Description

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. 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 a 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 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 dawn and close the door, because you can sleep in the heat when you close the window in preparation for the dawn at bedtime. It is common to sleep at an open door. However, in the early hours of deep sleep, people often go to bed without closing the window and have a cold.

In the mid-summer tropical nights, when the weather is hot all night and the temperature drops slightly at dawn, sleeping on the air conditioner until dawn is not only economically expensive because it is exposed to the cold wind of the air conditioner for a long time, but also increases the power consumption. However, just keeping windows open without using air conditioners can't cool 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 in order to increase the efficiency of the air conditioner in the hot summer, the air conditioner needs to be operated continuously and the air conditioner needs to be ventilated from time to time to keep the room comfortable and prevent air conditioners. have. But it is easy to forget to get up and close the windows from time to time, and forget about them.

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 automatically open or close a room temperature in a hot summer season when an air conditioner is running or during a busy season, when a sliding door which is widely used as a window or a living room door is pre-booked. 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.

An object of the present invention, the reversible drive motor, the gear rotated by the motor, and when the torque load of a predetermined value or more acts on the gear block the transmission of the rotational force of the motor to the gear so that the gear shaft of the motor The rack along a door frame of the sliding door, comprising a gear drive comprising a safety device for turning against the gear, a rack meshing with the gear of the gear drive, and a timer switch to which an operation schedule of the motor is input. It is achieved by a removable sliding door automatic opening and closing device, characterized in that the gear is installed to engage the rack by fixing the gear drive to the sliding door door frame to be opened and closed.

The safety device may include a first compression plate which is integrally rotated to the gear inserted into the rotation shaft of the motor in an integral manner, the second compression plate fixed to the rotation shaft of the motor and integrally rotated to contact the first compression plate; And a compression spring for compressing and frictionally contacting the first compression plate and the second compression plate, and the gear is rotated by the rotational force of the motor by frictional contact between the two compression plates by the compression spring, The first pressing plate and the second pressing plate are slid when the torque load of a predetermined value exceeding the pressing force acts on the gear, so that the gear swings about the rotational axis 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 present invention and do not limit the scope of the present invention.

1 is a view showing a removable sliding door automatic opening and closing device according to the present invention, a perspective view of the back of the casing is removed, Figure 2 is a sectional view of the gear drive, Figure 3 is a perspective view showing an example of the safety device.

As shown, the removable sliding door automatic opening and closing device 1 of the present invention basically includes a gear drive 3, a rack 5, and a timer switch 7.

The gear drive device 3 has a configuration in which the reversible drive motor 9, the gear 11, and the safety device 13 are installed in the casing 15, and provide a power to open and close the sliding door, which will be described later. As described above, the casing 15 is attached to the sliding door by fixing the casing 15 to the door frame of the inner sliding door.

Although the casing 15 may be directly fixed to the door frame of the inner sliding door with a screw or the like, a fastener is formed on the casing 15 and a bracket is attached to the door frame, so that the fastener is fitted to the bracket to be assembled. It is preferable in that the apparatus 1 of the invention can be easily separated when not in use.

4 is a perspective view showing an example of a fastener for fixing the casing to the door frame, and FIG. 5 is a front view of the casing fixed to the door frame of the sliding door by the fastener of FIG. As shown, a plate-shaped fastener 17 is formed at one side of the casing 15, and the bracket 19 is screwed to the door frame 67, and the fastener between the door frame 67 is provided. The c-shaped bent portion 21 is formed so that the insertion hole into which the 17 can be inserted is formed. Therefore, when the fixture 17 is inserted into the insertion hole formed between the bracket 19 and the door frame 67 while the bracket 19 is attached to the door frame 67, the casing 15 is installed on the sliding door. do. At this time, in order to prevent the fastener 17 from being easily detached from the bracket 19, the locking groove 23 is formed in the bracket 19, and the locking jaw 25 is formed in the fastener 17 at the corresponding position. It is preferable.

In the case where the bracket 19 is used to fix the casing 15 to the door frame 67, the bracket 19 is attached to the door frame 67 by screws or the like. It is not easy, and after separation, nail marks remain on the door frame 67, which causes damage to the sliding doors, thereby damaging the aesthetics. Therefore, it is preferable to use the prefabricated bracket 101 which does not leave nail marks as a bracket used when installing the casing 15 to the door frame 67.

Fig. 6 is a perspective view of the assembled bracket, and Fig. 7 is a front view of the assembled bracket of Fig. 6 installed on the 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 67 of the sliding door made of wood or aluminum. A mounting table fixing screw 107 is provided to fix 103 to the vertical door frame 67, and the slit 113 on the other side 109 to be fixed by adjusting the position in the thickness direction of the vertical door frame 67. ) -Shaped subsidiary stand 111 is fastened by the subsidiary fixing screw 115. In addition, the lower side of the other side 109 is extended, and the bracket 117 is provided with an insertion opening 119 into which the fastener 17 formed in the casing 15 is inserted. Of course, in the bracket 117, it is preferable to form the locking groove 121 at a position corresponding to the locking step 25 of the fixing member 17 so that the fixing member 17 is not easily separated from the insertion hole 119. 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 123 of the base 103, and inserted into the vertical door frame 67 of the sliding door, and then tighten the assembly table fixing screw 107 to vertically mount the assembly table 103. After fixing to the door frame 67, the support 111 is as close as possible toward the center side 123, and by tightening the support fixing screw 115, it is firmly fixed to the vertical door frame 67. 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.

The reversible drive motor 9 is a sanctually rotatable motor that can selectively rotate the gear 11 clockwise or counterclockwise. The reversible drive motor 9 to be used is not particularly limited, but the use of a small reversible deceleration motor with a low 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 in that it exists. In Fig. 1, reference numeral 27 denotes a selection switch for selecting the rotation direction of the reversible drive motor 9, and this selection switch 27 may be provided in the timer switch 7 without being installed in the motor 9.

The gear 11 is inserted in the rotation shaft 29 of the drive motor 9. The gear 11 is fixed to the rotary shaft 29 of the motor 9 and is not directly rotated by the motor 9, but indirectly through the safety device 13 which will be described in detail later. That is, the gear 11 is inserted so that the gear 11 can be idling with respect to the rotation shaft 29 without being tightly fixed to the rotation shaft 29 of the motor 9. To this end, the shaft insertion hole of the gear 11 is formed slightly larger than the rotation shaft 29 of the motor 9. As a result, the rotating shaft 29 of the motor has a function of supporting the gear 11 to be held in place in the casing 15 while providing rotational force indirectly to the gear 11.

The rotational force transmission between the rotary shaft 29 of the motor 9 and the gear 11 is made through the safety device 13. The safety device 13 prevents the rotational force of the motor 9 from being transmitted to the gear 11 when a torque load greater than or equal to a predetermined value is applied to the gear 11 so that the rotational shaft 29 of the motor with respect to the gear 11 is applied. It is a device which prevents an excessive load on a motor by making it futile.

The rotation speed of the motor 9 and the operation of the timer switch 7 are precise, and the time input to the timer switch 7 is accurate so that the motor stops at the moment when the sliding door is fully opened or closed, and the door frame rail of the sliding door If there is no obstacle or the condition that the sliding door cannot be opened or closed by the force of the motor only due to the influence of moisture or the like does not occur, the gear 11 is rotated by receiving the rotational force directly from the rotating shaft 29 of the motor without a safety device. It may be configured. However, in reality, it is not certain that the above situation will not occur, and in the absence of a safety device, the motor will continue to operate in a state in which the door cannot be moved, so that the seam motor is overloaded and the apparatus of the present invention is damaged. Or sliding doors from the rail cannot be completely excluded.

Therefore, in the sliding door opening and closing device 1 according to the present invention, even after the sliding door is completely opened or closed, the motor continues to rotate to overload the motor, or a situation in which the sliding door cannot be opened or closed by the power of the motor. In case the safety device 13 is included.

As the safety device 13 used in the present invention, when the torque load acting on the gear 11 is equal to or greater than a predetermined value, the rotational force 29 of the motor is blocked by preventing the rotational force of the motor 9 from being transmitted to the gear 11. There is no particular limitation as long as it has a function of turning against the gear 11.

1 to 3 show an example in which two pressing plates 31 and 33 and a pressing spring 35 are used as the safety device 13. As mentioned above, the gear 11 is installed in an inclined manner with respect to the rotating shaft 29 of the motor, and the first compression plate 31 is formed to be integrally rotated. The second pressing plate 33 is fixed to the rotating shaft 29 of the motor by the fixing pin 37, so that the rotating shaft 29 of the motor rotates integrally with the rotating shaft 29 of the motor. The first pressing plate 31 and the second pressing plate 33 are in contact with each other, and the two pressing plates are pressed by the elasticity of the pressing spring 35 and are in friction contact with each other.

Therefore, the gear 11 is not directly rotated by the rotational shaft 29 of the motor, but is rotated by frictional contact by the compression spring 35 of the second compression plate 33 and the first compression plate 31. do. However, when a torque load of a predetermined value or more exceeding the pressing force of the pressing spring 35 acts on the gear 11, the first pressing plate 31 and the second pressing plate 33 slide with each other, resulting in a rotational shaft of the motor. The 29 is turned against the gear 11 so that only the motor 9 and the second pressing plate 33 are turned, and the gear 11 and the first pressing plate 31 do not turn. Therefore, even if a torque load of a predetermined value exceeding the pressing force of the crimping spring 35 acts on the gear, there is no fear that the motor 9 will be overloaded and the device will be damaged.

It is preferable that the contact surfaces of the first pressing plate 31 and the second pressing plate 33 in contact with each other be formed to have a high coefficient of friction so as to be in contact with the widest possible area so that sufficient frictional resistance can be received. The crimping spring 35 prevents the first crimping plate 31 and the second crimping plate 33 from slipping on each other with respect to the torque load exerted on the gear 11 when the sliding door is normally opened and closed. When the gear 11 is applied to the gear 11, the first pressing plate 31 and the second pressing plate 33 are pushed together so that the first pressing plate 31 and the second pressing plate 33 are inward from each other. It is elastic enough to pressurize.

Fig. 3 shows an example of the pressing spring 35 composed of two members in which a plurality of claws 41 are formed in the semi-circular elastic band steel 39. Figs. The crimping spring 35 is provided by contacting the first crimping plate 31 and the second crimping plate 33 and then pressing the two members on the upper, lower, left, and right sides. At least one of the two pressing plates 31 and 33 is formed with a jaw 43 at the circumferential end of the non-contacting surface so that the claw 41 of the pressing spring 35 is caught, so that the pressing spring 35 is It is desirable not to leave easily.

1 to 3, an example in which the second pressing plate 33 is fixed to the rotary shaft 29 near the motor 9 side and the second pressing plate 33 is positioned between the motor 9 and the gear 11 is shown. Although shown, the second pressing plate is fixed to the end of the rotary shaft 29 of the motor and configured so that the gear 11 with the first pressing plate 31 is provided between the second pressing plate 33 and the motor (9). It is also possible.

At the bottom of the casing 15 is a rack 5, which is directly engaged with the gear 11 protruding from the casing 15 or with the relay gear 47. The rack 5 is fixedly attached to the upper surface of the lower door frame (door fat) 63 of the sliding door with a sufficient length to cover the movement trajectory of the gear drive 3 attached to the inner sliding door 65. The rack 5 can be fixed by nailing both ends of the rack 5 to the door frame 63 or by using double-sided tape. When the device of the present invention is not in use, the pin 45 is installed in the door frame 63 so that the rack 5 can be easily removed without damage, and the rack 5 is fixed to the pin 45 by hanging. It may be.

The relay gear 47 is located between the gear 11 and the rack 5. That is, as shown in Figs. 1 to 3, the gear 11 is completely accommodated in the casing 15, and the relay gear 47, which meshes with the gear 11 and rotates, is lowered into the casing 15. Protruding, the relay gear 47 meshes with the rack 5 to transmit the rotational force of the gear 11 to the rack 5. At this time, if the gear 11 inserted into the rotary shaft 29 uses a relatively small gear and the relay gear 47 uses a relatively large gear to increase the gear ratio, the motor having a relatively low output power in the apparatus of the present invention is used. Can be used. In Figs. 1 and 3, reference numeral 49 denotes an axis for rotatably fixing the relay gear 47 to the casing 15.

Therefore, when the gear 11 rotates by the motor 9, the casing 15 containing the gear drive device 3 opens the rack 5 by the action of the relay gear 47 and the rack 5. Therefore, the linear movement to the left or right. That is, the rotation of the motor 9 is converted to linear motion through the relay gear 47 and the rack 5 and used for opening and closing of the sliding door.

In the above description, the relay gear 47 engaged with the gear 11 is rotated by being bitten by the rack 5, but the relay gear 47 is omitted and the gear 11 is formed to protrude out of the casing 15. It will also be possible for the 11 to snap directly to the rack 5.

The wire 51 for supplying power to the reversible drive motor 9 is provided with a timer switch 7 for inputting an operation schedule of the motor 9. As the timer switch, 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 Figs. 8 and 9 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 start time of supplying current by connecting a contact of a switch after a long time elapsed, which generally ranges from tens of minutes to several hours, and generally opens and closes a sliding door. It is a timer switch that allows you to enter the duration of operation to stop the C-Motor by closing the current by opening the contact after a short time of several tens of seconds.

For example, a long time timer 53 for inputting a long time (operation start time), a short time timer 55 for inputting a short time (operation duration), and an on-off switch 57 are provided in one switch box ( The timer switch 7 installed in 59 can be used. The on-off switch 57 is a main switch for regulating the current in the motor 9. As mentioned above, the timer switch 7 may be provided with a selection switch for selecting the rotation direction of the reversible drive motor 9.

The timer switch 7 'shown in Fig. 8 not only opens and closes the sliding door according to the sliding door opening and 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. 8, 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, 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 In the opening / closing interval setting timer 161 for inputting a time interval between each sliding door opening and closing operation, and when the opening / closing repeat mode 153 is selected in the mode switching switch 151, the door is opened until the door is closed again. Closing time to enter time Positive timer 163, the operation duration setting timer 165 which inputs the operation duration time which power is supplied to the motor 9, and a sliding door opens and closes, and the main ON- which controls an electric current to the motor 9; The timer switch 7 '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 9 periodically (for example, every hour), and opening and closing of the sliding door is performed 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, for example, to input a time interval, such as 10 minutes, 30 minutes, 1 hour, 2 hours, etc. For example, when 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 motor 9 every hour. The door will open.

Once the power is supplied and started, the motor 9 should be stopped by stopping the power when the door is fully opened. The time until the started motor is stopped, that is, the operation duration time, is the operation duration setting timer described above. Enter (165). The duration of operation depends on the size and weight of the sliding door, the power and the 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 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 in consideration of various factors such as the temperature difference between the indoor and the outdoor, the wind speed, and the size of the interior. Therefore, each time the sliding door is opened by the opening / closing repeat mode 153, the open door is closed after the time (1 minute, 2 minutes, 5 minutes, 10 minutes, etc.) input to the closing time setting timer 163.

The motor 9 once actuated to close the door must be stopped at the point when the door is fully closed, and the time until the motor once actuated is stopped, i.e. the duration of operation described above, as with the previous door opening, 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 opening mode 155 and the closing 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 opening / closing interval setting timer 161 and the closing time setting timer ( 163 does not operate, only the time setting timer 159 and the operation duration setting timer 165 operate. 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, the power is supplied to the motor 9 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 9 is stopped. When the open mode 155 or the closed mode 157 is selected in the timing switch 7 'in FIG. 8, the function is substantially the same as the timing switch 7 in FIG.

Also, in the above-described timer switch 7 ', the time interval between each sliding door opening and closing operation, which is applied only when the opening / closing repetition mode 153 is selected in the mode switching switch 151, may be closed again after opening the door. The time until it is fixedly set in the circuit of the timer switch to a constant value suitable for ventilating the room where the air conditioner is operating will not have four major obstacles for the apparatus of the present invention to perform its function. Thus, as shown in Fig. 9, 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. It is also possible to use a timer switch 7 'without the opening and closing interval setting timer 161 and the closing time setting timer 163.

The timing switches 7, 7 ′, 7 ′ described above have been described as an example, and when a circuit is directly formed by combining a plurality of timers and switches, various operating time schedules of the apparatus are input. A timer switch may be provided. Since the circuit configuration of the timer switch can be easily performed in the technical field according to the required function, the detailed circuit configuration will be omitted.

10 and 11, the process of opening and closing the sliding door by the apparatus of the present invention will be described. First, a process of opening the sliding door using the timer switch of FIG. 1 will be described with reference to FIG. 10.

In the removable sliding door automatic opening and closing device 1 according to the present invention, the rack 5 is attached to the upper surface of the lower frame (door fat) 63 of the sliding door 61, and the gear driving device 3 is attached to the rack 5. (11) by fixing the casing (15) using the bracket (19) or the prefabricated bracket (101) described above on the door frame (67) of the inner sliding door (65) at the position where the relay gear (47) of the floating gear snaps. It is installed in the sliding door (61).

When the apparatus 1 of the present invention is installed in the sliding door 61, the plug 69 of the electric wire 51 is inserted into the outlet 71, and the time to open the door 65 in the timer 53 for a long time ( The start time of the device) and set the operation duration of the motor 9 to the short time timer 55.

The operation duration of the motor 9 is appropriately selected in consideration of the size of the sliding door 61, the rotational speed of the motor 9, and the like. Then, after the reversible drive motor 9 sets the rotational direction of the motor 9 by the selector switch 27 so as to rotate toward the opening door, the on-off switch 57 is turned on.

When the main unit 1 is installed and sleeps in the state where the inner sliding door 65 is closed in this way, power is supplied to the motor 9 at the scheduled time and the relay gear engaged with the gear 11 or the gear 11 ( The casing 15 moves along the rack 5 by the action of 47 and the rack 5, which eventually opens the inner sliding door 65 constrained by the casing 15. When the motor 9 is operating even when the door is open, or when there is an obstacle in the rail of the door frame 63 and the door cannot be negative, and a tog load of a predetermined value or more is applied to the gear 11, two compressions are applied. Since the plates 31 and 33 slide with each other and the motor 9 rotates, the gear 11 does not rotate (the relay gear does not rotate either), so that the device is not damaged or the door is detached. The motor 9 stops when the operation duration time input to the short time timer 55 elapses. Closing the sliding door can be operated in the same manner as opening the sliding door except setting the rotational direction of the reversible drive motor 9 in reverse.

Opening the sliding door with the automatic door opening and closing device 1 of the present invention can be operated in conjunction with the operation of the air conditioner. That is, as shown in Fig. 10, when the air conditioner 73 is operating, the power supply is cut off, and when the air conditioner 73 is stopped, the outlet 75 configured to supply power is included in the circuit of the air conditioner 73. Then, the plug 69 of the apparatus 1 is connected to the outlet 75. Then, if the operation start time of the long time timer 53 is set to zero (0) and the operation duration time required for the short time timer 55 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 inner sliding door 65. Therefore, while the air conditioner is in operation, the door can be closed to maximize the cooling effect of the air conditioner. 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. 9 to periodically ventilate the air conditioner during operation will be described. As shown in FIG. 11, the apparatus 1 of the present invention is installed in the sliding door 61 in the same manner as described with reference to FIG.
