Description

本発明は、障子の戸先に設けられる錠受けガイド及び錠受けガイドを備えた建具に関するものである。   The present invention relates to a lock receiving guide provided at the door of a shoji and a fitting including the lock receiving guide.

引き違い窓等の建具には、戸先錠と称される施錠装置を備えたものが提供されている。施錠装置は、例えば、障子において戸先に位置する縦框に配設された施錠機構と、開口枠において戸先の縦框に対向する縦枠に配設された錠受けとによって構成されている。この施錠装置では、障子が閉じられた際に、縦框の戸先壁に形成した引込用開口を通じて錠受けが縦框の内部に進入し、やがて進入した錠受けが施錠機構に係合する。これにより、縦枠及び縦框の互いに離隔する移動が阻止され、開口枠に対して障子が閉じた状態に維持されることになる。錠受けと施錠装置との係合状態を解除すれば、障子を開けることが可能である(例えば、特許文献1参照)。   BACKGROUND ART Joiners such as sliding windows have been provided with a locking device called a door lock. The locking device is constituted by, for example, a locking mechanism disposed on a vertical shaft located at a door tip in a shoji, and a lock holder disposed on a vertical frame facing the vertical shaft of the door tip in an opening frame. . In this locking device, when the shoji is closed, the lock receiver enters the inside of the vertical fence through a pull-in opening formed in the wall of the vertical fence, and the lock receiver that has entered eventually engages the locking mechanism. As a result, the vertical frame and the vertical rod are prevented from moving apart from each other, and the shoji is kept closed with respect to the opening frame. If the engagement state between the lock receiver and the locking device is released, the shoji can be opened (see, for example, Patent Document 1).

この種の建具では、縦枠において障子の戸先面に対向する部位に突条が設けられる一方、障子に形成された引込用開口に錠受けガイドが装着され、障子を閉じた際に突条を錠受けガイドに当接させるようにしたものがある。錠受けガイドとしては、合成樹脂材によって成形されたものを適用するのが一般的である。こうした建具によれば、開口枠の突条に対して障子の錠受けガイドが当接することで、開口枠に対して障子の閉じた位置を正確に規定することが可能となる。従って、例えば開口枠の突条に対して障子の錠受けガイドが当接した時点で錠受けが施錠機構に係合するように構成すれば、施錠状態において障子がガタ付く事態を防止することができるようになる。   In this type of joinery, a ridge is provided in the vertical frame at the part facing the door end surface of the shoji, while a lock receiving guide is attached to the opening for retraction formed in the shoji, and the ridge when the shoji is closed. There are some which are made to contact the lock receiving guide. As the lock receiving guide, one formed by a synthetic resin material is generally applied. According to such a fitting, it is possible to accurately define the closed position of the shoji with respect to the opening frame by the lock receiving guide of the shoji coming into contact with the protrusion of the opening frame. Therefore, for example, if the lock receiver is configured to engage with the locking mechanism when the shoji lock guide comes into contact with the ridge of the opening frame, it is possible to prevent the shoji from rattling in the locked state. become able to.

しかしながら、縦框の戸先壁は、引込用開口が大きく切り欠かれたものであり、必ずしも十分な剛性を確保できるとはいえない。このため、大きな速度を持って障子を閉める等、開口枠の突条に対して障子の錠受けガイドが衝撃的に当接した場合には、縦框の戸先壁に損傷を来す恐れがある。   However, the doorside wall of the downpipe has a large opening for drawing-in, and it cannot always be said that sufficient rigidity can be secured.

More specifically, the lock receiving guide 40 has locking projections 41b and 41c at portions corresponding to the cover pieces 23e and 23f in the guide main body 41, and covers these locking projections 41b and 41c. By elastically engaging the engagement fins 23i and 23j of the pieces 23e and 23f, the pieces 23e and 23f are detachably attached to the door-end wall 23a.

ガイド本体41において縦枠13の突条13aに対向する部位には、受面41dが構成してある。受面41dは、突条13aの当接面13bに対して平行となるように形成した平面部分であり、戸先框23の戸先面23gから十分な肉厚を確保した位置に形成してある。この受面41dの位置は、突条13aの当接面13bが当接した時点で、引込用開口32に進入した錠受け31の係合孔31aに対して係合フック310のフック部312が進入し、係合フック310のフック部312が係合孔31aの係合面31bに当接した状態となるように設定してある。尚、図1の(b)に示すように、縦枠13の突条13aが受面41dに当接した場合には、カバー片23e,23fの先端と縦枠13の見込み面とが直接接触しないように間隙が確保してある。   A receiving surface 41d is formed in a portion of the guide body 41 facing the ridge 13a of the vertical frame 13. The receiving surface 41d is a flat portion formed so as to be parallel to the contact surface 13b of the protrusion 13a, and is formed at a position where a sufficient thickness is secured from the door-end surface 23g of the door-end rod 23. is there. The position of the receiving surface 41d is such that the hook portion 312 of the engaging hook 310 is engaged with the engaging hole 31a of the lock receiving member 31 that has entered the retraction opening 32 when the contact surface 13b of the protrusion 13a contacts. The hook portion 312 of the engagement hook 310 is set so as to be in contact with the engagement surface 31b of the engagement hole 31a. As shown in FIG. 1B, when the protrusion 13a of the vertical frame 13 comes into contact with the receiving surface 41d, the tips of the cover pieces 23e and 23f and the prospective surface of the vertical frame 13 are in direct contact. A gap is secured to prevent this.

支持受部42は、図4に示すように、それぞれガイド本体41の受面41dにおいて突条13aが当接する部分の延長上となる部位から突出した円柱状を成すもので、戸先框23に装着された状態において個々の先端面が支持壁23bに当接している。   As shown in FIG. 4, each of the support receiving portions 42 has a columnar shape that protrudes from a portion that is an extension of a portion of the receiving surface 41 d of the guide main body 41 against which the protrusion 13 a abuts. In the mounted state, the individual tip surfaces are in contact with the support wall 23b.

また、ガイド本体41において戸先面23gに対向する取付面41eには、窪部41fが設けてある。窪部41fは、戸先壁23aにおいて引込用開口32の外周縁となる部位に形成した凹部であり、錠受けガイド40が戸先框23に装着された状態において、ガイド本体41と戸先壁23aの切断端縁とが互いに接触するのを回避している。   In addition, a recess 41f is provided on the mounting surface 41e of the guide body 41 that faces the door end surface 23g. The recess 41f is a recess formed in a portion of the door-end wall 23a that becomes the outer peripheral edge of the pull-in opening 32. When the lock receiving guide 40 is mounted on the door-end ridge 23, the guide main body 41 and the door-end wall It is avoided that the cutting edge of 23a contacts each other.

上記のように構成した建具では、開口枠10に対して障子20が開いた状態にある場合、図1の(a)及び図2の(a)に示すように、施錠機構300の係合フック310が解錠バネ(図示せず)によって解錠位置に配置されている。障子20の戸先面23gに設けた錠受けガイド40は、戸先框23に構成した収容部23Hに収容され、カバー片23e,23fによってその大部分が覆われているため、室内側や室外側から容易に視認されることはなく、外観品質が著しく損なわれることはない。   In the joinery configured as described above, when the shoji 20 is in an open state with respect to the opening frame 10, as shown in FIG. 1A and FIG. 2A, the engagement hook of the locking mechanism 300. 310 is arranged at an unlocking position by an unlocking spring (not shown). The lock receiving guide 40 provided on the door-end surface 23g of the shoji 20 is accommodated in the accommodating portion 23H formed on the door-end fence 23, and most of the cover is covered with the cover pieces 23e, 23f. It is not easily seen from the outside, and the appearance quality is not significantly impaired.

この状態から障子20を閉めると、図1の(b)及び図2の(b)に示すように、縦枠13に設けた錠受け31が引込用開口32を通じて戸先框23の内部に進入され、縦枠13の突条13aがガイド本体41の受面41dに当接した時点で錠受け31の係合孔31aに係合フック310のフック部312が進入して係合面31bに当接した状態となるとともに、ラチェット320の係止部322がフック基部311に係止されて係合フック310の解錠位置への回転が阻止される。   When the shoji 20 is closed from this state, as shown in FIGS. 1 (b) and 2 (b), the lock 31 provided on the vertical frame 13 enters the interior of the door-toe 23 through the opening 32 for retraction. When the protrusion 13a of the vertical frame 13 comes into contact with the receiving surface 41d of the guide body 41, the hook portion 312 of the engaging hook 310 enters the engaging hole 31a of the lock receiver 31 and contacts the engaging surface 31b. At the same time, the locking portion 322 of the ratchet 320 is locked to the hook base portion 311 and the rotation of the engagement hook 310 to the unlocked position is prevented.

この状態においては、施錠機構300の係合フック310と縦枠13の錠受け31とが係合することにより、縦枠13及び戸先框23の互いに離隔する移動が阻止され、開口枠10に対して障子20が閉じた状態に維持される。しかも、縦枠13の突条13aが錠受けガイド40の受面41dに当接した時点で係合フック310が錠受け31の係合面31bに当接するため、開口枠10に対して障子20を開ける方向のみならず、障子20を閉める方向にも移動が阻止される。従って、施錠状態において障子20がガタ付く事態を招来する恐れもない。   In this state, the engagement hook 310 of the locking mechanism 300 and the lock receiver 31 of the vertical frame 13 are engaged to prevent the vertical frame 13 and the door-end rod 23 from moving apart from each other. On the other hand, the shoji 20 is kept closed. Moreover, since the engaging hook 310 contacts the engaging surface 31 b of the lock receiver 31 when the protrusion 13 a of the vertical frame 13 contacts the receiving surface 41 d of the lock receiving guide 40, the shoji 20 is applied to the opening frame 10. The movement is prevented not only in the direction of opening the door but also in the direction of closing the shoji 20. Therefore, there is no possibility of causing a situation in which the shoji 20 is loose in the locked state.

一方、この状態から図示せぬ解除レバー(図示せず)を操作すると、ラチェット320の係止部322がフック基部311から離隔され、解錠バネ(図示せず)のバネ力によって係合フック310が解錠位置に復帰するため、係合フック310のフック部312が錠受けガイド40の係合孔31aから逸脱され、開口枠10に対して障子20を開くことができるようになる。   On the other hand, when a release lever (not shown) (not shown) is operated from this state, the locking portion 322 of the ratchet 320 is separated from the hook base 311 and the engagement hook 310 is moved by the spring force of the unlocking spring (not shown). Accordingly, the hook portion 312 of the engagement hook 310 is deviated from the engagement hole 31a of the lock receiving guide 40, and the shoji 20 can be opened with respect to the opening frame 10.

ここで、開口枠10に対して障子20を閉めた場合には、縦枠13の突条13aが戸先框23に設けた錠受けガイド40の受面41dに当接することになるため、錠受けガイド40のガイド本体41に衝撃力が加えられる恐れがある。しかしながら、上述の建具によれば、錠受けガイド40のガイド本体41に支持受部42を設け、その先端面を戸先框23の支持壁23bに当接させるようにしている。従って、ガイド本体41に突条13aが当接した場合、ガイド本体41と戸先壁23aに作用する外力をガイド本体41の支持受部42を介して支持壁23bに伝えることができるようになり、錠受けガイド40を装着した戸先壁23aに大きな衝撃力が加えられる恐れがない。戸先框23の支持壁23bは、戸先壁23aのような引込用開口32が形成されておらず、大きな肉厚を確保せずとも十分な剛性を確保することが可能である。これにより、戸先壁23aの肉厚を大きくとることなく、戸先壁23aに損傷を来す恐れがなくなるため、製造コストや製品重量が増大する問題を抑えた上で、ガタ付くことなく障子20と開口枠10との間を施錠することが可能となる。   Here, when the shoji 20 is closed with respect to the opening frame 10, the ridge 13 a of the vertical frame 13 comes into contact with the receiving surface 41 d of the lock receiving guide 40 provided on the door rod 23. An impact force may be applied to the guide body 41 of the receiving guide 40. However, according to the joinery described above, the support receiving portion 42 is provided in the guide main body 41 of the lock receiving guide 40, and the front end surface thereof is brought into contact with the support wall 23 b of the door toe 23. Therefore, when the ridge 13a comes into contact with the guide body 41, an external force acting on the guide body 41 and the door wall 23a can be transmitted to the support wall 23b via the support receiving portion 42 of the guide body 41. There is no fear that a large impact force is applied to the door-end wall 23a on which the lock receiving guide 40 is mounted. The support wall 23b of the door toe wall 23 is not formed with the pull-in opening 32 like the door toe wall 23a, and it is possible to ensure sufficient rigidity without securing a large thickness. This eliminates the possibility of damaging the door wall 23a without increasing the wall thickness of the door wall 23a. It becomes possible to lock between 20 and the opening frame 10.

尚、上述した実施の形態では、ガイド本体41と支持受部42とを一体成形しているため、取り扱う場合の部品点数が増大することがないが、ガイド本体41と支持受部42とを別体に成形しても構わない。また、支持受部42は、図4に示すように、戸先框23に装着された状態において個々の先端面が支持壁23bに当接しているが、例えば、障子20が開いた状態において支持受部42の個々の先端面が支持壁23bに離間し、障子20が閉じた場合に支持受部42の個々の先端面が支持壁23bに当接する構成としても良い。   In the above-described embodiment, the guide main body 41 and the support receiving portion 42 are integrally formed. Therefore, the number of parts when handling is not increased, but the guide main body 41 and the support receiving portion 42 are separated. It may be formed into a body. Further, as shown in FIG. 4, the support receiving portion 42 is in contact with the support wall 23 b in a state in which each tip end surface is attached to the door toe 23. For example, the support receiving portion 42 is supported in a state in which the shoji 20 is open. The individual tip surfaces of the receiving portion 42 may be separated from the support wall 23b, and the individual tip surfaces of the support receiving portion 42 may abut against the support wall 23b when the shoji 20 is closed.

さらに、上述した実施の形態では、錠受けガイド40が戸先壁23aに取り付けられた状態において、ガイド本体41の戸先壁23aに対向する面と戸先壁23aとが当接したものを例示しているが、本発明はこれに限定されず、例えば、ガイド本体41の戸先壁23aに対向する面と戸先壁23aとを離間しても設けても良い。この場合、錠受けガイド40は、ガイド本体41の係止突起41b,41cをカバー片23e,23fの係合ヒレ23i,23jに対して弾性的に係合させるだけ戸先壁23aに装着することができる。この状態において、ガイド本体41に開口枠10の突条13aが当接した場合、ガイド本体41のみに外力が作用し、さらにこの外力が支持受部42を介して支持壁23bに作用することになる。このため、ガイド本体41に作用した外力が戸先框23の戸先壁23aに加えられることがなく、戸先壁23aに変形を来す恐れがない。   Furthermore, in embodiment mentioned above, in the state in which the lock receiving guide 40 was attached to the door-end wall 23a, what the surface facing the door-end wall 23a of the guide main body 41 and the door-end wall 23a contacted is illustrated. However, this invention is not limited to this, For example, you may provide even if the surface facing the door-end wall 23a of the guide main body 41 and the door-end wall 23a are spaced apart. In this case, the lock receiving guide 40 is mounted on the door-end wall 23a so that the locking protrusions 41b and 41c of the guide body 41 are elastically engaged with the engagement fins 23i and 23j of the cover pieces 23e and 23f. Can do. In this state, when the protrusion 13a of the opening frame 10 comes into contact with the guide body 41, an external force acts only on the guide body 41, and this external force acts on the support wall 23b via the support receiving portion 42. Become. For this reason, the external force which acted on the guide main body 41 is not applied to the door-end wall 23a of the door-end fence 23, and there is no possibility that the door-end wall 23a will be deformed.

また、上述した実施の形態では、支持壁23bとして框の外表面を構成するものを例示しているが、例えば、框の内部に支持壁23bに相当する内壁が存在するのであれば、その内壁を支持壁として構成することも可能である。   In the above-described embodiment, the support wall 23b is exemplified as one that constitutes the outer surface of the ridge. For example, if an inner wall corresponding to the support wall 23b exists in the heel, the inner wall Can also be configured as a support wall.

さらに、上述した実施の形態では、縦枠13と縦框23との間に施錠装置を設けるものを例示しているが、本発明はこれに限定されない。例えば、開口枠10に対して障子20が上下にスライドする建具に適用する場合には、下枠12と下框22との間もしくは上枠11と上框21との間に施錠装置を設けることも可能である。   Furthermore, in embodiment mentioned above, although what has provided a locking device between the vertical frame 13 and the vertical rod 23 is illustrated, this invention is not limited to this. For example, when applied to a joinery in which the shoji 20 slides up and down with respect to the opening frame 10, a locking device is provided between the lower frame 12 and the lower rod 22 or between the upper frame 11 and the upper rod 21.
