Definitions

  • the invention relates to an improvement for a hand-held foam applicator or "gun” for producing foam, more particularly one component polyurethane foam.
  • Such applicator comprises typically a handgrip, a body, a steel barrel with a nozzle tip, an adaptor or fitting for attaching a can - also called a "basket” , and a needle assembly comprising a pressure spring with one end obturating the nozzzle tip and being drawn back via a trigger arrangement for delivery of the foam from the can through the barrel and the nozzle.
  • This F-adapter is a standard basket, but without non return ball.
  • the opening-closing of this system is regulated by a ball valve.
  • the distance between the ball valve and the opening of the can in the F-adapter is very important because foam can cure out.
  • the system would be better when the distance is as small as possible. This means that the stem of a valve should almost "touch" the ball valve.
  • This system of the prior art is called the Ball Valve Basket.
  • An object of the invention is to provide a new closing system for the basket in a dispensing gun to prevent such accident.
  • the arrangement allows the costumer to turn on the ball valve only when there is a can on the gun. This can be filled with either PU-foam or PU-cleaner.
  • a further object of the invention is to provide an automatic system closing a ball valve when no can is affixed to the gun.
  • Fig. 5 shows a complete assembly accordinging to the invention.
  • a can 5 with a ring 6 to be screwed or clamped in a basket 3.
  • the gun has a trigger 7 for moving a needle (not shown) and closing/opening the nozzle 8.
  • a safety member 9 in the form of a drawer that can be pushed or slided under the basket on one side, (here away from the barrel 14 side, the front side) against a spring. When released, due to the biasing action of the spring, the member 9 will come back at its initial position in the absence of a can.
  • the vertically extending part will contact or engage the ring-can assembly 5, 6 in a blocking or locking arrangement so that the safety member is immobilized in a particular position and biased by the spring.
  • a handle's axle traversing the safety member through a specifically enlarged portion 12 of a longitudinal slot 10 provided lateraly on this member 9 will be able to rotate by 90° and therefore to open the inlet passage.
  • the handle cannot rotate because the highest dimension of the cross-section of its axle 11 does not permit rotation in a non-enlarged part of the slot 10.
  • FIG. 6 is a detailed view showing the enlarged section 12 of the slot 10 and the axle 11 in the open position. The largest cross-sectional dimension of the axle is then vertical.
  • FIG. 8 it is shown in a more detailed way that the safety member 9 can slide under the basket 3 under the influence of the Push button 13, the handle remaining fixed relative to the adapter 3 and the body of the gun.
  • FIG. 9 is a part view from bottom illustrating the ring biasing the safety drawer so that at rest the latter is in a closing configuration.
  • the safety system 9 springs back towards the front of the gun. This is caused by the metal spring 16 on the bottom of the system. In this position it is impossible to open the ball valve because the safety is not in the right position.
  • FIG. 12 another embodiment of the invention is illustrated.
  • the ball valve opens automatically when the can is screwed on the gun's adapter.
  • the teethed partial disk 20 engages a transverse rotating member and pivot itself about the pivot 22 of a ball valve.
  • the rotating member 21 is driven by the screwing of the can + ring on the gun's adapter.
  • FIG. 13 The only difference is the can handle 1.
  • the handle is causing the sliding of the safety member 9.
  • the safety memeber in the other position.
  • this is achieved not by using a push button 13 (by hand) as in the previous design, but preferably by pushing, then releasing, the can 10 against the can handle 30 during the process of attaching the can to the gun.
