DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling compact vehicle provided with an illuminating device for illuminating a compacting wheel at the time of compacting work at night or the like.

[0002]

2. Description of the Related Art When rolling is performed at the very edge of a structure such as a curb or a wall, a driver of a rolling vehicle needs to be careful that the outer surface of the rolling wheel does not come into contact with the structure. However, at night, the part of the rolling wheel becomes dark and visibility becomes poor, so in general, during nighttime rolling work, the lighting device mounted on the vehicle is turned on to illuminate the rolling wheel and good I try to secure the view. FIG. 8A is a plan view of a conventional compacted vehicle (rear wheel drive type tire roller R) that is about to enter the compaction road surface S, and is normally driven when entering the compaction road surface. Since the vehicle enters from the wheel side, in this case, a state of approaching in reverse is shown. At night, the lighting device 92 attached to the frame 91 of the tire roller R is turned on to illuminate the tire 93 serving as the outermost driving wheel, and the driver sitting in the driver's seat 94 looks directly back while looking back. Alternatively, while confirming the position of the tire 93 with the rearview mirror 95, the vehicle accurately enters the rolling contact road surface S, and repeats forward and backward.

[0003]

However, in a conventional compacted vehicle, as shown in FIG. 8B, an illuminating device 92 is mounted near the front end of a frame 91, and an illuminated surface 92a is provided. Since the driver is set sideways toward the driver's seat 94 located at the rear, the irradiation light directly enters the driver's eyes, making the driver dazzling and difficult to see in front. People complain of eye fatigue. In addition, since the distance between the lighting device 92 and the tire 93 is large, the lighting device 92 needs to have a sufficient amount of light at the portion of the tire 93.
However, there is a problem that the battery capacity becomes insufficient when other electric components are optionally attached to the tire roller R.

A lighting device 92 is mounted on a bracket 96 which is bolted to the upper surface of a frame 91, and a tire 93 in the width direction of the tire roller R.
Because it is installed to protrude outward than
As shown in FIG. 8C, when rolling the structure K having a height higher than that of the frame 91, the bolt is loosened to prevent the collision with the structure K so that the bracket 96 may be loosened.
At the same time, the lighting device 92 must be removed, and the work of removing or re-attaching the lighting device 92 has been a very laborious operation. Of course, in the case where the lighting device 92 is detached and the rolling operation is performed, the driver continues the rolling operation at the structure K in a dark field of view, and the tire 93 collides with the structure K by mistake. There was also a fear.

The present invention has been made in order to solve such problems, and can reduce the driver's eye fatigue of a compacted vehicle, thereby ensuring the safety of compaction work. An object of the present invention is to provide a compacted vehicle that can improve the compacting work efficiency at night without having to remove the lighting device even when compacting a tall structure.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a lighting device having a lighting device projecting from the side of a frame in the width direction of a compacted vehicle to illuminate the compacted wheel at night or the like. A pressurized vehicle, wherein the lighting device is mounted on an upper portion of a frame so that an irradiation surface thereof faces downward, and the lighting device is made to be able to be tilted in the front-rear direction of the compacted vehicle, so that the lighting device A compacted vehicle that can be stored inside.

[0007] Next, there is provided a rolling compact vehicle having a compaction wheel whose overall width is larger than the width dimension of the frame, and the frame of the compacting wheel does not protrude beyond the outer surface of the compacting wheel in the width direction of the compaction vehicle. A rolling compact vehicle having an illuminating device provided on a side portion for illuminating the compacting wheel at night or the like. Further, the lighting device is provided so as not to protrude from the outer portion of the frame in the width direction of the compacted vehicle. Further, the lighting device is configured to be provided in a step portion formed such that a lower width dimension is smaller than an upper width dimension on a side portion of the frame. In addition, the lighting device is configured to be provided at a position that does not overlap with the rolling wheel in plan view.

A type with a built-in ball is used. As shown in FIG. 2 (c), the lighting device 3 is configured such that a plurality of base plates 7 which can be tilted (rotated) in the front-rear direction of the tire roller R and to which a support shaft 6 having a step is fixed vertically are provided. Is fastened and fixed to the upper surface of the frame 1 with the bolts 13 of
A cylindrical member 9 to which the lighting device 3 is attached is externally rotatably fitted to a small diameter portion 6 a of the support shaft 6 via an arm 8. The irradiation surface 5a is set to face downward,
As shown in FIGS. 1 and 2 (a), when the frame 1 protrudes from the side 1a, the outer surface of the tire T is illuminated. In the present example, the illumination device 3 is attached so that the irradiation surface 5a irradiates parallel to the road surface, that is, directly downward. The downward angle of the irradiation surface 5a is
It can be appropriately selected in consideration of the mounting position of the lighting device 3 in the front-rear direction of the tire roller R (in this example, between the driver's seat 2 and the tire T), the irradiation angle θ of the lighting device 3, and the like. More preferably, the angle is set within a range of ± 30 ° in the front-rear direction.

Further, in the present embodiment, the lighting device 3 is securely positioned at a certain position protruding from the side portion 1a of the frame 1 and at a certain position when stored inside the side portion 1a of the frame 1. And a positioning means for positioning the motor. In this embodiment, a plurality of recesses 1 are formed in the small-diameter portion 6a of the support shaft 6 at a constant interval (90 ° interval in this embodiment) along the circumferential direction.

As described above, if the illuminating device 3 is mounted on the frame 1 so that the irradiation surface 5a faces downward, light does not directly enter the eyes of the driver, and eyestrain is reduced. As a result, the driver can safely continue the compaction work. In addition, the lighting device 3 is configured to be capable of being retracted in the front-rear direction of the compacted vehicle so as to be retractable inside the side portion 1a of the frame 1 so that the lighting device 3 can be stored.
This makes it extremely easy to set up the work during rolling work and to store the work during non-working, and to improve the efficiency of the work during nighttime. Furthermore, during the rolling work, even if the lighting device 3 unexpectedly collides with a partially protruding structure or a tree, the lighting device 3 automatically falls forward or backward and is stored inside the frame 1. , Without excessive force
The damage to the lighting device 3 can be prevented. In addition, since the mounting portion of the lighting device 3 is located above the tire T, a sufficient light amount can be secured by a light source having a small power capacity, and other electric components can be mounted on the tire roller R without increasing the battery capacity. Can be mounted.

Next, a description will be given of means for turning on and off the lighting device 3. Generally, a compacted vehicle is equipped with a night work light 16 illuminating the rear of the vehicle for the purpose of calling attention to a worker behind the vehicle during night work and obtaining the driver's rear view. (Headlights illuminate the front of the vehicle). This is to turn on and off when the driver of the compaction vehicle turns on and off a dedicated night work light switch provided in the driver's seat or the like during nighttime construction.
In the present embodiment, as lighting / extinguishing means of the lighting device 3,
Using the electric signal for the night work light 16, the lighting device 3
Is connected in parallel with the switch circuit of the night work light 16 so as to interlock with turning on and off the night work light 16. Therefore, the existing electric circuit can be used as it is, and there is no need to newly provide switches dedicated to the lighting device 3 around the driver's seat. it can. It is possible to connect the switch circuit of the lighting device 3 in parallel with the switch circuit of the headlight. However, in this case, the lighting device 3 is turned on even when the vehicle is transported at night, which is not a good idea. .

Next, a second embodiment will be described with reference to FIG. FIG. 3A is a side view of the tire roller, and FIG.
FIG. 3 (b) is a view taken in the direction of the arrow C in FIG. 3 (a), and FIG.
FIG. 3 is a view as seen from the arrow D in FIG. Also in the tire roller R in the present embodiment, the overall width L2 of the rear wheel composed of the plurality of tires T is larger than the width L3 of the frame 1 and the tire T is located outside the side portion 1a of the frame 1 in the width direction. The lighting device 21
As shown in FIG. 3B, in the width direction of the tire roller R, the irradiation surface 21a faces the tire T so as not to protrude beyond the outer surface Ts of the tire T.
Is provided on the side portion 1a. As the light source, an incandescent bulb or the like is used as in the above embodiment. Accordingly, even when the rolling work is performed with the tire T positioned at the very edge of the structure, the lighting device 21 does not come into contact with the structure, thereby preventing the lighting device 21 from being damaged. it can. Further, the driver of the compacted vehicle is freed from the trouble of setting or storing the lighting device 21 every time the compacting work is performed at night. The lighting and extinguishing of the illumination device 21 are linked to the lighting and extinguishing of the night work lamp 16 by the same configuration as in the first embodiment.

Here, when the rolling compaction work is performed just before the structure, the places that the driver must pay close attention to are:
Although the outer surface Ts of the tire T is the edge of the outer surface Ts before and after the ground portion of the outer surface Ts, the lighting device 21 has the outer surface Ts.
If the lighting device 21
Is positioned directly above the tire T, the irradiation light can directly illuminate only the upper surface of the tire T. Of course, even in the case where direct irradiation is not performed, indirect light reflected from the road surface makes it possible to visually check the vicinity of the ground portion on the outer surface Ts. However, in the present embodiment, in order to improve visibility, FIG. 3
As shown in FIG. 3 (c), the illumination device 21 is positioned so as not to overlap with the tire T in a plan view, thereby enabling irradiation from an obliquely upper side. Is directly illuminated at the edge (indicated by reference numeral 22) of the outer surface Ts below the center. Accordingly, the driver can accurately grasp the position of the tire T, and can perform an accurate rolling work without causing the tire T to collide with the structure.

The lighting device 31 is attached to the frame 1 so as not to protrude beyond the side portion 1a of the frame 1 in the width direction of the tire roller R, as shown in FIG.

In general, a compacted vehicle travels with compaction while spraying water for the purpose of cooling the compacted road surface and preventing asphalt mixture from adhering to the compacted wheels.
The frame has a structure also serving as a tank for storing the water for sprinkling. Therefore, in order to secure this water storage amount, the frame must be enlarged, and FIG. As shown in the figure, the distance L1 between the side portion 1a of the frame 1 and the outer surface Ts of the tire T in the width direction of the compacted vehicle is usually very small, about several tens mm in many cases. Here, in the case where the rolling work is performed at the very edge of a structure having a height as large as a tire diameter by using this rolling vehicle, if the structure K is curved as shown in FIG. Then, the side portion 1a comes into contact with the structure K, and both the frame 1 and the structure K are damaged.

As shown in FIG. 4 (c), the tire roller R in the present embodiment is provided with a side portion 1a of the frame 1 for the purpose of both preventing the contact with the curved structure and securing the water storage amount. In a position slightly above the top of the tire T, a step portion 32 is formed as a so-called curve clearance so that the lower width dimension is smaller than the upper width dimension. Due to the mode of attachment to the portion 32, the layout does not protrude from the side portion 1a of the frame 1. The illuminating device 31 of the present example is provided with a 20-watt incandescent bulb as a light source, a rectangular parallelepiped cover 33 made of a transparent resin material as a housing, and having one surface facing the tire T as an irradiation surface 31a. And the step portion 3 via the vibration isolating rubber 35
2 is fixed.

As described above, the illuminating device 31 is attached to the outer portion (side portion 1) of the frame 1 in the width direction of the tire roller R.
If the structure is provided so as not to protrude beyond a), when the rolling work is performed with the tire T positioned at the very edge of the structure, even if there are some protrusions on the surface of this structure, Since the frequency with which the lighting device 31 contacts the projection is extremely small, it is possible to prevent the lighting device 31 from being damaged. Also, a step portion 32 which is a curve clearance.
By mounting the lighting device 31 on the frame 1, there is no need to newly process the mounting portion of the lighting device 31 on the frame 1, and it is possible to use a tire roller that is not equipped with a lighting device in common. In the present embodiment as well, for the purpose of improving the visibility of the tire T, the illumination device 31 is positioned so as not to overlap the tire T in a plan view so that irradiation from an obliquely upper position is possible. As shown in (b), the edge (indicated by reference numeral 36) of the outer surface Ts below the center of the tire T is directly illuminated. In addition, turning on and off of the lighting device 31
With the same configuration as the first embodiment, the night work light 16
It is linked with turning on and off.

Next, a fourth embodiment will be described with reference to FIG. FIG. 5A is a partial side view of the tire roller, and FIG. 5B is a view as viewed from an arrow F in FIG. 5A. Also in the tire roller R in the present embodiment, similarly to the third embodiment, the tire T projects outside the side portion 1a of the frame 1 in the width direction, and the lighting device 41 is arranged as shown in FIG. As shown, in the width direction of the tire roller R, it is the same that it is attached to the frame 1 so as not to protrude beyond the side 1a of the frame 1, but the side of the frame 1 is used as the aforementioned curve clearance. 1
a presents an inclined surface 1b in a lower portion, and is different in that a lighting device 41 is provided in a concave portion 42 formed in the inclined surface 1b. The recess 42 is provided in the lighting device 41.
In order to irradiate the tire T with the irradiation light from the tire T, the notch is formed so as to face the tire storage portion 43 that stores the tire T.

As described above, the concave portion 42 is formed on the side surface of the frame 1.
Is formed, and the lighting device 41 is provided so as not to protrude from the outer portion (side portion 1a) of the frame 1 in the width direction of the tire roller R even in a mode in which the lighting device 41 is attached to the concave portion 42. And it is possible to
When the rolling work is performed with the tire T positioned very close to a structure such as a wall, even if there are some protrusions on the surface of this structure, the frequency at which the lighting device 41 contacts the protrusions Is extremely small, so that the lighting device 41 can be prevented from being damaged.

FIG. 6 shows a modification of the fourth embodiment. As a curve clearance of the tire roller R, the side of the frame 1 has an inclined surface 1c from the upper end to the lower end. In this embodiment, a concave portion 52 is formed, and the lighting device 51 is attached to the concave portion 52.

The preferred embodiment of the rolling vehicle according to the present invention has been described above. In the above-described embodiment, the case where the roller is a tire roller has been described. However, the present invention is also applicable to an iron wheel type roller-mounted vehicle. If the front wheel is of a type protruding from the frame, it goes without saying that the lighting device is mounted to illuminate the front wheel. The lighting device may use a fluorescent lamp or the like, and the constituent means of the present invention are not limited to the contents described in the drawings, and the design can be appropriately changed without departing from the spirit of the present invention.
