Abstract:
An exemplary hinge assembly (10) includes a base body (12), a bracket (14), a support board (18), a pivotal mechanism (16) and a rotational mechanism. The pivotal mechanism includes a pivotal shaft (163) fixed to the base body and rotatable relative to the bracket, an elastic member (165) and a fixing member (167). The rotational mechanism includes a rotational shaft (191), a rotary member (193), a steady member (195) and an elastic member (197). The support board and the rotary member are rotatable relative to the steady member, the base body, the bracket and the pivotal mechanism around a second axis. Each of the rotary member and the steady member defines an engaging surface (1932, 1951). One of the engaging surfaces forms at least one peak (1933), and the other of the engaging surfaces defines at least one valley (1953) corresponding to the peak.
Abstract:
An exemplary adjustable stand (20) for displays includes a main support (22), a movable rack (25), an adjusting system (26) and a balance mechanism (28). The movable rack is slidably mounted on the main support. The adjusting system includes at least one pinion gear (266) rotatably attached on the movable rack and at least one rack gear (267) fixed to the main support. The at least one pinion gear meshes with the at least one rack gear. The balance mechanism is mounted between the main support and the movable rack for balancing gravity of the movable rack and components fixed relative to the movable rack. The present invention further discloses a stand (10) including a support bracket (30), a base (40) and the adjustable stand for connecting the support and the base.
Abstract:
A hinge assembly (10) for interconnecting a main body and a cover of a portable electronic device includes a hinge housing (20), and a first hinge apparatus (30) and a second hinge apparatus (40) rotatably contained in the housing and being perpendicular to each other. The first hinge apparatus includes a cam (36) rotatably attached to the housing and fixed to the main body, and other elements housed in the housing and fixed relative thereto. The second hinge apparatus includes a boom (43), a support (41) rotatably attached to the boom and fixed to the housing, and a pair of wings (433) extending from the boom and fixed to the cover. The cover is opened relative to the main body by being rotated about an X-axis of the first hinge apparatus. The cover is then rotated relative to the housing about a Y-axis of the second hinge apparatus.
Abstract:
An exemplary stand (60) includes a housing (610), an adjustable base (68), a pulley (630), a sleeve (635), a rotating member (636), a resilient member (632), a sliding member (62), and a cable. The adjustable base is fixed to one end of the housing. The adjustable base has a driving component (681), a follower (682), and a rotation shaft (683). The driving component is configured to rotate the follower. The rotation shaft is fixed to the follower. The pulley is rotatably connected to the housing. The sleeve is slidably disposed on the housing, and engages the rotation shaft. The rotating member is rotatably received in the sleeve. The resilient member is fixed to the adjustable base. The cable partially coils around the pulley, and connects the resilient member to the rotating member. A sliding member is slidably connected to the housing and fixed to the cable.
Abstract:
An exemplary elevator (50) includes a support mechanism (51), an elevating mechanism (52), and an adjusting mechanism (53). The support mechanism includes a support bracket (511) and a coil spring (514). The elevating mechanism includes a rotatable member (521) rotatable attached to the support bracket, a driven member (524) fixed to the rotatable member, a sliding bracket (526) slidably connected to the support bracket, and a sliding member (527) fixed to the sliding bracket. The sliding member is capable of engaging with the rotatable member for converting rotation to linear motion. The adjusting mechanism includes a diver capable of engaging with the driven member and driving the driven member to rotate. A bottom end of the support bracket is fixed to the adjusting mechanism. An end of the coil spring is fixed on the sliding bracket, and another end of the coil spring is connected to the support bracket.

Abstract:
An exemplary adjustable support mechanism (50) includes a main bracket (51), an adjustable suspension member (52) slidably mounted to the main bracket and an elastic member (53). The main bracket forms at least two guide rails (516) including a first guide rail and a second guide rail disposed opposite to each other. The adjustable suspension member includes two crossed connected suspension frames (524, 525), at least two wheels (522) engaging the guide rails, and at least one stretching member (526, 527). The suspension frames are rotatably connected to each other. The at least two wheels are disposed at ends of the suspension frames. Two ends of each stretching member are connected to the suspension frames correspondingly. The elastic member has two ends fixed relative to the main bracket and the adjustable suspension member correspondingly.
