A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

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 beverage holding support structure, for use in a pool, includes a base configured to be disposed at a non-equilibrium sloped position within a pool relative to a horizontal plane and parallel to a sloped bottom surface of the pool, a base connector connected to the base, an articulating mechanism adjustably coupled to the base connector and extended upwardly therefrom, at least one extension pole aligned with a centrally registered longitudinal axis and statically affixed to an upper portion of the articulating mechanism, and a cup holder tray attached to the at least one extension pole. The beverage holding support structure has a center of gravity configured to prohibit the base from being tipped over from the non-equilibrium sloped position while the cup holder tray is maintained at a horizontal position parallel to the horizontal plane above a top water level surface of the pool.

An anchor for supporting an elongate tubular object, the anchor including an elongate tubular member having a proximal end and a distal end; a nozzle at said proximal end, the nozzle having an opening remote from said elongate tubular member; and, a funnel at the distal end, the funnel tapering from a minimum diameter at the tubular member to a maximum diameter remote from the tubular member; wherein the funnel, the elongate member, and the nozzle are in liquid communication. The anchor may further include at least one fin extending outwardly from the tubular member, a fixation device for securing an elongate tubular object inserted through the funnel and into the tubular member, and/or a collar having an outside diameter greater than that of an outside diameter of the elongate tubular member.

A rib assembly for an outdoor umbrella is capable of being telescopically packed. The rib assembly includes a longer rib and a shorter rib. When the rib assembly needs to be disassembled for packing, the longer rib or/and the shorter rib is able to be superimposed and retracted along a length direction. A locking mechanism is disposed on the longer rib or/and the shorter rib. When the rib assembly needs to be extended completely, the longer rib or/and the shorter rib are locked by the locking mechanism.

An outdoor umbrella frame has a telescopic structure, and includes an umbrella pole, a pull rod assembly and a rib assembly. The pull rod assembly includes a first pull rod and a second pull rod. The rib assembly includes a longer rib and a shorter rib, the umbrella pole may be telescopic along a length direction, and one or more of the first pull rod, the second pull rod, the longer rib and the shorter rib may be telescopic along a length direction. When the outdoor umbrella frame is assembled, the umbrella pole, the first pull rod, the second pull rod, the longer rib and the shorter rib are all in an extended and fixed state. When the outdoor umbrella frame is disassembled for packing, any one or more of the umbrella pole, the first pull rod, the second pull rod, the longer rib and the shorter rib are in a retracted state.

A rapid assembly structure includes an upright post, wherein the upright post includes a first upright post and a second upright post; the rapid assembly structure further includes a sleeve assembly, wherein the sleeve assembly includes a first sleeve base and a second sleeve base, the first sleeve base is configured to install the first upright post in a fitting manner, the second sleeve base is configured to install the second upright post in a fitting manner and the first upright post is connected to the second upright post by the fit of the first sleeve base and the second sleeve base; after the first sleeve base is in docking fit with the second sleeve base, a partial side wall in the first sleeve base extends outwards and is in close fit with an inner cavity wall of the first upright post.

Cooling systems are provided. The cooling systems include a plurality of cooling units. Each cooling unit has a base having a housing with control components, a cooling tower attached to the base at a first end of the cooling tower, with an inner flow path and an exterior surface, and an air distribution system attached to the cooling tower at a second end. The air distribution system includes an air distribution chamber between first and second enclosures, cool and warm air dispensers are configured in the first enclosure, and a cover is disposed on an exterior of the enclosures. The control components are configured to convey air through the base, the cooling tower, and the air distribution system to dispense air through the air dispensers. At least two of the cooling units of the plurality of cooling units are arranged in a linear arrangement.
