ABSTRACT:
An air-pulse powered arrow shooting toy set provided with at least one soft arrow whose shaft is formed of resilient, flexible foam material, the rear section of the shaft having an axial bore so that the arrow is slidable onto a launching tube which then extends into the bore. Coupled to the tube is an air gun which, when cocked and then fired, produces a compressed air pulse which is delivered to the launching tube to shoot off the arrow. The air gun includes a barrel having a piston slidable therein which is attached to a piston rod that extends out of one end of the barrel to join a handle. Surrounding the piston rod between the one end of the barrel and the piston is a compressible helical spring. A hand grip attached to the barrel is provided with a spring-biased trigger having a latching finger which when the trigger is inactive extends into a slot in the barrel. In operation, the player first pulls the handle to cause the piston to advance toward the one end of the barrel until it is engaged and latched by the latching finger, the spring then being compressed and the gun being cocked. To fire the gun, the player actuates the trigger to unlatch the piston which then is driven by the expanding spring toward the other end of the barrel to produce a compressed air pulse that is delivered to the launching tube.
