A toy shooting range comprises a gun 3 having a trigger 24, a target 8 towards which the gun is directed, a striker pin 13 located behind the target 8, and a transmission interconnecting the trigger and the striker pin such that actuation of the trigger causes the striker pin to strike the target. In the construction shown the gun 3 is mounted on an upright arm 2 of an angle member 1, the horizontal arm of which comprises two parts 6, 7. The angle member 1 is suspended in gimbals 4 at the connection between the two parts. The part 7 carries pivotally at its end a lever 21 to which is attached an impact plate 20. The striker pin 13 is slidably guided under spring loading in a sleeve 14 secured to a carrier plate 16, the carrier plate being mounted on the part 7 for movement therewith. Movement of the sleeve and carrier plate assembly is limited by a frame 17 secured to a plate 18. The transmission includes a spring-loaded push rod 27 which co-operates with a latch 28 which in turn, in its cocked position, co-operates with a notch 30 in a spring-loaded actuating rod 29. The transmission is cocked manually by pulling a grip 40 rearwardly. On actuating the trigger the push rod 27 causes the latch 28 to rotate clockwise and disengage from the notch 30 to allow the actuating rod 29 to snap forward against the lever 21. The lever 21 and impact plate 20 then actuate the striker pin 13. In a further embodiment (Figs. 5, 6, not shown) the striker pin is attached to a spring loaded, pivotally mounted impact plate, the impact plate being actuated by a push rod. The transmission comprises a coupling link which co-operates with a face of the trigger at one end and is pivotally connected by a hook and eye connection to a spring loaded lever at the other. On actuation of the trigger the coupling link, lever and push rod are moved such that, at first, the pushrod moves away from the impact plate. On further movement an abutment face of the trigger engages the coupling link to disengage it from the trigger thus allowing the spring loading on the lever to urge the push rod against the impact plate thus causing perforation of the target.
