Description

Hybrid balancing door device { HYBRID BALLENCING DOOR DEVICE}

The present invention relates to a balancing door device, and more particularly, to a hybrid balancing door device capable of opening a door by both manual opening and automatic opening driven by a motor.

Generally used doors are largely divided into sliding doors and opening doors. The sliding door opens and closes the entrance by moving the door in the lateral direction, and the swinging door opens and closes the entrance by rotating 90° back and forth about the hinge axis.

The sliding door has a disadvantage in that it requires a space for accommodating the door moved when the door is opened. Therefore, in places such as the entrance of a building, a hinged door is generally used.

However, even in the case of the retractable door, there is a disadvantage that a space corresponding to the rotation radius in the opening direction of the door must be secured in order for the door to be completely opened by rotating about the hinge axis.

In addition, in the case of a retractable door, when the wind blows toward the door, the door must rotate while facing the headwind, so there is a disadvantage that additional force is required to overcome the headwind when opening the door.

A balancing door is known as a solution to the disadvantages of such a conventional hinged door.

The balancing door is a type in which one end of the door arm is coupled to a pivoting point of the door arm formed on one side of the door frame, and the other end of the door arm is rotatably connected to a hinge located inside the side end of the door. The rotation of the door arm about the pivoting point of one side of the arm and the rotation of the door about the hinge part of the other end of the door arm are combined to open the door.

This operation of the door in the balancing door minimizes the turning radius when the door is opened, so it is easy to install in a narrow space before and after and reduces the force required to open the door. On the other hand, since the space between one side of the door frame and the one side end of the door is opened when the door is opened, it is possible to flow wind in both side directions of the door, so it is possible to reduce the resistance of the wind acting when the door is opened. There is this.

On the other hand, such a conventional balancing door is implemented only in a manual opening type and is not implemented in an automatic opening type, so there is a problem in that it cannot be used as a door applied to an exit of a building according to the Building Act.

Referring to the drawings, the door rotation shaft 10 is coupled to the door 2 via the upper and lower door arms 30 .

The upper door arm 20 is a member having a predetermined length, and one end thereof is coupled to rotate together with the door rotation shaft 10 . The other end is rotatably coupled to the upper door hinge 13 provided at a position spaced apart from the side end of the door 2 in the rear upper portion 200 of the door 2 .

Since the insertion block 21 is inserted into the hollow 11 of the door rotation shaft 10 , it is formed in the same cylindrical shape as the hollow 11 of the door rotation shaft 10 . At one end of the upper door arm 20 , a plurality of, for example, three coupling holes 22 starting from the lower end of the insertion block 21 and passing through one end of the upper door arm 20 in the extending direction of the insertion block 21 . ) is formed. The three coupling shafts 43 of the shaft fixing member 40 may penetrate through the coupling holes 22 to be coupled. Accordingly, the coupling holes 22 are formed to correspond to the coupling shafts 43 .

The protrusion shaft 23 provided at the other end of the upper door arm 20 extends in the same direction as the extension direction of the insertion block 21 . When the protrusion shaft 23 is formed as a separate member to be coupled to the upper door arm 20 in the form of a part, a shaft hole 24 is formed at the other end of the upper door arm 20, and the shaft hole 24 The protrusion shaft 23 is inserted and coupled.

The lower door arm 30 has a predetermined length corresponding to the upper door arm 20 , and the lower door arm 30 has an insertion block 31 at one end and a protrusion shaft 32 at the other end. (See Fig. 10).

The shaft fixing member 40 is disposed in the hollow 11 of the door rotation shaft 10 to operatively couple the door rotation shaft 10 , the upper door arm 20 and the door closer 50 .

The shaft fixing member 40 includes a cylindrical body 41 corresponding to the hollow 11 of the door rotation shaft 10 and a plurality of, for example, three coupling shafts 43 extending from the body 41 . .

The three coupling shafts 43 are spaced apart at equal intervals with respect to the center of the extending direction surface of the body 41 and are arranged in an annular shape. That is, the center of the coupling shaft 43 is shared with the center of the body 41 and is arranged to form a vertex of an equilateral triangle.

The coupling shafts 43 penetrate the coupling holes 22 of the upper door arm 20 to be coupled to the door closer 50 , and since the body 41 is inserted and coupled to the door rotation shaft 10 , the shaft fixing member ( 40 , it is possible to operatively couple the door rotation shaft 10 , the upper door arm 20 , and the door closer 50 .

Two screw holes 42 spaced apart from each other in the longitudinal direction are formed on the outer peripheral surface of the body 41 of the shaft fixing member 40 . A fixing hole 12 is formed on the outer peripheral surface of the upper part of the door rotation shaft 10 in the longitudinal direction, and the screw 44 is coupled to the screw hole 42 through the fixing hole 12, so that the shaft fixing member 40 is fixed. It is possible to adjust and fix the position inside the door rotation shaft 10 .

Since three coupling shafts 43 of the shaft fixing member 40 are provided at the vertex positions of the equilateral triangle, the force is not concentrated to one side during rotation, and it is possible to be appropriately distributed and transmitted. The coupling shaft 43 serves as a coupling element between the parts and a force transmission element.

The door closer 50 includes a closer body 51 , a rotation support shaft 52 , an actuator 54 , and an operation link 56 .

The closure body 51 is provided with a rotation support shaft 52 on one side, and an actuator 54 is installed on the other side.

The rotation support shaft 52 is coupled to the upper door arm 20 by the shaft fixing member 40 . The rotation support shaft 52 is rotatably installed on the closure body 51 . 7 illustrates a form in which the rotation support shaft 52 is rotatably supported by a bearing and installed in the closer body 51 .

A coupling hole 53 corresponding to the coupling hole 22 formed in the upper door arm 20 is formed through the rotation support shaft 52 . Accordingly, the coupling shaft 43 of the shaft fixing member 40 penetrates the coupling hole 22 of the upper door arm 20 and is inserted into the coupling hole 53 of the rotation support shaft 52 , so that the upper door arm 20 ) and may be coupled to rotate integrally.

According to the present invention, since each of the three coupling shafts 43 is inserted through an independent coupling hole 22, even if a tolerance occurs between any one coupling shaft 43 and the coupling hole 22 corresponding thereto, By the coupling of the other two coupling shafts 43 and the coupling hole 22, the clearance may be offset by the tolerance. That is, a coupling can be made in which play is minimized in coupling between the door rotation shaft 10 , the upper door arm 20 , and the rotation support shaft 52 .

A middle portion of the rotation support shaft 52 is exposed to the outside so that the rotation support shaft 52 is engaged with the operation link 56 . Therefore, it can be understood that the rotation support shaft 52 is rotatably installed between the upper plate and the lower plate supporting the upper and lower portions of the rotation support shaft 52 in the closure body 51 .

The upper surface of the closer body 51 is spaced apart from the rotation support shaft 52, the actuator 54 is installed on the other side. Actuator 54 may be a known hydraulic or pneumatic cylinder type, and is a driving mechanism that provides a force to automatically close the door 2 when the force to open the door 2 is removed.

A rotation shaft 55 protrudes from the actuator 54 in the lateral direction. The actuator 54 controls the rotation of the rotating shaft 55 , when a force is applied to the rotating shaft 55 , the rotating shaft 55 rotates, and when the applied force is removed, the rotating shaft 55 is moved to its original position by the actuator 54 . return to By using the movement control of the rotary shaft 55 by the actuator 54, the door 2 can be automatically closed slowly in the open state.

An actuating link 56 is installed in the closure body 51 to transmit movement between the rotation support shaft 52 and the rotation shaft 55 of the actuator 54 .

The operation link 56 is connected between the rotation support shaft 52 and the rotation shaft 55 of the actuator 54 via the first and second link connecting members 56a and 56b. One end of the first and second link connecting members 56a and 56b is fixedly connected to the rotation support shaft 52 and the rotation shaft 55 of the actuator 54, respectively, and the other end is the operation link 56, one end and the other end, respectively. is rotatably connected to The rotation support shaft 52 and the rotation shaft 55 of the actuator 54 are operatively connected by the first and second link connecting members 56a and 56b.

According to the present invention, since the extension direction of the rotation support shaft 52 and the extension direction of the rotation shaft 55 of the actuator 54 cross each other, one end is fixed to the rotation shaft of the rotation support shaft 52 and the actuator 54 The rotation radii of the combined first and second link connecting members 56a and 56b are respectively located in planes intersecting with each other. Referring to FIG. 3 , the rotation support shaft 52 rotates about the z-axis direction, and the rotation shaft 55 of the actuator 54 is set to rotate about the y-axis direction.

When the door rotation shaft 10 rotates when the door 2 is opened and the rotation support shaft 52 rotates clockwise about the z-axis, the first link connecting member 56a rotates the rotation support shaft 52 . Since they are coupled to rotate together, the first link connecting member 56a also rotates clockwise about the z-axis. As a result, the operation link 56 is pulled, so that the second link connecting member 56b rotates clockwise along the y-axis together with the rotation shaft 55 . After the door 2 is opened, when a person releases the hand holding the door 2 and the force to move the door 2 is removed, the rotation shaft 55 of the actuator 54 returns to the second link connecting member. Returning to the original position while rotating (56b) counterclockwise around the y-axis, the second link connecting member (56b) pulls the actuating link 56 in the opposite direction, so that the first link connecting member (56a) rotates the supporting shaft ( 52) and rotates counterclockwise around the z-axis to drive the door rotation shaft 10 to close the door 2 .

According to the present invention, a connection relationship for returning the door 2 to the closed position is made inside the door closer 50 , and the door 2 is directly connected to the door closer 50 in addition to coupling with the door arms 20 and 30 . Since the door 2 is not connected to each other, it is easy to install the door 2 , and there is no need to form a gap for the installation of the members between the door 2 and the door frame 1 .

9 is a view for explaining the coupling relationship between the door rotation shaft 10 and the lower door arm 30 in the hybrid balancing door apparatus according to the present invention.

The lower support 34 is positioned at the lower end of the door rotation shaft 10 , has a protruding shaft 35 protruding upward, and is fixed to the floor surface.

The rotating groove 33 includes a rotating element such as a bearing.

After fixing the lower support 34 to the bottom surface during construction, the protrusion shaft 35 is inserted into one end of the rotation groove 33 of the lower door arm 30 to install the lower door arm 30 . Thereafter, the door rotation shaft 10 is coupled so that the insertion block 31 of the lower door arm 30 is inserted into the hollow 11 of the door rotation shaft 10 .

The other end protrusion shaft 32 of the lower door arm 30 is rotatably coupled to the lower door hinge 14 fixed to the lower part of the door under the door 2 . The protrusion shafts 23 and 32 of the upper door arm 20 and the lower door arm 30 are coupled to the upper and lower door hinges 13 and 14 of the upper and lower portions of the door 2 so as to be disposed in opposite directions. . Accordingly, the lower door arm 30 is coupled to the lower door hinge 14 under the door 2 to mount the door 2 on the lower door arm 30, and then the other end protrusion shaft of the upper door arm 20 ( The door 2 is assembled in such a way that 23) is coupled with the upper door hinge 13 of the door 2 .

1, 2, and 10, the hybrid balancing door device according to the present invention includes a door opening driving device 60, which allows the door 2 to be opened automatically.

According to the embodiment of the present invention, the door opening driving device 60 includes a driving motor 61 and an operating arm 63 . It also includes a control board 69 for controlling the operation of the drive motor 61 .

The drive motor 61 is provided in the door frame 1 .

The driving motor 61 is driven by a door opening signal generated by a door switch (not shown) for automatic opening of the door 2 . In order to drive an automatic door, a button-type door switch is generally installed on a door, a door frame, or near a door, and when a user presses the door switch, a door open signal is generated, thereby automatically opening the door. The door open signal can be generated by a sensor installed near the door to detect a person.

One side of the operating arm 63 is rotatably connected to the connecting shaft 62 of the driving motor 61 . The connecting shaft 62 becomes the rotation center of the actuating arm 63 .

An actuating arm 63 is provided for pushing the door 2 open. The operating arm 63 rotates by the driving of the driving motor 61 , while the other end pushes the upper part 200 of the door 2 to rotate the door 2 to the open position.

In the hybrid balancing door device according to the present invention, the door arm (20,30) rotates with the door rotation shaft (10) as a pivot point and the door (2) is a door where the other ends of the door arms (20,30) are connected. The operation of rotating around the hinges 13 and 14 is combined to open the door 2 while minimizing the rotation radius. Accordingly, when the operating arm 63 is rotated by the drive motor 61 and the other end of the operating arm 63 pushes the door 2, the abutting position of the other end of the operating arm 63 and the door 2 moves. do. When the operating arm 63 rotates, the roller 64 rotates while in contact with the door upper part 200 to perform a rolling motion. This allows the opening operation of the door 2 by the actuating arm 63 to be performed smoothly and with minimal noise.

The control board 69 is provided to control the operation of the driving motor 61 . The control board 69 drives the driving motor 61 by the door open signal of the door switch to rotate the operating arm 63 in one direction. Thereby, the door 2 is pushed open while the operation arm 63 rotates.

In addition, the control board 69 generates a door closing signal after the door 2 is fully opened and before the door 2 is closed by the door closer 50, so that the operating arm 63 returns to its original position. It rotates in the opposite direction of the drive motor 61 .

Since the other end of the actuating arm 63 is not engaged with the door 2 and opens the door 2 in a pushing manner, when returning to the original position, the actuating arm 63 is returned by the door 2 motion is not disturbed.

Further, when the door 2 is automatically closed by the door closer 50 after the lapse of a predetermined time in the open position, the operating arm 63 does not interfere with the operation of the door 2 being closed by the door closer 50 does not

However, even in this case, the operation coincides only in time, and the operating arm 63 is returned by the drive motor 61 , the door 2 is returned by the door closer 50 , and the operating arm 63 is returned by the door closer 50 . Since this door 2 is located in front of the path to be closed, in practice the actuating arm 63 corresponds to returning before the door is closed. That is, the operating arm 63 returns to no-load and is not controlled by the closing operation of the door 2 .

According to the embodiment of the present invention, the driving motor 61 is installed on one side of the door closer 50 on the upper door frame 1 , and the operating arm 63 is extended on one side and the other side of the door upper part 200 . It is disposed in the receiving groove 230 between the 210 and 220 and is connected to the driving motor 61 through the connecting shaft 62 .

One extension part 210 has a cutout ( 211) may be formed.

The cutout 211 is cut by a length corresponding to the turning radius of the actuating arm 63 when the door 2 of the actuating arm 63 is opened so that the rotating actuating arm 63 does not interfere with the extension 210 on one side. It is possible to pass without In this arrangement, the operating arm 63 rotates the door 2 by pushing the other extension 220 of the door upper portion 200 . The other end roller 64 of the operating arm 63 rotates and rolls while in contact with the inner surface of the other extension part 220 .

According to the embodiment of the present invention, a stopper 65 for guiding the return position of the operating arm 63 is provided in the door frame 1 . The stopper 65 causes the operating arm 63 to return to the initial stop position when the operating arm 63 is rotated by the driving motor 61 to return to the original state after opening the door 2 . The stopper 65 is installed at a position where the other end roller 64 of the operating arm 63 contacts at the initial stop position.

According to the embodiment of the present invention, the driving motor 61 is installed in the upper door frame 1 , and the operating arm 63 is a receiving groove 230 between one side and the other extension parts 210 and 220 of the upper door part 200 . ), the driving motor 61 and the operating arm 63 are prevented from being exposed in a non-operational state, thereby making it aesthetically pleasing. In addition, it is possible to prevent the actuating arm 63 from being exposed to the outside at the initial stop position, thereby preventing the actuating arm 63 from being damaged.

The door opening drive device 60 according to the present invention can change the manual opening type balancing door device to a hybrid opening method in which manual opening and automatic opening are selectively possible with a simple configuration.
