JP7834601B2 - Side visor mounting structure and side visor - Google Patents

Description

This invention relates to a mounting structure for a side visor and to a side visor itself.

Conventionally, various mounting structures are known for attaching side visors to automobile window frames, considering various factors such as mounting stability. For example, Patent Document 1 discloses a bracket for attaching a side visor to a window frame, in which a sheet metal with a non-circular hole is inserted into a sheet metal insertion slot formed in a boss engagement portion of the bracket body. Furthermore, it discloses a configuration in which, when a boss provided on the side visor is inserted into the sheet metal hole and the bracket body is rotated around the boss, the edge of the sheet metal hole bites into the boss and is fixed in place.

Japanese Patent Publication No. 2017-088121

However, in the side visor mounting structure of Patent Document 1, the edge of the sheet metal hole bites into the boss, so when an external force is applied to the side visor, the boss may be scraped by the edge of the sheet metal hole, reducing the strength of the protrusion and potentially making the assembly between the side visor and the bracket unstable.
Furthermore, even among vehicles of the same type, there may be dimensional differences of a few millimeters from one vehicle to another, which are acceptable in terms of manufacturing quality. However, even slight dimensional differences in the vehicle body can sometimes hinder the installation of side visors, and the fixing of the side visor to the bracket can reduce the ease of installation. In addition, when the side visor and bracket are fixed together, the side visor may be pulled towards the window frame and deformed according to the dimensional differences when attached to the window frame, potentially impairing the aesthetic appearance.

Therefore, the object of the present invention is to provide a side visor mounting structure and side visor that can prevent a decrease in the strength of the protrusions even when external force is applied to the side visor, have high ease of installation, and do not impair aesthetics.

To achieve the above objective, the invention described in claim 1 is a side visor mounting structure comprising a side visor including a long, strip-shaped flange and a long, strip-shaped visor formed along the flange, a mounting member used when attaching the side visor to the window frame of an automobile, and an adhesive means for attaching the side visor to the window frame, wherein the side visor has a projection that protrudes toward the window frame when attached to the window frame, the base end of the projection has any shape other than a perfect circle when viewed from the window frame side when attached to the automobile, and toward the tip of the projection The mounting member is a plate-shaped member made of an elastic material, equipped with a retaining portion that slopes to widen, with a window frame hooking portion formed at one end for hooking onto the window frame, and an engaging portion formed at the other end for engaging with the side visor, the engaging portion having a hole through which the projection including the retaining portion can be inserted when the mounting member is in a first orientation with respect to the projection, and a hole through which the projection cannot be inserted when the mounting member is in a second orientation with respect to the projection, and the hole has a first hole reference point, with the first hole reference point and the tangent to the first hole reference point The distance between the second hole reference point, which is the point on the inner diameter of the hole where a parallel line segment is tangent, is less than the distance between the first projection reference point and the second projection reference point, which is a point on the outer surface of the projection whose height from the boundary with the canopy where a line segment parallel to the tangent at the first projection reference point is equal to that of the first projection reference point, with the first projection reference point being an arbitrary point on the outer surface of the projection within a range of at least less than or equal to the thickness of the mounting member from the boundary with the canopy. The distance between the first projection reference point and the second projection reference point is greater than or equal to the distance where the distance between the first projection reference point and the second projection reference point is greatest, and less than or equal to the maximum width of the projection including the retaining portion. A second range is formed continuously with respect to the projection, and with the mounting member in the first orientation relative to the projection, the projection is inserted into the hole, and subsequently, by rotation around the projection's projection direction axis, in the second orientation transitioned from the first orientation, both end faces of the projection where the distance between the first projection reference point and the second projection reference point is maximum are located in the second range of the hole, thereby forming a predetermined gap between the projection and the hole, the rotation of the mounting member is suppressed by interference between both end faces and the inner surface of the hole which forms the first range, and the mounting member is prevented from coming out of the hole by the retaining part.
.
The invention described in claim 2 is characterized in that, in addition to the above configuration, the retaining portion tapers and widens toward the tip of the projection.
To achieve the above objective, the invention described in claim 3 is a side visor that includes an elongated strip-shaped flange and a visor formed in an elongated strip shape along the flange, and is attached to the window frame of an automobile via at least a mounting member, wherein the visor has a projection that protrudes toward the window frame when attached to the window frame, the base end of the projection has any shape other than a perfect circle when viewed from the window frame side when attached to the automobile, and has a retaining portion that slopes to widen toward the tip of the projection, and the mounting member is molded from an elastic material. The plate-shaped member has a window frame hook portion formed at one end for hooking onto a window frame, and an engagement portion formed at the other end for engaging with an awning. The engagement portion has a hole through which a projection including a retaining portion can be inserted when the mounting member is in a first orientation relative to the projection, and a hole through which the projection cannot be inserted when the mounting member is in a second orientation relative to the projection. The hole has a first hole reference point, with an arbitrary point in the inner diameter of the hole as the first hole reference point, and a second hole reference point which is a point in the inner diameter of the hole to which a line segment parallel to the tangent to the first hole reference point is tangent. The distance between the projection and the eaves is determined by defining a first projection reference point as an arbitrary point on the outer surface of the projection, within a range of at least less than the thickness of the mounting member from the boundary with the eaves. The first projection reference point is defined as a point on the outer surface of the projection whose height from the boundary with the eaves, where a line segment parallel to the tangent to the first projection reference point is tangent, is equivalent to that of the first projection reference point. The first range is defined as a distance of less than the distance of the distance between the first projection reference point and the second projection reference point, and is defined as a distance of greater than or equal to the distance of the distance between the first projection reference point and the second projection reference point, and less than or equal to the maximum width of the projection including the retaining portion. These two ranges are formed in a continuous manner. The mounting member is positioned in a first orientation relative to the projection, the projection is inserted into the hole, and subsequently, by rotation around the projection's protruding direction, the projection is moved from the first orientation to a second orientation. In this second orientation, the ends of the projection where the distance between the first projection reference point and the second projection reference point is maximized are located within the second range of the hole. As a result, the mounting member maintains a predetermined gap between the projection and the hole. Rotation is suppressed by interference between the ends of the projection and the inner surface of the hole within the first range, and the mounting member is prevented from coming out of the hole by the retaining portion.

According to the invention described in claim 1, after inserting the projection provided on the side visor into the hole of the mounting member which is oriented in the first direction, the projection is prevented from coming off simply by changing the mounting member from the first direction to the second direction, thus making it easy to assemble the side visor and the mounting member. Furthermore, since the assembled state of the side visor and the mounting member is not such that the periphery of the hole is bitten into the projection as in the conventional method, the projection will not be scraped by the mounting member even if an external force is applied to the side visor, thus preventing a decrease in the strength of the projection. Moreover, when the mounting member is oriented in the second direction, the gap between the projection and the hole allows the mounting member to rotate by at least the amount of the gap around the projection's protruding direction, so that even if there is a difference in dimensions of the window frame when attaching the side visor to the window frame, the difference in dimensions can be tolerated, improving the ease of installation, and in the installed state, deformation of the side visor due to the difference in dimensions of the window frame can be reduced, thus maintaining the aesthetic appearance.
According to the invention described in claim 2, when the mounting member is in the second orientation, a gap is formed between the projection and the hole in the direction in which the projection protrudes, so that the mounting member can move by the amount of the gap in the direction in which the projection protrudes. As a result, when attaching the side visor to the window frame, even if there is a difference in dimensions of the window frame, the difference in dimensions can be tolerated in three dimensions, improving the ease of installation, and in the installed state, deformation of the side visor due to the difference in dimensions of the window frame can be further reduced, thus maintaining the aesthetic appearance.

The directions shown in the figures indicate the direction when the visor is mounted on a vehicle.

As shown in Figure 1(a), the side visor 1 is attached to the window frame 2 of the automobile and functions as a sunshade and rain shield. The side visor 1 includes a long, strip-shaped flange portion 3 and a long, strip-shaped canopy body 4 formed along the flange portion 3. As shown in Figures 1(b) and 2(a), the canopy body 4 on the window frame 2 side when attached to the automobile is provided with a projection 5 that is integrally provided with the side visor 1 and protrudes toward the window frame 2.
The side visor 1 is attached to the window frame 2 by assembling the mounting member 6 (described later) to the projection 5, and then using the mounting member 6 and double-sided tape T as an adhesive means.

As shown in Figures 2(a), 4(a) and 4(b), and 5(a) and 5(b), the projection 5 of the side visor 1 has a base end that is roughly diamond-shaped when viewed from the window frame 2 side when the projection 5 is mounted on the vehicle. Furthermore, the projection 5 has retaining portions 7 on both the front and rear sides that are tapered and inclined to widen towards the tip.

The mounting member 6 is a plate-shaped member formed by bending an elastic material such as polyamide resin, polypropylene resin, polyethylene resin, acrylonitrile butadiene styrene resin, or acrylate styrene acrylonitrile resin. As shown in Figures 1(b) and 2(c), a window frame hook portion 8 is formed at one end for hooking onto the window frame 2, and an engagement portion 9 is formed at the other end for engaging with the side visor 1.
As shown in Figures 4(a), (b) and 5(a), (b), the engaging portion 9 is provided with a roughly diamond-shaped hole 10.

Next, we will explain the dimensional relationship between the projection 5 and the hole 10 when viewed from the window frame 2 side in the state of installation on an automobile.
To this end, as shown in Figure 3(a), the first projection reference point A1 is defined as any point on the outer surface of the projection 5 within a range from the boundary with the canopy 4 to the thickness of the mounting member 6. Furthermore, the second projection reference point A2 is defined as the point on the outer surface of the projection 5 to which the line segment AL2, which is parallel to the tangent line AL1 at the first projection reference point A1, is tangent. The distance between the first projection reference point A1 and the second projection reference point A2 is defined as the distance a.
Furthermore, as shown in Figure 3(b), an arbitrary point on the inner diameter of the hole 10 is defined as the first hole reference point B1. In addition, the point on the inner diameter of the hole 10 where the line segment BL2, which is parallel to the tangent line BL1 at the first hole reference point B1, becomes tangent is defined as the second hole reference point B2. The distance between the first hole reference point B1 and the second hole reference point B2 is defined as the distance b.

As shown in Figure 4(a), if the distance between the front end of the front retaining portion 7 on the front side of the projection 5 and the rear end of the rear retaining portion 7 on the rear side is defined as line segment L1, and the distance b when the front end of the hole 10 is defined as the first hole reference point B1 and the rear end as the second hole reference point B2 is defined as line segment D1, then the projection 5 and the hole 10 are formed such that line segment L1 is shorter than line segment D1. In addition, if the distance b when the upper end of the hole 10 is defined as the first hole reference point B1 and the lower end as the second hole reference point B2 is defined as line segment D2, then the projection 5 and the hole 10 are formed such that line segment L1 is longer than line segment D2. On the other hand, if the distance between the upper end and lower end of the projection 5 is defined as line segment L2, then the projection 5 and the hole 10 are formed such that line segment L2 is shorter than line segment D2. By giving the projection 5 and the hole 10 this dimensional relationship, the projection 5 can be inserted into the hole 10 in the first orientation described later, and the projection 5 cannot be inserted into the hole 10 in the second orientation.

Furthermore, if we define the first projection reference point A1 as the point on the front retaining portion 7 of the projection 5 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4, and define the second projection reference point A2 as the point on the outer surface of the projection 5 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4, where the line segment AL2 parallel to the tangent line AL1 at the first projection reference point A1 is tangent, then the distance a between the first projection reference point A1 and the second projection reference point A2 is defined as the point on the rear retaining portion 7 of the projection 5 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4, then the distance a between the first projection reference point A1 and the second projection reference point A2 is defined as the line segment L3. At this time, the line segment L3 is the maximum of any distance a on the outer surface of the projection 5 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4. As shown in Figures 6(b) and 6(c), the hole 10 is formed such that a first range is formed in which at least any interval b excluding line segment D1 is less than the length of line segment L3, and a second range is formed in which any interval b including line segment D2 is greater than or equal to the length of line segment L3 and less than or equal to the length of line segment L1. The periphery of the hole 10 located inside the circle with line segment L3 as its diameter, as shown in Figure 6(b), is the first range in the present invention, and the periphery of the hole 10 located outside the circle with line segment L3 as its diameter, including the front and rear ends of the hole 10 in Figure 6(b), is the second range in the present invention.
Furthermore, the hole 10 is provided in a orientation such that the line segment D1 is parallel to the longitudinal direction of the mounting member 6.

The specific dimensions of the projection 5 are as follows:
The projection width of the projection 5 from the inner surface of the eaves 4 is set within the range of 1 to 10 mm, preferably 4 mm. Line segment L1 is set within the range of 3.5 to 8.5 mm, preferably 5.5 mm. Line segment L2 is set within the range of 2 to 8 mm, preferably 5 mm. Line segment L3 is set within the range of 2.5 to 7.5 mm, preferably 4.5 mm.
Furthermore, the dimensions of the engagement portion 9 of the mounting member 6 are as follows.
The plate thickness of the mounting member 6 is set within the range of 0.5 to 2 mm, preferably 1.5 mm. The line segment D1 of the hole 10 is set within the range of 3 to 13 mm, preferably 8 mm. The line segment D2 is set within the range of 3 to 8 mm, preferably 5 mm.

Furthermore, as shown in Figure 2(b), the projection 5 is molded so that the tip of the projection 5 has a dome shape in the cross-sectional shape defined by the central vertical cross-sectional line, i.e., the line segment L2, when it is mounted on the automobile.
By giving the tip a tapered shape, insertion of the projection 5 into the hole 10 of the mounting member 6 can be started even if the alignment is ambiguous, thus making insertion easier.

Next, we will explain how to attach the side visor 1 to the window frame 2.
First, the side visor 1 and the mounting member 6 are assembled. As shown in Figure 4(a), the projection 5 is inserted from the outside of the mounting member 6 toward the window frame side into the hole 10 drilled in the engaging portion 9 of the mounting member 6. At this time, the mounting member 6 is oriented so that the line segment D1 of the hole 10 is parallel to the line segment L1. This orientation is the first orientation in this embodiment. In Figure 4 of the embodiment, the orientation in which the window frame hook portion 8 is located behind the engaging portion 9 is shown as the first orientation, but the orientation in which the window frame hook portion 8 is located in front of the engaging portion 9 may also be considered the first orientation. That is, the orientation in which the mounting member 6 shown in Figure 4 is rotated 180 degrees along the inner surface of the canopy 4 of the side visor 1 with the projection direction of the projection 5 as the axis may also be considered the first orientation.

Next, with the projection 5 still inserted through the hole 10 of the mounting member 6 in the first orientation, the mounting member 6 is rotated 90 degrees along the inner surface of the canopy 4 of the side visor 1, with the projection 5 as the axis, so that the window frame hook portion 8 is above the engagement portion 9. During the rotation, because the mounting member 6 is made of an elastic material, the hole 10 is pushed open by the outer surface of the projection 5 within the first range. Subsequently, as the rotation moves to the second range, a gap is formed between the projection 5 and the hole 10, as shown in Figures 5(a) and (b), and the first range of the hole 10 that was pushed open returns to its original state.
As described above, the mounting member 6 engages with the side visor 1 and is assembled as shown in Figure 6(a). Therefore, the side visor 1 and the mounting member 6 can be easily assembled simply by inserting the projection 5 through the hole 10 of the mounting member 6 in the first orientation and changing the mounting member 6 from the first orientation to the second orientation.

When the mounting member 6 is in the second orientation, as described above, line segment D2 is longer than line segment L3. Therefore, as shown in Figure 5(b), a gap is formed between the projection 5 and the hole 10 in the direction of projection 5's protrusion and rotation. Consequently, the gap between projection 5 and hole 10 allows the mounting member 6 to rotate by the amount of the gap around the projection direction of projection 5 and to move by the amount of the gap in the projection direction. This allows for three-dimensional tolerance of dimensional differences in the vehicle body when attaching the side visor 1, thereby improving the ease of installation.

After assembling the side visor 1 and the mounting member 6, the window frame hook portion 8 of the mounting member 6 is hooked onto the window frame 2, and the side visor 1 is fixed to the window frame 2 using double-sided tape T. In this way, the side visor 1 is attached to the window frame 2.
In this case, since the mounting member 6 does not bite into the projection 5, even if an external force is applied to the side visor 1, the projection 5 will not be scraped by the mounting member 6, thus preventing a decrease in the strength of the projection 5.

The mounting structure of the side visor 1 in the above form includes a side visor 1 including a long, strip-shaped flange portion 3 and a long, strip-shaped visor body 4 formed along the flange portion 3, a mounting member 6 used when attaching the side visor 1 to the window frame 2 of an automobile, and double-sided tape T for attaching the side visor 1 to the window frame 2. The side visor 1 is provided with a projection 5 that protrudes toward the window frame 2 when attached to the window frame 2, the projection 5 has a base end that is substantially diamond-shaped when viewed from the window frame 2 side when attached to an automobile, and a retaining portion 7 that tapers and inclins to widen toward the tip of the projection 5, and the mounting member 6 is The mounting member 6 is a plate-shaped member formed of an elastic material, with a window frame hook portion 8 formed at one end for hooking onto the window frame 2, and an engagement portion 9 formed at the other end for engaging with the side visor 1. The engagement portion 9 has a hole 10 through which the projection 5, including the retaining portion 7, can be inserted when the mounting member 6 is in a first orientation relative to the projection 5, and through which the projection 5 cannot be inserted when the mounting member 6 is in a second orientation relative to the projection 5. The hole 10 is defined as a first hole reference point B1, with the first hole reference point B1 and a line segment parallel to the tangent at the first hole reference point B1 being tangent to the hole 1. The distance b between the second hole reference point B2, which is the point of the inner diameter of 0, is less than the line segment L3 that maximizes the distance a between the first projection reference point A1 and the second projection reference point A2, which is a point on the outer surface of the projection 5 at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4, with the first projection reference point A1 being an arbitrary point at a height equal to the thickness of the mounting member 6 from the boundary with the canopy 4 to which the line segment parallel to the tangent to the first projection reference point A1 is tangent. The distance b between the second projection reference point A2 is less than the line segment L3 that maximizes the distance a between the first projection reference point A1 and the second projection reference point A2, which is a point on the outer surface of the projection 5 at a height equal to the height of the first projection reference point A1 from the boundary with the canopy 4. The second range is formed continuously, and with the mounting member 6 in the first orientation relative to the projection 5, the projection 5 is inserted into the hole 10. Subsequently, rotation around the projection direction axis of the projection 5 results in the second orientation (transitioned from the first orientation). The end faces of the projection 5 where the distance a between the first projection reference point A1 and the second projection reference point A2 is maximum are located within the second range of the hole 10. As a result, the mounting member 6 maintains a predetermined gap between the projection 5 and the hole 10. Rotation is suppressed by interference between these end faces and the inner surface of the hole 10 (which forms the first range), and the retaining portion 7 prevents it from coming out of the hole 10.

With the mounting structure of the side visor 1 configured in this way, after inserting the projection 5 provided on the side visor 1 into the hole 10 of the mounting member 6 which is in the first orientation, the projection 5 is prevented from coming off simply by changing the orientation of the mounting member 6 from the first orientation to the second orientation, thus making it easy to assemble the side visor 1 and the mounting member 6. Furthermore, since the assembled state of the side visor 1 and the mounting member 6 is not such that the periphery of the hole 10 bites into the projection 5 as in the conventional method, the projection 5 will not be worn down by the mounting member 6 even if an external force is applied to the side visor 1, thus preventing a decrease in the strength of the projection 5. Furthermore, when the mounting member 6 is in the second orientation, the gap between the projection 5 and the hole 10 allows the mounting member 6 to rotate by at least the amount of the gap around the projection direction of the projection 5. Therefore, when attaching the side visor 1 to the window frame 2, even if there are dimensional differences in the window frame 2, these differences can be tolerated, improving the ease of installation. Moreover, in the installed state, deformation of the side visor 1 due to dimensional differences in the window frame 2 can be reduced, thus maintaining aesthetic appeal.

Furthermore, the retaining portion 7 tapers and widens toward the tip of the projection 5.
Therefore, when the mounting member 6 is in the second orientation, a gap is formed between the projection 5 and the hole 10 in the direction of projection 5, allowing the mounting member 6 to move by the amount of the gap in the direction of projection 5. As a result, when attaching the side visor 1 to the window frame 2, even if there is a dimensional difference in the window frame 2, the dimensional difference can be tolerated in three dimensions, improving the ease of installation. Furthermore, in the installed state, deformation of the side visor 1 due to the dimensional difference in the window frame 2 can be further reduced, maintaining an aesthetic appearance.

Figure 7(a) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 1, and Figure 7(b) is an explanatory diagram showing the area around the protrusion of the side visor of Modified Example 1 with the mounting member assembled. Figure 8(a) is an explanatory diagram showing the area around the protrusion of the side visor when the mounting member is assembled to the side visor of Modified Example 1 in the second orientation, and Figure 8(b) is an end view of the line E-E in Figure 8(a). Configurations that exhibit the same effects as those shown in Figures 1-5 are denoted by the same reference numerals as in Figures 1-5, and their explanations are omitted. The directions shown in the figures indicate the direction when the component is mounted on an automobile.

As shown in Figures 7(a), (b) and 8(a), (b), the side visor 1a is provided with a projection 5a that, when viewed from the window frame 2 side in the mounted state on the vehicle, has a circular shape with projections on the front and rear. On both the front and rear sides of the cylindrical portion of the projection 5a, there are protrusions that serve as retaining portions 7a, which taper and widen towards the tip of the projection 5a. The retaining portions 7a also function as ribs that reinforce the projection 5a.

The line segment L4 connecting the front end of the front retaining portion 7a of the projection 5a and the rear end of the rear retaining portion 7a of the projection 5a is formed to be shorter than the line segment D1 of the hole 10 of the mounting member 6 and longer than the short line segment D2 of the hole 10. Furthermore, on the outer surface of the projection 5a, the line segment L5 is formed such that, when the distance a between an arbitrary first projection reference point A1 and second projection reference point A2 at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is set to the maximum length, the front end of the front retaining portion 7a at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 and the rear end of the rear retaining portion 7a at a height equal to the plate thickness of the mounting member 6 from the boundary with the canopy 4 are designated as the first projection reference point A1 and the second projection reference point A2, respectively, the line segment L5 is formed to be slightly shorter than the line segment D2 of the hole 10.
On the other hand, the hole portion 10 is formed such that a first range is continuous in which at least any interval b excluding line segment D1 is less than the length of line segment L5, and a second range is continuous in which any interval b including line segment D2 is greater than or equal to the length of line segment L5 and less than or equal to the length of line segment L4.

The assembly of the side visor 1a and the mounting member 6, and the attachment to the window frame 2, are carried out in the same manner as in the above-described embodiment. Therefore, after inserting the projection 5a provided on the side visor 1a into the hole 10 of the mounting member 6 which is in the first orientation, the mounting member 6 is simply rotated to the second orientation to prevent it from coming off, thus making the assembly of the side visor 1a and the mounting member 6 easy. Furthermore, since the assembled state of the side visor 1a and the mounting member 6 does not involve the periphery of the hole 10 biting into the projection 5a as in the conventional design, the projection 5a will not be scraped by the mounting member 6 even if an external force is applied to the side visor 1a, thus preventing a decrease in the strength of the projection 5a.
Furthermore, when the mounting member 6 is in the second orientation, the gap between the projection 5a and the hole 10 allows the mounting member 6 to rotate by the amount of the gap around the projection direction of the projection 5a and move by the amount of the gap in the projection direction of the projection 5a. As a result, when attaching the side visor 1a to the window frame 2, even if there is a dimensional difference in the window frame 2, the dimensional difference can be tolerated in three dimensions, further improving the ease of installation. In addition, when installed, deformation of the side visor 1a due to the dimensional difference in the window frame 2 can be reduced, and the aesthetic appearance can be maintained.

Figure 10(a) is an explanatory diagram showing the area around the protrusion of the side visor when the mounting member is assembled to the side visor of Modified Example 2 in the second orientation, and Figure 10(b) is an end view along line F-F of Figure 10(a). Figure 11 is an end view along line G-G of Figure 10, and is an explanatory diagram showing the movement of the mounting member when attaching the mounting member to the protrusion of Modified Example 2. Configurations that show the same effect as those shown in Figures 1 to 5 are denoted by the same reference numerals as in Figures 1 to 5, and their explanations are omitted. The directions shown in the figures indicate the direction when the component is mounted on an automobile.

As shown in Figures 9(a), (b), 10(a), (b), and 11, the side visor 1b is provided with a projection 5b having a roughly diamond-shaped base end 11 with vertices on the top, bottom, left, and right sides when viewed from the window frame 2 side in the mounted state on the vehicle. Furthermore, an extended portion 12, which is circular when viewed from the window frame 2 side in the mounted state on the vehicle, extends downward from the tip of the base end 11 of the projection 5b, with the upper vertex of the projection 5b as its upper end. The projection 5b also has an inclined surface that tapers and widens towards the tip of the extended portion 12. This inclined surface is the retaining portion 7b in the modified example 2.

The line segment L6 connecting the front and rear ends of the extended portion 12 of the projection 5b is formed to be shorter than the line segment D1 of the hole 10 of the mounting member 6. On the other hand, if the distance between the upper and lower ends of the projection 5 at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is defined as line segment L7, then line segment L7 is formed to be shorter than line segment D2. Furthermore, on the outer surface of the projection 5b, if the distance a between any first projection reference point A1 and second projection reference point A2 at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4 is defined as the front end of the front retaining portion 7b at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4, and the rear end of the rear retaining portion 7b at a height equivalent to the plate thickness of the mounting member 6 from the boundary with the canopy 4, is defined as the first projection reference point A1 and the second projection reference point A2, where the distance a is the maximum length, then line segment L8 is formed to be slightly shorter than the line segment D2 of the hole 10.
On the other hand, the hole portion 10 is formed such that a first range is continuous in which at least any interval b excluding line segment D1 is less than the length of line segment L8, and a second range is continuous in which any interval b including line segment D2 is greater than or equal to the length of line segment L8 and less than or equal to the length of line segment L6.

Next, we will explain how to assemble the side visor 1b and the mounting member 6.
First, the mounting member 6 is positioned so that the line segment D1 of the hole 10 is parallel to the line segment L6. This orientation is the first orientation in the modified example 2. Then, while maintaining the first orientation, as shown in Figure 11, the mounting member 6 is tilted toward the window side and moved to slide upward from below relative to the expanded portion 12 of the projection 5b (arrow A), so that the expanded portion 12 fits into the hole 10.

Next, the mounting member 6 is returned to its original position (arrow B) so that it comes into contact with the inner surface of the canopy 4 of the side visor 1b. Then, as shown in Figure 9(b), the mounting member 6 is rotated 90 degrees along the inner surface of the canopy 4 of the side visor 1b, with the projection direction of the projection 5b as the axis, so that the window frame hook portion 8 is above the engagement portion 9, thus adopting the second orientation. As a result, the mounting member 6 engages with and is assembled to the side visor 1b.
The subsequent attachment to the window frame 2 is carried out in the same manner as in the embodiment described above.

Therefore, after inserting the projection 5b provided on the side visor 1b into the hole 10 of the mounting member 6 which is in the first orientation, the projection 5b is prevented from coming off simply by turning the mounting member 6 to the second orientation, making it easy to assemble the side visor 1b and the mounting member 6. In addition, since the assembled state of the side visor 1b and the mounting member 6 is not such that the periphery of the hole 10 bites into the projection 5b as in the conventional case, the projection 5b will not be worn down by the mounting member 6 even if an external force is applied to the side visor 1b, thus preventing a decrease in the strength of the projection 5b.
Furthermore, when the mounting member 6 is in the second orientation, the gap between the projection 5b and the hole 10 allows the mounting member 6 to rotate by the amount of the gap around the projection direction of the projection 5b and move by the amount of the gap in the projection direction of the projection 5b. As a result, when attaching the side visor 1b to the window frame 2, even if there is a dimensional difference in the window frame 2, the dimensional difference can be tolerated in three dimensions, further improving the ease of installation. In addition, when installed, deformation of the side visor 1b due to the dimensional difference in the window frame 2 can be reduced, and the aesthetic appearance can be maintained.

The present invention has been described above based on illustrated examples, and its technical scope is not limited thereto. For example, although the embodiment describes installation on the window frame of the left front door of an automobile, the mounting structure for the side visor of the present invention is applicable to both the left and right front side visors and the left and right rear side visors.
Furthermore, the projection may be provided integrally with the side visor as described above, or it may be provided as a separate part. Also, the projection may be provided anywhere on the inside of the side visor when it is mounted on the vehicle, and there may be one or multiple projections. Moreover, the shape of the projection can be arbitrarily designed, except for the base end being a perfect circle, as long as the side visor and mounting member can be assembled by changing the orientation of the mounting member from a first orientation to a second orientation. In addition, the projection may be provided with reinforcing means such as ribs, and the ribs may also function as retaining parts.
Furthermore, the inclined shape of the retaining portion may be flat, curved, or a combination of flat and curved surfaces, or it may have irregularities such as protrusions, and three or more retaining portions may be provided as long as they are provided on the outer circumference of the protrusion.
Furthermore, the shape of the base end of the projection and the shape of the extension can be arbitrarily designed, as shown in the modified example 2 above, as long as the mounting member and the side visor can be assembled in such a way that after the mounting member passes through the extension, the extension restricts the mounting member in the first orientation from moving in the direction of projection.
Furthermore, the shape of the hole only needs to be such that a projection including a retaining portion can be inserted in the first orientation, but the projection cannot be inserted in the second orientation, and can be arbitrarily designed as an ellipse, polygon, etc. In addition, means to prevent over-rotation of the mounting member may be provided on at least one of the projection, visor, or mounting member, separate from the hole.
Furthermore, the rotation angle between the first orientation and the second orientation can be arbitrarily set to the optimal angle based on the combination of shapes of the projection, the retaining part, and the hole.
Furthermore, the second orientation only needs to be within the range where a pressing force is generated on the projection by the hole, and it is not necessarily required that the positions of the concave part, such as the apex of the hole, and the convex part, such as the apex of the projection, coincide.
Furthermore, the material of the mounting member can be selected from materials other than resin, as long as it has sufficient rigidity for attaching the side visor to the window frame, as well as elasticity that allows for the expansion and contraction of the hole due to rotation between the first and second orientations. In addition, the entire mounting member may be formed from an elastic material, or only the engaging portion or the periphery of the hole may be molded from an elastic material.
In addition to double-sided tape, adhesives or other similar materials may also be used for attachment.
