STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTNot applicable.
BACKGROUND OF THE INVENTIONThis invention relates generally to locking compartments and more specifically to an assembly that includes a compartment that is concealed when a key member is received within rotatable tumblers and related methods.
This section of this document is intended to introduce various aspects of art that may be related to various aspects of the present invention described and/or claimed below. This section provides background information to facilitate a better understanding of the various aspects of the present invention. It should be understood that the statements in this section of this document are to be read in this light, and not as admissions of prior art.
A recent book by Author Dan Brown, “The DaVinci Code” (hereinafter “the book”), has generated a renewed interest in mysteries and word puzzles. Featured in the book is a contraption referred to as a DaVinci Cryptex (hereinafter “the Cryptex”). As described, the Cryptex is a cylindrical assembly that is generally small enough to be manipulated within a person's hands and includes multiple rotating sections and a “key” that is removably receivable within the rotating sections. The exterior of each Cryptex section has the alphabet inscribed around its perimeter. Characters in the book are presented with a mystery/puzzle, the solution of which is a single word answer, presumably of a character length equal to the number of rotating sections in the Cryptex. The sections can be rotated so as to spell the correct word answer to the puzzle after which the key is removable from the lock which reveals the text of a new puzzle written on papyrus.
As the story in the book progresses, the characters go on an elaborate journey in search for clues regarding the correct answer word and, over time, ascertain the correct word which enables removal of the key. In the book, one of the Cryptex components forms a compartment in which an item (e.g., a second smaller Cryptex, a note, an item, etc.) can be concealed until the key is removed. In the book a message is written on a sheet of papyrus that is placed within the compartment.
In addition to the components above, the Cryptex in the book includes a glass vial of vinegar presumably within compartment that is designed and positioned with respect to the other Cryptex components to break if the Cryptex is forced open prior to the tumblers being aligned to spell the correct word answer. Vinegar apparently destroys papyrus and hence would destroy the message printed on the papyrus if spilled thereon. Thus, the characters in the book, in effect, get only one chance to open the Cryptex correctly.
While a Cryptex is an interesting contraption, the Cryptex described in the book has several shortcomings as a product for mainstream mystery and puzzle use. First, for a Cryptex like the one described in the book, the Cryptex is specifically designed for a single correct answer word and the Cryptex cannot be reused with other puzzles and associated answer words. A Cryptex that has only a single correct answer word can only be effectively used a single time with a specific person—once the answer word is determined by a person, the word is known and opening the Cryptex is no longer an interesting challenge.
Second, where separate Cryptex have only a single answer word, the cost of manufacturing the unique Cryptex would be relatively expensive. To this end, where there are 1000 separate puzzles and associated answers, 1000 differently configured Cryptex would have to be designed and manufactured—a costly proposition.
Third, as with most products that can only be effectively used once, where a Cryptex has only a single answer word, a maximum purchase price for most purchasers will typically be low. A low purchase price combined with the costs of manufacturing many different Cryptex configurations (i.e., a separate configuration for each puzzle and associated answer word) would make it difficult at best to make a profit in the Cryptex business.
Fourth, while the concept of destroying a message or item inside a Cryptex if the Cryptex is opened prior to spelling the correct answer word via the Cryptex tumblers is intriguing, using a breakable glass vinegar vial or the like is a messy and potentially dangerous solution which would not be acceptable to many potential purchasers.
Fifth, one of the interesting things about the journey to find clues to the correct word answer in the book is that an elaborate and automatically unfolding scheme is set up to yield the clues over time. In the book, the scheme generally involves activities independent of the Cryptex. While it would be extremely difficult to set up a scheme as elaborate as the one in the book, it would be advantageous if answer clues could be automatically presented over the course of a predetermined period thereby simulating a journey akin to the journey that occurs in the book. The Cryptex in the book is incapable of simulating a journey alone.
Sixth, in many cases a Cryptex user may want to come up with her own puzzle and answer word that may have a special meaning to the user and a person that receives the Cryptex. Here, where Cryptex are configured for use with a single answer word, personalized puzzles and answer words usually would not be supported.
Seventh, Cryptex like the one in the book require at least two people to be useful, a first person to design the mystery, craft the puzzle and the answer word and configure the Cryptex and a second person to receive the Cryptex and the puzzle and to solve the puzzle to reveal the contents of the compartment. In at least some cases it would be advantageous to have a system whereby a single person could use a Cryptex to play a mystery game.
Locking mechanisms have been designed for luggage and the like that include tumblers and a locking key received therein where the key is only removable when the tumblers are aligned in a specific orientation (e.g., so that a numeric code is aligned along an axis perpendicular to the tumblers). Here, in some cases, the mechanisms are designed so that the codes can be altered in some fashion. For instance, an exemplary locking mechanism includes a spring loaded configuration wherein, when the tumblers are in the unlocked position, a spring loaded member can be slid into a code setting position, the tumblers can be rotated until a new desired code is aligned and the spring loaded member can then be released.
While luggage type locking mechanisms are useful for locking luggage compartments or the like, luggage type locking mechanisms do not include a separate compartment that is concealed when the key is received within the tumblers and therefore are not suitable for use as a Cryptex. In addition, while a message or item could be placed inside a luggage compartment and locked therein via a luggage type lock, the resulting configuration and operation would not have the same appeal as a self contained Cryptex that can be held and manipulated in a users hands. Moreover, while codes can be altered in the case of some luggage type locking mechanisms, the length of the code cannot be altered in any known luggage type locking mechanism so that, even if. Furthermore, while spring type mechanisms have been designed for luggage locking mechanisms to modify codes, it is unclear how such mechanisms would be configured for use with a Cryptex that includes a concealed compartment.
Therefore it would be advantageous to have a Cryptex that can be used with more than a single puzzle and associated answer word. In addition, it would be advantageous to have a Cryptex wherein the answer word could be modified relatively easily and where a single person, in at least some cases, could use the Cryptex to play a puzzle game. Moreover, it would be advantageous to have a system wherein clues could be periodically provided to a Cryptex user thereby simulating a journey in search of clues.
BRIEF SUMMARY OF THE INVENTIONCertain aspects commensurate in scope with the originally claimed invention are set forth below. It should be understood that these aspects are presented merely to provide the reader with a brief summary of certain forms the invention might take and that these aspects are not intended to limit the scope of the invention. Indeed, the invention may encompass a variety of aspects that may not be set forth below.
It has been recognized that a Cryptex type assembly can be configured that includes both a retainer for a message or an item and a tumbler assembly where the tumblers can be manipulated to alter a correct answer word that enables a key to be removed from the tumblers. Thus, a Cryptex like assembly can be provided that can be used multiple times and with many different word puzzles.
It has also been recognized that an electronic Cryptex type assembly can be provided that includes a processor and a small display screen (e.g., LCD display, other flat panel technology, etc.) wherein a message may be displayed via the screen when the key is removed. In this case, the message stored for presentation via the display screen may be easily altered and, in at least some cases, could be modified over time.
In some embodiments of the present invention an exemplary Cryptex is a linear combination lock that is generally opaque or translucent so that its inner workings are not visible. The lock may include multiple rotating sections or tumblers with a fixed linear key that has a series of projecting pins along its length. Each tumbler may include a series of markings (e.g. the 26 characters of the alphabet or 10 digits) on the exterior wall(s) and a central hole through which the key passes to be locked in or removed when unlocked. In some cases the tumblers also have an enlarged countersunk hole or recess centered over the main hole. Here, the tumblers are sized in height to match the spacing of the pins in the key and the counter sunk holes are sized so that the tumblers can rotate freely around the projecting pins of the key. The tumblers may be in a cylindrical form, but other sectional shapes can be used as desired.
Each tumbler may also have a keyway cut radially from the center hole through to the countersunk hole. The keyways are sized to allow the projecting pins of the key to pass through the tumbler when properly aligned. In this manner when the tumblers are arranged according to a combination by orienting the markers in a pattern against a fixed alignment marker, the keyways are then all aligned in a row. The projecting pins of the key pass thru all of the keyways and the key is easily removed from the lock.
Besides having the rotating tumblers, in at least some embodiments the lock includes fixed top and bottom sections where one of the sections includes an alignment marker. The top and bottom sections are secured together so that when the key is in the lock and the lock is locked, the tumblers interfere with the key and the key cannot be removed from the lock. This can be done using external posts between the top and bottom sections or any of a variety of other fastening or joining methods. When posts are used, they can be glued, attached with threads and matching nuts (e.g. with tamper resistant or locking nuts), welded, or riveted to the top and bottom.
The top section may have a hole cut in it and a keyway (if the hole is not sized so the projecting pins can pass thru it) so the key can pass through it. The bottom section may generally be solid, although it can have a countersunk hole to prevent the key from moving laterally. In some embodiments, when the key is inserted into the hole, the key is restrained by a pin, flange, or gear teeth from rotating, so that the key maintains a fixed position relative to the lock.
In some cases the tumbler only has the center hole and the cut keyway, but not the countersunk hole for the pins of the lock. Instead a fixed spacing washer can be inserted between tumblers, the washer having a central hole sized to allow the key to be inserted and removed or to have a central hole and keyway positioned to align with the key and its projecting pins.
In some embodiments the key is designed so that it has a head that extends over the center hole and the keyway in the top section of the lock. The head prevents a user from sighting down the inside of the lock to crack its combination by looking for the keyways. In some cases the key head is sized so that it covers over any nuts or fasteners used with the posts to connect the top and bottom parts of the lock, providing protection against tampering with the nuts to open the lock.
To assist with aligning the tumbler sections, a ratchet or detente mechanism may be provided so that the external markings are easy to maintain in a chosen position and do not rotate spontaneously. One design for a ratchet mechanism is to provide small recesses or dimples spaced on the top of each tumbler according to the number and spacing of the external markings of the tumbler. The bottom surface of each tumbler forms one or more rounded bumps that extend outwardly. When stacked together the bump(s) of one tumbler naturally rest in one of the dimples of an adjacent tumbler. Just enough space is provided between the assembled tumblers so that when one tumbler is rotated its projecting tip(s) or bump(s) rise out of one dimple and naturally drop into the next dimple after partial rotation.
In some cases it is desirable that the pattern of letters that opens the lock be adjusted to another pattern (word). To do this, in a t least some cases, the lock is taken apart so the individual tumblers can be removed and separated from each other. To allow a user to change which letter on each tumbler is aligned with the keyway when the tumblers are in the unlocked orientation, the tumbler is composed of two pieces, an outer one and an inner one. The inner and outer pieces can be separated and the inner one rotated so the keyway is positioned to align with a new external letter or marking. The inner and outer pieces are then pressed together. To keep the two pieces properly oriented the inner and outer pieces may be in the shape or a regular polygon with the number of side equal to the number of markings on the perimeter of the outer piece of the tumbler. Alternately a series of matching gear teeth (the number of which equals the number of external markings) can be cut in the inner and outer pieces so they mesh together. Other positioning methods are anticipated, such as pins or one of the pieces can have a partial gear teeth cut into it, but not limited to these.
To secure the inner and outer sections together one of the sections may be undercut or have a ridge to keep the two sections together.
In some cases, it may be desirable to construct a Cryptex from highly valued materials such as wood, stone or metal. The machining of complex surfaces in such materials can be cost prohibitive. A tumbler composed of three pieces would allow changing letters on tumblers without requiring complex machining on the outer, visible portion of the tumbler. The previously mentioned inner and outer rings would become the inner and middle rings of a three ring arrangement. The inner and middle rings would operate as previously described. The outer ring can have a round, easily machined hole through its center, into which the outside of the middle ring is fit via any of a number of fastening techniques (e.g. pressure, adhesive). The combination of middle and outer rings then perform as the outer ring in the previous description.
When the Cryptex has provision for a seven letter word (forming a seven letter combination), but the word chosen to unlock it only has five letters, the lock is taken apart and the bottom two tumblers can be pinned together and to a non-rotating lock bottom section. In this example, the two bottom tumblers are aligned so that their keyways allow the key to be removed without further action. Preferably, when so aligned, the external markings include a space or blank “marking” that is aligned with the alignment marker on the top section or bottom section In this way a person using the Cryptex will know that the bottom two tumblers are not used.
Another method to accommodate shorter words is to assemble the lock with only 5 tumblers and to adjust the length of the linear key. One method of adjustment is to cut the key to the proper length, however this is not desirable as the key could not thereafter be used with longer words. Instead the key may be made in segments equal in length to the height of one of the tumblers. By removing two sections a key for 7 tumblers can be adjusted to fit a lock of five tumblers. Any method of adjusting the key length must ensure the key does not come apart when in or being removed from the lock and that the key or any section of it does not rotate in the lock.
Another Cryptex type embodiment includes a secret message associated with a key and incorporates the feature of allowing the key to be withdrawn when the tumblers are in any position. The secret message may be presented in this case on a display screen or the like when displayed. In this case, if the tumblers are not properly aligned to define the correct answer word when the key is removed, the secret message may be erased. Here, when the tumblers are properly aligned, the key is removable to reveal the secret message via the display.
In some electronic versions of Cryptex type assemblies the key may not have pins along its length. Instead the key may have an internal space to accommodate a circuit board including a processor, memory, power source, indicator, timer, a variety of sensors, and a communication port. Here, the memory of the key may be programmed with an external computer or PDA device with a message that is to be presented to the user via the indicator (e.g. a LCD display or a speaker) when the key is removed from the unlocked lock.
The tumblers in this embodiment may be arranged as before without the need for the countersunk holes. Instead the tumblers each may have an electrically conductive lead that passes through from the top to the bottom of the tumbler, e.g., from one ratchet dimple to the rounded projection below. The top and bottom sections of the lock have electrical contacts that are oriented to make contact with matching contacts on the key when the key is fully inserted. The top contact is connected to one of the ratchet rounded bumps for the top section and the bottom section contact is connected to one of its ratchet dimples. While the use of the ratchet mechanism is described, other provisions or areas for conducting electricity through the top and bottom sections and tumblers are anticipated.
When the tumblers are aligned so that the external markings match the pattern to unlock the lock a conductive pathway is established between the top section contact and the bottom section contact through every tumbler. The key has matching electrical contacts between the processor and the top and bottom section contacts. The processor may detect the presence of this conductive pathway and set an unlocked flag. The key also has a sensor to determine that it has been removed from the lock, for example using another set of electrical contacts, a switch, a photocell, etc. When the key is removed and the unlocked flag is set, the key may present the secret message via the display screen.
In the example here, whenever the tumblers are not properly aligned, the processor unsets the unlocked flag. If the key is removed while the flag is unset, the processor detecting the removal via its sensor for this purpose will not present the secret message via the indicator. Instead no message can be presented or one that indicates that the wrong word or pattern of markings was used when removing the key may be presented. If desired the key can also indicate that the key will become inert for a period time that the processor uses the timer to measure. The key can be reinserted in the lock, but the key will not respond and present any message other than a period of time that must pass before the next key removal will be confirmed (e.g. a day). In this manner, several tries can be made to guess the alignment pattern of the tumblers, but consecutive attempts are separated by periods. Using this design the user cannot determine what the correct alignment of the tumblers must be because the electrical contacts on the tumblers are hidden from view.
A sensor may be used by the key to determine if the lock is being disassembled. Upon detecting of this condition the processor can erase the secret code so that it will never be displayed.
If desired the key with projecting pins can also be used with the electronic lock, but in this case the key can only be removed when the tumblers have been properly oriented to unlock the lock. In this case the removal sensor is no longer needed, but the lock disassembly sensor can be used.
To prevent the key from being inadvertently removed from the lock before the tumblers are aligned as desired, a latch, spring, or interference ridge may be used. Here, to remove the key a user must press in the latch or spring thereby de-latching the key for removal.
In some cases it is desirable to purchase the Cryptex with a preprogrammed word as the alignment pattern for the tumblers. It is anticipated that the purchaser will select a Cryptex at a store or via the Internet with a preprogrammed answer word and an accompanying word puzzle, mystery, rhyme, or phrase whose solution or conclusion is the preprogrammed answer word. Typically the word puzzle is printed as part of a greeting card format that is given to the recipient of the Cryptex without the preprogrammed answer word printed on the card. The greeting card can be customized to include another message such as “Happy Birthday” or “Congratulation on Graduating”. Inside the Cryptex can be a second secret message, for example a location where a present can be found. The recipient then guesses the correct word or order of the external markings to open the Cryptex.
If the recipient fails to guess the correct word the person giving the Cryptex can provide other hints. To that end a Cryptex with a very challenging word may include more than one card so additional hints can be provided. Otherwise the original card can include an Internet web address where additional hints for this specific Cryptex are provided, for example a new hint every day or 8 hours.
In the case of an assembly where the unlocked position of the tumblers can be changed, suitable greeting cards with word puzzles and matching solution or answer words can be sold. In at least some cases it is contemplated that the answer word may be provided separate from the card. The purchaser of the assembly can buy the card, program the word into the assembly and give the assembly and the card with the word puzzle to a recipient to unlock.
Alternately, the owner of the Cryptex can review a list of puzzle questions on the Internet and purchase a greeting card with that question for download over the Internet (e.g. in a universal high quality image format such as the PDF format) to be printed on their printer. Additionally the text of the greeting card can be customized for the person to receive the Cryptex with their name or additional greeting message. The answer to the question is then provided for the purchaser/giver to retain. It may be desirable in this type of commerce that the puzzle question and the answer are not provided at the same time until a purchase has been made, otherwise the owner of the Cryptex may print the question and the answer without payment.
In some cases an answer word may be proved and the user may select a difficulty level for the puzzle question. When a purchase is made the puzzle question can be sent to over the Internet in a greeting card format that can be customize by the purchaser.
In other cases the Internet can be used to purchase a Cryptex where the puzzle question and answer is either specified and entered by the purchaser or selected from previously created questions and answers. The purchaser is then shipped an assembled Cryptex that is unlocked using the specified answer, a matching greeting card, and the answer on a separate piece of paper for retention. If desired the answer can be retained on the Internet site providing the Cryptex.
In at least some cases an external display screen or an audio output mechanism may be provided on at least one of the assembly components for providing periodic clues to an assembly user regarding the correct answer word. In addition, in at lest some cases, the external display screen may be used to provide the message when the key is successfully removed from the tumblers.
In some embodiments it is contemplated that a USB or a wireless system may be used to transmit new answer words to electronic Cryptex type assemblies wherein assembly processors could then modify the correct answer words associated therewith. Thereafter, a puzzle could be e-mailed or otherwise provided to a user of the assembly so that the user could play a word game independent of other users.
These and other objects, advantages and aspects of the invention will become apparent from the following description. In the description, reference is made to the accompanying drawings which form a part hereof, and in which there is shown a preferred embodiment of the invention. Such embodiment does not necessarily represent the full scope of the invention and reference is made therefore, to the claims herein for interpreting the scope of the invention.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGSThe invention will hereafter be described with reference to the accompanying drawings, wherein like reference numerals denote like elements, and:
One or more specific embodiments of the present invention will be described below. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
The present invention relates to the construction, programming and purchase of a Cryptex type assembly 80 (see
Cryptex 80 shown in
Below top section 102 is an optional spacer 110 (see
Top section 102 forms a central opening 150 that is aligned with axis 300 when section 102 is stacked at one end of the tumbler stack. In addition, section 102 forms a keyway 152 that extends laterally from opening 150. A hole 157 is formed in a top surface (not labeled) of top section 102 adjacent opening 150.
In the illustrated embodiment, each of spacers 110 and 112 form a central opening 354 and 356, respectively, and spacer 110 forms a keyway 156. Bottom section 104 forms a central countersink hole, recess or opening 158. As illustrated, when sections 102 and 104, spacers 110 and 112 and tumblers 114 are stacked together, the components form a tumbler channel 360 (see
Between top 102 and bottom 104 sections are a series of rotating tumblers 114 which can be circular or multi-sided in plan view. Tumblers 114 are arranged in a stack about tumbler axis 350. Each of the tumblers is similarly constructed and operates in a similar fashion in at least some embodiments and therefore, unless indicated otherwise and in the interest of simplifying this explanation, only one of tumblers 114 will be described here in detail.
Referring to
Each tumbler has a top (i.e., first) surface 118 (see
Vertical keyway, recess or gap 124 extends laterally from opening 123 and stops short of external wall 117. Cut into bottom surface 120 is a countersunk hole or opening 126 that has the same center line as opening 123 and a radius generally equal to the distance from the center of tumbler 114 to the distal end of keyway or gap 124. Openings 123 and 126 come together at a ridge and form a tumbler coupler or collar where gap 124 extends through a portion of the collar.
Optionally, tumblers 114 can have a detent feature or ratchet mechanism to help an assembly user keep tumblers 114 aligned after rotation. The detent mechanism is provided such that the separate tumblers 114 rotate more readily when indicia thereon is misaligned with markers 113 than when the indicia is aligned with the markers 113. Thus, for instance, assuming six equispaced letters arranged about external surface 117, if a first letter is aligned with marker 113, initially the detent feature will impede rotation of the tumbler but, after rotation through a small angle (e.g., 5°), rotation will be relatively easy until the next adjacent letter is aligned with marker 113 (i.e., after 60° of rotation). In at least some embodiments the ratchet mechanism includes one or more dimples or recessions 128 arranged on top surface 118 so as not to interfere with keyway 124. The dimples are arranged to correspond to indicia 116, so if there are 26 markers uniformly spaced on tumbler 114 there may be 26 matching dimples. The top surface of bottom spacer 112 also includes recessions 128.

An alignment pin 154 extends from head member 132 in the same direction as shaft member 134 and is spaced apart from shaft 134 to be aligned with, and is sized to be received within, hole 157, when shaft member 134 is received and passes through opening 150. Pin 154 and hole 157 cooperate to restrict/prevent rotation of key 84 with respect to top section 102. Other methods of preventing key 84 from rotating are contemplated such as rotation restrictors, gear teeth, flanges, or first and second stop surfaces in lock 82 and key 84 that interact with each other to prevent rotation of key 84.
Referring to
Referring to
Shaft 134 is receivable within channel 360 so that each tumbler coupler is matched to a key coupler, forming a coupler pair. To insert key 84 into the stack, keyways 124 of each tumbler are oriented so as to be in a line so projecting pins 140 can pass through the keyways 124 and so alignment pin 154 can enter hole 157. Keyways 152 and/or 156 must also be aligned with keyways 124. To prevent key 84 from moving laterally, countersunk hole or opening 158 in bottom section 104 is provided and receives the distal end of shaft member 134. The position of the external markings or indicia 116 for each tumbler 114 relative to alignment markers 113 when the keyways are aligned corresponds to the secret code or answer word 88 that is used to unlock lock 82.
When key 84 is fully inserted, underside 136 of head member 132 completely covers opening 150 and keyway 152 so that it is not possible to peer into lock 82 to discern the positions of the keyways 124. In some cases head member 132 is arranged so as to cover any mating devices 108 (see
To lock Cryptex 80, with shaft 134 received in channel 360 one or more of the tumblers 14 are rotated. Openings 126 of each tumbler 114 are sufficiently sized that pins therein can pass when the tumbler is rotated. When locked, key 84 cannot be removed from lock 82 as one or more pins 140 are blocked by tumblers 114 whose keyways or gaps 124 are not axially aligned with associated pins. When locked, answer word 88 is not obvious to the recipient.
When Cryptex 80 is assembled and locked and when ratchet recessions 128 and raised members 129 are used, just enough room is provided between top section 102 and bottom section 104 so that one tumbler 114 at a time can be rotated with respect to adjacent tumblers. When one tumbler 114 is rotated, the recessions 128 and raised members 129 of the rotating tumbler 114 and a tumblers 114 (or top spacer 110 or bottom spacer 112) adjacent the rotating tumbler disengage until the tumbler 114 is rotated enough to allow the recessions 128 and raised members 129 to again align. Once the recessions and raised members re-align, the raised members snap or spring into the next set of recessions 128 of the adjacent tumblers 114.
When lock 82 is unlocked and key 84 is removed, the message associated with indicator or retainer 160 is accessible or provided. The secret message can be another puzzle or mystery (e.g. a puzzle that, when solved, informs the recipient of the location of a gift). However, the message may be a simple text statement and not a puzzle. In some cases a physical item, object or gift (e.g. bracelet, money, gift certificate, or candy) may be hidden inside chamber or compartment 164 (see
Alternate Cryptex Embodiment
Alternate Tumbler Design
The alignment of tumblers to unlock a Cryptex can be established and fixed when the Cryptex is manufactured. However, in some instances, it will be desirable for a purchaser of a Cryptex to be able to change the unlocking alignment of the tumblers so that the answer word 88 associated with the Cryptex can be altered. To accomplish this task, a modifiable tumbler configuration is contemplated wherein the relative juxtaposition between the tumbler coupler (e.g., the gap) and the indicia on the external surface of the tumbler is alterable.
Referring still to
Another modifiable tumbler 114b configuration is illustrated in
Referring to
Internal member 172b includes an external surface 178b, an internal surface 125b and top and bottom surfaces that are not labeled. External surface 178b is shaped to mirror and to mate with internal surface 175b of external member 170b in any of several different orientations where surfaces 175b and 178b restrict rotation of member 172b with respect to member 170b in each of the different orientations. For instance, as illustrated, each of internal surface 175b and external surface 178b may include ten flat subsurfaces displaced about a central axis so that ten different relative orientations are possible. Internal surface 125b forms a collar and gap 124b akin to the similar components illustrated in
Referring to FIGS. 13 to 15, one additional modifiable tumbler configuration 114d is illustrated where features similar to those described above are identified via the same number followed by a lower case “d”. In
Removable marking strip 184d is shown in
Tumblers Combined with Spacers
In at least some embodiments it is contemplated that stationary spacers may be provided between adjacent tumblers. To this end, an exemplary Cryptex configuration 80e is illustrated in
Varying Answer Word Length
In at lease some embodiments, it is contemplated that a Cryptex user may want to use a Cryptex with answer words having more than a single length (e.g., one time an answer word may include 5 characters and a following time the word may include 7 characters). Here, the present invention contemplates several mechanical solutions for altering the length or at least the effective length of an answer word. First, referring again to
When the number of tumblers is altered, the key length must likewise be modified. To this end, referring to
Second, in some embodiments, end tumblers may be lockable so that they do not rotate about the tumbler axis, thereby reducing the effective length of the answer word. To this end, referring again to
Shaft segments 195e and end piece 196e must be connected to each other so they do not separate due to twisting or when key 84e is pulled or pushed. One method of connecting segments 195e and end piece 196e together is to place a horizontal male dovetail at the top of each segment that mates with a horizontal female dovetail in shaft 134e or an adjacent segment 195e. Other methods of attaching segment 195e and shaft 134e are anticipated such as screws, pins, glue, etc.
When adding or removing tumblers 114e, it may also be necessary to lengthen, shorten, or replace connectors 106e. This may be expedited when individual spacers 187e are used with individual connectors 106, so they can be added as sets for every tumbler 114e added (see
Tumbler Grain Matching
Electronic Embodiments
Externally, Cryptex 80f has an appearance that is similar to the previous embodiments. To prevent accidental removal of key 84f from the channel formed by tumblers 114f, a latching mechanism 200f is provided. In one embodiment, latching mechanism 200f is part of head member 132f of key 84f and consists of a button 202f connected to a latch 203f. Button 202f and latch 203f are forcibly extended by spring 204f. When key 84f, is placed in lock 82f latch 203f is pressed into recess 206f of top section 102f. Key 84f can only be removed when button 202f is depressed to disengage latch 203f from recess 206f. Other means of securing or latching key 84f to lock 82f are anticipated including without limitation snaps, friction, bolts, screws, pins, tape, wedges, etc.
Key 84f includes an internal space 208f that houses a circuit board 210f and no longer includes pins 140. Circuit board 210f is used to arrange the electronic components show in
When key 84f is inserted into lock 82f, key removal sensor 254f detects that the key is in the lock channel. This can be done by passing a current between contacts 212f and 214f and fixed contacts 220f and 222f of top 102f or spacer 110f. When there is a closed circuit, key 84f is in the channel. Key removal sensor 254f can instead be linked to latching mechanism 200f so that it is activated when latch 203f is retracted allowing key 84f to be removed.
Tumbler alignment sensor 256f can be constructed using a fixed contact 220f which is further linked to conductor 232f that goes to one of raised members 129 of spacer 110f. Each tumbler 114f also has a single conductor 236f between one recession 128f and a raised member 129f there below. Finally, another fixed conductor 236f is placed in one dimple of bottom spacer 12f. Conductor 236f terminates at contact 238f. When key 84f is in the channel contact 240f is in electrical contact with contact 238f.
Fixed conductors 232f and 236f are aligned so that they are in a direct vertical line above each other. The conductors 234f of tumblers 114f are arranged so that when the tumblers 114f are in any locked position, the tumblers are not all making contact with each other or with conductors 232f and 236f. Only when tumblers 114f are aligned in the unlocked position is a circuit made between contracts 212f and 220f, conductor 232f, conductors 234f, conductor 236f, and contacts 238f and 240f, together acting as an alignment sensor 256f, through processor 250f.
When lock 82f is unlocked, processor 250f detects the unlocked condition and sets an electronic unlock flag. When any of the tumblers 114f are moved, processor 250f unsets the unlock flag. When key 84f is removed from lock 82f, processor 250f detects the removal and checks the unlock flag. When the flag is set, processor 250f activates indicator 160f to present a secret message. When the flag is not set, the processor 250f does not activate the indicator 160f or uses it to present a message indicating tumblers 114f were not aligned so as to unlock lock 82f. Processor 250f, in this case, may then activate timer 260f to force a time delay before another key 84f removal will result in the indicator 160f being activated. For example it may be desired after key 84f has been removed once prior to using the tumblers to indicate the correct answer word, that the user must wait for 10 minutes before the next removal will be checked to determine if lock 82f is unlocked. Key 84f removal prior to 10 minutes can result in indicator 160f presenting a message that more time must pass before unlocking will be detected. Various timing strategies are anticipated, such as lengthening or shortening the time before the next unlock attempt will be validated.
It is further anticipated that key 84f can be extended as described above where shaft segments and an end piece can be added so as to maintain the conductive path described for alignment sensor 256f (see again
In at least some embodiments it is contemplated that the secret message presented via indicator 160f may be programmed by a separate computer (e.g. a personal computer, cell phone, or PDA) that has a communication port compatible with key communication port 262f (not separately shown in
In some cases processor 250f, power source 252f, indicator 160f, and other components of circuit board 210f may be part of lock 82f instead of key 84f, for example see indicator 160f in
In some cases it may be desirable to place an additional disassembly sensor 264f in key 84f. Referring again to
While conductors 236f are shown placed between a recession 128f and a raised member 129f of tumbler 114f, the conductors can be placed elsewhere and no ratchet mechanism need be provided. Furthermore it is anticipated that other sensors can be used by key 84f to determine when tumblers 114f have be placed in the unlocked position (e.g. by using a sensor along key 84f for each tumbler 114f). The sensors need not use contacts and, instead, can be magnetic, optical, or other non-contact sensors.
It is also anticipated that other type of sensing technology can be used for removal sensor 254, alignment sensor 256, and disassembly sensor 264 other than electrically conductive sensors. Other sensors include, without limitation, optics, fiber optics, buttons, switches, resistors, capacitors, and magnets.
As in the case of the mechanical Cryptex assemblies described above, in some cases it may be desirable to alter a Cryptex answer words. Referring now to
When key 84g is in channel 360g processor 250g is placed in a programming mode by programming activator 272g which may be an external button or a radio receiver. When the programming activator is activated (e.g., pressing a button or receiving a programming radio signal), processor 250g senses the resistance value for each tumbler 114f using tumbler position sensor 266g and places the value in memory 251g. During subsequent use, processor 250g determines that lock 82g is unlocked when the same resistance values are measured for each tumbler 114g as stored in memory 251g and sets the unlock flag. Any other resistance values correspond to a locked position.
Tumbler position sensor 266g can sense other physical traits beside resistance, for example capacitance or reflected light color.
When the resistance values corresponding to each indicia 116g are known, processor 250g can be programmed when key 84g is not in lock 82g. Programming activator 272g may include communication port 262g in the form of a linking device or connector (e.g., a USB connector) linked to processor 250g or via a radio frequency link (e.g. Bluetooth or 802.11b). Communication port 262g receives a programming signal from an external computer using a second linking device (e.g., a matching USB connector or radio frequency link) with the resistance values for each tumbler 114g and sends it to processor 250g to store in memory 251g. In this manner the sequence of markings that are used to unlock lock 82f can readily be provided by external programming as discussed in additional detail below.
Referring again to
Compartment lock 274f can follow the same rules described above for activating indicator 160f. That is, if key 84f is removed when lock 82f is locked, compartment lock 274f can remain secured for a period of time (e.g. 1 hour) before it can be attempted to be unlocked again. When key 84f is removed and lock 82f is in the unlocked position, compartment lock 274f may be deactivated allowing access to the compartment. In some cases, compartment lock 274f is arranged to prevent key 84f from being removed from lock 82f until tumblers 114f are in the unlocked position.
Cryptex 80f can also provide additional hints, clue(s), or word puzzles to assist in discovering the answer word. A clue can either be a new word puzzle or can be a descriptor of the answer word (e.g. “it starts with a S”, “it isn't a rock”). Clues can be presented using indicator 160f when the indicator is visible or audible outside of Cryptex 80f. For example, the word puzzles can be presented over a period of time or vary by the number of attempted removals of key 84f from lock 82f.
Referring again to
Word puzzles can also be stored in a key memory and can be presented using an externally mounted indicator where the process of presenting word puzzles can be understood by a person who has not unlocked the Cryptex or removed the key. This can be done by using a display 160h that is mounted on the exterior of a Cryptex as seen in
Cryptex Purchasing
It is anticipated that one particularly useful way to sell Cryptex will be at a store as part of a novelty item or gift set 300. To this end, an exemplary gift set 300 is illustrated in
Greeting card 90 can have a printed exterior greeting message 312 and/or graphic image 313 and/or an interior greeting message 314 as well as the word puzzle 86. When desired, card 90 will also include an Internet address 316 (e.g., printed on the back of card 90) where additional clues, hints or puzzle questions can be found related to answer word 88 for the specific Cryptex 80. This can be of great help when the recipient cannot solve the puzzle question and unlock Cryptex 80. The additional clues or hints can be provided as a single web page or as a series of hints that change over time so that more assistance is available but not all at once. This can also be done by changing the hint each time the person uses a browser to get a hint by using a cookie to determine the number and time of visits. Furthermore, a timer may be used to prevent the person from getting all of the hints too quickly (e.g., one per day). Additional hints can be printed and provided in box 302 and given to the recipient over time at the discretion of the purchaser/giver. Graphic image 313 can also relate to word puzzle 86 and answer word 88. For example, in some cases, answer word 88 can be an object either in or in some cases missing from image 313.
When Cryptex 80 and card 90 are given to a recipient, the purchaser/giver retains the printed answer card 308. In some cases, printed answer card 308 is not provided and answer word 88 is not printed on box 302. In this case, Cryptex 80 is unlocked only via solving word puzzle 86, with or without Internet provided hints.
While set 300 includes box 302, it is anticipated that set 300 may not include box 302. For example, a blister pack, bag, or other means may be provided to keep Cryptex 80, greeting card 90 and printed answer card 308 (when provided) from being separated before purchase.
Cryptex 80, when equipped with tumblers 114 that allow the alignment of keyway 124 to be changed, can also be purchased without the remaining parts of set 300. In this case, the purchaser will provide a greeting card of their own, for example, with the word puzzle 86 created and printed by the purchaser and the answer word 88 being a secret to the purchaser. By modifying the alignment of keyways 124 in tumblers 114, Cryptex 80 can be unlocked using the purchaser's self chosen answer word 88. As previously described, Cryptex 80 can have one or more lower tumblers 114 restrained to accommodate short answer words 88 or tumblers can be added or removed from lock 82 and segments 195 to key 84 to accommodate answer words of various lengths.
In other cases where Cryptex 80 can be modified by a purchaser to accommodate different answer words 88, greeting card 90 with printed word puzzle 86 and matching printed answer card 308 can be purchased together, but separate from Cryptex 80. The purchaser then rearranges keyways 124 so that when external indicia 116 match the answer word 88, key 84 can be removed from lock 82.
In some cases, set 300 is comprised only of Cryptex 80, which can be reprogrammed, and greeting card 90, which is blank. In this case, lock 82 and key 84 may be separated or the markings lined up to a default unlocked setting (e.g., all “A” characters). The purchaser creates their own word puzzle 86 and answer word 88. The purchaser programs lock 82 so that tumblers 114 are in the unlocked position when the selected answer word 88 is aligned with markers 113. The user uses a retail self service station or kiosk or their own computer with a user interface or display 320, a selection indicator (e.g. a mouse, keyboard, or voice recognizer) and a printer to print a word puzzle 86 and any other greeting or image 313 on card 90. The computer can also be used to program a hidden message via a processor to be displayed via an indicator. The retailer kiosk can also provide the user with choices of greeting messages 312 or 314 and images 313.
It is possible to purchase greeting card 90 via an Internet commerce site. This site can display a list of word puzzles 86 on a computer interface or display 320 as shown in
In this case tumblers 114g can be considered to be an input device and communication port 262g can be considered an answer word setting device when used with an external computer and interface 320g.
It is also possible to let the user select the answer word 88 first for purchase and then display an associated word puzzle 86. In either case, the purchaser is not shown both word puzzle 86 and answer word 88 prior to purchasing the combination.
Varying Tumbler Arrangement For a Specific Answer Word
When individual tumblers can be added or removed, when tumblers can be restrained from rotating (e.g. using pin 190), or a tumbler is composed of an external member and an internal member, instructions can be provided to assist in modifying a Cryptex 80 based on a specific answer word that is selected. For example, referring again to
To modify the Cryptex answer word, a specific answer word is selected (e.g., at a retailer Kiosk or using an internet browser). Software then determines an arrangement of the external member 170b versus the internal member 172b for each tumbler 114b, so that when the tumblers 114b are arranged with the answer word aligned with alignment marks 113b, the Cryptex is unlocked. This can be aided by placing a different numeric designation on each or the four different tumblers 114b. The instructions can then indicate that the tumblers are to be stacked in an order corresponding to tumbler numeric designations 3, 2, 2, 1, 1, 2, 1.
As a further aid, external member 170b can have a numeric designation imprinted on its top surface 118b corresponding to each indicia 116b. By further designating this number, an inner piece can be rotated or positioned so that keyway 124b is aligned with a specific one of the numbers on the external member and hence with a specific one of the letters. The instructions to configure a Cryptex 80b that unlocks using a selected answer word would then appear as instructions to arrange external members 170 and internal members 172 in the following order. 3-5, 2-7, 2-1, 4-4, 1-6, 2-8,1-4, where the first number indicates one of the three different tumbler types and the second number in each pair indicates how the inner and outer members should be aligned.
In some cases the instructions may include information to pin or restrain a specific tumbler so that it cannot rotate. In other cases the instructions may indicate specific tumblers that should be purchased to build a Cryptex 80 that unlocks using a specific answer word. Purchasing of additional tumblers may be essential when tumblers are not composed of external members and internal members or otherwise adjustable.
In some cases, tumblers 114 are selected so that, when arranged in a specified order, they can be aligned with alignment marker 113 to spell a large variety of English or other words even if the words are not the specific answer word that could unlock the assembly. In some cases the words are selected so they could also be possible, but not perfect or intended, solutions to an associated word puzzle.
While the invention may be susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and have been described in detail herein. However, it should be understood that the invention is not intended to be limited to the particular forms disclosed. For example, in some cases alignment pin 154 and hole 157 may not be required. In addition, in some cases marks 113 may not be provided
Thus, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the following appended claims.
To apprise the public of the scope of this invention, the following claims are made:
