Description

Tethered fastener

本創作係關於繫留緊固件，且更特定言之，本創作係關於繫留柱塞及繫留螺釘。This creation is about tethered fasteners and, more specifically, the tethered and captive screws.

繫留緊固件(諸如繫留螺釘及繫留柱塞)一般用於將一第一面板附接至一第二面板或框架，其中期望在無需鬆開硬體之零件之情況下使緊固件保持於適當位置中。例如，繫留緊固件可安裝於一第一面板上，使得即使當緊固件(諸如一螺桿之螺紋)完全脫離第一面板附接至其之一第二面板時，緊固件保持附接至面板。繫留緊固件可用於電子產業中。在某些應用中，當打開或移除門或蓋且在此等門或蓋後面存在一危險電壓時，政府法規可要求藉由使用一工具而打開或移除門或蓋。然而，為方便工人，亦可期望能夠用手擰緊繫留緊固件。Tethered fasteners, such as captive screws and mooring plungers, are typically used to attach a first panel to a second panel or frame where it is desirable to hold the fasteners without loosening the hardware components In the right place. For example, the tether fastener can be mounted to a first panel such that the fastener remains attached to the panel even when the fastener (such as a thread of a screw) is completely detached from the first panel attached to one of the second panels . Tethered fasteners can be used in the electronics industry. In some applications, when a door or cover is opened or removed and a dangerous voltage is present behind the door or cover, government regulations may require opening or removing the door or cover by using a tool. However, it is also desirable to be able to hand tighten the tethered fasteners for the convenience of the worker.

本申請案係關於且主張2016年2月3日申請之名稱為「CAPTIVE FASTENER」之美國臨時申請案第62/290,682號之優先權，該案之全文出於所有目的以引用之方式併入本文中。儘管本文中參考特定實施例來繪示及描述本創作，但本創作不意欲受限於所展示之細節。確切而言，可在不背離本創作之情況下於申請專利範圍之等效物之範疇及範圍內對詳細作出各種修改。繫留緊固件可用於致力於耦合兩個或兩個以上物件之各種領域中。作為一實例，繫留緊固件通常用於將一蓋耦合至一表面及/或一面板及框架。儘管本文中相對於將一面板耦合或緊固至一框架而討論本創作之實施例，但熟習技術者將意識到，繫留緊固件可有利地用於將其他物件或特徵耦合或緊固在一起。根據本創作之態樣之繫留緊固件可耦合或附接至一或多個物件，使得相對於該等物件之一者鬆開繫留緊固件不會自所有該等物件拆離繫留緊固件。大體上參考圖式，一繫留緊固件10大體上包含一螺柱100，其包含一頭部110及自頭部110沿螺柱100之一縱軸線102延伸至螺柱100之一遠端104的一桿身120。桿身120具有一緊固件部分140。一止動環400附裝至螺柱100之桿身120且與螺柱100之遠端104間隔開。一旋鈕200界定一孔204，螺柱100之頭部110至少部分安置於由旋鈕200界定之孔內。一套圈300界定自套圈300之一近端320沿套圈300之一縱軸線302延伸至套圈300之一遠端306的一通道304，且螺柱100安置於套圈300之通道304內且可沿螺柱100之縱軸線102相對於套圈300移動。套圈300之一近端部分320具有朝向螺柱100之縱軸線102延伸之一向內凸緣322。套圈300之近端部分320之向內凸緣322經定位以在螺柱100相對於套圈300位移之後嚙合止動環400。套圈300之向內凸緣322經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102在螺柱100之桿身120之一近端部分122處的不對準。止動環400經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102在螺柱100之桿身120之一遠端部分126處的不對準。參考圖1，提供根據本創作之一實施例之用於附接至一面板之繫留緊固件10。一般而言，繫留緊固件10包含一螺柱100、一旋鈕200、一套圈300及一止動環400。螺柱100具有一縱軸線102，一遠端104沿此縱軸線102與一近端106間隔開。螺柱100亦包含一頭部110及自頭部110延伸之一桿身120。頭部110具有界定一幾何形狀(諸如一圓形、正方形、三角形、六邊形、八邊形或其他幾何形狀)之一橫截面積112。儘管橫截面積112在沿縱軸線102之各種點處界定一圓形(如圖2中所繪示)，但橫截面積112亦可沿縱軸線102界定非幾何形狀。例如，頭部110可經構形以具有一非幾何形狀且因此亦可具有一非幾何形橫截面積。另外或替代地，橫截面積112可沿螺柱100之縱軸線102變動。例如，頭部110可包含一突出部114，其具有含不同於頭部110之橫截面積112之至少一尺寸的一橫截面積116。同樣地，頭部110可包含一凹部或一凹口，其具有含不同於頭部110之橫截面積112之至少一尺寸的一橫截面積。如下文將進一步討論，頭部110可經構形以具有由旋鈕200之一或多個對應突出部、凹口及/或凸緣緊固之突出部114及/或一凹口。參考圖2，頭部110在螺柱100之近端106處界定一螺絲起子118。然而，根據一實施例，螺柱100之頭部110未界定螺絲起子118。螺絲起子118可經構形為促進螺柱100之頭部110與一工具嚙合之一凹腔及/或一突出部，其能夠藉由旋轉工具而旋轉螺柱100。例如，螺絲起子118可自螺柱100之近端106向內延伸以界定一凹腔或自螺柱100之近端106向外延伸以界定一突出部。螺絲起子118可經構形以嚙合具有(例如)飛利浦(Philips)尖端、十字型(Frearson)尖端、梅花型(Torx)尖端、口字型尖端、一字型尖端之一工具或另一類型之工具。螺柱100包含自頭部110沿螺柱100之縱軸線102延伸至螺柱100之遠端104的一桿身120。儘管在圖3所繪示之實施例中桿身120具有一大體上呈圓柱形之形狀，但桿身120可具有其他幾何形狀(例如矩形、三角形或其他幾何形狀)或非幾何形狀(其包含一或多個筆直部分及/或圓形部分)。桿身120包含一近端部分122及一遠端部分126，其中遠端部分126比近端部分122更進一步與頭部110間隔開。桿身120亦包含經構形以使螺柱100能夠緊固至一或多個物件(諸如面板12及14)之一緊固件部分140。緊固件部分140可包含具有一小直徑144及一大直徑147之螺紋。另外或替代地，緊固件部分140可包含經構形以嚙合一或多個物件(例如面板12及14)之一或多個凹槽及/或突出部。根據一實施例，緊固件部分140具有至少一垂直延伸凹槽及依一角度自其延伸之另一凹槽，使得繫留緊固件10經構形以在螺柱100旋轉四分之一圈之後緊固至一或多個物件(例如面板14)。儘管在圖2至圖4B中緊固件部分140與螺柱100之遠端104間隔開，但緊固件部分140可延伸至遠端104。此外，緊固件部分140可延伸至頭部110。例如，在一實施例中，緊固件部分140自螺柱100之遠端104沿桿身120延伸至頭部110。桿身120之遠端部分126可與螺柱100之遠端104間隔開或延伸至螺柱100之遠端104。另外及/或替代地，緊固件部分140可安置於桿身120之遠端部分126上。遠端部分126具有可不同於桿身120之近端部分122之橫截面積124的一橫截面積128。例如，遠端部分126可具有小於桿身120之近端部分122之橫截面積124或其直徑的一橫截面積128或其直徑。在一實施例中，遠端部分126之橫截面積128或其直徑小於近端部分122沿緊固件部分140的橫截面積124或其直徑且等於或近似等於近端部分122沿介入於近端部分122與緊固件部分140之間之桿身120之區段的橫截面積124。根據其中緊固件部分140包含螺紋的另一實施例，遠端部分126之橫截面積128可等於或小於緊固件部分140之螺紋之一小直徑144。遠端部分亦可界定經調適以接納一止動環(例如止動環400)之一軸肩部分130。例如，在一實施例中，軸肩部分130包含經調適以用於附接一止動環之一選用滾紋或其他表面特徵。軸肩部分130之橫截面積132可不同於遠端部分126之橫截面積128。例如，軸肩部分130之橫截面積132可小於介入於軸肩部分130與近端部分122之間之遠端部分126之橫截面積128之一區段，使得一止動環被阻止沿桿身120朝向頭部110滑動超過軸肩部分130。桿身120亦可具有介入於螺柱100之遠端104與緊固件部分140之遠端148之間之一引導部分150。引導部分150可經構形以促進緊固件部分140與一或多個物件(例如一配合面板之一緊固件部分)對準。若緊固件部分140包含螺紋，則引導部分150可具有等於或小於緊固件部分140之橫截面積146及/或螺紋之一小直徑144的一橫截面積152。另外或替代地，引導部分150之橫截面積152或其直徑可小於或等於遠端部分126之橫截面積128、近端部分122之橫截面積124及/或其等之任何直徑。繫留緊固件10亦包含附裝至螺柱100之桿身120且與螺柱100之遠端104間隔開之一止動環400。例如，止動環400可沿遠端部分126及/或軸肩部分130附裝至桿身120。止動環400可藉由機械方法(諸如壓配合、箝夾、焊接、螺合、楔入或其類似者)或非機械方法(諸如，藉由施加黏著劑或其類似者)而附裝至桿身120。根據一實施例，藉由沿軸肩部分130安置之一滾紋而消除或抑制止動環400相對於螺柱100之桿身120移動。在另一實施例中，止動環400係螺柱100之桿身120之一整合延伸部。止動環400可朝向套圈300延伸。在一實施例中，止動環400可視情況經構形以接觸套圈300。繫留緊固件10進一步包含一旋鈕200，其可具有與螺柱100之縱軸線102對準之一縱軸線。旋鈕200界定一孔204。螺柱100之頭部110至少部分安置於由旋鈕200界定之孔204內。在一實施例中，旋鈕200之孔204自旋鈕200之一遠端206延伸至旋鈕200之一近端208。在另一實施例中，旋鈕200之孔204自旋鈕200之遠端206延伸至介入於遠端206與近端208之間之旋鈕200之一部分，使得螺柱100之近端106由旋鈕200圍封。螺柱100之頭部110可緊固於旋鈕200之孔204內，使得頭部110可在孔204內移動及/或旋轉。然而，在一實施例中，頭部110固定地緊固於頭部110內，使得頭部110相對於旋鈕200固定。例如，頭部110可固定地緊固於頭部110內，使得旋鈕200沿一方向之旋轉使螺柱100沿一方向旋轉且旋鈕200沿一相反方向之旋轉使螺柱100沿一相反方向旋轉。如圖2中所繪示，頭部110之突出部114可由旋鈕200之一對應凹口210及旋鈕200之近端凸緣212及一內部凸緣214固定地緊固。一般而言，頭部110可藉由任何適合緊固方法而緊固於旋鈕200之孔204內。替代地，旋鈕200可為螺柱100之一整合延伸部，例如，螺柱100之頭部110可經構形以包含旋鈕200之結構及/或旋鈕200之功能，諸如，經構形以由一使用者抓持。例如，在一實施例中，可期望使螺柱100經構形以整體包含旋鈕200，其中桿身相對於旋鈕部分固定地緊固。旋鈕200可具有安置於旋鈕200之孔204內之一套圈300或其部分。繫留緊固件10亦包含一套圈300，其界定自套圈300之一近端308沿套圈300之一縱軸線302延伸至套圈300之一遠端306的一通道304。螺柱100或其部分安置於套圈300之通道304內且可沿螺柱100之縱軸線102相對於套圈300移動。套圈300具有一近端部分320及一遠端部分310。套圈300之遠端部分310及/或遠端306可包含一面板附接構件。例如，遠端部分310及/或遠端306可經構形以藉由機械方法(諸如自咬接、箝夾、焊接、螺合、楔入或其類似者)及/或非機械方法(諸如，藉由施加黏著劑或其類似者)而附接至一面板。套圈300之近端部分320包含一向內凸緣322。近端部分320之向內凸緣322可與套圈300之近端308間隔開。向內凸緣322朝向螺柱100之縱軸線102延伸。根據一實施例，向內凸緣322延伸而接觸桿身120或其部分，諸如桿身120之近端部分122。套圈300之近端部分320之向內凸緣322經定位以在螺柱100沿縱軸線102相對於套圈300位移之後直接嚙合(例如，藉由接觸)或間接嚙合(例如，藉由間接接觸，諸如，藉由壓縮彈簧330直至彈簧330上之負載等於或超過位移力)止動環400。如圖2中所繪示，近端部分320之向內凸緣322藉由壓縮彈簧330直至彈簧330上之負載等於或超過位移力或直至向內凸緣322或止動環400無法承受此位移力而間接嚙合止動環400。據此，由凸緣嚙合止動環400係一間接嚙合，此係因為彈簧防止直接接觸。替代地，亦可考量直接嚙合，諸如，藉由消除彈簧或使止動環400及/或凸緣322經重新構形以容許直接接觸。近端部分320之向內凸緣322與止動環400之間之嚙合可將螺柱100或其部分(諸如桿身120)緊固於套圈300之通道304內。例如，當套圈300附接至面板12及/或14時，可在某段距離之後阻止螺柱100沿螺柱100之縱軸線102位移，此時止動環400嚙合套圈300之向內凸緣322。在一實施例中，在螺柱100位移某段距離之後阻止螺柱100沿螺柱100之縱軸線102位移，藉此彈簧330上之負載等於位移力，使得套圈300之向內凸緣322間接嚙合止動環400。套圈300之向內凸緣322亦可經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102的不對準。例如，套圈300之向內凸緣322可延伸至桿身120，藉此限制螺柱100之桿身120沿橫向於套圈300之縱軸線302的一方向位移。根據一實施例，當繫留緊固件10處於其縮回狀態中時，向內凸緣322經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102在桿身120之一近端部分122處的不對準。縮回狀態包含套圈縮回至旋鈕之孔中時之旋鈕相對於套圈之位置。根據另一實施例，當繫留緊固件10處於其延伸狀態中時，向內凸緣322經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102在桿身120之一遠端部分126處的不對準。延伸狀態包含套圈自旋鈕之孔延伸時之旋鈕相對於套圈之位置。在另一實施例中，向內凸緣322經構形以使套圈300之縱軸線302與螺柱100之縱軸線102同軸對準。套圈300之近端部分320及/或向內凸緣322可經構形以界定使自螺柱100之桿身120延伸之一或多個突出部或凸塊能夠穿過其之一狹槽。例如，在一實施例中，為使自桿身120延伸之突出部或凸塊在套圈300之向內凸緣322處移動通過通道304，使自桿身120延伸之突出部或凸塊與由近端部分320及/或向內凸緣322界定之狹槽對準。根據另一實施例，使螺柱100旋轉使得自桿身120延伸之突出部或凸塊與近端部分320之狹槽不對準藉由阻止螺柱100相對於套圈300位移以阻止繫留緊固件10移動至一縮回位置中而使繫留緊固件10維持於一延伸位置中。一彈簧330較佳安置於套圈300之通道304內。彈簧330延伸於套圈300之近端部分320之向內凸緣322與止動環400之間。彈簧330可為一壓縮彈簧且可抵抗套圈300之向內凸緣322及止動環400。例如，彈簧330可經構形以推動繫留緊固件10進入一縮回狀態，使得當套圈300附接至一物件時，推動螺柱100朝向一或多個物件。儘管在圖2及圖3中彈簧330係一壓縮彈簧，但在本創作之其他實施例中彈簧330可為除一壓縮彈簧之外之一彈簧。例如，一拉伸彈簧可用於繫留緊固件10中以在套圈300附接至一或多個面板時藉由推動螺柱100遠離一或多個物件而推動繫留緊固件10進入一延伸狀態。止動環400可經構形以減少套圈300之縱軸線302與螺柱100之縱軸線102的不對準。當繫留緊固件10處於一縮回狀態中時，止動環400可減少套圈300之縱軸線302與螺柱100之縱軸線102在套圈300之遠端部分310處的不對準。當繫留緊固件10處於一延伸狀態中時，止動環400可減少套圈300之縱軸線302與螺柱100之縱軸線102在套圈300之近端部分320處的不對準。在一實施例中，止動環400經構形以使套圈300之縱軸線302與螺柱100之縱軸線102同軸對準。根據另一實施例，由止動環400限制螺柱100之桿身120沿橫向於套圈300之縱軸線302的一方向位移。參考圖5至圖7，圖中繪示具有使一螺柱100'沿一方向旋轉之一旋鈕200'的一繫留緊固件20。僅為了方便讀者，使用類似於用於描述繫留緊固件10之參考元件符號的參考元件符號來描述繫留緊固件20之特徵。應瞭解，繫留緊固件10及20係非限制例示性實施例，因此，本創作之申請專利範圍不受本文所討論之圖式說明或各自參考元件符號約束。一般而言，繫留緊固件20包含一具有一緊固件部分140'之螺柱100'、一旋鈕200'、一套圈300'及一止動環400'。另外，繫留緊固件20經構形使得旋鈕200'沿一方向之旋轉經構形以使螺柱100'圍繞螺柱100'之縱軸線102'旋轉且旋鈕200'沿一相反方向之旋轉經構形以使螺柱100'無法圍繞螺柱100'之縱軸線102'沿相反方向旋轉。參考圖6至圖8，繫留緊固件20之螺柱100'具有一縱軸線102'，一遠端104'沿此縱軸線102'與一近端106'間隔開。螺柱100'亦包含一頭部110'及自頭部110'延伸之一桿身120'。止動環400'附裝至螺柱100'之桿身120'。繫留緊固件20亦具有一旋鈕200'，其可具有與螺柱100'之縱軸線102'對準之一縱軸線。旋鈕200'界定自旋鈕200'之一遠端206'延伸至旋鈕200'之一近端208'的一孔204'。螺柱100'之頭部110'至少部分安置於由旋鈕200'界定之孔204'內。較佳地，螺柱100'安置於孔204'內，使得螺柱100'之螺絲起子118'被曝露及/或可由一工具接達。旋鈕200'可具有一或多個凸緣，諸如近端凸緣212'及遠端凸緣216'。如圖6中所繪示，頭部110'之突出部114'可由旋鈕200'之一或多個凸緣緊固，使得螺柱100'可移動地固定且因此不可沿螺柱100'之縱軸線102'相對於旋鈕200'位移，但可圍繞螺柱100'之縱軸線102'相對於旋鈕200'旋轉。繫留緊固件20亦包含安置於旋鈕200'之孔204'中之一棘輪構件500'。棘輪構件500'可包含一或多個棘輪齒510'及至少一棘爪520'。儘管在圖9所繪示之實施例中一或多個棘輪齒510'安置於一棘輪512'上，但一或多個棘輪齒510'可安置於螺柱100'或旋鈕200'之一者上及/或耦合至螺柱100'或旋鈕200'之一者。例如，在一實施例中，一或多個棘輪齒510'係螺柱100'或旋鈕200'之一整合延伸部。棘爪520'可經構形為一C形彈簧522'或其部分。根據圖10中所繪示之實施例，C形彈簧522'具有(例如)藉由緊固於凹口115'

Although the present invention has been illustrated and described herein with reference to the specific embodiments, the present invention is not intended to be limited to the details shown. In particular, various modifications may be made without departing from the scope of the invention. Tethered fasteners can be used in various fields dedicated to coupling two or more objects. As an example, a mooring fastener is typically used to couple a cover to a surface and/or a panel and frame. Although embodiments of the present disclosure are discussed herein with respect to coupling or fastening a panel to a frame, those skilled in the art will appreciate that the mooring fastener can be advantageously used to couple or secure other items or features. together. A mooring fastener according to the present aspect can be coupled or attached to one or more items such that loosening the tethered fastener relative to one of the items does not detach from all of the items. firmware. Referring generally to the drawings, a mooring fastener 10 generally includes a stud 100 that includes a head 110 and extends from a head 110 along a longitudinal axis 102 of the stud 100 to a distal end 104 of the stud 100. A shaft of 120. The shaft 120 has a fastener portion 140. A snap ring 400 is attached to the shaft 120 of the stud 100 and spaced apart from the distal end 104 of the stud 100. A knob 200 defines a bore 204, and the head 110 of the stud 100 is at least partially disposed within a bore defined by the knob 200. A set of rings 300 defines a passage 304 extending from one of the proximal ends 320 of one of the ferrules 300 along one longitudinal axis 302 of the ferrule 300 to a distal end 306 of the ferrule 300, and the stud 100 is disposed in the passage 304 of the ferrule 300 Internally, it is movable relative to the ferrule 300 along the longitudinal axis 102 of the stud 100. One of the proximal portions 320 of the ferrule 300 has an inwardly directed flange 322 that extends toward the longitudinal axis 102 of the stud 100. The inward flange 322 of the proximal portion 320 of the ferrule 300 is positioned to engage the stop ring 400 after the stud 100 is displaced relative to the ferrule 300. The inward flange 322 of the ferrule 300 is configured to reduce misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100 at a proximal end portion 122 of the shaft 120 of the stud 100. The stop ring 400 is configured to reduce misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100 at a distal end portion 126 of the shaft 120 of the stud 100. Referring to Figure 1, a mooring fastener 10 for attachment to a panel in accordance with an embodiment of the present invention is provided. In general, the mooring fastener 10 includes a stud 100, a knob 200, a set of rings 300, and a stop ring 400. The stud 100 has a longitudinal axis 102 along which a distal end 104 is spaced from a proximal end 106. The stud 100 also includes a head 110 and a shaft 120 extending from the head 110. The head 110 has a cross-sectional area 112 that defines a geometric shape, such as a circle, square, triangle, hexagon, octagon, or other geometric shape. Although the cross-sectional area 112 defines a circle at various points along the longitudinal axis 102 (as depicted in FIG. 2), the cross-sectional area 112 may also define a non-geometric shape along the longitudinal axis 102. For example, the head 110 can be configured to have a non-geometric shape and thus can also have a non-geometric cross-sectional area. Additionally or alternatively, the cross-sectional area 112 may vary along the longitudinal axis 102 of the stud 100. For example, the head 110 can include a projection 114 having a cross-sectional area 116 that includes at least one dimension different from the cross-sectional area 112 of the head 110. Likewise, the head 110 can include a recess or a recess having a cross-sectional area having at least one dimension different from the cross-sectional area 112 of the head 110. As will be discussed further below, the head 110 can be configured to have a protrusion 114 and/or a notch that is secured by one or more corresponding protrusions, notches, and/or flanges of the knob 200. Referring to FIG. 2, the head 110 defines a screwdriver 118 at the proximal end 106 of the stud 100. However, according to an embodiment, the head 110 of the stud 100 does not define a screwdriver 118. The screwdriver 118 can be configured to facilitate the engagement of a head 110 of the stud 100 with a tool and/or a projection that can rotate the stud 100 by rotating the tool. For example, the screwdriver 118 can extend inwardly from the proximal end 106 of the stud 100 to define a cavity or extend outwardly from the proximal end 106 of the stud 100 to define a protrusion. The screwdriver 118 can be configured to engage a tool having, for example, a Philips tip, a Frearson tip, a Torx tip, a lip tip, an inline tip, or another type tool. The stud 100 includes a shaft 120 that extends from the head 110 along the longitudinal axis 102 of the stud 100 to the distal end 104 of the stud 100. Although the shaft 120 has a generally cylindrical shape in the embodiment illustrated in FIG. 3, the shaft 120 can have other geometric shapes (eg, rectangular, triangular, or other geometric shapes) or non-geometric shapes (including One or more straight portions and/or round portions). The shaft 120 includes a proximal portion 122 and a distal portion 126, wherein the distal portion 126 is further spaced from the head 110 than the proximal portion 122. The shaft 120 also includes a fastener portion 140 that is configured to enable the stud 100 to be secured to one or more items, such as panels 12 and 14. The fastener portion 140 can include a thread having a small diameter 144 and a large diameter 147. Additionally or alternatively, the fastener portion 140 can include one or more grooves and/or protrusions configured to engage one or more articles (eg, panels 12 and 14). According to an embodiment, the fastener portion 140 has at least one vertically extending groove and another groove extending therefrom at an angle such that the mooring fastener 10 is configured to rotate a quarter turn after the stud 100 is rotated Fastened to one or more items (eg, panel 14). Although the fastener portion 140 is spaced apart from the distal end 104 of the stud 100 in FIGS. 2 through 4B, the fastener portion 140 can extend to the distal end 104. Additionally, the fastener portion 140 can extend to the head 110. For example, in one embodiment, the fastener portion 140 extends from the distal end 104 of the stud 100 along the shaft 120 to the head 110. The distal end portion 126 of the shaft 120 can be spaced apart from or extend to the distal end 104 of the stud 100. Additionally and/or alternatively, the fastener portion 140 can be disposed on the distal portion 126 of the shaft 120. The distal portion 126 has a cross-sectional area 128 that can be different than the cross-sectional area 124 of the proximal portion 122 of the shaft 120. For example, the distal portion 126 can have a cross-sectional area 128 that is smaller than the cross-sectional area 124 of the proximal portion 122 of the shaft 120 or its diameter, or a diameter thereof. In one embodiment, the cross-sectional area 128 of the distal portion 126 or its diameter is less than the cross-sectional area 124 of the proximal portion 122 along the fastener portion 140 or its diameter and is equal to or approximately equal to the proximal portion 122 along the proximal end. The cross-sectional area 124 of the section of the shaft 120 between the portion 122 and the fastener portion 140. According to another embodiment in which the fastener portion 140 includes threads, the cross-sectional area 128 of the distal portion 126 can be equal to or less than one of the threads 144 of the fastener portion 140. The distal portion can also define a shoulder portion 130 that is adapted to receive a stop ring (e.g., stop ring 400). For example, in one embodiment, the shoulder portion 130 includes a roll or other surface feature that is adapted for attachment to one of the stop rings. The cross-sectional area 132 of the shoulder portion 130 can be different than the cross-sectional area 128 of the distal portion 126. For example, the cross-sectional area 132 of the shoulder portion 130 can be less than one of the cross-sectional areas 128 of the distal portion 126 interposed between the shoulder portion 130 and the proximal portion 122 such that a stop ring is prevented along the rod The body 120 slides over the shoulder portion 130 toward the head 110. The shaft 120 can also have a guide portion 150 that is interposed between the distal end 104 of the stud 100 and the distal end 148 of the fastener portion 140. The guide portion 150 can be configured to facilitate alignment of the fastener portion 140 with one or more items, such as one of the mating panels. If the fastener portion 140 includes threads, the guide portion 150 can have a cross-sectional area 152 that is equal to or less than the cross-sectional area 146 of the fastener portion 140 and/or one of the small diameters 144 of the threads. Additionally or alternatively, the cross-sectional area 152 of the guide portion 150 or its diameter may be less than or equal to the cross-sectional area 128 of the distal portion 126, the cross-sectional area 124 of the proximal portion 122, and/or any diameter thereof. The tether fastener 10 also includes a snap ring 400 attached to the shaft 120 of the stud 100 and spaced apart from the distal end 104 of the stud 100. For example, the stop ring 400 can be attached to the shaft 120 along the distal end portion 126 and/or the shoulder portion 130. The snap ring 400 can be attached to the mechanical ring (such as press fit, jaw clamping, welding, screwing, wedging, or the like) or non-mechanical methods (such as by applying an adhesive or the like) to The shaft 120. According to an embodiment, movement of the stop ring 400 relative to the shaft 120 of the stud 100 is eliminated or inhibited by arranging one of the studs along the shoulder portion 130. In another embodiment, the stop ring 400 is one of the shafts 120 of the stud 100 that incorporates an extension. The stop ring 400 can extend toward the ferrule 300. In an embodiment, the stop ring 400 can be configured to contact the ferrule 300 as appropriate. The tether fastener 10 further includes a knob 200 that can have a longitudinal axis aligned with the longitudinal axis 102 of the stud 100. Knob 200 defines a bore 204. The head 110 of the stud 100 is at least partially disposed within the aperture 204 defined by the knob 200. In one embodiment, the aperture 204 of the knob 200 extends from a distal end 206 of the knob 200 to a proximal end 208 of the knob 200. In another embodiment, the aperture 204 of the knob 200 extends from the distal end 206 of the knob 200 to a portion of the knob 200 that is interposed between the distal end 206 and the proximal end 208 such that the proximal end 106 of the stud 100 is surrounded by the knob 200. seal. The head 110 of the stud 100 can be secured within the aperture 204 of the knob 200 such that the head 110 can move and/or rotate within the aperture 204. However, in an embodiment, the head 110 is fixedly secured within the head 110 such that the head 110 is fixed relative to the knob 200. For example, the head 110 can be fixedly secured within the head 110 such that rotation of the knob 200 in one direction causes the stud 100 to rotate in one direction and rotation of the knob 200 in an opposite direction causes the stud 100 to rotate in an opposite direction. . As shown in FIG. 2, the protrusion 114 of the head 110 can be fixedly fastened by one of the knobs 200 corresponding to the notch 210 and the proximal flange 212 of the knob 200 and an inner flange 214. In general, the head 110 can be secured within the aperture 204 of the knob 200 by any suitable fastening method. Alternatively, the knob 200 can be an integrated extension of one of the studs 100, for example, the head 110 of the stud 100 can be configured to include the structure of the knob 200 and/or the function of the knob 200, such as by configuration A user grasps. For example, in an embodiment, it may be desirable to configure the stud 100 to integrally include the knob 200, wherein the shaft is fixedly secured relative to the knob portion. Knob 200 can have a set of rings 300 or portions thereof disposed within apertures 204 of knob 200. The tether fastener 10 also includes a set of loops 300 that define a channel 304 extending from a proximal end 308 of one of the ferrules 300 along one longitudinal axis 302 of the ferrule 300 to a distal end 306 of one of the ferrules 300. The stud 100 or portion thereof is disposed within the passage 304 of the ferrule 300 and is movable relative to the ferrule 300 along the longitudinal axis 102 of the stud 100. The ferrule 300 has a proximal end portion 320 and a distal end portion 310. The distal portion 310 and/or the distal end 306 of the ferrule 300 can include a panel attachment member. For example, distal portion 310 and/or distal end 306 can be configured to be mechanically (such as self-biting, clamping, welding, screwing, wedging, or the like) and/or non-mechanical methods (such as Attached to a panel by applying an adhesive or the like. The proximal portion 320 of the ferrule 300 includes an inward flange 322. The inward flange 322 of the proximal portion 320 can be spaced apart from the proximal end 308 of the ferrule 300. The inward flange 322 extends toward the longitudinal axis 102 of the stud 100. According to an embodiment, the inward flange 322 extends to contact the shaft 120 or a portion thereof, such as the proximal portion 122 of the shaft 120. The inward flange 322 of the proximal portion 320 of the ferrule 300 is positioned to directly engage (eg, by contact) or indirectly engage the stud 100 after being displaced relative to the ferrule 300 along the longitudinal axis 102 (eg, by indirect The contact ring 400 is contacted, such as by compressing the spring 330 until the load on the spring 330 equals or exceeds the displacement force. As illustrated in FIG. 2, the inward flange 322 of the proximal portion 320 is compressed by the compression spring 330 until the load on the spring 330 equals or exceeds the displacement force or until the inward flange 322 or the stop ring 400 cannot withstand the displacement. The force indirectly engages the stop ring 400. Accordingly, the flange engagement stop ring 400 is indirectly engaged by the spring because the spring prevents direct contact. Alternatively, direct engagement may also be considered, such as by eliminating the spring or reconfiguring the stop ring 400 and/or the flange 322 to permit direct contact. Engagement between the inward flange 322 of the proximal portion 320 and the stop ring 400 can secure the stud 100 or portion thereof (such as the shaft 120) within the passage 304 of the ferrule 300. For example, when the ferrule 300 is attached to the panels 12 and/or 14, the stud 100 can be prevented from being displaced along the longitudinal axis 102 of the stud 100 after a certain distance, at which time the stop ring 400 engages the inward of the ferrule 300. Flange 322. In one embodiment, the stud 100 is prevented from being displaced along the longitudinal axis 102 of the stud 100 after the stud 100 has displaced a certain distance, whereby the load on the spring 330 is equal to the displacement force such that the inward flange 322 of the ferrule 300 The stop ring 400 is indirectly engaged. The inward flange 322 of the ferrule 300 can also be configured to reduce misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100. For example, the inward flange 322 of the ferrule 300 can extend to the shaft 120, thereby limiting the displacement of the shaft 120 of the stud 100 in a direction transverse to the longitudinal axis 302 of the ferrule 300. According to an embodiment, the inward flange 322 is configured to reduce the longitudinal axis 302 of the ferrule 300 and the longitudinal axis 102 of the stud 100 in one of the shafts 120 when the mooring fastener 10 is in its retracted state. Misalignment at the proximal portion 122. The retracted state includes the position of the knob relative to the ferrule when the ferrule is retracted into the hole of the knob. According to another embodiment, the inward flange 322 is configured to reduce the longitudinal axis 302 of the ferrule 300 and the longitudinal axis 102 of the stud 100 in one of the shafts 120 when the mooring fastener 10 is in its extended state. Misalignment at the distal portion 126. The extended state includes the position of the knob relative to the ferrule when the ferrule extends from the hole of the knob. In another embodiment, the inward flange 322 is configured to coaxially align the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100. The proximal portion 320 and/or the inward flange 322 of the ferrule 300 can be configured to define one or more projections or projections extending from the shaft 120 of the stud 100 through one of the slots . For example, in one embodiment, the protrusions or bumps extending from the shaft 120 are caused by the projections or projections extending from the shaft 120 moving through the passages 304 at the inward flanges 322 of the ferrule 300. The slots defined by the proximal portion 320 and/or the inward flange 322 are aligned. According to another embodiment, the stud 100 is rotated such that the projection or projection extending from the shaft 120 is misaligned with the slot of the proximal portion 320 by preventing displacement of the stud 100 relative to the ferrule 300 to prevent tensioning. The firmware 10 is moved into a retracted position to maintain the tether fastener 10 in an extended position. A spring 330 is preferably disposed within the passage 304 of the ferrule 300. The spring 330 extends between the inward flange 322 and the stop ring 400 of the proximal end portion 320 of the ferrule 300. The spring 330 can be a compression spring and can resist the inward flange 322 and the stop ring 400 of the ferrule 300. For example, the spring 330 can be configured to urge the tether fastener 10 into a retracted state such that when the ferrule 300 is attached to an article, the stud 100 is urged toward one or more items. Although the spring 330 is a compression spring in Figures 2 and 3, in other embodiments of the present disclosure the spring 330 can be a spring other than a compression spring. For example, a tension spring can be used in the tether fastener 10 to urge the tether fastener 10 into an extension by pushing the stud 100 away from the one or more items when the ferrule 300 is attached to the one or more panels. status. The stop ring 400 can be configured to reduce misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100. The stop ring 400 reduces misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100 at the distal end portion 310 of the ferrule 300 when the tether fastener 10 is in a retracted state. The stop ring 400 reduces misalignment of the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100 at the proximal end portion 320 of the ferrule 300 when the tether fastener 10 is in an extended condition. In an embodiment, the stop ring 400 is configured to coaxially align the longitudinal axis 302 of the ferrule 300 with the longitudinal axis 102 of the stud 100. According to another embodiment, the shaft 120 of the stud 100 is constrained by the stop ring 400 in a direction transverse to the longitudinal axis 302 of the ferrule 300. Referring to Figures 5 through 7, a mooring fastener 20 having a knob 200' that rotates a stud 100' in one direction is illustrated. For convenience of the reader, the features of the mooring fastener 20 are described using reference element symbols similar to those used to describe the tether fastener 10. It is to be understood that the tethered fasteners 10 and 20 are non-limiting exemplary embodiments and, therefore, the scope of the present invention is not limited by the description of the drawings or the respective referenced component symbols. In general, the mooring fastener 20 includes a stud 100' having a fastener portion 140', a knob 200', a set of rings 300', and a stop ring 400'. Additionally, the mooring fastener 20 is configured such that rotation of the knob 200' in one direction is configured to rotate the stud 100' about the longitudinal axis 102' of the stud 100' and the knob 200' rotates in an opposite direction The configuration is such that the stud 100' cannot rotate in the opposite direction about the longitudinal axis 102' of the stud 100'. Referring to Figures 6-8, the stud 100' of the mooring fastener 20 has a longitudinal axis 102' along which a distal end 104' is spaced from a proximal end 106'. The stud 100' also includes a head 110' and a shaft 120' extending from the head 110'. The snap ring 400' is attached to the shaft 120' of the stud 100'. The tether fastener 20 also has a knob 200' that can have a longitudinal axis aligned with the longitudinal axis 102' of the stud 100'. Knob 200' defines a hole 204' that extends from one distal end 206' of knob 200' to a proximal end 208' of one of knobs 200'. The head 110' of the stud 100' is at least partially disposed within the aperture 204' defined by the knob 200'. Preferably, the stud 100' is disposed within the aperture 204' such that the screwdriver 118' of the stud 100' is exposed and/or accessible by a tool. The knob 200' can have one or more flanges, such as a proximal flange 212' and a distal flange 216'. As illustrated in Figure 6, the projection 114' of the head 110' can be secured by one or more of the knobs 200' such that the stud 100' is movably secured and therefore not slid along the stud 100' The axis 102' is displaced relative to the knob 200', but is rotatable relative to the knob 200' about the longitudinal axis 102' of the stud 100'. The tether fastener 20 also includes a ratchet member 500' disposed in the aperture 204' of the knob 200'. The ratchet member 500' can include one or more ratchet teeth 510' and at least one pawl 520'. Although one or more ratchet teeth 510' are disposed on a ratchet 512' in the embodiment illustrated in FIG. 9, one or more ratchet teeth 510' may be disposed on one of the studs 100' or knobs 200' Up and/or coupled to one of the studs 100' or knobs 200'. For example, in one embodiment, one or more ratchet teeth 510' are one of the studs 100' or knobs 200' that incorporate an extension. The pawl 520' can be configured as a C-shaped spring 522' or a portion thereof. According to the embodiment illustrated in Figure 10, the C-shaped spring 522' has, for example, by being fastened in a recess 115' (which is defined in the projection 114' of the head 110' of the stud 100') And coupled to one of the studs 100', the screwdriver 524'. Additionally or alternatively, the pawl 520' can be disposed on the other of the stud 100' or knob 200' and/or coupled to the other of the stud 100' or knob 200'. According to an embodiment, the pawl 520' is one of the stud 100' or the knob 200' that integrates the extension. One or more ratchet teeth 510' can be engaged directly or indirectly with the pawl 520'. The pawl 520' can be configured to engage one or more ratchet teeth 510', for example, after the knob 200' is rotated in one direction and after the knob 200' is rotated in the opposite direction 510' allows the stud 100' to rotate in a direction about the longitudinal axis 102'. Accordingly, in one embodiment, rotation of the knob 200' in one direction causes the stud 100' to rotate due to engagement between the ratchet teeth 510' and the pawl 520', and rotation of the knob 200' in the opposite direction does not cause The stud 100' rotates. In another embodiment in which the stud 100' includes a screwdriver 118', the stud 100' can be rotated in one direction by rotating the knob 200' and/or rotating the screwdriver 118', and can only borrow The stud 100' is rotated in the opposite direction by rotating the screwdriver 118'. According to yet another embodiment, the mooring fastener 20 is configured to be hand tightened, but once tightened by hand, a tool is required to release. Additional examples of ratchet members that may be suitably utilized in the tether fastener 20 are described in U.S. Patent No. 5,642,972, the disclosure of which is incorporated herein in Referring to Figures 11A-12, the mooring fastener 20 further includes a set of loops 300' that define a proximal end 308' from one of the ferrules 300' extending along one longitudinal axis 302' of the ferrule 300' to the ferrule 300' One of the channels 306' of the distal end 306'. The stud 100' or portion thereof is disposed within the passage 304' of the ferrule 300' and is movable relative to the ferrule 300' along the longitudinal axis 102' of the stud 100'. The distal portion 310' and/or the distal end 306' of the ferrule 300' can have a panel attachment member. The ferrule 300' has a proximal end portion 320' that includes an inward flange 322' and an outward flange 324'. The inward flange 322' and/or the outward flange 324' can be spaced apart from the proximal end 308' of the ferrule 300'. The inward flange 322' extends toward the longitudinal axis 102' of the stud 100'. The inward flange 322' of the proximal portion 320' of the ferrule 300' is positioned to directly engage (eg, by contact) or indirectly after the stud 100' is displaced relative to the ferrule 300' along the longitudinal axis 102'. (For example, by indirect contact, such as by compressing the spring 330' until the load on the spring 330' equals or exceeds the displacement force) the snap ring 400'. Engagement between the inward flange 322' of the proximal portion 320' and the stop ring 400' can secure the stud 100' or portion thereof (such as the shaft 120') within the channel 304' of the ferrule 300' . For example, when the ferrule 300' is attached to the panel 12' and/or 14', the stud 100' can be prevented from axially displaced after a certain distance, at which point the stop ring 400' engages the inward of the ferrule 300' Flange 322'. The inward flange 322' and the outward flange 324' of the ferrule 300' can also be configured to reduce misalignment of the longitudinal axis 302' of the ferrule 300' with the longitudinal axis 102' of the stud 100'. For example, the inward flange 322' and the outward flange 324' of the ferrule 300' can extend to the shaft 120' and the knob 200', respectively, thereby restricting the shaft 120' of the stud 100' from traversing the ferrule The longitudinal axis 302' of 300' is displaced in one direction. According to an embodiment, the inward flange 322' and the outward flange 324' are configured to reduce the longitudinal axis 302' of the ferrule 300' and the stud 100 when the mooring fastener 20 is in its retracted state The misalignment of the longitudinal axis 102' at the proximal end portion 122' of one of the shafts 120'. The outward flange 324' of the ferrule 300' extends outwardly toward the knob 200'. The outward flange 324' can be positioned to engage an inwardly extending flange (eg, the distal flange 216') of one of the knobs 200' after the stud 100' is displaced relative to the ferrule 300'. After the stud 100' is displaced relative to the ferrule 300', the stud 100' or portion thereof can be secured to the ferrule by engaging the outward flange 324' with the proximal flange 216' of the knob 200'. Within 300'. According to an embodiment, when the inward flange 322' of the proximal portion 320' engages the stop ring 400', the outward flange 324' can engage the proximal flange 216' of the knob 200'. In another embodiment, when the engagement between the inward flange 322' of the ferrule 300' and the stop ring 400' does not prevent the stud 100' from being displaced relative to the ferrule 300', the ferrule 300' is oriented Engagement occurs between the outer flange 324' and the proximal flange 216' of the knob 200'. In yet another embodiment, when the engagement between the outward flange 324' of the ferrule 300' and the proximal flange 216' of the knob 200' does not prevent the stud 100' from being displaced relative to the ferrule 300', the sleeve Engagement occurs between the inward flange 322' of the ring 300' and the stop ring 400'.
