Description

D-shaped window or door closure and method for opening a window or door

Technical Field

The invention relates to a window or door having at least two movable leaves which, in the closed state, overlap transversely to their main plane. Furthermore, the invention relates to a method for opening the window or the door.

Background

EP 0 546 336 A1 discloses a blocking element for a sliding window or a sliding door. The blocking element has a movable blocking element on the end face of the leaf of the sliding window or sliding door.

A window or door with two movable leaves is known from WO 2012/093382 A1. The fan can be locked to the fixed frame by a locking mechanism ("locking mechanism 180"). A seal ("inter-panel seal 145") may be provided between the fans.

EP 3 192 951 A1 discloses a sliding door with a particularly liftable door leaf. A movable bolt is provided on the end face of the door leaf for engaging behind the locking element on the fixed frame in order to lock the door leaf on the fixed frame.

A locking assembly is known from EP 2 682 545 A1 in order to lock a movable fan relative to a stationary region. The locking assembly has a movable locking bolt which can be engaged with a fixedly mounted locking member.

DE 29 776 A1 discloses a closure mechanism for a sliding door or window with two sliding leaves. Here, a lever is provided on one moving fan. By pivoting the lever, the moving leaf is locked to a pivotable locking member on the other moving leaf. The pivoting of the lever and of the blocking element each effect a displacement of the respective displacement fan transversely to the displacement direction. The oscillation of the lever thus achieves the simultaneous locking of the two moving fans.

DE 10 2018 110 A1 discloses an anti-mishandling device for wings of a window or door that can be moved together at the end.

EP 2 860 333 A1 discloses a locking assembly for locking two moving fans. The locking assemblies can each have a claw on the end face of the moving fan, which claw can be moved perpendicular to the fan plane.

Disclosure of Invention

In contrast, the object of the present invention is to provide a window or door having at least two movable leaves which, independently of one another, can be connected to one another both intuitively and tightly. The object of the invention is also to provide a method for opening the window or the door.

According to the invention, this object is achieved by a window or door according to claim 1 and a method according to claim 14. Preferred further developments are described from the claims.

The object according to the invention is thus achieved by a window or door, wherein the window or door has the following features:

a) A fixed frame;

b) A first fan movable in a direction transverse to its main plane from a closed position into a moved position, wherein the first fan is movable in the moved position in the direction of its main plane;

c) A second fan movable from a closed position into a moved position in a direction transverse to its main plane, wherein the second fan is movable in the moved position in the direction of its main plane;

d) When the two fans are in the closed position, the fans overlap;

e) A first transfer lever assembly on the first fan and a first handle coupled to the first transfer lever assembly for moving the first fan into the mobile position independently of the second fan by manipulating the first handle;

f) A second drive bar assembly on the second fan and a second handle coupled to the second drive bar assembly to move the second fan into the moved position independently of the first fan by manipulating the second handle;

g) A latch pin on the first transfer lever assembly, the latch pin movable transverse to a major plane of the first leaf;

h) A blocking element on the second drive rod assembly, which can be engaged behind by a blocking pin and can be moved transversely to the main plane of the second leaf.

The arrangement of at least two sectors that overlap in the closed position is also referred to as "D-shaped". The elements that can move independently of one another, namely the locking pin and the locking element, allow intuitive operation of the two fans (opening and locking or connecting to one another).

Preferably, the latching pin and/or the latch are movable perpendicular to the main plane of the respective fan.

The blocking element can have a through-opening, in particular a slot-shaped or omega-shaped through-opening. The through-recess can have a recess, with which a widened, in particular mushroom-head-shaped end section of the locking pin engages in the closed position of the two wings, so that the wings can no longer be moved. This achieves a particularly fracture-proof locking of the two fans to one another. Preferably, the widened end section cooperates with the recess only when the two sectors are in the closed position. In all further positions, the widened end section preferably does not engage with the recess, so that the fan can be moved in the moved position.

The first fan may have the first slip unit. The first sliding unit may have a first sliding member with a first sliding groove. The first gate can extend at least in sections obliquely to the longitudinal axis of the first transmission lever. The first gear lever can be constructed in one piece or in several pieces. A first bolt can be guided in the first gate, which is arranged or formed on the first transmission lever. The locking pin can be arranged or formed on the first slide. The first gear lever can thus be displaced in the direction of its longitudinal axis in such a way that the locking pin is moved transversely, in particular perpendicularly, to this longitudinal axis.

The second fan may have a second slip unit. The second sliding unit may have a second sliding member with a second sliding groove. The second link may extend at least in sections obliquely to the longitudinal axis of the second transmission rod. The second transmission rod can be constructed in one piece or in multiple pieces. A second bolt can be guided in a second guide channel, which is arranged or formed on the second transmission lever. The blocking element can be arranged or formed on the second sliding element. The movement of the second transmission lever in the direction of its longitudinal axis can thus effect a movement of the blocking element transverse, in particular perpendicular, to this longitudinal axis.

The first and second displacement units are preferably identically constructed. The use of standard parts makes the window or door particularly simple and inexpensive to construct in terms of construction.

The second fan may have a third slip unit. The third sliding unit can have a third sliding member with a third sliding groove. The third link may extend at least in sections obliquely to the longitudinal axis of the second transmission lever. A third bolt, which is arranged or formed on the second transmission lever, can be guided in a third slide groove. The blocking element can be arranged or formed on the third glide. The third glide may be connected to the second glide by a latch. The displacement of the second transmission lever in the direction of its longitudinal axis can thus achieve a particularly reliable and tilt-free movement of the blocking element transverse, in particular perpendicular, to this longitudinal axis.

The second and third sliding units are preferably identically constructed.

The first gear lever arrangement can have a slide on the underside of the first fan, by means of which slide the first fan can be moved transversely, in particular perpendicularly, to the main plane of the first fan.

The mobility of the lower side of the first leaf preferably corresponds to the mobility of the locking pin in the opposite direction (in particular minus the depth of penetration of the widened end section of the locking pin into the recess of the locking element).

The carriage can have a slide with a sliding groove in which a bolt is guided, which is arranged or formed on the transmission lever of the first transmission lever arrangement. At least one pulley of the carriage can be arranged on the slide, which pulley is supported relative to the fixed frame, in particular the slide rail of the fixed frame. The runner may be constructed identically or as a mirror image to the first runner.

The second drive rod assembly can have a slide on the underside of the second fan, by means of which the second fan can be moved transversely, in particular perpendicularly, to the main plane of the second fan.

The mobility of the underside of the second leaf preferably corresponds to the mobility of the blocking element in the opposite direction (in particular minus the depth of penetration of the widened end section of the blocking pin into the recess of the blocking element). Particularly preferably, the mobility of the underside of the second fan corresponds to the mobility of the underside of the first fan.

The carriage can have a slide with a sliding groove in which a bolt is guided, which is arranged or formed on the drive rod of the second drive rod arrangement. At least one pulley of the carriage can be arranged on the slide, which pulley is supported relative to the fixed frame, in particular the slide rail of the fixed frame. The runner may be configured identically or as a mirror image to the first runner.

The first gear lever assembly can have a sliding body on the upper side of the first leaf, by means of which the first leaf can be moved transversely, in particular perpendicularly, to the main plane of the first leaf. The sliding body may have a roller with which it is supported on a fixed frame and rolls along the frame.

The mobility of the upper side of the first leaf preferably corresponds to the mobility of the locking pin in the opposite direction (in particular minus the depth of penetration of the widened end section of the locking pin into the recess of the locking element). Particularly preferably, the mobility of the upper side of the first fan corresponds to the mobility of the lower side of the first fan.

The slide body can have a slide with a sliding groove in which a bolt is guided, which is arranged or formed on the transmission lever of the first transmission lever arrangement. The glide may be supported indirectly or directly relative to the fixed frame. The runner may be constructed identically or as a mirror image of the first runner.

The second drive rod assembly can have a sliding body on the upper side of the second fan, by means of which the second fan can be moved transversely, in particular perpendicularly, to the main plane of the second fan.

The mobility of the upper side of the second fan preferably corresponds to the mobility of the blocking element in the opposite direction (in particular minus the depth of penetration of the widened end section of the blocking pin into the recess of the blocking element). Particularly preferably, the mobility of the upper side of the second fan corresponds to the mobility of the lower side of the second fan.

The slide body can have a slide with a slide groove in which a bolt is guided, which is arranged or formed on the drive rod of the second drive rod arrangement. The glide may be supported indirectly or directly relative to the fixed frame. The runner may be constructed identically or as a mirror image of the first runner.

The aforementioned slide and/or slide body allows a completely collision-free arrangement of the two fans in any closed or moved position.

The two fans are preferably able to move in opposite directions from their closed position into their moved position. It is further preferred that the two fans can be moved away from each other transversely to their main planes from their closed position into their moved position.

In a further preferred embodiment of the invention, the window or door has a sealing strip on the fixed frame between the first leaf and the second leaf, the first leaf resting against the sealing strip in its closed position and the second leaf resting against the opposite side of the sealing strip in its closed position. A very reliable sealing of the window or door is thereby achieved.

Particularly preferably, the sealing band is arranged or formed around the fixed frame, however at least on the horizontal upper and lower beams of the fixed frame.

A sealing strip may be arranged on one or both of the sectors in the overlapping region of the locked sectors to seal between the two sectors. The same seal can be used on both fans. The sealing strips of the two sectors can be in contact with one another and thus form a common seal in the region between the sectors. However, it is also possible to use sealing strips on one or both sectors, which seal directly on the other sector profile. This, together with the sealing band on the fixed frame, forms a circumferential sealing plane which is sealed particularly well, so that no sealing offset occurs.

Possible gaps between the fixed frame and the overlapping regions of the locked segments can be closed by a molding designed as a gasket.

The object is also achieved according to the invention by a method for opening a window or a door described herein, having the following method steps:

a) Swinging the first handle and thereby moving the locking pin transversely, in particular perpendicularly, to the main plane of the first leaf by means of the first transmission lever assembly;

b) Swinging the second handle and thereby moving the blocking member transversely, in particular perpendicularly, to the main plane of the second fan;

wherein the method steps are only carried out individually, in succession in any desired sequence or simultaneously;

c) The first fan and/or the second fan are moved.

Particularly preferably, the first leaf is moved in method step a) to the same extent as the latching pin (in particular minus the depth of penetration of the widened end section of the latching pin into the recess of the latching element), but in the opposite direction.

It is further preferred that the second leaf is moved in method step B) to the same extent as the locking element (in particular minus the depth of penetration of the widened end section of the locking pin into the recess of the locking element) but in the opposite direction.

Detailed Description

Fig. 1 shows a door 10 having a jamb or fixed frame 12, a first leaf 14a and a second leaf 14b. The first sector 14a has a first handle 16a connected to a first transfer lever assembly 18 a. The first transfer lever assembly 18a has a latch pin 20. The latching pin 20 is used to latch onto a latch 22 of the second leaf 14b.

Fig. 2 shows the door 10 from fig. 1 with a swinging first handle 16a. The swinging of the first handle 16a effects the movement of the latching pin 20 by means of the first transfer lever component 18 a. The first fan 14a is moved in a positively controlled manner from its closed position shown in fig. 1 into its moved position shown in fig. 2 by pivoting the first handle 16a.

Fig. 3 shows the door 10 with the first leaf 14a and the second leaf 14b from opposite sides. As can be seen in FIG. 3, the second fan 14b has a second handle 16b that is connected to a second drive rod assembly 18 b.

Fig. 4 shows the door 10 from fig. 3 with the swinging second handle 16 b. The pivoting of the second handle 16b effects the movement of the blocking member 22 by means of the second drive rod assembly 18 b. The second fan 14b is moved in a positively controlled manner from its closed position shown in fig. 3 into its moved position shown in fig. 4 by pivoting the second handle 16 b.

Fig. 5 shows a portion of the first transfer lever assembly 18a having a first transfer lever 24a and a first glide unit 26 a. First slide unit 26a has a first slide 28a with locking pin 20. The first slide 28a has a first slide groove 30a, which extends at least in sections at an angle to the longitudinal axis of the first drive rod 24a and in which a first bolt 32a arranged or formed on the first drive rod 24a is guided. Movement of the first transfer lever 24a effects movement of the locking pin 20 transverse, in particular perpendicular, to the longitudinal axis of the first transfer lever 24 a. It is understood that the described movement of the locking pin 20 can also be achieved by a further embodiment of the movement of the first transmission lever 24a, for example by a transmission mechanism.

The locking pin 20 has a widened, in particular mushroom-head-shaped end section 34. The latching pin 20 can be moved into and out of the through-recess 36 by moving the sectors 14a, b (see fig. 1). In an alternative embodiment, end section 34 may be moved into and out of a recess (i.e., 38) of latch 22 by moving latching pin 20 in the direction of its longitudinal axis.

Fig. 6 shows a portion of the second drive rod assembly 18b with a second drive rod 24b and a second displacement unit 26 b. The second sliding unit 26b has a second sliding part 28b with a blocking part 22. The second slide 28b has a second gate 30b, which extends at least in sections at an angle to the longitudinal axis of the second transmission lever 24b and in which a second pin 32b, which is arranged or formed on the second transmission lever 24b, is guided. The movement of the second transmission lever 24b effects a movement of the blocking element 22 transversely, in particular perpendicularly, to the longitudinal axis of the second transmission lever 24 b. It is to be understood that the movement of the blocking element 22 can also be realized by a further embodiment of the movement of the second transmission lever 24b, for example by a transmission mechanism.

The second drive rod assembly 18b has in the example shown a third sliding unit 26c with a third sliding part 28c on the blocking member 22, so that the blocking member 22 can be moved in and out uniformly and without tilting. The third slide 28c has a third slide groove 30c, which extends at least in sections at an angle to the longitudinal axis of the second transmission rod 24b and in which a third pin 32c arranged or formed on the second transmission rod 24b is guided. It is to be understood that the second pin 32b and the third pin 32c can be arranged or formed on a section of the second transmission lever 24b, wherein the sections are kinematically coupled.

Fig. 7 shows the door 10 in a sectional top view. Not only the first sector 14a but also the second sector 14b is in its closed position. In the closed position, the first leaf 14a has a large distance Ag to the outside of the fixed frame 12. The second fan 14b likewise has a large distance Bg to the outside of the fixed frame 12. The locking pin 20 and the locking element 22 engage at a distance SE (locking plane) from the fixed frame 12. It can be seen from fig. 7 that the leaves 14a, b partially overlap in the region of the latching pin 20 and the latching member 22.

Fig. 8 shows the door 10 according to fig. 7, wherein the first leaf 14a is in the shifted position. The first fan 14a has a small or reduced distance Ak from the outside of the fixed frame 12. The second fan 14b always has a large distance Bg to the outside of the fixed frame 12. Furthermore, the locking pin 20 and the locking element 22 engage at a distance SE from the fixed frame 12. Thus, the first leaf 14a, although moving towards the outside of the fixed frame 12, simultaneously moves the latching pin 20 away from the fixed frame 12 by the same length, so that the spacing SE remains unchanged (as long as the latching pin 20 does not enter into the recess (i.e. 38; see FIG. 5) of the latching member 22).

Fig. 9 shows the door 10 according to fig. 8, wherein the second leaf 14b is in the shifted position. The second fan 14b has a small or reduced distance Bk from the outside of the fixed frame 12. The first fan 14a has a large spacing Ag from the outside of the fixed frame 12. Furthermore, the locking pin 20 and the locking element 22 engage at a distance SE from the fixed frame 12. Thus, while the second leaf 14b moves toward the outside of the fixed frame 12, the latch 22 is simultaneously moved away from the fixed frame 12 by the same length, so that the spacing SE remains unchanged (as long as the latch pin 20 does not enter the recess (i.e., 38; see FIG. 5) of the latch 22).

Fig. 10 shows a door 10 with a small distance Ak or Bk from a fixed frame 12 in the shifted state. Two fans 14a, b. The spacing SE also remains constant in this case in the region of the locking pin 20 or locking element 22. In the shifted position, the fans 14a, b can be shifted in the direction of their main plane H, respectively. The main plane H is the central plane of the frame of the respective fan 14a, b. The measurements Ag (see fig. 9), ak, bg (see fig. 8), bk and SE are measured perpendicular to the principal plane H.

The overview of fig. 7 and 10 shows that, when the first leaf 14a is moved from the distance Ag to Ak by the distance Ag — Ak, the same movement of the locking pin 20 by the distance Ag — Ak is carried out, but in the opposite direction. It can also be seen that the movement of the blocking element 22 by the distance Bg-Bk, but in the opposite direction, likewise takes place when the second fan 14b moves from the distance Bg to Bk by the distance Bg-Bk. The spacing Ag-Ak here corresponds particularly preferably to the spacing Bg-Bk.

In FIG. 10,

optional seals

40a,40b are shown in phantom on fans 14a, b. The seals 40a, b serve to seal the leaves 14a, b to one another in their overlapping region or on the intermediate seam 42. The sealing parts 40a, b are preferably identically constructed and/or symmetrically arranged with respect to one another. The seals may have

seal receiving portions

44a,44b, respectively, and

seal strips

46a,46b disposed or configured thereon.

Fig. 11 shows the door 10 with the leaves 14a, b in the closed position. As can be seen from fig. 11, the fans 14a, b are supported on the underside by the sliders 48a,48b and on the upper side by the

sliders

50a,50b relative to the stationary frame 12. The carriages 48a, b and sliders 50a, b are positively connected to drive rod assemblies 18a, b (see 5,6) for moving the fans 14a, b from the closed position into the moved position. In the closed position, the fans 14a, b rest on the sealing strip 52 of the fixed frame 12. In the overlapping region of the two leaves 14a, b,

optional seals

40a and 40b can be seen, which here (in contrast to fig. 10) contact one another and thus form a common seal in the region between the leaves 14a, b.

Fig. 12 shows the door 10 according to fig. 11, wherein the leaves 14a, b are in the shifted position. In this position, the fans 14a, b do not rest against the sealing strip 52. The sealing band 52 is parallel to the main planes and is located midway between the main planes H (see fig. 10). The sealing band 52 is furthermore preferably located centrally in the door 10 and preferably forms a vertical plane of symmetry.

From the overview of fig. 11 and 12, it can be seen that the sectors 14a, b can be moved out in the opposite direction, i.e. can be transferred from their respective closed position into their respective moved position.

Fig. 13 shows the door 10 according to fig. 7 with the fixed frame 12, the leaves 14a, b, the seals 40a, b and the sealing strip 52, wherein the seals 40a, b each form a sealing plane with the sealing strip 52 without offset.

In the case of all views of the drawing, the invention relates in general terms to a door 10 or window with at least two leaves 14a, b. Each of the at least two fans 14a, b has a drive link assembly 18a, b. The first transfer lever assembly 18a preferably includes a latch pin 20 having a widened end section 34. The second drive rod assembly 18b preferably includes a latch 22 for receiving the widened end section 34. The first drive rod assembly 18a is in particular designed to move the widened end section 34 onto the second leaf 14b when the first leaf 14a is moved from the closed position into the moved position. The first fan 14a preferably moves the same distance in this movement, but in the opposite direction. The second lever arrangement 18b is in particular designed to move the blocking member 22 onto the first leaf 14a when the second leaf 14b is moved from the closed position into the moved position. The second fan 14b preferably moves the same distance in this movement, but in the opposite direction. The distance that the first fan 14a can be moved from the closed position into the moved position preferably corresponds to the distance that the second fan 14b can be moved from the closed position into the moved position.
