Definitions

  • the invention relates to a connector for two angularly abutting frame bars of window, door or the like.
  • Frame which is seated on the outside of a frame rod and is fastened to it by a screw connecting part which penetrates this frame rod and which is screwed into a metal body which stiffens the hollow connecting piece on the inside.
  • a connector with the aforementioned features is known from German utility model 87 07 233.
  • the metal body serves to stiffen a hollow central body of the connecting piece, which is made of thin plastic walls.
  • the metal body completely fills the central body.
  • the metal body has a substantially cuboid base, from which a tapered spline extends between the thin walls of the central body of the connector.
  • the known screw connection part a bolt with a thread at one end, is screwed with this thread into a threaded hole in the metal body.
  • a clamping screw engaging across a wall of the connecting piece and into the metal body is provided.
  • the known connector fulfills its purpose, but can still be improved. This is because a frame rod with larger dimensions of its hollow profile is required, in particular considerable material expenditure for the metal body, and its connection to the central body of the connecting piece is not optimal, especially not with higher loads.
  • the invention is therefore based on the object of improving a connecting piece with the features mentioned at the outset in such a way that it is more suitable for larger frame cross sections and is in a simple manner suitable for higher pull-out loads on its metal body.
  • the screw thread of the metal body is arranged in a base plate which bears against a closing wall on the frame-rod side of the hollow connecting piece except for an opening for the screw connection part, and in that the metal body is tubular from the base plate and its tube walls are Support the walls of the connector.
  • the metal body is hollow, which results in a corresponding material saving compared to a full metal body.
  • the hollow metal body can be adapted to practically all cross-sectional shapes without sacrificing strength.
  • suitable stiffening walls must be used in the interior of the hollow metal body.
  • Such a metal body should also be regarded as tubular in the sense of the invention. It is important that the tube walls support the walls of the connector so that its thin plastic walls get the necessary support.
  • the connector does not necessarily have to be made of plastic.
  • a metal connecting piece could also be stiffened with a stiffening metal body, whereby an otherwise sufficient connecting piece could also be used in such cases in which it would not meet the strength requirements with regard to the stiffened part per se.
  • the stiffening effect is particularly often required when the connecting piece is made of plastic.
  • the tubular design of the metal body is supplemented by the fact that the latter has a base plate which the screw thread for Has fastening of the screw connection part and which abuts the end wall of the connecting piece. This system produces an axial positive fit that easily satisfies all the axial pull-out loads of the metal body that occur.
  • the connecting piece is expediently designed such that the base plate has a metal cylinder projecting in both longitudinal directions of the metal body and having an internal thread for the screw engagement of the screw connection part.
  • the thread engagement length between the metal body and the screw connection part is sufficiently large to be able to transmit extremely large fastening forces of the screw connection part to the metal body.
  • the base plate can be made comparatively thin and can be arranged in the vicinity of the frame rod to be connected, so that the stiffening effect of the tubular metal body on the connecting piece already begins in the vicinity of this frame rod.
  • the end wall of the connecting piece has an inner projection with a recess in which the end wall-side part of the metal cylinder is fully accommodated, it is thereby achieved that the entire thickness of the end wall is used to accommodate the metal cylinder increasing the thread engagement length.
  • the connecting piece In order to fill the cross-section of the connecting piece to be stiffened as completely as possible, so as to influence the stiffening effect, the connecting piece is designed such that the tube walls of the hollow metal body lie flat against at least two opposite walls of the hollow connecting piece.
  • the connecting piece is designed such that the tube walls of the hollow metal body have radially projecting wall sections integrated into a closed cross-sectional shape of the hollow metal body.
  • the stiffening of the connecting piece is easy to ensure.
  • the connecting piece has the features that the tube walls of the hollow metal body have radial wall sections projecting in sections in the longitudinal direction thereof. The wall sections projecting in sections in the longitudinal direction enable adaptations of the metal body to corresponding recesses of the connecting piece and thus optimal stiffening in the cavity of the connecting piece.
  • the connecting piece has two fastening legs parallel to the hollow metal body and attached to a frame rod to be connected, and that the wall of the central body located in the plane of the fastening leg between them has a distance from the adjacent tube wall of the hollow Metal body is arranged, which has in the center a stiffening strip extending up to the adjacent wall of the central body.
  • a special connector is provided with a specially adapted hollow metal body, which does not stiffen the cavity of the connector so that all of its four walls abut against all walls of the central body of the connector, but so that a special stiffening near a wall of the central body is achieved by a lattice-like structure of the hollow metal body, in which a tube wall is at a distance from the adjacent wall of the central body, but acts on this adjacent wall with a stiffening strip.
  • the connecting piece is designed so that the metal body can be installed in the opening of the cavity of the central body facing away from the end wall. Despite the axial positive connection between the metal body and the connecting piece or its central body in the direction of the frame rod to be connected transversely, the simple assembly of the metal body with the connecting piece is ensured.
  • the connecting piece 10 has a central body 11 which extends essentially in the direction of a crossbar 56 to be connected, that is to say for example in the direction of a fighter or a rung of a window.
  • the connecting piece 10 engages with the central body 11 or its tube engagement part 32 in a cavity of the cross bar 56 or in a metal tube of this cross bar 56, not shown, which stiffens the cross bar 56 made of plastic.
  • the connector 10 is fastened with fastening legs 13 which are arranged substantially parallel to the central body 11 and are held by projections 14 which extend transversely thereto or in the direction of a frame bar 36, with which the connector 10 is also fixed Connection must be.
  • fastening legs 13 is emphasized, insofar as they are angularly shaped with their cross section, the angle leg 13 'resting on a contact surface 36' of the frame rod 36 for the angle leg 13 '' and on a retaining strip 57 of the crossbar 56, in order to Contribute precisely fitting connection between the cross bar 56 and the frame bar 36.
  • the angle leg 13 reinforced the angle leg 13 ′′, which is weakened in its central region by a recess 25 shown in FIG. 4.5, which is required for the engagement of an elastic sealing strip or a recess 68 of a frame rollover profile 59 of the frame rod 36.
  • the angle leg 13 ′′ lies flush against the connection-side contact surface 36 ′ of this frame roll-over profile 59, namely in the region of its lower fastening hole 26. However, it also lies flush with the stop surface 56 ′ of the crossbar 56 to be connected, namely in the region of its fastening hole 27.
  • everyone Fastening leg 13 is consequently screwed tightly to the frame rod 36 and to the transverse rod 56 with the aid of the fastening holes 26, 27. If necessary, the fastening legs 13 also serve to glue the connecting piece 10 to the frame bar 36 and to the cross bar 56.
  • the central body 11 has a rib 33 projecting in the direction of the fastening leg 13, with which it engages in the hollow profile of the crossbar 56 to be pushed over and is supported on the inner wall thereof. There are others, some shown and partly Ribs not shown are present.
  • the rib 33 merges into a connecting wall 33 'between the central body 11 and the fastening leg 13, which serves to stabilize and at the same time to rest the elastic sealing strip 68 of the frame rod 36.
  • the connector 10 cut in the right half in the area of its central body 11 shows a hollow configuration of the central body 11 with a cavity 11 'into which a metal body 12 is installed. It reinforces the central body 11, which is composed in particular of plastic, and thus the entire connecting piece 10.
  • the metal body 12 is, for example, an injection molded part.
  • the metal body 12 is adapted to the cavity 11 'of the central body. It is tubular and has tube walls 44 to 47.
  • the tube walls 45, 47 lie flat against the walls 49, 51 of the hollow connector 10, just as the tube wall 46 lies flat against the connector wall 50.
  • the tube wall 44 has against it Distance from the wall 48 of the central body 11. This wall 48 lies in one plane of the fastening legs 13 or the angle legs 13 ′′.
  • the distance between the tube wall 44 and the wall 48 of the central body 11 is bridged by a stiffening strip 44 'which engages in the center on the wall 48.
  • This stiffening strip 44 ' extends in the longitudinal direction up to the vicinity of the recess 25 and with it a grid-like reinforcement structure is formed in the area near the wall 48 of the central body 11, which causes a special stiffening.
  • the walls 49, 51 of the central body 11 have radially recessed wall sections 49 ', 51'. So that stiffening is also achieved here, the hollow metal body 12 has radially projecting wall sections 45 ′, 47 ′ that widen the cavity 11 ′, the wall thickness of which is approximately equal to the wall thickness of the metal body 12 in the remaining areas, with a closed cross-sectional profile of the hollow one Metal body 12 results.
  • FIG. 2 shows that the tube wall 44 of the hollow metal body 12 has a radial wall section 58 projecting over part of the length of the metal body 12, which is indicated in FIG. 4 by the recess 58 '.
  • This wall section 58 also serves to optimally stiffen the hollow central body 11.
  • the connecting piece 10 or its central body 11 is not open on the frame rod side, but is closed by an end wall 43 which only has a through-bore 42 for a screw connection part, not shown, for example for a connecting screw.
  • a screw connection part has to be brought into engagement with the metal body 12, for which purpose this has a base plate 41 which is supported on the end wall 43 or an annular projection 43 ′ present there.
  • This ring projection 43 'stabilizes the connecting wall 43 in this area.
  • the latter has a metal cylinder 52 with an internal thread 53, which can be seen to be many times greater than the thickness of the base plate 41.
  • the metal cylinder 52 projects as far as necessary into the interior of the tubular metal body 12 and is otherwise fully accommodated with an end wall part 52 'in the inner projection 43' of the end wall 43.
  • the hollow metal body 12 is supported very positively on the end wall 43 of the central body 11. The assembly of the metal body 12 with the central body 11 is ensured in that both can be pushed axially together when the metal body 12 is in the opening facing away from the end wall 60 of the cavity 11 'is used.
