Definitions

  • the invention relates to a connection arrangement for a slats having Venetian blinds or the like, the building side and fixed fixable support profiles and a fixed thereto top rail which is open on the side facing away from the support profiles and has a support profiles facing central base leg and two spaced lateral legs ,
  • the support profiles are defined by the building with conventional fasteners, for example on a lintel.
  • the top rails are used.
  • Such upper rails are known in various designs and take on the elevator and control mechanism of an existing blinds venetian blinds, a blind or similar darkening or shading elements.
  • the control mechanism includes, among other things, the motors and, in the case of a manual adjustment, the transmissions.
  • the control and drive mechanism is mounted in the cavity of the U-shaped upper rail. This is done by mechanical fasteners, such as screws, rivets and the like. You can, however, also by clamping in the U-shaped cavity can be used, provided that the hollow rail is provided with corresponding webs which are located at the free ends of the lateral legs, so that the components inserted into the cavity can be supported and fixed non-positively.
  • the top rails are used either with the U-shaped opening upwards, based on the mounted position or down. If this opening is at the top, recesses are provided in the opposite bottom of the top rail for the implementation of the turning cords, the elevator belts and the guide cables. This extra effort in the production has the advantage that the drive elements are hidden from the bottom.
  • U1 From the DE 195 4544 U1 is known an upper rail, which is held by a clamping lid which is fixed to the substructure of the building and has two downwardly directed legs, whose free ends are formed like a ridge.
  • the corresponding upper rail which is mounted in this case with the opening up, has at its free ends of the parallel leg corresponding notches corresponding to the detent-shaped formations of the clamping cover.
  • the invention has for its object to design a connection assembly of the type described in more detail so that can be dispensed with fixing the upper rail to the support profiles on additional mechanical fasteners, and that the assembly is simplified, it being ensured that a shift of the outer blind and a release of the compound causing components is effectively prevented.
  • the upper rail is provided on the support profiles facing the edge regions with fastening elements, and that each support profile has at least one on one side at least one with the associated fastener positively and / or non-positively engageable locking elements.
  • the upper rail and the support profiles are now designed so that the locking elements of the support profiles with the associated fastening elements of the upper rail are positively and / or non-positively engaged. Due to the shape- and material-springing properties of the materials used, an elastic deformation, in particular of the latching elements of the support profiles, is achieved during assembly. As a result, the connection between the support profiles and the upper rail can be made with a certain force. A shift in the external blind, which leads to disruptions during operation, can now be ruled out.
  • the upper rail is provided for forming the fastening elements with respect to the lateral legs outwardly projecting fastening strips, which lie in the plane of the central base leg of the upper rail.
  • Each support profile is designed angularly in the basic contour and equipped on one side with a spring leg, which has a toward the central base leg and at least one inwardly directed spring tab.
  • This spring tab is formed for example by cuts or by punching, which is then angled relative to the spring leg and includes an acute angle to the spring leg.
  • each spring tab of a supporting profile is provided with at least one inwardly directed locking cam, which engages under the facing mounting bar of the upper rail.
  • each spring tab is provided with at least one locking cam. This makes it possible for the upper rail initially to be inserted into the supporting profile in such a way that the locking cam facing away from the middle base leg engages under the fastening strip of the upper rail. In this position, the upper rail can still align because an axial displacement is possible.
  • the upper rail is pressed in the direction of the central base leg of the support profile, so that the locking cam associated with the base leg engages under the fastening strip. In this position, then an axial displacement of the upper rail is no longer possible.
  • the second locking cam could also be formed by the free end portion of the spring tab, but this is preferably angled.
  • the other locking cam is also made by punching and bending the corresponding portion of the spring tab 10.
  • At least one further spring leg is provided on the middle base leg of the retaining profile above the locking cams of the spring tongue, which is also machined out of the middle base leg in the stamping bending process. This spring leg presses when inserted upper rail on the central web or on the mounting bar of the upper rail, so that a backlash-free connection is ensured.
  • each middle base leg of the support profile is equipped with two spring legs which extend transversely to the central longitudinal axis of the upper rail and which are provided in the end regions. For this purpose, in addition to the spring tabs punched or cuts are provided.
  • the upper rail is also held on the spring leg opposite region, it is provided that at least one holding web is provided in this region of the support profile, which engages under the associated mounting bar of the upper rail used.
  • This holding web can either be produced in the stamping bending process, so that it protrudes from the surface of the end region, but it could also be the end portion bent several times or arcuate
  • the locking cam In order to bring in a disassembly of the upper rail, the locking cam out of engagement with the associated mounting bar, it is provided that in the free end a punching is provided in the spring leg, so that a tool in the form of a screwdriver can be inserted through this punched hole, so that the locking cams can be pressed outside the fastening strip.
  • the spring tab is pressed in the direction of the spring leg.
  • the spring tab Since in particular during disassembly of the upper rail, the spring tab is deformed, it is provided that it is provided to maintain stability with stiffening beads.
  • the locking cam facing away from the middle leg of the upper rail need not be located laterally on the spring tongue, but it may also be formed by punching the central region of the spring tab. It is also particularly advantageous if the end region of the middle leg of the upper rail facing locking cam is toothed, as this additional security against displacement of Venetian blind is achieved in the axial direction.
  • the retaining web which engages under the holding leg opposite the spring leg, also need not be formed by punching and bending of the end portion of the retaining profile, but this retaining web can also lie in the central region of the end portion of the support profile.
  • the support profile can be set securely on the building, it is provided that a plurality of mounting recesses are provided in the central base leg, which can be optionally used depending on the circumstances and which lie between two stiffening beads.
  • each support profile is formed by repeated bending, so that at least a part of the central base leg is at a distance from the middle leg of the upper rail. Furthermore, it is envisaged that a pressure flap produced in the stamping bending process is provided on the spring tab, so that you can support the deformation of the spring tab for disassembly of the upper rail by detecting this pressure tab.
  • each upper rail made of aluminum in the extrusion process.
  • Each support profile is made by means of suitable tools in the punch bending process of steel.
  • the upper rail 1 of the connection arrangement shown in FIG. 1 has a U-shaped cross-section and consists of a central base leg 2 and two lateral legs 21, 22 standing at right angles thereto.
  • Two fastening strips 3, 4 extend outward relative to these lateral legs 21, 22 that lie in the plane of the middle base leg 2.
  • the free ends of the lateral legs 21, 22 are arcuately deformed, so that support webs 23, 24 arise on which drive parts can be supported.
  • the fastening strips 3, 4 are located are in the stable area of the upper rail 1 and are designed for fixing on-site trade by means of a support profile 5 explained in more detail.
