Description

  The present invention moves the table from the non-use position where the table hangs below the armrest to the use position which is substantially horizontal above the seat, on the armrest facing the front-rear direction provided at the upper ends of the left and right armrest struts. The present invention relates to a chair with a table that can be provided.

An example of this type of chair with a table is described in Patent Document 1.
Japanese Utility Model Publication No. 4-44137

  In the chair with a table described in Patent Document 1, the left and right side portions of the rear end of the seat are turned upward on the inner surfaces of the left and right pedestals (back support hardware) that also serve as armrest posts. Since it supports so that movement is possible, the support part of a right-and-left pedestal and a seat will be located ahead relatively with respect to a seat.

  For this reason, when the table pivotally attached to the front end of one armrest is in a non-use position where it hangs down below the armrest, the depth of the table is such that the rear end does not contact the front surface of the pedestal. Need to be restricted. If it becomes like this, the front-back dimension when a table will be in a horizontal use state will also become small, and usability will worsen.

  In order to cope with this problem, it is conceivable that the front and rear dimensions of the armrest are made large and a table is pivotally attached to the front end of the armrest as much as possible, but in this way, when installing a plurality of chairs side by side, The passage formed between the front and rear chairs becomes narrow and hinders walking.

  In the chair with a table described in the above-mentioned patent document, the table receiving member that holds the table in a horizontal use position is attached to the inner side surface of the armrest mounting portion facing forward in the armrest strut, and the dimensions in the front-rear direction are compared. Therefore, the side surface of the seated person may come into contact with the table receiving member, so that a comfortable sitting comfort may not be obtained, and the appearance is poor.

A non-use position where the table is suspended in front of the armrest strut and below the armrest by pivotally attaching one side of the table to a second pivot that faces in a direction orthogonal to the first pivot. The first pivot is pivoted forward and upward about the first pivot, and is pivoted downward about the second pivot so that it can be moved to a use position that is substantially horizontal above the seat. In the chair with a table, the leg body is provided with a pair of left and right seat support brackets projecting forward from the armrest struts, and the seat is supported by the front portions of the both seat support brackets. The rear edge of the table So that can be positioned behind the support part of the seat by serial seat support bracket.

  (2) In the above item (1), the armrest support column is tilted rearward so that the corner portion on the upper rear side of the table in the non-use position enters into the corner portion formed in the connecting portion between the armrest column and the armrest.

  (3) In the above (1) or (2), the inner surface of the front end of the armrest is recessed outward, and the side end of the table is pivotally attached to the recessed inner surface by the first pivot.

According to the first aspect of the present invention, the seat is supported by the front portion of the seat support bracket projecting forward from the armrest strut, and the rear end of the table in the non-use position is located behind the support portion of the seat. By being able to do so, the depth dimension in the non-use position in a table can be enlarged.
As a result, the front and rear dimensions of the table at the use position are increased without increasing the length of the armrest, and usability is improved.

  According to invention of Claim 2, the depth dimension of the table in a non-use position and the front-back dimension of the table in a use position can be enlarged more.

  According to the invention of claim 3, since the pivoting portion by the first pivot of the table in the non-use position does not protrude inwardly, that is, the seat side, the possibility of coming into contact with the side surface of the seated person is reduced. Sitting comfort improves and looks better.
