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, in order to reduce the impact and reduce damage to the external object and the door mirror itself, a door mirror with a shock absorbing mechanism has been put into practical use in which the mirror body of the door mirror can be elastically tilted. .

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 in order to have a structure that can be tilted when external force is applied, a spring is installed inside. Because of this, highly specialized skills are required to install the door mirrors, 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 Figure 1.
Since sea transport and other transportation were carried out with the parts sticking out, transportation 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 can rotate in the direction of arrow A from the illustrated state. The above hinge member 7
A mirror body 3 is rotatably supported by a front shaft 9 on the free end side of the mirror body. 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 supported as described above comes into contact with the mirror base 2 and maintains 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 is capable of reliably holding 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. It is an object of the present invention to provide a tilted posture holding device that is easy to operate to restore the posture.

In order to achieve the above object, the present invention forms brackets each having an approximately 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.

(d) A portion of at least one of the parallel portions is pressurized and deformed in a direction perpendicular to the axis so that its maximum diameter portion has an interference with respect to the substantially perpendicular hole.

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. , anterior axis 9
and the tension spring 10 as shown in FIGS. 2 and 3.
The components are the same or similar to those described with reference to the figures.

In this embodiment, the tension spring 1
0 to the mirror base 2, a hole 20a for spring hanging is provided in the bracket 20, and one side of the bracket 20 is attached to the mirror base 2 using the rear shaft 8. A screw hole 20b is provided near the opposite side, and the mirror base 2 is attached to the mirror base 2 using a mounting screw 21. Reference numeral 22 indicates a tapped hole provided in the mirror base 2 for a mounting screw. With this configuration, when the bracket 20 is fixed to the mirror base 2 with the mounting screw 21, the biasing force of the tension spring 10 acts, and when the mounting screw 21 is removed, the bracket 20 is fixed to the mirror base 2. The mirror base 2 rotates in a direction away from the mirror base 2 and enters the state shown in FIG. 4, and the biasing force of the tension spring 10 is separated from the mirror base 2. Therefore, when the mounting screw 21 is removed as shown in this figure, the mirror body 3 is in a state where it can freely rotate around the rear shaft 8, and it can be tilted backward with a light force. Since the rear tilted posture can be maintained using a locking device, this embodiment provides a simple locking means as described below.

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.

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 substantially U-shape. The distance L between the U-shaped parallel rod-like ends 18a and 18b is the same as the distance between the pin holes 14 and 16 in the backward tilted position as shown in the figure.

A curved part 18c that is convex upward is formed at the upper part of the rod-shaped part 18a, which is one of the parallel rod-shaped ends 18a and 18b. When implementing the present invention, the shape and dimensions of this curved portion can be set arbitrarily. For example, one idea is to form it into a semicircular arc shape or a ring shape with a radius of curvature of 4 to 10 mm. When formed in this way, it is convenient to hang the index finger on this curved portion or insert a screwdriver through it as described later.

Then, the rod-shaped portion 1 corresponding to the lower part of the curved portion 18c
A force in a direction perpendicular to the axis is applied to two locations of 8a using a press or a hammer to cause local plastic deformation, thereby forming pressurized deformation portions 18d and 18e.

The lower half of the rod-shaped portion 18a, in which the pressurized deformation portions 18d and 18e have been formed as described above, is attached to the bracket 15.
A partially enlarged cross-sectional view of the pin inserted into the pin hole 14 is shown in FIG. 5, and a cross-section taken along line XX of the same figure is shown in FIG. The rod-shaped portion 18a, which has not been deformed by pressure, has a circular shape that slides into the pin hole 14 (shown by a phantom line). The cross section of the pressurized deformation portion 18d has a shape similar to an ellipse, the dimension r ₁ corresponding to its short axis is smaller than the diameter r of the rod-shaped portion 18a, and the dimension r ₂ corresponding to its major axis is the rod-shaped portion. It is larger than the diameter r of 18a.

In this embodiment, the dimension r ₂ corresponding to the long axis is slightly larger than the inner diameter r ₃ of the pin hole 14 to provide an appropriate tightening margin. The above appropriate tightening allowance is
This refers to a tightness that allows for easy press-in and removal by hand, and does not easily slide due to vibration or inertial force.

Although not shown, the upper pressure deformation part 18e is configured to give a slightly larger plastic deformation than the lower pressure deformation part 18d, and the dimension corresponding to the large diameter prevents the pin from passing through the hole 14. do. Further, when implementing the present invention, the upper pressure deforming portion 18e may be omitted.

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. the lower pressurized deformation part 18d is inserted into the bracket 1.
When the mirror body 3 is pushed in until it passes through the pin hole 14 of No. 5 and the upper pressurized deformation portion 18e hits the entrance of the pin hole 14 and is prevented from sliding, the mirror body 3 is held in a tilted position. Ru. Since the pressurized deformable portion 18d of the lock bar 18 is press-fitted into the pin hole 14, there is no risk of the lock bar 18 coming off even if subjected to vibration or inertial force. Further, even if the door mirror is turned upside down during transportation or handling before it is attached to the vehicle body, there is no risk of it falling off due to its own weight.

In order to restore the door mirror held in the tilted position to its normal operating state, it is sufficient to place a fingertip on the curved portion 18c and pull it upward. At this time, if a rod-shaped tool such as a screwdriver is inserted into the curved portion 18c and a lever is used, it can be removed with even less force.

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.
