Abstract: A pool ladder may have a first and second leg extension, each having a generally continuous profile; a first tread may comprise first and second through-holes, the first through-hole being sized to slidingly receive the generally continuous profile of the first leg extension, and the second through-hole being sized to slidingly receive the generally continuous profile of the second leg extension; and a first and second tread support. The first tread support may be engaged at a tread location on the first leg extension and may be separate from the first leg extension. The second tread support may be engaged at a tread location on the second leg extension and may be separate from the second leg extension. Each of the first and second tread supports may protrude from the respective leg extension a sufficient amount to prevent the first and second through-holes from sliding past the tread locations.

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 combination pool ladder structure, fence and adjustable multi-level deck for an above-ground swimming pool having a wall which extends above the level of the ground including a frame for mounting proximate the external side of the wall, a first ladder pivotally mounted on the frame leading to a lower deck which is below the level of the top of the wall, railings on opposite sides of the lower deck, an upper deck adjustably mounted on the frame above the top of the wall, a second ladder pivotally mounted on the frame proximate the inner surface of the wall, the pivotal mountings of the first and second ladders permitting them to be swung to outwardly extending out-of-the-way positions.

Abstract: An extended-handle lighter including an elongated handle, a socket at one end of the handle for receiving a butane lighter, an actuator mounted at the other end of the handle, and a linkage extending between the actuator and the lighter for selectively causing the lighter to produce a flame. The linkage can either be a flexible cable or a rigid rod.

Abstract: A fastener for entering holes in two adjacent bodies to hold them together and to be completely concealed therein including a flexible resilient tubular body having at least one locating tab centrally located thereon for determining the extent to which spaced portions of the tubular body on opposite sides of the locating tab may enter holes in the adjacent bodies, and resilient flexible locking tabs struck up from the spaced portions of the tubular body for retaining them within the adjacent bodies in which they are located.

Abstract: A lattice consisting of first and second flexible resilient criss-crossed strips each having beveled edges and mating dovetail cutouts oriented in face-to-face relationship with the dovetail cutouts of each of the strips having dovetail sides engaging the beveled edges of the other of the strips. A lattice with criss-crossed strips with one strip having dovetail cutouts with sides which engage mating beveled edges of the other strip. Lattice structures of the foregoing types which utilize hollow strips.

Abstract: A plastic fence having spaced hollow plastic posts with vertically spaced holes in the posts for receiving rails with a friction fit with the rails having vertical rungs, slats, or both which are received between the rails with a friction fit. A plastic gate construction including a frame fabricated from plastic frame sections connected by elbows, vertical rung and slat members extending vertically in the frame, and plastic hinge members formed integrally with the elbows for mating with cooperating hinge elements mounted on sleeves which are secured to a post of a fence.

Abstract: A universal perimeter fence (16) for an above-ground pool. The perimeter fence consists of a plurality of three different assemblies which are fence post assemblies (18), rail assemblies (20) and mounting assemblies which include bottom post connectors (22) and top post connectors (24). The angles of the posts can be varied relative to the pools to accommodate for differing overhangs of top rails (14) and the rail assemblies are field cut the accommodate for differing spacings between the pool wall supports (12) as well as differing angles. Each of the post assemblies (18) include rail connectors (30) which have outwardly extending tubular portions (36), the inner and outer faces (80,76) being at differing angles to provide for differing diameter pools.

Abstract: A ladder consisting of a pair of spaced rails, a plurality of rungs having opposite end portions with first holes extending therethrough for receiving the rails in complementary mating relationship, first slots extending inwardly into the rungs from the bottom sides thereof and terminating at bearing areas which bear on the outer ends of first pins which are carried by the rails, and a pivotal rung-like base having end portions with second holes extending inwardly from the top side thereof for receiving the ends of the rails and second slots extending inwardly into the rung-like base from the top side thereof terminating at bearing surfaces which carry the load transmitted by the outer ends of second pins mounted on the lower ends of the rails.

Abstract: A pool entrance and supporting structure which will both provide an entrance or exit from an above-ground pool and will also provide a support for both a skimmer and a return. The pool entrance and supporting structure (40) includes an entrance structure (42). The entrance structure includes a pair of spaced apart ladders (44, 46) and a platform (48) which extends between upper end portions of the ladders. The pool entrance and supporting structure (40) further includes skimmer support means (50) and return support means (52).By employing the novel pool entrance and supporting structure of this invention improved circulation is achieved within the pool reducing the need for vacuuming, chemicals, and filtering. In addition, the problems encountered with through wall skimmers and returns will be eliminated. Additionally, it will be easier to winterize the pool as the skimmer and return can readily be removed from the pool and stored in an area which will not subject the various components to freezing.

Abstract: A swimming pool construction incorporating solar heating means to heat the pool water to a desired level. The pool includes a surrounding safety fence supported by a plurality of fence supports which are hollow and which include internal passageways. The pool water is passed through the pool support passageways whereupon it absorbs heat from the sidewalls of the fence supports, the surfaces of which have been heated by solar radiation. The fence supports can be made of plastic or other materials, but preferably are dark for improved absorptivity. The pool water can be passed serially through each of the fence supports and suitable thermostat control means can be provided to limit the water temperature increase.
