Abstract: A hinge assembly for use in a flat display monitor includes a support member, a rotational base and a pivot mechanism for rotatably connecting the rotational base to the support member. The support member includes two first sidewalls, a first resisting surface and a second resisting surface. Each first sidewall defines a pivoting hole. The pivot mechanism includes a pivotal shaft, a limiting washer and a fixing element. The pivotal shaft includes a shaft portion running through the pivoting bole. The pivotal shaft is non-rotatable relative to the support member. The limiting washer includes a first restricting surface and a second restricting surface. The limiting washer is non-rotatable relative to the rotational base with the first restricting surface and the second restricting surface configured for resisting the first resisting surface and the second resisting surface respectively.

Abstract: An exemplary hinge assembly (300) for use in a flat display monitor includes a support member (10), a rotational base (20) and a pivot mechanism (30) for rotatably connecting the rotational base to the support member. The rotational base includes a fixing board (22) and a side board (24) disposed at an end of the fixing board, the side board defining an engaging hole (242) and forming an inwardly bent portion (240) at a distal end edge thereof. The support member includes an extending seat (16) defining a round pivoting hole (1601), and a retaining portion (161) extending from an exterior side of the extending seat. The retaining portion of the side board is configured for blocking the inwardly bent portion of the side board so that a range of rotation of the rotational base relative to the support member is between a first utmost position and a second utmost position.

Abstract: An exemplary hinge assembly (300) for use in a flat display monitor (400) includes a support member (10), a rotatable base (20) and a pivot mechanism (30) for rotatably attaching the rotatable base and the support member together. The rotatable base includes a fixed board (22) and a side board (24) disposed at an end of the fixed board, and the side board forms a stopper (244). The pivot mechanism is rotatably connected to the rotatable base and non-rotatably connected to the support member. The pivot mechanism includes a pivotal shaft. The pivotal shaft defines a limited guide groove (3013) configured for blocking the stopper of the side board so that a range of rotation of the rotatable base relative to the support member is between a first utmost position and a second utmost position.

Abstract: A hinge assembly (300) for use in a flat display monitor includes a support member (10), a rotational bracket (20) and a pivot mechanism (30) for rotatably connecting the rotational bracket to the support member. The support member includes an extending seat (16) defining a restricting groove (162) thereof. The pivot mechanism includes a pivotal shaft (301), a torsion spring (302), and a stop (303). The torsion spring is disposed around the pivotal shaft for providing torsion force. The pivotal shaft is fixedly connected to the rotational bracket and rotatably connected to the rotational bracket. The stop is fixed at end of the pivotal shaft and is rotatable in the restricting groove corresponding to rotation of the rotational bracket relative to the support member, with the stop being rotatable between a first utmost position and a second utmost position.
