Description

  The present invention relates to a folding door opening and closing device.

  Recently, those using folding doors for closets and furniture doors are frequently used. As shown in FIG. 31, the folding door has a pair of doors, and a rotating member 4 such as a hinge or a pivot hinge is attached to an intermediate connection portion of the door. A door 6 and a guide member with good slippage are mounted so as to be movable in the lateral direction. In addition, there are a type in which the rails 5 are arranged on both upper and lower sides and a type in which the rails 5 are arranged only in the upper part and are opened and closed in a state where the door is suspended, but the opening and closing operation itself is the same.

  As shown in FIG. 31, as a basic operation, as a result of the operation of pulling the vicinity of the position of the rotating member 4 of the pair of folding doors to the front, the two door bodies protrude toward the front and start to be bent into a V shape, and thereafter The door 6 is moved along the rail 5 by the operation of moving in the horizontal direction, and the V-shape is opened while being narrowed. At this time, if either one of both ends of the door body is held on the frame body 8 side so as to be rotatable only by the pin hinge 7 or the like, the opening / closing direction becomes one direction, and two door bodies are on the side held by the frame body 8. It can be fully opened in the folded state.

  As a feature of this folding door, the size of the front end of the door protruding to the front side when opened is smaller than that of a conventional hinged door. The problem of the door tip protruding at the time of opening is important. Recently, the average height of young people has increased, and the closet for storing long coats inevitably requires a certain height. If a high height is used, there is a problem that the upper position of the door is large and protrudes to the near side and collides with an umbrella portion of a fluorescent lamp suspended from the ceiling. The same can be said when the laundry is dried in the room. Further, in a relatively small room, it may be difficult to pass when the door is opened.

  Since the dotted folding doors have the same open dimensions in pairs of two, it can be said that only half of the sliding doors are required, which is very excellent. Here, if the width of one folding door is further reduced, the protruding dimension can be reduced, but naturally the open dimension obtained by a pair of two sheets becomes narrow. In addition, since it is a condition that the mechanism opens and closes in pairs, for example, when an opening dimension of an arbitrary constant width is required, a configuration in which a pair of two folding doors is attached to one set or two sets on the left and right Thus, a case in which a pair of folding doors is too small and two pairs are too large with respect to the required open dimensions is likely to occur.

  Next, considering the operability at the time of opening and closing, first, as shown in FIG. 31, it is necessary to first pull the Y position near the rotary member 4 of the door in the closed state. If it deviates to both ends, most of the force acts as a force for pulling the door wheel 6 and the frame body 8, and it is difficult to bend into a V shape. Moreover, if it continues pulling only to the near side, it will be stretched from a state where it is folded to some extent, and it is necessary to operate it to move laterally before this stage.

  Japanese Patent Application Laid-Open No. 2003-074221 has been devised in the shape of the gripping member so that this operation can be carried out effectively, and has a large size so that it is easy to apply a force in the lateral direction after pulling forward. It is formed in an oval pipe shape. That is, in the above folding door, a smooth opening operation cannot be obtained unless the first pulling operation and the lateral movement operation are continued in a timely manner. Therefore, the operability when opening the folding door is far inferior to the opening door that is simply opened in the door body having the same width.

  Further, in the closing operation, it is necessary to pull the vicinity of the X position in the lateral direction along the rail 5 in the state where the door is completely folded and the door is substantially perpendicular to the rail 5 as shown in FIG. . X position is relatively difficult to hold because it is at the back of the protruding folding door, and it is necessary to extend and operate from the front, and the Y position that is folded and protrudes to the front side If pushed in the direction, the door wheel 6 does not slide laterally along the rail 5, and it may be folded back while being folded, which may cause damage. Therefore, it is necessary to operate in the Y position when opened, and in the X position when closed, and depending on the situation, it is necessary to change the operation, and it cannot be said that the operability is very good.

  Therefore, as a configuration that prevents this reverse folding phenomenon and can be closed without reverse folding even if the Y position is pushed sideways, Japanese Patent Laid-Open No. 2000-337014 discloses a configuration in which the door end side of the rail 5 is inclined or curved. Are listed. However, even in this configuration, it is necessary to increase the degree of inclination and the degree of bending in order to make it easier to return in the horizontal direction, and the processing of the rail 5 and other parts becomes complicated and expensive in terms of cost. Has not yet been put into practical use yet.

  Next, as a configuration for obtaining a wider opening, two sets of folding doors are arranged on the left and right as described in JP-A-10-108888, with one opening on the right and the other opening on the left. There are many things, and in this configuration, the opening direction is reversed on the left and right, and it is difficult to think that the above-described operability is so excellent. In addition, a type having a very wide open dimension having a door body continuous over the entire wall surface by a closet or the like is increasing. In this case, a pair of two sheets in a state in which both ends are not held by the pin hinge 7 or the like at both ends. It is a configuration in which multiple sets of folding doors are arranged in series, that is, opening and closing requires multiple operations, and further, a long distance must be moved one by one along the rail 5, which is very operation It is mentioned that the nature is bad.

  Moreover, in the structure which has a large number of doors and obtains a wide open dimension from a state where the whole is connected, either of the two ends of a pair of folding doors is disclosed in JP 2002-339663 A or JP 2002-147102 A. In addition, a child door is arranged, and the child door is rotatably held at the end of the folding door. After folding the folding door, the child door is rotated like a hinged door so that the opening size for three sheets is increased. It has been reported what has gained structure. However, also in the above, the operation must be separately performed as the conventional operation for folding the folding door and the rotation operation for opening and closing the child door.

  Japanese Laid-Open Patent Publication No. 2002-013353 reports that four door bodies are used in which a wide main folding door and a narrow secondary folding door are connected. However, even in the above, the operation is simply connected, and the operation is performed by folding the folding doors in pairs in the same direction, and it is considered that there is no difference from the conventional one.

  In other words, with folding doors, the smaller the width of one door body, the smaller the protrusion at the time of opening, but the smaller the opening dimension for a single opening / closing operation, so there is always more than one to open a wide opening width. Operation is required. Assuming a better folding door here, the folding operation is not limited to a pair of two sheets, but it is configured to fold in a state where three or more sheets are linked together, and more than that, and at the end If the other folding doors can be folded at the same time when the door is folded, a very wide open dimension can be obtained by one operation.

  It is also desirable to realize a smooth closing operation that does not reversely bend even if the vicinity of the projecting portion that is folded and protrudes is pushed in the lateral direction even in the operation at the time of closing from the completely folded state. Furthermore, in both the opening and closing operations, only one operation in the same direction is required. If a plurality of doors can be opened and closed with a series of operations while holding the puller, the operability is further improved. It is thought that it becomes possible to improve.

The present invention has been made to solve the above-mentioned problems, and employs a new mechanism that opens and closes by folding three or more doors in a single operation in a single operation, without increasing the protruding dimension of the door. The primary purpose is to obtain wider open dimensions. Furthermore, in terms of operability, it is possible to eliminate the relatively difficult opening operation, such as moving to the side in anticipation of the timing while pulling towards the front in the first stage, and operating the position that is folded and protrudes forward. However, the second object is to enable smooth operation at the time of closing without reverse folding.
JP-A-10-108888 JP 2000-337014 A JP 2002-013353 A JP 2002-147102 A JP 2002-339663 A JP 2003-0742221 A

  In the present invention, the following technical means are provided to achieve the above object. First, a plurality of doors are provided, and two of them are rotatably connected using a rotating member such as a hinge or a pivot hinge. In addition, the end of one of the two doors is held in a state that can only be rotated on the frame by a pin hinge or the like, and a door or guide member is attached to the door tip side of the other door, A rail is mounted so that it can move laterally along the rail. Up to this stage, it is exactly the same as a normal folding door, and the door held on the frame side is the first door, and the door connected to the side is the second door. Here, in the present invention, a third door is further arranged adjacent to the door end side of the second door.

  Next, two toothed attachment members having arc-shaped teeth and a base member are provided, and the first interlocking device is configured by being rotatably mounted on the base member in a state where the teeth are engaged with each other. At this time, it is assembled using each axis so that the center position of the arcuate teeth becomes the center of rotation. Then, the two toothed attachment members are fixed separately to the second door end and the third door end adjacent to each other. Accordingly, the second door body and the third door body are rotatably connected via the base member, and the second door body rotates together with the one toothed mounting member around the axis center with respect to the base member. The body rotates about the axis with respect to the base member together with the other toothed attachment member, and the second door body and the third door body are interlocked with each other because the teeth mesh with each other.

  A toothed attachment member having arc-shaped teeth; an attachment member; an interlocking arm having an arcuate tooth portion at one end and a receiving connection hole at the other end; and a base member having three axial core insertion holes; The toothed attachment member, the interlocking arm, and the attachment member are rotatably mounted on the same surface on the same surface to constitute the second interlocking device. At this time, the toothed attachment member and the attachment member are mounted on the base member at the respective shaft cores in the same arrangement as the two toothed attachment members described above, and then the teeth of the interlocking arm are connected to the teeth of the toothed attachment member. The interlocking arm is rotatably attached to the base member with the center of the arc-shaped tooth as the axis center in the meshing arrangement. At this time, the attachment member should not interfere with the toothed attachment member and the interlocking arm.

  Next, the third door body is set so that the axial center position of the toothed mounting member is the center of rotation of the third door body, and the axial center position of the mounting member is the center of rotation of the second door body. The toothed attachment member is separately arranged at the end and the attachment member is separately arranged and fixed at the second door end. Further, a receiving member having a long hole is mounted at a position near the rotating member of the second door, and the receiving connecting hole at the other end of the interlocking arm is connected to the receiving member. Accordingly, the second door body and the third door body are rotatably connected via the base member, the second door body rotates with respect to the base member together with the mounting member, and the third door body together with the toothed mounting member. Since the teeth of the interlocking arm and the teeth of the toothed mounting member mesh with each other, the tip of the L-shaped interlocking arm pushes and pulls the receiving member and the second door by the rotation of the third door. Therefore, the second door and the third door will be linked.

  Furthermore, the center position of the rotation of the second door body and the third door body and the position where the first door body is rotatably held on the frame side are set on a straight line, and the rail is arranged on this line. The vertical mounting position of the interlocking device with respect to the door body is not particularly limited, but the upper and lower end positions are suitable, and it may be mounted on both the upper and lower sides or one of them. When mounted on one of the upper and lower sides, attach a connecting member on the other side so that the second door and the third door do not separate and the same rotational movement as the locus by the interlocking device is possible. It is good to leave. Further, the door roller and the guide member that move laterally in the rail are mounted in the vicinity of the vertical position of the central portion of both the shaft attachment teeth of the base member and the attachment member.

  Next, the opening / closing operation of the folding door from the above configuration will be described. First, the front end portion of the third door is opened in a forward direction from a state in which the folded doors in which the first door, the second door, and the third door are arranged in a straight line are closed. Then, the third door attempts to rotate around the axis of the toothed attachment member with respect to the base member. However, the tooth of the toothed attachment member is engaged with another toothed attachment member in the first interlocking device and the tooth of the interlocking arm in the second interlocking device. It rotates in the opposite direction with respect to the door body, and as a result, it becomes an operation of protruding to the near side.

  At this time, the movement of the interlocking device is regulated in the direction along the rail by the doorwheel, and one end of the first door body is held by the frame body by a pin hinge or the like, so the first door body connected by the rotating member And the second door body begin to bend in the V-shape in the front direction, and the operation of moving the door carriage toward the suspension side in the rail is obtained. When the third door is opened to the front, the V-shape of the first and second doors narrows, and the first, second, and third doors are completely folded. The whole folding door will be opened by approaching the hanging base side. Therefore, it is preferable to set the pitch of the teeth so that the third door and the second door always open at the same angle.

  In terms of operability, the operation of opening the third door first is similar to the operation of opening the hinged door, and the interlocking device moves sideways with the doorwheel as the door is opened to some extent. In the final stage of opening to near the degree, the first door body and the second door body are moved in the lateral direction and the moving direction of the door wheel is the same, so a very smooth opening operation can be obtained. Therefore, as an operation member for opening and closing, it is only necessary to attach a pulling handle, a handle or the like in the dug state only to the door end side end portion of the third door body.

  The first interlock is not should be greater diameter teeth than just door body thickness for engaging the two toothed attachment member directly, that would slightly exposed to the outside may be mentioned as a problem. In addition, the ratio of the distance from the axial center of the toothed attachment member to the tooth tip with respect to the width of the door body is reduced, and a very large force is applied to the teeth at the time of opening, leaving room for improvement. Also, if the thickness is increased to increase the strength of the teeth, it will become more noticeable and not good in design. Therefore, if the interlocking device of the second configuration is used, the interlocking arm can be arranged at the back side position with respect to the front of the folding door, the outer periphery of the teeth can be prevented from being exposed to the front side, and the diameter of the arcuate tooth Can be set to some extent, and by setting the larger diameter, the force applied to the teeth during operation can be reduced.

  Next, the closing operation from the state in which the first door, the second door, and the third door are folded substantially at right angles to the rail will be described. In the configuration described above, since the teeth of the third door are always meshed and engaged when rotating in the back direction so as to close the door of the third door, the second door is further rotated to the suspension side. The operation is to be performed, and it cannot be closed as it is. Therefore, in order to close the door, it is necessary to move the interlocking device portion on which the door is mounted along the rail before moving the third door. It is very difficult from the configuration of.

  Therefore, either one tooth part of the two toothed attachment members of the first interlocking device or one tooth part of the toothing attachment member of the second interlocking device or one of the interlocking arm is provided in the angle restriction hole. It is good to change to the structure which has the engagement / disengagement mechanism which consists of an attached gear and a projection part. The projecting portion is generally fan-shaped and fixed at the axial center position of the toothed attachment member or the interlocking arm, and is similarly covered with a gear with an angle-regulating hole having a projecting portion insertion hole having a larger opening angle. Fit in. Further, the projection portion is configured to be able to rotate within an angular range from a position where the projection portion abuts at one end in the projection portion insertion hole to a position where the projection abuts at the other end. That is, in the opening operation of pulling the door end position of the third door body forward, the toothed mounting member and the gear with the angle restricting hole are engaged, so the second door body rotates in the opposite direction and moves forward. In the operation of obtaining a folding action and closing from the folded state, the projection part idles in the gear with the angle restriction hole and the gear with the angle restriction hole does not rotate with respect to the rotation of the third door body. It is better to configure so that only the third door is closed without affecting the movement of the body.

  Therefore, at the time of closing, when the third door is rotated in the closing direction from the folded state, only the third door is idled to a position parallel to the rail, and then the door side in the lateral direction along the rail. By moving the third door body, it is possible to obtain an operation of closing the entire folding door while the second door body and the first door body spread. In addition, the rotation of the second door body and the first door body while rotating at this time causes the rotation of the gear with the angle restricting hole meshing with the toothed mounting member, and when the gear is completely closed, It will naturally return to the position.

  Although the above is a structure which opens and closes three door bodies simultaneously, the structure which opens and closes three or more door bodies continuously is demonstrated. First, when opening and closing four doors in the same direction with one operation, another door is placed on the door side of the third door, and a door cart or door A guide member is provided and inserted into the rail, and the door and the third door are connected by a rotating member such as a hinge. The opening operation in this configuration is not the operation of pulling the door side of the third door to the front, but the conventional operation of pulling the vicinity of the rotary member connecting the door and the third door to the front. Although it becomes the operation | movement similar to a folding door, the operation | movement by which a 1st door body and a 2nd door body are folded by the interlocking apparatus with which the 2nd door body and the 3rd door body were mounted | worn is the same. Further, the same applies to the folding doors having a large number of even numbered sheets, and the interlocking device and the rotating member may be alternately mounted between the door bodies as the number of the doors increases. Therefore, an even number of doors can be opened in the same direction with a single operation.

  In addition, the closing operation in the configuration having an even number of doors is the same as that of a conventional folding door, and the operation of moving the position of the farthest side of the door in the folded state laterally along the rail Therefore, the structure of the engaging / disengaging mechanism having the gear with the angle restricting hole and the protruding portion is not necessary.

  In addition, in the configuration having an odd number of doors of 5 or more, the endmost door that opens to the near side first plays a role corresponding to the third door in terms of function, and the endmost The next door body is connected to the next door body by an interlocking device having an engaging / disengaging mechanism, and the interlocking device having no rotating member and the engaging / disengaging mechanism is alternately attached between the next door bodies in order to interlock the opening. Operation will be obtained. The operation at the time of closing is the same. When the door at the end is rotated in the closing direction, the door is idled to a position parallel to the rail, and then moved along the rail in the direction of the door. Therefore, it is preferable to attach an operation member such as a digging puller only to the door body at the extreme end.

  However, in the configuration with an even number of sheets, there remains a problem of a reverse folding phenomenon that occurs when a position that has been accidentally protruded to the near side at the time of closing remains. In the case of the second interlocking device, there is also a problem that the balance is not good when folded from the opposite direction. Therefore, as a means to further solve this problem, the combination of the toothed mounting member with respect to the base member, the mounting member, and the interlocking arm is turned upside down so that the center position of each rotation does not change with another set of left and right reversed. A third interlocking device configured to be mounted on the base member in a state of being superposed in the direction may be used. The receiving member is also attached to the doors on both sides of the third interlocking device, and the receiving connecting hole of the interlocking arm extending to the left and right is connected to the elongated hole of the receiving member by the connecting pin. This third interlocking device can increase the load resistance of the teeth, and both interlocking arms will be interlocked at the same time even when the door body is operated from the opposite direction. Can be opened and closed in a balanced manner from either the left or right side.

  By configuring as described above, it becomes possible to open and close while folding three or more doors in one operation regardless of whether the total number of doors is odd or even. In addition, it is possible to provide a folding door interlocking opening and closing device having a new excellent mechanism.

  A folding door with a large number of doors, with a rotating member mounted at a position that folds and protrudes forward, and a base member that has a plurality of arcuate teeth at a position that folds and protrudes toward the back. By mounting the interlocking device assembled in a state where the teeth of each other are engaged, it becomes possible to open and close a large number of doors in a single operation.

  In a folding door composed of an odd number of doors, by providing an engagement / disengagement mechanism with a gear with an angle regulating hole and a protruding portion, when opening, the operation of simultaneously folding all doors together is obtained, When closing, it is possible to close the folding door in one operation by interlocking with the folding door by a series of operations in which the outermost door body is idled in the closing direction and moved in the direction of the door tip along the rail.

  With the configuration of the interlocking device of the fourth embodiment, a configuration with good design can be realized without exposing the outer periphery of the arcuate teeth on the front side of the door body. Further, the diameter of the arc-shaped tooth can be arbitrarily set, and the tooth strength can be increased.

  Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1-12 is 1st embodiment of this invention, and has shown the folding door of the structure opened and closed by folding three door bodies by interlocking with the same direction. FIG. 1 is a perspective view of the first embodiment. First, the three doors are referred to as a first door 1, a second door 2, and a third door 3 from the suspension side. The first door 1 has one end portion held on the side surface of the frame 8 so as to be rotatable only by a pin hinge 7 or the like, and the first door 1 and the second door 2 are rotating members 4 such as hinges or pivot hinges. The second door 2 and the third door 3 are connected in a state where both ends are close by the interlocking device a. At this time, the rotating member 4 is preferably arranged on the back side of the folding door. Further, in FIG. 1, the side surface of the frame body 8 shows only the suspension side, but naturally the side surface of the frame body 8 is also provided in the direction of the door tip side of the third door body 3.

And assembled so that it can move in the left-right direction in the rail 5. Furthermore, it arrange | positions so that the edge part position by the side of the frame 8 of the rail 5 may correspond with axial center positions, such as the pin hinge 7 attached to the frame 8 side surface.

  FIG. 1 shows the upper half of the folding door in a form suitable for a closet or the like when viewed from the inside, but naturally the first door 1 is held on the side of the frame 8 by the pin hinge 7 or the like even at the lower position. The rotating member 4 that connects the first door 1 and the second door 2 is also attached at several places in the vertical direction. Here, the second door 2 and the third door 3 are connected by the interlocking device a. However, if the folding door is configured to have the rail 5 in the lower part, the upper interlocking device a includes It is preferable that the door 6 is mounted, a guide member is mounted on the lower interlocking device a, and the rail 5 is moved while being guided both vertically. Moreover, if it is a hanging type folding door which does not have the rail 5 in the lower part, the interlocking device a which does not have a guide member is mounted | worn, or the 2nd door body 2 and the 3rd door body 3 do not isolate | separate in a lower position. Thus, it is preferable to provide a connecting means having the same folding locus as that of the interlocking device a at the lower position.

  FIG. 2 is an exploded perspective view showing the proximity positions of the interlock device a, the door 6, the second door 2, and the third door 3.

An insertion hole 16 is provided, and an attachment screw hole 17 similar to the toothed attachment member 9 is provided on the opposite side.

  FIG. 6 is a plan view of the toothed attachment member 10 with an engagement / disengagement mechanism configured by overlapping the gear 11 with an angle regulating hole on the attachment member 13 with protrusions. The substantially fan-shaped opening angle of the protruding portion 12 of the mounting member 13 with protrusion is set to be about 90 degrees smaller than the opening angle of the substantially fan-shaped protruding portion insertion hole 19 of the gear 11 with the angle regulating hole, and the contact surfaces 18 of each other are The gear 11 with the angle restricting hole is configured to be rotatable within an angle range of about 90 degrees from the position of contact in a state close to one side to the position of contact in a state close to the other. FIG. 7 is a plan view of the base member 14, which is similarly plate-like and has shaft insertion holes 16 provided in two places.

  Next, the toothed mounting member 9 and the toothed mounting member 10 with the engagement / disengagement mechanism are assembled to the shaft core insertion holes 16 at two locations of the base member 14 so as to be rotatable by the shaft core 20 to constitute the interlocking device a. At this time, by arranging the tooth 15 of the toothed attachment member 9 and the gear 11 with the angle restricting hole so as to mesh with each other, the gear 11 with the angle restricting hole is interlocked by the rotation operation of the toothed attaching member 9.

Is fixed to the third door 3 with mounting screws 21. Therefore, the second door body 2 and the third door body 3 are rotatably connected via the base member 14. Further, the door pulley 6 and the guide member may be mounted at the center position of the shafts 20 on the upper surface of the base member 14. FIG. 8 shows that the interlocking device a in the first embodiment is mounted between the second door body 2 and the third door body 3, and the second door 2 and the third door body 3 are aligned and the folding door is closed. FIG. The toothed attachment member 10 with the engagement / disengagement mechanism in a state in which the folding door is closed has the contact surface 18 on the front near side of the projection portion 12 on the contact surface 18 on the front front side of the gear 11 with the angle regulating hole. Both are arranged so as to be in contact with each other. Further, the toothed attachment member 9 and the toothed attachment member 10 with the engagement / disengagement mechanism are reversed in the left-right direction, and the toothed attachment member 9 is attached to the third door 3 and the toothed attachment member 10 with the engagement / disengagement mechanism is attached to the second door 2. The structure fixed to may be sufficient.

  FIG. 9 shows that the interlock device a in the first embodiment is mounted between the second door body 2 and the third door body 3, and the first door body 1 and the second door body 2 are connected by the rotating member 4. It is a top view which shows the locus | trajectory of the whole folding door at the time of open | release by the operation which opens the door-end position of the 3rd door body 3 in this direction from the state in which the folding door was closed. FIG. 9A shows a state in which the folding doors in which the first door 1, the second door 2, and the third door 3 are completely arranged are closed, and the interlocking device a is in the same state as FIG. . At this time, the shaft core 20 of the toothed attachment member 9 and the shaft core 20 of the toothed attachment member 10 with the engagement / disengagement mechanism are arranged in parallel to the rail 5.

  When the door end side of the third door 3 is opened to the front side opposite to the clock from the state of FIG. 9 (a), the mounting member 13 with protrusions also rotates in the same direction. Since the contact surface 18 of the protruding portion 12 is in contact with the contact surface 18 of the gear 11 with the angle restriction hole, the gear 11 with the angle restriction hole is simultaneously rotated in the same direction. As a result, the engaging gear 11 with the angle restricting hole and the tooth 15 of the toothed attachment member 9 are engaged to rotate the second door 2 about the axis 20 of the toothed attachment member 9 clockwise. can get. Therefore, if the pitch of the gear 11 with the angle restricting hole and the pitch of the teeth 15 of the toothed attachment member 9 are matched, the second door 2 rotates forward by the same angle as the third door 3.

  The initial stage of the above operation is the state shown in FIG. 9 (b). Since the second door 2 is connected to the first door 1 by the rotating member 4, the first door 1 and the second door are simultaneously connected. It becomes the operation | movement which the door 2 bends in the front in V shape. At this time, since the suspension side of the first door 1 is held by the frame body 8, the door 6 at the top of the interlocking device a travels in the rail 5 and the entire folding door moves to the suspension side. . Further, when the third door 3 is opened to the front side, the first door 1 and the second door shown in FIG. 9 (f) are obtained through the states of FIGS. 9 (c), 9 (d) and 9 (e). Both the body 2 and the third door body 3 rotate to near 90 degrees with respect to the rail 5, and the folding door can be opened in a fully folded state.

  FIG. 9 (d) shows a state in which the third door 3 is opened by about 45 degrees. In the operations from FIG. 9 (a) to FIG. 9 (d), the third door 3 is suspended with respect to the degree of opening. Although the distance moved to the original side is relatively small, in the operation from FIG. 9D to FIG. 9F, the distance moved to the original side is very large with respect to the degree to which the third door 3 is opened. Become. In other words, as the opening operation, first, the operation is such that it is gradually moved in the lateral direction of the suspension side while pulling to the front side, and therefore the direction of the suspension direction as shown in FIG. It is preferable to wear a puller 22 that has been dug in a shape that requires a finger.

  Moreover, it is good for each door body to make both corners of a front side into R shape, and in the interlock device a front position, the 2nd door body 2 and the 3rd door body 3 rotated to the near direction centering on each axial center 20. Sometimes it is absolutely necessary to prevent the corner portions from coming into contact with each other. When the folding door is closed at the position in front of the rotating member 4, fingers are packed between the first door body 1 and the second door body 2. It is possible to have a role to prevent this.

  Next, the operation of closing the folding door from the fully opened state shown in FIG. In the opening operation described above, the position of the gear 11 with the angle restricting hole with respect to the mounting member 13 with the protrusion is always constant and does not change. Therefore, when the folding door is opened, the toothed mounting member 10 with the detachment mechanism is opened. Even if the toothed attachment member 9 is used instead, no particular problem occurs. However, in the closing operation, in the configuration in which the two toothed attachment members 9 are engaged with each other as described above, the third door 3 is rotated clockwise to close from the fully opened state of FIG. And the engagement of the teeth 15 of the two-tooth mounting member 9 causes the second door 2 to rotate counterclockwise about the axis of the second door 2, that is, the first door 1 and the first door The operation is to simultaneously fold the two-door body 2 further to the hanging base side, and therefore it cannot be closed by an operation of rotating the door end position of the third door body 3 in the closing direction.

  Therefore, an engagement / disengagement mechanism is provided by the gear 11 with the angle restricting hole and the mounting member 13 with the protrusion for the closing operation. Next, the operation of the engagement / disengagement mechanism of the interlocking device a during the closing operation will be described with reference to FIG. . FIG. 10A is an enlarged plan view of the interlocking device a in the open state, which is the same as FIG. 9F. At this time, the projecting portion 12 of the projecting attachment member 13 is in a state in which both contact surfaces 18 are in contact with each other at a position rotated counterclockwise in the projecting portion insertion hole 19 of the gear 11 with the angle regulating hole. Therefore, the attachment member 13 with the protrusion fixed to the third door 3 is in a state in which it can rotate clockwise. Here, when the third door 3 is rotated in the clockwise closing direction from the state of FIG. 10A, the gear 11 with the angle restricting hole engaged with the toothed attachment member 9 does not rotate, As shown in FIG. 10 (b), the third door 3 rotates idly 90 degrees around the shaft core 20 together with the protrusion-attached attachment member 13 having the protrusion 12.

  FIG. 11 is a plan view showing a trajectory during the closing operation. When the door of the third door 3 is operated in the closing direction from the opened state of FIG. 11 (a), as shown in FIG. 11 (b). Only the three-door body 3 is idled to a position parallel to the rail 5. Then, when the third door 3 is moved in the lateral direction along the rail 5, the second door 2 and the first door 1 spread as shown in FIG. 11 (c). It becomes possible to close to the closed state of d). That is, the entire closing operation is a series of operations in which only the third door 3 is once closed by holding the handle 22 at the position of the tip of the third door 3 and then pulled in the horizontal direction as it is to close the whole. Further, since the angle of the second door 2 changes due to the lateral movement from the stage of FIG. 11B, the toothed attachment member 9 also rotates, and the gear 11 with the angle restricting hole is rotated by the teeth of the toothed attachment member 9. The gear 11 with the angle restricting hole 11 returns to the original position in the closed state of FIG.

  By configuring as described above, it is possible to open and close the three doors in conjunction with each other by only one operation with the handle 22 of the third door 3. Further, a ball latch 23 or the like configured to be able to protrude and retract with a spring in the vertical direction as shown in FIG. 12 is mounted on the upper part of the door tip of the third door 3 and is fitted with light force in the rail 5, and the ball is rotated. By making it movable in the left-right direction, a click feeling is obtained in the operation of overcoming the rail 5 at the first stage of opening the third door 3 and coming off to the front, and further, the third door 3 when closed It is possible to clarify the final position that is idle and parallel to the rail 5, and when moving in the lateral direction thereafter, the guide moves along the rail 5, and a sharp operation can be realized.

  The folding door using three doors in the first embodiment has been described above. Next, a configuration in which five or more odd number of doors are opened and closed in conjunction with each other is shown in FIG. Shown in FIG. 13 shows a folding door when five door bodies are used. When an odd number of door bodies are used, the door body at the end farthest from the suspender side and the next door body are attached to a toothed attachment member. 9 and an interlocking device a having an engaging / disengaging mechanism composed of an engaging / disengaging mechanism 10, and a rotating member 4 and two toothed attaching members 9 from between the next door bodies. The interlocking devices a that do not have the engaging / disengaging mechanism configured may be mounted alternately in order.

  The opening and closing operation is exactly the same as in the first embodiment, and when the door is opened, the remaining doors are made into a pair by rotating the pulling handle 22 attached to the end of the door at the end most. Folding and opening interlocking movement is obtained, and when closing the door at the end is rotated in the back direction, the door at the end is idled to a position parallel to the rail 5 and then laterally along the rail 5 The entire folding door can be closed by the operation of moving to.

  Next, a third embodiment of the present invention, which is configured to open and close four or more even numbered doors in conjunction with each other, will be described with reference to FIGS. 14 and 15. FIG. 14 shows a case in which four door bodies are used, and two sets of door bodies are connected to the frame body 8 by a pin hinge 7 or the like and the two door bodies are connected by a rotating member 4 so as to form a pair. It is the structure further connected by the interlocking device a which does not have an engagement / disengagement mechanism. The opening / closing operation at this time is almost the same as that of a conventional folding door, and when opening, the Y-position, which is near the position of the rotating member 4 of the door body that is a pair of door-ends, is pulled forward while pulling forward. With this operation, the first door body and the second door body can be interlocked and folded to the near side, and the four door bodies can be folded and opened simultaneously.

  When the door is closed, an operation is performed in which the vicinity of the X position of the door at the end is moved along the rail 5 toward the door. Therefore, the interlocking device a having the engagement / disengagement mechanism is not necessary in the configuration of the even number of sheets, and the rotation of the most end door body and the next door body in the case of a large number of folding doors having four or more door bodies. It is preferable that the interlocking device a and the rotating member 4 that are connected to each other and have no engagement / disengagement mechanism are alternately mounted in order from the next door. Therefore, it is considered that the configuration having an odd number of doors is superior in operability.

  FIG. 15 is a plan view of a configuration in which the holding of the pin hinge 7 and the like on the frame body 8 side is eliminated from the state of FIG. In terms of directionality when opening, the first embodiment and the second embodiment using an odd number of doors are limited to one direction, but the third embodiment uses an even number of doors. The opening operation can be done from either side. However, to operate from both the left and right directions, pullers 22 are required at both the X and Y positions of the door bodies at both ends of the connected folding door. Therefore, if a pipe-like pull 22 is provided in the width direction as shown in FIG. 15 at the left and right doors, the X and Y positions can be operated with the same pull 22 and can be developed into a left and right double opening configuration. It is.

  However, in the configurations of the first embodiment, the second embodiment, and the third embodiment, the position of the axis 20 of the toothed attachment member 9 is the center of rotation of the second door body 2, and the tooth with the engagement / disengagement mechanism. The position of the axis 20 of the attachment member 10 is the center of rotation of the third door 3, and the positions of both axes 20 are arranged at the center of the thickness of the door. This arrangement is because the adjacent thickness direction surfaces of the third door 3 and the second door 2 do not collide with each other in the fully folded state shown in FIG. 9 (f), and the closing of FIG. 9 (a). It is also a necessary condition for setting so that there is no gap between the two in the state.

  Therefore, in order for the teeth 15 to directly engage with each other while maintaining this condition, it is necessary to set the diameter of the teeth 15 to be larger than the thickness of the door, and as a result, the outer peripheral portion of the teeth 15 protrudes forward from the front of the door. There is a problem that the design is not good. Further, the diameter of the arcuate tooth 15 is limited to some extent by the thickness of the door, and the distance from the axis 20 to the tip of the tooth 15 is inevitably much larger than the distance from the axis 20 to the puller 22. It is also a problem that the teeth 15 become smaller and a very large force is applied to the teeth 15 during operation. The strength of the teeth 15 can be dealt with by increasing the thickness, but in that case, the outer peripheral portion of the teeth 15 will be exposed more and more thickly.

  Therefore, a configuration for further solving the above problems will be described as a fourth embodiment with reference to FIGS. In the fourth embodiment, the interlocking device b having a configuration different from that of the first embodiment, the second embodiment, or the third embodiment is used. The method is exactly the same. 16 to 25 show a configuration having three doors in the fourth embodiment, FIG. 26 shows a configuration having five or more odd-numbered doors, and FIG. 27 shows four or more even-numbered doors. The structure which has the sheet | seat body is shown. FIG. 16 is a perspective view showing the upper half of the folding door according to the fourth embodiment, FIG. 17 is an exploded perspective view of the interlocking device b, and FIG. It is a perspective view of the state assembled to the three-door body 3.

  As shown in FIG. 17, the interlock device b in the fourth embodiment includes a toothed attachment member 9, an attachment member 24, an interlock arm 25, and a base member 14. The toothed attachment member 9 is the same as that of the first embodiment, and the attachment member 24 is plate-like as shown in FIG. 19 and has a shape substantially free of the teeth 15 of the toothed attachment member 9. A mounting screw hole 17 is provided on the other side of the hole 16.

  As shown in FIG. 20, the interlocking arm 25 has a plate shape and is bent in an L shape. The interlocking arm 25 has an arcuate tooth 15 on one side, a shaft insertion hole 16 is provided at the center of the arcuate tooth 15, and the other side. Is provided with a receiving connection hole 26 at its tip in a long and elongated shape. Here, the folding door having three doors requires a mechanism for the third door 3 to idle in the closing operation as in the first embodiment. Therefore, either the interlocking arm 25 or the toothed attachment member 9 is required. One side may be provided with the same engagement / disengagement mechanism as described above. FIG. 21 is a plan view of the interlocking arm 25 having a structure including an engaging / disengaging mechanism including the gear 11 with the angle restricting hole and the protruding portion 12.

  The base member 14 is also plate-shaped as shown in FIG. 22, and is provided with shaft core insertion holes 16 at three locations. The three axial core insertion holes 16 are arranged in a substantially triangular shape, and two axial core insertion holes 16 are arranged on a line parallel to the rail 5, and the two axial core insertion holes 16 are arranged. The toothed attachment member 9 and the attachment member 24 are assembled to be rotatable about the respective shaft cores 20. Furthermore, the shaft core insertion hole 16 located in the other back direction of the base member 14 and the shaft core insertion hole 16 of the interlocking arm 25 are connected by another shaft core 20. At this time, the gear 11 with the angle restricting hole of the interlocking arm 25 and the tooth 15 of the toothed attachment member 9 are arranged so as to mesh with each other so that the gear 11 with the angle restricting hole and the attachment member 24 do not interfere with each other. As described above, the interlocking device b in the fourth embodiment is configured by assembling the toothed mounting member 9, the mounting member 24, and the interlocking arm 25 having the engagement / disengagement mechanism to the base member 14. Further, the door pulley 6 and the guide member may be mounted in the vicinity of an intermediate position between the two shaft core insertion holes 16 parallel to the rail 5 of the base member 14.

  FIG. 23 is a plan view showing a state in which the interlocking device b in the fourth embodiment is attached to the second door body 2 and the third door body 3, both door bodies are aligned, and the folding door is closed. is there. At this time, the shaft core 20 of the toothed mounting member 9 and the shaft core 20 of the mounting member 24 are arranged symmetrically with respect to the proximity point of the second door body 2 and the third door body 3, The shaft core 20 is located on the back side thereof, so that the receiving connection hole 26 at the tip of the interlocking arm 25 bent in an L shape in the direction of the second door 2 is in the vicinity of the position where it contacts the back surface of the second door 2. Configure it to

  Further, as shown in FIG. 18, the upper surface of the second door 2 and the upper surface of the third door 3 are dug by the thickness of the toothed mounting member 9 and the mounting member 24, and the toothed mounting member 9 is moved by the mounting screw 21. The attachment member 24 is fixed to the second door 2 to the three door 3. Further, a receiving member 27 having a long hole 28 is provided and fixed at a position near the rotating member 4 on the back surface of the second door 2, and the receiving connecting hole 26 of the interlocking arm 25 and the long hole 28 of the receiving member 27 are provided. The connecting pin 29 is inserted to connect both.

  As shown in FIG. 23, in the interlocking device b in the fourth embodiment, the center of rotation of the second door body 2 and the third door body 3 is not at the center position of the thickness of the door body but at the back side. Therefore, the outer peripheral portion of the tooth 15 is not exposed to the front side, and it is not necessary to largely cut out the front surface of the door body, which is superior to the first embodiment in terms of design. Further, in the fourth embodiment, as shown in FIG. 24, it is possible to further arrange the center positions of the rotation of the second door body 2 and the third door body 3 in the back direction. The diameter of the arc-shaped tooth 15 and the diameter of the gear 11 with the angle restricting hole can be set larger, so that the force applied to the tooth 15 during the opening / closing operation can be reduced and the strength of each tooth 15 itself can be increased. It becomes possible.

  FIG. 25 is a plan view showing a trajectory when a folding door having three doors in the fourth embodiment is opened. FIG. 25A shows a state in which the folding door is closed. When the pulling handle 22 is rotated in the forward direction, the toothed attachment member 9 is simultaneously rotated together with the third door body 3. At this time, the tooth 15 of the toothed attachment member 9 and the gear 11 with the angle restricting hole are engaged with each other, and the engagement / disengagement mechanism provided in the interlocking arm 25 is the contact of the protruding portion 12 as in the first embodiment. The surface 18 and the contact surface 18 of the gear 11 with the angle restricting hole are in contact with each other in a direction to rotate, and therefore the interlocking arm 25 rotates in the opposite direction. Here, the receiving connection hole 26 of the interlocking arm 25 and the receiving member 27 fixed to the second door body 2 are connected, so that the interlocking arm 25 pushes the second door body 2 in the forward direction. As shown in (b), the first door 1 and the second door 2 begin to bend into a V shape. When the third door 3 is further opened, it moves from the state of FIG. 25 (c) to the position of FIG. 25 (f) through the state of FIG. 25 (e), and the folding door can be folded and opened.

  In the fourth embodiment, the interlocking device b is arranged so as to jump out farther than the thickness of the door, so it is suitable for folding doors with front and back like a closet, but both sides can be seen like a room partition. Not suitable for configuration. The interlocking arm 25 is formed in an L shape so that it does not interfere with the rear corner portion of the second door 2 on the interlocking device b side in the folded state shown in FIG. Therefore, in the stage of FIG. 25 (f), the interlocking arm 25 is sandwiched between the second door body 2 and the first door body 1, and there is a phenomenon that the folding arm 25 cannot be fully folded. Therefore, it suffices to dig a wide part where the interlocking arm 25 on the upper part of the second door 2 moves by opening / closing operation. And the second door 2 and the first door 1 can be completely folded until they are parallel to each other.

  The closing operation is the same as that of the first embodiment. Although not shown, when the third door 3 is rotated in the back direction, the third door 3 is caused to idle by the gear 11 with the angle restricting hole and the protruding portion 12. The whole folding door can be closed by rotating to a position parallel to the rail 5 and then moving laterally along the rail 5.

  FIG. 26 is a plan view of a folding door having five doors in the configuration of the fourth embodiment, and is the same as that of the second embodiment except for the interlocking device b, and the door on the most tip side and the next door. The body is connected by an interlocking device b having an engagement / disengagement mechanism, and the rotation device 4 and the interlocking device b having no engagement / disengagement mechanism are sequentially mounted between the next door bodies. The same applies to a folding door having an odd number of doors of 5 or more.

  FIG. 27 is a plan view of a folding door having an even number of doors in the configuration of the fourth embodiment, and is the same as that of the third embodiment except for the interlocking device b. Therefore, the interlocking device b has an engagement / disengagement mechanism. It may be of a configuration that does not. Further, in the case of interlocking the four door bodies, if the holding of the frame body 8 by the pin hinge 7 or the like is removed, the opening / closing operation can be performed from both the left and right directions as in the third embodiment. However, in the interlocking device b in the fourth embodiment, the L-shaped interlocking arm itself has some directionality, and there is a point that the balance is poor when operated from the opposite direction. Therefore, a configuration in which the force applied to the teeth 15 is more uniform and balanced will be described as a fifth embodiment with reference to FIGS. 28 and 29. FIG.

  FIG. 28 is an exploded perspective view of the interlock device c in the fifth embodiment, and FIG. 29 is a plan view of a state in which the interlock device c in the fifth embodiment is mounted on a folding door having four door bodies. . As shown in FIG. 28, the interlocking device c in the fifth embodiment has another configuration of the toothed mounting member 9, the mounting member 24, and the interlocking arm 25 with respect to the base member 14 of the interlocking device b in the fourth embodiment. In order to prevent the center positions of the respective rotations from changing in the arrangement reversed to the left and right of the set, they are mounted on the base member 14 in a state of being overlapped in the vertical direction.

  In addition, the receiving member 27 is attached to the left and right doors of the interlocking device a, and the receiving connecting hole 26 of the interlocking arm 25 extending to both the left and right is connected to the long hole 28 of the receiving member 27 with a connecting pin 29. By configuring in this way, the upper and lower two sets of teeth 15 are simultaneously engaged in a well-balanced manner, and the load resistance against the teeth 15 can be doubled. In the fourth embodiment and the fifth embodiment, since the teeth 15 are not exposed to the front side of the door body, deep digging is possible in the upper portion of the door body, and the thickness of the toothed attachment member 9 and the interlocking arm 25 is increased. If it is made, it can be set as a still stronger structure.

  Further, another configuration of the interlocking device d will be described with reference to FIG. 30 as a sixth embodiment. In the sixth embodiment, as shown in FIG. 30, two toothed attachment members 9 and two separate gear members 30 are provided, and the teeth 15 are sequentially meshed with each other via the base member 14 and interlocked. The arrangement and the opening / closing operation with respect to the door are exactly the same as those of the above-described embodiments. Further, although not shown in the figure, in the case of an odd number of folding doors, if the interlocking device d having the engagement / disengagement mechanism is attached only to the end door and the next door in the same manner as described above, Good. Furthermore, if the shaft core 20 of the toothed attachment member 9 is arranged as far as possible in the door body and interlocked with the gear member 30 having a relatively large diameter, it is considered that a high-strength configuration can be achieved.
