BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding sunshade opening / closing device mounted on a vehicle interior side of a sunroof of a vehicle, and more particularly to an improvement of a slide holder for mounting the sunshade slidably on a rail.

[0002]

2. Description of the Related Art Conventionally, a sunshade opening / closing device of this type includes a window opening formed in a roof panel of a vehicle body,
A sliding sunshade that opens and closes the window opening, a pair of rails provided along two opposing opening edges facing the interior side of the window opening, and fixed to both ends of the sunshade, respectively. There has been known one provided with a plurality of slide holders that individually slide on rails (for example, Japanese Utility Model Laid-Open No. 1-81321, Japanese Utility Model Laid-Open No. 1-9).
No. 0611, Japanese Utility Model Laid-Open No. 1-104815, Japanese Utility Model Laid-Open No. 1-165715, Japanese Utility Model Laid-Open No. 2-21026, Japanese Utility Model Laid-Open No. 2-21028, Japanese Utility Model Laid-Open No. 2-6821.
No. 1, Japanese Patent Publication No. 2-40523).

[0003] In the conventional slide holder, an elastic body such as rubber or a leaf spring is fixed to the slide holder in order to prevent rattling of the sunshade during running of the vehicle.
Alternatively, a spring piece utilizing the elastic restoring force of resin or metal is integrally formed, and these elastic bodies and spring pieces are elastically slidably contacted with the rail.

[0004]

However, the above-mentioned conventional slide holder has a problem that its structure is complicated. For example, when an elastic body such as rubber or a leaf spring is fixed, there is a disadvantage that the number of parts increases and the manufacturing process of the slide holder increases. Also, when the spring piece is formed integrally with the slide holder, the spring piece is merely for preventing the backlash of the sunshade, and the structure of the slide holder becomes complicated by the amount of the spring piece. This leads to an increase in manufacturing cost.

Therefore, a vehicle sunshade opening / closing device according to the first aspect has been made in view of the above-mentioned problems of the prior art.
It is an object of the present invention to provide a slide holder which is not only capable of attaching the sunshade to the rail without play, but also has a simple structure and is easily attached to the sunshade.

[0006]

SUMMARY OF THE INVENTION The present invention is to achieve the above-mentioned object, and its contents will be described below using embodiments shown in the drawings. The invention according to claim 1 has the following four configurations. First, the slide holder (50) is attached to each rail as shown in FIGS.
(40) A slide base (70) that slides on, and a fitting part that is separated upward from the slide base (70) and has a fitting groove (81) into which each end of the sunshade (30) is fitted.
(80), at least one pair of protrusions (90) projecting from the inner surfaces facing each other across the fitting groove (81) of the fitting portion (80) and facing each other into the fitting groove (81). , The slide base (70)
With connecting fitting portion (80) to each other and said pair of collision
The elastic portion (100, 110) is configured such that the raised portions (90) have elasticity in directions approaching each other and in a vertical direction.

Further , the slide holder (50) is
It is molded in one piece. Second, slide base (70)
For example, as shown in FIGS. 1 and 2, rails (4
(0) A pair of guide pieces vertically downward along both side edges
(71, 71) are formed respectively. Third, a pair of protrusions
The upper end of the part (90) has a tapered surface that opens upward
(91) are formed.

Fourth, the elastic connecting portions (100, 110)
(30) has a hollow structure that expands in the thickness direction.
You. In addition, the elastic connecting portions (100, 110) are
0) The thickness of the sunshade (30) from both ends in the width direction
A pair of curved pieces (101, 111) that are curved while bulging in the direction
have.

[0009]

Therefore, according to the opening and closing device of the first aspect, each end of the sunshade (30) is fitted into the fitting groove (81) of each slide holder (50) to thereby provide the sunshade (30). ), Each slide holder (50) is attached to both ends. When each end of the sunshade is fitted into the fitting groove (81) of the slide holder (50), the front and back surfaces of the sunshade have at least a pair of protrusions (90, 90) projecting oppositely into the fitting groove. Respectively.

Here, when the sunshade is strongly pushed into the fitting groove, the respective protrusions are pressed against the front and back surfaces of the sunshade, and the elastic connecting portions (100, 110) are flexibly elastically bent. The groove is expanded , that is, a pair of protrusions (9
0) are separated from each other. I do. For this reason, each end of the sunshade advances in the expanded fitting groove and fits into the fitting groove. When each end of the sunshade fits into the fitting groove, the elastic connecting portion has a pair of protrusions due to its elasticity.
The starting portions (90) try to restore in a direction approaching each other . For this reason, both ends of the sunshade are held in the fitting grooves of the slide holder so that the two protrusions bite into the front and back surfaces of the sunshade, respectively.

Thus, each slide holder is mounted on each end of the sunshade. Next, the slide bases of the respective slide holders respectively attached to both ends of the sunshade are mounted on the respective rails (40), so that the sunshades are slidably mounted on both rails via the slide holders.

On the other hand, with respect to vibration and the like during running of the vehicle,
Since the elastic connecting portion of the slide base flexibly bends in the vertical direction, the vibration can be absorbed, and rattling of the sunshade in the vertical direction can be prevented .

1 is a side view of a slide holder, FIG. 2 is a perspective view of the slide holder, FIG. 3 is a plan view of the slide holder, and FIG. The sectional views along the line VI are shown. In FIG. 1, reference numeral 10 denotes an opening / closing device for a vehicle sunshade. The device 10 includes a window opening 20 formed in a roof panel (not shown) of a vehicle body and a window opening 20 formed in the roof panel (not shown).
A sliding sunshade 30 that opens and closes 20, a pair of rails 40 provided along two opposing opening edges facing the interior side of the window opening 20, and fixed to both ends of the sunshade 30, respectively. And a plurality of slide holders 50 that individually slide on both rails 40.

Although not shown, a sunroof is mounted on the window opening 20. The sunshade 30 is curved in an arc shape along the roof panel of the vehicle body, and has substantially the same size as the window opening 20, as shown by a dashed line in FIG. Then, nonwoven fabrics 60 covering the edges are joined to both lower ends of the sunshade 30. The rail 40
Is longer than the edge of the window opening 20 and slides the sunshade 30 along the rail 40 so that the window opening 20 can be opened and closed by the sunshade 30.

The slide holder 50 includes a slide base 70 that slides on each rail 40, a fitting portion 80 that is separated upward from the slide base 70, and has a fitting groove 81 into which each lower end of the sunshade 30 is fitted. At least one pair of projections 90 projecting from inside surfaces facing each other across the fitting groove 81 of the fitting portion 80 so as to face each other in the fitting groove 81.
, And elastic connecting portions 100 and 110 which connect the slide base 70 and the fitting portion 80 to each other and have elasticity in a direction in which the fitting groove 81 is closed and in a vertical direction.

The slide holder 50 has appropriate elasticity and rigidity and relatively low frictional resistance, for example, P
It is integrally formed of plastic such as P (polypropylene). As shown in FIGS. 1 and 2, the slide base 70 has a rectangular plate shape that is long in the longitudinal direction of the rail 40.
A pair of guide pieces 71, 71, each of which is vertically provided with a short U-shaped cross section, are formed at both ends thereof along both side edges of the rail 40.

The fitting portion 80 is, as shown in FIGS.
It is formed of a pair of side walls 82 and 83 facing upward away from each other in the thickness direction of the sunshade 30, and a bottom wall 84 connecting the lower ends of the side walls 82 and 83 to each other. I have. As shown in FIG. 1, the facing distance between the side walls 82 and 83 is wider than the thickness of the sunshade 30 and is set to be equal to the thickness of the sunshade 30 plus the thickness of the nonwoven fabric 60 folded on the front and back surfaces of the sunshade 30. ing.

As shown in FIGS. 1 and 2, the bottom wall 84 faces upward from the upper surface of the slide base 70. Then, an arc-shaped depression is formed in the bottom wall 84, and a thin portion 85 is formed in the bottom wall 84 by the depression. The fitting groove 81
As shown in FIGS. 1 and 2, is formed inwardly surrounded by both side walls 82 and 83 and a bottom wall 84, and its upper surface and both ends are open.

As shown in FIGS. 1 to 4,
It has a substantially triangular prism shape extending vertically, and is projected from both ends of the inner side surfaces of both side walls 82 and 83, respectively, to form a total of four pieces.
More specifically, each protrusion 90 has a right-angled triangular cross section, and one surface thereof is flush with the end surfaces of the side walls 82 and 83. Also, both projections facing each other across the fitting groove 81
The distance between the apexes of the 90 triangles is set substantially equal to the thickness of the slide base 70.

At the upper end of each projection 90, a tapered surface 91 which opens upward is formed so that the end of the sunshade 30 can be easily inserted into the fitting groove 81. As shown in FIG. 1, the elastic connecting portions 100 and 110 are located on the outdoor side and the indoor side, respectively, and form a hollow structure that expands in the thickness direction of the sunshade 30. More specifically, each elastic connecting portion
100 and 110 extend upward from both ends in the width direction of the slide base 70 while being curved in an arc shape, and the side walls 82 and 83
A pair of curved pieces 101 and 111 facing each other at a distance outside
And a slide base 70 for connecting the upper ends of the curved pieces 101 and 111 and the upper ends of the side walls 82 and 83 facing each other.
And a pair of horizontal pieces 92 and 102 which are parallel to the horizontal axis.

As shown in FIGS. 1 and 2, reinforcing ribs 103 and 113 are formed on the inner surfaces of the curved pieces 101 and 111, respectively. I have. Also, both horizontal pieces 102, 112 are shown in FIGS.
As shown in FIG. 3, the horizontal pieces 112 on the indoor side located on the right side in FIG. 1 are formed narrower than the horizontal pieces 102 on the outdoor side located on the left side in FIG. Therefore, the fitting portion 80 of the slide holder 50 is located closer to the indoor side on the right side in FIG. 1, and the elastic connecting portion 110 located on the same indoor side is less likely to bend than the elastic connecting portion 100 located on the outdoor side. Has become.

Next, the slide holder 50 having the above configuration is attached to each lower end of the sunshade 30. Although not shown, a plurality of slide holders 50 are attached to one end of the sunshade 30 at appropriate intervals along the longitudinal direction. First, the sunshade
Each lower end of 30 is fitted from above in alignment with the upper surface of the opening of the fitting groove 81 of the slide holder 50. At this time, the slide holders 50 are fitted so that the elastic connecting portions 100 of the slide holder 50 located on the left side in FIG. 1 are located outside the lower ends of the sunshade 30 in the facing direction.

When the lower ends of the sunshade 30 are fitted,
Four protruding portions where the surface of the nonwoven fabric 60 which is folded and bonded to the front and back surfaces of the sunshade 30 is opposed to the fitting groove 81 and protrudes.
90 respectively engage with each tapered surface 91. Here, when the sunshade 30 is strongly pushed into the fitting groove 81, each tapered surface 91 is pushed through the surface of the nonwoven fabric 60, so that both side walls 82 and 83 are centered on the thin portion 85 of the bottom wall 84. Then, the groove width at the opening end of the fitting groove 81 is widened.

At this time, the two elastic connecting portions 100 and 110 connected to the respective upper ends of the side walls 82 and 83 are bent so as to expand outward. Therefore, the sunshade 30 needs to be pushed into the fitting groove 81 against the elastic restoring force of the resin of the elastic connecting portions 100 and 110. When the groove width at the open end of the fitting groove 81 is expanded, each lower end of the sunshade 30 is
At the same time, it proceeds along the tapered surface 91 into the fitting groove 81,
A dead end hits the bottom wall 84 of the fitting groove 81.

Then, as the sunshade 30 progresses, the two side walls 82,
Due to the closing force of the 83, the triangular pointed end of the fitting groove 81 of each projection 90 bites into the nonwoven fabric 60. For this reason, as each protrusion 90 bites into the nonwoven fabric 60, each lower end of the sunshade 30 is held in the fitting groove 81 as shown in FIG.

Thus, at both lower ends of the sunshade 30,
After each slide holder 50 is mounted, the slide base 70 of each slide holder 50 is mounted on both rails 40 as shown in FIG. At this time, the rail 40 is positioned and placed within the space between the two guide pieces 71 of the slide base 70. When the slide base 70 is placed in this manner, the two guide pieces 71 abut on both side edges located on both sides in the width direction of the rail 40, so that the slide holder 50 does not come off in the width direction of the rail 40. The sunshade 30 is mounted on both rails 40 via.

The distance from each lower surface including the nonwoven fabric 60 of the sunshade 30 to each upper surface of both rails 40 is determined by the distance from the upper surface of the bottom wall 84 of the fitting groove 81 of the slide holder 50 to the slide base.
By setting the distance to be slightly longer than the distance to the lower surface of 70, both elastic connecting portions 100 and 110 bend slightly in the vertical direction. For this reason, the lower surface of the slide base 70 is
Elastically abut against each upper surface.

Incidentally, even when the accuracy of the components such as the sunshade 30, the rail 40 and the slide holder 50 and the mounting accuracy thereof are not sufficient, the sunshade 30 can be flexibly bent in the vertical direction. Can absorb backlash. And sunshade 30
When the lower surface of the slide base 70 of the slide holder 50 slides on the rail 40, the slide base slides along the longitudinal direction of the two rails 40 to open the window opening 20 formed in the roof panel (not shown) of the vehicle body. Open and close.

On the other hand, with respect to vibration and the like during running of the vehicle,
When the elastic connecting portions 100 and 110 of the slide base 70 flex elastically in the vertical direction, the vibration can be absorbed and the sunshade can be prevented from rattling in the vertical direction. In the slide holder 50 shown in the drawings, the fitting groove 81 is formed in a U-shape with an open upper surface, but may be formed in a U-shape.

Although the projections 90 are projected in a triangular prism shape, a total of four projections 90 are used. However, the cross-sectional shape of the projections 90 is not limited to a triangle, but may be a waveform or a convex shape. It is sufficient that at least one pair sandwiches the fitting groove 81, and furthermore, both side walls 82, 83
May be formed in a cross-sectional waveform or uneven shape on each inner surface of the
Alternatively, needles may be scattered on the inner surfaces of both side walls 82 and 83.

Further, although the elastic connecting portions 100 and 110 are formed on both sides of the slide holder 50, they may be formed on only one side thereof. Further, although both elastic connecting portions 100 and 110 are curved in an arc shape, they may be bent in a V-shape or may be bent in multiple stages.
