Definitions

  • the present invention relates to a corner joint for metal door and window frames with tilt-and-turn twin opening.
  • window wings are normally divided into those with conventional opening, which turn about a vertical axis which passes through the hinge supporting the wing (turn opening) and those with tilt opening, that is to say, with a horizontal axis of rotation and the mobile part of the fitting producing an opening at the top.
  • Doors and windows with twin opening, both tilt and turn are increasingly found in this sector; however, for this purpose, both the fixed and mobile parts of the fitting must be equipped with a series of accessories (tie rods, rods which limit opening, twin movement handles, etc.) which allow the passage from one configuration to the other following operation of the handle.
  • a component which is always present in conventional windows is the corner joint, located in the top corner on the side opposite the hinge; the corner joint has an external body in the shape of a right-angle, having an internal cavity inside which a steel flexible control strip slides, acting as a transmission element for the movements between the handle and the manoeuvre rods which run along the external upright of the mobile frame.
  • a block which is integral with the said flexible strip and has a connecting pin, which points towards the inside of the frame, designed to engage in a corresponding seat made in the control element or rod below it.
  • the said block Since the corner joint is fitted after assembly of the parts which form the uprights and crosspieces of the frame, the said block has a protrusion on one side only, so that the operator can use it from the outside, flexing and turning it so as to release the block from the relative holding-sliding seat during initial assembly operations in order to attach it to or release it from the other elements which form the drive mechanism.
  • the locking pawl for so-called “intermediate locking” must be attached to an additional accessory which "joins" the corner joint and the control rod which extends from the handle, thus increasing the cost due to the increased number of elements and complex assembly: this being because at the locking pawl which causes locking, the rod which supports the locking pawl must have protrusions on both sides to avoid its unwanted release.
  • the object of the present invention is to overcome the afore-mentioned disadvantages by creating a corner joint which allows the rods to be attached and released with a flexing-turning movement, without compromising the closing seal and without necessitating additional accessories.
  • figure 3 illustrates a conventional corner joint, including an external corner body 1a, in which a flexible strip 20a is inserted and slides, the latter being attached to a block 21a having a protrusion 19a, one side of which may be inserted in the guide on the section of frame (not illustrated).
  • a connecting element 17a with a locking pawl 23a for intermediate locking must be used, having rails 18a on both sides, to prevent any unwanted flexing or turning about the protrusion 19a of the block 21a during closure.
  • Figures 1 and 2 show a corner joint 1 for twin-opening metal frames, which according to the present invention is of the type consisting of an external body 4 substantially shaped as a right-angle, having an internal cavity within which a flexible control strip 8 slides.
  • the strip 8 acts as a transmission element between a vertical upright 11 and an upper crosspiece 12 (indicated schematically only in figure 2) of a mobile frame, for the movements sent from a handle 14 to vertical manoeuvre rods 13 which slide within a guide (not illustrated) envisaged along the upright.
  • a connecting part or block 2 which is integral with the flexible strip 8 and has a protrusion 9 which allows one side of the block 2 to be inserted in the guide, and a connecting pin (not illustrated and represented by its axis X in figure 1), which points towards the inside of the mobile frame and is designed to engage in a corresponding seat made in the control element or rod below it.
  • the connecting element or block 2 When the door or window is opened or closed, the connecting element or block 2, together with the strip 8 connected to it, travels between two limit configurations: open and closed.
  • the block 2 is respectively at a maximum and minimum distance from the external body 4.
  • the bottom of the external body 4 has a projecting section 6 which faces downwards and projects outwards for a value substantially equal to but slightly greater than the corresponding height of a joint section 7 on the connecting element or block 2.
  • the projecting section 6 of the external body 4 fits over the joint section 7 in the closed configuration II and does not fit over it in the open configuration I.
  • the connecting part or block 2 has a locking pawl 3 for intermediate locking.
  • the corner joint 1 may be positioned in at least a first or "open” configuration I, in which the connecting part or block 2 can be turned about the protrusion 9 (for example, in the direction indicated by R in figure 1) and a second or "closed” configuration II.
  • the locking pawl 3 interacts with the striker 5 of the intermediate lock, and the flexing-turning of the control strip 8 is prevented by the interaction of the projecting section 6 with the section of joint 7 which are positioned over one another.
  • the projecting section 6, as shown in figure 1, may have a notch 10 on its bottom edge, designed to allow access to the strip 8 housed in the external body 4 for assembly and/or disassembly in the open configuration.
  • a notch 10 on its bottom edge, designed to allow access to the strip 8 housed in the external body 4 for assembly and/or disassembly in the open configuration.
  • the projecting section 6 may have a substantially "C-shaped" cross-section (section through the upright), so as to strengthen the projecting portion and to better guide the block 2.
