An engine inlet cover and a method for covering an engine inlet are provided. A method for covering an engine inlet includes providing a collapsible cover comprising a connection pin defining an axis; a frame including interconnected arms; and a web. Further, the method includes storing the collapsible cover in a stowed configuration in which the arms are aligned. Also, the method includes rotating the arms from the stowed configuration to an operating configuration in which the arms are radially spaced about the axis, enclosing the frame in the operating configuration with the web to define an interior volume, and placing the cover over the engine inlet.

A cantilever umbrella has an upstanding mast and a cantilever arm adapted to support a canopy. The mast has an interior region defined by a longitudinally extending channel with a longitudinally aligned opening extending from the interior to the exterior of the mast. A carriage resides within the channel and is adapted for travel within the channel. Raising the carriage within the channel causes the cantilever to transition to the open position, and lowering of the carriage causes the cantilever to transition to the closed position.

A cantilevered umbrella assembly with an arcuate guide track comprises a support column, a cantilever arm attached to the support column, and an at least partially arcuate configured guide track attached to the cantilever arm that defines a sweep axis and a plane. The guide track defines a first free end, a second free end and an apex between the first end and the second end along the sweep axis. The sweep axis defines a first tangent to the sweep axis at the first end, a second tangent at the second end, and a third tangent at the apex, wherein a first line drawn perpendicularly to the first tangent and a second line drawn perpendicularly to the third tangent form a first included angle in the plane of the guide track that ranges from 10 to 45 degrees.

An umbrella with an adjustable canopy comprises a canopy adjustment device having a transverse rod connector, an upper clutch gear, a lower clutch gear and a handle; and a transverse rod rotation device disposed on the middle of a transverse rod; the front end of a tilted rod is rotatably connected to the transverse rod rotation device; the bottom end of the transverse rod is rotatably connected to a sliding block through the canopy adjustment device. The upper clutch gear is fixedly connected to the transverse rod; the bottom end of the transverse rod connector is rotatably connected to the sliding block; one end of the handle is rotatably connected to the periphery the upper clutch gear which is against the upper surface of the lower clutch gear. The invention has the advantages of simple and reasonable structure, convenient operation, stable and reliable positioning, and can realize the canopy adjustment only by operating the handle.

A physically-impaired-assisting multi-function sail comprises: a stanchion, a hoisting navigator for allowing an arthritic to deploy and retract the sail without the need to bend the fingers, a hoisting teeter totter secured to the navigator, a teeter-totter hook-lock secured to the teeter totter for automatically locking and unlocking the teeter totter to deploy and retract the sail, a cable secured to a camber, a cable canal formed into the teeter totter for hiding and protecting the cable within, a pivoting pulley housing secured to the teeter totter, a pivoting pulley hub swingingly attached to the pivoting pulley housing, sail-buttresses hingedly attached to the pivoting pulley hub, a sail canopy secured to the sail-buttresses, multiple cable pulleys rotatably secured at multiple locations within the pivoting pulley housing and pivoting pulley hub, a central tube attached to the pivoting pulley hub, sail-buttress-supporting arms hingedly attached to the sail-buttresses, and a shuttling hub attached to the sail-buttress-supporting arms.

A novel umbrella is disclosed with a simplified structure that creates a clean, elegant profile with reduced component count and increased wind resistance. The umbrella includes a support post, a housing supported thereby, spokes pivotally disposed about the housing, a canopy, and an actuator. The housing has a top hub and a bottom hub. The actuator slides the hubs together to pivot the spokes away from the housing, whereby the umbrella moves from a closed position to an open position. Rollers are preferably retained within the top hub, and each spoke preferably has a spoke cam attached to one end. The spokes pivot away from the housing by having a roller surface of each spoke cam slide along each respective roller. The actuator may have a crank operated worm drive mechanism to raise and lower the canopy.

A cantilevered umbrella, comprises a stand column, an umbrella tent and a cantilever. One end of the cantilever is connected with the stand column through a shell in a rotating mode, and other end is connected with the umbrella tent. Rotation of the cantilever drives the umbrella tent to rotate, with opening of the umbrella tent rotating to a certain angle in a relatively horizontal direction. The cantilevered umbrella further comprises a positioning part. One end of the positioning part is connected with the cantilever in a fixed mode, and other end extends into the shell. A first positioning portion is arranged on an inner wall of the shell, a second positioning portion is arranged on the positioning part, and the first and second positioning portions limit the cantilever in the circumferential rotating range through coordination.

The present invention provides a conveniently open and close sun umbrella, which includes a vertical pole, a connecting rod, an inclined rod, an umbrella frame and an umbrella opening mechanism. The two ends of the connecting rod are respectively hinged on the vertical pole and the inclined rod. The umbrella opening mechanism includes a first pull rope, a movable pulley, a second pull rope and a slide locking piece which is slidably mounted on the vertical pole. One end of the inclined rod is hinged on the slide locking piece, and the other end is hinged on a fixed umbrella disk. One end of the first pull rope is fixed on the movable pulley, and the other end is fixed on the movable umbrella disk. One end of the second pull rope is fixed on the vertical pole, and the other end is fixed on the slide locking piece.

A cantilever umbrella has an upstanding mast and a cantilever arm adapted to support a canopy. The cantilever arm is pivotally attached to the mast at an upper portion and configured to pivot between an open position where the canopy is deployed and where the cantilever arm extends away from the mast, and a closed position where the canopy is withdrawn and the cantilever arm extends close to the mast. The mast has interior region defined by a longitudinally extending channel with a longitudinally aligned opening extending from the interior to the exterior of the mast. A carriage resides within the channel and is adapted for travel within the channel. A support arm pivotally connected with the cantilever arm at one end, and pivotally connect with the carriage, through the channel opening at an opposing end. Raising of the carriage within the channel causes the cantilever to transition to the open position, and lowering of the carriage causes the cantilever to transition to the closed position.

The umbrella includes a support post, a housing supported thereby, spokes pivotally disposed about the housing, a canopy, and an actuator. The housing has a top hub and a bottom hub. The actuator slides the hubs together to pivot the spokes away from the housing, whereby the umbrella moves from a closed position to an open position. Rollers are preferably retained within the top hub, and each spoke preferably has a spoke cam attached to one end. The spokes pivot away from the housing by having a roller surface of each spoke cam slide along each respective roller. The actuator may have a crank operated worm drive mechanism to raise and lower the canopy. In particular, the umbrella may include a threaded rod coupled to a crank for screwing into a receptacle in the housing for moving the hubs closer together, causing the spokes to pivot away from the housing, whereby the umbrella moves from a closed position to an open position.
