Articulating handle for a walk-behind mower
View Patent ↗A walk-behind greensmower includes an operator presence control for selectively determining when power from a source is delivered to an output. The operator presence control includes a handle, a bale coupled to the handle, a control arm and an electromagnet. The bale is moveable between an engaged position and a disengaged position. The control arm is moveable between a neutral position and a drive position where the control arm causes delivery of power from the source to the output when in the drive position. The electromagnet is selectively energizable in response to the position of the bale such that the control arm is retained in the drive position when the bale is in the engaged position.
1. An operator presence control for selectively determining when power from a source is delivered to an output, the operator presence control comprising:
a handle;
a bale coupled to the handle and moveable between an engaged position and a disengaged position;
a control arm moveable between a neutral position and a drive position, the control arm adapted to cause delivery of power from the source to the output when in the drive position and interrupt power delivery when in the neutral position; and
an electromagnet selectively energizable in response to the position of the bale, the control arm being electro-magnetically retained in the drive position while the bale is in the engaged position.
2. The operator presence control of claim 1 wherein the control arm is released from the drive position and biased toward the neutral position when the electromagnet is de-energized due to the bale being in the disengaged position.
3. The operator presence control of claim 1 further including a rectifier for converting an alternating current to an direct current, the direct current being selectively supplied to the electromagnet.
4. The operator presence control of claim 1 further including a link coupled to the control arm for selectively tensioning a cable adapted to cause delivery of power from the source to the output.
5. The operator presence control of claim 1 wherein the control arm is moveable to a brake position and wherein the control arm is adapted to cause application of a brake.
6. The operator presence control of claim 5 further including a link coupled to the control arm for selectively tensioning a cable adapted to cause application of the brake.
