Description

BACKGROUND OF THE INVENTION

1. Fields of the Invention

The conventional way to use the crossbow is to load an arrow into the flight groove on the barrel of the crossbow, and then cocking the arrow to pull the string. When pulling the trigger, the arrow is shot by the recovery force of the string. Then the user has to lower the crossbow and picks another arrow to load the arrow onto the crossbow as the steps mentioned previously. However, these repeated steps break the temple of the shooters and the crossbow has to be removed from the shooting position for reloading another arrow.

A portion of the case 104A protrudes from the barrel 102.

The magazine 1 includes a chamber 12 which does not communicate with the storage space 11. The portion of the case 104A protruding from the barrel 102 is accommodated in the chamber 12 of the magazine 1 so as to prevent foreign objects from entering to affect the operation of the press member 104B and the passive member 104C.

The press member 104B 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 104B is located between the block 109 and the inside of the room 106. The press member 104B includes a first notch 110 and a second notch 110A respectively facing the block 109. A ball 111 is biased by a first spring 112 which is located in the block 109. The ball 111 is selectively engaged with the first notch 110A or the second notch 110B.

As shown in FIGS. 7A and 7B, the rear section 1R of the magazine 1 includes a first hole 1H defined transversely therethrough and the trigger assembly 104 includes a second hole 1040 that is located corresponding to and communicates with the first hole 1H. A connection pin “P” removably extends through the first hole 1H and the second hole 4010. The connection pin “P” includes a flange “P1” and a shank “P2” that extends from the flange “P1”. The flange “P1” extends radially and outward from one end of the connection pin “P”. The flange “P1” is located within the first hole 1H and the shank “P2” extends beyond the second hole 1040. The shank “P2” includes a keyway “P21” defined in the distal end thereof which can be accessed via the first hole 1H.

Referring to FIGS. 6A to 6C again, when the magazine 1 is to be mounted to the top of the barrel, the magazine 1 is slid along the top of the barrel to engage the first engaging members 15 with the second engaging members 100. The magazine 1 is further secured to the barrel by the connecting pin “P”, simply pushes the flange P1 toward the keyway P21 to extend the connection pin “P” through the first and second holes 1H, 1040. Therefore, the magazine 1 is secured to the barrel in both horizontal direction and vertical direction relative to the barrel. When the user needs to remove the magazine 1 from the crossbow 10, the user simply pushes the keyway P21 toward the flange P1 to remove the connection pin “P” from the first and second holes 1H, 1040.

The trigger 104D has the first end thereof pivotably connected in the room 106, and the second end of the trigger 14 extends beyond the second opening 108 of the case 104A. The passive member 104C is pivotably located in the room 106, and located between the press member 109 and trigger 104D. The passive member 104C is located on the trigger 104D and contacts the press member 104B. The passive member 104C contacts the distal end of the second portion of the press member 104B. A second spring 104G is biased between the passive member 104C and the block 109. The stop 104 is pivotably connected to the case 104A by a first pin 113 and is located in the room 106. The first end of the stop 104E normally contacts the passive member 104C, and the second end of the stop 104E extends beyond the first opening 112. It is noted that the stop 104 includes a U-shaped opening which accommodates the torsion spring 104F and is used to avoid from touching the lowest arrow 20 to be lowered. A second pin 114 is located in the room 1106 and beside the first pin 113. The torsion spring 104F includes two ends which are respectively mounted to the first and second pins 113, 114. The torsion spring 104F provides a force to return the stop 104E to its initial position after the stop 104E is pivoted. The press member 104B includes two rods 115 respectively extending from two sides thereof. The two rods 115 extend beyond the case 104A and are movably located in the slot 105. When the two rods 115 are shifted to move the press member 104B, the ball 111 is moved to be engaged with one of the first and second notches 110, 110A.

When in use, the retainer 2 is pivoted upward from the storage space 11, and loading arrows 20 into the storage space 11. The retainer 2 is released to press the arrows 20. The string 103B is located close to the front end 102A and stops the arrow 20 to be lowered toward the barrel 102. The string 103B is then pulled in the slot 105 and toward the rear end 102B of the barrel 102. The string 103B then touches and pivots the stop 104E. After the string 103B moves over the stop 104E, the stop 104E returns to its initial position by the recovery force of the torsion spring 104F. The string 103B is restricted from shooting by the stop 104E. The lowest arrow 20 in the storage space 11 enters into the flight groove 101 of the barrel 102 because of the string 103B does not restricts the arrow 20 to be lowered. It is noted that the string 103B is restricted from shooting by the stop 104E because the ball 111 is engaged with the first notch 110, and the press member 104B and the passive member 104C contact and restrict each other. Therefore, the passive member 104C cannot pivot, and the passive member 104C restricts the stop 104E to pivot, so as to restrict the string 103B from shooting.

After the arrow 20 is located in the flight groove 101 of the barrel 102, the user push the rods 115 to move the press member 104B toward the front end 102A of the barrel 102 to remove the ball 111 from the first notch 110, and the ball 111 is shifted to be engaged with the second notch 110A. Therefore, the press member 104B is released, and the passive member 104C is pivotable. The user then aim the target and pulls the trigger 104D which pivots the passive member 104C. The pivotal movement of the passive member 104C releases the stop 104E so that the string 103B pivots the stop 104E. The string 103B then shoots the arrow 20. By repeating the steps mentioned above, the lowest arrow 20 enters into the flight groove 101 so that the user is able to shoot continuously.

The case 104A includes a first part 116 and a second part 117 which is mounted to the first part 116 to from the room 106. The first part 116 and the second part 117 each have an elongate hole 118, and the two rods 115 extend through the elongate holes 118 and are moveable in the slot 105 so that the users can conveniently operate the rods 115 as shown in FIG. 7. The movement of the rods 115 controls the movement of the press member 104B and shifts the ball 111 to be engaged with one of the first and second notches 110, 110A.

The present invention also provides the second embodiment and the third embodiment of the retainers 4, 6, and the main difference of the second embodiment and the third embodiment of the retainers 4, 6 from the first embodiment of the retainer 2 is the way to load the arrows 20. As shown in FIGS. 15 to 20 which show the second embodiment of the retainer 4. The second embodiment of the retainer 4 is located in the storage space 11 and resiliently and normally presses the arrows 20. The retainer 4 includes a plate 41 and a spring 42. The plate 41 has the first end thereof pivotably connected to the inside of the storage space 11, and a pin 5 removably extends through the magazine 1 and extends through the second end of the plate 41. The spring 42 is connected to the underside of the plate 41 and presses the arrows 20 in the storage space 11. Specifically, the spring 42 is a wave-shaped spring or a Z-shaped spring, and has flexibility. Therefore, the plate 41 is able to be pivoted upward as shown in FIG. 19 and extends the spring 42. The plate 41 is pulled beyond the storage space 11, and the arrows 20 are loaded into the storage space 11. The plate 41 is then released to cover the storage space 11. The plate 41 is positioned by using the pin 5. The spring 42 presses the loaded arrows 20.

As shown in FIGS. 21 to 26 which shows the third embodiment of the retainer 6. In this embodiment, a chamber 13 formed along the two insides of the second section 11B of the storage space 11. The retainer 6 is located in the chamber 13 of the storage space 11, and resiliently and normally presses the arrows 20 in the storage space 11. The retainer 6 includes a top board 61 and a protrusion 62 extending from the underside of the top board 61. That is to say, the retainer 6 is a T-shaped retainer. Two recessed areas 63 are formed between the underside of the top board 61 and the protrusion 62. Multiple springs 7 are respectively located in the two recessed areas 63. Each spring 7 have the first end thereof connected to underside of the retainer 6, and the second end of each spring 7 is connected to the inner bottom of the storage space 11. When loading the arrows 20, the retainer 6 is pulled upward to extend the multiple springs 7, and the retainer 6 is lifted beyond the storage space 11, the arrows 20 are able to be loaded into the storage space 11. When the retainer 6 is released, the retainer 6 returns into the storage space 11 and resiliently presses the arrows 20 in the storage space 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.
