ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a power driven gardening device, more particularly to a foldable power driven gardening device with a handle member which is foldable relative to a support member of the gardening device.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional power driven mower is shown to include a motor
101
with an output shaft (not shown), and a coupling shaft (not shown) which is received in a tubular sleeve
102
and which is connected to the output shaft at one end thereof, and which is connected to a cutter
103
at the other end thereof. A support frame
2
is disposed to support the motor
101
, and is provided with a pair of wheels
201
. A handle
3
is mounted detachably on, and extends upwardly and rearwardly from the support frame

SUMMARY OF THE INVENTION
The object of the present invention is to provide a foldable power driven gardening device having a handle member which is foldable to facilitate storing of the same.
According to this invention, the foldable power driven gardening device includes a wheel axle which extends in a first axis, and which has two ends that are respectively provided with a pair of wheels thereon. A support member includes a lower portion which is secured relative to the wheel axle between the wheels, and an upper portion which extends upwardly and in a first direction transverse to the first axis from the lower portion. A motor has an output shaft and is supported on the upper portion of the support member. A coupling shaft is mounted to be rotatable relative to the support member, and has a first rear end portion which is coupled with and which is driven by the output shaft, and a first front end portion which extends from the first rear end portion in a second direction substantially transverse to both the first axis and the first direction to terminate at a coupling end. A sleeve mount member is sleeved on the first rear end portion to permit rotation of the first rear end portion relative thereto, and has a distal end portion which is connected securely to the support member, and a proximate end portion opposite to the distal end portion in the second direction. A tool member is mounted on and is driven by the coupling end. A handle member has a second front end portion which is secured to be pivotable relative to the proximate end portion of the sleeve mount member about a second axis parallel to the first axis, and a second rear end portion which extends upwardly and rearwardly from the second front end portion and which terminates at a handgrip end that extends rearwardly of the wheels. As such, the second rear end portion is turnable about the second axis between an operating position, where the handgrip end is placed rearwardly of the wheels, and a folded position, where the handgrip end is placed forwardly of the wheels and is proximate to the coupling end of the coupling shaft. A retaining member is disposed to retain the upper portion of the support member relative to the second rear end portion of the handle member when the second rear end portion is in the operating position.
