Claims9
A utility trench and carpet cover system in which the carpet covering the trench is not set out from the remaining carpet and in which the trench can be accessed without damage to the carpet comprising
- a. a floor,
- b. a utility trench having an open top formed in the floor and having recessed shoulders adjacent to the top of said trench,
- c. at least one trench cover plate positioning on said shoulders to cover the trench, the cover plate having a support flange positioned on one lateral edge with a portion of the flange secured to the underside of the plate and a portion extending outwardly from said plate for supporting the center of the next adjacent plate, a notch in the flange intermediate its ends and a longitudinally aligned notch in the opposite lateral edge of the cover plate whereby when cover plates are laid end to end the notches coincide,
- d. bracket means around three edges of said cover plate, and
- e. a carpet segment secured to the plate within said bracket means,
- f. whereby a tool is insertable into said alignment notches for lifting the plate off of the trench without damaging the carpet attached to the plate.
A utility trench and carpet cover system having both rectangular and round access openings to the trenches in which the carpet covering the trenches is not set out from the remaining carpet and in which the trenches can be accessed through the access openings without damage to the carpet comprising
- a. a floor,
- b. longitudinal utility trenches having an open top formed in the floor and having recessed shoulders adjacent to the top of said trenches,
- c. rectangular trench cover plates positioning on said shoulders to cover the trenches, the cover plates each having a support flange positioned on one lateral edge with a portion of the flange secured to the underside of the plate and a portion extending outwardly from said plate to support the center of the next adjacent plate, a notch in the flange intermediate its ends and a longitudinally aligned notch in the opposite lateral edge of the cover plate whereby when the cover plates are laid end to end the notches coincide,
- d. bracket means around three edges of said cover plate, and
- e. a rectangular carpet segment secured to each of the cover plates within said bracket means, whereby a tool is insertable into said alignment notches for lifting the plate off of the trench without damaging the carpet attached to the plate.
