Abstract: A trailer and platform unit of the type having a trailer defining a rear-end opening from the ground up through which an enclosure is accessed, with the platform adapted to support material and being loaded onto the trailer through the rear-end opening by the trailer backing into the platform whereby the platform engages and is supported by rails on opposed sides of the enclosure. The platform comprises a support surface to support material and lateral edge surfaces defining a periphery of the platform. Stabilizer devices each have a support arm with a first end connected to the platform, a second end projecting laterally away from one of the lateral edge surfaces of the platform, a base plate at the second end of the support arm. Adjustment mechanisms for each stabilizer device sets the vertical position of the base plate with respect to the platform so as to increase the footing of the platform on the ground.

Abstract: An anchor assembly for hollow walls comprises an anchor body and a toggle member moveably mounted to the anchor body. The toggle member is displaceable between first and second positions thereof, wherein in the first position the toggle member is substantially aligned with the anchor body such that the anchor assembly can be rotated for insertion in the wall, and wherein in the second position the toggle member extends behind the wall at an angle relative to the anchor body with the anchor body extending through the hole in the wall. The toggle member is held captive in the first position but is displaceable longitudinally along the anchor body when an appropriate fastener is introduced in the anchor body. A deflector is provided for causing, after a sufficient longitudinal displacement of the toggle member has released the same from a captive state thereof, the toggle member to pivot relative to the anchor body to the second position.

Abstract: A removable seats system includes a number of vertically movable platforms supported by a platform support and displacement device which engages the platforms and which positions the platforms in a horizontally successively spaced configuration defining a gap between each two successive platforms having selective independent vertical displacement of the platforms. The removable seats system further includes a number of seat elements each associated with a corresponding platform and each including: a row of seats including at least one seat; and a seat supporting structure carried by a platform and supporting the row of seats. Each one of the seat members is movable relative to its corresponding platform between an operative position in which the row of seats is located above its corresponding platform, and a concealed position in which the row of seats is located under a platform.
