Description

The invention relates to a sliding-tilt door or window with a wing sealed against the frame, which is provided to relieve the lower and upper seal with a lifting device acting on a carriage and by means of at least one upper side, movable in a guide rail of the frame Display device is tiltable. Such a window or door has become known, for example, from DE-A-2 006 133. When this sash is lifted, 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 that can be actuated by the lifting device or the wing lifting movement on the closure side of the sash and frame (DE-C-1 559 786), but a gasket that is arranged laterally between the sash and frame remains under tension so that At this point there is unavoidable seal wear.

The object of the invention is therefore to develop a 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.

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. In this door or window, a transverse movement in the direction of displacement is not only coupled with the lifting movement, but at the same time there is also a slight removal of the upper wing part from the laterally arranged, upper seals, so that all in the desired manner when the lifting device is actuated 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.

In a further development of the invention it is proposed that the push-off device or the like consist of a push-off part of the wing and a counter wedge of the frame. there is, the counter wedge is in the stroke movement range of the push-off wedge. The bevels of the push-off part and the counter wedge, for example at 45 °, are of course directed so that when the wing is lifted, the push-off movement takes place in the opening sense of the sliding wing. When the sash is lowered, these surfaces can already be in contact with one another or have a small distance, which is of course less than the lifting height of the sash. In order to be able to cope with the stresses during pressing, it is advisable to at least manufacture the counter wedge from a highly abrasion-resistant material, in particular plastic. On the other hand, this material must also have sufficient sliding properties.

The push-off part is fastened in a particularly expedient manner to a push rod which can be driven by the lifting device. This makes it possible to choose a greater stroke movement of the push-off part than that of the wing. An advantageous embodiment of the invention in this context is that the push rod is at the same time a transmission element for the movement from an actuating element to the lifting mechanism of the wing. The actuator can be, for example, a hand crank known from lifting and sliding doors, the rotary movement of which is transmitted to the lifting mechanism via a linkage. A further embodiment of the invention provides that the counter wedge also forms a buffer element for the wing. However, the mating wedge need not necessarily be the only element that absorbs the impact when the sliding sash is closed. The counter wedge is preferably made of a hard elastic material.

Another variant of the invention provides that the push rod is connected via a corner deflection to at least one opening device for the wing. The lifting device, the push-off device and the opening device must be designed such that their movements caused by one and the same push rod or elements coupled therewith are coordinated with one another. In particular, it is provided that the lifting device starts operating and the push-off device takes effect simultaneously or shortly thereafter. If the lifting movement of the wing is at least largely carried out, the opening device for the wing should come into operation. Correspondingly dimensioned backlash distances must therefore be available.

A further development of the invention provides that the raising device is designed as a raising arm, the wing-side end of which is rotatably connected to an upper thrust member and a guide in the region of this axis of rotation tion slot in which a pin attached to the wing engages, the slot associated with the pin when the wing is closed for slightly lifting the upper wing end from the frame or the like. runs slightly inclined to the wing plane. The slightly inclined slit part forms the lost motion section already mentioned, but it is particularly advantageous that the upper wing end is turned off by a small amount even when the extension arm is moved in this area, because this already seals the upper wing end while the wing is in the transverse position is relieved. A slot part with a greater inclination then adjoins the slot part with a slight inclination, with the aid of which the actual transverse adjustment of the upper wing end is carried out. Accordingly, the slot has an overall angular, possibly also arcuate shape.

In the case of a door or a window with a corner deflection on the upper wing corner at the front in the sliding-closing direction, it is proposed according to the invention that the corner deflection has a rotatably mounted bell angle which, when the wing is lowered and closed, has a striking plate or the like with a hook-like attachment. reaches behind the frame. The bell angle transfers the movement of a vertical push rod to a horizontal one in a known manner. For this purpose, its two angle legs are each rotatably connected to a tab, the free ends of which are coupled to the vertical or horizontal push rod. When the raised wing is lowered, the bell angle rotates counterclockwise, for example. The hook-like approach makes this rotary movement and the free hook end engages behind the striking plate or the like. of the frame, so that both frames are locked together at this point via the striking plate and the hook-like attachment. The striking plate or the like. is advantageously adjustable at least in the vertical direction.

Furthermore, according to the invention, in the case of a door or a window with a releasable latching device, in particular at the lower wing end of the closing side, it is proposed that the latching device consist of a spring-loaded latching lever of the wing and a striking plate or the like. of the frame or the like. there, the locking lever can be triggered by an actuating mechanism against the force of the loading spring. Similar to the lock on the upper flight end discussed above, the latching on the opposite lower end of the wing also prevents undesired displacement, i.e. Opening the wing. This locking device is effective even when the sash is tilted and therefore forms a burglar alarm. A displacement 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. The above-mentioned actuation mechanism serves this purpose, 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 you provide the locking lever with a run-on slope, it automatically locks again with its striking plate or the like when the leaf is subsequently closed. In order to avoid unauthorized interference with the actuating mechanism, it can be designed to be lockable and / or a key can be provided directly as an actuating element.

In a lift-slide-tilt door or a lift-slide-tilt window, the sliding sash of which can be moved along a fixed field or with respect to a second sash, it is proposed according to the invention that the upper cross member of the fixed field or second sash on its opposite the sliding wing facing surface has a first, open edge receiving groove for a sealing strip. In the case of a sliding and tilting wing, a sealing strip is inserted into the first receiving groove, the sealing lip or lips of which bridge the gap between the fixed field and the sliding wing and rest against it in the vertical position of the latter.

A further development of the invention provides that a third, open-edged groove is attached to the side of a second receiving groove on the lifting and sliding sash and runs parallel to the second receiving groove. This third receiving groove, which is expediently larger in cross section than the second one, is taken out by the opening device. Display devices on. In a further embodiment of the invention, the second receiving groove is located between the first and the third groove.

Another variant of the invention provides that a fourth fastening groove, which is open towards the edge against the second and / or third groove, is located on the frame. With the lift-slide-tilt sash, the end of the opening device or devices on the frame side is mounted in the fourth fastening groove. It goes without saying that the parts mentioned are dimensioned so that they fit exactly into these grooves and fill them out as necessary.

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 you turn the hand crank 11 (FIG. 1) clockwise, for example, this rotary movement is transmitted via a linkage to the carriages 4, which move 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 bears against the inclined surface 19 of the counter-wedge 16, the lifting of the wing 2 in the direction of 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 below 45 °, and their direction is selected such 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 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 of the pivot axis 32, runs in the tilting end position on one leg 36 of a spring 37, in particular a bow spring, which acts in the return direction of the opening device. 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 with the help of a second La see 40 on the push rod 30 abandoned. The bell bracket 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 sash 2 is closed, engages behind a striking plate 42 of the frame 1 and thus interlocks this upper sash 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 consists essentially of a locking lever 44 which is spring-loaded in the direction of arrow 46 by means of a compression spring 45 and can be rotated about an axis 47 on a fitting part 48 fastened to the underside of the wing 2. Due to the force of the load spring 45, the latch lever normally assumes the position drawn in solid lines in FIG. 3. He engages behind a striking plate 49 or the like. of the frame 1. If one disregards the above-mentioned latching on the closing upper wing corner, the wing 2 can only be moved in the direction of arrow 20 if the latching of the lever 44 with the striking 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 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-edge receiving groove 64 for a sealing strip 65 on its upper cross member 62, specifically on its surface 63 pointing against 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 lies in the lowered wing position with its sealing lip on the associated leg of a guide rail with its sealing lip.

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 locking lever 44 can not hinder the transverse parking, its free hook end has the closing plate 49 or the like when the sash is closed. a lateral distance that corresponds approximately to the size of the transverse parking.
