Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to a locking mechanism adapted to be opened by the use of a quick tactile releasing combination.




2. Description of the Prior Art




Security in this day and age is a necessity. Most items the average citizen possesses require security measures to protect these items from unscrupulous persons. The desire to protect one's possessions necessitates the use of locks. Most conventional locks require the use of use either a key or an alpha-numeric combination in order to open the locks.




Keyed locks require the maintenance of the key itself. Without the key, the lock does not open. Obviously, keys can be lost, broken, or stolen. All of these circumstances defeat the purpose of using a lock to secure items so that only the owner can access the items.




Combination locks use a different locking philosophy to avoid the pitfalls of locks requiring keys to facilitate their operation. The conventional combination lock requires a user to memorize alpha-numeric characters and to visually confirm the alpha-numeric combination entered on the lock in order to release the lock from the items it secures. This requires a line of sight to the alpha-numeric controls on the lock, comprehension of the alpha-numeric characters on the lock, and adequate light in order to read the alpha-numeric characters on the lock. Without this visual confirmation, a user of a conventional combination lock will fail to enter the correct alpha-numeric combination and be unable to open the lock. Thus, there is a need in the art for a tactile releasing lock adapted to open without visual confirmation of the locking combination or the use of an independent key.




With the afore mentioned focus on security, the number of households having firearms as a means of protection has increased. The inherit danger of firearm necessitates a safe apparatus in which to secure a firearm from children and other unauthorized users. Also, since the need for a firearm around the home usually arises at night when the probability of potential intruders increases, a proper firearm lock needs to have releasing features that operate in the absences of adequate light or in situations when the view of the lock is obstructed.




The use of a lock accessed by a key to secure a firearm negates one of the prime purposes of using a lock to secure a firearm—to protect unauthorized access to and use of the firearm. For example, if the key to a lock is kept in the home, there is a potential risk of an unauthorized person, especially a child, gaining access to the firearm by discovering the location of both the locked firearm and the key. Also, the use of an independent key to release a lock runs a high risk of losing the independent key, which is the only method by which to open the lock. Thus, the potential risk of unauthorized access to a keyed lock combined with the probability of misplacement of the key that opens the lock makes the use of a keyed lock to secure a firearm undesirable.




A conventional combination lock is also undesirable to secure a firearm since visual confirmation of the lock is needed to correctly input the combination of alph-anumeric characters required to open such a lock. For example, U.S. Pat. No. 5,720,193 issued to Dick is a typical push button firearm lock. The Dick lock requires a user to press the correct combination of alpha-numeric characters associated with numerous release buttons. The correct sequence of alpha-numeric buttons must be activated in order to release the Dick lock. This alpha-numeric combination entry requires a user to read and comprehend either a series of alpha-numeric characters or other symbols. Without adequate lighting or a line of sight to the lock this task is very difficult, if not impossible, to perform.




U.S. Pat. No. D393,305 issued to Mizner is a typical combination lock operated through the use of rotational dials with numerical indices as the releasing mechanisms for the lock. A user of the Mizner lock must visually confirm the correct numeric combination in order to open the lock. Once again, this requires a line of sight to the lock and adequate lighting to read the characters on the releasing mechanisms.




Other firearm locks use different forms of alpha-numeric opening mechanisms in order to release the locking apparatuses. No other lock, however, operates solely through tactile manipulation.




Once again with the afore mentioned focus on security, one needed feature of a proper firearm lock used in households is the rapid release of the lock from the firearm. This requirement stems from the urgency required in situations when a firearm is used in the home. Namely, a firearm lock that requires any appreciable amount of time to open increases the potential danger to the homeowner. This increase occurs due to the rapid unfolding of events during a burglary of the home when precious seconds can mean life or death.




Thus, there is a need in the art for a quick tactile releasing lock adapted to secure a firearm and to open without visual confirmation of the locking combination or the use of an independent key.




SUMMARY OF THE INVENTION




The present invention provides a locking device designed to open by tactile manipulation without visual confirmation of the locking combination. This device comprises a housing, a securing element, and a plurality of tumbling levers located inside the housing. Each tumbling lever is located in a plane of movement parallel to other planes of movements of the other tumbling levers. Also, each tumbling lever includes a tactile engagement surface and each tumbling lever engages the securing element so that movement of a tactile engagement surface disengages the corresponding tumbling lever from the securing element.




A method for releasing an item from a locking device is also disclosed. This method includes steps of providing a tactile releasing lock engaging the item. The method teaches manipulating, without visual confirmation, the tactile releasing lock to free the item. The method teaches that the correct manipulation of tactical releasing surfaces on the locking device releases the locking device from the item. The method also includes the use of a releasing mechanism which separates the tactile releasing lock from an item it secures once the correct manipulation of the tactile releasing surfaces on the releasing lock has been performed.




It is a general object of the present invention to provide a quick release tactile locking device adapted to open without visual confirmation of the releasing combination.




Another objective of this quick tactile release lock is to allow an owner of a firearm to have peace of mind that the firearm is secure, yet have the ability to rapidly operate the locking device, without visual confirmation, to release the firearm secured by the locking device.




Further, it is desired that the operation of this lock allows quick access to the normal firing position of a firearm. As a result, another object of the present locking invention is to conform the design of the lock to the shape of a firearm and allow manipulation of the tactile releasing surfaces and separation of the lock from the firearm while the operator's hands are near the normal firing position used to discharge a firearm. This facilitates an expedient deployment of a firearm.




Still another object of this invention is to provide a method in which a locking device opens without requiring visual confirmation of the releasing combination.











Numerous other objects, features and advantages of the present invention will be readily apparent to those skilled in the art, upon a reading of the following disclosure, when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring now to

FIG. 1

, the locking device of the present invention is shown and is generally designated by the numeral


10


. The locking device


10


is a device for securing an item


12


. The locking device


10


comprises a housing


14


, a securing element


16


and a plurality of tumbling levers


18


located inside the housing


14


. Each tumbling lever


18


is located in a plane of movement


20


parallel to the other planes of movement


20


of the other tumbling levers


18


and each tumbling lever


18


includes a tactile engagement surface


22


. Each tumbling lever


18


engages the securing element


16


such that the interaction between each tumbling lever


18


and the securing element


16


maintains the locking device


10


in a secured and locked position. The locking device


10


is designed so that movement of each tumbling lever


18


disengages that tumbling lever


18


from the securing element


16


, thereby allowing the locking device


10


to release the item


12


it secures.




The housing


14


has access openings


72


through which the tactile engagement surfaces


22


protrude. The housing


14


has the number of access openings


72


to correspond to the number of tactile engagement surfaces


22


on tumbling levers


18


. One access opening


72


corresponds with each tumbling lever


18


and allows a human user of the locking device


10


to manipulate the tactile engagement surfaces


22


to disengage the tumbling lever


18


from the securing element


16


. The disengagement is the adjustment of the tumbling levers


18


to align the detent portion


24


of the tumbling levers


18


with the locking discs


30


of the securing element


16


. This alignment releases the locking device


10


from the item


12


.




In the locked position, the securing element


16


penetrates the housing


14


and engages the tumbling levers


18


. Each tumbling lever


18


includes a detent portion


24


engaging the securing element


16


when the locking device


10


is in the locked position. Manipulation of the tactile engagement surface


22


of an associated tumbling lever


18


repositions that tumbling lever


18


and thereby disengages the detent portion


24


of that tumbling lever


18


from the securing element


16


.




The securing element


16


, which can also be described as a lock bolt


16


, includes a connection section


26


. The lock bolt opening


28


in the housing


14


is geometrically shaped to accept the connection section


26


of the securing element


16


, including the locking discs


30


on the connection section


26


of the securing element


16


. Once the connection section


26


penetrates the lock bolt opening


28


, the detent portion


24


of each tumbling lever


18


engages the connection section


26


of the securing element


16


. In a preferred embodiment of the invention, the connection section


26


of the securing element


16


has four locking discs


30


, indicated as


30


A,


30


B,


30


C, and


30


D in FIG.


6


. In alternate embodiments, the number of locking discs


3


C will increase as the need for incorrect combinations of the lock


10


will increase as well as the physical capacity of the housing


14


increases. Also, the locking discs


30


are separated by spacing stems


31


, indicated as the


31


A,


31


B,


31


C, and


31


D.




The engagement between the locking discs


30


, spacing stems


31


, and the detent portions


24


of each tumbling lever


18


controls the securing and releasing characteristics of the locking device


10


. For example, in a preferred embodiment, the locking device


10


includes four tumbling levers


18


, indicated as


18


A,


18


B,


18


C, and


18


D, in

FIG. 6 and 7

. In this preferred embodiment, the number of tumbling levers


18


correspond to the number of locking discs


30


. Also, the geometric configurations of the locking discs


30


correspond to the geometric configurations of the detent portions


24


of the tumbling levers


18


. In order for securing element


16


to fully penetrate the locked bolt opening


28


in the housing


14


and secure the item


12


, the connection section


26


of the securing element


16


must pass through the detent portions


24


on each of the tumbling levers


18


.




As connection section


26


begins to penetrate the lock bolt opening


28


, locking disc


30


D is the first locking disc


30


to engage a tumbling lever


18


. In order for locking device


10


to secure the item


12


, locking disc


30


D must pass through each of the detent portions


24


of the tumbling levers


18


. This requirement necessitates that detent portions


24


A,


24


B,


24


C, and


24


D, shown in

FIG. 6

, each have both the geometrical configuration and alignment to allow locking disc


30


D to penetrate into the housing


14


. In similar fashion, the next locking disc


30


to penetrate the lock bolt opening


28


is locking disc


30


C. Locking disc


30


C must pass through detent


24


A,


24


B, and


24


C on tumbling levers


18


A,


18


B, and


18


C, respectively. Once again, the geometric configuration and alignment of detent portion


24


A,


24


B, and


24


C allow locking disc


30


C to penetrate the housing


14


when the locking device


10


is correctly manipulated during the securement of the item


12


.




Similarly, locking disc


30


B must pass through detent portions


24


A and


24


B located on tumbling levers


18


A and


18


B, respectively. This necessitates detent portions


24


A and


24


B to be geometrically configured and aligned to allow locking disc


30


B to pass. Finally, locking disc


30


A must pass through detent portion


24


A on tumbling lever


18


A to complete the engagement of the securing element


16


and the housing


14


.




Portions of this engagement will concurrently transpire as the connection section


26


of the securing element


16


penetrates the lock bolt opening


28


. This engagement is complete once each locking disc


30


passes through the associated detent portion


24


of the corresponding tumbling lever


18


. For example, locking disc


30


A will pass through detent portion


24


A of tumbling lever


18


A as locking disc


30


D passes through detent portion


24


D of tumbling lever


18


D. Concurrently, locking disc


30


B will pass through detent portion


24


B of tumbling lever


18


B while locking disc


30


C passes through detent portion


24


C of tumbling lever


18


C. In essence, all locking discs


30


will pass through the associated detent portions


24


, concurrently.




As seen in

FIG. 6

, in a preferred embodiment, the four spacing stems


31


, indicated as


31


A,


31


B,


31


C, and


31


D, create spacing intervals


33


between the locking discs


30


. For example, spacing stem


31


D creates spacing interval


33


between locking disc


30


C and


30


D. As seen in

FIG. 7

, in the locked position tumbling lever


18


D, specifically its detent portion


24


D, encompasses spacing stem


31


D located between locking disc


30


C and


30


D. Since the spacing stems


31


have a smaller circumference than the locking discs


30


, the detent portions


24


have a range of movement within the plane of movement


20


in which each tumbling lever


18


is located when the connection section


26


fully penetrates the housing


14


.




This range of movement of the tumbling levers


18


within the housing


14


creates an engagement between the locking disc


30


and the detent portions


24


when an incorrect combination of the locking device


10


is used in an attempt to remove the securing element


16


from the housing


14


.




For example, locking discs


30


are geometrically designed to pass through detent portions


24


on tumbling levers


18


only when the detent portions


24


are in the correct alignment as seen in

FIG. 10 and 13

. As previously mentioned, when locking device


10


is in its secured position, detent portions


24


encompass spacing stems


31


, which separate locking discs


30


. When the tactile engagement surfaces


22


of the tumbling levers


18


are manipulated, the alignment of the locking discs


30


and the detent portions


24


of the tumbling levers


18


are reconfigured. This realignment restricts the removal of the connection section


26


of the securing element


16


from the housing


14


. This restriction occurs due to the fact that once the tumbling levers


18


are adjusted away from their unlocked position, the detent portions


24


of the tumbling levers


18


shift within the plane of movement


20


to a position that restricts the movement of the locking discs


30


from passing through the detent portions


24


. As seen in

FIG. 8

,


9


,


11


, and


12


, this causes the locking disc


30


to engage detent portions


24


of the tumbling levers


18


when a user attempts to remove the securing element


16


without manipulating the tumbling levers


18


into the correct releasing combination.




When the securing element


16


penetrates the lock bolt opening


28


located in the housing


14


, an area of containment


32


is created between the securing element


16


and the housing


14


, as seen in

FIG. 2 and 3

. This area of containment


32


is used to secure the item


12


. Specifically, the securing element


16


includes a holding area


34


that is adapted to secure the item


12


between the securing element


16


and the housing


14


. Holding area


34


and housing


14


engage the item


12


once the item


12


is placed between the securing element


16


and the housing


14


and once the connection section


26


fully penetrates the housing


14


.




As seen in

FIG. 14 and 15

, a preferred embodiment of the design, of the securing element


16


and the housing


14


facilitate the securement of a firearm


12


, also called the item


12


. However, the external configuration of both the securing element


16


and the housing


14


can easily be adapted to secure other items


12


including, but not limited to, steering wheels, bicycles, and gymnasium lockers.




As seen in

FIG. 1

, the releasing mechanism


36


comprises a spring


38


, a button


40


and a contact portion


42


. In a preferred embodiment, the releasing mechanism


36


is attached to and penetrates the housing


14


in order to engage the securing element


16


once the securing element


16


penetrates the housing


14


. Specifically, the contact portion


42


of the releasing mechanism


36


engages the connection section


26


of the securing element


16


. Namely, locking disc


30


D is the portion of the connection section


26


that engages the releasing mechanism


36


. When the connection section


26


totally penetrates the housing


14


, the engagement between the locking disc


30


D and the contact portion


42


occurs in recessed area


44


. The releasing mechanism


36


is adapted to separate the securing element


16


from the housing


14


after the correct movement of each tumbling lever


18


allows the locking discs


30


to pass through the detent portions


24


of the tumbling levers


18


.




Once the correct manipulation of the tumbling levers


18


aligns the detent portions


24


of the tumbling levers


18


and the locking discs


30


, a user of the locking device


10


presses the button


40


of the releasing mechanism


36


. This action causes the contact portion


42


to force the securing element


16


out of the housing


14


, thereby releasing item


12


from the area of containment


32


. Please see FIG.


4


. The spring


38


then returns the button


40


to its original position. Both the spring


38


and the button


40


are located on the housing


14


opposite from the location of the lock bolt opening


28


in the housing


14


that receives the connection section


26


of the securing element


16


.




The plurality of tumbling levers


18


located inside the housing


14


can also be described as having a proximal end


46


and a distal end


48


. The proximal end


46


of each tumbling lever


18


contains the detent portion


24


which engages the connection section


26


of securing element


16


. The distal end


48


of each tumbling lever


18


contains the tactile engagement surface


22


so that tactile manipulation of the distal end


48


disengages the proximal end


46


. The disengagement is facilitated by the alignment of the detent portion


24


of the proximal end


46


of the tumbling lever


18


with the locking discs


30


of the connection section


26


of the securing element


16


. This alignment allows the releasement of the securing element


16


from the housing


14


, thus opening the locking device


10


.




Tactile manipulation of the distal ends


48


of the tumbling levers


18


aligns the proximal ends


46


of the tumbling levers


18


with the locking discs


30


of the securing element


16


. This alignment allows the releasing mechanisms


36


engaging the security element


16


to discharge the securing element


16


from the housing


14


.




The housing


14


includes plurality of pivot stems


50


used to control the movement of the tumbling levers


18


within the housing


14


. In a preferred embodiment, the locking device


10


has five pivot stems


50


attached to the housing


14


. The movement of each tumbling lever


18


is restricted by the pivot stems


50


in conjunction with a pivot opening


54


and directional control opening


52


located on each tumbling lever


18


. The pivot stems


50


, indicated as


50


A,


50


B,


50


C,


50


D, and


50


E in

FIG. 5

, are designed to assist in the control the movement of the tumbling levers


18


by restricting the movement of the tumbling levers


18


to either a planer slide or a planer rotation within the plane of movement


20


that each tumbling lever


18


is located.




The direction of movement of each tumbling lever


18


is restricted by providing each tumbling lever


18


with a pivot opening


54


to interact with a pivot stem


50


. The pivot opening


54


is an elongated opening that runs parallel to the longest length of each tumbling lever


18


. Each pivot opening


54


is designed to accept a pivot stem


50


and allow planer movement in directions parallel to the length of the tumbling lever


18


on which the pivot opening


54


is located. Each pivot opening


54


also allows rotation of the tumbling lever


18


with in the plane of movement


20


about pivot stem


50


. Please see

FIG. 8

,


9


,


10


,


11


,


12


and


13


.




For example, in a preferred embodiment of the invention the pivot opening


54


on each tumbling lever


18


accepts one of the pivot stems


50


while the directional control opening


52


on each tumbling lever


18


accepts a different pivot stem


50


. As seen in

FIG. 5

, pivot stem


50


E penetrates through directional control opening


52


D on tumbling lever


18


D while pivot stem


50


C penetrates through pivot opening


54


D on tumbling lever


18


D.




It is the design and interaction of the pivot stem


50


and the pivot opening


54


that restricts the movement of the tumbling lever


18


about the pivot stem


50


within the plane of movement


20


associated with each tumbling lever


18


. For example, when the tactile engagement surface


22


is manipulated in one of the longitudinal directions of the tumbling lever


18


, the tumbling lever


18


moves in that corresponding direction. This longitudinal movement is allowed since the pivot opening


54


traverses the tumbling lever


18


along the longitudinal length of tumbling lever


18


and pivot stem


50


is geometrical configured to correspond to the latitudinal width of pivot opening


54


on tumbling lever


18


. In a preferred embodiment, pivot opening


54


is approximately one half (½) inch in longitudinal length. It is this longitudinal length of the pivot opening


54


that allows tumbling lever


18


to slide in plane of movement


20


. Please see

FIG. 9

,


10


,


12


, and


13


.




However, when the tactile engagement surface


22


of a tumbling lever


18


is manipulated to move the tumbling lever


18


in a lateral direction within the plane of movement


20


, the pivot stem


50


and the pivot opening


54


restrict the movement of the tumbling lever


18


to a partial rotational movement about the pivot stem


50


within that plane of movement


20


. Partial rotational movement is accomplished through the interaction of pivot stem


50


and pivot opening


54


. Since pivot stem


50


geometrically conforms to the width of the pivot opening


54


, the edges of pivot opening


54


abut pivot stem


50


. This interaction restricts the lateral movement of tumbling lever


18


within the plane of movement


20


and only allows a rotational movement of tumbling lever


18


when the tactile engagement service


22


is moved laterally within the plane of movement


20


. Since tumbling lever


18


is not permanently fixed by any other point within the plane of movement


20


, tumbling lever


18


is allowed to rotate about pivot stem


50


.




This restriction on the direction of movement of the tumbling lever


18


by pivot stem


50


and pivot opening


54


limits the direction of movement of the detent portion


24


of each tumbling lever


18


. For example, if the tactile engagement


22


is moved in a longitudinal direction, the pivot stem


50


and the pivot opening


54


of the tumbling lever


18


restricts the tumbling lever


18


to movement in that same longitudinal direction. This in turn moves the detent


24


of the associated tumbling lever


18


in the same longitudinal direction. However, if the tactile engagement service


22


is moved in a lateral direction, the pivot stem


50


and pivot opening


54


restrict the tumbling lever


18


to a rotation about the pivot stem


50


. This rotation results in the tactile engagement surface


22


and the detent portion


24


moving in opposite latitudinal directions within the plane of movement


20


. This opposed movement is simply the result of the tumbling lever


18


rotating around the pivot stem


50


. Please see

FIG. 9

,


10


,


12


, and


13


.




The length of movement of each tumbling lever


18


is restricted by the interaction of a pivot stem


50


and the associate with each tactile engagement surface


22


. The pivot stem


50


protrudes from the housing


14


and passes through the directional control opening


52


on each tumbling lever


18


and enters a cavity opening


82


in each tactile engagement surface


22


. The directional control opening


52


allows the proximal end


46


of each tumbling lever


18


to move in either latitudinal or longitudinal directions within the plane of movement


20


. However, the directional control opening


52


restricts the movement of the distal end


48


of each tumbling lever


18


in each of these four distinct directions


56


through the interaction of one of the pivot stems


50


and the directional control opening


52


. As seen in

FIG. 5

, pivot stem


50


E penetrates through directional control opening


52


D on tumbling lever


18


D resulting in the distal end


48


of tumbling lever


18


D being restricted to movement in one of the four distinct directions


56


. The length of directional control opening


52


D in each of the four distinct directions


56


is the controlling factor in the length of movement of tumbling lever


18


in each of the longitudinal directions and the degree of rotation of tumbling lever


18


D about pivot stem


50


C. In a preferred embodiment of the invention, this movement is approximately one quarter ¼ of an inch in each of the four distinct directions


56


.




A key result of controlling the length of movement of the tactile engagement surfaces


22


of each tumbling lever


18


is the manipulation of the detent portion


24


of each tumbling lever


18


. The quantitative control of the length of the longitudinal movement of each tumbling lever


18


and the degree of rotation of each tumbling lever


18


within the plane of movement


20


in which each tumbling lever


18


is located corresponds to a detailed manipulation of the detent portion


24


of each associated tumbling lever


18


. The correct manipulation of the tactile engagement surface


22


allows the detent portion


24


on each tumbling lever


18


to geometrically align with the locking disc


30


on the connection section


26


of the securing element


16


. Once the locking disc


30


and the detent portions


24


are aligned, the releasing mechanism


36


can be activated, thereby allowing the securing element


16


to be ejected from the housing


14


. This action releases the item


12


held between the securing element


16


and the housing


14


.




In a preferred embodiment, the tactile engagement surfaces


22


on the tumbling levers


18


include a tactile button


74


. Each tactile button


74


engages one of the access openings


72


in the housing


14


, so that the tactile button penetrates the housing


14


. The tactile button


74


allows a human user of the locking device


10


to easily manipulate the tactile engagement surfaces


22


in order to align the detent portion


24


of each tumbling lever


18


with the connection section


26


of the securing element


16


.




Also in a preferred embodiment, the tumbling levers


18


include pivot stem openings


76


which allow the pivot stems


50


to pass through the tumbling lever


18


without engaging that particular tumbling lever


18


. The pivot stem openings


76


avoid unneeded interaction between the pivot stems


50


and the tumbling levers


18


. For example, as seen in

FIG. 5

, the tumbling lever


18


includes three pivot stem openings


76


which allow the pivot stems


50


A,


50


B, and


50


D to pass through the tumbling lever


18


without engaging the tumbling lever


18


.




In order to restrict the movement of the tumbling levers


18


to the individual planes of movement


20


for each respected tumbling lever


18


, spacing components


58


are used to retain each tumbling lever


18


in its own plane of movement


20


and separate each tumbling lever


18


from the other planes of movement


20


of the other tumbling levers


18


.




In a preferred embodiment, the locking device


10


is adapted to secure a firearm


12


, specifically a hand-gun. When the locking device secures a firearm


12


, the housing


14


is structurally adapted to conform to a portion of the stock


60


of a fireman


12


. In this embodiment of the locking device


10


, the securing element


16


includes a holding area


34


adjacent to the housing


14


, such that the holding area


34


engages the trigger


62


and trigger guard


64


of the firearm


12


when the locking device


10


is used to secure the firearm


12


.




When the locking device


10


is adapted to secure a firearm


12


, the locking device


10


includes stabilizers


66


,


68


, and


70


. Stabilizer


66


engages the barrel portion


78


of the firearm


12


and is attached to the securing element


16


. Stabilizer


68


is attached to the housing


14


near the location of the attachment between the housing


14


and the releasing mechanism


36


and engages the barrel portion


78


of the firearm


12


. Stabilizer


70


is attached to the housing


14


distal from the attachment between the housing


14


and the release mechanism


36


. Stabilizer


70


engages the stock


60


of the firearm


12


. Stabilizers


66


,


68


, and


70


are used to maintain a consistent engagement between the locking device


10


and the firearm


12


. The stabilizers


66


,


68


, and


70


make the locking device


10


more tamper resistant and increase the securing characteristics of the locking device


10


. In an alternate embodiment, the stabilizers


66


,


68


, and


70


can be arranged to engage the numerous geometrical shapes that the item


12


could embody.




Locking device


10


can easily be adapted to firearms other than hand-guns. Namely, the locking device


10


can maintain the spirit of the current invention and secure shot guns, rifles, and other forms of firearms. In alternate embodiments of the invention, securing element


16


and the housing


14


can easily be adapted by one skilled in the art to increase the size of the holding area


34


, and thus the area of containment


32


, to secure items


12


of varying sizes and shapes.




This invention also teaches a method for releasing an item


12


from a locking device


10


. The method comprises providing a tactile releasing lock


10


engaging in item


12


and manipulating without visual confirmation the tactile releasing lock


10


to free the item


12


.




In the method taught by this invention, the tactile releasing lock


10


includes a plurality of tactile engagement surfaces


22


so that manipulating, without visual confirmation, each tactile engagement surface


22


opens the tactile releasing lock


10


. The tactile releasing lock


10


also includes a releasing mechanism


36


which is manipulated, without visual confirmation, to separate the tactile releasing lock


10


from the item


12


.




In the method, the tactile releasing lock


10


includes a housing


14


, a securing element


16


, and a plurality of rods


18


located within the housing


14


. The securing element


16


engages the housing


14


such that the item


12


is held between the securing element


16


and housing


14


. Also, each rod


18


engages the securing element


16


within the housing


14


and is disengaged from the securing element


16


by manipulation, without visual confirmation, of the tactile engagement surface


22


located on each rod


18


. The method then teaches the disengagement of the securing element


16


from the housing


14


, thereby disengages the item


12


from both the securing element


16


and the housing


14


.




As tactile manipulation of the rod


18


A occurs, the tactile engagement surface


22


of the rod


18


A is restricted to four distinct directions of movement


56


by the engagement of pivot stem


50


B and directional control opening


52


A. The four distinct directions


56


are in either the longitudinal or latitudinal directions of rod


18


A and plane of movement


20


. As the tactile engagement surface


22


located on the distal end


48


of the rod


18


A moves in one of the four distinct directions


56


, pivot stem


50


A, protruding through pivot opening


54


A, and pivot stem


50


B, protruding through directional control opening


52


A restricts the movement of the detent portion


24


A of the rod


18


A. This restriction results in detailed movement of the detent portion


24


A of tumbling lever


18


A with respect to locking disc


30


A on connection section


26


. It is this detailed movement that operates the locking device


10


and allows locking disc


30


A on connection section


26


to pass by detent portion


24


A, thereby participating in the securing or releasing of securing element


16


from the housing


14


.




Pivot stem


50


B is also used to guide tumbling lever


18


B. Pivot stem


50


B enters pivot opening


54


B on rod


18


B and pivot stem


50


C enters directional control opening


52


B on rod


18


B. Once again as tactile manipulation of tumbling lever


18


B occurs in one of the four distinct directions of movement


56


for tumbling lever


18


B, pivot stems


50


B and


50


C, pivot opening


54


B and directional control opening


52


B control the movement of detent portion


24


B on rod


18


B by restricting rod


18


B to either longitudinal or rotational movement within plane of movement


20


for rod


18


B. Once again it is this detailed manipulation that controls the engagement between locking disc


30


B on connection section


26


and the detent portion


24


B on rod


18


B and allows locking disc


30


B to pass by detent portion


24


B, thereby participating in the securing or releasing of securing element


16


from the housing


14


.




This pattern continues for rods


18


C and


18


D with associated pivot stems


50


B,


50


C,


50


D, and


50


E, pivot openings


54


C and


54


D, and directional control openings


52


C and


52


D. For example, as the proximal end


46


of rod


18


C is located between locking disc


30


B and


30


C on connection section


26


, pivot stem


50


C penetrates pivot opening


54


C, while pivot stem


50


D penetrates directional control opening


52


C on rod


18


C. As manipulation of the tactile engagement surface


22


on rod


18


B occurs, rod


18


B traverses the plane of movement


20


in order to disengage the detent portion


24


B of rod


18


B from securing element


16


.




The method taught by this invention further includes a human user of the locking device


10


releasing the item


12


from the locking device


10


after the rods


18


are manipulated to allow the securing element


16


to disengage from the housing


14


. Once this manipulation has occurred, the human user presses the releasing mechanism


36


, which in turn forces the contact portion


42


of the releasing mechanism


36


to push connection section


26


of the securing element


16


out of the housing


14


. This allows the securing element


16


to disengage from the item


12


, thereby allowing the locking device


10


to fall from the item


12


. In a preferred embodiment, the human user uses the index finger to activate the releasing mechanism


36


to accomplish the aforementioned task. Once the human user has released the item


12


from the securing member


16


, the human user can remove his index finger from the releasing mechanism


36


and allow the housing


14


to fall from the item


12


.
