Description

  The present invention relates to an electric folding door device that opens and closes an opening by driving a folding door having a suspension door and a door door that are foldably connected.

  2. Description of the Related Art Conventionally, an electric folding door device that opens and closes an opening by driving a folding door having a suspension door and a door door is known. The electric folding door device is used for various folding doors such as a folding door for a terrace window of a house.

  For example, in Patent Document 1, the suspension door is connected to a drive motor via a rotating shaft and a link mechanism. The door-end door is connected to the suspension door by a hinge so as to be bent. The door-end door has a guide roller that travels along a guide rail disposed over the opening. When the drive motor is actuated, the suspension shaft swings by the rotation of the rotating shaft via the link mechanism, and the door door follows the swing and moves while being guided by the guide rail. Thereby, a folding door is folded and an opening part can be made into an open state.

JP-A-9-144425

  By the way, in recent years, folding doors for terrace windows tend to have a wide opening width. And since airtightness is calculated | required, the airtight packing is mounted | worn with the opening frame, and the airtight packing is also mounted | worn with the connection part of a suspension door and a door-end door. For this reason, the resistance when opening and closing the folding door tends to increase. Therefore, in the conventional method in which the rotating shaft is rotated by one motor as in Patent Document 1, it is difficult to fold the suspension door and the door-end door unless a large motor that generates a large driving force is used. Yes.

  An object of the present invention is to provide an electric folding door device that can reliably open and close a folding door having a large opening and closing resistance without using a large motor.

  The electric folding door device of the present invention is for driving a folding door having a suspension door and a door door that are connected so as to be foldable to open and close the opening. The electric folding door device includes a first opening / closing device and a second opening / closing device. The first opening / closing device increases an arm for swinging the suspension door, a first motor for generating a force for rotating the arm around its axis, and a force generated by the first motor. With a booster. The second opening / closing device includes a second motor that generates a force that moves the door-end portion of the door-end door in the width direction of the opening.

  In a folding door provided with an airtight packing, the resistance when moving in the opening direction and the resistance when moving in the closing direction are large. Therefore, the electric folding door device according to the present invention has a first function for outputting a force for swinging the suspension door and an operation in the opening direction in order to operate the folding door in a direction to open / close the folding door against a large resistance. The second function of outputting a force for operating the folding door at a predetermined moving speed after being started is realized by using separate motors. The first function is mainly realized by the first opening / closing device, and the second function is mainly realized by the second opening / closing device.

  Specifically, the first opening / closing device is configured such that a force booster increases the force generated by the first motor, and the arm rotates about the axis by the increased force. Therefore, even when the folding door is provided with an airtight packing, the suspension door can be swung by the arm whose rotational force is increased, so that the folding door is opened from the closed state. The operation can be started.

  When the folding door starts to move from the closed state to the state where the suspension door and the door-end door are slightly bent, the second motor moves the door-end portion of the door-end door to the opening portion. By generating a force that moves linearly at a predetermined moving speed along the width direction, the door tip portion moves in a direction approaching the suspension door. By dividing the force required for opening and closing in this way into the first function and the second function, the operation until the folding door reaches the fully open state can be made smooth. The predetermined moving speed is a speed at which the first motor and the second motor can be optimally synchronized for opening and closing.

  As described above, in the present invention, since two motors are used for each function and the output of the first motor is increased by the booster, each motor can be downsized while reliably opening and closing the folding door. it can. As a result, the entire electric folding door apparatus can be made compact. Moreover, in this invention, the freedom degree of the arrangement | positioning that the 1st switchgear and 2nd switchgear which were provided separately can be arrange | positioned in the position suitable for exhibiting each function is also provided. Furthermore, in the first opening / closing device, since the arm is used as a member for swinging the suspension door, the folding door can be swung with a simple configuration in which the arm is rotated. Therefore, for example, by applying the electric folding door device of the present invention to a manual folding door, the manual folding door can be easily electrified.

  In the electric folding door apparatus, it is preferable that the first motor is disposed closer to the folding door than the second motor in the thickness direction of the folding door in the closed state.

  In this configuration, since the first motor is arranged closer to the folding door than the second motor in the thickness direction of the folding door, the second motor is arranged closer to the folding door than the first motor. Compared with the case where it is, the arm which swings a suspension door can be shortened. Thereby, since the torque for swinging the suspension door can be reduced, it is possible to suppress an increase in output required for the first motor. As a result, the first opening / closing device can be made compact.

  In the electric folding door device, the second opening / closing device includes a connecting plate extending in the thickness direction so as to transmit the driving force of the second motor to the door end portion, and the connecting plate in the width direction. And a guide plate rail for guiding.

  In this configuration, the connecting plate that transmits the driving force of the second motor to the door-end portion of the door-end door can be smoothly guided in the width direction. Specifically, it is as follows.

  As described above, when the first motor is arranged closer to the folding door than the second motor in the thickness direction, the first opening / closing device having the first motor takes up the space on the folding door side. Occupies to some extent. In this case, the second opening / closing device having the second motor is provided at a position shifted in the thickness direction as a whole with respect to the door-end door. Therefore, the connecting plate that transmits the driving force of the second motor to the door end portion is provided so as to extend in the thickness direction. When such a connecting plate moves in the width direction by the driving force of the second motor, the door end portion also moves in the width direction in conjunction with the connecting plate. Here, since the second opening / closing device is located at a position displaced in the thickness direction as a whole with respect to the door-end door, the driving force of the second motor is the door-end in the connecting plate extending in the thickness direction. It tends to be biased to one side without acting equally on the partial side and the opposite side. As a result, when the connecting plate moves in the width direction, it may not be able to maintain a suitable basic posture and may be inclined with respect to the basic posture, making it difficult to move smoothly.

  Therefore, in this configuration, a connecting plate rail for guiding the connecting plate in the width direction is provided. Thereby, even if it is a case where the force which acts on a door-end part side and its opposite side is not equal in a connecting plate as mentioned above, a connecting plate can be moved smoothly in the said width direction. Thus, since the inclination at the time of a movement of a connection board can be suppressed with a simple structure, it can suppress that the whole electric folding door apparatus enlarges, and can achieve compactization.

  In the electric folding door apparatus, it is preferable that the arm and the connecting plate are arranged so as to overlap each other on a projection surface projected in the horizontal direction.

  In this configuration, since the arm and the connecting plate are arranged so as to overlap in a side view, the entire electric folding door apparatus can be made compact in the height direction.

  In the electric folding door device, the connecting plate includes a portion extending in the thickness direction from the door tip portion toward the connecting plate rail, and the suspension door in the width direction along the connecting plate rail. And a portion extending toward the side.

  In this configuration, since the connecting plate has the L-shaped portion as described above, the arm and the connecting plate are arranged so as to overlap in a side view for compactness in the height direction. However, it can suppress that a connection plate interferes with an arm.

  In the electric folding door device, in the first opening / closing device, the first motor and the booster are configured as separate bodies, and the first motor and the booster are arranged in the width direction. Is preferred.

  In this configuration, since the first motor and the booster are arranged in the width direction, it is possible to arrange the first motor and the booster so that at least a part of them overlaps when viewed in the width direction. (The installation position of the first motor and the booster can be adjusted in the thickness direction), and as a result, it can be made compact in the thickness direction.

  In the electric folding door apparatus, it is preferable that the first motor, the booster, and the second motor are arranged in the width direction.

  In this configuration, since the first motor, the booster, and the second motor are arranged in the width direction, the electric folding door device can be made compact in the thickness direction.

  The electric folding door device preferably includes an attachment base to which the first motor, the second motor, and the booster are attached.

  In this configuration, the first motor and the booster provided separately from each other and the second motor can be positioned on the mounting base and arranged compactly, and the workability can be improved.

  In the electric folding door apparatus, it is preferable that the second motor and the booster are arranged so as to overlap on a projection surface projected in the width direction.

  In this configuration, the second motor and the booster are arranged so as to overlap each other on the projection surface obtained by projecting the second motor and the booster in the width direction. That is, when the second motor and the booster are viewed in the width direction, they are arranged so that at least a part of them overlaps (the installation positions of the second motor and the booster are matched in the thickness direction). Therefore, the whole electric folding door apparatus can be made compact in the thickness direction.

  The electric folding door device includes an arm rail attached to the suspension door, the arm is rod-shaped, and the arm rail guides a tip portion of the arm when the arm rotates. It is preferable to be configured to do so.

  In this configuration, the suspension door can be swung by providing a rod-shaped arm and an arm rail that guides the tip of the arm without using a link or the like. It can be made compact.

  According to the present invention, a folding door having a large opening / closing resistance can be reliably opened and closed without using a large motor.

As shown in FIG. 4, the first opening / closing device 10 includes an arm 13 that swings the suspension door 41 around its axis A1, and a first motor that generates a force that rotates the arm 13 around its axis A4. 11 and a booster 12 that increases the force generated by the first motor 11. In the present embodiment, the first motor 11 and the booster 12 are configured as separate bodies, but are not limited thereto, and may be configured as an integral unit. As the booster 12, for example, the speed reducer 12 having a planetary gear mechanism or the speed reducer 12 having a gear mechanism in combination with a spur gear can be used, but the invention is not limited thereto.

  As shown in FIG. 4, a booster 12 is connected to the output shaft of the first motor 11. As shown in FIGS. 4, 6, and 9, an arm is connected to the output shaft of the booster 12. 13 base end portions 131 are connected. The rotational force of the first motor 11 is input to the booster 12. The booster 12 provided between the first motor 11 and the arm 13 can increase the rotational force of the first motor 11 and transmit it to the arm 13 as a larger rotational force.

  In the present embodiment, since the speed reducer 12 is used as the power booster 12, the power booster 12 decelerates the rotation speed of the first motor 11 at a predetermined reduction ratio and transmits the increased torque to the arm 13. . Thus, the increased torque causes the arm 13 to rotate around its axis A4.

  As shown in FIGS. 4, 6, and 9, in this embodiment, the arm 13 has a rod shape and is arranged in a posture parallel to the horizontal direction. A roller 15 is provided at the tip of the arm 13. On the inner surface of the suspension door 41 on the arm 13 side, an arm rail 14 is attached at a position substantially the same height as the arm 13.

The belt 223 is looped between the pulleys 221 and 222, and the connecting portion 224 is connected to the belt 223. The connecting part 224 is coupled to the connecting plate 23. The belt 223 is provided to convert the rotational power of the second motor 21 into linear movement of the connecting portion 224. The connecting portion 224 moves linearly in the width direction W by driving the second motor 21. That is, the connecting portion 224 moves in the width direction W in conjunction with the driving of the belt 223.

  In addition, the transmission part 22 should just be what can convert the rotational power of the 2nd motor 21 into the linear motion of the width direction W, and is not limited to the above structures. As the transmission part 22, a transmission means such as a ball screw can be employed. When the transmission part 22 is a ball screw, the connection part 224 is formed of a nut member and moves linearly in the width direction W by rotating relative to the screw shaft. That is, the ball screw converts the rotational power of the second motor 21 into linear movement of the nut member as the connecting portion 224.

  The connecting plate 23 has a shape extending in the thickness direction T so as to transmit the driving force of the second motor 21 to the door end portion 45. The end of the connecting plate 23 on the belt 223 side is connected to the belt 223 by the connecting portion 224 described above. The connecting part 224 is fixed to the belt 223. The end of the connecting plate 23 on the door end portion 45 side is fixed to the door end portion 45 by a fixing member 225.

[Operation of electric folding door device]
Operation | movement of the electric folding door apparatus 1 is demonstrated. For example, when the user issues an opening operation command or a closing operation command for the folding door 40 using an operation means such as a remote controller, the first controller 71 and the second controller 72 cause the folding door 40 to open or close. The first motor 11 and the second motor 21 are controlled.

(Opening operation from the closed state)
As shown in FIGS. 3 and 4, when the folding door 40 is in the closed state, the suspension door 41 and the door-end door 42 are arranged in a straight line in a plan view. When the folding door 40 is operated in the opening direction from the closed state, the folding door 40 does not operate in the opening direction only by applying a force to the door-end door 42 to pull the door-end portion 45 of the door-end door 42 in the width direction W. When the folding door 40 is operated from the closed state in the opening direction, it is necessary to apply a force to the suspension door 41 so that the suspension door 41 swings around the axis A1. In particular, when the open / close resistance is large, such as the folding door 40 to which the airtight packing 60 is attached or the folding door 40 attached to the opening 50 having a large opening width, it is large to swing the suspension door 41. Power is needed.

  In the first opening / closing device 10 of the present embodiment, the arm 13 is rotated about the axis A4 by the force increased by the power booster 12 as described above. The arm 13 that is rotated by the increased force swings the suspension door 41 about its axis A1. At this time, the first controller 71 and the second controller 72 may start the rotation of the first motor 11 and the rotation of the second motor 21 at the same time, and the rotation of the first motor 11 first. After starting, the rotation of the second motor 21 may be started thereafter.

  After the folding door 40 starts to move from the closed state to the opening direction, for example, as shown in FIG. 5, after the suspending door 41 and the door-end door 42 are slightly bent, the second motor 21 is opened. By generating a force to move the door tip portion 45 of the front door 42 in the width direction W of the opening 50, the door tip portion 45 moves in a direction approaching the suspension door 41, and is shown by a two-dot chain line in FIG. As shown in the perspective view of FIG. 7, the folding door 40 can be fully opened.

(Closed operation from fully open state)
As shown in FIGS. 4 and 7, when the folding door 40 is in a fully open state, the suspension door 41 and the door-end door 42 are arranged in a V shape that is nearly parallel in plan view. When operating the folding door 40 in the direction of closing the folding door 40 from the fully open state, it may not be sufficient to apply a force to the suspension door 41 so that the suspension door 41 swings around its axis A1. When the folding door 40 is operated from the fully open state in the closing direction, a force in the width direction W is applied to the door tip portion 45 such that the door tip portion 45 of the door door 42 is separated from the suspension portion 43 of the suspension door 41. Is preferred.

  In this embodiment, when such a pulling force in the width direction W is applied to the door end portion 45 by the second opening / closing device 20, the folding door 40 starts to move from the fully opened state to the closing direction, for example, as shown in FIG. As shown, the suspension door 41 and the door-end door 42 are slightly bent. When the folding door 40 is operated from such a state close to the closed state to the closed state, the folding door 40 is simply applied to the door end door 42 by a force that pulls the door end portion 45 of the door end door 42 in the width direction W. It is difficult to be in a closed state, and particularly when the opening / closing resistance is large, a large force is required to swing the suspension door 41. In this embodiment, when the folding door 40 is operated from the state close to the closed state as shown in FIG. 5 to the closed state shown by the solid line in FIGS. 3 and 4, the suspension door 41 is moved by the first opening / closing device 10. A force that swings around the axis A1 is applied to the suspension door 41. Thereby, the folding door 40 can be reliably closed.

[Summary of Embodiment]
The electric folding door apparatus 1 of the present embodiment outputs a force that swings the suspension door 41 around its axis A1 in order to operate the folding door 40 in a direction to open and close against a large resistance. And the 2nd function which outputs the force for operating the folding door 40 with the predetermined | prescribed moving speed after the operation | movement of the opening direction is started is implement | achieved using a separate motor. The first function is mainly realized by the first opening / closing device 10, and the second function is mainly realized by the second opening / closing device.

  Specifically, the first opening / closing device 10 is configured such that the force booster 12 increases the force generated by the first motor 11, and the arm 13 is rotated around the axis A4 by the increased force. Yes. Therefore, even when the folding door 40 is provided with an airtight packing 60, the suspension door 41 can be swung by the arm 13 whose rotating force is increased. The operation can be started in the direction of opening from the closed state. That is, the folding door 40 can be operated so as to exceed a so-called dead point when the folding door 40 is in the closed state.

  Then, when the folding door 40 starts to move from the closed state to the opening direction, and the suspension door 41 and the door-end door 42 reach a slightly bent state, the second motor 21 contacts the door-end of the door-end door 42. By generating a force that linearly moves the portion 45 along the width direction W of the opening 50 at a predetermined moving speed, the door tip portion 45 moves in a direction approaching the suspension door 41. By dividing the force required for opening and closing in this way into the first function and the second function, the operation until the folding door 40 reaches the fully open state can be made smooth. The predetermined moving speed means a speed at which the first motor 11 and the second motor 21 can be optimally synchronized for opening and closing.

  As described above, in this embodiment, since two motors are used for each function and the output of the first motor 11 is increased by the booster 12, each motor is reduced in size while reliably opening and closing the folding door 40. Can be As a result, the entire electric folding door apparatus can be made compact. Further, in the present embodiment, the first opening / closing device 10 and the second opening / closing device 20 provided separately are also provided with a degree of freedom of arrangement in which the first opening / closing device 20 and the second opening / closing device 20 can be arranged at positions suitable for exhibiting the respective functions. . Furthermore, since the arm 13 is used as a member for swinging the suspension door 41 in the first opening / closing device 10, the folding door 40 can be swung with a simple configuration in which the arm 13 is rotated. Therefore, for example, by applying the electric folding door device 1 of the present embodiment to a manual folding door, the manual folding door can be easily electrified.

  In the present embodiment, the first motor 11 is disposed closer to the folding door 40 than the second motor 21 in the thickness direction T of the folding door 40 in the closed state. Therefore, compared with the case where the 2nd motor 21 is arrange | positioned at the folding door 40 side rather than the 1st motor 11, the arm 13 which makes the suspension door 41 swing can be shortened. Thereby, since the torque for swinging the suspension door 41 can be reduced, it is possible to suppress an increase in output required for the first motor 11. As a result, the first opening / closing device 10 can be made compact.

  In the present embodiment, the second opening / closing device 20 guides the connecting plate 23 in the width direction W extending in the thickness direction T so as to transmit the driving force of the second motor 21 to the door end portion 45.

And a portion 232 extending toward. Since the connecting plate 23 has an L-shaped portion in this way, the arm 13 and the connecting plate 23 are arranged so as to overlap in a side view in order to make the height direction V compact. Moreover, it can suppress that the connection plate 23 interferes with the arm 13.
