次に、バランサー装置51について説明する。本実施形態において、図13及び図14では、左右の縦枠23,24のうち、縦枠24にバランサー装置51を配置した図のみ図示しており、縦枠23にバランサー装置51を配置した図は図示を省略している。縦枠23にバランサー装置51を配置した図については、図13及び図14の縦枠24にバランサー装置51を配置した図を左右対称とした図において、縦枠24の符号に代えて縦枠23に対応した符号を用いた図を援用できる。
Next, the balancer device 51 will be explained. In this embodiment, FIGS. 13 and 14 only show a diagram in which the balancer device 51 is arranged in the vertical frame 24 of the left and right vertical frames 23 and 24, and a diagram in which the balancer device 51 is arranged in the vertical frame 23. are omitted from illustration. Regarding the drawings in which the balancer device 51 is arranged in the vertical frame 23, in the drawings that are symmetrical with the drawings in which the balancer device 51 is arranged in the vertical frame 24 in FIGS. Figures with corresponding symbols can be used.
図11~図14に示すように、バランサー装置51は、外形が直方体形状に形成されるバランサー511と、ワイヤー512と、バランサーカバー52と、を備える。バランサー511は、ワイヤー512を巻き上げ方向に付勢する巻き上げばね(図示省略)と、ワイヤー512を巻き取るドラム(図示省略)と、を有するドラム式のバランサーである。
As shown in FIGS. 11 to 14, the balancer device 51 includes a balancer 511 having a rectangular parallelepiped outer shape, a wire 512, and a balancer cover 52. The balancer 511 is a drum-type balancer that includes a winding spring (not shown) that urges the wire 512 in the winding direction and a drum (not shown) that winds the wire 512.
バランサー511は、図13に示すように、左右の縦枠23、24内の上部において、縦枠23、24の上方側に形成されるバランサー配置部56内に配置されている。バランサーカバー52は、バランサー511を覆うように配置される。
As shown in FIG. 13, the balancer 511 is disposed in a balancer placement portion 56 formed above the left and right vertical frames 23, 24 at the upper portions of the vertical frames 23, 24. Balancer cover 52 is arranged to cover balancer 511.
ワイヤー512の一端部は、バランサー511の内部に取り付けられ、ワイヤー512の他端部は、下障子4の下框32の下部のワイヤー係止部47(図3参照)に係止されている。バランサー511は、ワイヤー512を介して下障子4に接続される。バランサー511は、ワイヤー512を巻き上げ方向に付勢する巻き上げばねにより、下障子4の荷重とのバランスを取って、任意の高さ位置で下障子4を静止させて保持する。
One end of the wire 512 is attached to the inside of the balancer 511, and the other end of the wire 512 is locked to a wire locking portion 47 (see FIG. 3) at the bottom of the lower stile 32 of the lower shoji 4. The balancer 511 is connected to the lower shoji 4 via a wire 512. The balancer 511 balances the load of the lower shoji 4 with a winding spring that urges the wire 512 in the winding direction, and holds the lower shoji 4 stationary at an arbitrary height position.
ここで、本実施形態のドラム式のバランサーとは異なるスパイラル式のバランサーがある。スパイラル式のバランサーは、ドラムを有さずにスパイラルバネを有しており、スパイラルバネにより障子を吊り下げるため、ドラム式のバランサーに比べて、耐荷重が小さく、外形も小さい。一方、ドラム式のバランサーは、重量が重い障子を吊り下げ可能なドラムを有しており、スパイラル式のバランサーに比べて、耐荷重が大きく、外形も大きい。本実施形態においては、バランサー511として、下障子4の荷重を考慮して、耐荷重が大きいドラム式のバランサーを採用している。
Here, there is a spiral type balancer different from the drum type balancer of this embodiment. A spiral balancer does not have a drum but has a spiral spring, and because the spiral spring suspends the shoji, it has a lower load capacity and a smaller external size than a drum-type balancer. On the other hand, a drum-type balancer has a drum on which a heavy shoji screen can be suspended, and has a higher load capacity and larger external size than a spiral-type balancer. In this embodiment, as the balancer 511, a drum-type balancer with a large load capacity is adopted in consideration of the load of the lower shoji 4.
本実施形態のバランサー511は、ドラム式のバランサーであるため、外形が大きい。そのため、縦枠23,24を加工しない状態では、縦枠23,24の金属縦枠231,241の上下方向に延びる金属縦枠内方延出部231a,241a及び樹脂縦枠232,242が邪魔となり、縦枠23,24の内部の上部に、バランサー511を配置するスペースを確保できない。
The balancer 511 of this embodiment is a drum-type balancer, and therefore has a large external size. Therefore, when the vertical frames 23, 24 are not processed, the vertically extending metal vertical frames 231a, 241a and the resin vertical frames 232, 242 of the vertical frames 23, 24 are in the way. Therefore, a space for arranging the balancer 511 cannot be secured in the upper part of the interior of the vertical frames 23 and 24.
これに対して、本実施形態においては、縦枠23,24において、金属縦枠231,241の上下方向に延びる金属縦枠内方延出部231a,241aの上端側の部分と、上下方向に延びる樹脂縦枠232,242の上端側の部分とを、バランサー511の上下方向の長さの分だけ切り欠くことで、縦枠23,24内の上部において、バランサー配置部56を形成した。
On the other hand, in the present embodiment, in the vertical frames 23, 24, the upper end portions of the metal vertical frame inwardly extending portions 231a, 241a extending in the vertical direction of the metal vertical frames 231, 241, and By cutting out the upper end portions of the extending resin vertical frames 232, 242 by the length of the balancer 511 in the vertical direction, a balancer placement portion 56 is formed in the upper part of the vertical frames 23, 24.
バランサー配置部56には、バランサー511が配置される。バランサー配置部56に配置されバランサー511には、バランサーカバー52(当て面別部材)が取り付けられる。バランサーカバー52は、縦枠23,24とは別部材で構成されており、縦枠23,24に取り付けられている。
A balancer 511 is arranged in the balancer arrangement section 56 . A balancer cover 52 (separate contact surface member) is attached to the balancer 511 disposed in the balancer placement portion 56. The balancer cover 52 is configured as a separate member from the vertical frames 23 and 24, and is attached to the vertical frames 23 and 24.
バランサー511は、外形が直方体形状に形成される。バランサー511は、上げ下げ窓1の見付方向の左右方向において所定の厚さを有すると共に上げ下げ窓1の見込方向において所定の幅を有し、上下方向に所定長さ延びる。バランサー511の左右方向の厚さは、左右方向において縦枠23,24の幅よりも小さい。バランサー511の見込方向の幅は、縦枠23,24の見込方向の全体の長さよりも短く、縦枠23,24の見込方向の長さの半分の長さよりも長い。
