Description

  The present invention relates to a sunshade, and more particularly to a sunshade component for an automobile.

As shown in FIG. 1, a conventional automobile sunshade 1 incorporated in an automobile sunroof (not shown) includes a pull-back unit 11, a set of rails 12, and a screen 13. The screen 13 can be operated between a wound state in which the screen 13 is wound around the pull-back unit 11 and an extended state in which the screen 13 is advanced along a set of rails 12. In order to prevent the screen 13 from detaching from the rail 12 due to the sudden strong wind force passing through the sunroof or the impact of a person in the car, a number of ball-shaped members 14 are arranged on opposite side edges of the screen 13. Installed on. The structure of the ball-shaped member 14 is larger than the sliding opening 120 of the rail 12, thereby preventing the screen 13 from coming off the rail 12. However, the arrangement in which a plurality of ball-shaped members 14 are provided on the screen 13 makes it difficult to assemble and manufacture the sunshade 1. FIGS. 2 and 3 show other conventional automotive sunshades that employ a different structure to prevent the screen 21 from detaching from the rails 22. In this arrangement, inclined elastic strips 23 are provided on opposite side edges of the screen 21, respectively. In order to prevent the screen 21 from coming off the rail 22, the screen 21 is elastically caught on the upper and lower wall portions of the rail 22 by inserting the strips 23 into the recesses 220 of the rail 22. However, since the strip 23 is formed as a flat sheet-like element, when a force is applied to the strip 23 toward the opposite rail 22 as a result of the screen 21 being pulled, the strip 23 Transforms easily. If this happens, the screen 21 can easily disengage from the recess 220 of the rail 22.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 4, 5, and 6, the preferred embodiment of the sunshade component according to the present invention is mounted on the sunroof 900 of the automobile 9 to selectively cover the sunroof 900.

  The sunshade component includes a roller 3, a set of rails 4, a screen unit 5, and a loop 6. The roller 3 is always urged to rotate in the winding direction. Since the structure of the roller 3 is known to those skilled in the art and is not the main feature of the present invention, detailed description is omitted for the sake of brevity.

  Further, referring to FIG. 7, each rail 4 has an upper wall 42 and a lower wall 43 that joints with the upper wall 42 to form a recess 40 and an opening 401. The opening 401 is in spatial communication with the recess 40 and faces the other rail 4.

  The screen unit 5 includes a screen 52 and a set of platform elements 51. The screen 52 has opposing peripheral edges, and the screen 52 can be operated between a wound state in which the screen 52 is wound around the roller 3 and an extended state in which the screen 52 is fed from the roller 3. Each pedestal element 51 is slidably disposed in the recess 40 of each rail 4, is disposed at one of the peripheral edges of the screen 52, and is in contact with the lower wall 43 of each rail 4. 511 and a second arch portion 512 freely extending from the first arch portion 511. As shown in FIGS. 7 and 8, the first portion 511 normally forms an arch downward, and in an unusual time, the first portion 511 forms an arch upward due to excessive pulling of the screen 52. . The second portion 512 is in contact with one lower wall 43 of each rail 4 during normal times, and is in contact with the upper wall of each rail 4 during non-normal times.

  The lower wall 43 of each rail 4 includes a connecting portion 431, a horizontal portion 432, and a limiting portion 433. The connecting portion 431 is fixed to the bottom surface of the upper wall 42. The horizontal portion 432 extends from the connection portion 431 in the direction of the opposing rail of the rails 4 and is disposed away from the upper wall 42. The limiting portion 433 faces the connecting portion 431 and extends from the horizontal portion 432 toward the bottom surface of the upper wall 42, and the limiting surface 434 faces the connecting portion 431. The connecting portion 431, the horizontal portion 432, the limiting portion 433 and the upper wall 42 jointly form a recess 40. The opening 401 is formed between the upper end portion of the limiting portion 433 and the upper wall 42 in order to extend the peripheral edge portion of the screen 52 to the concave portion 40. The first portion 511 of each platform element 51 is in contact with the limiting surface 434 of the limiting portion 433. Each pedestal element 51 further includes a third portion 513 that extends freely from the first portion 511 and is separated from the second portion in the vertical direction. The third portion 513 is directed upward so as to be elastically pressed against the bottom surface of the screen 52, and the screen 52 is elastically distorted upward from the first portion 511.

  In a preferred embodiment, each platform element 51 is formed of a plastic material. In a further preferred embodiment, each platform element 51 and the peripheral edge of the screen 52 are both fused together by heat.

  In a preferred embodiment, each rail 4 further has a fixed wall 41 fixed to the upper wall 42. The fixed wall 41 can be used to attach a sunshade component to the sunroof 900 of the automobile 9.

  In order to provide the base element 51 having sufficient strength so that the base element 51 can be flexibly distorted inside the recess 40, it is preferable to perform the following steps when manufacturing the screen unit 5. . The first step is to obtain a piece of plastic sheet. Second, two plastic strips are obtained, each folded in two. Third, the opposing peripheral edges of the plastic sheet are individually sandwiched with folded plastic strips. Finally, selected portions of the plastic strip are fused to the plastic sheet with heat. The region where the plastic strip and the plastic sheet are thermally fused is curved downward so as to form the first portion 511 of the base element 51. Regions of the plastic strip that are not thermally fused to the plastic sheet form a second portion 512 and a third portion 513.

  In one embodiment, each platform element 51 bonds three plastic layers together to increase the strength of the platform elements 51 so that the platform elements 51 can flex flexibly within the recess 40. Formed. In addition, the manufacturing method of the screen unit 5 is not restricted to the said process.

  The loop 6 is fixedly provided at one end of the screen 52 so that the screen unit 5 is pulled and fastened to a hanger (not shown) disposed in a passenger compartment of the automobile. In such a state, the screen unit 5 is extended so as to cover the sunroof 900 as shown in FIG. The operation of the sunshade component will be described with reference to FIGS. In the extended state, the screen unit 5 advances along the rail 4 so as to cover the sunroof 900. If the screen unit 5 receives a deflection force as a result of the wind force passing through the sunroof 900 or the impact of the passenger, the screen 52 moves upward or downward to pull the platform element 51. Assuming that such a bending force is not strong, since the first portion 511 is curved downward, the first portion 511 is pressed toward the limiting surface 434 of the limiting portion 433 when being pulled, and at the same time The second part 512 pushes the connection part 431 of the lower wall 43. In addition, due to the structure and shape of the first portion 511, the first portion 511 does not easily bend upward.

  As shown in FIG. 8, if such a bending force acting on the screen 52 becomes stronger, the platform element 51 shifts to an abnormal state. That is, if the screen 52 pulls the platform element 51 with a size exceeding a predetermined threshold value, the first portion 511 is elastically bent upward. If this happens, the second portion 512 is moved against the bottom surface of the top wall 42. In this state, as shown in FIG. 8, the base element 51 is prevented from being removed from the recess 40.

  Although the present invention has been described in connection with the most practical and preferred embodiments, the present invention is not limited to the disclosed embodiments and variations equivalent to all such modifications. Is understood to mean a wide variety of variations that fall within the spirit and scope of the broadest interpretation.
