Around the shaft 5.
又，此處，如圖3之橫剖面圖所示，將一個基板2a的兩端固定轉軸5嵌入至另一基板2b的轉軸把持部6，從而使該轉軸把持部6圍繞於該兩端固定轉軸5的周圍，藉此，使兩個基板2a、2b彼此連結，並且，使轉軸把持部6可圍繞兩端固定轉軸5而相對地滑動移位，從而，使基板2a、2b能圍繞該兩端固定轉軸5而轉動移位。 Here, as shown in the cross-sectional view of FIG. 3, the both ends of the fixing plate 5 of one substrate 2a are fitted to the rotating shaft holding portion 6 of the other substrate 2b, so that the rotating shaft holding portion 6 is fixed around the both ends. The periphery of the rotating shaft 5, whereby the two substrates 2a, 2b are coupled to each other, and the rotating shaft holding portion 6 is relatively slidably displaced around the rotating shaft 5 at both ends, thereby enabling the substrates 2a, 2b to surround the two The end is fixed to the shaft 5 and is rotationally displaced.
藉此，利用一體形成於各個基板2a、2b之兩端固定轉軸5及轉軸把持部6，使基板2a、2b能轉動移位，故而，無需另外設置如先前技術般的、遍及基板的長度方向的大致全長之由金屬等製造的軸構件，因此，能減少構件個數。 Thereby, the rotating shaft 5 and the rotating shaft holding portion 6 are fixedly formed at both ends of the respective substrates 2a and 2b, so that the substrates 2a and 2b can be rotationally displaced. Therefore, it is not necessary to separately provide the longitudinal direction of the substrate as in the prior art. Since the shaft member made of metal or the like is substantially the entire length, the number of components can be reduced.
結果，可容易地組裝活頁裝訂具1，且能有效地提升進行大量生產等時的製造效率，不僅如此，亦能降低金屬製軸構件的製造中的材料成本。 As a result, the loose-leaf binder 1 can be easily assembled, and the manufacturing efficiency at the time of mass production or the like can be effectively improved, and the material cost in the manufacture of the metal shaft member can be reduced.
此處，圖示之活頁裝訂具1中，不僅於一個基板2a設有兩端固定轉軸5，又於另一基板2b亦設有兩端固定轉軸5，並且，與此對應地，於一個基板2a亦設有轉軸把持部6。 Here, in the illustrated binder assembly 1, not only the one end of the substrate 2a is provided with the rotating shaft 5, but also the other substrate 2b is provided with the rotating shaft 5 at both ends, and correspondingly, one substrate is provided. The shaft holding portion 6 is also provided in 2a.
與僅於一個基板設有兩端固定轉軸且僅於另一基板設有轉軸把持部的情況相比，此情況下，於能穩定地進行基板2a及2b之相互連結及其等的轉動移位的方面較佳。 Compared with the case where only one of the substrates is provided with the rotating shaft at both ends and the rotating shaft holding portion is provided only for the other substrate, in this case, the mutual connection of the substrates 2a and 2b and the rotational displacement thereof can be stably performed. The aspect is better.
此處，於圖示之活頁裝訂具1中，任一基板2a、2b中，均係於隔著其長度方向的中央區域的一側，設有一根以上的兩端固定轉軸5， 又，於長度方向的另一側，設有一個以上的轉軸把持部6。進而，此處，隔著長度方向的中央區域而設的該等兩端固定轉軸5與轉軸把持部6的配設根數或個數係設為彼此相等的數量(例如三根或三個)，且將一個基板2a與另一基板2b設為相同的形狀。 Here, in the sheet binder 1 shown in the drawing, any one of the substrates 2a and 2b is provided on one side of the central region in the longitudinal direction thereof, and one or more ends are fixed to the rotating shaft 5, Further, one or more rotating shaft gripping portions 6 are provided on the other side in the longitudinal direction. Further, here, the number or the number of the arrangement of the both end fixed rotating shafts 5 and the rotating shaft gripping portion 6 provided in the central portion in the longitudinal direction is set to be equal to each other (for example, three or three). Further, one substrate 2a and the other substrate 2b have the same shape.
根據此種構成，例如，可利用具有單一的模腔形狀的射出成形用模具等而成形一個基板2a與另一基板2b該等兩個基板，從而能防止製造成本增加。 According to such a configuration, for example, one substrate 2a and the other substrate 2b can be formed by using a mold for injection molding having a single cavity shape or the like, and the manufacturing cost can be prevented from increasing.
然而，本發明並不限於上文所述之兩端固定轉軸5與轉軸把持部6的配設態樣。亦即，只要於至少一個基板設有一個以上的兩端固定轉軸、且於另一基板設有對應的一個以上的轉軸把持部亦即可。 However, the present invention is not limited to the arrangement of the both ends of the fixed shaft 5 and the shaft holding portion 6 as described above. In other words, it is sufficient that at least one of the substrates is provided with one or more ends fixed to the rotating shaft, and the other substrate is provided with one or more corresponding rotating shaft holding portions.
例如，本發明中，雖省略圖示，但如上文所述，亦包括如下等態樣：於一個基板僅設有兩端固定轉軸、且於另一基板僅設有轉軸把持部；或者，於兩個基板，分別在其長度方向上交替地設有兩端固定轉軸與轉軸把持部。 For example, in the present invention, although not shown in the drawings, as described above, the following aspects are also included: only one end of the substrate is fixed to the rotating shaft, and the other substrate is only provided with the rotating shaft holding portion; or The two substrates are alternately provided with a fixed rotating shaft and a rotating shaft holding portion at both ends in the longitudinal direction thereof.
兩端固定轉軸5例如可以圖4之態樣而與基板2a一體地設置，圖4中僅表示一個基板2a。亦即，圖示之實施形態中，於基板2a的背面B，相互隔著固定的間隔而一體地形成有複數個圓柱狀等形狀的***部7，該***部7具有與基板2a的長度方向平行的軸線，又，於該等***部7之間，與該***部7同軸地配置有棒狀的兩端固定轉軸5，該兩端固定轉軸5具有直徑小於***部7的圓形剖面，並且，使兩端固定轉軸5的兩端各自一體地固定於各***部7的端面7a。當於另一基板2b設有兩端固定轉軸5時，亦如圖5所示，可在與此相同的態樣下，與基板2b一體地形成兩端固定轉軸5。 The both ends of the fixed rotating shaft 5 can be integrally provided with the substrate 2a as shown in Fig. 4, and only one substrate 2a is shown in Fig. 4. In other words, in the embodiment shown in the drawing, a plurality of ridges 7 having a cylindrical shape or the like are integrally formed on the back surface B of the substrate 2a at a fixed interval, and the ridges 7 have a length direction with respect to the substrate 2a. Further, between the raised portions 7, a rod-shaped fixed end rotating shaft 5 having a circular cross section having a smaller diameter than the raised portion 7 is disposed coaxially with the raised portion 7. Further, both ends of the both ends of the fixed rotating shaft 5 are integrally fixed to the end faces 7a of the respective raised portions 7. When the other substrate 2b is provided with the both ends of the rotating shaft 5, as shown in Fig. 5, in the same manner as this, the both ends of the rotating shaft 5 can be integrally formed with the substrate 2b.
兩端固定轉軸5具有與基板2a、2b的長度方向平行地延伸的部分，且只要其兩端與基板2a或2b一體地固定，則未必須要配設***部7。 The both ends of the fixed rotating shaft 5 have a portion extending in parallel with the longitudinal direction of the substrates 2a and 2b, and the ridge portion 7 is not necessarily disposed as long as both ends thereof are integrally fixed to the substrate 2a or 2b.
又，該實施形態中，轉軸把持部6例如成為圓筒等筒狀，且如圖4所示，於該筒狀的轉軸把持部6的側壁設有狹縫6a，該狹縫6a係遍及與基板2a、2b的長度方向平行的其軸線方向的全長而延伸。 Moreover, in this embodiment, the shaft gripping portion 6 is formed into a cylindrical shape such as a cylinder, and as shown in Fig. 4, a slit 6a is provided in the side wall of the cylindrical shaft gripping portion 6, and the slit 6a is spread over the same. The longitudinal direction of the substrates 2a and 2b extends parallel to the entire length in the axial direction.
筒狀的轉軸把持部6的該狹縫6a具有如下寬度尺寸：當將兩端固定轉軸5嵌入至轉軸把持部6時，能供兩端固定轉軸5通過。例如，當轉軸把持部6由容許有某種程度的彈性變形的塑膠等材料構成時，狹縫6a的寬度亦可小於具有圓形剖面的棒狀的兩端固定轉軸5的直徑。關於轉軸把持部6的狹縫6a，自防止轉軸把持部6無意地脫離兩端固定轉軸5的觀點出發，較佳為，如圖所示，將該狹縫6a設於設有該轉軸把持部6的基板2a或2b的外側面S側的位置，從而使該外側面S側形成有開口。 The slit 6a of the cylindrical shaft holding portion 6 has a width dimension such that when the both ends of the fixed rotating shaft 5 are fitted to the rotating shaft holding portion 6, the rotating shaft 5 can be fixed to both ends. For example, when the shaft grip portion 6 is made of a material such as plastic that allows a certain degree of elastic deformation, the width of the slit 6a may be smaller than the diameter of the rod-shaped both ends of the fixed shaft 5 having a circular cross section. The slit 6a of the spindle grip portion 6 is preferably provided with the spindle gripping portion 6 from the viewpoint of preventing the spindle gripping portion 6 from being unintentionally released from the both ends of the rotating shaft 5. The position of the outer surface S side of the substrate 2a or 2b of 6 is such that an opening is formed on the side of the outer side surface S.
此外，於上述***部7或轉軸把持部6的外周面，為了降低材料成本、輕量化及其他目的，可設置貫通的或非貫通的孔部。 Further, on the outer peripheral surface of the raised portion 7 or the rotating shaft grip portion 6, a through or non-penetrating hole portion may be provided in order to reduce material cost, weight, and other purposes.
此種活頁裝訂具1中，亦可將各個半環部分3a及3b與各個基板2a及2b設為獨立的構件，且於基板2a、2b成形後，將該等半環部分3a及3b固定於該等各基板2a及2b，但為了進一步減少構件個數，較佳為將各半環部分3a及3b均一體地形成於各基板2a及2b。 In the loose-leaf binding device 1, the respective half-ring portions 3a and 3b and the respective substrates 2a and 2b may be independent members, and after the substrates 2a and 2b are formed, the half-ring portions 3a and 3b may be fixed to In order to further reduce the number of members, it is preferable that each of the half-ring portions 3a and 3b is integrally formed on each of the substrates 2a and 2b.
此情況下，於利用射出成形等而形成一個板構件8a與另一板構件8b之後，藉由將該等樹脂製的兩個板構件8a相互組合，能以較少的構件個數、更容易地製造出活頁裝訂具1，上述一板構件8a具有一個基板2a、以及一體地形成於該基板2a的半環部分3a及兩端固定轉軸5或轉軸把持部6，上 述另一板構件8b具有另一基板2b、以及一體地形成於該基板2b的半環部分3a及轉軸把持部6或兩端固定轉軸5。 In this case, after the one plate member 8a and the other plate member 8b are formed by injection molding or the like, by combining the two plate members 8a made of resin, it is possible to reduce the number of components by a small number. The loose-leaf binding device 1 is manufactured, and the one plate member 8a has a substrate 2a, a half ring portion 3a integrally formed on the substrate 2a, and a fixed shaft 5 or a shaft holding portion 6 at both ends. The other plate member 8b has another substrate 2b, and a half ring portion 3a integrally formed on the substrate 2b, a shaft holding portion 6, or both ends of the rotating shaft 5.
本發明中，如圖示之實施形態所示，可設置對於兩塊基板2a、2b向使該等成對的半環部分3a及3b彼此分離的朝向施力的彈性構件9。因此，能容易地進行半環部分3a、3b的開閉操作，從而能提升操作性。 In the present invention, as shown in the illustrated embodiment, the elastic member 9 for biasing the two substrates 2a and 2b so as to separate the pair of half ring portions 3a and 3b from each other can be provided. Therefore, the opening and closing operations of the half ring portions 3a and 3b can be easily performed, and the operability can be improved.
如圖6(a)及(b)之正視圖及平面圖的例示所示，該彈性構件9適宜設為螺旋彈簧、亦即所謂扭轉螺旋彈簧，該螺旋彈簧設有：本體部9a，其係由沿軸線方向複數次呈螺旋狀捲繞的以金屬等製造的捲線構成；及腳部9b、9c，其係使該本體部9a的軸線方向的兩端部的捲起始端及捲末端各自較之線圈外周更朝向半徑方向外側、大致呈直線地延長而成。 As shown in the front view and the plan view of Figs. 6(a) and (b), the elastic member 9 is suitably a coil spring, that is, a so-called torsion coil spring, and the coil spring is provided with a body portion 9a which is composed of a winding wire made of metal or the like wound in a spiral shape in the axial direction; and the leg portions 9b and 9c each having a winding start end and a winding end of the both end portions of the main body portion 9a in the axial direction The outer circumference of the coil is further extended in a substantially straight line toward the outer side in the radial direction.
當設置此種扭轉螺旋彈簧9時，例如，可藉由如下方式配置，亦即，如圖7所示，於基板2a、2b的長度方向的中央區域，在基板2a、2b的背面B側，使扭轉螺旋彈簧9之中心軸線位於與基板2a、2b的長度方向平行的朝向，並且，使扭轉螺旋彈簧9之腳部9b及9c分別進入形成於各基板2a及2b之內側面的槽部。 When such a torsion coil spring 9 is provided, for example, it can be disposed as follows, that is, as shown in FIG. 7, in the central portion in the longitudinal direction of the substrates 2a, 2b, on the back side B side of the substrates 2a, 2b, The central axis of the torsion coil spring 9 is oriented in parallel with the longitudinal direction of the substrates 2a and 2b, and the leg portions 9b and 9c of the torsion coil spring 9 are respectively introduced into the groove portions formed on the inner side surfaces of the respective substrates 2a and 2b.
作為彈性構件，除了上述扭轉螺旋彈簧之外，亦可如圖8所示，設為無腳部的螺旋彈簧19等。就該無腳部的螺旋彈簧而言，於實際使用狀態下，若解除後述的鎖定機構，則因被卡在半環部分3a、3b的活頁紙張或封面等的自重，而使半環部分3a、3b自動地移動至打開位置。 As the elastic member, in addition to the torsion coil spring described above, as shown in FIG. 8, a coil spring 19 having no leg portion or the like may be used. In the coil spring without the leg portion, when the lock mechanism described later is released in the actual use state, the half ring portion 3a is caused by the weight of the loose leaf or the cover of the half ring portions 3a and 3b. , 3b automatically moves to the open position.
此外，此處，為了保持螺旋彈簧等彈性構件9，於與彈性構件9的配設區域鄰接的各個***部7，設有懸臂姿勢的定位桿7b，該懸臂姿勢的定位桿7b係於自該***部7之端面突出、而使如圖所示之基板2a、2b相互鄰接 配置的狀態下，以彼此對向的朝向延伸。此情況下，能利用於彈性構件9內側延伸之各定位桿7b保持彈性構件9，又，***部7亦可作為彈性構件9的彈簧座部發揮功能。 Here, in order to hold the elastic member 9 such as a coil spring, a positioning lever 7b in a cantilever posture is provided in each of the raised portions 7 adjacent to the arrangement region of the elastic member 9, and the positioning lever 7b in the cantilever posture is attached thereto. The end faces of the ridges 7 are protruded so that the substrates 2a, 2b as shown in the drawing are adjacent to each other In the configured state, the directions are opposite to each other. In this case, the elastic member 9 can be held by the positioning rods 7b extending inside the elastic member 9, and the raised portion 7 can also function as a spring seat portion of the elastic member 9.
又，本發明中，亦可設置多種形態的鎖定機構，該鎖定機構係將成對的半環部分3a、3b彼此限制於關閉位置。 Further, in the present invention, a plurality of types of locking mechanisms may be provided which restrict the pair of half ring portions 3a, 3b to each other in the closed position.
作為該鎖定機構之一例，於該實施形態下，採用如圖9所示的、設於基板2a、2b側的板鎖定機構10。 As an example of the lock mechanism, in this embodiment, the plate lock mechanism 10 provided on the sides of the substrates 2a and 2b as shown in Fig. 9 is used.
具體而言，該板鎖定機構10係由L字狀的曲臂部分10a與臂固定部分10b構成；該L字狀的曲臂部分10a係設於一個基板2a的表面F，且於較之其他區域低幾階的凹陷區域，以自該凹陷區域凸起的狀態朝另一基板2b側突出、且其中途向沿基板2a、2b的長度方向的朝向彎折；該臂固定部分10b係在設於另一基板2b的表面F的相同的凹陷區域、自該凹陷區域***。 Specifically, the plate locking mechanism 10 is constituted by an L-shaped curved arm portion 10a and an arm fixing portion 10b; the L-shaped curved arm portion 10a is provided on the surface F of one substrate 2a, and is compared with other The recessed area of the lower order of the area protrudes toward the other substrate 2b from the state of being raised from the recessed area, and is bent toward the longitudinal direction of the substrates 2a, 2b; the arm fixing portion 10b is provided The same recessed region of the surface F of the other substrate 2b is raised from the recessed region.
又，例如，藉由將臂固定部分10b的、位於一個基板2a側的面，設成自凹陷區域***的高度朝向該一個基板2a側逐漸減小的傾斜面等，從而，若使基板2a、2b自圖9(a)所示之半環部分3a、3b的打開位置轉動移位，則如圖9(b)所示，曲臂部分10a自身會產生彈性變形，且隨之越過臂固定部分10b而與臂固定部分10b卡合，從而，能使基板2a、2b彼此鎖定於半環部分3a、3b的關閉位置。 Further, for example, the surface of the arm fixing portion 10b on the side of one substrate 2a is provided as an inclined surface which gradually decreases from the height of the recessed portion toward the one substrate 2a side, and thus, the substrate 2a, 2b is rotationally displaced from the open position of the half ring portions 3a, 3b shown in Fig. 9(a), as shown in Fig. 9(b), the arm portion 10a itself is elastically deformed, and then passes over the arm fixing portion. 10b is engaged with the arm fixing portion 10b, whereby the substrates 2a, 2b can be locked to each other in the closed position of the half ring portions 3a, 3b.
當解除上述板鎖定機構10之鎖定時，可藉由如下方式進行：使基板2a、2b彼此抵抗如上文所述的螺旋彈簧及其他彈性構件9的長度方向上的施力，如圖9(c)的箭頭所示沿長度方向相對移位，從而，使 曲臂部分10a脫離臂固定部分10b。 When the locking of the above-described panel locking mechanism 10 is released, it can be performed by causing the substrates 2a, 2b to resist each other in the longitudinal direction of the coil spring and other elastic members 9 as described above, as shown in Fig. 9(c). ) the arrow is relatively displaced along the length direction, thereby The arm portion 10a is detached from the arm fixing portion 10b.
為了使基板2a、2b能如此地相對移位，可使轉軸把持部6的軸線方向長度Lh與使基板2a、2b相對移位的距離相應地、且如圖示之實施形態所示地短於兩端固定轉軸5的軸線方向長度Ls。 In order to allow the substrates 2a and 2b to be relatively displaced in this manner, the axial length Lh of the spindle gripping portion 6 can be made shorter than the distance in which the substrates 2a and 2b are relatively displaced, and is shorter than that shown in the illustrated embodiment. The axial length Ls of the rotating shaft 5 is fixed at both ends.
此外，此處，作為板鎖定機構10，例如可於基板2a、2b的長度方向上，在彼此鄰接的半環部分3a、3b之間設置有一處以上。又，亦可於一個基板2a側設置臂固定部分10b，而於另一基板2b側設置曲臂部分10a。 Further, here, as the plate lock mechanism 10, for example, one or more of the half ring portions 3a and 3b adjacent to each other may be provided in the longitudinal direction of the substrates 2a and 2b. Further, the arm fixing portion 10b may be provided on one substrate 2a side, and the crank arm portion 10a may be provided on the other substrate 2b side.
作為該其他鎖定機構，可如圖10及圖11之例示所示，與上述板鎖定機構10一同、或代替該板鎖定機構10，而於一個基板2a或另一基板2b側的轉軸把持部6或***部7設置突起部分20a、且於另一基板2b或一個基板2a側的***部7或轉軸把持部6設置突起卡合部分20b。 As the other locking mechanism, as shown in FIGS. 10 and 11, the shaft holding portion 6 on the side of one substrate 2a or the other substrate 2b may be used together with or in place of the plate locking mechanism 10. The ridge portion 7 is provided with the protruding portion 20a, and the ridge portion 7 or the shaft holding portion 6 on the other substrate 2b or the one substrate 2a side is provided with the protrusion engaging portion 20b.
圖10所示之突起部分20a係在一體形成於一個基板2a的轉軸把持部6的端面6b、且於該端面6b的圓周方向的一部分自端面6b突出，根據圖10(c)之圖式可知，該突起部分20a具有相對於該端面6b而傾斜的傾斜面、及沿轉軸把持部6的軸線方向直立的抵接面。 The projection portion 20a shown in Fig. 10 is integrally formed on the end surface 6b of the rotation shaft holding portion 6 of the one substrate 2a, and a portion of the end surface 6b in the circumferential direction protrudes from the end surface 6b, as shown in the diagram of Fig. 10(c). The protruding portion 20a has an inclined surface that is inclined with respect to the end surface 6b, and an abutting surface that stands up in the axial direction of the rotating shaft grip portion 6.
又，圖11所示之突起卡合部分20b係藉由去除如下端面7a的一部分而形成、且成為自該端面7a凹陷的形狀，該端面7a係指一體形成於另一基板2a上的***部7的端面7a中的、在基板2a、2b的組裝狀態下與設有上述突起部分20a的轉軸把持部6的端面6b對向的端面7a。又，此處之凹陷狀的突起卡合部分20b係如圖11(c)所示，具有沿圓柱狀的***部7的軸線方向的階差狀的抵接面。 Further, the projection engagement portion 20b shown in Fig. 11 is formed by removing a part of the end surface 7a which is recessed from the end surface 7a, and the end surface 7a is a ridge formed integrally on the other substrate 2a. Of the end faces 7a of the seventh end, the end faces 7a facing the end faces 6b of the rotating shaft gripping portions 6 on which the protruding portions 20a are provided in the assembled state of the substrates 2a and 2b. Moreover, the recessed protrusion engagement portion 20b here has a stepped contact surface in the axial direction of the columnar ridge portion 7 as shown in Fig. 11(c).
根據圖10及圖11所示之鎖定機構，若為了自半環部分3a、 3b打開的位置移動至半環部分3a、3b關閉的位置而使基板2a、2b轉動移位，則當另一基板2b的***部端面7a在一個基板2a之轉軸把持部端面6b上所設之突起部分20a的上述傾斜面上滑動之後，如圖12中之裝訂具1的背面圖所示，設於另一基板2b側的***部端面7a上的突起卡合部分20b的上述抵接面與一個基板2a側的突起部分20a的上述抵接面接觸，因此，兩個基板2a、2b被鎖定，其向半環部分3a、3b打開的方向的轉動移位受限制。 According to the locking mechanism shown in Figs. 10 and 11, if it is for the self-half ring portion 3a, When the position of 3b is moved to the position where the half ring portions 3a, 3b are closed and the substrates 2a, 2b are rotationally displaced, the end surface 7a of the ridge portion of the other substrate 2b is provided on the end face 6b of the pivot portion of the substrate 2a. After sliding on the inclined surface of the protruding portion 20a, as shown in the rear view of the binding device 1 in Fig. 12, the abutting surface of the protruding engaging portion 20b provided on the end surface 7a of the ridge portion on the other substrate 2b side is The abutting faces of the projecting portions 20a on one side of the substrate 2a are in contact with each other, and therefore, the two substrates 2a, 2b are locked, and the rotational displacement in the direction in which the half ring portions 3a, 3b are opened is restricted.
又，該鎖定機構中，當使半環部分3a、3b自關閉位置向打開位置移動時，藉由使基板2a、2b相對地沿長度方向移位，能解除上述突起部分20a及突起卡合部分20b各自的抵接面的接觸狀態，從而解除鎖定。 Further, in the lock mechanism, when the half ring portions 3a, 3b are moved from the closed position to the open position, the projection portions 20a and the projection engagement portions can be released by relatively shifting the substrates 2a, 2b in the longitudinal direction. The contact state of each of the abutting faces of 20b is released.
此外，此種活頁裝訂具1中，當半環部分3a、3b已自圖13(a)所示之關閉位置移動至圖13(b)所示之打開位置時，半環部分3a、3b最大程度地打開的該打開位置下的、成對的半環部分3a、3b的開度θ較佳為，圍繞兩端固定轉軸5的中心軸線測量為90°~180°的範圍。藉由使該開度θ處於該範圍內，能無任何障礙地對於裝訂具1裝卸未圖示之活頁紙張，且能有效地防止半環部分3a、3b於打開位置時活頁紙張無意地脫離。 Further, in the loose-leaf binder 1, when the half ring portions 3a, 3b have moved from the closed position shown in Fig. 13 (a) to the open position shown in Fig. 13 (b), the half ring portions 3a, 3b are the largest. The opening degree θ of the pair of half ring portions 3a, 3b in the open position to the extent that it is opened is preferably in the range of 90 to 180 degrees around the central axis of the fixed shaft 5 at both ends. By setting the opening degree θ within the range, the loose-leaf paper (not shown) can be attached and detached to the binding tool 1 without any hindrance, and the loose-leaf paper can be effectively prevented from being detached when the half-ring portions 3a and 3b are in the open position.
為了限定半環部分3a、3b的上述開度θ，例如，根據圖5(b)以及圖13(a)及(b)之圖式可知，可於***部7的外周面及/或轉軸把持部6的外周面，設置姿勢為自該外周面突出的至少一個止動凸部12。該止動凸部12可於複數個***部7及轉軸把持部6中的任意部位設置任意個，但於圖示之實施形態中，係如圖5(b)所示，於兩個***部7中之每一個設有兩個止動凸部12。或者，雖省略圖示，但亦可於設在各基板2a、2b的圓筒狀的夾持部分11a、11b各自的外周面設置止動凸部。 In order to define the above-described opening degree θ of the half ring portions 3a, 3b, for example, according to the drawings of Fig. 5(b) and Figs. 13(a) and (b), the outer peripheral surface and/or the shaft of the ridge portion 7 can be held. The outer peripheral surface of the portion 6 is provided with at least one stopper projection 12 projecting from the outer peripheral surface. The stopper projection 12 may be provided in any of a plurality of the ridge portions 7 and the shaft grip portion 6, but in the illustrated embodiment, as shown in FIG. 5(b), the ridge portions are formed in the two ridge portions. Each of the seven 7 is provided with two stopper projections 12. Alternatively, although not shown, a stopper convex portion may be provided on the outer circumferential surface of each of the cylindrical sandwiching portions 11a and 11b provided in each of the substrates 2a and 2b.
於在另一基板2b側的***部7設有止動凸部12的實施形態中，止動凸部12係如圖13(b)所示，當半環部分3a、3b向打開位置移動時抵接於一個基板2a的背面B，藉此，能發揮如下功能：限定半環部分3a、3b不會超過特定的開度θ而打開。 In the embodiment in which the swell portion 7 on the side of the other substrate 2b is provided with the stopper projection 12, the stopper projection 12 is as shown in Fig. 13(b), and when the half ring portions 3a, 3b are moved toward the open position. Abutting on the back surface B of one of the substrates 2a, it is possible to function to define that the half ring portions 3a, 3b are opened without exceeding a specific opening degree θ.
此外，作為止動凸部12的形狀，自***部7的外周面及/或轉軸把持部6的外周面突出的高度可根據限定的開度θ的大小而決定，又，止動凸部12對於基板2a或2b的抵接處可成為與該基板的背面匹配的平坦面。 Further, as the shape of the stopper convex portion 12, the height from the outer circumferential surface of the swelled portion 7 and/or the outer circumferential surface of the rotation shaft grip portion 6 can be determined according to the size of the defined opening degree θ, and the stopper convex portion 12 is further determined. The abutment of the substrate 2a or 2b can be a flat surface matching the back surface of the substrate.
當操作如上所述之活頁裝訂具1時，如圖14(a)所示，於半環部分3a、3b處於關閉位置之狀態下，例如，抓住設於各個基板2a、2b的長度方向的端部的各個夾持部分11a、11b，以上述方式抵抗扭轉螺旋彈簧9的軸線方向上的施力，而使兩塊基板2a、2b彼此沿長度方向相對移位，從而解除板鎖定機構10對基板2a、2b的限制姿勢。 When the loose-leaf binder 1 as described above is operated, as shown in FIG. 14(a), in a state where the half-ring portions 3a, 3b are in the closed position, for example, the longitudinal direction of each of the substrates 2a, 2b is grasped. The respective clamping portions 11a, 11b of the end portions resist the urging force in the axial direction of the torsion coil spring 9 in the above-described manner, and the two substrates 2a, 2b are relatively displaced from each other in the longitudinal direction, thereby releasing the pair of the plate locking mechanisms 10 The restricted posture of the substrates 2a, 2b.
因此，受到扭轉螺旋彈簧9的腳部9b、9c的施力的基板2a、2b係隨著保持各兩端固定轉軸5的各轉軸把持部6圍繞各自的兩端固定轉軸5的滑動移位，而自動地圍繞兩端固定轉軸5轉動移位。 Therefore, the substrates 2a and 2b subjected to the urging force of the leg portions 9b and 9c of the torsion coil spring 9 are slidably displaced by the rotation shafts 5 of the respective rotation shafts 5 that hold the respective rotation shafts 5 of the both ends of the rotation shaft 5. The rotation of the rotating shaft 5 is automatically fixed around the both ends.
結果，如圖14(b)所示，與基板2a、2b的上述轉動移位同時，成對的半環部分3a、3b的前端部4a、4b相互分離，移動至打開位置，從而成為活頁裝訂具1打開的狀態。於此狀態下，能對於活頁裝訂具1裝卸紙張。 As a result, as shown in Fig. 14 (b), at the same time as the above-described rotational displacement of the substrates 2a, 2b, the front end portions 4a, 4b of the pair of half ring portions 3a, 3b are separated from each other and moved to the open position, thereby becoming a loose-leaf binding. With 1 open state. In this state, the paper can be loaded and unloaded for the loose-leaf binding device 1.
又，如圖14(b)所示，於半環部分3a、3b處於打開位置的狀態下，若抓住夾持部分11a、11b，使基板2a、2b圍繞兩端固定轉軸5而轉動移位，則板鎖定機構10的曲臂部分10a會越過臂固定部分10b而鎖定，從而，能使半環部分3a、3b保持於圖14(a)所示之關閉位置。於此狀態 下，被半環部分3a、3b卡住的紙張保持於成為圓環狀的半環部分3a、3b且得以合訂。 Further, as shown in Fig. 14 (b), in a state where the half ring portions 3a, 3b are in the open position, if the holding portions 11a, 11b are grasped, the substrates 2a, 2b are fixedly rotated around the both ends to be rotated and displaced. Then, the arm portion 10a of the plate locking mechanism 10 is locked over the arm fixing portion 10b, so that the half ring portions 3a, 3b can be held in the closed position shown in Fig. 14 (a). In this state Next, the paper sheets caught by the half ring portions 3a, 3b are held in the annular half ring portions 3a, 3b and are stapled.
