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;
- and
- a first chamber formed in the base surface, the first chamber comprising:
- a chamber floor;
- an internal wall extending from a periphery of the chamber floor to the base surface;
- a chamber volume defined by the internal wall and the chamber floor;
- a flange protruding outwardly from the internal wall, the flange partially protruding over the chamber volume;
- a magnet disposed in the chamber volume;
- and
- a biasing component in the chamber volume, the magnet biased against the flange by the biasing component.
A level comprising:
- an orientation measuring component;
- a planar base surface;
- a top surface opposing the base surface;
- and
- a first chamber formed in the base surface, the first chamber comprising:
- a chamber floor;
- an internal wall extending from a periphery of the chamber floor to the base surface;
- a chamber volume defined by the internal wall and the chamber floor;
- and
- a magnet disposed in the chamber volume, wherein the chamber volume does not include an adhesive that secures the magnet within the chamber volume.
A level comprising:
- an orientation measuring component;
- a planar base surface;
- a top surface opposing the base surface;
- and
- a chamber formed in the base surface, the first chamber comprising:
- a chamber floor;
- an internal wall extending from a periphery of the chamber floor to the base surface;
- a chamber volume defined by the internal wall and the chamber floor;
- a magnet disposed in the chamber volume;
- and
- a flange protruding outwardly from the internal wall, the flange interfacing with the magnet, wherein the flange and the internal wall surrounding the chamber are collectively formed from a single piece of material.
