Abstract

A hanger for an electronic apparatus. The hanger comprises a base mounted to a wall, a bracket pivoting on the base, a first link pivoting on the base and comprising a ratchet with a plurality of teeth, and a second link with a stopper rotatably connecting the first link and the bracket. The angle between the bracket and the base is varied by the stopper engaging each tooth of the ratchet. The bracket can rotate between a first position and a second position. When the bracket is in the first position, the bracket overlaps the base, and in the second position, the angle between the bracket and the base is maximized.

Claims

1. A hanger for an electronic apparatus, comprising:

a base mounted on a wall;

a bracket pivoting on the base;

a first link pivoting on the base and having a ratchet with a plurality of teeth; and

a second link rotatably connecting the first link and the bracket and having a stopper,

wherein the bracket rotates between a first position and a second position, the angle between the bracket and the base is varied by the stopper engaging each tooth of the ratchet, and the teeth are inclined toward the base, whereby the angle between the bracket and the base is adjustable when the bracket rotates from the first position to the second position and is not adjustable when the bracket rotates from the second position to the first position further comprising a reset plate pivoting on the first link and rotating along with the second link, wherein the reset plate releases the engagement of the stopper and the teeth when the bracket is in the first position, and the stopper engages the teeth again when the bracket is in the second position.

2. The hanger as claimed in claim 1, wherein, when in the first position, the bracket overlaps the base, and when in the second position, an angle between the bracket and the base is maximized.

3. The hanger as claimed in claim 1, wherein the reset plate has a first portion higher than the teeth and a second portion lower than the teeth, and when the bracket is in the first position, the stopper abuts the first portion of the reset plate, thereby releasing the engagement of the stopper and the teeth, and when the bracket is in the second position, the stopper abuts the second portion, thereby the stopper engaging the teeth again.

4. The hanger as claimed in claim 3, wherein the reset plate has a protrusion between the first and second portions, and the protrusion has a first side adjacent to the first portion and a second side adjacent to the second portion;

whereby, when the bracket is in the first position, the stopper abuts the first side and thereby abuts the first portion, and, when the bracket is in the second position, the stopper abuts the second side and thereby abuts the second portion.

5. The hanger as claimed in claim 4, wherein the first link has a first tab and a second tab, and, when the bracket is in the first position, the reset plate abuts the first tab, whereby the stopper abuts the first portion, and, when the bracket is in the second position, the reset plate abuts the second tab, whereby the stopper abuts the second portion.

6. The hanger as claimed in claim 1, wherein the second link has a bias element biasing the stopper to maintain the engagement of the stopper and the teeth.

7. The hanger as claimed in claim 6, wherein the bias element is a compression spring.

8. The hanger as claimed in claim 1, further comprising a joint element which joins the bracket and the electronic apparatus.

9. The hanger as claimed in claim 1, further comprising a panel mounted on the wall, the base being secured to the panel.

10. The hanger as claimed in claim 9, wherein the panel has a level adjusting the horizontal state of the panel.
