Description

Fittings for windows or doors

Technical field

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

BACKGROUND OF THE INVENTION

The expansion mechanism of this type of window or door leaf is used in particular in that it is rotatable about a vertical axis, the sash and window frames of which are made of extruded plastic or light metal profiles. The expansion mechanism is mounted on the front face of the sash frame and fastened by means of screws.

In this case, the two drive tabs extend through the longitudinal milling of the sash fitting to the region of the guide channel provided on the grooved side of the sash, and there they are displaceable in the guide channel to the rods, which are also provided longitudinally displaceable in the guide interaction with the drive channels.

Due to the angular rotation of the handle by 90 °, the drive tabs are moved towards each other or from one another, which also ensures the opposite movement of the two drive rods.

In such expansion mechanisms, there is always a desire to allow left or right abutment in one embodiment. To change this contact, the housing of the expander mechanism is rotated 180 ° about the axis of rotation of the handle and the pinion.

However, this rotation necessitates a change in the direction of rotation of the handle, so that the two longitudinal tabs, which are generally locked and which are arranged longitudinally displaceable in the same groove of the cover plate, abut one another with their faces.

In the known fitting according to EP 0 491 133 A1, the housing of the expander mechanism is formed symmetrically with respect to a transverse plane which is arranged in the axis of rotation of the handle and the pinion, perpendicular to the direction of movement of the toothed sliders and hence the drive bars. This housing, which has a flat rectangular cross-section, is also formed symmetrically to its longitudinal median plane, which is arranged perpendicular to the aforementioned plane. The longitudinal groove of the cover plate, which keeps the toothed sliders inside the housing, is provided laterally offset relative to the longitudinal center plane of the housing, due to the mounting conditions on the sash frame. Also, the toothed slides, wherein the toothed bar, the base plate and the drive tab are formed in one piece, are arranged symmetrically with respect to a transverse plane which is arranged at the center of the width of the drive tabs and at the center of the length of the toothed bar. In particular, the steel length of each toothed bar is doubled against the desired effective length, which also makes it necessary to extend the guide for the toothed sliders on the housing side to twice the design length of the toothed bars.

The cover plate must be loosened for the adjustment of the bearing direction. Then each toothed piece is lifted out of engagement with the pinion. Thereafter, the toothed pieces are longitudinally displaced against each other in the region of their guide until their entrainment tabs assume a precisely aligned position with respect to each other in which they must be brought into engagement with the pinion again. The cover plate is then replaced. This method of operation requires a very careful method of operation to prevent misalignment of the toothed slides. Such demonstration and assembly processes are necessary, and the housing must have a longitudinal design.

It is also known to use toothed slides suitable for each type of bearing and to exchange them with one another for changing the bearing direction of the spacer mechanisms.

According to DE-P 3 445 170, it is proposed to provide the toothed rails with double-sided toothing and to release the retaining tongues releasably on the toothed slide. The adjustment of the bearing direction is effected by rotating each toothed slide 180 ° about its longitudinal axis and offset while moving the tabs.

In the arrangement according to EP 0 446 5566 A1, each toothed slide is transversely symmetrical and is provided with two bearings for the carrier tongues. To adjust the bearing direction, the toothed sliders are also lifted out of engagement with the pinion and in their guide are adjusted longitudinally with subsequent adjustment of the drive tabs.

Thus, changing the bearing direction of the expansion mechanisms requires, however, releasing the cover plate, detaching the toothed sliders from the pinion and changing the position of the toothed sliders, partly releasably engaging the toothed slides and the pinion, and .

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the disadvantages of known fittings with expanding mechanisms and to provide fittings with expanding mechanisms which do not require any engagement with the housing drive means in order to reconfigure the housing, with compact housing and structural simplification of the drive means.

In order to solve this problem, it is proposed according to the invention that the fitting according to the preamble of claim 1 is formed according to the features of the feature of this claim.

The toothed sliders are formed and housed in the housing such that the tabs are longitudinally displaceable with respect to each other and arranged substantially overlapped in the middle handle position. As a result of this arrangement it is possible to rotate the handle from the intermediate handling position to both opposing end handling surfaces, the path of the longitudinal displacement of the opposing driving tabs being identical, regardless of whether the handle is directed to one end position, for example with the vertical direction of the handle and the free end of the handle facing downward, or whether the free end of the handle is directed upward in the second end handling position. Thus, a corresponding angle of rotation of the handle is provided for each type of abutment facing each other. As a result, when the expansion mechanism is rotated 180 ° about the axis of rotation of the handle and the pinion, when the handle is arranged in the middle manipulation position for adjusting the kind of abutment, the necessary angular rotational movement of the handle is then ensured. After adjusting the desired type of abutment, the region of the pivoting angle of the handle, which is no longer required for the sash control, is blocked, for example by locking the handle, pinion or slide. This locking can also be effected, in particular, by means of a rod assembly arranged in the sash of the sash, i.e. by placing the expander mechanism housing on the front surface of the sash frame, for example also by means of a connecting piece connecting the expander to the drive rods.

The adjustment of the seating type is thus possible without disassembly or assembly of the components of the expanding mechanism and of the grain. In this way, no additional error possibilities, construction costs and even toothed sliders can always be formed in one piece.

Despite the lateral displacement of the tabs relative to the longitudinal median plane of the longitudinal displacement plane of the expander mechanism housing, only two fastening screws provided on the same side of the longitudinal median plane of the housing are sufficient to secure the expander mechanism to the sash frame. Also, the design of the housing is reduced, since the length of the toothed slider of the toothed sliders may no longer correspond to twice the longitudinal displacement path.

In the coupling piece which is provided in the guide channel on the sash side on the grooved surface and whose coupling halves are connected to the drive rods, in its middle handling position of its mounting on the positive and force fixed connection with the driving tongues of both toothed sliders the coupling halves are moved against each other and during the angular rotational movement of the handle, one half of the coupling overlapping the other half of the coupling.

In toothed sliding fittings which are Z-shaped in cross-section and whose base plates arranged differently to the cover plate are of various widths and the width of the longitudinal groove corresponds roughly to the thickness of the driving tongues, it is expedient if the thickness of each driving tongue is transverse longitudinal symmetry adapted to the groove and adjacent lateral intermediate handling position to the space in the transverse because of the overall thickness the thickness of which even up to

At the same time, both roughly half the width of the entrainment walls can be seated.

the plane of the cabinet will remain the tongues in

The demands on the unchanged, both driving tabs correspond to the hitherto used tabs.

Lines on each other against each other easily lean.

and

The guidance of the two toothed movements is improved by the slide during their opposite direction that one of the toothed sliders is provided with a support wall that extends across the bearing plane of the driver tongues and the groove of the other toothed which extends from below the longitudinal wall and the longitudinal slide.

The support grooves are formed in this case within the thickness range of the base plate of the toothed slide.

In order to facilitate the insertion of the tabs in the corresponding longitudinally displaceable half-way of the coupling, which are the guide channel, when the expansion mechanism is provided on the sash frame, the free end of each tab is provided with an insertion chamfer.

If each coupling half is provided with a pin for hanging in the hole of the associated drive rod and the guide walls 1, interfering with the slots of the guide channel, it is advantageous that one of the coupling halves is at least in the bearing area one of the tabs provided with an offset width and that the offset end is guided in a smaller longitudinal recess of the other coupling half.

The free end surface of the offset end of one coupling half engages the limiting wall of the longitudinal recess of the other half in the middle handling position, so that the area of angular rotational movement of the handle is no longer required at no extra cost, after engagement of the pull tabs of the expander. locked by the locking position of both coupling halves.

In order to simplify the connection of the two coupling halves to the wing guide of the sash frame and at the same time to improve the support of the offset end of one coupling half, it is advantageous to have the guide offset end of one coupling half and the other extending below the coupling half laterally from the longitudinal recess; so that the fit is limited by transverse extensions extending through the longitudinal recess. By means of guides and transverse extensions extending over the longitudinal recess of the other coupling half on one side or both sides, the offset end is guided, held and supported from all sides on the other coupling half.

The bearing of the second half parallel to the longitudinal recess of the coupling can be provided with a modified and largely overlapping flange.

It is particularly advantageous to provide the limiting surfaces of each bearing with one notch and to provide each driving tongue in the region and the front surfaces with a narrowed cross-section in a plane parallel to the cover plate, thereby obtaining a sufficiently large force transmission surface.

At the same time, this arrangement makes it possible to make one bearing open in the direction of the opposite bearing. This makes it possible to maintain a low bundle thickness in the receiving area. At the same time, undesired doors and guards are also prevented from the corresponding receptacles by means of intervening slots.

The bearings of the two coupling halves are arranged in the plane of the drive tabs over their entire width, so that they are open on both sides in this plane and so it is possible to introduce the drive tabs of the toothed sliders on the expansion mechanism side on both sides of the coupling pieces.

DETAILED DESCRIPTION OF THE INVENTION

The window of FIG. 1 and 2 consists of a fixed frame 7 and a wing 2, the frame 4 of which is hinged like a hinged wing 2 by articulated hinges 3 on a fixed frame 7, rotatable about an axis of movement formed by hinges 3. On that side of the wing 2 away from the axis of movement, an expanding mechanism 5 with its housing 6 is mounted on the face 12 of the frame 4 and is fastened by means of fastening screws. The housing 6 carries a rotatably mounted handle 7 therein which acts by means of drive rods 8, 9 which are connected to one another by a connecting piece 10 which move against each other and which close or open the wing 2 and the fixed frame 1 with each other.

In FIG. 1 shows the seating on the right side and FIG. 2 seating on the left. The handle 7 of the expander is directed horizontally in the fully retracted position and faces the free end 11 against the axis of movement. This represents the intermediate handling position in which the leaf 2 is unlocked and can thus move about the axis of movement. Dotted is an end position in which the handle 7 is directed vertically and its free end 11 faces downwards. This creates a locked handling position in which the sash 2 is locked against the fixed frame 1.

In FIG. 3 and 4, the fitting structure, in particular the expansion mechanism 5 and the connecting piece 10, can be seen more closely.

In the housing 6 of the expansion mechanism 5, which is surrounded by a cover 13, a neck 14 of the handle 7 is received, which carries a circumferentially toothed pinion 15 which cooperates with a larger width toothed spool 17. they consist of a toothed bar 18, a base plate 19 and a carrier tab 20. The toothed bars 18 extend into the guide 21 of the housing 6, which are arranged along the longitudinal walls in cross-sectional and rectangular and longitudinally arranged housing 6 and engage diametrically opposed circumferential sides. In order to hold the toothed slide 16 17 inside the housing 6, the underside thereof is closed by a releasable cover plate 22 having a longitudinal groove 23 for the passage of the drive tabs 20.

When the spreader mechanism 55 is provided on the wing 2, the tabs 20 cooperate with the bearings 24 of the coupling piece 10, which are mounted longitudinally displaceably in the corresponding guide channel 25 on the grooved surface 26 of the wing 2, in which the drive rods 8, 9 are also provided. the guide channel 25 is part of a hollow profile made of light metal, which forms the frame 4 of the leaf 2.

The connecting piece 10 is formed, as is evident in particular from FIG. 9 and 10, of the two coupling halves 27, 28. Each of the coupling halves 27, 28 has at its end a pin 29 for hanging into the opening 30 of the drive rod 8, 9. Each coupling half 28, 27 is provided with guide walls 31 for engaging the notches of the guide channel 25. The coupling half 28 is on its length, which is arranged above the deposit area i

24, offset to narrower width.

This offset end 32 of the coupling half is provided with laterally projecting guides

33. The bearing 24 is limited by two transverse extensions 34, which on both sides extend over the width of the offset end 32.

The bearing 24 of the second coupling half 27 is provided in a flange 35 which is arranged at such a distance from the guide walls 31 that the bearing area 24 is arranged outside the guide channel 25 when the coupling half 27 is inserted into the guide channel 25. which adjoins the second coupling half 28 is provided above the bearing region 24 and thereby overlapped by the flange 35 the longitudinal recess 36 for the shaped fixed and sliding fit of the offset end 32 of the coupling half 28. The offset end 32 extends through its guide rails and extends beyond its half below the coupling half 27 by the extensions 34 over this half

27 couplings, and it always both sides longitudinal recess 36th transverse to longitudinal sliding direction

the limiting surfaces 38 of the bearing 24 are provided with a notch 39.

In the middle handling position of the unlocking mechanism 5 with the unlocked wing 2 shown in FIG. 1 and 2, respectively in FIG. 5 and 7, the handle 7 is provided in a horizontal plane. The two toothed sliders 16, 17 are opposed to each other, the two side walls 40 of the tabs 20 abutting each other.

The housing 6 is formed symmetrically with respect to the transverse plane G which extends through the pivot axis 41 and the pinion 15 and perpendicular to the longitudinal direction of the housing 6 and the handle thereby perpendicular to the longitudinal movement direction of the toothed slides 16, 17 of the coupling piece 10 and the drive rods 8, 9. Likewise, the housing 6 is symmetrical with respect to the longitudinal median plane L. Also, the toothed sliders 16, 17 are symmetrical with respect to the transverse plane Z, which is perpendicular to said longitudinal feed direction and which passes through the toothed rails and driver tabs 20. are the transverse planes of the two toothed sliders 16, identical in the case of the overlapping arrangement of the carrier tongues

20th

At the same time, transverse planes lie

Z in the transverse plane G.

Starting from the middle handling position of the expansion mechanism 5 of FIG. 5 is ready to mount the right-side seat, as in FIG. For this purpose, the tabs 20 are moved by longitudinal milling 42 in the fitting 43 of the leaf frame 4 and introduced into the seating of the coupling piece 10. This is facilitated by the insert chamfers 44 provided at the free ends of the tabs 20. After the expansion mechanism has been fixed. 5 on the wing 2, the fitting is operable. Therefore, the handle 7 of FIG. 1, rotates 90 ° downward in a clockwise direction. Thus, the pinion-shaped handles 7 are rigidly rotated about a pivot axis 41 and connected to the neck by a toothed slide 16 opposite to one another in FIG.

the longitudinal displacement of the toothed gear moves downwards. This is stopped by the abutment of the front edges of the sliders 16, the toothed sliders and the sliders

16, on the walls of the housing 6. This achieves the final handling position of the handle 7 shown in FIG. 1, shown or marked.

During this change, the tabs 20 which are displaced longitudinally relative to each other, the coupling half 27 with the attached drive rod 8 upwards and the coupling half 28 with the drive rod downwards, thereby locking the frame 1 through the fixed frame.

On retraction of the handle 7, the offset end 32 of the coupling half 28 moves further into the longitudinal recess 36 of the coupling half 27. This movement is limited by abutting the free face 47 of the offset end 32 of the coupling half 28 on the end limiting wall 48 of the longitudinal recess 36 of the coupling half 27. The handle 7 is now again in the middle handling position. The rotation angle limitation is provided with an expansion mechanism mounted on the wing 2 and connected to the coupling halves 27, 28 to 90 °.

If there is to be a change in abutment, the arrangement of the expansion mechanism 5 of FIG.

and 5, for the arrangement of FIG.

7, the expansion mechanism is rotated

5, which is not yet arranged on the wing 2 as a whole about the axis of rotation 41 by 180 °.

In order to reach the end and final maneuvering position with the vertical arrangement of the handle 7 and the free end 11 facing downwards, a 90 ° counter-clockwise rotary angular movement is performed.

This also moves the grippers in the opposite direction as when seated on the right side.

Because the handling tabs of the position can, on the

20, independently of each other moving in the longitudinal translation directions, the handle 7 of the expansion mechanism 5 is in a state where it is not mounted at both end-of-travel positions, i.e. both 90 ° clockwise and clockwise. even by 90 ° for the three clockwise sense, with the drive tabs always having the same offset size, but always in the opposite direction.

After the expansion mechanism has rotated about the axis of rotation 41 by a value

180 °, this is mounted on the cross

2 according to FIG. Second

Now, if the anti-clockwise handle is moved 90 ° downward, the toothed slide 16 is moved upwards and the toothed slide 17 is moved downwards. The end manipulation position is again achieved by abutting the front edges 45 of the toothed slides

17, 16 on the cabinet wall 46

6. The restraint of the return of the handle 7 is again secured by abutting the free face of the coupling half 28 on the end limiting wall of the coupling half 27.

Thus, the expansion mechanism 5 can be used both on the left and right, without releasing the cover plate 22 and changing the construction of the expansion mechanism 5.

The cover plate 22 must already be releasably fastened to the housing, as it has been hitherto, to allow the toothed sliders 16 or the carrier tabs to be changed. The cover plate now has the purpose1 to hold the The parts that are housed in the cabinet 6 and to protect them 1 and from loss. The cover plate 22 does not even need to be modified at all if the toothed sliders 1.6, 17 are mounted with respect to the housing by means of construction measures so that they cannot be lost.

To improve mutual support and to facilitate insertion of the toothed sliders 16, 17 in the manufacture of the expansion mechanism 5, the toothed base 16 has a support wall 49 that extends from the base plate 19 over its side wall 40 which projects into the longitudinal groove 50 of the second toothed slide 17 this toothed slide 17 supports.

Between the handle 7 and / or the pinion 15 and between the housing 6, resilient latching elements can be provided in a known manner, having latching angles of 90 ° in order to lock the handle 7 each time a 90 ° rotational angular movement is performed in the middle handling position. or in the end handling positions by means of a specified holding force, thereby reducing the risk of the uneven intermediate inclined surfaces of the handle 7 deviating from positions of 90 °.
