Description

  TECHNICAL FIELD The present invention relates to a wiring / pipe material bending posture maintaining tool for inserting a bent portion of a wiring / pipe material into the inside and maintaining the bending posture.

  As used herein, the term “locking structure” refers to a portion that can be locked so that a locking portion of a specific member and a corresponding locked portion do not come off from each other. The “locking structure portion” is a concept including both the locking portion and the locked portion, and includes both a state in which the locking portion and the locked portion are locked and a state in which the locking portion is not locked. Will be included.

  As a conventional curved posture maintaining device having a cylindrical shape by being continuously provided in the axial direction, a device disclosed in Patent Document 1 is known. In this bending posture maintaining tool, a notch is formed at a specific portion along a circumferential direction at a predetermined interval along an axial direction of a cylinder main body, and a wiring / pipe material is formed from one end of the cylinder main body in an axial direction. By bending the wiring / piping material together with the cylinder main body in the inserted state, the locking portion and the locked portion provided at the facing portions of the notches are locked with each other, so that the pipe This is a configuration for maintaining the bent state of the main body.

  For this reason, the above-mentioned bent posture maintaining tool needs to bend the wiring / piping material and the cylinder body together after inserting the wiring / piping material in advance, and the wiring / piping material is bent in advance. In this state, it is impossible to insert the bent portion of the wiring and piping material into the inside of the cylinder body, so that the order of each wiring and piping process is restricted, and the degree of freedom of the wiring and piping material is reduced. was there. In addition, since the portion of the cylinder body facing the notch portion is continuous, the cylinder body attempts to return to its original linear shape in a state where the cylinder body is bent by the locking. Since the force acts, there is also a problem that the locking is released by the restoring force.
