Abstract

The invention provides a device for securing a window sash to the outer frame of the window so that, on the one hand the sash may be locked in a predetermined open position and on the other hand may be pivoted to open it fully. A single push-button serves both to disengage a catch in the predetermined open position and to release the sash for full opening.

Description

The invention relates to a device for determining a sash frame rotatable about an axis of rotation on a frame in a predetermined rotational opening position for a door, a window or the like, comprising
a display pocket which is articulated at one end to a first of two associated frame legs of the casement frame and the frame by a swivel joint and at its other end to the second of these associated frame legs by a swivel sliding joint with a fork-like slit,
Latching means which automatically immobilize the setting of the flap with respect to the frame legs when the sash frame coming from the closed position enters the predetermined rotational opening position,
and hand-operated solvents for these latching means.

Such a device is known from German utility model 84 17 729.

In the known arrangement, an opening of the casement is only possible up to the predetermined opening position. A further opening of the casement is in any case for the layperson, i. H. not easily possible for the resident of the apartment equipped with the window.

The invention has for its object to provide a device of the type described above, in which an opening of the casement into a further rotational opening position, in particular in a fully open position, is possible by simple conversion measures.

To solve this problem, the invention proposes
that the swivel joint is arranged on a sliding piece that is movable in the longitudinal direction of the first frame leg in a sliding piece guide,
that this slider is biased by spring means towards a basic position


that the swivel sliding joint in the closed position of the casement can be uncoupled in that, by disengaging the slider from its basic position against the action of the spring means, the flap is moved relative to the fork-like sliding slot.

The device according to the invention can be attached to a wide variety of types of windows, in particular simple rotating windows with a vertical rotating axis, tilting windows with a horizontal tilting axis, rotating tilting windows with a horizontal tilting axis and vertical rotating axis and swinging windows with a horizontal swinging axis. In all cases, the device can be arranged so that the axes of the swivel joint and the swivel sliding joint are parallel to the respective axis of rotation or tilting axis or swinging axis, but also such that the axes of the swivel joint and the pivoting sliding joint are substantially perpendicular to the axis of rotation or tilting axis or swinging axis of the casement.

A preferred embodiment provides
that the latching means are formed by a disengagement and latching cam arranged on the flap on the one hand and a cam engaging edge cooperating with this disengaging and latching cam on the slide guide on the other hand, with the pivoting movement of the flap around the swivel joint caused by the sash frame approaching the predetermined rotational opening position the interaction of the disengaging and latching cam and the cam engaging edge initially causes the slider to disengage from the basic position against the action of the spring means and only when the predetermined rotary opening position reaches the cam and cam engaging edge under the effect of the spring means returning the slider towards the basic position engage in mutual locking.

In this case, the locking can be released by moving the slider from the basic position by hand, counter to the action of the spring means.

The disengagement and latching cam can be carried out with a disengagement curve and adjacent to the disengagement curve of a latching trap, the disengagement curve when the sash is brought into the predetermined rotational opening position in cooperation with the cam engagement edge, which disengages the slider from the basic position against the action of the spring means and that When the predetermined rotary opening position is reached, the catch engaging edge picks up and the immobilization pocket is thus immobilized.

A simple embodiment for the swivel sliding joint consists of a fork-like open sliding slot of a fitting part fastened to the second frame leg on the one hand and a slot engagement bolt on the other, i. H. compared to the first frame leg freely movable end of the display pocket on the other hand. The slot engaging bolt can emerge from the open fork end if the slide is moved out of the basic position by hand against the action of the spring means.

An embodiment of the display pocket which is simple in construction and acceptable in terms of its space requirement consists in that two mutually parallel slats form the display pocket, these slats receiving the slider between them at one end of the display pocket and slot engaging bolts are connected at the other end. In this case, a rib having the sliding slot of the fitting part attached to the second frame leg can engage between the two slats.

At its end remote from the display pocket, the slider can be designed as a manually operable release button. This release button is available on the one hand to release the catch again in the locked predetermined open position of the casement, but on the other hand also to fully open the casement when the casement is in the closed position. H. to enable an opening beyond the predetermined opening position. This is a particular simplification in that one and the same manual actuator is available for two different functions.

In order to obtain a stable and aesthetically pleasing design, it is proposed that the slide guide comprises a rectangular, elongated housing which in the closed position of the casement receives the entire length of the opening pocket and has an opening in the longitudinal side wall for the opening of the opening pocket. The elongated housing then serves only as part of its length as a slide guide and on the rest of its length for covering and, if necessary, supporting the flap. In this case, an end edge of the opening close to the slider can be designed as a cam engagement edge.

In order to lock the sash frame in the predetermined open position and / or in the closed position and to be able to secure it against unintentional opening from the inside and / or from the outside, it is proposed that the slider can be locked in its basic position relative to the slider guide. The display pocket in the basic position of the slider can either assume a parallel position to the associated first frame leg corresponding to the closed position of the casement and can be fixed in this parallel position by the interaction of the disengagement curve with the cam engaging edge, or the display pocket can be in the predetermined rotational opening position of the casement by cooperation of the latch the cam engaging edge is immobilized. Such a lock is used, for example, to prevent children from accidentally opening the casement.

The block can e.g. B. be formed by a grub screw in the slider, especially one with an Allen key, which can be screwed into engagement with a corresponding opening in the slider guide.

With regard to the right and left usability of the device, it is proposed that it be designed symmetrically with respect to a plane of symmetry perpendicular to the axes of the pivoting and pivoting sliding joints.

With regard to a simple release access in the predetermined rotary opening position, it is advantageous if the slide guide can be fastened to a casement leg. However, it is also possible to attach the slide guide to a frame leg.

The device according to the invention is, in particular, independent of other parts of a fitting system also suitable for retrofitting, ie for retrofitting to a window or door.

To eliminate mounting difficulties for the slide guide in the area of the slide, it is proposed that a rivet penetrating the slide guide and the slide is provided to guide the slide and / or to restrict movement of the slide and / or to support the spring means, which rivet has a fastening screw for fastening the slide guide the respective frame leg. In this way, at least two functions are performed by one and the same part, namely the hollow rivet.

If the device is attached so that the axes of the swivel joint and the swivel sliding joint are parallel to the respective axis of rotation, the opening opening width can be varied without changing the device by changing the location of the device along the frame legs.

It is possible that a sloping edge is provided on a fitting part receiving the sliding slot adjacent to the open end of the sliding slot, which is in the area of the slot engagement bolt when the slide is in the basic position. This will make it easier to close the casement. It is not necessary to operate the slide manually to close it.

In Fig. 1 you can see a sash, which is generally designated 10 and a frame, which is generally designated 12. The two frame legs of the casement frame and the frame, which are remote from the axis of rotation, are designated by 10a and 12a, respectively. Between the frame legs 10a and 12a, a device 14 is provided for fixing the casement 10 relative to the frame 12, which allows a predetermined opening angle α to be set about the axis of rotation A-A.

According to FIG. 2, more details on FIG. 1 can be seen. On the outer frame visible surface 12b of the casement leg 12a there is a fitting plate 16 on the outer frame side, which carries a rib with a fork-like open sliding slot 18.

A housing 20 of approximately square cross section is fastened to the sash frame, specifically on the rollover peripheral surface 10b of the sash frame leg 10a. This housing 20 has an opening 22 in its side wall 24 facing the frame leg 12a.

In the housing 20, a slider 26 is slidably disposed. In Fig. 2, the slider 26 is in its uppermost position and can be pushed down from the basic position against the action of a helical compression spring. A flap 30 is articulated on the slide 26 by means of a swivel joint 32. The 5, consists of two lamellae 30a and 30b, which are supported on both sides of a downward extension tongue 26b of the slider 26 by stub shafts 32a, 32b on the slider 26. The stub shafts 32a and 32b together form the swivel joint 32. At their other end, the two slats 30a, 30b of the flap 30 are connected to one another by a slot engagement bolt 34 which engages in the fork-like open slot 18, the two slats 30a and 30b in FIG 2 are located on both sides of the rib 16. In FIG. 2, the sash frame 10 is fixed relative to the frame 12 in that, on the one hand, the slot engagement bolt 34 engages in the fork-like slot 18 and, on the other hand, the opening pocket 30 is immobilized in relation to the housing 20. A cam 36 is attached to the lamella 30b (the same applies to the lamella 30a) and has a disengagement curve 36a and a latching catch 36b. In Fig. 2, a cam engaging edge 38 which defines the upper end of the opening 22 in the side wall 24 is in engagement with the latch 36b. As long as the slide 26 assumes the basic position set in FIG. 2 under the action of the screw compression spring 28, the opening pocket 30 cannot be pivoted relative to the housing 20. This is the reason for the immobilization of the casement 10 in relation to the frame 12.

If you want to move the sash starting from the predetermined rotational opening position α according to FIGS. 1 and 2 in the closed position, you only need to press on the slider 26, whose upper end 26a is designed as a push button until the cam 36 with it Release curve 36a to below the cam engagement edge 38 has occurred, so that the opening pocket 30 can from now on be pivoted in the counterclockwise direction according to FIG. 2. If the sash frame 10 is then approached to the frame 12, the swivel bracket 30 rotates counterclockwise about the swivel joint 32. The pressure on the pushbutton 26a can stop after only a slight rotation of this type because the disengagement curve 36a has then come into engagement with the cam engagement edge 38. As the sash 10 approaches the frame 12, the disengagement curve 36a slides on the cam engagement edge 38, the position of FIG. 3 being reached. In this position according to FIG. 3, the slider 26 has returned to the basic position thanks to the shape of the disengagement curve 36a (see FIG. 3). In Fig. 3 it can be seen that in the closed position of the casement the slot engaging bolt 34 still engages in the fork-like open sliding slot 18, so that when the casement is reopened in relation to the window frame in the direction of the predetermined rotary opening position shown in FIGS. 1 and 2 as before there is the readiness for locking in the predetermined rotary opening position. 1 and 2, the disengagement curve 36a rolls off at the cam engagement edge 38, with the slide 26 initially being pulled down against the action of the helical compression spring 28 compared to the basic position according to FIG. 3, until Finally, the cam engagement edge 38 can fall into the latch 36b of the cam 36 and thus roll the slider 26 back into the basic position, whereby the setting according to FIG. 2 is reached again.

If intended, the window over that shown in Fig. 1 To open the predetermined rotational opening position α, this is possible by pressing the slider 26 downward from the position shown in FIG. 3 into the position shown in FIG. 4 before the start of the rotary opening of the sash frame. If you now start the rotary opening of the casement, the slot engagement bolt 34 can emerge laterally from the sliding slot 18, so that the sliding joint 34, 18 is uncoupled.

4 shows a through-bore 40 of the housing at the lower end of the housing 20 and a hollow rivet 42 penetrating the housing 20 at the upper end of the housing. The through-bore 40 and the hollow rivet 42 are intended for receiving fastening screws, with which the housing 20 is attached to the rollover peripheral surface 10b. The hollow rivet 42 passes through an elongated hole 44 in the slider 26. A bore 46 is made in the upper end of the slider 26 and is closed by a plug 48. Between the stopper 48 and the bore 46, the helical compression spring 28 is accommodated, which is supported at one end against a shoulder surface of the stopper 48 and at the other end against the rivet 42. In this way, the helical compression spring 28 looks for the slide 26 upwards slide into the position shown in Figs. 2 and 3. 4 and 5, however, the slider 26 is pressed against the action of the helical compression spring 28 down.

In the basic position of the slider 26 shown in FIGS. 2 and 3 there is a grub screw 50 accommodated within the slider 26 with an Allen head in alignment with a hole 52 in the housing 20. The grub screw can be screwed out so far with an Allen key that its outer end engages in hole 52. Then a displacement of the slider 26 from the basic position is no longer possible. This means that both the state according to FIG. 2 (casement frames in a predetermined rotational opening position α) and the state according to FIG. 3 (casement frame in the closed position) can be arbitrarily blocked.

From Figs. 2 and 3 it can be seen that a slope 16b is attached to the lower end of the rib 16a of the fitting part 16. 3 assumes its uppermost position, the slot engaging bolt 34 is at the height of the bevel 16b. This means that by pressing the casement 10 against the frame 12, the slot engaging bolt 34 can be brought into engagement with the bevel 16b. This also means that the slot engaging pin 34 exerts a pull on the deployment pocket 30 and on the slide 26, so that the slide 26 is pulled down with the deployment pocket 30 and the slot engagement bolt 34 engages in the sliding slot 18. After latching, the slider 26, the pop-out pocket 30 and the slot engagement bolt 34 return to the position shown in FIG. 3.
