【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, parts common to those in the description of the prior art section will be described using common reference numerals, and the same reference numerals will be given to the same members in the drawings. Example 1 FIG. 1 is a side view of a sun visor bearing stand 5A having a hook-shaped bearing portion 11A for receiving the support shaft 4 of the sun visor 1 described in the section of the prior art. 2 is a perspective view of an opening portion of the through hole 17 existing on the surface 22 opposite to the surface 12 in contact with the vehicle body ceiling portion 2, and FIG. 3 is a temporarily fixed sun visor bearing stand 5A of the first embodiment. FIG. 4 is a front view of the sun visor bearing stand 5A of the first example attached to the vehicle body ceiling portion 2.

As shown in FIG. 1, the sun visor bearing stand 5 A has a bar-shaped guide piece 6 similar to the conventional sun visor bearing stand 5 formed on the surface 12 in contact with the vehicle body ceiling 2. 6 is inserted into a guide hole 7 that is opened in advance in the vehicle body ceiling 2. Further, the engaging piece 14 integrally formed with the surface 12 is inserted into a mounting hole 13 previously opened in the vehicle body ceiling portion 2, and when locked to the hole 13, the sun visor bearing stand 5A is attached to the vehicle body ceiling portion. It is fixed to 2. The engaging piece 14 is made of a synthetic resin having appropriate elasticity and hardness, and has a split groove 15 that can be elastically expanded. Further, a through hole 17 is formed in the central shaft portion of the engaging piece 14. The insertion piece 16 described later is inserted into the through hole 17.

As shown in FIG. 2, a surface 22 opposite to the surface 12 in contact with the vehicle body ceiling portion 2 has an insertion port 20 which is an opening portion of the through hole 17 and which is an entrance into which the insertion piece 16 is inserted. In the present Example 1, in this insertion hole 20 having a substantially square shape, one temporary fixing portion 21 is provided at the target side position, and a strip shape is formed along the edge in the inward direction of the insertion opening 20. Is installed in the area. The positions of the temporary fixing portions 21 and 21 are two surfaces which are different by 90 degrees from the direction in which the side surface of the engaging piece 14 does not exist due to the through hole 17, and are made of synthetic resin having appropriate elasticity and hardness.

As shown in FIG. 4, the outer surface central portion 14A of the engaging piece 14 centering on the split groove 15 is formed in a V shape in cross section, while the proximal end portion is formed with a collar portion 14B. . Then, when the outer surface central portion 14A passes through the mounting hole 13 of the vehicle body ceiling portion 2 which is made smaller than the width dimension of the outer surface central portion 14A, the split groove 15 elastically contracts, so that the engaging piece 14 is inserted into the mounting hole 13 up to the flange 14B. When the insertion piece 16 is pushed to a predetermined position in the through hole 17 in this manner, the split groove 15 is elastically expanded, and the concave portion between the outer surface central portion 14A and the flange portion 14B is pressed against the inner diameter surface of the mounting hole 13. Therefore, the visor bearing stand 5A is fixed to the vehicle body ceiling 2.

FIG. 5 is a plan view of the insertion piece 16, FIG. 6 is a front view of the insertion piece 16 of the first example, and FIG. 7 is a right side view of the insertion piece 16 of the first example. As shown in FIGS. 5, 6 and 7, the base end portion 16A of the insertion piece 16 is formed in a substantially quadrangular and inclined shape. Further, the shaft portion 16B integrally formed with the base end portion 16A has a substantially rectangular cross section, and the widened portion 16C is formed at the tip end. Further, the base end portion 16A is integrally formed with a protrusion 16D for adjusting the insertion position along each side of the shaft portion 16B. Then, on the two side surfaces of the shaft portion 16B at a predetermined position apart from the widened portion 16C in the direction of the base end portion 16A by 90 degrees, the two insertion portions 16 of the first embodiment have two provisional fixing convex portions 16E, Each 16E is molded. The temporary fixing projections 16E and 16E correspond to the locking portions in claims 1 and 2.

The insertion piece 16 formed as described above is pushed a little upward in the drawing from the insertion opening 20 of the through hole 17 of the engagement piece 14 as shown in FIG. The insertion pieces 16 are temporarily fixed to the engagement pieces 14 by locking the 16E 1 and 16E 1 while being positioned above the temporary attachment portions 21 and 21, and the insertion pieces 16 are inserted into the through holes 17 of the engagement pieces 14. It stops at and does not fall. At this time, the widened portion 16C at the tip of the insertion piece 16 rarely projects from the outlet of the through hole 17 in the direction of the surface 12 in contact with the vehicle body ceiling portion 2, and the insertion groove 16 is elastically expanded by the insertion of the insertion piece 16. There is no such thing. Therefore, the elasticity of the split groove 15 is prevented from lowering even when it is stored for a long time in the temporarily fixed state. In this temporarily fixed state, the insertion piece 16 stops in the through hole 17 of the engagement piece 14 and does not fall. Therefore, the insertion piece 16 which is an accessory member of the sun visor bearing stand 5A of the first example is integrally formed. It is convenient to transport and manage. It should be noted that only one provisional fixing portion 21, 21 may be provided on one side of the insertion port 20, and only one provisional fixing convex portion 16E may be provided, and each one of these provisional fixing convex portions 16E and The insertion piece 16 is temporarily fixed to the engagement piece 14 by the temporary fixing portion 21. However, the insertion piece 16 is more stably fixed to the engaging piece 14 when two pieces are provided as in the first embodiment.

As described above, from the state where the insertion piece 16 is temporarily fixed to the engagement piece 14 as shown in FIG. 3, the insertion piece 16 is pushed further upward in the drawing, and as shown in FIG. When the insertion groove 16 is pushed to the position, the widened portion 16C of the insertion piece 16 is projected to the outside of the engagement piece 14, and the split groove 15 is elastically closed so that the widened portion 16C does not come off. As described above, when the insertion piece 16 is inserted into the through hole 17 of the engaging piece 14 in a state where the sun visor bearing stand 5A is positioned at the predetermined position of the ceiling portion 2 and is pushed to the predetermined position, the sun visor bearing stand 5A. Is fixed to the vehicle body ceiling portion 2, so that the sun visor bearing 5A can be attached to the vehicle body ceiling portion 2 very easily. In this state, the widened portion 16C of the insertion piece 16 serves as a stopper, so that the mounting or loosening of the sun visor bearing stand 5A can be prevented.

Example 2 The sun visor bearing base of Example 2 is shown in FIG. 8 in place of the temporary fixing projections 16E and 16E at the same positions as the temporary fixing projections 16E and 16E formed on the insertion piece 16. Thus, only the point that the provisional fixing claw portions 16F, 16F are formed is different from the first embodiment. The temporary fixing claw portions 16F, 16F correspond to the locking portions in claims 1 and 2. As in the first embodiment, the provisional fastening claw portions 16E, 16E are locked in a state of being positioned above the provisional fastening portions 21, 21, so that the insertion piece 16 is provisionally fixed to the engagement piece 14, and the insertion piece 16 is inserted. 16 is stopped in the through hole 17 of the engaging piece 14 and is in a state where it does not fall. Therefore, the same effect as the sun visor bearing stand of the first embodiment is obtained. As in the first embodiment, the temporary fixing claw portion 16E and the temporary fixing portion 21 may be one each. Although the convex shape and the claw shape are illustrated as the locking portion and the band shape is illustrated as the temporary fixing portion 21 in the present specification, the locking portion is locked by the temporary fixing portion 21, whereby the insertion piece 16 is If the insertion piece 16 is temporarily fixed to the engagement piece 14 and remains in the through hole 17 of the engagement piece 14 and does not fall, the locking portion and the temporary fixing portion 21 may have other shapes.

Embodiment 3 As shown in FIG. 9, in the sun visor bearing stand of Embodiment 3, an elastic groove portion 16G is further formed in the central shaft portion of the insert piece 16 made of a synthetic resin having appropriate elasticity and hardness. The only difference is the difference from the first embodiment. The elastic groove portion 16G is provided on two side surfaces different from the side surface of the insertion piece 16 on which the temporary fixing projections 16E, 16E are formed. Since the groove portion 16G is elastically contracted and closed due to the existence of the groove portion 16G, the insertion piece 16 is easily inserted into the through hole 17. The elastic groove portion 16G may be provided in the insertion piece 16 of the second example.

Fourth Embodiment FIG. 10 shows a sun visor bearing stand according to the fourth embodiment. In the fourth embodiment, temporary fixing portions 21 and 21 are formed in an insertion opening 20 which is an opening portion of a through hole 17. The difference from Example 1 is that it is not included. In the sun visor bearing stand according to the fourth embodiment, as shown in FIG. 10, the insertion piece 16 is inserted by being pushed a little upward in the drawing from the insertion opening 20 of the through hole 17 of the engagement piece 14, and the temporary fixing convex portion is inserted. The insertion pieces 16 are temporarily fixed to the engagement pieces 14 by locking 16E and 16E in the state of being located above the peripheral edge of the opening formed in the upper part of the sun visor bearing stand by the through holes 17. The insertion piece 16 is locked in the through hole 17 of the engagement piece 14 so as not to fall. At this time, the widened portion 16C at the tip of the insertion piece 16 rarely projects from the outlet of the through hole 17 in the direction of the surface 12 in contact with the vehicle body ceiling 2, and the insertion groove 16 is elastically expanded by the insertion of the insertion piece 16. Is reduced. Therefore, the elasticity of the split groove 15 is less likely to decrease even when it is stored in the temporarily fixed state for a long time. Then, as in the case of the first embodiment, the insertion piece 16 is pushed further upward in the drawing from the state in which the insertion piece 16 is temporarily fixed to the engagement piece 14 as shown in FIG. 10, and is pushed to a predetermined position inside the through hole 17. Then, the widened portion 16C of the insertion piece 16 is projected to the outside of the engagement piece 14, and the split groove 15 is elastically closed so that the widened portion 16C does not come off. Therefore, the sun visor bearing stand of the fourth example produces the same effects as those of the sun visor bearing blocks of the first to third examples. Further, the sun visor bearing stand of the present example 4 does not need to form the temporary fixing portions 21 and 21 in the insertion port 20, so that the sun visor bearing stand of the present example 1 to the present example 3 can be produced more easily. The elastic groove portion 16G may be provided in the insertion piece 16 of the fourth embodiment. In this case, since the elastic groove portion 16G elastically contracts and contracts, the insertion piece 16 is easily inserted into the through hole 17.
