[0003]

[Problems to be solved by the device]

 However, the width of the sun visor body is narrow because it is installed so that it does not interfere with the inner mirrors on the driver's side and the passenger's side, respectively. Even if they are stretched along the lines, there is a gap between them, so the light-shielding area must be reduced. Therefore, it is the actual situation that the above-mentioned sun visor device cannot obtain sufficient light shielding performance.

Therefore, a technical problem to be solved by the present invention is to improve the light-shielding property of a sun visor device of a type that shields sunlight by stretching a light-shielding film along the front window.

[0005]

[Means for Solving the Problems]

 In order to solve the above technical problems, the vehicle sun visor device according to the present invention is configured as follows. That is, a fulcrum shaft that extends at a right angle to the front window at a position outside the vehicle body on either the left or right side of the sun visor body provided at the front end of the ceiling surface in the vehicle, and a length corresponding to the width of the sun visor body. Housing formed in a cylindrical shape and rotatably held on a fulcrum shaft, a winding mechanism that winds the light-shielding film so that it can be pulled out into the housing, and a housing at the storage position along the sun visor body and the sun visor body. On the other hand, a positioning means which is set to a position lower than the right angle, a first engaging means provided at the tip of the light-shielding film, and an inner surface of the front pillar located on the opposite side of the one visor body. And a second engaging means for engaging with the first engaging means of the light shielding film pulled out from the cylindrical housing moved to the use position.

[0006]

[Action / effect]

 In the above structure, the housing is set to the use position by the positioning means, the light-shielding film is pulled out from the housing, and the first engaging means at the tip end thereof is engaged with the second engaging means provided on the front pillar. It is possible to cover the front windshield. Since the housing is formed to have a length corresponding to the width of the sun visor body, if the width of the light-shielding film is almost aligned with the housing, the light-shielding film covers the entire front surface of the front window except for the lower end.

On the other hand, when removing the light shielding film from the front window, the first engaging means is disengaged from the second engaging means, the light shielding film is wound into the housing by the winding mechanism, and the housing is further moved by the positioning means. Position it in the storage position along the sun visor body. By doing so, it is possible to remove the cover of the front window with the light shielding film.

When the light-shielding film is stretched on the front window, there is a slight gap at the lower end of the front window, but since the upper surface of the dashboard extends from the lower end of the front window toward the inside of the room. , Almost no sunlight goes into the room. Therefore, when the vehicle is left for a long time during the daytime in summer, the amount of light entering the room can be greatly reduced to prevent the room from becoming hot.

【Example】

 An automobile sun visor device according to an embodiment of the present invention shown in FIGS. 1 to 5 will be described below.

FIG. 1 is an external view showing a portion of a front window side of an interior of an automobile to which the sun visor device is attached in a housed state of the sun visor device, and FIG. 2 is an external view shown in a used state of the sun visor device. .. As shown in the figure, this sun visor device 1 is one in which a light-shielding film 5 is housed in a housing 4 in which a fulcrum shaft 3 provided at a position outside the vehicle body of a sun visor body 2 on the driver's seat side is rotatably supported. The light-shielding film 5 is pulled out with the housing 4 lowered as shown in FIG. 2, and the first hook (first engaging means) 6 provided at the tip thereof is provided on the front pillar 7 on the passenger side. By hooking on the second hook (second engaging means) 8, sunlight is blocked from entering the room.

Next, details of the sun visor device will be described. The sun visor body 2 can be positioned at a position along the inner surface of the front window 9 and at a position along the ceiling surface 10 as in the case of a conventional general sun visor. The fulcrum shaft 3 is provided at the lower end portion on the right side of the sun visor body 2 in a state where the sun visor body 2 is along the inner surface of the front window 9 and is substantially perpendicular to the front window 9. Has been.

The housing 4 is formed in an elongated rectangular tube shape having a length corresponding to the width of the sun visor body 2 so that when the housing 4 is combined with the sun visor body 2, it becomes a normal sun visor form. Although not shown in detail, has a mounting portion 4a in which a recessed portion that rotatably fits with the fulcrum shaft 3 is formed. Further, the housing 4 has a slit 4b for pulling out the light shielding film 5 housed therein along the longitudinal direction.

A winding mechanism 11 shown in an exploded perspective view in FIG. 3 is provided inside the housing 4 in order to wind and store the light shielding film 5. This mechanism comprises a tubular member 12 having one side of the light-shielding film 5 fixed, shafts 13 and 14 that rotatably hold the tubular member 12, and a holder 15 that holds the shafts 13 and 14 non-rotatably. The cylindrical member 12 is composed of a spring 16 provided so as to be always at a fixed position with respect to the shafts 13 and 14, and the holder 15 is fixed in the housing 4. One end of each of the shafts 13 and 14 is crushed to form a fixed portion 13a and 14a, and the shafts 13 and 14 are inserted into the square holes 15c and 15d formed in the holding portions 15a and 15b of the holder 15, respectively. The shaft 14 is rotatably inserted into the right end of the tubular member 12, and the shaft 13 is attached to the tubular member 12 via a sleeve 17 rotatable with respect to the shaft 13. Several protrusions 17a are formed on the outer peripheral surface of the sleeve 17, and a notch 12a into which the protrusion 17a is fitted is formed at the left end of the tubular member 12. The spring 16 has its right end fixed to a bifurcated fixing portion 13b formed on the end of the shaft 13, and its left end fixed to a sleeve 17. Therefore, when the tubular member 12 rotates with respect to the shafts 13 and 14 in the state where this mechanism is assembled, the spring 16 is twisted, and a force for returning the tubular member 12 to the original position is generated.

On the other hand, the housing 4 is set in a storage position along the sun visor body 2 as shown in FIG. 1 and a use position in which the housing 4 is lowered substantially at right angles to the sun visor body 2 as shown in FIG. It has a positioning means for As a positioning means at the use position, a suction cup 18 is provided on the surface on the side of the front window 9, and as a positioning means at the storage position, a lock mechanism 19 shown in FIGS. 4 and 5 is provided. There is.

The housing 4 has a claw 4c at the end opposite to the mounting portion 4a, and the sun visor body 2 has a hole 2a in the end wall 2b for receiving the claw 4c when the housing 4 is in the storage position. is doing. On the inner wall 2c of the sun visor body 2, projecting pieces 2d, 2e, 2f for slidably holding the convex lock piece 20 are formed at diagonally upper positions of the hole 2a. A recess 20b is formed on the back surface of the lock piece 20, and a spring 21 is accommodated between the left end surface 20c of the lock piece 20 and the protruding piece 2f in a state of being bent more than its free length. Therefore, the lock piece 20 is biased to the left in the figure, and the projection piece 20a provided at the lower end of the left end surface 20c covers the hole 2a from the right side by about half. On the other hand, the lock piece 20 has a hole 20d in a portion protruding upward. The front wall 2g of the sun visor body 2 (illustrated separately from the body) has an elongated hole 2h at a position corresponding to the hole 20d of the lock piece 20, and the lock piece 20 is inserted from the front side through the elongated hole 2h. A pin 22a provided upright on the back surface of the slide knob 22 is inserted into the hole 20d. A storage recess 2i for the slide knob 22 is formed in the front wall 2g so that the surface of the slide knob 22 is substantially aligned with the surface of the front wall 2g.

According to the lock mechanism 19 configured as described above, when the pawl 4c is pushed into the hole 2a of the sun visor body 2, the slope 4d of the pawl 4c once moves the lock piece 20 to the right, and the slope 4d is further moved. When the lock piece 20 returns to the original position when the projecting piece 20a is passed over, the housing 4 can be held in the storage position. On the other hand, when lowering the housing 4 to the use position, the slide knob 22 may be moved to the right to separate the protruding piece 20a of the lock piece 20 from the claw 4c. Then, if the suction cup 18 is pressed against the front window with the housing 4 lowered, the housing 4 can be held in the use position.

When the housing 4 is positioned in the use position in this way, the light-shielding film 5 is pulled out from the housing 4 and the first hook 6 at the tip thereof is hooked on the second hook 8 of the front pillar 7, It can be stretched along the front window 9. Since the housing 4 is formed to have a length corresponding to the width of the sun visor body 2 and the width of the light-shielding film 5 is almost the same as that of the housing 4, the light-shielding film 5 covers almost the entire surface thereof except the lower end portion of the front window 9. cover. The upper end of the front window 9 is almost closed by the sun visor body 2, the inner mirror 24, and the sun visor 23 on the passenger side. In addition, although there is a slight gap at the lower end of the front window 9, the upper surface of the dashboard 25 extends from the lower end of the front window 9 toward the inside of the room, so it is difficult for sunlight to directly enter the room. It can be prevented. Therefore, it is possible to significantly reduce the amount of light entering the room and prevent the room from becoming hot.

On the other hand, when the first hook 6 is removed from the second hook 8, the light shielding film 5 is wound into the housing 4 by the winding mechanism 11, so that the housing 4 is moved to the storage position by the lock mechanism 19 as described above. Positioning the sun visor body 2 along with the sun visor 23 on the passenger side to the ceiling surface allows the front windshield 5 to be uncovered, which does not hinder driving.

The present invention is not limited to the above embodiment, but can be implemented in various other modes. For example, as the positioning means of the housing 4, a spring or a ball is used to position the retractable door mirror at the operating position and the storage position, instead of the locking mechanism and the suction cup as shown. A mechanism such as a detent mechanism may be provided around the fulcrum shaft. Further, instead of the hooks provided as the first and second locking means, for example, sheet fasteners may be used.
