本発明の主たる課題は、付勢手段の付勢力を利用し、いわゆるワンタッチで自動的に施錠できると共に、施錠時、蓋体に取り付けられ差込部材を可能な限り施錠位置へと引き寄せ、かばん・ケース類の錠前に発生するがたつきを自動的に吸収して常に気密性、保持力を保ち、これにより、いわゆる「がたつき」が生じにくいかばん・ケース類の錠前を提供するものである。本発明の二次的な課題は、前記課題に加え、かばん・ケース類の蓋体を無理やり開けようとしたりするという人為的な操作（特に第三者による不正開錠）や、かばん・ケース類取扱い時の衝撃（振動）による不意の開錠に対して一層保持力を増強できるかばん・ケース類の錠前を提供するものである。 The main subject of the present invention is that the urging force of the urging means can be used to automatically lock the bag with a so-called one-touch operation, and at the time of locking, the insertion member attached to the lid is pulled to the locked position as much as possible, and the bag. It automatically absorbs the rattling that occurs in the locks of cases and always maintains airtightness and holding power, thereby providing locks for bags and cases that are less likely to cause so-called "rattling". .. In addition to the above-mentioned problems, the secondary problems of the present invention include artificial operations (particularly unauthorized unlocking by a third party) such as forcibly opening the lids of bags and cases, and bags and cases. It provides locks for bags and cases that can further enhance the holding force against unexpected unlocking due to impact (vibration) during handling.

さらに、本発明の付加的な課題は、かばん・ケース類の蓋体に複数のかばん・ケース類の錠前を左右に取り付けたときに発生する左右勝手の使いづらさ、そのために左右仕様のかばん・ケース類の錠前を別々に２種類の作製しなければならならないという製品点数、工数、管理、コストアップ等という無駄をなくし、一種類のかばん・ケース類の錠前で左右使いの双方を兼用することができるかばん・ケース類の錠前を提供するものである。なお、二次的な課題及び付加的な課題は、本発明の特定要件となった場合に主たる課題に加味されるものである。 Further, an additional problem of the present invention is the difficulty of left-right hand-handling that occurs when a plurality of bags / case locks are attached to the left and right sides of the bag / case lid, and therefore the left-right specification bag. Eliminate the waste of product points, manpower, management, cost increase, etc. that require two types of locks for cases to be manufactured separately, and use both left and right locks for one type of bag / case. It provides locks for bags and cases that can be used. In addition, the secondary problem and the additional problem are added to the main problem when it becomes a specific requirement of the present invention.

The member 19 is slidably fitted to an operation knob rotatably provided on the case cover 18 connected to the mounting base 11 or the mounting base 11, and the locking lever is urged by the urging means 14. It is characterized in that it is either a sliding movable body 19A or 19B having a pressing portion that operates against the above.

また係合解除用の操作部材１９Ａが取付け基台１１に摺動自在に嵌合すると共に、施錠レバー１３Ａを付勢手段１４の付勢力に抗して作動させる押圧部を有する摺動可動体１９Ａの場合には、前記押圧部２３は、前記取付け基台１１を左右勝手として使用することができるように施錠レバー１３Ａの中心軸２４を基準として上下の位置に略回転対称に設けられていることを特徴とする。 Further, the operating member 19A for disengagement is slidably fitted to the mounting base 11, and the sliding movable body 19A has a pressing portion for operating the locking lever 13A against the urging force of the urging means 14. In the case of, the pressing portion 23 is provided at a position substantially rotationally symmetrically in the vertical position with respect to the central axis 24 of the locking lever 13A so that the mounting base 11 can be used as a left-right hand. It is characterized by.

また施錠カムは、その略中央部に施錠カム用軸と遊嵌合する軸孔を有し、不正開錠時に係合片が後退方向に移動すると、前記施錠カムは前記軸孔を介して前記係合片と略同方向へ移動し、これにより、取付け基台側に設けられた係合部１１ｆに前記施錠カムの第２係合部１２ｅが食い込むように当たることを特徴とする。 Further, the locking cam has a shaft hole loosely fitted with the locking cam shaft at a substantially central portion thereof, and when the engaging piece moves in the retracting direction at the time of unauthorized unlocking, the locking cam moves through the shaft hole. It moves in substantially the same direction as the engaging piece, whereby the second engaging portion 12e of the locking cam bites into the engaging portion 11f provided on the mounting base side.

また錠前本体は、ケースカバー１８の内側に係合解除用の操作部材と共働すると共に、施錠カムを係合解除の方向へと位置変位させる作動カム１６を有し、差込部材の進入により該差込部材の係合片１０２に設けた係合突起１０３が、前記施錠カムの第１係合部１２ｂと係合し、施錠カムが回動する際、施錠カムと共働して作動カムが回動するように構成し、一方、前記係合解除用の操作部材の操作力により、前記施錠カムと施錠レバーの連係部が施錠カム用軸１２ａを基準として位置変位し、これにより施錠カムと差込部材との解除が、前記係合解除用の操作部材の左右のいずれの回転方向によってもできるように構成したことを特徴とする。 Further, the lock body has an operating cam 16 inside the case cover 18 that cooperates with an operating member for disengaging and displaces the locking cam in the disengaging direction, and the insertion of the insertion member causes the locking cam to move. The engaging protrusion 103 provided on the engaging piece 102 of the insertion member engages with the first engaging portion 12b of the locking cam, and when the locking cam rotates, it cooperates with the locking cam to operate the cam. On the other hand, due to the operating force of the operating member for disengagement, the coupling portion between the locking cam and the locking lever is displaced with respect to the locking cam shaft 12a, whereby the locking cam is displaced. It is characterized in that the insertion member and the insertion member can be disengaged in any of the left and right rotation directions of the disengagement operating member.

さらに、錠前本体は施錠カムと施錠レバーとを有し、前記施錠カムには、前記施錠レバーの一方の端部が施錠カムを上方に回動させるように取り付けられており、かつ施錠レバーの他方の端部は錠前本体の係合解除用の操作部材と連動させるように取り付けられており、施錠カムと差込部材との解除が、施錠レバーとの連動により、係合解除用の操作部材の下方への移動によってできるように構成したことを特徴とする。 Further, the lock body has a locking cam and a locking lever, and one end of the locking lever is attached to the locking cam so as to rotate the locking cam upward, and the other of the locking levers.

It is characterized by being configured so that it can be moved downward.

加えて、付勢手段１４は、クリック機能を有する付勢バネであり、この付勢バネの付勢力は、施錠カムと施錠レバーの連係部１２ｄ、１３ｄが施錠カム用軸１２ａを基準として上方に位置変位した場合には施錠方向に作用し、一方、前記連係部が施錠カム用軸１２ａを基準として下方に位置変位した場合には開錠方向に作用することを特徴とする。 In addition, the urging means 14 is an urging spring having a click function, and the urging force of the urging spring is such that the linking portions 12d and 13d of the locking cam and the locking lever move upward with reference to the locking cam shaft 12a. When the position is displaced, it acts in the locking direction, while when the linking portion is displaced downward with respect to the locking cam shaft 12a, it acts in the unlocking direction.

ここで「取付け基台側に設けられた係合部」は、取付け基台１１の周壁の一部１１ｆや取付け基台内に固定的に設けられた施錠用カバー１５のストッパー、その他のストッパーを言うもので、位置変位する施錠カム１２を所定位置で受け止める機能を有するストッパー部位やストッパー部材である。 Here, the "engagement portion provided on the mounting base side" includes a part 11f of the peripheral wall of the mounting base 11, a stopper of the locking cover 15 fixedly provided in the mounting base 11, and other stoppers. This is a stopper portion or a stopper member having a function of receiving the locking cam 12 whose position is displaced at a predetermined position.

独立請求項に記載の本発明は、従来のかばん・ケース類に取付けられるかばん・ケース類の錠前においては、かばん・ケース類の錠前の取付け位置の僅かなずれ、または使用中に発生するかばん・ケース類の錠前の緩みにより、または取扱い中の衝撃等により蓋体のがたつきが発生し、かばん・ケース類の錠前の施錠維持性、筐体と蓋体との施錠時の気密性、保持力を損なうことがあったが、このような欠点を解消することができる。すなわち、付勢手段の付勢力を利用し、いわゆるワンタッチで自動的に施錠できると共に、施錠時、蓋体に取り付けられ差込部材を可能な限り施錠位置へと引き寄せ、かばん・ケース類の錠前に発生するがたつきを自動的に吸収して常に気密性、保持力を保ち、これにより、いわゆる「がたつき」が生じにくいかばん・ケース類の錠前を提供することができる。 The present invention described in the independent claim states that, in the case of a conventional bag, a bag attached to a case, or a lock of a case, the attachment position of the lock of the bag or the case is slightly displaced, or a bag generated during use. Loosening of the locks of the cases or impact during handling causes rattling of the lid, which keeps the locks of the bags and cases locked, and keeps the housing and lid airtight when locked. Although it sometimes impaired power, such a defect can be eliminated. That is, by using the urging force of the urging means, it can be automatically locked with a so-called one-touch, and at the time of locking, it is attached to the lid and the insertion member is pulled to the locking position as much as possible to lock the bag / case. It is possible to provide locks for bags and cases that are less likely to cause so-called "rattling" by automatically absorbing the rattling that occurs and always maintaining airtightness and holding power.

また請求項２に記載の発明は、施錠状態時、例えば不正開錠操作により差込部材１００が退出方向に移動したとき、錠前本体１０の取付け基台側に設けられた係合部１１ｆに施錠カムの第２係合部一部１２ｅが食い込むように当たり、これにより前記施錠状態を保持することができる。さらに、実施形態如何によっては、サムターン式操作つまみ、スライド式可動体等の係合解除用の操作部材を左右のどちらに廻しても、或いは左右方向のいずれにスライドさせても開錠（係合解除）操作ができる。 The invention according to claim 2 locks the engaging portion 11f provided on the mounting base side of the lock body 10 when the insertion member 100 moves in the exit direction due to an unauthorized unlocking operation, for example, in the locked state. The second engaging portion 12e of the cam hits so as to bite into it, whereby the locked state can be maintained. Further, depending on the embodiment, the operation member for disengagement such as the thumb-turn type operation knob and the slide type movable body can be unlocked (engaged) by turning it to the left or right or sliding it in the left or right direction. Can be operated.

また実施形態如何によっては、操作つまみ、操作カバー等のスライド式可動体を下方に移動しても開錠操作ができるので、非常に使い勝手が良いという利点がある。また従来においては、右回転開錠用と左回転開錠用の２種類のかばん・ケース類の錠前を別々に用意しなければならないという状況も生じ、その場合、右用と左用の２種類のかばん・ケース類の錠前を別々に作製するという必要が生じ、製品点数の増加、コストアップの要因となっていたが、本発明の一実施態様によれば、右回転開錠用と左回転開錠用の２種類のかばん・ケース類の錠前を別々に作製することなく、一種類で共用できるという効果もあるので、製品点数の削減、コスト低減に繋がる等の付随的果的がある。 Further, depending on the embodiment, the unlocking operation can be performed even if the sliding movable body such as the operation knob and the operation cover is moved downward, so that there is an advantage that it is very convenient. In addition, in the past, there was a situation in which two types of locks for right-handed and left-handed unlocking and cases had to be prepared separately. In that case, two types of locks, one for right and one for left, had to be prepared. It has become necessary to separately manufacture locks for bags and cases, which has been a factor in increasing the number of products and increasing costs. However, according to one embodiment of the present invention, right-handed locks and left-handed locks are opened. Since there is an effect that one type of lock can be shared without separately producing two types of locks for locks and cases, there are incidental effects such as reduction in the number of products and cost reduction.

As described above, the thumb-turn type operating member 19 is attached to the case cover 18, and the operating member 19 and the operating cam 16 are attached so that the operating cam 16 can rotate, and is used for disengagement. The lock 1 can be unlocked (disengaged) via the locking lever 13 interlocked with the operating cam 16 by the operating force of the operating member 19.

ここで、本発明の主たる課題である「錠前の施錠の確実性」に関する引き寄せ機構について、図６を参照して説明する。図６（Ａ）に示すように、差込部材１００が筐体Ｂに向かって進入し、錠前本体の嵌合部位となる位置に向かうと、差込部材１００の係合片１０２の係合突起１０３が当該係合突起１０３に対応して設けられた施錠カム１２の切欠状被係合部（第１係合部）１２ｂと係合し、差込部材の進入（同図においては下方への移動）に応じて施錠カム１２は矢印Ｅ方向に回転する、これに対応して、施錠レバー１３は、その上端部の指先状連係部１３ｄが施錠カム１２の偏心位置にある軸状連係部１２ｄに連結されていることから、施錠カム用軸１２ａよりも上方へと位置変位する。この時、付勢手段１４の付勢力が「係合解除（開錠）方向」から「係合（施錠）方向」へと切り替わる。そこで、図６（Ｂ）に示すよう、施錠カム１２が施錠方向（矢印Ｅ方向）に回転中、さらに、図６（Ｃ）に示すように、更なる差込部材１００の係合片１０２が進入すると、つまり、付勢手段１４の付勢力により、施錠カム１２がＥ方向に回動し続けると、前記施錠カムは前記係合片１０２を施錠位置へと引き寄せるように自動的に回動して施錠状態となる。 Here, a pulling mechanism relating to "reliability of locking of a lock", which is a main subject of the present invention, will be described with reference to FIG. As shown in FIG. 6A, when the insertion member 100 enters toward the housing B and heads toward the position where the lock body is fitted, the engagement protrusion of the engagement piece 102 of the insertion member 100 The 103 engages with the notch-shaped engaged portion (first engaging portion) 12b of the locking cam 12 provided corresponding to the engaging protrusion 103, and the insertion member enters (in the figure, downward). The locking cam 12 rotates in the direction of arrow E in response to the movement). Since it is connected to the lock cam shaft 12a, the position is displaced upward from the locking cam shaft 12a. At this time, the urging force of the urging means 14 is switched from the “disengagement (unlocking) direction” to the “engagement (locking) direction”. Therefore, as shown in FIG. 6 (B), the locking cam 12 is rotating in the locking direction (direction of arrow E), and further, as shown in FIG. 6 (C), the engaging piece 102 of the further insertion member 100 is Upon entering, that is, when the locking cam 12 continues to rotate in the E direction due to the urging force of the urging means 14, the locking cam automatically rotates so as to pull the engaging piece 102 to the locking position. It becomes locked.

次に、本発明の二次的な課題である「施錠保持力の強化」について、図７（Ａ）、（Ｂ）を参照にして説明する。この態様における施錠カム１２においては、その軸孔１２ｃが楕円状の長孔とされている。すなわち、同図に示した様に、施錠カム１２の軸孔１２ｃは、差込部材１００の係合突起１０３の進入方向に長軸を持つ楕円形状となっており、取付け基台１１に設けられた施錠カム用軸１２ａが前記軸孔１２ｃ内を遊嵌するように、すなわち、施錠カム１２は、図７に示したように上下移動可能となるように軸支されている。したがって、施錠状態時、不正開錠操作により前記差込部材１００が退出方向に移動したとき、取付け基台側に設けられた係合部一部１１ｆに施錠カム１２の第２係合部１２ｅが食い込むように当たり、これにより前記施錠状態を保持することができる。 Next, "strengthening the locking and holding power", which is a secondary problem of the present invention, will be described with reference to FIGS. 7 (A) and 7 (B). In the locking cam 12 in this embodiment, the shaft hole 12c is an elliptical elongated hole. That is, as shown in the figure, the shaft hole 12c of the locking cam 12 has an elliptical shape having a long axis in the approach direction of the engaging projection 103 of the insertion member 100, and is provided on the mounting base 11. The locking cam shaft 12a is pivotally supported so as to be loosely fitted in the shaft hole 12c, that is, the locking cam 12 can be moved up and down as shown in FIG. Therefore, in the locked state, when the insertion member 100 moves in the exit direction due to an unauthorized unlocking operation, the second engaging portion 12e of the locking cam 12 is attached to the engaging portion 11f provided on the mounting base side. It hits so as to bite into it, whereby the locked state can be maintained.

さらに付言すると、差込部材１００の係合突起１０３が差込まれて進入し、施錠された初期の第１の状態においては、図７（Ａ）に図示したように、取付け基台１１の係合部１１ｆと施錠カム１２の第２係合部１２ｅとは若干の間隔ｍをもって離れた状態であって、施錠カム用軸１２ａは、楕円形状の軸孔１２ｃの上方の円周部に当接された状態となって保持され、施錠状態に維持される。一方、「がたつき」が生じて施錠状態の差込部材１００が、図７（Ｂ）において上方（Ｆ方向）に変動した場合、つまり、係合片１０２が上方に退出した時には、係合突起１０３が第１係合部１２ｂを形成する横向き凹所状の上方内壁面に押し上げるように当たるので、図７（Ｂ）に図示したように、その変動に応じて施錠カム１２は縦方向の楕円形状の軸孔１２ｃを介して上方に若干移動し、楕円形状の軸孔１２ｃの下方の円周部に当接された状態となって保持され、これにより取付け基台の施錠カムとの係合部１１ｆと施錠カムの取付け基台との第２係合部１２ｅとは係合し、両係合部１１ｆ、１２ｅとの間で、いわば楔のように抵抗力がかかった状態となる。
それ故に、施錠カム１２の施錠カム用軸１２ａの楕円形状の軸孔１２ｃ内の上方への移動、および抵抗力がかかった状態の取付け基台の施錠カムとの係合部１１ｆと施錠カムの取付け基台との第２係合部１２ｅとは係合の抵抗力の増大により、両方の係合部の保持力が強化され、これにより施錠力が強化される。 Further, in the initial first state in which the engaging projection 103 of the insertion member 100 is inserted and entered and locked, as shown in FIG. 7A, the mounting base 11 is engaged. The joint portion 11f and the second engaging portion 12e of the locking cam 12 are separated from each other with a slight distance m, and the locking cam shaft 12a abuts on the circumferential portion above the elliptical shaft hole 12c. It is held in a locked state and maintained in a locked state. On the other hand, when "rattling" occurs and the locked insertion member 100 fluctuates upward (F direction) in FIG. 7B, that is, when the engaging piece 102 retracts upward, the engaging member 100 engages. Since the protrusion 103 hits the laterally concave upper inner wall surface forming the first engaging portion 12b so as to push it up, as shown in FIG. 7B, the locking cam 12 is elliptical in the vertical direction according to the fluctuation. It moves slightly upward through the shaped shaft hole 12c and is held in contact with the lower circumferential portion of the elliptical shaft hole 12c, whereby it engages with the locking cam of the mounting base. The second engaging portion 12e of the portion 11f and the mounting base of the locking cam is engaged with each other, and a resistance force is applied between the engaging portions 11f and 12e like a wedge.
Therefore, the locking cam shaft 12a of the locking cam 12 moves upward in the elliptical shaft hole 12c, and the engaging portion 11f of the locking cam with the locking cam of the mounting base in a state where resistance is applied and the locking cam By increasing the resistance of engagement with the second engaging portion 12e with the mounting base, the holding force of both engaging portions is strengthened, whereby the locking force is strengthened.

好ましい態様においては、図７に示したように、施錠カムの軸孔１２ｃの長孔内における施錠カム用軸１２ａとの隙間の間隔ｎが、取付け基台の施錠カムの係止部１１ａと、施錠カムの所定の初期設定位置に軸支された際の係止部１２ｅとの間隔ｍがより大とされ、施錠カム用軸１２ａが前記楕円状の長孔の軸孔１２ｃ内において遊嵌され、施錠カム用軸１２ａが差込部材の進入方向と反対方向に移動した際、施錠カムの取付け基台との係合部１２ｄと、錠前本体の取付け基台の係合部１１ｆとが係合し、施錠の保持力が高められるようにされている。 In a preferred embodiment, as shown in FIG. 7, the gap n between the locking cam shaft 12a and the locking cam shaft 12a in the elongated hole of the locking cam shaft hole 12c is set between the locking cam locking portion 11a of the mounting base and the locking cam. The distance m from the locking portion 12e when the locking cam is pivotally supported at a predetermined initial setting position is made larger, and the locking cam shaft 12a is loosely fitted in the shaft hole 12c of the elliptical elongated hole. When the locking cam shaft 12a moves in the direction opposite to the entry direction of the insertion member, the engaging portion 12d with the locking cam mounting base and the engaging portion 11f of the locking cam mounting base engage with each other. However, the holding power of the lock is enhanced.

次に、図８は錠前１の開錠（係合解除）の動作を示した図面である。より正確には、図８の（Ａ）は、本発明の一実施態様の錠前の施錠状態を示す一部省略概略正面図であり、差込部材１００が進入して（図においては下降して）、施錠カム１２の第１係合部１２ｂと差込部材の係合突起１０３とが係合して施錠状態に達した状態を示す図面であり、施錠状態において、施錠レバー１３の上端方向の先端部に設けられた連係部１３ｄの位置に施錠用ばね１４の施錠レバーとのバネ端部（当接部）１４ａが達し、この部分において施錠用ばね１４の付勢力によって、施錠レバー１３の位置が保持され、施錠状態が維持されている。 Next, FIG. 8 is a drawing showing the operation of unlocking (disengaging) the lock 1. More precisely, FIG. 8A is a partially omitted schematic front view showing the locked state of the lock according to the embodiment of the present invention, in which the insertion member 100 has entered (lowered in the figure). ), The drawing shows a state in which the first engaging portion 12b of the locking cam 12 and the engaging projection 103 of the insertion member are engaged to reach the locked state, and in the locked state, in the upper end direction of the locking lever 13. The spring end portion (contact portion) 14a of the locking spring 14 with the locking lever reaches the position of the linking portion 13d provided at the tip portion, and the position of the locking lever 13 is reached by the urging force of the locking spring 14 at this portion. Is retained and the locked state is maintained.

上記の施錠状態から開錠するために、係合解除用の操作部材１９を図８（Ｂ）の様にＨ方向（すなわち右回り方向）に回すと、該操作部材の回す方向に応じて作動カム１６が右方向に回動し、作動カム１６の回動と連動して施錠レバー１３が下方に移動し、この動きに応じて施錠カム１２がＨ方向と同方向に回動し、施錠カムの第１係合部１２ｂが上方に位置するようになり、差込部材の係合突起１０３と施錠カムの第１係合部１２ｂとの係合が外れ、開錠状態となる。 When the operating member 19 for disengagement is turned in the H direction (that is, in the clockwise direction) as shown in FIG. 8B in order to unlock from the above locked state, it operates according to the turning direction of the operating member. The cam 16 rotates to the right, the locking lever 13 moves downward in conjunction with the rotation of the operating cam 16, and the locking cam 12 rotates in the same direction as the H direction in response to this movement, and the locking cam The first engaging portion 12b of the above is positioned above, and the engaging projection 103 of the insertion member and the first engaging portion 12b of the locking cam are disengaged, and the unlocked state is established.

一方、操作部材１９を図８の（Ｃ）の様にＩ方向（すなわち左回り方向）に回すと、係合解除用の操作部材の回す方向に応じて作動カム１６が左方向に回動し、作動カム１６の回動と連動して施錠レバー１３が下方に移動し、この動きに応じて施錠カム１２がＩ方向と反対方向に回動し、施錠カムの切欠状被係合部１２ｂが上方に位置するようになり、差込部材の係合突起１０３と施錠カムの切欠状被係合部１２ｂとの係合が外れ、開錠状態となる。 On the other hand, when the operating member 19 is turned in the I direction (that is, in the counterclockwise direction) as shown in FIG. 8C, the operating cam 16 rotates counterclockwise according to the turning direction of the operating member for disengagement. , The locking lever 13 moves downward in conjunction with the rotation of the operating cam 16, the locking cam 12 rotates in the direction opposite to the I direction in response to this movement, and the notched engaged portion 12b of the locking cam It will be located above, and the engaging protrusion 103 of the insertion member will be disengaged from the notched engaged portion 12b of the locking cam, and the unlocked state will be established.

以上のように、この実施態様の錠前１によれば、係合解除用の操作部材１９を右方向に廻しても、左方向に廻しても、どちらの方向に廻しても同様に開錠を行なうことができ、一種類で左右共用できる。すなわち、右用、左用の２種類の商品を作る必要がなくなる。 As described above, according to the lock 1 of this embodiment, the unlocking is performed in the same manner regardless of whether the operating member 19 for disengagement is turned to the right, to the left, or in either direction. It can be done, and one type can be shared on the left and right. That is, it is not necessary to make two types of products, one for the right and one for the left.

この欄では、本発明の第２実施形態及び第３実施形態を説明する（同一の構成部分には同一・同様の符号を付して重複する説明を割愛する）。 In this column, the second embodiment and the third embodiment of the present invention will be described (the same components are designated by the same or similar reference numerals and duplicated description will be omitted).

まず、図９乃至図１１は、本発明の第２実施形態を示す各説明図である。この第２実施形態が第１実施形態と主に異なる点は、操作部材１９Ａと施錠レバー１３Ａである。図９は、図３と同様の内部構造の概略説明図、図１０は図４と同様の主要部と共に操作部材を含む分解説明図、図１１は図８と同様の各概略説明図で、（Ａ）は施錠状態の一例、（Ｂ）はケース状カバーに相当する操作部材１９Ａを（Ａ）を基準として左方向（符号Ｋ方向）に移動させた一例、は前記操作部材１９Ａを（Ａ）を基準として右方向（符号Ｌ方向）に移動させた一例をそれぞれ示す。 First, FIGS. 9 to 11 are explanatory views showing a second embodiment of the present invention. The main difference between this second embodiment and the first embodiment is the operating member 19A and the locking lever 13A. 9 is a schematic explanatory view of the internal structure similar to that of FIG. 3, FIG. 10 is an exploded explanatory view including an operation member together with a main part similar to that of FIG. 4, and FIG. 11 is a schematic explanatory view similar to that of FIG. A) is an example of the locked state, (B) is an example of moving the operating member 19A corresponding to the case-shaped cover in the left direction (reference numeral K direction) with reference to (A), and (A) is the operating member 19A. Is shown as an example of moving to the right (reference numeral L direction) with reference to.

さて、好ましい操作部材の一例として、ケースカバー１８に外嵌合する操作カバー１９Ａを、左右の横方向のどちらに押しても開錠できるようにした第２実施態様について簡単に説明する。例えば図９は、その側壁が略矩形形状のケースカバー１８を正面図から見た概略説明図である。このケースカバー１８の外壁面に摺接するようにその側壁が略矩形形状の操作カバー１９Ａが手前側に外嵌合している。 By the way, as an example of a preferable operation member, a second embodiment in which the operation cover 19A externally fitted to the case cover 18 can be unlocked by pushing it in either the left or right lateral direction will be briefly described. For example, FIG. 9 is a schematic explanatory view of a case cover 18 whose side wall has a substantially rectangular shape as viewed from the front view. An operation cover 19A whose side wall has a substantially rectangular shape is externally fitted to the front side so as to be in sliding contact with the outer wall surface of the case cover 18.

この図９を基準にすると、ケースカバー１８の上方に位置するのが施錠カム１２、この施錠カム１２に上端部側の連係部１３ｄが位置するように中心軸としての支軸２４を介して傾倒状に配設されているのが棒状の施錠レバー１３Ａ、前記支軸（中心軸）２４を基準として前記棒状の施錠レバー１３Ａの下杆部分の左側壁に当接或いは接近しているのが第１押圧部２２としてのボス（突起部）、一方、前記支軸（中心軸）２４を基準として前記棒状の施錠レバー１３Ａの上杆部分の右側壁に当接或いは接近しているのが第２押圧部２２としてのボス（突起部）である。 Based on FIG. 9, the locking cam 12 is located above the case cover 18, and the locking cam 12 is tilted via the support shaft 24 as the central axis so that the linking portion 13d on the upper end side is located on the locking cam 12. The rod-shaped locking lever 13A is arranged in a shape, and the rod-shaped locking lever 13A is in contact with or close to the left side wall of the lower rod portion of the rod-shaped locking lever 13A with reference to the support shaft (central shaft) 24. 1 The boss (protrusion) as the pressing portion 22, while the second is in contact with or close to the right wall of the upper rod portion of the rod-shaped locking lever 13A with reference to the support shaft (central shaft) 24. It is a boss (protrusion portion) as the pressing portion 22.

このように、第２実施形態の操作部材１９Ａは、取付け基台１１或いはケースカバー１８に比して左右方向に大きく形成され、かつ、前記取付け基台１１或いはケースカバー１８に摺動自在に嵌合すると共に、施錠レバー１３Ａを右側に配設された付勢手段１４の付勢力に抗して作動させる単数又は複数（この実施形態）の押圧部２２を有する摺動可動体である。なお、符号１２ｆは施錠カム１２の第１係合部１２ｂとは反対側の部位に突設したバネ端支持部で、このバネ端支持部１２ｆは施錠カムの一部に相当するもので、付勢手段１４の一方側のバネ端部が圧接する。 As described above, the operating member 19A of the second embodiment is formed larger in the left-right direction than the mounting base 11 or the case cover 18, and is slidably fitted to the mounting base 11 or the case cover 18. It is a sliding movable body having one or a plurality of pressing portions 22 (in this embodiment) which are combined and actuated against the urging force of the urging means 14 arranged on the right side of the locking lever 13A. Reference numeral 12f is a spring end support portion projecting from a portion of the locking cam 12 opposite to the first engaging portion 12b, and this spring end support portion 12f corresponds to a part of the locking cam and is attached. The spring end on one side of the force means 14 is in pressure contact.

この第２実施形態の好ましい例は、前記一対の押圧部２２、２２は、左右方向にスライド可能な摺動可動体１９Ａを、固定部材であるケースカバー１８に対して右又は左方向にいずれにスライドさせても、摺動可動体１９Ａに連動する摺動式施錠レバー１３Ａの中心軸２４を基準として上下の位置に略回転対称に設けられている。 In a preferred example of the second embodiment, the pair of pressing portions 22, 22 has a sliding movable body 19A slidable in the left-right direction in either the right or left direction with respect to the case cover 18 which is a fixing member. Even if it is slid, it is provided substantially rotationally symmetrically at the upper and lower positions with reference to the central axis 24 of the sliding locking lever 13A that is interlocked with the sliding movable body 19A.

上記構成により、本発明の付随的課題である「かばん・ケース類の蓋体に複数のかばん・ケース類の錠前を左右に取り付けたときに発生する左右勝手の使いづらさを解消する」。であるから左右仕様のかばん・ケース類の錠前を別々に２種類の作製しなければならならないという製品点数、工数、管理、コストアップ等という無駄をなくし、一種類のかばん・ケース類の錠前で左右使いの双方を兼用することができるかばん・ケース類の錠前を提供するということを達成することができる。 The above configuration eliminates the difficulty of left-right hand-handling that occurs when a plurality of bag / case locks are attached to the left and right sides of the lid of the bag / case, which is an incidental problem of the present invention. Therefore, it eliminates the waste of product points, man-hours, management, cost increase, etc., which requires the production of two types of locks for left and right bags and cases separately, and uses one type of locks for bags and cases. It is possible to achieve the provision of locks for bags and cases that can be used for both left and right use.

ここで、図１１の（Ａ）、（Ｂ）及び（Ｃ）を参照にして、左右引きの開錠動作についてさらに付言する。図１１に於いて、１００は差込み部材、１０は錠前本体、１２は施錠カム、１３Ａは中心軸としての支軸２４に左右方向に回動自在に軸支された施錠レバーである。 Here, with reference to FIGS. 11 (A), (B), and (C), the unlocking operation of the left-right pull is further added. In FIG. 11, 100 is an insertion member, 10 is a lock body, 12 is a lock cam, and 13A is a lock lever rotatably supported in the left-right direction on a support shaft 24 as a central axis.

前述したように施錠レバー１３Ａの上端部は、施錠カム１２の施錠用取付け用軸１２ｄに軸支され、施錠レバー１３Ａの動きに応じて施錠カム１２を回動できるようになっている。２２は上下一対の押圧部で、これらの押圧部２２、２２はケース状操作部材（例えば操作カバー）１９Ａの内壁面に固定的に設けられている。 As described above, the upper end of the locking lever 13A is pivotally supported by the locking mounting shaft 12d of the locking cam 12, and the locking cam 12 can be rotated according to the movement of the locking lever 13A. Reference numeral 22 denotes a pair of upper and lower pressing portions, and these pressing portions 22 and 22 are fixedly provided on the inner wall surface of the case-shaped operating member (for example, the operating cover) 19A.

そこで、図１１（Ａ）は、差込部材１００が進入して（図においては下降して）、施錠カム１２の切欠状被係合部１２ｂと差込部材の係合突起１０３が係合し、施錠レバー１３Ａにて両者の係合が維持されている施錠状態を示す。この施錠状態において、操作カバーである係合解除用の操作部材１９Ａを図１１の（Ｂ）の様に、Ｋ方向（すなわち左方向）に動かすと、該操作部材１９Ａの移動に伴って上方の第２のボス２２が施錠レバー１３ＡをＫ方向に押して、施錠レバー１３Ａが支軸２４を支点として左方向（反時計方向）に旋回し、この施錠レバー１３Ａの移動方向に応じて施錠カム１２が右上方向（時計方向）に回動し、これにより施錠カム１２の切欠状被係合部１２ｂが上方に位置するようになり、差込部材の係合突起１０３と施錠カムの切欠状被係合部１２ｂとの係合が外れ、開錠状態となる。 Therefore, in FIG. 11A, the insertion member 100 enters (descends in the drawing), and the notch-shaped engaged portion 12b of the locking cam 12 and the engagement projection 103 of the insertion member engage with each other. , Indicates a locked state in which the engagement between the two is maintained by the locking lever 13A. In this locked state, when the operating member 19A for disengagement, which is the operating cover, is moved in the K direction (that is, to the left) as shown in FIG. 11B, the operating member 19A moves upward as the operating member 19A moves. The second boss 22 pushes the locking lever 13A in the K direction, the locking lever 13A turns to the left (counterclockwise) with the support shaft 24 as a fulcrum, and the locking cam 12 moves according to the moving direction of the locking lever 13A. It rotates in the upper right direction (clockwise), so that the notch-shaped engaged portion 12b of the locking cam 12 is positioned upward, and the engaging protrusion 103 of the insertion member and the notch-shaped engaged portion of the locking cam are engaged. The engagement with the portion 12b is disengaged, and the lock is released.

一方、図１１の（Ｃ）の様に、Ｌ方向（すなわち右方向）に動かすと、操作部材１９Ａの移動に伴って下方の第１押圧部２２が施錠レバー１３ＡをＬ方向と反対方向に押して施錠レバー１３Ａが支軸２４を支点として左方向（反時計方向）に旋回し、施錠レバー１３Ａの移動方向に応じて施錠カム１２が右上方向（時計方向）に回動し、これにより施錠カム１２の切欠状被係合部１２ｂが上方に位置するようになり、差込部材の係合突起１０３と施錠カムの切欠状被係合部１２ｂとの係合が外れ、開錠状態となる。 On the other hand, when it is moved in the L direction (that is, to the right) as shown in FIG. 11C, the lower first pressing portion 22 pushes the locking lever 13A in the direction opposite to the L direction as the operating member 19A moves. The locking lever 13A turns to the left (counterclockwise) with the support shaft 24 as a fulcrum, and the locking cam 12 rotates in the upper right direction (clockwise) according to the moving direction of the locking lever 13A, whereby the locking cam 12 The notch-shaped engaged portion 12b is located above, and the engaging protrusion 103 of the insertion member is disengaged from the notched-shaped engaged portion 12b of the locking cam, and the unlocked state is established.

上記のように構成すると、係合解除用の操作部材１９Ａを左右の横方向のいずれの方向に押しても開錠を行なうことができ、左用、右用の２種類の商品を作ることなく、１種類で左右共用（左右勝手）することができる。 With the above configuration, the unlocking can be performed by pushing the operating member 19A for disengagement in either the left or right lateral direction, without making two types of products, one for the left and one for the right. Left and right can be shared by type (left and right).

次に、図１２及び図１３は、本発明の第３実施形態を示す各説明図である。この第３実施形態が第１実施形態と主に異なる点は、操作部材１９Ｂである。この第３実施形態も、第１実施形態と同様に錠前本体１０は、施錠カム１２と施錠レバー１３等とを有し、前記施錠カム１２には、前記施錠レバー１２の一方の端部が施錠カム１２を上方方向に回動させるように取り付けられており、かつ、該施錠レバーの他方の端部は錠前本体の係合解除用の操作部材１９Ｂの複数個の押圧部（係合部）２２、２２に連動させるように取り付けられている。 Next, FIGS. 12 and 13 are explanatory views showing a third embodiment of the present invention. The main difference between this third embodiment and the first embodiment is the operating member 19B. In this third embodiment as well, the lock body 10 has a locking cam 12, a locking lever 13 and the like, and the locking cam 12 is locked by one end of the locking lever 12. The cam 12 is attached so as to rotate upward, and the other end of the locking lever is a plurality of pressing portions (engaging portions) 22 of the operating member 19B for disengaging the lock body. , 22 are attached so as to be interlocked with each other.

そして、図１３（Ｂ）で示すように、施錠カム１２と差込部材１００との解除が、施錠レバー１３との連動により、係合解除用の操作部材１９Ｂの下方への移動によってできるように構成している。このように操作部材１９Ｂの形状、操作態様を適宜に設計変更しても、本発明の主たる課題を達成することができる。また本発明の二次的な発明の課題も達成することができる。 Then, as shown in FIG. 13B, the locking cam 12 and the insertion member 100 can be released by moving the operating member 19B for disengagement downward by interlocking with the locking lever 13. It is configured. Even if the shape and operation mode of the operation member 19B are appropriately redesigned in this way, the main problem of the present invention can be achieved. In addition, the problems of the secondary invention of the present invention can also be achieved.

なお、第２実施形態及び第３実施形態も、本発明の付加的な課題（錠前を左右勝手として使用すること）を達成するために、操作部材に連動する複数の押圧部２２．２２を適宜箇所に一対設けている。 In addition, also in the second embodiment and the third embodiment, in order to achieve the additional problem of the present invention (use of the lock as left and right hand), a plurality of pressing portions 22.22 interlocking with the operating member are appropriately provided. A pair is provided at each location.
