Problems solved by technology

Another disadvantage of this structure is that the entire sheet is extruded, so the deformation of the material is limited
In particular thin slices are more expensive to process, thereby increasing costs
In addition, in order to change the structural shape of the sheet, a new extrusion die must be manufactured accordingly, which may increase the cost
In addition, due to the inevitable small and clearly visible processing traces left in the direction of extrusion, the known plastic sheet is limited by the processing method, and its transparent area cannot be as transparent as glass

Embodiment Construction

[0035] according to figure 1 The high-speed industrial door 1 shown has a door leaf part 2 which is accommodated in a door frame 3 and guided on both sides. The lateral guide in the door frame 3 has a vertical portion 31 in the area of ​​the door opening and a spiral portion 32 in the area of ​​the lintel of the door opening. Both sides of its door piece 2 have hinge band 21, and it is as figure 2 As shown, there are a plurality of flexible hinges 22 connected to each other on its side. They are guided in lateral guides by means of guide wheels 23, wherein for the sake of clarity in figure 2 Only one guide wheel is shown. The components guiding the door element 2 and the functions of these components are basically the same as those disclosed in DE 199 15 376 A1 and will not be described in detail here. Furthermore, its flap part 2 has a bottom-side end closure part 24 .

[0036] As shown in the figure, the door piece also includes two types of reinforcement structures, ...

Abstract

The door-panel (2) covering the door opening has a hinge strap (21)on both sides, with hinge members (22)which run by means of rollers (23) along side guides, The door panel has reinforcement profiles (25,26) and a flexible hanging (27) fixed to each reinforcement profile running crosswise to the side guides, and extending over the door panel to join two hinge members. The hanging is in several segments (271,272) .

Description

technical field [0001] The invention relates to an industrial door operating at high speed, with a leaf part covering the door opening, on both sides of which comprises a hinged strip with a plurality of mutually connected flexible hinges, which are guided in lateral guides by means of guide wheels , so that the door pieces are guided without contact. Background technique [0002] The high-speed rolling door actually known has a winding of the door leaf element above the door opening. Suspensions made of soft PVC or similar soft material, such as in the indicated roll-up doors, are wound up in the usual manner onto the roll-up shaft and can be unrolled in order to close the door opening. Since rolling doors of this type are inexpensive and, moreover, the door leaf parts formed by the suspension elements are completely or partially transparent, they have proven to be advantageous in practice and are generally used. For example, the driver of a forklift can also see clearly ...
