Japanese Patent Application Laid-Open No. 2005-278943

  By the way, in the cane described in Patent Document 1, one end portion of the rubber cord is connected or connected to the upper end portion of the first pipe body. Therefore, the handle cannot be attached to the first pipe body unless the rubber string is connected to the upper end of the first pipe body. Further, even if the elastic force of the rubber cord deteriorates due to repeated use, the rubber cord cannot be easily replaced.

  Therefore, the present invention aims to provide a foldable cane that solves at least one of these problems.

  In order to achieve this object, the present invention is arranged between a first pipe body having a handle, a second pipe body having a stone bump, and between the first pipe body and the second pipe pair. And at least one intermediate pipe body, and an elastic coupling string (for example, a rubber coupling string) having one end connected to the first pipe body and the other end connected to the second pipe body. The elastic connecting string is held in a state where the first pipe body, the second pipe body, and the intermediate pipe body are connected in the length direction by the pulling force of the elastic connecting string, and the elastic connecting string is stretched, 1 is a foldable cane for disassembling and folding the first pipe body, the second pipe body, and the intermediate pipe body in a parallel state. A connection hole for connecting one end of Fitting is attached to it, the connection hole are those located to protrude from the opposite handle end of the first pipe. Here, for example, after fixing the connection fitting to the first pipe body and attaching the handle, the elastic connection string can be connected or connected to the connection hole of the connection fitting. Further, even when the elastic connection string deteriorates, the old elastic connection string can be easily replaced with a new elastic connection string.

  For fitting connection or fitting connection between pipe bodies, for example, one pipe body is provided with a small-diameter fitting portion so as to protrude from the end portion, and this fitting portion is fitted into the other pipe body. Is done. The connection between the first pipe body and the adjacent intermediate pipe body is achieved by projecting the connection fitting from the end opposite to the handle of the first pipe body and using the protruding portion of the connection fitting as a fitting portion. It can be carried out. However, since the outer diameter of the fitting portion is set to be substantially equal to the inner diameter of the pipe body so that the cane does not rattle during use, if the connection fitting is used as the fitting portion, the intermediate pipe is repeatedly inserted and removed. The end of the body (particularly carbon or resin intermediate pipe body) may be damaged by the connection fitting. Therefore, it is a good idea to provide a pipe-like fitting portion formed of carbon or resin in the first pipe body, and to fix the fitting by fitting the fitting to this fitting portion (a part of the first pipe body). is there. The connection hole of the connection fitting is positioned so as to protrude from the fitting portion.

According to the present invention, a foldable cane can be provided in which the degree of freedom in the order of attaching the elastic connecting strings during assembly is increased, or the deteriorated elastic connecting strings can be easily replaced.
