Definitions

  • the invention relates to paint or similar material spray guns and, more particularly, it relates to the system for supplying such guns with paint or other material to be sprayed.
  • Spray guns of this type currently known are generally supplied with paint from a reservoir cup which is disposed under the spray gun while being connected to the spray orifice thereof by a duct oriented perpendicular to the axis of the spray gun. .
  • This arrangement of the paint reservoir cup sometimes proves to be impractical when the configuration of the parts to be painted requires orienting the spray gun in certain positions.
  • Document FR-A-2363375 discloses a compressed air gun for spraying fluid substances such as paint, which in its embodiment of FIGS. 2 and 3, is equipped with a gravity feed device .
  • the paint container is connected laterally by means of a sleeve which is mounted for free rotation on a hollow shaft opening into the gun.
  • An annular chamber is formed between the sleeve and the hollow shaft, and communicates with an internal channel of the latter.
  • the object of the present invention is to remedy the drawbacks presented by known supply devices for spray guns for painting or the like, and for this purpose it proposes a gravity supply device which, while being of a great simplicity and low cost, ensures a perfect supply of paint to the gun regardless of the inclination given to it, with an excellent seal without the use of seals and which allows the gun to be perfectly balanced in the hand regardless of its position of use.
  • the gun is supplied from a connector which projects laterally with respect to the body of the gun, being oriented in a direction practically perpendicular to the plane of the latter.
  • This hollow connection engages the hollow interior part of a connecting piece into which opens, via a rigid conduit, the open lower end of the bucket forming a paint reservoir.
  • the body of the fitting On its intermediate part, has a groove profile with radial openings allowing the paint to flow. inside the fitting.
  • Conical surfaces on the opposite faces of the connecting piece are designed which, in the device's position of use, are clamped against parts of conjugated conical shape presented on the one hand by one end of the body of the fitting and, on the other hand, by a blind clamping nut screwing onto the threaded free end of the fitting.
  • the device thus achieves, by tightening the nut, an excellent seal that does not require the use of seals and that it allows, depending on the position of use of the gun, to adjust the inclination of the bucket by pivot around the fitting, and fix the bucket in the position thus chosen, so as to always allow a good flow by gravity of the paint out of the bucket and a good balancing of the device in the hand of the user.
  • a spray gun for spraying paint with at 2 a compressed air inlet pipe extending the butt 3, at 4 the spray nozzle and at 5 the control trigger.
  • a tubular connector 6 projects from the front part of the gun 1, the inner end 7 of this connector opening into a supply chamber (not shown in the drawing) located upstream of the spray nozzle 4.
  • the body of the connector 6 has, from its inner end 7, a portion 8 of larger diameter continuing with a conical portion 9 itself extended by a cylindrical portion 10.
  • the cylindrical portion 10 has a groove peripheral 11 radially pierced with four openings 12 communicating with the interior of the fitting. The body of the latter ends outwards by a threaded part 13.
  • the bucket 14, forming a paint reservoir is made of a rigid plastic material and has a cylindrical body continuing at its base by a conical part in the form of a funnel.
  • the bucket 14 is closed at its upper part by a screwable cover 15 and it has at its lower end an outlet orifice 16 which is screwed into the upper part 17 of a rigid conduit 18 having at its intermediate part a connecting piece 19.
  • the part 19 has, oriented perpendicular to the axis of the rod 18, a bore 20 of circular section at the upper part of which opens, through an opening 21, the end of the hollow rod 18.
  • the part 19 has a conical bearing surface respectively 22, 23 and it continues, at its lower part, with a support leg 24.
  • the part 19 is designed to receive, in its bore 20, the body of the connector 6, the conical surface 22 of the part 19 coming to apply in sealed manner against the conjugate conical part 9 of the connector 6.
  • a cap nut 25, having at its open end a conical part 26 is screwed onto the threaded end 13 of the body of the connector 6 so that this conical part 26 comes engage the conjugate conical bearing surface 23 of the connecting piece 19.
  • the lengths of the connector 6 and of the conduit 18 are provided such that the cup 14 projects laterally above the gun 1 while being disposed in a vertical plane very close to it so as not to unbalance the gun in use .
  • the mounting of the cup 14 on the connector 6 allows, before tightening the nut 25, to orient the inclination of the cup at will in a plane parallel to that of the gun, so, according to the position of use gun, on the one hand to permanently ensure a good supply of paint and, on the other hand, good balancing of the gun in the hand of the user.
  • the bucket 14 is then immobilized in this position by tightening the nut 25.
  • the gun has been shown in a position suitable for painting a horizontal surface, the bucket 14 then being inclined widely backwards allowing good flow of the paint by gravity out of the bucket and good balancing. of the spray gun whereas, in this position, a traditional gravity feed spray gun would be unbalanced forwards by the weight of the paint contained in the bucket.
  • the spray gun is shown in a position suitable for painting a vertical surface, the cup 14 then being in an intermediate position slightly inclined towards the rear, and in FIG. 6, the spray gun 1 is shown in a suitable position. to paint from below a surface inside, the bucket 14 then being in a very forward tilted position.
  • the position shown in FIG. 1 also corresponds to a position for laying the gun when it is not in use and it can then be seen that the cup 14 can advantageously be oriented so that the end of the leg d 'support 24 engages the support surface by constituting a stand which ensures stable positioning of the gun.
