Description

  The present invention relates to a window opening / closing device for an opening / closing window, such as a louver window, an awning window, a horizontal window, a vertical window, etc., an opening / closing window, and a method for refurbishing the opening / closing window.

Conventionally, opening and closing windows such as louver windows, awning windows, and window windows have been generally used to open and close the face material with a manual handle, but in recent years, electric windows that can open and close the face material electrically are also used. (For example, refer to Patent Document 1).
The electric window of Patent Document 1 controls the opening and closing of a louver by attaching a unit case containing a drive unit such as a motor and a control unit such as a limit switch to a vertical frame. In Patent Document 1, a motor or the like is incorporated into a dedicated unit case, and the unit case can be removed for repair or replacement.

JP 59-15735 A

However, in Patent Document 1, an elevating frame must be arranged in a vertical frame to which a unit case is attached, and an elevating operation member connected to the elevating frame has to be projected from the vertical frame into the unit case. Therefore, there is a problem that a window structure different from a sash window that is manually opened and closed is required, and electrical work and wiring are complicated. Furthermore, since a dedicated electric unit is required, there is a problem in that it cannot be applied to other windows such as a vertical window and is not versatile.
For this reason, there is also a problem that it is very difficult to change the window that is opened and closed manually by remodeling to an electric type.

  The object of the present invention is to provide a window that can be manually opened and closed and a window frame, etc., can be easily applied to various types of windows, and can be applied to various windows. An object of the present invention is to provide a window opening / closing device for an opening / closing window, an opening / closing window, and a method for refurbishing the opening / closing window that can be easily changed to an electric type.

  A window opening and closing device of the present invention is a window opening and closing device that opens and closes a face material by driving an opening and closing mechanism of the face material in a window including a window frame and a face material arranged in the window frame. A rotation transmission shaft having a detachable portion to which a manual handle or a chain operation pulley can be attached, and a connecting member connected to an opening / closing mechanism that is moved by rotation of the rotation transmission shaft to open and close the face material And an electric motor connected to the attaching / detaching portion of the rotation transmission shaft, and a control unit for controlling driving of the electric motor.

According to such a configuration, since the electric motor is connected to the attaching / detaching portion of the rotation transmission shaft to which the manual handle or the pulley can be attached, when the rotation transmission shaft is rotated by the chain hung on the manual handle or the pulley, The opening / closing mechanism for opening and closing the face material can be used as it is without any change. Therefore, an open / close window that is manually opened / closed can be easily and inexpensively converted into an electric open / close window by removing the manual handle and connecting the electric motor.
Even if the type of the main body is different because the type of the opening / closing window is different, it is only necessary to adjust the mounting position of the electric motor using a bracket or the like, and the electric motor and the control unit can be made common. That is, the torque for driving the main body of the operator handle that is operated by a manual handle or the like is a torque that can be manually operated, and is therefore almost constant regardless of the window type. Therefore, since the torque required to rotate the rotation transmission shaft to which the manual handle is attached by the electric motor is almost constant regardless of the window type, the electric motor and the control unit should be shared regardless of the window type. Can do. Therefore, the main body can be shared with the manually operated window, and the electric motor and the controller can be shared regardless of the window type, so it is highly versatile and can be opened and closed manually. The window can be easily changed to an electric type.
Furthermore, since the electric motor is attached to the part where the manual handle or the like was attached, if an outlet is provided on the wall or the like in the vicinity of the window frame, there is no need to route the wiring in the window frame. For this reason, the worker in charge of electrical work only needs to install an outlet near the window, and the worker in charge of installing the window can install it by simply plugging it into the outlet in addition to installing the window. . Therefore, when wiring in the window frame, electrical work and window installation work are mixed, making the work complicated. In the present invention, each work can be separated, so that work efficiency can be improved. . In addition, the electrical work can be performed simply by installing an outlet on a general wall, and it is not necessary to wire in the window frame, so the electrical work can be easily performed. Therefore, the construction cost can be greatly reduced.

Here, the rotation transmission shaft is constituted by a serration shaft having teeth formed on a peripheral surface, and an output shaft of the electric motor is connected to the rotation transmission shaft via a joint member fitted to the serration shaft. It is preferable.
A rotation transmission shaft in a normal operator handle is a serration shaft. Therefore, for example, a joint member that is formed in a substantially cylindrical shape and has teeth that fit into the serration shaft on the inner peripheral surface on one end side in the axial direction is fitted, and the electric motor is inserted into the joint member from the other end side. The rotation transmission shaft and the output shaft of the electric motor can be easily connected by simply inserting the output shaft and locking it with a screw or the like. In addition, a general electric motor having an output shaft can be used, and the cost can be reduced.
An electric motor with a general reduction gear may be used.

The present invention also includes a bracket that is attached to the window frame and supports the electric motor, and a plurality of brackets are prepared according to the type of the main body, and the bracket is selected according to the main body. Is preferably attached to the window frame together with the main body.
If the electric motor is attached to the window frame via a bracket, the electric motor can be firmly fixed. Also, the type of the main body of the operator handle is different, for example, even if the position of the electric motor is different because the position of the rotation transmission shaft with respect to the window frame is different, by changing only the bracket, the electric motor etc. Common things can be used and versatility can be improved.

Moreover, it is preferable that the said control part is attached to an electrical outlet, and is connected with the electric motor via wiring.
The control unit for controlling the drive of the electric motor may be formed integrally with the electric motor, but if it is separated as in the present invention, the size of the electric motor part attached to the opening / closing window part can be reduced, and the opening / closing can be performed. The design of the window can be improved and the usability of the window can be improved.
At this time, the control unit including the control unit may be attached to the outlet via the power cable, but it is preferable to form a plug in the control unit and attach the control unit directly to the outlet. In this way, the control unit can be attached to the wall simply by inserting the plug of the control unit into an outlet, and it is not necessary to fix the control unit to the wall with a screw or the like, so that the workability can be improved.

Moreover, it is preferable that the said control part is provided with the receiving part which receives the signal from a remote control, and can control the drive and stop of an electric motor by operation from a remote control.
If the control unit is equipped with a receiving unit and the drive of the electric motor can be controlled by remote control operation, for example, the opening and closing operation of the window provided at a high place can be easily performed like the opening and closing window provided in the atrium. Can do. In addition, the control unit and the receiving unit can be integrated into one unit, so that handling and construction workability during construction can be improved.

Further, the control unit may stop driving the electric motor when a current value flowing through the electric motor exceeds a preset threshold after a predetermined time has elapsed after starting the driving of the electric motor. preferable.
As a method for controlling the opening and closing of the window, it may be controlled by providing a limit switch that is turned on when the face material is closed or opened, or by providing a sensor that measures the rotation amount of the electric motor. However, a switch or sensor is required, which increases the cost, and when controlling with the amount of rotation, if a measurement error occurs, the problem is that the window cannot be completely closed or opened. is there.
On the other hand, when controlling with the electric current value of an electric motor like this invention, a limit switch etc. become unnecessary, and while being able to reduce cost, a face material can be opened and closed reliably. That is, when the face material is opened and closed using a link mechanism or the like, the movable angle range of the face material is limited to a certain range due to the face material coming into contact with the window frame or the movement limit of the link mechanism. Therefore, when the face material cannot be moved while the face material is driven to open and close by the electric motor, the load of the electric motor increases rapidly and becomes an overload state. In this overload state, the motor current increases rapidly, and can be easily detected by setting a predetermined threshold. Therefore, according to this invention, cost can be reduced and a face material can be opened and closed reliably.

The opening / closing window of the present invention includes a window frame, a face member disposed in the window frame, an opening / closing mechanism for opening / closing the face member, and the window opening / closing device for driving the opening / closing mechanism to open / close the face member. And.
According to such an opening / closing window, since the window opening / closing device described above is provided, the same effects as those of the window opening / closing device described above can be obtained. That is, even in the manually opened / closed window, it can be easily and inexpensively converted into an electrically operated window, and the main body can be shared with a manually operated window, and Since the electric motor and the control unit can be shared regardless of the window type, the versatility is high, and the window that is manually opened and closed can be more easily changed to the electric type.
Furthermore, since the electrical work and the window installation work can be separated, work efficiency can be improved. In addition, the electrical work can be performed simply by installing an outlet on a general wall, and it is not necessary to wire in the window frame, so the electrical work can be easily performed.

The refurbishing method for an opening / closing window of the present invention includes a window frame, a face member disposed in the window frame, an opening / closing mechanism for opening / closing the face member, and an operator for driving the opening / closing mechanism to open / close the face member. A revolving method for electrifying an opening / closing window provided with a handle, wherein the operator handle configured to have a main body portion and a manual handle is removed, and the rotation transmission shaft to which the manual handle is attached The output shaft of the electric motor is connected to the control unit, and a control unit for controlling the electric motor is connected to an outlet.
According to the present invention, an existing manually operated opening / closing window can be easily and inexpensively converted into an electric opening / closing window.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view of an awning window 10 as an opening / closing window according to the present embodiment as viewed from the indoor side, FIG. 2 is a cross-sectional view of the awning window 10, and FIG. 3 is a manual type and electric type operator handle part. FIG. 4 is an exploded perspective view, and FIG. 4 is a diagram showing a change in current depending on the control state of the electric motor.

The awning window 10 includes a window frame 14 in which an upper frame (not shown), a lower frame 12, and left and right vertical frames 13 are framed on four sides, and a plurality of awning windows 10 supported in an openable / closable manner inside the window frame 14 (this embodiment). Then, 4 sheets of shojis (face materials) 15 are provided.
The window frame 14 is fixed to a housing such as an outer wall of the building or the pillar 1.
The shoji 15, which is a face material, is configured by fitting a panel material, for example, a glass panel 19, into an interior in which an upper rod 16, a lower rod 17, and left and right vertical rods 18 are assembled on four sides. Note that a screen door 20 is appropriately provided on the indoor side of the shoji 15 so as to be opened and closed.

  An open / close mechanism 21 for opening and closing the shoji 15 is incorporated in the vertical frame 13 of the window frame 14. The opening / closing mechanism 21 has an interlocking rod disposed along the vertical frame 13 and capable of moving up and down, a support arm attached between the vertical frame 13 and the shoji 15, and the interlocking rod with a manual handle. Since it is the same as a conventional opening / closing mechanism that moves up and down to open and close the shoji 15, detailed description is omitted.

  As shown in FIG. 3, the main body 30 of the operator handle is screwed to the indoor surface of one vertical frame 13 using a mounting screw 31 as in the case of a manual awning window. In the present embodiment, the bracket 41 is also screwed with the mounting screw 31 together with the main body 30. Note that the attachment screw 31 is hidden by a cover member 30A attached to the main body 30 and prevents the appearance design from being deteriorated.

The main body 30 includes a rotation transmission shaft 32 and a connection arm 33 as a connection member that is swung with the rotation of the rotation transmission shaft 32. A gear incorporated in the main body 30 is appropriately provided between the rotation transmission shaft 32 and the connecting arm 33. That is, the main body 30 is the same as the main body of the operator handle when a conventional manual handle is used.
Therefore, the rotation transmission shaft 32 is a serration shaft, and as shown in FIG. 3, a conventionally used manual handle 35 is detachable. Therefore, the detachable portion to which the manual handle 35 can be attached is constituted by the serration shaft portion of the rotation transmission shaft 32.

An output shaft (motor shaft) 43 </ b> A of an electric motor 43 with a speed reducer is connected to the rotation transmission shaft 32 via a coupling (joint member) 42.
The coupling 42 is formed in a substantially cylindrical shape, and in the inner through hole portion, teeth that are fitted to teeth formed on the outer periphery of the rotation transmission shaft 32 are formed on the rotation transmission shaft 32 side. It is comprised so that it can join in the state stopped with respect to 32. FIG.
Further, the coupling 42 and the output shaft 43A are joined together by inserting the output shaft 43A into the coupling 42 and preventing the rotation with screws.
Therefore, when the electric motor 43 is driven, the rotational force is transmitted to the rotation transmission shaft 32 via the output shaft 43A and the coupling 42.

  The electric motor 43 is screwed to the bracket 41 and supported. That is, when the rotation transmission shaft 32 and the output shaft 43A are connected via the coupling 42, the shafts 32 and 43A are located on the same axis, and the dimension between the shafts 32 and 43A is the coupling. It is necessary to make the dimensions connectable via 42. For this reason, the electric motor 43 is disposed at a predetermined position by the bracket 41.

A motor case 45 that covers the electric motor 43 is detachably attached to the bracket 41. The power cord 43 </ b> B of the electric motor 43 is connected to a power cord 51 extended from the control unit 50 in the motor case 45.
The control unit 50 includes a plug that is plugged into an outlet 3 provided on a wall, a receiving unit that receives a signal (infrared ray or radio wave) from the remote control 60, a relay circuit that controls driving of the electric motor 43, and the like. . Therefore, in this embodiment, the control unit is configured by the control unit 50.

The remote controller 60 is provided with an open button that is pressed when the window is opened, a close button that is pressed when the window is closed, and a stop button that stops driving. The electric motor 43 is operated by the user pressing and operating these buttons. The drive can be controlled.
Accordingly, the window opening / closing device 5 of the present invention is constituted by the main body 30 of the operator handle, the bracket 41, the coupling 42, the electric motor 43, the motor case 45, and the control unit 50.

[Construction method during renovation]
Next, a procedure for remodeling an existing manual operation type awning window into an electric operation type awning window 10 in the present embodiment will be described.
First, the manual handle 35 of the existing awning window is removed from the rotation transmission shaft 32. Further, the connecting arm 33 is removed from the opening / closing mechanism 21, and the mounting screw 31 is removed to remove the main body 30 of the operator handle from the vertical frame 13.
Next, the bracket 41 is aligned with the main body 30, the coupling 42 is attached to the rotation transmission shaft 32, and the output shaft 43 </ b> A of the electric motor 43 is inserted and attached to the coupling 42. Further, the electric motor 43 is screwed to the bracket 41.
Next, the bracket 41 and the main body 30 are attached to the vertical frame 13 with the attachment screws 31. Then, the connecting arm 33 is connected to the opening / closing mechanism 21.

Further, the control unit 50 and the electric motor 43 are connected (connected), and the control unit 50 is inserted into the outlet 3 and attached. In addition, when the outlet 3 is not provided, it is only necessary to separately install the outlet 3 on the wall by an electrician.
With the above construction, the manually operated awning window can be changed to the electrically operated awning window 10.

[Construction method for new installation]
Note that when the electric operation type awning window 10 is newly installed, the procedure for removing the manual handle 35 is not required, but the procedure for remodeling is different, but the other procedures may be performed in the same manner.

[Opening / closing control of awning window]
Next, opening / closing control in the awning window 10 of the present embodiment will be described.
When the open button of the remote controller 60 is pressed, the electric motor 43 is driven to rotate the rotation transmission shaft 32 in the direction of opening the window with the manual handle 35. Then, similarly to the case where the manual handle 35 is turned, the opening / closing mechanism 21 operates to open the respective shoji 15. In this case, since the load, that is, the torque for rotating the rotation transmission shaft 32 is substantially constant, the current value of the electric power supplied to the electric motor 43 is also substantially constant.
When the shoji 15 is fully opened and cannot be opened any more, the electric motor 43 enters an overload state, and the current value increases rapidly. Therefore, as shown in FIG. 4, when the current value of the electric motor 43 continuously exceeds a predetermined threshold value (threshold value) S for a predetermined time t1, the control unit 50 stops the electric motor 43. To do. Since no electric power is supplied while the electric motor 43 is stopped, no current flows.

When the user presses the close button to close the awning window 10, the electric motor 43 is reversely rotated, and the rotation transmission shaft 32 is rotated by the manual handle 35 in the direction of closing the window. Then, similarly to the case where the manual handle 35 is turned, the opening / closing mechanism 21 is operated to close each of the shojis 15.
Here, when the electric motor 43 in a stopped state is reversed, the biting (friction resistance) of the gear becomes large, the electric motor 43 is temporarily overloaded, and the current may exceed the threshold value S. There is. For this reason, the control unit 50 of the present embodiment stops the comparison control between the current value and the threshold value S for a predetermined time t2 from when the drive of the electric motor 43 is instructed (when the button is pressed). Alternatively, by changing the threshold value itself to a larger value S2, even if an overload state due to gear biting occurs immediately after the start of driving of the electric motor 43, the electric motor 43 is continuously driven without being stopped. So that it is controlled. The current value that temporarily increases at the start of driving becomes substantially constant as the rotation transmission shaft 32 is driven by the electric motor 43.

  When the electric motor 43 is reversed by pressing the close button and the shoji 15 is closed and fully closed, the electric motor 43 is overloaded and the current value increases rapidly. Therefore, as shown in FIG. 4, when the current value of the electric motor 43 exceeds the predetermined threshold S for a predetermined time t1, as in the case where the shoji 15 is fully opened, the control unit 50 The electric motor 43 is stopped.

When the open button is pressed again, the shoji 15 is opened by the electric motor 43. Even when the open button is pressed, the control by the threshold value S is not performed for the predetermined time t2, and the drive of the electric motor 43 is continued. When the current exceeds the threshold value S for a predetermined time t1 after the elapse of the predetermined time t2, the control unit 50 stops the electric motor 43.
The opening / closing control of the shoji 15 is performed by repeating the above control. When the shoji 15 is not fully opened but is opened by a predetermined angle, the electric motor 43 may be stopped by pressing a stop button when the shoji 15 is opened to a desired angle.

According to this embodiment, there are the following effects.
(1) Since the electric operation type awning window 10 can be configured by removing the manual handle 35 of the manual operation type awning window and attaching the electric motor 43, the sash body such as the window frame 14, the shoji 15 and the opening / closing mechanism 21 is A general one operated by the manual handle 35 can be used as it is. Therefore, as in the conventional case, since a dedicated electric unit is attached to the vertical frame, the versatility is high and the cost can be reduced as compared with the case where special processing is applied to the vertical frame.
Moreover, since it is only necessary to remove the manual handle 35 and attach the electric motor 43, the change from the manual operation type to the electric operation type can be performed very easily. Therefore, it is possible to change to an electric type easily and at low cost when dealing with after-sales service or renovation, and it is possible to flexibly respond to user requests.
Furthermore, it is possible to easily return to the manual operation type simply by removing the electric motor 43 and the like and attaching the manual handle 35. For example, it is easy to change the electric type only for a certain period at the request of a resident in a rental house or the like. It can be carried out.

(2) Since the electric motor 43 is provided in place of the manual handle 35 and driven, various types of doors that are opened and closed not only by the awning window 10 but also by operating a handle such as a glass louver window, a side-out window, and a vertical-out window Applicable to open / close windows. That is, in various opening / closing windows, the size of the main body portion of the operator handle, the inclination direction of the rotation transmission shaft 32, and the like may differ due to storage and design. For this reason, for example, when the indoor surface of the window frame 14 to which the bracket 41 is attached is used as a reference, the positions of the electric motors 43 are different. Even in such a case, if only the bracket 41 is prepared, the coupling 42, the electric motor 43, and the control unit 50 can be used in common with various opening and closing windows, and in this respect, versatility can be improved. The number of parts can be reduced and the cost can be reduced.

(3) Since there is no need to wire the power cord into the window frame as in the past, the electrical contractor only has to install the outlet 3, and the other work should be performed by the sash window installer. Can do.
Therefore, electrical work and sash construction work can be separated, process management of construction work becomes easy, construction workability can be improved, and construction cost can be reduced.
In particular, the electrical work only needs to be done by the electrical contractor, such as installing the outlet 3 on the wall, and it is not necessary to carry out the special work of wiring into the window frame. Can be performed efficiently and at low cost.
Further, if the sash contractor performs the installation work of the bracket 41 and the electric motor 43 in addition to the normal manual operation type opening / closing window construction, the control unit 50 need only be inserted into the outlet 3 thereafter. The construction workability is not lowered, and the construction work can be performed with the same workability as the conventional one.

(4) With conventional electric operation type opening and closing windows, the dedicated unit must be attached to the dedicated window frame, the controller box must be embedded in the wall, and the wiring connecting this controller box and the dedicated unit must be embedded in the wall. In addition, the number of work processes is increased, and dedicated parts are required, so the cost is high. For this reason, FIX windows that cannot be opened and closed are often employed at high positions such as the atrium space.
On the other hand, the awning window 10 of the present embodiment can reduce the cost of parts because it can divert the manual operation type awning window, and can also reduce the work cost because the wiring work in the wall is not necessary. Compared to the electric operation type, it can be provided at a lower cost. Therefore, it is possible to install an opening / closing window in a portion where installation is difficult in terms of cost, and in addition to improving daylighting, the ventilation function can be improved and an excellent living space can be formed.

(5) Since the output shaft 43A of the electric motor 43 and the rotation transmission shaft 32 are coupled using the coupling 42, the normal electric motor 43 can be used. Further, since the coupling 42 is configured to be fitted to the serration shaft portion of the rotation transmission shaft 32, the coupling 42 can be connected simply by being inserted into the rotation transmission shaft 32, and the connection work can be easily performed.

(6) Since the electric motor 43 and the control unit 50 are separated, the size of the parts attached to the window frame 14 of the awning window 10 in the window opening and closing device 5 can be reduced. Therefore, the design of the awning window 10 can be improved, the window opening / closing device 5 is less likely to become an obstacle when using the window, and the usability of the window can be improved.
In addition, since the plug is formed in the control unit 50 and the control unit 50 is directly inserted into the outlet 3, it is not necessary to separately fix the control unit 50 to the wall using screws or the like, and the workability can be improved. Further, when the control unit 50 is formed with a light receiving portion that receives a signal from the remote controller 60, the control unit 50 is placed on the wall surface by attaching the control unit 50 to the outlet 3, and the signal from the remote controller 60 is received. It is possible to make the awning window 10 easy to operate and easy to operate. In addition, since the drive of the electric motor 43 can be controlled by a remote control operation, an opening / closing operation of a window provided at a high place can be easily performed. In addition, the control unit and the receiving unit can be integrated into one unit, so that handling and construction workability during construction can be improved.

(7) Since the control unit 50 detects the overload state based on the current value of the electric motor 43 and performs stop control of the electric motor 43, the limit switch and the rotation amount detection sensor can be dispensed with and the cost can be reduced. Since it can be reduced and an overload condition is detected, it can be detected that the window is fully opened or fully closed, and can be opened and closed reliably.
Further, after the electric motor 43 starts to be driven, when the current value flowing through the electric motor 43 exceeds a preset threshold value S after a predetermined time t2, the electric motor 43 is stopped. Therefore, even if the threshold value S is exceeded within the predetermined time t2, the driving of the electric motor 43 can be continued. For this reason, even if it temporarily becomes an overload state due to the biting of the gear or the like, the drive of the electric motor 43 can be continued and the shoji 15 can be opened and closed reliably.

Note that the present invention is not limited to the above-described embodiments, and includes other configurations that can achieve the object of the present invention, and includes the following modifications and the like.
For example, the window opening and closing device 5 may be provided with a mechanism that can open and close the awning window 10 during a power failure. For example, an emergency battery unit incorporating a dry battery or the like may be prepared separately, connected to the control unit 50 and supplied with power, so that the window 10 can be temporarily opened and closed even during a power failure.
Alternatively, the outer peripheral surface of the coupling 42 may be configured to have a hexagonal cross section so that the window 10 can be opened and closed by rotating the coupling 42 and the rotation transmission shaft 32 with a dedicated wrench.
Further, the bracket 41 is configured to be slidable and the like, and the electric motor 43 and the coupling 42 are removed from the rotation transmission shaft 32, and the manual handle 35 is attached to the rotation transmission shaft 32 so that the window 10 can be manually opened and closed. May be.

  The control unit 50 is not limited to detecting an overload state with a current value, and may control based on other data such as a voltage value. In addition, a limit switch that is turned on when the shoji 15 is fully closed or fully open, a sensor that detects the amount of rotation of the electric motor 43, and the like may be provided to control the driving of the shoji 15.

  The control unit 50 is not limited to being operated by the dedicated remote controller 60, and may be controlled by a remote controller of another electrical product such as a mobile phone or a television. In particular, in the present invention, it is only necessary to be able to instruct the three states of open, closed, and stop, so that it is possible to easily emit a mobile phone or the like by emitting a predetermined signal to a mobile phone or other remote controller. Available.

Further, by providing an operation button in the control unit 50, the control unit 50 may be controlled by a button operation. Further, it may be controlled by both the operation button of the control unit 50 and the remote controller 60.
The control unit 50 is not limited to driving the electric motor 43 based on a button operation. For example, the control unit 50 opens and closes the shoji 15 based on a signal from a gas sensor, a fire sensor (a sensor for detecting smoke or heat), or the like. May be. In this case, when the sensor detects a situation requiring ventilation, the shoji 15 can be automatically opened to perform ventilation.

The control unit 50 is not limited to the type directly plugged into the outlet 3, but may be plugged into the outlet 3 via a power cord.
Moreover, in the said embodiment, although the electric motor 43 and the control unit 50 were made into a different body, you may comprise integrally. However, as in the above-described embodiment, a separate body has an advantage that a portion attached to the window frame 14 can be made compact.

Only one type of bracket 41 may be prepared and used in combination with various windows, or a plurality of types of brackets 41 may be prepared and used for each type of window. For example, in various windows, when the main body 30 of the operator handle using the manual handle 35 is common, only one type of bracket 41 may be prepared, and the types of parts can be reduced.
Further, even when the type of the main body 30 is different, for example, an attachment hole through which the attachment screw 31 for attaching the bracket 41 to the window frame is inserted or a hole to which the electric motor 43 is attached is formed into a long hole or a plurality of holes are formed. Thus, the difference in the main body 30 may be absorbed, and one type of bracket 41 may be used. Also, the bracket 41 may be of one type by absorbing the difference in the type of the main body 30 by using a universal joint for the connection between the rotation transmission shaft 32 and the output shaft 43A.
Similarly, even when a plurality of types of brackets 41 are prepared, the bracket 41 is not limited to the case of preparing each type of window, and the bracket 41 can be made common to a plurality of types of windows by using a long hole as described above. By doing so, the types of brackets 41 may be reduced compared to the types of window types.

In the embodiment, the electric motor 43 is directly fixed to the bracket 41, but may be fixed via a spacer member or the like. With this configuration, when the main body 30 is different due to the difference in each window type and the arrangement position of the electric motor 43 is different, if the difference is absorbed by the spacer member, the types of brackets 41 are reduced. There are advantages you can do.
Moreover, in the said embodiment, although the bracket 41 which supports the electric motor 43 was attached to the window frame 14 with the main-body part 30, you may attach to housings, such as the window frame 14 and the pillar 1, separately from the main-body part 30. . That is, in the present invention, the main body 30 that needs to be connected to the opening / closing mechanism 21 may be attached to the window frame 14, and the bracket 41 may be attached to the window frame 14 or may be attached to the housing. However, the attachment to the window frame 14 together with the main body 30 as in the above-described embodiment has the advantage that the attachment structure can be simplified and the attachment structure can be simplified.

The connection between the rotation transmission shaft 32 and the electric motor 43 is not limited to that using the coupling 42. For example, when the rotation transmission shaft 32 and the output shaft 43A are not coaxially arranged, the rotation transmission shaft 32 and the output shaft 43A may be connected using a universal joint or the like.
Further, when the output shaft 43A of the electric motor 43 is configured so that the rotation transmission shaft 32 can be inserted similarly to the manual handle 35, the rotation transmission shaft 32 and the output shaft 43A may be directly connected.
In short, it is only necessary that the rotation of the electric motor 43 can be transmitted to the rotation transmission shaft 32.

The window to which the window opening / closing device 5 of the present invention is applied is not limited to the awning window 10 but can be applied to various opening / closing windows provided with an operator handle, such as a glass louver window, a side ridge window, and a vertical window.
Furthermore, the opening / closing window is not limited to the one provided with the manual handle 35, and a pulley is attached to the rotation transmission shaft, and the window that has been manually opened / closed by operating the chain hung on the pulley is motorized. It can also be applied to In this case, the electric motor 43 may be attached by removing the pulley from the rotation transmission shaft.

Further, the window opening and closing device 5 of the present invention may be attached to and controlled by a plurality of windows. In this case, the control unit 50 and the remote controller 60 are each provided with a switch (signal mode selector switch) capable of switching the type of signal to be exchanged, and the remote controller 60 is set to a mode in which the control unit 50 of the window to be operated is set. You may switch and control.
Furthermore, for example, it may be configured such that a control signal can be transmitted via a power line, and each control unit 50 can be centrally controlled by home automation or the like.

Furthermore, the presence / absence of the motor case 45, the type of the electric motor 43, and the like may be set as appropriate in implementation.
Moreover, in the said embodiment, although the electric motor 43 was driven using the commercial power from the outlet 3, for example, a battery (primary battery) or a battery (secondary battery) is built in the control unit 50, You may make it drive with the electric power. In this case, for example, a solar cell may be provided on a window or a wall, and the generated power may be stored and used.
