Description
-` 2~7~93!5 ARCHED STRUCTURE
Technical Field This invention relates to an erectible and collapsible arched structure suitable for easy and rapid assembly and erection for temporary use, for example, in supporting a roof or cover. In particular, there is a military application for such a structure for rapid deployment in supporting a cover or camouflage net over military equipment such as tanks or aircraft.
Arched structures have been proposed comprising a plurality of segments which are connected end-to-end so as to extend longitudinally as an arched form in an upright plane when erected.
Hinge connections are provided between adjacent ; segments with axes extending laterally of said upright plane, and abutment means are provided at the ends of adjacent segments so as to cooperate in compression when the arched structure is erected. A cable extends longitudinally of the arched structure and cooperates with each segment so that when tensioned, it holds the structure in its erected arched form. However, these proposed arched structures are not easy to erect, and are not designed to be readily collapsible so that 2Q7~?~;
they can be removed and re-erected elsewhere.
Disclosure of the Invention An object of the present invention is to provide an arched structure which is readily erectible and collapsible.
This is achieved according to the invention by providing an arched structure comprising a plurality of segments which are connected end-to-end so as to extend longitudinally as an arched form in an upright plane when erected, a hinge connection being provided between adjacent segments with a hinge axis that extends laterally of said upright plane, abutment means being provided at the ends of adjacent segments spaced inwardly of the hinge axis towards the underside of the arched form so as to cooperate in compression when the arched structure is erected, and a cable extending longitudinally of the arched structure between end segments thereof along a path spaced inwardly of the hinge axes and cooperating with each segment so that when tensioned it holds the structure in its erected arched form, characterised in that winch means is provided on the arched structure which is operable 2~7~5 to tension and shorten the cable between said end segments so as to erect the structure into its arched form, and to extend the length of the cable between said end segments so as to allow the structure to assume its collapsed form.
The winch means and cable serves to lift the segments into their erected arched form, and can be maintained in a tensioned state once erected to lock the ends of the arch a fixed distance apart and prevent it from collapsing, or at least to serve as a safety feature to prevent collapse if additional means are provided to fix the ends of the arch in position.
The cable, as well as extending along the length of the arch, may extend across a chord of the arch between its ends so that both ends of the cable are secured to one and the same end of the arched structure. Tensioning of the cable with the winch means will then apply a further force directly between the ends of the structure to pull them together. However, that section of the cable between the ends of the structure may be adapted so that it can be uncoupled once the structure is erected leaving the rest of the cable still 2~7~39~5 fastened between its ends, The floor space within the erected arch is therefore left unimpeded.
In order that the cable is of maximum affect, it is located at a maximum distance inwards from the hinge axes, preferably being located inwards of the abutment means.
The arched structure will usually be substantially symmetrical about an upright central axis when erected. The central shape of the arched form will be determined by the lengths of the segments and the angles defined between adjacent segments by the abutment means. If the segments are all substantially the same length and the abutment means define a common angle between adjacent segments, then the arched form will lie on a circle. However, alternative variations are possible.
According to a further feature of the invention, restraining ties are provided between adjacent ends of the segments so as to limit the hinging action therebetween when the structure is collapsed, thereby holding the segments in a predetermined form above the ground, supported at .
, .
~ - .
2~79~5 hoth ends, when fully collapsed.
The restraining ties may each take the form of a slotted plate with a pin on each segment engaging a slot in the plate that accommodates the hinging action but has one end that the pin engages when the structure is collapsed. The pins on adjacent segments may engage opposite ends of a common slot in the plate when the structure is collapsed.
Preferably, the abutment means and restraining ties may be combined, for example, by arranging that the pins of adjacent segments in a common slot, as described above, also abut one another when the structure is in its fully erected form.
Ground engaging wheels may be provided at each end of the structure so as to make it mobile and facilitate erection of the structure.
Description of the Drawings The invention will now be described by way of example with reference to the accompanying drawings in which:
2~ ~ ~9~5 Figure 1 shows a side elevation of an arched structure according to the invention in its erected state, Figure 2 shows the hinge connection between adjacent segments of the erected arched structure in Figure 1, Figure 3 shows a side elevation of the arched structure of Figure 1 when collapsed, Figure 4 shows the hinge connection between adjacent segments of the collapsed arched structure in Figure 3, and Figure 5 shows a plan view of the arched structure as collapsed in Figure 3.
Mode of Carrying Out the Invention The illustrated arched support consists of eight similar segments 1 which are each hingedly connected end-to-end to an adjacent segment so as to extend longitudinally as an articulated structure. Each segment 1 consists of a rectangular framework of three upper longitudinally extending elongate members 2 spaced Z~7~5 apart laterally alongside one another, and three lower longitudinally extending elongate members 3 similarly arranged below the upper members 2, with all of these elongate members 2, 3 interconnected by ties and braces 4, as shown in the drawings, to form a rigid framework.
Adjacent segments 1 are hingedly connected together by pivot pins 5 which interconnect the respective ends of the upper elongate members 2 and define a common lateral hinge axis X-X, shown in Figure 5. The hinging movement of adjacent segments 1 relative to one another is limited by slotted plates 6 which each interconnect a respective pair of adjacent ends of the lower elongate members 3. A pin 7 extends laterally from the end of each lower member 3 ahd engages within a longitudinal slot 8 at one end of a respective plate 6 so that the pins 7 at the ends of adjacent pairs of lower members 3 are free to move longitudinally within their respective slots 8 as the segments hinge relative to one another.
At one extreme collapsed position, the pins 7 engage the outermost ends of the slots 8, as shown in Figure 4, and the plate 6 serves as a 2~7~35 restraining tie to hold the segments in this collapsed position. At the other extreme erected position, the pins 7 engage the innermost ends of the slots 8, as shown in Figure 3, and the plate 6 serves as an abutment member loaded in compression to hold the segments apart in this erected position. The geometry of the hinge axis X-X, the pins 7 and slotted plates 6 is such that adjacent segments hinge through a predetermined angle between the collapsed and erected positions which is consistent with the number of segments 1 and the overall shape of the arched support- which is required; As shown in the illustrated example .with,.eight~,similar segments which~assume a 'sub an iall ~ ntal~state~'in.~the~collapsed~
'positIo'n,'znd'the geometry of the plates 6 and . ~, . : , pins 7 all the same, each pair of segments 1 hinge through 22.5 degrees between their extreme relative positions. In alternative embodiments, the spacing of the innermost ends of the slots 8 in each plate 6 could be different from one plate to another so as to vary the shape of the erected arched structure.
The arched structure is supported on wheels 9 at its extreme ends which are connected to the - ~j 21~7~3935 .
framework of the outer segments 1 at each corner and in the centre. This arrangement is such that the structure is mobile both when collapsed and erected. If desired the wheels 9 can be caster wheels so that maximum manoeuvrability is provided.
In order to erect the arched structure from the collapsed state, a cable 10 is provided which extends longitudinally of the structure between its ends, and is spaced inwardly of the main framework of the segments 1. This cable 10 extends through apertures;ll"in the ends of extensions 12-'which~'project~downwardly~-from~the~
lower-sl,d~e.,-of~the,~q~ ~ ~ jacen i,to ~ e end~of,~
each. The cable'10 is'tensioned'to;erect the arched structure by a'winch'13 at one:énd which winds in one end of the cable. The cable extends from the winch 13 round a pulley 14, across the space beneath the structure, and round a pulley 15 at the other end of the structure before passing through all of the apertures 11 in the extension 12 back to the end with the winch, where it is connected to the framework. Winding of the winch therefore applies a force directly between the ends of the structure which helps draw them 2~7~35 together as the structure is erected. Tension in the cable also exerts a hinging moment on the segments 1 through the extensions 12.
A lock device 16 is provided at an intermediate point in the length of the cable 10 which is located adjacent to the opposite end of the structure from the winch when the structure is erected, as shown in Figure 1. This lock device 16 is fastenable to the framework of the end segment, for example, by a pin engaging aligned .~, holes in the lock device and a plate on the ~ . , framework. Furthermore, a releasable~-connector 17 is provided in the cable lO at a~point-~located- ~ v '~ -~
betweéntthe,'lock evice 16'~an ,;th ~ o~
that this can be released once the lock dëvice is ' fastened to the framework so that the' length of cable extending directly between the ends of the structure can be moved clear of this space to allow unrestricted access.
Although, only one cabl~ lo and winch 13 has been described above, it will be appreciated that more than one can be provided depending on the size and width of the structure. For example, three cables and winches are shown in the illustrated , 2~ 5 embodiment.
In an alternative embodiment of the invention, the slotted plate 6 may be replaced by a similar plate having just a single slot 8 instead of individual slots for each pin 7, as shown in the illustrated embodiment. The ends of the respective lower members 3 are the pins 7 would then abut to define the erected position of the segments.
It will be appreciated that an arched support according to the invention may be manufactured as a "knock down" kit which can be readily stored or transported-to a site where it-is reauired for - -~usé~S ~ ~ s of the`~segments then being~
i~ ~ assembled and hinged together locally ready for use. When no longer needed, the whol'e structure can be disassembled and packed away ready for future use.
