Description

  The present invention relates to a sliding door interlocking device that interlocks other sliding doors in accordance with the opening / closing operation of one sliding door when opening and closing an opening of a structure such as a building or furniture with a plurality of sliding doors, and the sliding door interlocking device. The present invention relates to a receiving member provided and a sliding door device provided with the sliding door interlocking device.

  Conventionally, in an opening in a building or the like, there are cases where a plurality of sliding doors are used to close the opening for effective use of a frontage. When multiple sliding doors are provided in this way, it is troublesome to open and close each sliding door, etc. An interlocking device may be installed.

  The present applicant has also proposed a sliding door interlocking device that is easy to install (see Patent Document 1).

  Specifically, this sliding door interlocking device is attached to the lower end of one sliding door along the opening / closing direction of the sliding door and the lower end of the adjacent sliding door or adjacent wall adjacent to this one sliding door. Receiving member.

  The apparatus body is surrounded by a casing extending in the opening / closing direction of the sliding door, pulleys disposed at both ends in the longitudinal direction inside the casing, an endless wire spanned between the pulleys, and the endless wire. A pair of sliders attached to the endless wire at a point-symmetrical position with respect to the center of the range, and a plate-like tip attached to each of the sliders and extending vertically along the front surface of the sliding door. A pair of connecting members, and each plate-like tip engages with each receiving member of the adjacent sliding door or the adjacent wall, thereby opening and closing one sliding door in which the device body is embedded in conjunction with the opening / closing operation of the adjacent sliding door It is supposed to be.

  In the sliding door interlocking device described in Patent Document 1, the receiving member is configured so that the slider and the receiving member can be easily connected via a connecting member including a plate-shaped tip.

  Specifically, the receiving member is a fixed portion fixed to the surface of the adjacent sliding door or the adjacent wall portion, and is suspended from the fixed portion in a state separated from each other in the sliding door opening / closing direction. Has a pair of restraining portions for restraining the plate-like tip portion in the sliding door opening / closing direction by being arranged in a tight state. Each restraining portion is configured to be elastically deformable in a direction away from an adjacent sliding door or the like to which the fixing portion is fixed, and is inclined inward in the sliding door opening / closing direction toward the adjacent sliding door in a portion opposite to the opposite side. An inclined surface is provided.

  Therefore, according to this sliding door interlocking device, in order to connect the receiving member and the plate-like tip portion, the receiving member and the plate-like tip portion are relatively brought close to each other along the sliding door opening / closing direction, thereby restricting the receiving member. When the plate-like tip is brought into contact with the inclined surface provided on the plate, the restraining portion is bent and deformed in the direction away from the fixed object by the inclined surface along with the contact, and the plate-like tip passes through the restraining portion. The restraining part returns to the original state and restrains the plate-like tip part in the sliding door opening / closing direction together with the other restraining part.

  Specifically, the inner surfaces of the pair of restraining portions in the sliding door opening / closing direction are in surface contact with the both sides of the sliding end of the plate-shaped tip in a vertically long rectangular shape, thereby causing the plate-shaped leading end to slide in the sliding door opening / closing direction. Is supposed to be binding.

  Therefore, the slider and the receiving member can be easily connected because the receiving member and the plate-shaped front end can be connected only by relatively approaching them along the sliding door sliding direction. Is advantageous.

  By the way, there are many cases where the opening of the structure is not originally a strict rectangular shape. For example, the door frame disposed in the opening may have some distortion in the initial state. In addition, it is known that such distortion changes, albeit slightly, due to the surrounding environment such as humidity and aging degradation. For reasons such as adjusting the height of the sliding door in order to eliminate such untightening due to distortion, the sliding door may be tilted about the front-rear direction although it is only a few.

  Accordingly, when the conventional interlocking device is installed for a plurality of sliding doors that open and close the opening in which such distortion occurs, the tilt angle of the sliding doors is relatively different depending on the sliding position of each sliding door. In some cases, this tilt occurs as resistance in the opening / closing operation of the sliding door. Specifically, in the conventional sliding door interlocking device, since the plate-like tip portion is constrained in a tight state in the receiving member, the longitudinal direction of one of the sliding doors is set as an axis through these receiving member and the plate-like tip portion. An external force based on the tilt may interact with the other sliding door to generate resistance in the sliding door opening / closing operation.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a sliding door interlocking device, a receiving member, and a sliding door device that can smoothly open and close the sliding door.

  In order to solve the above problems, a sliding door interlocking device according to the present invention has a slider that slides along the opening / closing direction of the sliding door, and a plate-like connecting portion that is connected to the slider and extends in the vertical direction along the sliding door. A sliding door interlocking device comprising: a interlocking device main body attached to the sliding door; and a receiving member that is attached to an adjacent sliding door or an adjacent wall portion adjacent to the sliding door and engages with the plate-like connecting portion. Sliding door opening / closing of the plate-like connecting portion by contacting a base attached to the adjacent sliding door or the adjacent wall portion and a linear portion protruding from the base and extending in the front-rear direction with respect to an end surface of the plate-like connecting portion in the sliding door opening / closing direction And a pair of restraining protrusions that restrain movement in each direction. Here, “contact with a linear part” means a linear part having a certain width, for example, a rectangular shape in which the length in the front-rear direction is set longer than the length in the height direction, in addition to the case of line contact. It is a concept that includes the case of contact at a part. The “adjacent wall portion” is a concept that includes a wall portion as a holding portion for a receiving member fixed to a floor portion, in addition to the wall portion itself adjacent to one sliding door.

  According to this invention, the receiving member is a base that is attached to the adjacent sliding door or the adjacent wall portion, and a linear portion that protrudes from the base and extends in the front-rear direction with respect to the end surface of the plate-like connecting portion in the sliding door opening / closing direction. And a pair of restraining projections that restrain the movement of the plate-like connecting portion in each direction of opening and closing of the sliding door, so that the sliding door tilts or tilts about the front-rear direction based on the distortion of the opening of the structure. Even in this case, the plate-like connecting portion can be rotated about the linear portion in relation to the restraining protrusion, and the plate-like connecting portion and the receiving member based on the tilting of the sliding door by this rotation. It is possible to absorb the change in the relative positional relationship with the. For this reason, the external force based on the tilting of the sliding door can be released, and the sliding door can be opened and closed smoothly.

  In the present invention, the specific configuration of the base of the receiving member is not particularly limited, and is, for example, configured only by a plate-like fixing portion that is fixed to the adjacent sliding door or the adjacent wall portion and overlaps the plate-like connecting portion. A pair of hanging parts extending in the vertical direction from a block-like fixing part and its front-rear front end. However, the base body is fixed to the adjacent sliding door or the adjacent wall portion and overlaps with the plate-like connecting portion, and the base portion is connected to the fixing portion. On the other hand, it is preferable to include a facing portion provided at a facing position sandwiching the plate-like connecting portion in the front-rear direction. In this case, the restraining projection protrudes from the fixed portion or the facing portion to the other side. Is preferred

  If comprised in this way, since a plate-shaped connection part can be substantially held from the front-back direction by the said fixing | fixed part and an opposing part, it is effective that this plate-shaped connection part detaches | leaves unexpectedly with respect to a receiving member. Can be prevented. In addition, since the fixed portion overlaps with the plate-like connecting portion, the plate-like connecting portion does not come into contact with the adjacent sliding door or the like with the opening / closing operation of the sliding door, and the adjacent sliding door or the like is not damaged. In addition, since the restraining protrusion is formed so as to protrude from the fixed portion or the facing portion to the other side, the restraining protrusion can be easily configured, and the gap between the fixing portion and the facing portion is a plate. It can comprise as a rotation permissible space of a shape connection part, and the space concerned can be set up simply.

  In this case, the receiving member may have the fixed portion, the facing portion, and the restraining protrusion as main components, but the holding portion that sandwiches both the fixed portion and the facing portion from the front and rear. Is preferably further provided.

  If comprised in this way, since a fixing | fixed part and an opposing part are pinched | interposed from the front and back by a clamping part, the separation in the front-back direction of a fixing | fixed part and an opposing part can be suppressed effectively, and, thereby, a fixed part and an opposing part It is possible to effectively suppress the separation of the plate-like connecting portion from being unintentionally released.

  Moreover, when providing a clamping part in this way, it does not specifically limit about the specific structure of the said clamping part, A U-shaped member is inserted from one direction (for example, sliding door opening / closing direction one side or upper direction). The holding portion may be configured to hold the fixed portion and the facing portion. The holding portion includes a main wall portion disposed on the surface side of the facing portion, and the fixed portion from both sides of the main wall portion in the sliding door opening / closing direction. A pair of side wall portions extending toward the side, and engaging pieces that extend from the front end portions of the respective side wall portions toward the inside in the sliding door opening / closing direction and engage with the fixing portions, and each of the side wall portions has a vertical direction It is preferable that the height position is arranged at a position at least partially overlapping the plate-like connecting portion.

  If comprised in this way, while being able to manufacture a clamping part simply, by holding a fixed part and an opposing part from both sides of a sliding door opening-and-closing direction by a clamping part, separation of both parts is controlled reliably. it can. In addition, since each side wall portion is disposed at a position at least partially overlapping the plate-like connecting portion with respect to the height position in the vertical direction, the fixing portion and the facing portion are unexpectedly separated from each other based on an impact or the like. Even when the restraint of the plate-like connecting portion by the restraining protrusion is released, each side wall portion serves as a barrier and can reliably prevent the release of the engagement between the plate-like connecting portion and the receiving member.

  Further, in the present invention, the specific shape of the restraining protrusion is not particularly limited, and the outer edge shape in the cross section having the normal direction in the front-rear direction may be a polygonal shape including a triangular shape. It is preferably configured in an arc shape including a semi-ellipse and an arc shape. Specifically, it is preferable that the constraining protrusion is configured as an arcuate surface in which each side end surface on the plate-like connecting portion side has an axial center in the front-rear direction.

  If comprised in this way, even if a plate-shaped connection part rotates, etc. by sliding door tilting, this restraint protrusion and plate-shaped connection part are stabilized by a linear part by the arc-shaped surface of a restriction protrusion. Thus, the sliding door can be smoothly opened and closed.

  Further, in the present invention, the specific configuration of the restraining protrusion is not particularly limited, but the restraining protrusion is protruded from the inside of the sliding door opening / closing direction toward the inside of the sliding door opening / closing direction. It is preferable to have an inclined surface inclined in the direction side.

  If comprised in this way, since a plate-shaped connection part can get over a restraint protrusion along an inclined surface by sliding a plate-shaped connection part and a receiving member relatively, a plate-shaped connection part and restraint. The plate-like connecting portion and the receiving member can be easily connected simply by aligning the height position with the protrusion and sliding relatively.

  In addition, regarding the specific configuration of the base of the receiving member, for example, the base of the receiving member includes a fixed main body fixed to the adjacent sliding door or the adjacent wall, and a downward direction from both ends of the fixed main body in the sliding door opening / closing direction. And a pair of fixed leg portions between which the plate-like connecting portion is disposed, and in this case, the restraining protrusion is configured to open and close the sliding door of the fixed leg portion. It is preferable to protrude toward the inside in the sliding door opening / closing direction on the inner side surface in the direction.

  If comprised in this way, a base | substrate can be comprised simply and cost suppression can be aimed at. Moreover, the rotation permission space of the plate-like connecting portion can be easily adjusted by adjusting the protrusion amount of the restraining protrusion.

  In this case, the receiving member further includes a cover member that straddles the pair of fixed legs along the sliding door opening and closing direction, and both ends are fixed to the adjacent sliding door or the adjacent wall, It is preferable that the height position in the vertical direction is arranged at a position overlapping at least partly with the plate-like connecting portion.

  That is, when the base is provided with a fixed main body portion and a fixed leg portion, there is a concern about a decrease in strength in the fixed leg portion. Therefore, the cover member straddles the fixed leg portion and both ends are directly adjacent sliding doors or adjacent walls. By fixing to the portion, the strength of the fixed leg portion can be improved. In addition, since the cover member is disposed at a position at least partially overlapping the plate-like connecting portion in the vertical height position, the plate-like connecting portion arranged between the pair of fixed legs is unexpected. Even if it is about to jump out between these fixed leg portions, this cover member becomes a barrier, and it is possible to reliably prevent unexpected engagement between the two.

  The specific shape of the cover member is not particularly limited, but the cover main wall portion disposed on the surface side of the fixed leg portion from the fixed main body portion of the receiving member, and the cover main wall portion A pair of cover side walls extending from both sides of the sliding door opening / closing direction toward the adjacent sliding door or the adjacent wall, and fixed to the adjacent sliding door or adjacent wall extending from the end of each cover side wall toward the outside in the sliding door opening / closing direction. It is preferable to provide the fixing flange portion to improve the strength of the substrate.

  In order to solve the above-described problem, a receiving member in a sliding door interlocking device according to another invention includes a slider that slides along the opening / closing direction of the sliding door, and a plate that is connected to the slider and extends in the vertical direction along the sliding door.

In this embodiment, the click protrusion 232c has a substantially rectangular parallelepiped shape, and engages / disengages with an engagement hole 222a (described later) of the sandwich cover 22 to detachably hold the sandwich cover 22. Further, the click protrusion 232c can be clicked by engagement / disengagement with the engagement hole 222a, and the holding cover 22 can be attached to an appropriate position of the receiving body 21. The shape of the click protrusion 232c is not particularly limited. For example, in order to improve the engagement / disengagement work with the engagement hole 222a, the click protrusion 232c is formed in a semi-cylindrical shape or hemispherical shape having an axial center in the front-rear direction. May be.

  On the other hand, the facing portion 24 is a substantially rectangular plate-like body extending downward from the front end edge of the bulging portion 232 in the fixing portion 23, and the vertical height position of the lower end is the lower end of the overlapping portion 231 of the fixing portion 23. It is comprised so that it may correspond to the height position of. As a result, the facing portion 24 is disposed at a position facing the overlapping portion 231 of the fixing portion 23 in the front-rear direction, and has a substantially U shape in side view together with the fixing portion 23.

  In the present embodiment, the front surface of the facing portion 24 is set to be flush with the front surface of the bulging portion 232. On the other hand, a bulging guide portion 24 a bulging backward toward the inner side in the left-right direction is provided at the center in the left-right direction on the rear surface of the facing portion 24 (the surface facing the overlapping portion 231). The tip portion 15c is guided to the overlapping portion 231 side, and when the plate-like tip portion 15c is overlapped with the overlapping portion 231, the plate-like tip portion 15c moves in a direction away from the overlapping portion 231. It is supposed to be suppressed. The bulging height in the front-rear direction of the bulging guide portion 24a is appropriately set according to the position of the protruding tip surface of the restraining projection 25, and in this embodiment, the rear tip surface (bulging tip) of the bulging guide portion 24a. (Surface) is set so as to be substantially at the same height as the protruding front end surface of the restraining protrusion 25 (see FIG. 7D).

  Further, the opposing portion 24 is configured as an inclined guide surface 24b whose left and right end faces are inclined inward in the left-right direction toward the rear, and the plate-like tip portion 15c is not affected even when it interferes with the plate-like tip portion 15c of the connecting member 15. It is configured to move backward. Further, the facing portion 24 is slightly lower in the center when viewed from the front, and an access hole 24c for accessing the mounting hole 235 is provided in a penetrating state at a position facing the mounting hole 235 of the overlapping portion 231. Yes.

  As shown in FIGS. 6 and 7 (e), a pair of restraining protrusions 25 is provided to protrude forward (opposite part 24 side) at the left and right ends of the fixing part 23, more specifically at the lower end part of the overlapping part 231. ing.

  The constraining projection 25 is configured such that each side end surface on the inner side in the left-right direction is curved. Specifically, the constraining protrusion 25 is configured as a semi-cylindrical surface 25a having a substantially semi-oval shape in a front view and each side end surface on the inner side in the left-right direction having an axis C in the front-rear direction. For this reason, the inner end face of the restraining protrusion 25 is in line contact with the side end face in the opening / closing direction of the plate-like tip 15c of the connecting member 15, more specifically, a linear portion 25b extending in the front-rear direction (FIG. 7D). Contact).

  Further, the protruding amount of the restraining protrusion 25 is appropriately set in consideration of the thickness of the plate-like tip portion 15c of the connecting member 15, and is preferably set to be equal to or larger than the thickness of the plate-like tip portion 15c. In the present embodiment, the thickness is set to be equal to the thickness of the plate-like tip portion 15c. An end face on the outer side in the left-right direction (opening / closing direction) of each restricting protrusion 25 is configured as an inclined guide surface 25c that is inclined forward (in the protruding direction of the restricting protrusion 25) toward the inner side in the left-right direction. The plate-like tip 15c of the connecting member 15 is bent forward along the inclined guide surface 25c and guided between the pair of restraining protrusions 25. In the present embodiment, the inclined guide surface 25c of the constraining protrusion 25 is set to be flush with the inclined guide surface 231a of the overlapping portion 231 in the state in which the inclination angle is matched. The inclination angles of 25c and 231a may be changed on each surface, and need not be constant on each guide surface 25c and 231a.

  Next, the sandwiching cover 22 will be described. 8A and 8B are various views showing the sandwiching cover, where FIG. 8A is a front view, FIG. 8B is a side view, FIG. 8C is a plan view, and FIG. 8D is a bottom view.

  The sandwiching cover 22 sandwiches both the fixing portion 23 and the facing portion 24 of the receiving body 21 from the front and rear. Thereby, the sandwiching cover 22 plays a role of suppressing the movement of the facing portion 24 in the separating direction (forward) with respect to the fixed portion 23, and as a result, the restraining protrusion 25 and the plate-like tip portion 15 c of the connecting member 15. It is effectively prevented that the engagement state is released.

  Specifically, the sandwiching cover 22 has a substantially rectangular main wall portion 221 disposed on the front surface side of the facing portion 24, and toward the rear (fixed target side) from both lateral edges of the main wall portion 221. A pair of side wall portions 222 that extend, an engagement piece 223 that extends inward in the left-right direction from the front end (rear end) of the side wall portion 222, and a flap portion 224 that extends rearward from the upper end edge of the main wall portion 221. The receiving body 21 is held from the front side. In the present embodiment, the sandwiching cover 22 is formed by bending a metal plate having a rigidity that can fulfill the above-mentioned role.

  The main wall portion 221 has a substantially rectangular shape in front view set larger than the front surface of the receiving body 21, and is disposed so as to overlap the facing portion 24 of the receiving body 21. When the main wall portion 221 is attached to the receiving body 21, cover access holes 221 a for accessing the attachment holes 235, 236 are provided at locations corresponding to the attachment holes 235, 236 of the fixing portion 23. 221b is penetrated. In the present embodiment, the cover access holes 221b corresponding to the pair of mounting holes 236 of the overlapping portion 231 may be provided individually corresponding to the mounting holes 236, but in the present embodiment, As an oval extending in the left-right direction, it is provided integrally with the pair of left and right mounting holes 236.

  The side wall portion 222 extends to the lower end of the main wall portion 221 while being spaced apart from the flap portion 224 by a predetermined length, and is disposed along the side surface of the receiving body 21. The separation length from the flap portion 224 is set as appropriate so that a tool such as a screwdriver can be inserted into the gap, and is configured so that the tool can be inserted through the gap 222c and the holding cover 22 can be removed from the receiving body 21. Yes.

  In the present embodiment, the side wall portion 222 is disposed over substantially the entire vertical direction of the left and right side surfaces of the receiving body 21, so that the side wall portion 222 is positioned in the vertical direction when the clamping cover 22 is attached to the receiving body 21. Is set so as to partially overlap the height position of the plate-like tip portion 15c of the connecting member 15.

  The side wall 222 is engaged with the click protrusion 232c of the fixing portion 23 in a state in which the holding cover 22 is attached to the main body 21, that is, in an attachment state in which the lower end of the main wall portion 221 coincides with the lower end of the receiving main body 21. An engaging hole 222a is formed. The side wall 222 is provided with a second engagement hole 222b that engages with the click protrusion 232c of the fixing portion 23 at a predetermined height position from the lower end thereof. The predetermined height is set based on the length from the click protrusion 232c of the fixing portion 23 to the lower end of the bulging portion 232, and is set lower than the reference length. In the present embodiment, the predetermined height is set so as to substantially match the reference length.

  With this setting, the gap between the facing portion 24 and the overlapping portion 231 of the fixing portion 23 is left and right in a state where the click protrusion 232c of the fixing portion 23 is engaged with the second engagement hole 222b. The plate-shaped front end portion 15c of the connecting member 15 can be engaged and connected to the receiving body 21 as will be described later. For this reason, even if it does not bother to completely remove the sandwiching cover 22 from the main body 21, there is an advantage that the connecting operation can be performed and workability can be improved.

  The engaging piece 223 is configured as a flap piece having a predetermined width disposed along the back surface of the receiving body 21. In the present embodiment, the engagement piece 223 is extended from the upper end of the side wall portion 222 to a position corresponding to the upper end of the restraining projection 25 of the receiving body 21 in the attached state of the clamping cover 22 to the receiving body 21. ing. Thus, the reason why the engagement piece 223 is not extended to the lower end of the side wall portion 222 is that the cover engagement groove 233 extends to the back side of the restraint projection 25 to reduce the rigidity of the restraint projection 25. It is for suppressing.

  As described above, the flap portion 224 is provided to remove the clamping cover 22 from the main body 21 and has a width, rigidity, and the like appropriately set so that a tool or the like can be hooked. For this reason, the flap part 224 is arrange | positioned in the position spaced apart from the top surface of the receiving main body 21 in the mounting state of the clamping cover 22. FIG. In the present embodiment, the width of the flap portion 224 is set so as to correspond to the thickness of the receiving body 21.

  The attachment of the sliding door interlocking device 1 configured as described above will be described with reference to FIGS. 1 and 2, and the connection between the interlocking device main body 1a and the receiving member 20 will be described with reference to FIGS. . FIG. 9 is a side view showing the receiving body 21 attached to the fixing objects W and D1. FIGS. 10A and 10B are explanatory views showing a state in which the holding cover 22 is attached to the receiving body 21, where FIG. 10A is a front view and FIG. 10B is a side view. 11 is an explanatory view showing a process of attaching the plate-like tip portion 15c of the connecting member 15 to the receiving body 21, and FIG. 12 shows the connection state of the receiving body 21 and the plate-like tip portion 15c of the connecting member 15 facing each other. It is a front view shown in the state where a portion is omitted.

  First, as shown in FIG.1 and FIG.2, the sliding door interlocking apparatus main body 1a is accommodated and fixed in the accommodation groove part D21 of the sliding door D1. Specifically, the interlocking device main body 1a is fixed with a fixing tool (not shown) such as a screw in the storage groove D21 in such a manner that the plate-like tip portions 15c of the pair of connecting members 15 are respectively along the front and rear surfaces of the sliding door D1. To do.

  Next, the receiving body 21 of the receiving member 20 is attached to the fixing objects W and D2. Specifically, as shown in FIG. 1, when the sliding doors D <b> 1 and D <b> 2 are in a fully closed state, the plate-like distal end portion 15 c of the connecting member 15 is a lower end portion of the facing surface of the adjacent wall portion W that overlaps the sliding door D <b> 1. The receiving body 21 of the wall-side receiving member 20 </ b> A is fixed at a height position that overlaps the overlapping portion 231 of the receiving member 20. In addition, when the sliding doors D1 and D2 are in the fully closed state, the receiving body 21 of the door-side receiving member 20B is at the same height as the wall-side receiving member 20A, at the lower end of the facing surface of the sliding door D2 that overlaps the sliding door D1. To fix. As shown in FIG. 9, each receiving body 21 is attached by superimposing the fixing portions 23 on the fixing objects W and D <b> 1 and fixing them with fixing tools such as screws through the attachment holes 235 and 236.

  Subsequently, the holding cover 22 is temporarily attached to the receiving body 21. That is, the sandwiching cover 22 is inserted into the receiving body 21 from above. For this insertion, the engaging piece 223 of the sandwiching cover 22 is slid into the cover engaging groove 233 of the receiving body 21 from above. Then, the click projection 232 c of the receiving body 21 is fitted into the second engagement hole 222 b of the sandwiching cover 22, and the sandwiching cover 22 is temporarily attached to the body 21.

  Next, the sliding door interlocking device main body 1 a and each receiving member 20 are connected via the connecting member 15. That is, each connecting member 15 and each receiving body 21 are connected to each other.

  Specifically, for example, when the plate-like tip portion 15c of the connecting member 15 is connected to the receiving body 21 of the wall-side receiving member 20A, the sliding door D1 is slid in the opening / closing direction with respect to the adjacent wall portion W. By this sliding, the plate-like tip portion 15c moves in a direction relatively close to the receiving body 21 (FIG. 11A, white arrow), and the slide tip surface of the plate-like tip portion 15c is the receiving body 21. The overlapping portion 231 or the inclined guide surfaces 231a and 25c of the restraining projection 25 are in contact with each other (FIG. 11B). It should be noted that which of the inclined guide surfaces 231a and 25c is in contact with the sliding doors D1 and D2 and the space between the adjacent walls W in the front-rear direction and the like. Further, depending on the size of the gap in the front-rear direction, the plate-like distal end portion 15 c may come into contact with the inclined guide surface 24 b in the facing portion 24 of the receiving body 21.

  When the sliding door D1 is further slid relative to this state, the plate-like tip portion 15c is elastically deformed forward (sliding door D1 side) along the inclined guide surfaces 231a and 25c, and along with this elastic deformation, It abuts against the facing portion 24 of the receiving body 21. Thereafter, the plate-like tip portion 15 c slides while sliding on the front surface of the restraining projection 25 and the bulging guide portion 24 a of the facing portion 24. The facing portion 24 is elastically deformed in a direction away from the overlapping portion 231 (in the present embodiment, forward) in accordance with the sliding contact of the plate-like tip portion 15c (FIGS. 11C and 11D).

  The plate-like front end portion 15c and the facing portion 24 are elastically recovered when the slide rear end edge of the plate-like front end portion 15c passes through the restraining protrusion 25. As a result, the plate-like tip 15c is disposed between the restricting protrusions 25 in the left-right direction, and the restricting protrusion 25 abuts on the end face in the opening / closing direction (left-right direction) at the linear portion 25b. The movement in each direction of sliding door opening and closing is restricted (FIG. 12). Further, in this state, the facing portion 24 is disposed at a position facing the overlapping portion 231 of the fixing portion 23 with the plate-like tip portion 15c sandwiched therebetween, and the plate-like tip portion 15c includes the overlapping portion 231, the facing portion 24 and the restraint portion. It is substantially held by the protrusion 25. Further, the bulging guide portion 24a of the facing portion 24 is disposed at a position where its front-rear direction front end surface (rear surface) is in contact with or close to the plate-shaped front end portion 15c, and suppresses movement of the plate-shaped front end portion 15c in the front-rear direction. It is supposed to be.

  Thus, the restraining projection 25 is configured as an inclined guide surface 25c in which each surface outside the sliding door opening / closing direction is inclined toward the inside of the sliding door opening / closing direction toward the protruding direction of the restraining projection, so Since the plate-like tip 15c can get over the restraining protrusion 25 along the inclined guide surface 25c by relatively sliding the 15c and the receiving member 20, the plate-like tip 15c and the restraining protrusion 25 are The plate-like tip portion 15c and the receiving member 20 can be easily connected simply by aligning their height positions and sliding them relatively.

  After connecting the connecting member 15 to the receiving body 21, the holding cover 22 that is temporarily attached to the receiving body 21 is received and attached to the body 21. That is, as described above, the sandwiching cover 22 is in a temporarily mounted state in which the click protrusion 232c of the receiving body 21 is engaged with the second engagement hole 222b (see FIG. 10). By pushing the clamping cover 22 downward from this temporarily mounted state, the engagement state between the second engagement hole 222b and the click projection 232c is released, and then the click projection 232c enters the engagement hole 222a of the clamping cover 22. Are engaged, and the sandwiching cover 22 is attached to the receiving body 21.

  In addition, it cannot be overemphasized that the door side receiving member 20B is attached to the sliding door D1 similarly to the wall side receiving member 20A.

  In this state, the overlapping portion 231 and the facing portion 24 of the fixed portion 23 are sandwiched from the front and rear by the sandwiching cover 22 on both sides in the sliding door opening / closing direction, and the movement of the overlapping portion 231 and the facing portion 24 in the front-rear direction is effective. Regulated and reliably. For this reason, it can suppress effectively and reliably that the superposition | polymerization part 231 and the opposing part 24 of the fixing | fixed part 23 separate, and the restraint state of the plate-shaped front-end | tip part 15c is cancelled | released unexpectedly. Moreover, since the sandwiching cover 22 includes the main wall portion 221, the pair of side wall portions 222, and the pair of engaging pieces 223, the sandwiching cover 22 can be easily manufactured. In addition, each side wall portion 222 of the sandwiching cover 22 is disposed at a position that partially overlaps the plate-shaped tip portion 15c with respect to the height position in the vertical direction. Even when the portion 231 and the facing portion 24 move away from each other and the restraint of the plate-like connecting portion by the restraining projection 25 is released, each side wall portion 222 becomes a barrier and the plate-like tip portion 15c and the receiving member ( In particular, the disengagement with the receiving body 21) can be reliably prevented.

  In the sliding door interlocking device 1 attached in this way, for example, based on the distortion of the opening of the building, the sliding door D2 is inclined relative to the adjacent sliding door D1 and the adjacent wall W with the front-rear direction as an axis. Accordingly, even when the plate-like tip portion 15c of the connecting member 15 is tilted with respect to the receiving body 21 with the front-rear direction as an axis (two-dot chain line in FIG. 12), the plate-like tip portion 15c is a linear portion of the restraining projection 25. 25b can be rotated about the axis, and by this rotation, a change in the relative positional relationship between the plate-like tip portion 15c and the receiving body 21 based on the tilt of the sliding door D1 can be absorbed (see FIG. 12). . For this reason, the external force based on the tilt of the sliding door D1 can be released, and the sliding door D1, and thus the sliding door D2 can be opened and closed smoothly.

  In addition, since each side end surface of the restraining projection 25 on the plate-like tip portion 15c side is configured as an arcuate surface having an axial center in the front-rear direction, the plate-like tip portion 15c is rotated as the sliding door D1 tilts. Even in this case, the constraining protrusion 25 and the plate-like tip 15c can be stably brought into contact with each other at the linear portion 25b by the arc-shaped surface of the constraining protrusion 25, and thereby the smooth sliding door D1, The opening / closing operation of D2 can be performed.

  In addition, the overlapping portion 231, the facing portion 24, and the restraining protrusion 25 of the fixing portion 23 can substantially hold the plate-like tip portion 15 c from the front-rear and left-right directions, so that the plate-like tip portion 15 c is received by the receiving member 20. Can be effectively prevented from leaving unexpectedly. In addition, since the overlapping portion 231 of the fixing portion 23 overlaps with the plate-like tip portion 15c, the plate-like tip portion 15c does not come into contact with the sliding door D2 or the wall portion W and be damaged in accordance with the opening / closing operation of the sliding door D2. Further, since the restraining protrusion 25 is formed so as to protrude from the overlapping portion 231 of the fixing portion 23 toward the facing portion 24, the restricting protrusion 25 can be easily configured, and the overlapping portion of the fixing portion 23 can also be configured. A gap between the 231 and the facing portion 24 (a space above the restraining protrusion 25) can be configured as a rotation-allowable space 201 of the plate-like tip portion 15c (see FIG. 12), and the space can be easily installed.

  In addition, the sliding door interlocking apparatus 1 demonstrated above is one Embodiment of the sliding door interlocking apparatus of this invention, About the specific structure etc., it can change suitably. Hereinafter, modifications of the present embodiment will be described.

  The receiving member 320 in the second embodiment includes a receiving body 321 that engages with the plate-like tip 15 c of the connecting member 15, and a fixed cover 322 that is attached to the receiving body 321.

  The receiving body 321 is different from the receiving body 21 of the above embodiment in that the facing portion 24 is omitted and the specific configuration of the fixing portion is changed. In addition, the protruding direction of the restraining protrusion is changed from the front-rear direction to the left-right direction. It differs greatly in that it is. Moreover, in the said embodiment, although the receiving main body 21 and the plate-shaped front-end | tip part 15c were comprised so that sliding door D1, D2 might be slid, the receiving main body 321 of this 2nd Embodiment is a board. It differs also in the point comprised so that it may be connected by inserting the receiving main body 321 from the upper direction of the shape front-end | tip part 15c.

  Specifically, the receiving body 321 is provided with a fixed portion 333 fixed to the adjacent sliding door D1 or the adjacent wall portion W via the fixed cover 322, and protrudes inward in the sliding door opening / closing direction at the lower end portion of the fixed portion 333. The restraining projection 335 is provided.

  Unlike the above-described embodiment, the fixing portion 333 is configured in a frontal portal shape. That is, the fixed portion 333 includes a horizontally long fixed main body portion 333a and a pair of fixed leg portions 333b that respectively hang downward from both left and right end portions of the fixed main body portion 333a, and between these fixed leg portions 333b. The plate-shaped tip portion 15c is arranged. The plate thickness of the fixed portion 333 is set corresponding to the thickness of the plate-like tip portion 15c. In the second embodiment, the plate thickness of the fixing portion 333 is set to be approximately equal to the thickness of the plate-like tip portion 15c.

  In addition, the fixed main body portion 333a has a pair of left and right first positioning projections 333c projecting forward to position with respect to the fixed cover 322, and the first positioning projections 333c forward. And a cover locking portion 333d projecting toward the head. The cover locking portion 333d is for detachably attaching the fixed cover 322, and includes a pair of upper and lower locking hook portions 333e as shown in FIG.
