特開2017−214745号公報JP, 2017-214745, A

上述した従来の開閉装置は、例えば、図19に示すように、開閉体3Zが、互いに隣り合う各パネルがヒンジ330を介して連結されて構成されており、開閉体3Zが閉鎖状態から開放状態に移動する際、又は、開閉体3Zが開放状態から閉鎖状態に移動する際において、開閉体3Zの移動方向に沿って互いに隣り合う上側に位置するパネル10Uの一方の領域側の面と下側に位置するパネル10Lの一方の領域側の面とのなす角度が180度以下となることが可能なように構成されている。
また、ガイドローラ300は、軸301と、軸301の先端に設けられたローラ302とを備えて構成される。
そして、このガイドローラ300のローラ302が、上下に隣り合う下のパネル10Lの左右の側縁から左右の外側に突出するように、軸301が、下のパネル10Lの左右の框305,305の上端側における一方の領域側の面に取付けられた軸受303によって回転可能に取付けられている。
この場合、ガイドローラ300の軸301は、軸301の安定な回転動作、又は、ガイドローラ300の安定な取付状態が維持されるように、軸301の後端側310が、軸受303を通過して左右の框305,305よりパネル10Lの中央側に突出するように設けられている。
また、補強体350は、上下に隣り合う上のパネル10Uの下端縁側における一方の領域側の面において、左右の框305,305間に亘って連続して設けられている。
従って、図19に示すように、開閉体3Zが閉鎖状態から開放状態に移動する際において、上のパネル10Uが開口側から天井側に移動する際に、補強体350が下のパネル10Lに近づくように回転した場合に、補強体350の下面351が下のパネル10Lに設けられた軸301の後端側310に衝突する可能性がある。又、開閉体3Zが開放状態から閉鎖状態に移動する際において、下のパネル10Lが天井側から開口側に移動する際に、下のパネル10Lに設けられた軸301の後端側310が上のパネル10Uに近づくように回転した場合に、軸301の後端側310が上のパネル10Uの補強体350に衝突する可能性がある。
このように、補強体350とガイドローラ300の軸301とが衝突した場合、衝突音の発生、補強体350の損傷、軸301や軸受303の損傷等の不具合が生じる可能性がある。
In the conventional opening / closing device described above, for example, as shown in FIG. 19, the opening / closing body 3Z is configured by connecting adjacent panels via a hinge 330, and the opening / closing body 3Z is opened to a closed state. When the open / close body 3Z moves from the open state to the closed state, the surface on one side and the lower side of the panel 10U located on the upper side adjacent to each other along the moving direction of the open / close body 3Z. It is configured such that the angle formed with the surface of the panel 10L located on one side of one region can be 180 degrees or less.
The guide roller 300 includes a shaft 301 and a roller 302 provided at the tip of the shaft 301.
Then, the shaft 301 of the left and right frames 305, 305 of the lower panel 10L is arranged so that the rollers 302 of the guide roller 300 project outward from the left and right side edges of the vertically adjacent lower panel 10L.

In this case, the shaft 301 of the guide roller 300 is such that the rear end side 310 of the shaft 301 passes through the bearing 303 so that the stable rotating operation of the shaft 301 or the stable mounting state of the guide roller 300 is maintained. The left and right frames 305, 305 are provided so as to project toward the center of the panel 10L.
Further, the reinforcing body 350 is continuously provided between the left and right frames 305, 305 on the surface of one region side on the lower edge side of the upper and lower adjacent panels 10U.
Therefore, as shown in FIG. 19, when the opening / closing body 3Z moves from the closed state to the open state, the reinforcing body 350 approaches the lower panel 10L when the upper panel 10U moves from the opening side to the ceiling side. When rotated like this, the lower surface 351 of the reinforcing body 350 may collide with the rear end side 310 of the shaft 301 provided on the lower panel 10L. Further, when the opening / closing body 3Z moves from the open state to the closed state, when the lower panel 10L moves from the ceiling side to the opening side, the rear end side 310 of the shaft 301 provided on the lower panel 10L is raised. The rear end side 310 of the shaft 301 may collide with the reinforcing body 350 of the upper panel 10U when the panel is rotated toward the panel 10U.
When the reinforcing body 350 and the shaft 301 of the guide roller 300 collide with each other in this manner, problems such as generation of collision noise, damage to the reinforcing body 350, damage to the shaft 301 and the bearing 303, and the like may occur.

Consists of board 69 The engaged portion that has been formed is an engaging portion on the extension end side that extends to one region 6 side of the upper reinforcing body 20, or an engaging portion on the extension end side that extends to one region 6 side of the lower reinforcing body 21. After the joint portion is set in a state of being sandwiched from three sides, the connecting plate 70 is fixed to the reinforcing plate portion 13a of the frame reinforcing member 13 by the fixing means such as the bolt 75 and the nut 76 (on one region 6 side of the panel). Surface).

即ち、補強体倒れ防止手段60は、一端側に設けられた連結部としての連結板70と、他端側に設けられた連結部としての被係合部とを備え、上側補強体20の一方の領域6側に延長する延長端側の係合部、又は、下側補強体21の一方の領域6側に延長する延長端側の係合部を、三方から囲んで挟持する被係合部が、引掛板63と押さえ板61と一方縁側補強板67及び他方縁側補強板69とにより構成されている。   That is, the reinforcement body collapse prevention unit 60 includes a connection plate 70 as a connection portion provided on one end side and an engaged portion as a connection portion provided on the other end side, and one side of the upper reinforcement body 20.

However, it is configured by the hook plate 63, the pressing plate 61, the one edge side reinforcing plate 67 and the other edge side reinforcing plate 69.

以上のように補強体倒れ防止手段60が設けられたことにより、補強体倒れ防止手段60は、以下のように、上側補強体20の倒れ、又は、下側補強体21の倒れを防止する。
即ち、例えば閉鎖状態の開閉体3に、開口2を隔てた他方の領域側から風圧が加わった場合、図5において、上側補強体20が上框15との境界を回転中心として上パネル10Aの中心10Zから離れる方向に、及び、下側補強体21が下框16との境界を回転中心として上パネル10Aの中心10Zから離れる方向に倒れようとするが、この際、補強体が倒れようとする力が引掛板63の接触面63aで受け止められて、補強体が倒れようとする力に対して補強体倒れ防止手段60が抵抗するため、補強体の倒れを防止できる。
また、例えば閉鎖状態の開閉体3に、開口を隔てた一方の領域6側から風圧が加わった場合、図5において、上側補強体20が上框15との境界を回転中心として上パネル10Aの中心10Z側に向けて、及び、下側補強体21が下框16との境界を回転中心として上パネル10Aの中心10Z側に向けて倒れようとするが、この際、補強体が倒れようとする力が一方縁側補強板67及び他方縁側補強板69の接触面72,72で受け止められて、補強体が倒れようとする力に対して補強体倒れ防止手段60が抵抗するため、補強体の倒れを防止できる。
Since the reinforcement body collapse prevention unit 60 is provided as described above, the reinforcement body collapse prevention unit 60 prevents the upper side reinforcement body 20 or the lower side reinforcement body 21 from collapsing as follows.
That is, for example, when wind pressure is applied to the open / close body 3 in the closed state from the other region side that separates the opening 2, in FIG. 5, the upper reinforcing body 20 rotates the boundary between the upper reinforcing body 20 and the upper frame 15 as the center of rotation of the upper panel 10A. The lower reinforcing body 21 tries to fall away from the center 10Z, and the lower reinforcing body 21 tends to fall away from the center 10Z of the upper panel 10A about the boundary with the lower frame 16 as a rotation center. The force that acts is received by the contact surface 63a of the hooking plate 63, and the reinforcement body collapse prevention unit 60 resists the force that the reinforcement body tends to collapse, so that the reinforcement body can be prevented from collapsing.
In addition, for example, when wind pressure is applied to the closed opening / closing body 3 from one side of the area 6 that separates the opening, in FIG. 5, the upper reinforcing body 20 rotates the boundary between the upper reinforcing body 20 and the upper frame 15 as the center of rotation of the upper panel 10A. Attempts to fall toward the center 10Z side and toward the center 10Z side of the upper panel 10A with the lower reinforcing body 21 as the center of rotation at the boundary with the lower frame 16 are attempted. Force is received by the contact surfaces 72, 72 of the one edge side reinforcement plate 67 and the other edge side reinforcement plate 69, and the reinforcement body collapse prevention means 60 resists the force of the reinforcement body to fall. Can prevent falling.

即ち、補強体とパネルの一方の領域6側の面とが補強体倒れ防止手段60で連結されたことにより、上側補強体20が上框15との境界を回転中心として開口2側に倒れてしまうことや、下側補強体21が下框16との境界を回転中心として開口2側に倒れてしまうことを防止でき、補強体の倒れに起因するパネルの変形を防止できるようになる。   That is, since the reinforcement body and the surface of the panel on one side of the region 6 are connected by the reinforcement body collapse prevention means 60, the upper reinforcement body 20 is tilted toward the opening 2 side around the boundary with the upper frame 15 as the rotation center. It is possible to prevent the lower side reinforcement body 21 from collapsing toward the opening 2 side around the boundary with the lower frame 16 as the center of rotation, and it is possible to prevent deformation of the panel due to the collapse of the reinforcement body.

尚、上側補強体20とパネルとを連結する場合と下側補強体21とパネルとを連結する場合とでは、同じ補強体倒れ防止手段60を向きを変えて使用する。
即ち、上側補強体20とパネルとを連結する場合においては、連結板70において他方縁側補強板69と対向する側の内面70uを框補強部材13の補強板部13aと接触させるとともに、傾斜板65の延長端縁65tと框補強部材13の主板部13xの板面とを対向させた状態としてから、連結板70を補強板部13aに取付ける。
また、下側補強体21とパネルとを連結する場合においては、連結板70において内面70uとは反対側の外面70fを框補強部材13の補強板部13aと接触させた状態としてから、連結板70を補強板部13aに取付ける。
Note that the same reinforcement collapse prevention means 60 is used in different directions when connecting the upper reinforcement 20 and the panel and when connecting the lower reinforcement 21 and the panel.
That is, when connecting the upper reinforcing body 20 and the panel, the inner surface 70u of the connecting plate 70 on the side facing the other edge side reinforcing plate 69 is brought into contact with the reinforcing plate portion 13a of the frame reinforcing member 13 and the inclined plate 65 is formed. The connecting plate 70 is attached to the reinforcing plate portion 13a after the extended edge 65t of the above and the plate surface of the main plate portion 13x of the frame reinforcing member 13 are opposed to each other.
Further, when connecting the lower reinforcing body 21 and the panel, after the outer surface 70f of the connecting plate 70 opposite to the inner surface 70u is brought into contact with the reinforcing plate portion 13a of the frame reinforcing member 13, the connecting plate is connected. 70 is attached to the reinforcing plate portion 13a.

The tip side inclined surface portion (tip side plate portion) 44f is formed so as to approach the other area side rolling surface 45a and extend in a direction away from the inclined connection plate portion 44d.

被ガイド部抜け防止手段8は、ローラ30がガイド部4のレール40の凹部42から抜けてしまうことを防止するための手段であり、例えば断面Z形状の長尺板により形成される。
被ガイド部抜け防止手段8は、他方領域側側板部45の他方領域側転動面45aを形成する板面とは反対側の板面と面接触する面接触板部81と、当該面接触板部81の一端81aより他方領域側側板部45の延長端縁45tを乗り越えて先端側傾斜面部44fに近付く方向に延長する抜け防止板部82と、面接触板部81の他端81bより抜け防止板部82の延長方向とは反対方向に延長して取付部41に取付けられる連結板部83とを備える。抜け防止板部82及び連結板部83は、面接触板部81の板面と直交する板面を有した平板により形成される。
連結板部83には、ボルト84を貫通させるボルト貫通孔83aが形成されている。
The guided portion slip-out prevention unit 8 is a unit for preventing the roller 30 from slipping out of the recess 42 of the rail 40 of the guide unit 4, and is formed of, for example, a long plate having a Z-shaped cross section.
The guided portion slip-out preventing means 8 includes a surface contact plate portion 81 that makes surface contact with a plate surface of the other area side plate portion 45 opposite to the plate surface forming the other area side rolling surface 45a, and the surface contact plate. The removal prevention plate portion 82 that extends from the one end 81a of the portion 81 over the extension edge 45t of the other region side plate portion 45 and extends in the direction approaching the tip side inclined surface portion 44f, and the removal prevention from the other end 81b of the surface contact plate portion 81. The connecting plate portion 83 is attached to the attaching portion 41 so as to extend in a direction opposite to the extending direction of the plate portion 82. The slip-out prevention plate portion 82 and the connecting plate portion 83 are formed by a flat plate having a plate surface orthogonal to the plate surface of the surface contact plate portion 81.
The connecting plate portion 83 is formed with a bolt through hole 83a through which the bolt 84 penetrates.

図12に示すように、取付部41の一方側固定板部41aには、ボルト46を貫通させるためのボルト貫通孔46a及びボルト84を貫通させるボルト貫通孔84aが形成されている。
従って、ボルト貫通孔46aに通したレール40のボルト46にナット47を締結することにより、レール40が一方側固定板部41aに固定される。
また、被ガイド部抜け防止手段8のボルト貫通孔83a及び一方側固定板部41aのボルト貫通孔84aに通したボルト84にナット85を締結することにより、被ガイド部抜け防止手段8が一方側固定板部41aに固定される。
As shown in FIG. 12, a bolt through hole 46 a through which the bolt 46 penetrates and a bolt through hole 84 a through which the bolt 84 penetrates are formed in the one side fixed plate portion 41 a of the mounting portion 41.
Therefore, by fastening the nut 47 to the bolt 46 of the rail 40 that has passed through the bolt through hole 46a, the rail 40 is fixed to the one side fixing plate portion 41a.
Further, by fastening the nut 85 to the bolt 84 that has passed through the bolt through hole 83a of the guided portion removal preventing means 8 and the bolt through hole 84a of the one side fixing plate portion 41a, the guided portion removal preventing means 8 can be moved to one side. It is fixed to the fixed plate portion 41a.

以下、各パネルに設けられた被ガイド部としてのローラ30をガイド部4により移動方向Sにガイドするガイド機構の構築方法の一例について説明する。
まず、構造物側取付部に図外の溶接やボルト及ナット等の固定手段を用いて取付部41の他方側固定板部41bを固定する。
次に、ボルト46及びナット47により、取付部41の一方側固定板部41aにレール40を固定する。
そして、このレール40の凹部42内にローラ30を挿入した後、ボルト84及びナット85により、取付部41の一方側固定板部41aに被ガイド部抜け防止手段8を取付ける。
即ち、被ガイド部抜け防止手段8の抜け防止板部82が、他方領域側側板部45の延長端縁45tを乗り越えて先端側傾斜面部44fに近付く方向に延長するように設けられるので、開閉体3に風圧が加わった場合等において、ローラ30が凹部42の開口を介して凹部42の外側に抜けようとしても、ローラ30が先端側傾斜面部44f及び抜け防止板部82に衝突するので、ローラ30が凹部42から外側に抜けないようになっている。
Hereinafter, an example of a method of constructing a guide mechanism that guides the roller 30 as a guided portion provided on each panel in the movement direction S by the guide portion 4 will be described.
First, the other-side fixing plate portion 41b of the mounting portion 41 is fixed to the structure-side mounting portion by using a welding means (not shown) or a fixing means such as a bolt and a nut.
Next, the rail 40 is fixed to the one side fixing plate portion 41a of the mounting portion 41 with the bolt 46 and the nut 47.
Then, after inserting the roller 30 into the recess 42 of the rail 40, the guided portion slip-out preventing means 8 is attached to the one side fixed plate portion 41a of the mounting portion 41 by the bolt 84 and the nut 85.
That is, since the removal prevention plate portion 82 of the guided portion removal prevention unit 8 is provided so as to extend in the direction of getting over the extended edge 45t of the other region side plate portion 45 and approaching the tip side inclined surface portion 44f, Even if the roller 30 tries to escape to the outside of the recess 42 through the opening of the recess 42 when the wind pressure is applied to the roller 3, the roller 30 collides with the tip-side inclined surface portion 44f and the slip-out prevention plate portion 82. The 30 does not come out from the recess 42 to the outside.

言い換えれば、ガイド部4に被ガイド部抜け防止手段8を取付けた状態では、抜け防止板部82及び先端側傾斜面部44fが邪魔になってローラ30をレール40の凹部42内に挿入できないように構成され、かつ、ガイド部4に被ガイド部抜け防止手段8が取付けられていない状態では、ローラ30をレール40の凹部42内に挿入できるように構成されている。
即ち、ガイド部4に被ガイド部抜け防止手段8が取付けられていない状態において、ローラ30をレール40の凹部42内に挿入した後に、被ガイド部抜け防止手段8をガイド部4に取付けることによって、抜け防止板部82及び先端側傾斜面部44fが邪魔になってローラ30が凹部42の外側に抜けることがないように構成されている。
In other words, in the state in which the guided portion removal preventing means 8 is attached to the guide portion 4, the removal preventing plate portion 82 and the tip side inclined surface portion 44f interfere so that the roller 30 cannot be inserted into the recess 42 of the rail 40. The roller 30 can be inserted into the concave portion 42 of the rail 40 when the guide portion 4 is not attached with the guided portion removal preventing means 8.
That is, in a state where the guided portion removal preventing means 8 is not attached to the guide portion 4, the guided portion removal preventing means 8 is attached to the guide portion 4 after the roller 30 is inserted into the recess 42 of the rail 40. The removal prevention plate portion 82 and the tip side inclined surface portion 44f are configured so as not to interfere with the roller 30 from coming out of the recess 42.

つまり、凹部42の開口となる他方領域側側板部45の延長端縁45tと先端側傾斜面部44fの先端44tとの間の間隔は、ローラ30の直径寸法よりも小さい寸法に設定されているが、ローラ30の中心軸を傾けながら当該ローラ30を凹部42の開口を介して凹部42内に挿入することが可能となっている。
そして、抜け防止板部82の先端82tと先端側傾斜面部44fの先端44tとの間の間隔dは、凹部42の開口となる他方領域側側板部45の延長端縁45tと先端側傾斜面部44fの先端44tとの間の間隔よりも小さい寸法に設定されるとともに、軸34の直径寸法よりも大きく設定されていて、ローラ30は、当該間隔dを介して凹部42内に挿入できず、また、当該間隔dを介して凹部42内から外側に外れることができないようになっている。
That is, the distance between the extended edge 45t of the other region side plate portion 45 that becomes the opening of the recess 42 and the tip end 44t of the tip end side inclined surface portion 44f is set to be smaller than the diameter dimension of the roller 30. It is possible to insert the roller 30 into the recess 42 through the opening of the recess 42 while inclining the central axis of the roller 30.
The distance d between the tip 82t of the slip-off preventing plate portion 82 and the tip 44t of the tip-side inclined surface portion 44f is set such that the extended edge 45t of the other region-side side plate portion 45 that forms the opening of the recess 42 and the tip-side inclined surface portion 44f. The roller 30 cannot be inserted into the recess 42 through the gap d because the gap is smaller than the distance between the tip 44t and the diameter of the shaft 34. , Cannot be disengaged from the inside of the recess 42 to the outside through the interval d.

また、上パネル10Aの下框16及び下側補強体21、中間パネル10Cの下框16及び下側補強体21は、下框16と下側補強体21とが一体に形成された一体成形品により構成されている。
また、軸受部33は、パネル構成体10を構成する各パネル10A,10B,10Cの、例えば、左縦框17及び右縦框18の上端縁側における一方の領域6側の面に取付けられている。例えば、図13に示すように、軸受部33は、ヒンジ32の下取付板32bと一体に形成されている。
また、図13に示すように、軸34の安定な回転動作、又は、ガイドローラ29の安定な取付状態が維持されるように、ガイドローラ29の軸34の後端34e側が、軸受部33を通過して、左縦框17又は右縦框18よりパネルの中央側に突出してパネル本体11の一方の領域6側に位置されるように設けられている。
従って、上下に隣り合うパネルにおいて、下のパネル10Lに設けられた軸34の後端34e側の真上にパネル10Uの下側補強体21が存在すると、上のパネル10Uが開口2側から天井側に移動する際に、上のパネル10Uがヒンジを31,32を介して回転して、上のパネル10Uの下側補強体21が下のパネル10Lに近づくように回転した場合、又は、下のパネル10Lが天井側から開口2側に移動する際に、下のパネル10Lがヒンジを31,32を介して回転して、下のパネル10Lの軸34の後端34e側が上のパネル10Uに近づくように回転した場合に、上のパネル10Uの下側補強体21における中空板部21aの下面と下のパネル10Lの軸34の後端34e側とが衝突する可能性がある(図19参照)。

Further, as shown in FIG. 13, the rear end 34e side of the shaft 34 of the guide roller 29 has the bearing portion 33 so that the stable rotation operation of the shaft 34 or the stable mounting state of the guide roller 29 is maintained. It is provided so as to pass through and project toward the center side of the panel from the left vertical frame 17 or the right vertical frame 18 and be located on one region 6 side of the panel body 11.
Therefore, in the vertically adjacent panels, when the lower reinforcing member 21 of the panel 10U is present immediately above the rear end 34e side of the shaft 34 provided in the lower panel 10L, the upper panel 10U is exposed from the opening 2 side to the ceiling. When the upper panel 10U rotates through the hinges 31 and 32 when moving to the side, and the lower reinforcing body 21 of the upper panel 10U rotates so as to approach the lower panel 10L, or When the panel 10L is moved from the ceiling side to the opening 2 side, the lower panel 10L rotates through the hinges 31 and 32, and the rear end 34e side of the shaft 34 of the lower panel 10L becomes the upper panel 10U. When rotated so as to approach, the lower surface of the hollow plate portion 21a in the lower reinforcing body 21 of the upper panel 10U may collide with the rear end 34e side of the shaft 34 of the lower panel 10L (see FIG. 19). ).

そこで、実施形態においては、下框16と下側補強体21とが一体に形成された一体成形品において、上のパネル10Uの下端側に設けられた下側補強体21の左右の端部を切除して、下のパネル10Lの上端側の左右の端部に設けられたガイドローラ29,29の軸34,34の後端34e,34e側の真上に、上のパネル10Uの下側補強体21の左右の端部が存在しないように構成したことによって、下側補強体20とガイドローラ29の軸34の後端34e側とが衝突しないように構成した。   Therefore, in the embodiment, in the integrally molded product in which the lower frame 16 and the lower reinforcing body 21 are integrally formed, the left and right end portions of the lower reinforcing body 21 provided on the lower end side of the upper panel 10U are provided. The upper panel 10U is reinforced on the lower side of the upper panel 10U just above the rear ends 34e, 34e of the shafts 34, 34 of the guide rollers 29, 29 provided on the left and right upper ends of the lower panel 10L. Since the left and right ends of the body 21 do not exist, the lower reinforcing body 20 and the rear end 34e side of the shaft 34 of the guide roller 29 do not collide.
