Description

The invention relates to a fitting for a tilting and tilting movement of a wing of a building window or a building door according to the preamble of claim 1.

A fitting for an at least tiltable, parallel storable and parallel movable wing of a window or a door of the aforementioned type is already known from EP 0231498 B2 known. The fitting described herein has at the upper end of the wing two spaced, at least two rotatably mounted Ausstellarme, which are connected to a fixed frame, wherein the two Ausstellarme are coupled together by means of a link. The fitting is mounted on the frame as well as on the wing and the wing can be moved in front of the frame. In order to secure in particular the tilted or parallel parked position, located on each wing-side Ausstellarmende a locking device. This consists of a locking member, in particular a locking lug of the extension arm or and a locking element on the wing with a locking receptacle for the locking member. The locking element is made of plastic and the locking receptacle is located on a resiliently evading web of the locking member.

A disadvantage of the aforementioned embodiment is that the locking member is formed very expensive, which has a cost-intensive effect in the production. The locking member requires a relatively large space, which adversely affects the visual appearance. Furthermore, the locking member has no damping effect in the transition from the closed position into the tilted or parallel parked position of the wing, so that the wing goes unrestrained with its sash weight in the switching position described.

Such a fitting is further from the EP 1555368 B1 known. In this case, one of a frame parallel offable and laterally displaceable wings is provided, are hinged in which for an opening or tilting movement of a window or door leaf at the top of this wing two upper Ausstellarme, with its other end with one in a horizontal guide sliding slider are hingedly connected. The two spaced apart On the wing articulated bearing elements, pivotally carry a hinge pin on each a Ausstellarm.

The design contributes to the casement in the area of the bearing elements in the direction of the building inside due to the arrangement of the opening arms, which adversely affects the visual appearance. Furthermore, the embodiment has no latching or damping device for the tilted or parallel parked position.

The object of the invention is therefore to avoid the disadvantages of known fittings and to form a fitting of the type mentioned in such a way that at a low cost, with a simple installation and a visually pleasing appearance on the one hand a simple but effective damping in the desired Opening width of the wing is given and on the other hand a secure opening width is achieved.

The solution of this problem is achieved in a fitting according to the preamble of claim 1, characterized in that between the rivet and the bore, a radially deformable damping element is mounted.

Due to the configuration it is achieved that with the arrangement of the damping element within the pivot bearing in a bore of the extension arm of the bearing element little space is needed, which has an advantageous effect on the visual appearance. So that the extension arm has no further receptacle for the damping element to provide, the extension arm can be produced in advantageously cost-effective production of a strip material in the longitudinal punching process. Furthermore, the damping element made of a rubber or an elastically deformable plastic material produces a particularly smooth-running and low-wear working design. Due to the choice of material can be dispensed with an additional lubricant to minimize the frictional resistance in the operation of the fitting.

To make the damping element as simple and inexpensive as possible, it is provided that the damping element is a substantially flat annular Shaped body is having a bore. As a result, areas are provided on the damping element, which can deform under load.

In addition, the damping element causes the transition of Ausstellarms from the closed position in the tilted position of the building window or door first damping of the wing and a subsequently secured Ausstelllage, which is effective both in the tilted position as well as in parallel parked position and retain until There their position in a resting position unaffected.

A further development provides that the bearing element has a bearing plate as the main body, wherein a leg and a portion form an angle. The bearing plate is formed in cross-section L-shaped and surrounds due to their design, the edge of the upper horizontal spar of the sash. The leg is arranged on the voltage applied to the upper edge of the casement, the portion of the upper edge of the spar in the direction of the upper horizontal spar of the frame over an angle and rests on the wing flap. Due to the adjacent embodiment described above, a cost-effective production and a visually appealing appearance can be achieved.

According to a further advantageous feature of the invention, the section has a cutout, which overlaps the wing flap toward the building interior. The cutout forms, together with the section, in places a platform or console to which necessary functional elements can be attached. A processing of the frame for sufficient space of the functional elements can be omitted. On the enlarged surface can easily arrange the locking means.

A further embodiment provides that the section has the bore for forming the pivot hole and at the neck the locking bead and a stop is attached. The fact that the bore for pivotal mounting of the extension arm is already provided in the portion of the plate-shaped bearing element, the pivot bearing receives a stable position. In addition, the position advantageously contributes to requiring little space on the inside of the building so that the bearing element protrudes slightly above the wing overturn. At the same time the visual appearance of the fitting is favorably influenced.

An optimal and simple manufacture and assembly of the bearing element is achieved in that the rivet has a rivet head and starting from the rivet head, a first hole passes through a first bore on the portion of the bearing plate, a second paragraph passes through a bore of the damping element and a third paragraph with a Lock washer enters a rivet connection. The assignment of the damping element from the arranged on the bearing element rivet to the stay allows a particularly simple installation with an exact guidance of the damping element, which ensures an advantageous control of the bearing element. This gives the damping element secured in the axial and radial directions immovable position. An escape of the damping element is also avoided. During the transition of the extension arm from the closed position to the tilted position of the building window or door, the damping element is compressed, so that the resulting impulse by the weight and the opening movement of the wing significantly reduces the velocity of attack of the wing. Subsequently, the wing is controlled in a secure Ausstelllage both for the tilted position and for the parallel parked position. Due to the configuration described above, almost all other components of the bearing element remain unloaded.

Finally, a development of a fitting provides that the central axis of the bore of the bearing plate and the central axis of the bore of the extension arm for receiving the damping element in the closed position and in the tilted end position of the building window or door is almost congruent and spaced apart from tilted end position.

The different distances are generated with the effect of the damping element. Depending on the choice of material and the tolerance between the components of the razor, the distance may vary.

In the figures, a building window or door 1 is provided, consisting of a frame 2, with a provided in the frame 2, the fixed-field glazing 3 having fixed field and a wing 4. The substantially of the sash 5 with a glazing. 6 existing wing 4 is provided by means of a Parallelschiebekipp fitting on the frame 2 such that the wing 4 from his in the FIG. 1 shown closure position in which closes the window opening formed laterally of the fixed field in the frame 2, by moving perpendicular to the window and wing plane (raising movement) in a Ausstelllage after FIG. 3 and then by moving parallel to the window plane in an open position is movable, in which the wing 4 is seen from the inside of the building ago in front of the fixed-field glazing 3. Furthermore, the wing 4, for example, for airing from its closed position tilted, as shown in the FIG. 2 is shown.

The actuatable via an actuating handle 7 Parallelabstell fitting includes, inter alia, a carriage assembly which is provided in the region of the underside of the lower horizontal Holmes 8 of the sash 5 and consists essentially of two spaced carriages 9. Each carriage 9 has a carriage element 10 which is guided with carriage rollers in a lower, horizontal running or guide rail 11 at the lower horizontal portion 8 of the frame 2 and hinged to one end of a lower extension arm 12. The other end of each Ausstellarms 12 is pivotally connected to a bearing element 13, with which the respective carriage 9 is fixed to the spar 8. The two carriage elements 10 are connected to each other via a lower connecting rod 14, so that the two extension arms 12, the connecting rod 14, the bearing elements 13 and the joints at the ends of the extension arms 12 form a lower articulated parallelogram. About this is always guaranteed a parallel position of the lower portion of the wing 4 with the plane of the frame 2 in the wing movement perpendicular to the window plane.

At the upper horizontal spar 15 of the sash 5 after FIG. 4 are in turn spaced from each other and in each case in the vicinity of a local corner of the sash 5, two bearing elements 16 are fixed to the sash 5. The two bearing elements 16 have as a base body to a bearing plate 24, which in the illustrated embodiment according to FIGS. 5 to 6 each essentially of a section 27 and a leg 28 together form an elbow.
The cross-sectionally L-shaped bearing plate 24 leans due to its design FIG. 4 and FIG. 5 at the upper horizontal spar 15 and the wing flap 41 of the sash 5 at. The leg 27 is arranged on the voltage applied to the upper edge of the sash 5, the portion 28 with its free end 29, the upper edge of the spar in the direction of the upper horizontal spar 30 of the frame 2 angularly engages over and rests on the wing flap 41.

In the manufacturing process of the bearing plate 24, a cutout 26 is punched out before the bending process, ie, before the leg 27 and section 28 is formed. The cutout 26 is automatically bent together with the portion 28 during the bending operation at an angle of 90 °. The section 28 and the cutout 26 form part of an enlarged platform or console.
The cutout 26 also overlaps the wing flap 41, however, in the direction towards the inside of the upper horizontal spar 30 to the inside of the building. This results in at least partially an enlarged surface of the portion 28 on which the locking means 17, consisting of a locking bead 19 and a stop 31, are arranged. The bearing element 16 facing end of a stay arm 25 is disposed on the section 28.

Each bearing member 16 is secured using suitable fasteners, e.g. Screws on the leg 27 and / or attached to the upper edge of the sash 5 section 28 attached to the sash 5.

By the assignment of the extension arm 25 on a rivet 20 which is held in a mounted to the free end 29 of the bearing plate 24 bore 32, the cutout 26 projects beyond the wing flap 41 of the sash 5 only slightly.
The other end of the extension arm 25 is after FIG. 4 and FIG. 5 hinged to a pivot bearing 23, wherein -in FIG. 6 shown a pivot pin 40 engages in a slider, not shown.

Simplifies the assembly or disassembly of the wing 4 on the frame 2 in that the pivot pin 40 is releasably held in a hinge opening. The pivoting sliding bearing 23 is slidably received in the longitudinal direction over the slider in an upper guide rail 39. The guide rail 39 is attached to the upper horizontal spar 30 of the frame 2 on the side facing the building interior surface resting. In the illustrated embodiment, the guide rail 39 is formed by a C-profile, which is open at its underside of the building window or door 1 facing bottom.

In the tilted position and in the parallel parked position hinged to the pivot slide bearing 23 and to the bearing elements 16 Ausstellarme 25 form a Gelenkparallelogramm, which ensures a clearly secured detent position by a damping element 22.

With the sash 4 closed FIG. 1 and FIG. 7 the two upper Ausstellarme 25 are oriented parallel or nearly parallel to the longitudinal axis of the guide rail 39 and are located immediately below this guide rail 39. When tilted or flared wing 4, the two Ausstellarme 25 are as in FIG. 4 shown with their longitudinal extent each oriented obliquely to the longitudinal axis of the guide rail 39, ie the opening arms 25 close to the longitudinal axis of the guide rail 39 an angle smaller than 90 °.

In the illustrated embodiment, the effective length of the extension arms 25, i. the distance between the two hinges on each extension arm 25 is equal to the effective length of the extension arms 12, i. equal to the distance between the two joints on each stay 12.

In order to enable the secure Ausstelllage the Ausstellarme 25 and thus the building window or door 1 in the tilted position and in the parallel parked position of the wing 4, a locking means 17 is provided on the bearing element 16, which securely fixes the opening arms 25. For this purpose, a nose 18 is attached to the bearing-side end of the extension arm 25, which in the rest position after FIG. 9 the locking bead 19 engages behind and abuts against the stop 31, which limits the Ausstelllage.

To simplify the production of the locking bead 19 and the stopper 31, they are stamped out of the bearing plate 24 to the side of the stay arm 25 out. For secure recording of the damping element 22, the rivet 20 after FIG. 6 a rivet head 32 and a first shoulder, which are received in the bore 32 of the portion 28 of the bearing plate 24. A second paragraph 35 passes through a bore 32 of the damping element 22, wherein a third shoulder 36 with a locking washer 38 enters into a riveted connection. Thus, the damping element 22 is completely enclosed and can develop its effect targeted. During the transition of the stay arm 25 from the closed position to the tilted position of the building window or the door 1, the sash weight of the sash 4 is absorbed by the damping element 22 and acts as a stop damping. In particular, by unintentional movements of the wing 4, for example, as a result of improper handling or the wing 4 impinging gust of the wing 4 is indeed stopped, but it still comes to a heavy load on the bearing element 16 and the entire opening limit. To prevent this, the material of the damping element 22 is compressed in the radial direction and against the inner walls the arranged in the extension arm 25 bore 21 and pressed against the second shoulder 35 of the rivet 20, so that an increased braking effect. In the compressed position of the damping element 22, the central axis of the bore 32 and the central axis of the bore 21 of the type is spaced from each other, as can be the material of the damping element 22 compresses. At the same time, the scissor arm 25 is oriented against the resistance of the damping element 22 further in the inclined position, the nose 18 around the locking bead 19 around FIG. 8 in the latched end position of the wing 4 after FIG. 9 goes over and comes to the stop 31 to the plant.

The damping element 22 is preferably made of a rubber material. But it can also be made of an elastically deformable plastic. With the simple design, at the same time the elastic properties can be exploited. The remaining components of the bearing element 16 are preferably made of metal, for example made of steel. The extension arms 25 can be made of a strip material due to their straight outer contour.

In a manner not shown may also be provided with a closed wing 4 snap-locking device of this type, which then causes a moment in the closed position in the final phase.
