Definitions

  • the present invention relates in a general way to paint spray guns.
  • These spray guns are made of extremely strong plastic material and are light and ergo- nomically shaped to facilitate their use by the operator.
  • the methods of micro-painting have been developed for decorating small objects and for producing relatively precise decorative patterns; the positioning of the spray nozzle, relative to the object to be painted and/or the mask, must therefore be as correct and stable as possible.
  • One object of the invention is therefore to provide a spray painting device which can be used to position the object to be painted and/or masked with respect to the spray nozzle.
  • Another object of the invention is to provide a spray painting device which is easy to clean and maintain.
  • the invention proposes a spray painting device comprising a grip part and a spray head mounted on the grip part, in which the spray head comprises, on one side, a spray nozzle, and, on other sides, an air connector for connection to a compressed air supply and at least one paint connector for connection to a paint supply, in which the spray head is exposedly positioned on the grip part, and in which a retaining member, for retaining an object to be painted and/or a mask, is mounted on the spray head, on the same side as the spray nozzle.
  • Figure 1 is a perspective view of the spray painting device of the present invention
  • Figure 2 is a plan view of the device of Figure 1 ;
  • Figure 3 is another perspective view of the device of Figure 1 ;
  • Figure 4 is an exploded perspective view of the device of Figure 1 ;
  • Figures 5 and 6 are perspective views of the device of Figure 1 in use.
  • these show a spray painting device, essentially comprising a grip part 10 and a spray head 20 exposedly mounted on the grip part 10.
  • the spray painting device is connected for operation to a painting system (not shown) of a conventional type, essentially comprising an electronic control unit with a control panel, electrical connections, reservoirs for paint and cleaning fluids, and hydraulic circuits for feeding paints and fluids to the device, together with a pneumatic connection for supplying compressed air from a compressed air source to the device.
  • a painting system not shown
  • the specific configuration of the painting system is not the subject of the present invention.
  • the grip part 10 essentially comprises a casing 11 of plastic material formed by two half- shells 11a, l ib assembled together; this casing 1 1 is ergonomically shaped .to enable a user to grasp the grip part 10 with his hand.
  • a control push button 12 for actuating the device is conventionally placed on the control part 10.
  • Conventional mechanisms and/or control circuits are also provided inside the casing 11, for converting the pressure of the push button 12 to an actuation of the device.
  • it is possible to provide other control members such as pedals, connected for operation to the painting device for its actuation.
  • the spray head 20 is a device of a conventional type, and comprises, on one side, a spray nozzle 21, and, on other sides, an air connector 23 for connection to a compressed air supply AS and at least one paint connector 25 for connection to a paint supply PS.
  • the painting device in question is connectable to a paint supply (for supplying water- or ethanol-based paint, for example), and is also provided with a cleaning connector 27 for connection to a cleaning liquid supply CL (for example demineralized water or ethyl alcohol).
  • a control in particular a switching valve (not shown) positioned on the painting system and connected for operation to the painting device.
  • a screw adjustment device 29 is also positioned on the spray head 20 to control the amount of paint supplied. This control may take the form of coarse adjustment, associated with a fine adjustment system, particularly a potentiometer adjustment system, provided on the control unit of the painting system.
  • the spray head 20 is mounted on the grip part 10 so as to be exposed; this positioning facilitates the maintenance and cleaning of the spray head 20, and in particular the spray nozzle 21.
  • the two half-shells 11a, l ib of the casing 11 have upper ends 11c, l id coupled to the spray head 20 to retain it on opposite sides, in the form of a fork, leaving a front part and an upper part of the spray head 20 exposed.
  • a retaining member 30 adapted to retain an object to be painted and/or a mask (see Figures 4 and 5).
  • the retaining member 30 is fixed to the upper ends l id, l id of the casing 11 of the grip part 10.
  • the retaining member 30 comprises a pair of clamp-like retaining elements 31a, 31b projecting forwards from the spray head 20 and positioned in front of the spray nozzle 21.
  • These clamp-like retaining elements 31a, 31b are formed by respective strips elastically biased towards one another. In Figures 1 to 4, these strips are shown in a rest position.
  • the retaining member 30 is provided with a positioning slider 40 adapted to receive the object to be painted and/or the mask, and positioned so as to be adjustable in respect of its distance from the spray nozzle.
  • the positioning slider 40 comprises a pair of stops 41a, 41b, each of which is inserted into a guide slot 43a, 43b formed on the respective clamp-like retaining element 31a, 31b.
  • each stop 41a, 41b is formed by a screw inserted so as to pass through the respective slot 43a, 43b, and having a head, in particular a head with a slotted recess, for receiving the object to be painted and/or the mask, and by a bolt designed to interact with the head of the screw to hold the stop 41a, 41b releasably on the respective clamp-like retaining element 31a, 31b.
  • FIGs 5 and 6 also show an accessory which can be used with the painting device according to the invention.
  • This accessory comprises a support plate 60 retained by the retaining member 30.
  • opposite lateral edges of the support plate 60 are inserted, respectively, into the slotted recesses of the heads of the screws of the two stops 41a, 41b.
  • the support plate 60 is inserted between the clamp-like retaining elements 31a, 31b which are then spread apart elastically from their rest position shown in Figures 1 to 4.
  • the elastic force exerted by the retaining elements 31a, 31b therefore stably retains the support plate 60.
  • the support plate 60 has a seat 61 adapted to receive the object to be painted OP, and a pattern of through holes 63 (visible in Figure 5) which define a mask for the application of the paint to the object OP.
