BACKGROUND OF THE INVENTION
Field of the Invention This invention relates generally to firearm locks, and more particularly to firearm 5 locks which are provided so as to be ,~ib~ lly integral with the firearm.
Desc,ivlion of the Relevant Art There is a continllin~ need to provide locks for firearms which will effectively prevent operation of the firearm by unauthorized users, but which are readily manipulated by authorized users to permit deactivation of the lock and operation of the firearm in an 10 emergency. It is desirable that such a lock be easily in~t~ll~ and non-intrusive to the in~egliLy of the firearm, such that continued reliability of the firearm is insured after in~t~ tion of the lock. It is also desirable that such a lock be entirely integral with the firearm, such that the lock or a key for the lock cannot be mi~pl~ed or lost.
There have been many atte~ ,L~ to devise locks for firearms which will prevent 15 lln~llthorized use of the firearm. These locks often are not integral with the firearm, and accordingly, must be removed in order to render the firearm operable, and can thereby be lost or misplaced. Prior locks for firearms which have been made to be integral with the firearm require extensive mo~ific~tion to the firearm, and thus can affect the reliability of the firearm and require time and eYpPn~e for proper inct~ tinn. These firearm locks are 20 som~tim~s difficult to manipulate, and the,c;fore can be dangerous in an elllel~ency where quick operation of the firearm is nece~ry.
There are many types of firearms, with different handle sizes and configur~tio~ and firing mP~h~ni~m designs. It would be desirable to provide a lock construction which is readily adaptable for use with many different types of guns.
CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 SUMMARY OF THE INVENTION
It is an object of the invention to prevent the operation of firearms by un~nthori~
users.
It is another object to the invention to provide a lock for firearms which is easily in~t~ll~d, It is yet another object of the invention to provide a lock for firearms which is integral with the firearm and will preclude the possibility that the lock will be lost or misplaced.
It is another object of the invention to provide a lock for firearms which will not 10 affect the reliability of the firearm.
It is still another object of the invention to provide a lock for firearms which can be readily deactivated to permit quick operation of the firearm in an emergency.
It is yet another object of the invention to provide a lock for firearms which can be in~t~ d in the firearm without extensive mo~1ifi~ ~tion to the firearm.
It is still another object of the invention to provide a lock assembly in which the combination required to open the lock can be readily changed by an authorized user.
It is another object of the invention to provide a lock assembly which can be adapted for different models and designs of hand guns or long arms.
These and other objects are accompli~hed by a gun lock assembly having an 20 engagement portion with a locked position in which a portion of the firing mlo~h~ni~m is operatively engaged to prevent firing of the firearm, and an unlocked position in which operation of the firearm is permitted. Several portions of the firing mPr,h~ni~m are currently ~lcrellcd, incl~lrling the h~m m~r, h~m m-or stirrup, leaf spring and rebound slide. The lock preferably comprises a lock housing with structure for ~tt~rhing the lock housing to the CA 02221482 1997-12-0~
W ~96/41997 PCTAUS96/10089 firearm.
An adaptor is ~lc;fc;ldbly provided which can be ~tt~hP~ to the frame of the firearm.
This can be accomplichPcl in pre-eYicting fir~u",s by removing the eYicting handle grip of the firearm and ~tt~hing an adaptor to the firearm with f~ctening structure. The adaptor is 5 preferably a plate with engagement structure for çng~ging a portion of the lock when the lock is in the locked position, and for rlicPng~ging the portion when the lock is in the nnloc~d position. This will prevent removal of the lock itself by un~nthorized users. The lock housing preferably çnclos~Ps at least part of the f~ctening structure and the en~gPmPnt structure, such that the adaptor and lock cannot be removed from the firearm when the lock 10 is in the locked position. The design of the adaptor can be readily adapted to fit most firearms, including hand guns and long arms. The adaptor can also be used to provide a manual safety for the firearm.
The adaptor can include moveable structure which is operable with movement of the lock to selectively enable operation of the firearm, or to prevent operation of the firearm.
15 In one embo-iimPnt a moveable lever connected to the adaptor plate can be moved by operation of the lock to selectively block movement of the rebound slide of a firearm. In another embo~imPnt, a lever ~tt~hP~ to the adaptor plate can be moved by operation of the lock to block the h~mmer stirrup of the firearm. In still another embo~lim~nt a lever :ltt~hP~ to the adaptor plate and operable by movement of the lock can be used to move the 20 draw bar of a firearm to selectively prevent operation of the firearm.
The lock is preferably a combination lock having a plurality of push buttons ~ceccible from the exterior of the housing for çntçrinf~ an ~lu~liate combination. A plurality of elongated ratchet mPm~çrs having ratchet teeth can be slidably disposed within the housing.
A ratchet return biasing member is provided to return the ratchet mPmbers to an initial CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 position. A ratchet pawl is connected to the push buttons and is operable to move the ratchet members against the biasing when the push buttons are depressed. ~d-lition~l biasing is provided to return the push buttons and ratchet pawl to the starting position. A detent is zlcSo~ rd with each ratchet member to prevent the return of the ratchet mPmber to the initial 5 position under the influ~nce of the ratchet return biasing.
A key-way carrier is ~ccoci~tP~ with each ratchet member and is moveable with each ratchet m~mber. A lock slide is positioned ~ cçnt to the ratchet mPmbPrs and in~ d~Ps a plurality of keys. The keys are slidable into the key-ways when the ratchet mPmbers and key-way carriers have been d~l~ssed an apl,-u~liale number of times by operation of the 10 push buttons to align each key-way with the ~~ e~ e key.
The engagement portion of the lock is operatively connected to the lock slide, such that the engagement portion can be moved to the unlocked position only when the key-ways are aligned with the keys of the lock slide according to the a~l~liate combination. The lock slide and the eng~gPrnPnt portion can then move to the unlocked position.
A reset is provided to initi~li7e the ratchet members for locking the lock and to provide a consistent starting point for re-entering the combination. Reset arms are disposed ent to the ratchet pawls and detents to move the pawls and detents out of engagement with the ratchet mp-mb~prs to release the ratchet members when the reset button is pushed.
This will permit the ratchet members to return to the initial position under the infl~ence of 20 the ratchet return spring.
The position of the key-way carriers with respect to the ~cco~ tp~ ratchet members is preferably adjustable so as to provide for ch~nging the combination of the lock. In a prere..ed embo~liment~ the key-way carrier can be inverted so as to present an alternate side of the key-way carrier to the keys of the lock slide. The alternate side has a key-way in a CA 02221482 1997-12-0~
W ~9614~997 PCT~US96/10089 dirrer~nt position, such that the number of oper~tio~c of the push button necçc~ry to align that key-way with the ~ e;Li~i~e key on the lock slide is changed.
St;ucture is provided for preventing the operation of the reset button when the lock slide is not fully in the locked position. Structure is also provided for urging the lock slide S and keys out of Png~gemlont with the key-way carriers to permit s~-bst~nti~lly free travel of the ratchet members to the initial position during the reset function.
The lock can be used with hand guns and long arms. The lock is particularly useful for e-ng~gement of any eYicting external safety m~h~nicm of the firearm. In the locked position, the engagement portion of the lock prevents movement of the safety to the "unsafe"
10 position, so as to prevent operation of the firearm. In the unlocked position, the engagement portion is moved out of operative engagement with the eYicting eYttom~l safety, so as to permit movement of the safety to the "unsafe" position and operation of the firearm.
An embodiment of the invention is useful for locking revolvers, which typically do not have an external safety m~h~ni.cm, A lever or other member is provided in ~csoci~tion 15 with the lock. The lever or other member has a locked position blocking the h~mm~r stirrup or another portion of the firing mech~nicm of the revolver to prevent operation of the revolver, and an unlocked position pe.lllittillg operation of the revolver. The lever or other member is moved to the blocking position by movement of the lock slide to the locked position, and can be moved from the blocking position with movement of the lock to the 20 unlocked position. The revolver lock of the invention is also useful with alternative lock constructions.

DETAILED DESCRIPTIQN OF THE PREFERRED EMBODIMENTS
An embodiment of the invention suitable for ~ltom~tic hand guns is shown in Figs.
1-7. The hand gun 20 inclu~es a handle frame 24, slide 28, h~mm~r 30, trigger 32, and safety 34, which can be according to known hand gun constructions. The safety 34 is S ~lepicted in the "safe" position in Fig. 1. Clockwise pivoting of a finger piece portion 36 of the safety 34 will place the safety in the "unsafe" position, which is n.~ce~ry to operate the firearm.
A lock 40 according to the invention is provided and includes an eng~glom~nt portion 46 which, in a locked position, blocks the safety 34 so as to prevent movement of the safety 34 to the "unsafe" position. In an unlocked position, the engagement portion 46 is pocitic)ned out of operative engagement with the safety 34 so as so permit the safety 34 to be moved to the "unsafe" position. The firearm can then be operated in the usual manner.
The lock 40 can be constructed according to several alternative lock constructions.
Combination locks are most pl~ef~ d because keys or other pieces are not neces~ry to unlock the lock. These other pieces can be lost, mi~pl~-ed, or left behind, which could render the firearm unoperable to the authorized user in an emergency sitll~tion. Push buttons 50a-c are provided, although fewer or more push buttons can alternatively be ~ltili7pA. The push buttons 50a-c could potentially be replaced by other combination lock structure, such as rotating dials or touch pads.
The precise size and configuration of the handle frame 24 can vary from firearm to firearm. It has been found to be useful to provide an adaptor 58 by which the lock 40 can be mounted to several different types of firearms without subst~nti~lly ch~nging the lock 40.
An adaptor 58 can be ~tt~h~d to the handle frame 24 by suitable structure, such as the screw 62 which passes through apel~ulc; 64 in the adaptor 58 to engage a female threaded socket CA 02221482 1997-12-0~
W O 96/41997 PCTflUS96~10089 68 in the handle frame 24. A threaded screw 70 can be positioned through an a~e.~u-G 71 to secure the adaptor 58 to the handle frame 24 at a femate threaded socket 73. The screw 70 can be provided with a female socket 72 at the head so as to receive a screw 76. The screw 76 is useful to secure a handle grip 78 to the handle frame 24. The handle grip 78 can S be configured to fit around a portion of the lock 40.
Structure is provided for eng~ging the lock 40 to the adaptor 58. A flange 80 can be provided which hingably engages coope.dling structure on the lock 40. A screw 82 can engage the lock 40 to a threaded socket 84 in the adaptor 58. Further, structure on the lock 40 is preferably provided which, when in the locked position, engages a clasp portion 88 on the adaptor 58 so as to prevent removal of the lock 40 from the adaptor 58 when the lock 40 is in the locked position. The screw 62 used to secure the adaptor 58 to the handle frame 24 is covered by the lock 40, and since the lock 40 cannot be removed from the adaptor 58 when in the locked position, the adaptor 58 also cannot be removed when the lock 40 is in the locked position.
A prefe.led lock construction is shown in Fig. 3. The lock 40 in~ des a lock housing 92. A push button finger piece 96 is ~c~o~ tpd with each of the push buttons SOa-c and extends through openings 100-102 that are provided in the housing 92. A pawl 106 is connected to each of the push buttons 50a-c. In a ple~llc~d emborlimPnt an e~ten~ion arm 112 connPct~ each pawl 106 to the push buttons 50a-c. The pawls 106 are p.~r~l~bly pivotally connectPcl to the extPn~ion arms 112 as by pivot pin 118. Each pawl 106 i ~ d~ s an eng~gPmPnt portion 120 which is adapted to engage an elong~tPll ratchet member 124.
The ratchet member 124 can have plurality of ratchet teeth 128 for engagement with the engagement portion 120 of the pawls 106 (Fig. 4). Biasing structure such as a ratchet return spring 132 is adapted to urge the ratchet mPmbers 124 toward the respective push buttons CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 50a-c. The ratchet return spring 132 can be secured by mounting pins 136 fixed to the housing 92 and to mounting pins 140 on the ratchet members 124.
Detents 144 are provided to retain each ratchet member 124 against the force of the ratchet return spring 132 following movement of the ratchet member 124 by the pawl 106.
The detents 144 can include engagement portions 148 which are adapted to engage the teeth 128 of the ratchet members 124. The detents 144 can be pivotally mounted to the housing 92 by suitable structure such as pivot pins 152.
The pawls 106 and detents 144 preferably are biased into engagement with the ratchet members 124 so as to prevent slippage. One or more biasing springs, such as the biasing spring 156, can be provided to pe~ ll this function. The biasing spring 156 can have spring arms 158, lS9 which contact the pawls 106 and detents 144. The biasing spring 156 can be mounted in suitable fashion, such as to the mounting posts 160.
The pawls 106 and ratchet teeth 128 are configured according to known ratchet constructions so as to provide for engagement during a downward stroke of the push buttons lS 50a-c, and slippage of the pawl 106 past the ratchet teeth 128 during the return stroke of the push buttons 50a-c. Return of the push buttons 50a-c is accomplished by push button return springs 164 associated with each of the push buttons 50a-c, which are adapted to bias the push buttons 50a-c away from the ratchet members 124. The detents 144 are constructed in known fashion so as to engage the ratchet members 124 oppositely to the pawls 106, such that the ratchet teeth 128 can move past the detents 144 when the ratchet members are moved by the pawls 106.
Structure may be provided to guide the sliding movement of the ratchet members 124 and the pawls 106. In one embo~limçn~ rails 168 are provided with the housing 92 and are adapted to slidably engage a groove 170 formed in a back surface of each ratchet m ~m bçr WO 96)41997 PCT/US96/10089 124. Grooves 172 can be formed in the housing 92 for guiding the movement of the ratchet members. Pawl guides 176 can also be provided with the housing 92 to guide the motion of the pawls 106. Ratchet stops 180 can be provided to limit the movement of the ratchet mPmbçrs 124 in responce to the biasing of the ratchet return springs 132.
Key-way carriers l90a-c are ~c$o~ ted with each of the ratchet mPmhers 124 and adapted to move with movement of the ratchet mem~prs 124. In a ~ felled embo-lim~ont the key-way carriers 190 are directly engaged to the ratchet members 124, such as by tongue 192 and groove 193 construction. Each key-way carrier 190a-c includes a ~ e.;li~/e key-way 194a-c, which can be formed as a notch or groove therein.
A lock slide 200 is operatively conn~cted to the engagement portion 46 and can extend through a suitable opening 204 in the housing 92. The lock slide 200 inrlndes keys 206a-c which, when assembled, are positioned subst~nti~lly ~ acçnt to respective key-way carriers l90a-c. The lock slide 200 and keys 206a-c are ju~c~osed to the key-way carriers l90a-c such that transverse movement of the lock slide 200 relative to the key-way carriers lS l90a-c is bloclced by contact between the keys 206a-c and the key-way carriers l90a-c.
The key-ways 194a-c are ~limpncioned to accept the keys 206a-c. ~lignm~nt of thekey-ways 194a-c with the keys 206a-c is accomplished by de~ressillg the ~e,pecli~e push buttons 50a-c the a~ ulJliate number of times Cull~ onding to the position of the key-ways 194a-c on the respective key-way carriers l90a-c. A key-way 194 that is pocitioned nearer to the end of the ratchet m~mber 124 that is closest to the le~ec~ e push button S0 will require more op~r~tionc of the push button 50 in order to move the ratchet m~mber 124 and ~coc;~ted key-way carrier 190 a snffifi~nt ~lict~nre to align the key-way 194 with the respective key 206. Different positions of the key-way 194 on the key-way carrier 190 will require more or fewer operations of the push button S0. Accordingly, the relative CA 02221482 1997-12-0~
poci~io2ling of the key-ways 194a-c on the resl.e~ ,re key-way carriers l90a-c collespollds to a combination n-o~eSc~ry to align all of the key-ways 194a-c with the keys 206a-c, so as to permit transverse movement of the keys 206a-c into the key-ways 194a-c, and co"~ponding movement of the lock slide 200. The engagement portion 46 will move with S the lock slide 200 to the "llnloçk~1" position.
A lock slide biasing spring 210 can be provided to urge the lock slide 200 to the unlocked position in which the keys 206a-c are urged into the key-ways 194a-c. The biasing spring 210 can be mounted to the lock slide 200 at a mounting post 214, and can be engaged to a portion of the housing at a post 218 (Fig. 4).
Reset structure is provided for retuming the ratchet members 124 to an initial position, which will move the key-ways 194 out of ~lignm~nt with the keys 206 to lock the lock 40, and so that the combination can be entered from a concictçnt starting point. The reset structure can engage the pawls 106 and detents 144 to move them out of engagement with the ratchet members 124. The ratchet return springs 132 will move the ratchet membçrs 124 to an initial position defined by the ratchet stops 180. A reset slide 220 can be provided with a plurality of reset arms 222. The reset slide 220 is so constructed that, when assembled, the reset arrns 222 are ju~posed to the pawls 106 and detents 144, which extend somewhat out of the plane of the ratchet m~mh~rs 124. The reset slide 220 is slidably disposed within the lock, and can be supported by a portion 226 which is slidably eng~ged 20 in a slot 230 formed in the housing 92. A slot 234 can be provided to receive a mounting screw 238, which engages a threaded socket 240 in the housing 92 so as to provide slidable engagement of the reset slide 220 to the housing 92. A reset button 248 of the reset slide 220 can extend out of an opening 250 in the housing 92 for manipulation by the O~ld~Ol.
Sliding movement of the reset slide 220 will cause contact between the reset arms 222 and CA 02221482 1997-12-0~
W O 96141997 PCT~US96/10089 the pawls 106 and detents 144 to move the pawls 106 and detents 144 out of çng~gemPnt with the ratchet teeth 128 of the ratchet members 124.
In operation, when the lock slide 200 is in the locked position, the engagement portion 46 will be positioned so as to prevent movement of the safety 34 from the "unsafe"
5 position. Keys 206a-c abut the ,e~e~ e key-way carriers l90a-c such that movement of the lock slide 200 to the unlocked position is not possible. Upon operation of the re~.~e~ e push buttons 50a-c, the key-ways 194a-c are aligned with the keys 206a-c. The lock slide 200 is urged by the lock slide spring 210 such that the keys 206a-c are moved into the ~ uecLi~/e key-ways 194a-c. The lock slide 200 and engagement portion 46 thereby are 10 pel-l~iLIed to move from the locked position to the unlocked position, p~ ing movement of the safety 34 to the "unsafe" position, and operation of the firearm. T ocking of the firearm can be accompli~hP~ by m~ml~lly moving the eng~PmPnt portion 46 and lock slide 220 to the locked position in which the keys 206a-c are out of Png,.gPmPnt with the key-ways 194a-c. The lock slide 220 must be held against the biasing of the lock slide spring 210, so 15that ~rid~p-nt~l locking is avoided. Movement of the reset button 248 and reset slide 220 will cause the reset arms 222 to move the ratchet pawls 106 and the detents 144. This will permit movement of the ratchet mpmbers 124 and ~soci~ted key-way carriers l90a-c to the initial position in which movement of the keys 206a-c is blocked by the key-way carriers l90a-c. This will lock the lock 40 and will also position each of the ratchet members 124 20 at the initial position defined by the ratchet stops 180 for subsequent entP-ing of the combination.
~ Movement of the pawls 106 and detents 144 out of Pn~Pmpnt with the ratchet members 124 prior to the completion of the movement of the keys 206a-c out of the e~e;Live key-ways 194a-c can result in dr~.gp:ing of one or more of the keys 206a-c against CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 sides of the l- s~e~Li~e key-way carriers 190a-c. This will impede the return of the key-way carrier 190 and res~ /e ratchet mP~nb.or 124 to the initial position during the reset function. The subsequent release of the reset button 248 will cause the ratchet pawls 106 and detents 144 to engage the respective ratchet member 124, which may not have returned fully S to the initial position because of the dragging against the keys 206. Entering of the a~r~liate combination will be confused because the ratchet m~mbçr 124 and key-way carrier 140 will not be in the true starting position. It is therefore desirable to provide structure to ensure that the reset button 248 is not operable until the lock slide 200 and keys 206a-c are completely out of engagement with key-way carriers l90a-c.
A pivoting reset stop lever 256 can be provided and can be pivotally secured to the housing 92 as by a mounting pin 260. A spring 262 biases the reset stop lever 256 into engagement with a shoulder 266 on the reset slide 220. Completion of the movement of the lock slide 200 to the locked position causes contact between the lock slide 200 and the reset stop lever 256 so as so pivot the lever out of engagement with the reset slide 220.

W ~ 9614~997 PCTGUS96/10089 The key-way carriers 190 can include alternate key-ways 290 subst~nti~lly on a side of the key-way carrier 190 o~o~ite the key-way 194. The f~tenin~ structure such as the tongue 192 and groove 193 is such that the key-way carrier 190 can be inverted to face the ~ltern~tP key-way 290 to the lock slide 200 and keys 206. The alternate key-way 290 can 5 be at a different position along the key-way carrier 190 such that inversion of the key-way carrier 190 will result in ~1tP~tioll of the combination nP~ç~ y to align the alternate key-way 290 with the respective key 206 to open the lock. The combination can thereby be readily changed if it becomes known to un~-lthorized users.
It is preferable that structure be provided to prevent the removal of the lock itself by 10 unauthorized users and, as stated earlier, a catch 88 on the adaptor 58 can be aligned with a cooperating catch 302 on the lock housing 92. A portion 298 of the lock slide 200 moves behind the catch 88 and in front of the catch 302 when the lock slide 200 is in the locked position. The adaptor 58, lock slide 200, and housing 92 will thereby be interconnected to secure the lock 40 to the adaptor 58 when the lock 40 is in the locked position. Further, the 1~ lock housing 92 covers and prevents access to the mounting screw 62, which secures the adaptor 58 to the frame 24. The intelcollllP,cting structure provides a construction whereby the lock 40 cannot be removed from the hand gun when the lock 40 is in the locked position.
The principles ~ closP~I herein can be applied to locks having dirre.c;-lt co~ onent configurations. For example, it is possible to construct a lock by which the keys are 20 provided with the ratchet member and the key-ways are provided on the lock slide. Also, the keys and key-ways can be altered to various forms of protrusions and depressions, the ~lignment of which will permit movement of one relative to the other. Other variations as would be a~al~nt to one skilled in the art would also be possible.
An alternative embo~limPnt of the invention is useful for revolvers. Revolvers do not CA 02221482 1997-12-0~
include an external safety mPrh~ni~m, and accordingly, another portion of the firing me~h~ni~m must be operatively engaged in the locked position to prevent operation of the firearm. Figs. 8-11 depict such an embo-liment of the invention for a revolver 306. In this embo~imPnt, a lock 310 is provided with an engagement portion 314. The lock 310 can be similar in construction to the lock 40 described above, or can be made according to a dirrt;lel~l construction, inc~ ling locks that are not combination locks.
Operation of the firearm 306 requires rearward pivoting of a h~mmer 308 upon squeezing of a trigger 312. A h~mmer stirrup 316 is engaged to the h~mmer 308 according to known firearm constructions. A h~mmer return spring 318 is provided to propel the h~mmPr stirrup 316 and h~mmPr 308 during firing of the weapon. An end 319 of theh~mmPr stirrup 316 in some firearm constructions extends into an opening 326 of the frame 330 of the firearm.
An adaptor 320 can be provided and secured to the firearm 306 by suitable f~tPning structure. In one embo-iimPnt a screw 344 is passed through an aperture 348 in the adaptor 340 and engaged to a suitable socket 352 in an opposing handle grip 356. The adaptor 320 will then be secured to the frarne 330 of the firearm 306.
A lever 366 is provided and can be pivotally mounted to the adaptor 340 through a mounting ape.~u~ 370 which is secured to a mounting pin 374 on the adaptor 320. A
second, blocking lever 380 is pivotally mounted to the adaptor 320, as by a mounting apel~u-e 384 which is positi~np~ on a mounting post 390 of the adaptor 320. The first lever 366 can be eng~gP~ to the bloc~ing lever 380 by a suitable engagement post 381 on the first lever 366, which cooperates with an engagement groove 383 on the blocking lever 380.
In a first, unlock~d position, the blocking lever 380 is po~itiorle~ out of ~lignmPnt with the end 319 of the h~mmPr stirrup 316 (Fig. 10). Normal operation of the firearm is CA 02221482 1997-12-0~ :
W O96141997 PCTrUS96/10089 thereby permitted. In a locked position, however, the çng~gPmPnt portion 314 en~ s and pivots the first lever 366 clockwise and secures it in this pivoted position. Pivoting of the first lever 366 causes counter-clockwise pivoting of the blocking lever 380. A blocking portion 388 of the blocking lever 380 is moved over the end portion 319 of the h~mmPr S stirrup 316 to prevent movement of the h~m mer stirrup 316 and operation of the weapon.
Structure can be provided to fix the position of the blocking lever 380. A suitable spring 400, such as a leaf spring, can be secured through a mounting ap~"u~ 404 by a screw 408, which engages a suitable socket 412 in the adaptor 320. A groove 416 in the adaptor 320 is adapted to receive a portion of the leaf spring 400 and provides ~ lition~l f~tPning structure. The spring 400 includes either of a tit or a dimple to cooperate with two colle~onding tits or dimples on a surface 426 of the blocking lever 380. A dimple 428 can engage either of tits 434, 436 to secure the blocking lever in either the locked or Imloc position.
The lock 310 can be secured to the adaptor 320 by suitable structure such as a screw 444 which engages a suitable threaded opening 446 on the adaptor 320. A flange 450 can be provided to engage a co~ onding portion of the lock 310. Further, a catch 454 can be provided to engage a portion of the lock, such as a portion of the lock slide as previously ~liccuc~e~, to prevent removal of the lock 310 from the adaptor 320 when the lock is in the locked position. The lock also covers the mounting screw 344 such that an intercQllllP~ting structure is provided wherein the lock 310 cannot be removed from the firearm 306 when the lock 310 is the locked position. A handle grip 460 can be f~hionP~ to fit over the lock 310 and secure to the adaptor 320 as by a screw 436 çng~ging an ape~lule 438.
The safety mPçh~ni~m of the invention can be used, with minor mo iifiç~fion, in gun designs of many descriptions. The operation of most hand guns and long arms is well CA 02221482 1997-12-0~

Suitable lock structures are also ~licclosed in Applicant's U.S.
Patent Nos. 4,987,693 and 5,090,148, and Applicant's co-pending applic~til)nc. The ~licclosnres of these patents and applications are hereby incorporated fully by reference.
The type of lock that is used can be selected from a number of suitable lock decignc Desirable r~Lules include tarnper recict~nce and a reduced size which will not intelrel~ with normal operation of the firearm. It is also desirable that the lock be operable without the ~ccict~nl~e of external accessories such as keys, which can be lost or misplaced and are difficult to manipulate in an emergency. It further is desirable that dials and other similar CA 02221482 1997-12-0~
W O 9614~997 . PCTAUS96/10089 lock-opening constructions be avoided, as these cannot be utilized in dark en~,i,v....~- .nc and are also difficult to manipulate in an emergency. In a ~lcrcl~cd emb~iimPnt, the lock inrll1des push buttons which operate to unlock the lock when the buttons have been pressed a proper number of times or in a proper sequential order.
There is shown in Figs. 12-13 an adaptation of the invention for long arms. The princiI)lPs of the invention as applied to hand guns are equally applicable to long arms, namely, that a combination lock can be applied to a long arm. The lock has a portion capable of operatively eng~ging a portion of the firing merh~nicm of the long arm so as to prevent operation of the long arm. The lock has an unlocked position in which operation of the long arm is ~ llitled. The lock can be adapted to cooperate with an eyicting exterior safety of the long arm, or alternatively, can be adapted to operatively engage an internal portion of the firing mP~h~nicm.
The long arm 500 inclndPs a stock 510, barrel 520, and trigger 524. The stock 510, according to some long arm constructionc, has an opening that is ~pt~P~ to engage the receiver portion 530 of the frame of the long arm. The receiver portion 530 can include top tang 532 and bottom tang 534. Suitable f~ctPning structure such as a receiver bolt 538 passes through an aperture 540 in the receiver portion 530 and engages a co,lespollding portion of the stock 510 to secure the stock 510 to the receiver portion 530. A barrel release 544 is somPtimes provided to permit "breaking" of the long arm for loading and unlo~ling pu,~oses. An exterior safety 550 is commonly provided and is moveable between "safe" and "unsafe" positions which will respectively prevent or permit operation of the firearm. The movement of the safety ne~ecc~ry to operate the long arm varies according to them~mlf~rtllrer, but in the presently llicrlosed embo~liment, sliding movement of the safety 550 forward results in the "unsafe" position nP~ecc~ry for operation of the firearm.
CA 02221482 1997-12-0~
A lock 552 can be secured to the stock 510 or to another portion of the firearm that is external to the receiver portion 530. The lock 552 is secured to the firearm by suitable structure, which can include screws. The lock 552 has an engagement portion 554 that is moveable between locked and unlocked positions. In the locked position, the engagement portion 554 operatively eng~ges the external safety 550 to prevent movement of the safety to the unlocked position. In the firearm shown in the drawing, the engagement portion 554 in the locked position prevents forward movement of the external safety 550. In the unlockPd position, the engagement portion 554 moves to a position permitting forward movement of the external safety 550 to the unlocked, "unsafe" position. Combination entering structure such as buttons 558, and a reset button 560, can be provided with the lock 552 as previously described and as described in Applicant's other application~ and patents.
The lock 552 is preferably mounted to the long arm 500 by a adaptor 564. Suitable structure such as a stock bolt 568 can pass through an a~el~u-e 570. An apellure 574 can be provided in the stock 510 to permit passage of the stock bolt 568, which will pass be~w~n the top tang 532 and the bottom tang 534 of the receiver portion 530 and engage a suitable threaded opening in an opposing portion of the stock 510. In a prerelr~;d embo-limPnt the lock is positioned such that the stock bolt 568 subst~nti~lly aligns with the receiver bolt 538 when each is in~t~ll~1. The receiver bolt 538 becomes operatively engaged to the stock bolt 568 so as to prevent the removal of the receiver bolt 538 unless the bolt 568 is first removed.
In one emborlimpnt~ the receiver bolt 538 includes a groove 574 through which the stock bolt 568 passes when the stock bolt 568 is engaged to the stock 510. Other interlot~king constructions are possible, such as slots, catches and the like.
The lock 552 can be secured to the adaptor 564 by a latch 580 as previously described. A catch 582 filnf tinll~ as previously ~lescrihed to lock the lock 552 to the adaptor CA 02221482 1997-12-0~

A well 586 can be provided in the stock 510 to receive the adaptor 564 and the lock 552. A decorative cover 590 can be secured by screws 592. The screws 592 can engage suitable a~-Lules 594 in the stock 510. It is alternatively possible that the lock 552 will be configured to engage an internal portion of the firing mP~h~ni~m In this inet~n~e, a suitable opening would be provided in this stock 510 to permit access to the interior of the long arm 500.
The locks described in the above embo-limente of the invention require the user to enter the combination selection in the form of a predetermined number of discrete depressions of each button. Other combination selections are contemplated. For er~mrle, the combination could require the user to depress a plurality of buttons in a proper sequential order. Other types of lock mp~h~niems are also known in the art, and are within the scope of the present invention. The lock described can also have utility as a lock for items other than firearms, such as Sllitc~ePs, briefcases, and jewelry boxes.
The invention provides an adaptor that includes structure for connectin~ the adaptor to the firearm, preferably the frame of the firearm. These include the adaptors 58, 320 and 564 ~iieclosed herein, as well as morlifi~tione within the scope of the invention. The adaptor can include structure for en~ing at least a portion of the firing mPrh~ni~m of the firearm so as to prevent operation of the firearm. The adaptor 320 shown in Figs. 9-11 inclu~Ps pivotable levers 366, 380 which will accomplish this purpose. The levers, in some embodimPnt~, can be manipulated manually to provide a manual safety for handguns which do not have an existing manual safety. The adaptor will most often be utilized with a lock CA 02221482 1997-12-0~

in the manner tli~closec~ herein so as to provide a means for selectively ~r",iUi.,g or preventing operation of the firearm. The adaptor preferably has structure for col1nP~I;ng the adaptor to the lock when the lock is in the locked position so as to prevent unauthorized removal of the lock from the adaptor. This is shown by the clasp 88 of the adaptor 58, and 5 the clasp 454 shown in Fig. 9. A portion of the lock, or structure operatively connPcte~ to the lock, ~Icrcl~bly covers structure which is utilized to secure the adaptor to the firearrn.
In this manner, an interlocking structure is provided by which the lock, when in the locked position, cannot be removed from the adaptor, and the adaptor cannot be removed from the firearm.
It is possible to use an adaptor accordin~ to the invention with handguns of many different designs, inçl~lfling both revolvers and automatics, as well as long arms. The adaptor can be utilized with a variety of a variety of different lock decignc~ incl~ ing those described in the present application and applicant's other applications and patents, as well as other unrelated lock constructions. The adaptor can also be combined with a grip to provide 15 ready inct~ tion into the firearm.
An alternative embodiment of an adaptor plate that is used for blocking the rebound slide of a handgun is shown in Fig. 14. The rebound slide 600, as is known in the art, operates to draw the h~mmer 604 of the firearm backward upon squeezing of the trigger 608.
Also, a slot is provided in the rebound slide 600 through which a co" i~onding protrusion 20 (not shown) of the h~mmer 604 moves during the cocking oper~tion. The movement of this protrusion in the slot of the rebound slide 600 guides the forward motion of the h~mmPr during the firing operation. An adaptor plate 610 according to the invention is provided with structure for blocking movement of the rebound slide. The adaptor 610 has ~so~i~ted therewith a blocking member 612 which is moveable from a first position, blocking the CA 02221482 1997-12-0~

BACKGROUND OF THE INVENTION
Field of the Invention This invention relates generally to firearm locks, and more particularly to firearm 5 locks which are provided so as to be ,~ib~ lly integral with the firearm.
Desc,ivlion of the Relevant Art There is a continllin~ need to provide locks for firearms which will effectively prevent operation of the firearm by unauthorized users, but which are readily manipulated by authorized users to permit deactivation of the lock and operation of the firearm in an 10 emergency. It is desirable that such a lock be easily in~t~ll~ and non-intrusive to the in~egliLy of the firearm, such that continued reliability of the firearm is insured after in~t~ tion of the lock. It is also desirable that such a lock be entirely integral with the firearm, such that the lock or a key for the lock cannot be mi~pl~ed or lost.
There have been many atte~ ,L~ to devise locks for firearms which will prevent 15 lln~llthorized use of the firearm. These locks often are not integral with the firearm, and accordingly, must be removed in order to render the firearm operable, and can thereby be lost or misplaced. Prior locks for firearms which have been made to be integral with the firearm require extensive mo~ific~tion to the firearm, and thus can affect the reliability of the firearm and require time and eYpPn~e for proper inct~ tinn. These firearm locks are 20 som~tim~s difficult to manipulate, and the,c;fore can be dangerous in an elllel~ency where quick operation of the firearm is nece~ry.
There are many types of firearms, with different handle sizes and configur~tio~ and firing mP~h~ni~m designs. It would be desirable to provide a lock construction which is readily adaptable for use with many different types of guns.

It is another object of the invention to provide a lock assembly which can be adapted for different models and designs of hand guns or long arms.
These and other objects are accompli~hed by a gun lock assembly having an 20 engagement portion with a locked position in which a portion of the firing mlo~h~ni~m is operatively engaged to prevent firing of the firearm, and an unlocked position in which operation of the firearm is permitted. Several portions of the firing mPr,h~ni~m are currently ~lcrellcd, incl~lrling the h~m m~r, h~m m-or stirrup, leaf spring and rebound slide. The lock preferably comprises a lock housing with structure for ~tt~rhing the lock housing to the CA 02221482 1997-12-0~
W ~96/41997 PCTAUS96/10089 firearm.
An adaptor is ~lc;fc;ldbly provided which can be ~tt~hP~ to the frame of the firearm.
This can be accomplichPcl in pre-eYicting fir~u",s by removing the eYicting handle grip of the firearm and ~tt~hing an adaptor to the firearm with f~ctening structure. The adaptor is 5 preferably a plate with engagement structure for çng~ging a portion of the lock when the lock is in the locked position, and for rlicPng~ging the portion when the lock is in the nnloc~d position. This will prevent removal of the lock itself by un~nthorized users. The lock housing preferably çnclos~Ps at least part of the f~ctening structure and the en~gPmPnt structure, such that the adaptor and lock cannot be removed from the firearm when the lock 10 is in the locked position. The design of the adaptor can be readily adapted to fit most firearms, including hand guns and long arms. The adaptor can also be used to provide a manual safety for the firearm.
The adaptor can include moveable structure which is operable with movement of the lock to selectively enable operation of the firearm, or to prevent operation of the firearm.
15 In one embo-iimPnt a moveable lever connected to the adaptor plate can be moved by operation of the lock to selectively block movement of the rebound slide of a firearm. In another embo~imPnt, a lever ~tt~hP~ to the adaptor plate can be moved by operation of the lock to block the h~mmer stirrup of the firearm. In still another embo~lim~nt a lever :ltt~hP~ to the adaptor plate and operable by movement of the lock can be used to move the 20 draw bar of a firearm to selectively prevent operation of the firearm.
The lock is preferably a combination lock having a plurality of push buttons ~ceccible from the exterior of the housing for çntçrinf~ an ~lu~liate combination. A plurality of elongated ratchet mPm~çrs having ratchet teeth can be slidably disposed within the housing.
A ratchet return biasing member is provided to return the ratchet mPmbers to an initial CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 position. A ratchet pawl is connected to the push buttons and is operable to move the ratchet members against the biasing when the push buttons are depressed. ~d-lition~l biasing is provided to return the push buttons and ratchet pawl to the starting position. A detent is zlcSo~ rd with each ratchet member to prevent the return of the ratchet mPmber to the initial 5 position under the influ~nce of the ratchet return biasing.
A key-way carrier is ~ccoci~tP~ with each ratchet member and is moveable with each ratchet m~mber. A lock slide is positioned ~ cçnt to the ratchet mPmbPrs and in~ d~Ps a plurality of keys. The keys are slidable into the key-ways when the ratchet mPmbers and key-way carriers have been d~l~ssed an apl,-u~liale number of times by operation of the 10 push buttons to align each key-way with the ~~ e~ e key.
The engagement portion of the lock is operatively connected to the lock slide, such that the engagement portion can be moved to the unlocked position only when the key-ways are aligned with the keys of the lock slide according to the a~l~liate combination. The lock slide and the eng~gPrnPnt portion can then move to the unlocked position.
A reset is provided to initi~li7e the ratchet members for locking the lock and to provide a consistent starting point for re-entering the combination. Reset arms are disposed ent to the ratchet pawls and detents to move the pawls and detents out of engagement with the ratchet mp-mb~prs to release the ratchet members when the reset button is pushed.
This will permit the ratchet members to return to the initial position under the infl~ence of 20 the ratchet return spring.
The position of the key-way carriers with respect to the ~cco~ tp~ ratchet members is preferably adjustable so as to provide for ch~nging the combination of the lock. In a prere..ed embo~liment~ the key-way carrier can be inverted so as to present an alternate side of the key-way carrier to the keys of the lock slide. The alternate side has a key-way in a CA 02221482 1997-12-0~
W ~9614~997 PCT~US96/10089 dirrer~nt position, such that the number of oper~tio~c of the push button necçc~ry to align that key-way with the ~ e;Li~i~e key on the lock slide is changed.
St;ucture is provided for preventing the operation of the reset button when the lock slide is not fully in the locked position. Structure is also provided for urging the lock slide S and keys out of Png~gemlont with the key-way carriers to permit s~-bst~nti~lly free travel of the ratchet members to the initial position during the reset function.
The lock can be used with hand guns and long arms. The lock is particularly useful for e-ng~gement of any eYicting external safety m~h~nicm of the firearm. In the locked position, the engagement portion of the lock prevents movement of the safety to the "unsafe"
10 position, so as to prevent operation of the firearm. In the unlocked position, the engagement portion is moved out of operative engagement with the eYicting eYttom~l safety, so as to permit movement of the safety to the "unsafe" position and operation of the firearm.
An embodiment of the invention is useful for locking revolvers, which typically do not have an external safety m~h~ni.cm, A lever or other member is provided in ~csoci~tion 15 with the lock. The lever or other member has a locked position blocking the h~mm~r stirrup or another portion of the firing mech~nicm of the revolver to prevent operation of the revolver, and an unlocked position pe.lllittillg operation of the revolver. The lever or other member is moved to the blocking position by movement of the lock slide to the locked position, and can be moved from the blocking position with movement of the lock to the 20 unlocked position. The revolver lock of the invention is also useful with alternative lock constructions.

DETAILED DESCRIPTIQN OF THE PREFERRED EMBODIMENTS
An embodiment of the invention suitable for ~ltom~tic hand guns is shown in Figs.
1-7. The hand gun 20 inclu~es a handle frame 24, slide 28, h~mm~r 30, trigger 32, and safety 34, which can be according to known hand gun constructions. The safety 34 is S ~lepicted in the "safe" position in Fig. 1. Clockwise pivoting of a finger piece portion 36 of the safety 34 will place the safety in the "unsafe" position, which is n.~ce~ry to operate the firearm.
A lock 40 according to the invention is provided and includes an eng~glom~nt portion 46 which, in a locked position, blocks the safety 34 so as to prevent movement of the safety 34 to the "unsafe" position. In an unlocked position, the engagement portion 46 is pocitic)ned out of operative engagement with the safety 34 so as so permit the safety 34 to be moved to the "unsafe" position. The firearm can then be operated in the usual manner.
The lock 40 can be constructed according to several alternative lock constructions.
Combination locks are most pl~ef~ d because keys or other pieces are not neces~ry to unlock the lock. These other pieces can be lost, mi~pl~-ed, or left behind, which could render the firearm unoperable to the authorized user in an emergency sitll~tion. Push buttons 50a-c are provided, although fewer or more push buttons can alternatively be ~ltili7pA. The push buttons 50a-c could potentially be replaced by other combination lock structure, such as rotating dials or touch pads.
The precise size and configuration of the handle frame 24 can vary from firearm to firearm. It has been found to be useful to provide an adaptor 58 by which the lock 40 can be mounted to several different types of firearms without subst~nti~lly ch~nging the lock 40.
An adaptor 58 can be ~tt~h~d to the handle frame 24 by suitable structure, such as the screw 62 which passes through apel~ulc; 64 in the adaptor 58 to engage a female threaded socket CA 02221482 1997-12-0~
W O 96/41997 PCTflUS96~10089 68 in the handle frame 24. A threaded screw 70 can be positioned through an a~e.~u-G 71 to secure the adaptor 58 to the handle frame 24 at a femate threaded socket 73. The screw 70 can be provided with a female socket 72 at the head so as to receive a screw 76. The screw 76 is useful to secure a handle grip 78 to the handle frame 24. The handle grip 78 can S be configured to fit around a portion of the lock 40.
Structure is provided for eng~ging the lock 40 to the adaptor 58. A flange 80 can be provided which hingably engages coope.dling structure on the lock 40. A screw 82 can engage the lock 40 to a threaded socket 84 in the adaptor 58. Further, structure on the lock 40 is preferably provided which, when in the locked position, engages a clasp portion 88 on the adaptor 58 so as to prevent removal of the lock 40 from the adaptor 58 when the lock 40 is in the locked position. The screw 62 used to secure the adaptor 58 to the handle frame 24 is covered by the lock 40, and since the lock 40 cannot be removed from the adaptor 58 when in the locked position, the adaptor 58 also cannot be removed when the lock 40 is in the locked position.
A prefe.led lock construction is shown in Fig. 3. The lock 40 in~ des a lock housing 92. A push button finger piece 96 is ~c~o~ tpd with each of the push buttons SOa-c and extends through openings 100-102 that are provided in the housing 92. A pawl 106 is connected to each of the push buttons 50a-c. In a ple~llc~d emborlimPnt an e~ten~ion arm 112 connPct~ each pawl 106 to the push buttons 50a-c. The pawls 106 are p.~r~l~bly pivotally connectPcl to the extPn~ion arms 112 as by pivot pin 118. Each pawl 106 i ~ d~ s an eng~gPmPnt portion 120 which is adapted to engage an elong~tPll ratchet member 124.
The ratchet member 124 can have plurality of ratchet teeth 128 for engagement with the engagement portion 120 of the pawls 106 (Fig. 4). Biasing structure such as a ratchet return spring 132 is adapted to urge the ratchet mPmbers 124 toward the respective push buttons CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 50a-c. The ratchet return spring 132 can be secured by mounting pins 136 fixed to the housing 92 and to mounting pins 140 on the ratchet members 124.
Detents 144 are provided to retain each ratchet member 124 against the force of the ratchet return spring 132 following movement of the ratchet member 124 by the pawl 106.
The detents 144 can include engagement portions 148 which are adapted to engage the teeth 128 of the ratchet members 124. The detents 144 can be pivotally mounted to the housing 92 by suitable structure such as pivot pins 152.
The pawls 106 and detents 144 preferably are biased into engagement with the ratchet members 124 so as to prevent slippage. One or more biasing springs, such as the biasing spring 156, can be provided to pe~ ll this function. The biasing spring 156 can have spring arms 158, lS9 which contact the pawls 106 and detents 144. The biasing spring 156 can be mounted in suitable fashion, such as to the mounting posts 160.
The pawls 106 and ratchet teeth 128 are configured according to known ratchet constructions so as to provide for engagement during a downward stroke of the push buttons lS 50a-c, and slippage of the pawl 106 past the ratchet teeth 128 during the return stroke of the push buttons 50a-c. Return of the push buttons 50a-c is accomplished by push button return springs 164 associated with each of the push buttons 50a-c, which are adapted to bias the push buttons 50a-c away from the ratchet members 124. The detents 144 are constructed in known fashion so as to engage the ratchet members 124 oppositely to the pawls 106, such that the ratchet teeth 128 can move past the detents 144 when the ratchet members are moved by the pawls 106.
Structure may be provided to guide the sliding movement of the ratchet members 124 and the pawls 106. In one embo~limçn~ rails 168 are provided with the housing 92 and are adapted to slidably engage a groove 170 formed in a back surface of each ratchet m ~m bçr WO 96)41997 PCT/US96/10089 124. Grooves 172 can be formed in the housing 92 for guiding the movement of the ratchet members. Pawl guides 176 can also be provided with the housing 92 to guide the motion of the pawls 106. Ratchet stops 180 can be provided to limit the movement of the ratchet mPmbçrs 124 in responce to the biasing of the ratchet return springs 132.
Key-way carriers l90a-c are ~c$o~ ted with each of the ratchet mPmhers 124 and adapted to move with movement of the ratchet mem~prs 124. In a ~ felled embo-lim~ont the key-way carriers 190 are directly engaged to the ratchet members 124, such as by tongue 192 and groove 193 construction. Each key-way carrier 190a-c includes a ~ e.;li~/e key-way 194a-c, which can be formed as a notch or groove therein.
A lock slide 200 is operatively conn~cted to the engagement portion 46 and can extend through a suitable opening 204 in the housing 92. The lock slide 200 inrlndes keys 206a-c which, when assembled, are positioned subst~nti~lly ~ acçnt to respective key-way carriers l90a-c. The lock slide 200 and keys 206a-c are ju~c~osed to the key-way carriers l90a-c such that transverse movement of the lock slide 200 relative to the key-way carriers lS l90a-c is bloclced by contact between the keys 206a-c and the key-way carriers l90a-c.
The key-ways 194a-c are ~limpncioned to accept the keys 206a-c. ~lignm~nt of thekey-ways 194a-c with the keys 206a-c is accomplished by de~ressillg the ~e,pecli~e push buttons 50a-c the a~ ulJliate number of times Cull~ onding to the position of the key-ways 194a-c on the respective key-way carriers l90a-c. A key-way 194 that is pocitioned nearer to the end of the ratchet m~mber 124 that is closest to the le~ec~ e push button S0 will require more op~r~tionc of the push button 50 in order to move the ratchet m~mber 124 and ~coc;~ted key-way carrier 190 a snffifi~nt ~lict~nre to align the key-way 194 with the respective key 206. Different positions of the key-way 194 on the key-way carrier 190 will require more or fewer operations of the push button S0. Accordingly, the relative CA 02221482 1997-12-0~
poci~io2ling of the key-ways 194a-c on the resl.e~ ,re key-way carriers l90a-c collespollds to a combination n-o~eSc~ry to align all of the key-ways 194a-c with the keys 206a-c, so as to permit transverse movement of the keys 206a-c into the key-ways 194a-c, and co"~ponding movement of the lock slide 200. The engagement portion 46 will move with S the lock slide 200 to the "llnloçk~1" position.
A lock slide biasing spring 210 can be provided to urge the lock slide 200 to the unlocked position in which the keys 206a-c are urged into the key-ways 194a-c. The biasing spring 210 can be mounted to the lock slide 200 at a mounting post 214, and can be engaged to a portion of the housing at a post 218 (Fig. 4).
Reset structure is provided for retuming the ratchet members 124 to an initial position, which will move the key-ways 194 out of ~lignm~nt with the keys 206 to lock the lock 40, and so that the combination can be entered from a concictçnt starting point. The reset structure can engage the pawls 106 and detents 144 to move them out of engagement with the ratchet members 124. The ratchet return springs 132 will move the ratchet membçrs 124 to an initial position defined by the ratchet stops 180. A reset slide 220 can be provided with a plurality of reset arms 222. The reset slide 220 is so constructed that, when assembled, the reset arrns 222 are ju~posed to the pawls 106 and detents 144, which extend somewhat out of the plane of the ratchet m~mh~rs 124. The reset slide 220 is slidably disposed within the lock, and can be supported by a portion 226 which is slidably eng~ged 20 in a slot 230 formed in the housing 92. A slot 234 can be provided to receive a mounting screw 238, which engages a threaded socket 240 in the housing 92 so as to provide slidable engagement of the reset slide 220 to the housing 92. A reset button 248 of the reset slide 220 can extend out of an opening 250 in the housing 92 for manipulation by the O~ld~Ol.
Sliding movement of the reset slide 220 will cause contact between the reset arms 222 and CA 02221482 1997-12-0~
W O 96141997 PCT~US96/10089 the pawls 106 and detents 144 to move the pawls 106 and detents 144 out of çng~gemPnt with the ratchet teeth 128 of the ratchet members 124.
In operation, when the lock slide 200 is in the locked position, the engagement portion 46 will be positioned so as to prevent movement of the safety 34 from the "unsafe"
5 position. Keys 206a-c abut the ,e~e~ e key-way carriers l90a-c such that movement of the lock slide 200 to the unlocked position is not possible. Upon operation of the re~.~e~ e push buttons 50a-c, the key-ways 194a-c are aligned with the keys 206a-c. The lock slide 200 is urged by the lock slide spring 210 such that the keys 206a-c are moved into the ~ uecLi~/e key-ways 194a-c. The lock slide 200 and engagement portion 46 thereby are 10 pel-l~iLIed to move from the locked position to the unlocked position, p~ ing movement of the safety 34 to the "unsafe" position, and operation of the firearm. T ocking of the firearm can be accompli~hP~ by m~ml~lly moving the eng~PmPnt portion 46 and lock slide 220 to the locked position in which the keys 206a-c are out of Png,.gPmPnt with the key-ways 194a-c. The lock slide 220 must be held against the biasing of the lock slide spring 210, so 15that ~rid~p-nt~l locking is avoided. Movement of the reset button 248 and reset slide 220 will cause the reset arms 222 to move the ratchet pawls 106 and the detents 144. This will permit movement of the ratchet mpmbers 124 and ~soci~ted key-way carriers l90a-c to the initial position in which movement of the keys 206a-c is blocked by the key-way carriers l90a-c. This will lock the lock 40 and will also position each of the ratchet members 124 20 at the initial position defined by the ratchet stops 180 for subsequent entP-ing of the combination.
~ Movement of the pawls 106 and detents 144 out of Pn~Pmpnt with the ratchet members 124 prior to the completion of the movement of the keys 206a-c out of the e~e;Live key-ways 194a-c can result in dr~.gp:ing of one or more of the keys 206a-c against CA 02221482 1997-12-0~
W O 96/41997 PCT~US96/10089 sides of the l- s~e~Li~e key-way carriers 190a-c. This will impede the return of the key-way carrier 190 and res~ /e ratchet mP~nb.or 124 to the initial position during the reset function. The subsequent release of the reset button 248 will cause the ratchet pawls 106 and detents 144 to engage the respective ratchet member 124, which may not have returned fully S to the initial position because of the dragging against the keys 206. Entering of the a~r~liate combination will be confused because the ratchet m~mbçr 124 and key-way carrier 140 will not be in the true starting position. It is therefore desirable to provide structure to ensure that the reset button 248 is not operable until the lock slide 200 and keys 206a-c are completely out of engagement with key-way carriers l90a-c.
A pivoting reset stop lever 256 can be provided and can be pivotally secured to the housing 92 as by a mounting pin 260. A spring 262 biases the reset stop lever 256 into engagement with a shoulder 266 on the reset slide 220. Completion of the movement of the lock slide 200 to the locked position causes contact between the lock slide 200 and the reset stop lever 256 so as so pivot the lever out of engagement with the reset slide 220. The reset slide 220 can then be operated to reset the position of the ratchet members 124.It is also desirable that structure be provided to urge the lock slide 200 completely out of engagement with the key-way carriers l90a-c during the reset fun~tio~ The lock slide spring 210 may otherwise cause some contact between the keys 206a-c and the key-way carriers l90a-c.

The reversing lever 270 inC~ dçs a pin 271 that is cont~ted by an elongated slot 272 on the reset slide 220 when the reset slide is moved during the reset operation. The contact will pivot the reversing lever 270 and cause a shoulder 282 of the reversing lever 270 to contact a shoulder 286 of the lock slide 200 to urge the lock slide 200 and keys 206a-c securely out of engagement with the key-way carriers l90a-c.

W ~ 9614~997 PCTGUS96/10089 The key-way carriers 190 can include alternate key-ways 290 subst~nti~lly on a side of the key-way carrier 190 o~o~ite the key-way 194. The f~tenin~ structure such as the tongue 192 and groove 193 is such that the key-way carrier 190 can be inverted to face the ~ltern~tP key-way 290 to the lock slide 200 and keys 206. The alternate key-way 290 can 5 be at a different position along the key-way carrier 190 such that inversion of the key-way carrier 190 will result in ~1tP~tioll of the combination nP~ç~ y to align the alternate key-way 290 with the respective key 206 to open the lock. The combination can thereby be readily changed if it becomes known to un~-lthorized users.
It is preferable that structure be provided to prevent the removal of the lock itself by 10 unauthorized users and, as stated earlier, a catch 88 on the adaptor 58 can be aligned with a cooperating catch 302 on the lock housing 92. A portion 298 of the lock slide 200 moves behind the catch 88 and in front of the catch 302 when the lock slide 200 is in the locked position. The adaptor 58, lock slide 200, and housing 92 will thereby be interconnected to secure the lock 40 to the adaptor 58 when the lock 40 is in the locked position. Further, the 1~ lock housing 92 covers and prevents access to the mounting screw 62, which secures the adaptor 58 to the frame 24. The intelcollllP,cting structure provides a construction whereby the lock 40 cannot be removed from the hand gun when the lock 40 is in the locked position.
The principles ~ closP~I herein can be applied to locks having dirre.c;-lt co~ onent configurations. For example, it is possible to construct a lock by which the keys are 20 provided with the ratchet member and the key-ways are provided on the lock slide. Also, the keys and key-ways can be altered to various forms of protrusions and depressions, the ~lignment of which will permit movement of one relative to the other. Other variations as would be a~al~nt to one skilled in the art would also be possible.
An alternative embo~limPnt of the invention is useful for revolvers. Revolvers do not CA 02221482 1997-12-0~
include an external safety mPrh~ni~m, and accordingly, another portion of the firing me~h~ni~m must be operatively engaged in the locked position to prevent operation of the firearm. Figs. 8-11 depict such an embo-liment of the invention for a revolver 306. In this embo~imPnt, a lock 310 is provided with an engagement portion 314. The lock 310 can be similar in construction to the lock 40 described above, or can be made according to a dirrt;lel~l construction, inc~ ling locks that are not combination locks.
Operation of the firearm 306 requires rearward pivoting of a h~mmer 308 upon squeezing of a trigger 312. A h~mmer stirrup 316 is engaged to the h~mmer 308 according to known firearm constructions. A h~mmer return spring 318 is provided to propel the h~mmPr stirrup 316 and h~mmPr 308 during firing of the weapon. An end 319 of theh~mmPr stirrup 316 in some firearm constructions extends into an opening 326 of the frame 330 of the firearm.
An adaptor 320 can be provided and secured to the firearm 306 by suitable f~tPning structure.
