BACKGROUND OF THE INVENTION
The present invention relates to a folding door provided at an entrance / exit in a water field such as a bathroom and a shower room having a barrier-free design having a wide entrance / exit.
[0002]
[Prior art]
In a bathroom and the like of a barrier-free design, the entrance / exit is widely formed in consideration of entrance / exit of a disabled person in a wheelchair. As a folding door provided at such a wide entrance / exit, for example, JP-A-10-108888 The ones described are known. This folding door is composed of a frame body and a pair of two-folding door bodies provided in the frame body so as to be freely opened and closed, and is sufficiently effective by opening the pair of two-folding door bodies so as to be folded left and right respectively. The opening width is obtained. In this case, the pair of left and right folding doors having the same structure formed in the same width (the same width in the direction of finding) is used.
[0003]
[Problems to be solved by the invention]
In such a conventional folding door, it is useful that the doorway can be widely opened when used by people with disabilities, etc., but when a healthy person uses it, it is necessary to open and close a pair of two folding door bodies respectively, A complicated opening / closing operation is forced. Of course, when a healthy person uses, it is conceivable to open and close only one of the two-folded doors. However, in such a case, there is a problem that the opening width becomes narrow and the entrance and exit cannot be performed satisfactorily.
[0004]
An object of this invention is to provide the folding door which can open | release a doorway freely as needed, without producing intrusion.
[0005]
[Means for Solving the Problems]
  The folding door of the present invention includes a frame, a main two-fold folding door that opens and closes while being guided by the frame, and a secondary 2 that is guided by the frame and opens and closes and is narrower than the main two-folding door. A single folding door body, and a connecting mechanism for connecting the main two folding door body and the sub two folding door body to each other in a freely rotatable manner, with the main two folding door body and the sub two folding door body being connected, It is configured to be openable and closable between an open state in which each is folded and a closed state in which each line is unfolded. Left and right pivoting mechanisms that pivotably connect the frame, the vertical frame on the coupling side of the connecting frame and the main two-fold folding door body, and the vertical rod on the coupling side of the coupling frame and the secondary two-fold folding door frame. And each rotation mechanism has a hinge pin provided on each vertical shaft, and one end is pivotally supported by the hinge pin and the other end isConnecting frameAnd an arm member fixed to the head.
[0006]
  According to this configuration, since the main two-fold folding door body and the sub-two-fold folding door body are connected to each other by the connecting mechanism so as to freely rotate, the main and sub two-fold folding door bodies are respectively folded to be in an open state. Thus, the doorway can be opened widely. In addition, since the main two-fold folding door body and the sub-two-fold folding door body have different so-called widths, the entrance and exit is relatively narrow by folding only the main two-fold folding door body or only the secondary two-fold folding door body. Selective opening for different types of opening widths can be made. For example, when a disabled person in a wheelchair enters and exits, it is useful to open the main and sub two folding doors so that the entrance can be opened widely. When a healthy person enters and exits, only the main two folding doors are used. Opening does not complicate the opening / closing operation and does not hinder access. Further, by using two main folding doors, the dead space associated with opening and closing of the two folding doors can be reduced even if the effective opening width is wide. In particular, since the individual dead spaces generated by the two main folding doors overlap each other, the dead space can also be reduced in this respect.
  Further, when the main two-fold folding door body and the sub two-fold folding door body are folded, interference between the door bodies, in particular, collision with a projection such as a handle can be effectively prevented. Furthermore, the seal structure of the rotating part can be made simple and satisfactory.
  In addition, it is preferable that the effective opening width by the main two-fold door body is a dimension considering the case where a healthy person goes in and out or the caregiver pushes the wheelchair on which the handicapped rides, and the main and sub two-fold door body. The effective opening width according to is preferably a dimension considering the case where the disabled person goes in and out of the wheelchair.
[0007]
  Other folding doors of the present invention include a frame, a main two-fold folding door that is guided by the frame and disposed on the door tip side, and a main two-fold folding door that is guided by the frame to open and close. A secondary two-fold folding door formed narrower than the body and disposed on the door butt side, and a coupling mechanism for rotatably connecting the main two-fold folding door and the secondary two-fold folding door to each other. The single folding door body and the sub two folding door body are connected to each other, and are configured to be openable and closable between an open state where the folding door body is folded and a closed state where each of the folding door bodies is unfolded on a straight line. A connecting frame body that faces the gap with the sub-two-folded door body and closes the gap, a vertical rod on the connecting side of the connecting frame body and the main two-folded door body, and a connecting side of the connecting frame body and the sub-two-folded door body rod Left and right pivot mechanisms that pivotably connect the vertical shafts, and each pivot mechanism has a hinge pin provided on each vertical shaft and one end portion thereof. The other end portion is rotatably supported on the adipicConnecting frameAnd an arm member fixed to the head.
[0008]
  According to this configuration, since the main two-fold folding door body and the sub-two-fold folding door body are connected to each other by the connecting mechanism so as to freely rotate, the main and sub two-fold folding door bodies are respectively folded to be in an open state. Thus, the doorway can be opened widely. In addition, since the main two-fold folding door body and the sub-two-fold folding door body have different so-called widths, the entrance and exit is relatively narrow by folding only the main two-fold folding door body or only the secondary two-fold folding door body. Selective opening for different types of opening widths can be made. For example, when a disabled person in a wheelchair enters and exits, it is useful to open the main and sub two folding doors so that the entrance can be opened widely. When a healthy person enters and exits, only the main two folding doors are used. Opening does not complicate the opening / closing operation and does not hinder access. Further, by using two main folding doors, the dead space associated with opening and closing of the two folding doors can be reduced even if the effective opening width is wide. In particular, since the individual dead spaces generated by the two main folding doors overlap each other, the dead space can also be reduced in this respect.
  Further, when the main two-fold folding door body and the sub two-fold folding door body are folded, interference between the door bodies, in particular, collision with a projection such as a handle can be effectively prevented. Furthermore, the seal structure of the rotating part can be made simple and satisfactory.
  In addition, it is preferable that the effective opening width by the main two-fold door body is a dimension considering the case where a healthy person goes in and out or the caregiver pushes the wheelchair on which the handicapped rides, and the main and sub two-fold door body. The effective opening width according to is preferably a dimension considering the case where the disabled person goes in and out of the wheelchair.
[0009]
  In this case, it is preferable that a lock mechanism that locks the closed posture of the main double-folded door body and the secondary double-folded door body in the frame body is incorporated in at least the secondary double-folded door body.
[0010]
  According to this configuration, it is possible to perform a normal locking operation in consideration of privacy. For example, if the auxiliary two-fold folding door body is closed and locked, for example, when the main two-fold folding door body is to be opened and closed, the opening / closing operation can be performed. Accordingly, it is possible to effectively prevent the auxiliary two-fold folding door from opening and closing together.
[0011]
  Other folding doors of the present invention include a frame, a main two-fold folding door that is guided by the frame and disposed on the door tip side, and a main two-fold folding door that is guided by the frame to open and close. A secondary two-fold folding door formed narrower than the body and disposed on the door butt side, and a coupling mechanism for rotatably connecting the main two-fold folding door and the secondary two-fold folding door to each other. The single folding door body and the sub two folding door body are connected to each other, and are configured to be openable and closable between an open state where the folding door body is folded and a closed state where each of the folding door bodies is unfolded on a straight line. A connecting frame body that faces the gap with the sub-two-folded door body and closes the gap, a vertical rod on the connecting side of the connecting frame body and the main two-folded door body, and a connecting side of the connecting frame body and the sub-two-folded door body rod Left and right pivot mechanisms that pivotably connect the vertical shafts, and each pivot mechanism has a hinge pin provided on each vertical shaft and one end portion thereof. The other end portion is rotatably supported on the adipicConnecting frameAnd an arm member fixed to the head.
[0012]
  According to this configuration,Since the main two-fold folding door body and the sub two-fold folding door body are connected to each other by a connecting mechanism, the main and sub two-fold folding door bodies are folded open to open the doorway widely. can do. In addition, since the main two-fold folding door body and the sub-two-fold folding door body have different so-called widths, the entrance and exit is relatively narrow by folding only the main two-fold folding door body or only the secondary two-fold folding door body. Selective opening for different types of opening widths can be made. For example, when a disabled person in a wheelchair enters and exits, it is useful to open the main and sub two folding doors so that the entrance can be opened widely. When a healthy person enters and exits, only the main two folding doors are used. Opening does not complicate the opening / closing operation and does not hinder access. Further, by using two main folding doors, the dead space associated with opening and closing of the two folding doors can be reduced even if the effective opening width is wide. In particular, since the individual dead spaces generated by the two main folding doors overlap each other, the dead space can also be reduced in this respect.
  Further, when the main two-fold folding door body and the sub two-fold folding door body are folded, interference between the door bodies, in particular, collision with a projection such as a handle can be effectively prevented. Furthermore, the seal structure of the rotating part can be made simple and satisfactory.
  In addition, it is preferable that the effective opening width by the main two-fold door body is a dimension considering the case where a healthy person goes in and out or the caregiver pushes the wheelchair on which the handicapped rides, and the main and sub two-fold door body. The effective opening width according to is preferably a dimension considering the case where the disabled person goes in and out of the wheelchair.
