70 is pushed toward toilet bowl 61 as shown in fig4 pivot member 40 also includes a substantially vertical planar portion 41 which engages the rim of the bowl when vacuum cleaner tank 70 is tipped to a substantially horizontal position to protect the porcelain of toilet bowl 61 pivot member 40 is made of hard plastic or any other non abrasive material so that arms 20 and 21 may be readily joined to pivot member 40 elongated metal attachment strips 43 and 44 are riveted to the inner faces of portions 41 and 42 respectively turning now to the details of arms 20 and 21 in the preferred embodiment arms 20 and 21 are shaped and positioned to transfer the load effectively that is each arm 20 21 has a generally trapezoidal shape and each arm 20 21 lies in a plane which is substantially perpendicular to portion 41 of pivot member 40 and which forms an acute angle with portion 42 thereof arms 20 21 are preferably formed of steel rod one length of rod is cut and shaped to integrally form three sides of an arm 20 21 as shown in fig2 specifically the shorter of the non parallel sides of the arm 20 21 side 22 is integrally formed with the longer of the parallel sides side 23 and with the longer of the non parallel sides side 24 a second length of rod forms the shorter of the parallel sides of the arm 20 21 namely side 25 thus two lengths of rod are welded together at two points along side 25.
