backrest or headrest is pivotable, are on one mounted common pivot axis, wherein the tab covers the formed head of the locking lever.
  • Another catch fitting of the generic type is from the EP 1 510 150 B1 known.
  • This known detent fitting has a first arm provided with a housing portion and a second arm connected to a housing portion of the first arm so as to oscillate about a first axis, the second arm being provided with a gear portion.
  • a wedge element is provided in the known catch fitting, which is floatingly mounted loosely arranged in a window of the housing portion and in the locked position engages with its one toothed end face in the gear portion of the second arm.
  • at the other end face of the wedge member there is a contact surface which contacts a wedge surface so as to restrain the second arm in its mobility so as to oscillate in a direction extending with respect to the first arm.
  • the gear portion of the wedge member is formed so that it has the first axis as the center.
  • the invention is therefore based on the object, a cost-producible latching fitting of the generic type with structurally little effort so that he can be adjusted reliably and accurately.
  • this pressure nose is also mounted on the pivot axis.
  • the pivoting movement is limited to a starting position of the locking lever by a stopper bolt connected thereto, which is guided in a backdrop of the tab.
  • the invention allows a very fine pitch of the teeth, whereby the number of locking positions relative to the locking fitting according to the prior art substantially increased, with the result of a comfort improvement.
  • the new locking fitting is characterized by its manufacturing technology extremely simple implementation, which leads to a very cost-effective production.
  • the dimensions of the new detent fitting are reduced compared to the known, resulting in an improved use in the corresponding furniture.
  • a detent fitting in particular for adjustable backrest parts of a sitting or lying furniture is shown, which has a tab 2 and a pivotable about a pivot axis 5 locking lever 1.
  • the locking lever 1 is formed in the pivot axis 5 facing the end portion as a circular arc-shaped head 3 with an external toothing 4 and in the direction of arrow ( FIG. 3 ), according to the number of teeth of the external teeth 4 in locking positions.
  • a wedge-shaped locking member 6 is provided, which is provided on the one hand with teeth 7 which engage in the external teeth 4 of the head 3 and the displaceable on an opposite side to a stop edge 9 of the tab 2 is applied.
  • This so-called retraction movement of the locking member 6 is supported by a compression spring 8, which is supported on the one hand on an outer edge of the locking member 6 and on the other hand on the tab 2.
  • the pin 10 serves the disengagement of the locking member 6 from its Verkeil too to intimidzuschwenken the locking lever 1 from a pivoted end position in a starting position.
  • the pin 10 corresponds, as in the FIGS. 4 and 5 is very clearly visible, with a mounted on the pivot axis 5 pressure nose 14th
  • pressure pins 15 are fixed to the locking lever 1, on both sides of the pressure nose 14, which are opposite each other.
  • the locking lever 1 is pivoted, with respective blocking in the individual, predetermined by the number of teeth locking positions, to an end position, which is approximately in the FIG. 5 equivalent.
  • a circular arc-shaped, concentric gate 11 is provided, in which a stop pin 12 of the locking lever 1 is guided, wherein the length of the gate 11 limits the pivoting of the locking lever 1.
  • the pivoting movement of the locking lever 1 can also be limited by the pressure pins 15, wherein in the FIG. 4 recognizable left pressure pin 15 comes in an end position against a stop 16 of the tab 2 to the plant, while the right pressure pin 15 abuts in the other end position of the pressure nose 14, which in turn is limited in its pivoting, as shown in the FIG. 5 is clarified.
  • the pressure pins 15 can be dispensed with the backdrop 11 and the stopper pin 12.
