Definitions

  • the present invention relates to a folding shutter, comprising:
  • folding shutters are already known in great variety. They are used, for example, as a sunshutter or as protection against rain or to close off an opening, for example by way of protection against burglary, etc.
  • the shutter parts of such folding shutters can be constructed in many different ways and may, for example, be configured as solid, hollow or perforated panels, or as having slats which are arranged virtually parallel to one another, etc.
  • folding shutters comprise two shutter parts (a basic shutter part and one shutter extension part).
  • these folding shutters may also comprise more than two shutter parts which are connected to one another in a concertina-like manner.
  • a large number of possible drive means for moving the shutter parts between the fully open position and the closed position of the folding shutter are also already known.
  • the movement may in this case be driven by hand or by a motor.
  • drive means are known which make use of a pulling cable or chain drive or belt drive, etc.
  • These shutter parts usually comprise locks which have to be operated manually.
  • the known locking means which ensure automatic locking of the folding shutter when this folding shutter is moved into its closed position have various drawbacks.
  • the known electric locks have the drawback that if the electricity fails either the folding shutter cannot be locked or the folding shutter remains locked in its closed position and can no longer be opened.
  • US 2010/0282418 A1 discloses a folding shutter according to the introduction of the first claim.
  • various locking means for such a folding shutter are described.
  • these locking means in each case comprise pivoting components.
  • these pivoting components become soiled or oxidized, there is a significant risk that these components will be in the wrong position at the wrong point in time, in which case the folding shutter no longer opens or closes correctly.
  • the construction of these locking means is in each case relatively complicated and comprises a relatively large number of movable components.
  • the locking means of a folding shutter according to the present invention on one side of the folding shutter or centrally on the folding shutter, between the two lateral sides thereof. It is also possible to provide more locking means and to provide locking means, for example on both lateral sides of the folding shutter, in order to achieve a particularly strong lock.
  • the first locking means comprise a locking hook and the second locking means comprise a locking pin which engages in the locking hook when the folding shutter is moved to the closed position.
  • the locking hook may in this case comprise a hook-shaped slot having an entry opening and a locking opening, in which the locking pin, when it engages in the locking hook, is taken from the entry opening to the locking opening via the hook-shaped slot and in which the entry opening is designed to be wider than the diameter of the locking pin and the dimensions of the locking opening virtually correspond to the diameter of the locking pin.
  • the folding shutter comprises counteracting means which exert a counterforce on the actuator rod, counter to the force with which the drive means engage on the actuator rod when moving the folding shutter into its closed position, so that the locking means engage with each other on account of this counterforce when the folding shutter is moved into its closed position.
  • the counteracting means of such an embodiment comprise a spring, in which the spring force of said spring forms part of the counterforce.
  • the actuator rod forms part of the counteracting means, in which case the force of gravity on said actuator rod forms part of the counterforce.
  • the actuator rod will in each case form part of a folding shutter according to the invention, in which the shutter extension part undergoes an up and down movement in order to open and close the folding shutter.
  • Said rotation shafts of such a particular embodiment preferably extend virtually horizontally in the fitted position of the folding shutter.
  • the basic shutter part and the shutter extension part are then preferably virtually in line with one another, one below the other.
  • the shutter parts In the open position of such a folding shutter, the shutter parts then preferably form a kind of awning with respect to the immovable part.
  • the total counterforce is preferably chosen as a compromise between a counterforce which is sufficiently large to be able to keep the folding shutter in its closed position in a secure way and a counterforce which is sufficiently small to be able to release the locking means in a simple manner in order to be able to easily open the folding shutter.
  • the drive means of a folding shutter according to the present invention may, more specifically, comprise a pulling cable and a disc, in which one end of the pulling cable is connected to the actuator rod and the other end is connected to the disc and said pulling cable can be rolled onto said disc.
  • the disc is preferably arranged in the vicinity of the fixed rotation shaft.
  • Such drive means with a pulling cable are particularly suitable for folding shutters which can be moved between a kind of awning and a screen which extends virtually parallel to the wall (when the folding shutter is attached to a wall).
  • the pulling cable is then rolled onto the disc.
  • the shutter extension part can be lowered under the effect of the force of gravity, with the pulling cable exerting a smaller counteracting force and thus guiding the movement.
  • the drive means preferably comprise a closed continuous cable or chain or belt, etc. so that the same pulling means can be used both for opening and for closing the folding shutter since, in this case, the force of gravity can no longer be used for opening the folding shutter.
  • the drive means comprise a toothed belt, in which the actuator rod is connected to the toothed belt in order to connect the latter to the drive means.
  • the drive means of a folding shutter according to the present invention can engage with the shutter extension part either by means of this actuator rod, or in a particular embodiment, for example, by means of an entrainment element and an entrainment pin.
  • the shutter extension part is connected to the actuator rod by means of such an entrainment element and such an entrainment pin, with the entrainment element being fixedly connected to the shutter extension part and being provided with an entrainment slot in which the entrainment pin is received and with the entrainment pin being fixedly connected to the actuator rod.
  • the second locking means and the drive means of a folding shutter according to the present invention are preferably connected to said actuator rod virtually at the location of the two opposite ends of the actuator rod.
  • the drive means are preferably connected to the actuator rod in the vicinity of the displaceable rotation shaft.
  • the shutter extension part to which the actuator rod is connected is preferably pivotably attached to the basic shutter part, so that the basic shutter part and said shutter extension part are rotatable with respect to one another about a hinging rotation shaft.
  • the second locking means are in this case connected to the actuator rod, preferably in the vicinity of the hinging rotation shaft.
  • the folding shutter is centrally locked between the fixed rotation shaft and the displaceable rotation shaft.
  • centrally locking the folding shutter in its closed position has the advantage that flapping of the folding shutter on account of, for example, the wind can be reduced significantly.
  • centrally locking the folding shutter has the advantage that a large distance is available for the locking means to engage with each other, as a result of which a secure locking can be achieved in a smooth manner.

  • guide means preferably comprise a guide profile which forms part of the immovable part.

  • the spring force will be an additional force which provides additional security that the locking pin (10) is kept in the locking hook (9) in order to lock the folding shutter.
