AT2801U1 - SELF-LOCKING FOLDING WALL - Google Patents

Abstract

The invention relates to a folding wall which is composed of regular strips (Z1, Z2, Z1) which are arranged next to one another and run in the folding direction of the wall and which in turn consist of segments (S1, S2, S1) which are connected to one another in an articulated manner. Z2, Z1), or their segments (S1, S2, S1), engage over their entire length at their contact edges (3,4,3,4) with grooves (5,5) and tongues (6,6) or in similarly to one another, each segment (S2) of a strip (Z2) being assigned a segment (S1, S1) of the adjacent strips (Z1, Z1) and the mutually assigned segments (S1, S2, S1) abutting each other with the same edge length . With correspondingly arranged articulated connections (1, 2, 1), all strips (Z1, Z2, Z1) can be folded up or unfolded simultaneously and equally. The grooves (5, 5) form continuous guides when the wall is unfolded, so that the strips (Z1, Z2, Z1) can be moved relative to one another, and a locking effect is achieved in that, with a corresponding displacement, all the springs (6,6) are inserted in two grooves (5,5) at the same time and thus the articulated connections (1, 2.2) can be blocked.

Description

AT 002 801 Ul

The invention relates to a self-locking folding wall or a similar self-locking foldable element, whose or its articulated components can be locked together due to the construction of the wall or the like, without the need for additional devices, bars etc.

As already shown in the published patent application DE 197 19 1 ^ A1, the task is based here, too, on the movable individual parts of a completely unfolded wall or the like. by means of a structurally simple and easy-to-use mechanism in such a way that the wall or the like. becomes a rigid disk or plate.

DE 197 19 1 ^ AI describes a locking system for folding walls or similar foldable elements, the effect of which is essentially based on the fact that by moving from within the folding wall or the like. the articulated connections of the slats are blocked transversely to the slats and locking chains arranged in continuous guides. The bar chains consist of rod-shaped individual elements, with each guide segment determined by the slat width being assigned a bar element corresponding in length to it and thus folding the wall or the like. is possible.

In contrast, in the present case, to achieve the object, the invention provides that the folding wall, or a similar foldable element, consist of regularly arranged side by side and the like in the folding direction of the wall or the like. extending strips is composed, which in turn consist of articulated segments. The strips, or their segments, engage - over their entire length - at their contact edges with tongue and groove, or in a similar manner, the segments being dimensioned and arranged in their length in such a way that one segment of a strip each a segment is assigned to the adjacent two strips and the mutually assigned segments butt each with the same edge length. This makes it possible to fold or unfold all the strips simultaneously and equally in the same way alternately arranged in the same way. "Furthermore, it is provided that the individual grooves arranged on the edges of the segments each have a completely unfolded wall or the like." form a continuous groove or guide so that the strips can be moved parallel to each other. A locking effect is achieved by simultaneously inserting a spring of one segment into two grooves of the segments of an adjacent strip and thus the joint 2 AT 002 801 Ul

Connections of the segments are blocked.

In terms of stability, it is advantageous if a folding wall or a similar foldable element consists of two, narrow, edge strips and one, wide, whereby for the edge strip segments, well-known U or C profiles made of metal or plastic are used can be whose hollow shapes are suitable as a guide for the flat, median strip segments inserted with appropriately designed edges.

The median strip can, depending on the purpose of the foldable element, be made of segments with a closed surface or grids or conductor-like segments - e.g. in the case of a foldable shelf side wall composed of vertically arranged strips.

It is also an advantage if - with folding walls or similar. with vertically arranged strips - the springs or the edges of the segments have dovetail or club-shaped cross sections and are inserted into appropriately adapted grooves or profiles. In this way, the strips, which can be moved parallel to each other, are connected to one another and the possibility of designing self-locking foldable elements, the width of which is changed by the locking process, in that hi e are composed of wedge-shaped or tapering strips that are alternately arranged side by side. When the strips are moved against each other, they are pushed apart or contracted. 3 AT 002 801 Ul

With the help of the accompanying drawings, the mechanism of a self-locking folding wall or similar self-locking folding element is explained as follows. Show it :

1 and 2 are isometric representations of a foldable element similar to a folding wall in the stage of folding or unfolding (FIG. 1) and fully unfolded and locked (FIG. 2);

Fig. 5 and Fig. Jf partial cross sections through two with groove and tongue interlocking strip segments;

5 and 6 show partial cross sections through segments of folding walls, the edge strips of which consist of U (FIG. 5) and C profiles (FIG. 6);

7 isometric representation of a foldable shelf side wall, the central strip of which consists of ladder-like segments connected with double joints.

The folding-wall-like element is composed of three strips (Z1, Z1 ', Z2, Z3, Z3', Zb) running in the direction of folding, the strips (Z1, Z11, Z2, Z3, Z3 ', Z4) each consisting of segments (31, 51 ^ 32,33,3 ^, 35,36,59 ^ 2), which are connected by joints (1, ^, 1 ^, - 2,22).

Each segment (S2, S * f, S5, S9) of the central strip (Z2, Z4) is assigned a segment (S1, S1 ', S3, S6, P2) of the two edge strips (Z1, Z11, Z3, Z3') . The segments assigned to one another (S1, S1’tS> 2tS3.5k, S5, S6, S9, P2) engage at their contact edges of the same length (3, ^, 31 »12)

Grooves (5.5 ', 9.13) and tongues (6.6', 10.14) or in a similar manner. (Fig.1, Fig.3, Fig.4)

The edge strips (Z3, Z3 ') can also consist of segments (P1, P2) in the form of U or C profiles, into which the strip segments (S7, S8) arranged between them are inserted with correspondingly designed eaves (15, 16) are. (Fig.5, Fig.6, Fig.7)

When the element is fully unfolded, the grooves (5 »5 '* 9, 13) or the profiles (P1, P2) form continuous guides, so that central (Z2, Zif) and edge strips (Z1, Z11, Z3, Z3 * ) can be moved against each other and a locking effect is achieved by inserting a central strip segment (S2, S9) into two edge strip segments (S1, S1 ', P2) and blocking the articulated connections (1,1 *, 1 ", 2-, 22) causes.
