Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is a so-called portable carrier that is capable of easily carrying luggage carried during travel, for example, supporting a handle of the portable carrier. The present invention relates to a support release device for a portable carrier.

 2. Description of the Related Art For example, Japanese Patent Laid-Open No. 52-59437 (a telescopic assembly for a portable baggage carrier) is known as a portable carrier of this type that is carried during traveling and is capable of easily carrying luggage. is there.

 In the handle part of the carrier, the pipe parts forming a pair of handle parts are formed of three pipes (corresponding to the support device of the handle in the present invention), and each pipe is fitted to an adjacent pipe so that it can be expanded and contracted. It was done.

 The locking means of the adjacent pipe is performed by an elastically urged engaging element that is biased by a spring, and a sliding member provided with two tapers on both sides to engage with the engaging element is provided at an intermediate position between the adjacent pipes. The lock of each engaging element is released by moving the sliding member up and down. Therefore, at this time, the support portion of the handle can be reduced while pushing down the handle.

 Problems to be solved by the invention Since the sliding member for releasing the engaging element that blocks the movement of the adjacent pipe is located at the intermediate position of the handle portion, a tall person can use this sliding member for releasing the releasing member. When operating it, you have to bend your hips or become a middle waist, which makes it difficult to perform the removal operation in crowded or narrow places.

 The object of the present invention is to eliminate such drawbacks by allowing the first engaging element to be released in a standing posture and with one hand holding the first handle, and the structure is simplified and stable. It is to be able to operate.

 Means for Solving the Problems In order to achieve such an object, the present invention pulls up a second handle that slides along the first handle to move the second handle and the first pipe. In a support release device for a portable carrier in which the fixation of the first pipe and the second pipe is released, the first handle fixed to the upper ends of the pair of first pipes, and the first handle in the direction of the first handle. A second handle that moves, a spring member that is located between the first handle and the second handle and that urges the second handle downward, and a bent inclined portion that is inserted into one end of the first pipe. A wire rod which is formed and whose other end is fixed to both ends of the second handle, and a bent slope portion of the wire rod is engaged with a flange portion of the rear end portion and is biased by a spring of the rear end portion. A small hole in the lower part of the pipe and a first engaging element that goes into the small hole in the upper part of the second pipe are provided and slide along the first handle. When pulling up the second handle, the bent slanted portions of the wire fixed to both ends of the second handle engage the first engaging element with the first pipe adjacent to the first pipe while engaging the collar portion of the rear end. The reason is that it can be retracted in the direction of the first pipe through the small holes of the two pipes.

 Action When pulling up the second grip that slides along the first grip, the bent slanted portions of the wire material that are fixed to both ends of the second grip engage the flanges of the rear end while engaging the first engaging element. Can be retracted in the direction of the first pipe from the small holes of the adjacent first and second pipes, so that the first handle is pushed downward and at the same time the first pipe fits into the second pipe. It is inserted to reduce the support of the first handle.

 Embodiment An embodiment of the present invention will be described below with reference to the drawings.

 FIG. 1 is a vertical cross-sectional view of a main part of a carrier C that supports a first handle and a second handle.

 Both ends a'of the first handle Aa are fixed to the upper ends of the pair of first pipes 1A.

 A second handle Ab is provided which moves upward along the long hole Aa 'of the first handle Aa and has both ends b'at the upper end of the first pipe 1A.

 A spring member S is provided which is located at an intermediate portion H between the first handle Aa and the second handle Ab and biases the second handle Ab downward.

 The wire 1 forming the bent inclined portion 1a 'is fitted into the first pipe 1A at one end 1a, and the other end 1b of the wire 1 is fixed to both ends b'of the second handle Ab.

 The flange 3 of the rear end portion 2 ′ of the first engaging element 2 is engaged with the bent inclined portion 1 a ′ of the wire 1.

 The tip 2 ″ of the first engaging element 2 enters into the small hole 4 provided in the lower portion of the first pipe 1A and the small hole 5 provided in the upper portion of the second pipe 2A, and the adjacent first pipe 1A and second pipe 1A. When the 2 grip 2A is pushed down so as to prevent the movement of 2A, the bent slanted portion 1a 'of the wire rod S'inserted in the 2nd grip 2A is the rear end portion of the first engaging element 2. Retracting the first engaging element 2 from the small hole 4 of the first pipe 1A and the small hole 5 of the second pipe 2A, which are adjacent to each other, in the direction of the first pipe 1A while engaging with the collar portion 3 of 2 '. Therefore, the first pipe 1A can be inserted into the second pipe 2A.

 FIG. 2 is an overall perspective view of the carrier C, which shows a first handle Aa fixed to the upper ends of the pair of first pipes 1A and a bar provided at an intermediate portion facing the first handle Aa. A second handle Ab that is urged downward by the rod member S and can slide upward and downward is provided.

 The pair of support bodies Y supporting the first handle Aa and the second handle Ab are extendable.

 That is, the first pipe 1A is sequentially provided in the second pipe 2A, and the second pipe 2A is provided in the third pipe 3A so as to be sequentially extendable from above.

 The pair of support bodies Y are arranged so that they can be expanded and contracted so that they can be sequentially loaded from the top when the luggage is placed.

 Below the pair of supporting bodies Y, a load receiving base B for placing a load is provided.

 Wheels R are attached to both ends of an axle R'provided at the bottom of the cargo receiving stand B.

 Effect of the Invention As described above, according to the present invention, by pulling up the second grip that slides along the first grip, the second grip moves and the fixation of the first pipe and the second pipe is released. In a support releasing device for a portable carrier configured as described above, a first grip fixed to the upper ends of a pair of first pipes, a second grip that moves in the direction of the first grip, and a first grip. And a spring member that is located in the middle of the second handle and urges the second handle downward, and is inserted into the first pipe to form a bent inclined portion at one end and the other end at the second handle. A wire rod fixed to both ends and a bent slope portion of the wire rod are engaged with a flange portion of the rear end portion, and are biased by a spring at the rear end portion, and a small hole under the first pipe and the second pipe. The second grip that slides along the first grip is pulled up by providing the first engaging element that goes into the small hole in the upper part of the When the bending operation is performed, the bent inclined portions of the wire material that are fixed to both ends of the second grip engage the first engaging element with the small holes of the first pipe and the second pipe that are adjacent to each other while engaging the flange portion of the rear end portion. Since the wire can be retracted in the direction of the first pipe, the intended purpose is achieved, and the wire rod that is easy to process is used, the cost is low, and the spring member provided in the middle part of the first handle In addition, the second handle can be stably pulled up, and has practically excellent effects.
