Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an inverted V in which a board fitted with a rearview mirror stay is crimped and fixed to a seat plate across the outer panel of an automobile body, and is held by a coil spring on the seat plate side.
This device relates to a back mirror mounting device in which a letter-shaped locking piece is engaged with a movable hook suspended from the bottom of the stay.In particular, the locking piece is inserted into the insertion hole of the inverted V-shaped locking piece when the stay is removed. By forming a temporary fixing ridge and a flange for preventing the spring assembly from scattering, the rear view mirror can be assembled and removed accurately and easily.

Among tilting rear mirrors, one is already known that is intended to be installed or removed in one-touch manner without using tools such as spanners when attaching the stay part of the mirror to the vehicle body (Jikkosho).
53-11940). In this case, a hook rod, which has a connecting hook portion on the upper side and a temporary hook portion on the lower side, is attached with a coil spring constantly biased downward. A fixed connecting pin attached to the bottom surface of the stay is engaged with the hook part, and the lower hook part is configured to be hooked to an engaging ridge provided on the seat plate.

At first glance, this precedent example appears to work smoothly, but when we actually tried making a prototype and experimenting with it, it became clear that we could not expect smooth operation due to the following drawbacks. Ta. In other words, as shown in Fig. 8, when removing a mirror once attached, the mirror stay S must be tilted backwards using the rear end A of the stay as a fulcrum, but even if the stay is tilted, this stay cannot be removed. The hook rod F connected to the seat plate _C is simply lifted up, and the lower hook portion F 2 of the upper and lower hook portions F ₁ F ₂ formed on this hook rod is caught on the ridge D provided on the seat plate C. Instead, it only has the effect of simply lifting the hook rod against the elasticity of the spring E. Therefore, in order to hook the hook part F ₂ on the ridge D, it is necessary to disengage the base of the stay S and the board B and forcefully engage the hook part F ₂ with the ridge D. In that case, the elasticity of the coil spring E is effective, so the stay is pulled downward,
I can't get it to engage as I want. Furthermore, if the hook rod F is disengaged from the protrusion D before it is completely engaged with the stay side, the spring assembly immediately flies off, resulting in poor workability.

Here, the present invention provides a hook to be provided at the bottom of the stay, which is swingably hung from the stay, and correspondingly, an inverted V-shaped locking piece is elastically held on the back surface of the seat plate. The above-mentioned drawbacks can be solved by engaging the upper end portion with a swingable hook, and further providing a flange for temporary fixing and a ridge for preventing the spring assembly from scattering within the insertion hole surface of the inverted V-shaped locking piece. This eliminates all of the above.

Accordingly, in the present invention, before assembling the rearview mirror to the automobile body, the two halves of the inverted V-shaped locking piece are temporarily secured by the ridge formed in the insertion hole of the seat plate.
Next, after combining the base plate and the seat plate, tilt the stay to the left or right to engage the movable hook on the lower side of the stay with the locking piece, and then remove this locking piece from the temporary flange. This makes it possible to easily attach the rearview mirror with a light force using a lever. In addition, when removing it after assembly, tilt the stay to the right or left and hook the engaged movable hook and locking piece to the temporary fixing ridge, thereby making it free. The movable hook can be removed from the locking piece, and even if the locking piece should come off, the second projecting edge prevents the spring assembly from flying off, allowing the mirror to be assembled or removed. It is designed to be easily performed.

The present invention will now be described in detail with reference to the drawings.

In the figure, 1 is a stay for a rear view mirror, 2 is an outer panel of a vehicle such as the front of a car, 3 is a board on which the stay 1 is fitted, 4 is a seat plate that is crimped and fixed to the board 3 on the lower surface of the outer panel of the vehicle body 2, and 5 is a seat plate. A coil spring, 6 is a hook pivotally attached to the lower part of the stay 1, and 7 is an inverted V-shaped locking piece hung between the coil spring 5 and the hook 6, and has elasticity made of steel wire. It is possible to use a hook spring.

A back mirror M is attached to the upper part of the main body of the stay 1, and the lower peripheral edge is fitted into a groove 8 formed around the base plate 3. Further, as shown in FIG. 1, a movable hook 6 is vertically disposed approximately in the center of the lower part of the stay 1, using a pin 23, so that the movable hook 6 can swing in a direction perpendicular to the longitudinal direction of the lower part of the stay. Further, as shown in FIGS. 1 and 2, the substrate 3 is provided with an insertion tube 11 and a protrusion 12 that are formed downward. It has a cut 13, and several (two in the figure) narrow cuts 14 extending approximately half the length of the cylindrical part, to avoid contact with the upper end portion of the hook spring when temporarily fixing the hook spring 7, It also has a relatively wide notch 15 that provides a "relief" without hindering the swinging of the stay side hook 6.
On the other hand, the seat plate 4 combined with the substrate 3 is formed with an insertion hole 16 into which the insertion tube 11 is fitted and an insertion hole 17 into which the protrusion 12 is inserted. Note that two mounting holes are bored in the vehicle body outer panel 2 of the above-mentioned automobile, through which the insertion tube 11 and the protrusion 12 of the board 3 are inserted.

Further, a coil spring 5 is arranged on the outside of the lip 19 of the insertion hole 16 toward the bottom of the seat plate.
The hook spring 7 keeps the coil spring 5 in a compressed state at all times. The hook spring has an inverted V-shaped engagement portion 9 at its upper end that engages with a hook 6 suspended on the stay side, and hooks at both lower ends that engage the washer 20 of the coil spring 5 in the diametrical direction of the lower end. It has parts 10, 10. The lower end of the coil spring 5 is supported by a washer 20 having an elongated hole 21 in the center.
1, insert the hook spring 7 into the coil spring and make it stand up in the hollow space of the coil spring.
0,10 on the lower end of the washer 20 in the diametrical direction,
An engaging portion 9 at the upper end is hooked onto a movable hook 6 on the stay side.

An inverted V-shaped locking piece 7 is provided within the plane of the insertion hole 16.
A temporary fixing ridge 18 extends from the seat plate 4 side,
In addition, a second protrusion 18 for preventing scattering is opposite to this protrusion 18 and has a step with the protrusion 18.
A also extends from the seat plate side.

As mentioned above, since there is a protruding edge 18 in the surface of the insertion hole, it is possible to temporarily attach the hook spring 7, which is a locking piece, by temporarily fixing it, and to easily perform the installation or removal work of the installation device. However, if the temporarily fixed state should come off, there is a risk that the spring assembly, including the coil spring 5, washer 20, and hook spring 7, may all be scattered due to the elasticity of the coil spring 5. Therefore, the insertion hole 1 is placed opposite the temporary fixing protrusion 18.
A protruding edge 18a for preventing scattering is formed in the plane of 6. Since the two protruding edges 18 and 18a are arranged at opposite positions with a difference in level, they do not interfere with the locking of the hook spring 7, and the protruding edges 18 serve as a temporary fixing for a normal hook spring, so that it can be easily secured in the event of a temporary fixation. Even if the stopper comes off, it will be caught on the second protruding edge 18a, preventing the various members of the spring assembly from flying off, allowing for smooth installation and removal operations.

To assemble the mirror mounting device of the present invention, as shown in FIGS. 3 to 5, the coil spring 5 is placed in the lower part of the insertion hole 16 of the seat plate 4, and the hook parts 10, 10 of the hook spring 7 are is placed on the washer 20 of the coil spring 5, and the vicinity of the upper end of the hook spring is placed on the curved portions 22, 22 of the ridge 18 of the insertion hole 16 and temporarily secured. After doing this, the seat plate 4 is positioned at the lower part of the mounting hole of the car body outer plate 2, and the insertion cylinder 11 and the protrusion 12 of the base plate 3 into which the stay 1 is fitted from above the car body outer plate 2 are placed.
are press-fitted into the insertion holes 16 and 17 of the seat plate 4 through the mounting holes of the outer panel of the vehicle body, respectively. Insertion tube 1
The lower end of the seat plate 1 forms a bulge or undercut 13, so that it is firmly fitted into the insertion hole 16 of the seat plate and fixed. Next, hold the stay 1 supporting the mirror M, tilt it to the left or right as shown in FIG. , raising the hook spring to an upright position. The hook spring has its upper end engaging portion 9 hooked to the movable hook 6 at the bottom of the stay, and its lower end hooked to the coil spring, so that the stay 1 can be mounted in the correct position by the elasticity of the coil spring. Since it is installed in this manner, even if the rearview mirror M collides with a human body or the like during use, the stay supported by the coil spring will not tilt and injure the human body or the like. Further, when the mirror is to be removed, the stay 1 is tilted in the opposite direction from when it was attached, the hook spring 7 is temporarily fixed to the ridge 18, and then the seat plate 4 and the base plate 3 are disengaged.

Fig. 6 shows the operating state of the movable hook 6 and the hook spring 7 during assembly in the above mounting device. ○ As shown by the chain line in A, hook the hook 6 attached to the stay side onto the engaging part 9 of the hook spring 7 which is temporarily fixed, and
While lifting the bottom surface of the stay a little upwards, tilt it to the left as shown in the symbol ○B, use a lever to remove the temporary fixing with light force, and then raise the stay to its normal position (see the symbol ○C). A back mirror can be installed. Further, FIG. 7 shows the operating state of the hook 6 and the hook spring 7 when the stay 1 in an upright state is tilted to the right and removed. In other words, when the stay 1 is erected in the normal position, the hook 6 is in the state of symbol ○C, but when the stay 1 is turned to the right and tilted almost horizontally, it becomes the state of ○2, which compresses the coil spring 5. While doing so, raise the hook spring 7. Next, when the stay 1 is pulled in the opposite direction while bringing the hook spring 7 engaged with the hook 6 toward the protruding edge 18 side, the state becomes ○ho as shown by the solid line, and the two-mata part near the upper end of the hook spring 7 is pushed out. Hang it around the edge 18 and temporarily secure it. After temporarily fixing it like this, hook 9
The stay 1 can be easily removed by rotating it clockwise to disengage it from the hook spring 7.

As described above, according to the present invention, attachment and detachment of the rearview mirror to the outer panel of the automobile body can be completed by manual operation without using any special tools. In other words, the back mirror can be easily and reliably attached by crimping the base plate and the seat plate with the outer skin of the vehicle in between, tilting the stay, and hooking the temporarily fastened locking piece to a movable hook that is swingably provided on the stay side. can be attached and quickly removed by reversing the operation. In addition, a hook spring, which is an inverted V-shaped locking piece, is elastically attached by a coil spring on the underside of the seat plate, and before assembly, it is temporarily fixed to a temporary fixing ridge formed in the insertion hole of the seat plate. By press-fitting the stay from above and tilting it to the left or right, the movable hook pivoted to the stay side can be swung and accurately engaged with the hook spring to firmly fix the stay. It is. Furthermore, since it has a second protrusion separate from the temporary fixing protrusion, even if the temporary fixing comes off, the hook spring will be caught on the second protrusion, thereby preventing each member of the spring assembly from flying away. It can be prevented. Since the second flange is provided in a position opposite to the flange for temporary fixing, it does not get in the way of locking and unhooking the hook spring, making it possible to reliably assemble and remove the rearview mirror from the vehicle body. It has a calming effect.
