Described is a portable bed for outdoor use by a dog or other large pet which is movement-resistant when placed on a ferromagnetic surface such as a truck bed. The bed includes a durable removable outer cover suitable for exposure to inclement weather and an inner cushioning element received within the outer cover which may be a dog bed suitable for indoor use. At least a portion of the outer cover comprises a material producing a sufficiently strong magnetic field to impede or prevent the bed from shifting or otherwise moving on the ferromagnetic surface. This may prevent or at least measurably reduce shifting or other movement of the portable dog bed in a truck bed when the vehicle accelerates, breaks or turns. Alternatively, the portable bed may be configured for use as an insert in a dog crate with an optional top spill pad for convenient removal and cleaning.

At least one embodiment of the inventive technology may be a disassemblable platform system in a pickup truck cab, or other vehicle, such as, but not limited to, a SUV or van that (after installation), comprises: a plurality of panels (generally, 40, as installed) relatively positioned to form a flat, raised rigid platform 41 in a pickup truck cab and that is elevated above lower seat cushions, where such panels include two rear panels 1,2 (i.e., in the rear seat area), a driver area panel 3, a passenger area panel 6, and a console area panel 42 between said driver area panel and said passenger area panel. The system further includes horizontal supports 43 that underlie at least some of said panels, such horizontal supports including at least two right-left horizontal support bars 44 (i.e., a horizontal support bar that is installed in a right-left direction defined by the vehicle); and panel-attached horizontal supports 45, each of which is attached to a panel to which it is dedicated.

A folding bed is provided, which includes a bed sheet, a first lateral supporting rod connected to a first edge of the bed sheet and a second side supporting rod connected to a second edge of the bed sheet. The folding bed further includes a first L-shaped supporting rod having a first end articulated to the first side supporting rod, a second L-shaped support rod having a first end articulated to the second side supporting rod, a gear connected to a second end of the first L-shaped supporting rod, and a gear locking member connected to a second end of the second L-shaped supporting rod. The gear locking member is provided with teeth which are rotatable in only one direction with respect to teeth of the gear. The folding bed is has a small size after being folded, is convenient to assemble and is easy to fold.

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.

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 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.

An elastic mattress has a base layer, a plurality of elastic modules and a pad layer. The elastic modules are detachably arranged on a second surface of the base layer and are configured to directly contact the ground. The pad layer is arranged on a first surface of the base layer. Since the plurality of elastic modules are arranged on the second surface of the base layer and can directly contact the ground, the number of components of the elastic mattress is reduced and the structure simplified lowering the cost of the elastic mattress, while providing high comfort. Moreover, as the pad layer can be removed from the first surface of the base layer, the elastic mattress can be more easily moved and stored.
