Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a sunshade device that opens and closes an opening using a foldable shade cloth.

"Conventional technology" As a conventional technology, for example, Utility Model Application No. 60-51121
There is something disclosed in the publication No.

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 is provided as a shade cloth that opens and closes below the glass panel. is simply slidably fitted to the rail through the shoe.

``Problems to be solved by the invention'' However, in such conventional technology, the branch lines of the curtain member are simply installed between the rails and guided by the rails, so when the branch lines are straight, However, if you try to hold the curtain member by raising the center part, the branch lines will fall down, making it practically impossible to hold the curtain member, and there is a problem that a middle-high shape cannot be formed.

The present invention was made in view of these conventional problems, and an object of the present invention is to provide a sunshade device in which the central part of the shade cloth can be raised and supported.

``Means for Solving the Problems'' The gist of the present invention for achieving the above purpose is that, in a sunshade device in which the opening is opened and closed using a foldable shade cloth, mutually disposed on both sides of the opening arranging rails having guide grooves facing each other, movably fitting the guided elements into the guide grooves of each rail, and forming a chain by sequentially connecting the guided elements with link members on each rail, Connection points of corresponding link members on both rails,
or between the movable beams in the vicinity thereof, so that the central part forms a mountain, and a guided member is fixed at the top of the mountainous part, and the chain is guided by each rail and unfolds. In order to close the opening, key points of the shade cloth are connected to the moving beam, and a telescoping rod is provided to connect the central part of the trailing edge of the opening to the first moving beam at the head of the chain, and the telescoping rod is connected to the moving beam. A sunshade device is characterized in that a guided member is fitted into the sunshade device.

``Operation'' When the chain is moved along the rail to open and close the shaded cloth, the moving beam moves in a mountainous position in the center, and the shaded cloth connected to the moving beam is expanded or folded.

The telescopic rod follows the movement of the chain while expanding and contracting, and the guided member of the moving beam is supported by being fitted into the telescopic rod.

When the movable beam is about to fall, the guided portion is restrained from falling by the telescopic rod, and the mountain shape is maintained.

“Embodiment” An embodiment of the present invention will be described below based on the drawings.

Each figure shows one embodiment of the present invention.

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

The sunshade device 30 is constructed by using a foldable shade cloth 31 to open and close the opening 12 from below, and its detailed configuration is as follows.

As can be seen in FIGS. 1 and 2, the aperture 12
Rails 40, 40 are arranged along both side edges 13, 13, and the rails 40, 40 have guide grooves 41 facing each other.

A chain 50 is provided in the guide groove 41 of each rail 40, 40.
The guided elements 51, 51, .

The chain 50 includes link members 55, 55, . . . guided elements 51, 51, .
It is formed so that it can be extended and deployed over the entire length of the rail 40. The link member 55 and the guided element 51 are connected to be freely rotatable.

Mountain-like movable beams 32, 32, . has been done. chain 5
At the front end of 0, there is a leading moving beam 3 parallel to the moving beam 32.
3 are connected, and on both sides thereof, a pair of front and rear guided elements 51 that fit into the respective guide grooves 41 are provided, and a hook 34 is fixed to the leading moving beam 33.

Further, a guided member 35 is fixed to the movable beams 32, 32 at the top of the mountain-shaped central portion. The guided member 35 has a base 35a fixed to the movable beam 32, and has a ring-shaped insertion hole 36 at the tip.

When the chain 50 is guided by the rails 40, 40 and unfolded, the shaded cloth 31 is exposed to the opening 12 of the vehicle body 10.
Move the key points of the shade cloth 31 to cover the beam 32.
It is combined with

The base of a base tube 62 of a telescopic rod 60 is fixed to a support plate 42 installed between the base ends of the rails 40, 40 with a fixing bracket 61.

The telescopic rod 60 is an extension pipe 6 that gradually reduces the diameter from the base pipe 62 and is fitted and connected in a telescopic manner.
3, 63... are connected in series, and the base pipe 62 and extension pipes 63, 63... are inserted into the insertion hole 36 of the guided member 35 fixed to the moving beam 32, and the leading extension pipe 63 is It is fixed to the leading moving beam 33.

A link storage section 45 is formed at the rear end of the rail 40.

Next, the action will be explained.

As shown in FIG. 1, when the shade cloth 31 is folded and the opening 12 is fully opened, the extension tubes 63, 63, . . . of the telescopic rod 60 are shortened and accommodated within the base tube 62.

When you put your hand on the latch 34 from the fully open state and move the leading moving beam 33 forward to the left in FIG. 1 to fully close it, the folded link member 5 of the chain 50
5 and 55 extend, and the guided elements 51 and 51 fit into the guide groove 41 and the link member 5 adjacent thereto.
5, 55 and the connecting pin 52 extend straight and are connected.

The chain 50 is pulled out from the link storage part 45 and extended one after another, the movable beams 32, 32... are moved in a fixed positional relationship, and the folded shade cloth 31 is extended as shown in FIG. The opening 12 of the vehicle body 10 is opened as shown in FIG.
fully close downwards.

As the leading moving beam 33 moves forward, the telescopic rod 60
When the extension tubes 63, 63, . 42 and top moving beam 33
It is built between.

When the movable beam 32 forming a mountain is about to fall, a part of the insertion hole 36 of the guided member 35 is hooked to the base pipe 62 or the extension pipe 63 of the telescopic rod 60, and the fall is suppressed.

When opening the sunshade device 30 in the fully closed state, the user puts his/her hand on the latch 34 and moves the leading moving beam 33 rearward.

As long as the guided elements 51, 51, .

When the guided elements 51, 51, . The extension pipes 63, 63, . The length is reduced to 62.

The shade cloth 31 is folded between the movable beams 32, 32, .

"Effects of the Invention" According to the sun shade device according to the present invention, when the movable beam that holds and spreads the shade cloth is formed into a mountain shape between the side edges of the opening, a telescopic rod is provided to prevent it from falling. The shade cloth can form and maintain a good curved surface, making it possible to provide a sunshade device with a good appearance.
