The present invention relates generally to flooring installation and removal tools, and more particularly to a tool for removing panels from a raised floor system.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Raised floors are commonly used where large numbers of computers are operating such as data rooms, and call centers, for example. Typical raised floor systems utilize a plurality of individual panels that are positioned along a frame to create a space between the sub-floor and the normal working environment of the room. As the name implies, the sub-floor is the surface that would serve as the floor of the data center prior to the installation of a raised flooring system. The space created by such systems typically includes a height of between 6 and 12 inches and are used to house any number of different components such as electrical wiring, telephone wiring, computer cables, and/or HVAC components, for example which are needed but are more safely or conveniently enclosed in an area apart from the main area of the data center room.
Although the primary purpose of the raised flooring system is to structurally support an applied load, the space between the floors must be accessed periodically for maintenance, repairs, installation and/or replacement of certain components. To this end, it is important that certain of the individual panels be removeable to provide access to this area. Although there are known tools for removing lightweight floor panels of less than 50 pounds using suction cups attached to a handle, these systems are not able to be used with heavy duty floor systems (e.g., individual panels weighing more than 50 pounds) whose panels are constructed from steel, ceramic or concrete, for example. Indeed, the most difficult aspect of removing these panels is the ability to engage and lift the panel from its horizontal resting position so that it can be removed.
Moreover, depending on the size of the room and the location of the components which must be accessed, it is not uncommon for a worker to have to engage, lift and remove multiple panels at one time. During this period, the normal operation of the room is interrupted which costs the operations company time and money. In some instances, this can be tens of millions of dollars. Accordingly, it would be beneficial to provide a raised floor panel tool that allows workers to quickly engage and lift a portion of a floor panel so the same can be removed, without suffering from the drawbacks described above.
The present invention is directed to a tool for removing raised flooring panels. One embodiment of the present invention can include a generally J-shaped body having a first vertical bar, a second vertical bar and a horizontal bar that is connected to the vertical bars along the respective bottom ends. A handle is positioned along the top of the first vertical bar and is positioned perpendicular to the horizontal bar.
In one embodiment, the tool components can be constructed from steel tubing and can be joined together by a plurality of steel tube elbows and a T-shaped connector. In this embodiment, the handle can include an electrically insulative material such as rubber grips for protecting a user from electrical shock and for aiding in manipulating the tool.
In one embodiment, the tool can also include a pair of wheels that can be attached to the bottom end of the first vertical bar by a bracket. The wheels and bracket can function to aid a user in rotating the tool during operation. In one embodiment, the second vertical bar can include an adjustable height so as to permit the tool to be used with raised floor systems having any number of different heights from the sub floor.
This summary is provided merely to introduce certain concepts and not to identify key or essential features of the claimed subject matter.
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.
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.
As described throughout this document, the term “about” “approximately” “substantially” and “generally” shall be used interchangeably to describe a feature, shape or measurement of a component within a tolerance such as, for example, manufacturing tolerances, measurement tolerances or the like.
As described herein, the term “removably secured,” and derivatives thereof shall be used to describe a situation wherein two or more objects are joined together in a non-permanent manner so as to allow the same objects to be repeatedly joined and separated.
As described throughout this document, the term “complementary shape,” and “complementary dimension,” shall be used to describe a shape and size of a component that is identical to, or substantially identical to the shape and size of another identified component within a tolerance such as, for example, manufacturing tolerances, measurement tolerances or the like.
As described herein, the term “connector” includes any number of different elements that work alone or together to repeatedly join two items together in a nonpermanent manner. Several nonlimiting examples include opposing strips of hook and loop material (i.e., Velcro®), attractively-oriented magnetic elements, flexible strips of interlocking projections with a slider (i.e., zipper), a thin, flexible strap with a notched surface and one end threaded through a locking mechanism (i.e., zip tie) at the other, tethers, buckles such as side release buckles, and compression fittings such as T-handle rubber draw latches, hooks, snaps and buttons, for example. Each illustrated connector and complementary connector can be permanently secured to the illustrated portion of the device via a permanent sealer such as glue, adhesive tape, or stitching, for example.
As shown in the drawings, the tool 10 can include a generally J-shaped main body member having a handle 11, a first vertical bar 12, a horizontal bar 13 and a second vertical bar 14. The first and second vertical bars can be positioned parallel to each other and can be connected along their respective bottom ends by the horizontal bar. Likewise, the handle 11 can be oriented generally perpendicular to the horizontal bar 13.
In one embodiment, each of the handle 11 and the bars 12-14 can be constructed from steel round tube and can be removably joined together by connectors such as steel tube elbows 15a/15b and a steel tube T-connector 16, for example. Of course, the main body is not limited to this construction material, as other embodiments are contemplated wherein different materials are used and/or wherein the tool components are permanently joined together and/or include a unitary construction.
Several nonlimiting examples of possible construction materials also include but are not limited to various other types of metals or metal alloys (e.g., aluminum, titanium, or alloys thereof), various plastic/polymers (e.g., high-density polyethylene (HDPE), rigid polyvinyl chloride (PVC), or polyethylene terephthalate (PET)), and/or various composite materials (e.g., carbon fibers in a polymer matrix, etc.). Moreover, other embodiments are contemplated wherein the main body is constructed from a single piece of material that is formed or molded into the described shape.
Because the tool will preferably be constructed from steel, the preferred embodiment of the tool can include an electrically insulative material 17 such as rubber, for example that is provided along the handle 11. The use of rubber grips on the handle functioning to insulate the worker from a possible electrical shock should the device encounter a live electrical wire, while advantageously and simultaneously improving the ability of the worker to grip and manipulate the tool.
Because raised floor panels are typically suspended between 6 and 12 inches from the sub floor, and the device 10 functions as a fulcrum to lift the panels, the dimensions of the device are important. To this end, the device can preferably include the following dimensions: first vertical pipe 12 having a height (e.g., distance between connectors 15a and 16) of approximately 54 inches; horizontal pipe 13 having a length (e.g., distance between connectors 15a and 15b) of approximately 12 inches; and second vertical pipe 14 having a height (e.g., distance between connector 15b and distal end) of approximately 12 inches. Such dimensions being chosen specifically to engage floor sections located 6 inches to 12 inches from the sub floor. Of course, any number of other dimensions are also contemplated.

Accordingly, the above-described tool functions to quickly and easily engage and lift removable floor panels in a novel manner.
As described herein, one or more elements of the raised floor panel removal tool 10 can be secured together utilizing any number of known attachment means such as, for example, screws, glue, 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 individually identified elements may be formed together as one or more continuous elements, 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.
As to a further description of the manner and use of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
