Abstract
Disclosed is a device that engages and stabilizes a personal watercraft for boarding or exiting. The device simultaneously engages upper surface elements of the watercraft whilst also providing firm land/pier engaged support to the user. A user's weight is able to bear against the inherent buoyancy of the watercraft through a structure rotated downwardly to the watercraft; the rotated structure is hinged and fixed to the land/pier. During entry, the upwardly urging buoyancy of the watercraft stabilizes the watercraft against the downwardly rotated structure while a user steps from the land/pier to the watercraft and fully transfers weight to the watercraft. Exit is the reverse. A method of associated use is also disclosed.

[0030] The hinging arm (2) can be configured from either round, square, rectangular, octagonal, hexagonal, or triangular tube of various types of metal, alloys, plastics, wood, composites, fiberglass, or paper of various sizes and dimensions. The hinging arm (2) connects the main rectangular structure (1) to the hinge plate (3). The round or square arm (2) tube, inserts into the main rectangular structure (1) off to one side preferably in-line with the lower bottom bar between the right and left sides of the rectangle, this optional feature allows adjustment horizontally for differing widths of watercraft in its full use positioning and for stowing purposes. In this embodiment it is secured by a small safety/adjusting pin (18).
[0031] The hinge plate (3) can be built from various types of metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions. The hinge plate (3) connects to the hinging arm (2) which connects to the main rectangular structure (1). The hinge plate (3) is mounted by, for example, bolts (10, 11, 12, 13, or 16) to a solid structure like a dock (17) or boat platform, or to other bracket variations (like auxiliary mounting plate (15)) that could be made in order to accommodate the hinge plates (3) vertical mounting position within reasonable height location of the dock (17) or platform (17) to the ordinary/expected water level (20).
[0032] The optional straight legs (4) can be built from either round, square, rectangular, octagonal, hexagonal, or triangular tube of various types of metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions. The optional version has the ability to adjust the straight legs (lengthen or shorten) vertically. This can be done by means of either a small safety/adjusting pin (18) or internal spring style push-in turn, push or pull to the new position, then the button pops back out on the main rectangular structure (1) to secure. The no adjustment option has the legs built as part of main rectangular structure (1), like the hinge arm (2), as a solid structure, with no provision for adjustments.
[0033] The connecting pin (5) can be built of various types of metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions. The connecting pin (5) attaches the main rectangular structure (1) with its attached hinging arm (2) to the hinge plate (3). The cotter pin (6) can be made of steel, zinc plated steel, stainless steel or galvanized steel. The cotter pin (6) is simply used, in this embodiment, to secure connecting pin (5).
[0034] The offset style legs (7) are inserted into the main rectangular frame (1), and are fully adjustable in order to accommodate a wider or narrower contact area on upper surface shapes of the underlying watercraft. The offset leg (7) can be built from either round, square, rectangular, octagonal, hexagonal, or triangular tube of various types of metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions.
[0035] The feet (8) can be made out of different types of foam products, cloths, soft plastics, rubber, and other weather resistant materials. The feet fit over the end of the adjustable straight legs (4) or offset legs (7) that make non-sliding contact to the surface of the watercraft.
[0036] The optional knee/shin pad (9) can be made out of different types of foam products, cloths, soft plastics, rubber, and other weather resistant materials. The cross-sectional views (
[0037] The various hardware, 10, 11, 12, 13, 16 including bolts, nuts, washers, can be made of galvanized steel, stainless steel or zinc plated steel, in various sizes, strengths and lengths. These are variously used to attach the hinge plate (3) to a solid structure (17). The gussets 14 (two or more possibly used) are optional, depending on material used to build and stiffen the main rectangular structure (1) where the hinging arm (2) is inserted into the main rectangular structure's horizontal to vertical joint area.
[0038] The auxiliary mounting plate (15) is optional and, if needed, can be added to hinge plate (3) by welding, bolting, gluing or fusing for purpose of needing an alternative or supplemental structural element in order to secure the hinge plate (3) to the solid structure (17). The auxiliary mounting plate can be made from metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions.
[0039] The solid structure (17) like a fixed post, a dock (floating or fixed), or a large boat's rear platform (stern) is necessary to mount the hinge plate (3) to along with auxiliary mounting plate (5) (if needed). The safety/adjusting pin (18), optional if needed, one to three used, can be made from metal, alloys, plastics, wood, hemp, composites, fiberglass, or paper of various sizes and dimensions. The safety/adjusting pin (18) is used for adjusting the main rectangular frame (1) connection to the hinging arm (2) with a safety chain attached to main rectangular structure (1) just in case the user drops the pin it will not be lost in the water rendering the unit useless until another pin is acquired to replace it. The same style pin can be used to adjust the straight legs (4) or the offset legs (7) in or out on the main rectangular structure (1).
[0040]
[0041] As for mounting the invention to larger boats, for example a yacht that could accompany smaller watercraft like a kayak or paddleboard that would be launched off the stern of the vessel, the auxiliary mounting would have to be custom built for the application and would have different dimensions, mounting capabilities and designs to make the hinge-plate positioning adequate to directly attach the device to. The same principal would apply to an upright fixed post or any other unusual or uncustomary docks.
Method of Use for the Invention
[0042] The user will use one hand to line up the watercraft in the water (20) along with rotating the embodiment in the other hand towards the water making the feet of the embodiment come in contact with the watercraft ensuring that it is as close as possible to the front side of the weight and balance pocket of the watercraft and centered under the rectangular frame (1). The user will then apply pressure pushing downward using their own weight against the top of the rectangular frame with two hands as it hinges over (leveraged) making pressured contact with the watercraft ensuring that the embodiment is close to 80-90 degrees (shy of a right angle) compared to the hinge point (horizontally) or the deck (vertically), but, not too much beyond, otherwise the legs will need to be adjusted either in or out, then rechecked. Once the adjustments are satisfactory, the user continues to apply pressure as they push the watercraft into the water and continue to transfer their body weight towards the embodiment and watercraft pushing it even further into the water, thus stabilizing it. The user continues to hold downward pressure with two hands on the top horizontal bar and is stabilized as they start to step onto the watercraft with one foot, then the other, transferring all their weight onto the watercraft in a standing position. The user continues to hold on to the top horizontal bar with some downward pressure. The bottom bar between the rectangular frames right and left sides located in-line with the hinging arm (which is attached to the dock) is where the user puts their knees or shins against (a padded bar) as the user begins to kneel down to assist in (while holding onto the top bar with both hands) assuming a sit down or kneeling position, or continue standing if that is the desirable position for the watercraft being used. The process is reversed for exiting the watercraft: if sitting, line oneself up with the embodiment frame (1), rotate it over to make contact with the watercraft (because the user is already in the watercraft it is already weighted down, the embodiment is easily set to position against the watercraft), grab the top bar with both hands and pull yourself upward using the padded lower bar with your knees or shins for leverage and stability to a standing position. When standing (and continuing to have both hands on the top horizontal bar), take one foot out and step onto the dock then the other transferring weight away from the embodiment. Continue to rotate the embodiment away from the water 90 degrees to a stow position and then secure your watercraft.
[0043] NOTE: When adjusting the embodiment to accommodate the watercraft, it is important to get as close to the center of gravity as possible, within the weight and balance pocket of the watercraft. The higher the watercraft is above the water the higher the contact angle will be (up to 45 degrees with no pushing or weight applied), also the weight of the user needs to be taken into consideration so that the rotation of the main rectangular structure does not surpass 90 degrees, if at all, to the mounting plate or in other words the lower horizontal bar is close to parallel to the water, but not much over, otherwise the embodiments legs will need to be adjusted. The same principal applies for not enough weight or improper adjustment where watercraft is not pushed close enough to the 80 to 90 degree mark, simply re-adjust the embodiment. The lower the watercraft is to the waterline the further the legs must be adjusted outward and the less the contact angle will be (particularly for a paddleboard or the bottom (floor) of a canoe), care needs to be taken making large steps downward as to not force the watercraft out of the pocket by opposing force when making contact, step as straight down as possible. The same principal applies for exiting.
