Abstract: A collapsible apparatus is provided that includes a frame configured to form a closed loop, the frame being moveable between a coiled configuration and an uncoiled configuration. A sleeve is configured to receive the frame and to define an opening within at least a portion of the closed loop. An attachment mechanism is coupled substantially about the periphery of the sleeve. A fabric member is removably coupled to the sleeve such that it is easily removed. A method of making mats according to an embodiment of the invention includes cutting fabric members from a first sheet of material, cutting body membranes from a second sheet of material such that the amount of excess material from the second sheet of material between adjacent body membranes is minimized, and attaching one of the body membranes to one of the fabric members.

Abstract: A valve is provided that includes a body portion defining a conduit and a control element coupled to the body portion and configured to selectively engage the body portion adjacent the conduit. The control element is configured to be axially repositioned based on axial movement of the body portion.

Abstract: A collapsible flotation device is provided that uses a coilable spring coupled to a panel to collapse the device when the spring is coiled, and to expand the device when the spring is uncoiled configuration. The spring can be contained within a sleeve along the outer portion of the panel. A support member that traverses the panel is provided. An inflatable bladder disposed about a part of the outer portion of the panel and coupled to the support member buoyantly supports a body weight of a user. The combination of the inflatable bladder and the support member provide support for a user in a seated position on the panel. Many configurations are disclosed, including a multi-user collapsible flotation device, multiple connected single-user flotation devices, and so forth. A back support member and a headrest, both of which can be inflatable, provide additional support for a user to maintain a seated position on the panel. A foot support member is provided for the comfort of the user.

Abstract: An apparatus or support having a frame that can be disposed in an expanded configuration and a collapsed configuration. The frame includes a first end portion, a second end portion, a first side portion, a second side portion, and several connectors. Each of the connectors are disposable at a first position when the frame is in its expanded configuration and are disposable at a second position when the frame is in its collapsed configuration.

Abstract: A shade includes a frame member being formed from a flexible twistable material and a membrane. The shade includes a strap coupled to two ends of the membrane.

Abstract: A support including a frame having a tension member coupled to the frame is disclosed. The frame has a collapsed configuration and an expanded configuration. The tension member is disposable in a first position to provide support for an arm of a user and a second position to be carried on a shoulder of the user.
