Description

1254105 玖、發明說明：
I：發明戶斤屬之技術領域I 本發明係大致有關於一種具螺紋繫件，且特別是有關 於一種與易碎材料共同使用的具螺紋繫件。 發明背景 螺絲已存在多年且依據提供一楔緊作用之傾斜平面之 原理來迫使該螺絲之頭部螺入基材中，現已發展出多種使用於 不同材料之不同螺絲。 10 用以將其基材固定連接於一低強度易碎材料之繫件通常 需要某種供該繫件使用之支持材料，例如，若為乾砌牆，則通 常使用一金屬或木製銷釘。若為磚石結構，則藉由一在一預先 鑽出之水泥孔中攻出螺紋時用於將材料扣持在該螺紋間之螺 紋結構，可將自攻型繫件確實地固持在該水泥孔中。這種磚石 15 結構繫件之一例為Giannuzzi之美國專利第5,957,646號。 所需要的是一種可以與包括但不限於易碎材料之多種材 料共同使用，同時製造成本低廉之螺絲型繫件。 【發明内容】 發明概要 20 本發明之繫件可達成前述需求且克服先前技術之缺 點。在一實施例中，一金屬繫件包括一具有大致一定直徑 之金屬桿，一形成在該桿上之螺旋螺紋，其中該螺紋直徑 對該桿直徑的比例至少為1.5 : 1且該螺旋螺紋係以在0.5至 1.0cm間的間隔分開。該繫件可包括一形成在該桿上且接近 1254105 该碩部並遠離該尖 質上小於該第疋歡’二螺紋具有實 弟直狴之第二直徑。 在另一貫施例中，— 括提供—金屬 彳用以形成—金屬繫件之方法包 部且藉由軋制开 1'驟’該金屬桿在一第一端處具有-頭 表面，盆中—螺旋螺紋與多圈連續螺紋間之不平坦 螺距在05盘】of文直從與該桿直徑之比例至少為Μ ·· 1且 靠、2 之間。在這方法巾，«在該桿上形成- #近辆部H紋的另-步驟。 10 15 二將：構物支持在 之自Α•楗供一包括一頭部與桿 主直^ H ’且該桿具有一次直徑與-主直徑，該 直;=ΓΜ在該桿上之螺旋螺紋來界定，其中該主 該= 比例至少是。:1;及驅使該繫件進入 X τ料使传錢件與結構物完全由該易碎材料支持 二其中該繫件係石膏板與碑石材料之任一材料。該磚石材 枓可以是混凝土、磚塊與石塊中之任一者。 本毛月之其他4寸敛與優點將在以下說明中提出且可由 其了解’本發明之特徵與優點可以藉由在書面說明及盆申 請專利範圍與附圖中所特別指出之該等結構物與方法來實 現與獲得。 、 在此應了解的是前述_般性說明與以下詳細說明係舉 例與說明用的’並且只是要提供進_步之說明而不是要限 制如申請專利範圍中所界定之範疇。 圖式簡單說明 20 1254105 其長向上大略是一致的，而在靠近尖端16處具有略小一 度。頭部12可形成有多數供一如+字頭螺絲起子之螺絲 預入的溝槽15，或者頭部可以容納—平頭螺絲起子或= 六角或方形驅動器，或該頭部可以是一類似一螺栓之二 5頭，特別是用以懸掛為相當重之物體的擱架等。同日士角 頭部可以用以一鉤或類似裝置來替代。 泫 請參閱在第1圖中所標示之螺紋2〇之部份22，螺会 係分別以上與下倒角表面24與26來說明，該算t金' 2〇 〜寸Η下倒角 表面24與26可以一大致為1〇度之角度延伸。一粗化 1〇 3〇亦可延伸在桿14上，表面3〇之特徵在於各種與形成 螺紋之相當平滑表面相反的凸脊、刻痕、凸塊及/戈凹样等 如圖所示，表面30係設置在多圈連續螺紋2〇之間且可:。 在該桿之一部份或長向上，一第二螺紋亦可形成在該浐^ 15上。在較佳實施例中，第二螺紋40係形成在靠近碩部U声4 且圍繞該桿大約360度。螺紋40亦可形成為圍繞該桿大於= 小於360度，螺紋40之高度係以大致小於螺紋2〇之高产為 佳。 、、 在石賞板或乾石切牆應用中’可了解本發明之繫件停於 2白知螺絲之處，在一習知螺絲中，相當細（即小的主直徑對 一人直杈之比例）與相當密螺距使得與螺紋結合之牆的部份 相對於該預成形孔之尺寸顯得相當小，因此，在該牆中之 固持強度是小的。相反地，與繫件1〇之螺紋結合之材料量 $於該孔之尺寸而言係相當多的，藉由結合大量材料與該 等螺紋，在該材料中可達成一更確實之固持。藉由以金屬 1254105 製成該繫件，相同之繫件亦可被插入混凝土或相當硬之材 料中。在混凝土、磚塊或石塊應用中，在該材料中形成有 一具有與該桿次直徑大致相當之直徑的孔，接著將該繫件 插入該孔，且該等螺紋在該孔中形成螺旋溝槽。當該繫件 例如，以一驅動工具，迫入該孔中時，材料由該牆斷裂且 被抓握在該等螺紋之間。 10 在本發明之製造一金屬繫件之方法中，一螺紋係以由 一冷軋法形成為佳，依據這方法，該乾砌牆繫件之桿係在 兩螺紋成形模之間軋製，藉此產生該螺紋。或者，該繫件 累、、文可由麵^法形成，或經由一車床加工形成。在一較 仏K 例中，該軋製法形成一具有一如一起形成螺紋加之 絮件10之表面24與26之上與下倒角表面之螺紋，亦可藉由
15 20 该軋製法來，例如壓成片狀，以產生粗化之表面3〇。當 於±累紋形成期間在該等模之間受到擠壓時，材料將: :均勻地流動，這將在該等螺紋成形體之間形成一不平』 =粗，之表面。這*均句材料流之效應在本發明之繫件 者’而這在以—軋製法製造時會在螺紋成形體之I 主/不平坦或粗化之表面。另，在不偏離本發明之 $ >下/亦可使用所屬技術領域中已知之其他方法以> 遠寺螺:之間產生-粗化或不平坦之表面。 第一也相對轉動模係定位在靠近頭部12處以形」 成如:⑽’ _红螺紋4Q延伸圍繞桿丨4大約360度。^ 形成3止#近頭部12之椁14之上部在❹軋製法時如 μ;:且螺距及/或高主/次直經比例所需之力量而彎曲、
10 1254105 一較佳實施例中，可使用一如螺紋成形模之相對轉動模以 抵消當螺紋20形成時桿14之上端彎曲之傾向。螺紋40之深 度不必是一個很大的值並且可以等於一不具有相當大之固 定能力之相當不明顯螺紋深度。第二螺紋40亦可依需要延 5 伸小於或大於360度。 雖然前述說明係有關於本發明之較佳實施例，但應注 意的是所屬技術領域中具有通常知識者可了解其他各種變 化與修改，且可以在不偏離本發明之精神或範疇之情形下 進行各種變化與修改。 10 【圖式簡單說明】 第1圖是具有本發明之原理之乾砌牆繫件之側視圖。 第2圖是第1圖之乾砌牆之俯視圖。 第3圖是第1圖之乾砌牆之仰視圖。 【圖式之主要元件代表符號表】 10…繫件 30…粗化表面 12…頭部 40…第二螺紋 14·…桿 15…溝槽 16...尖端 20...螺紋 22...螺紋部份 24...上倒角表面 26...下倒角表面
