Abstract

The door has panel sections with interlocking convex upper edges and concave lower edges. The upper hinge strip flap (8.1) is connected to the lower concave front side of the respective panel section (1). A quarter- circle shaped guard (9) fits into a slit (12) on the rear side of the convex front side (3) of the connected adjacent panel section.

Description

The invention relates to a sectional door consisting of individual articulated interconnected panel segments, the individual Panel segments each have a convex on their upper front broad side running cross-section and on its lower front broad side have a concave cross-section, so that as a result of the method of the sectional door along a guideway convex front face corresponds to a concave front face, and hinges to the inside of the sectional door articulated connection on the one hand and on the other hand to limit the gap of the panel segments are arranged to each other, with on the hinge Protective elements are formed on the opening between two angular panel segments in the axial direction close to the hinge hinge axis.

When changing from the closed position to the open position and vice versa pass through the individual panel segments of a sectional door arcuate guideway area, particularly in the arc area an angled position of the individual panel segments to each other he follows. To provide access protection for this section of track between to ensure the panel broad sides, these have in particular convex cross sections on their upper face and concave cross-sections on the lower broad face. One thus acts in an articulated connection of the panel segments convex front face with an underlying concave trained front broadside so that when walking of the arch results in a limiting gap between the broad faces. For the articulated connection of the panel segments are on the inside the gate hinge straps arranged so that the individual sections of the gate are hinged together. Especially in the area where the hinge straps are arranged, if the sectional door through the arcuate area of the guideway to be led. Openings that are also accessible before are secure.

A generic sectional door is from the European patent application 0 326 131 A2 and known from DE 196 00 553 C1. Out the publications are already known, especially for coverage to provide protective elements for the opening area on the hinge straps, wherein the protective elements are molded so that they after stand out from the sectional door surface, and on the lower hinge strap of the hinge are formed. Consequently results when the sectional door is in the curve area of the guideway arrives that the protective elements facing outwards in a row the curved path swings over from the upper articulated panel segment be so that the resulting opening is covered.

A major disadvantage of the known arrangement from the prior art Technology is that the protective elements from the surface of the closed Stand out. It follows that where the hinge straps are attached to the back of the sectional door, one each Row of these protective elements towards the inside of the sectional door protrude. These protective elements not only have a disruptive effect, but also also provide a target for objects standing on the back wall, that can get caught in it when the gate is opened.

It is therefore the object of the invention before the shown state of the Technology here to further develop a sectional door in such a way that it has a flat smooth surface on its inside, and on the other hand, it should be ensured that in particular the Hinges a firm bond with the front broad sides of the panels exhibit.

According to the invention, a partial task is solved in that on the upper one Headband tab, the lower, concave front edge of the panel segment is connected, a protective element in Shape of a quarter circle segment is formed, which in one Slit on the back of the upper convex front face of the articulated panel segment engages. The order of the protective element on the inside of the upper hinge strap brings significant advantages with it, in the form of a quarter circle segment trained protective element in the lowered The door protrudes into the sectional door surface and is therefore invisible is. If the sectional door is moved through the curved guideway, the quarter circle segment swings out of the sectional door surface and thus provides adequate access protection. The shutdown Sectional gate thus has due to the inventive design an inward-facing smooth goal wall surface, the Goal wall surface no longer offers the possibility that unwanted Objects can get caught on the back of the sectional door.

According to an advantageous development of the invention, the circular arc of the quarter circle segment under a game in the convex Cavity of the upper broad face can be swung in. Thus when the sectional door is lowered, access protection is complete from of the sectional door wall thickness. It is more appropriate Way between the hinge axis of the hinge band directly in the gusset the vertical leg of the quarter-circle arc segment and the upper hinge strap tab. The hinge axis the hinge band is thus integrated into the sectional door surface, so that even the hinge axis is not protruding and not is visible.

According to the invention, this solves the second subtask solved that in the area of the hinge straps in the upper convex and of the lower concave front face corresponding to the Convex and concave plastic molded parts adapted to the contour of the panel segment are arranged with screw channels. The integration of Plastic molded parts in the front broadside has a variety of Advantages that can be seen in the fact that, on the one hand, the one Sheet steel shaped panel segment especially in this area is stabilized, the attachment points not only on the molded Sheets are made, but on the embedded plastic molded parts. It also ensures that, in particular, to the Sticking points avoiding the fixed points.

The molded plastic parts are used to hold the sheet metal fastenings cutouts on the inside of the gate, which on the one hand Form seat for the bearing tabs and in the other hand the profiled curved convex or concave front and that the back forming sheet metal. In further training, the sheet metal edges are and folded back in the area of the recess and in the area the recess arranged overlapping. Be in the overlap area by means of the screw connection intended for the hinge tabs pressed together. This becomes a permanent connection especially the edge areas in this overlap area too put the screws in the provided in the plastic parts Screw channels can be screwed in.

According to a particularly advantageous development of the invention Area of overlap of the folded sheet metal edges in the recess of the concave plastic part between the folded sheet metal edges a lip seal arranged in the form of a strip seal. If the sectional door is lowered, the upper one comes inwards Edge area of the concave broad face to the system the lip seal and presses against it, making it airtight Closure can be achieved.

According to a particularly advantageous development of the invention the convex shaped plastic part has a transverse groove, in which fits the assembled hinge strap joint. So it will inward-facing hinge strap taken from the plastic molding. In a further development, slots are provided for receiving above the groove of the pivoted-in protective element. Thus it is achieved that the hinge band on the one hand with its circular arc segments and the plastic parts, on the other hand, interact with the sectional door, so that on the one hand the disruptive effect of the protective elements is avoided is by letting it into the sectional door surface, and that on the other hand high rigidity thanks to the plastic molded parts in the Berietch the front broad sides is reached.

1 shows a perspective view of two panel segments 1 and 2 of a sectional door, not shown, the are hinged together. Show, as from the figures 2, 4 and 5 can be seen in more detail, the individual panel segments 1 and 2 each have a convex surface on their upper front broad side 3 Cross section 4, with on the opposite lower front broadside 5 a concave cross section 6 is arranged. Thus, the kinematics of the panel segments standing opposite each other 1 and 2, also shown in FIGS. 2, 4 and 5 that due to the process of the sectional door along a Curved guideway, not shown, each a convex Front broad side 3 correspond to a concave front broad side 5. In particular, the gap during the pivoting process the mutually standing panel segments 1 and 2 between the front broad sides 3 and 5 kept the same during the pivoting process.

To enable the controlled pivoting process, is on the inside the sectional door a hinge 7 for articulated connection on the one hand and to limit the gap of the panel segments 1 and 2 otherwise arranged. At the top hinge strap tab 8.1 are Molded protective elements 9, the opening space 10, recognizable in particular in Figures 2 and 4, between two angular mutually standing panel segments 1 and 2 in the axial direction to the hinge axis Close the hinge strap 7. According to the invention on the upper hinge strap flap 8.1, which is concavely formed with the lower Front broadside 5 of the panel segment 1 is connected Protective element 9 molded in the form of a quarter circle segment. This Protective element 9, which is in the form of a quarter circle segment is activated when the sectional door is lowered into a slot 12 that is convex at the back of the top Front broadside 3 of the articulated panel segment 2 is arranged. This arrangement of the protective element 9 enables that the inward-facing back of the sectional door surface is smooth can be. Ultimately, only the screw heads are left before, as shown in Figure 5, this also in Countersunk holes can be inserted, so that a quasi smooth rear Sectional gate surface can be formed.

As can be seen in particular from FIGS. 4 and 5, the Arc 13 of the quarter circle segment under a game 14 in the convex cavity of the upper front broad side 3 can be pivoted. The hinge axis 11 of the hinge strap 7, shown in the figures 4 and 5, is directly in the gusset 15 between the perpendicular extending leg 15 of the quarter-circle arc segment and the upper Hinged strap tab 8.1 arranged. The hinge axis 11 of the hinge strap 8 is arranged such that it also in the Surface, i.e. facing the back of the sectional door is. The pivot point of the hinge axis 11 is thus in the rear wall of the Sectional door.

According to a particularly advantageous development of the invention in Figures 2 and 3, are in the area of the hinge straps 7 in the upper convex and the lower concave front face 3 and 5 corresponding to the contour of the panel segment 1 and 2 adapted convex and concave plastic moldings 17 and 18 arranged. In particular from the perspective representation of FIG. 2 it can be seen that in particular the panel segments formed from sheet metal 1 and 2 are shaped in their end regions so that they rests against the plastic molded parts 17 and 18 and these mounting. In an advantageous formation of the plastic molded parts 17 and 18, these have recesses 19 and 20 on the inside of the gate, the one hand a seat for the bearing bracket 8.1 or the lower one Form storage bracket 8.2, and in the other hand, the profiled curved convex or concave front 21.1 or 21.2 and the Sheet 22.1 or 22.2 forming the rear end.

As can be seen in particular from FIG. 2 and FIGS. 4 and 5 is, the sheet metal edges from the front 21.1 or 21.2 and the Back 22.1 and 22.2 folded in the area of the recesses 19 and 20, being particularly in this area of the recesses 19 and 20 arranged overlapping. Especially in this area of recesses 19 and 20 are the overlapping areas by means of the screw 23 of the hinge tabs 8.1 and 8.2 are pressed together connected. This results in a closed bond that serves as panel panel 1 and 2 forming sheets 21 and 22. The forming The cavity can be filled with hard foam.

A further development of the invention is shown in FIGS. 4 and 5 in the overlap area of the folded sheet metal edges in the recess 20 of the concavely shaped plastic part 18 between the folded Sheet metal edges arranged a lip seal 24 in the form of a strip seal. As from the interaction of the two panel segments 1 and 2 can be seen, especially the upper one pointing inwards Edge region 25, shown in FIG. 5, for contact with the lip seal 24. To accommodate the joint axis 11, in particular in Figures 4 and 5, the convex shaped plastic part 17 a transverse groove 26 into which the assembled Insert hinge strap 7 with its hinge axis 11. Here are how can be seen in particular in FIG. 3, in particular above the groove 26 slots 27 with, for example, molded pockets 28 Shaped recording of the pivoted-in protective element 9.

According to a further embodiment, shown in FIGS. 6 and 7 is the convex in the rear straight leg region Front broadside 3 a semicircular groove 29 for receiving the hinge axis 11 molded, with the convex curved area in the front the front broadside 3 a further groove 30 for receiving a lip seal 31 is molded. As especially from the representation of the FIG. 7 shows the plastic molded parts 17 and 18 are cuboid, with separate molded from plastic Pockets 28 in the region of the convexly curved region of the front broad side 3 are arranged, in which the protective element 9 engages.

According to the invention it is achieved that the hinge 7 on the one hand with its protective elements 9 designed as circular arc segments and the plastic parts 17 and 18 on the other hand with the sectional sound cooperate so that on the one hand the disruptive effect of the protective elements 9 is avoided by recessing into the sectional door surface, and that, on the other hand, high rigidity due to the plastic molded parts 17 and 18 in the area of the front broad sides 3 and 5 of the panel segments 1 or 2 is reached.
