Definitions

  • a length-adjustable linkage coupling of connecting rod fittings for windows, doors or the like of the aforementioned type is already known from DE-PS 26 35 446. It has also proven itself in practical use due to its high dimensional stability.
  • the linkage having the clutch shoe must be manufactured by stamping presses from a sheet metal blank which, in the area of the U-shaped clutch shoe to be produced, has a wing projecting beyond the normal width of the linkage on both sides, the width of which is approximately the later Height of the resulting U-leg of the finished clutch shoe corresponds.
  • the starting material for the production of the linkage provided with the coupling shoe must therefore have a correspondingly larger width than the linkage which was produced later.
  • DE-OS 26 35 708 has already made the proposal to manufacture the clutch shoe for itself by stamping presses from a sheet metal blank and then to connect it to the rod part, for example by riveting.
  • the sheet metal blanks for the clutch shoes are produced from sheet metal strips, the starting dimensions of which are considerably larger than the sheet metal blank required for producing the clutch shoe.
  • This known length-adjustable linkage coupling is indeed suitable for the positive connection of two partially overlapping faceplate sections of espagnolette fittings, which are otherwise fixed to a support component, for example, to the sash of a window or a door, in each case by several screws against displacement.
  • clutch shoes by DE-GM 76 03 047 e.g. for connecting the faceplate of espagnolette fittings, to become known type for the formation of length-adjustable link couplings between displaceable espagnolettes of such espagnolette fittings.
  • the clutch shoes are subject to constantly changing longitudinal thrust forces, it has been shown that if the fittings are not always difficult to avoid, undesirable damage or at least deformations to the clutch shoes can occur, which have a lasting effect on the continuous use of the drive rod fittings equipped with them.
  • the invention has for its object to provide a linkage coupling of the type specified, in which a flat material strip, in particular a strip of steel strip, can be used as the starting material for the manufacture of the linkage having the coupling shoe, which has the same width dimension over its entire length.
  • the coupling shoe is to be provided within the initial width of the band material with U-legs projecting over its broad side and integrally connected to the linkage over its entire length and having the molded fine toothing on its inner surface.
  • the side wings required to form the U-legs of the clutch shoe which project beyond the width of the normal connecting rod cross section, can be formed by correspondingly flattening a short end section of the starting material and provided with the fine toothing without impairing the usability of the clutch shoe is.
  • the material consolidation caused by the flattening ensures that the U-shaped coupling shoe, even with a reduced wall thickness compared to the normal connecting rod cross-section, receives a form strength that is several times higher than in the case of the bow-shaped from the flat material level the broad side of which is formed by webs.
  • a design that has proven particularly useful according to the invention is that the overall thickness of the rod section reduced in thickness corresponds to approximately twice the profile height of the fine toothing and the profile height of the fine toothing is approximately equal to one third of the thickness of the normal rod cross-section is.
  • the stretched width of the rod section reduced in thickness is dimensioned at least approximately twice as large as the thickness of the normal rod cross-section.
  • the two legs of the coupling shoe which is U-shaped in cross section, can be raised by an amount over the broad side of the linkage which corresponds approximately to its normal cross-sectional thickness.
  • An adjacent linkage which can be brought into engagement with the coupling shoe and which is provided with fine teeth on its narrow sides is therefore encompassed by the coupling shoe over its entire cross-sectional height.
  • Another design feature of the linkage coupling according to the invention also lies in the fact that the profile of the fine toothing is at least partially flattened in the web section of the coupling shoe that is parallel to the normal linkage cross section, in order to correspondingly close the contact surface for the broad side of the adjacent linkage inserted into the coupling shoe enlarge.
  • a method according to the invention for producing a length-adjustable rod coupling is mainly characterized in that the tooth profile of the fine toothing is formed directly with the flattening of the drive rod cross section and then the two side wings of the flattened cross-sectional area are then raised from the rod plane.
  • the flattened rod cross-section with its toothed side surface is cranked at least to the level of the broad side adjoining it of the normal rod cross-section.
  • the starting material is flattened corresponding to twice the length of a coupling shoe and provided with the toothing, and then a cut is made halfway along the toothing, either before the Side wings of the flattened linkage cross section can be raised in a U-shape, or after they have been raised previously.
  • a length-adjustable linkage coupling 1 with a first linkage forming a connecting rod 2 is shown.
  • the drive rod 2 has at its free end an approximately U-shaped, upwardly open coupling shoe 3, which is provided on the inside of at least one, but preferably both legs 4 with fine teeth 5, the tooth profiles of which are essentially transverse to the longitudinal direction the drive rod 2 extend.
  • a second linkage for example also a drive rod 6, consists of flat material with a rectangular cross section and is provided with fine teeth 7 on at least one, but preferably on both narrow sides, which is complementary to fine teeth 5.
  • the drive rod 6 can be positively inserted from above into the fine toothing 5 of the U-shaped coupling shoe 3 on the drive rod 2 at any point of its length range provided with the fine toothing 7. Since here the drive rod 6 is encompassed on its narrow sides by the two legs 4 of the clutch shoe 3, the transverse forces which occur when the drive rods 2 and 6 are moved longitudinally together can be safely absorbed by the clutch shoe 3 without the clutch connection being able to disengage.
  • the coupling shoe 3 which is U-shaped in cross section, is made of the same material from which the drive rod 2 is made, namely of a strip of steel strip. It is important to manufacture the connecting rod 2 and the coupling shoe 3 in one piece, the bottom or web 8 of the coupling shoe 3 being at least at the same level as the upper broad side of the connecting rod 2.
  • the drive rod 2 is manufactured together with the clutch shoe 3 as a stamped and bent part, the clutch shoe 3 as a whole, that is to say with its two legs 4, the base or web 8 and the fine teeth 5 being produced by an embossing press process.
  • the embossing process is carried out on a predetermined length section 11 of a strip steel strip 12 or the like which forms the starting material and has the same width 13 over its entire length, which corresponds to the cross-sectional width of the drive rod 2.
  • the strip steel strip 12 on the length section 11 is reduced in its cross-sectional thickness so that it assumes a cross-sectional width 14 that is approximately twice as much can be dimensioned large, such as the starting width 13 of the strip of strip material 12.
  • the tooth gaps 15 of the fine teeth 5 in the form of recessed press marks are simultaneously incorporated into the reduced material thickness of the length section 11, in such a way that the top surfaces of the teeth 16 formed between two successive tooth gaps 15 are in the plane of the tooth Cross-sectional thickness reduced length section 11 remain.
  • the tooth gaps 15 formed by the embossing process extend over the entire width 14 of the reduced length section 11, as can be clearly seen in FIG. 5.
  • the side wings 18 of the length section 11 projecting on both sides by the dimension 17 over the normal cross-sectional width 13 of the steel strip strip 12 are raised at least approximately 90 ° from the normal cross-sectional plane, so that thereby the two legs 4 of the coupling shoe 3 arise with the fine toothing 5 lying on its inside, as can be seen in FIG. 6.
  • the raising of the side wings 18 is expediently such that the outer surfaces of the two legs 4 of the coupling shoe 3 come to lie at least approximately in the same alignment with the narrow sides 19 of the steel strip 12 or the drive rod 2.
  • a bending die For the raising of the side wings 18 to the legs 4 of the clutch shoe 3, a bending die can be used which is essentially flat on its end face, but has profiles on its longitudinal side faces which correspond to the tooth gaps 15 and the teeth 16.
  • their fine serrations 5 on the inside maintain their exact transverse alignment with the longitudinal axis de drive rod during the bending deformation.
  • the areas of the teeth 16 remaining in the area of the bottom or web 8 of the clutch shoe 3 are at least partially flattened, so that their head surfaces widen compared to the head surfaces of the fine teeth 5, while the tooth gaps 15 narrow there accordingly (FIG. 3) .
  • the bending tool which causes the side wings 18 to rise to the legs 4 of the coupling shoe 3 can be designed such that it bends the bottom or web 8 of the coupling shoe 3 so far upwards relative to the lower broad side of the strip of strip material 12 or the drive rod 2, that the inner surface of the bottom or web 8 reaches at least on the same level with the upper broad side of the strip of strip material 12 or the drive rod 2.
  • the length section 11 flattened and widened by the embossing process is dimensioned there in such a way that it enables the simultaneous formation of two coupling shoes 3 with adjoining drive rods 2, if care is taken to ensure that notches 18 in the side wings are halfway along the length section 11 20 lie in the area of which the raised legs 4 of the clutch shoes 3 are interrupted.
  • a separating knife 21 can then be effective in this area, as is indicated in FIG. 7. After the cutting stroke of the same, two connecting rods 2, each with a coupling shoe 3 in a mirror-inverted position, are completed.
  • FIGS. 2 to 4 of the drawing each on an enlarged scale. It can be seen in particular that the total thickness 9 of the legs 4 and the bottom or web 8 on the coupling shoe 3 corresponds to approximately two thirds of the material thickness 10 of the drive rod 2. Furthermore, it is clear, particularly from FIGS. 2 and 4, that the tooth gaps 15 of the fine teeth 5 have a depth and consequently the teeth 16 thereof have a height which corresponds to approximately half the total thickness 9 of the legs 4 of the coupling shoe 3.
  • Fig. 3 is finally also indicated that by flattening the teeth 16 on the bottom or web 8 of the clutch shoe 3, the top surfaces of which form an enlarged support pad for the drive rod 6 to be engaged by a narrowing of the tooth gaps 15 present between the teeth 16 is.
  • relatively short rods in particular drive rods 2
  • they can also be provided with strips of strip material transverse to their longitudinal direction with their normal cross-sectional width before the embossing process is carried out on them.
  • the punch presses used to manufacture these short rods or drive rods can then work with large numbers of strokes and thereby enable inexpensive mass production.
