Elder, 241 Iosco Beach, East Tawas, Mich. 48730 Fiied Nov. 5, 1965, Ser. No. 506,509 2 Claims. (Cl. 160206) The present invention relates to swimming pool enclosures and more particularly to an improved retractable and extendable cover for a swimming pool.
An object of the invention is to provide improved means for enclosing a swimimng pool.
Another object is to provide improved retractable means for covering a swimimng pool.
Another object of the invention is to provide in a retractable swimming pool cover of the hinged panel type means for maintaining said cover in an accordion arrangement.
A further object of the invention is to provide means for positioning the lower hinged joints of the sections of a folding, accordion type, hinged panel cover at equally spaced stations when said roof is extended.
Still a further object of the invention is to provide means for supporting the upper hinged joints of the sections of a folding accordion type, hinged panel cover.
Broadly, the invention includes a building surrounding a swimmng pool and having a rectangular aperture in the roof directly over and substantially the same size as the pool. A retractable cover of the hinged panel type is provided for the aperture and consists of two opposing hinged arrays of panels adapted to be respectively extended longitudinally from each end of the aperture to meet at the transverse centerline of the aperture to cover the pool, and to be partially or completely withdrawn toward the respective ends of the aperture to expose the pool to the sun and other elements when desired. Each of the two arrays includes a plurality of transverse waterproof panels, each hingeably joined to each adjacent panel in accordion arrangement, providing alternate ridges and valleys, and disposed to expand when extended and to contract compactly when retracted. Novel means are provided for positioning each inverted, V-shaped section of the arrays at its respective station when the arrays are extended, to provide additional strength and support for loads of rain, snow, and ice deposited thereon while the pool is covered.
The above and other objects of the invention which will later become apparent as the following description proceeds, are obtained by the present invention, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings, forming a part of the specification in which like characters are employed to designate like parts throughout the same, and wherein:
FIGURE 1 is a perspective view of a swimming pool enclosure embodying my invention.
FIGURE 2 is a side elevation of a portion of a swimming pool enclosure embodying my invention.
FIGURE 3 is a plan view of a swimming pool enclosure with the roof removed.
FIGURE 4 is a side elevation of the hinged panel cover of my invention when completely extended.
FIGURE 5 is a side elevation of the hinged panel cover of my invention when completely retracted.
FIGURE 6 is a plan view of the roof aperture, supporting structure for the hinged panel cover, and means for positioning the lower hinged portion of the cover sections at regular stations when extended.
FIGURE 7 is a side elevation of the upper hinged join of a section of the hinged panel cover of my invention FIGURE 8 is a side elevation of the lower hinged join of a section of the hinged panel cover of my invention.
FIGURE 9 is an end view of a portion of a section 0; the hinged panel cover of my invention.
FIGURE 10 is a plan view of the hinged panel cover 01 my invention in extended position and showing mean: for retracting and extending same.
Referring now more particularly to the drawings, I provide a rectangular building generally indicated ,at 10 and surrounding a conventional swimming pool 12 and colored, plastic covered benches 14. The sides of building 10 include a lower tier of panels 16, preferably formed 01 colored Masonite orasbestos, with adjustable aluminum louvres 18 therein, an upper tier of similar panels 20, and combination aluminum screens and sliding glass windows 22, preferably of the Thermopane type, -or conventional folding doors, powered or manually operated, supported therebetween. A plurality of aluminum and glass doors 34 provide entrance to the building, and an adjustable, aluminm, louvred port 26 for an exhaust fan is mounted above each door.
The roof structure of building 10 includes an inclined, overhanging apron portion 28 surrounding a rectangular aperture 29 directly over substantially the same width, and slightly longer than pool 12. A pair of upstanding sidewalls 30, 30 and a pair of gable end walls 32, 32 preferably formed of colored Masonite hardboard, surround aperture 29 and support a pair of relatively narrow shingled roofs 34, 34 which respectively cover a pair of enclosures 36, 36 which extend over the ends of aperture 29 and provide storage of the hinged panel cover assembly of my invention as more particularly hereinafter described.
I provide in my invention a novel hinged panel cover generally indicated at 38 which consists of two identical arrays 44 40 arranged to be extended from enclosures 36, 36, respectively, to meet at the transverse centerline of aperture 29 to cover the pool, and to be partially or completely withdrawn toward the ends of the aperture to uncover the pool when desired. Each array includes a plurality of identical, elongated, waterproof, transverse cover panels 42, preferably formed of fiberglass or similar weatherproof material which permits the passage of sunlight therethrough, and arranged in accordion fashion, providing alternate ridges and valleys. A transverse piano hinge 44 hingeably joins the upper ends of each contiguous pair of panels 42, 42 which form what is hereinafter termed a section. A transverse rubber boot 46 extends the entire length of the upper joint formed by hinge 44 and is fastened to the contiguous panels 42, 42 by a clip 48, screws 50, and waterproof cement (not shown) or the like. A similar transverse piano hinge 52, hingeably joins the lower ends of each contiguous pair of cover panels 42, 42 and the lower joint thereby formed is protected by a similar rubber boot 54 which is fastened to the panels by similar clips 56 and screws 58 in a similar manner.
A pair of rotatable grooved wheels 60 are mounted coaxially with the hinge axis of upper hinge 44 and upon two pivotally joined hinge plates 62, 62 fastened by screws 64 or the like to each end of panels 42, 42, respectively. Each wheel 60 is engaged by and supported upon a longitudinal cable 66 connected at its ends to a pair of tension springs 68, 68 which are anchored to end walls 32,
Another pair of rotatable grooved wheels 66 are mounted coaxially with the hinge axis of lower hinge 52 upon two similar pivotally joined hinge plates 68, 68, fastened ered and exposed to the plates 78 and cables 80,
by screws 69 or the like to each end of roof panels 42, 42, and are arranged to engage and ride respectively upon a pair of inverted, V-shaped tracks 70 supported upon a pair of longitudinal girders 72 which extend the length of aperture 29 and below sidewall 30, as best shown in FIGURE 9. A second cable 74 extends longitudinally above each track 70, is anchored to end walls 32, 32, and engages the upper portion of wheels 66 to retain the wheels in contact with the track and to hold down the cover in the event of Windstorm. A rubber end boot 76 is fastened to each end of each panel 42 to slidingly seal the space between the panel and the proximate sidewall 30 against the elements.
Another novel feature of my invention resides in the provision of a plurality of stop members 78 to position each inverted, V-shaped section of the cover assembly at its respective station when the cover assembly is extended. Stop members 78 are formed of metal plates fastened securely to side wall 30 and extend inward to engage panels 42. Stops 78 are graduated in length, from a maximum length near the transverse centerline of the pool to a shorter length near the ends of aperture 29, and panels 42 are formed to have complementary differential lengths so that the lead panel of each pair of panels forming an inverted, V-shaped section will contact only that stop 78 which halts its forward movement at the proper position when the cover is extended. Thus the forwardmost panel 42 of each of the two opposing arrays 40, 40 of panels will contact only that stop 47 which lies near the transverse centerline of the enclosure and extends furthest from sidewall 30, and will clear all intermediate stops; the lead panel of the next panel section will contact and its forward motion be halted by the next stop in the roof 34, will engage only one of the next pair endward series of stops, and so on, so that each section of panels will be halted and maintained at the same, single position each time cover 38 is extended. When the two arrays 40, 40 of panels are withdrawn toward enclosures 36, respectively, each stop 78 permits all panels 42 forwardly of it to clear 7 it during their rearward movement.
As best shown in FIGURE 10, the opposite arrays 40, 40 of the cover 38 are caused to be extended and retracted by cables 80 and pulleys 82, arranged in conventional manner to cause both arrays of panels 42 simultaneously to traverse aperture 29 longitudinally in mutually opposite directions, and coiling drums 84 arranged to be rotated by shaft 86'journaled at their extreme ends upon journals 88 and supported at their other ends by speed reducers and gear boxes 90 which, in turn, are powered by a pair of synchronized reversible electric motors 92. Conventional electrical power and control means, including electrical switches and limit switches (not shown), are provided to enable the operator to extend and retract the roof assembly.
In operation, when the cover 38 is in an open position, if the operator wishes to extend and close the cover he actuates electrical motor 92 in one direction thereby causing arrays 40, 49 to be drawn toward the transverse centerline of aperture 29, and covering the aperture, as best shown in FIGURE 4. Each stop 78 then contacts the lead panel 42 of each panel section at the proper position and maintains it against further forward movement. The swimming pool is then completely covered and enclosed when it is desired to retract and open cover 38, the operator actuates motor 92 in the opposite direction, thereby causing arrays 40, 40 to be drawn toward and folded come pactly into enclosures 36 and opening aperture 29, as best shown in FIGURE 4. The swimming pool is then uncovsunlight and otherelements from above.
It will be particularly supported in inverted,
noted that each hinged section is V-shaped configuration by stop thereby providing strength to support loads of rain, snow and ice when the pool is covered while permitting panels 42 to be formed of material of light weight and hence to be easily traversed. It will also be noted that spring-loaded cable 66 yieldingly urges each panel 42 toward an upright position, thus preventing collapse of the sections during traverse or storage.
The improved enclosure of my invention surrounds and protects the pool against the elements and the entrance of dirt, rodents, and other foreign matter, thus reducing the cost of filtering, cleaning and vacuuming the pool. Further, it prevents entry of unauthorized persons except through the locked door, and accidentatl drownings of such persons are eliminated. Still further, heat' loss from the pool by dissipation during winter or the cool hours of night is reduced by reason of the complete enclosure of the pool. In the case of a heated pool, and with thermostatic control, the expense of maintaining the water at the desired temperature is thus reduced.
It is to be understood that the 'form of the invention herewith shown and described is to be taken as a preferred embodiment of the same'and that resort may be had to various changes in construction without departing from the scope of the su'bjoined claims.
