Description

The invention relates to a fitting for a sliding sash of a window or a door. This even if the fitting is described in the installed state of the wing. The positions of the wing are then to be interpreted as the corresponding positions of the fitting that is claimed.

Such fittings are known in various designs, for. B. from the DE-C 32 34 677 or the EP-A 619,410 , Generally, in these fittings down along the frame, a running rail mounted on the two carriages sit with their rollers on which Ausstellscheren are arranged, which attack the lower end of the wing, take its weight and settle on the frame. For the upper end of the wing Ausstellarme are provided, which are hinged to sliders, which are guided in a fixedly mounted on the frame rail.

The handling is done by a gripping element arranged on the wing, which is drivingly coupled with in the sash (as a rebate) mounted drive rods, which serve to lock and unlock the wing in its closed position. Several positions of the handle are possible.

In these known fittings three different sash positions are controlled: once the closed position of the wing, in which he is locked on the frame, then the tilted position in which the lower wing end is latched to the frame, and finally the parallel parked open position, in which the wing to lateral shifting is ready. These three wing positions correspond to three different positions of the handle element.

However, these three positions have the disadvantage that in practice, especially when different people operate the fitting, easily and often lead to incorrect operations or errors.

The EP 916 794 discloses a sliding window in which a sliding wing is movably mounted along a frame. In order to move the sliding leaf from a closed position to a parked open position, a lower Ausstellschere is provided which has a movable along a cam guide support arm. At the upper end of the sliding sash is guided over individual handlebars.

It is an object of the invention to further develop the fitting so that such incorrect operations and faulty circuits are avoided. Also, while a simplification in the production and installation of the fitting should be achieved.

This object is achieved according to the teaching of claim 1. The dependent claims are advantageous additions, but explicitly no necessary features to claim 1.

In the solution according to claim 1, the handle element on the wing exclusively assigned two switching positions, one for the locking of the wing in its closed position and one for its unlocking the parallel-Abstellstellung of the wing, from which Abstelllage it can then be moved laterally (can be displaced) ,

A "usual" tilt position of the wing is no longer controlled by a third handle position. Practice has shown that this increases the operating safety considerably, even if several people have opportunity to operate the fitting.

Preferably, the controls of the Ausstellscheren are coordinated and matched to each other to move the wing - while avoiding a tilt - up and down uniform along a Abstellkurve from a closed position in Blendrahmenfalz (space) directly into its sliding position and / or back to its closed position ,

The formation of the overall fitting and the coordination of the training of Ausstellscheren and their control elements above and below each other ensures a uniform shut-off and closing movement of the wing safely. For this purpose, the carriages with the lower frame spar and the sliding elements with the upper frame spar of the casement are each connected via a Ausstellschere, the upper Ausstellscheren largely the lower Ausstellscheren in their training same what the uniform movement of the upper wing end with the lower wing tip between the two Positions (closing and Abstellstellung) guaranteed.

FIG. 7

shows in the same section representation of the wing and fittings in the ready to move (ie: movable). Open position of the grand piano.

FIGS. 1a and 1b show a window or a door in a schematic representation. 1 is the frame and 2 of the frame of the tiltable sash.

At the upper and lower horizontal bars of the frame are a Gleitbeziehungsweise running rail 1b and 1a (in the FIGS. 4 to 7 41 and 44) of the fitting fixedly arranged. As usual, in the sash rebate rods for locking and unlocking the wing are slidably mounted, which can be moved longitudinally in both directions by the disposed on the front vertical spar 2c of the sash grip member 3.

FIG. 1a shows the handle element 3 in the closed and locked positions I and FIG. 1b in its open position II, in which the wing is turned off and can be moved laterally in the direction of arrow 4.

The weight of the wing is - at least in phases of its movements - taken from the lower end of the wing associated two carriages 6, which it via their rollers on the lower, fixed to the frame 1 running rail 1a (or 44 in Fig. 6/7 ) drop. Carriage 6 with this arranged scissors 6a is in the FIGS. 2 and 3 shown in plan view. On the carriage of the raising or pivoting arm 8 is articulated firmly with its one end. Its other end is articulated at 14 at the bottom of the lower wing spar. On the carriage a control plate is further provided with a control slot 16. The latter is aligned parallel to the longitudinal direction of the carriage 6, but has at its one end opposite the slot 16 laterally offset latching recess. In the guide slot, a bolt 15 slides at one end of a link 20, the other end is hinged at about half the length of the stay arm 8 at 21 at this. In FIG. 3a the bolt 15 is received in the recess of the control slot 16.

The shown carriage is from the EP-A 619,410 known. The control of the carriage 6 is carried out so that the bolt 20 fixed to the handlebars 15 in a pulling movement on the extension arm 8 to the interior of the room in a stationary on the running rail 1a (or 44) attached block 11 (in Fig. 1 with 35, located in a position at the beginning of the rail 1a) is held until the control plate passes through the control block 11 and the bolt 15 engages in the recess of the control slot 16 and thus allows the displacement of the carriage as a whole. During the pivoting opening movement of the wing, the in FIG. 3b illustrated Abstellkurve 5 of the wing.

In the FIGS. 4 and 5 the fittings for the upper wing area are shown. The basic structure, the shape and the dimensions as well as the function and control correspond with respect to the Ausstellschere those of the lower carriages. However, it should be noted that the upper fitting parts do not have to absorb the weight of the wing to the extent that the carriages.

Instead of the carriages elongated sliding elements 29 and 29a are provided at the top, the sliding webs 30a and 30b or the like. Have at their longitudinal sides, which in corresponding guide grooves of the window frame attachable slide rail 41 (in Fig. 1b labeled 1b) are slidably guided.

The sliding elements 29 and 29a are preferably made of plastic. You can, like FIG. 4 be seen, the same design, but arranged opposite. In the illustration of the figures, it is assumed that the left sliding element 29 has the directly controllable upper opening shears 28, 34 (as 31). This consists of a hinged to the sliding element Ausstellarm 28 and an articulated with this link or control arm 34, the other end engages with a pin 25 in a corresponding control slot 26 with laterally offset latching recess 26a of the sliding member 29. The thus formed Ausstellschere 31 is similar to the Ausstellschere 6a on the controlled left carriage 6 at the lower end of the wing.

The right sliding element 29a has only one hinged on the sliding element 29a extension arm 28a.

As with the Ausstellschere 6a of the lower carriage 6 also has the corresponding upper Ausstellschere 31 of the upper sliding member 29 on the handlebar 34 has a bolt in a at the beginning of the upper slide rail 41 (1b in Fig. 1b ) fixedly arranged control block 35a is held until it can dodge into the recess 26a to the side, thus allowing the sliding of the sliding element and thus a displacement of the wing.

As the FIGS. 2 to 5 show, in the fitting, the carriages with the lower beam 2a of the sash and the sliding elements 29, 29a with the upper beam 2b connectable. This in each case via the substantially same trained Ausstellscheren 6a and 31, which ensures the uniform movement of the entire wing during the parking and the closing movement.

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

This structural summary of fitting parts significantly facilitates the subsequent installation on the door or window. FIG. 4 shows the fittings in the open position (of the wing), in FIG. 5 they are shown in the closed position.

From the foregoing description it is clear that the Ausstellscheren and the associated controls of the upper sliding elements and the lower carriages have substantially the same shape, the same dimensions and are designed to perform a uniform wing movement during opening and closing.

It should also be noted that it is expedient when mounting the fitting to position the handle element about halfway up the sash, so that when opening and closing the handle element about the required force is about evenly transmitted to the entire wing.

In the FIGS. 6 and 7 are the fixed or frame 1, the sash 2 and the mounted upper fitting parts and the mounted lower fitting parts with the fixed to the frame running and slide rail 44 and 41 (in Fig. 1b 1a and 1b) in the closed position of the wing ( FIG. 6 ) or the open sliding position of the wing ( FIG. 7 ) shown in vertical section perpendicular to the direction of displacement 4 of the wing.

The section is in the range of Ausstellscheren 6a and 31. In the Figures 6/7 the lower runner for the carriages is designated 44 and the tracked wheels of the carriages 43. A bolt 42 is disposed on the handlebar or control arm 20. This serves in cooperation with a fixedly arranged on the frame locking or locking element 35 (see FIG. 1a ) or control block 11 (see Fig. 3a ), the displacement of the wing during the raising movement (curve 5 in Fig. 3b ) until the bolt 42 on the handlebar 20 (corresponds to bolts 15 in FIG. 3a ) enters the laterally offset latching recess of the control slot (see the position in FIG. 3a ) and so on Bolt 42 from its locking in the locking element 11 (= control block 11) freed. Only then is the lateral displacement of the issued wing possible.

A same locking is also provided for the fitting unit at the upper end of the wing.

The fitting significantly increases the operator safety, since the previously possible faulty circuits are avoided by the handle element can take only two FunktionsStellungen and the movements of the upper and lower wing end the wing closing position and the parallel parked, the sliding of the wing enabling open position run smoothly. The production and assembly of the fitting are easier than before, because many parts are substantially the same design and are in the same functional context. The pre-assembly of fittings for at least the upper wing end significantly simplifies the final assembly on the wing.
