A hinge is provided which includes a frame-side base member adapted to be attached to an open frame and a door-side base member adapted to be attached to a door The frame-side base member is connected to a first plate and the door-side base member is connected to a second plate which is hinge connected to the first plate for holding the door so as to be capable of rotating. The second plate is separable from the door-side base member The door-side base member is shaped to be symmetrical about the vertical center line of the door edge, and is imbedded in the edge of the door without any protrusions from the door Further, the door-side base member is provided with a slit which penetrates the member in the width direction of the door and into which the second plate can be inserted from both the front and back sides of the door There is also provided a lock apparatus to lock the second plate inserted into the slit

Adjustable door hinge

Each of the hinges is positioned at upper and lower positions of the hinge-side vertical member correspondingly, wherein each position is symmetrical relative to the horizontal plane which divides the hinge-side vertical member in halves. A latch hole of the latch receiver is provided at a position of the latch-side vertical member where the member is divided in halves. A latch is positioned higher than a door handle capable of reversing. Each hinge is attached through one touch operation in order for use in a double hinged door system.

Double hinged door system

The present invention is directed to a frame that is placed at an opening portion in a partition provided in houses and the like, and specifically an adjustable frame comprising a plurality of frame adjustable fasteners including: a fixing member including an external thread member having a cylindrical manner for being incorporated at a partition side of an opening portion in a partition provided in houses and the like, and a base member for rotatably supporting said external thread member; and an internal thread member for being rotatably engaged with said external thread member and for installed in a frame body. The adjustable frame allows the external thread member to be turned, thereby adjusting its length, capable of fixing to the opening portion of the partition. Further, if necessary, the adjustable frame may be comprised of a pair of frame members having the width where a first frame member and a second frame member overlap in part in a thickness direction of the partition (wall thickness). It is provided a surface member so arranged that the end face of said second frame member that overlaps the surface of said first frame member and the edge surface thereof are covered, and a clip engaging member for allowing said first frame member to be brought into contact with the back surface of said second frame member is also provided. In the above-mentioned arrangement, therefore, the adjustable frame can be adapted for the wall thickness of the opening portion. The adjustable frame can be realized in a manner that the spacing between the partition and the frame can be readily adjusted by turning the external thread member at the time of installation of the frame at the opening portion of the partition provided in houses and the like. and can be adapted for different levels of the wall thickness by a separated frame member in a wall thickness direction of the opening portion.
