Abstract: A repositionable downspout extension is formed as an integral blow molded plastic component having three distinct sections. A downspout connector end merges with a corrugated extendible middle section which terminates in a drainage pipe connector. The downspout connector includes two rectangular sections of different sizes defining two different securing segments for engaging two different sizes of downspouts. The middle section is of a pleated configuration and is of variable length by expanding or collapsing of the pleats. The drainage pipe connector is a circular connector for connecting with commonly used corrugated plastic pipe or rigid plastic pipe. In a preferred embodiment the downspout connector end also includes a connector for insertion and retention in the corrugated middle section.

Abstract: A plastic fence section comprises a series of connected hollow chambers with at least upper and lower horizontal chambers extending the length of the fence section for receiving reinforcing members. The fence section is made of plastic material. The hollow chambers are separated by pinch off regions. The fence section provides a visual block and has a similar appearance on either side of the fence section. The fence section has a post edge and a panel joining edge. The panel joining edge is adapted to engage and overlap with a second fence panel section.

Abstract: An orthopaedic support comprises a substrate having a series of channels in one surface thereof with a series of vent holes in the channels to promote heat dissipation through the substrate. The channels provide cooling of the skin in contact with the orthopaedic support without rendering the substrate prone to damage. Vent holes are located in the channels to provide venting through the orthopaedic support and the dissipation of heat.

Abstract: The railing section includes an integral component defining an upper rail, a lower rail and a series of spindles or balusters or other screening or blocking structure therebetween which forms a structural connection between said rails. These components are interconnected by hollow cavities which can receive a reinforcing material. The railing section is preferrably made by blow molding and the upper and lower rails can receive structural members interior to the rails to improve the strength of the railing section.

Abstract: A picket fence section is made as a single integral plastic component. The fence section can be made in various length including a length appropriate for securement between posts spaced at eight foot centers. The picket fence section is preferrably of a high density polyethylene material and made by blow molding.

Abstract: A railing system suitable for decks, stairs, porches and other structures uses a collar connector applied over the open end of a tabular rail for securing the rail to a support surface. The connector has an exterior collar into which the open end of a railing is inserted. The railing is also engaged on the interior of the railing by an inserted plug. The railing is trapped between the inserted plug and the collar whereby a tight connection is achieved. The gap between the inserted plug and the exterior collar narrows from the open end of the collar towards the base.

Abstract: A support post for a railing system comprises a base plate adapted to engage and support a vinyl support post at the base thereof and an interior support column located interior to the vinyl post. The support column is coupled to the base plate to form a high strength connection therewith. The upper end of the support column includes an arrangement for vertical adjustment of the vinyl support post.

Abstract: A direct vent gas fireplace is provided with a heat shield forming a combustion air expansion and distribution chamber covering a substantial portion of the upper surface of the firebox enclosure and having a circular combustion air inlet opening in its upper surface and being in communication with the lower portion of the firebox, and the products of combustion from the firebox are directed out of the fireplace through a pipe extending through the upper enclosure surface and out through the combustion air inlet opening in the heat shield with the axis of the pipe being offset from the center of the inlet opening so that when a combustion air inlet duct is sleeved over the pipe and connected to the inlet opening a portion of the combustion air path between the pipe and duct which feeds into the combustion air expansion and distribution chamber is substantially widened to provide space for the combustion air to expand outwardly rather than backing up the combustion air duct.

Abstract: An eavestrough system utilizes a two-piece hook wherein a small clip is positioned and secured on a fascia and thereafter assembled eavestroughing and eavestrough hooks are conveniently attached thereto, preferably by means of a sliding snap fit relationship. The eavestrough hooks are slidable on the eavestrough section and can be preassembled on the eavestrough at ground level. This, in combination with the fast engagement with the clips, simplifies installation. The invention is also directed to an improved eavestrough hanger having resilient spring arms.

Abstract: A termination device for a through the wall connection to the double walled coaxial ducting of a horizontal direct vented gas fireplace or the like comprising a mounting means having an opening therethrough for mounting said device on the exterior of a wall having a passage therethrough with the opening registering with the passage, a first pipe adapted for connection with the outer of the coaxial ducts secured to the mounting means and projecting inwardly thereof and adapted to extend through the wall passage, deflector means supported in spaced relation outwardly from the mouth of the first pipe and presenting an air deflecting surface formation surrounding and sloping inwardly towards the mouth of the first pipe to a central opening in substantially coaxial relation with but spaced from the first pipe, said air deflecting surface formation being adapted to deflect air inwardly into the first pipe, a second pipe adapted for connection with the inner of the coaxial ducts extending from an outer end located o

Abstract: A corrosion resistant insert of the present invention is used for fitting at an opening in a metallic liquid tank. The insert has an open end, a radially outwardly extending lip at the open end, a closed end and an axially extending side wall spacing the open end and closed ends from one another. The closed end has a displaceable portion secured to the insert in a preweakened manner which facilitates opening in one direction while resisting opening in the other direction. The use of the insert in the tank enables lining and then pressure testing of the tank ready for fittings after which the closed end of the insert is opened to allow liquid flow through the tank when the tank is in use.

Abstract: The method of the present invention is for foam insulating a water heater where the water heater has an outer shell and an inner tank with tank fittings, the outer shell having tank fitting openings and the inner tank and outer shell being separated by an insulation space. The method comprises locating foam flow barriers between the inner tank and the outer shell around the periphery of each of the tank fitting openings and then spraying foam forming material into the insulation space with the foam barriers preventing the foam from escaping outwardly through the tank fitting openings.
