A thermally insulating single or multipart multilayer covering jacket for covering a person, includes a body side and an outer side. The covering jacket contains a transfer layer, a blocking layer, and a storage layer arranged between the transfer layer and the blocking layer. The transfer layer is arranged so as to face the body side and is water-permeable in the direction of the storage layer and water-impermeable in the direction away from the storage layer. The blocking layer is arranged so as to face the outer side and is water-impermeable in the direction away from the storage layer, and the blocking layer forms an intermediate space for storing condensed water which is formed from the steam transferred into the storage layer through the transfer layer.

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.

An embodiment of a heating system for a camp includes at least one heat exchanger bed. Each heat exchanger bed includes a bed frame defining a chamber therein, a bedding assembly positioned on top of the bed frame, and a heat exchanger positioned in the chamber that is configured to transfer heat to or from the bedding assembly.

A portable readily assembled and dismantled bunk bed has flexible bed support members with integral flexible head and foot and vertically disposed members that disconnectably engaged and hold the flexible bed support to a horizontal frame member and provide end members that prevent a child from sliding through the frame members.

A diaper changing table assembly for elevating and supporting a user requiring a diaper change includes a frame, which comprises a plurality of linear elements. The linear elements are mutually pivotally attached so that the frame is reversibly positionable in a stowed configuration and a deployed configuration. In the stowed configuration, the linear elements are substantially parallel and proximally positioned. In the deployed configuration, the frame is substantially cuboid. A top panel, which is resiliently flexible, is attached to an upper limit of the frame. The top panel is substantially compacted and substantially planar with the frame in the stowed configuration and the deployed configuration, respectively. The frame is deployable upon a substantially horizontal surface so that the top panel is substantially horizontally positioned. The top panel thus can support a user who requires a diaper change.

A modular vehicle platform system includes a frame, topper, and carrying case. Components of the frame are disassembled and compactly fit into the carrying case along with the topper. The system provides a modular, adjustable vehicle-camping platform designed to enhance stability, storage, and versatility for SUVs, trucks, and vans. The carrying case features adjustable partitions to neatly organize and secure all components, ensuring convenient portability. The frame consists of multiple support bars, poles, angle brackets, and interchangeable legs that can be adjusted to fit different vehicle configurations. Short legs and extendable legs can be swapped to modify the height of the platform, allowing for customized use in a variety of settings. The topper is constructed from slats connected by stretchable straps, providing a sturdy surface that can support a person. The system is easy to set up and dismantle, making it suitable for temporary or semi-permanent installations in different vehicles.

New forms of 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 integral vertical guard, provided around a periphery of such ground-covering sheets, are provided. In several embodiments, specialized ground-covering sheets are provided with reinforced, specialized sections configured to receive and hold tent legs and other rigid members parts of structures mounted in, on or about such ground-covering sheets. In some such embodiments, such reinforced, specialized sections include specialized reversible fasteners for interfacing with and holding feet of the tent legs. In other embodiments, the ground-covering sheets are configured to reversibly conjoin with auxiliary components, such as a fluid-holding basin provided below such a ground-covering sheet.

A frame structure defines a space capable of accommodating a user, and includes a plurality of outline frames that forms an assembly-type framework for the space, a sheet that is stretched over the framework so as to form a floor surface, a side surface, and a top surface of the space, a support frame that supports the floor surface at a position higher than a base surface where the frame structure is placed, a battery attachment portion that enables attachment of a battery to an under surface side of the floor surface, an outlet provided on any of the floor surface, the side surface, and the top surface, and a battery connecting portion that connects the battery attached to the battery attachment portion and the outlet.

A foldable base plate of an elastic mattress, the foldable base plate includes a plurality of mounting modules, the plurality of mounting modules and connecting modules are alternately spliced to form the foldable base plate, the plurality of mounting modules are disposed with tapered positioning members, the tapered positioning members are protruding cavity structures extending upward from the plurality of mounting modules, the plurality of mounting modules and the connecting modules are configured to be folded along a vertical direction to form a stacked structure, and when the foldable base plate forms the stacked structure: two adjacent ones of the plurality of mounting modules are connected by plugging through corresponding ones of the protruding cavity structures, and a corresponding one of the protruding cavity structures on a lower mounting module is inserted into a corresponding one of the protruding cavity structures on an upper mounting module.
