Description

  The present invention relates to a cartridge type automobile sunshade device that prevents the interior of an automobile from being heated by sunlight.

  If you leave the car in the summer, etc., when you come back, the inside of the car is heated by sunlight and becomes very hot, and when you enter the car, you feel very uncomfortable. For this reason, the air conditioner is activated in a hurry, but it takes a considerable amount of time to cool down the interior of the vehicle and wastes energy. In addition, when leaving the interior of the vehicle unattended, the interior of the vehicle is indiscriminately viewed directly (at least through the windshield), which causes safety concerns and privacy issues.

  For this reason, the windshield part is covered with a sunshade device when the automobile is away in summer or the like. This sunshade device is a device in which a bellows-like light-shielding screen is spread and stood on an instrument panel, but each time it has to be widened or folded, it is troublesome. In addition, a separate storage location is required.

For this reason, a retractable sunshade device as disclosed in Patent Document 1 has been proposed. However, in this case, a mandrel previously molded in accordance with the curvature of the windshield on the light shielding screen is stretched at an appropriate interval, so that the structure becomes complicated and the price increases and the weight also increases. In addition, since the curvature of the windshield is different for each automobile, the cored bar and the shading screen must be manufactured for each vehicle type. Furthermore, since the light-shielding screen is folded and accommodated in a pocket formed on the instrument panel, it is not always the same as the original folding when being accommodated.
Japanese Patent Laid-Open No. 10-175432

  The problem to be solved by the present invention is to realize a sunshade device that has a high sunshade effect, is safe, reliable, and inexpensive, and that it can cope with a slight difference in size of the instrument panel with the same one. It is a versatile one.

  According to the present invention, a pocket having a shape substantially conforming to the curvature of the windshield is formed in the upper surface of the instrument panel at the rear of the defroster outlet, and the pockets are formed in the end members at both ends. A flexible rod that can be rotated along the shape of the core rod, which is fixed along the core rod, and is fitted to the core rod, and a flexible light-shielding screen is wound around the outer periphery of the core rod so that it can be unwound. A cartridge consisting of a drum, and a flexible frame that accommodates the drum and connects the front and rear of the end members at both ends to bend into the shape of a pocket. The present invention provides an automobile sunshade device characterized by being covered with a cover.

  By the above means, since the light shielding screen accommodated in the cartridge remains as it is along the curve of the windshield, it is possible to make it close to the windshield without requiring a metal core. Further, since the light shielding screen is wound around the drum, unwinding and winding are reliable. Furthermore, since the shading screen is a cartridge type, it is easy and easy to install and remove.

  FIG. 1 is a front view of a front seat of an automobile showing an embodiment of the present invention, and FIG. 2 is a sectional view of a windshield portion of the automobile. The sunshade device according to the present invention is a defroster blower for an instrument panel 1 of an automobile. A pocket 4 having a shape substantially conforming to the curvature of the windshield 3 is formed on the upper surface of the position behind the exit 2 (in front of the airbag installed on the passenger seat side, in front of it) as close to the windshield 3 as possible. Then, a cartridge 6 containing a light shielding screen 5 is accommodated in the pocket 4, and the upper part thereof is covered with a cover 7 that can be opened and closed.

  3 is a longitudinal sectional view of the cartridge 6, and FIG. 4 is a transverse sectional view. However, the cartridge 6 unwinds and winds the core rod 9 supported at both ends by the square end members 8 and the light shielding screen 5. The drum 10 is wound around as possible, and the frame 11 connects the end members 8. The end member 8 is fitted into both ends of the pocket 4 and holds the core rod 9 in a non-rotatable manner. In this case, since the pocket 4 is formed in a shape substantially along the curve of the windshield 3, the core rod 9 is also made of a flexible material such as a resin or a metal rod so as to follow this shape.

  Similarly, the drum 10 is made of a flexible material such as resin or rubber, and is fitted to the outer periphery of the core rod 9 along the curved shape. The drum 10 rotates with the unwinding and winding of the light-shielding screen 5, but its flexibility and the degree of bending are not so large (the length of 1400 mm and the amount of bending protrusion is about 130 mm). Rotating without breaking the curved shape, that is, rotating around the core rod 9. In this case, a certain amount of space is provided between the core rod 9 and the drum 10. One end is fixed to the core rod 9 and the other end is fixed to the drum 10 and wound around the core rod 9. A coil spring 12 is accommodated. The coil spring 12 constitutes a winding mechanism 13 and is wound in a direction in which the drum 10 (light shielding screen 5) is always wound.

  The frame 11 is a plate-like member that connects the front and rear of the end member 8 at substantially the same height as this, and is also made of a flexible material such as resin. FIG. 5 is a plan view of the cartridge 6. Even when the frame 11 remains straight, when the cartridge 6 is accommodated in the pocket 4, the core rod 9, the drum 10, and the frame 11 are curved so as to follow the shape of the pocket. In this respect, it is possible to freely cope with the curvature of the windshield 3, and it is not necessary to manufacture according to the vehicle type. The light shielding screen 5 wound around the drum 10 is accommodated between the frames 11.

  The light-shielding screen 5 is composed of a thin fabric (including non-woven fabric), paper, resin, etc. that blocks sunlight, and one end in the length direction is fixed to the drum 10 and wound around the drum 10, and the other end is It is what is peeping from the frame 11. Therefore, when the other end of the light-shielding screen 5 is pulled up, the drum 10 rotates to enable unwinding, and when the lifting force is released, the drum 10 is reversely rotated by the winding mechanism 13 and the light-shielding screen 5 is wound. Taken. The light-shielding screen 5 may be a solid one, but may have a suitable design or pattern.

  The other end (unwinding end) of the light shielding screen 5 is provided with a locking bar 14 exceeding its width, and one or a plurality of mounting holes 15 are formed at the center thereof. Therefore, even if the light shielding screen 5 is urged in the winding direction by the winding mechanism 13, the locking bar 14 does not hang on the end member 8 and fall into the frame 11.

  The cover 7 is made of the same material as the instrument panel 1 and is formed so that the front can be opened and closed on the open side by a hinge 16 or the like. The cover 7 covers the pocket 4, but does not need to have the same shape as the pocket 4 formed according to the curvature of the windshield 3. FIG. 6 is a plan view of the cover 7, but the point is that it only needs to cover the upper surface of the pocket 4. In this respect, the rear surface of the rotating side to which the hinge 16 is attached may be straight. (It may be a curved surface.) When the cover 7 is closed, its height is flush with the surface of the instrument panel 1.

  The cartridge 6 as described above is a unit that constitutes the sunshade device, and the assembly of the sunshade device is completed only by housing this in the pocket 4. In this example, this accommodation is performed by the one-touch engagement / disengagement mechanism 17. That is, a lever 18 that has an engagement hole 18a on the outer side surface and an inclined surface 18b that protrudes outward toward the lower side is provided on the outer side surface of the end member 8, and the pocket 4 A cam 20 that can be fitted into the engagement hole 18a is provided on the opposite end surface of the inner surface (the lining material 19 such as a metal sash may be fitted on the inner surface).

  At this time, the protrusion length of the cam 20 can be adjusted by the adjusting mechanism 21. In this respect, even if the length of the pocket 4 is slightly different, it can be handled. This means that the range that can be accommodated by one cartridge 6 is widened even if the vehicle type is slightly different, combined with the fact that the cartridge 6 can freely cope with the curvature of the windshield 3, and it is necessary to manufacture for each vehicle type. There is an advantage that there is no.

  When both ends of the cartridge 6 are held by hand and lowered into the pocket 4 from above, the cam 20 hits the inclined surface 18b of the lever 18, and the lever 18 is moved closer to the end member 8 side as the cartridge 6 is lowered. It is inserted into the engagement hole 18a. Then, the lever 18 returns to its original shape by its elastic force, and the engagement hole 18 a and the cam 20 are completely fitted together, and the cartridge 6 is fixed to the pocket 4. When the cartridge 6 is removed from the pocket 4, it can be pulled out as it is if the lever 18 is moved toward the end member 8 to disengage the cam 20. Note that the engagement / disengagement mechanism 17 is not limited to the above-described one, and various other mechanisms can be considered.

  Since this operation can be easily performed on the user side, when the sunshade is not required in winter or the like, if the cartridge 6 is removed, this space can be used for an accessory case. Moreover, if several types of light-shielding screens 5 with different patterns are prepared, it is possible to change the mood.

  Next, the use of the sunshade device will be described. When the sunshade is required, first, the cover 7 is opened, the upper end portion of the light shielding screen 5 is held up, and the locking rod 14 and the hole 15 are moved upward. 3 Hook on the hook 22 provided above. At this time, since the drum 10 around which the light shielding screen 5 is wound rotates while maintaining the curved posture, the drawn light shielding screen 5 is also curved. And when the upper end is hooked on the hook 22, this curved state is maintained by at least the center portion being hooked.

  In addition to the above, there are various types of locking of the upper end of the light shielding screen 5. FIG. 7 is a front view of a portion of the windshield 3 showing another example. When a presser plate 23 that rotates around the upper end is provided on the panel above the windshield 3 and the shading screen 5 is pulled up, this presser is shown. The plate 23 is rotated downward to press the upper end of the light shielding screen 5. Further, a clip (not shown) or the like may be hung on the panel portion, and the shading screen 5 may be hung by this. In some cases, a double-sided tape (not shown) is provided near the upper end of the shading screen 5. ) May be stopped. In short, anything may be used as long as the upper end of the light shielding screen 5 can be fixed along the curvature of the windshield 3.

  As described above, the light shielding screen 5 follows the curvature of the windshield 3 and is kept as close as possible to this, so that the light shielding effect and the see-through preventing effect are high. This sunshade device is effective not only for light shielding in summer and the like, but also for removing fog on the windshield 3 in winter and the like. For this purpose, it is suitable to provide the light shielding screen 5 as close as possible to the windshield 3 behind the defroster outlet 2. In this way, since the defroster air flows in a narrow space at a high speed, it can be removed in a short time even if the air is not warm.

  On the other hand, when the light-shielding screen 5 is lowered, an operation for releasing the engagement such as the disengagement of the hook 22 may be performed and the lowering may be performed downward. At this time, since the winding mechanism 13 is incorporated in the drum 10, the operation is easy and fast. When the light shielding screen 5 is accommodated in the cartridge 6, the cover 7 is closed. At this time, since the cover 7 and the upper surface of the instrument panel 1 are flush with each other, the view is not blocked.

  Although the vehicle does not travel with the light-shielding screen 5 raised, for safety, the cover 7 is closed by a micro switch or the like, and an alarm sounds if the shift lever is moved to a position other than P without detecting this. If so, safety is ensured. In addition, the above sunshade device can be applied not only to the windshield but also to other surfaces such as a rear glass and a side glass.

  In the above description, the light shielding screen 5 is raised and lowered manually, but this may be automated. There are various methods for automation. For example, a drum driven by a motor on the ceiling or the like is arranged, and a string wound around the drum is taken down and hooked on the light shielding screen 5 to be lifted. Further, the cover 7 may be opened and closed by a motor, an electric cylinder or the like.
