The invention relates to a slide-and-swing sash system in accordance with the preamble of claim 1.
Such slide-and-swing sash systems are sufficiently known. They have multiple window sashes, which can be pivoted individually, and thereby a façade division or room partition, which is generally very large, can be opened almost completely. The individual sashes are displaceably guided in guide rails arranged on the ceiling and on the floor. In this regard, each sash is displaceably held in a ceiling profile by way of two support elements. On the floor side, each sash is guided in the floor rail, generally by way of a carriage part. To pivot a sash, the guide rails have an outlet opening for unlatching a support element or a guide carriage of a sash. A slide-and-swing sash system of the above type is described, for example, in EP 2 546 441 A1. An outer sash of the slide-and-swing sash system functions as a door sash that can be pivoted into the remaining opening in the latched state of all the other sashes, and thereby the façade division or room partition is completely closed. In order to prevent unauthorized opening, this door sash is provided with a closure mechanism that prevents the door sash from being pivoted out. Such a closure mechanism is regularly configured in the form of a latch that is guided in a guide on the sash and can be introduced into a rail.
It is a disadvantage of the known closure mechanism that the latch has only a slight insertion depth in the rails, which run horizontally. As soon as the door sash is subject to horizontal stress, for example due to wind, the locking device can fail and therefore the sash can open unintentionally.
This is where the invention wishes to provide a remedy. The invention is based on the task of making available a slide-and-swing sash system having a closure mechanism that guarantees reliable latching even in the event of horizontal stress on the door sash due to wind. According to the invention, this task is accomplished by means of a slide-and-swing sash system having the characteristics of the characterizing part of claim 1.
With the invention, a slide-and swing sash system having a closure mechanism is made available, which mechanism guarantees reliable latching even in the event of a horizontal wind load on the door sash. Because of the fact that the closure mechanism comprises an operating part by way of which a drive can be activated, by way of which drive the door sash can be displaced in the rail profile, in the direction of the adjacent sash, to such an extent that no support element aligns with the outlet opening, exiting of a support element through the lateral outlet opening is reliably prevented. Preferably, a ceiling rail profile and a floor rail profile are provided, which each have a lateral outlet opening and in which the at least two sashes are guided.
The term “floor part” should be understood to mean any device for activation of a drive, such as a button for activation of an electrical, pneumatic or hydraulic drive, or an operating lever for activation of a mechanical drive.
In a further development of the invention, the operating part is an operating lever, and the drive is a mechanical drive that is configured in such a manner that a rotational movement of the operating lever can be converted to a horizontal movement of the door sash along the rail profile or parallel to it, wherein the operating lever can be locked in place, preferably at least in the closed position. It is advantageous if the operating lever can additionally be locked in place, thereby preventing unauthorized opening. Preferably a side profile is arranged orthogonal to the at least one rail profile, which side rail forms a counter-bearing for the drive.
In an embodiment of the invention, the drive is arranged on the door sash and has a thrust element that is connected with a side profile that is provided and can be moved out against the side profile by means of rotation of the operating lever, which profile functions as a counter-bearing, and thereby a thrust force on the door sash is brought about. In this way, mechanically reliable displacement of the door sash is made possible.
In a further development of the invention, a holding block is provided in the side profile, which block has a holder for the thrust element, into which the thrust element engages in the pivoted-in position of the door sash. In this way, the thrust element is fixed in place on the side profile in the closed position of the door sash.
In a further embodiment of the invention, the drive is arranged on the side profile and has a thrust element that is connected with the door sash with shape fit in the pivoted-in position of the door sash, wherein the thrust element can be moved out against the door sash by means of rotation of the operating lever, thereby bringing about a thrust force on the door sash.
In a further development of the invention, a mushroom head is arranged on the door sash, which head engages into a T-shaped recess of the thrust element when the door sash is pivoted in.
In a further embodiment of the invention, the drive is arranged on a side profile and comprises a thrust rod that can be displaced vertically by means of rotation of the operating lever, and is connected with a thrust piece that is connected with the door sash, by way of a transformation arrangement, wherein the transformation arrangement is set up for transforming a vertical movement of the thrust rod into a horizontal movement of the thrust piece. In this way, a drive that can be positioned at a position of the side profile that cannot be seen is made possible, which drive is arranged outside of the door sash. In this way, modification of a sash for use as a door sash is made unnecessary. The term “transformation arrangement” should be understood to mean an arrangement of components, by way of which transformation or redirection of a vertical movement of a thrust rod into a horizontal movement of a thrust element is made possible. Preferably the transformation arrangement has a cam disk, a crank drive or a gearwheel mechanism for redirection of a vertical movement of the thrust rod into a horizontal movement of the thrust piece.
In a further development of the invention, the transformation arrangement comprises a compulsory guide that is connected with the thrust piece and in which an entrainer part connected with the thrust rod is guided. In this regard, the entrainer part is preferably formed by a slide pin preferably set against the thrust rod at an angle, which pin is guided in the channel of the compulsory guide. It is advantageous if the slide pin is set against the thrust rod at an angle of between 30° and 55°, preferably between 35° and 50°, particularly preferably of 45°. The translation between thrust rod and slider can be adjusted by way of the angle of the slide pin. At a preferred angle of 45°, maximum horizontal movement of the slider during vertical movement of the thrust rod is achieved.
In an embodiment of the invention, the slider is connected with a support element of the door sash. In this way, a covered connection of the slider with the door sash is made possible. Preferably the slider projects into a rail profile, and thereby it is completely covered.
In a further development of the invention, the slider is connected with the support element of the door sash on the ceiling side. In this way, the risk of tilting of the door sash is reduced.
In an embodiment of the invention, a clamping piece is mounted in the side profile so as to pivot, which piece surrounds the door sash in the closed position. In this way, the door panel is laterally stabilized in the closed position. At the same time, the clamping piece bridges the distance from the side profile that occurs as the result of the displacement of the door sash.
In a further embodiment of the invention, the clamping piece has two holding arms arranged opposite one another, between which the door sash slides when it is pivoted into the closed position, and out of which it slides when it is pivoted out of the closed position. In this way, automatic fixation of the door sash is achieved when it is pivoted into the closed position. Preferably, one arm is straight and the opposite arm is configured angled away relative to the first arm. In this way, a clamping effect is achieved when the door sash slides in.
In a further development of the invention, a bearing block is introduced into the side profile, which block has an axle holder into which an axle of the clamping piece engages, wherein the clamping piece is guided in the side profile by means of a recess introduced into the side profile for this purpose. In this way, stable and, at the same time, easily installed pivoting mounting of the clamping piece on the side profile is achieved. Preferably the outer contour of the bearing block is configured in accordance with the inner contour of the side profile. In this way, shape-fit attachment is brought about. In this regard, the bearing block is particularly preferably produced from an elastomer, with an excess dimension. In this way, shape-fit and force-fit attachment of the bearing block within the side profile is brought about.
In an embodiment of the invention, alternatively or in addition, the clamping piece is also produced from an elastomer material. In this way, an improved clamping effect of the arms that are arranged opposite one another is achieved.
In a further embodiment of the invention, the clamping piece is pre-loaded in a pivoting direction by way of a spring element, preferably a torsion spring. In this way, constant contact of an arm on the door sash is brought about.
Other further developments and embodiments of the invention are indicated in the other dependent claims. Exemplary embodiments of the invention are shown in the drawings and will be described in detail below. The figures show:
The slide-and-swing sash system chosen as an exemplary embodiment consists essentially of a ceiling rail profile 1 and a floor rail profile 2, as well as a number of sashes 3, which are guided in the ceiling rail profile 1 by way of support parts 4 and in the floor rail profile 2 by way of guide carriages 34. On the end side, a side profile 5 is arranged between ceiling rail profile 1 and floor rail profile 2.
The ceiling rail profile 1 is configured essentially in the manner of a C profile. In the ceiling rail profile 1, guide grooves 11 are provided on its side walls, lying opposite one another, to hold the guide rollers 44 of the support parts 4 of the sashes 3. Below the guide grooves 11, an expansion clamp 12 is inserted into the ceiling rail profile 1 on the end side. Ahead of the expansion clamp 12, an outlet opening 13 is introduced into the ceiling rail profile 1, on the side, for releasing a support part 4 of a sash 3.
The expansion clamp 12 is configured as a pincer-shaped plastic part. In the arms of the expansion clamp 12 that are arranged opposite one another, arc-shaped formations are arranged, one after the other, which are provided, approximately in the center, with a groove for holding the guide plate 43 of a support part 4. The radius of the arc-shaped formations essentially corresponds to the radius of the guide rollers 44 of the support parts 4.
The floor rail profile 2 is configured essentially in C shape and has a longitudinal slot on its side that faces the ceiling rail profile 1, in which slot the guide carriage 34 of the sashes 3 is guided. On the side, an outlet opening 21 is introduced into the floor rail profile 2, lying opposite the outlet opening 13 of the ceiling profile 3, which opening is enclosed by a guide frame.
The sashes 3 are each formed by a pane element 31 that is enclosed, on the end sides, with frame profiles 32. The frame profile 32 of a sash 3 that faces the ceiling rail profile 1 has a formation 33 in the manner of a C profile, in each instance, to hold the groove plates 42 of the support parts 4. In the exemplary embodiment, each sash 3 is provided with two support parts 4, which are introduced into the C-profile-type formation 33 of a sash 3.
The support part 4 is essentially formed by a cylinder part 41, which is arranged on the end side with a groove plate 42 for engagement into the C-profile-type formation 33 of the frame profile 32 of a sash 3. The groove plate 42 is connected with the frame profile 32 of a sash 3 by means of screws. A guide plate 43 is formed on, lying opposite the groove plate 42, on which guide plate two guide rollers 44 are mounted on the cylinder part 41 so as to rotate, one on top of the other.
The outer sash that faces the side profile 5 takes on the function of a door panel 30. The pane element 31 of the door panel 30 is provided with an operating knob 301. A closure mechanism 6 is arranged on the side profile 5, by way of which mechanism the door panel 30 can be displaced in the direction of the adjacent sash 3.
The closure mechanism 6 comprises an operating lever 61 that is attached to the side profile 5 so as to rotate, which lever is connected with a thrust rod 62 mounted on the side profile 5 so as to be displaceable, in such a manner that a rotational movement of the operating lever brings about a vertical displacement of the thrust rod 62. On its end facing away from the operating lever 61, a slide pin 63 is arranged on the thrust rod 62, set at an angle to it, which pin engages into a channel 64 of a thrust piece 65. In the exemplary embodiment, the slide pin 63 has a rectangular cross-section, the outer mantle surface of which essentially corresponds to the inner mantle surface of the channel 64 of the thrust piece 65. In the exemplary embodiment, the slide pin 63 encloses an angle of 150° with the thrust rod 62 as well as an angle of 60° with the thrust piece 65. The channel 64 of the thrust piece 65 encloses the slide pin 63, lying against it, in such a manner that the slide pin 63 is compulsorily guided in the channel 64 of the thrust piece 65. The thrust piece 65 is attached to the cylinder part 41 of the support part 4 of the door panel 30 that faces it, as shown in
