Paint ball feeding buffer device

Abstract

A paint ball feeding buffer device, especially used for a paint-ball gun, is a magazine which loads a plurality of paint balls and provides for firing continuously. The magazine includes a roll-up device which restricts a stroke of an elastic advancing device, and the roll-up device is provided with a damping device which allows an initial stroke of the advancing device to be buffered, so as to prevent the paint balls from being squeezed, deformed, and ejected, by pressure which is released instantly.

What is claimed is: 
     
         1 . A paint ball feeding buffer device, especially a buffer device which forms a damping effect to an elastic advancing device in a paint-ball magazine, comprising a cartridge, with a connector disposed at an outlet; a U-shape loading chamber for loading a plurality of paint balls; an advancing device which is distributed along a linear path of the loading chamber by a pull string, with a free end of the pull string being assembled with a pushing head, a path of the pull string being provided with a toggle spring, an end of the spring expanding the pushing head, and the other end being abutted at a rear end of the loading chamber; a roll-up device, which is provided with a winding wheel connected at the other end of the pull string to resist an expansion force of the toggle spring and to pull and release the pushing head through the pull string, with the winding wheel being provided with a toggle rod to restrict a rolling and releasing of the winding wheel; the roll-up device further including a damping member to restrict a rotating speed of the winding wheel. 
     
     
         2 . The paint ball feeding buffer device according to  claim 1 , wherein the roll-up device further includes an inverted U-shape roll-up seat, two sides of which are extended with cross-over plates, each having a through-hole; the winding wheel and a ratchet being pivoted by a shaft and a locking member, and the damping member being located between inner sides of the cross-over plates. 
     
     
         3 . The paint ball feeding buffer device according to  claim 1 , wherein a damping size of the damping member is adjusted by the locking member. 
     
     
         4 . The paint ball feeding buffer device according to  claim 1 , wherein the damping member is a ring of an elastic body, and is coaxially located at an end of the winding wheel. 
     
     
         5 . The paint ball feeding buffer device according to  claim 2 , wherein the damping member is a ring of an elastic body, and is coaxially located at an end of the winding wheel. 
     
     
         6 . The paint ball feeding buffer device according to  claim 1 , wherein the damping member is a ring of an elastic body, and is coaxially located at an end of the ratchet. 
     
     
         7 . The paint ball feeding buffer device according to  claim 2 , wherein the damping member is a ring of an elastic body, and is coaxially located at an end of the ratchet. 
     
     
         8 . The paint ball feeding buffer device according to  claim 1 , wherein the roll-up device further includes an inverted U-shape roll-up seat, two sides of which are extended with the cross-over plates, each having a through-hole; the winding wheel and the ratchet being pivoted by the shaft and the locking member, the damping member being in a ring shape and located on a pivot between the shaft and the cross-over plate, and an inner ring surface of the damping member operating on an outer circumference of the shaft.
