Abstract
Abstract A cabinet which is extremely difficult for a child to open comprising a substantially rectangular box having a downwardly opening hinged front, the longest dimension of said box is substantially transverse and designed to be greater than the normal arm length of a five-year old child, the front latched in place by first and second gravity latches, the first latch movable to the non-latching position through the use of a first pivotal bar with operation of the first pivotal bar being through an opening in the left side of the cabinet, the second latch movable to the non-latching position through the use of a second pivotal bar with operation of the second pivotal bar being through an opening in the right side of the cabinet, each of the first and second latches are interiorly spaced from their respective sides a distance to prevent actuation by a child, both the first and second latches must be in the non-latched position to permit opening of the cabinet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A medicine cabinet comprising: a substantially rectangular unit composed of at least a top, a front, a left side, a right side and a bottom, said front hingedly connected to said bottom; a first and second latch secured to said top, said latches movable independently of each other, each of said latches movable by gravity to a latched position, each of said latches cooperating with a latch pin mounted upon said front when located in said latched position; and a first actuating bar for said first latch capable of moving said first latch to an unlatched position, a second actuating bar for said second latch capable of moving said second latch to an unlatched position, said first actuating bar operable from adjacent said left side, said second actuating bar operable from adjacent said right side, both of said latches must be moved simultaneously to said unlatched position to effect pivoting of said front with respect to said bottom.
Claim 2
Dependent Claim
158 words
A medicine cabinet comprising: a substantially rectangular unit composed of at least a top, a front, a left side, a right side and a bottom, said front hingedly connected to said bottom; a first and second latch secured to said top, said latches movable independently of each other, each of said latches movable by gravity to a latched position, each of said latches cooperating with a latch pin mounted upon said front when located in said latched position; and a first actuating bar for said first latch capable of moving said first latch to an unlatched position, a second actuating bar for said second latch capable of moving said second latch to an unlatched position, said first actuating bar operable from adjacent said left side, said second actuating bar operable from adjacent said right side, both of said latches must be moved simultaneously to said unlatched position to effect pivoting of said front with respect to said bottom.
Claim 3
Dependent Claim
39 words
An apparatus as defined in claim 1 wherein: the transverse distance between said left side and said right side being substantially 36 inches whereby such length is normally greater than the spread arm distance of a 5-year old child.
Claim 4
Dependent Claim
74 words
An apparatus as defined in claim 1 wherein: said first actuating bar having a first handle facilitating movement by a human finger, said second actuating bar having a second handle facilitating movement by a human finger, said first handle spaced inwardly of said left side and operable through a first opening in said left side, said second handle spaced inwardly of said right side and operable through a second opening in said right side.
Claim 5
Dependent Claim
72 words
An apparatus as defined in claim 3 wherein: said spacing of said first handle from said left side and said spacing of said second handle from said right side is approximately 2 inches, whereby the length of an adult finger is sufficient for actuation of said first and second bars but normally the finger length of a 5-year old child is not sufficient to cause actuation of said first and second bars.
Claim 6
Dependent Claim
44 words
An apparatus as defined in claim 3 wherein: said first and second actuating bars are fulcrumed for pivotal movement intermediate their length, said fulcrum point of each of said first and second bars is located approximately one-third the bar length from its respective handle.
Claim 7
Dependent Claim
36 words
An apparatus as defined in claim 1 wherein: a plurality of ball latches located to cooperate between said top and a portion of said front when said first and second latches are in said latched position.
