Description
【０００１】[0001]
本考案は、開閉体を備えた電子手帳やハンディタイプのワープロやパソコン等 に好適な開閉装置に関する。 The present invention relates to an opening / closing device suitable for an electronic notebook, a handy type word processor, a personal computer or the like having an opening / closing body.
【０００２】[0002]
従来から、電子手帳やハンディタイプのワープロやパソコン等の機器として、 表示手段等を具備した開閉体を、装置本体に重ね合わせた閉鎖位置と、装置本体 の一側部を中心に所定角度回動させて傾斜状に立起させた開放位置にと亙って位 置切換え可能に構成したものが広く市販されており、この種の機器に用いられる 開閉装置として、開閉体を回動操作した位置に保持させるための制動手段と、閉 鎖位置から開放側への所定角度の範囲内において開閉体を開放方向に弾性付勢す る付勢手段とを備えたものが実用化されている。 Conventionally, as devices such as electronic notebooks, handy-type word processors and personal computers, an opening / closing body equipped with a display means and the like is rotated at a predetermined angle around the closed position where the device body is superposed and one side part of the device body. There is a wide range of products on the market that can be switched to a different position from the open position that is raised in an inclined manner. A braking means for holding the opening / closing body and a biasing means for elastically biasing the opening / closing body in the opening direction within a range of a predetermined angle from the closed position to the opening side have been put into practical use.
【０００３】 前記開閉装置としては、例えば、図１７に示すように、装置本体の本体フレー ム１００に固定されたブラケット部材１０１に軸部材１０２を回転自在に枢支し 、軸部材１０２の右端部を開閉体１０３に相対回転不能に連結し、軸部材１０２ を介して開閉体１０３を本体フレーム１００に回動自在に支持するとともに、軸 部材１０２の左部に制動用コイルバネ１０４を外嵌状に装着し、制動用コイルバ ネ１０４の内周面を軸部材１０２の外周面に圧接させ、制動用コイルバネ１０４ の一端をブラケット部材１０１に固定して他端を自由端となし、軸部材１０２の 右部に付勢用コイルバネ１０５を外嵌状に装着し、付勢用コイルバネ１０５の一 端を軸部材１０２に固定し、他端を閉鎖位置から開放側への所定角度の範囲内に おいてブラケット部材１０１又は本体フレーム１００側に係合するように配置さ せたものが提案されている。As the opening / closing device, for example, as shown in FIG. 17, a shaft member 102 is rotatably supported by a bracket member 101 fixed to a body frame 100 of the device body, and a right end portion of the shaft member 102 is rotatably supported. Is connected to the opening / closing body 103 in a relatively non-rotatable manner, the opening / closing body 103 is rotatably supported by the main body frame 100 via the shaft member 102, and the braking coil spring 104 is externally fitted to the left part of the shaft member 102. After mounting, the inner peripheral surface of the braking coil panel 104 is pressed against the outer peripheral surface of the shaft member 102, one end of the braking coil spring 104 is fixed to the bracket member 101, and the other end is a free end. A biasing coil spring 105 is externally fitted to the portion, one end of the biasing coil spring 105 is fixed to the shaft member 102, and the other end is within a predetermined angle range from the closed position to the open side. In addition, it is proposed that the bracket member 101 or the body frame 100 is arranged so as to be engaged with the bracket member 101 or the body frame 100 side.
【０００４】 前記開閉装置では、開閉体１０３を閉鎖方向へ操作したときに、制動用コイル バネ１０４が締めつけられるように設定され、開放方向に対しては比較的容易に 操作出来るが、閉鎖方向に対しては制動用コイルバネ１０４で軸部材１０２が保 持されて大きな制動力が作用するように構成され、また、開閉体１０３の閉鎖位 置から開放側への所定角度の範囲内において付勢用コイルバネ１０５が捩じられ て、開閉体１０３に開放方向へのバネ力が作用するように構成されている。In the opening / closing device, when the opening / closing body 103 is operated in the closing direction, the braking coil spring 104 is set so as to be tightened, and it can be operated relatively easily in the opening direction, but in the closing direction. On the other hand, the braking coil spring 104 holds the shaft member 102 so that a large braking force is exerted, and the opening / closing body 103 is biased within a predetermined angle range from the closed position to the open side. The coil spring 105 is twisted so that a spring force in the opening direction acts on the opening / closing body 103.
【０００５】[0005]
ところが、前記開閉装置では、閉鎖位置から開放側への所定角度の範囲外にお いて、付勢用コイルバネの他端はブラケット部材又は本体フレームから離間し、 付勢用コイルバネは自由状態に保持されているので、閉鎖位置から開放側への所 定角度の範囲内における付勢用コイルバネの僅かな捩じりにより、開閉体に対し て大きなバネ力を作用させるためには、バネ定数の大きなコイルバネを採用する 必要があり、その分付勢手段が大型化するという問題が発生する。 また、軸部材に対する制動用コイルバネの圧接力により開閉体に対して制動力 を付与するので、軸部材と制動用コイルバネの成形精度を高く設定する必要があ ること、僅かな成形精度の誤差により開閉体への制動力が大きく変動するので、 制動力に対するバラツキが大きくなること、コイルバネにより制動力を付与する ので制動手段が大型化すること、などの問題がある。 However, in the opening / closing device, the other end of the biasing coil spring is separated from the bracket member or the main body frame outside the range of the predetermined angle from the closed position to the opening side, and the biasing coil spring is held in a free state. Therefore, in order to apply a large spring force to the opening / closing body by slightly twisting the biasing coil spring within the range of the fixed angle from the closed position to the open side, a coil spring with a large spring constant is used. Therefore, there is a problem in that the energizing means becomes large accordingly. Further, since the braking force is applied to the opening / closing body by the pressure contact force of the braking coil spring with respect to the shaft member, it is necessary to set the molding accuracy of the shaft member and the braking coil spring to a high level, and due to a slight error in the molding accuracy. Since the braking force applied to the opening / closing body fluctuates greatly, there is a problem that the variation with respect to the braking force becomes large, and the braking force is given by the coil spring, so that the braking means becomes large.
【０００６】 本考案の目的は、開閉体を所定位置へ付勢するための充分なバネ力を確保しつ つコンパクトに構成可能な開閉装置並びに製作が容易で且つ制動力のバラツキを 低減し得る開閉装置を提供することである。An object of the present invention is to provide an opening / closing device that can be compactly configured while ensuring a sufficient spring force for urging the opening / closing body to a predetermined position, and can be easily manufactured and reduce variations in braking force. It is to provide a switchgear.

【００１９】 前記左側の第２ブラケット部１４には捩じりコイルバネ２２の左端部と係合可 能な右方へ延びる操作部（これが操作部材に相当する）２５が形成され、この操 作部２５は、開閉体２を閉鎖位置から復帰位置までの範囲内で操作している間に おいては、捩じりコイルバネ２２の左端部から離れた状態になり、開閉体２を復 帰位置から最大開放位置側へ操作すると、捩じりコイルバネ２２の左端部に係合 して、捩じりコイルバネ２２を捩じり方向へ操作するように配置されている。An operating portion (which corresponds to an operating member) 25 that extends to the right and is engageable with the left end portion of the torsion coil spring 22 is formed on the left second bracket portion 14, and the operating portion is formed. When the open / close member 2 is operated within the range from the closed position to the return position, the position 25 is separated from the left end of the torsion coil spring 22, and the open / close member 2 is moved from the return position. When operated to the maximum open position side, the left end portion of the torsion coil spring 22 is engaged so that the torsion coil spring 22 is operated in the torsion direction.
【００２０】 前記第１ブラケット部１３と左側の第２ブラケット部１４間には、閉鎖位置か ら復帰位置までの範囲内で開閉体２を操作したときに、その操作した位置に開閉 体２を保持させるため、次のような構成の制動手段２６が設けられている。Between the first bracket portion 13 and the left second bracket portion 14, when the opening / closing body 2 is operated within the range from the closed position to the return position, the opening / closing body 2 is placed at the operated position. In order to hold it, braking means 26 having the following configuration is provided.
【００２１】 図２〜図５に示すように、第１ブラケット部１３と左側の第２ブラケット部１ ４間において軸部材１６にはポリアセタールなどからなる合成樹脂材料製のスリ ーブ２１が外嵌状に装着され、スリーブ２１はＤカット部１８を介して軸部材１ ６に相対回転不能に装着され、スリーブ２１には側面視略Ｃ字状の圧接部材２７ が外嵌状に装着され、スリーブ２１の右端部には左側の第２ブラケット部１４に 形成された１対の係合切欠部２８に係合する係合凸部２９が形成され、スリーブ ２１は係合切欠部２８と係合凸部２９との係合により第２ブラケット部１４に相 対回転不能に連結され、圧接部材２７とスリーブ２１間の摩擦抵抗により開閉体 ２に対して制動力が作用するように構成されている。但し、前記捩じりコイルバ ネ２２のバネ力は制動手段２６の制動力よりも大きく設定され、開閉体２を復帰 位置から最大開放位置までの所定角度の範囲内へ操作し、この状態で開閉体２か ら手を放すと、開閉体２が復帰位置に復帰するように構成してある。As shown in FIGS. 2 to 5, a sleeve 21 made of a synthetic resin material such as polyacetal is externally fitted to the shaft member 16 between the first bracket portion 13 and the left second bracket portion 14. The sleeve 21 is mounted on the shaft member 16 via the D-cut portion 18 so as not to be rotatable relative to the shaft member 16. The sleeve 21 is fitted with a press-contact member 27 having a substantially C-shape in a side view so as to be fitted externally. An engaging protrusion 29 that engages with the pair of engaging notches 28 formed on the second bracket 14 on the left side is formed at the right end of the sleeve 21, and the sleeve 21 has an engaging protrusion 28 and an engaging protrusion 28. The second bracket portion 14 is non-rotatably connected to the second bracket portion 14 by engagement with the portion 29, and a braking force acts on the opening / closing body 2 due to frictional resistance between the pressure contact member 27 and the sleeve 21. However, the spring force of the torsion coil bar 22 is set to be larger than the braking force of the braking means 26, and the opening / closing body 2 is operated within a predetermined angle range from the return position to the maximum open position, and the opening / closing is performed in this state. When the hand is released from the body 2, the opening / closing body 2 is returned to the return position.
【００２２】 次に、前記開閉装置１０の作用について説明する。 閉鎖位置から復帰位置までの範囲内においては、制動手段２６により開閉体２ が回動操作した位置に保持されるので、開閉体２を所望の角度に保持することが 可能となって開閉体２の操作性が向上する。また、復帰位置から最大開放位置ま での範囲内においては、操作部材２５により捩じりコイルバネ２２が捩じられて 、このときのバネ力で開閉体２が復帰位置側へ復帰し、開放時における開閉装置 １０の破損が防止されることになる。Next, the operation of the opening / closing device 10 will be described. In the range from the closed position to the return position, the opening / closing body 2 is held at the position where the opening / closing body 2 is rotated by the braking means 26, so that the opening / closing body 2 can be held at a desired angle. Operability is improved. Further, within the range from the return position to the maximum open position, the torsion coil spring 22 is twisted by the operating member 25, and the opening / closing body 2 is returned to the return position side by the spring force at this time, and when opened. Therefore, the breakage of the switchgear 10 will be prevented.
【００２３】 前記制動手段２６ではスリーブ２１とスリーブ２１に外嵌装着された圧接部材 ２７間の摩擦抵抗により開閉体２に対して制動力を付与するので、スリーブ２１ 及び圧接部材２７を小型に構成しても十分な制動力が得られるとともに、圧接部 材２７のスリーブ２１に対する圧接力を調節することで制動力のバラツキを防止 出来る。しかも、スリーブ２１を偏平形状に構成することで、開閉体２の操作角 度に応じて制動力を変化させることが可能になり、開放操作の初期における制動 力を小さく設定して、開閉体２の操作性を向上することが出来る。更に、合成樹 脂材料製のスリーブ２１を抱き込むので、潤滑オイルを必要とせず、オイル切れ などによる異音の発生を確実に防止出来る。In the braking means 26, a braking force is applied to the opening / closing body 2 by the frictional resistance between the sleeve 21 and the pressure contact member 27 fitted on the sleeve 21, so that the sleeve 21 and the pressure contact member 27 can be made compact. Even if a sufficient braking force is obtained, variation in the braking force can be prevented by adjusting the pressure contact force of the pressure contact member 27 to the sleeve 21. Moreover, by configuring the sleeve 21 to have a flat shape, the braking force can be changed according to the operation angle of the opening / closing body 2, and the braking force at the initial stage of the opening operation can be set to a small value to open / close the opening / closing body 2. The operability of can be improved. Further, since the sleeve 21 made of synthetic resin material is held, lubricating oil is not required, and it is possible to reliably prevent generation of abnormal noise due to oil shortage.
【００２４】 前記捩じりコイルバネ２２は、予め捩じった状態に保持されているので、弾性 係数の比較的小さなバネでも開閉体２に対して十分なバネ力を付与することが可 能となり、比較的小型な捩じりコイルバネ２２を用いることで開閉装置１０全体 を小型に構成することが出来る。Since the torsion coil spring 22 is held in a pre-twisted state, a spring having a relatively small elastic coefficient can apply a sufficient spring force to the opening / closing body 2. By using the relatively small torsion coil spring 22, the entire opening / closing device 10 can be made small.
