Referring to FIGS. 1 to 9 , a semi-automatic device 100 for a door according to an embodiment of the present invention is inserted into a door frame 20 connected to the door 10 . Here, the door 10 is used as a meaning encompassing all sliding doors, casement doors, and interlocking doors. The semi-automatic device 100 is preferably formed in a size capable of moving along a rail inside the door frame 20 . In this case, the number of doors 10 may be one or more. The semi-automatic device 100 can also be used for three or more doors 10. The semi-automatic device 100 may be positioned horizontally with the top of the door 10 or positioned horizontally with the side of the door 10. In other words, the semi-automatic device 100 may be formed on the top or side of the door frame 20 . This is to reduce the space on the side of the door frame 20 by minimizing the volume. The semi-automatic device 100 is fixed to the door frame 20 with bolts, and its position can be varied.

More specifically, the semi-automatic device 100 for a door according to an embodiment of the present invention includes a fixing plate 110, a moving plate 120, a length adjusting unit 130, and a wire 140. In this case, the semi-automatic device 100 may include a fixing plate 110, a moving plate 120, a length adjusting unit 130, and a wire 140 inside the square body frame 100-1.

The fixing plate 110 is positioned horizontally on one side of the body frame 100-1. The fixing plate 110 may be formed of a metal material, and a plurality of through holes may be perforated. A plurality of first pulleys 111 are formed on the fixing plate 110 . In this case, a wire 140 to be described later is wound around the plurality of first pulleys 111 . The plurality of first pulleys 111 are formed so that the central axis is perpendicular to the fixing plate 110. In other words, the first pulleys 111 are positioned horizontally with the body frame 100-1. A plurality of first pulleys 111 may be formed on one side or the other side of the fixing plate 110 . The fixing plate 110 is fixed to the door frame 20 and its position is maintained.

In addition, a first guide roller 112 may be formed on one side of the fixing plate 110 . In this case, the fixing plate 110 may be formed in a stepped shape on one side. The central axis of the first guide roller 112 is formed in a horizontal direction with the fixing plate 110 . A groove may be formed in the center of the first guide roller 112 to allow the wire 140 to be wound. In this case, the portion where the first guide roller 112 is located in the fixing plate 110 is formed to pass through. The first guide roller 112 serves to guide the wire 140 located on one side of the fixing plate 110 to the other side. This is to connect the door 10 and the wire 140 in a minimum space while the fixing plate 110 is positioned in the horizontal direction with the door 10 .

In addition, a first closing cap 113 may be connected to one side of the fixing plate 110 . The first closing cap 113 may be formed of a synthetic resin material or a metal material. The first closing cap 113 is coupled to one end of the fixing plate 110 to prevent the first guide roller 112 from being separated from the fixing plate 110 . In this case, the first closing cap 113 may be fixed to the fixing plate 110 and bolts, but is not necessarily limited thereto. A coupling hole 113-1 is formed in the first closing cap 113 so that it can be bolted to the door frame 20. Accordingly, the fixing plate 110 may be coupled to the door frame 20 at a position horizontal to the door 10 .

The moving plate 120 is positioned horizontally on one side of the body frame 100-1. The moving plate 120 is formed to be spaced apart from the fixed plate 110 at a predetermined interval. The moving plate 120 may be formed of a metal material, and a plurality of through holes may be perforated. A plurality of second pulleys 121 are formed on the moving plate 120 . In this case, a wire 140 to be described later is wound around the plurality of second pulleys 121 . The plurality of second pulleys 121 are formed so that their central axes are perpendicular to the moving plate 120 . In other words, the second pulleys 121 are positioned horizontally with the body frame 100-1. A plurality of second pulleys 121 may be formed on one side or the other side of the moving plate 120 . The position of the moving plate 120 is changed by a length adjusting unit 130 to be described later.

Also, according to the number of the plurality of first pulleys 111 of the fixed plate 110 and the plurality of second pulleys 121 of the moving plate 120, the length of the wire 140 passing through them varies. In other words, the wire 140 is wound around different first pulleys 111 and second pulleys 121 while reciprocating between the plurality of second pulleys 121 of the plurality of first pulleys 111 . The operating distance of the wire 140 according to the variable length of the length adjusting unit 130 to be described later is varied according to the number of lines of the reciprocating wire 140 . For example, if the number of turns of the wire 140 is 4, the moving distance of the door 10 can be increased four times by being connected to the wire 140 compared to the variable length of the length adjusting unit 130 .

In addition, a second guide roller 122 may be formed on one side of the moving plate 120 . For example, the second guide roller 122 may be formed on the other side of the moving plate 120 . The second guide roller 122 can be moved by being inserted into the body frame 100-1. In this case, a rail for guiding the second guide roller 122 may be formed on the inner wall of the body frame 100-1. The second guide roller 122 is a synthetic resin roller into which bearings are inserted, and can minimize resistance and noise and minimize power loss during movement of the moving plate 120 .

One side of the length adjusting unit 130 is connected to the fixed plate 110 and the other side is connected to the moving plate 120 . For example, the length adjustment unit 130 may be implemented with an elastic spring inserted therein or a shock absorber that buffers pressure caused by an external force by hydraulic pressure. In other words, after being compressed by an external force, the length adjusting unit 130 is restored to its original position by a restoring force and the length is varied. In this case, the position of the fixing plate 110 connected to one side of the length adjustment unit 130 is not variable, but the position of the moving plate 120 is variable according to the length adjustment unit 130 . The length adjusting part 130 is compressed as the door 10 moves to be opened, and in this case, the impact is cushioned. The length adjusting unit 130 moves so that the door 10 is automatically closed while restoring its length in a state in which the external force is released.

One side of the wire 140 is connected to the door 10 and the other side is connected to the fixing plate 110 . For example, the wire 140 may be formed of a metal material. The wire 140 is wound while passing through the plurality of first pulleys 111 of the fixed plate 110 and the plurality of second pulleys 121 of the moving plate 120 . The wire 140 compresses the space between the fixed plate 110 and the moving plate 120 according to the movement of the door 10 . In this case, the length adjustment unit 130 connected between the fixed plate 110 and the moving plate 120 is also compressed. For example, when the door 10 is opened and moved by an external force, the door 10 is moved closed again by the restoring force of the length adjusting unit 130 so that it is automatically closed.

More specifically, one side of the wire 140 moves from one side of the fixing plate 110 to the other side by the first guide roller 112 of the fixing plate 110 and is connected to the door 10 . The other side of the wire 140 is wound around the plurality of second pulleys 121 located on the moving plate 120 through the plurality of first pulleys 111 of the fixed plate 110 . Subsequently, the wire 140 is again wound around the unwound first pulley 111 among the plurality of first pulleys 111 and then again wound around the unwound second pulley 121 among the plurality of second pulleys 121 do. After that, the wire 140 is fixedly connected to one side of the fixing plate 110 .

In addition, a first elastic spring 141 may be formed at a portion of the wire 140 connected to the fixing plate 110 . In other words, the first elastic spring 141 may be connected between the fixing plate 110 and the wire 140 . This is to minimize a phenomenon in which the wire 140 is stretched when the door 10 is artificially moved to close. In addition, the first elastic spring 141 may serve to provide an additional movement distance to the distance by the wire 140 when the length of the length adjustment unit 130 is changed. In addition, the first elastic spring 141 serves to prevent the wire 140 from being twisted. In this case, the length of the first elastic spring 141 may be varied by a user's setting.

In addition, the wire 140 may be bent and inserted into the groove of the fixing bolt 142 connected to the door 10, and the fixing screw 143 may be coupled to the fixing bolt 142 to be fixed. In this case, the fixing bolt 142 and the fixing screw 143 are threaded so that the wire 140 can be brought into close contact through screw coupling. The fixing bolt 142 may be bolted to the door 10 . A straight groove or a cross groove may be formed in the fixing screw 143 so as to be rotated and fixed.

In this case, as shown in FIG. 9 , the fixing bolt 142 may be formed on the door bracket 144 . The door bracket 144 is a member of a flat plate that is bolted to one side of the door. A plurality of bolt holes 144-1 may be formed in the door bracket 144, and a plurality of buffer rollers 144-2 may be coupled to the bolt holes 144-1. The plurality of buffer rollers 144 - 2 are rollers that contact and guide the inside of the door frame 20 . This is to allow the door 10 to slide along the inside of the door frame 20 . In this case, several bolt holes 144-1 may be drilled in order to mount the rollers in various positions according to the width or length of the door 10.

Meanwhile, as shown in FIGS. 7 and 8 , when the semi-automatic device 100 for a door is connected to the casement door 10, the rotation angle of the door 10 may be adjusted. For example, as shown in FIG. 7 , the door 10 may rotate at an angle of 90°. As shown in FIG. 8 , it is also possible to rotate the door 10 at an angle of 180°. In this case, a pair of first guide rollers 112 may be formed on the fixing plate 110 . This is to allow the wire 140 to be placed according to the direction in which the door 10 is rotated. In other words, the wire 140 is positioned between the pair of first guide rollers. In this case, the rotation support 30 is formed on the door frame 20 . The rotation support 30 rotates according to the rotation direction of the door 10 while the wire 140 is connected and supported. The rotation support 30 serves to prevent the wire from being twisted. Accordingly, the door 10 can be opened from 90° to 180° and automatically closed.

Meanwhile, the semi-automatic device 100 for a door according to an embodiment of the present invention may further include a shock absorber 150.

The buffer unit 150 is formed on one side of the moving plate 120 and serves to buffer an impact when the moving plate 120 moves. For example, the buffer unit 150 is formed of a second elastic spring 151 or an auxiliary length adjusting unit 152 implemented as a pneumatic shock absorber of the same type as the length adjusting unit 130. It could be. In this case, the second closing cap 123 may be connected to the other side of the shock absorber 150 . The second closing cap 123 is coupled to one side of the body frame 100-1 and its position is fixed. In this case, a coupling hole 113-1 is formed in the second closing cap 123 so that it can be bolted to the door frame 20.

In addition, while the buffer unit 150 is fixed by the second closing cap 123, a pulling force may act to restore it when the moving plate 120 moves. For example, when the door 10 is moved and the length adjustment unit 130 is compressed, the length of the buffer unit 150 is extended. When the external force of the door 10 is released, it is primarily moved to its original position by the restoring force of the length adjusting unit 130, and secondarily moves to its original position more easily by the buffer unit 150. . Accordingly, after the door 10 is opened, the door 10 can quickly return to its original position.

FIG. 10 is an exemplary view for explaining that a stopper is added to the semi-automatic device for a door according to FIG. 1 .

1 to 10, the semi-automatic device 100 for a door according to an embodiment of the present invention may further include a stopper 160.

The stopper 160 moves by being coupled with the moving plate 120 by a magnetic force. In this case, magnets may be formed on one side of the moving plate 120 and one side of the stopper 160, respectively. The stopper 160 moves together with the moving plate 120 . The stopper 160 may be fixed to the body frame 100-1 through fastening bolts 161 when the door 10 is forcibly kept open. In this case, it is preferable that a long hole is formed in the lower part of the body frame 100-1 so that the fastening bolt 161 can be inserted. When the stopper 160 is fixed to the body frame 100-1, the movement of the moving plate 120 is restricted so that the movement of the door 10 stops and the open state can be maintained. Accordingly, when the door 10 needs to be opened for a long time, the open state can be easily maintained using the stopper 160 .

11 and 12 are exemplary views illustrating the addition of an interlocking unit to the semi-automatic door device according to FIG. 1 .

1 to 12 , the semi-automatic device 100 for a door according to an embodiment of the present invention may further include an interlocking unit 170.

The interlocking unit 170 moves the plurality of doors 10 by interlocking with each other. In this case, the plurality of doors 10 may be implemented as a first door 11 whose position is fixed, a second door 12 located in the middle and moving, and a third door 13 which is movable. The interlocking part 170 is formed on the upper part of the second door 12 . The interlocking unit 170 allows the second door 12 to interlock and move when the third door 13 moves. In this case, one side of the wire 140 is connected to the second door 12 or the interlocking part 170 . In other words, when the third door 13 moves in the direction of opening, the second door 12 is pulled to restore its position. In this case, the body frame 100-1 of the semi-automatic device 100 is located on the door frame 20 on the line where the first door 11 is located, and one side may be connected to the first door 11. In addition, the first guide roller 112 is installed on one surface of the fixed plate 110 on the same plane as the plurality of first pulleys 111, and one side is formed protruding from the fixed plate 110. This is to connect the second door 12 and the wire 140 moving along the other neighboring rail on the same rail.

More specifically, the interlocking unit 170 includes the bottom plate 171, the first pulley 172, the second pulley 173, the chain 174, the first guide unit 175 and the first guide unit 176 includes The bottom plate 171 is a frame in the longitudinal direction, and an insertion hole is formed on one side. A pivot fixed to the second door 12 is inserted into the insertion hole and connected to the bottom plate 171 . A first pulley 172 , a second pulley 173 , a first guide part 175 , a first guide part 176 , and a chain 174 are positioned above the bottom plate 171 . The first pulley 172 and the second pulley 173 are formed to be spaced apart from both sides of the bottom plate 171 as a kind of rotating body. The first pulley 172 and the second pulley 173 are positioned and rotated in a direction parallel to the bottom plate 171 . The first pulley 172 and the second pulley 173 are rotated in conjunction with each other by a chain 174 to be described later.

The chain 174 of the interlocking unit 170 is formed as a closed loop to connect the first pulley 172 and the second pulley 173 . The chain 174 may be formed of a metal material or a synthetic resin material. The chain 174 allows the first pulley 172 and the second pulley 173 to rotate in conjunction with each other. A first guide part 175 and a first guide part 176 are formed on both sides of the chain 174 . The first guide part 175 and the first guide part 176 are connected to the chain 174 and rotate. The first guide part 175 and the first guide part 176 are connected to the pivot of the first door 11 and the pivot of the third door 13, respectively. Accordingly, the first door 11, the second door 12 and the third door 13 are interlocked with each other. The first guide part 175 and the first guide part 176 are spaced apart from each other on the chain 174 and move in opposite directions. The movement range of the first guide part 175 and the first guide part 176 is limited by the first pulley 172 and the second pulley 173 .

The movement of the first door 11, the second door 12, and the third door 13 according to the interlocking unit 170 will be described as follows. When the third door 13 in a closed state moves in an open direction by an external force, the first guide part 175 moves, and accordingly, the opposite first guide part 176 moves in the opposite direction by the chain 174. will move to In this case, the first guide part 175 moves until it contacts the first pulley 172, and in the case of the first guide part 176, since the first door 11 is fixed, the second The door 12 also moves in the same direction as the third door 13. In this case, while the wire 140 connected to the second door 12 is pulled, the length adjustment unit 130 is compressed.

Next, when the external force is released on the third door 13, the length adjustment unit 130 pulls the second door 12 to its original position while restoring it to its original position. In this case, while the second door 12 moves, the chain 174 rotates, and the first guide unit 175 connected to one side moves. As the first guide part 175 moves to its original position, the third door 13 connected thereto also moves in the closing direction. Accordingly, the three doors move in conjunction with each other, and at the same time, the door 10 can be closed semi-automatically.

In the above, the present invention has been described with reference to the preferred embodiments described with reference to the drawings, but is not limited thereto. Therefore, the present invention should be interpreted by the description of the claims intended to cover obvious modifications that can be derived from the described examples.
