Abstract
Abstract Disclosed is an apparatus for detecting changes in the inclination of a vehicle at rest including a suitable alarm which is activated by a sensing mechanism when a change in the inclination of the vehicle is detected. The sensing mechanism has a reference axis which tends to seek a vertical disposition. A mounting assembly pivotally carries the sensing mechanism and is acted upon by a selectively energized control mechanism to enable the sensing mechanism to seek a vertical disposition regardless of the inclination of the parked vehicle. Both the alarm and the control mechanism can be energized by an independent power source or, if desired, the power source of the vehicle can be utilized for that purpose.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
80 words
Apparatus for detecting changes in the inclination of a vehicle at rest comprising; alarm means, sensing means for detecting changes in the inclination of said vehicle and activating said alarm means, mounting means carrying said sensing means, control means selectively energized to act upon said mounting means to enable said sensing means to seek a vertical plane of reference irrespective of any plane upon which the vehicle may rest, and means to energize said alarm means and said control means.
Claim 2
Dependent Claim
80 words
Apparatus for detecting changes in the inclination of a vehicle at rest comprising; alarm means, sensing means for detecting changes in the inclination of said vehicle and activating said alarm means, mounting means carrying said sensing means, control means selectively energized to act upon said mounting means to enable said sensing means to seek a vertical plane of reference irrespective of any plane upon which the vehicle may rest, and means to energize said alarm means and said control means.
Claim 3
Dependent Claim
56 words
An apparatus, as in claim 1, wherein said sensing means comprises; a tube having a quantity of mercury therein, a first electrical contact extending into said mercury and a second electrical contact positioned immediately above said mercury so that upon a change in the inclination of said tube, said mercury will contact said second electrical contact.
Claim 4
Dependent Claim
50 words
An apparatus, as in claim 1, wherein said mounting means conprises; a shell carrying said sensing means, a rod threadably engaging said shell, a plate having a bore therethrough for the passage of said rod, and a ball having a greater diameter than said bore and threadably engaging said rod.
Claim 5
Dependent Claim
42 words
An apparatus, as in claim 1, wherein said control means comprises; a solenoid having a plunger, and a cap carried by the end of said plunger to engage a portion of said mounting mEans and thereby restrict movement of said sensing means.
Claim 6
Dependent Claim
21 words
An apparatus, as in claim 1, wherein said means for energizing said alarm means and said control means is a battery.
Claim 7
Dependent Claim
32 words
An apparatus, as in claim 1, wherein said alarm means is activated in response to a change in the inclination of the sensing means of at least 3* from its vertical disposition.
Claim 8
Dependent Claim
15 words
An apparatus, as in claim 1, wherein said alarm means is a battery operated siren.
Claim 9
Dependent Claim
21 words
An apparatus, as in claim 1, wherein a timer means deactivates and reactivates said alarm means at intervals of predetermined selection.
Claim 10
Dependent Claim
18 words
An apparatus, as in claim 1, including means to selectively energize said control means and said sensing means.
Claim 11
Dependent Claim
34 words
An apparatus, as in claim 1, wherein said alarm means may also be activated by means responsive to tampering with said vehicle occasioned in a manner other than changing the inclination of said vehicle.
