Publication number: 20110146647Abstract: A toy gun gas intake control mechanism includes a holder frame, an impact member having an elongated pivoted with its bottom end to the holder frame, a striking block, a pivot axle that pivotally connects the striking block to the top end of the elongated base and a spring member for revering the striking block, a retaining block supported on a spring member in the holder frame and having a retaining notch for retaining the outer end of the pivot axle. When firing a bullet, the bolt body of the toy gun moves forwards, the striking block strikes a seal member to open a gas inlet, and the pivot axle is moved out of the retaining notch of the retaining block for allowing upward displacement of the retaining block. When the bolt body moves backward after firing, the retaining block is forced downwards to the inside or the holder frame by the bolt body, the outer end of the pivot axle is engaged into the retaining notch, and the striking block is returned, causing the seal member to close the gas inlet again.Type: ApplicationFiled: December 22, 2009Publication date: June 23, 2011Inventor: Shih-Che Hu

Patent number: 7878106Abstract: A firing control mechanism for an air-soft toy gun is disclosed for enabling a user to rotate a switch in selecting a single shot, 3-shot continuous firing, multi-shot continuous firing or safety lock mode, having a ratchet wheel pivotally mounted on an axle of the hammer thereof, which ratchet having two shadow teeth and one deep tooth arranged in a series around the periphery at one side and sloping teeth arranged around the periphery at an opposite side. The hammer has a stop rod meshed with one sloping tooth of the ratchet wheel. During a continuous 3-shot firing action, the ratchet wheel is rotated following down stroke of the hammer, and a pawl is meshed with one shadow tooth or the deep tooth, and the stop rod of the hammer is shifted into mesh with a next sloping tooth of the ratchet wheel to prohibit reverse rotation of the ratchet wheel when the hammer is returned after a firing action.Type: GrantFiled: April 21, 2009Date of Patent: February 1, 2011Inventor: Shih-Che Hu
