Abstract

The closing element, in particular, the door comprises a number of individual panels (2), made from thermoplastic plastic with abutting longitudinal edges which are formed to match each other. The panels (2) are connected by elastic material strips (3) on just one side of the element.

Description

Closing element, especially gate

The present invention relates to a closing element, in particular a gate, consisting of a plurality of plastic panels 5, which are hinged to one another along their longitudinal edges, the closing element being movable between an open and a closed position by deflecting through a predetermined angle or by rolling up.

Closing elements of this type, in particular in the form of so-called roller shutters made of individual segments made of metal, wood or

.0 plastic, are known. In these conventional roller doors, the connection of the individual segments consists of hinges or guides and webs integrated in the segments. Such constructions are complex to manufacture and assemble and are still prone to failure.

L5 Even with small defects, the segments have to be replaced in pairs or have to be repaired at great expense.

The interconnection of the individual segments is only as good as the connection technology used. In the case of roller shutters in particular, a rotating shaft is required on which the 20 pull cables end. The rotating shaft must be installed above the roller door and ultimately determines the movement and the opening width of the door. The rotating shaft is subject to certain mechanical laws and is considered a wearing part.

5 It was an object of the present invention to provide a closing element which is as simple as possible and which consists of a large number of plastic panels, which is inexpensive both in terms of basic manufacture and in assembly, and by rolling up or preferably only by converting steer by a predetermined angle, for example 90 ° between an open and a closed position.

This object is achieved according to the invention in a closing element of the type defined in the introduction by the features of the characterizing part of claim 1.

The connection of the individual panels by means of elastic material strips, which form a kind of wear-free film hinge, enables extremely simple assembly. Regardless of whether the movement of the closing element is preferably only by deflection or rolling up, the apparent disadvantage that the closing element can only be deflected in one direction is negligible. A redirection in any two directions will hardly ever be important in practice.

Preferred embodiments of the subject matter of the invention are defined in the dependent claims.

The individual panels are preferably made of thermoplastic, e.g. made of polypropylene of the type Mono Pan (registered trademark), which in particular allows suitable edge closures to be easily attached to the panels.

The ends of the opposing longitudinal edges of the panels are preferably alternately formed as semi-cylindrical elevations or depressions.

In the case of thermoplastic synthetic materials with a honeycomb core, the edge finish is preferably carried out by deliberately fusing (in heat and under pressure) the honeycomb structure into solid material. Depending on the requirements for the tightness of the closing element, the end of the abutting edges can also have a triangular, rectangular or arbitrarily curved cross section. However, the designs with groove-like and comb-like interlocking of the edges are advantageous.

If thermoplastic material is used for the individual panels, the elastic material strip serving for the connection, preferably a Twin Tex fabric, can be melted onto the panels on one side of the panel

Closure element take place. This melting or melting is superior to gluing and is therefore preferable.

In the closed state, the interlocking of the abutting edges of the panels takes over the forces acting on the panels (e.g. when a load slips and is supported on the closed roller door).

The elastic fabric, e.g. the Twin Tex fabric, also melt in a strip shape or, in the case of panel manufacture, let every second panel manufactured have a top layer protruding and then melt the protrusion on the first panel.

The creation of the edge seal works for technical reasons practically without tolerance. When thermoplastic is used, the edge contours are made of PP material. The. with a door, naturally restricted movements and their loads are so small that there is no need for additional sealing in the form of filler materials. When closed, this version is splash-proof tight and has no conventional seal that could fail.

Each panel is preferably used on the right and left parallel to the side edge, e.g. a passage (hole) is made using a hot lance.

The panels on the right and left are guided by plastic glides in a rail that is designed according to the body to be closed.

Due to the prefabricated holes in the panels, wear pipes made of metal alloys are preferably inserted. These wear tubes are as long as the panel is wide.

For assembly, the panels for the locking element are stretched out flat on an assembly table. Auxiliary devices can now be inserted through the drilled holes to ensure that the panels are positioned relative to one another when the film hinge is welded on. After the film hinges have been welded on in one device, the auxiliary positioners are removed and the steel cables required for actuating the locking element are inserted through the completely manufactured door leaf on the right and left.

On the bottom door leaf panel runs a receptacle for the two steel cables, the ends of which are attached to this receptacle.

The two steel cables run completely through the door leaf and are well protected against dirt and moisture. This makes it possible to provide these ropes with permanent lubrication. An interchangeable spring sits on each side guide rail. The length-defined other end of the steel cables is attached to this on the right and left. At the end of the guide rails, for example, there is a rope reversing roller. The defined spring supports the force required to open and close the closing element when opening and closing.

The overall system of the closing element described above thus requires considerably less moving parts than a conventional door. A separate seal between the individual panels is completely eliminated. The force is distributed homogeneously across the entire width of the panel. Instead of a spring on the guide rail, a pneumatically, hydraulically or electrically operated single cylinder can simply be installed.

Embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing. It shows:

Figure 1 shows a vertical section of a section of a door according to the invention, consisting of a plurality of individual panels 2, which by means of interlocking

Longitudinal edges 2 ', 2 "lie close together. The individual panels 2 are connected to one another by means of elastic material strips 3 made of Twin Tex fabric (preferably by melting). Several strips 3 can be provided along a dividing line, or the strip 3 can be separate The panels 2 made of thermoplastic material (sandwich panels of the Mono Pan type) have edges which are closed on all sides (by fusing the edge zones) and are shaped to match one another along their longitudinal edges (semi-cylindrical contours as in FIG. 1) , or contour variants according to FIGS. 4 and 5).

The closing element is guided on both sides in a rail 4 (U-profile).

Parallel to the side edges, the panels have passages 5 (e.g. produced by hot lances), each of which is lined with a pipe section 6 made of abrasion-resistant material.

The passages 5 serve to accommodate auxiliary devices during the assembly of the panels to form the closing element and then to pass the pull cables 7, as also shown in FIG. 2.

The in the lateral guide rails 4th guided closing element is deflected in the ceiling by 90 ° (not rolled up), the individual panels 2 moving in the arch 8 approximately as shown in FIG. 7 (possible thanks to the elasticity of the material strips 3). The panels 2 lie against one another in the straight webs, as in FIGS. 1-5.
