The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights whatsoever.
- 1. Field of the Invention
- The present invention relates to a launch and retrieval apparatus for a personal watercraft.
- 2. Description of Related Art
- In the past two decades, personal watercrafts, which are small self-propelled vessels for one or two people, have become common place on lakes and waterways of developed countries. A personal watercraft may be viewed as the water borne equivalent of a motorcycle. The most popular personal watercrafts are propelled by high powered jets of water generated by pumps driven by small engines such as those marketed under the trademark, Jet Ski.
- To prolong their life and minimize their maintenance, it is desirable to remove personal watercraft from the water when they are to be stored or not to be used immediately. Often they are stored on a dock at the body of water where they are used or transported to a protected area. However, personal watercrafts typically weigh over 400 pounds and require a lift or specially configured small boat trailer to remove them from the water. Watercraft lifts and trailers are well known in the art as exemplified in U.S. Pat. Nos. 5,184,913 and 6,637,975.
- The personal watercraft launching and retrieving apparatus taught herein facilitates launching a personal watercraft from a flat bed vehicle, such as a pickup truck, into a body of water for use, and retrieving it back onto the vehicle from the water after use. The apparatus promotes rapid launching and retrieving while avoiding the inconvenience of towing and maneuvering a personal watercraft trailer. The present apparatus comprises:
-
- 1) a personal watercraft supporting, rectilinear assembly having two equal length, parallel rails, with two or more lateral cross braces affixing the spatial relation of the rails that are separated by a distance so that the two rails provide stable support for the watercraft, and having;
- 2) a ramp assembly comprised of one or more additional rectilinear, watercraft supporting subassemblies each having two equal lengths, parallel rails, separated by a distance substantially equal to the distance of separation of the support assembly, and having two or more lateral cross braces affixing the spatial relation of the rails;
- wherein the rails of the ramp of the watercraft-supporting assembly are attached by a pivoting means to the corresponding rails of the support assembly and, in turn, each ramp subassembly is attached by similar pivoting means to the subsequent ramp subassembly, and wherein the pivoting means may be locked in position to affix the relationship of each subassembly to its adjacent subassembly; and
- 3) a winching means to facilitate launching and retrieval of the watercraft.
- The personal watercraft is typically for one or two people and it is jet powered. One example of such as a personal watercraft for which the present apparatus may be employed is the Jet Ski (trademark) watercraft. However, the apparatus may also be used for substantially any small boat, e.g., sailboats, rowboats, and the like, so long as it can safely fit on the apparatus's support assemble. The apparatus enables one person to launch and retrieve a personal watercraft and transport, store, and maintain that watercraft securely on the bed of a pick-up truck.

FIG. 1 a is a top elevation view of the present invention, i.e., the personal watercraft launching and retrieving apparatus 2 (hereinafter “apparatus 2”), mounted on the bed (cargo floor) 4 of atruck 6.FIG. 1 b is the corresponding left side elevation view. The features and mode of operation ofapparatus 2 can best be understood by considering bothFIGS. 1 a and 1 b together. Further, for clarity inFIG. 1 b, only newly mentioned items or those useful for orientingFIG. 1 b with respect toFIG. 1 a have been labeled. For items not explicitly labeled inFIG. 1 b, refer toFIG. 1 a. Whileapparatus 2 may be mounted on a dock or static, shore side platform, conveniently it is mounted to the bed of substantially any small or medium size truck. Even more conveniently, it is mounted to the bed of a pick-up truck having nominal bed length of at least about 6 ft (1.8 m) or the floor of a van having sufficient cargo capacity for the small watercraft andapparatus 2. - In
FIGS. 1 a and 1 b,truck 6 is a standard (domestic or imported) pick-up truck with the side panels and tail gate not shown in the figures (but noted by dashed lines inFIG. 1 b) to simplify illustration ofapparatus 2. As shown inFIGS. 1 a and 1 b, thebed 4 is substantially flat and rectilinear having a cab end 4 a and a rear end 4 b, also referred to as a “water end 4 b,” When viewed from rear end 4 b,apparatus 2 also has aleft side 4 c, aright side 4 d, and alongitudinal axis 4 e, i.e. a center line, that passes through a point at the center of cab end 4 a and extends through a point at the center of rear end 4 b and is parallel withsides Apparatus 2 includes awatercraft support assembly 8 mounted tobed 4, aramp assembly 10 attached by a pivotal and locking means 12 a to supportassembly 8, and a winching means 14 for winching a small watercraft upramp 10 and ontosupport assembly 8. In turn,ramp 10 is optionally comprised of two or more ramp subassemblies, e.g. inFIGS. 1 a and 1 b, 10 a and 10 b, which are joined to each other bypivotal means 12 b. Note that while only two ramp subassemblies are illustrated in the figures, more than two may be used in alternated embodiments ofapparatus 2. Pivotal means 12 a and 12 b are conveniently equipped with a locking provision. -
Support assembly 8 is comprised of tworails 16, substantially equal in length, attached byadjustable means 18 to a plurality ofperpendicular cross ties 19 to form a - Each
ramp subassembly support assembly 8. That is, each comprises two rails, 16 a and 16 b (16, 16 a, and 16 b are collectively referred to herein as “therails 16”) respectively attached byadjustable means 18 to two or moreperpendicular cross ties 19 a and 19 b that correspond torails 16 a and 16 b. Likewise, 19, 19 a, and 19 b are collectively referred to herein as “the cross ties 19.” Thesubassemblies subassembly 10 a to supportassembly 8. Should more than two ramp subassemblies be employed, pivotal and locking means the same as, or similar to, 12 b may be installed between each of the ramp subassemblies. The distance betweenrails 16 a and 16 b, respectively, corresponds to the distance between therails 16 a and 16 b of thesupport assembly 8. The terminal ramp subassembly, i.e.,subassembly 10 b inFIGS. 1 a and 1 b, may optionally be fitted with aprotective bumper system 21 at its end that rest on theground 22 below thewater level 24 of body of water 26 (seeFIG. 1 b) into whichpersonal watercraft 20 is being launch, or out of which, it is being retrieved. -
Ramp assembly 10 may be pivoted and locked at pivot means 12 a with respect to the plane of the supportingassembly 8 to facilitate launching and retrieving. Likewise, the ramp subassemblies, such as 10 a and 10 b illustrated inFIG. 1 a andFIG. 1 b, may be pivoted and locked at the pivotal means 12 a so that they are also in a configuration to facilitate launching and retrieving. Pivoting and configuring the support and ramp assemblies are discussed below in description of the operation ofapparatus 2. - The winching means 14 (
FIGS. 1 a and 1 b) may by any means known in the art for launching and retrieving small watercraft to and from trailers or dock launches. For example, conveniently a hand cranked, gear facilitated winch system widely used in connection with watercraft trailers may be employed. Even more convenient, are the widely used electrically actuated winch systems that typically operate off a vehicle battery. Both systems typically use a cable, rope, strap, chain, etc., (herein after, “cable 25”), with one end attached to the watercraft and the other end wound around a spool rotated by a hand crank or electric motor to lower or pull the watercraft along the rails ofapparatus 2.FIGS. 1 a and 1 b depict winching means 14 as shown mounted to supportingframe 28, which in turn is mounted to supportassembly 8 at the end distal to whereramp 10 is attached, i.e. cab end 4 a. - As noted above,
cross ties support assembly 8 andramp subassemblies adjustable means 18. Consequently, the distance between the rails may be adjusted to best accommodate the hull of any specific small watercraft as shown inFIG. 3 that depicts a cross section of theapparatus 2 and cross section of a supported watercraft. - Any adjustable means of attachment taught in the art of small watercraft launching and retrieval apparatus may be employed. For example, the adjustable bracket depicted in
FIGS. 2 a and 2 b asbracket 18 a is a convenient means of attachment.FIG. 2 a is a perspective view ofbracket 18 a prior to installation, whileFIG. 2 b showsbracket 18 a connectingrail 16 to one ofcross tie 19. As illustrated inFIGS. 2 abracket 18 a is “L” shaped having around hole 29 in one leg of the “L” and an elongated, i.e.oval hole 30 in the other leg.Bracket 18 a is affixed to rail 16 of support assembly 8 (in a similar manner to rail 16 a and 16 b oframp subassemblies round hole 29 and affixed to a cross tie with a second fasten means 34, e.g., a screw or bolt, throughoval hole 30. Such a fastening means is further illustrated in the cross sectional view ofFIG. 3 . - Conveniently, fastening means 34 is quick adjusting so that it can be quickly adjusted to allow rail 16 (a or b) to move inward or outward to the extent allowed by
oval hole 30, and quickly adjusted to lock when one or both ofrails 16 a or 16 b are the desired distance apart as shown inFIG. 3 . This teaching also applies to the attachment of the rails of the ramp to theircorresponding brackets 18 a. For example, fasten means 34 might have a small handle to avoid the need for a screw driver, wrench, or similar tool. Further, fasten means 34 may have a “snap-over-center” lever type widely used in the mechanical arts whereinbracket 18 a is free to move in one position but is locked in place when the lever is lifted up and placed in another position. - Turning to the cross sectional view of
FIG. 3 ,cross ties 19 that support rails 16 of thesupport assembly 8 may be attached tobed 4 by any means of the art for attachment of an object to a truck bed. However, conveniently it can be attached with fastening means 36 running throughcross tie 19 and penetrating intobed 4. For example, fastening means 36 may be quick adjusting means similar to fastening means 34 b. Referring toFIGS. 1 a, 1 b, and 3, alternatively or supplementally, thesupport assembly 8 may be secured tobed 4 by a plurality oflinear connectors 38 such as chains, cables, ropes, straps, and the like each of which is attached at one end toapparatus 2 and the other end attached to an anchor bracket (or the like) 40 mounted onbed 4. Conveniently,linear connectors 38 are equipped with quick connect/release means as well as quick adjustment means. - Again referring to
FIG. 3 , therails 16 may be beveled to better match the profile ofhull 41 of the watercraft. Further, as shown inFIG. 3 , the top of the rails may be covered with material that will promote sliding of the watercraft'shull 41 over the rails. For example, waterproof material, e.g., waterproof carpet, may be stretched across the top of the rails to formrail cover 42 that not only facilitates sliding along the rails, but also protects thehull 41 of thewatercraft 20. Alternatively, the tops of the rails may be equipped with a system of cylindrical or ball rollers to enhance the movement ofhull 41. -
Apparatus 2 may be constructed of any materials used in the art for constructing boat and personal watercraft launching and retrieval means, such as metal, metal alloy, wood, polymers, fiberglass, composite materials or any combination thereof. Examples of metals include protected steel or steel alloy, e.g. stainless steel and aluminum. For example, hardware and connecting item might be metal while the rails might be treated wood or polymeric material. The choice of materials is governed by their cost in consideration of their durability in a harsh outdoor environment. - Watercraft launching and retrieving
operations using apparatus 2 are illustrated inFIGS. 4 a-4 c. Note that for clarity, only items relevant to the discussion or needed for orientation are labeled. The reader is directed to previous figures for additional details. Referring toFIG. 4 a, while being transported,watercraft 20 rests onrails 16 ofsupport assembly 8 that is, in turn, attached tobed 4 oftruck 6.Ramp sub-assemblies b comprising ramp 10 are folded upward, fastened together by ramp fastening means 44, e.g. a cable orstrap securing ramp 10 tobed 4, and oriented substantially perpendicular tobed 4 and locked in place using locking provision ofpivotal mans - Referring now to
FIG. 4 b in the first step of launchingwatercraft 20,truck 6 is backed as close as possible to the edge of the body ofwater 26 into whichwatercraft 20 is to be launched in keeping with safety considerations. Typically, the rear wheels oftruck 6 are backed to within one to six feet (0.3 to 2 meters) from the water's edge, i.e., proximal to the water's edge, depending on the slope at the edge of the body ofwater 26. - Note that while
FIGS. 4 a-4 c show only two ramp subassemblies, one or more additional such subassemblies are within the scope of the present invention. Further, a means of quickly attaching additional ramp subassemblies, e.g. 10 c, 10 d, etc., sequentially to the end oframp subassembly 10 b to increase the span oframp assembly 10 is also contemplated and within the scope of the present invention. For example, one or more ramp subassemblies could be added betweenramp subassemblies - Prior to launching, after unlocking
pivotal means ramp sub-assemblies FIG. 4 b, and locked at pivotal means 12 a into a linear unit, i.e., ramp 10 as shown inFIG. 4 c.Ramp 10 is pivoted downward about pivotal and locking means 12 until the end oframp 10 distal to pivotal and locking means 12 rest on theground 22 below thewater level 24 of body ofwater 26 as shown inFIG. 4 c. The watercraft is launched by pushing it along rails 16 ofsupport assembly 8, down the rails oframp 10, and into the body ofwater 26. It is convenient if the land at the water's edge slopes slightly downward with the back wheels of the truck being lower than the front wheels so thatwatercraft 20 will have a tendency to slide backward alongsupport assembly 8. Iframp 10 is oriented at steep angle with respect tobed 4, descent ofwatercraft 20 to the water may be controlled by attachingcable 25 to the watercraft's bow and usingwinch 14 to inhibit its downward motion in the same manner that a boat or watercraft is typically launched from a trailer. As shown inFIG. 4 c,watercraft 20 has descendedramp 10 and its stern is floating on the water.Cable 25 is then detached andwatercraft 20 may be mounted and enjoyed. - Retrieval is substantially the reverse of the procedure for launching. That is, the watercraft is maneuvered as close as possible to the point that
ramp 10 enters the body ofwater 26 with its bow starting upramp 10. While it is possible to manually push the watercraft upramp 10, it is more convenient to attachcable 25 to the bow and pull it up ontosupport assembly 8 withwinch 14 as is it typically done when loading a watercraft onto a trailer. Whenwatercraft 20 is fully on the support assembly, in the transporting position as shown inFIG. 4 a, the watercraft is preferably secured in position by ropes, chains, straps, elastic bands or any other means used in the art for securing items to a truck or trailer. Whenwatercraft 20 is properly positioned and secured for transport,ramp 10 is folded upward and secured into its transporting position as shown inFIG. 4 a.Winch 14 can be conveniently used to assist in folding upramp 10.
