Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement of a side mirror support structure that supports a side mirror disposed on one side in front of a windshield on the front side of a vehicle body.

[Technical background of the invention]

In general, vehicles such as trucks are provided with side mirrors 3 and 4 on both sides (driver's seat side and passenger's seat side) of a front windshield 2 in front of a cab (driver's cab) 1 on the vehicle body side, as shown in Figure 4. It is set up. In this case, for example, as a support structure for the side mirror 3 disposed on the driver's seat side, a vertical stay is disposed on one front side of the front windshield 2 and has both upper and lower ends fixed to the cab 1 side. 5 and a horizontal stay 6 whose one end is fixed to the intermediate part of the vertical stay 5 and whose other end extends toward the side of the cab 1, forms a support stay main body 7 of the side mirror 3. A configuration in which a side mirror 3 is fixed to the free end side of a horizontal stay 6 of the main body 7 is known. However, in the case of such a structure, for example, the width of the cargo box 8 connected to the rear of the cab 1 is a standard length (approximately
When the length was longer than 2.5 m), there was a problem that the rear view of the side mirror 3 was blocked by the cargo box 8.

Therefore, an overhang stay is provided which is arranged approximately parallel to the horizontal stay 6 of the support stay main body 7 and is slidably connected to the horizontal stay 6 via a connecting member, and a side mirror 3 is attached to the tip of the overhang stay. The rear view of the side mirror 3 is secured by securing the side mirror 3 and sliding the overhang stay laterally to an appropriate extended position. However, in this case, the rigidity of the support stay body 7 tends to be relatively weak, so the entire support stay body 7 may vibrate due to wind pressure acting on the side mirror 3 or transmission of vibration from the vehicle body while driving. I had an easy problem. Therefore, the mirror surface of the side mirror 3 is likely to vibrate, resulting in a problem that the side mirror 3 becomes difficult to see.

[Purpose of invention]

This idea increases the rigidity of the support stay body, reduces the vibration of the support stay body while driving, allows the side mirror to be held in an easy-to-see state, and allows for a simplified configuration of the side mirror. The purpose is to provide a support structure for

[Summary of the idea]

This idea consists of a vertical stay that is installed on one side of the front windshield at the front of the vehicle body, and has both upper and lower ends fixed to the vehicle body, and one end is fixed to the middle of the vertical stay and the other end is fixed to the middle of the vertical stay. The supporting stay body of the side mirror is formed by the sideways stay extending toward the side of the vehicle body, and the support stay body of the side mirror is formed by the sideways stay that is arranged substantially parallel to this sideways stay and is connected laterally to the sideways stay through a connecting member. In a device in which a side mirror is fixed to the tip of the overhang stay that is slidably connected, one end is the free end of the sideways stay, the other end is fixed to the vehicle body side, and the middle part The present invention is characterized in that a reinforcing stay for vibration isolation is fixed to the vertical stay.

[Example of idea]

1 to 3 show an embodiment of this invention. FIG. 1 shows the appearance of a cab (driver's cab) 11 of a vehicle such as a truck.
is the front windshield of Cab 11, 1
Reference numeral 3 denotes a side mirror disposed on one front side of the front windshield 12 (the side on the driver's seat side). As shown in FIG. 2, the support stay main body 14 of the side mirror 13 is disposed on one side in front of the front windshield 12, and the upper and lower ends of the support stay body 14 are fixed to the cab 11 side.
A horizontal stay 16 is formed with one end fixed to the intermediate portion of the vertical stay 15 and the other end extending toward the side of the cab 11. In this case, mounting portions 17 and 18 for screwing are formed at both ends of the vertical stay 15, and the upper mounting portion 17 is screwed to the cab 11 side via the upper bracket 19, and the lower mounting portion 17 is screwed to the cab 11 side via the upper bracket 19. The side mounting portion 18 is screwed to the cab 11 side via a lower bracket 20. Further, one end portion of the horizontal stay 16 is fixed to the intermediate portion of the vertical stay 15 by means such as welding.

On the other hand, the horizontal stay 16 of the support stay main body 14
An overhang stay 21 is arranged substantially parallel to the above.
This overhang stay 21 is connected to the horizontal stay 16 via a connecting member 22, and a side mirror 13 is fixed to the tip of this overhang stay 21. Furthermore, as shown in FIG. 3, this connecting member 22 is formed by a pair of insertion pipes 23a, 23b and a pair of clamping pieces 24a, 24b, and the horizontal stay 16 is inserted into one of the insertion pipes 23a. together with the other insertion pipe 2
3b with the overhang stay 21 inserted, both insertion pipes 23a, 23b are held by the clamping pieces 24a, 24b.
The structure is such that it is held between the two. and,
By loosening the clamping force between the clamping pieces 24a and 24b, the overhang stay 21 is held in a horizontally slidable state, and by increasing the clamping force between the clamping pieces 24a and 24b, movement of the overhang stay 21 is prohibited. It's getting old. Further, one end of a reinforcing stay 25 for vibration isolation is fixed to the free end of the horizontal stay 16 of the support stay main body 14 with a screw 26. This reinforcing stay 25 is formed of a single pipe material, and the other end of this reinforcing stay 25 is fixed to the vehicle body side by means such as screwing, and the middle of this reinforcing stay 25 is is fixed to the vertical stay 15 via a fixing bracket 27. Note that this fixed bracket 27
is formed by a first fixing plate 29 having a groove-shaped holding part 28 for holding the vertical stay 15 and a second fixing plate 31 having a groove-like holding part 30 for holding the reinforcing stay 25. These first and second fixing plates 29, 31 are tightened and fixed by tightening screws 32....

Therefore, in the case of the above structure, one end is fixed to the free end of the horizontal stay 16 of the support stay main body 14, the other end is fixed to the vehicle body side, and the intermediate part is fixed to the vertical stay 15 via the fixing bracket 27.
Since the reinforcing stay 25 is fixed to the support stay 25, the rigidity of the support stay main body 14 can be increased compared to the conventional structure, and it is possible to increase the rigidity of the support stay main body 14 by increasing the strength of the support stay 14 due to wind pressure acting on the side mirror 13 while driving, transmission of vibrations from the vehicle body, etc. It is possible to prevent the entire support stay body 14 from vibrating. Therefore, it is possible to reliably prevent the mirror surface of the side mirror 13 from vibrating while driving and making it difficult to see the side mirror 13 as in the conventional case.
Safety can be increased. Furthermore, the structure can be simplified and the cost can be reduced compared to the case where the vertical stay 15 and the horizontal stay 16 of the support stay main body 14 are each reinforced by separate reinforcing stays.

It should be noted that this invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of this invention.

[Effect of idea]

According to this invention, a vertical stay is arranged on one side of the front windshield at the front of the vehicle body and has both upper and lower ends fixed to the vehicle body, and one end is fixed to the middle part of this vertical stay. The supporting stay body of the side mirror is formed by the sideways stay whose end extends toward the side of the vehicle body, and the side mirror is arranged substantially parallel to the sideways stay and connected laterally to the sideways stay via a connecting member. An overhang stay is provided that is slidably connected in a direction, and a side mirror is fixed to the tip of the overhang stay, one end of which is a free end of the horizontal stay, and the other end of which is fixed to the vehicle body side. Since a vibration-proof reinforcing stay whose intermediate part is fixed to the vertical stay is provided, the rigidity of the support stay body can be increased, and the vibration of the support stay body while driving is reduced, making it easy to see the side mirrors. In addition to being able to maintain the configuration, the configuration can be simplified.
