Abstract:
Disclosed herein are various embodiments of mechanisms, which may be used in portable terminals. In an example embodiment, a mechanism generally includes a stopper and first and second plates slidably coupled to each other. A first portion of the stopper is engaged within an opening of the first plate. A second portion of the stopper is slidably received within a guide slit of the second plate. The stopper is coupled to the first plate for common movement therewith such that the second portion of the stopper slides within the guide slit when the second plate slides relative to the first plate. The stopper may thus be operable for restricting sliding movement of the second plate relative to the first plate between a closed position in which the second portion of the stopper is engaged with a first end portion of the guide slit and an open position in which the second portion of the stopper is engaged with a second end portion of the guide slit.

Disclosed herein are various embodiments of slide actuators, which may be used in portable terminals. In an example embodiment, a slide actuator generally includes one or more elastic members having one or more expandable and contractible unit elastic sections or corrugated portions. A framework is coupled to the one or more elastic members.
Abstract:
A slide assembly includes first and second slider members. The second slider member is coupled to the first slider member and slidable relative to the first slider member between a closed position and an open position. The first slider member includes an arm stopper having first and second side portions. The second slider member includes a slot extending along a sliding direction of the slide assembly. A housing is coupled to the first slider member. A rotator is rotably mounted within the housing. Also within the housing is a liquid damping substance with a viscosity for resisting rotation of the rotator. An arm is coupled to the rotator such that the rotator rotates when the arm is pivoted. The arm is slidably engaged with the slot such that the arm moves linearly relative the slot until a corresponding end portion of the slot causes the arm to pivot generally between the first and second side portions of the arm stopper. The liquid damping substance generates a damping force generally opposing the rotation of the rotator. The damping force helps reduce the sliding speed of the second sliding member relative to the first sliding member when the slide assembly is approaching the open position or the closed position.
Abstract:
Slide actuators for portable communications terminals having a first body and a second body slideably movable relative to the first body. An exemplary embodiment of a slide actuator includes a guide rail assembly for coupling to first and second bodies of a portable communications terminal. A biasing assembly is coupled to the guide rail assembly. The guide rail assembly includes a guide rod. The guide rail assembly is configured to translate a generally linear motion of the second body relative to the first body to a rotational motion of the guide rod. The biasing assembly is configured for connection to the first body. The biasing assembly is configured to provide a biasing force toward a first rotational rest position and a second rotational rest position of the guide rod.
Abstract:
Exemplary embodiments are provided of a coupling assembly that moveably couples a first body member of an electronic device and a second body member of the electronic device. The coupling assembly includes a slotted member that defines a slot therein, an arm, and a fastener that couples the arm to the first body member. Further, the coupling assembly includes a slide coupling that is received by the slot so as to moveably couple the arm to the second body member. In addition, the coupling assembly includes a biasing member that biases the slide coupling away from the fastener to thereby bias the second body member relative to the first body member.
Abstract:
Exemplary embodiments are provided of a stand hinge for a portable terminal with a main body. In one exemplary embodiment, the stand hinge includes a support member rotatably coupled to the main body. The stand assembly also includes a retaining member and a stop member that each engage the support member to limit rotation thereof. Furthermore, the stand assembly includes a connector member that couples the retaining member and the stop member such that the retaining member and the stop member cooperatively move relative to the support member.

Abstract:
A hinge assembly generally includes a first frame assembly configured to be coupled to the first body of the portable communications device, and a second frame assembly configured to be coupled to the second body of the portable communications device. The example hinge assembly also generally includes a first drive assembly, and a second drive assembly. A center shaft couples the first drive assembly to the second drive assembly such that the first drive assembly is pivotable about the center shaft relative to the second drive assembly. In addition, the first and second drive assemblies support hinged movement of the first frame assembly relative to the second frame assembly between at least a closed position and an open position.
Abstract:
Exemplary embodiments are provided of hinge assemblies for rotatably coupling a support member and a body of a portable communications terminal to allow the support member to be maintained at an angle relative to the body. In one exemplary embodiment, a hinge assembly includes a housing configured to be coupled to a body of a portable communications terminal. A rotation member is configured to be coupled to a support member. A stopper is positioned at least partially within the housing. A biasing member biases the stopper towards the rotation member such that contact between the stopper and the rotation member maintains the support member at an angle relative to the body.
Abstract:
A hinge assembly generally includes a housing configured to be coupled to a portable communications terminal, a shaft coupled to the housing for rotation relative to the housing, and a slider positioned at least partially within the housing. The hinge assembly is suitable for coupling a support member to the portable communications terminal to allow the support member to be rotatably positioned rearwardly of the portable communications terminal to support the portable communications terminal at an inclination angle on a support surface. The shaft is coupled to the support member for conjoint rotation, and the slider is moveable relative to the shaft to selectively resist rotation of the shaft and support member relative to the housing. This can help retain the support member in its rearward position to support the portable communications terminal at the inclination angle on the support surface.
