Description

  The present invention relates to an auxiliary mirror for a vehicle that is used in the vicinity of a side mirror.

  For example, a vehicle auxiliary mirror (hereinafter simply referred to as “auxiliary mirror”) as shown in Non-Patent Document 1 for the purpose of confirming obstacles and people hidden behind the vehicle body when driving a truck. It is common practice to attach a small mirror called near the side mirror.

  As shown in FIG. 7, the conventional auxiliary mirror 1 includes a mirror main body 2, an arm 3 protruding from the side edge of the mirror main body 2 toward the side, and an attachment portion 4 attached to the tip of the arm 3. And is roughly composed.

  The attachment part 4 is configured as a clip-like thing divided into two parts, and a stick-like attachment stay S extending vertically is attached between the clip-like attachment part 4 and attached to the base part. The auxiliary mirror 1 can be clamped and fixed to the mounting stay S by tightening the bolts and nuts 5. If the bolts and nuts 5 are loosened, the height can be adjusted by moving the bolts and nuts up and down, and the angle can be adjusted by swinging the neck around the mounting stay S. When the bolts and nuts 5 are tightened at the stage where the adjustment is completed, they can be fixed at the adjustment position.

  However, the mounting stay S is not only a rod-like one extending in the vertical direction as described above, and this is often seen in 2t tracks. However, as shown in FIG. Some of them extend downward from the lower side, bend in the middle, and further extend toward the vehicle body. Hereinafter, this is referred to as “curved attachment stay S”.

  When the auxiliary mirror 1 shown in FIG. 7 is attached to such a curved attachment stay S, the attachment portion 4 is fixed to the vertical portion Y extending downward from the lower side of the side mirror M. . As a result, the mirror body 2 is positioned at a position away from the mounting stay S by the amount of the arm 3 (an obliquely lower position that is largely out of the side mirror M).

  In this case, when the side mirror M and the auxiliary mirror 1 at a diagonally lower position greatly deviated from the side mirror M are viewed alternately, the eyes are not simply moved in the vertical direction, but also in the diagonally outward direction. There is a problem that the movement of such a large line of sight has a very high degree of fatigue, and the forward attention is distracted and there is a high risk because it is an operation during driving.

  In addition, the auxiliary mirror 1 greatly disengaged from the side mirror M may possibly come into contact with an oncoming vehicle or a pedestrian, which is not preferable from the viewpoint of traffic safety.

  Further, since the auxiliary mirror 1 is for viewing a blind spot that does not enter the side mirror M, its movable range must be large. However, as described above, the attachment range of the auxiliary mirror 1 is limited to the vertical portion Y and cannot be attached to the curved portion X. The range in which the auxiliary mirror 1 can be attached to the curved attachment stay S is as follows. Very narrow and limited range of motion.

  The present invention can be mounted not only on the vertical part of the curved mounting stay, but also on the curved part provided in the middle, so that the movable range is very large, and it can be installed directly under the side mirror and viewed alternately with the side mirror. It is to provide an auxiliary mirror in which the line of sight only needs to be moved in the vertical direction.

The invention described in claim 1 includes: “the housing 12 having the mirror 40 attached to the front surface thereof, and the attachment member 18 attached to the back surface of the housing 12, In the attachment, the side mirror M is provided at the upper end of the vertical portion Y that extends horizontally from the vehicle body, curves downward in a U-shape from the tip of the horizontal portion Z, and extends upward from the tip of the curved portion X. A vehicle auxiliary mirror 10 that is clamped and fixed to a stay S,
A concave groove 28 is provided at the center of the back surface of the housing 12 so as to extend in the vertical direction and to follow the vertical portion Y of the mounting stay S.
The lower part of the rear surface of the housing 12 on the side close to the vehicle body with the concave groove 28 as a boundary is cut off so as to be substantially continuous with the groove bottom of the concave groove 28, and is arranged so that the curved portion X of the mounting stay S is along. A plane portion 32 is provided,
A center fixing hole 30a for fixing one end portion of the mounting member 18 is formed in the vehicle body side raised portion 33a that bulges in the back at the upper back of the housing 12 on the side close to the vehicle body with the concave groove 28 as a boundary. Established,
A plurality of adjustment fixing holes 30b and 30c for fixing the other end of the mounting member 18 are formed on the outer bulge portion 33b that bulges backward on the opposite side of the vehicle body bulge portion 33a with the concave groove 28 as a boundary. Is drilled,
The adjustment fixing holes 30b and 30c are provided on the same arc centered on the center fixing hole 30a. "

  According to the auxiliary mirror 10 for a vehicle according to claim 1, the vertical portion Y of the mounting stay S is placed in the concave groove 28 provided in the center of the back surface of the housing 12, and the mounting member 18 and the back surface of the housing 12 are arranged. Since the mounting stay S can be clamped and fixed, the auxiliary mirror 10 can be installed directly under the side mirror M, and the movement of the eyes when looking at the side mirror M and the auxiliary mirror 10 can be limited up and down. Can be kept. In other words, when the side mirror M and the auxiliary mirror 10 are viewed alternately, the movement of the line of sight is small, and fatigue during driving can be reduced. Further, the protrusion of the auxiliary mirror 10 to the outside of the side mirror M can be avoided, which can contribute to traffic safety.

  In addition, since the flat portion 32 is provided on the side near the vehicle body at the lower part of the back surface of the housing 12, the mounting stay S extends downward from the lower side of the side mirror M and curves in the middle thereof. The curved portion X of the mounting stay S can be arranged on the plane portion 32, and the mounting stay S does not buffer the housing 12 when the housing 12 is attached.

  Furthermore, since the relationship between the center fixing hole 30a and the plurality of adjustment fixing holes 30b, 30c maintains the above positional relationship, the mounting position of the auxiliary mirror 10 can be lowered to the curved portion X of the mounting stay S, and the auxiliary The movable range of the mirror 10 can be taken up to the curved portion X, and the adjustment range can be greatly expanded (see FIGS. 4 to 5).

It is a figure which shows the use condition of the auxiliary | assistant mirror for vehicles of this invention. It is a disassembled perspective view of the auxiliary mirror for vehicles of the present invention. It is a rear view of the housing | casing of this invention. It is a rear view at the time of attaching the auxiliary mirror for vehicles of the present invention to the vertical portion of the attachment stay.

FIG. 4 is a cross-sectional view taken along line A-A ′ in FIG. 3. It is a figure which shows a prior art example. It is a figure which shows the other example of attachment of a prior art example.

  The present invention will be described below with reference to the drawings. FIG. 1 is a view showing a use state of a vehicle auxiliary mirror 10 (hereinafter simply referred to as “auxiliary mirror 10”) according to the present invention, and FIG. 2 is an exploded perspective view of the auxiliary mirror 10 according to the present invention. is there. As shown in these drawings, the auxiliary mirror 10 of the present invention is roughly constituted by a housing 12, a mirror member 14, a mirror fixing member 16, an attachment member 18, and a cover member 20.

  The housing 12 is a shallow box-shaped member whose front side is open, and 12a is the back plate. A mirror member 14 to be described later is accommodated in the mirror accommodating portion 22 which is the opening space. The outer shape of the housing 12 can adopt an arbitrary shape. In this embodiment, the lower side is shorter than the upper side, and the surface closer to the vehicle body (the left side in FIG. 1) has a gentle convex shape. It is formed to be a curved surface.

  As shown in FIG. 3, a concave groove 28 extending from the upper side to the lower side is formed in the center of the back surface of the back plate 12 a of the housing 12. In other words, the shape of the front side of the groove 28 protrudes forward in a vertical hook shape. The cross-sectional shape of the concave groove 28 is formed in a semicircular shape in accordance with the vertical portion Y of the mounting stay S to which the auxiliary mirror 10 is to be mounted.

  The lower part of the back surface of the back plate 12a of the housing 12 and the side close to the vehicle body with the groove 28 as a boundary (the right lower part in FIG. 3) substantially coincides with the groove bottom of the groove 28 and is flush with the plane. The flat portion 32 for receiving the curved portion X of the mounting stay S is provided.

  The flat portion 32 is cut to substantially the same depth (or slightly higher position) as the bottom of the concave groove 28, and the back plate 12a on the opposite side beyond the upper portion of the flat portion 32 and the concave groove 28 is The back is raised in a step shape. This portion is a vehicle body side bulge portion 33a, and the opposite side is an outer bulge portion 33b.

  A center fixing hole 30a for fixing a mounting member 18 to be described later is formed in the rear upper end portion of the housing 12 and in the vehicle body side raised portion 33a. A plurality of (in this case, two) adjustment fixing holes 30b and 30c are formed in the outer bulge portion 33b. The adjustment fixing holes 30b and 30c are provided on the same arc centered on the center fixing hole 30a. When one of the adjustment fixing holes 30b is drawn toward the center fixing hole 30a, a straight line L1 is drawn. L1 is provided at a position orthogonal to the concave groove 28 (see FIG. 4). When the other adjustment fixing hole 30c is drawn with a straight line L2 toward the center fixing hole 30a, the straight line L2 is attached to the mounting stay S. A center line parallel to the tangent line of the curved portion X is provided at an angle substantially orthogonal to the intersecting portion with the curved portion X (see FIG. 5).

  The above “on the same circular arc” does not mean a strict geometrical thing. As described later, when the mounting hole 19 provided in the mounting member 18 is a long hole, this is used. The attachment member 18 includes a range in which the fixing member 18 can be screwed to any of the adjustment fixing holes 30b and 30c around the center fixing hole 30a. Further, “orthogonal” does not necessarily mean an exact mathematical thing, and it is sufficient that the mounting stay S is fixed at an angle close to 90 ° with respect to the vertical portion Y of the mounting stay S. Is in the range of approximately 90 ° ± 10 °.

  In addition, a rectangular recess 33c (as viewed from the back) is formed at the center of the outer rising portion 33b on the side farther from the vehicle body (the left side in FIG. 3) of the back plate 12a of the mirror housing portion 22 beyond the concave groove 28. The hemispherical mirror mounting portions 24 and 34 protrude from the front and back surfaces of the rectangular recess 33c corresponding to the same position. Is provided. Further, insertion holes 26 for inserting support members 48 projecting from both ends of a main body plate 16a of the mirror fixing member 16 described later are formed on the left and right sides of the mirror mounting portion 24, respectively.

  Further, a locking hole 36 for attaching a cover member 20 to be described later is formed along the outer edge of the outer raised portion 33b at the upper end portion and the lower end portion of the outer raised portion 33b.

  The mirror member 14 is roughly composed of a base 38 and a mirror 40. The base 38 is a plate-like member, and its outer shape is set slightly smaller than the inner peripheral shape of the mirror housing part 22 so that it can be housed in the mirror housing part 22 of the housing 12.

  A hemispherical base-side recess 42 into which the front-side mirror mounting portion 24 is fitted is recessed at the back side of the base 38 and corresponding to the front-side mirror mounting portion 24 of the housing 12. A pair of left and right nut housing recesses 44 are provided on the front side of the base 38 and on both sides of the base side recess 42, and a round hole 44a is formed at the bottom of the nut housing recess 44. Is formed.

  A mirror 40 is attached to the front side of the base 38. In this embodiment, the mirror 40 employs a “planar mirror” that can easily grasp the shape and sense of distance of an object. However, a “convex mirror” that facilitates visual recognition of a wider range may be employed.

  The mirror fixing member 16 has a main plate 16a which is a horizontally long flat plate member. A hemispherical fixing member side recess 46 is formed at the center of the front surface of the main body plate 16a. Cylindrical support members 48 sandwich the fixing member side recess 46 between the left and right sides of the front surface of the main body plate 16a. It is projected in a way.

  The pair of left and right support members 48 are respectively inserted into the insertion holes 26 of the housing 12, and their tips are in contact with the back surface of the base 38. A separately prepared bolt 50 is inserted into a hole 48a provided at the center of the support member 48, and a nut 52 is screwed to the insertion end of the bolt 50 that has passed through the support member 48 and the round hole 44a of the base 38. The Thereby, the mirror member 14 is fixed to the housing | casing 12 (refer FIG. 6).

  Here, under tightening by the bolt 50 and the nut 52, the hemispherical front side mirror mounting portion 24 can slide in the hemispherical base side recess 42 of the base 38 with appropriate contact resistance. Spherical contact is made and the hemispherical rear surface side mirror mounting portion 34 is slidably spherically contacted with the hemispherical fixing member side recess 46 of the mirror fixing member 16 with appropriate contact resistance (see FIG. 6). . As a result, when the end of the mirror member 14 is pushed with a finger, the mirror member 14 moves up and down around the front-side mirror mounting portion 24 and the rear-side mirror mounting portion 34 that are the contact portions with the mirror mounting portion 24 of the housing 12. The head can be swung left and right, and the angle of the mirror 40 can be adjusted freely.

  The mounting member 18 is a plate-like member whose central portion is curved in a substantially U shape, and mounting holes 19 for inserting bolts are provided on both sides of the mounting member 18 in the center fixing hole 30a and the adjusting fixing hole 30b. It is formed according to the position.

  The mounting hole 19 is a long hole formed along the longitudinal direction of the mounting member 18, and the position of the adjustment fixing holes 30b and 30c with respect to the center fixing hole 30a is such that one of the mounting holes 19 is the center fixing hole 30a. It is only necessary to be within an adjustment range in which the other mounting hole 19 can be fixed to the adjustment fixing holes 30b and 30c. Therefore, the meaning of “on the same arc” of the adjustment fixing holes 30b and 30c with respect to the center fixing hole 30a is sufficient as long as it is within the range provided in the adjustment range on the outer rising portion 33b.

  One adjustment fixing hole 30b is provided at a position where the straight line L1 is orthogonal to the groove 28 when the straight line L1 is drawn toward the center fixing hole 30a, and the other adjustment fixing hole 30c is When the straight line L2 is drawn toward the center fixing hole 30a, the straight line L2 is perpendicular to the center line of the curved portion X parallel to the tangent to the curved portion X at the intersection of the mounting stay S with the curved portion X. It is provided at an angle. The meaning of “orthogonal” is not used in the strict sense as described above, and an angle substantially close to 90 ° is sufficient.

  The cover member 20 serves as a member (blindfold member) that hides the back surface portion of the housing 12 when the housing 12 is attached to the attachment stay S, and a portion corresponding to the locking hole 36 of the housing 12 includes: A locking claw 56 is formed. In addition, on the inner surface portion of the cover member 20 that coincides with the concave groove 28 of the housing 12, two stay pressing convex ridges 55 project in parallel to the concave groove 28.

  When the auxiliary mirror 10 of this embodiment is attached to the track mounting stay S, the concave groove 28 of the housing 12 is placed along the vertical portion Y of the mounting stay S suspended from the side mirror M, and the mounting member 18 is attached. The mounting member 18 is mounted from the back side of the housing 12 so that the mounting hole 19, the center fixing hole 30 a of the housing 12, and the adjustment fixing holes 30 b arranged side by side coincide with each other.

  Then, the tip of a screw 58 (see FIG. 4) prepared separately is inserted into the attachment hole 19 of the attachment member 18 and the fixing holes 30a and 30b of the housing 12, respectively, and the tip is aligned with the fixing holes 30a and 30b. Screw into the arranged nut (not shown). Instead of the nut, screw holes may be formed in the fixing holes 30a and 30b and screwed into the screw holes. As a result, the auxiliary mirror 10 is attached to the attachment stay S (see FIG. 4).

  Then, the cover member 20 as a blindfold member is applied from the back side of the housing 12, and the cover member 20 is attached to the housing 12 by locking the locking claws 56 in the locking holes 36 of the housing 12.

  In the above-described example, the attachment member 18 is attached from the rear side of the housing 12 by using the center fixing hole 30a of the housing 12 and one adjustment fixing hole 30b located side by side with the center fixing hole 30a. Although the housing 12 is fixed to the stay S, for example, as shown in FIG. 5, the center fixing hole 30a and the other adjustment fixing hole 30c located below the one adjustment fixing hole 30b. And may be used. In this case, since the attachment position of the auxiliary mirror 10 can be lowered to the curved portion X of the attachment stay S, the movable range of the auxiliary mirror 10 can be taken to the curved portion X.

  In any case, the mounting member 18 is fixed so as to be perpendicular to the center line of the vertical portion Y and the curved portion X of the mounting stay S. Thus, the auxiliary mirror 10 is firmly fixed to the mounting stay S.

  According to the auxiliary mirror 10 of the present embodiment, the vertical portion Y of the mounting stay S is placed along the concave groove 28 provided in the center of the back surface of the housing 12, and the mounting stay S is formed by the mounting member 18 and the back surface of the housing 12. Since the auxiliary mirror 10 can be installed directly below the side mirror M, the movement of the eyes when looking at the side mirror M and the auxiliary mirror 10 can be limited up and down, and safety during driving can be maintained. I can do it. In other words, when the side mirror M and the auxiliary mirror 10 are viewed alternately, the movement of the line of sight is small, and fatigue during driving can be reduced. Further, the protrusion of the auxiliary mirror 10 to the outside of the side mirror M can be avoided, which can contribute to traffic safety.

  Since the flat surface portion 32 is provided on the lower back side of the housing 12 and closer to the vehicle body, the mounting stay S extends downward from the lower side of the side mirror M, and is curved in the middle. The curved portion X of the mounting stay S can be arranged on the plane portion 32, and the mounting stay S does not buffer the housing 12 when the housing 12 is attached.

  Furthermore, since the relationship between the center fixing hole 30a and the plurality of adjustment fixing holes 30b, 30c maintains the above positional relationship, the mounting position of the auxiliary mirror 10 can be lowered to the curved portion X of the mounting stay S, and the auxiliary The movable range of the mirror 10 can be taken up to the curved portion X, and the adjustment range can be greatly expanded.
