Description

The The present invention relates to a corner drive for doors and Windows, in particular doors and windows with frames of metal, wood or plastics such as PVC.

Currently are in technology for Door and window fittings, the is called of parts and accessories for the Transmission and operating systems for opening and closing of doors and windows to distinguish two different construction philosophies: One for Door and door Metal window frame and another for wooden door and window frames and / or plastics such as PVC.

Currently are the differences in the production of these fittings (usually rods, Contact and deflection elements comprise, which by control units operated with handles) on the different design the door- and window frame profiles.

in the Trap of doors and windows with metal frames, the profile has an open Channel up (usually through a pair of L- or T-shaped profiles formed, which protrude from the bottom of the housing and each other are aligned). The channel acts as a guide and picks up the rods, which slide under the action of the control unit to the closing and contact elements to press (the above the channel protruding and usually attached directly to the rods or in a part with the Rods are made), so that the opening and closing of the Door or of the window becomes.

In the case of doors and windows with frames made of wood, plastic or aluminum and wood, the profile forming the vertical frame part is provided with suitable slots (see 1 showing a solution according to the prior art, with a profile of metal or plastic with a wooden paneling, shown by the dashed line). The slots are open towards the outside and serve to fit a profile P having a main chamber C bounded on the sides by two parallel wings A1 and at the top by two transverse ledges A2 or a narrow section forming an upper supporting surface ,

at the door- or window installation will be a pre-assembled kit in this profile incorporating a control unit consisting of a rack and pinion and pinion device consists (with which then connected a handle is) and some rods that are built into the control unit or associated with it. The rods are in turn displaceable in an oblong disguise similar Carrying element with usually predetermined length installed (larger than the length the vertical frame part and adapted during assembly). These Fairing is positioned on the above upper wing and directly screwed to the profile chamber.

elements to close and operating the frame (usually Contact pins and bolts) are connected to the rods or in a part made with the rods and protrude over the panel, in the latter made suitable openings or slots are to the movement of the operating and closing elements under the effect to allow the rods. These differences in profile design led to two different ones Branches in the manufacture of fittings for the different types the door and window frame. This in turn justified the need for manufacturers and "suppliers / fitters" a large number of different items had to keep in stock, with all the associated costs.

This However, it conflicts with the general requirements of the Today's market for door and window frames with its demand for adaptability and quick assembly with special tools that also allow for automatic attachment the controls are used at predetermined positions can, to eliminate the need for a large number of different fittings to keep in stock (as in the market of metal door and window frames the case).

There is also a growing demand for non-specialized kits (ie Installation kits, not only in metal profiles, but also in profiles for frames made of other materials such as wood and aluminum, wood or plastic can be). This demand is easier to meet if simplified Profile geometry is used, which is available to all on the market Types of door and window frame is the same.

In the endeavor to realize this philosophy and at least to fulfill, develop and construct part of these requirements the patent applicant an operating unit for doors and windows (see patent application BO2003A000312) for attachment to a mobile frame with U-shaped channel for the Arrangement and mounting of the control unit, which is arranged that they are for both types of door and window frame profiles can be manufactured and used. This specification is intended only as an example of the related To mention problems, but without direct influence of the solution in question.

outgoing led by this concept the patent applicant further research in order to produce a "universal" fitting part, that means one Fitting part for Door and door Window frame of the above two types is usable: In particular Fittings for Tilt and turn fittings for door and window frames.

One of which is the corner drive (an example of this for door and window frames is made of metal in patent EP-736,658 of the same patent applicant of patent), which are always found in doors and windows with tilting and rotary wings is installed. This fitting is in the top corner of the frame built-in, on the side facing the hinges, and often at the other two corners (bottom of the page opposite the hinges and on top of the same side of the hinge being detached when the door or the window is opened in tilted position). Usually, rejects this fitting an outer housing in the form of a right angle up and an internal cavity with one inside sliding control rod. The control rod consists of a flexible steel spring band for transmission the movements transmitted from the handle to the vertical actuating rods Be that along the outer vertical part of the movable frame to the configuration of the fittings to change on the horizontal frame parts.

Further, from DE 34 30 897 a device for windows or doors with tilting and rotating wings is known, which includes a corner member which can be mounted on a corresponding corner of the window or the door, and a flexible band which slides in the corner element and as a means for transmitting motion from a vertical Operating rod is used on actuators, which are arranged on a horizontal frame of the window or the door. The vertical operating rod is a one-piece rod which is slidably mounted on the corner element and serves with its projection, which protrudes near the respective corner over the horizontal window or door frame part, for locking the movable frame to the fixed frame of the window.
