Abstract

Provided is a stud finder for determining the location of a stud within a wall. The stud finder includes a body having an internal compartment formed therein which is sized and configured to house a magnetic element therein. The stud finder is moveable along the wall to place the magnetic element in magnetic attraction with metallic fasteners (i.e., nails, screws, etc) disposed within the stud, such as for securing drywall to the stud. The magnetic attraction urges the magnetic element toward the metallic element to provide a visual indication as to the precise location of the metallic element, as well as the underlying stud.

Claims

1. A stud finder for use in locating a stud having a metallic element disposed therein, the stud finder comprising:

a body having an internal compartment; and

a magnetic element irremovably confined within the internal compartment and freely moveable therein, wherein the magnetic element is not restricted about any axis within the internal compartment;

the body and magnetic element being configured such that the magnetic element is magnetically attracted to the metallic element located exteriorly to the body when the internal compartment is disposed adjacent the metallic element.

2. The stud finder as recited in claim 1, wherein:

the body is elongate and includes a plurality of internal compartments formed therein and aligned in an axial array; and

the magnetic element includes a plurality of magnetic elements, each magnetic element being disposed within a respective one of the plurality of internal compartments.

3. The stud finder as recited in claim 2, wherein each internal compartment is spaced from an adjacent one of the plurality of internal compartments.

4. The stud finder as recited in claim 2, wherein each internal compartment is spaced from an adjacent one of the plurality of internal compartments such that the magnetic elements disposed in adjacent compartment are magnetically isolated from each other.

5. The stud finder as recited in claim 2, wherein the body defines a longitudinal axis, each internal compartment defining a longitudinal center along the longitudinal axis, the longitudinal centers of adjacent internal compartments being spaced less than six inches.

6. The stud finder as recited in claim 1, wherein the body includes a transparent wall having an inner surface defining at least a portion of the internal compartment and an outer surface defining at least a portion of an external surface of the body wherein said magnetic element is viewable in the body.

7. The stud finder as recited in claim 1, wherein the body includes a first end and an opposing second end to define a body length therebetween, the body length being sixteen inches.

8. The stud finder as recited in claim 1, wherein the body includes a planar exterior surface configured to be disposable adjacent the wall.

9. The stud finder as recited in claim 1, wherein the body and magnetic element are configured to emit an audible detection signal and a visual detection signal in response to the stud finder being aligned with the metallic fastener.

10. The stud finder as recited in claim 9, wherein the audible detection signal is generated by contact between the magnetic element and the body.

11. The stud finder as recited in claim 1, wherein the body is formed from a transparent material.

12. The stud finder as recited in claim 1, wherein the body is formed from a plastic material.

13. The stud finder as recited in claim 1, further comprising a level connected to the body, the level configured to indicate one of a horizontal axis and a vertical axis.

14. The stud finder as recited in claim 1, wherein the magnetic element is detached from the body.

15. A stud finder for detecting the location of a stud within a wall, wherein the stud includes a metallic fastener inserted within the stud, the stud finder comprising:

a body having an internal compartment formed therein and having inner walls forming said inner compartment; and

a magnetic element irremovably confined within the internal compartment and freely moveable therein, the magnetic element being magnetically attractable to the metallic fastener through an inner wall such that the magnetic element remains stationary relative to the metallic fastener as the body is moved adjacent the metallic fastener.

16. The stud finder as recited in claim 15, wherein:

the body includes a plurality of internal compartments formed therein; and

the magnetic element includes a plurality of magnetic elements, each magnetic element being disposed within a respective one of the plurality of internal compartments.

17. The stud finder as recited in claim 16, wherein each internal compartment is spaced from an adjacent one of the plurality of internal compartments such that the magnetic elements disposed in adjacent compartment are magnetically isolated from each other.

18. The stud finder as recited in claim 15, wherein the magnetic element is moveable relative to the body about at least two axes.

19. The stud finder as recited in claim 15, wherein the body is formed from a transparent material.

20. A stud finder for use in locating a stud having a metallic element disposed therein, the stud finder comprising:

an elongate body having an internal compartment; and

a magnetic element irremovably confined within the internal compartment and freely moveable within the body, wherein the magnetic element is not restricted about any axis within the internal compartment, the magnetic element being configured to be magnetically attracted to the metallic element when the internal compartment is disposed adjacent the metallic element;

the body and magnetic element being configured to provide a visual confirmation of magnetic attraction between the magnetic element and the metallic element.

21. The stud finder as recited in claim 20, wherein the body and magnetic element are configured to collectively provide an audible confirmation of magnetic attraction between the magnetic element and the metallic element.
