DESCRIPTION OF THE INVENTION

(26) For purposes of the description hereinafter, spatial orientation terms, if used, shall relate to the referenced embodiment as it is oriented in the accompanying drawing figures or otherwise described in the following detailed description. However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and embodiments. It is also to be understood that the specific devices illustrated in the accompanying drawing figures and described herein are simply exemplary and should not be considered as limiting.

(27) As shown in FIG. 1, the conventional sink structure comprises a sink 10 having a basin 12, which is capable of allowing water to drain through a P-trap 14, having a pair of vertically spaced apart legs 16 connected by a U-shaped bend 18. Connected to the P-trap is an L-shaped waste arm 20, leading to a drain pipe 22, which is located within the wall 24. A nut 26 is provided for securing the waste arm 20 to the P-trap 14. Also located beneath the basin are the supply pipes 28 for the hot and cold water each of which includes a shut-off valve 30.

(28) FIGS. 2 and 3 show a cover 32 according to the present invention for covering the P-trap 14. The shape of the cover 32 substantially corresponds to the shape of the P-trap having a longer, generally cylindrical leg 34 attached to a shorter, generally cylindrical leg 36 by a U-shaped bend 38. A longitudinal slit 40 extends from the top 42 of the longer leg 34 down its sidewall around the inside portion of the U-shaped bend 38 and up the sidewall of the shorter leg 36 to the top 44 of the shorter leg 36. This slit allows the flexible material of the cover 32 to be spread apart and fitted on the P-trap pipe.

(29) The interior of the longer leg 34 may include inwardly extending flanges 41. The flanges 41 may take any suitable size shape and number as long as they act as a spacer between the cover 32 and the pipe.

(30) An outwardly extending flange 46 is located on each edge of the slit 40 along a portion of the longer leg 34. The flanges 46 extend along the sidewall of the longer leg 34 from the top 42 of the longer leg 34 to a distance above the top 44 of the shorter leg 36. A plurality of protrusions 48 extend outwardly from the outer surface 50 of each flange. The protrusions 48 are spaced apart from one another, and each protrusion 48 on one flange 46 is aligned with a protrusion 48 on the other flange 46.

(31) As shown in FIGS. 4 and 5, each protrusion 48 has a first central opening 52 having a first open end 54 at the outermost end 56 of the protrusion 48 and a second open end 58 connected to a first open end 60 of a second central opening 62. The second central opening 62 extends through the innermost end 64 of the protrusion 48 and into the flange 46. The second open end 66 of the second central opening 62 is connected to the first open end 68 of a third central opening 70 that extends through the flange 46 such that the second open end 72 of the third central opening 70 is located on the inner surface 74 of the flange 46.

(32) The first central opening 52, second central opening 62, and third central opening 70 may take any suitable size and shape for accommodating the fastener 76 which will be described later, including but not limited to openings having a circular (as shown in FIGS. 2-5) or square cross-section as viewed in a plane perpendicular to the central longitudinal axis X of the protrusion 48. Depending on the shape of the first central opening 52, second central opening 62, and third central opening 70, the maximum diameter or width D1 of the first central opening 52 as viewed in cross-section in a plane perpendicular to the central longitudinal axis X of the protrusion 48 and the maximum diameter or width D3 of the third central opening 70 as viewed in cross-section in a plane perpendicular to the central longitudinal axis X of the protrusion 48 is larger than the maximum diameter or width D2 of the second central opening 62 as viewed in cross-section in a plane perpendicular to the central longitudinal axis X of the protrusion 48. The first central opening 52 may have a maximum diameter or width D1 as viewed in cross-section in a plane perpendicular to the central longitudinal axis X of the protrusion 48 equal to the maximum diameter or width D3 of the third central opening 70 as viewed in cross-section in a plane perpendicular to the central longitudinal axis X of the protrusion 48 as shown in FIGS. 4 and 5.

(33) FIGS. 6-9 show a fastener 76 that is used to secure the cover 32 around the P-trap 14. The fastener 76 has five portions.

(34) The first portion 78 may take any suitable shape or size as long as it can be accommodated in the first central opening 52 of the protrusion 48 and cannot pass into the second central opening 62 without deformation of the second central opening 62. Such shapes include, but are not limited to, shapes having a circular or square cross-section as viewed in a plane perpendicular to the central longitudinal axis Y of the fastener 76. As shown in FIGS. 6-9, the first portion 78 of the fastener 76 has a first end 80, a second end 82, and a generally cylindrical sidewall 84 extending therebetween.

(35) The second portion 86 may take any suitable shape or size as long as it can be accommodated in the second central opening 62 of the protrusion 48. Such shapes include, but are not limited to, shapes having a circular or square cross-section as viewed in a plane perpendicular to the central longitudinal axis Y of the fastener 76. As shown in FIGS. 6-9, the second portion 86 of the fastener 76 may have a first end 88, a second end 90, and a generally cylindrical sidewall 92 extending therebetween. The first end 88 of the second portion 86 of the fastener 76 is connected to the second end 82 of the first portion 78 of the fastener 76. As with the first central opening 52 and the second central opening 62 of the protrusion 46, the first portion 78 of the fastener 76 has a maximum diameter or width d1 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 that is greater than the maximum diameter or width d2 of the second portion 86 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76.

(36) The third portion 94 may take any suitable shape or size as long as it can be accommodated in the combination of the third central opening 70 of one protrusion 48 and the third central opening 70 of the opposing protrusion 48 when the flanges 46 are mated and, when the second central opening 62 is deformed, can pass through the second central opening 62. Such shapes include, but are not limited to, shapes having a circular or square cross-section as viewed in a plane perpendicular to the central longitudinal axis Y of the fastener 76. As shown in FIGS. 6-9, the third portion 94 of the fastener 76 has three sections.

(37) The first section 96 is attached to the second end 90 of the second portion 86 of the fastener 76. The first end 98 of the first section 96 has a maximum width or diameter as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 that is smaller than the maximum width or diameter of the second end 100 of the first section 96 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 and a radially outward sloping sidewall 102 extending from the first end 98 to the second end 100.

(38) The second section 104 has a first end 106, a second end 108, and a generally cylindrical sidewall 110 with a width or diameter d3 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 substantially equal to the width or diameter of the second end 100 of the first section 96 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76.

(39) The third section 112 has a first end 114 and a second end 116 where the width or diameter of the first end 114 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 is larger than the width or diameter of the second end 116 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76. A radially inwardly sloping sidewall 118 extends from the first end 114 to the second end 116. The first end 114 of the third section 112 is connected to the second end 108 of the second section 104 and has a width or diameter as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 that is substantially equal to the width or diameter d2 of the second end 108 of the second section 104 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76. The first section 96 and third section 112 are generally mirror images attached to opposite sides of the second section 104.

(40) The fourth portion 120 may take any suitable shape or size as long as it can be accommodated in the second central opening 62 of the protrusion 48. Such shapes include, but are not limited to, shapes having a circular or square cross-section as viewed in a plane perpendicular to the central longitudinal axis Y of the fastener 76. As shown in FIGS. 4-6, the fourth portion 120 of the fastener 76 may have a first end 122, a second end 124, and a generally cylindrical sidewall 126 extending therebetween. The first end 122 of the fourth portion 120 of the fastener 76 is connected to the second end 116 of the third section 112 of the third portion 94 of the fastener 76.

(41) The fifth portion 128 may take any suitable shape or size as long as it can be accommodated in the first central opening 52 of the protrusion 48 and, when the second central opening 62 is deformed, can pass through the second central opening 62. Such shapes include, but are not limited to, shapes having a circular or square cross-section as viewed in a plane perpendicular to the central longitudinal axis Y of the fastener 76. As shown in FIGS. 6-9, the fifth portion 128 of the fastener 76 has three sections.

(42) The first section 130 is attached to the second end 124 of the fourth portion 120 of the fastener 76. The first end 132 of the first section 130 has a width or diameter that is smaller as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 than the width or diameter of the second end 134 of the first section 130 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 and a radially outwardly sloping sidewall 136 extending from the first end 132 to the second end 134.

(43) The second section 138 has a first end 140, a second end 142, and a generally convex rounded sidewall 144. The width or diameter of the first end 140 and the second end 142 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 are substantially equal to the width or diameter of the second end 134 of the first section 130 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76. The sidewall 146 of the second section 138 is convexly rounded such that the maximum width or diameter d5 of the second section 138 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 is located at the midpoint between the first end 140 and the second end 142 of the second section 138.

(44) The third section 146 is generally cone-shaped and has a first end 148 with a width or diameter as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 substantially equal to the width or diameter of the second end 142 of the second section 138 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 to which it is attached. A radially inwardly sloping sidewall 148 extends from the first end 148 to a second end 150 which is substantially pointed.

(45) As with the first central opening 52 and the second central opening 62 of the protrusion 46, the fourth portion 120 of the fastener 76 has a maximum width or diameter d4 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76 that is less than the maximum width or diameter d5 of the fifth portion 128 as viewed in cross-section in a plane perpendicular to the central longitudinal axis Y of the fastener 76.

(46) The fastener 76 may be used in two ways to attach the flanges 46 to one another and seal the slit 40. In a first embodiment, the fastener 76 is preassembled with the cover 32. The first portion 78 of the fastener 76 is located in the first central opening 52 of a protrusion 48 on one of the flanges 46, the second portion 86 of the fastener 76 is located in the second central opening 62 of the protrusion 48, and at least a portion of the third portion 94 of the fastener 76 is located in the third central opening 70 of the protrusion 48. The third portion 94 of the fastener 76 keeps the fastener 76 from falling out of the protrusion 48 when it abuts the second open end 66 of the second central opening 62.

(47) As shown in FIGS. 10 and 11, after the cover 32 is placed around the P-trap 14, the fifth portion 128 of the fastener 76 is inserted into the third central opening 70 of the corresponding protrusion 48 on the opposing flange 46. By applying opposing forces to the outermost ends 56 of the protrusions 48, the flanges 46 are snapped together when the fifth portion 128 of the fastener 76 enters the first central opening 52 of the opposing flange 46. The cone-shaped third section 146 of the fifth portion 128 of the fastener 76 acts to force open the second central opening 62 of the protrusion 48 allowing the fifth portion 128 of the fastener 76 to pass through. Once the fifth portion 128 of the fastener 76 has passed through the second central opening 62 of the protrusion 48 and is no longer applying force to the second central opening 62, the second central opening 62 returns to its original configuration around the fourth portion 120 of the fastener 76.

(48) Alternatively, the fastener 76 could be supplied separately from the cover 32. After the cover 32 is placed around the P-trap 14, the fifth portion 128 of the fastener 76 is inserted into the first central opening 52 of a protrusion 48 on one of the flanges 46. When force is applied to the first end 80 of the first portion 78 of the fastener 76, the cone-shaped third section 146 of the fifth portion 128 of the fastener 76 acts to force open the second central opening 62 of the protrusion 48 allowing the fifth portion 128 of the fastener 76 to pass through. Once the fifth portion 128 of the fastener 76 has passed through the second central opening 62 of the protrusion 48 and is no longer applying force to the second central opening 62, the second central opening 62 returns to its original configuration around the fourth portion 120 of the fastener 76. As further force is applied to the first end 80 of the first portion 78 of the fastener 76, the third section 112 of the third portion 94 of the fastener 76 acts to force open the second central opening 62 of the protrusion 48 allowing the third portion 94 of the fastener 76 to pass through. Once the third portion 94 of the fastener 76 has passed through the second central opening 62 of the protrusion 48 and is no longer applying force to the second central opening 62, the second central opening 62 returns to its original configuration around the second portion 86 of the fastener 76. The flanges 46 can then be snapped together by applying opposing forces to the outermost ends 56 of the opposing protrusions 48 as described above.

(49) As shown in FIGS. 2, 3, 12, and 13, the cover 32 includes a drain 154 in the bottom of the U-shaped bend 38 to allow condensate to drain from the cover 32. The drain 154 includes a central drain hole 156 surrounded by a groove 158. The drain hole 156 may take any suitable shape including, but not limited to, circular, square, and polygonal. The groove 158 may take any suitable shape including, but not limited to, circular, square, and polygonal, and may correspond to the shape of the drain hole 156. The groove 158 includes sections 160 that only extend partially through the sidewall of the U-shaped bend 38 and sections 162 that extend all the way through the sidewall of the U-shaped bend 38. The groove 158 may have any number of partially extending sections 160 and any number of fully extending sections 162. In the embodiment shown in FIGS. 2, 3, 12, and 13, the groove 158 is circular and includes two fully extending sections 162 having a curved shape.

(50) A cover 164 for covering the waste arm 20 is shown in FIGS. 14-17. Corresponding features of this waste arm cover 164 are given the same reference numerals as described above with respect to the P-trap cover 32. The shape of the cover 164 substantially corresponds to the shape of the waste arm 20 having a generally cylindrical leg 166 attached to a U-shaped bend 168. A longitudinal slit 40 extends from the top 169 of the leg 166 down its sidewall and around the inside portion of the U-shaped bend 168.

(51) The interior of the leg 166 may include inwardly extending flanges 41. The flanges 41 may take any suitable size shape and number as long as they act as a spacer between the cover 164 and the pipe.

(52) An outwardly extending flange 46 is located on each edge of the slit 40 along the length of the leg 166. A plurality of protrusions 48 extend outwardly from the outer surface 50 of each flange 48. The protrusions 48 are spaced apart from one another, and each protrusion 48 on one flange 46 is aligned with a protrusion 48 on the other flange 46.

(53) As shown in FIG. 17, each protrusion 48 has a first central opening 52, a second central opening 62, and a third central opening 70 as described above. The flanges 46 are attached to one another using the fastener 76 as described above.

Corresponding features of this supply pipe cover 170 are given the same reference numerals as described above with respect to the P-trap cover 32. The cover 170 has a T-shape including a longitudinal, substantially cylindrical leg 172 and a transverse, substantially cylindrical leg 174 that substantially correspond to the shape of the supply pipe 28 including the shut-off valve 30. The transverse leg 174 has a first arm 176 and a second arm 178 that extend in opposite directions from the longitudinal leg 172. The end 180 of the first arm 176 is open and the end 182 of the second arm 178 is substantially closed. A longitudinal slit 40 extends from the top 175 of the longitudinal leg 172, down its sidewall, and across the first arm 176 of the transverse leg 174.

(55) An outwardly extending flange 46 is located on each edge of the slit 40 along the entire length of the slit 40. A plurality of protrusions 48 extend outwardly from the outer surface 50 of each flange 46. The protrusions 48 are spaced apart from one another, and each protrusion 48 on one flange 46 is aligned with a protrusion 48 on the other flange 46.

(56) Each protrusion 48 has a first central opening 52, a second central opening 62, and a third central opening 70 as described above. The flanges 46 are attached to one another using the fastener 76 as described above.

(57) As shown in FIGS. 18-22, the cover 170 includes a drain 154 in the end 180 of the second arm 178 of the transverse leg 174 to allow condensate to drain from the cover 170. The drain 154 includes a central drain hole 156 surrounded by a groove 158 as described above.

(58) A cover 184 for covering an offset drain is shown in FIGS. 23-25. Corresponding features of this offset drain cover 184 are given the same reference numerals as described above with respect to the P-trap cover 32. The shape of the cover 184 substantially corresponds to the shape of an offset drain having a first right angle portion 186 and a second right angle portion 190 with a generally longitudinal cylindrical leg 188 extending therebetween. The first right angle portion 186 and the second right angle portion 190 face in opposing directions. A longitudinal slit 40 extends along the first right angle portion 186, along the cylindrical leg 188, and along the second right angle portion 190.

(59) The interior of the leg 188 may include inwardly extending flanges 41. The flanges 41 may take any suitable size shape and number as long as they act as a spacer between the cover 184 and the pipe.

(60) An outwardly extending flange 46 is located on each edge of the slit 40 along the curved section of the first right angle portion 186 and partially along the leg 188.
