Definitions

  • the present invention relates to a delivery gun, which has been specifically designed for delivering polyurethane to which a propelling and foaming gas has been added.
  • a delivery gun is conventionally used, which allows to deliver or meter the polyurethane material held in a holding vessel together with the foaming gas.
  • the product, exiting the gun in the form of a foam, can be used and applied in an adjustable manner.
  • Prior polyurethane delivery guns comprise a gun body, to which a polyurethane bottle can be coupled, which communicated with the inside of a tubular element perforated at its free end portions and therethrough a sliding rod is caused to pass.
  • the mentioned rod is provided with a conical end portion, adapted to plug or shut-off the perforated end portion, also conical, of the mentioned tubular element.
  • the rod displacement amount controls the size variation of the annular opening and, accordingly, the delivered polyurethane amount.
  • an operator can, by operating a trigger lever, coupled to the rod, easily adjust the delivered or metered polyurethane amount.
  • the delivery gun comprises a bottom element which can be screw coupled to the body of the gun, thereby, by screwing on or off said bottom element, the position of the latter with respect to the gun body can be easily adjusted, thereby also adjusting the limit of stroke position of the rod.
  • the aim of the present invention is to provide such a delivery or metering gun, allowing to overcome the above mentioned drawbacks.
  • a main object of the present invention is to provide such a delivery gun including an improved system for adjusting the limit of stroke position of the rod thereof.
  • Another object of the present invention is to provide such a delivery or metering gun, in which the bottom element is not screw engaged.
  • a delivery gun specifically designed for delivering foamed polyurethane, comprising a gun body, including a delivery tubular element, communicating with a material to be delivered vessel, and adapted to be coupled to said body, a sliding rod longitudinally sliding in said tubular element and having a conical end portion for engaging a delivery opening, said rod being adapted to disengage said opening during a backward movement thereof, the stroke of said rod being limited by end of stroke limit means and being characterized in that said end of stroke limit means comprise a rotary element, coupled to said body, and adapted to be driven from the outside, said rotary element being kinematically coupled to an abutment element, slidable with respect to said body, due to the rotary movement of said rotary element, and adapted to define the rear limit of stroke position of said rod.
  • the delivery gun comprises a gun body 2 provided with a fitting 3 for a vessel 4 adapted to hold therein a material to be delivered or metered, for example a polyurethane and foaming gas bottle.
  • an extension element 5 can be coupled, said extension element comprising a tubular element including a free end portion with a delivery opening 6 having a conical longitudinal cross-section.
  • the inner cavity of the tubular element 5 is coupled to the vessel 4 through a duct 8, thereby the material to be delivered can pass to the delivery opening 6 to be metered or delivered.
  • a delivery rod 7 is arranged in the cavity of the tubular element 5 and can longitudinally slide therein.
  • said rod 7 has a conical front end portion, for shutting-off the delivery opening 6 in its closure position and, by backward sliding, being adapted to adjustably open the delivery opening 6, due to the tapering or conicity of said rod.
  • the back sliding of the rod 7 is controlled by an operating or driving lever 9, coupled to the gun body 2 and which can be manually operated by the user, gripping the delivery gun by a gun grip portion 10.
  • the rear end portion 11 of the rod 7 is adapted to engage in a blind hole 13 of an abutment element 12, which can slide in the gun body 2.
  • An annular recess 14 of the abutment element 12 is adapted to receive therein an end portion of a coil spring 15 coaxial with the rod 7 and having the other end portion thereof abutting against a flange 16 of the rod 7.
  • the abutment element 12 can slide in the gun body 2, but it cannot turn about its longitudinal axis, through guides 17 formed in the gun body 2 and is provided with a threaded portion 18, adapted to engage a ring-nut 20 formed in a rotary element 19.
  • the latter comprises a bottom element, on the outside of the gun body 2, and which can be turned or rotated by the operator in order to axially drive or displace the abutment element 12 thereby adjusting the end of stroke position of the rod 7.
  • the rotary element 19, in particular, can be snap assembled on the gun body 2, to be able of rotating, without disengaging or longitudinally moving.
  • the operation of the delivery gun according to the present invention would be very simple.
  • the maximum amount of product which can be delivered or metered will depend on the end of stroke position of the rod 7, which can be easily adjusted by turning the rotary element 19.
  • the latter can comprise signalling elements for signalling the end of stroke or limit position, such as notches or other indicating marks, allowing a user to easily detect the position of the adjusting element.
  • the invention fully achieves the intended aim and objects, since the subject delivery gun can be easily adjusted by a bottom element for adjusting the maximum delivered amount, said bottom element turning with respect to the gun body, without threading on or off.
