Abstract: The mechanically assisted horizontal trellis system is a device intended to help support plant weight and facilitate more simplistic methods for erection and removal of a horizontal trellising system. In other words, the device can easily extend and retract to form a grid system to support a variety of plant heights and sizes. In order to accomplish this the device includes a plurality of legs that are designed to hold a grid frame above or next to the plants growing in a variety of ways. Further, the plurality of frame tubes is equipped with retractable devices that allow the user to easily assemble and disassemble the grid system. More specifically, the device includes retractable cable and fastener system that may be easily and efficiently assembled and disassembled to create the grid system to support plants and flowers without damaging or disturbing the plants or flowers.

Abstract: An apparatus for ventilating a room comprises an outer casing having an open bottom and having a central axis extending therethrough and a fan coaxially supported within the outer casing along the central axis, the fan having a plurality of fan blades extending radially from the central axis. The apparatus further comprises an air opening extending into the outer casing around the fan and a ring surrounding the fan and separating the fan from the air opening and defining an air passage from the air opening to the fan.
