| 20090056154 | Collapsible level and utility device - The present invention resides in a collapsible level comprising a first segment; at least one additional segment, physically independent of the first segment and operable with the first segment to form the level; a leveling vial supported in at least one of the segments; and a linking member operable with the segments to permit the segments to be assembled and to secure an assembled relationship between the segments, as well as to maintain a connection between the segments when disassembled. In an alternative embodiment, the linking member is removed and the segments link together magnetically. The present invention further provides means for longitudinally extending the length of the collapsible level, thereby providing the collapsible level with the ability to level a wide range of shaped and sized surfaces. The present invention further resides in an accessory device operable with a level to enhance the functionality of the level, the accessory device comprising: a housing; and means for attaching the housing to the level in both a removable and slidable manner. | 03-05-2009 |
| 20090071023 | LEVEL - An object is to provide a novel level in which a mounting base can be pressingly fixed in a container case in a reliable manner by a simple operation while having a simple configuration, wherein the level has excellent mass-productivity and is advantageous in terms of cost. The level is composed of a mounting base | 03-19-2009 |
| 20100000107 | Folding carpenter's level - A folding carpenter's level is disclosed which has two level segments, each of which has a smooth flat top and bottom surface, that are hingeably attached at a distal tip by means of a recessed, flat hinging means. The two level segments can be rotated laterally in the plane of the level so as to be oriented with respect to each other at angles of from 0 to 180 degrees, thus effectively doubling the length of the level. At least one of the level segments has one or more tubular spirit vials attached to the segment for measuring the levelness of the top surface with respect to horizontal. The level segments usually have additional tubular spirit vials oriented vertically to allow the tool to be used to measure plumb. Such tubular spirit vials are generally located in apertures so that the spirit bubble in the vials can be seen from the front or the back of the folding level. The folding level can beneficially include other recessed features, such as a fastening means to hold the segments together in a folded configuration, and a locking means to hold the segments secure when the segments are rotated 180 degrees with respect to each other so that the tops of the segments form a smooth flat surface with a straight edge. | 01-07-2010 |
| 20110107609 | Window frame deflection measurement device and method of use - A portable device for measuring deflection of a surface, comprising an elongate frame having a first end and a second end and a first datum surface, a first removable reference assembly adjacent the first end, a second removable reference adjacent the second end, a deflection gauge attached to the elongate frame between the first removable reference assembly and the second removable reference assembly, and wherein the deflection gauge engages and measures a deflection of the surface relative to the first removable reference assembly and the second removable reference assembly. | 05-12-2011 |
| 20130167387 | MULTI-FUNCTION LEVEL WITH A JOINABLE END - An apparatus and method for measuring and marking level and plumb is providently disclosed herein. The multi-function level includes: modular ends that allow attachment of mating levels for linear extension in one direction. The modular, or jointed, end includes a structure to hold a connector or to selectively receive a connector from another level such that that only applies a load to the jointed end and not the body of the level. | 07-04-2013 |

| 20090113733 | EXTENDABLE PLUMB AND LEVEL MEASURING DEVICE AND ASSOCIATED USAGE METHOD - The present disclosure includes an extendable plumb and level measuring device and associated usage method. The device can utilize interconnected members including a first, a second, and a third member. For example, the third member can be slidingly disposed within the first and second members to extend the device to a set and arbitrary length. The measuring device utilizes a spirit level or digital reader to determine when the device itself is level responsive to positioning a extendable stopper against a construction, such as a wall, door, panel, and the like. Once level, a measuring device, such as a ruler, disposed within the device can be utilized to measure the plumb of the construction. Additionally, the device can function as an extendable level to measure an arbitrary length. | 05-07-2009 |
