Definitions

  • the present invention relates to a curtain closure with profiled bars, each of which is pivotally connected to one another by a hinge about a pivot axis and can be transferred from an extended position in which the profiled bars are arranged essentially along a straight line to a curved position in which the Profile bars are arranged along a curved line, and the profile bars each have a first support section, on which a first cover surface is arranged, and a second support section, on which a second cover surface is arranged, which is movable relative to the first cover surface, the first and the second covering surfaces of the two adjacent profiled bars face each other and overlap each other in the radial as well as in the curved position of the profiled bars spaced from the pivot axis in the radial direction about the pivot axis.
  • Such curtain closures are e.g. known from EP 0 635 619. They are used to lock the compartments of cupboards and the like. For this purpose, the curtain closure is guided in rails, the compartment being closed when the profiled bars are in the extended position. Then the parts of adjacent profile bars facing the outside of the compartment lie against one another. To open the compartments, the curtain closures are moved along the rails in a known manner, the profile bars being transferred into the curved position for the purpose of rolling up. In many cupboards, the curtain locks are not rolled up, but they are led into the cupboard in an arc.
  • the facing cover surfaces which are arranged on the two support sections, protect the hinges that connect the individual profile bars to each other.
  • the cover elements prevent the hinges from being exposed from the outside and e.g. can be damaged or destroyed by vandalism.
  • the hinges are designed as soft hinges, there is a risk of destruction with exposed soft hinges. Due to the cover surfaces, access to the hinge is not possible, regardless of whether the profile bars are in the extended or a curved position.
  • the profile bars of the curtain lock Due to the construction of the profile bars of the curtain lock, the cabinet builder is hampered in the design of the cabinets.
  • the profile bars can either be arranged only in the extended position, that is to say along a straight line, or can be pivoted in the predetermined pivoting direction, for example for the purpose of rolling up.
  • the object of the invention is therefore to overcome the disadvantages of the prior art and to provide a curtain closure which can be used more universally and yet ensures reliable protection of the hinge.
  • a curtain closure of the type mentioned in which, in the extended position, both the first support section and the second support section are spaced apart in the pivoting direction about the pivot axis from the respective adjacent profile bar, so that the profile bars are in a second curved position can be transferred, in which the profiled bars are arranged along a second line which is curved opposite to the first curved line, the cover surfaces overlapping one another.
  • the first support section can be designed as a projection and the first cover surface can be arranged on the side of the first support section facing away from the pivot axis
  • the second support section can be designed as a recess and the second cover surface on which the sc
  • the axis of the second support section facing the axis may be arranged, the projection engaging in the recess.
  • the first and / or second covering surface viewed in cross-section of the profile bar, can at least approximately form a circular arc. In this way, a particularly narrow gap between the two cover surfaces can be realized over the entire pivoting range of the profile bars.
  • first and / or second cover surfaces touch one another at least in one of the curved positions or the extended position. This allows sealing by the curtain closure.
  • the profile bars viewed in cross section, can be essentially rectangular, with two narrow sides lying opposite one another, the projections and recesses being arranged on the narrow sides. This enables particularly flat curtain closures to be realized.
  • the profile bars are essentially trapezoidal, with a wider outside and a narrower inside, which are each connected to one another by longitudinal sides. This trapezoidal design enables particularly tight roll-up radii to be achieved.
  • the recesses and the projections can be arranged on the long sides of the trapezoidal profile bars.
  • pivot axis is arranged closer to the inside than to the outside.
  • the hinges can be formed by soft hinges. This also reduces the noise when using the curtain locks.
  • the hinge can be formed by a rigid hinge. With such a hinge, close tolerances can be maintained.
  • the curtain closure can also be made more stable. Fixed hinges also allow a more precise definition of the swivel axis than is possible with soft hinges.
  • the profile bars can be releasably connected to one another.
  • Such detachable connections between individual profile bars can be realized both with soft hinges and with fixed hinges.
  • the hinge is mounted at a distance from the inside to the outside from the long side. This allows the hinge to be moved out of the sliding area to reduce wear.
  • a stop device can be provided which limits the pivoting angle between the profile bars in the second curved position. This allows the swivel angle to be precisely defined and overloading of the hinge can be avoided.
  • the stop device is formed by the first or second support section and a support surface arranged on the respectively adjacent profile bar, the first or second support sections for limiting the swivel angle in the second curved position with the support surface in the swivel direction around the swivel axis is plantable. In this way, a simple, inexpensive and effective anchor device can be realized.
  • At least one rail can be provided, along which the profile bars of the curtain fastener can be guided, whereby adjacent profile bars on the rail can be guided from the extended to one of the curved positions.

  • the hinge 6 is thus a rigid hinge with a precisely defined pivot axis 7.
  • Both the holding section 8, the receiving section 9 and the web 10 are integrally formed with the respective longitudinal sides 5 and are therefore made of the same material as the entire profile bar 2. This material can be various suitable plastics.
  • the profile bar 2 has on the long sides 5 in each case a first support section 12 on one long side and a second support section 13 on the opposite long side.

  • the distance between the two adjacent cover surfaces can be very narrow in order to prevent the ingress of dirt. Since the cover surfaces do not touch, pivoting is not hindered.
  • a stop device 16 is provided, which is formed by the first support section 12 designed as a projection and the web 10. By pivoting the two adjacent profile bars 2 into one another, the first support section 12 can be brought into abutment against the web 10, which thus forms a support surface.
  • a second stop device is formed by the web 10 and the opening 11 in the receiving section 9. By pivoting the profile bars 2 against one another, the web 10 can be brought into contact with the opening 11 in the receiving section 9.
  • the curtain closure 1 is formed by a plurality of profile bars 2, which are nested in the manner shown in Fig. 1.
