Abstract:
1. A collapsible lantern, comprising: a lantern housing having a front side and a rear side and a receiving cavity defined between said front side and said rear side; an illumination unit provided in said receiving cavity of said lantern housing for generating illumination; and a collapsible arrangement, which comprises: a tubular lens body which has a light cavity and a light admissible sidewall, and is movably extended from said front side of said lantern housing to move between a collapsed position and a lantern position; and a light controlling cap assembly having a light window provided at a front end portion of said tubular lens body and aligned with said illumination unit, wherein said light controlling cap assembly comprises a light shelter operatively mounted in front of said light window to selectively cover said light window, wherein said light shelter is selectively moved to close said light window at one of said collapsed position and said lantern position, wherein when said tubular lens body is at said collapsed position, said tubular lens body is moved into said lantern housing so as to allow said light controlling cap assembly to overlappedly rest on said front side of said lantern housing, while said light shelter is moved to open said light window for allowing said illumination generated by said illumination unit to reach an exterior of said lantern housing through said light window, wherein when said tubular lens body is at said lantern position, said tubular lens body is moved frontwardly out of said lantern housing while said light shelter is moved to close said light window so that said illumination generated by said illumination unit is able to reach an exterior of said lantern housing through said light admissible sidewall of said tubular lens body, wherein said illumination unit comprises a LED illuminator mounted in said receiving cavity and at a front portion of said lantern housing for generating illumination, wherein said tubular lens body is moved to align with said LED illuminator, wherein said lantern housing has a battery compartment defined in said receiving cavity at a rear portion of said lantern housing for receiving at least one battery, wherein said tubular lens body of said collapsible arrangement is made of light admissible material for defining said light cavity and said light admissible sidewall, wherein said tubular lens body has an octagonal cross section so that there are eight light admissible sidewalls forming said tubular lens body, wherein said tubular lens body is slidably mounted on said lantern housing for moving between said collapsed position and said lantern position, wherein said tubular lens body is mounted in said receiving cavity of said lantern housing in a slidably movable manner, wherein said tubular lens body is slidably moved from said collapsed position to said lantern position and vice versa by moving said light controlling cap assembly attached on a front edge portion of said tubular lens body, wherein a longitudinal length of said tubular lens body is slightly longer than that of said lantern housing so that when said tubular lens body is at said collapsed position, said tubular lens body is capable of receiving in said lantern housing for reducing an overall size of said lantern, wherein when said tubular lens body is at said lantern position, said tubular lens body is slid out of said lantern housing and an overall size of said lantern is substantially increased for providing uniform illumination to an exterior of said lantern, wherein said lantern housing further comprises a base member provided at a rear portion of said lantern housing for providing an extended surface area to allow said lantern housing to stand on a ground surface, wherein said lantern housing further comprises a front supporting member provided at a front end portion of said lantern housing, wherein said light controlling cap assembly is moved to rest on said front supporting member when said tubular lens body is at said collapsed position, wherein said light controlling cap assembly is circular in cross section, wherein said light shelter comprises a plurality of shelter members spacedly and movably extended from a sidewall of said light window for selectively closing and opening said light window, wherein said light controlling cap assembly comprises a supporting unit mounted at said top edge portion of said tubular lens body, a shelter actuation member rotatably mounted on said supporting unit with respect to said supporting unit, and a cap member mounted above said supporting unit and said shelter actuation member, wherein each of said supporting unit, said shelter actuation member and said cap member has a central through slot formed thereon to constitute said light window of said light controlling cap assembly, wherein said cap member is also rotatably mounted to said supporting unit while said shelter actuation member and said light shelter are sandwiched between said cap member and said supporting unit.
