TECHNICAL FIELD OF THE INVENTION
The present invention relates to a handle mounting structure in a folding door having a large handle mounted inside and outside of a folding door provided in a bathroom or the like, and a folding door provided with the same.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a folding door to which a large-sized handle of this kind is attached, for example, the one described in Japanese Patent Application Laid-Open No. H11-293971 is known. This folding door is a so-called two-fold folding door, and is composed of a frame body and a folding door main body provided on the frame body so as to be openable and closable, and is opened so as to be folded into a room. An inner handle is attached to the door end side of the folding door main body on the indoor side, and an outer handle is attached to the outdoor side, and the inner handle extends to the door ass side along the direction of finding the folding door main body, and The handle extends toward the door end along the direction in which the folding door body is found.
In this case, the center of rotation (sliding portion) of the door end side door body in the folding door body is located closer to the door end than the mounting position of the inner and outer handles, and the inner handle shifts from the pushing operation to the folding operation. Then, the folding door main body is opened, and with the outer handle, the transition from the pulling operation to the folding operation is performed, so that the folding door main body is opened.
[0003]
[Problems to be solved by the invention]
By the way, in the opening / closing operation of the folding door, especially in the initial opening operation, it is necessary to release the latch from the rail, so that a relatively large opening force is required and it is difficult to adjust the force. On the other hand, the above-mentioned conventional folding door solves the above-mentioned problem by using a large-sized handle and by positioning the rotation center of the door-side door body sufficiently close to the door bottom side.
However, in such a conventional configuration, the folded door body not only protrudes greatly to the outside of the room, but also needs to perform a pushing operation with the inner handle and a pulling operation with the outer handle in the initial opening operation. For this reason, there has been a problem that the push-pull operation is easily erroneous for the user, and the opening operation is extremely complicated.
[0004]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a handle mounting structure in a folding door that can perform an initial opening operation with both inner and outer handles by a pulling operation and a relatively small force, and a folding door provided with the same.
[0005]
[Means for Solving the Problems]
The handle mounting structure of the folding door according to the present invention is such that the inner handle facing the indoor side and the inner handle facing the outdoor side are located at the door end side end of the folding door main body which is attached to the frame body with the indoor side as the folding side. In the handle mounting structure of the folding door to which the outer handle is attached, the inner handle is attached to the door end side with the base end located closer to the door end than the center of rotation of the door top, and attached to the tip end. The handle has a grip portion and extends to the door end side, and the outer handle is attached to the door end side end with the base end located closer to the door end than the center of rotation of the door end, and at the tip end. It is characterized by having a grip portion and extending to the door end side.
[0006]
According to this configuration, the inner handle extends toward the door end, while the outer handle extends toward the door end. Both the inner and outer handles are attached to the door end side from the center of rotation of the door end side end. For this reason, by pulling both the inner and outer handles, the folding force can be directly applied to the folding door body with the rotation center as a fulcrum, and the initial opening operation can be performed smoothly. Also, with the inner handle, the folding door main body can be opened by shifting from the pulling operation to the folding operation, and similarly with the outer handle, the folding door main body can be opened by shifting from the pulling operation to the folding operation. Therefore, in the initial opening operation requiring the most opening force, both the inner and outer handles can be released by the pulling operation. In particular, the pulling operation is easier to apply a force than the pushing operation, and can be released by the same and natural pulling operation on the indoor side and the outdoor side. There is no hesitation in opening the main unit. In addition, since the inner handle extends to the side of the door and the outer handle extends to the side of the door, the folding door main body can be initially opened with a relatively small force by leverage.
[0007]
In this case, it is preferable that the inner and outer handles extend along the folding door body in the finding direction.
[0008]
According to this configuration, since the inner and outer handles are positioned so as to be substantially parallel to the folding door main body in the completely open state, it is possible to effectively prevent the inner and outer handles from interfering with the folding door main body. Further, since the inner and outer handles do not protrude greatly in the expected direction with respect to the folding door body in the completely closed state, the handles do not become an obstacle. In addition, it is preferable to provide a gap between the grip portion and the surface of the folding door main body at least so that a hand holding the grip portion does not touch the folding door main body.
[0009]
In these cases, each grip portion extends in the vertical direction, and the grip portion of the inner handle and the grip portion of the outer handle are disposed at 180 ° point symmetric positions with respect to the center of rotation on the door end side. Is preferred.
[0010]
According to this configuration, between the inner handle and the outer handle, the respective points of force (grip portion) and the point of action (center of rotation) are at the same distance. Can be opened with exactly the same opening force when the outer handle is opened and when the outer handle is gripped from the outdoor side.
[0011]
In these cases, it is preferable that each grip portion extends in the vertical direction and is configured to be freely rotatable around a vertical axis.
[0012]
According to this configuration, both the inner and outer handles open the folding door main body by shifting from the pulling operation to the folding operation, and close the folding door main body by the reverse operation, but in the transition from the pulling operation to the folding operation, Since the grip portion rotates freely, it is not necessary to re-grip the clip portion, and the opening force can be continuously and efficiently applied to the folding door body. Therefore, the operability of the inner and outer handles can be improved, and the folding door body can be smoothly opened and closed.
[0013]
A folding door according to the present invention is characterized in that the folding door according to any one of claims 1 to 4 is provided with a handle mounting structure.
[0014]
According to this configuration, the folding door main body can be smoothly opened and closed with a relatively small force and the same opening and closing operation indoors and outdoors.
[0015]
In this case, it is preferable to provide a child door body which is located on the door tip side of the folding door main body and is attached to the frame so as to be freely openable and closable with the folding door main body.
[0016]
According to this configuration, it is possible to obtain a normal effective opening width in which only the folding door body is opened, and a wide effective opening width in which the folding door body and the child door body are opened, and the opening width can be adjusted as necessary. it can.
[0017]
In this case, it is preferable that the clip portion of the outer handle is located within the width of the child door body in the finding direction.
[0018]
According to this configuration, the outer handle extending to the child door body side is accommodated within the width of the child door body, so that the grip provided at the distal end of the outer handle can effectively interfere with the side wall and the like on the outdoor side. Can be prevented.
[0019]

Similarly, the child door body 4 is also provided with a sealing piece so as to be continuous on its four circumferences. ing.
[0029]
Further, in the vertical door frame 43, a door upper slider 55a and a door lower slider 55b having hinge pins P integrally formed at both upper and lower ends thereof are rotatably incorporated. Similarly, the upper door bottom slider 56a and the lower door bottom slider 56b having hinge pins P integrally formed at both upper and lower ends thereof are rotatably incorporated in the vertical door bottom frame 46. The door top upper slider 55a and the door head lower slider 55b are slidably engaged with the upper guide rail 23 and the lower guide rail 29, respectively, and guide the opening and closing of the door side door body 10. Further, the upper door bottom slider 56a and the lower door bottom slider 56b are engaged with the upper guide rail 23 and the lower guide rail 29, respectively, and their positions are regulated in this state. Guide.
[0030]
That is, the upper door bottom slider 56a and the lower door bottom slider 56b are fixed to the upper and lower guide rails 23 and 29 in a state where the slide is restricted. Thus, the folding door main body 3 is in a state where the door end side door body 10 and the door bottom side door body 11 are linearly arranged side by side around the hinge pins P of the sliders 55a, 55b, 56a, 56b. The opening and closing operation is performed between a state where the door-side door body 10 is folded on the side of the bathroom A so that the door-side door body 10 is overlapped on the rear-side door body 11.
[0031]
The small door body 4 includes a small door upper frame 61 and a small door lower frame 62, each of which is made of an extruded profiled material of aluminum, a small door door vertical frame (child door combining vertical frame) 63, and a small door door bottom. The vertical frame 64 and the vertical frame 64 are assembled together, and a vertically long panel body 65 is fitted therein. Further, the small door lower frame 62 is formed with a ventilation gallery 66 following the door end side door body 10 and the door bottom side door body 11 (see FIG. 1).
[0032]
The small door door vertical frame 63 incorporates a child door latch mechanism 68 at an upper end thereof and an end cap 69 at a lower end thereof (all will be described later in detail). The small door upper vertical frame 64 incorporates a child door upper slider 70a and a child door lower slider 70b each having hinge pins P at upper and lower ends thereof, and the child door upper slider 70a has a child door body 4 attached thereto. Is detached from the frame body 2 and a hinge detachment mechanism 71 is integrally incorporated (details will be described later).
[0033]
The child door upper slider 70a and the child door lower slider 70b are engaged with the upper guide rail 23 and the lower guide rail 29, respectively, and are immovably fixed in this state. As a result, the child door body 4 is opened toward the bathroom A in the form of a hinged door centering on the hinge pins P of the upper and lower sliders 70a, 70b. Further, the closed state of the child door body 4 is regulated by the child door latch mechanism 68 locked to the upper guide rail 23. Although the operation is troublesome, a mechanism similar to the lock mechanism 50 of the folding door body 3 or a French dropper may be provided instead of the latch mechanism 68.
[0034]
Next, with reference to FIG. 5, the structure of the portion (butting portion) of the folding door main body 3 and the child door body 4 and the structure around the inner and outer handles 13 and 14 will be described. The folding door main body 3 and the child door body 4 are closed by abutting the door vertical frame 43 of the folding door main body 3 and the child door vertical frame 63 of the child door body 4. In this case, the abutting end 43a of the vertical door frame 43 is formed in a convex shape having a semicircular cross section, and the abutting end 63a of the vertical door frame 63 is substantially complementary thereto. It is formed in a concave shape having a typical cross-sectional shape. Further, a sealing piece 58 inside the door tip is located at the butt end 43a of the vertical door frame 43 on the bathroom A side, and a dressing room B side is located at the butt end 63a of the vertical door frame 63 at the door end. The outside door-side sealing pieces 73 are respectively attached, and the bathroom A and the undressing room B are double-sealed.
[0035]
In this case, the butted end 43a of the vertical door frame 43 formed in a convex shape engages with the butted end 63a of the vertical door frame 63 in the sub door formed in a concave shape, so that the closed end is closed. From the state, opening of only the folding door body 3 is permitted, but opening of only the child door body 4 is prevented. That is, the child door body 4 can be opened only when the folding door main body 3 is opened. This prevents opening of only the child door body 4 from the closed state.
[0036]
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 dressing room B side of the vertical door 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 the 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 portion 81 of the inner handle 13 extends from the vertical door frame 43 toward the oblique door bottom along the door-side door body 10, while the arm portion 81 of the outer handle 14 has a vertical door frame. It extends from 43 toward the diagonal door end side along the child door body 4, that is, toward the door bottom side of the child door body 4.
[0037]
The grip 82 has both ends fixed to the ends of the arms 81, 81, respectively, and a rod-shaped shaft 83 provided to connect the ends, and a rotatable shaft to the rod-shaped shaft 83. The grip body 84 is supported. By the way, in the case where 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 as in the embodiment, the direction of the force applied to the handles 13 and 14 changes delicately in the opening and closing operation process. The angles of the handles 13, 14 themselves change. In response to this change, since the grip body 84 freely rotates, the user does not need to re-grip the grip body 84, and the folding door body 3 can be opened and closed smoothly.
[0038]
The inner and outer handles 13, 14 configured as described above are shifted closer to the door butt side than the hinge pin P of the upper and lower sliders 55 a, 55 b incorporated in the vertical door frame 43, that is, the rotation center of the door side door body 10. In the position, it is attached so as to face each other across the vertical frame 43 of the door. Further, the center distance between the grip portion 82 serving as the point of force and the hinge pin P serving as the point of action is configured so that the inner handle 13 and the outer handle 14 have the same distance. For this reason, the length of the arm portion 81 of the outer handle 14 is slightly longer than that of the inner handle 13.
[0039]
Therefore, in the opening / closing operation of the folding door body 3, particularly in the initial opening operation of the folding door body 3, the opening operation from the bathroom A side and the opening operation from the undressing room B side are both performed with exactly the same force. be able to. Also. In the initial opening operation of the folding door body 3, the inner handle 13 is pulled forward, and the outer handle 14 is also pulled forward, so that the door-side door body 10 can be twisted about the hinge pin P. Then, the folding operation is started.
[0040]
That is, by the lever action of 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 with respect to the hinge pin P, the force applied for opening is efficiently locked by the folding door latch mechanism 50. It is made to act on release. In addition, in both the inner and outer handles 13, 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 both the inner and outer handles 13 and 14 extend along the folding door body 3 and the child door body 4, the handles 13 and 14 largely project in the expected direction in a state where the folding door body 3 and the child door body 4 are closed. And there is no large protrusion in the opening portion in the open state.
[0041]
Next, with reference to FIGS. 7 and 8, the end cap 69 and the child door latch mechanism 68 incorporated in the child door vertical frame 63 of the child door body 4 will be described. As shown in FIG. 7, the end cap 69 includes a base plate portion 91 that is abutted against the lower end of the sub door door vertical frame 63, a fitting portion 92 that is inserted into the lower end of the sub door door vertical frame 63, A partial seal piece 93 protruding from the lower surface of the base plate portion 91 so as to extend longitudinally is provided. The base plate portion 91 has a planar shape similar to the cross-sectional shape of the sub door door vertical frame 63, and is screwed from below in a state where it abuts against the lower end of the sub door door vertical frame 63. I have. The partial seal piece 93 is provided so as to be continuous with the lower seal piece 52 provided on the child door lower frame 62 with its end overlapping.
[0042]
As shown in FIG. 8, the child door latch mechanism 68 includes a latch protrusion 95 that engages with and disengages from the upper guide rail 29, a latch holder 96 that holds the latch protrusion 95, and a spring that is housed in the latch holder 96 and urges the latch protrusion 95. (Not shown). The latch holder 96 is formed integrally with a base plate portion 97 abutting on the upper end of the vertical door frame 63 and a fitting case 98 fitted into the upper end of the vertical door frame 63. . And also in this case, the base plate part 97 has a planar shape similar to the cross-sectional shape of the child door door vertical frame 63, Screwed from.
[0043]
The latch protrusion 95 has an arc slope 95a and a straight slope 95b in the expected direction, and is formed in a mountain shape in cross section. The latch protrusion 95 is locked to the upper guide rail 29 via the straight slope 95b, and is engaged with the upper guide rail 29 via the arc slope 95a. To leave. That is, it has a structure that is easily locked and hard to be separated. With the child door latch mechanism 68 configured as described above, the child door body 4 is restricted in the closed position, and when it is opened, it can be opened only by pushing the child door body 4 toward the bathroom A side. Has become.
[0044]
Next, with reference to FIG. 9, a description will be given of the hinge detachment mechanism 71 incorporated in the child door vertical frame 64 of the child door body 4. The hinge detachment mechanism 71 is incorporated at the upper end of the child door vertical frame 64, and includes the above-mentioned child door slider 70a and the detachment operation lever 100. The child door upper slider 70a includes a slider main body 101 that engages with the upper guide rail 29, a door wheel 102 that is incorporated in the slider main body 101, an engaging disk portion 103 that communicates with the lower end of the slider main body 101, and a lower end of the slider main body 101. And a coil spring 104 wound around the hinge pin P to urge the slider body 101 upward, and a case 105 for housing these components.
[0045]
The case 105 is fitted into and fixed to the upper end of the child door vertical frame 64 from above, and the slider body 101 is urged against the case 105 by a coil spring 104 so as to be able to come and go. As described above, the slider main body 101 is not slidable by a stopper block or the like fixed to the upper frame 5 (not shown). Therefore, the child door upper slider 70a functions as a hinge for rotating the child door body 4 together with the child door lower slider 70b.
[0046]
On the other hand, the release operation lever 100 has a lever body 108 slidably attached to a vertically extending elongated hole 107 formed at the upper end of the child door vertical frame 64 on the undressing room B side, and protrudes inside the lever body 108. It is integrally formed with the detachment pin 109 provided. The distal end of the detachment pin 109 is engaged with the upper side of the engagement disk portion 103 through a vertically long opening 105a formed in the case 105 of the upper child door slider 70a. Therefore, when the release operation lever 100 is operated to be pushed down, the slider main body 101 moves downward against the coil spring 104, and the slider main body 101 is separated from the upper guide rail 29.
[0047]
In this state, when the child door body 4 is pushed into the bathroom A side, the child door body 4 comes off the frame 2 and separates from the bathroom A side. After the user operates the folding door lock mechanism 49 from the bathroom A side to lock the folding door main body 3, when an unexpected situation occurs and it becomes necessary to rescue the user in the bathroom A from the undressing room B side By operating the hinge detachment mechanism 71, the child door body 4 is removed, and rescue operation is performed from the opening of the child door body 4. Of course, a similar hinge release mechanism may be provided on the door bottom vertical frame 46 of the folding door main body 3 so that the folding door main body 3 can also be released. However, since the child door body 4 is small and lightweight and has no bent portion, the detachment is possible. , And movement after separation can be easily performed.
[0048]
As described above, according to the present embodiment, the large inner handle 13 and the outer handle 14 are provided so as to extend in the oblique finding directions that are opposite to each other, so that both are most easily applied with force. This can be initially opened by a pulling operation and with a small force. Therefore, the folding door body 3 can be smoothly and smoothly opened and closed. In addition, since the child door body 4 that has a parent-child door relationship with the folding door main body 3 is provided, the opening can be widely opened as necessary without hindering normal access. .
[0049]
In the present embodiment, the folding door of the present invention has been described as a folding door in a bathroom. However, it is needless to say that the present invention can be applied to various folding doors including a so-called water place such as a shower room. In addition, it goes without saying that the handle mounting structure of the present invention can be applied to a normal folding door having no child door body.
[0050]
【The invention's effect】
As described above, according to the handle mounting structure of the folding door of the present invention and the folding door provided with the same, both the inner and outer handles are mounted closer to the door end than the rotation center of the door end side end, and the inner handle is the door end. Since the outer handle extends to the side of the door at the side, in the initial opening operation, both the inner and outer handles can be opened by pulling operation and applying a folding force. Further, the folding door main body can be initially opened with a relatively small force by the action of the lever. Therefore, the folding door main body can be smoothly and smoothly opened, and the operability can be improved.
