Abstract
Abstract A vehicle ignition switch lock device comprising a cover member of rectangular box-like shape which will fit over the ignition lock on the steering column of a vehicle and having as part of the cover member a cylindrical heavy stainless steel cylinder which completely covers and surrounds the vehicle ignition switch. Two leg portions on the box-like member extend past the steering column and receive on the other side thereof a solid steel bar through appropriate apertures provided in the leg members. One of the leg members has a covered steel cylinder member which contains a cylindrical lock with arm member for engagement with an one end of the steel bar through a slot therein. The entire device preferably is made of saw and drill resistant stainless steel material and the cylindrical lock is of the pickproof type. The cylindrical lock is designed so that the key is non-removable from same except when the lock is in the locked position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
302 words
A vehicle ignition switch lock device installable about the vehicle steering column in surmounting relation to an ignition switch mounted on said steering column, the device comprising: a solid-walled housing member adapted to fit against a side portion of the steering column, the housing member having an opening disposed in at least a portion of one side thereof, the opening receiving the ignition switch therewithin to substantially cover the ignition switch; a pair of leg members extending from the housing member on opposite sides of the opening therein, the leg members being tangentially contiguous to the steering column and being of a length greater than the diameter of said steering column, free ends of the leg members lying in spaced opposed relation to each other beyond the edges of the column when the device is mounted on said column, the free ends of the leg members each having an elongated aperture formed therein; a bar member, the bar member being received within the apertures in the free ends of the leg members, the bar member, the leg members, and the body of the housing member essentially circumscribing the steering column, the bar member further having an elongated slot formed in one end thereof; lock means having a positionally displaceable latch member and carried on one of the leg members, the latch member being engageable within the slot in the bar member to lock the bar member to the leg members, thereby to lock the device onto the steering column; and a shielding member disposed within the housing member and attached to an inner wall thereof, the longitudinal axis of the shielding member being perpendicular to the longitudinal axis of the steering column when the device is mounted on said column, the ingition switch being thereby enclosed and covered by the shield member.
Claim 2
Dependent Claim
302 words
A vehicle ignition switch lock device installable about the vehicle steering column in surmounting relation to an ignition switch mounted on said steering column, the device comprising: a solid-walled housing member adapted to fit against a side portion of the steering column, the housing member having an opening disposed in at least a portion of one side thereof, the opening receiving the ignition switch therewithin to substantially cover the ignition switch; a pair of leg members extending from the housing member on opposite sides of the opening therein, the leg members being tangentially contiguous to the steering column and being of a length greater than the diameter of said steering column, free ends of the leg members lying in spaced opposed relation to each other beyond the edges of the column when the device is mounted on said column, the free ends of the leg members each having an elongated aperture formed therein; a bar member, the bar member being received within the apertures in the free ends of the leg members, the bar member, the leg members, and the body of the housing member essentially circumscribing the steering column, the bar member further having an elongated slot formed in one end thereof; lock means having a positionally displaceable latch member and carried on one of the leg members, the latch member being engageable within the slot in the bar member to lock the bar member to the leg members, thereby to lock the device onto the steering column; and a shielding member disposed within the housing member and attached to an inner wall thereof, the longitudinal axis of the shielding member being perpendicular to the longitudinal axis of the steering column when the device is mounted on said column, the ingition switch being thereby enclosed and covered by the shield member.
Claim 3
Dependent Claim
39 words
The structure set forth in claim 1, wherein the exposed edges of the extending leg members are covered with resilient edge material in order to prevent scratching and damage to the vehicle steering column as the device is installed.
Claim 4
Dependent Claim
31 words
The structure set forth in claim 2, together with a resilient gasket strip for protecting the side of the steering column adjacent to the bar member when the device is installed.
Claim 5
Dependent Claim
25 words
The structure set forth in claim 3, wherein the entire device is made of stainless steel material for extra resistance against unauthorized opening of same.
Claim 6
Dependent Claim
46 words
The structure set forth in claim 4, wherein the lock means comprises a key operated cylindrical lock and the key for the cylindrical lock is only removable when the cylindrical lock is in locked position to prevent loss of the key when the device is unlocked.
Claim 7
Dependent Claim
80 words
The device of claim 1 and further comprising a hollow shield housing attached to one of the leg members in surmounting relation to the aperture formed in said one leg member, the lock means being mounted in said shield housing, the shield housing enclosing at least major portions of the lock means including the latch member, the lock means being thereby spaced from said one leg member and disposed in spaced relation to the aperture in said one leg member.
Claim 8
Dependent Claim
49 words
The device of claim 1 wherein the bar member has a pin mounted on the end thereof opposite the end having the slot formed therein, the pin preventing passage through the aperture in the leg members of that end of the bar member in which said pin is disposed.
Claim 9
Dependent Claim
14 words
The device of claim 1 wherein the leg members are parallel to each other.
Claim 10
Dependent Claim
11 words
The device of claim 1 wherein the shielding member is cylindrical.
