Combination push button and/or key operated padlock
First Claim
1. A push button padlock comprising:
- a housing, a shackle mounted to said housing and movable between an open position in which said padlock in unlocked and a closed position in which said padlock is locked, a shackle detachment movable between a first position in which said shackle detachment engages an end of said shackle to prevent said shackle from moving from its closed position to its open position and a second position in which said shackle detachment is disengaged from said shackle to allow said shackle to move between said open and closed positions;
a push button slide plate for operatively connected to said shackle detachment;
a plurality of push buttons mounted to said housing for said push button slide plate, said push buttons being movable between a raised position and a pressed position;
at least one of said push buttons being constructed as releasing push button, the remainder of said push buttons being constructed as blocking push buttons;
said at least one releasing push button engaging said slide plate when said at least one releasing push button is in said raised position to prevent movement of said slide plate and hence prevent movement of said shackle detachment from said first position to said second position and being disengaged from said slide plate when in said pressed position to allow movement of said slide plate, and hence to permit movement of said shackle detachment from said first position to said second position;
said blocking push buttons being out of engagement said slide plate when said blocking push button is in said raised position to permit movement of said slide plate and hence permit movement of said shackle detachment from said first position to said second position and being engaged with said slide plate when in said pressed position to prevent movement of said slide plate, and hence to prevent movement of said shackle detachment from said first position to said second position;
whereby, said shackle detachment can be moved from said first position to said second position only when said at least one releasing push button is in said pressed position and all said blocking push buttons are in said raised position. said push buttons having independently mounted spring caps to assist in camouflaging the at least one releasing push button and the blocking push buttons from each other;

Abstract
A combination push button and/or key operated padlock is disclosed as having a housing, a shackle detachably connected to the housing for opening and closing the padlock, a push button slide plate for operative detachable movement of the shackle relative to the housing, and a plurality of push buttons mounted to the housing for the push button slide plate. At least one of the push buttons is a releasing push button that detach from the push button slide plate when depressed. The remainder of the push buttons are blocking push buttons that engage the push button slide plate when depressed. A shackle detachment is connected to the push button slide plate for moving it in detachable position when the releasing push buttons only are depressed. Each of the push buttons having independently mounted spring loaded end caps on each free end to assist in camouflaging the releasing and blocking push button from each other. In lieu of opening and closing the padlock with push buttons, a key operated lock may be used for this purpose.
