Definitions

  • the present invention relates to an air gun or pistol having the control valve housed within a threaded fitting or "nipple" communicating with the compressed air pipe.
  • the air guns hitherto adopted for a number of various utilizations although generally classifiable as of blowing, washing and inflating type, all show the control valve housed in a gun body so shaped as to form a longitudinal passage therein for the air fed through a threaded end fitting or "nipple", and transverse passages for housing and controlling a valve having a body designed to obstruct said longitudinal passage.
  • the lever for the control of valve opening is positioned in the low front portion of the gun, like in the weapon from which this device takes its name by analogy.
  • the foregoing structure involves some known drawbacks of the compressed air pistols, among which a remarkably complicated construction of the gun body with consequently high costs caused by the difficulty of obtaining mutually transverse, inner holes by moulding, as well as by the high number of members forming the valve drive to supply the valve with the movement of the control lever.
  • the valve should be mounted within the gun body at the same time while the latter is assembled, thus giving rise to a heavy utilization of labour due to the time required, as well as strong difficulties, or even unfeasibility in case of valve replacement.
  • the object of the invention is to provide an improved air gun body in which the valve is housed within the inlet fitting itself, the lever controlling its opening is placed in the upper portion of the gun and the drive for its operation is simply comprised of an elongated small rod which extends longitudinally inside the gun body.
  • the gun body has a simplified construction as it can be simply obtained by moulding due to the fact that there are provided no transverse holes, and the valve is suitable to be mounted separately therein with a consequent appreciable reduction of the time required in assembling and a good practical feasibility in replacement.
  • the particular positioning of the control lever allows to hold the gun with four fingers while operating the lever by means of the thumb. Therefore a better ease of handling the gun is afforded, especially if it is of the washing type, as well as a greater efficiency of the action exerted on the lever itself, whereby a lower muscular effort is required to the operator in order to depress the lever for opening the valve.
  • the gun body 1 shows, as it is known, a longitudinal hollow 10 as a passage for the compressed air flowing from a feed conduit 9 connected therewith by means of a threaded fitting or "nipple" 6.
  • valve 3 is housed within said passage 10 and operates coaxially therewith, having its valve body or sealing cone 5 housed inside the "nipple" 6 itself.
  • a small drive rod 3a communicates said sealing cone with a control lever 2 located at the upper portion of the gun body 1, with a pivot point 2a on the front part of the body itself, thus forming a second class lever wherein the active force is applied onto the end of lever 2 which is opposite the pivot 2a and the resisting force is exerted at an intermediate point by the end of rod 3a opposite to the sealing cone 5.
  • said spring means is a spiral spring 4 which is co-axial with the rod 3a along a length thereof at the valve body end, opposite to the end engaging lever 2.
  • valve body 5 has been represented in a preferred "double cone" embodiment, i.e. symmetrical to a transversal plane, so as to be suitable to be applied without difficulty in both directions with a consequent further reduction of the assembling time. It may be made hollow to be fixed to the end of rod 3a which has been shown with a reduced cross-section in the drawing and can retain the member 5 such as by means of a nut or rivet 8.
  • the gun body 1 can be easily obtained by moulding as it does not show hollow parts having a perpendicular direction to the main longitudinal passage 10 of air and the valve control is greatly simplified both for its assembly and for the body moulding there being required no additional cavities to house the drive members for giving movement from the lever to the valve. It appears also clear a better gripping and handling of the pistol itself which can be operated with only the user's thumb on the lever 2 while the other four fingers can be firmly positioned around the gun body 1.
  • valve body 5 could have a different shape from the one illustrated and be fixed to the rod 3a by a different means without exceeding the scope of the present invention.
