Apparatus for controlling discharge from a mower
View Patent ↗Assemblies allowing a repositionable discharge deflector to be added to a mower with a discharge chute are described. These assemblies include a base, a swing bracket, a discharge deflector, a motor, and a switch. The base is attached to the mower, and the motor is attached to the base and includes a rotating output shaft. The swing bracket is rotationally attached to the base and is rotationally coupled to the rotating output shaft of the motor. The discharge deflector is attached to the swing bracket and positionable via rotation of the rotating output shaft so as to at least partially block the discharge chute of the mower. The switch is in electrical communication with the motor and is able to cause the motor to rotate the rotating output shaft. The assemblies allow a user to modify the trajectory of mown material discharged from the discharge chute of the mower with a push of the switch.
1. An apparatus comprising:
a mower comprising a discharge chute for discharging mown material;
a base attached to the mower;
a motor attached to the base and comprising a rotating output shaft, which rotates about a rotational axis;
a swing bracket rotationally attached to the base and rotationally coupled to the rotating output shaft;
a discharge deflector attached to the swing bracket and positionable via rotation of the rotating output shaft so as to at least partially block the discharge chute; and
a switch in electrical communication with the motor and operative to cause the motor to rotate the rotating output shaft;
wherein the rotational axis passes through the base and the swing bracket.
2. The apparatus of claim 1 , further comprising a plurality of magnets attaching the base to the mower.
3. The apparatus of claim 1 , wherein the base comprises a u-shaped bracket defining a middle base region spanning between a left base region and a right base region that are oriented substantially normal to the middle base region.
4. The apparatus of claim 3 , wherein at least part of the swing bracket is positioned between the left base region and the right base region.
5. The apparatus of claim 1 , wherein the motor comprises a DC motor.
6. The apparatus of claim 1 , wherein the motor comprises a worm drive gear.
7. The apparatus of claim 1 , wherein a portion of the rotating output shaft has a non-circular cross-section.
8. The apparatus of claim 1 , wherein the swing bracket comprises a u-shaped bracket defining a middle bracket region spanning between a left bracket region and a right bracket region that are oriented substantially normal to the middle bracket region.
9. The apparatus of claim 8 , wherein the discharge deflector is attached to the middle bracket region.
10. The apparatus of claim 8 , wherein
the rotational axis passes through the left bracket region and the right bracket region.
11. The apparatus of claim 1 , wherein:
the swing bracket defines a hole; and
the rotating output shaft passes through the hole.
12. The apparatus of claim 11 , wherein the hole is non-circular.
13. The apparatus of claim 1 , wherein:
the mower comprises a battery; and
the switch is electrically connected to the battery.
14. The apparatus of claim 1 , wherein the switch comprises a double-pole, double-throw switch wired as a reversing switch for the motor.
15. The apparatus of claim 1 , wherein the switch comprises a rocker switch.
16. The apparatus of claim 1 , wherein:
the mower further comprises a control; and
the switch is attached to the control.
17. The apparatus of claim 16 , further comprising a clamp attaching the switch to the control.
18. The apparatus of claim 16 , wherein the control is a steering lever.
19. The apparatus of claim 1 , further comprising a retractable spring plunger attached to the base and operative to take on a retracted state and an extended state, wherein:
the retractable spring plunger interferes with movement of the swing bracket with the retractable spring plunger in its extended state; and
the retractable spring plunger does not interfere with movement of the swing bracket with the retractable spring plunger in its retracted state.
20. The apparatus of claim 1 , further comprising a plunger solenoid attached to the base and operative to take on a retracted state and an extended state, wherein:
the plunger solenoid interferes with movement of the swing bracket with the plunger solenoid in its extended state; and
the plunger solenoid does not interfere with movement of the swing bracket with the plunger solenoid in its retracted state.
