Abstract
A crossbow includes a barrel with a flight groove 11, and a bow. A magazine 2 is mounted to the barrel and located above the flight groove 11. A passage 21 is defined through the magazine 2 for accommodating multiple arrows therein (22, see e.g. figure 9A). A slot 23 is formed between the magazine 2 and the flight groove 11. A string 122 of the bow movably extends through the slot 23. An arm 3 is pivotally located in the passage 21 and includes a hook end 31 which presses on a top-most arrow of the arrows in the magazine 2 when there are arrows present in the magazine 2. When no arrow is in the magazine 2, the hook end 31 is inserted into the slot 23 and a user cannot successfully cock the string 122 because the string 122 is stopped by the hook end 31, so that the user is made aware that there is no arrow in the magazine 2.
Description
A PROTECTION DEVICE FOR A CROSSBOW BACKGROUND OF THE INVENTION
1. Fields of the invention
The present invention relates to a protection device for a crossbow, 5 and, more particularly, to a protection that allows the users to shoot continuously, and prevents them from proceeding with a shooting action when there are no arrows in the magazine.
2. Descriptions of Related Art
The conventional way to use a crossbow is to load an arrow into the flight groove on the barrel of the crossbow, and then cock 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 pick up another arrow to load the arrow onto the crossbow, in the steps mentioned previously. However, these repeated steps break the tempo of the shooter and the crossbow has to be removed from the shooting position for reloading another arrow. In order to remove the shortcomings mentioned above, a magazine is chosen which has multiple arrows loaded therein so that the user is able to shoot the arrows continuously without interruption.
Taiwanese Patent Number 1678510 discloses a pull arm which is combined with the string and includes a box which has one end thereof connected to the arm, and the other end of the box has a connection portion.
The box includes a slot which extends through the box and communicates with the connection portion. The string of the crossbow operationally extends through the slot. A magazine is installed to the connection portion of the box and may be loaded with multiple arrows via an entrance of the 5 magazine. A pressor is pivotally connected to the magazine and biased by a spring. The pressor is inserted into the entrance and presses the top-most arrow so as*to feed the arrows one by one into the flight groove to be shot. However, the user may not notice the number of arrows left in the magazine due to focusing on the shooting action. When the user pulls the 10 trigger when no arrow is fed from the magazine, the recovery force of the string is absorbed by the body of the crossbow and other pans, and the string may be damaged or even broken. Even worse, the parts may be splashed out and hit the user to become safety concerns.
The present invention intends to provide a protection device of a 15 crossbow designed to eliminate the shortcomings mentioned above.
SUMMARY OF THE INVENTION
The present invention relates to a crossbow and includes a barrel with a flight groove, and a bow is located at one end of the flight groove. A magazine is mounted to the barrel and located above the flight groove. A passage is defined through the ma2azine. Multiple arrows are piled and located within the passage. A slot is formed between the magazine and the flight groove. The string of the bow movably extends through the slot. An arm is pivotally located in the passage and includes a hook end which normally presses on the top-most arrow of the arrows in the magazine. When there is no arrow in the magazine, the hook end is inserted into the slot and, when the string is pulled in a direction opposite to the shooting direction of the crossbow, the hook end hooks the string of the bow. The user then cannot successfully cock the string because the string is stopped by the hook end, so that the user is made aware that there is no arrow in the magazine.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figs. 1 to 10, the crossbow of the present invention comprises a barrel 1 having a flight groove 11 formed on the top thereof, and a bow 12 and a stock are respectively located at two ends of the barre I. The bow 12 is located above the flight groove 11. A magazine 2 is mounted to the barrel 1 and located above the flight groove 11. A passage 21 is defined through the top and the bottom of the magazine 2 so that multiple arrows 22 can be piled and located within the passage 21. A slot 23 is formed between the magazine 2 and the flight groove 11. The bow 12 includes two limbs 121 and the string 122 which is connected between the two limbs 121. The barrel 1 of the crossbow is located between the two limbs 121. The string 122 movably extends through the slot 23.
An arm 3 is pivotably located in the passage 21 and includes a hook end 31 which normally presses on the top-most arrow of the arrows 22 in the magazine 2.
When there is no arrow in the magazine 2, the hook end 31 is inserted into the slot 23 such that, when the user does not know there is no arrow in the magazine 2 and the string 122 is pulled in a direction opposite to the shooting direction of the crossbow (cocking the string), the hook end 31 hooks the string 122 of the bow 12 to restrict the string 122 from being further pulled. In this way, the user is made aware that there is no arrow in the magazine 2, and the string 122 cannot be cocked. The user simply releases the string 122 back to its initial position. Because the string 122 is just pulled a limited distance, the problem described in the conventional crossbows can be avoided.
As shown in Figs. 3 to 6, the arm 3 includes a press section 33 and a body portion 32. The body portion 32 is formed between the hook end 31 and the press section 33. The body 32 includes multiple bores 321 defined therethrough. A hole 24 is formed in each of two insides of the passage 21, so that a pin 34 extends through the two holes 24 and one of the bores 321 to pivotably position the arm 3 in the passage 21. The press section 33 partially protrudes beyond the passage 21 and includes an operation section 332 which can be pressed by the user to pivot the arm 3 from the slot 23 in a direction away from the passage 23. By inserting the pin 34 through different one of the bores 321, the length of the arm 3 in the passage 21 can be adjusted, so that the arrows 22 of different lengths can be loaded in the magazine 2 and properly pressed by the arm 3.
As shown in Figs. 6 to 9A, a block 25 is located in one end of the passage 21 and includes a first inclined face 252 and a second inclined face 253 which is formed with the first inclined face 252. A first dent 251 is defined in the first inclined face 252 faces the press section 33. The press section 33 includes a second dent 331 which is located corresponding to the first dent 251. Two ends of a spring 4 are respectively positioned in the first and second dents 251, 331.1n other words, the arm 3 is pivotable about the pin 34 and the spring 4 pushes the press section upward so that the hook end 31 of the arm 3 is pivoted toward the slot 23. The arm 3 is always biased by the spring 4 to press the topmost arrow 22 in the magazine even when the crossbow is tilted or unbalanced, so that the arrows 22 do not drop out from the magazine 2. As shown in Fig. 10, the arm 3 is naturally inserted into the slot 23 due to gravity and the force of the spring 4. When no arrow is in the passage 21 and the arm 3 is located in the slot 23 as mentioned before, the arm 3 is tilted and the body portion 32 of the arm 3 is not in contact with the second inclined face 253.
As shown in Fig, 11, the spring 4 is compressed when the operation section 332 of the press section 33 is pressed, and the arm 3 is pivoted from the slot 23 in a direction away from the passage 23. The arm 3 pivots downward into the magazine 2 when releasing the press section 33 to release the spring 4.
As shown in Fig. 10, the hook end 31 of the arm 3 includes a hooking portion 311. When there is no arrow in the magazine 2, the hook end 31 is located in the slot 23. When the string 122 is pulled, the string 122 is hooked by the hooking portion 311 of the hook end 31 located in the slot 23. Therefore, the string 122 cannot be further pulled, and the user knows that no arrow 1 is left in the magazine 2.
As shown in Figs. 3 to 5. and 10 to 13, the passage 21 includes an entrance 26 and an exit 27. By pressing the operation section 332 of the press section 33 to pivot the arm 3 upward, arrows 22 can be loaded into the passage 21 via the entrance 26. After loading, the arm 3 presses on the topmost arrow 22, and the lowest one of the arrows 22 drops into the slot 23 via the exit 27.
Further referring to Figs. 1 and 2, the crossbow includes a trigger unit 13 which includes a trigger 131. As shown in Figs. 6 to 9A, when the string 122 is cocked, the lowermost arrow 22 is located in the slot 23, the trigger 131 is pulled by the user to release the string 122 to shoot the arrow 22 in the slot 23. Then the lowermost arrow 22 drops into the slot 23 by the pressing force of the arm 3, the user does not need to re-load the arrow 22 to shorten the shooting time between shoots.
The present invention provides a protection device that arranges the arm 3 to be located in the slot 23 so that the user is made aware that there is no arrow 2 in the magazine 2 because the string 122 cannot be successfully cocked.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in 20 the art that further embodiments may be made without departing from the scope of the present invention.
