1. A foldable crate comprises:
[a] a base platform, said base platform comprising:
[1] a pair of longitudinal portions;[2] a pair of flanking portions;[3] at least one structural element, disposed adjacently to said longitudinal portions of said base platform;[4] at least one structural element, disposed adjacently to said flanking portions of said base platform; [b] a pair of longitudinal sidewalls, each one of said longitudinal sidewalls comprises at least one structural element, configured to form a hinged connection with said at least one structural element, disposed adjacently to said longitudinal portion of said base platform; [c] a pair of flanking sidewalls, each one of said flanking sidewalls comprises:
[1] at least one structural element, configured to form a hinged connection with said at least one structural element, disposed adjacently to said flanking portion of said base platform;[2] a tab, configured to serve as a gripping handle;[3] a structured centric recess, essentially surrounding said tab, configured to accommodate a locking mechanism;[4] a pair of channels at a top portion of said flanking sidewall; [d] a pair of locking mechanisms disposed inside flanking sidewalls, each of said locking mechanisms comprises:
[1] an actuator, each one of said actuators is slidable inside said structured centric recess of flanking said sidewalls and comprises:
[i] a pair of sinusoidally shaped driving extensions, wherein said sinusoidally shaped driving extensions embody a shape of an essentially complete sinusoidal cycle, and wherein said sinusoidally shaped driving extensions extend from said actuator at an orientation essentially exceeding a 45 degrees angle;[ii] a pair of connectors furnishing terminal portions of said sinusoidally shaped driving extensions; wherein said connectors are connectable to said sinusoidally shaped driving extensions at an orientation essentially preceding a 45 degrees angle;[iii] a tab essentially congruent to said tab of said flanking sidewall;[2] a pair of locking elements, threaded into said channels at said top portion of said flanking sidewalls; wherein said locking elements are operationally connectable to said connectors, furnishing said terminal portions of said sinusoidally shaped driving extensions;wherein said sinusoidally shaped driving extensions, which embody a shape of an essentially complete sinusoidal cycle, are positioned horizontally, in the direction of translation of said locking elements, wherein upon forceful elevation of said actuator in an upward direction, said sinusoidally shaped driving extensions are compressed and extended in lengths, whereby said locking elements are retracted into said channels, allowing folding said crate;wherein upon release of said forceful elevation, said sinusoidally shaped driving extensions are released and contracted in lengths and said locking elements are consequently protracted from said channels in said flanking sidewalls, into said longitudinal sidewalls; thereby locking said crate assembled. |
