The invention discloses a process to implement and maintain water bodies larger than 15,000 m3 for recreational use, such as lakes or artificial lagoons, with excellent color, transparency and cleanness properties at low cost, which comprises the following steps:a.—providing a structure able to contain a large water body larger than 15,000 m3;b.—feeding the structure of step (a) with inlet water having iron and manganese levels lower than 1.5 ppm and turbidity lower than 5 NTU;c.—measuring water pH, ideally it should be within a range lower than 7.8;d.—adding an oxidizing agent to the water contained in the structure of step (a), with which a 600 mV minimal ORP is controlled in water for a minimal period of 4 hours and in maximal cycles of 48 hours;e.—adding a flocculating agent in concentrations within 0.02 and 1 ppm with maximal frequencies of 6 days and cleaning the bottom of the structure of step (a) with a suction device to remove precipitated impurities from the bottom of said structure, together with the additional flocculants and;f.—generating a displacement of surface water containing impurities and surface oils by means of the injection of inlet water according to step (b), which generates said displacement in such a way to remove said surface water by means of a system for impurities and surface oils removal arranged in the structure of step (a), which together with step (e) replaces traditional filtering.The present invention also discloses a structure to contain large water bodies comprising a system for the removal of impurities and surface oils by means of skimmers and the suction device to clean said structure.

An expandable and collapsible table for use with a miter saw or for recreational use. A support structure includes a truss that is expandable and collapsible in the horizontal direction. A pair of expansion leaves are pivotally connected to opposing sides of the support structure. A support arm and extension arm work in combination with a locking mechanism to maintain the expansion leaves in the horizontal position or alternatively to allow the expansion leaves to collapse to a vertical position.

A vehicle that is a motor home having a slide out body member that extends across an opening in the side wall of the vehicle body is disclosed. The slide out body member is capable of movement between a laterally expanded position during recreational use of the vehicle and a refracted position for travel of the vehicle on roads. The slide out body member has a primary wall portion covering at least a portion of the side wall of the vehicle body and end walls at each end of the primary wall portion extending back towards the vehicle body. The slide out body member also has a top and a bottom extending from the upper and lower edges of the primary wall portion back towards the vehicle body so that the space defined by the slide out body member opens into and forms part of the interior space of the vehicle body. The vehicle also includes a service connector in the form of a flexible conduit extending between the vehicle body and the associated service fittings in the vehicle slide out. It also includes a conduit organizer for guiding the flexible conduit to fold up and then unfold when the slide out body member is moved between the expanded and refracted positions.

An aerodynamic device includes a plate having a generally circular periphery, a central portion, and a plurality of compartments for holding food substances during a dining activity. Each compartment is bounded by curved ribs, each rib extending continuously from the central portion along an arcuate path to the periphery. All of the ribs are aerodynamically shaped to provide lift during a subsequent recreational activity in which the device is thrown through the air. An insert is mounted in the central portion for holding a dining item, e.g., a drink container, for use during the dining activity, and a different recreational item for use during the recreational activity.

The invention provides a child seat and a using method thereof, and belongs to the technical field of furniture. The problem that an existing child seat cannot meet different dining environment requirements is solved. The child seat comprises a child seat bag and a plurality of chair legs. The child seat bag is provided with a plurality of chair leg connecting portions; the chair legs and the chair leg connecting portions are connected through detachable connecting structures; the bottom of the child seat bag is provided with an annular supporting ring or a plurality of supporting feet, and the bottom face of the supporting ring or the bottom faces of the supporting feet are located below the bottom faces of the chair leg connecting portions. The child seat comprises the matched using method, an independent using method of the child seat bag and an entertainment using method, then, the child seat can be normally used in different dining environments, and comfort and safety can be ensured.

A mobile, collapsible table and storage assembly for outdoor recreational use. The assembly includes: a storage compartment having a receptacle and lid, wheels at a first end of the storage compartment, a stand connected to the first end, a handle connected to the storage compartment at a second end, and folding legs connecting the receptacle and lid of the storage compartment. Each leg has a lower limb and an upper limb connected by a pivot, such that the limbs are movable between a folded and unfolded position. An end of one of the limbs at which the pivot is located has an extension portion which engages an adjacent end of the other limb to allow the lower and upper limbs to assume the unfolded position when forming an angle greater than 180 degrees. This prevents the table collapsing by buckling of the folding legs.
