Insect killing device with removable electrically conductive grid

Claim 2

In an insect killing device of the type having an electrically powered light source surrounded by an electrically conductive grid, the said light source and grid being enclosed within a housing having a side wall surrounding said grid, said side wall being closed at its upper end by a top and defining an open port at its lower end, said light source and said grid being energizable by an electric AC power source external to said housing via electric circuit components located in said housing, said side wall having an array of openings through which insects attracted by said energized light source may pass to come into contact with and be electrocuted by said energized grid, the improvement comprising: said grid being supported on a dielectric carrier and being separably connected to said electric circuit components, said carrier having a dielectric bottom portion dimensioned and arranged to enter said port and to block access to said grid through said port when said grid is energized, said grid and said carrier being removable as a unit from said housing through said port, with the arrangement of said grid and the bottom portion of said carrier in relation to that of said side wall and said port being such that said grid is disconnected from said circuit components and thus de-energized prior to said port being unblocked by removal of said bottom portion therefrom.

Claim 3

The device of claim 1 wherein said carrier is detachably secured to said side wall.

Claim 5

The device of claim 1 wherein said housing is internally subdivided by a shelf into upper and lower chambers, said electric circuit components being located in said upper chamber and said grid, carrier and light source being located in said lower chamber.

Claim 6

The device of claim 4 further comprising means extending through said shelf for separably connecting said grid to said electric circuit components.

Claim 7

The device of claim 1 wherein said light source is separably connected to said electric circuit components, said light source being removable from said housing through said port following removal of said grid and carrier.

Claim 8

The device of claim 4 wherein said light source is separably connected to said electric circuit components by means of a socket located on the underside of said shelf, said carrier being detachably secured to said side wall and being engageable with said light source to maintain the same in engagement with said socket.

Claim 9

In an insect killing device of the type having an electrically powered light source surrounded by an electrically conductive grid, the said light source and grid being enclosed within a housing having a side wall surrounding and spaced outwardly from said grid, said side wall being closed at its upper end by an impervious top and defining an open port at its lower end, said light source and said grid being energizable by an electric AC power source external to said housing via electric circuit components located in said housing, said side wall having an array of openings through which insects attracted by said enrgized light source may pass to come into contact with and be electrocuted by said energized grid, the improvement comprising: said grid being supported on a dielectric carrier, said carrier having a dieletric bottom portion dimensioned and arranged to enter said port and to block access to said grid through said port when said grid is energized, a shelf internally subdividing said housing into upper and lower chambers, said electric circuit components being located in said upper chamber and said grid, carrier and light source being located in said lower chamber, first means extending through said shelf for separably connecting said grid to said electric circuit components, second means for separably connecting said light source to said electric circuit components, said grid and carrier being removable as a unit from said housing through said port, with the arrangement of said grid and the bottom portion of said carrier in relation to that of said side wall and said port being such that said grid is separated from said circuit components and thus is de-energized prior to said port being unblocked by removal of said bottom portion therefrom, said light source also being removable from said housing through said port following removal of said grid and carrier.

Claim 10

In an insect killing device of the type having an electrically powered light source surrounded by an electrically conductive grid, the said light source and grid being enclosed within a housing having a side wall surrounding and spaced outwardly from said grid, said side wall being closed at its upper end by an impervious top and defining an open port at its lower end, said light source and said grid being energizable by an electric AC power source external to said housing via electric circuit components located in said housing, said side wall having an array of openings through which insects attracted by said enrgized light source may pass to come into contact with and be electrocuted by said energized grid, the improvement comprising: said grid being supported on a dielectric carrier, said carrier having a dieletric bottom portion dimensioned and arranged to enter said port and to block access to said grid through said port when said grid is energized, a shelf internally subdividing said housing into upper and lower chambers, said electric circuit components being located in said upper chamber and said grid, carrier and light source being located in said lower chamber, first means extending through said shelf for separably connecting said grid to said electric circuit components, second means for separably connecting said light source to said electric circuit components, said grid and carrier being removable as a unit from said housing through said port, with the arrangement of said grid and the bottom portion of said carrier in relation to that of said side wall and said port being such that said grid is separated from said circuit components and thus is de-energized prior to said port being unblocked by removal of said bottom portion therefrom, said light source also being removable from said housing through said port following removal of said grid and carrier.
