[0009] In contrast, the present invention aims to provide a window or door having at least two movable sashes which can be connected to each other independently of one another in an intuitive and tightly connected manner. Furthermore, the present invention aims to provide a method for opening the window or door.

[0010] 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 in the claims.

[0011] The object according to the invention is achieved by a window or a door, wherein the window or the door has the following features:

[0012] a) fixed frame;

[0013] b) a first leaf, which is movable in a direction transverse to its main plane from a closed position into a displaced position, wherein in the displaced position the first leaf is displaceable in the direction of its main plane;

[0014] c) a second leaf, which is movable from a closed position in a direction transverse to its main plane into a displaced position, wherein in the displaced position the second leaf is displaceable in the direction of its main plane;

[0015] d) when the two leaves are in the closed position, the leaves overlap;

[0016] e) a first transmission rod assembly on the first leaf and a first handle coupled to the first transmission rod assembly so that the first leaf can be moved into the moved position independently of the second leaf by actuating the first handle;

[0017] f) a second transmission rod assembly on the second leaf and a second handle coupled to the second transmission rod assembly so as to move the second leaf into the shifted position independently of the first leaf by actuating the second handle;

[0018] g) a locking pin on the first transmission rod assembly, the locking pin being movable transversely to the main plane of the first sash;

[0019] h) A locking element on the second transmission rod assembly that can be engaged from behind by a locking pin and that can be moved transversely to the main plane of the second leaf.

[0020] The arrangement of at least two leaves overlapping in the closed position is also called "D-type." According to the invention, the elements that can move independently of each other, ie the locking pin and the locking member, allow intuitive operation of the two leaves (opening and closing or connecting them to each other).

[0021] Preferably, the locking pin and / or the locking element are movable perpendicularly to the main plane of the respective leaf.

[0022] The locking element can have a through-recess, in particular a slot-shaped or Ω-shaped through-recess. The through-recess can have a recess, into which a widened, in particular mushroom-shaped, end section of the locking pin engages in the closed position of the two leaves, so that the leaves can no longer move. This achieves a particularly break-proof locking of the two leaves to one another. Preferably, the widened end section only engages in the recess when the two leaves are in the closed position. In all other positions, the widened end section preferably does not engage in the recess, so that the leaves can move in the movable position.

[0023] The first leaf can include a first sliding unit. The first sliding unit can include a first sliding member with a first guide groove. The first guide groove can extend at least partially obliquely to the longitudinal axis of the first transmission rod. The first transmission rod can be constructed in one piece or in multiple pieces. A first bolt can be guided in the first guide groove, and the first bolt can be arranged or constructed on the first transmission rod. The locking pin can be arranged or constructed on the first sliding member. Movement of the first transmission rod in the direction of its longitudinal axis can thereby achieve movement of the locking pin transversely to, and in particular perpendicular to, the longitudinal axis.

[0024] The second leaf can include a second sliding unit. The second sliding unit can include a second sliding member with a second guide groove. The second guide groove can extend at least partially 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 the second guide groove, and the second bolt can be arranged or constructed on the second transmission rod. The locking member can be arranged or constructed on the second sliding member. Movement of the second transmission rod in the direction of its longitudinal axis can thereby achieve movement of the locking member transversely to, and in particular perpendicular to, the longitudinal axis.

[0025] The first sliding unit and the second sliding unit are preferably of identical design. By using standard parts, the window or door can be constructed particularly simply and cost-effectively in terms of construction.

[0026] The second leaf can have a third sliding unit. The third sliding unit can have a third sliding member with a third sliding groove. The third sliding groove can extend at least partially obliquely to the longitudinal axis of the second transmission rod. A third bolt can be guided in the third sliding groove, and the third bolt is arranged or constructed on the second transmission rod. The locking member can be arranged or constructed on the third sliding member. The third sliding member can be connected to the second sliding member via the locking member. The movement of the second transmission rod in the direction of its longitudinal axis can thereby achieve a particularly reliable and non-tilting movement of the locking member transversely to, and in particular perpendicular to, the longitudinal axis.

[0027] The second sliding unit and the third sliding unit are preferably designed identically.

[0028] The first transmission rod assembly can have a slide on the underside of the first leaf, by means of which the first leaf can be moved transversely, in particular perpendicularly, to a main plane of the first leaf.

[0029] The movability of the underside of the first leaf preferably corresponds to the movability of the locking pin in the opposite direction (in particular minus the penetration depth of the widened end section of the locking pin into the recess of the closure element).

[0030] The carriage can include a sliding element with a guide groove in which a bolt is guided. The bolt is arranged or formed on the transmission rod of the first transmission rod assembly. At least one pulley of the carriage can be arranged on the sliding element and supported relative to a fixed frame, in particular a guide rail of the fixed frame. The guide groove can be designed identically to the first guide groove or in a mirror-image manner.

[0031] The second transmission rod assembly can have a slide on the underside of the second leaf, by means of which the second leaf can be moved transversely, in particular perpendicularly, to a main plane of the second leaf.

[0032] The movability of the underside of the second leaf preferably corresponds to the movability of the locking element in the opposite direction (in particular, minus the penetration depth of the widened end section of the locking pin into the recess of the locking element). Particularly preferably, the movability of the underside of the second leaf corresponds to the movability of the underside of the first leaf.

[0033] The carriage can include a sliding element with a guide groove in which a bolt is guided. The bolt is arranged or formed on the transmission rod of the second transmission rod assembly. At least one pulley of the carriage can be arranged on the sliding element and supported relative to a fixed frame, in particular a guide rail of the fixed frame. The guide groove can be designed identically to the first guide groove or in a mirror-image manner.

[0034] The first transmission rod assembly can have a sliding body on the upper side of the first leaf, by which the first leaf can be moved transversely, in particular perpendicularly, to the main plane of the first leaf. The sliding body can have a roller, with which the sliding body is supported on a fixed frame and rolls along the frame.

[0035] The movability of the upper side of the first leaf preferably corresponds to the movability of the locking pin in the opposite direction (in particular, minus the penetration depth of the widened end section of the locking pin in the recess of the closure element). Particularly preferably, the movability of the upper side of the first leaf corresponds to the movability of the lower side of the first leaf.

[0036] The sliding body can include a sliding element with a guide groove in which a pin is guided. The pin is arranged or formed on the transmission rod of the first transmission rod assembly. The sliding element can be supported indirectly or directly relative to the fixed frame. The guide groove can be designed identically to the first guide groove or in a mirror-image manner.

[0037] The second transmission rod assembly can have a sliding body on the upper side of the second leaf, by means of which the second leaf can be moved transversely, in particular perpendicularly, to a main plane of the second leaf.

[0038] The movability of the upper side of the second leaf preferably corresponds to the movability of the locking element in the opposite direction (in particular, minus the penetration depth of the widened end section of the locking pin into the recess of the locking element). Particularly preferably, the movability of the upper side of the second leaf corresponds to the movability of the lower side of the second leaf.

[0039] The sliding body can include a sliding element with a guide groove in which a pin is guided. The pin is arranged or formed on the transmission rod of the second transmission rod assembly. The sliding element can be supported indirectly or directly relative to the fixed frame. The guide groove can be designed identically to the first guide groove or in a mirror-image manner.

[0040] The aforementioned slides and / or sliding bodies enable a completely collision-free arrangement of the two leaves in any desired closed or displaced position.

[0041] The two leaves are preferably movable in opposite directions from their closed position into their displaced position. Further preferably, the two leaves are respectively movable transversely to their main plane away from each other from their closed position into their displaced position.

[0042] In a further preferred embodiment of the invention, the window or door has a sealing strip on the fixed frame between the first and second sashes, the first sash resting on the sealing strip in its closed position, and the second sash resting on the opposite side of the sealing strip in its closed position. This achieves a very reliable seal of the window or door.

[0043] Particularly preferably, the sealing strip is arranged or formed circumferentially on the fixed frame, however at least on the horizontal upper and lower beams of the fixed frame.

[0044] In the overlapping area of ​​the locked sashes, a sealing strip can be arranged on one or both sashes to provide a seal between them. The same sealing strip can be used on both sashes. The sealing strips of the two sashes can touch each other, thus forming a common seal in the area between them. However, it is also possible to use a sealing strip on one or both sashes that seals directly on the other sash contour. This, together with the sealing strip on the fixed frame, forms a circumferential sealing surface that is particularly well sealed and therefore prevents seal deviations.

[0045] Any gap between the fixed frame and the overlapping region of the closed sash can be closed by a molded part designed as a sealing gasket.

[0046] Furthermore, the object according to the invention is achieved by a method for opening a window as described herein or a door as described herein, which method comprises the following method steps:

[0067] Figure 1 A door 10 is shown having a sash or fixed frame 12, a first leaf 14a, and a second leaf 14b. The first leaf 14a has a first handle 16a connected to a first drive rod assembly 18a. The first drive rod assembly 18a has a locking pin 20. The locking pin 20 is used to lock onto a locking member 22 of the second leaf 14b.

[0068] Figure 2 Shown from Figure 1 The door 10 has a swinging first handle 16a. The swinging of the first handle 16a is achieved by means of a first transmission rod assembly 18a to move the locking pin 20. The first leaf 14a is forcibly controlled to move from its position in the door by swinging the first handle 16a. Figure 1 The closed position shown in FIG moves to Figure 2In the mobile position shown in .

[0069] Figure 3 The door 10 is shown from opposite sides with a first leaf 14a and a second leaf 14b. Figure 3 It can be seen that the second leaf 14b has a second handle 16b connected to a second drive rod assembly 18b.

[0070] Figure 4 Shown from Figure 3 The second door 10 is provided with a swinging second handle 16b. The swinging of the second handle 16b enables the locking member 22 to move by means of the second transmission rod assembly 18b. The second leaf 14b is forcibly controlled to move from its position in the swinging direction by the swinging of the second handle 16b. Figure 3 The closed position shown in FIG moves to Figure 4 In the mobile position shown in .

[0071] Figure 5 A portion of the first transmission rod assembly 18a is shown, which includes a first transmission rod 24a and a first sliding unit 26a. The first sliding unit 26a includes a first sliding member 28a with a locking pin 20. The first sliding member 28a has a first guide groove 30a that extends at least partially obliquely to the longitudinal axis of the first transmission rod 24a, in which a first pin 32a arranged or constructed on the first transmission rod 24a is guided. Movement of the first transmission rod 24a causes the locking pin 20 to move transversely, in particular perpendicularly, to the longitudinal axis of the first transmission rod 24a. It is understood that the movement of the locking pin 20 can also be achieved through other embodiments of the movement of the first transmission rod 24a, such as through a transmission mechanism.

[0072] The locking pin 20 has a widened, in particular mushroom-shaped end section 34. The locking pin 20 is opened by moving the leaf 14a, b (see Figure 1 ) can be moved into and out of the through-recess 36. In an alternative embodiment, the end section 34 can be moved into and out of the recess (i.e., 38) of the locking element 22 by moving the locking pin 20 in the direction of its longitudinal axis.

[0073] Figure 6A portion of the second transmission rod assembly 18b is shown, which includes a second transmission rod 24b and a second sliding unit 26b. The second sliding unit 26b includes a second sliding member 28b with a locking member 22. The second sliding member 28b has a second guide groove 30b that extends at least partially obliquely to the longitudinal axis of the second transmission rod 24b, in which a second bolt 32b arranged or constructed on the second transmission rod 24b is guided. Movement of the second transmission rod 24b causes the locking member 22 to move transversely, in particular perpendicularly, to the longitudinal axis of the second transmission rod 24b. It is understood that the movement of the locking member 22 can also be achieved through another embodiment of the movement of the second transmission rod 24b, such as through a transmission mechanism.

[0074] The second transmission rod assembly 18b has, in this example, a third sliding unit 26c, which includes a third sliding element 28c on the locking element 22, so that the locking element 22 can be moved in and out evenly and without tilting. The third sliding element 28c has a third guide groove 30c that extends at least partially at an angle to the longitudinal axis of the second transmission rod 24b, in which a third pin 32c arranged or constructed on the second transmission rod 24b is guided. It is understood that the second and third pins 32b, 32c can also be arranged or constructed on sections of the second transmission rod 24b, wherein the sections are kinematically coupled.

[0075] Figure 7 The door 10 is shown in a cutaway top view. Both the first leaf 14a and the second leaf 14b are in their closed position. In this closed position, the first leaf 14a is at a large distance Ag from the outer side of the fixed frame 12. The second leaf 14b is also at a large distance Bg from the outer side 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. Figure 7 It can be seen that the leaves 14 a, b partially overlap in the region of the locking pin 20 and the locking element 22 .

[0076] Figure 8 Shown door 10 according to Figure 7 , in which the first leaf 14a is in the moved position. The first leaf 14a has a small or reduced distance Ak to the outside of the fixed frame 12. The second leaf 14b still has a large distance Bg to the outside of the fixed frame 12. In addition, the locking pin 20 and the locking part 22 are connected at the distance SE to the fixed frame 12. Therefore, although the first leaf 14a moves towards the outside of the fixed frame 12, it simultaneously moves the locking pin 20 away from the fixed frame 12 by the same length, so that the distance SE remains unchanged (as long as the locking pin 20 does not enter the recess of the locking part 22 (i.e. 38; see Figure 5 )middle).

[0077] Figure 9Show the basis Figure 8 Door 10, wherein the second leaf 14b is in the displaced position. The second leaf 14b has a small or reduced spacing Bk from the outer side of the fixed frame 12. The first leaf 14a has a large spacing Ag from the outer side of the fixed frame 12. In addition, the locking pin 20 and the locking element 22 are engaged at the spacing SE from the fixed frame 12. Therefore, although the second leaf 14b is moved toward the outer side of the fixed frame 12, the locking element 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 locking pin 20 does not enter the recess of the locking element 22 (i.e. 38; see Figure 5 )middle).

[0078] Figure 10 A door 10 is shown with two sashes 14a, b in a movable position, i.e., at a small distance Ak or Bk from a fixed frame 12. The distance SE remains constant in the region of the locking pin 20 or the locking element 22 in this case as well. In this movable position, the sashes 14a, b can each be moved in the direction of their main plane H. The main plane H is the center plane of the frame of the respective sash 14a, b. Measure Ag (see Figure 9 )、Ak、Bg(see Figure 8 ), Bk and SE are measured perpendicular to the main plane H.

[0079] Figure 7 and 10 The overview shows that when the first leaf 14a is moved from the distance Ag to Ak by the distance Ag-Ak, the locking pin 20 is also moved by the distance Ag-Ak, but in the opposite direction. Furthermore, it can be seen that when the second leaf 14b is moved from the distance Bg to Bk by the distance Bg-Bk, the locking element 22 is also moved by the distance Bg-Bk, but in the opposite direction. Particularly preferably, the distance Ag-Ak corresponds to the distance Bg-Bk.

[0080] exist Figure 10 Optional seals 40a, 40b are shown as dashed lines on sashes 14a, b. Seals 40a, b are used to seal sashes 14a, b from one another in their overlapping areas or at center seams 42. Seals 40a, b are preferably identically configured and / or symmetrically arranged relative to one another. Each seal may include a seal receiving portion 44a, 44b and a sealing strip 46a, 46b arranged or configured on the seal receiving portion.

[0081] Figure 11 The door 10 is shown with the sashes 14a, b in the closed position. Figure 11It can be seen that the sashes 14a, b are supported on the lower side by slides 48a, 48b and on the upper side by slides 50a, 50b relative to the fixed frame 12. The slides 48a, b and the slides 50a, b are positively controlled with respect to the fixed frame 12 (see FIG. Figure 5 , 6) are connected to the transmission rod assembly 18a, b for moving the leaves 14a, b from the closed position to the moving position. In the closed position, the leaves 14a, b rest on the sealing strip 52 of the fixed frame 12. In the overlapping area of ​​the two leaves 14a, b, the optional seals 40a and 40b can be seen, which are here (as in Figure 10 The panels 14a, b are in contact with each other (differently in FIG) and thus form a common seal in the area between the panels 14a, b.

[0082] Figure 12 Show the basis Figure 11 The door 10 of FIG. 1 is shown in FIG. 1 , wherein the leaves 14 a, b are in the said displacement position. In this position, the leaves 14 a, b do not rest on the sealing strip 52. The sealing strip 52 is parallel to the main planes and is located in the middle between the main planes H (see FIG. Figure 10 The sealing strip 52 is also preferably located centrally in the door 10 and preferably forms a vertical plane of symmetry.

[0083] Depend on Figure 11 and 12 As can be seen from the overview, the leaves 14a, b can be moved out in opposite directions, ie can be transferred from their respective closed position into their respective moved position.

[0084] Figure 13 Show the basis Figure 7 The door 10 has a fixed frame 12, sashes 14a, b, seals 40a, b and a sealing strip 52, wherein the seals 40a, b respectively form a non-deflected sealing plane with the sealing strip 52.

[0085] In general terms, the present invention relates to a door 10 or window having at least two sashes 14a, b, with an overview of all views of the accompanying drawings. Each of the at least two sashes 14a, b has a drive rod assembly 18a, b. The first drive rod assembly 18a preferably includes a locking pin 20 having a widened end section 34. The second drive rod assembly 18b preferably includes a locking member 22 for receiving the widened end section 34. The first drive rod assembly 18a is specifically configured to move the widened end section 34 onto the second sash 14b when the first sash 14a moves from a closed position to a movable position. The first sash 14a preferably moves the same distance during this movement, but in opposite directions. The second drive rod assembly 18b is specifically configured to move the locking member 22 onto the first sash 14a when the second sash 14b moves from a closed position to a movable position. The second sash 14b preferably moves the same distance during this movement, but in opposite directions. The distance over which the first leaf 14a can be moved from the closed position into the displaced position preferably corresponds to the distance over which the second leaf 14b can be moved from the closed position into the displaced position.
