EP3440295B1 - Hinge fitting with a check for tilt and turn windows - Google Patents

Description

The invention relates to a fitting arrangement according to the preamble of claim 1.

The FR 2167494 A5 shows a fitting arrangement according to the preamble, in which the opening device for a rotatable and tiltable sash of a window or a door has a scissor cuff fixedly attached to the sash, which is coupled to an opening arm in a rotary / sliding bearing. The extension arm has at the end in a coupling piece a hinge hole for a hinge pin for storage in a frame on the bearing block. A handlebar, which is pivotably mounted on the handlebar and is assigned to the scissor stay in an adjustable bracket, is also effective between the scissor stay and the extension arm. The handlebar is aligned in the rotational position of the opening device parallel to the scissor stay and the extension arm and causes the extension arm to be supported on the forend over the tab. The tab is supported by an eccentric on the scissor cuff and can be secured with a locking screw relative to the scissor cuff. In order to change the relative position of the wing relative to the bearing block, the tab can be moved relative to the scissor stay. To do this, you must first loosen the locking screw and adjust the eccentric accordingly. The locking screw and eccentric are only accessible when the sash is turned and tilted, whereby the masonry makes access more difficult.

From the DE 19718325 C1 shows an independently acting adjustment device in which two mutually movable hinge parts are provided. A first hinge part is attached to the frame and a second is assigned to the wing. The sash and frame are brought into a desired position with respect to one another by means of an alignment element, and locking elements, which fix the hinge parts to one another, act between the movable hinge parts. The newly defined position of the hinge parts corresponds to the target position of the sash and frame. The locking elements used are form-locking elements that take effect between the hinge parts. The disadvantage here is that a The locking elements can only be reset manually and is necessary, for example, if the sash is undesirably displaced relative to the frame not by the alignment element, but rather by incorrect operation or handling. This can, for example, be an object accidentally arranged in the fold area, by means of which the sash is raised.

From the EP 2902575 A1 a fitting arrangement has become known which comprises a scissor arm and a scissor arm of an opening device. The scissor link supports the scissor arm in a rotational opening position against a fold-side faceplate and limits the inclination of the scissor arm relative to a scissor faceplate in the tilted position. The scissor arm is assigned to the scissor stay face plate and the scissor link in a rotary slide connection. The scissor link is assigned to the scissor stay in a rotating connection. The scissor link is provided with coupling means which, in the rotational opening position, interact with complementary coupling means on the scissor arm and determine its relative position to the scissor arm. The scissor link can therefore vary its effective support length in the rotational opening position relative to the scissor arm. By decoupling the coupling means in the tilt position, the coupling means are assigned again each time the opening device is actuated from the tilt position.

The disadvantage here is that the arrangement of the coupling means does not allow the right and left usability of the opening device, but at least limits the available space by the arrangement on the scissor arm.

The invention is therefore based on the object of enabling a simple reset, which ideally takes place cyclically with normal use of the window or the door and which enables universal use of the fitting arrangement.

To achieve this object, the invention provides in a generic fitting that a first of the relatively displaceable parts of the scissor stay and the other of the parts mentioned is the handlebar, whereby between the scissor stay and handlebar is provided an adjustable tab relative to the scissor stay stay, which has the pivot bearing of the handlebar and supports an eccentric, which is effective between the scissor stay and the pivot bearing, the eccentric being acted upon by a first spring element.

The invention thereby succeeds in ensuring universal applicability, which can be arranged practically completely in the area of the scissor stay or below and thus does not require any rebate space.

The first spring element has an abutment on the scissor cuff and the second spring element is coupled to a drive rod which is guided below the scissor cuff and carries an abutment for this. The effect of the eccentric can thus be controlled via the connecting rod fitting.

In order to maximize the effect of the eccentric with small dimensions, it is provided that the eccentric is given an oval cross section by two eccentric bellies diametrically opposite one another on the peripheral surface.

In order to fix the sash with the fitting arrangement in the swivel opening position in the desired alignment position, it is provided that the first spring element is tensioned when the second spring element is relaxed in the swivel ready position of the drive rod.

The reorientation of the fitting arrangement is achieved in that the second spring element is stretched over the drive rod in the readiness for tilting, which results in a resetting of the eccentric.

In order to achieve a reliable resetting of the eccentric, it is provided that the flap is subjected to force in the tilt-open position of the wing in the direction of the pivoting mounting of the handlebar, so that the eccentric can be moved by the spring elements without force.

The necessary relative alignment of sash and frame is achieved in a simple manner if the opening device is arranged on a sash, which is brought into a desired position relative to the frame at least in its pivoting position in and near a surface-parallel alignment of the sash to a fixed frame via an alignment element ,

Fig. 1 shows a window 1 consisting of a fixed frame 2 and a wing 5 pivotable therein both about a vertical axis of rotation 3 and about a horizontal axis of rotation 4. The frame 2 and the wing 5 are connected to one another via an upper hinge 6 and a lower hinge 7 ,

The embodiment provides that the upper hinge 6 is designed as a so-called scissor stay, while the lower hinge 7 is designed as a so-called corner hinge. For locking in the frame 2, the wing 5 has a locking fitting (not shown here in more detail) which can be operated via a hand lever 8 on the wing 5. When the locking fitting is designed as a tilt and turn fitting, the possibility for a pivoting movement about the lower horizontal axis of rotation 4 can also be set via the hand lever 8. In this case, an opening device is attached to the upper horizontal wing spar 9 with a raising arm which is movable perpendicular to the wing plane and connects the upper horizontal wing spar 9 to the upper hinge 6. On the lower horizontal wing spar 10, a tilt lock - not visible here - is effective between frame 2 and wing 5, so that the lower horizontal wing edge 11 is held on frame 2. In the exemplary embodiment shown, it is indicated that the frame spars of the frame 2 and the wing spars of the wing 5 do not run parallel, but have shifted into an antiparallel position due to prolonged use, wear or the like. This means that 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 folding air or the chamber dimension 15 - reduced to a minimum in individual areas. Therefore, when the wing 5 is closed, for example from the rotational position, it jams. Therefore, for example, an alignment element 17 is provided on the lower horizontal frame member 16, which with the fold surface 14 of the Wing 5 or a positionally stable component (not shown here) cooperates in such a way that the originally intended spacing of the folding surfaces 14, 13 is restored when the wing 5 is closed. In the simplest case, the alignment element 17 consists of a casserole which is provided with an ascending slope in the direction of movement and which interacts with the rebate surface 14 of the wing. The wing 5 receives its original starting position 12 through the alignment element 17, in which the frame and wing spars are parallel to each other. When opening the wing 5, however, the front wing edge 18 sinks down again as soon as the folded surface 14 slips off the alignment element 17. If the wing 5 is aligned antiparallel so far that the rebate surface 14 no longer meets the run-up slope of the alignment element 17, the wing 5 can only dip into the frame 2 by manually lifting the front wing edge 18.

Tilt and turn fittings therefore provide that 6 manual adjustment options are attached to the upper hinge, which serve to restore the initial position 12.

In the illustrated embodiment, the in the Fig. 2 Display device 19 shown attached. The opening device 19 is part of the turn-tilt fitting and can be brought into various functional positions via the hand lever 8. The opening device 19 has a drive rod 20 which is guided below a scissor stay 21. An extension arm 22 is guided in a longitudinally displaceable manner in an elongated hole 23 at one end in the scissor stay cover 21 and assigned to the hinge 6 in a manner (not shown here) at the other end 24. For storage on the scissor cuff 21, the deployment arm 22 with a rivet 25 passes through a guide piece 26 such that the guide piece 26 can be moved along the scissor cuff 21 and the deployment arm 22 can be pivoted about the rivet 25. The extension arm 22 is also connected to the scissor stay cover 21 via a link 27. For this purpose, the extension arm 22 is pivotally connected to the handlebar 27 via the rivet 28. The handlebar 27 is in turn pivotally associated with a bolt 29 of a bracket 30. The bolt 29 forms the pivot bearing of the handlebar 27 on the scissor stay 21. The tab 30 is displaceable along the scissor stay 21 and passes through it in an opening 31.

An eccentric 32 is arranged between the tab 30 and the scissor cuff 21. The eccentric 32 has two diametrically opposite on the peripheral surface 33 Eccentric bellies 34, 35 so that it has 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 cuff 21 and the tab 30. The arm 36 protrudes above the scissor cuff 21, while the arm 37 dips below the scissor cuff 21 into a fitting receiving groove of the wing 5 and the drive rod 20 engages in an elongated hole 39. In the neutral position of the eccentric 32 shown, the arm 37 strikes an opening edge 40 of the flap 30 that widens like a funnel. The arm 36 also forms an indicator for the position of the eccentric 32 that is visible in the installed state of the opening device 19 the handlebar 27 facing away from the bolt 29, then the eccentric 32 is in its minimum setting.

The eccentric 32 is so acted upon by a first spring element 41 that its eccentric belly 35 would like to step in the direction of the opening edge 42. For this purpose, the spring element 41 acts on the arm 37 and produces a corresponding torque on the eccentric 32. A second spring element 43 acts on the arm 37, which is relaxed in the neutral position. While the spring element 41 is fixedly assigned to the scissor stay 21 on a bracket 44, the second spring element 43 passes through an abutment 45 fastened to the drive rod 20 with a leg 46 that is guided longitudinally therein.

Due to the arrangement described above, the following mode of operation results. In the in Fig. 2 position shown, the extension arm 22 is coupled at its end 24 to the hinge 6. The assignment to the hinge 6 fixed on the frame causes the extension arm 22 to be held in a fixed position by the alignment element 17 when the wing 5 is relatively aligned, while the scissor stay 21 with the wing 5 is relatively stationary in the Fig. 2 is moved to the left. The guide piece 26 compensates for this at the free end of the deployment arm 22. The handlebar 27 is held rigidly due to its pivotable connection to the extension arm 22, as a result of which the tab 30 is displaced within the opening 31 in the scissor stay cover 21.

It follows from that in the Figure 2 Temporary basic position shown, 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 the Fig. 2 to the right and take the one in the Fig. 3 position shown. As a result, the eccentric 32 is released and is due to the first spring element 41 generated torque pivoted into its spreading position, in which the eccentric bellies 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 positively spaces the opening edges 42, 48. As a result, the wing 5 is set in its initial length 12 and can be rotatably opened and closed without problems.

So that the adjustment is carried out again and again, it is provided that the position of the eccentric 32 and thus the setting of the opening device 19 and the leaf 5 can be reset by adjusting the tilt opening position. In the tilt-open position, the wing 5 is fixed on the lower horizontal wing spar 10 on the frame spar 16 and is thus relieved by the alignment element 17. The adjustment of the tilt opening position causes the drive rod 20 to be displaced into that in FIG Fig. 4 shown location. The abutment 45 guided together with the drive rod 20 leads to a tensioning of the spring element 43. In relation to the first spring element, this is equipped with a higher spring rate so that the force applied by the second spring element 43 exceeds that of the first 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 counterclockwise in the figure. Since the wing 5 is relieved and aligned via the alignment element, the eccentric 32 takes on its smallest dimension with respect to the opening edges 42, 48.

It is advantageous that the tab 30 is subjected to force in the tilt-open position of the wing 5 in the direction of the swivel mounting of the link 27. This is achieved by the arrangement of the tab 30, based on the mounting points of the extension arm 22. In the tilt-open position, the extension arm 22, the scissor stay 21 and the link 27 form a triangle, at the corners of which the rivet 25, the rivet 28 and the bolt 29 are arranged. The extension arm 22 is spread apart by the scissor stay 21 as a result of the opening movement of the wing 5, so that the link 27 is subjected to tension and the tab 30 is subjected to force in the direction of the rivet 28. As a result of the exclusively longitudinally displaceable mounting of the tab 30 in the scissor cuff 21, the tab 30 is pulled away from the opening edge 42 in the longitudinal direction of the scissor cuff 21, so that the eccentric 32 is free of pressure. The Relief of the eccentric 32 causes the spring element 43 to cause the eccentric 32 to rotate.

If the drive rod fitting / drive rod 20 is brought into the rotary opening position starting from the tilted position, the abutment 45 moves into the position shown in FIG Fig. 3 Position shown and the first spring element 41 realigns the eccentric 32 due to the relaxed second spring element 43.

The eccentric 32 variably fixes the tab 30 in different positions relative to the scissor stay 21. The effective length 49 of the opening device 19 results accordingly from the position of a coupling device 50 for a hinge part, which is additionally provided with a manual adjusting device 51 and the position of the bolt 29. The hinge 7, the opening arm 22 and the handlebar 27 and the scissor cuff 21 existing support structure can thus be adjusted in length 49 by the tab 30 determining the position of the link 27 on the scissor cuff 21 and the eccentric 32 which spreads between the tab 30 and scissor cuff 21.

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 actuating device 51, which is subsequently kept functional by the arrangement made.

In order to prevent undesired resetting of the eccentric 32, tangential surface sections can be provided on the eccentric bellies 34, 35.
