Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bathroom or shower room having a barrier-free design with a wide entrance.
The present invention relates to folding doors and fittings provided at the entrance.

[0002]

2. Description of the Related Art In a bathroom or the like having a barrier-free design,
The entrance is widely formed in consideration of, for example, entering and exiting a disabled person in a wheelchair, and a folding door provided at such a wide entrance is disclosed, for example, in Japanese Patent Application Laid-Open No. 10-108888. This Orito has a frame and
A pair of two-fold folding doors provided on the frame so as to be openable and closable, and a sufficient effective opening width is obtained by opening the pair of two-fold folding doors so as to be folded right and left. . In this case, the pair of left and right two-fold folding doors have the same structure formed in the same width (the same width in the finding direction).

[0003]

In such a conventional folding door, the doorway can be opened widely when used by a disabled person or the like, but is useful when used by a healthy person.
It is necessary to open and close the folding doors individually, which complicates opening and closing operations. However, when a healthy person uses it, it is conceivable to open and close only one of the two folding doors, but in such a case, the opening width becomes narrow,
There is a problem that it is difficult to get in and out.

[0004] It is an object of the present invention to provide a folding door and a fitting that can easily and freely open an entrance as required without causing any obstacles in and out.

[0005]

SUMMARY OF THE INVENTION A folding door according to the present invention comprises a frame, a folding door main body mounted on the frame so as to be openable and closable, and a parent-child door relationship with the folding door main body. The folding door body is opened by being folded into the indoor side with one of the left and right vertical frame side ends of the frame body as a base end, and the child door body is opened on the other of the left and right vertical frame sides of the frame body. It is characterized by being opened by turning to the indoor side with the end as a base end.

According to this configuration, the opening portion surrounded by the frame is opened and closed by the folding door main body and the child door body which are in a parent-child door relationship. Therefore, only the folding door main body is opened.
A normal person is allowed to enter and exit normally, and by opening the folding door main body and the child door body, the opening can be widely opened, and entry and exit by a wheelchair or the like is allowed. That is,
Depending on whether or not the child door is opened, the effective opening width for entering and exiting can be appropriately adjusted as needed. Also,
Since both the folding door body and the child door body are opened to the indoor side with the vertical frame side end as a base end, the effective opening width can be relatively wide as compared with a sliding door, etc. Part of the door body can be prevented from protruding outside the room.

In this case, the combined vertical frame of the folding door main body and the combined vertical frame of the child door body are located at the butted ends of each other.
It is preferable that one is formed to have a convex cross-sectional shape and the other is formed to have a concave cross-sectional shape that is complementary to this.

[0008] According to this configuration, the mating portion of the folding door main body and the child door body has a structure that engages in an uneven shape.
In consideration of the respective opening and closing modes, the folding door main body can be opened and closed with the child door body closed, but the child door body cannot be opened and closed unless the folding door main body is in an open state. For this reason, even if a special locking mechanism is not used, it is possible to prevent the child door from being accidentally opened when the folding door main body is closed. In addition, the area for sealing can be increased due to the uneven shape of the mating portion.

In these cases, the assembling vertical frame of the child door body incorporates a locking mechanism for locking the closed state to the frame, and the locking mechanism is mounted on a guide rail formed on the frame. It is preferable that the latch mechanism be configured so as to be engaged and disengageable.

[0010] According to this configuration, the child door can be easily and quickly moved by engaging and disengaging the latch mechanism without requiring a locking operation and an unlocking operation such as a locking mechanism for dropping France. Can be opened and closed. In the case of a folding door with a barrier-free design having no step with the floor, it is preferable to provide the latch mechanism only at the upper end of the vertical stile.

In these cases, a hinge member having one end fixed to the frame side is incorporated in the child door door vertical frame of the child door body, and the child door door vertical frame is operated by an outdoor operation. It is preferable that a hinge detaching mechanism for releasing the fixing of the hinge member to the frame is incorporated.

In a general bathroom folding door, a hinge releasing mechanism for releasing the locked folding door from the outdoor side (undressing room side) is incorporated. According to the above configuration, the hinge releasing mechanism is provided from the outdoor side. By operating, the child door body, not the folding door main body, can be detached from the frame. The child door body is not heavy like the folding door body and is not folded in a free state, so that it is easy to handle and can be easily detached. In addition, an opening having a width necessary for rescue can be easily opened.

[0013] In these cases, it is preferable that an open / close handle is attached to at least the outdoor side of the folding vertical frame of the folding door body, and the open / close handle extends obliquely along the child door body. .

According to this configuration, the rotation stop of the slider in the folding door main body and the power point of the opening / closing handle can be sufficiently separated from each other, and the initial opening operation of the folding door main body is performed with a relatively small force by leverage. be able to. Moreover,
Since the opening / closing handle extends obliquely along the child door body, it is possible to effectively prevent the opening / closing handle from interfering with the folding door main body when the folding door main body is completely opened.

[0015] In these cases, it is preferable that the lower frame of the frame is disposed almost without a step on the floor surface on the indoor side and the floor surface on the outdoor side.

According to this configuration, as a folding door of a barrier-free design, a structure can be provided in which the effective opening width can be widened if necessary.

A fitting according to the present invention comprises a frame, a door body openably and closably mounted on the frame, and a child door body openably and closably mounted on the frame and having a parent-child door relationship with the door body. A lock for locking the child door to the frame is provided on one of the upper and lower vertical stiles of the child door with the door body, and a child door is provided on the other side. A latch mechanism for engaging and disengaging the frame is provided, and an operation knob of the lock is provided on a waist-high position on a finding surface of the vertical frame on the joining side.

In a barrier-free bathroom or the like, it is preferable to provide a folding door or door with a child door in order to increase the effective opening width. However, when not using this child door, it is necessary to lock it to the frame. However, if the lock mechanism is provided so as to be concealed on the end face of the vertical frame, an unnatural posture is imposed on the lock / unlock operation when sitting in a wheelchair or the like, resulting in poor operability. In addition, if the lock mechanism is provided at the upper and lower ends of the vertical frame for secure locking, two lock / unlock operations must be performed, which is troublesome. On the other hand, in the fittings of the present invention, a lock for locking the child door to the frame is formed on one of the upper and lower vertical frames on the side of the child door, which is the upper side of the frame. Thus, only one lock / unlock operation is required, and the child door body can be securely fixed at the closed position. In addition, since a latch mechanism for engaging and disengaging the child door with the frame is formed on the other side, it is not necessary to support the child door so that the child door does not open when operating the lock.
Therefore, the operation of the lock can be performed with one hand. Further, since the operation knob of the lock is located on the waist-high position on the finding surface of the vertical frame on the mating side, the operation knob can be easily operated in a natural posture even when sitting in a wheelchair or the like. Note that the “hip height position” refers to a position at a height of 700 to 1000 (mm) from the floor.

On the other hand, the inner handle 13 is attached to a finding surface on the bathroom A side of the vertical door frame 43, and the outer handle 14
Is attached to a finding surface on the undressing room B side of the doorside vertical frame 43. As shown in FIGS. 5 and 6, the inner and outer handles 13, 14 have a pair of upper and lower arms 81, 81 whose base ends are screwed to a finding surface of the vertical frame 43, and both arms 81, 81. 81, and a grip portion 82 extending to the distal end portion. The arm 81 of the inner handle 13 extends from the vertical door frame 43 toward the oblique door bottom side along the door side door body 10, while the arm 81 of the outer handle 14
The sub door 4 extends from the vertical frame 43 toward the diagonal door, that is, toward the door end of the sub door 4.

The grip portion 82 has both ends at both arm portions 8.
The rod-shaped shaft portion 83 is fixed to each of the distal end portions of the rod-shaped shaft members 1 and 81 and is provided so as to connect the distal end portions to each other. The grip body 84 is rotatably supported by the rod-shaped shaft portion 83. I have. By the way, as in the embodiment, when the folding door main body 3 is opened and closed by the inner and outer handles 13 and 14 provided on the door tip side, the handle 13,
The direction of the force applied to the shaft 14 slightly changes, and the angles of the handles 13 and 14 themselves change. In response to this change,
By freely rotating the grip body 84, the user does not need to re-grip the grip body 84, and the folding door body 3 can be opened and closed smoothly.

Both inner and outer handles 1 constructed as described above
3 and 14 are hinge pins P of the upper and lower sliders 55a and 55b incorporated in the vertical door frame 43, ie, the door side door 1

In 3 you can pull it out and pull the outer handle 1
4, by pulling it forward, the door-side door body 10 is twisted around the hinge pin P, and the folding operation is started.

That is, the lever action on the long inner and outer handles 13 and 14 of the arm portion 81 and the mounting position of the inner and outer handles 13 and 14 on the hinge pin P
The force applied for opening is efficiently applied to the unlocking of the folding door latch mechanism 50. In addition, in both the inner and outer handles 13 and 14, the initial opening operation of the folding door main body 3 is a pulling operation that is most ergonomically operated, thereby preventing an erroneous operation and facilitating the operation. Furthermore, since the inner and outer handles 13 and 14 extend along the folding door main body 3 and the child door body 4, the handles 13 and 14 largely protrude in the expected direction with the folding door main body 3 and the child door body 4 closed. And there is no large protrusion in the opening in the open state.

Next, referring to FIG. 7 and FIG.
