Definitions

  • the present invention relates to a compact vehicle which is intended for cleaning surfaces, in particular for picking up litter left on the sidewalks such as papers, cigarette packs, etc.
  • a vehicle which can advantageously be used by an operator fitted with roller skates essentially consists of a support frame provided with two non-steerable rear wheels, at least one caster mounted idly on a pivot at the front and a operating handlebar disposed at the rear of said chassis.
  • This chassis supports, on the one hand, a fixed apparatus for collecting litter which comprises a suction head which is in contact with the ground and which communicates with a receptacle for litter, the suction being created by a turbine, and, on the other hand, a mobile sampling stick also operating by suction.
  • the fixed device is used for normal cleaning of the surface and the stock is used manually by the operator to pick up trash located in places inaccessible to the fixed device, for example along a wall or for picking up dog excrement.
  • the present invention relates to a vehicle of the aforementioned type which is self-propelled, whose mechanical design is extremely simple and whose noise is limited.
  • the fixed device and the movable stock constitute fully autonomous units, the vehicle is self-propelled and the fixed device, the mobile stock and the vehicle are each driven by a separate motor, the various motors being supplied with energy. by a power generator group with thermal engine.
  • a power generator group and separate motors for each of the constituent elements of the vehicle makes it possible to very greatly reduce the noise created by the vehicle, the heat engine of the power generator group operating at constant speed; moreover, the power generator group constitutes a unit which can be easily isolated from a sound point of view.
  • the use of a group allows the driving of many different devices autonomously, the mechanical connections which would have been necessary in the case of a single thermal drive motor common to all the units being replaced by cables. or easily disconnectable pipes.
  • the power generator group is in fact a generator and the drive motors of the various members are electric motors.
  • the different motors are hydraulic motors and the power generator group always includes a thermal motor which drives one or more hydraulic pumps with variable flow which supply the different motors.
  • the suction turbine of the stationary appliance is placed in the waste evacuation pipe which connects the suction head to the receptacle. Thanks to this arrangement, the detritus which is removed crosses the blades of the turbine and therefore undergoes a mechanical treatment which makes it possible to shred and compact them so that they occupy a much lower volume in their receptacle.
  • the wheels are provided with a brake controlled by a first handle disposed on a handlebar disposed at the rear of the vehicle, the rest position of this first handle corresponding to the locking position of the wheels; moreover, the mechanical connection between the wheels and their drive device is controlled by a second handle also disposed on the handlebars, the rest position of this second handle corresponding to the disengaged position of said mechanical connection.
  • a safety command is obtained since, if the handles are released, the device stops immediately because on the one hand the mechanical drive is removed and on the other hand the brakes are applied .
  • the handlebars comprise a switching device for each of the vehicle units, namely the movable stock, the fixed device and the wheel drive motor. Thanks to this arrangement, each of the units can be controlled and operated separately, the power generator group operating continuously; in particular, one unit can be operated at a time, which makes it possible to limit the power of the power generator group to the greatest of the maximum powers of said units.
  • the wheel drive device is constituted by a motor actuating a shaft carrying at least one roller, the assembly of the motor and rollers being mounted movable between two positions, a declutching position and a driving position in which the or the roller (s) is (are) in contact with the tread of a wheel.
  • This drive device has the advantage of great simplicity from the point of view of its realization; moreover, it makes it possible to obtain progressive drive of the wheels when starting the vehicle.
  • the rear wheel drive device is constituted by two identical hydraulic motors with variable flow rate each associated with one of the rear wheels, these two hydraulic motors being mounted in a hydrostatic bridge .
  • the movable butt can advantageously be constituted by a device particularly suitable for the collection of dog excrement; such a device comprises a suction bell, which is provided with at least one spray nozzle and which is connected by a suction pipe to a waste water storage tank, the spray nozzle being supplied by a source of pressure washer.
  • this source of pressurized cleaning agent comprises a self-regulated compressor at constant pressure, that is to say a compressor which stops when the cleaning agent is subjected to a determined pressure. Obviously this compressor is driven by another motor.
  • the movable stock comprises a trigger which actuates a valve arranged in the conduit for supplying the bell with pressurized cleaning agent.
  • the device shown in figs 1 to 4 comprises a chassis 1 which supports a generator 2 comprising a heat engine which drives an electric current generator such as an alternator and which is supplied by a tank 3.
  • the chassis 1 is supported by two rear wheels 4 and 5 which are not steerable and by a front caster 6 mounted idly pivotally on a vertical axis.
  • a caster 7 is arranged next to each of the rear wheels in front of the axis of the latter; this caster is located at a relatively small distance from the ground, for example three centimeters to allow the vehicle to be able to easily climb on sidewalks shown diagrammatically at 8 in FIG. 2.
  • the chassis which has just been described supports two cleaning devices, a fixed device placed at the front and a movable stick 9 which is placed at the rear of the vehicle and which is actuated and moved by the operator who is advantageously wearing shoes. skates on wheels and guides the vehicle by means of a handlebar 11 disposed at the rear of the vehicle.
  • the fixed appliance is shown in detail in FIG. 3. It essentially comprises a suction head 12 which is in contact with the ground, for example by means of a flap or brush 13 disposed along the rear edges and lateral of the head 12; the latter has on its front edge a bar 14 whose height is adjustable so as to adjust the suction force.
  • Two rotary brushes 15 and 16 are arranged on either side of the suction head 12 in front of the latter; they rotate in opposite directions as indicated by arrows in FIG. 1 so as to cause the detritus to converge towards the suction head 12.
  • the suction vacuum is created by a turbine 17 which is located directly above the suction head 12 at the start of the conduit 18 for evacuating the collected detritus which brings the latter into a receptacle 19 which can for example be lined a trash bag.
  • a movable flap 21 is disposed at the mouth of the conduit 18 in the receptacle 19 so as to avoid the backflow of detritus into the conduit 18.
  • the receptacle 19 has a cover 22 which can be opened by the operator in the event that this the latter manually picks up large trash.
  • the set of mobile elements constituting this first cleaning unit is driven by an electric motor 23 which directly drives the turbine 17 and the rotary brushes 15 and 16 by means of belts 24 and 25, the belt 25 being disposed between the two brushes and being crossed so as to allow opposite rotation of the two brushes.
  • the movable stock is advantageously made up of a device which is particularly suitable for collecting canine faeces and which essentially comprises a suction bell 31 which is provided with a nozzle connected to a pressure cleaning agent and the jet of which is directed practically tangentially to the ground; the movable stock also comprises a suction device which comprises a vacuum chamber 32 which is for example placed under vacuum by means of a turbine and which is connected to the suction bell 31 by a conduit 33 of disposal of waste water and excrement.
  • the cleaning agent is kept under pressure by means of a compressor or a pump which is regulated so as to maintain a constant pressure; this compressor or this pump is driven by an electric motor which is stopped as soon as the necessary pressure is obtained.
  • the cleaning agent being always under pressure
  • the control of the movable stock is obtained by a trigger 34 arranged on the supply pipe for cleaning agent under pressure, the turbine for depressurizing the enclosure 32 then being actuated .
  • the chassis drive is obtained by means of a motor unit comprising another electric motor which drives a shaft carrying at each of its ends a roller 41, the assembly of the electric motor and the shaft is arranged in a casing 42
  • the drive of the wheels is obtained by means of a handle 35 which is disposed on the handlebar 11 and which in its rest position shown in FIG. 4 places the assembly of the casing 42 and the rollers 41 at a certain distance from the wheels 4 and 5.
  • the handlebar 11 has another handle 36 which controls brakes acting on the wheels 4 and 5.
  • this handle 36 is mounted in reverse manner with respect to the normal arrangement. as already explained for the handle 35, that is to say that in the rest position shown in Figure 4, the brakes are applied and the wheels are locked. In this way, positive security is obtained since the release of the two handles causes the vehicle to stop immediately. This is particularly important in view of the fact that the vehicle can be driven on sidewalks where there are many passers-by.
  • the handle also includes a control panel 37 which has three switches 43, 44, and 45 and a safety button 46.
  • the electric switches 43 to 45 each control one of the vehicle units according to the invention; the switch 43 controls, for example, the electrical power supply to the wheel drive motor, the switch 44 similarly controls the drive motor 23 of the stationary cleaning device and the switch 45 controls the turbine movable butt suction. In this way, each of the units can be operated in isolation, which limits the power required to be supplied by the generator.
  • the emergency button 46 which can be a key button of the ignition key type is a safety button, the actuation of which brings about the stopping of the engine of the generator set, that is to say the complete stopping of the vehicle according the invention; it is therefore an emergency device for stopping all of the vehicle's units.
  • FIGS. 5 and 6 represent respectively in top view and in side view an alternative embodiment of the fixed sampling device on which there are the two lateral brushes 15 and 16, the suction head 12, the flap 13, the turbine 17 and the discharge duct 18.
  • Figures 1 and 4 relate to an "electric" embodiment of the vehicle according to the invention, that is to say in which the power generator group is a generator and the various drive motors, electric motors; according to another embodiment, the propellant and engine assembly is of the hydraulic type, that is to say that the power generator group is constituted by one or more hydraulic pumps with variable flow driven by a thermal engine and the various drive motors are constituted by hydraulic motors supplied by said pumps.
  • Figure 7 is the hydraulic diagram of such a version of the vehicle according to the invention. The hydraulic power is supplied, in this case, by two variable flow pumps 61 and 62 which are driven by a heat engine not shown.
  • the hydraulic pump 61 supplies two hydraulic motors 54 which are used to drive the brushes vertical lateral; the pump 62 supplies on the one hand a hydraulic braking device 63 and, on the other hand, by means of a three-way hydraulic distributor 64, the hydraulic motor 65 for driving the horizontal transverse brushes, the hydraulic motor 55 for driving the turbine and the hydraulic motor 66 for driving the turbine of the movable stock.
  • the internal combustion engine also drives a variable-flow pump 67 which supplies the rear wheel drive device 69 via a two-position hydraulic distributor 68.
  • the hydraulic distributor 68 is controlled by the handle 35 which constitutes an advance control of the "dead man” type, that is to say that the advancement of the vehicle according to the invention must be voluntarily controlled by actuation of this handle 35.
  • the drive 69 consists of two hydraulic motors 71 and 72 which each drive one of the two rear wheels 4 and 5 and which are mounted so as to constitute a hydrostatic bridge.
  • the brake 63 is of the positive safety type, that is to say that it supplies two braking devices 73 and 74 each associated with one of the two rear wheels 4 and 5, so that the wheels are released when the hydraulic pressure is applied, this brake is controlled by the handle 36 so that the hydraulic pressure is applied to the braking devices 73 and 74 when this handle is actuated.
  • the braking device 63 includes an accumulator 75 and a distributor 76 which enables the devices to be put braking 73 and 74 momentarily under pressure to perform an operation of the stopped motor vehicle.
  • the three-position hydraulic device 64 corresponds to the electrical switches 43, 44 and 45 and constitutes a switching device making it possible to select three modes of use of the vehicle according to the invention.
  • the hydraulic switch 64 is shown in the position where only the vehicle drive motors 71 and 72 can be powered; in this case, the vehicle can move without operating the sampling devices.
  • the three-position switch is pushed to the right, the displacement of the vehicle is obtained and the motors 54, 55 and 65 of the brushes and of the turbine of the fixed sampling device are supplied at the same time.
  • the hydraulic switch is pushed to the left, the motors 71 and 72 for driving the vehicle are no longer supplied with power, and only the operation of the hydraulic motor 66 of the sampling stick is obtained.
  • a hydrostatic bridge 69 makes it possible to carry out a differential drive of the two rear wheels 4 and 5; moreover, the use of hydraulic motors makes it possible to easily obtain a speed variation which is controlled by a rotary handle disposed on the handlebar 11 at one of the ends of the latter and which makes it possible to carry out a control similar to the "joystick of the gas "from a motorcycle. It is also possible to provide a reversing device controlled by an unlocking lever so as to avoid any involuntary manipulations reversing the vehicle according to the invention.
  • the invention makes it possible to obtain a cleaning vehicle which is of particularly simple design since the mechanical connections are eliminated and replaced by connections.
  • electrical or hydraulic in the form of cable or pipe which allows great flexibility for mounting and also which facilitates the maintenance of the various units of the device.
  • the use of a power generator group driven by a heat engine makes it possible to drive each of the units by an individual engine, the various engines being able to be easily stopped and restarted, which is not the case for heat engines. .
  • a power generator group driven by a heat engine also makes it possible to greatly reduce the noise produced by the vehicle according to the invention since the heat engine rotates at constant speed. So for example, we can make a device that does not provide more than 85 dB acoustic.
  • the device according to the invention has very high security, which is particularly important in view of the fact that it must be used in places where the public is located.
