A collapsible ground sheet has a floor made of a sheet of flexible, waterproof or water-resistant material, and walls attached to the floor and extending from the floor in a top direction. The walls are arranged about the periphery of the floor in series in a ring formation such that each of the walls has two neighboring walls. Each wall has a fabric portion and a wire loop, the wire loop disposed near the periphery of the fabric portion such that the fabric portion is supported by the wire loop. Each of the walls attached to its two neighboring walls by hourglass-shaped gussets made of a sheet of flexible material.

A weighted-corner towel apparatus for maintaining position of a towel includes a towel body having a body top side, a body bottom side, and a rectangular body perimeter including four corners. A plurality of weight pockets is coupled to the towel body. Each weight pocket is coupled to the body bottom side adjacent one of the corners of the body perimeter. A plurality of weight beads is coupled within the plurality of weight pockets. The towel body and each of the plurality of weight pockets is a heat and water-resistant material.

A folding ground cover assembly that can automatically pop open when released. The ground cover assembly has a fabric panel that is selectively supported by a detachable support mesh. The support mesh has a peripheral band that surrounds an open central area. Various cross straps extend across the open central area between points along the peripheral band. A spring wire engages the peripheral band of the support mesh and biases the peripheral band into an open, flat configuration. A first plurality of fasteners is disposed on the support mesh that engages a second plurality of fasteners on the underside of the fabric panel. The fasteners are used to connect the fabric panel to the support mesh, wherein the fabric panel covers the open central area and the fabric panel is supported by the cross straps.

A foldable beach chair mat includes two chair support pads, each comprising a respective rigid planar body. An elongated edge of the first rigid planar body has a first semicircular aperture comprising a first concave end face, and a corresponding elongated edge of the second rigid planar body has a second semicircular aperture comprising a second concave end face. An elongated hinge is positioned between and pivotally connects the elongated edges, to pivot and fold the first rigid planar body towards the second rigid planar body to a face-to-face abutment, to fold the mat. In an extended position, the first rigid planar body and the second rigid planar body are coplanar. The mat includes a carry strap for carrying the mat in a folded state and also has a retention strap for maintaining the folded state. A plurality of cupholders are defined by the rigid planar bodies for accommodating beverage containers.

New forms of towels, mats, tarps and other ground-covering sheets, and other devices, systems and methods providing protection from sand, dust, debris, and fluids are provided. In some aspects of the invention, ground covering sheets with an inherent guard, partially around a periphery of the sheets, are provided. In several embodiments, specialized ground-covering sheets are provided with reinforced, specialized sections configured to receive and hold legs, ground stakes and/or other parts related to structures to be mounted in, on or about such ground-covering sheets. In some such embodiments, such reinforced, specialized sections include a matrix of expandable receiving brackets, through which the support legs, ground stakes and/or other parts can penetrate, and reach and obtain direct support from the ground below such ground-covering sheets.

In one embodiment there is provided a clip for use with a yoga mat and towel. The clip includes a first and second plates each having a first and second jaw section, respectively. The jaw sections are disposed to face each other. The clip further includes a threaded knob configured to move the first and second plate such that the first jaw section and the second jaw section move into and out of open and closed configurations. The threaded knob is configured to fit within a well defined on the first plate and an opening defined on the second plate, such that a height profile of the threaded knob matches a height profile of the first and second plates when assembled.

A weighted covering assembly including a flexible cover configured with channels adapted to receive and hold weighted members is provided. The covering assembly may be used a ground covering (e.g., as a beach towel, picnic blanket, etc.) upon which one or more persons may sit or lay. The channels and associated weighted members may be configured along one or more sides of the covering to add weight to the covering and to prevent the covering from being shifted or otherwise moved by external forces such as wind, users of the covering, or other forces. The weighted members also may include padding to be used as a pillow.

A beach blanket including a stretchable main panel having two opposite sides comprising a body supporting top side for individuals to sunbath on and a bottom side for resting on a sandy beach surface, and a plurality of invertible bags attached to perimeter of the stretchable main panel. Each bag pivots about the stretchable main panel to allow users to scoop a large quantity of sand within each bag. The sand-filled bags are positioned on the beach to provide opposing tension on the main panel to easily eject sand off the blanket, and to securely anchor the beach blanket onto a beach which also prevents wind from blowing the beach blanket away.
