Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial. | 05-19-2016 |
20160138917 | LEVEL INCLUDING A SLOT FOR RECEIVING A STRAIGHT EDGE - A level including a first plate defining a top surface of the tool, and a second plate defining a bottom surface of the tool. The bottom plate extends generally parallel to the first plate. The level also includes a center plate having two opposing side surfaces extending generally perpendicular to the first plate and the second plate. The center plate connects the first plate and the second plate. The level further includes a plurality of apertures extending through the center plate, and a plurality of tubular vials disposed within the plurality of apertures. Each tubular vial contains fluid and air. The level also includes a slot extending along the first plate from a first end of the tool to a second end of the tool. The slot is configured to receive a straight edge. | 05-19-2016 |
20160138918 | LEVEL INCLUDING REMOVABLE END CAPS - A level includes a frame supporting a plurality of vials and having an aperture disposed on an end of the level. The level also includes an end cap assembly detachably coupled to the end of the frame. The end cap assembly includes an end cap and a retainer. A portion of the end cap is received in the aperture and is maintained in engagement with the frame by the retainer. | 05-19-2016 |

20090277026 | Offset level - Devices for commercial, industrial, professional and household use are described in offset levels. In one embodiment, the offset level may comprise at least two parallel but offset portions such that an individual may use the offset level to lay a level line even if here is an object in the way which would prevent use of an conventional straight level. In one embodiment, the offset level comprises at least three portions, two of which are co-axial and a third which is not co-axial with the other two and which is therefore offset. | 11-12-2009 |
20090313839 | LEVEL - A level includes a body having first and second arms attached to each other for relative pivotal movement about a pivot axis between open and closed positions. The level also includes a bubble vial mounted to the body and having a longitudinal axis coaxial with the pivot axis. Movement of the arms from their closed position to their open position exposes a measurement portion of the first bubble vial for use. Movement of the arms from their open position to their closed position shields the measurement portion of the first bubble vial within the body to protect the bubble vial from damage during storage. | 12-24-2009 |
20100257745 | SPIRIT LEVEL - A spirit level comprises a planar base that functions, with the level in a first orientation, as a first level face which rests, in use, on a surface of an item whose level is to be determined. The level is further provided with leveling means comprising first and second vials each filled with a liquid to form a bubble, the longitudinal axis of the first vial being substantially parallel to the plane of the planar base, the longitudinal axis of the second vial being substantially perpendicular to the longitudinal axis of the first vial. Optical means are provided to provide an image of one of the vials such that the level of the surface can be determined about two axes, with the planar base resting on the surface of the item whose level is to be determined. | 10-14-2010 |
20130091717 | LEVEL - A level for indicating the orientation of a surface includes a first planar surface, a second planar surface, a web coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface, and a vial having a long axis and containing a liquid and a gas bubble. The level also includes a first magnet coupled to the first planar surface, a second magnet coupled to the first planar surface and spaced apart from the first magnet by a first distance, and a third magnet coupled to the first planar surface and spaced apart from the second magnet by a second distance that is different than the first distance. The first, second, and third magnets are positioned along the first planar surface successively without any additional magnets positioned therebetween. | 04-18-2013 |
