If necessary, the power transmission unit may further include a sensor unit (not shown).

The sensor unit detects a person entering and exits a sliding window and controls the operation of the motor, and includes one or more human body detecting sensors. At this time, the human body sensor and the motor is connected by wire or wirelessly.

The human body sensor is installed on the outer surface, the inner surface of the door or both of them to detect the entrance and exit of the person, any sensor used for this purpose may be used, but preferably the distance control of the human body detection It is recommended to use a passive infrared sensor (PIR) sensor. That is, the human body detecting sensor provided on the inner side of the door is adjusted so that the human body detecting distance of the sensor is shorter than the human body detecting sensor provided on the outer side of the door, so that the automatic switching device is unnecessary by the person moving the room. Prevent it from working.

In addition, a sensor that detects the movement of the handle of the door separately from the PIR sensor may be attached to one side of the door so that a person using the door may press the handle to stop the motor and manually move the door. This is to prevent the automatic opening and closing device from being broken by providing an external force to the sliding window while automatically controlling the sliding window through the automatic opening and closing device.

Opening and closing device of the sliding window according to an embodiment of the present invention includes a wire (W).

The wire (W) is to connect the first transfer plate 110 and the second transfer plate 120 so that the second window 20 is interlocked with the movement of the first window 10 to open and close the sliding window. .

More specifically, the wire (W) is fixed to the first transfer plate 110, is spread over both ends of the second transfer plate 120 so as to be free to move, according to the movement of the first transfer plate 110, the second Any one of both ends of the transfer plate 120 is pulled to operate the second transfer plate 120 to interlock with the first transfer plate 110. That is, as the pulling force is generated on the wire W by the movement of the first transfer plate 110, the wire W is changed in direction and spans both ends of the second transfer plate 120. The second transfer plate is interlocked by pulling the wires on either end of the two transfer plates.

In order for the movement direction of the first transfer plate 110 and the interlocked movement direction of the second transfer plate 120 to be the same, pulling of the wire W generated by the front and rear sliding movement of the first transfer plate 110 is performed. The force should act as a pulling force in the same direction of travel to the second transfer plate (120). To this end, the wire W extends from the front end 111 of the first transfer plate 110 to be wound around the rear end 122 of the second transfer plate 120, and then passes through the passage groove 126a for the second transfer. After winding to the front end 121 of the plate 120 is fixed to the rear end 112 of the first transfer plate (110).

Meanwhile, as shown in FIG. 3, the wire W traveling forward from the front end 111 of the first transfer plate is switched by the first pulley P1 to change the direction of movement of the first guide rail 101. Proceeds to the third pulley (P3) across the front and rear, the direction is further changed by the third pulley (P3) and fourth pulley (P4) proceeds to the rear end 121 of the second transfer plate. Thereafter, the traveling direction is changed by 180 degrees after being wound around the transfer pulley 150 of the rear end portion 122 of the second transfer plate, and then proceeds to the rear of the second transfer plate 120 again. In addition, the wire W is wound on the rear pulley Pr, and the traveling direction is changed again to reach the front pulley Pf. The wire W is wound on the front pulley Pf, and the traveling direction is changed, this time the front end of the second transfer plate. It is wound around the transfer pulley 150 of 121 and the traveling direction is changed again by 180 degrees and then proceeds to the front of the second transfer plate 120. After that, the wire W passes through the second pulley P2, the first pulley P1, and the third pulley P3, and the direction of travel is shifted to the rear end 112 of the first transfer plate to move the first. It is fixed to the plate 110.

Thus, when the first transfer plate 110 is moved to the rear end portion of the first guide rail 101, the pulling force of the wire (W) which is advanced at the front end of the first transfer plate 110 is the second transfer plate ( 120) pull the guide rail backwards.

At this time, the wire W in which the traveling direction is changed in the rear pulley Pr is moved to the front pulley Pf through the passage groove 162a. As a result, a portion of the wire W may not pass through the inside of the second guide rail 102, thereby reducing the resistance element during the sliding movement of the second transfer plate 120. That is, the wires W extending across the front pulley Pf and the rear pulley Pr do not pass through the inside of the second guide rail 102 to act as a frictional resistance during the sliding movement of the second transfer plate 120. The wire W is pulled out of the second guide rail 102.

Meanwhile, when the first transfer plate 110 moves forward or backward, the wire W4 in the section from the rear pulley Pr to the front pulley Pf is a wire generated by the movement of the first transfer plate 110. It becomes a section in which the pulling force of weakly reflected, so that the first transfer plate 110 and the second transfer plate 120 is 2: 1 ratio. That is, the wires W4 from the rear pulleys Pr to the front pulleys Pf are each farthest of the entire wires fixed at the first transfer plate 110, and the wires W4 pass through the plurality of pulleys in turn. The pulling force gradually decreases due to the rotational resistance and the direction change of the wire many times. In addition, since the wire W4 wound on the front pulley Pf and the rear pulley Pr is wound on half of the outer circumferential surface of each pulley and the traveling direction changes rapidly by 180 degrees, the front pulley Pf and the rear pulley Pr The resistance of the wire W4 passing through is greater than the resistance of the wires W1 to W3, W5 to W7 passing through the first to fourth pulleys P1, P2, P3, and P4. Therefore, the first transfer plate 110 and the second transfer plate 120 are interlocked at the same time in a ratio of 2: 1.

As such, the wires W3, W4, W4, and W5 spanning both ends of the second transfer plate 120 are freely rotatable at the front and rear ends of the second transfer plate 120 and are coupled to the free ends. One of the wires W4 parallel to the front and rear ends of the second transfer plate 120 is not moved over the front pulley Pf or the rear pulley Pr, and the other one W3 or W5 Since the second conveying plate 120 is pulled by a wire that spans the second pulley P2 or the fourth pulley P4, the second transfer plate 120 passes through the second pulley P2 or the fourth pulley P4 (W3 or W5). It is moved forward by 1/2 of the length that is pulled into it.

At this time, the rear pulley (Pr) and the front pulley (Pf) is the first pulley to the fourth pulley (P1, P2, P3, P4) so that the forward movement of the 1/2 length of the second transfer plate is more reliably made It is preferable that the rotational resistance is formed larger than that. That is, the wire W4 spanning the rear pulley Pr and the front pulley Pf is not moved, thereby being pulled by the wire W3 or W5 passing through the second pulley P2 or the fourth pulley P4. The second conveying plate 120 is to be conveyed by an exact length of half the length. At this time, the length of the wire (W3 or W5) is pulled across the second pulley (P2) or fourth pulley (P4) is due to the sliding movement of the first transfer plate 110, and eventually the first transfer plate 110 ) And the moving distance of the second transfer plate 120 is 2: 1.

In order to make the rotational resistance of the rear pulley Pr and the front pulley Pf relatively larger than the rotational resistance of the first to fourth pulleys P1, P2, P3 and P4, the first to fourth pulleys The bearings constituting (P1, P2, P3, P4) can be used with lower rotational resistance than the bearings constituting the front pulley Pf and the rear pulley Pr.

Opening and closing device of the sliding window according to an embodiment of the present invention may further include a rotating belt.

Referring to FIG. 8, the rotating belt 230 ′ is in contact with the outer circumferential surface of the first pulley P1 and the third pulley P3 or between the second pulley P2 and the fourth pulley P4 to transmit power. By transmitting the rotational force of the pulley rotated by (210, 220, 230, 240) to another pulley, serves to assist the wire (W) to rotate smoothly. Specifically, the rotary belt 230 ′ contacts the outer circumferential surface of the bottom bush 164 on which the auxiliary tool 166 having a thread or screw groove is formed, and moves as the bottom bush 164 rotates, thereby using a timing belt. It is preferable.

As a specific aspect, the rotary belt 230 'is provided with one end connected to the front end 111 of the first transfer plate 110 and proceeds to the first pulley P1, and the traveling direction by the first pulley P1. The change is made and proceeds to the third pulley P3 across the front and rear of the first guide rail 101, and the traveling direction is changed again by the third pulley P3, so that the rear end portion of the first transfer plate 110 Proceeds to 112, the other end is connected to the rear end 112 is installed. More specifically, both ends of the rotating belt is connected to the tension control unit 140 formed on the first transfer plate (110).

Accordingly, when the power transmission units 210, 220, 230, and 240 rotate the first poly P1 and the second poly P2, they are freely moved at both ends of the first poly P1 and the third poly P3. The third pulley P3 is rotated at the same speed by the rotation belt 230 ′ which is possibly wound.

Referring to Figure 9, the automatic opening and closing device of the sliding window according to an embodiment of the present invention may further include a stopper block 180.

The stopper block 180 is fixed to both ends of a section in which the first transfer plate 110 and the second transfer plate 120 are moved from the upper portion of the first guide rail 101 and the second guide rail 102. As, it serves to define the movable section of the first transfer plate 110 and the second transfer plate 120.

That is, even when the user operates the window with excessive force or when the weight of the window is large, the window does not leave a certain section, thereby preventing the failure of the interlocking device.

As shown in FIG. 12, one side of the door frame in which the sliding window is installed may be provided with a pocket 40 recessed in a wall to accommodate each window. Thus, when the sliding window is closed, the door frame of the rear end of the first window 10 and the door frame of the front end of the second window 20 overlap (Fig. 13 (c)), and the first window 10 when the sliding window is opened. And in the state where the second window 20 overlaps with each other, it is completely accommodated in the pocket part to ensure the maximum passage space (FIG. 13A).

13A to 13C are views schematically showing a process of opening a sliding window by an automatic opening and closing device of a sliding window according to an embodiment of the present invention.

It is assumed that the first transfer plate 110 is moved forward by 2 m in the sliding window. At this time, the wire (W1) fixed to the rear end of the first transfer plate 110 is pulled by a length of 2m, thereby extending over the third pulley (P3), the first pulley (P1), the second pulley (P2) in order. The wire W2 of the losing section is also pulled by 2 m in length. At this time, since the wire W4 caught on the front pulley Pf is not moved, the wire W3 spanning the second pulley P2 drawn to a length of 2 m is free at the front end of the second transfer plate 120. It is wound in a stage to move the second transfer plate 120 forward by 1m length.

In another aspect, the wire W7 fixed to the front end portion of the first transfer plate 110 is moved forward by 2m length by the first transfer plate 110 moved forward by 2m length, The wire W6 in the section passing through the first pulley P1, the third pulley P3, and the fourth pulley P4 is also moved by 2 m in length. Since the wire W spanned from the rear pulley Pr to the front pulley Pf is not moved, the wire W5 wound around the rear end of the second transfer plate 120 through the fourth pulley P4. By the 2m length provided by, the second transfer plate 120, the wire is suspended from the rear end to the free end is advanced by 1m length. That is, the 2m long wire W6 provided with the first conveying plate 110 forwarded is provided with a wire W5 and a section extending from the fourth pulley P4 to the rear end of the second conveying plate 120. It is required to increase the length by 1m in the wire (W4) of the section from the rear end of the two transfer plate 120 to the rear pulley (Pr). As a result, when the 2m length forward movement of the first transfer plate 110, the second transfer plate 120 is interlocked to move forward 1m length, this movement ratio is kept constant over the interlocking section. That is, 2: 1 interlocking of the first transfer plate 110 and the second transfer plate 120 is made by a wire that is freely movable at the front and rear ends of the second transfer plate 120.

On the other hand, as the second transfer plate 120 is moved forward, the locking bead 190 provided in the front portion approaches. After the locking beads 190 are in contact with the wire hole of the transfer block 130 coupled to the front end of the second transfer plate 120, the first transfer plate 110 is moved to the front movement of the first transfer plate 110. ) And the second transfer plate (110, 120) is the same ratio of movement distance ratio 1: 1 (see Figure 13b).

As such, when the locking ball 190 is caught by the transfer block 130 of the front end of the second transfer plate 120, the first window 10 fixed to the first transfer plate 110 is shown in FIG. 13B. The door frame and the door frame in front of the second window 20 that is fixed to the second transfer plate 120 is a point of overlap. In other words, the sliding window is interlocked with the 2: 1 and the sliding movement is moved to the front and rear door frame of the first door and the second door door hook 190 is installed on the wire by the user so as to be caught on the transfer block 130 do.

In order to explain the 1: 1 dynamic interlocking operation relationship, the first transfer plate 110 is moved forward in a state in which the engaging beads 190 are in contact with the transfer block 130 provided at the front end of the second transfer plate 120. Assume a case of moving by 1m in length.

The wire W1 coupled to the rear end of the first transfer plate 110 is pulled by a length of 1 m, and the pull of the wire 1 of length 1 m is the third pulley P3, the first pulley P1, and the second. It is transmitted to the second transfer plate 120 via the pulley (P2). At this time, since the latching ball 190 is caught by the transfer block 130, the front end of the second transfer plate 120 is no longer a free end, and the second transfer plate 120 is a fixed end to which the wire is fixed. The wire W3 is moved forward by the length of 1m in which it is pulled. In addition, the wire W4 in the section from the rear pulley (Pr) to the front pulley (Pf), the front end of the second transfer plate 120 becomes a fixed end, so the pulling force by the wire caught on the front pulley (Pf) and the rear As the friction force of the pulley (Pr) is won, it is rotated and forcedly moved by 1 m in length as the second transfer plate 120 moves forward. That is, the 1: 1 moving ratio linkage of the first transfer plate 110 and the second transfer plate 120 is a front pulley as the locking ball 190 is caught on the transfer block 130 of the second transfer plate 120. Pf and the rear pulley Pr are forcibly rotated.

Such 1: 1 dynamic interlocking is performed while moving forward by a length corresponding to the door frames of the first door and the second door, until the sliding windows are completely closed as shown in FIG. 13C.

Meanwhile, as shown in FIGS. 14A to 14C, the opening of the window is first opened with the first transfer plate 110 and the second transfer plate 120 interlocked at a 2: 1 ratio, and the first window 10 is opened. When the second window 20 overlaps each other, the locking beads 190 are applied to the transfer block 130 at the rear end of the second transfer plate 120, and then the first and second transfer plates 110 and 120 have a 1: 1 ratio. In conjunction with the first window 10 and the second window 20 is to be completely received in the pocket portion.
