Abstract: A door pull (10) has a fixing portion (11) fixed on a door stopper stile (8A) of a door, an operating portion (12) fixed slidably in the opening direction of the door and adapted to slide relative to the fixing portion (11) in the opening direction of the door, and a turning portion (13) supported by the fixing portion (11). A first end of the turning portion (13) is linked turnably with the operating portion (12),and turning in conjunction with sliding of the operating portion (12). A second end of the turning portion (13) projects towards a jamb. When the operating portion (12) slides, an abutment (132) at the second end of the turning portion (13) abuts against the jamb and biases the door in the direction away from the jamb, and the opening operation of the door is assisted.

Abstract: A door pull (10) including a fixing portion (11) fixed on the door stopper stile (8A) of a shoji, an operating portion (12) fixed slidably in the opening direction of the shoji relative to this fixing portion (11), and a turning portion (13) supported by the fixing portion (11), a first of which is linked turnably with the operating portion (12), turning in conjunction with a slide of the operating portion (12), and a second end projects towards the jamb. According to this door pull (10), by sliding the operating portion (12), an abutment (132) representing the second end of the turning portion (13) abuts against the jamb and biases the shoji in the direction away from the jamb, and the opening operation of the shoji is assisted. Therefore, the door pull (10) having an opening assistance mechanism is constituted by a simple structure of having only the fixing portion (11), the operating portion (12) and the turning portion (13) and the number of component parts can be reduced thereby.

Abstract: A partitioning sash comprises at least one multi window mullion for forming a multiple window portion, at least one salient corner mullion for forming a salient angle portion and at least one reentrant corner mullion for forming a reentrant angle portion. The multi window mullion, the salient corner mullion, and the reentrant corner mullion has the same dimension measured in a direction parallel to a width of the sash. Each of the salient corner mullion and the reentrant corner mullion is constituted of a mullion body and an auxiliary frame body. The mullion body has a glass receptacle groove on a side surface to be located at one side in a direction parallel to the width of the sash, end has recesses on side surfaces to be located at both sides in a direction parallel to the depth of the sash.
