Description

本発明は、建具に関する。 The present invention relates to a joinery.

従来、室内側へ開く障子を有する建具として、障子の框を見付方向の外側で枠体に開閉可能に連結した建具が知られている。また、枠体と障子との間を連結する開閉アームの移動を規制し、角度の開度を規制することで、障子を開く角度を段階的に調節することが知られている。具体的には、枠体と障子を連結する開閉アームを、開度が小さいか、障子を開いていない間は屈曲しており、開くにしたがって延伸するように構成し、屈曲端の上側に開度規制の操作部を配置した建具が提案されている（例えば、特許文献１参照）。 2. Description of the Related Art Conventionally, as a fitting having a shoji that opens to the indoor side, a fitting that is connected to a frame body so as to be openable and closable outside the direction of finding the shoji of the shoji is known. In addition, it is known to adjust the opening angle of the shoji step by step by regulating the movement of the open / close arm that connects the frame and the shoji and regulating the opening of the angle. Specifically, the open / close arm that connects the frame and the shoji is bent while the opening is small or when the shoji is not opened, and is configured to extend as it opens, and opens above the bent end. A joinery has been proposed in which an operation unit for degree regulation is arranged (see, for example, Patent Document 1).

The protruding portion 41 protruding from the shoji 3 is located on the indoor side, and the shoji 3 and the frame 2 are connected via the arm body 40.

図５（ａ）及び図５（ｂ）に示すように、障子３を室内側に倒すと、障子３を枠体２に対して回動させる障子３の回動軸となるヒンジ部３３４の延びる方向に対して直交する見込方向室内側に、アーム本体４０が延出するように移動する。また、アーム本体４０の移動に伴って、突出部４１がアーム本体４０の長手方向に沿って第１溝４５内をスライド移動する。突出部４１が規制部４７に至ると、アーム本体４０が第１溝４５の終端の上側の半円部分に形成される規制部４７に係止されて停止する。この状態が第１開度θ１開いた状態である。第１開度θ１は、障子３を開く角度が、閉じた状態から２０度〜４０度の間、好ましくは３０度程度である。 As shown in FIGS. 5A and 5B, when the shoji 3 is tilted indoors, the hinge portion 334 serving as a pivot shaft of the shoji 3 that rotates the shoji 3 with respect to the frame 2 extends. The arm main body 40 moves so as to extend to the indoor side in the prospective direction orthogonal to the direction. Further, as the arm body 40 moves, the projecting portion 41 slides in the first groove 45 along the longitudinal direction of the arm body 40. When the protruding portion 41 reaches the restricting portion 47, the arm body 40 is locked by the restricting portion 47 formed on the upper semicircular portion at the upper end of the first groove 45 and stops. This state is a state where the first opening θ1 is opened. The first opening θ1 is such that the opening angle of the shoji 3 is between 20 degrees and 40 degrees, preferably about 30 degrees from the closed state.

アーム本体４０が室内側に移動する間、図５（ｂ）に示すように、第２溝４６の終端側及び操作部４３は、障子３の縦枠２１の見込方向室内側の端部を越えて室内側に突出する。操作部４３は、障子３を第１開度θ１に開いた状態で、障子３の見込方向室内側の端部を越えた位置にある。使用者が、障子３を開く角度をさらに大きく開くよう調節したいと思った場合、この状態で操作部４３を、下から上に持ち上げる操作を行う。すると、規制部４７に係止されていた突出部４１が、図５（ｃ）及び図５（ｄ）に示すように、アーム本体４０が上方に持ち上げられた操作により、第１溝４５の終端から第２溝４６の基端へ移動し、規制部４７による規制が解除される。突出部４１は、その後、第２溝４６を先端側へスライド移動する。このように、操作部４３を操作して、障子３を開く角度を調節する。 While the arm body 40 moves to the indoor side, as shown in FIG. 5B, the terminal end side of the second groove 46 and the operation portion 43 extend beyond the end of the vertical frame 21 of the shoji 3 in the expected direction indoor side. Projecting indoors. The operation unit 43 is in a position beyond the end of the shoji 3 on the indoor side in the expected direction with the shoji 3 opened to the first opening θ1. When the user wants to adjust the opening angle of the shoji 3 to be further widened, in this state, the operation unit 43 is lifted from the bottom to the top. Then, as shown in FIGS. 5C and 5D, the protruding portion 41 locked to the restricting portion 47 is moved to the end of the first groove 45 by the operation of lifting the arm body 40 upward. To the base end of the second groove 46, and the restriction by the restriction portion 47 is released. Thereafter, the protruding portion 41 slides along the second groove 46 toward the distal end side. Thus, the operating unit 43 is operated to adjust the opening angle of the shoji 3.

突出部４１は、第２溝４６の先端側で止まる。この状態が第２開度θ２開いた状態である。第２開度θ２は、第１開度θ１よりも大きく、４０度〜６０度の間、好ましくは５０度程度である The protrusion 41 stops at the tip end side of the second groove 46. This state is a state where the second opening θ2 is opened. The second opening θ2 is larger than the first opening θ1, and is between 40 degrees and 60 degrees, preferably about 50 degrees.

障子３を閉めたいと思った場合は、障子を室外側に押すことで突出部４１は第２溝４６及び第１溝を４５基端側へ移動する。突出部４１が下方から上方に向かう際には、規制部４７で係止することはないので、アーム本体４０はスムーズに復帰する。 When it is desired to close the shoji 3, the projecting portion 41 moves the second groove 46 and the first groove to the base end side 45 by pushing the shoji outward. When the projecting portion 41 goes from the lower side to the upper side, the arm main body 40 returns smoothly because it is not locked by the restricting portion 47.

本実施形態によれば、以下の効果が奏される。
本実施形態では、枠体２と、室内側に開閉するように枠体２の内周側に保持された障子３と、を有する内倒し窓１を、枠体２及び障子３を連結する開閉アーム４を含んで構成した。また、開閉アーム４を、枠体２に端部が回動可能に取り付けられ、障子３を枠体２に対して回動させる回動軸の延びる方向に対して直交する方向へ移動するアーム本体４０と、障子３から突出し、アーム本体４０に係合するともにアーム本体４０の移動に伴って移動可能な突出部４１と、アーム本体４０に設けられ、障子３を開く角度を調節するように操作する操作部４３と、を含んで構成した。また、アーム本体４０を、障子３が第１開度まで開くように突出部４１が内部をスライドする第１溝４５と、第１溝４５から連続して形成され、障子３が第１開度θ１よりも大きい第２開度θ２まで開くように突出部４１が内部をスライドする第２溝４６と、突出部４１の第１溝４５から第２溝４６への移動を規制する規制部４７と、を含んで構成した。また、操作部４３は、角度を調節するときに、障子３の見込方向室内側の端部を越えて室内側に突出し、操作により規制部４７による規制を解除するようにした。 According to this embodiment, the following effects are produced.
