Description

The invention relates to an automatically driven gate, as for example in the company brochure garage doors and entrance gate drives Hörmann KG sales company with the printing notice "Stand 05.2014 / Druck 05.2014 / HF 85945 DE / G.xxx", available, inter alia, via the Internet , described and shown.

In particular, the invention relates to automatic garage doors.

In the entire construction industry, good thermal insulation is a hot topic. Because of this, gates have also been improved more and more in terms of thermal insulation in recent years, which is associated in particular with an improvement in the tightness of the gates. While a few decades ago many gates were provided with vents, nowadays greater importance is attached to the best possible tightness to prevent heat loss, especially when a space to be closed by the door is arranged adjacent to heated rooms.

This improvement in tightness, however, results in e.g. to the problem that, depending on the weather and temperature in a room in which vehicles are parked and moisture is introduced accordingly, it comes to damp walls, which also leads to mold, e.g. in garages, can lead. There is also the problem in tightly closed garages that undesirably high gas concentrations of noxious gases could arise. There is therefore a desire to be able to ventilate the space to be closed by the gate.

There were a few years ago in the market, e.g. from the company BeluTec, sectional doors in which, in otherwise closed position, the uppermost panel could be moved into a special ventilation position. However, these gates are complex in construction and in particular quite expensive if they are to be automated.

In the above-mentioned company brochure, however, it is proposed to design the drive device of the door so that an additional opening height can be programmed for ventilation. If the user gives the command to move the door to this ventilation position, the door leaf remains slightly open. For sectional doors, the uppermost panel is tilted inwards so that air can enter and exit at the top. Also down between the floor, against which seals a closing edge of the door leaf in the closed state, and the closing edge remains a Gorspalt through which also air can circulate.

This solution is very simple and practical to implement with each driven gate by simply a second opening position, eg a second opening height is programmed so that the door leaf opens only a crack. There is also the possibility of mechanically securing a door leaf in the ventilation position, as in the DE 10 2014 110 755 B3 described and shown. Further, by forming both an upper nip and a lower nip, air circulation is improved.

Nevertheless, this possibility has not yet been universally accepted in practice. This is to be improved by the invention.

For this purpose, the invention proposes a gate according to claim 1.

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

According to one aspect, the invention provides an automatically driven door having a door leaf movable between an opening end position and a closing end position and a drive device for driving the door leaf, the drive device being adapted to selectively move the door leaf to a venting position between a closing edge of the door leaf Door leaf and a fixed area against which the closing edge abuts in the Schließendstellung remains a Torspalt, wherein on the door leaf, a gap cover for covering the door leaf is arranged, which is at least partially movable relative to the closing edge of the door in the opening and closing movement direction.

In particular, an improvement of an automatic door with ventilation position in terms of safety and / or cleanliness is achieved without having to make expensive special constructions on the drive device or the door.

It is preferable that the gap cover has through holes for venting.

It is preferred that the gap cover comprises a gap cover strip, in particular of a rigid material, which is displaceably mounted in a displacement guide on the door leaf in the closing movement direction.

It is preferred that the gap covering strip has a grid, in particular a plastic grid.

But it is also possible that the cover strip is at least partially made of a metal sheet, in particular sheet steel or aluminum sheet, and / or of a metal mesh, in particular steel mesh or aluminum mesh formed.

It is preferred that the gap cover has a flexible cover element made of a flexible material.

It is preferred that the cover element is at least partially formed from a network of flexible material, in particular a textile material or plastic material.

It is preferred that the gap cover has a stiffening strip extending substantially along the closing edge for stiffening the flexible covering element.

It is preferred that a supporting device for supporting the stiffening strip is provided fixedly on the door and / or that the stiffening strip is supported on both sides in the area of a door leaf guide, at least in the ventilation position.

It is preferred that a clamping device is provided for exerting a clamping force on the flexible cover element.

It is preferred that in the region of a free edge of the cover a closing edge safety is provided, which is designed to detect an obstacle in the door path during a closing drive and to stop and / or reversing the drive device when an obstacle is detected.

The gate is, for example, a sectional door, a garage door, a swinging gate, a tilting gate, a single-leaf overhead gate, a lifting gate or the like. The drive device is preferably a garage door drive, a tow gate drive, a shaft gate drive, a direct gate drive and / or a chain gate drive.

It is preferred that the gate gap in the venting position have a nip width of 10 mm to 500 mm, preferably 30 mm to 450 mm, most preferably between and including about 300 mm and including about 400 mm.

Preferably, at least one end edge of the cover is movable relative to the door leaf by at least one amount corresponding to the door gap width in the ventilation position. Preferably, the end edge of the cover is movable by 1 mm to 40 mm more than the gate gap width in the ventilation position relative to the door leaf. Preferably, the relative movement between the end edge of the cover and the door leaf is limited to the specified amount by at least one stop.

An idea of a preferred embodiment is based on the finding that a Gorspalt, which remains open in the ventilation position, especially at the bottom of the ground, may have the disadvantage that dirt or small animals can penetrate into the space to be closed. Another idea of another preferred embodiment is based on the fact that the gap left open can also give rise to concerns of a user with regard to possible burglaries.

Preferred embodiments therefore provide a cover for the Torspalt, which is active in the ventilation position and covering the Torspalt.

By covering the gate gap, the penetration of foreign bodies such as e.g. At least reduce leaves, dirt or spray at the lower gate gap. In addition, the penetration of small animals, in particular martens, but also of cats or mice or of - depending on the size of through holes - larger or smaller insects and spiders, prevent. A cover of the gate gap also offers a better deterrent effect against burglary attempts than releasing the Torspaltes.

To further improve the burglary protection according to one embodiment, a rigid cover strip, in particular at least partially made of plastic mesh, is provided, which is mounted in an opening and closing direction displaceably on the door leaf in the region of its closing edge. For example, a sliding guide for the cover strip is provided on the door leaf.

The cover strip is preferably so freely movable in a sliding guide on the door leaf to a limited extent that the resulting gap in the ventilation position between the closing edge and opening boundary is completely or at least largely covered. The sliding guide allows only a limited displacement, so that on further opening of the door leaf, the cover is moved in the opening direction to release the door opening.

The more rigid and robust the cover is designed, the more burglary protection can be improved. Therefore, covers made of metal, for example, at least partially formed of a metal sheet or a metal grid, conceivable. However, for more rigid or sturdy or heavier covers, an approach to an obstacle can cause problems. A closing edge safety device attached only to the door leaf might not be able to cover the cover to an obstacle. Therefore, it is preferred in such Torkonstruktionen the cover form such that a movement of the cover a Requires force that does not exceed a force of 400 N in the dynamic case and a force of 150 N in the static case. This can preferably be achieved with lightweight plastic meshes or with textile net designs.

In particular, in the case of the more robust covers, e.g. made of metal or heavy plastics, could be provided in one embodiment, a closing edge safety instead of the closing edge of the door leaf or in addition to an attachment to the closing edge of the door leaf on the cover. For example, could be provided at the free edge region of the cover, a leading photocell or rubber trim.

In the simpler and therefore preferred case, the cover is as lightweight and / or free-moving and / or flexible, so that driving the cover on an obstacle or a person does not cause damage or injury.

Accordingly, in a further embodiment of the invention, the cover at least partially or for the most part made of a flexible material, such as textile material, a network or a flexible plastic.

The cover is preferably provided with through openings, so that an air circulation for ventilation is possible. The size of the passage openings is preferably chosen such that the penetration of smaller animals such as, for example, martens, cats, mice and / or larger spiders is prevented or at least made more difficult.

Embodiments of the invention are explained below with reference to the accompanying drawings. It shows:

5 a view similar to 4 wherein the door is moved to a closed position; and

6 a front view of a portion of the panel and the cover according to the further embodiment.

In the 1 to 3 is a first embodiment of an automatic gate 10 shown. It is in 1 for example, designed as a garage door gate 10 in a ventilation position from outside on a garage 12 seen in 2 the gate 10 in the ventilation position from the side in the garage 12 represented and in 3 a detail area near a main closing edge - closing edge 14 - the gate 10 in the ventilation position 16 shown.

The gate 10 is shown in the illustrated embodiments as a sectional door. However, the goal may be 10 be designed in a different gate construction, for example as a lifting gate, tilt gate, pivot, single-leaf overhead gate or the like.

The gate 10 has a door leaf 18 , a guide 20 for the door leaf, for example, formed on a frame 22 and further, for example, with guide rails 24 provided, and a drive device 26 for driving the door leaf 18 on.

The drive device 26 in particular has a door drive 28 , possibly provided with an external gate control (not shown). The door drive 28 can be in any one for the respective door leaf 18 be designed suitable construction. In the illustrated embodiment according to 2 is the door operator 28 as a towed drive with a drive rail 30 and a drive head 32 shown. In the drive rail 30 is driven by a motor in the drive head 32 a driving carriage (not shown) reciprocally driven to a driving rod 34 on the door leaf 18 docked, the door leaf 18 to drive between an opening end position and a closing end position. For more details on the design of the door drive is on the above-mentioned company brochure and expressly to the DE 10 2014 110 755 B3 directed.

Instead of a tow drive, the door drive could 28 also be designed as Wellentorantrieb or Direkttorantrieb, as a chain drive or the like.

The door leaf shown as an example in the embodiments shown here 18 is a sectional construction with several hinged panels 34 fitted.

The drive device 26 is formed such that in addition to the opening end position and the closing end position also an additional Opening height L _H can be programmed as the ventilation position 16 can be approached.

For example, it may be provided for this purpose a remote control (not shown), which is provided with a plurality of buttons, wherein the pressing of one of the buttons, the ventilation position 16 drives, so that the drive device 26 the door leaf 18 in the in the 1 to 3 illustrated ventilation position 16 moves.

In this ventilation position 16 has the closing edge 14 a predetermined distance L _H from a counter-closing edge on a fixed unit, such as the floor 38 , This is in the ventilation position 16 between the closing edge 14 and the stationary unit 36 or the counter-closing edge a Torspalt 40 educated.

In the example shown, the closing edge 14 at the bottom panel 34a educated. In the ventilation position 16 is the topmost panel 34b in the lead 20 already a piece in the interior of the garage 12 tilted into it, so that even at the top of the door opening an upper gate gap 42 is trained. Through the gate column 40 . 42 can in the ventilation position 16 Air circulation takes place to the garage 12 to keep drier and / or free of questionable gas concentrations or the like undesirable room conditions.

In the area of the closing edge 14 is the door leaf 18 with a gap cover 44 provided to the gate gap 40 in the ventilation position 16 cover.

The gap cover 44 is at least with its lower free edge in the opening and closing movement relative to the door leaf 18 movable, as indicated by the arrow 46 is indicated.

In the in the 1 to 3 illustrated first embodiment of the gap cover 44 has this one in a displacement guide 48 on the door leaf 18 slidable with the door leaf 18 Connected cover strip 50 on.

The cover strip 50 is formed according to an embodiment completely from a grid, in particular from a plastic grid. In the illustrated embodiment, the cover strip 50 with a frame 52 equipped in which a grid 54 is included. The frame 52 and the grid 54 can be made of the same material or of different materials. In particular, frames are 52 and grid 54 Made of a lightweight plastic.

The shift guide 48 can be designed differently. For example, on the back of the door leaf 18 a box 56 formed, in the cover strip 50 when completely closing the door leaf 18 can be moved into it.

Next is the relative movement 46 between cover strip 50 and gate leaf 18 through mutual attacks 58 limited, leaving the door leaf 18 for a complete opening the cover strip 50 with takes up.

The weight of the cover strip 50 as well as the sliding guide 48 are designed such that during a closing movement of the door leaf 18 upon impact of the outstanding cover strip 50 a maximum of 400 N dynamic force and a maximum static force of 150 N on the obstacle.

In another - not shown - embodiment, the cover strip 50 made of sturdier material, with a closing edge safety in the region of the free end edge of the cover strip 50 is provided. For example, the cover strip 50 formed as part of a leading photocell.

The following is based on the representation of the 4 to 6 a second embodiment of the gap cover 44 explained in more detail.

The gate 10 in the embodiments of 4 and 6 is up to the formation of the gap cover 44 formed immediately to the previously explained gate.

In the second embodiment according to the 5 to 6 is the gap cover 44 instead of in the sliding guide 48 sliding cover strip 50 with a flexible cover 60 made of a flexible material 62 Mistake. As a flexible material 62 is preferably a network 64 intended. The network 64 is made of textile materials or plastic thread and / or metal threads.

The flexible cover element 60 has an upper bar 66 and a lower bar 68 on, for example, in piping on the edges of the flexible material 62 are included.

At least the bottom bar 68 is designed so long that it has both ends in a vertical guide rail 24 for the door leaf 18 intervention. The lateral vertical guide rails 24 thus act as a support means for supporting the flexible cover member.

As in 4 shown, then, when the door leaf 18 in ventilation position 16 the procedure is network 64 clamped by the weight of the lower bar. The flexible cover element 60 thus covers the gate gap 40 from. Will the door leaf 18 on the other hand, move into the final position, as in 5 is shown, then moves the lower bar 68 relative to the closing edge 14 of the door leaf 18 , wherein the flexible material 62 and especially the network 64 dodges to the side. Will the door leaf 18 about the ventilation position 16 In addition, in the direction of the opening end position and moved back, it takes each of the flexible cover 60 With.

The flexible cover element 60 provides even lower resistance when driving on obstacles than the cover strip 50 represents.

Through the gap cover 44 According to the two embodiments explained above, the penetration of leaves or other unwanted particles as well as the penetration of animals in the ventilation position 16 avoided.

The cover strip 50 and the network 64 are with through holes 70 provided, so that continues the good ventilation through the lower gate gap 40 and the upper gate gap 42 given is.
