Locking device with passage
View Patent ↗A lock device for use with a key is disclosed. The lock device includes a locking spindle including a plurality of locking spindle bores and a passage extending axially along an axial length of the locking spindle, and a driver structure including a plurality of driver structure bores. An interface between the driver structure and the locking spindle forms a shear line. The lock device also includes a plurality of combination pins in the plurality of locking spindle bores, and a plurality of driver pins in the driver structure bores in the driver structure, the plurality of driver pins being respectively associated with the plurality of combination pins.
1. A lock device for use with a key with an extended portion, the lock device comprising:
a locking spindle including a plurality of locking spindle bores and a passage extending axially along an axial length of the locking spindle;
a driver structure including a plurality of driver structure bores, wherein an interface between the driver structure and the locking spindle forms a shear line;
a locking member coupled to a distal end of the locking spindle;
a plurality of combination pins in the plurality of locking spindle bores; and
a plurality of driver pins in the driver structure bores in the driver structure, the plurality of driver pins being respectively associated with the plurality of combination pins,
wherein the passage extends to the shear line and the extended portion of the key extends to the shear line when the key is used to turn the locking spindle.
2. The lock device of claim 1 wherein the extended portion is configured to temporarily provide a solid surface for the locking spindle at the shear line, when the key is used to turn the locking spindle.
3. The lock device of claim 1 wherein the lock device is a cylinder lock.
4. The lock device of claim 1 wherein the locking member is in the form of a T-bar.
5. The lock apparatus of claim 1 wherein the extended portion is configured to keep a driver pin from entering the passage when the key is used to turn the locking spindle.
6. The lock device of claim 1 wherein the passage coincides with an alignment tab region of the lock device.
7. The lock device of claim 1 further comprising a plurality of springs in the driver structure bores in the driver structure.
8. A locking apparatus comprising:
the lock device of claim 1 ; and
a key comprising a handle, an extended portion, and a coded portion between the handle and the extended portion,
wherein the extended portion extends to the shear line when the key is used to lock or unlock the lock device.
9. The locking apparatus of claim 8 wherein the coded portion is circular.
10. The locking apparatus of claim 8 wherein the lock device further comprises a housing disposed around the locking spindle and the driver structure, and a pair of parallel pins coupled to the housing.
11. A security system comprising
the locking apparatus of claim 8 ; and
a portable electronic device, wherein the locking apparatus is used to secure the portable electronic device to an object other than the locking apparatus.
12. A locking apparatus comprising:
a lock device comprising a locking spindle including a plurality of locking spindle bores and a passage extending axially along an axial length of the locking spindle, a locking member coupled to a distal end of the locking spindle, a driver structure including a plurality of driver structure bores, wherein an interface between the driver structure and the locking spindle forms a shear line and the passage extends through the locking spindle to the shear line, a plurality of combination pins in the plurality of locking spindle bores, and a plurality of driver pins in the driver structure bores in the driver structure, the plurality of driver pins being respectively associated with the plurality of combination pins, further wherein the passage does not contain a combination pin; and
a key including a coded portion and an extended portion, wherein the extended portion is configured to fit in the passage and extend to about the shear line.
13. The locking apparatus of claim 12 wherein the lock device further comprises a housing disposed around the locking spindle and the driver structure.
14. The locking apparatus of claim 12 wherein the extended portion is configured to temporarily provide a solid surface for the locking spindle at the shear line, when the key is used to turn the locking spindle.
15. A method for using a lock device, the method comprising:
inserting a key into a keyway of a lock device, wherein the key includes an extended portion that passes through a passage in a locking spindle in the lock device and to a shear line between the locking spindle and a driver structure, wherein the extended portion serves to temporarily provide a solid surface for the locking spindle at the shear line while the key is inserted into the keyway;
turning the key; and
attaching the lock device to a portable electronic device.
16. The method of claim 15 wherein the lock device is a cylinder lock.
17. The method of claim 15 wherein the passage is an open passage.
18. The method of claim 15 wherein the passage does not contain a combination pin.
