Definitions

  • This invention relates to portable structures intended to provide shelter from the weather elements.
  • Structures of this type are well-known for use by riverside fishermen to protect the users from exposure to wind, rain, snow and generally they take the form of a large umbrella. More recently, developments have taken place in the design of such umbrella whereby it has been possible to eliminate the need for a central pole or shaft whereby the user has been unimpeded by such a shaft in pursuit of his fishing activities.
  • Patent Specification GB-A-2 237 193 is an umbrella-like structure provided with a number of canopy-supporting ribs pivotally mounted on a hub member.
  • a pressure plate is located onto a threaded stud and caused to apply pressure to the ribs in order to maintain the umbrella in opened operative position, by means of a nut which is normally tightened on to the stud.
  • the pressure plate replaces the conventional rib-supporting struts which depend outwardly from a sleeve slidable along the central shaft.
  • a portable structure having no central pole or shaft and comprising a canopy and a plurality of umbrella ribs pivotally mounted to a central hub and pivotable between a storage position and a canopy tensioning position, wherein the canopy is fastened to the ribs, has a radial slit provided between one pair of adjacent ribs and includes means for releasably joining together the edges of the slit.
  • the means for joining together the edges of the slits may comprise a slide fastener, or alternatively hook and loop type fastening means or hook and eye type fastening elements may be provided.
  • the central hub is preferably formed with a profile against which selected ribs are held in tension when the canopy is in its erected condition.
  • the ribs may vary in thickness along their length in order to allow of varying degrees of bending of the ribs as the canopy is placed under tension. They may taper from a thicker dimension adjacent the hub to a narrow dimension adjacent the periphery of the canopy. Alternatively, the ribs may comprise two or more axially aligned components, jointed together and of differing thicknesses.
  • the structure may comprise a series of umbrella ribs pivoted to the central hub so as to be able to be gathered together centrally for storage and carrying purposes.
  • the ribs are pivoted outwards from their stowed position to beyond the conventional "umbrella erected" position.
  • the umbrella reverses or inverts.
  • the arrangement whereby the ribs are pivoted to the central hub should permit such inversion.
  • the hub should be constructed so that the ribs can pivot beyond their mid-point position to an inclined position suitable for the erected form of the umbrella or canopy.
  • the hub may have suitably profiled surfaces for this purpose.
  • Sheet material of which the canopy is made should permit the inversion movement, being attached to the ribs but having the radial slit between said pair of ribs, the slit being openable and closable by closure means such as a zip.
  • the ribs are moved between the positions discussed above. In the open position of the canopy, the assembly is effectively retained in this configuration by the tension in the canopy itself which has been set up when the zip is zipped up, and this tension holds the ribs against the profiled surfaces of the hub.
  • the structure is preferably capable of single-handed erection and collapsing. Moreover, the reverse arrangement of ribs and canopy have the result that the collapsed configuration of the ribs and their erected configuration are effectively on opposite sides of the central mean plane. Additionally, the use of the slit and fastener enables not only securing but also tensioning of the canopy.
  • a portable structure comprises a frame 2 including a number of ribs 4 pivotally mounted at their innermost ends on swivel pins 6 by means of ferrules 8 to a hub 10 as seen clearly in Figures 5 and 7.
  • the outermost ends of the ribs 4 are located in pockets 12 sewn to a canopy 14.
  • the ferrules 8 are pivotable through approximately 90 degrees upwardly about pins 7 fast in the swivel pins 6 as seen in chain lines in Figure 7 and the swivel pins 6 are rotatable through approximately 180 degrees about their own axes.
  • the ribs may pivot through about 180 degrees with respect to their mountings on the hub 10 and through about 90 degrees about their pins 7 to fold upwardly to the collapsed position illustrated in Figure 6.
  • the canopy 14 comprises a number of separate panels joined together by seams adjacent the ribs 4.
  • panels 16 and 16A are substantially identical in size and shape.
  • Panels 18 are about one half size of the panels 16 and are provided on their innermost radial edges with a slide fastener 20 ( eg a "zip" fastener).
  • a slide fastener 20 eg a "zip" fastener
  • Alternatively a hook and loop fastener or hook and eye fasteners may be provided.
  • each pair of panels 16A and 18 may be formed as one complete panel, ie not joined by a seam.
  • two further panels 22 are provided and are joined by seams 24 to the panel 16A.
  • Two adjacent ones of the ribs 4 are formed as poles 28 and 30 and the panels 18 are formed adjacent the slide fasteners 20 with hems 26 to receive the poles 28 and 30, see particularly Figures 8 and 9.
  • the pole 28 is formed at its bottom end with a point 32 which may be pressed into the ground, and a wire loop 34 is provided to clip the outer ends of the poles 28 and 30 together when the structure is erected with the canopy in its tensioned condition.
  • the wire loop relieves the fastener 20 of some of the possible strain.
  • a pair of poles 36 are pivoted at each of their upper ends to those pockets 12 adjacent the joining seams of panels 16 and 16A, and pass downwardly through retaining loops 38 on the panels 22.
  • the poles are formed with points 40 at their lower ends which may be pressed into the ground to maintain the panels 22 in position as seen particularly in Figure 1.
  • ribs 4 In order to cause the ribs 4 to flex to a greater degree towards their outermost ends than that adjacent the hub, they may be tapered, lessening in diameter towards their outermost extremities. Alternatively they may be formed from two separate rods joined approximately mid-way of their length, the innermost section being of greater diameter than the outermost section.
  • the hub 10 is formed with a flange 11 (see Figures 5 and 7). part of the flange has a level face 13 which restricts the downward component of pivotal movement of the ferrules 8 and the ribs 4 before bending of the ribs is effected. A different part of the flange is machined to provide an angled face 15 to allow a greater degree of pivotal movement of the ferrules connecting with the lower ribs 4 and the poles 28 and 30.
  • the ribs 4 may be of lightweight plastics or metal rod, or of fibre glass or carbon fibre.
  • the portable structure according to the invention can be erected speedily and simply, can provide a stable and efficient shelter having no restrictions caused by a central pole or shaft associated with other known arrangements and has few separate components.
  • the canopy shape combined with the profile of the hub and the flexibility of the ribs determines the final shape of the structure and the essential feature which allows it to work and erect simply is the split in the cover which can be joined by the slide fastener.
