BACKGROUND OF THE INVENTION
The present invention relates to a remote window closing confirmation device for confirming the closing of a window, which is used for a window device that applies tension to the wire by winding the wire and closes the window with the tension applied to the wire. Is.
[0002]
[Prior art]
2. Description of the Related Art A window device that closes a window by remotely operating a window farther than the user, such as a high window, is known. This window device applies a tension to the window by winding the wire when closing the window, and closes the window by this tension. As a method of winding the wire, a manual winding lever is rotated to rotate the wire. There are a manual type that winds the wire and an electric type that winds the wire by the rotational force of the electric motor. Since the electric type uses an electric motor or the like, there is a problem that the cost is increased, and a power source is required. Therefore, a simple manual type is often used because it cannot be used for a part without a power source.
[0003]
Note that the manual window device confirms that the window is closed by the increase in the operating force when the winding lever is turned when the window is closed.
[0004]
[Problems to be solved by the invention]
In manual window devices, the operator's operating force determines whether or not the window is closed, so some operators may mistakenly assume that the window is completely closed even if the window is not completely closed. Was the cause of damage entering the building.
[0005]
Therefore, a remote window closing confirmation device shown in FIG. 7 was developed (not a well-known technique). The remote window closing confirmation device shown in this figure includes a tension receiving portion J2 that can be changed by receiving the tension of the wire J1, and two elastic bodies J3 that pull the tension receiving portion J2 against the tension. When the window closes and the tension increases, the tension receiving part J2 overcomes the tension of the two elastic bodies J3 and changes, and the closing position of the pointer J4 provided on the tension receiving part J2 confirms the closing of the window It is.
[0006]
This remote window closing confirmation device is excellent in that it can be confirmed that the window is closed. However, the wire J1 is drawn into one side by the tension receiving portion J2, and two elastic bodies J3 are further connected to the tension receiving portion J2. As the remote window closing confirmation device is large in size, the remote window closing confirmation device has a problem. In addition, due to this increase in size, it has not been possible to meet the demand for storing the remote window closing confirmation device in the handle box for winding the wire.
[0007]
OBJECT OF THE INVENTION
The present invention has been made in view of the above circumstances, and an object thereof is to provide a remote window closing confirmation device that can confirm that the window is closed and can be downsized.
[0008]
[Means for Solving the Problems]
The remote window closing confirmation device of the present invention employs the following technical means.
[Means of Claim 1]
Remote window closing confirmation device
A frame attached to the building and having an opening on the inside;
A window that is supported to be displaceable with respect to the frame body, and that opens and closes the opening by moving,
A wire that provides a transition force in a direction to close the opening with respect to the window by being applied with tension;
By winding this wire, it is attached to a window device comprising wire winding means for applying tension to the wire,
A movable pulley that abuts against the wire, bends the wire, and can move in a direction substantially perpendicular to the tension;
Urging means for urging the movable pulley from a substantially perpendicular direction with respect to the moving direction of the movable pulley, abutting on a half circumference opposite to the side on which the wire abuts from the center of the movable pulley;
The closed state of the window is displayed using the displacement of the movable pulley.
[0009]
[Means of claim 2]
The remote window closing confirmation device according to claim 1,
The movable pulley is provided with a pointer interlocking with the movement of the movable pulley, and the closed state of the window is displayed by the change of the pointer.
[0010]
[Means of claim 3]
In the remote window closing confirmation apparatus of Claim 1 or Claim 2,
A fixed pulley that restricts the bending range of the wire is provided on both sides or one side of the movable pulley,
A steel ball that contacts the movable pulley is provided at the tip of the urging means.
[0011]
[Means of claim 4]
In the remote window closing confirmation apparatus in any one of Claims 1 thru | or 3,
The wire winding means winds the wire by rotating a manual winding lever, and applies tension to the wire.
[0012]
[Effects of the Invention]
When the wire is wound by the wire winding means, tension is generated in the wire, and a transition force is applied to the window to close the opening. Then, the window changes with respect to the frame, and the window closes the opening of the frame.
When tension is further applied to the wire in a state where the window closes the opening of the frame, this tension is applied to the movable pulley. Since the movable pulley is urged by the urging means from a direction substantially perpendicular to the transition direction, the movable pulley is pushed to the side where the wire abuts. For this reason, when the tension | tensile_strength of the wire given to a movable pulley is weak, the transition of a movable pulley is suppressed.
[0013]
Furthermore, when the tension of the wire increases, the force that the movable pulley tries to change increases, and when the tension of the wire reaches the set value and the movable pulley starts to change, the component force ratio (appendix) transmitted to the urging means is added. The biasing force by the biasing means / the shifting force of the movable pulley) increases, and the contact position of the biasing means that contacts the movable pulley is shifted by a slight increase in tension, and the movable pulley makes a full stroke. From this change of the movable pulley, the operator of the wire winding means can know whether or not the tension required for closing the window is generated in the wire. That is, it can be confirmed from the transition of the movable pulley that the window is closed.
[0014]
【The invention's effect】
As shown by the above action, the operator of the wire winding means can confirm that the window is closed from the transition of the movable pulley. For this reason, depending on the operator, it is possible to eliminate the problem of misunderstanding that the window is open but closed.
[0015]
In addition, the movable pulley is disposed in contact with the wire and bent so that the space for installing the movable pulley is small. On the other hand, the urging means urges the movable pulley from a direction substantially perpendicular to the moving direction of the movable pulley. That is, since the urging means is arranged along the direction in which the wire extends, the arrangement space of the urging means can be small. Thus, since the installation space for the movable pulley and the arrangement space for the urging means are both small, the remote window closing confirmation device can be miniaturized.
In addition, since the remote window closing confirmation device can be reduced in size, it can be housed in the box of the wire winding means.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described based on examples and modifications.
[Configuration of Example]
1 to 3 show an embodiment, FIG. 1 is a schematic perspective view showing an internal structure of a remote window closing confirmation device, FIG. 2 is an operation explanatory diagram of the remote window closing confirmation device, and FIG. 3 is an outline of the window device. FIG.
[0017]
The window device 1 is shown in FIG. 3, and is roughly divided into a frame 2 attached to a building, a window 3 for opening and closing an opening in the frame 2, and a pressing means for biasing the window 3 in the opening direction. 4. A wire 5 for pulling the window 3 in the closing direction and a wire winding means 6 for winding the wire 5.
Further, the wire winding means 6 of the window device 1 is assembled with a remote window closing confirmation device 7 for displaying to the operator whether or not the window 3 has been securely closed when winding the wire 5. .
[0018]
The frame 2 is a rectangular frame fixed to the opening of the building, and includes an opening 2a inside. A sealing material (not shown) is attached around the opening 2a so as to prevent a gap between the opening 2a and the window frame 3a from being generated when a window frame 3a described later is pressed. Is provided.
[0019]
The window 3 is supported so as to be able to turn and change with respect to the frame 2 (in this embodiment, the lower side of the frame 2), and opens and closes the opening 2 a by turning and changing. It consists of a window frame 3a that can be in close contact with 2a via packing, and a window glass 3b that is airtightly mounted in the window frame 3a.
[0020]
The pressing means 4 is an elastic body having one end fixed to the side of the frame body 2 and the other end fixed to the window frame 3a, and the window frame 3a is framed by the action of a compression coil spring or compressed gas disposed inside. It is energized in the direction away from 2. The action of the pressing means 4 is to push the window frame 3a away from the frame body 2 to open the window 3 when the tension of the wire 5 is released.
[0021]
The wire 5 is a thin metal rope having one end fixed to the frame 2 or the like and the other end capable of being wound around the wire winding means 6, and this wire 5 is provided at the rotating end of the window frame 3a. The wire 5 is passed through the window frame pulley 5a so that the tension of the wire 5 acts on the window 3 via the window frame pulley 5a. In addition, in FIG. 3, the guide pulley 5b attached other than the window frame pulley 5a is for smoothly changing the direction of the wire 5 extending in the linear direction.
[0022]
As described above, the window frame 3 a is provided so that the tension of the wire 5 acts via the window frame pulley 5 a, so that the wire winding means 6 winds the wire 5 and applies tension to the wire 5. When this occurs, the window frame 3a of the window 3 is pulled toward the frame body 2 by the applied tension, and the window 3 is pivoted and moved to close the opening 2a.
[0023]
The wire winding means 6 operates a winding pulley (not shown) in which the other end of the wire 5 is fixed, a one-way clutch (not shown) that rotates the winding pulley in only one direction, and the winding pulley. And a release button 6b for releasing rotation of the take-up pulley in the other direction in the one-way clutch, and is housed in a handle box 6c assembled to a building wall or the like. ing.
[0024]
The remote window closing confirmation device 7 is arranged in the middle of the wire 5 in the handle box 6c of the wire winding means 6, and the handle box 6c is used for visually recognizing the pointer 8 arranged inside. A display window 9 is provided.
The remote window closing confirmation device 7 is assembled to the support frame 10 and is composed of a movable pulley 11, two fixed pulleys 12, an urging means 13, and a pointer 8, which are shown in FIGS. I will explain.
[0025]
The movable pulley 11 is in contact with the wire 5 and receives tension from the wire 5, and bends the wire 5 in a range of several degrees to several tens of degrees. The support shaft 11a of the movable pulley 11 is in the tension direction of the wire 5 ( In this embodiment, it is supported by a slot (not shown) extending in the vertical direction (horizontal direction in this embodiment) with respect to the vertical direction. As a result, the movable pulley 11 is provided so as to be movable in the horizontal direction.
[0026]
The two fixed pulleys 12 are arranged on both the upper and lower sides of the movable pulley 11 and the support shaft 11 a is fixed to the support frame 10, and regulates the bending range of the wire 5 by the movable pulley 11.
[0027]
The biasing means 13 of the present embodiment abuts on the half circumference side opposite to the side on which the wire 5 abuts from the center of the movable pulley 11, and is substantially in the vertical direction (vertical direction) with respect to the displacement direction (horizontal direction) of the movable pulley 11. Therefore, the movable pulley 11 is urged. That is, an urging force F2 that resists the shifting force F1 of the movable pulley 11 from the vertical direction is generated.
[0028]
The urging means 13 of this embodiment adjusts the urging force of one compression coil spring 13a extending in the vertical direction, a steel ball 13b that is urged by the compression coil spring 13a and abuts against the movable pulley 11, and the compression coil spring 13a. And an adjusting screw 13c. The adjusting screw 13c allows the movable pulley 11 to be fully increased with a slight increase in tension when the tension of the wire 5 reaches a predetermined tension (a tension generated when the window 3 is securely closed, for example, 20 to 40 kg). The urging force F2 is adjusted so as to make a stroke.
The biasing means 13 also serves as a return spring that pushes back the movable pulley 11 when the window 3 is opened, that is, when the tension of the wire 5 is released. A rotating body such as a roller may be used instead of the steel ball 13b.
[0029]
The pointer 8 is supported on the outside of the support frame 10 so as to be capable of rotating and changing, and is also rotated and moved in conjunction with the change of the support shaft 11a of the movable pulley 11. The change of the pointer 8 is transferred to the handle box 6c. It is displayed in the provided display window 9.
In addition, the rotating end of the pointer 8 is provided with display means for distinguishing and displaying the open state and the closed state of the window 3 (for example, red and green color coding). In FIG. When the movable pulley 11 is in the position of the two-dot chain line, the closed state (for example, red) is displayed from the display window 9. ing.
[0030]
[Operation of Example]
Next, the operation of the above embodiment will be described.
When opening the window 3, the tension applied to the wire 5 is released by operating the release button 6 b of the wire winding means 6, and the pressing means 4 pushes the window frame 3 a away from the frame body 2. Then, the window frame 3a is pivoted in the opening direction, and the window 3 is opened.
[0031]
When the window 3 is closed, the wire 5 is wound around the winding pulley by rotating the winding lever 6 a of the wire winding means 6, and tension is generated in the wire 5. When tension is generated in the wire 5, the wire 5 pulls the window frame 3 a of the window 3 toward the frame body 2 against the urging force of the pressing means 4. As a result, the window 3 is pivoted in the closing direction, and the opening 2a in the frame 2 is closed.
[0032]
When each window 3 is closed, each window 3 is pressed against the packing of the frame body 2 and cannot turn and change, and the tension applied to the wire 5 increases rapidly. As the tension of the wire 5 increases, the displacement force F1 applied to the movable pulley 11 increases. Since the movable pulley 11 is pushed back by the urging means 13, the movable pulley 11 does not change when the tension is smaller than a predetermined value. That is, the open state (for example, green) remains displayed by the pointer 8 on the display window 9 of the handle box 6c.
[0033]
When the take-up lever 6a is further rotated, the tension of the wire 5 increases and the transition force F1 of the movable pulley 11 increases. When the tension of the wire 5 reaches the set load, the movable pulley 11 starts to change. When the tension of the wire 5 is further increased, it can be moved with a slight increase in tension by increasing the component force ratio F2 / F1 of the axial load (biasing force F2) transmitted to the compression coil spring 13a via the steel ball 13b. The position of the steel ball 13b in contact with the pulley 11 is shifted, and the movable pulley 11 makes a full stroke. Due to the full stroke of the movable pulley 11, the pointer 8 is rotated, and the closed state (for example, red) is displayed by the pointer 8 on the display window 9 of the handle box 6c. As a result, the operator can confirm that each window 3 has been securely closed, and finishes the turning operation of the winding lever 6a.
[0034]
[Effects of Examples]
As shown in the above operation, the remote window closing confirmation device 7 according to the present embodiment allows the operator operating the winding lever 6a of the wire winding means 6 to close the window 3 when the window 3 is closed. It can be confirmed from the display of the pointer 8 that the window 3 is securely closed. For this reason, depending on the operator, there is no problem of misunderstanding that the window 3 is open but closed, and it is possible to prevent damage from wind and rain entering the building.
[0035]
In addition, since the movable pulley 11 is disposed by contacting the wire 5 and bending the wire 5, the space for installing the movable pulley 11 can be small. On the other hand, since the urging means 13 is arranged along the direction in which the wire 5 extends, the arrangement space of the urging means 5 can be small.
Thus, since the installation space of the movable pulley 11 and the arrangement space of the urging means 13 are both small, the remote window closing confirmation device 7 can be miniaturized and stored in the handle box 6c of the wire winding means 6. Can do.
In addition, workability improves because the remote window closing confirmation device 7 can be stored in the handle box 6c.
[0036]
[Modification]
In the above embodiment, an example in which one urging means 13 is provided as an example of the urging means 13 that abuts the movable pulley 11 on the side opposite to the wire 5 is shown, but as shown in FIGS. Two urging means 13 may be provided.
In the above embodiment, the compression coil spring 13a is used as an example of the biasing means 13 that applies the biasing force to the movable pulley 11. However, the torsion spring 13d shown in FIG. Other means such as rubber may be used. In FIG. 6, a roller 13e is used instead of the steel ball 13b.
[0037]
In the above embodiment, an example in which the movement of the pointer 8 linked to the movable pulley 11 is displayed to the user is shown. However, a part of the movable pulley 11 (for example, the movable pulley 11 and the support shaft 11a) is shown to the user. You may provide so that it may display.
In the above embodiment, the remote window closing confirmation device 7 is provided integrally with the wire winding means 6. However, the remote window closing confirmation device 7 may be provided separately from the wire winding means 6.
