  • Sectional type ironing board, as well as ironing table and pressing apparatus using said ironing board
    Patent number: 5161316
    Abstract: A sectional-type ironing board in which a longitudinal direction of a first ironing board and a longitudinal direction of a second ironing board having a working surface smaller than that of the first ironing board are oriented in the same direction, the first and second ironing boards are arranged in such a manner that side edges thereof are mutually adjacent, and the first and second ironing boards are independently movable to a collapsed state and an extended state relative to a common base. The first and second ironing boards are placed in the collapsed state or the extended state to form a joint working surface in the same plane, and the joint working surface is formed by a curved surface extending downwardly to edge portions from a central region along the longitudinal direction. An ironing table is used along with the sectional-type ironing board and includes a cart having a plate formed to have a portion on which the base portion of the sectional-type ironing board is placed and secured.
