Definitions

  • the invention relates to a vehicle for continuous application of a stripe to a surface, such as a stripe for marking areas in a sports ground or applying lines to a roadway, said material being liquid while being applied, and said vehicle comprising a frame with a handle, travelling wheels mounted rotatably on the frame, a container for the material, and a nozzle facing downwards in the position of use of the vehicle designed to emit the material onto the underlying surface of the vehicle, a conduit between the container and the nozzle and a pump cooperating with the conduit designed for pumping the material to the nozzle in an amount relative to the capacity of the nozzle dependent on the immediate speed of the vehicle.
  • a device for applying a stripe to a surface is known from NO published specification no. 152,459.
  • This known device uses an aerosol sprayer as container and nozzle, said aerosol sprayer being attached to the device with the nozzle facing downwards.
  • Means are provided in the device in order that an operator, who pushes the device by holding the handle, from the handle can actuate the valve of the aerosol sprayer in order that the liquid material is dispensed through the nozzle and down onto the surface.
  • Aerosol sprayers are expensive to produce and use, and they are often a danger to the environment when freon is used as propellant gas. Their capacity is often limited, and consequently a large number of aerosol sprayers must be used when paint stripes are to be applied to a sports ground where areas are to be marked by means of the said stripes.
  • DE-A-27 10 013 provides a vehicle substantially of the kind referred to in the preamble.
  • This known vehicle is driven by a motor, and the pump is removably attached to the axle of the driving wheels.
  • the pump is driven through a chain drive connected to the axle of the driving wheels. No further information as to the kind of pump is given, but presumably the pump is a gear or piston pump.
  • a device for applying a stripe to a surface is known from FR-A- 2 570 724.
  • This known device has means for measuring the speed of the device across the surface and for dosing the quantity of dispensed material depending on the measured speed.
  • the above vehicle and the above device are both highly complex in their construction, thus making them expensive to buy, use and maintain and, besides, they are so heavy that it is necessary to drive them by means of a motor.
  • the vehicle must be inexpensive to buy, use and maintain, and it must be so light that an operator can move the vehicle without difficulty and without the help of a motor.
  • a vehicle according to the invention being characteristic in that the conduit is an elastomer hose extending substantially in the preselected travelling direction of the vehicle and describing a semi-circle having its centre in a wheel axle being connected to one of the wheels, said wheel axle having a number of radially projecting arms with rollers being rotatably mounted on the free ends of the arms, the axes of said rollers extending parallel to the wheel axle and at a radial distance therefrom which allows interaction between the rollers and the semi-circular part of the hose in such a manner that the semi-circular part can be compressed at least partially by the rollers.
  • nozzle and container are two separate parts it becomes possible to use containers of any size in order to hold large quantities of spray material in the vehicle so that the quantity can be adapted to the expected consumption of spray material before it solidifies or dries.
  • This large material capacity also allows bulk purchasing of spray material.
  • the hose pump can also pump spray material to the nozzle when the vehicle is pushed in the preselected travelling direction, when the connection between the hose pump and the travelling wheel is only established in the direction of rotation corresponding to the preselected travelling direction.
  • This connection can for instance be established by a generally known one-way coupling. Without such a one-way coupling the spray material would be pumped back into the container, and the conduit be emptied of spray material if the vehicle is moved in the opposite direction so that spraying could not be resumed until the vehicle had been pushed a distance in the preselected travelling direction. The operator can therefore move the vehicle from one place to another merely by pulling the vehicle after him which would hardly be possible with other types of pumps.
  • the means according to claim 3 facilitate a simple altering of the capacity of the hose pump by adjustment of the tension of the adjustable spring if this should be required due to the viscosity of the spray material and the quality of the surface.
  • a vehicle for continuous application of a stripe of spray material to a surface 1 comprises a frame 2 provided with a front pair 3 and a rear pair of travelling wheels 4, said wheels 3, 4 being distanced in the longitudinal direction of the vehicle and at the four corners of the frame of the vehicle.
  • the frame 2 is provided with a handle 5 extending to the rear/upwards from the vehicle, said handle 5 being vertically adjustable in a manner which is not shown, so that it can be adjusted to a position which is convenient for the operator.
  • a downwards turned nozzle 6 is situated by the front wheels 3 which nozzle can be adjusted upwards and downwards in a manner which is not shown so that the mouth 7 of the nozzle 6 can be adjusted in a position suitable for its particular purpose.
  • the nozzle 6 is connected with a container 9 which is designed to hold a suitable quantity of liquid spray material which conduit 8 travels up along the side of the container 9 and down into it from above so that liquid spray material cannot by its own force under the influence of the force of gravity flow to the nozzle 6 and out of its mouth 7.
  • the conduit 8 is a hose of an elastomer, such as rubber or a similar plastic material.
  • the conduit 8 describes a circular arc 8a of approximately 180° around the rear wheel axle 10 having this as its centre and at a preselected radial distance from the said wheel axle 10.
  • the rear wheel axle 10 By means of a one-way coupling the rear wheel axle 10 is connected stationarily to at least one of the rear wheels 4, and between the wheels 4 the wheel axle 10 has radially projecting arms 11 which on their free ends carry rotary rollers 12 whose axes extend parallel to the wheel axle 10, whereby the rollers 12 extend axially opposite the conduit 8.
  • the radial distance of the rollers 12 is adapted to the radial distance of the circular arc 8a from the rearmost wheel axle 10 in such a manner that the rollers 12 can compress the elastomer conduit 8 at least partially.
  • the rollers 12 will then compress the conduit 8 in the semi-circle 8a in a sliding movement from the rearmost point of said semi-circle 8a of the conduit 8 to the front-most point, whereby a forwardly progressing suction effect is created in the conduit 8 so that spray material is sucked from the container 9 and from the described hose pump 8a, 10, 11, 12 pressed out through the mouth 7 of the nozzle 6 and down onto the surface 1.
  • a yoke 13 is arranged in the frame 2 said yoke being pivotably mounted in the upwards and downwards direction about a horizontal axle 14 mounted in the frame 2 so that the yoke 13 describing a substantially semi-circular longitudinal section is designed for its semi-circular part to rest on that side of the semi-circular part 8a of the conduit 8 turning away from the wheel axle 10.
  • the rod 17 is surrounded by a pressure spring 19 in such a manner that it can press the free end 15 of the yoke 13 downwards, whereby the semi-circular part of the yoke 13 can press the conduit 8a to a more or less intimate interaction depending on the tension of the pressure spring 19.
  • the tension of the pressure spring 19 is adjustable in a manner (not shown) which may for instance consist of a number of recesses along the rod 17 of which one may optionally be brought in mesh with a tooth or ratchet of the bushing 18 so that the rod 17 can be held fixedly in the bushing 18.
  • a pressure vessel 20 is inserted in the conduit 8 said pressure vessel having such a size that it will partly serve to balance any pressure fluctuations in the hose pump and partly will enable a brief discharge of paint even though the vehicle is not being moved forwards.
  • the capacity of the described type of pump can be adapted to the required capacity by changing the diameter of the hose, the pressure of the rollers on the hose, the number of rollers or by designing the conduit as several parallel hoses.
