Enclosure for machine control panel

Claim 2

An enclosure for a machine control panel, the enclosure comprising: A) an enclosure body having an outer periphery portion, a first enclosure side, and a second enclosure side; B) a heat sink formed along the second enclosure side; and C) a fixed cover plate having at least two edges, the at least two edges being joined by a free edge, wherein the cover plate is formed along the second enclosure side between the heat sink and the outer periphery portion, said cover plate having lip means along the at least two edges, said lip means for directing moisture away from the enclosure body, said free edge being located away from the second enclosure side.

Claim 3

The enclosure as claimed in claim 1 wherein the enclosure is unitary.

Claim 4

The enclosure as claimed in claim 1 wherein the heat sink extends longitudinally along the second enclosure side the enclosure body having a window and a slot.

Claim 5

Claim 6

The enclosure as claimed in claim 1, the enclosure further comprising a support shield attached to the second enclosure side, the support shield comprising: a first wall, a second wall, a third wall joining the first and second walls, the first and second walls each having an edge made integral with the heat sink, the first, second, and third walls, heat sink and second enclosure side defining a shield chamber.

Claim 7

The enclosure as claimed in claim 5, the enclosure further comprising at least one support pillar located between the first and second walls adjacent the heat sink.

Claim 8

The enclosure as claimed in claim 1 wherein the heat sink is made integral with the cover plate.

Claim 9

The enclosure as claimed in claim 6 wherein the at least one support pillar is made integral with the heat sink.

Claim 10

The enclosure as claimed in claim 1 wherein the outer periphery defines a recess, said outer periphery having a first edge and a second edge and a bezel along the first and second edges.

Claim 11

The enclosure as claimed in claim 5, the enclosure further comprising tangs adjacent the first, second, and third walls.

Claim 12

The enclosure as claimed in claim 1 wherein the cover plate is substantially perpendicular to the enclosure body.

Claim 13

The enclosure as claimed in claim 1 wherein the heat sink is substantially perpendicular to the enclosure body.

Claim 14

A machine control panel assembly comprising; A) An enclosure for a machine control panel, the enclosure comprising: an enclosure body having a window and an outer periphery which defines a recess, a first enclosure side, and a second enclosure side; a heat sink along the second enclosure side; and a cover plate having at least two cover plate edges, wherein the cover plate is located between the heat sink and the outer periphery, said cover plate having means for directing fluid away from the enclosure, said means being provided along the at least two edges, the enclosure further comprising a support shield comprising a first wall, a second wall, and a third wall joining the first and second walls, the first and second walls having an edge made integral with the heat sink; and alignment tang members adjacent said walls; B) display means located in said enclosure window; C) a membrane switch located in the recess, said membrane switch having a membrane window which overlies said display means when the membrane switch is located in said recess; D) a circuit board supported by the first, second, and third walls of the support shield, said circuit board being electrically connected to the display means and membrane switch; and E) a back cover which encloses the circuit board and display means.

Claim 15

A machine control panel assembly comprising; A) An enclosure for a machine control panel, the enclosure comprising: an enclosure body having a window and an outer periphery which defines a recess, a first enclosure side, and a second enclosure side; a heat sink along the second enclosure side; and a cover plate having at least two cover plate edges, wherein the cover plate is located between the heat sink and the outer periphery, said cover plate having means for directing fluid away from the enclosure, said means being provided along the at least two edges, the enclosure further comprising a support shield comprising a first wall, a second wall, and a third wall joining the first and second walls, the first and second walls having an edge made integral with the heat sink; and alignment tang members adjacent said walls; B) display means located in said enclosure window; C) a membrane switch located in the recess, said membrane switch having a membrane window which overlies said display means when the membrane switch is located in said recess; D) a circuit board supported by the first, second, and third walls of the support shield, said circuit board being electrically connected to the display means and membrane switch; and E) a back cover which encloses the circuit board and display means.

Claim 16

The machine control panel assembly as claimed in claim 13 wherein the display means is a LCD display.

Claim 17

The machine control panel assembly as claimed in claim 13 wherein the circuit board includes at least one component that is thermally bonded to the heat sink.

Claim 18

The machine control panel as claimed in claim 13 wherein the back cover has a first cover side located between the first wall and the tangs adjacent thereto, a second cover side located between the second wall and tangs adjacent thereto, and a third cover side located between the third wall and the tangs.

Claim 19

The machine control panel as claimed in claim 11 wherein the cover plate is substantially perpendicular to the enclosure body.
