ものである。The canopy opening/closing device according to the present invention is used, for example, as a storage device for a ceiling ladder leading to the ceiling space, as shown in FIGS. 3 and 4.
is folded and attached, and when canopy 1 is opened, ladder 2
The ladder 2 is extended between the floor 3 and the attic 4.
天蓋１は矩形状となり、後縁を天井５に穿設した開口部
６の後端縁に蝶番７にて取付けられる。The canopy 1 has a rectangular shape, and its rear edge is attached to the rear edge of an opening 6 formed in the ceiling 5 with a hinge 7.
開口部６周縁上面には補強根太８及び枠板９が取付けら
れ、開口部６周縁下面には額縁１０が取付けられる。A reinforcing joist 8 and a frame plate 9 are attached to the upper surface of the periphery of the opening 6, and a picture frame 10 is attached to the lower surface of the periphery of the opening 6.
天蓋１の上面の両側の略中夫には第１のリンク金具１１
の下端が夫々垂直方向に回動自在に枢支しである。First link metal fittings 11 are installed approximately on both sides of the upper surface of the canopy 1.
The lower ends of each are pivotably supported in a vertical direction.
これらの両側の第１のリンク金具１１は上端を第２のリ
ンク金具１２に枢軸８にて垂直方向に回動自在に枢支さ
れている。The upper ends of the first link fittings 11 on both sides are pivotally supported by the second link fittings 12 about a pivot 8 so as to be freely rotatable in the vertical direction.
第２のリンク金具１２の上端は開口部６の周内側面の中
央部に垂直方向に回動自在に枢支され、天蓋１の開閉に
より第１のリンク金具１１とともに伸展乃至は折畳み回
動するようになっている。The upper end of the second link fitting 12 is rotatably supported in the vertical direction at the center of the inner circumferential surface of the opening 6, and extends or folds and rotates together with the first link fitting 11 when the canopy 1 is opened or closed. It looks like this.
これらの第２のリンク金具１２の上端の枢軸部１３の近
傍の開口部６の内側面には第２のリンク金具１２の回動
を規制するストッパ金具１４が固設せられている。A stopper fitting 14 for restricting rotation of the second link fittings 12 is fixed on the inner surface of the opening 6 near the pivot portion 13 at the upper end of these second link fittings 12 .
即ちストッパ金具１４は開口部６の内側面に斜交いに基
板１５を固定するとともに基板１５に突片２２を突設し
、この突片２２に穿孔した孔に１字型のストッパ片１７
の上端に下端を固定したボルト１９を挿通し、突片２２
の両側でボルト１９に螺合したナツト１６にて突片２２
にストッパ片１７を固定したもので第２図のように天蓋
１を開成すると、第２のリンク金具１２が枢軸部１３を
中心として下方向に回動した際に第２のリンク金具１２
の上端下縁がストッパ片１７下端のＵ字溝１７ ａ内に
嵌まって係合し、第２のリンク金具１２の所定角度以上
の回動を規制するわけである。That is, the stopper metal fitting 14 fixes the board 15 diagonally to the inner surface of the opening 6, and has a protruding piece 22 protruding from the board 15, and a one-shaped stopper piece 17 is inserted into the hole drilled in the protruding piece 22.
Insert the bolt 19 whose lower end is fixed into the upper end of the protrusion 22.
The protrusion 22 is attached to the nut 16 screwed onto the bolt 19 on both sides of the
When the canopy 1 is opened as shown in FIG. 2 with a stopper piece 17 fixed to the stopper piece 17, when the second link fitting 12 rotates downward about the pivot portion 13, the second link fitting 12
The lower edge of the upper end of the stopper piece 17 fits into and engages with the U-shaped groove 17a at the lower end of the stopper piece 17, thereby restricting rotation of the second link fitting 12 beyond a predetermined angle.
この所定角度はナツト１６をゆるめてボルト１９を斜め
上下方向に移動させることによって適宜調節できるもの
であって、この調節はストッパ片１７の表面に刻印せる
目盛り２０を見ながら行なって、両側のストッパ片１７
の位置を等しくするわけである。This predetermined angle can be adjusted as appropriate by loosening the nut 16 and moving the bolt 19 diagonally up and down. Piece 17
This means that the positions of are made equal.
つまり、リンク金具１２の上縁と目盛り２０との交叉位
置が、回動角度によって異なるのを利用して交叉位置を
読み取ることによって両側のストッパ片１７の位置を等
しく調整できるわけである。In other words, the positions of the stopper pieces 17 on both sides can be adjusted equally by reading the intersection position using the fact that the intersection position between the upper edge of the link fitting 12 and the scale 20 differs depending on the rotation angle.
勿論性の基準点を設定してこの基準点と目盛り２０との
位置関係を読み取ることによっても等しく調整すること
は可能である。Of course, it is also possible to make equal adjustments by setting a reference point and reading the positional relationship between this reference point and the scale 20.
図中２１は下端が第１のリンク金具１１の下端部に固定
され、上端が開口部６の天井裏４開口縁に固定された引
張りばねである。In the figure, reference numeral 21 denotes a tension spring whose lower end is fixed to the lower end of the first link fitting 11 and whose upper end is fixed to the opening edge of the attic 4 of the opening 6.
本考案はストッパ金具を、開口部の内側面に固定した基
板と、基板に突設した突片に穿孔せる孔に移動自在に挿
着したボルトと、このボルトの下端に上端を固定し先端
を第２のリンク金具上端に係合するストッパ片とで構成
し、該ストッパ片表面に移動量を示すための目盛りを設
けであるので、ストッパ片の位置を目盛りを見ながら調
節でき、そのため位置の設定が容易に行なえ、また両側
のストッパ金具の位置を等しく設定することができてス
トッパ金具の位置不揃による天蓋の開閉トラブルがない
という利点を有する。The present invention consists of a base plate fixed to the inner surface of the opening, a bolt movably inserted into a hole drilled in a protrusion protruding from the base plate, and an upper end fixed to the lower end of the bolt, with the top end fixed to the lower end of the bolt. It consists of a stopper piece that engages with the upper end of the second link metal fitting, and a scale is provided on the surface of the stopper piece to indicate the amount of movement, so the position of the stopper piece can be adjusted while looking at the scale, and therefore the position can be adjusted. It has the advantage that the setting can be easily performed, and the positions of the stopper metal fittings on both sides can be set equally, and there is no trouble in opening and closing the canopy due to uneven positions of the stopper metal fittings.
