Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to protect against external forces exceeding a predetermined level in order to prevent danger to occupants when a vehicle suddenly stops or collides.
This invention relates to a detachable rearview mirror mounting mechanism.

[Prior Art] For example, as shown in FIG. 7, a removable rearview mirror for a vehicle is installed by attaching a set screw to a base stay 12 via a stay 13 and a disc spring 14, which allow the mirror to be set rotatably with an appropriate torque. After being set in a removable manner using the user 15, it is attached to the base 11, which has been fixed in advance near the front edge of the vehicle windshield or the ceiling of the passenger compartment, using screws 16.

[Problem to be solved by the invention] In the above-mentioned conventional mounting structure, the falling mechanism is the disc spring 1 at the mounting part of the stay 13 and the base stay 12.
4 and set screw 15, there are restrictions on the setting position of the mirror, and as shown in FIG. It is necessary to arrange the base of the stay at a position upward from the line Z-Z in the direction of the arrow, and as a result, there have often been cases where the driver's view has to be obstructed.

The present invention aims to solve the above-mentioned problems and provide a rearview mirror mounting mechanism that is not subject to restrictions on the setting position and that can be easily incorporated into a vehicle.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses a U-shaped locking rod to attach a base stay that is slidably attached to a base.
That is, in a rearview mirror in which a base stay is interposed on the lower surface of a base fixed to the upper part of the windshield of a vehicle or near the front edge of the cabin ceiling, and a mirror support stay is removably attached; A rail-type sliding portion having a groove is provided to slidably insert the base stay in the longitudinal direction of the vehicle; several through holes are provided in the lateral direction in the opposing guide grooves; one through hole is inserted from one side of the base. A locking rod is inserted through the hole toward the other through-hole and elastically abuts against the upper surface of the base stay between the opposing through-holes to stop the base stay from sliding.

The rail-type slide part has a notch in the center of the guide groove that allows the base stay to be inserted from below the base. The locking rod has a U-shape that can be inserted into several through holes at the same time, and has knurling at the tip of each leg that is the parallel side of the U-shape. Further, the upper surface of the base stay is provided with a convex portion at the contact portion of the locking rod, and a groove for mounting the rod is formed at the top of the convex portion.

[Operation] When assembling to a vehicle, the base, into which the locking rod has been inserted in advance, is attached to the member to be attached using adhesive or the like. Next, insert the base stay with the stay set downward into the center notch of the rail-type sliding part of the base, and press it in the sliding direction while sliding further, so that the top surface of the base stay is elastically locked to the locking rod. It can be attached to the base. Furthermore, in response to the action of an external force, the stay falls off in response to the direction of the action or by a conventional falling mechanism, or the base stay falls off while sliding on the rail-type slide section.

[Example] An example will be described based on the drawings. FIG. 1 shows a side sectional view of the present invention, FIG. 2 shows a front view including a partial sectional view, and FIG. 3 shows an exploded perspective view.

FIG. 1 is a longitudinal sectional view of the present invention, and FIG. 3 is an exploded perspective view of the present invention. In a rearview mirror in which a mirror support stay 3 is removably attached via a base stay 2, a rail-type slide portion having opposing guide grooves 1a, 1a is provided on the lower surface of the base 1, and the base stay 2 is moved along the longitudinal direction of the vehicle. Insert it so that it can slide freely in the direction. The opposing guide grooves 1a, 1a are provided with several through holes 1d, 1d in the lateral direction, and the base 1
The base stay 2 is connected from one side through one through hole to the other through hole, and between the opposing through holes.
A locking rod 4 is inserted to resiliently abut on the upper surface of the base stay and restrain the slide of the base stay.

The guide groove 1a is provided with a central notch 1b as shown in FIG. 3, and a long groove 1 is provided on the outside of the guide groove 1a.
C and two sets of through holes 1d are provided, and a U-shaped locking rod 4, which will be described later, is inserted under pressure at right angles to the sliding direction.
It is fixed to the base 1 by the knurling 4a at the tip.

As shown in FIG. 4, the base stay 2 has a sliding portion 2 that slides into the guide groove 1a and has a notch in the center.
A is provided on both sides of the lower part. The lower surface of the base stay 2 is provided with convex portions 2c, 2c that abut against the leg portions 4b, 4b of the locking rod 4, and as shown in FIG. It is designed so that it can be inserted into the center notch 1b from below.

The engaging portion 2c is attached in a semicircular shape to the top ridgeline of a convex portion having tapered slopes 2e on both sides, as shown in A of FIG. 4, which is a perspective view from the bottom of the base stay 2. A groove 2d is provided. When the base stay 2 is installed on the base 1, the mounting groove 2d is disposed at an appropriate position on the lower surface of the base stay 2 with respect to the locking rod 4 that has been inserted into the base 1 and fixed in advance. When inserted into the central notch 1b of the guide groove of the base 1 from below and slid to either the left or right, the leg 4 of the locking rod 4
b, 4b elastically lock the mounting groove 2d via the tapered slope 2e of the convex portion 2c.

With the above structure, when installing the base 1, into which the locking rod 4 is inserted and fixed, is fixed to a member to be mounted, for example, the windshield 8, with an adhesive. Then, as shown in FIGS. 2 and 3,
While aligning the small protrusion 2f on the lower surface of the base stay 2 with the recess 3f on the upper surface of the stay 3, they are fastened and set using the disc spring 5 and the set screw 6.

As shown in FIG. 5, the base stay 2 with the stay 3 set above is inserted into the center notch 1b of the base 1 from below, and then the sliding part 2a is inserted to the left through the guide groove 1a. The leg portion 4b of the rod locks on the tapered slope 2e of the convex portion 2c.
When the locking rods are brought into contact with each other and then pressed further, the leg portions 4b of the locking rods are elastically locked in the grooves 2d, and the base stay 2 is attached to the base 1.

The locking rod 4 is connected to the base 1 and the base stay 2.
The locking rod 4 and the convex portion 2c are provided perpendicularly to the rail-type slide portion formed by the locking rod 4, and the locking rod 4 and the convex portion 2c are elastically locked, so that there is no play caused by vehicle vibration.

When an external force is applied to the rearview mirror having the above-mentioned mounting mechanism, depending on the mounting angle with respect to the vehicle traveling direction as shown in Figs. 6a and 6b, for example, in the case of the mounted member 8a having a shallow inclination angle as shown in Fig. 6a. The locking between the base stay 2 and the base 1 via the locking rod 4 is released, and the stay 3 slides along the rail type slide section with the base stay 2 and falls diagonally downward, as shown in Fig. 6b. In the case of the attached member 8b having a deep inclination angle, a falling mechanism provided between the stay 3 and the base stay 2 causes the base stay 2 to fall off while remaining on the base.

[Effects of the invention] Since the present invention has the above configuration, it has the following effects.

The present invention has a separate detachable rail-type slide section in place of the conventional detachment mechanism provided between the stay and the base stay, and has a large permissible angle distribution with respect to the line of action of external force, making it possible to set the mirror. There are no restrictions on the location, and it can be set anywhere, that is, in a predetermined location that does not directly affect the driver's visibility.

In addition, since the mounting means uses elastic locking instead of screws, there is no need to set up a cover to hide the mounting screws, making it easy to integrate into the vehicle. , it is possible to provide a compact and reliable rearview mirror mounting mechanism.

Since the guide groove of the rail-type slide part of claim 2 is provided with a central notch, the base stay can be inserted into the base from below with a wide working space relative to the mounting surface, and there are no restrictions on installation. There is no.

By using the U-shaped locking rod having the knurled tip of claim 3, it is easy to fix the rod to the base.

When the locking rod is engaged with the groove formed in the convex portion on the top surface of the base stay as in claim 4, the effect is that the locking rod can be made compact and fully functional compared to the linear sliding engagement or disengagement mechanism. has.
