Abstract: A quick release bicycle rack has a planar base provided with a generally rectangular upstanding mounting block. The mounting block has a reduced width portion and an enlarged width portion, each provided with a transversely extending cylindrical bore. A conventional quick release spindle, of the type utilized to mount bicycle wheels on the slotted forks of a bicycle frame, is selectively received through one of these transverse bores. In use, one wheel of a bicycle is removed and the slotted forks are clamped against the mounting block by the quick release mechanism. By inserting the quick release spindle through either the reduced or the enlarged width portion of the mounting block, the device may be utilized with bicycles having two different standard fork frame width dimensions. The mounting plate is provided with apertures for the reception of threaded fasteners for securing the mounting block to a horizontal or vertical planar surface.

Abstract: A service signaling device (10) for a mailbox (20) having a door (14) pivotally mounted proximate the bottom (18) of the mailbox. A signal indicating arm (40) is mounted proximate the lower edge (12) of the mailbox door and moves between set and triggered positions. When the arm is in the set position, and secured to the bottom of the mailbox door (14), it indicates a lack of service to the mailbox. When the mailbox door (14) is opened, the arm (40) moves to its triggered position to indicate that service to the mailbox has been completed. An attachment mechanism (26) serves to mount the signal arm (40) on the lower edge of the door. A catch (54) serves to hold the arm (40) in its set position until the door is opened.
