A foldable lap table assembly for creating storable and adjustable height table surfaces includes a top table and a pair of top legs hinged to the top table and a bottom table with a pair of bottom legs hinged to the bottom table. A storage configuration is defined by the bottom table with the pair of bottom legs in a bottom folded position receiving the top table with the pair of top legs in a top folded position to form a rectangular prism. An alternate box configuration is defined by the pair of top legs in an alternate top extended position engaging a bottom upper face of the bottom table to form a rectangular prism with an open front and an open back.

A post-mounted tray assembly for mounting to a post, pole, or other vertical support structure includes a first portion defining a first plate and a first mounting bracket, and a second portion defining a second plate and a second mounting bracket. A clamping mechanism including one or more mechanical fasteners may be used for joining the first mounting bracket and the second mounting bracket around the post, such that the post passes through a central aperture defined between the first portion and the second portion.

A foldable chair side table has a snap-on/snap-off clamp which is designed for easy and simple installation on most foldable chairs. A leveling system is provided for ready adjustment to horizontally align the table in relation to the chair. The table is lightweight for ease of use and portability and comes equipped with an attached strap. It has a variety of unique features not found in prior side tables, including a solar powered charger having charging panels for electrically charging cell phones, tablets, and other electronic devices. The table also comes equipped with dual USB ports having a protective cover, a cup holder, a storage compartment, and rotatable leg members to allow placement of the side table on the ground, a table, or other flat surface.

A foldable tray includes first and second base sections (BSs), lateral side members (LSMs) and a locking device. Each BS comprises opposed lateral edges, an inboard edge and a rigid hard surface. They are adjacent along their inboard edges, and foldable along those edges between an extended position where the hard surfaces lay in a plane and a folded position where the surfaces are stacked. The LSMs are attached along the opposed lateral edges of each of the BSs and foldable along that attached edge between an upright position where the LSM is at a substantial angle to the hard surface of its attached BS and a portable position where it is either stacked with its attached BS or has a major surface lying in the same plane as the hard surface of its attached BS. The locking device retains the BSs in the extended position only when engaged.

Modular tray systems and methods of using the modular tray systems to support a variety of items either in a free-standing orientation or by securing the modular tray system to a chair. Such a modular tray system includes a tray and one or more features for supporting the tray with or from the supporting structure. The tray has a tray member, a base member connected to the tray member, an upper surface, a lower surface, and first and second connecting features defined in, respectively, the tray member and the base member at the lower surface of the tray. The supporting features include at least one of a support rod and a support throne that have third connecting features that are complementary to each of the first and second connecting features of the tray.

A desk platform structure for a fitness bike, including a desk platform, a desk platform fixing and sliding mechanism and a supporting rod is provided. The desk platform fixing and sliding mechanism includes a pair of fixing bars, a pair of sliding rails, and a fixing rack. The desk platform is installed on the fixing bars which are installed on the sliding rails. The sliding rails are fixed on guiding bars at two sides of the fixing rack which is connected to the supporting rod. A braking mechanism and a control mechanism for sliding and positioning of the fixing bar are disposed between the fixing bar and the fixing rack. Accordingly, the desk platform is more stable and reliable, and may slide and be positioned at any location. It is convenient to use the desk platform by further adjusting the inclination angle of the desk platform.

A tray capable of being frictionally engaged to a support structure comprises a horizontally oriented planar base having an edge. A right-angle bracket has a horizontally oriented side. An edge of the horizontally oriented side of the right-angle bracket is coupled adjacent the edge of the base and extends in a direction parallel to a plane of the base. The right-angle bracket has a vertically oriented side coupled to the horizontally oriented side at a corner of the right-angle bracket and extending downward. A bracket is coupled to a bottom surface of the base and extends downward in the direction substantially normal to the base. This bracket is positioned opposite the right-angle bracket a horizontal distance sufficient to receive the support structure positioned therebetween. A screw comprising a handle at a first end of the screw and a shoe at a second end of the screw passes through a threaded hole in the bracket and extends toward the right-angle bracket. Moving the handle causes the shoe and the right-angle bracket to frictionally engage the support structure positioned therebetween.

A desk platform structure for a fitness bike, including a desk platform, a desk platform fixing and sliding mechanism and a supporting rod is provided. The desk platform fixing and sliding mechanism includes a pair of fixing bars, a pair of sliding rails, and a fixing rack. The desk platform is installed on the fixing bars which are installed on the sliding rails. The sliding rails are fixed on guiding bars at two sides of the fixing rack which is connected to the supporting rod. A braking mechanism and a control mechanism for sliding and positioning of the fixing bar are disposed between the fixing bar and the fixing rack. Accordingly, the desk platform is more stable and reliable, and may slide and be positioned at any location. It is convenient to use the desk platform by further adjusting the inclination angle of the desk platform.

In an illustrative embodiment, a two-piece folding tray table includes a personal electronic device (PED) support member connected to a tray section such that, in a stowed position, the PED support member is substantially flush with the tray table. The PED support member may be deployable in both a folded tray table configuration and a side-by-side tray table configuration to support a personal electronic device at a substantially identical angle regardless of tray table use mode.

A detachable, multifunctional rack for electronic devices includes a rectangular platform (1) including a lower board (10) secured to an underside, two sets of a plurality of hollow members (11) on two sides of the lower board (10) respectively, and a space (15) under the lower board (10); two L-shaped supports (2) mounted to two sides of the platform (1) respectively, each support (2) including a horizontal member (21) releasably secured to either side of the platform (1), a vertical member (22) releasably secured to the horizontal member (21), and a plurality of aligned, spaced tubular members (23) on one side of the horizontal member (21); and two pins (14) each passing through one set of the hollow members (11) and the tubular members (23) at either side of the platform (1) to fasten the platform (1) and the supports (2) together.
