Cross-Reference to Related Applications
[1.] This application claims priority under 35 USC §119(e) to US Provisional Patent Application Serial No. 61/980,644, filed in the USPTOon April 17, 2014, which is incorporated by reference for all purposes.
Background
[2.] In the internet age, more and more consumers of the world rely on companies such as Ama20n.com in the US, and many other online retailers in other parts of the World to shop, and to receive their parcels when they are away. When the value of parcel increases and when the recipient is away, the delivery person often either chooses to leave a note at the front-door asking the recipient to collect the parcel at a later time from a nearby pick-up locations of the carrier, or attempts to re-deliver at a later point of time. Both these options cause tremendous time delays and inconvenience, and defeat the original objective of shopping online in a very time-efficient manner from the comfort of one's home or office. Past attempts to solve the problem of receiving deliveries while the recipient is away at work or outside their temporary or permanent residences or place of their businesses have been unsatisfactory.
[3.] Additionally, many luxury apartment complexes, hotels and other places of stay do not allow their residents to permanently alter or do anything outside their front door to help the resident(s) to securely receive packages delivered by UPS, FedEx, DHL, onTrac or any other mail carrier. In fact, many luxury apartments, in the hope of offering their elite residents a clutter-free appearance in the hallway and/or exquisite living experience in their property, have very strict rules, and impose many restrictions for living. Residents are not allowed to leave anything outside their front-door even for a few hours, and property managers and staff frown upon and even impose fines on residents who violate any of their strict rules.

SUMMARY OF THE INVENTION
[5.] The above-listed attempts by other inventors at providing a mechanism to address the growing need to securely receive parcels at a doorstep in my opinion is still inadequate and does not address all the limitations and constraints for practical implementations. In addition , none of them fully addresses all of the practical issues, and include all of the features of my invention mentioned below. The various embodiments of the present invention utilize pre-existing doorknobs or door handles. The entire assembly or apparatus, which includes a novel doorknob lock assembly, is portable and can be quickly and easily, attached or detached, and carried along. There is no need to do any drilling or installation of any permanent or semi-permanent mounting brackets or time-consuming setups at the time of use that cause any damage to the front-door or any of its adjacent vicinity to make this operational in order to fulfill the intended objectives. The entire assembly can be securely installed or removed within a few minutes on the day of its intended use. A one-way locking mechanism in a parcel bag allows the delivery personnel to deliver, lock and secure the package so that only the intended recipient is able to have access to the parcel. An optional audible intrusion alarm sounds to deter any unauthorized tampering or forceful entry or actions to retrieve contents of the parcel bag. The invention uses a tamper-proof cable, rope or chain to secure the entire assembly. The various embodiments use flexible or rigid or semi-rigid parcel bag of varying size to accommodate receipt of most common sizes of packages to suit ones shopping needs.
[6.] The following essentially summarizes the key elements of the various embodiments, and the details of its operation are described in other pertinent sections:
[7.] Doorknobs or Door handles: The various embodiments of the invention involve utilizing
the doorknobs and/or door handles for achieving its purposes. Doorknobs are of two types, a)
circular [Figure 1a] and b) non-circular [Figure 1b]. Door handles are of many types as shown
in Figure 1c.
[8.] Secure: None of the elements of my mechanism can be removed by any unauthorized
individuals.
[9.] Portable: This method and mechanism can be packed up in a bag or suitcase and can be
taken along during travel to utilize it wherever and whenever necessary.

[10.] Non-intrusive: This method and mechanism neither damages nor alters anyone's property at its place of use and can be utilized jjst on the day or a few hours of its intended use, and can be removed entirely and stored inside at all other times,
[11.] Removable & Temporary: The various embodiments are removable and NOT permanently attached to anything. Once the parcel is received and objectives are met, it can be removed and stored inside.
[12.] A Parcel bag: The various embodiments involve utilization of a tamper-proof, flexible or rigid or semi-rigid bag that can be used by a mail carrier to deliver the parcel. This bag can be kept outside one's front-door for a mail carrier to drop off the package and lock it up for the parcel recipient to retrieve later on.
[13.] One-way Locking Mechanism: There are two places where locking mechanisms could be potentially utilized in this method, mechanism and apparatus. First, close to the doorknob or door handle to secure and tighten the cable or rope or chain mechanism to prevent removal of the doorknob lock assembly from the doorknob or door handle. Second, a lock to secure the parcel bag after placing the package inside it and to ensure the mail personnel can lock it prior to his/her departure upon delivery. By one-way, it is inferred that a delivery personnel can put a package or parcel inside a bag, but not be able to remove upon locking the parcel bag assembly. No one, not even the mail carrier, can access the package upon locking the parcel bag. Only the recipient will be able to access and retrieve the parcel. The locking and unlocking mechanism can be a) simple, conventional physical type involving combination locks or traditional locks or can optionally have other embodiments and utilize latest advancement in technologies such as b) RFID, c) Bluetooth d) mobile phone related applications or e) Wi-Fi. [14.] Intrusion and Audible Alarm: The various embodiments optionally utilize installation of an intrusion alarm system if the cable or rope or chain is pulled forcefully or if the parcel bag and/or lock(s) is attempted to be opened or tampered with. The sound alarm will last for a preset time interval so as to not drain a battery and at the same time deter unauthorized person(s) from continuing their intrusion or tampering. This optional feature will be an embodiment where additional security is desired in certain locations or applications. An additional embodiment is also to have a feature where the decibel level of the sound and time duration of the alarm can be adjusted.

DETAILED DESCRIPTION OF THE DRAWINGS
[17.] Figures 1a through 1c show examples of various types of doorknobs and handles. The various embodiments can be installed on any of these door handles and utilized to receive a parcel securely These circular doorknobs are displayed herein to facilitate explanation of usage of the various embodiments- Figure 1b illustrates examples of straight-shaped doorknobs. The various embodiments can be installed on any of these straight-shaped doorknobs and utilized to receive a parcel securely. These are displayed herein to facilitate explanation of usage of the various embodiments. Figure 1c shows examples of various door handles. The various embodiments of the invention can be installed on any of these door handles and utilized to receive a parcel securely.
[18.] Figure 2a illustrates at a high-level how the various embodiments operate on a circular doorknob, and shows all the associated components. Two sections of figure 2a are enlarged, and are displayed as detail A and detail B for better clarity. Figure 2b shows an enlarged version of Figure 2a, detail A.
[19.] Figure 2c shows an enlarged version of Figure 2b, specifically showing how the cable/rope/chain (108a and 108b) is wrapped around the neck of a circular doorknob. In this picture, the cable 108a and 108b appears loose around the neck of the circular doorknob for illustrative purposes only. It should be noted that it is tightly wrapped around the neck without any room for the cables to be removed.

[20.] For the purposes of this invention, the word 'cable" as used herein denotes a flexible member made of metal or non-metal, of sufficient strength, flexibility and characteristics to suit the intended application. As used herein, 'cable" refers to a rope or chain or cable, of any suitable material.
[21.] Figure 3 illustrates at a high-level how the various embodiments work on a straight doorknob, and shows all the associated components. Two sections of figure 3 are enlarged and are shown as detail A and detail B for better clarity,
[22.] Figure 4 illustrates at a high-level how the entire mechanism works on a door handle, and shows all the associated components. Two sections of figure 4 are enlarged, and are shown as detail A and detail B for better clarity.
[23.] Figure 5a shows a simple doorknob lock assembly embodiment that can be utilized to securely fasten to a doorknob using a cable/rope/chain (108a, 108b), and a lock/key (120). This apparatus utilizes one extendable spring 124, and when cable 108b is pulled out to wrap it around the neck of a doorknob, this spring 124 is extended, and when it is released, this spring pulls the inverted T-shaped sliding block (119) back toward its original position so that the cable/rope/chain 108b remains tight around the neck of a doorknob.
[24.] Also, it is extremely important to note that the location of lockykey 120 as shown in the figure is for descriptive purposes only. Specifically, the location of 120 can be on any of the faces of the assembly as it should be located conveniently to operate on doors where the space around the doors may be very limited depending on whether a) the doorknob is located on the left-side of the front-door, or b) on the right-side of the front-door, etc. Ideally, the lock 120 is expected to be located on the top face of the assembly so that it is very convenient to operate the lock in any kind of doorknobs located on any (right or left) sides of the front doors, and may not be situated as shown in some of these figures. Figure 5b and figure 5c shows two different perspectives of figure 5a for better visualization and understanding. Figure 5d shows an exploded version of figure 5a, and has all the essential components of it nicely separated from each other for enhanced clarity and distinction.
[25.] Figure 6a through 6e illustrates how the cable/rope/chain (108a, 108b) at the edge of stem (107) are pulled out and extended (Figure 6a, 6b). Once the cable is stretched to the required diameter (Figure 6c) around a doorknob (such that it has been secured around it and may not

be tampered with), and once the cable/rope/chain is extended sufficiently over doorknob, it is slowly released, and because of spring (124, 12S) actions, the cable diameter decreases and shrinks (Figure 6d, Figure 6e) and contracts to tighten itself around the doorknob tightly and securely.
[26.] Figure 7a, 7b and 7c are further extensions of Figure 6a through 6e, and shows how the doorknob is centered inside the almost circular shape of cable/rope/chain (108a, 108b). Arrows are shown in these figures to explain movement of cable/rope/chain at different stages.
[27.] Figure 8a through 8c show embodiments in which there are two additional compressible springs (125) that are placed to facilitate the movement of the sliding block 119 to go back to its original position once the cable/rope/chain 108b is extended. The spring 125 is compressed when cable 108b is pulled out, thereby, once the cable 108b is over the neck of the doorknob and released, this compressed spring automatically act on the sliding block 119 and push it back toward its original position.
[28.] Figures 9a through 9e illustrate the design and use of a third embodiment. In this embodiment, the inverted t-shaped sliding block 119 is replaced by a circular gear mechanism. The limitation of inverted t-shaped sliding block 119 is that the maximum length that the 108b can be pulled is constrained and limited by the length of the sliding assembly, and has to be of finite length only. However, this circular gear rotates when cable 108b is pulled out through its connecting cable 123. Because of the circular gear shape, the cableyrope/chain 108b can be pulled out substantially more in this embodiment, and as such there is no strict limitation as to how long one can pull the cable 108b to wrap it around a doorknob or any other object.
[29.] In the embodiment illustrated in Figures 9a-9e, springs (124, 125) are replaced by a helical spring located concentrically inside the circular gear, and this helical spring helps in pulling back cable 108b to ensure the cable 108b wraps around the neck of a doorknob tightly and securely. Other devices may replace the helical spring by providing a similar retraction (and tensioning) function, and, as such, the helical spring is described herein to communicate the idea in a descriptive sense only for a particular embodiment.
[30.] Figures 10a through 10g illustrate the design and use of a fourth embodiment. In the fourth embodiment the helical spring is not concentrically inside the annular space 131 that contains

the cable/rope/chain 108b, but is laterally extended out and is positioned outside and alongside or its own circular cylinder 135. So, this embodiment tends to be slightly larger than the third embodiment shown in figures 9a through 9c, However this design is less complicated and less intricate than the earlier design, and so it is easier to maintain and replace broken, defective or failed parts in case of any problems associated with any of its components such as springs, or cables etc in case they require repair upon usage.
[31.] Figures 11a and 11b illustrate the parcel bag feature of the various embodiments in its open and closed state, respectively. Figure 11a in addition shows the cable/rope/chain 102 that is connected between the parcel bag and the doorknob assembly 101. Also, in Figure 11a, the zipper 139 is in open position, while in Figure 11b, the zipper 139 is in closed position securely tucked inside the parcel bag lock 104.
[32.] Figures 12a and 12b show parcel bags where the Y-shaped cable 113 is integrated with a riveted 115 lock 114 that are specifically used in applications involving door handles. Figure 12c shows an exploded view of detail A displayed in Figure 12b, wherein the Y-shaped cable 113 is used to wrap around a door handle to secure the parcel bag to a door handle.
[33.] Figure 13 illustrates how a RFID (Radiofrequency identification) can be used in lieu of a traditional lock 120 to arrest and release the movement of cable/rope/chain 108b around a doorknob. Figure 13 also displays an optional embodiment of including a speaker 142 to sound an alert if any kind of tampering is noticed or detected on the doorknob assembly or on the interconnecting cable/rope/chain or on the parcel bag.
[34.] Figure 14 shows an embodiment that does not have RFID, and instead, it can have any other types of technological solution to replace the functions of the lock 120. The lock 120 is shown as an optional feature, and it can be additional backup choice to arrest or release movement of cable/rope/chain 108b, or its operation can be substituted entirely by any other suitable technological solution such as a RFID, mobile application, or a Bluetooth operated mechanism, or a wi-fi solution.
[35.] Figures 15a through 15e illustrate a fifth embodiment of the doorknob lock assembly. In this embodiment illustrated in Figure 15a through 15e, the inverted T-shaped sliding block 119 is replaced by a simple strong thin plate 144 that moves along 2 slidable grooves 145a and

145b, thereby reducing both the size and amount of material consumed, and making the entire assembly more compact to perform the same function.
[36.]Additianally, the objectives of using wheels 145a through 145d is to help in sliding the plate 144 with ease, and these wheels may either be replaced by ball-bearings, or other creative mechanism to cost-effectively achieve the purpose of movement of plate on the sliding grooves 145a and 145b with as little frictional loss as feasible. If ease of movement of sliding plate is achieved without wheels, the wheels may completely be dropped from the assembly design also.
[37.] Figure 16 shows a close-up view of stem 107 with cables. The stem edge has an extension that is arc-shaped 127 and it is designed to form a dose and tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob. The aim of all these stem edges is to improve the tamper-resisting ability to prevent the cable/rope/chain from becoming loose around the doorknob or from being removed from the doorknob.
[38.] Figure 17 shows another design where there is no extra protrusion around stem edge and for certain types and dimensions of doorknobs, this design may form a close and tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob.
[39.] Figures 18a and 18b shows another design where there is a small rectangular protrusion around stem edge and for certain types and dimensions of doorknob, this design may form a close and tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob. This rectangular protrusion may be suitable on certain straight-shaped doorknobs and this protrusion may help in arresting movement of cable/rope/chain, thereby preventing it from being removed from the doorknob and improving in its tamper-resisting ability.
[40.] Figure 19a and 19b shows another design where there is a parabolic and/or elliptical protrusion around stem edge and for certain types and dimensions of doorknob, this design may form a close and tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob. This shape of protrusion may be suitable on certain straight-shaped doorknobs and this protrusion may help in arresting movement of cable/rope, thereby preventing it from being removed from the doorknob.

[41.] Figure 20 shows another design where the protrusions around stem edge is pivoted at the center of the stem edge, wherein the protrusions are flexible to move around, and for certain types and dimensions of doorknob, this design may form a close and tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob,
[42.] Figure 21a shows another design where the stem 107 is bent so as to easily hang the doorknob lock assembly 101 vertically downward from the doorknob as shown in Figure 28h. A typical apartment may have a doorknob on the left or on the right side when one is facing the door, and so one may have a tight space on the left or right side of the doorknob, respectively. Also, a typical doorknob could be of circular type or straight-type. So: this design may be very useful as this stem 107 and doorknob lock assembly 101 is hanging vertically downward, and one do not have to be concerned about tight spaces on the left or right side of the doorknob.
[43.] Figures 21a through 21 d illustrate a stem design in which A-shaped stem edge is shown. In some cases and types of doorknobs, this may form a tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob.
[44.] Figures 22a through 22e illustrate a stem design in which V-shaped stem edge is shown. In some cases and types of doorknobs, this may form a tight loop of cable/rope/chain 108a and 108b around the neck of a doorknob. Figures 22f through 22j illustrate pictorially the use of chain that is not only strong and tamper-proof but that forms a very tight loop around the neck of the doorknob to illustrate the application. The part number of chain in these figures is marked as 154 to highlight its pictorial representations, although for all practical purposes it performs the role of 108a and 108b as illustrated and described elsewhere in other figures. Additionally, an optional chain handle 155 is also shown to illustrate that a mechanism like that may be installed to facilitate pulling of chain or cable while installing and uninstalling the stem assembly around the doorknob. In the example shown, A-shaped stem edge is utilized, although many other stem designs could potentially be utilized in a typical application.
[45.] Figure 23 is very similar to figure 2a through figure4. As shown in Figure 23 detail C, the cable/rope/chain 102 is broken into 2 pieces, and has a detachable lock and key mechanism in the middle. This cable detachment feature is provided so as to facilitate a particular user to exchange various sizes of parcel bags 103, such as extra-small, small, medium, large and extra-large, for the same doorknob lock assembly 101.

[46.] Figure 24a and figure 24b shows a magnified view of the cable detachment lock and key mechanism.
[47.] Figure 25a and figure 25b shows an optional embodiment in which the cable/rope/chain 108a and 108b are wrapped inside a tamper-resistant convex circular bead. This allows the cable/rope/chain 108a and 108b to be thin and flexible while at the same time it can be wrapped inside a stronger convex material such as a metal or other suitably strong material to give it significantly enhanced strength for tamper resistance. Although, a convex shaped circular bead is shown, we can use any kind of design or shape or geometry to accomplish the objectives indicated herein.
[48.] Figure 26a and figure 26b are very similar to that of Figures 25a-25b, except these have
concave shaped beads around the cable/rope/chain 108a and 108b. This allows the
cable/rope/chain 108a and 108b to be thin and flexible while at the same time it can be wrapped inside a stronger concave material such as a metal or other suitably strong material to give it significantly enhanced strength for tamper resistance. Although, a concave shaped circular bead is shown, other kinds of design or shape or geometry to accomplish the objectives indicated herein.
[49.] Figures 27a through 27d show a new embodiment of the doorknob lock assembly 101 wherein it is hanged vertically downward from the doorknob facing outward of the front door. The benefit of this design could be broad in some cases and situations wherein the space to the left or right side of the doorknob is limited and tight. By moving the doorknob lock assembly 101 from the side of the doorknob to below the doorknob, the tight space constraint is significantly reduced if not eliminated. An optional dangling arrestor 153 is also shown in this embodiment and the purpose of this is to offset the distance created between the curved stem and the door so as to avoid dangling of the doorknob lock assembly 101. It is important to note that dangling arrester 153 is NOT a mounting bracket of any sort and it is completely optional.
[SO.] Figure 28a through figure 28i shows and illustrates the various inner details and exploded views of many of doorknob lock assembly 101 and its essential components and parts. Almost all of the parts and components and their respective functions are already described earlier in other embodiments.
[51.] Figure 29a through 29c shows and illustrates how multiple-receptacle embodiment to receive multiple deliveries from multiple carriers can be achieved with our apparatus and

system. Essentially, the cable detachment system described in Figures 24a and 24b can be used repeatedly to connect one parcel bag to another until ones need for multiple deliveries are fulfilled. This design can be used with varying sizes of parcel bags. All parcel bags have a transparent message pouch that can be utilized to communicate specific delivery instruction to any mail carrier. Inclusion of the transparent message pouch on any parcel bag is an independent feature, and can be in all parcel bags irrespective of whether the delivery involves a single receptacle or multiple receptacles.
[52.] An example of a typical use of a primary embodiment is described below to help in understanding the application of this apparatus. This scenario is to provide a general understanding of a typical application and operation. It should be noted, that any real-world applications of the various embodiments can be significantly broader, and should not limited to the application described in this section.
[53.] There are 3 specific events that potentially take place while implementing the various embodiments to fulfill ones objective of receiving a parcel or delivery securely, and to eliminate or reduce the risk of losing one's parcel due to theft in front of one's front door. They are as follows:
1. Event 1: Actions of a parcel recipient or owner associated with setting up a parcel bag in front of one's apartment or place of stay to enable the receipt of parcel.
2. Event 2: Actions of a mail carrier while delivering, placing and securing the parcel inside the parcel bag at the time of delivery.
3. Event 3: Actions of the parcel recipient or owner collecting the package upon his/her return to his/her residence or business or place of stay.
Event 1: Setting up the parcel bag to enable receipt of a parcel
[54.] For circular (Figure 1a) or straight-shaped doorknob (Figure 1b), one needs to take a doorknob lock assembly (example Figure 5a), and extend or loosen the cable/rope/chain (108b). and wrap or loop it around the doorknob, and release the cable/rope/chain (108b) such that rope (108a and 108b) is securely tightened around the doorknob and cannot be removed from it. The lock (120) should securely engage in its position and should not allow the rope (123, 108b and 108a) to loosen from the doorknob. Either a physical or technological solution

(RFID, Bluetooth, mobile solutions or Wi-Fi) can be utilized to fulfill the function of a lock (120) and are described elsewhere in this document in greater detail. The parcel bag's zipper position (Figure 11a, 139) shall remain unzipped and the parcel bag shall be open, and should allow the delivery personnel to place the parcel inside the parcel bag. Additionally, the parcel bag lock (104) will remain unlocked at this juncture, but the parcel bag shall be securely connected to the doorknob lock assembly via cable/rope/chain (102).
[55.] Figure 2a, Figure 2b and Figure 2c illustrate the high-level overview of operations and the doorknob lock assembly involving a circular doorknob. Figure 3 illustrates the high-level overview of operations and doorknob lock assembly involving a straight doorknob. There are several embodiments of doorknob lock assembly and are described in detail in many figures elsewhere in this document.
[56.] Figure 4 gives a high-level overview for scenarios that involve securing the parcel bag to a door handle (Figure 1c). This operation is similar to that of circular or straight doorknob, but slightly different in nature. Figure 12a, Figure 12b and Figure 12c illustrates the usage nicely for a door handle. One needs to slide the rope with a circular metal ring (Figure 12a, 117) inside the door handle, and push the rope end (115) that has a lever (118) in it and lock it in position securely. Either the lock (Figure 4, detail A, 114) itself can be secured around the door handle as shown in Figure 4, Detail A, or the circular metal ring (117) of the Y-shaped cable (Figure 4, 113) can be slid inside the doorhandle, and into the lever (118), and can be securely locked by the lock (114). In other words, in the first option of lock 114, it will be as shown in Figure 4 Detail A. In the second option, the circular ring 117 will go through the door handle 112, and the lock 114 will cover only 117, and not cover the handle 112 inside the lever 118 as indicated. The rivet (115) on lock (114) ensures that the lock is always connected to the parcel bag securely. The parcel bag shall remain open (Figure 12a and Figure 12b) as shown and shall remain unlocked with zipper (139) in the open position.
Event 2: Receiving parcel or deliveries
[57.] When the delivery personnel arrive at the front-door, he puts the parcel inside the parcel bag (103), and moves the zipper 139 from its position in Figure 11a to its locked position shown in Figure 11b. The zipper 139 is securely locks into lock (104) in such a way that the zipper cannot be opened again unless one has the key for the lock (104) or knows the numerical combination of the lock. The lock can be of numerical combination type as shown in Figures

11a and Figure 11b, or any other type. Once locked, even the mail personnel shall not be able to open and access the parcel.
Event 3: Retrieving parcel or package
[58.] Upon return to one's residence, business or place of stay, the parcel recipient can use a key to open the doorknob lock (106 or 120) such that the lever (126) is rotated in such a fashion to allow movement of sliding block assembly (119), and loosening of rope (108b) to enable removal of the entire doorknob lock assembly and cable/rope/chain from the doorknob. Upon going inside one's residence or place of stay, one can unlock the parcel bag lock (104) and retrieve the contents of the parcel bag. In the door handle scenario illustrated in Figure 4, similar procedure can be performed to remove the cable/rope/chain (113) from the lock (114) and from the door handle (112).
