Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a rotating-force adjusting device, and more particularly to a rotating-force adjusting device for a toy gun that can be used to adjust a rotating force of a pellet that is mounted in the toy gun.

2. Description of Related Art

A conventional toy gun has a gun body and a mounting tube. The mounting tube is hollow, is mounted in the gun body and has an inlet end, an ejecting end, an internal surface and a pressing block. The pressing block is formed on and protrudes from the internal surface of the mounting tube and has a thickness, a first end and a second end. The first end of the pressing block is formed at the inlet end of the mounting tube, and the second end of the pressing block is formed at the ejecting end of the mounting tube. The thickness of the pressing block is gradually thickened from the first end to the second end of the pressing block. When a pellet mounted in the gun body is ejected out of the conventional toy gun, the thickness difference of the pressing block from the first end to the second end of the pressing block can provide a pressing pressure to the pellet, and this can provide a rotating force to the pellet to increase the ejection stroke of the pellet.

However, the pressing block of the mounting tube of the conventional toy gun can only provide a single pressing pressure to the pellet, and the pellet can only be ejected by the conventional toy gun with a specific rotating force and a specific stroke. Then, a user cannot adjust the rotating force and the range of the pellet of the conventional toy gun according to the user's need.

To overcome the shortcomings, the present invention provides a rotating-force adjusting device for a toy gun to mitigate or obviate the aforementioned problems.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 to 3, a rotating-force adjusting device for a toy gun in accordance with the present invention comprises a gun body 40, a mounting tube 10, a driven element 20 and a driving element 30.

The gun body 40 has an outer shell, an outer barrel 43 and an inner barrel 44.

The outer shell is composed by two half-shells that are respectively a first half-shell 41 and a second half-shell 42. With reference to FIGS. 2 and 5, the first half-shell 41 has a mounting segment, a barrel segment, an internal surface, a positioning recess 45 and a holding recess 46. The positioning recess 45 is formed in the internal surface of the first half-shell 41 at the mounting segment of the first half-shell 41. The holding recess 46 is formed in the internal surface of the first half-shell 41 at the mounting segment of the first half-shell 41 between the positioning recess 45 and the barrel segment of the first half-shell 41.

The second half-shell 42 is detachably connected to the first half-shell 41 and has a barrel segment, a mounting segment, an internal surface, an external surface and an adjusting slot 47. The barrel segment of the second half-shell 42 is connected to the barrel segment of the first half-shell 41. The mounting segment of the second half-shell 42 is connected to the mounting segment of the first half-shell 41. The adjusting slot 47 is elongated, is formed through the internal surface and the external surface of the second half-shell 42 at the mounting segment of the second half-shell 42, and the adjusting slot 47 has an upper end, a lower end and multiple engaging teeth 471. With reference to FIGS. 2 and 5, the engaging teeth 471 are formed on and protruding from the internal surface of the second half-shell 42 beside the adjusting slot 47.

The outer barrel 43 is mounted around the barrel segments of the half-shells 41, 42 and abuts the mounting segments of the half-shells 41, 42.

The inner barrel 44 is mounted in the outer barrel 43 and has an inner end extending to the mounting segments of the half-shells 41, 42.

With reference to FIGS. 2 and 4, the mounting tube 10 is hollow, is elastically deformable and is mounted around the inner end of the inner barrel 44 between the half-shells 41, 42. The mounting tube 10 has an external surface, an internal surface, a top segment, a positioning protrusion 11 and a pressing block 12. The positioning protrusion 11 is formed on and protrudes from the external surface of the mounting tube 10 and is mounted securely in the positioning recess 45 of the first half-shell 41 to hold the mounting tube 10 between the half-shells 41, 42. The pressing block 12 is formed on and protrudes downwardly from the internal surface of the mounting tube 10 at the top segment of the mounting tube 10.

The driven element 20 is mounted in the mounting segment of the first half-shell 41, is pressed against the mounting tube 10 and has an inner side, an outer side, an upper end, a lower end, an extending wing 21 and a holding segment 23. The inner side of the driven element 20 faces the external surface of the mounting tube 10. The outer side of the driven element 20 faces the internal surface of the first half-shell 41.

The extending wing 21 is elastic, is formed on and protrudes curvedly from the upper end of the driven element 20 and extends to the top segment of the mounting tube 10. The extending wing 21 has a free end, a bottom side, a top side and a protruding post 22. The free end of the extending wing 21 extends to the top segment of the mounting tube 10. The protruding post 22 is formed on and protrudes downwardly from the bottom side of the extending wing 21 at the free end above the pressing block 12 of the mounting tube 10.

The holding segment 23 is formed in the outer side of the driven element 20 at the lower end of the driven element 20 and is securely mounted in the holding recess 46 of the first half-shell 41.

The driving element 30 is movably mounted in the second half-shell 42, is pressed against the extending wing 21 of the driven element 20 and has a main body 31, a turning tab 34 and a guiding groove 35. The main body 31 is movably mounted in the second half-shell 42 and has an inner side, an outer side, a bottom end 32 and a top end 33. The inner side of the main body 31 faces the external surface of the mounting tube 10. The outer side of the main body 31 faces the internal surface of the second half-shell 42. The top end 33 of the main body 31 extends above the top side of the extending wing 21 to enable the inner side of the main body 31 at the top end 33 to press against the top side of the extending wing 21.

The turning tab 34 is formed on and protrudes from the outer side of the main body 31 near the bottom end 32 of the main body 31, is movably connected to the second half-shell 42 and extends out of the external surface of the second half-shell 42 via the adjusting slot 47. With reference to FIGS. 2 and 5, the turning tab 34 has an engaging protrusion 341. The engaging protrusion 341 is formed on and protrudes from the outer side of the main body 31 adjacent to the turning tab 34 and selectively engages one of the engaging teeth 471 of the adjusting slot 47 to adjust the position of the main body 31 relative to the driven element 20, the mounting tube 10 and the second half-shell 42.

With reference to FIGS. 2 and 5, the guiding groove 35 is formed in the inner side of the main body 31 from the top end 33 to the bottom end 32 of the main body 31 for mounting the main body 31 around the extending wing 21 of the driven element 20 and to enable the main body 31 to press against the internal surface of the first shell 41 and the extending wing 21, and the guiding groove 35 has a depth gradually deepened from the bottom end 32 to the top end 33 of the main body 31. In other words, the depth of the guiding groove 35 at the top end 33 of the main body 31 is deeper than the depth of the guiding groove 35 at the bottom end 32 of the main body 31.

In use, with reference to FIGS. 2 and 5, a pellet 50 is mounted between the mounting tube 10 and the inner end of the inner barrel 44, and the pressing pressure of the pressing block 12 that is pressed against the pellet 50 is provided by the main body 31 pressing against the extending wing 21 to enable the protruding post 22 to press against the top segment of the mounting tube 10.

With reference to FIGS. 3 and 5, when the turning tab 34 is held on the lower end of the adjusting slot 47 by the engaging protrusion 341 engaging one of the engaging teeth 471 at the lower end of the adjusting slot 47, the main body 31 is pressed against the extending wing 21 near the top end 33 of the main body 31. With reference to FIGS. 6 and 7, when the turning tab 34 is pushed upwardly relative to the second half-shell 42 along the adjusting slot 47 and is held in the adjusting slot 47 near the upper end of the adjusting slot 47 by the engaging protrusion 341 engaging one of the engaging teeth 471 near the upper end of the adjusting slot 47, the top end 33 of the main body 31 is moved on and across the protruding post 22 of the extending wing 21 and the main body 31 is pressed against the extending wing 21 between the top end 33 and the bottom end 32 of the main body 31 to enable the top segment of the mounting tube 10 to deform to press against the pellet 50.

According to the above-mentioned operation of the turning tab 34, because the depth of the guiding groove 35 at the top end 33 of the main body 31 is deeper than the depth of the guiding groove 35 at the bottom end 32 of the main body 31, the pressing pressure of the pressing block 12 when the top end 33 of the main body 31 is moved on and across the protruding post 22 of the extending wing 21 is larger than the pressing pressure of pressing block 12 when the top end 33 of the main body 31 is moved above the protruding post 22 of the extending wing 21.

With the gradual changes in depth of the guiding groove 35, the main body 31 of the driving element 30 can provide different pressing pressures to the pellet 50 via the protruding post 22 of the extending wing 21 and the pressing block 12 of the mounting tube 10. Furthermore, the pellet 50 can receive different pressing pressures from the pressing block 12 of the mounting tube 10, when the toy gun is fired, the rotating force and the ejection stroke of the pellet 50 vary with the changes of the pressing pressure. In other words, when the pellet 50 receives a larger pressing pressure from the pressing block 12, the toy gun can provide a larger rotating force and a longer ejection stroke to the pellet 50.

Consequently, because the depth of the guiding groove 35 is different from the top end 33 to the bottom end 32 of the main body 31, a user can adjust the rotating force and the ejection stroke of the pellet 50 between the mounting tube 10 and the inner barrel 44 by pushing the turning tab 34 relative to the second half-shell 42 along the adjusting slot 47 to provide different pressing pressures to the pellet 50 via the main body 31, the protruding post 22 of the extending wing 21, and the pressing block 12 of the mounting tube 10. The pellet 50 can be ejected by the toy gun with different rotating forces and different ejection strokes according to the user's need.

Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
