A sliding door automatic opening and closing device for opening or closing a door.

(Prior Art)

In order to keep the room in a comfortable state, opening and closing windows and living room doors to ventilate the room air and control the temperature is a common practice in daily life. In regions where the four seasons have a distinct climate, the temperature is hot enough to reach 25 ° C at night in the summer, but cool enough to feel cool at late night or dawn, while in the autumn, it is cool at night. Although it maintains a moderate temperature, it is often the case that there is a sharp crossover when the temperature drops chilly at dawn.

As a way to cope with such sudden changes in temperature in a normal residential life, open windows, living room doors, etc. when the temperature is high, or operate a cooling device such as an air conditioner to lower the indoor temperature, and close or close the door when the temperature drops. It is common to stop the instrument.

Opening and closing doors is not uncomfortable during daytime activities, but getting up and closing doors while going to bed is quite inconvenient and cumbersome. For example, in the case of typical weather in the early autumn, when the temperature at night is hot and the temperature at dawn is cold, sleeping close to the window to prepare for the dawn at bedtime may cause you to sleep very hot. It is common to sleep in the open, but it is common to injure one's health, such as catching a cold, by not going to close the window at dawn, which is the time of deep sleep.

Also, in the case of a typical tropical night in midsummer, where the temperature stays warm overnight and the temperature drops slightly at dawn, sleeping on the air conditioner until dawn not only exposes you to the cold air of the air conditioner for a long time, but also increases the risk of cooling disease and increases the power consumption. However, it is difficult to get a good night's sleep on a hot summer night just by opening the window without using the air conditioner, so adjust the timer to stop the air conditioner at two or three o'clock in the evening when the temperature drops, and close the window to increase the efficiency of the air conditioner. Sometimes I go to bed. In this midsummer weather, even if it's about two or three nights, the windows are closed and the temperature is high enough for you to sleep. However, it is inconvenient to get up at bedtime and open the window.

Accordingly, an object of the present invention is to maintain a comfortable indoor temperature by automatically opening or closing a sliding door widely used as a window or a living room door in advance during bedtime during a hot summer season or a severely crossed season. It is to provide a sliding door automatic opening and closing device that can ventilate. Especially, it is used as a table clock in ordinary times, and when necessary, it is installed on a sliding door and uses a sliding door opening and closing time setting means built in a table clock with a timer function. It is to provide a sliding door automatic opening and closing device that can open and close the sliding door at a scheduled time.

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

First, referring to Figures 1 to 3, a sliding door automatic opening and closing device using a spring as a drive source for opening and closing the sliding door will be described. 1 is a schematic cross-sectional view of an example using a spring as an automatic sliding door opening and closing device according to the present invention, FIG. 2 is an internal configuration diagram of a sliding door opening and closing device of FIG. 1, and FIG. 3 is an exploded view of the rotating body of FIG.

As shown in Fig. 1, the sliding door automatic opening and closing device 1 of the present embodiment includes a sliding door opening and closing device part 3 and a table clock part 5 having a timer function. The sliding door opener / closer 3 and the table clock 5 may be installed in a single casing, but the sliding door opener / closer 3 and the table clock 5 may be provided in separate casings 7 and 9, respectively. By installing and combining the two casings 7 and 9 with the hinge 11 so that they can be folded, usually by combining the two casings 7 and 9 with the hinge 11 to be folded, the two casings 7 are normally , 9) fold at a predetermined angle to use the sliding door opener (3) as a pedestal of the table clock (5) as a clock, and when used as a sliding door opener, the two casings can be completely folded to be installed on the sliding door. It is desirable to.

As shown in FIGS. 1 and 2, the sliding door opening and closing unit 3 includes the main winding 13, the rotating body 15, the braking means 17, the operating lever 19, the solenoid stopper 21, It consists of a configuration including a shut-off switch 23, the towing rope 25, and the installation port (27).

The spring 13 is a means for supplying the power necessary to open and close the sliding door, and a helical spring of a strip steel can be used. The spring 13 is provided in the space formed by the failure body rotating body 15 and the casing 7. The rotating body 15 is rotatably installed in the casing 7 by inserting the shaft 29 formed in the center thereof into the shaft hole 31 formed in the casing 7 (see Fig. 3). One end of the mainspring 13 is fixed to the shaft hole 31 and the other end is fixed to the rotating body 15. Therefore, when the rotating body 15 is rotated, the mainspring 13 is wound around the shaft hole 31, and the elastic force is accumulated, and the spring 13 is released while rotating the rotating body 15 in the opposite direction by the elastic force. Rope winding drum 33 is formed on the circumferential surface of the rotating body 15, the rope can be wound, so that the traction rope 25 is wound or unwinded as the rotating body 15 rotates.

The rotating body 15 is provided with braking means 17 for selectively braking the rotation. The braking means 17 is not particularly limited as long as it can selectively brake the rotating body 15. An example using the braking rope 17 'and the spring 17 is shown in the embodiments of FIGS. have. As shown, the braking means 17 has one end of the braking rope 17 'fixed to the fixing pin 35 of the casing 7 and parallel to the rope winding drum 33 of the rotating body 15. After winding 2-3 times on the braking drum 37, the other end is connected to the spring 17, and the spring 17 is again fixed to the fixing pin 39 of the casing 7. Therefore, when the spring 17 pulls the brake rope 17 'and the brake rope 17' is tightly wound around the rotor 15, the rotor 15 cannot be rotated, on the contrary, the spring 17 When the brake rope 17 'is loosened and the brake rope 17' is loosely wound around the rotor 15, the rotor 15 may be rotated.

In this embodiment, an example in which the braking rope 17 'and the spring 17 are used as the braking means 17 is shown. Instead of the rope, a high friction rubber band is used alone or in combination with the spring. The rotor 15 may be selectively braked by friction between the brake drum 37 and the brake drum 37 of the rotor 15.

The selective braking of the rotating body 15 by the braking means 17 includes an actuating lever 19 for selectively holding the braking state of the braking means 17 and braking of the braking means 17 when power is supplied. It is made by the solenoid stopper 21 which moves the actuating lever 19 to release the state.

In this embodiment in which the braking means 17 consists of a braking rope 17 'and a spring 17, the actuating lever 19 and the solenoid stopper 21 act to hold or relax the spring 17 in a pulled state. Do it. The solenoid stopper 21 is provided with a stopper 41 which is installed in the casing 7 in proximity to the spring 17 and moves when power is supplied. At the inner end of the stopper 41, the actuating lever 19 is located in a straight line. As shown in Fig. 2, the actuating lever 19 has a substantially U-shape made of a material such as elastic plastic, and has a catching jaw 45 caught by the catching protrusion 43 formed on the casing 7, An operating handle 47 is provided which protrudes out of the casing 7 so that the position of the operating lever 19 can be displaced by hand. The locking jaw 45 is always pressurized toward the engaging projection 43 by the elasticity of the portion of the operating lever 19 in which it is formed. In addition, the actuating lever 19 is provided with a protruding pin 48 fitted into the spring 17 of the braking means 17. When the actuating lever 19 is moved left and right, the spring 17 of the braking means 17 is moved. Is pulled or relaxed. That is, in the state in which the locking jaw 45 of the operating lever 19 is caught by the locking protrusion 43, the spring 17 is pulled to keep the braking rope 17 'tight and the locking jaw of the operating lever 19 When 45 is released from the locking projection 43, the operating lever 19 moves in the direction of the arrow in FIG. 2 by the elasticity of the spring 17, thereby loosening the spring 17 to keep the brake rope 17 'loose. .

On the other hand, the stopper 41 and the operating lever 19 are formed in the inclined surface corresponding to the end facing each other, so when the stopper 41 pushes the operating lever 19, the two inclined surfaces are staggered with each other, the locking step 45 The actuating lever 19 is deformed to be released from the locking projection 43.

Preferably, at the position close to the actuating lever 19, a cutoff switch 23 for cutting off the power supplied to the solenoid stopper 21 is provided. The disconnect switch 23 is composed of a fixed terminal 49 fixed to the casing 7 and a movable terminal 51 of elasticity, and the movable terminal 51 is fixed terminal (when external force is not acted on by its elasticity). 49) away. In this case, a pressure plate 53 is attached to the end of the operation lever 19 facing the shutoff switch 23 to press the movable terminal 51 toward the fixed terminal 49 to connect the contacts. As shown in FIG. 2, the pressing plate 53 forms a sloped surface of the movable terminal 51 so that the movable jaw 45 is caught by the engaging projection 43. Press toward the fixed terminal (49).

A towing rope 25 is wound around the rope winding drum 33 of the rotating body 15. That is, one end of the towing rope 25 is fixed to the rope winding drum 33 and extends through the guide hole 55 formed in the casing (7), and the other end is attached to the hook 57 for hanging on the sliding door. have. The tow rope 25 is wound around the rope winding drum 33 when the spring 13 is completely released and does not accumulate the elastic force. When the spring 13 is wound and the elastic force is accumulated, the rope winding drum 33 It is wound around the drum 33 so that it may be in the state loosened. Therefore, when pulling the tow rope 25 by hand, the tow rope 25 is released from the drum 33, and the spring 13 is wound, and the elastic force is accumulated, and when the tow rope 25 is released in this state, the spring 13 is pulled out. The tow rope 25 is wound around the rope winding drum 33.

Towing rope 25 may be provided with a stopper 59 that can adjust the length of the towing. 4 to 6 show examples of stoppers installed in the towing rope. First, as shown in Figs. 4 and 5, as the stuffing 59, two plates 61 and 63 fitted to the towing rope 25 can be used. In other words, the rope is inserted into a plate 61 having two holes 65 and 65 'into which the rope is fitted and a plate 63 having one hole 67 into which the rope is fitted. ), And then to the hole 67 of the plate (63), and then to another hole (65 ') of the plate 61 can be installed in the pull rope (25) to be used as a stopper (59). Therefore, when the two plates (61, 63) are placed in the proper position of the towing rope (25), the stopper (59) is caught in the guide hole (55) of the casing (7) when the towing rope (25) is pulled out. 25) is not towed. The holes 65, 65 ', 67 formed in the two plates 61, 63 are largely formed to move freely along the towing rope 25, but when the rope 25 is pulled, the two plates 61, 63 As shown in Fig. 4, the towing rope 25 is towed only to the place where the stopper 59 is located because it is fixed at a predetermined position of the rope.

As the stopper 59, a stopper 59 'as shown in Fig. 6 can also be used. That is, to the stopper 59 'made of a plate 61' formed with one hole 65 into which the rope 25 is fitted and a plate 63 'formed with one hole 67' into which the rope is fitted, To the hole 65 of the plate 61 'and into the hole 65 of the plate 61 and then to the hole 65 of the plate 61 again. Can be.

The mounting fixture 27 has a function of installing the apparatus 1 of the present invention on a sliding door, and a hook or a rope may be used. For example, an installation rope 27 may be used, one end of which is fixed to the casing 7 and the other end of which has a sliding door 58 or a hook 58 that can be hung on the wall.

Hereinafter, with reference to FIG. 1, the table clock part 5 of the timer function which sets the operation time of the spring-type sliding door opening / closing apparatus 1 is demonstrated. As described above, the table clock part 5 is substantially similar to a conventional clock widely used by batteries, and includes a sliding door opening / closing time setting means 71. The opening / closing time setting means 71 connects the switch contact at the set time to operate the solenoid stopper 21 of the sliding door opening / closing unit 3 instead of the sound generating unit in the alarm time setting means of the conventional alarm clock to operate the sound generating unit. It is configured to connect. That is, the opening / closing time setting means 71 includes an opening / closing time setting needle 73 for setting the opening / closing time of the sliding door, and a switch contact 77 intermittent according to the relative positions of the opening / closing time setting needle 73 and the hour hand 75. It consists of a configuration, including the time alignment and the opening and closing time setting of the table clock portion 5 is made by the time adjustment screw 79 and the opening and closing time adjustment screw 81 on the back of the casing (9). Except for the above-described difference, the table clock part 5 is the same as the structure and circuit of a general alarm clock, and thus a detailed description thereof will be omitted.

In addition, when using a table clock having an alarm function in the present invention, the switch contact 77 of the opening and closing time setting means 71 is the battery 83, the sound generating unit (not shown) and the battery 83 of the alarm device; ) And the solenoid stopper 21 to be intermittent, and the on / off time setting means 71 cuts off all the power to the alarm device and the solenoid stopper 21, an alarm mode to supply power only to the alarm device. If the solenoid stopper 21 is provided with a mode switching switch having a sliding door opening / closing mode for supplying power only, it is selected as the off mode when only the watch is to be used without using both the alarm function and the sliding door opening and closing function. If you want to use it as a clock with alarm function, select the alarm mode, and if you want to use it for sliding door opening and closing, you can select the sliding door opening and closing mode. Can be.

In addition, as mentioned above, a general timer may be used instead of the desk clock of the timer function. In this case, the sliding door opening and closing time setting means 71 and the switch contact 77 are built in a timer, and are configured to supply power to the solenoid stopper 21 by connecting the switch contact 77 at a set time. .

Hereinafter, an operation of opening and closing the sliding door by the spring-type sliding door opening and closing device 1 described above with reference to FIGS. 1, 2 and 7 will be described. 7 is a state diagram used in the automatic door opening and closing device of FIG.

The device 1 is a suitable position of the inner door 87 to open and close the sliding door 85, for example, the inner door by pulling the towing rope 25 by hand as appropriate to the size of the sliding door 85 The hook 57 of the towing rope 25 is hooked to a hook attached to a hook or an inner door locking device, and the hook 27 is mounted on a wall or a door post opposite to the inner door 87. Then, the opening and closing time setting needle 73 of the opening and closing time setting means 71 is set at the time to open the sliding door by operating the adjusting screw 81 on the back of the table clock part 5.

If the inner door 87 does not have a suitable hook for hanging the hook 57 of the towing rope 25, the removable auxiliary ring 90 as shown in FIG. 89 can be used as a ring. As the auxiliary ring 90, an elastic plate having an approximately C-shape in which a ring 91 is formed may be used, and it may be used as a detachable window frame 89 having a predetermined range of thickness without damaging the window frame 89. .

In addition, when the mounting hole 27 is a rope, the wall or sliding door opposite to the inner door 87 must be nailed to hang the mounting rope 27, so that the wall or sliding door may be damaged by the nail. In order to prevent this from happening, a removable auxiliary ring 92 as shown in Fig. 9 can be installed on the rail 93 of the sliding door. The detachable auxiliary ring 92 includes a front plate 94 having a ring 95, a plurality of screw grooves 96, and a back plate 97 having a screw hole 98 inserted therein into a recess or outlet of the rail 93. It is a structure that can be fixed by tightening it with 99).

When the pulling rope 25 is pulled, the rotating body 15 rotates in the direction of the arrow in FIG. 2 and elasticity is stored in the mainspring 13. The braking rope 17 'of the braking means 17 acts only when the rotating body 15 rotates in the opposite direction of the arrow, and when the rotating body rotates in the direction of the arrow, the spring 17 extends and the braking rope 17' brakes. It is loosely wound around 37 so that the rotating body 15 can be rotated. When the pulling rope 25 is pulled by an appropriate length and then released, the rotating body 15 rotates in the opposite direction to the arrow by the elastic force stored in the mainspring 13, thereby causing a force to pull the pulling rope 25. However, if the operation lever 19 is pulled in the opposite direction of the arrow by hand, and the locking jaw 45 is held in such a state as to be caught by the locking protrusion 43, the brake rope 17 'is wound around the brake drum 37. And the spring 17 pulls the brake rope 17 'in the opposite direction to the arrow, the rotor 15 does not rotate and remains in a state in which the spring force 3 is stored.

As time passes, when the hour hand 75 reaches the position of the opening and closing time setting needle 73 of the opening and closing time setting means 71, the switch contact 77 is connected to allow current to flow from the battery 83 to the solenoid stopper 21. At this moment, the stopper 41 presses the operating lever 19 while moving in the direction of the arrow. Since the abutment surfaces of the actuating lever 19 and the stopper 41 are inclined, the actuating lever 19 is pushed down so that the catching jaw 45 is released from the catching protrusion 43, so that the actuating lever 19 is in the direction of the arrow. Will be moved to. By the movement of the operation lever 19, the spring 17 which is pulling the brake rope 117 'is relaxed, so that the braking force of the brake rope 7' which has braked the rotor 15 disappears. At the same time, the rotating body 15 rotates in the opposite direction to the arrow by the elastic force of the mainspring 13 to pull the towing rope 25, and the inner door 87 hanging on the towing rope 25 is opened.

The opening and closing of the inner door 87 is until the door is fully opened or closed until the stopper 59 installed in the aforementioned towing rope 25 is caught by the guide hole 55 of the casing 7 and is no longer towed. Is done.

On the other hand, when the operating lever 19 is moved in the direction of the arrow by the stopper 41, the pressing plate 53 formed on the operating lever 19 is separated from the movable terminal 51 of the disconnect switch 23, so that the movable terminal ( 51 is separated from the fixed terminal 49 by its elasticity, and thus can cut off unnecessary power supplied to the solenoid stopper 21, thereby minimizing the consumption of the battery 83 incorporated in the table clock part 5. have.

By the series of operations as described above, the sliding door can be opened and closed automatically as desired at a desired time. When the device 1 is to be used again next time, the pulling rope 25 is pulled out appropriately, and then the locking jaw 45 is pulled out by pulling the operating handle 47 of the operating lever 19 in the opposite direction to the arrow. And then reinstall and use it in the sequence described above.

Next, with reference to FIGS. 10-15, the sliding door automatic opening and closing apparatus using a motor as a drive means of a sliding door opening-closing apparatus part is demonstrated. Figure 10 is a front sectional view of an example using a motor as a sliding door automatic opening and closing device according to the present invention, Figure 11 is a side cross-sectional view of Figure 10, Figure 12 is an exploded view showing the rotation plate eccentric structure of the rope winding drum, Figure 13 10 is a schematic view showing the operation of the sliding door automatic opening and closing device of FIG. 10, FIG. 14 is a state diagram of the sliding door automatic opening and closing device of FIG. 10, and FIG. 15 is another state diagram of the sliding door automatic opening and closing device of FIG.

However, it is preferable to use a small speed reduction AC motor having a small rotational speed and a high power in that the sliding door can be opened and closed slowly and silently, and the sliding door automatic opening and closing device can be manufactured compactly at low weight.

The motor 103 is properly fixed to the casing 101, and a gear (105: hereinafter referred to as a small gear) having a relatively small diameter is provided on the rotating shaft 127 so that a rope winding for describing the power of the motor 103 will be described later. It mediates to the drum 107.

In the casing 101 adjacent to the small gear 105, the rope winding drum 107 is rotatably fitted to an axis parallel to the rotation axis 127 of the small gear 105 (drum shaft 111). That is, the rope winding drum 107 is formed integrally with the drum shaft 111 and does not rotate integrally, but the drum shaft 111 is inserted into the shaft hole 129 provided in the center of the rope winding drum 107 so that the drum The rope winding drum 107 is rotated about the shaft 111. The rope winding drum 107 has an air gear 109 selectively engaged with the small gear 105 to allow the rope winding drum 107 to rotate according to the rotation of the small gear 105. It is provided integrally with the branch. The selective engagement of the small gear 105 and the standby gear 109 will be described later.

The drum shaft 111 acts as a rotating shaft of the rope winding drum 107, and is capable of rotating itself in an eccentric manner. That is, the rotating plate 113 is attached to the both ends of the drum shaft 111 so as to be eccentric with respect to the drum shaft 111, and the pair of rotating plates 113 are disposed on both sides of the casing 101 than the rotating plates 113. The rotary shaft insertion hole 131 is formed to correspond to a slightly larger diameter, so that the position of the drum shaft 111 changes as the rotary plate 113 rotates in the rotary plate insertion hole 131.

In addition, a separation prevention plate 115 having a diameter larger than that of the insertion hole 131 is attached to the outer side of each rotating plate 113 to prevent the drum shaft 111 from being separated out of the casing 101. At least one of the release preventing plate 115 is detachably assembled to the rotating plate 113 so that the drum shaft 111 having the pair of rotating plates 113 can be installed so as not to cross the casing 101. It is. That is, the drum shaft 111 provided with the pair of rotating plates 113 is rotatably installed in the insertion hole 131 of the casing 101 by the pair of separation preventing plates 115. The reason why the drum shaft 111 is formed eccentrically on the rotating plate 113 will be described later.

On the other hand, one of the two release preventing plate 115 (the right release preventing plate in Figure 11) is formed so that the operating lever 117 is integrally extended, the motor 103 in the rotational track of the operating lever 117 An operation switch 121 for interrupting the supplied power is provided to protrude from the casing 101. In addition, the release preventing plate 115 on which the operating lever 117 is formed is elastic to press the operating lever 117 to a position to press the air gear 109 toward the small gear 105 and press the operating switch 121. An adjustable spring 119 is provided between the casing 101. In this embodiment, the groove 133 is formed around the release preventing plate 115 on which the operating lever 117 is formed, and the spring 119 fixes its one end to the operating lever 117 and the release preventing plate. The structure in which the groove 133 of 115 is turned and the other end is fixed to the control lever 135 is shown (refer FIG. 10).

The control lever 135 with the spring 119 is exposed to the outside of the casing 101 so that the user can operate by hand, one end of the adjustment lever 135 is a hinge pin formed on the casing 101 ( 137 is rotatably installed and the other end is connected to the spring 119, the casing 101 opposite the connection end of the spring 119, the control lever 135 rotated against the elasticity of the spring 119 in its state The locking projection 139 is formed to maintain the. The operation of the actuating lever 117, the spring 119, and the adjusting lever 135 will be described later.

The above-described operation switch 121 is a switch for controlling a circuit for supplying power to the motor 103, the button is selectively pressed by the fixed terminal 141 and the operating lever 117 fixed to the casing 101. It is composed of a movable terminal 143 of elastic having a 145, when the operating lever 117 presses the button 145, the movable terminal 143 is in contact with the fixed terminal 141, the power supply to the motor 103 When the pressing force of the operation lever 117 is removed from the button 145, the two contacts are separated by the elasticity of the movable terminal 143.

Hereinafter, arrangement configurations of the small gear 105, the rope winding drum 107 including the standby gear 109, the drum shaft 111, the rotating plate 113, the operating lever 117, and the operating switch 121 The operation will be described with reference to FIGS. 10, 11, and 13. First, the operation lever 117 integrally formed on the release preventing plate 115 attached to the rotating plate 113, the release preventing plate 115 between a position closest to and farthest from the center (0) of the rotating plate 113. The drum shaft 111 of the rope winding drum 107 is rotated with respect to the small gear 105 by rotating the operation lever 117 in the direction of the arrow or vice versa by hand. It is possible to move within a distance corresponding to twice the distance between the center 0 and the center 0 'of the drum shaft 111. This is because the drum shaft 111 is formed eccentrically on the rotating plate 113. Therefore, when the operation lever 117 is moved in the direction opposite to the arrow, the distance between the axis (drum axis: 111) of the standby gear 109 and the rotation axis 127 of the small gear 105 becomes farther, and thus, at least a certain point. Turning the operating lever 117 in the opposite direction to the arrow releases the engagement between the small gear 105 and the standby gear 109 so that the rope towing drum 107 can idle, and conversely, the operating lever 117 moves in the direction of the arrow. Since the distance between the standby gear 109 and the small gear 105 becomes closer to each other, when the operating lever 117 is turned in the direction of the arrow more than a certain point, the engagement between the small gear 105 and the standby gear 109 is increased. The small gear (motor) and the rope tow drum 107 are interlocked again.

In this embodiment, when the actuating lever 117 reaches the position where the actuating switch 121 is installed, the small gear 105 and the standby gear 109 are normally engaged, and rotated in the opposite direction to the arrow so as to rotate in Fig. 13C. The engagement of the two gears 105, 109 is configured to reach the position shown in FIG. In the latter position, the standby fish 109 protrudes outward through the slit groove 147 formed on the side of the casing 101.

The tow rope 123 and the mounting hole 125 and the opening and closing time setting means 71 of the table clock part 5 may be applied as it is described in the manual-type sliding door automatic opening and closing device 1 as described above. And explanations are omitted. However, since the motor type automatic opening and closing device 1 'opens and closes the sliding door by the force of the motor 103, it is preferably supplying alternating current to the motor 103, and thus the switch contact of the opening and closing time setting means 71 77 is wired to interrupt the power supplied to the motor 103 (see FIG. 11), and the table clock part 5 is not hinged to the sliding door opening and closing part 3 'and is formed separately. Only point is different.

Also in this embodiment, as in the previous embodiment, it is configured to supply power to the motor 103 at a predetermined time by using a general timer having a sliding door opening / closing time setting means 71 and a switch contact 77 instead of the tabletop system. You can do it.

Hereinafter, an operation of opening and closing the sliding door by the motorized sliding door opening and closing device 1 'will be described with reference to FIGS.

First, the plug 151 of the electric wire 149 for supplying power to the motor 103 is connected to the outlet 153, and the opening and closing time setting needle 73 of the opening and closing time setting means 71 is set on the table clock part 5. By operating the opening and closing time adjustment screw 81 on the back side is set at the time to open the sliding door (85). Next, in the state in which the operating lever 117 is turned in the opposite direction to the arrow (the state in FIG. 13C), the inner door in which the sliding door 123 is opened and closed by appropriately pulling the towing rope 123 in accordance with the size of the sliding door 88. Hook the hook 155 of the towing rope 123 at the proper position of (87) and hang the installation tool 125 on the opposite wall of the inner door 87 or the door holder is installed on the sliding door. Then, the operation lever 117 is turned in the direction of the arrow again so that the terminals 141 and 143 of the operation switch 121 are connected.

As time passes, when the hour hand 75 reaches the position of the opening and closing time setting needle 73 of the opening and closing time setting means 71, the switch contact 77 is connected to supply the power supplied to the motor 103 to connect the motor 103. ) Will begin to rotate. Rotation of the motor 103 is transmitted to the rope winding drum 107 through the small gear 105 and the air gear 109 which are bitten each other, so that the rope winding drum 107 rotates, thereby eventually leading to the towing rope 123. The hanging inner door 87 is opened or closed. When the inner door 87 starts to open, a load is applied to the towing rope 123, and the drum shaft 111 of the rope winding drum 107 is in an eccentric position from the center (0) of the rotating plate 113, so that the rotating plate 113 Is subjected to the force to rotate about the center (0) to the side under load (see Fig. 13A). However, the rotation of the rotating plate 113 is limited by the spring 119, and the center (0) of the rotating plate 113 and the center (0 ') of the drum shaft 111 is shown in Figure 14 (A). Since it is inclined as described above, a much larger load is required to rotate the rotating plate 113, and thus the towing rope 123 is pulled by the rope towing drum 107 without rotating the rotating plate 113.

The opening and closing of the inner door 87 is no longer towed because the stopper 59 installed in the tow rope 123 described in the position of the door or the hand-held device is caught by the guide hole 157 of the casing 101. Towed until disappeared. In this state, since the motor 103 continues to rotate, the load applied to the rope guru drum 107 increases rapidly. As soon as this load exceeds the force of the spring 119, the spring 119 is extended and the rotating plate ( 113 is rotated to the load side in the rotating plate insertion hole 131 of the casing 101 (see Fig. 13 (B)). At this time, the actuating lever 117 moves as well, and the actuating switch 121 is released from the pressurization of the actuating lever 117 so that the contacts of the terminals 141 and 143 are separated and the power supplied to the motor 103 is turned off. Operation stops.

The magnitude of the load required for the rotating plate 113 to rotate changes when the elastic force of the spring 119 or the relative position of the center 0 of the rotating plate 113 and the center 0 'of the drum shaft 111 is properly selected. As such, the device 1 ′ of the present embodiment may be adjusted according to the size of the sliding door used. In addition, as described above, the spring 119 is connected to the adjustment lever 135 rotatably installed on the hinge pin 137 formed on the casing 101, and rotates the adjustment lever 135 to the locking projection 139. By hooking can increase the impact force of the spring 119, one sliding door automatic opening and closing device (1 ') may be used to open and close various sliding doors of different sizes.

On the other hand, assuming that the operation switch 121 is in the on-state even though the operation switch 121 malfunctions and is released from the pressurization of the operation lever 117, the load is continuously applied to the traction rope 123. The rotating plate 113 will be rotated to the position shown in 13 (C), and the engagement between the small gear 105 of the motor 103 and the standby gear 109 of the rope winding drum 107 will be released. Since the motor 103 is idle, the motor is not overloaded and damaged for a long time.

In the case of using the apparatus 1 ', when it is necessary to adjust the length of the towing rope 123 wound on the rope winding drum 107, when the motor 103 is used, it may take a long time because the speed of the motor is low. have. Therefore, in such a case, by turning the operating lever 117 in the opposite direction of the arrow to the position of Fig. 13 (C) by hand, the pulling rope 123 can be pulled out, and the slit groove 147 of the casing 101 can be pulled out. The tow rope 123 protruding by hand may be wound around the rope winding drum 107 by the towing rope 123.

By the series of operations as described above, the sliding door can be opened and closed automatically as desired at a desired time. In addition, it is natural that the stopper 59 and the auxiliary rings 90 and 92 used in the spring 1 may also be used in the device 1 'of the present embodiment using the motor.

In addition, in the case of using the apparatuses 1 and 1 'of the present invention to automatically open a window at the same time as the use of the air conditioner 159 is stopped, a radio signal transmitter that emits radio waves when the air conditioner 159 is stopped. 161 is attached to the air conditioner 159, and a radio receiver 163 capable of receiving radio waves is attached to the apparatuses 1 and 1 'so that the solenoid stopper of the manual-winding switch 1 according to the radio signal is attached. 21 or the switch contact for supplying power to the motor 103 of the motorized switch 1 'may be configured to be turned on. According to this configuration, all the sliding doors on which the apparatus of the present invention is installed can be temporarily opened when the air conditioner is stopped.
