Abstract

The door or window is hung in a fixed frame about an adjustable axis by a number of hinges, each with one section fixed to the frame and one section to the door or window pane. An adjusting element provides an adjustment movement, at least in the plane of the door or window pane and alters the setting of each hinge with respect to the hinge axis to align the hinged frame inside the fixed frame. The hinge sections can slide against each other by the movement of the adjusting element. One or more independently acting locking elements (37) between the hinge sections fix the hinge pieces with respect to each other and prevents the adjustment movement.

Description

The invention relates to a device for aligning the Wing of a door, a window or the like. Relative to one fixed frame, with sash and frame over a relative to the frame adjustable axis of rotation through Hinge elements are formed at least around a vertical one Axis of rotation are pivotally connected to each other and where Hinge element made of at least two movable relative to each other Hinge parts exist, with a first part stationary in the Frame and a second fixedly assigned to the wing with one at least in the surface-parallel position of sash and frame acting alignment element producing an alignment movement.

Devices are known for adjusting the wing regarding its bearings to the fixed frame by means of Allow actuators. For example, it is from the DE 36 37 077 C1 as well as a number of others Publications known a hinge arm regarding one frame fixed to the frame and fixed contrary to that acting through the weight of the wing Secure the load direction with an adjusting screw.

An adjustment of the wing compared to the fixed The frame can be turned by turning the adjusting screw be caused, which is a relative displacement of the end of the Hinge arm attached coupling piece with respect to the Hinge arm results.

The adjustment is done manually and may have to be repeated at regular intervals as the wing follows some time by loosening the fasteners and by Wear of the bearing components an anti-parallel position to the frame occupies.

Sashes and frames can also have auxiliary devices are aligned with each other, such as the DE 327 608 or also show DE 41 17 407 C2. Are there Devices for aligning the wing on the axis of rotation opposite side of the wing attached that when immersing the sash in the frame with fixed position on Frame-mounted elements interact and align of the wing with respect to the frame.

It is a great disadvantage that such devices only in a certain range of the swing angle of the wing act and in the effective range when immersing the wing in the frame, a constraint in the hinges. Furthermore, such devices are very large Deviations in the situation ineffective or must be caused by special technically complex designs become more flexible because they the components assigned to them do not meet on the frame or find and so cooperation becomes impossible.

The tilt function for turn-tilt sashes is also achieved by this Auxiliary devices adversely affected because the tilt axis is shifted by the auxiliary device.

Another device for aligning the wing opposite the framework is known from DE-OS 20 65 840. at the display device disclosed therein is a downward protruding coupling piece attached with an am Bolt linkage of the wing attached locking bolt interacts, with the dome as the mushroom head pin trained locking pin engages around a fork. The The coupling piece is anti-parallel to the rebate circumferential surface of the wing or the frame aligned and causes at one Displacements of the locking bolt a relative movement of the Wing opposite the frame.

It is a major disadvantage that the orientation of the Wing is not effective in all switch positions of the fitting is, but - depending on the position of the locking bolt Alignment device is overridden.

The object of the invention is therefore a device for Align the wing of a door, a window or the like. in relation to a fixed frame that this independently by normal operation of the wing takes place with a safe storage of the sash on the frame and lock against the alignment movement.

According to the invention, the object is achieved by one or more between the hinge parts automatically acting or acting locking element or locking elements, which fix the hinge parts against each other and lock against the alignment movement, the Hinge parts against each other by the alignment element are movable.

Advantageous embodiments of the invention are the subject of the study of the dependent claims.

A particularly safe and simple design of the Locking elements provides that the locking elements look like Form-locking elements exist, and that the positive-locking elements between each other through the alignment movement removing boundary edges of the hinge parts relocatable are arranged.

A simple design and manufacturing technology Design provides that the positive locking elements from with Wedge-provided actuators exist, the Wedge surfaces lie against each other and the adjusting pieces against each other are arranged displaceable.

This ensures that the alignment element hinge parts shifted against each other be fixed in position and thereby the vertical axis of rotation of the Wing is moved relative to the wing. The wing receives thereby a new orientation compared to the fixed Frame in such a way that the upright and horizontal bars of the wing are almost parallel to those of the frame. A further operation of the wing is therefore easily possible because the locking elements once set and by the Alignment element certain position of the wing with respect to Fix the frame in place.

To reset the locking mechanism by the sash weight Another embodiment is to prevent large wings the invention that the wedge surfaces offset from step-like lying, to an opposite to the alignment movement load direction, almost vertical aligned plan areas exist, the levels by Sections running at an obtuse angle to the plane surfaces are connected. This configuration causes the on Normal forces due to the vertical Flat surfaces are transferred while making an adjustment the wedge surfaces interacting with each other adjusting the Effect form-locking elements.

A particularly simple embodiment provides that one of the Wedge surfaces in one piece with a fixed to the axis of rotation connected hinge frame is formed. This reduces the necessary assembly work considerably.

Alternatively, it can also be provided that the Form-fit elements consist of plate-shaped components and the boundary edges almost perpendicular to Direction of loading.

The invention further provides that the positive locking elements through an energy storage device into which the hinge parts mutually blocking position are brought. This is supposed to any friction or odor acting between the positive locking elements Like. Be overcome.

A preferred embodiment also provides that one of the hinge parts is designed as a hinge arm, the one with a hinge pin forming the hinge axis fixed and at the other end with the wing-fixed hinge part - Angled part is at least longitudinally connected. This Design relates above all to turn and tilt and turn sash commercially available fittings, which subsequently with automatic effective adjustment should be equipped.

Another configuration is possible if one of the Hinge parts is designed as a frame-fixed bearing block, while the second moved by means of the alignment element Hinge part is formed by the bearing pin and when the Positive locking elements via a force accumulator, in particular via a spring are connected.

In this case, the locking or positive locking takes place not on the wing but on the frame, so that the device overall is attached to the frame. With such a Design, it is advantageous that the bearing pin enclosing bearing eyes transverse to the axis of rotation - in the Frame level - are elongated and that the Interlocking elements between the narrow side walls of the Bearing eyes and the bearing pin are arranged. Here too provides an advantageous embodiment that the Narrow side walls and the positive locking elements with adjacent wedge surfaces are provided. A right and such a bearing block can be used on the left, if the two bearing eyes are symmetrical on a base plate are arranged. In this case, the bearing block can be used for both can be used on the right as well as for windows that can be opened on the left.

A particularly simple embodiment of such Bearing block provides that the energy storage device as Tension spring is formed. This can be between the two Form-fit elements lie and be effective between them.

As an alternative to the above, can also be provided that the locking device from a locking device locking against the opening device consists. This also works positively, but prevents it a sliding back of the hinge parts in the position in front of Alignment movement.

As an alternative to the described positive - mechanical effective - locking devices, it is possible that the Locking device from a hydraulic cylinder exists, the inlet valve against the alignment movement blocks and with the alignment movement a media inflow to Cylinder causes.

1 shows a window 1 consisting of a fixed frame 2 and one in it both about a vertical axis of rotation 3 and wings 4 pivotable about a horizontal axis of rotation 5 Frame 2 and the wing 5 are via an upper hinge 6 and a lower hinge 7 connected to each other.

The design provides that the upper hinge 6th is designed as a so-called scissor store, while the lower hinge 7 is designed as a so-called corner bearing. The Wing 5 has one for locking in the frame 2 - here not shown - locking fitting on a Hand lever 8 on the wing 5 can be operated. At a The locking fitting is made of a tilt and turn fitting via the hand lever 8 also the possibility for one Swiveling movement around the lower horizontal axis of rotation 4 adjustable. On the upper horizontal wing spar 9 is in this case, an opening device with a perpendicular to Wing-level movable extension arm attached to the upper horizontal wing spar 9 connects to the upper hinge 6. At the lower horizontal wing spar 10 is between the frame 2 and wing 5 a - not visible here - tilt lock effective so that the lower horizontal wing edge 11 on the frame 2 is held.

In the illustrated embodiment, it is indicated that the Frame spars of the frame 2 and the wing spars of the wing 5 do not run in parallel, but through prolonged use, Wear or the like is shifted to an antiparallel position to have. This is a between the wing 5 and the frame 2nd in the - indicated - starting position 12 existing distance of Folded surfaces 13, 14 - the so-called folded air or the chamber dimension 15 - reduced to a minimum in individual areas. Therefore it comes when closing the wing 5, for example, from the Rotary position for clamping.

Therefore, for example, on the lower horizontal frame beam 16 an alignment element 17 is provided which is in contact with the fold surface 14 of the wing 5 or one - not shown here - fixed Component interacts in such a way that the original intended distance of the folding surfaces 14, 13 at Closing of the wing 5 again. The alignment element In the simplest case, 17 consists of one with an in Equipped with ascending ramp Casserole, which with the fold surface 14 of the wing interacts. The wing 5 receives through the alignment element 17th 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 again, as soon as the fold surface 14 slips off the alignment element 17.

Is the wing 5 aligned so far antiparallel that the Folding surface 14 no longer the run-up slope of the Alignment element 17 hits, the wing 5 can only by manually lifting the front wing edge 18 into the frame 2 plunge.

Tilt and turn fittings therefore provide that on the upper hinge 6 manual adjustment options are attached to the Restore the starting position 12 serve.

Fig. 2 shows an upper hinge assembly 20, which consists of a wing-fixed angle component 21, one movable transversely thereto mounted hinge arm 22, one attached to the end and in front of the frame plane projecting coupling part 23 and a fixed to the frame, fixed on the frame visible surface 24 Bearing block 25, the bearing block 25 and that Coupling part 23 pivotally connected via a bearing pin 26 are.

In the embodiment shown in Fig. 2 one Hinge arrangement 20 is a pure one Rotary fitting, in which only one vertical axis of rotation 3 is provided is. The angle component 21 is fastened in here a fitting groove 27 introduced into the rebate surface 14 Hinge arm 22 is on the pin 28, 29 with the Angle component 21 connected, the pin 29 fixed in the Angle component 21 is anchored and the hinge arm 22 in one Passes through slot 30 and this with a mushroom head 31st guaranteed. The pin 28 is rotatable in the eccentric Angle component 21 is mounted and extends through the angle component 21 in an elongated hole 32 and also has a mushroom head 33. The eccentric mounting of the pin 28 is used for Achieving a greater pressure of the wing 5 on the frame 2, i.e. a shift of the sash level towards the frame level. For this purpose, the oblong hole 30 almost corresponds in its transverse dimension the diameter of the pin 29 so that the hinge arm 22 at Actuation of the pin 28 by an inserted therein Tool engagement 34 around the pin 29 acting as the axis of rotation is pivoted, whereby the wing plane is opposite the Frame level shifted.

The hinge arrangement 20 in the illustrated embodiment also has a manually operated adjusting screw 35 on, which acts in the longitudinal direction of the hinge arm 22. This is with a - not visible - thread at the end of a Actuator 36 in engagement, but on the other hand by their location on the coupling part 23 and over the bearing pin 26 with stationary connected to the frame 2.

An actuation of the screw 35 causes the Hinge arm 22 with respect to the fixed screw 35 lengthways is moved so that the fold surfaces 13, 14 a parallel Able to maintain location. For this purpose, at least the pin 29 arrives an end edge of the slot 30 so that the wing 5 over the Angle component 21 is moved with the hinge arm 22.

Window 1 also shows - not here visible - alignment element 17, which the wing 5 in the closed position - i.e. when immersing the wing 5 in align the frame 2 - in a parallel position. Will the Wing 5 moved or aligned by the alignment element 17 raised, then the angle member 21 is relative to Hinge arm 22 moves until the rebate surfaces 13, 14th stand parallel and the rebate clearance or the chamber dimension 15 in its normal size. Through this alignment movement is also relieved of the hinge arm 22, which, because it is stationary the bearing pin 26 is connected to the frame-fixed bearing block 25, the alignment movement is not carried out. This will make a Form-locking element 37 is free in the area of the adjusting element 36 movable, which on the one hand in the direction of the coupling part 23 pointing recess 38 passes through, but perpendicular to Fold surface 14 is slidably arranged, on the other hand with a wedge surface 39 on a complementary Wedge surface 40 of the actuator 36 abuts.

As shown in FIG. 3 in an enlarged detail of FIG. 2 clearly makes, the form-locking element 37 passes through the common Recess 38 of the hinge arm 22 and the actuator 36 and a, recess 38a in the angular component 21.

The almost vertical back of the form-locking element 37 lies at least in the area of the recess 38a of the Angular component 21 in a form-fitting manner on this.

To the contact surface of the form-locking element 37 on the Angle component 21 is enlarged with a recess 38a Aligned at the end with the vertical leg 46.

As already described, is the alignment element 17 Alignment movement of the angular component 21 in the direction R, the positive locking element 37 is free to an extent that corresponds to the amount in which the front - not visible here Wing edge 18 is raised. The tension spring 41 Form-locking element 37 pulled down so that - according to the wedge effect - the new, spread position of the Hinge arm 22 adjusts with respect to the angle component 21. The next time you open wing 5, it will be called Locking element acting form-locking element 37 against the Direction R loaded, it being a form fit between the Angle component 21 and the hinge arm 22 and this to each other, against the direction R of the alignment movement, in Load direction fixed, i.e. locked. In the R direction the lock can still be released.

4 shows the hinge arrangement 20 corresponding to FIG. 3, where the automatic alignment has already taken effect. How is particularly visible in connection with Fig. 3, by the immersion of the positive locking element 37, the relative position of the Hinge arm 22 changed with respect to the angle component 21, see above that the distance between two arbitrarily chosen points on each Component - here based on the fold surface 14 and the Boundary edge 42 'of the actuator 36 shown - changes.

3 and 4 also show that the tension spring 41 at one end the form-locking element 37 engages and on the opposite End receives an abutment on a pin 42. Should For example, the automatic adjustment is withdrawn through a hole 43, a tool 44 or Similar introduced and the positive locking element 37th against the tension spring 41 are moved up and a Desired alignment position of the wing 5 with respect to the frame 2 can be reset with the adjusting screw 35. Both the Set screw 35 and the opening 43 are only in open state of the wing 5 accessible.

The positive locking element 37 can - as shown in FIG. 5 - also by a plug 45, which is seated in the opening 43, fixed become. This is for example when assembling the Hinge arrangement 20 makes sense to the adjustment range of automatic adjustment. The plug 45 protrudes through the leg 46 of the angle component 21 and touches with its lateral surface 47 the lower end 48 of the Form-locking element 37 in its initial position. The stopper 45 According to this configuration, it is only after the wing 5 is installed removed on the frame 2 from the opening 43, so that the Form-locking element 37 only becomes movable.

Fig. 6 shows the form-locking element 37 in an enlarged Scale. The form-locking element 37 has a wedge shape the stepped shoulders 50 are arranged. Through this Arrangement of the step-shaped paragraphs 50 is achieved in that a load acting in the R direction, the flat surfaces 51 almost are loaded vertically and none form-locking element 37 perpendicular to the R direction and counter to the F direction resulting force component arises when heavy Wings 5 an escape of the positive locking element 37 upwards - opposite to direction F - could cause. The depth 52 of paragraphs 50 determines the minimum possible measure with which the alignment movement of the alignment element 17 can be fixed can. The smaller this depth 52 is chosen, the finer Alignment movements can be fixed and retained.

To shift the flat surfaces 51 lying opposite one another to facilitate, the flat surfaces 51 by obtuse angles phase-like sections 53 running to the flat surfaces 51 get connected.

7 shows an embodiment of an opening device a tilt and turn window, the as locking elements acting form-locking elements 37 made of plate-shaped components exist in an opening 55 of the actuator 36th lie next to each other in layers. The positive locking elements 37 are loaded on their underside by spring elements. Is the actuator 36 slidably leading and overlapping extension arm 56 by the aligning force in Direction R - together with wing 5 - moves, so overlap the opening 57 in the extension arm 56 and the opening 55 in Actuator 36 partially. If the cover reaches a clear dimension, that is greater than the strength of one of the form-locking elements 37, so this is arranged under the influence of the one below Spring element moved up and locked the Extension arm 56 with respect to that arranged displaceably Actuator 36 against the direction R.

As the extension arm 56 when the - not visible - alignment element acts 17 is powerless, will not be large Spring forces required by the spring elements. Therefore one Design are selected according to Fig. 7a, in which the spring elements consist of spring tongues 58 which are mutually parallel and by a common transverse web 59 are connected and the molded part 60 form. The molded part 60 can be stamped or the like produce a spring steel and is on the actuator 36th attached.

To the maximum movement of the positive locking elements 37 limit, the extension arm 56 - also to avoid the Penetration of the mobility of the interlocking elements 37 impairing dirt - with a thin-walled cover 61 closed. This thin-walled cover 61 can for example from a removable plastic or sheet metal part be formed.

8a and 8b show a schematic Embodiment of the invention in which the Form-locking elements 37 in a fixed position on the frame 2 Bearing block 70 are performed. A tape roll 71 is in Transverse direction fixed with a - not shown - extension arm an opening device or the like connected. It sticks out a cantilever 72 of the tape roll 71 up to the - not here either shown - folding surface 13 of the frame 2. The tape roll 71st engages around a bearing pin 73 which is in an elongated hole Bearing eyes 74 of the bearing block 70 parallel to the frame plane is led. For this purpose, the bearing block 70 has bearing eyes 74, in which the positive locking elements 37 along the central axis of the Bearing pin 73 are performed. The bearing eyes 74 are on one Provide the end with the wedge surfaces 40 to the central transverse axis 75 of the bearing block 70 the wall thickness of the bearing eye 74 enlarge. The form-locking elements 37 are also with Wedge surfaces 39 provided in the opposite direction run so that the bearing pin 73 facing, with a Circular segment 76 provided lateral boundary edges 77 of the Form-locking elements 37 run parallel to the bearing pin 73.

Through the interaction of the wing - not shown here 5 with the alignment element 17, also not shown the rigidly connected in the plane of the wing 5 with this Tape roll 71 together in that enclosed by the tape roll 71 Bearing pin 73 moved in the R. The through the Energy storage device connected in the form of a spring 78 Form-locking elements 37 are free and can under Action of the spring 78 to move towards each other until they move - Due to the wedge surfaces 39, 40 - with the circular segments 76 again on the - moved by the band roller 71 - bearing pin 73 create and its new, through the alignment element 17th caused position, fix or lock.

The illustrated embodiment has compared to the embodiments described above have the advantage that the wing components are left almost unchanged can. Also 15 are attached outside of the air gap Do not adapt devices to the limited space available and can be easily od with a suitable cover cap. Adapt to the optical conditions.

The base plate 79 of the bracket 70 as shown in FIG Recognizing the embodiment is symmetrical with respect to Central transverse axis 75 designed so that the bearing block 70 both for wing 5 opening to the right as well as to the left opening Wing 5 can be used.

Just for the sake of form, it should be noted that this too Example the interacting wedge surfaces 39, 40 of the Form-locking element 37 and the bearing eye 74 with accordingly Flat surfaces 51 running perpendicular to the direction of loading can be provided.

For the sake of form, it should also be pointed out that here too known, manual adjustment devices in the field of Stay scissors still used, e.g. for basic adjustment, can find.

It should also be noted that it is very severe Wings 5 is advantageous if the positive locking element 37 for example according to Fig. 2 to 5 with the vertical back as large as possible on the vertical angle leg 46 des Angle component 21 bears against a tilting or twisting of the Prevent angular component 21.

Therefore, it can also be provided that the angle leg 46 a has an extension projecting into the recess 38 and / or that the interlocking element 37 along the fold surface 14 of the angle leg 46 is guided. This would also do that Moving the form-locking elements 37 relative to the actuator 36 favors.
