  • Flexibility/rigidity adjustable apparatus
    Patent number: 8550989
    Abstract: There is provided a flexibility/rigidity adjustable apparatus which can change over its state between a flexible state in which such apparatus is freely bendable and a rigid state in which such bending is restricted when in use. A flexible closing cover 18 which can expand/shrink is provided on an outer circumference 2 of a flexible tube 1. A latching member 7 which moves together with the closing cover 18 is provided, and a latching-member receiving part 11 with which the latching member 7 can engage is provided at the outer circumference 2 of the tube 1. A closed space 21 formed between the closing cover 18 and the tube 1 is connected to an air inlet/outlet part 22. As the air is evacuated through the inlet/outlet part 22 to change the pressurized condition of the closed space 21 from an atmospheric pressure condition to a negative pressure condition, the closing cover 18 reduces its diameter around an axis 4, and the latching member 7 is caused to engage with the latching-member receiving part 11.
