Abstract

The invention relates to a fitting (28) for attaching a movable and tiltable leaf to a fixed frame. The fitting (28) preferably has a movably arranged or designed bypass element (64). The fitting (28) is designed to position the leaf farther away from the fixed frame in the open position, in which the leaf can be moved, than in the tilted position, in which the fitting (28) is latched. The latching process in the tilted position is preferably carried out by engaging behind the latching element (58) of the fitting (28), in particular by covering the latching element. A spring element portion (62) of a spring element (60) of the fitting (28) can be supported on the bypass element (64) in the open position. The bypass element (64) is preferably moved towards the latching element (58) upon transitioning from the open position to the closed position in order to reduce the gap between the bypass element (64) and the latching element (58). The reduced gap at least prevents the spring element portion (62) from engaging behind the latching element (58). In this manner, the latching strength of the fitting (28) is at least reduced.

Description

In the Kippstelluno lockable and yet easily movable fitting for a window or a door when sliding-closing

The invention relates to a fitting for the unilateral connection of a wing to a fixed frame of a window or a door. The invention further relates to a window or a door with such a fitting. The invention further relates to a method for opening and closing a wing of a window or a door by means of a fitting.

Wings of windows or doors tend in the tilted position of the wing to hit due to drafts and / or due to an unfavorable located center of gravity of the wing, For example, the wing may tend to fall in far out of glazing in the tilted position.

In order to prevent the closing or slamming of the wing in the tilted position, fittings have become known which lock the wing in the tilted position. Corresponding fittings or locking devices for turn-tilt windows are known from DE 80 23 717 U l, DE 75 20 486 U l, DE 36 19 682 AI, DE 102 22 464 AI and DE 39 04 210 AI become.

Furthermore, EP 0 231 498 A2 discloses a fitting for a tiltable and movable relative to the fixed frame wings, wherein the fitting has a locking device. However, it is problematic to provide a locking device for a tiltable as well as off the fixed frame and sliding wings. For when the wing is to be closed by its parked from the fixed frame position, interfere with the hooking of the wing in the catch (the tilting position) when closing the wing. When closing the wing from its parallel parked position of the closing process should be as smooth and trouble-free as possible.

Object of the present invention is therefore to provide a fitting for connecting a tiltable and the fixed frame off sliding sash ready, which allows both a locking in the tilted position and easy closing from the parked position. The object of the invention is furthermore to provide a window or a door with such a fitting. It is another object of the invention to provide a corresponding method for opening and closing a wing.

This object is achieved by a fitting according to claim 1, a window or a door according to claim 12 and a method according to claim 13. The dependent claims give preferred developments again.

The object of the invention is thus achieved by a fitting for one-sided, in particular top-side, connection of a wing to a fixed frame of a window or a door, wherein the fitting allows the successive positions: a. A closed position, in which the wing rests in the region of the fitting on the fixed frame and the fitting is closed; b. a tilted position in which the fitting is opened to the wing, in particular on the upper side or underside, off the fixed frame, wherein the fitting is locked in the tilted position against a closing movement of the wing; c. an open position in which the fitting is further open than in the tilted position, so that the wing is parked in the region of the fitting further from the fixed frame than in the tilted position, wherein the open position enables a displacement of the wing, in particular parallel to the fixed frame; d. the closed position according to point a.

The fitting has a spring element with a spring element section, a latching element and a bypass element. In the tilted position, the spring element section engages behind the latching element and thereby enables the latching of the wing. The fitting is designed such that it at least less strongly locked when moving from the open position to the closed position by an indirect or immediate operation by the bypass element as in the tilted position, so that the wing is easily moved from its open position to the closed position.

The bypass element can deflect the spring element section indirectly or directly in order to reduce or cancel the latching of the spring element section provided on the latching element in the closing movement of the fitting from the open position into the closed position. The fitting allows locking the wing in the tilted position, without a user having to do without the possibility of a comfortable closing of the wing from the parked position.

In the context of the present invention, the terms "closed position", "tilted position" and "open position" are analogous to the fitting and the wing used. However, it should be noted that although the fitting according to the invention for the one-sided connection of the wing on the tilted position of the closed position is movable to the open position, but not necessarily the wing. The wing is usually arranged on other fittings on the fixed frame, that the wing from the closed position is movable either in its tilt pitch or in its open position. In this case, the wing is usually designed such that the wing plane is moved in the movement from the closed position of the wing in the open position of the wing parallel to the frame main plane of the fixed frame. The wing is placed in its open position, at least in the area of the fitting further from the fixed frame than in its tilted position. Thus, the fitting according to the invention is indeed moved over the tilt position of the fitting according to the invention during the movement of the wing from the closed position to the open position; However, at the time when the fitting according to the invention is in the tilted position, the wing is usually not in its tilted position, but it is just on the way to its parallel parked open position of the wing. In other words, the wing, when the fitting according to the invention is in the tilted position, either actually in its tilted position or he is on the way to its more open open position.

The terms "bottom", "top", "horizontal", "vertical", etc. refer to the assembled state of the hardware on a window or door.

The "hysteresis" of the fitting according to the invention, ie a movement of the fitting from the closed position into the open position, which differs from the movement from the open position to the closed position, can be realized mechanically in different ways are particularly simple and thereby cost-effectively produced. In one embodiment of the invention, the latching element and the bypass element are movable toward each other, in particular to each other to be displaced. Preferably, the latching element and the bypass element are movable towards each other to the mutual contact and / or both movable together.

The spring element section can be supported in the open position on the bypass element. Together with the bypass element, the spring element section can thereby be moved toward the detent element during the movement from the open position into the closed position, so that the spring element section engages behind or does not engage behind the detent element during the transition from the open position to the closed position.

The locking element may be part of a control of the fitting or, in particular rigid, be arranged on the control. The control element is preferably designed in the form of a slide. The control can be arranged displaceably on a rail of the fitting. The control may be forcibly controlled, i. the control can be designed to forcibly perform a movement by the opening and closing movement of the fitting.

In a particularly preferred embodiment of the invention, the fitting has a damper and / or a spring in order to be able to move the wing comfortably. The damper and / or the spring is / are preferably arranged or formed at one end directly or indirectly on the control element. Alternatively, the damper and / or the spring can be arranged on a rail of the fitting. The control thus has a Synergy effect, since it is provided both for connection of the damper and the spring and as part of the locking device according to the invention.

The positive control of the control is preferably carried out by a control arm, which is part of a Ausstellschere of the fitting. The control arm is indirectly or directly hinged connected to a stay of Ausstellschere.

The bypass element may be designed to be movable in the form of a slider and movable relative to a rail of the fitting, in particular displaceable. The bypass element can, except for the influence of the spring element section, freely movable between attachment points of the fitting, in particular be displaced. The contact points of the fitting are preferably formed by a stop of the, in particular displaceable, control element and the latching element.

To ensure that the spring element section does not slip off the bypass element during the movement of the fitting from the open position to the closed position, the bypass element can have a first projection which is at least partially engaged behind by the spring element section during at least partial movement of the fitting from the open position into the closed position.

In addition, for reasons of symmetry, the bypass element can have a second projection in order to avoid incorrect assembly of the bypass element. In a further preferred embodiment of the invention, the latching element and / or the bypass element has / have a flat section for supporting the spring element section. The flat portion or the flat portions enable / allow a slight displacement of the spring element portion on the locking element or on the bypass element. The slight displacement of the spring element section relative to the bypass element is preferably limited by at least one, in particular both, of the projections described above.

The mounting of the bypass element is facilitated if the bypass element is designed mirror-symmetrically. The mirror plane preferably extends perpendicular to the longitudinal axis of the bypass element.

The bypass element is preferably arranged so as to be easily displaceable relative to the control element and / or to a rail of the fitting. The bypass element may be latched to a groove in a rail of the fitting. Alternatively or additionally, the bypass element can be guided in a ut a rail of the fitting and locked in a groove of the control.

On the rail of the fitting, the control can be arranged or formed. The control element is preferably movable relative to the rail, in particular displaceable, formed.

On the rail of the fitting, the spring element can be arranged or formed. Preferably, the spring element is designed in the form of a spring arm, which is fastened to the rail. The fitting may have at least one slider to move the wing in the open position, in particular parked parallel to the fixed frame.

The object of the invention is further achieved by a window or a door with a fixed frame, a relative to the fixed frame movable wings and a previously described fitting for one-sided, in particular top-side, connection of the wing to the fixed frame.

The object of the invention is further achieved by a method for moving a wing of a window or a door, in particular a previously described window or door described above, by means of a previously described fitting, from its closed position to the open position and back to the closed position, the Method comprises the following method steps:

A. Moving the fitting from a closed position to a tilted position, wherein the fitting locked in the tilted position to complicate at least one movement of the fitting back into the closed position;

B. Moving the fitting from the tilted position to an open position in which the fitting stops the wing further from the fixed frame than in the tilted position;

C. moving the fitting from the open position to the closed position, wherein the fitting in the above-described position of the tilted position at least less locked in order to facilitate the closing movement of the wing. The fitting for carrying out the method according to the invention preferably has a bypass element and a spring element section of a spring element, wherein the bypass element and a latching element when moving the fitting from the open position to the closed position toward each other, in particular shifted towards each other, so that the movement of the spring element section is facilitated on the locking element in the further closing of the fitting. Preferably, the locking element moves to the bypass element and moves, in particular shifts, then the bypass element. The spring element is preferably arranged stationary.

Preferably, the spring element portion is moved when moving the fitting from the tilted position to the open position on the bypass element, in particular pushed. Alternatively or additionally, the bypass element can be displaced by the spring element section from the latching element when moving the fitting from the closed position into the tilted position.

Further features and advantages of the invention will become apparent from the following description of an embodiment of the invention, from the claims and from the figures of the drawing, which shows essential to the invention details. The features shown in the drawing are shown such that the features of the invention can be made clearly visible. The various features may be implemented individually for themselves or for a plurality of combinations in variants of the invention. Show it :

Closed position, wherein the representation according to Figure 4f corresponds to the representation of Figure 4a.

Figure 1 shows a door 10 with a fixed frame 12 and a wing 14. The wing 14 is supported on its underside via a carriage assembly 16. When the wing 14 is turned off the fixed frame 12, it can be displaced in the direction of an arrow 18. The displacement of the wing 14 takes place in particular parallel from the fixed frame 12. The carriage assembly 16 has a first carriage 20 and in particular a second carriage 22. The carriage 20, 22 run on a track rail 24th

The wing 14 has a handle 26. The handle 26 is movable in a first handle position 26a, in which the wing 14 is in the closed position. In the closed position, the wing 14 is firmly locked to the fixed frame 12. If the handle 26 is pivoted into a second grip position 26b, the wing 14 can be turned off the fixed frame 12 and displaced in the direction of the arrow 18. The wing 14 is then in an open position. If the handle 26 in contrast pivoted from the first handle position 26a in a third handle position 26c, the wing 14 is on one side, here on its underside, not off the fixed frame 12. The wing 14 is then however on one side, here with its top, movable away from the fixed frame 12 so that a user can move the wing 14 in a tilted position. This side of the wing 14, here the top of the wing 14, is less far from the fixed frame 12 in the tilted position than in the open position. The one-sided connection of the wing 14 to the fixed frame 12, here at the top thereof, is effected by a fitting 28.

If the wing 14 is in the closed position, the fitting 28 is also in the closed position. The wing 14 is in the tilted position, also the fitting 28 is in the tilted position. If the wing 14 is moved from the closed position to the open position, the fitting 28 passes the tilted position. At this time, however, the wing 14 is not in its tilted position because it is parked parallel to the fixed frame 12. More precisely, the wing 14 is only in the region of the fitting 28 in the tilted position, but not in total, since it is also parked on its, the fitting 28 opposite side, from the fixed frame 12. The closing of the wing 14 from the open position to the closed position also takes place at the frame main plane of the fixed frame 12 parallel plane of the wing fourteenth

FIG. 2 shows the majority of the fitting 28. The fitting 28 has a first rail 30 and a second rail 32. The first rail 30 is movable to move the wing 14 (see Figure 1), here slidably disposed on the fixed frame 12, which is only partially shown in Figure 2 for reasons of clarity. The second rail 32 is fixed on one side, here on the upper side, of the wing 14 (see FIG. 1).

To stop the wing 14 (see Figure 1) from the fixed frame 12, the fitting 28 has a first extension arm 34 and in particular a second Extending arm 36. To guide the first Ausstellarms 34, a first control arm 38 is provided. To guide the second extension arm 36, a second control arm 40 is provided. The first extension arm 34 together with the first control arm 38, a first Ausstellschere 42. The second extension arm 36 forms with the second control arm 40, a second Ausstellschere 44. The second control arm 40 is further formed for locking the first fitting 28 in the open position. For this purpose, a first control pin 46 engages in a latching recess 48, which is preferably formed in the second control arm 40. If the first control bolt 46 is latched in the latching recess 48, this latching can only take place by actuating the second control arm 40, here by actuating a second control bolt 50.

In contrast, the fitting 28 is not in the open position, but, as shown in Figure 2, in the tilted position, so the first control pin 46 does not lock in the recess 48th Because the fitting 28 is less widely opened in the tilted position shown in Figure 2 as in the open position. The second Ausstellschere 44 thus does not prevent slamming of the wing 14 (see Figure 1) from the tilted position to the closed position. The wing 14 (see Figure 1), however, may tend to move to the closed position due to an unfavorable center of gravity and / or due to drafts.

In order to prevent or complicate this movement from the tilted position to the closed position, a locking device for the tilted position is provided according to the invention (the fitting 28 is shown in FIG. 4b in this latching tilting position). It should be noted that a conventional locking of the fitting 28 in the tilted position would hinder or complicate the comfortable closing of the fitting 28 from the open position to the closed position. It is therefore an object of the invention to provide a fitting 28, on the one hand, the latching in the tilted position and on the other hand, a allows smooth closing of the fitting from the open position to the closed position.

FIG. 3 a shows a partial view of the fitting 28 in the region of the first deployment scissors 42 (see FIG. 2). It can be seen from FIG. 3 a that the first rail 30, the first control arm 38, the first extension arm 34 and the second rail 32 are preferably arranged offset vertically relative to one another. Fixed to the first rail 30 is a slider 52 for facilitating the sliding of the fitting relative to the fixed frame 12 (see FIG. 1). The first control arm 38 is arranged directly or indirectly on a control element 54. The control element 54 is movable, here displaceable, arranged on the first rail 30. When opening and closing the wing 14 (see FIG. 1), movement of the first deployment arm 34 causes movement of the first control arm 38, which in turn moves the control member 54 relative to the first rail 30.

At the control element 54, a damper and / or a spring (not shown) may be arranged or formed at one end. At the change end, the damper and / or the spring is / are preferably arranged or formed on the first rail 30. A movement of the first control arm 38 thus also causes an actuation of the damper or the spring.

The control element 54 has a boom 56. At the free end of the boom 56, a locking element 58 is provided. The control element 54 may be designed in several parts. Preferably, the control element 54, as shown in Figure 3a, in one piece, ie integrally formed with the locking element 58. Fixed to the first rail 30, a spring element 60 is arranged. The spring element 60 is designed in the form of a spring arm. The spring element 60 has a spring element section 62 in the region of its free end. In the open position of the fitting 28 shown in FIG. 3 a, the spring element section 62 is braced against a bypass element 64.

FIG. 3b shows the fitting 28 according to FIG. 3a in a further view. FIG. 3 b illustrates that the bypass element 64 is arranged with at least one latching section 66, preferably with two latching sections (as shown in FIG. 3 b), displaceably in a groove 68 of the first rail 30.

The components shown in Figures 3a and 3b form an embodiment of a locking device in the tilted position of the fitting 28, which does not hinder a closing of the fitting 28 from the open position to the closed position. The function of this locking device will be explained below with reference to FIGS. 4a to 4f:

FIG. 4a shows the fitting 28 in the closed position. The spring element section 62 does not engage behind the latching element 58. In the closed position, the spring element section 62 is preferably spaced apart from the latching element 58. The bypass element 64 is movable, here displaceable, between the latching element 58 and a stop 70 of the control element 54.

FIG. 4b shows the fitting 28 in the tilted position. The spring element section 62 has moved past the latching element 58 during the transition from the closed position (see FIG. 4 a) into the tilted position. In the present case, the spring element section 62 has the latching element 58 run over. If the bypass element 64 bears against the latching element 58, the spring element section 62 displaces the bypass element 64 after the latching element 58 has moved past the spring element section relative to the spring element section 62. The spring element section 62 now engages behind the locking element 58. This rear grip secures the wing 14 (see FIG. 1) against an unwanted return movement into the closed position, ie. against a slam. In the present embodiment, the bypass element 64 bears against the stop 70 of the control element 54. The spring element section 62 can thus not further displace the bypass element 64. In the embodiment shown, therefore, there is also a resistance of the fitting 28 against further opening. Between the locking element 58 and the bypass element 64 remains a gap S, in which the spring element section 62 can dip in the tilted position.

FIG. 4c shows the fitting 28 in the open position. The resistance to further opening of the fitting 28 described with reference to FIG. 4b can easily be overcome. The resistance of the spring element section 62 relative to the latching element 58 or the bypass element 64 can be adjusted by a corresponding design of the bevels of the latching element 58, of the spring element section 62 or of the bypass element 64.

The bypass element 64 has a first projection 72 and a second projection 74. The spring element section 62 is movable between the projections 72, 74, here displaceable. Between the projections 72, 74, the bypass element 64 is formed flat. This facilitates the displaceability of the spring element section 62 relative to the bypass element 64. The second projection 74 prevents a misassembly of the bypass element 64 for reasons of symmetry. The function of the first projection 72 is explained below with reference to FIG. 4d. FIG. 4d shows the fitting 28 during the movement from the open position (see FIG. 4c) into the closed position (see FIG. 4f). It can be seen from a comparison of FIGS. 4c and 4d that the control element 54 moves away from an attachment point 76 of the spring element 60 when the fitting 28 is closed. As a result, the detent element 58 comes into abutment with the bypass element 64. As a result, the bypass element 64 is likewise moved away from the attachment point 76 of the spring element 60. The first projection 72 prevents the spring element section 62 from slipping down from the bypass element 64 in a slight manner and reaching into engagement with the latching element 58. The gap S (see FIG. 4b) was at least reduced, in particular completely closed, by the closing movement of the fitting 28 from the open position (see FIG. 4c) into the closed position (see FIG. 4f) (as shown in FIG. 4d).

FIG. 4e shows the fitting 28 during the further closing operation. From a combination of Figures 4d and 4e it can be seen that the spring element portion 62 passes directly from the bypass element 64 to the latching element 58, in particular reaches a plane of the latching element 58, without engaging behind the latching element 58. The fitting 28 can thus reach the closed position (see FIG. 4f) from the open position (see FIG. 4c) without latching action.

FIG. 4f shows the fitting 28 in the closed position. Figure 4f illustrates that the bypass element 64 is formed mirror-symmetrically to a mirror plane 78. This facilitates the mounting of the bypass element 64 to the first rail 30, as a fitter must pay less attention to the orientation of the bypass element 64 during its installation. The upper level of a plate-shaped portion 80 of the bypass element 64 is aligned with the upper level of a plate-shaped portion 82 of the locking element 58. As a result, the closing movement of the fitting 28 can be made particularly uniform.

If a user moves the wing 14 (see FIG. 1) out of the closed position into the tilted position and back into the closed position, the fitting 28 maximally assumes the positions shown in FIGS. 4a and 4b. The spring element section 62 engages behind the latching element 58 in the tilted position (see FIG. 4b).

In contrast, when a user moves the fitting 28 from the closed position into the open position and back into the closed position, the fitting 28 passes through all the positions shown in FIGS. 4a to 4f. A latching of the fitting 28 does not take place, as can be seen in particular from a combination of FIGS. 4d and 4e.

Taking a synopsis of all the figures of the drawing, the invention in summary relates to a fitting 28 for connecting a displaceable and tiltable wing 14 to a fixed frame 12. The fitting 28 preferably has a movably arranged or formed bypass element 64. The fitting 28 is adapted to turn off the wing 14 in the open position, in which the wing 14 is displaceable, further from the fixed frame 12 than in the tilted position in which the fitting 28 is locked. The latching in the tilted position is preferably carried out by a rear engagement, in particular an overlapping, a latching element 58 of the fitting 28. A spring element section 62 of a spring element 60 of the fitting 28 may be supported in the open position on the bypass element 64. The bypass element 64 is preferably at the transition from the open position to the closed position to the locking element 58th moved to reduce a gap S between the bypass element 64 and the latching element 58. The reduced gap S causes at least a reduction of the rear grip of the locking element 58 by the spring element portion 62. As a result, the latching strength of the fitting 28 is at least reduced.
