Definitions

  • the invention relates to an espagnolette element for espagnolette fittings according to the preamble of claim 1 and a method for producing such a drive rod element according to the preamble of claim 3.
  • a generic drive rod element is from EP-0 560 016 A2 known.
  • the drive rod element is part of one Espagnolette fitting for window and door fittings and serves as a connecting rod coupling piece, e.g. in a corner drive a window fitting, with at both ends of the flexible deflection member of the corner deflection such a drive rod element attached for connecting drive rods can be.
  • the drive rod element consists of a cross section flat-rectangular rod material, one at one end Has coupling section.
  • the coupling section itself has a U-shaped cross section, being on the inside the U-flanges have fine teeth.
  • this fine toothing can be a complementary fine toothing on the narrow sides of a connecting rod to be coupled intervention.
  • pushing and pulling forces from Handle part of the window over the connecting rod on the connecting rod element and thus transferred to the corner drive will. It is also possible to easily release the clutch and reattach it. Manufacturing tolerances can also and compensated for different installation conditions be by the fine toothing of the drive rod element and the drive rod in different degrees of engagement to be brought.
  • such a drive rod element from a flat material strip, e.g. a strip cut, by embossing and subsequent bending deformation educated.
  • a flat material strip e.g. a strip cut
  • embossing and subsequent bending deformation educated There are at least two steps involved necessary. First, the end section of the rod material pressed flat and the fine toothing on the top embossed, then the two side sections bent up at right angles to form the U-profile.
  • the bending deformation can result in warping of the embossed fine teeth in the transition area, the proper engagement of the drive rod to be coupled and affect their flat support on the bottom of the U-profile can.
  • FR-A-2 403 441 is a further generic drive rod coupling for connecting a connecting rod or faceplate with the fitting corner element disclosed.
  • a length-adjustable tooth coupling is used proposed with a toothed coupling member on the coupling side End of the cut faceplate or drive rod via a pin-hole connection is connected to this.
  • Such a clutch has the Disadvantage that the coupling member is not in one piece with the drive rod is connected, but after cutting the connecting rod to this only has to be connected before it is connected to the coupling counterpart Intervention can be brought.
  • Driving rod and coupling piece can therefore not be produced in one process step.
  • the object of the invention is a generic Espagnolette element and a method for its production to create which in a simple manner in a single Work step with high precision can.
  • the drive rod element according to the invention can be faster and can be manufactured more cost-effectively and with greater precision than previously known.
  • Another advantage is that the method according to the invention which comprises only one work step, can be done with a single device.
  • the embodiment shows the drive rod element 1 according to the invention the embodiment consists of a cross section flat-rectangular metal rod material.
  • the embodiment consists of a cross section flat-rectangular metal rod material.
  • the two U-flanges 5, 7 run parallel to the Side edges of the flat rectangular bar cross section and have an internal fine toothing 9, 11.
  • an external fine toothing 13, 15 of the same pitch is provided, so that each U-flange 5, 7 essentially has a uniform thickness and runs in a zigzag shape.
  • the drive rod element is preferably 1 so adapted to the drive rod that the U-flanges 5, 7 have a height which is the thickness of the Driving rod corresponds.
  • Fig. 2 is a section along the lines II-II through the drive rod element 1 shown in FIG. 1. Here are the opposing internal gears 9, 11 of the Flanks 5, 7 of the U flange can be seen.
  • Fig. 3 shows a section along the marked with III Line in Fig. 1.
  • the part is of the first end region 3, in which the U-flange is trained.
  • FIG. 4 is the initial situation shown in a cross-section flat-rectangular rod material la between a stamp 21 and a die 23 is arranged.
  • On both sides of the rod material 1a are embossing jaws movable in the transverse direction 25, 27 arranged.
  • the arrows ⁇ , ⁇ and ⁇ show the Direction of movement of the stamping jaws and the stamp.
  • the stamp 21 is on its side surfaces with a tooth profile 33 provided.
  • the stamping jaws with a complementary one Fine tooth profile 37 on their in cross section flat rectangular rod material facing side surfaces fitted.
  • the reference numeral 35 denotes a lower one complementary fine tooth profile that on the inner Flanks of the recess 23a of the die 23 is formed.
  • the procedure is as follows.
  • the flat rectangular in cross section Rod material la is by the stamp 21 in the die 23 pressed.
  • the stamping jaws 25, 27 moved against the embossed sections so that in cooperation with the complementary side tooth profile 33 of the stamp the inner fine teeth 9, 11 of the connecting rod element 1 is stamped on the U-flanges 5, 7 will.
  • the stamp 21 its end position while the Embossed jaws 25, 27 are not yet in contact with the highly embossed Sections are.
  • This situation is shown in Fig. 5 and can be easily realized by using the Embossing jaws 25, 27 along the directions ⁇ and ⁇ with a move at a lower speed than the punch 21 along the direction ⁇ .
  • the flow of the material is supported, and simplifies the manufacture of the drive rod element.
