The present invention relates to a commercially available back-mirror, to be more specifically configured to be able to be folded toward the vehicle body if necessary to configure the rotating part of the back-miller.

In general, in the case of large vehicles such as trucks and buses, it is common to install the back-mirror in a state of protruding largely to the outside using a support to secure a wider rear view unlike a passenger car.

However, such a commercial vehicle's back miller has the following disadvantages because of its large body size.

In other words, when driving down a narrow alley or the like, the car may not be able to exit due to the surrounding facilities, or even in a large parking lot, it may be difficult to turn due to temporary interference with other large cars next to it. There is a need to fold the back mirror towards the body.

Therefore, the present invention has been devised to solve the various problems as described above, the main object of the invention is to fold the back mirror of the commercial vehicle to the body to widen the radius of rotation, and on the other hand the back mirror during long parking The purpose is to fold and protect.

And the characteristic configuration for this is the conventional commercial vehicle back miller in which the upper end of the U-shaped support with a miller on the suspension is mounted on the upper side of the body as a bracket, and the lower side is mounted on the lower side of the body as another bracket. The upper hinge mechanism is installed between the upper end of the c-shaped support and the extension shaft, and the lower hinge mechanism is installed between the lower end of the c-shaped support and the bracket so that the c-shaped support can rotate. In particular, the upper and lower hinge mechanism is connected to the upper or lower end of the U-shaped support, the shaft portion extending downward, the screw portion of the lower end of the shaft portion, the hinge shaft consisting of a ball installed in the spring on the shaft side, and the above-described extension The ball of the hinge shaft is fixed on one side or a bracket, and consists of a shaft bearing having a plurality of position grooves on one side of the shaft hole. Rotation is suppressed when each is attached to the position groove on the bearing.

Hereinafter, the detailed configuration and effect of the present invention according to the accompanying drawings.

Figure 1 is a front perspective view of a commercial vehicle showing the installation state of the present invention, Figure 2 is a front view showing the entire back miller of the present invention, the back mirror (1) and the U-shaped support (2) attached to the miller, and the upper and lower Hinge mechanisms 3a, 3b and extension pieces 3 and brackets 4 connected to the upper side thereof, and another bracket 5 connected to the lower side can be seen.

At this time, the configuration of the upper and lower hinge mechanism (3a), (3b) is largely divided into a hinge shaft 31 and the bearing support 32, the hinge shaft 31 is the upper end 21 of the c-shaped support (2) Alternatively, the lower end 22 is fixed, and the bearing 32 is fixed on the upper extension 3 or on the lower bracket 5.

The hinge shaft 31 has a shaft portion 33 extending downward, and the side of the shaft portion is a ball 35 that is installed in the spring 34, the end of the shaft portion 33 is a screw portion 36 It is.

The bearing 32 has a shaft hole 37 perforated so that the shaft portion 33 is fitted therein, and a plurality of V-shaped position grooves 38, 39 are formed around the shaft hole 37. The nut 40 is provided below.

The following describes the operating state of the present invention configured as described above.

First, the upper and lower hinge mechanisms 3a and 3b of the present invention should be assembled at the same time.

That is, both the upper and lower hinge mechanisms 3a and 36 insert the respective hinge shaft 31 shaft portions 33 into the shaft holes 37 of the bearing 32 from above, and the nut to the threaded portion 36 from below. Tighten (40) to fix.

After assembling in this manner, the upper bracket 4 is fixed to the upper side of the vehicle body, and the lower bracket 5 is fixed to the lower side of the vehicle body.

In the above state, the angle of the usual (when driving) U-shaped support 2 is positioned forward as shown in FIG.

At this time, the ball 35 of the upper and lower hinge mechanisms 3a and 3b will be seated in the front position groove 39 as shown in FIG. It is fixed as.

On the other hand, if the radius of rotation should be a little larger or if you want to fold the back-mirror rotate the angle of the c-shaped support (2) toward the vehicle body.

At this time, the ball 35 of the upper and lower hinge mechanisms 3a and 3b will be seated in the position groove 38 on the left side, as shown in FIG. 3, so that the back mirror does not move close to the vehicle body.

The structure as described above is an embodiment of a state in which the U-shaped support (2) is artificially manipulated and used, and further, after forming the worm gear on the outer peripheral surface of the hinge shaft 31, the worm of the motor shaft placed on the extension piece If you install the drive means by additionally connected to this, it is also possible to automatically operate the folding of the back miller from the driver's seat.

As described in detail above, the present invention provides a conventional back miller, which is fixed because the hinge mechanisms 3a and 3b are installed at the upper and lower ends of the c-shaped support 2 so that the position of the back miller 1 can be artificially adjusted. Unlike the narrow turning radius of the car body can be folded to the car body to prevent interference, as well as close to the car body when parking for a long time is a very useful invention that can protect the back miller like a compact car.

Claims (2)

The top 21 of the c-shaped support 2 with the mirror 1 on the suspension is mounted on the upper side of the vehicle body as the extension piece 3 and the bracket 4, and the bottom 22 is another bracket 5.
