Description

The The invention relates to a mishandling device for the wing a parallel tilt-and-slide door or a parallel tilt-and-slide window. This as a working method or device.

One Hardware system generally has one on the sash Operating lever, which can be positioned differently and in the Flügelfalzraum slidably mounted drive rods moved to appropriate positions. Such a fitting system is commonly referred to as "central closure". The positions are assigned to certain functions of the fitting system, such as locking the wing in its closed position, the transfer of the wing in its tilted position or releasing the locking of the lower end of the wing, so that it is transferred to the parallel parking position and can be moved laterally.

The different positions of the fitting will be according to their function named. In the first functional position is the wing closed and with the associated fixed frame (frame) locked in the closed position. In the second functional position the wing is tiltable relative to the frame unlocked. In the third functional position finally is the wing opposite the frame so unlocked, that it can be transferred from the tilted position into a parallel shutdown is and then can be moved laterally.

In order to avoid that the drive rods can be moved over the operating lever with wings in the parallel set - off position, was in the DE 20 2005 13 426 U1 (GU) and the DE 20 2005 13 427 U1 (GU) proposed a mishandling device having a pivotally mounted in a housing at the lower spar of the sash frame locking member which engages in the sliding position of the wing in a recess of an underlying drive rod and locks it against displacement. The locking member is biased by a leaf spring in the direction of its blocking position. A release mechanism provides in response to the movement of the lower wing end relative to the frame (the fixed frame) that when you move this end of the frame, the locking member can swing out and is swung back when pressed against the frame. This locking device is quite complicated in construction and correspondingly expensive to manufacture and has only a backup function.

It are further safety devices for a fitting system parallel sliding tilt sliding doors known, the a pivotable at the lower end of a wing pivot lever, the end is arranged pivotably about its upper end, and a the swivel lever on the frame opposite Have stop element. The pivot lever has a down along its longitudinal direction extending guide slot with a lateral recess. In the slot is one with a Drive rod of a central lock drivable connectable bolt arranged. The pivot lever is from a bolt in the slot releasing position in one the bolt in the lateral recess the slot locking position by cooperation with the pivotable on the frame arranged stop element. This safety device requires for a secure locking of the bolt in the lateral recess a correspondingly wide pivoting of the Pivot lever.

Across from the prior art described above, it is the task of Invention to propose a mishandling device that in its construction easier, safer in function and more in theirs Production is more cost-effective. The same applies to a working method.

These Task is by a mishandling lock for the wing a parallel tilt-slip window or a parallel tilt-and-slide door solved, at its wing frame a central closure is arranged between a first functional position, in the wing is closed and locked, a second one Functional position in which the wing is tilted unlocked is, and a third functional position in which the wing from the tilted position into the parallel position can be transferred is, is displaceable, with a to be arranged on the central closure Bolt and a pivotable about an axis of rotation on the sash to be arranged locking element between a movement of the Bolts together with the central locking blocking first blocking position and a bolt releasing the second release position movable is to tilt and closed casement to rest on a frame while taking the release position and around in the parallel position Flügelrahmen to be detached from the frame and to assume the blocking position, wherein the locking element is designed as a two-armed lever whose Lever arms arranged on opposite sides of the axis of rotation are.

The invention is particularly applicable with conventional fitting systems for parallel tilt sliding sash. Such a system has on the top frame on a sliding guide for sliding elements, on each of which a Ausstellschere is articulated for connection to the upper end of the wing. Below on the frame, it has a running rail for carriages, which is connected in each case via a stay arm with the lower end of the wing. Ausstellschere (s) and Ausstellarm (e) lead the wing in its movement, it is preferred that it is controlled by these arms / shears.

The Hardware system is via a control or operating lever operated, which is usually three selected positions has: In a position (first functional position) stops he closed the wing via the hardware system and locked; when moving to the next position (second functional position), the unlocking of the upper wing end takes place and preferably forcibly pivoting into the tilted position, the lower wing end being by snapping or catching or the like is still held in the rebate area; the latter will be when pivoting the lever to its next position (third functional position) moves, so now the wing moved into the parallel parking position and moved laterally can be.

The Fault lock is preferably in the lower vertical rebate attached to the grand piano. It is oriented in such a way that the locking element when fully closed and at tilted wing directly or indirectly on the frame is applied. Through the contact between the frame and locking element the latter is held in the release position. In this one is the Bolt (as a realization of a projection) and thus the central lock without restriction between the individual functional positions displaceable. The locking element has a Ausschwenkwinkel of a lever arm to the longitudinal extent of the central closure.

Becomes the central lock via the control lever or a other drive in the third working position and the sash brought into the parallel sliding position (Abstell), in which he laterally is displaceable, the contact between the frame and locking element ends, so that the locking element from the release position into a bolt (as a projection) of the central closure blocking position (blocking position) emotional. When moving from the release position to the locked position and vice versa, the locking element performs a pivoting movement around the stationary relative to the sash frame axis of rotation out.

These The axis of rotation is preferably transverse to the direction of movement of the central closure and is located in the outline of the wing (in the "wing plane"). As a result, a pivoting in of a lever arm of the locking element in the movement path of the bolt causes (claim 14) when the Wing is transferred from the tilted position in the parallel position and the locking element as a two-armed lever about the axis of rotation pivoted.

Of the first lever arm of the locking element, preferably the lower, is used the contacting of the frame, while the second Lever arm, preferably the upper, the release or blocking of the Bolzens of the central closure - depending on the position - causes. The blockage is a blockade of a (further) longitudinal movement the projection after, for example, below, so as to act on one side limiting and to leave the other direction free.

Of the second lever arm is preferably formed at the end as a stop, the at a pivoting of the locking element about the axis of rotation to lie in the blocking position in the trajectory of the bolt comes when at least a portion of the stop is in the path of movement. The stop and thus the locking element is preferably such trained to be in the third functional position Bolt swings in the path of movement and thereby prevented is that the bolt from the third functional position corresponding Position corresponding to the first or second functional position Positions (back) can be moved.

By the formation of the locking element as a two-armed lever can Locked bolt already by its slight pivoting safely or released. The mishandling lock is needed in comparison to known from the prior art mishandling devices a small space, which is why their use few restrictions subject. The locking element itself has a simple shape, why it is inexpensive and easy to manufacture, for example as a punched or cast element.

Especially It is advantageous that the sensitivity of the mishandling device through the appropriate configuration of the ratio the lever arms of the locking element with otherwise identical construction can be adjusted individually. So can over the selection Leverage ratio determines whether a lock the bolt even with a small swinging the wing arm or only after a further swinging done.

Another advantage is that the mounting position of the mishandling device and its pivoting depending on the opening state of the wing must be less accurately matched to the position of the central shutter when opening and closing the wing than this in the prior art - where the bolt in a specially for provided recess, the kor relative to the bolt must be positioned directly, intervenes - is required. It is sufficient if it is prevented by means of the locking element and the bolt to be arranged on the central lock that the central lock from the third functional position (parallel adjustable wings) in the first or second functional position (tilted or fully locked wing) can be brought. Unlike the prior art, it is not absolutely necessary that the central closure is completely fixed (in the third functional position). As a result, production, installation and adjustment of the mishandling device are significantly simplified. Another advantage is that even with any occurring wear of the central lock, bolt or locking element the mishandling lock remains functional, since the locking element can be completely pivoted into the path of movement of the bolt due to its geometry and kinematics. Furthermore, malfunctions of the incorrect operation lock due to a possible incorrect positioning of the central closure can be reliably prevented.

To a particular embodiment is the locking element preferably by means of a spring, for. B. a coil spring, coil spring, Leg spring or the like, biased in the locked position. This ensures that the locking element automatically begins to move into its locked position, as soon as the Distance from sash to frame in the area of Misuse lock forms or enlarges. From this pivotal position is the blocking position - limited with the one-sided becomes - also dependent (claim 15).

With Advantage, the locking element has a recess, in particular in Shape of a guide slot or a guide groove, on. This (r) can as a blind slot / blind groove or as a continuous slot / groove be educated. Forming a trajectory for the bolt out, with guide slot / groove in the release position befindlichem latch member congruent with the trajectory the bolt is at the central lock. The guide slot or a surface or edge bounding the recess the locking element is preferably substantially radial to the axis of rotation.

To In another embodiment, the locking element only indirectly arrive at the frame to the plant. At this one can Be arranged stop element, which cooperates with the locking element and it in befindlichem in the closed or tilted position Holds wings in the release position. By a Selection of stop elements of different dimensions the mishandling lock individually to different gap dimensions adaptable between sash and frame.

The arranged on the wing frame stop element can next the positioning of the locking element fulfill other functions. The stop element can together with the locking element a lift-out form, due to the effect of the wing in the tilted position can not accidentally be lifted out of a leadership. For this purpose, preferably, the locking element has a recess on, the one in the tilted position, the stop element preferably has contacting surface. It is also sufficient if said surface does not contact the stop element, but is arranged to this at a small distance, so that a lifting of the wing can be prevented.

A Another function of the stop element may be, together with the Bar element form a camp that at least a portion of the weight located in the tilted or closed position Wing absorbs. For this purpose have the stop element and the locking element contact areas, for example in the form of a Surface of a recess of the locking element, during its pivoting get in contact with the release position from the locked position, whereupon the wing is raised slightly. In this way can roll from to the tilting sash wing fitting system belonging carriage to be relieved, causing their deformation is prevented by the sash weight.

In a particularly easy to install design is the Lock element by means of a pivot axis forming pin this can be arranged pivotably on the sash. The pin can be directly on the sash or on to this fixed Function parts of the central closure, z. B. on a cover strip, to be ordered. It can be used, in particular, when mounting a parallel tilt-and-slide wing, a central closure or an inventive Misuse control on the casement or a functional part of the central lock are preassembled, causing the assembly and Adjustment of the misoperation lock facilitated. Alternatively, you can the pin directly to a cover strip or the like if necessary, be integrally formed. Preferably, it is provided with an internal thread, in which a corresponding fastening screw for pivoting Attachment of the locking element can be screwed.

Preferably, a bearing element is arranged between the pin and the locking element. This can form two, the movement of the locking element about the axis of rotation limiting stops. By using bearing elements of different geometry, there is the advantageous possibility of the pivot angle of the locking element to the respective between wing and frame adjust existing gap geometry, so that always a perfect function of the mishandling device can be guaranteed. Preferably, the movement of the locking element limiting stops (engagement parts) are formed by an engaging in a recess of the locking element cam of the bearing element. Conversely, the bearing element, the recess and the locking element have the cam. The bearing element can be arranged on the pin and in turn carry the locking element. Alternatively, the locking element can be arranged on the journal and in turn carry the bearing element.

Around a pivoting of the bearing element about the axis of rotation - d. H. to avoid the pin - it points to another Proposal of the invention a projection, cam or the like. in a corresponding recess of the sash, the central closure or a cover strip of the central closure intervenes. This in turn benefits the ease of installation, since the bearing element only with the pin or the locking element must be joined together and at a designated Arrangement of these elements on the casement by the intervention of the Projection or cam in the aforementioned recess against rotation is fixed without the need for separate assembly steps are.

Further Features and advantages of the invention will become apparent from the following exemplary description of particularly preferred embodiments based on the figures. Showing:

The misoperation lock 1 Can be used with conventional parallel tilt-and-slide doors and windows. An exemplary window unit 21 is in the 1a shown. It consists of a fixed wing that can not be opened 22 as well as a tiltable and parallel to the fixed wing 22 sliding wings 23 , 1b shows in an enlarged perspective view in the 1a by means of a dashed rectangle marked lower left corner of the wing 23 ,

The wing 23 has a sash 2 on, relative to a normally unopenable frame 3 is movably arranged. The frame 3 can also be part of the festival wing 22 be. The arrangement is made with a conventional fitting system, which is only partially explained in the context of the present description. It has a central closure 4 on that in the area of the fold of the sash 2 is slidably disposed in its longitudinal direction (arrow A). In the illustrated embodiment, the central closure 4 behind a stationary arranged on the casement and provided with corresponding penetrations cover rail 24 arranged. Longitudinal movements are mediated by drive or actuation rails.

The misoperation lock 1 is on the sash 2 with one in the 3 recognizable cones 17 arranged. This is relative to the cover rail 24 attached to this immovable. The center axis of the pin 17 is transverse to the direction of movement A of the central closure 4 and in the wing plane of the wing 23 arranged and forms the axis of rotation 8th the misoperation lock 1 out.

On the cone 17 is a locking element 6 arranged. This has for this purpose a bearing sleeve 25 on, which is provided with a non-recognizable in the figures passage opening. Between the locking element 6 and the pin 17 is a bearing element 9 arranged, by means of a coil spring 7 opposite the locking element 6 is biased, in the locked position. The bearing element 9 owns one in the 3 unrecognizable central recess with which it is on the outer circumference of the bearing sleeve 25 of the locking element 6 sitting. Furthermore, the bearing element 9 a nose 26 on top of the latch element 6 opposite side of the bearing element 9 is provided. The nose 26 engages in a not visible in the figures recess of the cover rail 24 a, so that the relative position of the bearing element 9 to the sash frame 2 through the pin 17 , the bearing sleeve 25 and the nose 26 is clearly defined, such that the bearing element 9 relative to the sash 2 immovable and in particular is not pivotable.

At his the locking element 6 facing side, the bearing element 9 a lead 27 on, in a corresponding recess 28 of the locking element 6 intervenes. The coil spring 7 is the end of the projection 27 also in the recess 28 arranged so that they are the bias of the locking element 6 in its locked position causes (in the 2 B and 2c a turn in a clockwise direction).

At the projection 27 of the bearing element 9 is a cam 11 provided in a bag 10 the recess 28 is arranged. The pocket 10 owns opposite the cam 11 an oversize, so bag 10 and cams 11 two attacks 19 . 20 form, the pivoting of the locking element 6 around the axis of rotation 8th restrict this when it reaches the release or the locked position.

At the opposite the cover rail 24 sliding central lock 4 is a bolt 5 arranged through a corresponding recess 29 the cover rail 24 protrudes into the rebate. The bolt 5 is when the handle is activated 30 as an operating element, causing a shift of the central closure 4 in the direction of arrow A, along with this moves.

The locking element 6 is a two-armed lever with an upper lever arm 15 and a lower lever arm 16 pivotable about the axis of rotation 8th educated. At the upper lever arm 15 has the locking element 6 a guide slot 18 on, which is in befindlichem in the release position locking element - this is in 2 B shown - a recording of the bolt 5 serves. The upper end of the upper lever arm 15 is as a stop 14 for the bolt 5 trained, which will be described later in more detail.

At the lower lever arm 16 of the locking element 6 is a recess 13 with an upper contact surface 31 and a lower contact surface 32 educated. The error control block exemplified in the figures 1 further includes a stop element 12 on that in the area of the recess 13 on the frame 3 is arranged (see 1b ).

The function of the misoperation lock 1 results in particular from the 4 to 7 , 4 shows the location of sash frames 2 and frame 3 to each other in a schematic side view. The wing or wing frame 2 is in the closed position and is thereby through the central closure 4 opposite the window frame 3 (releasably) locked. This is the handle 30 in the in 4 centrally shown, lower position. The one with the central lock 4 connected bolts 5 is in its lower end or dead position, which corresponds to the first functional position. He lies in the lower part of the guide 18 of the locking element 6 , This is located in the 2 B shown release position, ie the radial to the axis of rotation 8th extending guide groove 18 is congruent over the trajectory of the bolt 5 , on which this one at a movement of the central lock 4 will move.

The locking element 6 contacted with his lower lever arm 16 the stop element 12 , By this contact, it is against the bias of the coil spring 7 in the bolt 5 vacant position.

5 shows another state in which the handle 30 pivoted counterclockwise by 90 °. In this position (second functional position) is the sash frame 2 over the central lock 4 as well as not shown fitting units in such a way with the frame 3 connected to the left in 5 shown tilting position can be brought. Opposite in the 4 shown position is the central lock 4 and with it the bolt 5 moved so far up that he out of the guide 18 of the locking element 6 has stepped out. As the sash frame 2 in its lower area continues on the frame 3 abuts, contacted the lower lever arm 16 of the locking element 6 continue the stop element 12 , which is why the locking element 6 still in the release position.

To the wing 23 with the sash 2 opposite the window frame 3 and the festival wing 22 in which a shift enabling parallel position (see 7 To bring, the handle must be 3 continue to turn counterclockwise until it reaches the in 6 has reached shown position. In this position is the central closure 4 together with the bolt 5 in its upper end or dead position (third functional position). In this is the sash frame 2 completely from the frame 3 unlocked and can from the in 6 tilt position shown in the in 7 shown Parallelabstellung be brought.

If the sash frame 2 from the frame 3 is pivoted away, the contact between the lower lever arm begins 16 and the stopper element 12 to solve. The locking element 6 pivots due to the bias of the coil spring 7 from the release position into the bolt 5 locking locking position (in 2c shown). Has it reached this blocking position, its maximum pivot angle, preferably below 30 °, carried out, and then spaced the shorter lower lever arm in the course of Parallelabstellens of the stop element 12 , The stop 14 is still completely in the path of movement of the bolt 5 ,

The pivoting of the lever 15 . 16 is through a system of the cam 11 at the inner stop 20 limited. By the locking element located in the blocking position 6 can the handle 30 only be swung back to its pivoted by 90 ° position. At the latest when this Schwenklage after 7 is reached, the bolt comes 5 at the outer stop 14 of the locking element 6 to the plant, causing further actuation of the handle in the direction of 4 shown blocking position is prevented. Here occurs the one-sided limiting effect.

From the in 7 shown, parallel parked position for a locking of the window this first again in the from the 5 and 6 apparent tilting position are brought in the locking element 6 by contacting the stop element 12 is pivoted from the locked position to the release position. When reaching the tilt position, it has automatically taken the release position in which the stop 14 completely out of the path of movement of the bolt 5 was moved out and the guide groove 18 congruent over the trajectory of the bolt 5 lies, why the wing 23 now completely locked.

The stop element 12 has a lead 33 which is in a recess 13 of the lower lever arm 16 of the locking element 6 intervenes. With appropriate coordination of the shape of the projection 33 and the recess 13 with contact surfaces 31 . 32 they contact each other such that a lift-off and / or at least parts of the weight load of the wing 23 receiving support bearing arises.

To form the camp, the upper bearing surface 31 and the lead 33 coordinated so that the contact surface 31 when closing the grand piano 23 on the lead 33 the stop element 12 touches down while pivoting the locking element 6 at least a portion of the sash weight over the locking element 6 and the stopper element 12 directly on the frame 3 transfers.

To form a lift-out, the lower contact surface 32 on the lead 33 the stop element 12 adjusted so that the contact surface 32 the lead 33 engages under tilted wing and thereby make excavation at least difficult, in particular can be completely prevented.
