Referring to FIGS. 1 to 9A, the arrow feeding device for a crossbow of the present invention comprises a magazine 3 mounted to the top of the crossbow 1. A storage space 31 is defined through the magazine 3 from the top of the magazine 3 to the open bottom of the magazine 3. Multiple arrows 2 are loaded in the storage space 31. A retainer 4 includes a first end pivotably connected to the magazine 3 and located in the storage space 31. A second end of the retainer 4 normally presses the arrows 2 in the storage space 31 to ensure that the lowest arrow 2 enters into the barrel 11 of the crossbow 1 in sequence. Specifically, an end piece 311 is located at one end of the storage space 31. The end piece 311 includes a first recess 312. The first end of the retainer 4 includes a second recess 41. Two ends of a compressing spring 5 are respectively engaged with the first and second recesses 312, 41. The compressing spring 5 biases the retainer 4 so that the second end of the retainer 4 normally presses the top arrow of the arrows 2 in the storage space 3.
As shown in FIGS. 2 to 4, the storage space 31 of the magazine 3 includes a first section 313, a second section 314 and a third section 315. The second section 314 is located between the first section 313 and the third section 315. The first, second and third sections 313, 314, 315 communicate with each other. An opening of the second section 314 is formed on the top of the magazine 3 and is narrower than that of each of the first and third section 313, 315. Each arrow 2 includes a head 21, a tail 22 and a shank 23 which is formed between the head 21 and the tail 22. The head 21 of the arrow 2 is located in the first section 313. The tail 22 of the arrow 2 is located in the third section 315. The shank 23 of the arrow 2 is located in the second section 314. The shank 23 of the arrow 2 contacts two sidewalls of the second section 314, such that all of the arrows 2 in the space 31 is positioned as expected and do not tilt. By this arrangement, the arrows 2 can be fed stably and correctly as shown in FIGS. 3 and 3A.
There are two ways to pull the string 122, and the present invention can be used with any of the two known ways to pull the string 122. The crossbow 1 includes the barrel 11, a bow assembly 12 and a trigger assembly 13. The barrel 11 includes a front end 111 and a rear end 112. A groove 113 is defined in the top of the front end 111 of the barrel 11. The magazine 3 is mounted to the barrel 11 and located above the groove 113. A slot 114 is formed between the magazine 3 and the barrel 11. The bow assembly 12 includes a bow 121 and a string 122 which is connected between two ends of the bow 121. The bow 121 is fixed to the barrel 11, and the string 122 extends through the slot 114, so that the string 122 can be pulled within the slot 114. The trigger assembly 13 is connected to the barrel 11 and located close to the rear end 112 of the barrel 11. The trigger assembly 13 includes a case 131, a press member 132, a passive member 133, a trigger 14, a stop 15, a torsion spring 16 and a first spring 17. The case 131 includes a room 134. A first opening 135 and a second opening 136 are formed to the case 131 and communicate with the room 134. A block 137 extends from inside of the room 134. A portion of the case 131 protrudes from the barrel 11. The magazine 3 includes a chamber 32 which does not communicate with the storage space 31. The portion of the case 131 protruding from the barrel 11 is accommodated in the chamber 32 of the magazine 3 so as to prevent foreign objects from entering to affect the operation of the press member 132 and the passive member 133.
The press member 132 is an inverted L-shaped member which includes a first portion and a second portion which extends from one end of the first portion. The first portion of the press member 132 is located between the block 137 and the inside of the room 134. The press member 132 includes a first notch 132A and a second notch 132B respectively facing the block 137. The block 137 includes a ball 18 which is biased by a first spring 17 which is located in the block 137. The ball 18 is selectively engaged with the first notch 132A or the second notch 132B.
The trigger 14 has a first end pivotably connected in the room 134, and a second end of the trigger 14 extends beyond the second opening 136 of the case 131. The passive member 133 is pivotably located in the room 134, and located between the press member 132 and trigger 14. The passive member 133 is located on the trigger 14 and contacts the press member 132. The passive member 133 contacts the distal end of the second portion of the press member 132. A second spring 181 is biased between the passive member 133 and the block 137. The stop 15 is pivotably connected to the case 131 by a first pin 19 and is located in the room 134. The first end of the stop 15 normally contacts the passive member 133, and the second end of the stop 15 extends beyond the first opening 135. It is noted that the stop 15 includes a U-shaped opening which is used to avoid from touching the lowest arrow 2 to be lowered. A second pin 191 is located in the room 134 and beside the first pin 19. The torsion spring 16 includes two ends which are respectively mounted to the first and second pins 19, 191. The torsion spring 15 provides a force to return the stop 15 to its initial position after the stop 15 is pivoted. The press member 132 includes two rods 132C respectively extending from two sides thereof. The two rods 132C extend beyond the case 131 and are movably located in the slot 114. When the two rods 132C are shifted to move the press member 132, the ball 18 is moved to be engaged with one of the first and second notches 132A, 132B.
The case 131 includes a first part 131A and a second part 131B which is mounted to the first part 131 to from the room 134. The first part 131A and the second part 131B each have an elongate hole 131C, and the two rods 132C extend through the elongate holes 131C and are moveable in the slot 114. The movement of the rods 132C controls the movement of the press member 132 and shifts the ball 18 to be engaged with one of the first and second notches 132A, 132B.
When in use, the retainer 4 is pivoted upward from the storage space 31, and loading arrows 2 into the storage space 31. The retainer 4 is released to press the arrows 2. The string 122 is located close to the front end 111 and stops the arrow 2 to be lowered toward the barrel 11. The string 122 is then pulled in the slot 114 and toward the rear end 112 of the barrel 11. The string 122 then touches and pivots the stop 15. After the string 122 moves over the stop 15, the stop 15 returns to its initial position by the recovery force of the torsion spring 16. The string 122 is restricted from shooting by the stop 15. The lowest arrow 2 in the storage space 31 enters into the groove 113 of the barrel 11 because of the string 122 does not restricts the arrow 2 to be lowered. It is noted that the string 122 is restricted from shooting by the stop 15 because the ball 18 is engaged with the first notch 132A, and the press member 132 and the passive member 133 contact and restrict each other. Therefore, the passive member 133 cannot pivot, and the passive 133 restricts the stop 15 to pivot, so as to restrict the string 122 from shooting.
After the arrow 2 is located in the groove 113 of the barrel 11, the user push the rods 132C to move the press member 132 toward the front end 111 of the barrel 11 to remove the ball 18 from the first notch 132A, and the ball 18 is shifted to be engaged with the second notch 132B. Therefore, the press member 132 is released, and the passive member 133 is pivotable. The user then aim the target and pulls the trigger 14 which pivots the passive member 133 as shown in FIG. 9. The pivotal movement of the passive member 133 releases the stop 15 so that the string 122 pivots the stop 15 as shown in FIG. 9. The string 122 then shoots the arrow 2. By repeating the steps mentioned above, the lowest arrow 2 enters into the groove 113 so that the user is able to shoot continuously.
As shown in FIG. 10, the magazine 3 may have an aiming member 6 connected to the top thereof, wherein the aiming member 6 is located close to the rear end 112 of the barrel 11.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
