## Title
Water-filled stairs

## Abstract

The water-filled stairs involves a modular staircase that is to be used on a temporary basis, and which is of hollowed construction so as to be filled with water when in use for the purpose of weighing down the staircase. The water-filled stairs is further defined with a plurality of steps adorning a top surface, and a flattened bottom surface. Distal ends of the water-filled stairs include a hook or connecting bar such that consecutive staircases may be attached to accommodate the needs of a particular application. Each staircase includes a male threaded port adjacent a top distal end as well as a bottom distal end. A flexible hose attaches in between the male threaded ports of adjacent staircases in order for a single water source to fill all staircases simultaneously.

Each staircase includes a male threaded port adjacent a top distal end as well as a bottom distal end. A flexible hose attaches in between the male threaded ports of adjacent staircases in order for a single water source to fill all staircases simultaneously.
An object of the invention is to provide a temporary staircase design that is modular, and which can be easily installed to provide a safe staircase for outdoor use.
Another object of the invention is for the water-filled stairs to be filled with water in order to weigh down the staircase(s) for use.
Another object of the invention is for the staircases to be modularized such that a plurality of staircases may be attached linearly to accommodate the particular use.
Another object of the invention is for the staircases to include male-threaded ports in order to fill or drain the respective staircase with water.
These together with additional objects, features and advantages of the water-filled stairs will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the water-filled stairs when taken in conjunction with the accompanying drawings.
In this respect, before explaining the current embodiments of the water-filled stairs in detail, it is to be understood that the water-filled stairs is not limited in its applications to the details of construction and arrangements of the components set forth in the following description or illustration.

DETAILED DESCRIPTION OF THE EMBODIMENT
The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.
As best illustrated in FIGS. 1 through 5, the water-filled stairs 100 (hereinafter invention) generally comprises a staircase housing 101 that is further defined with a plurality of steps 102 adorning a top surface 103. The staircase housing 101 is further defined with a flat bottom surface 104, which is opposite the top surface 103. The steps 102 may include tread 105 thereon to aid in providing traction when being stepped upon.
The staircase housing 101 is of hollowed construction, and is further defined with a left side surface 106 as well as a right side surface 107. The left side surface 106 or the right side surface 107 is provided with a pair of male threaded port members 110. The male threaded port members 110 being provided adjacent to a top distal edge 108 and a bottom distal edge 109. The male threaded port members 110 are important in that the staircase housing 101 may be fully or partially filled with water 200. The invention 100 is configured to be filled with water 200 in order to weigh down the invention 100 during use.
The male threaded port members 110 may include a screw on cap 111 to seal off the male threaded port members 110 between filling or draining of the water 200. Moreover, the invention 100 may utilize a flexible conduit 120 to connect to two consecutive staircase housings 101. That being said, the invention 100 is modular in that a plurality of staircase housings 101 may be connected linearly in order to defined a use length 130 as needed.
The flexible conduit 120 enables the two consecutive staircase housings 101 to be filled or drained of the water 200 simultaneously. Moreover, the bottommost of the male threaded port members 110 shall be opened in order to drain water 200 from all connected staircase housings 101. Moreover, the topmost of the male threaded port members 110 shall be opened in order to fill the staircase housings 101 with water 200.
The top distal edge 108 of the staircase housings 101 includes a hook member 150 whereas the bottom distal edge 109 includes a connecting bar member 151. The hook member 150 enables the staircase housing 101 to be hooked onto the connecting bar member 151 of an adjacent staircase housing 101.
Referring to FIG. 5, the invention 100 is configured to lie atop of a surface 300 in order to provide a plurality of steps for walking into or out of a body of water 301. It shall be noted that the invention 100 is intended to be used on a temporary basis, and shall be removed upon emptying all of the water 200 from within all staircase housings 101.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention 100, to include variations in size, materials, shape, form, function, and the manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention 100.
It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
