Description

The invention relates to a multi-part protective cover for a winding roller of a door, preferably a roller door, a gate assembly and a method for mounting a multi-part protective cover.

The invention relates to the technical field of roller doors. Roller shutters serve to close door openings in walls or walls by means of a gate section which is flexible at least in sections and at least in one direction. The door leaf can be moved back and forth between an open position in which it releases the door opening, and a closed position in which it closes the door opening. For this purpose, the flexible door leaf can be wound onto a winding roller which is rotatably driven.

Side of the door opening side guides are arranged in which the door leaf is guided in a movement between the open and closed positions. Furthermore, the side guides in the closed position guarantee a planar alignment of the door leaf in a vertically extending Torblattebene. The winding roller and drive hangers are usually connected to the side guides to ensure stable cohesion and alignment. Thus, the trouble-free insertion of the unrolled from the winding roller door leaf is ensured in the side guides.

To protect the wound on the winding roller door leaf or to protect the winding roller when the door leaf is unwound, a protective cover is provided, with which the present invention deals.

So far, it has been customary to attach the protective cover for the winding roller of the gate on the side guides or on the bearing brackets of the winding roller. However, such constructions are very difficult to assemble because the Protective cover must be connected after attaching the roll-up door to the wall at a higher height with the construction. The exact and straight alignment with the roller door proves to be very time consuming and can not be done without additional machines by one or two technicians. Even a modular assembly at the intended location at high altitude is sometimes difficult.

A direct mounting of the protective cover on the wall causes problems, since a cover - depending on the size - is held by several technicians and must be aligned, while another makes the connections to the wall.

Against this background, the invention has the object to simplify the assembly work of the generic cover, so that the installation can be performed by two fitters without additional help or tools.

The invention in solution to this problem is a protective cover according to claim 1 and a gate assembly according to claim 12 and a method of assembly according to claim 14. Preferred embodiments are specified in the dependent subclaims.

The multi-part protective cover according to the invention is provided for a winding roller of a door, in particular a roller shutter. The protective cover has a wall-mounted retaining rail with a gutter profile. The gutter profile has a longitudinal extent in the transverse direction of the door and is open at the top. Furthermore, the multi-part protective cover comprises a hinged in the gutter profile guard. The protective cover comprises two side parts forming the lateral closure of the protective cover and a support bracket connecting the two side parts. The support bracket engages in the Gutter profile and is held to it. As a result, the guard is mounted in the support rail and is held by this by gravity. Another attachment is not necessary to hold the guard at the intended location. So a particularly simple, tool-free assembly of the components is possible. The protective cover can be pre-assembled separately - preferably on the floor - and hung in the retaining rail as a whole.

In a preferred embodiment, the retaining rail on a plant leg for attachment to the wall. This can be applied flat to a wall and bolted through holes provided with the wall. The flat contact of the plant leg on the wall surface allows a good force into the wall, which can safely absorb large loads in the vertical direction and tilting moments in conjunction with a suitable screw.

Preferably, an upwardly inclined bottom leg adjoins the plant leg. As a result, at least a part of the channel profile is formed. Due to the upward inclination of the bottom leg, in conjunction with the weight of the protective hood, the part of the support bracket engaging in the gutter profile is acted upon by a force in the direction of the contact leg, ie in the direction of the wall. As a result, an automatic feeder and increased stability is achieved. Appropriately, the transition between the plant leg and the bottom leg forms the lowest point of the gutter profile.

In a preferred embodiment, the bottom leg is straight. This forms a flat bottom and side surface of the channel profile and is inclined relative to the horizontal by an angle of at least 5 °, preferably 10 ° to 30 °.

According to a further preferred embodiment, the holding rail on a parallel to the plant leg aligned holding leg. In this case, close the planes in which the holding leg or the plant leg extend an angle of less than 5 ° or in particular run completely parallel. The retaining leg additionally prevents the support bracket from jumping out of the channel profile of the retaining rail. An outer surface of the support bracket associated with the support leg and / or the support bracket may be inclined away from the support leg by up to 5 ° in order to form an insertion bevel to facilitate fitting into the support rail.

The plant leg preferably connects to the plant leg opposite end of the bottom leg. The gutter profile thus has simplified upwardly open U-shape.

The upper end of the retaining leg can also form a support point for the support bracket on which this rests in the suspended state. In this way, the support bracket can be additionally secured against tilting away from the plant leg. The support point forms virtually a virtual pivot point for the support bracket. However, the engaging in the gutter profile part of the support bracket locks such a pivoting movement, so that the support bracket is securely held.

In a particularly preferred embodiment, the support bracket engages positively with a projection in the gutter profile. As a result, the support bracket is held in an intended position and orientation by the support rail. This positive positive guidance can not leave the guard automatically due to the weight.

Conveniently, the side parts laterally engage around the retaining rail and thus secure the protective cover in the longitudinal direction of the retaining rail. Particularly preferably, the length of the retaining rail is 95% to 100% of the length of the support angle.

In embodiments with an abutment leg, a bottom leg and / or a holding leg, the projection of the support angle lies, at least in sections, flat against one or more of these legs. In a very particularly preferred embodiment, the projection extends into a corner region, which is formed in the transition of two adjacently arranged legs.

In a very particularly preferred embodiment, the support angle is produced as an endless profile, in particular in extrusion molding. Such profiles can be finished in almost any length and cut to length as needed according to the installation situation. As a preferred material in this case a light metal, in particular aluminum is used.

The endless profile is in particular designed such that screws, in particular for fastening the side parts, can be screwed in at its end faces. The connection between the screws and the endless profile can be done directly - for example, as selbstscheidende threaded screws - or indirectly, for example by means of inserts or dowels.

Particularly preferably, the endless profile is designed as a hollow chamber profile. As a result, a significant weight and material savings can be achieved, while the advantageous mechanical stability is largely retained. The hollow chamber profile preferably has an upper, in particular flat wall, which simultaneously forms an upper-side outer surface of the protective cover. The lower end of the hollow section is through a lower wall formed, which can also form the projection for producing the positive connection with the retaining rail. The upper wall and the lower wall are connected by a plurality of vertically extending support webs. The distance between the upper wall and the lower wall decreases with increasing distance from the retaining rail.

At the bottom of the support bracket, a receptacle formed by an undercut is preferably provided, in which a sealing means for bridging the distance between the support brackets and the winding roller can be arranged. The sealant flexibly bridges the distance reliably and independently of the amount of rolled up on the winding roller Torblattmaterials. For this purpose, the sealing means has at least one height measured in the vertical direction, which corresponds at least to the distance between the receptacle and the winding roller.

The sealant inhibits the transfer of air and heat between the two Torblattseiten through the protective cover, especially in the closed state of the door leaf. Preferably, the sealing means is formed by a curtain or a short tarpaulin piece, which rests on the winding roller due to its own weight. Its length is dimensioned so that it can not be trapped between two systems of the door leaf, regardless of the direction of rotation of the winding roller.

According to a preferred embodiment, the multi-part protective cover further comprises a cover which is fixed to the support bracket and between the side parts. The cover, together with the support bracket and the side panels a multi-part enclosure for the winding roller. The cover may preferably have recesses, in particular for protruding aggregates of the door, such as the drive.

Preferably, the cover is formed with a sheet metal part, in particular a steel sheet. A steel sheet forms a high-quality and resistant outer shell of the protective cover. This can be bent several times in particular for encompassing the winding roller. The individual creases have an angle between 15 and 90 °. A sheet metal part also has the advantage that it can also be provided endlessly and cut to the required dimensions. Conveniently, it is then folded into the intended shape.

Preferably, the sheet metal part in the lateral direction of the door leaf (along the axis of rotation of the winding rollers) is formed divided into several parts. The sections have over the winding roller a correspondingly reduced length, so that they can be transported and handled easier in the disassembled state. To form the cover, the sections are fastened side by side on the support bracket. In addition, they may be interconnected by a connection arrangement.

The connection arrangement expediently has an inner frame and an outer cover strip. The frame follows the inner contour of the cover and stabilizes it in addition. The cover strip covers the parting line between the abutting sections. For fastening screw connections are provided which pass through the cover strip and at least one section and connect them to the frame.

According to a further embodiment, the cover can also be formed with one or more lamellae, preferably plastic lamellae. The plastic slats engage with a tongue and groove joint to form the covers into one another. They can be assigned to one Be held connector of the support bracket. In particular, the fins may be standard fins such as found in the construction of roller shutter applications.

Basically, combinations are possible in which the cover is formed divided both in the lateral direction and in the circumferential direction.

According to a particularly preferred embodiment, an engine cover is detachably arranged on the protective hood. The engine cover comprises the electric motor provided for driving the winding roller. For maintenance or repair purposes, the engine cover can be particularly easily solved by the guard. For this purpose, a tool-free releasable connection, in particular a latching connection is expediently provided.

Particularly simple, the engine cover can be formed as a one-piece injection molded plastic part. Alternatively, the engine cover is formed of several parts, for example, two half shells, which can be folded together for easier transportation.

The invention also relates to a door assembly comprising a wall with a door opening disposed thereon and a roller door for closing the door opening. In this case, the roller shutter on a two side of the door opening on the wall arranged side guides guided door leaf and a winding roller for rolling up the door leaf. Further, a multi-part protective cover according to the above description for covering the winding roller is provided. The protective rail of the protective cover is fastened to the wall above the door opening and the protective hood is suspended therein. The modular construction according to the invention allows a separate pre-assembly of the cover and independent thereof attachment of the support rail to the wall above the roller shutter.

In a preferred embodiment, the protective cover is not attached to the roller door, in particular on the side guides. Thus, the two components of the rolling door assembly from each other completely independent to assemble and disassemble. Any repairs - for example on the side guides - can be carried out without having to move or even dismantle the protective cover. This allows a particularly fast and smooth exchange of individual components.

Another aspect of the invention consists of a method for mounting a protective cover, in particular for forming a gate assembly according to the invention. According to the invention, the holding rail is first attached to the wall above the door and independently of this, the cover assembled. For this purpose, the two side parts are connected to the support bracket and optionally a cover. Then the protective hood is hung in the retaining rail.
