Definitions

  • the invention 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, the connecting hook carrying a circular or semicircular joint element on a spacer web and the joint chamber being a circular receptacle with an opening directed outwards.
  • Profile bars for roller shutter curtains are known in multiple embodiments.
  • 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 arranged at a short distance from one another. 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.
  • a profile rod for a roller shutter curtain is known, in which the connecting hook carries a circular or semicircular joint element on a spacer web and the joint chamber is a circular receptacle with an opening facing outwards.
  • roller shutter profile bars are designed in a similar manner.
  • connection hook is guided in the articulation chamber only along a contact line, or that this guide has a circular circumferential contact.
  • extreme stress can lead to the breakage of the guide hook in the joint chamber and thus to the destruction of the entire joint mechanism.
  • the large contact surface of the guide can lead to jamming of the guide elements.
  • the hinge element carries at its opposite free ends outwardly projecting angular webs, and that angular webs are formed on the free ends of the outward opening of the articulation chamber towards the center of the opening, which have the angular webs in their outer dimensions and in their angular position correspond to the joint element.
  • a jamming of the connecting hook within the joint chamber is also excluded.
  • the advantage of the embodiment according to the invention compared to the existing systems can be further supported in 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 system, 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 invention 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 original profile.
  • the profile bar of the invention can be made of polymeric material, but it can equally well be a profile rolled out of metal.
  • 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 bar which is 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.
  • 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 141, 144 directed inward toward the center of the joint chamber 4 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 to the outside in the outer wall region 161 to the end wall 13 and in the outer wall region 162 to the end wall 14.
  • profile bar 1 The function of the profile bar 1 according to the invention is described with reference to the illustration in FIG. 2. 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.
  • 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 angled webs 33, 34 of the joint element 3 lie against the associated inner wall region 14 of the joint chamber 4 in a linear manner.
  • 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 the 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 line shape.
  • connection between the profiled bars 1 ′ and 1 ′′ shows the free ends of the angled webs 33, 34, 143, 144 in the opposite engagement position.
  • the angled web 143 has now entered the receiving chamber 35 and is located there with its outer wall regions on the outer wall regions of the end wall 13
  • 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 ".
