Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for holding a mirror body of a door mirror with a shock absorbing mechanism in an inclined position with respect to a mirror base.

A door mirror for an automobile is mounted on the outside of a wall of a driver's cab, and as shown in FIG. 1, a mirror body 1 protrudes by a dimension l beyond the maximum width of the vehicle body.

For this reason, there is a risk that the vehicle will collide with an external object while the vehicle is running, and there is also a problem that, during transportation such as shipping, an extra space corresponding to the above-mentioned l dimension will be occupied.

When a door mirror collides with an external object, the shock absorber has a structure that allows the mirror body of the door mirror to tilt elastically in order to reduce the impact and reduce damage to the external object, the door mirror, and the wall of the driver's cab in which the door mirror is attached. Door mirrors with mechanisms have been put into practical use.

On the other hand, in order to reduce the space occupied during shipping, some vehicles have conventionally been loaded with door mirrors not installed or with door mirrors removed, and then installed the door mirrors after landing.

However, in the above-mentioned door mirror with a shock absorbing mechanism, an internal spring is installed in order to elastically support the mirror body against the mirror base fixed to the driver's cab wall and to create a structure that can be tilted when external force is applied. Because of this, highly specialized skills are required to install them, and it is not easy to install the door mirrors after landing.

Furthermore, door mirrors equipped with remote control means require more advanced specialized skills and are therefore difficult to install after landing.

Due to the above circumstances, in automobiles equipped with door mirrors with a shock absorbing mechanism, the mirror body 1 of the door mirror is generally attached to the outside of the vehicle body as shown in Fig. 1.
Since sea transport and other transport were carried out with the parts sticking out, transport costs increased and it was uneconomical.

FIG. 2 shows a plan view of an example of a remote control type door mirror with a shock absorbing mechanism. In the figure, the upward direction is the forward traveling direction of the automobile.

2 is a mirror base fixed to the wall of the driver's cab of the automobile, and 3 is a mirror body. The mirror 4 is fixed to a mirror housing 5, and the mirror housing 5 is rotatably supported by the mirror body 3. 6 is an electric drive unit for remotely controlling the mirror housing 5, and 6a is a wire protection tube.

The mirror body 3 is attached to the mirror base 2 via a hinge member 7 as described below so that the mirror body 3 can be tilted freely both forward and backward with respect to the mirror base 2 in the traveling direction of the automobile.

A hinge member 7 is rotatably supported on the mirror base 2 by a rear shaft 8. The hinge member 7 rotatably supports the mirror body 3 with a front shaft 9 on the free end side of the hinge member 7 which can rotate in the direction of arrow A from the illustrated state. The mirror body 3 can rotate in the direction of arrow B from the illustrated state.

A tension spring is installed between the mirror body 3 and the mirror base 2 so that the mirror body 3 and the mirror base 2 which are supported as described above are brought into contact with each other to maintain a normal posture protruding to the side of the vehicle body as shown in the figure. 10 is interposed and engaged and biased in the direction of arrow C. Reference numeral 11 is a link for engaging the tension spring 10, and reference numeral 12 is a pin that pivotally connects the link 11 to the mirror base 2.

The door mirror shown in Figure 2 configured as above is
When the mirror body 3 receives an external force in the direction of arrow D, the hinge member 7 rotates in the direction of arrow A around the rear shaft 8, and the mirror body 3 tilts backward together with the hinge member 7 as shown in arrow E. Alleviates the impact of external forces. FIG. 3 shows a state in which the mirror body 3 is tilted rearward as indicated by arrow E.

When the mirror body 3 receives an external force in the direction of arrow F, the hinge member 7 rotates around the front shaft 9 in the direction of arrow B, and the mirror body 3 tilts forward as shown by arrow G to alleviate the impact of the external force.

When shipping the door mirror configured as described above, by tilting the mirror body rearward and maintaining this position as shown in FIG. 3, the extent to which the door mirror projects outward from the vehicle body is reduced, and This is advantageous because it allows the mirror side to be close to the vehicle body and is covered by the mirror body, but conventionally there has been no suitable means for holding the mirror body in a rearwardly tilted position.

The present invention was developed in view of the above circumstances, and it is possible to reliably hold the mirror body of a door mirror with a shock absorbing mechanism in a tilted position backwards with respect to the mirror base, and also allows the mirror body to be held in a tilted position and to operate normally. Easy to operate to restore posture.
It is an object of the present invention to provide a tilting posture holding device with a simple configuration and low manufacturing cost.

In order to achieve the above object, the present invention forms brackets each having a substantially vertical hole in the mirror body of a door mirror with a shock absorbing mechanism and the mirror base that supports the same, and separately from the above, The locking tool is characterized by the following structure.

(a) The above-mentioned locking tool has rod-shaped both ends, and these ends are formed parallel to each other.

(b) The diameter of the above-mentioned parallel rod-shaped portion is formed to a size that allows it to fit into the substantially vertical hole provided in the above-mentioned bracket.

(c) The spacing between the parallel rod-shaped portions is approximately equal to the spacing between the holes in the brackets fixed to both of the members, respectively, when the mirror body is tilted backward with respect to the mirror base.

Next, an embodiment of the present invention will be described with reference to FIG. This figure is a perspective view of a door mirror with a shock absorbing mechanism equipped with an embodiment of the tilting posture holding device according to the present invention, in a state where it is tilted backward, and shows a mirror base 2, a mirror body 3, a hinge member 7, and a rear shaft 8. , the front shaft 9, the tension spring 10, the link 11, and the pin 12 are the same or similar components to those described with reference to FIGS. 2 and 3, and 13.
is a bracket formed on the mirror base 2 to support the pin 12.

Forming a bracket 15 with a pin hole 14,
This bracket 15 is formed integrally with the mirror body 3 so that the pin hole 14 is oriented substantially vertically.

Similarly, a bracket 17 with pin holes 16 is formed and fixed to the mirror base 2 with the pin holes 16 oriented substantially vertically. In this embodiment, the above-mentioned bracket 17 is molded from synthetic resin so as to be integrally connected with the mirror base 2 and the bracket 13.

Separately from the above, a lock bar 18 is formed by bending a wire having a diameter that fits into the pin holes 14 and 16 into a U-shape. U-shaped parallel ends 18
The distance L between a and 18b is set to be the same as the distance between the pin holes 14 and 16 in the backward tilted position as shown in the figure.

When applying this invention in practice, the lock bar 18
The handle 19 does not necessarily have to be formed by bending a wire into a U-shape as in this example; for example, as shown in FIG. 5, the handle 19 may have pins 20 implanted at both ends thereof. In this case, the pin 20 has a diameter of 2
The pins 20 are made parallel to each other, and the distance L between the two pins is set to be the same as the distance L between both ends of the lock bar 18.

As mentioned above, the locking device according to the present invention (a) has rod-like ends on both ends, and these ends are parallel to each other, and (b) the diameter of the rod-like portions is the same as that of the mirror body. and (c) the distance between the parallel rod-shaped portions is such that when the mirror body is tilted backward with respect to the mirror base, , are formed to be approximately equal to the spacing between the pin holes of the bracket fixed to both of the above members.

2a is a recess formed to accommodate the bracket 15 when the mirror body 3 is in the normal operating position.

Since the device of the present invention is constructed as described above, when the mirror body 3 is tilted backward as shown in FIG.
a, 18b can be inserted into the pin holes 14, 16 to quickly and easily lock the mirror body 3 in the tilted position, and by removing the lock bar 18 from the pin hole, the normal operating state can be quickly and easily restored. can be restored to.

Since the pin holes 14 and 16 are provided almost vertically, even if severe vibration is applied to the door mirror held in a tilted position, the lock bar 18 receives a force in the direction of fitting into the pin hole due to its own weight. There is no risk of it falling off. In the present invention, the pin holes are provided almost vertically in order to prevent the locking device from falling off due to its own weight, so it does not need to be strictly vertical, but rather with a slight inclination. This does not preclude the attachment of

Due to the effects described in detail above, when the present invention is applied, it is possible to reliably hold the mirror body in the tilted position with a simple configuration and low manufacturing cost, and also to maintain the mirror body in the tilted position and to maintain normal operation. It is easy to restore the device to its working state.
