The present invention relates generally to swimming pools and, more particularly, to a sealing closure for closing a skimmer opening to prevent water from entering the skimmer when the swimming pool is closed for the season.
It is common to employ one or more skimming devices in the sidewalls of swimming pools, hot tubs, and the like to permit surface water to be drawn off by a pump, to be filtered at a remote location and then optionally heated, and returned to the pool through one or more return ports. While the present disclosure focuses on skimming devices for swimming pools, it is to be understood that various other water structures, including, without limitation, hot tubs, spas, jet tubs, and the like can have similar or identical skimming devices. These skimming devices have a skimmer opening in a side wall of the pool for drawing the surface water to the pump. During normal use of the pool, the surface level of the water in the pool is at the same level as the skimmer opening such that water from the surface can enter the skimmer opening. When the pool is closed, for example during the winter season, it is sometimes desirable to maintain a lower level of water in the pool for structural purposes. Even if completely drained, the water level in the pool will naturally rise during the closed season due to rainwater and melting snow, such that the water level oftentimes rises to a level of the skimmer opening or above. In such cases, it is necessary to close off the skimmer opening to prevent backflow of water through the skimmer opening and the conduits that connect the skimmer opening to the filter, pump equipment, and heater so as to prevent damage to these components due to freezing.
Within the prior art, one way of closing the skimmer opening is to employ an elongated, plug-like element. The plug element is threadably secured within the floor of the skimmer body to seal the conduit communicating with the pump and filtration equipment. In other embodiments, a detachable cover plate or panel is removably attachable to the skimmer opening. Some of these existing devices either require a retrofit of the skimmer faceplate in order to make sealing contact with a closure member. Other known devices require the use of a polymeric flexible sealing member which snaps over the skimmer opening. Such faceplate seals may lose their effectiveness due to weathering of the polymeric material, and also may require special retrofitting of the skimmer opening member to provide better sealing between the skimmer and the flexible snap-on faceplate. In addition, the existing faceplate seals may crack or be otherwise compromised due to temperature-related shirking and/or contact with ice. Furthermore, due to the conventional square or rectangular shape of the skimmer opening, the existing devices for closing the skimmer opening may not provide an adequate seal in the corners of such skimmer openings. Accordingly, there is a need in the art for an improved sealing closure for the skimmer opening that overcomes the deficiencies of the prior art.
In view of the existing need in the art, it would be desirable to develop a sealing closure assembly for a swimming pool skimmer opening that overcomes the deficiencies associated with the existing devices.
In accordance with some preferred and non-limiting embodiments or aspects of the present disclosure, a sealing closure assembly for closing a skimmer opening of a swimming pool may include a closure faceplate and a cover. The closure faceplate may include a sidewall with a central opening shaped to correspond to the skimmer opening, and a flange protruding from the sidewall to overlap a peripheral area of the skimmer opening.

Having described the structure of the sealing closure assembly 100, a method of installing the sealing closure assembly 100 to close the skimmer opening 101 and prevent the passage of water into the skimmer opening 101 will now be described. To install the sealing closure assembly 100, the closure faceplate 102 is first installed on the skimmer opening 101, for example by snapping the closure faceplate 102 such that the one or more locking elements 110 lockingly engage the closure faceplate 102 with the skimmer peripheral flange 107. In various other aspects, the closure faceplate 102 may be installed on the skimmer peripheral flange 107 by one or more fasteners, adhesive, or any other mechanical connection means that securely retains the closure faceplate 102 on the skimmer peripheral flange 107. When installed, the closure faceplate 102 surrounds the skimmer opening 101 such that obstructing the central opening 108 of the closure faceplate 102 also obstructs the skimmer opening 101.
Next, the cover 104 is connected to the closure faceplate 102 such that the second ends 136 of the one or more closure members 130 on the cover 104 extend into the central opening 108 of the closure faceplate 102. During installation of the cover 104 onto the closure faceplate 102, the distal edges 139b of each of the locking members 138 contacts the flange 103 of the closure faceplate 102 such that the second end 136 of the closure members 130 is deflected from an initial position to a deflected position. With continued movement of the cover 104 toward the closure faceplate 102, the distal edges 139b of each of the closure members 130 pass over the flange 103 of the closure faceplate 102 such that the closure faceplate 102 is captured between the proximal edge 139a and the inner surface of the cover plate 112 (see
