Patent Application
20160337856
This disclosure relates generally to the field of electronic lock and key devices.
A property owner who is selling a property by herself or renting the property on the market must stay close to the property in order to complete the check-in and check-out process of accessing the property. Typically, access is gained by using a keyed door or gate. If the owner cannot be near the property, several problems occur. The owner may put the key in an insecure or hidden place, such as under the door mat or under a flower pot. The visitor often then needs to communicate with the owner to find the key. In addition, some visitor may forget to return the key when they check out. Furthermore, owners may place the key in an analog key box and its pass-code needs to be memorized and changed periodically. In other cases, the owner may install a digital door lock which permanently changes the door configurations. In addition, many electronic key boxes requires the visitors to install an App on their phone or to hold a pre-delivered device, such as an RFID tag. Not all visitors can meet these requirements.
Many door locks controlled by Internet Applications accidentally open or close when no one is home. Some systems require a Wi-Fi connection for the digital door to function, and the digital door lock may be out of Wi-Fi range. Furthermore, if the owner has a multi-family property, the above problems become even more cumbersome. Real-time human interaction can be unreliable and costly. An analog key box gives both the owner and the visitor several procedures to memorize and execute. Digital door locks require constant changing of the lock's configurations, and many require the visitor to install a mobile Application. It is clear that a solution is needed that allows for remote access to tenants or agents of the owner without having to coordinate with the owner to locate the key while maintaining a high level of security.
A system for controlling key access using a key box comprising a chamber for holding a key device; a circuit board coupled to a locking mechanism configured to lock or release the chamber; an antenna coupled to the circuit board for receiving and transmitting wireless phone signals to a trigger release of the chamber; and a *SIM card coupled to the circuit board and antenna; the SIM card comprising a unique phone number registered to the key box, and the phone number accessed wirelessly by a user to access the key device in the chamber.
The disclosed invention comprises an Internet-connected key box device that provides the owner the means to remotely manage “check-in” and “check-out” activities of a visitor in a unique way. A pre-approved visitor can access the key within the Internet-connected key box device by calling the device on his phone, with no other technology involved from the visitor's point of view.

It is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, or a particular claim, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention.
Certain terminology and derivations thereof may be used in the following description for convenience in reference only, and will not be limiting. For example, words such as “upward,” “downward,” “left,” and “right” would refer to directions in the drawings to which reference is made unless otherwise stated. Similarly, words such as “inward” and “outward” would refer to directions toward and away from, respectively, the geometric center of a device or area and designated parts thereof. References in the singular tense include the plural, and vice versa, unless otherwise noted.
The term “comprises” and grammatical equivalents thereof are used herein to mean that other components, ingredients, steps, among others, are optionally present. For example, an article “comprising” (or “which comprises”) components A, B and C can consist of (i.e., contain only) components A, B and C, or can contain not only components A, B, and C but also contain one or more other components.
Where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where the context excludes that possibility), and the method can include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all the defined steps (except where the context excludes that possibility).
The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a range having an upper limit or no upper limit, depending on the variable being defined). For example, “at least 1” means 1 or more than 1. The term “at most” followed by a number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4, and “at most 40%” means 40%or less than 40%. When, in this specification, a range is given as “(a first number) to (a second number)” or “(a first number)-(a second number),” this means a range whose limit is the second number. For example, 25 to 100 mm means a range whose lower limit is 25 mm and upper limit is 100 mm.

U.S.C. §112 ¶ 6. Specifically, the use of “step of” in the claims herein is not intended to invoke the provisions of U.S.C. §112 ¶ 6.
Referring to
In an alternative embodiment, the key box 201 acknowledges key-return via an RFID tag-key method rather than the method described above. In an alternative embodiment, the system comprises a load cell which recognizes the weight of the key chamber 208 to differentiate between an empty chamber and a chamber containing a key.
The embodiment in
The embodiment in
The circuit board 202 comprises a microcontroller unit to store and run the needed programs on the software application. Alternatively, a printed circuit board 202 can function as the system's circuit board 202. Embodiments of the device also comprise one or more batteries, a battery chamber, and insulated copper wiring of sufficient length to connect the circuit board 202.
One or more embodiments of the system comprise a servo and a spring mechanism of sufficient tension to eject the key chamber 208 once the key chamber latch 210 is disengaged. This embodiment features a chamber dispenser spring which pushes the key chamber 208 out of the key box 201 as soon as the tip of the key chamber latch 210 is released. Other embodiments comprise an optional load cell and switch. Other embodiments comprise an optional rotation plate.
Further describing the embodiments shown in
In one or more embodiments, a rotation plate is on the top portion of the key box 201 and would connect to the hook. Specifically, the circuit board 202 receives a message from the software application and commands the servo to rotate to release the key chamber latch 210 to open the key chamber 208. In the same embodiment, if the circuit board 202 commands the servo rotate in the other direction, it opens the hook latch 212 to release the hook. In another embodiment, a hook release button can also release the hook latch 212. In this embodiment, the owner 301 pushes the hook release button to release the hook from the rotation plate.
Other embodiments feature a hook and body assembly, wherein the hook is disengaged from the body of the key box 201 at one of two anchor points. Once unhooked at one anchor point, gravity and a potential tug from the user or owner 301 will pull the hook away from the body of the key box 201. The hook is reattached at the same anchor points.
In another embodiment of the invention, the key box 201 is attached to a wall or fixture with a mounting assembly. In this embodiment, the hook and hook latch 212 features are no longer necessary, as the mounting assembly is either removable or comprises a mount latch which allows the key box 201 to detach from the wall or fixture.
Electronically, in several embodiments, a program is installed in the circuit board 202 as firmware. This firmware receives input from the communication module 203, the switch, the optional load cell, the power button 207 and the software application via Internet connection. The communication module 203 uses 2G, 2.5G, 3G, 3.5G, 4G, 5G or the current standard in practice at the box's location, at 850, 900, 1800 or 1900 MHz or other optimal frequency performance established by the communication module 203. The firmware then sends output to the display 206, the servo and the software application via Internet connection established by the communication module 203. The software application also takes data from the circuit board 202 and inserts it into the database 307.
In several embodiments, the software application may show data and on the owner 301's personal computer 308 or smart phone 304 device via the software application. The software application may also send data to the database 307, processes commands on the server 306, and communicate with the owner 301 and visitor 302s by sending them notifications. The software application may send notifications via SMS, e-mail, direct phone 304 calling, or other convenient means.
In several embodiments of the system, the owner 301 initially inputs visitor 302 data, including the owner 301's and visitor 302's name, phone 304 number, address, and check-in check-out schedule into the database 307 via the software application. The software application may also process data such as weight of objects inside the key chamber 208 via the optional load cell. The software application may also gather, process and utilize information such as battery status and geographic location of the key box 201.
In at least one embodiment of the invention, the software application gives a “time-stamp” to every action taken by owner 301 and visitor 302. The software application may produce web portal display 206s, or “web pages,” that may show the owner 301 or user's calendar, maintain a chronological schedule of dwelling visitor 302s, maintain an address book of various visitor 302s′ data, and may maintain and process data about various states and actions of the key box 201.
In alternative embodiments of the present invention, the key box 201 may comprise multiple key chambers 208 or attached key chamber 208 modules. The multiple key chamber 208 modules may efficiently share the same communication module 203 and the same mobile Internet connection. An optional USB connector may connect to other key box 201es or other key chambers 208 via a daisy-chain connection and may utilize the same software application.
This application claims priority to U.S. Provisional Application No. 62/161,448 filed May 14, 2015. The content of the above application is incorporated by reference in its entirety.
