Abstract: The electric display apparatus with a lighting system, comprising: an electric display column, a support frame, a display shelf, some lamps, some plastic strips and coppers. The electric display column includes some grooves and grids. The plastic strips are installed in the grooves; the coppers are installed in the plastic strips, and they are connected to the power supply. The multiple rectangular hanging holes distributing along the longitudinal direction of the grids; the hanging arms are installed on both ends of the support frame. The middle part of the hanging arm is installed with the guide groove, which bottom installed the positioning bolt. The insulating plastic material movable plug is fixed in the hanging arms, the interior of the movable plug inlaid with the electric copper, which is installed in the guide groove of the hanging arm. The display shelf is fixed to the support frame by the screw connection.

Abstract: An illuminating device includes an aluminum extrusion profile fixed on a back panel of a showcase, and a lamp device. A face panel of the showcase is secured to an end of the aluminum extrusion profile away from the back panel. In the middle of the aluminum extrusion profile defines a sliding slot extending horizontally. The face panel defines an elongated slot corresponding to the sliding slot. The lamp device includes a lamp and a conductive head. A conductive structure is secured to the sliding slot for allowing the conductive head to be plugged therein and conduct the conductive head. The conductive head can slide along the sliding slot to be located at any desired position to illuminate objects on the showcase. A ratchet connecting mechanism is arranged on the sliding slot and configured to mount and remove the conductive head.

Abstract: A connector for an elongate member in frame structures such as seating, scaffolding and the like, in which an elongate member is removably secured to another member to extend therefrom in selected angular relation. The connector includes a lug on one member and extending therefrom and shaped to be received inside of a tubular end of a second member with the lug and a partition in the second member having facing surfaces at an angle to a line on which the second member extends from the first member with fastening means drawing the partition toward the lug to clamp the adjacent end of the second member to the first member, the tubular portion of the second member having an opening adjacent the fastening member for access thereto, the engagement of the second member with the lug and first member and the relation of the partition to the lug cooperating to orient and fix the second member relative to the first member.
