Description

  The present invention relates to a vehicle including a load receiving table lifting device provided at a rear end of a loading platform, and in particular, the load receiving platform is lifted by moving a slider up and down through a wire by an expansion and contraction operation of an expansion cylinder disposed in a cross member. The present invention relates to a vehicle provided with a freely received cargo lift device.

  Conventionally, as a vehicle equipped with this kind of load receiving platform lifting device, a slider is inserted into a post erected on the left and right of the rear end of the vehicle loading platform, and the load receiving platform is supported by the slider. There is provided one in which a load receiving platform can be raised and lowered by raising and lowering a slider via a wire by an extension and contraction operation of an extension cylinder disposed in a cross member connected between the posts (for example, Patent Documents). 1).

  Specifically, as shown in FIG. 3, the load receiving platform lifting device includes a pair of left and right posts 2 erected at the rear end of the vehicle loading platform 1 and sub-posts 3 slidably inserted into the posts 2. And a tail gate 5 as a load receiving base supported rotatably by these left and right sliders 4, one end being fixed to the hydraulic cylinder 6 and the other end being fixed to each slider 4. The post 2, the sub-post 3, the slider 4, and the wire are provided symmetrically on both sides of the rear end of the loading platform 1.

  The slider 4 is lowered by feeding the wire from the hydraulic cylinder 6 side into the post 2 by the hydraulic cylinder 6, and the sub post 3 and the tail gate 5 are lowered at the same time. On the other hand, by pulling the wire toward the hydraulic cylinder 6 by the hydraulic cylinder 6, the tailgate 5 rises from the ground to the highest position where it is substantially the same as the floor surface of the loading platform 1 by the reverse operation.

  In this case, the hydraulic cylinder 6 is disposed in a cross member 7 provided at the rear end of the loading platform 1. The cross member 7 is configured such that the rear end portion of the loading platform 1 is cut by a length corresponding to the front-rear width, and disposed at the cut portion.

In order to conform to the legal regulations as a vehicle, a rod-like bumper 8 as shown in FIGS. 3 and 4 is separately provided between the lower ends of the post 2.
JP-A-8-230548

  However, the above-described conventional apparatus has a problem in that it takes a lot of time and burden to cut the rear end of the loading platform in order to dispose the cross member.

  Accordingly, the applicant pays attention to the position at which the cross member is disposed, and by placing the cross member at a predetermined position below the loading platform, the work load when the loading platform lifting device is attached to the loading platform of the vehicle is reduced. This cross member can also be used as a bumper.

In the vehicle provided with the load receiving platform lifting apparatus according to the first aspect of the present invention, the slider is inserted into the posts erected on the left and right sides of the rear end of the vehicle loading platform, and the load receiving platform is supported by the slider. In a vehicle provided with a load receiving table lifting device in which the load receiving table can be moved up and down by moving the slider up and down through a wire by an expansion and contraction operation of an expansion cylinder disposed in a cross member connected between the posts. The cross member is disposed at an appropriate height position that can be used as a rear bumper of the vehicle between the lower ends of the posts.

  According to the present invention, the loading platform lifting device can be easily attached to the rear end of the loading platform in a short time, the work load can be reduced, and the cross member can also be used as a rear bumper of the vehicle. The number of parts can be reduced and is very useful.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG.1 and FIG.2 has shown the vehicle provided with the cargo receiving stand raising / lowering apparatus of this invention. Note that the same members as those in the conventional load receiving table lifting apparatus described above are denoted by the same reference numerals and description thereof is omitted, and the lifting operation of the load receiving table is also the same, and thus description thereof is omitted.

  In the load receiving platform lifting apparatus, the cross member 7 is disposed between the lower end portions 2 a of the left and right posts 2. The cross member 7 is disposed so as to be disposed at an appropriate height position that complies with the laws and regulations and to ensure its strength so that it can be used as a rear bumper of the vehicle.

  The cross member 7 arranged in this way is provided with a telescopic cylinder (hydraulic cylinder) in the same manner as in the prior art, and the cross member 7 and the post 2 are connected to the telescopic cylinder and the slider 4. The wire is stretched as in the conventional case.

  By providing the cross member 7 in this way, when attaching the load receiving platform lifting device to the rear end of the loading platform 1, the left and right rear ends of the loading platform 1 need only be cut out by the amount of the left and right posts 2 disposed in a short time. This can be done easily and the work load can be reduced. In addition, since the cross member 7 can be used as a rear bumper of the vehicle, the number of parts can be reduced, which is very useful.

  Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

  For example, the present invention can also be applied to a load receiving table elevating device that does not have a sub-post and is provided with a slider that can be moved up and down directly in the post.

It is a rear view which shows the vehicle provided with the cargo receiving stand raising / lowering apparatus of this invention. It is a side view which similarly shows the vehicle provided with the load receiving table raising / lowering apparatus. It is a perspective view which shows the vehicle provided with the conventional cargo receiving stand raising / lowering apparatus. It is a rear view which similarly shows the vehicle provided with the conventional cargo receiving stand raising / lowering apparatus.

Claims (1)

Sliders are inserted into the posts that are erected on the left and right sides of the rear end of the loading platform of the vehicle, and the load receiving platform is supported by the sliders, and the expansion and contraction is disposed in the cross member that is connected between the posts. In a vehicle having a load receiving platform lifting device in which the load receiving platform can be moved up and down by moving the slider up and down through a wire by extending and contracting the cylinder, the cross member is used as a rear bumper of the vehicle between the lower ends of the posts. vehicle equipped with a receiving platform lifting device, characterized in that disposed in the proper vertical position as possible.
