DETAILED DESCRIPTION

[0029] The illustrated embodiments are disclosed with reference to the drawings. However, it is to be understood that the disclosed embodiments are intended to be merely examples that may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. The specific structural and functional details disclosed are not to be interpreted as limiting, but as a representative basis for teaching one skilled in the art how to practice the disclosed concepts.

[0030] FIG. 1 shows a non-contact voltage tester 10 being held by a hand 12. The tester 10 has hand-held elongate casing member 14 having a first end 16 and a second end 18. The second end is configured to be held by the hand 12 of a user. In at least a portion of the first end 16 is a sensor (not shown). The sensor is electrically connected to a circuit (not shown), which in turn is also connected to an indicator 22. The circuit is at least partially disposed within the casing member 14, and in conjunction with the sensor are configured to, when the sensor (or more specially the portion of the first end 16 that the sensor resides) is placed within a proximity of an alternating current electrical power source, provide an indication via the indicator 22 of the presence of the alternating current. This may be done by illuminating the indicator 22 when an AC source is encountered. Some testers 10 may utilize an audible device as the indicator 22, such as a buzzer. In FIG. 1, the first end 16 is being placed into a lightbulb socket 30. This lightbulb socket 30 is shown having a female Edison screw 32.

[0031] FIG. 2 is a perspective view of one embodiment of a removable lightbulb socket adapter 40 for a hand-held non-contact voltage tester 10, similar to the one shown in FIG. 1. This adapter 40 is configured to be held in a lightbulb socket 30, similar to the one shown in FIG. 1. Adapter 40 has a body 42, and as shown here may be a substantially circular body 42. Substantially, as used here, means that it does not have to be perfectly circular, rather that it is circular, but could be ovular or any shape that can provide a structural member for the further needed elements to provide adaptation an holding of a non-contact voltage tester 10 in a lightbulb socket 30. Adapter 40 is also shown here as a single unitary body, although it is envisioned that adapter 40 may comprise multiple components.

[0032] Body 42 defines an aperture 44. The aperture 44 may be surrounded by the body 42 around the entire perimeter of the aperture, as shown, or it has been envisioned that the body 42 may be non-continuous around the perimeter of the aperture 44. The body 42 defines a longitudinal direction as shown by a longitudinal axis 48. In the case of a circular body 42, the longitudinal axis 48 may be an axis 48 thru the center of the aperture 44. In the case of a non-circular body, or a non-continuous body, the longitudinal axis 48 may be thru a centroid of the aperture 44. Aperture 44 is configured to be disposable over one end 16 of a hand-held non-contact voltage tester 10 (see FIG. 3), or said another way the adapter 40 is configured to at least partially couple with a hand-held non-contact voltage tester 10 (FIG. 3).

[0033] Adapter 40 has a first engagement feature 50. The first engagement feature 50 is configured to at least partially couple with a hand-held non-contact voltage tester 10, similar to the tester in FIG. 1. Engagement feature 50 has a ledge 52. Ledge 52 extends radially inwardly from the body 42. Ledge 52 is substantially orthogonal to the longitudinal axis 48. Alternatively, ledge 52 may extend substantially transversely to the longitudinal aperture 44.

[0034] In this embodiment, the engagement feature 50 has an arm 54 that extends longitudinally from the body 42 ending with the ledge 52 extending transversely inwardly. The arms 54 allow for an elastic deformation to occur allowing for the engagement feature 50 to ride along a side of a tester 10 and engage with a catch (not shown) on the tester 10. The adapter 40, as shown here, has two opposing arms 54, 54b longitudinally extending from the body 42. Each arm 54, 54b ending with an inwardly projecting protrusion 56, 56b providing the transverse ledges 52, 52b. This is one embodiment that allows for at least one elastically deforming inwardly projecting protrusion 56, and as shown here is two opposing protrusions 56, 56b across the longitudinal axis 48. Yet another way to explain such an engagement feature 50 is a pair of transverse elastically deforming protrusions 56, 56b opposite each other configured to couple with opposing sides of a hand-held non-contact voltage tester 10.

[0035] In one embodiment, a second engagement feature 60 is configured to couple a hand-held non-contact voltage tester 10 with a lightbulb socket 30, such as those shown in FIG. 1. In another embodiment, the second engagement feature 60 is configured to be at least partially disposed within a lightbulb socket 30. And in yet another embodiment, the second engagement feature 60 is configured to couple with a female Edison screw 32.

[0036] The second engagement feature 60 extends outwardly from the body 42. The second engagement feature 60 is at least one protrusion 62 extending radially outwardly from the circular body 42. The second engagement feature 60 is at least one protrusion 62 configured to couple with a female Edison screw 32, such as that shown in FIG. 1. The second engagement feature 60, as shown here, is a male Edison screw 62b.

[0037] FIG. 3 is a partial side view of a non-contact voltage tester 110 with a lightbulb socket adapter 140a at least partially disposed over one end 116 of the tester 110. FIG. 4 is a partial side view of the same non-contact voltage tester 110 from FIG. 3, with a removable lightbulb socket adapter 140b removed from the one end 116 of the tester 110. FIG. 5 is a partial side view of the non-contact voltage tester 110 of FIGS. 3 and 4, with a lightbulb socket adapter 140c at least partially disposed over the one end 116 of the tester 110 and coupled with a lightbulb socket 130. The adapters 140a, 140b, 140c are configured to be at least partially disposable over a hand-held non-contact voltage tester 110. The adapters 140a, 140b, 140c are configured to couple with substantially parallel opposing sides 120a, 120b of a hand-held non-contact voltage tester 110. For example, many hand-held non-contact voltage testers 110 have a pen clip 121, as shown in FIG. 5. If the pen clip 121 side represents a top side, then the substantially parallel opposing sides 120a, 120b could be the left and right sides of the tester 110.

[0038] It is envisioned, that a hand-held non-contact voltage tester 110, such as that shown in FIG. 3, has an adapter 140a that is formed in as part of the end 116 of the tester 110 and is not removable. Of course in this embodiment there would be no need for a first engagement feature 50 as it be integral.

[0039] FIG. 6 shows a perspective view of another embodiment of a lightbulb socket adapter 240 for a hand-held non-contact voltage tester 10, 110, similar to the ones shown in FIGS. 1, 3, 4, and 5. FIG. 7 shows a diagrammatic cross-sectional illustration of the lightbulb socket adapter 240 of FIG. 6 being inserted into a lightbulb socket 230 with a female Edison screw 232. This adapter 240 is configured to be held in a lightbulb socket 230

[0040] Referring back to FIG. 6, adapter 240 has a body 242, and as shown here may be a substantially circular body 242. Substantially, as used here, means that it does not have to be perfectly circular, rather that it is circular, but could be ovular or any shape that can provide a structural member for the further needed elements to provide adaptation an holding of a non-contact voltage tester 10, 110 in a lightbulb socket 30, 130, 230.

[0041] Body 242 defines an aperture 244. The aperture 244 may be surrounded by the body 242 around the entire perimeter of the aperture, as shown, or it has been envisioned that the body 242 may be non-continuous around the perimeter of the aperture 244. The body 242 defines a longitudinal direction as shown by a longitudinal axis 248. In the case of a circular body 242, the longitudinal axis 248 may be an axis thru the center of the aperture 248. In the case of a non-circular body, or a non-continuous body, the longitudinal axis 248 may be thru a centroid of the aperture 244. Aperture 244 is configured to be disposable over one end 16, 116 of a hand-held non-contact voltage tester 10, 110 (see other Figs), or said another way the adapter 240 is configured to at least partially couple with a hand-held non-contact voltage tester 10, 110.

[0042] Adapter 240 has a first engagement feature 250. The first engagement feature 250 is configured to at least partially couple with a hand-held non-contact voltage tester 10, 110. Engagement feature 250 may have an arm 254 that extends longitudinally from the body 242. The arm 254 may allow for an elastic deformation to occur allowing for the engagement feature 250 to ride along a side of a tester 10, 110 and aid in the orientation of adapter 240 on the tester 10, 110.

[0043] In this embodiment, a second engagement feature 260 is configured to couple a hand-held non-contact voltage tester 10, 110 with a lightbulb socket 30, 230 such as those shown in other Figures. The second engagement feature 260 extends outwardly from the body 242. The second engagement feature 260 is at least one protrusion 262 extending radially outwardly from the circular body 242. The second engagement feature 260 is at least one protrusion 262 configured to couple with a female Edison screw 232, such as that shown in FIG. 7. The second engagement feature 260 is at least one elastically deforming outwardly projecting protrusion 262. The second engagement feature 260 may be two opposing protrusions 262, 262b across the longitudinal axis, or, as shown here, may be two pair of opposing protrusions 262, 262b, 262c, 262d across the longitudinal axis 248.

[0044] Protrusion 262 is at the end of limb 264. Each protrusion 262b, 262c, 262d may be located at a respective end of each Limb 264b, 264c, 264d. Each limb may be formed by slotting the body 242. The design of slotted sections of the body 242 provide for elastically deformable limbs 264, 264b, 264c, 264d. Or said another way, the protrusions 262, 262b, 262c, 262d may be referred to as elastically deformable.

[0045] Referring now to FIG. 7, as the adaptor 240 is inserted into the lightbulb socket 230, the elastically deformable protrusions 262, 262b, 262c will contact the female Edison screw 232 crests, allowing for the protrusions to elastically deform radially inwardly as the protrusions 262, 262b, 262c fall into the roots of the screw and the adapter 240 clicks down into the socket 230. The limb 264 springs the protrusion 262 back into the crest of the screw 232 and holds the adapter 240 within the socket 230. The adapter 240 may also be screwed in and out of position, but the slotted limbs 264 allow for quick insertion and engagement with the female Edison screw 232.

[0046] Adapter 242 may be made from a single unitary body with the slots forming the limbs 264 running longitudinally along the body 242 more than half of the longitudinal length of the body 242. Protrusions 262 may be straight, tapered, or triangular to match the pitch, slope, or thread angle of the screw 262. A set of three adaptors with differing radii of each body 242, and differing engagement protrusions 262 for the pitch, slope, depth, or thread angle may be employed for the female Edison screws of the candelabra, standard, and mogul (Goliath ES) lightbulb sockets.

[0047] While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the disclosed apparatus and method. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure as claimed. The features of various implementing embodiments may be combined to form further embodiments of the disclosed concepts.
