在此情形時，鉸鏈台座2係在固定框61之一方侧部 的預定位置將台座的突出部22設置在門7的側面侧，並透 過墊片29將安裝螺絲28螺裝在固定部21的螺絲孔210， 以固定在固定框61的側部。藉此，鉸鏈台座2的銷插通部 23係沿著固定框61的一方側部朝上下方向配置。 而鉸鏈葉3係如第4圖所示，將設在葉本體31的一 對卡止爪33、33於門7的缺口 70之缺口始端的上下兩侧 卡止於門的侧面自由緣，然後將定位固定部34的各塊，亦 ❹即將端部塊341及一對側部塊342、342以從門外侧朝缺口 70内稍微按壓的方式予以嵌入，而將葉本體31被著在缺 口 7〇上’亦即被著在缺口 70的緣部周邊7〇1、7〇2、7〇2。 此時一對檔止件35、35係被按壓在缺口 70的緣部，且傾 斜於凹部36、36,而與各侧部塊342、342 —起被壓入門7 的内面側。藉由將該鉸鏈葉3組裝於缺口 70，定位固定部 34的各塊341、342、342係沿著缺口 70的緣部被完全嵌 入’當葉本體31的内面緣部311所形成的平面完全抵接於 缺口 7〇的緣部周邊701、702時，鉸鏈葉3整體係被定位 13 321799 201033448 固疋在缺口 70上。與此同時，和側部塊342、342 一起被 壓入缺口 7G内之槽止件35、35係於被解除來自缺口 70 緣部的按壓時，藉其彈性復原而從各侧部塊M2、⑷的上 下面相對於缺口 7〇的緣部向外侧突出，並壓接在門7的内 ,面藉由該等槽止件35、35的楔合作用，鉸鏈葉3被防止 從缺70脫落，而完全被安襄固定。藉此，銷插通部％ 係在門7的内側沿著—方侧部朝上下方向配置。 ^以如此方式將鉸鏈台座2安裝在箱體6，並將鉸鏈葉 3安裝在門7的話，將門7對位於箱體6正面的固定框61， 並於鉸鏈葉3的一對銷插通部32、32之間以可連通的方式 配置鉸鏈台座2之銷插通部23，即可組合鉸鏈葉3與鉸鏈 台座2。然後，從上方將鉸鏈銷4插入該等銷插通部23、 32 ’而連結箱體侧的鉸鏈台座2與門侧的鉸鏈葉3。藉此， Η 7即能以開閉方式結合在箱體6。門7的開閉狀態請參 照第7圖及第8圖。第7圖顯示門7的關閉狀態，第8圖 顯示門7的打開狀態。 如以上說明，在該鉸鏈裝置1中，如上所述尤其由葉 本體31、銷插通部32、一對卡止爪33、33、定位固定部 34及檔止件35、35構成門側的鉸鏈葉3。而於將該鉸鏈葉 3安裝在門7時，一對卡止爪33、33卡止在設置在門7的 缺口 70之切入始端的上下兩侧，並將定位固定部34嵌入 缺口 70内，並將葉本體31被著在缺口 70上，藉此使檔止 件35、35壓接於門7的内面，因此即能以簡便方式將鉸鏈 葉3簡易地裝設在門7。因此’依據該鉸鏈裝置1即可不 14 321799 201033448 必使用安裝螺絲而簡便地進行門側的鉸鏈葉3的安裝。如 此可使鉸鏈裝置1整體的安裝作業變為容易，並可減少鉸 鏈裝置1整體的安裝螺絲零件數量，而謀求成本的降低。 再者，該鉸鏈裝置1復具有如下所述優點： (1) 鉸鏈葉3係由合成樹脂材料一體形成，因此可容 易進行其製造。 (2) 鉸鏈葉3的定位固定部34係以沿著門7的角落部 7C之缺口 70的緣部之外形突狀地形成於葉本體31的内面 側，並且由可壓接於正面侧缺口部70F的終端緣部之端部 塊341、及可壓接於侧面侧缺口部70S的‘上下緣部之一對 側部塊342、342所構成。再者，在葉本體31的内面侧由 端部塊341、及一對側部塊342、342所包圍的空間係形成 可嵌合鉸鏈台座2的銷插通部23，並且，鉸鏈葉3的銷插 通部32係以可和鉸鏈台座2的銷插通部23連通的方式貫 通形成於一對側部塊342、342，因此可簡化該等各部的構 ❿造，並能進一步容易進行鉸鏈葉3的製造。 (3) 鉸鏈葉3的檔止件35、35係於定位固定部34的 上下面藉開口於葉本體31側的凹部36、36而形成可傾斜， 且各檔止件35的前端部係突出於定位固定部34的上下面 之外侧，因此能以簡易的構造形成具有楔合作用的檔止件 35、35。 (4) 箱體侧的鉸鏈台座2之本體20係形成為剖面大致 L字形，且具有平板狀的固定部21、及從該固定部21的 一端大致延伸向直角方向的突出部22,並於突出部22的 15 321799 201033448 前端部之與固定部21相反側的面，沿突出部22的前端平 行地形成有圓筒狀的銷插通部23。因此，鉸鏈台座2亦可 形成為簡易的形狀及構造。 (5) 在此情形時，因鉸鏈台座2係由金屬材料一體形 成，故可容易地進行其製造。 (6) 在此情形時，由於在本體20從圓筒狀的銷插通部 23的外周面朝突出部22的前端形成有傾斜面24，且該傾 斜面24相對於突出部22具有預定的角度，而限制鉸鏈葉 3的一方轉動端的轉動，因此可限制鉸鏈葉3的轉動，亦 © 即將門7的轉動限制在所想要的轉動範圍。而且又於突出 部22的兩侧與固定部21的兩侧之間，連續於該傾斜面24 的連結部25係形成為大致三角形，因此可強化鉸鏈台座2 的構造。 (7) 在此情形時，於本體20的突出部22在與銷插通 部23相同之側，於與銷插通部23之間隔開預定間隔突設 有剖面大致L字形形狀的遮蔽部26至與銷插通部23大致 ◎ 相同位置，因此藉該遮蔽部26可遮蔽鉸鏈台座2的突出部 22與銷插通部23之間的空間（凹部），並能謀求美觀的提 升。 (8) 在此情形時，於銷插通部23與遮蔽部26之間形 成有槽27，在該槽27收容鉸鏈葉3的另一方轉動端，而 容許該鉸鏈葉3之預定範圍的轉動，並限制超出該範圍的 轉動，因此可限制鉸鏈葉3的轉動，亦即將門7的轉動限 制在所想要的轉動範圍。 16 321799 201033448 (9)又，鉸鏈葉3係以通過葉太 31F與各侧面被著部31S、31S的“合方口1㈤正面被著部 於正面被著部31F朝各側面被著部;以向，中二：相對 延伸的虛擬線作為對稱中心線而 & 、續方向 座2係以通過本體20的固定部21與成=㈣造，而錢鏈台 ❺ 之:心’且相對於固定部21朝突出部22的連續方向^ 的虛擬線作為對稱中心線而形成對稱構造。由於上述 葉3及鉸鏈台座2可顛倒使用4因此該鉸鏈裝置土的^裝 位置並不限定在機架5的一方侧部’而可對應朝右開、朝 左開之雙方’或對應朝上開、朝下開之雙方。 再者，於上述實施形態中，雖是將鉸鏈葉3的銷插通

(3) The stoppers 35, 35 of the hinge leaf 3 are formed on the upper and lower sides of the positioning fixing portion 34 by the recesses 36, 36 opening on the side of the blade body 31, and are tiltable, and the front end portions of the respective stoppers 35 are protruded. On the outer side of the upper and lower surfaces of the positioning fixing portion 34, the stoppers 35, 35 having the wedge cooperation can be formed in a simple configuration. (4) The main body 20 of the hinge pedestal 2 on the casing side is formed in a substantially L-shaped cross section, and has a flat-shaped fixing portion 21 and a protruding portion 22 extending substantially from one end of the fixing portion 21 in a right-angle direction, and 15 321799 201033448 The surface of the front end portion opposite to the fixed portion 21 of the front end portion is formed with a cylindrical pin insertion portion 23 in parallel along the front end of the protruding portion 22. Therefore, the hinge pedestal 2 can also be formed in a simple shape and configuration. (5) In this case, since the hinge pedestal 2 is integrally formed of a metal material, its manufacture can be easily performed. (6) In this case, since the body 20 is formed with an inclined surface 24 from the outer peripheral surface of the cylindrical pin insertion portion 23 toward the front end of the protruding portion 22, and the inclined surface 24 has a predetermined shape with respect to the protruding portion 22. The angle, while restricting the rotation of one of the rotational ends of the hinge leaf 3, thus limits the rotation of the hinge leaf 3, and also limits the rotation of the door 7 to the desired range of rotation. Further, between the both sides of the protruding portion 22 and the both sides of the fixing portion 21, the connecting portion 25 continuous with the inclined surface 24 is formed in a substantially triangular shape, so that the structure of the hinge pedestal 2 can be strengthened. (7) In this case, the projection portion 22 of the main body 20 is provided with a shielding portion 26 having a substantially L-shaped cross section at a predetermined interval from the pin insertion portion 23 on the same side as the pin insertion portion 23. Since the pin insertion portion 23 is substantially at the same position as the pin insertion portion 23, the space (concave portion) between the protruding portion 22 of the hinge pedestal 2 and the pin insertion portion 23 can be shielded by the shielding portion 26, and the appearance can be improved. (8) In this case, a groove 27 is formed between the pin insertion portion 23 and the shielding portion 26, and the other rotation end of the hinge leaf 3 is accommodated in the groove 27 to allow the predetermined range of rotation of the hinge leaf 3 And limiting the rotation beyond this range, thus limiting the rotation of the hinge leaf 3, that is, limiting the rotation of the door 7 to the desired range of rotation. 16 321799 201033448 (9) Further, the hinge leaf 3 is partially passed to the front side by the front side portion 31F by the leaf side 31F and the side surface portions 31S and 31S of the side portions 31S and 31S; Xiang, Zhong 2: the relatively extended virtual line is used as the symmetrical center line, and the continuation direction 2 is made by the fixed part 21 of the body 20 and the == (4), and the money chain is: the heart 'and relative to the fixed The imaginary portion 21 forms a symmetrical structure as a symmetrical center line toward the symmetry center line of the protruding portion 22. Since the leaf 3 and the hinge pedestal 2 can be used upside down, the mounting position of the hinge device is not limited to the frame 5. The one side portion ' can correspond to both the right side opening and the left side opening or the two sides facing upwards and downwards. Further, in the above embodiment, the pin of the hinge leaf 3 is inserted into the vicinity. 32 is integrated with the clamp fixing portion 34, but the portions may be separately formed. Further, in the case of the positioning fixing portion 34, the end block 341 and the opposite side blocks 342, 342 are continuously formed. However, the parts may be separated, and moreover, although the hinges 35 of the hinge leaves 3 are The pair of side blocks 342, 342 are formed in pairs, but the stopper 35 may be provided on the end surface of the end block 341, or may be further provided on each of the end block 341 and each of the side blocks 342 342. Further, although the drum key pedestal 2 is locked to the fixing frame 61 of the casing 6 by the mounting screw 28, it is of course possible to use welding.
