Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sun visor support device installed in a vehicle compartment, and more particularly to a sun visor support device capable of varying a light-shielding range.

[0002]

[Prior art]

 For example, above the front window, various sun visors are installed for the purpose of ensuring the traveling visibility of passengers.

A normal sun visor has a structure in which one end of the sun visor body is supported via an L-shaped rotation shaft so that the sun visor can be rotated vertically and horizontally. Like the auxiliary visor in the double visor, a sun visor that can move up and down between the state of being stored on the ceiling and the state of use located parallel to the windshield is also used.

As shown in FIG. 7 based on Japanese Utility Model Laid-Open No. 3-128512, for example, a sun visor body 1 having a sunshade function is movably supported by a holder 3 fixed to a ceiling 2. The holder 3 includes a rod-shaped support portion 4, and shaft holes 4a are formed in both end surfaces of the support portion 4.

On the other hand, the sun visor body 1 is configured by covering the surface of the core 1 a with the skin material 1 b, and a notch 5 is opened in the center, and the notch 5 has a shaft hole 4 provided in the holder 3. A supporting shaft 6 fitted to a is attached, and the spring force of the spring 7 urges the supporting shaft 6 into the shaft hole 4a of the holder 3 in the insertion direction. The sun visor body 1 is supported so as to be vertically movable by rotatably bearing the support shaft 6.

[0006]

However, in such a vertically movable sun visor, the light shielding range is limited, and it is impossible to change the light shielding range of the sun visor depending on the incident direction of the sun rays. It is not possible to sufficiently achieve the purpose of effectively ensuring the traveling visibility of passengers.

The present invention has been made in view of such circumstances, and is a sun visor support device that can selectively take a storage state on a ceiling surface and a use state on a front window surface, and It is an object of the present invention to provide a sun visor support device that is easy to use because the light-shielding range can be appropriately changed according to the incident direction of light rays and the like.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention rotatably supports a sun visor body in an upward and downward direction so that a storage state on a ceiling surface and a use state parallel to a front window surface can be selectively obtained. In the bearing device of the sun visor, the bearing device includes a support portion having a non-circular through hole formed therein, and is non-rotatable and slidable in the holder fixed to the ceiling and the through hole of the support portion of the holder. It is characterized by comprising a supporting stay that is movably inserted and a pair of sockets that are rotatably fitted to both ends of the supporting stay and that are fixed to the sun visor body.

[0009]

[Action]

 As is clear from the above structure, a non-circular through hole is formed in the supporting portion of the holder that is mounted on the ceiling, and the non-rotatable and slidable supporting station is inserted into this through hole. Since the sun visor body is connected via the rotatable sockets that are fitted to both ends of the support stay, if the vertical rotation force is applied to the sun visor body based on the support station, The socket is rotated with respect to the stay, and the sun visor body can be rotated in the vertical direction.

Further, when it is desired to change the light-shielding range of the sun visor body to the left or right, the sun visor body can be slid in either the left or right direction, and the supporting stay slides in the through hole of the supporting portion in the holder. Since it moves, the sun visor body can be slid to an appropriate position.

[0011]

【Example】

 Hereinafter, embodiments of a sun visor support device according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show a first embodiment of the present invention. FIG. 1 is a partially cutaway front view showing the overall structure of a sun visor, and FIG. 2 is an exploded perspective view showing the structure of a bearing device for a sun visor. FIG. 3 is an explanatory view showing the operation of the present invention, and FIGS. 4 to 6 are explanatory views showing another embodiment of the bearing device according to the present invention.

1 and 2, an automobile sun visor 10 equipped with a bearing device according to the present invention comprises a sun visor body 20 having a sunshade function, and a synthetic resin injection-molded body that supports the sun visor body 20 so as to be vertically movable. And a supporting stay 40 slidably supported by the holder 30 and supporting the sun visor body 20 at both ends thereof, and fixed to the sun visor body 20 so as to be rotatable at both ends of the supporting stay 40. It is composed of a pair of sockets 50 and 51 to be fitted.

More specifically, the sun visor body 20 is configured by covering the surface of a core material 21 made of a synthetic resin plate with a skin material 22 that imparts cushioning and decorative properties, and the center of the upper edge of the sun visor body 20. A recess 23 is provided in which the support stay 40 is arranged.

The holder 30 is composed of a mounting flange 31 for mounting on the ceiling 60 and a cylindrical support portion 32. The mounting flange 31 has screw holes 33 at two positions on the left and right. The support portion 32 is provided with a through hole 34 in the shape of a square hole for allowing the supporting stay 40 to be inserted therein in a non-rotatable and slidable manner.

Both ends of the supporting stay 40 inserted into the through hole 34 of the supporting portion 32 of the holder 30 are pivoted into the shaft holes 52, 53 of the pair of hollow cylindrical sockets 50, 51. The sun visor body 20 is fixed to the sun visor body 20.

Therefore, the sun visor body 20 is rotated with respect to the support stay 40 so that the sun visor body 20 can be stored in the ceiling 60 surface in a stored state and in a use state in which the sun visor body 20 is positioned parallel to the front window 61. In this case, the sockets 50 and 51 rotate at both ends of the supporting stay 40, so that the sun visor body 20 can be smoothly rotated in the vertical direction.

Further, a square hole 52a having substantially the same cross-sectional shape as the cross section of the supporting stay 40 is formed in the inner side of the shaft hole 52 of the socket 50 on one side, and the plunger 54 and the coil are formed in the square hole 52a. The spring 55 is accommodated, and the spring force of the coil spring 55 constantly urges the plunger 54 toward the end surface of the supporting stay 40, and the projection 41 is formed on the end surface of the supporting stay 40. Grooves 56 that engage with the protrusions 41 are formed on opposite end surfaces of the plunger 54.

Note that the spring force of the coil spring 55 causes the end of the supporting stay 40 to protrude from the square hole 52 a and be housed in the shaft hole 52.

When the sun visor body 20 is stored on the surface of the ceiling 60, the projection 41 of the supporting stay 40 and the groove portion 56 of the plunger 54 are fitted to each other, so that the sun visor body 20 can be securely held in the stored state. You can give the so-called click action power you can expect.

If the shape of the groove 56 formed in the plunger 54 is set to be a cross shape, a click action can be given when the visor body 20 is in use.

As described above, when the bearing device according to the present invention is used, smooth rotation operation of the sun visor body 20 in the vertical direction can be expected. However, according to the present invention, the shading range of the sun visor body 20 can be expected. The feature is that the traveling visibility of the occupant can be effectively secured according to the incident angle of the sun rays and the like.

That is, since the supporting stay 40 that supports the sun visor body 20 is slidably inserted in the through hole 34 of the supporting portion 32 in the holder 30, for example, as shown in FIG. When it is desired to shield the gap between the front window 61 and the front pillar 62 (indicated by A in the figure), the sun visor main body 20 can be slid rightward in the figure so that the supporting stay 40 for supporting the sun visor main body 20 is formed. The sun visor body 20 can be slid from the position indicated by the chain line to the position indicated by the solid line by sliding within the support portion 32 of the holder 30, and the light-shielding range can be easily changed.

Next, FIGS. 4 to 6 show a modified embodiment of the bearing device according to the present invention. FIG. 4 is a modification of the click action means, and FIGS. 5 to 6 are slide structures of the supporting stay 40. It is a modified example of.

First, FIG. 4 shows an embodiment in which a leaf spring 57 is used in place of the plunger 54 and the coil spring 55 of the first embodiment, and the leaf spring 57 is mounted in the socket 50. The chamfered portion 42 of the supporting stay 40 and the chamfered portion 57a of the leaf spring 57 are surface-bonded to each other to provide a click action. It should be noted that this embodiment has an advantage that the configuration can be simplified as compared with the first embodiment.

Next, as shown in FIG. 5, a plurality of protrusions 43 are continuously provided on the side surface of the supporting stay 40 along the longitudinal direction, and an elastic restoring force is provided at the inlet portion of the through hole 34 in the holder 30. If the pawl 35 is provided, the pawl 35 of the holder 30 is engaged with the protrusion 43 provided on the supporting stay 40 in accordance with the sliding movement of the supporting stay 40, and the sun visor body 20 is securely locked at a predetermined position. It is possible to prevent the sun visor body 20 from sliding carelessly due to vibration of the vehicle.

Similarly, as shown in FIG. 6, a pawl 36 (which may not have an elastic restoring force) is provided on the inner surface of the through hole 34 of the holder 30, and the side surface of the supporting stay 40 is provided along the longitudinal direction thereof. In order to impart flexibility to the supporting stay 40 by providing a plurality of protrusions 43, even if the opening 44 is formed, the claw 36 of the holder 30 and the protrusion 43 of the supporting stay 40 are engaged with each other, so that the sun visor is attached. The main body 20 can be securely fixed at a predetermined position.

Although each of the above-described embodiments is applied to the support device for the visor installed on both the left and right sides of the front window, it can be rotated in the vertical direction such as the center visor or the auxiliary visor in the double visor. The application does not matter as long as it has such a structure.

[0029]

[Effect of device]

 As described above, the sun visor support device according to the present invention has a structure in which the supporting stay for supporting the sun visor body is slidably inserted into the through hole of the holder fixed to the ceiling side.
