TECHNOLOGICAL BACKGROUND

A folding gate is described for example in DE 2 001 349 A1. The gate shown there comprises an upper, d. H. lintel, gate and a lower, d. H. bottom side, gate leaf. In the closed position, both leaves are arranged in one plane. Both wings are connected to each other with a horizontally oriented pivot. At the upper gate a drive means is arranged, which comprises a drive shaft, and with which a fixed to the lower gate pull rope on a drum and is unwound. The lower door leaf is thereby pivoted relative to the upper door leaf around the axis of rotation arranged between the door leaves. At the same time, the upper leaf pivots upwards around a pivot axis in the region of the lintel. In the open position, the leaves are in a V-shaped position. To open a drive device pulls the lower door leaf via a pull cable upwards. The motor of the drive device is arranged according to DE 2 001 349 A1 on the upper door leaf. A locking of such gates, such as to prevent unwanted opening, is done regularly in that in the region of the rotary joint between the wings a arranged on one of the leaf safety clip is operated, which interacts with the other leaf, and by - starting from the closed door position - A movement of the one wing is blocked relative to the second wing.

Especially with very wide lifting folding doors, such as a bifold (hangar) gate, it is necessary to raise / lower comparatively large forces due to its own weight. te / moments. If the engine - as described in DE 2 001 349 A1 - is attached to the gate, this effort is increased by the effort to lift the engine. In the case of very wide doors, a considerable effort for lifting the door or braking during lowering of the door can thus be required. In addition, it may come at wide gates to sag the raised gate. The deflection may be due to the drive motor attached to the gate or due to the dead weight of the material from which the gate leaves are formed. If additional force is applied to the door, such as wind or force, the locking mechanism in the area of the swivel joint may fail. This is where the invention starts.

PRESENTATION OF THE INVENTION

The invention has for its object to improve the handling and securing of Hebefaltystemen, in particular lifting folding doors. This object is achieved by a Hefeating system (Hebefalttor, Hebefaltladen) according to claim 1. Embodiments of the invention Hebefaltsystems / Hebefalttors result from the dependent claims. Hereinafter, the term siphon gate is used regularly, and the described may also refer to features of the Hebefaltystems. In the lifting folding gate according to claim 1, it is accordingly provided that the locking device can be locked or unlocked via the drive device, in particular via a locking driver connected to the drive device. The unlocking of the locking device is carried out before lifting the Hebefalttors. The locking of the locking device takes place after lowering the Hebefalttors. It is provided that the locking device comprises at least one, in particular formed as a bolt or claw or hook or pliers, locking element which interacts mechanically with a arranged in and / or on the floor locking receptacle. By the interaction of the locking device with the example in the center of the wing respectively center (ie between the side frame members) arranged on or in the bottom locking receptacle an (additional) lock is provided which prevents the gate or one of the gate or the Hebefaltladen by wind power or external (force) action is movable or bendable, especially in the area of the locking receptacle. It is also possible to provide a plurality of locking receptacles with which a respective locking element interacts, so that the locking device comprises a plurality of locking elements. The interaction of the locking element with the locking receptacle takes place preferably when respectively for locking. When or for unlocking the locking element is moved out of the locking receptacle or dissolved out. If the locking element is formed, for example, as a claw, the interaction is that the claw about a rod or a resistance element engages behind for locking. To unlock the claw is rotated or adjusted, so that there is no mechanical interaction between the locking element and locking receptacle.

The handling and securing of Hebefaltsystemen as Hebefalttoren we further improved by a Hebefaltsystem according to claim 2. Accordingly, it is provided that the locking device via the drive device, in particular via a locking device connected to the drive device, lockable or unlocked, wherein the unlocking of the locking device takes place before lifting the Hebefaltsystems, and wherein the locking of the locking device takes place after lowering the Hebefaltsystems , The locking device comprises at least one, in particular formed as a bolt, locking element, which mechanically interacts with a arranged in and / or on a frame side part locking receptacle for locking. The lateral (additional) locking prevents unwanted opening of the door in the area of one or both frame side parts. The frame and / or the frame side parts may be (immovable) part of the lifting system. According to one embodiment, a plurality of locking elements and correspondingly a plurality of locking receptacles may be provided per frame side part, for example, an (additional) locking may be provided for each wing on each of the sides.

The side lock may also be arranged in the frame, for instance in the frame side parts. In this case, locking drivers are guided in or on the frame. Locking bolts of this variant engage for locking in recesses or openings which are arranged in the lifting folding system, for example in the bottom wing and / or the sash. Locking hook this variant of the side lock can engage behind, for example, rods or projections in or on the wings. Preferably, at least one opening (receptacle) is arranged on the bottom side or near the bottom, resulting in a lateral and ground-level locking. It can also be a combination of one on the wing (pair) arranged and arranged in / on the frame Seitenver-locking be provided. According to one embodiment of the lifting fold system, it can be provided that the locking device comprises a plurality of locking elements, wherein at least one (first) locking element interacts with a locking receptacle arranged on the bottom side, ie with a locking receptacle arranged in and / or on the floor, and wherein at least one second) locking element interacts with a laterally acting locking receptacle, ie with a arranged in and / or on a frame side part locking receptacle or with at least one arranged in or on the frame locking element. Accordingly, the gate is locked at the bottom and side. If the system is formed as a store, the bottom-side locking receptacle is arranged in the region of the window underside or the window sill.

In all embodiments of the locking device is in the locked state of the door or loading an unintentional moving, d. H. An unintentional lifting / pivoting of the door / store or at least one wing prevents, at least considerably more difficult. In particular, by the interaction of the components locking element and locking receptacle, the gate or the store against unwanted opening safer. For example, opening the gate (loading) of unauthorized persons is considerably more difficult.

As a tension element, a rope, a belt, a toothed belt and / or a chain can be provided. The guiding respectively winding and / or unwinding of a tension element can take place by means of a, in particular toothed, roller or drum. There may be provided a chain drive for raising / lowering the system. Pull and / or drive elements can be arranged in the frame, in particular guided. The frame may include a frame.

According to one embodiment of the lifting fold system, it can be provided that the locking receptacle is formed as a pocket for a bolt, or as a pocket with a rod for grasping a claw, a hook or for gripping by a pair of pliers. The pocket can be formed as a recess, release or depression in the bottom region or in the region of the lower edge of the window. The geometry of the pocket can be adapted to the dimensions of the locking element, such as the dimensions of the bolt so that the locking element or the bolt with some play in the pocket is inserted. According to a further variant of the door, the locking device may comprise a surface lock, in particular a central locking. The surface lock can be actuated via a surface lock driver. It is suitable for locking the position of the bottom wing and / or the sash in the closed position, in particular in the area of the wing pivot joint. For example, the Torflächenverriegelung include bolts which laterally engage in suitable receptacles which are arranged in the frame or in the frame side parts. The locking driver of the locking device may comprise a cable, a Bowden cable or a driver linkage. Conveniently, the locking driver on the gate, that is arranged on one or both leafs. Alternatively, arranging the locking driver in or on the frame may be provided.

It is expedient if the actuation of the locking device takes place during the free running of the drive device, in particular before the lifting or after the lowering of the lifting fold system. Freewheel includes the rotation of the drive shaft or movement of drive components, in which there is no gate or loading movement, as pulling or lifting devices, ropes, chains, belts, hydraulic equipment or similar acting components not yet (lifting) or not (Absen ken). When the liftgate is lifted, it does so during the first revolution (s) of the drive shaft before the gate is moved. The shaft rotates, thereby activating the driver or the driver of the locking device, and only then are the tensile elements subjected to forces and the gate is raised. When lowering, the order is reversed: The gate is moved to the closed position, the drive shaft rotates a little further, while the drivers for the locking device are actuated.

An improvement in the handling and securing of lifting-folding systems also results from a lifting-folding system according to claim 7, in which an additional pulling element is provided which mechanically supports the pulling element. The additional traction element can be arranged, for example, between the frame side parts, approximately in the middle between the frame side parts. The additional traction element may comprise a locking driver for actuating the locking device or may be formed from a locking driver. It can also be the cable of a locking driver used as additional traction element. The embodiments of the lifting fold system described here can each comprise a deflection system which is suitable for deflecting the tension element and / or the or an additional tension element. The redirecting system may be associated with a locking driver. By the deflection system, the direction of action of a tension element and / or a driver and / or a Zusatzzugelements is changed. If the tension element is formed as a rope, the deflection system may comprise, for example, one or more deflection rollers. The deflection system or a deflection roller can be arranged on the gate, ie on one or both leafs. It can also be provided that the deflection system, at least in sections or in part, or a deflection roller on the frame (side part) is arranged.

It can be provided that the actuation of the locking device, in particular of the or a locking element, takes place against the action of a restoring force, in particular against the action of a spring. In conjunction with the deflection system is achieved so that a locking element without its operation is in the locked position, d. H. in a position where the element protrudes beyond at least one of the edges of the door. Actuation is by pulling forces, which are oriented by pulleys on the gate / loading so that the locking element is moved towards the goal, d. H. so that it no longer protrudes beyond the gate. This is done against the action of a restoring force of a spring. The stopping of these tensile forces causes the spring forces to act and the locking element gets into the locking position. The spring may be formed as a tension spring, such as for the return of a locking bolt, or as a torsion spring mechanism for the return of a hook or a claw or the like. If the locking device (at least predominantly) is arranged in or on the frame, it can be provided that the locking element (or bolts) against the action of a spring in the recess in the gate / shop access, and that to unlock by means of driver assembly, the force of restoring spring would be overcome.

The drive console can alternatively be arranged laterally, for example on the frame or next to the frame, in particular on a frame side part. This is particularly useful for gates whose gate width is less than about 6m. On the drive console one or the drive shaft is rotatably mounted. The drive console may be formed as a center console or side panel. On the console, the drive motor of the drive can be arranged. The console, in particular the center console, may be mounted on the lintel of the building opening. If the drive shaft is formed in several parts, can be provided per Hebefalt- system several consoles, such as one or more side panels or a center and at least one side panel.

A guide element, in particular a roller or drum, may be arranged on the drive console, for example a tension element guide means and / or driver guidance means for guiding an (additional) tension element and / or the locking driver. The guide element is mechanically coupled to the drive shaft. The torque is transmitted from the drive shaft to the rotatably connected to the drive shaft roller / drum and from there - via a guide element - on the tension element and / or the driver.

According to a preferred embodiment of the present invention described Hebefaltsystemausführungen at least one, in particular in or on the frame out, weight-compensating means may be provided. The weight balance achieved thereby relieves the drive device and / or the drive console. The weight balance can be achieved by one or more counterweights, which are arranged for example on at least one pull rope or on at least one chain or on a toothed belt. If the weight of the counterweights almost equal to the weight of the door leaf (dead weight of the system), the goal or the shop can be raised or lowered with very little effort.

To secure the gate / store against uncontrolled falling down a fall-arresting means may be provided. The fall-arresting means may comprise an (emergency) brake, which engages approximately in the drive movement and / or in the movement of the Hebefaltsystems when one of the involved components, such as a tension element, such as by breakage or crack fails. An improvement in the handling and securing of lifting-folding systems also results from a drive device according to claim 16. The drive device is particularly suitable for a lifting-folding system described here. The drive device comprises at least one drive console mountable on a building wall, in particular on a fall of a building opening in a building wall or on a frame or on a console. In the drive console at least one drive shaft or at least a portion of a multi-part drive shaft is rotatably mounted. It can also be provided several waves, wherein the axis of rotation of the waves can be parallel to the fall or perpendicular to the fall. On the shaft or on one of the waves, a rope can be wound up. It can be provided on the shaft arranged drum, in particular for winding / unwinding of a pull rope or a driver cable. The drive console comprises at least one guide element attached to the drive shaft, such as a drive guide means for guiding a driver or a driver component for actuating a locking and / or pulling device of the lifting fold system.

An improvement in the handling and securing of lifting folding systems also results from a frame for mounting a lifting folding gate according to claim 17. The frame is particularly suitable for a lifting folding system described herein. The frame may be formed as a guide rail for components of the Hebefaltsystems or at least comprise a guide rail. The guide rail can be mounted on the building wall. The (gate) frame includes laterally in or on a building opening anordbare frame side panels.

DETAILED DESCRIPTION OF EMBODIMENTS

A frontal view of a siphon gate 1 can be seen in FIG. The lift gate forms a lift system for a door opening, ie for a building opening on the ground. The features shown in FIGS. 1 to 11 can also be realized in a lifting folding store not made here. The sash folding door 1 according to the figures is referred to below as "gate." The door 1 is shown in the closed position of the door according to Fig. 1. The gate 1 comprises two sashes 2, 3, namely a slung side (upper) Lintel door 2 and a bottom (bottom) Bodentorflügel 3. The two leaves 2, 3 of the gate 1 are located in the gate position shown in Fig. 1 in the goal plane, which lies in FIG. 1 in the plane. The leaves 2, 3 are connected to each other via a wing pivot 6.

The gate 1 is mounted in an opening of a building wall 4. Above the gate 1 is the lintel 5. The pair of wings (2, 3) is arranged in a door frame 7. The frame 7 comprises two frame side parts 8. Below the bottom-side Bodentorflügels 3, the bottom 9 is shown.

A side view of a door 1 in the open position can be seen in FIG. 2 (sectional view). About traction elements 10, the bottom-side Bodentorflügel 3 was pulled in a guide upwards. The door 1 is thereby "folded", that is, the wings 2, 3 rotate about the axis of rotation of the wing pivot joint 6 and form in the open position a (according to FIG. 2 lying "" V "). When closing, the angle of the "V" becomes larger until both legs of the "V", as can be seen in Fig. 3, are arranged in a plane.

A side view of the door 1 in the closed position can be seen in Fig. 3 (sectional view). The goal plane extends according to FIG. 3 perpendicular to the plane of the drawing. In the area of the camber 5 a crash joint 41 is arranged. The lintel door 2 is rotatably attached to the lintel 5 with the lintel 41. When opening (lifting) and closing (lowering) of the gate 1, therefore, the joints 6 (wing swivel joint) and 41 (crash joint) are operated. A sectional view from the top of the gate 1 according to FIG. 1, the Fig. 4. Accordingly, the frame side parts 8 are arranged in recesses 11 of the wall 4. In the frame side parts 8 run toothed belt 12 to which weights 13 are attached. The weights 13 generate a weight balance of the dead weight of the door 1. Almost over the entire width of the door 1 extends the drive shaft 15. The drive shaft 15 is mechanically connected to the drive motor 18. The drive motor 18 is fixed (by means of the drive bracket 16) to the wall 4 and rotates the shaft 15 for lifting the door 1 in one direction of rotation and for lowering the door 1 in the other, opposite direction of rotation. Between the motor 18 and the shaft 15, a transmission may be provided. Torsionally connected to the drive shaft 15 are tension elements 10, with which in particular the bottom door leaves 3 can be pulled upwards. For lifting the tension elements (10, 12) approximately via a toothing, preferably in the frame side parts 8, out. An enlarged detail view of a frame side part 8 (shown in FIG. 4 on the right) can be taken from FIG. 5. There it can be seen that each toothed belt 12 runs over a toothed wheel 14, which is connected in a rotationally fixed manner to the drive shaft 15. Timing belts are suitable for transmitting forces in both rotational directions of the rotary shaft, which is expedient in the case of a weight-balanced door 1.

FIG. 6 shows a detail of the plan view according to FIG. 4. There, the drive console 16 is illustrated, in which at least one drum 17 for guiding / winding a cable pull of a locking driver 19 is arranged. The locking driver 19 comprises the (wire) cable with which the locking element 20 can be actuated.

FIGS. 8A, 8B, 9A, 9B, 10A and 10B show details, possibly various locking devices 43, comprising various locking elements (20, 27) in different positions (in each case as a sectional view). 8A shows a detailed view of a side sectional view of a door 1, wherein the locking element 20 is formed as a bolt 21. According to Fig. 8A, the bolt 21 in the unlocked position, i. H. in the open position of the locking element 20, shown. According to Fig. 8B, the bolt 21 is shown in the locked position. The bolt 21 engages in the locked position (FIG. 8B) in a locking receptacle 24. The locking receptacle 24 is formed such that the bolt 21 can be inserted at least in sections into the receptacle 24. The receptacle 24 has a substantially cylindrical geometry, wherein the substantially cylindrical pin 21 is inserted into the receptacle 24 with some play. The receptacle 24 is located in the bottom 9 under the bottom door leaf third

According to FIGS. 10A and 10B, the locking element 20 is formed as a hook 22, which is pivotable into a locking receptacle 24, which is arranged in the bottom 9 and formed as a pocket 23. In the pocket 23 is a rod 25, interacts with the hook 22 for locking. In the locked state, the hook 22 engages behind the rod 25 in the pocket 23. The hooks do not necessarily require a return means.

Bolt 21 and hooks 22 according to FIGS. 8A / B and 10A / B are arranged between the frame side parts 8, ie approximately in the middle of the door. It can be provided at very wide gates several bolts / hooks, such as a locking element 20 in the region of right half of the goal and one in the area of the left half of the goal. In addition, a Torflächen- or center lock 44 may be provided.

The bolts 21 are actuated against the force of a spring. In this respect, the locking device comprises a return means. Accordingly, it requires opening a tensile force by means of drivers 19 against the action of the spring. When closing the tensile force is released and the spring pushes the locking element (21) in the corresponding receptacle (24).

A side latch 26 can be seen from the details of Figures 9A and 9B. The opened side lock is shown in Fig. 9A, the closed one in Fig. 9B. According to FIG. 9B, the laterally acting locking bolt 27 engages in a recess 28 in one of the frame side parts 8.

A spring element 29, which acts on the locking bolt 27, can also be taken from FIGS. 9A and 9B. The spring 29 presses against the bolt 27, so that the bolt 27 is moved to unlock against the action of the spring 29.

The driver assembly (19) for actuating the side lock 26 can be seen in Figures 1 and 9A / B. Accordingly, at least one drum 17 is rotated before lifting the door 1, that is, during the freewheel of the drive shaft 15, whereby a driver 19, namely at least one cable 30, is moved. About a deflection system 31 with pulleys 32, the initially vertical traction of the traction cable 30 is deflected into a horizontally acting tensile force. In the area of the side lock 26, a direction reversal of the tensile force takes place by means of a deflection roller 33, whereby the locking bolt 27 can be moved away from the frame side part 8 (unlocking) or towards the frame side part 8 (locking). The locking takes place following the closing movement of the door 1 during the free running of the shaft 15, the unlocking during the freewheeling before lifting the gate 1. Referring to Figures 1 to 10A B includes the gate 1 in addition to the known means of locking 44 a right Seitenver- lock 26, a left side lock 26 and a bottom-acting locking (20).

For each side lock 26, a drum 17 may be provided in the drive or center console 16. There may be a (coupled) side and bottom lock driver with a (common) drum. On each drum 17 is a pull rope 30, which is guided over components of the deflection device 31 to the side latches 26. A frontal detail view of the center console 16 can be seen in FIG. 7.

The drive motor 18 or a console for the drive motor 18 may alternatively be provided in the region of the frame side parts.

A perspective view of the door drive device 42 with the console 16 can be seen in FIG. 11. Accordingly, the console 16 comprises a console frame 35 on which a motor mount 36 is arranged. The motor 18 is fixed to the motor mount 36 by screws. In the console frame bearings 37 are arranged for receiving the drive shaft 15. The drive shaft 15 is rotatably connected to the motor 18. On the housing of the motor 18, a rectifier module 38 is arranged. By supporting and guiding the gate 1 in a weight-balanced manner by means of weights 13, comparatively small torques for lifting / lowering the door 1 must be provided by the motor 18. The fastening of the center console 16 to the lintel 5 is effected by mounting plates 39.

11, the drum (s) 17 can be removed, which is (are) non-rotatably mounted on the drive shaft 15. The drums 17 are thus rotated with the shaft 15. In this case - depending on the direction of rotation - per drum 17, a pull cable 30 and / or an additional traction element 34 for offloading or wound up. The cables (30, 34) are guided to the console center via a guide element 40 arranged on the center console 16. From there, the ropes are guided in a vertical direction, either to one Deflection device 31 or to a gate (2, 3) or to a locking component (20, 21, 22, 26, 27).
