  • Some of these devices consist of a chassis mounted on wheels, which chassis supports a pump provided with a suction nozzle and a discharge nozzle; the discharge end piece is connected by a discharge line to a distribution nozzle distributing a paint for the production of lines on the ground, such as the lines delimiting playgrounds for example; for its application, the paint is poured from a container, such as a can, in which it is sold, in a tank integral with the chassis of the apparatus, the suction pipe, most often rigid, being also connected at the bottom of the tank.
  • US-A-4,624,602 describes an apparatus for drawing lines on the ground by applying a paint, said apparatus consisting of a chassis mounted on wheels, said chassis supporting a pump provided with a suction nozzle and d 'a discharge nozzle, said discharge nozzle being connected by a discharge pipe to a dispensing nozzle; nothing is provided in this document to facilitate the maintenance of the device, and the paint that the device is required to spray under pressure is contained in a bucket or a tank and no details are given concerning this container. .
  • US-A-5,213,480 also describes an apparatus for drawing lines in which the motor-pump assembly is vertically movable to facilitate the change of the paint container; the latter, shown in dashed lines, has a large specific slit cover for the passage of the suction members of the pump; sports fields, on which the device is required to draw lines, not always being strictly planar, such a cover can cause a significant overflow of paint, the latter being of the fluid type.
  • the invention aims to overcome these drawbacks and relates to a drawing device whose implementation and maintenance are simple, easy, fast, with a minimum of handling and handling, and for drawing lines without overflow of painting even on ground that is not strictly level.
  • an apparatus for drawing lines on the ground by applying a paint consisting of a chassis mounted on wheels, said chassis supporting a pump provided with a suction nozzle and a discharge nozzle, said discharge nozzle being connected by a discharge pipe to a dispensing nozzle, is characterized in that the paint is a ready-to-use paint sold in a container, such as a can, having a neck, said chassis comprising receiving means intended to receive 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 through the bottleneck of it.
  • the suction pipe carries a plug which it passes through and which is adapted to cooperate with the neck of the container;
  • the stopper has a rim whose outer diameter is larger than that of the neck of the container so that the stopper is adapted to come into abutment on said neck through said rim.
  • the cap is crossed by a central passage for venting the interior of the container.
  • the plug comprises a body of generally cylindrical shape into which has been 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 suction pipe is connected.
  • the discharge chamber of the pump has an outlet connected to a return pipe also passing through the plug; in the body has been 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 nipples to which the return pipe is connected .
  • the channels are metallic and have been inserted by overmolding or force 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 member removably mounted on a support tube carried by the device.
  • the pump is electrically driven from a battery placed in a tank carried by the device.
  • the marking device consists of a chassis 1 essentially comprising a longitudinal spar 12, a rear transverse spar 13, carrying at each of its ends a wheel 2; and a front transverse half-member 14 for a third wheel 2; connected to the rear transverse beam 13, an inclined handlebar support 15 supports, in adjustable height, a sleeve 16 secured to a handlebar 17 for driving the device.
  • the chassis 1 comprises receiving means 8 produced in the form of a cradle constituted by two U-shaped stirrups 18, 19; the stirrup 18 is secured to the rear transverse beam 13, and the stirrup 19 is secured to a cross member 20 welded to the longitudinal beam 12 while being parallel to the rear transverse beam 13; of course, the stirrups 18 and 19 extend in vertical planes parallel to the transverse plane of the device, being open upwards; the four upper ends of the two stirrups 18 and 19 support a belt 21 of generally rectangular shape; two lateral straps 22 extending parallel to the belt 21 connect the wings of the stirrups 18, 19 in a U shape for good mechanical strength of the receiving means 8.

  • the terminals 26, 27 of the battery 24 allow the electrical supply of the electric pump 3 under the control of a switch 28, via a connection box 29 and a connector 30.
  • the pump 3, supported by the chassis 1, comprises a discharge nozzle 5 to which is connected a discharge line 6 for the supply of a distribution nozzle 7; on this pipeline from delivery 6 are provided: a damper 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 delivery pipe 6, and a valve 33 making it possible to adjust the flow rate of the paint dispensed by the dispensing nozzle 7.
  • the dispensing nozzle 7 is placed at the end of a tube 34 at the other end to which the delivery pipe 6 is connected.
  • the longitudinal beam 12 carries a vertical post 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 means of a spacer 39.
  • the spacer 39 is inclined 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 bush 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 at its upper part a flange 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, thus that his withdrawal.
  • the other sections of the discharge line 6, one between the valve 32 and the damper 31, the other between said damper 31 and the discharge end 5 of the pump 3 are also provided flexible according to the example shown, but of course these two sections could be of the rigid type.
  • the pump 3 includes a suction nozzle 4 to which is connected one end of a suction pipe 10 on which is placed a filter 45 fixed to the frame 1, here on a side strap 22 connecting the stirrups 18 and 19 of the cradle constituting the reception means 8.
  • the suction line 10 carries a device 11, designated by the plug 11, the role of which 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, of circular section, advantageously made of plastic or rubbery material, into which have been inserted, by overmolding or force fitting, two metal channels 50, 51 arranged parallel to the longitudinal axis of the plug 11, the axial length of which is greater than that of the plug 11 so that their ends protrude axially from the plug 11 to form connection end pieces; 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 central passage 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 pipe 10 is connected to the upper part of the channel 50, the lower part of which carries a suction section 48 with a free end advantageously bevelled.
  • the discharge chamber of the pump 3 has an outlet 56 other than that constituted by the discharge nozzle 5; this outlet 56 is connected by a pipe 57 known as the return pipe to the upper part of the 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, of the needle valve type, making it possible to adjust the flow rate through the return pipe 57; the adjusting member 59 is secured to the chassis 1 and itself carries a pressure gauge 60, visible in FIG. 2, indicating the discharge pressure of the pump 3 in operation.
  • the section of the return pipe 57 included between the adjusting member 59 and the plug 11 is provided flexible; the section of this return pipe 57 between the adjusting member 59 and the pump 3 is also flexible, according to the example shown, but could be rigid.
  • the user When the user wishes to draw lines on the ground with the apparatus according to the invention, he takes a container or can 9 in which a ready-to-use paint is sold and places this container 9 in the cradle constituting the receiving means 8 of the apparatus; these means are arranged to receive a container 9 containing for example twenty liters of ready-to-use paint, which is the most commonly used size.
  • the user plunges into the container 9, through the neck 49, the suction 48 and return 58 sections until the circular flange 55 of the cap 11, carried by the suction and return pipes 57 and 57, rests on the upper edge of the neck 49 of the container 9; in this position, as shown in FIG. 6, the end of the suction section 48 is practically in contact with the bottom of the container 9, that of the return section 58 being at a distance from this bottom.
  • the interior of the container 9 is permanently at atmospheric pressure, even if the plug 11 fits perfectly inside the neck 49; it will be understood that this adjustment is not essential, the outside diameter of the plug 11 possibly being 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 the neck 49.
  • the width of the drawn line is also adjusted by modifying the height of the nozzle 7 relative to the ground, using the screw 43.
  • the device could not include a return circuit, in which case the plug 11 would only include the channel 50 and the central passage 54.
  • Figure 8 shows a variant of plug 11 according to which it is in one piece obtained by molding.
  • the pump 3 is electrically driven from the battery 24; alternatively, the device comprises a pump driven mechanically from the wheels when the device is pushed for tracing.
  • the operation of tracing lines on the ground requires a shorter time than that obtained with the devices known to date; the cost of the tracing operation, also taking into account the ease with which the device is cleaned and maintained, is also reduced.
