A frame portion (5) is fixed to a frame (4) of the window or door. An inclined groove portion of the protrusion portion (5a) is cooperated with one recess portion for stopping and/or pitching the sliding portion or casement (3), and is cooperated with another recess portion for locking the fitting portion or casement in a closed position. An independent claim is included for method for operating espagnolette fitting structure on casement of window and door.

Description

The claimed invention relates to a drive rod fitting (claim 1) for a window or a door with a drive rod and a fastenable to the frame part of the window or the door projection. The espagnolette fitting forms a device for parking and / or hiring the wing of the window or the door. A method is also claimed (claim 11); in him wings and frame are part, not against the espagnolette fitting (claim 1).

Devices with a closing plate and moving locking pins are known from the following documents. In EP 1 582 673 B1 (Winkhaus ) EP 1 580 374 B1 (Winkhaus ) and EP 1 580 375 B1 (Winkhaus ) is a gate part fixedly mounted on the frame, so that a slot-shaped recess, which holds the wing with his moving from the drive rod drive pin in a parked position, the room interior or the wing flap is a piece wide open. In this case, the slot is preceded by a holding bridge to prevent complete opening of the wing.

This leads to window constructions with "small axial dimension" (window constructions with a narrow design) to the fact that the connection pin must be offset from the center plane of the drive rod laterally strong or the closing plate dominates the frame considerably.

The invention is based on the task to improve the espagnolette fitting in terms of increasing the stability and also to secure the closed position.

According to the invention the above object is achieved by claim 1 by a drive rod fitting for a window or a door with a drive rod and a link member which is arranged on the drive rod and has at least one (transversely directed) recess as inclined track. The drive rod fitting according to the invention further comprises a frame part, which is fastened to a window frame of the window or the door and has at least one projection. The projection is designed or positioned so that it cooperates with the inclined portion of the recess, so that through the at least one recess, a guide on or opposite the projection when parking and / or hiring a wing of the window or door can be done. A lock in a closed position and / or unlocking for an open position (pivoting) takes place in cooperation with another recess section.

The gate part with the at least one recess is slidably mounted on the wing and provides a guide or control against. the at least one projection which is attached to the frame part, so that a reliable and secure setting of a gap opening is possible. At the same time, the at least one recess and the at least one projection are designed and positioned such that a locking of the blade can take place during a corresponding movement of the drive rod. The at least one recess and the at least one projection are arranged to each other in the locking position so that a movement for hiring or stopping or for pivoting the wing is not possible.

A method operates according to claim 11.

The first recess portion preferably has a slanting piece for providing the guidance or control when parking or pitching the wing, so that with the inclination of the slope and the length of the first recess suitable parameters are given to a desired large gap depending on the overall structure of To be able to achieve wings and frame (claim 3).

On the other hand, the second recess portion may have a parallel to the frame extending guide (claim 4), so that the second projection immediately upon entry into the second recess portion reaches a locking of the wing, even if an end position of the hand lever for adjusting the closed position of the wing has not yet reached is. Thus, a reliable closed position and locking of the wing can be achieved even before a complete operation of the hand lever.

In an advantageous embodiment, the guide member has a first recess portion and a second recess portion and the frame member has a first projection which cooperates with the first recess, and a second projection which cooperates with the second recess (claim 2). There is a recess portion and an associated (first) projection to ensure precise guidance of the relative motion of the link and the first projection when the wing is turned on or off. For the locking, a second recess portion and a corresponding projection is used. This allows a special adaptation of the respective projection with associated recess portion for the corresponding function.

In an embodiment variant, a single fastening part is provided (claim 5), with which the slide member is attached to the drive rod, which does not result in large constructional overhead, for example, compared to the Espagnolette described above in the introduction.

In one embodiment, the single fastening part is arranged laterally between the first recess and the second recess (claim 6), so that overall a very compact (space-saving) structure is possible without limiting the size or length of the first and the second recess got to. Therefore, in particular, the first recess provided for turning on / off can be provided with a suitable geometrical shape and size to obtain the largest possible gap opening.

In an advantageous embodiment, two recessed sections are provided (claim 7): a first guide or track and a second guide or track connected thereto. The first guide, in cooperation with the (only) one projection, will control the position of the sash when parking or pitching, and the second guide will establish the lock in cooperation with the projection. Thus, in this embodiment, a single recess is configured such that the first and second tracks are contiguous so that the projection may transition continuously from the first track to the second track as, for example, the wing returns from the gap opening position and then locked or vice versa.

In one embodiment, the continuous recess is open on one side (claim 8), so that pivoting of the wing can take place without being influenced by the projection. By virtue of the (lateral) opening provided in the recess, pivotal movement of the blade can take place without interference from the projection, and yet a continuous transition from the guided movement for turning the blade on or off to the locking position can take place.

Advantageously, only one recess and only one projection are provided (claim 9), so that in particular with regard to the frame part (with the single projection) no additional design effort arises.

In a further advantageous embodiment, the espagnolette fitting further comprises a first fastening part and a second fastening part (claim 10), which together but at a distance connect the sliding part with the drive rod. This will be ensures even greater stability of the connection of the link member to the drive rod, so that a reliable operation is ensured with precisely defined positions of the link member with respect to the frame part over a long period of time.

The Figures 1 and 2 are cross-sectional views, with a sash 3 and a frame 4 are shown. It shows FIG. 1 the "closed position" and FIG. 2 the position "gap opening", as used for night ventilation. As usual in door or window fittings is in the sash 3 at the end face a groove 3a with therein slidable and by a hand lever (not shown) of the fitting operable drive rod 1, which is also referred to as a drive rail provided. A cover rail 10 extends parallel to the drive rail 1 and is defined in the groove 3a at its upper end (at the upper edge of the groove).

The drive rail 1 is connected via a fastening part 12 with a link piece 2. The fastening part 12 engages through a guide slot 11 in the cover rail 10.

A frame part 5 is stationary or rigidly attached to the end face of the frame 4 and acts together with the fixed or fixed to the drive rod 1 link piece 2. The frame part 5 has a downwardly projecting pin 5a on a frame plate 5 ', for example at its lower end has an enlarged diameter collar 5b, which contributes to the higher stability, as to the FIGS. 3 and 4 is explained.

It is advantageous if the pin 5a of the frame part is so formed or attached to the frame plate 5 'that it comes to lie with its edge region close to the abutment surface 4a of the frame 4, e.g. with a distance of less than 1 mm. The pin 5a is oriented close to the outer edge of the cover rail 10, in particular slightly beyond (outward).

The contact surface 4a is the surface on which the wing 3 in its closed position according to FIG. 1 is applied. From this contact surface measures the Abstellweite or gap opening X, which should be large despite narrow wing profile. Starting from this surface 4a, the axial dimension A is determined to the middle of the groove 3a. The dimension A is FIG. 1 located.

The gate part 2 (= the backdrop) of the device is stationary and thus rigidly attached to the drive rod 1 via the connecting part 12. The link part has a backdrop-shaped, at least to the pin 5a open towards recess 2a as a web, which in the FIGS. 3 and 4 is shown. It has a rearwardly closed 2a "'section 2a ₁ in the example shown, which runs parallel to the drive rod 1. A section 2a ₂ which is open towards the other side and extends obliquely to the drive rod 1, is delimited by flanks 2a' and 2a" at. The first section 2a ₁ can also open to the rear from the backdrop 2 expire.

The angle of the inclined portion 2a ₂ is in the range between 30 ° and 45 °, advantageously at an angle of 35 ° ± 10%.

The sliding part 2 is in advantageous applications, at least in the engagement region of the collar 5b, undercut, as shown in the Figures 1 and 2 is recognizable. This undercut is behind the acting as a track / guide recess 2a (in Figures 1/2 "under" the leadership 2a). It affects a height section 2c, which becomes wider than the track / guide 2a.

Due to the position of the pin 5a "very close" to the outer surface or contact surface 4a of the frame, it is possible to form the oblique portion 2a _{2 of} the recess 2a in a long length and thereby achieve a large measure X of the Flügelabstellung for the night ventilation. For this purpose, the rear rebate is used for receiving a wide link part 2.

The length of the inclined portion 2a ₂ is at least 10 mm. This also favors the use of the device described in wing / frame combinations with a small axial dimension A.

The embodiment described makes it possible to give the sliding part 2 on both sides of its recess 2a, in particular on the outer side, particularly strong or reinforced limbs for the flanks 2b 'and 2b " Pintle 5a enlarged in diameter collar 5b a relatively high degree of security against Aushebeln or tearing of the wing from its parked position (the night ventilation) can be achieved.

Other embodiments will now be described in more detail.

Related to the FIGS. 5 to 10 Further illustrative embodiments will now be described in more detail, with reference to the description of FIGS FIGS. 1 to 4 Reference is made.

In particular, it should be noted that the components already described there with the same reference numerals in the FIGS. 5 to 10 occurrences and their renewed description is omitted if necessary. Nevertheless, the properties of this in the context of FIGS. 1 to 4 also part of the disclosure, even if no separate list of such properties in the description of the FIGS. 5 to 10 he follows.

FIG. 5 shows a plan view of the end face of the sash 3, which rests against the contact surface 4a of the frame 4, as already in the context of FIGS. 1 to 4 is explained. Furthermore, this is in FIG. 7 Frame part 5 shown in more detail provided so that it has the projection 5a and a further projection 50a, both of which may be designed as also described above. The projections 5a, 50a may be designed as in the context of FIGS. 1 to 4 previously explained. The link part 2 is fixed via the slot 11 with the fastening part 12 on the drive rod 1 rigid (stationary).

The design and function of the components 3a and 10 are as previously described in connection with FIGS FIGS. 1 to 4 is described.

Further, the recess 2a in Figures 5 ff formed in such a way that it allows in cooperation with the projection 5 a controlled hiring and parking the wing 3, as for example, previously in the context of FIGS. 1 to 4 is described.

Furthermore, a second recess 20a may be provided in the gate part 2, which cooperates with the second projection 50a so that a locking of the wing 3 is achieved.

In the in FIG. 5 shown position of the blade 3, an unwanted opening of the blade 3 is reliably prevented by the located with the recess 20a in engagement second projection 50a, provided that the drive rod 1 is not actuated by a lever, not shown. This is referred to as a closed position of the wing or the espagnolette fitting 3.

FIG. 6 shows a "neutral" position of the guide member 2, in which neither the projection 50a with the recess 20a nor the projection 5a with the recess 2a are engaged. The wing 3 can be actuated, for example, to perform a pivoting movement without being influenced by the projections 5a, 50a.

FIG. 7 shows a position of the guide member 2, which is achieved for example by further actuation of the visible in the guide slot 11 drive rod 1, wherein increasingly the projection 5 a with the recess 2 a is engaged, which thus serves as a track or guide to control the generation of To allow gap opening X, as previously in the context of FIGS. 1 to 4 is explained. It results from a left shift of the gate 2 FIG. 6 in the location of FIG. 7 , Here the projection 5a has arrived at the end 2 * of the inclined track 2a.

FIG. 8 shows a side view of a portion of the frame 4 with the frame part 5, which has the two projections 5a, 50a, a locking ( FIG. 5 ) and a guided generation of a gap opening (off FIG. 6 to FIG. 7 ) in cooperation with the respective recess 20a and 2a, respectively. In the in FIG. 6 shown "neutral" position of the guide member pivoting without obstruction by the projections 5a, 50a take place, as previously explained. The scenery lies between the two projections 5a, 50a, without any of them engaging in the associated track 20a or 2a, that is to say being spaced therefrom.

As already stated above, can be achieved by providing the two separate recesses 2a and 20a in the guide member 2 with the fastening member 12 arranged therebetween a very compact structure, wherein the parallel extension of the right recess 20a, ie their extension parallel to the contact surface 4a (or drive rail 1), a reliable locking allows, even if the end position of the sliding part 2, by the length of the recess 20 a and a required actuating travel of the drive rod is given, not yet reached. Already "upon entry" of the projection 50a in the recess 20a is a locking of the wing, so that it occupies a reliable closed position even without reaching the possible end position 20a * in the gate part 2.

On the other hand, the left-hand recess 2a can be designed specifically for reaching the desired gap opening X, as is also the case in the context of FIG FIGS. 1 to 4 is explained.

FIG. 9 shows a further embodiment in which the cam member 2 has a single recess 200, which has a first guide or track 200a and a second guide or track 200b, which are continuous, ie merge into one another. Thus, the one protrusion 5a, which in this advantageous embodiment is provided as a single protrusion, can pass continuously from the web 200a, in which a desired gap is set, into the web 200b, which ensures a locked state of the blade, as before is explained.

Furthermore, the recess 200 has a (lateral) opening 200c, which corresponds to a "neutral" position of the sliding part 2 with respect to the projection 5a, so that in this position, the wing is movable outwardly without any obstruction or blocking by the Projection 5a takes place.

In the illustrated embodiment, at least two fastening parts 12 a and 12 b are further provided on the respective outer edge (left and right) of the link part 2 to connect the link part 2 with the visible in the guide gap 11 drive rod 1, so that increased stability for the Gate part 2 in particular with regard to a possible distortion of the position of the sliding part 2 results.

In this way, improved tracking accuracy is achieved for guiding the projection 5a both in the track 200b and in the inclined track 200a.

FIG. 10 shows schematically a side view in which the frame part 5 is shown with the single projection 5a on the plate 5 ', which is sufficient, however, to ensure a guided gap opening and an efficient locking, as well as an undisturbed pivoting movement of the wing due to the provided lateral Opening 200c in the gate part 2 is possible.
