Theft-deterrent bracket for smoke alarms

Claim 2

A theft-deterrent bracket for a smoke alarm having a cover and a fastening device engageable with a room surface for attaching said alarm to said surface, said bracket comprising: (A) a first rigid part including affixing means for holding said first part adjacent to said room surface; (B) a second rigid part; (C) holding means permanently coupled to said first and said second parts for retaining said first and second parts in proximity to each other; and p1 (D) locking means permanently affixed to at least one of said first and second parts and having first and second configurations, for, in the first and second configurations, fixedly retaining said first and second parts in contact with each other, said locking means including means for limiting its unauthorized movement from said first to said second configurations, said first and second parts, when retained in contact with each other by said locking means and with said first part held adjacent to said room surface by said affixing means, including (a) coupling means adapted to maintain said first and second parts in a fixed orientation relative to said cover of said alarm and, when thus maintained in said fixed orientation relative to said cover by said coupling means, adapted to prevent disengagement of said fastening device to allow the removal of said cover from said room surface and (b) protecting means for substantially preventing access to said locking means.

Claim 3

The bracket of claim 1 wherein said first and second parts, when fixedly retained in contact with each other by said locking means and when maintained in a fixed orientation relative to said cover by said coupling means, are adapted to maintain said cover in the form of a nonopenable enclosed case enclosing said fastening device.

Claim 4

The bracket of claim 2 wherein said first and second parts have elongated shapes and a composition of metal and, when retained in contact with each other by said locking means, have a shape to define a space therebetween sufficiently large to barely allow said alarm to fit therein.

Claim 5

The bracket of claim 3 wherein said locking means includes a cam lock permanently affixed to said second part.

Claim 6

The bracket of claim 3 wherein said holding means includes a hinge attached to both said first and second parts.

Claim 7

A smoke alarm and theft-deterrent bracket combination comprising (1) a smoke alarm having a cover with two portions engageable with each other and a fastening device engageable with a room surface and having screws extending from the inside of said cover to the outside of said cover for attaching said alarm to said surface and (2) a bracket comprising: (A) a first rigid part including affixing means for holding said first part adjacent to said room surface; (B) a second rigid part; (C) holding means permanently coupled to said first and second parts for retaining said first and second parts in proximity to each other; and (D) locking means permanently affixed to at least one of said first and second configurations for, in the first of said configurations, fixedly retaining said first and second parts in contact with each other, said locking means including means for limiting its unauthorized movement from said first to said second configurations, said first and second parts, when retained in contact with each other by said locking means, including coupling means for maintaining said first and second parts in a fixed orientation relative to said cover of said alarm and, when thus maintained in said first orientation relative to said cover by said coupling means, preventing disengagement of said fastening device to allow the removal of said cover from said room surface and substantially preventing access to said locking means, and said first and second parts, when fixedly retained in contact with each other by said locking means and when maintained by said coupling means in a fixed orientation relative to said cover, preventing the disengagement of said first and second portions from each other.

Claim 8

A smoke alarm and theft-deterrent bracket combination comprising (1) a smoke alarm having a cover with two portions engageable with each other and a fastening device engageable with a room surface and having screws extending from the inside of said cover to the outside of said cover for attaching said alarm to said surface and (2) a bracket comprising: (A) a first rigid part including affixing means for holding said first part adjacent to said room surface; (B) a second rigid part; (C) holding means permanently coupled to said first and second parts for retaining said first and second parts in proximity to each other; and (D) locking means permanently affixed to at least one of said first and second configurations for, in the first of said configurations, fixedly retaining said first and second parts in contact with each other, said locking means including means for limiting its unauthorized movement from said first to said second configurations, said first and second parts, when retained in contact with each other by said locking means, including coupling means for maintaining said first and second parts in a fixed orientation relative to said cover of said alarm and, when thus maintained in said first orientation relative to said cover by said coupling means, preventing disengagement of said fastening device to allow the removal of said cover from said room surface and substantially preventing access to said locking means, and said first and second parts, when fixedly retained in contact with each other by said locking means and when maintained by said coupling means in a fixed orientation relative to said cover, preventing the disengagement of said first and second portions from each other.

Claim 9

The combination of claim 6 wherein, when one of said portions of said cover fits inside the other of said portions and said portions are engaged with each other, said first and second parts, when fixedly retained in contact with each other by said locking means and maintained by said coupling means in a fixed orientation relative to said cover, prevent the removal of said one portion from the inside of said other portion.

Claim 10

The combination of claim 7 wherein said first part and said second part, when fixedly retained in contact with each other by said locking means and when maintained by said coupling means in a fixed orientation relative to said cover, completely surround said alarm in at least one direction.

Claim 11

The combination of claim 8 wherein said coupling means includes holes passing through said first part and screws passing through said holes and through openings in at least one portion of said cover.

Claim 12

The combination of claim 9 wherein said screws of said coupling means are said screws of said fastening device, and said affixing means includes said coupling means with said screws passing through openings in said cover, said holes in said first part, and into said room surface, to attach said cover and said first part to said wall and maintain said first part and said cover in a fixed orientation relative to each other.

Claim 13

The combination of claim 10 wherein said holding means includes a hinge attached to both said first and said second parts.
