Non-applicable.


FIELD OF THE INVENTION

The presently disclosed subject matter is directed to an adjustable step.


BACKGROUND OF THE INVENTION

Recreational boating has earned a well-deserved spot of the list of favorite pastimes of countless people. The ability to get outside and enjoy warm weather, sunshine and water make all kinds of boating truly enjoyable. One skill that must be mastered by all boat users is climbing in and out of the boat, typically from a dock. While easy for many, the vast height difference between the dock surface and the boat, depending on water levels, make transfers difficult.


While intermediate steps would certainly assist, they often prohibit the boat from approaching the dock. Additionally, as water levels vary, permanently installed steps would be at the wrong position as well. Accordingly, there exists a need for a means by transfer in and out of a boat from a dock can be made easier for all in a manner which addresses the above-mentioned concerns. The development of the adjustable step fulfills this need.


SUMMARY OF THE INVENTION

The principles of the present invention provide for an adjustable removable step which comprises a step section which has a top portion. The top portion is covered with a non-slip surface that serves as a stepping point for a person's foot. The adjustable removable step also comprises a clamp section which forms a “C-shaped” structure around a clamping area. The step section and the clamp section are manufactured from a single continuous piece of material. The clamping area is surrounded by the clamp section on three sides of the clamp section. The adjustable removable step also comprises a threaded fastener which secures the clamp section to a support structure. The threaded fastener includes a first washer and a second washer. The adjustable removable step also comprises a threaded hole which is disposed adjacent to the clamp section to receive the threaded fastener.


The non-slip surface is a safety feature of the adjustable removable step that may prevent slips and falls. The step section may be positioned in a perpendicular manner to the support structure and may be secured in place via the clamp section and the threaded fastener. The non-slip surface may be a surface selected from the group consisting of an adhesive coating, one or more directly applied materials, a plurality of embossed grooves, or a plurality of machined grooves. The step section may be five-and-three-quarter inches long. The single continuous piece of material may be a metal selected from the group consisting of galvanized steel, stainless steel, or aluminum alloy or may be aluminum alloy 6061-T6 to provide strength and ease of heat-treatment.


The washers may distribute pressure of the threaded fastener evenly over the support structure, so the support structure isn't damaged. The washers may ensure that the threaded fastener may be pressed against a smooth surface of the washers which reduces the chance that the washers gradually loosen because they are in contact with an uneven surface. The threaded fastener may be a fastener selected from the group consisting of a bolt, a screw, or a cylindrical socket head cap screw while the support structure may be a standard two-inch tube accepted by the clamping area. The support structure may also be a standard two-and-a-half inch tube accepted by the clamping area. The clamp section may be positioned at a fifteen degree angle to a horizontal axis. The adjustable removable step may be slid up and down the support structure along an adjustable removable step travel path for a final resting position at an infinite number of locations. The three sides of the clamp section may surround and receive the support structure within the clamp section. The threaded fastener may be loosened but not removed to allow for repositioning of the step section along the support structure. The threaded fastener may be tightened against the clamp section to secure the adjustable removable step once the step section is repositioned. The second washer may be made of neoprene to enable vertical adjustment of the step section along the support structure without having to remove the threaded fastener. The adjustable removable step may hold up to three hundred and fifty pounds. The adjustable removable step may be ten inches long and three-and-a-half inches wide.

However, the invention is not limited to the described embodiment, and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one (1) particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims.


The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one (1) of the referenced items.


1. DETAILED DESCRIPTION OF THE FIGURES

Referring now to FIG. 1, a top view of the adjustable removable step 10, according to the preferred embodiment of the present invention is disclosed. The adjustable removable step 10 (herein also described as the “step”) 10, is an attachable and adjustable step, particularly suited for removable attachment to a boat dock or similar vertical structures. The step 10 includes a step section 15 and a clamp section 20. Both the step section 15 and the clamp section 20 are envisioned to manufactured from one (1) continuous piece of metal such as aluminum alloy 6061-T6. However, the step 10 may be made from other equivalent metal such as galvanized steel, stainless steel, other grades of aluminum, or the like, and as such, the materials of construction are not envisioned to be a limiting factor of the present invention.


The top portion of the step section 15 is covered with a non-slip surface 25 such as, but not limited to: an adhesive coating, directly applied materials, embossing or machined grooves directly in the step section 15 or the like. As the area occupied by the non-slip surface 25 serves as a stepping point for a user's foot in a water-based environment and likely to be slippery, the non-slip surface 25 is a safety feature of the step 10 by preventing slips and falls.


The clamp section 20 form a “C”-like structure around a clamping area 30. The clamping area 30 will be described in greater detail herein below. Securement of the clamp section 20 is provided by a first washer 35, a second washer 37, and a threaded fastener 40. The threaded fastener 40 is envisioned to be a cylindrical socket head cap screw (as shown). However, other types of fasteners such as bolts, screws, and the like may also be used with equal success. As such, the exact type of threaded fastener 40 is not intended to be a limiting factor of the present invention. The step 10 is envisioned to be used upon and supported by standard two-inch (2 in.) or two-and-a-half (2½ in.) tube commonly used to make boat docks and would subsequently be accepted by the clamping area 30. However, those skilled in the art will realize that all dimensions of the step 10 can be readily modified to allow the step 10 to easily be mounted on a wide variety of suitable structures. All dimensions are scalable, both proportionally and individually, to suit the need at hand. Approximate nominal dimensions of a typical step 10 are envisioned to be ten inches (10 in.) long and three-and-a-half inches (3½ in.) wide. The step section 15 would be approximately five-and-three-quarter inches (5¾ in.).


Referring next to FIG. 2, a side view of the step 10, according to the preferred embodiment of the present invention is depicted. In this figure, the first washer 35, second washer 37, and the threaded fastener 40 (as shown in FIG. 1) are not shown for purposes of clarity. The non-slip surface 25 is shown atop the step section 15. The clamping area 30 is surrounded by the clamp section 20 on three (3) sides. A threaded hole 45 is provided in the distal surface of the clamp section 20 for acceptance of the threaded fastener 40 as aforementioned described. The clamp section 20 is positioned at an angle “a” 50 envisioned to be approximately fifteen degrees (15°).


Referring now to FIG. 3, a side view of the step 10, shown in a state of being installed, according to the preferred embodiment of the present invention is shown. During installation of the step 10 upon a support structure 55. The clamp section 20 is placed at a 90-degree (90°) angle “b” 60, with the three (3) sides of the clamp section 20 is mechanical communication with the 90-degree (90°) angle “b” 60. It is noted that the threaded hole 45 is visible and the first washer 35 and the threaded fastener 40 (both of which are shown in FIG. 1) are removed. This placement orientation places the non-slip surface 25 at a fifteen degree (15°) upward angle During such a configuration, the step 10 may be slid up and down the support structure 55 along a step travel path “s” 65 for a final resting position at any one of an infinite number of locations.


Referring next to FIG. 4, a side view of the step 10, shown in an installed state, according to the preferred embodiment of the present invention is disclosed. The step section 15 of the step 10 is angled downward along a fifteen degree (15°) with respect to the clamp section 20. The step 10 is then secured to the support structure 55 with the use of the oversize washer 35 and the threaded fastener 40 that is placed into the threaded hole 45 (as shown in FIG. 2). At this point in time, the step 10 is ready for utilization.


Referring to FIG. 5, a perspective view of the step 10, shown in an installed state, according to the preferred embodiment of the present invention is depicted. This view more clearly shows the position of the step 10 upon the support structure 55. The step section 15 with its non-slip surface 25 is positioned in a perpendicular manner to the support structure 55 and is secured in place via the clamp section 20 and the restraining first washer 35, second washer 37 and threaded fastener 40. It is envisioned that the first washer 35, second washer 37, and threaded fastener 40 may be loosened but not removed, to allow for repositioning of the step section 15 along the support structure 55 in general motion along the step travel path “s” 65 (as shown in FIG. 3). Once repositioned, the threaded fastener 40 may be tightened against the first washer 35, second washer 37, and the clamp section 20 to secure the step 10. Preferably, however, the threaded fastener 40 secures the first washer 35 and second washer 37 permanently to the clamp section 20. The material of the second washer 37, envisioned to be neoprene or other similar material, enables vertical adjustment of the step section 15 along the support structure 55 without having to remove the threaded fastener 40.


While specifically envisioned for use on boat docks made of tubular steel, the step 10 may be used on any similar structure in which climbing access is required. The repositionable nature of the step 10, makes it ideal for use in locations where water levels change and the need for steps in varying positions are important. The materials and corresponding design of the step 10 are envisioned to hold up to three hundred and fifty pounds (350 lbs.).
