Abstract
A device used to secure an automobile catalytic converter. The invention deters a person from tampering with or stealing a catalytic converter. The device consists of at least four overlapping, and adjustable plates comprising an adjustable frame structure that clamp around the catalytic converter. Tightening of fasteners keeps the frame structure securely in position around the catalytic converter, preventing easy access to the catalytic converter. The frame structure is then secured to the automobile itself with a looped cable, which prevents easy removal of the catalytic converter.
Claims20
A catalytic converter theft deterrent device comprising:
- an adjustable frame structure having at least a top set and a bottom set of plates, each set comprising at least two plates having a fastening flange and a distal flange and at least two bends in the plate between the fastening flange and the distal flange such that a face of the fastening flange of the plate is parallel to a face of the distal flange of the plate, the fastening flange and distal flange each having at least one hole that receives a fastener;
- at least one vertical fastener passing through the at least one hole in the distal flange, the distal flange positioned to overlap a plate having multiple holes for width adjustment such that the at least one vertical fastener further passes through at least one of the multiple holes thereby fastening the overlapping distal flange to the plate having multiple holes;
- at least one vertical fastener passing through the at least one hole of each opposing top and bottom fastening flange connecting the top and bottom sets of plates such that the top and bottom sets of plates clamp around the catalytic converter;
- and
- at least one cable attached to the adjustable frame structure at two points, the at least one cable forming a loop that encircles at least a portion of at least one vehicle undercarriage element to secure the adjustable frame structure to a vehicle undercarriage.

A method of deterring the theft of a catalytic converter comprising the acts of:
- clamping an adjustable frame structure around the catalytic converter wherein the adjustable frame structure comprises at least a top set and a bottom set of plates, each set comprising at least two plates having a fastening flange and a distal flange and at least two bends in the plate between the fastening flange and the distal flange such that a face of the fastening flange of the plate is parallel to a face of the distal flange of the plate, the fastening flange and distal flange each having at least one hole that receives a fastener;
- positioning the distal flange to overlap a plate having multiple holes for width adjustment such that the at least one hole in the distal flange is aligned with at least one of the multiple holes;
- fastening the overlapping distal flange to the plate having multiple holes by passing at least one vertical fastener through the at least one hole in the distal flange and the at least one of the multiple holes in the plate with which the at least one hole in the distal flange is aligned;
- fastening the top and bottom sets of plates together by passing at least one vertical fastener through the at least one hole of each opposing top and bottom fastening flange such that the top and bottom sets of plates clamp around the catalytic converter;
- and
- securing the adjustable frame structure to a vehicle undercarriage by attaching at least one cable to the adjustable frame structure at two points such that the at least one cable forms a loop that encircles at least a portion of at least one vehicle undercarriage element.

- an adjustable frame structure having at least a top set and a bottom set of plates;
- each set comprising at least two plates having a fastening flange and a distal flange and at least two bends in the plate between the fastening flange and the distal flange such that a face of the fastening flange of the plate is parallel to a face of the distal flange of the plate the fastening flange and distal flange each having at least one hole that receives a fastener;
- wherein the plates with fastening and distal flanges have at least one bend in the plate located beyond the fastening flange and at the opposing end of the distal flange, the bend causing the plate to be substantially parallel to the vertical fastener and shielding at least one vertical fastener that passes through the at least one hole of each opposing top and bottom fastening flange connecting the top and bottom sets of plates such that the top and bottom sets of plates clamp around the catalytic converter;
- at least one vertical fastener passing through the at least one hole in the distal flange, the distal flange positioned to overlap a plate having multiple holes for width adjustment such that the at least one vertical fastener further passes through at least one of the multiple holes thereby fastening the overlapping distal flange to the plate having multiple holes;
- and
- at least one cable attached to the adjustable frame structure at two points, the at least one cable forming a loop that encircles at least a portion of at least one vehicle undercarriage element to secure the adjustable frame structure to a vehicle undercarriage.
