Definitions

  • This invention relates to a collapsible, self-supporting fabric shelter.
  • Collapsible self supporting fabric shelters are reasonably well known and typically comprise a fabric canopy, a collapsible canopy support structure and collapsible legs.
  • Shelters of this kind find relatively common usage as advertising media, with the fabric of the shelters typically being used as a substrate for the display of advertising or graphics material.
  • a common complaint levelled at these fabric shelters, when used forthis purpose however, is that the structures thereof fail to provide tension support to the canopy fabric sufficient to provide a surface that is acceptably smooth, the inadequate tension of the fabric resulting in folding and creasing of the fabric across its surface, thereby lessening the visibility and impact of the graphics material on the fabric surface.
  • a collapsible, self-supporting fabric shelter is provided that is
  • Each flexible rib is preferably held in an upwardly bowed form by a support hinged to a
  • sliders are preferably of a cross-sectional shape adapted to minimise twisting of the flexible n ribs about their longitudinal axes.
  • the flexible ribs may conveniently be housed at their outer extremities in pockets located
  • the hub is preferably adapted to accommodate the ends of the flexible ribs against the
  • each leg is provided with an end block and with a leg
  • the leg sliders are located towards the foot of the leg
  • leg sliders are adapted to move from the first position to a second position in which:
  • the canopy is extended under tension to a dome shape by the bow of the flexible ribs;
  • the legs are locked in an extended position
  • leg sliders are locked in an extended position in a direction towards the top of the legs;
  • the twice braced support bows each corresponding flexible rib in position
  • the twice braced support is braced, first by the brace extending from the leg of the structure and, second, by the T-shaped brace;
  • the scissor-type linkages are opened and span the opposing legs to form a lattice beam along the lower periphery of the canopy.
  • the leg sliders may conveniently be comprised of an outer shell leg section saddled over and held captive on an inner leg section, the gap between the leg sections being sufficient to enable sand and dirt to pass between them without impeding the relative movement of the leg sliders.
  • the legs are preferably of robust construction and the leg sliders are adapted to be locked in their extended position by cam locking devices.
  • Figure 1 is a perspective view of one embodiment of the shelter according to the invention, in its erected position and with its canopy fabric in place;
  • FIG 2 is a similar perspective view of the shelter of Figure 1 in which the canopy fabric is shown cut away to reveal the structure of the shelter;
  • Figure 3 is a similar perspective view of the shelter of Figures 1 and 2 illustrating only the shelter structure
  • Figure 4 includes alternative views of one of the supporting legs of the structure, Figure 4a being an exploded isometric view of the components thereof and Figures 4b and 4c being similar isometric views illustrating the operation of the interengaging extruded tubular leg sections of the leg;
  • Figure 5 includes alternative views of another leg of the shelter structure illustrating the attachment of the superstructure to the leg structure, Figures 5a and 5b being isometric views showing a lower leg extension slider in different positions and Figure 5c being an exploded view of the components thereof;

  • the shelter illustrated in the drawings includes a fabric canopy 20, which is substantially
  • the frame structure includes four legs 21 , one at each corner of the canopy 20.
  • the canopy 20 is provided with a vent arrangement constituted by a vent
  • the framework is readily extendible from a collapsed position (which is shown in Figure 11 ) to the extended position shown in Figures 1 , 2 and 3 for example.
  • the immediate support of the canopy 20 is provided by flexible shafts or spreader ribs 23 that extend from a central apex to the corners of the canopy, each rib 23 being made up of a pair of components or rib sections 23a, 23b hingedly connected to one another by means of a hinge 23c.
  • the ribs 23 are positioned immediately below and bear up against the canopy fabric to support and extend the fabric into a tensioned, domed configuration.
  • Fabric pockets (not shown) are formed are formed on the underside of the canopy adjacent the corners of the canopy 20 to house an end of each spreader rib 23.
  • the ends of the flexible ribs 23 are not attached mechanically to any part of the structure and are essentially free floating above the tops of the legs 21.
  • the spreader ribs 23 are hingedly connected into a centrally positioned four-way apical hub 24.
  • Each of the flexible ribs 23 is divided into sections 23a and 23b which are coupled together by a hinge 23c which is shown in its fully open position in Figures 2, 3 and 7 and which is designed to hinge only downwardly from the position shown in these drawings.
  • Each of the flexible rib sections 23a and 23b has an irregularly pentagonal cross-section, with the apex of the pentagon inverted in the structure in use.
  • the base of the pentagon is relatively wide to provide a flat support surface for the fabric of the canopy and the apical sides of the pentagon are longer than the basal sides thereof, to improve flexibility.
  • each of the four legs 21 consists of a pair of telescopically nested, essentially tubular extruded aluminium leg sections, the extrusion profiles of which are complemental to allow the inner tube (the inner leg section 25 which faces inwardly into the structure in use) to telescope slidably within the outer tube (the outer leg section 26 which faces outwardly in use).
  • the outer tube 26 straddles and covers the inner tube 25 (in the collapsed form of the structure - Figure 1 1 in particular), with the complemental profiles of the tubes 25, 26 holding the inner tube 25 captive on the outer tube 26.
  • the outer leg section 26 is provided with a cap 27 to minimize the ingress of dust and sand into the gaps between the two leg sections 25, 26.
  • the extrusion profiles of the leg sections 25, 26 are designed to provide sufficient space between the slidably interengaged slideways to facilitate automatic gravitational discharge of any sand and grit that might get into the slideways or to permit flushing with water if necessary.
  • each leg 21 is provided with a foot 28 fitted to the lower end of the outer leg section 26.
  • the leg sections 25, 26 are provided with a cam-locking device 29 consisting of a handle and a cam wheel 29a which clips firmly and durably into a female component 29b positioned on the inner wall of the outer leg section 26.
  • a cam-locking device 29 consisting of a handle and a cam wheel 29a which clips firmly and durably into a female component 29b positioned on the inner wall of the outer leg section 26.
  • the leg sections 25, 26 are able to telescope by sliding relatively to each other through from the collapsed position of the structure illustrated in Figure 11 to the erected form thereof illustrated in Figures 1 to 3 in particular.
  • a partially extended position of the structure is shown in Figure 5a and a partially collapsed position is shown in Figure 5b.
  • the sections can be locked to one another in a selected position by the cam-locking device 29.
  • the legs 21 can also be adjusted independently of one another for the easy adjustment of the lengths of the legs 21 to accommodate any terrain on which a user might want to erect the shelter.
  • Figure 5 illustrates the use of sliders 30, 31 of extruded aluminium profiled complementally to the outer cross section of the inner leg section 25.

  • the end block 32 also has two lattice struts 41c, 41 d hinged to it on pivot studs 38 and
  • an additional pair of lattice struts 41 is pivotably connected into each side of the shelter, essentially constituting an intermediate link per side.
  • the size of the shelter can be increased, within practical bounds, by increasing the number of intermediate links.
  • the lattice struts 41 making up the intermediate links are pivotably connected to the lattice ' struts 41a, 41 b, 41c, 41 d connected to each leg section 25 by means of double-ended pivot studs 42.
  • the spreader ribs 23 are double-braced. This is achieved by double- bracing the rib support post 34 by means of a first brace element 43 hingedly connected to the end block 32 and a second brace element 46 hingedly connected into a cross-bracing system.
  • the first brace element 43 is connected between end block 32 and the rib support post 34 by hinge connections at either end.

  • each second brace 46 forms part of a bracing system that is connected to the lattice webs extending about the periphery of the shelter superstructure and that acts diagonally across each corner of the structure (in plan - when erected), but which also provides additional bracing to the ribs 23, thereby acting to stiffen the structure further against moderate to strong winds.
  • the bracing system is essentially in an inverted T- shape when the shelter is erected, the cross member of the T being composed of two struts 44a, 44b that extend diagonally across each corner of the structure, being pivotally connected, at their ends, to the lattice struts 41 a, 41 b extending from the intermediate slider 30 on the leg 25 and to each other at a hinge point 45.
