Claim 3

A foot control for power-operated equipment having reversible power-driven functions, comprising a housing adapted to rest upon a floor surface, said housing having at least three actuating members spaced laterally from each other to define at least two adjacent operating stations with one of said actuating members being disposed and partially defining said two adjacent operating stations; each operating station being wide enough to receive at least the toe portion of an operator's foot between two of said actuating members; each actuating member being mounted upon said housing for lateral movement from a neutral position towards and away from the operating station adjacent thereto; spring means urging and normally maintaining said actuating members in their neutral positions; an electrical switching means operatively associated with the actuating members of each of said stations for activating a reversible power function of said power-operated equipment connected to said foot control when such actuating member is urged by an operator's foot in a lateral direction away from the station receiving the toe portion of such foot; the reversible power function associated with each of said stations being different with said one actuating member disposed between said two adjacent operating stations being operatively associated with a pair of said switching means for activating each of said different power functions depending on the direction of lateral movement of said one actuating member.

Claim 4

A foot control for power-operated equipment having reversible power-driven functions, comprising a housing adapted to rest upon a floor surface, said housing having at least three actuating members spaced laterally from each other to define at least two adjacent operating stations with one of said actuating members being disposed and partially defining said two adjacent operating stations; each operating station being wide enough to receive at least the toe portion of an operator's foot between two of said actuating members; each actuating member being mounted upon said housing for lateral movement from a neutral position towards and away from the operating station adjacent thereto; spring means urging and normally maintaining said actuating members in their neutral positions; an electrical switching means operatively associated with the actuating members of each of said stations for activating a reversible power function of said power-operated equipment connected to said foot control when such actuating member is urged by an operator's foot in a lateral direction away from the station receiving the toe portion of such foot; the reversible power function associated with each of said stations being different with said one actuating member disposed between said two adjacent operating stations being operatively associated with a pair of said switching means for activating each of said different power functions depending on the direction of lateral movement of said one actuating member.

Claim 5

The foot control of claim 2 in which said housing has horizontally elongated top, front, and rear walls; said actuating members extending in directions between said front and rear walls and being pivotally supported upon said top wall.

Claim 6

The foot control of claim 3 in which each of said actuating members is elongated in a direction extending forwardly and rearwardly with respect to said housing.

Claim 7

The foot control of claim 2 in which the width of said station falls within the range of about 3 to 8 inches.

Claim 8

The foot control of claim 5 in which the width of said station falls within the range of about 4 to 6 inches.

Claim 9

A foot control assembly for power-operated equipment having a plurality of reversible power-driven functions, comprising a generally flat housing having laterally elongated top and rear walls and being adapted to rest upon a floor surface; said top wall being planar and sloping gradually upwardly and rearwardly; at least three actuating members mounted upon said top wall and spaced laterally from each other to define at least two operating stations therebetween; each station being bordered along its sides by a pair of said actuating members and being wide enough to receive at least the toe portion of an operator's foot between said pair of members; each member being mounted upon said top wall for lateral movement from a neutral position towards and away from each operating station immediately adjacent thereto; spring means urging and normally maintaining said members in their neutral positions; and electrical switching means operatively associated with each member for activating a reversible power function of said power-operated equipment connected to said foot control assembly when such member is urged laterally by an operator's foot in a direction away from the station receiving the toe portion of such foot; each of said stations being associated with a different power function with each actuating member disposed between two adjacent stations being operatively associated with a pair of said electrical switching means for activating the different power functions of said two adjacent stations depending on the direction of lateral movement of such actuating member.

Claim 10

A foot control assembly for power-operated equipment having a plurality of reversible power-driven functions, comprising a generally flat housing having laterally elongated top and rear walls and being adapted to rest upon a floor surface; said top wall being planar and sloping gradually upwardly and rearwardly; at least three actuating members mounted upon said top wall and spaced laterally from each other to define at least two operating stations therebetween; each station being bordered along its sides by a pair of said actuating members and being wide enough to receive at least the toe portion of an operator's foot between said pair of members; each member being mounted upon said top wall for lateral movement from a neutral position towards and away from each operating station immediately adjacent thereto; spring means urging and normally maintaining said members in their neutral positions; and electrical switching means operatively associated with each member for activating a reversible power function of said power-operated equipment connected to said foot control assembly when such member is urged laterally by an operator's foot in a direction away from the station receiving the toe portion of such foot; each of said stations being associated with a different power function with each actuating member disposed between two adjacent stations being operatively associated with a pair of said electrical switching means for activating the different power functions of said two adjacent stations depending on the direction of lateral movement of such actuating member.
