Abstract:
A support stand includes a supporting leg and a hinge subassembly. The supporting leg includes a connecting portion. The hinge subassembly includes a shaft and a leaf rotatably sleeved on the shaft. The shaft has a connecting portion engaging with the connecting portion of the supporting leg. One of the connecting portions of the supporting leg and the shaft is a connecting slot, and the other one of the connecting portions of the supporting leg and the shaft is a protrusion engaged in the connecting slot, thus fixing the shaft to the supporting leg. A friction is created between the shaft and the leaf.
Abstract:
An exemplary hinge positioning structure (20) includes a base (22), a pivot shaft (24) engaged in the base, a pivot shaft gripper (264), and a resilient member (266). The pivot shaft is rotatably engaged in the base. The pivot shaft gripper is sleeved on the pivot shaft. An end of the pivot shaft gripper is engaged with the base so that part of the pivot shaft gripper is fixed to the base. Two ends of the resilient member are connected to the base and another end of the pivot shaft gripper, respectively. The resilient member applies a force on the pivot shaft gripper so that the pivot shaft gripper tightly grips on the pivot shaft, and the pivot shaft gripper is relaxed by an external force for allowing the pivot shaft to rotate relative to the base. The present invention further provides a hinge positioning unit (26).
Abstract:
The support stand for a flat-panel display monitor includes a rotatable bracket, a hinge assembly, a base member, a first and a second link brackets. The hinge assembly includes a connecting piece, and a pivotal shaft inserted through the connecting piece and the rotatable bracket. The pivotal shaft forms a restricting flange. The base member includes a supporting block forming a restricting pole. The first link bracket forms two limiting protrusions on the first and second end portions. The first end portions of the first and second link brackets are rotatably connected to the connecting piece, the second end portions of the first and second link brackets are rotatably connected to the supporting block. The two limiting protrusions of the first link bracket abut the restricting flange and the restricting pole respectively, thus adjusting the support stand to move between a first utmost position and a second utmost position.
Abstract:
A fastening assembly includes a threaded fastening member, a slidable member, and a resilient member. The threaded fastening member has a threaded portion. The slidable member is slidably sleeved on the threaded fastening member. The slidable member forms a resisting portion defining a threaded hole. The threaded hole is engagable with the threaded portion. The resilient member resists the threaded fastening member and the slidable member. The threaded portion of the threaded fastening member extends through the threaded hole.
Abstract:
A support stand for a flat-panel display monitor, includes a base member and an elevating mechanism positioned on the base member. The elevating mechanism includes a support bracket including base portion, an elevating member slidably connected to the support bracket, a pair of guiding members fixed on the support bracket, a pair of rollable members connected to opposite sides of the elevating member, and a resilient member. Each guiding member includes a guiding surface and a distance between the guiding surfaces decreases from an upper end to a lower end of each guiding member. The rollable members move along the guiding surface. The resilient member is positioned between the rollable members to push the rollable members to press the guiding surfaces.
Abstract:
A hinge mechanism includes two pivoting shafts substantially parallel to each other, two main gears non-rotatably sleeved on the pivoting shafts, respectively. The hinge mechanism further includes two transmission gears positioned between the main gears, and two brackets sleeved on the pivoting shafts, respectively. Each transmission gear meshes with the other transmission gear and one main gear. Each pivoting shaft includes a flange which defines two locking portions, and each bracket forms two latching portions engaging with the locking portions of each pivoting shaft. The locking portions and the latching portions are selected from the structures of groove and hook.
Abstract:
An exemplary sliding mechanism (10) includes a main plate (11), a slide plate (12) slidably connected to the main plate (11), and a linkage module positioned between the main plate (11) and the slide plate (12). The linkage module includes an elastic member (15) and a guiding shaft (17). The elastic member (15) is sleeved on the guiding shaft (17). Two ends of the guiding shaft (17) is rotatably connected to the main plate (11) and the slide plate (12) respectively. The elastic member (15) is configured for driving the slide plate (12) and enabling the slide plate (12) to slide along the main plate (11) after the slide plate (12) is manually moved to a predetermined position with respect to the main plate (11).
Abstract:
A hinge assembly includes a pivot shaft having a pivot portion, a friction member sleeved on the pivot portion, a support member, and an adjusting member. The pivot shaft includes a pivot portion. The friction member includes a first friction body and a second friction body attached to the first friction body. The support member includes a housing, and defines a receiving chamber in the housing and an adjusting hole communicating with the receiving chamber. The friction member and the pivot portion of the pivot shaft are received in the chamber. An inner wall of the receiving chamber presses the friction member to clamp the pivot portion. The adjusting member is received in the at least one adjusting hole to abut the friction member such that the friction created between the friction member and the pivot portion can be adjusted.
Abstract:
A support mechanism includes a base and a lifting mechanism mounted on the base. The base defines a limiting slot. The lifting mechanism includes a first arm, a second arm, a connecting mechanism including a rod, and an elastic member. The first arm has a first end and a second end and includes a limiting member slidably received in the limiting slot. The second arm has a second end and a first end adjacent to the first end of the first arm and away from the second end of the first arm. The connecting mechanism includes a rod. The elastic member is connected to the first end of the first arm and the first end of the second arm. The first end of the first arm and the rod are pivotally connected to the base, and the first end of the second arm pivotally connects to the rod.
Abstract:
An exemplary hinge assembly includes a shaft, a cam, a cam follower, a first elastic member, a second elastic member, a first sleeve, a second sleeve. The cam and the cam follower are sleeved on the shaft. The first elastic member is sleeved on the shaft, and configured for producing an elastic force along the shaft. The first sleeve is sleeved on the shaft, and non-rotatably connected to the cam follower. The second sleeve is sleeved on the shaft, and non-rotatably connected to the cam. The second elastic member is sleeved on the shaft, and configured for producing an elastic force for driving the first sleeve to rotate relative to the second sleeve. The controlling member resists one of the cam and cam follower, and capable of driving the cam away from the cam follower.
