Abstract

PROBLEM TO BE SOLVED: To ensure control of the fluttering of a sheet-shaped shield. SOLUTION: A winder 37 is provided in an opening of a vehicle body so that both side ends of a sheet-shaped shield 39 can be put in a pulled-out or wound-up condition by guidance along right and left guide rails 47, and engagement holes 45 are provided at equal intervals at both side ends of the shield 39. Racks 51 are slidably arranged in the guide rails 47, which are connected to the front end 43 of the shield 39 and engaged with the engagement holes 45 in sequence corresponding to the pull-out amount of the shield 39, when pulled out. The engagement between the engagement hole 45 and the rack 51 ensures lock of longitudinal and lateral movement.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular opening shielding device suitable for a sunroof or the like.

[0002]

2. Description of the Related Art In general, a sunroof is provided with a shielding device which serves as a sunshade inside a lid which can be opened and closed.

The shielding device is, for example, as shown in FIG.
When the sheet-shaped shield 101 is pulled out from the winding device 103 and is wound up, a fully closed state in which the vehicle body opening 105 is shielded and a fully open state in which the body opening 105 is opened are obtained. There are types that can be used.

[0004]

The sheet-type shield 101 has a rigid operation portion 107 at the front end, and both sides of the operation portion 107 can be slid by being guided by guide rails 109. Becomes In this case, both end portions of the sheet-type shield 101 are guided by the guide rails and move, but are not pinched. There was a problem of fluttering.

[0005] For this purpose, a shield 1 made in a sheet shape is used.
Various means have been devised to suppress the fluttering of 01, but at present there is no reliable means.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vehicular opening shielding device capable of reliably suppressing fluttering of a shielding body.

[0007]

In order to achieve the above object, according to the present invention, both ends of a sheet-shaped shield are guided by left and right guide rails into an opening of a vehicle body. The shield has a winding device that is pulled out and wound up, and is provided with equally spaced engagement holes at both side ends of the shield, while the front end of the shield is provided in the guide rail. When the shield is pulled out, the racks that sequentially engage with the engagement holes are slidably disposed in accordance with the amount of the pull-out.

[0008] Thus, the fully open state of the opening can be obtained by fully pulling out the front end of the shield by hand, and the fully open state of the opening can be obtained by winding the shield around the winding device. Will be able to

On the other hand, when the shield is fully pulled out and fully closed, the engagement holes of the shield engage with the rack.

Therefore, both ends of the shield are reliably restrained from moving in the front-rear direction as the drawing direction and the left and right direction as the vehicle width direction, and are thus affected by wind, negative pressure, vibration and the like. No fluttering occurs.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIGS.

In FIG. 5, reference numeral 1 denotes a roof opening provided in the roof panel 3.

The roof opening 1 is provided with a lid 5 made of a transparent or translucent material, and a shielding device 7 which serves as a shade inside the lid 5. The lid 5 can be slid back and forth along the guide rail 9 between a fully closed state located at the roof opening 1 and a slide opening state retracted from the roof opening 1.

The guide rail 9 is formed in an inverted U-shape arranged from the front area of the roof opening 1 to the area on both sides thereof, and a cross member 11 is bridged on the rear end side which is both free end sides. ing.

As shown in FIG. 3, the guide rail 9 has a vertical wall 15 vertically rising from a substantially horizontal base portion 13, and
Further, the flange portion 17 has a crank-shaped cross section extending to the side, and the base portion 13 is provided with left and right rail portions 21 having a cable guide groove 19. Between the rail part 21 and the vertical wall 15 is a gutter part 23 for guiding rainwater or the like into the drain hole.

The lid 5 is mounted on a bracket 29 supported by a front moving shoe 25 and a rear moving shoe 27 which can slide back and forth between the rail portions 21 of the guide rail 9 as shown in FIG. The front moving shoe 25 is for support. Rear moving shoe 27
Has an elevating arm 31, and the arm pins 31a, 31b in front and behind the elevating arm 31 slide in the left and right guide grooves 33, 34 to move the rear end side of the lid 5 up and down. The cable guide groove 1 of the rail portion 21 has a lifting function for tilting down.
The drive is controlled so as to be slidable back and forth by a geared cable 35 running in the inside 9.

The operation of the geared cable 35 is controlled by a drive motor M which can be rotated forward and backward by a hand switch.

On the other hand, the shielding device 7 comprises a winding device 37 and a shielding body 39. The winding device 37 is supported at both ends by fixing members 41 provided on the guide rail 9.

The shield 39 is always urged in the winding direction by the winding drum of the winding device 37 (not shown).
And can be pulled out freely. The winding device 37 is locked at the stop position when the drawer is slowly stopped at a position where the shield 39 is pulled out by a predetermined amount, and is locked when the shield 39 is pulled forward again from the stop position. It is to be released.

As shown in FIGS. 1 and 2, the front end of the shield 39 is provided with a rigid body such as a rod inside, and serves as an operation unit 43 for manual operation.

Both ends of the shield 39 have vertically extending engaging holes 45 provided at predetermined intervals, and are provided with rail grooves 47a of a second guide rail 47 formed in a C-shaped cross section.
, And slide movement is possible.

The second guide rail 47 is formed separately from the guide rail 9 for the lid.
Engagement projection 49 which engages with the engagement hole 45 in a detachable manner.
Is provided. The second guide rail 47 is provided with an engagement protrusion 49 of the rack 51 and an engagement hole 45.
A substantially horizontal engagement area L1 where
1 and a standby area L2 bent into a hairpin shape. The engagement area L1 is fixedly supported by the base portion 13 of the guide rail 9.

The rack 51 is made of a flexible material. The front end of the rack 51 is integrally fixed to both sides on the front end side of the shield 39, which serves as the operation section 43. Can be put in and out through a cutout opening 53 provided in the hairpin region.

On the other hand, the rear end of the rack 51 is a free end extending from the hairpin area of the second guide rail 47 toward the standby area L2.

According to the shielding device 7 configured as described above, when the operating section 43 is manually operated in the direction of the arrow in FIG. 1, the shielding body 39 is pulled out from the winding device 37, and the shielding state of the roof opening 1 is obtained. . At this time, the rack 51 slides from the standby area L2 to the engagement area L1 and the engagement protrusions 49 are sequentially engaged with the engagement holes 45 in accordance with the amount of withdrawal of the shield 39. become.

With this arrangement, when the shield 39 is fully closed when the shield 39 is closed, the engagement holes 45 at both ends are engaged with the engagement protrusions 4.
9, the movement in the left-right direction, ie, the front-rear direction and the vehicle width direction, is reliably restrained, so that there is no fluttering due to the influence of wind, negative pressure, vibration, etc. Will be able to

In this embodiment, the shield 39 is described as a sunshade provided in the roof opening 1. However, the sunshade 39 can be used as a sunshade for a window glass or a tonneau cover.

[0028]

As described above, according to the present invention, at the time of shielding, the engaging holes at both side ends of the sheet-shaped shield are engaged with the rack, so that they can be moved in the front-rear and left-right directions. Since the movement is reliably restrained, it is possible to reliably prevent the shield from fluttering. Thereby, a high quality feeling can be obtained.
