Description

Technical Field

[0001] The present invention relates to a door curtain of a vehicle, and more particularly to a door curtain mechanism of a magnetic force support base for selectively blocking sunlight entering from the windshield of a vehicle door.

Background Art

[0002] Generally, shades for various windows installed in automobiles are implemented in ways such as curtains, blinds, and sheets. In any method, light-shielding property is the most important factor, but in addition to light-shielding property, convenience in installation and use and aesthetic beauty of the appearance are also required. A sunshade mounted on an automobile door in a winding manner is advantageous in terms of convenience and aesthetic beauty. On the other hand, considering simplicity of configuration and cost, a manual winding type is more practical than an electric winding type. On the other hand, the winding type has a disadvantage in that due to structural constraints of being coupled to the inner panel of the door, it cannot completely cover the door window and is partially exposed.

[0003] As prior art documents related to sunshades of vehicles, there are the following Japanese Patent Application Laid-Open No. 2004-42772 (Prior Art Document 1), Korean Registered Patent Publication No. 1568300 (Prior Art Document 2), and the like.

[0004] Prior Art Document 1 seals the upper edge portion of the windshield that opens and closes the window opening of the vehicle with a weather strip, and locks a pull-out sunshade to the hook portion of a mounting member coupled to the weather strip. Thereby, in Prior Art Document 1, since the weather strip does not have a gap due to the mounting member, it is possible to expect an effect of preventing noise and water from entering the room.

[0005] Prior Art Document 2 forms a fixed shaft via fixed blocks on both side surfaces of a roll case, a flexible coupling member couples the fixed blocks to the inner panel, and a support shaft provided with a plurality of clips at the upper end of a sun screen is coupled. Thereby, in Prior Art Document 2, it is possible to expect an effect of easily and simply installing a roll blind and stably pulling out the sun screen.

[0006] However, since the clip presented in the prior art has a structure in which a locking flange is formed at the end, the upper end of the sunshade cannot cover the upper side of the window, and there is a problem that sunlight enters through the gap.

[0017] Hereinafter, the door curtain mechanism of the magnetic force support base according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0018] The present invention proposes a door curtain mechanism supported by magnetic force on a door frame 10. It is targeted at a curtain mechanism installed on a vehicle door frame 10, but is not limited thereto. The door frame 10 supports the glass 15 so as to be movable up and down, and the door curtain mechanism performs a light-shielding function with respect to the glass 15.

[0019] According to the present invention, a curtain means 20 configured by coupling a support bar 23 to the upper end of a sunshade 21 has a structure provided with locking holes 32 on the support bar 23. The curtain means 20 is based on a sunshade 21 having a flexible structure with light-shielding properties. The support bar 23 integrally fixed to the upper end of the sunshade 21 is formed of a rigid structure that supports a load. The locking holes 32 formed in the support bar 23 are structured to be coupled to hooks 41 described later. It is desirable to form the locking holes 32 at two locations, but it is not limited thereto.

[0020] Here, a winder 25 can be accommodated inside the door frame 10, and the lower end of the sunshade 21 can be connected to the winder 25. When shielding light, when the support bar 23 is pulled upward, the sunshade 21 is pulled out from the winder 25. Conversely, when the support bar 23 is released, the sunshade 21 is wound around the winder 25 by an urging force.

[0021] On the other hand, although not shown in the drawings, the winder 25 can adopt a known configuration so as to cause a horizontal movement in addition to the vertical movement of the sunshade 21. The horizontal movement of the sunshade 21 is for varying the light-shielding area corresponding to the shape and size of the glass 15.

[0022] According to the present invention, a locking means 40 configured by coupling a hook 41 formed with an L-shaped cross section to the door frame 10 has a structure that maintains the coupling between the support bar 23 and the hook 41 by magnetic force. The glass 15 is in close contact with the weather strip 12 installed on the door frame 10, and the hook 41 is coupled to the door frame 10 with a certain distance from the glass 15. The hook 41 is provided with an L-shaped cross section without a protruding portion at the lower end, engages with the locking hole 32 of the support bar 23, and supports the sunshade 21.

[0023] According to the detailed configuration of the present invention, the curtain means 20 is characterized in that it is provided so as to maintain a gap of 3 mm or less between the upper end of the support bar 23 and the lower end of the door frame 10.

[0024] Figure 1(a) shows a general hook 41. Based on the L-shaped cross section, a locking flange 41a protrudes from the lower end. In the process of attaching and detaching the support bar 23 to the hook 41, the locking hole 32 has to cross the locking flange 41a as shown by the arrow, so a space is required above the support bar 23, and such a space deteriorates the light shielding property. On the other hand, as shown in Figure 1(b) showing the present invention, according to the hook 41 with an L-shaped cross section from which the locking flange 41a at the lower end is eliminated, the support bar 23 only needs to move linearly as shown by the arrow. Therefore, a minimum space (gap) is formed above the support bar 23, preventing the light shielding property from deteriorating.

[0025] Here, providing a gap of 3 mm or less between the upper end of the support bar 23 and the lower end of the door frame 10 is sufficient to prevent the light shielding property from deteriorating. However, the closer the gap is to 0 mm, the more difficult it is to fit the support bar 23 into the hook 41.

[0026] In the case of Figure 1(a), since the width of the locking hole 32 provided in the support bar 23 is large, there is a high possibility of generating noise when the vehicle is running. However, in the case of Figure 1(b), since the width of the locking hole 32 is reduced in accordance with the thickness of the lower end of the hook 41, the possibility of generating noise is lowered. The symbol 'D' in Figure 1 indicates the upper part of the support bar 23 when going from Figure 1(a) to Figure 1(b). the space on the sideIt means a state where the height is reduced.

[0027] According to the detailed configuration of the present invention, the locking means 40 is characterized in that a magnet 43 on one side and a magnetic body 45 on the other side are provided at positions where they can face each other.

[0028] As shown in FIGS. 1 to 3, the locking means 40 attaches the magnet 43 to the hook 41 and attaches the magnetic body 45 to the support bar 23. However, the magnet 43 and the magnetic body 45 can also be attached in opposite directions. Since the loads of the sunshade 21 and the winder 25 are supported by the lower end of the hook 41, a large magnetic force between the magnet 43 and the magnetic body 45 is not required, and the support bar 23 can be easily attached and detached. The magnetic body 45 is suitable for a metal material from the aspect of durability, but is not limited thereto.

[0029] As a modification of the present invention, the support bar 23 is further characterized by further comprising an extending portion 34 communicating with the locking hole 32 so as to allow horizontal movement of the sunshade 21 engaged with the hook 41.

[0030] Referring to the right detailed view in FIG. 4, it shows a state where the extending portions 34 are provided on both sides of the locking hole 32. As described above, when the sunshade 21 has a structure that allows horizontal movement, the hook 41 enters from the locking hole 32 into the extending portion 34. In order to prevent arbitrary movement of the sunshade 21, the extending portion 34 is slightly narrower than the locking hole 32 or the extending portion 34 is provided with uneven portions 36. The uneven portions 36 can adopt an engagement structure of protrusions and grooves.

[0031] As another modification of the present invention, the magnet 43 is further characterized by further comprising a wrinkled portion 46 or a roller portion 47 so as to reduce the sliding resistance on the surface facing the magnetic body 45.

[0032] In FIG. 4, the left detailed view shows the configurations of the wrinkled portion 46 and the roller portion 47 on a plane. When the user manually or uses the winder 25 to cause the horizontal movement of the sunshade 21, the magnetic body 45 of the support bar 23 first contacts the magnet 43 of the hook 41, reducing the sliding resistance. The wrinkled portion 46 has a shape protruding with a circular or triangular cross-section, and the roller portion 47 has a structure that rotates around a vertical axis.

[0033] Of course, the wrinkled portion 46 or the roller portion 47 can also be formed on the magnetic body 45 instead of being formed on the magnet 43.

[0034] As described above, the invention made by the present inventor has been specifically described by the above embodiments. However, it goes without saying that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof.
