The interlocking sliding door device of the present invention is, for example, operated in three or more pieces. When a plurality of sliding doors or two sliding doors stored in the sliding door storage space are operated, when one sliding door is started to move, the other sliding doors move in conjunction with the moving sliding door. In the example shown below, a structure in which three sliding doors are slid and linked is described. However, the present invention is also applicable to two sliding doors (for example, a sliding sliding door in which two sliding doors are accommodated in the sliding door storage portion). The structure in which the device or the like is interlocked may be applied to a structure in which four or more sliding doors are interlocked as will be described later. Further, the present invention is not limited to the embodiments described below.

<First embodiment>

As shown in Fig. 1, the linked sliding door device 1 of the present embodiment includes a sliding door D1 (first sliding door), a sliding door D2 (second sliding door), and a sliding door D3 (third sliding door). The sliding door D1, the sliding door D2, and the sliding door D3 (hereinafter, the sliding door D1, the sliding door D2, and the sliding door D3 are collectively referred to as the sliding door D) are disposed substantially parallel to each other. The sliding door D1, the sliding door D2, and the sliding door D3 can lock the door opening having a predetermined width, and in a state where the door opening is open, the three sliding doors D are in a state of being overlapped with each other as shown in FIG. In a state in which the three sliding doors D are overlapped, the sliding door D1 is disposed in the center in the thickness direction X (see FIG. 1) of the sliding door D, and is sandwiched by the sliding door D2 and the sliding door D3, adjacent to the sliding door D1. On both sides of the thickness direction X of the sliding door D1 are the sliding door D2 and the sliding door D3.

The three sliding doors D are configured to slide relative to each other. In the present embodiment, as shown in FIG. 2, the sliding door D is configured to be disposed along the rail R1 provided on the upper side of the sliding door D, and is disposed at the lower portion. The side rails R2 slide separately. Specifically, in the present embodiment, as shown in FIGS. 1 and 2, a guide member G provided at the upper end of the sliding door D and engaged with the rail R1 is guided. In the present embodiment, the guide member G is provided with a cylinder as shown in FIGS. 1 and 2 . The portion Ga and a part of the shaft portion Gb housed in the cylindrical portion Ga. The upper end of the shaft portion Gb is provided with an engaging portion Gc that engages with the rail R1. When the sliding door D slides, the engaging portion Gc is guided by the groove of the rail R1, and the sliding door D slides. The lower end side of the shaft portion Gb is housed in the cylindrical portion Ga, and a potential energy member such as a spring that imparts potential energy to the inside of the groove (upward) of the shaft portion Gb in the cylindrical portion Ga is provided in the cylindrical portion Ga ( Not shown). When the sliding door D is attached to the rail R1, when the engaging portion Gc is pressed against the groove of the rail R1, the shaft portion Gb is pressed into the cylindrical portion Ga against the imparting ability of the potential energy member. When the sliding door D is attached to the rail R1, the shaft portion Gb protrudes toward the groove of the rail R1 by imparting the potential energy imparted by the potential energy member. Thereby, the sliding door D can easily attach and detach the rail R1.

In the lower portion of the sliding door D, in the present embodiment, as shown in Fig. 2, a door wheel W that rotates on the rail R2 is provided. The door wheel W can use a well-known door wheel. Further, the sliding door D may be slidably movable relative to each other, and the guiding mechanism of the sliding door D such as the rails R1 and R2 for guiding the sliding door D to slide the sliding door D is not limited to the embodiment. Shower. For example, a slide roller and a track on which the slide roller can be rotated may be provided on the upper side of the sliding door D, or a protruding portion that is engaged with the groove-shaped upper and lower rails may be provided above and below the sliding door D. Also, the sliding door D may be a hanging door.

Further, as shown in FIGS. 1 and 3, the interlocking mechanism for interlocking the sliding doors D includes an upper end side US side or a lower end surface LS side of the sliding door D1 (first sliding door), and is located at the sliding door D1. a pair of direction changing members 2a, 2b which are disposed apart from each other in the sliding direction Y (refer to FIG. 1); a transmission member 3 which is wound around the pair of direction changing members 2a, 2b in an annular shape; and is attached to the sliding door D2 ( 2nd sliding door), A joint member 4a that is directly or indirectly coupled to the transmission member 3. Further, the connection mechanism includes a second coupling member 4b that is also attached to the sliding door D3 (third sliding door) and coupled to the transmission member 3. In addition, hereinafter, the connecting member 4a and the second connecting member 4b are collectively referred to as a connecting member 4.

As shown in the schematic diagrams of Figs. 4(a) to 4(c), the interlocking mechanism is configured such that when one sliding door is slid, the other sliding door is slid in conjunction with each other. Specifically, when the sliding door D2 adjacent to the sliding door D1 is slid in the right direction in FIG. 4(a), the connecting member 4a attached to the sliding door D2 will respond to the sliding of the sliding door D2 from FIG. 4 ( The initial position shown in a) moves in the sliding direction (right direction) as shown in Fig. 4(b). When the connecting member 4a moves to the right side, the transmission member 3 to which the connecting member 4a is attached is rotated counterclockwise in FIG. 4(b) as the connecting member 4a moves. On the other hand, the sliding door D3 is coupled to the transmission member 3 by the second coupling member 4b. However, since the weight of the sliding door D3 and the transmission member 3 are rotated counterclockwise, the sliding door D3 is directed to the left of the paper. The potential energy is given and the sliding door D3 does not move. Since the length of the transmission member 3 from the connection between the transmission member 3 and the coupling member 4a to the junction between the transmission member 3 and the second coupling member 4b is constant, the transmission member 3 is rotated counterclockwise, the sliding door D1 slides in the same direction as the sliding door D2, that is, toward the right side (see FIGS. 4(b) and 4(c)). Thereby, the opening can be blocked by the sliding door D1, the sliding door D2 and the sliding door D3. When the sliding door D2 is opened from the state shown in FIG. 4(c), the sliding door D1 is similarly changed to the sliding door D2 and changes to the state of FIGS. 4(b) and 4(a). In addition, even if the sliding door D3 is a predetermined type of structure (wall portion) such as a wall, the sliding door D1 and the sliding door D2 can be interlocked by providing the second connecting member 4b or the like on the structure.

The transmission member 3 used in the connection mechanism is a power transmission member that is coupled to the connection member 4 and that is guided and rotated by the pair of direction changing members 2a and 2b in order to realize the above-described interlocking of the sliding door D. In the present embodiment, as shown in FIGS. 1 and 3, the transmission member 3 is a toothed belt having a rack portion 3a (hereinafter sometimes referred to as a toothed belt 3), but it may be rotated as long as it is possible The power transmission is realized, and the interlocking of the sliding door D described above is not limited to the toothed belt. For example, it may be only a strip-shaped body such as a belt, a long member such as a steel wire, a rope, or a wire. Further, the transmission member 3 may be a transmission member that has been previously formed into an endless ring, but as will be described later, by connecting the ends of one or two or more linear elongated members that are not formed into a ring, And form a ring.

As shown in FIGS. 1 to 3, the transmission member 3 is wound around a pair of direction changing members 2a and 2b. The direction changing members 2a, 2b guide the transmission member 3 so that the transmission member 3 can be rotated. In the present embodiment, the direction changing members 2a and 2b are attached to the upper end surface US of the sliding door D1. Further, the direction changing members 2a, 2b may be provided on the lower end surface LS of the sliding door D1. In addition, in the case of the "upper end surface US side" and the "lower end surface LS side" of the sliding door D1, the portion where the direction changing members 2a and 2b are attached is the upper end surface US or the lower end surface of the sliding door D1. In addition to the LS, for example, after the direction changing members 2a, 2b are mounted, a cover or the like covering the direction changing members 2a, 2b, a new face or the like is formed above the direction changing members 2a, 2b, on the upper end face US or The direction changing members 2a and 2b are provided in the vicinity of the lower end surface LS.

The direction changing members 2a and 2b may be members that rotate when the transmission member 3 is rotatably guided, or may be members that do not rotate. However, in the present embodiment, the teeth that rotate about the vertical axis are used. Roller (below, Sometimes referred to as tooth rolls 2a, 2b). As shown in FIGS. 1 and 2, the toothed roller is formed with a gear on the outer circumference to guide the toothed belt 3. In the present embodiment, the flange portion 21 is provided on the upper portion of the tooth rolls 2a and 2b as shown in Fig. 1 . The flange portion 21 is formed so as to protrude in the horizontal direction from the outer circumference of the circle formed by the tooth tips of the tooth rolls 2a and 2b beyond the tooth tips of the tooth rolls 2a and 2b. As a result of the experiment, the toothed belt 3 moves in the axial direction of the toothed rolls 2a and 2b as it rotates in accordance with the opening and closing operation of the sliding door D, that is, in the present embodiment, it moves upward, and is convex. The edge portion 21 can restrict the upward movement of the toothed belt 3. Further, in the present embodiment, the flange portion 21 is a disk-shaped flange portion 21 having a diameter larger than the diameter of the circle formed by the tooth tips of the tooth rolls 2a and 2b. However, the flange portion 21 is It is not limited to a disk shape, and may have other shapes such as a rectangular shape.

The transmission member 3 provided on the sliding door D1 is directly or indirectly coupled to the connecting member 4, and is connected to a sliding door adjacent to the sliding door provided with the transmission member 3. In the present embodiment, the transmission member 3 is coupled to the coupling member 4, and the sliding door D1 is connected to the adjacent sliding door D2 and the sliding door D3. The connecting member 4 is attached to another sliding door (or a structure such as a wall portion) adjacent to one sliding door provided with the transmission member 3. That is, in the present embodiment, the connecting member 4a is attached to the sliding door D2, and the second connecting member 4b is attached to the sliding door D3. In the present embodiment, as shown in FIGS. 1 and 3, the connecting member 4a and the second connecting member 4b are fixed to the upper end surface US of the sliding door D2 and the sliding door D3 by screws, respectively. However, if the connecting members 4a, 4b can be directly or indirectly attached to the transmission member 3, the mounting positions of the sliding door D2 and the sliding door D3 are not limited to the upper end surface US, and may be attached to the side of the sliding door D ( The opposite side of the sliding door D) is the upper end side of the US side. Also, when the transmission member 3 is disposed on the lower end side of the sliding door D, The structural member may also be provided on the lower end face LS side. The attachment means of the connection member 4 is not limited to the screw, and other well-known attachment means, such as an adhesive agent, can be used.

In the interlocking sliding door device 1 of the present embodiment, the connecting member 4 and the transmission member 3 are configured to be coupled to each other by a magnetic force. As described above, when the sliding door D is attached to the opening blocked by the sliding door D by the rails R1, R2, etc., it is extremely difficult to mount two or three sliding doors D at a time. Therefore, it is virtually impossible to mount the transmission member 3 and the joint member 4 before the sliding door D is mounted to the opening, and the sliding member D must be mounted one by one after the opening to mount the transmission member 3 and the joint member. 4. Further, since the transmission member 3 and the coupling member 4 are provided on the upper end side or the lower end side of the sliding door D, there is only a very limited space where the transmission member 3 and the coupling member 4 are coupled. At this time, it is extremely difficult to install with a screw. When the direction of the mounting screw is the vertical direction, there is no gap into which the screwdriver can enter, a special tool is required, and the connecting member 4 is directed to the transmission member 3 in the horizontal direction. When the screw is attached and locked, the transmission member 3 and the connecting member 4 must be held by hand, and the connecting member 4 must be attached while being supported without being displaced from the transmission member 3. Thus, since the installation work of the transmission member 3 and the joint member 4 on the site is already very complicated, the space for installation is very limited, and in addition, the work is performed at the upper end of the sliding door D. So it will make the work more difficult. Further, such an operation is required not only at the time of installation but also when the sliding door D is removed by sweeping or repairing, and in the conventional configuration, it is impossible to easily remove the sliding door D one by one.

In the present embodiment, the magnetic transmission transmission member 3 and the connection are connected. The structural members 4 are coupled to each other, whereby the sliding door D can be easily attached and detached when the sliding door D is attached and detached, and the workability on the site can be greatly improved. The mounting operation of the sliding door D (the mounting order of the sliding door D is not particularly limited) will be described in detail. For example, when the sliding door D1 is first attached to the opening, the sliding door D2 is attached. Then, in the present embodiment, the connecting member 4a is opposed to the connecting portion with the transmission member 3 by the magnetic force, and the connecting member 4a and the transmission member 3 are attracted to each other at the joint portion by the magnetic attraction force, which is very simple. Link the ground. Then, after the sliding door D3 is attached, the second connecting member 4b is also opposed to the connecting portion with the transmission member 3 by the magnetic force, and the second connecting member 4b and the transmission member 3 are caused by the magnetic attraction force. The joints are very simple to connect. Since the transmission member 3 and the connection member 4 can be connected by the magnetic force adsorption force as described above, even a narrow work space can be easily connected, and it is not necessary to lock a work space such as a screw, and the side can be omitted. It is troublesome to lock the screw while the member is not offset. When it is desired to disassemble one of the sliding doors D, since it is only necessary to overcome the magnetic force to separate the transmission member 3 from the coupling member 4, the disassembly is also very simple.

In the present embodiment, as shown in FIGS. 1 and 3, the transmission member 3 and the connection member 4 are connected to each other via the connection member 5 provided at least at the longitudinal direction of the transmission member 3. The connected member 5 may be integrally provided to the transmission member 3 in advance, or may be a member attached to the transmission member 3. Further, in the present embodiment, the transmission member 3 and the connection member 4 are indirectly coupled through the connection member 5, but the transmission member 3 may be directly connected to the magnetic transmission member in which the magnetic powder is mixed, for example. For example, the connecting members 4 having magnets are coupled.

As shown in FIGS. 5(a) and 5(b), the connecting member 4 and the connected member 5 connected to the connecting member 4 are provided with a magnet M, and the other has a magnetic body that is adsorbed by the magnet M (for example, When the connecting member 4 and the connected member 5 are opposed to each other, the connecting member 4 and the second magnet are adsorbed and coupled by a magnetic force. In the present embodiment, as shown in FIGS. 5(a) and 5(b), the magnet M is placed on the side of the connecting member 5, and the connecting member 4 is formed by a magnetic body. However, a magnet may be provided on the side of the connecting member 4, and a magnetic body may be provided on the side of the connecting member 5, or both the connecting member 4 and the connected member 5 may have magnets. Further, in the present embodiment, the connecting member 4 is formed of a magnetic material, but one of the members (the connecting member 4 or the connected member 5) to which the magnetic body is to be provided has a magnetic body, and for example, it may be The magnetic body to which the magnet is adsorbed is attached to a part of the connecting member 4 made of resin. Further, the magnet (or the magnetic body) may be directly attached to, for example, the transmission member 3 having a surface on which the magnet (or magnetic body) can be mounted, such as the belt-shaped transmission member 3.

The connected member 5 is previously attached to the transmission member 3 before the sliding door D is attached, and is coupled to the connecting member 4 by a magnetic force when the sliding door D is attached. As described above, when one of the connecting members 4 is provided with a magnet and the other is provided with a magnetic body or a second magnet that is attracted by the magnet, the sliding door D can be made as shown in FIGS. 5( a ) and 5 ( b ). The connection between the connecting member 4 and the connected member 5 is performed by sliding to the position where the connecting member 4 is opposed to the connected member 5 or by a simple operation such as turning the transmission member 3. That is, as shown in FIG. 5(a), even if the position between the connecting member 4 and the member to be joined 5 is shifted in the sliding direction Y of the sliding door D, the sliding door D can be slid, or Rotating the transmission member 3 when being moved by the coupling member 5 to the pair of the coupling members 4 In the position of the direction, the magnetic members can be attracted to each other, and the connection between the connecting member 4 and the connected member 5 can be easily performed.

Further, the connected member 5 of the present embodiment includes the fitting recess 5a as shown in FIG. 6(a), and the connecting member 4 includes a fitting portion that fits the fitting recess 5a. Thereby, when the connecting member 4 faces the connected member 5, as shown in FIGS. 1 and 7, the fitting portion is fitted to the fitting recess 5a. As shown in Fig. 5 (a), (b), and Fig. 6 (a), for example, when the sliding door D2 is moved in the sliding direction Y, the fitting recessed portion 5a is attached to the fitting portion (the suction surface of the connecting member 4 to be described later). 42. The position where the end portion of the sliding direction Y abuts with reference to Fig. 7) has wall portions W1, W2. Therefore, even after the connection member 4 is engaged with the connection member 5, even if the sliding door D moves in the sliding direction Y, the connecting member 4 and the connected member 5 are applied with a force that is displaced in the sliding direction Y, and the force is not released. The connection between the connecting member 4 and the connected member 5 is obtained. In the present embodiment, the fitting recess 5a is provided in the connected member 5, and the fitting portion is provided on the connecting member 4 side. However, the fitting portion 5 may be provided with the fitting portion and connected. A fitting recess is formed on the side of the member 4.

As will be described in more detail with respect to the member to be joined 5 of the present embodiment, as shown in FIGS. 6(a) and 6(b), the base portion 51 and the engagement of the rack portion 3a including the toothed belt 3 are engaged. The engaging member 52 of the portion 52a. The base portion 51 is a member having a substantially rectangular parallelepiped shape, and the pair of wall portions W1, W2 protrude toward the opposite sliding door, and a fitting recess portion 5a is formed between the wall portions W1 and W2. In the base portion 51, in the present embodiment, the magnet M is attached, and the connecting member 4 can be adsorbed by the magnetic force. Further, as described above, when a magnet or the like is provided on the side of the connecting member 4, a magnetic body or a second magnet is provided in the base portion 51. In the present embodiment, the base portion 51 is as shown in Fig. 6(a). In addition to the magnet M, the screw hole 5b is formed in the center, and the magnet M is embedded in the upper side of the screw hole 5b. However, the position where the screw hole 5b or the magnet M is buried is not limited to the illustrated position. Further, the base portion 51 has a groove portion 5c (refer to FIG. 7) corresponding to the width of the toothed belt 3 on the opposing surface of the base portion 51 facing the engaging member 52, and the toothed belt 3 is fitted into the groove portion. 5c makes it easier to install the toothed belt 3.

In the present embodiment, the engaging member 52 is a plate-like member connected to the base portion 51 as shown in Figs. 6(a), (b) and 7 and is formed to correspond to the rack portion 3a of the toothed belt 3. The engaging portion 52a of the shape. In the present embodiment, a plurality of engaging portions 52a are provided (four engaging portions 52a are shown in FIGS. 6(a) and (b)), and the adjacent engaging portions 52a are in the rack portion. 3a are set at intervals corresponding to the intervals in the long direction. The rack portion 3a enters the engaging portion 52a, whereby relative movement between the joined member 5 and the toothed belt 3 in the sliding direction Y at the time of mounting can be prevented.

The screw hole 5b provided in the base portion 51 is provided to penetrate through the base portion 51, and a screw hole 5d is also formed in the engaging member 52 that engages with the rack portion 3a of the toothed belt 3 (see Figs. 6(a) and (b). )), after the toothed belt 3 is sandwiched by the base portion 51 and the engaging member 52, the screw is locked into the screw holes 5b, 5d, and the base portion 51 and the engaging member 52 are fixed, so that the toothed belt 3 can be The joint member 5 is fixed. At this time, when the engaging member 52 is formed of a magnetic body, in a state where the toothed belt 3 is sandwiched between the engaging member 52 and the base portion 51, since the engaging member 52 is attracted by the magnet M of the base portion 51, Therefore, the workability when installing the screw can be improved. At this time, the magnet M is configured such that the magnetic force can be applied to both sides of the thickness direction X of the sliding door D in the base portion 51.

Further, the method of connecting the base portion 51 and the engaging member 52 is not limited to the illustrated method. For example, the base portion 51 and the engaging member 52 may be integrally connected through the hinge portion, and when the toothed belt 3 is sandwiched, the engaging member 52 is rotated about the base portion 51, and the toothed belt 3 is attached to the toothed belt 3 After the base portion 51, the engaging member 52 is rotated about the base portion 51 by the toothed belt 3, and the engaging member 52 is fixed to the base portion 51 by the engaging claw or the like while the toothed belt 3 has been pinched.

Further, in the present embodiment, the toothed belt 3 is composed of two linear belt members 31 and 32 which do not form a ring as shown in Figs. 1 and 6 (a) and (b). At this time, as shown in FIGS. 6(a) and 6(b), the rack portion 3a formed at one end of the belt member 31 of the toothed belt 3 is inserted into the engaging portion 52a of the engaging member 52, and is formed in another The rack portion 3a of one end of the belt member 32 is similarly inserted into the engaging portion 52a of the engaging member 52, and the belt member 31, 32 is sandwiched by the base portion 51 and the engaging member 52, so that the two belt members 31 can be made. 32 is connected to the member to be joined 5 . This advantage is as follows: When forming the ring of the toothed belt 3, a strip of a sufficient length, which is not looped, can be cut into a length corresponding to the width of the desired sliding door D, which can be never looped. One strip is formed into a ring-shaped toothed belt. For example, in the case where the annular toothed belt is prepared in advance, in order to form a ring of a length corresponding to the width in the sliding direction Y of the sliding door D, it is first ordered to be manufactured with the factory, and linked from the consumer. When the sliding door is placed, it will take a lot of time until the sliding door is actually installed. However, the toothed belt 3 is sheared as described above, and the end portions of the belt members 31 and 32 are joined to the portion to be joined by the joint member 5, whereby the length adjustment can be easily performed on the spot, so that the sliding door D can be quickly installed. . Moreover, due to the connection of the ends of the belt members 31, 32, The connection between the belt members 31 and 32 and the connection between the joint member 5 and the toothed belt 3 are simultaneously performed, so that the work is also very simple. Further, in the present embodiment, the two linear belt members 31 and 32 are connected. However, the end portions of the one straight belt may be connected to each other at the portion to be joined to form a loop.

Further, in the present embodiment, as shown in Fig. 7, the connecting member 4 is provided with a fixing portion 41 fixed to the sliding door D2 and the upper end surface US of the sliding door D3, and is slightly vertical with respect to the upper end surface US of the sliding door D2. The ground surface extends, the adsorption surface 42 that is mutually adsorbed by the magnetic force of the connected member, and the extending portion 43 that extends slightly perpendicularly from the adsorption surface 42 toward the sliding door D1 side. The fixing portion 41 is attached to the sliding door D by a fixing means such as a screw. The adsorption surface 42 is a surface that is adsorbed by the magnetic force to the member to be joined 5, and in the present embodiment, it also functions as a fitting portion that fits the fitting recess 5a. Further, as described above, the extension member 43 floats upward toward the upper side due to the action of the rotation of the transmission member 3, so the extension portion 43 extends above the transmission member 3, thereby preventing the transmission member 3's up.

Further, in the modification of the embodiment, as shown in Figs. 8(a) to 8(c), the base portion 51 of the connected member 5 may include an insertion portion into which the extending portion 43 of the connecting member 4 (4a) can be inserted. 53. The insertion portion 53 is a through hole formed to penetrate the base portion 51 in FIGS. 8( a ) to 8 ( c ). However, the insertion portion 53 does not necessarily need to penetrate the base portion 51 as long as the extension portion 43 can be inserted. When the connecting member 4 and the connected member 5 are coupled, as shown in FIG. 8( c ), the extending portion 43 is inserted into the insertion portion 53 . Thereby, the movement in the vertical direction between the joint member 4 and the jointed member 5 can be restricted, and the joint between the joint member 4 and the jointed member 5 can be prevented. Get rid of. Engagement between the insertion portion 53 and the extension portion 43, particularly when the sliding door D has been locked, the end surface of the sliding door D (for example, the end surface on the right side of the sliding door D2 in FIG. 1 or the left side of the sliding door D3) The end face, etc.) will come in handy when hitting the wall with great force. That is, when the sliding door D is locked, when the end surface of the sliding door D is strongly struck against the wall or the like, because of the impact of the sliding door D against the wall, or when the sliding door D rebounds from the wall The impact (for example, an elastic buffer such as an impact that absorbs an impact when the sliding door D is struck on the end surface of the sliding door D), or other impact such as when a person hits the sliding door D, etc., in the connecting member 4 and the joined member 5 Sometimes, the force to the direction of disengagement is applied. Therefore, in this modification, in addition to the attraction force by the magnet between the coupling member 4 and the member to be joined 5, and the fitting between the fitting portion and the fitting recess 5a in the sliding direction, Limit the relative movement in the vertical direction. Therefore, even when a force is applied to the sliding door D, even if a force that relatively moves between the connecting member 4 and the connected member 5 in the vertical direction is applied, the insertion portion 53 can be inserted into the insertion portion 53 by the extension portion 43. The upper and lower wall portions 53a and 53b of the insertion portion 53 prevent the connection member 5 from being separated from the connection member 4. Therefore, in this modification, the connection member 4 and the to-be-connected member 5 can be connected more firmly, and when the sliding door D is latched, etc., when it receives an impact, the connection member 4 and the to-be-joining member 5 can be reliably prevented from being detached. .

The members 4c are moved closer to each other in the sliding direction Y (refer to FIG. 11). Similarly, when the sliding door D moves from the open state to the closed state, the fourth connecting member 4d and the fifth connecting member 4e move toward each other in the sliding direction Y. At this time, the end portion of the connecting member 4a on the blocking direction side and the end portion of the third connecting member 4c on the opening direction side are in contact as shown in FIG. 11, and in FIG. 11, the adjacent sliding door D is sliding. The overlap A in the direction Y becomes larger. Since the overlap A of the sliding door D in the sliding direction Y does not sufficiently utilize the length of the sliding direction Y of the sliding door D, it is necessary to reduce the overlap A as much as possible.

In the present embodiment, as shown in FIGS. 12 and 13, the connecting member 4a includes a fixing portion 41 that is fixed to the sliding door D12, and a cutting portion that extends from the fixing portion 41 and is cut in the thickness direction X of the sliding door D. The cross section is a U-shaped portion 44 which is slightly inverted U-shaped. The fixing portion 41 is a portion to which the connecting member 4a is attached to the sliding door D12 and fixed, and is fixed to the sliding door D12 by a known fixing means such as a screw as shown in FIG. In the present embodiment, the fixing portion 41 has an insertion hole through which a screw is inserted into the flat member. A U-shaped portion 44 which is slightly inverted U-shaped is extended from the fixing portion 41.

Further, in the present embodiment, in addition to the U-shaped portion 44, the second horizontal portion 45 that extends slightly perpendicularly from the lower end of the second vertical portion 44c to the second vertical portion 44c is provided. The vertical portion 44a passes through the inner side of the ring of the second transmission member 33 and extends from the upper end surface US of the sliding door 12. In addition, the shape of the U-shaped portion 44 that extends in the U-shaped portion 44 from the fixing portion 41 and extends toward the side of the connecting member 5 and then extends downward is not limited to that shown in FIG. The shape. For example, in the present embodiment, the vertical portion 44a, the horizontal portion 44b, the second vertical portion 44c, and the like are formed in a flat shape, but may be curved or may be extended at an angle different from the angle shown.

On the other hand, the third connecting member 4c that moves closer to the connecting member 4a when the sliding door D is closed, as shown in FIGS. 12 and 13, includes a fixing portion 41c attached to the sliding door D11, and a fixing portion The 41c extends, and the cross section cut in the thickness direction of the sliding door D is an L-shaped portion 46 having a substantially L shape. The fixing portion 41c is a portion to which the third connecting member 4c is attached to the sliding door D11 and fixed, and is fixed to the sliding door D11 by a known fixing means such as a screw as shown in FIG.

The fixed portion 41c has a horizontal portion 46a that horizontally extends toward the third connected member 50c, and a vertical portion 46b that extends slightly perpendicularly from the horizontal portion 46a. In the present embodiment, in addition to the L-shaped portion 46, a second vertical portion 47 extending from the upper end of the vertical portion 46b in a substantially vertical direction is provided.

According to this configuration, as shown in FIGS. 12 and 14, the connecting member 4a and the third connecting member 4c are configured to move in the sliding direction Y to be uniform. At the position, one of the L-shaped portions 46 (the vertical portion 46b of the L-shaped portion 46) enters the inside of the U-shaped portion 44 (the vertical portion 44a, the horizontal portion 44b, and the second vertical portion of the U-shaped portion 44). The part enclosed by 44c). Therefore, as shown in Fig. 14, when the sliding door D is slid in the blocking direction, and the connecting member 4a and the third connecting member 4c move closer to each other, the L-shaped portion 46 of the third connecting member 4c is submerged in a U shape. The connecting member 4a and the third connecting member 4c do not interfere with each other inside the portion 44. Therefore, in addition to the effects similar to those of the first embodiment and the second embodiment, the overlap A in the sliding direction Y of the sliding door D can be made small.

In the present embodiment, the connecting member 4a has the U-shaped portion 44, and the third connecting member 4c has the L-shaped portion 46. However, the connecting member 4a may have the L-shaped portion 46, The third connecting member 4c has a U-shaped portion 44, and the L-shaped portion 46 of the connecting member 4a enters the U-shaped portion 44 of the third connecting member 4c.

Further, the fourth connecting member 4d and the fifth connecting member 4e may have the same configuration as the connecting member 4a and the third connecting member 4c, respectively. Further, the shape of the fourth connecting member 4d and the fifth connecting member 4e may be reversed.

<Fourth embodiment>
