Description

  The present invention relates to a technique for mounting a vehicle sun visor to a vehicle interior ceiling surface.

  The vehicle sun visor is mounted on the ceiling surface of the passenger compartment via a substantially L-shaped support shaft, and is placed along the ceiling surface of the passenger compartment by rotating around the horizontal axis of the support shaft. The arrangement position is changed between the storage position to be placed and the use position (light-shielding position) placed along the windshield. The sun visor main body is provided with a cylindrical case into which the horizontal shaft portion of the support shaft is inserted, and the spring is disposed while urging the horizontal shaft portion of the support shaft in the radial direction by a spring member disposed in the cylindrical case. It is configured to receive (support) the horizontal shaft portion on the case inner wall surface on the side opposite to the member. As a result, the sun visor body is connected to the support shaft so as to be relatively rotatable about the long axis of the horizontal shaft portion. According to such a configuration, the urging force of the spring member can be stably applied to the horizontal shaft portion of the support shaft. A vehicle sun visor having such a configuration is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-147148 (Patent Document 1).

In the above-described conventional vehicle sun visor, the case inner wall surface that receives the outer surface of the horizontal shaft portion is formed in a semicircular arc shape corresponding to the outer surface of the horizontal shaft portion having a circular cross section on the side opposite to the spring member. That is, the horizontal shaft portion is configured to be held by being pressed against the inner wall surface of the case by the spring member in a state where the outer surface is engaged (fitted) with the semicircular arc inner wall surface. However, in such a configuration, it is difficult to form the cylindrical case with high accuracy such that the inner wall surface of the semicircular arc shape coincides with the outer surface of the horizontal shaft portion. If the engagement is tight, when the sun visor body is rotated between the retracted position and the use position, the smoothness of the rotating operation may be reduced or abnormal noise may be generated. If the sun visor body is loose, when the sun visor body is rotated between the retracted position and the use position, a shaft runout (a phenomenon in which the rotating shaft is displaced in a direction intersecting the major axis direction) occurs, and the sun visor body Rotating motion becomes unstable. That is, the conventional vehicle sun visor still has room for improvement in terms of operability.
JP-A-10-147148

  In view of the above, an object of the present invention is to provide a technique that contributes to improvement in operability when a sun visor body is rotated around a spindle in a vehicle sun visor.

  In order to achieve the above object, preferred embodiments of the vehicle sun visor according to the present invention include a sun visor main body, a support shaft for attaching the sun visor main body to the vehicle body, and a relative rotation with respect to the sun visor main body as a support shaft by mounting the sun visor main body. And a bearing portion that is freely connected, and the bearing portion is capable of relative rotation around the major axis of the support shaft with respect to the support shaft. The “support shaft” in the present invention is typically formed in an L shape, but preferably includes a T-shaped support shaft. The bearing portion has an accommodation space in which the support shaft is accommodated, and an elastic body that urges the support shaft arranged in the accommodation space in the radial direction of the support shaft is arranged in the accommodation space. The “elastic body” in the present invention typically corresponds to a spring, but preferably includes rubber. The bearing portion holds the arc-shaped cross-section formed by the arc-shaped portion of a part or the whole in the circumferential direction at a predetermined axial direction of the support shaft with only two contact points on the inner wall portion on the opposite side of the elastic body. It is supposed to be configured. In the present invention, the “arc-shaped cross-section” refers to either the aspect in which the arc-shaped cross-section is formed over the whole or the part in which the arc-shaped cross-section is formed in the entire major axis direction of the support shaft. Are also preferably included. In the present invention, “part or all of the circumferential direction is formed by the arc-shaped portion” means an aspect in which a notch is provided in a part of the circumferential direction, or an aspect in which the arc is continuous over the entire circumferential direction. Corresponds to this. The “contact point” in the present invention includes not only a contact mode by point contact but also a contact mode by line contact in the major axis direction of the support shaft. In addition, regarding the cross section of the bearing portion and the support shaft, not only point contact in geometry but also an aspect in which the bearing portion and the support shaft are in contact with each other with a certain arcuate length (width) in the circumferential direction is referred to as “contact point” in the present invention. Is included.

  According to the preferred embodiment of the vehicle sun visor according to the present invention, the support shaft disposed in the housing space of the bearing portion is urged in the radial direction by the elastic body and is supported at the space inner wall portion on the opposite side to the elastic body. By adopting a configuration in which the arcuate cross-section of the shaft is held by only two contact points, the bearing portion can hold the support shaft in a state where the center of the bearing portion and the center of the support shaft coincide with each other. Here, the “center of the bearing portion” refers to a point where an action line of the urging force by the elastic body and a straight line (normal line) perpendicular to the tangent line of each of the two contact points intersect. That is, according to the present invention, the shaft runout when the support shaft and the bearing portion rotate relative to each other is prevented, and the sun visor main body is stably and smoothly rotated around the long axis of the support shaft. be able to. Further, according to the present invention, it is not necessary to form a highly accurate space inner wall surface corresponding to the outer shape of the support shaft, and it is easy to make.

  Moreover, according to the further form of the vehicle sun visor according to the present invention, the two contact points on the inner wall portion of the space are configured to be opposite to each other across the line of action of the urging force of the elastic body acting on the support shaft. Is done. According to the present invention, by setting as described above, it is possible to construct a bearing structure in which shaft runout does not occur when the bearing portion rotates relative to the support shaft. In this case, it is preferable that the angles formed by the tangent lines of the two contact points and the action line of the urging force by the elastic body are set to be equal to each other, that is, the two contact points are set at symmetrical positions with respect to the urging force action line. However, it does not have to be a symmetrical position.

  Moreover, according to the further form of the vehicle sun visor which concerns on this invention, a spindle has a notch in the predetermined area | region of the circumferential direction in the area | regions other than a predetermined place of an axial direction, and the area | region which contact | abuts with an elastic body. Then, when the sun visor body is rotated around the long axis direction of the support shaft together with the bearing portion, the sun visor body is stopped at a predetermined rotation position by engaging the notch with the elastic body. Note that the “predetermined rotation position” in the present invention typically corresponds to a storage position where the sun visor body is placed along the ceiling of the passenger compartment when not in use. ADVANTAGE OF THE INVENTION According to this invention, a sun visor main body can be stopped in a predetermined rotation position, ensuring the stable and smooth rotation operation | movement of a sun visor main body.

  ADVANTAGE OF THE INVENTION According to this invention, the technique which contributes to the improvement of operativity at the time of rotating operation of a sun visor main body to the surroundings of a spindle was provided in the sun visor for vehicles.

  Hereinafter, a vehicle sun visor according to an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows an overall configuration of a vehicle sun visor according to the present embodiment. As shown in FIG. 1, a vehicle sun visor 101 according to the present embodiment is generally viewed as a sun visor main body 103 constituting the outer shape of the sun visor 101 and a circular cross-section support for mounting the sun visor main body 103 on the vehicle. The shaft 105 and the mounting bracket 107 are mainly configured. The support shaft 105 is formed in a substantially L shape having a vertical axis portion 105 a extending in a substantially vertical direction and a horizontal axis portion 105 b extending in a substantially horizontal direction, and the horizontal shaft portion 105 b is one of the upper edges of the sun visor body 103. It is attached to the corner part of this so that relative rotation is possible. The longitudinal axis portion 105 a of the support shaft 105 is rotatably attached to the front corner portion of the passenger compartment ceiling surface via the mounting bracket 107. The details of the mounting structure of the support shaft 105 to the sun visor body 103 will be described later. For convenience of explanation, the major axis direction of the horizontal axis portion 105b is referred to as the left-right direction, the major axis direction of the vertical axis portion is referred to as the vertical direction, and the horizontal direction intersecting the major axis direction of the horizontal axis portion 105b is referred to as the front-back direction.

  The sun visor main body 103 is rotated around the long axis of the horizontal shaft portion 105b of the support shaft 105, so that the sun visor main body 103 is placed along the ceiling surface of the passenger compartment, and the use position is placed along the windshield. The arrangement position can be changed between (light shielding position). Further, the sun visor main body 103 can change the arrangement position between the front position and the side position along the side glass by rotating around the long axis of the vertical axis portion 105a. The sun visor body 103 has a support shaft 109 on the free end side of the upper edge portion. The support shaft 109 is held by a hook attached to the ceiling surface of the passenger compartment. This stabilizes the rotation operation of the sun visor body 103 when the arrangement position of the sun visor 101 is changed from the storage position to the use position or from the use position to the storage position.

  The sun visor main body 103 is configured so as to form a hollow shell structure by joining two half-divided main body constituent members 103A and 103B opposite to each other in the front-rear direction (see cross-sectional views of FIGS. 2 to 7). ), And the surfaces of the main body constituting members 103A and 103B are covered with a skin as necessary.

  Next, the bearing structure (connection structure) of the support shaft 105 with respect to the sun visor body 103 will be described with reference to FIGS. 2 to 7 show cross-sectional structures based on the cross-section indicating lines in FIG. FIG. 8 shows the components constituting the bearing structure in an exploded state, and FIG. 9 shows the assembled state as a perspective view. Further, FIGS. 10 to 13 show steps of assembling the constituent members constituting the bearing structure with respect to the sun visor body 103 in a stepwise manner.

  As shown in FIGS. 8 and 9, the bearing structure of the support shaft 105 with respect to the sun visor main body 103 according to the present embodiment includes a cylindrical case 117 formed in a metal cylinder and an internal space of the cylindrical case 117. The spring member 118 disposed at 117a and a fixing member 119 for fixing the cylindrical case 117 to the sun visor body 103 are mainly configured. The cylindrical case 117 corresponds to the “bearing portion” in the present invention, the internal space 117a corresponds to the “accommodating space” in the present invention, and the spring member 118 corresponds to the “elastic body” in the present invention. The spring member 118 is appropriately fixed to the lower part of the case inner wall of the cylindrical case 117 by fastening means.

  The horizontal shaft portion 105b of the support shaft 105 is configured as a stepped shaft having a circular cross section having a large diameter portion 105f in the middle region in the long axis direction, and is inserted into the internal space 117a from one opening portion of the cylindrical case 117. The The horizontal shaft portion 105b is urged in the radial direction by the spring member 118 on the outer surface of the large-diameter portion 105f and is received by the case inner wall upper portion 117b opposite to the spring member 118. That is, the cylindrical case 117 is a case inner wall opposite to the spring member 118 while causing a biasing force (elastic force) by the spring member 118 to act on the horizontal shaft portion 105b inserted in the internal space 117a in the radial direction. By receiving (supporting) the horizontal shaft portion 105b by the upper portion 117b, the large-diameter portion 105f of the horizontal shaft portion 105b is gripped so as to be relatively rotatable. This state is shown in FIG. 3 and FIG. The case inner wall upper portion 117b corresponds to the “space inner wall portion” in the present invention.

  As shown in FIGS. 8 and 9, the spring member 118 includes a long and narrow elastic plate portion 118 a and first and second elastic members that extend upward from both longitudinal ends of the substrate portion 118 a in a substantially S shape. The bending portion 118b is integrally formed, and a predetermined urging force is applied to the horizontal shaft portion 105b by the elastic bending of the first and second elastic bending portions 118b. The spring member 118 is disposed so that the first and second elastic deflecting portions 118b are in contact with two locations in the major axis direction of the large-diameter portion 105f of the horizontal shaft portion 105b. The first and second elastic deflecting portions 118b are applied to the outer peripheral surface of the horizontal shaft portion 105b via a flat contact surface 118g so that the biasing force is directed to the long axis (center) of the horizontal shaft portion 105b. It is touched.

  In the cylindrical case 117, the case inner wall upper part 117b opposite to the spring member 118 is formed in a substantially semicircular arc shape, and includes two linear inclined surfaces set at a predetermined interval in the circumferential direction. A contact surface 117c is provided. The two contact surfaces 117c are formed at symmetrical positions with respect to the acting line F (see FIGS. 3 and 4) of the urging force of the spring member 118 acting on the horizontal shaft portion 105b. Abuts the outer surface. That is, the case inner wall upper portion 117b is configured to hold the circular outer surface portion of the horizontal shaft portion 105b urged by the spring member 118 toward the case inner wall upper portion 117b side at only two contact points, thereby forming a cylindrical shape. The case 117 and the horizontal shaft portion 105b are connected so as to be relatively rotatable. This contact corresponds to the “contact” in the present invention. By holding the horizontal shaft portion 105b in the above-described form, the horizontal shaft portion 105b has a straight line whose center is perpendicular to the line of action F of the urging force by the spring member 118 and the tangent line of each of the two contact points (method). It is held in a state where it coincides with the point (bearing center) where the line) intersects.

  The two contact surfaces 117c are formed over the entire long axis direction of the cylindrical case 117. For this reason, the contact between the contact surface 117 c and the horizontal shaft portion 105 b is substantially a line contact in the long axis direction of the cylindrical case 117. In the present embodiment, the line of action F of the urging force by the spring member 118 with respect to the horizontal shaft portion 105b and the two contact surfaces 117c in contact with the horizontal shaft portion 105b are equidistant in the circumferential direction, that is, 120 degrees apart. Is set in

  In addition, a cutout flat portion 105c is formed in a predetermined region in the circumferential direction at a portion of the outer peripheral surface of the large-diameter portion 105f of the horizontal shaft portion 105b that is in contact with the first and second elastic deflecting portions 118b. (See FIGS. 3, 8, and 9). The flat portion 105c corresponds to the “notch” in the present invention. The flat portion 105c is provided with first and second elastic deflecting portions 118b that act on the sun visor body 103 when the sun visor body 103 is rotated from the use position to the storage position and reaches a predetermined intermediate position. The force is set to be applied as a torque for forcibly rotating the sun visor body 103 toward the storage position. That is, when the sun visor body 103 is placed at a predetermined intermediate position, the contact surface 118g of the elastic deflecting portion 118b abuts with one end in the circumferential direction of the flat portion 105c of the horizontal shaft portion 105b. From this state, until the contact surface 118g is placed at the storage position where the flat portion 105c is brought into a flat contact state, the torque is continuously received in the direction toward the storage position.

  The fixing member 119 is assembled to the cylindrical case 117 by inserting a part of the fixing member 119 into the other opening of the cylindrical case 117. As shown in FIG. 8, the fixing member 119 has a penetrating shaft hole 119a. The small diameter portion 105g of the distal end of the horizontal shaft portion 105b inserted into the cylindrical case 117 is inserted into the shaft hole 119a in a penetrating manner and is prevented from coming off by appropriate means. As a result, the support shaft 105, the cylindrical case 117, and the spring member 118 are coupled to each other via the fixing member 119 to form a unit. The fixing member 119 may be assembled to the cylindrical case 117 after the support shaft 105 is attached to the cylindrical case 117. The fixing member 119 is smaller than the cylindrical case 117, that is, has a size that can be accommodated in the hollow portion of the sun visor body 103.

  FIG. 9 shows the support shaft 105, the cylindrical case 117, the spring member 118, and the fixing member 119 that are unitized as described above. Hereinafter, the unitized parts are referred to as unit parts 120. The unit component 120 is then assembled to the sun visor body 103. 10 to 13 show the step of attaching the unit component 120 to the sun visor main body 103 step by step. A concave notch 103a (see FIG. 10) for attaching the unit component 120 is formed at one corner of the upper edge of the two main body constituting members 103A and 103B constituting the sun visor main body 103.

  The unit component 120 is arranged so that the cylindrical case 117 is accommodated in the concave notch 103a of one main body constituting member 103A before the main body constituting members 103A and 103B are overlapped with each other. At this time, the fixing member 119 is placed inside the one main body constituting member 103A, and the support shaft 105 is placed so that the longitudinal axis portion 105a protrudes outward from the one main body constituting member 103A. This state is shown in FIG. Thereafter, the other main body constituting member 103B is superposed on one main body constituting member 103A. Thus, in the unit component 120, the cylindrical case 117 is disposed in the concave notch 103a of the main body constituting members 103A and 103B, and the fixing member 119 is accommodated in the hollow portion of the main body constituting members 103A and 103B. This state is shown in FIG.

  In a state where the main body constituting members 103A and 103B are overlapped with each other, a cylindrical mating portion 103b having an outer shape corresponding to the inner shape of the opening is formed at a portion facing one opening of the cylindrical case 117. Is done. The entire unit component 120 is linearly moved (slid) toward the cylindrical mating portion 103b and is fitted so that one opening of the cylindrical case 117 covers the cylindrical mating portion 103b from the outside. This state is shown in FIG. By the sliding movement of the unit component 120, the upper and lower recesses 119b formed in the fixing member 119 engage with the upper and lower protrusions 103c formed on the inner walls of the main body constituting members 103A and 103B (see FIG. 7). 120 movements in the sliding direction and the front-rear direction are restricted.

  Further, due to the above sliding operation, as shown in FIG. 13, a gap is generated between the other side end (left end) of the cylindrical case 117 and the end of the concave notch 103a of the main body constituting members 103A and 103B. A part of the fixing member 119 is exposed. In order to close (fill) the gap, an inverted U-shaped cap (cover) 121 is placed on the exposed portion of the fixing member 119 from above. The cap 121 has a locking projection 121a on the upper surface of the inner surface and a locking claw 121b on the lower surface of the inner surface. When the cap 121 is placed on the exposed portion of the fixing member 119, the locking projection 121a and the locking claw 121b are formed. The fixing member 119 is engaged with the upper concave portion 119b and the lower engaging step surface 119d. As a result, the cap 121 is fixed to the fixing member 119. Thus, the unit component 120 is attached to the sun visor body 103.

  In the mounted state of the unit component 120, the main body constituent members 103A and 103B are outside the mating surfaces by the cylindrical case 117 fitted so as to cover the cylindrical mating portions 103b of the two main body constituent members 103A and 103B from the outside. Opening (separating) can be restricted. Thereby, the proper joining state of the main body constituting members 103A and 103B is maintained. Further, the outer surface of the cap 121 that covers the exposed portion of the fixing member 119 is flush with the outer surface of the cylindrical case 117 and the outer surface of the sun visor main body 103, so that the outer surface without a step (unevenness) is formed. The vehicle sun visor 101 is configured.

  According to the present embodiment, two inclined contact surfaces 117c are set on the case inner wall upper portion 117b opposite to the spring member 118 of the cylindrical case 117 at a predetermined interval in the circumferential direction. Thus, the case inner wall upper portion 117b is held only at two contact points with the action line F of the urging force of the spring member 118 against the horizontal shaft portion 105b interposed therebetween. That is, the cylindrical case 117 intersects the center of the horizontal shaft portion 105b, the line of action F of the urging force by the spring member 118, and a straight line (normal line) perpendicular to the tangent line of the two contact points (that is, the bearing center). It is possible to hold the horizontal axis portion 105b in a state in which they match. For this reason, relative rotation between the horizontal shaft portion 105b and the cylindrical case 117 is performed in a state where there is no shaft shake (a phenomenon in which the rotation shaft is displaced in a direction intersecting the axis direction), and the sun visor body 103 is placed in the storage position. And the use position can be rotated stably and smoothly.

  Further, since the horizontal shaft portion 105b is configured to be held at two locations on the case inner wall upper portion 117b, the case inner wall upper portion of the cylindrical case 117 is formed in a highly accurate semicircular arc shape corresponding to the outer shape of the horizontal shaft portion 105b. There is no need. For this reason, the cylindrical case 117 is easy to make. The inclined contact surface 117c formed on the case inner wall upper portion 117b receives a circular cross section in the horizontal shaft portion 105b, that is, a region where the flat portion 105c for engaging with the spring member 118 is not formed. It is configured to receive. For this reason, a stable holding state is maintained even when the sun visor body 103 is placed in the storage position. The circular cross section corresponds to the “arc-shaped cross section” in the present invention.

  Further, according to the present embodiment, the holding region of the horizontal shaft portion 105b only by the two contact points of the case inner wall upper portion 117b sandwiches the action region of the urging force of the spring member 118 in the major axis direction of the horizontal shaft portion 105b. It is arranged on both sides. For this reason, it becomes effective in preventing the inclination of the axis line in the major axis direction of the horizontal shaft portion 105b and the cylindrical case 117.

  Further, in the present embodiment, the cylindrical case 117 for holding the support shaft 105 so as to be relatively rotatable is provided with an open concave notch 103a provided at one corner of the upper edge of the sun visor body 103. In addition to the arrangement, the outer shape of the sun visor main body 103 corresponds to the outer shape of the sun visor main body 103, that is, the outer surface of the cylindrical case 117 and the outer surface of the sun visor main body 103 are flush with each other. In other words, the cylindrical case 117 is exposed on the outer surface of the sun visor body 103. By adopting such a configuration, the cylindrical case 117 can be set larger than the conventional configuration in which the cylindrical case 117 is embedded in the sun visor main body 103, and as a result, the cylindrical case 117 is held by the cylindrical case 117. The diameter of the horizontal shaft portion 105b can be increased.

  The torque when the sun visor main body 103 is rotated between the storage position and the use position includes the biasing force of the spring member 118 and the sliding surface (between the horizontal shaft portion 105b, the spring member 118, and the cylindrical case 117). ) And the radius of the horizontal axis portion 105b. That is, the torque can be increased by increasing the diameter of the horizontal shaft portion 105b. According to the present embodiment, since the horizontal shaft portion 105b can be enlarged as described above, a high torque corresponding to an increase in the size (higher mass) of the sun visor body 103 is ensured and rotated to the use position. The moved sun visor main body 103 can be stably stopped at an arbitrary position, and the vehicle sun visor 101 with high usability is provided.

  Further, according to the present embodiment, the support shaft 105, the cylindrical case 117, the spring member 118, and the fixing member 119 are unitized, and the unitized unit component 120 is assembled to the sun visor body 103. By unitizing in this way, it can be handled as one component, and the assembling property with respect to the sun visor main body 103 can be improved. Further, when the unit part 120 is assembled to the sun visor main body 103, the opening of the cylindrical case 117 is fitted so as to cover the cylindrical mating portions 103b of the two main body constituting members 103A and 103B constituting the sun visor main body 103 from the outside. Therefore, the cylindrical case 117 functions as a regulating member that regulates the separation of the two main body constituting members 103A and 103B from the mating surfaces, and the state where the main body constituting members 103A and 103B are overlapped can be maintained.

  In the above-described embodiment, the sun visor for a vehicle is configured such that the sun visor main body 103 is formed into a hollow shell structure by joining the two half-divided main body constituting members 103A and 103B in the front-rear direction. However, the present invention can be applied to a vehicle sun visor in which the sun visor body 103 is formed of a resin foam molded body. This example is shown in FIGS. 14 to 16 as the second embodiment.

  14 shows the overall configuration of the vehicle sun visor according to the second embodiment, FIG. 15 is a cross-sectional view taken along the line GG in FIG. 14, and FIG. 16 is a cross-sectional view taken along the line H-H in FIG. The sun visor body 103 of the vehicle sun visor 101 according to the second embodiment is formed of a molded body of foam beads (polypropylene beads or polyethylene beads). The bearing structure of the support shaft 5 in the sun visor body 103 includes a cylindrical case 117 formed in a metal cylinder, a spring member 118 disposed in the internal space 117a of the cylindrical case 117, and the cylindrical case 117. Mainly composed of two fixing members 119A and 119B for fixing to the main body 103. The cylindrical case 117 corresponds to the “bearing portion” in the present invention, the internal space 117a corresponds to the “accommodating space” in the present invention, and the spring member 118 corresponds to the “elastic body” in the present invention. The spring member 118 is appropriately fixed to the lower part of the case inner wall of the cylindrical case 117 by fastening means.

One fixing member 119 </ b> A is fixed in a state where one end thereof is fitted into the internal space 117 a from one opening of the cylindrical case 117, and is joined to one end of the reinforcing wire 123 disposed in the sun visor body 103. Is done. The other fixing member 119 </ b> B is fixed in a state where one end thereof is fitted into the internal space 117 a from the other opening of the cylindrical case 117 and is joined to the other end of the reinforcing wire 123. The two fixing members 119A and 119B are embedded in the sun visor main body 103 together with the reinforcing wire 123 when the sun visor main body 103 is formed by foaming beads. Thus, the cylindrical case 117 is fixed to the sun visor body 103 by the two fixing members 119A and 119B. The cylindrical case 117 is exposed on the surface of the sun visor main body 103, and the exposed outer surface is flush with the outer surface of the sun visor main body 103. As a result, the vehicle sun visor 101 having an outer surface without a step (unevenness) is formed.
Except for the structure for fixing the cylindrical case 117 to the sun visor body 103 described above, the other points are substantially the same as those of the first embodiment described above.
