Abstract

A shackleless padlock system is provided which includes a lock mechanism having a cylindrical body both protruding from one end thereof with a key-operating locking pin which retractably protrudes from the lock mechanism from a first to a second position for selectively engaging portions of a padlock body in order to either provide bolt engagement with the pad-lock body or for guiding a lock mechanism within the padlock body. Access to the locking pin in order that the lock mechanism may easily be removed and replaced with a different lock mechanism.

Claims

1. A shackleless padlock for locking hasp members, said shackleless padlock comprising:

a lock mechanism having a cylindrical body and a bolt protruding from one end thereof and key operated means, disposed within said cylindrical body for causing a spring biased locking pin to retractably protrude from said cylindrical body from a first protruding position to a second protruding position, and means, defining an opening in another end of said cylindrical body, for accepting a key and for providing access for the key to the key operated means;

a padlock body having front and back sides subtending a connecting surface, means defining a slotted recess in the back side, for receiving a hasp member, means, defining a cylindrical bore through said connection surface intersecting said slotted recess, for receiving said lock mechanism cylindrical body and means, defining a second bore in the padlock body aligned with the cylindrical bore and intersecting said slotted recess, for receiving said bolt;

means, defining a pin recess in the padlock body intersecting the cylindrical bore, for receiving the locking pin in the second protruding position in order to lock the lock mechanism with the padlock body with the bolt in the second bore;

means, defining a slot in the cylindrical bore, for receiving the locking pin in the first protruding position in order to align the locking pin with the pin recess and prevent removal of the lock mechanism from the padlock body; and

means, defining openings in the padlock body back side, for enabling depression of the spring biased locking pin into the lock mechanism cylindrical body in order to remove the lock mechanism from the padlock body when the locking pin is received in the pin recess and when the locking pin is received in the cylindrical bore slot.

2. The shackleless padlock according to claim 1 wherein said spring biased locking pin protrudes at a right angle with respect to the cylindrical body.

3. The shackleless padlock according to claim 2 wherein said spring biased locking pin comprises means, defining a ramp surface on a protruding end thereof, for causing the locking pin to depress into the lock mechanism cylindrical body as the cylindrical body is inserted into the padlock body cylindrical bore.

4. The shackleless padlock according to claim 3 wherein the slot in the padlock body cylindrical bore intersects the pin recess.

5. The shackleless padlock according to claim 4 wherein the padlock body opening, enabling depression of the locking pin, intersects the slot at a spaced apart relationship with the pin recess.

6. The shackleless padlock according to claim 4 wherein the padlock body opening, enabling depression of the locking pin, intersects the pin recess.

7. A shackleless padlock system for locking hasp members, said shackleless padlock system comprising:

a plurality of lock mechanisms each having a cylindrical body and a bolt protruding from one end thereof and key operated means, disposed within each said cylindrical body for causing a spring biased locking pin to retractably protrude from each said cylindrical body from a first protruding position to a second protruding position, and means, defining an opening in another end of each said cylindrical body, for accepting a key and for providing access for the key to the key operated means, each one of said plurality of lock mechanisms being operable with a different key;

a padlock body having front and back sides subtending a connecting surface;

means, defining a slotted recess in the back side, for receiving a hasp member;

means, defining a cylindrical bore through said connecting surface intersecting said slotted recess, for receiving any one of said plurality of lock mechanism cylindrical body; and

means, defining a second bore in the padlock body aligned with the cylindrical bore and intersecting said slotted recess, for receiving said bolt;

means, defining a pin recess in the padlock body intersecting the cylindrical bore, for receiving the locking pin in the second protruding position in order to lock the lock mechanism within the padlock body with the bolt in the second bore;

means, defining a slot in the cylindrical bore, for receiving the locking pin in the first protruding position in order to align the locking pin with the pin recess and prevent removal of the lock mechanism from the padlock body; and

means, defining openings in the padlock body back side, for enabling depression of the spring biased locking pin into the lock mechanism cylindrical body in order to remove one of said plurality of lock mechanisms from the padlock body and replace same with another of said plurality of lock mechanisms, said openings enabling depression of the locking pin when the locking pin is received in the pin recess and when the locking pin is received in the cylindrical bore slot.

8. The shackleless padlock system according to claim 7 wherein said spring biased locking pin of each of said plurality of lock mechanisms protrudes at a right angle with respect to the cylindrical body of each of said plurality of lock mechanisms.

9. The shackleless padlock system according to claim 8 wherein said spring biased locking pin of each of said plurality of lock mechanisms comprises means, defining a ramp surface on a protruding end thereof, for causing the locking pin to depress into the lock mechanism cylindrical body as the cylindrical body is inserted into the padlock body cylindrical bore.

10. The shackleless padlock system according to claim 9 wherein the slot in the padlock body cylindrical bore intersects with the pin recess.

11. The shackleless padlock system according to claim 10 wherein the padlock body opening, enabling depression of the locking pin, intersects the slot at a spaced apart relationship with the pin recess.

12. The shackleless padlock system according to claim 10 wherein the padlock body opening, enabling depression of the locking pin, intersects the pin recess.
