Definitions

  • the invention relates to the nut of a door or window lock or door or window gear with a square channel formed concentrically to the axis of rotation of the nut for receiving a square mandrel, which connects at least one handle to the nut, with one side of the square mandrel and the square channel radially to the axis of rotation resilient element is used with bias.
  • a door lock of this type is known from a brochure from Hoppe AG.
  • a groove and recesses are incorporated on one side of the square mandrel for receiving a leaf spring.
  • the leaf spring extends almost the entire length of the square mandrel and is angled at one end towards one side. These bends engage in radial recesses of the square mandrel, which are attached to the ends of the groove.
  • This leaf spring has the effect that the play of the square mandrel in the square channel of the nut and the handle is reduced.
  • this design has the disadvantage that a specially machined square mandrel is used and that a complete freedom from play cannot be achieved with it.
  • the invention has for its object to design the nut of a door or window lock or a door or window gear so that the square mandrel connecting the nut to the handle is kept free of play in the nut while maintaining the usual manufacturing tolerances.
  • recesses are formed in at least two mutually perpendicular sides of the square channel, in which resilient elements are arranged radially to the axis of rotation of the nut.
  • the nut of a door or window lock is always a cast metal part, dimensional deviations cannot be avoided with inexpensive manufacture.
  • the deviations are in the range of about 1/10 mm.
  • the dimensions of the square mandrel also vary by 0.08 mm. This, in the manufacture of the nut and the square mandrel inevitable dimensional deviations and the resulting play of the square mandrel in the square channel of the nut is disturbing for door and window locks and gears, because on the one hand the handle can not be mounted exactly horizontally, so that aesthetic appearance is disturbed and, on the other hand, rattling noises occur when the door handle is operated.
  • the recesses in the nut for receiving the radially resilient elements are taken into account when casting the nut, so that there are no additional costs for their production.
  • the elements which are only resilient by 1/10 mm in the radial direction, can be injection-molded plastic parts or stamped sheet metal parts, the production of which causes low costs.
  • the resilient elements are formed by a frame-like plastic part which can be inserted axially into a recess in the nut and which ensures that the square mandrel is mounted in the nut without play.
  • the plastic used also has the effect that damping takes place and no noise between square and nut can occur.
  • the radially resilient elements are formed by spring tongues of a sheet steel part placed on the side.
  • the recesses in the nut can also be provided in such a way that axially extending leaf springs can be inserted or clipped into the nut.
  • Fig. 1 shows a mortise lock 1 with a cuff 2, a latch 3, a bolt 4 and a nut 5.
  • the nut 5 contains a square channel 11 for receiving a square mandrel 6, which connects the handle 7 to the nut 5.
  • a second pusher 7 ' can also be connected to the nut 5.
  • a fixed handle 10 can also be provided instead of the second handle 7 '.
  • the pushers 7 and 7 ' are rotatably mounted in the shield 9 and 9', respectively.
  • the nut 5 is mounted in the housing walls 8, 8 'of the mortise lock 1 so as to be pivotable about the axis of rotation 20.
  • the nut 5 is provided with at least one lever for moving the latch 3 or for moving a linkage.
  • FIG 3 shows, on both sides of the nut 5 recesses 14 are provided, into each of which a frame-like plastic part 16 can be inserted.
  • the recesses 14 extending over the four sides of the square channel 11 at the ends of the square channel 11 take the frame-like plastic part 16 pinching up.
  • the four side profiles 15 and 15 'of the frame-like plastic part 16 form the radially resilient elements. Since the travel is extremely small, it is not visible in the drawing.
  • the four side profiles 15 and 15 'of the plastic part 16 are, starting from the corner areas, arched inwards so that they rest with prestress on the walls of the square mandrel 6 and the nut 5 after insertion of the square mandrel 6 and keep the square mandrel 6 free of play.
  • an inlet tongue 18 is formed on each side profile 15, 15 'of the frame-like plastic part 16, which extends only over the central region of each side of the square channel 11 and which extends the guidance of the square mandrel 11 in the plastic part 16 .
  • These inlet tongues 18 have the further advantage that the square mandrel 6 can be pushed not only from the side through the nut 5, into which a plastic part 16 is inserted and a strongly chamfered edge 17 is provided, but also from the other side because of the Square mandrel 6 with its tapered tip clamps the inlet tongues 18 in the nut. This prevents the plastic part 16 from being pushed out of the recess 14 when the square mandrel 16 is inserted. For this reason, it is also possible to use a plastic part 16 in both sides of the nut 5, regardless of the question from which side the square mandrel 6 is pushed through the nut 5.
  • arcuate recesses 21 are provided in the central region of the outer sides of the side profiles of the frame-like plastic part 16. These recesses 21 cause the side profiles 15 and 15 'to have an inward curvature when the plastic injection molded part 16 cools down.
  • Small axially extending ribs 19 are provided on the outer sides of the plastic part 16, which serve to ensure that the plastic part 16 can be inserted into the recess 14 without play despite the manufacturing tolerances that cannot be avoided because the protruding parts of the ribs 19 are squeezed or sheared off.
  • the radially resilient elements of spring tongues 23 and 23 'of a sheet steel part 22 are formed here. Rectangular recesses 28 and 28 'are formed in at least one end of the square channel 11 in the central region of the sides 12 and 13 or on all four sides and accommodate the resilient tongues 23 and 23' of the sheet steel part to be arranged on one side of the nut 5 '.
  • the sheet metal part forms a spring cup 22 encompassing the bearing pin 26 of the nut 5 ', four spring tongues 23, 23' being angled from the base 24 of the pot.
  • the spring cup 22 has on the free edge of the pot casing 25 a collar 27 parallel to the pot base 24. When inserting the nut between the housing wall 8, 8 ', this collar 27 is held by a housing wall 8 or 8', so that the spring cup 22 with its spring tongues cannot be pushed out of the square channel 11 of the nut 5 'when a square mandrel is inserted .
  • the spring cup 22 also serves to support the nut 5 'in the housing wall 8' of the lock.
  • the spring cup can also be arranged on both sides of the nut 5 '.
  • the radially resilient elements are each formed by a leaf spring 30 and 30 'which is angled like a hook at its two ends.
  • the recess for receiving this leaf spring 30 and 30 ' is a flat, in the central region of the side walls 12 and 13th formed parallel to the axis of rotation 20 groove 34, at both ends of which radial recesses 32 are provided for receiving the hook-like bend 31.
  • beads 33 are provided, via which the leaf springs 30, 30 'can be clipped on with their bends 31.
  • leaf springs 30 and 30 ' are provided.
  • four such leaf springs can also be provided on the four sides of the square channel.
