TENSION TYPE COLUMN
Document Type and Number:
Japanese Patent JP2016125631
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tension type column capable of applying tension to a column body only through treading of an operation pedal and fixing the column body and enabling everybody including powerless person to perform a comfortable and fast installation of the column.SOLUTION: A tension type column comprises: a column body 1 including a ceiling side pipe 4 and a floor side pipe 5; a telescopic lock unit 6; a ceiling base 2; and a tension structure 3. The tension structure 3 comprises: a fixing base 21; a lift mechanism for ascending or descending the floor side pipe 5; and a lock mechanism for locking the floor side pipe 5 at its tension position in such a manner that the floor side pipe may not be descended. The lift mechanism includes: a lift pin 44; an operation pedal 45 connected to the lift pin 44; and a pedal supporting body 46 for accepting a treading force of the operation pedal 45. Upon treading the operation pedal 45, the operation pedal 45 oscillates around the lift pin 44 while receiving a treading reaction force from the pedal supporting body 46 to lift up the floor side pipe 5. A member going together with the ascending floor side pipe 5 is engaged with the lock mechanism to lock and held the column body 1 in its tension state.SELECTED DRAWING: Figure 1
