DE8800956U1 - Joint for segmented covers - Google Patents

Abstract

Pivot for a covering which can be moved along a curved path and is divided by the pivots, transversely with respect to the direction of movement, into segments which can be swivelled relative to one another about the pivot axis. The end faces of two adjacent segments are in each case formed in such a way that the gap present between these does not exceed a predetermined maximum value during the swivelling of the segments. The construction according to the invention with a two-part segment shell and a plastic supporting strip which bears a seal and is in each case arranged on the end faces of the segments permits the use of an efficient manufacturing process, the hollow space of the segments preferably being filled with a PUR foam system. <IMAGE>

Joint for segmented covers

The invention relates to a joint according to the preamble of claim &Idigr;.

Known covers of this type, which are used as sectional doors for garages, for example, are rolled out of the opening area on a curved path when opened, and are thereby moved from their vertical position to a horizontal position. With the known joints between the segments of these covers, a relatively wide gap is created between the segments when the individual segments transition into the curved path, which closes again when the opening area is closed. This creates a significant risk of injury for the user if they accidentally reach into such a closing gap during the closing process. This risk of crushing also exists with covers of this type that are operated automatically or even remotely.

The invention is based on the object of creating a joint according to the preamble of claim 1, in which any risk of injury is safely excluded.

This object is achieved according to the invention with the features specified in the characterizing part of claim 1,

Due to this design of the end surfaces of the segments and the arrangement of the pivot axis at a distance from the convex end surface, the gap between the end surfaces can be kept practically as narrow as desired when the segments are pivoted, so that any risk of crushing is avoided by making it impossible for a finger to penetrate the gap.

The hinges of the joint are easy to assemble because the convex end surface of one segment is curved approximately cylindrically, with the cylinder axis coinciding with the joint axis arranged on the inside of this segment.

Preferably, the radius of curvature of the convex end surface of one segment corresponds at least to the distance between the joint axis and the outer surface of this segment. The hinge can then be designed so that the joint axis lies directly on the inside of the segment with the convex end surface.

The end surface of the other segment is expediently designed to be concave, whereby in order to keep the gap between the two end surfaces constant over the entire pivoting range it is advantageous if both end surfaces are concentric with the joint axis.

The cover wings according to claim 8 ensure that even on the inside of the cover, on which the hinge axis is arranged, any risk of crushing due to

Il ·

of a ai.h B^ ^1-1 I ieftcnden cavity safely excluded

To prevent water, dust and the like from penetrating the inside of the cover, a seal can be fitted on one of the end surfaces, which is arranged, for example, close to the outer edge of the end surface and seals the space behind it even when the segments are fully pivoted and ensures that the end surfaces continue to overlap at their opposite edge sections when the segments are fully pivoted.

The invention is explained in more detail below using the description of an embodiment with reference to the drawing, which shows a sectional view of the joint.

The illustrated, adjacent segments 1 and 2 of a cover, for example of a garage door, are arranged vertically one above the other in a plane when the cover is in the closed position. A lower end surface

4 of segment 1 is opposite an upper end surface 5 of segment 2. Both end surfaces are cylindrically curved and run concentrically to a joint axis 3, whereby a largely constant distance d is maintained between the end surfaces 4 and 5, which should be at least 1 mm.

The drawn mutual position of segments 1 and 2 is ensured by a plurality of hinges 11, which are connected to hinge arms 9 and 10 along the end surfaces 4 and

5 are fixed at a mutual distance on the inside of the segments 1 and 2. Each hinge 11 has a longer hinge arm 9 and a shorter hinge arm 10, the longer of which extends from the hinge axis 3 to the upper segment 1 and is mounted on it, while the shorter arm 10 is mounted on the lower segment 2. As

As can be seen from the drawing, the hinges 11 are designed and attached to the segments 1 and 2 in such a way that the pivot axis 3 is arranged on the inside of the lower segment 2 and at a distance from the upper edge of this segment that corresponds approximately to the distance between the hinge axis and the outside of the segment 2. The distance between the hinge axis 3 and the upper edge of the lower segment 2 could of course also be chosen to be larger, whereby care must be taken that when the segments are fully pivoted (shown in dashed lines in the drawing), no gap is formed between the end surfaces 4 and 5.

The two end surfaces 4 and 5 are rounded at their outer edges 7 and 8, which are located on the outside of the cover. Furthermore, the outer edges are spaced apart by a distance e, which is dimensioned such that it is not possible for a fingertip to become trapped, for example at least 4 mm.

When segments 1 and 2 are pivoted towards each other when the cover enters the curved path in order to reach the pivot position shown in dashed lines in the drawing, the end surface 4 of segment 1 moves in relation to the end surface 5 of segment 2, partially releasing the end surface 5, without the width d of the gap between the end surfaces exceeding a permissible maximum value.

As the drawing further shows, when the segment 1 is pivoted in relation to the segment 2, a gap 6 is created between the hinge arm 9 and the inside of the segment 2, which disappears again when the segment is pivoted back into the position shown in the solid line in the drawing. In order to prevent a person who is standing inside the space to be closed while the cover is being closed from entering this gap,

can grip, cover wings (not shown in the drawing) are attached to the side edges of the hinge 11, for example, which close off the gusset space 6 to the outside.

On one of the end surfaces U or 5, advantageously on the end surface H near its outer edge 7, a seal, also not shown, can be attached, by means of which the gap between the end surfaces ¹ \ and 5 remains closed in any position of the segments.
