上記ロック装置において、キーシリンダは、ロック解除状態から、回転体をキー操作により回転すると、ストッパが操作部材のガイド用ボス側へ移動されて操作部材の動きを規制するロック状態に切り換えられる。このような構造では、ストッパを横移動するスペースが必要となるためコンパクト化を図り難い。また、作動部材がロッドと操作部材の間に介在される２つのロータで構成されるため複雑でコンパクト化も擬制になり易い。更に、キーシリンダとしては、例えば、回転体が回転されてストッパが規制位置に移動したか否か感覚的に分からず使い勝手も悪い。 In the lock device, when the rotating body is rotated by a key operation, the key cylinder is switched from the unlocked state to the locked state in which the stopper is moved to the guide boss side of the operating member to regulate the movement of the operating member. With such a structure, it is difficult to make the stopper compact because a space for laterally moving the stopper is required. Further, since the operating member is composed of two rotors interposed between the rod and the operating member, it is complicated and compactness tends to be fictitious. Further, as the key cylinder, for example, it is not intuitively known whether or not the rotating body is rotated and the stopper is moved to the regulated position, and the usability is poor.

本発明の目的は、以上のような課題を解消して、キーシリンダにより操作部材の動きを規制するロック状態と動きを許容するロック解除状態との切換構造を簡略化したり、スペース効率に優れるようにする。加えて、キーシリンダのロック状態とロック解除状態の切換完了が感覚的に分かるようにして使い勝手を向上する。他の目的は以下の内容説明のなかで明らかにする。 An object of the present invention is to solve the above problems, to simplify the switching structure between the locked state in which the movement of the operating member is regulated by the key cylinder and the unlocked state in which the movement is allowed, and to improve the space efficiency. To. In addition, usability is improved by making it possible to intuitively understand the completion of switching between the locked state and the unlocked state of the key cylinder. Other purposes will be clarified in the following description.

揺動片６７は、ストッパ部６５同士の間に設けられて、ストッパ部６５よりも薄肉で弾性変位可能となっており、下面先端側に突出された可撓爪６７ａを有している。すなわち、キーシリンダ６は、図４のごとくストッパ部６５を被係合部３８に係合したロック状態（この状態では一方のストッパ部６５が当接面１７ｄに当接し、他方のストッパ部６５が突起部１７ｆの当接面１７ｋに当接することで回り止めされる）と、図３のごとくストッパ部６５を被係合部３８より所定角離間したロック解除状態（このときは一方のストッパ部６５が当接面１７ｅに当接することで回り止めされる）に切り換えられる。また、その際、可撓爪６７ａは、キーシリンダ６がキー操作により回転されてロック状態に至る直前に段差１８ｃに設けられた両凹凸部１８ｂの一方に沿って摺接する。また、可撓爪６７ａは、ロック解除状態に至る直前に凹凸部１８ｂの他方に沿って摺接する。これにより、この構造では、可撓爪６７ａが凹凸部１８ｂを摺接する際のクリック音を伴い、これにより節度感により使い勝手を向上できる。 Swinging piece 67 is provided between the stopper portion 6 5 together, than the stopper portion 6 5 has a resiliently displaceable thin and has a flexible pawl 67a that protrudes on the lower surface leading end side .. That is, as shown in FIG. 4, the key cylinder 6 is in a locked state in which the stopper portion 65 is engaged with the engaged portion 38 (in this state, one stopper portion 65 is in contact with the contact surface 17d, and the other stopper portion 65 is in contact with the contact surface 17d. The stopper portion 65 is separated from the engaged portion 38 by a predetermined angle (in this case, one of the stopper portions 65). Is stopped by contacting the contact surface 17e). At that time, the flexible claw 67a is slidably contacted along one of the two uneven portions 18b provided on the step 18c immediately before the key cylinder 6 is rotated by the key operation to reach the locked state. Further, the flexible claw 67a is slidably contacted along the other side of the uneven portion 18b immediately before reaching the unlocked state. As a result, in this structure, the flexible claw 67a is accompanied by a clicking sound when the concave-convex portion 18b is in sliding contact with the concave-convex portion 18b, which can improve usability due to a sense of moderation.

回動部材６３は、単独又は本体６０と連結されたキーシリンダ６の態様で、各脚片６８が回動部材受け面１８に設けられた対応するガイド溝１８ａに抜け止め可能、かつ所定角つまりこの例では９０度だけ回動可能に嵌合される。このため、この構造では、回動部材６３やキーシリンダ６がハウジング１に対して安定保持され、良好な回動作動が維持される。また、この構造では、キーシリンダ配置部１５には、キーシリンダ６と共にカバー７が組付けられる。このカバー７は、図１のごとくキーシリンダ配置部１５に取り付けられて、上段段差部１６と本体６０の間を目視不能に覆う部材である。この例では、上面に本体１０を挿入する円形孔７１を形成していると共に、両側に突設されて係合穴７４ａを形成している片７４を有している。そして、カバー７は、例えば、キーシリンダ６が内側段差部１７内と共に回動部材受け面１８に位置決めされた状態から、上段段差部１６側に対し、各係合穴７４ａを対応する係止爪１７ｂに係合することにより装着される。 The rotating member 63 is in the form of a key cylinder 6 alone or connected to the main body 60, and each leg piece 68 can be prevented from coming off in a corresponding guide groove 18a provided on the rotating member receiving surface 18, and has a predetermined angle. In this example, the fitting is rotatably fitted by 90 degrees. Therefore, in this structure, the rotating member 63 and the key cylinder 6 are stably held with respect to the housing 1, and good rotational operation is maintained. Further, in this structure, the cover 7 is attached to the key cylinder arranging portion 15 together with the key cylinder 6. The cover 7 is a member that is attached to the key cylinder arranging portion 15 as shown in FIG. 1 and invisiblely covers the space between the upper step portion 16 and the main body 60. In this example, a circular hole 71 into which the main body 10 is inserted is formed on the upper surface thereof, and a piece 74 is provided on both sides to form an engaging hole 74a. Then, for example, the cover 7 has a locking claw corresponding to each engaging hole 74a with respect to the upper step portion 16 side from the state where the key cylinder 6 is positioned on the rotating member receiving surface 18 together with the inside step portion 17. It is attached by engaging with 17b.

なお、図５において、符号７５はカバー７に類似のカバーを示している。つまり、このカバー７５は、カバー７に比べて円形孔７１を欠如しているが、それ以外はほぼ同じである。このようなカバー７５は、ロック装置として、例えばキーシリンダ６を省略するような構造に用いられる。 In FIG. 5, reference numeral 75 indicates a cover similar to the cover 7. That is, the cover 75 lacks the circular hole 71 as compared with the cover 7, but is almost the same except for the cover 7. Such a cover 75 is used as a locking device in a structure that omits, for example, the key cylinder 6.

（作動）以下、以上のように作製されたロック装置９の主な作動特徴について言及する。
（１）、図１と図２及び図３は以上のロック装置９において、キーシリンダ６がボタン２の操作を許容するロック解除状態とされ、開閉体で固定本体の開口部を覆っている開閉体の閉状態を示している。この閉状態では、ボタン２及びリンク３がばね部材Ｓ１の付勢力で上昇されてボタン配置部１０をボタン２で覆っている。ロッド４のうち、ロッド４Ａは、ばね部材Ｓ２の付勢力によりハウジング１から突出する方向へ摺動されて、先端部４１を固定本体側取付部８０の係止穴８１に係合している。ロッド４Ｂは、ばね部材Ｓ３の付勢力によりハウジング１から突出する方向へ摺動されて、先端部４４を固定本体側取付部８０の係止穴８１に係合している。 (Operating) Hereinafter, the main operating features of the locking device 9 manufactured as described above will be referred to.
(1), FIGS. 1, 2 and 3 show that in the above locking device 9, the key cylinder 6 is in an unlocked state that allows the operation of the button 2, and the opening / closing body covers the opening of the fixed body. It shows the closed state of the body. In this closed state, the button 2 and the link 3 are raised by the urging force of the spring member S1 to cover the button arrangement portion 10 with the button 2. Of the rods 4, the rod 4A is slid in a direction protruding from the housing 1 by the urging force of the spring member S2, and the tip portion 41 is engaged with the locking hole 81 of the fixed main body side mounting portion 80. The rod 4B is slid in a direction protruding from the housing 1 by the urging force of the spring member S3, and the tip portion 44 is engaged with the locking hole 81 of the fixed main body side mounting portion 80.

（２）、図１（ｂ）は開閉体が固定本体の開口部を閉じた閉状態から、開口部を開放する開状態に切り換える操作を示している。すなわち、この場合、操作者は、例えば指Ｆによりボタン２をばね部材Ｓ１の付勢力に抗して押圧操作する。すると、この構造では、リンク３がボタン２と共にハウジング１の内底面方向に押し下げられ、それと連動して各ロッド４Ａ，４Ｂがリンク３のガイド溝３５，３６及び軸４７，４８等の作動によりばね部材Ｓ２，Ｓ３の付勢力に抗してハウジング１内の没方向に移動し、先端部４１，４４が対応する係止穴８１から係合解除される。このため、操作者は、図１（ｂ）の状態から開閉体を全開方向へ回動操作することができる。 (2) and FIG. 1 (b) show an operation in which the opening / closing body switches from a closed state in which the opening of the fixed body is closed to an open state in which the opening is opened. That is, in this case, the operator presses the button 2 against the urging force of the spring member S1 by, for example, the finger F. Then, in this structure, the link 3 is pushed down together with the button 2 toward the inner bottom surface of the housing 1, and in conjunction with this, the rods 4A and 4B are springs by the operation of the guide grooves 35 and 36 and the shafts 47 and 48 of the link 3. It moves in the sinking direction in the housing 1 against the urging force of the members S2 and S3, and the tip portions 41 and 44 are disengaged from the corresponding locking holes 81. Therefore, the operator can rotate the open / close body in the fully open direction from the state shown in FIG. 1 (b).

（３）、ところで、この構造では、ボタン２に対する押圧を開放すると、リンク３及びボタン２がばね部材Ｓ１の付勢力により元の状態まで上昇される。そして、この上昇過程では、ボタン２の移動速度がダンパ８（リンクのラック２６とギア８ｂの噛み合い）により制動されてゆっくり動くため、操作性に優れ、高級感が得られる。勿論、このダンパ８による制動は、リンク３及びボタン２がばね部材Ｓ１の付勢力に抗して押圧操作するときも同様に働く。 (3) By the way, in this structure, when the pressure on the button 2 is released, the link 3 and the button 2 are raised to the original state by the urging force of the spring member S1. In this ascending process, the moving speed of the button 2 is braked by the damper 8 (engagement of the rack 26 of the link and the gear 8b) to move slowly, so that the operability is excellent and a high-class feeling can be obtained. Of course, the braking by the damper 8 also works when the link 3 and the button 2 press against the urging force of the spring member S1.

（４）、開閉体を開状態から再び閉状態にする場合、通常は、ロッド４Ａ，４Ｂがハウジング１内から突出した状態であっても、ロッド先端部４１，４４が固定本体の取付部８０ないしは開閉体の取付部に当たりながら摺動する際に受ける応力により、ロッド４Ａ，４Ｂがばね部材Ｓ２，Ｓ３の付勢力に抗してハウジング１内へ没方向に動いて対応する係止穴８１に再び係合可能となる。 (4) When the opening / closing body is changed from the open state to the closed state again, normally, even if the rods 4A and 4B are in a state of protruding from the inside of the housing 1, the rod tip portions 41 and 44 are the mounting portions 80 of the fixed main body. Or, due to the stress received when sliding while hitting the mounting portion of the opening / closing body, the rods 4A and 4B move in the sinking direction into the housing 1 against the urging force of the spring members S2 and S3 to form the corresponding locking hole 81. It becomes engageable again.

（５）、図４はロック装置９として、キーシリンダ６をキー操作により９０度回転し、ロック解除状態からロック状態に切り換えてボタン２の押操作を規制した状態を示している。この構造では、キーシリンダ６が図３のロック解除状態において、２つのストッパ部６５のうち一方のストッパ部６５が当接面１７ｅに当接した状態で回り止めされ、かつ、可撓爪６７ａが２つの凹凸部１８ｂのうち突起部１７ｊに近い側の凹凸部１８ｂに嵌合されている。 (5), FIG. 4 shows a state in which the key cylinder 6 is rotated 90 degrees by a key operation as the lock device 9, the unlocked state is switched to the locked state, and the pressing operation of the button 2 is restricted. In this structure, in the unlocked state of FIG. 3, the key cylinder 6 is stopped in a state where one of the two stopper portions 65 is in contact with the contact surface 17e, and the flexible claw 67a is provided. It is fitted to the uneven portion 18b on the side closer to the protruding portion 17j of the two uneven portions 18b.

そして、この構造では、キーシリンダ６がキー操作により時計回りの方向に回転されてロック状態に至る直前に、可撓爪６７ａが突起部１７ｆに近い側の凹凸部１８ｂに沿って摺接するためクリック音を伴い、また、一方のストッパ部つまり揺動片６７に近い側のストッパ部６５が当接面１７ｄに当たって回り止めする。同時に、図４（ｃ）の揺動片６７と大きく離れている側のストッパ部６５が被係合部３８の下面と係合する。その結果、リンク３及びボタン２は被係合部３８がストッパ部６５に規制されて下降つまり可動不能となる。可撓爪３７ａは、ロック状態からロック解除状態に切り換える場合、ロック解除状態に至る直前に突起部１７ｊに近い側の凹凸部１８ｂに沿って摺接するため、クリック音を伴い、これにより節度感により使い勝手を向上できる。 Then, in this structure, just before the key cylinder 6 is rotated in the clockwise direction by the key operation and reaches the locked state, the flexible claw 67a is slidably contacted along the uneven portion 18b on the side close to the protrusion 17f, so that the click is made. It is accompanied by noise, and one of the stopper portions, that is, the stopper portion 65 on the side closer to the rocking piece 67, hits the contact surface 17d and stops rotating. At the same time, the stopper portion 65 on the side largely separated from the swing piece 67 in FIG. 4C engages with the lower surface of the engaged portion 38. As a result, the engaged portion 38 of the link 3 and the button 2 is restricted by the stopper portion 65 and is lowered, that is, immovable. When switching from the locked state to the unlocked state, the flexible claw 37a slides along the uneven portion 18b on the side close to the protrusion 17j immediately before reaching the unlocked state, so that a click sound is accompanied by a feeling of moderation. Usability can be improved.

（変形例）図１０は図１（ａ）に対応した図、図１１は図１０のロック解除状態からロック状態に切り換えた図、図１２は図６に対応した図、図１３は図８（ａ）に対応した図である。この変形例では、キーシリンダ６をキー操作により回転してロック状態にしたり、ロック解除状態に切り換える操作として、上記形態のキー操作の回転方向と逆向きにする場合に好適な一例である。この説明では、上記形態と同じ部材や部位に同一符号を付して重複説明を省き、変更点だけを詳述する。 (Modification example) FIG. 10 is a diagram corresponding to FIG. 1 (a), FIG. 11 is a diagram in which the unlocked state of FIG. 10 is switched to the locked state, FIG. 12 is a diagram corresponding to FIG. It is a figure corresponding to a). This modification is a suitable example in which the key cylinder 6 is rotated by a key operation to put it in a locked state or is switched to an unlocked state in the direction opposite to the rotation direction of the key operation in the above-described embodiment. In this description, the same members and parts as in the above embodiment are designated by the same reference numerals, duplicate explanations are omitted, and only the changes are described in detail.

まず、ハウジング１では、キーシリンダ配置部１５が次のように形状変更されている。変形例のキーシリンダ配置部１５は、図６と図１２の対比から分かるごとく形態例のものを左右反転した状態となっている。すなわち、この配置部１５は、上側段差部１６と、上側段差部１６の中央部を深く窪ませた略円筒状の内側段差部１７と、内側段差部１７の左右に設けられてカバーの各係止片７４を受け入れる穴１７ａ及び該穴１７ａ内に突設した係止爪１７ｂと、内側段差部１７の内周面に突設されたストッパ用突起部１７ｃ、１７ｊと有し、また、突起部１７ｃの周方向両端面であるストッパ用当接面１７ｄ，１７ｅと、突起部１７ｊの周方向で逆時計回りの端面であるストッパ用当接面１７ｋと、突起部１７ｃと間隔を保って設けられて突起部１７ｃと同じく上面にキーシリンダの本体６０を受け止める突起部１７ｆ、１７ｇと、内側段差部１７の底面中央部を浅く窪ませた回動部材受け面１８と、回動部材受け面１８に円弧状に貫通形成された一対の回動部材用嵌合穴１８ａと、内側段差部１７の底面にあって回動部材受け面１８の外周の一部分に沿って若干浅く形成された円弧状の摺接面１８ｃ及び摺接面１８ｃの両端である２箇所の凹凸部１８ｂとを有している。 First, in the housing 1, the shape of the key cylinder arranging portion 15 is changed as follows. As can be seen from the comparison between FIGS. 6 and 12, the key cylinder arranging portion 15 of the modified example is in a state of being left-right inverted. That is, the arrangement portion 15 is provided on the left and right sides of the upper step portion 16, the substantially cylindrical inner step portion 17 in which the central portion of the upper step portion 16 is deeply recessed, and the inner step portion 17, and each of the covers is engaged. It has a hole 17a for receiving the stop piece 74, a locking claw 17b projecting into the hole 17a, and stopper protrusions 17c and 17j projecting from the inner peripheral surface of the inner step portion 17, and also has a protrusion portion. The stopper contact surfaces 17d and 17e, which are both end faces in the circumferential direction of 17c, the stopper contact surfaces 17k, which are end faces counterclockwise in the circumferential direction of the protrusion 17j, and the protrusion 17c are provided at intervals. As with the protrusion 17c, the protrusions 17f and 17g that receive the main body 60 of the key cylinder on the upper surface, the rotating member receiving surface 18 in which the central portion of the bottom surface of the inner step portion 17 is shallowly recessed, and the rotating member receiving surface 18 A pair of fitting holes 18a for rotating members formed through the arc shape, and an arc-shaped sliding surface formed slightly shallower along a part of the outer periphery of the rotating member receiving surface 18 on the bottom surface of the inner step portion 17. It has two uneven portions 18b, which are both ends of the contact surface 18c and the sliding contact surface 18c.

変形例のキーシリンダ６は、形態例に比べて本体６０は同じであり、ストッパ部６５の形状が左右反転されている。すなわち、図９の回動部材６３では、２つのストッパ部６５のうち、弾性片６７と近い側のストッパ部６５が時計回りに位置している。これに対し、図１３の回動部材６３では、２つのストッパ部６５のうち、弾性片６７と近い側のストッパ部６５が逆時計回り方向に位置している点で変更されている。 The main body 60 of the key cylinder 6 of the modified example is the same as that of the morphological example, and the shape of the stopper portion 65 is reversed left and right. That is, in the rotating member 63 of FIG. 9, of the two stopper portions 65, the stopper portion 65 on the side closer to the elastic piece 67 is located clockwise. On the other hand, in the rotating member 63 of FIG. 13, of the two stopper portions 65, the stopper portion 65 on the side closer to the elastic piece 67 is located in the counterclockwise direction.

以上の変更により、この変形例では、例えば、キーシリンダ６が図１０のロック解除状態からキー操作により逆時計回りの方向に回転されて図１１のロック状態に至る直前に、可撓爪６７ａが突起部１７ｆに近い側の凹凸部１８ｂに沿って摺接するためクリック音を伴い、また、一方のストッパ部つまり揺動片６７に近い側のストッパ部６５が当接面１７ｄに当たって回り止めする。同時に、図１０（ｂ）の揺動片６７と大きく離れている側のストッパ部６５が被係合部３８の下面と係合する。その結果、リンク３及びボタン２は被係合部３８がストッパ部６５に規制されて下降ないしは可動不能となる。 Due to the above changes, in this modification, for example, just before the key cylinder 6 is rotated in the counterclockwise direction by a key operation from the unlocked state of FIG. 10 and reaches the locked state of FIG. 11, the flexible claw 67a is provided. Since it slides along the uneven portion 18b on the side close to the protrusion 17f, a click sound is accompanied, and one stopper portion, that is, the stopper portion 65 on the side close to the rocking piece 67 hits the contact surface 17d and stops rotating. At the same time, the stopper portion 65 on the side greatly separated from the swing piece 67 in FIG. 10B engages with the lower surface of the engaged portion 38. As a result, the engaged portion 38 of the link 3 and the button 2 is restricted by the stopper portion 65 and becomes lower or immovable.

なお、本発明のロック装置は、請求項１又は２で特定される構成を備えておればよく、細部は以上の説明を参考にして変更したり展開可能なものである。その一例として、回動部材をキーシリンダに一体に形成したり、ダンパを省略して簡略化することである。
