Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting device for a removable mirror for a vehicle that is mounted diagonally above the driver's seat.

(Prior Art) This type of removable mirror is designed to fall off if the head or face of the driver or passenger hits it in the event of a sudden stop or collision, thereby preventing injury. However, due to normal vibrations and external forces when adjusting the mirror, the structure of the mounting part needs to be firmly attached to a certain extent to prevent it from falling off or changing the mounting angle to the vehicle body, making the structure of the mounting part complicated. It is easy to become. For example, in 1987-
The device disclosed in Publication No. 96402 requires parts such as a base and a bracket in addition to two leaf springs, and also requires fixing the leaf spring to the base, fixing the base to the vehicle body, and fixing the bracket and mirror stay. The number of parts that require fixing work, such as fixing to a vehicle, is increasing, and the structure is complex and has a large number of parts, making assembly work time-consuming.

(Problem to be solved by the invention) The present invention has focused on this point and has been devised for the purpose of providing a mounting device for a removable vehicle mirror that has a simple structure, a small number of parts, and is easy to assemble. It is.

(Means for Solving the Problems) That is, in the present invention, a rectangular leaf spring having a square bracket insertion hole in the center is provided with a rectangular plate spring having a square bracket insertion hole formed inwardly in a V-shape on a pair of opposing side edges of the bracket insertion hole. A pair of engagement spring pieces are provided protrudingly provided, and a pair of first screw holes are provided on both sides thereof, and a short prismatic bracket corresponds to the engagement spring pieces at the end on the vehicle body plate side. It has a pair of protruding engaging shoulders and a female threaded hole in the center, and the mounting part integrated with the mirror stay has a recessed leaf spring hole large enough to accommodate a leaf spring, bracket, etc. with a second center in the center.
A screw hole is provided, and a positioning protrusion is formed on the surface that contacts the vehicle body plate, and a positioning hole into which the positioning protrusion is inserted is provided in the vehicle body plate.
A third screw hole corresponding to the first screw hole is provided, and the bracket is inserted into the bracket insertion hole of the leaf spring, and while temporarily holding the bracket, insert the first screw into the first screw hole and the third screw hole. Attach the leaf spring to the vehicle body plate by inserting the second screw into the screw hole No. 3, then cover the mounting part of the mirror stay over the leaf spring and the bracket, insert the positioning protrusion into the positioning hole, and insert the second screw into the second screw. By inserting the bracket into the hole and screwing it into the female threaded hole, the bracket is pulled toward the mounting part, the engaging shoulder part is pressed against the engaging spring piece, and the mounting part is pressed against the vehicle body plate, and the mirror stay is attached to the vehicle body. This invention provides a mounting device for a removable mirror for a vehicle, which is characterized in that it is mounted on an internal body plate.

(Function) Therefore, according to the present invention, the assembly is completed by inserting the bracket into the bracket insertion hole, attaching the temporarily held plate spring to the vehicle body, and attaching the mirror stay to the bracket. If the mirror can be held, and a force exceeding a certain limit is applied, the engagement spring piece of the leaf spring will deform and disengage from the engagement shoulder of the bracket, causing the bracket to come out from the leaf spring and release the mirror. Since the stay falls off, the structure is extremely simplified compared to the conventional example described above, and the assembly work can be easily performed.

(Example) Hereinafter, the present invention will be specifically explained with reference to an example shown in the drawings.

In the figure, 1 is a mirror stay that supports a room mirror (not shown) at its tip, 2 is a car body plate, 3 is an attachment part of the mirror stay 1 to the car body, 4 is a leaf spring,
5 is a bracket. The leaf spring 4 is rectangular with a square bracket insertion hole 6 in the center.
A pair of engagement spring pieces 7 are protruded inward from a pair of opposing side edges of the bracket insertion hole 6 in a V-shape, and are opposed to the leaf spring 4 provided with the engagement spring pieces 7. A pair of first screw holes 8 are drilled on both sides of the vehicle body plate 2 with the first screws 9 and nuts 10.
It is designed to be screwed into place.
This leaf spring 4 is constructed by processing a metal plate made of spring material or by molding a highly elastic synthetic resin. The bracket 5 has a short prismatic shape, and has a pair of engagement shoulders 11 protruding from the end on the vehicle body plate 2 side in correspondence with the engagement spring pieces 7, and a female threaded hole 12 in the center. The mirror stay 1 is screwed to the mounting portion 3 of the mirror stay 1 by a second screw 13. The mounting portion 3 is provided with a leaf spring hole 14 large enough to accommodate the leaf spring 4, bracket 5, etc. A second screw hole 15 is provided at the center of the bottom of the recessed leaf spring 14, and positioning protrusions 16 are formed on the surfaces in contact with the vehicle body plate 2 on the tip sides of both sides.

Furthermore, the positioning protrusion 16 is provided on the vehicle body plate 2.
A positioning hole 2a is provided at a position corresponding to the screw hole 8, and a third screw hole 2b is provided at a position corresponding to the screw hole 8.

Assembly is performed as follows. That is, the bracket 5 is inserted into the bracket insertion hole 6 of the leaf spring 4, the engagement spring piece 7 of the leaf spring 4 is engaged with the engagement shoulder 11 of the bracket 5, and the bracket 5 is temporarily held. The leaf spring 4 is attached to the vehicle body plate 2 by inserting the screw 9 of No. 1 into the first screw hole 8 and the third screw hole 2b and screwing it into the nut 10.
Cover the mounting part 3 of the mirror stay 1 over the leaf spring 4 and bracket 5, insert the positioning protrusion 16 into the positioning hole 2a, and then tighten the second screw 13.
is inserted into the second screw hole 15 and screwed into the female threaded portion 12, thereby screwing the mounting portion 3 and the bracket 5 together using the second screw 13. By this screwing, the bracket 5 is drawn toward the mounting part 3, the engagement shoulder part 11 is pressed against the engagement spring piece 7, and the mounting part 3 is pressed against the vehicle body plate 2, and the mirror stay 1 is moved into the vehicle interior. Attached to plate 2. In addition, the first
When attaching the leaf spring 4 to the vehicle body plate 2 using the screw 9, the nut 10 can be omitted by using a socket screw in the screw hole of the vehicle body plate 2, or by using a tassel pin screw for the first screw 9. Can be done.

In this way, the mirror stay 1 is securely attached to the vehicle body plate 2 via the bracket 5 and leaf spring 4.
If a large external force is applied to the mirror stay 1 for some reason, the engagement spring piece 7 will deform and become misaligned with the engagement shoulder 11, which will eventually cause the engagement spring piece 7 and the engagement shoulder 11 to become misaligned. The engagement is disengaged, the bracket 5 comes off from the leaf spring 4, and the mirror stay 1 falls off. The magnitude of the external force that causes the mirror stay 1 to fall off is determined by the engagement strength between the engagement spring piece 7 and the engagement shoulder 11, so the dimensions, shape, material of the leaf spring 4, etc. All you have to do is select it appropriately.

Note that when the external force is small and the mirror stay 1 is lifted to such an extent that it does not fall off, the engagement spring piece 7 is tapered, so the external force is removed and the engagement shoulder is lifted due to the taper action. 11 is pushed back and automatically returns to its original state, and the attachment angle of the mirror stay 1 to the vehicle body does not remain unchanged.

(Effects of the invention) As described above, the present invention engages the engagement shoulder of the bracket with the engagement spring piece of the leaf spring attached to the vehicle body, and attaches the mirror stay to this bracket. The bracket is designed to come off the leaf spring in response to the above external force, and has the advantage of being simple in structure, with a small number of parts, easy to manufacture, and easy to assemble.
