Weight systems and methods stabilizing objects

A weight system for containing fill material for supporting a free-standing object, comprising:

• a container defining an interior chamber adapted to contain the fill material, where the container comprises
• an outer side wall made of flexible fabric,
• a lower wall made of flexible fabric,
• an upper wall made of flexible fabric, where the upper wall is configured such that displacement of at least a portion of the upper wall defines a fill opening,
• an inner side wall made of flexible fabric;
• a first lower seam that joins the lower panel to the inner side panel, where the second lower seam is continuous around a lower outer edge of the lower wall,
• a second lower seam that joins the lower panel to the inner side panel, where the second lower seam is continuous around a lower inner edge of the lower wall,
• a first upper seam that joins the at least one upper wall panel to the at least one outer side panel, where the first upper seam is continuous around at least a portion of an upper outer edge of the upper wall, and
• a second upper seam that joins the at least one upper wall panel to inner side panel, where the second upper seam is continuous around at least a portion of an upper inner edge of the upper wall;
• and
• a closure system comprising first and second closure portions, where
• the first closure portion is arranged to define a first side of the fill opening, and
• the second closure portion is arranged to define a second side of the fill opening;
• wherein
• the closure system is arranged to allow the container to be configured in
• a closed configuration in which the first closure portion engages the second closure portion substantially to prevent access to the interior chamber through the fill opening, and
• an open configuration in which the first closure portion is disengaged from the second closure portion to allow access to the interior chamber through the fill opening;
• when the flexible fabric defining the upper wall is substantially planar, the fill opening and the closure system defined by the first and second closure portions are substantially within a plane defined by the upper wall;
• and
• the upper wall is displaced relative to the side wall to reconfigure the container between the open configuration and the closed configuration in a direction away from fill material within the interior chamber of the container.

A weight system for containing fill material to support a free-standing object, comprising:

• at least one flexible side wall;
• a flexible lower wall;
• a flexible upper wall;
• and
• a closure system comprising first and second closure portions;
• herein
• the upper wall, the at least one side wall, and the lower wall are joined to form a container defining an interior chamber and a fill opening;
• the closure system is arranged to allow the container to be configured in
• a closed configuration in which the first closure portion is arranged on a first side of the fill opening, the second closure portion is arranged on a second side of the fill opening, and the first closure portion engages the second closure portion substantially to prevent access to the interior chamber through the fill opening, and
• an open configuration in which the first closure portion is disengaged from the second closure portion to allow access to the interior chamber through the fill opening;
• and
• the closure system is supported at least in part by the upper wall such that fill material within the interior chamber engages the at least one side wall and does not engage the closure system.
