Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
A combination locking assembly comprising: push button panel means for containing a numeric pad of push buttons and presenting the push buttons for manual actuation, said panel means having tines corresponding to each of said push buttons extending away from a back side of said panel means; combination means for maintaining a selected combination, said combination means comprising a plurality of rotatable combination interposers positioned so as to engage and be rotated about an axis by said tines when said push buttons are depressed; and a combination changing assembly comprising a panel positioned so as to pivot in a first direction and urge said combination interposers in a single direction of rotation from a partially turned position to a first incorrect position and erase a previously selected combination from said combination means, and, subsequently to pivot in a second direction and urge a selected few of said combination interposers to a second correct position.
Claim 2
Dependent Claim
154 words
A combination locking assembly comprising: push button panel means for containing a numeric pad of push buttons and presenting the push buttons for manual actuation, said panel means having tines corresponding to each of said push buttons extending away from a back side of said panel means; combination means for maintaining a selected combination, said combination means comprising a plurality of rotatable combination interposers positioned so as to engage and be rotated about an axis by said tines when said push buttons are depressed; and a combination changing assembly comprising a panel positioned so as to pivot in a first direction and urge said combination interposers in a single direction of rotation from a partially turned position to a first incorrect position and erase a previously selected combination from said combination means, and, subsequently to pivot in a second direction and urge a selected few of said combination interposers to a second correct position.
Claim 3
Dependent Claim
25 words
An assembly as in claim 1, further comprising: lever means operatively connected to said panel for pivoting said panel in said first and second directions.
Claim 4
Dependent Claim
33 words
An assembly as in claim 2, further comprising: axially aligned non-rotatable spacer means positioned between adjacent ones of said plurality of combination interposers for separating the rotating displacements of each of said interposers.
Claim 5
Dependent Claim
30 words
An assembly as in claim 2, further comprising: pivoting cover means for covering said combination changing assembly including fastener means for prevention of unauthorized access to said combination changing assembly.
Claim 6
Dependent Claim
138 words
A combination lock assembly comprising: a push button panel having front and back sides and push buttons extending therethrough, each of said buttons having front and back ends and having push bars extending from said back end, said push bars having ramped surfaces on an end thereof remote from said push button; advance bar means for engaging and being displaced by said ramped surfaces when said push buttons are depressed, said advance bar means having a plurality of arms extending therefrom and positioned so as to engage said ramped surfaces; wherein, said respective arms and ramped surfaces engage and displace said advance bar to a position such that additional push buttons are prevented from being depressed when said ramped surface of additional push buttons jam against end portions of said ramped arms of said displaced advance bar means.
Claim 7
Dependent Claim
138 words
A combination lock assembly comprising: a push button panel having front and back sides and push buttons extending therethrough, each of said buttons having front and back ends and having push bars extending from said back end, said push bars having ramped surfaces on an end thereof remote from said push button; advance bar means for engaging and being displaced by said ramped surfaces when said push buttons are depressed, said advance bar means having a plurality of arms extending therefrom and positioned so as to engage said ramped surfaces; wherein, said respective arms and ramped surfaces engage and displace said advance bar to a position such that additional push buttons are prevented from being depressed when said ramped surface of additional push buttons jam against end portions of said ramped arms of said displaced advance bar means.
Claim 8
Dependent Claim
28 words
An assembly as in claim 5, wherein: said push bars further comprise a pair of tines extending therefrom and said advance bar means extends vertically between said tines.
Claim 9
Dependent Claim
42 words
An assembly as in claim 6, further comprising: combination means for maintaining a selected combination comprising a plurality of rotatable combination interposers positioned so as to engage and be rotated about an axis by said tines when said push buttons are depressed.
Claim 10
Dependent Claim
66 words
An assembly as in claim 7, further comprising: a combination changing assembly comprising a panel positioned so as to pivot in a first direction and urge said combination interposers in a single direction of rotation from a partially turned position to a first incorrect position and urge a selected few of said combination interposers to a second correct position so as to select a new combination.
Claim 11
Dependent Claim
55 words
An assembly as in claim 5, further comprising: locking ratchet means for selectively locking and unlocking a latching assembly; and secondary advance bar means operatively connected to said advance bar means for transferring the displacement of said advance bar means to said locking ratchet means to urge said locking ratchet means to a displaced location.
Claim 12
Dependent Claim
21 words
An assembly as in claim 9, further comprising: locking pawl means for maintaining the displaced location of said locking ratchet means.
Claim 13
Independent Claim
79 words
A method of changing the combination of a locking combination assembly having a pushbutton keypad, combination setting assembly, and a cover member, comprising the steps of: opening said cover member to enable access to said combination setting assembly, urging a combination setting panel in a first direction to clear the existing combination, entering a desired combination on said pushbutton keypad, and urging said combination setting panel in a second direction to set the desired combination in the combination assembly.
Claim 14
Independent Claim
79 words
A method of changing the combination of a locking combination assembly having a pushbutton keypad, combination setting assembly, and a cover member, comprising the steps of: opening said cover member to enable access to said combination setting assembly, urging a combination setting panel in a first direction to clear the existing combination, entering a desired combination on said pushbutton keypad, and urging said combination setting panel in a second direction to set the desired combination in the combination assembly.
Claim 15
Dependent Claim
117 words
A combination locking assembly, comprising: push button panel means for containing a numeric pad of push buttons and presenting the push buttons for manual actuation, said panel means having tines corresponding to each of said push buttons extending away from a back side of said panel means; combination means for maintaining a selected combination, said combination means comprising a plurality of rotatable combination interposers positioned so as to engage and be rotated about an axis by said tines when said push buttons are depressed; wherein, when said push buttons are depressed, the relative positioning of the actuating tine and the combination interposer is fixed from the moment actuation of the pushbutton occurs until the pushbutton is released.
Claim 16
Dependent Claim
117 words
