Abstract
Abstract A safety closure device to prevent access by young children to appliances such as refrigerators, freezers, dishwashers and ovens. The safety closure device comprises a mounting means to secure the device to the appliance without damaging said appliance, a blocking means that alternately allows and prevents the door of the appliance from opening, a retention means that holds said blocking means in place and a releasing means that allows the release of said retention means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A safety closure device to prevent young children from independently gaining access into an appliance through a door of said appliance comprising: a rigid blocking arm for alternately allowing and blocking the opening of said appliance door; a rigid mounting plate pivotally connected to said blocking arm; mounting means connected to said mounting plate for removably attaching said safety closure device to said appliance; and a retention bar for alternately allowing and preventing the movement of said blocking arm from a blocking position to an open position, said retention bar being movably attached to said mounting plate and positioned so as to be alternately adjacent to and removed from said blocking arm: a retention bar housing attached to said mounting plate, said retention.
Claim 2
Dependent Claim
123 words
A safety closure device to prevent young children from independently gaining access into an appliance through a door of said appliance comprising: a rigid blocking arm for alternately allowing and blocking the opening of said appliance door; a rigid mounting plate pivotally connected to said blocking arm; mounting means connected to said mounting plate for removably attaching said safety closure device to said appliance; and a retention bar for alternately allowing and preventing the movement of said blocking arm from a blocking position to an open position, said retention bar being movably attached to said mounting plate and positioned so as to be alternately adjacent to and removed from said blocking arm: a retention bar housing attached to said mounting plate, said retention.
Claim 3
Dependent Claim
156 words
The invention of claim 1 further comprising: a retention bar housing attached to said mounting plate, said retention bar housing having an end that defines an aperture that allows said retention bar to be retracted into said retention bar housing so as to remove said retention bar from a position adjacent said blocking arm and to thereby allow said blocking arm to be moved, said retention bar housing further having a top surface that defines a circular aperture; and spring-mounted push button attached to said retention bar so as to protrude through said circular aperture in said top surface of said retention bar housing when said retention bar is fully extended adjacent to and parallel with said blocking arm, and prevent said retention bar from being moved from a position adjacent to said blocking arm to a position removed from said blocking arm until said push button is depressed through and removed from said circular aperture.
Claim 4
Dependent Claim
261 words
A safety closure device to prevent young children from independently gaining access into an appliance through a door of said appliance comprising: a rigid blocking arm for alternately allowing and blocking the opening of said appliance door; a rigid mounting plate pivotally connected to said blocking arm; mounting means connected to said mounting plate for removably attaching said safety closure device to said appliance; a retention bar for alternately allowing and preventing the movement of said blocking arm from a blocking position to an open position, said retention bar being movably attached to said mounting plate and positioned so as to be alternately adjacent to and removed from said blocking arm; a retention bar housing attached to said mounting plate, said retention bar housing having an end that defines an aperture that allows said retention bar to be retracted into said retention bar housing so as to remove said retention bar from a position adjacent said blocking arm and to thereby allow said blocking arm to be moved, said retention bar housing further having a top surface that defines a circular aperture; and a spring-mounted push button attached to said retention bar so as to protrude through said circular aperture in said top surface of said retention bar housing when said retention bar is fully extended adjacent to and parallel with said blocking arm, and prevent said retention bar from being moved from a position adjacent to said blocking arm to a position removed from said blocking arm until said push button is depressed through and removed from said circular aperture.
Claim 5
Dependent Claim
