A liquid containment vessel or pool having a wall constructed of thermoplastic polymers. Most pool walls are manufactured from steel or aluminum which are prone to deformation and corrosion. Polymer sheets or banding can be used to replace customary pool walls, offering a tough, strong, lightweight, corrosion resistant and easily installed material that can be manufactured from recycled plastics. When oriented, laminated, woven, corrugated, or layered, the strength of the polymer sheeting or banding increases further, allowing the present invention to be adapted for use in a variety of applications.

A pool apparatus configured to carry liquids has a side wall and a bottom surface. The side wall has a plurality of structure drawstrings, an outer side wall, and an inner side wall. Two sides of the structure drawstrings draw respectively the outer side wall and the inner side wall, so as to maintain a predetermined shape of the pool apparatus. The structure drawstrings include a main drawstring portions and at least two branch drawstring portions. The main drawstring portions have a first main string side configured to connect a first branch drawstring side of the at least two branch drawstrings. A second branch string side of the at least two branch drawstrings connects respectively to different positions of the outer side wall and the inner side wall.

A pool unit including a pool shell, which has a wall, and a bracing structure bracing the wall to curve inwardly. The pool shell is fillable with water to straighten the wall to form a straight wall.

Insulated portable spas and processes for insulating spas are described herein. The processes can include filling the undercabinet cavity of the spa with insulative fiberglass while the spa is in an upright position. The insulative fiberglass can be blown-in through sidewalls of the box frame. The portable spas can include an insulative air barrier at the bottom of the spa.

A combination of a first separate and independent pool component and a second separate and independent pool component includes a first frame portion having a frame support component for the first pool component, and a second frame portion having a frame support component for the second pool component. The second frame portion is complementary with the first frame portion. A latch assembly has a first latch component and a second latch component. The first latch component is adapted to be removably coupled to the second latch component. The first latch component of the latch assembly is attached to the frame support component of the first frame portion of the first pool component, and the second latch component of the latch assembly is attached to the frame support component of the second frame portion of the second pool component. The first pool component and the second pool component are placed so that their complementary frame portions and the cooperating first and second latch components are aligned, and the first latch component of the latch assembly is operatively attached to the second latch component with which it is aligned.

The invention relates to a speed reducer (10) with two intermediate transmission lines (16), in particular for a turbine engine, including an input line (12) and an output line (14) driven by the input line via said intermediate lines, said intermediate lines being substantially parallel, characterised in that it includes load-distribution means between said intermediate lines, said load-distribution means comprising ball-and-socket means (30) for rotatably coupling a first end of the input line, first means (34) for damping the radial movements of said end of the input line, and second means (34) for damping the radial movements of a second opposite end of the input line.

The present invention provides a above ground pool, comprising a flexible pool body. The flexible pool body comprises: a polygonal bottom sheet that comprises a plurality of edge portions; and a plurality of side sheets, each side sheet comprising a pool sidewall portion and a pool bottom portion, and each of the pool sidewall portions and each of the pool bottom portions being in the shape of an isosceles trapezoid. Each of pool sidewall portion comprises a first upper-base portion, a first lower-base portion and a first middle portion defined between the first upper-base portion and the first lower-base portion, and each of the pool bottom portion comprises a second upper-base portion, a second lower-base portion and a second middle portion defined between the second upper-base portion and the second lower-base portion. The first lower-base portion and the second lower-base portion coincide to define a junction of the pool sidewall portion and pool bottom portion. The first middle portions of the side sheets are successively connected to form a side wall of the above ground pool and the second middle portions are successively connected to form an outer ring of the bottom of the above ground pool. The second upper-base portions of the pool bottom portions are respectively connected to the edge portions of the bottom sheet. In the above ground pool of the present invention, joints are moved to a side wall of the swimming pool or the bottom of the swimming pool as much as possible, thereby reducing the length of joints passing through a heavily stressed area to the greatest extent, simplifying production processes, reducing costs, and reducing the probability of water leakage from the above ground pool.

The structure drawstrings include a main drawstring portions and at least two branch drawstring portions. The main drawstring portions have a first main string side configured to connect a first branch drawstring side of the at least two branch drawstrings. A second branch string side of the at least two branch drawstrings connects respectively to different positions of the outer side wall and the inner side wall.

The present disclosure provides an inflatable pool and a method for forming an inflatable pool. A pool body includes: an annular body and a bottom wall connected with the annular body, wherein the annular body is configured with a first air chamber, and a pool boundary is disposed on the annular body and the bottom wall; a pair of bases disposed on an end portion of the annular body opposite to the bottom wall and being spaced along a circumferential direction of the annular body; and an elastic component disposed between the pair of bases along the circumferential direction of the annular body to form a shooting device. Accordingly, the present disclosure provides an inflatable pool with a new profile.
