Title:
SHAPE-LOCKING APPARATUS FOR A FLEXIBLE TUBE
Document Type and Number:
WIPO Patent Application WO/2012/070838
Kind Code:
A2
Abstract:
The present invention relates to a shape-locking apparatus for a flexible tube, which can control the slackened state and locked state of the flexible tube in an accurate and convenient manner. The shape-locking apparatus of the present invention comprises a plurality of joint rings, locking bars, connecting rods, detents, locking wires, and elastic members. The joint rings are arranged along the lengthwise direction of the flexible tube such that two adjacent joint rings adjacent are interconnected so as to be rotatable about a pair of pivots. The locking bars are arranged in the respective joint rings such that the locking bars pass through the respective joint rings and move along the lengthwise direction of the joint rings. The connecting rods are interposed between the respective joint rings and locking bars so as to connect the locking bars to the respective joint rings. The detents are arranged in the respective joint rings such that the detents are movable between a first position for arresting the operation of the locking bars and a second position for releasing the locking bars. The locking wires pass through the respective joint rings, and contact the respective detents so as to move the detents from the second position to the first position. The elastic members are arranged in the respective joint rings so as to move the detents from the first position to the second position. According to the present invention, the slackened state and locked state of the flexible tube can be controlled in an accurate and convenient manner by means of the rotation of the joint rings and the locking operation of the locking bars and detents. In addition, the joint rings are interlocked so as to accurately control the movement of a front end of the flexible tube in order to improve the operability of the flexible tube and firmly fix the flexible tube.
