EP2699749B1 - Base profile locking for the x-axis and the y-axis of a sectional gate or a sectional lift-fold gate that comprises a closing edge safety device and an escape door having a trip-free threshold - Google Patents

Description

The invention is directed to a base profile for a sectional gate or a sectional lift-folding door with closing edge safety and with an escape door without trip threshold, as well as with non-positive connection within the x and y axis, as well as with a buckle safety without Load on the door rails.

Sectional doors are already known and have conquered in recent years - in addition to roller doors - a large market share under enormous cost pressure.

In order not to have to open the gate completely for every passenger traffic and small transport, as in winter, the various sectional door manufacturers have followed the architects' wish to equip doors with a so-called wicket door.

The execution of a door with wicket door reduces the construction and strength of the entire door because of the modest in cross-section and in height execution of strength, and therefore requires for reasons of stability, at least one door sill, which forms a dangerous stumbling threshold.

In the textbook by Günter Lippe "Sektionaltore"; Kleffmann Verlag is quoted as saying: "A wicket door can not be integrated without a threshold into a door leaf, so it can never assume the function of an escape door."

Previous efforts to make a sectional door without trip threshold marketable, failed as a rule, because you tried, the base profile tubular in order to stiffen this by sliding stabilizers at the seams between door curtain and door so that inserted stabilizers should take over the function of a continuous base in a door without a threshold. Such an arrangement is, for example, the DE 200 13 512 U1 refer to. However, it has been shown that with a renewed base stiffening by the sliding stabilizer with each actuation alternately a fateful burden of each unstable door runners can arise, which in this case not only have to absorb the caster movement, but also the transverse forces of the sliding stabilizers.

Furthermore, is still the DE 10 2004 047 166 A1 to mention. There is an attempt to pivot for each stiffener between door panel and door in the baseboard at each contact point - ie lock and hinge side - two pivotable in opposite directions hook elements behind the respective hook pivot axis parallel locking bolt or hook. Due to the opposite pivoting directions, the holding forces can each brace against each other to avoid accidental unhooking. However, then a total of at least four such hook elements provide, which brings a not inconsiderable design effort with it.

Based on this situation, a so-called "low-threshold" was designed by various manufacturers, with a height of between about 5 mm and 30 mm high. So far, however, recognizes the professional association a door with a threshold, regardless of their height, in principle not as an escape door. As the inventor knows, the trade association recommends the use of a low threshold for doors in a sectional door. This statement is due to the fact that there is still no manufacturer for sectional doors with a real escape door without any threshold.

From the described disadvantages of the prior art, the problem initiating the invention to design a sectional door or sectional lift folding gate with a base profile with closing edge safety and with an escape door without trip threshold, with the lateral or transverse forces on the rollers always remain negligible small, and further wherein the additional design effort should be as low as possible, so that the mechanism to be created can compete with currently available door panels including the sliding door price moderately.

The solution to this problem succeeds in a base profile for a sectional gate or a sectional lift-folding door with closing edge safety and with an escape door without trip threshold, by the base profile

1. a) is separated in the region of the vertical edges of the escape door over its entire cross-section to allow the installation of the escape door on the lock side and / or hinge side, and
2. b) has at least one locking niche with an approximately U-shaped or approximately half-round cross section on the one hand,
3. c) as well as at least one locking element which can be pivoted in or gripped around it,
4. d) wherein the locking niche and the pivoted therein or thereof embraced locking element with lowered sectional or sectional lift-folding gate and open or einschwenkender escape door lock side and hinge side of the locking element are each separated by at least one gap with sufficient contact tolerance,
5. e) while the pivoted into the locking niche or embraced therefrom locking element with closed escape door and raised or raised sectional or sectional lift folding door lock side and hinge side non-positively in each case without gap in the locking niche and consequently the adjacent base portion frictionally with the door section of Socket profile connects,
6. f) wherein at least one locking element and / or at least one locking niche each having a cylindrical or prismatic structure with mutually parallel longitudinal axes and with variable, but at least partially constant in the longitudinal direction constant cross-section, wherein a non-positive connection between a locking element and at least one locking niche by a pivoting movement of Locking element is effected within the locking niche, and wherein the pivoting movement is preferably carried out to a relative position with self-locking effect.

The locking elements and niches according to the invention are separated from each other by at least one gap with sufficient contact tolerance, so that the escape door can move relative to the adjacent door panels at lowered sectional or sectional lift-folding gate and open or einschwenkender escape door lock side and hinge side , However, with the escape door closed and the sectional or sectional lifting-folding gate lifted or raised, they are non-positively connected to one another on the lock side and hinge side and thus connect the base sections adjacent to both sides in a force-fit manner, so that the escape door is connected to the adjacent door panels , The installation of a continuous closing edge safety device is also possible in the area of the escape door.

The invention thus creates a detachable connection between the various base parts or between the escape door and the adjacent door panels, the side rollers remain completely free of forces. This is preferably achieved by interlocking locking parts, wherein a locking element, for example. Is controllable such that it fills a locking niche in its entire width in a first state and thus contact with the two flanks of Locking niche, which corresponds to the locking state, the escape door is rigidly connected to the surrounding door curtain, so to speak, a stiff part of the same, while in a second state, not the entire width of the locking niche is filled, which corresponds to the solution state, the escape door open can be. In this case, the width of the locking niche can extend parallel to the plane of the door leaf or the door shell, so that the locking effect occurs primarily within the relevant level, ie, the door is received in the structure of the door curtain and then defines its entire width in the region of the escape door ,

The invention further provides that the profile cross section is separated on both sides of the escape door, and the base portion between the two dividing lines is connected to the escape door, so that with lowered door curtain and when swinging the escape door with the ground level same escape route, ie without any threshold and even without any 'low' threshold.

Preferably, the locks are motor-actuated, eg. Via a push rod and possibly by means of a toggle which converts the pushing movement of the push rod in a pivotal movement of at least one locking member, and / or by means of a toothed push rod which meshes with at least one gear segment and thereby their thrust movement as pivoting movement to at least one locking part passes.

It is within the scope of the invention that the push rod is actuated by an electric motor, preferably a gear motor, in particular with a low nominal voltage, for example by a windscreen wiper motor. Such is relatively small and therefore allows an advantageous development to the effect that the mounts of the engine are located in a base profile of an adjacent door shell, so that no lateral forces are transmitted to the respective gate rails.

The invention recommends that between the push rod and the motor, a reduction, in particular a reduction gear, is provided, preferably in the same base profile, wherein the motor can be arranged. Such a reduction makes it possible to use small motors, which require little power or electricity, and yet make it possible to develop increased forces.

The push rod can be designed such that it with delay in the escape door base, in particular in a local centering retracts, and preferably has a stroke of about 20 to 30 mm. By such a measure can be achieved that different locking devices are actuated sequentially in a chronologically well-defined sequence and the escape door is aligned piece by piece relative to the door armor, so that a clamping is not to be feared.

In another embodiment, it can be provided that the push rod can be connected via a coupling with a door push rod arranged in the escape door base.

The invention can be further developed such that at least one further locking in the region of an edge of the escape door facing away from the engine is actuated by the door push rod arranged in the escape door base, in particular in the region of the hinge side of the escape door. Thus, a single motor is sufficient to operate all locks.

The invention is further distinguished by at least one locking rocker or a locking hook, in particular with a locking niche of approximately U-shaped or approximately semicircular cross-section, whereby upon actuation a preferably axis or rod-shaped locking element with preferably circular cross-section connects non-positively.

With great advantage, the locks and in particular the interlocking locking members are arranged such that a force direction lying within or parallel to the plane of the door curtain connects a pivot axis and a contact point of a locking part or two points of contact of two locking parts, so that none of the locking or disabling the locking Transverse forces can arise.

According to the invention, the latches and in particular the interlocking locking parts take over the tensile and / or compressive stresses occurring in the locked state in the base profile without generating transverse forces, in that their points of contact in each case lie neutral in the line of force. The main purpose of the interlocks according to the invention is an alignment of the sections of the interrupted door shell with each other and with the relevant section of the escape door. In order that such a sectional or lifting folding door can be opened smoothly despite this locking, the aligning forces should be within the level of the section concerned maximum, so as to avoid misalignment of individual sections, while transverse forces perpendicular to this level but rather minimal should. An alignment of these Torabschnittsebenen in a common flight results rather by the rolling up or folding the door in a straight line aligning folding lines. Only in the fully pushed-up area of a sectional door with local deflection in a horizontal plane this stabilization effect is missing. For this case, two latches should be arranged at at least one point of the base according to the invention such that the connection line between them, in particular between the respective contact areas, is directed approximately perpendicular to the plane of the relevant section. This can also be a stability against a To achieve unintentional evasion of the various sections of the goal shell and the escape door within a section of a common plane.

Further advantages are offered by a manual unlocking possibility in the event of a power failure, in particular via an (intermediate) gearbox which is coupled or coupleable to a push rod and / or to a manual actuating element.

Furthermore, the invention enables a closing edge safety system that is also continuous in the area of the escape door. This should cause a shutdown of the door drive even with a slight contact between the closing edge of the gate and an obstacle to avoid injury to persons and damage to objects. In most cases, a sensor is present whose sensing region extends along the entire closing edge. For example. a circuit is closed or interrupted upon contact of the closing edge with an obstacle, and as a result the door drive is stopped.

A design rule according to the invention provides that the closing edge has a rubber profile with a longitudinally extending switching chamber with elongated, electrical switch contacts inside the switching chamber, the mutual contact represents an electrical contact originally against each other insulated elements, which is electrically visible and cause the triggering of a safety relay can stop the movement of the door or door curtain and the door immediately via a safety circuit, whereby persons and material are reliably protected.

Within the framework of the closing edge system, an extruded rubber profile with preferably two copper strands may be used, preferably two conductive but usually mutually isolated rubber layers, which serve as buttons, within the switching chamber of the rubber profile and upon contact trigger a current flow or voltage drop, which is continuously monitored by the transmitter, for example. By comparison with a quiescent current.

The rubber profile should be separated in the area of the escape door, whereby the seamless transmission of a voltage or a quiescent current at the hinge side can take place via an offset cable gimbal, while the seamless transmission of the voltage or the quiescent current at the lock side in the door socket takes place via a stationary isolated panel socket. which is reliably connected when closing the door by an isolated plug moved by the push rod, in such a way that the plug is made with sufficient delay of the closing path and the exact alignment of the escape door.

Finally, it is the teachings of the invention that near the hinge side below the base is a weakly sprung vertical resistance wind tappet, which retracts when the door is closed in a bottom escutcheon and can absorb relatively high horizontal forces, being in the vicinity of the lock edge below the base preferably also such a device is located. This measure counteracts evasion of the door curtain from a common plane.

In the drawing, 1 denotes a sectorial or sectional lifting-folding gate. The tank 2 of these gates 1 each comprises a plurality of slats 3, which are arranged one above the other in the manner of a shutter and hinged together. In a sectional door 1, one or more, preferably all slats 3 each have lateral rollers 4, which are guided in lateral, on a wall 5 od. Like. Specified door guide rails 6 and performed accordingly when lifting or lowering the tank 2. A sectional lift-folding door 1 is characterized in that the blades 3 fold up during lifting in the manner of a bellows.

Preferably, the individual lamellae 3 each have a jacket or frame 7, for example of a metal sheet, which is provided with a filling 8 of a preferably light, but thermally insulating material, for example. A (hard) foam such as polystyrene.

How to get out of the Fig. 1 to 3 can take, the slats 3 are severed at the height of a door 9, and preferably there is between the door section 9 and the two, laterally adjacent lamellar sections 10, 11 each have a gap 12, which should allow a smooth opening and closing of the door 9.

Each door section 9 is permanently connected via a hinge 13 or the like to an adjacent fin section 10. The hinge 13 includes or forms a vertical pivot axis 14 about which the door 9 springs open when opened. This pivot axis 14 of the hinge 13 is displaced to a flat side 15 of the tank 2 or even beyond, so that the door 9 is not jammed in the region of the hinge 13 when opening. This flat side 15 of the tank 2 is to be referred to below as "opening side", the other flat side 16 of the tank 2, however, as "back".

A connection with the other fin section 11, however, takes place only when needed, i. with the door 9 closed, via a socket profile 17 according to the invention, which preferably connects only the respectively lowest lamella sections 9, 11 to one another. This connection can be locked and unlocked, in particular automatically, if necessary, but in addition also manually, for example. In order to open the door 9 at risk and simultaneous power failure yet.

How to do that Fig. 7 and 8th can take, extends the base profile 17 along the lower edge 18 of the bottom plate 3 over all the local sections 9 to 11 of time and is preferably arranged on the back 16 of the tank 2, to the side of the door 9 does not swing open. To avoid jamming, a horizontal section through the door portion 19 of the base profile 17 may be slightly trapezoidal, with the longer base side of this trapezoid facing the door 9, the shorter base side, however, facing away from the door 9.

Within the hollow profile formed as a base profile 17, preferably in a laterally adjacent to the door portion 19 base portion 20, 21, In particular in that base portion 21 which has no hinge 13, there is sufficient space for a motor 22, for example an electric motor, preferably for a geared motor, in particular for a windscreen wiper motor.

This drives, for example, a rotatable about the longitudinal direction of the base profile 17 screw 23, whereupon a non-rotatably guided threaded sleeve 24 is schraubverstellbar. This threaded sleeve 24 could be connected directly to a push rod 25. Preferably, however, a reduction gear 26 is still interposed. For this purpose, the threaded sleeve 24 is connected to a running in the longitudinal direction of the base profile 17 threaded rod 27. This meshes with a first gear 28 which is rotatably connected to a second gear 29, which is smaller and has a smaller number of teeth than the first gear 28. With the second gear 29 meshes a toothing on the push rod 25. The push rod 25 moves slower than the threaded sleeve 24, but with a higher force.

In its front, the door 9 facing region, the push rod 25 has at least one extending in the longitudinal direction of the teeth 30, 31 or via a circumferential toothing or a circumferential thread.

With the teeth 30 or a thread of the push rod 25 meshes a toothing 32 at the free end of a arranged on a rotatable about a vertical axis bolt 33 arranged extension 34. Due to this tooth engagement, the bolt 33 rotates upon displacement of the push rod 25 about its preferably vertical axis of rotation.

The jacket of the bolt 33 is not completely rotationally symmetrical. He may, for example, have an elliptical or egg-shaped cross-section or - as in the FIGS. 5 and 6 shown - next to a larger circular shape with diameter D still attached thereto, smaller, preferably also have circular satellite 35 diameter d. This may, for example, be formed by a rod welded to the jacket of the bolt 33. Consequently, this entire structure in the main axis-that is, if bolt 33 and satellite 35 are measured together-has an extension h = D + d, and in the transversely directed minor axis only a maximum extent n = D such that n <h.

When the door is closed, the bolt 33 mounted on the base section 21 is located within a recess 36 which is formed by an invagination of the frame 7 of the door 9. This recess 36 or indentation has an approximately rectangular, in particular rectangular or square cross-section, thus approximately the shape of a groove whose two side surfaces 37 are oriented approximately perpendicular to the flat sides 15, 16, the base or bottom surface 38 approximately parallel thereto. The distance a between the two side surfaces 37 of the groove-shaped niche 36 is greater than n, but equal to or slightly smaller than h: $$\mathrm{n}<\mathrm{a}\le \mathrm{H}\mathrm{,}$$

Depending on the rotational position of the bolt 33, this can thus move freely in the groove-shaped niche 36, as in Fig. 5 is shown, or he is stuck, as in Fig. 6 is shown. In the first position, the door 9 can be opened and closed again, while the sectional door 1 must remain closed; in the latter position, the tank 2 can be raised and lowered again, while the door 9 must remain closed.

In the rotational position of the bolt 33 according to Fig. 6 is the door portion 19 immovably connected to the base portion 21 in the x-direction, symbolized by the arrows 39 forces in the x-direction, ie parallel to the plane of the closed shell 2 and horizontal, on the bolt 33 perform neither a torque nor lateral forces , for example, in the y-direction, so perpendicular to the plane of the closed tank 2 generate, because the two Points of contact of the bolt 33 and the satellite 35 on the other hand, each with a side surface 37 of the niche 36 lie pretty much on the same x-axis.

In this case, this locking device is supported by the door hinge 13, which connects the door section 9 with the adjacent fin section 10. As a result, in particular, all sections 9 to 11 of the lowermost slat 3 are firmly connected to each other, and the tank 2 can be lifted safely.

On the other hand, at least the lowermost lamella 3 should also be stabilized in the y-direction, so that in particular the raised tank 2 of a sectoral door 1 in a raised position - if it od by a deflection of the door rails 6 an approximately horizontal plane on a garage ceiling. Like. - Not - or at least not sag too much.

This function can fulfill the skirting 17 of the invention. For this purpose, two more locks are actuated in the locked state. One of them is in Fig. 3 in the region of the right-hand gap 12 between the door base portion 19 and the adjacent Panzers-Sockelabsctinitt 21. These are a bolt 40 in the door base portion 19 on the one hand and a hook-shaped element 41 which is non-rotatably mounted on a vertical axis 42 and pivotally mounted with this within a horizontal plane to the adjacent armor base portion 21. Located on the axis 42 is a further extension 43 approximately horizontally projecting rotationally fixed. This extension 43 has an arcuate periphery with a toothing 44, which in turn meshes with the toothing 31 on the push rod 25. During their advancement, the axle 42 is rotated while the hook-shaped element 41 is pivoted about the door-side bolt 40. In this case, these two base sections 19, 21 are connected to each other, but clearly offset in the y-axis relative to the bolt 33. By this offset these form two latches 33, 41 for the raised and horizontally deflected tank 2 a kind of top and beam and thus give him a high stability in the y direction.

The lock 41 is supported by a further lock 45 in the region of the gap 12 between the door portion 19 and the opposite base portion 20. This also includes a fixed pin 46 on the one hand and this in the locking state encompassing hook-shaped element 47, which is a vertical Axis 48 is pivotally mounted.

In order to control this lock 45 automatically, the hook-shaped element 47 should be coupled to the same motor 22 as the other locking devices 33, 41. On the other hand, the door 9 can be opened, the relevant coupling device 48 must be separable in the region of a door gap 12. The coupling device 48 thus comprises a separate from the push rod 25 coupling rod 49 which is movably disposed within the door base portion 19 and coupled with its peripheral, ie, the motor 22 opposite end to the hook-shaped element 47 to the pivot drive, as in Fig. 3 to recognize.

The releasable coupling of the coupling rod 49 with the push rod 25 is in Fig. 4 clearly visible:

The coupling rod 49 has at its end facing the motor 22 a thickening 50 with a flat front 51 for the purpose of pressure system on the front end 52 of the push rod 25. To precisely meet the coupling rod 49 in the linear actuator, a sleeve 53 is provided which on the one hand, the thickening 50 leader receives, and on the other hand when advancing the push rod 25 centered this and then precisely to the front 51 of the coupling rod thickening 50 brings. As soon as the two surfaces 51, 52 lie against each other, the coupling rod 49 completes the further thrust movement of the push rod 25 after. In this case, the hook-shaped element 47 is pivoted about its axis 48 and finally engages behind the fixed pin 46 of the base portion 20. Now the locking state is reached and the tank 2 can be raised.

After the tank 2 is lowered again and the door 9 is to be opened, the lock 45 must be released again. For this purpose, the coupling rod 49 must be withdrawn by means of the push rod 25. For this purpose, a latchable on train latching 54 between coupling and push rod 49, 25 is provided, which is actuated upon penetration of the push rod 25 into the centering sleeve 53.

In the context of this latching 54, a recess 55 is provided on the push rod 25 at a distance to the front side 52, with an approximately parallel to the front side front 56. In this recess 55 can engage a hook-shaped element 57, which in the end thickening 50 at the rear end of the coupling rod 49 - preferably about an approximately tangential to the lateral surface of the thickening 50 extending axis 58 pivotally - is hinged. Stop elements 59 on the axis 58 can limit the pivoting movement of the hook-shaped element 57 between an hooked position and an unhooked position. A spring 60 endeavors always to press the hook-shaped element 57 into an end position, in particular into the hooked end position. This may be a helical spring that is preferably wound several times around the axis 58, whose two ends are coupled to the thickening 50 on the one hand and to the hook-shaped element 57 on the other hand. A further stop element 61 is arranged stationarily in the door section 19 of the base element 19 and causes the hook-shaped element 57 pivoted into the notched position, as soon as it is retracted by means of the hooked rod 25 behind a corresponding position. Then, the hook-shaped member 57 remains in this open position due to the contact with the stopper member 61 and allows the door to be opened 9. If, on the other hand, after closing the door 9, the push rod 25 is advanced again, the hook-shaped element 57 finally comes free of the stop element 61 and can then latch into the recess 55 of the push rod 25.

In the drawing, especially in the Fig. 1 . 7 and 8th It can also be seen that the skirting board 17 according to the invention is provided with a closing edge safety device which extends over all the base regions 19 to 21. For this purpose, an elastic profile 62 is attached to all of these base sections 19 to 21 on the underside, for example, a rubber profile, which may be formed as a hollow profile, with an inner cavity 63 which is designed approximately U-shaped, such as in Fig. 7 to see. This cavity 63 is delimited by a thin, underside, approximately cross-sectionally U-shaped cross-sectional area 64 on the one hand and by a spring-like strip 65 with a relatively sharp cross-section engaging at a considerable distance therebetween on the other hand. The inside of the U-shaped cross-sectional area 64 and the free edge of the spring-like bar 65 on the other hand are each provided with a conductive coating, for example. Graphite od. Like., Which are each contacted via a terminal 66, 67. If the lower, U-shaped area 64 is squeezed, for example because it rests on the floor 70 or on an obstacle, then its conductive inside finally touches the conductive coating of the spring-like strip 65, and thereby an electrical contact is established and optionally a Circuit closed, which can be regarded by a controller as an indication that the tank 2 is hit during a closing on an obstacle and must be stopped immediately. This can be effected, for example, via a relay which is activated by the closed circuit and disconnects the supply line of the motor 22.

The two terminals 66, 67 of all base sections 19 to 21 must be merged for this purpose and, for example. Linked together via an element with a logical OR function. The relevant connection lines 66, 67 from the base portion 20 may, for example. In Area of the hinge 13 are transmitted from the base portion 20 to the door portion 19, in particular via a loop there guided, connected on both sides at different heights cable 68, which is hardly loaded when swinging the door 9. The transfer of the combined leads 66, 67 from the door portion 19 to the motor 22 accommodating the base portion 21 can then be done via two or more plug contacts 69, the pins are slidably guided in the base portion 21 and taken from the push rod 25 and after centering in the sleeve 53 are inserted into the designated, door-side jacks. A time delay which enables the preceding centering is achieved in that the plug pins have a greater distance from the bushings than the push rod 25 from the centering sleeve 53.

To anchor the tank 2 in the closed state of the door 1 in addition to the bottom 70, one or more, approximately vertically downwardly projecting, preferably spring-mounted in its longitudinal direction pins 72 are provided in the region of the lower edge 71 of the base 17, when the door is closed 1 can engage in corresponding recesses in the bottom 70 and prevent depression of the tank 2.

The function of a sectional door 1 or sectional lift-folding door equipped with a base profile according to the invention is as follows:

The lowermost portion of the base 17 is stabilized and locked such that the door 1 on the command of the user "door open" by commander, wall switch, radio, photocell barrier or cable, etc., preferably with a delay of - depending on the type of drive - about two to four seconds, the integrated escape door 9 reliably locked. Thus, the door 1 drive together with the escape door 9 without load on the rails 6 by lateral forces upwards, the sections 3 can orient themselves differently and, for example, be deflected by curved door slides 6 or folded alternately.

The gate 1 and the integrated door 9 remain locked so long until the closing process - the sections 3 lower again and unfold if necessary - the floor is reached and again in about two to four seconds door 9 and door 1 are unlocked ,

A contact of the closing edge rubber 62 in each position of the door 1 during the up or down movement immediately triggers a "stop", and the gate 1 is stopped or moved back up.
