Description

The invention relates to a according to the preamble of claim 1.

Sectional or folding doors have long been known and used. They are made of lamellar, substantially rectangular plate-shaped Sections composed, with two vertically adjacent sections along a common, horizontal pivot axis, the parallel to the longitudinal sides of the sections, relative to each other are pivotable. As material for the sections u. a. Alloy such as As aluminum used. One distinguishes between lift gates, in which during lifting the sections essentially to 90 ° are pivoted and in the open state, the gate in parallel to the ceiling, and folding doors, where the adjacent sections be folded in a fan-fold during opening. These Gates are used to create large openings in buildings, For example, to close garage or industrial doors, without using wide-swinging rigid door leaves.

To allow the passage of the gate for an individual, Without having to open the entire gate, it is known to have doors in them Gates integrate, the door leaf also from several relative is composed of mutually pivotable sections, and the Pivot axes of this door leaf sections coaxial with those described above Swivel axes run. The door is to raise the Stability of construction in a vertically and horizontally extending Used frames existing door frame. These doors should also used as escape doors, for example in case of fire can not be opened if the door does not open in the usual way leaves. Such gates are known from EP-A-0 936 339 and US-A-4 603 723 known to run at the bottom of the gate in the area of the door Frames or thresholds may have, with individual sections the door via horizontally extending push pin with the gate in conjunction stand. Finally, DE-A-3835055 shows only one in one Gate integrated door.

As a disadvantage in the previously known gates with an integrated door is to look at that at the bottom of the doors always a horizontal extending frame or threshold is arranged, especially in emergencies, in which a quick exit from the building is necessary, is a stumbling threshold over which people fall and injure themselves or the evacuation of the building is delayed. This threshold has hitherto been considered indispensable, since on the one hand this is the entire door construction in the closed state to give sufficient stability and otherwise avoided is that when opening the gate twisting the bottom side Section perpendicular to the main plane of the gate occurs. Also will with positive contact of the door leaf with this stable, around the Door opening revolving door frame prevents the pivoting Move sections of the door leaf relative to the gate. These Threshold is also the reason that such doors are not as Escape route are recognized.

Based on the prior art, the invention has the object made to design a lifting or folding door with a door such that the bottom side, horizontally extending threshold below the door leaf can be omitted without the constructive stability of the gate is impaired, and a twisting of the door sections or a Relative movement of the door leaf to the gate during opening is not occurs.

According to the invention, this object is achieved in that the thrust pin in the bottom region of the frame or the Door leaf is arranged.

The essence of the invention is that the door leaf with at least one push pin in the bottom region of the bottom selection and at least one of this mitbewegten locking element relative to the frame and thus set the goal becomes. The push pin is axial, d. H. along its longitudinal axis, displaceable in the horizontal direction in the main plane of the gate. He can either in the door leaf or in the surrounding the door Be arranged frame. To determine is one in the frame or arranged in the door leaf opening provided with the sliding Schubbotzen corresponds, d. H. their depth or their diameter is matched to the dimensions of the thrust bolt. To lock the door leaf in the closed state is the push pin, which is arranged in the bottom area of the door leaf or the frame is axially displaced and thus brought into engagement in the opening, and a movement of the door leaf or its bottom-side section vertically prevented to the main level of the gate. This is the push pin ideally on the side opposite the door hinges side of the door leaf arranged on the door handle and lock are located.

The advantage of the invention is that due to the extension of the door leaf to the ground, d. H. the absence of a potential Trip hazard in the form of a door sill, this door can be used as an escape route is. In addition, when lifting the gate at least the bottom-side section of the door leaf relative to the surrounding door section set and thus a distortion of the door or a relative movement the door leaf to the gate prevented.

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

An advantageous development of the invention is that the Schubbotzen when moving in the opening next to the opening attached, in the motion cross section of the thrust bolt , protruding, pivoting Riegelelemen, z. B. a pawl, pushes or pushes to the side, this being formed with a latch-like End behind the edge of an abutment Hold the retaining strip on the door or gate segment and engage it. By the Pivoting and subsequent engagement of the locking element is a movement of the door leaf or at least its bottom side Section in the main plane of the gate itself prevented.

If the push pin is arranged in the door leaf and the associated Opening in the frame, then the locking element must also in the frame are located and reaches behind the retaining strip, which then on the door leaf is appropriate.

Advantageously, the door leaf or are the surrounding the door Frames with several of the above-described push pins and locking elements fitted. This allows the door leaf in several places be determined, and in particular in one of several sections assembled door leaf can be the push bolts and locking elements in the lateral lower and / or upper edge areas of the Door arranged to allow relative movement of each door leaf sections to avoid.

It is proposed that the axially displaceable sliding pins in the Frame and the corresponding openings in the door leaf to install. In this embodiment, it is possible to further described below Drive the pintle also on or in the area of Frames, i. to be accommodated in the gate.

Alternatively, the pintle also in the door leaf and the openings be mounted in the frame. The power supply, for example a power line for an electric bolt drive, can be suitably, z. B. with flexible cables, from the gate be guided in the door leaf.

To drive the pushers it is proposed that they be electromagnetically, z. B. via electric servomotors or with magnetic switches, hydraulically or pneumatically with hydraulic or pneumatic system, or are mechanically movable. A mechanical mobility of the thrust bolt, for example in the manner of a snap lock used in conventional doors take place, d. H. the pintle is moved by spring force and in the opening engaged. This may be the tip of the thrust bolt also hemispherical rounded to a latching and disengaging to allow out of the opening. Furthermore, it is the expert possible to attach any mechanical device that the Locking pin locked in closed position, as soon as the gate is raised becomes.

A further advantageous embodiment of the invention is that at the bottom of the door leaf more bolts in the main plane the door are vertically arranged, which may be displaceable, and, in the closed state of the door, in corresponding thereto Opening in the ground can intervene. One possibly for safety concerns desired or required additional displaceability The bolt can also be in the manner described above will be realized. In both versions, the bolts are used first to stabilize the gate when closed, d. H. that a movement of the door and the door perpendicular to its main plane is prevented. Such a movement, for example, under the Influence of strong wind pressure would permanently damage the Lead gates. Additional displaceability of bolts over one Drive can, especially in the area of the door, as an additional safeguard to serve against unauthorized use.

Advantageously, the length of the bolt is three to eight times the bolt diameter. With a suitable choice of material, in particular Metal or stainless steel, can be bolts with such a dimension record a maximum bending moment perpendicular to its longitudinal axis, without deforming under dessep influence.

In an advantageous embodiment of the invention is characterized by at least two of the vertically arranged bolts, the axially displaceable Pushers, the movement of Schubbotzen driven. This can the upper portion of the two pushrod formed as a rack be that with their vertical movement upwards, dje about gears and a steel band is deflected, the thrust pin from the belonging Opening pulls.

The Schubbotzen is advantageously against a compression spring moves, which is stretched by the movement.

Overall, when the gate closes the Schubbotzen moved back and the door is released. When you open the gate the jump Pintle, driven by the relaxation of the compression springs, back into the openings and lock the door.

At the same time to this process, the door segments through the Locking elements secured, which engage behind the retaining strips, as above described.

Overall, through these devices acting together the Locked door when opening the door and after closing for the door Use released.

To increase the safety of use of the gate is proposed that at the lower edge of the door a known electromechanical Sicherheitsfeiste is arranged, with which a strip-shaped Encoder is movable in the vertical direction against a spring force.

Should an object or person close when closing the gate located below the gate, the contact strip is replaced by the resistor the object moves relative to the gate and an electrical contact closed, which is connected to an automatic shutdown for the door drive is. Advantageously, the safety strip is led in three parts; d. H. that left and right at the gate and at the door respectively at the Lower edge of a bar is attached. In this case, the skilled artisan advantageous connect the strips electrically in a suitable way, that when triggered even a bar, the automatic shutdown reacts and shuts off the door drive. This is the safety guaranteed to stay under all three gate parts.

Another advantage is a device with the lowest Door leaf segment mounted part of the protective contact strip vertically is pivotable or liftable, far the door can only be opened slightly can, if the contact strip does not rest on the ground.

To lift the contact strip from the ground, a drive can be installed be, when opening the door, z. B. already when you press the Doorknob, is activated.

To be able to use the door also as a refugee way, she is with a equipped panic lock known to the expert. This allows Opening a locked door from the inside, for example by simply pushing down the door handle. This is allows the rapid evacuation of people from a building, even if they do not have a suitable key for the door.

At a proposed drive the vertically extending bolt on The bottom edge of the door leaf is recommended to be in operative connection to put with the door handle or the door lock. That means that at Operation 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, pull it upwards out of the openings in the floor and be inserted when closing.

The drive of the bolt can also be done here as described above, and it can, for. B. closed when opening the door, an electrical contact Be an electric or magnetic bolt drive sets in motion. In particular, a mechanical operative connection proposed between bolt and door handle, which consists of a Linkage exists, this at the height of the door lock with a Rack is fitted, which in direct engagement with a toothed Quadrant stands, which is about the doorknob about a horizontal Axis is pivoted. The linkage or connected to the bolt Push rod must be equal to the horizontal pivot axes, where the individual neighboring sections relative to each other are pivotable, also have a koaxiates joint, to allow the folding or folding process when opening the gate.

To prevent movement of the door leaf in the horizontal direction in the main plane of the gate is the door leaf and / or the vertical Frames equipped with hook-like devices, the corresponding molded projections on frames or door leaf in the closed State of the door behind. In particular, these hooks are in Range of bolts arranged to wind up the gap between Door leaf and frame, z. B. during opening to prevent.

A further advantageous embodiment of the invention is that on both narrow sides of the gate in the lower area a pressure roller is attached, which when closing the door on a centering or arresting curve accumulates in the lower part of the door frame is attached: This makes the gate and the door in the lower area merged, fixed their position and the bolts over the Centered openings.

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

Thus, the purpose of a precise centering is achieved, the flawless Function of the locking mechanism ensures is the height the centering or locking curve advantageously designed variably adjustable, so that can be readjusted at any time.
