Fitting for a sliding leaf of a door or window

0001The invention relates to a fitting for a sliding leaf of a window or a door. This is also when the fitting is described when installed on the wing. The positions of the blade are then interpreted as the corresponding positions of the fitting, which is claimed.

0002Such fittings are known in various embodiments, for. Example 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 track rail is in these fittings downward along the window frame mounted seated on the two carriages with their rollers on which Ausstellscheren are arranged which engage the lower end of the wing, record 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 fixedly arranged at the frame rail.

0003The handling is carried out by a handle arranged on the sash element which is drivingly coupled with the sash mounted (as rebate) rods, which serve for locking and unlocking the blade in its closed position. Several positions of the handle is possible.

0004In these known mountings three different sash positions are controllable: once the closure position of the wing in which it is locked on the frame, the tilting position in which the lower vane end is snapped on the frame, and finally the parallel parked open position in which the wing to is ready lateral displacement. These three wing positions correspond to three different positions of the handle element.

0005However, these three positions have the disadvantage that they in practice, particularly when different people use the fitting, light and often lead to faulty operation or faulty operation.

0006The <patcit id="pcit0003" dnum="EP916794A"><text>EP 916 794</text></patcit> discloses a sliding window, in which a sliding wing along a window frame is movably supported. To move the sliding vanes from a closed position to an open position abtgestellte, a lower scissor assembly is provided which has a movable along a curved guide arm. At the upper end of the sliding panel is guided by individual link.

0007The object of the invention to develop the hardware further developed, that such operating errors and faulty operation are avoided. Also is intended to be achieved simplification in the manufacture and assembly of the fitting.

0008This object according to the invention is solved by the teaching according to Claim. 1 The dependent claims relate to advantageous supplements, but not explicitly necessary features to Claim. 1

0009In the solution according to claim 1 the handle member on the wing associated with only two switching positions, one for locking the wing in its closed position and for its release to the parallel storage position of the wing, from which removed area it can then be displaced laterally (slidable) ,

0010A "normal" tilting position of the wing is no longer controllable via a third handle position. Practice has shown that for the operator safety is greatly enhanced, even when several people have the opportunity to actuation of the fitting.

0011The design of the overall fitting and the coordination of the training of Ausstellscheren and their control elements above and below each other provides a uniform parking and Locking movement of the paddle safely. For this, the carriages with the lower frame spar and the sliders to the upper frame member of the sash are connected in each case via a scissor assembly, wherein the upper Ausstellscheren largely similar to 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 storage position) is ensured.

0012The invention is described below with reference to schematic drawings of a number of embodiments:<ul><li><figref idrefs="f0001">Figure 1</figref> : Shows a front view of the sliding leaf of a window or a door in its locked closed position (<figref idrefs="f0001">Figure 1a</figref>) And (in a half-open sliding position,<figref idrefs="f0001">Figure 1b</figref>).</li><li><figref idrefs="f0002">Figure 2a, Figure 2b</figref> : Shows a plan view (<figref idrefs="f0002">Figure 2a</figref>) The controllable scissor assembly at the lower end of the wing (in the vane closed position<figref idrefs="f0002">Figure 2b</figref>).</li><li><figref idrefs="f0002">Figur 3a, 3b Figur</figref> : Shows in the same representation as <figref idrefs="f0002">2a and 2b</figref> the scissor assembly in the parked and ready shifting (sliding) position of the sash.</li><li><figref idrefs="f0003">Figure 4</figref> : Shows a plan view of the fitting, the controllable unit for displaying the upper end of the blade in the open position.</li><li><figref idrefs="f0003">Figure 5</figref> : In the same representation as <figref idrefs="f0003">Figure 4</figref> Assembly according to the <figref idrefs="f0003">Figure 4</figref> in the wing closed.</li><li><figref idrefs="f0004">Figure 6</figref> : Shows - in vertical section near the front end - the closed wings and the corresponding upper and corresponding lower scissor assembly in the closed position.</li><li><figref idrefs="f0004">Figure 7</figref> : Shows in the same sectional view of the wing and the fitting parts in the displacement prepare (displaceable) open position of the wing.</li></ul>

0013<figref idrefs="f0001">Figure 1</figref> a and 1b show a window or a door in a schematic representation. 1 with its frame and with the frame 2 of the pop sliding wing is designated.

0014At the upper and lower horizontal rail of the sash-frame Gleitbeziehungsweise rails 1b or 1a (in the <figref idrefs="f0003 f0004">Figures 4 to 7</figref> with 41 and 44) ​​referred to the fitting fixed. As usual, are displaceably mounted to the locking and unlocking of the wing, which can be shifted from the 2c of the sliding leaf is arranged on the front vertical rail grip member 3 in both directions along the sash rods.

0015<figref idrefs="f0001">Figure 1</figref> a shows the gripping element 3 in the closing and locking position I and <figref idrefs="f0001">Figure 1b</figref> can be moved laterally in its open position II, in which shut off the wings and in the direction of the arrow. 4

0016The weight of the wing is - added allocated from the lower end of the wing two carriages 6, which it about their rollers on the bottom, fixedly arranged on the frame 1 track 1a (or 44 in - at least in phases of its movements <figref idrefs="f0003">Fig. 4</figref> ff.) carriage 6 is arranged in this scissor 6a is in the <figref idrefs="f0002">Figures 2 and 3</figref> shown in plan view. On the carriage of the raising or pivot arm is articulated with its one end fixed. 8 Its other end is pivotally fixed at 14 to the underside of the lower wing spar. On the carriage a control plate is additionally provided with a control slot sixteenth 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 a bolt 15 slides on one end of a link 20 whose other end is articulated at approximately half the length of the set-8 at this at the 21st In<figref idrefs="f0002">Figure 3a</figref> the bolt 15 is shown in the latching recess of the control slot sixteenth

0017The carriage is shown from the <patcit id="pcit0004" dnum="EP619410A"><text>EP-A 619 410</text></patcit> known. The control of the carriage 6 takes place so that the link 20 attached to the bolt 15 at a pulling movement on the extension arm 8 for Räuminneren out in a stationary manner on the running rail 1a (or 44) block 11 (in<figref idrefs="f0001">Fig. 1</figref> 35, the location at the beginning of the running rail shown) is maintained until the control plate passes through the guide block 11 and the pin 15 engages in 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">Figur 3b</figref> Abstellkurve shown 5 of the wing.

0018In the <figref idrefs="f0003">Figures 4 and 5</figref> the fitting parts of the upper wing portion are shown. The basic structure, the shape and mass as well as the function and control with respect to the corresponding stay scissor assembly in which the lower carriages. It should however be noted that the upper fitting parts do not have to carry the weight of the wing to the extent that as the carriages.

0019Instead of the carriages elongated slide members are above 29 and 29a, which have on their longitudinal sides sliding webs 30a and 30b, or the like., The (corresponding guide grooves in a frame fastened to the guide rail 41 in <figref idrefs="f0001">Fig. 1b</figref> with 1b hereinafter) are slidably guided.

0020The sliding members 29 and 29a are preferably made of plastic. You can, like<figref idrefs="f0003">Figure 4</figref> be arranged apparent formed equal but opposite. In the representation of the figures, it is assumed that the left slider 29 has the directly controllable scissor 28.34. This consists of a articulated on the sliding element 28 and a stay arm articulated to this arm 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 stay scissor assembly 31 thus formed is similar to the controlled at the left carriage 6 at the lower end of the wing. The right slider 29 has only one articulated on the sliding element 29a extension arm 28a.<figref idrefs="f0001">Fig. 1b</figref>) Fixedly arranged guide block 35a is held until it can evade to the side in the recess 26a, thereby enabling the sliding of the sliding element and thus a shifting of the wing.

0021As the <figref idrefs="f0002 f0003">Figures 2 to 5</figref> show the carriages with the lower rail 2a of the sash and the sliding elements 29 are connected to the upper rail 2b each have substantially equal formed Ausstellscheren 6 or 31 in the fitting, which the uniform movement of the whole wing in the utility and the closing ensures.

0022The fitting elements for the upper end of the wing are preferably - as illustrated - designed as a preassembled structural unit. For this purpose, the free ends of the extension arms 28 and 28a of the two fitting units 31 and 31 a to a common rod element articulated at 24 and 24a 33rd The rod member 33 may be inserted into a rail 40 and clamped therein. Furthermore, the two sliding members 29 and 29a interconnected by a further rod element 32 to a moving unit with each other.

0023This 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.

0024From the foregoing description, it is clear that the Ausstellscheren and associated controls of the upper sliding elements and the lower carriages, basically have the same shape, are the same dimensioned and configured for performing a uniform wing movement during 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 for this is about equally be applied to the entire wing during opening and closing on the handle member.

0025In the <figref idrefs="f0004">Figures 6 and 7</figref> the fixed or frame 1, the sash 2 and the top-mounted fitting parts and the assembled lower fitting parts with the fixedly arranged on the frame running and guide rails 44 and 41 are (in <figref idrefs="f0001">Fig. 1b</figref> 1a and 1b) refers (in the closed position of the wing<figref idrefs="f0004">Figure 6</figref>) Or the open sliding position of the wing (<figref idrefs="f0004">Figure 7</figref>) Shown in vertical section perpendicular to the direction of the wing.

0026The 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 a bolt 42 on the steering or control arm 20 is designated. This is used in cooperation with a fixedly arranged on the frame, latch 35 (see<figref idrefs="f0003">figures 4/5</figref>) To block the displacement of the wing during the raising motion 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.

0027A similar locking is also provided for the mounting unit at the upper end of the wing.

0028The fitting substantially increases the operating safety, since the hitherto possible faulty circuits are avoided by the handle member only can occupy two functional positions still and the Flügelschliessstellung and parallel parked, enabling the displacement of the blade open position to run the movements of the upper and the lower vane end uniformly , The manufacture and assembly of the fitting is easier than ever, since many parts are formed substantially the same and are the same functional context. The pre-assembly of the fitting parts at least for the upper wing end greatly simplifies the final assembly of the wings.
