Definitions

  • the present invention relates to a chair, and particularly to a chair having a backrest to which an optional member is attached.
  • a conventional chair has a backrest to which an optional member such as a hanger for hanging clothes, a headrest, or the like, is attached (for example, see Patent Literatures 1 to 5).
  • the present invention has been made in consideration of the above-described problems, and an object of the present invention is to provide a chair capable of stably and securely mounting an optional member on a backrest with a simple structure, easily adjusting a mounting position of the optional member in an upward/downward direction, and maintaining a good appearance of the backrest after the optional member is dismounted.
  • the optional member since the portions of the mounting members of the optional member are engaged with the grooves formed in the left and right sides of the backrest, the optional member can be stably and securely mounted with a simple structure. Even when the optional member is disposed at any position (height) along the grooves, the optional member can be mounted with the same structure. Thus, a mounting position of the optional member in an upward/downward direction can be easily adjusted. In addition, after the optional member is dismounted, since no element of the mounting structure such as a screw hole, etc., remains, a good appearance of the backrest is maintained.
  • the concave grooves formed in the front and the rear of both sides of the backrest are in alignment with each other in a forward/rearward direction so that horizontal cross-sections of both sides of the backrest have a substantially "H" shape.
  • the mounting members of the optional member can be inverted in a forward/rearward direction to be mounted, and mounting aspects of the optional member can be diversified.
  • Concave grooves recessed rearward and oriented in an upward/downward direction are formed in a front surface of a backrest, and portions of mounting members installed at both sides of an optional member are engaged with the concave grooves to mount the optional member on the backrest.
  • the concave grooves with which the portions of the mounting members of the optional member are engaged are specified to be in the front surface of the backrest, the same operations and effects as the invention of the aspect (1) can be accomplished.
  • Concave grooves recessed forward and oriented in an upward/downward direction are formed in a rear surface of a backrest, and portions of mounting members installed at both sides of an optional member are engaged with the concave grooves to mount the optional member on the backrest.
  • the concave grooves with which the portions of the mounting members of the optional member are engaged are specified to be in the rear surface of the backrest, the same operations and effects as the invention of the aspect (1) can be accomplished.
  • any one of upper and lower ends of the concave grooves in the backrest is blocked by a blocking piece.
  • the blocking piece can prevent the mounting members of the optional member from being separated upward or downward from the backrest.
  • the backrest comprises a pair of left and right side rods and a back plate connecting the side rods and having a forward/rearward directional thickness smaller than that of both of the side rods, and the concave grooves are formed on both of the side rods.
  • the left and right side rods and the back plate can be integrally formed using the same material and the back plate can have flexibility.
  • convex portions or concave portions are formed in inner surfaces of the concave grooves, and the portions of the mounting members are engaged with the convex portions or the concave portions.
  • a plurality of convex portions or concave portions are formed in the inner surfaces of the concave grooves at predetermined intervals in the upward/downward direction, and the portions of the mounting members are selectively engaged with the convex portions or the concave portions, so that the optional member is installed at the backrest in the upward/downward direction in a manner capable of adjusting a mounting position.
  • mounting positions of the optional members can be adjusted to a plurality of heights.
  • the mounting members of the optional member comprise surrounding pieces extending outward from side ends of the optional member and surrounding side ends of the backrest, elastic members installed at the surrounding pieces, and engaging claws installed at ends of any one of upper and lower front ends of the surrounding pieces and fitted to the concave grooves of the backrest to be selectively engaged with the plurality of convex portions or concave portions formed in the concave grooves, so that the optional member can be locked to the backrest at the plurality of heights, and wherein the engaging claws are biased by the elastic members in a direction of engaging the mounting members with the convex portions or the concave portions with respect to the backrest, so that the engaging claws can be separated from the convex portions or the concave portions by moving the optional member against the biasing force.
  • the engaging claws are separated from the convex portions or the concave portions. In this state, after moving the mounting members along the concave grooves upward and downward, as the engaging claws are engaged with another of the convex portions or concave portions, the mounting position of the optional member can be simply changed.
  • the mounting members of the optional member comprise surrounding pieces extending outward from side ends of the optional member and surrounding side ends of the backrest and elastic members installed at the surrounding pieces, at least one of the front ends of the surrounding pieces and the elastic members is engaged with the concave grooves of the backrest, and the side ends of the backrest are sandwiched by the front ends of the surrounding pieces and the elastic members.
  • the optional member is any one or a plurality of a hanger for hanging clothes, a headrest, an armrest, and a lumbar support.
  • one or more of the optional members having different functions can be simply installed at the backrest as a single or a combined assembly, diversifying the chair.
  • the chair in which the optional member can be stably and securely mounted with a simple structure, and the mounting position of the optional member in the upward/downward direction can be easily adjusted, and further, after the optional member is dismounted, a good appearance of the backrest can be maintained.
