In addition, the front-rear direction X, the up-down direction Y, and the transverse direction Z of the locking device 10 respectively correspond to the front-rear direction, the up-down direction, and the transverse direction of the storage box 1.

本発明に係る収容ボックス１は、戸建て住宅の宅配ボックスやマンション等の集合ポスト等として好適に使用される。収容ボックス１の大きさ及び形状は、大小様々な荷物を収容できる限りにおいて図示した態様に限定されるものではない。また、施錠装置１０についても、後記の本願発明の効果を奏する限りにおいて、図示例のように断面矩形状ではなく、その外形が円形、楕円形、扁平形等の各種公知の形状であってもよい。施錠装置１０の操作者は、住人のほかに、住人が不在時に収容ボックス１に荷物を入れる郵便・宅配業者等を含む。 The storage box 1 according to the present invention is suitably used as a delivery box for a detached house, a collective post for an apartment, or the like. The size and shape of the storage box 1 are not limited to those shown in the drawings as long as large and small loads can be stored. In addition, as long as the locking device 10 achieves the effects of the present invention described later, the outer shape of the locking device 10 is not a rectangular shape as in the illustrated example, and the outer shape thereof may be various known shapes such as a circle, an ellipse, and a flat shape. Good. The operator of the locking device 10 includes, in addition to the resident, a postal / courier service provider who puts luggage in the storage box 1 when the resident is absent.

装置本体１１は、前面壁部２１、上壁部２２、下壁部２３及び第１及び第２側壁部２４，２５から外形が画成されたボックス形状を有する。前面壁部２１は、上下壁部２２，２３からさら上下方向Ｙの外側へ延出し、かつ、第１及び第２側壁部２４，２５からさらに横断方向Ｚの外側に延出する外周フランジ部２１ａを有する。装置本体１１は、収容ボックス１の筐体２の扉枠に位置する凹状のラッチ受け部２ａに進入・退出可能なラッチ１５と、ラッチ１５を装置本体１１の第１側壁部２４から進退出可能に操作するための操作レバー１６と、操作レバー１６と横断方向Ｚにおいて並ぶ指当て部１７とをさらに有する。操作レバー１６と指当て部１７とは、装置本体１１の前面壁部２１から前方へ突出している。 The apparatus main body 11 has a box shape whose outer shape is defined by a front wall portion 21, an upper wall portion 22, a lower wall portion 23, and first and second side wall portions 24 and 25. The front wall portion 21 extends from the upper and lower wall portions 22 and 23 to the outside in the vertical direction Y and extends from the first and second side wall portions 24 and 25 to the outer side in the transverse direction Z. Have The apparatus main body 11 can move into and out of a concave latch receiving portion 2a located on the door frame of the housing 2 of the housing box 1 and the latch 15 can advance and retreat from the first side wall portion 24 of the apparatus main body 11. And a finger rest 17 arranged in the transverse direction Z with the operation lever 16. The operation lever 16 and the finger pad 17 protrude forward from the front wall 21 of the apparatus body 11.

施錠装置１０のラッチ１５は、横断方向Ｚへスライド移動可能な操作レバー１６と連動しており、施錠状態において、操作レバー１６の移動は錠本体３０によって規制されている。したがって、扉３の施錠状態（規制ロック部材６０によるスライド部材５０の移動が規制された状態）においては、キー３３を所持していない第三者が操作レバー１６をスライド操作しようとしても操作レバー１６を移動させることはできない。キー３３を所持した操作者（主として住人）が、鍵孔３０ａにキー３３を挿入して回転操作することによって、操作レバー１６の移動規制が解除（解錠）される。解錠後、操作者が操作レバー１６を横断方向Ｚの内方へ向かう方向Ｐ１へ、すなわち、指当て部１７へ接近する方向へスライドさせることによって、ラッチ１５がラッチ受け部２ａから退出して扉を開放することができる。 The latch 15 of the locking device 10 is interlocked with the operation lever 16 that is slidable in the transverse direction Z. In the locked state, the movement of the operation lever 16 is regulated by the lock body 30. Therefore, in the locked state of the door 3 (the state in which the movement of the slide member 50 by the restriction lock member 60 is restricted), even if a third party who does not have the key 33 tries to slide the operation lever 16, the operation lever 16 Cannot be moved. When an operator (mainly a resident) having the key 33 inserts the key 33 into the keyhole 30a and performs a rotation operation, the movement restriction of the operation lever 16 is released (unlocked). After unlocking, the operator slides the operating lever 16 in the inward direction P1 in the transverse direction Z, that is, in the direction approaching the finger rest 17, so that the latch 15 is retracted from the latch receiving portion 2a. The door can be opened.

図２及び図４を参照すると、施錠装置１０は、錠本体３０以外の構成部品がプラスチック製であって、上下壁部２２，２３には複数の弾性係合爪１８，１９を有する。施錠装置１０を扉３に取り付ける際には、蓋体１２から後方へ延出する後方突起４９をスライド操作して、ばね付勢に抗してラッチ１５を装置本体１１の内部に移動させた状態で施錠装置１０を配置凹部５の取付孔の開口縁部に前面壁部２１の外周フランジ部２１ａを前側から押し当てるように嵌挿させる。それによって、弾性係合爪１８，１９が弾性変形するとともにその弾性反撥力によって取付孔から後方へ突出する矩形状の取付枠５ａに係止され、施錠装置１０が扉３に安定的に取り付けられる。このように、施錠装置１０を扉３の取付枠５ａに前面側からワンタッチで取り付けることができるので、ドライバー等の固定具を使用する場合に比べて、取付操作が簡易である。 Referring to FIGS. 2 and 4, in the locking device 10, components other than the lock body 30 are made of plastic, and the upper and lower wall portions 22 and 23 have a plurality of elastic engagement claws 18 and 19.

図２、図８（ａ），（ｂ）を参照すると、住人の不在時に荷物を収容ボックス１に収容する宅配業者等の配達人が、荷物を収容して施錠装置１０を施錠するときには、まず、収容ボックス１に荷物を収容した後に、規制ロック部材６０が係合手段８９によって蓋体１２の内面に掛止された状態にあるので、扉２の背面側に手を伸ばして規制レバー６８を把持したまま引き下げて規制ロック部材６０を下方へ移動させる。それによって、底壁部６１から下方へ延びる閂部６７がスライド部材５０の突子受孔５５に挿入され、スライド部材５０の移動が規制される。かかる状態においては、錠本体３０の係止板３７の係止端３７ａが規制ロック部材６０の被係止部分６９に当接される。 Referring to FIGS. 2, 8 (a) and 8 (b), when a delivery person such as a courier who accommodates luggage in the accommodation box 1 in the absence of a resident, accommodates the luggage and locks the locking device 10. After the baggage is stored in the storage box 1, the restriction lock member 60 is in a state of being hooked on the inner surface of the lid body 12 by the engaging means 89. Pulling down while holding, the restriction lock member 60 is moved downward. Accordingly, the flange portion 67 extending downward from the bottom wall portion 61 is inserted into the protrusion receiving hole 55 of the slide member 50, and the movement of the slide member 50 is restricted. In this state, the locking end 37 a of the locking plate 37 of the lock body 30 is brought into contact with the locked portion 69 of the restriction lock member 60.

次に、扉２を閉扉操作することによって、凸曲状の先端部を有するラッチ１５が、扉枠の突出部２ｂに摺接される。それによって、コイルばね８６が圧縮されて、ラッチ１５は僅かに横断方向Ｚの内側へ後退しながら前方へ移動し、ラッチ受け部２ａに進入して施錠される。施錠状態において、キー３３を所持していない第三者が、操作レバー１６を摘持してスライド操作しようとしても規制ロック部材６０によって施錠されているので、操作レバー１６が移動することはない。また、窓孔２７には、施錠を知らせる第１表示部８０ａが露出されているので、操作者等は、施錠装置１０が施錠状態であることを確認することができる。 Next, by closing the door 2, the latch 15 having a convex curved tip is brought into sliding contact with the protrusion 2 b of the door frame. Accordingly, the coil spring 86 is compressed, and the latch 15 moves forward while slightly retracting inward in the transverse direction Z, enters the latch receiving portion 2a, and is locked. In the locked state, even if a third party who does not have the key 33 tries to perform the sliding operation by holding the operating lever 16, the operating lever 16 is not moved because it is locked by the restriction lock member 60. Moreover, since the 1st display part 80a which notifies locking is exposed in the window hole 27, the operator etc. can confirm that the locking device 10 is a locked state.

図９（ａ），（ｂ）を参照すると、帰宅した住人が収容ボックス１を開扉するときには、前面壁部２１に位置する鍵孔３０ａにキー３３を挿入して係止板３７が上方Ｒ１へ旋回するように回転操作し、規制ロック部材６０を上方へ移動させることによって閂部６７が突子受孔５５から退出し、規制ロック（施錠）が解除される。規制ロック部材６０は引き上げられた状態で蓋体１２に係合手段８９を介して掛止されるので、住人は、キー３３から手を離した状態で操作レバー１６を指当て部１７に接近するようにスライド操作することによって、ラッチ１５をラッチ受け部２ａから退出させて扉３を開放することができる。住人が荷物を取り出した後、規制ロック部材６０が上方に掛止された状態のまま扉を閉めることによって、配達人が施錠する前の状態に戻る。 Referring to FIGS. 9A and 9B, when the resident returning home opens the storage box 1, the key 33 is inserted into the key hole 30a located in the front wall portion 21, and the locking plate 37 is moved upward R1. Rotation is performed so as to turn to the right, and the restriction lock member 60 is moved upward, whereby the flange portion 67 is retracted from the protrusion receiving hole 55 and the restriction lock (locking) is released. Since the regulation lock member 60 is hooked to the lid 12 via the engaging means 89 in the pulled up state, the resident approaches the operation lever 16 to the finger rest 17 while releasing the hand from the key 33. By performing the sliding operation in this manner, the latch 15 can be retracted from the latch receiving portion 2a and the door 3 can be opened. After the resident takes out the package, the door is closed with the regulation lock member 60 hooked upward, so that the state before the delivery person locks is restored.

本実施形態に係る施錠装置１０においては、電気錠等のように電源を必要としないので、戸建住宅の門扉や玄関口の近傍に後付けで設置することができる。また、電気部品を必要とせず、かつ、ケース２０に収容される部材が主としてラッチ部材４０、スライド部材５０、規制ロック部材６０から構成されていることから従来の収容ボックス用の施錠装置に比べて簡易な構成を有し、低コストで製造することができる。さらに、従来の電気錠等のように配達人がメモ用紙等によって暗証番号を残す必要がなく、住人がメモ用紙に従って暗証番号を入力する等の手間が不要であって、すばやく解錠することができる。なお、図示していないが、収容ボックス１の筐体２内に、配達人が住人の不在時に荷物を配達したことの証明を得るために配達伝票に押印する手段として、住人の印鑑を配置する配置台を設置してもよい。 In the locking device 10 according to the present embodiment, a power source is not required unlike an electric lock or the like, so that it can be installed in the vicinity of a gate or a doorway of a detached house. In addition, since no member is required and the member accommodated in the case 20 is mainly composed of the latch member 40, the slide member 50, and the regulating lock member 60, it is compared with a conventional locking device for a storage box. It has a simple configuration and can be manufactured at low cost. Further, it is not necessary for the delivery person to leave the personal identification number with a memo paper or the like unlike a conventional electric lock, etc., and it is unnecessary for the resident to enter the personal identification number according to the memo paper, and the unlocking can be performed quickly. Although not shown, a resident seal is arranged in the housing 2 of the storage box 1 as means for stamping a delivery slip in order to obtain proof that the delivery person has delivered the package when the resident is absent. A placement table may be installed.

加えて、ラッチ１５とスライド移動可能な操作レバー１６とが別体の部材から形成されておらず、一体の部材から形成されていることによって、スライド操作によって確実にラッチ１５をラッチ受け部２ａから退出させることができる。さらに、操作レバー１６と横断方向Ｚにおいて並ぶように前面壁部２１から突出した指当て部１７が位置することによって、例えば、人差し指で指当て部１７を抑えながらそれに接近するように親指で操作レバー１６をスライド移動させればよいので、片手でスムーズに操作を行うことができる。操作レバー１６は、その一部をレバー挿通孔２８の開口縁部をガイドとしてそれに摺接しながら移動してもよい。 In addition, the latch 15 and the slidable operation lever 16 are not formed as separate members, but are formed as an integral member, so that the latch 15 can be reliably removed from the latch receiving portion 2a by a sliding operation. Can be withdrawn. Further, by positioning the finger rest 17 protruding from the front wall portion 21 so as to be aligned with the operation lever 16 in the transverse direction Z, for example, the operation lever is operated with the thumb so as to approach the finger rest 17 while holding the finger rest 17 with the index finger. Since 16 may be slid, the operation can be performed smoothly with one hand. The operation lever 16 may move while a part of the operation lever 16 is in sliding contact with the opening edge of the lever insertion hole 28 as a guide.

再び、図７（ａ），（ｂ）を参照すると、ラッチ部材４０の当接面４１ａ，４１ｂに当接されるスライド部材５０のガイド壁部５２ａ，５２ｂの幅寸法（上下方向Ｙの寸法）は、当接面４１ａ，４１ｂの幅寸法（上下方向Ｙの寸法）に比べて小さい。すなわち、ガイド壁部５２ａ，５２ｂは幅狭のリブ状であって面状に当接面４１ａ，４１ｂに当接されるものではないから、摺接するときに摩擦抵抗が小さくなって、比較的に小さな力でスライド操作を行うことができる。また、スライド部材５０のガイド壁部５２ａが摺接されるケース２０の分離壁部８４ａ，８４ｂの下面の前方側には、横断方向Ｚへ間隔を空けて位置する複数の突起８８が設けられていることによって、スライド部材５０が分離壁部８４ａ，８４ｂと摺接するときに摩擦抵抗が低減される。 Referring to FIGS. 7A and 7B again, the width dimension (dimension in the vertical direction Y) of the guide wall portions 52a and 52b of the slide member 50 abutted against the abutment surfaces 41a and 41b of the latch member 40. Is smaller than the width dimension (dimension in the vertical direction Y) of the contact surfaces 41a and 41b. That is, since the guide wall portions 52a and 52b are narrow ribs and are not brought into contact with the contact surfaces 41a and 41b in a planar shape, the frictional resistance is reduced when they are slidably contacted. Slide operation can be performed with a small force. In addition, a plurality of protrusions 88 that are spaced apart in the transverse direction Z are provided on the front side of the lower surfaces of the separation wall portions 84a and 84b of the case 20 with which the guide wall portion 52a of the slide member 50 is slidably contacted. Thus, the frictional resistance is reduced when the slide member 50 is in sliding contact with the separation wall portions 84a and 84b.

図３を参照すると、装置本体１１の前面壁部２１には、緊急的に施錠を解除するための破壊ポイント９０が位置する。破壊ポイント９０は、前面壁部２１のレバー挿通孔２８の第１側壁部２４側の上方に位置しており、ケース２０内部においてスライド部材５０の突子受孔５５に挿入された閂部６７の基端部近傍を含む領域である。例えば、住人がキー３３を喪失した場合において、非常の施錠装置１０の開錠手段として、前面壁部２１の破壊ポイント９０をドリル等の工具を使用して穴を開けて破壊する。破壊ポイント９０を破壊することによって、ケース２０内の規制ロック部材６０の閂部６７が破壊されてスライド部材５０の移動規制が解除され、扉を開放することができる。第三者に破壊ポイント９０の位置を把握されないようにするために、前面壁部２１には、しるし等を付さないことが好ましいが、一見してそれが破壊ポイント９０であると認識されない限りにおいて、円形の溝を施したり、シールを貼付したりする等の住人のみが認識しうる方法でしるしを付すことによって、破壊操作を容易に行うことができる。 Referring to FIG. 3, a destruction point 90 for urgently releasing the lock is located on the front wall portion 21 of the apparatus main body 11. The breaking point 90 is positioned above the first side wall portion 24 side of the lever insertion hole 28 of the front wall portion 21, and the flange portion 67 inserted into the protrusion receiving hole 55 of the slide member 50 inside the case 20. This is a region including the vicinity of the base end. For example, when the resident loses the key 33, the breaking point 90 of the front wall portion 21 is broken by using a tool such as a drill as an unlocking means of the emergency locking device 10. By destroying the destruction point 90, the flange portion 67 of the restriction lock member 60 in the case 20 is destroyed, the movement restriction of the slide member 50 is released, and the door can be opened. In order to prevent a third party from grasping the position of the destruction point 90, it is preferable that the front wall portion 21 is not provided with a sign or the like, but unless it is recognized as the destruction point 90 at first glance. In this case, the destructive operation can be easily performed by giving a mark by a method that only a resident can recognize, such as applying a circular groove or attaching a seal.

また、スライド部材５０の操作レバー１６の第１側壁部２４側の側面１６ａと前面壁部２１の指当て部１７の第２側壁部２５側の側面１７ａとが凹面状を有している。操作レバー１６の側面１６ａと指当て部１７の側面１７ａとがかかる形状を有することによって、操作者は親指と人差指とを安定的に押し当てることができるので、スムーズに操作レバー１６のスライド操作を行うことができる。 Further, the side surface 16 a on the first side wall portion 24 side of the operation lever 16 of the slide member 50 and the side surface 17 a on the second side wall portion 25 side of the finger pad portion 17 of the front wall portion 21 have a concave shape. Since the side surface 16a of the operation lever 16 and the side surface 17a of the finger pad 17 have such a shape, the operator can stably press the thumb and the index finger, so that the slide operation of the operation lever 16 can be performed smoothly. It can be carried out.
