Description

[Detailed Description of the Invention] The present invention relates to a swinging door that is attached to a door frame so that the door can be opened and closed.

In a conventional swinging door, for example, as shown in FIG. 10, one vertical frame d of a door c is attached to one vertical frame b of a door frame a via a hinge e, and the indoor and external walls g, In this structure, h is crimped to the indoor/outside vertical sealing members j and k attached to the other vertical frame i to maintain airtightness, and a lock l is attached across the other vertical frame i and the other vertical frame f.

The lock l is the lock m attached to the other vertical frame f.
and a lock holder n attached to the other vertical frame i, where the lock lever m rests on the lock holder n and is locked, and a non-locking position in which the position is vertically shifted relative to the lock holder n. It is arranged to move up and down perpendicular to the door opening/closing direction.

For this reason, the lock m protrudes toward the other vertical frame i so as to overlap the lock holder n, so that when the lock m is in the unlocked position and the door is opened or closed, the lock m is inserted into the other vertical frame i. It may interfere with the inward facing piece o for attaching the sealing material, which is integrally formed with the.

Therefore, in order to prevent the lock m from interfering with the inward facing piece o for attaching the sealing material, the other vertical frame f is spaced apart from the other vertical frame i, and the lock holder n is made to protrude long toward the other vertical frame f. The overlap between the lock lever m and the lock holder n is set to a predetermined length.

Therefore, the distance between the other vertical stile and the other vertical frame becomes larger, and if the size of the door frame a is the same, the size of the stile assembly of the door c becomes smaller, and the glass attachment opening p becomes smaller. This results in poor lighting and reduced visibility.

The present invention was developed in view of the above circumstances, and its purpose is to provide a swinging door that can reduce the mounting distance between the vertical frame of the door frame and the vertical frame of the door frame assembly, and allows the door frame assembly to extend out. That's true.
