1. Field of the Invention
The present invention relates generally to safety devices for marine vessels, and more particularly to a lightweight adjustable hand rail for offshore boats.
2. Description of the Related Art
Deck rails are commonly found on marine vessels such as cruise ships and ferries to prevent passengers from falling overboard and to provide hand rails for use in heavy seas. In contrast, smaller boats and yachts must typically rely on the raised side walls and small hand holds of the vessels' outer shell to keep passengers from falling overboard. In some instances, a single curved bar is affixed to the top of the gunwale to provide something for a user to hold onto during rough seas or while walking near the edge of the deck.
With specific regard to fishing boats and other sport fishing vessels, there is often no protective railing located at or near the back portion of the boat due to possible entanglements with the fishing gear.
Accordingly, it would be beneficial to provide a boat rail apparatus capable of providing a safe experience for passengers without becoming obtrusive or detrimental to the activities of those onboard. It is also an objective of the invention to provide a boat rail apparatus that is lightweight, simple to use, and which is economical to manufacture.
The present invention is directed to an adjustable rail apparatus for a vessel. One embodiment of the present invention can include a horizontal support member and a pair of vertical legs extending downward to an attachment unit for securing the apparatus to a vessel.
Another embodiment of the present invention can include the ability for both the Horizontal bar and the vertical legs to be telescopic in nature, thus allowing the apparatus to be mounted to a wide variety of different vessel configurations.
Yet another embodiment of the present invention can include a method for installing an adjustable rail apparatus in a vessel in accordance with the above noted embodiments.
Presently preferred embodiments are shown in the drawings. It should be appreciated, however, that the invention is not limited to the precise arrangements and instrumentalities shown.
a is an expanded view of adjustable railing apparatus according to an another embodiment of the present invention.
While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the description in conjunction with the drawings. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the inventive arrangements in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention.
Although described as for use on a boat or water going vessel, the inventive concepts disclosed herein can be equally applied to vehicles, buildings and structures of all types without deviating from the scope and spirit of the invention.
The horizontal support bar 11 acts as the top (hand rail) portion of the rail apparatus 10. Each of the adjustable legs 12 and 13 act to define the height of the rail apparatus 10 and to provide lateral support. To this end, legs 12 and 13 are positioned parallel to each other and are secured in a perpendicular relationship to the underside of the horizontal support bar 11 via rivets or other known attachment hardware.
In one preferred embodiment, each of the support bar 11, and adjustable legs 12 and 13 can have a circular cross section and can be constructed from a hardened yet lightweight material such as metal tubing or hardened plastic, for instance, each having extremely good tensile strength. Of course, other shapes and materials are also contemplated.
As further shown in
Although described above as utilizing a fixing aperture that includes screws, the invention is not so limited, as any number of known components for securely positioning telescoping legs can be utilized without deviating from the scope of the inventive concepts disclosed herein. Moreover, although shown with two vertical legs, this is for illustrative purposes only, as embodiments having any number of vertical legs (including a single leg, for example) can be utilized without deviating from the scope of the inventive concepts disclosed herein.
a illustrates another embodiment of an adjustable railing apparatus 10 that further includes a jack 20 for automatically adjusting the height of the railing apparatus. In one preferred embodiment, jack 20 can include a hydraulic jack positioned within each outer rod 12a and 13a capable of raising and lower sliding rods 12b and 13b, respectively, when activated by a control switch, such as button 21. Such a unit can be powered by a direct current DC battery (not shown) specific to the device or can run off of the vessels onboard power supply. To this end, the apparatus can be self contained or integrated into the power supply of the vessel.
Although described above as including a hydraulic jack, many other known components for automatically raising and lowering the legs can be utilized without deviating from the scope of the invention. For instance, jack 20 can include hydraulic, pneumatic, DC motor, chain drive and other known elements capable of performing the required task. As each of these elements and their workings are well known in the art, no further description will be provided.
The attachment unit 14 can act to secure the rail apparatus to the deck, side wall, or gunwale of a boat or other such structure. To this end, attachment unit 14 according to one embodiment, can preferably include a metal flange secured to the bottom end of each leg 12 and 13. Each flange can include one or more openings 14a through which a screw, bolt or other such anchoring mechanism can be utilized to securely fasten the apparatus.
As shown, attachment unit 30 can include a mounting plate 31 for securing the top of the attachment unit to the underside of an adjustable leg 12 or 13, and an elongated rod 33 having a diameter sufficient to be securely positioned within the rod holder 35 of a boat rail 1. Owing to the fact that conventional rod holders 35 are mounted at a diagonal angle with respect to the boat rail 1, the attachment unit 30 can further include a leveling unit 32 having a handle and spindle 32a for allowing a user to adjust the angle of the mounting plate, and hence the leg to which it is attached, in a vertical position (see arrow B).
Such a feature can allow the adjustable railing apparatus 10 to be removably attached to a boat without the need for screws or nails which can damage the surface of the vessel. Moreover, this feature allows the apparatus to be removed from the boat for safe keeping while not in use.
Such a feature can allow the adjustable railing apparatus 10 to be utilized by a variety of vessels, each having different lengths. Additionally, by including the ability to change the length of the support bar 40, it is noted that the space between each of the adjustable legs 12 and 13 is also adjusted in a corresponding manner. As such, when used in conjunction with the removable attachment unit 30, such a feature can allow the adjustable legs to be spaced to fit within the existing rod holders of a vessel, without the need for custom fabrication.
Although described above as utilizing particular materials and methods, other embodiments are also contemplated. For instance, one or more elements of the adjustable railing apparatus 10 can be secured together utilizing any number of known attachment means such as, for example, screws, glue, rivets, compression fittings and welds, among others. Moreover, although the above embodiments have been described as including separate individual elements, the inventive concepts disclosed herein are not so limiting. To this end, one of skill in the art will recognize that one or more individual elements such as the support bar 11, support bar 40, adjustable legs 12 and 13, and/or the attachment unit 14 and removable attachment unit 30, for example, may be formed together as one continuous element, either through manufacturing processes, such as welding, casting, or molding, or through the use of a singular piece of material milled or machined with the aforementioned components forming identifiable sections thereof.
The method can begin at step 705 in which a user can determine a preferred location for the adjustable railing to be placed.
Next, the method can proceed to step 710 where the user determines if rod holders are present in the desired location. If rod holders are not present, the method can proceed to step 715 in which a permanent attachment unit can be utilized and the apparatus can be secured to the vessel in step 720, before proceeding to step 745.
Alternatively, if rod holders are present, the method will proceed to step 725 where a removable attachment unit can be utilized. Next, in step 730, the length of the horizontal bar can be adjusted so that the distance between the vertical legs matches the separation of the rod holders.
In step 735, the removable attachment unit can be secured to the rod holder and in step 740, the angle of the vertical legs can be adjusted so they are at a 90 degree angle relative to the boat deck.
Next, the method can proceed to step 745 where the height of the horizontal bar can be adjusted by increasing or decreasing the length of the vertical legs.
Although described above as being for use on an existing vessel, one of skill in the art will recognize that the embodiments disclosed herein can be incorporated into the design and manufacture of a new vessel so as to comprise an integral part of the vessel housing and/or side rail(s).
Accordingly, by incorporating the inventive concepts disclosed herein, a user can ensure passengers onboard vessels of any size are protected from falling overboard during rough seas or sporting activities. Moreover, users can easily lower the adjustable railing apparatus when easy access to the water is desired (such as while swimming, fishing or diving, for example) and then raise the railing when underway. Finally, by incorporating lightweight materials in the construction of the device, it is possible to install the adjustable railing apparatus to vessels of all sizes without creating excessive drag or excessive weight which can affect the ballast and handling of the vessel.
