The invention further relates to a fire protection door or a door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extent, wherein in each case a first spring is arranged on the first end side and on the second end side, such in that the respective first spring engages in a first groove of a counter-configured door leaf element.

The invention also relates to a fire protection door or a door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extension, wherein in each case a first groove is arranged on the first end side and on the second end side, in such a way in that a first spring of a door leaf element designed in the same way engages in the respective first groove.

From the FR 2 593 221 goes out a horizontally movable formed of several door leaf elements gate. The door leaf elements have a first and a second end side along their longitudinal extent, wherein a first tongue and a second groove and the second end face a first groove and a second spring are arranged on the first end side.

The first spring engages in the first groove and the second spring engages in the second groove of an equivalent door leaf element. The door leaf elements are pivotally connected to each other via hinges.

From the DE 196 42 734 A1 is a closure device for closing door or door openings and window openings or furniture openings out. The closure device has two opposing blades, which are connected to each other via a hinge. Each of the lamellae has a first end side and a second end side along its longitudinal extent, wherein a first spring is arranged on the first end side and a first groove on the second end side. The first spring engages in the first groove. At the base of the first groove another spring is disposed and on the end face of the first spring, a further groove is introduced, wherein the further spring engages in the further groove.

From the US 5,737,802 A1 goes out a sectional door, which has a plurality of door leaf elements. The door leaf elements are medium along their longitudinal extent at the end faces a rotary joint interconnected. The hinge has a first element and a second element. The first element has a first groove, wherein a further spring is arranged on the base surface of the first groove. The second element has a first spring and an additional groove formed on the end face of the first spring. Here, the first spring engages in the first groove and the other spring in the further groove.

The above-mentioned gates or doors are primarily sectional doors or sectional doors comprising a plurality of panels, wherein the panels are pivotally connected to one another via hinges or hinges. However, such sectional doors or sectional doors are not suitable to be used as fire protection sliding doors, as they do not withstand unilateral fire exposure for a long period of time, have insufficient gas tightness and also have a thermal bridge.

There are already known fire doors, which are composed of several door leaf elements. The individual door leaf elements are connected to each other via tongue and groove connections to a gate or a door. In this case, each door leaf element can be constructed identically and therefore have a spring on a first side and a groove on a second side. However, it is also possible for door leaf elements to be lined up alternately, with each second having a tongue on both sides and a second tongue having a groove on both sides.

Such a built fire protection sliding door is for example from the German utility model DE 86 05 369.2 U known. In it, the individual door leaf elements are formed from a thermally insulating material and are encased by a sheet metal shell. At the joints a tongue and groove connection is formed, so that the individual door leaf elements can be connected to a gate or a door connected in series. Each shock is provided on both sides of the door leaf with a heat-insulating strip, which is firmly connected to each of the groove having door leaf element.

A disadvantage of this known design is that the joints represent a weak point for fire protection, since they are insufficiently tight for gases and liquids and also represent a thermal bridge. Thus, in a fire, heat is conducted via the joints from one side of the fire door to the other side. This effect is only insufficiently mitigated by the thermal insulation strips. These strips also provide a additional installation effort and complicate a recessed installation of the fire door.

It is therefore an object of the present invention to develop a fire door or a door such that the shock between each two door leaf elements can be made tight without additional installation and manufacturing effort and he also does not represent a thermal bridge.

This object is achieved by a fire protection door or door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extent, wherein a first spring on the first end side and a first groove on the second end side is arranged wherein the first spring of a first door leaf element engages in the first groove of a similar second door leaf element, wherein on the base surface of the first groove another spring is arranged, wherein on the end face of the first spring, a further groove is arranged, wherein the further spring of the first Door leaf element engages in the further groove of the similar second door leaf element, and wherein the cross section of the first spring and / or the second spring in a wedge shape to the respective end face, or the cross section of the first groove and / or the other groove wedge-shaped to the respective base out rejuvenates that same like door leaf elements are held together by a wedge effect.

This object is achieved by a fire protection door or door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal extent, wherein on the first end side and on the second end side in each case a first spring is arranged, wherein the respective first spring of a first door leaf element engages in a first groove of a counter-configured second door leaf element, wherein in each case a further groove is disposed on the respective end face of the first springs, wherein in the respective further groove of the first door leaf element another spring of the counter-configured second door leaf element engages, and wherein the cross section of the first spring and / or the second spring wedge-shaped to the respective end face, or the cross section of the first groove and / or the further groove wedge-shaped tapered towards the respective base surface such that the gegengleich ausgestal Teten door leaf elements are held together by the wedge effect.

This object is achieved by a fire protection door or door constructed of two or more door leaf elements, which are provided with a first end side and a second end side along its longitudinal direction, wherein on the first end side and on the second In each case a first groove is arranged, wherein in the respective first groove of a first door leaf element engages a first spring of a counter-configured second door leaf element, wherein on the respective base of the first grooves each have a further spring is arranged, wherein the respective further spring of the first door leaf element engages in a further groove of the counter-configured second door leaf element, and wherein the cross section of the first spring and / or the second spring in a wedge shape to the respective end face, or the cross section of the first groove and / or the other groove wedge-shaped to the respective base out tapers that the counter-designed door leaf elements are held together by the wedge effect.

This configuration of the tongue and groove connection has the advantage that when nesting two adjacent door leaf elements results in a labyrinth-like seal, which is a major obstacle to the passage of gases and heat. Since the shock itself is already dense and insulating, can be dispensed with additional heat insulation strips. This results in a particularly simple construction of a fire door with a substantially smooth, flat surface. Such a gate or door can be installed as a sliding door or sliding completely sunk in a wall opening. The door leaf elements can be easily assembled via the tongue and groove joints. It can be formed with several standard door leaf elements gates and doors of any width. Due to the wedge effect a particularly good seal is achieved when pushing together two door leaf elements.

In this context, it can be provided that at least one of the side surfaces of the first spring and / or the side surfaces of the further spring, and one of the side surfaces of the first groove and / or the side surfaces of the further groove at a first angle obliquely to the longitudinal center plane of the door leaf element. By forming a wedge sealing is ensured by the fact that when pushing together two door leaf elements, the side surfaces of each mutually associated groove and spring accumulate against each other and rest under pressure against each other.

In a further embodiment of the invention, the first angle between 0.1 ° and 15 °, preferably between 0.5 and 10 °, preferably between 1 ° and 5 °, more preferably between 1.5 ° and 2.5 °, in particular 2 °. With an angle of the specified size, a particularly good seal can be achieved, while in the assembly of the individual door leaf elements no excessively increased effort is needed In an advantageous manner, the outer contour can be formed, at least in some areas, from one or more composite, preferably two mirror-inverted, sheet metal shells. The sheet metal shells have a good fire protection and are also easy to manufacture.

In a particularly advantageous manner, it can be provided that the sheet metal shells do not extend over the entire thickness of the door leaf element, so that in each case a first sheet metal shell is arranged on a first side surface of the door leaf element and a second sheet metal shell on a second side surface of the door leaf element and the sheet metal shells do not touch. As a result, heat conduction from one side of the door leaf element to the other can be effectively prevented.

In this context, the interior of the door leaf element may be formed by a, preferably one-piece, packing. This results in an improved fire protection through the sandwich-like structure, wherein the door leaf element is bounded from the outside of the sheet metal shells.

In a further embodiment, the filler may consist of a thermally insulating material. As a result, the heat conduction from one side to the other can be further reduced.

In Weitelführung of the invention, the outer edge of the first end face and / or the second end face be chamfered, preferably such that substantially the entire Front side outside the first groove or outside the first spring at a second angle obliquely to the longitudinal center plane of the door leaf element.

In this context, the second angle between 10 ° and 80 °, preferably, between 30 ° and 60 °, preferably between 40 ° and 50 °, more preferably between 43 ° and 47 °, in particular 45 °.

According to a variant, a recess may be provided on the underside of the door leaf element, which can accommodate a bottom mounted guide roller when using a constructed of a plurality of door leaf elements door or a door. In this way, the door or the door can also be guided on the underside and thus also withstands loads resulting from pressure differences between the two sides of the door or the door.

In this case, at least one lateral guide surface can be provided in the recess. As a result, the lateral guide can have less frictional resistance and ensure particularly precise guidance.

A further variant of the invention may provide that at the upper end of the door leaf element, a chassis is arranged, which chassis consists of at least two support rollers which are arranged rotatably about the same axis or about mutually parallel axes, wherein at least a first of the support rollers on a first side of the longitudinal center plane of the door leaf element and at least a second of the support rollers is arranged on a second side of the longitudinal center plane of the door leaf element. Through this support rollers, a gate or a door from inventively designed door leaf elements may be suspended on its upper side, wherein the door or door hangs freely on the support rollers without lateral forces. In this way it is ensured that the door can move freely and without much resistance from an open to a closed position.

In this context, it may be provided that the first support roller has a profile which can transmit axial forces, so that the position of the first support roller is fixed in the direction of the axis, while the second support roller has a profile which can not transmit axial forces, so a shift of the second support roller in the direction of the axis is possible. This makes it possible to set the position of the door or the door in a direction transverse to the center longitudinal plane exactly, but without running the risk that deteriorate the rolling properties. Such a chassis guarantees easy mobility despite a precise positioning, which properties for a secure closing and a good seal are necessary.

According to a development, the first support roller may have a substantially V-shaped or U-shaped, preferably inwardly curved, profile. In this way, a precise lateral positioning of the door leaf element is possible in a simple manner.

Again, according to a development, the second support roller may have a substantially planar or outwardly curved profile. This ensures that no lateral forces are transmitted to the second support roller and thereby it can not lead to jamming of the door or the door.

Advantageously, a shaped body can be arranged on at least one front side of a door leaf element, which engages in a groove on said end face and complements the outer contour of the door leaf element such that a flush or closed surface is formed. In this way, despite the presence of an end-side groove, a flush completion of the door or the door is given. Since this shaped body complements the profile, there is a massive conclusion of the door or the door, which opposes a high resistance from outside. Standard door leaf elements can also be used as the ultimate element. Advantageously, the shaped body can be held by a sheet-metal profile, preferably a C-profile. This results in a particularly massive conclusion, which ensures the same good properties in terms of fire protection and resistance as on the side surfaces of the door leaf element on the front page.

It is also disadvantageous in the fire protection gates which have become known from the prior art that the impact between the lateral edges of the door and the reveal of the wall opening constitutes a weak point for fire protection, since the collision for gases and liquids is only insufficiently tight.

Advantageously, at least one edge of the fire door or the door, preferably on at least one outermost door leaf element, a unilaterally projecting profile is arranged, which has a free end in the closing direction of the door or the door, which in a gegengleich shaped free end of frame-mounted profile can engage, so that there is a labyrinthine seal with the door closed or door closed. The free end of the one-sided projecting profile, together with a frame-mounted profile results in a further sealing of the door or the door to the soffit of the wall opening. As a result, this vulnerability is sealed and there is a particularly good fire protection.

In this context, may be arranged on the inside of the one-sided projecting profile, a shaped body which engages in a groove on an end face of a door leaf element. In this way, despite the presence of an end-side groove, a flush completion of the door or the door is given. Since this shaped body complements the profile, there is a massive conclusion of the door or the door, which opposes a high resistance from outside.

According to an advantageous embodiment, a conclusion may be provided on the non-protruding end of the one-sided projecting profile, which complements the outer contour of a door leaf element such that from the one-sided projecting profile and the outer contour of the door leaf element, a flush or closed surface is formed. As a result, the profile of the door leaf element is supplemented to a full rectangle, which results in spite of the presence of a frontal bevel no weakening of the door or door thickness. Thus, an inventive gate or door can be used universally and yet be constructed from a variety of similar door leaf elements. Also, each last door leaf element can therefore have the same structure as the other door leaf elements.

According to a further development, an intumescent material, in particular a material that swells and / or foams under the action of heat, can be arranged in a fire protection door or a door between two adjacent door leaf elements, preferably in the element impact. As a result, even better sealing of the labyrinth joint in case of fire can be achieved.

With reference to the figures, numerous aspects of a fire door will be explained in more detail by way of example in the following. The fire protection door shown consists of several individual door leaf elements 40, 50, 60, etc., which lined up form a gate or door leaf. As a result, the terms "gate" and "door" should not be further differentiated. Rather, it should be clear that the statements made for a goal apply equally to a door.

Each door leaf element has a core 15 of heat-insulating material, which is enveloped by a metal jacket. Like from the FIGS. 2a to 2c As can be seen, the metal jacket is formed from a first sheet metal shell 31 and a second sheet metal shell 32. The two sheet metal shells 31 and 32 surround the core 15 only in partial areas, in a partial area near the longitudinal center plane L, the core 15 is not covered by any sheet metal shell. However, this part is located after the joining of several door leaf elements inside the gate, so that on the outside still creates a closed metal jacket. The sheath-free zone, however, effectively prevents the formation of a thermal bridge from one side of the gate to the other.

Like in the FIG. 1b an intumescent material may be applied between the elements, ie in the element joint, to provide an even greater barrier to the passage of gases and heat. This material foams under the influence of temperature and / or increases its volume, whereby an even better sealing of the labyrinth joint in the element impact can be achieved.

According to a first variant as in FIG. 2a On the door leaf element on one side a first spring 3 and on a second side a first groove 4 are formed. At the in FIG. 2a Left first end face 1 of a door leaf element shown a first spring 3 is arranged. On the right illustrated second end face 2 of the door leaf element, a first groove 4 is formed. At the end face 12 of the first spring 3, a further groove 7 is formed. At the base 5 of the first groove 4, a further spring 6 is arranged. The springs and grooves are matched to one another such that the profile of a first end face 1 can be inserted into the profile of a second end face 2 of a similarly constructed door leaf element. The profiles of grooves and springs complement each other in such a way that over the cross section of the door results in a shock with a zigzag course. This zigzag course ensures an improved sealing effect of the labyrinth seal formed thereby.

According to another variant as in FIG. 2b is formed on the door leaf element on both sides of a first groove 4. This can be joined together with a counterpart, that is to say with a first spring 3 formed on both end faces. Such opposite leaf door element is in Figure 2c shown. When merging the elements after FIGS. 2b and 2c The result is the same impact with a zigzag course as when joining several elements as in FIG. 2a ,

The exact course of the frontal, formed from a sheet metal shell 31 is in the FIGS. 3 and 4 shown. In this case, on the left side shown on the left side 1 is the outer Side surface 8 of the first spring 3 with respect to the longitudinal center plane L at a first angle α obliquely. Likewise, at the second end face 2 shown on the right, the inner side surface 9 of the first groove 4 is inclined relative to the longitudinal center plane L at precisely this first angle α. The first angle α drawn in the exemplary embodiment is approximately 2 °, but it may also have other suitable values. However, it should be ensured that the individual door leaf elements are held together by the wedge effect. Alternatively or additionally, the inner side surface 11 of the further groove 7, which is arranged on the end face 12 of the first spring 3, could be designed obliquely with respect to the longitudinal center plane. In this case, the outer side surface 10 of the further spring 6, which is arranged on the base surface 5 of the first groove 4, would be executed obliquely with respect to the longitudinal center plane L.

The first end face 1 and the second end face 2 extend at a second angle β obliquely with respect to the longitudinal center plane L of the door leaf element. This results in an assembly of the individual door leaf elements at each impact a V-shaped recess.

In the FIG. 5a is a frontal conclusion of a fire door with a one-sided projecting profile 16 shown. In this case, on the side of the first spring 3 in the further groove 7, a closure profile with a molded body 20 is inserted. The shaped body 20 has a shape corresponding to the inner contour of the further groove 7, so that it is securely held in the further groove 7. The unilaterally projecting profile 16 is angled at its projecting free end 17 in the closing direction of the door. Therefore, when closing the door, it is possible for a frame-mounted, oppositely shaped profile 19 to engage behind its free end 18 and thus produce a labyrinth-like seal. At its non-protruding other end, the profile 16 on a conclusion 21. This conclusion 21 completes the outer contour of the outermost door leaf element to a full rectangle, so that there is a flush surface. As a result, even the outermost door leaf element can be constructed the same as all other door leaf elements and it still results in a clean conclusion, without that on the front side 12 of the outermost door leaf element an outwardly open groove or a protruding spring would be visible.

In the FIG. 5b is a frontal conclusion of a fire door with a shaped body 33 is shown. The molded body 33 may be surrounded with a metal jacket in the form of a front C-profile 35 and may be inserted into the first groove 4. The molded body 33 thus forms a conclusion and complements the outer contour of the outermost door leaf element to a full cross-section, resulting in a flush or closed surface. As a result, even the outermost door leaf element on the inlet side of the door leaf can be constructed the same as the other door leaf elements and it still results in a clean conclusion, without that on the front side of the outermost door leaf element an outwardly open groove or a protruding spring would be visible.

As in the FIGS. 6 and 7 shown, a landing gear is arranged on the top of a door or a door leaf element. At this, the gate or the door leaf element along rails 27 and 28 are moved. The running gear consists of at least one support roller 21 on a first side of the longitudinal center plane L of the door leaf element and a second support roller 22 on a second side of the longitudinal center plane L of the door leaf element.

The first support roller 21 has a profile which can transmit axial forces. In the illustrated embodiment, this is a V-shaped inwardly curved profile. Alternatively, however, any other shape would be possible that can transmit axial forces, such as a U-shaped profile or an outwardly curved profile, which could then cooperate with a recess in an inwardly curved track rail. In the example shown, the axial position of the first support roller and thus of the chassis and the door leaf element is determined together with the outwardly curved first rail 27. The arranged on the opposite side of the longitudinal center plane L support roller 22 has a profile which can not transmit axial forces. In the example shown, it is a flat profile. Alternatively, but here, for example, an outwardly curved profile conceivable. The profile cooperates with the second running rail 28 in such a way that no axial forces can be transmitted. The axial location of the second support roller 22 and thus of the chassis and the door leaf element is done exclusively on the first support roller 21 and the first track rail 27. In this way and

Way, it is possible to determine the exact axial position of the chassis while ensuring a good mobility. Jamming or tilting is effectively avoided.

With reference to FIG. 7 Now, the provided on the underside of a door leaf element guide is described. For this purpose, a recess 24 is provided in the door leaf element, in which a guide roller 29 arranged on the bottom side engages. The guide roller 29 contacts the door leaf element at one or two opposite Guide surfaces 25. By providing a guide in the lower end region of the door leaf element this is also held on the underside. As a result, it not only hangs down freely from the carrying rollers, but is also accurately positioned on the underside in a direction normal to the central longitudinal plane. Such a suspended and guided gate can therefore close a wall opening more accurate and better and thus ensure improved fire protection.

The FIGS. 8 and 9 show further possible embodiments of the cross section of the track profile 26, in particular the track rail 28th

In the FIGS. 10 and 11 Further versions of trolleys with idlers 21 and 22 are shown. In the variant according to FIG. 10 the heat-insulating material 15 extends substantially over the entire height of the fire door, ie also up on the chassis up. In the variant according to FIG. 11 ends the heat-insulating material 15 just below the axis 23 of the chassis. The latter is therefore placed in this embodiment, the heat-insulating material 15.
