Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a compressed gas gun device or a paint bullet gun, and more particularly to a compressed gas gun device having an improved projectile feeding tube for attaching magazines or receptacles of various shapes or sizes or diameters thereto.

[0003] 2. Description of the Prior Art

[0004] Typical compressed gas guns comprise a gun body, a stock, a trigger, a bullet loading guide, and a sight rack, in which the bullet loading guide is secured onto the upper gun barrel, for supplying projectiles or bullets into the gun barrel one at a time. Normally, a compressed air reservoir is coupled to the stock or handle portion of the gas gun, for supplying compressed air to force or to shoot the projectiles or bullets out of the gun barrel.

[0005] For example, U.S. Pat. No. 6,347,622 to Hsuch discloses one of the typical compressed gas guns comprising an upper gun barrel provided on top of a gun body, and one or more bullet loading guides selectively attachable to the gun barrel. For example, the receptacle provided on the bullet loading guide may be perpendicularly extended up from the bullet loading guide, or may be obliquely extended from the bullet loading guide at 45.degree. angle or elevation.

[0006] However, the receptacles are solidly fixed and provided on the bullet loading guide, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters may not be suitably attached to the bullet loading guide.

[0007] U.S. Pat. No. 6,408,835 to Ming-Hsien discloses another typical compressed gas gun comprising an upper gun barrel provided on top of a gun body, and a bullet feeding device detachably or selectively attachable to the gun barrel. However, similarly, the feeding tubes of the bullet feeding device are also solidly fixed and provided on the bullet feeding device, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters also may not be suitably attached to the bullet feeding device.

[0008] U.S. Pat. No. 6,553,983 to Li discloses a further typical compressed gas gun comprising an upper gun barrel provided on top of a gun body, and a ball feeding tube solidly provided and fixed or attached to the gun barrel. However, similarly, the ball feeding tube is also solidly fixed and provided on the gun body or the gun barrel, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters also may not be suitably attached to the bullet feeding device.

[0009] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional compressed gas guns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0024] Referring to the drawings, and initially to FIGS. 1-5, a compressed gas gun device 1 in accordance with the present invention comprises a gun body or housing 10, a gun barrel 11 formed or provided on top or in front of the housing 10, a stock or handle portion 12 provided or attached to bottom of the housing 10, and having a trigger 13 for triggering or operating the gas gun device 1.

[0025] The housing 10 includes a port or coupler 20 coupled to a hose 21, for coupling to a compressed air reservoir, such as a compressed air tank (not shown) which may supply compressed air into the inner chamber 14 of the housing 10 or the gun barrel 11 (FIG. 3), in order to force or to shoot the projectiles or bullets out of the gun barrel 11. The above-described structure is typical and will not be described in further details.

[0026] The housing 10 further includes an opening 15 formed and provided on top of the housing 10 or the gun barrel 11 (FIG. 3), and defined by two lower side flanges 16, and two end or a front edge 17 and a rear edge 17, it is preferable that each of the end or front and rear edges 17 includes a notch 18 formed therein, also best shown in FIG. 3.

[0027] A projectile feeding tube 30 includes a lower portion 31 engaged or seated within the opening 15 of the housing 10 or the gun barrel 11, and engageable with the side flanges 16 and the end or front and rear edges 17 of the housing 10, and includes one or more, such as two projections 32 extended from the lower portion 31 thereof, for engaging into the notches 18 of the end or front and rear edges 17 of the housing 10 or the gun barrel 11, and secured to the housing 10 or the gun barrel 11 with one or more fasteners 19 or latches or the like.

[0028] For example, the latches or the fasteners 19 may be attached or threaded or secured to the end or front and rear edges 17 of the housing 10 or the gun barrel 11, and may be engaged with the projections 32 of the projectile feeding tube 30, in order to detachably secure the projectile feeding tube 30 to the housing 10 or the gun barrel 11.

[0029] The projectile feeding tube 30 includes a bore 33 formed therein, and an inclined surface 34 formed in the upper portion thereof, and includes an outer thread 35 formed or provided thereon. The engagements of the projections 32 of the projectile feeding tube 30 in the notches 18 of the housing 10 may anchor the projectile feeding tube 30 to the housing 10, and may prevent the projectile feeding tube 30 from being rotated relative to the housing 10.

[0030] A ring or sleeve 43 is engaged into the bore 33 of the projectile feeding tube 30, and includes an inclined surface 44 (FIGS. 2, 4) engaged with the inclined surface 34 of the projectile feeding tube 30, best shown in FIGS. 5-10, for allowing the sleeve 43 to be easily engaged into the bore 33 of the projectile feeding tube 30 by the sliding engagement of the inclined surfaces 34, 44 of the projectile feeding tube 30 and the sleeve 43.

[0031] A magazine or receptacle 40 is provided for receiving paint bullets or projectiles therein, and includes a pipe 41 extended downwardly therefrom, and engageable into the sleeve 43, such that the sleeve 43 will be engaged between the pipe 41 of the magazine or receptacle 40 and the projectile feeding tube 30. It is preferable that the sleeve 43 includes a knurled inner peripheral surface 45 for frictionally engaging with the pipe 41, and an inclined slit 46 formed therein, to increase a resilience of the sleeve 43.

[0032] A control ferrule 37 includes an inner thread 38 formed therein, for threading with the outer thread 35 of the projectile feeding tube 30 (FIGS. 5-10), and for solidly securing the pipe 41 of the magazine or receptacle 40 to the projectile feeding tube 30. The control ferrule 37 further includes an inner peripheral flange 39 formed thereon, and extended radially and inwardly therefrom, for engaging with the sleeve 43, and for forcing the sleeve 43 into the bore 33 of the projectile feeding tube 30.

[0033] For example, as shown in FIGS. 5 and 6, before the control ferrule 37 is tightly threaded with the outer thread 35 of the projectile feeding tube 30, the sleeve 43 has not been forced into the bore 33 of the projectile feeding tube 30, such that the pipes 41 of the receptacles 40 of various shapes or sizes or diameters may be engaged into the bore 33 of the projectile feeding tube 30.

[0034] As shown in FIGS. 7-10, when the control ferrule 37 is further rotated or tightly threaded with the outer thread 35 of the projectile feeding tube 30, the sleeve 43 may be forced to further or to deeply engage into the bore 33 of the projectile feeding tube 30 by the inner peripheral flange 39 of the control ferrule 37, and thus to allow the sleeve 43 to be solidly engaged and secured between the pipe 41 of the magazine or receptacle 40 and the projectile feeding tube 30, due to the sliding engagement of the inclined surfaces 34, 44 of the projectile feeding tube 30 and the sleeve 43, and such that the pipes 41 of the receptacles 40 of various sizes or diameters may be solidly secured to the projectile feeding tube 30.

[0035] It is to be noted that the other projectile feeding tubes 30 having bores 33 of different inner diameters may also be selectively or changeably secured to the housing 10 or the gun barrel 11, for allowing the other pipes 41 of the receptacles 40 of various sizes or diameters to be selectively or changeably secured to the projectile feeding tube 30.

[0036] Accordingly, the compressed gas gun device in accordance with the present invention includes an improved projectile feeding tube for attaching magazines or receptacles of various shapes or sizes or diameters thereto.

[0037] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
