Definitions

  • the innovation relates to a profile bar for roller shutter curtains with a connecting hook at one free end and a joint chamber at the opposite free end.
  • DE-AS 2 111 317 describes a roller shutter hollow profile rod made of extruded plastic which, in cross section, consists of at least one self-contained chamber with two main walls curved in the same direction and spaced apart from each other. The centers of curvature lie on the side facing the roller shutter roller.
  • the main walls are connected to one another by connecting webs, one of the connecting webs having a hook bent toward the roller shutter roller, while an articulated chamber provided with a suspension slot for the supporting web of the adjacent profile bar is formed on the other connecting web.
  • connection hook is guided in the joint chamber only along a contact line. This can lead to breakage of the guide hook in the joint chamber and thus destruction of the entire joint mechanism under extreme loads. This is where the innovation comes in, which has set itself the task of optimizing the guidance of the connecting hook in the joint chamber in such a way that a break at the connection point is no longer to be feared even in the event of an overload.
  • the connecting hook carry a semicircular, outwardly open joint element on a spacer web, on the opposite free ends of which outwardly projecting angular webs are formed, and that the joint chamber is a circular receptacle with an outwardly directed opening, at the free ends of which Angular webs directed towards the center of the opening are formed, which correspond in their external dimensions and in their angular position to the angular webs of the joint element.
  • the exact center of the joint chamber serves as the fulcrum and that there is no longer any possibility of moving the connecting hook within the joint chamber.
  • This disadvantage of the existing systems can be further supported by the fact that the spacer web with the joint element is at a distance from the associated outer end face of the profiled rod which corresponds to the height of the angular webs at the free ends of the joint chamber.
  • the exposed partial areas of the joint chamber are additionally guided on the correspondingly designed outer sides of the end faces of the assigned profile rod when two adjacent profile rods are pivoted.
  • This guide can also be a linear contact, but it can also be over a more or less large area of the outer wall areas of the joint chamber on the one hand and the outer wall areas of the associated end face of the profile bar on the other hand.
  • the profile bar of the innovation is advantageously a hollow profile.
  • This hollow profile can be reinforced in its interior, for example, by ribbing, which are made in one piece with the hollow profile.
  • the profile bar of the innovation can consist of a polymer material, but it can also be a rolled metal profile.
  • the spacer web carrying the joint element can expediently be formed eccentrically on the base of a recess in the end wall of the profile bar. Such a measure can increase the rotational mobility of the profiled rods articulated in one another. This also applies to the fact that the joint chamber is also formed off-center in the opposite end wall of the profile bar.
  • Fig. 1 shows the profile bar 1 as a hollow profile with reinforcing webs 11, 12 in its interior.
  • the spacer web 2 is formed on the lower end face 13 and carries the joint element 3 which is open to the outside at its free end 21.
  • the hinge element 3 is semicircular and has at its free ends 31, 32 the outwardly projecting angular webs 33, 34.
  • the opposite end wall 14 of the profile bar 1 is formed as part of the joint chamber 4. At the free ends 141, 142, angular webs 143, 144 directed inward to the center of the joint chamber are formed.
  • the outer wall 15 of the profiled bar 1 is shown curved slightly outwards, while the inner wall 16 diverges from a base outwards into the outer wall region 161 to the end wall 13 and into the outer wall region 162 to the end wall 14.
  • profile bar 1 The function of the profile bar 1 according to the innovation is described with reference to the illustration in FIG.
  • profile bars 1 There are several profile bars 1 shown in an articulated connection with each other.
  • the profile bars shown are equipped with the connection features as have been described for FIG. 1.
  • the same features have been given the same names here.
  • Two profile bars 1 are shown here in an articulated connection with one another, the profile bars 1, 1 'being shown in a bent representation, while the profile bars 1', 1 ⁇ run in a straight line in one plane.
  • the joint element 3 is inserted into the joint chamber 4.
  • the free ends of the angular webs 33, 34 of the joint element 3 lie in a linear manner on the associated inner wall regions 14 of the joint chamber 4.
  • the free ends of the angular webs 143, 144 of the boundary wall 14 of the joint chamber 4 also lie linearly on the associated outer walls of the joint element 3 due to their corresponding dimensions to the angular webs 33, 34 of the joint element 3.
  • the web 2 between the outer surface of the end wall 13 and the outer surface of the joint element 3 has a height which corresponds to the length dimensions of the angular webs 143, 144 at the free ends 141, 142 of the end wall 14. This creates receiving chambers 35, 36.
  • the receiving chamber 35 is free in the connection form between the profile bars 1, 1 ', due to the bending of the profile bar 1 from the engagement of the angle bar 143.
  • the angular web 144 is inserted into the receiving chamber 36 and touches both the outer surface of the joint element 3 and the outer surface of the end wall 13 in a linear manner.
  • connection between the profile bars 1 'and 1 ⁇ shows the free ends of the angle bars 33, 34, 143, 144 in the opposite engagement position.
  • the angled web 143 has entered the receiving chamber 35 and, with its outer wall regions, is additionally in contact with the outer wall regions of the end wall 13 there.
  • the angular web 144 is pivoted out of the receiving chamber 36 and now lies against the angular web 33 of the joint element 3. In this way, there is a flush construction between the two profile bars 1 'and 1 ⁇ .
