Arrow Magazine Loading Device

Archery equipment can be divided into crossbows and folding bows for users to choose from. The conventional crossbow type can be found in TW M603952, entitled “Automatic arrow up device of crossbow.” This type of crossbow is currently the most popular bow type in the archery field. It can provide users with continuous shooting operation, eliminating the repeated steps of picking up arrows one by one, setting arrows, aiming, and shooting in the early stage.

However, the design of the pressing arm located in the arrow case is the lack of the conventional crossbow in this technology field. The pressing arm is known to press the arrow only by using the elasticity of the spring to push the pressure arm. Nevertheless, the pressing arm only presses the arrow at a single point. When the arrow magazine is filled with arrows, the swing range of the pressing arm will be the largest, and the elastic force accumulation of the spring will also be the largest. As the arrows are launched one by one, the elasticity of the spring will gradually weaken, and the pressing arm will swing back. By the time, the last arrow is about to fall, the elastic force of the spring has long been lost, which also makes it difficult for the pressing arm to push the last arrow body completely. In other words, the falling state of the arrow will not be stable, and some skewing occurs. In addition, during the shooting process from full of arrows in the arrow magazine to the last arrow, due to the large drop change in the elastic force of the pressing arm, the arrow will fall at different points and the friction coefficient will also be different, which will affect the accuracy of shooting.

The main purpose of the present disclosure is to allow every arrow falls smoothly at the same point without inclining during the user operating the crossbow for continuous shooting.

Therefore, in order to achieve the above-mentioned objectives and effects, an arrow magazine loading device is provided. The arrow magazine loading device includes an arrow box case, having an arrow channel through the arrow box case from top to bottom; a loading member, having one end elastically pivot assembled in the arrow channel, and the other end movable pressed against the uppermost arrow among a plurality of arrows in the arrow channel; and a clamping control set, pivotally disposed on the bottom surface of the arrow box case and can be movable opened and closed to clamp the lowermost arrow among the plurality of arrows.

The present disclosure further provides another arrow magazine loading device, disposed on an arrow portion of a bow unit. The arrow magazine loading device includes an arrow box case, having an arrow channel through the arrow box case from top to bottom; a loading member, having one end elastically pivot assembled in the arrow channel, and the other end movable pressed against the uppermost arrow among a plurality of arrows in the arrow channel; and a clamping control set, pivotally disposed on the bottom surface of the arrow box case and can be movable opened and closed to clamp the lowermost arrow among the plurality of arrows.

Referring toto, the present disclosure provides an arrow magazine loading device disposed on an arrow portionof a bow unit. The arrow magazine loading device includes: an arrow box case, having an arrow channelthrough the arrow box casefrom top to bottom; a loading member, having one end elastically pivot assembled in the arrow channel, and the other end movable pressed against the uppermost arrowamong a plurality of arrowsin the arrow channel; and a clamping control set, pivotally disposed on the bottom surface of the arrow box caseand can be movable opened and closed to clamp the lowermost arrowamong the plurality of arrows. In addition to the arrow portion, the aforementioned bow unitfurther includes a slide rail, a launch grip portion, an arrow loading control portionand a string control portionfor launching the arrow. Furthermore, the string control portionis equipped with a bow string set, and the arrow platformis slidable mounted on the slide railand moves forward and backward along the track direction of the slide rail. The arrow box casemoves together with the arrow platform.

According to the above description, when the user continuously shoots the arrow, it is required to first string the bow string setwith a foldable stringing setin the arrow loading control portion. The foldable stringing setmoves toward the bow string set, and the foldable stringing setwill drive the arrow platformand the arrow box caseto move together. Further, the bow unithas two blocking ribsclose to the end of a bow string setand located on both sides of the slide railrespectively. When the arrow box casemoves, it will pass between the two blocking ribs, and part of the clamping control setis more protruding from both sides of the arrow box case, so that the protruding part of the clamping control setwill be pressed by the two blocking ribs, and the clamping control setwill pivot. (As shown inand, in whichshows the pivot opening direction of the clamp arms). After the clamping control setpivots, the clamping to the arrowis released. At this time, the arrowlocated at the lowermost end of the arrow channelcan fall smoothly onto the arrow platform. At the same time, the foldable stringing setwill hook a bow stringin the bow string set, and then the user can use the swing reset of the foldable stringing setto move in the direction opposite to the bow string setuntil the device returns to the original position, thereby a state of waiting to launch is ready that the bowstringis tightened and the arrowhas been stably set up on the arrow platform. After pressing the triggerof the launch grip portion, the bow stringcan be released, allowing the bow stringto eject the arrow. Due to the arrowlands smoothly on the arrow platform, the launched arrowcan remain stable, and the stability of the arrowprovides the shooting accuracy to users.

According to the above description, the detailed technical features of the present disclosure will be further described below. Firstly, the clamping control setis designed with a structure of two clamping arms, as shown in. The clamping control setfurther includes two clamping armspivotally disposed on the bottom surface of the arrow box caseand located on both sides of the arrow channel. Further, when the two clamping armsare not pivoted, one end thereof will protrude from both sides of the arrow box case. The other ends of the two clamping armsare relatively close to each other to clamp the arrowin a stable position and limit the arrowfrom falling into the arrow platform. It mainly allows the arrow box caseto be pressed by the blocking ribsduring the arrow loading operation, thereby allowing the clamping armsto pivot. During the pivot of the two clamping arms, one end of the clamping armsthat was originally clamped the arrowgradually releases the clamping of the arrow. At this time, the arrowis in a stable position because it was previously clamped by the two clamping arms. Therefore, the arrowcan also remain stable when it falls on the arrow platform.

Regarding the structural installation between the clamping armand the arrow box case, the present disclosure mainly forms two mounting partsrecessed in the arrow box casecorresponding to the clamping arms. The two mounting partsare in the form of open groove shape on both sides and are located on both sides of the arrow channel. Each of the clamping armsis movably assembled on each of the mounting parts, respectively. Moreover, each of the two mounting partsincludes an axis columnon the bottom, and each of the two clamping armsincludes an axis holecorresponding to the axis column. The clamping armis assembled on the corresponding axis columnwith the axis hole, so that the clamping armpivots open and close at the mounting partto clamp the arrow. Further, each of the mounting partsincludes a rod body, and each of the rod bodyhas a distance between each of the axis column. Each of the clamping armshas an elliptical holecorresponding to the rod body, and the elliptical hole has an elastic member. When the clamping armis assembled in the mounting part, the rod bodypenetrates the elliptical hole. One end of the elastic memberdisposed against the hole wall of the elliptical holeand the other end of the elastic memberdisposed against the surface of the rod body, so that the elastic memberdrives the clamping armto reset after pivoting. Therefore, the clamping armforms a pivotable operation through the cooperation of the axis columnand the axis hole. Each of the elastic memberprovides the reset of the clamping armafter pivoting, so as to facilitate the continuous operations of clamping and releasing multiple arrowsduring continuous shooting.

In addition, in order to provide the clamping armwith a reliable reset after pivoting without excessive swinging, both ends of the mounting partshas a guide rail, and both ends of the clamping armshave a guide blockcorresponding to each guide rail. When each clamping armpivots, the guide blocksat both ends of the clamping armmove in the corresponding guide rails. Moreover, the bottom side of the arrow box caseincludes a limit grooveand a limit stopperon both sides of the arrow channel. The clamping armhas a convex blockcorresponding to the limit groove, and a limit chutecorresponding to the limit stopper. Through the cooperation of the guide railand the guide block, the clamping armis limited during the pivot movement, so that there will be no deflection problem. When the clamping armis reset after pivoting, the limiting groovecorresponds to the convex block, and the limiting stoppercorresponds to the limiting chuteto prevent excessive swing of the clamping arm. As shown in.

Lastly, in order to reliably clamp the arrow, the present disclosure can stabilize the arrowbefore it falls into the arrow platform. One side of the clamping armused to clamp the arrowfurther includes a fin, and the two finsof the two clamping armsface to each other. The outer periphery of the arrowis clamped by using one side of each fincorresponding to each clamping arm, and each finblocks the falling of the arrow bodywhen each clamping armhas not yet pivoted. In this way, the placement of the arrowcan be maintained in a stable state before the arrowfalls. When the two clamping armspivot to release the arrow, the arrowcan be landed smoothly on the arrow platformand hold for the bow stringto launch the arrow, as shown inand. In the subsequent process of driving the arrow platformand the arrow box caseback to their original positions in preparation for shooting. In addition to using the elastic memberto control the reset of the clamping arm, the blocking ribcan also provide confirmation of the reset of the clamping arm. When the clamping armmoves toward the bow string set, the portion protruding from the arrow box casewill be pressed by the blocking riband thereby pivot. At this time, the outer side of one end of the clamping armwith the finwill be protruded on both sides of the arrow box casedue to the pivot. Therefore, the purpose of the blocking ribcan also be used when the end of the clamping armwith the finis not fully reset during the movement and reset of the arrow box case. The blocking ribcan press against the protruding portion of one end of the clamping armwith the fin. By the blocking rib, the clamping armcan be reliably reset to clamp the arrowand wait for the next stage of arrow dropping operation, which can be seen in. (The arrow indicates the direction of reset of arrow box case).
