Description

The present invention relates to a sealing device for a sliding window, a sliding door or the like., Which has a movable in a frame along a direction of displacement between an open and a closed position in its plane wings. The invention further relates to a sliding window, a sliding door or the like. with such a sealing device.

Sliding wings are usually performed on their lateral sides in bearing rails of the frame. At least when closed, the wing should be sealed against the frame; if this is still relatively easy to achieve on its two end faces, which usually come to rest on the frame or a neighboring wing, the displacement movement between wing and frame in the region of the two stored lateral sides of the wing leads to considerable difficulties in sealing.

To seal the lateral sides of a sliding wing, it is from the scriptures FR 2 148 943 B and US 2009/0038228 A1 known to put the wing by means of a lever mechanism when closing transversely to its direction of displacement and transversely to the wing plane and to press against mounted in the frame or on the wing seals. Especially for large, heavy wings, especially those in pitched roofs, but for a shift very high effort, acting on the entire wing massive lever mechanism and bearing rails with equally massive additional bearings for the transverse displacement are required.

The font JP 62 113 286 U describes a similar lever mechanism that can press a sealing strip against the frame transverse to the direction of displacement and transversely to the plane of the wing. The contact pressure of the sealing strip acts not only against the wing itself, but indirectly loaded in the closed state also permanently its rail mounting.

The invention sets itself the goal of a sealing device for a sliding window, a sliding door or the like. to create, which is simple in construction, even with large wings, a comfortable handling allowed while sealing the wing in the region of its lateral sides without burdening its storage safely.

This object is achieved with a sealing device of the aforementioned type, which is characterized according to a first aspect of the invention by
a frame part which lies next to a lateral side of the wing running in the direction of displacement,
a pressure bar, which is movably mounted on the frame part and facing said lateral side, and
a coupling member which is actuated by the wing when it reaches its closed position and presses the pressure bar approximately parallel to the wing plane against the said lateral side or an attachable to the wing profile seal during its operation.

With the help of the sealing device according to the invention a safe, selbststerrichtende sealing effect is achieved when closing the wing without high component costs. A force component transverse to the wing plane and thus a load on the bearing of the wing or even a displacement of the wing transversely to its direction of displacement with a hand lever mechanism and the associated expenditure of force omitted entirely. The wing is mounted linearly displaceable, so it is easy to use and easy to handle; also transverse bearing on the wing or in the frame accounts.

It when the pressure bar is mounted on the frame part obliquely to the direction of displacement of the wing movable and the coupling member is a trained on the pressure bar stop for a driver of the wing is particularly advantageous. As a result, the pressure bar is automatically pressed simultaneously with the closing of the wing when it reaches its closed position. The oblique pressing and lifting movement of the pressure bar when closing or opening minimizes the friction between pressure bar and wing or profile seal, which protects the material and increases the life of the sealing device.

In order to achieve a particularly simple structure, preferably the stop is located at one end of the pressure bar and the driver is formed by an edge portion of the end face of the wing.

It is particularly favorable if, for the movable mounting of the pressure strip on the frame part of one of the two elements pressure bar and frame part at least one link and the other element has a sliding element engaging therein. As a result, any movement paths of the pressure bar relative to the wing can be achieved. So this could initially be done steeper against the lateral side or the profile seal when closing the wing and pressing the coupling member in order to experience this at a shallower angle safe and secure fit with high contact pressure.

Alternatively, the coupling member can be a lever mechanism mounted on the frame part and operable by the wing when it reaches its closed position and acting on the pressure bar. With such a lever mechanism, any translation of the pressing force can be achieved, even with such a mechanism a Ein- and Nachstellbarkeit to self-adjustment can be made possible. The movement of the pressure bar before and during its pressing against the lateral side or the profile seal can be designed arbitrarily depending on the bearing of the pressure bar and lever kinematics - also normal to the displacement direction in the wing plane.

In order to adjust the sealing device in a simple manner and sensitive, preferably the frame part is at least two parts with a first, the pressure bar overlapping support member and a second, mounted on the rest of the frame mounting part, wherein the support member is adjustably fixed to the mounting part, u.zw , preferably by means of elongated holes in the direction of displacement for the passage of fastening bolts. This causes a slight adjustment of the support member on the mounting part also a small change in the position of the pressure bar with respect to the coupling member and the driver and thus its effect on the pressure bar. In addition to the basic setting of the sealing device as well as their adjustment can be done in a simple and accurate manner, for example, when the sealing effect decreases as a result of aging or wear phenomena.

According to a preferred embodiment of the invention, the pressure bar has a normal to the wing plane, parallel to the direction of displacement first leg, with which it can be pressed against the lateral side or the profile seal. This ensures a secure fit of the pressure bar directly on the wing or the profile seal. Since the sealing effect is spread over a wider area, it can be high even at low pressure.

It is particularly preferred if the profile seal has a lip projecting from the plane of the wing, and the pressure strip has a second leg which is normal to the plane of the wing and parallel to the direction of displacement, with which it can be pressed against the lip. Thus, the pressing force of the pressure bar acts directly on the lip of the profile seal, and the wing is thus largely relieved. Such a lip can protrude especially on the outside of the wing, whereby the sealing effect is already there.

It is particularly advantageous if the frame part has a lip hat-like and play with overlapping stop bar, against which the lip comes when pressing the pressure bar to the plant. This reduces the mechanical stress on the lip by the pressure bar and decouples their pressing force almost entirely from the wing, which at the same time can achieve a very high sealing effect and a simplified because of the lower torsional load of the sealing lip construction and increased life of the profile seal.

If the sealing effect is to be further increased, then it is particularly advantageous if the pressure bar has a cross section has approximately Z-shaped profile, wherein the two legs of the Z form said first and second legs and the web connecting the legs of the Z is used for storage on the frame part. This leads to a double seal with an intermediate outflow channel for any penetrating residual or condensation water, in particular if, as preferred, the profile seal also has an approximately Z-shaped cross section, wherein the web of the Z on the wing and the one leg of the Z at its Lateralseite is attachable and the other leg of the Z forms the lip.

In order to facilitate a stable mounting of the wing and the inclusion of the components of the sealing device, it is advantageous if the frame part is a U-profile, within the opening of the wing is storable. Particularly preferably, the U-profile has a compartment for receiving a spindle drive for the displacement of the wing. Thus, if desired or required for weight reasons, the wing can not only be moved directly by hand, but there is the possibility of a mechanical drive, which can be operated manually or with a motor.

Furthermore, it is advantageous if the frame part has at least one brush seal which can be brought into contact with the outside of the wing. Such helps, in addition to their additional sealing effect, in particular for the profile seal harmful weather influences such as hail, snow, UV radiation, etc. to keep away from this, which positively affects the life of the sealing device.

In a second aspect, the invention provides a sliding window, a sliding door or the like, which has at least one in a frame along a direction of displacement between an open and a closed position in its plane sliding wings and a sealing device of the type presented here on each lateral side of the wing. With regard to the advantages of this arrangement, reference is made to the above comments on the sealing device.

The invention will be explained in more detail with reference to an embodiment shown in the accompanying drawings. In the drawings show:

• Fig. 1 a particularly suitable for installation in a roof surface sliding window according to the invention in a perspective view from above;

In Fig. 1 is a sliding window 1 with a circumferential, possibly correspondingly divided frame 2, a fixed therein fixed wing 3 and two slidably mounted therein wings 4, 4 'shown. The illustrated sliding window 1 is particularly suitable for installation in a sloping roof. The in Fig. 1 4 shown in an open position is as well as the wing 4 'in its plane along a displacement direction 5 slidably. The wings 4, 4 'are guided in each case on its two lateral sides 6 in the frame 2 slidably. In the following, reference will only be made to the wing 4; what has been said about the wing 4 applies in the same way to any other sliding wing of the sliding window 1, such as the wing 4 '.

At its front and rear end faces 7, 7 'of the wing 4 is sealed in its closed position in a conventional manner to the frame 2 and the adjacent wing 4' towards the weather on its outer side 8. In order to ensure the tightness of the wing 4 at its two lateral sides 6, there is provided in each case a sealing device, which will now be described in detail.

According to the Fig. 2 and 3 the sealing device comprises at least a part of the frame 2 next to the lateral side 6 of the wing 4, hereinafter referred to as the frame part 10. The frame part 10 supports a movable pressure bar 11 (see also Fig. 4 ). For this purpose, the frame part 10 has a support member 12, which by means of a sliding member 13, the pressure bar 11 and in turn is adjustably mounted on a mounting part 14 of the frame part 10, as will be discussed in more detail below.

The pressure bar 11 faces the lateral side 6 of the wing 4. In the embodiment of the Fig. 2 and 3 a profile seal 15 is attached to the wing 4 and its lateral side 6, for example glued or clamped in grooves (not shown). Both the pressure bar 11 and the profile seal 15 have here approximately Z-shaped cross-section. The one leg 15 'of the Z of the profile seal 15 is glued to the lateral side 6 and the web 15 "of the Z profile seal 15 on the edge region of the outer side 8 of the wing 4, the other leg 15"' of the Z of the profile seal 15, however, is about normal to the level of the wing 4 from the outside 8 and forms a lip 16th

The frame part 10 has a lip 16 like a hat and with game cross-stop bar 17 to provide there at the same time a cover against the weather. The stop bar 17 can be made in one piece with the frame part 10 or placed on this, as shown.

Upon actuation of the sealing device according to Fig. 3 presses the pressure bar 11 with its normal to the wing plane, parallel to the displacement direction 5 first leg 11 'against the first leg 15' of the profile seal 15; the web 11 "of the pressure bar 11 slides at a distance over the web 15" of the profile seal 15; In this intermediate space, water, eg condensation water, can drain off. With its normal to the wing plane, parallel to the direction of displacement 5 second leg 11 '' presses the pressure bar 11 against the lip 16, which in turn comes to rest against the stop bar 17, that is pressed between pressure bar 11 and stop bar 17.

Alternatively, the first leg 15 'of the profile seal 15 can be omitted, so that the pressure bar 11 with its first leg 11' comes to rest directly on the lateral side 6 of the wing 4 when actuated. The pressure bar 11 could also be equipped with a sealing profile itself. The stop bar 17 can also be dispensed with and the sealing action on the lip 16 can be achieved only by pressing the second leg 11 '' of the pressure bar 11. Alternatively, the lip 16 and second leg 11 '' of the pressure bar 11 on the one hand or the first leg 11 'of the pressure strip 11 on the other hand omitted and the sealing effect of the sealing device while only between pressure bar 11 and lateral side 6 of the wing 4 or profile seal 15 or on the other hand only between the second leg 11''the pressure bar 11 and lip 16 are achieved with or without stop bar 17 Also lateral side 6, profile seal 15, pressure bar 11 and / or stop bar 17 could be at the respective pressing surfaces other than in the Fig. 2 and 3 have shown cross-sectional profile, for example stepped or curved, have additional sealing profiles and / or the profile seal 15 via additional sealing lugs 18, as in Fig. 2 recognizable.

The Fig. 4 and 5 illustrate the displacement of the sealing device from the in Fig. 2 shown open position in the in Fig. 3 shown closing and sealing position (and vice versa) by means of a coupling member which translates the closing force of the closing wing 4 in a pressing force for pressing the pressure bar 11. As a coupling member here serves a stop 20 at one end of the pressure bar 11 for a driver 21 of the wing 4. The stop 20 protrudes into the trajectory of the wing 4, so that the wing 4 when moving from its open position ( Fig. 2 . Fig. 5a ) just before reaching its closed position ( Fig. 5b ) with its front side 7 as a driver 21 comes to the stop 20 to the plant and then operated with this pressure bar 11 and moved until it is in its closed position ( Fig. 3 . Fig. 5c ) reached.

The pressure bar 11 is mounted by means of two oblique scenes 22, in which each of the sliding member 13 of the support member 12 engages the frame member 10 in the wing plane and obliquely to the direction of displacement 5 movable. One or more than two scenes 22 can also be used and interact with a corresponding number of sliding elements 13. The gate 22 could also be formed as a groove or a web guiding the sliding element 13 instead of as an oblong hole, as shown, and / or image a more complex linear course than that shown, e.g. curved toward the lateral side 6 of the wing 4 in order to achieve a desired movement of the pressure bar 11.

It is understood that stop 20 and driver 21 can also be arranged at a location other than the end of the pressure bar 11 and the end face 7 of the wing 4; also that the scenes 22 may be reversed on the frame part 10 and the sliding elements 13 may be formed on the pressure bar 11 or any other known in the art inclined position of the pressure bar 11 relative to the frame part 10 may be provided to achieve the described function.

When opening the wing 4, the pressure bar 11 is initially driven by this because of their sealing pressure on the lateral side 6 or profile seal 15 until the slide 22 and slide 13 to lift them off and release the wing 4. In the viewing direction of Fig. 2 It can be seen that the wing 4 and the profile seal 15 in the open position of the sealing device in the direction of displacement 5 are freely movable.

As an alternative to stop 20 and driver 21 could also be a frame member 10 mounted on the wing 4 on reaching its closed position operable lever mechanism (not shown) act as a coupling member on the pressure bar 11. In this case, the pressure bar 11 depending on their storage on the frame part 10 and depending on the lever mechanism and any other movement, for example, normal to the lateral side 6 of the wing 4 and / or obliquely to the wing plane, run.

According to the Fig. 2-4 can be obtained via a recess 23 in the pressure bar 11 in any position of the pressure bar 11 access to a slot 24 in the support member 12 of the frame part 10, which is extended in the direction 5 to set the support member 12 via mounting bolts 25 adjustable on the mounting member 14. An adjustment of the support member 12 in the direction of displacement 5 adjusts the position of its sliding elements 13 with respect to the slide 22 of the pressure bar 11 and thus allows an adjustment of the pressing action of the pressure bar 11 during the closing movement of the wing. 4

The wing 4 can be single or mehrscheibig, zB dreischeibig as in the Fig. 2 and 3 , with intermediate spacers 26, also frameless, executed.

In the embodiment shown, the frame part 10 has approximately the shape of a U-profile, which surrounds the wing 4 on its lateral side 6. In the U-profile opening 27 of the frame part 10 of the wing 4 is slidably supported by a carrier 28 in a linear bearing 29. Alternatively, the wing 4 could also have a frame which is supported directly by the linear bearing 29. In particular, when the sliding window 1 is to be installed vertically, the carrier 28 can surround the wing 4 symmetrically. As a linear bearing 29 is any known in the art bearings, such as a sliding or rolling bearings. That in the Fig. 2 and 3 shown linear bearing 29 is duplicated, but could also be one or more times.

As the Fig. 2 and 3 Furthermore, the U-profile opening 27 of the frame part 10 can also form a compartment 30 for receiving a spindle drive 31 for displacing the wing 4. For this purpose, the carrier 28 is extended into the compartment 30 and equipped with a spindle nut 32 which engages around a threaded rod 33. The threaded rod 33 can directly or via a gear (not shown) by hand or motor are driven. If the sliding window 1 has a second displaceable wing 4 ', it can either be actuated by its own spindle drive, which is driven autonomously or by the abovementioned spindle drive, for example via an optional reduction gear, or by means of stops and drivers from the first wing 4. As an alternative to a spindle drive 31, other linear drives known in the art may also be used.

The sealing device may further be equipped with one or more brush seals 34 mounted on the frame part 10, which come to rest on the outside 8 of the wing, the profile seal 15, as it were, in order to keep out the weather from it.

The sealing device is not only on the in Fig. 1 shown sliding window 1 for roof slopes, but also such for flat roofs or vertically integrated in building facades sliding window 1, both with horizontally and vertically up or down sliding wings 4, 4 ', as well as for sliding doors or the like. used. It may also be sufficient in some cases, the sealing device only on one of the two lateral sides 6 of a sliding wing 4, 4 ', for example, the lower lateral side 6 of a sliding door provided.

The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims.
