BACKGROUND OF THE INVENTION
The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
TECHNICAL FIELD
The present invention relates generally to the field of hand tools of existing art and more specifically relates to leveling devices.
RELATED ART
In construction and related fields, it is frequently desirable and necessary to orient structural members in a manner which is level with true horizontal. In other situations, it may be likewise necessary to orient members at a particular angle to true horizontal. Leveling in this way is necessary because it allows engineers and contractors to maintain reference points for making measurements and placing adjacent structural members.
Commonly, leveling tools are constructed in a way that allows them to orient a member to either zero or ninety degrees from true horizontal. However, other angles are often needed in the construction industry, particularly for roof trusses, braces, railings, and similar structures. A suitable solution is desired.
U.S. Pat. No. 7,152,335 to Michael P. Nichols relates to an omnidirectional torpedo level having magnetic mounts and adjustable protractor. The described omnidirectional torpedo level having magnetic mounts and adjustable protractor includes an omnidirectional torpedo level composed of non-ferrous material having a central web and parallel side flanges defining a torpedo level geometry. The central web and side flanges define windows within which are mounted vertical and horizontal tubular spirit level elements that permit selective orientation of the side flanges to determine when surfaces being engaged by the side flanges are either vertically or horizontally oriented. A rotary protractor is mounted to the central web and contains a spirit level tube for accurate positioning of the side flanges with respect to the selected angle of the protractor.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known leveling device art, the present disclosure provides a novel multi-directional magnetic leveling device and method. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a multi-directional magnetic leveling device and method.
A leveling tool is disclosed herein. The leveling tool includes a level frame having four flat exterior faces able to be placed against a workpiece, four transparent reservoirs containing fluid and air, and magnets integrated within the level frame. The exterior faces may be disposed perpendicularly to each other, such that they form a rectangle. The reservoirs may be disposed within the level frame such that they and their contents are visible to a user when one of the exterior faces is placed against a workpiece. The reservoirs are oriented at angles of zero, thirty, forty-five, and ninety degrees relative to one of the exterior faces, respectively. This variety of exterior faces and angled reservoirs allows the reservoirs to be used to indicate level of a workpiece if the workpiece is oriented at any summation of zero, thirty, forty-five, and ninety degrees of level. The magnets within the level frame allows the level frame to be removably coupled to a ferrous workpiece.
According to another embodiment, a method of leveling a workpiece is also disclosed herein. The method of leveling a workpiece includes providing the above-described leveling tool, placing one of the four exterior surfaces adjacent to the workpiece, examining the appropriate bubble reservoir to determine if the air is centered within the fluid, thereby indicating level, and optionally, adjusting the workpiece until the air is centered within the fluid.
For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein. The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description.

DETAILED DESCRIPTION
As discussed above, embodiments of the present disclosure relate to a leveling device and more particularly to a multi-directional magnetic leveling device and method as used to improve the determination of levelness of a workpiece.
Generally, the leveling device is a multi-angle spirit level having magnets able to attaches to steel surfaces and structures. The inclusion of magnets enables individuals to level ferromagnetic objects in a hands-free manner quickly and easily. The leveling device has a cuboid body, with six faces related perpendicularly, making leveling from different sides of the level intuitive to a user. The magnets may be included on multiple sides of the level, further allowing users to attach the level to all metal surfaces from multiple sides. A preferred embodiment includes magnets positioned on all six sides of the cuboid body of the level. The leveling device is advantageous for use by any craftsman who must level a ferromagnetic object, such as electricians, ironworkers, steamfitters, and metal stud workers, by reducing the need to use both hands or more than one individual to level an object. In a preferred embodiment, the cuboid level may measure approximately nine inches long, one-and-five-eighths inched tall, and five-eighths of an inch thick. The level may contain four glass level bulbs and nine magnets for attaching to a steel structure from any side. The four bulbs may be oriented at zero, thirty, forty-five, and ninety degrees relative to one side of the level respectively. The exact specifications may vary.
Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a tool 100.
FIG. 1 shows a bubble level during an ‘in-use’ condition 50, according to an embodiment of the present disclosure. Here, the bubble level may be beneficial for use by a user 40 to orient a member at a desired angle relative to true horizontal. As illustrated, bubble level 100 may be useful for measuring inclinations of a ferromagnetic surface 10 relative to a ground 5.

The bubble level 100 may include a frame 110, a horizontal bubble tube 120, a vertical bubble tube 122, a 45-degree bubble tube 124, a 30-degree bubble tube 126, and at least one first magnet 140. The level-frame 110 may include a first flat surface 112, which may be configured to rest against the ferromagnetic surface 10 (FIG. 1), in which event the first flat surface 112 may define a first surface inclination 113. The horizontal bubble tube 120 may be fixed to the level-frame 110 and may be configured to indicate when the first surface inclination 113 is horizontal. Likewise, the vertical bubble tube 122 may also be fixed to the level-frame 110 and may be configured to indicate when the first surface inclination 113 is vertical.
