JP 2002-59050 A

  By the way, the speed sprayer sprays the chemical solution while running between a large number of fruit trees in an orchard or the like, so that it is easy to hit the branches and fruits of the fruit tree hanging down. Particularly, since the rearview mirror is provided in such a manner that it partially protrudes laterally from the vehicle body, when the rearview mirror hits a branch or a leaf, the fruit may be peeled off or the branch or leaf may be damaged. Therefore, if the rearview mirror can be folded to a storage position that does not protrude from the cabin as required, it is possible to protect the branches and leaves of the fruit tree and from the standpoint of garage entry.

  In this case, the cabin type speed sprayer as described in the above publication has a cabin similar to that of a general automobile, and the rearview mirror can be attached to the front portion of the side door as in the case of a general automobile. . In other words, since the rear mirror can be pivotally attached to the front part of the side door via the vertical axis, if the rearview mirror is pivotally displaced at a right angle from the use position, the side door window Can be folded to a storage position that is substantially parallel to the object, and the object can be easily achieved.

  However, in the case of a speed sprayer without a cabin where the driver's seat is open and provided with a bonnet having a curved inclined surface portion immediately in front of the driver's seat, it is necessary to attach a rearview mirror to the hood and Since the mirror is composed of a mirror main body and an L-shaped mirror arm that supports the mirror main body, the rearview mirror cannot be easily stored and a desirable storage mode cannot be easily obtained. There was a problem to be solved.

  An object of the present invention is to provide a rearview mirror device for a speed sprayer that solves such problems in the background art.

  In order to solve the above-described problems, the present invention provides a rear surface mirror 2 having a mirror body 2m and a mirror arm 2a bent in an L shape that supports the mirror body 2m. When configuring the rearview mirror device 1 of the speed sprayer M attached to 4s, the mirror arm 2a can be rotated with respect to the mounting seat surface 5 of the bonnet 4, and at least the use position Xu at which the rearview mirror 2 can be used. The rearview mirror 2 is attached to the attachment seat surface 5 by a bolt portion 11 provided on the mirror arm 2a and a nut portion 13 via a spring washer 12 so that the rearview mirror 2 can be stopped at the retracted position Xh in contact with or close to the bonnet 4. At the same time, the rearview mirror 2 at the retracted position Xh is substantially parallel to the outer surface of the bonnet 4 on the mounting seat surface 5. To, and characterized by being set to a predetermined angle Rs with respect to the horizontal plane H.

  In this case, according to a preferred aspect of the invention, the mirror arm 2a can be provided with a position restricting portion 14 that stops the rearview mirror 2 at least at the use position Xu. Further, the outer surface 4f of the bonnet 4 where the rearview mirror 2 stopped at the storage position Xh can be formed lower than the other outer surface 4fe of the bonnet 4 via the step portion 4b.

  According to the rearview mirror device 1 of the speed sprayer according to the present invention having such a configuration, the following remarkable effects can be obtained.

  (1) Even in the case of the speed sprayer M without an open cabin in the driver's seat 3, the rearview mirror 2 can be easily stored in the storage position Xh that does not protrude from the outer surface 4f of the bonnet 4, and a desirable storage mode is easily obtained. be able to.

  (2) The mirror arm 2a is an existing rearview mirror 2 that is fixedly mounted because the mirror arm 2a is mounted on the mounting seat surface 5 by the bolt portion 11 provided on the mirror arm 2a and the nut portion 13 via the spring washer 12. However, the storage type can be easily changed without incurring a cost increase.

  (3) According to a preferred embodiment, if the mirror arm 2a is provided with the position restricting portion 14 for stopping the rearview mirror 2 at least at the use position Xu, the rearview mirror 2 is displaced from the storage position Xh to the use position Xu. Therefore, it is possible to always stop at the constant use position Xu, and it is possible to further improve handling and convenience.

  (4) If the outer surface 4f of the bonnet 4 where the rearview mirror 2 stopped at the storage position Xh is positioned lower than the other outer surface 4fe of the bonnet 4 via the stepped portion 4b according to a preferred embodiment, the bonnet 4 The degree of protrusion of the rearview mirror 2 from the outer surface 4f of the hood 4 can be further reduced, and the bonnet 4 itself can be increased in strength.

  Next, the best embodiment according to the present invention will be given and described in detail with reference to the drawings.

  First, a schematic configuration of the speed sprayer M including the rearview mirror device 1 according to the present embodiment will be described with reference to FIGS. 1 and 2.

  In the speed sprayer M, 51 is a chassis, which has front wheels 52 on the front side of the chassis 51 and left and right rear wheels 53 on the rear side. As a result, the speed sprayer M is self-propelled by the mounted engine. On the other hand, the body 54 on the chassis 51 includes the driver's seat 3 at the front. Further, the hood 4 in front of the driver's seat 3 is provided with necessary vehicle equipment such as headlights 55 and the like, and the rearview mirror device 1 according to the present embodiment is attached. On the other hand, a chemical tank and a chemical spray mechanism that do not appear in the figure are mounted behind the driver's seat 3, and this chemical spray mechanism includes a blower and a number of injection nozzles.

  Next, the configuration and function of the rearview mirror device 1 according to the present embodiment (first embodiment) will be specifically described with reference to FIGS.

  The rearview mirror device 1 is attached to the inclined surface portion 4s of the bonnet 4 having a curved surface in front of the driver seat 3 of the speed sprayer M. In this case, the rearview mirror devices 1 are attached to the left and right sides of the bonnet 4, respectively. As shown in FIG. 4, the rear-view mirror device 1 on the left side (right side in FIG. 1) includes a rear-view mirror 2 having a mirror body 2m and a mirror arm 2a that supports the mirror body 2m. The mirror arm 2a is formed of a single round bar bent into an L shape, and includes a relatively short standing portion 2as and an extending portion 2aw extending laterally from the upper end of the standing portion 2as. And while supporting the back surface of the mirror main body 2m via the universal joint part 21 etc. which can set an angle arbitrarily by the front-end | tip of the extension part 2aw, the volt | bolt part 22 attached to the bonnet 4 side is provided in the lower end part of the standing part 2as. Provide one. The bolt portion 22 includes a flange portion (head) 22h and a screw portion 22n.

  On the other hand, a mounting seat surface 5 for attaching the rearview mirror 2 is provided on the inclined surface portion 4 s of the bonnet 4. In this case, the concave portion 24 is formed in a predetermined portion of the inclined surface portion 4s, and the mounting seat surface 5 inclined by the predetermined angle Rs with respect to the horizontal plane H is provided as shown in FIG. In the case of the mounting seat surface 5 formed on the left side of the bonnet 4, the predetermined angle Rs is set to an angle that rises to the left. The size of the predetermined angle Rs is set such that the rearview mirror 2 at the storage position Xh is substantially parallel to the outer surface 4f of the bonnet 4 as will be described later. In the example, the predetermined angle Rs is preferably 10 to 20 [°].

  Furthermore, a part of the outer surface 4f of the bonnet 4 is formed lower than the other outer surface 4fe of the bonnet 4 via the step portion 4b. Specifically, as shown in FIG. 2, by forming a stepped portion 4b along the front-rear direction, a part of the outer surface 4f of the bonnet 4 is Ls more than the other outer surface 4fe as shown in FIG. The rear-view mirror 2 stopped at a storage position Xh, which will be described later, is formed on a part of the outer surface 4f. If the outer surfaces 4f and 4fe of the bonnet 4 are formed in this way, there is an advantage that the degree of protrusion of the rearview mirror 2 from the outer surface 4f of the bonnet 4 can be reduced and the strength of the bonnet 4 itself can be increased.

  As shown in FIG. 4, a mounting hole 25 is formed in the mounting seat surface 5, and the screw portion 22 n of the rearview mirror 2 is inserted into the mounting hole 25 from above, and the screw portion from below the mounting hole 25. A double nut 27 is screwed onto 22n through a washer 26. Thereby, the rearview mirror 2 is attached to the attachment hole 25 so as to be rotatable. Further, the mirror arm 2a is provided with a buckling mechanism portion 15 and a position restricting portion 16 for stopping the rearview mirror 2 at the use position Xu. That is, as shown in FIGS. 4 and 5, a lever portion 28 protruding in a right angle direction is fixed to the lower end of the screw portion 22n, and provided at a predetermined position on the tip side of the lever portion 28 and the back surface (inner surface) of the bonnet 4. A spring 30 is installed between the hook portions 29 to form the buckling mechanism portion 15, and the back surface (inner surface) of the bonnet 4 is locked to the lever portion 28 at a predetermined position so that the rotation range of the lever portion 28 is set. A restricting stopper 31 is provided. At this time, the buckling mechanism unit 15 is set so that a buckling point is generated between the use position Xu and the storage position Xh.

  As a result, when the rearview mirror 2 is pivotally displaced by hand, the use position Xu indicated by the phantom line in FIGS. 1 and 2 and indicated by the solid line in FIG. 3 and the storage position Xh indicated by the solid line in FIGS. The rearview mirror 2 can be used at the use position Xu, and the rearview mirror 2 can be brought into contact with the hood 4 at the storage position Xh. In this case, since the buckling mechanism portion 15 and the position restricting portion 16 are provided, the lever portion 28 is urged clockwise by the spring 30 and engaged with the stopper 31 at the use position Xu as shown by the solid line in FIG. At the retracted position Xh, the lever portion 28 is urged counterclockwise by the spring 30 as shown by the phantom line in FIG. Comes into contact with the outer surface 4f of the bonnet 4 and is fixed (stopped) at the storage position Xh. In order to prevent the bonnet 4 from being damaged even if the mirror main body 2m contacts the bonnet 4, it is desirable to provide a cushioning material such as rubber on the surface of the mirror main body 2m facing the bonnet 4.

  By the way, the predetermined angle Rs of the mounting seat surface 5 described above is set so that the rearview mirror 2 at the storage position Xh is substantially parallel to the outer surface 4 f of the bonnet 4. That is, by changing the predetermined angle Rs of the mounting seat surface 5, the angle of the rearview mirror 2 at the storage position Xh with respect to the outer surface 4f of the bonnet 4 can be changed, so that the rear surface mirror 2 and the outer surface 4f of the bonnet 4 at the storage position Xh Set to be approximately parallel. The fact that the rearview mirror 2 in the present invention is substantially parallel to the outer surface of the bonnet 4 means that the projection width of the rearview mirror 2 from the outer surface of the bonnet 4 is the smallest at the storage position Xh. Therefore, it is not always necessary to be physically parallel.

  Further, as shown in FIG. 6, the vicinity of the tip of the extended portion 2aw of the mirror arm 2a can be divided and connected with an elastic material such as a spring coil 33 interposed therebetween. In this case, the spring coil 33 is a spring coil that maintains a straight line in a natural state and is allowed to bend by an external force. Thereby, even if the mirror body 2m is set at the angle by the universal joint portion 21, it can escape when the mirror body 2m comes into contact with the outer surface 4f of the bonnet 4, and the angle setting of the mirror body 2m is shifted. In addition to avoiding defects, it is possible to secure more desirable parallelism due to surface contact.

  Therefore, according to such a rearview mirror device 1, the rearview mirror 2 can be easily stored in the storage position Xh that does not protrude from the outer surface 4f of the bonnet 4 even in the case of the speed sprayer M with the cabin 3 opened and without the cabin. In addition, a desirable storage mode can be easily obtained. In addition, when the rearview mirror 2 is displaced from the storage position Xh to the use position Xu, it can always be stopped at the constant use position Xu, so that handling and convenience can be further improved.

  The left-side rearview mirror device 1 has been described above. However, the right-side rearview mirror device 1 is also symmetric with respect to the left-side rearview mirror device 1 in terms of form and movement. It can be configured in the same manner. In the right rearview mirror device 1, the outer surface of the bonnet 4 where the rearview mirror 2 stopped at the storage position Xh is the other outer surface 4fe described above, and such an embodiment is also included in the present invention. The illustrated embodiment is an example in which the type in which the rearview mirror 2 is fixed to the bonnet 4 is improved as it is, but the right rearview mirror device 1 and the left rearview mirror device 1 are also different. Similarly, if the outer surface 4f of the bonnet 4 where the rearview mirror 2 stopped at the storage position Xh is located is formed lower than the other outer surface 4fe of the bonnet 4 via a step portion, a more desirable form is obtained.

  Next, the configuration and function of the rearview mirror device 1 according to the second embodiment of the present invention will be specifically described with reference to FIG.

The screw portion 35n is inserted into the mounting hole 25 formed in the seat surface 5 from above, and the washer 26 and the spring washer 12 stacked on the washer 26 are attached to the screw portion 35n from below the mounting hole 25, and Then, the nut portion 13 using the double nut 36 is screwed.

  As a result, the rearview mirror 2 is rotatably attached to the attachment hole 25 with a certain amount of friction. Therefore, if the rearview mirror 2 is rotationally displaced by hand, it is positioned at the use position Xu or the storage position Xh. The rearview mirror 2 can be stopped by friction by the spring washer 12 at the use position Xu and the storage position Xh. According to such a second embodiment, there is an advantage that even the existing rearview mirror 2 fixedly attached can be easily changed to the storage type without causing an increase in cost.

  On the other hand, the mirror arm 2a may be provided with a position restricting portion 14 for stopping the rearview mirror 2 at the use position Xu as indicated by a virtual line in FIG. In this case, a lever portion 37 protruding in a right angle direction is fixed to the lower end of the screw portion 35n, and a stopper portion 38 that is locked to the lever portion 37 at the use position Xu is fixed to the bonnet 4 side. Good. By providing such a position restricting portion 14, when the rearview mirror 2 is displaced from the storage position Xh to the use position Xu, it can always be stopped at the constant use position Xu, thereby improving handling and convenience.
