US 5,472,247 A · Multi-point high security locking mechanism for lottery machines

Abstract

A locking mechanism which provides a number of resistance points, all of which function to impede the opening of a door located on the chassis of a lottery dispensing machine or any other enclosure that must be secured. The locking mechanism includes a rotating cam which sets the lock in motion. Rotation of the cam is translated into reciprocating motion of a number of bolts which move into a locked position. Once the bolts are in a fully locked position, movement of the door is impeded. If two bolts are used, they face in opposite directions. If more than two bolts are used, they all face in different directions. This makes the lock impossible to jimmy. Further, to successfully pry open the lock would require an effort great enough to cause substantial structural damage to the enclosure itself. A cam extension is also provided which provides extra resistance when the locking mechanism is in a closed position.

Dependent claims

A locking mechanism for an enclosure having an access opening, the locking mechanism comprising:

A) a door, hinged to the enclosure, for covering the access opening;
B) a cam, rotatably attached to the door and having an extension;
C) a first link member pivotally attached to the extension of the cam;
D) a first cylindrical bolt pivotally attached to the first link member;
E) a first receptacle, attached to the enclosure, the first receptacle having a first cylindrical bore;
F) the first bolt aligned with the first cylindrical bore;
G) a second receptacle attached to the enclosure, the second receptacle having a second cylindrical bore oriented substantially perpendicular to the first cylindrical bore;
H) a second bolt, slidingly connected to the door and aligned with the second cylindrical bore;
and
I) a first motion translator attached to the first bolt;
J) the first link member providing a means for translating rotational movement of the cam into reciprocating movement of the first bolt such that the first bolt enters the first cylindrical bore and such that the first motion translator pushes the second bolt into the second cylindrical bore.

A locking mechanism for an enclosure, comprising:

A) a door, pivotally connected to the enclosure;
B) a cam, rotatably connected to the door;
C) a first lock assembly, pivotally attached to the cam at a fixed end and slidingly attached to the door at a free end, the first lock assembly comprising a first motion translator;
D) a second lock assembly, slidingly attached to the door and oriented substantially perpendicular to the first lock assembly, the second lock assembly having a first contact region and an insertion end;
E) a first receptacle, attached to the enclosure and having a first cylindrical bore;
and
F) a second receptacle, attached to the enclosure and having a second cylindrical bore oriented substantially perpendicular to the first cylindrical bore;
G) the first lock assembly being aligned such that motion of the cam pushes the free end of the first lock assembly into the first cylindrical bore;
and
H) the first motion translator being located such that motion of the first lock assembly causes the first motion translator to push the insertion end of the second lock assembly into the second cylindrical bore.
