Description

FITTING FOR A PARALLEL REMOVABLE AND IN THIS

PARALLEL LOCATION HORIZONTAL MOVABLE WING OF WINDOWS OR DOORS

The invention relates to an energy storage device for a window or a door according to the preamble of claim 1. In particular, the invention relates to a

Device for tilting parallelepiped sliding sash window / door or slit Parallelabstell- sliding sash window / door. In the following, the part to be opened and closed will be referred to as a wing and the part fixed to it as a frame.

The power storage device has the task of supporting the closing movement of the wing to the frame from the parallel setting, a backup in the end position of

Create Parallelabstelllage and allow a controlled parallel opening. This can be used to control the opening speed when opening the sash in the end position of the parallel-shift position and adversely affect forces and impact noises occurring on the fitting. The forces occurring in such a system are dependent on the initial speed and the mass, so that in particular large windows or doors can load the fitting and cause loud stop noises in the Parallelöffnungsendstellung. The large weight of the wing also complicates the closing process from the parallel opening end position. Furthermore, the aim is to ensure by the use of the easy-to-install force storage device to facilitate the closing of the Parallelabstelllage in the applied closed position.

The power storage device may also have the task of forming an additional barrier against the fall of the wing in a gust of wind. As already stated, the invention relates to an energy storage device, which as

Relief and support in the operation of the window or the door of the Parallelabstelllage is inserted into the fitting closure position or Kippöffnungslage the wing. In these applications, fittings are known that over

Espagnolette and corner drives an actuating movement of a

Forward operating lever over more than one or all sides of the wing to effect locking at a plurality of distributed over the wing circumference by closure devices and a Ausstellvorrichtung a Parallelabstell- sliding and / or tilted opening position of the wing against the frame.

In these areas, an increased demand for comfort is increasingly recognizable, which is associated with increased safety awareness. To meet these demands is to increase the functionality of the components of the assembly.

A fitting of this type has already become known from EP 0103725 B1. The known device has a fitting for a means of Ausstellarmen at least

Parallelabstellbaren wing of a window or a door, wherein the one or more lower exhibitor arms are rotatably mounted on the lower wing cross member on the one hand and on a carriage on the other hand, with a releasable locking device for or

Parallel Abstelllage located lower Ausstellarme, which consists of a cooperating with a locking receptacle locking member, wherein the locking device is triggered by the sliding-Schließendbewegung of the wing relative to the fixed frame by means of a slanted stationary stop. To facilitate the closing of the Parallelabstelllage a control arm is loaded in the direction of its locking movement loaded leg spring between a control arm and a stay.

Through these measures, the movement can be supported by the Parallelabstelllage of the wing in the applied closure position. However, a leg spring is provided for this advantageous feature, which in the known device on the pivot bearing of

Connection between the control arm and the extension arm is mounted.

As a result, a lot of space or height is needed, which adversely affects the stability. Furthermore, the leg spring can be attached only with assembly of the individual components. Thus, a subsequent mounting or replacement is possible only with a costly effort by the entire display is replaced. By choosing the leg spring and due to the low available space for the so small designed leg spring, the fitting can be automatically move only for a short adjustment of the Parallelabstelllage in the direction of the adjacent closure position, so that effective relief is not given.

Furthermore, a device from a brochure "HAUTAU ATRIUM SP comfort" of the company HAUTAU is known, the wing of the Parallelabstelllage in the adjoining

Closing position supported. This device is expensive in construction, has a variety of components and is expensive to manufacture. Furthermore, the device requires a lot of space at the same time adversely affects the appearance.

The invention has for its object to provide a device for facilitating and assisting in the operation of the window or the door of a secured Parallelabstelllage in the closed position of the wing to the frame, which is inexpensive and in a simple, fast, safe and precise manner with little space can be mounted and adjusted. To solve this problem is a fitting for a directed by means of Ausstellvorrichtungen from one of the wall opening plane movement out of a closed position, for example, a fixed frame, at least approximately parallel off and in this

Parallel offset position provided in a parallel movement to the wall opening plane horizontally sliding wings of windows or doors. Here, at least one arranged on the lower cross member of the wing display device is supported by a carriage on an opening and / or frame-parallel track and is limited by a respective rotatably mounted Ausstellarms in a parallel parked opening width with a releasable locking device of a control arm. The locking device consists of a cooperating with a locking receptacle locking member and is triggered by the sliding-Schließendbewegung of the wing relative to the fixed frame by means of a fixed abutment, wherein the control arm at one, in particular the closing side Ausstellarm an axis of rotation is hinged forming the locking receptacle on the carriage and the locking member is mounted on the control arm and the fixed abutment cooperates in the sliding-Schließendbewegung with the control arm and wherein the locking receptacle in a extending in the direction of displacement of the wing first slot arm of an angular control slot merges, the second slot arm forms the locking receptacle with its free end.

Advantageously, an energy storage device, preferably consisting of a tension spring, arranged in the Ausstellvorrichtung, and attached at one end near the axis of rotation between Ausstellarm and control arm on the control arm and connected to the other end near a wing-side pivot between the wing and Ausstellarm with the stay , In this case, the force storage device spaced with increasing movement of the wing in the Parallelabstelllage of the components of the display device in the direction of a free operating field and counteracts the movement of the wing, the force storage device exerts a force on the wing in the Parallelabstelllage, which this with movement in the Closing position accelerates. Upon reaching the closed position of the wing, the wing is held in the closed position by the power storage device itself or in conjunction with a concealed and independently of the fitting automatically acting latching snap device.

For ease of design and connection during assembly, the force storage device or tension spring by means of corresponding eyelets at the respective ends releasably connected to the respective extension arm and the control arm projecting pin is positively coupled positively coupled. Preferably, the positive connection of the power storage device or tension spring on the extension arm on the wing-facing visible side and the control arm is mounted on the directed to the lower cross member of the frame side.

A functionally advantageous power transmission and cost-effective production is achieved in that the tension spring designed as a power storage device is a helical spring, wherein the helically wound wire is arranged in the unloaded and loaded state almost completely spaced between the extension arm and the control arm, and wherein the tension spring in the in Closed position of the display device unloaded state between the stay and the control arm is adjacent. With the spring steel material choice of the power storage device or tension spring can high

Be taken loads by the ends are pulled apart, during which builds up energy and stored until the tension spring contracts again and releases the energy controlled.

Due to the simple coupling of the power storage device to the opening device and characterized in that the force storage device or tension spring is designed as a component independently of the fitting, mounting with the jack or, if necessary, a subsequent mounting to the pre-assembled fitting is possible.

In parallel positioning of the sash of the window or the door, the mounted conventional fitting is capable of an unintentional slamming by special guides and

To avoid undercuts in the release device. A secure stop in

Parallel Abstelllage is achieved when in addition the position is subjected to force by the mainspring, with movement of the wing in the Parallelabstelllage the tension spring is tensioned and a locking member in a locking receptacle by the tension spring in a prestressed position securing the release device holds in Parallelabstelllage and with transfer of the wing from the securely held Parallelabstelllage in the adjacent closed position of the wing to the frame, the tension spring occupies a relieving starting position.

In order to meet the requirements of an adjacent closed position of the wing to the frame, especially at high weights of the window or door, the latching snap device consists of a arranged on the frame closure member and arranged on the wing spring-loaded snap device, preferably at the lower cross member the window or the door is arranged, which holds the wing upon reaching the closed position against the frame.

A simple and cost-effective design of the latching snap device is characterized in that the application of force to the latching device is effected by a pressure spring mounted in a housing, which is motion-coupled with a latch.

In addition, it has proven to be advantageous to the function, installation and cost of the fitting that the locking snap connection is independently of the fitting freely acting on the window or door mountable. Depending on the size and weight of the window or door, regardless of the fitting, the latching snap connection can also be mounted several times in order to increase the tightening force if necessary.

Further advantageous embodiments will be apparent from the drawings. It shows:

1 to 6 of the drawing show a window or a door which has a fixedly mounted frame 1 fixedly mounted wings or a fixed door panel 2 and which is also equipped with a movable wing 3. The movable wing 3 can be brought relative to the fixed frame 1 and the fixed wing or door panel 2 from the direction indicated in Figs. 1 and 2 closing position on the one hand in the Kippöffnungsstellung, as shown in Figs. 3 and 4 , In a further embodiment or by other components of the fitting 10, the wing 3 can be compared to the fixed frame 1 and the fixed mounted wing or fixed door panel 2 but on the other hand also parked in a secured parallel

Bring ventilation position or in a parallel parked position, in which case the wing 3 from the region of the through hole 4 of the fixed frame 1 in the horizontal direction in front of the fixed built-in wing or the fixed door panel 2 is displaced, as shown in FIGS. 5 and 6 can be seen ,

So that these four positions of the wing 3 are possible relative to the fixed frame 1 as well as to the fixedly mounted wing or to the fixed door panel 2, a special fitting arrangement, namely a so-called tilting arrangement, is produced between the wing 3 and the stationary frame 1. Parallelabstell- sliding fitting 10 is provided by the or in Figs. 1 to 6 for the sake of simplicity, only the operating handle 5 on the wing 3 and the upper

Ausstellvorrichtung 6 and the lower Ausstellvorrichtung 7 between wings 3 and fixed frame 1 are hinted at.

The upper display device 6 and the lower display device 7 can be designed kinematically similar to each other. But you can also basically get different configurations. In the upper Ausstellvorrichtung 6 must be taken to ensure that their frame-side pivot points in a horizontal sliding guide 8 of FIG. 7 at the upper cross member of the fixed frame 1 constantly engage and a synchronous movement of their extension arms is secured.

The lower display device 7 is in any case designed so that it carries the weight of the movable wing 3 safely while it cooperates with a running rail 9 at the lower cross member of the fixed frame 1.

In the embodiment, it depends mainly on training and operation of, the lower display device 7 comprehensive fitting, in so far as it is the structural and functional design of at least the lower closing side

Ausstellvorrichtung 7 goes.

Both the closure-side and the opening-side lower Ausstellvorrichtung 7 has a stay 1 1, as shown in Figures 7 to 13. Each of these extension arms 1 1 is about a substantially vertical axle 12 of FIG. 8 and FIG. 9

pivoted on a carriage 13 hinged. Both carriage 13 are each provided with two substantially horizontal axes freely rotatably mounted rollers 14 by means of which they are supported according to Fig. 1 to 7 on the running rail 9 of the fixed frame 1 movable parallel to its plane. The extension arm 1 1 has at its other end a pivot bearing 15 which is pivotally connected to a wing 3 fixed to the bearing block 16, as shown in Figure 8 to 13 can be seen.

The support arms 1 1 carrying two carriages 13 are connected to each other, for example via a coupling rod 17 in a fixed connection, which is indicated in Fig. 10 to 13 partially and dash-dotted lines. With the help of this coupling rod 17, the axle bolts 12 and the carriages carrying them 13 of the stay 7 are kept constantly at a constant distance from each other. Also, the pivot bearing 15 of the two Ausstellarme 1 1 therefore engage constant distance from each other on the wing 3, namely in the rigidly fixed thereto

Bearing blocks 16 on. The wing 3, the two carriages 13 with the coupling rod 17 and the two extension arms 1 1 together form a Lenkerparallelogramm. With the help of this parallelogram Lenker the wing 3 can be adjusted transversely to its plane and also transversely to the plane of the fixed frame 1 between the closed position defined by Fig. 10 and the recognizable in Fig. 7 and Fig. 12 Parallelabstelllage, where he also in the Fig. 3 to 4 shown function intermediate positions goes through.

While in the position shown in Fig. 10, the display device 7 readily a movement of the blade 3 from the FIGS. 1 and 2 corresponding closed position in the apparent from Figs. 3 and 4 tilt position is possible, the wing 3 in the Parallel Abstelllage corresponding position of the display device 7 of FIG. 12 are shifted horizontally to the apparent from FIGS. 5 and 6 opening position. Thus, the wing 3 relative to the fixed frame 1 during his

Horizontal displacement always safely in the parallel stacking relative to the fixed frame 1 remains, it is necessary, this Parallelabstelllage at least the two

Ausstellarme 1 1 of the lower display device 7 with respect to the fixed frame 1 or against the guided on the running rail 9 carriage 13 to block by a special locking device 18, which can be seen particularly clearly in Figs. 9 and 12.

On the other hand, by triggering this locking device 18, the blocking of the

Parallel Abstelllage for the opening arms 1 1, however, be automatically canceled as soon as the wing 3 in its horizontal movement, the sliding-Schließendbewegung before

Passage opening 4 is reached, so that it can then reach relative to the fixed frame 1 from the Parallelabstelllage of FIG. 12 in the closed position of FIG. 10.

For simplicity, a locking device 1 8 is provided only between the closing side lower Ausstellarm 1 1 and the wing 3 and the fixed frame 1 or carriage 13, although it would be quite possible, such locking devices 1 8 in the region of both Ausstellarme 1 1 between wing and fixed frame 1 to provide.

Due to the forced interaction of both extension arms 1 1 in the manner of a Lenkerparallelogramms it is sufficient, the releasable locking device 18 only in

Provide area of the closing side Ausstellarms 1 1 between the wing 3 and the fixed frame 1. As is apparent from FIGS. 8 to 13, in this embodiment, a control arm 20 is articulated freely pivotable about an axis of rotation 1 9 at the lower closing side Ausstellarm 1 1 close to the axle 12 of the carriage 13 with one end. The other free end of the control arm 20 carries a guide pin 21, which is preferably designed as a bolt.

The control arm 20 has approximately in the central region between the axis of rotation 19 and the

Guide pin 21, a locking member 22 which passes through a control slot 23 of the locking device 18 from top to bottom. The locking device 18 consists of a guide plate, which is arranged at the end of the closing side carriage 13 with a projecting projection 24 to the closing side vertical beam 25 of the fixed frame 1 pointing to the carriage 13. The control slot 23 has an angular shape and extends from the lug 24 with a first slot arm 26 in the sliding direction 27 of the wing 3, while a second slot arm 28 from the frame 1 in the direction of the wing 3 forms an angle of less than 90 " of the second slot arm 28 forms a lock 29 or latching receptacle for the locking member 22 in parallel storage position according to FIGS. 9 and 12.

Due to the inclination of the second slot arm 28 relative to the first slot arm 26 and the wing plane, a kind of locking lug 30, which prevents the locking member 22 from entering the first slot arm 26, when a force in the vertical direction from the wing 3 in the direction of the frame. 1 attacks. This can be the Y-shaped, from the bottom

Ausstellarm 1 1 and the control arm 20 formed Ausstellvorrichtung 7 do not kink in Parallelabstelllage the wing 3 to the frame 1. Thus, it is also the other Ausstellarmen the Ausstellvorrichtungen 6, 7 not possible zurückzuschwenken to their original position, so that the parallel shut off wing 3 by means of this locking device 1 8 is held securely in its parallel parked position.

In the range of movement of the sliding in its Schließendbewegung

Guide pin 21 of the control arm 20 acts as shown in FIG. 10 to 13 directly with a fixed abutment 31 on the fixed frame 1 and on the running rail 9,

especially at the closing side lower corner, together.

The hinge pair formed by the stay 7 by the extension arm 1 1 and the control arm 20 is actuated by the common axis of rotation 19 as soon as the control projection acting as a control pin 21 of the control arm 20 with the stationary abutment 31 on the fixed frame 1 is engaged. For this purpose, the frame-side has

Abutment 31 an inlet opening 32 to which an in sliding-Schließendbewegung of the wing 3 against the fixed frame 1 bent down curve slot 33 connects, as can be seen in each of Figs. 10 to 1 1. Due to the aspect ratio, the shape and the articulation of the extension arm 1 1 and the control arm 20, the movement characteristic of the engaging at the end of the closing side carriage 13 in the control slot 23 locking member 22 is determined.

The motion characteristic is in indirect dependence on the movement of the

Guide pin 21 is set at the free end of the control arm 20, while this is with the inlet opening 32 and the cam slot 33 of the frame-side abutment 31 in setting and holding engagement.

When resting in the closed position on the fixed frame 1 wing 3 of FIG. 10 is the locking member 22 of the control arm 20 in the end position of the first slot arm 26 of the control slot 23, while the guide pin 21 of the control arm 20 in the fixed frame 1 facing the end of the Curved slot 33 is located on the frame-side abutment 31, as can also be seen in FIG. 10.

Due to the length dimension of the extension arm 1 1 between the axle 12 and the pivot bearing 1 5 and the already explained above active connection of the control arm 20 to the extension arm 1 1 and the locking device 18 is applied in the Parallelabstellbewegung of the wing 3 from the closed position on the fixed frame 1 Position of the wing 3 of FIG. 8 in the position of Parallelabstelllage shown in FIG. 9 controlled a forced movement of the control arm 20, during which the locking member 22 moves longitudinally within the frame-side control slot 23. In this case, the wing 3 shifts during its essentially transverse to the plane fixed frame 1 extending Abstellbewegung along a determined by the extension arm 1 1 and the control arm 20 curve.

As long as shown in FIGS. 9 and 12, the locking member 22 of the control arm 20 in the frame-side

Control slot 23 in the second slot arm 28 and dwells in front of a locking lug 30 and thus has not yet reached the lock 29, the control arm 20 is guided relative to the extension arm 1 1 so that the guide pin 21 almost always in the vicinity of the fixed frame 1 end facing of the cam slot 33 in the frame-side abutment 31 remains. The wing 3 remains fixed by the control arm 20 so relative to the fixed frame 1, that it is securely held against a horizontal displacement from the region of the passage opening thereof. Only when the locking member 22 in the control slot 23 on the detent 29 upstream locking lug 30 (FIG. 9), the control arm 20 is gradually pivoted about the rotation axis 19 on the extension arm 1 1 so that the guide pin 21 of the control arm 20 from the range the fixed frame 1 facing the end of the cam slot 33 passes into the region of the inlet opening 32 of the frame-side abutment 31 and thus can be detached from the frame-side abutment 31.

At this moment, the locking member 22 on the control arm 20 in the lock or

Locking receptacle 29 run. The locking device 18 comes into positive engagement and supports the extension arm 1 1 on the wing 3 and on its bearing block 16 against turning back about its pivot bearing 15 from. Thus, the Parallelabstelllage of the wing 3 is relative to

fixed frame 1 or to the movable rail 9 on the carriage 13 permanently effectively locked. In these areas, an increased demand for comfort is increasingly recognizable, which is associated with increased safety awareness. To meet these requirements, the functional scope of the components of the assembly is to be increased.

For this purpose, an energy storage device 35 for the wing 3 of windows or doors

provided, which cooperates with the display device 7. The power storage device 35 is used as a relief and assistance in the operation of the window or the door of the Parallelabstelllage in the closed position of the wing 3 to the frame 1, wherein the fitting 10 is used as a so-called espagnolette application and via espagnolette and Eckumlenkungen an actuating movement of the

Operating handle 5 on more than one or all sides of the wing 3 passes on to several at the wing circumference distributed locations by locking devices a lock and the Ausstellvorrichtungen 6, 7 a tilting Parallelabstell- shift position of the wing 3 against the frame 1 to effect.

The arrangement leaves unnecessary processing, for example, cutouts on the components of the display device 7. Thus, no additional edges and corners, which lead to a costly production.

According to FIGS. 8 and 9, the power storage device 35 is arranged between the extension arm 1 1 and the control arm 20 almost next to the extension arm 1 1 within a longitudinal section. Due to the fact that the power storage device 35 counteracts and tensions the movement of the blade 3 during the parallel shut-off operation, energy is automatically built up and stored in compliance with the parallel release position, so that the stored force is transferred from the safe 3 with the transfer of the blade 3 Parallelepstelllage in the adjacent closed position of FIG. 2 and FIG. 10 to the frame 1 discharges and causes a support of the closing movement, wherein the force storage device 35 relaxes according to Fig. 8 and Fig. 10 and assumes a relieving starting position.

According to the embodiment of the invention, the display device 7 forms with the

Force storage device 35 is a structural unit, so that an adaptation to different

Length dimensions of the fitting 10 is easily possible. An additional assembly of the energy storage device 35 thus remains off.

According to Fig. 8 to Fig. 13, the power storage device 35 consists of a tension spring and is attached with one end 36 (Fig. 8) near the axis of rotation 19 between the extension arm 1 1 and control arm 20 to the control arm 20 and the other end 37 near one leaf side

Drehlagers 15 between the wing 3 and stay arm 1 1 connected to the extension arm 1 1, wherein the force storage device 35 with increasing movement of the wing 3 in the

Parallel parking position according to FIG. 9 is spaced from the components of the display device 7 and can be converted into a free operating field and counteracts the movement of the blade 3. In this case, the force storage device 35 exerts a force on the wing 3 in the Parallelabstelllage, which accelerates this movement into the closed position, the wing 3 with reaching the closed position shown in FIG. 8 by the force storage device 35 itself or in conjunction with a concealed arranged and independent from the fitting 10 automatically acting snap-latching device 38 of FIG. 10 and FIG. 1 1 is held in the closed position securing.

According to Fig. 9 and Fig. 12, the force storage device or tension spring 35 by corresponding eyelets 41 at the respective ends 36, 37 releasably connected to each of the extension arm 1 1 and on

Control arm 20 projecting pins 39, 40 coupled positively coupled motion. For this purpose, the arranged on the extension arm 1 1 pin 39 is mounted on the wing 3 directed to the visible side and attached to the control arm 20 having pins 40 mounted on the side facing the lower cross member of the frame 1 side. The extension arm 1 1 and the control arm 20 of the stay 7 form a stable position for the

Power storage device 35 both during assembly and functional. With the position of the pins 39, 40, the effective behavior of the energy storage device 35 can be precisely tuned in a simple manner. The distance between the pins 39, 40 in abutting If the distance of the pins 39, 40 to each other greater than the length of the tension spring 35, the tension spring 35 is in the biased position. This will be a direct

Effect generated, whereby the wing 3 is pressed by the tension spring 35 to the frame 1 in the closed position.

Other attachment options for the tension spring 35, such as a clip-on variant, are also conceivable. Not shown but is conceivable if one or both pins 39, 40 is designed as an eccentric pin or are and has a tool engagement for adjustment or have. With the adjustment, bias of the tension spring 35 can be adjusted.

Alternatively, one or more further pins 40 may be provided at a greater distance to the pin 39 on the control arm 20, which cause a gradual increase in the bias.

Preferably, and shown in Fig. 9, the power storage device 35 formed tension spring is designed as a helical spring, wherein the helically wound wire and thus only the effective range of the energy storage in the unloaded and loaded state of Fig. 8 and Fig. 9 almost completely spaced between the stay 1 1 and the control arm 20 is arranged, wherein the tension spring 35 is arranged in the unloaded in the closed position of the display device 7 state between the extension arm 1 1 and the control arm 20 side by side.

The power storage device or tension spring 35 is preferably made of a spring steel wire.

Due to the simple coupling of the power storage device or tension spring 35 to the

Ausstellvorrichtung 7 and in that the tension spring 35 is equipped as a unit independent of the fitting 10, a subsequent mounting to the display device 7, at least in case of need possible.

With tension of the tension spring 35 by the movement of the blade 3 in the Parallelabstelllage, in addition, the locking member 22 is held in the latching receptacle 29 by the tension spring 35 in a prestressed position, so that an accidental Zufallen the

Ausstellvorrichtung 7 from the Parallelabstelllage fails. When transferring the wing 3 from the securely held Parallelabstelllage in the adjacent closure position, takes the Tension spring 35 of FIG. 8 and FIG. 10 a relieving or slightly biased

Starting position on.

The fitting held closed position of the wing 3 to the frame 1 and thus the position with system of the lower cross member of the wing 3 of Fig. 3 and Fig. 4 in a Kippöffnungslage or depending on the design for transfer to a parallel parked

Ventilation, is made possible by the force of the tension spring 35. But supporting additional components can keep the wing 3 after pivoting on the frame 1 in a secure position.

Especially with high weights of the window or the door, it requires such additional components, which are preferably retrofitted and multi-mountable as needed.

Regardless of the display device 6, 7 or the fitting 10 acting, the snap-latch 38 consists of a arranged on the frame 1 closing part 42 and arranged on the wing 3 spring-loaded snap device 43, which is preferably located at the lower cross member of the window or the door, which holds the wing 3 against reaching the closed position against the frame 1, as can be seen from FIGS. 10 to 13.

For the sake of simplicity, the snap device 43 for applying force to a not shown in a housing 44 mounted compression spring, which with a bolt 45th
