Description

FITTING ARRANGEMENT WITH AN EXTENSION DEVICE FOR TILTING-TILTING WINDOWS The invention relates to a fitting arrangement according to the preamble of claim 1.

DE 19718325 C1 discloses an independently acting adjusting device, in which two mutually movable hinge parts are provided. A first hinge part is attached to the frame and a second associated with the wing. About an alignment element wings and frame are brought into a desired position to each other and between the movable hinge parts

Locking elements effectively, which fix the hinge parts to each other. The newly defined position of the hinge parts corresponds to the desired position of the sash and the frame. The locking elements used are form-locking links that act between the hinge parts. The disadvantage here is that a reset of the locking elements can only be done manually and

For example, it is necessary if the wing is not displaced in an undesirable manner via the alignment element, but by a faulty operation or handling relative to the frame. This may be, for example, an object accidentally arranged in the fold area, by which the wing is raised. From EP 2902575 A1 a fitting arrangement has become known which comprises a scissor arm and a scissor arm of an opening device. Of the

The scissor arm supports the scissor arm in a rotational opening position against a crease-shaped face-plate rail and limits the inclination of the tilting position in the tilted position

Scissor arm relative to a scissors cuff. The scissor arm is associated with the scissor cuff and the scissor link in a rotary sliding connection. Of the

Scissor handlebar is assigned to the scissor cuff in a rotary joint. Of the

Scissor handle is provided with coupling means which cooperate in the rotational opening position with complementary coupling means on the scissor arm and determine its relative position to the scissor arm. The scissors link can therefore vary its effective support length relative to the scissor arm in the rotational opening position. As a result of the decoupling of the coupling means in the tilted position, the association of the coupling means occurs again with each actuation of the opening device out of the tilted position. The disadvantage here is that the arrangement of the coupling means does not allow a right and left usability of the jack, but at least restrict the available space through the arrangement on the scissor arm.

The invention is therefore an object of the invention to provide a simple reset, which is ideally cyclic with normal use of the window or door and allows a universal use of the fitting assembly.

To solve this problem, the invention provides in a generic fitting, that is a first of the relatively movable parts of the scissor cuff, and the other of said parts of the handlebar is provided between scissor cuff and handlebar a relatively adjustable for Scherenstulp tab, which having the pivot bearing of the handlebar and which supports an eccentric, which is effective between the scissor cuff and the pivot bearing, wherein the eccentric is force-loaded by a first spring element.

The invention succeeds in ensuring a universal applicability, which can be arranged almost completely in the area of the scissor cuff or below and thus does not claim any rebate space.

A further embodiment provides that the first spring element an abutment on

Scherenstulp has and the second spring element is coupled to a drive rod, which is guided below the scissors and supports an abutment thereto. Thereby, the effect of the eccentric can be controlled via the espagnolette fitting.

In order to maximize the effect of the eccentric with small dimensions, it is provided that the eccentric receives an oval cross-section through two eccentric bellies diametrically opposed to the peripheral surface.

In order to fix the wing with the fitting arrangement in the pivoting opening position in the desired alignment position is provided that in the

Schwenkbereitschaftsstellung the drive rod the first spring element

relaxed second spring element is stretched.

The realignment of the fitting arrangement is achieved in that in the Kippbereitschaftsstellung the second spring element is stretched over the drive rod, which has a provision of the eccentric result. In order to achieve a reliable return of the eccentric is provided that the tab is subjected to force in the tilted opening position of the wing in the direction of the pivotal mounting of the handlebar, so that the eccentric forces through the

Spring elements can be moved. The necessary relative orientation of wing and frame is achieved in a simple manner when the opening device is arranged on a wing, which is brought at least in its pivotal position in and near a surface-parallel alignment of the wing to a fixed frame via an alignment element in a desired position relative to the frame , Further advantageous embodiments will be apparent from the drawings. It shows:

Detail view

Fig. 3, the display device in the views of Figure 2 in a fixed Justage- position and

Fig. 4, the display device in the views of Figure 2 and 3 in one

Tilt ready position of espagnolette fitting. Fig. 1 shows a window 1 consisting of a fixed frame 2 and a pivotable therein both about a vertical axis of rotation 3 and about a horizontal axis of rotation 4 wings 5. The frame 2 and the wing 5 are above an upper

Hinge 6 and a lower hinge 7 connected together.

The embodiment provides that the upper hinge 6 is designed as a so-called scissor bearing, while the lower hinge 7 is designed as a so-called corner bearing. The wing 5 has for locking in the frame 2 a - not shown here - locking fitting, which can be operated via a hand lever 8 on the wing 5. In one execution of the

Lock fitting as Drehkippbeschlag is about the hand lever 8 and the possibility for a pivoting movement about the lower horizontal axis of rotation 4 adjustable. At the upper horizontal wing spar 9 is in this case a

Fastening device with a movable perpendicular to the wing plane extension arm attached to the upper horizontal wing spar 9 with the upper hinge. 6 combines. At the lower horizontal wing spar 10 is between frame 2 and wing 5 a - not visible here - tilt lock effective, so that the lower horizontal wing edge 1 1 is held on the frame 2. In the illustrated

Embodiment is indicated that the frame members of the frame 2 and the wing spars of the wing 5 are not parallel, but by longer

Use, wear od. Like. Have moved to an antiparallel position. This is a between the wing 5 and the frame 2 in

the - indicated - starting position 12 existing distance of the folding surfaces 13,

14 - the so-called rebate air or the chamber dimension 15 - reduced in some areas to a minimum. Therefore, it comes when closing the wing 5, for example, from the rotational position for clamping. Therefore, for example, at the lower horizontal frame member 16, an alignment member 17 is provided with the rebate surface 14 of the wing 5 or a - not shown - position-fixed component such

cooperates, that the originally intended distance of the folding surfaces 14, 13 is adjusted again when closing the wing 5. The alignment member 17 consists in the simplest case of an ascending in the direction of movement on running oblique casserole, which cooperates with the rebate surface 14 of the wing. The wing 5 is replaced by the alignment 17 its original starting position 12, in which the frame and wing spars are parallel to each other. When opening the wing 5, however, the front wing edge 18 sags down again as soon as the rebate surface 14 slips off the alignment member 17. If the wing 5 aligned so far antiparallel that the rebate surface 14 no longer hits the ramp of the alignment 17, the wing 5 can only be immersed in the frame 2 by manually lifting the front wing edge 18. Tilt & turn fittings therefore provide that manual manual on the upper hinge 6

Adjustments are appropriate, which serve to restore the starting position 12.

In the illustrated embodiment, the display device 19 shown in Fig. 2 is attached to the upper horizontal wing spar 9. The Ausstellvorrichtung 19 is part of the Drehkippbeschlages and can be brought via the hand lever 8 in different functional positions. The display device 19 has a

Drive rod 20, which is guided below a scissors-type pulley 21. A Ausstellarm 22 is longitudinally displaceably guided at one end in the scissor arm 21 in a slot 23 and at the other end 24 of the hinge 6 in one - not here shown - assigned manner. For storage on the scissor plate 21 of the stay 22 passes through a rivet 25 a guide piece 26 so that the

Guide piece 26 along the Scherenstulps 21 verschiebar and the extension arm 22 is pivotable about the rivet 25. The extension arm 22 is further connected via a link 27 on the scissor arm 21. For this purpose, the stay 22 is pivotally connected via the rivet 28 to the handlebar 27. The link 27 is in turn associated with a pin 29 of a tab 30 pivotally. The bolt 29 forms the pivot bearing of the handlebar 27 on the scissor arm 21st The tab 30 is displaceable along the scissor-type collar 21 and passes through it in an opening 31. Between the tab 30 and the scissors forend 21, an eccentric 32 is arranged. The eccentric 32 has two eccentric bellies 34, 35 lying diametrically opposite the circumferential surface 33, so that it receives an oval cross-section. In addition, the eccentric 32 has a first arm 36 and a second arm 37, which protrude from partially overlapping openings 31, 38 of the scissor hatch 21 and the flap 30. The arm 36 protrudes beyond the scissor cuff 21, while the arm 37 is immersed below the scissor-type cuff 21 in a fitting receiving groove of the wing 5 and the drive rod 20 engages in a slot 39. In the illustrated neutral position of the eccentric 32, the arm 37 strikes a funnel-like widening

The arm 36 also forms a visible in the installed state of the display device 19 indicator for the position of the eccentric 32. If the arm 36 facing away from the pivot bearing of the link 27 through the pin 29, then the eccentric 32 is in its minimum setting.

The eccentric 32 is subjected to such a force by a first spring element 41 that its eccentric abdomen 35 wishes to step in the direction of the opening edge 42. For this purpose, the spring element 41 engages the arm 37 and causes a corresponding torque on the eccentric 32. The arm 37 engages a second spring element 43, which is relaxed in the neutral position. While the spring element 41 is fixedly assigned to the scissors forend 21 on a bracket 44, the second passes through

Spring element 43 a fixed to the drive rod 20 abutment 45 with a longitudinally guided leg 46th

Due to the above-described arrangement results in the following mode of action. In the position shown in Fig. 2, the stay arm 22 is coupled at its end 24 to the hinge 6. The assignment to the frame-side fixed hinge 6 causes the extension arm 22 is held stationary by the alignment member 17 in a relative orientation of the wing 5, while the scissor plate 21 is moved to the wing 5 relative to the left in Fig. 2. The guide piece 26 compensates for this at the free end of the stay 22. The handlebar 27 is held rigidly by its only pivotable connection to the extension arm 22, whereby the tab 30 is displaced within the opening 31 in the scissors forend 21.

This results in the temporary basic position shown in FIG. 2, in which the wing 5 is held by the alignment element 17. Due to the relative movement, the openings 31, 38 shift and the tab 30 moves in Fig. 2 to the right and takes the position shown in FIG. 3 a. As a result, the eccentric 32 is released and is pivoted as a result of the torque generated via the first spring element 41 in its Spreitzstellung in which the Exzenterbäuche 34, 35 fill the increasing distance 47 between the opening edge 42 and the opening edge 48. This leads to a partial relaxation of the first

Spring element 41 and a tracking of the spring element 43. The eccentric 32 spaced from the opening edges 42, 48 form fit. As a result, the wing 5 is set in its initial length 12 and can be easily opened and rotated

getting closed.

Thus, the adjustment is made again and again, it is provided that the position of the eccentric 32 and thus the setting of the display device 19 and the wing 5 can be reset by adjusting the Kippöffnungsstellung. In the tilt-open position, the wing 5 is fixed to the lower horizontal wing spar 10 on the frame member 16 and thus relieved by the alignment member 17. The setting of the tilt opening position causes a displacement of the drive rod 20 in the position shown in FIG. 4. The guided together with the drive rod 20 abutment 45 leads to a tensioning of the spring element 43. This is so equipped in relation to the first spring element with a larger spring rate, so that the force applied by the second spring element 43 the force of the first

Exceeds spring element 41 in the tilted position. As a result, the spring element 43 exerts a greater torque on the eccentric 32 than the spring element 41, which leads to a rotation of the eccentric 32 in the counterclockwise direction in FIG. Since the wing 5 is relieved of the alignment and aligned, the eccentric 32 takes its respect to the opening edges 42, 48 smallest dimension. It is advantageous that the tab 30 is subjected to a force in the tilted opening position of the wing 5 in the direction of the pivotal mounting of the link 27. This is due to the arrangement of the tab 30, based on the storage points of the

Ausstellarms 22 reached. In the tilt-open position, the opening arm 22, the scissors forend 21 and the handlebar 27 form a triangle, at the corners of the rivet 25, the rivet 28 and the bolt 29 are arranged. The extension arm 22 is due to the

Spreading movement of the wing 5 is spread apart by the scissors forend 21, so that the link 27 is subjected to train and the tab 30 in the direction of the rivet 28 subjected to force. As a result of the exclusively longitudinally displaceable mounting of the tab 30 in the scissor plate 21, the tab 30 is pulled away in the longitudinal direction of the scissors-type cap 21 from the opening edge 42, so that the eccentric 32 is pressure-free. The relief of the eccentric 32 causes the spring element 43 can cause a rotation of the eccentric 32.

Is brought starting from the tilted position of the espagnolette / the drive rod 20 in the rotational opening position, the abutment 45 moves into the position shown in Fig. 3 and the first spring element 41 is due to the relaxed second

Spring element 43, the eccentric 32 from new.

The eccentric 32 sets the flap 30 relative to the scissors fore 21 variable in different positions. The effective length 49 of the display device 19 results from the corresponding position of a coupling device 50 for a hinge part, which is additionally provided with a manual actuator 51 and the position of the bolt 29. The out of the hinge 7, the extension arm 22 and the handlebar 27th as well as the scissor cuff 21 existing support structure is thus adjustable in length 49 by the position of the handlebar 27 on the scissor cuff 21 determining tab 30 and the spreading between tab 30 and scissors 21 eccentric acting eccentric 32.

If the arm 36 indicates that the maximum achievable travel of the eccentric 32 has been reached, a new basic setting can be brought about via the adjusting device 51, which is subsequently kept functional by the arrangement made. In order to prevent unwanted back parting of the eccentric 32, tangential surface sections can be provided on the eccentric bellies 34, 35. LIST OF REFERENCE NUMBERS
