Definitions

  • the present invention relates to a breakable joint as specified in the preamble of Claim 1, namely a joint comprising two parts which are pivotably connected to one another so that they can be moved relative to one another about the pivot from a folded position to an open position, in which an end portion of one of the parts is received in a mouth portion of the other of the parts, and a slidable locking member arranged on or constituted by the said mouth portion or the said end portion, the locking member being slidable in a direction which is transverse of the pivot axis from a retracted position, in which it permits the said end portion to be received by the mouth portion, to a forward position, in which, with the said end portion located in the mouth portion, it inhibits subsequent movement of the two parts about the pivot into the folded position until the locking member is retracted, the locking member being urged by resilient means into its forward position so that as the said two parts are moved about the pivot from the folded position to the open position, the locking member initially abuts the mouth portion or the end portion so that
  • the locking member is arranged on the said end portion.
  • joint is disclosed in co-pending European Patent Application EP-A-1 310 616 in the name of Fox Design International Limited.
  • the joint is used to join sections of a tent frame together, although it will be appreciated that the joint may be used in other applications where two elongate sections are folded together for storage, and opened outwardly for use, for example in various kinds of stands and supports.
  • An aim of the present invention is to obviate this disadvantage.
  • the present invention provides a joint having the features set out in the opening paragraph of the present specification in which a selectively operable catch is provided on the joint to enable the locking member to be held in its retracted position, against the force of the resilient means, when it is desired to avoid accidental locking of the said two parts in their open position.
  • the catch may be so constructed that it is slidable between a locking position and a non-locking position.
  • the catch may be provided with a thumb-engageable portion on the outside of the locking member, and an abutment portion on the inside of the locking member, there being a further abutment portion on the said end portion which engages the abutment portion of the catch when the latter is in its locking position and the locking member is in its retracted position.
  • a slanting portion may be provided on the catch and/or on the said end portion to urge the catch into its non-locking position when the locking member is moved from its forward position to its retracted position.
  • the present invention extends to a tent or canopy having a frame which is collapsible and erectable by means of at least one joint made in accordance with the present invention.
  • a breakable pivot joint 10 shown in Figures 1 to 7 comprises two generally tubular joint parts 12 and 14 to which are connected, when in use, two respective ends 13 and 15 of tent-frame rib or bar sections. These sections may be tubular and made of aluminium, and are connected and secured to their associated joint parts 12 and 14 by a combination of a tight fit of respective ends of the rib or bar sections within the tubular parts and by screws through screw holes 16 and 18 and corresponding holes in the ends 13 and 15. The location of such holes in the rib or bar sections, and other holes (not shown) at their other ends can be used to ensure that further joints at those other ends are correctly oriented in relation to the illustrated joint to facilitate folding-up of the assembly.
  • the parts 12 and 14 have respective tubular portions 12 a and 14 a . These have respective axes at about 140° to one another when they are in their relative open position as shown in Figure 1 .
  • the joint parts 10 and 12 are each also provided with a hook-like clip 20 from which may be suspended sheeting material of a tent.
  • the two joint parts 12 and 14 are pivotablly connected together by means of a pivot 22 which has a transverse turning axis offset from the axes of the tubular portions 12 a and 14 a .
  • the joint part 12 has a female retaining portion or mouth portion 24 which opens towards the joint part 14 as shown in Figure 2 .
  • the joint part 14 has a corresponding end portion 26 or male retaining portion which is received in the mouth portion 24 of the joint part 12.
  • a locking member in the form of a slider 28 has a thumb-pad 30, extending around the outside of the end portion 26 of the joint part 14, and an inner serrated portion 32 which is immediately adjacent to the said end portion or male retaining portion 26. Corresponding serrations on the said end portion or male portion 26 engage the serrations of the slider 28.
  • the said end portion or male portion 26 is so dimensioned and positioned in relation to the pivot 22 and the mouth portion 24 that a gap 34 is present between the mouth portion 24 and the said end portion 26 on the pivot side of the joint 10. Furthermore, a lower portion 36 which extends from and is integrally moulded with the slider 28 is urged towards the part 12 by a helical compression spring 38 provided in a spring cavity 40 of the joint part 14. As a result, parts 12 and 14 may be opened further until the gap 34 is closed and the mouth portion 24 no longer abuts the slider 28. The slider 28 may now be pulled outwardly from the mouth portion 24 against the restoring force of the compression spring 38. This enables the whole joint 10 now to be folded by pivoting the joint parts 12 and 14 relative to one another about the pivot 22 until the end portion 26 is entirely clear of the mouth portion 24.
  • a catch 42 is provided on the slider 28.
  • the catch 42 comprises a thumb-engageable part 44 on the outside of the slider 28 and an abutment portion 46 on the inside of the slider 28.
  • the parts 44 and 46 of the catch 42 are connected together by a neck portion 48.
  • the neck portion 48 extends through a slot 50 provided in the slider 28. This slot has a widened end portion 52 to facilitate insertion of the abutment portion 46 through the slot 50. This slot is shown most clearly in Figure 6 .
  • That part of the end portion 26 which is underneath the slider 28 is shown most clearly in Figure 5 . It is formed with a recess 54 engaged by the abutment portion 46 of the catch 42 when the latter is in its locking position and the slider 28 is in its retracted position. It can be seen in this position that an abutment surface 56 on one side of the recess 54 abuts the abutment portion 46 of the catch 42.
  • the end portion 26 is provided with a slanting surface 58 which meets the abutment surface 56.
  • the abutment portion 46 of the catch 42 is also provided with slanting surface 60.
  • Movement of the catch 42 in the other direction will now bring the abutment portion 46 thereof into position within the recess 54 to hold the slider 28 in its retracted position until the user engages the thumb-engageable part 44 of the catch 22 with his or her thumb to move the catch back to its unlocking position.
  • a canopy shown in Figures 8 and 9 comprises a frame 80 comprising a plurality of joints 10, each of which has the construction illustrated and described with reference to Figures 1 to 7 . These joints 10 interconnect a series of rod sections 82 to form a series of arches spanning two spaced-apart support hubs 84 and 86. The canopy cover is attached by loops (not shown) to the hooks 20 of the joints 10.
  • the joints are unlocked in the manner described herein so that the canopy frame can be folded-up substantially as shown in Figure 9 .
  • the catch 42 of each joint 10 is shifted to its locking position while the slider 28 is in its retracted position. This retains the slider 28 in its retracted position. The catch 42 is shifted back into its unlocking position when it is desired to re-erect the canopy.
  • the locking slider 28 may be arranged on the mouth portion 24, on the inside thereof, instead of on the said end portion 26.
  • the tubular portions 12 a and 14 a of the parts 12 and 14 may have respective axes which are at a different angle to the one illustrated, or indeed they may be co-linear.
