Definitions

  • the present invention relates to a profile connector for connecting profile strips, in particular frame profiles of insect screens, with at least two plug-in sections designed for insertion into the profile strips, wherein the plug sections each have at least one recess on their surface. Furthermore, the invention is directed to a profile frame and an insect screen with a profile frame.
  • Profile connectors of this type are used for example for producing frame profiles of insect screens.
  • the profile strips are usually for example made of aluminum or plastic hollow profile strips that are mitred to be assembled to form a rectangular frame profile, for example.
  • the profile connectors have two, for example, mutually perpendicular plug-in sections, of which one is completely inserted into one of the hollow sections, so that the two hollow profiles abut each other in miter. Subsequently, the profile strips are pressed by means of a pressing tool with the plug-in sections of the profile connector used.
  • each recesses are formed in the surface of the plug-in sections, into which, when the profile connector is inserted, a wall section of the profile strip arranged in the region of this recess is pressed.
  • a disadvantage of these profile connectors is that for producing the press connection, a corresponding pressing device is required, so that the preparation of corresponding frame profiles is relatively complicated and expensive. In addition, a subsequent separation of the interconnected moldings is no longer possible.
  • this object is achieved in that in each case a plastic existing clamping element is arranged in the recess, which protrudes at least partially over the surface of the plug portion.
  • An inventively designed profile frame comprises a plurality, in particular four profile strips, wherein in each case two profile strips are connected by a profile connector designed according to the invention.
  • An insect screen formed according to the invention comprises a profile frame designed according to the invention and a fabric spanned between the profile strips of the profile frame.
  • the invention thus carried the attachment of the moldings on the profile connector not by corresponding indentations, but by special provided on the profile connector, made of plastic Clamping elements.
  • These clamping elements are held in each case in a recess of the profile connector and project at least partially over the surface of the respective plug sections, that on the one hand insertion of the plug sections in the hollow profile strips is possible, on the other hand, however, the inserted plug section by a corresponding friction connection of the clamping element with the Inner wall of the hollow profile strip prevents withdrawal or at least made more difficult.
  • the desired friction between the clamping element and the material of the profile strip can be adjusted by appropriate material properties of the plastic used and on the other can be ensured at the same time that due to the plastic material damage to the inner wall of the profile strip is avoided and a subsequent separation of the compound is basically possible.
  • the respective desired shape of the clamping element can be made very simple due to the formation of plastic, at the same time by the use of plastic, the clamping element is very inexpensive to produce.
  • the recess forms an undercut for the clamping element at least in the insertion direction. This is achieved in a simple manner, in particular without additional fasteners, that the clamping element is not displaced when plugged into the profile strips, but is held in its original position in the recess of the profile connector. As a result, a very simple and cost-effective production of the profile connector according to the invention is possible.
  • the recess additionally forms an undercut for the clamping element in a direction transverse to the insertion direction.
  • an even better fixation of the clamping element in the recess of the profile connector is achieved without additional fasteners would be required. It remains for the clamping element only single translational degree of freedom, which is required for insertion of the clamping element in the recess. By blocking two translatory degrees of freedom, the clamping elements are held securely without additional fastening means in the recesses so that they are arranged in particular captive.
  • the clamping elements are each held in a form-fitting manner in the recess.
  • the positive connection between clamping element and recess can be achieved by a respective, at least partially complementary configuration of the outer contour of the clamping elements and the corresponding inner contour of the recess.
  • the connection between the clamping element and the recess is formed as a dovetail connection, with the two substantially mutually perpendicular translational degrees of freedom are blocked and only the third translational degree of freedom allows a corresponding movement of the clamping element relative to the recess having plug-in portion.
  • the region of the clamping element projecting beyond the surface of the plug-in section preferably has an insertion bevel sloping in the insertion direction. In this way it is achieved that an insertion of the respective plug-in sections in the moldings with reduced force is possible while pulling in the opposite direction prevents or at least significantly more difficult.
  • the clamping element consists of an elastic plastic.
  • the plug-in sections are made of metal, in particular of a light metal or a light metal alloy, preferably of aluminum or an aluminum alloy.
  • the plug-in sections can be formed as individual parts and connected to each other or formed integrally with each other.
  • the plug-in portions are arranged substantially at right angles to each other.
  • corresponding corner connectors for frame profiles can be created.
  • the plug-in sections are arranged at a different angle to each other from the right angle to each other, for example, to provide corresponding non-rectangular frame profiles.
  • the arrangement at an angle of 180 ° is possible to connect, for example, two profile strips lying in the longitudinal direction one behind the other.
  • the profile connectors have more than two plug-in sections, for example three or four mating sections to create T-shaped or cross-shaped connections of moldings.
  • a plurality of recesses are formed with clamping elements at each plug-in portion.
  • a clamping element may be arranged in the region of an insertion-side end of the plug-in section and a further clamping element in the region of the opposite end of the plug-in section.
  • further recesses can also be formed on the plug-in sections, via which a compression of the profile connector with the profile strips can take place in a known manner in order, for example, to further increase the stability of the connection.
  • the profile connector for connecting a corner connector is formed as an angle profile, wherein the clamping elements each protrude beyond the outer surface of the angle profile.
  • the arrangement of the clamping elements is also possible in such a way that they project beyond the inner surfaces of the angle profile or over these side surfaces.
  • the recesses are formed as grooves or as openings.
  • a groove-shaped design of the recesses is particularly suitable in relatively narrow surfaces of the plug-in sections, while Openings, ie recesses, which extend completely through the material of the plug-in sections, in particular in wider surface areas of the plug-in sections are possible.
  • Fig. 1 shows four moldings 1, which are each formed as hollow profiles and are mitred at their ends to be assembled into a profile frame.
  • one profile connector 2 designed as a corner connector is arranged, each of which comprises two plug-in sections 3 arranged perpendicular to one another.
  • the profile connectors 2 are formed axially symmetrical to their respective bisectors.
  • a mesh fabric 4 is arranged, which is hung after assembly of the profiled strips 1 in grooves 5 of the moldings 1 in a conventional manner, so that ultimately an insect screen is generated.
  • profile connector 2 The detailed structure of the profile connector 2 is described below with reference to FIGS. 2 and 3 described in detail.
  • the plug sections 3 each form a leg of the integrally formed profile connector 2 and are preferably made of a light metal, such as aluminum.
  • the connectors 3 can also be made of a different material, in particular of a plastic material, as long as the required stability of the profile connector can be ensured.
  • the profile connector 2 has outer surfaces 6, in which a plurality of recesses 7, 8 is formed.
  • the recesses 8 have their extension in the longitudinal direction of the respective plug section 3 limiting Side walls 9, which are arranged obliquely so that the recesses 8 expand toward the outer surfaces 6 out.
  • each consisting of a plastic clamping element 11 is arranged, which is received positively in the recess 7.
  • the clamping element 11 lies substantially flat on the bottom of the respective recess 7 and has obliquely extending side surfaces 12, which are inclined corresponding to the walls 10.
  • the thickness of the clamping elements 11 is at least partially greater than the depth of the recesses 7, so that the clamping elements 11 protrude in regions over the outer surface 6, as it is made Fig. 2 can be seen.
  • the over the outer surfaces 6 projecting portion 18 of the clamping member 11 is provided in each case with an insertion bevel 13, which is formed in each case sloping towards the free end 14 of the respective plug section 3.
  • the width of the clamping elements 11 substantially corresponds to the width of the plug-in sections 3, so that the side surfaces 15 of the entire profile connector 2 are substantially smooth and flat.
  • clamping elements 11 Due to the protruding over the outer surface 6 areas 18 of the clamping elements 11 takes place a clamping or frictional connection between the inside of the cavity of the moldings 1 and the profile connector 2. Due to the formation of the clamping elements 11 made of plastic these are compared to those made of harder material trained plug-in sections 3 compliant, so that a corresponding deadlock between the profile strip 1 and profile connector 2 takes place.
  • the second plug-in portion 3 is inserted in the same way in the second profile strip 1 until the two miter cuts of the profile strips 1 abut each other seamlessly.
  • the other profile strips 1 are each connected to each other via corresponding profile connector 2, so that ultimately a closed and inherently stable frame profile is generated.
  • a corresponding fabric for example in the form of an insect screen mesh fabric, an anti-electrosmog fabric or other covering, for example for sun protection.
  • the recesses 8 can be used in addition to or in the event of non-use of the clamping elements 11 to allow in a conventional manner an attachment of the profile connector 2 by appropriate pressing with the moldings 1.
  • the recesses 17 can be used.
  • a reduced weight of the profile connector 2 is achieved by the recesses 17.
  • Fig. 4 shows an embodiment of a profile connector 24 with clamping elements 20 which have a substantially circular cross-section and are arranged in recesses 21 which have a corresponding part-circular cross-section.
  • a region 30 of the respective clamping element 20 projects beyond the outer surface 6 of the respective plug-in section 3, so that the clamping according to the invention with the profile strips 1 is ensured.
  • Fig. 5 shows further embodiments of clamping elements 22 with different shapes as well as correspondingly formed recesses 23 with adapted to the clamping elements 22 forms.
  • the illustrated four different clamping elements 22 are shown only as an example on a single plug-in section.
  • the clamping elements can be connected to a plug-in section or to a profile connector each identical or as in Fig. 5 shown to be designed differently.
  • clamping elements 22 are each formed so that they each form with the corresponding recesses 23 undercuts in and against the insertion direction and transversely thereto to be securely attached both during insertion and when pulling out the profile connector 2 and moreover falling out in a direction perpendicular to the outer surface 6 and to the inner surface 16 to prevent.
  • the recesses 26 has in the form of openings or holes. These recesses 26 extend from a side surface 15 through the respective plug portion 3 to the opposite side surface 15 and have a substantially circular cross-section.
