Description

1

A problem which is frequently to be solved in especially smaller houses, such as single-family homes, is the lack of space that constantly occurs there, whereby the use of the roof space of the houses, e.g. is a possibility used in most cases for storing items that are currently or not used for a long time, storing building materials and the like. Although such an attic or loft should be accessible in itself, but a built-in, leading there staircase in most cases is not necessary and not desirable because they also just space that could be available for other purposes, claimed, and wherein such a staircase, since it is relatively rarely used, no special aesthetic or other claims are made security in their visit.

There are therefore for a long time the most diverse proposals for openings in the ceiling have been made towards a roof space, the closure lid are designed so that they are as little as recognizable as covers of openings in the ceiling, but on the other hand, if necessary - usually obliquely-fold down, which can be ascended by means of a on the one hand on the folded closure lid and the other below the ceiling opening on the ground supporting climbing aid in case of need in the attic. In the simplest case, such a climbing aid could be a longer conductor which can be leaned against one of the edges of the ceiling opening, but this is not popular because it itself requires space again.

Rather, it is in the largest number of such ceiling opening closure organs, so closure lid, it is common that they roof top side, the top side, a multi-part, for example, collapsible or collapsible ladder or such, equipped on both sides with longitudinal bars stairs or a one-piece scissor-stairs have which after opening the ceiling hatch at then obliquely folded down closure cover to the full length extendable or auseinandereinklappbar and are finally supported in an inclined position on the floor located below the ceiling opening.

Most of the time, such ceiling-opening lids are today required to have them, e.g. in the event of a fire in the loft, smokers and broad propagation are supposed to act, so that at least the closest possible match of closure lid and ceiling opening edge takes place.

A large number of proposals for such closures have already been made and realized. For this purpose, for example, only EP 2474684 A2 mentioned, which has a ceiling opening closure lid with a special hinge mechanism and a collapsible with him multi-part folding staircase with matched to the lid spring-loaded multi-lever mechanism to the object. 2/14 2

A very essential part of a ceiling opening closure lid equipped with the above-mentioned climbing aid is its special hinge connected to the walls of the ceiling opening, which must ensure that, on the one hand, in the closed state of the lid, a secure, all-round contact is guaranteed on all edges of the ceiling opening in that on the other hand the Abkappvorgang can be done easily after loosening the lid-closing mechanism and that ultimately after the unfolding of the ladder a stable and safe rise in the overhead floor, so in particular attic, can take place.

The object of the present invention is now, in particular, that - preferably with regard to the train and fire propagation prevention - the hinge mechanism when folding the ceiling opening cover to ensure that when opening the same in a first phase a The same parallel displacement of the same from the closed position downwards takes place before then in a second phase of the lid enters the inclination and the climbing aid can be finally pulled apart or unfolded to the underlying ground for the support of the ladder and their two-sided longitudinal beams.

The present invention is thus a new ceiling opening closure member with an obliquely downwardly pivoting closure lid with two side walls of the ceiling opening, in particular Futterkastenwänden, arranged on opposite side walls, and on the closure lid hinged at the top hinged multi-hinges, wherein it is preferably provided that the closure lid on the top associated with him a plurality of interconnected, to a ladder apart-folding or -ziehbare ladder parts or a Scherentreppenpaket carries, which is characterized - that - for a attainable before reaching the oblique position of the closure lid at its opening, parallel to move downwards of the same - each of the two multi-joint hinges two scissor-like intersecting, one another about an axis in a crossing point pivotable longer main arms, - of which a first main arm at one of his E nden is hinged to a fixedly arranged on the Futterkastenwand first pivot point, and - a second main arm is articulated at one of its ends to a fixedly arranged at the top of the closure lid pivot, - that the first main arm at its other end to the end of a first side arm hinged, which with its other end at one - in fixed 3/14 3

Distance from the top lid pivot point, also arranged at the top of the closure lid pivot point is hinged, and - that the second main arm is hinged at its other end to one end of a second side arm, which in turn with its other end at its remote from the first pivot point arranged second, fixedly mounted on each of two mutually opposite lining walls pivot point is hinged to the respective Futterkastenwand.

With the help of just described inventively used new hinge mechanism can be said, the above-mentioned goal of the two-phase opening of the closure lid, namely its first parallel displacement and the same following Schrägabklappung same precise achieve and next ensures - in addition to the tightness against train and fire propagation - the new mechanism a high degree of stability in most cases with the closure lid in connection with fold-down ascent assistance in particular.

In this sense, it is preferred in the context of the invention, the new closure member in such a way that the multi-joint hinge has two hinge portions which, in each position of at least obliquely to a ceiling downwardly pivotable closure cover in shape from said respective position of the multi-joint hinge and thus Also defined as mutually dependent, each having the form of non-uniform, approximately trapezoidal quadrilaterals each having constant lengths of their bases and have, while the respective three other associated sides of the two squares and each defined depending on each other are pivotable to each other.

Furthermore, it has proved to be favorable in the new closure member, when - with closed, parallel to the ceiling plane, in particular Deckenflächenschlüssig, and usually horizontally arranged closure lid, the two pivot points are connected to each other at the top by a likewise horizontally arranged to the closure lid top parallel connecting line while the connecting line between the two pivot points on the opposed box walls is at an acute angle to the plane of the ceiling.

In summary, the advantages of the multi-joint hinge to be used according to the invention are essentially the following:

The new hinge directs the lid, e.g. By up to about one third of the total movement, parallel down and then backwards: For this reason 4/14 4, the lid can certainly be performed with high strength, as it is due to stronger insulating layer.

The passage light of the ceiling opening does not become smaller, and thereby the unfolding is e.g. a folded three-piece and consequently relatively large height, e.g. staircase package designed as a scissor stair package not affected.

Of course, the lid of the stairs can be opened and closed without a staircase package.

Last but not least, in the case of a closure cover for ceiling openings designed in accordance with the invention, it is required that the mechanism for a multi-part ladder or staircase sloping down together with the closure cover be compatible with the new cover hinge mechanism and, accordingly, in the ceiling opening described above. Closure organ further advantageously provided, - that after opening and folding of the closure lid hinged, multi-part ladder or stairs - which is fixed in the region of the upper ends of their two spars each with a side bar each of a triangular lever and mutually immutable, - the free triangular lever Corner areas of the same are hinged to a, preferably hollow, shaft, hinged to two opposing box walls, by means of bilateral, permanently tensioned multi-lever mechanisms in each layer of the versc Each of the two multi-lever joint mechanisms is articulated by means of a pull lever, flexibly connected to a pull lever, which at one end to a, arranged on a holding bar connected to the support box, articulated first joint Articulated lever is hinged, which is hingedly connected at its other end to one of the ends of a second articulated lever, which in turn articulated in each position of the closure lid via a the ladder or stairs supporting, preferably hollow, shaft formed joint on a itself on the closure lid Distance lever od. Like. Is articulated.

Reference to the drawing, the invention is explained in more detail:

1 and 2 show in detail a section through the hinge-side part of the ceiling opening closure member according to the invention with anchored in the lining box of the opening novel hinge mechanism at first closed and then opened, obliquely folded down ceiling cover cap and Fig. 3 a equipped with the inventively used new hinge mechanism 5/14 5 equipped closure lid together with a multi-part folding staircase and their independent from the cap lid hinge mechanism, but matched to the same, an abrupt folding down the stairs preventing stair-motion lever mechanism, for the high stability and climbing safety the ultimately folded and unfolded stairs concern.

It can be seen from Fig. 1 in conjunction with Fig. 2, as in the closure member 100 in the ceiling opening 90 in a ceiling 9 within a fitted into this opening 90 box with the Futterkastenwänden 51 (left) and 54 (rear) and 52 (not shown, front) the new hinge mechanism 10 is installed and how it is connected to the hinged closure lid 8 with the Isolierauflage 80 on its upper side 81.

It is further shown there that each of the two multi-articulated hinges 10 arranged on both sides has two longer main arms H1 and H2 pivoting relative to one another about an axis at the point of intersection K, of which the first main arm H1 is stationary at one of its ends E1 each arranged on the Futterkastenwand 52, 54 arranged first pivot point D1, and the second main arm H2 is articulated at one of its ends E2 to a fixed to the upper side 81 of the closure cover 8 pivot point D2.

Furthermore, the first main arm H1 is connected at its other end E11 to the end En1 of the first sub-arm N1 articulated G1, in turn with its other end En 11 on the - at a fixed distance b from the top lid pivot point D2, also on the top 81 of the closure lid 8 is pivoted at its other end E21 to the end En2 of a second sub-arm N2 hinged G2, which in turn at its other end En21 at its distance a from the first pivot point D1 arranged second, fixed to each of the lining walls 52, 54 arranged pivot point D4 is hinged to the respective chute wall 52, 54.

By this new type of multi-joint hinge mechanism 10 is ensured that at the beginning of the oblique flap of the closure lid 8, so before the Schrägabklappvorgang begins, first a short period of parallel displacement of the lid 8 to the original, parallel to the ceiling bottom 91 or with its coextensive position of the Cover 8 is done. This is in particular for securing an actually all-round firm concern of the cover 8 or of its all around, such as. Here, protruding edges 82 on the likewise all around edge limbs 92 of the ceiling opening 90 important, so that, apart from a possibly built-in insulating strip, virtually no gap between the closure lid 8 and wall of the 6/14. 6

Ceiling opening 9 remains free, through which any unwanted draft could occur or in case of fire would be a breakthrough fire enabled.

FIG. 2 shows otherwise identical reference numerals in the same detail sectional view as FIG. 1 the closure lid 8 folded out of the ceiling opening 9, where it can be seen that the multi-joint hinge 10 has two hinge areas 101, 102, which in each position of the obliquely to a ceiling 91 downwardly pivotable closure cover 8 in shape from this respective position of the multi-joint hinge 10 and thus also defined from each other dependent each have the shape of uneven trapezoidal quadrilaterals each having constant lengths of their bases a and b, while the three other associated pages h1, h22, n2 and h2, h11, n1 of the squares are defined in each case in a mutually defined manner, pivotable relative to each other.

In particular, from Fig. 1, but also from Fig. 2 has also been seen, as with closed, parallel to the ceiling plane 91 and thus horizontally arranged closure cover 8, the two pivot points D2, D3 at its top 81 by a horizontally disposed, for Cover cover top 81 parallel connecting line b are connected to each other, while the connecting line a between the two pivot points D1, D4 respectively at the opposed Futterkastenwänden 52, 54 at an acute angle α to the plane 91 of the ceiling 91 runs.

From Fig. 3 is - with otherwise constant reference numerals -sichtlich how the cap 8 on the top side with a plurality of hinged together ladder or stair parts 171 formed, thus auseinaderklapp- or -straight ladder or stairs 107 with total poles 170 carries, in which provided is, that the hinged after opening and tilting-down of the closure lid 8, multi-part conductor 107 in the region of the upper ends of their two Flolme 170 and Holmteile 171 each with a side bar 133 of each triangle lever 130 is fixed and thus mutually unverschwenkbar connected, - each of the free triangular lever corner region 134 is connected to a hollow shaft 103 hinged to the two opposing box walls 52, 54 by means of bilateral, substantially permanently tensioned multi-lever mechanisms 105 in each position of the closure cover 8 and thus the ascent aid 107 lagefes t are positionable and - wherein each of the two multi-lever joint mechanisms 105 is articulated by means of the tension spring 101 flexibly connected to pull lever 111. It is articulated via a joint 113 to a - with one end to a, on a with the fodder box 5 7/14 7 connected holding bar 121 od. Like. Arranged, articulated joint 122 hinged first articulated lever 112 which in turn with its other end with a the ends of a second articulated lever 113 is hingedly connected, which in turn in each position of the closure cover 8 via one with the ladder 107 supporting here hollow, here with an upstanding support bar 145 equipped shaft 140 formed joint 141 on the itself on the closure lid. 8 articulated about a hinge 142 articulated distance lever 114 is hinged.

In addition, it should also be noted that the lining wall 51 opposite right-side lining wall is denoted by 53 and the closure cap-closing mechanism with 85. 8/14
