Definitions

  • the invention relates to a holder for slats, in particular slats for sun protection and daylight steering systems.
  • the slats of such systems are arranged in many of these systems between two panes or in front of or behind the window pane.
  • the slats can be attached in different ways to the window frame, to a carrier element or to the insulating glass spacer. They can run at an angle or, for example, sit in a C-profile fastened to the window frame or support element, be suspended from a profile ( DE 34 32 113 A1 ) or be connected to a carrier element, for example by gluing or welding ( DE 40 01471 A1 ). It is also common to slidably store the lamellae arranged in the space between the panes by holding them in oblong holes, so that the lamellas can expand or contract according to the temperature development. A disadvantage of this type of holder is that the lamellae tend due to their movement permitting game of the holder to occupy an undefined position in this. It can come as a result to a rattling of the slats.
  • the EP 0 558 154 A2 relates to a drawstrike operated blind.
  • a sealing member 170 disposed in a frame structure 5 is shown with engaging pieces 172 pressurized on the outside by a spring 173.
  • the sealing element 170 is provided with a side edge of the fabric web 1 by means of a sliding element 174 engaged.
  • the invention has for its object to provide a holder for slats of sun protection and daylight steering systems, which is adapted to the temperature-induced changes in length of the slats and ensures a defined position of the slats.
  • An inventive holder for one or more elongated elements ie slats for sun protection and daylight steering systems, thus comprising an elastic or spring compensation unit, comprising two opposing and mutually engaging, relative to each other in the longitudinal direction of the elongated elements slidably disposed profiles, the one form common interior, in which a spring element is received.
  • the spring element is compressed when temperature-induced expansion of the elongated member and relaxes upon contracting of the elongated member in the longitudinal direction of the elongate member.
  • the spring element is held in the interior in the clamping or friction fit.
  • the spring element has a degree of freedom of movement, because as a result of the displaceability of the profiles a compensating movement of the spring element in the longitudinal direction is possible.
  • the common interior of the compensation unit is limited by transverse with respect to the longitudinal direction of the elongated elements web portions and in each case a longitudinally extending legs of the slidably disposed profiles of the compensation unit.
  • the web parts are provided as a stop for the legs.
  • the compensation unit comprises on the interior, opposite the elongate elements facing side another profile for receiving the elongated elements and on the opposite side of the first profile still another profile as a spacer to a window frame or support member or for receiving one or more further elongated elements ,
  • the further profiles are each integrally formed with the corresponding displaceably arranged profiles of the compensation unit, wherein they each have a common web part with them.
  • the outside of a leg of the profiles of the compensation unit is connected to the outside of an in Seen transverse to the elongate elements, located on the same web side leg of the relevant further profile substantially in alignment.
  • the respective other leg of the profiles of the compensation unit is not aligned with the legs located on the same side of the bridge, but arranged offset in relation to the longitudinal axis in the profile inside and outside each other concerned by the other leg further profile.
  • the components each consisting of a profile of the compensation unit and a further profile with common crosspiece, identical.
  • an elastic, floating support for the elongate element (s) is provided.
  • the bracket is suitable for slats or slat hangings in the space between panes of insulating glass, which are used for sun protection and daylight control. It is then supported in the horizontal direction on the disc spacer, which holds the two insulating glass panes in position. As seen in the vertical direction, it usually rests with the lower end on the disc spacer. The slats are always fixed in their position. If the holder is used as a connecting piece between two lamellae hangers, a secure arrangement of two or more lamellae hangings in the required length can be achieved. Due to the effect of the compensating element is an automatic, uniform length compensation.
  • the spring element by its friction or interference fit has a connection function, as will be explained below.
  • the spring element fixed due to its clamping or friction fit and the existing bias him laterally adjacent legs of the two sliding profiles of the compensation unit (compensation profiles), which limit the interior of the side. In this way, it is prevented that the compensation profiles forming the interior move apart.
  • the other profiles with the compensation unit are at least partially integrated.
  • the common web part so each form a profile of the compensation unit and another profile a one-piece component.
  • the integrated profiles then represent H-profiles.
  • the spring element is then located between these two components.
  • the version with staggered and flush-fitting profile legs of the compensation unit leads to a smooth outer shape of the holder.
  • a flexible base element is located in the interior of the compensating element as a spring element, then this exerts a pressure in the longitudinal direction of the elongate element, such as the lamella (s), against the web of the first profile, which acts on the elongated element. At the same time it exerts a pressure in the transverse direction, thus towards the outer and inner pane.
  • standing in contact with the spring element inner leg of the two profiles of the compensation unit are connected by the spring element. A relative displacement of the two support members out of the pulley plane is reliably prevented in this way.
  • the components or support parts each consisting of a profile of the compensation unit and a further profile, are identical, it is only necessary to produce a component and to stockpile.
  • the mating of the components to form the holder is made by one of them is pivoted about an axis parallel to the profile legs and about an axis transverse thereto.
  • the holder is preferably made of metal, e.g. Aluminum, stainless steel.
  • metal e.g. Aluminum, stainless steel.
  • other materials e.g. Plastic or fiber composites having the required properties in terms of strength, expansion behavior, is possible.
  • this spacer is in slide bearing assembly on the window and is firmly against the outside of the moving part of the holder.
  • the plastic spacers e.g. Block profiles or pin elements (pins). Due to the slide bearing arrangement, the movable part of the holder can move under the action of the compensation unit together with the blade end or the blade ends in the longitudinal direction of the blade back and forth.
  • the spring element of the compensation unit may be a spring, for example a leaf spring. This can be preloaded.
  • a flexible body with the required elastic properties (spring characteristic) can be used, which is inserted into the interior of the compensation unit.
  • the material used is, for example, an elastomer. However, other plastic materials or materials having elastic properties may be used.
  • the holder according to the invention is suitable for holding only one, as well as a number of elongated elements. It is suitable for use with sunblinds, especially internal lamellas.
  • At least one of the further or further profile is a U-profile.
  • at least one of the slidably disposed profiles may be a U-profile.
  • Other profile shapes are possible. These result from the particular application, the installation conditions, privacy and aesthetic aspects, etc.
  • the holder according to the invention can be designed so that the profiles are provided on the outer sides with a surface design, in particular corrugation, or a similar structuring for optical or aesthetic reasons.
  • the aligned outer sides of the legs are each provided at the ends with an angle or outer flange. Between the two angles or flanges is then the above-mentioned spacer, e.g. a block profile, and is so securely positioned.
  • spacer e.g. a block profile
  • angles or outer flanges of the aligned outer sides having legs of a profile of the compensation unit and the further profile are in an embodiment of the invention with the outside of the still further profile on the same side mounting substantially in alignment. In this way, the outer surface of the built-in bracket is continuous and it looks so appealing.
  • the sliding surface is recessed in the visible region of the compensation unit. This can e.g. be provided by the formation of a recess in the respective counter-profile, so that in the region of the return, the two profiles do not slide together and there eliminates a material stress with resulting wear marks.
  • the elongate element is preferably fastened to the holder, for example glued into the receiving profile. In this way it is ensured that the temperature or Expansion-contraction-related movement in the longitudinal direction in the compensation unit plays.
