Description

Detachable sliding door automatic switchgear

(Technology field)

The present invention relates to a removable sliding door automatic opening and closing device, and more specifically, to a sliding door installed in the existing sliding doors and automatically sliding in accordance with the operating time entered into the timer (time switch) or the stop time of the air conditioner The present invention relates to a sliding door automatic opening and closing device that can be easily opened or closed.

(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 common 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 device 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.

However, opening and closing the door is not very inconvenient during the daytime activities, but it is quite inconvenient and annoying to get up and go to bed during bedtime. 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, it may be annoying at dawn, a time when a deep sleep is aroused, and may cause a health injury, such as catching a cold, by going to bed continuously without going to close the window.

Also, in the case of a typical tropical night in summer, where the temperature is slightly hot at dawn and the temperature is low at dawn, sleeping on the air conditioner until dawn not only exposes you to the cold wind of the air conditioner for a long time, but also increases the power consumption and is uneconomical. to be. 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 when the temperature drops relatively early, 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.

Therefore, the object of the present invention is to automatically open or close the sliding doors, which are widely used as windows or living room doors, in the hot summer season when the air conditioner is operating or during the sleeping season, when the doors are reserved. It is a sliding door automatic opening and closing device that can maintain temperature comfortably and allow ventilation, and it is to provide a removable sliding door automatic opening and closing device that can be easily installed and detached on an existing door.

Hereinafter, with reference to the accompanying drawings, the removable sliding door automatic opening and closing device according to the present invention will be described in detail. The following embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Hereinafter, the same reference numerals are used for the same components.

1 is a view showing an example of a removable sliding door automatic opening and closing device according to the present invention used.

As shown, the removable sliding door automatic opening and closing device 1 is basically a rope towing device 3, a rope drum rotating device 5, a towing rope 7, and a rope towing device installation rope 9. Consists of a configuration including, is installed in the casing (11).

The rope traction device 3 is a device that provides power to open and close the sliding door, and is composed of a rope drum 13 and a spring 15. The rope drum 13 is a drum rotatably installed on the shaft 17 formed in the casing 11 so that the rope is directly wound or unwound. The rope drum 13 is provided with a gear 19 which is formed integrally with the rope drum on one side thereof and rotates together.

On the opposite side of the gear 19 of the rope drum 13, one end is fixedly wound on the shaft 17 and the other end of the belt steel (helical spring; 15) is fixed to the other end on a spring barrel (barrel) 21. It is. The mainspring barrel 21 is a member for fixing one end of the mainspring 15 and covering the mainspring. In Fig. 1, the shaft 17 is fixed to the casing 11, and the rope drum 13, the gear 19, and the spring barrel 21 rotate integrally with respect to the shaft 17. Is shown. Therefore, when the rope drum 13 rotates together with the mainspring barrel 21, since one end of the mainspring 15 is fixed to the fixed shaft 17 and the other end is fixed to the rotating main barrel 21, The spring 15 is wound or unwound from the side fixed to the spring barrel 21 according to the rotation of the rope drum 13 (rotation of the spring barrel). Unlike FIG. 1, the shaft 17 is rotatably installed in the casing 11, the main barrel 21 is fixed to the casing 11 so as not to rotate, and the rope drum 13 is fixed to the shaft 17. It is also possible to configure to rotate with). In this case, when the rope drum 13 rotates, the shaft 17 is rotated so that the mainspring is wound or unwound from the side fixed to the shaft 17.

The mainspring 15 is wound around the shaft 17 in a direction in which it is wound when the rope is released from the rope drum 13 to store the elastic force and provides a force for the rope to be wound on the rope drum as the wound spring is released.

In the rope drum rotation control device 5 provided adjacent to the gear 19 of the rope drum 13, the spring 15 wound around the shaft 17 according to the time reserved by the user is pulled out by its elasticity. It is a device for controlling the rotation of the rope drum 13 by restricting or permitting, and for example, a bar-shaped stopper 23 which is bitten by the gear 19 of the rope drum so that the rope drum 13 cannot be rotated. And a timer 25 for interrupting the rotation of the rope drum by displacing the stopper 23 to be bitten or loosened by the gear 19.

The timer 25 for moving the stopper 23 is a timer capable of moving a predetermined movable member when the input time comes. In the present invention, the stopper 23 is moved to move the stopper 23 of the rope traction apparatus 3. It performs a function to allow the stopper 23 to be bitten or released on the gear 19. As the timer 25, a mechanical timer having a mainspring, a motor timer, an electronic timer, or the like can be used. It is preferable to use a mechanical timer that does not require a power source. Since the technology related to the timer is a known technology, a description of the specific configuration is omitted. The stopper 23 may be movably supported by the casing 11 to be indirectly moved by an operation bar (not shown) provided in the timer 25 itself, or an operation installed in the timer 25. It is also possible for the bar to act directly as a stopper 23 to bite or loosen the gear 19. In the drawing, reference numeral 27 denotes a timer operation handle.

When the stopper 23 is reliably bitten by the gear 19 and the stopper 23 is bitten by the gear 19, when the gear 19 is rotated in the direction in which the rope is released ( When the rope is pulled by hand), the gear 19 can be rotated, but on the contrary, when the force of the gear 19 is rotated in the direction in which the rope is wound by the elastic force of the spring 15, the stopper 23 can be rotated. In order to prevent it from being rotated), the teeth of the gear 19 are formed with the teeth of a tooth like a latch wheel 45 to be described later, and the stopper 23 has a weak elasticity in a state of being bitten by the gear 19. The gear 19 can be formed to be retractable. For example, when a spring (not shown) is installed on the stopper 19 to receive a weak force joined to the gear 19, when the stopper 23 is bitten by the gear 19, depending on the characteristics of the sawtooth teeth, The stopper 23 is pushed by the gentle inclination of the sawtooth in the direction in which the rope is released, so that the gear 19 can be rotated. It can not be rotated. At this time, it is natural that the force of the timer 25 to retract the stopper 23 from the gear 19 should exceed the elasticity of the spring attached to the stopper.

The rope drum 13 is connected to a tow rope 7 which is wound and unwound on the drum as the drum rotates. The tow rope 7 has one end thereof fixed to the rope drum to be a starting point for the rope to be wound, and the other end of the rope 7 to hang on the hooks 79, 79 ′, 81 attached to the door frame or the door frame 31. ) Is attached and extends outward from the rope drum 13 through the rope guide hole 33 formed in the casing 11. The spring 7 of the rope towing device 3 is wound so that the elastic force is stored in the spring, and the rope 7 is unwound without being wound around the rope drum 13. At this time, when the mainspring 15 is released, the rope drum 13 is rotated so that the rope 7 is wound. When the rope 7 is pulled again, the rope drum 13 rotates in the opposite direction, and the spring 15 is wound to store the elastic force.

A rope traction device mounting rope 9 is provided on the opposite side of the tow rope 7. One end of the installation rope (9) is fixedly connected to the casing (11), and the other end has a hook (35) for hanging on the hooks (79, 79 ', 81) attached to the door frame or door frame.

The length of the two ropes 7, 9 is such that the sum of the lengths corresponds to the maximum length that is typically used as the transverse length of the sliding door. In general, the towed rope 7 is raised and the installation rope 9 Is preferably shorter.

According to the removable sliding door automatic opening and closing device 1 of the present invention configured as described above, between the door frame and the hooks 79, 79 ′, 81 of the door frame to which the hooks 31 and 35 hang on the towed rope 7. Pulled to length, one of the two hooks (31, 35) can be easily hooked to the hooks (79, 79 ') attached to the door frame and the other hangs on the hook (81) attached to the door frame, As a result, the timer 25 releases the stopper 23 bitten by the gear 19 from the gear 19 at a predetermined time, thereby opening and closing the sliding door by the elastic force of the spring 15.

The device of the present invention is to open and close the sliding door by the elastic force stored by winding the spring 15 when the rope 7 is pulled by hand and the rope is released from the rope drum 13. The length of the elastic energy stored in the mainspring 15 varies depending on the length. That is, when the size of the sliding door in which the device is used is small (the length between the hooks of the device is short), the pulled length of the to-be-held rope 7 is relatively short and the elastic force stored in the mainspring 15 is short. This is relatively small. On the contrary, when the size of the sliding door is relatively large, the pulled length of the dog rope 7 is relatively long, and the spring force 15 is relatively large. Therefore, the rope drum (when the rope is wound around the hook 31 of the towed rope 7 or the mounting rope 9 so that an appropriate elastic force suitable for the size of the sliding door can be applied to the sliding door. It is preferable to be able to adjust the length of the rope (7) pulled from 13). For example, as shown in FIG. 1, a spool 37 is formed on the hook 31 to adjust the length of the tow rope 7 wound around the spool 37 to adjust the elastic force of the spring 15. I can regulate it. Although the example in which the spool 37 was formed in the hook 31 of the tow rope 7 is shown in FIG. 1, it is also possible to form the spool in the hook 35 of the installation rope 9. As shown in FIG.

Since the device of the present invention opens and closes the sliding door by using the elastic force of the mainspring 15, according to the essential characteristics of the mainspring, the moment when the door starts to open or the door starts to close by the device of the mainspring 15 It is strongest at the moment (i.e. the moment the spring starts to unwind), and the weaker the moment the door opens and closes as the elastic force decreases as the door opens or closes. Therefore, the present invention distributes such a non-uniform distribution of the elastic force as uniformly as possible to prevent the rapid rotation of the rope drum 13, the rope drum rotational speed adjusting device for adjusting the rotational speed of the rope drum 13 ( 41) can be added.

2 is a view showing an example including a rope speed adjusting device 41 as another example of the removable sliding door automatic opening and closing device 1 according to the present invention, Figure 3 is a configuration of the rope drum speed adjusting device 41 Figure showing.

The rope drum rotation speed adjusting device 41 is installed between the gear 19 and the stopper 23 of the rope drum 13, as shown in FIGS. 2 and 3, and the stopper 23 is geared. Rope drum speed consisting of a pinion (43), a latch wheel (45), a counterweight (49) and a braking weight (51) without being directly bitten or loosened by (19). It consists of a configuration including an adjustment weight 47, and the brake drum (53). In this case, unlike the first embodiment described above, the teeth of the gear 19 are not formed as sawtooth teeth but are formed as general teeth.

The pinion 43 is a relay gear for rotating the latch wheel 45 and the rope drum speed adjusting weight 47 by receiving the rotation of the gear 19. The pinion 43 is provided with a latch wheel 45 formed with a plurality of cog teeth, which rotate together with the pinion 43 about the same axis, and which the stopper 23 bites. Therefore, when the pinion 43 rotates by the gear 19, the latch wheel 45 also rotates integrally. A plurality of jagged teeth formed on the latch wheel 45 corresponds to the teeth of the gear 19 in the structure in which the stopper 23 directly bites the gear 19 described above, so that the latch wheel is bitten and released. The rotation of 45 is interrupted.

On the side of the latch wheel 45 opposite to the pinion 43, a rope drum speed adjusting weight 47 is fixedly attached to the latch wheel 45 and rotates with the latch wheel about the same axis as the axis of the latch wheel. have. Rope drum speed adjustment weight 47, the balance weight 49 and the braking weight (51). As shown in FIG. 3, the counterweight 49 is a weight that is fixedly installed on the latch wheel 45 to impart inertia to the rotating members 13, 19, 43, 45, and the like of the device. For example, the center of gravity may be formed in a butterfly shape located at the center of the rotation axis of the latch wheel (45). Forming the counterweight 49 in the shape of a butterfly is to provide an installation space for the braking weight 51. For example, as illustrated in FIG. 3, the braking weight 51 is symmetrically installed on two recesses of the butterfly-shaped balancing weight 49 and has a scoop shape. The portion corresponding to the handle of the scoop is fixed to the latch wheel 45 so as to be pivotable by the hinge pin 55 and is installed to be pressed toward the center of the rotation axis of the latch wheel 45 by the spring (57). Therefore, when the latch wheel 45 rotates and the centrifugal force greater than the elasticity of the spring 57 acts on the brake weight 51, the brake weight 51 opens outward.

Around the brake weight 51, a brake drum 53 provided in the casing 11 of the apparatus is installed so that the brake weight 51 in contact with the brake weight 51 receives frictional resistance to brake its rotation.

According to the rope drum rotational speed adjusting device 41 as described above, the stopper 23 is separated from the latch wheel 45 in the state in which the mainspring 15 is wound and the rope drum 13 is moved by the elasticity of the mainspring 15. When the pinion 43, the latch wheel 45, and the rope drum speed adjusting weight 47 start to rotate, the inertia of the counterweight 49 prevents sudden rotation of the rotating members, and secondarily. When the speed of the rotating members reaches a predetermined speed or more, the braking weight 51 overcomes the force of the spring 57 by centrifugal force and is rubbed by the brake drum 53 to reduce the speed of the rotating members, so that the rope drum 13 ) Is prevented from rotating rapidly. As the rotational speed of the latch wheel 45 increases, the centrifugal force (braking force) of the braking weight 51 increases, so that the rope drum 13 does not rotate over a predetermined speed. In addition, when the mainspring is almost completely loosened and does not provide sufficient elastic force, the brake weight 51 is separated from the brake drum 53 by the spring 57 so that rotation is not braked, and the inertia of the counterweight 49 is caused by the rope drum ( 13) is maintained so that the rotation speed is gradually reduced. Therefore, opening and closing of the sliding door can be performed more smoothly by the rope drum rotation speed adjusting device 41.

The pinion 43 rotates when the gear 19 rotates in the direction in which the spring 15 is released, and the pinion 43 meshes with the gear 19, and the gear 19 rotates in the spring 15. When rotating in this winding direction, the pinion 43 may not be completely engaged by the gear 19 so that the pinion 43 may not be rotated. 4 shows an example of the pinion configured as described above. That is, as shown in Figs. 2 and 4, the pinion 43 is rotatably supported by a rod 59 installed horizontally so as to be pivotable, and a spring 61 for pressing the rod 59 downward is applied. A support 63 connected between the rod 59 and the casing 11 and supporting the rod 59 at a position where the pinion 43 is correctly snapped by the gear 19 has a lower portion of the rod 61. The structure installed in the above can be added to the pinion 43. Here, reference numeral 65 denotes a hinge axis that pivotally supports the rod.

Accordingly, when the gear 19 rotates in the clockwise direction (rotational direction when the rope is wound around the rope drum to open and close the door) in Fig. 4, the gear drum 19 and the pinion 43 mesh with the rope drum. Rotating members of the rotation control device 41 rotates to perform a rotation speed adjusting function of the rope drum. On the other hand, when the gear 19 rotates in the counterclockwise direction (the rotation direction when the towing rope is pulled from the rope drum by hand pulling), the pinion is lifted so that the gear 19 and the pinion 43 do not bite. Thus, when pulling the tow rope 7 by hand (no need to adjust the rotational speed of the rope drum), the rotational members of the rope drum rotation control device 41 do not rotate and therefore the rope 7 with less force. Can pull. Further, even when the stopper 23 is pulled by the latch wheel 45 by the mistake of operating the timer 25, the rope is pulled without damaging the apparatus.

When the pinion 43 pivots about the hinge shaft 65 by the rod 59, the latch wheel 45 and the counterweight 49 of the rope drum rotational speed adjusting device 41 fixedly attached to the pinion. , And the braking weight 51 and the like also turn with the pinion 43, so that the brake drum 53 surrounding the braking weight 51 should also be turned with the pinion 43. Thus, as shown in Fig. 2, the brake drum 53 is also fixed to the hinge shaft 65 and pivoted with the rotation of the rod 59. Here, reference numeral 67 denotes a pedestal having a shaft hole for rotatably supporting the hinge shaft 65 and fixed to the casing 11.

The rope drum rotation control device 5, as shown in Figs. 1 and 2, a solenoid (29) for converting electrical signals into mechanical linear motion and a separate displacement by the solenoid (29) A stopper 23 'can be added. For example, when the current flows, the movable iron piece is moved between the coils so that the stopper 23 'is additionally provided with a solenoid 29 which acts to disengage from the gear 19 or the latch wheel 45, and the solenoid ( The power supplied to 29 is supplied from the outlet 85 configured in the circuit of the air conditioner so that the power is cut off when the air conditioner 83 is operating and the power is supplied when the air conditioner 83 is stopped. It can be used to open the door at the same time as it stops. That is, the stopper 23 ', which is moved by the solenoid 29, is installed so that one end thereof protrudes slightly out of the casing 11, and the stopper 23' is latched by the spring 19 (not shown). It is to be pressed lightly toward the departure from the wheel (45). In addition, the solenoid 29 is configured such that when the power is supplied, the stopper 23 'moves away from the gear 19 or the latch wheel 45. When power is not supplied to the solenoid 29, the stopper is not bitten by the gear 19 or the latch wheel 45 by the spring of the stopper 23 '. The rotating members of the rotating springs 15 are wound. Pull the rope 7 as necessary, and then loosen the rope 7 slightly while pressing the protruding portion out of the casing 11 of the stopper 23 ', so that the stopper 23' The gear 19 and the latch wheel 45 cannot rotate until the current flows in the solenoid 29 due to the teeth of the latch wheel 45.

When the solenoid 29 is not used, since the stopper 23 'is separated from the gear 19 or the latch wheel 45 by the spring, there is no problem in opening and closing the door by the timer and the stopper 23. There is no In addition, when opening the door by the solenoid 29 and the stopper 23 ', by setting the timer to zero, the stopper 23 is released from the gear 19 or the latch wheel 45, so that the solenoid 29 ) And opening of the door by the stopper 23 'are not obstructed.

In FIG. 1 and FIG. 2, both the timer 25 and the solenoid 29 are installed so that only the timer 25 is normally used, and when the air conditioner is stopped and the door is opened at the same time in the summer using the air conditioner 83. An example is shown in which zero (0) is input to the timer 25 and the stopper 23 'can be opened by the operation of the solenoid 29 to open the door. However, if only the timer 25 is installed and the timer is adjusted to the time when the air conditioner is stopped, the door can be opened near the time when the air conditioner is stopped.

1 and 2, the solenoid 29 and the stopper 23 ′ are shown in the drawing so as to protrude from the side of the casing for the sake of clarity in the drawings. However, the solenoid 29 is the gear. (19) or latch wheel 45, the stopper (23 ') is a position that can be snapped and released inside the casing (11), for example, the gear 19 or the latch wheel ( 45) can be installed on top.

Hereinafter, an operation of opening and closing the sliding window by the removable sliding door automatic opening and closing device according to the present invention will be described with reference to FIGS. 5 and 6.

First, the process of closing the sliding window will be described with reference to FIG. 5. Prior to installing the device 1 of the present invention on the sliding window 69, the lower ends of the vertical window frames 71 and 71 'on both sides of the window or both ends of the horizontal window frame 73 and the lower window of the inner window 75. In the center of the mold 77, the hooks 79, 79 ', 81 for hanging the hooks 31, 35 of the apparatus are provided. Then, the hook 35 of the installation rope 9 is hooked to the hook 79 'on the side where the window is opened, and the hook 7 is pulled to the hook 81 of the window frame 77 by pulling the towing rope 7. (You can change the hanging positions of the two hooks). At this time, the elastic force of the spring 15 felt by the hand is judged to wind the rope 7 on the spool 37 of the hook 31 of the to-be-held rope 7 so that the appropriate elastic force is stored in the spring. Next, the time to close the door is input by the handle 27 of the timer 25.

In this manner, when the apparatus 1 is installed and sleeps in the state where the window 69 is opened, the timer 25 moves the stopper 23 at the scheduled time so that the stopper 23 is released from the latch wheel 45. Since the spring 15 is released, the rope 7 is wound around the rope drum 13 so that the inner window 75 moves in the direction of the arrow to close. When the door is closed, the rope drum speed regulating device 41 is operated to close the door gently.

On the other hand, when opening the window, the hook 35 of the installation rope 9 is hooked on the hook 79 of the window frame 71, and the hook 31 of the towed rope 7 is hooked by the hook of the inner window frame 77 ( 81) Same as closing door except hanging.

In addition, as shown in Figure 6, after installing the device of the present invention in the state that can open the door to the sliding door, input the zero (0) to the timer 25 and the plug 87 of the solenoid 29 And the outlet 85 of the air conditioner 83 are connected to the electric wire 89, the solenoid 29 at the moment when the air conditioner stops after the time input to the timer (not shown) of the air conditioner 83 itself has elapsed. The solenoid 29 causes the stopper 23 'to be disengaged from the gear 19 or the latch wheel 45, the rope drum 13 is rotated and the rope 7 is wound up. The window may be opened when the air conditioner 83 is stopped.

According to the removable sliding door automatic opening and closing device according to the present invention described above, by simply attaching a hook to a conventional sliding window or living room door, the device is simply installed and reserved in advance while asleep. Sliding doors can be opened or closed automatically with a simple operation at a time, which keeps the room's temperature comfortable and ventilates, thus preventing harm to health due to temperature changes. In addition, the device is temporarily installed in the window only during the late spring or early autumn season or during summertime, and when not in use, the device can be removed and stored separately so that the interior of the room is not damaged at all.

In addition, since the device of the present invention is used to open and close the sliding door slowly while asleep, not only can the component parts be compactly manufactured, but also the length of the ropes can be adjusted for doors of different sizes. Because it can be used, it can be widely applied regardless of the size of the door.

In addition, by using only a mechanical timer, the sliding door can be opened and closed at a predetermined time without supplying power.
