Abstract: A trailer adapted to be coupled to a tow vehicle and including a frame including a draw bar tube defining a longitudinal axis. The trailer includes a drawbar support pivotally coupled to the draw bar tube and rotatable relative to the drawbar tube about an axis parallel to the longitudinal axis. The drawbar support is biased toward a substantially horizontal orientation. A sliding member is receivable in the drawbar tube and is configured for movement along the longitudinal axis in response to movement of the tow vehicle. A latch member is connected to the sliding member. The latch member is configured to move in response to movement of the sliding member from a first position wherein the drawbar support is retained in a substantially vertical orientation to a second position wherein the draw bar support is free to rotate toward the substantially horizontal orientation.

Abstract: A sound attenuating enclosure for a portable machine includes a lower body having an inner skin and an outer skin spaced apart from the inner skin. The lower body is adapted for having the portable machine mounted therein and also includes one or more wheels rotatably mounted thereto. The enclosure also has an upper body overlying the lower body for containing the portable machine between the upper and lower bodies and a towing element attached to the lower body for pulling the enclosure over a surface. One or more sections of the inner and outer skins are in permanent contact with one another for damping vibrational movement of the skins during operation of the portable machine so as to reduce the level of sound emanating from the enclosure.

Abstract: An enclosure for a portable machine includes a lower body having two or more wheels rotatably mounted thereto, the lower body including an interior region adapted for receiving the portable machine. The enclosure includes an upper body overlying the lower body for enclosing the portable machine within the interior region and a towing element attached to the lower body for pulling the enclosure over a surface, such as a road. The upper and lower bodies substantially comprise polymer materials for minimizing the amount of noise emanating from the enclosure during operation of the portable machine. The lower body may include materials selected from the group consisting of polyethylene and nylon, and the upper body may include acrylonitrile butadiene styrene (ABS). The upper and lower bodies may be formed using a molding process, such as a vacuum molding process.

Abstract: An enclosure for holding a machine includes a lower body made of polymer materials, such as polyolafins and/or nylon. The lower body includes an interior region having a surface with one or more features integrally molded therein and an upper body overlying the lower body for enclosing the machine between the upper and lower bodies. The one or more features integrally molded into the surface of the interior region are adapted for at least partially securing the machine to the lower body. In one embodiment, the one or more features integrally molded into the surface of the lower body include a projection extending above the surface of the interior region and the machine includes a recess formed in a bottom surface thereof. The projection may be sized and shaped to fit within the recess for securing the machine to the surface of the lower body so as to prevent the machine from moving laterally with respect to the surface of the interior region.

Abstract: An enclosure has an outer surface and an inner surface and an opening extending between the outer and inner surfaces. The outer surface of the enclosure includes a curved region surrounding the opening; the curved region having a radius. The enclosure includes a resilient cover which is hingedly secured to the enclosure for selectively covering the opening. The resilient cover moves between a first open position and a second closed position. The resilient cover is molded to normally have a first radius which is greater than the radius of the curved region of the enclosure. When in the first open position, the resilient cover defines an arch having the first radius. When in the second closed position, the resilient cover is compressed and flexes so as to conform to the shape of the curved region of the enclosure. Thus, in the second closed position, the resilient cover defines an arch having a second radius which is smaller than the first radius.
