[0021] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0022] In addition, in some of the figures, a part of the detailed reference numerals given to other figures is omitted.

[0023] Furthermore, in the following embodiments, directions such as the up and down directions are described based on the state after the door opening and closing device related to this embodiment is constructed.

[0024] Figures 1 to 5 It is a figure schematically showing an example of the door opening and closing device related to this embodiment.

[0025] The door opening and closing device 1 related to this embodiment is as Figure 1 and Figure 2 shown in (a) and (b) of, and includes an upper rail 10. The upper rail 10 guides the guiding members 15, 15 connected to the upper end portions 9a on both sides in the door width direction of the sliding door panel 9, and suspends and holds the sliding door panel 9 so as to be slidable in the door width direction. In addition, the door opening and closing device 1 includes a drive mechanism 20, and the drive mechanism 20 is connected to the first guiding member 15A on one side of the guiding members 15, 15, and slides the first guiding member 15A in the door width direction. If such a structure is made, then as long as the drive mechanism 20 is driven, the first guiding member 15A can be moved in the door width direction, and the sliding door panel 9 can be opened and closed (opened and locked). That is, the sliding door panel 9 can function as an automatic door. In addition, the door opening and closing device 1 includes an electronic lock 30 that can releasably inhibit the sliding door panel 9 in the locked position from moving to the open side. If such a structure is made, then if the electronic lock 30 is in the locked state, the sliding door panel 9 can be inhibited from moving to the open side, and if the electronic lock 30 is in the unlocked state, the sliding door panel 9 can be allowed to move to the open side.

[0026] In addition, as Figure 2As shown in (a), the door opening and closing device 1 includes an upper frame 3 as a fixing object to which the upper rail 10 is fixed. The door opening and closing device 1 may also be a sliding door device composed of a door frame 2 including the upper frame 3 and a sliding door panel 9. In addition, as the installation location of the door opening and closing device 1, it can be a general residence such as a single-family house or an apartment house. The door opening and closing device 1 can also be installed in public facilities such as hotel facilities, medical facilities, and welfare facilities, or commercial facilities such as offices, or various places such as various stores.

[0027] In the present embodiment, an example in which one sliding door panel 9 is constructed in a single-leaf pulling shape is shown. In the legend, an example in which the sliding door panel 9 is constructed in a sleeve wall storage shape is shown, but it can also be constructed in an appropriate storage form such as door box storage or exterior storage.

[0028] The door frame 2 is provided at an opening of a wall body provided in a building. The door frame 2 includes: an upper frame 3 (upper rail 10) that demarcates the upper side of the entrance / exit 8 that is opened and closed by the sliding door panel 9; a head-side vertical frame 5 that is arranged on the head side of the sliding door panel 9; a tail-side vertical frame 6 that is arranged on the tail side of the sliding door panel 9; and a mullion (intermediate vertical frame) 7. The mullion 7 is arranged along the entrance / exit 8-side end of the sleeve wall (not shown), and demarcates both sides in the opening width direction of the entrance / exit 8 together with the head-side vertical frame 5. In addition, the upper frame 3 can be provided on the ceiling in an attached or embedded manner, or can be provided along the lower end of the vertical wall. In addition, the lower side of the entrance / exit 8 can also be demarcated by a floor or an appropriate lower frame.

[0029] The upper frame 3 is long in the door width direction. The length dimension of the upper frame 3 is approximately twice the door width of the sliding door panel 9. In addition, as Figure 3 shown, the upper frame 3 is arranged with the thickness direction as the up-down direction. In addition, the depth dimension (dimension along the door thickness direction) of the sleeve wall side portion of the upper frame 3 arranged on the sleeve wall side is set to be smaller than the depth dimension of the entrance / exit 8 side portion arranged on the entrance / exit 8 side.

[0030] In addition, a receiving groove 4 is provided in the upper frame 3, and the upper side portion of a drive mechanism 20 described later is received in the receiving groove 4. If such a structure is made, the alignment of the upper rail 10 provided with the drive mechanism 20 can be easily performed. The receiving groove 4 opens downward and is provided so as to extend across the entire length of the upper frame 3. In addition, the upper frame 3 can be fixed to an appropriate upper frame base such as a lintel by fixing members such as screws or nails.

[0031] The header side vertical frame 5, the door tail side vertical frame 6, and the mullion 7 are elongated in the door height direction (vertical direction). The length dimensions of these header side vertical frame 5, door tail side vertical frame 6, and mullion 7 are made to be approximately the same as the dimension obtained by adding the door height dimension of the sliding door panel 9 to the dimension along the vertical direction of the upper rail 10 and the upper frame 3 including the drive mechanism 20. In addition, these header side vertical frame 5, door tail side vertical frame 6, and mullion 7 are arranged with the thickness direction as the door width direction. The depth dimension of the door tail side vertical frame 6 and the mullion 7 is set to be smaller than the depth dimension of the header side vertical frame 5.

[0032] It is also possible that the header side vertical frame 5 and the door tail side vertical frame 6 are fixed to an appropriate vertical frame base such as a column by fixing members. In addition, it is also possible that these header side vertical frame 5 and door tail side vertical frame 6 and the upper frame 3 are fixed to the vertical frame base and the upper frame base in a state of being assembled into a three-sided frame shape. In the illustrated example, an example is shown in which the facing depth surfaces of the upper end portions of these header side vertical frame 5 and door tail side vertical frame 6 are butted (abutted) against the respective end surfaces in the long side direction of the upper frame 3, and these header side vertical frame 5 and door tail side vertical frame 6 and the upper frame 3 are assembled into a vertical frame penetrating shape.

[0033] In addition, it is also possible to form a structure in which door insertion grooves for receiving the end portions (header side end portion and door tail side end portion) in the door width direction of the sliding door panel 9 are provided on the facing depth surfaces of these header side vertical frame 5 and door tail side vertical frame 6.

[0034] The upper end portion of the mullion 7 can also be fixed to the upper frame 3 and the lower end portion can be fixed to the floor. Additionally, it is also possible to form a structure in which a gap shielding member such as mohair that is in frictional contact with one surface in the thickness direction of the sliding door panel 9 is provided at the end portion of the mullion 7 on the side of the sliding door panel 9. In addition, as the door frame 2, it is not limited to the above structure, and various other structures are also possible.

[0035] The sliding door panel 9 is formed into a substantially rectangular flat plate shape that is long in one direction (the up-and-down direction). The door height dimension (length dimension) of the sliding door panel 9 only needs to be a dimension corresponding to the opening height of the doorway 8 opened and closed by the sliding door panel 9, and it can also be a standard door height dimension, for example, about 1800 mm to 2100 mm. In addition, the sliding door panel 9 can also form a high door with a door height dimension that is approximately the same height as the ceiling height, for example, about 2300 mm to 3000 mm. In addition, the door thickness dimension of the sliding door panel 9 can also be about 20 mm to 40 mm. In addition, the door width dimension of the sliding door panel 9 can also be, for example, about 500 mm to 1800 mm. When the sliding door panel 9 is installed indoors, it can be a relatively lightweight panel such as a so-called glossy panel, which is a structure in which a surface member is pasted on a panel core member including a frame-shaped core member formed of a general wood-based material or metal-based material used as an indoor sliding door. As the sliding door panel 9, it is not limited to such a glossy panel, and an appropriate structure can be made according to the installation location and the like.

[0036] At the upper end portion 9a on the header side on one side in the door width direction of the sliding door panel 9, the first guided member 15A that constitutes the guided member 15 is connected. At the upper end portion 9a on the door tail side on the other side in the door width direction, the second guided member 15B that constitutes the guided member 15 is connected. These first guided member 15A and second guided member 15B have substantially the same structure as each other. As Figure 3 shown, in these first guided member 15A and second guided member 15B, a mounted portion 16 to be mounted on the mounting portion of the sliding door panel 9 is provided. The mounting portion of the sliding door panel 9 is provided to open toward the outside and the upper side in the door width direction at each of the upper end portions 9a on both sides in the door width direction of the sliding door panel 9, and is formed into a recessed cup portion for the mounted portion 16 to be inserted.

[0037] In addition, these first guided member 15A and second guided member 15B include: a support shaft 16a provided so as to protrude upward from the mounted portion 16; and a guide body 17 fixed to the upper end portion of the support shaft 16a. In the guide body 17, a rotating body 18 that travels on a guide piece portion 13a of an upper rail 10 described later is provided. In the present embodiment, the rotating body 18 is provided to be rotatable about an axis along the door thickness direction. In addition, a structure is formed in which the rotating bodies 18, 18 are provided on both sides in the door thickness direction of the guide body 17 so as to be separated from each other in the door thickness direction. In addition, a structure is formed in which the rotating bodies 18, 18 on both sides in the door thickness direction are provided at intervals in the door width direction of the guide body 17 at multiple locations (two locations in the illustrated example) (refer to Figure 5 ).

[0038] In addition, a drive mechanism 20 is connected to the first guided member 15A on one side of the two sides in the door width direction, and details will be described later. That is, through the drive mechanism 20, the first guided member 15A slides in the door width direction, causing the second guided member 15B on the other side not connected to the drive mechanism 20 to slide in the door width direction in a driven manner.

[0039] In addition, as the first guided member 15A and the second guided member 15B, they are not limited to the above structure, and can also be made into an appropriate structure according to the upper rail 10 described later.

[0040] In addition, a guide groove or the like into which the lower end guide member such as a guide pin provided on the floor side is inserted can also be provided at the lower end portion of the sliding door panel 9.

[0041] As Figure 2 shown in (b) of the figure, the upper rail 10 is set to be approximately twice the length of the sliding door panel 9. A structure can be made in which the drive mechanism 20 is fixed to the first half on one side in the long side direction of the upper rail 10. The length of the upper rail 10 is set to a size smaller than twice the door width. The length of the upper rail 10 only needs to be set to an appropriate size according to the overlapping dimension of the end portion on the door tail side of the sliding door panel 9 in the locked state and the remaining pulled-out portion dimension of the sliding door panel 9 in the fully opened state, etc.

[0042] In addition, as Figure 3 shown, in the upper rail 10, a guide groove 11 for receiving the guided member 15 (the first guided member 15A and the second guided member 15B) is provided in a downward-opening manner. The guide groove 11 is provided so as to extend across the entire length of the upper rail 10. The guide body 17 of the guided member 15 is inserted into the guide groove 11 and is guided.

[0043] The upper rail 10 includes: a bottom plate-like portion 12 that delimits the bottom of the guide groove 11; side plate-like portions 13, 13 on both sides that delimit both sides in the groove width direction of the guide groove 11; and guide piece portions 13a, 13a that extend from the lower end portions of these side plate-like portions 13, 13 toward the facing direction.

[0044] At the front end portions in the extending direction of the guide piece portions 13a, 13a on both sides, ridges protruding upward are provided so as to extend across the entire length of the upper rail 10. The annular grooves provided on the outer peripheral surfaces of the rotating bodies 18, 18 of the guided member 15 are engaged with the ridges of these guide piece portions 13a, 13a, and the rotating bodies 18, 18 travel along the ridges of these guide piece portions 13a, 13a.

[0045] In addition, a fixing member 14 for fixing the upper rail 10 relative to the upper frame 3 is provided on the upper rail 10. In the illustrated example, a structure is adopted in which a plurality of fixing members 14 are provided at intervals in the longitudinal direction on the groove bottom plate-like portion 12 of the upper rail 10. In addition, it is configured to arrange these plurality of fixing members 14 in the free space where the components of the drive mechanism 20 provided on the upper rail 10 and the electronic lock 30 are not arranged. It is also possible that these fixing members 14 are caught and held by the catching portions provided on the upper frame 3. In addition, these fixing members 14 can be fixed to the upper frame 3 by fixing members such as threaded members.

[0046] As Figure 1 shown, the drive mechanism 20 is fixed to the above-mentioned upper rail 10. If such a structure is adopted, the upper rail 10 can be fixed relative to a fixing object such as the upper frame 3 of the door frame 2 on which the sliding door panel 9 is built in a state where the drive mechanism 20 is integrated with the upper rail 10.

[0047] In the present embodiment, the drive mechanism 20 includes a first driven rotary wheel 22 constituting a first rotary wheel and a second driven rotary wheel 24 constituting a second rotary wheel, and the first driven rotary wheel 22 and the second driven rotary wheel 24 are arranged at positions separated from each other in the door width direction (refer to Figure 2 ). In addition, the drive mechanism 20 includes: a rope-like transmission body 28 that is wound around each of the first driven rotary wheel 22 and the second driven rotary wheel 24 and is connected to the first guided member 15A; and a drive unit 25 that transmits drive to the rope-like transmission body 28. If such a structure is adopted, when the drive unit 25 is driven, the first guided member 15A connected to the rope-like transmission body 28 can be moved in the door width direction to open and close the sliding door panel 9.

[0048] The drive unit 25 includes: a drive rotary wheel 26 which is disposed between the first driven rotary wheel 22 and the second driven rotary wheel 24 and above the guide groove 11 of the upper rail 10, and transmits drive to the rope-shaped transmission body 28; and a motor 27 which rotates the drive rotary wheel 26. If such a structure is adopted, when the drive rotary wheel 26 is rotated by the motor 27, the first guided member 15A connected to the rope-shaped transmission body 28 can be moved in the door width direction to open and close the sliding door panel 9. In addition, compared with the structure in which the drive rotary wheel 26 and the motor 27 are disposed at one end portion in the door width direction, it is possible to achieve compactness in the dimension along the door width direction. Further, compared with the structure in which the drive rotary wheel 26 is disposed on one side in the door thickness direction of the upper rail 10, it is possible to achieve compactness in the dimension along the door thickness direction. Through these, it is also possible to provide a door frame 2 similar to that of a sliding door device provided in a normal building such as a house. In addition, for example, it is also possible to provide it for an already provided door frame 2, which is applicable not only at the time of new construction but also at the time of renovation or modification. Thus, it can be suitably used as a door opening / closing device 1 for opening and closing the following sliding door panel 9, which is provided in general houses such as single-family houses and apartment houses that have been built, public facilities such as hotel facilities, medical facilities, and welfare facilities, commercial facilities such as offices, and indoors of various stores. In addition, since the door opening / closing device 1 is compact, while the sliding door panel 9 can function as an automatic door, even when it is provided as an indoor sliding door, it is possible to reduce the sense of incongruity (noise) in appearance and it can be suitably used indoors.

[0049] The first driven wheel shaft and the second driven wheel shaft, which are the respective shafts of the first driven rotary wheel 22 and the second driven rotary wheel 24, are made parallel to each other. In addition, these first driven wheel shaft and second driven wheel shaft are disposed in a manner intersecting the axial direction of the drive wheel shaft of the drive rotary wheel 26, and the drive rotary wheel 26 is disposed with the axial direction being the door height direction.

[0050] On these first driven rotary wheel 22 and second driven rotary wheel 24, the rope-shaped transmission body 28 is wound in a parallel hanger shape. The first driven rotary wheel 22 and the second driven rotary wheel 24 have their first driven wheel shaft and second driven wheel shaft disposed in an inclined manner such that the lower displacement portion and the upper displacement portion of the rope-shaped transmission body 28 displaced in opposite sides in the door width direction are located at different positions in the door thickness direction of the upper rail 10 (see Figure 3 ). The first driven rotary wheel 22 and the second driven rotary wheel 24 have their first driven wheel shaft and second driven wheel shaft disposed in an inclined manner such that the lower displacement portion is located substantially at the center in the door thickness direction of the upper rail 10, and the upper displacement portion is located at a position biased to one side in the door thickness direction of the upper rail 10.

[0051] The first driven rotating wheels 22 and the second driven rotating wheels 24 are of the same size and shape as each other. In addition, the first driven rotating wheels 22 and the second driven rotating wheels 24 are thin disc-shaped with relatively small dimensions in the axial direction along the first driven wheel shaft and the second driven wheel shaft. In addition, the first driven rotating wheels 22 and the second driven rotating wheels 24 are made into pulleys having annular grooves on their respective outer peripheral surfaces for engaging a rope-shaped transmission body 28 which is a rope-shaped member. In addition, the first driven rotating wheels 22 and the second driven rotating wheels 24 are arranged in such a manner that they are in alignment with each other when viewed in the door width direction. The first driven wheel shafts and the second driven wheel shafts of the first driven rotating wheels 22 and the second driven rotating wheels 24 are arranged in a manner perpendicular to the long side direction of the upper rail 10 and are arranged in a manner inclined with respect to the horizontal plane (the upper surface of the groove bottom plate portion 12).

[0052] In addition, the first driven rotating wheels 22 and the second driven rotating wheels 24 are fixed to the upper rail 10 by fixing members 21 and 23. It can also be configured such that at least one of the first driven rotating wheels 22 and the second driven rotating wheels 24 is held on one or both of these fixing members 21 and 23 in a manner capable of adjusting the position in the door width direction.

[0053] In addition, as the first driven rotating wheels 22 and the second driven rotating wheels 24 and the fixing members 21 and 23 for fixing them to the upper rail 10, they are not limited to being configured as described above, and various other configurations can also be adopted.

[0054] In addition, as shown Figure 3 In the guiding bodies 17 and 17 of the first guided member 15A and the second guided member 15B, recesses are provided which open upward and to both sides in the door width direction. When viewed in the door width direction, the lower end side portions of the first driven rotating wheels 22 and the second driven rotating wheels 24 are received in the recesses. In addition, a connecting portion 17a for connecting the lower displacement portion of the rope-shaped transmission body 28 is provided in the guiding body 17 of the first guided member 15A. The connecting portion 17a is provided in such a manner as to be located within the recess of the guiding body 17.

[0055] The rope-shaped transmission body 28 is configured such that the upper displacement portion that is displaced on the upper surface side of the groove bottom circumferential surface of the annular grooves of the first driven rotating wheel 22 and the second driven rotating wheel 24 is in a position biased toward one side in the door thickness direction in the upper space above the guide groove 11. Further, the rope-shaped transmission body 28 is configured such that the lower displacement portion that is displaced on the lower surface side of the groove bottom circumferential surface of the annular grooves of the first driven rotating wheel 22 and the second driven rotating wheel 24 is located at the center in the groove width direction of the lower space inside the guide groove 11. The rope-shaped transmission body 28 may be one in which a connecting portion 17a to which the first guided member 15A is fixed is provided on a part formed in a ring shape, or may be one formed in a substantially ring shape by connecting both end portions in the long side direction to both sides in the door width direction at the connecting portion 17a. Further, the rope-shaped transmission body 28 may have a structure that is not easily stretched, and for example, it may be a metal wire, a twisted rope formed by twisting appropriate fibers, or a wire rope obtained by combining fibers, etc.

[0056] The drive rotating wheel 26 is formed into a thin disk shape with a small dimension in the axial direction of the drive wheel shaft. Further, the drive rotating wheel 26 is formed into a pulley having an annular groove on the outer circumferential surface for engaging the rope-shaped transmission body 28. The upper displacement portion of the rope-shaped transmission body 28 is wound around the drive rotating wheel 26 approximately once.

[0057] A gear (rotating wheel side gear) for transmitting rotation to a gear (motor side gear) provided on a motor 27 that rotates the drive rotating wheel 26 is provided on the drive rotating wheel 26. Further, it may be configured such that the motor 27 is arranged on one side in the door width direction of the drive rotating wheel 26 with the axial direction of the output shaft being the door width direction, and the drive wheel shaft of the drive rotating wheel 26 and the output shaft of the motor 27 are arranged to intersect each other. In addition, as the rotating wheel side gear and the motor side gear, an appropriate structure may be formed according to the arrangement form of the drive rotating wheel 26 and the motor 27. Further, as these rotating wheel side gears and motor side gears, it is not limited to a structure of direct meshing, and may also be a structure in which rotation is transmitted via an appropriate intermediate gear or the like.

[0058] Further, these drive rotating wheel 26 and motor 27 may also be fixed to the upper rail 10 by appropriate fixing members.

[0059] Further, as the motor 27, it may be a servo motor or the like that can rotate forward and backward and can control the rotational speed.

[0060] Further, in the above example, an example in which the drive wheel shaft of the drive rotating wheel 26 is set in the door height direction is shown, but it may also be a structure in which it is set in the door thickness direction.

[0061] Further, in the present embodiment, as Figure 1As shown, a structure is formed in which a control block 29 for controlling the rotation of the motor 27 is provided on one side in the door width direction of the motor 27. The control block 29 is provided with a power supply unit for supplying a driving power source to the motor 27, and a control circuit and the like connected to the motor 27 via appropriate signal lines and the like. The control block 29 controls the motor 27 to rotate forward or backward, and moves the sliding door panel 9 to the fully open position or the locked position. In the illustrated example, an example is shown in which the control block 29 is formed in a substantially rectangular columnar shape that is long in the door width direction.

[0062] As Figure 5 shown, the electronic lock 30 includes a latch portion 40 that extends substantially in the door width direction from a base end portion 41, and the base end portion 41 is rotatably held about an axis (lock axis) 42 along the door thickness direction. The latch portion 40 is configured such that a front end portion 43 that engages with a latch receiving portion 19 of the first guided member 15A, which is at least one of the first guided member 15A and the second guided member 15B among the first guided member 15A and the second guided member 15B, moves up and down between an upper release position and a lower locked position. If such a structure is formed, compared with a structure in which, for example, the rotation of a pulley or the like constituting the drive mechanism 20 is suppressed for locking, damage to the drive mechanism 20 and the like can be suppressed. In addition, for example, compared with a structure in which a lock shaft rod that is moved up and down in the axial direction is provided, damage to the latch portion 40 and the like can be suppressed. That is, it is possible to withstand the load acting on the latch portion 40 at the locked position when the sliding door panel 9 is manually moved to the open side in the substantially long side direction of the latch portion 40.

[0063] In the present embodiment, the electronic lock 30 is fixed to the upper rail 10 such that it is located above the center side in the door width direction of the first guided member 15A, which is one of the guided members, when the sliding door panel 9 is in the locked position. If such a structure is formed, compared with a structure that requires a space to be provided above the outer side in the door width direction of the first guided member 15A, which is one of the guided members of the sliding door panel 9, at the locked position, it is possible to achieve a reduction in size along the door width direction. In addition, since the electronic lock 30 is integrally fixed to the upper rail 10, compared with a structure that requires the electronic lock to be provided separately from the upper rail 10, the workability can be improved. In addition, the electronic lock 30 is located above the entrance 8, and compared with a structure provided on the sleeve wall side or the sliding door side (pocket side), the maintainability and the operability during manual unlocking can be improved.

[0064] In addition, the electronic lock 30 is provided so as to be located between the first driven rotating wheel 22 and the second driven rotating wheel 24. If such a structure is formed, it is possible to use the free space between the first driven rotating wheel 22 and the second driven rotating wheel 24 that constitute the drive mechanism 20 to provide the electronic lock 30, and it is possible to achieve a reduction in size along the vertical direction of the upper rail 10.

[0065] In addition, the electronic lock 30 is arranged such that when the sliding door panel 9 is in the locked position, the electronic lock 30 is located above the central side in the door width direction of the first guided member 15A on the door head side of the guided member as one side, so as to be able to suppress the movement of the first guided member 15A on the door head side of the guided member as one side toward the open side. For example, when the electronic lock 30 is arranged adjacent to the second guided member 15B of the sliding door panel 9 in the locked position, it is necessary to change the installation position of the electronic lock 30, etc. when the door width dimension of the sliding door panel 9 is different, but there is no such need. That is, even when the door width dimension of the sliding door panel 9 is different, it is possible to make corresponding arrangements without changing the installation position of the electronic lock 30 relative to the upper rail 10.

[0066] In addition, the electronic lock 30 is arranged such that when the sliding door panel 9 is in the locked position, the electronic lock 30 is located on the front side in the moving direction of the first guided member 15A of the guided member as one side moving toward the open direction. If such a structure is adopted, compared with the structure in which the electronic lock 30 is arranged on the front side in the moving direction of the first guided member 15A of the guided member as one side of the sliding door panel 9 in the locked position moving toward the locked direction, it is possible to simplify the structures of the latch portion 40 and the latch receiving portion 19. That is, it is not necessary to provide a hooked engaging portion that is engaged with the engaged portion on the latch receiving portion 19 and a hooking portion that is hooked on the engaged portion on the latch portion 40, and the latch receiving portion 19 can be used as an abutting portion for the front end portion 43 of the latch portion 40 to abut against.

[0067] That is, in the present embodiment, the electronic lock 30 is arranged such that when the sliding door panel 9 is in the locked position, the electronic lock 30 is located on the front side in the moving direction of the first guided member 15A on the door head side moving toward the open direction as the central side in the door width direction.

[0068] Specifically, the electronic lock 30 includes a first housing portion 31 and a second housing portion 32 that are divided in the door thickness direction. The first housing portion 31 and the second housing portion 32 constitute a lock housing that rotatably holds the latch portion 40 around the latch shaft 42, and the lock housing is fixed to the upper rail 10. In addition, the electronic lock 30 includes: a motor 33 that constitutes a latch driving portion for moving the front end portion 43 of the latch portion 40 up and down; and locking / unlocking detection portions 36 and 37 that detect the locked state and the unlocked state of the electronic lock 30.

[0069] The first housing part 31 and the second housing part 32 are configured to be open toward the lower side in the assembled state. In the illustrated example, the first housing part 31 on one side in the door thickness direction is shown in a shape that is open toward the other side and the lower side in the door thickness direction, and the second housing part 32 on the other side in the door thickness direction is shown as a plate shape configured to cover the opening on the other side in the door thickness direction of the first housing part 31.

[0070] These first housing part 31 and second housing part 32 are fixed to the upper rail 10 by fixing members such as threaded members. In the illustrated example, an opening for receiving the electronic lock 30 is provided in a notch shape on the groove bottom plate-shaped part 12 and the side plate-shaped part 13 on one side in the door thickness direction of the upper rail 10, and an example of fixing the fixed part provided on the first housing part 31 to the side plate-shaped part 13 on one side in the door thickness direction is shown (also refer to Figure 1 ).

[0071] The latch part 40 is configured such that the base end part 41 on one side in the long side direction is located on the center side (door tail side) in the door width direction of the sliding door panel 9 where the front end part 43 on the other side in the long side direction is closer to the locking position. In the present embodiment, as shown in (a) of Figure 5 , this latch part 40 is configured to be inclined such that it descends as it moves toward the front end side in the locked position. Further, as shown in (b) of Figure 5 , the latch part 40 is configured such that the base end part 41 and the front end part 43 are arranged at substantially the same height, that is, the long side direction is substantially the door width direction, in the unlocked position.

[0072] The latch shaft 42 of the base end part 41 of the latch part 40 is arranged with the axial direction being the door thickness direction. It is possible that the latch shaft 42 is fixedly provided to the latch part 40 and is rotatably held with respect to the bearing parts provided on the first housing part 31 and the second housing part 32. Alternatively, it is also possible to have a structure in which a bearing part is provided on the latch part 40 side, and this bearing part rotatably holds the latch shaft 42 fixedly provided on the first housing part 31 and the second housing part 32 side.

[0073] At the front end portion 43 of the latch portion 40, a connecting member 38 is connected. The connecting member 38 is connected to a rotating body 35 rotated by a motor 33, and the front end portion 43 moves up and down as the rotating body 35 rotates. The rotating body 35 is disposed above the front end side of the latch portion 40. The rotating body 35 is rotatably held on the first housing portion 31 and the second housing portion 32 about a rotation axis 35a disposed in the door thickness direction in the axial direction. In the illustrated example, the rotating body 35 is a worm gear meshing with a worm 34 provided on the output shaft of the motor 33. In addition, as a form in which the motor 33 rotates the rotating body 35, it is not limited to such a form formed by a worm pair, and other gears may be provided, or the rotating body 35 may be directly provided on the output shaft of the motor 33, etc.

[0074] The connecting member 38 is elongated in the vertical direction. The upper end portion, which is one end portion in the long side direction of the connecting member 38, is rotatably connected to a radial side of the rotation axis 35a that is eccentric with respect to the rotation axis 35a of the rotating body 35, and the lower end portion, which is the other end portion in the long side direction, is rotatably connected to the front end portion 43 of the latch portion 40. In the connecting member 38, an insertion through hole 38a for inserting an upper end connecting shaft 35b is provided along the door thickness direction, and the upper end connecting shaft 35b is rotatably inserted and held in the shaft insertion through hole provided in the rotating body 35. In addition, at the lower end portion of the connecting member 38, a lower end connecting shaft 38b is provided, and the lower end connecting shaft 38b is rotatably inserted and held in the insertion through hole along the door thickness direction provided in the front end portion 43 of the latch portion 40 (also refer to Figure 4 in (b)).

[0075] If the motor 33 is driven, the rotating body 35 rotates about the rotation axis 35a by the worm 34, and the upper end connecting shaft 35b rotates around the rotation axis 3a. Accordingly, while the upper end side swings in the substantially door width direction, the connecting member 38 moves up and down. Thereby, the front end portion 43 of the latch portion 40 moves up and down. That is, as shown in Figure 5 (a), if the upper end connecting shaft 35b is located below the rotation axis 35a of the rotating body 35, the connecting member 38 and the front end portion 43 of the latch portion 40 are in the lower limit position, and the latch portion 40 is in the locked position. In this state, the front end portion 43 of the latch portion 40 is disposed to face the latch receiving portion 19 of the first guiding member 15A of the sliding door panel 9 in the locking position, and the movement of the first guiding member 15A toward the open side is suppressed. In addition, as shown in Figure 5As shown in Fig. (b), if the upper end connecting shaft 35b is located above the rotation axis 35a of the rotating body 35, the front end portions 43 of the connecting member 38 and the latch portion 40 are in the upper limit position, and the latch portion 40 is in the released position. In this state, the latch portion 40 is in a position where it does not interfere with the first guiding member 15A of the sliding door panel 9 in the locked position, and the first guiding member 15A can be moved toward the open side. In addition, the mechanism for moving the front end portion 43 of the latch portion 40 up and down is not limited to the structure shown in the figure, and various other structures are also possible.

[0076] As Figure 3 shown, the latch receiving portion 19 engaged by the front end portion 43 of the latch portion 40 is provided between the rotating bodies 18, 18 located on both sides in the door thickness direction when viewed in the door width direction. If such a structure is adopted, compared with the structure in which the rotating body 18 is used as the latch receiving portion 19, damage to the rotating body 18 can be suppressed. In addition, compared with the structure in which the latch receiving portion 19 is provided on the other side in the door thickness direction of the first guiding member 15A having the rotating body 18 provided only on one side in the door thickness direction, the front end portion 43 of the latch portion 40 can be stably engaged.

[0077] In addition, in the present embodiment, as Figure 5 shown in Fig. (a), the latch receiving portion 19 is in the shape of an inclined surface orthogonal to the long side direction of the latch portion 40 in the locked position. If such a structure is adopted, when the sliding door panel 9 is to be manually moved toward the open side, the load acting on the latch portion 40 in the locked position can be effectively received along the long side direction of the latch portion 40. In addition, interference between the front end portion 43 of the latch portion 40 and the latch receiving portion 19 when the latch portion 40 is displaced to the released position can be suppressed.

[0078] The latch receiving portion 19 is provided at the end portion on the door trailing side of the guiding main body 17 of the first guiding member 15A. The latch receiving portion 19 may be integrally provided with the guiding main body 17, or may be a structure in which other components are fixedly provided. In addition, the latch receiving portion 19 is provided so as not to interfere with the rope-like transmission body 28 connected to the first guiding member 15A.

[0079] The latch receiving portion 19 has a surface facing the door tail side that abuts or is close to and opposed to the front end portion 43 of the latch portion 40 and is inclined obliquely upward in a manner that decreases as it faces the lower side. The front end surface of the front end portion 43 of the latch portion 40 is inclined obliquely downward in a shape substantially parallel to the latch receiving portion 19 and is disposed opposite to the latch receiving portion 19 at the locked position. In the illustrated example, an example is shown in which the front end surface of the front end portion 43 is formed in an arc shape when viewed in the door thickness direction. The front end portion 43 of the latch portion 40 only needs to be formed in an appropriate shape so as to be disposed opposite to the latch receiving portion 19 of the first guided member 15A at the locked position and be able to suppress the first guided member 15A from moving to the open side.

[0080] In addition, the inclination angle of the latch receiving portion 19 is set to an appropriate angle corresponding to the inclination angle of the latch portion 40 so as to be orthogonal to the long side direction of the latch portion 40 at the locked position.

[0081] Also, from the viewpoint of suppressing interference with the latch receiving portion 19 at the release position, reducing the load acting on the latch portion 40 at the locked position, etc., the inclination angle of the latch portion 40 at the locked position can be set to an appropriate angle. The inclination angle of the latch portion 40 at the locked position relative to the horizontal plane can be about 5 degrees to 30 degrees. In the illustrated example, an example is shown in which it is set to about 20 degrees. That is, as the latch portion 40 that extends substantially in the door width direction, it also includes a structure that is inclined at about 30 degrees relative to the horizontal plane. In addition, in the illustrated example, an example is shown in which the inclination angle of the latch receiving portion 19 relative to the horizontal plane is set to about 70 degrees corresponding to the inclination angle of the latch portion 40 at the locked position. In addition, the long side direction of the latch portion 40 at the locked position is orthogonal to the latch receiving portion 19, and in addition to including the case where the angle formed by the long side direction of the latch portion 40 at the locked position and the latch receiving portion 19 is 90 degrees when viewed in the door thickness direction, it can also include about 85 degrees to 95 degrees.

[0082] In addition, in the present embodiment, a structure is formed that can manually operate the latch portion 40 in the locked position to the release side. If such a structure is formed, then in the case where the motor 33 does not operate due to a power outage or a failure, etc., the latch portion 40 in the locked position can also be displaced to the release position by manual operation. In addition, for example, when closing the sliding door panel 9 located on the open side, even when the latch portion 40 is in the locked position, the latch portion 40 can be pushed up by the guide body 17 of the first guided member 15A to move to the release side, thereby closing the sliding door panel 9.

[0083] In the illustration, an example of a structure is shown where the insertion through-hole 38a of the connecting member 38 is formed as an elongated hole that is long in the longitudinal direction (vertical direction) of the connecting member 38, allowing the front end portion 43 of the latch portion 40 in the locked position to move upward. That is, a structure is formed such that the connecting member 38 and the front end portion 43 of the latch portion 40 can be moved upward along the insertion through-hole 38a with respect to the upper end connecting shaft 35b of the rotating body 35 in the locked position.

[0084] In addition, an example is shown where an operation recess 44 as a manual operation portion is provided at the front end portion 43 of the latch portion 40. The operation recess 44 can be provided by penetrating the front end portion 43 of the latch portion 40 in the door thickness direction. In addition, the operation recess 44 can be a structure that is operated by inserting a tool such as a screwdriver. In addition, as Figure 1 shown, a notch portion is formed in the side plate-shaped portion 13 of the upper rail 10 to expose the front end portion 43 of the latch portion 40 so that the operation recess 44 can be operated. Alternatively, a structure can be formed where notch portions for exposing the front end portion 43 of the latch portion 40 are provided on the side plate-shaped portions 13, 13 on both sides in the door thickness direction of the upper rail 10 so that the manual release operation of the latch portion 40 can be performed from both sides in the door thickness direction. In addition, as the manual operation portion, it is not limited to the operation recess 44 as in the illustration, and various other structures can be formed. In addition, a structure can be formed where an appropriate holding mechanism for holding the latch portion 40 set to the release position by manual operation is provided.

[0085] In addition, in the present embodiment, a structure is formed where a biasing member 39 for biasing the latch portion 40 toward the locked position side is provided. If such a structure is formed, the latch portion 40 set to the release position by manual operation can be returned to the locked position. In the illustration, the biasing member 39 is formed as a helical coil spring (torsion spring) with the latch shaft 42 inserted through the coil portion. One arm end portion 39a of the biasing member 39 is abutted against the restricting wall portion 31a provided on the first housing portion 31, and the other arm end portion 39b of the biasing member 39 is abutted against the upper side surface of the latch portion 40. With such a structure, the biasing member 39 is a structure that biases the front end portion 43 of the latch portion 40 downward. In addition, as the biasing member 39, it is not limited to a helical coil spring, and other spring members such as a leaf spring, a compression coil spring, and a tension coil spring can also be used. In addition, it is not limited to spring members, and rubber members, etc. can also be used. In addition, as the form capable of manually operating the latch portion 40 toward the release side, it is not limited to the above form, and various other structural forms can also be used.

[0086] In the present embodiment, the locking / unlocking detection units 36 and 37 are configured such that a locking detection unit 36 for detecting the locked state and an unlocking detection unit 37 for detecting the unlocked state are provided separately (see Figure 4 (b) in the figure). In addition, an example of a microswitch having buttons (actuator units) 36a and 37a is shown. The buttons (actuator units) 36a and 37a are pushed down by the push portions 35c and 35d provided on the rotating body 35, thereby pushing down these locking detection unit 36 and unlocking detection unit 37. In the illustrated example, an example is shown in which levers 36b and 37b for pushing down the buttons 36a and 37a are provided on these locking detection unit 36 and unlocking detection unit 37.

[0087] These locking detection unit 36 and unlocking detection unit 37 are provided at intervals in the door thickness direction so as to be in positions that coincide with each other when viewed in the door thickness direction. In the illustrated example, an example is shown in which these locking detection unit 36 and unlocking detection unit 37 are provided on one side in the door width direction of the rotating body 35 between the motor 33 and the latch portion 40. Alternatively, these locking detection unit 36 and unlocking detection unit 37 may be held in such a manner that they are sandwiched between the first housing portion 31 and the second housing portion 32 on both sides in the door thickness direction via appropriate fixing members.

[0088] The locking detection unit 36 is provided on one side in the door thickness direction of the rotating body 35. As Figure 4 shown in (a) in the figure, on one side in the door thickness direction of the rotating body 35, the push portion 35c that pushes down the button 36a via the lever 36b of the locking detection unit 36 is provided so as to protrude toward the one side in the door thickness direction. As Figure 5 shown in (a) in the figure, the push portion 35c is provided so as to push down the button 36a of the locking detection unit 36 when the latch portion 40 is in the locked position. That is, the push portion 35c is provided at a position where it pushes down the button 36a of the locking detection unit 36 when the upper end connecting shaft 35b of the rotating body 35 is located below the rotation shaft 35a.

[0089] The unlocking detection unit 37 is provided on the other side in the door thickness direction of the rotating body 35. On the other side in the door thickness direction of the rotating body 35, the push portion 35d that pushes down the button 37a via the lever 37b of the unlocking detection unit 37 is provided so as to protrude toward the other side in the door thickness direction. As Figure 5 shown in (b) in the figure, the push portion 35d is provided so as to push down the button 37a of the unlocking detection unit 37 when the latch portion 40 is in the unlocked position. That is, the push portion 35d is provided at a position where it pushes down the button 37a of the unlocking detection unit 37 when the upper end connecting shaft 35b of the rotating body 35 is located above the rotation shaft 35a.

[0090] The push-down portions 35d that push down the button 37a of the unlocking detection unit 37 and the push-down portions 35c that push down the button 36a of the locking detection unit 36 are arranged to be opposed to each other with the rotation axis 35a of the rotating body 35 interposed therebetween when viewed in the door thickness direction. Further, these push-down portions 35c, 35d are arranged to extend in the circumferential direction with an interval therebetween in the circumferential direction. The circumferential dimension of these push-down portions 35c, 35d may be set to an appropriate dimension so as to be able to detect the locked state and the unlocked state. In the illustrated example, an example is shown in which the circumferential dimension of the push-down portion 35d that pushes down the button 37a of the unlocking detection unit 37 is larger than the circumferential dimension of the push-down portion 35c that pushes down the button 36a of the locking detection unit 36.

[0091] Further, these locking detection unit 36 and unlocking detection unit 37 and the motor 33 may be connected to the above-described control block 29 via signal lines or the like. Further, this electronic lock 30 may also be configured to be locked and unlocked by a control signal (locking signal and unlocking signal) from the control block 29 or a wireless signal (locking signal and unlocking signal) from a remote location or the like. In addition, as the locking and unlocking detection units 36, 37, it is not limited to the micro switch as described above, and it may also be configured to detect the rotation angle of the rotating body 35 to detect locking and unlocking, or various other configurations.

[0092] Further, it may also be as Figure 3 shown, the door opening and closing device 1 includes covers 45, 45 disposed on both sides in the door thickness direction of the upper rail 10 so as to cover between the upper frame 3 and the upper rail 10. These covers 45, 45 may be fixed to the upper rail 10 by an appropriate adhesive or fixing member or the like, or may also be configured to have a locking portion that locks with a locked portion provided on the upper rail 10. Further, in the case of being configured as the sleeve wall storage as described above, the cover 45 on the sleeve wall side may also be provided to cover from the vertical frame 5 on the door head side to the mullion 7.

[0093] Further, it may also be configured to have a position detection unit that detects the position of the sliding door panel 9 or a detection unit that detects a detection object such as a human body or the like provided at an appropriate position of the door opening and closing device 1.

[0094] Further, in the above example, an example is shown in which the electronic lock 30 that inhibits the first guided member 15A on the door head side from moving to the open side is provided, but it may also be configured to have an electronic lock 30 that inhibits the second guided member 15B on the door tail side from moving to the open side instead of or in addition to that.

[0095] In addition, in the above example, an example is shown in which the moving direction front side of the guided member 15 (first guided member 15A) of the sliding door panel 9 with the electronic lock 30 set at the locked position moves in the opening direction. However, it is not limited to such a form.

[0096] In addition, in the above example, an example is shown in which the latch receiving portion 19 of the guided member 15 (first guided member 15A) is provided between the rotators 18, 18 on both sides in the door thickness direction when viewed in the door width direction. However, it is not limited to such a form. For example, the latch receiving portion 19 can also be made as one of the rotators 18, or a structure in which the latch receiving portion 19 is provided on the guide body 17 of the guided member 15 (first guided member 15A) having a rotator 18 provided only on one side in the door thickness direction.

[0097] In addition, in the above example, an example is shown in which the drive rotating wheel 26, the first driven rotating wheel 22, and the second driven rotating wheel 24 of the drive mechanism 20 are made into pulleys. However, they can also be made into gears (sprockets), etc. In addition, the rope-like transmission body 28 is not limited to being made into a rope-like member that matches the drive rotating wheel 26, the first driven rotating wheel 22, and the second driven rotating wheel 24, and can also be a belt, a ball chain, a chain, etc. In addition, in the above example, an example is shown in which the drive rotating wheel 26 and the motor 27 are provided between the first driven rotating wheel 22 and the second driven rotating wheel 24. However, it is not limited to such a form. One of the first driven rotating wheel 22 and the second driven rotating wheel 24 can also be made into the drive rotating wheel that constitutes the first rotating wheel around which the rope-like transmission body 28 is wound, and the other can be made into the driven rotating wheel that constitutes the second rotating wheel. In this case, a structure can also be made in which an appropriate motor is provided so as to be able to transmit the rotation to the drive rotating wheel. In addition, as the drive mechanism 20, it is not limited to such a structure having the rope-like transmission body 28 displaced by the drive rotating wheel. For example, it can also be a structure in which a connecting portion displaced in the door width direction by a screw rotated by a motor is connected to the first guided member 15A. As the drive mechanism 20, various other structures are also possible. The above-described structures of the respective devices, components, and parts of the door opening / closing device 1 of the present embodiment are merely examples, and various other modifications are also possible.
