【考案の詳細な説明】
この考案は、主として牛乳受箱若しくは郵便箱のように
、箱の表裏にそれぞれ蓋を設けて、一方の入口から挿入
した物を他方の出口から取り出すようにして使用される
箱に関し、蓋の開閉動作によって自動的に表蓋が施錠さ

るようにした箱の蓋の施錠装置に関するものである。[Detailed description of the invention] This invention is mainly used in cases where a lid is provided on the front and back of the box, such as a milk box or a mail box, so that items inserted through one entrance can be taken out from the other exit. This invention relates to a locking device for a box lid, in which the front lid is automatically locked by the opening/closing operation of the lid, and the front lid is unlocked by the opening operation of the back lid.

い欠点があった。Conventional devices of this type have a swinging bottom plate on the bottom of the box body that locks the lower back of the top plate at the front end, and the swinging bottom plate changes the center of gravity by placing the object stored in the box in a predetermined position. Since it had a structure in which the front cover was locked by the operation of the bottom plate, there was a drawback that it could not be locked unless the contents were placed in a predetermined place.

装置を提供したものである。In this invention, a front cover and a back cover are attached to the front and back sides of the box body, which can be opened and closed freely with hinged upper edges, and a lever is provided that swings along the bottom side of the box body. A contact element is provided at the end of the lever that swings the lever in response to the opening operation of the camera back, while an elevating rod whose lower end is hinged is connected to the front end of the lever. A magnet that attracts the above-mentioned lifting rod in its raised position is rotatably installed in the box body, and
A contact portion is provided which contacts the magnet during the opening operation of the back cover and rotates it to release the elevating lever to which the magnet is attracted, and a contact portion between the front end of the lever and the lower back surface of the front cover is provided. By providing mutually removable hooks in between, the front cover can be automatically locked regardless of the location of the stored object, and the locked state can be changed by opening the back cover to take out the stored object. This provides a locking device for a box lid that can be unlocked.

る。The embodiment will be explained below with reference to the drawings. B is a cubic box body, 1 is a front cover, 2 is a back cover, and 3 is a fulcrum 4 on the bottom side of the box body B, which is horizontally mounted in the front and back direction of the box. The lower end of lever 5 is hinged to the rear end 3' of lever 3, and the middle part is attached to the box body B.
A contact 6 is supported on the inner surface of the lever 3, and when the back cover 2 is opened, its upper end is pushed down by the upper edge 2' of the opening cover 2 to push down the rear end 3' of the lever 3. The lower end is hinged at ``, and the middle part is supported on the inner surface of the box body B, 6' is the suction part at the upper end of the elevator rod 6, and 7 is the elevator rod 6.
Above, a magnet 9 hinged to the inner surface of the main body B via a fulcrum 8 is provided on the upper back surface of the front cover 1,
A contact portion 10 that contacts the magnet 7 and rotates it during the opening operation of the lever 3 is a hook 10a formed downward at the front end 3'' of the lever 3, and a hook 10a formed downward at the front end 3'' of the lever 3, and an upwardly directed hook 10a projected from the lower back surface 1' of the front cover 1. This is a hook part consisting of a hook 10b that can be engaged and detached from each other.
なお図中１１は、表蓋１が開放されたときに当接部９の
当接によって回転する磁石７と吸着してその回転位置に
固定するとともに、該磁石７を介して上記表蓋１の開放
位置を仮止めするような箱本体Ｂの内側面に設けた掛止
片Ｂａは箱の入口、Ｂｂは箱の出口で゛ある。In the figure, reference numeral 11 indicates that when the top cover 1 is opened, the magnet 7 rotates due to the contact of the abutting portion 9, and is attracted to the magnet 7 and fixed in its rotational position. A locking piece Ba provided on the inner surface of the box body B for temporarily fixing the open position is the entrance of the box, and Bb is an exit of the box.
つぎに上記の構成よりなるこの実施例の施錠および開錠
動作を、箱本体Ｂの使用とともに説明する。Next, the locking and unlocking operations of this embodiment constructed as described above will be explained together with the use of the box body B.
第１図の状態、すなわち、レバーＢの後端３′が下がっ
ているときは、同レバー３の前端３″が、昇降杆６とと
もに上昇しており、昇降杆６が磁石７に吸着されている
ので、同レバー前端３″の鉤１０ ａは開放されていて
、表蓋１は開放可能である。In the state shown in FIG. 1, that is, when the rear end 3' of the lever B is down, the front end 3'' of the lever 3 is rising together with the lifting rod 6, and the lifting rod 6 is attracted to the magnet 7. Therefore, the hook 10a on the front end 3'' of the lever is open, and the front cover 1 can be opened.
つぎに表蓋１を開いて収容物を入れようとすると、表蓋
１の開放によって当接部９がその前端によって磁石７を
強制的に回転せしめ、昇降杆６の吸着を開放するととも
に、掛止片１１に磁石７が吸着して、第２図に示すよう
に表蓋１をその開放位置に掛止する。Next, when the front cover 1 is opened to put in the stored items, the front end of the contact part 9 forcibly rotates the magnet 7 by opening the front cover 1, releasing the attraction of the lifting rod 6, and The magnet 7 is attracted to the stopper piece 11, and the top cover 1 is held in its open position as shown in FIG.
−前吸着を解かれた昇降杆６はその自重により、レバー
３の前端３″とともに下降して鉤１０ ａを施錠可能の
下降位置に位置させる。- The lifting rod 6, which has been released from the front suction, moves down together with the front end 3'' of the lever 3 due to its own weight, and positions the hook 10a in the lowered position where it can be locked.
ついで収容物を本体Ｂ内に入れ表蓋１を閉じると、共に
回転する当接部９の摺擦により磁石７が復位すると同時
に、その閉鎖時に開蓋１の下部裏面１′の鉤１０ ｂが
レバー前端３″の鉤１０ ａを若干押し上げたのち互い
に嵌合して鉤部１０が第３図に示すように表蓋１を施錠
状態に保つ。Next, when the stored items are put into the main body B and the front cover 1 is closed, the magnet 7 is returned to its position due to the friction of the abutment part 9 that rotates together with the magnet 7, and at the same time, the hook 10b on the lower back surface 1' of the open cover 1 is After the hooks 10a of the front end 3'' of the lever are pushed up a little, they fit together and the hooks 10 keep the front cover 1 in a locked state as shown in FIG.
上記箱内の収容物を取り出すために、裏蓋２を開くと、
その開放動作により接触子５がレバー３の後端３′とと
もに押し下げられ、逆にレバー前端３″とともに昇降杆
６が上昇して再び磁石７に吸着され、鉤部１０による表
蓋１の施錠を開放し、裏蓋２を閉じることによって、第
１図の状態に戻る。When you open the back cover 2 to take out the contents inside the box,
As a result of the opening operation, the contact 5 is pushed down together with the rear end 3' of the lever 3, and conversely, the lifting rod 6 rises together with the front end 3'' of the lever and is again attracted to the magnet 7, which locks the top cover 1 with the hook 10. By opening the case and closing the back cover 2, the state shown in FIG. 1 is returned.
前記の構成よりなり、上記のようにして使用される本考
案は、箱内に納める収容物の置き場所と無関係に、表蓋
