Sliding JCipp door or window

The invention relates to a sliding and tilting door or a tilt and slide window. In a known sliding door, the upper wing end is issued and the wing below postponed. It is considered a disadvantage here that the sighting in the area of the lower wing end is not possible or at least not sufficiently relieved and therefore unnecessarily stressed or worn out when moving the sash will·

609843/0329

The object of the invention is therefore to provide a tilt and slide door or a tilt and slide window to create, the seals of which when moving in the tilted position no or at least only very low loads are exposed.

To solve this problem, a tilt and slide door or a tilt and slide window is provided, which according to the invention is characterized by a lifting device for the wing. This lifting device causes at least one extensive relief of the seal also in the lower wing area, and thus one achieves in the desired Way to protect the seal at this point on the wing.

A preferred embodiment of the invention provides that a transverse push-off device which can be actuated by the lifting device or the wing lifting device is attached on the closure side of the sash and frame or the like. "Closure side ¹¹ " refers to the vertical spars of the sash and window frame or the like, which laterally delimit the passage opening when the sash is displaced

809849 / Q32Q

This Querabrückvorrichtung achieves a slight displacement of the wing in the opening sense, which sufficient to be able to tilt the sash afterwards and to release the seals on the longitudinal edges. Here it is particularly advantageous that the activity of the cross-pushing device is inevitably linked to the movement of the lifting device or the sash lifting movement is coupled. So if you move the wing in particular with the help of the lifting device lifts, the transverse deflection of the wing takes place at the same time without any special measures being taken requirement. It is readily possible, and in the exemplary embodiment also provided, that the transverse push-off device only comes into operation after the sash has been raised to a certain extent. The lateral shift when pushing crosswise is on the order of approximately 1 cm.

In a further development of the invention it is proposed that the transverse push-off device consist of a push-off wedge of the wing and a counter wedge of the frame or the like. The counter wedge is in the stroke movement range of the forcing wedge is located. For example, those running at 45 °

- 10 -

Slopes of the forcing wedge and the counter wedge are a matter of course directed so that when the sash is raised, the pushing-off movement in the opening direction of the sliding sash he follows. When the sash is lowered, these surfaces can already be in contact with one another or have a short distance between them. which is of course smaller than the lifting height of the Wing. In order to be able to cope with the stresses of pushing the cross-r, it is advisable to at least remove the counter wedge a highly abrasion-resistant material, especially plastic. On the other hand, this material must also have a have sufficient sliding properties.

The forcing wedge is particularly expediently on a push rod that can be driven by the lifting device attached. This makes it possible to select the lifting movement of the forcing wedge greater than that of the wing. An advantageous embodiment of the invention in this context is that the push rod at the same time Transmission member for the movement of an actuator to the lifting mechanism of the wing is. The actuator can, for example, be a crank handle known from lift and slide doors, the rotary movement of which is via a

Linkage is transferred to the lifting mechanism. Another embodiment of the invention provides that the Counter wedge also forms a buffer element for the wing. However, the mating wedge does not necessarily have to be be the only element that absorbs the impact when the sliding sash is closed. The mating wedge is preferably made made of a hard elastic material.

Another variant of the invention provides that the push rod has a corner deflection with at least one opening device for the wing is connected. The lifting device, the cross-pushing device and the opening device must be designed in such a way that they are triggered by one and the same push rod or elements coupled to it Movements are coordinated. In particular, it is provided that the lifting device is initially in operation occurs and at the same time or shortly thereafter the Querabrückvorrichtung becomes effective. When the lifting movement of the wing is at least largely carried out, the deployment device for the wing should come into action. To have to that is, appropriately dimensioned lost motion sections must be available.

909845/0329

A further development of the invention provides that the deployment device is designed as a deployment arm whose The wing-side end is rotatably connected to an upper thrust member and a guide slot in the area of this axis of rotation has, in which a pin attached to the wing engages, the pin when closed Slotted part assigned to the wing for slight lifting the upper end of the wing from the frame or the like. Slightly inclined relative to the plane of the wing. The slightly inclined one The slot part forms the already mentioned lost motion section, However, it is particularly advantageous that even when moving the extension arm in this area upper wing end is turned off by a small amount, because this causes the seal at the upper wing end during the The transverse stop of the sash is already relieved. A slot part then closes at the slot part with a slight inclination greater inclination, with the help of which the actual transverse division of the upper wing end is made. The slot accordingly has an overall angled, possibly also arcuate, shape.

& 09849/0323

In the case of a door or a window with a corner drive on the front upper sash corner in the sliding / closing direction it is proposed according to the invention that the corner drive has a rotatably mounted bell angle which, when the sash is lowered and closed, with a hook-like approach a strike plate od. Like. Engages behind the window frame. The bell angle translates into known way the movement of a vertical push rod to a horizontal one. To this end, his two are Angle legs each rotatably connected to a bracket, the free ends of which with the vertical or horizontal Push rod are coupled. When the raised wing is lowered, the bell angle rotates, for example counterclockwise. The hook-like approach makes this rotary movement with and engages behind the free hook end while the strike plate or the like of the window frame, so that both frames over the strike plate and the hook-like Approach to be locked together at this point. The strike plate or the like is more advantageous Way adjustable at least in the vertical direction.

Furthermore, in the case of a door or a window with a detachable locking device, in particular at the bottom

- 14 & 098A9 / 032Ö

2824208

According to the invention proposed wing end of the closing side, that the locking device consists of a spring-loaded locking lever of the sash and a strike plate or the like of the window frame or the like. The locking lever can be triggered by means of an actuating mechanism against the force of the loading spring. Similar to the one before The above-mentioned locking on the upper wing end also prevents the latching on the opposite lower wing end unwanted shifting, i.e. opening of the sash, This locking device is even with the sash tilted effective and thus forms a burglar protection. Moving the raised and tilted sash is so only possible if you move the locking lever against the resistance of its loading spring in the disengaging direction, in particular pivoted. The aforementioned actuation mechanism, which is based on the nature of the matter, is used for this purpose must be operated by hand. Expediently, the actuating mechanism is also designed to be self-resetting, so that the latching lever is in the latching division even when the sash is completely or partially displaced into the open position can return. If you use the locking lever with a

- 15 S098AS / 0329

When the sash is subsequently closed, it automatically engages with its strike plate again or the like. In order to avoid unauthorized action on the actuating mechanism, it can be locked train and / or directly provide a key as an actuator.

In the case of a sliding door or a sliding window, its sliding sash along a fixed field or opposite a second wing is displaceable, is according to the invention suggested that the upper cross member of the fixed field or second wing at its against the sliding sash facing surface has a first, open-edged receiving groove for a sealing strip and on the upper cross member of the lift-slide sash a second, against the frame or the like. Open-edged receiving groove for a sealing strip is attached. In the case of a tilt and slide sash, the first slot is inserted a sealing strip, the sealing lip or lips of which the gap between the fixed field and the Bridge the sliding sash and rest on it in the vertical position of the latter. The second receiving groove remains

- 16 909849/0329

thereby unused. With a non-tiltable, purely lift & slide sash the sealing strip is inserted into the second receiving groove, and its sealing lip is then lowered The sash is attached to an upper guide rail attached to the frame. Then stay with this second case the first groove is unused. On the other hand, the aforementioned training has the advantage that you can use the frame, can edit the frame of the sliding sash and the fixed field or a second sash all the same, independently whether the sliding sash is used either as a pure lift & slide sash or as a lift & slide & tilt sash will. In this way, larger series can be produced and the grand piano can later be made easy in this regard can be switched from one operating mode to the other.

A further development of the invention provides that on the side of the second receiving groove a third, open-edged groove on the lift and slide sash is attached, which runs parallel to the second receiving groove. This third receiving groove, which is expedient is larger in cross-section than the second, takes one with it in the case of a pure lift-slide sash

- 17 -

§09849 / 0328

the mentioned guide rail cooperating guide rail on. If, on the other hand, the sliding sash is also to be tiltable, the opening device is fastened in this third groove or display devices. The second receiving groove is located in a further embodiment of the invention between the first and the third groove.

Another variant of the invention provides that there is a fourth against the second and / or third on the frame Groove is open-edged fastening groove. Like the third groove, this can be used in two ways: In the case of the pure lift and slide sash, it takes up the fastening leg of the guide rail mentioned. With the lift & slide & tilt sash, the fourth fastening groove the frame-side end of the opening device or devices is supported. It goes without saying that the parts mentioned are dimensioned so that they each fit exactly into these grooves and they, as far as required to fill in.

Exemplary embodiments of the invention are shown in the drawing. Show it:

A lift-slide-tilt sash 2 is located in the frame 1 used, which is displaceable along a second wing 3 designed as a fixed field. The lift-slide-tilt sash is supported by preferably two carriages 4 on a running rail 5 of the frame 1. At the On the underside of the wing there is a lifting cam 6 in the area of each carriage, which by the upper limit of a Guide slot 7 is formed. The guide slot is located on one screwed onto the underside of the wing Fitting part 8. 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, for example, clockwise, this rotary movement is effected via a linkage transferred to the carriages 4, which are relative to the wing 2

- 20 809849/0329

move in the direction of arrow 12. The roller 9 then slides along the lifting cam 6 and causes the lifting of the Wing in the direction of arrow 13.

The rotary movement of the hand crank is transmitted to the push rod 14 in a suitable and known manner. When lifting of the wing 2 it moves upwards. It has a push-off wedge in the area of the lower left wing corner 15, which forms a transverse push-off device 17 with a counter wedge 16 of the window frame 1. In the exemplary embodiment the forcing wedge 15 has a small distance from the counter wedge 16 when the wing 2 is lowered, although this is not necessarily is required. As soon as the inclined surface 18 of the forcing wedge 15 on the inclined surface 19 of the counter wedge 16 is applied, the lifting of the wing 2 in the direction of arrow 13 simultaneously causes a push-off, i.e. displacement in the direction of the arrow 20. As a result, the wing comes off both the lower seal and during this lifting movement the two side seals. As will be explained later, you can achieve this with the help of an opening device at the same time the seal at the upper end of the wing came free.

- 21 -

909849/0329

The two inclined surfaces preferably run at 45 ° and their direction is chosen so that from the lifting movement of the wing 2 in the direction of arrow 13, the transverse displacement in the direction of arrow 20 results. The push-off wedge 15 is made Made of a highly abrasion-resistant material with good sliding properties, especially plastic. It also forms a buffer on which the left vertical spar of the wing strikes when closing.

The aforementioned push rod 14 or a further push rod coupled to it is via a corner deflection 21 with at least one, but preferably several, side by side at the upper end of the lift-slide-tilt sash 2 provided, preferably identically designed and coupled to one another raising devices 22 for the wing 2 tied together. Each deployment device has a deployment arm 23, the end of which on the blind frame side is a slider 25 carries, which is displaceable in a guide rail 25 of the window frame 1. The slider is rotatable on the fixed with the frame-side end of the extension arm 23 connected bolt 26 is mounted. One attached to the top of the wing Fitting part 27 carries an upward-facing,

- 22 -

§09849 / 0329

Guide bolt or pin 28 acting in the manner of a sliding block. This engages in a guide slot 29 of the extension arm 23. One now moves an upper push rod with the help of the push rod 14 and the corner drive 21 30 in the direction of arrow 31, on which the pivot axis 32 of the extension arm 2 3 is attached, results in this displacement movement is a pivoting movement of the extension arm 23 into that shown in FIG. 8 with dashed lines location shown. Because the extension arm is also rotatably mounted on the frame, the push rod moves 30 the pivoting of the upper end of the wing relative to the frame 1, i.e. the tilting of the lift-slide-tilt plane.

As shown, for example, in FIG. 8, the guide slot has an angular shape. Its a shi part 33, in the right end of which the pin 28 is located when the wing is closed, runs opposite the wing plane slightly inclined. The inclined course is chosen so that a relative displacement of the pin 28 in the slot part 33 in the direction of arrow 34 results in a slight tilting movement of the wing 2. While the

- 23 §00849 / 0320

a slot part 33 opposite the wing-fixed pin is used to raise the wing with the aid of the lifting device 6, 9 and the transverse setting by means of the transverse push-off device 17. The hand crank is rotated by 90 °, for example. During the second 90 ° rotation of the With the hand crank, the wing is only raised insignificantly, but the actual tilting movement of the takes place now Wing, because now the strongly inclined slot part 35 of the guide slot 29 along the pin 28 is moved. Whether or not there is also a transverse push-off depends on the design of the transverse 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 acting in the return direction of the opening device, in particular bow spring. In this way you turn off the game in the opening device, so that the tilted Wing gets good stability.

The up and down movement of the push rod 14 is transmitted via a bracket 38 to a bell angle 39 and with it

- 24 §09849 / 0313

Abandoned with the help of a second tab 40 on the push rod 30. The bell angle 39 is with the help of the axis 41 rotatably mounted on the wing 2. It has a hook-like extension 41 which, when the sash 2 is closed, has a strike plate 42 of the frame 1 engages behind and thus causes a lock on this upper wing corner. That Striking plate 42 is adjustable at least in the vertical direction.

A similar locking device 43 is also on the lower, wing corner on the closing side provided. It essentially consists of a latching lever 44 which, by means of a Compression spring 45 spring-loaded in the direction of arrow 46 and fastened about an axis 47 to one on the underside of the wing 2 Fitting part 48 is rotatable. Due to the force of the loading spring 45, the latching lever normally takes the in Fig. 3 is a position drawn with solid lines. He engages behind a strike plate 49 or the like of the window frame 1. If you disregard the aforementioned latching on the closing-side upper wing corner, the can The wing 2 can only be moved in the direction of the arrow 20 when the latching of the lever 44 with the strike plate 49

- 25 809840/0320

is resolved. This is achieved with the help of a special operating mechanism.

The actuating mechanism for the latching lever 44 has a push rod 50, the lower, cranked end of which (Fig. 3) rests on the upwardly facing edge of the locking lever 44, in particular in one located there Notch engages. The upper end of this push rod 50 is, as shown in FIGS. 4 and 5, with one around an axis rotatable, double-armed lever 52 coupled. This engages, for example, with its hook-like end in an opening the push rod 50 a. The right in Fig. 4 lever arm is connected to a helical tension spring 5 3, which him loaded 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 actuator 56. If you turn the latter in the direction of arrow 57, so that causes a lifting of the intermediate piece 50, and due to the reversal of movement with the help of the double-armed Lever 52 a downward movement of the push rod 50 in the direction of arrow 58. This in turn has a pivoting of the

- 26 -

909849/0319

locking lever 44 of the locking device 43 against the arrow 46 result, as a result of which the latching lever comes free from the strike plate 49 and releases the wing 2 at this point. That Actuating member 56 can belong to a lock cylinder 59, for example. In this case, the latching can only be solved if you have the associated key. You can of course use a simple one instead Provide turning handle. If you move the upper end of the intermediate piece 55 with the aid of the element 60 in the direction of the arrow 61 moves, 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 twist grip or key.

The second, designed as a fixed field wing 3 has on its upper transverse spar 62, namely on its against the Lift-slide-tilt sash facing surface 63 a first, Open-edged receiving groove 64 for a sealing strip 65. In addition, this lift-slide-tilt sash 2 is on the upper cross member 66 a second, open-edged receiving groove 6 7 for a sealing strip 68 is provided towards the frame 1. Unless the Wing 2 is used as a lift-slide-tilt sash, a sealing strip is merely placed in the first receiving groove 64 65, the sealing lips of which are then attached to the associated

- 27 -

909849/0329

surface 69 to be pressed. However, if the wing 70 is to be used as a purely lifting-sliding wing 70, then one sets only in the second receiving groove 67 a sealing strip 68, which is then in the lowered wing position rests with its sealing lip on the associated leg 71 of a guide rail 72.

With its free end 71, the guide rail 72 engages in the gap when the lifting / sliding sash 70 is raised a second guide rail 73 which is inserted into a third groove 74 which is open at the top towards the frame 1 of the lift and slide sash 70 is embedded. This third groove 74 accordingly runs parallel to the second receiving groove 67, which is in Fig. 10 to the left of her. When the sash is raised, the sealing lip of the sealing strip 78 lifts off Leg 71 of the guide rail 72 from. In an analogous manner, the sealing lips of the sealing strip 65 come from the lift-slide-tilt sash 2 free when it is tilted in the direction of arrow 75.

The baseboard 76 of the guide rail 72 is in a fourth, open-edged fastening towards the wing 2 or 70.

- 28 509849/0320

Stigungsnut 77 of the frame 1 held. In the case of a lift & slide & tilt sash, the end of the opening device on the blind frame side is in the fourth fastening groove 77 22 supported. The flight-side end of the opening device or devices 22 is held in the third groove 74 instead of the second guide rail 73. The four grooves 64, 67, 74 and 77 allow you to edit the three frames in the same way, regardless of whether they are Lift & slide tilt sash or just around a lift & slide sash acts. This greatly facilitates the window manufacturer's work and enables larger series.

So that the locking lever 44 does not hinder the transverse separation can, its free hook end when the wing is closed from the strike plate 49 or the like. A lateral distance of about corresponds to the extent of the transverse adjustment.
