Description

[0001] The invention relates to a fire protection and / or smoke protection sliding door according to the preamble of patent claim 1.

[0002] Single or, for example, double-leaf sliding doors are usually made of glass, which is usually framed with a surrounding door leaf profile, or at least with a profile in the closing direction and also in the opening direction.

[0003] When a single-leaf or multi-leaf door is closed, the door leaf profile facing the opening direction is adjacent to a wall-side profile, which is also referred to as the wall or reveal profile. The wall can be, for example, a building wall.

[0004] A corresponding profile structure is basically known from DE 44 17 583 C2.

[0005] In the case of the sliding door previously published above, the sliding door leaf is provided with a closing profile in the opening direction, which in horizontal cross-section projects beyond the rear door leaf boundary plane of the movable sliding door leaf in the direction of the adjacent wall or reveal, wherein the projecting section then runs onto a sealing profile when the leaf reaches the closed position, which is held on a section of the wall or so-called reveal profile projecting from the wall plane in the direction of the door leaf.

[0006] However, such or other sliding door structures are not suitable as fire and / or smoke protection sliding doors.

[0007] In the event of a fire, temperatures are so high that the sliding door leaves are subject to severe deformation. Depending on which side the fire originates, the highly uneven heating on both sides of the door causes extreme deformation, which could potentially cause fire and / or smoke to escape from the other side.

[0008] Publication DE 44 17 583 C2 generally describes a safety device for sliding doors in which both the sliding door leaf and the fixed leaf each have a closing profile. The individual profile legs do not interlock.

[0009] According to DE 20 2005 001 226 U1, a fire-resistant sliding door is described that comprises a door leaf profile with a freely ending profile leg arranged adjacent to a fixed reveal or wall profile. This reveal or wall profile also has another wall or reveal profile leg offset from the wall plane, which is oriented in the opposite direction to the previously described freely ending leaf profile leg. In the open position of the door, the respective free profile legs of the door leaf and the wall or reveal profile interlock in a virtually nested manner.

[0010] DE 297 15 667 U1 describes a fire door in the form of a swing door. The double-walled swing door has an opening at its rear into which a pin-shaped locking element protrudes when the door is closed. This locking element is attached and secured to the door jamb.

[0011] In the event of a fire, the door should bulge, causing jamming between the safety element and the swing door in the opening area in which the safety element engages the area of ​​the swing door.

[0012] The object of the present invention is therefore to create a fire protection and / or smoke protection sliding door with improved properties which can be closed as safely as possible, ie above all kept tight, even in the event of a fire and / or the escape of smoke.

[0013] The object is achieved according to the invention according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

[0014] Within the scope of the invention, a possibility is created using comparatively simple means to keep the deformation of the door as closed as possible, especially in the area of ​​the end edge of a leaf leading in the opening direction, so that deformations here cannot lead to the escape of fire and / or smoke on the other side.

[0015] The invention is based on the fact that, for example, either the door leaf has a profile leg which engages between two wall or reveal profile legs offset transversely to the door plane (sandwich-like) and / or conversely, a wall or reveal profile leg is provided which, in the closed position of the door leaf, engages between two door leaf profile legs offset transversely to the sliding door plane (sandwich-like).

[0016] According to the invention, the design is such that, during normal operation, the respective sliding door leaf can be easily adjusted to the open and closed positions without the respective profile legs hindering or impairing the closing movement. However, in the event of a fire, if the door leaf and profiles are severely warped, this leads to the force-locking of one of the sliding door profile legs with one of the two wall profile legs, or conversely, the at least one wall profile or reveal leg with at least one of the two sliding door profile legs, thus contributing to the desired high degree of closing security and tightness.

[0017] In the case described, there is therefore a force-locking tension in the event of a fire.

[0018] According to the invention, the respective profile legs are provided with projections, recesses, or cutouts that allow for alternating interlocking and / or engagement in the event of a fire. If the door deforms due to the high temperatures, this results in not only a force-locking but, above all, a positive interlocking between the interacting profile legs, thus achieving an even more secure closed position.

[0019] It has also proven advantageous if the wall or reveal profile comprises two profile legs spaced transversely to the door plane (or wall plane), each with corresponding projections and / or recesses formed or provided therein, between which a corresponding door leaf profile leg is located when the door leaf is closed. This door leaf profile leg is also provided with corresponding projections and / or recesses. Depending on which side of the door the fire occurs on, i.e. on which side the door bulges due to a "bimetallic" effect, the door profile leg interacts with the projections or recesses provided with the wall or reveal profile leg further away or closer to the door leaf.

[0020] Therefore, the advantages of the invention are realized regardless of whether a fire occurs on one or the opposite side of a sliding door, since regardless of the location of the fire, the deformation and bulging of the door leaf and also of the end profiles occur differently according to an occurring "bimetal" effect.

[0021] It has also proven advantageous if the interacting projections / recesses on the profile legs are provided several times at a distance from one another in the longitudinal direction (i.e. in the vertical direction), i.e. preferably do not have just one continuous projection and / or one recess running from bottom to top, etc.

[0022] The interlocking projections or recesses should be coordinated in terms of their shape and size. The design can be entirely different, e.g., in the form of bolts that engage in corresponding hole recesses, in the form of protruding noses that are more rectangular in vertical section and engage in corresponding slot recesses, etc. It is also possible for V-shaped projections to be formed in the profile legs in the same alignment, for example, in horizontal section. In each case, a V-shaped projection, for example on a wall profile leg, then engages into the rear V-shaped recess of an adjacent V-shaped projection upon appropriate deformation of the door profile leg, etc.

[0023] In brief, to connect a fire-resistant and / or smoke-resistant sliding door, or a combination of both, a first profile is provided and attached to a reveal or wall. This profile, together with another profile provided on the rear edge of the sliding door leaf, ensures and enables the lateral closure of the sliding door. When heated by a fire, thermal deformation creates at least a frictional connection and preferably a positive connection between the wall- and reveal-side profile and the door profile. This connection then absorbs the resulting forces.

[0024] This measure can ensure that no severe, unhindered deformations occur on the door leaf, so that no exit openings, slots or gaps are formed through which, for example, small flames can escape from a fire source to the other side of the door or even reach the demarcated space opposite the sliding door.

[0025] The invention is explained in more detail below with reference to the drawings, which show in detail: Fig. 1: a schematic front view of a double-leaf sliding door; Fig. 2: a horizontal section along the line II-II in Fig. 1 to illustrate the basic structure of a fire and / or smoke protection sliding door; Fig. 3: a fire and / or smoke protection sliding door according to the invention similar to Fig. 2; Fig. 4: a vertical section along the line IV-IV in Fig. 3; Fig. 5: a vertical section along the line VV in Fig. 3; Fig. 6: a view opposite to the opening direction of the door with the door profile bulged in the event of a fire; Fig. 7: one to Fig. 3 slightly modified embodiment in horizontal cross-section; Fig. 8: a partial perspective view of a part of the wall or reveal profile with the corresponding projections, according to the embodiment according to Fig. 7; Fig. 9: a schematic perspective view of the door profile with the corresponding door profile leg and the recesses made therein to achieve an interlocking with the projections according to Fig. 7 and Fig. 8; Fig. 10: a further modified schematic representation of a further embodiment in a schematic perspective view; and Fig. 11: one to Fig. 2 modified embodiment.

[0026] In Fig. Figure 1 shows a schematic front view of a sliding door with two sliding door leaves 1, which can open or close a passage in a wall 3 located behind the sliding door leaves 1. As is known, the sliding door leaves 1 are moved via carriages along a guide rail located above the sliding door leaf by means of an automatic sliding door control system. Reference is made to known sliding doors and sliding door drives in this regard.

[0027] The sliding door leaves 1 are typically provided with a circumferential profile 25, which is also referred to below as the leaf profile. The leaves themselves can be made of a suitable flat material, frequently glass. In particular, such glass sliding door leaves can also be provided with a frame, which is provided at least on the closing edge 7 leading in the closing direction and the opening, outer, or rear edge 9 leading in the opening direction.

[0028] In Fig. 2 is the basic structure of the fire and / or smoke protection sliding door in horizontal section along the section line II-II of Fig. 1 shown.

[0029] Adjacent to the passage 11, a wall 13 is shown, to which a wall or reveal profile 15 is usually fastened by means of several screws offset in the vertical direction.

[0030] In the illustrated embodiment, the wall or reveal profile 15 is U-shaped in horizontal section and has a first profile leg 15a, which is also referred to as the wall or mounting profile leg 15a, and a second profile leg 15b offset parallel to it in the direction of the sliding door leaf 1 and thus also parallel to the wall 13 or the wall surface 13'. Both profile legs 15a and 15b are connected to one another by a connecting leg 15c, resulting in an at least approximately U-shaped wall or reveal profile 15 in horizontal cross-section, which is preferably mounted on the wall 3 over the entire height of the leaf 1. The opening direction of the wall profile 15, which is U-shaped in horizontal cross-section, points away from the passage 11, thus pointing in the opening direction 21.

[0031] The sliding door leaf 1 has the already mentioned profile 25 in the opening direction 21, which is also sometimes referred to below as the leaf or end profile or end leaf profile 25.

[0032] The sash profile 25 is usually U-shaped and encompasses the sash material of the sash 1, usually the corresponding glass pane 23. The two corresponding sash profile legs 25a and 25b accommodate the edge of the door panel 25 (usually the glass pane 23) in between and are firmly connected to the sash material 23 directly or indirectly.

[0033] In the exemplary embodiment shown, the wing end profile 25 has a projection 27 projecting in the direction of the wall or reveal profile 15, with a further third wing profile leg 25c, which in the exemplary embodiment shown again runs parallel to the wing plane and ends freely opposite to the opening direction 21 of the door 1, wherein all three profile legs 25a, 25b and 25c are connected to one another via a connecting leg 25d.

[0034] The connecting leg 25d lies in the opening direction 21 of the sliding door leaf 1, so that a U-shaped receiving space 29 in horizontal cross-section is formed between the second and third profile legs 25b, 25c. In this receiving space 29 formed between the two profile legs 25b and 25c, which run parallel to each other in the illustrated embodiment, the second profile leg 15b of the wall or reveal profile 15, which ends freely in the opening direction 21 of the door 1, engages in the illustrated embodiment.

[0035] The alignment of the profile legs 25a, 25b and 25c as well as their position is such that the sliding door leaf 1 shown can be opened unhindered in the opening direction 21 and closed in the opposite direction again into its Fig. 1 and Fig. 2 shown closed position without the second profile leg 15b of the wall or reveal profile 15 colliding with the profile legs 15b, 15c of the sash profile 25.

[0036] To ensure a high level of tightness, either a first seal 31 and / or a second seal 32 can be provided, which is located at the bottom of the U-shaped receiving space 29 (i.e., on the inside of the connecting leg 25d) and / or inside the receiving space 17 formed by the two profile legs 15a, 15b, on the inside of the connecting leg 15c there. Thus, the free end of the profile leg 15b runs onto the seal 31 located in the receiving space 29 of the sash profile 25 and / or the free end of the profile leg 25c runs onto the seal 32 located in the receiving space 17 on the connecting leg 15c.

[0037] If a fire were to break out on the side of passage 11, the high heat generated on this side of the leaf would cause severe warping and deformation of the door, so that the free profile leg 25c would bulge significantly from top to bottom due to a "bimetallic" effect. As a result, this profile leg would become clamped to the two profile legs 15a and 15b of the wall or reveal profile 15, and the resulting high forces would lead to a frictional connection with the wall profile 15.This would limit the maximum bulging movement of the door profile and at the same time maintain a high level of tightness so that flames and / or smoke from the source of the fire cannot spread to the opposite side of the sliding door or escape (other measures to support tightness are provided in the upper area of ​​the sliding door leaves, which are not discussed in the context of the present application).

[0038] If a fire were to occur on the sliding door on the opposite side to the passage 11, the end profile on the door leaf 1 would bulge in the opposite direction from top to bottom, so that it would lead to a corresponding reversed tension between the free profile legs 25c and the two profile legs 15a and 15b of the wall profile 15.

[0039] It should be noted at this point that the individual profile legs do not have to run exactly parallel to the door leaf plane, but can be slightly inclined, at least in certain angular ranges, and / or can have material cross-sections that deviate from a rectangular cross-sectional shape.

[0040] An improved closing and sealing effect compared to the embodiment shown is achieved using an embodiment explained below.

[0041] The fire and / or smoke protection sliding door according to Fig. 3 to Fig. 6 is basically structured the same as that according to Fig. 2. In the case of the fire and / or smoke protection sliding door according to the invention Fig. 3 to Fig. 6, however, additional measures are provided, whereby not only a force-fitting but also a form-fitting connection between the door profile and the wall profile is realized.

[0042] For this purpose, the fire and / or smoke protection sliding door must be Fig. 3 on the inside of the profile leg 15a fastened to the wall 3 in the vertical extension direction of the wall profile 15, a plurality of projections 35 are provided at intervals from one another, for example in the form of bolts 35a, which extend at a certain height from the plane of the profile leg 15a in the horizontal direction.

[0043] Likewise, in the exemplary embodiment shown, a plurality of projections 37 are provided on the second profile leg 15b, also in the direction of extension of the profile leg, which projections 37 in the exemplary embodiment shown consist of bolts 37a, which may be of the same design and which also extend with a certain axial extension away from the plane of the second profile leg in the horizontal direction, wherein in the exemplary embodiment shown, the bolts 35a and 37a are each provided at the same vertical height and in axial extension to one another on the inner sides of the two opposite profile legs 15a and 15b of the wall or reveal profile 15.

[0044] During normal operation, the free leg 25c of the sash profile 25 engages in between without colliding with the projections 35 or 37, allowing the sliding door to be opened and closed unhindered. In the event of a fire, however, the aforementioned deformation of the sash profile occurs again, with a bulge acting vertically (i.e., transversely to the sash plane), with the result that the free profile leg 25c is now deformed in one direction or the opposite direction, depending on the location of the fire source.Since corresponding recesses and / or depressions, in the exemplary embodiment shown recesses 41, are provided in this free profile leg 25c, which are located at a corresponding height to the projections or bolts 35, 35a, 37, 37a and are at least slightly larger in diameter than the projections or bolts 35, 35a, 37, 37a, a deformation occurs so that, for example, in the upper and lower region of the wing profile 23, the bolts 35a penetrate into the recess 41 and in the middle height region of the wing profile 23, the opposite bolts 37 penetrate into the recess 41. One of the possible deformations is shown schematically in . Fig. 6 when viewed along the section VI-VI in Fig. 3, where Fig. 6 only the wall profile 13 with the profile legs 15a and 15b and with the projecting bolts 35a and 37a as well as the bulged position of the profile leg 25c is indicated.

[0045] For a better understanding, extracts are included in Fig. 4 a direct view, for example, of the profile leg 15a mounted on the wall 3 or the reveal 3 with the bolt-shaped projections 35, 35a, and in Fig. 5 a corresponding partial representation of the profile leg 25c which can be moved with the door, with the corresponding recesses or depressions 41 into which the projections 35, 37 can be inserted in the event of a fire.

[0046] If the fire source were on the opposite side of the sliding door, the bulge of the wing end profile 23 and thus also of the free wing profile leg 25c would be reversed to Fig. 6.

[0047] Due to the not only force-fitting, but also in the example shown form-fitting connection and in particular the interlocking between the wall and the door profile, the forces caused by the fire are optimally absorbed, and this without the need for additional special devices.

[0048] As already mentioned, the projections and recesses can be of various designs, with different sizes, cross-sectional shapes, and longitudinal extensions. The only important thing is that the corresponding projections and the corresponding recesses or depressions in the adjacent profile leg are coordinated in such a way that the desired form-fitting connection is achieved in the event of deformation caused by a fire.

[0049] Possible variants for different designs of the projections and recesses are shown using further examples.

[0050] In the embodiment according to Fig. 7 to Fig. 9, the projections 35, 37 are formed in the form of protruding noses 35b, 37b, which are more rectangular in vertical section or approximate this cross-sectional shape and extend along a certain vertical longitudinal direction. At a distance 40, a next projection 35, for example in the form of such a nose 35b, then follows in the vertical or longitudinal direction.

[0051] In this case too, the opposing projections 35, 35b projecting towards one another are again formed on the wall or reveal profile, wherein the projections in this embodiment are part of the profile legs 15a, 15b and can be produced by appropriate edging and folding of sufficiently dimensioned (or extruded) metal.

[0052] In this case too, the free-standing profile leg 25c belonging to the wing profile 25 is provided with corresponding, now elongated recesses 41, as shown schematically in extracts in the ordinary representation according to Fig. 9 are reproduced.

[0053] Based on Fig. 10 schematically shows a further spatial embodiment in which, for example, the projections and depressions are designed more V-shaped and can even point in the same direction and be designed with the same dimensions.

[0054] The V-shaped formations in horizontal section result in a projection 35 pointing in one direction and a V-shaped recess 41 formed thereby on the opposite side.

[0055] The variant is such that, upon appropriate deformation, the projection 35 provided on the free second leg 15b can engage or dip into the corresponding recess 41 on the free sash profile leg 25c, and that the V-shaped cross-section projection 41' on the free sash profile leg 25c, pointing toward the wall, can also engage the corresponding recess or recess 35 on the wall-side mounting profile leg 15a of the wall profile 15. For this purpose, this profile leg 15a is shaped with corresponding obliquely extending wall sections 15'a, forming the aforementioned recess 41.

[0056] Based on Fig.11 is intended to show only schematically, in deviation from the previous embodiments, that of course in principle corresponding projections (or depressions) can also be formed on the two opposite inner sides of the profile legs 25b and 25c of the sash profile, and that, for example, the free profile leg 15b of the wall or reveal profile 15, which dips into this receiving space 29, can be provided with the corresponding recesses 41.
