DESCRIPTION OF SPECIFIC EMBODIMENTS

[0036] Hereinafter, a bidirectional window screen for a vehicle according to the present disclosure is described in detail with reference to the accompanying drawings.

[0037] As shown in at least FIGS. 3-6, a bidirectional window screen for a vehicle according to the present disclosure includes a guide 30 having upper and lower ends installed on a frame, and a roll screen 41 wound around the inside of the guide 30 to be withdrawn from the guide 30 or stored in the guide 30. The guide 30 is slidable in a longitudinal direction of the vehicle.

[0038] The guide 30 is installed to have the upper and lower ends connected to the frame on which a window is installed. The guide 30 is formed in a height direction of the vehicle and formed to connect the upper and lower ends of the frame.

[0039] The roll screen 41 for blocking sunlight is accommodated in the guide 30, and withdrawn and deployed if necessary, thereby blocking the light.

[0040] The guide 30 is installed to be slidable in the longitudinal direction of the vehicle.

[0041] To be slidable, the guide 30 has an upper rail 21 and a lower rail 22 configured to guide the sliding of the guide 30 installed on the upper and lower ends of the frame, respectively.

[0042] Referring to FIG. 9, the inside of the upper rail 21 is formed in a hollow shape, and the upper rail 21 is formed with a slit 21a having an opened lower end. The upper rail 21 and the lower rail 22 have the same forms and are installed in a vertically inverted form (i.e., symmetrical with respect to each other). Therefore, the inside of the lower rail 22 is also formed in a hollow shape in the longitudinal direction of the vehicle and formed with a slit 22a having an opened upper end.

[0043] Moving blocks 36 sliding along the upper rail 21 and the lower rail 22 are installed on the upper rail 21 and the lower rail 22. The moving blocks 36 are fixed to the upper and lower ends of the guide 30, respectively, allowing the guide 30 to slide on the upper rail 21 and the lower rail 22.

[0044] The moving blocks 36 have a main body accommodated in the upper rail 21 and the lower rail 22, i.e., in the slits 21a, 22a. Additional moving blocks 36 may also be accommodated in the slit 21a or the slit 22a.

[0045] The moving blocks 36 are fastened to the upper and lower ends of the guide 30, so that the guide 30 is slidable on the window.

[0046] The moving blocks 36 are formed with a bolt part 36a to pass through the slits 21a, 22a. The bolt parts 36a of respective moving blocks 36 are fastened to corresponding upper and lower ends of the guide 30. In this way, the guide 30 can slide with the moving blocks 36. As shown in FIG. 10, the upper and lower ends of the guide 30 are formed with a fixing groove 33 so that the bolt part 36a can pass through it. A fixing nut 37 is fastened to the bolt part 36a passing through the fixing groove 33 in a screw-coupling manner, and therefore, the moving blocks 36 are installed on the upper and lower ends of the guide 30, respectively. As described above, since the moving blocks 36 are fastened to the upper and lower ends of the guide 30, respectively, the guide 30 becomes slidable in the longitudinal direction of the vehicle.

[0047] As shown in FIG. 7, a roll screen unit 40, including the roll screen 41, a shaft 42, and a spring 43, is withdrawn and deployed when accommodated in the guide 30, thereby covering the window.

[0048] To this end, as shown in FIG. 6, the roll screen 41 is accommodated when wound around the inside of a roll screen accommodation part 31 formed on the guide 30. The roll screen 41 is accommodated in the roll screen accommodation part 31 when wound to be easily deployed when used, while having a minimum volume when not used.

[0049] The roll screen accommodation part 31 is formed in a vertical direction of the vehicle.

[0050] Referring to FIG. 8, one side of the roll screen accommodation part 31 is formed with a withdrawal slit 32 through which the roll screen 41 is withdrawn in the longitudinal direction of the vehicle. The roll screen 41 accommodated in the roll screen accommodation part 31 is withdrawn to the outside of the guide 30 through the withdrawal slit 32 while being sequentially released. Of course, when not using the roll screen 41, the roll screen 41 is stored in the roll screen accommodation part 31 through the withdrawal slit 32.

[0051] The roll screen 41 has a structure of a rollback screen type, and therefore, is automatically wound when stored. In other words, referring back to FIG. 7, the roll screen accommodation part 31 is provided with the rotatable shaft 42 around which the roll screen 41 is wound, and the spring 43 is configured to provide an elastic force in a direction in which the shaft 42 winds the roll screen 41. Therefore, to use the roll screen 41, the passenger withdraws the roll screen 41 at an operation force larger than the elastic force. In addition, to store the roll screen 41, the roll screen 41 is automatically wound by the elastic force of the spring 43 if the passenger releases the roll screen 41.

[0052] As shown in FIGS. 3 and 5-7, an end of the roll screen 41 is formed with a shade bar 44 configured to suppress the end of the roll screen 41 from entering the roll screen accommodation part 31 through the withdrawal slit 32. Thus, the end of the roll screen 41 maintains a constant form when the roll screen 41 is used. The shade bar 44 is formed at a thickness larger than a width of the withdrawal slit 32. Therefore, the end of the roll screen 41 maintains a state of being locked to the withdrawal slit 32 when the roll screen 41 is not used and may be easily withdrawn when the roll screen 41 is used.

[0053] In addition, the shade bar 44 is formed with a knob 44a configured to allow the passenger to perform an operation of grabbing the shade bar 44 and withdrawing the roll screen 41. The knob 44a may be a flange or any other type of projection or protuberance extending outward from the shade bar 44.

[0054] In addition, the shade bar 44 can be coupled to a pillar 12 or a member of the vehicle, which can be coupled to the shade bar 44 of another roll screen 41, such that both shade bars 44 may be withdrawn to face each other to maintain the state where the roll screens 41 are withdrawn. For example, as shown in FIG. 11, an end of the knob 44a may be formed with a hook 44b, and the pillar 12 may be formed with an accommodation groove 12a accommodating the hook 44b so that the hook 44b is locked to the accommodation groove 12a, thereby maintaining the state where the roll screens 41 are deployed.

[0055] Alternatively, the respective shade bars 44 of the respective roll screens 41 that are withdrawn to face each other may each be formed with the hooks fastened to each other, respectively, or each may be formed with the hook and the accommodation groove, respectively, to be locked to each other when the roll screens 41 are deployed, thereby maintaining the state where the roll screens 41 are deployed.

[0056] Referring to FIG. 5, the guide 30, on the indoor side of the vehicle, may be coupled with a cover 35 configured to cover one side of the guide 30. In other words, the cover 35 is configured to cover the guide 30 on the indoor side of the vehicle side of the guide 30 (i.e., the side of the guide 30 facing the inside of the vehicle).

[0057] The operation of the bidirectional window screen for the vehicle according to the present disclosure having the above configuration is described as follows.

[0058] According to the present disclosure, since the guide 30 is installed to be slidable in the longitudinal direction of the vehicle, the guide 30 is adjusted to fit a location of a seat 11 in the vehicle such as a bus, so that the passenger withdraws and uses the roll screen 41 when necessary.

[0059] The guide 30 may be configured to be located on a boundary portion of each seat 11. Since the roll screen 41 can be independently withdrawn to the front and rear of the vehicle, respectively, from the guide 30, a passenger on a seat 11 in front of the guide 30 and a passenger on a seat 11 in the rear of (i.e., behind) the guide 30 can freely deploy and use the roll screen 41 when the guide 30 is located on the boundary portion of each seat.

[0060] In FIG. 11, the guide 30 is located adjacent to a backrest of the No. {circle around (3)} seat 11. Since the roll screens 41 are independently withdrawn to the front and rear of the vehicle, respectively, from the guide 30, even if a passenger on the No. {circle around (3)} seat withdraws and uses the roll screen 41, it does not affect passengers on the No. {circle around (2)} and No. {circle around (4)} seats located to the front and rear thereof.

[0061] In such a manner, the passengers on the No. {circle around (1)} to {circle around (5)} seats can freely withdraw and use the roll screens 41 while not affecting each other.

[0062] In addition, since the guide 30 can be moved in the longitudinal direction of the vehicle, the roll screen 41 can be withdrawn, deployed, and used at the optimal location by moving forward or backward the guide 30 from the current location in an incident direction of sunlight.

[0063] In addition, if the interval between the seats 11 is changed, the guide 30 can be moved in response thereto so that the roll screen 41 can be deployed at the optimal location.
