Description

[Detailed Description of the Invention] The present invention relates to a door mirror for an automobile.

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, the mirror body is elastically supported by the mirror base fixed to the driver's cab wall, and the structure is such that it can tilt when external force is applied. Because the aircraft is equipped with springs, highly specialized skills are required to install them, making it difficult 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 door mirror with a shock absorbing mechanism. In the figure, the upward direction is the forward direction of the vehicle.

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 can rotate in the direction of arrow A about the rear shaft 8 from the illustrated state. The mirror body 3 is rotatably supported on the free end side of the hinge member 7 by a front shaft 9. 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. One possible method for attaching one end of the tension spring to the mirror base 2 is to attach it to the mirror base 2 with a pin 12 via a spring connection link 11.

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 Although it is convenient because the mirror 4 is placed close to the vehicle body and is covered by the mirror body 3, there are technical difficulties as described below.

In order to bring the mirror body 3 into contact with the mirror base 2 and maintain a normal posture in the normal use state of the door mirror (FIG. 2), the tension spring 10 must be made quite strong. Therefore, a large amount of force is required to tilt the mirror body 3 rearward as shown in FIG. 3, and if an operator attempts to do this by hand, a large amount of effort must be expended. Moreover, a strong locking device must be used to hold the mirror body 3 in this tilted position.

The present invention was devised in view of the above circumstances, and allows the mirror body to be held in a tilted position with a simple configuration, and furthermore, the operations to put the mirror body in the tilted position and restore it to the normal operating position are quick and easy. The purpose of the present invention is to provide a door mirror for an automobile that can be used for various purposes.

The above-mentioned problems with the door mirror configured as shown in Figure 2, namely (a) the need for a large amount of force to operate the tilting operation, and (b) the need for a strong locking device to maintain the tilted position, are as follows: This is directly caused by the strong biasing force of the tension spring 10, so the present invention is configured as described below to easily reduce the rotational force of the mirror body 3 due to the tension of the tension spring 10. The data can be deleted and restored at will by simple operations. This facilitates the tilting operation of the mirror body and makes it possible to maintain the tilted position using a simple locking tool.

In order to achieve the above object based on the above basic principle, the present invention forms a hinge member interposed between a mirror body and a mirror base, and connects the above hinge member to the mirror base with a hinge pin. An arm-shaped spring hook is formed on the free end side of the hinge member, and this spring hook is rotatably supported on the mirror base coaxially with the hinge pin, and The present invention is characterized in that it includes means for fixing the spring hook to the mirror base.

Next, an embodiment of the present invention will be described with reference to FIGS. 4 to 9.

FIG. 4 is a cross-sectional view showing the vicinity of the hinge member 7 of the remote control type door mirror with shock absorbing mechanism shown in FIG. be. Figure 5 shows the above spring hook 13.
FIG.

The spring hook 13 is provided with a bearing hole 13a that fits into the rear shaft 8, which is the hinge pin of the hinge member 7 mentioned above, so that it is rotatably supported by the rear shaft 8. In addition, a through hole 13b for hanging a spring is provided near the free end. In this embodiment, two through holes 13b are provided so that two tension springs are used. When the present invention is actually applied, an appropriate number of through holes are provided depending on the number of tension springs. In short, the spring hook according to the present invention has one end of a tension spring at the free end of an arm rotatably supported by a shaft (in this example, rear shaft 8) functioning as a hinge pin of hinge member 7. The structure shall be such that it can be attached.

Hole 13c for mounting screw in spring hook 13
This spring hook 13 is fixed to the mirror base 2 by drilling a hole and inserting a mounting screw 14 therethrough. The door mirror of this embodiment has the hinge member 7 interposed between the mirror body 3 and the mirror base 2 as described above, and is rotated to the mirror base 2 by the rear shaft 8 which is the hinge pin of the hinge member 7. The mirror body 3 is rotatably supported on the free end side of the hinge member 7, and an arm-shaped spring hook 13 is formed separately from the hinge member 7. The spring hook 13 is rotatably supported on the mirror base 2 coaxially with the rear shaft 8, and is provided with a mounting screw 14 for fixing the spring hook 13 to the mirror base 2.

In the door mirror configured as described above, when the mounting screw 14 is removed, the spring hook 13 rotates around the rear shaft 8 and comes into contact with the hinge member 7, as shown in FIG. The tension of the shock spring 10 is no longer applied. Therefore, the mirror body 3 is not subjected to any rotational force and is in a state where it can freely rotate about the rear shaft 8 together with the hinge member 7 and the spring hook 13. FIG. 7 shows a perspective view of this state. Reference numeral 2a designates a tapped hole provided in the mirror base 2 in order to screw the aforementioned mounting screw 14 into the mirror base 2.

As mentioned above, when the mirror body 3 no longer receives the rotational force from the tension spring 10, the operating force required to tilt it into the tilted position becomes lighter, and a simple locking tool is sufficient to hold it in the tilted position. . 15 and 16 are brackets with holes formed integrally with the mirror body 3 and mirror base 2, respectively;
Reference numeral 17 is a U-shaped lock bar formed to match the above-mentioned holed bracket. In this way, a practically sufficient locking effect can be obtained with a small and lightweight locking tool.

As can be easily understood from the above operation, when the spring hook 13 is fixed to the mirror base 2 with the mounting screw 14, the mirror body 3 is biased by the tension spring 10 and becomes in a state where it can exert a buffering function. When the screw 14 is removed to allow the spring hook 13 to rotate freely relative to the mirror base 2, the rotational force applied to the mirror body 3 by the tension spring 10 disappears, making it impossible to tilt the mirror body 3. becomes easier, and
It becomes easier to maintain a tilted posture.

When attaching and detaching the above-mentioned mounting screws 14, the mirror body 3 is tilted forward as shown in FIG. FIG. 9 is a perspective view of this state.

In this state, the distance between the tension spring 10 and the front shaft 9 becomes very short, so no large force is required to hold the mirror body 3 in this position. The tension of the tension spring 10 causes the spring hook 13 to rotate in a direction approaching the mirror base 2, so that in this state the mounting screw 14 can be easily attached and detached.

10 to 12 show an embodiment different from the above. In this embodiment, the previously explained spring hook 13 is divided into two spring hooks 18 as shown in Fig. 10. This spring hook 18 has a bearing hole 18a to be fitted onto the rear shaft 8, a through hole 18b for hanging the tension spring 10, and a hole 18c for inserting the mounting screw.
11 and 12, it can be incorporated in a remote control door mirror with a shock absorber mechanism, similar to the spring hook 13 of the previous embodiment, and the same effects as those of the previous embodiment can be obtained.

Due to the functions described in detail above, when the present invention is applied, the mirror body can be held in a tilted position with a simple configuration, and the operations to bring the mirror body into the tilted position and restore it to the normal operating position can be performed quickly. It can be done easily.
