[Technical field to which the invention belongs]
The present invention relates to a multiple door such as a bathroom door.
[0002]
[Prior art]
In recent years, when an elderly person or a disabled person such as a wheelchair user uses a bathroom, there are increasing cases in which a caregiver goes in and out of the bathroom while supporting the elderly person or enters and leaves the bathroom as a wheelchair. In such a case, it is necessary to widen the entrance / exit of the bathroom, so it is conceivable to use a three-sided sliding door or a one-sided sliding door.
[0003]
However, in apartment houses, etc., it is generally difficult to use a three-door house where the size of the doorway of the bathroom is limited and the frame and shoji are expensive. In addition, a single-sliding door is expensive as in the case of a three-story door, and it takes time to construct a sleeve wall portion. Therefore, when taking a large doorway in the bathroom, a folding paper door with three sheets may be used.
[0004]
This type of folding door has three shoji screens connected at the summoning section, and at the time of construction, the three shoji screens are connected in the frame at the same time.
On the other hand, when opening the folding door shoji, each shoji is folded and brought to one side of the doorway.
[0005]
[Problems to be solved by the invention]
However, in the case of a three-sheet folding door, the door is built in a frame with a shoji unit that connects the shojis to each other. In addition to being heavy and difficult to handle, there is a problem that it is difficult to construct because it is necessary to simultaneously insert the shoji doors into the rails of the frame.
In addition, when an elderly person or the like in the bathroom suddenly becomes unable to move, there is a case where the shoji is to be removed urgently from the dressing room side, and there is a request that the shoji of the folding door can be removed with a simple operation.
The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a multiple door in which other shojis can be connected and removed while some of the shojis are built in a frame.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 includes a frame and a shoji unit, and the shoji unit includes a first shoji on the door side, a second shoji on the hanging side, and a first shoji. A third shoji between the first shoji and the second shoji, a first connecting portion for pivotally coupling the first shoji and the third shoji, and a third shoji and the second shoji are pivotally connected. and a second connecting portion, the first connecting portion includes the engaged member fixed to the third shoji, and a movable shaft member in the vertical direction provided on the first sliding door, the shaft member to an upper end It has an engagement groove with the upper rail, engages with the upper rail at the position engaged with the engaged member, and the shaft member is engaged at the upper position by the operation of the operation knob provided on the first shoji. It is characterized in that it is engaged with the member so as to be rotatable and the engagement with the engaged member is released at the lower position so that the connection between the first shoji and the third shoji can be released.
[0007]
In the invention according to claim 1, when an elderly person who is taking a bath with the shoji unit closed is suddenly unable to move in the bathroom, etc., when he / she wants to remove one shoji from the shoji unit in an emergency, etc. By operating an operation knob provided on the first shoji, the shaft member is moved downward to disengage the third shoji from the engaged member, and the first shoji and the third shoji are connected. To release. Thereby, a 1st shoji can be removed from a shoji unit as needed, with the shoji unit closed. For example, when a person falls down in the bathroom washing area, if the shoji unit is opened in a normal state, the shoji unit may not be opened by hitting the person who has fallen down when trying to fold the second and third shoji. However, in the present invention, since the first shoji can be removed while the shoji unit is closed, there is no such inconvenience.
[0008]
On the other hand, when installing a shoji unit on the inner periphery of the frame, connect the two shojis, the second and third shoji, into the frame, and then engage the two shoji door wheels on the rail of the frame. Then, the first shoji is connected to the third shoji by the first connecting portion. The first connecting portion is connected by positioning the shaft member of the first shoji at a lower position and placing it below the engaged member fixed to the third shoji, and then moving the shaft member upward from the lower position. It moves to a position and engages with an engaged member. As described above, the connection of the first connecting portion can be easily performed by simply moving the shaft member upward, and the first shoji is mounted after the two shojis of the second shoji and the third shoji are installed. Since it can be retrofitted, the shoji unit can be divided and handled, and the handling weight can be reduced and construction is easy.
[0009]
The operation of connecting the first shoji to the third shoji may be performed with the shoji unit opened or may be performed in a folded state.
[0010]
In addition, since the first shoji is connected to the third shoji by engagement, the first shoji can be found in a different size or can be easily changed to one with a different design. Is expensive.
[0011]
[0012]
Since the shaft member also engages with the upper rail at a position engaged with the engaged member fixed to the third shoji, there is no need to separately provide an engaging member for guiding the movement of the first shoji. The number of points can be reduced and the configuration can be simplified.

This second opening operation can be easily performed simply by operating the lever 25 to release the engagement between the engagement portion 33 and the door-end side door wheel 34 and the rails 13 and 14. The 1st shoji 15 rotates centering on the 1st connection part 27, and protrudes the 1st shoji 15 to the bathroom side. Therefore, the entrance / exit opening becomes wider by the substantially width dimension of the first shoji than the opening dimension (FIG. 6 (b)) of the pulling opening by the first opening operation.
[0041]
On the other hand, when the first shoji 15 is turned to the bathroom side by the second opening operation, the entire shoji unit 5 is in a folding door state, and the width of one shoji is the extended width dimension.
[0042]
In the present embodiment, normally, the doorway can be opened and closed by the first opening operation (pulling operation), and the second opening operation is performed as necessary to fully open. This second opening operation (full opening operation) does not rotate the entire shoji unit 5 but only the first shoji 15 so that it is easy to operate.
[0043]
Further, only one lower rail 13 and one upper rail 14 are provided, and the upper rail 14 and the lower rail 13 corresponding to the number of shojis are not required as in a conventional sliding door. it can.
[0044]
When closing the shoji unit 5, the first shoji 15 is rotated and returned to the rails 13 and 14, and the lever 25 is operated to move the door end side engaging portion 33 to the upper rail 14. After engaging the door end side door wheel 34 with the lower rail 13, the handle 23 is pulled along the directions of the rails 13 and 14 to close the shoji unit 5.
[0045]
Next, removal of the first shoji 15 will be described. In the case where an elderly person taking a bath suddenly becomes unable to move in the bathroom with the shoji unit 5 closed, in case of urgently removing one shoji, the lock pin 92 is released and the above-mentioned first Similarly to the second operation, the lever 25 is turned to release the engagement between the door-end side engaging portion 33 and the upper rail 14 and to release the engagement between the door-end side door wheel 34 and the lower rail 13. Further, the operation knob 69 of the first shoji 15 is lowered, the shaft member 63 is moved downward, and the engagement with the engaged portion 61 of the third shoji 17 is released. Thereby, since connection with the 1st shoji 15 and the 3rd shoji 17 is cancelled | released, the 1st shoji can be removed by pushing down the upper end of the 1st shoji 15 to the bathroom side with the handle 23. FIG. That is, in this Embodiment, the 1st shoji 15 can be removed from the shoji unit 5 as needed, with the shoji unit 5 closed.
[0046]
On the other hand, for the construction of the multi-door 1, the shoji unit 5 may be built in the frame 3 with the three shoji 15, 17, 19 connected, but the shoji unit 5 may be built separately. In this case, the second shoji 19 and the third shoji 17 are fitted into the frame 3 while being connected by the second connecting portion 29, and the engaging portions 36 and 38 and the door pulley are fitted to the upper and lower rails 13 and 14. After engaging the unit 71, the first shoji 15 is connected to the third shoji 17 by the first connecting portion 27. The first connecting portion 27 is connected by placing the shaft member 63 of the first shoji 15 at the lower position and placing it under the engaged member 61 fixed to the third shoji 17, and then the shaft member 63. Is moved from the lower position to the upper position to engage the engaged member 61. At the same time, the lower end of the first shoji 15 is engaged with the door cart unit 71 such that the first shoji 15 is put on the door cart unit 71 from above. In this way, since the first shoji 15 can be retrofitted after the two shojis of the second shoji 19 and the third shoji 17 are installed, the shoji unit 5 can be divided and handled, and the load at the time of construction can be reduced. Dispersible, easy to handle and easy to install.
[0047]
The operation of connecting the first shoji 15 to the third shoji 17 may be performed with the shoji unit 5 opened or may be performed in a folded state.
[0048]
In addition, since the first shoji 15 can be easily retrofitted to the third shoji, use a different shape or design, for example, the first shoji 15 without a panel to reduce the overall width of the shoji unit 5. Or, the dimensions of the shoji unit 5 can be easily changed according to the specification or design change.
[0049]
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. For example, the number of shojis constituting the shoji unit 5 is not limited to three, and any number of shojis may be used as long as it is more than that.
[0050]
The door end side engaging part 33 with the upper rail 14 and the door end side car 34 engaged with the lower rail 13 are not limited to being simultaneously interlocked by the lever 25, but are operated separately to the rails 14 and 13, respectively. It may be something that engages and disengages.
