Patent number: 8931832Abstract: A swivel stool includes a foldable leg arrangement having a plurality of leg frames pivotally connected to each other to form a receiving cavity defined within the leg frames, a seat unit including a seat frame and a back frame pivotally connected to the seat frame. The swivel stool is arranged to operate between a folded position and an unfolded position, wherein in the folded position, the back frame is overlappedly folded toward the seat frame, while the seat unit is pivotally and downwardly folded with respect to the leg frames to receive into the receiving cavity of the foldable leg arrangement, wherein in the unfolded position, the seat unit is pivotally and upwardly unfolded with respect to the leg frames while the back frame is pivotally unfolded with respect to the seat frame for allowing a user to sit on the seat unit.Type: GrantFiled: May 25, 2012Date of Patent: January 13, 2015Inventor: Fermi Chi Hung Lau

Patent number: 8851702Abstract: A collapsible lantern includes a lantern housing, an illumination unit and a collapsible arrangement. The latter includes a tubular lens body and a light controlling cap assembly. The tubular lens body is movably extended from the front side of the lantern housing to move between a collapsed position and a lantern position. The light controlling cap assembly has a light window and includes a light shelter, in such a manner that when the tubular lens body is at the collapsed position, the tubular lens body is moved into the lantern housing while the light shelter is driven to open the light window for allowing illumination to reach an exterior of the lantern housing. When the tubular lens body is at the lantern position, the tubular lens body is moved out of the lantern housing while the light shelter is driven to close the light window.Type: GrantFiled: March 21, 2012Date of Patent: October 7, 2014Inventor: Fermi Chi Hung Lau

Patent number: 8714788Abstract: A spotlight includes a main housing, an illumination device received in the main housing and an angle adjusting arrangement. The angle adjusting arrangement includes an adjustable handle and a locking mechanism. The adjustable handle, having a predetermined curvature, is outwardly extended and rotatably mounted to the main housing and is arranged to selectively and rotatably move with respect to the main housing so as to selectively adjust an angle of inclination between the adjustable handle and the main housing. The locking mechanism is coupled between the adjustable handle and the main housing for selectively retaining the adjustable handle at a predetermined angle of inclination with respect to the main housing so that when the adjustable handle is held by a user, the illumination device is arranged to generate the illumination at a predetermined orientation corresponding with the angle of inclination of the adjustable handle.Type: GrantFiled: March 21, 2012Date of Patent: May 6, 2014Inventor: Fermi Chi Hung Lau

Publication number: 20130306121Abstract: A hunting blind includes a body assembly and a roof assembly. The body assembly includes a body frame defining a receiving cavity, and a body blind embedding the body frame for hiding a hunter in the receiving cavity. The roof assembly includes a roof frame detachably attached on the body frame, and a roof blind provided on the roof frame to operate between a hiding mode and a hunting mode, wherein in the hiding mode, the roof frame and the roof blind are attached on the body frame so as to conceal the receiving cavity, wherein in the hunting mode, the roof assembly is operated to create a roof opening for communicating the receiving cavity with an exterior of the hunting blind, so that a hunter may normally hide in the receiving cavity and expose himself through the roof opening for hunting a predetermined target.Type: ApplicationFiled: May 21, 2012Publication date: November 21, 2013Inventor: Fermi Chi Hung Lau

Patent number: 8449132Abstract: A head light includes a light core, an assembling accessory and a hear gear. The light core includes a light source for generating light. The assembling accessory includes a front casing and a back casing and defines a core cavity within the front and back casings to receive the light core, wherein the front casing has a light window aligning with the light source such that when the light core is supported within the core cavity, the light source is controllably activated to generate the light through the light window, wherein the assembling accessory is a building part that the assembling accessory is adapted for not only being pieced together with the light core for creating a particular ornamental design and light effect of the head light, but also being disassembled to mix and match with an alternated light core for producing different light effects.Type: GrantFiled: April 22, 2009Date of Patent: May 28, 2013Inventor: Fermi Chi Hung Lau
