Description

The invention relates to a fitting for a window, a door or the like. With a drive rod covered by a faceplate, with a locking element of a so-called rod exclusion attached to at least one of its ends. Such fittings are used, for example, in double-leaf windows without fixed vertical set timber, that is to say in windows which, despite the two leaves, only have a fixed frame consisting of two longitudinal beams and two transverse beams. It is usually the case with this type of window and door that one wing normally remains closed and only is opened for cleaning purposes. For this reason, it is often referred to as a cleaning wing. In contrast, there is the other wing, the so-called ventilation wing, which is used as with single-wing windows. For example, it can be a turn-tilt wing. Appropriately, the ventilation wing is locked in the closed position against the cleaning wing, because, as I said, there is no vertical fixed frame spar (no vertical set timber) between the vertical spars that are assigned to each other. Instead of or in addition, you can of course also lock the ventilation wing against the fixed frame.

In particular, if the ventilation wing is locked against the cleaning wing, a secure closed position of the cleaning wing is required. For this reason, as I said, it is locked in the manner of a bar exclusion parallel to the plane of the faceplate. The upper and the lower connecting rod ends emerge when locking up or down, the connecting rod ends either being designed as locking elements or bearing them. In its locking position, each locking element engages in a locking receptacle on the associated fixed frame cross member, which is expediently located on a striking plate or a comparable fitting part.

In the case of a wider cleaning wing in particular, locking is simply not via the so-called rod exclusion sufficient. This applies above all when the ventilation wing is locked against the cleaning wing. In such a case, additional locking at the top and / or bottom of the cleaning wing is important. However, such a lock requires the use of a corner deflection on the upper and / or the lower corner of the cleaning wing assigned to the ventilation wing. However, each corner deflection itself has a faceplate and this must connect as close as possible to the vertical faceplate, even connecting to the latter if possible. However, this requirement is precluded by the bar exclusion.

The object of the invention is therefore to develop a fitting of the type described in such a way that it allows the optional connection of one or at each corner a corner deflection for an additional locking on the upper and / or lower cross member of the cleaning wing without dispensing with the rod exclusion.

To achieve this object, it is proposed according to the invention that the fitting is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. This fitting is installed and used in the same way as the known one, but, as required, in addition to the bar exclusion, it also offers the possibility of using one or at each end of a corner drive for one or each additional locking device of the cleaning wing at the upper and / or lower wing end. There is practically no additional material involved and the additional processing costs are not worth mentioning, particularly with regard to the more universal use of this fitting. In the case of using one or two corner deflections, the coupling of the force deflection means of the corner deflection, i.e., for example, the guided spring straps to the drive rod on the opposite side of the hinge of the cleaning wing, is preferably carried out via a pin of the corner deflection which engages in a corresponding hole in the vertical drive rod. It is expressly pointed out that, as a rule, no corner deflection is required or used and, above all, the cleaning wing is locked against the fixed frame by means of a so-called rod exclusion. If the ventilation wing is a turn-tilt wing, the tilt bearing for the ventilation wing is usually also on the cleaning wing. For this reason alone, the cleaning wing must be securely locked in the closed position.

A further development of the invention provides that the outer surface of the faceplate runs approximately flush with the outer surface of the locking element. Both usually have a flat cross section.

Another embodiment of the invention is that the Drive rod is bent in the end area. This means that the locking element is made in one piece with the drive rod. In addition, one expediently reduces the width of the drive rod in the end region approximately from the offset, in particular from both sides, by the same amount, so that the opening can also be made symmetrically to the longitudinal central axis of the faceplate. Contrary to the illustration in FIG. 2, the drive rod is normally somewhat narrower than the faceplate, so that the cover rail can rest on both sides of the drive rod groove. If you nevertheless reduce their width in the end area, you get wider webs to the side of the opening.

Another embodiment of the invention is characterized by a rectangular shape of the opening, the width of which corresponds approximately to the width of the connecting rod end piece. As a result, the opening serves as a longitudinal guide and the opening is only wider than the locking element by the play required for this.

A preferred embodiment of the invention is characterized by two mutually facing projections, tongues or the like, which are assigned to the longitudinal sides of the opening and are essentially in the drive rod plane, the width of the drive rod in the region of the offset being approximately equal to the distance between the two tongues or is reduced. These projections or the like are used to guide the locking element, in particular when Unlock, and to secure the position in the transverse direction with the locking element withdrawn. The repeated reduction of the drive rod in the area of the crank, that is to say the intermediate piece between the parallel drive rod parts, can be punched out, for example, in one operation by creating the locking element. The two tongues or the like are expediently manufactured in one piece with the faceplate, in particular in the form of stampings. When punching the opening, these tongues can be formed and, after the punching process, they are only pushed out of the faceplate plane using a suitable embossing tool and transversely to their plane.

In a further development of the invention, the drive rod and the faceplate are parts of a gear, particularly a folding lever gear, which can be inserted into a rebate groove. Its control handle is advantageously only accessible when the ventilation wing is open or at least partially open, which is desirable in terms of safety but also the aesthetic appearance in this area.

A particularly preferred variant of the invention is characterized in that the free bent or angled end of the faceplate carries a coupling half for coupling to a coupling counter-half of a further, transverse drive rod, in particular a corner deflection of an additional locking device. In principle, such a clutch is already in itself knows, but with a different type of fitting or more precisely, with a fitting without bar exclusion. In accordance with this prior art, the coupling piece can have a T-shaped shape and can be coupled with a C-shaped coupling counterpart at the associated free end of the further faceplate of the corner deflection in a snap-in or snap-in manner. The corner deflection therefore only has a faceplate on its one leg, which is horizontal in the position of use, while its vertical leg is covered by the faceplate of the gear mechanism or folding lever mechanism.

A cleaning wing 2 and a ventilation wing 3 are mounted on a fixed frame 1 or frame. The cleaning wing 2 is a pure rotating wing and it can be rotated about a vertical axis assigned to the left vertical frame spar 4. In the exemplary embodiment, this is made possible by three rotary bearings 5, 6 and 7. This wing usually remains closed and is only opened for cleaning purposes. It is locked against the fixed frame 1 with the aid of the fitting according to the invention described below.

The second wing 3 is intended as a ventilation wing and, in the exemplary embodiment, it can both be rotated about an axis assigned to the right vertical frame spar and tilted about a lower horizontal axis. Locking and switching from one to the other mode of operation takes place in a known manner via a three-position gear 9. The handle of this gear 9 is also used to move locking bolts in the vertical direction, which with corresponding locking counterparts, in particular striking plates, on the right vertical spar 10 of the cleaning wing 2 work together. The right vertical wing spar 10 and the left vertical wing spar 11 of the ventilation wing 3 are directly assigned to one another, ie the fixed frame 1 has no additional vertical spar at this point, that is to say no so-called vertical set timber. The last-mentioned term in no way means that the fitting according to the invention can only be used with frames made of wood; frames, for example made of aluminum or plastic.

The locking of the cleaning wing 2 with respect to the fixed frame 1 takes place in the so-called rod exclusion. For this purpose, locking elements 15 and 16 are attached, in particular molded, to the upper and lower ends of a drive rod 13 which can be moved up and down on the spar 10 in the sense of the double arrow 12 and which is covered by a faceplate 14. Each engages in a striking plate or the like 17 or 18 on the lower or upper fixed frame cross member 19 or 20.

The driving days 13 and the faceplate 14 are parts of a gear that can be inserted into a rebate groove, in particular rebate lever gear 21, with an actuating handle 22 accessible. However, it can also be a gearbox with an attached operating handle.

In order to be able to easily adapt to different wing sizes or wing heights, the drive rod 13 is formed at least in two parts. The same naturally applies to the faceplate. The unit consisting of the drive rod part 13a and the faceplate part 14a can be cut to the size corresponding to the respective wing height. The connection of the drive rod part 13a and the drive rod part 13 via a U-shaped toothed slide 23 and the formation of the free end of the drive rod part 13a as a double rack 24. For the A connecting strap 25 is provided on the faceplate parts. The toothed slide 23 makes it necessary to bend the drive rod in this area. An element 26 is used to support the faceplate 14 at the base of the frame groove. A fastening screw can also be attached there and finally it can also be used to guide the drive rod 13.

The faceplate is bent at its end facing the upper and / or also the lower right wing corner of the cleaning wing 2 against the plane of the drive rod 13. In addition, there is an opening 27 at this point, the upper end of which extends into the curved piece 28 in FIG. 2. This results in an exit possibility for the locking element 16, which is made in one piece with the drive rod 13. The same applies, if applicable, to the lower right wing end.

The drive rod is bent at its free end and preferably reduced in width. The width of the opening 27, apart from the necessary play, corresponds to the width of the locking element 16. The longitudinal edges of the opening 27 support the locking rod in its main loading direction, that is to say perpendicular to the wing plane. The bend is made so that the outer surface of the locking element 16 is flush with that of the faceplate 14. The arc shape and the length of the opening 27 are selected so that the invisible inner surface of the locking element can be supported by the upper end edge of the opening 27. With the lock retracted in the direction of arrow 29 and thus locked out Gelungselement 16, the latter is supported on two tongues 30 under the locking element. In Fig. 2, only one of these tongues is shown. They point against each other and are formed on the two longitudinal webs 31, which laterally limit the opening 27. These are two punched-out tongues which have been pressed out against the plane of the drive rod 13.

The area of the drive rod 13 assigned to the tongues in the locked position is reduced in width or reduced again. This makes it possible to push the sloping connecting piece between the locking element 16 and the drive rod 13 between these two tongues 30. From the above it can be seen that both the opening 27 and the locking elements 15 and 16 are arranged symmetrically to the longitudinal central axis of the drive rod and face plate. Instead of this, it is also possible, although not necessarily recommended for reasons of stability, to provide an open-sided recess and an asymmetrical locking element instead of a closed opening.

The cleaning wing 2 can be securely locked against the fixed frame 1 with the fitting described above. However, if this frame is comparatively wide, as is shown by the exemplary embodiment according to FIG. 1, it is desirable and advantageous if the wing is additionally located at other points can be locked. The design of the fitting according to the invention enables a so-called corner deflection 33 to be coupled to the folding lever mechanism 21. The force deflecting means of this corner deflection, for example one or more spring bands, are connected to a coupling pin 34 which passes through an elongated hole 35 in the angle leg 36 and into a corresponding bore in the drive rod 13 can be inserted. As a result, the up and down movement in the direction of arrow 37 can be transmitted to the force deflection means 38 and forwarded to the horizontal leg. The horizontal movement is transmitted from the force deflection means to a horizontal drive rod 39 or 40, which carries a locking element 41 or 42. Expediently, this is a roller pin which interacts with a striking plate 43 or 44 or the like on the associated horizontal fixed frame spar. In the exemplary embodiment, an additional locking is achieved in the middle area at both the upper and lower ends of the cleaning wing 2.

The free end of the faceplate 14, that is to say essentially the part of the arch piece 28 which extends in the horizontal direction, forms a coupling half 45. It works together with a coupling counter-half 46 on the associated free end of the faceplate 47 of the corner deflection 33. The coupling half 45 has a substantially T-shaped shape and, when coupled, it engages in a slot of a corresponding shape. The coupling counter half 46 is suspended in the direction of arrow 29 in the coupling half 45.

From the above it is clear that this fitting can be used both with and without additional locking, i.e. can use with and without one or two corner drives 33. In any case, the "coupling" of corner steering systems has no influence on the mode of operation of the rod exclusion.

The bore group 48 on the faceplate 14 is used to fasten a striking plate or the like, which interacts with a locking pin on the closing side of the ventilation wing 3.
