Description

The invention relates to a (e) sliding-tilt door or window with a wing sealed against the frame, which is provided to relieve the lower and upper seal with a wing lifting device acting on a carriage and by means of at least one top, in a guide rail of the frame displaceable opening device is tiltable, with a releasable locking device is provided on the lower wing end on the closing side. Such a window or such a door has become known, for example, from DE-A 2006133. When lifting this sash, the upper and lower seals between the sash and frame are released, but the side seals between the frame and sash are not released during the sash lifting movement and are therefore subject to considerable wear and tear. These seals are only relieved by tilting.

Furthermore, it is known to provide a push-off device which can be actuated by the lifting device or the wing lifting movement on the closure side on the sash and frame (DE-C 1 559 786), but a gasket which is arranged laterally between the sash and frame remains under tension so that on there is unavoidable seal wear at this point.

In a tilt and slide sash according to DE-A 2603240 it is provided that to relieve the seal provided on the end face between the sash and the frame, a push-off device which can be actuated by the locking mechanism and is effective in the direction of displacement of the sash is attached, and at the same time as the lifting movement of the push-off cam on the sash, there is a slight pivoting movement of the opening device coupled to the locking mechanism to relieve the upper seal arranged laterally between sash and frame.

The sliding leaf fitting known from DE-U 1 965136 has a locking device with a spring-loaded, leaf-side locking lever which, in the installed position, cooperates with a striking plate on the frame. The locking lever to be arranged at the lower wing end can be triggered by an actuating mechanism against the force of a load spring. The actuating mechanism has a push rod which can be moved back and forth by means of a rotary member.

DE-A 631 063 discloses a closure for sliding doors with a releasable latching device at the lower wing end, which consists of a spring-loaded latching lever of the wing and a striking plate or the like on the frame, the latching lever being releasable by means of an actuating mechanism against the force of the load spring .

The object of the invention is to develop a (e) sliding-tilt door or window of the type mentioned in such a way that even when using a seal arranged laterally between the sash and frame, all seals are relieved at the start of lifting, and that Locking is effective even with the wing raised and tilted.

To achieve this object, it is proposed according to the invention that the slide-tilt door or the slide-tilt window is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim. With this door or window, not only is a transverse movement coupled with the lifting movement in the direction of displacement, but at the same time there is also a slight removal of the upper wing part from the laterally arranged upper seals, so that in the desired manner, when the lifting device is actuated, all of them at the same time Seals are relieved. This avoids wear and tear when opening and, if necessary, later moving, and instead achieves a long service life for all seals.

It is readily possible, and in the exemplary embodiment also provided, to design and arrange the parts which are relevant for the movements mentioned in such a way that the push-off device only comes into action after the wing has been raised a certain amount. The lateral shift when pressing is in the order of magnitude of approximately 1 cm. The latch at the lower wing end prevents unwanted shifting, i.e. Opening the wing. This locking device is effective even when the sash is tilted and therefore forms a burglar alarm. A shifting of the raised and tilted wing is only possible if you move the locking lever against the resistance of its loading spring in the disengaging direction, in particular pivoted. This is the purpose of the actuation mechanism, which has to be actuated manually by nature. The actuating mechanism is also expediently designed to be self-resetting, so that the latching lever can return to the latching position even when the wing is completely or partially displaced into the open position. If the locking lever is provided with a bevel, it automatically locks again with its striking plate or the like when the leaf is subsequently closed.To prevent unauthorized interference with the actuating mechanism, it can be designed to be lockable and / or a key can be provided as an actuating element .

In the frame 1, a lift-slide-tilt sash 2 is inserted, which is displaceable along a second sash 3 designed as a fixed field. The lift-slide-tilt sash is supported on a slide rail 5 of the frame 1, preferably via two carriages 4. A lifting cam 6, which is formed by the upper boundary of a guide slot 7, is located on the underside of the wing in the region of each carriage. The guide slot is located on a fitting part 8 screwed to the underside of the wing. It is penetrated by a roller 9 which is held in two parallel cheeks 10 of the carriage, which are located on both sides of the guide slot 7. If the hand crank 11 (FIG. 1) is rotated clockwise, for example, this rotary movement is transmitted to the carriage 4 via a linkage, which moves relative to the wing 2 in the direction of the arrow 12. The roller 9 then slides along the lifting cam 6 and causes the wing to be raised in the direction of the arrow 13.

The rotary movement of the hand crank is transmitted to the push rod 14 in a suitable and known manner. When wing 2 is lifted, it moves upwards. It bears a push-off wedge 15 in the area of the lower left wing corner, which forms a push-off device 17 with a counter-wedge 16 of the frame 1. In the exemplary embodiment, the push-off wedge 15 is at a small distance from the counter-wedge 16 when the sash 2 is lowered, although this is not absolutely necessary. As soon as the inclined surface 18 of the push-off wedge 15 abuts against the inclined surface 19 of the counter-wedge 16, the lifting of the wing 2 in the direction of the arrow 13 simultaneously causes a push-off, i.e. Moving in the direction of arrow 20. As a result, during this lifting movement, the wing comes free from both the lower seal and the two side seals. As will be explained later, the opening of the seal at the upper wing end is also achieved with the aid of an opening device.

The two inclined surfaces preferably run at 45 °, and their direction is selected so that the transverse movement in the direction of arrow 20 results from the lifting movement of the wing 2 in the direction of arrow 13. The push-off part 15 consists of a highly abrasion-resistant material with good sliding properties, in particular plastic. In addition, it forms a buffer on which the left vertical spar of the wing hits when closing.

The aforementioned push rod 14 or a further push rod coupled to it is connected via a corner deflection 21 with at least one, but preferably a plurality of, preferably identically designed and coupled to one another, for the wing 2, at least one, but preferably several, provided next to one another at the upper end of the lift-slide-tilt sash 2 connected. Each raising device has a raising arm 23, the end of which, like a frame, carries a slide 25 which is displaceable in a guide rail 25 of the frame 1. The slider is rotatably mounted on the bolt 26 which is fixedly connected to the end of the opening arm 23 on the frame side. A fitting part 27 fastened to the upper wing end carries an upward-pointing guide pin or pin 28, which acts in the manner of a sliding block. This engages in a guide slot 29 of the extension arm 23. If you now use the push rod 14 and the corner guide 21 to move an upper push rod 30 in the direction of arrow 31 to which the pivot axis 32 of the extension arm 23 is fastened, this displacement movement results in a pivoting movement of the extension arm 23 into the broken lines in FIG. 8 shown location. Because the extension arm is also rotatably mounted on the frame, the displacement of the push rod 30 causes the upper wing end to pivot relative to the frame 1, i.e. the tilting of the lift-slide-tilt sash.

As shown, for example, in FIG. 8, the guide slot has an angular shape. Its one slot part 33, in the right end of which the pin 28 is when the wing is closed, is slightly inclined with respect to the wing plane. The inclined course is selected such that a relative displacement of the pin 28 in the slot part 33 in the direction of the arrow 34 results in a slight tilting movement of the wing 2. During the displacement of the one slot part 33 with respect to the wing-fixed pin 28, the wing is lifted with the aid of the lifting device 6, 9 and the transverse shutdown by means of the transverse push-off device 17. The hand crank is rotated, for example, by 90 °. During the second 90 ° rotation of the hand crank, the wing is raised only slightly, but the actual tilting movement of the wing now takes place because now the slanting slot part 35 of the guide slot 29 is displaced along the pin 28. Whether a push-off also takes place depends on the design of the push-off device in detail.

The wing-side end of the opening device, in particular a downward extension approximation of the pivot axis 32, runs in the tilt end position on one leg 36 of a spring 37 acting in the return direction of the stiffening device, in particular a bow spring. In this way, the game in the display device is switched off, so that the tilted wing is given good stability.

The up and down movement of the push rod 14 is transmitted via a bracket 38 to a bell bracket 39 and is applied to the push rod 30 with the aid of a second bracket 40. The bell angle 39 is rotatably mounted on the wing 2 with the aid of the axis 41. It has a hook-like extension 41 which, when the wing 2 is closed, engages behind a striking plate 42 of the frame 1 and thus causes a locking at this upper wing corner. The striking plate 42 is adjustable at least in the vertical direction.

A similar latching device 43 is also provided on the lower wing corner on the closing side. It essentially consists of a locking lever 44 which is spring-loaded in the direction of arrow 46 by means of a compression spring 45 and is rotatable about an axis 47 on a fitting part 48 fastened to the underside of the wing 2. Due to the force of the actuating spring 45, the latch lever normally assumes the position drawn with solid lines in FIG. He engages behind a striking plate 49 or the like of the frame 1. If one disregards the above-mentioned latching on the upper wing corner on the closing side, the wing 2 can only be shifted in the direction of arrow 20 if the latching of the lever 44 with the Strike plate 49 is released. This is achieved with the help of a special actuation mechanism.

The actuating mechanism for the locking lever 44 has a push rod 50, the lower, bent end (FIG. 3) of which rests on the upward-facing edge of the locking lever 44, in particular engages in a notch located there. The upper end of this push rod 50, as shown in FIGS. 4 and 5, is coupled to a double-armed lever 52 which can be rotated about an axis 51. This engages, for example, with its hook-like end in an opening in the push rod 50. The right lever arm in FIG. 4 is connected to a tension coil spring 53 which loads it clockwise. In addition, a tab-like intermediate piece 55 engages on this lever arm 54, which is coupled or can be coupled to a rotatable actuating member 56. If the latter is rotated in the direction of arrow 57, this causes the intermediate piece 50 to be raised and, due to the reversal of movement with the aid of the double-armed lever 52, the push rod 50 moves downward in the direction of the arrow 58. This in turn causes the latching lever 44 of the latching device 43 to pivot contrary to arrow 46, whereby the locking lever is released from the striking plate 49 and releases the wing 2 at this point. The actuating member 56 can, for example, belong to a locking cylinder 59. In this case, the locking can only be released if you have the corresponding key. Instead, you can of course also provide a simple twist grip. If the upper end of the intermediate piece 55 is moved in the direction of arrow 61 with the aid of the element 60, the actuating member 56, which is designed as a cam, can no longer act on the intermediate piece 55. On the other hand, a lock can then be operated using the rotary handle or key.

The second wing 3, which is designed as a fixed field, has a first, open-edged receiving groove 64 for a sealing strip 65 on its upper cross member 62, specifically on its surface 63 pointing towards the lift-slide-tilt-wing. Sliding-tilting wing 2, a second receiving groove 67, which is open towards the edge of the frame 1, is provided for a sealing strip 68. If the wing 2 is used as a lift-slide-tilt wing, only a sealing strip 65 is inserted into the first receiving groove 64, the sealing lips of which are then pressed onto the assigned wing surface 69. However, if the wing 70 is to be used as a pure lifting-sliding wing 70, a sealing strip is used exclusively in the second receiving groove 67, which then rests with its sealing lip on the associated leg of a guide rail in the lowered wing position.

The sealing lips of the sealing strip 65 are released from the lift-slide-tilt sash 2 when it is tilted in the direction of arrow 75.

The end of the opening device 22 on the frame side is supported in a fourth fastening groove 77. The wing-side end of the opening device or devices 22 is held in the third groove 74. The four grooves 64, 67, 74 and 77 enable the three frames to be machined in the same way, regardless of whether it is a lift-slide-tilt sash or just a lift-slide sash. This greatly facilitates the window builder's work and enables larger pages.

So that the latching lever 44 cannot hinder the transverse adjustment, its free hook end has a lateral distance from the striking plate 49 or the like when the sash is closed. This has a lateral distance which corresponds approximately to the dimension of the transverse adjustment.
