Definitions

  • the invention relates to a corner connector for door and window frames, with a rectangular cross-section shank for insertion into a mitered frame hollow section and the shaft final, weldable or glued, according to the miter of the hollow profile extending inclined surface and a spreading of a The spreading of the rectangular surfaces of the shaft spreading device for clamping the shaft in the hollow profile.
  • Such corner connectors are known in numerous embodiments.
  • An expanding wedge is used by the applicant by means of a screw screwed in from the inclined surface over an inclined surface of the shank.
  • the expanding wedge increases, so that it braces in the interior of the hollow profile.
  • the wedge forms a spreading part, which increases the cross-section of the corner connector and thereby reaches the tension.
  • the DE 91 13 235 U1 shows a corner connector, which also has a wedge as a spreading, but this is not pushed by means of a screw, but one of the wedge directly molded tongue in the corner connector or pulled out of this.
  • the Applicant described a solution in which between the wedge-shaped expansion part and the inner surface of the hollow profile is a pressure plate which is pressed by the expansion part to the outside and ensures that the wedge is displaced in its longitudinal displacement on the always same inner surface of the printing plate, so that the tensile or compressive force with which the wedge has been moved is always a measure of the tension achieved.
  • a disadvantage of this known solution is that the injection molding tool to be used is relatively expensive and the corner connector is accordingly expensive.
  • the invention is therefore an object of the invention to provide a corner connector of the type mentioned, which can be produced with relatively simple tools, so that the production costs are relatively low.
  • the spreading device is designed as a studded band and that the expansion part on the side facing the spreading device has dome-shaped recesses which engage over the knobs.
  • the knobs migrate to the edges of the respective associated dome-shaped cavities, the expansion part is pressed from the shaft, so that the shaft is clamped in the hollow profile.
  • the expansion part can be pressed both directly against the inner surface of the hollow profile, as well as a pressure plate, as shown in the aforementioned European font.
  • the nubs are preferably formed substantially hemispherical.
  • the rounding to the tension side prevents the knobs get caught in the dome-shaped recesses of the expansion.
  • the rounding on both sides allow a lateral tilting of the expansion part, so that this can adapt to the inner profile of the hollow sections, which differ in their dimensions relative to the standard.
  • a plurality of knobs are arranged in a row on the drawstring, so that distribute the forces that must be applied for lifting the expansion, over the entire length of the drawstring.
  • the drawstring at its front ie the end directed to the inclined surface have an eyelet, which is located in a recessed recess of the inclined surface and can be detected here with a tool.
  • This tool can be designed so that it is supported on the miter surface of the hollow profile when exercising the tensile force and thus ensures that the corner connector, if it is set in motion of the tensile force in the direction out of the hollow profile in motion, by the tool is held in a flush position with respect to the hollow profile.
  • Fig. 1 shows a corner connector according to the invention.
  • the corner connector has a rectangular cross-section shaft 10, which is closed by an inclined surface 12.
  • the inclined surface 12 serves as a welding surface which is welded to a corresponding offset by 90 ° arranged welding surface of another corner connector.
  • the shaft 10 is inserted into a hollow profile of a window or door frame.
  • the hollow profile is stiffened by a square tube 14 made of metal, which is inserted into the window hollow profile.
  • This stiffening profile 14 is not cut mitred, but just cut off.
  • the corner connector is located directly in this stiffening profile 14th
  • the corner connector according to the invention has on the upper side of the shaft, a spreader 16 which upwards in Fig. 1 can be raised and clamped in this way the shaft 10 in the hollow profile, more precisely in the stiffening profile 14.
  • a spreading device 18 is provided, which has the shape of a tension band with a series of knobs 20,22,24.
  • the knobs 20,22,24 form substantially hemispherical elevations of the inherently flat band. It may also be semi-cylindrical ribs, as shown in the drawing.
  • the spreading device or the band 18 can be pulled out of the corner connector to the right. This will be explained later in detail.
  • the knobs When moving to the right in Fig. 1 the knobs move 20,22,24 along the bottom of dome-shaped recesses 26,28,30. Since the inner height of the dome-shaped recesses decreases towards the edges, the spreading member 16, while the tension band, which forms the spreading device 18 is pulled to the right, gradually raised. As a result, the corner connector is clamped in the hollow profile.
  • the knobs 20,22,24 not return within the dome-shaped recesses 26,28,30, the surfaces of the knobs and the recesses are formed in a suitable manner self-locking, as indicated in the drawing by the illustrated zig-zag profile.
  • the drawstring which forms the spreading device 18, is provided at its right end with an eyelet 32.
  • the eyelet 32 can be detected from the outside of the inclined surface 12 forth with a suitable tool that the eyelet and thus the entire tension band to the right in Fig. 1 emotional.
  • the eyelet 32 is located in a recess 34 in the inclined surface 12 of the corner connector, which is only indicated by dashed lines in the drawing.
  • Fig. 3 to 5 show the spreading device 18, which is formed by the tension band, in different views.
  • Fig. 3 is a perspective view and Fig. 4 a side view while Fig. 5 a cross section to Fig. 4 represents.
  • the shape of the dimples 20, 22, 24 can in practice be quite different from what is shown in the drawing. It is particularly advantageous to form the nubs substantially as hemispherical, ie not only to round off in one dimension, such as for example Fig. 3 shows, but in two mutually perpendicular dimensions. In this way it is achieved that the expansion part 16 can tilt laterally and can adapt to irregular shapes of the hollow profile or the stiffening profile 14.
  • Fig. 6 shows the spreading device 18th
  • Fig. 7 indicates that the expansion part 16 is box-shaped with inner stiffeners.
  • the spreading device serving drawstring 18 by means of the eyelet 32 to the right in Fig. 1 can be pulled out in the direction of the corner connector.
  • a pulling device not shown, which can dive with a hook in the recess 34 in the inclined surface 12 and moves the eyelet in the direction of the inclined surface 12 out.
  • the pulling tool can be supported at the same time on the inclined surface 12 and on the front edges of the hollow profile, as is the case for example in the aforementioned European patent.
  • the solution according to the invention has the advantage that the expansion part is uniformly lifted over the entire length during clamping of the corner connector.
  • the bracing is therefore not only in the rear end, for example, as is the case in many systems.
  • the nubs can have a different shape. For example, they may be formed as a hemisphere.
  • the nubs may also take the form of shafts extending across the corner connector. The most convenient, however, is likely to be a shape that is substantially hemispherical and also allows tilting to the side, as explained above.
  • Fig. 5 is not quite true in this respect, since here the shoulders of the nubs are shown in the drawing angular. Similar to embodiments Fig. 5 However, also come into consideration.
