LAWN MOWER

Description

B02002U oooooe TITLE: LAWN MOWER OWNER: LAINO VINCENZO, Via Zanardi 19, 40131, Bologna. DESCRIPTION : ( SEE PHOTOGRAPHS ) THIS MODEL REFERS TO A LAWN MOWER FRONT, OF REDUCED SIZE AND WEIGHT, WHICH ALLOWS YOU TO EFFECT ARE A TRIM GRASS CUT NEARBY EDGES OF FLOWER BEDS, SIDEWALK, WALLS, UNDER BUSHES, PATHS ETC. OR EVEN IN OPEN FIELD, IN A SILENT, SIMPLE, CLEAN WAY AND SURE, FROM ANYONE. CURRENTLY TO MOW GARDEN GRASS THERE ARE TWO BASIC MACHINES AVAILABLE: THE LAWN MOWER (FRONT OR ROTATING BLADE) WITH COMBUSTION ENGINE, OR THE CORD-OPERATED OILER DECESPU WITH COMBUSTION OR ELECTRIC ENGINE. THE USE OF THE LAWN MOWER (GENERALLY ADOPTED FOR CUTTING GRASS ON LARGE SURFACES) DOES NOT ALLOW TO OBTAIN THE CUTTING THREAD OF SIDEWALK, EDGES, UNDER BUSHES AND IN GENERAL THE CUTTING IN SMALL OR DIFFICULT-ACCESS SPACES SUCH AS EXAMPLE OF PATH EDGES IN SMALL GARDENS, ETC. THE USE OF THE WIRE BRUSHCUTTER, ON THE OTHER HAND, ALTHOUGH IT ALLOWS ELIMINATING GRASS IN SMALL SPACES INVOLVES A SERIES OF INCONVENIENCES: FIRST OF ALL THE NEED TO ADOPTE A SERIES OF INDIVIDUAL PROTECTION MEASURES (CLOTHING, PROTECTIVE FACE MASK ETC.). THE PROJECTION OF DEBRIS (PLANTING FRAGMENTS, GRAVEL, TERRICC OR ETC.) AROUND MAKING IT NECESSARY AFTER THE CUTTING l N CLEANING AND TIDYING UP INTERVENTION. IN THE CASE OF A BRUSHCUTTER WITH A COMBUSTION ENGINE I KNOW DISADVANTAGES RELATED TO THIS TYPE OF MOTORIZATION ESPECIALLY IN THE CASE OF LONG INTERVALS OF USE: FUEL SUPPLY, STARTING, SPARK PLUGS IGNITION, NOISE AND ALL THE PROBLEMS THAT WHO HE USES THIS MACHINE WELL KNOWS. IN THE CASE OF ELECTRIC MOTORIZATION, THE NEED FOR HAVE A POWER SUPPLY POINT NEARBY AND IN ANY CASE OF A LONG PRC TO DRAG BEHIND WITH ITS INCONVENIENCES WELL KNOWN (SOCKETS, REDUCTIONS, ADAPTERS ETC.) NOT TO MENTION OF THE RISKS PRESENT IN ANY CASE WHEN OPERATION IS IN THE PRESENCE OF TENSION ELECTRICITY NETWORKS AND THE DAMAGES THAT INEVITABLY OCCUR THEY ARE AFFECTED BY ADJACENT FLOWERS AND PLANTS. THE MACHINE DESCRIBED HERE INTENDS TO OVERCOME THE INCONVENIENCES DESCRIBED THANKS TO HIS CONCEPT ORIGINAL.E. THE LAWN MOWER MODEL FOR WHICH THE PATENT IS APPLIED FOR CONSTA 31 A BASE, APPROPRIATELY SHAPED, IN MATERIAL PLASTIC, DIMENSIONS 310 mm WIDE, 200 mm DEEP DEPTH AND 5mm OF THICKNESS, TO WHICH A WHEEL IS FIXED BAND WIDE AND OF APPROPRIATE DIAMETER MOUNTED SYMMETPHICALLY IN POSITION SUCH AS TO ALLOW A EASY TRANSLATION ON THE GROUND AND A COMFORTABLE BALANCE SHEET? THE MACHINE'S MINUS. A BLADE HOLDER IS FIXED ON THE BASE, IN A FRONT POSITION, ALWAYS MADE OF PLASTIC MATERIAL, WHICH REPEATS THE SHAPE FRONT OF THE BASE ITSELF. A LONGITUDINAL MILLING ON THE LOWER FACE OF THE BLADE HOLDER IT ALLOWS TO CONTAIN THE FIXED LOWER BLADE AND THE MOVABLE UPPER BLADE OF THE WHICH ALSO CONSTITUTES THE SLIDING GUIDE OF THE EXTREMES AGO'. THE DISPOSAL THE ACTUAL CUTTING PLANT IS MADE UP OF A LAMA FIXED LOWER, EQUIPPED WITH SHAPE TEETH APPROX TRIANGULAR, IN QUENCHED AND HARDENED STEEL FROM A UPPER BLADE ALSO EQUIPPED WITH SHAPED TEETH ANALOGOUS, IN STAINLESS STEEL AND EQUIPPED WITH MOTORCYCLE ALTERNATIVE THAT LEAD IT TO COVER, BETWEEN THE OPPOSITE EXTREMES OF THE C :DRSA , THE TEETH OF THE BLADE UNDERLYING AND MAKING SO THE CUTTING GRASS THAT COMES BETWEEN THE TEETH OF THE FIXED BLADE. THE TEETH OF THE FIXED BLADE ARE SLIGHTLY LONGER THAN THOSE OF THE MOVING BLADE IN ORDER TO AVOID THAT, WHEN THE LAWN MOWER TOUCHS AN OBSTACLE, THE MOVING BLADE BE INTERESTED. THE ALTERNATE MOMENT OF THE UPPER BLADE IS MADE WITH AN OSCILLATING GLYPH DEVICE THAT MOVES A LEVER WITH AN INTERMEDIATE AXIS; ONE END OF THIS ÈVA HAS A RECESS THAT ENGAGES WITH A PIN SOLID AL TO THE MOVING BLADE, ON THE OTHER END IS THE SLOT IN WHICH THE ECCENTRIC PIN ENGAGES HAS BEEN MADE. THE MOTO ROTARY OF THE ECCENTRIC PIN HOLDER ELEMENT, IT IS PROVIDED FROM A DC GEAR MOTOR WITH SPEED 'A' OF THE OUTPUT SHAFT EQUAL TO APPROXIMATELY 850 RPM MINUTE FIRST. THE GEAR MOTOR UNIT IS FIXED BY MEANS OF SCREWS TO] AT THE BASE. THE LEVER PIN THAT TRANSFERS THE MOVEMENT TO THE UPPER BLADE IS INSERTED IN A BUSHING HOUSED IN THE BASE. THE' POWER TO THE GEAR MOTOR IS SUPPLIED BY A LEAD ACID BATTERY WITH A CAPACITY OF 4.5 Ah WITH VOLTAGE 12 VOLTS. THE BATTERY IS HOUSED BETWEEN THE GROUP ENGINE AND THE REAR END OF THE BASE; IT IS OF THE TYPE SIG] MAINTENANCE FREE AND WEIGHS APPROXIMATELY 1.4 Kg. ON THE SIDE A DEVICE IS FIXED TO THE GEAR MOTOR BATTERY CHARGER WITH COMPATIBLE ELECTRICAL CHARACTERISTICS WITH THE BATTERY ITSELF; THE CHARGER OUTPUT IS CONNECTED TO THE BATTERY TERMINALS. THE COMP IT IS MADE UP OF THE BLADE CONTROL LEVER, THE GEAR MOTOR, FROM THE BATTERY AND FROM THE BATTERY CHARGER, IT IS PROTECTED BY A SUITABLELY PROTECTED RIGID PLASTIC CASE SHAPED, FIXED TO THE BASE. THE MANEUVER ON THE GROUND OF THE MACHINE BY OF THE OPERATOR, IT IS CARRIED OUT THROUGH A HANDLE, TERMINANT WITH AN ERGONOMIC HANDLE, FIXED AT THE BASE BY MEANS OF A BRACKET WHICH FORMS A PLANE WITH THE GROUND CORNER OF ABOUT 50°. THE POSITION OF THE CENTER OF GRAVITY ALLOWS SELF-CONTAINMENT IN VERTICAL POSITION OF THE LAWN MOWER WITHOUT THE NEED FOR ANY SUPPORT. IN AN APPROPRIATE POSITION, ON THE HANDLE, THERE IS A SWITCH BUTTON WHICH ALLOWS THE OPERATOR TO HAVE VERY EASY CONTROL OF THE OPERATION OF THE MACHINE BY PRESSING (START) OR RELEASE (STOP) MADE WITH THE THUMB FINGER. I CONDUCTORS CONNECTING THE BATTERY TO THE BUTTON AND THIS THE GEAR MOTOR IS HOUSED INSIDE THE HANDLE. ALSO A CABLE IS HOUSED ALONG THE HANDLE, AS LONG AS THE HANDLE ITSELF, TERMINATED WITH A PLUG SOCKET. IN CONDITIONS OF USE THE PLUG IS INSERTED INTO A SOCKET UNDER THE HANDLE WHICH PREVENTS IT FROM BEING DIRTY) AND THE DAMAGE WHILE, IN REST CONDITIONS, THE PLUG IT IS INSERTED INTO A SINGLE-PHASE POWER SOCKET WITH 220 VOLT VOLTAGE TO CARRY OUT THE CHARGING AND THEN THE MAINTAINING THE BATTERY CHARGING; BATTERY IS CHARGED THE CHARGING PROCESS IS INTERRUPTED AUTOMA TICALLY.

Claims

CLAIMS STRUCTURE DESIGNED FOR A LIGHTWEIGHT TOOL, TO BE USED IN AN UPRIGHT POSITION, CHARACTERIZED BY GREAT EASE OF USE THANKS TO A BAND WHEEL WIDE FOR SUPPORT ON THE GROUND AND EASILY MANOEUVRED BY MEANS OF A ERGONOMICALLY DESIGNED HANDLE - GRIP. SAFETY IN USE CHARACTERIZED BY A MOTORIZATION THAT DOES NOT REQUIRE THE USE OF FLAMMABLE FUELS OR THE USE OF ELECTRICAL POWER MAINS VOLTAGE AND FROM A RELATIVE POSITION BETWEEN OPERATOR AND ELEMENT OF CUT WHICH EXCLUDES THE POSSIBILITY OF CONTACT. PRACTICALITY CHARACTERIZED BY THE CREATION OF A GARDENING TOOL GROUPING IN COMPACT WAY THE MOTOR ELEMENT, ITS POWER SUPPLY ACCUMULATOR MEANS AND THE DEVICE FOR CHARGING IT. FLEXIBILITY OF USE CHARACTERIZED BY SMALL DIMENSIONS AND A SHAPING THAT THEY ALLOW USE IN AREAS OF DIFFICULT ACCESS AND IN REDUCED SPACES. RELIABILITY CHARACTERIZED BY THE SIMPLICITY OF THE DRIVE MECHANISM AND FROM THE EASY ACCESSIBILITY OF THE FEW ELEMENTS WHICH MAY REQUIRE A SIMPLE HANDCUFFS MTION.
