The recess covers include a flexible sheet adapted to at least partially cover the recess, and one or more fasteners mounted to an edge of the sheet. The fasteners are adapted to engage a main pool cover. The fastener may be an elongated fastener having a receptacle adapted to receive a projection mounted on the main pool cover. The receptacle may have an opening defined by opposing arms adapted to deflect when contacted by the projection on the main cover. The flexible arms may also include projections that enhance engagement of the receptacle with the projection on the main pool cover. Swimming pool peripheral recess cover fasteners are also provided. ## Claims ### Claim 1 A swimming pool peripheral recess cover fastener adapted for use with a peripheral recess having a width, the width extending from a first end of the peripheral recess to a second end, opposite the first end, the fastener comprising: an elongated receptacle, the elongated receptacle extending across the width of the peripheral recess and having an elongated opening defined by opposing elongated flexible arms and an internal cavity in communication with the opening, the internal cavity adapted to receive and retain a mating projection mounted on a main pool cover; and an elongated flange extending from the elongated receptacle opposite the elongated opening, the elongated flange adapted to be mounted to a peripheral recess cover. ### Claim 2 (depends on 1) The fastener as recited in claim 1, wherein the opposing elongated flexible arms comprise arms, each of the arms having a free end adapted to deflect when contacted by the mating projection. ### Claim 3 (depends on 2) The fastener as recited in claim 2, wherein each of the opposing arms further comprises a projection adapted to engage the mating projection. ### Claim 4 (depends on 1) The fastener as recited in claim 1, wherein the internal cavity comprises an internal surface having at least one rib adapted to contact the mating projection and minimize rotation of the mating projection. ### Claim 5 (depends on 1) The fastener as recited in claim 1, wherein the fastener comprises an elastomeric fastener. ### Claim 6 (depends on 1) The fastener as recited in claim 1, wherein the peripheral recess comprises a stair assembly. ### Claim 7 (depends on 1) The fastener as recited in claim 1, wherein the elongated receptacle comprises an elongated receptacle molded to the elongated flange. ### Claim 8 (depends on 1) The fastener as recited in claim 1, wherein the mating projection mounted on the main pool comprises a bead. ### Claim 9 (depends on 1) The fastener as recited in claim 1, wherein the main pool cover comprises a winter cover. ### Claim 10 A swimming pool peripheral recess cover fastener adapted for use with a peripheral recess having a width, the width extending from a first end of the peripheral recess to a second end, opposite the first end, the fastener comprising: an elongated projection, the elongated projection having a free end, extending across the width of the peripheral recess, and adapted to be received and retained by a mating elongated recess mounted on a main pool cover; and an elongated flange extending from the elongated projection opposite the free end, the elongated flange adapted to be mounted to a peripheral recess cover. ### Claim 11 (depends on 10) The fastener as recited in claim 10, wherein the elongated projection comprises an elongated body having an upper surface and a lower surface, and wherein at least one of the upper surface and the lower surface is beveled. ### Claim 12 (depends on 10) The fastener as recited in claim 10, wherein the fastener comprises an elastomeric fastener. ### Claim 13 (depends on 10) The fastener as recited in claim 10, wherein the peripheral recess comprises a stair assembly. ### Claim 14 (depends on 10) The fastener as recited in claim 10, wherein the elongated projection comprises a bead. ### Claim 15 (depends on 10) The fastener as recited in claim 10, wherein the main pool cover comprises a winter cover. ### Claim 16 (depends on 1) The fastener as recited in claim 1, wherein the elongated flange comprises a thickness between 0.025 inches and 0.050 inches. ### Claim 17 (depends on 1) The fastener as recited in claim 1, wherein the first end and the second end of the peripheral recess each comprise a lateral extremity of the peripheral recess. ### Claim 18 (depends on 1) The fastener as recited in claim 1, wherein the first end and the second end of the peripheral recess each comprise a side wall of the peripheral recess. ### Claim 19 (depends on 10) The fastener as recited in claim 10, wherein the first end and the second end of the peripheral recess each comprise a lateral extremity of the peripheral recess. ### Claim 20 (depends on 10) The fastener as recited in claim 10, wherein the first end and the second end of the peripheral recess each comprise a side wall of the peripheral recess.
