In the slide type sun visor 10 in this embodiment, the sun visor main body 20 is rotatably supported by a shaft 30, the shaft 30 is inserted and supported by a bracket 31, and the bracket 31 is attached to a ceiling portion of the vehicle body panel.
[0025]
Further, the shaft 30 is rotatably supported by a support assembly 40 that is built in the sun visor body 20. For example, in order to deploy the sun visor body 20 from the state stored in the ceiling surface to the use position on the front window side, the sun visor body 20 may be unfolded downward along the axis of the shaft 30, and the front window In order to change the light-shielding range from the side to the side window side, the shaft 30 can be rotated around the bracket 31 to be unfolded in the left-right direction.
[0026]
By the way, the sliding sun visor 10 according to the present invention is configured such that the shading range can be arbitrarily changed by sliding the sun visor body 20 along the axial direction of the shaft 30, that is, along the arrow direction in FIG. In particular, by simplifying the structure of the sliding mechanism, the manufacturing cost of the sliding sun visor 10 can be reduced, the thickness of the sun visor main body 20 can be reduced, the operability can be improved, and the support assembly 40 and the shaft 30 can be improved. It is characterized in that the tuning work with the slide mechanism part during assembly can be simplified.
[0027]
That is, the support assembly 40 includes a support main body 41 made of a resin molded body and a leaf spring 42 attached to the support main body 41. The shaft 30 is rotated by inserting the shaft 30 into the shaft hole of the support main body 41. By rotating the sun visor main body 20 around the shaft 30 with a part of the outer peripheral surface of the shaft 30 being elastically contacted by the leaf spring 42, a rotational torque force can be obtained.
[0028]
More specifically, as the structure of the sun visor main body 20, a hollow resin core material 21 is formed by joining the shell-shaped divided resin core materials 21A and 21B with the curved outer surfaces facing outwards, and this resin. The outer surface of the core material 21 is encapsulated by a sun visor skin 22 such as cloth or nonwoven fabric. In addition, the hollow resin core material 21 can also be produced as a structure in which the shell-shaped divided resin core materials 21A and 21B can be folded and joined based on the hinge portion.
[0029]
Each of the divided resin core materials 21A and 21B constituting the resin core material 21 is formed with a locking claw 23A on one side and a locking portion 23B receiving it on the other side, and the locking claw 23A and the locking portion 23B. In the present invention, guide ribs 24A and 24B for abutting and supporting the both side surfaces of the support body 41 of the support assembly 40 are provided on the inner surfaces of the divided resin core materials 21A and 21B. , 24B, the support assembly 40 is slidably supported.
[0030]
In this embodiment, guide ribs 24A and 24B are formed opposite to each other at two upper and lower portions of each divided resin core material 21A and 21B, and the distance between the guide ribs 24A and 24B is set slightly smaller than the thickness dimension of the support assembly 40. In this case, when the support assembly 40 is sandwiched between the guide ribs 24A and 24B, the elastic contact force from the guide ribs 24A and 24B is applied to the support assembly 40, so that the support assembly 40 can be surely supported and the sun visor body 20 is illustrated. 1 Can be slid in the direction of the arrow. In FIG. 2, reference numerals 25 </ b> A and 25 </ b> B denote lower ribs provided below the support assembly 40.
[0031]
Accordingly, in the slide type sun visor 10, the split resin core materials 21A and 21B made of a shell-like halved body are used as the core material of the sun visor main body 20. Therefore, the support assembly 40 is slid on the inner surfaces of the split resin core materials 21A and 21B. Since the guide ribs 24A and 24B that can be supported can be integrally formed, a conventional guide cylinder made of an aluminum extrusion-molded body or the like can be eliminated, and the cost can be reduced by reducing the number of parts and the number of mounting steps. Further, by eliminating the guide cylinder, the sun visor body 20 can be made thinner.
[0032]
Next, FIG. 3 shows a second embodiment of the sliding sun visor 10 according to the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
[0033]
This sliding sun visor 10 also has the advantage of eliminating the guide cylinder made of an aluminum extrusion molded body, etc., while at the same time achieving a more compact structure and good sliding operation during the sliding operation of the sun visor body 20. It is characteristic that it can be obtained.
[0034]
That is, the support assembly 40 that supports the shaft 30 is supported so as to be pressed from both sides by two upper and lower guide ribs 24A and 24B projecting from the inner surfaces of the hollow divided resin core materials 21A and 21B. In the second embodiment, concave grooves 43 are provided in both side surfaces of the support body 41 so as to correspond to the lower guide ribs 24A and 24B.
[0035]
Therefore, since the guide ribs 24A and 24B are fitted in the concave groove 43, the position of the support assembly 40 can be regulated in the vertical direction, and when the sun visor body 20 is slid in the longitudinal direction, the concave groove Since the guide ribs 24A and 24B move along the inside 43, there is an advantage that a smooth sliding operation can be expected.
[0036]
In the second embodiment, since the guide ribs 24A and 24B are accommodated in the concave groove 43, the clearance between the inner surfaces of the divided resin core materials 21A and 21B and the outer surface of the support assembly 40 can be set small. The thickness dimension of the sun visor body 20 can be further reduced. In addition, you may provide the concave groove 43 provided in the support main body 41 in two places up and down.
[0037]
Next, FIGS. 4 and 5 show a front view and a cross-sectional view of relevant parts of a third embodiment of the sliding sun visor 10 according to the present invention.
[0038]
Also in the third embodiment, the sun visor body 20 is constituted by the light and hollow resin core material 21 and the sun visor skin 22. However, in the third embodiment, the guide ribs 24A and 24B are not integrally formed with the divided resin core materials 21A and 21B, but a separate guide member 50 is provided.
[0039]
The guide member 50 is formed with attachment pieces 51 at two front and rear positions, and the guide member 50 is made of a resin core material by inserting a locking claw 23A provided in the divided resin core material 21A into an attachment hole 52 of the attachment piece 51. It is attached and fixed inside 21.
[0040]
The guide member 50 is formed of a synthetic resin injection molded body, and guide ribs 54A and 54B projecting from the inner surfaces of the support wall portions 53A and 53B formed upright on both sides are recessed grooves of the support assembly 40. In this configuration, the support assembly 40 is slidably supported with respect to the guide member 50 by being accommodated in the housing 43.
[0041]
Therefore, when the occupant changes the light shielding range of the sun visor body 20, if the sun visor body 20 is slid in either the left or right direction along the axial direction of the shaft 30 with respect to the shaft 30, Since the guide ribs 54A and 54B of the guide member 50 slide smoothly in the groove 43, a good sliding operation can be expected.
[0042]
And in this 3rd Embodiment, the guide member 50 can be reduced in size compared with the conventional guide cylinder body, and while being able to achieve compactness, the structure of the guide ribs 24A and 24B protruding from the inner surface of the resin core material 21 For example, the resin core material 21 is made of PP (polypropylene) resin, which is inexpensive and rich in moldability, while the guide member 50 is made of a material such as polyacetal or polyamide resin having a high surface slipperiness, etc. In consideration of functionality, the material can be properly used between the resin core material 21 and the guide member 50.
[0043]
Further, when the guide member 50 in which the support assembly 40 has been assembled in advance is assembled to the resin core material 21, the mounting operation of the support assembly 40 can be simplified by inserting the locking claw 23 </ b> A into the mounting hole 52 of the mounting piece 51. In addition, the tuning operation between the support assembly 40 and the guide member 50 can be easily performed.
[0044]
The slide support structure of the support assembly 40 shown in FIGS. 4 and 5 is configured such that the guide ribs 54A and 54B of the guide member 50 are accommodated in the concave groove 43 provided in the support assembly 40. Omitted, the guide ribs 54A and 54B of the guide member 50 may be directly elastically supported on the surface of the support assembly 40.
[0045]
【The invention's effect】
As described above, the sliding sun visor according to the present invention uses a hollow resin core material by injection molding or the like as the sun visor body, and supports the support assembly slidably by the guide rib integrally formed on the inner surface of the resin core material. Therefore, the conventional large guide cylinder can be abolished, the number of parts and the number of mounting steps can be reduced, resulting in a significant cost reduction, and the thickness of the sun visor body can be made smaller and thinner. There is an effect that an improvement in operability can be expected.
[0046]
Furthermore, according to another aspect of the present invention, a resin core material is used as the sun visor body, and a guide member that supports the slidable support assembly inside the hollow resin core material is used as the sun visor body. In place of the conventional large guide tube body, a small guide member and a member with few contact parts are used instead of the conventional large guide cylinder, so that the thickness of the sun visor body can be reduced, and the guide member and support Because there are few contact points with the assembly, the dimensional adjustment (tuning) work can be simplified, and a material that takes into account the slide holding function can be used as a guide member that is different from the resin core material. Therefore, the slide operability can be further improved.
