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 or closing windows or living room doors in order to keep the room in a comfortable state are common tasks in daily 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 a living room door, or using a cooling mechanism such as an air conditioner to lower the temperature of the room, and when the temperature drops, 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 can be quite inconvenient and frustrating. 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 go to bed without closing the window and have 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, it is inconvenient to get up at bedtime and open the window.

If the windows are closed and going to bed to improve the efficiency of the air conditioner in the hot summer, when the air conditioner needs to be operated continuously while 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, occasionally getting up and closing a window open and close during bedtime is not only annoying, 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 maintain a good night's sleep and health while operating the air conditioner.

It is an object of the present invention to automatically open or close a sliding door, which is widely used as a window or a living room door, in the hot summer season when the air conditioner is operating or during the bedtime of a busy day, by automatically opening or closing a room temperature. Sliding door automatic opening and closing device that can maintain and ventilate properly, to provide a removable sliding door automatic opening and closing device that can be easily installed and detached to the existing door.

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 perspective view showing an example of a removable sliding door automatic opening and closing device according to the present invention. As shown, the removable sliding door automatic opening and closing device 1 basically consists of a configuration including a rope towing device 3, a rope 5, and a rope towing device operation timer switch 7.

The rope traction device 3 provides power to open and close the sliding door, so that the reversible drive motor 9, the drive pulley 11, and the pair of driven pulleys 13, 13 ′ are for example one side. It has a structure provided in the box-shaped casing 17 which opened the surface. Optionally, pressure rollers 15 and 15 'for pressing the rope 5 towards the pair of driven pulleys may be provided adjacent to each driven pulley 13 and 13'.

The drive motor 9 is a reversible motor capable of selectively rotating the drive pulley 11 in a clockwise or counterclockwise direction, and the shaft hole of the drive pulley 11 is directly or decelerating in the rotary shaft 10 of the motor. It is inserted through the heat so that the drive pulley 11 can be rotated according to the rotation direction of the motor 9. The reversible motor 9 to be used is not particularly limited, but the use of a small reversible deceleration motor with a low rotational speed allows the door to be opened and closed slowly and silently, and the sliding door automatic switchgear can be manufactured compactly at low weight. It is preferable at the point. In Fig. 1, reference numeral 19 denotes a selection switch for selecting the rotational direction of the drive motor 9, and the selection switch 19 may be provided in the timer switch 7 without being installed in the motor 9.

The driving pulley 11 is a pulley that pulls the rope 5 contacted with the power of the motor 9 to the left and right according to the rotational direction of the motor 9, as shown in FIG. 2, as shown in FIG. 2. U- or V-shaped concave grooves 21 are formed on the surface to be in contact with each other, and are provided with gears 23, for example, provided on the shaft 10 of the motor 9 by means of fixing bolts 25. The concave groove 21 has a large frictional force between the driving pulley and the rope by increasing the area where the driving pulley 11 and the rope 5 contact each other, so that when the driving pulley 11 rotates, the rope 5 Is to be towed left and right without slipping.

The driven pulleys 13 and 13 ′ provided on the left and right sides of the drive pulley 11 are pulleys that pull the rope 5 to the left and right in cooperation with the drive pulley 11. Similarly to 11), U- or V-shaped concave grooves are formed on the surface where the rope 5 abuts, and gears 27 and 27 'are provided (see Fig. 2). The gears 27, 27 ′ of the driven pulleys 13, 13 ′ are engaged with the gear 23 of the drive pulley 11, so that when the drive pulley 11 is rotated by the motor 9, the The driven pulleys 13 and 13 'are rotated in the direction opposite to the rotation direction of the drive pulley 11.

The arrangement position of the two driven pulleys 13, 13 'is not particularly limited as long as it is an arrangement that can apply sufficient pulling force to the rope 5 to pull the rope 5 to the left and right, but as shown in FIG. Arranging the driven pulleys 13 and 13 'in the shape of a triangle on the left and right of the driving pulley 11 is preferable in that the size of the rope traction device can be downsized and sufficient traction can be applied to the rope 5.

The frictional force between the rope 3 and the pulleys 11, 13, 13 ′ is such that when the rope towing device 3 is operated to tow the rope 5, a force sufficient to open the sliding door can be obtained. The rope 5 does not slip on the pulleys when acting on 5), but when the resistance exceeding much is applied to the rope 5, it is a frictional force that the rope 5 can slide on the pulleys. In order to increase the friction between the driving pulley 11 and the driven pulleys 13 and 13 'and the rope 5, a rubber of high friction coefficient may be exposed on the surface of each pulley in which the rope 5 is in contact.

Each of the driven pulleys 13 and 13 'is preferably provided with pressure rollers 15 and 15' which allow the rope 5 to be more in close contact with the driven pulley to receive a sufficient frictional force. As the pressure rollers 15 and 15 ', as shown in FIG. 1, a rod 29 hinged to the casing 17 of the rope traction device 3 and rotatably installed at the end of the rod 29 are provided. A roller 31, a spring 33 for pressing the roller 31 toward the driven pulleys 13 and 13 ', and an adjusting screw 35 for adjusting the elasticity of the spring 33 may be used. .

In the rope traction apparatus 3 described above, the components of the casing 17, the pulleys 11, 13, 13 ′, and the pressure roller 15 may be made of light metal or plastic if possible. It is preferable at the point which can reduce the weight of a removable sliding door automatic switching device.

The rope traction device 3 is provided with a bracket 39 as shown in FIG. 1 on the horizontal or vertical door frame 73, 77 by a screw 37 or the like so that it can be easily installed and removed from the door frame of the sliding door. It is preferable to fix the assembly and to assemble the casing (17) of the rope traction device (3) to the bracket (39).

When using the bracket 39 of FIG. 1 to fix the device 1 of the present invention to the door frame of the sliding door, the bracket 39 is attached to the horizontal door frame 73 by a screw 37 or the like. Therefore, the installation and separation is not easy, and after removal, nail marks remain on the door frame 73, which damages the sliding door and damages the aesthetics. Therefore, in the present invention, when the rope traction device 1 is installed on the sliding door, it is more preferable to use the assembled bracket 101 which does not leave nail marks as the bracket to be attached to the sliding door.

3 is a perspective view of the prefabricated bracket 101, and FIG. 4 is a front view of the prefabricated bracket 101 of FIG. 3 installed on the vertical door frame of the sliding door. As shown, the prefabricated bracket 101 is mounted on one side 105 of the U-shaped assembly table 103 having a width slightly wider than that of the vertical door frame 77 of the sliding door made of wood or aluminum. An assembling table fixing screw 107 for fixing 103 to the vertical door frame 77 is provided, and the other side 109 is slit 113 so as to be fixed by positioning in the thickness direction of the vertical door frame 77. ) -Shaped cross-shaped support 111 is fastened by the support fixing screw 115. A bracket 119 is attached to the center side 117 of the assembly table 103 so that the casing 17 of the apparatus of the present invention can be fitted and fixed.

The assembled bracket 101 of this structure loosens the fixing screw 107 of the one side side 105 of the assembly table 103 as much as possible, and loosens the fixing screw 115 of the support table 111 to assemble the support table 111. Sliding to the position as far as possible from the center side 117 of the base 103, and inserted into the vertical door frame 77 of the sliding door, and then tighten the assembly table fixing screw 107 to tighten the assembly table 103 After fixing to the door frame 77, the support 111 is as close as possible toward the center side 117 and tighten the support fixing screw 115, it is firmly fixed to the vertical door frame 77. Using the prefabricated bracket 101 described above, it is possible to install and remove the bracket as needed without damaging the door frame of the sliding door.

A rope 5 is installed on the pulleys 11, 13, 13 ′ of the rope traction device 3. That is, as shown in FIG. 1, the rope 5 is inserted into the rope guide hole 41 formed on both sides of the casing of the rope traction device 3, and in turn, the driven pulley 13, the driving pulley 11, and The rope pull device 3 is installed in such a manner as to fit into the recessed grooves 21 of the respective pulleys in the order of the other driven pulleys 13 '. Both ends of the rope 5 are fixed by hooks or nails attached to door frames or walls on both sides of the sliding door, and connect hooks 43 and 43 'at both ends of the rope 5 so that the rope can be easily hooked. It is preferable. At least one of the two hooks 43 and 43 'has a spool 45 to which the rope 5 can be wound using a hook having a guide slit 47 through which the rope is fitted, thereby sliding the length of the rope. It is desirable to be able to adjust the size of the door.

The length of the rope 5 is about the length corresponding to the maximum horizontal length of a sliding door that is normally used in the state installed in the rope traction device 3, in use, depending on the size of the door to which the device is attached, It is wound around the spool 45 of the hook 43 to adjust its length.

According to the structure of the rope traction device 3 and the rope 5 as described above, when the motor 9 is rotated, the driving pulley 11 and the two driven pulleys 13, 13 'are rotated, and eventually The rope constrained to the pulleys by the high friction force and the pressing force of the pressure rollers 15 and 15 'receives a force to be pulled left or right according to the rotational direction of the motor. At this time, if the hooks 43 and 43 'of the rope 5 are not caught by any fixed object, the rope 5 will move to the left or right with respect to the rope towing device 3, but the hooks at both ends of the rope 5 ( If the 43, 43 'is prevented from being moved by a hook or the like, the rope traction device 3 moves left and right along the rope 5 according to the rotational direction of the drive motor 9.

Therefore, the hook motor 43, 43 'is fixed to the door frame or the hook or nail attached to the wall, and the drive motor 9 in the state in which the rope traction device 3 is fixed to the door frame by the brackets 39, 101. Rotating), the sliding door is moved to the left and right together with the rope traction device (3) to move left and right along the rope (5), it is possible to open and close the sliding door by this principle. For example, as shown by the arrow in FIG. 1, when the drive pulley 11 rotates counterclockwise by the motor 9, the left and right driven pulleys 13 and 13 ′ are clockwise due to gear engagement. Is rotated, and the rope traction device 3 is moved to the left along the rope while the left and right hooks 43 and 43 'of the rope 5 are fixed.

The electric wire 49 for supplying electric power to the rope traction device 3 is attached with a timer switch 7 for inputting an operation schedule of the motor 9. As the timer switch 7, a timer switch having a simple function as shown in FIG. 1 may be used, and a timer switch having various functions as shown in FIG. 5 may be used.

The timer switch 7 shown in Fig. 1 is used to close or open the sliding door only once at the scheduled time. The timer switch 7 of FIG. 1 has an operation starting time for supplying current by connecting a contact of a switch after a long time elapsed, which generally ranges from several tens of minutes to several hours, and generally opens and closes a sliding door. 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 51 for inputting a long time (operation start time), a short time timer 53 for inputting a short time (operation duration), and an on-off switch 55 are provided in one switch box ( 57) can be used. The on-off switch 55 is a main switch for regulating the current in the rope traction device 3. As mentioned above, the timer switch 7 may be provided with a selection switch for selecting the rotation direction of the drive motor 9.

The timer switch 7 ′ shown in FIG. 5 not only opens and closes the sliding door according to the sliding door opening / closing operation schedule input by the user, but also repeats opening and closing with a certain period. It is a switch configured to be able to finally open the sliding door at a predetermined time.

For example, as shown in FIG. 5, the door is opened and closed at a scheduled time, and 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. Mode switching switch 151 to select the closing mode 157 to close, the mode switching switch 151 when the opening and closing repeat mode 153 is selected in the mode switching switch 151 and 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. Shutdown time to input time The setting timer 163, the operation duration setting timer 165 which inputs the operation duration which power is supplied to the motor 9 of the rope traction apparatus 3, and a sliding door opens and closes, and a current to a rope traction apparatus The timer switch 7 'provided with one switch box 169 can be used as the main on-off switch 167 which controls the control.

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 9 of the rope traction device 3 periodically (for example, every hour), so that opening and closing of the sliding door is performed periodically (for example, once every hour). Is done. 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, for example, to input a time interval, such as 10 minutes, 30 minutes, 1 hour, 2 hours, etc. Can be configured. For example, if the mode selector switch 151 is selected as the open / close repeat mode 153 and an hour is input to the open / close interval setting timer 161, power is supplied to the rope traction device 3 every hour to open the door. do.

The rope tow device 3 once powered and operated should be shut off by stopping the power supply when the door is fully opened. The time until the operated rope tow device is stopped, that is, the operation duration is Input to the duration setting timer (165). The duration of operation is determined by the size, weight of the sliding door, the power and speed of the motor, etc., for example from several seconds to several tens of seconds.

When the indoor ventilation is made to some extent, the open door must be closed again, and the period of time 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 according to the user's taste 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 rope towing device 3 actuated to close the door must be stopped when the door is fully closed, and the time until the operated rope towing device stops, i.e. the duration of operation described above, Similarly, it depends on the time input to the operation 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 the 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 closed mode 157 is selected and the desired time is input to the time setting timer 159, power is supplied to the rope traction device 3 at the input time to open or close the door, After the time input to the operation duration setting timer 165 has elapsed, the power is cut off and the apparatus 3 is stopped. When the open mode 155 or the closed mode 157 is selected in the timing switch 7 'of FIG. 5, the function is substantially the same as the timing switch 7 of FIG.

The function of the timing switch 7 'described above is merely described as an example, and various operating time schedules will be possible if a proper circuit is configured by combining a plurality of timers and switches. In addition, since the configuration of such a circuit can be easily performed in the technical field according to a required function, a detailed description of the circuit configuration is omitted.

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

The device 1 of the present invention is provided with both hooks 43 and 43 of the rope 5 on a ring 69 provided at the lower end of the vertical door frame (Doors 65) on both sides of the sliding door or at both ends of the doors 67. '), And the rope traction device 3 is installed by assembling the lower horizontal door frame 73 of the inner door 71 to the bracket 39 attached with the screw 37 at the center. At this time, the rope 5 is wound around the spool 45 formed on the hook 43 of the rope 5 to adjust the length of the rope 5 to fit the length between the two rings 69 to make the rope taut.

When the device is installed using the above-described prefabricated bracket 101, the prefabricated bracket 101 is assembled to the vertical door frame 77 of the inner door 71, and the hook 43 is the vertical door frame on both sides of the sliding door. It can be installed by nailing the nail 69 instead of the ring 69 in an inconspicuous part (part not affecting the aesthetics) between the 65 and the wall.

When the device 1 of the present invention is installed in the sliding door, the plug 61 of the electric wire 49 is inserted into the outlet 75, and the time when the door is closed on the timer 51 for a long time (the temperature is dropped and the sliding door is opened) Close time; start time of the device), and then set the operation duration of the device in the short-time timer 53. Then, the rotation direction of the motor is set by the selector switch 19 so that the reversible motor 9 of the present apparatus rotates toward the closing door, and the on-off switch 55 is turned on.

When the apparatus 1 is installed and sleeps in this state with the sliding door open, the power is supplied at the scheduled time so that the motor 9 of the rope traction apparatus 3 rotates, thereby following the rope 5. The rope towing device 3 is forced to move to the right and eventually closes the inner door 71 that is constrained to the rope towing device. When the input operation duration elapses, the power is cut off and the operation of the device 1 is stopped. Therefore, when the device of the present invention is installed in the above-described manner in a hot weather at night and a cold weather at dawn, the door is open at night so that the user can sleep in a cool state, and the door is closed at dawn, so there is a risk of catching a cold. There will be no.

It may occur that the motor 9 continues to operate when the sliding door is already closed by inputting the operation duration too long, but the sliding door may be inserted between the rope 5 and the pulleys 11, 13, 13 '. Since more than the force required to open and close (the friction force established between the rope and the pulleys) is applied, the pulleys 11, 13 and 13 'are unable to tow the rope 5 and are tumbling and continue to operate. The motor 9 stops over time so that the device is not damaged. If the device is operated while an obstacle is placed on the rail of the sliding door or the door cannot be opened or closed due to moisture or the like, the rope 5 will stop in the pulleys for a short period of time, and thus the device will be damaged. Or door departure does not occur. On the other hand, when opening a sliding door, it can operate similarly to closing a door except setting the rotation direction of the reversible motor 9 of the said rope traction apparatus 3 reversely.

Opening the sliding door with the automatic sliding door opening and closing device 1 of the present invention using the timer switch 7 can be operated in conjunction with the operation of the air conditioner. That is, when the air conditioner 59 is operating, the power supply is cut off, and when the air conditioner 59 is stopped, the cone center 63 configured to supply power is included in the circuit of the air conditioner, and the plug of the apparatus 1 is connected. (61) is connected to the said outlet (63). Then, when the operation start time of the long time timer 31 is set to zero (0) and the operation duration time required for the short time timer 35 is input, the time input to the timer (not shown) of the air conditioner itself is elapsed. The moment the air conditioner stops, the device 1 can be operated to open the sliding door. Therefore, while the air conditioner is operating, it is possible to maximize the cooling effect of the air conditioner by closing the door, and after the air conditioner is stopped, the door can be opened to cool down.

Next, a process of repeatedly opening and closing the sliding door using the timer switch 7 'of FIG. 5 to periodically ventilate the air conditioner during operation will be described. As shown in FIG. 7, the device 1 of the present invention is installed in a sliding door in the same manner as described with reference to FIG. 6. FIG. 7 illustrates a state in which the rope traction device 3 is installed in the vertical door frame 77 using the assembly bracket 101. In the state where the plug 61 of the electric wire 49 is inserted into the outlet 75, the mode switching switch 151 is selected as the opening and closing repeating mode 153, and then, for example, the opening and closing interval setting timer 161 is selected. After inputting 1 hour into 5 minutes into the closing time setting timer 163, 5 minutes into the time setting timer 159, and 1 minute into the operation duration setting timer 165, the on-off switch 167 Turn on. Accordingly, power is supplied to the motor 9 of the rope traction device 3 after 1 hour to be rotated forward (or reverse), and the sliding door 71 is opened, and after 1 minute (after the door is completely open), the power is cut off. The operation of the device 3 is stopped, and again 5 minutes later, the power is supplied with the opposite polarity, the motor is reversed (or forward), and the sliding door 71 is closed, and after 1 minute (after the door is completely closed). The power is cut off and the operation of the device 3 is stopped. The opening / closing action of the sliding door is repeated at a time of 1 hour until 5 o'clock, and finally, the sliding door 71 is opened.
