摘要： A hinge leaf of synthetic plastic material, such as polyethylene or polypropylene, is provided with fastener holes to secure the hinge leaf to the toilet seat or lid or other hinge member, and also has a recess adjacent these holes. Formed integral with the hinge leaf so that it cannot be lost or misplaced and is always at hand is a fastener hole cover which swings downward to conceal the fastener holes and has a tongue or lug which fits snugly into the recess as a detent to hold the cover in place.

摘要： THIS TOILET SEAT HINGE POST HAS A BASE ADAPTED TO REST UPON THE TOILET BOWL REAR PLATFORM AND A LONGITUDINALLYSLOTTED HOLLOW STEM ADAPTED TO EXTEND DOWN INTO ONE OF THE PLATFORM STUD HOLES THEREOF. THE CENTRAL BORE IN THE STEM EXTENDS FROM A COUNTERSINK IN THE TOP OF THE BASE TO A TAPERED OR FLARED COUNTERBORE OF POLYGONAL CROSS-SECTION AT THE LOWER END OF THE STEM. THE SCREW OF AN EXPANDING BOLT HAVING ITS HEAD INSERTED IN THE COUNTERSINK EXTENDS DOWNWARD THROUGH THE CENTRAL BORE AND HAS ITS NUT, ALSO OF POLYGONAL CROSS-SECTION THREADED UPON ITS LOWER END WITHIN THE TAPERED COUNTERBORE AND IS THEREBY PREVENTED FROM ROTATING WHEN THE SCREW IS ROTATED. A HINGE POST EAR RISES FROM THE BASE FOR RECEIVING THE HINGE ROD OF THE TOILET SEAT OR COVER. THE HINGE POST IS INSTALLED BY DROPPING THE STEM INTO THE STUD HOLE AFTER WHICH THE SCREW OF THE BOLT IS TIGHTENED, CAUSING THE NUT THEREON TO TRAVEL UPWARD INTO THE TAPERED COUNTERBORE AND EXPAND THE CIRCUMFERENTIALLYSPACED FINGERS FORMED BY THE LONGITUDINAL SLOTS OF THE STEM INTO TIGHT GRIPPING ENGAGEMENT WITH THE SIDE WALL OF THE STUD HOLE. A REMOVABLE FLANGED CAP IS THEN INSERTED IN THE COUNTERSINK TO CONCEAL THE HEAD OF THE SCREW. TO REMOVE THE HINGE POST THE FOREGOING PROCEDURE IS REVERSED.

摘要： THIS TOILET SEAT HINGE POST HAS A COUNTERBORE FOR THE HEAD OF ITS FASTENER CONCEALED BY A COVER PLATE EXTENDING OVER THE COUNTERBORE AND HAVING PROJECTIONS FRICTIONALLY ENGAGING RECESSES ADJACENT THE COUNTERBORE TO RELEASABLY HOLD THE COVER LATE IN ITS CLOSING POSITION. ONE SUCH COVER PLATE HAS SUCH A PROJECTION NEAR ITS UPPER END AND HAS AN ELONGATION OF THE PLATE EXTENDING AROUND AND BENEATH THE HINGE POST WHERE IT IS APERTURED FOR THE PASSAGE OF THE FASTENER. THIS HINGE POST IS ESPECIALLY SUITABLE FOR INSTALLATION ON MODERN TOILET BOWLS USING TOP-INSERTED FASTENERS WHERE THE SPACE BENEATH THE REARWARD PLATFORM IS INADEQUATE TO RECEIVE A WRENCH FOR TIGHTENING THE NUT ON THE LOWER END. THE CONCEALMENT OF THE FASTENER AND ITS COUNTERBORE BY THE COVER PLATE OF THE PRESENT INVENTION ENHANCES THE CLEANLINESS AND SANITARY CONDITION OF THE HINGE POST, RENDERS IT EASY TO MAINTAIN IN A CLEAN CONDITION, AND ALSO ENHANCES THE APPEARANCE OF THE HINGE POST.
