2. Description of the Related Art Conventionally, as a structure of a hanging hand in a vehicle, a flat hanging belt made of cloth, leather, resin or the like is used, and a loop is formed at the upper end of the hanging belt, and this loop portion is used in the vehicle. While hanging on a hanger support rod (a hanger support pipe) that is laid horizontally on the side, while connecting various annular shaped hand parts to the lower end of the hanger belt, both ends of the hanger belt are polymerized, and this polymerization Both sides of the part are sandwiched by seat plates and fixed by screwing with fastening screws, or both ends of the hanging belt hung on the hanging hand support rod are inserted above the hanging part instead of the above hanging part. Forming a locking groove for inserting the lower end portion of the hanging belt into the engaging groove, screwing both with a screw in the inserting portion, the screw penetrates the lower end portion of the hanging belt inserted in the inserting portion In this way, a structure in which the suspension belt is connected to the handle portion is common.

However, each of the above configurations of the lifting hand is uneconomical because the hanging belt material is polymerized to form a double structure, resulting in excessive quality characteristics, and both ends of the hanging belt are fastened. Auxiliary means such as a seat plate, a fastening screw, and a sheath are required, and complicated work is required for the machining, mounting, and removal. Therefore, the present inventor has paid attention to the above-mentioned drawbacks, and previously proposed a connection structure of the suspension belts in which the suspension belts have a single structure so that they can be easily attached to the suspension bar. (See Japanese Patent Publication No. 7-75950)

[0004]

However, in each of the above-described conventional hanging hand structures, since a hanging belt made of cloth, leather, or resin is used as the hanging belt, cutting these hanging belts, Problems such as damage have arisen, and it is necessary to deal with this, and it has been considered to use metal or a strength member having the same effect as the material of the hanging hand.

The present invention responds to such recent trends, and in particular, provides a novel connecting structure of a lifting member by using a strength member such as metal as a material of the lifting member, and cutting the lifting member, The purpose of the present invention is to prevent the damage due to breakage, to simplify the attachment and detachment of the lifting hand member, and to improve the safety inside the vehicle.

[0006]

The short pipe member is made of a flexible member, and the upper end of the hanging member is inserted into the short pipe member having a small diameter and capable of being inserted into and removed from the hanging pipe support pipe through a through hole provided in the peripheral surface thereof. Along with locking and holding, a handhold is attached to the lower end, and the short pipe member is inserted into the hanging pipe support pipe in a state where the hanging pipe member is extended from the hanging pipe member mounting groove on the lower surface, Hold the above short pipe material at the position and support the hanging member. It was ligated to the type.

As a flexible member made of metal or a material having the same effect, a flexible member in which a twisted wire of a metal wire is used as a core material and which is covered with a spiral pipe member made of metal such as stainless steel is the most general.

Further, the present invention is also characterized by a connecting method for forming the above-mentioned connecting structure, in which a hanging member support pipe laid horizontally in a vehicle is formed of a flexible member made of a metal or a similar material. When connecting the upper end of the hanger member having the handle portion attached to the lower end, a mounting groove for the hanger member is formed along the longitudinal direction on the lower peripheral surface of the hanger support pipe, while the upper end of the hanger member is The short pipe material having a small diameter, which can be inserted into and removed from the hanging hand support pipe, is inserted through a through hole provided on the peripheral surface to be retained and locked and a handle portion is attached to the lower end of the short pipe material. It is characterized in that the hanger member is inserted into the hanger support pipe by being slid from the side in a state where the hanger member is extended from the hanger member mounting groove on the lower surface, and is connected to the short pipe at a predetermined position.

[0009]

According to the above-described connecting structure of the present invention, since the handle member is made of metal or a material having the same strength, it has strength unlike the conventional flat belt made of cloth, leather or resin. It is not easily cut and has excellent durability, and the upper end of the lifting member is fastened to this using a short pipe material, and the short pipe material is inserted into the lifting hand support pipe. Since the position of the hanger member is determined and held, the mounting operation is very easy.
