Tamper-resistant lock
First Claim
1. A locking system, comprising:
- a tamper-resistant lock, comprising;
a cylindrical lock body having external threading on at least a portion of a length of the cylindrical lock body;
a bore extending into an end of the cylindrical lock body, the bore having an engagement feature disposed on a wall defining the bore, the engagement feature being disposed a particular distance away from an opening of the bore; and
a bore cap sized and shaped to fit within and occlude the opening of the bore, the bore cap comprising an arcuate head having a flat, continuously smooth top surface and a beveled edge,wherein at least the arcuate head of the bore cap is made of a ferrous material; and
a key operable for use with the tamper-resistant lock, comprising;
a collar having a cylindrical key body sized and shaped to be at least partially disposed within the bore;
an opening defined by a sidewall of the collar;
a retractable engagement member at least partially disposed within the opening defined by the sidewall of the collar;
a spring disposed within the collar;
a plunger extending from a proximal end to a distal end, the distal end disposed within the collar and interfacing with the spring and having a recess that is sized and shaped to accommodate the retractable engagement member; and
a magnet disposed at the proximal end of the plunger and operable to engage the arcuate head of the bore cap such that a magnetic force between the magnet and the arcuate head of the bore cap is greater than a resistive force retaining the bore cap in association with the cylindrical lock body.

Abstract
A locking system includes a tamper-resistant lock and key. The tamper-resistant lock includes a cylindrical lock body with external threading on at least a portion thereof and a bore extending into an end of the cylindrical lock body. The bore includes an engagement feature disposed on the wall that defines the bore, and the engagement feature is disposed a particular distance away from the bore opening. The key includes a collar that has a cylindrical key body that fits within the bore of the cylindrical lock body. The cylindrical key body also includes an opening defined by the collar sidewall, a retractable engagement member at least partially disposed within the opening, a spring disposed within the collar, and a plunger disposed within the collar that is operable to engage the spring and has a recess sized and shaped to accommodate the retractable engagement member.

14. A locking system, comprising:
-
a housing comprising an anchoring member and a lid; a tamper-resistant lock for securing the lid to the anchoring member, the tamper-resistant lock comprising; a cylindrical lock body having external threading on at least a portion of a length of the cylindrical lock body, wherein the portion of the cylindrical lock body passes through the lid and is selectively received within the anchoring member; and a bore extending into an end of the cylindrical lock body, the bore having an engagement feature disposed on a wall defining the bore, the engagement feature being disposed a particular distance away from an opening of the bore; and a bore cap sized and shaped to fit within and occlude the opening of the bore, the bore cap comprising an arcuate head having a flat, continuously smooth top surface and a beveled edge, wherein the beveled edge is recessed below a surface of the lid, and wherein at least the arcuate head of the bore cap is made of a ferrous material; and a key, comprising; a collar having a cylindrical key body sized and shaped to be at least partially disposed within the bore; an opening defined by a sidewall of the collar; a retractable engagement member at least partially disposed within the opening; a spring disposed within the collar; a plunger extending from a proximal end to a distal end, the distal end disposed within the collar and interfacing with the spring and having a recess that is sized and shaped to accommodate the retractable engagement member; and a magnet disposed at the proximal end of the plunger and operable to engage the arcuate head of the bore cap such that a magnetic force between the magnet and the arcuate head of the bore cap is greater than a resistive force retaining the bore cap in association with the cylindrical lock body. - View Dependent Claims (15, 16, 17, 18, 19)
