Description

Rear carrier

The present invention relates to a rear carrier that supports luggage attached to the main surface (rear surface of the vehicle) of the back door (also referred to as a rear door) of a one-box car.

Conventionally, a roof carrier is often used when attaching luggage to the outside of a vehicle. If the vehicle is a one-box car, the height of the vehicle may be too high to reach from the ground when trying to attach luggage to the roof, so steps, stepladders, etc. must be used. If the luggage is attached using a stepladder, the stepladder cannot be attached to the roof.
Therefore, in addition to the roof carrier, the one-box car uses a rear carrier that can attach luggage to the back door.
The carrier disclosed in Patent Document 1 mounts an article storage box by hooking a vehicle fixture in the vertical direction of the back door.
The carrier disclosed in Patent Document 2 includes a housing body that receives and holds an article from above, a hanging member that supports the storage body in a suspended state on a back door, and a housing body that is detachably fixed to the outside of the back door. It consists of a fixing member, and the housing body is attached to the outside of the back door.

However, since the carriers disclosed in

Patent Documents

1 and 2 all use a mounting tool or a hooking member that hooks in the vertical direction of the back door, the mounting tool or the hooking member is once mounted at a predetermined position on the back door. If the article storage box or the storage body is attached after that, the license plate and tail lamp may be hidden. In this case, the mounting position of the mounting tool or the hooking member had to be shifted so that the license plate or the like could be seen, which made the re-mounting work complicated.
Further, the carrier disclosed in

Patent Documents

1 and 2 is box-shaped, may obstruct the rear view, and may not be able to accommodate a long object such as a stepladder or ski.
