[Industrial applications]

 The present invention relates to a mirror angle adjusting mechanism for a vehicle mirror.

[0002]

[Prior art]

 In automobiles such as trucks, outside mirrors are attached to the front left and right sides of the vehicle body. Usually, the outside mirrors are attached to the vehicle body through an angle adjusting mechanism so that the angle can be adjusted. FIG. 14 is a front view of the outside mirror described above, and FIG. 15 is an exploded perspective view of the angle adjusting mechanism. In these drawings, 100 is a vehicle body, 101 is a columnar column fixed to the vehicle body, and 102 is an outside mirror. , H is a mirror housing of the outside mirror 102, 103 is a bracket provided on the mirror housing H, 104 is a holding portion attached to the bracket 103 via a screw, and the outside mirror 102 is provided with an angle adjusting mechanism 105. Is attached to the column 101 so that the angle can be adjusted. The angle adjusting mechanism 105 includes a holding portion 106 fixed to the support column 101 and an engaging portion 107 formed on the bracket 103 and the pressing portion 104. The holding portion 106 has a spherical outer periphery 108. None, and it is composed of a pair of halves whose top and bottom are cut flat to form a ring. On the other hand, the engaging portion 107 is formed in a shape matching the outer circumference 108 of the holding portion 106, that is, a spherical concave portion. The holding portion 106 is located between the bracket 103 and the holding portion 104, and the holding portion 105 is held between the bracket 103 and the holding portion 104 by tightening the bracket 103 and the holding portion 104 with screws 109. It Since the outer circumference 106 of the holding portion 105 is spherical and the engaging portion 107 is a spherical concave portion, the mirror housing H is rotatable in all directions with respect to the holding portion 105 via the engaging portion 107. The angle of the outside mirror 102 can be adjusted.

[0003]

However, in such a conventional outside mirror mounting structure, the outer periphery 108 of the holding portion 106 and the engaging portion 107 must be formed in a spherical shape. Since it is necessary to accurately measure the sphericity of the part, it is not easy to manufacture. Further, since the outer circumference 108 of the holding portion 106 and the engaging portion 107 are spherical, the outside mirror 102 can be tilted in any direction, so that the mirror housing H is inclined with respect to the column 101 (A in FIG. 14). There was a problem that the appearance deteriorated if it was tilted in the direction). Further, since the upper and lower parts of the holding part 106 are cut, the contact area between the holding part 106 and the engaging part 107 may change depending on the tilting direction of the mirror housing H. Since the required torque changes, it is difficult to adjust the angle of the outside mirror 102.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a vehicle in which a mirror housing of an outside door mirror is attached to a columnar pillar provided on the vehicle body side through an angle adjusting mechanism, and the angle adjusting mechanism is attached to the pillar. The holding part to be attached and the engaging part provided on the mirror housing side and engaged with the outer periphery of the holding part are formed with a cylindrical hole having a circular cross section, and the cylindrical hole is formed into the pillar. The outer periphery of the holding member is rotatably engaged, and a circular outer peripheral portion is formed on the outer peripheral surface of the holding member in a direction orthogonal to the axial direction of the support post. The portion is rotatably engaged with the outer peripheral portion of the holding member.

[0005]

[Action]

 The tilting angle of the mirror housing in the left-right direction can be adjusted by rotatably attaching the holding part to the column, and also with respect to the outer peripheral part of the holding member formed in a tubular shape in the direction orthogonal to the axial direction of the column. The vertically tilting angle of the mirror housing can be adjusted by rotatably engaging the engaging portion. Since the support pillar and the holding member are engaged with each other through the cylindrical hole, and the outer periphery of the holding member and the engaging portion are also engaged with each other through the cylindrical hole, it is possible to eliminate the previously required spherical engaging portion. Since the tubular shape is easier to form than the spherical shape, the manufacturing of the angle adjusting mechanism can be facilitated, and the appearance can be improved because the mirror housing does not tilt in an oblique direction. Further, since the contact area between the support and the holding member and the engagement between the holding member outer periphery and the engaging portion is always constant, the torque required for the angle adjustment of the mirror housing becomes constant, which facilitates the angle adjustment of the mirror housing. It can be carried out.

【Example】

 A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a front view of the outside mirror, FIG. 2 is a sectional view taken along line 2-2 of FIG. 1, and FIG. 3 is an exploded perspective view of the outside mirror. In the figure, reference numeral 1 denotes a vehicle body, and a columnar support 2 is attached to a side portion of the vehicle body 1. The support pillar 2 has a U-shape in a front view in which the upper and lower sides are bent. It's fixed. A holding member 3 is attached to the column 2 so as to be rotatable about an axis, and the holding member 3 is composed of a pair of holding pieces 3a and 3b. The holding pieces 3a and 3b are provided with a convex portion 4 and a hole portion 5, respectively. The holding pieces 3a and 3b are integrated by forming them and engaging the convex portions 4 and the hole portions 5 with each other. In this embodiment, the holding portion 3 is composed of a pair of holding pieces 3a and 3b. However, this may not be a pair but one member or two or more members. . The holding portion 3 has a cylindrical hole 6 having a circular cross section, and when the cylindrical hole 6 is engaged with the supporting column 2, it becomes rotatable about the axial direction of the supporting column 2 as described above. Further, the holding portion 3 has a cylindrical outer peripheral portion 7 in a side view (viewed in the direction B in FIGS. 1 and 3), and as shown in FIG. 1, the axial center direction line L1 of the outer peripheral portion 7 is the strut. It is a direction orthogonal to the axial center direction L2 of 2.

Reference numeral 8 denotes a mirror housing. The mirror housing 8 holds a mirror 9 on its rear surface side, and a bracket 10 is integrally formed on the vehicle body side of the mirror housing 8. The bracket 10 is a mirror housing. 8 and a block portion 11 formed integrally with the block portion 8 and a pressing portion 13 attached to the block portion 11 via screws 12. The bracket 10 is formed with a cylindrical hole-shaped engaging portion 14 corresponding to the outer peripheral portion 7 of the holding member 3 and a hole portion 16 having a shape corresponding to the support column 2, and the engaging portion 14 includes the block. It is formed over both the portion 11 and the pressing portion 13. The engaging portion 14 is rotatably engaged with the outer peripheral portion 7, so that the bracket 10, that is, the mirror housing 8 can be tilted up and down about an axis L1 orthogonal to the column 2. Reference symbol S denotes an escape portion formed on the bracket 10 for ensuring the rotation of the mirror housing 8 about the axis L1. (Note that the mirror housing 8 is rotatable only around the axis L1 with respect to the holding member 3 and is not rotatable in other directions.) Assembling of the block portion 11 and the holding member 3 is performed by the holding member. After fitting 3 to the support 2, the holding member 3 is sandwiched between the block portion 11 and the pressing portion 13, and in this state, the block portion 11 and the pressing portion 13 are fastened with a constant force via the screws 12 ... Done in. The column 2, the holding member 3, the engaging portion 14 and the like constitute an angle adjusting mechanism 15.

In the above, if a horizontal force is applied to the mirror housing 8 toward the front or rear of the vehicle body, the bracket 10 cannot rotate relative to the holding member 3 in this direction. It is transmitted to the holding member 3 via the mirror housing 8 and rotates together with the support member 3 about the axial direction L2 of the column 2. By the rotation of the mirror housing 8, the mirror housing 8 tilts forward or backward around the support column 2, and the horizontal field of view of the mirror 9 is adjusted. On the other hand, if a force is applied to the mirror housing 8 in the vertical direction, that is, the direction C in FIG. 2, the bracket 10 can rotate relative to the holding member 3 in this direction. It rotates around the axis L1 of axis 3. By this rotation of the mirror housing 8, the mirror housing 8 is tilted up and down about the axis L1, and the vertical field of view of the mirror 9 is adjusted.

By the way, in this embodiment, the holding member 3 is rotatably engaged with the support column 2 through the circular cylindrical hole 6, and the bracket 10 is also attached to the outer peripheral portion 7 through the cylindrical engaging portion 14. It is rotatably engaged. Therefore, all of these engagements that contribute to the angle adjustment in the front-rear direction and the up-down direction of the mirror housing 8 need only be formed in a cylindrical shape with an outer circumference, and the engaging portion is made spherical as in the conventional case. The manufacturing is simpler than that requiring sphericity, and the angle adjusting mechanism can be manufactured easily. Further, in this embodiment, since the contact area of the engagement between the holding member 3 and the support column 2 and the engagement between the outer peripheral portion 7 of the holding member 3 and the engagement portion 14 is always constant, the angle adjustment of the mirror housing 8 is performed. The force required for this is always constant, which facilitates the angle adjustment of the mirror housing 8. Further, since the holding member 3 and the support column 2 are engaged with each other, and the outer peripheral portion 7 of the holding member 3 and the engaging portion 14 are engaged with each other, both are in surface contact with the cylinder, and the tightening force acts on the outer circumference of the cylinder. The holding force of the mirror housing 8 does not change much due to the variation of the above, and a stable holding force can be secured. Further, according to the structure of this embodiment, the mirror housing 8 is inclined only around the axial line L 1 of the holding member 3 and around the axial line L 2 of the support column 2, and in other directions, for example, the D direction in FIG. Since the mirror housing 8 does not tilt, the mirror housing 8 does not tilt obliquely when viewed from the front, and it is possible to prevent the appearance from deteriorating.

FIG. 4 is a front view of an outside mirror according to another embodiment, and FIG. 5 is a sectional view taken along line 5-5 of FIG. In this embodiment, the column 2 extends horizontally from the vehicle body, and the bracket 10 is formed in the upper front portion of the mirror housing 8 in the horizontal direction. The angle adjusting mechanism 15 has the same structure as that of the previous embodiment, but the support column 2 penetrates the bracket 10 so that the support column 2 can be attached from either the left side or the right side. The other structures and effects are the same as in the previous embodiment. 6 is a front view of an outside mirror according to still another embodiment, and FIG. 7 is a sectional view taken along line 7-7 of FIG. In this embodiment, the support column 2 extends laterally from the vehicle body and its tip extends further downward (only the portion extending downward is shown in the figure), and the block portion 11 of the mirror housing 8 is shown. It is formed on the inner surface. The other structure is similar to that of the first embodiment. 8 is a front view of an outside mirror according to another embodiment, FIG. 9 is a sectional view taken along line 9-9 of FIG. 8, and FIG. 10 is an exploded perspective view. In this embodiment, the pillar 2 extends laterally from the vehicle body, and the block portion 11 is formed on the inner surface of the mirror housing 8. The other structure is similar to that of the first embodiment. 11 is a front view of an outside mirror according to still another embodiment, FIG. 12 is a sectional view taken along line 12-12 of FIG. 11, and FIG. 13 is an exploded perspective view thereof. In this embodiment, the holding member 3 is formed of a pair of holding pieces 3a and 3b as in the first embodiment, but the structure is different. That is, conical portions 3a2 and 3b2 are formed outside the holding pieces 3a and 3b, and flat surface portions 3a1 and 3b1 are formed at the ends of the conical shape. The flat surface portion 3a1 abuts on the flat surface portion 19 formed on the block portion 11, the flat surface portion 3b1 abuts on the flat surface portion 20 formed on the pressing portion 13, and the conical portion 3a2 forms the inner conical surface formed on the block portion 11. The conical portion 3b2 comes into contact with the inner conical receiving portion (not shown, which has the same shape as the receiving portion 21) formed in the pressing portion 13. The structure in which the cylindrical hole 6 is rotatably engaged with the support column 2, the structure in which the outer peripheral portion 7 is rotatably engaged with the engaging portion 14, and the like are the same as in the previous embodiment. According to the structure of this embodiment, the conical portion 3a2 abuts on the inner conical receiving portion 21 and the conical portion 3b2 abuts on the inner conical receiving portion, that is, the abutting portion has a conical shape. When the screws 12 are tightened, this force is directed to the center line L1 via the conical shape, so that the tightening force can be concentrated in the direction of the center L1 without dispersing the tightening force to obtain a large tightening force.

[Effect of device]

 As described above, according to the present invention, the tilting angle in the left-right direction of the mirror housing can be adjusted by rotatably attaching the holding portion to the support, and the cylinder can be moved in the direction orthogonal to the axial direction of the support. The vertically tilting angle of the mirror housing can be adjusted by rotatably engaging the engaging portion with the outer peripheral portion of the holding member formed in a shape. Since the pillar and the holding member are engaged with each other through the cylindrical hole, and the outer periphery of the holding member and the engaging portion are also engaged with each other through the cylindrical hole, it is possible to eliminate the previously required spherical engaging portion. However, since it is easier to form a tubular shape than a spherical shape, the angle adjusting mechanism can be easily manufactured, and the appearance is improved because the mirror housing does not tilt in an oblique direction. Furthermore, since the contact area between the support and the holding member and the engagement between the holding member outer periphery and the engaging portion is always constant, the torque required to adjust the angle of the mirror housing is constant, and the angle of the mirror housing can be adjusted easily. be able to.
