Definitions

  • the option of stowing the dinghy on deck may be problematic due to constraints of space on the deck of the boat and the difficulty of lifting the dinghy onto the deck.
  • the only way to stow the dinghy on deck may be to use a lightweight inflatable with collapsible floors and to remove the outboard motor before lifting the dinghy on deck.
  • this arrangement is problematic if the dinghy needs to be launched in rough weather conditions. In such cases, it is preferable to have access to a rigid-floored dinghy made from a heavyweight material that has been stowed with the outboard motor already attached and immediately usable.
  • the further slider being slidably connected to the further shaft, such that the further slider is able to slide along at least part of the length of the further shaft; wherein the slider and the further slider are connected by a cross-member.
  • the further shaft has one or more of the features of the shaft, preferably all the features of the shaft.
  • the further slider has one or more of the features of the slider, preferably all the features of the slider.
  • the separation of the arms may be adjusted by securing the sleeve at the required position along the length of the cross-member, e.g. by means of one or more stops positioned on the cross-member at either side of the sleeve.
  • the one or more stops may additionally limit the rotation of the arm about the cross-member to a desired range.
  • the sleeve may comprise a protrusion extending in a longitudinal direction.
  • a guide rail provided on the other of the slider and the shaft, the guide rail having a neck portion that supports a head portion; wherein the bracket comprises a channel that accommodates the head portion of the guide rail and two retaining elements that extend around the head portion of the guide rail so as to retain the head portion of the guide rail within the channel.
  • the bracket is provided on the slider and the guide rail is provided on the shaft.
  • the mounting block comprises a first element that is pivotally connected to the shaft and a second element for contacting the surface of the second boat, a spacing element being optionally provided between the first and second element, wherein the second element is in abutting non-bonded contact with one of the first element and the optionally provided spacing element.
  • the first and second elements and the optional spacing element may be bolted together.
  • the present invention may provide a boat on which is mounted a framework according to the first aspect of the invention.
  • the framework may comprise one or more of the optional features of the framework according to the first aspect of the invention.
  • the boat is typically a sailing yacht.
  • Figure 9a shows a schematic perspective view of a collar of the arrangement of Figure 8
  • Figure 9b shows a schematic perspective view of the sleeve of the arrangement of Figure 8
  • Figure 9c shows a schematic perspective view of another collar of the arrangement of Figure 8;
  • Figure 19 shows a schematic front elevation view of the framework of Figure 1 , in which the framework is supported by halyards and a dinghy is suspended from it;
  • Figure 30 shows a schematic perspective of the base plate of the mounting block to be used in conjunction with the bracket shown in Figure 27, and illustrates the extra rubber base plate utilised:
  • Figure 36 shows a cross sectional view taken along the lines II of Figure 33, where the slider is at the free end of the shaft:
  • Figure 47 is a schematic perspective of a locking plunger assembly being part of the further and better alternative slider as shown in Figure 42:
  • Collar 36 has an aperture 36b having serrated edges, along with a corresponding aperture (not shown) located diametrically opposite.
  • the serrated edges allow collar 36 to provide multiple overlapping square slots than can each receive the square-shouldered bolt that fixes collar 36 to cross-member 20.
  • collar 36 may be positioned on cross-member 20 at range of orientations. This allows the limits of rotation of arm 22a about cross-member 20 to be fixed as required.
  • Shaft 14a comprises a stainless steel tubular portion 40 that is aligned with and affixed to an extruded aluminium guide rail 42 by means of screws 43.
  • the guide rail has an enlarged head portion 44 that is connected to the tubular portion 40 by means of a neck portion 46.
  • a tang 97 comprising an offset plate 98a and a wire rope compression block 98b grips the backstay wire 99 and provides a point to which either a pulley or a shackle will be attached.
  • the backstay arrangement comprises either only one connection to the mast, or where the adjustable lower V section merges to a single connection above.
  • the dingy halyard is thus kept away from the backstay being the furthest aft fixed rigging.
  • a spreader bar 106 may optionally be provided in certain installation modes.
  • the sliders 16a,b are at the distal ends of the shafts 14a,b from the mounting blocks 12a,b.
  • a halyard 102 that is connected to a windlass and optionally a cleat or clutch (not shown) may assist in counteracting the load of the dinghy.
  • the framework is additionally be secured to the pushpit railing 1 10 by means of a securing mechanism e.g. as shown in Figure 21 .
  • the sliders may be held in place by means of respective movable plunger stops (feature 58 of Figure 1 1 ).
  • the upper pushpit rail may at the user's discretion itself be reinforced by adding some structural supports should it be felt to be of poor structure. Such structural supports are known in the art, for example, as supplied by Kato MarineTM.
  • Position C is an intermediate position during deployment of the framework to launch the dinghy 100.
  • the arms 22a,b are lowered by operating the windlass to loosen the halyard 102.
  • the mechanism securing the framework to the pushpit railing 1 10 (see Figure 21 ) is also released.
  • the framework 10 is lowered towards the waterline, until the shafts 14a,b extend in a slight downward direction from mounting blocks 12a,b. This causes the sliders 16a,b to slide towards the ends of the shafts 14a,b distal from the mounting blocks 12a,b.
  • the framework is readily demountable from the boat by the removal of hinging pins 54 (see Figure 14), the holding pins securing the shafts to the pushpit railing (if used) and the shackles connecting the arms to the windlass.
  • the framework is then reducible to individual elongate elements for storage, by disconnecting the cross-member 20 from the sliders 16a,b, and removing the bolts from the collars located outwardly from arms 22a,b.
  • the second component has all the features of the first component, except that the male component of the buckle is substituted with the female component.
  • 1 16a has fixing holes along its full-length allowing the two carriages 148a and 148b and the crossmember mounting tube 161 to be located in a variety of longitudinal positions or sequences, the variation of which effects the carrying height of the dinghy in either the carriage or elevated position and the full travel of the slider upon the shaft.
  • Figure 42 demonstrates the default normal position able to be changed by the user.
  • the locking plunger 162 is contained in a welded housing at the mounting block end of the slider and is shown in the engaged position with the plunger rod inserted into 1 14a thus preventing motion of the slider with respect to the shaft when the shaft is in the upright position and there would be a downward force upon 161 due to the weight of the dinghy, which the engagement of 162 would secure against possible rigging failure or accidental operation of switches permitting accidental fall or lowering of the dinghy.
