Abstract

A cordless lawn mower 1 is powered by direct current re-chargeable batteries. The mower may be controlled from a remote controller (Fig.6).

Description

-I- CORDLESS ELECTRIC GRASS LAWN MOWER.
2331908 This invention relates to a cordless grass lawn mower.
Standard electric grass lawn mowers are well knowt. However there safty and effectivness are restricted by the nweessity of power supply transmitted by means of an electric cable between power scource and the electric grass lawn mower.
According to.the present invention there are no electric cables required or incorporated for transmission,from 240 volts mains supply.
Energy for the cordless electric grass lawn mower is derived from X.R. rechargeable batteries.
This necessitates a motor of direct consumption current, as apposed to the existing alternating current provided by the mains supply.
A remote controll mechanism is provided where required.
A specific embodyment of the invention will now be described by way of example with reference to the accompanying drawings in which:- Figure 1 shbib in perspective the cordless electric grass lawn mower.
Figure 2 illustrares the X.R. or similar rechargeable batteries.
Figure 3 illustrates the battery charger.
Figure 4 illustrates the Brittish Standard domest power socket.
Figure 5 illustrates the battery charger in position adjacant to the power socket.
Figure 6 standard remote controller.
Referring to the drawing in order to produce a cordless electric grass lawn mower the A.C. motor 1 has to be replaced by a D.C. motor 2 which is powered by X.R. or similar batteries 4.
1 The adaption of an D.C. moter reguires batteries as illustrated in figure 2 containing 14'4.to 28#8. volts in series as required.
The above batteries require recharging from a specified battery charger as illustrated in figure 3.
The battery charger is housed close to the power plug 4.
The wall mounting unit is affixed and incorporated within the existing 240 volts. british Standard Installation as in figure 5.
C LA IMS.
A cordless electric grass lawn mower as claimed requires no electric cable for power transmission and is powered by direct current from batteries.
