Detachable sliding door automatic switchgear

(Technology field)

The present invention relates to a removable sliding door automatic opening and closing device, and more particularly, to be detachably installed on an existing sliding door, which can be opened and closed automatically according to an operating time schedule input to a timer switch. It relates to a sliding door automatic opening and closing device.

(Prior art)

Ventilation and temperature control of indoor air by opening and closing windows and living room doors to keep the room comfortable are common in everyday life.

In summer, the temperature is hot enough to reach 25 degrees or more at night, but the temperature is low enough to feel cool at late night or dawn, and the fall season is cool enough at night. When the temperature is too cold, it is often a sharp crossover. In general, when the temperature is high, opening a window or living room door, or using a cooling device such as an air conditioner to lower the temperature of the room, when the temperature drops by closing the door or stopping the cooling mechanism, to cope with the temperature change.

Opening and closing doors is not uncomfortable during daytime activities, but getting up and closing the door during bedtime is quite inconvenient and annoying.

For example, if the temperature at night is hot and the temperature at dawn is typical of chilly early autumn, you might wake up at night when you sleep by closing the window against the dawn at bedtime. Bedtime is often left open. However, in the early hours of deep sleep, people often get sick by not having to close their windows and go to bed to catch a cold.

In a typical tropical night of midsummer, when it is hot overnight and the temperature drops slightly at dawn, sleeping on air conditioners until dawn is not only economically expensive because it is exposed to the cold air of the air conditioners for a long time, but also increases the power consumption. However, just keeping the windows open without using the air conditioner will not cool the hot summer temperatures. Therefore, the air conditioner may be adjusted to stop the air conditioner at dawn when the temperature decreases relatively, and the windows may be closed and going to bed to improve the efficiency of the air conditioner. Once you're done, keep your windows open for a good night's sleep. However, getting up at bedtime and opening a window is a bother.

If the windows are closed and going to bed to increase the effectiveness of the air conditioner during the hot summer, when the air conditioner is continuously operating and going to bed, it is necessary to open the windows and ventilate occasionally to keep the room comfortable and prevent the cooling bottle. have. However, it is not only annoying to forget to get up and close the windows from time to time while sleeping, but it is easy to forget and pass.

Therefore, if there is a device that does not need to open and close the door by hand by automatically opening and closing windows and the like according to the scheduled operating time schedule, it will help to sleep well and stay healthy in the summer night.

It is an object of the present invention to operate the air conditioner in the summer season or during the season when the day is a bad season, a sliding door that is widely used as a window or a living room door automatically opens or closes according to the time schedule that is reserved in advance. It is a sliding door automatic opening and closing device that can maintain a proper temperature and allow ventilation, and provides a removable sliding door automatic opening and closing device that can be easily installed and detached from an existing door.

An object of the present invention described above, the drive drum by blocking the transmission of the rotational force of the motor to the drive drum when the torque load of the reversible motor, the drive drum rotated by the motor, and the drive drum or more than the firing value is applied to the drive drum A drum drive device including a safety device that swings against the axis of rotation of the motor, between the drive drum and a rope hanger member independently spaced from the drum drive device, and the drive drum when the drive drum rotates. And a timer switch for inputting an operation schedule of the drum drive device and a band-shaped drive rope rotated between the rope hanger members, and the drum drive device on one side of the sliding door with a sliding door interposed therebetween. And secure the rope hanger member next to the other side of the sliding door. In the state in which the drive rope is rotatably stretched between the drive drum and the rope hanger member, the drive rope is fixed to the door frame of the sliding door to be opened and closed, thereby being detachably installed to the sliding door. Characterized in that, by a removable sliding door automatic opening and closing device.

The safety device of the drum drive device includes a compression plate and the driving drum which are fixed to the rotary shaft to be integrally rotated with the rotary shaft of the reversible motor, and are in contact with the flange surface of the driving drum inserted into the rotary shaft of the motor. A crimping spring for crimping and contacting the flange surface with the crimping plate, wherein the driving drum is rotated by the rotational force of the motor by frictional contact with the crimping plate by the crimping spring, and presses the pressing force of the crimping spring. When a torque load greater than a predetermined value acts on the drive drum, the flange face of the drive drum and the press plate slide, so that the drive drum swings about the axis of rotation of the motor.

Hereinafter, with reference to the accompanying drawings, a removable sliding door automatic opening and closing device according to the present invention will be described in detail. The following specific examples merely illustrate the invention and do not limit the scope of the invention.

1 is a cross-sectional view showing a removable sliding door automatic opening and closing device according to the present invention, Figure 2 is a cross-sectional view of the drum drive device, Figure 3 is a perspective view showing an example of a safety device. As shown, the removable sliding door of the present invention The automatic opening and closing device 1 is basically configured to include a drum drive device 3, a drive rope 5, a rope hook member 7, and a timer switch 9.

The drum drive device 3 has a structure in which the reversible motor 11, the drive drum 15 inserted into the rotary shaft 13 of the reversible motor 11, and the safety device 17 are provided in the casing 19. The drum drive device 3 is a device that provides power to open and close the sea sliding door by rotating the drive drum 15 by rotating the drive drum 15 by the reversible motor 11.

The reversible motor 11 is a forward and reverse rotatable motor capable of selectively rotating the drive drum 15 clockwise or counterclockwise. The reversible motor 11 to be used is not particularly limited, but the use of a small reversible deceleration motor with a slow rotational speed can open and close the sliding door slowly and quietly and can manufacture the sliding door automatic switching device compactly at low weight. It is preferable at the point. In Fig. 1, reference numeral 12 denotes a selector switch for selecting the rotational direction of the reversible motor 11, and this selector switch 12 may be provided in the timer switch 9 without being installed in the motor 11.

The drive drum 15 which walks and rotates the drive rope 5 is inserted in the rotating shaft 13 of the said reversible motor 11. The drive drum 15 is not fixed on the rotary shaft 13 of the motor 11 to be directly rotated by the motor 11, but is indirectly rotated through a safety device 17 which will be described in detail later. That is, the drive drum 15 is inserted so that the drive drum 15 can be idle about the rotation shaft 13 without being tightly fixed to the rotation shaft 13 of the motor 11. To this end, the shaft insertion hole of the driving drum 15 is formed slightly larger than the rotation shaft 13 of the motor 11. As a result, the rotating shaft 13 of the motor has a function of supporting the driving drum 15 to be held in place in the casing 19 while providing rotational force indirectly to the driving drum 15. The drive drum 15 is preferably formed to be concave toward the center portion thereof in order to prevent the drive rope 5 rotating therefrom from slipping toward the flanges 27 and 27 'of the drum 15.

The transmission of power (rotational force) between the rotary shaft 13 of the motor 11 and the drive drum 15 is via a safety device 17. The safety device 17 prevents the rotational force of the motor 11 from being transmitted to the driving drum 15 when a torque load of a predetermined value or more is applied to the driving drum 15 from the driving rope 5 to prevent the rotation shaft 13 of the motor. ) Is a device that prevents an excessive load from being applied to the motor by allowing the motor to swing against the drive drum 15.

The rotation speed of the motor 11 and the operation of the timer switch 9 are precise and the time input to the timer switch 9 is accurate, so that the motor stops at the moment when the sliding door is fully opened or closed, and the door frame of the sliding door Under the premise that obstacles exist on the rails or that the sliding door cannot be opened or closed only by the power of the motor due to moisture or the like, the driving drum 15 directly rotates from the rotary shaft 13 of the motor without a separate safety device. It may be configured to receive and rotate. However, in reality, it is not certain that such a situation as described above will not occur, and when there is no safety device, the motor will continue to operate in a state where the door can no longer be moved, so that the sea motor is overloaded and the device of the present invention. Can not be completely ruled out or the sliding door is deviated from the rail.

Therefore, in the sliding door opening and closing device according to the present invention, even after the sliding door is completely opened or closed, the motor continues to rotate to overload the drum drive device 3, or the sliding door may be opened or closed by the force of the motor 11. The safety device 17 is included in the drum drive device 3 in case no situation occurs.

As the safety device 17 used in the present invention, when the torque load of the drive rope 5 acting on the drive drum 15 is greater than or equal to a predetermined value, the rotational force of the motor 11 is transmitted to the drive drum 15. If the rotational shaft 13 of the motor has a function of turning against the driving drum 15 by blocking it is not particularly limited.

1 to 3 show an example in which the pressing plate 21 and the pressing spring 23 are used as the safety device 17. Since the drive drum 15 is installed in an inclined manner with respect to the rotating shaft 13 of the motor, the driving drum 15 even if the motor 11 is rotated in a state where the pressing plate 21 and the pressing spring 23 are not mounted. ) Does not rotate. The pressing plate 21 is inserted into the rotating shaft 13 so as to be integrally rotated with the rotating shaft 13 of the motor, and fixed to the fixing pin 25, and is in contact with the flange 27 of the driving drum 15. Then, the pressing spring 23 compresses the flange 27 and the pressing plate 21 of the driving drum 15 by elasticity to make friction contact. Thus, the drive drum 15 is not directly rotated by the rotary shaft 13 of the motor, but is directly rotated by the rotary shaft 13 of the motor and flanged of the drive drum 15 by the compression spring 23. It rotates by the frictional contact with the crimping plate 21 pressed against (27). However, when a torque load equal to or greater than the pressing force of the pressing spring 23 acts on the driving drum 15 from the driving rope 5, the flange 27 and the pressing plate 21 slide together, and eventually the motor The rotating shaft 13 of the rotation of the drive drum (15) is turned so that only the motor 11 and the pressing plate 21, the drive drum 15 does not rotate. Therefore, even if a tog load of a predetermined value or more exceeding the pressing force of the crimping spring 23 acts on the drive drum, there is no fear that the drive device 3 will be overloaded and the device will be damaged.

It is preferable to form the crimping plate 21 and the flange 27 of the driving drum 15 in contact with each other so that the friction coefficient is high so as to be in contact with the widest possible area so as to receive sufficient frictional resistance. The crimp spring 23 prevents the crimp plate 21 and the flange 27 of the drive drum 15 from slipping against each other and the excessive load applied to the drive drum 15 when the sliding door is normally opened and closed. When the torque load is applied to the drive drum 15, the pressing plate 21 and the flange 27 are pushed to each other to press the flange 27 of the pressing plate 21 and the driving drum 15 inwardly. It has elasticity as much as it can.

FIG. 3 shows an example of a pressing spring 23 composed of two members in which a plurality of claws 31 are formed in a semicircular elastic band steel 29. As shown in FIG. The pressing spring 23 is installed by contacting the flange 27 of the driving drum 15 with the pressing plate 21 and then pressing these two members from above or below or from side to side. In the pressing plate 21, by forming the jaw 33 at the circumferential end of the surface not in contact with the flange 27 of the drive drum 15, the claw 31 of the pressing spring 23 is caught, It is desirable for the compression spring not to be easily released.

1 to 3, an example in which the pressing plate 21 is fixed to the end of the rotation shaft 13 of the motor and the driving drum 15 is positioned between the pressing plate 21 and the motor 11 is illustrated. The plate 21 is fixed to the rotary shaft 13 close to the motor 11 so that the pressing plate 21 is positioned between the motor 11 and the driving drum 15, and the two pressing plates are driven by the driving drum ( It is also possible to arrange the two flanges 27 and 27 'of the driving drum and the respective pressing plates by two sets of compression springs by arranging them on both flanges 27 and 27' of 15).

The drive rope 5 hangs on the drive drum 15 of the drive device 3. As shown in FIG. 1, the drive rope 5 is formed in one band shape as a whole, and is wound around the drive drum 15 through a rope guide hole 37 formed in the casing 19 after the drum drive device. It is outward from (3). When the driving drum 15 is rotated while the driving rope 5 is tightly hung on the driving drum 15, the driving rope 5 is as if the belt and the sense of the belt transmission are rotated. In order for the drive rope to be rotated by the rotation of the drive drum 15, a sufficient friction force must be applied between the drive drum 15 and the drive rope 5. For this purpose, the drive rope is driven by the rope hook member 7 in the present invention. (5) is tightened to the drive drum 15. The rope hanger member 7 is independently spaced apart from the driving device 3, and when the sliding door opening and closing device 1 of the present invention is installed on the sliding door, the driving device is fixed with the sliding door 55 interposed therebetween. On the opposite side of the side is fixed to the bottom or wall of the vertical door frame 57 next to the sliding door. In order to make the drive drum 15 and the drive rope 5 contact with a high frictional force, it is preferable that the drive drum is made of a high friction material or the rubber and the wound high friction material are coated on the surface where the drive rope is in contact.

Hereinafter, the driving rope 5 will be described in more detail while explaining a method of installing the removable sliding door automatic opening and closing device according to the present invention to the sliding door and the opening and closing operation of the sliding door.

Removable sliding door automatic opening and closing device 1 according to the present invention, the driving device 3 is fixed to one side of the sliding door 55 with the sliding door 55 in the center and the other side of the sliding door 55. After the rope hanger member 7 is fixed, the drive rope 5 is rotatably stretched between the drive drum 15 and the rope hanger member 7, and then any point of the drive rope 5 is fixed. It is installed on the sliding door 55 in a manner that is fixed to the door frame 63 of the inner sliding door 61 to be opened and closed. When the driving drum 15 rotates while the apparatus is installed in the sliding door 55, the driving rope 5 is connected between the driving drum 15 and the rope hanger member 7 in accordance with the rotation direction of the motor 11. At the clockwise or counterclockwise rotation, the inner sliding door 61, which is restrained at one point of the driving rope 5, moves to the left or right to be opened and closed.

The drum drive device 3 may be fixedly attached to the bottom of the vertical door frame 57 of the sliding door 55 or to the wall next to the sliding door, and as shown in FIG. Since the installation rope 6 connected to the casing 19 is hooked to a door frame 57 or a ring or nail attached to the wall, the installation rope 6 can be installed in the sliding door 55.

When using the installation rope (6), one end is fixedly connected to the casing (19) of the drive device (3), and the other end is attached to the hook (39) by the hook attached to the bottom of the vertical door frame (57) or the wall ( 65) or to nail (see Figure 6). At this time, as the hook 39, the hook as shown in Figure 1, the hook having a spool (spoo1; 41) which can wind the installation rope 6 and the guide slit 43 is inserted into the guide rope 6 is guided By using 39, it is preferable to adjust the length of the installation rope 6 according to the size of the sliding door 55 so that the length between the hook 39 and the rope hanger member 7 can be established.

When the drum drive device 3 is fixedly attached to the door frame 57 of the sliding door 55 or the wall next to the sliding door, the casing 19 is directly attached to the door frame or the like, or a fixture is formed in the casing 19. And by attaching a bracket to the door frame or wall can be fixed by inserting the fastener to this bracket.

The rope hanger member 7 is fixed to the bottom of the vertical door frame 57 'next to the sliding door on the opposite side to which the drive device 3 is fixed or to a nail or a ring 65' attached to the wall (see Fig. 6). ). As mentioned above, in order for the drive rope 5 to be rotated by the rotation of the drive drum 15, the drive rope 5 must be tightened between the drive drum 15 and the rope hanger 7. . In order to smoothly rotate the drive rope 5 and to maintain the tension of the drive rope, as shown in FIG. 1, the pulley 8 on which the drive rope 5 is caught and the pulley 8 are rotated. A pulley support 10 that possibly supports, a hook 16 that can be hooked to a ring or nail attached to a door frame or wall, and a spring that elastically connects the hook 16 to the pulley support 10 ( It is preferable to use the rope hanger member 7 made of 14). The spring 14 is for providing a cushioning force to the drive rope 5

One point of one of the two lines of driving ropes 5 passing between the drum drive device 3 and the rope hanger member 7 is approximately the center of the door frame 63 of the inner sliding door 61 which is opened and closed. Is going to In order to easily fix the drive rope 5 to the door frame 63 of the inner sliding door 61, a ring 67 is attached to the door frame 63, and the door frame 63 is attached to the drive rope 5. It is preferable to connect the hook 20 that can be hooked to the ring (67). In addition, according to the size of the sliding door 55 in which the device 1 is installed, the hook so that the length of the drive rope 5 between the drive device 3 and the rope hanger member 7 can be easily adjusted. As 20, similar to the hook 39 of the installation rope 6, the guide slit 24 into which the spool 22 which can wind the drive rope 5 and the drive rope 5 is fitted is guided. It is preferable to use a hook having a hook.

The wire 45 for supplying power to the reversible motor 11 is provided with a timer switch 9 for inputting an operation schedule of the motor 11. As the timer switch, a timer switch 9 having a simple function as shown in FIG. 1 may be used, and timer switches 9 'and 9' having various functions as shown in FIGS. 4 and 5 may be used. Can also be.

The timer switch 9 shown in Fig. 1 is used to close or open the sliding door only once at the scheduled time. The timer switch 9 of Fig. 1 has an operation start time of supplying current by connecting a contact of a switch after a long time elapsed from tens of minutes to several hours as a general job, and generally opening and closing of a sliding door is completed. It is a timer switch that can input the duration of operation to stop the motor by opening the contact and cutting off the current after a short time of several tens of seconds.

For example, a long time timer 47 for inputting a long time (operation start time), a short time timer 49 for inputting a short time (operation duration), and an on-off switch 51 are provided in one switch box ( 53 may be used. The on-off switch 51 is a main switch that interrupts current to the motor 11. As mentioned above, the timer switch 9 has a reversible motor 11. The selector switch can be installed to select the direction of rotation.

Timer switch 9 shown in Figure 4, according to the sliding door opening and closing operation schedule input by the user, not only opening and closing the sliding door, but also determined after repeating the opening and closing with a certain period It is a switch configured to be able to finally open the sliding door at a time.

For example, as shown in Fig. 4, the opening and closing repetition mode 153 for repeatedly opening and closing the sliding door until the reserved time and the opening mode 155 for opening the door at the reserved time and the door at the reserved time Mode switching switch 151 to select the closing mode 157 to close, and the mode switching switch 151 when all opening and closing operations are completed when the lap repeat mode 153 is selected in the mode switching switch 151. When the open mode 155 or the closed mode 157 is selected in the time setting timer 159 for inputting the time when the opening or closing is started, when the opening and closing repeat mode 153 is selected in the mode switching switch 151 The opening and closing interval setting timer 161 which inputs the time interval between each sliding door opening and closing operation in the case, and when the opening and closing repetition mode 153 is selected in the mode changeover switch 151 until the door is closed again. On closing entering time The setting timer 163, the operation duration setting timer 165 which inputs the operation duration time which the power supply is supplied to the motor 11, and the sliding door opens and closes, and the main ON- which controls an electric current to the motor 11, The timer switch 9 'provided with the off switch 167 in one switch box 169 can be used.

The opening and closing repetition mode 153 is a mode that can be used to periodically open the sliding door to ventilate when the air conditioner is running and going to sleep overnight, and to finally open the door when the air conditioner is stopped. When this mode 153 is selected, power is supplied to the motor 11 periodically (for example, every 1 hour) to open and close the sliding door periodically (for example, once every hour). At this time, the opening and closing period of the door is input by the opening and closing interval setting timer 161, the opening and closing interval setting timer 161 so as to enter the time interval, such as 10 minutes, 30 minutes, 1 hour, 2 hours. Can be configured. For example, when the mode switching switch 151 is selected as the opening and closing repeating mode 153 and an hour is input to the opening and closing interval setting timer 161, power is supplied to the motor 11 every hour to open the door.

Once the power is supplied and operated, the motor 11 should be shut off by stopping the power when the door is fully opened. The time until the motor is stopped, that is, the operation duration time, is the operation duration setting timer described above. Enter (165). The duration of operation is determined by the size and weight of the sliding door, the power and speed of the motor, for example from a few seconds to several tens of seconds.

When the indoor ventilation is made to some extent, the open door needs to be closed again, and the period until the door is opened and closed is input by the closing time setting timer 163. The closing time of the door may be selected in consideration of various factors such as the temperature difference between the indoor and outdoor, the wind speed, and the size of the room. For example, 2 minutes, 5 minutes, or 10 minutes may be input. Therefore, each time the sliding door is opened by the opening and closing repetition mode 153, the open door is closed after the time (2 minutes, 5 minutes, 10 minutes, etc.) input to the closing time setting timer 163.

The motor 11, once operated to close the door, must be stopped at the point when the door is fully closed, and the time until the motor is stopped once, i.e. the duration of operation described above, is operated as in the case of opening the door earlier. By the time input to the duration setting timer 165. The repeated opening / closing action of the door is repeated until the time input to the time setting timer 159 and finally ends with the sliding door open.

The open mode 155 and the close mode 157 are modes used when only a door is to be opened or closed at a scheduled time. When the modes are selected, the open / close interval setting timer 161 and the closing time setting timer ( 163 does not operate, only the operation duration setting timer 165 operates. Therefore, when the open mode 155 or the close mode 157 is selected and the desired time is input to the time setting timer 159, power is supplied to the motor 11 at the input time to open or close the door, and the operation continues. After the time input to the time setting timer 165 has elapsed, the power is cut off and the motor 11 is stopped. When the open mode 155 or the closed mode 157 is selected in the timing switch 9 'of FIG. 4, the function is substantially the same as the timing switch 9 of FIG.

Further, in the above timer switch 9 ', the time interval between each sliding door opening and closing operation, which is applied when the opening / closing repetition mode 153 is selected to the mode changeover switch 151, is closed again after opening the door. The time until it is set in the circuit of the timer switch at a constant value suitable for ventilating the room where the air conditioner is operating will not be a major problem for the apparatus of the present invention to perform its function. Thus, as shown in Fig. 5, the time interval between each sliding door opening and closing operation and the time from opening the door to closing again are fixedly set in the circuit of the timer switch, for example, 1 hour and 1 minute. In this case, the timer switch 9 without using the opening / closing interval setting timer 161 and the closing time setting timer 163 may be used.

The functions of the timing switches 9, 9 ', and 9 described above are merely described as an example, and when a combination of a plurality of timers and switches is appropriately configured for a circuit, various operation time schedules of the apparatus can be set. A timer switch may be provided for input. Since the circuit configuration of the timer switch can be easily performed in the technical field according to a necessary function, the detailed circuit configuration will be omitted.

6 and 7, the process of opening and closing the sliding door by the apparatus of the present invention will be described. First, a process of opening a sliding door using the timer switch of FIG. 1 will be described with reference to FIG. 6.

Removable sliding door automatic opening and closing device (1) according to the present invention, the hook (65) of the installation rope (6) is placed on the sliding door (55) attached to the bottom of the left vertical door frame (57) of the sliding door (65) The hook 16 of the rope hanger member 7 on the hook 65 'attached to the bottom of the right vertical door frame 57' of the sliding door, and then the hook 39 of the mounting rope 6 Or after winding the installation rope and / or the drive rope on the spools 41 and 22 of the hook 20 of the drive rope, the drive rope 5 is tensioned between the drive drum 15 and the rope cutting member 7, Hook 20 of the drive rope 5 is hooked to the ring 67 attached to the door frame 63 of the inner sliding door 61 is installed on the sliding door.

When the device 1 of the present invention is installed in the sliding door 55, the plug 69 of the electric wire 45 is inserted into the outlet 71, and the door 61 is connected to the long time timer 47 of the timer switch 9. The time to open the door (operation start time of the device) and set the operation duration time of the motor 11 to the short-time timer 49. The operation duration of the motor 11 is appropriately selected in consideration of the size of the sliding door 55, the rotational speed of the motor 11, and the like. The on-off switch 51 is turned on after setting the rotation direction of the motor 11 with the selector switch 12 so that the reversible motor 11 of the present apparatus rotates toward the opening door.

In this way, when the main unit 1 is installed and sleeps while the inner sliding door 61 is closed, power is supplied to the motor at a reserved time, and the driving rope 5 rotates while the driving drum is dilute, thereby driving. The inner sliding door 61 restrained by the rope 5 is opened. If the motor 11 is operating even when the door is open, or if there is an obstacle in the rail of the horizontal door frame 59 and the door cannot move, and a torque load of a predetermined value or more is applied to the drive drum 15, the drive is performed. Even if the drum 15 slides with respect to the press plate 21 and the motor 11 rotates, the drive drum 15 will not rotate, and therefore, damage or detachment of the device will not occur. The motor 11 stops when the operation duration input to the short time timer 49 elapses. Closing the sliding door can be operated in the same manner as opening the sliding door except setting the rotation direction of the reversible motor 11 in reverse.
