Fiberglass footbridge

Claim 2

A footbridge suspended between a support at each end, comprising: a horizontal layer of nonmetallic fibers connected between the supports to define a floor for pedestrians, with a continuous layer of nonmetallic filaments formed in the floor, each filament extending substantially parallel with the length of the floor; a pair of nonmetallic fiber handrails spaced laterally apart and disposed above the floor, each handrail having a continuous layer of nonmetallic filaments extending substantially parallel with the length of the handrails; and two webs of nonmetallic fiber, each mounted perpendicular to the floor and connecting the floor with one of the handrails substantially along the length of the footbridge.

Claim 3

The footbridge according to claim 1 wherein the continuous filaments in the floor are disposed on each side of the floor adjacent its connection with the webs.

Claim 4

The footbridge according to claim 1, further comprising: at least one U-shaped supporting member mounted to the footbridge intermediate its ends, the supporting member having upright legs connected to the exterior sides of the webs and a base connected to the lower surface of the floor.

Claim 5

The footbridge according to claim 3 wherein the footbridge contains at least two supporting members spaced apart along the length, with a subfloor mounted below the floor between supporting members.

Claim 6

The footbridge according to claim 1 wherein nonmetallic fibers in the floor, handrails, and webs comprise layers of woven fiberglass and layers of fiberglass mat, and wherein the continuous filaments are fiberglass filaments

Claim 7

A fiberglass footbridge suspended between a support at each end comprising: a horizontal layer of fiberglass connected between the supports to define a floor for pedestrians, with a continuous layer of fiberglass filaments formed on each side edge of the floor and extending substantially parallel with the length of the floor; a pair of fiberglass handrails spaced laterally apart and disposed above the floor, each handrail having a continuous layer of fiberglass filaments extending substantially parallel with the handrails; two webs of fiberglass, each mounted perpendicular between the floor and one of the handrails and extending substantially the length of the footbridge; a plurality of U-shaped supporting members spaced along the length of the foorbridge intermediate its ends, the supporting members having upright legs connected to the exterior sides of the webs and a base connected to the lower surface of the floor; and a subfloor mounted below the floor by vertical sides in the same plane and extending between the supporting members.
