Description

The present invention relates to a fitting assembly for a window, a door or the like, comprising a support portion adapted for direct or indirect attachment to a window sash or sash, door or the like, and a latch member pivotable about a pivot axis is stored at the storage section.

Such hardware assemblies are commonly referred to as "closures" and are used to selectively lock a movable wing of a window, door or the like to another movable wing of the window, door or the like, or to a stationary member such as a frame or floor sill or release. The storage section can in particular be attached to a faceplate or be formed directly on this, which in turn is provided for attachment to a corresponding frame member. So it is not absolutely necessary to attach the storage section itself on the glare or sash. For locking the wing, the locking element is pivoted such that it comes into engagement with a closing part which is arranged on or in another fitting part, a frame element, a threshold or the like.

Locking parts which protrude from a fitting part surface or from the floor are generally perceived as disturbing. This is especially true for such closures, which are intended for horizontal mounting on the wing underside. In such fitting arrangements, the locking members protruding from the floor or from the threshold are also barrier-free opposite. Another problem is that common fittings with pivoting locking element define only a single locking position and therefore z. B. hardly suitable for turn-tilt closures.

The DE 38 22 343 A1 discloses a locking device for a window closure, which has two swing-out lever with associated hook-shaped locking lugs. By turning the window handle both levers can be swung out at the same time. The one lever has a second engagement element, wherein in a first pivot position of the locking element designed as a lever, the hook-shaped locking lug is in a pivoted-out locking position, and wherein the second engagement element is in a pivoted-out locking position in a second pivot position of the locking element. In a third pivot position of the locking element are both the Verrieglungsnase, and the engagement element in a pivoted-release position.

It is an object of the invention to provide a fitting arrangement of the type mentioned, which is more flexible and allows a barrier-free construction.

The object is achieved by a fitting arrangement with the features of claim 1.

According to the invention, it is provided that the locking element comprises a first and a second hook element for engaging behind a closing part and that the locking element is a double hook with two free hook tips, wherein in a first pivot position of the locking element, the first hook element is in a pivoted-out locking position, wherein in a second pivot position of the locking element, the second hook element is in a pivoted-out locking position, and wherein in a third pivot position of the locking element both hook elements are in a pivoted-release position.

The term "swinging out" is to be understood in the sense that the relevant hook element is moved in the direction of the associated closing part in the outer space of the fitting assembly. Analogously, the term "pivoting" is to be understood that the relevant hook element of the associated Closing part is moved away in a retracted position. Due to the two hook elements, there is a release arrangement according to the invention both a release position and two mutually independent locking positions. Thus, z. B. a fixed point for a rotational position of the relevant wing and additionally a further fixed point for a tilted position of the wing can be realized. In principle, the locking element could also comprise more than two hook elements. The hook elements can be easily pivoted into respective hook receptacles and engage there behind suitable closing parts, so that no protruding closing parts are required. The hook intervention, inter alia, a particularly reliable lifting of a window or door leaf is possible.

It is preferred that the first pivot position and the second pivot position define respective end positions of the pivotal range of the latch member and the third pivot position is between the first pivot position and the second pivot position. Thus, the locking element can be pivoted in one go from one of the locking positions on the release position to the other locking position. In a closure designed in this way, it is possible, in particular, to switch over from a closed position via a release position into a tilted position, the respective wing being secured against being lifted due to the hook engagement both in the closed position and in the tilted position.

A fitting arrangement according to the invention can be designed in particular as a turn-tilt closure, wherein the first pivot position of the locking element of a closed position of the turn-tilt closure, the second pivot position of the locking element of a tilted position of the tilt and turn closure and the third pivot position of the locking element of an open position corresponds to the turn-tilt closure. Such a shaped closure can be operated in the usual way.

Preferably, the hook elements are curved in opposite directions, so that a symmetrical configuration of the locking element is possible. The free ends of the hook elements, so the hook tips can point away from each other.

Preferably, however, it is provided that the free ends of the hook elements face each other, so in a sense opposite. As a result, namely, the pivoting of the locking element from one to the other engagement position can be kept relatively short, for example at less than 90 °.

The storage section can be arranged on a face-plate rail which has at least one opening through which the hook elements can be swung out. Depending on the application, a common opening may be provided for both hook elements, or respective openings may be provided for each of the hook elements. In the simplest case, the opening can be a rectangular recess in the face-plate rail. The storage section can be attached directly or indirectly to the faceplate or be made in one piece with this.

It is preferred that, in the third pivoting position of the locking element, no portion thereof projects through the at least one opening of the face-plate rail. This can be achieved, for example, by the fact that, upon a pivoting movement of the locking element from the first to the second pivot position, the passage of the second hook element through the associated opening only begins after the first hook element has been moved back at least to the front of the face plate, or vice versa. During assembly of the closure at the lower edge of the wing, the underside of the fitting can thus run in the immediate vicinity of the floor, which, in conjunction with a bottom hook receptacle, enables barrier-free design.

It is preferred that the pivot axis extends at right angles to a longitudinal axis of the faceplate rail. That is, it is a stulpseitiges pivoting in and out of the locking element is preferred.

A fitting arrangement according to the invention can have a control slide mounted linearly displaceably on the mounting section and a conversion device, wherein the conversion device is designed to convert a displacement movement of the control slide into a pivoting movement of the locking element. Such a fitting arrangement is particularly well integrated into existing drive rod systems. In particular, the control slide can be coupled to a drive rod, for example via suitable positive locking elements. Furthermore, the spool may be plate-shaped to allow a particularly simple production.

According to one embodiment of the invention, the conversion device comprises a link control with a guide slot and a sliding block received in this, wherein the guide slot is formed on the locking element and the sliding block is arranged on the spool, or vice versa. This allows a particularly simple and reliable construction.

Preferably, the sliding block is spaced from the pivot axis. A movement of the spool is thus always converted into an acting on the locking element torque.

The locking element can be designed as a one-piece, preferably plate-shaped, component in order to keep the manufacturing costs low.

According to a particular embodiment of the invention, the storage portion is designed for insertion into a fitting groove of the window, the door or the like.

It can be provided that the storage section is formed like a housing and the locking element is housed in the housing-like storage section. A box-like design of the storage section facilitates its insertion into a fitting groove and also protects the movable components.

Further developments of the invention are set forth in the dependent claims, the description and the accompanying drawings.

In the Fig. 1-4 partially shown fitting assembly 11 includes a faceplate 13 and attached to the faceplate 13 storage portion in the form of a closure box 15. The closure box 15 is designed specifically for insertion into a recess in a fold of a wing of a window, a door or the like. In the Fig. 2 to 4 the front housing half 16 of the lock box 15 is omitted in order to illustrate the position of the components located in the lock box 15.

As in particular from Fig. 4 shows, a locking element 17 is housed in the closure box 15 and mounted by means of a pivot pin 19 about its longitudinal axis 20 pivotally mounted on the closure box 15. The longitudinal axis 20 of the pivot pin 19 in this case extends at right angles to the longitudinal axis 21 of the faceplate 13th

The locking element 17 is executed in the illustrated embodiment of the invention as a plate-shaped component. As shown, it has two hook elements 25a, 25b, which are curved in opposite directions and arranged so that their free ends 27 face each other. In the in Fig. 4 shown pivot position of the locking element 17 are both hook elements 25a, 25b within the lock box 15, wherein no portion of the locking member 17 protrudes beyond the front side 29 of the faceplate 13. Therefore, the hook elements 25a, 25b are both in a release position here.

By pivoting the locking element 17, starting from the in Fig. 4 However, shown position, each of the hook elements 25a, 25b are pivoted out through a corresponding opening 33 of the faceplate 13 from the closure box 15, as for the left hook member 25a in FIG Fig. 1-3 is shown. In this position of the locking element 17, the hook element 25a an associated closing part (not shown) engage behind, which is arranged on another fitting part, a blend or sash profile or a threshold. That is, the hook element 25a pivoted out of the closure box 15 is in a locking position. It is understood that the right in the image hook element 25b is pivotally in such a locking position and that due to the arrangement of the two hook elements 25a, 25b only one of them can be in the pivoted-out locking position.

The switching of the locking element 17 between the three different functional positions by means of an arrangement of drive rods 35, which are guided in a basically known manner on the face plate 13 slidably and with an operable fitting gear (not shown) coupled. To implement the linear displacement movement of the drive rods 35 in a pivoting movement of the locking element 17, a transfer device 36 is provided with a slide control 37. As in particular from Fig. 3 and 4 shows, in the locking element 17, a guide slot in the form of a slot 39 is formed, in which a sliding block 40 is added. The sliding block 40 is connected at one of the longitudinal axis 20 of the pivot pin 19 spaced location with a control slide 43 which is mounted along the longitudinal axis 21 of the faceplate 13 slidably in the closure box 15 and coupled to the drive rods 35. In the illustrated embodiment, the spool 43 comprises two parallel control plates 45, between which the locking element 17 is arranged. The coupling of the control plates 45 with the drive rods 35 via formed on the end faces of the control plates 45 engagement lugs 47 which engage positively in matching recesses 49 of the drive rods 35.

When the locking element 17 via the link control 37, starting from the in Fig. 1-3 shown position is pivoted clockwise, the left hook element 25a is first pivoted into the closure box 15 in the image. Subsequently, the right in the image hook element 25b is pivoted out of the closure box 15 and thus moved into a locking position. However, before the right hook element 25b passes through the corresponding opening 33 of the faceplate 13, the left hook element 25a is already completely behind the front side 29 of the faceplate 13 or at least flush therewith, so that the release position of both hook elements 25a, 25b according to FIG Fig. 4 as an intermediate position between the two locking end positions results. When swinging back the locking element 17, the processes proceed analogously in the opposite direction.

The fitting arrangement 11 described above can thus be carried out as a turn-tilt closure, wherein the in Fig. 1-3 shown pivot position of the locking element 17 a closed position of the turn-tilt closure, the in Fig. 4 shown pivot position of the locking element 17 an open position of the turn-tilt closure and that pivot position of the locking element 17, not shown, in which the right hook member 25b is pivoted out of the closure box 15, corresponds to a tilted position of the turn-tilt closure. Both in the closed position and in the tilted position of the corresponding window or door is reliably secured against digging.

It is understood that instead of the box-like closure box 15, an arbitrarily shaped storage portion, for example in the form of a simple plate, can be provided. Instead of a "swinging out" of the locking element 17 from the closure box 15 and a "pivoting" of the locking element 17 in the closure box 15 would in this case a "swinging out" of the locking element 17 from the respect to the faceplate 13 backward Space or a "swinging" of the locking element 17 in this rear space done.

The fact that the locking engagement of the tilt and turn closure via pivotable hook elements 25a, 25b takes place, on the one hand can engage in recessed bolt receptacles and on the other hand in the open position of the turn-tilt-lock does not protrude beyond the front side 29 of the faceplate 13, can during assembly of the turn-tilt lock on the underside of the wing, the faceplate 13 are guided very close to the ground, so as to meet, for example, the requirements of a "barrier-free construction".
