Abstract

Ergonomic plow control system has a housing which can be mounted to a component in a cab of a vehicle; and a switch pad having control keys, the pad mounted in the housing such that the keys are readily accessible to an operator of the vehicle during plowing operation such as shifting and/or steering. A securing member may be attached to the housing away from the pad and keys for mounting the housing to the cab component. The switch pad may include an arrangement for control of a straight plow and/or of a V-plow having a central element divided into a plurality of independently actuatable switches as for controlling orientation of the plow; and at least one laterally disposed switch set for controlling vertical adjustment of the plow. Another switch set as for controlling “on-off” of the plow may be provided. The housing may be resilient, making for increased comfort especially in long-term operation. Also, the control system can be wireless and remote.

Claims

1. An ergonomic plow control system comprising a housing capable of being mounted to a component in a cab of a vehicle;

and a switch pad having control keys, said pad mounted in a face of the housing such that said keys are readily accessible to an operator of the vehicle while shifting and/or steering during plowing, wherein;

a securing member is attached to the housing away from said pad and keys for mounting the housing to said component;

the housing is detachable;

the switch pad includes an arrangement for control of a straight plow and/or a V-plow, which has, mounted in said face a central element divided into a plurality of independently actuatable switches for controlling orientation of the plow;

at least one laterally disposed switch set for controlling vertical adjustment of the plow; and

another switch set for controlling “

on-off”

of the plow;

the switch pad arrangement has a resilient housing, making for increased comfort in long-term operation; and

the housing, switch pad, and securing member are assembled to be compact such that the same can be stored in a glove box of the vehicle.

2. The ergonomic plow control system of claim 1, wherein the housing includes an underside that has a suitably shaped mounting channel through which a steering wheel rim or gearshift lever can pass within confines of the housing to provide for mounting.

3. The ergonomic plow control system of claim 1, wherein the housing is made to be cannulated to form an interior mounting channel and the securing member so that a gear shift lover with a knob thereof removed can slip through the channel to provide for mounting.

4. The ergonomic plow control system of claim 1, wherein the central element has two or four independently actuatable key pad switches for controlling orientation of the plow;

a first laterally disposed switch set having two key pad switches for controlling vertical adjustment of the plow; and

a second laterally disposed switch set opposing the first laterally disposed switch set and having two key pad switches for controlling “

on-off”

of the plow.

5. The ergonomic plow control system of claim 2, wherein the central element has two or four independently actuatable key pad switches for controlling orientation of the plow;

a first laterally disposed switch set having two key pad switches for controlling vertical adjustment of the plow; and

a second laterally disposed switch set opposing the first laterally disposed switch set and having two key pad switches for controlling “

on-off”

of the plow.

6. The ergonomic plow control system of claim 3, wherein the central element has two or four independently actuatable key pad switches for controlling orientation of the plow;

a first laterally disposed switch set having two key pad switches for controlling vertical adjustment of the plow; and

a second laterally disposed switch set opposing the first laterally disposed switch set and having two key pad switches for controlling “

on-off”

of the plow.

7. The ergonomic plow control system of claim 2, which is wireless and remote.

8. The ergonomic plow control system of claim 3, which is wireless and remote.

9. The ergonomic plow control system of claim 4, which is wireless and remote.

10. The ergonomic plow control system of claim 5, which is wireless and remote.

11. The ergonomic plow control system of claim 6, which is wireless and remote.

12. The ergonomic plow control system of claim 1, wherein the resilient housing is made of a foamed closed cell plastic.

15. The ergonomic plow control system of claim 1, which is wireless and remote.

13. An ergonomic plow control system, which comprises:

a housing capable of being mounted to a component in a cab of a vehicle, wherein the housing is detachable and mounts through a subsystem selected from the group consisting of

(i) an underside to the housing that has a suitably shaped mounting channel through which a steering wheel rim or gearshift lever can pass within confines of the housing for mounting, and a securing member includes a mounting strap; and

(ii) a cannulation to the housing that forms an interior mounting channel and the securing member so that a gear shift lever with a knob thereof removed can slip through the channel to provide for mounting; and

an unobtrusive control system including a switch pad having control keys, the switch pad mounted in the housing such that the control keys are readily accessible to an operator of the vehicle while shifting and/or steering during plowing, and including an arrangement for control of a straight plow and/or a V-plow, which has;

a central element divided into a plurality of independently actuatable key pad switches for controlling orientation of the plow;

a first laterally disposed switch set having key pad switches for controlling vertical adjustment of the plow; and

a second laterally disposed switch set opposing the the first laterally disposed switch set, and having key pad switches for controlling “

on-off”

of the plow, said system having a minimum profile.

14. The ergonomic plow control system of claim 13, wherein at least one of the following two limitations (A, B) is present:

(A) the suitably shaped mounting channel of the housing subsystem (i) is generally semicylindrical;

(B) the central element has two or four independently actuatable key pad switches for controlling orientation of the plow;

the first laterally disposed switch set has two key pad switches for controlling vertical adjustment of the plow;

the second laterally disposed switch set has two key pad switches for controlling “

on-off”

of the plow.
