Description

本発明は、浴室や各居室の出入り口等に設けられる折戸、引き戸、開き戸などの建具に関する。   The present invention relates to a fitting such as a folding door, a sliding door, and a hinged door provided at the entrance of a bathroom or each living room.

従来、建具として、例えば、浴室と脱衣室との間に設置される折戸が提案されている(特許文献1参照)。この折戸は、浴室出入り口に設置される枠体と、この枠体内に配置される2枚の障子を備えた戸本体とを備えて構成されている。戸本体の吊元側、戸先側の縦框には、枠体に係合する上戸車および下戸車と、上戸車を操作する操作部材とが設けられている。このような折戸は、操作部材の操作によって上戸車を枠体から取り外し可能に構成されている。   Conventionally, as a fitting, for example, a folding door installed between a bathroom and a dressing room has been proposed (see Patent Document 1). The folding door includes a frame body installed at a bathroom doorway and a door body including two shojis arranged in the frame body. An upper door car and a lower door car engaged with the frame body and an operation member for operating the upper door car are provided on the vertical side of the door main body and the door side. Such a folding door is configured such that the upper door cart can be detached from the frame body by operation of the operation member.

特開2007−254977号公報JP 2007-254977 A

ところで、特許文献1に記載の折戸では、操作部材がコイルバネにより上方に付勢されることによって上戸車の位置決めを行っているだけであるため、枠体に対する戸本体の上下方向の遊び(隙間)の分だけコイルバネの付勢に抗して戸本体の上下動が可能である。   By the way, in the folding door of patent document 1, since the operation member is only biased upward by the coil spring and only the upper door is positioned, play in the vertical direction of the door body (gap) with respect to the frame body. Therefore, the door body can be moved up and down against the bias of the coil spring.

しかし、戸本体の開閉操作の際に枠体に対し大きな上下動が生じると、下戸車や上戸車が枠体から外れ、戸本体が脱落するおそれがある。
このような戸本体の脱落は、前述した折戸に限られず、引き戸や開き戸などの各種の建具においても同様に生じる可能性がある。
However, if a large vertical motion occurs with respect to the frame during the opening / closing operation of the door body, the lower door or upper door may come off the frame and the door body may fall off.
Such falling off of the door body is not limited to the folding door described above, and may occur in various fittings such as sliding doors and hinged doors.

本発明の目的は、枠体から着脱可能な障子の使用時における脱落を防止できる建具を提供することにある。   An object of the present invention is to provide a joinery that can prevent falling off when using a shoji detachable from a frame.

本発明の建具は、枠体と、前記枠体に開閉可能に取り付けられる障子とを備え、前記障子は、前記枠体に係合する係合位置および前記枠体への係合が解除される解除位置に移動可能な係合部材と、前記係合部材を前記係合位置および前記解除位置に移動操作可能な操作部材と、前記操作部材を案内可能に前記障子に形成された案内溝とを備え、前記案内溝は、前記操作部材の移動を規制する操作規制溝部と、前記操作部材の移動を可能とする操作可能溝部とを有して構成され、前記操作部材が前記操作規制溝部に位置する場合は、前記係合部材は前記係合位置から前記解除位置への移動が規制され、前記操作可能溝部は、前記障子の閉鎖移動中に、前記操作可能溝部に位置する前記操作部材が前記枠体に当接可能な位置に設けられることを特徴とする。   The joinery of the present invention includes a frame and a shoji attached to the frame so as to be openable and closable. The shoji is disengaged from the engagement position with the frame and the engagement with the frame. An engagement member that can be moved to a release position, an operation member that can move the engagement member to the engagement position and the release position, and a guide groove that is formed in the shoji so that the operation member can be guided. The guide groove is configured to include an operation restriction groove portion that restricts movement of the operation member and an operable groove portion that enables movement of the operation member, and the operation member is positioned in the operation restriction groove portion. In this case, the engagement member is restricted from moving from the engagement position to the release position, and the manipulable groove portion is configured so that the manipulating member positioned in the manipulable groove portion is closed during the closing movement of the shoji. It is provided at a position where it can contact the frame. To.

本発明によれば、操作部材を操作可能溝部に位置させることで、操作部材により係合部材を移動操作可能な状態となり、この操作部材の操作により係合部材を枠体に係合することによって障子を枠体に取り付けることができ、また、係合部材を枠体から係合解除することで障子を枠体から取り外すことができる。
他方、操作部材を操作規制溝部に位置させることで、操作部材により係合部材を移動操作不能な状態となり、障子の枠体に対する所定の取り付け状態を維持でき、障子の使用時における枠体からの脱落を防止できる。つまり、本発明では、操作部材を操作規制溝部に位置させることで係合部材を位置決めするため、障子の枠体に対する上下方向の遊び(隙間)があっても、障子の脱着可能な位置までの上下動を規制できる。このため、例えば折戸や引戸などにおいて、障子の開閉移動の際に、障子の枠体に対するかかり代を確保でき、障子の浮き上がりによる脱落を防止できる。
また、操作部材が操作可能溝部に位置した状態のまま障子を閉鎖移動させると、操作部材が枠体に干渉するため、容易には障子を閉鎖位置に位置させることはできない。このため、建具の施工における障子の動作確認などの際に、障子が着脱可能状態のままであるか否かを容易に確認できる。
さらに、建具の通常使用時において、障子が着脱可能状態のままでは障子を閉鎖位置に位置させにくくすることで、障子の操作者に障子が着脱可能状態のままであることの注意喚起を行うことができる。
According to the present invention, by positioning the operating member in the operable groove portion, the engaging member can be moved and operated by the operating member, and the engaging member is engaged with the frame body by operating the operating member. The shoji can be attached to the frame, and the shoji can be removed from the frame by disengaging the engaging member from the frame.
On the other hand, by positioning the operating member in the operation restricting groove portion, the engaging member cannot be moved and operated by the operating member, the predetermined attachment state of the shoji frame to the frame body can be maintained, and from the frame body when using the shoji Dropping can be prevented. In other words, in the present invention, since the engaging member is positioned by positioning the operating member in the operation restricting groove portion, even if there is play (gap) in the vertical direction with respect to the frame of the shoji, it is possible to reach the position where the shoji can be detached. Vertical movement can be regulated. For this reason, for example, in folding doors and sliding doors, when the shoji is opened and closed, it is possible to secure the allowance for the shoji frame and to prevent the shoji from falling off due to lifting.
Further, if the shoji is closed and moved while the operation member is positioned in the operable groove portion, the operation member interferes with the frame, so that the shoji cannot be easily positioned at the closed position. For this reason, it is possible to easily confirm whether or not the shoji is in a detachable state at the time of operation confirmation of the shoji in construction of the joinery.
In addition, during normal use of joinery, the shoji operator should be reminded that the shoji remains in a removable state by making it difficult to place the shoji in the closed position if the shoji remains in a removable state. Can do.

本発明の建具では、前記操作部材は、前記案内溝を覆う覆部を備え、前記覆部は、前記操作部材が前記操作規制溝部に位置した際には前記案内溝の全体を覆うとともに、前記操作部材が前記操作可能溝部に位置した際には前記案内溝の一部を露呈する構成とされることが好ましい。
このような構成によれば、操作部材が操作規制溝部に位置している場合、覆部により案内溝の全体を覆うことで、案内溝を目立たせることなく、シンプルな外観にできる。他方、操作部材が操作可能溝部に位置している場合、覆部から案内溝の一部が露呈されることで、外観上、案内溝の露呈部分を目立たせることができ、障子の取り付けや取り外しが可能な状態であることを容易に視認可能な状態にできる。
In the fitting according to the present invention, the operation member includes a cover portion that covers the guide groove, and the cover portion covers the entire guide groove when the operation member is positioned in the operation restriction groove portion. When the operation member is positioned in the operable groove portion, it is preferable that a part of the guide groove is exposed.
According to such a configuration, when the operating member is located in the operation restricting groove portion, the entire guide groove is covered by the cover portion, so that the guide groove can be made inconspicuous without making the guide groove conspicuous. On the other hand, when the operation member is located in the operable groove portion, the exposed portion of the guide groove can be conspicuous in appearance by exposing a part of the guide groove from the cover portion, and attaching and removing the shoji It is possible to make it easily visible that it is possible.

本発明の建具では、前記操作部材は、前記係合部材を上下方向に移動操作可能であり、前記操作規制溝部と前記操作可能溝部とは、上下方向に交差する方向において互いに隣接して配置されることが好ましい。
このような構成によれば、例えば障子が開閉操作時に上下方向に振動しても、この振動に起因して操作部材が上下方向に交差する方向に移動される可能性は低い。このため、前述した上下方向の振動があっても、操作部材が操作規制溝部から操作可能溝部に意図せずに移動してしまうおそれを低減できる。
In the joinery of the present invention, the operation member can move the engaging member in the vertical direction, and the operation restriction groove and the operable groove are arranged adjacent to each other in a direction intersecting the vertical direction. It is preferable.
According to such a configuration, for example, even if the shoji vibrates in the vertical direction during the opening / closing operation, there is a low possibility that the operation member is moved in the direction crossing the vertical direction due to the vibration. For this reason, even if there exists the vibration of the up-down direction mentioned above, a possibility that an operation member may unintentionally move from an operation control groove part to an operable groove part can be reduced.

本発明の建具では、前記操作規制溝部には、前記操作部材に係合可能な係合部が形成されることが好ましい。
このような構成によれば、操作部材を操作規制溝部から操作可能溝部に移動させる場合には、操作部材と係合部との係合を解除する必要がある。このため、前記係合を解除しない限り、操作部材を操作規制溝部に確実に位置させておくことができ、障子の枠体に対する取り付け状態を確実に維持できる。
In the joinery of the present invention, it is preferable that an engagement portion that can be engaged with the operation member is formed in the operation restriction groove portion.
According to such a configuration, when the operating member is moved from the operation restricting groove portion to the operable groove portion, it is necessary to release the engagement between the operating member and the engaging portion. For this reason, unless the said engagement is cancelled | released, an operation member can be reliably located in the operation control groove part, and the attachment state with respect to the frame of a shoji can be maintained reliably.

本発明の建具では、前記操作部材は、前記係合部材を上下方向に移動操作可能であり、前記係合部材は、上方への移動により前記枠体と係合可能であるとともに下方への移動により前記枠体との係合を解除可能に、前記障子の上端部に設けられ、前記障子は、前記枠体に対する前記係合位置に向けて前記係合部材を上方に付勢する付勢部材を備えることが好ましい。
このような構成によれば、付勢部材が係合部材を上方に付勢するため、操作部材が操作されない限り、係合部材は係合位置に位置する。このため、操作部材を手動操作しなくても、係合部材を枠体に押し当てることで付勢部材の弾性付勢力に抗して下方に移動させることができ、障子を枠体に簡単に取り付けることができる。
また、操作部材が操作可能溝部に位置している場合に障子を閉鎖移動すると、操作部材が枠体と干渉する。この際、操作者が操作部材と枠体とが干渉したことに気付かずに強い力で障子を閉鎖移動させてしまっても、操作部材は操作可能溝部から操作規制溝部へ横方向に移動するだけであり、障子や枠体などが破損するおそれをなくし得る。さらに、この障子の移動により操作部材を操作規制溝部に位置させることで、障子の使用時における脱落をも防止できる。
In the joinery of the present invention, the operation member can move the engagement member in the vertical direction, and the engagement member can be engaged with the frame body by moving upward and move downward. The urging member is provided at an upper end portion of the shoji so that the engagement with the frame can be released by the urging member, and the shoji urges the engagement member upward toward the engagement position with respect to the frame. It is preferable to provide.
According to such a configuration, since the urging member urges the engagement member upward, the engagement member is located at the engagement position unless the operation member is operated. For this reason, even if the operating member is not manually operated, it can be moved downward against the elastic biasing force of the biasing member by pressing the engaging member against the frame, and the shoji can be easily attached to the frame. Can be attached.
In addition, when the operating member is positioned in the operable groove portion and the shoji is closed and moved, the operating member interferes with the frame. In this case, even if the operator closes and moves the shoji with a strong force without noticing that the operation member and the frame have interfered, the operation member only moves laterally from the operable groove portion to the operation restriction groove portion. And can eliminate the risk of damage to the shoji and frame. Furthermore, the operation member is positioned in the operation restricting groove by the movement of the shoji, so that the omission during use of the shoji can be prevented.

本発明によれば、枠体から着脱可能な障子の使用時における脱落を防止できる建具を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the fitting which can prevent the drop-off at the time of use of the shoji which can be attached or detached from a frame can be provided.

次に、操作摘み53を横方向に操作して操作部材51を操作可能溝部562に位置させ、さらに操作摘み53を下方に操作して各上戸車30を図8に二点鎖線で示す位置まで下降する。つづいて、戸本体20を傾き状態から起き上がらせて枠体10に沿って立てた状態とし、各上戸車30をガイドレール14に係合する。
次に、操作摘み53を上方に操作して各上戸車30を図8に実線で示す位置まで上昇し、さらに操作摘み53を横方向に操作して操作部材51を操作規制溝部561に位置させ、戸本体20が枠体10から外れない状態とする。
この際、吊元側縦框23Aがガイドレール14,15に沿って移動しないように枠体10に取り付けられているか、戸先側縦框23Bがガイドレール14,15に沿って摺動可能に取り付けられているかを確認し、前述したように取り付けられていない場合には、各上戸車30の取り付け向きを変更する。
このようにして、戸本体20を枠体10に吊り込んで折戸1を形成する。
[Construction of this embodiment]
Hereinafter, an example of the hanging procedure of the door body 20 in the folding door 1 according to the present embodiment will be described. First, the door body 20 is lifted and inserted while being inclined obliquely with respect to the frame body 10, and the lower door carts 40 are engaged with the guide rails 15.
Next, the operation knob 53 is operated in the horizontal direction to position the operation member 51 in the operable groove 562, and the operation knob 53 is further operated downward to bring each upper door 30 to the position indicated by the two-dot chain line in FIG. Descend. Subsequently, the door body 20 is raised from the tilted state and is raised along the frame body 10, and each upper door cart 30 is engaged with the guide rail 14.
Next, the operation knob 53 is operated upward to raise each upper door 30 to the position indicated by the solid line in FIG. 8, and the operation knob 53 is operated laterally to position the operation member 51 in the operation restriction groove portion 561. The door main body 20 is assumed not to be detached from the frame body 10.
At this time, the suspension side vertical rod 23A is attached to the frame 10 so as not to move along the guide rails 14 and 15, or the door-end side vertical rod 23B is slidable along the guide rails 14 and 15. It confirms whether it is attached, and when it is not attached as mentioned above, the attachment direction of each upper door 30 is changed.
In this way, the door body 20 is suspended from the frame body 10 to form the folding door 1.

折戸1の形成後、戸本体20を開閉操作して戸本体20が枠体10に正常に取り付けられているか否かを確認する。具体的には、取手26または取手27の操作により、吊元側縦框23Aを中心として障子20Aを回転するとともに、戸先側縦框23Bを中心として障子20Bを回転しつつ、戸本体20を伸長し(閉鎖移動)、また、折りたたむ(開放移動)。
そして、戸本体20を閉鎖移動させた際に戸本体20を閉鎖位置(完全閉鎖位置)まで容易に閉鎖移動できるか否かを確認する。戸本体20を閉鎖位置まで容易に閉鎖移動できた場合には、操作部材51が左右両方とも操作規制溝部561に位置していることが確認できる。また、戸本体20を閉鎖位置まで容易に移動できなかった場合には、左右の一方または両方の操作摘み53が縦枠13の気密材13Aに干渉しており(図11参照)、操作部材51が操作可能溝部562に位置していることが確認できる。この場合には、操作部材51を操作して操作規制溝部561に位置させる。
このように戸本体20の取り付け状態を確認することで、折戸1の使用時に戸本体20が枠体10から脱落することを防止できる。
After the folding door 1 is formed, the door body 20 is opened and closed to check whether the door body 20 is normally attached to the frame body 10. Specifically, by operating the handle 26 or the handle 27, the shoji 20A is rotated around the suspension-side vertical rod 23A, and the door main body 20 is rotated while the shoji 20B is rotated around the door-end-side vertical rod 23B. Elongates (closed movement) and collapses (open movement).
Then, it is confirmed whether or not the door body 20 can be easily closed and moved to the closed position (completely closed position) when the door body 20 is closed and moved. When the door body 20 can be easily closed and moved to the closed position, it can be confirmed that the operation member 51 is positioned in the operation restriction groove portion 561 on both the left and right sides. When the door body 20 cannot be easily moved to the closed position, one or both of the left and right operation knobs 53 interfere with the airtight material 13A of the vertical frame 13 (see FIG. 11), and the operation member 51 It can be confirmed that is located in the operable groove 562. In this case, the operation member 51 is operated and positioned in the operation restriction groove portion 561.
Thus, by confirming the attachment state of the door main body 20, it is possible to prevent the door main body 20 from falling off the frame body 10 when the folding door 1 is used.

以下、戸本体20の枠体10からの取り外し手順の一例について説明する。先ず、操作摘み53を操作して操作部材51を操作可能溝部562に位置させ、さらに操作摘み53を下方に操作して各上戸車30を下降する。次に、戸本体20を持ち上げて各下戸車40をガイドレール15から外し、戸本体20を枠体10から抜き出す。このようにして、戸本体20を枠体10から取り外す。   Hereinafter, an example of a procedure for removing the door body 20 from the frame body 10 will be described. First, the operation knob 53 is operated to position the operation member 51 in the operable groove portion 562, and the operation knob 53 is further operated downward to lower each upper door 30. Next, the door main body 20 is lifted, each lower door carriage 40 is removed from the guide rail 15, and the door main body 20 is extracted from the frame body 10. In this way, the door body 20 is removed from the frame body 10.

[本実施形態の効果]
(1)操作部材51を操作可能溝部562に位置させることで、操作部材51により各上戸車30を上下方向に移動操作可能な状態とし、操作部材51の操作により各上戸車30を枠体10に係合することによって戸本体20を枠体10に取り付けることができる。また、各上戸車30を枠体10から係合解除することで戸本体20を枠体10から取り外すことができる。
他方、操作部材51を操作規制溝部561に位置させることで、操作部材51により各上戸車30を上下方向に移動操作不能な状態となり、戸本体20の枠体10に対する所定の取り付け状態を維持でき、戸本体20の使用時における枠体10からの脱落を防止できる。
また、操作部材51が操作可能溝部562に位置した状態のまま戸本体20を閉鎖移動させると、操作部材51が枠体10に干渉するため、容易には戸本体20を閉鎖位置に位置させることはできない。このため、折戸1の施工における戸本体20の開閉動作確認などの際に、戸本体20が着脱可能状態のままか否かを容易に確認できる。
さらに、折戸1の通常使用時において、戸本体20が着脱可能状態のままでは戸本体20を閉鎖位置に位置させにくくすることで、戸本体20の操作者に戸本体20が着脱可能状態のままであることの注意喚起を行うことができる。
[Effect of this embodiment]
(1) By positioning the operation member 51 in the operable groove portion 562, the upper door 30 can be moved up and down by the operation member 51, and each upper door 30 is operated by the operation member 51. The door body 20 can be attached to the frame body 10 by engaging with the frame body 10. Further, the door main body 20 can be detached from the frame body 10 by disengaging each upper door pulley 30 from the frame body 10.
On the other hand, by positioning the operation member 51 in the operation restriction groove portion 561, the operation member 51 makes it impossible to move the upper door 30 in the vertical direction, and a predetermined attachment state of the door body 20 to the frame body 10 can be maintained. Further, it is possible to prevent the door body 20 from dropping off from the frame body 10 during use.
Further, when the door main body 20 is closed and moved while the operation member 51 is positioned in the operable groove portion 562, the operation member 51 interferes with the frame body 10, and therefore the door main body 20 is easily positioned at the closed position. I can't. For this reason, it is possible to easily confirm whether or not the door main body 20 remains in a detachable state when checking the opening / closing operation of the door main body 20 in the construction of the folding door 1.
Furthermore, when the folding door 1 is normally used, the door body 20 remains detachable to the operator of the door body 20 by making it difficult to place the door body 20 in the closed position when the door body 20 remains detachable. Can be alerted to

(2)操作部材51が操作規制溝部561に位置した場合には、覆部52Aにより案内溝56の全体を覆うことで、案内溝56を外部から目立たせることなく、シンプルな外観にできる。
他方、操作部材51が操作可能溝部562に位置した場合には、覆部52Aから案内溝56の一部である操作規制溝部561が外部に露呈することで、外観上、案内溝56の露呈部分を目立たせることができ、戸本体20が着脱可能な状態のままであることを容易に視認可能な状態にでき、操作者への注意喚起ができる。
(3)戸本体20が開閉操作時に上下方向に振動しても、この上下方向の振動に起因して操作部材51が横方向に移動される可能性は低いため、当該振動に起因して操作部材51が操作規制溝部561から操作可能溝部562に意図せずに移動してしまうおそれを低減できる。
(2) When the operation member 51 is positioned in the operation restricting groove portion 561, the guide groove 56 is covered with the cover portion 52A, so that the guide groove 56 can be made to have a simple appearance without conspicuous from the outside.
On the other hand, when the operation member 51 is positioned in the operable groove portion 562, the operation restriction groove portion 561 that is a part of the guide groove 56 is exposed to the outside from the cover portion 52A, so that the exposed portion of the guide groove 56 is externally exposed. Can be made visible, and it can be easily visually recognized that the door main body 20 remains in a detachable state, and the operator can be alerted.
(3) Even if the door body 20 vibrates in the vertical direction during the opening / closing operation, the operation member 51 is unlikely to be moved in the lateral direction due to the vertical vibration. The possibility that the member 51 unintentionally moves from the operation restricting groove portion 561 to the operable groove portion 562 can be reduced.

[変形例]
なお、本発明は以上の実施形態で説明した構成のものに限定されず、本発明の目的を達成できる範囲での変形例は、本発明に含まれる。
例えば、前記実施形態では、操作部材本体52は、覆部52Aとして構成され、操作部材51が操作規制溝部561に位置した際に案内溝56の全面を覆うが、これに限定されず、案内溝56を覆わない構成であってもよい。
[Modification]
In addition, this invention is not limited to the thing of the structure demonstrated by the above embodiment, The modification in the range which can achieve the objective of this invention is contained in this invention.
For example, in the above-described embodiment, the operation member main body 52 is configured as the cover portion 52A, and covers the entire surface of the guide groove 56 when the operation member 51 is positioned in the operation restriction groove portion 561. The structure which does not cover 56 may be sufficient.

前記実施形態では、覆部52Aは、操作部材51が操作可能溝部562に位置した際に、案内溝56の操作規制溝部561を露呈させる程度の大きさ(横方向幅寸法)に形成されているが、これに限定されず、操作部材51が操作可能溝部562に位置した際においても、操作規制溝部561を露呈させることなく、案内溝56の全面を覆った状態を維持できる程度の大きさ(横方向幅寸法)に形成されていてもよい。   In the embodiment, the cover 52A is formed to have a size (lateral width dimension) that exposes the operation restricting groove 561 of the guide groove 56 when the operation member 51 is positioned in the operable groove 562. However, the present invention is not limited to this, and even when the operation member 51 is positioned in the operable groove portion 562, the size is such that the entire surface of the guide groove 56 can be maintained without exposing the operation restriction groove portion 561 ( (Width dimension in the horizontal direction).

前記実施形態では、操作機構50は、操作部材51と、案内溝56とを備えて構成されているが、これらの構成に加えて、例えば、図12に示すように、枠体10に対する係合位置に向けて上戸車30を上方に付勢する付勢部材である復帰バネ57(コイルばね)を備えていてもよい。
復帰バネ57は、係止軸部323に挿通され、係合筒部312の上面とフランジ322の下面との間に介在されている。
In the above-described embodiment, the operation mechanism 50 is configured to include the operation member 51 and the guide groove 56. In addition to these configurations, for example, as illustrated in FIG. A return spring 57 (coil spring), which is an urging member that urges the upper door 30 upward toward the position, may be provided.
The return spring 57 is inserted through the locking shaft portion 323 and is interposed between the upper surface of the engagement tube portion 312 and the lower surface of the flange 322.

このような復帰バネ57を備えている場合、復帰バネ57が各上戸車30を上方に付勢するため、操作部材51が操作されない限り、各上戸車30はガイドレール14との係合位置に位置する。このため、操作部材51を手動操作しなくても、各上戸車30を枠体10に押し当てることで復帰バネ57の弾性付勢力に抗して下方に移動させることができ、戸本体20を枠体10に簡単に取り付けることができる。
また、操作部材51が操作可能溝部562に位置している場合に戸本体20を閉鎖移動すると、操作部材51が枠体10の気密材13Aと干渉する。この際、仮に操作者が操作部材51と気密材13Aとの干渉に気付かずに強い力で戸本体20を閉鎖移動させてしまっても、復帰バネ57の弾性力により被案内部55が操作可能溝部562の上部側に位置しているため、操作摘み53が気密材13Aや気密材13Aが取り付けられた縦枠13の取付部に押し当てられ、操作部材51が操作可能溝部562の上部側から操作規制溝部561に向かって横方向に移動するだけである。このため、戸本体20や枠体10などが破損するおそれを低減できる。さらに、戸本体20の移動により操作部材51を操作規制溝部561に位置させることで、戸本体20の使用時における脱落をも防止できる。
When such a return spring 57 is provided, the return spring 57 biases each upper door 30 upward, so that each upper door 30 is in the engagement position with the guide rail 14 unless the operation member 51 is operated. To position. For this reason, even if the operation member 51 is not manually operated, each upper door 30 can be moved downward against the elastic biasing force of the return spring 57 by pressing the upper door 30 against the frame body 10. It can be easily attached to the frame 10.
Further, when the door body 20 is closed and moved when the operation member 51 is positioned in the operable groove portion 562, the operation member 51 interferes with the airtight material 13 </ b> A of the frame body 10. At this time, even if the operator closes and moves the door body 20 with a strong force without noticing the interference between the operation member 51 and the airtight member 13A, the guided portion 55 can be operated by the elastic force of the return spring 57. Since it is located on the upper side of the groove portion 562, the operation knob 53 is pressed against the mounting portion of the vertical frame 13 to which the airtight material 13A and the airtight material 13A are attached, and the operation member 51 is moved from the upper side of the operable groove portion 562. It only moves in the lateral direction toward the operation restricting groove 561. For this reason, a possibility that the door main body 20, the frame 10, etc. may be reduced can be reduced. Furthermore, the operation member 51 is positioned in the operation restricting groove 561 by the movement of the door body 20, so that the door body 20 can be prevented from falling off during use.

前記実施形態では、案内溝56は、操作規制溝部561と操作可能溝部562とを有して構成されているが、これらの構成に加えて、例えば図13(A)に示すように、操作部材51の操作可能溝部562への移動を規制する係合部である係合凹部563Aをさらに有していてもよい。
係合凹部563Aは、操作規制溝部561の下部に形成されている。係合凹部563Aの横方向幅寸法は、操作部材51の被案内部55の横方向幅寸法と略同じである。
係合凹部563Aが形成される場合、操作規制溝部561の横方向幅寸法は、係合凹部563Aの横方向幅寸法よりも若干大きくされる。このため、横方向において係合凹部563Aと操作可能溝部562との間には、被案内部55を係止可能な仕切り壁部が形成される。
このような係合凹部563Aは、操作規制溝部561に位置した操作部材51の自重に基づいて被案内部55と係合し、操作部材51の操作可能溝部562に向かう横方向の移動を規制する。係合凹部563Aと操作部材51との係合は、操作により操作部材51を若干上昇させることによって解除可能である。
このような係合凹部563Aに対し操作部材51の被案内部55が係合することで、操作部材51の操作可能溝部562に向かう横方向の移動を規制できる。そして、操作部材51を操作規制溝部561から操作可能溝部562に移動させる場合には、操作部材51と係合凹部563Aとの係合を解除する必要がある。このため、これらの係合を解除しない限り、操作部材51を操作規制溝部561に確実に位置させておくことができ、戸本体20の枠体10に対する取り付け状態を確実に維持できる。
In the above-described embodiment, the guide groove 56 is configured to include the operation restricting groove portion 561 and the operable groove portion 562. In addition to these configurations, for example, as illustrated in FIG. You may further have the engagement recessed part 563A which is an engaging part which regulates the movement to the operable groove part 562 of 51.
The engaging recess 563A is formed in the lower part of the operation restricting groove 561. The lateral width dimension of the engaging recess 563 </ b> A is substantially the same as the lateral width dimension of the guided portion 55 of the operation member 51.
When the engaging recess 563A is formed, the lateral width of the operation restricting groove 561 is slightly larger than the lateral width of the engaging recess 563A. For this reason, a partition wall portion capable of locking the guided portion 55 is formed between the engagement recess portion 563A and the operable groove portion 562 in the lateral direction.
Such an engagement concave portion 563A engages with the guided portion 55 based on the weight of the operation member 51 located in the operation restriction groove portion 561, and restricts the lateral movement of the operation member 51 toward the operable groove portion 562. . The engagement between the engagement recess 563A and the operation member 51 can be released by slightly raising the operation member 51 by an operation.
By engaging the guided portion 55 of the operating member 51 with such an engaging recess 563A, lateral movement of the operating member 51 toward the operable groove portion 562 can be restricted. And when moving the operation member 51 from the operation control groove part 561 to the operation possible groove part 562, it is necessary to cancel engagement with the operation member 51 and the engagement recessed part 563A. Therefore, as long as these engagements are not released, the operation member 51 can be reliably positioned in the operation restricting groove portion 561, and the attachment state of the door body 20 to the frame body 10 can be reliably maintained.

また、操作機構50が図12に示す前述した復帰バネ57を備えている場合には、係合凹部563Aに代えて、図13(B)に示す係合部である係合凹部563Bを備えていてもよい。
係合凹部563Bは、係合凹部563Aと概ね同様に構成されているが、操作規制溝部561の下部ではなく上部に逆向きに形成されている。この場合、操作規制溝部561の横方向幅寸法は、係合凹部563Bの横方向幅寸法よりも若干大きく形成される。このため、係合凹部563Bと操作可能溝部562との間には、被案内部55を係止可能な段部が形成される。
このような係合凹部563Bに対し、復帰バネ57によって上方に付勢される操作部材51の被案内部55が係合することで、操作部材51の操作可能溝部562に向かう横方向の移動を規制できる。そして、操作部材51を操作規制溝部561から操作可能溝部562に移動させる場合には、操作部材51と係合凹部563Bとの係合を解除する必要がある。このため、これらの係合を解除しない限り、操作部材51を操作規制溝部561に確実に位置させておくことができ、戸本体20の枠体10に対する取り付け状態を確実に維持できる。なお、係合凹部563Bと操作部材51との係合は、操作により操作部材51を若干下降させることによって解除可能である。
In addition, when the operation mechanism 50 includes the above-described return spring 57 shown in FIG. 12, an engagement recess 563B that is an engagement portion shown in FIG. 13B is provided instead of the engagement recess 563A. May be.
The engaging concave portion 563B is configured in substantially the same manner as the engaging concave portion 563A, but is formed in the opposite direction in the upper portion, not the lower portion of the operation restricting groove portion 561. In this case, the lateral width dimension of the operation restricting groove 561 is formed to be slightly larger than the lateral width dimension of the engaging recess 563B. For this reason, a step portion capable of locking the guided portion 55 is formed between the engaging recess portion 563B and the operable groove portion 562.
When the guided portion 55 of the operation member 51 urged upward by the return spring 57 is engaged with such an engagement recess 563B, the lateral movement toward the operable groove portion 562 of the operation member 51 is performed. Can be regulated. And when moving the operation member 51 from the operation control groove part 561 to the operation possible groove part 562, it is necessary to cancel engagement with the operation member 51 and the engagement recessed part 563B. Therefore, as long as these engagements are not released, the operation member 51 can be reliably positioned in the operation restricting groove portion 561, and the attachment state of the door body 20 to the frame body 10 can be reliably maintained. The engagement between the engagement recess 563B and the operation member 51 can be released by slightly lowering the operation member 51 by an operation.
