Abstract

The hinge joint between two plate elements (10, 20) comprises a cover or sealing profile with at least one side element (3, 4) which is elastically pressed against an edge or a side of a seating groove (22). The length of this side element in the cross section of the cover or sealing profile is greater than the maximum pivot trajectory of the two plate elements relative to one another.

Description

The present invention relates to a hinge connection with a first plate part, which has a first edge surface and with a second plate part which has a second Has edge surface, the two plate parts connected to each other via a hinge are, the hinge axis substantially parallel to the edge surfaces, but outside the middle planes of the plate parts runs, and with an anti-trap profile, which on a of the edge surfaces is anchored and with a clamp protection leg in a receiving groove extends into the opposite edge surface.

Such a hinge connection is known for example from EP 1 072 750 A1. This Document describes a sectional door, the individual sections of which are formed by plate parts are connected to each other along adjacent edges via a hinge are. The hinge axis lies outside the central planes of the plates and can e.g. B. in the plane one of the outer surfaces of the plates or outside of the plates substantially parallel run to the edge surfaces. The edge surfaces are not flat surfaces, but generally highly structured. In the known example, the edge surfaces in the profile are like this trained to have a concave on one side and a convex on the other Describe a circular arc, the center of which is formed by the hinge axis. Radial within the convex surface, the one edge surface also has an anchoring groove, in which is anchored the anchoring section of a profile element, which is with a Anti-trap leg extends out of the anchoring groove and its course approximately follows the convex shape of the edge profile, the opposite edge surface being a has corresponding receiving groove for the anti-trap profile, at least one of the Groove walls form the aforementioned concave surface.

When the two plate parts are aligned in parallel essentially in one plane, sit the two opposite edge surfaces essentially on each other, the edge surface having a convex profile forms a projection and which forms the concave profile having edge surface forms a recess in which the opposite projecting Edge area is recorded and this recess is also sufficiently dimensioned, to additionally accommodate the protruding leg of the anti-trap profile. At the Swiveling the plate parts out of the parallel alignment around the hinge axis the sections of the edge surfaces located away from the axis move apart. The leg of the anti-trap profile protruding from one edge surface has the purpose, the resulting gap between the edge surfaces on the hinge axis largely to seal away the opposite side of the plate parts or at least not to allow it to grow above a predetermined tolerance level so that there is no danger; that a person accidentally or deliberately reaches into the opening gap, so injuries Avoid fingers that when swiveling the plate parts back into a parallel Would otherwise threaten alignment.

The protruding leg of the anti-trap profile is essentially rigid and immobile and its outer surface only follows the convex shape of one edge surface, so as to cover the swiveling range of the concave edge surface, that of the maximum swiveling of the two plate parts can arise relative to each other.

The present invention relates generally to a hinge connection between two plate parts which can be pivoted relative to one another and have the features mentioned at the outset, sectional doors are primarily considered as an area of application, but without the present invention is intended to be limited to this. The term "plate part" is also in this respect to be interpreted widely and of course also includes frame elements, slats or the like, as long as they have the basic structure of plate parts only in the connection area, d. H. two edge surfaces pivotable relative to one another with a hinge axis which is arranged outside an imaginary central plane of the respective plate plane, so that a corresponding gap at all between the mutually movable edge surfaces forms, which is to be kept closed by an anti-trap or sealing profile.

In the following, however, the present invention is described only with the aid of sectional doors, however, as already mentioned, the invention also applies to other fields Can be found.

Conventional sectional doors consist of individual panels or panels, which are typically have a thickness between 20 and 40 mm and their outer surfaces made of plastic or metal are made and the interior of which is filled with an insulating material. These plates but can also have viewing windows and then consist essentially of a frame structure with glass or plastic panes held in it.

The hinge joints in the area of adjacent and adjacent edge surfaces two panels are arranged, are usually on the inside of corresponding sectional doors arranged, and the hinge axis usually runs outside the plate cross-section, but possibly also in the plane defined by the inner surface of the panels. It is assumed that the individual panels when opening or closing a corresponding one Swing sectional doors towards each other inwards. The outer surface the panel is then at a distance from the hinge axis which is at least the thickness of the Panels corresponds and is usually about 5 to 10 mm larger than the thickness of the panels. The pivoting angle of individual segments or panels of a sectional door can be up to approximately Be 90 ° so that the edges of the plate lying in the area of the outer plate plane can move apart on a circular arc, the maximum length of which is about π / 2 x D , where D is the distance from the hinge axis to the outer surface of the plate, that is corresponds at least to the thickness of the panels or panels. In practice, there can be distances occur between the outer edges of the plate parts, which are on the order of 30 to 60 mm.

The edge surfaces of some conventional sectional doors generally face that one side has a trapezoidal recess, in which the bottom of the trapezoid is about half-filling gasket is inserted, while the other edge surface one corresponding, but smaller in cross section, trapezoidal projection that in turn also has a recess for receiving a seal, the edge of which over the outermost edges of the trapezoidal protrusion protrudes, protrusion, recess and seals are dimensioned so that when the sectional door is closed, i.e. in parallel Align the plates, the seals are pressed into tight contact with each other and the plate edges just outside of the projection and the recess come into contact or through the sealing engagement at a short distance being held. A corresponding prior art is shown in Figures 1 and 2.

As can be seen in particular with reference to FIG. 2, the swiveling apart results in the a very large gap between the two plate parts, which does not offer any protection against pinching.

In the already described EP 1 072 750 A1, the pinch protection is ensured by that on the one hand the trapezoidal projection on its outside facing away from the axis convex shape and overall significantly increased and that the trapezoidal Recess deepened accordingly and concave on the side facing away from the hinge axis is formed, the gap still remaining thereafter by a on its outside also convex and following the course of the convex protrusion anti-pinch profile is covered.

In concrete terms, however, this means a considerable redesign of the conventional edge profile. In particular, according to this prior art, it is not possible to use existing sectional Retrofitting an appropriate pinch protection, because the edge surfaces in should be trained accordingly.

Compared to this prior art, the present invention is based on the object a hinge connection for hinge-connected plate parts, in particular for the panels of sectional doors, too sharp, which also with existing panel parts or sectional doors that have no pinch protection, can be retrofitted and which one offers sufficient protection against jamming.

This object is achieved in that a corresponding anti-trap profile on the one hand Has anchoring part with which it is anchored to one of the edge surfaces, and on the other an elastically movable profile leg connected to the anchoring part has, which is received in a groove of the opposite edge surface and under resilient bias against an inner wall or the edge of this groove and thereby a Length has at least the length of the maximum swivel arc of the hinge axis Corresponding groove edge corresponds.

This ensures that the at least one leg of the anti-trap profile, which is connected on the one hand to the anchoring part of the one plate part, always on the Wall or outer edge of the opposite groove is in contact, even if this groove having plate part is pivoted relative to the first-mentioned plate part, this Anti-pinch leg is of sufficient length to completely cover the resulting gap to bridge, because its length is at least that of the groove edge Swivel arc corresponds and since the anti-trap leg is always under elastic pretension abuts this groove edge or the associated groove wall.

Since the anti-trap leg and the entire anti-trap profile in this configuration also have a sealing function at the same time, in the following the terms "sealing profile" or "sealing leg" synonymous with the terms "pinch protection profile" or "pinch protection leg" used.

A second sealing leg is expediently also provided, on the other Side of the groove wall rests under elastic prestress and so between the edge surfaces the resulting gap also covers the other side. In this way the anti-trap profile also acts as a pane and thermal insulation profile, as it two spaced apart on opposite sides of a receiving groove There are legs that enclose an additional air space in between and that also Always bridge the gap created when the plate parts are swiveled towards each other and seal.

In the preferred embodiment of the invention, the entire sealing profile is in one piece educated. It essentially defines a U-shape, with the two U-legs the mentioned, sealing leg accommodated in the groove and rests elastically on the groove ends are, which are connected to their lower sides via a crossbar, a Anchoring part is provided on this crossbar. The invention is expediently Profile made of polypropylene or another, permanently elastic but also sufficient made of rigid plastic. In the preferred embodiment, the outer U-leg is easily elastically bendably connected to the cross-connecting web, while the inner one U-leg is connected to the crossbar via a so-called "bending hinge". In in this case, the inner leg does not have to be elastically bendable overall, but first essentially like a hinge but still integrally connected to the connecting web. The connecting web is expediently designed such that it is the Shape of a conventional, trapezoidal projection is substantially adapted and this trapezoidal projection from conventional sectional gates, as shown in FIGS and 2 of the prior art is essentially covered. The anchoring part is in its outer form of the conventional one, which is incorporated in this trapezoidal projection Seal adapted, i.e. it consists of two essentially circular arcs Clamp legs, which also consist of a solid, elastically compressible, in Cross-section circular profile part could exist.

The receiving groove for receiving the elastically bendable profile leg is significantly deeper than a conventional groove and must of course be deep enough to be in any relative Position to be able to accommodate the sealing legs. Typically, this groove has, independent from the trapezoidal depression which is already known in the prior art an additional depth of 30 to 50 mm.

The greater groove depth within which the sealing legs are movably received in turn means that there are no fastening screws for hinge leaves in this area can be screwed in to a depth that falls in the area of the groove. As a result shorter mounting screws must be used for the hinge leaves, it is useful if at least on the plate part side, which has the groove, a larger one Hinge leaf with more mounting holes is used to adequately support the hinge can be securely attached to the plate part. Of course, for simplicity Both hinge leaves must be of the same design, so that one does not have to do so during assembly must pay attention to how the hinge leaves are aligned relative to the plate edges.

Further advantages, features and possible uses of the present invention will become clear from the description of a preferred embodiment and the associated figures. Show it:

FIG. 5 shows a position of the plate parts similar to that in FIG. 3, but with an inserted sealing profile,

Figures 6 to 9 different variants in which one or two plate parts are formed by a frame part for a window segment, and

Figure 10 shows a further variant of the present invention with a different anchoring part.

In Figure 1 you can see the hinge connection on a conventional sectional door without Pinch protection with a lower plate part 10, an upper plate part 20 'and a hinge 30, which lies outside the plate parts and on the inside of the plate parts. The lower plate part 10 has an approximately trapezoidal projection with a cross section Partially circular cavity for receiving a circular sealing profile 2 '. Outside However, the trapezoidal projection can be seen as flat, perpendicular to the plate and parallel to the hinge axis 35 aligned mounting surfaces 14, on which in the closed Position, as shown in Figure 1, sit two legs 24 of the upper plate part 20 '. A sealing profile 5 'fills approximately the upper half of the trapezoidal cavity 26 and occurs in the closed state with the trapezoidal projection 14 and the seal 16 engaged. The trapezoidal sides 27 of the cavity 26 run somewhat steeper than the trapezoidal sides the projection 28.

As can be seen in Figure 2, when the sectional door is opened, when swiveling of the upper plate part 20 with respect to the lower plate part 10 about the hinge axis 35 a relatively large gap to the inside, with the risk that a person's fingers, which engages in this gap during the closing movement of the gate, through the closing ones Edges of the two plate parts 10, 20 are crushed and injured.

According to FIG. 3, only the plate part 20 is slightly modified compared to the prior art been that the trapezoidal recess 20 by an additional, in the area the central plane of the plate provided groove 22 has been expanded. The groove 22 has a width of typically 4 to 12 mm and a depth between 30 and 60 mm (in addition to the depth the already existing trapezoidal recess 26).

The fastening screws 31 of the hinge 30, which are also according to the prior art through the inwardly folded outer and inner sheet metal cladding of the plate parts 10 or 20 can extend through, must be kept sufficiently short in this case, so that they do not extend into the groove 22. For this reason, if necessary at least on the side of the plate part 20 an enlarged hinge plate with additional Fastening openings are provided for attaching additional screws to provide sufficient secure connection between the plate part 20 and the associated hinge plate to ensure.

Figure 4 shows the same plate parts 10, 20 as Figure 3, but in the closed state and with an inserted sealing profile 1 according to the present invention. It falls in comparison to Figure 1 that the two plate parts 10, 20 even in the closed state clear distance from each other, which is filled by the anti-trap profile 1.

An anchoring profile 2 in shape can be seen on the anti-jamming profile 1 according to the invention two arches semicircular in cross section. These are in one piece essentially molded horizontal connecting web 5, which an outer profile leg 3 and one inner profile leg 4 connects. However, the connecting web 5 is open the inside is bent downwards and essentially follows the course of the trapezoid wall of the trapezoidal projection of the lower plate 10. At the lower left end of the connecting web 5 there is an elastic bending hinge 9 made of permanently elastic EPDM, which is biased so that it the inner profile leg 4 of the connecting web 5th pushes away, i.e. against the lower edge of the groove 22 or against the inner wall of this groove 22.

The outer profile leg 3 is also integrally formed on the connecting web 5 and lies on the outer wall of the groove 22. In addition, the outer profile leg 3 is still around extends a sealing leg 7, which extends on the outside of the trapezoidal projection of the lower plate part 10 and which also has an outer sealing lip 8, which in the closed state with the inner surface of the trapezoidal recess of the engages upper plate member and the gap between the lower plate member 10 and the top plate part 20 tightly seals to the outside.

When pivoting the upper plate part 20 relative to the lower plate part, as in Figure 5 is shown, it can be seen that the outer profile leg 3 is bent elastically and always bears against the outer wall of the groove 22. The profile leg 3 forms an arcuate transition between the trapezoidal projection of the lower plate part and the groove 22 of the upper plate part 20, through which the between the plate parts in particular largely covered on the outside gap and is protected from interference with the fingers of one hand. The inner leg 4 follows in the open position due to the elastic preload of the hinge Pivotal movement of the upper plate part 20 and thereby closes the between the upper and lower plate parts 10, 20 on the inside forming gap in particular between the individual hinge elements, so that even from the inside, an intervention with the fingers of one hand is avoided and thus a secure protection against jamming is guaranteed.

The exact shape of the inner and outer profile legs 3, 4 does not exactly matter since they are made of an elastically bendable material, which is each adapts to the acting forces.

It is only essential that through the inner and outer profile legs 3, 4 when pivoting of the plate parts 10, 20 positively forming gap before engagement by the fingers a person is largely protected, or vice versa, the fingers of a person be protected against jamming between the upper and lower plate parts that the engagement between these plate parts in any relative position of these plate parts by the Profile parts 3, 4 is prevented.

Figures 6 to 9 show different variants of plate parts, with the top and sometimes the lower and sometimes both panel parts through profile frames 40 and 50 for window elements are replaced. The basic shape of the edge surfaces remains essentially the same and also the basic structure of the profile part with an inner and outer, each elastic against a grooved leg is retained so that it does not appear necessary discuss further details of these variants. Only the groove 42 points because of the limited space available to a shallower depth than the groove 22 but this is characterized by a gently curved groove base and a lateral extension.

Figure 10 finally shows a variant with a modified anchoring part. In In this case, the anchoring part 2 "consists of a narrow, deeper into a gap in the lower The part of the plate is embedded, which is not elastically tensioned, but by a continuous one Fixing screw for the lower hinge leaf in the lower plate part 10 " is secured.
