EP0816609A2 - Combination of wing and fixed frame for windows and doors - Google Patents

Abstract

The window or door comprises fixed (3) and hinged (2) frames. An air gap (4) is formed between them on one of which is a lock mechanism (5) with a driving rod (6) sliding in the lengthwise direction between locked and free positions, the moving part of the lock mechanism is mounted on it. One or more pairs of locking wedges are mounted in the air gap one of them is fixed to one of the frames with the other coupled to the rod. In the direction of the locking position (13), the ramp face of the fixed wedge (17) slopes upwards, while that of the moving wedge (16) does so in the opposite direction. In the locked position the ramp faces are immediately opposite each other.

Description

The following invention relates to the combination of sash and window frame of a window / door according to the preamble of claim 1.

Such a combination is known from EP 0 761 920 A2 and is essentially characterized in that the sash movable along an axis relative to the frame is struck, the between in the air gap area Sash frame and window frame arranged the Sash frame either closed (= closed position) or opens the lock (= release position) so that the sash can be opened. For this it is generally known to guide the hardware in a hardware groove in the casement. The fitting carries the locking bolts which in Retract the locking pieces attached as soon as the fitting is in the locked position.

It is equally possible that the fitting is in a fitting groove of the frame and that the locking pieces are provided on the casement for this case.

Such windows / doors usually consist of Plastic hollow profiles that have the advantage of an inexpensive series production Offer. Such series production does it, however necessary that relatively large tolerances between the internal dimensions of the frame and the outer dimensions of the Casement frames are necessary. These tolerances serve under among other things, the different thermal expansion behavior to balance between sash and frame. While namely the frame is tied up in the masonry, is the Sash frame freely expandable. Even in the worst case must be clamped between the sash and frame be avoided.

On the other hand, one naturally strives to achieve these tolerances to keep it as small as possible and separate guide elements to be provided between the casement and the frame, despite to achieve the most exact fit possible. For this purpose, ram blocks are known, for example serve to bridge the tolerances and for this purpose precise guidance when closing the window sash between the casement and frame.

Such trestles are in conventional windows quite suitable to take on managerial roles at Arched windows, however, make these headrests practical do not use because the exact positioning is not is possible.

It is therefore an object of this invention, the known Combination of casement frame and window / door frame so that regardless of the direction of the Frame spars of the frame and the sash a positive horizontal and vertical all-round connection between Sash frame and window frame are created. The solution to this Task results from the features of claim 1.

The advantage of the invention is that such a designed door / window designed in such a way offers increased security against break-ins.

This advantage is achieved in that in the rebate area between sash frame and window frame tolerance bridging and the movement of the fitting in and out of engagement pairs of locking wedges to be brought are provided, those in the release position are mutually free run past each other and one in the closed position positive connection between sash frame and frame produce.

The number of pairs of locking wedges can be in Depending on the window size can be specified. Usually it is sufficient to put between 1 and 3 on each frame leg To provide pairs of locking wedges.

In this way there is a relative movement between sash and frame reliably with the window closed prevented because the pairs of locking wedges one continuous rigid connection between sash and Create frame.

Even under extreme violence with conventional lever tools (e.g. screwdriver) holds the positive Compound between the sash and frame, so that the Engagement between locking bolts and locking pieces cannot be affected.

In order to solve this interference by external force can, the casement must have a frame can perform certain relative movement, which is due to the positive engaging pairs of locking wedges in the locking position of the fitting is reliably prevented.

It is only important for the invention that that the wedge surfaces involved in the closed position directly opposite. A certain air gap between the two wedge surfaces is entirely permissible. The air gap can e.g. 1-2 mm. It is important that the sash compared to the frame a limited to this air gap Relative movement can execute that relative movement, however limited by positive engagement of the wedge surfaces remains.

If you want to achieve that the wedge surfaces involved are practically form-fitting in the closed position, on the one hand, this can be done by positioning with millimeter precision the locking wedges are achieved relative to one another, on the other hand, there is a further training course in which at least one of the locking wedges is longitudinally displaceable is stored so that he is in the process of the fitting in the locking position relative to the other locking wedge is not moved more. The fitting with the locking bolt is, so to speak drove past with these relative to the locking wedges (1st variant) or drove past them (2nd variant).

Because the power transmission between the two wedges The locking wedges can be adjusted solely to compressive forces simply place on your assembly pad. The The mounting base is either the connecting rod or the faceplate of the fitting or the corresponding contact surface of the frame.

In the case of longitudinally movable locking wedges additionally proposed this into a spring force To keep the end position on the stop, in which it is in a positive Make contact with the other locking wedge. When opening the locking wedges the window / door becomes a precisely defined separation point generated between the locking wedges on both sides.

This is achieved in that the longitudinally guided Locking wedge when the two locking wedges move apart suddenly runs against the attack. In this position it stops while the second wedge continues becomes. The corresponding ones separate Wedge surfaces and the window sash can be opened.

An additional development of the invention provides that the locking wedges on their facing wedge surfaces have a tongue and groove combination running in the longitudinal direction. In this way, a two-dimensional bondage between Sash frame and frame achieved, the interlocking Tongue and groove combination forcibly initiated transverse movements of the casement and in the on-site fixed dowel frame transmits.

The wedges of this invention can be used as inexpensive individual parts are manufactured. Because the wedges essentially only have to be able to withstand compressive forces they consist of simple plastic injection molded parts, which in simple way compared to the fitting or the corresponding one Frame spar can be riveted.

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

The figures, in particular Fig. 1, shows a window 1, consisting of sash 2 and frame 3. The inside Sash frame is cut open so that the fitting 5 can be seen, which is in the air gap area 4 between Sash frame 2 and frame 3 is located there in the longitudinal direction between a closed position 13 and a release position 14 is movable.

Only the drive rod 6 of the fitting 5 is shown. Such fittings usually also have a Face plate on which the fixing of the drive rod 6 in a fitting groove provided for this purpose. For understanding However, the invention is not important.

The drive rod 6 is provided with locking bolts 7. The locking bolts are immediate with the movement of the drive rod and coupled directly. Drive the locking bolts 7 in locking pieces 8, which with respect to the case shown of the surrounding frame are fixed.

A gear serves to set the fitting 5 in motion 9. The gear 9 has a gear 10, the inner square 11 coupled with the window handle / door handle becomes. Turning the window handle / door handle will Gear 10 is set in motion and drives the rigid connected to the drive rod 6 rack 12.

The associated vertical drive rod 6 of the fitting 5 is set in vertical up and down movement. To couple this movement, they are arranged in turn Driving rods 6 with one another via so-called corner deflections 15 coupled. In this regard, reference is made to the prior art (see e.g. Pax brochure).

It thus arises in the air gap area 4 between the casement 2 and frame 3 a coupled chain from drive rods 6, which together either only clockwise or be driven counterclockwise.

The locking bolts 7 are either in the locked position 13 brought to the locking pieces 8 or in release position 14, so that the sash 2 is then opened can be.

It is now essential that in the area of the air gap 4 between Casement 2 and frame 3 at least a pair of Locking wedges 16, 17 are provided, which are in the locked position 13 are directly opposite with their wedge surfaces.

As can be seen from the broken line, drive the immediately opposite in the closed position Wedge surfaces until the release position is reached 14 of the fitting 5 apart so that they are mutual are disabled.

Each pair has one of the locking wedges with the Drive rod 6 of the fitting 5 connected. This wedge 16 therefore performs a movement identical to the drive rod movement out. The other of the locking wedges 17 is here with the Frame 3 firmly connected and positioned on the frame so that with its wedge surface the other locking wedge 16 is immediately opposite as soon as the closed position 13 has been reached.

The two locking wedges correspond in such a way that the wedge surface of a locking wedge, which with respect the fitting 5 is independent (here locking wedge 17) in Direction to the closed position 13 increases and that the wedge surface connected to the drive rod 6 of the fitting 5 Locking wedge (here locking wedge 16) against the direction to the closed position 13 also increases.

In this way, the pair of locking wedges 16.17 when the drive rod 6 moves in the direction of the closed position 13 move together and separate in the opposite direction. In addition, it is shown that each frame spar here only a single pair of wedges are provided is.

However, an arrangement is expediently preferred, where each pair of wedges are practically opposite to a locking pair consisting of locking bolt 7 and Locking piece 8 is arranged.

In this way you can use the smallest lever arms Tearing open the engagement between locking bolt 7 and locking piece 8 on the opposite support of the Prevent locking wedges 16, 17 reliably.

The relative positioning of the associated locking wedges can take into account that they are in their positive position practically with the taking of the closed position 13 the drive rod 6 come.

Here, however, is positioning with millimeter accuracy of the locking wedge 17 struck on the frame 3 necessary because the locking wedge connected to the drive rod 16 is practically immovably riveted to it.

Another way to get a positive investment two locking wedges in the locking position of the drive rod to achieve is that of the locking wedges 16, 17 along at least one from a predetermined position 19 a path is mounted longitudinally displaceable, which is at least so large that this locking wedge 17 or 16 (see Fig. 2a and Fig. 2b) from the positive contact of his Wedge surface on the wedge surface of the other locking wedge (= Positive locking position) remains relative to this until the Drive rod 6 has reached the closed position 13.

According to Fig.2a, this can be achieved in that the Locking wedge 17 on a linear bearing there 18 is mounted and held in a stop position 19 in which he receives the incoming wedge 16, which is connected to the drive rod 6, expected.

As soon as the two locking wedges 16, 17 in positive mutual investment, they move together with the drive rod 6 until it is in the closed position 13th brought.

This also applies analogously to the embodiment according to 2b, where the longitudinally slidable locking wedge 16th sits on the drive rod 6.

In addition, it is shown that the longitudinally movable locking wedge 17 and 16 respectively under the influence of a return spring 20 is in the stop position 19 as long as the one in question Locking wedge outside of the positive engagement his partner is.

While in Fig. 2a the linear bearing 18 from a rolling element bearing 21 exists, with the advantage of more extensive In the case of the Fig. 2b a slide bearing 22 is provided. Such slide bearing 22nd consists of a on the underside of the locking wedge 16 provided contact surface 23, which on the surface of the associated Fitting 5 slides. The wedge 16 penetrates the drive rod with a guide web 24 which through the intended longitudinal slot 25 of the drive rods goes through and behind the drive rod 6 with a Extension 26 hooked to prevent the wedge 16 from falling out to avoid.

In addition to what has been said so far, it is also possible to store both locking wedges in a longitudinally displaceable manner, which would correspond to a combination of FIGS. 2a and 2b.

As additionally shown in FIG. 3, the locking wedges 16, 17 on their facing wedge surfaces in the longitudinal direction have running tongue and groove combination 27; 28. For this one of the locking wedges (e.g. 16) with a groove 27 provided in which groove 27 an associated tongue 28 of the other Locking wedge 17 engages. In this way, one two-dimensional definition of those in the positive connection Locking wedges 16, 17 achieved so that not only the relative Play between sash 2 and frame 3 is bridged, but also a violently initiated Transverse movement of the casement safely intercepted becomes.

A further reduction in the remaining degrees of freedom can be achieved in that the tongue and groove combination is dovetailed. To this Way is in addition to the rear locking bolts 7 also a pull-out protection in the form-fitting engagement located locking wedges 16, 17 achieved. So consequently also pulling the locking wedge pairs 16, 17 apart prevented.

To bridge the naturally to be considered Tolerances can also be provided that the tongue and groove combination converges in the direction of entry 31. The leading movement therefore hits during the entry movement 31 narrow side of the spring 28 on the approached wider opening of the groove 27. With increasing entrance depth the side walls involved get between groove 27 and Spring 28 increasingly together until finally ideally one positive side contact between tongue and groove complete entrance depth comes about.

Of particular advantage is the fact that these couples of locking wedges 16, 17 also practically closing points between Sash frame and frame form so that these pairs 16.17 in principle also instead of locking bolts 7 and Locking piece 8 can be used.
