## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. provisional application Ser. No. 60/782,943 filed Mar. 16, 2006.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lock assembly for selectively locking and unlocking a door using a key.
2. Description of the Prior Art
The lock assemblies of the prior art are typically used for locking a door or a window. An example of such a configuration for locking a door is shown in U.S. Patent Publication No. 2005/0011239 to Lurie, et al. The lock assembly disclosed in this publication has multiple parts specific to either a first lock configuration or a second lock configuration. Typically, the first lock configuration is commonly referred to as a mortise cylinder and the second lock configuration is commonly referred to as a rim cylinder. The mortise cylinder includes a first actuator and a first drive member coupled to each other such that rotation of the first drive member rotates the first actuator to lock and unlock the door. The rim cylinder includes a second actuator and a second drive member coupled to each other such that rotation of the second drive member rotates the second actuator to lock and unlock the door. Meaning, each of the mortise and rim cylinders require a different drive member to lock and unlock the door.
Another example of a lock assembly is shown in U.S. Pat. No. 4,444,033 to Deckert. The lock assembly disclosed in this patent includes a housing for mounting to a door. The lock assembly includes a drive member integral disposed on a plug for either a first lock configuration or a second lock configuration. Again, the first lock configuration is commonly referred to as a mortise cylinder and the second lock configuration is commonly referred to as a rim cylinder. The mortise cylinder includes a first actuator and the rim cylinder includes a second actuator. The first actuator is coupled to the drive member for the first lock configuration or the second actuator is coupled to the drive member in the second lock configuration independently from the first actuator. In either situation, since the drive member is integral with the plug, the housing must be removed from the door in order to remove the plug from the housing because the actuator coupled to the drive member cannot be pulled through the housing. Meaning, the first actuator or the second actuator must be detached from the drive member before the plug may be removed from the housing.
In addition, the housing defines a plurality of bores for receiving a plurality of pins and a plurality of springs which allow the plug to rotate when a key is inserted in a slot of the plug. However, the pins and springs are separate and distinct component from the plug. Therefore, to remove the pins and springs, the lock assembly must be disassembled which is difficult and time consuming.
Therefore, there remains a need to design a lock assembly having a universal drive member that accommodates both a first lock configuration and a second lock configuration while providing a way to detach the universal drive member from a core to allow the core to be replaced by a second core to lock and unlock the door without disassembling the lock assembly.
SUMMARY OF THE INVENTION AND ADVANTAGES
The present invention provides for a lock assembly having an arm coupled to a latch for selectively locking and unlocking a door using a key. The lock assembly includes a housing for mounting to the door with a core removably disposed in the housing. A first actuator is coupled to the housing for defining a first lock configuration and for engaging the arm to retract the latch to unlock the door. A second actuator is coupled to the housing independently from the first actuator for defining a second lock configuration and for engaging the arm to retract the latch to unlock the door. The core includes a keyway for receiving the key and is rotatable within the core between a locked position and an unlocked position. A universal drive member is coupled to the keyway and movable with the keyway between the locked and unlocked positions with the universal drive member interchangeably receiving the first actuator and the second actuator while the keyway remains in the core for interchanging the lock assembly between the first lock configuration and the second lock configuration.
The present invention therefore provides for a lock assembly having a universal drive member interchangeably receiving a first actuator and a second actuator while a keyway remains in a core for interchanging the lock assembly between a first lock configuration and a second lock configuration. In addition, the universal drive member is easily separable from the core to easily change the core with a second core without disassembling the lock assembly. Additionally, the lock assembly provides a way to reduce inventory by eliminating the need for multiple drive members and multiple housings for each of the first and second lock configurations, which ultimately reduces cost.

The housing 30 defines a plurality of blind holes 54 disposed on the back side 40 of the housing 30 for receiving a plurality of rim fasteners 56 to secure the housing 30 to the door 26 in a second lock configuration. A back plate 58 is coupled to the housing 30 and defines a plurality of cutouts 60 for receiving the rim fasteners 56 and for securing the housing 30 to the door 26. The first and second lock configurations refer to which actuator is being used and the way the lock assembly 20 is mounted to the door. The first lock configuration is commonly referred to as a mortise cylinder and the second lock configuration is commonly referred to as a rim cylinder. The mortise and rim cylinders will be further explained below.
Referring to FIGS. 3, 5-7, a core 62 is removably disposed in the housing 30. More specifically, the core 62 is disposed in the first chamber 32 and the second chamber 34 of the housing 30 with the first and second chambers 32, 34 of the housing 30 complementary in configuration to the core 62. The core 62 defines a plurality of bores 64 spaced from each other and having a plurality of pins 66 disposed in each of the bores 64 and a plurality of springs 68 with at least one of the springs 68 disposed in each of the bores 64 and abutting at least one of the pins 66. A cap 67 is disposed in the bore to retain the springs 68 and the pins 66 in the bores 64. The pins 66 and the springs 68 are contained in the core 62 which allows a user to easily remove the core 62 and replace the core 62 with a second core (not shown). The second core requires a different key to lock and unlock the door 26. By replacing the core 62 with the second core, the pins 66 and the springs 68 remain contained in the core 62 which prevents the need to disassemble the lock assembly 20 to remove and change the pins 66 to allow another key to unlock the door 26.
The core 62 includes a keyway 70 for receiving the key 28 and is rotatable within the core 62 between a locked position 74 and an unlocked position 76.

However, it is to be appreciated that the backing 136 may be secured to the washer 122 in any acceptable method of attachment known in the art. The hollows 138 of the backing 136 are spaced from the passage 130 of the backing 136. In addition, the hollows 138 of the washer 122 are spaced from the voids 118 of the washer 122. More specifically, the hollows 138 are spaced from the slit 134 of the washer 122.
Below is a discussion of using the lock assembly 20 to lock and unlock the door 26 and will assume, for illustration purposes only, that the lock assembly 20 is mounted to the door 26 in the first lock configuration. The key 28 is inserted in the slot 72 of the keyway 70 while in the locked position 74, which cause the pins 66 and springs 68 within the core 62 move to the appropriate position to allow the keyway 70 to turn. The keyway 70 rotates when the key 28 moves from the lock position to the unlocked position 76, which rotates the posts 98 and the universal drive member 90. Rotation of the universal drive member 90 causes the first actuator 86 to rotate and engage the arm 22 which retracts the latch 24 to unlock the door 26. To lock the door 26, the key 28 is rotated back from the unlocked position 76 to the locked position 74 which rotates the first actuator 86, the universal drive member 90, and the keyway 70 back to the locked position 74.
Below is a discussion of the differences between the mortise cylinder and the rim cylinder. The first lock configuration is shown in FIGS. 8, 10, and 11, and is commonly referred to as the mortise cylinder. The mortise cylinder includes the first actuator 86 and the threads 50 disposed on the body portion 48 of the housing 30. The mortise cylinder is coupled to the door 26 by threading the housing 30 into the door 26 by the threads 50 disposed on the body portion 48. The face plate 44 of the housing 30 abuts one side of the door 26 with the housing 30 extending a predetermined distance into the door 26. Meaning the mortise cylinder does not extend completely through both sides of the door 26. The first actuator 86 for the mortise cylinder is coupled to the universal drive member 90 in such a way as to allow the first actuator 86 to rotate and engage the arm 22 to retract the latch 24 and unlock the door 26.
The second lock configuration is shown in FIGS. 9, 12, and 13, and is commonly referred to as the rim cylinder. The rim cylinder includes the second actuator 88, the back plate 58, and the rim fasteners 56. The rim cylinder is coupled to the door 26 by the rim fasteners 56 and the back plate 58. Meaning the rim cylinder is disposed completely through the door 26 such that the back plate 58 is disposed on one side of the door 26 and the face plate 44 of the housing 30 is disposed on the other side of the door 26. The second actuator 88 for the rim cylinder is coupled to the universal drive member 90 in such a way as to allow the second actuator 88 to rotate and engage the arm 22 to retract the latch 24 and unlock the door 26.
Obviously, many modifications and variations of the present invention are possible in light of the above teachings. The foregoing invention has been described in accordance with the relevant legal standards; thus, the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and do come within the scope of the invention. Accordingly, the scope of legal protection afforded this invention can only be determined by studying the following claims.
