Definitions

  • the invention relates to a holding band for holding lamellae of a blind and a method for producing a retaining band according to the features of patent claims 1 and 10.
  • Roller blinds and venetian blinds include a curtain with slats that can be attached to straps such as steel straps and / or straps. It is known to rivet front end of the slats excellent, pin or bolt by means of two tubular rivets on the respective tape and assemble and caulk. In the same way can be secured in recesses along the longitudinal edges of the slats engaging claws, rings or eyelets with the respective drawstring.
  • This type of connection has the disadvantage that cracks or breakages in the bands can occur during winding and unwinding of the retaining bands or when these bands are revolved around rollers or deflection wheels, and / or that such connections can become loose.
  • the preparation of such compounds is relatively complicated and expensive.
  • the holding means are secured against rotation by means of only one rivet each on the metal strip.
  • limited holes are formed on the band by means of a cutting punching tool of protruding teeth.
  • the teeth wedged with a square recess on the retaining means.
  • the band is reinforced in the region of the joints by beads or embossing. Due to the improved distribution of force during the rolling of the tape, the risk of the formation of a break point is reduced.
  • FIG. 1 shows in an exploded view parts of a tether 1 for holding lamellae 2 ( FIG. 7 ) of a curtain in the area of a holding means or holding part 5 to be fastened to a metal strip 3 with a rivet 7.
  • Such holding strips 1 can be designed for different functions in rollable or rollable lamellae hangings, eg as a carrying, pulling, lifting or turning tape ,
  • a curtain can comprise a plurality of holding straps 1 with different functions.
  • the metal strip 3 comprises two or more crosswise or star-like arranged cuts 9.
  • These cuts 9 delimit teeth or prongs 11, which advance when the rivet 7 is pressed in or alternatively
  • a special punch-cutting tool (not shown) are transformed or folded so that they protrude from the defined by the metal strip 3 band level.
  • the rivet 7 could also be designed such that it first punches the cuts 9 during the pressing in and subsequently transforms the serrations 11 formed thereby.
  • To stabilize the tether 1 or for distributing the forces acting on the metal strip 3 during bending of the tether 1 or bending stress in the region of the joints and / or to prevent cracking are preferably in the metal strip 3 square or rectangular beads 13 or coins with parallel and orthogonal to the longitudinal edges of the metal strip 3 aligned boundaries and with a structure depth s ( Fig.
  • the holding parts 5 comprise a main body 15 and a laterally protruding on the main body 15 bolts 17 or retaining pin for pivotally securing a blade 2 (FIGS. FIG. 7 ).
  • bolts 17 or retaining pin for pivotally securing a blade 2 (FIGS. FIG. 7 ).
  • flange-like widenings or stops 17a can be formed on one or both sides of a connection zone. These prevent the movement of a part, which is held pivotably on the pin 17 in the region of the connection zone, in the direction of the pin axis.
  • the holding part 5 instead a bolt 17 also comprise a bearing or a bolt receptacle for the pivotable holding of a lug 2 projecting pin.
  • a hole or a continuous recess 19 is excluded with alternating cross section.
  • the cross section is round.
  • FIG. 2 shows the part arrangement of the exploded view FIG. 1 from a different angle, namely seen obliquely from behind.
  • the recess 19 has a non-rotational or cylindrically symmetrical cross-section.
  • the base body 15 and the bolt 17 are formed as a one-piece die-cast with a continuous recess 19.
  • the recess 19 could also be formed on one side or not continuously or cup-like with at least partially square cross-section on the side facing the metal strip 3 side of the base body 15, wherein the cross-section widening outwardly dome-like.
  • the holding part 5 may also be formed completely or partially as a plastic part.
  • FIG. 3 shows a longitudinal section of the parts arrangements in the Figures 1 and 2 , wherein the cutting plane is orthogonal to the metal strip and runs parallel to the longitudinal edges of the metal strip 3.
  • FIG. 4 shows another, manufactured as a die-cast part holding part 5, whose width b1 corresponds to the width of the associated metal strip 3.
  • a non-continuous further recess 19a is embedded in the base body 15 on the band side.
  • the holding part 5 is connected against rotation with the metal strip 3.
  • the prongs 11 of the metal strip 3 have been reshaped so that they now fit positively in the region of the inner edges of the angular portion of the recess 19 and are pressed by the rivet to the inner sides of the recess 19.
  • FIG. 5 and 6 show a front view and a side view of a finished tether first
  • the inventive retaining straps 1 can be prefabricated with a high degree of automation simple and inexpensive.
  • the slats 2 of a blind are subsequently connected by means to be attached to the slats 2 connecting parts 23, pivotally connected to the holding parts 5.
  • FIG. 7 shows a detail of such a curtain, wherein the slats 2 are pivotally connected to a carrier tape 25 and a drawstring 27.
