Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
In an anti-theft device having a lock including key-operated means, a bolt adapted to engage a control element of an automotive vehicle with a Diesel engine and with mechanical engine starting means, said lock including key-operated means having a first position in Which the bolt is engaged with the control element and a second position in which the bolt is disengaged from said control element, and blocking means adapted to block the movement of said key-operating means, the improvement consisting in that said device comprises means for operatively connecting said blocking means to said engine starting means, said connecting means being responsive to the engine starting position of said engine starting means to block the movement of said key-operated means from said second into said first position, and responsive to the non-starting position of said engine starting means to permit movement of said key-operated means between said two positions.
Claim 2
Dependent Claim
149 words
In an anti-theft device having a lock including key-operated means, a bolt adapted to engage a control element of an automotive vehicle with a Diesel engine and with mechanical engine starting means, said lock including key-operated means having a first position in Which the bolt is engaged with the control element and a second position in which the bolt is disengaged from said control element, and blocking means adapted to block the movement of said key-operating means, the improvement consisting in that said device comprises means for operatively connecting said blocking means to said engine starting means, said connecting means being responsive to the engine starting position of said engine starting means to block the movement of said key-operated means from said second into said first position, and responsive to the non-starting position of said engine starting means to permit movement of said key-operated means between said two positions.
Claim 3
Dependent Claim
149 words
In an anti-theft device having a lock including key-operated means, a bolt adapted to engage a control element of an automotive vehicle with a Diesel engine and with mechanical engine starting means, said lock including key-operated means having a first position in Which the bolt is engaged with the control element and a second position in which the bolt is disengaged from said control element, and blocking means adapted to block the movement of said key-operating means, the improvement consisting in that said device comprises means for operatively connecting said blocking means to said engine starting means, said connecting means being responsive to the engine starting position of said engine starting means to block the movement of said key-operated means from said second into said first position, and responsive to the non-starting position of said engine starting means to permit movement of said keyoperated means between said two positions.
Claim 4
Dependent Claim
149 words
In an anti-theft device having a lock including key-operated means, a bolt adapted to engage a control element of an automotive vehicle with a Diesel engine and with mechanical engine starting means, said lock including key-operated means having a first position in Which the bolt is engaged with the control element and a second position in which the bolt is disengaged from said control element, and blocking means adapted to block the movement of said key-operating means, the improvement consisting in that said device comprises means for operatively connecting said blocking means to said engine starting means, said connecting means being responsive to the engine starting position of said engine starting means to block the movement of said key-operated means from said second into said first position, and responsive to the non-starting position of said engine starting means to permit movement of said keyoperated means between said two positions.
Claim 5
Dependent Claim
96 words
Anti-theft device according to claim 1, wherein said blocking means are constituted of an electromagnet and a movable core and said connecting means comprises a first switch movable in response to the engine starting position of said starting means to a first position in which it is placed in an electrical circuit carrying the operating current for said vehicle and including a second switch operatively coupled to said key-operated means, and in response to the non-engine starting position of said starting means to a second position in which it closes the energizing circuit of said electromagnet.
Claim 6
Dependent Claim
38 words
Anti-theft device according to claim 2 for an automotive vehicle with a Diesel engine including injection pump means controllable by a control lever, wherein said engine starting means comprises said control lever operatively associated with said first switch.
Claim 7
Dependent Claim
38 words
Anti-theft device according to claim 2 for an automotive vehicle with a Diesel engine including pressure releasing means controllable by a control lever, wherein said engine starting means comprises said control lever operatively associated with said first switch.
