Description

十字弓扳機結構 Crossbow trigger structure

本發明係有關於一種十字弓相關之技術領域，尤指在上緊弓弦的過程中，即可自動上保險，且需確實將弓箭放置完成後，方能解開保險進行射擊之十字弓扳機結構。 The present invention relates to a crossbow related technical field, and in particular, it can be automatically insured during the process of tightening the bowstring, and the crossbow trigger structure can only be unlocked for firing after the bow and arrow have been put in place. .

按習知十字弓之結構，如我國專利第207344號前案可知，其包含括一弩身、一橫設於弩身前端之弩翼、一連接弩翼兩端之弓弦、以及一銜設於弩身並與弓弦互動之拉弦器。透過拉弦器牽拉弓弦形成緊繃，並與弩身之弩機互動。 According to the structure of the conventional crossbow, as known in the former case of Chinese Patent No. 207344, it includes a crossbow body, a crossbow wing horizontally arranged at the front end of the crossbow body, a bowstring connecting the two ends of the crossbow wing, and a link between A crossbow puller that interacts with the bowstring. Pull the string through the stringer to create tension and interact with the crossbow crossbow machine.

然而，周知十字弓與一般弓箭射出的箭矢相同，皆具有一定的殺傷力，若在操作的過程中稍有不慎，很容易導致使用者或他人的受傷。然而，目前坊間常見之十字弓多不具有保險裝置，容易發生誤擊的事故。 However, the well-known crossbow is the same as the arrows fired by ordinary bows and arrows, and both have a certain lethality. If they are slightly careless during the operation, it may easily cause injuries to users or others. However, most of the cross bows currently in the market do not have a safety device, which is prone to accidental accidents.

為此，業者雖提出結構改良，於十字弓上設置保險裝置，但其保險裝置之設計乃在使用者將弓弦拉緊而卡扣在弩身弩機時，再啟動此一保險裝置。由於無法自動觸發保險裝置，常會有使用者忘記的情況發生，導致此一保險裝置形同虛設。 For this reason, although the industry proposes to improve the structure and install a safety device on the crossbow, the safety device is designed to activate this safety device when the user tightens the bowstring and snaps it on the crossbow crossbow machine. Because the safety device cannot be triggered automatically, there are often situations where the user forgets it, which results in this safety device being useless.

另外，也由於習知保險裝置，都只有單一結構並不具有多重保險的功能，無法有效的達到保險防護之效益，故實有其改善之必要。 In addition, because the conventional insurance devices have only a single structure and do not have multiple insurance functions, the benefits of insurance protection cannot be effectively achieved, so it is necessary to improve them.

有鑑於上述習知技藝之問題與缺失，本發明之主要目的，乃在於提供一種十字弓扳機結構，藉由結構的設計，克服習知拉十字弓保險機制上的缺失與不便。 In view of the problems and deficiencies of the above-mentioned conventional techniques, the main object of the present invention is to provide a crossbow trigger structure, which overcomes the lack and inconvenience of the conventional crossbow insurance mechanism by designing the structure.

根據本發明上述目的，提出一種十字弓扳機結構，係設置於一十字弓之弩身，作為約束十字弓之弓弦與弩身上之弓箭，其包括一弩機盒、一扳機組、一扳機保險組、及一防空弦保險組。該弩機盒與弩身連接，提供一容置空間。該扳機組，係分別容置於弩機盒與弩身，以約束弓弦作動。該扳機保險組及該防空弦保險組，係分別容置於弩機盒並與扳機組互動，選擇性的約束扳機組之作動。藉由上述構件之組成，於上緊弓弦的同時一併觸發扳機保險組及防空弦保險組，俾以形成自動上鎖確保十字弓使用之安全。 According to the above object of the present invention, a crossbow trigger structure is provided, which is arranged on a crossbow crossbow body and serves as a bow and arrow that constrains the crossbow's bowstring and crossbow body. , And an air string insurance group. The crossbow box is connected to the crossbow body to provide a space for accommodation. The trigger set is housed in the crossbow box and the crossbow body respectively, to restrain the bowstring from operating. The trigger insurance group and the air string insurance group are respectively housed in a crossbow box and interact with the trigger group, selectively restraining the trigger group action. With the composition of the above components, the trigger insurance group and the air string insurance group are triggered together when the bowstring is tightened, so as to form an automatic lock to ensure the safety of the crossbow.

是以，上述即為本發明所提供一較佳實施例十字弓扳機結構各部構件及組裝方式之介紹，茲再將本發明之實施例作動特點介紹如下。 Therefore, the above is an introduction to the components and assembly methods of the crossbow trigger structure of a preferred embodiment of the present invention, and the operating characteristics of the embodiments of the present invention are described below.

<上弦且同步上鎖> <Wind and synchronized lock>

請參閱第9至13圖所示，透過弩身91之拉弦器(圖中未示，習知技藝)，將弓弦92經箭尾剖槽123、143拉進弩機盒10內，並推抵勾弦爪27之止擋部274，以連動勾弦爪27以第三樞接柱1273為中心擺動；過程中，爪臂271相反於爪勾272之另一端，向上位移並壓縮第三扳機復位件223，且不再頂抵扳機卡掣件26之第一支臂261，讓扳機卡掣件26受第二扳機復位件222之推頂，而以第二樞接柱1272為中心樞轉回復，讓扳機卡掣件26之第三支臂263壓抵於第二限位端面1262與扳動件24(T型本體242水平段一端)，更讓扳機卡掣件26之第一支臂261對爪臂271朝下端面形成頂抵。 Please refer to Figures 9 to 13 to pull the bowstring 92 into the crossbow box 10 through the tail slits 123 and 143 through the puller of the crossbow body 91 (not shown in the art). Abutting on the stopper portion 274 of the hook claw 27, the linked hook claw 27 is swung around the third pivot post 1273; in the process, the claw arm 271 is opposite to the other end of the claw hook 272, and is displaced upward and compresses the third trigger The reset member 223 is no longer pressed against the first arm 261 of the trigger latching member 26, so that the trigger latching member 26 is pushed by the second trigger resetting member 222, and pivots with the second pivot post 1272 as the center. Reply, let the third arm 263 of the trigger latch 26 press against the second limit end face 1262 and the trigger 24 (one end of the horizontal section of the T-shaped body 242), and let the first arm of the trigger latch 26 The 261 pair of claw arms 271 form abutment toward the lower end surface.

另外，爪臂271鄰近爪勾272端則向下擺動，推移保險撥塊35之鎖片部351，讓保險撥塊35被推動自解鎖位置移動到上鎖位置，並使滑片部352朝下端面之第一定位槽3522與限位件34分離，而改以第二定位槽3524與限位件34 卡合，此時保險撥塊35之鎖片部351位於扳動件24第一擋部244上方。 In addition, the claw arm 271 swings downward near the end of the claw hook 272, and pushes the locking piece portion 351 of the safety pad 35, so that the safety pad 35 is pushed from the unlocked position to the locked position, and the slide piece 352 faces downward The first positioning groove 3522 on the end face is separated from the limiting member 34, and the second positioning groove 3524 and the limiting member 34 are changed instead. At this time, the locking piece portion 351 of the safety dial 35 is located above the first stop portion 244 of the trigger member 24.

將拉弦器回位，讓弓弦92勾卡於勾弦爪27之爪勾272上，由於相異之另一端受扳機卡掣件26之第一支臂261之頂抵無法回復釋放弓弦92。至此已完成上弦且同步自動上鎖之動作。因為保險撥塊35之鎖片部351位於扳動件24第二擋部246上方，使用者無法扣下扳機件21連動扳動件24扳動。 Return the string puller to hook the bow string 92 on the hook 272 of the hook claw 27. Since the other end is pressed against the first arm 261 of the trigger latch 26, the bow string 92 cannot be released. This completes the winding and automatic locking operation. Because the locking piece portion 351 of the safety dial 35 is located above the second stop portion 246 of the trigger member 24, the user cannot pull down the trigger member 21 to link the trigger member 24 to trigger.

緃始故意將保險撥塊35自上鎖位置移動到解鎖位置時，由於防空弦保險組之壓塊44被壓塊復位件42推頂至與扳動件24(第一擋部244)運動路徑上，致使扳動件24依然無法被扳機件21連動。 When the lock block 35 was intentionally moved from the locked position to the unlocked position, the pressure block 44 of the air string insurance group was pushed up by the block reset member 42 to the movement path of the trigger member 24 (the first stop 244). The trigger member 24 is still unable to be linked by the trigger member 21.

<上箭並解鎖防空弦保險組> <Up Arrow and Unlock Air Defense String>

請參閱第13至14圖所示，將弓箭93滑設於弩身91之箭槽911，並讓弓箭93之箭尾經箭尾剖槽123、143及箭尾容槽122、142***弩機盒10內，於弓箭93之箭尾進入弩機盒10過程中，會同步壓抵防空弦保險組之壓塊44，讓壓塊44以第四樞接柱1274為中心樞轉，並壓縮壓塊復位件42，以避開扳動件24(第一擋部244)運動路徑。 Please refer to Figures 13 to 14, slide the bow and arrow 93 in the arrow slot 911 of the crossbow body 91, and insert the tail of the bow and arrow 93 into the crossbow machine through the tail slits 123 and 143 and the tail grooves 122 and 142. In the box 10, when the tail of the bow and arrow 93 enters the crossbow box 10, it will simultaneously press against the pressure block 44 of the air string insurance group, so that the pressure block 44 pivots around the fourth pivot post 1274, and compresses the pressure. The block restoring member 42 is configured to avoid the movement path of the triggering member 24 (the first stopper 244).

<解鎖扳機保險組並射擊> <Unlock trigger insurance and fire>
