Description

The present invention relates to a member that closes a gap formed when a door that opens and closes via a joint such as a hinge is opened, and an open door device to which the closing member is attached.

As a door attached to the doorway, an open door that can be opened and closed via a joint such as a hinge is known.
The hinged door is attached to the vertical rail of the frame fitted to the doorway via a hinge, and one of the hinge pieces constituting the hinge is fixed to the vertical rail side and the other butterfly piece is fixed to the door side.
FIG. 4 shows a case where the open door (a) is attached to the vertical rail (c) via a hinge (b), (a) shows a case where the open door (a) is open, and (b) shows a case where the open door (a) is open. The cases where the hinged door (a) is closed are shown respectively.

In the hinge (b), the butterfly piece (d) and the butterfly piece (e) extend from the shaft (f) and are oscillatingly supported, one butterfly piece (d) is fixed to the vertical crosspiece (c), and the other. The butterfly piece (e) is attached to the side surface (g) of the open door (a). Therefore, the hinged door (a) can be attached to the vertical rail (c) via a hinge (b) and can be opened and closed.
By the way, as shown in the figure, when the hinged door (a) is opened, a gap (chi) is formed between the hinged door (a) and the vertical crosspiece (c). Therefore, a finger may be inserted into this gap (chi) and the open door (a) may be closed in that state, and the finger may be caught between the vertical rail (c) and the open door (a) and cause serious injury. do. In particular, children and toddlers may unknowingly pinch their fingers.

Conventionally, various techniques have been known to prevent injuries by pinching fingers in the gap (chi) of the hinged door (a). However, there are problems that the structure is complicated, that the door is not versatile, and that the appearance of the hinged door (a) is impaired when the closing member is attached.

As described above, there is known a technique for preventing fingers from being caught in the gap formed when the hinged door is opened. A hinged door device configured by attaching bellows to close this gap is also known.
However, in the open door device to which the bellows are attached, when the bellows are closed, the bellows protrudes to the outside and the appearance of the open door device is spoiled.
The problem to be solved by the present invention is this problem. When the hinged door is closed, it can be folded neatly without protruding to the outside, and the gap formed when the hinged door is opened is filled with fingers. Provided are a closing member and an open door device so as not to be pinched.

As the gap closing member according to the present invention, a bellows that can be expanded and contracted is used, one side end is fixed to the vertical rail of the frame body, and the other side end is opened and fixed to the door. When the hinged door is closed, the bellows is folded, and when the hinged door is opened, it extends and closes the gap formed between the vertical rail and the hinged door.
Here, the present invention is not limited to the method of attaching the bellows, and it is also possible to fasten with screws, adhesives, or double-sided tape.

The height of the bellows that can close the gap formed when the hinged door is opened may be the area from the lower end to the upper end of the hinged door, but generally within the range where the fingers may be caught. good.
A plurality of bellows pieces having a certain width are connected to each other, and when the hinged door is closed, each bellows piece overlaps the surface of the hinged door and is folded. That is, it is designed so that it does not protrude in a random state.

The gap closing member according to the present invention is composed of elastic bellows, one bellows piece of the bellows is fastened to the vertical rail side, and the bellows piece on the other side is fastened to the open door side.
Therefore, if the hinged door is swiveled and opened via a hinge, a gap is formed between the vertical rail and the side surface of the hinged door, and this gap can be closed. That is, the folded bellows extends at the same time as the opening door opens, and the formed gap is closed.

Then, if the hinged door is closed, the bellows are folded, but the plurality of bellows pieces are folded so as to overlap the surface of the hinged door, and are compactly organized without protruding to the outside.
Therefore, the appearance of the open door is not spoiled by the bellows, the expansion and contraction movement of the bellows accompanying the opening and closing operation of the open door is always constant, and the life of the bellows is maintained for a long time.

A bellows constituting the gap closing member according to the present invention. It is sectional drawing which shows the open door device which attached the bellows, (a) is the case where the open door is open, (b) is the case where the open door is closed. It is a perspective view which shows the open door device which attached the bellows, (a) is the case where the open door is open, (b) is the case where the open door is closed. It is sectional drawing which shows the open door device which does not have a gap closing member, (a) is the case where the open door is open, (b) is the case where the open door is closed.

FIG. 1 is an example showing a bellows 1 constituting a gap closing member of an open door, and the bellows 1 has a plurality of bellows pieces 2a, 2b ... Extending in the vertical direction. The bellows pieces 2b, 2c ... Have a constant width, and the bellows pieces 2a, 2b, 2c ... Are connected via the connecting portions 3, 3 ..., And the connecting portions 3, 3 ... It can be folded by bending through ..., And conversely can be extended through the connecting portions 3, 3 ...
That is, the bellows 1 is expandable and contractible, expands and contracts with the opening and closing operation of the opening door, and is folded.

FIG. 2 is a specific example showing an open door device to which the bellows 1 is attached. The hinged door 4 is attached to the vertical rail 6 of the frame body fitted to the doorway via the hinge 5, and can be opened and closed via the hinge 5. The hinge 5 has two hinge pieces that rotate around an axis, while the side hinge piece 7 is fixed to the inner surface of the vertical rail 6 and the other side hinge piece 8 is fixed to the side surface of the open door 4. There is. Therefore, the hinged door 4 can be opened and closed by turning around the axis of the hinge 5.

FIG. 2A shows a state in which the hinged door 4 is open, and the bellows 1 shown in FIG. 1 is attached to the gap 9 formed when the hinged door 4 is opened to close the gap 9. I'm out. Therefore, the fingers are not caught in the gap 9.
The bellows piece 2a on the tip side of the bellows 1 is anchored to the surface 10 of the vertical rail 6, and the bellows piece 2g on the other side is anchored to the surface 11 of the opening door 4.
The front end side bellows piece 2a and the other side bellows piece 2g are connected by other bellows pieces 2b, 2c ..., And the gap 9 is closed.

In this case, the bellows pieces 2b, 2c ... Provided between the bellows piece 2a and the bellows piece 2g are not fully extended and are slightly bent through the connecting portions 3, 3 ... ing.
The width dimension of the tip side bellows piece 2a is large, and it is fixed to the surface 10 of the vertical rail 6 and at least wider than the width of the other bellows pieces 2b, 2c ... Inward from the vertical rail surface 10. It is extending.

FIG. 2B shows a case where the hinged door 4 is closed. If the hinged door 4 is closed, the extended bellows 1 is folded. In this case, each bellows piece 2b, 2c ... Of the bellows 1 is correctly folded and housed in the space 12 formed between the bellows piece 2a at the tip and the open door surface 11, and is in a random state on the outside. It does not stick out.
Here, the tip side bellows piece 2a is fastened to the surface 10 of the vertical rail 6 via double-sided tape, and the other end side bellows piece 2g is also fastened to the surface 11 of the opening door 4 via double-sided tape. There is.

FIG. 3 shows a specific example showing an open door device in which a bellows 1 is attached to an open door 4.
FIG. 3A shows a state in which the open door 4 is open, and FIG. 3B shows a state in which the open door 4 is closed. When the hinged door 4 is opened, the bellows 1 is extended, and the gap 9 formed between the bellows 1 and the vertical rail 6 is closed so that the fingers are not pinched.
Then, if the opening door 4 is closed, the extended bellows 1 is correctly folded and does not protrude outward in a random state.
