Paint ball feeding buffer device
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.
a) Field of the Invention
The present invention relates to a paint ball feeding buffer device, and more particularly to a magazine which is used in a paint-ball gun to load a plurality of paint balls, and is provided with a roll-up device having a damping member to buffer an advancing device, so as to stably release a thrust in an advancing process such that the paint balls can be rammed smoothly.
b) Description of the Prior Art
To allow a paint-ball gun to emulate a real gun and to fire continuously, a magazine which can load a plurality of paint balls is used. The magazine is accessed below a gun to form a necessary design for emulation and firing continuously. The paint ball is normally a plastic polymer enclosing a dye, and its material can be deformed or broken when being squeezed by an external force, such that when hitting on a human body, the human body can be prevented from being harmed and a point of impact can be determined by a colored powder. Therefore, a shell of the paint ball is made by a non-hard material, and the paint ball will be easily deformed when being squeezed by the external force. The paint balls of an ordinary paint-ball gun are fed from a funnel located above a bore and into the bore by gravity, so as to maintain roundness by loading the paint balls into the bore from free falling.
However, as the funnel is located above the bore, the emulation is lost. Accordingly, recently there is an emulated magazine which is latched below the gun to form the emulation, and can load a plurality of paint balls for firing continuously.
An ordinary magazine is shown in
The advancing device 40 is arranged in a linear path of the loading chamber 5, and includes a toggle spring 4, an interior of which is sheathed with a pull string 41. A free end of the pull string 41 is connected with a pushing head 42, an end of the toggle spring 4 operates on the pushing head 42, and the other end is abutted at a corner close to a roll-up device 3. The roll-up device 3 is located at a rear end of the advancing device 40, and can roll up the pull string 41 to resist a tension of the toggle spring 4 to pull back the pushing head 42 indirectly. In this process, the toggle spring 4 is compressed, and the pushing head 42 is pulled rearwards by the roll-up device 3 to empty the loading chamber 5, thereby loading a plurality of paint balls by free falling.
Referring to
At an instant moment that the release button 342 is released, stored energy of the spring which is compressed will be released instantly. That instant pressure will at least compress a neighboring paint ball 100A, and that paint ball 100A will be deformed easily. After it is deformed, the paint ball 100A will be expanded radially to rub at a corresponding inner chamber surface of the loading chamber 5 to form a blockage. Therefore, an agility for pushing the paint balls outwards will be lost.
Furthermore, if the expansion force of the toggle spring 4 is even bigger, then in addition to the aforementioned shortcoming, it is possible that all of the nearby paint balls will be deformed, thereby forming a more severe blockage that prevents from pushing the paint balls.
In addition, before the cartridge 1 enters into a barrel, if the release button 342 is touched mistakenly by an external force, then the toggle spring 4 will be released instantly, the outlet will not be restricted at all, and all of the paint balls will be forced out instantly.
Referring to
For the prior art, at an instant moment that the release button 342 is released, the pull string 41 will be quickly moved out momentarily, as shown in
The abovementioned is an ordinary design of a paint ball magazine, which will compress the paint balls to change their appearances, and form the blockage condition, accordingly.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide a paint ball feeding buffer device utilizing a damping member located in a roll-up device, to form a damping function to a free rotating speed of a winding wheel or a shaft, thereby prohibiting a pushing head from forming a momentary pressure to a neighboring paint ball.
Another object of the present invention is to provide a paint ball feeding buffer device having a damping member, which is a ring and can be located at a side of a winding wheel or a ratchet opposite to a roll-up seat, so as to form a friction to result in a damping function.
A third object of the present invention is to provide a paint ball feeding buffer device having a damping member which can be located directly between a seat and a shaft, to slow down a rotating speed of the shaft by rubbing on a surface of the shaft with a radial force.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.
Referring to
At an end surface of the winding wheel 31 or the ratchet 32 is disposed with a damping member 6 which is elastic and results in compression through a locking force by connecting the shaft 61 and the cross-over plates 30A, 30B. After compression, one tension operates at a direction on an opposite surface of the winding wheel 31, and the other tension operates on an opposite side of the seat 30 or the cross-over plates 30A, 30B. The two tensions are back to back, and point toward the winding wheel 31, to damp a rotating speed of the winding wheel 31. By that damping function, at an instant moment that a release button 342 (as shown in
The damping member 6 can be a ring, with its inner diameter crossing over an outer diameter of the shaft 61, and rub on a side surface of an opposite end of the winding wheel 31 or the ratchet 32 (as shown in
The damping member 6 is located at an end surface of the winding wheel 31, opposite to a surface of the cross-over plate 30B. After locking by the locking member 610, an indirect damping function will be formed between the end surface of the winding wheel 31 and the opposite surface of the cross-over plate 30B, to reduce a rotating speed of the winding wheel 31, thereby acquiring the damping effect. A tightening force of the locking member 610 can change a locking force with which the cross-over plate 30B compresses the damping member 6, and when the winding wheel 31 is tightly locked, the rotating speed of the winding wheel 31 can be controlled significantly slowly. In addition, a friction force formed by the damping member 6 should be smaller than an expansion force of the toggle spring 4.
The aforementioned damping member 6 can be disposed at the opposite surface of the winding wheel 31 and the cross-over plate 30B, or the opposite surface of the ratchet 32 and the cross-over plate 30A. By a locking force along an axis of the shaft 61 and the locking member 610, the damping member 6 is compressed to form an elastic compression friction force.
