Lockbox

Abstract

A lockbox is disclosed having a base that includes a first engagement structure and a cover that includes a second engagement structure that slidingly engages with the first engagement structure. The lockbox may further include a locking mechanism configured to secure the cover to the base. The base and the cover may define an enclosed volume when the cover is secured to the base and the first and second engagement structures may be located substantially within the enclosed volume. The first and second engagement structures may permit movement of the cover relative to the base in only a single direction when engaged. One of the first and second engagement structures may be at least one groove and the other one of the first and second engagement structures may be at least one rail.

What is claimed is: 
     
         1 . A lockbox, comprising:
 a base including a first engagement structure;   a cover including a second engagement structure configured to slidingly engage with the first engagement structure; and   a locking mechanism configured to secure the cover to the base.   
     
     
         2 . The lockbox of  claim 1 , wherein the base and the cover define an enclosed volume when the cover is secured to the base, and wherein the first and second engagement structures are located substantially within the enclosed volume. 
     
     
         3 . The lockbox of  claim 1 , wherein the base further comprises a first portion connected to a second portion, wherein the first portion is substantially orthogonal to the second portion. 
     
     
         4 . The lockbox of  claim 1 , wherein the first and second engagement structures are configured to permit movement of the cover relative to the base in a single direction when the first and second engagement structures are engaged with each other. 
     
     
         5 . The lockbox of  claim 4 , wherein one of the first and second engagement structures comprises at least one groove and the other one of the first and second engagement structures comprises at least one rail. 
     
     
         6 . The lockbox of  claim 5 , wherein the single direction is aligned with a central axis of at least one of the at least one groove and the at least one rail. 
     
     
         7 . The lockbox of  claim 1 , wherein the locking mechanism comprises a locking member, and wherein the base comprises a base catch and the cover comprises a cover catch, and wherein the locking member is configured to selectively engage the base catch, and wherein the base catch is configured to engage the cover catch when the locking member engages the base catch. 
     
     
         8 . A lockbox, comprising:
 a base including a first engagement structure;   a cover including a second engagement structure configured to engage with the first engagement structure; and   a locking mechanism configured to selectively secure to the base and the cover.   
     
     
         9 . The lockbox of  claim 8 , wherein the locking mechanism comprises a cam. 
     
     
         10 . The lockbox of  claim 8 , wherein the locking mechanism comprises a locking member, the locking member being rotatable. 
     
     
         11 . The lockbox of  claim 10 , wherein the base comprises a groove, and wherein at least a first portion of the locking member is configured to selectively engage with the groove and a second portion of the locking member is configured to selectively engage with the cover. 
     
     
         12 . The lockbox of  claim 11 , wherein when the locking member is in a first rotational position the first and second portions engage with the groove and the cover, respectively, and wherein when the locking member is in a second rotational position the first and second portions are disengaged from the groove and the cover. 
     
     
         13 . The lockbox of  claim 8 , wherein the first and second engagement structures are configured to slidingly engage with each other. 
     
     
         14 . The lockbox of  claim 8 , wherein one of the first and second engagement structures comprises at least one groove and the other one of the first and second engagement structures comprises at least one rail. 
     
     
         15 . The lockbox of  claim 8 , wherein one of the first and second engagement structures comprises at least one internal wall and the other one of the first and second engagement structures comprises at least one recess. 
     
     
         16 . The lockbox of  claim 15 , wherein the at least one internal wall comprises a bottom end, and wherein the bottom end is disposed in the at least one recess when the second engagement structure is engaged with the first engagement structure. 
     
     
         17 . A method of securing a lockbox having a base and a cover, the method comprising:
 slidingly engaging a cover with a base, the cover and the base defining an enclosed volume therein; and   locking the cover to the base.   
     
     
         18 . The method of  claim 17 , further comprising aligning a first engagement structure of the base with a second engagement structure of the cover. 
     
     
         19 . The method of  claim 18 , wherein the first and second engagement structures are configured to permit movement of the cover relative to the base in a single direction when the first and second engagement structures are engaged. 
     
     
         20 . The method of  claim 18 , wherein one of the first and second engagement structures comprises at least one groove and the other one of the first and second engagement structures comprises at least one rail.
