Porthole assembly for a swimming-pool wall

Claim 2

A porthole assembly for mounting in registry with an opening in a swimming-pool wall having an inner and outer face, said porthole preventing water in the swimming-pool from passing through said opening, and said porthole assembly comprising: a lamp unit holding means mounted against said outer face peripherally of said opening; a continuous transparent cover means mounted against said inner face and completely spanning said opening so that water from the swimming-pool cannot pass therethrough; means for securing said cover means and said holding means to said wall, the securing means having a tool-engaging end accessible from outside said swimming-pool; means on said cover means for receiving the opposite end of said securing means in a watertight arrangement so as to avoid contact between said securing means and water in said swimming-pool; and a lamp unit removably mounted to said holding means, said lamp unit being separate and distinct from said transparent cover means.

Claim 3

A porthole assembly as defined in claim 1, wherein said cover means is a transparent plate having a plurality of circumferentially-spaced holes each receiving one of said securing means therethrough; said means for receiving the opposite end of said securing means defining a plurality of enclosed housings mounted to the outer face of said plate for contact with water in the swimming-pool, said housings being in registry with said holes, and said housings providing continuity of said transparent cover means so that water from said swimming-pool may not pass therethrough.

Claim 4

A porthole assembly as defined in claim 2, wherein said housings are integrally formed of said cover.

Claim 5

A porthole assembly as defined in claim 2 or 3, wherein said plate and said housings are made of polycarbonate.

Claim 6

A porthole assembly as defined in claim 1, further comprising water sealing means provided in a circumferential and peripheral area defined by the periphery of said swimming-pool wall, said securing means and the periphery of said cover means.

Claim 7

A porthole assembly as defined in claim 2, wherein said holding means consists of a cylindrical body having a longitudinal flange perpendicular to said wall and an inner flange integrally formed at one end of said longitudinal flange and extending parallel to said swimming-pool wall; said inner flange having holes in registry with said holes of said plate to receive said securing means therethrough; means on said longitudinal flange for engagedly receiving cooperating means on said lamp unit for mounting said lamp unit to said holding means.

Claim 8

A porthole assembly as defined in claim 6, wherein said means on said longitudinal flange being so disposed therein as to mount said lamp unit at an angle relative to an axis normal to said swimming-pool wall whereby light emitted from said lamp unit is directed towards the bottom of said swimming-pool.

Claim 9

A porthole assembly as defined in claim 7, wherein said means on said longitudinal flange are L-shaped grooves and wherein said cooperating means on said lamp units are studs received in said L-shaped grooves.

Claim 10

A porthole assembly as defined in claim 6, further comprising ventilation openings on said lamp unit and on said longitudinal flange of said holding means.

Claim 11

A porthole assembly adapted to be mounted in registry with an opening in a swimming-pool wall having an inner and outer face comprising: a lamp unit holding means mounted to said outer face peripherally of said opening; transparent cover means mounted to said inner face over said opening; means for securing said cover means and said holding means to said wall, said securing means having a tool-engaging end accessible from outside said swimming-pool; means on said cover means for receiving the opposite end of said securing means in a watertight arrangement so as to avoid contact between said securing means and water in said swimming-pool; a lamp unit removably mounted to said holding means; said cover means comprising a transparent plate having a plurality of circumferentially-spaced holes each receiving one of said securing means therethrough; said means for receiving the opposite end of said securing means defining a plurality of enclosed housings mounted to the outer face of said plate and in registry with said holes; said holding means comprising a cylindrical body having a longitudinal flange perpendicular to said wall and an inner flange integrally formed at one end of said longitudinal flange and extending parallel to said swimming-pool wall; said inner flange having holes in registry with said holes of said plate to receive said securing means therethrough; means on said longitudinal flange for engagedly receiving cooperating means on said lamp unit for mounting said lamp unit to said holding means; and ventilation openings on said lamp unit and on said longitudinal flange of said holding means.

Claim 12

A porthole assembly adapted to be mounted in registry with an opening in a swimming-pool wall having an inner and outer face comprising: a lamp unit holding means mounted to said outer face peripherally of said opening; transparent cover means mounted to said inner face over said opening; means for securing said cover means and said holding means to said wall, said securing means having a tool-engaging end accessible from outside said swimming-pool; means on said cover means for receiving the opposite end of said securing means in a watertight arrangement so as to avoid contact between said securing means and water in said swimming-pool; a lamp unit removably mounted to said holding means; said cover means comprising a transparent plate having a plurality of circumferentially-spaced holes each receiving one of said securing means therethrough; said means for receiving the opposite end of said securing means defining a plurality of enclosed housings mounted to the outer face of said plate and in registry with said holes; said holding means comprising a cylindrical body having a longitudinal flange perpendicular to said wall and an inner flange integrally formed at one end of said longitudinal flange and extending parallel to said swimming-pool wall; said inner flange having holes in registry with said holes of said plate to receive said securing means therethrough; means on said longitudinal flange for engagedly receiving cooperating means on said lamp unit for mounting said lamp unit to said holding means; and ventilation openings on said lamp unit and on said longitudinal flange of said holding means.
