- the invention aims to overcome these drawbacks and relates to a plotter whose implementation and maintenance are simple, easy, fast, with a minimum of handling and handling, and allowing draw lines without overflowing paint even on uneven ground strictly plan.
- an apparatus for drawing lines on the ground by application of a paint said device consisting of a chassis mounted on wheels, said chassis supporting a pump fitted with a suction nozzle and a discharge nozzle, said discharge nozzle being connected by a delivery line to a distribution nozzle, is characterized by the that the paint is a ready-to-use paint marketed in a container, such as a canister, having a neck, said chassis comprising receiving means for receiving said paint container and said pump suction nozzle being connected to a suction pipe having a flexible part and being adapted to be introduced into said container to through the neck of it.
- the suction pipe carries a plug which it cross member and which is adapted to cooperate with the neck of the container; cap has a rim whose external diameter is larger than that of the neck of the container so that the cap is adapted to abut on said neck through said flange.
- the plug is crossed by a central passage for the venting the interior of the container.
- the plug comprises a body of general shape cylindrical into which a channel arranged parallel to the axis has been inserted longitudinal of the plug and whose axial length is greater than that of cap so that its ends protrude axially from the cap to constitute connection nipples to which the pipe is connected suction.
- the discharge chamber of the pump has a outlet connected to a return pipe also passing through the plug; in the body was inserted a channel arranged parallel to the longitudinal axis of the plug and whose axial length is greater than that of the plug so that its ends protrude axially from the plug to form connection fittings to which the return pipe is connected.
- the channels are metallic and have been inserted by overmolding or press fitting.
- the plug is made from a single piece of molded material.
- the paint flow rate through the dispensing nozzle is adjustable.
- the dispensing nozzle is carried by a support removably mounted on a support tube carried by the device.
- the pump is electrically driven from a battery placed in a tray carried by the device.

- the chassis 1 comprises receiving means 8 produced in the form a cradle consisting of two U-shaped stirrups 18, 19; the caliper 18 is secured to the rear transverse beam 13, and the stirrup 19 is secured to a cross member 20 welded to the longitudinal member 12 being parallel to the member rear transverse 13; of course, the stirrups 18 and 19 extend in vertical planes parallel to the transverse plane of the device, being open towards the top ; the four upper ends of the two stirrups 18 and 19 support a belt 21 of generally rectangular shape; two side straps 22 extending parallel to the belt 21 connect the wings of the stirrups 18, 19 in U shape for good mechanical strength of the receiving means 8.
- the chassis 1 supports a tray 23 for a battery 24; the tank 23 rests on the longitudinal beam 12 and on a cross 25 connected by its ends on one side to the longitudinal beam 12 and the other side at cross 20; the tray 23 is secured to the longitudinal beam 12 and the cross 25 for example by welding.
- the terminals 26, 27 of the battery 24 allow the power supply of the electric pump 3 under the control of a switch 28, by via a connection box 29 and a connector 30.
- the pump 3, supported by the chassis 1, has a nozzle for discharge 5 to which is connected a discharge line 6 for feeding a distribution nozzle 7; on this pipeline from delivery 6 are provided: a shock absorber 31 carried by the belt 21 of the receiving means 8, to dampen the jerks of the flow delivered by the pump 3, a tap 32 making it possible to close or open the passage through the discharge line 6, and a valve 33 for adjusting the flow rate of the paint distributed by the distribution nozzle 7.
- the dispensing nozzle 7 is placed at the end of a tube 34 at the other end of which is connected the discharge line 6.
- the longitudinal beam 12 carries vertically a amount 35; on this upright 35 is slidably mounted a sleeve 36 whose height position on the upright 35 is adjustable and maintained by a screw 37.
- the sleeve 36 is integral with the sleeve 38 of a wind screen 40 by through a spacer 39.
- the spacer 39 is inclined by relative to the longitudinal axis of the device so that the sleeve 38 of the wind screen 40 is situated practically in the vertical longitudinal median plane of the device, that is to say in the vertical plane which contains the handlebar support 15; this same plane also contains a vertical sight 41 carried at the front by the wind screen 40, which facilitates the implementation of the apparatus to be traced.
- a support tube 42 Inside the sleeve 38 is slidably mounted a support tube 42 whose height position is adjustable and maintained by a screw 43; the tube 34 which carries the nozzle 7 is secured inside a support member 61 placed in the support tube 42; it has a flange at its upper part 44 by which it abuts on the upper edge of the support tube 42.
- the tap 32 and the valve 33 are advantageously supported by the spacer 39.
- the section of the discharge line 6 between the valve 33 and the tube 34, which carries the nozzle 7, is flexible, this facilitating the positioning of the tube 34, therefore of the nozzle 7, in the support tube 42, as well as its withdrawal.
- the other sections of the discharge line 6, one between the tap 32 and the damper 31, the other between said damper 31 and the discharge nozzle 5 of the pump 3 are also provided flexible according to the example shown but of course these two sections could be rigid type.
- the pump 3 has a suction nozzle 4 to which is connected a end of a suction line 10 on which a filter 45 is placed fixed to the chassis 1, here on a side strap 22 connecting the stirrups 18 and 19 of the cradle constituting the receiving means 8.
- the suction line 10 carries a device 11, designated by the plug 11 whose role will appear below.
- the section 46 of the suction line 10 between the filter 45 and the plug 11 is a flexible section; in the example shown the section between the filter 45 and the suction nozzle 4 of the pump 3 is also flexible but of course it could be rigid.
- the plug 11 comprises a body 47 of generally cylindrical shape, with cross-section circular, advantageously made of plastic or rubbery material, in which have been inserted, by overmolding or press fitting, two channels 50, 51 of metal arranged parallel to the longitudinal axis of the plug 11, the axial length is greater than that of the plug 11 so that their ends protrude axially from the plug 11 to form end caps connection; thus, each channel 50, 51 defines an axial passage through the plug 11, respectively 52, 53.
- the body 47 of the plug 11 is crossed by a passage central 54.
- the body 47 has a circular rim 55 extending radially beyond the external cylindrical surface of the body 47.
- the section 46 of the suction line 10 is connected to the part upper part of channel 50, the lower part of which carries a suction section 48 proper free end advantageously bevelled.
- the discharge chamber of the pump 3 has an outlet 56 other that that constituted by the discharge end piece 5; this output 56 is connected by a pipe 57 said to return to the upper part of channel 51 of the plug 11, channel 51, the lower part of which carries a return section 58, of length less than that of the suction section 48.
- an adjusting member 59 is provided, needle valve type, allowing to regulate the flow through the pipe back 57; the adjusting member 59 is secured to the chassis 1 and carries itself a pressure gauge 60, visible in FIG. 2, indicating the pressure of discharge of pump 3 in operation.
- the section of the return pipe 57 comprised between the adjustment 59 and the plug 11 is provided flexible; the section of this pipeline return 57 between the adjusting member 59 and the pump 3 is flexible also, according to the example shown, but could be rigid.
- the user When the user wishes to draw lines on the ground with the device according to the invention, it takes a container or can 9 in which a paint ready to the job is marketed and places this container 9 in the cradle constituting the receiving means 8 of the device; these means are arranged to receive a container 9 containing for example twenty liters of paint ready to use, which is the most commonly used size.
- the interior of container 9 is permanently at atmospheric pressure, even if the plug 11 fits perfectly inside the neck 49; we will understand that this adjustment is not essential, the outside diameter of the plug 11 may be less than the inside diameter of the neck 49, provided that the circular rim 55 of the plug 11 has a diameter sufficient to rest on the upper edge of neck 49.
- the width of the drawn line is also adjusted by modifying the height of the nozzle 7 with respect to the ground, thanks to the screw 43.
- the device may not have a return circuit, in which case the plug 11 would only include the channel 50 and the central passage 54.
- FIG. 8 shows a variant of plug 11 according to which it is in one piece obtained by molding.
- the pump 3 is driven electrically from the battery 24; alternatively, the apparatus comprises a pump driven mechanically from the wheels when the device is pushed for tracing.
- the line drawing operation at soil requires a shorter time than that obtained with the known devices to this day ; the cost of the tracing operation, also taking into account the ease with which the device is cleaned and maintained is also reduced.
