Abstract
Abstract A portable, auxiliary lock assembly of the type used to secure the conventional or permanently installed lock bolt in its locked position thereby preventing inadvertent admittance through the use of a key or through unauthorized manipulation of the lock mechanism itself. A pair of clamp arms are spaced between the door frame and the edge of the door containing the locking assembly and disposed into firm grasping engagement with the portions of the lock bolt when it is in its locked position. Movement of the lock bolt into its unlocked position is thereby prevented until such bolt is released by the clamp arms of the auxiliary lock assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
An auxiliary lock assembly primarily designed to prevent longitudinal displacement of a conventional lock bolt element, said assembly comprising: frame means dimensioned and configured for placement between door edge and a door frame and including two clamp arms movably interconnected to one another, each clamp arm comprising grasping means formed on correspondingly positioned interior edge portion of each arm in spaced apart relation to one another, closing means interconnected to each clamp arm and disposed to position said clamp arms into and out of grasping engagement with oppositely disposed external surface portions of the lock bolt element, whereby movement of the lock bolt along its own longitudinal axis and into a non-locking position is prevented.
Claim 2
Dependent Claim
115 words
An auxiliary lock assembly primarily designed to prevent longitudinal displacement of a conventional lock bolt element, said assembly comprising: frame means dimensioned and configured for placement between door edge and a door frame and including two clamp arms movably interconnected to one another, each clamp arm comprising grasping means formed on correspondingly positioned interior edge portion of each arm in spaced apart relation to one another, closing means interconnected to each clamp arm and disposed to position said clamp arms into and out of grasping engagement with oppositely disposed external surface portions of the lock bolt element, whereby movement of the lock bolt along its own longitudinal axis and into a non-locking position is prevented.
Claim 3
Dependent Claim
49 words
An auxiliary lock assembly as in claim 1 wherein said clamp arms are disposed, at least in part, in substantially co-planar relation to one another and dimensioned and configured for placement between the door edge and door frame, said grasping means positionable in functional engagement with the lock bolt.
Claim 4
Dependent Claim
44 words
An auxiliary lock assembly as in claim 2 wherein portions of each of said clamp arms having said grasping means formed thereon are positioned in co-planar spaced apart relation to one another and in angularly oriented relation to remaining portions of each clamp arm.
Claim 5
Dependent Claim
43 words
An auxiliary lock assembly as in claim 2 wherein portions of each of said clamp arms having said grasping means formed thereon are positioned in co-planar spaced apart relation to one another, the longitudinal axis of each clamp arm including a multi-angular configuration.
Claim 6
Dependent Claim
56 words
An auxiliary lock assembly as in claim 1 further comprising pivot means movably interconnected between each of said clamp arms and disposed in spaced apart relation from said grasping means and said closing means, and further disposed to cause displacement of each grasping means toward and away from one another upon manipulation of said closing means.
Claim 7
Dependent Claim
35 words
An auxiliary lock assembly as in claim 5 comprising a length element having oppositely disposed ends pivotally attached to one of said clamp arms and disposed opposite said closing means relative to said grasping means.
Claim 8
Dependent Claim
47 words
An auxiliary lock assembly as in claim 1 wherein each of said grasping means comprises adetent portion integrally formed in correspondingly positioned interior edge portions and each further including a substantially uneven periphery disposable in frictional engagement with oppositely disposed external surface portions of the lock bolt.
Claim 9
Dependent Claim
80 words
An auxiliary lock assembly as in claim 1 wherein said closing means comprises a finger element movably attached to one of said clamp arms, bracket means secured to the opposite of said clamp arms and movably mounted on said finger for disposition along the length thereof, whereby movement of said bracket along the length of said finger causes pivotal movement of said clamp arms relative to one another and disposition of said grasping means towards and away from one another.
Claim 10
Dependent Claim
32 words
An auxiliary lock assembly as in claim 8 wherein said bracket includes a nut means and said finger comprises an externally threaded surface having said nut means movable along the length thereof.
Claim 11
Dependent Claim
58 words
An auxiliary lock assembly as in claim 1 further comprising wedge plate means having a thickness at least as great as leading portions of both clamp arms on which said grasping means are formed, said wedge plate means disposable between a door edge and the door jam, whereby space is provided for similar placement of said clamp arms.
