Fitting for a sliding leaf of a door or window

The invention relates to a fitting for a sliding leaf of a window or a door. This even if the fitting is described in the installed state on the wing. The positions of the blade are then interpreted as the corresponding positions of the fitting, which is claimed.

Such fittings are available in different versions known z. B. from the <patcit id="pcit0001" dnum="DE3234677C"><text>DE-C 32 34 677</text></patcit> or the <patcit id="pcit0002" dnum="EP619410A"><text>EP-A 619 410</text></patcit>, In general, a running track is in these fittings downward along the window frame mounted, seated on the two carriages with their rollers on which Ausstellscheren are arranged, which act on the lower end of the blade, take the weight and place it on the window frame. Raising arms are provided for the upper end of the wing, which are articulated to sliders which are slidably guided in a frame on the fixed rail.

The handling is carried out by an element located at the wing handle element which is drivingly coupled with the sash mounted (as rebate) rods which are used for locking and unlocking of the blade in its closed position. Several positions of the handle are possible.

In these known mountings three different sash positions are controllable: once the closing position of the sash, in which it is locked on the frame, then the tilted position, in which the lower end of the wing is locked to the window frame, and finally the parallel parked open position in which the wings to is ready lateral displacement. These three wing positions correspond to three different positions of the handle element.

However, these three positions have the disadvantage that they. in practice, especially when several people use the fitting, light and often lead to faulty operation or faulty operation

It is <b>Object of the invention</b>, Then further develop the fitting that such operating errors and incorrect connections avoided. Also to be achieved here a simplification in the manufacture and installation of the hardware.

This object is achieved by the teaching of claim 1 or claim 11th The latter in claim 11 also with reference to all of the dependent claims 1 to 10 (without their respective respect to claim 1). The dependent claims are advantageous supplements, but does not explicitly necessary features to claim. 1

The working process describes claim 13. In it, the mounted state and the work flow is detected.

In the solution according to claim 1 (or claim 11) associated with the grip element on the casement, in particular exclusively two switching positions, a one side for the locking of the wing in its closed position and for its release to the parallel storage position of the wing, from which removed area he then can be moved (displaced is).

A "conventional" tilt the wing is no longer controllable via a third handle position. Practice has shown that for the operator safety is considerably increased, even when several people have the opportunity to actuation of the fitting.

The formation of the overall fitting and the coordination of training Ausstellscheren and their control elements above and below each other ensures a uniform parking and closing of the gate. These are the carriages with the lower frame spar and the sliding elements to the upper frame member of the sash each have a scissor assembly connectable with the upper Ausstellscheren largely resemble the lower Ausstellscheren in their training, what the uniform movement of the upper blade end to the lower end of the wing between the two positions (closing and storing position) 'guaranteed'.

<figref idrefs="f0001"><b>Figure 1a and 1b</b></figref> show a window or a door in a schematic representation. With 1 is the frame and designated 2, the frame of the pop-sliding sash.

At the upper and lower horizontal spar of the frame rails are Gleitbeziehungsweise 1b or 1a (in the <figref idrefs="f0003 f0004">Figures 4-7</figref> with 41 and 44 hereinafter) of the fitting fixed. As usual, drive rods for locking and unlocking of the blade are displaceably mounted in the sash, which can be moved from the on the front vertical rail 2c of the sliding leaf is arranged grip element 3 in both directions along.

<figref idrefs="f0001">figure 1a</figref> shows the gripping element 3 in the closed and locked position and I <figref idrefs="f0001">figure 1b</figref> can be moved laterally in its open position II, in the off the wings and in the direction of the arrow. 4

The weight of the wing - recorded assigned from the lower end of the wing two carriages 6, which is on its wheels on the bottom, on the frame 1 fixedly disposed guide rail 1a (and 44 in - at least in phases of its movements <figref idrefs="f0003">Fig. 4</figref> ff.) carriage 6 with arranged on this scissor 6a in the <figref idrefs="f0002"><b>Figures 2 and 3</b></figref> shown in plan view. At the carriage of the raising or pivoting arm 8 articulated fixed at one end. Its other end is hinged at 14 to the underside of the lower wing spar fixed. On the trolley a control plate is further provided with a control slot 16th The latter is oriented parallel to the longitudinal direction of the carriage 6, however, has a slot opposite the laterally offset locking recess at its one end. In the guide slot slides a pin 15 at one end of a link 20 whose other end is articulated at approximately half the length of the set-8 in this case the 21st In<figref idrefs="f0002"><b>3a</b></figref> is shown in the latching recess of the control slot 16 of the bolt 15th

The carriage shown is from the <patcit id="pcit0003" dnum="EP619410A"><text>EP-A 619 410</text></patcit> known. The control of the carriage 6 so that the attached to the handlebar 20 pin 15 of a train at the extension arm 8 to the space inside out in a fixed position on the running rail 1a (or 44) block 11 (in<figref idrefs="f0001">Fig. 1</figref> shown at 35, the situation at the beginning of the track) is maintained until the control plate the control block 11 passes and the bolt 15 snaps into the latching recess of the control slot 16 and thus allows the shifting of the carriage as a whole. In the corresponding opening movement of the wing in the created<figref idrefs="f0002"><b>3b</b></figref> illustrated Abstellkurve 5 of the wing.

In the <figref idrefs="f0003"><b>Figures 4 and 5</b></figref> the fittings for the upper wing area are shown. The basic structure, the shape and dimensions as well as the function and control with respect to the corresponding stay scissor assembly in which the lower carriages. However, please note that the upper fitting parts do not have to carry the weight of the wing to the extent that as the carriages.

Instead of the carriages elongated slide members are provided above 29 and 29a, which have on their longitudinal sides sliding webs 30a and 30b or the like., The corresponding guide grooves in a guide rail fastened to the window frame 41 (in <figref idrefs="f0001">Fig. 1B</figref> with 1b hereinafter) are slidably guided.

The sliding members 29 and 29a are preferably made of plastic. You can, as from<figref idrefs="f0003">figure 4</figref> seen the same design, but opposite be arranged. In the representation of figures, it is assumed that the left slider 29 has the right controllable scissor 28.34. This consists of a articulated on the sliding element 28 and a deployment arm pivotally connected with this driver or control arm 34, whose other end engages with a bolt 25 in a corresponding control slot 26 with a laterally offset locking recess 26a of the sliding member 29th The scissor assembly 31 is similar to the controlled so formed at the left carriage 6 at the lower end of the wing. The right-hand sliding element 29a has only one articulated on the sliding element 29a extension arm 28a. As with the scissor 6a of the lower carriage 6 also has the corresponding scissor assembly 31 of the upper slider 29 at the handlebar 34 on a bolt, in the one in the beginning of the upper slide rail 41 (1b<figref idrefs="f0001">Fig. 1B</figref>) Fixed the guide block 35a is held until it can escape to the side in the recess 26a, thereby enabling the displacement of the sliding element and thus a displacement of the blade.

As the <figref idrefs="f0002 f0003">Figures 2 to 5</figref> show, in which fitting the carriages with the lower rail 2a of the sash frame and the sliding elements 29 are connected to the upper member 2b each have substantially equal formed Ausstellscheren 6 or 31, which and the uniform movement of the whole wing in the sidings the closing movement ensures.

The fitting elements for the upper end of the wing are preferably - as illustrated - designed as preassembled. For this purpose, the free ends of the extension arms 28 and 28a of the two fitting units 31 and 31a are hinged to a common rod element 33 at 24 and 24a. The rod member 33 may be inserted into a rail 40 and clamped therein. Furthermore, the two sliding members 29 and 29a are interconnected by a further rod element 32 to a moving unit with each other.

This structural summary of the hardware components greatly facilitates the subsequent installation of a door or window. <figref idrefs="f0003">figure 4</figref> shows the fitting parts in the open position of the wing, in <figref idrefs="f0003">figure 5</figref> they are shown in the closed position.

From the foregoing description it is clear that the Ausstellscheren and associated controls the upper sliding elements and the lower carriages have largely the same shape, are equal sized and configured to perform a uniform wing movement when opening and closing. It is also pointed out that it is useful when attaching the fitting to position the handle member about halfway up the sash so that the force required is approximately equally applicable to the whole wing during opening and closing on the grip element.

In the <figref idrefs="f0004"><b>Figures 6 and 7</b></figref> are the fixed or frame 1, the sash 2 and the top-mounted fitting parts and the assembled lower fitting parts with the to the window frame fixed running and guide rails 44 and 41 (in <figref idrefs="f0001">Fig. 1B</figref> with 1a and 1b hereinafter) in the closed position of the wing (<figref idrefs="f0004">figure 6</figref>) Or the open sliding position of the sash (<figref idrefs="f0004">figure 7</figref>) In vertical section perpendicular to the direction shown of the wing.

The section is in the range of Ausstellscheren 6 and 31. In the figures, the lower running rail for the carriages 44 and seated on the rail wheels of the carriages is designated 43rd With 42 a bolt on the handlebar or control arm 20 is designated. This is in conjunction with a fixed on the frame arranged latching or locking element 35 (see<figref idrefs="f0003">figures 4/5</figref>) To block the displacement of the wing during the deployment movement so long until the linkage bolt 15 of the arm 20 enters the locking recess laterally offset of the control slot (see the position in <figref idrefs="f0002">figure 3</figref>) And so the bolt 42 freed from its catch. Only then is the lateral displacement of the flared wing is possible.

A similar locking is provided for the mounting unit at the top of the wing.

The fitting substantially increases the operating safety, since the previously possible faulty operations are avoided by the grip element preferably only able to occupy two functional positions and the movements of the upper and the lower wing end the wings closed and the parallel parked, shifting the wing enabling open position uniformly expire. Also, the manufacture and assembly of the fitting is easier than before, because many parts are formed substantially the same and are in the same functional relationship. The pre-assembly of the fitting parts at least for the upper wing end greatly simplifies the final assembly of the wing.
