DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates generally to a hinge connection, and more particularly, but not exclusively, to hinged connections of the kind which are intended to pivotally connect a first structural part or panel with a second structural part panel, so as to enable the two structural parts to pivot relative to one another.
Although the inventive hinge connection can be used for general purposes, it has been developed primarily for use in display systems, and then particularly with extendible and collapsible display systems which consist of a plurality of mutually coacting and mutually hinged panels.
Such display systems require the hinge connection to afford mutual rotation of 180.degree. or more between the panels.
In the case of more sophisticated display systems, when the front surface of a first panel or structural part is intended to face towards the front surface of a second panel, it should be possible to rotate the two panels so that the rear surface of the first panel will face towards the rear surface of the second panel.
Thus, it shall be possible for the panels to take any desired position in relation to one another between the aforesaid angular limits.
Of those types of known hinge connections used, among other things, in the type of display system briefly described above, the invention can be considered to relate more specifically to a hinge connection of the kind which will satisfy the abovementioned requirements and which includes a hinge element having a first hinge member which is attached to said first panel or part, and a second hinge member which is attached to said second panel or part, and also at least one band which extends between said panels and said hinge members.
A complete hinge connection of this kind requires at least two such hinge elements positioned adjacent one another, normally three or more hinge elements.
Hinge connections of the aforesaid kind, and thus also hinge connections according to the present invention, obtain particular suitable application in sign systems or display systems, and then particularly in portable sign systems or display systems of the kind which includes a plurality of panels positioned in edge-to-edge relationship, where each panel preferably comprises a frame structure or a covering surface with the frame structure embraced by a plurality of edge strips, wherewith at least two mutually adjacent edge strips or edge-strip parts belonging to respective panels are hinged together by means of one or more such hinge connections comprising a plurality of hinge elements.
In the case of the portable sign systems or display systems of this kind it is usual to use panels that have a right-angled configuration and therewith normally to use four edge-strip parts with each panel.
BACKGROUND PRIOR ART
Hinge connections that can be used in the aforesaid technical fields are known to the art in several different forms, and consequently the following description will deal solely with those constructions which can be used with portable display systems.
Since this field includes a large number of hinge connections, reference is made here to European Patent Publication 0 109 466 as an example of the present state of the art.
European Patent Publication 0 109 466 relates to a hinge connection intended for the aforesaid technical field, in which sprocketwheel-like coaction takes place between mutually adjacent panels.
It is also known to use hinge connections that comprise bands, of which one is attached to one side part of a first edge strip and to a second side part opposite the side part of an adjacent edge strip, whereas an adjacent band is attached to the one side part of the second edge strip and to the second side part of the first edge strip, therewith to define an "S" or a "Z" -shape, according to the principles applicable to the present invention.
As an example of the present state of the art, reference is also made to the illustrated and described subject matter of International Publication WO88/08186 (PCT/SE88/00171).
