ARROW MAGAZINE STRUCTURE CAPABLE OF DETECTING NO-ARROW AND PREVENTING STRING-PULLING

Abstract

An arrow magazine structure capable of detecting no-arrow and preventing string-pulling is configured to accommodate a body. The body includes a holder, a bowstring spanning the holder. The arrow magazine structure contains an arrow magazine, a flexible abutting unit, and a retainer. The arrow magazine includes a fixing channel which has multiple arrows. The flexible abutting unit includes a presser and a resilient element. The retainer is accommodated on the holder and includes a first end and a second end. The retainer includes a biasing portion and a shoulder. A rotatable connection portion of the retainer and the holder is located between the shoulder and the biasing portion, the biasing portion is configured to press the contact portion downward so as to lift the shoulder upward, and the shoulder stops the bowstring being pulled, thus reminding a running out of the arrow of the arrow magazine.

DETAILED DESCRIPTION

[0024] With reference to FIGS. 1-7, an arrow magazine structure capable of detecting no-arrow and preventing string-pulling according to a preferred embodiment of the present invention is configured to accommodate a body 1 (in this embodiment, the body 1 is a crossbow), the body 1 includes a holder 1A, a bowstring 1B spanning the holder 1A, and a shooting direction 1C, a sliding rail 1D defined on the holder 1A, and a receiving groove 1E formed on a bottom of the sliding rail 1D. The arrow magazine structure 2 comprises an arrow magazine 10, a flexible abutting unit 20, a retainer 30, and a ruler bar 40.

[0025] The arrow magazine 10 is an elongated box and includes a front end 10A and a rear end 10B, the arrow magazine 10 includes a fixing channel 11 vertically passing through the arrow magazine 10 and communicating with the holder 1A of the body 1, wherein the fixing channel 11 has multiple arrows 12 stacked together, and a respective one arrow 12 has an arrowhead 121 facing the shooting direction 1C.

[0026] The flexible abutting unit 20 includes a presser 21 and a resilient element 22, wherein the presser 21 is elongated and has a connection orifice 211 defined on an end of the presser 21 and configured to receive a shaft 212 so that the presser 21 is rotatably connected on the body 10, and the presser 21 also has a contact portion 213 formed in an arc shape and on the other end thereof, the resilient element 22 is fixed on a rotatable connection portion of the presser 21 and the arrow magazine 10, the resilient element 22 elastically forces the contact portion 213 of the presser 21 to abut against a topmost arrow 12 of the fixing channel 11. In this embodiment, the presser 21 is rotatably connected on an outer wall of the fixing channel 11 of the arrow magazine 10, and the resilient element 22 is a torsion spring.

[0027] The retainer 30 is accommodated in the receiving groove 1E of the sliding rail 1D, and the retainer 30 includes a first end 30A and a second end 30B opposite to the first end 30A, wherein the retainer 30 is rotatably connected on the holder 1A by using the first end 30A and the second end 30B (In this embodiment, the retainer 30 includes a coupling orifice 31 defined on an eccentric portion thereof proximate to the first end 30A and configured to receive a post 32), wherein the retainer 30 includes a biasing portion 33 formed on a top thereof adjacent to the first end 30A, and a shoulder 34 being tilted and formed on the second end 30B of the retainer 30, wherein the rotatable connection portion of the retainer 30 and the holder 1A is located between the shoulder 34 and the biasing portion 33. In a normal state, the retainer 30 is forced by the respective one arrow 12 of the fixing channel 11 and contacts with an edge of the receiving groove 1E by mating with the shoulder 34 of the retainer 30 so that the top of the retainer 30 is received in the receiving groove 1E horizontally, the biasing portion 33 is configured to press the contact portion 213 of the presser 21 downward so as to lift the shoulder 34 of the retainer 30 upward, and the shoulder 34 stops the bowstring 1B being pulled, thus detecting and reminding a running out of the arrow 12 of the arrow magazine 10.

[0028] The ruler bar 40 is disposed on a top of the arrow magazine 10, and the ruler bar 40 includes a rotatable connection portion 41 and a connection seat 42 which are formed on an end of the ruler bar 40, an engagement portion 43 formed on the other end of the ruler bar 40, wherein the rotatable connection portion 41 is rotatably connected on the rear end 10B of the arrow magazine 10, the engagement portion 43 is movably engaged with the front end 10A of the arrow magazine 10. In this embodiment, the connection seat 42 is configured to fit with the presser 21, the connection orifice 211 is rotatably connected with the connection seat 42 of the ruler bar 49 by using the shaft 212, and the resilient element 22 is fitted on the shaft 212 to abut against between the presser 21 and the connection seat 42.

[0029] In operation, as shown in FIG. 8, the resilient element 22 pushes the contact portion 213 of the presser 21 downward to abut against the multiple arrows 12 of the fixing channel 11 so that a bottommost arrow 12 drops to the sliding rail 1D of the holder 1A of the body 1, and the bowstring 1B is pulled tightly to shoot the bottommost arrow 12 from the sliding rail 1D, thus shooting the multiple arrows 12 in turns to rapidly draw and fix the multiple arrows 12 successively.

[0030] After completely shooting the multiple arrows 12 of the arrow magazine 10 from the fixing channel 11, as shown in FIGS. 9 and 10, the biasing portion 33 presses the contact portion 213 of the presser 21 downward so as to lift the shoulder 34 of the retainer 30 upward, wherein when the bowstring 1B is pulled to move away from the shooting direction 1C, the shoulder 34 of the retainer 30 stops the bowstring 1B being pulled, thus detecting and reminding the running out of the arrow 12 of the fixing channel 11 of the arrow magazine 10. Accordingly, it is evitable that no-arrow in the arrow magazine 10 causes dry fire to damage the body 1 and related devices and components.

[0031] When the fixing channel 11 of the arrow magazine 10 is empty, as shown in FIG. 11, the engagement portion 43 of the ruler bar 40 is disengaged from the front end 10A of the arrow magazine 10, the rotatable connection portion 41 of the ruler bar 40 is rotated upward and backward to actuate the presser 21 to rotate upward so as to remove the presser 21 from the fixing channel 11, hence more multiple arrows 12 are received in the fixing channel 11 and are stacked together, and the arrowhead 121 of the respective one arrow 12 faces the shooting direction 1C, then the ruler bar 30 is rotated downward to engage the biasing portion 33 with the front end 10A of the arrow magazine 10, and the contact portion 213 of the presser 21 downward abuts against the topmost arrow 12 of the fixing channel 11, thus accommodating and shooting the multiple arrows successively.

[0032] Accordingly, the arrow magazine structure of the present invention has advantages as follows: [0033] 1) The contact portion 213 of the presser 21 is configured to abut against the multiple arrows and is not broken by a pulling force of the bowstring 1B, thus enhancing durability and service life. [0034] 2) When the fixing channel 11 of the arrow magazine 10 is empty, the ruler bar 30 stops the bowstring 1B from being pulled, so the flexible abutting unit 20 is movably mounted based on using requirements, thus providing diversified choices in a product structure design.

[0035] While the first embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
