[0006] The problem that the invention aims to solve

[0007] However, in the invention disclosed in document 1, the female component rotates and rubs against the roof liner, which can sometimes damage the roof liner. Furthermore, the friction at this time hinders rotation, making the invention disclosed in document 1 difficult to install.

[0008] This invention was made in view of the actual situation, and its object is to provide a sun visor bracket that can prevent damage to the interior surfaces of the vehicle body and is easy to install on the vehicle body. Furthermore, more broadly, the object of this invention is to provide and utilize a comfortable vehicle by improving the convenience of installation components and maintaining the aesthetics of the interior decoration, which has become a common issue.

[0009] Methods for solving problems

[0010] To achieve the above objectives, the sun visor bracket of the present invention comprises a base component and a bracket component. The base component is installed in a body hole formed in the vehicle body, and the bracket component is installed on the base component and supports the sun visor. The sun visor bracket is characterized in that the base component has: a base body portion having a mounting hole for mounting the bracket component; a plurality of legs extending axially around the mounting hole; and an inner guide portion formed on the inner surface of the base body portion. The bracket component has: a bracket body portion exposed inside the vehicle; a shaft portion extending axially from the bracket body portion along the mounting hole and restricting the deformation of the legs; and an outer guide portion formed on the outer surface of the shaft portion. When the legs are inserted into the body hole and the shaft portion is inserted into the mounting hole, while the outer guide portion is along the inner guide portion, the bracket component rotates clockwise relative to the base component, thereby changing to an installation state in which the bracket body portion contacts the vehicle body.

[0011] The sunshade bracket of the present invention is characterized in that the inner guide portion is a protrusion protruding toward the mounting hole, and the outer guide portion is a track extending circumferentially over the shaft portion and inclined toward the direction of extension of the shaft portion.

[0012] The sunshade bracket of the present invention is characterized in that, by reversing the bracket component relative to the base component while the outer guide portion is aligned with the inner guide portion, the main body of the bracket is changed to a released state away from the vehicle body. An inner engaging portion is formed on the inner surface of the base main body, and an outer engaging portion is formed on the outer surface of the shaft portion. In the installed state or the released state, the inner engaging portion engages with the outer engaging portion.

[0013] The sunshade bracket of the present invention is characterized in that the leg and the inner guide are circumferentially adjacent to the mounting hole, and during the process from the released state to the installed state, the shaft passes through the inner surface of the inner guide and is disposed on the inner surface of the leg. In the installed state, the flexure of the leg toward the mounting hole is restricted by the shaft, and the leg is locked at the edge of the body hole.

[0014] The sunshade bracket of the present invention is characterized in that the base body has a pair of limiting portions formed circumferentially spaced apart from the mounting hole, and a rib is formed on the outer surface of the shaft portion. The rib abuts against one of the limiting portions to restrict the bracket component from rotating forward in the installed state, and abuts against the other limiting portion to restrict the bracket component from rotating backward in the released state.

[0015] The sunshade bracket of the present invention is characterized in that the passage through which the rib passes extends axially along the mounting hole on the inner surface of the base body.

[0016] The sunshade bracket of the present invention is characterized in that a flange portion is formed in the base body portion, the flange portion extending in a direction intersecting with the mounting hole and facing the bracket body portion.

[0017] Invention Effects

[0018] To achieve the above objectives, the sun visor bracket of the present invention comprises a base component and a bracket component. The base component is installed in a body hole formed in the vehicle body, and the bracket component is installed on the base component and supports the sun visor. The base component has: a base main body portion having a mounting hole for mounting the bracket component; a plurality of legs extending axially around the mounting hole; and an inner guide portion formed on the inner surface of the base main body portion. The bracket component has: a bracket main body portion exposed inside the vehicle; a shaft portion extending axially from the bracket main body portion along the mounting hole to restrict deformation of the legs; and an outer guide portion formed on the outer surface of the shaft portion. When the legs are inserted into the body hole and the shaft portion is inserted into the mounting hole, the bracket component rotates clockwise relative to the base component while the outer guide portion moves along the inner guide portion, thereby changing to an installation state in which the bracket main body portion contacts the vehicle body. With the base component mounted on the vehicle body and the bracket component integrated with it, when the bracket component rotates clockwise relative to the base component to reach the installed state, the main body of the bracket does not contact the vehicle body during the period before reaching the installed state. At the instant the sun visor bracket reaches the installed state, the main body of the bracket contacts the vehicle body; therefore, there is no friction between the main body of the bracket and the vehicle body during the period before reaching the installed state. This prevents damage to the interior surfaces of the vehicle body. Furthermore, friction does not hinder the rotation of the bracket component, making it easy to install the sun visor bracket onto the vehicle body.

[0019] In the sun visor bracket of the present invention, the inner guide portion is a protrusion protruding toward the mounting hole, and the outer guide portion is a track extending circumferentially along the shaft portion and inclined toward the direction of extension of the shaft portion. By causing the protrusion (inner guide portion) to follow the inclined track (outer guide portion), the bracket component is rotated relative to the base component and inserted more deeply. Therefore, the main body of the bracket reliably approaches the vehicle body, and the sun visor bracket is in the installed state.

[0020] In the sun visor bracket of the present invention, by rotating the bracket component relative to the base component while the outer guide portion moves along the inner guide portion, the main body of the bracket changes to a disengaged state, separating from the vehicle body. An inner engaging portion is formed on the inner surface of the base main body, and an outer engaging portion is formed on the outer surface of the shaft portion. In the installed or disengaged state, the inner engaging portion engages with the outer engaging portion. The engagement of the inner and outer engaging portions secures the installed and disengaged states. Furthermore, the impact during engagement provides the user with a tactile feedback (click). This tactile feedback at the moment of installation or disengagement facilitates the easy installation of the sun visor bracket onto the vehicle body.

[0021] In the sun visor bracket of the present invention, the leg portion and the inner guide portion are circumferentially adjacent to the mounting hole. During the transition from the disengaged state to the installed state, the shaft portion passes through the inner surface of the inner guide portion and is disposed on the inner surface of the leg portion. In the installed state, the deflection of the leg portion toward the mounting hole is restricted by the shaft portion, and the leg portion is locked at the edge of the body hole. That is, since the leg portion and the inner guide portion are adjacent in the rotation direction of the bracket member, when the bracket member rotates forward relative to the base member, the outer guide portion of the shaft portion is guided by the inner guide portion of the leg portion, thereby the shaft portion passes through the inner surface of the inner guide portion and is disposed on the inner surface of the leg portion. Therefore, with the forward rotation of the bracket member, the installation state is reliably changed.

[0022] In the sunshade bracket of the present invention, the base body has a pair of restricting portions formed circumferentially spaced apart from the mounting hole, and ribs are formed on the outer surface of the shaft portion. The ribs abut against one of the restricting portions to restrict forward rotation of the bracket component in the installed state, and abut against the other restricting portion to restrict reverse rotation of the bracket component in the released state. Therefore, excessive forward and reverse rotation of the bracket component relative to the base component can be prevented.

[0023] In the sunshade bracket of the present invention, the passage through which the rib passes extends axially along the mounting hole on the inner surface of the base body. That is, the rib passes through the passage, allowing the bracket component and the base component to fit together in the correct orientation. In other words, if the rib is in an orientation that prevents it from passing through the passage, the bracket component and the base component will not fit together. Therefore, the possibility of the bracket component and the base component being assembled in an incorrect orientation is prevented.

[0024] In the sun visor bracket of the present invention, a flange portion is formed in the base body portion, which extends in a direction intersecting with the mounting hole and faces the bracket body portion. When the sun visor bracket is mounted to the vehicle body hole, the base flange portion abuts against the surface of the edge of the vehicle body hole. Therefore, when the sun visor bracket is changed to the mounted state, the outer peripheral surface of the vehicle body hole is pressed against the base flange portion, and the bracket body portion overlaps the base flange portion. Thus, the situation where the vehicle body is sandwiched between the base component and the bracket component is prevented. Attached Figure Description

[0076] The sun visor bracket of this invention is, for example, a component that supports a sun visor installed in the roof of a vehicle. Hereinafter, the sun visor bracket of this embodiment will be described based on the accompanying drawings. Figure 1 The appearance of the sunshade bracket 10 is shown. Figure 2 The disassembled sunshade bracket 10 is shown. Figure 3 and Figure 4 The sunshade bracket 10 is shown installed on the vehicle body 1.

[0077] like Figure 1 and Figure 2 As shown, the sunshade bracket 10 consists of a base component 11 and a bracket component 40, which are used together. Figure 3 as well as Figure 4 As shown, the base component 11 is mounted on a hole formed in the vehicle body 1. On the other hand, the bracket component 40 is mounted on the base component 11 and protrudes into the vehicle interior to support the sun visor (illustration omitted). The vehicle body 1 has a roof liner 3, which serves as the interior surface, superimposed on the surface of the body body 2, which is a metal sheet. Holes 4 and 5 are formed on the body body 2 and the roof liner 3, respectively (hereinafter, the holes 4 in the body body and 5 in the roof liner are collectively referred to as "body hole 6").

[0078] The base component 11 and the bracket component 40 can rotate relative to each other when the two components 11 and 40 are engaged. As they rotate, the two components 11 and 40 move closer or further apart. Therefore, the sun visor bracket 10 is in the "released state" when the base component 11 is installed in the body hole 6 and the bracket component 40 is removed from the roof liner 3. (Refer to...) Figure 3 The state in which the bracket component 40 is in contact with the roof liner 3 (hereinafter referred to as the "installation state"). (Refer to...) Figure 4 The variation between 。 ) . For example Figure 3 As shown, in the disengaged state, there is a gap between the base component 11 and the roof liner 3. In this state, when the bracket component 40 rotates clockwise (in... Figure 3 When the direction of arrow 60 is indicated, the gap between the base component 11 and the roof liner 3 narrows, and the sun visor bracket 10 changes to an installed state. On the other hand, as... Figure 4 As shown, in the installed state, the bracket component 40 is pressed against the roof liner 3. In this state, when the bracket component 40 is reversed (in... Figure 4 When the direction of arrow 61 is indicated, the gap between the base component 11 and the roof liner 3 increases, and the sunshade bracket 10 changes to the released state.

[0079] It should be noted that the sun visor bracket 10 is installed in the headliner inside the vehicle, and its state changes by rotating the bracket component 40 exposed inside the vehicle. However, for ease of understanding of the illustration and structure, the sun visor bracket 10 shown in the illustration is reversed vertically from its actual usage state, and the base component 11 rotates relative to the bracket component 40. Therefore, in the following description, the direction of insertion into the body hole 6 is defined as Down, and the direction of withdrawal from the body hole 6 is defined as Up (see reference). Figure 3 as well as Figure 4 Additionally, clockwise rotation is the direction in which the base component rotates to the left when viewed from above (see reference). Figure 3 And arrow 62), the reversal is the direction of rotation of the base component to the right when viewed from above (see...). Figure 4 Arrow 63).

[0080] Next, the base component 11 will be described based on the accompanying drawings. Figures 5 to 15 The exterior and interior views of the base component 11 are shown.

[0081] like Figures 5 to 15 As shown, the base component 11 is a component formed in a generally cylindrical or cup shape. The base component 11 has: a base body portion 13, which has a concave mounting hole 12 for mounting bracket component 40; and a plurality of legs 38 that extend axially around the mounting hole 12 to form part of the mounting hole 12.

[0082] The base body 13 includes: a main annular portion 14, which is generally annular; a base flange portion 15, which is formed on the upper part of the main annular portion 14; a receiving portion 16, which is formed on the lower part of the main annular portion 14; a limiting portion 25, which is formed on the lower part of the receiving portion 16; and a positioning step portion 28 and a positioning piece portion 29, which are formed on the outer peripheral surface of the main annular portion 14. Furthermore, the base body 13 has an inner guide portion 30, an inner engaging portion 31, and a passage portion 39 on its inner surface.

[0083] The base flange 15 is composed of a pair of thin, plate-like sheets that run in opposite directions from the upper edge of the main annular portion 14 toward a direction perpendicular to or intersecting with the mounting hole 12. Figure 5 as well as Figure 6 (The middle part extends in the left-right direction). The leg part 38 is a pair of plate-shaped pieces facing each other across the mounting hole 12, extending downward from the lower end of the main body annular part 14. The storage part 16 is composed of a peripheral wall part 17 and a bottom part 21. The peripheral wall part 17 is a pair of plate-shaped pieces facing each other across the mounting hole 12, extending downward in the axial direction of the mounting hole 12 from the lower end of the main body annular part 14 along the inner circumferential surface of the mounting hole 12. The first peripheral wall part 18, which is one of the pair of peripheral wall parts 17, extends in the circumferential direction. On the other hand, the center of the second peripheral wall part 19, which is the other of the pair of peripheral wall parts 17, is cut out, and the limiting parts 25 are formed at both ends of the cut-out part 20. The limiting parts 25 are composed of a pair. One of the pair of limiting parts 25 is a forward rotation limiting part 26, and the other of the pair of limiting parts 25 is a reverse rotation limiting part 27. The legs 38 and the peripheral wall portions 18 and 19 are arranged on a circumference centered on the mounting hole 12, aligned in the circumferential direction, and adjacent to each other with a gap 70 between them. The width of the legs 38 is narrower than the width of the peripheral wall portions 18 and 19 (in other words, the width of the peripheral wall portions 18 and 19 is wider than the width of the legs 38).

[0084] The bottom 21 is generally circular and connects to the circumferential ends of the lower ends of the peripheral wall portions 18 and 19, spanning the mounting hole 12. A first connecting portion 22 extending from a part of the bottom 21 connects to the first peripheral wall portion 18, and a second connecting portion 23 extending from another part of the bottom 21 connects to the vicinity of the reversing limiting portion 27 of the second peripheral wall portion 19. Therefore, the periphery of the bottom 21, except for the first connecting portion 22 and the second connecting portion 23, is a gap 71 communicating with the mounting hole 12. Thus, the bottom 21 is not connected to the leg portion 38. A central protrusion 24 is formed at the center of the bottom 21. The central protrusion 24 is cylindrical or cylindrical and protrudes upward. The positioning step portion 28 is a step extending outward from the leg portion 38 and the outer side of the peripheral wall portions 18 and 19. The positioning plate portion 29 is a thin plate-like piece disposed on the outer side of the second peripheral wall portion 19 and extends downward.

[0085] The inner guide portion 30 is a pair of protrusions facing each other across the mounting hole 12, formed on the inner surface of each peripheral wall portion 18, 19 and protruding toward the mounting hole 12. The inner engaging portion 31 is a groove formed on the inner surface of each peripheral wall portion 18, 19, extending vertically along the axial direction of the mounting hole 12.

[0086] The first inner engaging portions 32 formed in the first peripheral wall portion 18 of the inner engaging portion 31 are configured as a pair. One of the pair of first inner engaging portions 32 is a first inner disengaging engaging portion 33, and the other of the pair of first inner engaging portions 32 is a first inner mounting engaging portion 34. The first inner disengaging engaging portion 33 and the first inner mounting engaging portion 34 are disposed on both sides of the inner guide portion 30 of the first peripheral wall portion 18. Therefore, the first inner disengaging engaging portion 33 is adjacent to the inner guide portion 30 in the circumferential direction, and the inner guide portion 30 is adjacent to the first inner mounting engaging portion 34 in the circumferential direction. In addition, the first inner mounting engaging portion 34 is adjacent to the leg portion 38 in the circumferential direction with a gap 70 between them.

[0087] The second inner engagement portions 35 formed on the second peripheral wall portion 19 in the inner engagement portion 31 are configured as a pair. One of the pair of second inner engagement portions 35 is a second inner release engagement portion 36, and the other of the pair of second inner engagement portions 35 is a second inner mounting engagement portion 37. The second inner release engagement portion 36 and the second inner mounting engagement portion 37 are disposed on both sides of the inner guide portion 30 of the second peripheral wall portion 19. Therefore, the second inner release engagement portion 36 and the inner guide portion 30 are adjacent in the circumferential direction, and the inner guide portion 30 and the second inner mounting engagement portion 37 are adjacent in the circumferential direction. In addition, the second inner mounting engagement portion 37 is adjacent in the circumferential direction to the leg portion 38, separated by a gap 70.

[0088] The passage portion 39 is a groove formed on the inner surface of the second peripheral wall portion 19, extending vertically along the axial direction of the mounting hole 12. The passage portion 39 is adjacent to the second inner release engagement portion 36 on the side opposite to the inner guide portion 30. Therefore, the passage portion 39 is located between the second peripheral wall portion 19 and the leg portion 38.

[0089] Next, the bracket component 40 will be described based on the accompanying drawings. Figures 16 to 26 The diagram shows the exterior and interior of the bracket component 40.

[0090] like Figures 16 to 26 As shown, the bracket component 40 has a bracket body 41 for attaching and detaching the sunshade and a generally cylindrical shaft portion 44 formed at the lower part of the bracket body 41. The bracket body 41 has a bracket flange portion 42 and a hook portion 43 formed at the upper part of the bracket flange portion 42. The bracket flange portion 42 is a thin, generally quadrilateral plate extending laterally. The shaft portion 44 is a pair of plate-shaped pieces that are bent towards each other at intervals and extend downward from the lower end of the bracket body 41. One of the pair of shaft portions 44 is a first shaft portion 45, and the other of the pair of shaft portions 44 is a second shaft portion 46. Each shaft portion 45, 46 has an outer guide portion 47, an outer engaging portion 48, and a rib 56 on its outer surface.

[0091] The outer guide portion 47 is a pair of tracks formed circumferentially in each shaft portion 45, 46. The outer guide portion 47 has an inclined portion 49, a first horizontal portion 50, and a second horizontal portion 57. The inclined portion 49 extends circumferentially and slopes downwards or upwards. The first horizontal portion 50 is connected to the lower part of the inclined portion 49 and extends horizontally circumferentially. The second horizontal portion 57 is connected to the upper part of the inclined portion 49 and extends horizontally circumferentially. The length of the outer guide portion 47 in the circumferential direction is shorter than one-quarter of the circumference when the shaft portion 44 is circular.

[0092] The outer engaging portion 48 is a rib-like protrusion extending vertically along the axial direction, forming a pair for each shaft portion 44. The lower side of the pair of outer engaging portions 48 is the lower outer engaging portion 51, and the upper side of the pair of outer engaging portions 48 is the upper outer engaging portion 52. The outer engaging portions 51 and 52 are arranged on the same straight line along the axial direction.

[0093] The lower outer engaging portion 51 is formed at the front end of the outer engaging piece 54. The outer engaging piece 54 is formed by cutting off a portion of the shaft portion 44. Specifically, a space, namely a window portion 53, communicating with the inner side of the shaft portion 44 is formed between the outer guide portion 47 and the support flange portion 42 in the shaft portion 44. The outer engaging piece 54 extends circumferentially from the circumferential edge of the window portion 53. The base portion 55 of the outer engaging piece 54, which is only connected to the edge of the window portion 53, is connected to the shaft portion 44. The area around the outer engaging piece 54 other than the base portion 55 is formed by a gap 72 in the window portion 53 and is not connected to the shaft portion 44. Therefore, when an external force is applied to the outer engaging piece 54, the outer engaging piece 54 flexes inward toward the shaft portion 44 starting from the base portion 55. The upper outer engaging portion 52 is located above the lower outer engaging portion 51 via the window portion 53.

[0094] Rib 56 is formed in the second shaft portion 46 but not in the first shaft portion 45. Rib 56 protrudes outward and is formed at the lower end of the second shaft portion 46. Rib 56 is located in a position offset in the circumferential direction relative to the outer engaging portion 48 (see reference). Figure 21 ).

[0095] As described above, the bracket component 40 and the base component 11 constitute the structure. Next, the installation sequence, function, and effects of the sunshade bracket 10 will be explained based on the accompanying drawings. Figure 27 The image shows the bracket component 40 and the base component 11 assembled.

[0096] First, the function and effect of the bracket component 40 and the base component 11 during the assembly process will be explained. Next, the function and effect of the bracket component 40 and the base component 11 in the combined state will be explained.

[0097] Before the bracket component 40 and the base component 11 are assembled together, the base component 11 is installed on the vehicle body 1. First, in Figure 3 In this configuration, the storage portion 16 and leg portion 38 of the base component 11 are inserted into the hole 5 of the roof liner. The storage portion 16 and leg portion 38, protruding from the hole 5 of the roof liner, are inserted into the hole 4 of the body body, while the roof liner 3 overlaps with the body body 2. The body hole 6 is not a perfect circle, but rather a portion of its circumference protrudes outwards. The positioning piece portion 29 of the base component 11 passes through this protruding portion, thus the posture in which the base component 11 can pass through the body hole 6 is predetermined. Therefore, it is possible to prevent the base component 11 from being installed in the body hole 6 in an incorrect posture. Furthermore, the base component 11 is positioned by the positioning step portion 28 abutting against the outer peripheral surface of the hole 4 in the body body.

[0098] With the storage portion 16 and leg portion 38 of the base component 11 installed in the body hole 6 and the headliner 3 overlapping the body body 2, the bracket component 40 is installed on the base component 11. The base component 11 has a base flange portion 15 that abuts against the outer peripheral surface of the hole 5 of the headliner and faces the bracket flange portion 42 of the bracket component 40. When the base component 11 is rotated clockwise in the direction of arrow 62 and the sun visor bracket 10 changes from the disengaged state to the installed state, the outer peripheral surface of the hole 5 of the headliner presses against the base flange portion 15, and the bracket flange portion 42 overlaps the base flange portion 15. Therefore, it is possible to prevent the headliner 3 from being sandwiched between the base component 11 and the bracket component 40.

[0099] like Figure 27 As shown, when the bracket component 40 is installed on the base component 11, the shaft portion 44 of the bracket component 40 is installed in the mounting hole 12 of the base component 11 with the rib 56 of the bracket component 40 aligned vertically with the passage portion 39 of the base component 11. If the shaft portion 44 is inserted into the mounting hole 12 until the rib 56 passes through the passage portion 39, the bracket component 40 and the base component 11 are joined together. The sunshade bracket 10 is in a disengaged state immediately after joining together. The rib 56 passes through the passage portion 39, thus allowing the bracket component 40 and the base component 11 to join together in the correct posture, thereby preventing the bracket component 40 and the base component 11 from being assembled in an incorrect posture.

[0100] Next, the function and effect of the bracket component and the base component when they are combined will be explained. Figures 28 to 41 The image shows the state in which the support component 40 and the base component 11 are assembled. Figures 28 to 34 Indicates the state of being released. Figures 35 to 41 Indicates the installation status. Figures 42 to 51 The image shows a cross-section of the bracket component 40 and the base component 11 in their combined state.

[0101] <The effect and function of the relative rotation between the support component 40 and the base component 11>

[0102] exist Figures 28 to 34 In the released state shown, when the base component 11 rotates clockwise, the sunshade bracket 10 becomes... Figures 35 to 41 The installation state is shown. In the disengaged state, the base flange 15 of the base component 11 separates from the bracket flange 42 of the bracket component 40, creating a gap between the base flange 15 and the bracket flange 42. In the disengaged state, when the base component 11 rotates clockwise, the two components 11 and 40 gradually move towards each other while rotating clockwise, filling the gap between the flanges 15 and 42. On the other hand, in Figures 35 to 41 In the installation state shown, when the base component 11 is reversed, it becomes Figures 28 to 34The diagram shows the disengaged state. In the installed state, the base flange 15 and the bracket flange 42 are close together, with no gap between them. In the installed state, when the base component 11 is reversed, the two components 11 and 40 gradually move towards separation while reversing, creating a gap between the flanges 15 and 42.

[0103] When the base component 11 rotates clockwise, the gap between the bracket flange portion 42 of the bracket component 40 and the base flange portion 15 of the base component 11 gradually narrows during the transition of the sun visor bracket 10 from the disengaged state to the installed state. Therefore, during this transition, the bracket flange portion 42 does not contact the roof liner 3 (see reference). Figure 3 and Figure 4 When the sun visor bracket 10 is in the installed state, the bracket flange 42 contacts the headliner 3, so there is no friction between the bracket flange 42 and the headliner 3 during the transition from the deactivated state to the installed state. Therefore, damage to the headliner 3 can be prevented. In addition, the friction does not hinder the rotation of the bracket component 40, so the sun visor bracket 10 is easy to install on the vehicle body 1.

[0104] <The function and effect of the shaft portion 44 of the support component 40 and the peripheral wall portion 17 of the base component 11>

[0105] like Figure 42 As shown, in the disengaged state, the lower portions of each shaft portion 45, 46 of the support component 40 approach the central protrusion 24 of the base component 11. Each shaft portion 45, 46 is opposite to the inner surface of each peripheral wall portion 18, 19 of the base component 11. In the disengaged state, when the base component 11 rotates clockwise, as... Figure 43 As shown, the central protrusion 24 is inserted into the inner side of each shaft portion 45, 46, and each shaft portion 45, 46 is disposed on the inner surface of each leg portion 38 along the circumferential direction through the inner surface of each peripheral wall portion 18, 19. Since the deflection of each leg portion 38 toward the mounting hole 12 is restricted by each shaft portion 45, 46, each leg portion 38 is locked at the edge of the body hole 6 (see reference). Figure 4 The sunshade bracket 10 will not detach from the body hole 6.

[0106] <Function and effect of the outer guide portion 47 of the support component 40 and the inner guide portion 30 of the base component 11>

[0107] like Figure 44 as well as Figure 45 As shown, in the released state, each inner guide portion 30 engages with the first horizontal portion 50 of each outer guide portion 47. In the released state, when the base component 11 rotates clockwise, as... Figure 46 and Figure 47As shown, each outer guide portion 47, while engaged with each inner guide portion 30, moves along each inner guide portion 30 from the first horizontal portion 50 to the second horizontal portion 57 via the inclined portion 49. The inclined portion 49 extends circumferentially and is inclined vertically, thus allowing each shaft portion 44 of the bracket member 40 to be deeply inserted into the mounting hole 12 of the base member 11, reliably achieving the installed state. Similarly, in the installed state, when the base member 11 is reversed, each outer guide portion 47, while engaged with each inner guide portion 30, moves along each inner guide portion 30 from the second horizontal portion 57 to the first horizontal portion 50 via the inclined portion 49. Simultaneously, each shaft portion 44 is gradually pulled out of the mounting hole 12, reliably achieving the released state. Furthermore, the length of the outer guide portion 47 in the circumferential direction is shorter than one-quarter of the circumference when the shaft portion 44 of the base member 11 is circular, therefore the rotation angle of the base member 11 during clockwise or counterclockwise rotation is less than 90 degrees. Therefore, the user's burden is reduced when the base component 11 is rotated forward or backward.

[0108] <The function and effect of the outer engaging portion 48 of the bracket component 40 and the inner engaging portion 31 of the base component 11>

[0109] like Figure 48 and Figure 49 As shown, in the released state, each lower outer engagement portion 51 of the bracket component 40 engages with the first inner release engagement portion 33 and the second inner release engagement portion 36 of the base component 11, respectively. Each lower outer engagement portion 51 is formed at the front end of each outer engagement piece 54 formed in the window portion 53 of the shaft portion 44 and elastically deformable. Therefore, in the released state, the base component 11 rotates clockwise (in... Figure 49 (The middle is right-handed), thereby pressing each outer engaging piece 54 from the peripheral wall portions 18 and 19 of the base component 11 and bending it towards the inner side of the shaft portion 44 via each lower outer engaging portion 51. At the same time, the lower outer engaging portions 51 disengage from each inner disengaging engaging portion 33 and 36, sliding on each peripheral wall portion 18 and 19 while shifting in the circumferential direction, engaging with the first inner mounting engaging portion 34 and the second inner mounting engaging portion 37 respectively. Thus, as Figure 50 as well as Figure 51 As shown, it has entered the installation state.

[0110] Similarly, in Figure 50 and Figure 51 In the installation state shown, the base component 11 is reversed (in... Figure 51 (Rotating to the left), each lower outer locking part 51 disengages from each inner mounting locking part 34, 37, and slides along the circumferential direction on each peripheral wall part 18, 19, respectively, engaging with each inner unlocking locking part 33, 36. Thus, as... Figure 48 as well as Figure 49As shown, it enters the disengaged state. The inner engaging portion 31 engages with the outer engaging portion 48, securely maintaining the installed or disengaged state. Furthermore, the impact during engagement provides the user with a tactile feedback (click). This tactile feedback at the moment of entering the installed or disengaged state facilitates easy installation of the sun visor bracket 10 onto the vehicle body 1.

[0111] <The function and effect of the rib 56 of the support component 40 and the limiting part 25 of the base component 11>

[0112] like Figure 34 As shown, in the released state, rib 56 is disposed in the reversing limiting part 27 of the limiting part 25. By abutting against the reversing limiting part 27, the reversal of the base member 11 is restricted (in...). Figure 34 (rotating to the left). Therefore, it prevents the base component 11 from excessively reversing relative to the support component 40. On the other hand, as Figure 41 As shown, in the installed state, rib 56 is disposed in the forward rotation limiting part 26 of the limiting part 25, and rib 56 abuts against the forward rotation limiting part 26, thereby limiting the forward rotation of the base component 11 (in Figure 41 (The center is right-handed). Therefore, it prevents the base component 11 from rotating excessively clockwise relative to the support component 40.

[0113] In other embodiments of the invention, the outer guide portion of the support component is a protrusion that protrudes outward, and the inner guide portion of the base component is a track.

[0114] In another embodiment, the inner engaging portion is a rib-like protrusion extending axially up and down on the inner surface of each peripheral wall portion, and the outer engaging portion is a groove extending axially up and down on the outer surface of each shaft portion.

[0115] In other embodiments, the base component has a single inner engaging portion, and the bracket component has a pair of outer engaging portions. In this embodiment, in the installed state, the inner engaging portion engages with an outer mounting engaging portion that is one of the outer engaging portions, and in the released state, the inner engaging portion engages with an outer release engaging portion that is the other of the outer engaging portions.

[0116] In another embodiment, ribs are formed on the base member and limiting portions are formed on the support member.

[0117] In another embodiment, ribs are formed on the base component and passages are formed on the support component.

[0118] Other embodiments do not have a base flange.

[0119] In another embodiment, in the installed state, the bracket component is pulled out vertically relative to the base component, thereby becoming the released state.

[0120] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described above. Furthermore, various design changes can be made to the present invention without departing from the scope of the claims. Vehicles incorporating embodiments of the present invention include, for example, trains, ships, and airplanes.
