Abstract

The component (3) is mounted on the fixed or leaf frame (1,2) of a door or window, and works via a contact face between the frames on relative movement between the latter against a mating component (5) on the other frame. One or the other of the components is on a plug portion (6) inserted in a connection area (8) of a universal holder (7) on one of the frames. The holder can have different connection areas to suit different components, and the plug portion and holder can be secured together by clips or screws. The component (3) can form a vertical guide with horizontal ramp face (4) between the frames for a mating boss (5), the plug portion being inserted vertically from the top. The connection areas are in pairs and symmetrical in the horizontal direction.

Description

The present invention relates to a functional element according to the preamble of claim 1.

Such functional parts are, for example, snap-in recesses of window catches / door catches, overrun parts for night ventilation with locking surfaces arranged in such a way that the sash frame is only kept open a few millimeters, overrun parts between the frame and sash frame in order to raise them to the normal position when the sash frame is closed.

In all cases, a pairing of such functional elements with counter-functional elements is provided between the frame and the casement of the window / door, e.g. a pair of run-up bevels with an associated sliding surface, a pair of locking recess with an associated spring-loaded locking ball, a stationary electrical contact in connection with an associated movable contact or the like.

The pairings of such functional elements always require a precise relative position to one another so that the intended function can be performed when the sash frame is closed or opened.

The requirement for precise assembly requires the individual functional parts to be positioned with millimeter precision.

For this purpose, numerically controlled fitting setting machines are increasingly used in window construction, which is known per se.

Nevertheless, the assembly effort for such functional parts is high. In particular, the assembly positions of the different functional parts are not standardized. The setting machine must therefore be programmed accordingly for each functional part.

Such functional elements in the form of vertical guide elements are known in a special embodiment. They are used in particular on turn-tilt windows / doors and are used to raise the casement when the window / door is closed so that the casement easily fits into the frame.

Basically, such sashes are padded with the installation of the glass panes, that is, aligned with respect to the outer edge of the glass panes. However, it is neither possible to avoid play between the alignment blocks and the outer edge of the glass pane, nor is it possible to fit the blocks without play.

Therefore, there will always be a lowering of the casement during the lifespan of such windows / doors, so a jamming is to be expected, this jamming should be eliminated.

For this purpose, pairings of run-up surfaces and run-on supports are known, which sit between the frame and the casement. However, this creates the basic problem of precise positioning, since the vertical positive guidance of the casement must take place in the millimeter range.

It is not important in the context of the present invention whether the vertical guide element is seated on the frame or on the sash frame and, correspondingly, the run-on support on the sash frame or frame. Alone the important feature is that the run-up support should be movable relative to the vertical guide element and should slide thereon under a predetermined lifting movement.

The requirement for a lifting movement in the millimeter range therefore always caused difficulties because the positioning of the vertical guide element relative to the run-up support should ideally take place with the window / door closed, but in this position the adjustment parts are not accessible.

The object of this invention is to develop the pairing of function elements assigned to one another in such a way that the risk of incorrect assembly is reduced with a simplified design.

This object is achieved in the known functional elements by the features of claim 1.

The essential aspect of the invention is based on the fact that one and the same base part can always be used for a large number of different functional parts. The base part has insertion openings, mounting surfaces, attachment points for the corresponding functional parts. While the base part is set precisely in the millimeter range by numerically controlled machines, the subsequent assembly of the functional parts can take place in assembly line production.

The invention therefore goes the way that first a base part is created, which has mounting points for a variety of different functional parts, that the base part can be used as a universal holder for different functional parts, that the base part due to known attachment points on the sash or frame with little programming Effort can be assembled and that, in combination with these features, incorrect fitting of the individual functional parts in assembly line production is impossible.

From the development according to claim 4, there is the advantage that only a single holder is provided for both right-hand and left-hand mounting. This bracket can therefore be used regardless of the stop side of the casement. Only the plug-in part with the run-up surface can be produced in both right-hand and left-hand versions. However, since this is preferably an inexpensive molded part - e.g. made of plastic or die-cast zinc -, which is unmistakably suitable for right-hand or left-hand operation in terms of assembly, can be assumed to be practically error-free.

Since the holder is symmetrical with respect to a horizontally lying axis transversely to the frame spar or to a corresponding horizontal plane, no errors can be made when mounting the holder. In particular, the bracket can be attached to the frame using numerically controlled machines. In order to prevent further confusion, the plug-in part should be designed so that either the plug-in part is horizontally symmetrical or that incorrect installation of the plug-in part is technically impossible. The last requirement can be achieved, for example, via cross sections of the plug-in part, which can only be assembled in a single correct manner.

Another essential aspect of the invention is also based on the fact that the vertical guide element is involved in the burglary protection of such windows / doors.

For this purpose, it is first proposed to let the ramp surface start with a gently rising ramp to initially lift the window / door with gentle force during the closing movement.

After the specified lifting position has been reached, the run-up slope should change into a horizontal locking surface. The sash of the Window / the door only guided and this without lifting.

The holder can be particularly advantageously designed as a horizontally symmetrical closing part on the window frame of the window / door. In this case, the closing part also takes on the additional function of lifting the casement when the window / door is closed. At the same time, however, when the window / door is closed, an additional intimate connection between the locking part and the locking bolt of the window frame / door frame can be guaranteed. Due to the form-fitting contact between the run-up support and the run-up surface, the locking bolt inserted into the locking part can form an abutment with respect to the run-up support when the window / door is closed. The locking part is therefore securely clamped between the locking pin and the run-up support.

Additional security can be achieved when using so-called mushroom bolts, which grip behind the closing part in a mushroom shape, while at the same time the run-up support rests on the run-up surface.

By using such a mushroom bolt in combination with an overrun support together on a single locking part, a double effect is exploited. This is because the locking part is not only clamped between the mushroom pin and the run-up support, but is even gripped behind. If necessary. the overrun support can also reach behind the locking part, in any case the plug-in part should reach behind the locking part.

In order to be able to use conventional technology, it is proposed to attach the overrun support to the cuff rail of the connecting rod fitting connected to the casement frame, with a distance to the associated locking bolt which, when the window / door is open, is greater than the entry distance of the locking pin slots on the locking part, but with closed window / door correspondingly lower.

All that is required is an additional attachment option for the overrun support on the faceplate of the espagnolette fitting. Since the faceplate is fixed to the sash frame and the locking part must be mounted on the bend frame for the associated locking bolt anyway, it is then only necessary to attach the insert part to provide a low-wear closing aid for the sash frame.

Additional security can still be achieved if the faceplate is additionally rigidly fixed between the overrun support and the locking bolt with respect to the casement. For example, screw holes can be made or similar measures taken.

View of the plug-in part of Figure 3 along the line IV-IV.

Unless otherwise stated below, the following description always applies to all figures.

The figures, in particular FIG. 1, show sections of a window / door. Such a window / door consists of a frame 1 and a sash frame 2 that can be tilted relative to it.

The frame is firmly anchored to the masonry. The sash frame can be rotated / tilted on the frame using appropriate hinges.

In the present case, the frame 1 carries a vertical guide element 3 on one of its vertical frame legs. The vertical guide element 3 has a horizontal between Cover frame 1 and sash 2 arranged ramp surface 4. The run-up surface interacts with a run-up support 5 on the casement corresponding to the vertical guide element 3. Since in the present case the vertical guide element 3 is attached to the frame 1, the overrun support 5 is rigidly attached to the casement 3. For reasons of clarity, only the area of the guide groove for the faceplate 15 is shown in the present case of the sash 2. In this regard, reference is made to the prior art.

It is now essential that the ramp surface 4 is attached to an insertion part 6, that the insertion part 6 can be inserted into a holder 7 from above, that the holder has symmetrical connecting regions 8 for the insertion part 6 with respect to a horizontal axis 9.

By combining these features, the bracket 7 can be attached to both the right vertical leg of the frame 1 and the left vertical leg of the frame. The holder 7 and the associated overrun support 5 are preferably provided on the handle side of the casement in order to carry out the intended lifting work there when the window / door is closed.

As can be seen from this in FIGS. 2 to 4, the plug-in part 6 is provided with an plug-in area which is introduced into a corresponding vertical slot in the holder 7. For attachment it can additionally be provided to provide a clip connection between the plug-in part 6 and the holder 7. Just as well, however, a clamp connection can also ensure a secure fit of the plug-in part on the holder due to the slight oversize between plug-in part 6 and holder 7. The insert part can also be inserted loosely and screwed to the frame.

It is also essential that the plug-in part 6 has a run-up slope 10 facing the wing frame to be closed, with which the run-up support 5 comes into contact when the wing frame is closed. While gliding on the ramp 10, the sash to be closed is raised according to the slope. An angle of the order of 10 to 25 ° is proposed as the helix angle. The ramp 10 then continues into a horizontally extending latching surface 11, on which the ramp support 5 comes to rest when the sash frame is to be closed. To avoid relative movement between the run-up support 5 and the plug-in part 6, the run-up support 5 can be a rotatably mounted roller.

A special feature is shown here, which consists in that the holder 7 is a horizontally symmetrical closing part on the frame 1. Such locking parts are known from EP 94 107 819. For all details not shown, reference is expressly made to this document. Such locking parts each have two opposing locking pin slots 12, in which a corresponding locking pin of the casement is inserted. Another special feature is that the overrun support 5 is arranged on the casement 2 in the present case and that the insert part 6 has been inserted into the locking pin slot 12 of the closing part 7 from above.

As shown particularly in FIGS. 1 and 2, the closing part 7 has the vertical locking pin slots 12 on its upper side and on its lower side. The locking pin slots 12 are provided symmetrically on the locking part with respect to the central horizontal plane. In the locking position of the casement 2, the mushroom bolt 13 moves into this locking pin slot 12 and engages behind the locking pin slot 12 in the locking position. At the same time, the overrun support 5 is supported on the opposite latching surface of the plug-in part 6. The sash frame is clearly clamped in the vertical direction and can no longer be moved, not even by force.

A secure attachment between the plug-in part 6 and the holder 7, which offers advantages with regard to the mushroom-like grip on the holder 7, lies in the fact that the extension of the plug-in part 6 to be inserted, as shown in FIG Mushroom-shaped cross-sectional profile 14, with which the insert part 6 engages behind the upper locking pin slot 12 and is firmly attached to it.

In order to enable the sash frame to be firmly clamped to the closing part 7, the overrun support is rigidly connected to the faceplate 15, as shown in particular in FIG. The run-up support 5 forms a distance from the mushroom pin 13 in the open position drawn with solid lines, which enables the window to be opened and closed. In the closed position shown with dashed lines, however, there is a clamping between the run-up support 5 and the associated mushroom pin 13. In any case, the vertical distance 19 on the entry side between the lower locking pin slot and the opposite latching surface 11 must be dimensioned such that the distance 17 or 18 between the two when the window is open Bump support 5 and mushroom pin 13 is larger than and smaller than when the window is closed.

In addition, Figure 2 shows that the ramp 10 merges into the horizontal locking surface 11 before the locking pin 13 has been moved into the retracted position (solid lines) in front of its associated locking pin slot 12.

Then the overrun support 5 is already supported on the horizontal plane of the latching surface 11, an unintentional opening of the casement does not occur.

Fig. 1 also shows that the faceplate 15 between the support 5 and the locking pin 13 to be attached to the casement. A corresponding screw hole 22 is used for this purpose. The drive rod 16, which runs longitudinally behind the faceplate 15, has a corresponding elongated hole at this point, so that the fastening screw between the run-up support 5 and mushroom pin 13 can penetrate the drive rod 16 without hindrance.

1 and 4 also show that the plug-in part 6 has a floor plan such that, when plugged in, it lies tightly against the associated side wall of the vertical frame leg. The insertion part 6 is therefore only for the left or right vertical frame leg. Confusion of such insert parts is therefore excluded. This is achieved in that the insert 6 has a recess 23 with which the longitudinal webs 24 of the frame leg correspond. The widened area of the insert part 6 is in any case completely on the facing side of the frame leg. In any case, the insert 6 is not horizontally symmetrical and can therefore only be provided for a predetermined stop side (right or left).

A major advantage of the invention is that the plug-in part 6 provides an easily replaceable wear part, which can be easily replaced if necessary.
