DE3133336A1 - Detachable jointed connection of a plurality of plate-like wall parts - Google Patents

Abstract

The invention relates to a detachable jointed connection of a plurality of plate-like wall parts, the connection between the plates, as is shown for example in Fig. 4, consisting of a material which is elastic in shape and expansion. Such materials may be of a textile nature but may also consist of plastics or of elastic metals. The jointed connections allow exhibition stands, temporary dwellings and furniture to be produced. In cases of severe stress, the clamping effect can be reinforced by penetrating screw connections. Stresses to the interior or exterior are absorbed by cords or spacer rods. <IMAGE>

Description

Riedel: "Detachable articulated connection ..." 08/20/81

The invention relates to a releasable articulated connection of several plate-like wall parts by means of these overhanging and comprehensive double clamps. Such connections will prevail used in the field of exhibition and display, because there it is important to produce spatial structures from panels, which have to be released again after a predetermined time for the purpose of dismantling.

Articulated connections are known per se from hinge technology, but these hinges have the overall disadvantage that their attachment to the panels, regardless of whether on the cross-sectional side or on one of the cover sides, must be done at relatively short intervals by screws, so require a lot of time.

Another disadvantage are the modern compressed wood panels that Only hold screw connections unreliably and tend to loosen with repeated use.

The invention has set itself the task of producing a very quickly hot adjustable connection of two panels to create that just as quickly

to solve is how to assemble. In addition to a reliable adhesive connection, it should also be aesthetically pleasing and enable a screw connection for very heavy loads.

To this end, the invention is based on a releasable articulated connection by means of the plates protruding at the edge on both sides and comprehensive double bracket, and it is characterized in that the bracket-like enclosure, preferably in the form longitudinally slid pieces of pipe, the plates on the slot side of the Pipe pieces with the slot surfaces flat, linearly on the inner side remote from the slot, and dimensionally as well as stretchable Means connect the pipe pieces together.

According to a particular feature of the invention, the form and stretch elastic means can have a band-like character. The bands can be fastened on one outside or on both outside of the pipe sections facing each other with the slit-free side.

Another feature of the invention can be the elastic Means to be attached as an elastic band on the side of the pipe sections remote from the slot and facing away from one another.

The figures represent exemplary embodiments of the invention. They show:

Figures 1 to 3 show an embodiment of the invention with the ribbon-like connecting means 30, FIG. 1 showing a one-sided ^ Connection and Figures 2 and 3 represent a double-sided connection of the pipe sections 11a, 11b.

The plates 20 are clasped flatly at the edge by the slot surfaces 12, and they are supported in the interior of the pipe sections linearly at the points 13, so that the plates 20 on their Rardern 21 are flat and held with their edges linearly.

FIG. 4 shows an articulated connection 40 between the tubes. pieces 10. The clamping connection is the same as in the Figures 1 to 3, and between the pipe pieces there is an elastic double-sided adhesive tape. The elastic double-sided adhesive tape can through one of the usual keel connections with elastic Character to be replaced.

FIG. 5 shows a pipe section with conically widened slot ends 14. These slot ends facilitate the insertion of the plates 20 during assembly. Touch for all graphic representations the slot surfaces 12 for reasons of drawing the plat-

ten not 20.

In practice, however, the slots 15 are in relation to the plate thicknesses dimensioned so that a considerable clamping effect occurs.

Figures 6 and 7 show an exhibition wall with two panels 20, which are clamped together by an articulated connection. The advantage of such connections is, among other things, that Bends between two plates (20) of up to 90 are possible ο

The figures also show that for attaching shelves or other Wall elements support holder 90 are thereby attached at a suitable height can that according to the detailed drawings of Figures 8 and 9, the pipe sections 11 are perforated and on the each opposite side of the perforation have a toggle nut 51 which is screwed onto the screw 50. Using this screw system not only can the screwing effect be increased considerably. The toggle nut also carries the tubular Carrying holder 90, which is secured against displacement by the head of the toggle nut.

In the figure 10 is shown how in a spatial structure through Tension cords 60 static fixed points can be formed. By means of the upper and lower end plugs, which are inserted into the articulated connecting pieces 11a, 11b, and the cord

You are so Arranged low on the ground so that they disappear in a carpet laid over it and are neither obstructive nor obstructive on the upper side of the plates 20 still practically visible.

It is also within the scope of the invention, instead of the tension cords Use spacer rods that are anchored in the connection plug.

In the figure 11 is an articulated connection of the inventive type shown, which consists of a connecting middle piece 16, in that the pipe pieces are pushed in on friction. In the frame part of this figure a catch-like grid is visible, which is höhunyen and depressions allow movements around the central point of the connecting middle piece 16, but these movements in the cavity 17 by snapping the pipe sections 11 into the grid difficult.

In the figure 12 a clamp-like enclosure is shown, which can be produced from materials of different elasticity, wherein the stirring pieces made of a comparatively harder material compared to di r more elastic middle bridge 41 exist. Such different material characteristics can be represented by modern extrusion technology.

In Figures 14 to 16, an exhibition stand is shown in which the plates 20 at least at the head end over the end plugs 70 with tension cords 60, optionally spacer rods, to one another. are bound.

FIGS. 15 and 16 also show how a connection is made can be designed structurally between the vertically placed plate 20 and a roof plate.

The force diagram of Figure 16 shows that the load pressure to the outside by the tension cord 60 or a corresponding spacer rod, which can also absorb pressure inwards, is intercepted »

Three or four plates 20 can also be used on the principle of egg- connection with each other if the elastic middle piece is used as the core of the pipe connection.

particularly at international trade fairs have to be transported long distances and have to be transported back at the end of the trade fair. That isL at foreign trade fairs uneconomically expensive.

In the context of the invention, relatively cheap sheets of corrugated cardboard can be used or panels made from inexpensive wood fibers can be used, and the articulated connections can be made from regenerated plastic so that the material can be left in place as waste material or at any time. That is much more economical than a return transport, for example from abroad.

The principle of the invention also allows jamming of components for the production of so-called portable furniture, which can be easily put together by any hobbyist, to and after the figures 14 to 16 it is also possible to build temporary apartments, for example for emergency operations in the event of a disaster.

Another major advantage is the stiffening function of the Double bracket. It is thus possible to use very much thinner and thus economically favorable plate-like wall parts 20.
