BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an adjustable pivoting device, and more particularly to an adjustable pivoting device for a panel display to allow a stand to be adjusted to different positions for freely changing a status or an angle of the panel display.

2. Description of Related Art

Progression of technology has created various electronic products with multitudes of functions including notebooks, panel displays and smart phones. A panel display may be implemented as a computer monitor, television, digital photo frame, touch panel or the like and is mounted with a stand that supports the weight of the panel display and allows the panel display to be held securely and stably on a determined plane.

However, the conventional stand is securely mounted on the panel display, or alternatively, pivotally mounted on the panel display and pivots between a folding position and a standing position. Thus, people can't adjust the stand to different positions that support the panel display in any determined status or angle. This makes the stands not convenient to use.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide an adjustable pivoting device for panel display that is mounted on a panel display and allows a stand to be adjusted to different positions for freely changing a status or an angle of the panel display.

To achieve the objective, the adjustable pivoting device for panel display comprises a body and a mounting assembly.

The body is mounted securely on a back of the panel display and has a controller and at least one motivating element. The controller is capable of longitudinal movement relative to the body and has a resilient element and at least one actuating slot. The resilient element is connected between the body and the controller and provides a restoration force to the controller. The actuating slot is slantwise formed through the controller. The motivating element is capable of transversal movement relative to the body and has an inner end, an outer end, an engaging element and a latch. The engaging element is mounted in the inner end of the motivating element and is slidably mounted in the actuating slot of the controller, thereby the motivating element is moved transversely when the controller is moved longitudinally. The latch protrudes from the outer end of the motivating element.

The mounting assembly comprises two mounting tabs and at least one latching element. The mounting tabs are separately mounted on the body and are pivotally mounted with a stand. The at least one latching element rotates simultaneously with the stand, and each has a side edge selectively corresponding to the latch of the motivating element, and multiple teeth protrude from the side edge and selectively engage the latch to limit a rotation of the stand.

When adjusting an angle of the stand, the controller is pulled upward to make the motivating element moving inward and disengaging the latches from the teeth of the latching elements, such that the stand can be pivoted to a determined position.

Accordingly, the adjustable pivoting device in accordance with present invention allows the stand to be adjusted to different positions for freely changing a status or an angle of the panel display and provide convenience in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference toFIGS. 1,2,3and4, The adjustable pivoting device in accordance with present invention is mounted onto a back of a panel display such as a digital photo frame (40) and comprises a body (10), a mounting assembly (20) and a cover (30).

Preferably, the body (10) comprises a mounting bracket (11), a controller (12), two resilient elements (13) and two motivating elements (14).

The mounting bracket (11) is mounted securely on a back of the digital photo frame (40) and has two elongated holes (112) and two hooks (111). The elongated holes (112) are separately formed transversely through the mounting bracket (11). The hooks (111) are separately formed on the mounting bracket (11).

The controller (12) is mounted on the mounting bracket (11), is slidable longitudinally relative to the mounting bracket (11) and has a middle portion, two side portions, multiple longitudinal slots (120), two actuating slots (121), two buckles (122) and multiple fasteners (123). The longitudinal slots (120) are separately formed longitudinally through the middle portion of the controller (12). The actuating slots (121) are slantwise formed respectively through the side portions of the controller (12). The buckles (122) are respectively formed in two sides of the controller (12). The fasteners (123) extend respectively through the longitudinal slots (120) of the controller (12) and secured in the mounting bracket (11), thereby allow a longitudinal slide of the controller (12) relative to the mounting bracket (11).

The resilient elements (13) are connected to two sides of the controller (12), and each resilient element (13) has two ends connects respectively to one of the hooks (111) of the mounting bracket (11) and a corresponding one of the buckles (122) of the controller (12), thereby provides a restoration force to the controller (12).

The motivating elements (14) are transversely mounted oppositely on the mounting bracket (11) beside the controller (12) and are transversely slidable relative to the mounting bracket (11). Each motivating element (14) has an inner end, an outer end, multiple transversal slots (141), multiple bolts (143), an engaging element (142) and a latch (140). The transversal slots (141) are separately formed transversely through the motivating element (14). The bolts (143) extend respectively through the transversal slots (141) of the motivating element (14) and are secured in the mounting bracket (11), thereby allow a transversal slide of the motivating element (14) relative to the mounting bracket (11). The engaging element (142) slidably extends through a corresponding actuating slot (121) of the controller (12), is secured in the inner end of the motivating element (14) and is slidably mounted through a corresponding elongated hole (112) of the mounting bracket (11). Accordingly, the motivating element (14) is moved inward when the controller (12) moves upward as shown inFIG. 5. The latch (140) protrudes from the outer end of the motivating element (14).

The mounting assembly (20) comprises two mounting tabs (21), two pintles (210) and two latching elements (22). The mounting tabs (21) are separately mounted on the body (10) and are pivotally mounted with a stand (41). The pintles (210) are rotatably mounted respectively through the mounting tabs (21), and each pintle (210) is mounted around by multiple spacers (211) and is secured by a fixing element (212). The latching elements (22) are respectively mounted around the pintles (210), and each latching element (22) has a boss (220), a side edge and multiple teeth (221). The boss (220) is secured in a surface of the stand (41) to make the latching element (22) rotates simultaneously with the stand (41). The side edge selectively corresponds to the latch (140) of the motivating element (14). The teeth (221) protrude from the side edge of the latching element (22), and each two adjacent teeth (221) define a gap that selectively engage the corresponding latch (140) to limit a rotation of the latching element (22) and the stand (41) as shown inFIG. 6.

The cover (30) is detachably mounted on the mounting bracket (11) to cover the body (10) and the mounting assembly (20) and has a top and a notch (31) formed on the top. The notch (31) corresponds to and allows the controller (12) to protrude out from the notch (31), thus facilitates an operation of the controller (12).

With further reference toFIG. 7, when adjusting an angle of the stand (41), the controller (12) is pulled upward to make the motivating element (14) move inward and disengages the latches (140) from the teeth (221) of the latching elements (22), and the stand (41) can be rotated to a determined position. Then, the controller (12) is released and the latches (140) and the teeth (221) will reengage with each other via the restoration force provided by the resilient elements (13).

Accordingly, the adjustable pivoting device in accordance with present invention allows the stand (41) to be adjusted to different positions for freely changing a status or an angle of the panel display and is convenient in use.
