Description

  The present invention relates to a state display device applied to a window device having a window frame and a shoji that is displaced relative to the window frame.

  For example, in the state display device described in Patent Document 1, a detection unit that detects that the window device is in a closed state is provided, and when the closed state is detected, a display unit that uses an electrical signal such as a lamp is provided. After turning on for a predetermined time, the display unit is turned off.

Japanese Patent Laid-Open No. 9-41796

  However, in the device described in Patent Document 1, the display unit is turned on when the closed state is detected, and the display unit is turned off when a predetermined time has elapsed after the lighting. For this reason, after the lights are turned off, it is impossible to display (notify) the operator whether or not the window device is in the closed state.

  In view of the above points, the present invention aims to display to the operator whether or not the window device is in the closed state even when time has elapsed since the closed state was detected. .

  In order to achieve the above object, the present invention is a state display device that displays the state of the window device (1), and a first detection unit that detects whether the window device (1) is in a closed state ( 19) and the display body (17) indicating that the display body is displaced between the first position and the second position and is closed when the first position is located, and the display body (17) is moved to the first position. When the closed state is detected by the electric actuator (21) that is displaced between the first position and the second position, and the first detector (19), the actuator (21) is energized to display the display body (17). And a first energization control unit (25A, 27) for stopping the energization after displacing to the first position.

  Thus, in the present invention, the position of the display body (17) is maintained at the first position even after the actuator (21) is stopped. Therefore, even if a long time has elapsed since the closed state was detected, it is possible to display to the operator whether or not the window device is in the closed state.

  Incidentally, in the present invention, the power source for driving the actuator (21) may be any of a power storage member such as a battery, a commercial power source, and a household power source. And especially when it is set as the structure which drives an actuator (21) by using an electrical storage member as a power supply, power consumption can be reduced from the idea of patent document 1. FIG.

  That is, in the device described in Patent Document 1, in order to continue displaying that the window device (1) is in the closed state, it is necessary to continue supplying power to the display unit. On the other hand, in the present invention, even after the actuator (21) is stopped, the position of the display body (17) is maintained at the first position. Therefore, it is necessary to continue supplying power to the actuator (21). There is no.

Therefore, in the present invention, when the actuator (21) is driven using the power storage member as a power source, the power consumption can be reduced as compared with the device described in Patent Document 1.

  An “invention embodiment” described below shows an example of an embodiment. That is, the device identification items described in the claims of the utility model registration are not limited to the specific means and structures shown in the following embodiments.

  In this embodiment, the window device 1 according to the present invention is applied to a smoke exhaust window. As shown in FIG. 1, the smoke exhaust window is a window device 1 having a window frame 3 and a shoji 5 that is swingably assembled to the window frame 3.

  Incidentally, the window apparatus 1 shown in FIG. 1 is an “externally falling smoke exhaust window”. And the said window apparatus 1 has a hinge mechanism (not shown) in the lower part of the window frame 3, and rocks and displaces so that the shoji 5 may fall outside the building (not shown). The hinge mechanism is a component that connects the window frame 3 and the shoji 5 so as to be swingable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
1. Window Device As shown in FIG. 1, the window frame 3 and the shoji 5 of the window device 1 according to the present embodiment are configured in a rectangular frame shape made of a light metal such as aluminum. The window frame 3 is fixed to the opening edge of the building by fastening means such as screws. A plate-like member such as a glass plate is assembled to the frame of the shoji 5.

  For this reason, when the window apparatus 1 is closed, the opening of the building is closed. On the other hand, when the window device 1 is opened (the state shown in FIG. 1), the shoji 5 is oscillated and displaced with respect to the window frame 3, and the opening of the building is opened.

  The window device 1 is provided with at least one stay damper 7 that causes the shoji 5 to act on the shoji 5 so that the shoji 5 is separated from the window frame 3 (hereinafter referred to as “separating force”). The stay damper 7 includes a cylindrical cylinder and a rod that protrudes and protrudes from the cylinder.

  A high-pressure gas that generates a separating force is sealed in the cylinder. One end side of the stay damper 7 in the longitudinal direction is rotatably connected to the window frame 3. On the other hand, the other end in the longitudinal direction of the stay damper 7 is rotatably connected to the shoji 5. For this reason, the stay damper 7 always applies a separation force to the shoji 5.

  The auxiliary opening machine 9 applies the separating force to the shoji 5 when the tilt angle of the shoji 5 is small and the separating force of the stay damper 7 is small. The tilt angle of the shoji 5 refers to the swing angle between the shoji 5 and the window frame 3. That is, the falling angle of the shoji 5 when the window device 1 is closed is 0 degree. When the shoji 5 swings and the window device 1 opens, the tilt angle of the shoji 5 increases accordingly.

  The auxiliary opening machine 9 includes a swing arm 9A and an elastic member such as a torsion coil spring (not shown). And the torsion coil spring is comprised so that the deformation amount may become large, so that the fall angle of the shoji 5 becomes small. For this reason, the auxiliary opening machine 9 applies a larger separating force to the shoji 5 as the tilt angle of the shoji 5 is smaller.

2. Handle Box The handle box 10 is an operator for operating the window device 1 as shown in FIG. That is, as shown in FIG. 2, the handle box 10 has a winding mechanism 13 for winding the wire 5 </ b> A (see FIG. 1) connected to the shoji 5, a storage box 11 for storing the winding mechanism 13, and the like. ing.

  As shown in FIG. 3, the winding mechanism 13 includes a winding drum (not shown) that winds the wire 5 </ b> A, a ratchet mechanism 15 that controls the rotatable direction of the winding drum, and the like. The ratchet mechanism 15 controls the direction in which the take-up drum can rotate in accordance with the operation state of the release button 10B and take-up handle 10C described later.

  The release button 10B and the take-up handle 10C are provided on the front cover 10A of the handle box 10 as shown in FIG. Note that the front cover 10 </ b> A is a lid that is positioned in front of the handle box 10 and closes the front side of the storage box 11.

  The release button 10B is an operation unit for enabling the winding drum to rotate in the direction of the arrow shown in FIG. When the release button 10B is pressed, the winding drum can be rotated in the direction of the arrow shown in FIG. 4, that is, the shoji 5 can be opened. Therefore, when the release button 10B is pressed, the window device 1 is opened by the separating force of the stay damper 7 or the like.

  The winding handle 10C is an operation unit that rotates the winding drum in a direction in which the wire 5A is wound. The winding handle 10C is rotatably connected to the front cover 10A at the lower end side of the winding handle 10C (rough hatched portion in FIG. 5), and the winding handle 10C is swung with respect to the front cover 10A. A connecting portion 10D that can be provided is provided.

  When the release button 10B is pressed while the winding handle 10C is housed in the front cover 10A, the winding handle 10C falls to the front side and can be rotated. The connecting portion 10D is connected to the winding drum via a one-way clutch (not shown).

  The one-way clutch blocks transmission of rotational force from the winding drum to the winding handle 10C, and transmits rotational force from the winding handle 10C to the winding drum. For this reason, the winding handle 10C does not rotate when the wire 5A wound around the winding drum is opened, that is, when the winding drum rotates in the direction of the arrow shown in FIG.

  On the other hand, when the winding handle 10C rotates in the direction of winding the wire 5A, the ratchet mechanism 15 allows the winding drum to rotate in the direction of winding the wire 5A, as shown by the arrow in FIG. The rotation of the winding drum in the direction opposite to the arrow in FIG. Note that the winding handle 10C cannot be rotated in the direction opposite to the direction in which the wire 5A is wound.

  In the present embodiment, the main part of the status display device according to the present invention is incorporated in the handle box 10. The state display device displays that at least the window device 1 is in the closed state. Hereinafter, the state shown in FIG. 4 is referred to as a state where the ratchet mechanism 15 can be opened. Further, the state shown in FIG. 5 is said to be in a state where the ratchet mechanism 15 can be wound.

2.2 Configuration of Status Display Device On the back side of the front cover 10A, as shown in FIG. 6 (a), a display body 17 for indicating the closed state, and an electric actuator for displacing the display body 17 21 and a power source 21A for supplying electric power to the actuator 21 are provided. The power source 21A according to the present embodiment is a power storage unit such as a primary battery.

  Moreover, as shown in FIG. 1, the 1st detection part 19 which detects whether the window apparatus 1 is a closed state is provided in at least one among the window frame 3 and the shoji 5. FIG. The first detection unit 19 according to the present embodiment is a non-contact proximity sensor including a movable unit 19A provided on the shoji 5 and a fixed unit 19B provided on the window frame 3.

  As shown in FIG. 6B, the display body 17 is a columnar or cylindrical member, and is rotationally displaced between the first position and the second position. And when the display body 17 is located in a 1st position, it shows that the window apparatus 1 is a closed state.

  In the present embodiment, the outer peripheral surface of the display body 17 is divided into at least two areas in the circumferential direction, and one of the two divided areas is different from the other area. It has become.

  When the operator can visually recognize the one area through the viewing opening 10E (hereinafter referred to as the viewing window 10E) provided in the front cover 10A, the “display 17 is in the first position”. "It is located." In addition, when the operator can visually recognize the other area through the viewing window 10E, it is said that “the display body 17 is located at the second position”.

  Further, “different in form” refers to a state in which an operator can identify the two divided areas by at least one of color, pattern, and shape being different. Incidentally, in this embodiment, the color is different between one region and the other region.

  As shown in FIG. 6A, the actuator 21 supports the display body 17 and rotationally displaces the display body 17 between the first position and the second position. The actuator 21 according to the present embodiment is a DC electric motor that rotates the display body 17 by receiving power from the power source 21A. Therefore, hereinafter, the actuator 21 is also referred to as an electric motor 21.

  The support member 23 is a member that fixes the electric motor 21 to the front cover 10A. The support member 23 is provided with a first switch portion 25A that opens and closes a first electric circuit C1 described later. The first electric circuit C1 is an electric circuit that supplies electric power to the electric motor 21, as shown in FIG.

  Further, the first switch portion 25A is mechanically opened and closed by a switching cam 27 as shown in FIG. The switching cam 27 rotates integrally with the rotating shaft 21 </ b> B of the electric motor 21. For this reason, when the switching cam 27 rotates mechanically in synchronism with the rotation of the electric motor 21 and the rotation angle reaches a preset rotation angle, the first switch portion 25A is activated and the first electric unit 21 is operated. Circuit C1 is opened.

  The “preset rotation angle” is, for example, an angle obtained by dividing 360 degrees by the number of regions provided in the display body 17. In this embodiment, since the number of regions is 2, the “preset rotation angle” is 180 degrees.

  Moreover, in this embodiment, as shown in FIG. 2, the 2nd detection part 29 which detects whether the window apparatus 1 is an open state is provided. Then, as shown in FIGS. 3 and 4, the second detection unit 29 is based on the state of the ratchet mechanism 15, that is, whether or not the release button 10 </ b> B is pressed or whether the winding handle 10 </ b> C is operated. It is detected whether it is in an open state.

  That is, the second detection unit 29 according to the present embodiment is configured by a limit switch that opens and closes an electric circuit according to a contact state with the cam 31. When the ratchet mechanism 15 becomes openable, the cam 31 is displaced to a position in contact with the second detector 29 as shown in FIG.

  On the other hand, when the ratchet mechanism 15 can be wound, the cam 31 is displaced to a position separated from the second detection unit 29 as shown in FIG. That is, when the release button 10B is pressed, it is detected that the window device 1 is in an open state by contacting the cam 31 and the second detection unit 29.

2.3 Energization Control to Electric Motor FIG. 8 is an electric circuit diagram showing an energization control unit that controls energization to the electric motor 21. The electric circuit for energizing the electric motor 21 includes a first electric circuit C1 having a first detection unit 19, a second electric circuit C2 having a second detection unit 29, and the like.

  A first detection unit 19 and a first switch unit 25A are connected in series to the first electric circuit C1. For this reason, only when both the 1st detection part 19 and the 1st switch part 25A close, an electric current flows into the 1st electric circuit C1, and the electric motor 21 rotates.

Similarly, a second detection unit 29 and a second switch unit 25B are connected in series to the second electric circuit C2. For this reason, only when the 2nd detection part 29 and the 2nd switch part 25B close, an electric current flows into the 2nd electric circuit C2, and the electric motor 21 rotates. The second switch unit 25B is means for closing the electric circuit for a preset time. Also, as the “preset time”, the first switch unit 25A is switched from the open state to the closed state. This is the time required for the cam 27 to rotate. Therefore, when the second switch portion 25B is opened, the first switch portion 25A is in a closed state.

  The second switch unit 25B according to the present embodiment has an electrical resistance R and a capacitor C arranged in parallel, and the above “preset time” is set by the capacitance of the capacitor C. Is done.

  The electric motor 21 rotates only in one direction as shown in FIG. For this reason, every time the electric motor 21 rotates 180 degrees, the case where the display body 17 is in the first position and the case where the display body 17 is in the second position are alternately repeated.

2.4 Operation of Status Display Device When the release button 10B is pressed and the window device 1 starts to open, a current flows through the second electric circuit C2 and the electric motor 21 rotates, so that the display body 17 and the switching cam 27 rotate. To do.

  When the display body 17 is positioned at the second position and the window device 1 is in the open state is displayed through the viewing window 10E, and when the switching cam 27 rotates until the first switch portion 25A is closed, 2 The switch 25B is opened and the electric motor 21 is stopped.

  Further, when the winding handle 10C is operated in a state where the window device 1 is opened, the window device 1 is closed. And when the closed state of the window apparatus 1 is detected by the 1st detection part 19, since the 1st detection part 19 will be in the closed state, since an electric current flows into the 1st electric circuit C1 and the electric motor 21 rotates. The display body 17 and the switching cam 27 rotate.

  When the display body 17 is positioned at the first position and the window device 1 is in the closed state is displayed through the viewing window 10E, the switching cam 27 is rotated and the first switch 25A is opened. The motor 21 stops. Accordingly, the display body 17 remains in the first position.

3. Characteristics of the status display device according to the present embodiment In the present embodiment, the position of the display body 17 is maintained at the first position even after the actuator 21 is stopped. Therefore, even if a long time has elapsed since the closed state was detected, it is possible to display to the operator whether or not the window device 1 is in the closed state.

  In the present embodiment, even after the actuator 21 is stopped, the position of the display body 17 is maintained at the first position, so that it is not necessary to continue supplying power to the actuator 21. Therefore, in this embodiment, the power consumption of the power source 21A can be reduced.

  In the present embodiment, whether or not the display body 17 is positioned at the first position is determined by the rotation angle of the switching cam 27, that is, the actual position of the display body 17. On the other hand, whether or not the display body 17 is positioned at the second position is determined based on the elapsed time after the start of energization.

  For this reason, even if there is a difference between the rotation angle at which the display body 17 is actually rotated and the energization time, whether or not the display body 17 is positioned at the first position depends on the position of the actual display body 17. It is determined based on. Therefore, in the present embodiment, it is possible to prevent the “deviation between the rotation angle and the energization time” from becoming excessively large, and thus it is possible to reliably display that the window device 1 is in the closed state.

  That is, as shown in FIG. 9, the second switch portion 25B is disposed on the opposite side of the first switch portion 25A across the switching cam 27, that is, at a position shifted by approximately 180 degrees with respect to the first switch portion 25A. ing.

  And as shown in FIG. 10, the 2nd switch part 25B and the 2nd switch part 25B are connected to the 2nd electric circuit C2 in series. Therefore, as in the first embodiment, when the release button 10B is pressed and the window device 1 starts to open, a current flows through the second electric circuit C2 and the electric motor 21 rotates. Rotates.

  When the display body 17 is positioned at the second position and the window device 1 is in the open state is displayed through the viewing window 10E, and when the switching cam 27 rotates until the first switch portion 25A is closed, 2 The switch 25B is opened and the electric motor 21 is stopped.

  Further, when the winding handle 10C is operated in a state where the window device 1 is opened, the window device 1 is closed. And when the closed state of the window apparatus 1 is detected by the 1st detection part 19, since the 1st detection part 19 will be in the closed state, since an electric current flows into the 1st electric circuit C1 and the electric motor 21 rotates. The display body 17 and the switching cam 27 rotate.

  Then, the display body 17 is positioned at the first position, the fact that the window device 1 is closed is displayed through the viewing window 10E, the switching cam 27 is rotated, the second switch portion 25B is closed, and the first The electric motor 21 stops when the 1 switch unit 25A is opened. Accordingly, the display body 17 remains in the first position.
