Abstract

PURPOSE:To prevent the slack of a shade cloth by guiding the guided elements connected in chain form by a link member, by the rails which have guide grooves in two stages and the installed on the both sides of an opened port and installing the shade at a link member connecting point, in the foldable captioned device. CONSTITUTION:When a folded shade cloth 31 is pulled out onto an opened port, a folded ring member 55 is extended successively, and three guided elements 51, 51 which are continuously separated shift in the guide grooves 41 and 42 forming a given triangle and the shade cloth 31 is extended. At this time, as far as the guided elements 51, 51 are in the guide grooves 41 and 42 the mutual position relation is kept constant, and a set interval is kept. Therefore, the shade cloth can be expanded free from slack, and outside appearance can be improved.

Description

[Detailed Description of the Invention] "Industrial Application Field" Seikan IJI relates to a sunshade device that opens and closes an opening using a foldable shade cloth, and is used for opening and closing the openings of houses, etc. as well as vehicles such as automobiles. It is used for this purpose.

"Conventional Technology" As a conventional technology, there is one disclosed, for example, in Jitsugaku No. 60-51121.

That is, the publication describes a sunshade device in which a removable glass panel is attached to the roof of a vehicle, and a curtain member serving as a shade cloth that opens and closes below the glass panel is provided. It is disclosed that the rail is simply slidably fitted to the rail through a shoe.

``Problems to be Solved by the Invention'' However, in such conventional techniques, the branch lines of the curtain member are simply guided by the rails, so they do not have the effect of maintaining their position or state by themselves, and the branch lines of the curtain member are simply guided by the rails. If it is not fully expanded and stretched, it will sag, and wrinkles will appear in places in the middle, making it unsightly.

The present invention was made by focusing on such conventional problems, and provides a sunshade device in which the shade cloth is tightly stretched regardless of whether it is opened or closed, and has no sagging and has a good appearance quality.
is intended to provide.

The gist of the present invention to achieve the above object is to provide a sunshade device in which an opening is opened and closed using a foldable shade cloth, and a sunshade device in which a foldable shade cloth is used to open and close an opening. A rail having two stages of guide grooves facing each other is arranged, and a guided element is movably fitted into the guide groove of each stage of each rail.

On each rail, the guided elements are alternately connected between the guide JMs of each stage with link members to form a chain, and a moving rod is installed between the connecting points of the corresponding link members on both rails or in the vicinity thereof. However, it is rumored that important parts of the shade cloth are connected to the moving rod so that when the sunshade cloth is unfolded while being guided by each rail, it is connected to the moving rod.

"action" Extend the chain into the rail to close the opening.

Three guided elements separated from each stage of the guide groove of the rail are connected by a link member to form a certain triangle, and the positional relationship of the moving rods is also determined, and as long as the guided element is within the guide groove. Move while maintaining this positional relationship.

The shade cloth is stretched by a moving rod that maintains the positional relationship as described above, and can be opened and closed without wrinkles.

"Example" An embodiment of the present invention will be described below based on one drawing.

Each figure shows one embodiment of the invention.

As shown in FIG. 2, a sunroof device 20 is installed in which an opening 12 is opened in the ceiling 11 of a car body 10 and a lid 21 is provided for opening and closing this opening 12.
A sunshade device 30 for shielding light is installed below.

The sunshade device 30 is a foldable shade cloth 31
The opening 12 is opened and closed from below, and its detailed configuration is as follows.

As can be seen in FIGS. 1 to 3, both side edges 1 of the opening 12
3. A pair of rails 40°40 are arranged along 13.
Both rails 40, 40 are arranged to face each other and have two upper and lower guide grooves 41, 42.

Guide for each stage of each rail 40.40 IX! Guided elements 51, 51, . . . forming the chain 50 are movably fitted into the I41, 42. As can be seen in FIGS. 4 and 5, the guided element 51 has a roller 53 pivotally supported by a pivot pin 52, and is fitted in the guide groove 41, 42 so as to be movable.

The chain 50 has a guided element 5 at each rail 40.40.
1.51... are connected alternately between the guide grooves 41, 42 of each stage by link members 55, 55-..., and are formed to be extendable and deployable over the entire length of the rail 40. The link member 55 and the pivot pin 52 of the guided element 51 are connected to be freely rotatable.

In the upper guide groove 41 of the rails 40 and 40 on both sides,
Movement to connect with key points of the shade cloth 31 between the inwardly protruding shaft portions 52a, 52a of the pivot pins 52.52 of the guided element 51 at the connection points of the corresponding link members 55.55. A rod 32 is installed. Ren fQ50
A leading panel 33 parallel to the moving rod 32 is connected to the front end of the moving rod 32, and a pair of front and rear guided elements 51 that fit into the respective rails 4 are provided on both sides. It is set up.

The connecting piece 54 is fixed to the pivot pin 52.52 of the guided element 51 at the connecting point of the corresponding link member 55.55 in the lower guide groove 42 of the rails 40.40 on both sides, and the connecting piece extends northward. A movable rod 35, which connects to key points of the shade cloth 31, is installed between the shaft portions 54a, 54a fixed at the ends of the shafts 54.

Important points of the shade cloth 31 are connected to moving rods 32.35 so that when the chain 50 is guided by each rail 40.40 and unfolded, the shade cloth puller closes the opening 12 of the vehicle body 10.

As can be seen from FIG. 6, at the rear end of the rail 40, the upper guide groove 41 extends horizontally to the rear, and the lower guide $1g142 extends downward from the enlarged part 43 to form the link storage part. 45 is formed.

Next, the action will be explained.

As shown in FIG. 1 and FIG. 3(a), the shade cloth 3
1 is folded and the opening 12 is fully opened, when the hand is placed on the latch 34 and the front panel 33 is moved forward to fully open, as shown in Fig. 3(b) to fjSa Fig. 3(c). , the folded link member 55 of the 'a chain 50.
55 extends and separates into the guide groove 41.42, and the three adjacent guided elements 51.51 form a constant triangle.

The chain 50 extends one after the other forming this constant triangle. Since the moving rods 32 and 35 belong to the certain triangle, they move according to a certain positional relationship, and the shade cloth 31I, which had been folded once, is stretched and stretched as shown in FIG. and move forward, completely closing the opening 12 downward as shown in FIG.

When opening the sunshade device 30 in the fully closed state, use the latch 3.
4 moves the leading panel 33 backward.

Guided child 51.51... is guided f! 41.42, the mutual positional relationship does not change, and the guide grooves 41.42 move along the guide grooves 41.42 at regular intervals.

When the guided elements 51, 51, . Child 51
is opened, and the link member 55 swings around the guided element 51 in the guide groove 41, and the link member 55 also swings relative to the opened guided element 51, as shown in FIG. The members 55, 55, . . . are stored in the link storage portion 45 while being folded one after another.

The shade cloth 31 has upper and lower moving rods 32, 32 and 32.
. . . and the moving rods 35, 35, .

"Effects of the Invention" According to the sunshade device according to the present invention, the chain extending along the rail moves with the link member and the guided element in a fixed positional relationship, whereby the position t is determined. Because I connected the shade cloth to the rod, unfolded it, and stretched it out.

The shade cloth stretches and spreads without sagging.

Since the shade cloth remains taut even during storage, it is possible to obtain a sunshade device with good appearance quality.
