Next, an embodiment of the present invention will be described. First, an outline of the vehicle carrier 1 will be described with reference to FIGS. 1 to 3. FIG. In the following description, the relationship between the front and back and the top and bottom is based on the front and back and the top and bottom of the vehicle transport vehicle 1 unless otherwise specified. That is, with respect to the front-rear direction, the driver's seat side of the vehicle transport vehicle 1 is the front side, and the opposite side is the rear side. Also, the width direction (left-right direction) of the vehicle hauler 1 will be described as the width direction. In addition, a case where the transported vehicle B is mounted on the carriage 13 so as to be aligned with the vehicle transporter 1 in the front-rear direction will be described as an example.

As shown in FIG. 2 or 3, the vehicle transport vehicle 1 includes a body frame 11, a tilt frame 12 that tilts with the rear facing downward with respect to the body frame 11, and the tilt frame 12. A carriage 13 that can slide in the front-rear direction is provided. A transported vehicle B (see FIG. 4) such as a passenger car can be mounted on the upper surface of the carriage 13 .

When the vehicle carriage 1 is traveling, the tilt frame 12 is in a horizontal position as shown in FIG. In this case, the foot board 14 is in a state of being erected so that the end portion thereof is positioned upward.

When the vehicle to be transported B is placed on and unloaded from the carriage 13, the carriage 13 is first moved rearward along the tilt frame 12 as shown in FIG. Next, the carriage 13 is landed on the ground surface G by increasing the tilt angle of the tilt frame 12 as shown in FIG. Then, by rotating the walking board 14 rearward about the axis on the base end side, the posture extended rearward as shown in FIG. 3 is assumed. In this posture, the foot board 14 is passed between the ground surface G and the carriage 3.

The footboards 14 are used to load and unload the vehicle B to be transported onto and off the carriage 13 . When the vehicle B to be transported is loaded onto the carrier 13, the vehicle B to be transported is made to travel forward from the ground surface G toward the carrier 13 via the walking board 14. - 特許庁On the other hand, when the transported vehicle B is unloaded from the carriage 13, the transported vehicle B is caused to travel backward from the carriage 13 toward the ground surface G via the step board 14. - 特許庁

In the vehicle carrier 1 configured as described above, the tire stopper device 2 of the present embodiment is installed on the carrier 13 . The tire stopper device 2 blocks the front wheels B1 of the vehicle B to be transported. The tire stopper device 2 has a tire stopper 21 and a boarding plate 22 .

The tire stopper 21 is attached to the carriage 13 . The tire stopper 21 of this embodiment is formed in the shape of a pipe with a hollow interior and a deformed rectangular cross-section, and is provided on the carriage 13 so that the longitudinal direction extends along the width direction of the vehicle carriage 1 ( See Figure 4). The tire stopper 21 is attached to the carriage 13 in front of the position of the front wheel B1 of the vehicle B to be transported. The tire stopper 21 mainly includes a base portion 211 , a carriage fixing portion 212 , a rear surface portion 213 , an engaging portion 214 , an insertion port 215 and a handle 216 . The tire stopper 21 of the present embodiment is formed by bending a steel plate and then welding it, but the material and assembly method are not particularly limited.

The base portion 211 is a portion that contacts the upper surface 131 of the carriage 13 and has a flat lower surface.

The carriage fixing portions 212 are provided, for example, one at each end in the longitudinal direction of the base portion 211, and are bar-shaped portions that extend obliquely downward from the rear portion of the base portion 211 and then bend and extend rearward. The carriage fixing portion 212 is inserted into a through hole 132 provided in the upper surface 131 of the carriage 13 (see FIG. 4). The shape of the carriage fixing portion 212 can be variously changed according to the shape of the structure for fixing the tire stopper 21 in the carriage 13 .

The rear surface portion 213 has an inclined surface with an upper portion positioned forward and a lower portion positioned rearward. The rear surface portion 213 of this embodiment is flat. However, it may be a curved surface that substantially matches the curvature of the tread surface of the front wheel B1, for example.

The engaging portion 214 is a protrusion projecting upward from the base portion 211 . The engaging portion 214 of the present embodiment is formed by bending upward the rear portion of the horizontally extending base portion 211 . The engaging portion 214 engages with the engaged portion 223 of the boarding plate 22, as shown in FIG.

The insertion port 215 is a through hole penetrating the lower portion of the rear surface portion 213 . The lower end of the insertion port 215 is aligned with the upper surface of the base portion 211 . A portion of the boarding plate 22 , specifically a front portion thereof as shown in FIG. Due to this insertion opening 215, even if part of the boarding plate 22 inserted into the tire stopper 21 is displaced upward, the boarding board 22 abuts the upper edge of the insertion opening 215, so that the deviation is further increased. should not. Therefore, it is possible to prevent a portion of the boarding plate 22 from being displaced in the vertical direction. Therefore, at the moment when the weight of the vehicle B to be transported concentrates on, for example, the rear portion of the boarding board 22 while the vehicle B is riding on the carriage 13, part of the boarding board 22 may be lifted. Fluttering can be suppressed.

Further, in this embodiment, the front end portion 225 of the boarding plate 22 is inserted so as to contact the inner surface (rear surface) of the front portion 216 of the tire stopper 21 . Therefore, it is possible to prevent the boarding plate 22 from being pushed forward by the front wheels B1 of the transported vehicle B running on it.

The handle 216 is positioned on the tire stopper 21 so as to extend diagonally forward at the center in the longitudinal direction. When attaching the tire stopper 21 to the carriage 13, the worker holds the handle 216 for work. In this embodiment, as shown in FIG. 6, the upper end of the handle 216 is positioned above the upper end of the rear surface portion 213 . However, it is not limited to this, and the position of the handle 216 can be set variously.

The boarding plate 22 is provided on the rear side of the tire stopper 21, as shown in FIG. The boarding plate 22 is a plate-like body that is rectangular in plan view. The width dimension of the boarding plate 22 is larger than the width dimension of the front wheel B1 of the vehicle B to be transported. The height of the rear portion 221 decreases toward the rear, and the upper surface of the rear portion 221 is sloped so that the vehicle to be transported B can ride on the boarding plate 22 smoothly. For this reason, the boarding plate 22 is substantially wedge-shaped. A plurality of non-slip grooves 222 for the front wheel B1 of the transported vehicle B are provided on the upper surface of the boarding plate 22 so as to extend in the longitudinal direction.

An engaged portion 223 is provided at the lower front portion of the boarding plate 22 . The engaged portion 223 is a rubber plate adhered to a concave portion 224 provided on the lower surface of the boarding plate 22 . As shown in FIG. 6 , the recess 224 has a rear recess 2241 located rearward and having a small depth, and a front recess 2242 located forward and having a greater depth than the rear recess 2241 . A rubber plate is adhered to the bottom surface of the front recess 2242 . Since the engaged portion 223 is made of an elastic rubber plate, the engaged portion 223 is deformed when the boarding plate 22 is attached to or detached from the tire stopper 21 . Therefore, it is easier to attach and detach the boarding plate 22 because it is less likely to get caught than when the engaged portion 223 is a rigid body.

By engaging the rear end portion 2231 of the rubber plate constituting the engaged portion 223 with the engaging portion 214 of the tire stopper 21 , the engaging portion 214 of the tire stopper 21 is engaged with the riding portion after engagement. Movement of the insert plate 22 in the front-rear direction (particularly rearward) is restrained. For this reason, particularly when the transported vehicle B is front-wheel drive, the driving front wheels B1 apply a rearward force to the boarding plate 22, but the engaging portion 214 and the engaged portion 223 are engaged. Therefore, it is possible to prevent the boarding plate 22 from being flipped backward, for example. Therefore, the riding board 22 is prevented from being separated from the tire stopper 21 by an external force (in this case, the driving force of the front wheel B1), and the transported vehicle B can be stably run on the boarding board 22. - 特許庁

A boarding board 22 is placed on the upper surface 131 of the carriage 13 , and the transported vehicle B is mounted on the boarding board 22 . Therefore, the portion of the transported vehicle B around the front wheel B1 can be arranged at a higher position by the thickness of the boarding plate 22 . Therefore, even if the transported vehicle B has a low ground clearance, the possibility of the transported vehicle B interfering with the onboard equipment such as the tire stopper 21 and the winch 15 provided on the transporting platform 13 is prevented from occurring on the transporting platform 13. can be reduced as much as the height of

The boarding plate 22 is detachable from the tire stopper 21, as shown in FIGS. 5(a) and 5(b). The boarding board 22 is placed on the carriage 13, and the front wheels B1 of the transported vehicle B run on it. Here, the foot board 14 of the vehicle transport vehicle 1 is passed between the ground surface G and the transport platform 13 when the transported vehicle B is loaded onto and unloaded from the transport platform 13, as shown in FIG. As shown in FIG. 5( a ), the boarding board 22 is separated from the tire stopper 21 , and then is positioned behind the walking board 14 (position P22 shown in FIG. 3 ) from the ground surface G. The transported vehicle B moving to 14 is arranged to pass while riding on it. With this configuration, the boarding plate 22 can be used together with the tire stopper 21 as described above, and further, when the vehicle B to be transported is moved to the carriage 13, the difference in level between the ground surface G and the footboards 14 can be reduced. Also, by reducing the angle difference between the ground surface G and the footboard 14, the transported vehicle B can be smoothly moved from the ground surface G to the carriage 13.例文帳に追加As described above, the tire stopper device 2 of the present embodiment is useful because it can be applied to the transported vehicle B having a low ground clearance and is excellent in versatility.

As mentioned above, although one embodiment was taken up and described about this invention, this invention is not limited to the said embodiment. For example, as shown in FIG. 7, the tire stopper 21 does not have the insertion opening 215 as in the above embodiment, and the base portion 211 is extended more rearward than in the above embodiment. can also be configured to be attached to the rear of the rear surface portion 213 . Further, in the above-described embodiment, an example of application to a vehicle carrier carrying one vehicle was given, but the present invention may be applied to a vehicle carrier carrying two or more vehicles.
