（第１実施形態）
＜１．補助錠装置の概要＞
本実施形態は、図１に示されるように、室内側に揺動して開く扉１を有する扉装置に本開示に係る補助錠装置１０の一例が適用されたものである。扉１の扉枠２には、当該扉１のラッチボルト３が嵌り込み可能な凹部４が設けられている。 (First Embodiment)
<1. Overview of auxiliary lock device>
In this embodiment, as shown in FIG. 1, an example of the auxiliary lock device 10 according to the present disclosure is applied to a door device having a door 1 that swings open toward the room. The door frame 2 of the door 1 is provided with a recess 4 into which the latch bolt 3 of the door 1 can be fitted.

ラッチボルト３は、扉１に対して出没可能な閂である。当該ラッチボルト３が凹部４に嵌り込んだ状態では、扉１が揺動することが規制される。なお、ラッチボルト３のうち揺動方向一方側（本実施形態では、室外側）には、傾斜面が設けられている。 The latch bolt 3 is a bar that can appear and disappear with respect to the door 1. When the latch bolt 3 is fitted in the recess 4, the door 1 is restricted from swinging. An inclined surface is provided on one side of the latch bolt 3 in the swing direction (in the present embodiment, the outdoor side).

補助錠装置１０は、図２に示されるように、係止プレート１１、ロック部材１２及び脱落規制部１３等を少なくとも備える。係止プレート１１は、ラッチボルト３が貫通可能な貫通穴１１Ａを有する帯板状の金属板である。 As shown in FIG. 2, the auxiliary lock device 10 includes at least a locking plate 11, a lock member 12, a dropout restricting portion 13, and the like. The locking plate 11 is a strip-shaped metal plate having a through hole 11A through which the latch bolt 3 can penetrate.

当該係止プレート１１には、図３に示されるように、少なくとも１つ（本実施形態では、２つの）の係止片１４が設けられている。２つの係止片１４は、係止プレート１１の板面から突出した突起部であって、凹部４に嵌り込み可能な突起部である（図１参照）。 As shown in FIG. 3, the locking plate 11 is provided with at least one (two in this embodiment) locking pieces 14. The two locking pieces 14 are protrusions protruding from the plate surface of the locking plate 11 and are protrusions that can be fitted into the recess 4 (see FIG. 1).

本実施形態に係る２つの係止片１４は、略矩形状に形成された貫通穴１１Ａの外縁から延出している。具体的には、２つの係止片１４は、貫通穴１１Ａの外縁を構成する４つの辺のうち上下方向と直交する２つの外縁辺に設けられている。 The two locking pieces 14 according to the present embodiment extend from the outer edge of the through hole 11A formed in a substantially rectangular shape. Specifically, the two locking pieces 14 are provided on two outer edge edges orthogonal to the vertical direction among the four sides constituting the outer edge of the through hole 11A.

上下方向とは、係止プレート１１の長手方向及び係止プレート１１の厚み方向と直交する方向いう。なお、本実施形態に係る上下方向は、係止プレート１１が扉枠２に装着された状態における鉛直方向と略平行な方向である。 The vertical direction means a direction orthogonal to the longitudinal direction of the locking plate 11 and the thickness direction of the locking plate 11. The vertical direction according to the present embodiment is a direction substantially parallel to the vertical direction when the locking plate 11 is mounted on the door frame 2.

ロック部材１２は、係止プレート１１に係止された状態（図１参照）で、当該係止プレート１１の長手方向に変位可能な状態と当該変位が不可な状態とを切替可能な部材である。そして、当該ロック部材１２には、扉１と接触可能な当て面１２Ａが設けられている（図１参照）。 The lock member 12 is a member capable of switching between a state in which the locking plate 11 is displaced in the longitudinal direction and a state in which the displacement is not possible in a state of being locked to the locking plate 11 (see FIG. 1). .. The lock member 12 is provided with a contact surface 12A that can come into contact with the door 1 (see FIG. 1).

すなわち、係止プレート１１には、図２に示されるように、ロック部材１２がスライド可能に嵌り込む長穴１１Ｂが設けられている。このため、ロック部材１２は、長穴１１Ｂの長径方向、つまり係止プレート１１の長手方向にスライド変位可能である。 That is, as shown in FIG. 2, the locking plate 11 is provided with an elongated hole 11B into which the lock member 12 is slidably fitted. Therefore, the lock member 12 can be slidably displaced in the major axis direction of the elongated hole 11B, that is, in the longitudinal direction of the locking plate 11.

そして、長穴１１Ｂの外縁には、ロック部材１２と係止可能な複数の凹部１１Ｃが設けられている。ロック部材１２には、それら凹部１１Ｃのいずれかに嵌り込み可能な係止突起部（図示せず。）が設けられている。 A plurality of recesses 11C that can be locked with the lock member 12 are provided on the outer edge of the elongated hole 11B. The lock member 12 is provided with a locking protrusion (not shown) that can be fitted into any of the recesses 11C.

当該係止突起部は、凹部１１Ｃに嵌り込んで係止プレート１１に係止される位置と当該位置から離脱した位置との間で弾性的に変位可能である。このため、ロック部材１２が係止プレート１１に対して変位可能となる状態と変位不可となる状態とが切り替え可能となる。 The locking protrusion is elastically displaceable between a position where it fits into the recess 11C and is locked to the locking plate 11 and a position where it is detached from the position. Therefore, it is possible to switch between a state in which the lock member 12 can be displaced with respect to the locking plate 11 and a state in which the lock member 12 cannot be displaced.

脱落規制部１３は、２つの係止片１４が凹部４に嵌り込んだときにおいて（図１参照）、当該係止片１４を着脱自在な状態で当該凹部４に固定するための部材である。 The dropout control unit 13 is a member for fixing the locking piece 14 to the recess 4 in a detachable state when the two locking pieces 14 are fitted into the recess 4 (see FIG. 1).

なお、「係止片１４が着脱自在に固定されている」とは、例えば、「補助錠装置１０の利用者が、ドライバ等の工具を用いることなく、容易に（ワンタッチで）係止プレート１１を扉枠２に対して着脱できる」という意味である。 In addition, "the locking piece 14 is detachably fixed" means, for example, "the user of the auxiliary locking device 10 can easily (one-touch) the locking plate 11 without using a tool such as a screwdriver. Can be attached to and detached from the door frame 2. "

＜２．脱落規制部の詳細＞
脱落規制部１３は、図４に示されるように、弾性変形可能なバネ部１５により構成されている。バネ部１５には、押圧部１５Ａが設けられている。そして、本実施に係るバネ部１５は、係止プレート１１に着脱可能に装着されている。 <2. Details of the dropout control department>
As shown in FIG. 4, the dropout restricting portion 13 is composed of an elastically deformable spring portion 15. The spring portion 15 is provided with a pressing portion 15A. The spring portion 15 according to the present implementation is detachably attached to the locking plate 11.

押圧部１５Ａは、図１に示されるように、２つの係止片１４が扉枠２の凹部４に嵌り込んだときに弾性変形して当該凹部４の内面に圧接する部位である。そして、当該押圧部１５Ａは、係止プレート１１の長手方向において、２つの係止片１４を挟んでロック部材１２と反対側に位置している。 As shown in FIG. 1, the pressing portion 15A is a portion that elastically deforms when the two locking pieces 14 are fitted into the recess 4 of the door frame 2 and presses against the inner surface of the recess 4. The pressing portion 15A is located on the opposite side of the locking member 12 with the two locking pieces 14 interposed therebetween in the longitudinal direction of the locking plate 11.

バネ部１５は、図２に示されるように、押圧部１５Ａに加えて、係止片１４と同数（本実施形態では、２つ）の接触片１５Ｂを有している。なお、押圧部１５Ａ及び２つの接触片１５Ｂは、バネ鋼鋼材等にて一体成形された一体品である。 As shown in FIG. 2, the spring portion 15 has the same number (two in this embodiment) of contact pieces 15B as the locking pieces 14 in addition to the pressing portion 15A. The pressing portion 15A and the two contact pieces 15B are integrally formed of a spring steel material or the like.

２つの接触片１５Ｂは、図４に示されるように、対応する係止片１４に接触する部位である。具体的には、２つの接触片１５Ｂは、２つの係止片１４を上下方向から挟み込むように各係止片１４に接触する。 The two contact pieces 15B are sites that come into contact with the corresponding locking piece 14, as shown in FIG. Specifically, the two contact pieces 15B come into contact with each of the locking pieces 14 so as to sandwich the two locking pieces 14 from above and below.

そして、接触片１５Ｂ及び係止片１４の一方（本実施形態では、係止片１４）には凹み部１４Ａが設けられ、他方（本実施形態では、接触片１５Ｂ）には当該凹み部１４Ａに嵌り込んだ突起状のボス部１５Ｃが設けられている。 One of the contact piece 15B and the locking piece 14 (the locking piece 14 in the present embodiment) is provided with the recessed portion 14A, and the other (the contact piece 15B in the present embodiment) is provided with the recessed portion 14A. A protruding boss portion 15C that is fitted is provided.

本実施形態に係る凹み部１４Ａは、係止片１４を厚み方向（本実施形態では、上下方向）に貫通する貫通穴にて構成されている。なお、バネ部１５には係止部１５Ｄ（図２参照）も設けられている。係止部１５Ｄは、係止プレート１１に係止される部位である。 The recessed portion 14A according to the present embodiment is configured by a through hole penetrating the locking piece 14 in the thickness direction (vertical direction in the present embodiment). The spring portion 15 is also provided with a locking portion 15D (see FIG. 2). The locking portion 15D is a portion to be locked to the locking plate 11.

このため、バネ部１５は、２つのボス部１５Ｃが対応する凹み部１４Ａに嵌り込み、かつ、係止部１５Ｄが係止プレート１１に係止された状態で、２つの接触片１５Ｂが２つの係止片１４を上下方向から挟み込むことにより係止プレート１１に固定される。 Therefore, in the spring portion 15, the two contact pieces 15B are two in a state where the two boss portions 15C are fitted into the corresponding recessed portions 14A and the locking portions 15D are locked to the locking plate 11. The locking piece 14 is fixed to the locking plate 11 by sandwiching it from above and below.

＜３．本実施形態に係る補助錠装置の使用方法及び特徴＞
利用者は、先ず、係止プレート１１の貫通穴１１Ａの位置がラッチボルト３の位置に合致するように、２つの係止片１４を扉枠２の凹部４に嵌め込む。これにより、押圧部１５Ａが弾性変形して当該押圧部１５Ａが凹部４の内面に圧接するため、係止プレート１１が扉枠２に固定された状態となる（図１参照）。 <3. Usage and features of the auxiliary lock device according to this embodiment>
First, the user fits the two locking pieces 14 into the recess 4 of the door frame 2 so that the position of the through hole 11A of the locking plate 11 matches the position of the latch bolt 3. As a result, the pressing portion 15A is elastically deformed and the pressing portion 15A is in pressure contact with the inner surface of the recess 4, so that the locking plate 11 is fixed to the door frame 2 (see FIG. 1).

次に、利用者は、当て面１２Ａが扉１に接触する位置、又は当て面１２Ａが扉１に十分に近接した位置までロック部材１２をスライド移動させた後、その位置にてロック部材１２の変位を規制する。 Next, the user slides the lock member 12 to a position where the contact surface 12A contacts the door 1 or a position where the contact surface 12A is sufficiently close to the door 1, and then the lock member 12 is moved at that position. Regulate displacement.

これにより、扉１を開く力が扉１に作用した場合であっても、当該扉１がロック部材１２及び係止プレート１１を介して扉枠２に係止された状態となるので、扉１が開くことが禁止される。 As a result, even when the force for opening the door 1 acts on the door 1, the door 1 is locked to the door frame 2 via the lock member 12 and the locking plate 11, so that the door 1 is in a state of being locked to the door frame 2. Is prohibited from opening.

押圧部１５Ａは、係止プレート１１の長手方向において、係止片１４を挟んでロック部材１２と反対側に位置している（図１参照）。これにより、扉１を開く力が扉１に作用した場合であっても、押圧部１５Ａを押し潰す力が当該押圧部１５Ａに作用しない。したがって、押圧部１５Ａが塑性変形してしまうことが防止される。 The pressing portion 15A is located on the side opposite to the locking member 12 with the locking piece 14 interposed therebetween in the longitudinal direction of the locking plate 11 (see FIG. 1). As a result, even when the force for opening the door 1 acts on the door 1, the force for crushing the pressing portion 15A does not act on the pressing portion 15A. Therefore, it is possible to prevent the pressing portion 15A from being plastically deformed.

すなわち、仮に、押圧部１５Ａがロック部材１２と同一側に位置していると、扉１を開く力により、押圧部１５Ａが塑性変形してしまう。押圧部１５Ａが塑性変形してしまうと、押圧部１５Ａで発生する弾性力、つまり凹部４の内面に圧接する力が減少する。 That is, if the pressing portion 15A is located on the same side as the lock member 12, the pressing portion 15A is plastically deformed by the force of opening the door 1. When the pressing portion 15A is plastically deformed, the elastic force generated by the pressing portion 15A, that is, the force that presses against the inner surface of the recess 4 is reduced.

このため、押圧部１５Ａがロック部材１２と同一側に位置する構成では、係止プレート１１を扉枠２に固定する固定力が低下してしまうおそれが高い。これに対して、本実施形態では、扉１を開く力により押圧部１５Ａが塑性変形してしまうことが防止される。 Therefore, in a configuration in which the pressing portion 15A is located on the same side as the lock member 12, there is a high possibility that the fixing force for fixing the locking plate 11 to the door frame 2 will decrease. On the other hand, in the present embodiment, the pressing portion 15A is prevented from being plastically deformed by the force of opening the door 1.

（第２実施形態）
上述の実施形態に係るバネ部１５は、１つの押圧部１５Ａを有する構成であった。これに対して、本実施形態に係る補助錠装置のバネ部１５（以下、バネ部１５０と記す。）は、図５に示されるように、２つの押圧部１５Ａを有する。 (Second Embodiment)
The spring portion 15 according to the above-described embodiment has a configuration having one pressing portion 15A. On the other hand, the spring portion 15 (hereinafter referred to as the spring portion 150) of the auxiliary lock device according to the present embodiment has two pressing portions 15A as shown in FIG.

以下の説明は、上述の実施形態に係る補助錠装置との相違点に関する説明である。なお、上述の実施形態と同一の構成要件等は、上述の実施形態と同一の符号が付されている。このため、本実施形態では、重複する説明は省略されている。 The following description is a description of the differences from the auxiliary lock device according to the above-described embodiment. The same configuration requirements and the like as those in the above-described embodiment are designated by the same reference numerals as those in the above-mentioned embodiment. Therefore, in this embodiment, duplicate explanations are omitted.

すなわち、本実施形態に係る押圧部１５Ａは、上下方向第１の向きにて凹部４の内面に圧接する第１押圧部１５Ａ１、及び上下方向第２の向きにて凹部４の内面に圧接する第２押圧部１５Ａ２にて構成されている。 That is, the pressing portion 15A according to the present embodiment has a first pressing portion 15A1 that presses against the inner surface of the recess 4 in the first vertical direction, and a first pressing portion 15A that presses against the inner surface of the recess 4 in the second vertical direction. It is composed of two pressing portions 15A2.

そして、バネ部１５０は、上下方向に変位可能に係止プレート１１に連結されている。具体的には、図６に示されるように、本実施形態に係る脱落規制部１３は、バネ部１５０及びバネ係止部１６等を有している。 The spring portion 150 is connected to the locking plate 11 so as to be displaceable in the vertical direction. Specifically, as shown in FIG. 6, the dropout control unit 13 according to the present embodiment has a spring unit 150, a spring locking unit 16, and the like.

バネ係止部１６は、バネ部１５０を上下方向に変位可能な状態で係止プレート１１に連結するための部材である。当該バネ係止部１６は、２つの接触片１５Ｂ及び係止部１５Ｄを有する。 The spring locking portion 16 is a member for connecting the spring portion 150 to the locking plate 11 in a vertically displaceable state. The spring locking portion 16 has two contact pieces 15B and a locking portion 15D.

このため、バネ係止部１６は、第１実施形態に係るバネ部１５と同様に、２つのボス部１５Ｃが対応する凹み部１４Ａに嵌り込み、かつ、係止部１５Ｄが係止プレート１１に係止された状態で、２つの接触片１５Ｂが２つの係止片１４を上下方向から挟み込むことにより係止プレート１１に固定される。 Therefore, the spring locking portion 16 is fitted into the recessed portion 14A to which the two boss portions 15C correspond to each other, and the locking portion 15D is fitted to the locking plate 11 as in the spring portion 15 according to the first embodiment. In the locked state, the two contact pieces 15B are fixed to the locking plate 11 by sandwiching the two locking pieces 14 from above and below.

各接触片１５Ｂには、バネ部１５０に設けられた長穴１５１に嵌り込む係止突起部１６Ａが少なくとも１つずつ設けられている。長穴１５１は、長径方向が上下方向と一致する貫通穴である。 Each contact piece 15B is provided with at least one locking protrusion 16A that fits into the elongated hole 151 provided in the spring portion 150. The elongated hole 151 is a through hole whose major axis direction coincides with the vertical direction.

そして、複数の係止突起部１６Ａそれぞれは、各長穴１５１に嵌り込んだ状態で上下方向にスライド可能である。このため、バネ係止部１６が係止プレート１１に固定された状態では、バネ部１５０は、係止プレート１１に対して上下方向に変位可能となる。 Each of the plurality of locking protrusions 16A can slide in the vertical direction while being fitted in each elongated hole 151. Therefore, in a state where the spring locking portion 16 is fixed to the locking plate 11, the spring portion 150 can be displaced in the vertical direction with respect to the locking plate 11.

したがって、本実施形態に係る補助錠装置では、利用者が係止プレート１１を扉枠２に固定する際に、ラッチボルト３の位置と貫通穴１１Ａの位置とを容易に合致させることが可能となる。 Therefore, in the auxiliary lock device according to the present embodiment, when the user fixes the locking plate 11 to the door frame 2, the position of the latch bolt 3 and the position of the through hole 11A can be easily matched. Become.

つまり、係止プレート１１が扉枠２に固定された後においても、利用者は、当該係止プレート１１を扉枠２に対して上下方向に変位させることができる。延いては、利用者は、ラッチボルト３の位置と貫通穴１１Ａの位置とを容易に合致させることが可能となる。 That is, even after the locking plate 11 is fixed to the door frame 2, the user can displace the locking plate 11 in the vertical direction with respect to the door frame 2. As a result, the user can easily match the position of the latch bolt 3 with the position of the through hole 11A.

（第３実施形態）
本実施形態は、第２実施形態の変形例である。すなわち、第２実施形態に係るバネ部１５０は、長穴１５１に嵌り込んだ係止突起部１６Ａにより、係止プレート１１に対して上下方向に変位可能となる構成であった。 (Third Embodiment)
