The present description relates to improvements in racks for carrying sports equipment alongside a personal watercraft. More specifically, the present description relates to a clamp of the rack.
Personal Watercraft (PWC) are enjoyed for sport and recreation. PWC may also be used in sea rescue and policing. It may sometimes be convenient to carry equipment, such as sport or rescue equipment, on the PWC.
PWC have limited space or holders to carry equipment, especially bulky sports equipment such as surfboards or fishing rods. Carrying frames which bolt onto PWC are known, but these frames have to be customized for specific PWC makes and models. PWC owners may also not want a rack that bolts to the PWC given the permanent nature of bolting a rack to the PWC.
In one aspect there is described a rack for carrying sports equipment alongside a personal watercraft. The personal watercraft has a hull and a lip extending along a top portion of the hull. The rack includes a clamp sized and configured to engage the lip of the personal watercraft, the clamp having a first engagement surface configured to engage an outwardly-facing portion of the lip, the clamp having a second engagement surface configured to engage an inwardly-facing portion of the lip, the second engagement surface being retractable relative to the first engagement surface. The rack includes a carrier extending from the clamp, the carrier having a length, a height, and at least one generally U-shaped engagement surface configured to hold an article of sports equipment.
In another aspect there is described a clamp for attaching an equipment carrier alongside a watercraft having a hull. The clamp includes a first engagement surface configured to engage an outwardly-facing portion of the hull. The clamp includes a second engagement surface moveably connected to the first engagement surface, the second engagement surface being configured to move towards the first engagement surface to clamp a portion of the hull therebetween. The clamp includes a third engagement surface moveably connected to the first engagement surface, the third engagement surface being moveable relative to the first engagement surface to adjust a clamping angle of the first engagement surface and the second engagement surface relative to the hull of the watercraft.
The second engagement surface may be generally L-shaped.
The first engagement surface may include an aperture configured to receive a portion of the second engagement surface therethrough. The aperture may be a slot. The first engagement surface may be formed as a plate.
Movement of the first engagement surface and the second engagement surface towards each other may require rotation. Rotation may be about an axis parallel to a central longitudinal axis of the aperture or slot.
The clamp may include a turn knob configured to engage a portion of the second engagement surface to move the second engagement surface towards the first engagement surface.
The first engagement surface may be generally L-shaped. The first engagement surface may have a foot portion and an upper free end. The upper free end may be an angled flange. The foot portion may be configured to adjustably engage the third engagement surface.
The third engagement surface may have a length with a free end at one end thereof. The free end may include a foam or rubber hull engagement surface. The third engagement surface may include at least one aperture for receiving a fastener to removeably fasten the third engagement surface to the first engagement surface. The third engagement surface may be a plate having a length and a width. The at least one aperture may be a slot or a series of holes extending perpendicular to the length of the third engagement surface. The third engagement surface may be moveable in a direction generally parallel to the direction of movement between the first engagement surface and the second engagement surface. The first engagement surface may include an aperture configured to receive a projection of the second surface therethrough. The projection may have a central longitudinal axis, the fastener having a central longitudinal axis generally perpendicular to the central longitudinal axis of the projection when the fastener is engaged with the first engagement surface and the third engagement surface.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed. In the present specification and claims, the word “comprising” and its derivatives including “comprises” and “comprise” include each of the stated integers, but does not exclude the inclusion of one or more further integers.
The claims as filed and attached with this specification are hereby incorporated by reference into the text of the present description.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the invention and together with the description, serve to explain the principles of the invention.

Clamp 10 includes a bracket 12, a moveable jaw 14, an adjustable bumper formation 16, and turn knobs 18.
Bracket 12 is preferably generally L-shaped in end profile view, as shown in
Foot portion 20 includes two spaced apart feet 30. Each foot 30 has a flat base plate 32 and a web 34 which extends from a proximate end of base plate 32. Base plate 32 and web 34 are generally square relative to each other. Each web 34 extends between one of the base plates 32 and angled flange 26.
Webs 34 each include an aperture in the form of an elongate slot 36. Slots 36 extend between respective base plates 32 and angled flange 26. Slots 36 have a longitudinal axis which is perpendicular to the direction of the elongation of slot 36.
Each base plate 32 has a pair of spaced-apart threaded holes 38. Holes 38 are internally threaded for receiving and engaging a shank of a threaded fastener such as a screw.
Upper free end 24 includes a pair of upright ears or mounting flanges 40. Mounting flanges 40 are integrally formed with angled flange 26. Mounting flanges 40 have spaced holes 42 therein for receiving fasteners such as bolts 44.
Bracket 12 may be formed from a flat plate which is cut and bent to shape or may be moulded from plastics or composite material. Bracket 12 may be aluminium or stainless steel material, or can be of other suitable materials such as plastics materials, fibreglass reinforced materials, or carbon fibre-based materials. Foot portion 20, angled flange 26 and mounting flanges 40 are all integrally formed with each other.
Different types of equipment carriers may be fastened or bolted onto bracket 12 by being mounted to flanges 40. Bracket 12 is not limited to any particular type of carrier and different carriers may be interchanged for different purposes. Some example carrier types include a U-shaped carrier as described in more detail with reference to

Arms 50 have portions which are threaded. Turn knobs 18 screw onto the threaded portions of arms 50.
As shown in
Other mechanisms may be used to move jaw 14 relative to bracket 12. For example, bracket 12 may have a series of internally threaded holes rather than slots 36. Arms 50 may screw into the holes and be rotatable relative to grip formation 52. Rotating the arms by means of a finger grips or a hand tool may then move or displace jaw 14 relative to bracket 12.
As shown in
In another embodiment, jaw 14 may include two separate arms 50 which are not connected by grip formation 52. Each arm 50 will then have the tab 56 at its distal end and be displaceable separately from the other arm 50.
Referring to
Bumper formation 16 can slide forward or backwards relative to base plates 32 to extend and retract bumper formation 16 by selecting different holes 68 to be in register with holes 38 in base plates 32. That is to say that the extension of bumper formation 16 from base plates 32 can be set at increments being the spacing between holes 68. Bumper formation 16 moves in a direction generally parallel to the direction of travel of jaw 14 when clamping clamp 10 to a lip of the watercraft. Bumper formation 16 can be offset from side to side by selecting different series of holes 68 in slider plate 62 to be in register with holes 38 in base plates 32. Bumper formation 16 may also be angled in a plane parallel to the plane of the base plates 32 by particular selection of holes 68 in slider plate 62 to be in register with holes 38 in base plates 32.
Having described the preferred components of clamp 10, a preferred method of attaching clamp 10 to the side of a personal watercraft will now be described with reference to
PWC 80 has a lip 82 which extends along the sides of PWC 80. Lip 82 is formed where a hull 84 of PWC 80 is attached to a deck 86 of PWC 80. Lip 82 extends along a top portion of hull 84.
Clamp 10 engages lip 82 by clamping to lip 82. As a first step, clamp 10 is mounted to lip 82 with first engagement surface 28 below angled flange 26 contacting rounded upper surface 85 of outwardly facing portion 90 of lip 82. Third engagement surface 66 of bumper bar 64 is positioned against hull 84. Turn knobs 18 are rotated to move jaw 14 towards bracket 12 to clamp lip 82 therebetween as shown in
First engagement surface 28 of bracket 12 and third engagement surface 66 of bumper formation 16 are urged against lip 82 and hull 84, respectively, as jaw 14 tightens against inwardly facing portion 88 of lip 82. Clamp 10 thus positively engages PWC 80 at three points of contact to provide firm, stable attachment of clamp 10 to lip 82.
Bumper formation 16 stops bracket 12 from rotating off lip 82 as jaw 14 is tightened. The clamping angle at which clamp 10 is clamped to lip 82 can be adjusted by adjusting the extension of bumper formation 16.
Clamp 10 is adjustable to fit many different sizes and configurations of a PWC lip. Bumper formation 16 is adjustable to set a desired clamping angle as described above. Arms 50 of jaw 14 can move up-and-down and in-and-out of slots 36 to be adaptable to clamp to the inside of different lip configurations and sizes.

Bracket 212 is generally L-shaped in end profile view, as shown in
Referring to
Jaw 214 includes a single arm 250 having a free end and a grip formation in the form of a transverse tab 256 at the other end. A second engagement surface 258 is defined along the inside of tab 256.
Jaw 214 is displaceable by rotating turn knobs 218 in the same manner as described for jaw 14.
Bumper formation 216 includes a slider plate 262 and a bumper bar 264 at a distal edge of slider plate 262. A third engagement surface 266 is defined on the outside of bumper bar 264. Referring to
Clamp 200 does not show a mounting formation, such as mounting flanges 40 of clamp 10, to secure a carrier to clamp 200. It will be appreciated that a suitable mounting formation may be fixed to clamp 100 or integrally formed with bracket 212. For example only, free end 224 may have a number of holes for receiving bolts to bolt a carrier to bracket 212.
Clamp 200 engages a lip 282 shown in
Clamp 302 includes an outer leg 306 and an inner leg 308. Legs 306, 308 are connected by a base 310, which forms the base of carrier 304. Outer leg 306 includes a moveable arm 316. Arm 316 includes a foot 320 at one end and a finger grip 322 at the other end. Arm 316 screws into outer leg 306 to be able to move in a direction transverse to the extension of leg 306. Foot 320 defines a first engagement surface 318 which engages outwardly facing portion of hull 84.
Inner leg 308 includes an arm 330 extending to an inwardly facing portion of hull 84. Arm 330 includes a foot 332 defining a second engagement surface 334. Clamp 302 is clamped to the hull 84 by displacing arm 316 to urge against the outside of hull 84, thereby clamping a portion of hull 84 between legs 306, 308. Base 310 rests on top of lip 82, though it will be appreciated that it may be spaced-apart if desired.
Carrier 304 includes two U-shaped channels 340 defining two generally U-shaped engagement surfaces 342 configured to hold sports equipment. The two U-shaped channels 340 are side-by-side, divided by a common post or wall 344.
Jaw 404 has two spaced apart threaded holes 414. Top plate 406 includes two holes (not shown) which align with holes 414 in jaw 404. Clamp 402 includes two screws 416 which pass through the holes in top plate 406 and screw into threaded holes 414 in jaw 404. Screws 416 have heads 418 which bear against the outside of top plate 406. Heads 418 are configured to be rotated by hand.
Continuing with reference to
Clamp 402 is clamped to lip 82 by rotating screws 416 so that top plate 406 and jaw 404 are urged towards each other, clamping lip 82 between shoulder 424 and a foot of jaw 404. Top plate 406 is configured to follow the contour of the top of lip 82 in order to facilitate gripping onto lip 82.
Clamps 10, 200 each provide a simple and secure way of carrying accessories on a PWC. Many different types of carriers can be mounted the PWC using the universal mounts provided by flanges 40. The three engagement surfaces provide at least three points of engagement where each clamp urges against the PWC when clamped to the lip to provide a rigid and secure attachment.
It will be appreciated that the clamp may be used to mount a wide variety of equipment to a PWC. For example only, the clamp may be used to mount racks, holders, frames, carriers, adapters, or anything else a user may want to mount to the PWC.
The clamp may also be used to mount carriers to other types of personal recreational craft or transport, other than PWC. The clamp may clamp a carrier to any personal transport having a lip or a lip-like formation. For example only, the clamp may clamp to the lip or lip-like formation of a snowmobile, boat, all-terrain vehicle, motorcycle, bicycle, vehicle roof, or any other personal transport.
The foregoing description is by way of example only, and may be varied considerably without departing from the scope of the present disclosure. For example only, the shape of the bracket may be formed in a variety of ways (e.g., any number of feet 30 and any number or shapes of mounting flanges 40.) The carrier may have any number of engagement sockets or grooves. The carrier may be fixed to the clamp in any number of ways, including being welded together, integrally formed together, bolted together or clipped together. The carrier may have any shape or configuration of engagement surface for supporting different types of articles that may be carried. The carrier may have hooks, slots, grooves, sockets, channels, posts, spigots, apertures, straps, walls, brackets, collars or other engagement surfaces. Each clamp may support any number of carriers, for example one carrier as shown for rack 130, two carrier as shown for rack 100, or any other number of carriers. The clamp may support a carrier or frame between spaced apart clamps. For example, two or more clamps may be attached to opposite sides of PWC and a carrier in the form of a carrier frame or rack may extend across PWC from the one side to the opposite side to be supported by clamps. The rack may support equipment above the deck of a personal watercraft.
