Description

The invention relates to a sectional or folding gate that verti Kal is displaceable and consists of several sections, be neighboring sections face horizontally along the front Pivot axes are pivotable relative to each other, with a door, which consists essentially of frames and a door leaf, the Door leaf made of several door leaf sec is composed, the swivel axes coaxial to the Sections pivot axis.

Sectional or folding gates have long been known and in use. They are made of lamellar, essentially rectangular plate-shaped gen sections, whereby two vertically adjacent sec tions along a common, horizontal pivot axis, the runs parallel to the long sides of the sections, relative to each other are pivotable. As material for the sections u. a. Leichtme tall such as B. aluminum used. A distinction is made between lifting gates, in which the sections essentially move around during lifting 90 ° and the gate parallel when opened runs to the ceiling, and folding gates where the neighboring sections fold up like a leporello during opening. This Gates are used to create large openings in buildings to be able to lock, for example, garage or industrial doors without using swinging out rigid door panels the.

To allow an individual to pass through the gate, It is known to open doors into this without having to open the entire gate  Integrate gates, with the door leaf also consisting of several relative ones mutually pivotable sections is composed, and the Swivel axes of these door leaf sections coaxial to the above be written swivel axes. The door is to raise the Stability of the construction in one from vertical and horizontal existing frames used door frames. These doors should also used as escape doors, for example in the event of a fire if the gate no longer opens in the usual way leaves.

As a disadvantage with the previously known gates with an integrated door it can be seen that at the bottom of the doors there is always a horizontal running frame or threshold is arranged, which is particularly in need cases where it is necessary to leave the building quickly, represents a stumbling block over which people fall and ver can last or the evacuation of the building is delayed. This threshold has so far been considered essential because it is one on the one hand, the entire door construction is used in the closed position stood to give sufficient stability and on the other hand ver it is avoided that the floor twists when the gate is opened side section occurs perpendicular to the main plane of the gate. Also will in the case of positive contact of the door leaf with this stable to the Door opening surrounding the door frame prevents the move pivotable sections of the door leaf relative to the gate. This threshold is also the reason why such doors are not considered Escape route to be recognized.

Starting from the prior art, the invention has for its object asked to design a lifting or folding door with a door in such a way that  the horizontal threshold below the door leaf can be omitted without reducing the structural stability of the gate is impaired, as well as a torsion of the door sections or a Relative movement of the door leaf to the gate during opening does not occurs.

According to the invention, this object is achieved in that the door leaf extends to the floor when the gate is closed, the door leaf or frame is provided with at least one opening, at least one thrust pin axially, in the main plane of the gate hori zontally movable in the bottom area of the frame or door is arranged and the push pin in the closed door Opening engages.

The main idea of the invention is that the door leaf with at least one push pin and at least one of them moving locking element festge relative to the frame and thus the gate is laid. The thrust pin is axial, i.e. H. along its longitudinal axis, in horizontal direction in the main plane of the gate slidable. It can either surround the door leaf or in the door the frame can be arranged. One is in the frame or opening in the door leaf is available, which with the displaceable ren push pin corresponds, d. H. their depth or diameter is matched to the dimensions of the push pin. To the lock When the door leaf is closed, the push pin which is arranged in the bottom area of the door leaf or frame is axially displaced and thus brought into engagement in the opening, and lower a movement of the door leaf or its bottom section prevented right to the main level of the gate. This is the push pin  ideally on the side of the door opposite the hinges leaf arranged on which there is also a door handle and lock.

The advantage of the invention is that due to the extension the door leaf to the floor, d. H. the lack of a potential Trip hazard in the form of a threshold, ver this door as an escape route is reversible. In addition, at least when lifting the gate bottom section of the door leaf relative to the surrounding door section fixed and thus a torsion of the gate or a Relativbe movement of the door leaf to the gate prevented.

Advantageous embodiments of the invention are the subject of Un claims.

An advantageous further development of the invention is that the push pin when moving into the opening next to the opening attached in the movement cross section of the push pin protruding, swiveling locking element (e.g. a pawl) pushes or pushes to the side, this with a peg-like out formed end behind the edge of one also referred to as an abutment grips and locks the retaining strip on the door or gate segment. By the Swiveling and then snapping the locking element is a movement of the door leaf or at least its bottom side Section in the main level of the gate itself prevented.

If the push pin is located in the door leaf and they belong to it de opening in the frame, then the locking element must also be in The frame is located and reaches behind the retaining bar, which is then on the door sheet is attached.  

The door leaf or the ones surrounding the door are advantageously Frames with several of the push pins and rie described above gel elements. This means that the door leaf can be used in several places be determined, and in particular for one of several sections The push pins and bolts can be used to assemble the door leaf elements in the lateral lower and / or upper edge areas of the Door can be arranged to allow relative movement of each door to avoid leaf sections.

It is proposed that the axially displaceable thrust pin in the Frame and the corresponding openings in the door leaf bring. In this embodiment, it is possible to be the below written drive of the push pin also on or in the area of Frames, d. H. to accommodate in the gate.

Alternatively, the push pins can also be in the door leaf and the opening openings in the frame. The energy supply, at for example a power line for an electric bolt drive, can in a suitable manner, for. B. with flexible cables, from the gate be guided into the door leaf.

It is proposed that the push bolts be driven electrically magnetic, e.g. B. via electric servomotors or with a magnetic scarf tern, hydraulic or pneumatic with the hyd known to those skilled in the art raulik- or pneumatic system, or are mechanically movable. A Mechanical mobility of the push pin can, for example like a snap lock used in conventional doors  done, d. H. the push pin is moved with spring force and in engaged the opening. The tip of the pushbolt can be used for this zens can also be rounded off in a hemispherical shape to engage and disengage out of the opening. Furthermore, it is the expert possible to attach any mechanical device that the Push pin locked in the closed position as soon as the gate is raised becomes.

Another advantageous embodiment of the invention consists in that at the bottom of the door leaf more bolts in the main level ne of the gate are arranged vertically, which can be moved, and, in the closed state of the gate, in corresponding ones Can intervene in the floor. One may be for sure safety concerns desired or required additional shift Availability of the bolt can also be in the manner described above will be realized. In both versions, the bolts serve initially to stabilize the gate when closed, d. H. that a movement of the gate and door perpendicular to its main plane is prevented. Such a movement, for example under the Influence of strong wind pressure would damage the Lead tores. The additional displaceability of the bolts over one The drive can be used as an additional safeguard, especially in the door area serve against unauthorized use.

The length of the bolts is advantageously three to eight times of the bolt diameter. With a suitable choice of materials, in particular Metal or stainless steel, bolts with such dimensions absorb a maximum bending moment perpendicular to its longitudinal axis, without deforming under its influence.  

In an advantageous embodiment of the invention, at least tens two of the vertically arranged bolts, the axially displaceable Push plunger, the movement of the push pin driven. This can the upper area of the two push rods is designed as a toothed rack be the one with their vertical upward movement, the one over gears and a steel band is deflected, the thrust pin from which listening opening pulls.

The push pin is advantageously against a compression spring moved, which is stretched by the movement.

Overall, the push pin is returned when the gate is closed moves away and the door is released. When you open the gate they jump Thrust pin, driven by the relaxation of the compression springs, back into the openings and lock the door.

At the same time as this process, the door segments through the Secured locking elements that snap behind the retaining strips, as above ben described.

Overall, these devices acting together will Door locked when opening the gate and after closing for the Released for use.

To increase the safety of use of the gate, it is proposed that an electrome known per se at the bottom edge of the gate chan security bar is arranged, in which a strip-shaped Encoder is movable in the vertical direction against a spring force.  

Should there be an object or a person when the gate closes are located below the gate, the contact strip is through the counter the object moved relative to the gate and an electrical contact closed, the ver with an automatic shutdown for the door operator is bound. The safety bar is advantageously made up of three parts leads, d. H. that left and right at the gate and at the door on the A ledge is attached to the bottom edge. The specialist can do this partially the strips in a suitable manner so electrically ver bind that when only one bar triggers the automatic shutdown tic reacts and switches off the gate operator. This is security guaranteed when staying under all three gate parts.

Another advantage is a device with which the most un vertically attached part of the protective contact strip Kal can be pivoted or raised because the door is only opened slightly can if the contact strip is not on the floor.

A drive can be switched on to lift the contact strip off the floor builds his when opening the door, e.g. B. already when pressing the Doorknob, is activated.

In order to use the door as an escape route, it is equipped with a panic lock known to the expert. This he also allows opening a locked door from the inside for example by simply pressing the doorknob. So that is enables rapid evacuation of people from a building, even if they do not have a suitable key for the door put.  

In the case of a drive provided, the vertically extending bolts the lower edge of the door leaf is recommended, it in operative connection with the door handle or the door lock. That means that at Actuation of the door handle or door lock, for example around the door to open, the bolts are moved synchronously. They have to to open the door upwards out of the openings in the floor pulled and inserted when closing.

The bolts can also be driven as described above, and it can e.g. B. when opening the door, an electrical contact ge be closed by an electric or magnetic bolt drive sets in motion. In particular, a mechanical action proposed connection between the bolt and the door handle, which consists of a Linkage exists, this at the level of the door lock with a Toothed rack is equipped, which is in direct engagement with a ge serrated quadrant that stands over the doorknob around a horizontal Axis is pivoted. The linkage or the ver with the bolt tied push rod must be at the level of the horizontal swivel axes on which the individual neighboring sections are relative to each other are pivotable, also have a coaxial joint conditions to enable the folding or folding process when opening the door lichen.

To prevent the door leaf from moving in a horizontal direction the door leaf and / or the verti kalen frames equipped with hook-like devices that correspond accordingly shaped projections on frames or door leaf in the closed Reach in on the condition of the door. In particular, these hooks in  Area of the bolts arranged to open the gap between rule door leaf and frame, z. B. to prevent during opening.

Another advantageous embodiment of the invention consists in that on both narrow sides of the gate in the lower area press roller is attached, which when closing the gate to a cent locking or locking curve that runs in the lower area of the door frame is appropriate. This will make the gate and door in the lower area merged, fixed their position and the bolts over the Centered openings.

This ensures that the push pin fits snugly into the opening is introduced, wherein the locking element is pivoted so that it engages behind the retaining bar and at the same time the electrically conductive Contact between the individual parts of the safety contact strip manufactures.

So that the purpose of accurate centering is achieved, the one The height of the locking mechanism ensures that it functions properly the centering or locking curve advantageously designed to be variably adjustable, so that it can be readjusted at any time.

In the embodiment of the invention shown in Fig. 1, it is a sectional lifting gate, which consists of several, in wesentli Chen rectangular sections ( 1 ) which are pivotable relative to each other on horizontally extending pivot axes ( 2 ) parallel to their long sides. In order to make it possible for people to pass the gate without having to open the gate itself, a door is used, the door leaf of which in turn is composed of individual door leaf sections ( 4 ), the horizontal pivot axes ( 5 ) between adjacent door sections ( 4 ) are arranged coaxially to the above-mentioned pivot axes ( 2 ) of the gate. At the bottom edge of the gate and the door a three-part electrical Schutzkon contact strip ( 3 ) is attached, which is coupled to an automatic shutdown for the Toran drive.

In Fig. 2 the lifting gate is shown in the half-open state. Here, in the angle between the wall and the ceiling, the individual sections ( 1 ) pivot essentially by 90 ° in such a way that the gate runs parallel to the ceiling in the fully open state.

In Fig. 3, the two bottom, bottom sections ( 4 ) of a door of a lifting gate according to the invention are shown in the closed state. The bottom section ( 4 ) lies essentially in a form-fitting manner with its lower edge on the floor ( 6 ); an additional rubber lip can also be attached to it for sealing. A arranged in the main plane of the gate, possibly in the vertical direction axially displaceable bolt ( 7 ) here engages in a corresponding opening opening ( 8 ) in the bottom ( 6 ) below the gate, as indicated by the arrow. This prevents movement of the gate or the door perpendicular to the plane of the gate, for example under the influence of the wind pressure. Between the two sections ( 4 ) is arranged a pivot axis ( 5 ) which can be designed by a person skilled in the art and on which the two sections ( 4 ) can be pivoted relative to one another. Furthermore, a push pin ( 9 ) is shown, which can be brought into engagement in a frame ( 10 ), wherein it can be moved axially, perpendicular to the image plane. To simplify the illustration, the illustration of a drive device for the bolts ( 7 , 9 ) was dispensed with.
