Raisable platform for apparatus for paying out an insulation support sheet
First Claim
1. Apparatus for providing a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement, the purlins having a generally vertical portion, the space between the vertical portions of adjacent purlins defining an insulation cavity which is generally rectangular in cross-sectional shape, comprising;
- a. a carriage movable in a first direction along the length of the purlins for paying out a support sheet for support of insulation material as the carriage moves along the length of the purlins so that the support sheet depends from adjacent purlins; and
b. a platform attached to the carriage and extending in a second direction, which is in the opposite direction of the first direction, where the platform is mounted for vertical movement with respect to the carriage to avoid purlin support mechanisms encountered as the carriage moves along the length of the purlins.

Abstract
An apparatus for providing a roof structure of the type has a plurality of purlins spaced apart from one another in a parallel arrangement. The space between the vertical portions of adjacent purlins defines an insulation cavity which is generally rectangular in cross-sectional shape. The apparatus includes a carriage movable in a first direction along the length of the purlins for paying out a support sheet for support of insulation material as the carriage travels along the length of the purlins. The apparatus also includes a platform attached to the carriage and extending in the direction opposite the first direction and placed in the insulation cavity. The platform is mounted on the carriage by two pairs of hinges for vertical movement.

-
a. a carriage movable in a first direction along the length of the purlins for paying out a support sheet for support of insulation material as the carriage moves along the length of the purlins so that the support sheet depends from adjacent purlins; and b. a platform, comprised of a frame and a plate, attached to the carriage and extending in a second direction, which is opposite the first direction, and placed in the insulation cavity, the platform being sufficient for fall protection, and the platform being mounted on the carriage by two pairs of hinges for vertical movement with respect to the carriage, and having a ramp to accommodate purlin support mechanisms encountered as the carriage moves along the length of the purlins. - View Dependent Claims (17)

-
a. a carriage movable in a first direction along the length of the purlins; b. a platform, comprised of a frame and a plate, attached to the carriage and extending in a second direction, which is opposite the first direction, the platform being placed in the insulation cavity and mounted on the carriage by two pairs of hinges for vertical movement with respect to the carriage, and having a ramp to accommodate purlin support mechanisms encountered as the carriage moves along the length of the purlins; and c. a support sheet for support of insulation material, where the support sheet is dispensed from the carriage as the carriage moves along the length of the purlins so that the support sheet depends from adjacent purlins, the support sheet being placed over the platform, and the platform supporting the support sheet inside the insulation cavity. - View Dependent Claims (19, 20)
