Abstract
A light-weight, weather-proof piece of lawn furniture is constructed of hollow rigid outer polyvinylchloride extrusions which are heated and pulled over metal rods forming members having the same shape as the metal rods. The metal reinforced polyvinylchloride extrusions are connected to form the frame of, for example, a chair. Straps are connected across portions of the frame to form a back and a seat of the chair.
Claims8
A light-weight, weather-proof lawn chair having improved strength, comprising:
- first and second arcuate hollow rigid outer plastic members each having two spaced-apart web members formed therein, said web members dividing the hollow interior of said first and second arcuate hollow rigid outer plastic members into three enclosed longitudinally-extending chambers separated from each other by said web members, said first and second arcuate hollow rigid outer plastic members forming front legs, back legs and arm portions of said chair;
- a third arcuate hollow rigid outer plastic member having an upper portion and a lower portion, said lower portion arranged at an angle to said upper portion, opposite sides of said third arcuate hollow rigid outer plastic member being connected across one of said first and second arcuate hollow rigid outer plastic members at two points, whereby opposite ends of each of said first and second arcuate hollow rigid outer plastic members form said front legs and said back legs of said chair and a portion of said first and second aracuate hollow rigid outer plastic members between said two points defining said arm portions of said chair;
- metal inner longitudinally-extending members having the same shape as and being located within one of said longitudinally-extending chambers of said first and second arcuate hollow rigid outer plastic members and within the hollow interior of said third arcuate hollow rigid outer plastic member to provide strength thereto;
- and
- a membrane connected between the sides of said third arcuate hollow rigid outer plastic member forming a back support of said chair at said upper portion and a seat support of said chair at said lower portion, said chair including a support member connected between the sides of said third hollow rigid outer plastic member, or between said legs, for maintaining the distance therebetween,
- wherein one of said metal inner longitudinally-extending members is located within each middle one of said longitudinally-extending chambers, and
- wherein said web members are integrally formed with said first and second arcuate hollow rigid outer plastic members.
