Pneumatic arrow gun for stably shooting arrows, safety device of an arrow and arrow with the same

Abstract

A pneumatic arrow gun has a gun body, an arrow, a positioning sleeve, and a connecting wire. The arrow is for inserting into an air tube of the gun body. The positioning sleeve is temporarily mounted around the air tube, and the arrow is disposed through the positioning sleeve. The connecting wire connects the gun body to the positioning sleeve. Because the positioning sleeve is temporarily mounted around the air tube, the arrow slides forward relative to the positioning sleeve after triggering. When triggering the arrow, the connecting wire naturally dangles. When the arrow detaches from the air tube, the positioning sleeve located at a nock of the arrow due to the sliding of the arrow. Therefore, a rebound of the arrowhead is prevented. The safety and the shooting stability are ensured. Further, the arrow is easily retrieved by the connecting wire.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) With an embodiment and drawings thereof, the features of the present invention are described in detail as follows.

(9) With reference to FIG. 1, a pneumatic arrow gun for stably shooting arrows in accordance with the present invention comprises an air gun 10, an arrow 20, a positioning sleeve 30, and a connecting wire 40.

(10) The air gun 10 comprises a gun body 11 and an air tube 12, and may further comprise a reel 13. The air tube 12 is connected to the gun body 11, and the reel 13 is mounted on the gun body 11. In the present embodiment, the gun body 11 comprises an air bottle 111, a connecting pipe 112, a switch unit 113, and a trigger 114. The air bottle 111 is mounted on the gun body 11, has an air outlet 1111 disposed into the gun body 11, and stores a high-pressure gas therein. The connecting pipe 112 is disposed in the gun body 11 and connects between the air outlet 1111 of the air bottle 111 and the air tube 12. The switch unit 113 is mounted inside the gun body 11 and is connected to the connecting pipe 112. The trigger 114 is connected to the switch unit 113 and exposed from the gun body 11. A user pulls the trigger 114 to turn on the switch unit 113 so that the air bottle 111 selectively communicates with the air tube 12. Thus, the high-pressure gas stored in the air bottle 111 is used as a source of a thrust force for the air gun 10.

(11) The arrow 20 is disposed in the air tube 12 of the air gun 10. When the trigger 114 of the gun body 11 is pulled, the arrow 20 is pushed forward by the high-pressure gas to detach from the air tube 12. The arrow comprises a nock, a shaft 22, and an arrowhead 23 from back to front. As shown in FIG. 3, in one embodiment, the nock is consisted of a nock sleeve 21 to mount around a back end of the shaft 22. The nock sleeve 21 is disposed in the air tube 12 of the air gun 10. In the present embodiment, the nock sleeve 21 has an outer diameter D1 matching an inner diameter of the air tube 12, so that the nock sleeve 21 may be coaxially disposed in the air tube 12. The nock sleeve 21 comprises an annular groove 211 and an air-tight ring 212, the annular groove 211 is formed on an outside wall of the nock sleeve 21. In one embodiment, the annular groove 211 is formed near a rear end of the nock sleeve 21. The air-tight ring 212 may be made of a rubber, may be an O-ring, is mounted around the annular groove 211, and air-tightly contacts an inside wall of the air tube 12. When the user holds the air gun 10 and an air tube muzzle 121 of the air tube 12 faces downward, the air-tight ring 212 keeps the arrow 20 from slipping out of the air tube 12 by gravity. The air-tight ring 212 also keeps the high-pressure gas from leaking through a gap between the nock sleeve 21 and the air tube 12 when the arrow 20 is triggered so that the shooting power is retained. the shaft 22 may be a solid rod, but is not limited thereto. Most of the shaft 22 is disposed in the air tube 12 with the nock sleeve 21, and a small part of the shaft 22 at a front end thereof extends out of the air tube muzzle 121 of the air tube 12. In one embodiment, the arrowhead 23 is mounted around the front end of the shaft 22, is located outside the air tube 12, and comprises an arrow tip 231 and at least one barb 232. The arrow tip 231 is formed on a front end of the arrowhead 23. The at least one barb 232 is disposed on the arrowhead 23. An angle is defined between the arrowhead 23 and the at least one barb 232. After the arrowhead hits a target, the at least one barb 232 assists to fix the arrowhead 23 in the target.

(12) As shown in FIGS. 2 and 3, the positioning sleeve 30 is a safety device of an arrow in accordance with the present invention. The positioning sleeve 30 comprises a sleeve body 31 and a stop ring 32, and may further comprise a ring groove 33. The sleeve body 31 matches and is mounted around an outside wall of the air tube muzzle 121 of the air tube 12, that is, an inner diameter of the sleeve body 31 matches an outer diameter of the air tube muzzle 121. The stop ring 32 is integrally formed on an inside wall 311 of a front portion of the sleeve body 31 to abut against the air tube muzzle 121 of the air tube 12 and has an inner diameter corresponds to the outer diameter of the shaft 22. Thus, the shaft 22 of the arrow 20 stably and slidably disposed in the stop ring 32 and the air tube 12. In one embodiment, the positioning sleeve 30 may be coaxially mounted around the outside wall of the air tube muzzle 121 of the air tube 12 and may be coaxial with the nock sleeve 21 of the arrow 20. Therefore, after the arrow 20 is triggered, the arrow 20 does not shake radially and follows a stable trajectory to be triggered. A maximum width of the nock is larger than an inner diameter D2 of the stop ring 32. In one embodiment, the outer diameter D1 of the nock sleeve 21 is larger than the inner diameter D2 of the stop ring 32.

(13) The connecting wire 40 has a first end and a second end. The first end of the connecting wire 40 is fixed to the gun body 11 of the air gun 10, and the second end of the connecting wire 40 is fixed to the positioning sleeve 30. In the present embodiment, the first end of the connecting wire 40 is fixed to the reel 13, and the second end of the connecting wire 40 is fixed to the ring groove 33 of the positioning sleeve 30. A dangling wire between the first end and the second end is accommodated in the reel 13 so that the connecting wire 40 is naturally located at an underside of the air gun 10. Thus, the connecting wire 40 does not wrap around the air gun 10 or the arrow 20, a safety is ensured. After the arrow 20 detaches from the air gun 10, the connecting wire 40 assists the user to retrieve the arrow 20.

(14) A structure of the pneumatic arrow gun for stably shooting arrows in accordance with the present invention is described above, a shooting process is further introduced as follows.

(15) With reference to FIG. 4, when using the pneumatic arrow gun as described, the trigger 114 is pulled to turn on the switch unit 113. Subsequently, the connecting pipe 112 communicates the air outlet 1111 of the air bottle 111 and the air tube 12 of the air gun 10 to charge the high-pressure gas stored in the air bottle into the air tube 12, the nock sleeve 21 of the arrow 20 is pushed by the high-pressure gas, and the arrow 20 is triggered. As shown in FIG. 3, the air-tight ring 212 of the nock sleeve 21 air-tightly seals the gap between the nock sleeve 21 and the air tube 12. Thus, a pressure provided by the high-pressure gas is efficiently converted to a thrust force of the arrow 20 and the shooting power of the arrow 20 is effectively improved. Furthermore, the dangling wire of the connecting wire 40 is accommodated in the reel 13 and is naturally located at the underside of the air gun 10 because the sleeve body 31 of the positioning sleeve 30 is temporarily mounted around the air tube muzzle 121 of the air tube 12. Therefore, the connecting wire 40 does not affect the shooting trajectory of the arrow 20, and the safety when used is improved. Moreover, the stop ring 32 of the positioning sleeve 30 guides the shaft 22 of the arrow 20 to follow a stable trajectory because the shaft 22 of the arrow 20 is slidably disposed in the stop ring 32. Thus, the arrow does not shake in the air tube 12 when shooting, the shooting stability is also improved.

(16) After the arrow 20 is triggered by the air gun 10, the nock sleeve 21 of the arrow 20 slides forward and near the air tube muzzle 121 of the air tube 12, but has not detached from the air tube 12, and contacts the stop ring 32. With further reference to FIG. 5, after the arrow 20 detaches from the air tube 12, the positioning sleeve 30 and the second end of the connecting wire 40 fixed to the ring groove 33 detach from the air tube 12 with the nock sleeve 21. A tensile force of the connecting wire 40 does not affect the arrow 20 because the positioning sleeve 30 is located at the nock sleeve 21 of the arrow 20 after the arrow 20 detaches from the air tube 12, and a rebound of the arrowhead 23 is prevented. The arrowhead 23 of the arrow 20 is ensured to follow a correct trajectory to be shot and does not cause injury to the user. Furthermore, as shown in FIGS. 1 and 3, the first end of the connecting wire 40 is fixed to the reel 13 of the air gun 10. Thus, after the arrow 20 is shot or hits the target, the user retrieves the arrow 20 by the connecting wire 40 or further retrieves the target with the arrow 20 by the connecting wire 40.

(17) With the foregoing description, through fixing the connecting wire by the positioning sleeve, the connecting wire does not wrap around the air gun or the arrow. The trajectory of the arrow is not affected by the connecting wire. The sleeve body of the positioning sleeve matches and is mounted around the air tube muzzle of the air tube, and the shaft of the arrow is slidably disposed in the stop ring of the positioning sleeve. Thus, when the arrow slides forward and detaches from the air tube, the positioning sleeve is located at the nock sleeve of the arrow. The arrow is not affected by the tensile force of the connecting wire so that a rebound of the arrowhead is prevented and does not cause injury to the user, and the safety when using is ensured. Furthermore, by using the positioning sleeve and the stop ring to stabilize the shooting trajectory of the arrow, an additional guiding structure does not need to be formed in the air tube of the air gun, thus the air tube of the air gun is simplified. Moreover, the maximum width of the nock sleeve of the arrow, that is, the outer diameter of the nock sleeve is larger than the inner diameter of the stop ring of the positioning sleeve. Thus, when the nock sleeve of the arrow detaches from the air tube, the positioning sleeve also detaches from the air tube with the nock sleeve. At the same time, because the first and second ends of the connecting wire are respectively fixed to the reel of the air gun and the ring groove of the positioning sleeve, the user retrieves the arrow and the positioning sleeve through the connecting wire fixed to the reel.

(18) 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. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
