Mailboxes rotatable to any one of a plurality of orientations

A new and improved mailbox rotatable to any one of a plurality of orientations comprising, in combination:

• a rectangular top plate having an upper surface and a lower surface and with apertures therethrough for coupling with a mailbox thereabove, the top plate also having supplemental apertures;
• a rectangular bottom plate having an upper surface and a lower surface and with apertures therethrough for coupling with a mail box post therebeneath, the bottom plate also having supplemental apertures;
• a circular upper disk having a central axis and having an upper surface and a lower surface and with apertures extending therethrough for coupling the upper surface of the upper disk to the lower surface of the top plate through the supplemental apertures thereof, the lower surface of the upper disk being provided with a downwardly extending hemispherical projection at a predetermined distance from the axis of the upper disk, the upper disk also having interior apertures;
• a circular lower disk having a central axis coaxial with the central axis of the upper disk and having upper and lower surfaces and having a thickness greater than that of the upper disk and with a central bore therethrough, the bore being of a greater diameter in its lower extent to create a shoulder intermediate the upper and lower surfaces;
• apertures formed adjacent to a periphery of the lower disk for securing the lower surface of the lower disk to the upper surface of the bottom plate, the upper surface of the lower disk being formed with a plurality of hemispherical recesses for selectively receiving the projection of the upper disk, the recesses being at the same predetermined distance from the axis of the lower disk as the projection from the axis of the upper disk;
• a cylinder with an enlargement at a lower end positioned within the bore of the lower disk and with threaded apertures extending downwardly into its upper surface for being coupled to the upper disk by bolts extending through the interior apertures of the upper disk;
• and
• a coil spring located within the bore between the enlargement of the cylinder and the shoulder of the lower disk to thereby exert a pressure to hold together the upper and lower disks and, consequently, for holding the projection into a preselected recess of the lower disk.
