Abstract

An adjustable pivoting device for panel display has a body and a mounting assembly. The body has a controller that is capable of longitudinal movement and two motivating elements that are capable of transversal movement. The controller has actuating slots formed slantwise through the controller. Each motivating element has a latch and an engaging element slidably mounted in one of the actuating slots of the controller, thereby the motivating elements are moved transversely when the controller is moved. The mounting assembly is pivotally mounted with a stand and has two latching elements that rotate simultaneously with the stand and has multiple teeth selectively engage the latches to limit a rotation of the stand. Accordingly, the adjustable pivoting device allows the stand to be adjusted to different positions for freely changing a status or an angle of the panel display and is convenient in use.

Claims

1. An adjustable pivoting device for being pivotally mounted a stand on a back of a panel display and comprising

a body comprising

a mounting bracket;

a controller being mounted on the mounting bracket, being longitudinally slidable relative to the mounting bracket and having

a middle portion; and

at least one actuating slot being slantwise formed through the controller;

at least one resilient element having two ends connecting respectively to the mounting bracket and the controller; and

at least one motivating element being transversely mounted on the mounting bracket, being transversely slidable relative to the mounting bracket and having

an inner end;

an outer end;

an engaging element secured in the inner end of the motivating element and being slidably mounted through a corresponding actuating slot of the controller; and

a latch protruding from the outer end of the motivating element; and

a mounting assembly comprising

two mounting tabs being separately mounted on the body;

two pintles being rotatably mounted respectively through the mounting tabs for pivotally mounting the stand with the mounting tabs; and

at least one latching element being respectively mounted around at least one of the pintles and each one of the at least one latching element having

a boss being adapted to be secured in a surface of the stand to make the latching element rotating simultaneously with the stand;

a side edge selectively corresponding to the latch of a corresponding one of the at least one motivating element; and

multiple teeth protruding from the side edge of the latching element, and each two adjacent teeth defining a gap that selectively engages the latch on the corresponding motivating element to limit a rotation of the latching element and the stand.

2. The adjustable pivoting device as claimed in claim 1, wherein

the controller of the body has two actuating slots being slantwise formed respectively through two side portions of the controller;

the body has two motivating elements being transversely mounted oppositely on the mounting bracket and corresponding respectively to the actuating slots of the controller; and

the mounting assembly has two latching elements being respectively mounted around the pintles.

3. The adjustable pivoting device as claimed in claim 2, wherein

the mounting bracket of the body further has two hooks being separately formed on the mounting bracket;

the controller further has two buckles being respectively formed in two sides of the controller; and

the body has two resilient elements each having two ends connecting respectively to one of the hooks of the mounting bracket and a corresponding one of the buckles of the controller.

4. The adjustable pivoting device as claimed in claim 1, wherein the controller further has

multiple longitudinal slots being separately formed longitudinally through the middle portion of the controller;

and

multiple fasteners extending respectively through the longitudinal slots of the controller and secured in the mounting bracket.

5. The adjustable pivoting device as claimed in claim 1, wherein each one of the at least one motivating element further has

multiple transversal slots being separately formed transversely through the motivating element;

and

multiple bolts extending respectively through the transversal slots of the motivating element and secured in the mounting bracket.

6. The adjustable pivoting device as claimed in claim 1, wherein each pintle of the mounting assembly is mounted around by multiple spacers and is secured by a fixing element.

7. The adjustable pivoting device as claimed in claim 1 further comprises a cover being detachably mounted on the mounting bracket to cover the body and the mounting assembly and having

a top;

and

a notch formed on the top and corresponding to and allowing the controller of the body to protrude out of the notch.
