Definitions

  • the invention relates to a connecting piece for two angularly abutting profile bars of window or door frames, which can be placed on the outside of a frame bar and fastened to it with a connecting part penetrating this frame bar, which engages in a metal body of a central body of the connecting piece designed as a hollow profile, the The central body can be inserted on the face side into a cavity of a crossbar, to which the connecting piece can also be fastened.
  • Such a connector is known from DE-U-8 510 869.
  • the central body of the known plastic connector is cross-sectionally adapted to the cavity of the crossbar, in which the central body is inserted.
  • a threaded sleeve designed as a metal body is arranged in the interior of the known central body and fastened to the central body by extrusion coating.
  • the known central body has a large cross-sectional design to be able to take over the forces to be transmitted between the profile bars.
  • a generic connector which, however, does not have a central body designed as a hollow profile. Rather, two non-one-piece bodies are present on both sides of a metal body. These clasp the metal body in a form-fitting manner in the direction of engagement.
  • the known metal body has its main direction of extension in the direction of the frame bar, so that the cross bar to be connected at an angle to it is correspondingly wide.
  • the known connecting piece has a large cross-sectional configuration and is in particular not suitable for narrow cross bars.
  • the invention has for its object to improve a connector of the type mentioned so that it can be used even with a small cross-section and in particular for narrow cross bars.
  • the metal body completely fills the hollow profile of the central body and has a profile tapering from the frame rod into the cavity of the cross rod.
  • the metal body completely fills the hollow profile of the central body.
  • the metal body thus takes on the one hand the stiffening of the central body, so that it can be made considerably smaller in cross-section; because the strength of the entire central body is practically determined by its metal body component.
  • the metal body has a profile tapering into the cavity of the crossbar.
  • the central body can be kept narrow in cross section, in particular in the directions of the frame rod, so that the crossbar to be connected to the frame rod can accordingly be kept narrow.
  • a narrow crossbar means not only less material expenditure, but above all a gain in window or door area or a gain in area for light entry.
  • the connector according to the invention is therefore an essential prerequisite for increasing the translucent window surface with otherwise unchanged dimensions.
  • the connecting piece is expediently designed such that the central body consists of thin-walled plastic. This results in the greatest possible stiffness of the connecting piece through a maximum possible and thus greatest stiffness ensuring metal body with the smallest possible wall thickness of the central body, which is essentially determined only by the cross-sectional shape of the cross bar to be connected or a metal stiffening profile of the cross bar provided in this cross bar.
  • the metal body has a profile that tapers in sections from the frame rod into the cavity of the cross rod.
  • the metal body can have the required material thickness in the area of the attachment of the connecting part, while outside of this engagement area it is reduced to a thickness that is at most necessary for other reasons of stiffness.
  • this reduction outside the engagement area of the connecting part also serves to keep the central body small in cross section, in particular in the directions of the frame rod. As a result, the material expenditure for the metal body can also be minimized.
  • a special embodiment for achieving the aforementioned purposes is characterized in that the metal body has a substantially cuboid base, from which a stiffening plate set off from the base extends in the direction of the crossbar.
  • the offset between the base and the stiffening plate or the consequent offset of the central body also serves as an insertion boundary surface of a steel tube, which stiffens the crossbar to be connected.
  • the tapered profile is a wedge profile, which can be extrusion-coated during the manufacture of the connecting piece, but which can also be inserted with good clamping in an already finished connecting piece, for example a metal one.
  • the metal body has cross-ribs which act like barbs and support the fixing of the metal body in the central body.
  • the metal body is made of die-cast zinc, which on the one hand achieves the required strength and on the other hand the desired shape can be easily produced.
  • the metal body has a recess on the frame rod side which is adapted to a seal holding profile of the frame rod. This design ensures that the metal body extends as far as possible up to the outer surface of the frame rod in spite of the sealing retaining strip present on the frame rod.
  • the metal body has a screw thread which fixes the connecting part in the metal body or a clamping device.
  • a simple screw connection can be used between the metal body and a connecting part in order to establish a stable connection.
  • Such a stable connection can also be achieved via the clamping device.
  • the clamping device is adapted to the particular design of the metal body. It is an advantageous embodiment if the clamping device is a blind bore with a clamping screw that can be adjusted transversely in the metal body and that can be actuated from outside the central body. With such a clamping screw, the connecting part can be fastened at different points along its longitudinal extent.
  • the connecting part is advantageously a bolt which has at least at one end a clamping surface which can be acted upon by the clamping device.
  • the clamping surface and the clamping device can be specially matched to one another, so that the holding effect of the clamping device can be increased in this way.
  • the clamping surface is inclined to reinforce the tightening and if necessary one end of the bolt has a screw adjustment handle.
  • the tightening inclination of the clamping surface it can be achieved that the metal body to be connected or the connecting piece to be connected is subjected to force in the direction of the connecting part and is consequently pulled against the frame rod, so that the fit of the crossbar is improved, in particular in a system of the crossbar on the frame rod.
  • the connecting part can be subjected to a screw adjustment, so that a screw thread of the connecting part can be screwed into a screw thread of the metal body.
  • the connecting part is fastened at one end to a first connecting piece and at the other end to a second connecting pin located opposite the frame rod.
  • a connector can be Instead of a frame bar, connect two cross bars arranged in alignment with the frame bar to form a bar cross.
  • the connection strength of this cross bar is practically only determined by the engagement strength of the connecting part in the metal pieces, that is, without using the load-bearing capacity of the frame rod, as is given when a single connection piece is separately connected to the frame rod.
  • very stable cross connections can be produced, in particular if the ends of the connecting part each engage a stiffening metal body of the respective connecting piece.
  • the connector 10 of FIG. 1 has a central body 11, in which a metal body 12 shown in dashed lines is inserted.
  • the central body 11 extends essentially in the direction of a crossbar to be connected, for example in the direction of a fighter or a Rung of a window.
  • the connecting piece is fastened with fastening legs 13, which are arranged essentially parallel to the central body 11 and are held on this by projections 14, which extend transversely thereto or in the direction of the frame bar with which the connecting piece 10 must also be in a fixed connection.
  • This frame bar like the cross bar, is not shown for the sake of simplicity, because it is known per se, cf. B. DE-GM 85 10 859.
  • the design of the mounting leg 13 is known, insofar as they are angularly shaped with their cross-section, the angle leg 13 'fits between a contact surface of the frame rod for the angle leg 13' and a retaining strip of the crossbar, in order to provide a precisely fitting connection between the Cross bar and the frame bar to contribute.
  • the angle leg 13 ' reinforces the angle leg 13 ⁇ , which is weakened in its central region by a recess 25, which is required for the engagement of an elastic sealing strip or a recess of a rollover profile of the frame bar.
  • the angle leg 13 ⁇ is flush with the connector-side contact surface of this frame roll-over profile, namely in the region of its lower fastening hole 26.
  • each fastening leg 13 is firmly screwed to the frame rod and to the transverse rod with the aid of the fastening holes 26 to 28. If necessary, the fastening legs also serve to glue the connecting piece to the frame and crossbar.
  • the central body 11 of the connecting piece 10 has a base 30 which has a shoulder 31 for a hollow tube engagement part 32.
  • This pipe engagement part 32 is pushed the stiffening tube when connecting the crossbar, which comes to rest at a distance or in contact with paragraph 31 on the pipe engagement part 32 with one end, which is centered by guide ribs 33 of the pipe engagement part 32.
  • the base 30, like the tube engagement part 32 of the connecting piece 10, is also hollow and the metal body 12 is arranged in this cavity 33 and in the cavity 34 of the tube engagement part 32.
  • FIGS. 2, 3 it can be seen that the central body 11 of the connecting piece 10 is hollow with thin walls and is completely filled inside by the metal body 12.
  • FIG. 3 shows that the central body 11 is very narrow in a transverse axis, that is to say transversely to the transverse rod into which the central body 11 is inserted, so that the transverse rod can be dimensioned to be correspondingly narrow.
  • the stiffening effect of the metal body 12 on the central body 11 is completely sufficient, that is to say horizontally in the plane of the illustration, especially since there are rollovers of the crossbar to be connected in these directions and are supported on the frame bar, so that the load on the metal body 12 is comparatively low.
  • Fig. 4 shows the formation of the metal body 12 in perspective and in particular lets Recognize the design of the base 17 and the reinforcing plate 19.
  • the base 17 is essentially cuboid and has a shoulder 35, from which the stiffening plate 19 extends in the direction A, ie in the direction of the crossbar to be connected. 5 that the stiffening plate 19 tapers into the cavity of the crossbar. This taper is wedge-shaped, so that the stiffening plate 17 has a wedge profile.
  • transverse ribs 16 are arranged, which run parallel to the extension of the frame bar and around the base and are present on the large areas of the stiffening plate 19. According to FIG. 3, these transverse ribs 16 increase the connection strength of the central body 11 with the metal body 12 by pulling it downward in the plane of the illustration. If the metal body 12 is assembled by pushing it into the central body 11, the shoulder 35 acts as an insertion limiting stop.
  • a connecting part which engages on the frame rod on the one hand and cooperates with one end with a clamping device 21 of the connecting piece.
  • This clamping device 21 is arranged in the metal body 12 and consists essentially of a blind hole 18 in the longitudinal direction of the metal body 12, and of a clamping screw 22 arranged transversely to this blind hole 18, which is shown as a grub screw. An adjustment of this grub screw into the blind hole 18 leads to a clamp fastening of the connecting part, not shown. Another possibility of the engagement of such a connecting part can be seen from FIG.
  • a connecting part 20 into the metal body 12 is not shown in more detail in the usual manner and as a result is screwed into place, with the aid of a screw adjustment handle 24, which is provided on the free end of the connecting part 20 in the form of a bolt in the form of a slot for engagement by a screwdriver.
  • a fastening screw can also be used, which is supported with its head in the usual way on a fastening surface of the frame rod if it is screwed sufficiently far into the threaded bore of the metal body 12 or the central body 11 of the connecting piece 10.
  • the connecting part 20 of FIG. 6 is used specifically to connect the connector 10 with another connector 10 '.
  • the connecting part 20 is screwed into a screw thread of the metal body 12 by means of the screw adjustment handle 24.
  • the connecting part 20 is arranged in the direction of the longitudinal extent of this metal body 12 or of the central body 11.
  • the connecting part 20 designed as a bolt, the connecting piece 10 must be fastened to the frame rod 36, which is shown schematically, for which purpose the connecting part 20 passes through this frame rod 36, for example, through a bore 37, also shown schematically. It is on the side of the connector 10 'and is able to engage with its end in a bore of the metal body 12 of the connector 10', which is formed according to the blind hole 18 in Fig. 2.
  • a clamping surface 23 is provided at this engaging end of the connecting part 20.
  • On this clamping surface 23 acts a clamping screw 22 with which the connecting part 20 is fixed in the metal body of the connector 10 '.
  • the two connecting pieces 10, 10 ' are thus firmly connected to one another, including the frame rod 36 transversely to its longitudinal extent.
  • the clamping surface 23 has a tightening effect because it is conical or tapered towards the frame rod 36.
  • the clamping screw 22 pressing on such an inclined clamping surface 23 thus pulls the connecting piece 10 in FIG one direction and the connector 10 'in the opposite direction against the frame rod 36.
  • the two connecting pieces 10, 10 ' can each engage with their central bodies 11 in the ends of a crossbar, not shown, and can be fixed to this crossbar.
  • a cross-shaped cross bar / frame bar connection is essentially created by means which also serve to produce a T-shaped connection between a single cross bar and the frame bar.
  • the central body of the connecting piece and preferably also the fastening legs carried by it consist of plastic, which is reinforced by the metal body.
  • the plastic used is the material that is also used for the frame spars of the window or door frames.
  • the central body or the connecting piece could also be made of metal, the cavity itself serving to save material.
  • a metal body is only used if it is used for additional attachment of the central body, for example when creating a cross-shaped connection from frame and cross bars.
