Description
本発明は、可撓性表示装置の折り畳み機構に関し、更に詳細には、左右端末が閉じた状態において液晶の折り曲げ部に十分な弛みを確保しながら端末接合部に隙間がなく、且つ折り畳み機構が単一のカバー部材で覆われている可撓性表示装置の折り畳み機構に関する。 The present invention relates to a folding mechanism for a flexible display device, and more specifically, to a folding mechanism for a flexible display device that has sufficient slack in the bent portion of the liquid crystal when the left and right terminals are closed, has no gaps in the terminal joints, and is covered by a single cover member.
スマートフォン又はタブレット等の板状の端末に液晶ディスプレイと操作又は設定のためのボタンなどを備えた携帯端末装置において、液晶ディスプレイ（以下、単に「液晶」という。）を含む端末全体が２つに折り畳むことができるように構成された折り畳み式携帯端末装置（以下、「フォルダブル端末装置」という。）が知られている（例えば、非特許文献１を参照。）。 Among mobile terminal devices that are flat-shaped terminals such as smartphones or tablets equipped with a liquid crystal display and buttons for operation or settings, there are known foldable mobile terminal devices (hereinafter referred to as "foldable terminal devices") that are configured so that the entire terminal including the liquid crystal display (hereinafter simply referred to as "LCD") can be folded in two (see, for example, Non-Patent Document 1).
図１１は、従来のフォルダブル端末装置を示す概念説明図である。図１１（ａ）は左右端末が完全に閉じた状態を表し、図１１（ｂ）は左右端末が完全に開いた状態を表している。
図１１（ａ）に示されるように、このフォルダブル端末装置においては、左右端末が閉じた状態では液晶の折曲げ近傍に曲げ痕が付かないように、液晶はＲを付けて（弛みを付けて）折り曲がっている。液晶は、片側につき２つのＲ１及びＲ２で折り曲げられストレート部（Ｒ＝∞）に連続している。
11 is a conceptual explanatory diagram showing a conventional foldable terminal device, in which Fig. 11(a) shows a state in which the left and right terminals are completely closed, and Fig. 11(b) shows a state in which the left and right terminals are completely open.
As shown in Fig. 11(a), in this foldable terminal device, the liquid crystal is bent with R (slack) so that there is no bending mark near the bend of the liquid crystal when the left and right terminals are closed. The liquid crystal is bent at two R1 and R2 on each side and continues to a straight part (R = ∞).
また、左右端末の折り畳み機構については、係合部材と、左右アーム部材と、左右回転部材と、左右円弧部材と、主カバー部材とを備えて構成されている。左右アーム部材は左端末、右端末にそれぞれ固定されながら、係合部材の凸レールにそれぞれ係合している。左右回転部材は、左アーム部材上の回転軸、右アーム部材上の回転軸の回りにそれぞれ回転することができると共に、左円弧部材、右円弧部材にリンク部材（図示せず）を介してそれぞれ係合している。また、左右円弧部材は、左右端末の開閉動作に連動して開閉するように構成されている。 The folding mechanism for the left and right terminals is configured with an engagement member, left and right arm members, left and right rotating members, left and right arc members, and a main cover member. The left and right arm members are fixed to the left and right terminals, respectively, and engage with the convex rails of the engagement member. The left and right rotating members can rotate around the rotation axis on the left arm member and the rotation axis on the right arm member, respectively, and are engaged with the left arc member and the right arc member via link members (not shown). The left and right arc members are configured to open and close in conjunction with the opening and closing operations of the left and right terminals.
上記折り畳み機構の動作を簡単に説明すると、左右端末がそれぞれ開く→左右アーム部材は、係合部材の凸レールに沿ってそれぞれスライドする→左右アーム部材は、左右円弧部材をそれぞれ押す→左右回転部材は、左液晶受け面、右液晶受け面をそれぞれ押し上げる→左右液晶受け面が係合部材の段差部にそれぞれ嵌まる→左右液晶受け面および係合部材の上面がほぼ面一になる。 To briefly explain how the folding mechanism works, the left and right terminals open → the left and right arm members slide along the convex rails of the engagement member → the left and right arm members push the left and right arc members → the left and right rotating members push up the left and right LCD receiving surfaces, respectively → the left and right LCD receiving surfaces fit into the stepped portions of the engagement member → the left and right LCD receiving surfaces and the top surfaces of the engagement member become roughly flush.
また、左右端末が完全に閉じた状態では、上記折り畳み機構は主カバー部材と左右円弧部材によって覆われている。そのため、外部から折り畳み機構を視認することはできないようになっている。 In addition, when the left and right terminals are completely closed, the folding mechanism is covered by the main cover member and the left and right arc members. Therefore, the folding mechanism cannot be seen from the outside.
図１１（ｂ）に示されるように、左右端末が完全に開いた状態では液晶は平面状態になる。 As shown in Figure 11(b), when the left and right terminals are fully open, the liquid crystal is in a flat state.
図１２は、従来の他のフォルダブル端末装置を示す概念説明図である。図１２（ａ）は左右端末が完全に閉じた状態を表し、図１２（ｂ）は左右端末が完全に開いた状態を表している。 Figure 12 is a conceptual diagram showing another conventional foldable terminal device. Figure 12(a) shows the left and right terminals in a completely closed state, and Figure 12(b) shows the left and right terminals in a completely open state.
図１２（ａ）に示されるように、この従来のフォルダブル端末装置では、左右端末が端末接合線に関しそれぞれ互いに逆向き傾斜して係合部材に係合している。液晶は、片側につき１つのＲで折り曲げられ、ストレート部（Ｒ＝∞）に連続している。図から明らかな通り、左右端末が完全に閉じた状態では、液晶の折り曲げ近傍において隙間が生じている。 As shown in FIG. 12(a), in this conventional foldable terminal device, the left and right terminals are inclined in opposite directions with respect to the terminal joining line and engage with the engagement member. The liquid crystal is bent at one R on each side and continues to a straight section (R=∞). As is clear from the figure, when the left and right terminals are completely closed, a gap is created near the bend in the liquid crystal.
また、左右端末の折り畳み機構については、図１１の折り畳み機構から左右回転部材と左右円弧部材に係る機構を除いたものと考えられる。 The folding mechanism for the left and right terminals is considered to be the folding mechanism in FIG. 11 minus the mechanisms related to the left and right rotating members and left and right arc members.
また、左右端末が完全に閉じた状態では、上記折り畳み機構は単一のカバー部材によって覆われている。従って、左右端末が完全に閉じた状態では、外部から上記折り畳み機構を視認することができないようになっている。端末の折り曲げ部分が単一のカバー部材によって覆われているため、端末の折り曲げ部分の外観は好ましい。因みに、非特許文献１に記載のフォルダブル端末装置は、図１２に示されるフォルダブル端末装置の部類に属するものと考えられる。 In addition, when the left and right terminals are completely closed, the folding mechanism is covered by a single cover member. Therefore, when the left and right terminals are completely closed, the folding mechanism cannot be seen from the outside. Since the folded portion of the terminal is covered by a single cover member, the appearance of the folded portion of the terminal is favorable. Incidentally, the foldable terminal device described in Non-Patent Document 1 is considered to belong to the category of foldable terminal devices shown in FIG. 12.
図１１に示される従来のフォルダブル端末装置では、折り畳み機構が、主カバー部材と左右円弧部材という３つの部材によって覆われている。そのため、フォルダブル端末装置の折り曲げ部分についての外観が損なわれるという問題がある。 In the conventional foldable terminal device shown in FIG. 11, the folding mechanism is covered by three members: the main cover member and the left and right arc members. This causes a problem in that the appearance of the folded part of the foldable terminal device is marred.
また、図１１（ｂ）に示されるように、左右アーム部材に左右円弧部材と干渉しないようにするための切り欠きをそれぞれ形成する必要がある。 In addition, as shown in FIG. 11(b), it is necessary to form a notch in each of the left and right arm members to prevent interference with the left and right arc members.
さらに、左右端末を完全に（９０°に）開く場合に、液晶を受けるための液晶受け面を別途設ける必要がある。 In addition, when the left and right terminals are opened completely (90 degrees), a separate LCD receiving surface must be provided to receive the LCD.
ところで、図１１のフォルダブル端末装置において、折り畳み機構を単一のカバー部材で覆うため、主カバー部材を、左右円弧部材を覆うまで周方向に拡張させることが考えられる。 In the foldable terminal device of FIG. 11, in order to cover the folding mechanism with a single cover member, it is conceivable to expand the main cover member in the circumferential direction until it covers the left and right arc members.
しかし、この場合拡張した主カバー部材が左右アーム部材にそれぞれ干渉し、左右端末を完全に（９０°に）開くことができないという問題がある。 However, in this case, the extended main cover member interferes with the left and right arm members, respectively, and the left and right terminals cannot be opened completely (90°).
さらに、図１１のフォルダブル端末装置において、主カバー部材の長さはそのままで、左右円弧部材を廃止することが考えられる。 Furthermore, in the foldable terminal device of FIG. 11, it is conceivable to eliminate the left and right arc members while keeping the length of the main cover member the same.
しかし、この場合左右端末が完全に閉じた状態で、端末折り曲げ部分（背面部分）において開口が生じ、その開口を通して折り曲げ機構の内部が外部から視認されるという問題がある。 However, in this case, when the left and right terminals are completely closed, an opening is created in the terminal folding portion (back portion), and the inside of the folding mechanism can be seen from the outside through this opening, which is a problem.
他方、図１２に示される従来のフォルダブル端末装置は、折り畳み機構が単一のカバーで覆われているため、図１１に示されるフォルダブル端末装置に係る上記問題は生じない。 On the other hand, the conventional foldable terminal device shown in FIG. 12 does not have the above-mentioned problems associated with the foldable terminal device shown in FIG. 11 because the folding mechanism is covered by a single cover.
しかし、図１２に示される従来のフォルダブル端末装置では、左右端末が閉じたときに左右端末は中心線に関しそれぞれ傾斜して配置されるため、左右端末が閉じた状態で液晶の折り曲げ部分に隙間が生じるという問題がある。 However, in the conventional foldable terminal device shown in FIG. 12, when the left and right terminals are closed, they are arranged at an angle relative to the center line, which creates a problem in that gaps are created in the folded parts of the liquid crystal when the left and right terminals are closed.
そこで本発明は、上記従来技術の問題点に鑑み成されたものであり、その目的は、左右端末が閉じた状態において液晶の折り曲げ部に十分な弛みを確保しながら端末接合部に隙間がなく、且つ折り畳み機構が単一のカバー部材で覆われている可撓性表示装置の折り畳み機構を提供することである。 The present invention was developed in consideration of the problems with the above-mentioned conventional technology, and its purpose is to provide a folding mechanism for a flexible display device that ensures sufficient slack in the folded portion of the liquid crystal when the left and right terminals are closed, has no gaps in the terminal joints, and is covered by a single cover member.
上記目的を達成するための本発明に係る可撓性表示装置の折り畳み機構は、液晶等の可撓性表示装置（７０）と、前記可撓性表示装置（７０）に関連する電子基板を収容する左右対称に配置された第１端末（１）および第２端末（２）とを有する携帯端末装置（１００）を二つに折り畳むことが可能な折り畳み機構であって、前記第１端末（１）と前記第２端末（２）が閉じた状態で前記第１端末（１）と前記第２端末（２）との間の開口を覆う半円筒状のカバー部材（１０）と、前記カバー部材（１０）の外側に分離して配置され前記第１端末（１）又は第２端末（２）に一体化して所定の第１回転中心（２１Ｌ、２１Ｒ）の回りを回転可能である第１回転部材（１１）と、一部が前記カバー部材（１０）の内側をスライドしながら起立状態から寝た状態に姿勢を変化させ、且つ所定の第２回転中心（２２Ｌ、２２Ｒ）の回りを回転可能である第２回転部材（１２）と、前記第１端末（１）と前記第２端末（２）の開閉動作と同期して前記第１回転部材（１１）と前記第２回転部材（１２）とを連動させるリンク機構（１３、１３’、２３Ｌ、２３Ｒ、２４、１４）とを備えていることを特徴とする。 The folding mechanism for a flexible display device according to the present invention, which is intended to achieve the above object, is a folding mechanism capable of folding in two a mobile terminal device (100) having a flexible display device (70) such as a liquid crystal display device, and a first terminal (1) and a second terminal (2) arranged symmetrically on the left and right sides and housing an electronic board related to the flexible display device (70), and the folding mechanism comprises a semi-cylindrical cover member (10) that covers an opening between the first terminal (1) and the second terminal (2) when the first terminal (1) and the second terminal (2) are closed, and a semi-cylindrical cover member (10) that is arranged separately on the outside of the cover member (10) and covers the opening between the first terminal (1) and the second terminal (2). Or, the device is characterized by having a first rotating member (11) that is integrated with the second terminal (2) and can rotate around a predetermined first rotation center (21L, 21R), a second rotating member (12) that changes its posture from an upright state to a lying state while a part of it slides inside the cover member (10) and can rotate around a predetermined second rotation center (22L, 22R), and a link mechanism (13, 13', 23L, 23R, 24, 14) that links the first rotating member (11) and the second rotating member (12) in synchronization with the opening and closing operations of the first terminal (1) and the second terminal (2).
上記構成では、端末（１、２）に一体化した第１回転部材（１１）がカバー部材（１０）の外側に分離して配置されているため、第１回転部材（１１）の回転動作軌跡がカバー部材（１０）に干渉しなくなる。また、第１回転部材（１１）は、リンク機構（１３、１３’、２３Ｌ、２３Ｒ、２４、１４）を介して第２回転部材（１２）に連結している。従って、第２回転部材（１２）及びリンク機構の動作軌跡がカバー部材（１０）に干渉しないようにこれらの形状を構成することにより、折り畳み機構を単一のカバー部材（１０）で覆うことが可能となる。 In the above configuration, the first rotating member (11) integrated with the terminals (1, 2) is arranged separately outside the cover member (10), so that the rotational movement trajectory of the first rotating member (11) does not interfere with the cover member (10). In addition, the first rotating member (11) is connected to the second rotating member (12) via the link mechanism (13, 13', 23L, 23R, 24, 14). Therefore, by configuring the shapes of the second rotating member (12) and the link mechanism so that their movement trajectories do not interfere with the cover member (10), it is possible to cover the folding mechanism with a single cover member (10).
本発明に係る可撓性表示装置の折り畳み機構の第２の特徴は、前記第２回転部材（１２）が、前記カバー部材（１０）の内側をスライド係合する下半第２回転部材（１２Ｌ）と前記リンク機構（１３）に係合する上半第２回転部材（１２Ｕ）とを基にして構成されていることである。 The second feature of the folding mechanism of the flexible display device according to the present invention is that the second rotating member (12) is constructed based on a lower half second rotating member (12L) that slides and engages with the inside of the cover member (10) and an upper half second rotating member (12U) that engages with the link mechanism (13).
上記構成では、第２回転部材（１２）を下半回転部材（１２Ｌ）と上半回転部材（１２Ｕ）から成る２部品分離構造とすることが可能となる。 The above configuration makes it possible to make the second rotating member (12) into a two-part separate structure consisting of a lower half rotating member (12L) and an upper half rotating member (12U).
本発明に係る可撓性表示装置の折り畳み機構の第３の特徴は、前記下半第２回転部材（１２Ｌ）と前記上半第２回転部材（１２Ｕ）は互いに分離して、自身より薄い部材（５、６）によって連結されていることである。 The third feature of the folding mechanism of the flexible display device according to the present invention is that the lower half second rotating member (12L) and the upper half second rotating member (12U) are separate from each other and connected by members (5, 6) that are thinner than the lower half second rotating member (12L) and the upper half second rotating member (12U).
上記構成では、第２回転部材（１２）が寝た状態で上半第２回転部材（１２Ｕ）と下半第２回転部材（１２Ｌ）との間にカバー部材（１０）の上端が位置するようにし、第２回転部材（１２）の動作軌跡がカバー部材（１０）に干渉しないように構成することが可能となる。 In the above configuration, when the second rotating member (12) is in a lying position, the upper end of the cover member (10) is positioned between the upper half second rotating member (12U) and the lower half second rotating member (12L), making it possible to configure the movement trajectory of the second rotating member (12) so as not to interfere with the cover member (10).
本発明に係る可撓性表示装置の折り畳み機構の第４の特徴は、前記カバー部材（１０）の内側には、前記下半第２回転部材（１２Ｌ）がスライド係合する係合部材（１７、１８）が固定されていることである。 The fourth feature of the folding mechanism of the flexible display device according to the present invention is that the cover member (10) has an engagement member (17, 18) fixed inside, with which the lower half second rotating member (12L) slides and engages.

上記構成では、端末（１、２）の開閉動作と同期させて第２回転部材（１２）をより安定に動作させることが可能となる。 The above configuration makes it possible to operate the second rotating member (12) more stably by synchronizing it with the opening and closing operations of the terminals (1, 2).
本発明に係る可撓性表示装置の折り畳み機構の第６の特徴は、前記下半第２回転部材（１２Ｌ）と前記第１係合部材（１７ａ）又は前記第２係合部材（１８）は、円弧状のレール（１２ａ、１７ａ、１８ａ）に沿って凹凸嵌合していることである。 The sixth feature of the folding mechanism of the flexible display device according to the present invention is that the lower-half second rotating member (12L) and the first engaging member (17a) or the second engaging member (18) are engaged with each other along an arc-shaped rail (12a, 17a, 18a).
上記構成では、第２回転部材（１２）は第２回転中心（２２Ｌ、２２Ｒ）の回りを回転しながら第１係合部材（１７）と第２係合部材（１８）をスライドすることが可能となる。 In the above configuration, the second rotating member (12) can slide the first engaging member (17) and the second engaging member (18) while rotating around the second rotation center (22L, 22R).

上記構成では、第３回転部材（１３）はカバー部材（１０）に干渉することなく、第２回転部材（１２）に係合しながら回転軸（２３Ｌ、２３Ｒ）の回りを回転することが可能となる。これにより、端末（１、２）の開閉動作と同期して第１回転部材（１１）と第２回転部材（１２）を連動させることが可能となる。 In the above configuration, the third rotating member (13) can rotate around the rotating shaft (23L, 23R) while engaging with the second rotating member (12) without interfering with the cover member (10). This makes it possible to link the first rotating member (11) and the second rotating member (12) in synchronization with the opening and closing operations of the terminals (1, 2).

本発明に係る可撓性表示装置の折り畳み機構の第１４の特徴は、前記第２回転部材（１２）の前記下半第２回転部材（１２Ｌ）の両側面には円弧状スリット（１２ａ、１２ａ）がそれぞれ形成され、前記第１係合部材（１７）の前記下半第２回転部材（１２Ｌ）に対向する側面には前記円弧状スリット（１２ａ）に嵌合する円弧状ボス（１７ａ）が形成され、前記第２係合部材（１８）の前記下半第２回転部材（１２Ｌ）に対向する側面には前記円弧状スリット（１２ａ）に嵌合する円弧状ボス（１８ａ）が形成されていることである。 The fourteenth feature of the folding mechanism of the flexible display device according to the present invention is that arc-shaped slits (12a, 12a) are formed on both sides of the lower-half second rotating member (12L) of the second rotating member (12), an arc-shaped boss (17a) that fits into the arc-shaped slit (12a) is formed on the side of the first engaging member (17) facing the lower-half second rotating member (12L), and an arc-shaped boss (18a) that fits into the arc-shaped slit (12a) is formed on the side of the second engaging member (18) facing the lower-half second rotating member (12L).
上記構成では、端末（１、２）の開閉動作と同期させて下半第２回転部材（１２Ｌ）を第１係合部材（１７）と第２係合部材（１８）に係合しながら、第１係合部材（１７）と第２係合部材（１８）との間を安定にスライドさせることが可能となる。下半第２回転部材（１２Ｌ）の表面は可撓性表示装置を受ける受け面になることができるため、従来の折り畳み機構が備えていた液晶受け面を省略することが可能となる。 In the above configuration, the lower-half second rotating member (12L) can be engaged with the first engaging member (17) and the second engaging member (18) in synchronization with the opening and closing operations of the terminals (1, 2), while being slid stably between the first engaging member (17) and the second engaging member (18). Since the surface of the lower-half second rotating member (12L) can be used as a receiving surface for receiving a flexible display device, it is possible to omit the liquid crystal receiving surface that is provided in conventional folding mechanisms.
本発明の可撓性表示装置の折り畳み機構によれば、左右端末が閉じた状態において液晶の折り曲げ部に十分な弛みを確保しながら端末接合部に隙間がなく、且つ折り畳み機構が単一のカバー部材で覆われている可撓性表示装置の折り畳み機構にすることが可能となる。 The folding mechanism of the flexible display device of the present invention makes it possible to provide a folding mechanism for a flexible display device that has sufficient slack in the bent portion of the liquid crystal when the left and right terminals are closed, has no gaps in the terminal joints, and is covered by a single cover member.
以下、添付図面を参照して本発明の実施形態を詳細に説明する。 The following describes in detail an embodiment of the present invention with reference to the attached drawings.
図１及び図２は、本発明の一実施形態に係るフォルダブル端末装置１００を示す説明図である。なお、図１はフォルダブル端末装置１００が完全に開いた状態を示す斜視図である。図２はフォルダブル端末装置１００が完全に閉じた状態を示す縦断面図である。また、説明の都合上、左端末１及び右端末２に収容される電子部品・電子基板および液晶等については図示されていない。 Figures 1 and 2 are explanatory diagrams showing a foldable terminal device 100 according to one embodiment of the present invention. Note that Figure 1 is a perspective view showing the foldable terminal device 100 in a completely open state. Figure 2 is a vertical cross-sectional view showing the foldable terminal device 100 in a completely closed state. Also, for convenience of explanation, electronic components, electronic boards, liquid crystal, etc. housed in the left terminal 1 and right terminal 2 are not shown.
図２に示されるように、このフォルダブル端末装置１００は、液晶を含む端末全体を２つに折り畳むことが可能であり、スマートフォン、タブレット又はモバイルコンピュータ等の携帯端末装置として使用される。このフォルダブル端末装置１００の特徴としては、左右端末を完全に閉じたときに端末接合部に隙間がなく、動作ユニット部５０の折り畳み機構が単一のカバー部材１０で覆われている。また、左右端末が完全に閉じたときに動作ユニット部５０において液晶の曲げ癖が付かないように十分な弛み（２つの円弧部Ｒ１,Ｒ２）を持たせて液晶を折り畳むことができるように、このフォルダブル端末装置１００は構成されている。 As shown in FIG. 2, this foldable terminal device 100 can fold the entire terminal including the liquid crystal display in two, and is used as a portable terminal device such as a smartphone, tablet, or mobile computer. The foldable terminal device 100 is characterized in that when the left and right terminals are completely closed, there is no gap at the terminal joint, and the folding mechanism of the operating unit part 50 is covered by a single cover member 10. In addition, this foldable terminal device 100 is configured so that when the left and right terminals are completely closed, the liquid crystal display can be folded with sufficient slack (two arc parts R1, R2) so that the liquid crystal display does not develop a bending habit in the operating unit part 50.
なお、詳細については図３から図６を参照しながら後述するが、左右端末１，２を開閉させる同一の折り畳み機構が左右に一組ずつ配置されている。左端末１又は右端末２に一体化される左右の第１回転部材１１は、それぞれ左第１回転軸２１Ｌ、右第１回転軸２１Ｒを中心として回転される。他方、左右端末１,２が開く際に液晶７０を受ける左右の第２回転部材１２は、第１係合部材１７に凹凸嵌合し所定の円弧レールをスライドしながら左第２回転軸２２Ｌ又は右第２回転軸２２Ｒを中心として回転される。そして、第１回転部材１１と第２回転部材１２は、左第３回転軸２３Ｌ又は右第３回転軸２３Ｒを中心として回転される第３回転部材１３にそれぞれ係合している。 The details will be described later with reference to Figs. 3 to 6, but a pair of identical folding mechanisms for opening and closing the left and right terminals 1 and 2 are arranged on each side. The left and right first rotating members 11 integrated with the left terminal 1 or the right terminal 2 are rotated around the left first rotating shaft 21L and the right first rotating shaft 21R, respectively. On the other hand, the left and right second rotating members 12 that receive the liquid crystal 70 when the left and right terminals 1 and 2 are opened are rotated around the left second rotating shaft 22L or the right second rotating shaft 22R while sliding on a predetermined arc rail while engaging with the first engaging member 17 in a concave-convex manner. The first rotating member 11 and the second rotating member 12 are engaged with the third rotating member 13 that is rotated around the left third rotating shaft 23L or the right third rotating shaft 23R, respectively.
このように、このフォルダブル端末装置１００では左右端末１,２に一体化される第１回転部材１１は第１係合部材１７に係合するのではなく、第１回転部材１１にリンクした第３回転部材１３を介して第２回転部材１２が第１係合部材１７に係合するように構成されている。 In this way, in this foldable terminal device 100, the first rotating member 11 integrated with the left and right terminals 1 and 2 does not engage with the first engaging member 17, but rather the second rotating member 12 engages with the first engaging member 17 via the third rotating member 13 linked to the first rotating member 11.
その結果、左右端末１,２が完全に開いたときに、左右の第１回転部材１１がカバー部材１０に干渉することがなくなる。また、左右の第３回転部材１３が、第３回転軸２３Ｌ,２３Ｒに段差板２４を介して係合することにより、第３回転部材１３はカバー部材１０に干渉することがなくなる。さらに、左右の第２回転部材１２を板によって結合された２部品分離構造とすることにより、第２回転部材１２はカバー部材１０に干渉することがなくなる。これにより、端末接合部に隙間が生じない位置に、左右端末１,２についての回転軸を設定することが可能となり、これにより、カバー部材１０を単一の部品で構成しながら、各回転部材がカバー部材１０と干渉せずに第１回転軸２１Ｌ,２１Ｒを中心とした端末開閉が可能となる。なお、第１回転軸２１Ｌ,２１Ｒ、及び第２回転軸２２Ｌ,２２Ｒは仮想軸であるのに対し、第３回転軸２３Ｌ,２３Ｒは実回転軸である。 As a result, when the left and right terminals 1, 2 are completely opened, the left and right first rotating members 11 do not interfere with the cover member 10. In addition, the left and right third rotating members 13 engage with the third rotating shafts 23L, 23R via the step plate 24, so that the third rotating members 13 do not interfere with the cover member 10. Furthermore, by making the left and right second rotating members 12 into a two-part separated structure joined by a plate, the second rotating members 12 do not interfere with the cover member 10. This makes it possible to set the rotating shafts for the left and right terminals 1, 2 at a position where no gap occurs at the terminal joint, and thus, while the cover member 10 is composed of a single part, it is possible to open and close the terminals around the first rotating shafts 21L, 21R without each rotating member interfering with the cover member 10. Note that the first rotating shafts 21L, 21R and the second rotating shafts 22L, 22R are virtual shafts, whereas the third rotating shafts 23L, 23R are real rotating shafts.
図１に示されるように、構成としては、ＣＰＵ、ＲＡＭ及びＲＯＭ等のメモリー、及びＣＣＤカメラ等の電子デバイスが集積化された各種電子基板、並びにバッテリー、スピーカー等のパワーデバイスを収容する左端末１及び右端末２と、液晶を含む端末全体を２つに折り畳む／開くことを可能にする動作ユニット部５０と、端末の開閉動作に対し適度な回転抵抗を与える上／下トルクユニット部６０Ｕ,６０Ｌと、動作ユニット部５０の回転部材（例えば第１回転部材１１）又は上／下トルクユニット部６０Ｕ,６０Ｌを左端末１及び右端末２に一体化する右固定板金３および左固定板金４と、動作ユニット部５０と上／下トルクユニット部６０Ｕ,６０Ｌとを連結する左第１／左第２連結板金５,７および右第１／右第２連結板金６,８と、動作ユニット部５０の固定部材（例えば第１係合部材１７）を固定するカバー部材１０（図２）とを具備して構成されている。なお、ここで言う動作ユニット部の回転部材とは、動作ユニット部の構成部材のうちで左右端末１,２と一緒に回転する構成部材を意味している。動作ユニット部５０の回転部材および固定部材については図３を参照しながら後述する。 As shown in FIG. 1, the device is configured to include a left terminal 1 and a right terminal 2 that house various electronic boards on which memories such as a CPU, RAM, and ROM, and electronic devices such as a CCD camera are integrated, as well as power devices such as a battery and a speaker; an operating unit section 50 that enables the entire terminal including the LCD to be folded in two/opened; up/down torque unit sections 60U, 60L that provide appropriate rotational resistance to the opening and closing operation of the terminal; right fixed metal sheets 3 and left fixed metal sheets 4 that integrate the rotating members (e.g., first rotating member 11) of the operating unit section 50 or the up/down torque unit sections 60U, 60L with the left terminal 1 and right terminal 2; first/second left connecting metal sheets 5, 7 and first/second right connecting metal sheets 6, 8 that connect the operating unit section 50 and the up/down torque unit sections 60U, 60L; and a cover member 10 (FIG. 2) that secures the fixing members (e.g., first engaging member 17) of the operating unit section 50. The rotating members of the operating unit here refer to the components of the operating unit that rotate together with the left and right terminals 1 and 2. The rotating members and fixed members of the operating unit 50 will be described later with reference to FIG. 3.
図２に戻って、上述した通り、液晶受け面となる第２回転部材１２はカバー部材１０に干渉しないように２部品が分離しながら板によって連結した２部品分離構造を成している。従って、上に位置する部品を上半第２回転部材１２Ｕと、下に位置する部品を下半第２回転部材１２Ｌとしそれぞれ区別することにする。なお、図３を参照しながら後述するが、上半第２回転部材１２Ｕは、第３回転部材１３及び第４回転部材１４に係合する一方、下半第２回転部材１２Ｌは第１係合部材１７及び第２係合部材１８に係合するようにそれぞれ構成されている。 Returning to FIG. 2, as described above, the second rotating member 12, which serves as the liquid crystal receiving surface, has a two-part separated structure in which the two parts are separated and connected by a plate so as not to interfere with the cover member 10. Therefore, the part located on the top will be distinguished as the upper-half second rotating member 12U, and the part located on the bottom as the lower-half second rotating member 12L. As will be described later with reference to FIG. 3, the upper-half second rotating member 12U engages with the third rotating member 13 and the fourth rotating member 14, while the lower-half second rotating member 12L is configured to engage with the first engaging member 17 and the second engaging member 18, respectively.
図３は、本発明に係る動作ユニット部５０を示す平面図である。なお、説明の都合上、左固定板金３及び右固定板金４についてはハッチングが施されている。同様に、左第１連結板金５、右第１連結板金６、左第２連結板金７、及び右第２連結板金８についてもハッチングが施されている。 Figure 3 is a plan view showing the operating unit section 50 according to the present invention. For ease of explanation, the left fixed metal plate 3 and the right fixed metal plate 4 are hatched. Similarly, the left first connecting metal plate 5, the right first connecting metal plate 6, the left second connecting metal plate 7, and the right second connecting metal plate 8 are also hatched.
図から明らかな通り、動作ユニット部５０では同一の折り畳み機構５０Ｒ,５０Ｌが、第１係合部材１７,１７に関して点対称に左端末１と右端末２にそれぞれ配置されている。従って、以降において動作ユニット部５０の説明については、主に図上右側の右折り畳み機構５０Ｒに基づいて説明することにする。 As is clear from the figure, in the operating unit 50, identical folding mechanisms 50R and 50L are arranged at the left terminal 1 and the right terminal 2, respectively, point-symmetrically with respect to the first engagement members 17 and 17. Therefore, hereafter, the explanation of the operating unit 50 will be mainly based on the right folding mechanism 50R on the right side of the figure.
右折り畳み機構５０Ｒは、両隣りの第３回転部材１３と第３’回転部材１３’に係合しながら右端末２と一体化して回転する第１回転部材１１と、第３回転部材１３と第１４回転部材１４に係合しながら第１係合部材１７と第２係合部材１８にも係合して液晶７０（図示せず）の受け面となる第２回転部材１２と、第１回転部材１１と第２回転部材１２に係合しながらカバー部材１０内側に実回転軸（第３回転軸２３Ｒ）を持つ第３回転部材１３と、第２回転部材１２に係合しながら右端末２と一体化して回転する第４回転部材１４と、第３’回転部材１３’と第６回転部材１６に係合しながら第２係合部材１８と第３係合部材１９にも係合して液晶７０（図示せず）の受け面となる第５回転部材１５と、第５回転部材１５と係合しながら右端末２と一体化して回転する第６回転部材１６と、第２回転部材１２と係合する第１係合部材１７と、第２回転部材１２と第５回転部材１５の双方に係合する第２係合部材１８と、第５回転部材１５に係合する第３係合部材１９と、第２回転部材１２と下トルクユニット部６０Ｌを連結する右第１連結板金６と、第５回転部材１５と上トルクユニット部６０Ｕを連結する右第２連結板金８と、第１回転部材１１、第４回転部材１４および第６回転部材１６を右端末２に一体化する右固定板金４と、第１係合部材１７、第２係合部材１８および第３係合部材１９を固定して支持するカバー部材１０（図２）とを具備して構成されている。 The right folding mechanism 50R is made up of a first rotating member 11 that rotates integrally with the right terminal 2 while engaging with the adjacent third rotating member 13 and third' rotating member 13', a second rotating member 12 that engages with the third rotating member 13 and the fourteenth rotating member 14 and also engages with the first engaging member 17 and the second engaging member 18 to form a receiving surface for the liquid crystal 70 (not shown), a third rotating member 13 that has an actual rotating axis (third rotating axis 23R) inside the cover member 10 while engaging with the first rotating member 11 and the second rotating member 12, a fourth rotating member 14 that rotates integrally with the right terminal 2 while engaging with the second rotating member 12, and a fifth rotating member 15 that engages with the third' rotating member 13' and the sixth rotating member 16 and also engages with the second engaging member 18 and the third engaging member 19 to form a receiving surface for the liquid crystal 70 (not shown). It is configured with a rotating member 15, a sixth rotating member 16 that rotates integrally with the right terminal 2 while engaging with the fifth rotating member 15, a first engaging member 17 that engages with the second rotating member 12, a second engaging member 18 that engages with both the second rotating member 12 and the fifth rotating member 15, a third engaging member 19 that engages with the fifth rotating member 15, a right first connecting sheet metal 6 that connects the second rotating member 12 to the lower torque unit part 60L, a right second connecting sheet metal 8 that connects the fifth rotating member 15 to the upper torque unit part 60U, a right fixed sheet metal 4 that integrates the first rotating member 11, the fourth rotating member 14, and the sixth rotating member 16 with the right terminal 2, and a cover member 10 (FIG. 2) that fixes and supports the first engaging member 17, the second engaging member 18, and the third engaging member 19.
第１回転部材１１、第２回転部材１２、第３回転部材１３、第４回転部材１４、第５回転部材１５、及び第１６回転部材１６、並びに右固定板金４及び右第１／右第２連結板金６,８は、カバー部材１０に対し相対回転することができる。それに対し、第１係合部材１７、第２係合部材１８及び第３係合部材１９は、カバー部材１０に対し相対回転不能である。 The first rotating member 11, the second rotating member 12, the third rotating member 13, the fourth rotating member 14, the fifth rotating member 15, and the sixteenth rotating member 16, as well as the right fixed metal plate 4 and the right first and right second connecting metal plates 6, 8, can rotate relative to the cover member 10. In contrast, the first engaging member 17, the second engaging member 18, and the third engaging member 19 cannot rotate relative to the cover member 10.
第１回転部材１１は、右固定板金４を介して右端末２に直結している。従って、第１回転部材１１は右第１回転軸２１Ｒ（図４）を中心軸に持ちながら右端末２と一体化して回転する。なお、この右第１回転軸２１Ｒは仮想軸である。これについては図４を参照しながら後述する。 The first rotating member 11 is directly connected to the right terminal 2 via the right fixed metal plate 4. Therefore, the first rotating member 11 rotates integrally with the right terminal 2 with the right first rotating shaft 21R (Fig. 4) as its central axis. Note that this right first rotating shaft 21R is a virtual axis. This will be described later with reference to Fig. 4.
また、第１回転部材１１の第３回転部材１３に対向する側面にはスリット（凹レール）がそれぞれ形成され、その各スリットは第３係合部材１３の側面に形成された円筒ボス（凸部）に凹凸嵌合している。これについては図１０を参照しながら後述する。 In addition, slits (concave rails) are formed on the side surface of the first rotating member 11 facing the third rotating member 13, and each slit fits into a cylindrical boss (convex portion) formed on the side surface of the third engaging member 13. This will be described later with reference to Figure 10.
上半第２回転部材１２Ｕの第３回転部材１３に対向する側面には円筒ボス（凸部）が形成され、その円筒ボス（凸部）は第３回転部材１３の側面に形成されたスリット（凹レール）に係合している。同様に、上半第２回転部材１２Ｕの第４回転部材１４に対向する側面には円筒ボス（凸部）が形成され、その円筒ボス（凸部）は第１４回転部材１４の側面に形成されたスリット（凹レール）に係合している。これについては図１０を参照しながら後述する。 A cylindrical boss (convex portion) is formed on the side surface of the upper-half second rotating member 12U facing the third rotating member 13, and the cylindrical boss (convex portion) engages with a slit (concave rail) formed on the side surface of the third rotating member 13. Similarly, a cylindrical boss (convex portion) is formed on the side surface of the upper-half second rotating member 12U facing the fourth rotating member 14, and the cylindrical boss (convex portion) engages with a slit (concave rail) formed on the side surface of the fourteenth rotating member 14. This will be described later with reference to FIG. 10.
下半第２回転部材１２Ｌは右第２回転軸２２Ｒを中心軸に持ちながら第１係合部材１７及び第２係合部材１８にスライドしている。なお、この右第２回転軸２２Ｒは仮想軸である。これについては図５を参照しながら後述する。 The lower-half second rotating member 12L slides on the first engaging member 17 and the second engaging member 18 while holding the right-hand second rotating shaft 22R as its central axis. Note that this right-hand second rotating shaft 22R is a virtual axis. This will be described later with reference to FIG. 5.
また、下半第２回転部材１２Ｌの第１係合部材１７に対向する側面にはスリット（凹レール）が形成され、そのスリットは第１係合部材１７の側面に形成された円弧ボス（凸レール）に係合している。同様に、下半第２回転部材１２Ｌの第２係合部材１８に対向する側面にはスリット（凹レール）が形成され、そのスリットは第２係合部材１８の側面に形成された円弧ボス（凸レール）に係合している。これについては図１０を参照しながら後述する。 In addition, a slit (concave rail) is formed on the side surface of the lower-half second rotating member 12L facing the first engaging member 17, and the slit engages with an arc boss (convex rail) formed on the side surface of the first engaging member 17. Similarly, a slit (concave rail) is formed on the side surface of the lower-half second rotating member 12L facing the second engaging member 18, and the slit engages with an arc boss (convex rail) formed on the side surface of the second engaging member 18. This will be described later with reference to Figure 10.
なお、第５回転部材１５についても、第２回転部材１２と同様な機能・構成であり、上半第５回転部材１５Ｕ及び下半第５回転部材１５Ｌが右第２連結板金８によって連結した２部品分離構造を成している。 The fifth rotating member 15 has the same function and configuration as the second rotating member 12, and has a two-part separated structure in which the upper-half fifth rotating member 15U and the lower-half fifth rotating member 15L are connected by the right-hand second connecting sheet metal 8.
第３回転部材１３は、段差板２４上に固定されている。段差板２４は右第３回転軸２３Ｒ（図２）に相対回転自在に係合している。従って、第３回転部材１３は、右第３回転軸２３Ｒの回りに回転可能である。なお、この右第３回転軸２３Ｒは実回転軸である。これについては図６を参照しながら後述する。 The third rotating member 13 is fixed on a stepped plate 24. The stepped plate 24 is engaged with a right third rotating shaft 23R (FIG. 2) so as to be relatively rotatable. Therefore, the third rotating member 13 can rotate around the right third rotating shaft 23R. Note that this right third rotating shaft 23R is an actual rotating shaft. This will be described later with reference to FIG. 6.
また、第３回転部材１３の側面には円筒ボス（凸部）およびスリット（凹レール）が形成され、第２回転部材１２の円筒ボス（凸部）と第１回転部材１１のスリット（凹レール）にそれぞれ係合している。これについては図１０を参照しながら後述する。 The third rotating member 13 has a cylindrical boss (convex portion) and a slit (concave rail) formed on its side, which engage with the cylindrical boss (convex portion) of the second rotating member 12 and the slit (concave rail) of the first rotating member 11, respectively. This will be described later with reference to Figure 10.
なお、第３’回転部材１３’についても、第３回転部材１３と同様な機能・構成である。 The third' rotating member 13' has the same function and configuration as the third rotating member 13.
第４回転部材１４は、右固定板金４を介して右端末２に直結している。上半第２回転部材１２に対向する側面にはスリット（凹レール）が形成されている。第６回転部材１６についても第４回転部材１４と同様な構成である。なお、第６回転部材１６についても第４回転部材１４と同様な機能・構成である。 The fourth rotating member 14 is directly connected to the right terminal 2 via the right fixed metal plate 4. A slit (concave rail) is formed on the side facing the upper half second rotating member 12. The sixth rotating member 16 has a similar configuration to the fourth rotating member 14. The sixth rotating member 16 has the same function and configuration as the fourth rotating member 14.
図４は、第１回転部材１１についての回転動作を示す説明図である。なお、図４（ａ）は図３のＡ－Ａ断面図であり、同（ｂ）は左右端末１,２が完全に閉じた状態を表している。 Figure 4 is an explanatory diagram showing the rotational operation of the first rotating member 11. Note that Figure 4(a) is a cross-sectional view taken along line A-A in Figure 3, and Figure 4(b) shows the left and right terminals 1, 2 in a completely closed state.
図４（ａ）に示されるように、第１回転部材１１は、右固定板金４を介してボルト（図示せず）によって右端末２に一体化される。第１回転部材１１は、カバー部材１０の外側に分離して配置されている。つまり、第１回転部材１１はカバー部材１０の内側に係合していない。カバー部材１０の内側に係合しているのは下半第２回転部材１２Ｌである。 As shown in FIG. 4(a), the first rotating member 11 is integrated with the right terminal 2 by a bolt (not shown) via the right fixed metal plate 4. The first rotating member 11 is disposed separately on the outside of the cover member 10. In other words, the first rotating member 11 does not engage with the inside of the cover member 10. It is the lower half second rotating member 12L that engages with the inside of the cover member 10.
図４（ｂ）に示されるように、右端末２はカバー部材１０の外周面に沿ってスライドしながら右第１回転軸２１Ｒを中心として回転する。従って、右第１回転軸２１Ｒの位置については、左右端末１,２が完全に閉じた状態で液晶７０のストレート部が隙間なく接合し、左右端末１,２が完全に開いた状態で液晶７０が同一平面になる位置である。これについては図７を参照しながら後述する。 As shown in FIG. 4(b), the right terminal 2 rotates around the right first rotation shaft 21R while sliding along the outer circumferential surface of the cover member 10. Therefore, the position of the right first rotation shaft 21R is such that when the left and right terminals 1 and 2 are completely closed, the straight portions of the liquid crystal 70 are joined without any gaps, and when the left and right terminals 1 and 2 are completely open, the liquid crystal 70 is on the same plane. This will be described later with reference to FIG. 7.
図５は、第２回転部材１２についての回転動作を示す説明図である。なお、図５（ａ）は図３のＢ－Ｂ断面図であり、同（ｂ）は左右端末１,２が完全に閉じた状態を表している。 Figure 5 is an explanatory diagram showing the rotational movement of the second rotating member 12. Note that Figure 5(a) is a cross-sectional view taken along line B-B in Figure 3, and Figure 5(b) shows the left and right terminals 1, 2 in a completely closed state.
図５（ａ）に示されるように、第２回転部材１２は、上半第２回転部材１２Ｕと下半第２回転部材１２Ｌとが右第１連金板金６によって連結した２部品分離構造を成している。左右端末１,２が完全に開いた状態でカバー部材１０の縁部が右第１連結板金６に当接し、それ以外では上半第２回転部材１２Ｕ及び下半第２回転部材１２Ｌはカバー部材１０に干渉しないように構成されている。 As shown in FIG. 5(a), the second rotating member 12 has a two-part separated structure in which the upper-half second rotating member 12U and the lower-half second rotating member 12L are connected by the right-first connecting metal plate 6. When the left and right terminals 1, 2 are fully open, the edge of the cover member 10 abuts against the right-first connecting metal plate 6, and otherwise the upper-half second rotating member 12U and the lower-half second rotating member 12L are configured not to interfere with the cover member 10.
図５（ｂ）に示されるように、下半第２回転部材１２Ｌの第１係合部材１７に対向する側面には円弧状の第２スリット（凹レール）１２ａが形成されている。一方、第１係合部材１７の下半第２回転部材１２Ｌに対向する側面には、第２スリット１２ａに凹凸嵌合する第１円弧ボス１７ａが形成されている。従って、下半第２回転部材１２Ｌは、第１係合部材１７の第１円弧ボス１７ａに凹凸嵌合してスライドしながら右第２回転軸２２Ｒを中心として回転する。なお、右第２回転軸２２Ｒは、例えば第１円弧ボス１７ａの外周面に基づいて設定することができる。これについては図７を参照しながら後述する。 As shown in FIG. 5(b), a second arc-shaped slit (concave rail) 12a is formed on the side of the lower-half second rotating member 12L facing the first engaging member 17. Meanwhile, a first arc-shaped boss 17a that fits concavely into the second slit 12a is formed on the side of the first engaging member 17 facing the lower-half second rotating member 12L. Therefore, the lower-half second rotating member 12L rotates around the right second rotating shaft 22R while sliding in a concave-convex fit with the first arc-shaped boss 17a of the first engaging member 17. The right second rotating shaft 22R can be set based on the outer peripheral surface of the first arc-shaped boss 17a, for example. This will be described later with reference to FIG. 7.
このように、下半第２回転部材１２Ｌは左右端末１,２が完全に開いた状態ではカバー部材１０に干渉することはなくなる。また、左右端末１,２が完全に閉じた状態では液晶７０の円弧部に干渉しないように下半第２回転部材１２Ｌは構成されている。 In this way, the lower-half second rotating member 12L does not interfere with the cover member 10 when the left and right terminals 1, 2 are fully open. Also, the lower-half second rotating member 12L is configured so as not to interfere with the arc portion of the liquid crystal 70 when the left and right terminals 1, 2 are fully closed.
図６は、第３回転部材１３についての回転動作を示す説明図である。なお、図６（ａ）は図３のＣ－Ｃ断面図であり、同（ｂ）は左右端末１,２が完全に閉じた状態を表している。また、右端末２において第３’回転部材１３’が図示されているが、第３回転部材１３とみなして説明することにする。 Figure 6 is an explanatory diagram showing the rotational movement of the third rotating member 13. Note that Figure 6(a) is a cross-sectional view taken along line C-C in Figure 3, and Figure 6(b) shows the left and right terminals 1, 2 in a completely closed state. Also, a third' rotating member 13' is shown in the right terminal 2, but this will be considered as the third rotating member 13 in the following explanation.
図６（ａ）に示されるように、第３回転部材１３は、右第３回転軸２３Ｒに対し相対回転可能な段差板２４上に固定されている。従って、第３回転部材１３は右第３回転軸２３Ｒの回りを一定半径で回転可能である。 As shown in FIG. 6(a), the third rotating member 13 is fixed on a stepped plate 24 that is rotatable relative to the right-hand third rotating shaft 23R. Therefore, the third rotating member 13 can rotate around the right-hand third rotating shaft 23R at a constant radius.
右第３回転軸２３Ｒは、例えばカバー部材１０の内側で、且つ左右端末１,２が完全に開いた状態でカバー部材１０縁部が段差板１４に当接する位置に形成されている。これについては図７を参照しながら後述する。 The right third rotating shaft 23R is formed, for example, inside the cover member 10 and at a position where the edge of the cover member 10 abuts against the step plate 14 when the left and right terminals 1, 2 are fully open. This will be described later with reference to Figure 7.
図６（ｂ）に示されるように、段差板２４は、左右端末１,２が完全に閉じた状態で液晶７０の折り曲げ部と干渉しないように傾斜段差形状を成している。上段部は右第３回転軸２３Ｒに相対回転可能に係合すると共に、下段部は第３回転部材１３を支持・固定している。 As shown in FIG. 6(b), the step plate 24 has an inclined step shape so as not to interfere with the folded portion of the liquid crystal 70 when the left and right terminals 1, 2 are completely closed. The upper step engages with the right third rotating shaft 23R for relative rotation, and the lower step supports and fixes the third rotating member 13.
また、第３回転部材１３の先端は、左右端末１,２が完全に閉じた状態で液晶７０の折り曲げ部と干渉しないように段差板２４と逆向きに傾斜している。その為、第３回転部材１３と右第３回転軸２３Ｒとの間に液晶７０の折り曲げ部を収容するための空間が好適に確保されている。 The tip of the third rotating member 13 is inclined in the opposite direction to the step plate 24 so as not to interfere with the bent portion of the liquid crystal 70 when the left and right terminals 1, 2 are completely closed. Therefore, a space for accommodating the bent portion of the liquid crystal 70 is appropriately secured between the third rotating member 13 and the right third rotating shaft 23R.
図７は、第１回転部材１１、第２回転部材１２および第３回転部材１３の各回転軸を示す説明図である。 Figure 7 is an explanatory diagram showing the rotation axes of the first rotating member 11, the second rotating member 12, and the third rotating member 13.
図７（ａ）に示されるように、液晶７０表面の任意の点を点Ａとすると共に、液晶７０中心線と折り曲げ部との交点を点Ｂとする。第１回転部材１１の回転中心である右第１回転軸２１Ｒの位置は、例えば下記（１）および（２）を満足する定位置として求めることができる。
（１）点Ｂから点Ａに到る液晶７０の曲線の長さＬ１が、液晶７０を９０°時計方向に回転させたときの当初の点Ｂと回転後の点Ａ’を結んだ直線の長さＬ２に等しくなる。
（２）その定位置と点Ａを結ぶ直線と、その定位置と点Ａ’を結ぶ直線との成す角度が９０°である。
7A, an arbitrary point on the surface of the liquid crystal 70 is defined as point A, and an intersection point between the center line of the liquid crystal 70 and the bent portion is defined as point B. The position of the right first rotation shaft 21R, which is the rotation center of the first rotating member 11, can be determined as a fixed position that satisfies, for example, the following (1) and (2).
(1) The length L1 of the curve of the liquid crystal 70 from point B to point A is equal to the length L2 of the straight line connecting the initial point B and point A' after rotation when the liquid crystal 70 is rotated 90 degrees clockwise.
(2) The angle between the line connecting the fixed position to point A and the line connecting the fixed position to point A' is 90°.
この場合、点Ｂ又は点Ａ’から板厚ｔだけ下がった水平線が液晶受け面に相当する。従って、右固定板金４は上端面が液晶受け面に接する位置であって、液晶７０のストレート部に接する位置に設定される。カバー部材１０は上端面が液晶受け面に接する位置であって、液晶７０の中心線と自身の中心線が一致する位置に設定される。 In this case, the horizontal line that is lowered by the plate thickness t from point B or point A' corresponds to the liquid crystal receiving surface. Therefore, the right fixed metal plate 4 is set at a position where its upper end surface contacts the liquid crystal receiving surface and where it contacts the straight portion of the liquid crystal 70. The cover member 10 is set at a position where its upper end surface contacts the liquid crystal receiving surface and where its own center line coincides with the center line of the liquid crystal 70.
また、カバー部材１０の外周面の円弧形状は、左右端末１,２を開閉させた時に左右端末１,２がカバー部材１０(円弧形状部)に接触しないこと、且つ、カバー部材１０との隙間が大きくならない様に決定される。 The arc shape of the outer peripheral surface of the cover member 10 is determined so that the left and right terminals 1, 2 do not come into contact with the cover member 10 (arc-shaped portion) when the left and right terminals 1, 2 are opened and closed, and so that the gap between the cover member 10 and the left and right terminals 1, 2 is not large.
図７（ｂ）に示されるように、第２回転部材１２の回転中心である右第２回転軸２２Ｒの位置は、例えば下記（３）および（４）を満足する定位置として求めることができる。
（３）第２回転部材１２の下半第２回転部材１２Ｌの上端面が液晶受け面に接するとき、カバー部材１０に干渉することがない。
（４）その定位置を中心に回転させる場合、液晶７０の円弧部（Ｒ部）に干渉することがない。
As shown in FIG. 7B, the position of the right second rotation shaft 22R, which is the center of rotation of the second rotation member 12, can be determined as a fixed position that satisfies, for example, the following (3) and (4).
(3) When the upper end surface of the lower half second rotating member 12L of the second rotating member 12 comes into contact with the liquid crystal receiving surface, there is no interference with the cover member 10.
(4) When rotating the liquid crystal display 70 around its fixed position, the liquid crystal display 70 does not interfere with the arcuate portion (R portion).
なお、この場合、下半第２回転部材１２Ｌの第２スリット１２ａの円弧中心は右第２回転軸２２Ｒとなる。 In this case, the center of the arc of the second slit 12a of the lower-half second rotating member 12L is the right-hand second rotating shaft 22R.
図７（ｃ）に示されるように、第３回転部材１３の回転中心である右第３回転軸２３Ｒの位置は、例えば下記（５）から（７）を満足する定位置として求めることができる。
（５）カバー部材１０の内側かつ径方向外側で、軸の半径に段差板２４の板厚ｔ’を加えた位置が液晶受け面上に位置する。
（６）第３回転部材１３が第１回転部材１１と第２回転部材１２（上半第２回転部材１２Ｕ）の双方に係合することができる。
（７）第３回転部材１３の上端面が液晶受け面に接しながら液晶７０のストレート部に接する。
As shown in FIG. 7C, the position of the right third rotation shaft 23R, which is the center of rotation of the third rotation member 13, can be determined as a fixed position that satisfies, for example, the following (5) to (7).
(5) On the inner side and radially outer side of the cover member 10, the position obtained by adding the thickness t' of the step plate 24 to the axis radius is located on the liquid crystal receiving surface.
(6) The third rotating member 13 can be engaged with both the first rotating member 11 and the second rotating member 12 (upper half second rotating member 12U).
(7) The upper end face of the third rotating member 13 comes into contact with the straight portion of the liquid crystal 70 while being in contact with the liquid crystal receiving surface.
図８は、左右端末１,２が完全に開いた状態のフォルダブル端末装置１００から左端末１、左固定板金３、左第１／左第２連結部材５,７、左折り畳み機構５０Ｌ、及び上下トルクユニット部６０Ｕ,６０Ｌを除いた構成を示す説明図である。 Figure 8 is an explanatory diagram showing the configuration of the foldable terminal device 100 with the left and right terminals 1, 2 fully open, excluding the left terminal 1, the left fixed metal plate 3, the first left/second left connecting members 5, 7, the left folding mechanism 50L, and the upper and lower torque unit parts 60U, 60L.
図８に示されるように、例えば、第１回転部材１１、第４回転部材１４、及び第６回転部材１６は、右固定板金４にボルト（図示せず）によってそれぞれ固定される。そして、第４回転部材１４、第６回転部材１６は、右固定板金４を支持した状態で右端末２の取付台１２ａ,１２ａにボルト（図示せず）によってそれぞれ固定される。これによって、第１回転部材１１、第４回転部材１４及び第６回転部材１６は、右端末２に一体化されることになる。 As shown in FIG. 8, for example, the first rotating member 11, the fourth rotating member 14, and the sixth rotating member 16 are each fixed to the right fixed metal plate 4 by bolts (not shown). The fourth rotating member 14 and the sixth rotating member 16 are then each fixed to the mounting bases 12a, 12a of the right terminal 2 by bolts (not shown) while supporting the right fixed metal plate 4. As a result, the first rotating member 11, the fourth rotating member 14, and the sixth rotating member 16 are integrated into the right terminal 2.
また、第１係合部材１７、第２係合部材１８及び第３係合部材１９は、カバー１０の内側にボルト（図示せず）によってそれぞれ固定される。以下に、右折り畳み機構５０Ｒについて更に説明する。 The first engagement member 17, the second engagement member 18, and the third engagement member 19 are each fixed to the inside of the cover 10 by bolts (not shown). The right folding mechanism 50R will be further described below.
図９は、左右端末１,２が完全に開いた状態の右折り畳み機構５０Ｒを示す説明図である。なお、第１係合部材１７と第２係合部材１８との空間には、左折り畳み機構５０Ｌ（図３）の第２回転部材１２の下半第２回転部材１２Ｌが嵌ることになる。 Figure 9 is an explanatory diagram showing the right folding mechanism 50R in a state where the left and right terminals 1, 2 are fully open. The space between the first engagement member 17 and the second engagement member 18 is where the lower half second rotating member 12L of the second rotating member 12 of the left folding mechanism 50L (Figure 3) fits.
図９に示されるように、右第３回転軸２３Ｒは、第１係合部材１７と第２係合部材１８との間に設けられ、両端が第１係合部材１７と第２係合部材１８にそれぞれ固定されている。 As shown in FIG. 9, the right third rotating shaft 23R is disposed between the first engaging member 17 and the second engaging member 18, and both ends are fixed to the first engaging member 17 and the second engaging member 18, respectively.
右第３回転軸２３Ｒには、段差板２４が相対回転可能に取り付けられている。段差板２４は上段で右第３回転軸２３Ｒに係合し、下段に第３回転部材１３及び第３’回転部材１３’がボルト（図示せず）によって固定されている。なお、第１回転部材１１は段差板２４に何ら係合していない、段差板２４に対しフリー状態である。 A step plate 24 is attached to the right third rotating shaft 23R so as to be capable of relative rotation. The step plate 24 engages with the right third rotating shaft 23R at the upper stage, and the third rotating member 13 and the third' rotating member 13' are fixed to the lower stage by bolts (not shown). The first rotating member 11 is not engaged with the step plate 24 in any way and is free relative to the step plate 24.
第３回転部材１３の図上左隣りには第２回転部材１２の上半第２回転部材１２Ｕが、第３回転部材１３と第４回転部材１４の双方に係合可能に、且つ下半第２回転部材１２Ｌが第１係合部材１７と第２係合部材１８の双方にスライド可能に設けられている。そして、上半第２連結部材１２Ｕと下半第２連結部材１２Ｌは右第２連結板金８によって一体に連結されている。 To the left of the third rotating member 13 in the figure, the upper half second rotating member 12U of the second rotating member 12 is provided so as to be engageable with both the third rotating member 13 and the fourth rotating member 14, and the lower half second rotating member 12L is provided so as to be slidable on both the first engaging member 17 and the second engaging member 18. The upper half second connecting member 12U and the lower half second connecting member 12L are connected together by the right second connecting sheet metal 8.
第２回転部材１２は、右第２連結板金８によって下トルクユニット部６０Ｌ（図１）に連結している。従って、第２回転部材１２は下トルクユニット部６０Ｌによってスライド位置（回転位置）が保持される場合、第２回転部材１２に係合している第３回転部材１３の回転位置が保持される。これにより、第３回転部材１３に係合している第１回転部材１１の回転位置が保持されるようになる。その結果、右端末２の回転位置が保持されるようになる。 The second rotating member 12 is connected to the lower torque unit part 60L (Figure 1) by the right second connecting sheet metal 8. Therefore, when the second rotating member 12 is held in a sliding position (rotational position) by the lower torque unit part 60L, the rotational position of the third rotating member 13 engaged with the second rotating member 12 is held. This causes the rotational position of the first rotating member 11 engaged with the third rotating member 13 to be held. As a result, the rotational position of the right terminal 2 is held.
同様に、第３’回転部材１３’の図上右隣りには第５回転軸１５の上半第５回転部材１５Ｕが、第３’回転部材１３’と第６回転部材１６の双方に係合可能に、且つ下半第５回転部材１５Ｌが第２係合部材１８と第３係合部材１９の双方にスライド可能に設けられている。 Similarly, to the right of the third' rotating member 13' in the figure, the upper half fifth rotating member 15U of the fifth rotating shaft 15 is provided so as to be engageable with both the third' rotating member 13' and the sixth rotating member 16, and the lower half fifth rotating member 15L is provided so as to be slidable with both the second engaging member 18 and the third engaging member 19.
第５回転部材１５は、右第１連結板金６によって上トルクユニット部６０Ｕ（図１）に連結している。従って、第５回転部材１５は上トルクユニット部６０Ｕによってスライド位置（回転位置）が保持される場合、第５回転部材１５に係合している第３’回転部材１３’の回転位置が保持される。これにより、第３’回転部材１３’に係合している第１回転部材１１の回転位置が保持されるようになる。その結果、右端末２は、第５回転部材１５によっても回転位置が保持されるようになる。以下に、隣り合う回転部材の係合、回転部材と係合部材との係合について説明する。 The fifth rotating member 15 is connected to the upper torque unit part 60U (Fig. 1) by the right first connecting sheet metal 6. Therefore, when the fifth rotating member 15 is held in a sliding position (rotational position) by the upper torque unit part 60U, the rotational position of the third' rotating member 13' engaged with the fifth rotating member 15 is held. This causes the rotational position of the first rotating member 11 engaged with the third' rotating member 13' to be held. As a result, the rotational position of the right terminal 2 is also held by the fifth rotating member 15. The engagement of adjacent rotating members and the engagement between the rotating members and the engaging members are described below.
図１０は、左右端末１,２が完全に開いた状態の右折り畳み機構５０Ｒの隣り合う回転部材の係合、並びに回転部材と係合部材との係合を示す説明図である。なお、説明の都合上、第３回転部材１３、第３’回転部材１３’、第４回転部材１４及び第６回転部材１６についてはその係合相手から分離してそれぞれ表されている。 Figure 10 is an explanatory diagram showing the engagement of adjacent rotating members of the right folding mechanism 50R when the left and right terminals 1, 2 are fully open, as well as the engagement of the rotating members with the engaging members. For ease of explanation, the third rotating member 13, the third' rotating member 13', the fourth rotating member 14, and the sixth rotating member 16 are each shown separated from their engaging counterparts.
第１回転部材１１の第３回転部材１３に対向する側面には、円弧状の第１スリット１１ａが形成されている。一方、第１回転部材１１の第３’回転部材１３’に対向する側面には、円弧状の第１’スリット１１ａ’（図示せず）が形成されている。 A first arc-shaped slit 11a is formed on the side surface of the first rotating member 11 facing the third rotating member 13. On the other hand, a first arc-shaped slit 11a' (not shown) is formed on the side surface of the first rotating member 11 facing the third rotating member 13'.
第３回転部材１３の第１回転部材１１に対向する側面には、第１スリット１１ａに嵌合する第３円筒ボス１３ｂが形成されている。一方、第３回転部材１３の第１係合部材１１とは反対側の側面には、上半第２回転部材１２Ｕの第２円筒ボス１２ｂに嵌合する第３スリット１３ａが形成されている。 A third cylindrical boss 13b that fits into the first slit 11a is formed on the side of the third rotating member 13 facing the first rotating member 11. On the other hand, a third slit 13a that fits into the second cylindrical boss 12b of the upper half second rotating member 12U is formed on the side of the third rotating member 13 opposite the first engaging member 11.
同様に、第３’回転部材１３’の第１回転部材１１に対向する側面には、第１回転部材１１の第１’スリット１１ａ’（図示せず）に嵌合する第３’円筒ボス１３ｂ’が形成されている。一方、第３’回転部材１３’の第１係合部材１１とは反対側の側面には、上半第５回転部材１５Ｕの第５円筒ボス１５ｂに嵌合する第３’スリット１３ａ’（図示せず）が形成されている。 Similarly, a third' cylindrical boss 13b' is formed on the side of the third' rotating member 13' facing the first rotating member 11, which fits into the first' slit 11a' (not shown) of the first rotating member 11. Meanwhile, a third' slit 13a' (not shown) is formed on the side of the third' rotating member 13' opposite the first engaging member 11, which fits into the fifth cylindrical boss 15b of the upper half fifth rotating member 15U.
上半第２回転部材１２Ｕの第３回転部材１３に対向する側面には、第３スリット１３ａに嵌合する第２円筒ボス１２ｂが形成されている。一方、第３回転部材１３とは反対側の側面には、第４回転部材１４の第４スリット１４ａ（図示せず）に嵌合する第２’円筒ボス１２ｂ’が形成されている。 A second cylindrical boss 12b that fits into the third slit 13a is formed on the side of the upper-half second rotating member 12U that faces the third rotating member 13. On the other hand, a second' cylindrical boss 12b' that fits into the fourth slit 14a (not shown) of the fourth rotating member 14 is formed on the side opposite the third rotating member 13.
同様に、上半第５回転部材１５Ｕの第３’回転部材１３’に対向する側面には、第３’スリット１３ａ’（図示せず）に嵌合する第５円筒ボス１５ｂが形成されている。一方、第３’回転部材１３’とは反対側の側面には、第６回転部材１６の第６スリット１６ａに嵌合する第５’円筒ボス１５ｂ’が形成されている。 Similarly, a fifth cylindrical boss 15b that fits into the third slit 13a' (not shown) is formed on the side of the upper-half fifth rotating member 15U that faces the third rotating member 13'. Meanwhile, a fifth cylindrical boss 15b' that fits into the sixth slit 16a of the sixth rotating member 16 is formed on the side opposite the third rotating member 13'.
第４回転部材１４は右固定板金４（図８）を介して右端末２に一体化されている。第４回転部材１４の上半第２回転部材１２Ｕに対向する側面には、第２’円筒ボス１２ｂ’に嵌合する第４スリット１４ａ（図示せず）が形成されている。 The fourth rotating member 14 is integrated with the right terminal 2 via the right fixed metal plate 4 (Figure 8). A fourth slit 14a (not shown) that fits into the second' cylindrical boss 12b' is formed on the side of the fourth rotating member 14 facing the upper half second rotating member 12U.
同様に、第６回転部材１６は右固定板金４（図８）を介して右端末２に一体化されている。第６回転部材１６の上半第５回転部材１５Ｕに対向する側面には、第５’円筒ボス１５ｂ’に嵌合する第６スリット１６ａが形成されている。以上が隣り合う回転部材の係合である。以下に回転部材と係合部材との係合について説明する。 Similarly, the sixth rotating member 16 is integrated with the right terminal 2 via the right fixed metal plate 4 (Figure 8). A sixth slit 16a that fits into the fifth' cylindrical boss 15b' is formed on the side surface of the sixth rotating member 16 facing the upper half fifth rotating member 15U. This is how adjacent rotating members engage. The engagement between the rotating members and the engaging member is explained below.
下半第２回転部材１２Ｌの第１係合部材１７に対向する側面には、第１係合部材１７の第１円弧ボス１７ａに嵌合する円弧状の第２スリット１２ａが形成されている。一方、第１係合部材１７とは反対側の側面には、第２係合部材１８の第２円弧ボス１８ａに嵌合する円弧状の第２スリット１２ａが形成されている。 A second arc-shaped slit 12a is formed on the side of the lower-half second rotating member 12L facing the first engaging member 17, which fits into the first arc-shaped boss 17a of the first engaging member 17. On the other hand, a second arc-shaped slit 12a is formed on the side opposite the first engaging member 17, which fits into the second arc-shaped boss 18a of the second engaging member 18.
同様に、下半第５回転部材１５Ｌの第２係合部材１８に対向する側面には、第２係合部材１８の第２円弧ボス１８ａに嵌合する円弧状の第５スリット１５ａが形成されている。一方、第２係合部材１８とは反対側の側面には、第３係合部材１９の第３円弧ボス１９ａに嵌合する円弧状の第５スリット１５ａが形成されている。 Similarly, a fifth arc-shaped slit 15a that fits into the second arc-shaped boss 18a of the second engagement member 18 is formed on the side surface of the lower-half fifth rotating member 15L facing the second engagement member 18. On the other hand, a fifth arc-shaped slit 15a that fits into the third arc-shaped boss 19a of the third engagement member 19 is formed on the side surface opposite the second engagement member 18.
