Description

[0001] The present invention relates to the technical field of archery and arrow shooting and in particular to an arrow body device with an arrow chain drive structure.

[0002] In contrast to the continuous firing of bullets in traditional target shooting, archery requires arrows to be picked up and nocked one after the other. This method places too much mental strain on archers. They are easily distracted, which in turn affects their accuracy and stability.

[0003] US patent 2009 / 0151710A1 discloses a feed chain for toy guns. The feed chain consists of individual links, each containing a hollow body for a projectile. A drive pinion engages with each link of the feed chain. A pumping motion of a handle mechanically advances the feed chain tooth by tooth to position each projectile. In use, a separate trigger is pressed to release compressed air from an internal reservoir, firing the projectiles from the toy gun.

[0004] US Patent 2016 / 0 187 085 A1 discloses various embodiments of a toy projectile launcher with a magazine for holding the projectiles to be fired. In one embodiment, the toy projectile launcher comprises a main housing, a passage that receives a magazine containing one or more projectiles and through which the magazine can be advanced, and a trigger mechanism movably attached to the housing. A feed element and the rear housing portion have recesses that can be engaged with the feed element to cause movement of the magazine relative to the housing. In an alternative embodiment, each of the recesses has an angled section that terminates in a flat section.The angled section is designed so that the feed element can slide along a surface of the angled section and engage with the flat section to move the magazine relative to the housing.

[0005] US patent 3,369,535A discloses a toy machine gun with belt feeding and a corresponding cartridge. Behind the rear end of the fixed barrel section, the rifle stock is fitted with a housing through which cartridge units can be sequentially advanced into firing position, aligned with the barrel. A flexible belt moves into the housing through an inlet on one side, is guided through the housing, and exits through an outlet on the opposite side. As the belt is inserted into the housing, the semi-cylindrical recesses engage sequentially with slots on the circumference of a wheel. The rotation of this wheel advances the cartridge carrier through the housing.

[0006] To enable users to fire continuously, archery and crossbow shooting sports do not use the aforementioned projectile chain, but rather the current "arrow device for crossbows" known from Taiwanese patent TW I738463. However, this arrow magazine has a few drawbacks. First, the number of arrows it can hold is limited. An excessively heavy magazine, in turn, increases the strain on the user. Second, disassembly and assembly are too time-consuming. This method undoubtedly impairs the user's concentration and stability while shooting.

[0007] The object of the present invention is to advantageously provide more arrows for shooting during continuous firing, while making operation simpler and more user-friendly. The present invention overcomes the shortcomings of the prior art.

[0008] To solve the aforementioned problem, the present invention provides an arrow-body device with an arrow-chain drive structure according to the independent claim. Preferred embodiments are the subject of the dependent claims. Fig. Figure 1 shows a schematic three-dimensional view according to the present invention, in which the pistol body and the upper pistol cover are combined; Fig. Figure 2 shows a schematic three-dimensional view according to the present invention, in which the upper pistol cover is pivoted and opened; Fig. Figure 2A shows a schematic three-dimensional exploded view of the arrow chain and the pistol body according to the present invention; Fig. Figure 3 shows a schematic exploded view of the chain drive assembly and the pistol body according to the present invention; Fig. Figure 4 shows a schematic three-dimensional exploded view of the chain drive arrangement according to the present invention; Fig. Figure 5 shows a schematic three-dimensional exploded view according to Fig. 4 from a different perspective; Fig. Figure 6 shows a schematic sectional view along section line VI-VI according to Fig. 1; Fig. Figure 7 shows a schematic sectional view along section line VII-VII according to Fig. 1; Fig. Figure 8 shows a schematic view of the movement actuation of the outer arrangement according to Fig. 1; Fig. Figure 9 shows a schematic view according to Fig. 6, in which the inner arrangement is driven to motion by the outer arrangement; Fig. 10, Fig. 11 and Fig. Figure 12 shows schematic views of the continuous movements according to Fig. 7, in which the arrow chain is pushed through the drive block and thereby moved after the chain drive assembly has been moved; Fig. Figure 13 shows a schematic view of the displacement of the first slide and the second slide of the chain drive arrangement according to the present invention; Fig. Figure 14 shows a schematic view from a different perspective according to Fig. 13.

The arrow body device according to the invention with arrow chain drive structure comprises the following: a pistol body 1 having a rear support 11 and a front drive section 12, wherein a pistol chamber 121 is provided within the front drive section 12 and the rear support 11 is connected to the front drive section 12; a chain hole 2 extending through the front drive section 12 from one side of the pistol body 1 to the other, wherein the arrow chain 10 is inserted from one side of the chain hole 2 and leads out on the other side, and several arrow bodies 20 are attached to the arrow chain 10; a drive assembly 3 comprising an inner arrangement 31 and an outer arrangement 32, wherein the inner arrangement 31 is located in the pistol chamber 121 and the outer arrangement 32 is located outside the pistol body 1 and is connected to the inner arrangement 31 and is displaceable forwards and backwards relative to the pistol body 1 and drives the inner arrangement 31 to movement; a chain drive assembly 4, which is located in the pistol chamber 121 and is near the rear support 11 and is driven to movement by the movement of the inner arrangement 31 and comprises a base 41, a first slide 42 and a second slide 43, wherein the base 41 has on its upper side a receiving space 411 designed as a recess, the first slide 42 and the second slide 43 are arranged to slide in the receiving space 411, a longitudinal direction A and a transverse direction B are defined in the receiving space 411,by means of pressure caused by the inner arrangement 31, the first slide 42 is displaceable along the longitudinal direction A and the second slide 43 along the transverse direction B, at least one inclined groove 421 designed as a recess is provided on the lower side of the first slide 42, an inclined guide block 431 is provided on the upper side of the second slide 43 and is inserted into the at least one inclined groove 421, the second slide 43 is moved to the left and right along the transverse direction B by the forward and backward movement of the first slide 42 guided along the longitudinal direction A, the drive hole 412 is continuously connected to the receiving space 411 and the chain hole 2 and runs through the base 41, and a drive block 5 is arranged at the end of the second slide 43 corresponding to the drive hole 412 and is located in the drive hole 412 and can be engaged with the arrow chain 10.

[0010] As in the Fig. 13 and Fig. As shown in Figure 14, the arrow chain 10 with the arrow bodies 20 is inserted into one end of the chain hole 2, with the chain drive assembly 4 being engaged with the drive block 5 beforehand. After the inner assembly 31 has been moved in the direction of the chain drive assembly 4 by a drive effected by the outer assembly 32, the first slide 42 is moved along the longitudinal direction A by a push effected by the inner assembly 31. The interaction between the first slide 42 and the second slide 43 is effected by the at least one inclined groove 421 and the inclined guide block 431. The first slide 42 is moved back and forth along the longitudinal direction A to drive the second slide 43 to move left and right along the transverse direction B. The pushing of the arrow chain 10 by the drive block 5 is controlled by moving the second slide 43.

[0011] Furthermore, one end of the base 41, near the chain hole 2, is laterally provided with a chain support recess 416. The drive hole 412 extends through the underside of the chain support recess 416. The drive block 5 is located in the drive hole 412 and is movable along the transverse direction B. The end of the drive block 5 that engages with the arrow chain 10 protrudes from the drive hole 412, so that after passing through the chain hole 2, the arrow chain 10 is placed on the chain support recess 416 and movably engaged with the drive block 5. Subsequently, the chain drive assembly 4 is driven by the drive group 3 to move; the first slide 42 is movable along the longitudinal direction A and the second slide 43 along the transverse direction B. The movement of the chain drive assembly 4 moves the drive block 5 to the left and right along the transverse direction B.At this point, the drive block 5 disengages from the position in which it was previously engaged with the arrow chain 10 and is returned to its original position and then engaged again with the arrow chain 10, as shown in the . Fig. 10, Fig. 11 to Fig. 12 is shown.

[0012] It will be directed to the Fig. 4, Fig. 13 and Fig. 14 Referenced. The base 41 comprises two shell covers 413, wherein the two shell covers 413 are joined together on the left and right to form a receiving space 411, rail projections 414 each protrude from the inner walls of both sides of the receiving space 411, corresponding to the rail projections 414 rail grooves 422 are recessed on two sides of the first slide 42 and the rail projections 414 are inserted into the corresponding rail grooves 422 and the two are slidably connected to each other, so that the first slide 42 can be moved easily without falling down in the receiving space 411.

[0013] As in the Fig. 4, Fig. 13 and Fig. As shown in Figure 14, at least one projecting plate 415 extends from the underside of the receiving space 411 towards the opening, the arrangement direction of the at least one projecting plate 415 corresponding to the transverse direction B, the underside of the second slide 43 is provided with an insertion recess 432 and the at least one projecting plate 415 is inserted into the insertion recess 432 to prevent the second slide 43 from sliding or falling uncontrollably in the receiving space 411.

[0014] The inclined groove 421 provided on the underside of the first slide 42 is inclined in a direction from bottom to top, from right to left according to the pivoting direction of Fig. 5 arranged and the inclined guide block 431 of the second slide 43 is in an inclined direction from bottom to top, from right to left according to the pivoting direction of Fig. 4 arranged so that during the movement of the first slide 42 and the second slide 43 a displacement occurs and thus the first slide 42 can be moved along the longitudinal direction A and the second slide 43 along the transverse direction B.

[0015] To prevent the drive block 5 and the arrow chain 10 from engaging as expected, the arrow chain 10 is provided with several detent recesses 101. As shown in the Fig. 10, Fig. 11 to Fig. As shown in Figure 12, a limiting projection 44 protrudes from the end face of the first slider 42 facing the arrow chain 10. After the user has inserted the arrow chain 10 into the chain hole 2, in addition to engaging one end of the drive block 5 with the arrow chain 10, the limiting projection 44 is also inserted into any one of the multiple detent recesses 101, thus providing an additional limit between the arrow chain 10 and the drive block 5 to ensure that no chain skipping occurs in the arrow chain 10.

[0016] When driving the arrow chain 10, setting it in motion, the primary requirement is that the drive block 5 has an upper section 51 and the arrow chain 10 is provided with several recessed steps 102. The arrow chain 10 is inserted into the chain hole 2 and rests against the upper section 51 by means of any one recessed step 102. When the second slide 43 is moved along the transverse direction B, this recessed step 102 is pushed through the upper section 51, thereby displacing the arrow chain 10. After the displacement of the arrow chain 10 is complete, the drive block 5, together with the chain drive assembly 4, is returned to its original position, and then the upper section 51 is engaged with the next recessed step 102, as shown in the Fig. 4, 5, 10 to 12 are shown.

[0017] The arrow chain 10 consists of several pivotably connected chain links 103 and has a chain-like shape. An insertion block 433 projects from the side of the second slide 43 corresponding to the drive block 5. A first rounded groove 434 is recessed on the top of the insertion block 433. Corresponding to the insertion block 433, the drive block 5 is provided with an elongated sliding hole 52. The insertion block 433 is inserted into the elongated sliding hole 52. Furthermore, an elastic element 6 is arranged between the wall of the elongated sliding hole 52 and the first rounded groove 434, with the two ends of the elastic element 6 bearing elastically against the wall of the elongated sliding hole 52 and the wall of the first rounded groove 434, respectively.After one of the chain blocks 103 has been driven into motion by the drive block 5, the drive block 5 is returned to its original position, bearing against the outer surface of the next chain link 103 as it returns to its original position. At this point, the drive block 5 is moved downwards by a pressure exerted by this chain link 103, thereby compressing the elastic element 6. The drive block 5 is released by the elastic force of the elastic element 6 and moved upwards until the upper section 51 of the drive block 5 is aligned with the reset step 102 of this chain link 103, thus engaging the upper section 51 of the drive block 5 with this reset step 102 and completing the movement of the arrow chain 10, as shown in the figures. Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. 14 shown.

[0018] The forward drive section 12 comprises a pistol housing 122 and an upper pistol cover 123, wherein one end of the upper pistol cover 123 is pivotably combined with the pistol housing 122 and the other end of the upper pistol cover 123 is movable towards or away from the rear support 11. The inner assembly 31 is housed in the pistol chamber 121 of the upper pistol cover 123. The outer assembly 32 is located outside the upper pistol cover 123 and is connected to the inner assembly 31. Furthermore, the end of the rear support 11 connected to the forward drive section 12 is provided with a detent assembly 111, and the end of the upper pistol cover 123 that can be moved towards or away from the rear support 11 is provided with a detent block 124.After the upper pistol cover 123 has been pivoted towards the locking group 111 and covers the pistol chamber 121, the locking block 124 and the locking group 111 are engaged with each other, as shown in . Fig. 2 shown.

[0019] The end of the base 41 located near the inner arrangement 31 has a drive path 45 designed as a recess, as shown in the Fig. 2, Fig. 3, Fig. 4 to Fig. Figure 5 shows that the inner arrangement 31 is partially located in the drive path 45. The outer arrangement 32 moves towards the chain drive arrangement 4 and presses against the first slide 42, allowing it to move along the longitudinal direction A. After the inner arrangement 31 has moved on the first slide 42, the arrow chain 10 is controlled such that a chain link 103 without an arrow body 20 is moved away from the drive path 45, and thus the next chain link 103, which is equipped with an arrow body 20, is moved to the drive path 45, as shown in the figures. Fig. 10, Fig. 11 to Fig. 12 is shown.
