Description
本發明係有關於一種運動器材相關之技術領域,尤其是一種縮小弩弓體積之十字弓。 The invention relates to the technical field related to sports equipment, in particular to a crossbow which reduces the volume of a crossbow.
習知十字弓之結構大體包括一弩身、一橫向設於弩身前端之弩弓、及一連接弩弓兩端之弓弦所組成,詳細結構可參考我國專利公告第I582373號。 The structure of the conventional crossbow generally includes a crossbow body, a crossbow that is laterally provided at the front end of the crossbow body, and a bowstring connecting the two ends of the crossbow. For the detailed structure, refer to my country Patent Announcement No. I582373.
習知之弩弓係橫向凸出於弩身之兩側,而弩弓的長度則形成十字弓的橫向體積,這對背負十字弓的使用者而言會造成很大的困擾,尤其是在樹林或狹小空間內行動時,橫向之弩弓容易阻礙甚至限制使用者移動。 Conventional crossbows are laterally protruding from the sides of the crossbow body, and the length of the crossbow forms the lateral volume of the crossbow, which will cause great problems for users who carry the crossbow, especially in the woods or in small spaces When moving inside, the horizontal crossbow can easily hinder or even restrict the user's movement.
為克服此一缺失,曾有業者提出多折向弩弓之結構教示(如第17至19圖所示),除維持原弩弓可蓄積之力量要求外,更可大幅縮減弩弓橫向之長度,解決習知弩弓橫向體積過大之缺失。 In order to overcome this deficiency, some practitioners have proposed the teaching of the structure of the crossbow (as shown in Figures 17 to 19). In addition to maintaining the power requirements of the original crossbow, it can also greatly reduce the horizontal length of the crossbow to solve the problem. Knowing that the crossbow is too large in size and lacks.
習知多折向弩弓之結構大致包括一多折向弩弓91、兩樞設於多折向弩弓兩端之滑輪組92、一連接各滑輪組92並橫跨弩身93上方之主弦線94、兩連接各滑輪組92且穿伸弩身93之副弦線95。雖說,習知多折向弩弓結構可有效改善弩弓橫向長度之缺失,但卻衍生其它問題,例如:習知滑輪組92包括一輪軸922及同軸連接疊設之
一主弦輪924及一副弦輪926,而由圖中可以看出主弦線94與副弦線95係分別連接不同直徑之主弦輪924及副弦輪926,且輪軸922兩端係樞設於多折向弩弓91未端,故輪軸922需承受主弦線94與副弦線95(主弦輪924及副弦輪926)之拉力與多折向弩弓91之反作用力,導致輪軸922之強度備受考驗。
The structure of a conventional multi-directional crossbow generally includes a
又,多折向弩弓91兩端滑輪組92之主弦輪922與其繞接之主弦線94呈一水平方式連接,並使主弦線94水平的跨設於弩身93上方,而副弦線95為了避免干擾主弦線94之作動,設於主弦線94下方且穿伸弩身93後,以一斜角度θ連接各滑輪組92之副弦輪95。由第18圖中不難看出,副弦線95斜角度θ與水平樞接之副弦輪926連接,而對副弦輪926形成一拉力,導致副弦輪926轉動過程與輪軸922的磨擦力增加,加速輪軸922、副弦輪926、副弦線95等元件磨損;而且副弦線95對副弦輪926之拉力,在副弦線95緊繃時(第19圖),由於斜角度θ加大將更為明顯。
In addition, the
為此,如何能保護輪軸922以及降低副弦線95斜角度θ者,將有助於降低元件磨損之缺失。
For this reason, how to protect the
有鑑於上述習知技藝之問題與缺失,本發明之主要目的,乃在於提供一種縮小弩弓體積之十字弓,透過結構之設計,解決習知十字弓上述之缺失。 In view of the above-mentioned problems and deficiencies of the conventional art, the main purpose of the present invention is to provide a crossbow that reduces the volume of the crossbow. Through structural design, the above-mentioned deficiencies of the conventional crossbow are solved.
