Abstract
A stud finder for detecting ferrous objects hidden within a wall, such as nails and screws, comprising a tray having at least one cavity, a magnet, and a cover. The magnet placed within the cavity and secured by the cover. The magnet is free to move within the cavity when a force, such as gravity or magnetic, is applied. As the stud finder is slid across a wall, a magnet will move within the cavity when it comes into proximity of a ferrous material such as a screw or nail. The movement is caused by magnetic force. The presence of the magnetic force indicates the presence of a screw or nail which also indicates the presence of a stud.

A stud finder comprising:
- a rigid non-ferrous base having
- a first surface,
- a second surface parallel to and opposite the first surface;
- and
- at least two cavities each having a bottom that is parallel to the second surface, a sidewall that is perpendicular to the bottom, and an opening through the first surface;
- a transparent cover having a top surface and bottom surface wherein the cover is attached to the first surface of the base with the bottom surface of the cover positioned over the opening of each cavity;
- and
- at least one magnet having a top surface, bottom surface, and at least one sidewall positioned within each cavity and moveable within each cavity so long as the top surface of the magnet is adjacent the bottom surface of the cover and the bottom surface of the magnet is adjacent the bottom of the cavity.
A stud finder system comprising:
- stud finder comprising:
- a rigid non-ferrous base having
- a first surface,
- a second surface parallel to and opposite the first surface;
- and
- at least two cavities each having a bottom that is parallel to the second surface, a sidewall that is perpendicular to the bottom, and an opening through the first surface;
- a transparent cover having a top surface and bottom surface wherein the cover is attached to the first surface of the base with the bottom surface of the cover positioned over the opening of each cavity;
- and
- at least one magnet having a top surface, bottom surface, and at least one sidewall positioned within each cavity and moveable within each cavity so long as the top surface of the magnet is adjacent the bottom surface of the cover and the bottom surface of the magnet is adjacent the bottom of the cavity;
- and
- place marker comprising a body and magnet.
A method of detecting a ferrous material in a wall comprising the steps of:
- placing a stud finder flush against the wall wherein the stud finder comprises:
- a rigid non-ferrous base having
- a first surface,
- a second surface parallel to and opposite the first surface;
- and
- at least two cavities each having a bottom that is parallel to the second surface, a sidewall that is perpendicular to the bottom, and an opening through the first surface;
- a transparent cover having a top surface and bottom surface wherein the cover is attached to the first surface of the base with the bottom surface of the cover positioned over the opening of each cavity;
- and
- at least one magnet having a top surface, bottom surface, and at least one sidewall positioned within each cavity and moveable within each cavity so long as the top surface of the magnet is adjacent the bottom surface of the cover and the bottom surface of the magnet is adjacent the bottom of the cavity;
- and
- sliding the stud finder across the wall until a magnet moves within the cavity;
- placing a place marker on the wall where the magnet moved wherein the place marker comprises a body and magnet.
