The twelfth end 168 of the first exhaust tube 109 is inserted into the ninth end 169 of the main seat exhaust 108. The seventeenth end 171 of the second exhaust tube 110 is inserted into the tenth end 170 of the main seat exhaust 108. The seventh end 173 of the fourth circular hole 119 of the second lid hinge 107 is slid over the eighteenth end 172 of the second exhaust tube 110. The third end 175 of the second circular hole 117 of the second seat hinge 105 is slid over the eighteenth end 172 of the second exhaust tube 110. The thirteenth end 177 of the end cap 111 is slid over the eighteenth end 172 of the second exhaust tube 110. The sixth end 166 of the third circular hole 118 is slid over the eleventh end 167 of the first exhaust tube 109. The second end 164 of the first circular hole 116 of the first seat hinge 104 is slid over the eleventh end 167 of the first exhaust tube 109. The sixteenth end 162 of the elbow joint 112 is slid over the eleventh end 167 of the first exhaust tube 109.
To attach the invention 100 to the toilet 131, the first tab 181 of the first seat hinge 104 is attached to the toilet 131. The second tab 182 is attached to the lower surface 122 of the toilet seat 101. The third tab 183 of the second seat hinge 105 is attached to the toilet 131. The fourth tab 184 of the second seat hinge 105 is attached to the lower surface 122 of the toilet seat 101. Attaching the first seat hinge 104 and the second seat hinge 105 to the toilet 131 is adequate to attach the invention 100 to the toilet 131 in such a manner that the toilet seat 101 can be raised or lowered by rotating the toilet seat 101 using the first seat hinge 104 and the second seat hinge 105 as a pivot point.
To attach the toilet lid 134 to the invention 100, the fifth tab 185 of the first lid hinge 106 is attached to the toilet lid 134 and the sixth tab 186 of the second lid hinge 107 is attached to the toilet lid 134. With this construction, the first lid hinge 106 and the second lid hinge 107 rotate around the first exhaust tube 109 and the second exhaust tube 110 respectively to allow the toilet lid 134 to be raised and lowered.
The fifteenth end 161 of the elbow joint 112 is connected to an exhaust vent 133 using an exhaust pipe 135. The exhaust pipe 135 is beyond the scope of the claims in this disclosure. It is preferred that the exhaust vent 133 incorporate a fan such that gases can be drawn from the toilet basin 132 into and through the invention 100 such that the gases are expelled from the exhaust vent 133.
After installation, the invention 100 is used as a regular toilet seat 101. The toilet seat 101 and the main seat exhaust are formed from molded plastic. Suitable plastics include, but are not limited to, high density polyethylene or polyvinylchloride. The remaining components can be adapted from commercially available parts.
