Description

本発明は、室内障子及び室外障子が共に閉鎖された状態で施錠が成されたかどうかを一目で確認可能とした空掛け防止クレセント錠に関する。 The present invention relates to an anti-hung crescent lock capable of confirming at a glance whether or not locking is achieved with both indoor and outdoor shojis closed.

従来より、引き違い窓等のサッシ用施錠装置としてクレセント錠が知られている。このクレセント錠は、図１６に示されるように、室内障子５４の縦框に取り付けられるベース部材５１と、このベース部材５１に対してクレセント軸５３を介して回動自在に取り付けられた笠金状のクレセント５２と、室外障子５５に取り付けられ前記クレセント５２が係合するためのフック部５６ａを有するクレセント受け金具５６とからなる施錠装置５０である（例えば、下記特許文献１等参照）。 Conventionally, a crescent lock is known as a locking device for a sash such as a sliding window. As shown in FIG. 16, the crescent lock has a base member 51 attached to the vertical shaft of the indoor shoji 54, and a cap metal shape attached to the base member 51 via a crescent shaft 53 so as to be rotatable. Of the crescent 52 and a crescent bracket 56 having a hook portion 56a attached to the outdoor shoji 55 and engaged with the crescent 52 (see, for example, Patent Document 1 below).

また、上記クレセント錠５０の場合は、内障子又は外障子が開放状態にあっても、クレセント５２を回動させることが可能であり、この施錠状態のまま障子を閉めると、外障子の縦框（召合せ框含む。）が室外側に突出したクレセント５２に衝突し、クレセントが変形したり損傷したりすることがある。これを防止するために、例えば下記特許文献２では、室内障子及び室外障子が共に閉鎖された状態にある時以外は、クレセント錠の操作レバーが施錠方向に回動できないようにした空掛け防止機能を備えたクレセント錠が提案されている。具体的に、内障子の召合せ框に操作レバーの回動により回動しつつ延出する掛け部を有するクレセント錠を設け、外障子の召合せ框に上記掛け部が係合するクレセント受けを設け、上記掛け部を含む回動側に揺動可能な揺動体を設け、この揺動体の一端を固定側に設けられた係止部に係止させて上記操作レバーの所定角度以上の回動を阻止すると共に、上記内障子と外障子が正常閉鎖位置にあるときに上記操作レバーの回動で上記揺動体の他端が上記クレセント受けもしくは外障子の召合せ框に当接する反力で上記揺動体の一端と係止部の係止状態を解除するようにしたクレセント錠が提案されている。 Further, in the case of the crescent lock 50, the crescent 52 can be rotated even when the inner or outer shoji is in an open state. (Including the summon bowl) may collide with the crescent 52 protruding to the outside of the room, and the crescent may be deformed or damaged. In order to prevent this, for example, in Patent Document 2 below, an anti-hanging function that prevents the operation lever of the crescent lock from rotating in the locking direction except when the indoor shoji and outdoor shoji are both closed. A crescent tablet with the following has been proposed. Specifically, a crescent lock having a hanging portion that extends while rotating by the rotation of the operation lever is provided on the summon child's summon cage, and a crescent receptacle that engages the above-mentioned hanging portion on the summon child's summon rod. Provided, a swingable swinging body is provided on the rotation side including the hook, and one end of the swinging body is locked to a locking part provided on the fixed side, so that the operation lever rotates more than a predetermined angle. And the other end of the oscillating body abuts on the crescent receptacle or the handbag of the outer arm by the rotation of the operation lever when the inner arm and the outer arm are in the normally closed position. A crescent lock has been proposed in which the locked state between one end of the rocking body and the locking portion is released.

また、本出願人も下記特許文献３において、クレセントを含む回動側に、クレセントの回動操作時に室内障子及び室外障子が正常に閉鎖されているならば、クレセント受け金具に一端側が当接するように揺動可能に作動部材を設けるとともに、前記操作レバー部分に、クレセント側に向けて付勢保持されるとともに、前記作動部材の他端側に形成された突部が係合する線状溝が形成された空掛け防止部材を設け、かつ前記ベース部材に対して前記空掛け防止部材の先端部が摺接する摺接部を形成するとともに、前記摺接部の中間部に前記空掛け防止部材の先端部が係合する係合段部を形成し、
前記クレセントの回動操作時に室内障子及び室外障子が正常に閉鎖されているならば前記作動部材の一端側がクレセント受け金具に当接し、引き続き操作レバーを回動させると、前記空掛け防止部材に形成された線状溝内を作動部材の突部が摺動することにより前記操作レバーの回動が許容されるとともに、前記空掛け防止部材が付勢力に抗して押し込まれると共に、作動部材が揺動することにより、前記空掛け防止部材の先端が前記係合段部に係合することなく回動され、前記室内障子及び室外障子が正常に閉鎖されていないならば、操作レバーの回動時に前記空掛け防止部材の先端が前記係合段部に係合することによりそれ以上の回動を阻止するようにしたクレセント錠を提案した。
特開平１１−９３４８８号公報特開平９−１５８５８４号公報特願２００４−４１１２１ In addition, in the following Patent Document 3, the applicant of the present invention also makes it so that one end of the crescent bracket is brought into contact with the pivot side including the crescent if the indoor and outdoor shojis are normally closed when the crescent is rotated. An operating member is provided on the operating lever portion so as to be swingable, and a linear groove that is urged and held toward the crescent side and engages with a protrusion formed on the other end side of the operating member. The formed anti-hanging member is formed, and a sliding contact portion is formed in which the tip portion of the emptying prevention member is in sliding contact with the base member, and the emptying prevention member is formed at an intermediate portion of the sliding contact portion. Forming an engaging step part with which the tip part is engaged;
If the indoor and outdoor shojis are normally closed during the turning operation of the crescent, the one end side of the actuating member comes into contact with the crescent bracket, and the operation lever is subsequently rotated to form the empty hanging prevention member. When the protrusion of the operating member slides in the linear groove, the operation lever is allowed to rotate, the emptying prevention member is pushed against the urging force, and the operating member is shaken. By moving, the tip of the anti-hanging member is rotated without being engaged with the engagement step portion, and if the indoor and outdoor shojis are not normally closed, A crescent lock has been proposed in which the tip of the anti-hanging member is engaged with the engagement step portion to prevent further rotation.

In this assembled state, the sliding contact portion 8c of the slider 8 is engaged with the first sliding contact portion 3c of the boss portion 3B.

次いで、本クレセント錠１における作動状態を図９及び図１０により説明する。図９(A)は室内障子及び室外障子が共に閉鎖された状態で施錠操作が成された場合（正常施錠時）のスライダー８の作動状態を示し、図９(B)は室内障子及び／又は室外障子が開かれた状態で施錠操作が成された場合（不正施錠時）のスライダー８の作動状態を示したものである。 Next, the operating state of the crescent lock 1 will be described with reference to FIGS. 9 and 10. FIG. 9A shows the operating state of the slider 8 when the locking operation is performed with both the indoor and outdoor shojis closed (normally locked), and FIG. 9B shows the indoor shoji and / or It shows the operating state of the slider 8 when the locking operation is performed in the state where the outdoor shoji is opened (during improper locking).

図９(A)に示す正常施錠の場合には、操作レバー６を回動させると、前記スライダーが付勢力に抗してスライド動作し、前記スライダー８先端の第２摺接係合部８ｄが第２摺接部３ｄ（乗上げ摺接部）に乗り上げた状態となる。この乗上げ状態では、スライダー８に形成されたマーカー部１２が操作レバー６に形成した窓部６ｃまで移動しており、操作レバー６を１８０度回動させた状態で、室内側から前記窓部６ｃを通してマーカー部１２が視認できるようになっている。一方、図９(B)に示す不正施錠の場合には、スライダー８先端の第１摺接係合部８ｃは第２摺接部３ｄに乗り上げることなく、回動終端まで第１摺動部３ｃに摺接し、スライダー８は位置不動とされ、操作レバー６を１８０度回動させた状態で、前記窓部６ｃにはマーカー部１２が現れないようになっている。 In the case of normal locking shown in FIG. 9A, when the operation lever 6 is rotated, the slider slides against the urging force, and the second sliding contact portion 8d at the tip of the slider 8 is moved. It will be in the state which got on the 2nd sliding contact part 3d (climbing sliding contact part). In this riding-up state, the marker portion 12 formed on the slider 8 has moved to the window portion 6c formed on the operation lever 6, and the window portion is viewed from the indoor side with the operation lever 6 rotated 180 degrees. The marker part 12 can be visually recognized through 6c. On the other hand, in the case of unauthorized locking shown in FIG. 9B, the first sliding contact portion 8c at the tip of the slider 8 does not ride on the second sliding contact portion 3d, and the first sliding portion 3c reaches the end of rotation. The slider 8 is fixed in position, and the marker portion 12 does not appear in the window portion 6c when the operation lever 6 is rotated 180 degrees.

以下、順に正常施錠時と、不正施錠時について、作動部材７とスライダー８との作動メカニズムについて詳述する。 Hereinafter, the operation mechanism of the operation member 7 and the slider 8 will be described in detail in the order of normal locking and unauthorized locking.

〈正常施錠時〉
図１０(A)は操作レバー６が下向きとなる解錠状態（図１参照）を示したものである。本ケースでは、室内障子及び室外障子が共に閉鎖された状態であるため、クレセント作動部材７の対向位置にはクレセント受け金具１１が定位している。 <Normal locking>
FIG. 10A shows an unlocked state (see FIG. 1) in which the operation lever 6 faces downward. In this case, since the indoor shoji and the outdoor shoji are both closed, the crescent metal fitting 11 is positioned at a position facing the crescent operating member 7.

この状態で、操作レバー６を徐々に回動させると、図１０(B)に示されるように、作動部材７の当接部７ｃがクレセント受け金具１１に当接する。前記当接部７ｃがクレセント受け金具１１に当接しても、前記スライダー８に形成された線状溝８ｂ内を作動部材７の突部７ｂが摺動することにより前記操作レバー６の回動が許容される。その後、引き続き操作レバー６を回動させると、作動部材７は僅かながら揺動しながら、スライダー８は徐々に付勢力に抗して押し込まれ、図１０(C)の状態でスライダー８先端の第２摺接係合部８ｄが第２摺接部３ｄに乗り上げた状態となる。その後は前記第２摺接係合部８ｄが第２摺接部３ｄに乗り上げた状態のまま、操作レバー６が回動操作され、最終的に操作レバー６が１８０°回動された図１０(G)の状態では、スライダー８が深部まで移動し、操作レバー６の窓部６ｃからマーカー部１２が視認可能な状態となって施錠が完了する。 In this state, when the operation lever 6 is gradually rotated, the contact portion 7c of the operating member 7 contacts the crescent bracket 11 as shown in FIG. Even if the abutting portion 7 c abuts the crescent receiving metal 11, the operating lever 6 is rotated by the projection 7 b of the operating member 7 sliding in the linear groove 8 b formed in the slider 8. Permissible. Thereafter, when the operation lever 6 is continuously rotated, the operating member 7 is slightly swung while the slider 8 is gradually pushed against the urging force, and in the state shown in FIG. The 2 slidable contact engaging portion 8d gets on the second slidable contact portion 3d. Thereafter, the operating lever 6 is rotated while the second sliding contact portion 8d is riding on the second sliding contact portion 3d, and finally the operating lever 6 is rotated 180 ° (FIG. 10). In the state of G), the slider 8 moves to the deep part, the marker part 12 is visible from the window part 6c of the operating lever 6, and locking is completed.

〈不正施錠時〉
一方、室内障子及び／又は室外障子が開かれた状態で施錠操作が成された場合には、前記作動部材７はクレセント受け金具１１に接触することはないため、操作レバー６の回動を阻害する要因がないため、スライダー８先端の第１摺接係合部８ｃは第２摺接部３ｄに乗り上げることなく、回動終端まで第１摺動部３ｃに摺接したまま回動されるため、作動部材７及びスライダー８に動作はなく、操作レバー６を１８０°回動させた状態では、操作レバー６の窓部６ｃにマーカー部１２は現れない。 <When illegally locked>
On the other hand, when the locking operation is performed in a state where the indoor shoji and / or the outdoor shoji are opened, the actuating member 7 does not come into contact with the crescent bracket 11, so that the operation lever 6 is prevented from rotating. Therefore, the first sliding contact portion 8c at the tip of the slider 8 does not ride on the second sliding contact portion 3d and is rotated while being in sliding contact with the first sliding portion 3c until the end of rotation. The actuating member 7 and the slider 8 do not operate, and the marker portion 12 does not appear in the window portion 6c of the operating lever 6 when the operating lever 6 is rotated 180 °.

〔第２形態例〕
次いで、図１１〜図１５に基づいて、本発明の第２形態例について詳述する。 [Second embodiment]
Next, a second embodiment of the present invention will be described in detail based on FIGS.

本クレセント錠１Ａにおいても、室内障子及び室外障子が共に閉鎖された状態にある時に施錠が成された場合、前記スライダー１３に設けられたマーカー部１２が、前記操作レバー６に形成された窓部６ｃを通し室内側から視認可能とした点は同様である。しかし、上記第１形態例では、スライダー８を作動部材７を介して移動させるようにしたのに対して、本第２形態例では、スライダー１３が直接クレセント受け金具１１に当接し、その反力により移動するようにした点で異なっている。 Also in this crescent lock 1A, when locking is performed when both the indoor shoji and outdoor shoji are closed, the marker portion 12 provided on the slider 13 is a window portion formed on the operation lever 6. The point which can be visually recognized from the indoor side through 6c is the same. However, in the first embodiment, the slider 8 is moved via the actuating member 7, whereas in the second embodiment, the slider 13 directly contacts the crescent bracket 11 and its reaction force It is different in that it is moved by.

以下、相違点を主に本クレセント錠１Ａについて具体的に詳述すると、
前記ベース部材３は、図１２及び図１３に示されるように、上記形態例とほぼ同様の構造を採用しているが、上記第１形態例では、第２摺接部３ｄを前記第１摺接部３ｃよりも低く形成したが、本第２形態例では同じ高さとした点で異なっている。 Hereinafter, the differences will be described in detail mainly regarding the present crescent lock 1A.
As shown in FIGS. 12 and 13, the base member 3 employs substantially the same structure as that of the above embodiment. However, in the above first embodiment, the second sliding contact portion 3 d is provided with the first sliding member. Although formed lower than the contact portion 3c, the second embodiment is different in that the height is the same.

また、クレセント５に関し、上記第１形態例では、操作レバー６の回動軸４をクレセント５の軸孔５ａに挿入するとともに、操作レバー６に形成された突部６ｂをクレセント５に形成された通孔５ｂに嵌合させることによって操作レバー６と一体的にクレセント５が回動するようにしたが、本第２形態例では、クレセント５の軸孔５ａを小判形状とするとともに、操作レバーの回動軸４の基端部を小判断面とすることにより、操作レバー６と一体的にクレセント５が回動するようにしている。 Further, regarding the crescent 5, in the first embodiment, the rotation shaft 4 of the operation lever 6 is inserted into the shaft hole 5a of the crescent 5, and the protrusion 6b formed on the operation lever 6 is formed on the crescent 5. Although the crescent 5 is rotated integrally with the operation lever 6 by being fitted into the through hole 5b, in the second embodiment, the shaft hole 5a of the crescent 5 is formed in an oval shape, and the operation lever 6 By using the base end portion of the rotating shaft 4 as a small judgment surface, the crescent 5 rotates integrally with the operation lever 6.

一方、前記スライダー１３は、詳細には図１４に示されるように、中間部に操作レバー６の回動軸４の基端部（楕円形状部）が挿通されるとともに、該スライダー１３が移動可能なように前記回動軸４の長径部よりも長径寸法の大きい軸孔部１３ａが形成された小片部材で、先端側には、クレセント受け金具１１と当接するとともに、摺接しながらクレセント受け金具１１を乗り越える当接摺動部１３ｂが形成されるとともに、下部側にはバネ設置部１３ｃが形成され、かつ一方側の側面にマーカー部１２が埋込み状態で設置されている。また、裏面側（ベース部材３側）の面には、ベース部材に形成された第１摺接部３ｃ、第２摺接部３ｄに対して摺接する摺接係合部１３ｄが形成されている。 On the other hand, as shown in detail in FIG. 14, the slider 13 has a base end portion (elliptical portion) of the rotation shaft 4 of the operation lever 6 inserted in the middle portion and the slider 13 is movable. In this way, a small piece member is formed with a shaft hole portion 13a having a larger diameter than the long diameter portion of the rotating shaft 4, and is in contact with the crescent receiving metal 11 at the distal end side, while being in sliding contact with the crescent receiving metal 11. Is formed on the lower side, and the marker portion 12 is installed in an embedded state on the side surface on one side. Further, on the surface on the back surface side (base member 3 side), there are formed sliding contact engaging portions 13d that are in sliding contact with the first sliding contact portion 3c and the second sliding contact portion 3d formed on the base member. .

前記クレセント錠１Ａの組立ては、図１２に示されるように、スライダー１３のバネ設置孔１３ｃ部にバネ部材９を嵌設するとともに、操作レバー６の回動軸４をスライダー１３の軸孔１３ａに挿入させるようにしながら、スライダー１３を操作レバー６の設置空間に嵌め込み、かつ操作レバー６の回動軸４をクレセント５の軸孔５ａに挿入するとともに、ベース部材３の軸孔３ｂに挿通し、裏面側において抜脱不能に止めるようにする。この組立て状態では、前記スライダー１３の摺接係合部１３ｄはボス部３Ｂの第１摺接部３ｃに対して係合している。 As shown in FIG. 12, the crescent lock 1 A is assembled by fitting the spring member 9 into the spring installation hole 13 c of the slider 13 and the rotation shaft 4 of the operation lever 6 into the shaft hole 13 a of the slider 13. While being inserted, the slider 13 is fitted into the installation space of the operation lever 6, and the rotation shaft 4 of the operation lever 6 is inserted into the shaft hole 5 a of the crescent 5, and inserted into the shaft hole 3 b of the base member 3, Try to keep it unremovable on the back side. In this assembled state, the sliding contact engaging portion 13d of the slider 13 is engaged with the first sliding contact portion 3c of the boss portion 3B.

次いで、本クレセント錠１Ａにおける作動状態を図１５により説明する。図１５は室内障子及び室外障子が共に閉鎖された状態で施錠操作が成された場合（正常施錠時）のスライダー１３の作動状態を示したものである。 Next, the operating state of the crescent lock 1A will be described with reference to FIG. FIG. 15 shows the operating state of the slider 13 when the locking operation is performed with both the indoor shoji and outdoor shoji closed (during normal locking).

同図に示されるように、操作レバー６を徐々に回動させると、図１５(B)に示されるように、スライダー１３の当接摺動部１３ｂがクレセント受け金具１１に当接する。引き続き操作レバー６を回動させると、スライダー１３は当接による反力により徐々に付勢力に抗して押し込まれ、図１５(F)の状態でスライダー１３の摺接係合部１３ｄが第２摺接部３ｄに乗り上げた状態となる。その後は前記摺接係合部１３ｄが第２摺接部３ｄに乗り上げた状態のまま、操作レバー６が回動操作され、最終的に操作レバー６が１８０°回動された図１５(G)の状態では、操作レバー６の窓部６ｃからマーカー部１２が視認可能な状態となって施錠が完了する。 As shown in FIG. 15, when the operation lever 6 is gradually rotated, the contact sliding portion 13 b of the slider 13 contacts the crescent receiving metal 11 as shown in FIG. When the operation lever 6 is continuously rotated, the slider 13 is gradually pushed against the urging force by the reaction force caused by the contact, and the sliding contact engaging portion 13d of the slider 13 is in the second state in the state of FIG. It will be in the state which got on the sliding contact part 3d. Thereafter, the operating lever 6 is rotated while the sliding contact engaging portion 13d is riding on the second sliding contact portion 3d, and finally the operating lever 6 is rotated 180 ° (G). In this state, the marker portion 12 is visible from the window portion 6c of the operation lever 6, and locking is completed.

一方、室内障子及び／又は室外障子が開かれた状態で施錠操作が成された場合には、前記スライダー１３はクレセント受け金具１１に接触することはないため、スライダー１３の移動はなく、操作レバー６を１８０°回動させた状態では、操作レバー６の窓部６ｃにマーカー部１２は現れない。 On the other hand, when the locking operation is performed in a state where the indoor shoji and / or the outdoor shoji are opened, the slider 13 does not come into contact with the crescent bracket 11, so that the slider 13 does not move and the operation lever In a state where 6 is rotated by 180 °, the marker portion 12 does not appear in the window portion 6 c of the operation lever 6.
