Definitions

  • the present invention relates to a corner connector for hollow profile frame according to the preamble of claim 1.
  • corner connectors are used to connect the mitered end portions of two hollow sections of a frame, such as a window or door frame at right angles to each other.
  • the corner connector comprises for this purpose an elbow with two legs, each of which can be inserted into the end portions of the hollow sections to be connected and anchored or braced therein.
  • the connection should have the required stability, on the other hand, however, to avoid high pressures or stresses in the frame, so that no damage occurs.
  • hollow frame profiles are also made of a mixture of materials, which in addition to plastic also contains wood or wood-based materials, such as wood flour or the like. This is desirable for the sake of a resource-conserving and thus environmentally friendly production, since here also recycled materials can be used.
  • wood or wood-based materials such as wood flour or the like.
  • wood or wood-based materials such as wood flour or the like.
  • these materials are comparatively new in window and door construction and make special demands with regard to the corner connectors.
  • Such hollow profiles can be held together with high compressive loads, which can not be applied by the previously known corner connectors, which use a spline connection. However, it is important to control the load, ie to apply it with a given force. In the known angle connectors, this is not readily possible.
  • Object of the present invention is therefore to provide a corner joint for hollow profile frame, which is easy to install and reliable and allows the application of high pressure loads on the joint with controlled effort. Another object is to provide such an angle connector which centers the hollow sections of the frame itself and clamped together.
  • one of the two legs of the angle piece is supplemented at its end by a clamping piece which lies in the extension of the leg axis and is displaceable along the latter, so that the rest of the angle piece is movable relative to the clamping piece.
  • Both legs have lateral wedge-shaped recesses, on the wedge surfaces of a wedge rests such that its tip is oriented towards the corner of the elbow.
  • the wedges can be slid on the wedge surfaces, especially in the direction of the corner.
  • the wedge, which rests in the first leg and will be referred to as the first wedge in the following, is firmly connected at its side with the clamping piece, so that it is carried along with a relative movement of the clamping piece with this and slides on the wedge surface.
  • the clamping piece is as well as the remaining second leg anchored in the respective end portions of the hollow profile, for example by anchor bolts.
  • a clamping screw is guided axially from the corner of the angle ago by a channel in the first leg and extends into the clamping piece and is screwed into this.
  • a rotation of the clamping screw is thus converted into a sliding movement of the clamping piece.
  • the legs of the elbow are due to the sliding movement of the wedges on the corner to the lateral direction, d. H. widens transversely to the clamping direction. So not only the miter cut surfaces of the hollow sections are pressed against each other, but there is also a lateral splaying of the legs held within the hollow sections, which gives this additional support and determines their position.
  • the opposite side of the wedges of the elbow serves as a reference page for the positioning in the hollow profile, which always rests on the inside of the channel in profile for receiving the respective leg.
  • the first leg is inserted together with the clamping piece and the first wedge in a Hohlprofilendabêt until a defined position is reached, in which the head of the clamping screw is exposed at the corner of the elbow in an opening of the hollow profile.
  • the clamping piece is anchored in its hollow profile, for example by anchor bolts, which are screwed from the outside through the wall of the hollow profile in the clamping piece.
  • the end portion of the remaining hollow profile section is pushed onto the second leg with the second wedge until an internally threaded bore in the second leg is aligned with a corresponding opening in the outer wall of the hollow profile, so that an anchor screw can be screwed therein, the second leg in its hollow profile anchored.
  • the tightening screw is turned so that the first leg is pulled toward the firmly anchored tension piece until the miter cut surfaces (via the seals mounted thereon) come into contact with each other.
  • the first wedge connected to the clamping piece is clamped to the underlying first leg. Since a lateral force component transversely to the clamping screw occurs when the miter surfaces meet, this causes a lateral displacement of the transverse to the clamping screw stationary hollow section end portion and thus the bracing of the second leg therein.
  • the clamping piece and the second leg are anchored in the respective end portions by anchor bolts, which are screwed from the outside through the walls of the end portions in the clamping piece and the second leg.
  • the recesses are formed by cutouts in the legs, whose base surfaces form the wedge surfaces on which the respective wedge slidably rests with its underside.
  • the clamping piece is located in a recess at the end of the first leg.
  • a pin which points to the tip of the wedge and rests in a guide hole in the end of the second leg.
  • corner connector 10 is used to connect two hollow sections of a frame, such as a window or door frame.
  • this corner connector 10 is not suitable exclusively for use on window or door frame profiles, but is equally suitable for hollow profile frames of other types, such as for receiving photovoltaic modules or the like.
  • the corner connector 10 is formed overall L-shaped and includes an elbow 12 with two legs 14,16, which will be referred to in the following as the first leg 14 and second leg 16.
  • the legs 14, 16 are at right angles to each other and are provided for insertion into the end portions to be joined two hollow sections of the frame.
  • the angle piece 12 is made of plastic, and the two legs 14,16 are formed integrally with each other at the corner 18. On their outer surfaces, which are remote from the other leg, the legs 14,16 ribs 19 which extend along the respective leg 14,16.
  • the legs 14,16 have substantially the same length.
  • the first leg 14 on the left in Fig. 1 has at its free end a central, approximately rectangular recess 20. It serves to receive a clamping piece 22 which can be inserted along the leg axis S of the first leg 14 into the recess 20. This inserted state is in Fig. 2 shown.
  • the legs 14,16 On their tops in the Fig. 1 and 2 the legs 14,16 have lateral cutouts 24,26. These extend substantially along the respective leg axis and are approximately wedge-shaped, such that the depth of the cutout 24,26 gradually increases from the corner 18 in the direction of the ends of the legs 14,16. The respective bottom 28 of the cutout thus forms an inclined sloping from the corner 18 forth sliding surface.
  • the recesses 24,26 serve to receive wedges, namely a first wedge 30, which rests in the cutout 24 in the first leg 14, and a second wedge 32 which is received by the cutout 26 in the second leg 16.
  • the cross section of the wedges 30, 32 is essentially the same. Both wedges 30,32 have a flat underside wedge surface for resting on the respective bottom 28 of the cutout 24,26, and a slightly rounded in cross section top.
  • the tips of the wedges 30,32 point towards the corner 18, and their wedge angle corresponds to that of the recesses 24,26, so that the free tops of the wedges 30,32 in the inserted state in the recesses 24,26 are horizontal in a plane parallel to the plane in which the opposite sides 34,36 of the legs 14,16 lie, which are in the Fig. 1 and 2 located below.
  • the wedge 30 is integrally connected at its obtuse, the corner 18 opposite end with the clamping piece 22 and laterally (ie in the Fig. 1 and 2 above) to the clamping piece 22 is formed.
  • a displacement of the clamping piece 22 in the recess 20 in the direction of the corner 18 thus results in a corresponding displacement of the first wedge 30 in the cutout 24 in the first leg 14.
  • By sliding the first wedge 30 on the bottom 28 of the cutout 24 wedge the wedge 30 at the same time in the top Fig. 1 and 2 , ie laterally to the direction of displacement. If this displacement takes place in the inserted state of the corner connector 10 in the hollow profile, the first leg 14 is widened by the movement of the first wedge 30 and clamped in the corresponding hollow profile end section.
  • This bracing can be through a in the Fig. 1 and 2 reach clamping screw not shown, which is guided from the corner 18 forth through a channel 38 along the leg axis S in the first leg 14 and is freely rotatable in this channel 38. With its end, which projects from the channel 38 into the recess 20, the clamping screw is screwed into the clamping piece 22. By tightening the clamping screw thus the clamping piece 22 can be pulled into the corresponding recess 20, so that the first leg 14 is spread and clamped in the manner described above.
  • the second wedge 32 which rests in the second leg 16, has at its obtuse, the corner 18 remote from the end a lateral pin 40 which is laterally formed on this end and points to the wedge tip.
  • This pin 40 is intended to be fully received in the free end of the second leg 16 and there to slide in a guide hole, which in the Fig. 1 and 2 not shown in detail.
  • Fig. 2 shows a state of the corner connector 10, in which the clamping piece 22 is completely received in the recess 20.
  • the wedges 30,32 are also completely in their recesses 24,26, so that only their tops and their wedge ridges exposed at the ends of the legs 14,16.
  • Fig. 3 shows a corner of the hollow profile frame 42 from the outside in a side view. At this corner, two hollow profile end portions, namely a horizontal end portion 44 and an end portion 46 perpendicular thereto, are joined together at their miter cut surfaces 48, 50. Between the miter cutting surfaces 48,50 is a seal 52nd
  • Fig. 3 In the hollow profile frame 42 made Fig. 3 is the corner connector 10 from the Fig. 1 . 2 and 4 one.
  • Fig. 4 shows the corner connector 10 again in a view corresponding to the orientation of the hollow profile frame 42 in Fig. 3 ,
  • the first leg 14 is therefore in in Fig. 3 vertical end portion 46, while the second leg 16 rests in the remaining horizontal end portion 44.
  • Fig. 6 shows the second leg 16 with its anchor bolts 56.
  • the structure of the second leg 16 is on the one hand to ensure good stability and bracing in the end portion 44, on the other hand be designed to save material.
  • the ribs 18 make a good compromise between these requirements.
  • Fig. 7 shows the other hollow-profile end portion 46. On the outside thereof also extends a groove in which the anchor bolts 54 are sunk for the clamping piece 22 in the interior of the end portion 46.
  • Fig. 8 For example, the outer side of the first leg 14, which rests in the hollow-profile end portion 46, a similar outer structure as the second leg 16.
  • the construction of the clamping piece 22 with the anchor bolts 54 inserted therein is also clearly visible.
  • the clamping piece 22 comprises a laterally widened head 60, which rests in the recess 20.
  • the head has slightly wedge-shaped outer surfaces 62 running towards one another, which are pressed into the recess 20 in the lateral boundary surfaces of the recess 22 when the tensioning piece 22 is pulled in.
  • the clamping screw 58 is in Fig. 8 also partially recognizable.
  • Fig. 9 is a section along the plane AA in Fig. 5 which extends along the axis of the clamping screw 58. It shows how the first leg 14 of the corner connector 10 rests in the hollow profile end portion 46.
  • the section through the clamping piece 22 also shows here how the first wedge 30 laterally on the head 60 (see Fig. 8 ) of the clamping piece 22 is formed and how the wedge 30 and the remaining part of the first leg 14 complement each other to a substantially rectangular cross-section.
  • FIG. 10 For a better overview of the first leg 14 and the clamping piece 22 with the molded thereon first wedge 30 in Fig. 10 optional.
  • This sectional view in Fig. 10 is in a level BB in Fig. 6 ,
  • FIG. 11 shows a section through the hollow profile end portion 44 with the inserted therein and strained second leg 16 of the corner connector 10. Also visible is a longitudinal section through the second wedge 32 with the formed thereon pin 40, in the guide hole 64 at the end of the second leg sixteenth rests.
  • the anchor bolts 56 for anchoring the second leg 16 in the hollow profile end portion 44 are also recognizable, as well as a cross section through the clamping screw 58th
  • Fig. 12 is the second leg 16 with the second wedge 32 released and shown without the hollow profile end portion 44.
  • the wedge 32 is slightly displaced together with pin 40 to the free end of the second leg 16, ie, the pin 40 is slightly pulled out of the guide hole 64.
  • the second wedge 32 slightly spreads the cross section of the second leg 16 and tightens it within the hollow profile end portion 44. This is accomplished by a slight displacement of the end portion 44 together with the second leg 16 anchored therein as an evasive movement if, when tightening the clamping screw 58, the miter surfaces 48, 50 are pressed against one another.
