The rotary motor 73 and the second door assembly 2 are moved in the vertical direction along the rack 71 when the rotary motor 73 rotates the pinion 72 .

That is, when the pinion 72 is rotated by driving the rotation motor 73 provided in the right vertical frame 502, the driving force that the pinion 72 can move in the vertical direction along the rack 70, A driving force capable of moving the right side of the second door assembly 2 in the vertical direction is generated. At this time, the generated driving force can be transmitted by the driving force transmitting assembly 30 to move the left side of the second door assembly 2 in the vertical direction.

Meanwhile, the first door assembly 1 and the third door assembly 3 are coupled to the second door assembly 2 in the manner shown in FIGS. 5A through 6. At this time, when the first door assembly 1, the second door assembly 2, and the third door assembly 3 move in the vertical direction, the moving speed of the first door assembly 1 is lower than the moving speed of the second door assembly 2, And the moving speed of the second door assembly 2 may be smaller than the moving speed of the third door assembly 3. A concrete configuration for this will be described later.

As shown in FIG. 6, the upper and lower ends of the second mounting portions 201 and 202 are formed with the slide axes 141 and 142 for the pulleys 131 and 132, respectively. The pair of pulleys 131 and 132 may be rotatably coupled to a pair of left and right axles 141 and 142. The belt 133 may be engaged with the outer circumferential surfaces of the pair of pulleys 131 and 132.

A first engaging portion 51 is formed at one point of the third attaching portions 301 and 302. The first engaging portion 51 is engaged with the first portion of the belt 133 As shown in Fig. A third engaging portion 53 is formed at one point of the first mounting portions 101 and 102. The third engaging portion 53 is engaged with the second portion of the belt 133 As shown in FIG.

At this time, in one embodiment of the present invention, the pair of pulleys 131 and 132 and the belt 133 may be collectively referred to as the " movable pulley assembly 140 ".

The power transmission principle between the first mounting portions 101 and 102, the second mounting portions 201 and 202, and the third mounting portions 301 and 302 will be described below.

The second moving parts 211 and 212 movably coupled to the second rails 221 and 222 when the pinion 72 moves in the vertical direction along the rack 71 by driving the rotation motor 73, So that it can move in the vertical direction. At this time, the second moving parts 211 and 212 are fixedly coupled to the second mounting parts 201 and 202, respectively, and the first part 52 of the belt 133 is fixed to the first moving parts 211 and 212, And the third engaging portions 53 of the first mounting portions 101 and 102 are engaged with the second portions 53 of the belts 133. Therefore, The first mounting portions 101 and 102 and the third mounting portions 301 and 302 coupled to the belt 52 can be moved in the same direction as the second mounting portions 201 and 202. [ That is, as the second door assembly 2 moves in the vertical direction, the first door assembly 1 and the third door assembly 3 can move in the same direction. The first door assembly 1 moves at a slower speed than the second door assembly 2 and the second door assembly 2 moves at a slower speed than the third door assembly 3.

In the meantime, in the screen door apparatus 100 according to the embodiment of the present invention, when no electric power is supplied to the rotary motor 73, or when the rotary shaft of the rotary motor 73 is freely rotatable by an external force It is possible to provide a structure in which the door assemblies 1, 2 and 3 can be vertically opened and closed manually.

Hereinafter, with reference to FIGS. 7A and 7B, the principle of the manual opening and closing operation will be described in the screen door apparatus 100 according to the embodiment of the present invention.

7A and 7B are views for explaining a manual opening / closing operation principle in the screen door apparatus 100 according to an embodiment of the present invention. FIG. 7A shows a state in which the second door assembly 2 is closed, and FIG. 7B shows a state in which the second door assembly 2 is opened.

7A and 7B, the screen door apparatus 100 according to an embodiment of the present invention may further include a pulley 34, a piston 61, and a cylinder 62. [ At this time, in one embodiment of the present invention, the piston 61 and the cylinder 62 may be referred to collectively as the 'piston-cylinder assembly 60'.

A cylinder 62 extending in the vertical direction may be fixed to the right vertical frame 502. A piston 61 may be movably coupled to the inside of the cylinder 62 in a vertical direction along the inside of the cylinder 62. A pulley 34 may be coupled to one side of the piston 61, for example, the upper end of the piston 61.

And the connecting hole 21 may be engaged with the outer peripheral surface of the pulley 34. [ One end of the connecting hole 21 is fixedly connected to one point of the right connecting part 42 included in the second door assembly 2 and the other end of the connecting hole 21 is connected to a lower end of the right vertical frame 502. [ May be fixedly connected to one point of the < RTI ID = 0.0 >

At this time, the position of the pulley 34 may always be located at one end of the connector 21 and at a higher position than the other end.

At this time, the connector 21 may have a deformable shape, and the total length of the connector 21 may be constant. At this time, the connector 21 may be embodied using a metal rope, a belt, a chain, or the like. At this time, in one embodiment of the present invention, the connector 21 may be referred to as the term " mutual force transmission connector 21 ".

According to such a configuration, the pressurized fluid in the cylinder 61 can be transmitted by the connector 21 so that the upward force for raising the piston 62 can act in the upward direction with respect to the second door assembly 2. [ Conversely, a downward force acting downward by the mass of the second door assembly 2 can be transmitted to the piston 62 by the connector 21 so as to compress the fluid in the cylinder 61. At this time, if the upward force and the downward force are designed to be in equilibrium, a person can easily lift or lower the second door assembly 2. Therefore, manual opening and closing can be smoothly performed.

The second door assembly 2 shown in Figs. 7A and 7B is provided with a first door assembly 1 and a third door assembly 3 by a coupling structure as shown in Figs. 5A to 6, . This increases the lowering force acting downward by the masses of the first door assembly 1, the second door assembly 2, and the third door assembly 3. Therefore, in order to balance the uplifting force and the lowering force described above, it is possible to design the pressurizing fluid in the cylinder 61 to have a greater lift force for lifting the piston 62.
