Description
本發明係提供一種安全鈎,尤指在符合結構安全要求下,能有效加大鈎口及加長鎖桿之新穎技術,藉此,使整體操作能更為快速方便。 The invention provides a safety hook, in particular, a novel technology capable of effectively increasing the hook opening and lengthening the locking rod in accordance with structural safety requirements, thereby making the overall operation more rapid and convenient.
在攀岩運動、登山運動、建築施工..等等須升降的環境中,皆須藉由安全鈎與安全帶來確保人員的安全。 In rock climbing, mountaineering, construction. . In an environment where lifting is required, safety hooks and safety belts must be used to ensure the safety of personnel.
是以,本發明者便開發出美國第8117721號「吊鈎安全裝置」發明專利案,由於其功效顯著,所以市場反應良好,惟,本發明者仍不以此自滿,發現該案鎖桿在承受側撞力時,只能依靠一支卡掣部將側撞力傳遞至鈎體,容易應力集中,導致鎖桿長度大大受限,所以鈎口便無法相應加大,如此一來,吾人在從事掛鈎或脫鈎動作時,無法一次到位,不僅增加操作之困擾,且會大大影響到產品之價值。 Therefore, the inventors have developed the US Patent No. 8117721 "Hook Safety Device" invention patent, and because of its remarkable effect, the market has responded well, but the inventor still does not complacent, and found that the lock bar is in the case. When receiving the side impact force, the side impact force can only be transmitted to the hook body by a click portion, which is easy to stress concentration, and the length of the lock rod is greatly limited, so the hook mouth cannot be correspondingly enlarged, so that we are When engaging in hooking or unhooking, it cannot be put in place at one time, which not only increases the trouble of operation, but also greatly affects the value of the product.
本發明人有鑑於此,乃精心加以研究改良,終開發出一種能有效加大鈎口及加長鎖桿之本發明,用以使掛鈎或脫鈎操作更為順暢及快速。 In view of this, the present inventors have carefully researched and improved, and finally developed a invention capable of effectively increasing the hook opening and lengthening the locking bar to make the hooking or unhooking operation smoother and faster.
本發明係提供一種安全鈎,其至少包括: 一鈎體,其具有貫穿厚度之鈎孔、第一軸孔、導槽及連通鈎孔內外之鈎口,所述導槽係以第一軸孔為圓心的呈弧狀設置,另設有一突出厚度之卡掣部;一鎖桿,其沿鈎體厚度的設有覆蓋導槽之側板,兩側板更具有與卡掣部匹配之卡緣,且以第一導孔耦接一貫穿導槽之導栓,令鎖桿得繞導栓轉動及沿導槽弧狀擺動的啟閉鈎口,且在鎖桿閉鎖鈎口時,令卡掣部及導栓可形成呆鏈的承受鎖桿側撞力,另,以一主彈簧致動該鎖桿,令卡緣抵接卡掣部的保持鎖桿閉鎖鈎口;以及一控桿,其係以一主軸耦接第一軸孔,另設有供導栓耦接之第二導孔,以便控桿在連動鎖桿繞導栓轉動及沿導槽弧狀擺動時,可帶動卡緣釋放卡掣部,使鎖桿能擺動的開啟鈎口。 The invention provides a safety hook comprising at least: a hook body having a hook hole penetrating through the thickness, a first shaft hole, a guide groove and a hook opening connecting the inner and outer sides of the hook hole, wherein the guide groove is arranged in an arc shape with the first shaft hole as a center, and another protrusion is provided a latching portion of the thickness; a locking bar having a side plate covering the guiding groove along the thickness of the hook body, the two side plates further having a card edge matching the latching portion, and the first guiding hole is coupled to the through guiding slot The guiding bolt is such that the locking rod rotates around the guiding bolt and the opening and closing hook opening which oscillates along the guiding groove, and when the locking rod locks the hook opening, the locking portion and the guiding bolt can form a chain to bear the locking rod side collision a force, and a main spring actuates the lock bar to abut the latching hook of the latching portion of the latching portion; and a lever coupled to the first shaft hole by a spindle, and The second guiding hole is coupled to the guiding pin, so that when the interlocking locking bar rotates around the guiding pin and swings along the guiding groove, the control rod can drive the card edge to release the latching portion, so that the locking bar can swing and open the hook opening.
是以,本發明鎖桿在閉鎖鈎口的承受側撞力時,能透過卡掣部、導栓將該應力傳遞至鈎體,且主彈簧又吸收一部份應力,故而本發明確具有應力分散之優點,以便在符合結構安全要求下,有效加大鈎口及加長鎖桿,用以使掛鈎或脫鈎操作更為順暢及快速。 Therefore, when the locking bar of the present invention is subjected to the impact side of the locking hook, the stress can be transmitted to the hook body through the latching portion and the guiding bolt, and the main spring absorbs a part of the stress, so the invention has the stress. The advantage of dispersion, in order to meet the structural safety requirements, effectively increase the hook and lengthen the lock bar to make the hook or unhook operation smoother and faster.

請配合第六、七及八圖觀之,當吾人第一段壓動控桿40,用以克服第二彈簧48的促動鎖桿30,此鎖桿30係繞導栓34轉動及沿導槽15弧狀擺動,用以帶動卡緣35釋放卡掣部20、卡榫47釋放兩側板32另端,繼之,令保持段3 6能沿卡掣部20的限位移動,用以如第六圖所示的維持鎖桿30閉鎖鈎口110,待吾人持續第二段壓動控桿40,如第七圖所示的令弧段37與卡掣部20相對時,即可以完全釋放鎖桿30,如第八圖所示,吾人便能透過推動鎖桿30,藉由導栓34、弧段37與卡掣部20之雙重引導作用,令鎖桿30能穩定及快速的朝鈎孔11擺動的開啟鈎口110,是以,本發明須透過雙手分別作用控桿40及鎖桿30才可以開啟鈎口110,有效防止誤觸控桿40或鎖桿30而隨便開啟鈎口110之危險情形發生。 Please cooperate with the sixth, seventh and eighth diagrams. When the first stage of the person presses the lever 40 to overcome the actuating lock lever 30 of the second spring 48, the lock lever 30 is rotated around the guide bolt 34 and guided along the guide. The slot 15 is swayed in an arc to drive the card edge 35 to release the latch portion 20, and the latch 47 releases the other ends of the side plates 32, and then the retaining segment 3 is 6 can move along the limit of the latching portion 20 to maintain the lock lever 30 to close the hook 110 as shown in the sixth figure, and wait for the second section to press the lever 40, as shown in the seventh figure. When the arc segment 37 is opposite to the latch portion 20, the lock lever 30 can be completely released. As shown in the eighth figure, the person can push the lock lever 30 by the guide bolt 34, the arc segment 37 and the latch portion 20. The double guiding function enables the locking rod 30 to stably and quickly open the opening hook 110 of the hook hole 11. Therefore, the present invention must be applied to the control rod 40 and the locking rod 30 respectively by the hands to open the hook opening 110, which is effective. A dangerous situation in which the touch lever 40 or the lock lever 30 is accidentally opened to open the hook 110 is generated.
更重要的是,本發明當鎖桿30閉鎖鈎口110的承受側撞力時,能透過卡掣部20、導栓34將該應力傳遞至鈎體10,且主彈簧38及第二彈簧48又能吸收一部份應力,故而本發明確具有應力分散之優點,以便能在符合結構安全要求下,有效加大鈎口110及加長鎖桿30,用以使掛鈎或脫鈎操作更為順暢及快速。 More importantly, the present invention transmits the stress to the hook body 10 through the latch portion 20 and the guide pin 34 when the lock lever 30 locks the receiving side impact force of the hook port 110, and the main spring 38 and the second spring 48 are transmitted. The invention can also absorb a part of the stress, so the invention has the advantages of stress dispersion, so as to effectively increase the hook opening 110 and the extended locking rod 30 in accordance with the structural safety requirements, so as to make the hooking or unhooking operation smoother and fast.
綜上所述,本發明之整體結構特徵,其在現有結構中可以說是前所未見,且為一相當傑出且優異之設計,其在同類產品中均未見有類似之發明或公開之發表,故符合發明專利之申請要件,乃爰依法提出申請。惟以上所述者,僅為本發明之一較佳實施例而已,當不能以之限定本發明實施之範圍,即大凡依本發明申請專利範圍所作之均等變化與修飾,皆屬本發明之範圍。 In summary, the overall structural features of the present invention can be said to be unprecedented in the prior art, and are a rather outstanding and excellent design, and no similar invention or disclosure is found in the similar products. Published, it is in line with the application requirements of the invention patent, which is to apply according to law.
