Definitions

  • the present invention relates to a chair.
  • a chair In general, a chair is one piece of furniture for a person to sit on and includes a backrest, a seat and a leg.
  • Various types of these chairs have been invented depending on various conditions such as materials to be applied as well as usage and structures, and are widely used for students and office use.
  • FIG. 1 is a view schematically illustrating a conventional chair.
  • the conventional chair includes a leg 1 supporting from the ground, a seat part 2 on which a user's hip is seated, a backrest 3 supporting the back, wheels 4 provided in the leg 1 to apply movability, and armrests 5 provided at both sides of the seat part to support user's arms.
  • the seat part may be formed of a seat plate, and may also include a tilting device capable of tilting the backrest on the bottom surface of the seat plate.
  • the armrest for the chair is a device for comfortably supporting the user's arm when the user sits on the chair, and as illustrated in FIG. 1 , includes a supporter 6 vertically provided to both sides of the seat part 2, and a holder 7 made of a synthetic resin and the like while being installed horizontally in a front-rear direction on the upper end of the supporter 6.
  • An object of the present invention is to provide an armrest for a chair capable of receiving writing instruments as well as supporting the arm.
  • Another object of the present invention is to provide an armrest for a chair capable of holding a cup.
  • an armrest for a chair is an armrest for a chair provided on a seat part through a supporter and supporting a user's arm, which includes a receiving case for supporting the arm which is provided on the upper end of the supporter and elongated in a front-rear direction with respect to the seat part, and has an upper opening part; and an arm rest cover opening and closing the upper opening part and supporting the user's arm.
  • the armrest for the chair may further include a cup holder provided between the upper end of the supporter and the receiving case for supporting the arm and holding a cup.
  • the armrest for the chair may further include a case rotating part which rotatably provides the receiving case for supporting the arm on the cup holder so that the cup holder is covered or exposed to the outside by the receiving case for supporting the arm.
  • the cup holder may include a cup holder body having a plate shape, and one or more cup seating holes which are formed in the cup holder body to seat the cup.
