         [0072]    It is seen from a consideration of FIG. 8A, that the latch  526 , bolts  540  and electrically driven bolt  554  are fully extended when a lock handle  556  is in a generally horizontal position, a key  558  in a cylinder  560  is in a first rotational orientation, here shown tilted to the left, and driver  552  is suitably electrically actuated.  
         [0073]    It is seen from a consideration of FIG. 8B, that when key  558  in cylinder  560  is in a second rotational orientation, here show tilted to the right, the lock handle  556  remains in its generally horizontal position and driver  552  remains suitably electrically actuated, bolts  540  are fully retracted and bolt  554  remains extended.  
         [0074]    It is seen from a consideration of FIG. 8C, that when key  558  in cylinder  560  is in its first rotational orientation, here shown tilted to the left, the lock handle  556  remains in its generally horizontal position and driver  552  is deactuated, bolts  540  are fully extended and bolt  554  is retracted.  
         [0075]    It is seen from a consideration of FIG. 8D, that when key  558  in cylinder  560  is in a second rotational orientation, here shown tilted to the right, the lock handle  556  remains in its generally horizontal position and driver  552  is deactuated, bolts  540  and bolt  554  are fully retracted.  
         [0076]    It is seen from a consideration of FIG. 8E, that when key  558  in cylinder  560  is in a second rotational orientation, here shown tilted to the right, the lock handle  556  is in a generally downwardly tilted position and driver  552  is deactuated, bolts  540  and bolt  554  are fully retracted and latch  526  is fully retracted.  
         [0077]    Reference is now made to FIGS. 9A, 9B,  9 C and  9 D, which are simplified pictorial illustrations of another type of an enhanced action partially electrically operated and partially mechanically operated Lock assembly constructed and operative in accordance with a preferred embodiment of the present invention in four alternative operative orientations.  
         [0078]    As seen in FIGS. 9A, 9B,  9 C and  9 D, an enhanced action assembly  610  is mounted, as by screw fasteners or rivets  612 , onto an outer edge of a conventional lock, here a mortise lock  613 .  
         [0079]    The enhanced action assembly  610  preferably comprises an assembly support  614  including a mounting panel  616  which is mounted by screw fasteners or rivets  612  onto the outer edge of the mortise lock  613  and which is preferably integrally formed with a side panel  618 , which extends outwardly from mounting panel  616  and is preferably integrally formed therewith.  
         [0080]    A latch elongating assembly  620  is preferably mounted, as by a set screw  622 , onto a latch shaft  624  of the mortise lock  613 . A latch  626 , here a multi-element latch, is mounted to an outer facing end of assembly  620 .  
         [0081]    A bolt elongating shaft assembly  630  is preferably mounted, as by set screws  632 , onto a bolt  634  of the mortise lock  613 . A multiple bolt assembly  636  is mounted to an outer facing end of assembly  630 . Multiple bolt assembly  636  preferably comprises a base  638  onto which are mounted a plurality of bolts  640 . An edge plate  642  is provided for mounting on an edge of a door (not shown) and is suitably apertured with mounting screw mounting apertures  644 , a latch aperture  646  and bolt apertures  648 .  
         [0082]    An electrically operated auxiliary latch retraction assembly  650 , typically comprising a driver  652 , such as a solenoid which positions a hinged lever  654 , provides electrically controllable latch retraction.  
         [0083]    It is seen from a consideration of FIG. 9A, that both the latch  626  and the bolts  640  are fully extended when a lock handle  655  is in a generally horizontal position, a key  656  in a cylinder  658  is in a first rotational orientation, here shown tilted to the left, and driver  652  is not actuated.  
         [0084]    It is seen from a consideration of FIG. 9B, that when key  656  in cylinder  658  is in a second rotational orientation, here shown tilted to the right, bolts  640  are fully retracted.  
         [0085]    It is seen from a consideration of FIG. 9C, that both the latch  626  and the bolts  640  are fully retracted when lock handle  655  is in a generally downwardly tilted position and when key  656  in cylinder  658  is in a second rotational orientation, here shown tilted to the right.  
         [0086]    It is seen from a consideration of FIG. 9D, that both the latch  626  and the bolts  640  are fully retracted even when lock handle  655  is in a generally downwardly tilted position and when key  656  in cylinder  658  is in a second rotational orientation, here shown tilted to the right, provided that driver  652  is actuated, causing lever  654  to retract latch  626 .  
         [0087]    Reference is now made to FIG. 10, which is a simplified pictorial illustration of another type of enhanced action multiple direction lock assembly constructed and operative in accordance with a preferred embodiment of the present invention. In the embodiment of FIG. 10, an enhanced action assembly  710  is mounted, as by screw fasteners or rivets  712 , onto an outer edge of a known multiple bolt mortise lock  713 , here, Model 265 commercially available from Mul-T-Lock Ltd. of Yavne, Israel.  
         [0088]    The enhanced action assembly  710  preferably comprises an assembly support  714  including a mounting panel  716  which is mounted by screw fasteners or rivets  712  onto the outer edge of the mortise lock  713  and which is preferably integrally formed with a side panel  718 , which extends outwardly from mounting panel  716  and is preferably integrally formed therewith.  
         [0089]    A latch elongating assembly  720  is preferably mounted, as by a set screw  722 , onto a latch shaft  724  of the mortise lock  713 . A latch  726 , here a multi-element latch, is mounted to an outer facing end of assembly  720 .  
         [0090]    A bolt elongating shaft assembly  730  is preferably mounted onto a bolt of the mortise lock  713 . A multiple bolt assembly  736  is mounted to an outer facing end of assembly  730 . Multiple bolt assembly  736  preferably comprises a base  738  onto which are mounted a plurality of bolts  740 . An edge plate  742  is provided for mounting on an edge of a door (not shown) and is suitably apertured with mounting screw mounting apertures  744 , a latch aperture  746  and bolt apertures  748 .  
         [0091]    It is seen from a consideration of FIG. 10, that the latch  726  is fully extended and the bolts  740  are fully retracted when a lock handle  750  is in a generally horizontal position and when a key  752  in a cylinder  754  is tilted to the right as shown.  
         [0092]    It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the various features described hereinabove as well as variations and modifications which would occur to persons skilled in the art upon reading the specification and which are not in the prior art.
