特許文献1に開示されている鍵等の収納装置では、逆U字状のシャックルをドアノブの軸に係着可能な着脱可能に取り付けるようにしていることから、ドアノブの形態よっては収納ボックスをドアの部に取り付けられず、使用環境が限定されるという不都合を有しているうえ、収納空間の開口部を覆っている扉体の開閉操作時に施錠―解錠するための電動式作動機器が収納されていることから、該作動機器を駆動するために制御機器や駆動機器を配置しなければならず、コストアップとなるだけでなく、収納空間を大きく取れないという不都合があった。   In the storage device for a key or the like disclosed in Patent Document 1, an inverted U-shaped shackle is detachably attached to the shaft of the doorknob so that the storage box is attached to the door depending on the form of the doorknob. In addition to the inconvenience that the usage environment is limited, the motor-operated device for locking and unlocking is stored when opening and closing the door that covers the opening of the storage space. Therefore, in order to drive the operating device, it is necessary to dispose a control device and a driving device, which not only increases costs but also has a disadvantage that a large storage space cannot be obtained.

また、特許文献2、3、4に開示されている錠装置では、開閉扉に相対移動可能な状態で組み付けた軸の先端部に支持体を介してラッチ機構を配置し、ラッチ機構のラッチ版を軸の軸心に沿う方向で揺動可能に構成するとともにこのラッチ板を施錠側に弾性付勢し、扉の開き作動に基づき、閉じ側に付勢している弾性力に抗してラッチ板を揺動させることでラッチ板とストッパー片との係合を解除し、軸の回転に伴いラッチ板の回転を規制するようにしてあることから、軸芯に沿って揺動するラッチ板の揺動スペースを確保しておかなければならず、ラッチ機構の奥行寸法・高さ寸法が大型化してしまううえ、ラッチ機構が複雑化して、安定した作動を確保できる耐久性に不安があった。   Further, in the lock devices disclosed in Patent Documents 2, 3, and 4, a latch mechanism is disposed via a support at the tip of a shaft assembled in a state of being relatively movable with respect to the open / close door, and the latch plate of the latch mechanism The latch plate is configured to be swingable in a direction along the axis of the shaft, and the latch plate is elastically biased toward the locking side, and latches against the elastic force biased toward the closing side based on the opening operation of the door. Since the latch plate and the stopper piece are disengaged by swinging the plate, and the rotation of the latch plate is regulated as the shaft rotates, the latch plate swinging along the shaft core The swinging space must be secured, the depth and height dimensions of the latch mechanism are increased, and the latch mechanism is complicated, and there is concern about durability that can ensure stable operation.

本発明は、このような点に鑑み提案されたものであり、収納ボックスの収納空間内で占有されてしまう錠装置の設置スペースを小さくすることができるとともに、長期にわたって安定した作動を行える収納ボックスの錠装置を提供することを目的とする。   The present invention has been proposed in view of the above points, and can reduce the installation space of the lock device that is occupied in the storage space of the storage box, and can be stably operated over a long period of time. An object of the present invention is to provide a locking device.

図1は、本発明の一実施形態を示す鍵収納ボックスの分解斜視図であり、この収納ボックスは、前面に開口部を有する金属製ボックスのケース本体(1)と、ケース本体(1)の開口部(2)を閉塞する扉体(3)とを備えており、この扉体(3)は、ケース本体(1)の開口下端部に俯仰揺動可能に組み付けてある。   FIG. 1 is an exploded perspective view of a key storage box showing an embodiment of the present invention. The storage box includes a case main body (1) of a metal box having an opening on the front surface, and a case main body (1). And a door body (3) that closes the opening (2). The door body (3) is assembled to the lower end of the opening of the case main body (1) so as to be swingable.

ケース本体(1)は鉄又は鋼で形成し、ABS樹脂でコーティングした前面開放状のボックスであり、その内部に位置する空間部分(4)の上部に後述するロック板受止部(5)が固定されるとともに、下部に扉体(3)を揺動支持する保持枠(6)が組み付けてある。これらロック板受止部(5)及び保持枠(6)は、図3及び図4に示すようにケース本体(1)の背面壁(7)にボックス内部から止めつけてある。ここでケース本体(1)を金属ブロックから削出し加工で形成した場合には、対象物が鍵収納ボックスであることから、外部からの破壊を可及的に抑制することが出来る。   The case body (1) is an open front box formed of iron or steel and coated with ABS resin, and a lock plate receiving portion (5) to be described later is provided above the space portion (4) located inside the case body. A holding frame (6) that is fixed and swings and supports the door body (3) is assembled to the lower part. The lock plate receiving portion (5) and the holding frame (6) are fixed to the back wall (7) of the case body (1) from the inside of the box as shown in FIGS. Here, when the case main body (1) is formed by machining from a metal block, since the object is a key storage box, destruction from the outside can be suppressed as much as possible.

前述のロック板受止部(5)は、ケース本体(1)の背面壁(7)に止めつけ固定する固定部(5a)と、その固定部(5a)の上部から前方に連出した庇部(5b)とからなり、庇部(5b)の前端縁に沿ってロック板受止溝(5c)が刻設してある。   The lock plate receiving portion (5) is fixed to the rear wall (7) of the case main body (1) and fixed to the rear wall (7), and the hook protruding from the upper portion of the fixed portion (5a) to the front. The lock plate receiving groove (5c) is formed along the front edge of the flange portion (5b).

扉体(3)のボックス内側での上部には、錠装置(8)が組み付けてある。この錠装置(8)は、図3及び図4に示すように、扉体(3)の上部に形成した貫通孔(9)に進退可能に組み込まれた操作軸(10)と、該操作軸(10)に相対回動不能に装着されかつ操作軸(10)の進退移動は許容するロック板(11)と、操作軸(10)を押し込み進入させない時には操作軸(10)を進退可能にかつ回動不能に支持させ、操作軸(10)を押し込み進入させた時には操作軸(10)を回動可能に支持させる支持ブロック(12)と、支持ブロック(12)の内側端面に組み付けた支持板(13)と、操作軸(10)の内端側に形成した凹嵌部に組込まれて操作軸(10)を進出側に弾性付勢する圧縮バネ(14)とで構成してある。   A lock device (8) is assembled to the upper part of the door body (3) inside the box. As shown in FIGS. 3 and 4, the locking device (8) includes an operation shaft (10) incorporated in a through hole (9) formed in the upper portion of the door body (3) so as to be able to advance and retreat, and the operation shaft. A lock plate (11) that is mounted on (10) so as not to be relatively rotatable and allows the operation shaft (10) to move forward and backward, and when the operation shaft (10) is not pushed in, the operation shaft (10) can be moved forward and backward. A support block (12) for supporting the operation shaft (10) so as to be rotatable when the operation shaft (10) is pushed in and supported, and a support plate assembled to the inner end face of the support block (12). (13) and a compression spring (14) which is incorporated in a recessed fitting portion formed on the inner end side of the operation shaft (10) and elastically biases the operation shaft (10) toward the advance side.

操作軸(10)には、扉体(3)側の端部に操作用摘み(15)が形成されるとともに、この摘み(15)に繋がる部分に南京錠(16)のツル(16a)を挿通させる挿通孔(17)が透設してある。
このツル(16a)を挿通させるツル挿通孔(17)は、前記操作軸(10)が圧縮バネ(14)で付勢されている状態では、扉体(3)の表面から突出しており、操作軸(10)を圧縮バネ(14)の弾発力に抗してケース本体(1)内に退入させた状態では、扉体(3)に形成されている貫通孔(9)内に入り込む状態に形成してある。
The operation shaft (10) has an operation knob (15) formed at the end on the door body (3) side, and a padlock (16) crane (16a) is inserted into a portion connected to the knob (15). The insertion hole (17) to be made transparent is provided.
The temple insertion hole (17) through which the temple (16a) is inserted protrudes from the surface of the door body (3) when the operation shaft (10) is biased by the compression spring (14). In a state where the shaft (10) is retracted into the case body (1) against the elastic force of the compression spring (14), the shaft (10) enters the through hole (9) formed in the door body (3). It is formed in a state.

前記操作軸(10)の内端部には鍔部(18)が形成してあり、この鍔部(18)は円周面の一部を前記ツル挿通孔(17)の貫通方向と平行に切除して略小判型に形成してある。さらに、操作軸(10)の前記挿通孔(17)と鍔部(18)との間に位置する軸部分の円周面を前記鍔部(18)の平行面と約90度位相が異なる平面部を有する略小判型に形成してロック板挿嵌部(19)としてある。   A flange portion (18) is formed at the inner end of the operation shaft (10), and this flange portion (18) has a part of the circumferential surface parallel to the penetrating direction of the temple insertion hole (17). It is cut out to form a roughly oval shape. Further, the circumferential surface of the shaft portion located between the insertion hole (17) and the flange portion (18) of the operating shaft (10) is a plane that is approximately 90 degrees out of phase with the parallel surface of the flange portion (18). A lock plate insertion portion (19) is formed in a substantially oval shape having a portion.

ロック板(11)は、円板部(20)での円周面の一部を半径方向に延出させて係合突片(21)に形成するとともに、円板部(20)に前記操作軸(10)の軸部分に形成したロック板挿嵌部(19)に外嵌する小判型の装着孔(22)が形成してある。
この小判型の装着孔(22)に、操作軸(10)のロック板挿嵌部(19)が貫装されることで、ロック板(11)は、操作軸(10)に相対回動不能に装着されかつ操作軸(10)の進退移動は許容するように構成される。
The lock plate (11) is formed on the engagement protrusion (21) by extending a part of the circumferential surface of the disc portion (20) in the radial direction, and the operation is performed on the disc portion (20). An oval mounting hole (22) is formed which is fitted around a lock plate insertion portion (19) formed in the shaft portion of the shaft (10).
When the lock plate insertion portion (19) of the operation shaft (10) is inserted into the oval mounting hole (22), the lock plate (11) cannot rotate relative to the operation shaft (10). And is configured to allow forward and backward movement of the operating shaft (10).

支持ブロック(12)は、操作軸(10)に形成されている前記ツル挿通孔(17)が水平に位置する姿勢で、操作軸(10)の内端に形成されている鍔部(18)が挿通可能な操作軸挿通孔(23)と、操作軸(10)に挿嵌保持したロック板(11)が操作軸(10)の軸心周りに回動した際に円板部(20)及び係合突片(21)の回動を許容する凹嵌部(24)とを有している。   The support block (12) has a collar portion (18) formed at the inner end of the operation shaft (10) in a posture in which the temple insertion hole (17) formed in the operation shaft (10) is positioned horizontally. When the operation shaft insertion hole (23) through which the shaft can be inserted and the lock plate (11) inserted and held in the operation shaft (10) are rotated around the axis of the operation shaft (10), the disk portion (20) And a concave fitting portion (24) that allows the engagement protrusion (21) to rotate.

操作軸挿通孔(23)は、操作軸(10)の鍔部(13)と同形の小判型で、この操作軸挿通孔(23)の内周面は鍔部の外周面との間にわずかな隙間を持って形成してある。そして、操作軸(10)は前述のように、圧縮バネ(14)で扉体(3)から外部に突出するように弾性付勢されていることから、鍔部(18)の形状と操作軸挿通孔(22)の形状とが一致している際には、操作軸(10)の鍔部(18)は操作軸挿通孔(23)の内部に嵌り込んで、操作軸(10)の回動は不能に抑制されることになり、操作軸(10)に嵌着されているロック板(11)は、回動することが出来ず、ケース本体(1)に形成されているロック板受止部(5)との係合状態にあるので、扉体(3)は開扉不能となる。   The operation shaft insertion hole (23) is an oval shape having the same shape as the flange (13) of the operation shaft (10), and the inner peripheral surface of the operation shaft insertion hole (23) is slightly between the outer peripheral surface of the flange. It is formed with a large gap. Since the operating shaft (10) is elastically biased so as to protrude from the door body (3) by the compression spring (14) as described above, the shape of the flange (18) and the operating shaft are When the shape of the insertion hole (22) matches, the flange (18) of the operation shaft (10) is fitted into the operation shaft insertion hole (23), and the rotation of the operation shaft (10) is performed. The movement of the lock plate (11) fitted to the operating shaft (10) cannot be rotated, and the lock plate holder formed on the case body (1) cannot be rotated. Since it is in an engagement state with a stop part (5), a door body (3) cannot be opened.

一方、鍔部(18)の形状と操作軸挿通孔(23)の形状とが一致している状態で操作軸(10)を圧縮バネ(14)の弾性付勢力に抗して軸芯に沿って押し込むと、鍔部(18)が操作軸挿通孔(23)の領域を通過して支持ブロック(12)の内側に形成した圧縮バネ(12)の収容空間部分に進出すること操作軸挿通孔(23)での規制が解除されることから、鍔部(18)回動可能となる。そして、操作軸(10)を押し込んだ状態で、操作軸(10)を回動させることで、操作軸(10)に嵌着されているロック板(11)は回動する。この状態で操作軸(10)を90度回動させると、ロック板(11)がケース本体(1)に形成されているロック板受止部(5)から外れて、開扉可能な状態となる。なお、この状態では鍔部(18)の形状と操作軸挿通孔(23)の形状とが一致していないので操作軸(10)に作用している押し込み力を取り除いても操作軸(10)に作用している圧縮バネ(14)の弾性力で鍔部(18)の端面部分が支持ブロック(12)の奥側端面に受け止められ、開扉可能な状態は維持されることになる。   On the other hand, the operating shaft (10) is moved along the shaft core against the elastic biasing force of the compression spring (14) in a state in which the shape of the flange portion (18) and the shape of the operating shaft insertion hole (23) coincide. When pushed in, the collar portion (18) passes through the region of the operation shaft insertion hole (23) and advances into the accommodating space portion of the compression spring (12) formed inside the support block (12). Since the restriction at (23) is released, the collar portion (18) can be rotated. Then, the lock plate (11) fitted to the operation shaft (10) is rotated by rotating the operation shaft (10) while the operation shaft (10) is pushed in. When the operating shaft (10) is rotated 90 degrees in this state, the lock plate (11) is disengaged from the lock plate receiving portion (5) formed in the case body (1), and the door can be opened. Become. In this state, since the shape of the flange (18) and the shape of the operation shaft insertion hole (23) do not match, the operation shaft (10) can be removed even if the pushing force acting on the operation shaft (10) is removed. The end surface portion of the flange portion (18) is received by the back end surface of the support block (12) by the elastic force of the compression spring (14) acting on the door, and the openable state is maintained.
