Description

  The present invention relates to a chair with a table.

  For chairs that are placed in various locations in meeting rooms and halls and used by many people, a table that is large enough to hold a laptop computer, etc. It is convenient if attached. However, if the table of such a size is simply fixed to the chair, the table becomes an obstacle when sitting and standing.

In a sofa with a low seat height, an arm that can be swiveled on a horizontal surface is mounted at a low position on the lower surface of the seat so that it can be straddled when it crosses the leg of a person sitting on it even if the arm is swiveled. In addition, by attaching a single leg table that can be rotated on the floor to the tip of this arm, the table can be rotated left and right so that it does not get in the way when sitting and standing, and the table itself can be placed horizontally. Proposals have been made so that the personal computer can be operated in various postures by enabling it to turn in a direction (see Patent Document 1).
Japanese Patent No. 3108779

  However, in the device described in Patent Document 1, the arm protruding from below the seat part obstructs the seated person, and the front part of the seat part cannot be completely opened, and is inconvenient to transport and store. It is not suitable for use in a meeting room.

In view of the above circumstances, the present invention is capable of stably supporting the top plate of the table without being in the way of taking off and sitting , and by enabling nesting of a plurality of chairs with the same shape , The object is to provide a chair with a table that can be easily stored.

According to the present invention, the above problem is solved as follows.
(1) After extending outwardly on either the left or right side of a pair of left and right leg frames consisting of a front leg collar and a rear leg collar that support the seat, it extends obliquely forward and upward. A fixed arm is provided, and the distal end of the fixed arm is a pivot that faces in the vertical direction. With this pivot, a table frame composed of a pair of left and right legs that are in contact with the lower end is attached to one of the left and right sides of the table frame . A top plate supported by the table frame and pivoted with a movable arm extending laterally from the toe is rotated between a use position located in front of the seat and a deployed position located on the side of the seat. When the distance between the left and right front leg heels and the rear leg ridges in the leg frame is formed so as to expand rearward, and the top plate is in the deployed position. The movable arm and fixed arm are flat. The top plate is pivotally attached to the table frame so as to be pivotable about a left-right axis at the unfolded position, and is almost horizontal. The seat can be pivoted to a vertical position and a vertical position, and the seat is pivotally attached to the rear part of the leg frame with a horizontal axis. It can be rotated to the position .

(2) In the above item (1), the table frame has a pair of left and right legs each having a caster that can roll in a non-directional manner on the floor surface.

( 3 ) In the above item (1) or (2) , the table frame is directed horizontally from the left and right sides of the horizontal frame to which the top plate is pivoted, and from the both ends of the horizontal frame toward the front when it is in the unfolded position. A pair of left and right side supports that support the lower surface of the top plate when extended and set to the lying position, and a pair of left and right leg supports that are suspended from the front ends of both sides and have casters at the lower ends. Shall be provided.

The invention described in each claim has the following specific effects.
(1) Claim 1: By rotating the top plate of the table from the use position in front of the seat to the deployed position on the side of the seat, the front of the seat can be completely opened. The seated person can freely leave and set up without being obstructed by the table.
Moreover, since the lower end of the table frame is in contact with the floor, the top plate can be stably supported both in the use position and in the deployed position.
In addition, a movable arm that extends laterally from one of the left and right leg rods of the table frame is provided at one of the left and right sides of the leg frame at the tip end portion of the fixed arm that extends outward. By pivoting, since the table frame is pivoted, the pivot portion can be separated from the leg frame laterally. Thereby, a top plate can be separated from a seat at the time of deployment, and it can prevent a top plate from interfering with a seated person's seat.
Further, the fixed arm extends obliquely forward and upward, and the movable arm and the fixed arm have a V-shape that expands rearward in a plan view when the top plate is in the unfolded position. Therefore, when the leg frame and the connecting portion between the table frame and the leg frame in the deployed position are overlapped in the front-rear direction with a plurality of table chairs having the same shape, It can be condensed and stored in the front-rear direction so that the parts fit each other.
As a result, at the unfolded position of the table, the top plate is flipped up to the standing position and the seat is in the flipped-up position, so that a plurality of chairs with the same shape can be nested, and the depth dimension in the front-rear direction is limited. In a narrow storage space, it can be stored in a compact manner by stacking in the front-rear direction, and transportation is also facilitated.

(2) Claim 2: The load applied to the top plate can be received by a pair of left and right legs that are in contact with the floor, and the fall of the legs is pivoted to the leg frame with the pivot axis of the table frame facing up and down. It is prevented by being worn, and the top plate can be stably and strongly supported.

( 3 ) Claim 3 : The table frame can be manufactured easily and inexpensively by bending one pipe or bar, and the top plate can be stably supported.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
