EP3266960B1 - Arrangement with a blind frame for storing a wing frame - Google Patents

Description

The invention relates to an arrangement with a frame with a casement frame, which comprises a push rod fitting cooperating with a handle olive, to which at least one locking pin is assigned, which engages in at least one position of the handle olive in a groove open on one side of a locking part fastened to the frame.

Such an arrangement is used, for example, as a window or door, the casement often being fitted with glazing. The push rod fitting can be designed as a rotating fitting or a turning / tilting fitting, so that, depending on the position of the handle olive or the grip piece that is coupled to it in a rotationally fixed manner, the sash frame can be pivoted into an open or tilted position or can be moved into an open or closed position. In order to implement a locking of the push rod fitting in such an arrangement in order to prevent the sash frame from opening, it is known to mount a handle piece provided with a lock. However, such grips have a relatively large design, which is why they are undesirable in various objects.

The not pre-released EP 3 091 151 A1 discloses an arrangement comprising a frame with a casement frame which comprises a push rod fitting which interacts with a handle olive and which is assigned at least one locking bolt which interacts in at least one position of the handle olive with a closing part fastened to the frame. in the Furthermore, the sash frame is designed to hold a bolt which, in a locked position, blocks the locking bolt and in an unlocked position releases the possible change in position of the locking bolt.

For example, a window or a patio door is operated according to the state of the art by means of a handle, through the rotation or pivoting of which a fitting, which is generally designed as a connecting rod fitting, can be brought into its intended positions. In the area of so-called burglar-resistant windows or window fittings or doors or door fittings, the push rod fittings have locking bolts which are designed as so-called mushroom head bolts and which interact with locking parts designed as security locking parts. In this burglar-resistant area, the handle has the further task of securing the push rod fitting against shifting. For this purpose, hardware-locking grips are usually used, e.g. B. connectable handles or handles that can be unlocked via a push button. In the locked state, the handle ensures a fixed position by means of a polygonal pin, in particular a square bolt, which is firmly connected to the connecting rod fitting via a handle olive, for fixing the position of the connecting rod fitting. The push rod fitting cannot be moved by external force acting on the push rod fitting or the handle with conventional lever tools.

Due to the required integration of the locking and operating mechanism in the handle, the design options are severely limited, particularly filigree designs are practically not feasible.

The DE 38 36 976 A1 discloses a push rod fitting for a wing of a window, door or the like, with a handle for actuation a push rod guided in the casement and a lock which can be actuated using a key and which in its locked position blocks the push rod or a locking slide which is connected to it in motion. The imperative to change the push rod fitting proves problematic, so that an assembly of the lock is not possible without the installation of a correspondingly modified push rod fitting.

Furthermore, the DE 20 2008 012 837 U1 a window with a lockable fitting which comprises at least one push rod which extends at least over part of the circumference of the window sash and has and / or actuates locking elements acting between the window sash and a window frame, the push rod being displaceable along an edge of the window sash. At least one locking element is slidably mounted in the window frame transversely to the longitudinal extent of a frame part and can be inserted into at least one locking receptacle recess in the push rod and / or a recess in the window sash. The push rod has a bore which is in a locked position in a congruent position with the bore in the window sash, so that the locking element locking the push rod cannot be inserted into the bore of the push rod.

The invention has for its object to provide an arrangement of the type mentioned, in which securing the position of the connecting rod fitting can also be retrofitted without complex changes to the connecting rod fitting, the securing of the position not having a disruptive effect on the visual impression.

According to the invention the object is achieved by the features of the independent claim.

The subclaims represent advantageous embodiments of the invention.

An arrangement comprises a frame with a wing frame, which comprises a push rod fitting which interacts with a handle olive and to which at least one locking pin is assigned, which engages in at least one position of the handle olive in a groove of a closing part fastened to the frame and which is open on one side, the wing frame for holding a bolt is formed, which in a locked position causes a locking of the locking bolt in the groove of the locking part and in an unlocked position a release for possible change in position of the locking bolt.

If, for example, the locking bolt, which usually has a mushroom head in a security fitting, is in a position in which the sash frame is locked with respect to the frame, the bolt can be placed in a correspondingly positioned opening in the sash frame or the frame, which is perpendicular to the longitudinal extension of the push rod fitting and preferably runs parallel to an outer edge of the casement or the window frame, insert and shift into its locked position, in which the bolt is in the displacement path of the locking bolt and prevents its movement out of the blocked position. Since the locking bolt that is firmly connected to the push rod fitting is blocked in its displacement movement, the push rod fitting cannot be moved either. For example, if an attempt is made in the locked position to twist the handle olive, either by rotating the associated handle or by attacking the side opposite the handle, the bolt in its locked position prevents the locking pin from opening due to the blockage of the locking bolt Casement. For example, it is possible to either place the bolt circumferentially on the locking bolt or to provide the bolt with, for example, a fork-shaped opening in which the locking bolt is held immovably. In the unlocked position, the bolt admits the locking bolt its displacement, which enables the sash to be tilted and / or opened by pivoting or shifting relative to the frame, is free. In this position, the bolt can remain in the associated opening in the casement or frame and only release the path of movement of the locking bolt.

Because of this type of locking of the locking bolt with the bolt in the locked position, the push rod fitting is reliably locked without being weakened through a corresponding opening, as is known, for example, from the prior art. Furthermore, it is possible to arrange the bolt even in the case of an existing casement or window frame, both in the factory and subsequently in the installed state of the window or door.

Since the bolt in its locked position blocks the locking bolt in the groove of the locking part, the locking bolt is held in the groove of the locking part fixedly attached to the frame in a position in which the casement is either locked in the frame or displaceable, i.e. pivotable or is movable. Movement of the locking bolt out of the groove of the locking part is prevented by the bolt in its locked position. It is therefore not possible to open the casement.

In an embodiment, the bolt, in its locked position, projects through the groove in at least one opening of the closing part and releases the groove in its unlocked position. Since the locking part is usually made of a metal, it stabilizes the bolt in its position in the event of transverse forces occurring by forcibly displacing the push rod fitting, for example due to a twisting of the handle olive without prior displacement of the bolt into its unlocked position to release the locking bolt. The bolt protrudes through the opening of the casement, for example and at least one opening in a wall of the closing part delimiting the groove into the groove in order to block the locking bolt. The bolt preferably projects through the groove of the closing part and dips into an opening in the further wall of the closing part delimiting the groove.

In order to block the locking bolt further, alternatively or additionally, the bolt, in its locked position, preferably projects through a transverse bore in the locking bolt or arrests the locking bolt with a fork-shaped opening. This locking bolt can be locked both within the locking part and at any point on the push rod fitting, for example also on a locking bolt to which no locking part is assigned. For this purpose, it is either necessary to modify the locking bolt through the transverse bore or to design the bolt in such a way that it also fixes the locking bolt outside of one of its end positions specified by the push rod fitting.

In a further alternative embodiment, the bolt can be moved outside the locking part in order to release the opening of the groove in its unlocked position or to lock the groove in its locked position. In its locked position, the bolt can, for example, lie directly against the locking part on the circumference or be slightly spaced from the locking part and in any case ensure that the locking bolt cannot leave the groove of the locking part.

If, for reasons of space, it is not possible to lock the locking bolt directly by means of the bolt, the bolt assigned to the frame cooperates with a locking element to block the locking bolt so that its linear movement from the locked position into the unlocked position results in a rotational movement of the locking element is implemented in such a way that a locking lug of the locking element blocks the locking bolt in the locked position and releases it in the unlocked position.

For example, the bolt can have a toothing in the manner of a toothed rack and, in the case of a longitudinal movement in the direction of the locked position, in which the bolt largely immerses in the casement or the frame, the pivoting or displaceably mounted locking element, which also has toothing, for example Move the locking bolt into the groove of the locking part.

The bolt is expediently held captively in the casement. Accordingly, the bolt can be moved in a straight line from its locked position, which is largely pushed into the sash frame, to its unlocked position, which projects largely beyond the sash frame, but cannot be completely removed from the sash frame.

A handle and / or a lock is assigned to the bolt for better handling. The handle can be, for example, a handle element or the key of the lock. With the optional lock, the bolt is secured in its locked position.

In order that the displacement of the bolt from its unlocked position pulled out of the sash frame into the locked position pushed into the sash frame takes place reliably, the bolt is held in the locked position by means of a spring element and can be brought into its unlocked position against the action of the spring element . Of course, the user must ensure that the bolt only takes up the locked position when the locking bolt is in the groove of the closing part is displaced, so that the sash frame can be tilted to a maximum in relation to the frame.

In order to avoid an excessively large torque acting on the handle olive via the associated handle piece, which can lead to damage to the entire push rod fitting, a handle piece is connected by means of a polygonal pin to a gear of the handle olive for actuating the push rod fitting, the polygonal pin weakening a cross-section in has its course between the handle and the gear. The cross-sectional weakening, for example a notch, represents a predetermined breaking point and enables the polygonal pin to be sheared off when the force exerted on the handle and the connecting rod fitting connected with it is inadmissible.

The bolt integrated in the sash frame prevents the push rod fitting from moving in its locked position. The push rod fitting and the window or door are operated using a known handle. No fitting-locking function is assigned to the handle itself, which is why any handle can be mounted and the operating function is separate from the locking function. Due to the weakening of the cross-section of the polygonal pin connecting the handle with a gear of the handle olive, a mechanical overload can cause e.g. B. by attacking the handle, overuse of the lock can be avoided.

It goes without saying that the features mentioned above and still to be explained below can be used not only in the respectively specified combination but also in other combinations. The scope of the invention is defined only by the claims.

The invention is explained in more detail below using an exemplary embodiment with reference to the associated drawing.

The arrangement designed as a window 1 essentially comprises a window frame 3 composed of a plurality of window frame profiles 2, and a wing frame 4 articulated on the window frame 3, which is joined from a plurality of window frame profiles 5. In the sash 5 is a circumferential groove 6 for arranging a Push rod fitting 7, wherein the push rod fitting 7 cooperates with a handle 8 of a handle olive 9 or a gear of the handle olive 9 in order to move the locking rod 10, which in the present case has a mushroom head 11, firmly connected to the push rod fitting 7, in one position first position in which the sash 4 is locked with respect to the frame 3, and at least in a second position in which the sash 4 can be opened. With a corresponding configuration of the installed fitting parts, it is often also possible to set a third position in which the sash frame 4 can be tilted relative to the frame 3.

Fig. 1 See contingent positions 12 for the arrangement of a bolt 13, the functionality of which is described below. It should be noted here that when the bolt 13 is arranged in the region of the longitudinal sash frame profile 5 provided with the handle olive 9, the bolt 13 can only effectively assume its locked position 18 when the sash frame 4 is locked with respect to the frame 3. When the bolt 13 is arranged in the area of the sash frame profile 5 on the underside, the bolt 13 can also effectively assume its locked position 18 when the sash frame 4 is tilted relative to the frame 3, as follows in an obvious manner.

To Fig. 1 the handle olive 9 is in a 6 o'clock position, in which the casement 4 is locked with respect to the frame 3. In this position, the locking bolts 10 are positioned in such a way that they engage in grooves 14 of associated locking parts 15, which are attached to the frame 3, which are open at one end and in different positions distributed over the circumference.

By rotating the handle olive 9 counterclockwise by 90 ° into a 3 o'clock position, the locking bolts 10 distributed over the circumference are moved out of the grooves 14 of the associated locking parts 15 and the sash 4 is due to the longitudinal side opposite the handle olive 9 existing suspensions for opening the window 1 relative to the frame 3 pivotable.

After a further rotation of the handle olive 9 by 90 ° counterclockwise to a 12 o'clock position, there are locking bolts 10 on the underside broad side of the window 1 in engagement with associated grooves 6 of correspondingly fastened locking parts.

In order to prevent the handle 8 of the handle olive 9 from rotating, in particular in the event of a violent penetration from the outside, into a 3 o'clock position in which the sash 4 can be opened, at least one bolt 13 which is displaceably mounted in the sash 4 the locking bolt 10 assigned to the bolt 13 is locked by moving the bolt 13 into its locked position 18. In the locked position 18, the bolt 13 blocks the displacement of the associated locking bolt 10 and in its unlocked position 19, the bolt 13 releases this displacement, after which the handle olive 9 can be actuated in the usual manner.

In order to prevent damage to the entire push rod fitting 7 in the locked position 18 of the bolt 13 when the handle olive 9 is subjected to a large force, a polygonal pin 23 of the handle piece 8 has a cross-sectional weakening 24 which serves as a predetermined breaking point. The cross-sectional weakening 24 is of course located in an area between the actual handle 8 and a gear which converts the rotary movement of the handle 9 into a straight-line movement of the push rod fitting 7.

After the 3 and 4 the bolt 13 lies in its locked position 18 in front of the locking part 15 in such a way that the groove 14 blocks and thus effectively prevents the locking bolt 10 from moving out of the locking part 15. The bolt 13 is provided with a lock 17 for securing against unauthorized actuation and for simplified handling with a handle 16 projecting beyond the casement 4. Furthermore, the bolt 13 is held captively on the sash frame via the lock 17 or the handle 16.

According to the 5 and 6 the bolt 13 is in its unlocked position 19, in which it releases the groove 14 of the locking part 15 so that the locking bolt 10 moves the handle olive 8 out of the groove 14 by means of a corresponding rotary movement of the grip piece 8 and opens the window 1 or the casement 4 can be tilted. In order to get from the locked position 18 into the unlocked position 19, the lock 17 assigned to the bolt 13 is opened and either retracted manually or moved back in a spring-operated manner, so that the free end of the lock 17 and thus also the handle 16 continues via the The sash protrudes as in the locked position 18, in particular when it is locked. Of course, the lock 17 is not absolutely necessary. For manual unsecured actuation, the bolt 13 can also be assigned only the handle 16, on which a user can grip with his fingers, or a spring-loaded push button which, in its depressed position in which the bolt assumes its locked position 18, releasably latches and, when actuated in the depressed position due to the action of the built-in spring, assumes an extended position to which the unlocked position 19 of the bolt 13 is assigned.

In an alternative embodiment corresponding to the 7 and 8 interacts with the frame 13 associated bolt 13 for blocking the locking bolt 10 with a locking element 20 which is coupled via a toothing 21 to the bolt 13 such that its linear movement from the locked position 18 in the unlocked position 19 in a rotational movement of the locking element 20 is implemented in such a way that a locking lug 22 of the locking element 20 blocks the locking bolt 10 in the locked position 18 and releases it in the unlocked position 19. The other processes, motion sequences and components are already shown as examples above.

In the present case, the sash 4 is pivotally mounted on the frame 3. However, it is obvious to the person skilled in the art that the sash 3 can also be mounted in a displaceable manner.
