Abstract
Abstract A hand held spotlight includes a sealed beam enclosure together with one or more detachable handles. The detachable handles each include a latching mechanism capable of translating a magnet between a first position and a second position. A magnetically-actuated switch within the enclosure is used to turn off and on the light circuit. The handle is detachably mounted on the enclosure in a particular position so that the magnetically-actuated switch within the enclosure may be opened and closed by the magnet in the handle. In the preferred embodiments, a single enclosure may be utilized with either a pistol-style grip or a lantern-style grip. The ability to form the beam enclosure without penetrations is particularly useful in providing watertight and explosion-proof spotlights.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A lighting apparatus: a first detachable handle including actuable means for moving a magnet between a first position and a second position; and an enclosure physically separate from the handle and including external means for coupling the handle; an internal magnetic switch located proximate the coupling means so that said switch is actuated as the magnet in the handle moves from the first to the second position; and internal means defining a circuit electrically connected to said magnetic switch, said enclosure remaining sealed when said handle is removed.
Claim 2
Dependent Claim
88 words
A lighting apparatus: a first detachable handle including actuable means for moving a magnet between a first position and a second position; and an enclosure physically separate from the handle and including external means for coupling the handle; an internal magnetic switch located proximate the coupling means so that said switch is actuated as the magnet in the handle moves from the first to the second position; and internal means defining a circuit electrically connected to said magnetic switch, said enclosure remaining sealed when said handle is removed.
Claim 3
Dependent Claim
48 words
An apparatus as in claim 1, further comprising a second handle including actuable means for moving a magnet between a first position and a second position, said first and second handles both being capable of detachable coupling to the coupling means but having different configurations from one another.
Claim 4
Dependent Claim
13 words
an apparatus as in claim 1, wherein the circuit is a light circuit.
Claim 5
Dependent Claim
11 words
An apparatus as in claim 1, wherein the circuit includes batteries.
Claim 6
Dependent Claim
16 words
An apparatus as in claim 1, wherein the enclosure is sealable against the entry of water.
Claim 7
Dependent Claim
113 words
An electric lantern having a detachable handle, said lantern comprising: a first handle including a manually actuated latching mechanism capable of selectively holding a magnet in a first or a second position, and a coupling member; and a beam enclosure physically separate from the handle and including an external coupling member capable of detachably mating with the coupling member on the handle, an internal magnetic switch located proximate the external coupling member so that the switch is closed when the magnet in the handle is in the first position, a battery-powered light circuit electrically connected to the switch, and reflector and lens means, said beam enclosure remaining sealed when said handle is removed.
Claim 8
Dependent Claim
113 words
An electric lantern having a detachable handle, said lantern comprising: a first handle including a manually actuated latching mechanism capable of selectively holding a magnet in a first or a second position, and a coupling member; and a beam enclosure physically separate from the handle and including an external coupling member capable of detachably mating with the coupling member on the handle, an internal magnetic switch located proximate the external coupling member so that the switch is closed when the magnet in the handle is in the first position, a battery-powered light circuit electrically connected to the switch, and reflector and lens means, said beam enclosure remaining sealed when said handle is removed.
Claim 9
Dependent Claim
59 words
An electric lantern as in claimm 6, further comprising a second detachable handle including a manually actuated latching mechanism capable of selectively holding a magnet in a first or a second position and a coupling member, said first and second handles having different configurations but each being capable of attachment to the external coupling member on the beam enclosure.
Claim 10
Dependent Claim
23 words
An electric lantern as in claim 7, wherein one of the handles is a pistol-style grip and the other is a lantern-style grip.
