20120317949 | ELECTRIC LAWN MOWERS - An electric lawn mower may include a switch assembly including a first switch, a second switch and a main switch. When the main switch is turned on an electric motor is started. The first and second switch may include first and second actuators, respectively. When the switch assembly is operated according to a proper operation sequence, the first actuator and the second actuator may interact with each other to activate the main switch, and when the switch is operated according to an improper operation sequence, the first actuator and the second actuator may not interact with each other, so that the main switch is not activated. | 12-20-2012 |
20130212995 | RIDING MOWER - A riding mower includes two (left and right) mower blades, a mower deck, and two motors for rotating the mower blades. The mower blades are provided adjacent to each other, and one of the two mower blades is disposed obliquely in front of the other mower blade. In a plan view, the left mower blade is rotated clockwise and the right mower blade is rotated counterclockwise. A combined air flow is generated in the mower deck, and mowed grass is discharged to the outside of the mower deck together with the combined air flow. The rotational speed of the forward mower blade is set higher than the rearward mower blade. The speed of the air flow generated by the forward mower blade is higher than the rearward mower blade. The combined air flow is generated and the mowed grass is discharged rearward of the mower deck. | 08-22-2013 |
20130291505 | Isolator Switch Assembly - An isolator switch assembly, especially an isolator switch and key assembly for a powered apparatus, such as a lawncare product, for example a lawnmower, includes a key, a keyway and an electrical switch positioned adjacent the keyway. The assembly is arranged to provide a first configuration in which the key is insertable into and removable from the keyway and the switch is open and a second configuration in which the key bears against an actuator surface of the switch to close the switch. In one embodiment, the assembly is arranged to provide a third configuration in which the switch is not actuated and the key is not removable from the keyway and is biased into a predetermined rotational position intermediate the first and second configurations. In a further embodiment, the assembly is provided with an over-torque or over-rotation prevention means. | 11-07-2013 |
20140102063 | LAWNMOWER WITH OPERATION PROTECTION AND SAFETY SWITCH MECHANISM THEREOF - A lawnmower with operation protection and a safety switch mechanism. The safety switch mechanism include: an inner pipe and a pipe sleeve slidably connected with and enclosing the inner pipe, a safety switch with a contact tab mounted inside the pipe sleeve, a trigger configured to trigger the safety switch by contacting the contact tab when the inner pipe slides, and an elastomer configured to drive the trigger to keep from contacting with the contact tab. All of the safety switch, the trigger and the elastomer are arranged on the same side of the inner pipe. The safety switch mechanism functions to disable the motor upon accidental proximity of the operator to the cutter body to thereby lower the possibility of an accident. | 04-17-2014 |
20140102064 | LAWNCARE APPARATUS - A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved. | 04-17-2014 |
20140190141 | HANDLE CONTROL ARRANGEMENT OF A WALK-BEHIND LAWN MOWER - A walk-behind lawn mower comprising a body with an engine driving a cutting blade, and a handle assembly which is pivotably connected to the body. The lawn mower furthermore comprises a handle control arrangement for controlling pivotal movement of the handle assembly relative to the bod, between a working position and a pivoted position. The handle control arrangement comprises a locking member, selectively displaceable between an open state in which the locking member allows pivotal movement of the handle assembly from the working position to the pivoted position, and a locked state in which the locking member inhibits pivotal movement of the handle assembly from the working position to the pivoted position. The handle control arrangement also comprises an actuating member operatively connected to the locking member and controlling the state of the locking member. The actuating member is also arranged to control activation and deactivation of a device arranged to inhibit rotation of the cutting blade of the walk-behind lawn mower. | 07-10-2014 |
