Title: Amusement dunk tank step assembly

Description:
BACKGROUND OF INVENTION 
     1. Technical Field 
     This invention relates to the field of amusement systems, and more specifically, to an amusement dunk tank step assembly. 
     2. Background Art 
     An amusement system which has long been popular at fairs, amusement parks and other entertainment activities is a dunk tank system. Amusement dunk tank systems may be found in assorted types and styles. Some conventional dunk tank systems are non-portable in the sense that they may not be moved, or at least not moved very easily. Generally, these conventional, non-portable dunk tank systems are arduously and permanently assembled onsite so that they remain stationary and are not easily disassembled and transported from location to location. 
     Other conventional dunk tank systems are transportable in the sense that they may be moved, such as tub styled dunk tank systems for example. Generally, these conventional transportable dunk tank systems may be pre-fabricated and self-contained dunk tank systems with components/equipment permanently attached or molded to their frameworks so as to require little or no onsite assembly. Such dunk tank systems are typically permanently mounted upon a wheel-based, mobile trailer. Alternatively, conventional transportable dunk tank systems may have frameworks and components/equipment that are easily assembled onsite, easily disassembled, and easily transported from location to location. For example, square styled dunk tank systems are available that include a series of frames that fit together to form a square shaped framework into which a vinyl bag insert adapted to contain water is secured. 
     In operation, after conventional dunk tank systems are located in a suitable location, a patron sits upon a load-supporting platform or seat while other people throw balls or other objects at one or more targets, attempting to activate a release mechanism. When the target is struck, the platform is caused to drop the patron into water or some other fall-breaking fluid or material. 
     However, these conventional dunk tank systems have certain drawbacks that have long existed and have not been effectively overcome. In conventional dunk tank systems, once a patron is dropped into the tank, the patron must negotiate his own way out of the dunk tank to reseat himself upon the platform in preparation for being dunked again or exiting the tank all together. That is, there is no effective dunk tank mechanism that facilitates the patron&#39;s exiting of the dunk tank. Rather, the patron must push and/or pull himself up out of the dunk tank. Thus, conventional dunk tank systems do not provide a suitable mechanism that allows a patron dropped into a dunk tank to easily exit the dunk tank and reseat himself upon a platform. 
     DISCLOSURE OF INVENTION 
     Therefore, what is needed is an amusement dunk tank mechanism that allows a patron dropped into a tank to easily exit the tank and reseat himself upon a platform, thereby overcoming the aforementioned disadvantages of conventional amusement dunk tank systems. The invention solves these problems through an amusement dunk tank step assembly that is configured to provide certain advantages including: positioning and allowing patrons dropped into dunk tanks to easily exit therefrom and reseat themselves upon platforms; removably mounting to dunk tanks easily for set-up in a plurality of locations; and/or retrofitting virtually any existing dunk tank and/or fitting virtually any newly manufactured dunk tank.

     DETAILED DESCRIPTION OF INVENTION 
     The invention provides an amusement dunk tank step assembly that is configured to provide certain advantages including: positioning and allowing patrons dropped into dunk tanks to easily exit therefrom and reseat themselves upon platforms; removably mounting to dunk tanks easily for set-up in a plurality of locations; and/or retrofitting virtually any existing dunk tank and/or fitting virtually any newly manufactured dunk tank. Generally, an amusement dunk tank step assembly of the present invention includes a mounting member configured to removably mount on an upper portion of a dunk tank. An upper portion of a rail member is coupled to the mounting member and is configured to be adjacent to an internal portion of the dunk tank when the step assembly is in an operative position. A step member is coupled to a lower portion of the rail member and is configured to be adjacent to the internal portion of the dunk tank when the step assembly is in an operative position. 
     Particularly, the present invention may be readily adapted to a variety of embodiments of an amusement dunk tank step assembly. With reference to FIG. 1, amusement dunk tank step assembly  2  is one example of a dunk tank step assembly of the present invention. It will be understood by one of ordinary skill in the art that the invention is not limited to the specific structures illustrated in the drawings. Generally, step assembly  2  includes mounting member  9 , rail member  18 , step member  22 , handle member  24 , and retaining member  26 . 
     Referring to FIG.  1  and describing amusement dunk tank step assembly  2  in greater detail, mounting member  9  is configured to removably mount on an upper portion of a dunk tank. Mounting members that removably mount on an upper portion of a dunk tank in any fashion are within the scope of the present invention. For the exemplary purposes of this disclosure, though, mounting member  9  includes insertion member  12  configured to removably insert into an upper portion of the dunk tank when step assembly  2  is in an operative position. Insertion members may have any structure that is adapted to removably mount into, around, over, etc. another structure. 
     Mounting member  9  also includes extension member  15 . Extension member  15  may be substantially perpendicular to rail member  18  and insertion member  12 . Thus, extension member  15  may comprise a first portion coupled to the upper portion of rail member  18  and a second portion that may be coupled to insertion member  12  or to insertion member  12  and handle member  24 , depending upon their configurations, such that insertion member  12 , rail member  18 , and/or handle member  24  are substantially parallel with one another. However, for the exemplary purposes of this disclosure, the second portion of extension member  15  is coupled to a to retaining member  26  that is configured to couple insertion member  12  and handle member  24 . Retaining member  26  may comprise a sleeve member into which is coupled handle member  24  and insertion member  12 , thereby retaining them at appropriate positions relative to the particular mounting or gripping applications for example. 
     Insertion members, extension members, and retaining members may have various lengths and have various outside diameters depending upon the configuration of an amusement dunk tank and the particular mounting application for example. Furthermore, insertion members, extension members, and retaining members may comprise assorted shapes and structures, although insertion member  12  and extension member  15  may comprise approximately 1″ outside diameter square tubing for the exemplary purposes of this disclosure, while retaining member  26  may comprise approximately 1¼″ outside diameter square tubing for the exemplary purposes of this disclosure. 
     Rail member  18  is configured to be adjacent to an internal portion of the dunk tank when step assembly  2  is in an operative position. An upper portion of rail member  18  is coupled to a first portion of extension member  15  and rail member  18  may be perpendicular to extension member  15 . Rail members may have various lengths depending upon the height of the dunk tank for example, and may also have various outside diameters depending upon the particular application. Furthermore, rail members may comprise assorted shapes and structures. As depicted in FIG.  1  and for the exemplary purposes of this disclosure, though, rail member  12  may comprise approximately 1″ outside diameter square tubing. 
     Step member  22  is also configured to be adjacent to the internal portion of the dunk tank when step assembly  2  is in an operative position and is coupled to a lower portion of rail member  18 . Step members may have various sizes, etc. depending upon the configuration of the dunk tank and the particular application for example. Furthermore, any step configuration or structure is within the scope of the present invention. Thus, step members may be assorted configurations (e.g. rectilinear, curvilinear, etc.) depending upon the configuration of the dunk tank for example, and may be comprised of a variety of structures as well. However, as depicted in FIG.  1  and for the exemplary purposes of this disclosure, step member  22  may have a right-angled triangular shape configuration and comprise an L-shaped bracket coupled to a step plate, the bracket and the plate having approximately a ¼″ thickness. 
     Handle member  24  is configured to facilitate exiting and entering a dunk tank. Handle member  24  is coupled to the mounting member  9 , and more specifically, it is coupled to insertion member  12  and extends outwardly therefrom in a substantially parallel fashion. Handle member  24  and insertion member  12  may be integrally joined to one another. Handle members may have various lengths and have various outside diameters depending upon the particular application. Furthermore, handle members may comprise assorted shapes and structures that allow gripping. As depicted in FIG.  1  and for the exemplary purposes of this disclosure, handle member  24  may comprise approximately 1″ outside diameter square tubing. 
     Turning to FIGS. 1-4, alternate amusement dunk tank step assembly embodiments of the present invention are respectively illustrated that are similar to step assembly  2  embodiment previously described. Therefore, only differences between step assembly embodiments will be highlighted. The following step assembly embodiments and those previously described may be combined in any manner within the scope of the present invention. 
     A mounting member configured to removably mount on an upper portion of a dunk tank in any fashion is within the scope of the present invention. In some step assembly embodiments of the present invention, any mounting member and rail member within the scope of the present invention in combination may form a hook-shape, cane-shape, or other similar shape for removably surrounding/encapsulating the upper portion of an amusement dunk tank when the step assembly is removably mounted in a plurality of operative locations to accommodate dunk tank component/equipment configurations, etc. For example, in FIG. 2, mounting member  10  may include extension member  16  having a first portion coupled to the upper portion of rail member  18  and a second portion configured to be adjacent to a top portion and an external portion of the upper portion of a dunk tank when step assembly  4  is in an operative position so that rail member  18  and extension member  16  encapsulate the upper portion of the dunk tank. 
     In association with still other step assembly embodiments of the present invention, a step member may include a plurality of step members coupled and positioned at operative locations along a length of any rail member within the scope of the present invention to account for varying heights of dunk tanks and patrons, etc. For example, in FIG. 2, two step members are coupled and positioned at operative locations along a length of rail member  18 , although any number of step members may be utilized. 
     In association with yet other step assembly embodiments of the present invention, any rail member within the scope of the present invention may be extendable along its length. That is, a particular rail member may be configured to telescope, extend, adjust, or the like in any manner or by any mechanism, while still being able to couple to a mounting member and a step member within the scope of the present invention. For example, turning to FIG. 3, step assembly  6  similar to step assembly  2  in FIG. 1 includes a rail member that comprises sleeve portion  20  that slidably removably receives appendage portion  21  allowing the overall length of step assembly  6  to be extended to accommodate varying heights of dunk tanks and patrons for example. Sleeve and appendage portions  20  and  21  may include aligning apertures adapted to removably receive a securing pin, set screw, or the like to secure appendage portion  21  within sleeve portion  20  once a desired rail member length is achieved. Alternatively, appendage portion  21  may include pop-pins or the like that are received by aligning apertures of sleeve portion  20  to achieve the same results. For the exemplary purposes of this disclosure, appendage portion  21  may comprise approximately 1″ outside diameter square tubing, while sleeve portion  20  may comprise approximately 1¼″ outside diameter square tubing for the exemplary purposes of this disclosure. 
     In association with even other step assembly embodiments of the present invention, a step member may be removably coupled to the lower portion of the rail member and configured to be adjustable (i.e., moved and removably coupled and positioned at other operative locations) along a length of any rail member within the scope of the present invention to account for varying heights of dunk tanks and patrons, etc. For example, in FIG. 1, step member  22  may be removably coupled to the lower portion of rail member  18 . As depicted by the dashed outline of step member  22  approximately at a center portion of rail member  18 , step member  22  may be moved/adjusted and removably coupled and positioned at the position indicated or at any other operative locations along rail member  18 . Thus, step member  22  may be configured to adjust or the like in any manner or by any mechanism, such as those outline previous rail member embodiments, while still being able to couple to a rail member within the scope of the present invention. 
     Amusement dunk tank step assembly embodiments of the present invention may be formed of any of many different types of light weight, but sturdy/rigid materials or combinations thereof that can readily be formed into shaped objects, such as composites, polymers, fiber glass reenforced polymers, or other plastic like materials known in the art for example, metals, such as steel, galvanized steel, stainless steel, or corrosion-resistant metals like zinc or magnesium, or alloys, such as aluminum. Step assembly components may comprise any overall configuration, size, structure, and the like, including tubing, rods, beams, plates, panels, girders, brackets, frames, angles, channels, etc. For example, although some step assembly components illustrated in FIGS. 1-6 are substantially square-shaped in cross-section, these and other components might be any rectilinear or curvilinear shape in cross-section. 
     The components defining any amusement dunk tank step assembly embodiment of the present invention may be manufactured separately and then assembled together. However, the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve either injection molding, casting, milling, or the like. If any of the components are manufactured or bought separately, they may then be coupled with one another by any mechanism and in any manner known in the art, such as with adhesive, welds, fasteners, clamps, or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps are sand blasting or polishing the components and powder coating or painting to a desired color. 
     Accordingly, amusement dunk tank step assembly components of any embodiment of the invention, including an insertion member, an extension member, a retaining member, a rail member, a step member, a handle member, or any combination thereof, may be integrally joined to (i.e., unitary with) one another. For example, as depicted in step assembly embodiment  8  of FIG. 4, mounting member  11 , including insertion member  14  and extension member  17 , handle member  25 , rail member  19 , and step  23  are all integrally joined to one another. Nevertheless, in other step assembly embodiments within the scope of the present invention, only certain combinations of step assembly components may be integrally joined to one another, such as a handle member and an insertion member, while other component combinations are coupled together. Alternatively, step assembly components may not be unitary. 
     The present invention also provides an amusement dunk tank step system that includes a first step assembly and a second step assembly for allowing patrons to easily enter and exit a dunk tank. Although the present invention may be readily adapted to a variety of embodiments of an amusement dunk tank step system, with reference to FIG. 6, amusement dunk tank step system  48  is an example of a dunk tank step system of the present invention. 
     Amusement dunk tank step assembly embodiments of the present invention have previously been described, and the first step assembly of step system  48  is similar to or may be any one of the step assembly embodiments previously described. Accordingly, the first step amusement dunk tank assembly may be step assembly  2  for the exemplary purposes of this disclosure. Step assembly  2  may be removably mounted onto an upper back corner portion of dunk tank  32 . However, step assembly  2  may be removably mounted in a plurality of locations along an upper portion of dunk tank  32  depending on the location of components/equipment of amusement dunk tank system  30 , including platform  34  and step assembly  50 , for example. 
     With reference to FIGS. 5-6, step assembly  2  includes insertion member  12  configured to removably insert into an upper portion of dunk tank  32  in any manner when step assembly  2  is in an operative position. For example, insertion member is inserted into a vertically oriented, tubular, square-shaped framework element of dunk tank  32  in FIG.  6 . Handle member  24  is coupled to insertion member  12  and extends outwardly therefrom. A second portion of extension member  15  is coupled to retaining member  26  including a sleeve member into which are coupled handle member  24  and insertion member  12 . An upper portion of rail member  18  is coupled to a first portion of extension member  15 . Rail member  18  configured to be adjacent to an internal portion of dunk tank  32  when step assembly  2  is in an operative position. In dunk tank  32  of FIGS. 5-6, though not shown for clarity purposes, a tank insert comprises the internal portion of dunk tank  32 . Step member  22  is coupled to a lower portion of rail member  18 . Step member  22  is also configured to be adjacent to the internal portion (e.g. tank insert) of dunk tank  32  when step assembly  2  is in an operative position. 
     The second amusement dunk tank step assembly may be similar to or may be any one of the step assembly embodiments previously described as well. Accordingly, in association with one second amusement dunk tank step assembly embodiment of the present invention, the second step assembly includes a second mounting member configured to removably mount on an upper portion of dunk tank  32  for example. An upper portion of a second rail member is coupled to the second mounting member, the second rail member configured to be adjacent to an external portion of dunk tank  32  when the second step assembly is in an operative position. A second step member is. coupled to a lower portion of the second rail member, the second step member configured to be adjacent to the internal portion of dunk tank  32  when the second step assembly is in an operative position. Alternatively, the second step assembly may not include a second mounting member, and instead an upper portion of the second rail member may be coupled to mounting member  9  of first step assembly  2 . 
     As depicted in FIG. 6, in association with another second amusement dunk tank step assembly embodiment of the present invention and for the exemplary purposes of this disclosure, the second step assembly may be amusement dunk tank step assembly  50 , which includes bracket member  52 , pivot member  54 , and a step member  56 . Bracket member  52  may be either securely or removably coupled to an external portion of dunk tank  32  in any manner, and is typically opposite step  22  of step assembly  2  to facilitate entering and exiting dunk tank  32 . Bracket member  52  comprises opposing semicircular-shaped retaining portions, though any other configuration and the like is within the scope of the invention. Bracket member  52  may also comprise a stop portion that keeps step  56  in an operative position, such as the opposing square-shaped stop portion depicted in FIG. 6, though any other configuration and the like is within the scope of the invention. 
     Pivot member  54  is coupled to and retained by bracket member  52 . That is, ends of pivot member  54  are located in apertures of the opposing semicircular-shaped retaining portions so that pivot member  54  retained between the opposing semicircular-shaped retaining portions of bracket member  52 . Pivot member may be a circular rod or tubular portion for example, though any other configuration and the like is within the scope of the invention. 
     Step member  56  is coupled to pivot member  54  in any manner. For example, an end of step member  56  may be wrapped around pivot member  54 , or the end may be otherwise coupled thereto in any manner. Step  56  is configured to pivot between a substantially vertical position adjacent to the external portion of dunk tank  32  and a substantially operative, horizontal position perpendicular to the external portion of dunk tank  32 . Thus step  56  may pivot between approximately 0° to 100°. Step  56  may be any rectilinear or curvilinear configuration and may comprise a plate that is approximately ¼″ thick. 
     Describing the use of amusement dunk tank step assembly and system embodiments of the present invention further and for the exemplary purposes of this disclosure, reference is made to amusement dunk tank system  30  in FIGS. 5-6. Amusement dunk tank system  30  is a portable dunk tank system having a substantially square overall configuration, though any rectilinear or curvilinear shaped dunk tank and the like is within the scope of the invention. Amusement dunk tank system  30  has components/equipment and prefabricated framework panels each comprised of tubular square-shaped elements welded together, all of which are easily assembled onsite, easily disassembled, and easily transported from location to location. Notwithstanding, the invention may be utilized in virtually any amusement dunk tank system, including those previously described and of any size, configuration, or the like. 
     Particularly, amusement dunk tank system  30  includes dunk tank  32 . Although not illustrated, dunk tank system  30  has a soft vinyl dunk tank insert or other like material dunk tank insert that is secured to the upper portion of dunk tank  32  framework (such as by velcro straps) and contains fall-breaking fluid or material such as water. Platform  34  is collapsibly mounted on dunk tank  32  framework. Release mechanism member  36  is L-shaped having a first end coupled to platform  34 . Target  38  is coupled to a second end of release mechanism member  36 . Protection framework  40  may comprise similar materials as that of dunk tank  32  and/or may comprise a net for example. Protection framework  40  is mounted to the front (not shown) and sides of dunk tank  32  so that objects that are thrown at target  38  do not hit the patron sitting above dunk tank  32  on platform  34 . L-shaped side frame  42  extends laterally from tank  32  and coupled thereto is curtain  44  forming a backstop for target  38 . Curtain  44  may be plastic, canvas, cloth, netting, fencing, or any other material for example, and is mounted by any acceptable mechanism, such as hooks, or may be folded over itself and sewn so as to form a sleeve portion on the top thereof that slidably receives a portion of L-shaped side frame  42 . Step system  48  is also included and comprises step assemblies for allowing patrons to enter and exit a dunk tank. For the exemplary purposes of this disclosure, dunk tank step system  48  includes step assembly  50  and step assembly  2 , although any other step assembly embodiment may be included. 
     In operation, a patron enters dunk tank  32  utilizing step assembly  50  and handle  24 . With a foot, the patron may fold down step member  56 , place a foot thereon, grab handle  24 , and step and pull himself up in order to sit upon platform  34 . When target  38  is struck by people throwing objects, release mechanism member  36  is activated causing platform  34  to collapse. The patron is then dropped into fall-breaking fluid or material contained in the dunk tank insert. Unlike conventional dunk tank systems where the patron must negotiate his own way out of the dunk tank (e.g. by pushing and/or pulling himself up out of dunk tank  32  by trying to grab dunk tank framework or protection framework  40 ) to reseat himself upon the platform, step assembly  2  allows the patron in dunk tank  32  to easily exit dunk tank  32 . 
     Particularly, the patron places a foot on step  22 , grabs handle  24 , and steps and pulls himself up. Because of the configuration of step assembly  2  for example, step  22  is located at a height that positions the patron&#39;s body at a level that allows him to easily reseat himself upon the platform. The patron may then swing himself to face forward in preparation for being dunked again, or may swing himself to face rearward in preparation from exiting dunk tank system  30  all together using step assembly  50  and handle  24 . Additionally, dunk tanks and patrons come in a variety of sizes and shapes for example. Accordingly, step assembly  2  and other step assembly embodiments of the present invention that have extendable rail members, an adjustable step, or a plurality of steps for example will virtually always have a step or steps located at such a height that, when used, will position a patron&#39;s body at a level that allows him to easily reseat himself upon the platform. 
     Accordingly, amusement dunk tank step assemblies of the present invention overcome the aforementioned drawbacks of previous conventional amusement dunk tank systems. The invention provides an amusement dunk tank step assembly that includes a mounting member configured to removably mount on an upper portion of a dunk tank. An upper portion of a rail member is coupled to the mounting member and is configured to be adjacent to an internal portion of the dunk tank when the step assembly is in an operative position. A step member is coupled to a lower portion of the rail member and is configured to be adjacent to the internal portion of the dunk tank when the step assembly is in an operative position. Amusement dunk tank step assemblies of the present invention are thus configured to provide certain advantages including: positioning and allowing patrons dropped into dunk tanks to easily exit therefrom and reseat themselves upon platforms; removably mounting to dunk tanks easily in a plurality of locations; and/or retrofitting virtually any existing dunk tank and/or fitting virtually any newly manufactured dunk tank. Moreover, the step assembly and system of the present invention are easy to manufacture, assemble, and maintain.
