DETAILED DESCRIPTION


FIG. 1a shows hair entrapment device 10 comprising annular sleeve body 12 having upper open end 14 and lower open end 16 respectively defining a top opening 18 and bottom opening 20; and sidewall 22 extending between upper open end 14 and lower open end 16, comprising inner sleeve wall surface 24 and outer sleeve wall surface 26. Located in the middle of top opening 18 and bottom opening 20 of annular sleeve body 12 is central hub 30 maintained centrally within annular sleeve body 12 by a plurality of spokes 32 which extend from central hub wall 34 of central hub 30 to inner sleeve wall surface 24 of the sidewall 22. Spokes 32 comprise a plurality of tines 40 extending towards top opening 18, and spoke openings 42 are defined between spokes 32, central hub wall 34 and inner sleeve wall surface 24. As shown in FIG. 1b, hair entrapment device 10 may be inserted in drainage well 44 of drain 46 associated with a bathtub, a shower stall, a sink, or any other type of drain of any size. After hair entrapment device 10 is installed in drainage well 44, a water tap associated with the bathtub, the shower stall or the sink is turned on during a cleansing event, such as bathing, a showering or hair washing event. Following, or during, the cleansing event, the water discharged from the bathtub, the shower stall or the sink, flows via top opening 18, spoke openings 42 and bottom opening 20 into drain 46 and any loose hair being carried by the fluid is captured by the plurality of tines 40.


As shown in FIG. 1c, each spoke 32 comprises upstanding wall 50 with tines 40, which may be integrally-formed. Each of tines 40 are separated from other tines 40 by spacing 51 dimensioned to accommodate strands of hair, such human hair or pet hair. The diameter of human hair is generally known to range between 17 μm to 181 μm. In addition, the surrounding wall surface of tines 40 may be rough to enhance the capture of the hair. Sidewall 22 comprises a plurality of crevices 52 formed therethrough and extending for a predefined distance from the upper open end 14. Crevices 52 allow annular sleeve body 12 to be flexible and facilitate the installation of hair entrapment device 10 in drainage well 44 of drain 46. Accordingly, hair entrapment device 10 may be installed in differently sized drains 46. Crevices 52 may comprise different dimensions, which may impact the level of flexibility of annular sleeve body 12.


Looking at FIGS. 1d-1g, central hub 30 comprises knob 60, neck 62 and belly 64. In one example, knob 60 and neck 62 are positioned above top opening 18. Knob 60 may be grasped by a hand or a tool when installing in drain 46 or extricating from drain 46. In one example, belly 64 comprises hollow portion 66. FIG. 1h shows a plurality of hair entrapment devices 10 stacked on top of each other, in which knob 60, neck 62 of one device 10 is received by hollow portion 66 of another hair entrapment device 10. Accordingly, hollow portion 66 facilitates stacking of hair entrapment device 10 for packaging, transportation, or storage when not is use.


In operation, a downward force is applied on hair entrapment device 10 to urge hair entrapment device 10 downwardly into drainage well 44 such that outer sleeve wall surface 26 of annular sleeve body 12 is in tight, sealing engagement with the drain wall 68 of drainage well 44. In one example, the force is applied to knob 60 and/or spokes 32. Fluid flows via top opening 18, spoke openings 42 and bottom opening 20 and loose hair is captured by the plurality of tines 40. Spokes 32 and spoke openings 42 are dimensioned such that the flow of water around spokes 32 into drainage well 44 is not substantially limited, and therefore flows at an acceptable rate that is substantially similar to the rate of flow without hair entrapment device 10 installed within drainage well 44. Accordingly, there is no substantial difference in the flow rate with or without hair entrapment device 10 installed within drainage well 44. In one example, hair entrapment device 10 is urged into drainage well 44 until bottom portion of sidewall 22 and bottom portions of spokes 32 are adjacent to, or abut, cross members 69 of drain 46.


In one implementation, sidewall 22 is substantially frustoconical, and tapering from upper open end 14 and lower open end 16. Frustoconical sidewall 22 aids in securement of hair entrapment device 10 within drainage well 44. Accordingly, hair entrapment device 10 is able to fit into a plurality of differently sized drains 46. For example, a portion of the tapered lower end of annular sleeve body 12 may be received within drainage well 44 while the upper portion of annular sleeve body 12 is free of drainage well 44.


As noted above, knob 60 may be grasped by a tool when installing in drainage well 44 or extricating hair entrapment device 10 from drainage well 44. FIGS. 2a-2e show various views of exemplary tool 70 which comprises unitary body 72 dimensioned to be received by hair entrapment device 10 via upper open end 14. Unitary body 72 comprises top end 74 with top wall 75, and bottom end 76 with bottom wall 78, and surrounding wall 80. Central aperture 81 extends between top wall 75 and bottom wall 78, and a plurality of fingers 82 formed from top wall 75 and bottom wall 78, with fingers 82 separated from each other by cut-outs 84 which extend from surrounding wall 80 to aperture wall 85 defining central aperture 81. As such, the shape and dimensions of the plurality of fingers 82 is complementary to the shape and dimensions of spoke openings 42, while the shape and dimensions of cut-outs 84 correspond to the shape and dimensions of spokes 32. Top wall 75 also includes handle 88 for facilitating the handling of tool 70 when installing hair entrapment device 10 in drainage well 44 or extricating hair entrapment device 10 from drainage well 46.


The operation of hair entrapment device 10 and tool 70 will now be described. In one example, before a cleansing event, such as taking a shower or washing one's hair or other hair shedding event, hair entrapment device 10 is installed in drainage well 44 associated with drain 46. When installed, outer sleeve wall surface 26 of hair entrapment device 10 is in tight, sealing engagement with the drain wall 68 of drainage well 44 with the water. During, or after, the hair shedding event loose hair that would normally flow into drainage well 44 is captured by the plurality of tines 40 of hair entrapment device 10. More specifically, a shed hair strand is carried by the flowing water towards drain 46, and as the hair strand advances into drainage well 44 a portion of the hair strand enters one or more spacings 51 of tines 40 associated with one or more of spokes 32. As the water continues to flow into drainage well 44 other portions of the hair strand also enter one or more spacings 51 of tines 40 associated with one or more of spokes 32. As the water continues to flow the process repeats itself and a sufficient portion of the hair strand is retained within spacings 51 of tines 40 such that the strand of hair is thereby prevented from going down drain 46, and the hair strand accumulates within hair entrapment device 10. Furthermore, any swirling action of the water as it enters drainage well 46 further enhances the capture of the hair strand by tines 40.


Following the hair shedding event, the accumulated, tangled loose hair may need to be removed from hair entrapment device 10 to permit re-use, alternatively, a clean or new device 10 may be used instead. Preferably, hair entrapment device 10 is extricated from drainage well 44 first. While this may be performed by inserting one's hand into drainage well 44 to grab hair entrapment device 10 by knob 60 and applying an upward force, a tool may be used, such as tool 70. Accordingly, tool 70 may be introduced into the mouth of drainage well 44, and with central aperture 81 aligned with central hub 30, cut-outs 84 aligned with spokes 32, and the plurality of fingers 82 aligned with spoke openings 42, a downward force is applied to handle 88. As the force is applied, knob 60 and neck 62 of central hub 30 are forced through aperture 86, and spokes 32 are received by cut-outs 84, and the plurality of fingers 82 are received by spoke openings 42, and belly 64 abuts aperture wall 85 of the plurality of fingers 82. Tool 70 is caused to travel down along inner sleeve wall surface 24 of sidewall 22 until bottom wall 78 of the plurality of fingers 82 is adjacent to lower open end 16, or at least until the top edge of tines 40 is adjacent to the top section of cut-outs 84, while taking into account the captured hair strands which is trapped therebetween, thereby placing tool 70 in a deployed position. From the deployed position, the combination of hair entrapment device 10 and tool 70 may be removed from drainage well 44 by pinching knob 60 and applying a lifting force to cause outer sleeve wall surface 26 of annular sleeve body 12 to slide upwardly along drain wall 68 until the combination of hair entrapment device 10 and tool 70 are out of drainage well 44, along with the trapped hair.


In one implementation, hair entrapment device 90 as shown in FIGS. 3a-3d comprises annular sleeve body 12, and sidewall 22 comprising inner sleeve wall surface 24 and outer sleeve wall surface 26. Hair entrapment device 90 is similar to hair entrapment device 10, however, sidewall 22 of hair entrapment device 90 comprises a plurality of upstanding posts 91 extending from upper open end 14. Looking at FIG. 4, there is shown hair entrapment device 90 that has been removed from drainage well 44 following a cleansing event in which hair 92 was shed. Loose hair 92 otherwise destined to flow down drain 46 associated with bathtub 93 and potentially result in a blockage of drain 46 is seen to have been snagged by tines 40 of hair entrapment device 90. Also, the plurality of upstanding posts 91 also snag loose hair 92, especially as water swirls down drain 46. The swirling effect caused by the water causes loose hair 92 to swirl too, and in doing so loose hair 92 wraps around posts 91 and/or tines 40, as shown in FIG. 4. Hair entrapment device 90 may be removed from drainage well 46 and the accumulated tangled loose hair 92 is removed therefrom, thereby permitting re-use of hair entrapment device 90. Alternatively, hair entrapment device 90 with the accumulated hair may be disposed of.



FIG. 5 shows tool 94 installed within hair entrapment device 90 for facilitating installation of hair entrapment device 90 in drainage well 44 or extrication of hair entrapment device 10 from drainage well 44. Tool 94 is similar to tool 70, and comprises unitary body 72 dimensioned to be received by hair entrapment device 90 via upper open end 14, with surrounding wall 80. A plurality of fingers 82 are formed from adjacent top wall 75 and bottom wall 78 and fingers 82 are separated from each other by primary cut-outs 84, with central aperture 81 extending between top wall 75 and bottom wall 78. Accordingly, primary cut-outs 84 extend from surrounding wall 80 to aperture wall 85 defining central aperture 81. As such, the shape and dimension of the plurality of fingers 82 is complementary to the shape and dimension of spokes 32 and spoke openings 42. Top wall 75 also includes handle 88 for facilitating installing in drain 46 or extricating hair entrapment device 10 from drainage well 44. Secondary cut-outs 95 extend from top wall 75 to bottom wall, and secondary cut-outs 95 are dimensioned to receive upstanding posts 91 when tool 94 is installed within hair entrapment device 90, as shown in FIG. 5.


In one implementation, there is shown in FIGS. 6a and 6b hair entrapment device 100, which is similar to hair entrapment device 10 and comprises like elements. Hair entrapment device 100 comprises annular sleeve body 112 having upper open end 114 and lower open end 116 respectively defining top opening 118 and bottom opening 120. Sidewall 122 comprises inner wall surface 124 and outer wall surface 126, extends between upper open end 114 and lower open end 116. Located in the middle of top opening 118 and bottom opening 120 of annular sleeve body 112 is central hub 130 maintained centrally within annular sleeve body 112 by a plurality of spokes 132 extending from central hub wall 134 of central hub 130 to inner wall surface 124 of the sidewall 122. Spokes 132 comprise a plurality of integrally formed tines 140 extending towards top opening 118, and spoke openings 142 are defined between spokes 122, central hub wall 134 and inner wall surface 124. Sidewall 122 comprises a plurality of upstanding posts 150 extending from upper open end 114. Sidewall 122 also comprises a plurality of crevices 152 formed therethrough and extending for a predefined distance from the upper open end 114. Crevices 152 allow annular sleeve body 112 to be flexible and facilitate the installation of hair entrapment device 100 in drainage well 44 of drain 46.


Once installed within drainage well 44, tines 140 of hair entrapment device 100 snag loose hair 92 carried by water during or after a hair shedding event, that is, loose hair 92 that would otherwise flow down drain 46 and potential result in a blockage of drain 46. The plurality of upstanding posts 150 also snag loose hair 92, especially as water swirls down drain 46. The swirling effect caused by the water causes loose hair 92 to swirl too, and in doing so loose hair 92 wraps around posts 150 and/or tines 140. Following the hair shedding event, tangled loose hair 92 is removed from hair entrapment device 100.


As shown in FIGS. 6a and 6b, central hub 130 comprises knob 160, neck 162 and belly 164.

As such, the shape and dimension of the plurality of fingers 182 is complementary to the shape and dimension of spokes 140 and spoke openings 142. Similarly, primary cut-outs 184 are dimensioned to receive spokes 132. Top wall 175 also includes handle 188 for facilitating installing in drain 46 or extricating hair entrapment device 10 from drain 46. Secondary cut-outs 190 extend from top wall 175 to bottom wall, and secondary cut-outs 190 are dimensioned to receive upstanding posts 150 when tool 170 is installed within hair entrapment device 100.
