For example, a lockbox can be installed outside a residence and hold a key for accessing the residence. The lockbox can be configured to be accessible by emergency responders, for example, by being keyed to an emergency responder master key. Accordingly, the first responders can easily access the lockbox and then gain entrance to the residence. However, because the lockbox holds an access key to the residence, it is important that the structure of the lockbox be secure to prevent unauthorized access by, for example, prying open or otherwise breaking into the lockbox.
- In some embodiments, a lockbox includes a base having a first engagement structure and a cover having a second engagement structure configured to slidingly engage 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. The first and second engagement structures may be located substantially within the enclosed volume. In some embodiments, 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. 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.
- In some embodiments, a lockbox includes a base having a first engagement structure and a cover having a second engagement structure configured to engage with the first engagement structure. The lockbox may further include a locking mechanism configured to selectively secure to the base and the cover. The locking mechanism may include a cam. The locking mechanism may include a locking member. The base may include a groove, and at least a first portion of the locking member may selectively engage with the groove and a second portion of the locking member may selectively engage with the cover. The first and second engagement structures may be configured to slidingly engage.
- In some embodiments, a method of securing a lockbox having a base and a cover includes slidingly engaging the cover with the base, the cover and the base defining an enclosed volume therein. The method may further include locking the cover to the base. The method may further include aligning a first engagement structure of the base with a second engagement structure of the cover. The first and second engagement structures may permit movement of the cover relative to the base in a single direction when the first and second engagement structures are engaged. One of the first and second engagement structures may include at least one groove and the other one of the first and second engagement structures may include at least one rail.

FIGS. 2A through 2F show various views of thebase 200 of thelockbox 100 ofFIG. 1A .FIG. 2A shows a perspective view of thebase 200.FIGS. 2B through 2E show front, back, and right and left side views of thebase 200, respectively.FIGS. 2F and 2G show bottom and top views of thebase 200, respectively. In some embodiments, thebase 200 is configured to be securely attached to a wall or other structure. Thecover 300, discussed in detail in reference toFIGS. 3A through 3F below, may then be selectively coupled with the base 200 to define the enclosed volume of thelockbox 100. Thebase 200 and thecover 300 may then be securely locked to each other using thelocking mechanism 400 to restrict access to the contents of thelockbox 100. - In certain embodiments, the
base 200 includes abody 201 which may have afirst portion 210 and asecond portion 250. Thefirst portion 210 includes aback surface 212, afront surface 214, side surfaces 216, and atop surface 218. The bottom surface of thefirst portion 210 may be joined to (either attached to or integrally formed with) thesecond portion 250. A portion of the side surfaces 216 and thetop surface 218 may contact or otherwise engage with a portion of thecover 300 when thecover 300 is selectively coupled to thebase 200. Thefront surface 214 of thefirst portion 210 is substantially located within the interior of thelockbox 100 when thecover 300 is selectively coupled to thebase 200. Theback surface 212 may be configured to contact, at least in part, a wall or other structure to which thebase 200 is attached. In some embodiments, other structures, for example a mounting bracket or sealing gasket may be positioned between theback surface 212 and the wall or other structure to which thebase 200 is mounted. In some embodiments, thebase 200 may not be secured to a wall or other structure. - As shown in

Thehook 213 is positioned so as to be located within the internal volume of thelockbox 100 when thecover 300 is selectively coupled to thebase 200. Thehook 213 may be used to support keys or other items within thelockbox 100. In some embodiments, thehook 213 may be replaced or supplemented with other fasteners or mounts for securing or supporting items within the interior of thelockbox 100. For example, thebase 200 may include a magnet to secure a key or other magnetic item. Or, thebase 200 may include a shelf or other supporting structure extending from thefront surface 214 and be configured to support a key or other item within the interior of thelockbox 100. In some embodiments, these features may be omitted. In some embodiments, these features may be integrated into thecover 300 and/or thesecond portion 250 of thebase 200. - The
body 201 of the base 200 may also include thesecond portion 250. In the illustrated embodiment, thesecond portion 250 is integrally formed with thefirst portion 210 and extends substantially orthogonally from thefirst portion 210. Thefirst portion 210 and thesecond portion 250 may be attached to each other such that thebody 201 of thebase 200 is substantially L-shaped. In some embodiments, thefirst portion 210 and thesecond portion 250 may be attached to each other so that thebody 201 is formed in other substantially concave shapes, that is, the angle between thefirst portion 210 and thesecond portion 250 may be greater than or less than 90 degrees. In some embodiments the angle between thefirst portion 210 and thesecond portion 250 may be approximately 45 degrees. In some embodiments the angle between thefirst portion 210 and thesecond portion 250 may be approximately 135 degrees. In some embodiments, either thefirst portion 210 or thesecond portion 250 may be omitted. - The
second portion 250 includes abottom surface 252, atop surface 254, side surfaces 256, and afront surface 258. A portion of the side surfaces 256 and thefront surface 258 of thesecond portion 250 may be positioned to contact or otherwise engage with a portion of thecover 300 when thecover 300 is selectively coupled to thebase 200. Thetop surface 254 is positioned so as to be located substantially within the interior of thelockbox 100 when thecover 300 is selectively coupled to thebase 200. Accordingly, thefront surface 214 of thefirst portion 210 and thetop surface 254 of thesecond portion 250 partially define the enclosed volume of thelockbox 100 in some embodiments. - The
locking mechanism 400 may be disposed in thebase 200 and/or thecover 300. In the illustrated embodiment, thelocking mechanism 400 extends through thesecond member 250 of the base 200 such that a portion of thelocking mechanism 400 is located on the exterior of thelockbox 100 and another portion of thelocking mechanism 400 is located within the interior of thelockbox 100 when thecover 300 is selectively coupled to thebase 200. As discussed above, thelocking mechanism 400 can be any suitable mechanical or electronic locking mechanism as known in the art. In the illustrated embodiment, thelocking mechanism 400 is a tumbler lock which can be rotatably locked and unlocked with a corresponding key. As shown inFIG. 2F , thelocking mechanism 400 includes alock cylinder 401 with akeyhole 403. Thekeyhole 403 may be accessible on or below thebottom surface 252 of thesecond portion 250.

In some embodiments, the lockingmember 410 may be rotatable and may engage with a portion of thebase 200 and/or thecover 300 when rotated into a locked position. The lockingmember 410 may provide sufficient clearance between the base 200 and/or thecover 300 when rotated into an unlocked position to allow thecover 300 to be removed from thebase 200. For example, the lockingmember 410 may be a rotatable arm or cam. As shown inFIG. 2E , the lockingmember 410 is configured with a substantially oval shape that is longer in a first direction than it is wide in a second direction. As shown in the illustrated embodiment, thefirst portion 210 of the base 200 may include agroove 215 configured as a recess in thefront surface 214 positioned and sized to receive a portion of the lockingmember 410 therein when the lockingmember 410 is rotated into the locked position. - The
second portion 250 of the base 200 may also include abase catch 280 configured to engage with acorresponding cover catch 380 of thecover 300 when thecover 300 is selectively coupled and locked to thebase 200. Thebase catch 280 may extend from thetop surface 254 of thesecond portion 250. In some embodiments, thebase catch 280 is integrally formed with thesecond portion 250. In some embodiments, thebase catch 280 is formed separately from thesecond portion 250 and attached by welding, mechanical fasteners, or other suitable methods. As shown inFIGS. 2D and 2E , thebase catch 280 may include anundercut surface 281. The undercutsurface 281 may engage with a corresponding undercutsurface 381 on thecover catch 380 to prevent thecover 300 from being lifted away from the base 200 when thecover 300 is selectively coupled with and locked to the base 200 as best seen inFIG. 7B . - In certain embodiments, the
base 200 includes engagement structures configured to limit movement of thecover 300 relative to the base 200 in at least one direction when thecover 300 is selectively coupled to thebase 200. These engagement structures may include one ormore grooves first portion 210 and/or one ormore recesses 261 formed in thesecond portion 250. In some embodiments, this arrangement may be reversed with the one ormore grooves second portion 250 and the one ormore recesses 261 formed in thefirst portion 210. In embodiments having more than onegroove grooves more grooves 241 are perpendicular to the one ormore grooves 243.

As will be recognized, the present invention may be embodied within a form that does not provide all of the features and benefits set forth herein, as some features may be used or practiced separately from others. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
- The foregoing description details certain embodiments of the systems, devices, and methods disclosed herein. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the systems, devices, and methods may be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the technology with which that terminology is associated.
- It will also be appreciated by those of skill in the art that parts included in one embodiment are interchangeable with other embodiments; one or more parts from a depicted embodiment may be included with other depicted embodiments in any combination. For example, any of the various components described herein and/or depicted in the Figures may be combined, interchanged, or excluded from other embodiments.
- With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art may translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
- It will be understood by those within the art that, in general, terms used herein are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
- The term “comprising” as used herein is synonymous with “including,” “containing,” or “characterized by,” and is inclusive or open-ended and does not exclude additional, unrecited elements or method steps.
- The above description discloses several methods of manufacture and materials of the present development. This development is susceptible to modifications in the methods and materials, as well as alterations in the fabrication methods and equipment. Such modifications will become apparent to those skilled in the art from a consideration of this disclosure or practice of the development disclosed herein. Consequently, it is not intended that this development be limited to the specific embodiments disclosed herein, but that it cover all modifications and alternatives coming within the true scope and spirit of the development as embodied in the attached claims.
