Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
177 words
A vehicle burglar alarm system, usable in a vehicle having a passenger compartment and at least one non-passenger compartment, comprising: 1. an alarm circuit, comprising: a. alarm means, responsive to an applied electrical voltage, for signalling an alarm; b. means for supplying said electrical voltage; c. first switching means, responsive to the opening of said passenger compartment, for applying said electrical voltage to said alarm signalling means; and d. second switching means, closed in response to the opening of said non-passenger compartment, for applying said electrical voltage to said alarm signalling means when closed; 2. control switching means located in said non-passenger compartment, for selectively opening or closing said alarm circuit; 3. and a single time delay for delaying application of said electrical voltage to said alarm means for a selected time after closing of said control switching means when said second switching means is closed, and also for delaying application of said electrical voltage to said alarm means for a selected time after closing of said second switching means when said control switching means is closed.
Claim 2
Dependent Claim
177 words
A vehicle burglar alarm system, usable in a vehicle having a passenger compartment and at least one non-passenger compartment, comprising: 1. an alarm circuit, comprising: a. alarm means, responsive to an applied electrical voltage, for signalling an alarm; b. means for supplying said electrical voltage; c. first switching means, responsive to the opening of said passenger compartment, for applying said electrical voltage to said alarm signalling means; and d. second switching means, closed in response to the opening of said non-passenger compartment, for applying said electrical voltage to said alarm signalling means when closed; 2. control switching means located in said non-passenger compartment, for selectively opening or closing said alarm circuit; 3. and a single time delay for delaying application of said electrical voltage to said alarm means for a selected time after closing of said control switching means when said second switching means is closed, and also for delaying application of said electrical voltage to said alarm means for a selected time after closing of said second switching means when said control switching means is closed.
Claim 3
Dependent Claim
47 words
An alarm system as specified in claim 1, wherein said alarm means includes a latching relay, for causing a continuous signalling of said alarm, connected to said voltage supplying means and responsive to the application of said electrical voltage by either said first or second switching means.
Claim 4
Dependent Claim
64 words
An alarm system as specified in claim 1, wherein said vehicle has more than one non-passenger compartment and wherein said control switching means is located in a selected one of said non-passenger compartments and wherein said alarm circuit additionally includes switch means, responsive to the opening of at least one of the remaining non-passenger compartments, for applying said electrical voltage to said signalling means.
Claim 5
Dependent Claim
20 words
An alarm system as specified in claim 3, wherein said selected non-passenger compartment is the luggage compartment of said vehicle.
Claim 6
Dependent Claim
17 words
Apparatus as specified in claim 1, wherein said means for supplying an electrical voltage comprise a battery.
Claim 7
Dependent Claim
14 words
Apparatus as specified in claim 1 wherein said time delay comprises a thermal relay.
Claim 8
Dependent Claim
36 words
Apparatus as specified in claim 1, usable in a vehicle having a battery, wherein said means for supplying an electrical voltage comprises an alarm battery, which is provided in addition to the battery of said vehicle.
Claim 9
Dependent Claim
22 words
Apparatus as specified in claim 7 wherein there is additionally included means for recharging said alarm battery during operation of said vehicle.
