Abstract: A portable display device includes a display element provided with a main screen thereon, the portable display device further includes a secondary screen capable of being incorporated with the main screen. By providing a secondary screen, a display region of the portable display device can be extended as required, thereby allowing to run more applications to satisfy user's demands. And at the same time, the drawing structure can extend the display region in a convenient and steady manner.

Abstract: An exemplary display device includes a support member, a pair of displays slidably attached to the support member, and positioning members disposed between the displays and the support member. The support member includes a straight slideway, and a curved slideway defined therein. The curved slideway includes a slanting portion, and a first straight portion and a second straight portion extending out from opposite ends of the slanting portion. The straight slideway is parallel to the first straight portion of the curved slideway and in line with the second straight portion of the curved slideway. The displays are slidably received in the straight slideway and the curved slideway respectively. The displays may be positioned to form a large screen, or slid to overlap leaving a single display visible.

Abstract: A folding table and support frame assembly is disclosed. The table comprises two planar portions connected by a hinging member. One of the planar portions is coupled to a support frame such that the folded table can be moved into a stowed position within the support frame assembly. The planar portions comprise a proximal portion or inner member and a distal portion or outer member. The proximal portion and distal portion are connected to one another by the hinging member or middle member. The hinging member enables the rotation of the distal portion into a folded relationship upon the proximal portion. When the two planar portions are folded, they provide a smaller table surface in a half-open or partially extended position. When the two planar portions are opened along the hinging member, the planar portions and the hinging member provide a larger contiguous table in the fully extended position.

Abstract: A table extensible by turning over its side boards, constituted by a horizontal plane, having peripheral parts with upper side boards and lower side boards shaped as circle segments and a central part enclosed thereby. The central part is able to rotate on a base and is vertically movable relative thereto by means of cam profiles, which are fastened to the central part between the top surface of the lower side boards and of the upper side boards, which are fastened to the central part. The lower side boards are joined to a frame, bearing down on said base whilst the upper side boards are hinged to the upper side boards to be turned over outwardly.

Abstract: Folding table cabinet apparatus includes a base cabinet with a pair of folding doors secured to a base cabinet. Within the base cabinet is a table assembly. The table assembly is pivotally secured within the cabinet and is held therein by a pair of lock plates. The table assembly pivots outwardly from the cabinet and is supported by a pair of folding legs. The table includes two plates, a main table plate and an outer end extension or leaf plate which is pivotally secured to the main table plate. The extension or leaf plate is held in alignment with the main plate by a pair of slider elements which are pinned to the main table plate.
