Abstract

In a variable frame structure of the kind made from a plurality of interconnected rod or tube form frame members (14, 15), a connection between two frame members comprises a toothed strap (17, 18) wrapped around the periphery of one of the frame members and a nut (8) connected to one end of the other frame member. The nut (8) engages the teeth on the or a plurality of straps in threadlike manner so that rotation of the nut (8) in one direction causes the strap(s) to be tightened on to the periphery of said one frame member and the two frame members to be drawn towards each other. The nuts (8) advantageously form bush fittings in the ends of tubular frame members. The nuts (8) are advantageously fixed against rotation to the frame members, whereby the tightening of the straps can be effected by the rotation of the frame members about their longitudinal axes. The frame members are preferably of circular cross-section so that the straps can slide around the frame members to permit the relative disposition of the frame members to be altered. Where interconnected frame members define a closed frame, a panel member (4) figs 6, 7 (not shown) fitted in the frame may have concave edge formations (12) by which it is located on at least some of the frame members. <IMAGE>

Description

Improvements relatinq to Variable Frame Structures This invention relates to variable frame structures of the kind made from a plurality of interconnected rod or tube form frame members.
According to the invention, in such a variable frame structure, a connection between two frame members comprises a toothed strap wrapped around the periphery of one of the frame members and a nut connected to one end of the other frame member, the nut engaging the teeth on the strap in threadlike manner so that rotation of the nut in one direction causes the strap to be tightened on to the periphery of said one frame member and the two frame members to be drawn towards each other.
In the case where the frame members are of tube form, the nut conveniently may form a bush fitting in the end of the frame member. When the nut is fixed against rotation in the end of the frame member, the tightening of the strap can b effected by the rotation of the frame member about its longitudinal axis. When nuts are fitted in both ends of the frame member, their threads may be of opposite hand to allow rotation of the frame member to tighten up simultaneously the straps wrapped around the peripheries of frame members at both ends. Alternatively the threads may be of the same hand and the frame member split along its length to allow one end to rotate oppositely to the other end.
In order to connect the ends of several frame members together at a common unction, a plurality of straps Nay each be partially wrapped around a respective part of the periphery of a common frame member, the two ends of each strap extending into the nuts connected to different tubes.
The invention ill. now be described by way of example with reference to the accompanying diagrammatic drawings, in which: Figure 1 is a perspective view of a display panel assembly utilising a variable frame structure in accordance with the invention, Figure 2 is an exploded side view of a frame member and two connecting devices of the frame structure, Figure 3 is a view of one end of the frame member of Figure 2 as seen at 900 to the view of Figure 2 Figure 4 is a side view corresponding to Figure 2 but with the connecting devices fitted in the ends of the frame member, -Figure 5 shows a split form of frame member, Figure 6 shows one form of panel memebr, Figure 7 shows a second form of panel member, Figure 8 is a front view of another form of variable frame structure in accordance with the invention, Figure 9 is a side view of the frame structure of Figure 8, Figure 10 shows the manner in which two frame members can be connected to a further frame member at a common junction, and Figure 11 shows the similar manner in which four frame members can be connected to a further frame member at a common junction.
Referring to Figure 1, a display panel assembly suitable for use for example at exhibitions is shown. The assembly comprises a variable frame structure 1 comprising vertical frame members 2 and horizontal frame members 3 defining a plurality of rectangular frames and display panels 4 mounted in the rectangular frames. The frame members 2 and 3 comprise tubes of circular cross-section.
Each horizontal frame member 3 is connected at each of its ends to a respective vertical frame member 2 by a connecting device 5 shown in detail in Figures 2 to 4.
The connecting device 5 comprises a strap 6 which extends around the periphery of the vertical frame member 2. The strap 6 is formed with teeth on its outer surface. The free ends of the strap 6 pass through a guide 7 and a nut 8 and into the horizontal frame member 3. The nut 8 is fitted as a bush in the end of the frame member 3 and is secured against rotation relatively to the frame member 3.
To space the strap ends. apart so that the teeth on both ends of the strap 6 threadedly engage the nut at diametrically opposite positions within the nut 8, a pin 10 extends through the guide 7 and the nut 8. At its outer I' end the pin 10 is integrally formed with a saddle,which fits against the periphery of the vertical frame member 2.
Hence by rotating the frame member about its longitudinal axis in the appropriate direction, the strap 6 will be tightened around the- vertical frame member to draw the frame members 2 and 3 towards each other. Since a vertical frame member 2 is connected to each end of the horizontal frame member 3, the thread on the nut 8 at one end of the frame member 3 will be of opposite hand to the thread on the nut 8 at the other end. Hence rotation of the frame member 3 in the appropriate direction will tighten up the straps 6 at the two ends simultaneously.
Alternatively the threads on the nuts 8 at the two ends could be of the same hand. In this case it would be necessary to split the horizontal frame member 3 along its length, for example in the manner shown in Figure 5 so that the two ends of the frame member can be rotated independently. In Figure 5 the two parts of the split tube are shown interconnected by a member 19. The member 19 can takeany suitable form providing that it prevents the two parts moving apart and permits relative rotation of the two parts.
Each of the panels 4 is fitted within a rectangular frame formed by the horizontal and vertical frame members 2 and 3. Each panel 4 has a concave edge formation 12 along at least two opposite edges as can be seen in Figure 6. Thus when the straps 6 are tightened up the concaveeedges 12 fit around the vertical frame members 2 to locate the panels 4 in position. The concave edge formations 12 can be formed on the panels 4 themselves as in Figure 6 or they can be formed on separate edge pieces 13 which clip into or are otherwise secured to the edges of the panels 4 as shown in Figure 7.
Since the straps 6 when tightened up can still slide around the vertical frame members 2, the angles at which the horizontal frame members 3 (and hence the panels 4) in one vertical column extend relatively to the horizontal frame members 3 (and hence-the panels 4) in an adjacent column can b readily adjusted by manipulating the vertical frame members 2.
Figures 8 and 9 illustrate a three dimensional frame.
utilising the s am ., the onnec t i ng devices 5 between the vertical and horizontal frame members 2 and 3.
Figure 10 illustrates how the connecting devices 5 can be modified so that two frame members 14 and 15 can connect with a frame member 16 at a common junction. In this case two straps 17 and 18 are used. Each strap extends around a respective part of the periphery of the frame member 2.
One end of the strap 17 extends through the nut 8 of the connecting device 5 fitted in frame member 14 and the other end of the strap 17 extends through the nut 8 of the connecting device fitted in the frame member 15. Likewise the ends of the strap 18 extend through the nuts 8 of the connecting devices 5 fitted in the frame members 14 and 15 respectively. Tightening up of the straps is achieved as before by rotation of one or both of the tubular frame members 14 and 15.
Figure 11 shows how four frame members 20 to 23 can be connected to a frame member 24 at a common junction. In this case four straps 25 to 28 are used, each strap extending around a respective part of the periphery of the frame member 24. In similar manner to the arrangement of Figure 10, the two ends of each of the straps extend through the nuts 8 of connecting devices 5 of adjacent ones of the frame members 20 to 23.
The frame structures as described above have several advantages: 1. Various diameters of frame member can be gripped by the straps and such frame member need not be tubular.
2. The ends of the straps are neatly contained in the tubular frame members.
3. Adjustment of 3600 in vertical and horizontal planes is possible.
4. The panels are lockable in any position and any panel size can be used.
5 Both ends of a frame member are locked or unlocked simultaneously by rotating the frame member in one direction or the other.
6. The frame structure can be made very lightweight and the frame members may be of metal or plastics.
7. The straps at opposite ends of a frame member may be tightened simultaneously on to frame members of different diameter.
8. The saddle may be of flexible plastics material so that it accommodates different diameter frame members.
