In addition, “hanging” is not limited to a mode in which the shelf is directly suspended, but is indirectly suspended such that the shelf is supported from any direction while being in contact with a separate object. It is a concept that includes a hanging mode.

  In such a case, the suspension shelf is suspended from the horizontal frame positioned below the seat, so that the front and rear ends of the shelf plate are suspended, so that the frame itself including the legs of the chair body is processed. It is possible to attach a “shelf” without any problems. In other words, it is effectively avoided to perform any special processing on the chair body in advance, so the problem that the above-mentioned processing location becomes conspicuous even if the hanging shelf is removed after introducing the chair with shelf is effective. Can be avoided. On the other hand, the present invention can also be realized without any special processing on an existing nestable chair. Furthermore, even when only a chair body that allows for the introduction of a shelf board is introduced, it is possible to effectively reduce the manufacturing effort of having to perform special processing in advance.

As an aspect of indirectly suspending a shelf board , the present invention includes a rear shelf suspension section integrally formed at the rear end of the shelf board, and a front shelf suspension section. The suspension part has a shelf support part that supports the shelf while being suspended from the horizontal frame and in contact with the front leg of the chair body.

As a specific configuration of the shelf support portion, the present invention provides a hook for hanging on the horizontal frame at the upper end of the shelf support portion and an abutment portion that contacts the leg frame at the lower end. The invention further abutment is characterized in that a hook portion that is hooked to the leg frame.

  And in the thing of such composition, if each suspension part which suspends the front-and-rear end of a shelf board shall be suspended from the same place in side view in a horizontal frame, it will become easy to attach to a chair main part, and existing Application to various chairs can be easily achieved. In this case, it is desirable that the shelf board support portion be capable of prohibiting the shelf board from swinging back and forth.

  And in order to make it easy to handle the luggage placed on the shelf as easy to handle from the side, it is necessary to position the suspension part along the leg of the chair body in side view. preferable.

  And in order to make a suspension shelf easy to apply to a chair main body, and to make it lightweight and highly durable, the shelf main body and the suspension portion may be formed of metal wires, respectively. desirable.

  According to the present invention, it is possible to attach a “shelf” to the frame itself including the legs of the chair body without performing any processing. In other words, it is effectively avoided to perform any special processing on the chair body in advance, so that the above-mentioned processed portion becomes effective even if the shelf is removed after introducing the chair with shelf. It is possible to provide a chair that can be avoided.
