Definitions

  • the present invention relates to a foldable frame assembly. It is known to provide a foldable enclosure such as a tent, having a foldable frame assembly secured to a flexible material enclosure and foldable for convenient storage.
  • a foldable frame assembly comprising first and second end frame sections, the end frame sections each comprising a plurality of end frame members interconnected at a hub member, the end frame members being foldable relative to the hub member between a collapsed position and an erect position in which they radiate from the hub member, wherein the hub member is pivotally connected to a first end of said end frame members and has at least one support surface for supporting said end frame members in the erect position against folding other than in a predetermined direction, wherein the first and second end frames are interconnected by interconnecting side frame members pivotally connected to the end frame sections via corner joints with a second end of respective end frame members.
  • the hub member may further comprise a locking means operable to releasably fix the end frame members in the erect position.
  • the locking means may take many forms.
  • the locking means may comprise an elongate member, such as a screw or pin or the like movable relative to said hub member, the elongate member being movable from an unlocked position in which the end frame members are free to rotate to a locked position in which a portion of the elongate member prevents rotation of the end frame members, locking them in the erect position.
  • the elongate member is moveable within a channel in the hub member.
  • the channel may be substantially central and may be a longitudinal channel.
  • the locking means may comprise a rotatable disc attached via a pivot, which may be a central pivot, to the hub member, the disc being provided with a plurality of peripheral cut-out portions whereby the disc is rotatable from an unlocked position, in which the end frame members are free to move between the collapsed position and the erect position within the peripheral cut-out portions, to a locked position in which movement of the end frame members towards their collapsed position is prevented by the disc.
  • the locking means may be provided with a biassing means, such as, for example, a helical coil spring, to bias the locking means towards a locked position in which the end frame members are held in the erect position.
  • a biassing means such as, for example, a helical coil spring
  • the frame assembly is of a unitary construction, i.e. all of the frame members are interconnected, whereby the frame may be erected or collapsed without the need to connect or disconnect frame members.
  • the hub member may be provided with a number of support surfaces corresponding to the number of end frame members, whereby each end frame member is supported in the erect position by a respective support surface.
  • the (or each) support surface may comprise a stop or abutment.
  • the (or each) support surface comprises an open channel, the end frame members being supported in the erect position within the open channel.
  • the hub member may be formed from any appropriate material, including, for example, plastics or steel.
  • the support surface or surfaces support the erect end frame members in a position such that the hub member and each of the end frame members are substantially coplanar.
  • the end frame members are disposed substantially parallel to one another in the collapsed position and may be folded through approximately 90° into the erect position.
  • the support surface(s) may be positioned to support the erect end frame members at a range of angles relative to the plane of the hub member. For example, by providing support surface(s) that support the erect end frame members at an angle greater than 90° from their collapsed position, it is possible to produce a frame assembly having an outwardly sloping end frame. It is possible in this embodiment that the tension between frame and cover may be sufficient to lock the frame in erected position without the need for a locking mechanism.
  • the end frame members may be connected to the hub member by any suitable connecting means.
  • the end frame members are each connected to the hub member via a respective pivot pin or the like, whereby folding of the end frame members relative to the hub member is achieved by pivoting of said end frame members about said pivot pin or the like.
  • the connecting means spans an open channel, this being the support surface.
  • the end frame members may be connected to the hub member by connecting means comprising a biassing means, such as, for example, a flexible elastic tube or the like, or a helical coil spring, whereby the end frame members are biassed towards the erect position.
  • a biassing means such as, for example, a flexible elastic tube or the like, or a helical coil spring
  • the end frame members are preferably elongate members and may comprise tubes, rods or the like.
  • the end frame members may have uniform or different dimensions from one another.
  • the end frame members may be formed from any rigid material, for example, metal, wood, carbon or rigid plastics.
  • the end frame members may be substantially circular in cross section.
  • the end frame preferably comprises at least three end frame members, and most preferably comprises at least four end frame members.
  • the end frame members may be disposed substantially regularly around the interconnecting hub member, although a wide variety of different arrangements are possible.
  • end frame members are disposed about the hub member in two sets of opposing pairs of end frame members, whereby the end frame members describe generally a cross shape in the erect position when viewed from an end.
  • the end frame members may be disposed regularly around the hub member such that the second ends of uniformly sized end frame members will describe an approximate square.
  • the relative angles between pairs of end frame members may be altered such that the aspect ratio of the rectangular shape described by the second ends of uniformly sized end frame members may be altered.
  • the shapes described by the second ends of the end frame members may be generally regular or irregular polygons. Provided that sufficient rigidity can be established by the locking of a lesser number of the end frame members, certain of the end frame members may be attached to the hub member without the need to be locked by the locking means, thereby reducing the necessary complexity and size of the hub member.
  • the hub member may therefore be provided with additional anchorage points for further end frame members.
  • these may comprise grooves or channels in the hub member in which the end frame member(s) may be accommodated.
  • each corner joint may comprise a rivet about which relative rotation of the end frame member and side frame member can occur.
  • each corner joint comprises a 'U'-shaped bracket with a securing pivot screw or pin.
  • the end frame members preferably fold inwardly towards the side frame members about the corner joints to take up the collapsed position and fold relative to one another about the hub member.
  • the ratio of the length of the side frame members to the length of the end frame members is at least 2:1, such that sufficient space is provided for collapse of the frame assembly by inward folding of the end frame members of each end frame toward the side frame members.
  • this ratio can be reduced.
  • the first and second end frames are preferably substantially mirror images of one another, such that interconnecting side frame members extending between the second ends of corresponding end frame members are generally parallel to one another. It will be appreciated, however, that a range of other configurations are possible in which the first and second end frames differ in size and/or shape.
  • the side frame members may be sleeved to allow the size of the collapsed frame assembly to be minimised.
  • the sleeved side frame members each comprise at least two sections, an inner section and an outer section, the inner section being slideable within the outer section (or “sleeve").
  • the effective length of the sleeved side frames may therefore be increased or reduced by sliding of the inner section within the outer section.
  • the inner and outer sections are preferably releasably fixable relative to one another, and in particular are preferably releasably fixable in the position giving maximum extension of the sections relative to one another.
  • the inner and outer sections may be fixed using an appropriate locking mechanism such as, for example, a sprung pin or a rotating lock.
  • end frame members may be sleeved in order to minimise the size of the collapsed frame assembly.
  • a collapsible enclosure comprising a foldable frame assembly as hereinbefore defined to which a cover means is secured.
  • the cover means may be secured to the frame assembly in any suitable manner, and may be secured to the frame assembly either prior to or after erection thereof.
  • suitable means of attachment include zips, fixed or elasticated ties, stitching or heat-sealing.
  • the cover means may be permanently secured to the frame assembly to provide a unitary collapsible enclosure. This has the advantage of mimmising the risk of losing the cover means during transit or storage.
  • a flexible cover means is preferably secured to the frame assembly, although in some situations it may be desirable to use a rigid cover means.
  • the cover means may be formed from any suitable material, including, for example, cotton, nylon, plastics, etc.
  • the material may be coated or treated, for example to render said material waterproof.
  • the cover means may have sections formed from different materials to allow, for example, the passage of light or air.
  • the material chosen for the cover means will typically reflect the intended use of the collapsible enclosure.
  • the collapsible enclosure may be used as a collapsible greenhouse or cold frame, in which case a transparent material will be secured to the frame assembly.
  • Material such as canvas may be used to form the cover means of a collapsible enclosure of the present invention for use as a tent, shelter, etc.
  • the cover means may form a continuous enclosure around the frame assembly.
  • selected sections such as selected planes of the erect frame assembly may not be covered by the cover means.
  • a ground-facing plane of the erect frame assembly may conveniently be left uncovered.
  • the cover means may be provided with one or more openings.
  • the collapsible enclosure according to the present invention has a wide range of different applications, including those mentioned above. Other applications include, but are not restricted to, an emergency/disaster tent, a fisherman's tent, a workman's tent/manhole cover, a birdwatcher's "hide", a sport spectator's tent/dugout, a collapsible cot/playpen, an internal storage means, a temporary wardrobe, an external storage means, a temporary shed, a vehicle cover, a plant equipment cover or similar.
