(A)-(e) of FIG. 11 is explanatory drawing for demonstrating the action | operation of the lock 3. FIG.

次いで、この錠前３の作動を図１１に基づいて説明する。   Next, the operation of the lock 3 will be described with reference to FIG.

図１１の（ａ）は、図７に対応するもので、錠前３が解錠状態にある。この状態から、前記かぶせプレート６の上縁６ａに手指を掛けてかぶせ側の錠前要素４を本体側の錠前要素５の挿入口５ａに向けて押し込むことにより図１１の（ｂ）及び同図の（ｃ）の状態を経て、同図の（ｄ）の施錠状態となる。すなわち、かぶせ側の錠前要素４を下方（矢印Ｘ方向）に移動させて本体側の錠前要素５に挿入し始めた段階で、図１１の（ｂ）に示すように、かぶせ側の錠前要素４の両フック２１の係合部２９が本体側の錠前要素５の側面側の壁部５５の上半部５５ａに接触する。この状態からかぶせ側の錠前要素４を下方（矢印Ｘ方向）に移動させて本体側の錠前要素５により深く挿入していくと、図１１の（ｃ）に示すように、前記壁部５５の上半部５５ａと前記係合部２９の傾斜案内縁２９ａとの相互案内作用により、前記両フック２１が相寄る方向（矢印α方向）に回動させられるようになる。そして、さらにかぶせ側の錠前要素４を下方（矢印Ｘ方向）に移動させると、図１１の（ｄ）に示すように、前記かぶせ側の錠前要素４のフック２１に設けられた係合部２９が前記本体側の錠前要素５のゲート３５を通過し終わることになり、前記側面側の壁部５５による拘束が解かれて前記両フック２１がねじりコイルばね２５の付勢力により一気に離間方向に回動することになり、これら両フック２１の係合部２９における係合縁２９ｂが前記ゲート３５の側面側の壁部５５の下縁５５ｂに係合して施錠状態となる。この施錠状態から図１１の（ｅ）に示すように、両操作部３１をつまんで両フック２１を相寄る方向（矢印β方向）に操作すると、前記両フック２１の係合部２９がゲート３５内に収まる位置に没入する。そのため、この操作状態を維持したままかぶせ側の錠前要素４を上方（矢印Ｙ方向）に抜き上げることにより、錠前３を解錠することができる。   FIG. 11A corresponds to FIG. 7, and the lock 3 is in the unlocked state. From this state, by placing a finger on the upper edge 6a of the cover plate 6 and pushing the lock element 4 on the cover side toward the insertion port 5a of the lock element 5 on the main body side, FIG. 11 (b) and FIG. After the state (c), the locked state shown in FIG. That is, when the cover-side lock element 4 is moved downward (in the direction of the arrow X) and started to be inserted into the lock element 5 on the main body side, as shown in FIG. The engaging portions 29 of both the hooks 21 come into contact with the upper half portion 55a of the wall portion 55 on the side surface side of the lock element 5 on the main body side. When the cover-side lock element 4 is moved downward (in the direction of the arrow X) from this state and inserted deeper into the lock element 5 on the main body side, as shown in FIG. Due to the mutual guiding action between the upper half portion 55a and the inclined guide edge 29a of the engaging portion 29, the hooks 21 can be rotated in the direction in which they come together (arrow α direction). When the cover side lock element 4 is further moved downward (in the direction of the arrow X), as shown in FIG. 11 (d), the engaging portion 29 provided on the hook 21 of the cover side lock element 4 is provided. Will end passing through the gate 35 of the lock element 5 on the main body side, the restraint by the wall portion 55 on the side surface side is released, and both the hooks 21 rotate in the separating direction at once by the urging force of the torsion coil spring 25. The engaging edge 29b of the engaging portion 29 of both the hooks 21 engages with the lower edge 55b of the wall portion 55 on the side surface side of the gate 35 to be locked. As shown in FIG. 11 (e) from this locked state, when both the operating portions 31 are pinched and operated in the direction in which both hooks 21 are brought together (arrow β direction), the engaging portions 29 of the both hooks 21 become the gate 35. Immerse into a position that fits inside. Therefore, the lock 3 can be unlocked by pulling the lock-up element 4 on the cover side upward (in the direction of arrow Y) while maintaining this operation state.

以上に述べた構成によれば、かぶせ２の内側にかぶせ側の錠前要素４を配したので、錠前３がランドセルＲの外面に大きく露出することを抑制することができ、外観をシンプルなものにすることができる。   According to the configuration described above, since the cover side lock element 4 is arranged inside the cover 2, it is possible to suppress the lock 3 from being greatly exposed to the outer surface of the school bag R, and to simplify the appearance. can do.

しかも、操作部３１をかぶせ側の錠前要素４の先端側に設けているので、かぶせ側の錠前要素４をかぶせ２の内面に設けても、操作性が損なわれることを防止又は抑制することができる。すなわち、操作部３１を錠前要素４、５同士の係合位置Ｋよりも先端側に位置させているので、錠前３の大部分を隠蔽した状態で操作部３１のみをかぶせ２の先端２ａ付近に配置することができる。そのため、外観のシンプルさを損ねることなしに、操作性を向上させることが可能となる。この実施形態では、操作部３１のみをかぶせ２の先端２ａよりも外方に突出させ、施錠状態で操作部３１以外の部分を隠蔽できるようにしているので、外観のシンプルさと操作性の良好さを両立させることができる。   Moreover, since the operation portion 31 is provided on the distal end side of the cover-side lock element 4, even if the cover-side lock element 4 is provided on the inner surface of the cover 2, it is possible to prevent or suppress the operability from being impaired. it can. That is, since the operation portion 31 is positioned on the tip side from the engagement position K between the lock elements 4 and 5, only the operation portion 31 is covered in the vicinity of the tip 2 a of the cover 2 in a state where most of the lock 3 is concealed. Can be arranged. Therefore, the operability can be improved without deteriorating the simplicity of the appearance. In this embodiment, since only the operation part 31 is covered and protrudes outward from the tip 2a of the cover 2 so that parts other than the operation part 31 can be concealed in the locked state, the appearance is simple and the operability is good. Can be made compatible.

さらに、従来のランドセルの多くは錠前がかぶせの外側かつランドセルの底面に配されていることが多く、このようなランドセルを使用者である児童が背負った状態では保護者から錠前が確認できず、保護者が解錠する場合手探りで錠前を探す必要があった。これに対し、本実施形態の構成では、ランドセルＲを児童が背負った状態でも錠前３の（特に操作部３１の）位置を保護者が視認できるので、ランドセルＲを児童が背負った状態で保護者が錠前３を解錠することができる。   In addition, many of the conventional school bags are often placed on the outside of the cover and on the bottom of the school bag, and in the state where the child who is the user carries such a school bag, the lock cannot be confirmed from the guardian, When guardians unlocked, they had to search for the lock by groping. On the other hand, in the configuration of the present embodiment, since the guardian can visually recognize the position of the lock 3 (particularly, the operation unit 31) even when the child is carrying the school bag R, the guardian can be viewed while the child is carrying the school bag R. Can unlock the lock 3.

また、操作部３１を錠前要素４、５同士の係合位置Ｋに対して先端側に所定距離ｄだけ離間させて配しているので、操作する指が係合部２９に触れる可能性を低減させることができ、安全性を向上させることもできる。   In addition, since the operation portion 31 is arranged at a distance of a predetermined distance d from the engagement position K between the lock elements 4 and 5 on the distal end side, the possibility that the operating finger touches the engagement portion 29 is reduced. It is possible to improve safety.

さらに、この実施形態では、対をなす操作部３１をつまむことにより係脱を操作し得るようにしているので、操作が簡単であり、その一方で、対をなす操作部３１をつままないと解錠できないようにしているので、外部からの作用により施錠状態が意図せず解除されることが起こりにくい。加えて、従来の錠前がかぶせの外側にあるランドセルでは、錠前が大きく露出しているため他の児童にいたずら等により解錠される恐れがあったが、本実施形態の構成では、錠前３は操作部３１の一部のみが露出しており、対をなす操作部３１をつままないと解錠できないようにしていることと併せて、いたずらで解錠される不具合の発生を抑制することもできる。   Further, in this embodiment, since the engagement / disengagement can be operated by pinching the paired operation units 31, it is easy to operate, while it is understood that the paired operation units 31 are not held. Since it cannot be locked, it is unlikely that the locked state is unintentionally released due to an external action. In addition, in the school bag where the conventional lock is on the outside of the cover, the lock is greatly exposed, so there is a risk that it will be unlocked by mischief etc. by other children, but in the configuration of this embodiment, the lock 3 is In addition to the fact that only a part of the operation unit 31 is exposed and cannot be unlocked unless the paired operation units 31 are held together, it is possible to suppress the occurrence of malfunctions that are unlocked by mischief. .

加えて、かぶせプレート６の上縁６ａを他の縁より厚くしているので、別途の指掛部材を設けることなく、かぶせプレート６の上縁６ａに指を掛けて容易に施錠操作を行うことができる。   In addition, since the upper edge 6a of the cover plate 6 is thicker than the other edges, it is possible to easily perform the locking operation by placing a finger on the upper edge 6a of the cover plate 6 without providing a separate finger hook member. Can do.

そして、本体側の錠前要素５における挿入口５ａを形成する壁部５３、５５を、挿入口５ａの開口面積が入口側に向かって漸次大きくなるよう傾斜させてあるので、かぶせ側の錠前要素４を本体側の錠前要素５に挿入しやすい。   And since the wall parts 53 and 55 which form the insertion port 5a in the lock element 5 on the main body side are inclined so that the opening area of the insertion port 5a gradually increases toward the inlet side, the lock element 4 on the cover side Can be easily inserted into the lock element 5 on the main body side.

なお、本発明は以上に述べた実施形態に限らない。   The present invention is not limited to the embodiment described above.

例えば、ランドセル以外のかばんに本発明を適用してもよい。   For example, the present invention may be applied to bags other than school bags.

また、かぶせは、真上からかばん本体にかぶせるものに限らず、例えば斜め上方からかばん本体に重なり合わせるようなものにする等、種々変形が可能である。   Further, the covering is not limited to the covering from the top to the bag main body, but can be variously modified, for example, by overlapping the bag main body from obliquely above.

一方、錠前は、かぶせ側の錠前要素と、本体側の錠前要素とを係脱させるようなものであれば、どのようなものであってもよく、その係脱を操作するための操作部も、どのようなものであってもよく、例えば、前述した実施形態のようにかぶせ側に設ける代わりに、本体側に設けてもよい。また、操作部自体の構造も、前述した実施形態のもの、すなわち対をなす操作部をつまむことにより係脱を操作し得るようにする構造のものの他に、ボタンを押圧する操作により係脱を操作し得るようにする構造等、他の構造を採用してもよい。   On the other hand, the lock may be anything as long as the lock element on the cover side and the lock element on the main body side are engaged and disengaged, and the operation unit for operating the engagement and disengagement is also provided. For example, instead of being provided on the covering side as in the above-described embodiment, it may be provided on the main body side. In addition to the structure of the above-described embodiment, that is, the structure in which the operation part itself can be operated by pinching a pair of operation parts, the operation part itself can be engaged and disengaged by pressing a button. Other structures, such as a structure that allows operation, may be employed.

また、前記実施形態では、操作部の一部をかぶせの先端より外側に突出させているが、操作部の全体をかぶせの先端よりも外側に突出させたり、操作部の全体をかぶせの先端部の内側に配したりしてもよい。これらのようなものであっても、操作部が先端側に設けられているため、操作性が損なわれるのを防止又は抑制することができる。   Further, in the above-described embodiment, a part of the operation unit protrudes outward from the tip of the cover. However, the entire operation unit protrudes outward from the tip of the cover, or the entire operation unit covers the tip. Or it may be placed inside. Even if it is such, since the operation part is provided in the front end side, it can prevent or suppress that operativity is impaired.

さらに、本発明には、かぶせプレート全体を指を掛けることができる程度に厚手のものにしたものも含まれているが、前記実施形態のように、前記かぶせプレートの上縁を他の縁よりも厚くしておけば、かぶせプレートを全体的には薄いものにしつつ、施錠の際の操作性を改善することができ、また、軽量化を図ることも可能となる。   Further, the present invention includes a cover plate that is thick enough to allow a finger to be hung, but the upper edge of the cover plate is different from the other edges as in the above embodiment. If the thickness of the cover plate is increased, the covering plate can be made thin as a whole, the operability at the time of locking can be improved, and the weight can be reduced.

そして、本発明には、本体側の錠前要素の挿入口を入口側に向かって漸次大きくしていないものも含まれるが、前記実施形態のように、前記挿入口を入口側に向かって漸次大きくしておけば、施錠動作を円滑に行うことができる。なお、挿入口を入口側に向かって漸次大きくする手段としては、前記実施形態のように、壁部の一部のみを傾斜させるものに限らず、壁部の全体を傾斜させるものであってもよい。   Further, the present invention includes those in which the insertion port of the lock element on the main body side is not gradually increased toward the inlet side, but the insertion port is gradually increased toward the inlet side as in the above embodiment. If this is done, the locking operation can be performed smoothly. Note that the means for gradually increasing the insertion port toward the inlet side is not limited to the one that inclines only a part of the wall part as in the above-described embodiment, and the part that inclines the entire wall part. Good.

加えて、本体側の錠前要素は、前記実施形態のように、前面側の壁部と、この前面側の壁部の両端に連続して設けられた側面側の壁部とを備えたゲートを有するものに限らず、例えば、図１２に示すような錠前要素Ａ５であってもよい。この錠前要素Ａ５は、前記実施形態の本体側の錠前要素５における前面側の壁部５３の中間部分をなくした形態をなすものである。なお、前記図１２において、前記実施形態と同一又は相当する部分には同一の符号を付して説明を省略する。   In addition, the lock element on the main body side includes a gate provided with a front wall portion and side wall portions provided continuously at both ends of the front wall portion as in the above embodiment. For example, a lock element A5 as shown in FIG. 12 may be used. The lock element A5 has a form in which an intermediate portion of the wall portion 53 on the front surface side in the lock element 5 on the main body side of the embodiment is eliminated. In FIG. 12, the same or corresponding parts as those in the embodiment are given the same reference numerals, and the description thereof is omitted.
