DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new level device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the level assembly 10 generally comprises an elongated housing 12 having a first end 14, a second end 16 and a perimeter wall 18 extending between the first 14 and second 16 ends. The perimeter wall 18 includes a front wall 20, a back wall 22, a first side wall 24 and a second side wall 26. The housing 12 has a plurality of apertures 28 therein. Each of the apertures 28 extends into the front wall 20.
A plurality of bubble levels 30 is provided. Each of the apertures 28 has one of the levels 30 mounted therein. At least one of the levels 30 is orientated horizontally when a longitudinal axis of the housing 12 is horizontally orientated and at least one of the levels 30 is orientated vertically when the longitudinal axis of the housing 12 is horizontally orientated. The longitudinal axis of the housing 12 extends through the first 14 and second 16 ends. A plurality of coverings 32 is attached to the housing 12. Each of the apertures 28 is covered with one of the coverings 32. As shown in FIG. 2, the apertures 28 may extend through the back wall 22 and then coverings 32 are also attached to the back wall 22 to cover the apertures 28 here as well.
A plurality of light emitters 34 is mounted in the housing 12. Each of the apertures 28 has one of the light emitters 34 directed therein. The light emitters 34 illuminate adjacently positioned ones of the levels 30 when the light emitters 34 are turned on. The light emitters 34 may comprise light emitting diodes. As shown in FIG. 4, two light emitters 34 may be directed into each of the apertures 30 and positioned on either side of the levels 30 to ensure that the levels 30 are viewable from multiple angles. A power supply 36 is mounted within the housing 12 and is electrically coupled to the light emitters. The power supply 12 may combine one or more batteries removably positioned in a battery compartment located within the housing 12 and accessed through a removable panel 38. An actuator 40 is mounted on the housing 12 and is electrically coupled to the power supply 38. The actuator 40 is actuated to turn the light emitters 34 on or off.
A laser range finder 42 is mounted in the housing 12 to determine a distance between two walls positioned on opposite sides of the housing 12. The laser range finder 42 includes a first laser light emitter 44 that is mounted in the first end 14 and is directed outwardly of the housing 12. The first laser light emitter 44 emits a laser beam orientated perpendicular to the vertically orientated bubble level 30. A first light detector 46 is mounted in the first end 14 and detects reflected light from the first laser light 44. A second laser light emitter 48 is mounted in the second end 16 and is directed outwardly of the housing 12. The second laser light emitter 48 emits a laser beam orientated perpendicular to the vertically orientated bubble level 30. A second light detector 50 is mounted in the second end 16 and detects reflected light from the second laser light 48. A display 52 is mounted in the housing 12 and is electrically coupled to a processor 54 electrically coupled to the first 44 and second 48 light detectors. The processor 54 is programmed in a conventional manner for range finders and the first 44 and second 48 laser light emitters and first 46 and second 48 light detectors are also conventional for laser finders. Additionally, the processor 54 may be programmed to determine the distance from just one of the laser light emitters 44, 48 to a wall surface if only one of the laser light emitters 44, 48 is detecting light such as if one of the first 14 or second 16 ends is in abutment with a wall surface. The display 52 may be a liquid crystal display which displays the distance between oppositely positioned walls.
In use, the housing 12 is used in a conventional manner to check the orientation of an object. The assembly 10 may include levels 30 of varying orientations depending on the need and usage of the person utilizing the assembly 10. The light emitters 34 provide illumination for the levels 30 to ensure that the person can adequately see the levels 30. If needed, the range finder 42 may be used for measuring distances between two points or between the housing 12 and another point.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and 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 an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
