PORTABLE BOAT RAMP BACKGROUND OF THE INVENTION The present invention constitutes an improvement on my prior US. Pat. No. 3,353,363, issued Nov. 21, 1967.
SUMMARY It is a primary object of the present invention to provide a portable boat ramp for use in beaching and launching small boats on sandy or rocky beaches without the need of dragging the boat across the beach and which provides a stable support for the boat while on the ramp.
Another object of the invention is to provide a portable boat ramp which differs from the boat ramp of my prior US. Pat. No. 3,353,363, in that the ramp does not have to be dismantled for storage or transportation, provides a more compact unit when stored, and can be readily secured immovably in an extended position for use.
Another object of the invention is to provide a boat ramp having adjustable bolsters for engaging hull sides of different configurations and which in turn are supported by a stabilizing member to prevent any lateral rocking movement of the boat while supported on the ramp.
Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a fragmentary top plan view showing'the boat ramp in an extended,-operative position;
FIG. 2 is an end elevational view thereof, partly in cross section, looking from the lower toward the upper end of FIG. 1;
FIG. 3 is .a side elevational view showing the boat ramp folded;
FIG. 4 is a fragmentary top plan view of the central portion of the extended boat ramp, with certain of the parts omitted for clarity;
FIG. 5 is a sectional view, taken substantially along a plane as indicated by the line 5-5 of FIG. 4;
FIG. 6 is an enlarged fragmentary sectional view, taken substantially along a plane as indicated by the line 6-6 of FIG. 1;
FIG. 7 is an enlarged cross-sectional view, taken substantially along a plane as indicated by the line 7-7 of FIG. 2, and
FIG. 8 is an enlarged fragmentary cross-sectional view, taken substantially along the line 8-8 of FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring more specifically to the drawing, the portable boat ramp in its entirety and comprising the invention is designated generally 10 and includes a keel rest, designated generally 11, comprising an elongated rigid bar 12 having corresponding upturned portions 13 adjacent each end thereof, as seen in FIGS. 3 and 6, and inwardly extending corresponding terminal portions 14 which are disposed above and spaced from the plane of the bar 12.
A keel engaging member 15 is secured on each terminal 14. Said members 15 are elongated, disposed crosswise of the bar 12, are rounded in a direction crosswise thereof and are each provided with an elongated grooved intermediate portion 16. The keel engaging grooves 16 of the two members 15 are disposed in alignment with one another, as seen in FIG. I. An upright post or brace 17 extends between the bar 12 and each terminal 14 and said'posts are spaced from the adjacent ends of the terminals, as seen in FIGS. 3 and 6. The bar 12 is preferably reinforced by a pair of transversely spaced sill members 18 which are secured to its underside and extend substantially from end to end thereof.
A flat rigid stabilizing bar 19 is disposed above the bar 12, and the shank of a headed bolt 20 extends downwardly through the bars 19 and 12, is disposed intermediate of the ends of said bars and carries a wingnut 21, beneath the bar 12 and between the sills 18, for securing the stabilizing bar 19 to the keel bar 12. The bar 12 is pressed downwardly to form four upwardly facing rounded depressions 22 which are equally spaced from one another and from the bolt 20; and the bar 19 is pressedto provide four rounded bosses 23 on its underside which are sized and located to fit into the depressions 22, as seen inFIG. 5. Thus, with the stabilizer bar 19 disposed in its operative position, crosswise of the keel bar 12, as seen in FIGS. 1 and 2, the nut 21 can be tightened for retaining the bosses 23 in the depressions 22 for securing the bar 19 immovably to the bar 12.
The bar 19, on either side of and adjacent the bolt 20, is provided with a pair of transversely spaced aligned and upstanding apertured lugs 24. A pair of rigid bolster bars 25 are disposed above and lengthwise of the ends of the stabilizer bar 19 and having transversely spaced, aligned and apertured lugs 26 extending downwardly from the inner ends thereof. As best seen in FIG. 7, the pairs of lugs 26 straddle the lugs 24 and pivot pins 27 extend through the aligned lugs 24 and 26 for pivotally mounting the bars 25 on the bar 19 for up and down swinging movement. Each pivot element 27 may carry a spacer sleeve 28 between the lugs 24 engaged thereby.
Each of the bars 25, near its opposite end, is provided on its underside with a pair of aligned apertured lugs 29 to receive a pin 30 which extends therethrough. The pin 30 extends through an eye 31 on one end of a rod 32 which has a threaded opposite end portion 33, as seen in FIG. 2. Spacing sleeves 34 are mounted on the pin 30 between the eye 31 and lugs 29, as seen in FIG. 8. The threaded portion 33 of each rod carries a wingnut 35 which is adjustable thereon to form a stop by engagement with the upper surface of the bar 19 when the rod 32 extends through a longitudinally elongated opening 35, one of which is provided adjacentv each end of the bar 19, for supporting the bolster bars 25 in upwardly inclinedoperative positions, as seen in FIG. 2. Substantially hemispherically pads or cushions 36 are secured to the uppersides of the outer ends of the bars 25. The keel engaging members 15 and'the pads 36 may be formed of rubber, plastic or other similar cushioning materials.
With the ramp 10 extended, as seen in FIGS. 1 and 2, the keel bar 11 is disposed on the beach perpendicular to the waters edge and with one end thereof adjacent the waters edge. An end of the keel'37 of a small boat 38, as seen in dotted lines in FIG. 2, is positioned in the groove 16 of the keel engaging member 15, which located adjacent the waters edge, as an end of the boat is lifted and pulled toward the ramp. The boat is then pushed or pulled up the ramp 10, toward the other keel engaging member 15, with the weight of the boat supported on said first mentioned keel engaging member 15. After the preponderance of the weight of the boat has advanced beyond the keel engaging member 15, engaged by the keel 37, the bow or leading end of the boat is manually supported until the boat has been advanced up the ramp to a desired extent. The bow portion of the boat is then lowered so that the keel 37 will engage the other keel engaging member I 15. Transversely aligned portions of the sides of the hull of the boat 38 will then assume positions resting on the pads 36. If necessary, the wingnuts 34 can be adjusted for raising or lowering thebolsters 25 so that most of the weight of the boat will be supported by said bolsters.
The sills 18 and the bar 12 will sink into the beach surface so that the ends of the stabilizing bar 19 will rest on the beach and the lower ends of the rods 32 will be embedded in the beach surface to retain the ramp immovable. By lifting the bow of the boat to disengage the keel from the upper member 15 and the hull from the pads 36, the keel can slide readily down the lower member 15 as the boat is pushed outwardly between the posts 17 to fit on the bar 12 between said posts, and the bolster bars 25 do not extend to the ends of the bar 19 and fit under the extremities of the terminals 14, as seen in FIG. 2. It will be apparent that in this folded position of the ramp, the bosses 23 will engage the depressions 22 so that when the nut 21 is tightened, the ramp will be secured in its folded position for storage or transportation.
Various modifications and changes are contemplated and may be resorted to without departing from the function or scope of the invention.
