Abstract
A dismantleable chair comprising a back member, leg members and a seat member all formed from generally two-dimensionally shaped materials such as plywood, and the like. The back member is somewhat arcuately shaped in both the horizontal and vertical cross-sections to provide superior seating comfort and strength. The arcuate shape also provides for a unique curved compressively pre-loaded joint design among the chair members, which substantially increases the strength and rigidity of the chair. The compressively preloaded joints are protected from bending and rotational loads by their respective positioning, and the presence of other spaced apart joints. The chair can be assembled and disassembled numerous times without loosing strength and rigidity.
Claims15
A dismantleable chair having a front portion and a rear portion, said chair made from members formed from generally two-dimensionally shaped materials, said chair comprising:
- a back member adapted at one end to provide support for said front portion of said chair, said back member having at least one close-ended slot extending therethrough,
- one leg member for each said close-ended slot, said leg members adapted to provide support for said back portion of said chair, each said leg member having a seat support edge and a back support edge, each said leg member extending through a corresponding said close-ended slot of said back member, said back member being attached to and compressively biased against each said back support edge;
- a seat member having a back mount edge, said seat member being attached to and compressively biased against said seat support edge of each of said leg members and being attached to and compressively biased against said back member along said back mount edge.
A dismantleable chair having a front portion and a rear portion, said chair made from members formed from generally two-dimensionally shaped flat materials, said chair comprising:
- a back member arcuately shaped in a horizontal and a vertical cross-section generally normal its said generally two-dimensional surface, said back member adapted at one end to provide support for said front portion of said chair, said back member having at least one close-ended slot extending therethrough,
- one leg member for each said close-ended slot, said leg members adapted to provide support for said back portion of said chair, each said leg member having a seat support edge and a back support edge, each said leg member extending through a corresponding said close-ended slot of said back member, said back member being attached to and compressively biased against each said back support edge;
- a seat member having a back mount edge, said seat member being attached to and compressively biased against said seat support edge of each of said leg members and being attached to and compressively biased against said back member along said back mount edge.
An erectable chair including panels that are approximately two dimensional, said panels being releasably assembled to one another, said erectable chair comprising:
- a primary panel that is approximately two dimensional, said primary panel having a back support portion and a load support portion, said primary panel having a closed seat panel engaging slot therein, and at least one closed leg panel engaging slot therein, said primary panel being adapted to extend approximately vertically;
- a seat panel that is approximately two dimensional, said seat panel being adapted to project generally horizontally, said back support portion being adapted to being disposed generally above said seat panel, and said load support portion being adapted to being disposed generally below said seat panel, said seat panel including at least one extension adapted to engage said closed seat panel engaging slot;
- at least one leg panel, said leg panel being approximately two dimensional, said leg panel being adapted to extend through said closed leg panel engaging slot and having a seat engaging portion, a load bearing portion generally opposed to said seat engaging portion, and a primary panel engaging portion, said seat engaging portion and said load bearing portion being adapted to being positioned on generally opposed sides of said primary panel, said leg panel extending approximately normal to said seat panel;
- a plurality of compression fastening members adapted to compressively and releasably join said respective panels together at respective compression loaded joints, said seat engaging portion and said seat panel being adapted to being compressively and releasably joined through a said compression loaded joint that is spaced from said closed leg panel engaging slot by at least about four inches, said primary panel engaging portion being adapted to being compressively and releasably joined to said primary panel through a said compression loaded joint that is spaced from said closed leg panel engaging slot, said.
