  • a roller shutter has a roller curtain made of roller shutter slats connected to one another in an articulated manner, which are pivotably connected to one another about mutually parallel pivot axes which run in a longitudinal direction of the shutter slats.
  • the roller shutter slats are also referred to as “slats” or “roller shutter profiles” and are typically made of plastic or aluminum, previously also made of wood.
  • the roller curtain can be wound onto a roller shutter shaft and its roller shutter slats are slidably guided in lateral guide rails when it is unwound from the roller shutter shaft.
  • the European patent application EP 0 731 247 A2 discloses a roller shutter, the first roller shutter slats of which can be pushed into one another to a certain extent in order to protect them from being pushed open and which, when pushed into one another, are held against one another against pivoting.
  • a first of the first roller shutter slats is articulated to a roller shutter shaft and a last one of the first roller shutter slats is articulated to a first further roller shutter slat, the further roller shutter slats being articulated to one another as in conventional roller curtains.
  • the first roller shutter slats slide into one another at the end of the unwinding so that they are held against each other against pivoting and thereby prevent the roller curtain from sliding open when the roller shutter shaft is held in a rotationally fixed manner.
  • the object of the invention is to propose an articulated connection for connecting a roller shutter of a roller shutter to a roller shutter shaft, with which a roller shutter of the roller shutter can be wound onto the roller shutter shaft and which protects against sliding of the closed or lowered roller shutter.
  • Another object of the invention is to propose a roller shutter with such an arrangement.
  • the arrangement according to the invention has a push link chain and a connecting link.
  • the push link chain is used for an articulated connection of the connecting link with a roller shutter shaft and the connecting link is used for an articulated connection of a roller curtain with the push link chain, so that the roller curtain can be wound onto the roller shutter shaft, the push link chain and the connecting link in front of the roller curtain or as the innermost layer between the roller curtain and the roller shutter shaft are wound onto the roller shutter shaft.
  • a "push link chain” is a chain that can transmit a tensile and compressive force.
  • a first chain link of the push link chain can be connected to the roller shutter shaft in an articulated manner about a first pivot axis, the first pivot axis running parallel to an axis of rotation of the roller shutter shaft.
  • first chain link here denotes that which can be or will be connected in an articulated manner to the roller shutter shaft and which is preferably an end link of the push link chain.
  • the chain links of the push link chain are connected to one another such that they can be pivoted about mutually parallel pivot axes which run parallel to the first pivot axis.
  • the chain links of the push link chain are designed in such a way that they support one another or slide into one another when the push link chain is subjected to compressive stress, so that their pivoting angles are limited to one another in one direction and the push link chain does not buckle in at least one direction.
  • a last chain link of the push link chain is pivotably connected to the connecting link about a second pivot axis which runs parallel to the first pivot axis and to the pivot axes of the chain links of the push link chain.
  • the “last chain link” here refers to the chain link which is connected in an articulated manner to the connecting link. It is preferably also an end link of the push link chain.
  • the connecting member has a hook-shaped connecting device, seen parallel to the pivot axes, to a connection to a first pivotable about a third pivot axis which runs parallel to the other pivot axes Roller shutter slat on the roller curtain.
  • the “first roller shutter bar” is the term used here for the roller shutter bar of the roller curtain, which is provided or used for the articulated connection to the connecting member.
  • a roller shutter slat is used at one end of the roller curtain.
  • the hook-shaped connecting device of the connecting member is designed in such a way that it can be hinged or inserted into a hook-shaped connecting profile of the first roller shutter slat.
  • the hook-shaped connection profile is used for an articulated connection of the roller shutter slats to one another, the hook-shaped connection profile of the first roller shutter slat being used for the articulated connection with the connecting member of the arrangement according to the invention.
  • the invention provides a pivot stop for the first roller shutter slat, which limits a pivot angle of the first roller shutter slat to the connecting member in a pivoting direction, or by which the pivot angle can be limited, so that when pressure is applied, the first roller shutter slat rests against the pivot stop and thereby further pivoting or prevents buckling.
  • the unwound or lowered roller curtain is prevented from being pushed on, or at least made more difficult if the roller shutter shaft is held in a rotationally fixed manner.
  • the pivot stop is located on a side of the third pivot axis facing away from the second pivot axis, it can be located on an imaginary plane containing the two pivot axes on a side of the third pivot axis facing away from the second pivot axis, or it can be laterally offset from the imaginary plane.
  • the chain links of the push link chain and the connecting link are preferably designed so that they, including the first roller shutter slat, form an arc when subjected to compressive stress, the curvature of which is limited by the limitation of the pivoting angle of the chain links, the connecting link and the first roller shutter slat to one another.
  • the pivot stop is preferably arranged on an inside of the connecting member facing the roller shutter shaft so that the said curvature is limited.
  • the inside is the side of the connecting link that is on the inside when the roller shutter is rolled up.
  • the pivot stop is rigid with respect to the second and third pivot axis.
  • the connecting device thus has, for example, no spring member between the elements forming the pivot axes and the pivot stop.
  • the pivot stop extends at least 10 millimeters, in particular at least 20 mm and preferably at least 30 mm, from the third pivot axis on the side of the third pivot axis facing away from the second pivot axis.

  • the pivot stop preferably extends over at least a quarter, in particular over at least a third and preferably over at least half of the first roller shutter slat from the third pivot axis on the side of the third pivot axis facing away from the second pivot axis.
  • This extension enables leverage that limits local forces. In particular, overloading of the first roller shutter slat in the area of the hook-shaped connecting device and in the area of contact with the pivot stop can be avoided.
  • One embodiment of the invention provides a cranked swivel stop, that is to say a swivel stop angled twice in opposite directions.
  • the connecting member together with the pivot stop can have the shape of a Z with a short web that is approximately rectangular to the flanges of the Z, whereby the flanges of the Z do not have to be parallel to one another.

  • a roller curtain which is articulated in the manner explained above with the arrangement according to the invention with a roller shutter shaft, so that it can be wound onto the roller shutter shaft and unwound from it.
  • the push link chain and the connecting link prevent the roller curtain from sliding open, thanks to the ability to transmit a thrust force and the pivot angle limits between the chain links, the connecting link and the first roller shutter slat, which prevent buckling in at least one direction.
  • the in Figure 1 The partially illustrated roller shutter 1 according to the invention has an octagonal tube as a roller shutter shaft 2, a push link chain 3, a connecting link 4 and a roller curtain 5 with roller shutter slats 6, of which a first roller shutter slat 6a is connected to the connecting member 4.
  • the first roller shutter slat 6a like the other roller shutter slats 6, has hook-shaped, complementary connecting profiles 14 on its upper and lower edge in an end view, with which the roller shutter slats 6 are pushed into one another in a longitudinal direction of the roller shutter slats 6, whereby the roller shutter slats 6 are articulated around mutually parallel and pivot axes extending in the longitudinal direction of the roller shutter slats 6 are pivotably connected to one another.
  • the pivot axes of the roller shutter slats 6 run parallel to an axis of rotation of the roller shutter shaft 2, which is a longitudinal axis of the octagonal tube that forms the roller shutter shaft 2.
