Description

TECHNICAL FIELD The present invention relates to a sunshade device in which a foldable sunshade cloth is used to open and close an opening, and for opening and closing an opening such as a house such as a vehicle such as an automobile. Is used for.

"Conventional Technology" As a conventional technology, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 60-51121.

That is, the publication discloses a sunshade device in which a removable glass panel is mounted on the roof of a vehicle, and a curtain member, which is a shade cloth that opens and closes below the glass panel, is provided as a sunshade device, and the curtain member has both ends of its branch line. It is disclosed that the rail is simply slidably fitted to the rail through the shoe.

[Problems to be Solved by the Invention] However, in such a conventional technique, since the branch line of the curtain member is simply guided by the rail, the curtain member does not have a function of holding the position or the state itself, and If it is not fully expanded and stretched, slack occurs, and there is a problem in that wrinkles occur in some places in the middle position and it is unsightly.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a sunshade device in which the shade cloth is well stretched regardless of the open / closed state, and there is no slack and the appearance quality is good. There is.

“Means for Solving Problems” The gist of the present invention for achieving such an object is to provide a sunshade device in which a foldable shade cloth is used to open and close the opening, and Rails facing each other and having two-step guide grooves are arranged, and the guided elements are movably fitted in the guide grooves of each step of each rail. Arranged so that the upper and lower sides are alternately arranged in the longitudinal direction of the guide groove, and the guided elements adjacent to each other in different steps are connected by link members to form a chain, and the connecting points of the corresponding link members on both side rails, Alternatively, in a sunshade device, a movable rod is installed between the movable rod and the vicinity thereof, and a key part of the shade cloth is connected to the movable rod so as to close the opening when the chain is guided by each rail and expands. You It

[Action] When the chain is extended to close the opening in the rail, three guide elements adjacent to the guide groove of each step of the rail are connected by a link member to form a certain triangle, and The positional relationship is also determined, and as long as the guided element is in the guide groove, it moves while maintaining this positional relationship.

The shade cloth is stretched by the moving rod maintained in the above-mentioned positional relationship and is opened and closed as it is without wrinkling.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

Each drawing shows an embodiment of the present invention.

As shown in FIG. 2, a sunroof device 20 including an opening 12 is provided in a ceiling 11 of a vehicle body 10 of an automobile, and a lid 21 for opening and closing the opening 12 is provided.
A sunshade device 30 for shading and the like is installed underneath.

Sunshade device 30 is a foldable shade cloth 31
The opening 12 is opened and closed at the bottom, and its detailed configuration is as follows.

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

The guided members 51, 51, ... Forming the chain 50 are movably fitted in the guide grooves 41, 42 of the respective steps of the rails 40, 40. As shown in FIGS. 4 and 5, the guided element 51 has a roller 53 pivotally supported by a pivot pin 52, and the roller 53 is rotatably fitted in the guide grooves 41, 42.

The chain 50 includes a guided element 5 on each rail 40, 40.
, 51 are arranged in the longitudinal direction so as to alternate vertically between the guide grooves 41, 42 of each step, and the guided elements 51, 51, ... The rail 40 is formed so as to be extended and expandable over the entire length of the rail 40. The link member 55 and the pivot pin 52 of the guided element 51 are rotatably connected.

In the upper guide grooves 41 of the rails 40, 40 on both sides,
A portion of the shade cloth 31 is coupled between the shaft portions 52a, 52a protruding inwardly of the pivot pins 52, 5 of the guided element 51 at the connection points of the link members 55, 55 corresponding to each other. A moving rod 32 is installed. A front panel 33 parallel to the moving rod 32 is connected to the front end of the chain 50, and a pair of front and rear guided elements 51 fitted to the rails 41 are provided on both sides of the front panel 33. It is fixed.

The connecting piece 54 is fixed to the pivot pins 52, 52 of the guided element 51 at the connecting point of the corresponding link members 55, 55 in the lower guide grooves 42 of the rails 40, 40 on both sides, and the connecting piece 54 extends upward. A moving rod 35 is installed between the shafts 54a, 54a fixedly provided at the tip of the shaft 54, and is connected to the essential parts of the shade cloth 31.

The essential points of the shade cloth 31 are connected to the moving rods 32 and 35 so that the shade cloth covers the opening 12 of the vehicle body 10 when the chain 50 is guided and deployed by the rails 40 and 40.

At the rear end of the rail 40, as can be seen from FIG. 6, the upper guide groove 41 is horizontally extended to the rear as it is, and the lower guide groove 42 is expanded downward from the enlarged portion 43 to form the link storage portion 45. Are formed.

Next, the operation will be described.

As shown in FIG. 1 and FIG. 3 (a), the shade cloth 3
From the state where 1 is folded and the opening 12 is fully opened, when the handle 34 is put on and the front panel 33 is moved forward to fully open, as shown in FIGS. 3 (b) to 3 (c). The folded link members 55, 55 of the chain 50
Is extended and separated into the guide grooves 41 and 42, and the three adjacent guided elements 51 and 51 form a constant triangle.

The chain 50 extends one after another, forming this constant triangle. Since the moving rods 32 and 35 belong to the certain triangle, the moving rods 32 and 35 move with a certain positional relationship, and the shade cloth 31 that has been folded is stretched as shown in FIG.
It is stretched and moved forward, and the opening 12 is fully closed below as shown in FIG.

When opening the sunshade device 30 in the fully closed state, the handle 3
4 is moved to move the front panel 33 backward.

As long as the guided members 51, 51 ... Are in the guide grooves 41, 42, the mutual positional relationship does not change, and they move along the guide grooves 41, 42 at a constant interval.

When the guided elements 51, 51 ... At the rear end are pushed and enter the link storage portion 45, the guided element 51 in the guide groove 41 moves rearward as it is, but the guided element 51 in the guide groove 42. Is released, the link member 55 swings around the guided element 51 in the guide groove 41, and the released guided element 51 is released.
Also, the link member 55 swings, and as shown in FIG. 3, the link members 55, 55, ... Are stored in the link storage portion 45 while being folded one after another.

The shade cloth 31 includes movable rods 32, 32 ...
, And the movable rods 35, 35 ... Are folded and stored together with the movable rods 32, 35 extending in the vehicle width direction in the ceiling of the vehicle compartment.

[Advantages of the Invention] According to the sunshade device of the present invention, the chain extending along the rail moves the link member and the guided element in a fixed positional relationship, whereby the position of the moving rod is determined. Since the shade cloth is combined and unfolded and stretched, the shade cloth stretches without sagging, and the shade cloth keeps stretched even during storage, so a sunshade device with good appearance quality Can be
