Abstract

A collapsible chair with a table is disclosed. In the collapsible chair, two collapsible chair units are arranged abreast on the chair with a gap being defined between them. A rear vertical guide column extends in parallel to the inside back support column of each collapsible chair unit. The two collapsible chair units are coupled to each other into the collapsible single body by two auxiliary connectors, which are individually mounted to the top portion of both the inside back support column and an associated vertical guide column of each collapsible chair unit. A movable guide member is received in each guide column in a way such that the guide member is movable in a vertical direction under the guide of the guide column. The table is movably coupled to the outside end of the guide members of the two collapsible chair units, thus being rotatable around the two guide members forwardly or backwardly. Two front vertical columns are individually provided at the inside corner of the front portion of each collapsible chair unit, thus supporting the front portion of the table in a horizontal position. An extension is provided at each auxiliary connector so as to allow the two auxiliary connectors to have the same height as that of the two front vertical columns. The two extensions thus support the rear portion of the table in the horizontal position.

Claims

1. A collapsible chair, comprising:

two or more collapsible chair units arranged abreast on the chair with a gap being defined between the chair units, said collapsible chair units being integrated with each other into a collapsible single body, each of the chair units further comprising front, rear, left and right X-shaped collapsible leg frames, a plurality of front and rear supports, a plurality of front and rear connectors, two back support columns, a back support member, a seat member, a pair of guide columns, a support wire and two auxiliary connectors;

said leg frames being coupled to each other at their upper and lower ends using said plurality of front and rear supports and said plurality of front and rear connectors, thus forming a collapsible chair framework with two back support columns being held by the two rear supports and the two rear connectors, said two back support columns supporting said back support member, each of the collapsible chair units also having said seat member supported by the front and rear connectors which respectively define the front and rear portions of the chair;

said guide columns being oriented vertically and being positioned in the back of the inside one of the two back support columns of each collapsible chair unit while extending in parallel to the back support column, each said guide column being fixed to the inside one of rear supports of adjacent chair units, with the collapsible chair units additionally being coupled to each other into the collapsible single body by the support wire, which is attached across the chair unit tops such as to encircle the tops of the two auxiliary connectors, which are vertically oriented and individually mounted to the top portion of both the inside back support column and an associated vertical guide column of each of the collapsible chair units;

a movable guide member received in each of the guide columns in a way such that the guide member is movable in a vertical direction under the guidance of said guide column, with a table being movably coupled to the outside end of the guide members of adjacent collapsible chair units in a way such that the table is rotatable around the two guide members forwardly or backwardly;

two front vertical columns individually provided at the inside corner of the front portion of each collapsible chair unit, thus supporting the front portion of said table when the table is positioned horizontally; and

an extension provided at each of the two auxiliary connectors so as to allow the two auxiliary connectors to have the same height as that of the two front vertical columns, thus supporting the rear portion of said table when the table is positioned horizontally.

2. The collapsible chair according to claim 1, wherein said table has a horizontal bar, with both ends of the horizontal bar meeting said two guide columns at right angles, said horizontal bar being brought into slidable engagement with the two guide members in a way such that the guide members are movable in opposite directions along the horizontal bar when the collapsible chair is opened or closed, said table also being rotatable around the two guide members forwardly and backwardly.

3. The collapsible chair according to claim 1, wherein an elastic support wire is horizontally provided on the rear edge of said table, said support wire being locked to a locking hole formed at each of the two auxiliary connectors when the table is fully collapsed into a vertical closed position, said support wire thus holding the table in said vertical closed position without allowing the table to be movable.

4. The collapsible chair according to claim 1, wherein each front vertical column has a top end and a locking cap which is fitted over the top end of each of said two front vertical columns, with a locking slot being formed at each side edge of the table at a position corresponding to each of the locking caps, said locking caps thus being fitted into the locking slots of the table and stably supporting the front portion of the table when the table is horizontally positioned at the gap between the collapsible chair units.

5. The collapsible chair according to claim 1, wherein a net bag, opened at its top, is removably provided at the gap between the collapsible chair units, said net bag having four hook rings at four corners of its top edge and being removably attached to both the two front vertical columns and the two inside back support columns at the four hook rings.
