Abstract

A paint bullet feeder for a paint ball gun includes a cartridge, a vibration means mounted within the cartridge, and a resilient means for absorbing vibration to the cartridge, whereby bullets can be smoothly fed to a gun without influencing the aiming of the gun

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention is related to a bullet feeder for paint ball guns and in particular to one which can feed bullets smoothly into a gun without influencing aiming of the gun.

2. Description of the Prior Art

As shown in FIG. 1, the conventional paint bullet gun 10 is provided with a seat 11 at the top for receiving a funnel-shaped outlet 22 of a cartridge 20. The upper portion of the cartridge 20 is provided with a cover from which paint bullets 50 can be filled into the cartridge 20. However, the paint balls 50 will often jam when moving down the funnel-shaped outlet 22, due to too many balls moving down the outlet 22 simultaneously. This drawback makes it impossible for the user to fire the paint bullet continuously and this jamming situation is very common in conventional paint bullet guns.

Therefore, it is an object of the present invention to provide a paint bullet feeder for a paint ball gun which can obviate and mitigate the above-mentioned drawbacks.

SUMMARY OF THE INVENTION

This invention is related to an improvement in the structure of a paint bullet feeder for paint ball guns.

It is the primary object of the present invention to provide a paint bullet feeder for paint ball guns which can feed bullets into a gun smoothly without influencing the aiming of the gun

It is another object of the present invention to provide a paint bullet feeder for paint ball guns which is simple in construction.

The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates. [0014]
With reference to the drawings and in particular to FIGS. 2 and 3 thereof, the paint bullet feeder for a paint ball gun according to the present invention generally comprises a [0015] cartridge 20 with an inlet provided with a lid 21. The cartridge 20 has an outlet 22 at the bottom adapted to connect to a gun. The upper portion of the cartridge 20 is provided with a battery chamber 23 engageable with a cover 25. A battery 24 is fitted inside the battery chamber 23. A recess 26 is formed on the top of the cartridge 20 for receiving a switch 27 which is electrically connected with the battery 24. A seat 28 is formed on the inner top side of the cartridge 20 for mounting an upper end of a spring 32. A flexible tube 33 is fitted within the spring 32. A conical member 31 composed of two half portions has an upper end engaged with the lower end of the spring 32. A vibration motor 30 is fitted within the conical member 31 and has connecting wires extending through the flexible tube 33 to connect with the switch 27. The vibration motor 30 has a downwardly extending output shaft on which is eccentrically mounted a cam 32, so that when the switch 27 is turned on, the vibration motor 30 will vibrate thereby causing the conical member 31 to vibrate.
Referring to FIG. 4, the [0016] conical member 31 is suspended within the cartridge 20 by the spring 33 and positioned right above the outlet 22. When the switch 27 is turned on, the cam 32 will rotate thereby causing the vibration motor 30 to vibrate and therefore vibrating the conical member 31. As a consequence, the bullets 15 will be subject to vibration so that the bullets 15 will fall down into the outlet 22 in order. Meanwhile, the vibration of the vibration motor 30 will be absorbed by the spring 32 thereby preventing the gun from oscillating so that the aiming of the gun will not be influenced.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. [0017]
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
