Abstract
Description
本發明係關於一種手工具,尤指一種螺絲起子,具有帶單向軸承的多個輸入構件以及光學指示器。 The present invention relates to a hand tool, especially a screwdriver, which has a plurality of input members with one-way bearings and an optical indicator.
已知技術之帶有單向結構如棘輪或單向軸承的手工具具有相同的問題:在鎖上的目標物和緊固件之間尚未有足夠的磨擦力時,緊固件會因打滑而無法讓手工具上的單向結構發揮效用。且大多緊固件之螺紋皆為右手螺紋,意指緊固件順時針轉而前進鎖緊,逆時針轉而後退放鬆。對工程師而言是顯而易懂的,但對於一般缺乏空間概念的使用者而言,必需每次嘗試以找到所需方向,造成操作上的麻煩。 Known art hand tools with unidirectional structures such as ratchets or unidirectional bearings have the same problem: when there is not enough friction between the locked target and the fastener, the fastener will slip and fail to allow The one-way structure on the hand tool works. And most of the fasteners' threads are right-handed threads, which means that the fasteners turn clockwise to move forward and lock, and counterclockwise to move backwards to relax. It is obvious and easy to understand for engineers, but for users who generally lack the concept of space, they must try to find the desired direction every time, causing operational troubles.
美國專利號US3742787在1971年7月26日揭示了一個帶有球狀握把及棘輪機構的手工具,其中在兩端有插孔供工具頭***以達到鎖緊及放鬆功能。然而此發明兼具上述兩項問題,即便製造商在兩端以文字標示功能,這樣的方法不夠直覺,並且破壞美觀。 US Patent No. US3742787 on July 26, 1971 disclosed a hand tool with a spherical grip and a ratchet mechanism, in which there are sockets at both ends for the tool head to insert to achieve the locking and loosening functions. However, this invention has both of the above-mentioned problems. Even if the manufacturer uses text to mark the function at both ends, this method is not intuitive and ruins the aesthetics.
本發明提供了一種手工具,透過多個含有單向軸承的輸入構件解決了緊固件的打滑問題,並且用光學指示器解決了識別方向的問 題,該光學指示器用移動箭頭示出方向。當用戶的手握住手工具並且箭頭指向外側時,整個組件僅傳遞順時針旋轉,從而拴緊緊固件,當用戶用左手握住主手柄,窗口朝上,右手握住後子手柄並反覆轉動,順時針轉動時箭頭向外移動,逆時針轉動時停止。 The present invention provides a hand tool, which solves the problem of fastener slippage through a plurality of input members containing one-way bearings, and uses an optical indicator to solve the problem of identifying direction. Question, the optical indicator shows the direction with a moving arrow. When the user's hand holds the hand tool and the arrow points to the outside, the entire assembly only transmits clockwise rotation to fasten the fasteners. When the user holds the main handle with the left hand, the window faces upwards, and the right hand holds the rear handle and rotates repeatedly , The arrow will move outward when turning clockwise, and stop when turning counterclockwise.
另一方面,當用戶的手握住手工具並且箭頭指向內側時,整個組件僅傳遞逆時針旋轉,從而退出緊固件,當用戶用左手握住主手柄,窗口朝上,右手握住後子手柄並反覆轉動時,逆時針轉動時箭頭向內移動,順時針轉動時停止。 On the other hand, when the user's hand holds the hand tool and the arrow points to the inside, the entire assembly only transmits counterclockwise rotation, thereby exiting the fastener. When the user holds the main handle with the left hand, the window faces upwards, and the right hand holds the rear handle When it rotates repeatedly, the arrow moves inward when it rotates counterclockwise, and it stops when it rotates clockwise.

參照第1~3圖,本發明手工具的第一實施例描述如下。本手工具包括軸10、主手柄20、透鏡30、兩個子手柄40、兩個組裝構件50、多
個離合構件60和工具構件70。在該實施例中,離合構件60表示為單向軸承。在其他實施例中,離合構件60可以由集成的單向軸承代替。每個離合構件60具有外表面62、前側64、通道66和後側68,其中外表面62通常為多邊形柱體。軸10通常為圓柱形,具有圓柱面12,其上具有螺旋圖案122,並且兩端有孔14,在其內部具有磁體16,用於固定工具構件70。工具構件70具有工具側72以及柄部74,工具側72用於接合緊固件80,柄部74通常為多邊形柱體,用於***軸10的一個孔14中。本實施例中的緊固件80表示為螺釘。透鏡30由透明材料製成,並具有外表面32、第一內表面34、第二內表面36和前表面38,子手柄40通常為圓柱形,具有外表面42、凹槽44、通道46和凹槽48。組裝構件50通常為硬幣形狀,在其中心具有孔52。主手柄20通常為多邊柱形,具有外表面22、兩個凹槽24、通道26和窗口28。
Referring to Figures 1 to 3, the first embodiment of the hand tool of the present invention is described as follows. The hand tool includes a
在該實施例中,兩個離合構件60***主手柄20的兩個凹槽24中,其前側64面向相同方向。接著,軸10***主手柄20的通道26以及兩個離合構件60的通道66中。透鏡30安裝在窗口28中,其外表面32與主手柄20的外表面22對齊並合併。兩個子手柄40安裝在整個組件上,其凹槽44朝外,軸10位於其通道46內,此時,兩個子手柄40與主手柄20略微接觸,軸不突出子手柄如。另外兩個離合構件60***兩個子手柄40的凹槽44中,其前側64面向與主手柄20內部的兩個離合構件60相同的方向,同時,軸10穿過兩個其中的通道66。接著,兩個組裝構件50安裝在軸10上,其孔52緊緊地套在其上,而兩個組裝構件50都沒入到凹槽48中並完成了該實施例的組裝。工具構件70可以***其中一個孔14中並且透過磁體16定位。
In this embodiment, the two
參照第4圖,本發明手工具的光學指示器之原理描述如下。
通過將軸10和透鏡30分離出第一實施例,螺旋圖案122的部分圖像直接向前進入第一內表面34並最終由外表面32顯示,其中該部分圖像向右偏移;在另半邊,透鏡30的左側部分由第二內表面36和外表面32的左部分形成具有聚焦線362的垂直凸透鏡(如圖4中的點所示),該聚焦線362在第二內表面36和圓柱面12之間。其中螺旋圖案122的部分圖像首先收縮到聚焦線362中,水平反轉,並投影到第二內表面36上,最終由外表面32顯示,其中該部分圖像向左側部分移位並且被反轉。通過組合由外表面32顯示的所述兩個圖像,成為箭頭322。由於軸10的旋轉受到離合構件60的限制,軸只能逆時針旋轉,因此,螺旋圖案的局部圖像僅向上移動,從而箭頭在其指向的方向上向前移動。
Referring to Fig. 4, the principle of the optical indicator of the hand tool of the present invention is described as follows.
By separating the
如第5圖所示,當手工具由使用者的手握住並且箭頭指向外時,整個組件僅傳遞順時針旋轉而拴緊緊固件。當使用者用左手握住主手柄20、窗口28朝上,右手握住後子手柄40並反覆轉動,箭頭在順時針轉動時向外移動,在逆時針轉動時停止。
As shown in Figure 5, when the hand tool is held by the user's hand and the arrow points outward, the entire assembly only transmits clockwise rotation to tighten the fastener. When the user holds the
如第6圖所示,當手工具由使用者的手握住並且箭頭指向內時,整個組件僅傳遞逆時針旋轉而退出緊固件。當使用者用左手握住主手柄20、窗口28朝上,右手握住後子手柄40並反覆轉動,箭頭在逆時針轉動時向內移動,在順時針轉動時停止。
As shown in Figure 6, when the hand tool is held by the user's hand and the arrow points inward, the entire assembly only transmits counterclockwise rotation and exits the fastener. When the user holds the
參照第7-8圖,第二實施例是第一實施例的變型,具有集成離合機構,描述如下。根據第一實施例,離合構件60集成到軸10中並且由軸10的圓柱面12上的多個離合凹部18以及其中的多個滾柱610代替。在該實施例中,主手柄20中的凹槽24由通道26的延伸部分代替,子手柄40中的凹
槽44由通道46的延伸部分代替。離合凹部18允許滾柱610在一個方向上自由旋轉,而在另一個方向上,滾柱610向外移動並鎖定通道26或通道46,其中限制了主手柄20或子手柄40與軸10之間的相對旋轉。因此,整個組件具有與第一實施例相同的特徵。
