Abstract
Abstract A portable lock box is disclosed that is formed from an outer four-sided hollow tubular elongated structure having a rectangular cross-section with an elongated slot form transverse to the housing and an inner housing having closed end U-shaped members in overlapping leg configuration secured to each other in which one of the legs has a cooperating elongated slot to admit the latch member of a cam lock that is secured to one of the closed ends of the U-shaped members. A tray is provided to secure the valuables within the inner housing and a looped steel cable extends through a pair of slots formed in the edge of one of the closed ends of the U-shaped members.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
An improved portable lock box comprising: (a) a four sided hollow tubular elongated structure, having a rectangular cross-section and a pair of open ends, one of said sides having a first elongated slot formed therein transverse to an axis defined by said elongated structure; (b) a pair of closed end U-shaped members having overlapping leg configurations, with one leg having a second elongated slot cooperating with said first elongated slot and formed therein transverse to said axis defined by said elongated structure; (c) a plurality of securing mechanisms securing said legs of said pair of U-shaped members to each other to form a second four sided tubular elongated structure having open sides and a hollow rectangular cross section of smaller dimensions than said first four sided structure; (d) a tray disposed within said pair of U-shaped members for containing valuables; and (e) a cam lock secured in one of the closed ends of said U-shaped members having a latch member extending through and cooperating with, said first and second elongated slots to create a locking mechanism for locking said second four sided tubular elongated structure to said first four sided tubular structure when inserted to a proper depth within said first four sided tubular elongated structure.
Claim 2
Dependent Claim
206 words
An improved portable lock box comprising: (a) a four sided hollow tubular elongated structure, having a rectangular cross-section and a pair of open ends, one of said sides having a first elongated slot formed therein transverse to an axis defined by said elongated structure; (b) a pair of closed end U-shaped members having overlapping leg configurations, with one leg having a second elongated slot cooperating with said first elongated slot and formed therein transverse to said axis defined by said elongated structure; (c) a plurality of securing mechanisms securing said legs of said pair of U-shaped members to each other to form a second four sided tubular elongated structure having open sides and a hollow rectangular cross section of smaller dimensions than said first four sided structure; (d) a tray disposed within said pair of U-shaped members for containing valuables; and (e) a cam lock secured in one of the closed ends of said U-shaped members having a latch member extending through and cooperating with, said first and second elongated slots to create a locking mechanism for locking said second four sided tubular elongated structure to said first four sided tubular structure when inserted to a proper depth within said first four sided tubular elongated structure.
Claim 3
Dependent Claim
42 words
The structure set forth in claim 1 including: (f) a latch member cover secured to said four sided tubular elongated structure and disposed over said first elongated slot to permit said latch member to operate but not be exposed to external forces.
Claim 4
Dependent Claim

The structure set forth in claim 1 including: (g) a pair of slots formed in the edge of one of said closed ends of said U-shaped members; (h) a looped steel cable extending through said pair of slots and adapted to be secured around an immovable object; and (i) a metal stop sleeve secured about each end of said cable, and disposed inside said closed ends of said U-shaped members.
Claim 5
Dependent Claim
28 words
The structure set forth in claim 1 wherein said plurality of securing mechanisms are hardened steel rivets passing through both thicknesses of said pair of overlapping leg configurations.
