DE3000159A1 - Tilt and turn window assembly - has narrow guide rail screwed above draw unit section with lockable extending arm - Google Patents

Abstract

A draw element, led round the four frame corners and force-locked to a ring, is rigidly connectable to metal components mounted in frame-fixed guideways, in furniture on a turning or tilting window, or similar. The element (3,4) is made up from two or more parts, the first having an extension device, with an arm (10) held on a retaining rail (5) and optionally lockable on the window wing (1) by a bolt (21) through the rail. The rail is mounted above this part, and fixable on the wing by screws passing through slots (16-19) in the part. The protruding ends of the part are connectable to the second and any further parts, closing the force-transfer ring. The rail is narrow enough to be mounted in any esp. wooden window with normal rebate, providing firm anchorage.

Description

Hardware for a turn-tilt window

The invention relates to a fitting according to the preamble of claim 1.

A fitting of the generic type is, for example, from DE-OS 20 32 517 became known. With an "endless belt" led around the frame, which at the window manufacturer, as it were, as yard goods from the supply roll onto the window is transferred, a kind of universal fitting is to be created for all window sizes will.

Such a tape from the supply roll now requires that the above Holding rail of an opening device lying on the tape only on the side next to the tape can be anchored on the window sash. The retaining rail must therefore accordingly be wide.

The rebate design is special with plastic or wooden windows largely standardized and does not offer enough space and therefore forces to Special milling.

The object of the invention is therefore to provide a fitting of the generic type to create, in which the holding rail of the display @ rich @@@ @@ @@ hm @ l @@ h @ lten can that they in @ normal rebate formation, especially with wooden windows can be arranged without special milling and firmly anchored to the window sash. A tension band that is sufficiently wide for the transmission of forces should also be used can find.

This object is achieved according to the invention with the identification features of claim 1 solved.

The new concept is therefore that the drawstring in at least two different sections is divided, of which the first section is from Hardware manufacturer perforated according to the special requirements and then the Opening device is permanently assigned, while the second section (or several Parts) can be designed according to other requirements. In particular the second part can be removed from a supply roll as yard goods. Accordingly, it can be uniformly grid-like over its entire storage length be prepunched. So it becomes the previously known principle of the one-piece, all-round one Drawstring in favor of an improved and space-saving training and yet Safe anchoring of the opening device modified, but without the generic Advantages (universality, cheap power transmission element, simplified storage) to give up.

The further developing features of claim 2- lead advantageously to an inevitably correct positioning of the retaining rail according to the with their connected and adjacent corner guide in the frame corner area and thus at the same time also to a further improved anchoring on the window sash.

The invention is illustrated below with reference to one in the drawing Embodiment explained in more detail.

EE shows: FIG. 1 a fitting according to the invention in schematic form simplified representation, FIG. 2 the tension element according to FIG. 1 in plan view.

In Fig. 1, for the sake of clarity, only the upper one on the hinge side Frame corner of a window sash 1 indicated. Around the window sash 1 is a Milled groove 2, in which the fitting parts to be coupled with the tension element 3 and 4, like operating gears and bolts, housed or guided in the known manner are. The type of guidance and the coupling to the tension element can be, for example as shown in DE-OS 24 50 760 shown.

Of importance here is the area of the opening device, which as central element has a support rail 5, which via spacer blocks 6 and 7, and a corner guide 9 is anchored in the rebate groove 2 via the housing 8. As a result their connection with the corner guide 9 is the alignment of the retaining rail 5 in inevitably given the longitudinal direction of the groove. On the holding rail 5 is known an opening scissor mounted, for example consisting of an opening arm 10 and an additional arm 11. The extension arm 10 carries a bearing eye at its other end 12, which is in a bracket to be attached to the frame (not shown) 13 is pivotably mounted.

A first section 3 of the is located below the retaining rail Tension element, which corresponds to the spacer blocks 6, 7 and the other fastening screws 14, 15 for the holding rail 5 with a corresponding number of longitudinal slots 16, 17, 18 and 19 is provided (Fig. 2).

A bolt 21 is riveted to the section 3 by means of two holes 20, the one longitudinal slot 2-2 of the retaining rail 5 penetrates and to it is used to lock the extension arm 10 for the "turning" function on the window sash 1.

The end of the section 3 projects beyond the holding rail 5 in the longitudinal direction and is deflected on the hinge side via the corner guide 9 by about 900 around the frame corner.

This in the aforementioned manner especially the opening device assigned and the penetration of the necessary fastening screws enabling first section 3 is following the corner guide 9 with one end of a second Part 4 of the tension element in the assembled state of the opening device associate. The second part to be removed from a supply roll as piece goods 4 is, for example, pre-punched in the manner of a grid and in a group of holes at the end 23, a coupling block 24 is anchored in a form-fitting manner by means of two pins 25. Included puts the end of the tape on the pin 25 and is fixed by a counter plate 26, the one with a screw 27 also penetrating a hole 23 releasably on the coupling block 24 is held. The coupling block 24 is an extension of the band section 4 a flat mandrel 28 is integrally formed into the barbed out of the band section 3 embossed teeth 29 engage. A sheet steel sleeve 30 gives the necessary guidance and holds the teeth 29 in engagement with the mandrel 28. In the direction of arrow 31, the According to thorn 28.

of the barb-like inclined teeth 29 insert, but not withdraw in the opposite direction, so that one can be brought about quickly and continuously Tape end connection is given. However, the connection is easy if necessary to solve by the sleeve 30 is pushed up. This illustrated tape end connection has the advantage that it enables the tension element to be steplessly tensioned without that parts of the coupling protrude beyond the rebate groove 11 in a disturbing manner.

The remaining ends of the sections 3 and 4 are on one Coupling block 32 is hooked, which has pins 33 and 34 inclined towards one another for this purpose. The pegs 33 engage through holes 23 of the section 4 and the pegs 34 through holes 35 in the left-hand end of section 3.

The part 3 and the removable in any length from the supply roll Part 4 complement each other in the fully assembled state to form an endless tension element and so the advantage of a specialized assembly becomes with the advantage of a hassle-free connected to different window sizes adaptable tension element. Of course you have to the part 4 not.objectively consist of one piece, but can consist of be composed of several pieces of tape. Part 3 can also be assembled be and in particular from a flat rod-like rigid part and one with it coupled flexible part that extends around the corner guide.
