Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to an inward-opening door.

[Prior art and its issues]

Since the inward-swinging door opens toward the indoor side, it may be difficult to open and close the door if the indoor space (entrance) is narrow.

For this reason, it is conceivable to form the part that accommodates the inward opening door so that it protrudes outward from the inner periphery of the opening in the building frame, but as proposed in Japanese Utility Model Application Publication No. 55-33385, this storage part is built into the building frame. If you store the door in this storage area by making it larger than the inner circumference of the opening,
It is inconvenient that the opening of the frame hits your hand or body when operating the knob or when entering or exiting.

Furthermore, if the storage area on the outdoor side is larger than the inner periphery of the frame opening, the door must inevitably open to the outside, and the hinge must be attached to the outdoor side of the door.

This idea was made to solve the problems mentioned above, and it was designed to create an inward-opening door that can be easily opened and closed even when the indoor space is small, does not cause any hindrance when entering and exiting, and has a good appearance. The purpose is to provide

[Means to solve the problem]

In the inward opening door according to this invention, the upper frame and the left and right vertical frames are constituted by a base portion disposed on the inner periphery of the opening in the building frame, and a storage portion protruding outward from the inner periphery of the frame opening.

The left and right vertical frame bases are each formed by a protruding piece that comes into contact with the base plate and the frame, and a mounting base piece is formed at the outdoor end of the base facing toward the opposite vertical frame side, and a plate is attached to the mounting base piece. A shaped storage section is extended toward the outdoor side.

Further, the storage portions of the upper frame, the left and right vertical frames, and the lower frame constitute a rectangular storage frame body, and the inward-opening door body is stored within this storage frame body.

This inward-opening door body is attached by a hinge attached to the base of the vertical frame on the indoor side.

〔Example〕

This invention will be explained in detail below based on an embodiment shown in the drawings.

FIG. 1 is a front view of an inward-swinging door according to this invention, in which an inward-swinging door body 4 is housed in an opening frame formed by a rectangular upper frame 1, left and right vertical frames 2, 2, and a lower frame 3. has been done.

The upper frame 1 and the left and right vertical frames 2, 2 are respectively constituted by base parts 1a, 2a arranged on the inner periphery of the opening of the building frame A, and storage parts 1b, 2b protruding from the inner periphery of the opening of the building frame towards the outdoor side. There is.

The base 1a of the upper frame 1 is formed into a substantially U-shaped cross section by the substrate 11 and the rising pieces 12, 12 that contact the frame A, and a mounting base is provided at the outdoor end of the base 1a toward the lower frame 3. A piece 13 is formed. A storage portion 1b having a substantially rectangular cross section is provided on the outdoor side of the mounting base piece 13.
is formed. A lip-shaped fitting groove 14 opening toward the indoor side is formed below the storage portion 1b, and the airtight material 5 is fitted into the fitting groove 14.

The bases 2a, 2a of the left and right vertical frames 2, 2 are each formed into a substantially U-shaped cross section by a base piece 21 and protruding pieces 22, 22 that abut on the frame body A, and the outdoor side ends of the bases 2a, 2a are A mounting base piece 23 is formed facing the opposite vertical frame 2 side. On the outdoor side of the mounting base piece 23, a plate-shaped storage portion 2b is extended toward the outdoor side. A fitting groove 24 in the form of a lip groove opening toward the indoor side is formed at the outdoor end of the storage portion 2b, and the airtight material 5 is fitted into the fitting groove 24.

The lower frame 3 is a member having a substantially U-shaped cross section, and the lower part thereof is buried in mortar. A stepped portion 31 having a reduced height is formed on the outdoor side of the lower frame 3 in order to improve watertightness.

The storage portion 1b of the upper frame 1, the storage portions 2b, 2b of the left and right vertical frames 2, 2, and the lower frame 3 as described above constitute a rectangular storage portion frame, and the expected width of the storage portion frame is The inward-opening door body 4 is housed inside. The inward-opening door body 4 is attached to the indoor side base 2a of one of the vertical frames 2 by a hinge 10 with one end attached.

The inward-opening door body 4 has upper and lower horizontal stiles 41, 41, left and right vertical stiles 42, 42 assembled into a rectangular shape, and decorative boards 43, 43 are pasted on both indoor and outdoor surfaces. Rectangular holes 61 are bored at appropriate positions in the decorative plates 43, 43, and glass plates 62 are fitted into them to provide a plurality of small windows 6. On the indoor side of the expected width of the upper stile 41 and the left and right stile 42, 42, there is a building frame A.
Projections 44 are formed toward the upper frame 1, left and right vertical frames 2, 2 when the inward opening door body 4 is closed.
The airtight material 5 can be contacted.

An airtight material 7 is attached to the lower stile 41 of the inward-opening door body 4 via an attachment 71.
The tip of the tongue piece can come into contact with the upper surface of the lower frame 3.

Exterior finishing B, which is performed using mortar 8 or the like, is carried out so as to surround the main body of the storage unit that protrudes from the inner periphery of the building frame A toward the outside.

[Effect of idea]

This invention has the above configuration and can obtain the following effects.

○B The body of the inward-opening door is housed in the storage frame that protrudes from the periphery of the building frame to the outside, so even if the indoor space is small, the space for opening and closing the door body is located on the outside, making it easier to open and close. It becomes possible to do so.

○B A mounting base piece is formed at the outdoor end of the base facing the opposite vertical frame side, and a storage part is formed on the outdoor side of this mounting base piece, so the inner periphery of the storage part and the inner periphery of the base are When the door is opened by the width of the mounting base piece, a space (length L in FIG. 2) is created.
Therefore, even if the door is pulled by the knob, the building frame will not be disturbed, and when entering and exiting, it is difficult for people to collide with each other, making it easy to enter and exit.

○C Since the inward-opening door body is attached to the hinge attached to the base of the vertical frame on the indoor side, the hinge is not visible from outside, resulting in a good appearance.
