Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail structure for supporting a sunshade provided inside a sunroof of an automobile.

[0002]

[Prior art]

 Inside the sunroof provided on the roof of an automobile, a plurality of sunshades (15) to (17) are generally provided as shown in FIG. 3 for sun protection (see Japanese Utility Model Laid-Open No. 58-25722). . These sunshades (15) to (17) are supported and guided at both ends by a pair of rail members (18) attached to both sides of an opening (A ') of a roof panel (not shown). Slide in the direction (the left side of the drawing is the front). Among the sunshades (15) to (17), the front sunshade (15) has front and rear end portions provided with locking portions (19) and (20) projecting upward. A protruding portion (21) provided downward at the front end portion of the central sunshade (16) is engaged between the portions (19) and (20).

In the above structure, when the central sunshade (16) and the rear sunshade (17) are slid in the direction of the arrow, the projecting portion (21) of the central sunshade (16) and the front end of the front sunshade (15) will eventually come out. The front side sunshade (15) slides forward while following the central sunshade (16) by engaging with the side locking portion (19). As a result, the sunshades (15) to (17) reach the door open position indicated by the chain double-dashed line, and the opening (A ') is opened. If the center sunshade (16) and the rear sunshade (17) are slid in this direction from this state, the front sunshade (21) is engaged by the engagement of the rear end side locking part (20) and the protruding part (21). 15) follows the central sunshade (16) and slides backward, and each sunshade (15) to (17) reaches the closed position indicated by the solid line and closes the opening (A ').

As shown in FIG. 4, the conventional rail member (18) is formed in an E-shaped cross section integrally including a main rail (23) and a sub rail (24). Then, the side ends of the central and rear sunshades (16) (17) are fitted into the upper main rail (23), and the side ends of the front sunshade (15) are fitted into the lower auxiliary rail (24). Is fitted.

[0005]

[Problems to be solved by the device]

 In this way, the front sunshade (15) slides between the closed door position and the open door position guided by the auxiliary rail (24), but its movement range is within the area (S ') shown in FIG. Is limited to. Therefore, it is sufficient that the sub rail (24) is formed in the area (S ') in the figure, and the sub rail (24) located behind this area (S') is originally unnecessary. is there.

However, conventionally, the rail member (18) is formed by extrusion molding of a resin or the like in consideration of ease of molding and the like. Therefore, the cross-sectional shape of the rail member (18) is E-shaped uniformly over the entire length thereof, and the sub rail (24) is always formed behind the area (S '). Therefore, in the conventional rail structure, there are problems that the consumption of resin or the like as the raw material of the rail increases and the vehicle weight increases.

Therefore, an object of the present invention is to provide a rail structure of a sunshade that can save the amount of raw materials used and can also reduce the weight of a vehicle body.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a rail structure having a rail member for supporting a plurality of sunshades arranged in different stages, the rail member being a main rail and a sub-rail mounted on the main rail. The auxiliary rail is formed to have a length substantially equal to the moving distance of the sunshade supported by the auxiliary rail.

[0009]

[Action]

 Since the rail member is composed of the main rail and the sub rail attached to the main rail, and the sub rail is formed to have a length substantially equal to the movement distance of the sunshade supported by the sub rail, Outside the movement range of the sunshade supported by the rail, the auxiliary rail is deleted. This makes it possible to save raw materials and reduce the weight of the vehicle body.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1, a pair of rail members (1) are attached to both sides of an opening (A) provided in a roof panel (not shown) (one rail member is not shown). The three sunshades (2) to (4) arranged in different stages are supported by the rail member (1) and are slidable in the front-rear direction. The front sunshade (2) and the central sunshade (3) are formed with locking portions (5) (6) and a protruding portion (7), respectively, as in the conventional product. ) (6) and the protrusion (7) are engaged, the front sunshade (2) slides in the front-rear direction following the central sunshade (3).

As shown in FIG. 2, the rail member (1) has a cross section L formed by fastening means such as rivets on a vertical portion (9a) of the first rail member (9) having an F-shaped cross section. It is configured by mounting a second rail member (10) having a character shape. Thus, the main rail supporting the central sunshade (3) and the rear sunshade (4) between the upper horizontal part (9b) and the lower horizontal part (9c) of the first rail member (9). (11) is configured, and the front sunshade (2) is provided between the lower horizontal portion (9c) of the first rail member (9) and the horizontal portion (10a) of the second rail member (10). An auxiliary rail (12) for supporting the vehicle is constructed. That is, the rail member (1) is formed in a two-stage structure integrally including the main rail (11) and the sub rail (12).

The first rail member (9) and the second rail member (10) are separately formed by extrusion molding of resin, metal, etc., and at this time, the second rail member (10) Is formed to have substantially the same length as the moving range (s) of the front sunshade (2). As a result, the sub rail (12) has substantially the same length as the movement range (s) of the front sunshade (2), and the sub rail behind the movement range (s) is deleted. Therefore, compared to the conventional product, the amount of rail raw materials (resin, metal, etc.) used is reduced by this amount, and the weight of the vehicle body can be reduced.

Although the above description relates to a rail structure that supports three sunshades (2) to (4), the present invention is not limited to this, and two sunshades arranged in different stages can be used. It can be widely applied to a rail structure for supporting four or more sunshades.

[0015]

[Effect of device]

 As described above, according to the present invention, the rail member is composed of the main rail and the sub-rail attached to the main rail, and the sub-rail is provided with the moving distance of the sunshade supported by the sub-rail. Since the rails are formed to have substantially the same length, the raw material of the rail can be saved and the weight of the vehicle body can be reduced.
