Description
本発明は、引き戸の施錠機構に関する。 The present invention relates to a sliding door locking mechanism.
従来の施錠機構付きの引き戸は、把手と施錠機構とが独立していたため、施錠するには、引き戸を閉めた後、把手から手を離して施錠機構を別に操作する必要があった。このような施錠操作は、特に高齢者、障害者、車椅子利用者等にとって不便であった。
特許文献１には、窓の引き戸に関し、引手の先端側を、引手の基端部を支点として回転可能とし、引手の引っ張り動作に連動して、引き戸の竪カマチを窓枠に施錠したり解錠するようにした施錠手段を設けた引き戸が記載されている。しかし、特許文献１の引き戸は、引手を強く引っ張る必要があったり、引手の操作性が悪かったりして、高齢者、障害者、車椅子利用者等が操作し易いものではなかった。
Since the conventional sliding door with a locking mechanism is independent of the handle and the locking mechanism, it is necessary to operate the locking mechanism separately after closing the sliding door and then releasing the hand from the handle. Such a locking operation is particularly inconvenient for elderly people, disabled people, wheelchair users and the like.
In Patent Document 1, regarding the sliding door of a window, the leading end side of the pulling handle can be rotated with the proximal end portion of the pulling handle as a fulcrum, and the sliding door's heel camchi is locked to the window frame in conjunction with the pulling operation of the pulling handle. A sliding door provided with locking means adapted to be locked is described. However, the sliding door of Patent Document 1 is not easy to be operated by an elderly person, a disabled person, a wheelchair user or the like because it is necessary to pull the handle strongly or the operability of the handle is poor.
本発明の目的は、引き戸の閉め始めから施錠までの動作及び解錠から引き戸を開けるまでの動作を、それぞれ、把手から手を離すことなく一連の動作としてスムーズに行うことができ、しかも、それぞれの一連の動作を強い力を要さずに容易に行うことのできる引き戸の施錠機構を提供することにある。 The object of the present invention is to smoothly perform the operation from the start of the sliding door to the locking and the operation from the unlocking to the opening of the sliding door as a series of operations without releasing the hand from the handle, respectively. It is an object of the present invention to provide a sliding door locking mechanism capable of easily performing a series of operations without requiring a strong force.

係合部材４は、略鎌形の形状を有し、その一端部が、引き戸２の開口枠７に設けた被係合部７１に係合する係合部４１を構成している。係合部材４の他端部４３は、図３に示すように、引き戸２の内部に固定された支持部材４４に回動可能に連結されており、係合部材４は、支持部材４４との連結部を支点（回動軸）として回動可能である。係合部材４は、出入口２０の開口枠７における、引き戸２の端面（閉方向側の一端面２４）対向部に設けた被係合部７１に、係合部４１が引っ掛かるように構成されている。 The engaging member 4 has a substantially sickle shape, and one end thereof constitutes an engaging portion 41 that engages with an engaged portion 71 provided in the opening frame 7 of the sliding door 2. As shown in FIG. 3, the other end portion 43 of the engagement member 4 is rotatably connected to a support member 44 fixed inside the sliding door 2, and the engagement member 4 is connected to the support member 44. The connecting portion can be turned as a fulcrum (turning shaft). The engaging member 4 is configured such that the engaging portion 41 is caught by the engaged portion 71 provided on the end portion (one end surface 24 on the closing direction side) of the sliding door 2 in the opening frame 7 of the doorway 20. Yes.
図１及び図４に示すように、本実施形態における把手３は、引き戸２を開いた状態においては、鉛直方向（上下方向）に直立しており、その状態から回動しないように維持されている。本実施形態の施錠機構は、引き戸２が開いた状態においては、把手３の回動を阻止し、引き戸２が閉じた状態においては、把手３の回動を許容するロック機構を備えている。 As shown in FIGS. 1 and 4, the handle 3 in the present embodiment stands upright in the vertical direction (up and down direction) when the sliding door 2 is opened, and is maintained so as not to rotate from that state. Yes. The locking mechanism of the present embodiment includes a lock mechanism that prevents the handle 3 from rotating when the sliding door 2 is open, and allows the handle 3 to rotate when the sliding door 2 is closed.
本実施形態におけるロック機構は、図４に示すように、引き戸２に、引き戸２の開閉時のスライド方向と平行な方向にスライド可能に設けられた棒状のロック部材６と、上記連結部材５のＬ字形の角部に形成された切り欠き部５１とからなる。ロック部材６は、直線状の棒状体の後端部に、下方に張り出した回動阻止用係合部６１を有している。図４に示すように、引き戸２が開いた状態におけるロック部材６は、引き戸２を閉める際の進行方向と同方向に前進して、回動阻止用係合部６１が切り欠き部５１の上縁部に密着しており、これにより、連結部材５及びそれに軸体３１を介して一体化された把手３が回動しないようになっている。 As shown in FIG. 4, the lock mechanism in the present embodiment includes a rod-like lock member 6 provided on the sliding door 2 so as to be slidable in a direction parallel to the sliding direction when the sliding door 2 is opened and closed, and the connecting member 5. It consists of a notch 51 formed in an L-shaped corner. The lock member 6 has a rotation preventing engagement portion 61 projecting downward at the rear end portion of the linear rod-shaped body. As shown in FIG. 4, the lock member 6 in a state in which the sliding door 2 is opened advances in the same direction as the moving direction when the sliding door 2 is closed, and the rotation preventing engagement portion 61 is located above the notch 51. In close contact with the edge, the connecting member 5 and the handle 3 integrated with the connecting member 5 via the shaft body 31 are prevented from rotating.
本実施形態の施錠機構による施錠を行うには、把手３を掴んで、引き戸２を、被係合部７１を形成した開口枠７に近づく方向（以下、閉方向ともいう）にスライドさせる。
引き戸２を閉方向にスライドさせると、図５に示すように、引き戸２の端面２４が開口枠７に当たる直前に、ロック部材６の先端部が開口枠７に突き当たり、その時点からロック部材６は、開口枠７に押されて後退する。
引き戸２の端面２４が開口枠７に突き当たると、図６に示すように、ロック部材６の回動阻止用係合部６１と、連結部材５に形成された切り欠き部５１との接触状態が解除され、連結部材５及び把手３の回動阻止状態が解除される。
In order to perform locking by the locking mechanism of the present embodiment, the handle 3 is grasped and the sliding door 2 is slid in a direction approaching the opening frame 7 in which the engaged portion 71 is formed (hereinafter also referred to as a closing direction).
When the sliding door 2 is slid in the closing direction, as shown in FIG. 5, immediately before the end surface 24 of the sliding door 2 hits the opening frame 7, the front end of the locking member 6 hits the opening frame 7, and from that point on, the locking member 6 Then, it is pushed back by the opening frame 7.
When the end surface 24 of the sliding door 2 hits the opening frame 7, as shown in FIG. 6, the contact state between the rotation preventing engagement portion 61 of the lock member 6 and the cutout portion 51 formed in the connecting member 5 is maintained. It is cancelled | released and the rotation prevention state of the connection member 5 and the handle 3 is cancelled | released.
把手３に、引き戸２をスライドさせた力をそのまま加えておくと、把手３の回動阻止状態が解除されることにより、把手３は、自然に、軸体３１を支点（回動軸）にして、開口枠７に近づく方向（反時計回り方向）に回動を開始し、それに連動して、連結部材５及びそれに連結された係合部材４が回動を開始する。そして、この係合部材４の回動により、図７に示すように、係合部材４の係合部４１が、開口枠７に設けた被係合部７１に係合して施錠が完了する。 If the force that caused the sliding door 2 to slide is applied to the handle 3 as it is, the handle 3 is released from the rotation prevention state, so that the handle 3 naturally uses the shaft body 31 as a fulcrum (rotating shaft). Then, the rotation starts in the direction approaching the opening frame 7 (counterclockwise direction), and in conjunction with this, the connecting member 5 and the engaging member 4 connected thereto start to rotate. Then, the rotation of the engaging member 4 causes the engaging portion 41 of the engaging member 4 to engage with the engaged portion 71 provided in the opening frame 7 as shown in FIG. .
この施錠の際には、把手３は、鉛直方向に直立した状態（図６に示す状態）から鉛直方向に対して約１５度の角度をなす状態（図７に示す状態）まで回動する。即ち、施錠の際の把手３の回動角度は約１５度である。これに対して、係合部材４は、図６及び図７に示すように、支持部材４４に連結部された下端部４３を支点（回転軸）にして約９０度回転する。このように、係合部材４を、把手３の回動角度より大きい角度回動させることにより、係合部材４による施錠を行う際の把手３の回動角度を小さく抑えることができ、そのため、引き戸２の閉め始めから施錠までの動作を、把手３から手を離すことなく一連の動作としてスムーズに行うことができる。 At the time of locking, the handle 3 rotates from a state standing upright in the vertical direction (state shown in FIG. 6) to a state forming an angle of about 15 degrees with respect to the vertical direction (state shown in FIG. 7). That is, the rotation angle of the handle 3 at the time of locking is about 15 degrees. On the other hand, as shown in FIGS. 6 and 7, the engaging member 4 rotates about 90 degrees with the lower end portion 43 connected to the support member 44 as a fulcrum (rotating shaft). Thus, by rotating the engagement member 4 by an angle larger than the rotation angle of the handle 3, the rotation angle of the handle 3 when locking by the engagement member 4 can be suppressed, and therefore The operation from the beginning of closing the sliding door 2 to the locking can be smoothly performed as a series of operations without releasing the hand from the handle 3.
尚、施錠の際の把手３の回動角度が大きい場合には、引き戸２が開口枠７に突き当たった後に、改めて力を入れ直して把手３を回動させる必要が生じたり、引き戸２を閉めた時点で、施錠されていないにも拘わらず、把手３から手を離してしまうといったことが起こり得る。即ち、引き戸２を閉める一連の動作として、係合部材４を回動させることが困難となる。 In addition, when the rotation angle of the handle 3 at the time of locking is large, after the sliding door 2 hits the opening frame 7, it becomes necessary to turn on the handle 3 again by applying force again, or the sliding door 2 is closed. At this point, it may happen that the hand is released from the handle 3 even though it is not locked. That is, it is difficult to rotate the engaging member 4 as a series of operations for closing the sliding door 2.
引き戸の閉め始めから施錠までの動作及び解錠から引き戸を開けるまでの動作を、それぞれ、把手から手を離すことなく一連の動作としてスムーズに行うことができるようにする観点から、施錠の際の把手の回動角度は３〜３０度であり、好ましくは５〜２０度、特に好ましくは５〜１５度である。また、同様の観点から、把手の回動角度に対する係合部材の回動角度の比は、１．５〜２０であることが好ましく、３〜１０であることがより好ましい。 From the point of view of enabling the operation from the beginning of closing the sliding door to locking and the operation from unlocking to opening the sliding door smoothly as a series of operations without releasing the handle, respectively, The rotation angle of the handle is 3 to 30 degrees , preferably 5 to 20 degrees, and particularly preferably 5 to 15 degrees. Further, from the same viewpoint, the ratio of the rotation angle of the engaging member to the rotation angle of the handle is preferably 1.5 to 20, and more preferably 3 to 10.
また、同様の観点から、把手３が鉛直方向（上下方向）に直立している状態（図１〜３に示す状態）を傾斜角度０度としたとき、引き戸２が開いた状態における把手３の傾斜角度は１０度以内であり、好ましくは５度以内であり、特に好ましくは０度である。傾斜角度という場合の傾斜の方向は、把手３の上端部が被係合部７１を形成した開口枠７に近づく方向又は開口枠７から遠ざかる方向の何れであっても良い。 Further, from the same viewpoint, when the state in which the handle 3 stands upright in the vertical direction (up and down direction) (the state shown in FIGS. 1 to 3) is set to an inclination angle of 0 degrees, the handle 3 in the state in which the sliding door 2 is opened. The inclination angle is within 10 degrees , preferably within 5 degrees, and particularly preferably 0 degrees. The direction of the inclination in the case of the inclination angle may be either the direction in which the upper end portion of the handle 3 approaches the opening frame 7 in which the engaged portion 71 is formed or the direction in which the handle 3 moves away from the opening frame 7.
本実施形態の施錠機構による施錠を解除するには、図８に示すように、把手３を、その先端部が被係合部７１を形成した開口枠７から離れる方向（時計回り方向，矢印Ｂ方向）に回動させる。これにより、連結部材５及び係合部材４が、施錠の際の回動方向とは反対方向に回動し、係合部材４の被係合部７１に対する係合状態が解除される。そして、把手３に、そのまま力を加え続けることにより、引き戸２は、被係合部７１を形成した開口枠７から遠ざかる方向（以下、開方向ともいう）にスライドする。
引き戸２が開口枠７から離れると、図９に示すように、コイルばね６３によって、被係合部７１が形成された開口枠７に向かう方向に付勢されているロック部材６が、開口枠７に向かう方向にスライドして、ロック部材６の回動阻止用係合部６１が、連結部材５の切り欠き部５１の上縁部に再び密着した状態となり、回動阻止用係合部６１が切り欠き部５１の上縁部に密着して、連結部材５及び把手３の回動が再び阻止される。
In order to release the locking by the locking mechanism of the present embodiment, as shown in FIG. 8, the handle 3 is moved away from the opening frame 7 in which the tip portion forms the engaged portion 71 (clockwise direction, arrow B). ). Thereby, the connecting member 5 and the engaging member 4 are rotated in the direction opposite to the rotating direction at the time of locking, and the engaged state of the engaging member 4 with respect to the engaged portion 71 is released. Then, by continuously applying force to the handle 3, the sliding door 2 slides in a direction away from the opening frame 7 in which the engaged portion 71 is formed (hereinafter also referred to as an opening direction).
When the sliding door 2 moves away from the opening frame 7, as shown in FIG. 9, the lock member 6 urged by the coil spring 63 in the direction toward the opening frame 7 in which the engaged portion 71 is formed, 7, the rotation preventing engagement portion 61 of the lock member 6 comes into close contact with the upper edge portion of the cutout portion 51 of the connecting member 5, and the rotation prevention engaging portion 61. Comes into close contact with the upper edge of the notch 51, and the rotation of the connecting member 5 and the handle 3 is prevented again.
上記の解錠の際には、把手３は、鉛直方向に対して約１５度の角度をなす状態（図７に示す状態）から鉛直方向に直立した状態（図８に示す状態）まで回動し、他方、係合部材４は、図７及び図８に示すように、支持部材に連結部された下端部４３を支点（回転軸）にして約９０度回転する。本実施形態においては、このように、係合部材４による施錠を解除（解錠）する際の把手３の回動角度も小さく抑えることができ、それにより、解錠から引き戸２を開けるまでの動作を、把手３から手を離すことなく一連の動作としてスムーズに行うことができる。 At the time of unlocking, the handle 3 is rotated from a state at an angle of about 15 degrees with respect to the vertical direction (state shown in FIG. 7) to a state upright in the vertical direction (state shown in FIG. 8). On the other hand, as shown in FIGS. 7 and 8, the engaging member 4 rotates about 90 degrees with the lower end portion 43 connected to the support member as a fulcrum (rotating shaft). In this embodiment, the rotation angle of the handle 3 at the time of releasing (unlocking) the locking by the engaging member 4 can also be reduced in this way, so that the process from unlocking to opening the sliding door 2 can be suppressed. The operation can be smoothly performed as a series of operations without releasing the hand from the handle 3.
本実施形態の引き戸の施錠機構によれば、このようにして、引き戸の閉め始めから施錠までの動作及び解錠から引き戸を開けるまでの動作を、それぞれ、把手から手を離すことなく一連の動作としてスムーズに行うことができ、しかも、それぞれの一連の動作を強い力を要さずに容易に行うことができる。そのため、高齢者、障害者、車椅子利用者等が操作し易い。
また、引き戸が開いている状態においては、ロック機構により、把手が動かないので安全である。更に、把手が傾いて施錠が完了するので、高齢者で視力が弱い人や、視覚障害者等にとっても、施錠及び解錠が直感的に確認できる。本発明の引き戸の施錠機構は、バリアフリー住宅に適している。
According to the locking mechanism of the sliding door of the present embodiment, in this way, the operation from the start of closing the sliding door to the locking and the operation from unlocking to opening the sliding door are each performed in a series without releasing the hand from the handle. In addition, each series of operations can be easily performed without requiring a strong force. Therefore, it is easy for an elderly person, a disabled person, a wheelchair user, etc. to operate.
Further, when the sliding door is open, the handle is not moved by the lock mechanism, which is safe. Furthermore, since the handle is tilted and locking is completed, locking and unlocking can be intuitively confirmed even for elderly people with weak visual acuity and visually impaired persons. The locking mechanism of the sliding door of the present invention is suitable for a barrier-free house.
以上、本発明の一実施形態について説明したが、本発明は、上記実施形態に制限されず、適宜変更可能である。
例えば、上記実施形態においては、把手３の回動方向と係合部材４の回動方向が同じであったが、両部材の回動方向は、図１０に示すように、逆方向であっても良い。図１０に示す例では、把手３と係合部材４とが、互いに噛み合う直径の異なる歯車５Ａ，５Ｂ（連結部材）からなる連結機構により連結されており、施錠の際及び解錠の際の何れにおいても、把手３と係合部材４とが逆方向（一方が時計回り方向、他方が反時計回り方向）に回動する。
As mentioned above, although one Embodiment of this invention was described, this invention is not restrict | limited to the said embodiment, It can change suitably.
For example, in the above embodiment, the turning direction of the handle 3 and the turning direction of the engaging member 4 are the same, but the turning directions of both members are opposite directions as shown in FIG. Also good. In the example shown in FIG. 10, the handle 3 and the engaging member 4 are connected by a connecting mechanism including gears 5A and 5B (connecting members) having different diameters that mesh with each other. The handle 3 and the engaging member 4 also rotate in the opposite direction (one is clockwise and the other is counterclockwise).
また、係合部材４は、回動により引き戸の開口枠に設けた被係合部に係合して、引き戸２が開かないようにできるものであれば、その形状や材質等は任意のものを用いることができる。例えば、係合部４１が棒状体の中間部等に形成されていても良いし、係合部４１の形状は、図１０に示すような半円形等、任意の形状とすることができる。 The engaging member 4 can have any shape, material, etc. as long as it can be engaged with an engaged portion provided in the opening frame of the sliding door by rotation to prevent the sliding door 2 from opening. Can be used. For example, the engaging part 41 may be formed in the middle part of the rod-like body, and the shape of the engaging part 41 can be an arbitrary shape such as a semicircular shape as shown in FIG.
また、上記実施形態においては、開口枠７に形成した窪みの開口周縁部に、係合部材挿入用の開口を設けた金属板７２を固定し、金属板７２の開口部の下縁部を被係合部７１として用いていたが、本発明における被係合部は、係合部材が回動して係合（掛合）し得るものであれば良く、例えば、開口枠に形成した窪み内、あるいは窪みの開口部付近に水平方向にバーを固定し、それを被係合部として用いることもできる。図１０には、断面半円形のバーを被係合部とした例が示されている。 In the above embodiment, the metal plate 72 provided with the opening for inserting the engaging member is fixed to the opening peripheral edge of the recess formed in the opening frame 7, and the lower edge portion of the opening of the metal plate 72 is covered. Although it was used as the engaging portion 71, the engaged portion in the present invention may be any member as long as the engaging member can be rotated and engaged (engaged), for example, in a recess formed in the opening frame, Alternatively, a bar can be fixed in the horizontal direction in the vicinity of the opening of the recess and used as the engaged portion. FIG. 10 shows an example in which a bar having a semicircular cross section is used as an engaged portion.
また、連結機構としては、係合部材４を、把手３の回動角度より大きな角度回動させ得る多様な構成のものを用いることができる。例えば、連結部材６を、直線状の棒状体として、係合部材４との連結部及び把手３との連結部をそれぞれ回動可能な連結部とし、係合部材４及び把手３それぞれの回転軸から離間した部位において、連結部材６をこれら両者にそれぞれ連結しても良い。 Further, as the coupling mechanism, various structures that can rotate the engagement member 4 by an angle larger than the rotation angle of the handle 3 can be used. For example, the connecting member 6 is a linear rod-like body, the connecting portion with the engaging member 4 and the connecting portion with the handle 3 are respectively rotatable connecting portions, and the respective rotating shafts of the engaging member 4 and the handle 3 are rotated. The connecting member 6 may be connected to both of them at a portion separated from the connecting member 6.
更に、連結機構は、図１０に示すように、互いに噛み合う直径の異なる歯車５Ａ，５Ｂからなるものであっても良い。図１０に示す例においては、把手３の一端部及び係合部材４の一端部がそれぞれ歯車に一体的に固定されており、把手３の回動に連動して、係合部材４が、把手３の回動角度より大きな角度回動する。また、把手３と係合部材４との間を３以上の歯車を介して連結することもできる。 Further, as shown in FIG. 10, the coupling mechanism may be composed of gears 5A and 5B having different diameters that mesh with each other. In the example shown in FIG. 10, one end of the handle 3 and one end of the engaging member 4 are integrally fixed to the gear, and the engaging member 4 is connected to the handle in conjunction with the rotation of the handle 3. The rotation angle is larger than the rotation angle of 3. Further, the handle 3 and the engaging member 4 can be connected via three or more gears.
また、ロック機構もその機能を実現し得る限り他方な構成のものを用いることができる。例えば、ロック部材の形状は、Ｌ字型、円弧状形等他の形状とすることができ、また、ロック部材の回動阻止用係合部の形状は、半円形、三角形、半円形状等任意の形状とすることができる。 In addition, the lock mechanism having the other configuration can be used as long as the function can be realized. For example, the shape of the lock member may be other shapes such as an L-shape or an arc shape, and the shape of the engagement member for preventing rotation of the lock member may be a semicircle, a triangle, a semicircle, or the like It can be of any shape.
また、ロック部材を、連結部材に係合させるのに代えて、係合部材や把手、更にその他の部分に係合させて、把手の回動を阻止するようにしても良い。また、ロック部材は、係合部材や把手（これらと一体化して回動する部材を含む）に設けた切り欠き部の他、係合部材や把手（これらと一体化して回動する部材を含む）に設けた孔や凹部等に係脱してこれらの回動を規制するものであっても良い。
また、上記実施形態のコイルばね６３に代えて、板ばね等の他の付勢手段を用いることもできる。更に、ロック機構は、省略することもできる。
また、本発明の施錠機構は、片引式、両引式、引き違い式の引き戸の他、蛇腹部分を伸縮して開閉する戸の施錠に用いることもできる。
Further, instead of engaging the lock member with the connecting member, the lock member may be engaged with an engagement member, a handle, or another portion to prevent the rotation of the handle. The lock member includes not only a notch portion provided in the engaging member and the handle (including a member that rotates integrally with these), but also the engaging member and the handle (a member that rotates together with these). ) May be engaged with or disengaged from a hole or a concave portion provided in () to restrict these rotations.
Moreover, it can replace with the coil spring 63 of the said embodiment, and can also use other urging means, such as a leaf | plate spring. Furthermore, the locking mechanism can be omitted.
Further, the locking mechanism of the present invention can be used for locking a door that opens and closes by expanding and contracting the bellows part, in addition to a single-drawing type, a double-drawing type, and a sliding type sliding door.
