[0008] An embodiment of an electrically operated window will be described with reference to the drawings, using an example of an internally operated single sliding window device in which the internal sliding screen can be electrically slid open and closed. In the following description, the directions used to explain each device are those when the device is installed in an opening in a building.

[0009] As shown in Figure 1, the internally movable single sliding window device of this embodiment comprises an internally movable single sliding window 1, an electric opening and closing device 2 that drives the inner shroud 12 of the internally movable single sliding window 1 to open and close, a connecting device 3 that connects the electric opening and closing device 2 and the inner shroud 12, an electric crescent 4 that keeps the inner shroud 12 in a closed position, a detection device 5 that detects outdoor wind speed and rainfall, a control unit 6 that controls the electric opening and closing device 2 and the electric crescent 4, and an operating device 7 that operates the electric internally movable single sliding window.

[0010] -Inner sliding window- As shown in Figure 1, the internal sliding window 1 has a frame body 11 that is placed in an opening in a building, an outer shoji screen 13 that is fixed to the left side of the inner periphery of the frame body 11 when viewed from the inside of the room, and an inner shoji screen 12 that is placed on the inner periphery of the frame body 11 so that it can slide freely in the left-right direction.

[0011] The frame body 11 is formed by assembling an upper frame 111, a lower frame 112, and left and right vertical frames 113, 114, all of which are made of a metal material such as aluminum, around the four periphery. The inner and outer shoji screens 12, 13 are formed by attaching a panel of glass or the like to the inner periphery of a frame body consisting of an upper frame 121 (the upper frame of the outer shoji screen 13 is not numbered) made of a metal material such as aluminum, a lower frame 122, 132, a left vertical frame 123, 133, and a right vertical frame 124, 134 assembled around the four sides.

[0012] -Electric switchgear- As shown in Figures 1 and 2(a) and (b), the electric opening and closing device 2 has an electric device 21 fixed to the left end of the upper frame 111, a slide rail 22 arranged along the left-right (longitudinal) direction on the indoor side of the upper frame 111 and supported so as to be freely rotatable, a bridge member (engaged member) 23 arranged so as to be freely movable in the left-right (longitudinal) direction on the indoor side of the upper frame 111 and which moves left-right along the upper frame 111 as the slide rail 22 rotates, and a bracket 24 and bearing 25 for attaching the electric device 21 and slide rail 22 to the indoor side of the upper frame 111.

[0013] The electric opening and closing device 2 also has a closed detection sensor 26a, a partially open detection sensor 26b, and a fully open detection sensor 26c, which are limit switches that detect the open or closed state of the inner screen 12 when the bridge member 23 moves left or right and comes into contact with them.

[0014] The bracket 24 is a long, horizontally elongated member made of a metal material such as steel, and as shown in Figures 2(c)(d) and 3(c)(d), it has a facing portion 24a and an upper wall portion 24b whose upper end is bent and extends toward the indoor side.The facing portion 24a is fixed to the upper frame 111 with the facing portion 24a abutting against the indoor side of the indoor facing wall 111a of the upper frame 111 and the upper wall portion 24b abutting against the underside of the angle portion 111b of the upper frame 111.

[0015] The left end of the bracket 24 is formed so that the left end of the visible portion 24a extends further left than the left end of the upper wall portion 24b, and at the left end of the visible portion 24a, an upper support wall 24c and a lower support wall 24d are formed extending toward the interior of the room for mounting the electric device 21. In addition, a bearing 25 is provided at the right end of the bracket 24 to rotatably support the right end of the slide rail 22.

[0016] As shown in Figures 3(a)(b) and 4(a)(b), the electric device 21 has an electric motor section 21a that has an electric motor built in, a power transmission section 21b that transmits the rotation of the electric motor to the slide rail 22, and an attachment section 21c for fixing the electric device 21 to the bracket 24, and one end of the slide rail 22 is held by the power transmission section 21b so that power can be transmitted freely.

[0017] The mounting portion 21c of the electric device 21 is inserted between the upper support wall 24c and the lower support wall 24d of the bracket 24, and the electric device 21 is fixed to the upper frame 111 via the bracket 24 by fixing means such as screws.

[0018] As shown in Figure 2(b), the slide rail 22 is a round rod-shaped member with threads on the surface, and the end on the left vertical frame side is rotatably supported by the power transmission part 21b of the electric device 21, and the end on the right vertical frame side is rotatably supported by the bearing 25, and it rotates forward and backward by the force transmitted from the power transmission part 21b of the electric device 21. A torque limiter 22a is provided on the left side of the slide rail 22, which cuts off the transmission of power when a rotational load of a predetermined magnitude or greater is applied.

[0019] 5(a) and 5(b), bridge member 23 has bridge member main body 23a, which is a short, rectangular block-shaped member made of resin, with screw holes 23b formed through bridge member main body 23a in the left-right direction. Bridge member 23 also has protrusion 23c that protrudes upward from the upper surface of bridge member main body 23a toward the interior of the room, and roller pin 23d attached to the interior side of bridge member main body 23a. Roller pin 23d is attached to bridge member main body 23a via position adjustment base 23e, allowing the attachment position of roller pin 23d to be freely adjusted.

[0020] When the slide rail 22 is passed through the screw hole 23b and screwed into the screw on the surface of the slide rail, the upper surface of the protrusion 23c abuts against the lower surface of the upper wall portion 24b of the bracket 24, allowing the piece member 23 to move left and right without rotating when the slide rail 22 rotates. A space s is formed between the exterior side surface of the bridge member 23 and the facing portion 24a of the bracket 24, and serves as a space for wiring and the like.

[0021] The closed detection sensor 26a, the partially open detection sensor 26b, and the fully open detection sensor 26c are attached at appropriate positions on the underside of the upper wall portion 24b of the bracket 24, as shown in Figure 2(b).A sensor part is provided on the indoor side of each sensor, and the outdoor side of the protrusion 23c of the bridge member 23 abuts against the sensor part, thereby enabling the bridge member 23 to be detected.

[0022] The closed detection sensor 26a detects that the inner shoji screen 12 is in the closed position and outputs a closed signal to the control unit 6. The partial open detection sensor 26b detects that the inner shoji screen 12 is in a partially open position (for example, 300 mm open), and outputs a partial open signal to the control unit 6. The full-open detection sensor 26c detects that the inner shoji screen 12 is in the fully open position and outputs a full-open signal to the control unit 6.

[0023] The electric opening / closing device 2 rotates the slide rail 22 via the power transmission part 21b by rotating the electric device 21 forward or backward, and can move the bridge member 23 in the left-right direction, and the position of the bridge member 23 can be detected by each sensor 26.

[0024] -Connection device- As shown in Figure 1, the connecting device 3 is arranged within the hollow portion of the left vertical frame 123 of the inner shoji screen 12, and has an engaging member 31 that protrudes from the upper end of the left vertical frame 123 into the movement path of the bridge member 23 of the electric opening and closing device 2 and can engage with the bridge member 23, an operating unit 32 that is arranged within the hollow portion of the left vertical frame 123 of the inner shoji screen 12 and can be operated from the indoor side of the left vertical frame 123, and a connecting bar 33 that connects the operating unit 32 and the engaging member 31, allowing the engaging member 31 to move up and down using the operating unit 32.

[0025] As shown in Figures 5(a)(b) and 6, the engaging member 31 has a latch plate 311 that can engage with the roller pin portion 23d of the bridge member 23, a connecting plate 312 that supports the latch plate 311 so that it can move freely up and down, and a resin sleeve 313 that is arranged between the connecting plate 312 of the latch plate 311 and reduces friction when the latch plate 311 moves up and down.

[0026] The latch plate 311 is made of a metal material such as steel, and as shown in Figures 6(a) and (b), has a flat main body 311a, left and right side wall portions 311b, 311b formed by bending both left and right side edges of the main body 311a toward the outdoors, and a spring bearing portion 311c that bends from the center of the lower end of the main body 311a toward the outdoors and extends toward the outdoors.

[0027] An engagement groove 311d that opens upward and can engage with the roller pin portion 23d of the bridge member 23 is formed in the upper center of the main body 311a of the latch plate 311, and inclined portions 311e, 311e that slope downward as they extend outward are formed on both the left and right sides of the engagement groove 311d of the main body 311a.

[0028] In addition, the latch plate 311 has screw holes 311f, 311f arranged vertically in the center of the main body 311a for fixing the sliding pin 314, and mating holes 311g for fixing the resin slat 313 are formed in the four corners of the outdoor side surface of the main body 311a.

[0029] The resin sleeve 313 is made of a resin material such as polyacetal, and has a main body 313a that is arranged on the outdoor side of the main body 311a of the latch plate 311, and engaging arms 313b, 313b formed on the outdoor side on both the left and right sides of the main body 313a. The resin sleeve 313 has holes 313c, 313c formed in the center of the main body 313a to match the screw holes 311f, 311f of the latch plate 311, and protrusions 313d that fit into the fitting holes 311g of the latch plate 311 are formed at the four corners of the indoor side of the main body 313a.

[0030] Then, the body 313a of the resin slit 313 is abutted against the body 311a of the latch plate 311 from the outdoor side, and the protrusion 313d of the resin slit 313 is fitted into the fitting hole 311g of the body 311a of the latch plate 311, and the engaging arms 313b, 313b of the resin slit 313 are engaged with the side wall portions 311b, 311b of the latch plate 311, thereby attaching the resin slit 313 to the outdoor side of the latch plate 311.

[0031] The connecting plate 312 is made of a metal material such as steel, and as shown in Figures 6(e), (f), and (g), has a flat main body 312a and left and right side wall portions 312b, 312b formed by bending both left and right side edges of the main body 312a toward the outside. The connecting plate 312 has a rectangular hole 312c formed in the approximate center of the main body 312a, and a spring receiving portion 312d bent from the bottom side of the hole 312c and extending to the outside.

[0032] The connecting plate 312 has two vertically aligned elongated holes 312e, 312e formed above the hole 312c of the main body 312a, and three vertically aligned screw holes 312f formed below the hole 312c.

[0033] 6(h), (i), and (j), the spacing between engaging arms 313b of resin sleeve 313 attached to latch plate 311 is wider than the spacing between left and right side walls 312b of connecting plate 312. Latch plate 311 with resin sleeve 313 attached is abutted against main body 312a of connecting plate 312 from the indoor side, and sliding pins 314 are fixed to screw holes 311f of latch plate 311 through elongated holes 312e from the outdoor side of connecting plate 312, thereby making latch plate 311 integral with connecting plate 312 and movable up and down. Note that, to fix sliding pins 314 to latch plate 311, sliding pins 314 may be screwed into screw holes 311f, or caulking may be used.

[0034] The sliding pins 314, 314 have heads 314a that are larger than the short sides of the elongated holes 312e, 312e of the connecting plate 312, so that the sliding pins 314, 314 will not come out of the elongated holes 312e, 312e.

[0035] A spring member 315 is arranged between the spring receiving portion 311c of the integrated latch plate 311 and the spring receiving portion 312d of the connecting plate 312, so that the latch plate 311 can move freely up and down relative to the connecting plate 312 and is biased upward, thereby forming an engaging member 31.

[0036] As shown in Figure 7, the operating unit 32 has a guide member 321 made of a metal material such as aluminum alloy and having an approximately rectangular hollow section, an operating lever 322 arranged so as to be freely movable up and down on the indoor side of the left vertical frame 123 of the inner shoji screen 12, a spring holding member 323 made of a metal material such as steel and fixed within the hollow section of the guide member 321, and an operating piece 324 made of a resin material and held by the spring holding member 323 so as to be freely movable up and down and connected to the operating lever 322.

[0037] The guide member 321 is arranged in the hollow portion of the left vertical frame 123 of the inner shoji screen 12, near the interior side of the room, at a location where the operating unit 32 is arranged, and is fixed by a screw b1 or the like. The guide member 321 has an elongated hole 321a formed in the interior wall thereof, through which the connecting portion 322c of the operating lever 322 passes.

[0038] The operating lever 322 is made of a resin material and has a main body portion 322b that is arranged on the indoor side of the left vertical frame 123 and is held so that it can move freely up and down by a guide cover 325, a lever portion 322a that protrudes toward the indoor side of the guide cover 325, and a connecting portion 322c that protrudes from the outdoor side of the main body portion 322b to the outdoor side. The connecting portion 322c of the operating lever 322 passes through an elongated hole formed in the indoor side wall of the left vertical frame 123 and an elongated hole 321a formed in the indoor side wall of the guide member 321, and reaches the hollow interior of the guide member 321. The operating lever 322 may be biased upward by a spring 322d disposed between the operating lever 322 and the guide cover 325.

[0039] The spring retaining member 323 is made of a metal material such as steel, and has an outdoor side wall portion 323a, left and right side wall portions 323b, 323b that are continuous with the left and right sides of the outdoor side wall portion 323a and bent indoors, and a bottom wall portion 323c that is continuous with the lower end of the outdoor side wall portion 323a and bent indoors, and is fixed inside the hollow portion of the guide member 321 with screws b2 or the like. The spring holding member 323 has a bottom wall portion 323c formed with a through-hole 323e through which the lower end of the operating piece 324 passes.

[0040] The operating piece 324 is made of a resin material and has a main body portion 324a that is guided inside the spring holding member 323 so that it can move freely up and down, a connecting bar mounting portion 324b that is continuous with the upper part of the main body portion 324a, and a guide rod portion 324c that is continuous with the lower part of the main body portion 324a. The operating piece 324 has a fitting hole 324d formed in the center of the main body 324a, which penetrates in the indoor / outdoor direction and into which the connecting portion 322c of the operating lever 322 fits, and above and below the fitting hole 324d, long holes 324e, 324e are formed which penetrate in the left-right direction and are long in the vertical direction.

[0041] The operating piece 324 is arranged in the space formed by the outdoor side wall portion 323a and the left and right side wall portions 323b, 323b of the spring holding member 323 so that the guide rod portion 324c passes through the through hole 323e of the spring holding member 323, and pin members 323f fixed to the left and right side wall portions 323b, 323b of the spring holding member 323 are inserted into the long holes 324e, 324e formed in the main body portion 324a of the operating piece 324, so that the operating piece 324 is arranged to be freely movable up and down relative to the spring holding member 323.

[0042] A spring member 326 is disposed between a main body portion 324a of the operating piece 324 and a bottom wall portion 323c of the spring holding member 323, and the operating piece 324 is held in a state in which it is biased upward relative to the spring holding member 323.

[0043] The operating lever 322 has a connecting portion 322c that passes through the long hole 321a of the guide member 321 and is fitted into a fitting hole 324d of the operating piece 324 held by the spring holding member 323. By operating the operating lever 322 downward, the operating piece 324 can be moved downward against the biasing force of the spring member 326.

[0044] As shown in Figures 5(a)(b) and 7(a)(b), the connecting bar 33 consists of a hollow, elongated member with a roughly rectangular cross section, and its upper end is fixed by a screw b3 or the like to a screw hole 312f of the connecting plate 312 of the engaging member 31 with a screw b3 or the like, and its lower end is fixed by a screw b4 or the like to a connecting bar mounting portion 324b of the operating piece 324 of the operating unit 32, connecting the operating unit 32 and the engaging member 31 and enabling the engaging member 31 to be moved up and down by operating the operating unit 32.

[0045] -Electric Crescent- The electric crescent 4 has a crescent lock fixed to the left vertical frame 123 of the inner shoji 12 and rotated by an electric motor or the like, a crescent receiver fixed to the right vertical frame 124 of the outer shoji 13, and a lock detection sensor 4a that detects whether the electric crescent 4 is in a locked or unlocked state and outputs a signal indicating the locked or unlocked state to the control unit 6, and is a crescent that can be locked and unlocked electrically. The electric crescent 4 can also be operated manually without feeling the load of the electric motor, for example, by providing an electric release switch.

[0046] -Detection device- The detection device 5 of this embodiment is, for example, a wind speed sensor 501 that detects wind speed and a rainfall sensor 502 that detects the presence or absence of rainfall. Each detection device 5 measures the detection target at predetermined time intervals (for example, every minute) and outputs the detection results to the control unit 6. Note that each detection device 5 may be configured to output the detection results to the control unit 6 when the detection target is detected as a trigger.

[0047] -Control Unit- The control unit 6 of this embodiment is a computer that controls the entire inwardly moving single sliding window device. For example, the control unit 6 opens and closes the inner sliding screen 12 of a sliding window, and locks and unlocks the electric crescent 4 based on information input from each detection device 5.

[0048] -Operation device- The operating device 7 of this embodiment is a device that includes a command button for the inward sliding window, and may be formed integrally with the control unit 6 or may be formed separately. The command buttons provided on the operating device 7 include, for example, an "automatic operation button" and a "manual operation button" for selecting the operation mode of the inward sliding window, as well as an "open button," a "close button," and a "stop button" that are operated during manual operation, and the operating device 7 outputs information regarding the buttons operated by the user to the control unit 6.

[0049] - Engagement and disengagement of bridge member (engaged member) of electric opening and closing device and engaging member of coupling device - In the internally movable single sliding window device of this embodiment, under normal conditions, the operating piece 324, connecting bar 33 and engaging member 31 are urged upward by the repulsive force of the spring member 326 arranged between the bottom wall portion 323c of the spring holding member 323 of the operating unit 32 and the main body portion 324a of the operating piece 324. As shown in FIG. 8(a), the engaging member 31 of the connecting device 3 protrudes into the movement path of the roller pin portion 23d of the bridge member 23, and the engaging groove portion 311d of the latch plate 311 of the engaging member 31 engages with the roller pin portion 23d. Therefore, the left vertical frame 123 of the inner shoji screen 12 can be moved left and right together with the bridge member 23 of the electric opening and closing device 2, and the inner shoji screen 12 can be automatically opened and closed by driving the electric device 21.

[0050] When manually opening or closing the inner shoji screen 12, the operating lever 322 of the operating part 32 is operated downward against the biasing force of the spring member 326, and as shown in Figure 8 (b), the entire engaging member 31 moves downward and moves out of the movement path of the roller pin portion 23d of the bridge member 23, allowing the engagement between the roller pin portion 23d of the bridge member 23 and the engaging groove portion 311d of the latch plate 311 to be released, and the inner shoji screen 12 can be opened or closed manually without feeling the load from the electric device 21 of the electric opening and closing device 2. When the operating lever 322 of the operating unit 32 is released after manually moving the inner screen 12, the engaging member 31 protrudes into the movement path of the roller pin portion 23d of the bridge member 23 due to the biasing force of the spring member 326, as shown in Figure 8 (c).

[0051] The manually opened inner shoji screen 12 can be opened and closed manually, but can also be opened and closed by an electric opening and closing device 2. Specifically, when the electric device 21 of the electric opening / closing device 2 is driven to move the bridge member 23 to a position above the engaging member 31, the roller pin portion 23d of the bridge member 23 eventually abuts against the inclined portion 311e formed on the upper part of the main body portion 311a of the latch plate 311.

[0052] Thereafter, when the bridge member 23 is further moved to a position above the engaging member 31, the roller pin portion 23d climbs onto the inclined portion 311e of the latch plate 311 and pushes down the latch plate 311 against the biasing force of the spring member 315, as shown in Figure 8(d), and eventually the roller pin portion 23d climbs over the inclined portion 311e as shown in Figure 8(e), and the roller pin portion 23d engages with the engaging groove portion 311d as shown in Figure 8(a).

[0053] Furthermore, when the manually opened inner shoji screen 12 is manually closed, the roller pin portion 23d of the bridge member 23 similarly automatically engages with the engaging member 31, thereby enabling subsequent opening and closing by the electric opening and closing device 2.

[0054] As described above, the internally operated single sliding window of this embodiment allows the internal shoji screen 12 to be opened and closed manually without feeling the load from the electric device 21 of the electric opening and closing device 2, and after manual operation, the electric opening and closing device 2 and the connecting device 3 are automatically connected, allowing the internal shoji screen 12 to be opened and closed automatically.

[0055] -Operating mode of the inner sliding window device- The internally movable single sliding window device of this embodiment can be set to two electric opening and closing modes: an automatic operation mode that automatically controls the opening and closing of the internally movable single sliding window 1 based on the detection results of the detection device 5, and a manual operation mode that controls the opening and closing of the internally movable single sliding window 1 in response to user operation, as well as a manual opening and closing mode in which the internally movable single sliding window 1 is opened and closed manually, and the single sliding window can be opened and closed in each mode.

[0056] (Autonomous driving mode) The automatic operation mode is an operation mode in which the opening and closing of the inner sliding window 1 is controlled in accordance with the detection result of the detection device 5. In the automatic operation mode, the control unit 6 of the inward sliding window device executes the process of closing the inward sliding window 1 in bad weather such as strong winds and rain.

[0057] For example, in the automatic operation mode, when the control unit 6 receives a signal from the wind speed sensor 501 indicating that the outdoor wind speed is equal to or higher than a predetermined wind speed, or when the control unit 6 receives a signal from the rainfall sensor 502 indicating that rainfall has been detected, the control unit 6 executes the closing process of the inward sliding window 1.

[0058] In the closing process, the control unit 6 drives the electric device 21 of the electric opening and closing device 2 in the closing direction. Driving the electric device 21 in the closing direction continues until the closing detection sensor 26a detects the closure of the inner sash 12 and outputs a close signal.

[0059] When the control unit 6 receives a close signal output from the close detection sensor 26a, it stops driving the electric device 21 and drives the electric crescent 4 in the locking direction. Driving the electric crescent 4 in the locking direction continues until the lock detection sensor 4a detects that the electric crescent 4 is locked and outputs a lock signal indicating that the electric crescent 4 is locked.

[0060] When the control unit 6 receives the lock signal output from the lock detection sensor 4a, it stops driving the electric crescent 4 and completes the process of closing the inner sliding window 1.

[0061] On the other hand, in the automatic driving mode, the control unit 6 executes the process of partially opening the inward sliding window 1 in fine weather. For example, in the automatic operation mode, if the control unit 6 does not receive a signal from the wind speed sensor 501 indicating that the outdoor wind speed is above a predetermined level and a signal from the rainfall sensor 502 indicating that rain has been detected, it executes a process to partially open the inward sliding window 1.

[0062] In the partial opening process, the control unit 6 drives the electric device 21 of the electric opening / closing device 2 in the closing direction for a predetermined time, and then drives the electric crescent 4 in the unlocking direction. The unlocking operation of the electric crescent 4 continues until the lock detection sensor 4a detects the unlocked state of the electric crescent 4 and outputs an unlock signal indicating that the electric crescent 4 is in the unlocked state.

[0063] When the control unit 6 receives the unlock signal output from the lock detection sensor 4a, it drives the electric device 21 in the opening direction. The driving of the electric device 21 in the opening direction continues until the inner screen 12 is partially opened, the bridge member 23 abuts against the partial opening detection sensor 26b, and a partial opening signal is output, as shown in Figure 9.

[0064] When the control unit 6 receives the partial open signal output from the partial open detection sensor 26b, it stops driving the electric device 21 and completes the partial open process.

[0065] In addition, since there is a possibility of sudden changes in the weather, in automatic operation mode it is preferable to only open the inner sliding window 1 partially (for example, to an opening width of about 300 mm), but it is also possible to keep the inner shoji 12 open until it is fully open.

[0066] (Handheld operation mode) The manual operation mode is an operation mode in which the user can use the operation device 7 to open or close the inner sliding window 1. In the manual operation mode, the control unit 6 executes the process of closing the inward sliding window 1 in bad weather such as strong winds and rain.

[0067] For example, in the manual operation mode, when the control unit 6 receives a signal from the wind speed sensor 501 indicating that the outdoor wind speed is equal to or higher than a predetermined speed, or when the control unit 6 receives a signal from the rainfall sensor 502 indicating that rain has been detected, the control unit 6 executes the closing process of the inward sliding window 1. The closing process in the manual operation mode is the same as the closing process in the automatic operation mode, so a description thereof will be omitted.

[0068] On the other hand, in the manual operation mode, if the control unit 6 does not receive a signal from the wind speed sensor 501 indicating that the outdoor wind speed is above a predetermined level, and if the user operates the "open button" on the operating device 7 to issue a command to open the inner sliding screen 12, the control unit 6 executes the full-open process for the inner sliding window 1.

[0069] In the full-open process, the control unit 6 drives the electric device 21 of the electric opening / closing device 2 in the closing direction for a predetermined time, and then drives the electric crescent 4 in the unlocking direction. The unlocking operation of the electric crescent 4 continues until the lock detection sensor 4a detects that the electric crescent 4 is in an unlocked state and outputs an unlock signal indicating that the electric crescent 4 is in an unlocked state.

[0070] When an unlock signal is input from the lock detection sensor 4a, the control unit 6 drives the electric device 21 in the opening direction. The driving of the electric device 21 in the opening direction continues until the inner screen 12 is fully opened, the bridge member 23 abuts against the full-open detection sensor 26c, and a full-open signal is output, as shown in Figure 10.

[0071] When the control unit 6 receives the full-open signal output from the full-open detection sensor 26c, it stops driving the electric device 21 and completes the full-open process.

[0072] In addition, in the manual operation mode, if the control unit 6 does not receive a signal from the wind speed sensor 501 indicating that the outdoor wind speed is above a predetermined level, and if the user operates the "close button" on the operating device 7 to issue a command to close the inner sliding screen 12, the control unit 6 executes the closing process for the inner sliding window 1. The closing process in the manual operation mode is the same as the closing process in the automatic operation mode, so a description thereof will be omitted.

[0073] In addition, in the manual operation mode, if the wind speed sensor 501 does not input a signal indicating that the outdoor wind speed is above a predetermined level, and the user operates the "stop button" on the operating device 7 to issue a command to stop the inner sliding screen 12, the control unit 6 executes the stop process for the inner sliding window 1 and stops the electric device 21 of the electric opening and closing device 2.

[0074] (Manual opening / closing mode) The internally movable single-sliding window 1 can be switched to manual opening / closing mode by the user operating the operating lever 322 of the connecting device 3 downward to disengage the bridge member 23 of the electric opening / closing device 2 from the engaging member 31 of the connecting device 3. In the manual opening / closing mode, the user can manually open and close the inner shoji screen 12, and can stop it at any position as shown in FIG.

[0075] It is preferable to unlock the electric crescent 4 before operating the operating lever 322 to switch to the manual opening / closing mode. The electric crescent 4 may be unlocked automatically by electric power, or may be unlocked manually.

[0076] With the electric crescent 4 unlocked, the operating lever 322 is operated downward to move the inner shoji 12 to the left, thereby opening the inner shoji 12. In addition, by moving the open inner screen 12 to the closed position, the engaging member 31 of the connecting device 3 can be engaged with the bridge member 23 of the electric opening and closing device 2, and the automatic operation mode or manual operation mode can be restored.

[0077] In addition, the inner shoji screen 12 that is opened in the manual opening / closing mode may be configured to close automatically after a predetermined time, for example. The control unit 6 may be configured to move the bridge member 23 of the electric opening / closing device 2 to a position above the engaging member 31 of the connecting device 3 to engage the bridge member 23 with the engaging member 31 and execute the closing process when a predetermined time has elapsed in the manual opening / closing mode or when a predetermined time has arrived.

[0078] For example, after a predetermined time, the bridge member 23 of the electric opening / closing device 2 is first moved to the fully open position to engage with the engagement member 31, and then the bridge member 23 is moved in the closing direction to close the inner window 12. The closing process in the manual opening / closing mode may be performed in bad weather such as when there is strong wind and rain.

[0079] -Opening and closing control of an internal sliding window device- An example of the control flow in the electric drive mode of the inner sliding window device of this embodiment will be described with reference to the flow shown in FIG.

[0080] When the power is turned on, the internal sliding window device checks in step S101 whether the internal sliding window device is in automatic operation mode or manual operation mode. The user can switch the operation mode by selecting the mode selection button on the operation device 7.

[0081] (Autonomous driving mode) If the automatic operation mode is selected, the inner sliding window device proceeds to step S102 and checks whether the wind speed detected by the wind speed sensor 501 is equal to or greater than the threshold value a.

[0082] If the wind speed detected by the wind speed sensor 501 is equal to or less than the threshold value a, the inner sliding window device proceeds to step S103 and checks whether or not rain has been detected by the rainfall sensor 502. On the other hand, if the wind speed detected by the wind speed sensor 501 is equal to or greater than the threshold value a, the device proceeds to step S105.

[0083] If rainfall is not detected in step S103, the inwardly moving single sliding window device proceeds to step S104, executes a process to partially open the inner shoji 12 of the inwardly moving single sliding window 1, and then returns to step S101.

[0084] In step S105, the inner sliding window device executes the process of closing the inner sliding screen 12. The inner sliding window device starts timing at the same time as it executes the closing process of the inner sliding screen 12, and maintains the closed state until 30 minutes have passed, after which it returns to step S101 (step S106).

[0085] (Handheld operation mode) On the other hand, if the manual operation mode is selected, the inner sliding window device proceeds to step S112 and checks whether the wind speed detected by the wind speed sensor 501 is equal to or greater than the threshold value a.

[0086] If the wind speed detected by the wind speed sensor 501 is equal to or greater than the threshold value a, the inner sliding window device proceeds to step S117 and executes the process of closing the inner sliding screen 12. On the other hand, if the wind speed detected by the wind speed sensor 501 is equal to or lower than the threshold value a, the inner sliding window device proceeds to step S113 and checks the operation of the inner sliding window 1 selected by the user.

[0087] If the command selected by the user is to open the inner shutter 12, the inner sliding window device executes the full opening process of the inner shutter 12; if the selected command is to close the inner shutter 12, it executes the closing process of the inner shutter 12; if the selected command is to stop the inner shutter 12, it cancels the opening or closing process of the inner shutter 12 and returns to step S101.

[0088] In step S117, the inner sliding window that has performed the closing process of the inner shoji screen 12 starts timing at the same time as performing the process, and remains closed until 30 minutes have passed, after which it returns to step S101 (step S118). An example of the control flow in the electric drive mode of the inner sliding window device of this embodiment has been described above.

[0089] -Effects of the natural ventilation window system of the embodiment- As described above, the inwardly moving single sliding window of this embodiment can be easily switched between an electric opening / closing mode and a manual opening / closing mode, making it easy to use. Furthermore, even in manual opening / closing mode, the window can be automatically restored to the electric opening / closing mode, which helps prevent forgetting to close the window.

[0090] In addition, in the manual operation mode, when the wind speed is above a predetermined value or in bad weather such as rain, only the closing operation can be accepted, and the opening and stopping operations cannot be accepted.

[0091] Furthermore, in the above-described embodiment, the position of the bridge member 23 is detected by the protrusion 23c of the bridge member 23 abutting against each sensor 26, but in other embodiments, a protrusion may be provided on the left vertical frame 123 of the inner sash 12 or on the engaging member 31 instead of on the bridge member 23, and this protrusion may abut against each sensor 26. In this case, if the sensors 26 do not detect that the inner sash 12 has reached the target position (closed, partially open or fully open position) even when the electric opening and closing device 2 is rotated in a predetermined direction, it is desirable to configure the electric opening and closing device 2 to be reversed.

[0092] With this configuration, even if the engagement between the engaging member 31 and the bridge member 23 is manually disengaged and the inner shoji screen 12 is left in a manually open state, it is possible to detect that the inner shoji screen 12 has not reached the target position after rotating the electric opening and closing device 2 in the specified direction, and then by reversing the electric opening and closing device 2, the engagement between the engaging member 31 and the bridge member 23 can be automatically restored, and by rotating it in the specified direction again, the inner shoji screen 12 can be moved to the original target position. Therefore, even if there is a sudden change in the weather, the inner shoji screen 12 will not remain open, so damage caused by a sudden change in weather can be minimized.

[0093] The specific operation will be explained below. Assume that the operating lever 322 is manually operated to disengage the engaging member 31 from the bridge member 23, moving only the inner screen 12 slightly toward the fully open position, and then leaving it as it is. In this state, if the weather suddenly changes, the detector 5 detects this and the control unit 6 rotates the electric opening and closing device 2 in the specified direction to close the inner sliding window 1, causing the bridge member 23 to move rightward toward the bearing 25.

[0094] Because the engaging member 31 is not engaged with the bridge member 23, the inner screen 12 remains open even when the bridge member 23 moves to the right, but because the protrusions on the left stile 123 or the engaging member 31 do not abut against the closing detection sensor 26a, the control unit 6 attempts to continue rotating the electric opening and closing device 2 in the specified direction. Then, the bridge member 23 finally abuts against the bearing 25. At this time, the torque limiter 22a provided on the left side of the slide rail 22 cuts off the transmission of power when a rotational load exceeding a specified value is applied to the slide rail 22, so the bridge member 23 is not damaged.

[0095] If the closing detection sensor 26a does not output a closing signal even though the specified load continues to be applied to the electric opening / closing device 2, the control unit 6 determines that the bridge member 23 and the engaging member 31 are disengaged and the inner shoji screen 12 is not closed, and rotates the electric opening / closing device 2 in the reverse direction. The reversal of the electric opening / closing device 2 then causes the bridge member 23 to move leftward and engage with the engaging member 31. If the electric opening / closing device 2 continues to be reversed, the protrusion abuts the full-open detection sensor 26c, which detects that the inner shoji screen 12 is in the fully open position and outputs a full-open signal to the control unit 6. In bad weather, the electric opening / closing device 2 can be rotated in the specified direction to close the inner shoji screen 12. This allows the bridge member 23 and the engaging member 31 to be re-engaged even if the inner shoji screen 12 is left open by manual operation, thereby preventing damage such as flooding inside the room.

[0096] Although the above explanation has been given as an example of closing the inner shoji screen 12, it goes without saying that the engagement between the bridge member 23 and the engaging member 31 can be similarly restored even when the inner shoji screen 12 is partially or fully opened.

[0097] In addition, the detection device may be a dust sensor that detects the amount of dust indoors or a CO2 sensor that detects the CO2 concentration indoors, and the inner sliding window 1 may be controlled to open or close depending on the detection results of the detection device.

[0098] Furthermore, the detection of the opening degree of the inner screen 12 of the inner sliding window 1 is not limited to detection by a limit switch, but for example, the number of rotations of the slide rail can be detected by a detection means such as an encoder, and the position of the bridge member can be detected from the number of rotations. Accordingly, the partially open position of the inner shoji screen 12 may be set appropriately.

[0099] The configuration of the engaging members and engaged members provided on the frame body and the shoji screen is not particularly limited, and it is also possible to provide groove-shaped engaging members on the frame body and pin-shaped engaged members on the shoji screen. The type of window is not limited to an inward-moving single-sliding window, but may be either an opening / closing window with a shoji screen that slides left and right, or an opening / closing window with a shoji screen that slides up and down.

[0100] It goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
