Abstract

A lock having a body, an engaging element having a first end, a locking mechanism for securing the first end to the body, the locking mechanism adapted to selectively conceal or reveal a passage in the body, through translation of a sliding gate, through which the first end may move to unlock the lock; the engaging element has a second end which is retained by the body at all times but is free to rotate. In other aspects, a lock has a body, a shackle having heel and toe portions, the heel portion engaged within the body, and a gate mechanism for selectively concealing or revealing a passage in the body from which the toe portion may move to unlock the lock, wherein movement of the toe portion is achieved through rotation of the toe about the heel.

Claims

1. A lock comprising:

a body having a cutout through a side portion;

an outer shell partially surrounding said body;

a shackle, said shackle having a first end affixed to said body such that said first end is capable of rotation, and said shackle having a second end adapted to fit within said cutout;

wherein said outer shell is adapted to slide relative to said body between a first position concealing said cutout and a second position relative to said body revealing said cutout, said second end of said shackle being free to enter or leave said cutout when said outer shell is in said second position, movement of said outer shell being in a direction perpendicular to said shackle when said outer shell is moved between said first position and said second position.

2. The lock of claim 1, wherein said outer shell further comprises at least one mating element, said mating element adapted to associate with a tool to move said outer shell between said first position and said second position.

3. The lock of claim 2, wherein said at least one mating element comprises at least one aperture.

4. The lock of claim 1, wherein said lock further comprises a spring arranged in said body and adapted to bias said outer shell toward said first position.

5. The lock of claim 1, wherein said outer shell further comprises an elongated aperture through which said first end of said shackle extends.

6. The lock of claim 5, wherein said elongated aperture defines the limit of excursion of said outer shell relative to said body.

7. The lock of claim 6, wherein said outer shell further comprises an opening, said opening being flush with said body when said outer shell is in said first position.

8. The lock of claim 1, wherein said lock further comprises a locking mechanism, said locking mechanism selectively moveable between a lock position and an unlock position, said locking mechanism preventing rotation of said shackle when in said lock position and permitting rotation of said shackle about said first end when in said unlock position.

9. The lock of claim 8, wherein said locking mechanism is only capable of selectively moving between said lock position and said unlock position when said outer shell is in said second position.

10. The lock of claim 8, wherein said outer shell further comprises an aperture, said aperture being moved into registration with said locking mechanism when said outer shell is in said second position, and said outer shell covering said locking mechanism when said outer shell is in said first position.

11. A lock comprising:

a body having a cutout through a side portion;

an outer shell partially surrounding said body;

a shackle, said shackle having a first end affixed to said body such that said first end is capable of rotation, and said shackle having a second end adapted to fit within said cutout;

wherein said outer shell is adapted to slide relative to said body between a first position concealing said cutout and a second position relative to said body revealing said cutout, said second end of said shackle being free to enter or leave said cutout when said outer shell is in said second position;

said lock further comprising a spring arranged in said body and adapted to bias said outer shell toward said first position.

12. A lock comprising:

a body having a cutout through a side portion;

an outer shell partially surrounding said body;

a shackle, said shackle having a first end affixed to said body such that said first end is capable of rotation, and said shackle having a second end adapted to fit within said cutout;

wherein said outer shell is adapted to slide relative to said body between a first position concealing said cutout and a second position relative to said body revealing said cutout, said second end of said shackle being free to enter or leave said cutout when said outer shell is in said second position;

wherein said outer shell further comprises an elongated aperture through which said first end of said shackle extends, said elongated aperture defining the limit of excursion of said outer shell relative to said body.

13. The lock of claim 12, wherein said outer shell further comprises an opening, said opening being flush with said body when said outer shell is in said first position.

14. A lock comprising:

a body having a cutout through a side portion;

an outer shell partially surrounding said body;

a shackle, said shackle having a first end affixed to said body such that said first end is capable of rotation, and said shackle having a second end adapted to fit within said cutout;

wherein said outer shell is adapted to slide relative to said body between a first position concealing said cutout and a second position relative to said body revealing said cutout, said second end of said shackle being free to enter or leave said cutout when said outer shell is in said second position;

said lock further comprising a locking mechanism, said locking mechanism selectively moveable between a lock position and an unlock position, said locking mechanism preventing rotation of said shackle when in said lock position and permitting rotation of said shackle about said first end when in said unlock position, said locking mechanism being only capable of selectively moving between said lock position and said unlock position when said outer shell is in said second position.

15. A lock comprising:

a body having a cutout through a side portion;

an outer shell partially surrounding said body;

a shackle, said shackle having a first end affixed to said body such that said first end is capable of rotation, and said shackle having a second end adapted to fit within said cutout;

wherein said outer shell is adapted to slide relative to said body between a first position concealing said cutout and a second position relative to said body revealing said cutout, said second end of said shackle being free to enter or leave said cutout when said outer shell is in said second position;

said lock further comprising a locking mechanism, said locking mechanism selectively moveable between a lock position and an unlock position, said locking mechanism preventing rotation of said shackle when in said lock position and permitting rotation of said shackle about said first end when in said unlock position, said outer shell further comprising an aperture, said aperture being moved into registration with said locking mechanism when said outer shell is in said second position, and said outer shell covering said locking mechanism when said outer shell is in said first position.
