Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a toy gun (air soft gun/BB-gun) and more particularly, to a magazine for toy gun (air soft gun/BB-gun) that can be conveniently operated with less effort to guide loaded air soft gun/BB-gun bullets out of the bullet chamber into the bullet-feeding channel for feeding into the firing chamber for firing.
2. Description of the Related Art
FIGS. 1˜3 show a magazine for toy gun (air soft gun/BB-gun) according to the prior art. According to this design, the magazine comprises a housing formed of a first cover shell aa and a second cover shell bb and covered with shielding plates dd. The cover shells aa and bb each have an opening cc, and define therebetween a bullet chamber ee, a bullet loading entrance 10 at the top side of the bullet chamber 22, and a bullet-feeding channel 20. A spring-supported bullet stop 201 is adapted to close the exit of the bullet-feeding channel 20. An actuating wheel 30 and a main gear wheel 40 are concentrically provided at the inner side of the first cover shell aa corresponding to the bottom side of the opening cc of the first cover shell aa. The actuating wheel 30 has a plurality of teeth 301 equiangularly spaced around the periphery, and a spiral spring 302 mounted on the inside. An operating wheel 50 is provided outside the first cover shell aa, having a center shaft 501 inserted through the first cover shell aa and fastened to the inner end 3021 of the actuating wheel 30 and the center of the main gear wheel 40 (see FIGS. 1 and 3), and a series of teeth 502 arranged around the periphery and sloping in one direction. When assembled, the operating wheel 50 is suspended between the first cover shell aa and the respective shielding plate dd, having the series of teeth 502 partially extending out of the bottom side of the magazine for turning with the hand to drive the spiral spring 302, the actuating wheel 30, and the main gear wheel 40. A bullet guide roller 60 is pivotally mounted inside the first cover shell aa adjacent to the actuating wheel 30. A spring member 70 is provided inside the first cover shell aa, having one of the two end tips 701 thereof fastened to the bullet guide roller 60 and the other of the two end tips 701 extending out of the first cover shell aa and engaged with the teeth 502 of the operating wheel 50 to limit rotation of the operating wheel 50 to one direction. The second cover shell bb has a gear wheel chamber ff adapted to accommodate the main gear wheel 40, and an auxiliary gear wheel 80 pivotally provided above the gear wheel chamber ff and meshed with the main gear wheel 40 (see FIG. 3). An eccentric block 90 is pivotally provided adjacent to the auxiliary gear wheel 80, having a shaft 901, and a pinion 902 mounted on the shaft 901 and meshed with the auxiliary gear wheel 80. After loading of air soft gun/BB-gun bullets 100 into the bullet chamber ff, rotate the operating wheel 50 with the hand (see FIG. 4). At this time, the actuating wheel 30, the main gear wheel 40, the auxiliary gear wheel 80, the pinion 902, and the eccentric block 90 are rotated, and therefore air soft gun/BB-gun bullets 100 are guided out of the bullet chamber 22 into the bullet-feeding channel 20 by the bullet guide roller 701 and the actuating wheel 30 in proper order (see FIG. 9). Because the spiral spring 302 in the actuating wheel 30 is rolled up and then rotated with the actuating wheel 30 and the eccentric block 90 and because the eccentric block 9 is pivotally mounted in between the first cover shell aa and the second cover shell bb, air soft gun/BB-gun bullets 100 can be smoothly guided by the bullet guide roller 701 and the actuating wheel 30 out of the bullet chamber ee into the bullet-feeding channel 20 smoothly and will not be jammed in the magazine. When the spring-supported 201 is held pressed after attachment of the bullet-loaded magazine to the toy gun (air soft gun/BB-gun), air soft gun/BB-gun bullets 100 are moved out of the bullet-feeding channel 20 into the firing chamber of the toy gun in proper order for firing.
The aforesaid magazine for toy gun (air soft gun/BB-gun) is still not satisfactory in function. Because it requires much effort to rotate the operating wheel 50 with the hand, a young child may be unable to feed air soft gun/BB-gun bullets 100 to the bullet-feeding channel 20, or the teeth 502 may hurt the fingers or the fingers feel pain rotating the operating wheel 50.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 5˜7, a magazine for toy gun (air soft gun/BB-gun) in accordance with the present invention is shown comprising a first cover shell a and a second cover shell b. The first cover shell a and the second cover shell b are fastened together, thereby defining a bullet chamber C for accommodating air soft gun/BB-gun bullets 100, a bullet loading entrance 1 at the top side through which air soft gun/BB-gun bullets 100 are inserted into the bullet chamber C, and a bullet-feeding channel 2 through which air soft gun/BB-gun bullets 100 are delivered one after another into the firing chamber of the toy gun (air soft gun/BB-gun) for firing.
Referring to FIG. 8 and FIGS. 5˜7 again, a spring-supported bullet stop 21 is transversely inserted into the top side of the bullet-feeding channel 2 and normally maintained in a normal-close position to close the exit of the bullet-feeding channel 2. The spring-supported bullet stop 21 has a through hole 211. When the spring-supported bullet stop 21 is held pressed, the through hole 211 is maintained in alignment with the bullet-feeding channel 2 (see FIG. 6), for letting air soft gun/BB-gun bullets 100 pass out of the bullet-feeding channel 2 into the firing chamber of the toy gun for firing. A holder block 3 is provided inside the first cover shell a near the bottom, having a ratchet 31 at one side. An operating wheel 4 is provided in between the first cover shell a and the holder block 3, having a center shaft 41 inserted through the center of the ratchet 31, two pawls 42 engaged with the ratchet 31 to limit rotation of the operating wheel 4 relative to the holder block 3 to one direction, and a knob 43 perpendicularly extended from the back side thereof and extended through a through hole al of the first cover shell a to the outside for operation by the user. The knob 43 has two finger holes 431 for the insertion of the user's fingers to rotate the operating wheel 4, and a center plughole 432 into which a T-handle 433 can be plugged for enabling the user to rotate the operating wheel 4 with the T-handle 433 with less effort. An actuating wheel 5 and a main gear wheel 6 are respectively fastened to the center shaft 41 of the operating wheel 4 suspended between the holder block 3 and the second cover shell b for rotation with the operating wheel 4. The actuating wheel 5 has a plurality of teeth 51 equiangularly spaced around the periphery, and a spiral spring 52 mounted on the inside. The spiral spring 52 has an outer end (not shown) affixed to the inside wall of the actuating wheel 5, and the inner end 521 fastened to the center shaft 41 of the operating wheel 4. A bullet guide roller 7 is pivotally mounted on one side of the holder block 3 inside the first cover shell a. A spring member 71 is fastened to the inside of the first cover shell a, having an endpiece 711 fastened to the bullet guide roller 7 to support the bullet guide roller 7 in position, allowing the bullet guide roller 7 to be rotated within a limited angle. An eccentric block 8 is pivotally mounted in the first cover shell a adjacent to the bullet guide roller 7, having an eccentric shaft 81 and a pinion 82 provided at the top (free) end of the eccentric shaft 81. The second cover shell b has a gear accommodating chamber b1 corresponding to the main gear wheel 6, and an auxiliary gear wheel 9 pivotally mounted on the inside wall thereof and meshed between the pinion 82 and the main gear wheel 6 (see FIG. 6).
Referring to FIG. 9 and FIG. 8 again, after loading of air soft gun/BB-gun bullets 100 into the bullet chamber C, drive the knob 43 to rotate the actuating wheel 5, the spiral spring 52, the main gear wheel 6, the auxiliary gear wheel 9, the pinion 82, and the eccentric block 8, thereby causing the bullet guide roller 7 and the actuating wheel 5 to guide air soft gun/BB-gun bullets 100 out of the bullet chamber C into the bullet-feeding channel 2 one after another in proper order (see FIG. 9). Because the spiral spring 52 in the actuating wheel 5 is rolled up and then rotated with the actuating wheel 5 and the eccentric block 8 and because the eccentric block 8 is pivotally mounted inside the first cover shell a, air soft gun/BB-gun bullets 100 can be smoothly guided by the bullet guide roller 7 and the actuating wheel 5 out of the bullet chamber C into the bullet-feeding channel 2 smoothly and will not be jammed in the magazine. When the spring-supported bullet stop 21 is held pressed after attachment of the bullet-loaded magazine to the toy gun (air soft gun/BB-gun), air soft gun/BB-gun bullets 100 are moved out of the bullet-feeding channel 2 into the firing chamber of the toy gun in proper order for firing.
As indicated above, the invention uses the knob 4 for rotating the actuating wheel 5 with the fingers with to guide air soft gun/BB-gun bullets 100 out of the bullet chamber C into the bullet-feeding channel 2 smoothly. Therefore, either a young child or adjust can operate the toy gun safely with less effort to guide loaded air soft gun/BB-gun bullets 100 into the bullet-feeding channel 2 for feeding into the firing chamber for firing. And the operator's fingers feel no pain.
A prototype of magazine for toy gun has been constructed with the features of FIGS. 5˜9. The magazine for toy gun functions smoothly to provide all of the features discussed earlier.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
