Description

The present invention relates to a device, in particular a fitting arrangement for windows, doors or the like, with a faceplate, which is designed for attachment to a frame or casement of the window, door or the like, along a longitudinal extension of the faceplate between a release position and a locking position displaceable locking bar and at least one locking element arranged on the locking bar.

Such fitting arrangements are used, for example, as so-called edge closures in rebate grooves in window or door sashes. To switch the fitting, e.g. for locking or unlocking the sash frame with respect to the frame, the locking bar is displaced by means of an actuating element such as a handle or lever and a gear coupled to it, so that the locking element is engaged or disengaged from a locking part bring. Usually, a plurality of pin-like locking elements are attached to an arrangement of driving or locking bars coupled to one another. The faceplate is usually designed as a flat bar and provided with elongated holes through which the pin-like locking elements protrude and within which they can be moved. This structure is relatively complex. In particular, due to the large number of different components, both the manufacturing and the assembly effort are comparatively high.

The EP 0152 791 A2 discloses a fitting for sliding windows or sliding doors, which comprises a U-shaped cuff profile and a drive rod designed as a flat iron, the front of the cuff profile having slot-like openings for the passage of locking members.

In the field of hardware technology, we are looking for ways to simplify the manufacture and assembly of devices of the type mentioned at the beginning.

The object is achieved by a device, in particular a fitting arrangement, with the features of claim 1.

In a device according to the invention it is provided that the faceplate comprises a receiving section with an interior in which the locking bar including the locking element is arranged, and that the faceplate has at least one insertion opening opening into the interior. It is further provided in a device according to the invention that the locking element arranged in the interior releases the insertion opening when the locking bar is in the release position and that the locking element arranged in the interior at least partially blocks the insertion opening when the locking bar is in the closed position .

The faceplate is not designed as a flat bar as usual, but as a hollow body. This opens up the possibility of storing the locking bar in the faceplate regardless of the design of the fitting groove. The locking bar can also be particularly simple, so that a fitting arrangement according to the invention is inexpensive to manufacture. In addition, it is both optically and structurally advantageous if no locking pins protrude through the faceplate. Due to the fact that the locking takes place within the faceplate, the faceplate of the frame or sash frame in question can be made particularly appealing.

According to the invention, the receiving section comprises a hood which at least partially surrounds the interior and, in the assembled state of the fitting arrangement, projects into a rebate air formed between a frame and a sash of the window, the door or the like. By protruding into the rebate air in this way, it is possible for a closing part arranged on the faceplate of the frame to pivot as it were into the insertion opening when the rotatable casement is closed. The hood has a curved outer surface. In particular, it can be essentially semi-cylindrical. Specifically, the interior can extend between the hood and a rear wall of the faceplate, which in the assembled state of the fitting arrangement points to a fitting groove. Such a faceplate is comparatively easy to manufacture.

The invention also relates to a device, in particular a window, a door or the like, with a frame or sash, a locking bar which can be displaced along a faceplate of the frame or sash between a release position and a closed position, and at least one locking element arranged on the locking bar, wherein it is provided that the frame or sash frame comprises a receiving section with an interior in which the locking bar including the locking element is arranged, and that at least one insertion opening opening into the interior is provided on the faceplate of the frame or sash, which is in the interior Arranged locking element releases the insertion opening when the locking bar is in the release position, and wherein the locking element arranged in the interior at least partially blocks the insertion opening when the locking bar is in the closed position.

It goes without saying that a receiving section integrated into the frame or sash frame as well as a receiving section integrated into the faceplate is advantageous in that the locking bar can be designed particularly simple and the faceplate of the frame or sash frame in question can be designed particularly appealing.

According to the invention, the receiving section comprises a hood which at least partially surrounds the interior, which has a curved outer surface and, in the assembled state of the fitting arrangement, projects into a rebate air formed between a frame and a sash of the window, the door or the like.

The locking element is preferably received completely in the interior of the receiving section, that is to say no parts of the locking element protrude from the interior. In contrast to common fitting arrangements, in which the locking elements protrude visibly from the faceplate, the invention therefore preferably provides that the locking element or elements are countersunk in the faceplate or in the faceplate. This makes cleaning the cuff easier and gives it a particularly appealing appearance.

It is further preferred that the interior extends at least substantially over the entire length of the faceplate of a fitting arrangement according to the invention or of the faceplate of a window according to the invention or the like. This makes it easier to accommodate an elongated drive or locking bar.

One embodiment of the invention provides that the receiving section has a flat or curved insertion side, which in the assembled state of the fitting arrangement points against the closing direction of a movable casement of the window, the door or the like, and that the at least one insertion opening is formed at least in the insertion side . Thus an am Closure part fastened to the frame or a portion of the same when closing the window get into the interior of the faceplate, where it is available for engagement with the locking element. In principle, it is sufficient if the at least one insertion opening is formed exclusively on the insertion side. In order to facilitate the insertion process and, in particular in the case of a pivotable wing, to take account of the curved movement of the cuffs, it may be expedient that the insertion opening extends both over the insertion side and over at least one further side of the cuff rail, which does not run counter to the closing direction shows. In particular, the faceplate can be designed as a closed hollow profile and comprise a rear surface designed for fastening to the frame or sash, a front surface facing away from the sash of the frame or sash, and two side surfaces connecting the front surface and the rear surface. One of the side surfaces then forms the insertion side if it is a rotatable casement. If there is a sliding sash, the insertion side is formed by the front surface. It should be noted that the hollow profile can also have an at least partially rounded cross section, in which case, for. B. merge the side surfaces without an edge into the front surface.

The receiving section can have wall sections and / or guide sections delimiting the interior space, through which the locking bar is slidably guided. It is then not necessary to provide separate guides for the locking bar, so that the manufacture can be simplified. It is particularly advantageous that the faceplate can perform a double function in this embodiment, in that it serves on the one hand to cover the fitting groove and on the other hand to slidably mount the locking bar.

Apart from the at least one insertion opening, the interior is preferably completely closed. This makes cleaning easier and also prevents dirt from entering the interior.

According to a special embodiment of the invention, the hood is interrupted when viewed in a longitudinal extent of the receiving section, the interruption forming the at least one insertion opening. The interruption can, in relation to the longitudinal extent of the faceplate, largely run completely from one longitudinal edge of the rear wall to the opposite longitudinal edge of the rear wall. This enables a simple construction and ensures easy insertion of the associated locking part - even if the sash frame swivels.

A further embodiment of the invention provides that the locking element comprises an elongated bolt, the bolt axis of which runs parallel to a rod axis of the bolt rod. Such a bolt can move into an associated bolt receptacle without exiting the interior.

The locking bar can be designed as a straight flat bar, in particular as a straight flat iron. This enables particularly cost-effective production.

Alternatively or additionally, the locking element can be designed as an angled flat bar, in particular as an angled flat iron, with a first leg and a second leg, the first leg connected to the locking bar extending transversely or obliquely to a bar axis of the locking bar and the free end of the angled bar Flat leg comprising second leg runs parallel to the rod axis of the locking bar. This can further simplify production.

According to a special embodiment, the locking element, which is designed as an angled flat bar, is a punched-out or shaped form of the locking bar, which is designed as a straight flat bar. This means that the locking bar and the locking element have emerged from one and the same starting component, with only simple stamping and folding processes being required.

A plurality of locking elements are preferably provided on the locking bar and a plurality of insertion openings assigned to the locking elements are provided on the receiving section in order to ensure secure locking. The insertion openings can be arranged distributed along the longitudinal extent of the faceplate.

It is preferred that the locking bar extends without interruption over at least 50% and preferably over at least 75% of the total length of the faceplate of a fitting arrangement according to the invention or of the faceplate of a window according to the invention or the like. In contrast to common drive rod assemblies, which are composed of telescopically displaceable individual drive rods, a continuous locking rod is much easier and cheaper to manufacture.

A fitting arrangement according to the invention can comprise a closing part which has a functional section which is designed for insertion into the interior through the insertion opening, the functional section having a latch receptacle for the locking element. The bolt receptacle can be formed by any recess, passage, shoulder or the like adapted to the locking element in question. It is important that the functional section is adapted to the insertion opening and the depth of the interior of the receiving section with regard to its outer dimensions.

The lock receptacle can be designed for insertion of the locking element in a locking direction running parallel to a longitudinal extent of the receiving section, so that the locking element does not have to emerge from the interior in order to enter the lock receptacle. In principle, reaching behind of any portion of the closing part by the locking element with respect to the opening direction is sufficient to provide the locking function. However, it is preferred that the bolt receptacle is designed as a bushing. The cross section of the bushing can be adapted to the cross section of the locking element.

The closing part can comprise at least two and preferably exactly two bolt receptacles, which are spaced apart from one another with respect to an insertion direction defined by the insertion opening. This enables the casement to be optionally fixed to the frame in a closed position and in an energy-saving position.

The invention also relates to a window, a door or the like, with a window frame, a sash frame which is movable relative to the window frame and a fitting arrangement as described above.

Further developments of the invention are also specified in the dependent claims, the description and the accompanying drawings.

is a simplified perspective view of a locking part of a fitting arrangement according to the invention.

The in Fig. 1 and 2nd shown sash frame 11 of a window, a door or the like is composed of spars 13A, 13B, 13C, in which respective forend-side fitting grooves 15 are formed. By means of a fitting arrangement 19, the casement 11 is rotatably and possibly tiltably mounted on a frame, not shown. On the fitting groove 15 of the faceplate 14 of the upper spar 13B facing away from the rotating belt, a faceplate 21 is fastened, which has a longitudinal extension L running parallel to the fitting groove 15 and a hood 25 and an in Fig. 3 recognizable rear wall 27 includes. The rear wall 27 is preferably provided with protrusions which cannot be recognized and which engage behind inwardly projecting wall sections of the fitting groove 15 in order to hold the faceplate 21 on the sash frame 11 without the use of fastening means such as screws.

Between the hood 25 and the rear wall 27 there is an interior space 29 ( Fig. 3 ) formed, which extends largely over the entire length of the faceplate 21st extends. Caps 33 are arranged on the two longitudinal ends 30 of the hood 25. Thus, the interior 29 is completely closed - apart from four insertion openings 35, which are formed by interruptions in the hood 25 and are arranged distributed along the longitudinal extent L. How out Fig. 1 and 2nd emerges, the hood 25 projects in the assembled state of the fitting arrangement 19 into the rebate air formed between the sash 11 and the frame.

According to Fig. 3 and 4th there is a locking bar 37 in the interior 29 which carries respective locking elements 38 in the region of the insertion openings 35. The hood 25 and the rear wall 27 thus form a receiving section 28 for the locking bar 37. The locking bar 37 is designed here as a straight, continuous flat iron, the locking elements 38 being formed by punching out the flat iron in the form of angled tongues 39. Specifically, each tongue 39 has a first leg 40 and a second leg 41, the first leg 40 connected to the locking bar 37 extending obliquely to the bar axis A of the locking bar 37 and the second leg 41 comprising the free end 42 of the tongue 39 parallel to that Rod axis A runs. The second leg 41 thus defines an elongated bolt, the bolt axis R of which runs parallel to the rod axis A of the bolt rod 37 and the longitudinal extension L of the faceplate 21.

The locking bar 37 is completely received in the interior 29 together with the locking elements 38. The locking rod 37 is slidably guided along the longitudinal extension L of the faceplate 21 by wall sections of the hood 25 and the rear wall 27 pointing into the interior 29. By actuating an actuating element in the form of a handle 45 ( Fig. 1 and 2nd ) of the fitting arrangement 19, the locking bar 37 can be used using a not known, basically known fitting gear between the in Fig. 3 release position shown and in Fig. 4 shown closed position can be moved.

Out Fig. 3 and 4th it can be seen that the second legs 41 of the tongues 39 open the insertion openings 35 when the locking bar 37 is in the release position and block the insertion openings 35 when the locking bar 37 is in the closed position.

The locking elements 38 cooperate with locking parts 50, one of which is in Fig. 5 is shown. Each locking part 50 comprises a fastening section 51, by means of which the locking part 50 can be attached to the frame of a window, a door or the like. The fastening section 51 of the in FIG Fig. 5 Locking part 50 shown provided with a simple through hole 52 for a screw or rivet. A functional section 53 extends from the fastening section 51, which here is cuboid and has two bolt receptacles 55A, 55B spaced apart from one another. The bolt receptacles 55A, 55B are adapted to the flat bar-shaped cross section of the tongues 39. The functional section 53 is designed for insertion into the interior 29 in an insertion direction E through one of the insertion openings 35.

When a user closes the casement 11 with the locking bar 37 in the release position, the closing parts 50 fastened to the frame with the functional sections 53 pivot through the insertion openings 35 into the interior 29 of the faceplate 21. Subsequent actuation of the handle 45 from the in Fig. 1 Open position shown in the in Fig. 3 shown locking position, the locking bar 37 as in Fig. 3 indicated by an arrow in the closed position according to Fig. 4 postponed. Here, the second legs 41 of the tongues 39 move into one of the two bolt receptacles 55A, 55B, depending on how far the locking parts 50 protrude into the interior 29. If the When tongues 39 move into the front catch receptacles 55A with respect to the insertion direction E, the sash frame 11 is secured in the economy ventilation position on the frame. If, on the other hand, the tongues 39 move into the bolt receptacles 55B which are at the rear with respect to the insertion direction E, the sash frame 11 is secured to the frame in the completely closed state.

Overall, the faceplate 21 designed as a hollow body, together with the locking bar 37 on the inside, forms, together with the locking parts 50, an edge closure which is inexpensive to produce and easy to clean. In principle, the closing parts 50 could also be attached to the casement 11 and the faceplate 21 to the frame.

An embodiment of the invention, not shown, provides for the receiving section not to be part of a faceplate, but rather to be integrated in the casement frame or in the frame, that is to say it is formed in one piece with it. For example, a spar of the casement frame manufactured as a profile element could be provided with an elongated cavity, which forms a corresponding interior space and the boundary walls of which, in their entirety, can be regarded as a receiving section. Such a receiving section, including a locking bar received therein, could otherwise be configured as above with reference to FIG Fig. 1-4 described and a corresponding sash could in principle look just like in the Fig. 1-4 shown.
