Abstract
Abstract This invention relates to a protective shield for coin box locks comprising a housing mounted in front of the latter that denies all direct axial access to the key slot in favor of a remotely located key-receiving opening at right angles thereto. It also encompasses a remotely-actuated right-angle-driven key operative to open the lock from a position outside the housing and displaced to one side of the axis of lock rotation. The invention further encompasses a push-pin and pivoted lever for actuating same from a remote position that cooperate with one another and with the wall of the housing facing the lock upon actuation to insert the key in the latter.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
191 words
Anti-probe apparatus for use with a lock of the type actuated by insertion of a key into a keyway followed by rotation thereof which comprises in combination: guard means defining a tunnel having an opening in the side thereof intermediate its ends sized to provide access to the keyway when attached so as to register therewith and a second opening at one end displaced to one side of said access opening and disposed at right angles thereto; and, lock-actuating means including a housing insertable into said tunnel through the open end thereof, said housing being sized for relative transverse movement therein between a retracted position remote from the access opening in the side thereof and an extended position in close proximity to the latter, a key operative to actuate the lock journalled for rotation in the housing in position to enter the keyway upon relative transverse movement of said housing from its retracted into extended position, right angle drive means within said housing connected to said key and operative upon actuation to rotate same, and actuating means accessible through the open end of the tunnel operatively connected to said drive means.
Claim 2
Dependent Claim
191 words
Anti-probe apparatus for use with a lock of the type actuated by insertion of a key into a keyway followed by rotation thereof which comprises in combination: guard means defining a tunnel having an opening in the side thereof intermediate its ends sized to provide access to the keyway when attached so as to register therewith and a second opening at one end displaced to one side of said access opening and disposed at right angles thereto; and, lock-actuating means including a housing insertable into said tunnel through the open end thereof, said housing being sized for relative transverse movement therein between a retracted position remote from the access opening in the side thereof and an extended position in close proximity to the latter, a key operative to actuate the lock journalled for rotation in the housing in position to enter the keyway upon relative transverse movement of said housing from its retracted into extended position, right angle drive means within said housing connected to said key and operative upon actuation to rotate same, and actuating means accessible through the open end of the tunnel operatively connected to said drive means.
Claim 3
Dependent Claim
96 words
The combination as set forth in claim 1 which includes a lever pivotally attached to the housing for rockable movement about an axis intermediate its ends, said lever having one end thereof accessible outside the end of the tunnel and its other end terminating inside the latter on the opposite side of the housing from the key, and said accessible end being operative upon movement thereof in the direction in which the key enters the keyway to force its inner end against the tunnel wall facing the latter thus biasing the housing into its extended position.
Claim 4
Dependent Claim
52 words
The combination as set forth in claim 1 in which: means defining an abutment effective to limit the degree of penetration of the housing blocks the other end of the tunnel, said abutment-forming means and housing cooperating with one another upon insertion of the latter to position the key opposite the keyway.
Claim 5
Dependent Claim
60 words
The combination as set forth in claim 1 in which: both the tunnel and housing are of rectangular cross section with the latter being dimensioned to telescope into the former so as to permit relative transverse movement in the direction of key movement into the keyway while preventing essentially all relative transverse movement in a direction normal to the latter.
Claim 6
Dependent Claim
27 words
The combination as set forth in claim 1 in which: the guard means is opaque and shaped to permit only limited oblique visual access to the keyway.
Claim 7
Dependent Claim
22 words
The combination as set forth in claim 1 in which: the right angle drive means comprises a worm and pinion gear train.
Claim 8
Dependent Claim
31 words
The combination as set forth in claim 1 in which: wall means defines a closure for the other end of the tunnel effective to deny both physical and visual access thereto.
Claim 9
Dependent Claim
40 words
The combination as set forth in claim 1 in which: the interior dimensions of the tunnel are selected such as to effectively deny direct manual access to the keyway of the nature required to insert and turn a key therein.
Claim 10
Dependent Claim
74 words
The combination as set forth in claim 2 in which: the lever is pivoted inside the housing, a push-pin is mounted within the wall of the housing remote from the lock for reciprocating movement from a retracted position into an extended position engaging said tunnel wall facing the latter, and in which the inner end of the lever becomes operative upon actuation of the accessible end thereof to engage the pin and extend same.
Claim 11
Dependent Claim
79 words
The combination as set forth in claim 6 in which: a shaft is journalled for rotation in the housing about an axis normal to the axis of key rotation displaced to one side thereof, the worm is mounted on said shaft for conjoint rotation therewith, the pinion is mounted on the key in meshed engagement with the pinion, and the actuating means is operatively attached to the end of the shaft accessible through the open end of the tunnel.
Claim 12
Dependent Claim
91 words
The subcombination of a guard for use as a protective cover over a keyway in a key lock forming an integral part of a structure to be protected which comprises: a tubular member permanently attached to the structure to be protected in position covering the keyway, said member defining a tunnel having an opening in the side thereof intermediate its ends registering with said keyway and provide access thereto and a second opening at one end thereof displaced to one side of said access opening and disposed at right angles thereto.
