DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door provided at an entrance in a bathroom or the like of a barrier-free design having an entrance formed with a wide opening width.

[0002]

2. Description of the Related Art In a bathroom or the like having a barrier-free design,
The doorway is formed wide in consideration of the user entering and exiting in a wheelchair and a mobile nursing hoist accompanied by a caregiver. A folding door provided in such a wide doorway is disclosed, for example, in Japanese Patent Application Laid-Open No. The one described in Japanese Patent Application Laid-Open Publication No. H10-260, 1993 is known. This folding door is composed of a frame and a pair of two folding doors provided to be openable and closable on the frame, and a sufficient effective opening is obtained by opening the two folding doors so as to be folded right and left. Like that.

[0003]

In such a conventional folding door, for example, the dead space associated with the opening and closing operation can be reduced as compared with a door or the like, and the effective opening width is increased as compared with a sliding door or the like. Have the advantage that you can.
However, in the case where the folding door is cut down so as to correspond to various entrances having different dimensions, it is necessary to cut down two folding door bodies, that is, a total of four door bodies in a pair of two folding door bodies. In addition, it takes time to adjust the dimensions of the doorway.

According to the present invention, the dead space can be reduced and the effective opening width can be increased.
It is another object of the present invention to provide a folding door that can easily perform dimensional correspondence to doorways having different widths.

[0005]

According to the present invention, there is provided a folding door comprising a frame, and a pair of two folding doors which are provided on the frame so as to be openable and closable and are closed at the right and left intermediate portions.
At least one of the pair of two-fold folding door bodies is characterized in that it has a sleeve frame rotatably provided on a door-side vertical frame on the abutting side thereof.

According to this configuration, the opening formed by the frame is opened and closed by the pair of double-folded doors, so that the effective opening width can be made larger than that of a sliding door and the like, and the door can be opened. The dead space for opening and closing can be reduced as compared with the above. In addition, since at least one door frame of the pair of two-fold folded door bodies is provided with a sleeve frame rotatably, by preparing sleeve frames having various widths, or by appropriately cutting the sleeve frames, Dimensions can be easily adjusted for openings having different widths. That is, it is possible to use the two-folded door body for general use and to correspond to openings having various widths.

[0007] In this case, the upper frame of the frame has a discontinuous portion in which the rails of the nursing care hoist are orthogonal to each other at the left and right intermediate portions, and the sleeve frame is not closed when the pair of double folding doors is closed. It is preferable to close the opening gap corresponding to the continuous portion.

According to this configuration, when the pair of two-folded doors is closed, the pair of two-folded doors closes the opening except for the opening gap corresponding to the discontinuous portion of the upper frame, and the sleeve frame is closed at the discontinuous portion. The corresponding opening gap will be closed. That is, the upper ends of the vertical stiles of the pair of double folding doors do not reach the discontinuous portion of the upper frame even in the closed state, and do not come off from the discontinuous portion. Although the sleeve frame faces the discontinuous portion, it is rotatably provided on the vertical frame of at least one of the two-folded doors, so that the sleeve frame does not come off from the discontinuous portion. On the other hand, when the pair of two-folded doors are opened, the pair of two-folded doors are respectively brought to the vertical frame side in a normal bending form, and the sleeve frame is moved accordingly. Since the sleeve frame has a width that closes the opening gap corresponding to the discontinuous portion,
Even in the open state, it does not overhang the open part. In order to minimize the overhang to the open portion, it is preferable to provide the sleeve frames in the vertical frames of the two-folded doors.

In this case, the upper frame is composed of an upper left frame element and an upper right frame element which are arranged on a straight line with a discontinuous portion, and between the ends of the upper left frame element and the upper right frame element, It is preferable that a connecting member that connects the upper left frame element and the upper right frame element in a linear posture across the discontinuous portion is detachably attached.

According to this configuration, if the upper left frame element and the upper right frame element are connected in a straight line posture by the connecting member at the time of product shipment or construction, handling of the upper frame is facilitated.
If this is removed after construction, the connecting member will not obstruct the movement of the hoist.

In these cases, it is preferable to further include an opening / closing interlocking mechanism that, when one of the pair of two folding door bodies is opened / closed, opens and closes the other.

According to this configuration, the opening / closing interlocking mechanism causes
Since a pair of two-folded door bodies are operated to open and close in conjunction with each other, by opening and closing one of the two-folded door bodies, the other two-folded door body can be simultaneously opened and closed. Therefore, it is possible to save the trouble of separately opening and closing the pair of two folding door bodies.

In this case, one door vertical frame of the pair of two-folded door bodies is provided with a kick-out member for kicking out the other two-folded door body in the bending direction at the start of the opening operation. Preferably, the vertical frame is provided with a member to be kicked out corresponding to the member to be kicked out.

According to this configuration, when one of the two folding door bodies is used as the driving side and the other two folding door bodies are opened in conjunction with the driving side, the ejection member is kicked out at the start of the opening operation. Since the member is kicked out in the bending direction, it is possible to prevent the other two folding door bodies from being locked.

Similarly, one of the pair of two-folded door bodies is provided with a kicking member for kicking the other two-folded door body in the bending direction at the end of the closing operation. It is preferable that the frame be provided with a member to be kicked corresponding to the kick member.

According to this configuration, when one of the two folding door bodies is used as the driving side and the other two folding door body is closed in conjunction with the driving side, the kicking member changes the kicked member at the end of the closing operation. Since it is kicked in the bending direction, it is possible to prevent the other two-folded door body from being inadequately closed.

In these cases, one of the vertical door frame and the sleeve frame is formed with an arc-shaped concave portion which slides on each other to guide rotation, and the other has an arc-shaped convex portion having a shape complementary to the arc-shaped concave portion. It is preferable that a portion is formed and a seal member is interposed between the arc concave portion and the arc convex portion.

According to this configuration, the sliding contact between the arc-shaped concave portion and the arc-shaped convex portion allows the vertical rotation of the door-end vertical frame and the sleeve frame to be smoothly performed between the door frame and the sleeve frame. Sealability can be improved. In particular, since the sliding contact area can be increased by the arc concave portion and the arc convex portion,
The sealing property can be improved structurally.

In these cases, the vertical frame of the door and the sleeve frame include:
Sliding engagement with the upper rail and lower rail of the frame body,
A pair of upper and lower sliders for guiding opening and closing of the vertical door frame and the sleeve frame are provided, and at least the upper slider of the vertical door frame and the upper slider of the sleeve frame are integrally connected. Is preferred.

According to this configuration, the opening and closing movement of the sleeve frame can be guided to the upper rail and the lower rail of the frame body via the pair of upper and lower sliders, and the posture of the sleeve frame can be stabilized. . In addition, since at least the upper slider of the vertical frame of the door and the upper slider of the sleeve frame are integrally connected, the number of parts can be reduced, and the upper slider of the sleeve frame is reduced. Even when the upper slider faces the discontinuous portion of the upper frame, it is possible to effectively prevent the upper slider from falling off from the discontinuous portion.

In this case, the vertical door frame has a vertical frame hinge pin coaxially with the pair of upper and lower sliders, and the sleeve frame has a sleeve frame hinge pin coaxially with the pair of upper and lower sliders. The door end vertical frame and the sleeve frame are rotatably supported by a hinge arm rotatably supported at one end by a vertical frame hinge pin and rotatably supported at the other end by a sleeve frame hinge pin. Preferably, they are linked.

According to this structure, the hinge is not provided across the butted ends of the vertical frame and the sleeve frame.
Both can be connected rotatably. For this reason, the sealing structure between the vertical frame and the sleeve frame can be simplified.

Similarly, the vertical door frame has a vertical frame hinge pin coaxially with a pair of upper and lower sliders, and the vertical frame and the sleeve frame are rotatable at one end to the vertical frame hinge pin. It is preferable to be rotatably connected by a hinge arm which is rotatably supported at the other end and fixed to the sleeve frame.

According to this configuration, since the center of rotation is one point, the mutual rotation between the vertical frame and the sleeve frame is smooth.

In this case, it is preferable that the hinge arm is formed with a sliding contact guide that slides on the outer peripheral surface of the vertical door frame and guides the rotation of the vertical door frame.

According to this configuration, the sliding contact guide formed on the hinge arm makes it possible to further smoothly rotate the vertical frame and the sleeve frame relative to each other.

In these cases, the hinge arm includes a vertical frame side arm, a sleeve frame side arm, and a connecting arm that connects the vertical frame side arm and the sleeve frame side arm, and is substantially “U” in plan view. It is preferable that the connecting arm portion is formed in a character shape and is arranged so as to be exposed on the mountain fold side of the vertical frame of the door and the sleeve frame.

According to this configuration, since the connecting arm portion of the hinge arm formed in a substantially "U" shape in plan view is disposed so as to be exposed to the mountain fold side of the vertical frame and the sleeve frame, The vertical frame side arm portion and the sleeve frame side arm portion penetrate the doorside vertical frame and the sleeve frame to the mountain fold side, respectively. For this reason, by providing the sealing member on the valley fold side, reliable sealing is possible and the sealing structure can be simplified.
