三葉鉸鏈 Trefoil hinge

本創作係關於一種鉸鏈，尤指一種摩擦部分較少，可以輕快折轉的三葉鉸鏈。 This creation is about a hinge, especially a three-leaf hinge that has fewer friction parts and can be easily folded.

裝在器具或門窗上的兩個金屬構件，可相互連結折轉、開關的物品係屬習知，此物品稱為鉸鏈。習用的鉸鏈依其裝置對象的不同而有很多類型。 It is a common practice to attach two metal members mounted on an appliance or a door and window to each other to fold and switch the articles. This item is called a hinge. Custom hinges come in many types depending on the device they are used for.

以常用的蝶型鉸鏈和旗型鉸鏈而言，二者皆包含一對以樞軸相互連結折轉的鉸葉。使用時，將其中一鉸葉以螺釘鎖定於門框，另一鉸葉以螺釘鎖定於門板，從而門板即能透過鉸鏈支持於門框開關自如。至於蝶型鉸鏈和旗型鉸鏈的差異在於，前者那對鉸葉為面對面配置，後者那對鉸葉係上下配置。 In the case of conventional butterfly hinges and flag hinges, both comprise a pair of hinges pivotally coupled to each other. In use, one of the hinges is screwed to the door frame, and the other hinge is locked to the door panel by screws, so that the door panel can be supported by the door frame through the hinge. The difference between the butterfly hinge and the flag hinge is that the pair of hinges of the former are face-to-face and the latter are arranged up and down.

此外，還有一種三葉鉸鏈。如第1圖所示，該三葉鉸鏈60包括二鎖定於門框的門框鉸葉61、一鎖定於門板的門板鉸葉62，及一將門板鉸葉62組裝於二門框鉸葉61之間的樞軸63，使三鉸葉可相互連結折轉。所述門框鉸葉61和門板鉸葉62之間並以一間隔環64隔開，防止門框鉸葉61和門板鉸葉62直接摩擦接觸。 In addition, there is a three-leaf hinge. As shown in FIG. 1, the three-bladed hinge 60 includes two door hinges 61 locked to the door frame, a door hinge 62 locked to the door panel, and a door hinge 46 assembled between the two door hinges 61. The pivot 63 allows the three hinges to be folded together. The door frame hinges 61 and the door hinges 62 are separated by a spacer ring 64 to prevent the door frame hinges 61 and the door hinges 62 from being in direct frictional contact.

由於習用三葉鉸鏈60的樞軸63與門框鉸葉61和門板鉸葉62保持轉動配合的關係，因此樞軸63係處於可以轉動的狀態，結果，當門板做開關動作時，整支樞軸63就會隨著門 板鉸葉62的折轉而繞門框鉸葉61轉動。由於樞軸63旋轉的關係，摩擦部分相對較多，因此難以傳達輕盈的運動。 Since the pivot 63 of the conventional three-bladed hinge 60 maintains a rotationally engaged relationship with the door hinge 65 and the door hinge 62, the pivot 63 is in a rotatable state, and as a result, when the door is pivoted, the entire pivot 63 will follow the door The hinge leaf 62 is turned around and rotated about the door hinge 61. Due to the rotation of the pivot 63, the friction portion is relatively large, so that it is difficult to convey a light motion.

本創作乃為解決上述問題所成，其目的在於提供一種三葉鉸鏈，透過組裝於門框鉸葉的螺釘鎖緊樞軸，防止樞軸轉動，使鉸鏈由於減少摩擦的關係而能輕快地折轉。 The present invention has been made to solve the above problems, and an object thereof is to provide a three-blade hinge that can be pivoted by a screw that is assembled to a hinge of a door frame to prevent pivoting, so that the hinge can be easily folded due to friction reduction. .

具體實現本創作的鉸鏈，包含二門框鉸葉，每一門框鉸葉包括一葉片和一軸套，該葉片具有一組安裝孔，該軸套具有一沿軸向設置的軸孔；一門板鉸葉，包括一葉片和一軸套，該葉片具有一組安裝孔，該軸套具有一沿軸向設置的軸孔；及一樞軸，組裝於該二門框鉸葉和門板鉸葉的軸孔，將該門板鉸葉連結於該二門框鉸葉之間；其中，該門框鉸葉的軸套具有一與該軸孔垂直相交的螺孔，用以組裝一螺釘；該樞軸的上、下部各有一沿徑向凹設的軸頸，該螺釘的前端抵緊於該軸頸，藉此鎖緊該樞軸，使其保持於不能轉動的狀態。 The hinge for realizing the present invention comprises two door hinges, each of the hinges includes a blade and a sleeve, the blade has a set of mounting holes, the sleeve has an axial hole disposed axially; and a door hinge The utility model comprises a blade and a bushing, the blade has a set of mounting holes, the bushing has an axial hole arranged axially, and a pivot shaft assembled in the shaft hole of the hinged leaf of the two door frame and the hinge of the door panel, The door hinge is coupled between the hinges of the two door frames; wherein the sleeve of the hinge of the door frame has a screw hole perpendicularly intersecting the shaft hole for assembling a screw; and each of the upper and lower portions of the pivot has A journal that is recessed in the radial direction, the front end of the screw abuts against the journal, thereby locking the pivot so that it remains in a non-rotatable state.

所述樞軸的上、下端分別設有一沿軸向設置的陰螺紋部，供二端蓋分別組裝於該樞軸，該端蓋包含一陽螺紋部，及一自該陽螺紋部的一端沿徑向擴大而成的頭部，該端蓋透過該陽螺紋部旋進該陰螺紋部而結合於該樞軸；該頭部的直徑與該門框鉸葉軸套的外徑相當，以覆蓋該樞軸及軸套的端面。 The upper and lower ends of the pivot shaft are respectively provided with a female threaded portion disposed in the axial direction, wherein the two end caps are respectively assembled to the pivot shaft, the end cap comprises a male threaded portion, and one end of the male threaded portion is along the diameter To the enlarged head, the end cap is coupled to the pivot shaft through the male thread portion and screwed into the female thread portion; the diameter of the head is equivalent to the outer diameter of the door frame hinge sleeve to cover the pivot The end face of the shaft and bushing.

所述門板鉸葉又包含二間隔套分別裝組裝於該門板鉸葉軸套的上、下端，該間隔套包括一圓周部、一從該圓周部的一端沿徑向擴大而成的凸緣，及一沿軸向貫穿該圓周部和凸緣的孔洞，該圓周部套入該軸套的軸孔，該凸緣平貼於該軸套的端 面，該樞軸貫穿該孔洞。 The door hinges further comprise two spacer sleeves respectively assembled on the upper and lower ends of the door hinge sleeve, the spacer sleeve comprising a circumferential portion and a flange extending radially from one end of the circumferential portion. And a hole extending axially through the circumferential portion and the flange, the circumferential portion being sleeved into the shaft hole of the sleeve, the flange being flatly attached to the end of the sleeve The pivot extends through the aperture.

本創作對照習用鉸鏈的功效在於，由於樞軸被螺設在門框鉸葉的螺釘鎖緊而無轉動之虞，因此只有門板鉸葉會隨著門板的開關而繞其間隔套折轉，摩擦部分相對於習用三葉鉸鏈以樞軸做旋轉少許多，故能輕快地折轉。 The effect of this creation on the custom hinge is that since the pivot is screwed on the hinge of the door frame and the screw is locked without rotation, only the hinge of the door will be folded around the spacer with the switch of the door, the friction part Compared with the conventional three-leaf hinge, the pivoting is much less, so it can be folded briskly.

The three-bladed hinge 10 includes a two-door hinge leaf 20, a door hinge 30, and a pivot 40. among them:

門框鉸葉20，包含一葉片21和一軸套22，該葉片21為扁平狀，上面設有一組沈頭孔23，用來安裝一組螺絲(圖未式)，以藉該組螺絲將二門框鉸葉20上下分開鎖定於門框(圖未式)。軸套22為圓筒狀而一體形成於葉片21的一側，其具有一沿軸方向設置的軸孔24供組裝樞軸40之用，以及一沿徑向設置的螺孔25，用來組裝一螺釘26，以透過螺釘26將樞軸40同時 鎖緊於二門框鉸葉20，避免樞軸40轉動。 The door frame hinge 20 comprises a blade 21 and a sleeve 22, wherein the blade 21 is flat and has a set of countersunk holes 23 for mounting a set of screws (not shown) for the two frames by the set of screws. The hinges 20 are vertically locked to the door frame (not shown). The sleeve 22 is cylindrical and integrally formed on one side of the blade 21, and has a shaft hole 24 disposed in the axial direction for assembling the pivot 40, and a screw hole 25 disposed in the radial direction for assembly. a screw 26 to transmit the pivot 40 simultaneously through the screw 26 The two door frame hinges 20 are locked to prevent the pivot 40 from rotating.

門板鉸葉30，設置於二門框鉸葉20之間，其與門框鉸葉20的構造相當，同樣由一葉片31和一軸套32構成，該葉片31具有一組沈頭孔33，供安裝一組螺絲(圖未式)，以透過該組螺絲將門板鉸葉30鎖緊於門板(圖未式)。所述軸套32連接於葉片31的一側，並提供一組裝樞軸40需用的軸孔34。此外，門板鉸葉30還包含二間隔套35分別組裝於軸套32的上、下端，該間隔套35以耐磨耗的工程塑膠製成T形中空體，包括一圓周部36、一從圓周部36的一端沿徑向擴大而成的凸緣37，及一沿軸向貫穿圓周部36和凸緣37的孔洞38，該圓周部36套入軸孔34內，直到凸緣37平貼於軸套32的端面為止，孔洞38供樞軸40貫穿間隔套35，如此，將間隔套35固定於門板鉸葉30，使間隔套35保持在門框鉸葉20和門板鉸葉30之間，避免同為金屬材質製成的門框鉸葉20和門板鉸葉30直接摩擦接觸，而造成磨損與發出擾人的金屬摩擦聲音，同時支撐門板鉸葉30折轉。 The door hinges 30 are disposed between the two door hinges 20, which are equivalent to the structure of the door hinges 20, and are also constituted by a blade 31 and a sleeve 32 having a set of countersunk holes 33 for mounting Set the screws (not shown) to lock the door hinges 30 to the door panel through the set of screws (not shown). The sleeve 32 is coupled to one side of the blade 31 and provides a shaft bore 34 for assembly of the pivot 40. In addition, the door hinge 30 further includes two spacer sleeves 35 respectively assembled on the upper and lower ends of the sleeve 32.
