[Prior art]

 Most conventional portable trunk carriers are foldable or have a telescopic grip bar to reduce the volume when stored and make it easier to carry. In addition, in order to obtain the overall strength required for use and a height convenient for use, a trunk propulsion grip bar and a grip bar used for expansion and contraction control are provided, and further three-tiered tubular body is locked or engaged in the tube. In some cases, a structure for releasing the stop is provided to connect and fix the pipes.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional technique has a drawback that the structure is complicated and therefore the manufacturing cost is high. Therefore, in the present invention, by incorporating a unique mechanism in each tubular member that is a constituent element, locking of the tubular member during stretching and unlocking during storage can be reliably performed with a simpler operation. An object is to provide a trunk carrier.

[0004]

 The portable trunk carrier of the present invention is provided with a first tubular member, two sets of the second tubular member in the first tubular member and two sets of the third tubular member in the second tubular member, respectively. These are isolated and held in parallel so that they can be freely extended and contracted. The lower end of the first tubular member is inserted into a tubular portion formed integrally with a lower support member having a mounting base, and a roller is provided outside the tubular portion. Further, the upper end of the third tubular member is inserted into and fixed to a tubular portion formed integrally with the holding bar, and the above is the basic structure.

In the above basic structure, a hollow portion is provided in the center of the grip bar in advance, and a push plate having a cross bar and movable up and down is provided in the hollow portion.

Further, shaft sleeves made of a plastic material are attached inside the upper ends of the first tubular member and the second tubular member, respectively.

A fixing seat is provided at an upper end of the first tubular member, and compression coil springs are horizontally provided at both ends of the fixing seat, and a mooring pin is fixed to one end of the compression coil spring. The tubular members are inserted into holes provided at the upper end of the member and the lower end of the second tubular member, respectively, and both tubular members are locked and fixed.

A compression coil spring is provided in the vertical direction at both ends of a push plate provided in the grip bar.

A hook bar extending downward is provided inside the second tubular member, and an upper end of the hook bar engages with both ends of the cross bar with a screw, and a lower end freely moves in the third tubular member. Stick to a guide block that can be moved to.

Further, a guide bar integrally formed with a circular head is provided at the lower end of the guide block, and a semi-slope is formed immediately below the guide block, that is, in the middle of the guide bar. Clip-shaped compression springs are attached to the hollow portion of the third tubular member facing the semi-oblique body by compressing them in opposite directions in the two sets of tubular members. A mooring pin is connected and fixed to one end of the clip-shaped compression spring. The other end is fixed to the wall of the third tubular member by soldering.

Further, the mooring pin connected to the clip-shaped compression spring and the mooring pin connected to the compression coil spring of the fixed seat are formed in a bolt shape, the head at one end is formed in a round shape, and the rod at the other end is smooth. To form.

[0012]

When the present invention is extended from the stored state, the grasping bar is grasped and the pushing plate is pushed and pulled up to fully extend the second tubular member and the third tubular member. When the push plate is released, the third tubular member and the second tubular member are locked by the mooring pin of the clip-shaped compression spring provided in the third tubular member. Further, the second tubular member and the first tubular member are locked by the mooring pin provided on the compression coil spring of the fixed seat.

When the present invention is stored, the user first holds the grip bar and pushes the push plate. Then, the guide bar is pulled up through the hook. Along with that, it passes through the mooring pin of the clip-shaped compression spring along the narrow part and the wide part of the semi- slanted body of the guide bar, and is pulled out from the holes of the second and third tubular members toward the hollow direction. Is unlocked.

When the user further pushes the grip bar downward, the unlocked third tubular member is housed in the second tubular member. At the same time, with the pressing of the gripping bar, the guide bar descends and its rounded end passes through the head of the mooring pin of the fixed seat, so that the mooring pin is pushed into the fixed seat. That is, the locking between the second and first tubular members is released. When the user pushes the grip bar down as much as possible, the second tubular member is completely contained within the first tubular member.

Upon completion of storage, each tubular member is firmly locked so as to be compressed by a plastic shaft sleeve provided at the upper end of each of the first tubular member and the second tubular member, and a separate locking mechanism is provided. It can be locked without the need for a lock, and will not come off during storage.

As described above, according to the present invention, the tubular member is locked by pushing the push plate and then moving the grip bar upward so that the tubular members are locked.
