Abstract: A housing system for a calf including a housing unit having a first exterior sidewall, a second exterior sidewall, a front exterior wall extending between the first exterior sidewall and the second exterior sidewall, a roof extending between the first exterior sidewall and the second exterior sidewall, an opening at least partially defined by the front exterior wall for ingress and egress of a calf into and out of the housing unit, and an enclosed living space extending between and bounded by the first and second exterior sidewalls and the front exterior wall.

Abstract: A generally hollow plastic molded pen front provides multiple operating positions of the door having sets of interdigitating hinge knuckles on the door and door jamb on both the left and right side. The door also may be swung in or out, and one or more stops can be provided for any of four configurations—left hinged swing in; left hinged swing out; right hinged swing in; right hinged swing out. With the stops removed, the door may be swung both in and out. In one embodiment a J-shaped latching rod secures both the upper and lower portions of the door when latched and a J-shaped hinge rod cooperates on the other side and can use some of the same holes as the latching rod. In another embodiment, a pivoting handle works to secure the door in a catch channel for all six configurations. Other integrated features provide a choice of feed opening sizes and a guard that minimizes feed and water contamination.

Abstract: An animal housing unit has an enclosed monolithic hutch with an open front and a separate open top pen attached to the front of the hutch whereby an animal will be contained in the unit by the combination of the hutch and pen. The pen has a sliding roof that can be extended over the pen, with an extension that shields a feed bucket location from rain. The units can be supported on a composite steel and plastic base and drain through floor tiles can be used on the base, which can be supported on adjustable supports to support the base above or close to the ground. The roof is bi-laterally curved or partially spherical to promote shedding of rainwater, and gutters are molded into the hutch to channel rain away from the interior living space. Roof guiding and securement mechanisms are molded into the hutch and sliding roof. The sliding roof is double walled for insulation and strength and extruded members sandwich the lower edges of the hutch.

Abstract: A free-standing plastic livestock confinement system includes hollow plastic panels assembled together to provide interconnected walls that create confinement areas. One of the walls provides a door opening and a door that can be closed across the opening. The door is a hollow plastic panel with an opening for an animal to place its head through for access to food. The door is molded with a bucket holder and the opening in the door over the bucket holder. The bucket holder is recessed such that a bucket received in the bucket holder will extend partially into the confinement area.

Abstract: An indoor livestock confinement system includes a plurality of hollow plastic panels. One of the hollow plastic panels defines a U-shaped door frame. The door frame is open at the top and includes an attachment for a door at one edge. The door frame includes a reinforcement inside the panel that extends across a bottom threshold and sides of the door frame.

Abstract: A wall panel for a livestock confinement pen made of a hollow plastic twin sheet thermoformed body with a grid divider received in an opening of the body between the two sides of the body. One side has flanges by the opening to receive a cover cut from the other side over the opening.

Abstract: Thermoplastic parts are made of predominantly single unit thickness but with marginal areas of increased thickness by molding two parts in a common mold having overlapping mold portions. Two thicknesses of thermoplastic material are molded together in the areas of increased thickness at opposite ends of the common mold and the parts are separated from one another by trimming such that each part has an area of increased solid wall thickness and an area of reduced thickness.

Abstract: The invention provides an indoor livestock confinement system that includes a plurality of hollow plastic panels. Each panel includes a plurality of spaced tabs at its ends. A first end of each panel includes a first set of tabs, and a second end of each panel includes a second set of tabs. Each set of tabs includes at least one tab at a top portion of the end, at least one tab at an intermediate portion of the end, and at least one tab at a lower portion of the end. The tabs of the first set are offset vertically from the tabs of the second set such that the first set of tabs of a first panel fit vertically between the second tabs of another panel when the ends of the panels are put together. Each tab includes a hole such that a rod can be inserted down through the tabs to lock the panels together. The livestock confinement system may include additional features, such as ventilation components, reinforced panels, and bucket holders.

Abstract: A cab for a vehicle, such as an all terrain vehicle, a tractor, or small construction vehicle, is constructed of twin-sheet thermo-plastic panels that can be easily assembled, preferably with snap-together interlocking features. One of the panels can be a door panel having a door hinged to a door frame to control passage through a doorway. Both the door and the door frame have spaced apart hinge knuckles that interleave along a hinge axis to allow the door to pivot about a hinge pin. The door and door frame can be molded in a single twin-sheet panel. The two walls of the panel are fused together along the outer periphery of the panel door portion and the inner periphery of the panel door frame portion. The door is separated from the door frame by cutting the each of the walls along a door perimeter between the door and door frame portions of the molded panel.

Abstract: A molded plastic skid base for a resin building is formed with all of its openings facing downward and with runners integral with a deck that forms a floor of the base. Replaceable wear plates cover the bottoms of the runners and have truck loading notches molded at their ends and a longitudinal channel in which fastener heads are positioned. Stake down slots are provided in the ends of the runners and wear plates in a diagonal orientation so as to be aligned toward the center of the building, below the base. The floor of the base is a grid formed of diagonally oriented ribs, at least some of which may be shorter in their center than at their ends, is crowned in the center and has openings which taper upwardly. A solid sheet may be placed over the grid to close it.
