Abstract

A padlock for adjusting to a length of a lock cylinder includes a padlock housing and a shackle having an unlocked position and a locked position within the padlock housing. A central bore is disposed in a bottom of the padlock housing having a depth longer than the length of the lock cylinder for accepting the lock cylinder within the padlock housing. An adaptable cam is adjustably joinable to a distal end of the lock cylinder for adjusting for a difference between the depth and the length, and for rotatable engagement of the shackle to enable the shackle to move between the locked position and the unlocked position. A lock cap is joinable to an open end of the central bore for retaining the adaptable cam and the lock cylinder within the central bore.

Claims

1. A padlock for adjusting to a varying length of a lock cylinder, the padlock comprising:

a padlock housing;

a shackle having an unlocked position and a locked position within said padlock housing;

means for accepting the lock cylinder within a depth of said padlock housing;

means for adjusting for the varying length being adjustably joinable at a plurality of positions along a length of a distal end of the lock cylinder, and for rotatable engagement of said shackle to enable said shackle to move between said locked position and said unlocked position; and

means for retaining said adjusting means and the lock cylinder within said depth by contacting a beveled surface of the lock cylinder.

2. The padlock as recited in claim 1, further comprising means for securing the lock cylinder within said depth by contacting an outside surface of the lock cylinder with flat ends.

3. The padlock as recited in claim 2, further comprising means for inhibiting removal of said securing means.

4. The padlock as recited in claim 1, further comprising means for engaging said retaining means to prevent said retaining means from being removed.

5. The padlock as recited in claim 1, further comprising means insertable within said central bore and surrounding a portion of a housing of the lock cylinder for further additionally adjusting for the varying length.

6. A padlock for adjusting to a varying length of a lock cylinder, the padlock comprising:

a padlock housing;

a shackle having an unlocked position and a locked position within said padlock housing;

means for engaging said shackle to at least retain said shackle in said locked position;

a central bore disposed in a bottom of said padlock housing having a depth longer than the varying length of the lock cylinder for accepting the lock cylinder within said padlock housing;

an adaptable cam adjustably joinable at a plurality of positions along a length of a distal end of the lock cylinder for adjusting for the varying length, and for rotatable engagement of said engaging means to enable said shackle to move between said locked position and said unlocked position; and

a lock cap joinable to an open end of said central bore and comprising a beveled surface being configured for contacting a beveled surface of the lock cylinder for retaining said adaptable cam and the lock cylinder within said central bore.

7. The padlock as recited in claim 6, further comprising a first set screw entering said central bore from a first side of said padlock housing and an opposing second set screw entering said central bore from a second side of said padlock housing for securing the lock cylinder within said central bore, said first set screw and said second set screw each comprising a flat end being configured to contact an outside surface of the lock cylinder.

8. The padlock as recited in claim 7, further comprising a roller pin being orthogonally oriented to said first set screw for inhibiting rotation of said first set screw.

9. The padlock as recited in claim 8, further comprising a third set screw entering from a top of said padlock housing for retaining said roller pin within said padlock housing.

10. The padlock as recited in claim 7, wherein said shackle in said locked position inhibits rotation of said second set screw.

11. The padlock as recited in claim 8, further comprising a fourth set screw entering said central bore from said first side for engaging said lock cap to prevent said lock cap from being removed, wherein rotation of said fourth set screw is inhibited by said roller pin.

12. The padlock as recited in claim 6, further comprising a lock spacer insertable within said central bore and surrounding a portion of a housing of the lock cylinder for further additionally adjusting for the varying length.

13. The padlock as recited in claim 6, wherein said shackle further comprises at least one groove for engagement with said engaging means.

14. The padlock as recited in claim 13, wherein said adaptable cam further comprises at least one groove for engagement with said engaging means.

15. The padlock as recited in claim 11, further comprising a plurality of caps for covering distal ends of set screws facing away from said central bore.

16. A padlock for adjusting to a varying length of a lock cylinder, the padlock comprising:

a padlock housing comprising a central bore disposed in a bottom having a depth longer than the varying length of the lock cylinder for accepting the lock cylinder, and at least two bores in a top extending about opposing sides of said central bore;

a generally u-shaped shackle disposable within said at least two bores and having an unlocked position and a locked position within said padlock housing;

means for engaging said shackle to at least retain said shackle in said locked position;

an adaptable cam adjustably joinable at a plurality of positions along a length of a tenon on a distal end of the lock cylinder for adjusting for the varying length by joining at a one of said positions, and for rotatable engagement of said engaging means to enable said shackle to move between said locked position and said unlocked position;

a first set screw entering said central bore from a first side of said padlock housing;

a second set screw, opposing said first set screw, entering said central bore from a second side of said padlock housing, wherein said first set screw and said second set screw each comprise a flat end being configured to contact an outside surface of the lock cylinder and are operable for securing the lock cylinder within said central bore, and wherein said shackle in said locked position inhibits rotation of said second set screw;

a roller pin being orthogonally oriented to said first set screw and parallel to said central bore for inhibiting rotation of said first set screw;

a third set screw entering from a one of said at least two bore holes for retaining said roller pin within said padlock housing;

a lock cap joinable to an open end of said central bore and comprising a beveled surface being configured for contacting a beveled surface of the lock cylinder for retaining said adaptable cam and the lock cylinder within said central bore; and

a fourth set screw entering said central bore from said first side for engaging said lock cap to prevent said lock cap from being removed, wherein rotation of said fourth set screw is inhibited by said roller pin.

17. The padlock as recited in claim 16, further comprising a lock spacer insertable within said central bore and surrounding a portion of a housing of the lock cylinder for further additionally adjusting for the varying length.

18. The padlock as recited in claim 16, wherein said shackle further comprises at least one groove for engagement with said engaging means.

19. The padlock as recited in claim 18, wherein said adaptable cam further comprises at least one groove for engagement with said engaging means.

20. The padlock as recited in claim 16, further comprising a plurality of caps for covering distal ends of set screws facing away from said central bore.
