Mode for Carrying Out the Invention

[0008] (First Embodiment) Hereinafter, an electric lock-equipped fitting system according to the first embodiment will be described based on the drawings. The following embodiments show one aspect of the present disclosure, do not limit the present disclosure, and can be arbitrarily changed within the scope of the technical idea of the present disclosure. In the following description, the direction along the horizontal direction connecting the outdoor side and the indoor side is referred to as the indoor-outdoor direction. The direction along the horizontal direction orthogonal to the indoor-outdoor direction is referred to as the width direction. The direction orthogonal to the indoor-outdoor direction and the width direction is referred to as the vertical direction. In each component, the side away from the center in the indoor-outdoor direction and the width direction may be referred to as the outer side, and the side toward the center may be referred to as the inner side.

[0009] As shown in FIGS. 1 and 2, the electric lock-equipped fitting system 100 includes a frame body 10, two shojis 16, 16, an electric lock 110, an opening / closing device 7, a transmitting unit 8, and a control device 9.

[0010] The frame body 10 is formed in a rectangular frame shape. The two shojis 16, 16 are movable in the width direction inside the frame body 10.

[0011] The electric lock 110 locks and unlocks the two sliding doors 16, 16. When the sliding doors 16, 16 are in the closed position, closing the inside of the frame 10, the widthwise ends of the sliding doors 16, 16 are arranged to overlap in the indoor-outdoor direction. The electric lock 110 is attached to the end of the sliding door 16 located on the indoor side (see Figure 20). As shown in Figure 3, the electric lock 110 includes a lock housing 111, a lock cover 112, a lock 1, a drive unit 113, and a battery 115. The drive unit 113 is a power source that rotates the lock 1, and is, for example, a motor. The drive unit 113 receives power from the battery 115. The electric lock 110 is attached to the vertical frame 16a of one of the sliding doors 16 (see Figure 20). Between the lock housing 111 and the lock cover 112, the lock 1, the drive unit 113, the battery 115, and the control device 9 (described later) are housed.

[0012] Figures 4 to 6 show the lock 1 with the knob 20 (see Figure 3) and other parts removed. A receiving member 14 is attached to the vertical frame 16b of the other sliding door 16. The lock 1 restrains the opening and closing of the sliding door 16 by hooking onto the receiving member 14. With the lock 1 hooked onto the receiving member 14 as shown in Figure 5, it is possible to pull the vertical frame 16a and the vertical frame 16b of one sliding door 16 together, as shown in Figure 6.

[0013] The lock 1 comprises a fixed part 2, a rotating shaft part 3, a hook part 4, a rotating part 5, and a rotational force transmission part 6. The fixed part 2 is fixed to a base 15 provided at the bottom of the lock housing 111. The rotating shaft part 3 is attached to the fixed part 2. The hook part 4 is movably supported on the fixed part 2 and can be hooked onto a receiving member 14. The rotating part 5 is rotatably supported on the rotating shaft part 3 attached to the fixed part 2 so as to rotate around a rotation axis 31. The rotational force transmission part 6 receives the rotational force of the rotating part 5 around the rotation axis 31 and transmits the rotational force to the hook part 4. The rotational force transmission part 6 is a pin. As shown in Figure 7, the rotating part 5 rotates by the power of the drive unit 113. A rack part 55 is provided on the outer circumference of the rotating part 5, which converts the rotation of the drive unit 113 into rotation around the rotation axis 31.

[0014] As shown in Figures 8 and 9, the fixing part 2, the hook part 4, and the rotating part 5 are arranged in this order, overlapping each other. The direction in which the fixing part 2, the hook part 4, and the rotating part 5 overlap is referred to as the thickness direction. The axes of the rotating shaft part 3 and the rotational force transmission part 6 each extend in the thickness direction. The thickness direction is sometimes referred to as the axial direction. The direction in which the vertical frames 16a and 16b of the sliding door 16 face each other when closed is referred to as the horizontal direction. The horizontal direction and the thickness direction are perpendicular. The direction perpendicular to both the horizontal and thickness directions is referred to as the vertical direction. When the sliding door 16 closes the opening, the receiving member 14 attached to the vertical frame 16b shown in Figures 4 to 6 and the lock 1 face each other in the horizontal direction. The direction around the rotation axis 31 of the rotating shaft part 3 is sometimes referred to as the rotation direction. In the drawings, the thickness direction is indicated by arrow Z, the vertical direction by arrow Y, the horizontal direction by arrow X, and the rotation direction by arrow A.

[0015] As shown in Figures 8 to 10, the fixing part 2 is flat. The fixing part 2 is positioned facing the thickness direction Z. The outer shape of the fixing part 2 is circular with two notches 21 formed on its outer circumference. A fixing hole 22 is formed in the center of the fixing part 2, penetrating the plate surface in the thickness direction Z. The rotating shaft part 3 is inserted through the fixing hole 22. The fixing part 2 is provided with a first guide groove 23 and a second guide groove 24 that guide the movement of the hook part 4. The first guide groove 23 and the second guide groove 24 penetrate the fixing part 2 in the thickness direction Z.

[0016] As shown in Figure 10, the first guide groove 23 has a first circular arc portion 231 with a central angle of 90° centered at the center of the fixing portion 2, and a first straight portion 232 extending radially from one end of the first circular arc portion 231 toward the outer circumference of the fixing portion 2. The portion of the first circular arc portion 231 in the first guide groove 23 that connects to the first straight portion 232 is denoted as the switching position 23c. The end of the first circular arc portion 231 opposite to the switching position 23c is denoted as the first end portion 23a. The end of the first straight portion 232 opposite to the switching position 23c is denoted as the second end portion 23b.

[0017] The second guide groove 24 has a second arc portion 241 that is arc-shaped with a central angle of 90° centered at the center of the fixing portion 2, and a second straight portion 242 that extends radially toward the center of the fixing portion 2 from one end of the second arc portion 241. The portion of the second guide groove 24 where the second arc portion 241 connects with the second straight portion 242 is denoted as the switching position 24c. The end of the second arc portion 241 opposite to the switching position 24c is denoted as the first end portion 24a. The end of the second straight portion 242 opposite to the switching position 24c is denoted as the second end portion 24b.

[0018] The first end 23a of the first guide groove 23 and the first end 24a of the second guide groove 24 are arranged on the same straight line extending in the vertical direction Y through the center of the fixing part 2. The first straight section 232 and the second straight section 242 are arranged on the same straight line extending in the horizontal direction X through the center of the fixing part 2. The switching position 23c and the second end 23b of the first guide groove 23, and the switching position 24c and the second end 24b of the second guide groove 24 are arranged on the same straight line extending in the horizontal direction X through the center of the fixing part 2. The rotational force transmission section 6 is inserted into the first guide groove 23. The guided section 43 of the hook section 4 is inserted into the second guide groove 24.

[0019] As shown in Figures 7, 8, 11, and 12, the hook portion 4 has a flat hook plate portion 41, a hook portion 42 that protrudes from the hook plate portion 41 and hooks onto the receiving member 14 (see Figures 4 to 6), and a guided portion 43 that protrudes from the hook plate portion 41 and is introduced into the second guide groove portion 24. The hook portion 4 is positioned so that the hook plate portion 41 faces in the thickness direction Z. The hook portion 42 protrudes from a part of the outer edge of the hook plate portion 41 on one side in the thickness direction Z, on the side that overlaps with the rotating portion 5. The guided portion 43 protrudes from the hook portion 4 on the other side in the thickness direction Z, on the side that overlaps with the fixing portion 2. The guided portion 43 is inserted into the second guide groove portion 24.

[0020] As shown in Figures 9 and 12, the hook plate portion 41 has an elongated hole portion 44 in its center. The rotating shaft portion 3 is inserted into the elongated hole portion 44. The direction in which the elongated hole portion 44 extends is referred to as the length direction, and the direction perpendicular to the length direction is referred to as the width direction. The length dimension of the elongated hole portion 44 is larger than the diameter of the rotating shaft portion 3. The width dimension of the elongated hole portion 44 is approximately the same as the diameter of the rotating shaft portion 3. The rotating shaft portion 3 inserted into the elongated hole portion 44 can move in the length direction of the elongated hole portion 44.

[0021] A hook hole 45 is formed in the hook plate portion 41 at a position away from the outer edge side of one end of the elongated hole portion 44 in the longitudinal direction. The rotational force transmission portion 6 is inserted into the hook hole portion 45. The diameter of the hook hole portion 45 is approximately the same as the diameter of the rotational force transmission portion 6. The guided portion 43 is positioned at a position away from the outer edge side of the other end of the elongated hole portion 44 in the longitudinal direction. The elongated hole portion 44, the hook hole portion 45, and the guided portion 43 are arranged on the same straight line that passes through the center of the elongated hole portion 44 and extends in the longitudinal direction of the elongated hole portion 44. The elongated hole portion 44 is positioned between the hook hole portion 45 and the guide portion. The end of the elongated hole portion 44 on the hook hole portion 45 side is denoted as the first end portion 44a, and the end on the guided portion portion 43 side is denoted as the second end portion 44b.

[0022] As shown in Figures 8, 9, and 13, the rotating part 5 is a flat plate-shaped member. The surface of the rotating part 5 is shaped like a circle with a portion removed that does not include the center. The rotating part 5 has a rotating hole 51 formed at the center of the circle. The rotating shaft 3 is inserted into the rotating hole 51. The diameter of the rotating hole 51 is approximately the same as the diameter of the rotating shaft 3. The rotation axis 31 passes through the center of the rotating hole 51. The rotating part 5 has a rack portion 55 in the outer circumference of the circle. In the description of the rotating part 5, the direction extending radially from the rotation axis 31 is referred to as the radial direction, the side of the radial direction toward the rotation axis 31 is referred to as the inner side, and the side away from the rotation axis 31 is referred to as the outer side.

[0023] The rotating part 5 has grooves 52 formed in the radial direction that penetrate the plate surface of the rotating part 5. The groove 52 extends in a curved shape in the direction surrounding the rotating hole 51. The groove 52 is curved so as to protrude towards the outer circumference of the rotating part 5. The rotational force transmission part 6 is inserted into the groove 52. The groove 52 has a cam groove 53 that extends in a curved shape different from a circular arc centered on the rotation axis 31, and an arc groove 54 that extends in a circular arc shape centered on the rotation axis 31. The cam groove 53 is located on one side in the circumferential direction centered on the rotation axis 31, and the arc groove 54 is located on the other side. The cam groove 53 and the arc groove 54 are connected. The part of the groove 52 where the cam groove 53 and the arc groove 54 are connected is denoted as the connection position 52c. The end of the groove 52 opposite to the connection position 52c of the cam groove 53 is denoted as the first end 52a, and the end of the arc groove 54 opposite to the connection position 52c is denoted as the second end 52b.

[0024] The cam groove 53 extends in a curved shape that gradually curves radially inward from the connection position 52c toward the first end 52a. The inner edge 52d of the first end 52a of the cam groove 53 is formed in an arc shape corresponding to the outer shape of the rotational force transmission section 6. Of the inner edge 52d of the first end 52a of the cam groove 53, the radially outer portion is referred to as the first rotational cam curve portion 531, and the radially inner portion is referred to as the second rotational cam curve portion 532. Of the inner edge of the cam groove 53, the radially inner portion adjacent to the second rotational cam curve portion 532 is referred to as the first linear movement cam curve portion 533, and the radially outer portion adjacent to the first rotational cam curve portion 531 is referred to as the second linear movement cam curve portion 534.

[0025] When the fixing part 2, the hook part 4, and the rotating part 5 are arranged overlapping in the thickness direction Z, the fixing hole 22, the elongated hole 44 of the hook part 4, and the rotating hole 51 overlap in the thickness direction Z, and the rotating shaft part 3 is inserted into these holes. The fixing part 2 and the rotating shaft part 3 are each fixed to the base 15. The fixing part 2 does not rotate around the rotation axis 31. The hook part 4 is rotatable around the rotation axis 31 of the rotating shaft part 3 and can move within the length range of the elongated hole 44 relative to the rotating shaft part 3. The rotating part 5 is rotatable around the rotation axis 31.

[0026] When the fixing part 2, hook part 4, and rotating part 5 are arranged overlapping in the thickness direction Z, the first guide groove part 23, hook hole part 45, and cam groove part 53 overlap in the thickness direction Z, and the rotational force transmission part 6 is inserted into these holes. The rotational force transmission part 6 is movably supported on the base 15. The fixing part 2 and the rotational force transmission part 6 can move relative to each other within the length range of the first guide groove part 23. The hook portion 4 is rotatable around the axis of the rotational force transmission portion 6. The rotating portion 5 and the rotational force transmission portion 6 can move relative to each other within the area inside the cam groove portion 53.

[0027] When the fixing portion 2 and the hook portion 4 are positioned overlapping in the thickness direction Z, the guided portion 43 of the hook portion 4 is inserted into the second guide groove portion 24 of the fixing portion 2. The hook portion 4 is movable relative to the fixing portion 2 within the length range of the second guide groove portion 24.

[0028] As shown in Figures 4 and 14, in the unlocked state, when the lock 1 releases the restraint between the vertical frame 16a of one sliding door 16 and the vertical frame 16b of the other sliding door 16, the hook portion 42 of the hook portion 4 is located on one side in the vertical direction Y and is separated from the receiving member 14. In Figures 14 to 17, the rotating shaft portion 3 and the rotational force transmission portion 6 are shown with hatching. In the unlocked state, the rotational force transmission portion 6 is positioned at the first end 23a of the first guide groove portion 23. The guided portion 43 of the hook portion 4 is positioned at the first end 24a of the second guide groove portion 24. The elongated hole portion 44 of the hook portion 4 has its length in the vertical direction Y. The rotating shaft portion 3 is positioned at the first end 44a of the elongated hole portion 44 of the hook portion 4. The rotating portion 5 and the rack portion 55 are located on the other side in the vertical direction Y. The rotational force transmission portion 6 is positioned at the first end 52a of the cam groove portion 53.

[0029] When the rotating part 5 rotates in one direction (in the direction of arrow A1 in Figure 14) from the unlocked state, the rotational force transmission part 6 is pushed by the first rotational cam curve portion 531 of the cam groove portion 53 of the rotating part 5 and rotates together with the rotating part 5 around the rotation axis 31 until the rotating part 5 has rotated 90° from the unlocked state. The rotational force transmission part 6 moves from the first end portion 23a of the first guide groove portion 23 to the switching position 23c. As shown in Figures 5 and 15, the hook portion 4 also rotates 90° around the rotation axis 31 along with the rotation of the rotational force transmission part 6. When the hook portion 4 has rotated 90°, the hook portion 42 of the hook portion 4 is hooked onto the receiving member 14. The state in which the rotating part 5 has rotated 90° from the locked state and the hook portion 42 of the hook portion 4 is hooked onto the receiving member 14 is described as the locked state. When the hook portion 4 rotates 90° from the unlocked position, the guided portion 43 of the hook portion 4 also moves from the first end portion 24a of the second guide groove portion 24 to the switching position 24c. The elongated hole portion 44 of the hook portion 4 has its length direction as the horizontal direction X. The rotating shaft portion 3 is positioned at the first end portion 44a of the elongated hole portion 44 of the hook portion 4.

[0030] As the rotating part 5 rotates further in the rotational direction from the locked state, the rotational force transmission part 6 is pushed to one side in the vertical Y direction and one side in the horizontal X direction by the first linear movement cam curve portion 533 of the cam groove portion 53 of the rotating part 5 until the rotating part 5 rotates 45° from the locked state. The rotational force transmission part 6 is positioned at the switching position of the first guide groove portion 23, and one side in the vertical Y direction is in contact with the edge portion 232a of the first linear portion 232 of the first guide groove portion 23, so it moves along this edge portion 232a to one side in the horizontal X direction. When the rotational force transmission part 6 moves to one side in the horizontal X direction, the hook portion 4 also moves to one side in the horizontal X direction. When the hook portion 4 moves to one side in the horizontal X direction, the elongated hole portion 44 moves to one side in the horizontal X direction, and as shown in Figure 16, the rotating shaft portion 3 is positioned at the second end portion 44b of the elongated hole portion 44. The guided portion 43 of the hook portion 4 also moves to one side in the lateral direction X and is positioned at the second end 24b of the second guide groove portion 24. The rotational force transmission portion 6 moves the cam groove portion 53 and is positioned at the connection position 52c between the cam groove portion 53 and the arc groove portion 54. As the hook portion 4 moves to one side in the lateral direction X, the receiving member 14 to which the hook portion 42 is hooked and the fixing portion 2 move closer together, and the vertical frame 16a and vertical frame 16b are pulled closer. The state in which the rotating portion 5 rotates 45° from the locked state and the vertical frame 16a and vertical frame 16b are pulled closer is described as the pulled-closed state.

[0031] The rotating part 5 can rotate a further 45° to one side in the direction of rotation from the fully engaged state. The rotational force transmission part 6 is positioned at the connection point 52c between the cam groove 53 and the arc groove 54, so even when the rotating part 5 rotates, it is positioned in the arc groove 54 that extends in the direction of rotation, and only the rotating part 5 rotates. The rotational force transmission part 6 does not rotate around the rotation axis 31 together with the rotating part 5, and the hook part 4 does not move either. As shown in Figures 6 and 17, when the rotational force transmission part 6 is positioned at the second end 52b of the groove 52 of the rotating part 5, the rotation of the rotating part 5 stops. The state in which the rotation of the rotating part 5 stops is referred to as the fully locked state.

[0032] To unlock from the locked state, the rotating part 5 is rotated in the opposite direction to the locking direction (in the direction of arrow A2 in the figure). While the rotating part 5 shown in Figure 17 rotates from the locked state to the pulled-in state shown in Figure 16, the rotational force transmission part 6 is located in the arc groove 54, so the rotational force of the rotating part 5 is not transmitted to the rotational force transmission part 6. When the rotating part 5 rotates to the position where it is pulled in, the rotational force transmission part 6 is positioned at the connection position 52c of the cam groove 53.

[0033] As the rotating part 5 is further rotated, the rotational force transmission part 6 is pushed toward the other side in the lateral direction X and the other side in the vertical direction Y by the second linear moving cam curved part 534 of the cam groove part 53. The rotational force transmission part 6 is located at the second end 23b of the first guide groove part 23, and the edge 232b of the first linear part 232 is in contact with the other side in the vertical direction Y. The rotational force transmission part 6 is constrained to move toward the other side in the vertical direction Y and moves toward the other side in the lateral direction X along the edge 232b. As the rotational force transmission part 6 moves toward the other side in the lateral direction X, the hook part 4 moves toward the other side in the lateral direction X, as shown in Figure 15. As the hook part 4 moves toward the other side in the lateral direction X, the pulling of the vertical frame 16a and vertical frame 16b by the hook part 4 is released. The rotational force transmission part 6 is located at the first end 52a of the cam groove part 53.

[0034] As the rotating part 5 is rotated further, the rotational force transmission part 6 is pushed by the second rotational cam curved part 532 of the cam groove part 53 and rotates together with the rotating part 5 around the rotation axis 31. The hook part 4 also rotates, and the hook part 42 separates from the receiving member 14, resulting in the unlocked state.

[0035] As shown in Figure 3, the bottom 111a of the lock housing 111 has two mounting holes 111b, spaced apart in the vertical direction Y. The mounting holes 111b are elongated slits in the horizontal direction X, which is the indoor / outdoor direction when attached to the vertical frame 16a. As shown in Figure 18, the bottom 111a of the lock housing 111 is positioned on the surface 16f of the vertical frame 16a facing the thickness direction Z, which is the width direction. The screw 111c is inserted through the mounting hole 111b and screwed into the screw hole 16g of the vertical frame 16a. In this way, the electric lock 110 is attached to the vertical frame 16a.

[0036] As shown in Figure 1, the opening / closing device 7 is attached to the top of the two sliding doors 16, 16. As shown in Figure 19, the opening / closing device 7 includes an opening / closing device unit 71, a fixing part 72, a cover part 73, and a connecting member 74.

[0037] The opening / closing device unit 71 has a well-known structure. In the opening / closing device unit 71, for example, a pair of pulleys, which are spaced apart in the width direction with the indoor / outdoor direction as their axis (not shown), are rotated by an opening / closing motor. A belt is wrapped around the pair of pulleys. As the pulleys rotate, the belt also rotates along with the pulleys. A connector 71a is provided on the belt. The connector 71a moves in the width direction as the belt rotates.

[0038] The fixing portion 72 has a first plate portion 721 and a second plate portion 722. The first plate portion 721 is attached to the front of the opening / closing device unit 71 by a mounting bracket 721a. The second plate portion 722 extends outward from the upper end of the first plate portion 721. The second plate portion 722 is positioned above the opening / closing device unit 71. The second plate portion 722 is attached to the building structure from the lower surface of the upper frame 17 by a mounting bracket 722b. The fixing portion 72 corresponds to the building structure fixing bracket of the claim.

[0039] The cover portion 73 is provided so as to cover the area below the fixing portion 72 and the area in front of the first plate portion 721 of the fixing portion 72.

[0040] The connecting member 74 includes a first connecting member 741 and a second connecting member 742. The first connecting member 741 and the second connecting member 742 have a roughly L-shape in cross-section along the indoor / outdoor direction and the vertical direction. The first connecting member 741 is connected to a connector 71a. The first connecting member 741 and the second connecting member 742 are connected by the connector 741a. A hook-and-loop fastener 742e is attached to the outdoor-facing side of the second connecting member 742. A hook-and-loop fastener 16e is attached to the indoor-facing side of the upper frame 16c of the indoor-side shoji screen 16. The hook-and-loop fasteners 742e and 16e are fixed together. The opening and closing device unit 71 is detachably attached to the upper frame 16c of the indoor-side shoji screen 16 via the connecting member 74, the hook-and-loop fasteners 742e and 16e. As a result, the indoor-side sash 16 moves in the width direction in conjunction with the movement of the connector 71a of the opening / closing device unit 71. The second connecting member 742 corresponds to the first bracket of the claim. The first connecting member 741 corresponds to the second bracket of the claim. The hook-and-loop fastener 742e corresponds to the second hook-and-loop fastener of the claim. The hook-and-loop fastener 16e corresponds to the first hook-and-loop fastener of the claim.

[0041] As shown in Figure 1, the transmitting unit 8 transmits a signal to the first control unit 91 of the control device 9, which will be described later. When the user chooses to open the sliding door 16 using the transmitting unit 8, an open signal is transmitted to the first control unit 91. When the user chooses to close the sliding door 16 using the transmitting unit 8, a closed signal is transmitted to the first control unit 91.

[0042] The transmitting unit 8 is operated by the user, for example. For example, the transmitting unit 8 may be a remote control, a mobile terminal, a switch, etc. If the transmitting unit 8 is a remote control, a mobile terminal, etc., it communicates wirelessly with the transmitting unit-side communication unit 91-A of the control device 9, which will be described later. If the transmitting unit 8 is a switch, etc., it is connected to the control device 9 by a wire.

[0043] The control device 9 includes a first control unit 91 and a second control unit 92. The first control unit 91 is provided in the opening / closing device 7. As shown in Figure 3, the second control unit 92 is housed inside the electric lock 110. The second control unit 92 corresponds to the lock-side control unit of the claim.

[0044] As shown in Figure 21, the first control unit 91 includes a transmitting unit side communication unit 91-A, an electric lock side communication unit 91-B, an opening / closing device control unit 91-C, an opening / closing device drive unit 91-D, an obstacle response unit 93, and a speed adjustment unit 94. The transmitting unit side communication unit 91-A corresponds to the receiving unit of the claim.

[0045] The transmitting unit communication unit 91-A receives the open and closed signals from the transmitting unit 8 and transmits the open and closed signals to the opening / closing device control unit 91-C. The electric lock side communication unit 91-B transmits an unlocking signal to the second control unit 92 to unlock the electric lock 110 and a locking signal to lock it, and receives a completion signal when the unlocking of the electric lock 110 is complete. Based on the open and closed signals received from the transmitting unit communication unit 91-A, the opening / closing device control unit 91-C transmits a drive signal for the opening / closing motor to the opening / closing device drive unit 91-D. Based on the drive signal for the opening / closing motor received from the opening / closing device drive unit 91-D, the opening / closing device drive unit 91-D drives the opening / closing motor to move the opening / closing device 7, moving the connector 71a (see Figure 19) in the opening direction when the sliding door 16 opens, or moving the connector 71a in the closing direction when the sliding door 16 closes.

[0046] As shown in Figure 22, the second control unit 92 includes a communication unit 92-A, an electric lock control unit 92-B, and an electric lock operating drive unit 92-C.

[0047] The communication unit 92-A receives unlocking and locking signals from the electric lock-side communication unit 91-B of the first control unit 91. The communication unit 92-A transmits a completion signal to the electric lock-side communication unit 91-B indicating that the unlocking of the electric lock 110 is complete. Based on the unlocking and locking signals received from the communication unit 92-A, the electric lock control unit 92-B transmits a drive signal for the drive unit 113 to the electric lock drive unit 92-C. Based on the drive signal received from the electric lock control unit 92-B, the electric lock drive unit 92-C drives the drive unit 113 to unlock and lock the electric lock 110.

[0048] When the sliding door 16 is closed and the user chooses to open it using the transmitting unit 8, the transmitting unit 8 sends an open signal to the transmitting unit-side communication unit 91-A of the first control unit 91. The transmitting unit-side communication unit 91-A receives the open signal. Based on the open signal, the transmitting unit-side communication unit 91-A sends an unlock signal to the communication unit 92-A of the second control unit 92. The communication unit 92-A receives the unlock signal. Based on the unlock signal, the electric lock control unit 92-B drives the electric lock operating drive unit 92-C to unlock the electric lock 110. The communication unit 92-A sends a completion signal to the electric lock-side communication unit 91-B of the first control unit 91 indicating that the unlocking of the electric lock 110 is complete. The electric lock-side communication unit 91-B receives the completion signal. The opening / closing device control unit 91-C drives the opening / closing device drive unit 91-D based on the completion signal, causing the sliding door 16 to open via the opening / closing device 7.

[0049] When the sliding door 16 is open and the user chooses to close it using the transmitter 8, the transmitter 8 transmits a close signal to the transmitter-side communication unit 91-A of the first control unit 91. The transmitter-side communication unit 91-A receives the close signal. The opening / closing device control unit 91-C drives the opening / closing device drive unit 91-D based on the close signal, causing the sliding door 16 to close via the opening / closing device 7. The electric lock-side communication unit 91-B transmits a lock signal to the communication unit 92-A of the second control unit 92 once the closing operation of the sliding door 16 is complete. The communication unit 92-A receives the lock signal. The electric lock drive unit 92-C drives the electric lock drive unit 92-C based on the lock signal to lock the electric lock 110.

[0050] The electric lock control unit 92-B measures and records in advance the state in which the lock 1 is fully pulled in and the state in which it is unlocked, and stores this information in a memory unit (not shown). When the lock is pulled in or unlocked during the current closing operation, the current state is compared with the state stored in the memory unit. If the comparison determines that the locking is complete, an instruction is output to the electric lock control unit 92-B to prevent the lock 1 from rotating or pulling in any further from that state. When the lock is unlocked during the current operation, the current state is compared with the state stored in the memory unit. If the comparison determines that the unlocking is complete, an instruction is output to the electric lock control unit 92-B to prevent the lock 1 from rotating or pulling in any further from that state.

[0051] As shown in Figure 23, for example, the transmitting unit 8A may be a communication unit installed inside a house. The transmitting unit 8A may be configured to use a motion sensor to determine when a user is approaching and to transmit an open signal to the first control unit 91. The transmitting unit 8A may be configured to use the location information of a mobile terminal in conjunction with a proximity sensor to recognize when a user is approaching and to transmit an open signal to the first control unit 91.

[0052] As shown in Figure 25, the obstacle response unit 93 includes a detection unit 93-A, a measurement unit 93-B, a reference value storage unit 93-C, a learning function unit 93-D, a moving average calculation unit 93-E, a difference value calculation unit 93-F, an accumulation unit 93-G, a determination unit 93-H, and a threshold value storage unit 93-I.

[0053] The detection unit 93-A detects the position pulses supplied from the output unit provided on the opening / closing motor of the opening / closing device drive unit 91-D and increments the position information n by 1. Here, the position information n is the number of position pulses supplied from the output unit and is a value indicating the current open / closed position of the sliding door 16. That is, the number of rotations required for the opening / closing motor to move the sliding door 16 from the fully open state to the fully closed state (hereinafter referred to as "number of fully closed rotations") is stored in advance in the storage unit (not shown). Therefore, the current open / closed position of the sliding door 16 can be determined from the number of position pulses indicating that the opening / closing motor has rotated once. The detection unit 93-A outputs the position pulses and position information n to the measurement unit 93-B.

[0054] The measurement unit 93-B measures the load on the opening / closing motor. For example, the measurement unit 93-B acquires position pulses and position information n from the detection unit 93-A. The measurement unit 93-B measures the pulse width of the position pulse for each piece of position information n. The pulse width of the position pulse increases as the rotation speed of the opening / closing motor decreases, and conversely, the pulse width decreases as the rotation speed of the opening / closing motor increases. For example, as shown in Figure 24, when the sliding door 16 comes into contact with an obstacle a, a load is placed on the opening / closing motor. When a load is placed on the opening / closing motor, the rotation speed of the opening / closing motor decreases, and the pulse width of the position pulse increases. Therefore, the measurement unit 93-B shown in Figure 25 calculates the pulse width of the opening / closing motor as the load by measuring the pulse width of the position pulse for each position pulse (for each count value) supplied from the detection unit 93-A.

[0055] The measurement unit 93-B outputs position information n and the pulse width An of the position pulse corresponding to that position information n to the moving average calculation unit 93-E. The measurement unit 93-B also stores the position information n and the pulse width of the position pulse corresponding to that position information n in the reference value storage unit 93-C, associating them together.

[0056] The reference value storage unit 93-C stores the position information n and the pulse width of the position pulse calculated for each fully opening operation in which the sliding door 16 transitions from a fully closed state to a fully open state, or for each fully closing operation in which it transitions from a fully open state to a fully closed state. In other words, the reference value storage unit 93-C stores past position information n and pulse width of the position pulse (hereinafter referred to as "past data"). Past data is stored in the reference value storage unit 93-C when no obstacle a is detected during the opening and closing operation. The past data stored in the reference value storage unit 93-C is, for example, past position information n and pulse width of the position pulse for multiple fully opening or fully closing operations in the past, relative to the present.

[0057] The learning function unit 93-D has the function of determining the reference value load Bn based on past data stored in the reference value storage unit 93-C. Specifically, for example, the learning function unit 93-D has a learning function that determines the pulse width of the position pulse corresponding to the position information n based on past data from multiple past events. The learning function unit 93-D obtains the pulse width of the position pulse corresponding to the position information n from past data from multiple past events. The learning function unit 93-D selects the second smallest pulse width data from the stored pulse width data of multiple position pulses for each position information n. The learning function unit 93-D stores the selected pulse width of the position pulse corresponding to the position information n as the reference value load Bn.

[0058] The moving average calculation unit 93-E acquires position information n and the pulse width An of the position pulse corresponding to the position information n from the measurement unit 93-B. The moving average calculation unit 93-E acquires the reference value load Bn corresponding to the acquired position information n from the learning function unit 93-D. The moving average calculation unit 93-E calculates the moving average values ​​of the pulse width An and the reference value load Bn for each position information n. The moving average calculation unit 93-E corrects (normalizes) the pulse width An and the reference value load Bn in order to optimize the acquired data which may change due to environmental changes, etc. The moving average calculation unit 93-E outputs the calculated corrected value αn to the difference value calculation unit 93-F.

[0059] The difference value calculation unit 93-F obtains a correction value αn from the moving average calculation unit 93-E. The difference value calculation unit 93-F removes inappropriate data from the current switching data and calculates the load difference value Cn. The load difference value Cn can be considered as the load of the switching motor with highly reproducible noise removed. The difference value calculation unit 93-F outputs the calculated load difference value Cn to the integration unit 93-G.

[0060] The integration unit 93-G obtains the load difference value Cn from the difference value calculation unit 93-F. The integration unit 93-G compares the load difference value Cn with the integration threshold P and outputs the comparison result to the determination unit 93-H.

[0061] The determination unit 93-H obtains a determination threshold Q from the threshold storage unit 93-I. The determination unit 93-H determines whether the current opening and closing operation is normal or abnormal by determining whether the comparison result supplied from the integration unit 93-G exceeds the determination threshold Q. If it determines that it is abnormal, it outputs a control signal to the opening and closing device control unit 91-C. For example, the control signal may be a signal to stop the rotation of the opening and closing motor or a signal to reverse the rotation of the opening and closing motor.

[0062] As shown in Figure 26, the speed adjustment unit 94 includes a detection unit 94-A, a measurement unit 94-B, a reference value storage unit 94-C, a learning function unit 94-D, an operating position calculation unit 94-E, an operating position correction unit 94-F, and a speed instruction unit 94-G.

[0063] The detection unit 94-A, the measurement unit 94-B, and the reference value storage unit 94-C have the same configuration as the detection unit 93-A, the measurement unit 93-B, and the reference value storage unit 93-C of the obstacle response unit 93, respectively, and their explanation is omitted.

[0064] The learning function unit 94-D calculates the pulse width of the position pulse corresponding to the position information n based on past data stored in the reference value storage unit 94-C.

[0065] The operating position calculation unit 94-E compares the position information n supplied from the measurement unit 94-B with the pulse width An of the position pulse corresponding to that position information n supplied from the learning function unit 94-D.

[0066] The operating position correction unit 94-F acquires comparison data from the operating position calculation unit 94-E. Based on the comparison results, the operating position correction unit 94-F corrects the pulse width of the position pulse at the current opening / closing time and determines the position information at the current opening / closing time.

[0067] The speed instruction unit 94-G outputs information to the opening / closing device control unit 91-C that changes the speed of the opening / closing motor at a predetermined position, based on the position information calculated by the operating position correction unit 94-F.

[0068] When the electric lock 110 attempts to unlock based on an unlocking signal, if the relative positions of the hook portion 4 and the receiving member 14 are misaligned and unlocking is not possible, the second control unit 92 transmits error information to the first control unit 91. The error information may also be notified to the user via a transmission unit 8 or the like.

[0069] When the electric lock 110 attempts to lock based on a locking signal, if the relative positions of the hook portion 4 and the receiving member 14 are misaligned and the lock cannot be secured, the second control unit 92 transmits error information to the first control unit 91. The error information may also be notified to the user via a transmission unit 8 or the like.

[0070] Initially, the sliding door 16 is moved to the fully closed position. From this position, the transmitter 8 is operated to open the sliding door 16 and move it to the fully open position. The load when the sliding door 16 and the vertical frame of the frame 10 come into contact at the fully open position is detected and the fully open position is recorded. The sliding door 16 is moved back to the fully closed position and the contact between the sliding door 16 and the vertical frame of the frame 10 at the fully closed position is detected to check for any deviation from the initial position. The sliding door 16 is moved back to the fully open position and moved to the position recorded in the first opening operation to check for any deviation and make corrections. After that, the sliding door 16 is moved back to the fully closed position to complete the initial setup.

[0071] This section describes how to replace an existing manual crescent lock 200 with an electric lock 110. As shown in Figure 27, remove the screw cover 201 from the crescent lock body 202. Loosen the screw 203 that is screwed into the screw hole 16g of the vertical frame 16a, and remove the crescent lock body 202 from the vertical frame 16a. As shown in Figure 18, using the existing screw hole 16g, insert the screw 111c through the mounting hole 111b of the electric lock 110 and screw it into the screw hole 16g. At this time, since the mounting hole 111b is an elongated hole that is long in the indoor / outdoor direction, the indoor / outdoor mounting position of the electric lock 110 can be adjusted.

[0072] In the electric lock-equipped door system 100 configured in this way, the electric lock 110 can be installed using the screw hole 16g where the existing manual crescent lock 200 was installed. Since the mounting hole 111b of the electric lock 110 is an elongated hole that is long in the indoor and outdoor directions, the mounting position of the electric lock 110 in the indoor and outdoor directions can be adjusted according to the degree of engagement with the receiving member 14.

[0073] The opening / closing device unit 71 of the opening / closing device 7 is connected to the upper frame 16c of the indoor-side sliding door 16 via hook-and-loop fasteners 742e and 16e. The opening / closing device 7 can be easily attached to the upper frame 16c without the need for screw fastening or other such work.

[0074] Since the transmitting unit 8 and the receiving unit 91-A of the control device 9 communicate wirelessly, wiring work is unnecessary, and the appearance can be improved because the wiring is not exposed.

[0075] Preferred embodiments of this disclosure have been described above with reference to the attached drawings, but it goes without saying that this disclosure is not limited to these examples.
