Abstract
A hinge includes a bracket, two fixing seats pivotally connected to the bracket, at least one base, at least one first arm pivotally connected between the at least one base and the at least one fixing seat and at least one second arm pivotally connected between the at least one base and the at least one fixing seat. At least one spring is provided between the at least one second arm and the at least one base such that when both the at least one first and second arms are pivoted relative to the at least one base, the required recovery force is provided to facilitate the upward movement of the bracket relative to the at least one base.
Claims20
A hinge comprising:
- an elongated bracket adapted to be securely connected to a display;
- at least one fixing seat pivotally connected to the bracket and having two pairs of through holes respectively defined in a top portion and a bottom portion of the fixing seat;
- at least one base adapted to securely connected to a support and having two upright walls each having a first pivot hole and a second pivot hole;
- at least one first arm having a first end pivotally connected to the first pivot holes of the two upright walls and a second end pivotally connected to one of the two pairs of through holes;
- and
- at least one second arm having a first end pivotally connected to the second pivotal holes of the two upright walls and a second end pivotally connected to the other pair of the two pairs of through holes of the fixing seat such that the display attached to the bracket is able to have height and angle adjustment,
- wherein a side face of the two upright walls is formed with a saddle having positioning recesses defined therein and a limiting block is formed on a side face of the at least one second arm to correspond to the positioning recesses such that when the at least one second arm is pivoted relative to the base, the limiting block is moving in the positioning recesses to provide a temporary positioning effect to the at least one second arm.
A hinge comprising:
- an elongated bracket adapted to be securely connected to a display;
- at least one fixing seat pivotally connected to the bracket and having two pairs of through holes respectively defined in a top portion and a bottom portion of the fixing seat;
- at least one base adapted to securely connected to a support and having two upright walls each having a first pivot hole and a second pivot hole;
- at least one first arm having a first end pivotally connected to the first pivot holes of the two upright walls and a second end pivotally connected to one of the two pairs of through holes;
- at least one second arm having a first end pivotally connected to the second pivotal holes of the two upright walls and a second end pivotally connected to the other pair of the two pairs of through holes of the fixing seat such that the display attached to the bracket is able to have height and angle adjustment, wherein the at least one fixing seat has two positioning wedges formed on a side face of the at least one fixing seat;
- and
- a second washer assembly applied to a pivotal engagement between the fixing seat and the bracket, wherein the second washer assembly has a stop formed to correspond to the two positioning wedges so that when the bracket is pivoted relative to the at least one fixing seat, movement of the stop between the two positioning wedges prevents excessive travel of the display.
