Description

The present invention relates to a stepladder for a back door of an automobile which is detachably attached to a back door of an automobile and can accommodate and load a stepladder.

One-box vehicles, which are often used as construction vehicles, are provided with a roof carrier for loading long objects such as stepladders.
The roof carrier includes a fixed roof carrier in which the cargo section is fixed and a movable roof carrier in which the cargo section is movable. When loading a stepladder or the like on a fixed roof carrier, the operator needs to lift the stepladder or the like and fix it on the roof. Therefore, a movable roof carrier is often used for the purpose of reducing the work. ..

As an example of this movable roof carrier, Japanese Patent Application Laid-Open No. 2002-36963 (hereinafter referred to as "Patent Document 1") has a loading platform frame that can be moved along a pair of left and right fixed rails, and is located in the middle near the center of the loading platform frame. The loading platform frame, which is pulled out until the pair of left and right rollers pivotally supported by the part is inscribed in the end stopper of the rail, is arranged outside the automobile so that the seesaw can be tilted with each roller as a fulcrum, and the loading platform frame is tilted downward toward the front. A roof rack equipped with a unidirectional elastic damper in the loading platform frame for alleviating the above is disclosed.

Further, the fourth stepladder for the back door of the automobile of the present invention is the first support column in which the base is attached to the back door of the automobile in parallel in the vertical direction in any one of the first to third aspects of the present invention. It is characterized by having a ladder-like shape composed of a second strut, a first strut, and a cross rail provided between the first strut and the second strut. With this configuration, a base with a simple structure and light weight can be realized.

Further, the fifth aspect of the present invention, the stepladder for the back door of the automobile, is characterized in that, in any one of the first to third aspects of the present invention, the base has a substantially rectangular plate-like shape. With this configuration, a base with a simple structure can be realized.

Further, the sixth aspect of the present invention, the stepladder for the back door of the automobile, is characterized in that, in any one of the first to fifth aspects of the present invention, the stepladder holder is a pair of left and right left-hanging pipes and right-hanging pipes. To do. With this configuration, it is possible to prevent the stepladder from falling off with a simple structure.

Further, in the seventh invention, the stepladder for the back door of the automobile of the present invention, in any one of the first to fifth aspects of the present invention, the stepladder holder is erected on the first flat plate and the tip of the first flat plate. It is characterized by being a second flat plate. With this configuration, it is possible to prevent the stepladder from falling off with a simple structure.

Further, the eighth stepladder for the back door of the automobile of the present invention is characterized in that, in any one of the first to seventh aspects of the present invention, a cushioning material is provided on the upper surface of the stepladder holder. The presence of the cushion material can reduce the vibration of the stepladder transmitted during transportation. Further, due to the presence of the cushion material, the stepladder hung on the stepladder holder is stable even if the distance between the stepladders and the stepladder holder is slightly different.

Since the stepladder for the back door of the automobile of the present invention is attached to the back door of the automobile, the stepladder can be easily loaded unlike the roof rack.
