|20120240337||TWO-STAGE ACTUATING DEVICE FOR ELECTRIC APPARATUS - A two-stage actuating device for an electric apparatus includes a driver mounted to a fixing frame of the electric apparatus and provided with a retractable rod, a link rod having one end pivotally connected with the retractable rod of the driver and the other end pivotally connected with a moveable frame of the electric apparatus, and a bracket having one end mounted to the moveable frame and the other end connected with the retractable rod in such a way that the link rod is pushed by the retractable rod within a first-stage stroke of the retable rod to drive a first-stage movement of the moveable frame, and then the bracket is pushed by the retractable rod in a second-stage stroke of the retractable rod to drive a second-stage movement of the moveable frame.||09-27-2012|
|20110271446||ELECTRIC FOLDABLE BED CAPABLE OF ADJUSTING TO A PREDETERMINED POSITION BY DETECTING THE NUMBER OF ROTATIONS OF A MOTOR - An electric foldable bed capable of being adjusted to a memorized position has a fold bed having motors connected to a headboard and a footboard. A microcomputer is installed on the bed frame and used for controlling the motors. The microcomputer has a computing section, a memory section, a register section and a comparing section. The computing section detects a position of each motor and computes elevation angle data provided by the memory section, the register section and the comparing section. The memory section is used to store predetermined elevation angle data, the register section is used to receive control commands and store the elevation angle data input by the computing section. The comparing section is used for comparing the elevation angle data from both the memory section and the register section. The sensor is installed onto each motor and used for sensing a rotational number count of the motor.||11-10-2011|
|20110101749||LOWER-BACK SUPPORTING STRUCTURE FOR A BED OR A CHAIR - A lower-back supporting structure for a bed or a chair includes a sliding base, two scissor lifts, a driver and a supporting member. The sliding base has a pair of slide slots and a pair of rotating pins, a securing portion between the two rotating pins, and a plurality of the locking apertures. Two scissor lifts both have an X-shaped frame having a pivot. A driver has a positioning end, an extendable rod, a through hole and a sliding rod placed through the slide slot, the through hole and the first front cotter holes. A supporting member has a pair of slide tracks and a pair of rotating holes. The driver drives the sliding rod along the slide slot of the sliding base to shorten the extendable rod, the scissor lifts rotate around the pivots to lift such that the supporting member is pushed away from the sliding base.||05-05-2011|
|20110094032||SINGLE DRIVER CONNECTING STRUCTURE FOR AN ELECTRIC BED OR CHAIR - A single driver connecting structure for an electric bed or chair comprises: a primary frame, a driver and a link rod. The second structural component has two first angle brackets, and the first angle brackets each include a sliding slot. The third structural component has two second angle brackets, and each second angle bracket includes an aperture. The driver has a positioning portion and an extendable rod, and the positioning portion is pivoted to the securing aperture. The link rod has a first aperture and a second aperture. The first aperture is pivoted to the through hole of the driver with a control pin, and the control pin is slibable in, and limited in, the sliding slot. The second aperture and the aperture of the third structural component are pivoted together such that the driver drives the link rod to affect different movements of the main frame.||04-28-2011|
