Stackable side-by-side ganging chair

A stackable ganged chair that is capable of side-by-side orientation with one or more additional chairs in side-by-side relationship comprising:

• a chair frame having an upper frame, and a lower frame, said upper frame adapted to receive and support a seating platform thereon, said upper frame having a front side, a first side and a second side, each of said first and second sides having rear ends attached to a backrest platform for supporting a user seated in the ganged chair,
• said lower frame having first and second sides supporting said upper frame above a supporting surface for the chair,
• said lower frame including left front and left rear leg members disposed on said first side of said lower frame, and right front and right rear leg members disposed on said second side of said lower frame, each of said leg members having a lower end adapted to engage the supporting surface for the chair, and each of said leg members having an upper end,
• said lower frame further including:
• a front cross-member connected between said upper ends of said left front leg member and said right front leg member, said front cross-member positioned proximally underneath said upper frame,
• a rear cross-member connected between said upper ends of said left rear leg member and said right rear leg member, said rear cross-member positioned proximally underneath said upper frame,
• a left side connector member extending between and fixedly interconnecting said upper ends of said left front and left rear leg members to one another,
• a right side connector member extending between and fixedly interconnecting said upper ends of said right front and right rear leg members to one another,
• said left side and right side connector members generally occupying a common plane,
• a left side coupling support positioned above and onto said left side connector member, said left side coupling support having a left extension with a coupling hook extending laterally from said left extension, said coupling hook occupying said common plane, and
• a right side coupling support positioned above and onto said right side connector member, said right side coupling support having a right extension with an interior, downward opening, slot aligned parallel with said right side frame member,
• whereby said left side coupling hook of the ganged chair is insertable into a slot of said right extension of a second ganged chair of similar dimensions,
• whereby said chair frame is stackable on top of another stackable ganged chair.

An improved stackable chair that is capable of being ganged with a chair in side-by-side relationship, comprising a chair platform having an upper frame having a front side, a right side, and a left side, said upper frame including:

• a seating platform, said seat platform having a seat pad detachable above said upper frame, and a backrest platform, said backrest platform angled backward from the vertical position;
• wherein the improvement comprises:
• a lower frame having a left side and a right side supporting said upper frame above a supporting surface for the chair;
• a chair leg structure attached to said lower frame, said leg structure including:
• a left frame member connected to said left side, said left frame member having left front and left rear legs connected at said upper end of said frame member, each of said left legs having an upper front end and upper rear end,
• said front left leg connected to said upper front end of said left side frame member;
• and
• said rear left leg connected to said upper rear end of said left side frame member;
• a right side frame member connected to said right side, said right side frame member having a right side pair of legs connected at the corner ends of said frame member, said pair of legs including:
• a front right leg connected to the front corner end of said right side frame member;
• and
• a rear right leg connected to the rear corner of said right side frame member;
• a front cross-member connected between the front left corner end of said left side frame member, and connected to the front right corner end of said right side frame member, said front cross-member positioned under said seat platform, said front cross-member is parallel with the front frame tube of said chair platform;
• a rear cross-member connected to said rear left corner end of said left side frame member, and connected to said rear right corner end of said right side frame member, said rear cross-member positioned under said seat platform, said rear cross-member positioned behind said front cross-member and under said chair platform, said rear cross-member is parallel with said front cross-member;
• and
• a left side and a right side coupling support, said left side and said right side coupling supports generally occupying a common generally horizontal plane which effectively defines the upper limits of said first and second sides of said lower frame, said left side coupling support having a left extension with a coupling hook extending laterally from said left extension, said coupling hook occupying said common plane, said right side coupling support having a right extension with an interior, downward opening, slot aligned parallel with said right side frame member;
• whereby said left side coupling hook of the ganged chair is insertable into a slot of a right extension of a second ganged chair of similar dimensions;
• whereby said chair is stackable on top of another chair structure.

A chair having which is stackable and capable of being ganged with one or more additional chairs comprising

• a frame, including
• a first set of front and rear leg members defining a first side of said frame, each leg member having a top and a distal end,
• a first connector member extending between and interconnecting said top ends of said front and rear leg members of said first set of front and rear leg members, said first connector member including a side surface which faces outwardly of the chair,
• a second set of front and rear leg members defining a second and opposite side of said frame, each leg member having a top and distal end, and
• a second connector member extending between and interconnecting said top ends of said front and rear leg members of said second set of front and rear leg members, said second connector member including a side surface which faces outwardly of the chair,
• said first and second elongated connector members generally occupying a common generally horizontal plane which effectively defines the upper limit of said first and second sides of said frame,
• a connector lug disposed on and projecting outwardly from said outwardly facing surface of said first connector member and including an upstanding flange projecting upwardly from the outboard end of said lug to define a space between said flange and said side surface of said first connector member, said connector lug occupying said common plane, and
• a receptacle disposed on and projecting outwardly from said outwardly facing surface of said second connector member and defining a downwardly opening slot, said receptacle occupying said common plane, and being suitable for the receipt of an upstanding flange of a connector lug of another chair therein,
• whereby when a first one of the chairs is disposed with its connector lug adjacent a second one of the chairs and with the receptacle of the second chair in register with the flange of the connector lug of the first chair, the first and second chairs are interconnectable by insertion of the flange of the connector lug of the first chair into the receptacle of the second chair and said interconnection is disposed within said common plane.
