Description
本發明係與十字弓相關之技術領域,尤其是指一種十字弓靜音拉弦器結構。 The present invention relates to the technical field related to crossbows, and in particular, to a crossbow silent string puller structure.
按,坊間常見之十字弓結構大致包括一弓身、一組設於弓身一端之弓臂、以及一組設於弓臂兩端之弓弦等構件所組成。 According to reports, the common crossbow structure generally includes a bow body, a set of bow arms located at one end of the bow body, and a set of bow strings located at both ends of the bow arms.
操作時,使用者施力將弓弦拉到上弦位置,配合上箭與擊發等動作來完成十字弓之射箭操作。然,單純依賴使用者手臂力量來拉動弓弦的方式,十分耗費使用者臂力。 During operation, the user exerts force to pull the bow string to the winding position, and completes the crossbow archery operation in conjunction with actions such as cocking and firing. However, relying solely on the strength of the user's arm to pull the bow string consumes a lot of the user's arm strength.
為克服此一缺失,曾有業者提出拉弦機構來解決此一缺失,例如美國專利US6874491、US7100590、US8375928、US8443790、US8689774、US6286496等前案,其結構大致包括一鉤弦器、一捲線器及一搖柄所組成,藉由鉤弦器鉤拉弓弦,配合使用者搖動連接捲線器之搖柄,驅動捲線器作動以收、放鉤弦器兩端之拉繩,同步牽引弓弦至上弦位置。 In order to overcome this shortcoming, some people have proposed string pulling mechanisms to solve this shortcoming, such as US patents US6874491, US7100590, US8375928, US8443790, US8689774, US6286496, etc. The structure generally includes a string hook, a reel and It is composed of a rocking handle. The bow string is hooked by the string hook, and the user shakes the crank handle connected to the reel, driving the reel to retract and release the pull ropes at both ends of the string hook, and simultaneously pulling the bow string to the winding position.
上述前案之捲線器,其原理係透過內部設置之多個齒輪互動,以齒輪比來轉換使用者施予搖柄之驅動力。且為了避免過程中的鬆脫,捲線器內部都會配合一單向機構(例如單向棘輪),但這樣的結構設計,在操作過程中會產生機械噪音,干擾十字弓的使用,尤其是在狩獵活動時。 The principle of the above-mentioned previous reel is to use the gear ratio to convert the driving force applied to the crank handle by the user through the interaction of multiple internal gears. In order to avoid loosening during the process, the reel will be equipped with a one-way mechanism (such as a one-way ratchet). However, such a structural design will produce mechanical noise during operation and interfere with the use of the crossbow, especially during hunting. When active.
有鑑於上述先前技藝之問題與缺失,本發明之一目的,即透過結構創新提供一種十字弓靜音拉弦器結構,俾以克服先前技藝之缺失。 In view of the above-mentioned problems and deficiencies in the prior art, one purpose of the present invention is to provide a crossbow silent string puller structure through structural innovation in order to overcome the deficiencies in the prior art.
為達成上述目的,本發明提出一種十字弓靜音拉弦器結構,係用以收、放一鉤弦器之拉繩,包括一心軸、一搖柄、複數捲線輪、一殼體、一襯套、複數封蓋、複數滾柱、複數限位片、及一離合扳手。該心軸,具一定位軸套。該搖柄,組設於心軸一端。各捲線輪,組設於心軸之兩端供拉繩繞設。該襯套,組設於殼體並具有供心軸穿伸之活動孔,及複數沿活動孔孔壁設置之離合槽。各封蓋套,係銜於心軸外周側,並組設於殼體兩端。各滾柱,分別設置於各離合槽中。各限位片,配置於定位軸套兩端並銜設於心軸與各滾柱外周側。該離合扳手,一端套銜心軸與各滾柱外周側,另端延伸至殼體外側。藉由上述構件之組成,將鉤弦器鉤扣於十字弓之弓弦,配合收、放鉤弦器之拉繩,達成靜音上弦之目的。 In order to achieve the above object, the present invention proposes a crossbow silent string puller structure, which is used to collect and release the string puller of a string hook, and includes a spindle, a cranking handle, a plurality of reels, a shell, and a bushing. , a plurality of covers, a plurality of rollers, a plurality of limit pieces, and a clutch wrench. The mandrel has a positioning sleeve. The crank handle is assembled at one end of the spindle. Each reel is arranged at both ends of the mandrel for winding the drawstring. The bushing is assembled on the housing and has a movable hole for the spindle to extend through, and a plurality of clutch grooves provided along the wall of the movable hole. Each capping sleeve is attached to the outer peripheral side of the mandrel and assembled at both ends of the shell. Each roller is arranged in each clutch groove respectively. Each limiting piece is arranged at both ends of the positioning sleeve and is connected to the spindle and the outer peripheral side of each roller.

是以,上述即為本發明所提供一較佳實施例十字弓靜音拉弦器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 structural components and assembly methods of a crossbow silent stringer according to a preferred embodiment of the present invention. Now, the operating characteristics of the embodiment of the present invention are introduced as follows.
如圖6所示,當使用者有對十字弓90有上弦的需求時,可利用殼體31上之組裝柱312,對應弓身91後端之組裝孔92插置完成組裝。而不使用時也可直接取下收納,避免干擾使用者對十字弓90之射擊。
As shown in FIG. 6 , when the user needs to string the
如圖7、8所示常態下,離合扳手40其離合板件41之延伸部413被彈性元件43拉扯,讓各離合板件41之各橢圓孔412同步夾銜各滾柱35,朝離合槽322一端之約束段322B方向運動。進而使各滾柱35頂抵心軸22之定位軸套24,定位心軸22及其組接之捲線輪28無法朝預設方向樞轉。
As shown in Figures 7 and 8, under normal conditions, the
當使用者欲鉤拉十字弓90之弓弦93時,如圖9、10所示,先扳動離合扳手40之連接件42,使其同步帶動各離合板件41以心軸22為軸心樞轉。過程中,離合板件41之各橢圓孔412同步夾銜各滾柱35兩端,自離合槽322之約束段322B往自由段322A運動。
When the user wants to hook the
當各滾柱35位移到自由段322A時,心軸22即不再被各滾柱35所約束而能自由樞轉,此時使用者便可拉動鉤弦器10同步釋放收捲於捲線輪28之拉繩12至一預設長度,直至鉤弦器10可鉤扣十字弓90之弓弦93為止,便可放開離合扳手40(連接件42),使離合扳手40回到常態下(詳如上所述)。
When each
此時,使用者可搖動組接於心軸22一端之搖柄26,使其驅動心軸22及其組接之捲線輪28同步樞轉,過程中,心軸22(定位軸套24)朝襯套32(離合槽322)之自由段322A方向旋轉,同步牽引各滾柱35朝離合槽322之自由段322A運動,故各滾柱35不會對心軸22(定位軸套24)之樞轉形成阻止,讓心軸22兩端之捲線輪28收捲鉤弦器10之拉繩12,並同步拉動弓弦93朝上弦方向運動,直至弓弦93被拉動到上弦位置。
At this time, the user can shake the rocking handle 26 assembled at one end of the
此時,使用者可再透過扳動離合扳手40之連接件42,讓心軸22處自由樞轉之狀態,好讓使用者將鉤弦器10與弓弦93脫離,再放開離合扳手40同步搖動搖柄26驅動心軸22收捲鉤弦器10多餘之拉繩12,直待鉤弦器10收至預設位置。
At this time, the user can turn the connecting
在上述弓弦93被拉動過程中,會施予鉤弦器10(拉繩12)反作用力,故在上述過程中,搖柄26因故不再對心軸22(定位軸套24)施力時,心軸22(定位軸套24)會因反作用力而反向樞轉,俾以將各滾柱35朝離合槽322之約束段322B運動,藉此達成單向作動之限制,克服先前技藝會有單向齒輪作動噪音等缺失。
When the
另外,如圖11至14所示,上述扳動離合扳手40的過程中,各離合板件41上各橢圓孔412之結構設計,大於限位片36之限位凹槽362,故當離合板件41以心軸22為軸心樞轉時,透過這個間隙差,讓各橢圓孔412孔壁對各滾柱35形成撞擊,俾以讓各滾柱35產生位移,用以降低各滾柱35最大靜磨擦力,讓使用者操作更為省力與順暢。
In addition, as shown in FIGS. 11 to 14 , during the above process of turning the
