发明名称 Removable protector for locks
摘要 A removable protector for a locking mechanism, such as a door knob or window lock is disclosed. The protector comprises a magnetically attractive member, such as a circular base plate, surrounding the locking mechanism and a housing magnetically attached thereover to discourage access. The housing is dome shaped in configuration and has an aperture to receive a lever whereby the housing may be removed from the circular plate to allow full access to the lock.
