So It is inventively provided that a carrier an E-modulus of at least 70,000 MPa in the horizontal longitudinal direction having. With longitudinal direction is the direction of extension the carrier, which is larger as the transverse direction transverse to the direction of extension. It is particularly preferred if the inventive Carrier an E-modulus of at least 100,000 MPa in the horizontal longitudinal direction.

Further is an inventive gate wing preferably characterized in that the support is made of aluminum, unless the carrier already consists of a fiber composite material. Thus, a desired visual appearance and the achieved basic demanded corrosion resistance, at the same time the material costs for a gate stay in the usual frame. In addition, has a fiber composite material compared to a metallic material such as aluminum has the advantage that achieves a significantly improved thermal insulation can be.

Prefers is an inventive gate wing characterized in that the reinforcing profile on the inner Side of the vehicle with three sides of the vehicle communicates. This embodiment corresponds to that of one U-profile or C-profile.

In an alternative embodiment, it is provided that the reinforcing profile on the inner side of the carrier communicates with two sides of the carrier. in this connection So it would be a so-called L-profile.

Next the aforementioned profiles are also other alternatives Embodiments of the reinforcement profile possible. Should be emphasized at this point, a so-called Z-profile, in which the reinforcing profile with two opposite Side of the carrier is connected to the inside. Also possible is in addition to a one-piece executed a multi-piece reinforcing element. In addition, at this point, other types of profiles as T-profiles or I-profiles are called.

Prefers is that the reinforcing profile used essentially is flat, so that in cross-section opposite the width of the workpiece a small workpiece thickness is available.

Becomes a reinforcing profile for reinforcing the carrier attached to the inside, it is particularly preferred this reinforcing profile on the carrier by gluing, Fasten screws, rivets or clamps. By these ways of attachment the reinforcing profile is fixed to the carrier in conjunction, and so can the rigidity and strength total of the wearer.

In In a preferred embodiment it is provided that On the support connecting grooves are provided to at least one side of the support a panel, in particular of glass, to fix. In this way, the panel of at least one Side supported by the carrier, leaving a gate with a desired optical appearance can be realized can.

Indeed It should be emphasized that for attaching a panel is not necessarily appropriate Connecting grooves must be provided. A connection between a panel and a carrier may also be different ensured by joining the two elements together become.

Further a door is claimed, in particular a garage door or industrial door, the at least one gate according to a of the preceding claims. For example are several door sections or sections with straps and Panels arranged in such a way to an inventive To train goal. These gates or sections are to each other hinged. Possible in this context the connection of the individual sections with each other by means of hinges. In this context, however, is listed on the input Torarten referenced, which fall within the scope of the invention, namely Sectional doors, swing gates, lift gates, roller doors, sliding gates, overhead doors as well as other gate types.

Brief description of the drawings

following The present invention will become apparent from the accompanying drawings explained, with the figures listed here exemplary Embodiments of the present invention show.

1 is a cross-sectional view of a carrier transverse to its longitudinal direction for a gate according to an embodiment of the present invention.

2 and 3 show schematic representations of various sectional doors in cross section, in which sections of the invention are used.

4 shows a tilting gate, in which a gate according to the invention is used.

Detailed description of the preferred embodiments

In the cross-sectional view of 1 can be seen as the carrier profile 1 is designed as a hollow profile, which hollow profile is formed substantially rectangular. Furthermore, the carrier has two longer longitudinal sides, and two shorter transverse sides, wherein one of the longitudinal sides is extended beyond the dimensions of the hollow profile of the carrier. At these extensions connecting grooves are formed.

On the outer sides of the shorter transverse sides of the carrier connecting profiles are also formed, so that a panel 3 (see also 4 ) can come into contact with the connecting groove and the connecting profiles of the extended longitudinal side or the shorter transverse side.

On the inside of the designed as a hollow profile carrier are two reinforcing profiles 2 made of fiber composite material. These reinforcing profiles are designed as U-profiles, and with a shorter transverse side and a respective portion of the two longitudinal sides in conjunction. As shown, the reinforcing profiles 2 attached by gluing to the inside of the carrier.

Below are in the 2 and 3 exemplary door types listed in which a gate with individual sections according to the invention is used. However, it should be expressly understood that a gate according to the invention, as mentioned above, can be used in a number of other gate types, without departing from the spirit of the invention. By way of example and not by way of conclusion, revolving gates, lifting gates, rolling gates, sliding gates and tilting gates are mentioned here.

In 2 a gate is shown, in which the gate member according to the invention can be used. The gate consists of several gate sections (sections), which close the height LH of the entrance in the closed state. The door members are pivotally connected to each other by means of hinges. When opening, the door leaves in a track upwards, and is placed behind the fall in the room on the ceiling. The insertion depth ET here essentially corresponds to the height LH of the input.

3 shows another alternative embodiment of a sectional door, in which a gate according to the invention can be used. This in 3 Tor shown is used when a low insertion depth ET is desired. Also in this embodiment, the door members are hinged, but the hinges are mounted so as to allow almost vertical stacking of the door members in the open state of the door. Due to the almost vertical stacking of the individual door elements behind the fall, the space in the depth of the room behind the goal is hardly affected. This type of door is particularly suitable when the room depth behind the open door for fixtures such. As crane runways, lifts in garages, high-bay warehouses or for forklift trucks with high goods is needed.

Next poses 4 a tilt gate, in which the gate according to the invention can be used. In particular, there are several adjoining carrier profiles 1 and panels 3 to recognize.

In the illustrated embodiments ( 2 . 3 and 4 ), the support structure according to the invention is used to significantly reduce the deflection of a gate member over those of the prior art. Because of the increased rigidity, heavy panels carried by the beams can also be used without incurring disadvantages in the storage of the door members in the open or closed state. If the carriers sag due to the heavy weight of the panels, the sliding action could be adversely affected, or, for example, a panel could come off the bracket of the carrier as it deflects. Overall, however, the present invention contributes to the appearance of a gate being improved if it does not bend.

So serves the gate according to the invention In addition, with the same degree of operational reliability, the flexibility regarding the possible panels to be used (material, Weight, ...) over the prior art.
