That is, even if not specifically stated, the following description about the first blind module 10 can be applied in the same way to the components of other blind modules including the second blind module.
  • the first blind module 10 includes the first frame 11, the first bar 12 rotatably combined with the first frame 11, the first screen 13 configured to be wound on or unwound from the first bar 12, and the first weight 14 disposed at the end of the first screen 13.
  • the first frame 11 receives and protects the first bar 12 therein, and as shown in FIGS. 6 and 7, it may have a length corresponding to the first bar 12.
  • the first frame 11 may have a coupling structure (first rail coupling portion 11a) at the upper end to be slidably coupled to the rail part described above and may be formed in various shapes in which the bar can be rotated.
  • the first bar 12 is rotatably coupled to a shaft. Both ends of the first bar 12 can be coupled through a rotary structure using a shaft.
  • the shaft structure rotatably fixing the first bar 12 may be implemented in various shapes. As shown in the figures, the first bar 12 can be rotated by coupling members 124 at both ends (e.g., rotatable rings on a support member at the center) and a shaft 123 with the first torsion spring 121 fitted thereon. That is, various shapes of shaft structures coupled to both ends of the first bar 12 and rotatably supporting the first bar 12 can be formed.
  • the first bar 12 may be a hollow pipe and a more compact coupling structure can be achieved using the internal space.
  • the first screen 13 is changed in length by being wound on or unwound from the first bar 12.
  • the first screen 13 is fixed to the outer side of the first bar 12 at the upper end, and is connected to the first weight 14 at the lower end to enhance tension.
  • the first bar 12 is rotated in a direction
  • the first screen 13 is wound up on the first bar 12 and the unwound part is shortened.
  • the first screen 13 is unwound down from the first bar 12 and the unwound part is increased in length. That is, the first screen 13 can be moved up and down by rotation of the first bar 12.
  • the first screen 13 may be made of fabric and may be made of various materials that can block light.
  • the first screen 13 stretches in the gravity direction from the outer side of the first bar 12.
  • the first screen 13 stretches in the tangential direction on the outer side of the first bar 12 and transmits load at the position spaced by the radius of the first bar 12 from the rotational center of the first bar 12. Accordingly, torque (first-directional torque T1) is applied to the first bar 12 by the load by the first screen 13.
  • the first bar 12 is rotated in the direction (first direction) in which the first screen 13 is unwound.
  • the rotational angle of the first bar 12 is increased, the unwound length of the first screen 13 is increased, and as the unwound length of the first screen 13 is increased, the load is also increased, so the torque applied to the first bar 12 by the first screen 13 is also increased.
  • the first torsion spring 121 is disposed in the first bar 12, as shown in the figures.
  • the first torsion spring 121 is compressed or relaxed while rotating with the first bar 12.
  • the first torsion spring 121 may be a torsional elastic body that stores elastic energy by being elastically deformed with rotation of the first bar 12, and the torsional elastic body may be a coil spring.
  • Both ends of the first torsion spring 121 may be connected to a rotary block 122 and a fixed portion 123a of the shaft 123, respectively.
  • the rotary block 122 rotates with the first bar 12 and the fixed portion 123a keeps fixed, whereby torsion of the first torsion spring 121 can be caused.
  • the shaft 123 can rotatably support the first bar 12 using a rotary ring 123b fitted on the fixed portion 123a.
  • the shaft 123 is disposed through the rotational center of the rotary block 122 and the outer side of the rotary block 122 is coupled to a running guide 120a on the inner side of the first bar 12, so the rotary block 122 can synchronously rotate with the first bar 12.
  • An end of the shaft 123 can be fixed to the first frame 11. According to this structure, when the first bar 12 is rotated, the rotary block 122 is correspondingly rotated and a first end of the first torsion spring 121 connected to the rotary block 122 can be twisted and deformed.
  • the shaft 123 rotatably supports the first bar 12 but doesnot rotate by itself, so a second end of the torsion spring 121 fixed to the shaft 123 keeps fixed.
  • the first torsion spring 121 can be configured in this way.
  • the way of configuring the first torsion spring 121 is not necessarily limited thereto and the installation structure of the first torsion spring 121 may be changed in other ways that can apply torque by applying elasticity to the first bar 12.
  • the amount of deformation of the first torsion spring 121 is increased in correspondence to rotation of the first bar 12, and accordingly, the restoring force is also increased.
  • the restoring force is applied in the opposite direction to the rotation which caused deformation, so torque is generated in the opposite direction to the rotational direction of the first torsion spring 121. That is, torque (second-directional torque T2) is applied to the first bar 12 by the first torsion spring 121 in the opposite direction to the torque applied by the first screen 13 and the first weight 14.
  • the first bar 12 is rotated in the direction (first direction) in which the first screen 13 is wound by the torque.
  • the torque that is applied to the first screen 13 and the first weight 14 when the first bar 12 is rotated and the torque that is applied to the first bar 12 by the first torsion spring 121 are increased in opposite directions while keeping balance. Accordingly, the balance can be maintained by matching the increments of the torque and the first bar 12 can be stopped at any position. That is, as shown in FIG. 6, when the first screen 13 is unwound, a pair of torque in opposite directions is increased while maintaining balance, and as shown in FIG. 7, when the first screen 13 is wound, the pair of torque in opposite directions is decreased while maintaining balance.
  • This operation structure uses a pair of torque T1 and T2 that finely keep balance while being increased or decreased in the opposite directions without a cord, so the operation structure is very simple and can be precisely operated. Further, the balance can be broken by a minimum external force (simply touching the screen or the weight), so the operation structure can be very conveniently operated, and when the external force is removed, the balance is immediately recovered, so the changed length of the first screen 13 can be easily maintained.
  • the first blind module 10 can be very conveniently operated by the operation structure including the first torsion spring 121.
  • the operation structure, as described above, can be applied in the same way to any one of a plurality of blind modules included in the extensible blind apparatus such as the second blind module including the second torsion spring. It is possible to freely and conveniently adjust the amount of blocking light by combining the blind modules. Further, it is also possible to effectively apply the extensible blind apparatus to windows having various sizes, shapes, and dimensions, as described above, by changing the positions of the blind modules. The inter-movement of the first blind module and the second blind module is described in more detail hereafter.
  • FIG. 8 is a bottom view showing movement of the first blind module and the second blind module of the extensible blind apparatus of FIG. 1.
  • the weights and screens of the blind modules are not shown in FIG. 8 to more clearly show the movement.
  • the extensible blind apparatus 1 can be stretched and contracted in the extension direction of the first bar 12 by moving the first blind module 10 and the second blind module 20. That is, the entire width of the extensible blind apparatus 1 can be increased or decreased not in the vertical direction in which the screens are operated by the operation structure described above, but in the lateral direction in which the bars extend. This is because the first blind module 10 and the second blind module 20 can slide in the longitudinal direction of the first bar 12, and it is possible to adjust the entire length by increasing the overlapping portion between the blind modules, as in (a) of FIG. 8, or decreasing the overlaping portion between the blind modules, as in (b) of FIG. 8, to correspond to the width of windows. Accordingly, it is possible to apply the extensible blind apparatus 1 to windows having various dimensions.
  • the extensible blind apparatus 1 even though the rail members are fixed, the first blind module 10 and the second blind module 20 can be moved by sliding, so if necessary, the blind modules can be switched and moved in corresponding directions, so various effects such as changing the blocking area can be achieved. Further, even if it is required to move the extensible blind apparatus 1 to another window having a different size or shape, the extensible blind apparatus 1 can be very easily applied by switching the first blind module 10 and the second blind module 20. Even though the extensible blind apparatus 1 is applied after the width is increased or decreased, the first screen and the second screen can be wound or unwound as described above, so it is possible to more freely adjust the blocking or transmitting area of the entire window.
