Abstract: A climate control system provides the desired climate conditions of temperature and humidity at a contact surface of a multi-layered structure. The climate control system includes a heating mechanism disposed between one or more foam layers of structure and configured to deliver heat to the contact surface and a separate cooling mechanism disposed in the foam layers. The cooling mechanism includes at least one fan assembly, air channels and reticulated foam layers configured to draw air away from the contact surface toward the bottom of the structure. An operational control system is used to control the heating mechanism and cooling mechanism to achieve the desired climate conditions on the contact surface in accordance with a desired time-based climate control algorithm.

Abstract: An electric drive mechanism for a recliner chair having a base mount and a moveable frame pivotally connected with the base mount includes a fixation frame detachably mounted to the base mount, a push frame pivotally connected with the fixation frame and located below the moveable frame, and an actuator pivotally connected with the fixation frame and the push frame, such that the push frame is driven by the actuator to swing relative to the fixation frame. When the push frame swings upwardly, a front end portion of the push frame pushes the moveable frame to swing upwardly. A user lying on the recliner chair can easily control the swing angle of movable frame so as to lie on the recliner chair with a relaxed posture.

Abstract: A hinge includes identical first and second members each having a base portion with an end surface, a long arm with a pivot hole and a middle abutment surface and a short arm with a rear abutment surface both extending from the end surface, and a protrusion at a distal end of the long arm. Each protrusion has a front abutment. A pivot is inserted through the pivot holes to couple the first and second members in a way that the hinge is limited in a range of pivotal angle.

Abstract: An electric bed includes a base, a back frame, and a butt frame. The rear end of the back frame is attached to the base, and the back frame is swingable relative to the base by the driving of a first actuator. The butt frame is located in back of the back frame. The rear end of the butt frame is attached to the base, and the butt frame is swingable relative to the base by the driving of a second actuator. As a result, the electric bed of the invention enables the user to change the posture thereof between sitting and flat lying postures through the swinging of the back frame, and effectively supports the waist of the user through the swinging of the butt frame, so that the user can maintain the posture thereof conforming to ergonomics, thereby prevented from hurt on the waist.

Abstract: An electric bed frame for connection with a bed frame includes a fixed rack, a movable rack, a hitching bracket and a fastener. The fixed rack has a through hole. The movable rack is movably attached to the fixed rack. The hitching bracket has a striding portion for being disposed on a side rack of the bed frame, and an extended portion extended from the striding portion and having a groove. The fastener is inserted through the through hole of the fixed rack and the groove of the hitching bracket for connecting the hitching bracket with the fixed rack. As a result, the user has no need to throw away the normal bed existing at home and buy a whole new electric bed, and can enjoy the lifting and lowering effect like the electric bed on the existing normal bed.

Abstract: An electric bed includes a base frame, a movable frame slidably disposed on the base frame and moveable backward and forward, a back frame having a rear end pivotally connected with the movable frame, and a driving member extendable and retractable in length, having a rear end pivotally connected with the movable frame and located below the rear end of the back frame, and a front end pivotally connected with the back frame. A linkage has a front end pivotally connected with the base frame, and a rear end pivotally connected with the back frame and located between the rear end of the back frame and the front end of the driving member. When the driving member extends longer, the back frame is rotated upwardly to enable the rear end of the back frame and the movable frame to horizontally move forward together.

Abstract: An electric bed includes a base, a back supporting unit pivotally connected with the base, a first actuator to drive the back supporting unit to upwardly and downwardly swing relative to the base, a head supporting unit pivotally connected with the back supporting unit, and a second actuator to drive the head supporting unit to swing between an initial position and a head-up position relative to the back supporting unit. When the head supporting unit stays at the initial position, a head supporting surface of the head supporting unit is flush with a back supporting surface of the back supporting unit. The head-up position is lower than the initial position.
