  • Column unit
    Publication number: 20040079854
    Abstract: A column unit is disclosed, in which a guide sleeve is adhered to the external surface of a spindle by an adhesive for metal, thereby allowing the spindle to stably perform a long stroke. The column unit provided with a spindle that moves up and down in a base tube to adjust the height of chair or table includes a cylindrical shaped guide sleeve fixed onto the external surface of the spindle from an upper portion of the spindle to a height lower than its lower portion, moving up and down along with the spindle, and an adhesive layer applied between the guide sleeve and the spindle to fixably adhere the guide sleeve to the spindle. Therefore, the stroke length of the spindle can stably be increased and the adhesive is simply used to adhere the guide sleeve to the spindle, thereby saving the cost for mass production.
