Abstract
Abstract A device for preventing the insertion of foreign objects into electrical outlets by infants and small children. The device is connected and secured to or replaces currently existing outlets. Internal blocking members are moved into the open position by depressing the locking buttons and sliding the blocking member away from the center of the device thus allowing electrical plugs to be inserted into the device. When a plug is removed from the device the corresponding blocking member is automatically forced into the closed position by internal springs. While in the closed position the openings for the plug are completely blocked preventing the insertion of objects into the openings and the locking buttons automatically engage in the locked position preventing movement of the blocking member until the locking buttons are depressed again.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
114 words
A child resistant electrical outlet which comprises: (a) a means for conducting electrical current from an existing electrical outlet to electrical appliance plugs while the plugs are inserted in the child resistant electrical outlet; (b) a means for securing to existing electrical outlets in such a manner to prevent easy removal by infants and children; (c) a blocking device to prevent insertion of objects into the child resistant electrical outlet while not in use; (d) a means for automatically closing the blocking device when the outlet is taken out of service; (e) a mechanism for automatically locking the blocking device in the closed position while the child resistant electrical outlet is not in service.
Claim 2
Dependent Claim
114 words
A child resistant electrical outlet which comprises: (a) a means for conducting electrical current from an existing electrical outlet to electrical appliance plugs while the plugs are inserted in the child resistant electrical outlet; (b) a means for securing to existing electrical outlets in such a manner to prevent easy removal by infants and children; (c) a blocking device to prevent insertion of objects into the child resistant electrical outlet while not in use; (d) a means for automatically closing the blocking device when the outlet is taken out of service; (e) a mechanism for automatically locking the blocking device in the closed position while the child resistant electrical outlet is not in service.
Claim 3
Dependent Claim
20 words
A child resistant electrical outlet as cited in claim 1 in which the blocking device comprises movable internal blocking members.
Claim 4
Dependent Claim
25 words
A child resistant electrical outlet as cited in claim 2 in which the locking mechanism is an integral part of the movable internal blocking member.
Claim 5
Dependent Claim
38 words
A child resistant electrical outlet as cited in claim 3 in which the means for automatically closing the blocking members comprises a spring or springs used to force the blocking members toward the closed position at all times.
Claim 6
Dependent Claim
32 words
A child resistant electrical outlet as cited in claim 4 in which the means for locking the blocking members in the closed position comprises two locking push buttons on each blocking member.
Claim 7
Dependent Claim
182 words
A child resistant electrical outlet as cited in claim 5 in which the locking push buttons comprise: (a) a spring mechanism to allow depression of the locking button when the blocking member is to be moved into the open position and to return the locking button to the undepressed position automatically when the blocking member returns to the closed position; (b) a wide section which protrudes through an enlarged opening in the outer shell of the child resistant electrical outlet when the blocking member is in the closed position therefore preventing any movement of the blocking member until the locking buttons are depressed; (c) a narrow section which aligns with a narrow slot in the outer shell of the child resistant electrical outlet when the locking button is depressed, allowing the blocking member to be moved to the open position when both buttons are depressed; (d) a head which protrudes through the outer shell of the child resistant electrical outlet at all times and is used to depress the locking buttons and move the blocking member to the open position when needed.
Claim 8
Dependent Claim
47 words
A child resistant electrical outlet as cited in claim 6 in which the means for securing to the existing outlet comprises a screw which is inserted through a screw hole in the child resistant electrical outlet and threaded into an existing hole in the existing electrical outlet.
Claim 9
Dependent Claim
102 words
An improved electrical outlet wherein the improvement comprises: (a) a blocking device to prevent the insertion of objects into the electrical outlet while not in use which comprises movable internal blocking members; and (b) a means for automatically closing the blocking device when the electrical outlet is taken out of service which comprises a spring or springs used to force the blocking members toward the closed position at all times; and (c) a mechanism, which is an integral part of the movable blocking members, for automatically locking the blocking device in the closed position while the electrical outlet is not in service.
Claim 10
Dependent Claim
102 words
An improved electrical outlet wherein the improvement comprises: (a) a blocking device to prevent the insertion of objects into the electrical outlet while not in use which comprises movable internal blocking members; and (b) a means for automatically closing the blocking device when the electrical outlet is taken out of service which comprises a spring or springs used to force the blocking members toward the closed position at all times; and (c) a mechanism, which is an integral part of the movable blocking members, for automatically locking the blocking device in the closed position while the electrical outlet is not in service.
Claim 11
Dependent Claim
30 words
An improved electrical outlet as cited in claim 8 in which the means for locking the blocking members in the closed position comprises two locking push-buttons on each blocking member.
Claim 12
Dependent Claim
184 words
An improved electrical outlet as cited in claim 9 in which the locking push button comprise: (a) a spring mechanism to allow depression of the locking push-button when the blocking member is to be moved into the open position and to return the locking push-button to the undepressed position automatically when the blocking member returns to the closed position; and (b) a wide section which protrudes through an enlarged opening in the outer shell of the improved electrical outlet when the blocking member is in the closed position therefore preventing any movement of the blocking member until the locking push-buttons are depressed; and (c) a narrow section which aligns with a narrow slot in the outer shell of the improved electrical outlet when the when the locking push-button is depressed, allowing the blocking member to be moved to the open position when both locking push-buttons are depressed; and (d) a head which protrudes through the outer shell of the improved electrical outlet at all times and is used to depress the locking buttons and move the blocking member to the open position as needed.
