This is a continuation or application Ser. No. 08/164,349 filed Dec. 9, 1993 now abandoned which is a continuation of Ser. No. 08/006,479 filed on Jan. 21, 1993 now abandoned.
The present invention relates to boat trailers in general, and in particular to a trailer for supporting a personal watercraft or the like pleasure boat.
Although the advent in the pleasure boat field of personal ski boats and the like brought a plethora of streamlined and stylish ski boats to satisfy those of all persuasions as to boat styles and sizes, the trailers for supporting and transporting this new personal phenomenon of the boating industry remained of the work horse type. Thus the contemporary trailers comprised a generally box-type frame with cross members supported by conventional brackets, either bunk or roller units, and with one or more vertically upright posts on the tongue or interior frame members for supporting winches. Although these ski boat trailers were functional, they were certainly susceptible to structural and design improvements to bring them at least even with the innovations of that which they carried, the personal watercraft.
The improved trailer includes a frame unit having portions extended parallel each other, a wheel and axle unit for supporting the frame unit, a cross member secured to and extended between the frame rear portions, a pair of V-shaped bracket units secured in longitudinally aligned, spaced relation on each frame portion, and a pair of transversely spaced elongated bunks for supporting a personal watercraft mounted in parallel relation on the bracket units. The improved trailer is enhanced by the provision of an elongated, arcuately curved element secured at one end to each frame portion, and having a bow stop and winch unit mounted on the other free end of the element.
It is an object of this invention to provide an improved trailer for supporting either a single or a pair of personal watercraft.
Yet another object of the invention is to provide a trailer for supporting either a single or pair of personal watercraft wherein the need for an intermediate cross member or intermediate longitudinal frame members is obviated.
Still another object for this invention is to provide a single or twin personal watercraft boat trailer having a simple, structurally sound design which is economical and effective in use.
These and other attributes of the invention will become more clear upon making a thorough review and study of the following description of a preferred embodiment, particularly when reviewed in conjunction with the drawings, wherein:
FIG. 1 is a perspective view of the boat trailer of this invention;
FIG. 2 is an enlarged plan view of the trailer of FIG. 1, with a pair of personal watercraft shown in dashed lines;

FIG. 5 is a side elevational view taken along the line 5--5 in FIG. 4;
FIG. 6 is an end elevational view taken along the line 6--6 in FIG. 2;
FIG. 7 is a fragmentary plan view taken along the line 7--7 in FIG. 3;
FIG. 8 is an enlarged detail view of FIG. 3;
FIG. 9 is a vertical sectional view taken along the line 9--9 in FIG. 8; and
FIG. 10 is an enlarged detail of FIG. 9.
Referring now to the drawings, the boat trailer of this invention is illustrated generally at (10) and comprises a frame unit (11) (FIGS. 1 and 2) including a pair of laterally spaced frame portions (12), (13) having rear ends (14), (15); a wheel and axle unit (17) for supporting the frame unit (11); a cross member (18) secured to and extended between the frame portion rear ends (14), (16); a pair of V-shaped bracket units (19), (21) and (19'), (21') secured respectively to frame portions (12), (13); and a pair of bunk elements (22), (23) secured in parallel relationship to each of the bracket unit pairs (19), (21) and (19'), (21') for supporting a pair of personal watercrafts (24), (26) shown in phantom in FIG. 2. Optional winch post assemblies (27), (28) (FIGS. 1 and 3) are mounted respectively, forwardly on the frame portions (12), (13) for operator winch control of the positioning of each watercraft (24), (26).
More particularly, the frame unit (11) has an A-shape with forward elements (29), (31) (FIG. 2) of the frame portions (12), (13), respectively, converging to form a tongue unit (32) with a standard hitch (33) for connection to a prime mover (not shown) for transporting the trailer (10). An elongated walkboard (34) is provided, extended along the centerline of the trailer (10) between a mounting connection (36) to the front of the frame unit (11) and a mounting connection (37) on the cross member (18) at the rear of the frame unit (11). The frame portions (12), (13) are parallel each other and the walkboard (34), all three components disposed longitudinally of the trailer (10). The cross member (18) ties together the rear ends of the frame portions (12), (13) (FIG. 2), extended transversely of the frame unit (11) with outer ends (38), (39) for mounting reflective or lighted tail lights (not shown) and/or license plates (41) (FIG. 1). A jack stand (40) (FIG. 1) is provided at the tongue unit (32) for supporting the frame unit (11) as mounted on the wheel and axle unit (17) in a level condition.
The wheel and axle unit (17) is conventional, comprising a transverse brace (42) (FIGS. 2 and 7) secured at (43) beneath each frame portion (12), (13) for support thereof at a location intermediate the length of the portions (12), (13) as best illustrated in FIGS. 2 and 3), and including a torsion axle device (44) (FIG. 7) secured at each outer end (46) of the brace (42) for flexibly supporting a wheel (47). A fender unit (48) for covering each wheel (47) is mounted by a bracket (49) to each brace outer end (46).
To support the hunk elements (22), (23), each bracket unit (19), (21) and (19'), (21') is identical, and comprises a pair of wing members (51), (52) (FIG. 6), each wing member having an inner end (53) secured to a respective side of the frame portion (12) or (13), with the outer end (54) extended laterally outward and upwardly. A plurality of bolt holes (56) are formed in longitudinally spaced relation in each wing member outer end (54) for bunk adjustment purposes described hereinafter.
Thus, each frame portion (12), (13) carries a pair of identical bracket units (19), (21) and (19'), (21'), respectively, in longitudinally spaced and aligned relation. In this manner, laterally spaced pairs of bunk elements (22), (23) (FIGS. 2 and 6) are mounted in parallel relation in a nested manner on the outer ends (54) of the wing members (51), (52). Each bunk element (22), (23) has a mounting plate (58) (FIG. 6) secured thereto at each end for adjustable connection via the holes (56) to the wing member outer ends (54); and with the connections (59) pivotal to enable the bunk elements (22), (23) to pivot about a horizontal axis longitudinally of the trailer (10) to adjustably receive the hull (61) of the watercraft (24), (26) supported thereon.
The optional winch post assemblies (27), (28) are identical, each comprising an elongated element (62) (FIGS. 3 and 8), a winch device (63) (FIG. 5) and a bow stop (64). The element (62) has one end (66) substantially straight for mounting longitudinally with and on top of a forward part of each frame portion (12), (13), as by a pair of U-bolt fasteners (67), (68), and with an integral free end (69) curved upwardly in an arcuate manner as best illustrated in FIG. 3. A rubberized or like bumper (70) is affixed to the rear portion (75) of the end (66) for safety purposes.
By referring to FIG. 2, it will be noted that the element (62) is disposed in a vertical plane aligned longitudinally with at least a part of each frame portion (12), (13) and that each element (62) is also disposed laterally, centrally of each pair of bunk elements (22), (23), thus placing each winch device (63) mounted at the upper end (71) of each free end (69) at a location in front and centrally of the transportation position for each personal watercraft (24), (26). In this manner, with the winch strap (72) (FIG. 5) secured at (73) to a watercraft (24), (26), upon winching the watercraft forwardly upon its respective pair of bunk elements (22), (23), the bow (74) may be brought into engagement with the bow stop (64) secured to the free end (69) slightly rearwardly of the winch device (63).
By this arrangement, an improved trailer is provided for supporting either a single or a pair of personal watercraft. Each on a pair of bunk elements (22), (23) arranged in a nesting condition by a pair of V-shaped bracket units (19), (21) or (19'), (21'). A pair of watercraft, when mounted on the trailer (10) would be placed in a parallel, side-by-side condition symmetrically arranged for balance on either side of the trailer longitudinal centerline due to the symmetrical arrangement of the bracket units (19), (21) and (19'), (21'), and their bunk elements (22), (23) in relation to the trailer frame unit (11).
