Abstract
Abstract A protective cover for a shackle lock is integrally made of a resilient material having an upper surface with a pair of spaced apertures defined by ring seals integrally molded to the top and surrounded by an accordian fold. Downwardly depending sidewalls fit over the body of a shackle lock and terminate with a peripheral bead adapted to sealably engage a bottom plug having a corresponding recess such that when the plug is fitted into the open bottom a tight seal is formed. In the preferred embodiment, a tether is coupled to the bottom and is detachably secured to one of the walls of the cover. The accordian fold surrounding the spaced apertures permits the apertures to align with shackle bars of a variety of lock sizes while the ring provides a tight seal against the shackle bar preventing entry of vapors, dirt, moisture, and the like.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
A protective cover for a shackle type lock comprising: a body having a one-piece, integral top and downwardly depending side walls defining a lock encompassing enclosure with an open bottom, said top including a pair of spaced apertures formed through said top and defined by ring seals integral with said top, and an accordian fold surrounding each of said ring seals to permit linear and rotational flection therebetween, said enclosure top and side wall being resilient to permit lateral displacement of said ring seals to accommodate variously sized locks, and permit flexing of said side walls to facilitate assembly of a lock in said integrally formed enclosure, and to provide access to side mounted lock tumblers; and a closure shaped to sealably fit within the open bottom of said enclosure.
Claim 2
Dependent Claim
130 words
A protective cover for a shackle type lock comprising: a body having a one-piece, integral top and downwardly depending side walls defining a lock encompassing enclosure with an open bottom, said top including a pair of spaced apertures formed through said top and defined by ring seals integral with said top, and an accordian fold surrounding each of said ring seals to permit linear and rotational flection therebetween, said enclosure top and side wall being resilient to permit lateral displacement of said ring seals to accommodate variously sized locks, and permit flexing of said side walls to facilitate assembly of a lock in said integrally formed enclosure, and to provide access to side mounted lock tumblers; and a closure shaped to sealably fit within the open bottom of said enclosure.
Claim 3
Dependent Claim
23 words
The cover as defined in claim 1 wherein said side walls include a bead extending around the periphery thereof near said open bottom.
Claim 4
Dependent Claim
32 words
The cover as defined in claim 2 wherein said closure comprises a plug including a channel for sealably receiving said bead for securing said plug within said open bottom of said enclosure.
Claim 5
Dependent Claim
27 words
The cover as defined in claim 3 wherein said plug includes a tapered upper end facilitating insertion of said plug into said open bottom of said enclosure.
Claim 6
Dependent Claim
19 words
The cover as defined in claim 4 and further including a tether coupling said plug to said side walls.
Claim 7
Dependent Claim
25 words
The cover as defined in claim 1 wherein said closure comprises a plug having a core of low density material coated with a resilient material.
Claim 8
Dependent Claim
34 words
The cover as defined in claim 1 wherein said side walls have a length which extends beyond a lock for use with said cover to define a cavity between the lock and said closure.
Claim 9
Dependent Claim
30 words
The cover as defined in claim 7 wherein said closure has a core of sufficiently large volume low density material to provide floatation of said cover and a lock therein.
Claim 10
Dependent Claim
20 words
The cover as defined in claim 8 and further including a detachable tether extending between said body and said closure.
Claim 11
Dependent Claim
21 words
