Abstract
A tool, such as a level, with magnets embedded in a working surface is provided. For example, the magnets assist in coupling the level to magnetic workpieces. The magnets are placed in a chamber with a floor having a periphery and internal walls extending from the floor periphery. Flanges extend from internal wall of the chamber toward a central axis or point and partially further define the chamber volume. Flanges may be created by depressing surface of the level near the chamber, thus deforming the level body surface to create a channel and a flange from the material displaced from the channel.
Claims20
A level comprising:
- an orientation measuring component;
- a planar base surface;
- a top surface opposing the base surface;
- a first chamber formed in the base surface, the first chamber comprising:
- a chamber floor with a periphery;
- an internal wall extending from the chamber floor periphery to the base surface;
- a chamber volume defined by the internal wall and the chamber floor;
- a compressible component adjacent to the chamber floor;
- a magnet disposed in the chamber volume such that the compressible component is between the magnet and the chamber floor;
- a flange protruding outwardly from the internal wall toward a middle of the first chamber, the flange partially protruding over the chamber volume and partially over the magnet such that the flange retains the magnet within the chamber volume.
A level comprising:
- a planar base surface;
- a top surface opposing the base surface;
- a level vial supported between the base surface and the top surface;
- a first chamber formed in the base surface, the first chamber comprising:
- a chamber floor with a periphery;
- an internal wall extending from the chamber floor periphery to the base surface;
- a chamber volume defined by the internal wall and the chamber floor;
- a compressible component adjacent to the chamber floor;
- a magnet disposed in the chamber volume such that the compressible component is between the magnet and the chamber floor;
- a flange that protrudes outwardly from the internal wall toward a middle of the first chamber, the flange partially protruding over the chamber volume, wherein the flange includes two flanges, and wherein the internal wall has a first diameter at a first location between the two flanges, the first diameter being less than a second diameter that is directly below the two flanges.
A level comprising:
- an orientation measuring component;
