## Background
BACKGROUND
1. Technical Field
The present disclosure relates to a display support device.
2. Description of Related Art
Flat screen displays, such as popular liquid crystal displays, are commonly supported by a support that is set on a table, desk, or wall that can adjust the height and the view angle. Typically, the flat screen displays are fixed to the support by screws locked into screw holes that are defined in a back portion of the flat screen displays. However, different sized flat screen displays have different positions for the screw holes, so that different supports are needed to accommodate different sized flat screen displays, which limit the usage of the supports.

DETAILED DESCRIPTION
The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIGS. 1 and 2, an embodiment of a display support device includes a support base 110, a connecting member 100, a frame 160, a number of first fasteners 170, and an expanding bracket 180.
The connecting member 100 includes a telescopic rod 120, a connecting bracket 130, a clip 140, a connecter 150, and a number of second fasteners 190.
The fixing base 110 includes a substrate 112 and a hollow pole 114. The substrate 112 includes a connecting plate 112a and two approximately L-shaped latching plates 112b. The latching plates 112b is substantially perpendicularly positioned on opposite sides of the connecting plate 112a. The pole 114 is substantially perpendicularly mounted on the connecting plate 112a. A threaded hole 114a is defined in the periphery of the pole 114 and communicates with the inner space of the pole 114. In this embodiment, the display support device is set on the ground by the substrate 112. In other embodiment, the display support device can be hung on a ceiling or can be mounted to a sidewall of a house by the substrate 112.
The telescopic rod 120 is substantially L-shaped and includes a vertical sliding portion 122 slidably received in the pole 114 and a horizontal connecting portion 124. The sliding portion 122 defines a sliding slot 120a along the longitudinal direction. The fastener 190 extends through the threaded hole 114a and is adjustably fastened in the sliding slot 120a of the telescopic rod 120, thus adjustably positioning the telescopic rod 120 in the pole 114.
The connecting bracket 130 includes two overhanging arms 132 and a connecting pin 134 perpendicularly connecting the overhanging arms 132. The connecting portion 124 is sandwiched by the overhanging arms 132, and the overhanging arms 132 are adjustably mounted on the connecting portion 124 with the second screws 190.
The clip 140 includes an end plate 142 and two side plates 144 perpendicularly extending from two opposite sides of the end plate 142. A first hole 142a is defined in the middle of the end plate 142 for allowing the connecter 150 such as a bolt to pass through and pivotally connect the frame 160 to the clip 140. Two second holes 144a are respectively defined in the side plates 144 and aligned with each other. The clip 140 is pivotally mounted on the connecting pin 134 through the second holes 144a of the side plates 144.
The frame 160 includes a hold plate 162 and a circular bump 164 formed on the back of the hold plate 162. The hold plate 162 is substantially rectangular and defines two symmetrical slots 162a through the hold plate 162. A threaded hole 164a is defined in the middle of the bump 164 for mating with the connecter 150 thereby pivotally connecting the frame 160 to the clips 140.
The expanding bracket 180 includes two first expanding bars 182 and two second expanding bars 184. Each of first expanding bars 182 defines a number of through holes 182a. Each of the second expanding bars 184 defines two symmetrical mounting holes 184a and two symmetrical slots 184b, and the fixing holes 184a are positioned between the slots 184b. Four first screws 170 slidably extend through the slots 162a and lock into the four fixing holes 184a of second expanding bars 184, so that the second expanding bars 184 are perpendicular to the slots 162a and mounted on the hold plate 162. Four first fasteners 170 slidably extend through the four slots 184b of the second expanding bars 184 and engage in four of the through holes 182a to make the first expanding bars 182 substantially perpendicular to the second expanding bars 184 and fix a display 200 (shown in FIG. 3).
In another embodiment, the two slots 184b of each second expanding bars 184 may be joined together as one elongated slot, and the first fasteners 170 may extend through the slots 162a and the elongated slot 184b to mount the second expanding bars 184 to the hold plate 162.
Referring to FIG. 3, in use, the connecting pin 134 of the connecting bracket 130 serves as a pivotal shaft, which ensures the display 200 to be able to rotate at any desired angle in the horizontal plane. The connecter 150 serves as another pivotal shaft that ensures the display 200 to be able to rotate at any desired angle in a vertical plane perpendicular to the horizontal plane. The height of the display 200 relative to the fixing base 110 can be changed by moving the telescopic rod 120 relative to the pole 114 of the base 110. Furthermore, the first fasteners 170 are adjusted to change the distance between the first expanding bars 182 and the distance between the second expanding bars 184 to accommodate displays of different sizes.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
