This disclosure relates generally to a lockable device and, more particularly, to a locking module for use in a lockable device.
Lockboxes typically provide a secured storage area for a key or other access aid at a location close to a locked property accessible by the key. In this way, an authorized user can unlock the lockbox to gain access to the secured storage area and then use the key contained therein to unlock the locked property.
The lockbox is typically attached to a door handle or to another stationary object near the traditional lock. The lock-box typically requires the user to demonstrate that he is authorized to obtain access to the locked property before the secured storage area is unlocked to allow the user to obtain the key. In a. mechanical lockbox, the user might be required to enter a correct lock combination to access the secured storage area. In an electronic lockbox, the user might be required to communicate a credential to lockbox (via a physical connection to the lockbox or via a wireless link to the lockbox) to access the secured storage area.
According to one embodiment, a locking module for selectively coupling a first component and a second component of a lockable device includes a locking member rotatable between an unlocked position and a locked position and an engagement member associated with said locking member. Translation of said engagement member drives movement of said locking member between said locked position and said unlocked position to selectively decouple said locking element from the second component.
In addition to one or more of the features described above, or as an alternative, in further embodiments the locking member further comprises a feature formed therein, the feature being receivable within an opening of the second component when the locking member is in the unlocked position.
In addition to one or more of the features described above, or as an alternative, in further embodiments said feature is received within said opening via a clearance fit when said locking member is in said unlocked position.

In addition to one or more of the features described above, or as an alternative, in further embodiments said locking member is mounted within said second component.
In addition to one or more of the features described above, or as an alternative, in further embodiments said engagement member includes one or more protrusions pinned to a portion of said locking member.
In addition to one or more of the features described above, or as an alternative, in further embodiments said locking member is rotated 90 degrees about said axis between said unlocked positon and said locked position.
In addition to one or more of the features described above, or as an alternative, in further embodiments comprising a mechanism associated with said engagement member, said mechanism being configured to translate said engagement member within a plane.
In addition to one or more of the features described above, or as an alternative, in further embodiments comprising a drive plate configured to apply a force to said engagement member and a biasing member associated with said drive plate, said biasing member being configured to bias the drive plate away from the engagement member.
In addition to one or more of the features described above, or as an alternative, in further embodiments said mechanism is a mechanical mechanism that operates the locking member in response to a user input.
In addition to one or more of the features described above, or as an alternative, in further embodiments said engagement mechanism is an electromechanical mechanism that operates the locking member in response to a user input.
In addition to one or more of the features described above, or as an alternative, in further embodiments the locking module is applied to a lockbox such that first component is a body of the lockbox and the second component is a keybox.
In addition to one or more of the features described above, or as an alternative, in further embodiments the locking module is applied to a lockbox such that first component is body of the lockbox and the second component is a shackle.
According to another embodiment, a method of operating a locking module of a lockable device includes operating a mechanism in response to a user input, translating an engagement member within a plane, and rotating a locking member coupled to said engagement member about an axis of rotation between a first position and a second position, said locking member including a feature selectively receivable within an opening of a movable component of the lockable device.
In addition to one or more of the features described above, or as an alternative, in further embodiments said feature is receivable within said opening when said locking member is in said second position.
In addition to one or more of the features described above, or as an alternative, in further embodiments said feature has a contour complementary to said opening when said locking member is in said second position.
In addition to one or more of the features described above, or as an alternative, in further embodiments said feature is not receivable within said opening when said locking member is in said first position.
In addition to one or more of the features described above, or as an alternative, in further embodiments comprising rotating said locking member about said axis between said second position and said first position to selectively couple said movable component to the lockable device.
The subject matter is particularly pointed out and distinctly claimed at the conclusion of the specification. The foregoing and other features, and advantages of the present disclosure are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
The detailed description explains embodiments of the present disclosure, together with advantages and features, by way of example with reference to the drawings.
Referring now to
A locking module 40 (see
With reference now to
The contour of the feature 46 is selected such that when locking member 42, and therefore the feature 46, is in a first locked position, the feature 46 is not receivable within the opening 48. However, when the locking member 42 and feature 46 is in a second unlocked position, the feature 46 is receivable within the opening 48, such as via a clearance fit for example. As a result, when the locking member 42 is in the second, unlocked position, the keybox 30 is movable relative to the locking member 42 and the body 22. In the illustrated, non-limiting embodiment, the feature 46 is generally rectangular in shape and has a greater width than thickness. In the locked position, the width of the feature 46 exceeds the size of the opening 48, thereby restricting movement of the keybox 30 relative to the locking member 42. In the unlocked position, however, the feature 46 is oriented generally vertically such that the thickness of the feature 46 is smaller than the size of the opening 48. It should be understood that the feature illustrated and described herein is intended as an example only and a feature 46 and opening 48 having any configuration are within the scope of the disclosure.
The locking module 40 additionally includes an engagement member 50 movable relative to the body 22 and keybox 30. The engagement member 50 engages a portion of the locking member 42 to transform the locking member 42 between the first locked position and the second unlocked position. In the illustrated non-limiting embodiment, the engagement member 50 includes a link having one or more protrusions 52 pinned to one or more protrusions 54 extending from the locking member 42. However, it should understood that any type of engagement member 50 configured to cooperate with the locking member 42 is contemplated herein.
The engagement member 50 is configured to move in response to operation of a mechanism 56, operably coupled to the engagement member 50. As shown, the mechanism 56 includes a drive plate 58 having a post 60 at least partially received within a corresponding opening (not shown) of the engagement member 50. The mechanism 56 is moved generally linearly to apply a vertical force to the engagement member 50. In an embodiment, the mechanism 56 includes a biasing member 62, such as a coil spring for example, configured to bias the drive plate 58 to a default position, away from the engagement member 50. The mechanism 56 for moving the engagement member 50 may be mechanically operated by a user, or alternatively, may include an electromechanical mechanism, such as a motor, solenoid, or a piezoelectric device for example, directly or indirectly coupled to the engagement member 50. In such embodiments, the mechanism 56 may be operable in response to an electrical input, such as generated by a code entered via a key pad or upon detection of an identification device, such as an RFID tag for example, having acceptable credentials.
In operation, a user provides an input to operate the mechanism 56 associated with the engagement member 50. In response to the input, the mechanism 56 causes the engagement member 50 to translate within a plane. As a result of the connection between the engagement member 50 and the locking member 42, the linear movement of the engagement member 50 causes the locking member 42 to rotate about its axis. The axis of the locking member 42 is oriented generally parallel to the plane within which the engagement member 50 is configured to translate. As the locking member 42 rotates about its axis, the locking member 42 transitions from a locked position to an unlocked position, thereby allowing the keybox 30 to translate relative to the locking module 40 and the body 22.
To reconnect the keybox 30 to the body 22, the feature 46 is aligned with and received within the opening 50. The mechanism 56 is operated to translate the engagement member 50 in an opposite direction, causing the locking member 42 to rotate from the unlocked position to the locked position. Initiation of this operation of the mechanism 58 may occur once the keybox 30 is fully inserted, or alternatively, may occur in response to a switch (not shown) activated as the keybox 30 is slidably inserted into the body 22. In the event that the user is not an authorized user, the drive plate 58 will move relative to the engagement member 50, but the engagement member 50 will not translate in response to the movement of the drive plate 58. Rather, the biasing member 62 will compress and bias the drive plate 58 back to its original position.
The locking module 40 illustrated and described herein has a simplified configuration resulting in a reduced cost. Further, the compact design of the locking module 40 eliminates the required space within the keybox 30 and body 22.
While the present disclosure has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the present disclosure is not limited to such disclosed embodiments. Rather, the present disclosure can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate in spirit and/or scope. Additionally, while various embodiments have been described, it is to be understood that aspects of the present disclosure may include only some of the described embodiments. Accordingly, the present disclosure is not to be seen as limited by the foregoing description, but is only limited by the scope of the appended claims.
