Description

[Technical field]

[0001] The present invention relates to a roll-up sun visor that is attached to the vicinity of the windshield of an automobile. [Background technology]

[0002] Sun visors are provided to block sunlight entering the interior of automobiles while driving or parking. A typical automobile sun visor has a structure in which a light shielding plate is rotatably supported on a support shaft provided above the front window, and is turned to a light shielding state by rotating downward.

[0003] When driving a car, it is enough if the sun visor can block the minimum amount of sunlight necessary to ensure forward visibility, but when the sun is low in the sky, such as in the morning or evening, conventional sun visors cannot block the sunlight. Thus, conventional sun visors are insufficient because the areas they can block are limited.

[0004] To address such problems, for example, Patent Document 1 describes an extended sun visor that can easily and reliably cover the windshield by pulling out and storing the extended visor, which is stored in a roll in a storage section formed inside the extended sun visor body, freely.

[0005] Furthermore, Patent Document 2 describes a sun visor that has a storage section at the tip of the sun visor that has a circular cross section and an opening, in which a roll-shaped shade is detachably stored, and which is raised and lowered through the opening.

[0006] However, with conventional roll-up sun visors, it can be difficult to finely adjust the position of the sun visor. [Prior art documents] [Patent documents]

BEST MODE FOR CARRYING OUT THEINVENTION

[0017] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Note that the present embodiments described below do not unduly limit the content of the present invention described in the claims, and all of the configurations described in the present embodiments are not necessarily essential as the means for solving the problems of the present invention.

[0018] Fig. 1 is an internal perspective view showing an outline of a roll-type sun visor according to one embodiment of the present invention, and Fig. 2 is a front view showing a screen part of the roll-type sun visor according to one embodiment of the present invention. One aspect of the present invention is a roll-type sun visor 10 that is attached to the vicinity of the windshield of an automobile and is equipped with a roll-type screen 20 and a main body 11 that stores the screen 20 and can adjust the fixed position of the screen 20, the main body 11 has a winding coil 13 for rewinding the screen 20 and stoppers 12, 14 for fixing the pulled-out screen 20 at a predetermined position, the screen 20 is provided with a position adjustment part 21 for adjusting the pull-out distance and a light-shielding layer forming part 22 that forms a light-shielding layer by a frame 24 inserted inside, and a plurality of grooves 23 that can engage with the stoppers 12, 14 are provided on the side of the position adjustment part 21.

[0019] The main body 11 is the core of the roll-type sun visor 10, and houses the roll-type screen 20 inside. The screen 20 is wound around a central winding shaft, for example, and the winding shaft is connected to a winding coil 13, so that the roll-type screen 20 can be unwound.

[0020] Furthermore, the main body 11 is provided with stoppers 12, 14 at both the left and right ends (or only on one side) so that the user can stop and fix the pulled-out screen 20 at an appropriate position. The stoppers 12, 14 are configured to be engageable with the grooves 23 of the screen 20, and the screen 20 can be adjusted to a predetermined length by the stoppers 12, 14 engaging with the grooves 23. In one embodiment of the present invention, as an example, a dial 16 may be provided at one end of the main body 11, and the screen 20 may be unwound (lowered) or wound up (raised) by rotating it, and the stoppers 12, 14 may be fixed (stopped at a predetermined position) or released (winding up the roll by the winding coil 13) with a button or the like.

[0021] In one embodiment of the present invention, a mounting member 30 is provided on the main body 11, and the roll-up sun visor 10 according to the present invention is installed near the windshield of the automobile via the mounting member 30. Alternatively, the mounting member 30 may be a conventional sun visor for automobiles with the light shielding plate removed. As an example, the mounting member 30 may be formed by providing a cylindrical receiving hole in the center of the main body 11 and the roll shaft, into which the shaft can be inserted, and inserting the mounting member 30 into the receiving hole and fixing it using a fastening member 15 such as a tightening ring. In this way, the main body 11 of the roll-type sun visor 10 can be slid laterally (direction D in FIG. 1) to adjust the position.

[0022] Next, the configuration of the screen 20 of the roll-type sun visor 10 according to the present invention will be described. As shown in Fig. 2, the screen 20 of the roll-type sun visor 10 according to one embodiment of the present invention is provided with a position adjustment section 21 for adjusting the pull-out distance and a light-shielding layer forming section 22 for forming a light-shielding layer. The screen 20 is formed of a material such as PTFE (polytetrafluoroethylene).

[0023] The position adjustment unit 21 is provided on the base side (roll shaft side) of the roll-shaped screen and adjusts the pull-out distance. The length h of the position adjustment unit 21 is, for example, about 100 to 500 mm. The position adjustment unit 21 does not need to be pulled out when the sun is above and the same usage position as a normal sun visor is sufficient, but when the sun is low in the sun such as in the morning or evening, the position adjustment unit 21 can be pulled out to lower the shading position of the sun visor. In this way, in the roll-type sun visor 10 according to the present invention, the shading position can be easily set by the degree to which the position adjustment unit 21 is pulled out.

[0024] The light-shielding layer forming portion 22 is a portion of the roll-type sun visor 10 that provides light-shielding and heat-insulating effects against the sun. As an example, the light-shielding layer forming portion 22 maintains its shape by inserting a metal frame 24 inside. The light-shielding layer forming portion 22 may be formed by, for example, inflating the light-shielding layer forming portion 22 of the screen 20 by inserting air inside to form an air layer. As an example, the frame 24 may be formed in a comb shape as shown in FIG. 2. In this way, the strength of the light-shielding layer forming portion 22 can be increased. The light-shielding layer forming portion 22 may be made to be about the same size as the light-shielding portion of a general sun visor, and is preferably made to be an embodiment that can provide excellent light-shielding and heat-insulating effects.

[0025] In the present invention, as shown in Fig. 2, a plurality of grooves 23 capable of engaging with the stoppers 12, 14 are provided on the side surface of the position adjustment part 21. Here, Fig. 3 is a perspective view showing an engagement state between the stoppers and the grooves in a roll-type sun visor according to one embodiment of the present invention. In one aspect of the present invention, as shown in Fig. 3, the length of the screen 20 of the roll-type sun visor 10 can be adjusted by the stoppers 12 provided on the inner surface of the end part of the main body 11 engaging with the grooves 23 provided in the position adjustment part 21 of the roll-type sun visor 10.

[0026] The stopper 12 may be a hook-shaped metal member as shown in FIG. 3, and fixes the screen 20 at a predetermined position in a state where it engages with the groove of the groove 23. The stoppers 12, 14 and the groove 23 may be provided on both ends of the roll-type sun visor 10, or may be provided only on one end. A plurality of the grooves 23 are provided on the side of the position adjustment part 21, for example, at intervals of 10 to 30 mm. The grooves 23 and the vicinity of the grooves may be formed of a wear-resistant material such as stainless steel so that they do not wear out after multiple uses. As an example, the stoppers 12, 14 may be provided with a button or the like on the main body, and the stoppers 12, 14 may be moved toward and away from the grooves 23 in conjunction with each other to fix and release the screen 20.

[0027] Fig. 4 is a plan view of the vicinity of the driver's seat of an automobile for explaining an installation mode of a roll-up sun visor according to one embodiment of the present invention. In one aspect of the present invention, as shown in Fig. 4, a mounting member 30 for mounting the main body 11 to the automobile 1 may include a moving mechanism for rotating the main body 11 from the vicinity of the windshield 2 to the vicinity of the side window 3 of the automobile 1.

[0028] Such a moving mechanism may be such that the mounting member 30 has a rotation mechanism for rotating the main body and a slide mechanism for adjusting the horizontal position of the main body. The rotation mechanism may be configured to have a vertically downward rotation axis from the ceiling of the automobile 1 by appropriately installing a joint structure, so that the rotation mechanism can be configured to rotate in the direction R in FIG. 4. The slide mechanism may be configured, for example, to temporarily loosen the fastening member 15 and slide the mounting member 30 in the horizontal direction (horizontal direction D, see FIG. 1), and then tighten the fastening member 15 again, or a slide mechanism may be installed around the receiving hole of the mounting member 30. Such an operation may be performed manually by the driver 5 sitting in the driver's seat 4, for example, or may be automatically operated by operating a button or the like. In this way, the sun visor can be rotated toward the side glass to adjust the position, so that sunlight from the side can also be prevented.

[0029] As described above, according to the present invention, the position of the sun visor can be easily adjusted, and excellent light blocking and heat insulating effects can be obtained.
