A table includes a table top with an upper surface and a lower surface. The table top is preferably constructed from blow-molded plastic and it includes a generally hollow interior. The table top includes a downwardly extending lip one or more strengthening members that are integrally formed in the lip. The lip is desirably integrally formed in the table top as part of a unitary structure and the lip includes a generally hollow interior that is integrally formed during the blow-molding process with the generally hollow interior of the table top. Advantageously, the table top may include a plurality of depressions that are integrally formed in the table top and the strengthening members may be generally aligned with at least some of the depressions. The strengthening members include one or more of inwardly extending portions, outwardly extending portions and / or ribs that increase a thickness of the lip. The strengthening members may also be formed in a corner of the table top.

A headphone is made handy for carrying or storing. The headphone includes a pair of right and left headphone units, and an elastic band formed substantially into a U shape, which is mounted ranging from the human head to both sides of the head, and supports the headphone units in end portions thereof. A multiaxial arm joint is provided between an end part of the elastic band and the headphone unit, and includes a first arm, one end of which is connected turnably to the end part of the elastic band, and a second arm, one end of which is connected turnably to the other end of the first arm and the other end of which is connected turnably to the headphone unit. By turning the connecting portions of the multiaxial arm joint, the headphone units are housed within an internal space encircled by the elastic band.

Collapsible indoor and outdoor containers having a collapsible wall section with shape-retaining characteristics are disclosed. In particular, collapsible coolers, fish bins, and wheeled vertical bins are provided. The collapsible wall section may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively stiff or rigid material. The coolers, fish bins, and wheeled vertical bins are each advantageously provided with a collapsible insert container that nests within and collapses together with a shell of the respective container, the respective wall folds of the shell and insert meshing together to result in a combined collapsed vertical dimension as small or nearly as small as that of the collapsed shell alone.

A table includes a table top, a frame, and a pair of non-circular openings are formed in the frame. The table also includes a leg that is movable between an extended position and a collapsed position relative to the table top. A connecting rod connects the leg to the pair of openings in the frame and the connecting rod preferably has a non-circular cross-sectional configuration. The connecting rod and the openings in the frame are sized and configured to loosely attach the leg to the table when the leg is in the collapsed position. The connecting rod and the openings, however, are sized and configured to securely attach the leg to the table when the leg is in the extended position.

A foldable member including a first structural section foldable flat and biased to have an open configuration and a second structural section also foldable flat and biased to have an open configuration. The second section is longitudinally aligned with the first structural section when both structural sections are in the open configuration. A hinged connection between the first and second structural sections allows the first structural section to be folded against the second structural section when both structural sections are folded flat.

A folding chair may include an upper frame, two armrests, two side frames, a front linking unit and a rear linking unit. When the user moves the armrests down to start chair folding process, the front linking unit and rear linking unit start to shrink and bring the side frames closer to each other. In the mean time, two side connecting rods are driven to bring the upper frame to moves down and further squeeze a seat fabric into a space between two side frames to form a compact structure of the folding chair. The size of the folding chair can be determined by extended length of the front linking unit and a rear linking unit. The folding chair proposed in the present invention is comfortable and stable for the user to sit, and all elements of the folding chair can be easily and closely folded into a compact size.

According to various illustrative embodiments of the present invention, a device for a light projection system includes a single light emitting diode array comprising at least one green die, at least one blue die, and at least one red die, a single light collection, integration, and etendue-matching optic element comprising a tapered light pipe capable of collecting substantially all light emitted by the single light emitting diode array and spatially integrating the substantially all the light emitted by the single light emitting diode array, and a telecentric relay using at least one of spherical and aspherical refractive and reflective components. The device also includes an illumination wedge prism, a digital micromirror device capable of modulating the substantially all the light emitted by the single light emitting diode array, and a projection total internal reflection prism, the projection total internal reflection prism disposed between the illumination wedge prism and the digital micromirror device. The device also includes a projection lens, wherein the telecentric relay provides the substantially all the light emitted by the single light emitting diode array through the illumination wedge prism and through the projection total internal reflection prism to the digital micromirror device that reflects the substantially all the light emitted by the single light emitting diode array back through the projection total internal reflection prism that totally internally reflects the substantially all the light emitted by the single light emitting diode array through the projection lens.

A foldable stool or table having hinges comprises a plurality of support members. In one embodiment, a foldable device comprises three legs. In another embodiment, the foldable stool or table comprises two foldable support members and two non-foldable support members. Relative to the top and bottom of the device, embodiments of the present invention may comprise one or more intermediately located steps or shelves, wherein the steps or shelves are located along at least one of the non-foldable support members. The one or more intermediately located steps or shelves may be forwardly-offset relative to a front surface of the non-foldable support members. A method of using the stool is also provided.
