Abstract
A swimming pool which has a plastic liner sheet having an inner surface directed toward the interior of the pool to define the interior thereof and an outer surface directed away from the interior of the pool. A plastic backing structure which is rigid engages the outer surface of the liner sheet so as to form a backing for the latter. The plastic backing structure takes the form of a plurality of units situated one next to the other along the periphery of the pool with each of these units being composed of a series of extrusions situated one next to the other. Each of the extrusions is hollow and has front and rear parallel walls interconnected by strips which are situated one above the other between these walls.
Claims38
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, and concrete-retaining means operatively connected with an upper region of said plastic backing means and being composed of a plastic sheet material which extends from said upper region of said plastic backing means first upwardly and inwardly and then rearwardly and outwardly where said concrete-retaining means has an upper wall which is inclined slightly downwardly as well as rearwardly with said concrete-retaining means forming a hollow space capable of receiving concrete, and said concrete-retaining means having at the region where it extends upwardly and inwardly from said plastic backing means a wall structure integral with the concrete-retaining means and defining a groove for receiving an upper edge region of said plastic liner sheet.
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, and substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, said plastic backing means including a plurality of units arranged one next to the other along the periphery of the pool, each of said units including a plurality of extrusions situated one above the other and connected one to the next, each extrusion being hollow and having an inner wall engaging said outer surface of said liner sheet and an outer wall spaced from and parallel to said inner wall, and each extrusion including a plurality of connecting strips situated one above the other between said inner and outer walls and being integral therewith, said inner and outer walls of each extrusion terminating at their lower ends in inwardly directed flanges which are spaced from each other, one of said strips forming an upper end strip of each extrusion and extending between and being connected to upper edges of said inner and outer walls of each extrusion, and said upper end strip of each extrusion having an upper surface fixed with a springy connecting means for connecting each extrusion of each unit to the inwardly directed flanges of the next upper extrusion.
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, and substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, said plastic backing means including a plurality of units arranged one next to the other along the periphery of the pool, each unit having an upper end carrying an upper connecting means for connecting an upper edge region of the liner sheet fluid-tightly to each unit, each upper connecting means of each unit including a hollow upper extrusion having an inner wall engaging the outer surface of said liner sheet and an outer wall directed away from said sheet, said extrusion having an upper wall extending between said inner and outer walls and defining between said inner and outer walls a longitudinal groove for receiving an edge region of the liner sheet with the latter extending from said groove forwardly along said upper wall between said groove and inner wall of said extrusion and then downwardly along said inner wall, said upper connecting means including a cover seated on said upper extrusion and having a tongue extending into said groove and wedged against said edge region of said liner sheet for holding the latter in said groove, said upper extrusion having at said groove a pair of opposed wall portions having inwardly directed side surfaces provided with beads of yieldable compressible plastic soften than the remainder of the upper extrusion, said sheet having a relatively thick edge region received in said groove and said tongue pressing against the beads at one side surface of said groove and pressing said edge region against the beads at the other side surface of said groove for deforming and compressing said beads to provide the fluid-tight connection which prevents water of the pool from becoming located between said sheet and backing means.
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, and substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, said plastic backing means including a plurality of units arranged one next to the other along the periphery of the pool, each unit having an upper end carrying a connecting means for connecting an upper edge region of the liner sheet fluidtightly to each unit, said connecting means forming part of an extrusion which includes a gutter situated outwardly of and being integral with said connecting means and into which water from the pool can overflow.
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, and substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, said plastic backing means including a plurality of units arranged one next to the other along the periphery of the pool, a plurality of channel units being situated between and receiving said units of said backing means for interconnecting the latter units, each unit of said backing means having an upper end region carrying a connecting means for connecting an upper edge region of the liner sheet fluid-tightly to each unit of said backing means, said connecting means being integral with a gutter surrounding and situated outwardly of all of said units and a concrete retainer unit connected with said gutter at an outer upper region thereof, and all of said units as well as said gutter and connecting means being made of plastic extrusions.
In a swimming pool, a plastic liner sheet having an inner surface defining the interior of the pool and an outer surface directed away from the interior of the pool, and substantially rigid plastic backing means engaging said sheet at the outer surface thereof and forming a backing for said sheet, said plastic backing means including a plurality of units arranged one next to the other along the periphery of the pool, a concrete-retaining means being operatively connected with an upper region of each of said units for retaining a concrete deck surrounding the pool, said concrete retaining means having an inner wall provided with an inner surface directed toward the interior of the pool, and an extension of L-shaped cross section integrally formed with the latter wall and defining with said wall an upwardly directed groove for receiving a top edge of the liner sheet.
