DETAILED DESCRIPTION OF THE INVENTION

[0022] Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0023] In accordance with some embodiments of the present invention, reference is now made to FIG. 1A to 3. FIGS. 1A and 1B show one embodiment of key 10 comprising shaft 22 and grip handle 24, in accordance with of the present invention. Grip handle 24 optionally comprises tab 26 as well as other structural and/or ornamental elements (not shown). In some embodiments grip handle 24 bears part of the composite meaningful indicia (not shown) and/or a hint/lead or question (not shown) related to the meaningful composite indicia, as will be further elaborated infra.

[0024] Key 10 with shaft 22 is configured to operate with a compatible tumbler lock (not shown) comprising an outer casing with a cylindrical hole and the plug with a keyway and series of holes containing key pins and a corresponding spring-loaded driver pin in the outer casing above each key pin in the plug. The compatible tumbler lock (not shown) in accordance with the present invention is preferably promptly programmable, entailing physical accessibility and ability to exchange the aforesaid key pins in the plug and/or corresponding spring-loaded driver pin in the outer casing.

[0025] Shaft 22 of key 10 embodies inferior essentially U-shaped groove 28, extending along the longitudinal centerline on the bottom face of shaft 22. Inferior groove 28 is configured to receive the protruding portion of assembleable key bits 12 to 20, shown in FIG. 2A to 2E.

[0026] Assembleable key bits 12 to 20, shown in FIG. 2A to 2E, embody particular and distinct shapes, forms, heights or sizes configured to respectively match and thereupon operate the key pins (not shown) in the plug (not shown) and consequently the corresponding spring-loaded driver pin (not shown) in the outer casing (not shown) of a compatible tumbler lock (not shown). Additionally to the particular and distinct shape, form, height or size configured to match and operate the key pins (not shown) in the plug (not shown) of a compatible tumbler lock (not shown), assembleable key bits shown in FIG. 2A to 2E bear individual indicia constituents thereon. Thus for instance assembleable key bit 12 shown in FIG. 2A bears an indicium of the Latin letter A, assembleable key bit 14 shown in FIG. 2B bears an indicium of the Latin letter N, assembleable key bit 16 shown in FIG. 2C bears an indicium of the Latin letter S, assembleable key bit 18 shown in FIG. 2D bears an indicium of the Latin letter W, whereas assembleable key bit 20 shown in FIG. 2E bears an indicium of the Latin letter E, etc.

[0027] Assembleable key bits 12 to 20, shown in FIG. 2A to 2E, embody a protruding bottom portion, configured to be received into inferior groove 28 in shaft 22 of key 10. Protruding bottom portion of assembleable key bits 12 to 20, shown in FIG. 2A to 2E, are further configured to be affixed within inferior groove 28 on shaft 22 of key 10. The mechanism affixing assembleable key bits 12 to 20, shown in FIG. 2A to 2E, within inferior groove 28 on shaft 22 of key 10, in a non-limiting manner employs magnetic, frictional and/or mechanic means, such as detents, to achieve the removable affixability of assembleable key bits 12 to 20 in groove 28 on shaft 22.

[0028] As previously mentioned, assembleable key bits shown in FIG. 2A to 2E, bear individual indicia constituents thereon. Each indicium constituent is meaningless, in the sense that each indicium constituent being just a letter, syllable, sign, mark or a part of the entire composite meaningful indicia, shown in a partially composed form in FIG. 3. Similarly, each assembleable key bit is incapable to achieve the mechanical actuation of the compatible tumbler lock (not shown). Only upon correct selection of the right assembleable key bits, from a set comprising a plurality of other assembleable key bits, and proper combination thereof on shaft 22 of key 10, the entire composite meaningful indicia 100, shown in a partially composed form in FIG. 3, is composed so that key 10 is capable to achieve the mechanical actuation of the compatible tumbler lock (not shown).

[0029] In accordance with another embodiment of the present invention, reference is now made to FIG. 4 to 6. FIG. 4 shows another embodiment of key 40 comprising shaft 52 and grip handle 24. Grip handle 24 optionally comprises tab 26 as well as other structural and/or ornamental elements (not shown).

[0030] Shaft 52 of key 40 embodies a pair of parallel cylindrical rods, configured to operate with a compatible tumbler lock (not shown). Parallel cylindrical rods of shaft 52 are configured to be threaded into assembleable key bits 42 to 50, shown in FIG. 5A to 5E.

[0031] Assembleable key bits 42 to 50, shown in FIG. 5A to 5E, embody particular and distinct shapes, forms, heights or sizes configured to respectively match and thereupon operate a compatible tumbler lock (not shown) and bear individual indicia constituents thereon; key bit 42 an indicium A, assembleable key bit 44 bears an indicium N, assembleable key bit 46 bears an indicium S, assembleable key bit 48 bears an indicium W, whereas assembleable key bit 50 bears an E.

[0032] Only upon correct selection of the right assembleable key bits, from a set comprising a plurality of other assembleable key bits, and proper combination thereof on shaft 52 of key 40, the entire composite meaningful indicia 100, shown in a partially composed form in FIG. 3, is composed so that key 40 is capable to achieve the mechanical actuation of the compatible tumbler lock (not shown).

[0033] In some embodiments the shaft of the key configured to operate the compatible tumbler lock (not shown), such as shaft 22 shown in FIG. 1 or shaft 22 shown in FIG. 4, bears part of the composite meaningful indicia (not shown) and/or a hint/lead or question (not shown) related to the meaningful composite indicia.

[0034] In one embodiment the key configured to operate the compatible tumbler lock (not shown) is shaft-less, comprising essentially a handle, while the assembleable key bits comprising an interlocking mechanism, so that the construction of the key is segmental. In such embodiments the shaft of the assembleable key is formed by segmentally connecting assembleable key bits in tandem.

[0035] 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 herein above. Rather the scope of the invention is defined by the claims which follow:
